  Next, the mountain fold mechanism 60, the valley fold mechanism 70, and the component connection mechanism 66 (66a, 66b) will be described. FIG. 6 is a partially exploded perspective view showing a configuration example (No. 4) of the bag mouth fan forming drive unit 40. Between the upper frames 11a and 11b shown in FIG. 6, there is provided a mountain folding mechanism 60 that constitutes the function of the first folding mechanism. The mountain folding mechanism 60 includes upper guide rails 61a and 61b, upper arms 62a and 62b, and an accordion-shaped upper band 63. A pair of upper guide rails 61a and 61b constituting an example of a first guide member are attached between the front sides of the left and right upper frames 11a and 11b when viewed from the bag insertion direction I.

  The upper guide rails 61a and 61b have an upper chordal arc shape when viewed from the same direction. The two upper guide rails 61a and 61b have a coaxial point (not shown) (corresponding to a virtual origin p, which will be described later), and the track near the center changes from an arc shape to a linear shape. This is to define the binding site q when the package 1 is folded (see FIG. 7).

  A pair of upper arms 62a and 62b are slidably engaged with the upper guide rails 61a and 61b. For example, a pair of openings 64a and 64b is provided on the side surface of one end (near the upper end) of each of the upper arms 62a and 62b. As shown in FIG. 6, the upper guide rail 61a is inserted through the opening 64a, and the upper guide rail 61b is inserted through the opening 64b.

The valley fold mechanism 70 includes lower guide rails 71a and 71b, lower arms 72a and 72b, and a bellows-like lower belt body 73 having an upper chordal arc-shaped belt-like outer shape.

  A pair of lower guide rails 71a and 71b constituting an example of a second guide member are attached between the front sides of the left and right lower frames 21a and 21b when viewed from the bag insertion direction I. The lower guide rails 71a and 71b also have an upper chordal arc shape when viewed from the same direction. The two lower guide rails 71a and 71b have a coaxial point (corresponding to a virtual origin p to be described later), and the track near the center of the lower guide rails 71a and 71b changes from an arc shape to a straight line like the upper guide rails 61a and 61b. It has changed. This is for the reason described above (see FIG. 7).

  A pair of lower arms 72a and 72b are slidably engaged with the lower guide rails 71a and 71b shown in FIG. For example, a pair of openings 74a and 74b are provided on the side surface of one end (near the upper end) of the lower arms 72a and 72b. The lower guide rail 71a is inserted through the opening 74a, and the lower guide rail 71b is inserted through the opening 74b. As the above-described upper guide rails 61a, 61b and lower guide rails 71a, 71b, round bars made of steel, stainless steel, brass, or the like are used which are curved into an arc shape.

  Between the left and right lower arms 72a and 72b shown in FIG. 6, a bellows-like lower belt body 73 having an upper chordal arc-shaped belt-like outer shape is disposed (see FIG. 4). For the lower belt 73, a member having a large number of crease shapes formed in the same manner as the upper belt 63 is used. As shown in FIG. 6, the lower band 73 has a plurality of openings 75a and 75b (not shown) substantially equal to the arrangement pitch ρ of the lower guide rails 71a and 71b in the same manner as the upper guide rails 61a and 61b. Is provided.

  The lower guide rail 71a is inserted into the opening 75a (not shown), and the lower guide rail 71b is slidably inserted into the opening 75b to constitute the valley folding mechanism 70. As a result, the mountain fold mechanism 60 and the valley fold mechanism 70 cooperate in vertical synchronization so that the upper belt 63 and the lower belt 73 are substantially meshed with each other on the folded surface of the bag mouth of the package 1. It can be operated to make a bellows-like crease.

  The shaft mounting member 19a shown in FIG. 6 is provided with a rotation shaft hole (not shown), and the shaft mounting member 19b is also provided with a rotation shaft hole. The upper reinforcing member 12b is provided with a pair of rotating bearing portions 13a and 13b shown in FIG. The rotation shaft hole of the shaft portion mounting member 19a is rotatably supported by the rotation bearing portion 13a of the upper reinforcing member 12b shown in the figure via a shaft support shaft 18a. The other end of the support shaft 18a is locked by a C-shaped retaining ring member (not shown). Similarly, the rotation shaft hole of the shaft portion mounting member 19a is rotatably supported by the rotation bearing portion 13b of the upper reinforcing member 12b via the support shaft 18b. The other end of the support shaft 18b is also locked by a C-type retaining ring member or the like.

  In this example, the upper and lower arms 62a and 62b and the lower arms 72a and 72b are interlocked to drive the mountain fold mechanism 60 and the valley fold mechanism 70. ) Is provided.

  The component coupling mechanism 66a includes a coupling rod 661 and a spherical roller bearing member 665. One end of the connecting rod 661 is swingably connected to a predetermined position of the upper arm 62 a of the mountain folding mechanism 60. For example, a rod receiving portion 67a (see FIG. 4) having a flat cylindrical hole 667 shown in FIG. 4 is attached to a predetermined position on the left side wall of the upper arm 62a.

  The flat cylindrical hole portion 667 is opened toward the lower side of the rod receiving portion 67a. One end of the connecting rod 661 is inserted into the flat cylindrical hole 667 of the rod receiving portion 67a, and the end of the connecting rod 661 is connected to be freely swingable by a rod engaging pin 68a (see FIG. 4). The rod engaging pin 68a is attached from the direction orthogonal to the flat cylindrical hole 667 outside the upper arm 62a.

  The spherical roller bearing member 665 has a rod engagement hole 663 and is provided at a predetermined position on the left side wall of the lower arm 72 a of the valley folding mechanism 70. For example, a spherical roller bearing member 665 fitted with a spherical bearing having a rod engagement hole 663 is attached to a predetermined position on the left side wall of the lower arm 72a. The other end side of the connecting rod 661 is inserted into the rod engaging hole 663 to support the connecting rod 661 so that it can slide and swing.

  The component coupling mechanism 66b includes a coupling rod 662 and a spherical roller bearing member 666. One end of the connecting rod 662 is swingably connected to a predetermined position of the upper arm 62 b of the mountain folding mechanism 60. For example, a rod receiving portion 67b having a flat cylindrical hole 668 shown in FIG. 4 is attached to a predetermined position on the right side wall of the upper arm 62b. The flat cylindrical hole portion 668 is opened toward the lower side of the rod receiving portion 67b. One end of the connecting rod 662 is inserted into the flat cylindrical hole 668 of the rod receiving portion 67b, and the end of the connecting rod 662 is swingably connected by the rod engaging pin 68b. The rod engaging pin 68b is attached from the direction perpendicular to the flat cylindrical hole 668 outside the upper arm 62b.

  The spherical roller bearing member 666 has a rod engagement hole 664 and is provided at a predetermined position on the outer wall of the lower arm 72 b of the valley folding mechanism 70. For example, a spherical roller bearing member 666 fitted with a spherical bearing having a rod engagement hole 664 is attached to a predetermined position on the outer wall of the lower arm 72b. The other end side of the connecting rod 662 is inserted into the rod engaging hole 664, and the connecting rod 662 is slidably supported. Spherical bearings are used for the spherical roller bearing members 665 and 666.

  Accordingly, the left upper arm 62a and lower arm 72a shown in FIG. 6 are slidably and swingably connected by the component connecting mechanism 66a. Further, the upper arm 62b and the lower arm 72b on the right side are slidably and swingably coupled by the component coupling mechanism 66b.

  By this component coupling mechanism 66 (66a, 66b), the left upper arm 62a and the lower arm 72a are integrated, and the right upper arm 62b and the lower arm 72b are also integrated, so that the upper arm 62a and the lower arm 72a Are synchronized, and the upper arm 62b and the lower arm 72b operate in synchronization with each other. A simple cylindrical hole may be used for connecting the connecting rod 661 and the lower arm 72a, or connecting the connecting rod 662 and the lower arm 72b, using a spherical bearing as the rotating shaft of the upper arms 62a and 62b. This also makes it possible to provide a component connecting mechanism.

  7A to 7C are process diagrams illustrating an example of the function of the bag mouth fan folding tag binding device 100. The package 1 shown in FIG. 7A is a bag applied by the bag mouth fan folding tag binding device 100. Normally, the package 1 stores food, other products, and the like. In the drawing, foods and the like in the package 1 are omitted. The package 1 has a width of W [mm] and a length of about L [mm]. For example, the bag has a width of W = 100 mm to 250 mm and a length of L = 150 mm to 200 mm.

  The portions indicated by the broken lines in the upper and lower horizontal directions shown in FIG. 7A are bag closing allowances, which are portions that are sealed when food or the like is stored in the bag body. The sealed portion is tightly bound by thermocompression bonding or the like so that the contents do not protrude. Further, the broken line in the vertical direction is the center line c of the bag. In addition, the part from the upper part of the package 1 in the figure to length 1 comprises the to-be-folded surface II in the past, and is an area | region where a bag mouth is fold-folded.

  Next, the package 1 shown in FIG. 7B is provided with a plurality of creases from the virtual origin p to a line segment (dashed line R) forming an upper chordal arc shape. The virtual origin p is set substantially on the center line c of the package 1. The broken line R forms, for example, a part of a circular arc having a radius r from the virtual origin p. In this example, an upper frame 11a, 11b having a mountain folding mechanism 60 developed in a fan shape between the upper arms 62a, 62b and a valley folding mechanism 70 developed in a fan shape between the lower arms 72a, 72b are provided. The upper belt 63 and the lower belt 73 are substantially meshed with each other by sandwiching the folded surface II ′, which is an upper region in the figure than the broken line R of the packaging body 1, with the lower frames 21 a and 21 b, thereby virtually A plurality of creases are provided from the origin p to a broken line R having an arc shape.

  Thereafter, the packaging body 1 provided with a plurality of creases is formed in the bag mouth toward the binding part q on the substantially center line c of the packaging body 1 along the arc of the broken line R as indicated by the white arrow shown in FIG. 7C. It is made to fold (fold). As a result, the folded surface II 'of the package 1 released from the upper frames 11a and 11b and the lower frames 21a and 21b can be automatically developed into a fan shape having the binding portion q as a main part.

  Here, with reference to FIG. 8A-C, the bag mouth fan folding principle in the bag mouth fan folding tag binding apparatus 100 is demonstrated. FIG. 8A is a plan view showing an enlarged example of the package 1 shown in FIG. 7B.

  In this example, it is assumed that the bag mouth of the package 1 having the folded surface II 'is folded and automatically expanded into a fan shape. The solid line Y extending from the arc R ′ (corresponding to the broken line R in FIG. 7B) shown in FIG. 8A is, for example, a mountain fold part, and the oblique broken line Z is a valley fold part.

  In FIG. 8A, a position separated by a predetermined distance l from the substantially center upper portion of the package 1 to the center lower portion is defined as a binding site q, and an auxiliary line segment substantially perpendicular to a center line c (center vertical line segment) including the binding site q. α is defined. Folded surface II along arc R ′, which is a position higher than this auxiliary line segment α by a predetermined distance β and is a line segment that forms an arc shape from both side ends x1 and x2 of package 1 toward binding site q. 'The mountain fold and valley fold are repeated.

  FIG. 8B is a diagram illustrating an example in which a mountain fold portion and a valley fold portion adjacent to the binding site q are extracted from FIG. 8A. In this example, in order to bring the mountain fold portions x, x ′,... Points existing at a position higher than the binding site q shown in FIG. 8B to the position of the binding site q shown in FIG. Are folded while being pulled downward, and the x ′ points... Are sequentially folded while being pulled downward. There is a step of converging the bent part generated by repeating the mountain fold and the valley fold of the folded surface II 'to the binding part q shown in FIG. 8C.

  In this example, when converging both side ends x1, x2 of the package 1 to the binding part q, the bag mouth fan folding tag binding device 100 keeps the upper frames 11a, 11b and the lower frames 21a, 21b closed, Shrinking operation of the upper arms 62a, 62b having the mountain folding mechanism 60 developed in a fan shape, and shrinking operation of the lower arms 72a, 72b having the valley folding mechanism 70 deployed in a fan shape in synchronization with this. It is realized with.

  Thereby, along the line segment (dashed line R) which forms the upper chord-shaped arc shape from each of the both ends x1, x2 of the package 1 toward the binding site q, that is, the folded surface II ′. Mountain folds and valley folds are repeated (pouch mouth fan folding principle). According to such a bag mouth fan folding principle, with respect to a vertical line segment (distance) from the upper end of the bag mouth to the arc-shaped line segment converged from the both side ends x1, x2 to the binding site q The center part of 1 is long, and the side of the both end parts of the package 1 can be made shorter than that.

  Thus, according to the bag mouth fan folding tag binding device 100, when the bag mouth of the package 1 having the folded surface II ′ is folded and expanded into a fan shape, the mountain fold portion x becomes the binding site q. When converged, the distance from the top end of the bag mouth to the arc-shaped line segment on the side of the both ends of the package 1 rather than the central portion of the package 1 Therefore, a force that draws from both side ends x1, x2 to the binding site q acts. For this reason, the force which expands from the center upper part of the package 1 to both side edge part works, and the fan mouth which makes the binding part q the principal part is the binding part q automatically without applying any external force. Can be deployed.

  FIG. 9 is a front view showing an example of binding of the tag 10 in the package 1. In this example, the tag 10 is bound to the binding site q of the package 1 shown in FIG. 8C using the twist tie 2. The tag attachment drive unit 101 conveys the tag 10 to the binding site q of the package 1 and passes the twist tie 2 through the tag hole for torsional binding. For example, the tag 10 is transported so as to rise from below the table 81 and attached to a predetermined surface of the package 1. Thereby, the tag 10 can be attached to the bag mouth of the package 1 developed in a fan shape having the binding site q as a main part.

  Then, the handling example of the bag mouth fan folding tag binding apparatus 100 is divided into a case where the content of the package 1 is low (thin) and high (thick). FIG. 10 is a side view illustrating a configuration example (side surface) of the bag mouth fan folding tag binding device 100. 10, when the packaging body 1 is inserted into the bag mouth fan forming drive unit 40 with the packaging body 1 in the front-down state, the contents roll down, so that the installation surface of the bag mouth fan folding tag binding device 100 is installed. On the other hand, the entire device is inclined by an inclination angle θ1. In this example, the inclination angle θ1 is 35 °.

  The bag mouth fan folding tag bundling device 100 shown in FIG. 10 is a portion through which the bag insertion direction I of the bag mouth fan forming drive unit 40 can be seen, and a table 81 as a mounting member is provided above the tag mounting drive unit 101. It is done. In this example, in order to cope with a case where the contents of the package 1 are high (thick), the table 81 is provided with a set of mounting tables 81a and 81b as auxiliary tables. One of the mounting tables 81 a and 81 b has an inclined shape, and the other has a rectangular shape, and can be attached to and detached from the table 81. The mounting tables 81a and 81b have inclined surfaces that maintain the packaging body 1 in a posture substantially parallel to the installation surface of the bag mouth fan folding tag binding device 100 (see FIG. 16).

  For the mounting tables 81a, 81b, etc., a rubber member having the shape described above is used as an example. Since the mounting mechanisms 81a and 81b are provided with the shutter mechanism 89 in the tag mounting drive unit 101, the mounting tables 81a and 81b may be disposed at positions away from the shutter mechanism 89 and on both sides when the bag insertion opening is viewed from the bag insertion direction I. The shutter mechanism 89 has a shutter plate (not shown), and opens and closes an opening portion that the tag transport mechanism 4 shown in FIG. 47 looks into. As a result, the tag 10 can be extracted from the opening portion, and the opening portion can be covered so that unnecessary objects do not enter the inside of the machine.

  In the case of adopting the detaching method to cope with the thickness of the bag, for example, four holes are opened at predetermined intervals (not shown) on the table 81. On the other hand, convex projections are provided at the four corners at the same interval on the back surface of the mounting table 81a. The mounting table 81a and the like may be fixed to the table 81 by fitting the four protrusions of the mounting table 81a into the four holes of the table 81 described above.

  Further, when adopting the slide method to cope with the width of the bag, for example, a set of long hole portions is opened in a predetermined position (not shown) on the table 81. On the other hand, two convex protrusions (not shown) are provided on the back surface of the mounting table 81a with a predetermined interval. The mounting table 81a and the like may be slidably fixed to the table 81 by fitting the protruding portion of the mounting table 81a into the long hole portion of the table 81 described above.

  In this case, when the bag mouth of the packaging body 1 is inserted obliquely with respect to the bag insertion direction I of the bag mouth fan drive unit 40 and the packaging body 1 is placed on the inclined surfaces of the placement tables 81a and 81b, The part containing the contents of the package 1 can be maintained in a posture substantially parallel to the installation surface of the apparatus 100.

[When the content of the package 1 is low (thin)]
FIG. 11 is an explanatory view showing an example (part 1) of attaching the bag mouth fan folding tag in the package 1, and viewing the mountain folding mechanism 60 and the valley folding mechanism 70 of the bag mouth fan folding tag binding device 100 from the lateral direction. FIG. When the height h of the contents of the package 1 shown in FIG. 11 is low, the bag mouth fan folding and tag attachment are performed in a state where the valley folding mechanism 70 and the table 81 are aligned. Here, the height h of the contents of the package 1 refers to the length from the reference surface to the highest part of the package 1 when the package 1 is placed on the reference surface. The state where the valley folding mechanism 70 and the table 81 are aligned is a case where the height of the lower belt 73 (bellows) of the valley folding mechanism 70 is the same as the height of the table. When the height of the contents of the package 1 is low (thin), the entire apparatus is tilted by the inclination angle θ1, so that the contents do not gather near the front portion of the package 1, and the tag 10 Can be attached.

  FIG. 12 is an explanatory view showing a bag mouth fan folding tag attachment example (part 2) in the package 1. According to the bag mouth fan folding tag attachment example shown in FIG. 12, the package body 1 having a low (thin) content is set in the valley fold mechanism 70 of the bag mouth fan drive unit 40 (bag set). is there. According to this state, the folded surface II ′ of the package 1 is placed so as to contact the lower band 73 (bellows) of the valley folding mechanism 70.

  FIG. 13 is an explanatory view showing a bag mouth fan folding tag attachment example (No. 3) in the package 1. According to the bag mouth fan folding tag attachment example shown in FIG. 13, the tag 10 is bound to the packaging body 1 whose content is low (thin) and twisted with the twist tie 2. The bundling of the tag 10 and the twisting process of the twist tie 2 are performed after the mountain folding mechanism 60 and the valley folding mechanism 70 complete the contraction operation.

  For example, the tag attachment drive unit 101 binds the tag 10 to the binding portion q of the bag mouth of the package 1 that is focused by the mountain fold mechanism 60 and the valley fold mechanism 70. In this example, in order to attach the tag 10 to the center position on the surface of the package body 1, the bellows center position, the twist position of the twist tie 2, the transport position of the tag 10, , Four of the tagging surfaces are arranged in a straight line in the vertical direction. The tagging surface is set on the table 81.

  That is, with respect to the tagging surface of the package 1, the tag 10 moves in a planar state from the direction of the white arrow in the figure (downward side) to the table 81 side (upper side). If comprised in this way, the bag mouth of the package 1 which accommodated foodstuffs, other goods, etc. will be folded, the tag 10 will be automatically attached to the binding part q, and the bag mouth will be fan-shaped around the tag attachment part. It becomes possible to provide the bag mouth fan folding tag binding device 100 to be developed.

[When the content of the package 1 'is high (thick)]
FIGS. 14 and 15 are explanatory views showing examples (parts 1 and 2) of attaching the bag mouth fan folding tag in the package 1 ′, and the mountain folding mechanism 60 and the valley folding mechanism 70 of the bag mouth fan folding tag binding device 100. It is the figure which looked at from the horizontal direction.

  In this example, the height h ′ of the contents of the package 1 ′ is higher (thick) than the package 1. When the height h ′ of the contents of the package 1 ′ is high, the package 1 ′ is placed on the table 81 as compared with the case where the height h of the contents of the package 1 is low, as shown in FIG. When this occurs, the folded surface II ′ of the package 1 ′ is spaced upward from the lower band 73 (bellows) of the valley fold mechanism 70. Therefore, in order to approximate the ideal state where the valley folding mechanism 70 and the table 81 are aligned in a case where the height h of the contents of the package 1 is low, as shown in FIG. The folding surface II ′ is folded and loaded into the bag insertion port from the bag insertion direction I.

  In this operation, since the entire apparatus is inclined by the inclination angle θ1, the contents do not gather near the front portion of the package 1 ′, but the operator can insert the bag mouth fan and attach the tag. Until the process is finished, the packaging body 1 ′ that is lifted upward from the table 81 must be held in the hand. Therefore, when the height h ′ of the contents of the package 1 ′ is high, the table 81 is provided with a pair of detachable and movable mounting tables 81 a and 81 b as shown in FIG. 1.

  16A and 16B are explanatory views showing an example of placing the package 1 'when the bag mouth fan folding tag is attached. The mounting table 81a and the like shown in FIG. 16A are provided with a first inclined surface IIIa for mounting the folding surface and a second inclined surface IIIb for mounting the packaging body excluding the folding surface II '. The first inclined surface IIIa is set to form a state in which the valley folding mechanism 70 and the table 81 are aligned.

  The second inclined surface IIIb is set to protect the contents and improve workability. In this example, when the angle formed between the second inclined surface IIIb and the first inclined surface IIIa is the inclination angle θ2, and the lowering angle of the bag rear end is the inclination angle Δθ, the angle between the inclination angles θ2, θ1, and Δθ. Is set to θ2 = θ1−Δθ. That is, the second inclined surface IIIb is inclined toward the tag attachment drive unit 101 by an inclination angle Δθ from a reference surface parallel to the installation surface of the bag mouth fan folding tag binding device 100. Due to this inclination, the bag rear end portion is placed lower than the reference surface (ground surface).

  The inclination angle θ2 is an angle constituted by the height h ′ of the package 1 ′ and the length from the contents to the binding site q. The inclination angle θ2 is about 10 ° to 60 °. This inclination angle θ2 may be variable or fixed depending on the height h ′ of the package 1 ′. When the above-described angle Δθ is set, even when the bag mouth fan folding and tag attachment processing is performed on the package 1 ′ having a high content height h ′, the content is directed obliquely downward and the content is the bag. The force pressed against the insertion opening is eliminated.

  As a result, when the bag mouth fan folding tag binding device 100 is operated in the positional relationship shown in FIG. 16A, the rear end of the package 1 ′ does not rise during the contraction operation of the mountain fold mechanism 60 and the valley fold mechanism 70. The bag mouth fan folding and tag attachment processing can be performed with the contents brought close to the rear end side of the package 1 ′ and lightly pressed by hand. Therefore, contents such as rice crackers and cookies can be maintained at predetermined positions inside the package 1 '.

  FIG. 16B shows a package 1 ′ having a high content height h ′, and the package 1 ′ has a bag angle θ <b> 3. Here, the bag angle θ3 is an extension line la of the folding surface II ′ of the packaging body 1 ′ when the extension line of the folding surface II ′ of the packaging body 1 ′ is la and the spread line is lb. It is an angle between the expanded line lb. It is preferable to set a relation of θ2 <θ3 between the inclination angle θ2 and the bag angle θ3. This is because when the inclination angle is set to θ2 <θ3, when the packaging body 1 ′ having a high content height h ′ is placed on the second inclined surface IIIb, the rear end side of the packaging body 1 ′ is always lowered. Can be maintained.

  As described above, when the tilt angle Δθ is set with respect to the tilt angle θ1 of the process base 102, when the contents of the package 1 ′ have a predetermined height h ′, the contents of the package 1 Forming the bag mouth of the packaging body 1 'into a fan shape with good reproducibility in a state of being close to the rear end side of the packaging body 1' without concentrating near the bag mouth of the packaging body 1 ' The tag 10 can be attached to the bag mouth with good reproducibility.

  FIG. 17 is an explanatory diagram showing a modification of the mounting tables 81a and 81b. According to the mounting tables 81a and 81b shown in FIG. 17, the bag stopper 81c constituting an example of the receiving member is provided at the rear end portion of the second inclined surface IIIb. The bag stopper 81c defines the rear end of the bag and is attached so as to bridge the mounting tables 81a and 81b. The bag stopper 81c receives the package 1 'placed on the placing tables 81a and 81b and having a predetermined height h'. A resin plate, an aluminum plate, or the like is used for the bag stopper 81c.

  When the bag stopper 81c is attached to the rear end portion of the second inclined surface IIIb as described above, even if the contents of the package 1 ′ have a predetermined height h ′, the contents However, the bag mouth of the packaging body 1 'is formed into a fan shape with good reproducibility in a state where it is brought close to the rear end side of the packaging body 1' without being concentrated near the bag mouth of the packaging body 1 '. can do.

  Moreover, even when the bag mouths of the plurality of packaging bodies 1 ′ are continuously formed into a fan shape and the tag 10 is continuously attached, the fan mouth shape of the bag mouth of the packaging body 1 ′ can be made uniform, so the reproducibility is good. And tag 10 can be attached uniformly. For example, the tagged package 1 having the same bag mouth fan shape can be produced at a rate of 8 to 10 per minute.

  As described above, according to the bag mouth fan folding tag binding device 100 according to the present invention, the process base 102 having the predetermined inclination angle θ1 with respect to the installation surface of the device includes the bag mouth fan forming drive unit 40 and the tag mounting drive. The joint processing unit 104 having the unit 101 is supported obliquely. At this time, the bag mouth of the package 1 inserted at an angle is positioned above the joint processing unit 104 provided with the bag mouth fan forming drive unit 40, and its contents are obliquely below the joint processing unit 104. Come to face.

  Accordingly, the packaging body 1 is inserted obliquely with respect to the bag insertion direction I of the bag mouth fan drive unit 40, and the packaging body 1 is maintained in a posture substantially parallel to the apparatus installation surface. The bag mouth can be folded into a bellows shape and the bag mouth can be formed into a fan shape, and the tag 10 can be attached to the bag mouth of the package 1. In particular, even when the contents of the package 1 ′ have a predetermined height h ′, the contents of the package 1 are moved to the rear end side of the package 1 ′. The bag mouth can be formed into a fan shape with good reproducibility, and the tag 10 can be attached to the bag mouth of the package 1 with good reproducibility. Thereby, it becomes possible to provide the package 1 in which the tag 10 is attached to the fan-shaped bag mouth developed with the binding site q as a main part.

  FIG. 18 is a perspective view showing an arrangement example of the component coupling mechanisms 66 (66 a, 66 b) in the bag mouth fan forming drive unit 40 of the bag mouth fan folding tag binding device 100. FIG. 19 is a left side view illustrating an operation example of the bag mouth fan forming drive unit 40 when the frame is expanded. FIG. 20 is a left side view showing an operation example when the crank driving mechanism 41 is contracted and closed.

  18 is provided with a component connection mechanism 66 (66a, 66b). The bag mouth fan drive unit 40 drives the mountain fold mechanism 60 and the valley fold mechanism 70 by interlocking the upper arms 62a and 62b (first component) and the lower arms 72a and 72b (second component). The upper arms 62a and 62b and the lower arms 72a and 72b are driven by crank drive mechanisms 42a and 42b.

  One end of each of the upper arms 62a and 62b is slidably engaged with the upper guide rails 61a and 61b, and the other end of the upper arm 62a and 62b rotates on the support shaft 18a of the rotary bearing portion 13a provided on each rotary shaft portion of the upper reinforcing member 12b. The bearings 13b are respectively supported on the support shafts 18b. For example, according to the operation example when the upper frame is expanded in the bag mouth fan forming drive unit 40 shown in FIG. 19, the crank drive mechanism 41 is driven by the rotation of the vertical motor 58a shown in FIG. The gear 54a and the crank arm 54b are driven, and the upper frames 11a and 11b are expanded upward using the support shafts 23a and 23b as rotation axes.

  Here, the home positions HP of the upper frames 11a and 11b are set. Here, the home position HP of the upper frames 11a and 11b is a position at the time of maximum frame expansion where the upper frames 11a and 11b are most widely opened. The home positions HP of the upper frames 11a and 11b are determined by the position at which the crank arm 54b with respect to the crank gear 54a stops at the top dead center Pu (see FIG. 22).

  Further, the crank drive mechanism 41 contracts the upper frames 11a and 11b downward from the home position HP shown in FIG. 19 as shown in FIG. According to the operation example of the crank drive mechanism 41 when the upper frame is contracted and closed, the vertical motor 58a shown in FIG. 18 rotates in one direction to drive the motor gear 54d, the crank gear 54a, and the crank arm 54b, The upper frames 11a and 11b are closed downward using the support shafts 23a and 23b as rotation axes and stopped at the frame contracted position. The frame contracted position is a position where the crank arm 54b with respect to the crank gear 54a moves at the bottom dead center Pd by moving from the home position HP of the upper frames 11a and 11b.

  The lower arms 72a and 72b shown in FIG. 18 have one end slidably engaged with the lower guide rails 71a and 71b and the other end rotatable with respect to rotary bearing portions 77a and 77b provided on the lower reinforcing member 22b. Supported and interlocked with the upper arms 62a and 62b. The lower reinforcing member 22b is attached and fixed to the lower frames 21a and 21b.

  In this example, a twisting phenomenon occurs in the upper arms 62a and 62b and the lower arms 72a and 72b due to the vertical opening / closing operation of the upper frames 11a and 11b with respect to the lower frames 21a and 21b shown in FIGS. The upper arms 62a and 62b with such a twisting phenomenon must be reliably interlocked. A description will be given with reference to a simplified model of a phenomenon in which the second rotating shaft is twisted with respect to the first rotating shaft between the two components (hereinafter referred to as a twisting phenomenon).

  21A and 21B are perspective views of a simplified model showing an example of a twist phenomenon between the upper arms 62a and 62b and the lower arms 72a and 72b. According to the simplified model shown in FIG. 21A, the first rotating shaft 01 corresponds to the rotating bearing portions 13a and 13b and is the center of rotation of the upper arms 62a and 62b. Here, when p0 in the figure is the arm reference position of the upper arms 62a and 62b, p1 indicates a position rotated 45 ° clockwise from the arm reference position p0 with respect to the rotation axis 01. p2 indicates a position rotated 90 ° clockwise from the arm reference position p0 with respect to the rotation axis 01.

  Similarly, p1 'indicates a position rotated 45 ° counterclockwise from the arm reference position p0 with reference to the rotation axis 01. p2 'indicates a position rotated 90 ° counterclockwise from the arm reference position p0 with reference to the rotation axis 01. Note that the second rotation shaft 02 is a portion where the support shafts 23a and 23b for the fulcrum shaft are arranged, and is the center of rotation of the upper frames 11a and 11b with respect to the lower frames 21a and 21b.

  FIG. 21B shows a model in which the simplified model of the upper arms 62 a and 62 b and the simplified model of the lower arms 72 a and 72 b are connected by one rotating shaft 02. The rotation centers of the lower arms 72 a and 72 b exist on a plane different from that of the first rotation axis 01. According to the connected model shown in FIG. 21B, the planes where the upper arms 62a and 62b exist at the arm reference position p0 and the plane where the lower arms 72a and 72b exist are not accompanied by a twist phenomenon, and the two arm surfaces are It exists on the same plane. However, at positions p1 and p1 ′ rotated 45 ° from the arm reference position p0 with respect to the rotation axis 01, the plane in which the upper arms 62a and 62b exist and the plane in which the lower arms 72a and 72b exist are twisted. Therefore, the two arm surfaces do not exist on the same plane and are in a twisted relationship.

  As described above, in the bag mouth fan drive unit 40, the upper arms 62a and 62b and the lower arms 72a and 72b exist in the same plane in a series of operations, and are in a twisted relationship. Can take. Therefore, in any state, a connection method is required so that the upper arms 62a and 62b and the lower arms 72a and 72b can be interlocked to perform the contracting and expanding operations smoothly.

  In this example, the component coupling mechanism 66a is disposed between the upper arm 62a and the lower arm 72a, and the component coupling mechanism 66b is disposed between the upper arm 62b and the lower arm 72b to allow for a twist. Provided is a three-dimensional connection structure between parts rotating around two axes. In this example, a spherical roller bearing member 665 is attached to the lower arm 72a, and a spherical roller bearing member 666 is attached to the lower arm 72b. Of course, the spherical roller bearing member 665 may be attached to the upper arm 62a side, and the spherical roller bearing member 666 may be attached to the upper arm 62b side.

  Spherical bearings are used for the spherical roller bearing members 665 and 666. The spherical bearing operates to absorb the twist between the upper arms 62a and 62b and the lower arms 72a and 72b. If the component connection mechanism 66 (66a, 66b) is configured in this way, the upper arms 62a, 62b and the lower arms 72a, 72b can be reliably interlocked (first connection method).

  Subsequently, an operation example of the component coupling mechanism 66 (66a, 66b) in the bag mouth fan forming drive unit 40 will be described with reference to FIGS. 22 and 25 to 29, the mountain folding mechanism 60 and the valley folding mechanism 70 are omitted. FIG. 22 is a perspective view showing a state example of the component coupling mechanism 66 (66a, 66b) of the bag mouth fan forming drive unit 40 at the home position.

  According to the component connection mechanism 66 (66a, 66b) of the bag mouth fan forming drive unit 40 shown in FIG. 22, the left and right connection rods 661, 662 are long exposed upward from the respective spherical roller bearing members 665, 666. It is in a state. This state is a case where the upper frames 11a and 11b stay at the home position HP.

  In this example, the crank drive mechanism 41 drives the motor gear 54d, the crank gear 54a, and the crank arm 54b by rotating a vertical motor 58a (not shown), and the upper frames 11a, 11b using the support shafts 23a, 23b as rotation axes. Open and close up and down. According to the home positions of the upper frames 11a and 11b described above, the crank arm 54b relative to the crank gear 54a is a position where the crank arm 54b stops at the top dead center Pu.

  FIG. 23 is a top view showing an example of the state of the bag mouth fan forming drive unit 40 at the home position HP. In the bag mouth fan forming drive unit 40 shown in FIG. 23, the home positions of the upper arm 62a and the lower arm 72a are located at the positions where the upper arm 62a for the left fan and the lower arm 72a for the left fan are most opened. Ha is set. Similarly, the home position Hb of the upper arm 62b and the lower arm 72b is set at a position at which the upper arm for the right fan and the lower arm 72b for the right fan are most opened.

  In this example, the crank drive mechanism 42a for the left fan drives the motor gear 55c, the crank gear 55a, and the crank arm 56a by rotating a fan left motor 59a (not shown), and a rotating shaft portion 77a (not shown) of the lower arm 72a. The lower arm 72a is expanded and contracted using the rotation axis. In conjunction with this, the upper arm 62a coupled by the component coupling mechanism 66a is expanded and contracted with the rotation bearing portion 13a as the rotation axis.

  According to the home position Ha of the upper arm 62a and the lower arm 72a, the crank arm 56a with respect to the crank gear 55a is a position where the crank arm 56a stops at the bottom dead center Ld. The crank driving mechanism 42a rotates the left fan crank gear 55a counterclockwise to shift to the top dead center Lu (see FIG. 27).

  According to the crank drive mechanism 42b for the right fan shown in FIG. 23, when the fan right motor 59b (not shown) rotates, the motor gear 55d, the crank gear 55b, and the crank arm 56b are driven, and the rotary shaft portion 77b is used as the rotary shaft. The lower arm 72b is expanded and contracted.

  In conjunction with this, the upper arm 62b coupled by the component coupling mechanism 66b is expanded and contracted with the rotation bearing portion 13b as the rotation axis. According to the above-described home positions Hb of the upper arm 62b and the lower arm 72b, the crank arm 56b with respect to the crank gear 55b is a position where the crank arm 56b stops at the bottom dead center Rd. Further, the crank drive mechanism 42b rotates the right fan crank gear 55b counterclockwise to shift to the top dead center Ru (see FIG. 27).

  Such a state in which the upper frames 11a and 11b are expanded and the upper arms 62a and 62b are also expanded will be referred to as a state example when the frame is opened and the arms are opened. FIG. 24 is a perspective view of a state example of the component coupling mechanism 66 (66a, 66b) when the frame is opened and the arm is opened as seen from another angle. According to the bag mouth fan forming drive unit 40 shown in FIG. 24, the mountain fold mechanism 60 and the valley fold mechanism 70 are mounted.

  In the bag mouth fan forming drive unit 40, when the crank drive mechanisms 42a and 42b are operated, the rotating shaft portions 77a of the lower arm 72a and the rotating shaft portions of the lower arm 72b are operated by the component connecting mechanisms 66 (66a and 66b). 77b is set as the rotation axis, and the left and right upper and lower arms 62a and 72a and the right and left upper and lower arms 62b and 72b are synchronized with each other. The contraction operation can be performed.

  25 is an enlarged perspective view showing an example of the state of the component coupling mechanism 66b in the bag mouth fan forming drive unit 40, and is an enlarged view of the state in which the upper frame 11b is separated from the bag mouth fan forming drive unit 40 shown in FIG. It is. According to the component connection mechanism 66b when the frame is opened and the arm is opened as shown in FIG. 25, the upper frame 11b, the upper arm 62b, and the lower arm 72b are desired to be opened. That is, the upper arm 62b and the lower arm 72b are both in a torsional positional relationship that does not exist on the same plane, and the component coupling mechanism 66b is operatively coupled while allowing displacement due to torsion (posture). ).

  FIG. 26 is a perspective view showing an example of a state of the component coupling mechanism 66 (66a, 66b) in the bag mouth fan forming drive unit 40 when the frame is closed and the arm is opened. According to the component connecting mechanism 66 (66a, 66b) of the bag mouth fan forming drive unit 40 shown in FIG. 26, the left and right connecting rods 661, 662 are respectively spherical roller bearing members as shown in FIGS. It is in a state where it is long exposed downward from 665,666. In this state, the contracted positions of the upper frames 11a and 11b are set. Here, the contracted position of the upper frames 11a and 11b refers to the position when the frame contraction is completed. The upper arms 62a and 62b and the lower arms 72a and 72b remain at the home positions Ha and Hb.

  In this example, the crank drive mechanism 41 drives the motor gear 54d, the crank gear 54a, and the crank arm 54b by rotating the vertical motor 58a shown in FIG. 18 in one direction from the home position HP shown in FIG. Then, the upper frames 11a and 11b are closed downward with the support shafts 23a and 23b as the rotation axes. From the home position HP of the above-described upper frames 11a and 11b, the crank arm 54b with respect to the crank gear 54a is a position at which it stops at the bottom dead center Pd.

  According to the operation example when the frame is closed and the arm is opened, the left fan crank drive mechanism 42a and the right fan crank drive mechanism 42b are stationary only by the upper frames 11a and 11b being contracted and closed. That is, the upper arms 62a and 62b and the lower arms 72a and 72b are in the state of being located at the home positions Ha and Hb. In this state, since the upper frames 11a and 11b are contracted, there is no twisted positional relationship between the upper arm 62a and the lower arm 72a, and the upper frames 11a and 11b exist in the same plane, and There is no twisted positional relationship between the upper arm 62b and the lower arm 72b, and the upper arm 62b and the lower arm 72b are in the same plane. In this state, no displacement caused by torsion occurs, so that the component coupling mechanism 66 (66a, 66b) does not have to allow displacement caused by torsion.

  FIG. 27 is a perspective view showing an example of a state of the component coupling mechanism 66 (66a, 66b) in the bag mouth fan forming drive unit 40 when the frame is closed and the arm is closed. According to the operation example of the part connecting mechanism 66 (66a, 66b) of the bag mouth fan forming drive unit 40 shown in FIG. 27 when the frame is closed and the arm is closed, the left and right upper arms 62a, 62b and the left and right lower arms 72a, 72b. The crank drive mechanism 41 is stationary only by performing the contracting and closing operation. Accordingly, the posture of the component connecting mechanism 66 (66a, 66b) when the frame is closed and the arm is closed is the same as the posture of the component connecting mechanism 66 (66a, 66b) when the frame is closed and the arm is opened.

  In this example, the crank drive mechanism 42a for the left fan shown in FIG. 27 has a motor gear 55c, a crank, and the like when the fan left motor 59a rotates at the home position Ha of the upper arm 62a and the lower arm 72a shown in FIG. The gear 55a and the crank arm 56a are driven, and the lower arm 72a is contracted and closed with the rotating shaft 77a of the lower arm 72a as the rotating shaft. In conjunction with this, the upper arm 62a operatively coupled by the component coupling mechanism 66a is contracted and operated with the rotation bearing portion 13a as the rotation axis. With this operation, the crank arm 56a with respect to the crank gear 55a moves from the bottom dead center Ld to the top dead center Lu and stops.

  In addition, the crank drive mechanism 42b for the right fan shown in FIG. 27 is such that the right motor 59b shown in FIG. 18 rotates at the home position Hb of the upper arm 62b and the lower arm 72b shown in FIG. 55d, the crank gear 55b and the crank arm 56b are driven, and the lower arm 72b is contracted and closed with the rotating shaft 77b as the rotating shaft. In conjunction with this, the upper arm 62b operatively connected by the component connecting mechanism 66b is contracted and operated with the rotating bearing portion 13b as the rotating shaft. With this operation, the crank arm 56b with respect to the crank gear 55b moves from the bottom dead center Rd to the top dead center Ru and stops.

  Thus, according to the operation example when the frame is closed and the arm is closed, the upper arms 62a and 62b and the lower arms 72a and 72b are only contracted and closed, and the crank driving mechanism 41 is stationary. That is, the upper arms 62a and 62b and the lower arms 72a and 72b at the home positions Ha and Hb shown in FIG. 26 operate independently from each other toward the center. During this left and right independent operation, the upper arm 62a and the lower arm 72a are not in a torsional positional relationship and are in the same plane, and between the upper arm 62b and the lower arm 72b. There is no twisted positional relationship, and there is a state that exists in the same plane. In this state, no displacement due to torsion occurs, so that the component coupling mechanism 66 (66a, 66b) does not have to allow displacement due to torsion. In this example, the upper and lower arms 62a and 62b and the lower arms 72a and 72b are contracted to converge the mountain folding mechanism 60 and the valley folding mechanism 70. Note that the rotation direction of the fan left motor 59a, the fan right motor 59b, and the like at this stage may be either forward rotation or reverse rotation.

  FIG. 28 is a perspective view showing an example of the state of the component connection mechanism 66 (66a, 66b) in the bag mouth fan forming drive unit 40 when the frame is closed and the arm is opened. According to the operation example of the part coupling mechanism 66 (66a, 66b) of the bag mouth fan forming drive unit 40 shown in FIG. 28 when the frame is closed and the arm is opened, the left and right upper arms 62a, 62b and the left and right lower arms 72a, 72b. Only expands, and the crank drive mechanism 41 is stationary. Accordingly, the posture of the component connecting mechanism 66 (66a, 66b) when the frame is closed and the arm is closed is the same as the posture of the component connecting mechanism 66 (66a, 66b) when the frame is closed and the arm is opened.

  In this example, the crank drive mechanism 42a for the left fan shown in FIG. 28 has a motor gear 55c, a crank, and the like when the fan left motor 59a rotates in the contracted position of the upper arm 62a and the lower arm 72a shown in FIG. The gear 55a and the crank arm 56a are driven, and the lower arm 72a is expanded using the rotating shaft 77a of the lower arm 72a as a rotating shaft. In conjunction with this, the upper arm 62a operatively connected by the component connecting mechanism 66a performs an expanding operation with the rotary bearing portion 13a as the rotational axis. With this operation, the crank arm 56a with respect to the crank gear 55a shifts from the top dead center Lu to the bottom dead center Ld and stops.

  Further, the right fan crank drive mechanism 42b shown in FIG. 28 has a motor gear 55d and a crank gear 55b as the fan right motor 59b rotates in the contracted position of the upper arm 62b and the lower arm 72b shown in FIG. Then, the crank arm 56b is driven, and the lower arm 72b is expanded using the rotary shaft portion 77b as the rotary shaft. In conjunction with this, the upper arm 62b operatively connected by the component connecting mechanism 66b is expanded with the rotary bearing portion 13b as the rotational axis. With this operation, the crank arm 56b with respect to the crank gear 55b moves from the top dead center Ru to the bottom dead center Rd and stops.

  As described above, according to the operation example when the frame is closed and the arm is opened, the upper arms 62a and 62b and the lower arms 72a and 72b are only expanded and the crank drive mechanism 41 is stationary. That is, the upper arms 62a and 62b and the lower arms 72a and 72b at the home positions Ha and Hb shown in FIG. 26 operate independently from the center to the left and right. During this left and right independent operation, the upper arm 62a and the lower arm 72a are not in a torsional positional relationship and are in the same plane, and between the upper arm 62b and the lower arm 72b. There is no twisted positional relationship, and there is a state that exists in the same plane. In this state, no displacement caused by torsion occurs, so that the component coupling mechanism 66 (66a, 66b) does not have to allow displacement caused by torsion. In this example, the upper arms 62a and 62b are expanded to extend the mountain folding mechanism 60 and the valley folding mechanism 70. The rotation direction of the fan left motor 59a and the fan right motor 59b at this stage may be either forward rotation or reverse rotation.

  FIG. 29 is a perspective view showing an example of a state of the component coupling mechanism 66 (66a, 66b) in the bag mouth fan forming drive unit 40 when the frame is opened and the arm is closed. According to the operation example of the part connection mechanism 66 (66a, 66b) of the bag mouth fan drive unit 40 shown in FIG. 29 when the frame is opened and the arm is closed, the upper frames 11a, 11b are only expanded and crank driven. The mechanisms 42a and 42b are stationary.

  At this time, the upper arm 62a and the lower arm 72a, and the upper arm 62b and the lower arm 72b are not in the above-described twisted positional relationship, and are in a state where they exist on the same plane. However, the upper arms 62a and 62b expand so as to draw an arcuate locus as shown by arc-shaped arrows in FIG. 29 in accordance with the expanding operation of the upper frames 11a and 11b. For this reason, in the component coupling mechanism 66 (66a, 66b), although the displacement due to the twist described above does not occur, the displacement due to the expansion so as to draw the arc-shaped locus described above occurs. At this time, the component connecting mechanism 66 (66a, 66b) operates and connects the upper arm 62a and the lower arm 72a and operates the upper arm 62b and the lower arm 72b while allowing displacement due to the arcuate locus. Link.

  In this example, the crank drive mechanism 41 drives the motor gear 54d, the crank gear 54a, and the crank arm 54b by rotating the vertical motor 58a (not shown) in the contracted and closed positions of the upper frames 11a and 11b described above, thereby supporting the spindle. The upper frames 11a and 11b are expanded upward with the rotation axes 23a and 23b (moving to the home position Hp). With this operation, the crank arm 54b with respect to the crank gear 54a moves from the bottom dead center Pd to the top dead center Pu and stops.

  As described above, according to the operation example when the frame is opened and the arm is closed, the upper frames 11a and 11b only expand and the crank drive mechanisms 42a and 42b are stationary. That is, the upper frames 11a and 11b at the contracted position shown in FIG. 27 are expanded upward. Table 1 shows the opening and closing positions of the upper frames 11a and 11b, the opening and closing positions of the upper arms 62a and 62b and the lower arms 72a and 72b, the relationship between the upper arm 62a and the lower arm 72a, the upper arm 62b and the lower arm 72b, and component connection. An example of the function of the mechanism 66 (66a, 66b) is shown.

  The component coupling mechanism 66b includes a coupling rod 662 and a spherical roller bearing member 666. One end of the connecting rod 662 is swingably connected to a predetermined position of the upper arm 62 b constituting the mountain folding mechanism 60. The other end of the connecting rod 662 is inserted into a rod engaging hole 664 of a spherical roller bearing member 666 provided at a predetermined position of the lower arm 72b constituting the valley folding mechanism 70, and supported so as to be slidable and swingable. The

  Therefore, in the guide mechanism composed of the upper guide rail 61a and the lower guide rail 71a and the guide mechanism composed of the upper guide rail 61b and the lower guide rail 71b in consideration of the twist between the mountain fold mechanism 60 and the valley fold mechanism 70, The folding mechanism 60 and the valley folding mechanism 70 can be operatively connected in a three-dimensional manner. Thereby, the mountain fold mechanism 60 and the valley fold mechanism 70 can be reliably interlocked. And the cost reduction of the bag mouth fan folding tag binding apparatus 100 by the simplification of the said bag mouth fan shaping | molding drive unit 40 can be aimed at.

  As a modification of the component coupling mechanism 66 (66a, 66b), there is a slidable guide function between the upper arm 62a and the lower arm 72a and between the upper arm 62b and the lower arm 72b. A mechanism is also conceivable in which the upper arms 62a and 62b and the lower arms 72a and 72b are interlocked with each other by arranging a pair of connection plates.

  For example, a set of connection plates is provided on the lower arms 72a and 72b. The connecting plate is fixed to both side walls of the lower arm 72a and the like so as to expand in a trumpet shape as it goes upward. The upper arm 62a and the like are slidably engaged with the portion expanded in the trumpet shape. When the upper arm 62a or the like is on the upper side, the guide is widened in consideration of “twist”. As the upper arm 62a and the like come downward, the twist decreases, so that the guide may be narrowly guided (second connecting method).

  FIG. 30 is a top view of the bag mouth fan forming drive unit 40 showing an arrangement example of the crank gear check mechanisms 57a and 57b in the crank drive mechanisms 42a and 42b. A crank gear check mechanism 57a is arranged in the crank drive mechanism 42a shown in FIG. 30, and a crank gear check mechanism 57b is arranged in the crank drive mechanism 42b. The crank gear check mechanism 57a is engaged with the crank gear 55a and operates so as to restrict the rotation direction of the crank gear 55a to one direction. For example, the crank gear check mechanism 57 a is provided with a check gear 571 that meshes with the crank gear 55 a, and the check gear 571 has a shaft portion 573. A one-way clutch is attached to the shaft portion 573. The one-way clutch is attached to the back side of the upper left chassis 36a and functions to regulate the rotation direction of the shaft portion 573 in one direction (see FIG. 32).

  Further, the crank gear check mechanism 57b is engaged with the crank gear 55b and operates so as to restrict the rotation direction of the crank gear 55b to one direction. For example, the crank gear check mechanism 57b is provided with a check gear 572 that meshes with the crank gear 55b, and the check gear 572 has a shaft portion 573. A one-way clutch is attached to the shaft portion 573. The one-way clutch is attached to the back side of the upper right chassis 37a and functions to regulate the rotation direction of the shaft portion 573 in one direction (see FIG. 32).

  Thus, when the crank gear check mechanism 57a is arranged in the crank drive mechanism 42a and the crank gear check mechanism 57b is arranged in the crank drive mechanism 42b, the rotation direction of the crank gear 55a meshed with the check gear 571 is set to one. The direction of rotation of the crank gear 55b meshed with the check gear 572 can be restricted to one direction. Therefore, the mountain folding mechanism 60 and the valley folding mechanism 70 can be prevented from returning in the expanding direction.

  FIG. 31 is a top view of the crank drive mechanism 42a showing a setting example of the bottom dead center Ld of the crank arm 56a, and is an enlarged view showing a configuration example of the crank drive mechanism 42a shown in FIG. The bottom dead center Ld of the crank arm 56a of the crank drive mechanism 42a shown in FIG. 31 is set to the home position Ha of the upper arm 62a and the lower arm 72a. When the crank arm 56a with respect to the crank gear 55a sets the bottom dead center Ld to the home position Ha, the upper arm 62a and the lower arm are located at the home position Ha when the left arm upper arm 62a and the lower arm 72a are fully opened. The arm 72a can be stationary.

  When the crank gear 55a is rotated from the home position Ha in the rotation direction Ia (counterclockwise) in the drawing, the crank arm 56a shifts from the bottom dead center Ld to the top dead center Lu (see FIG. 34). The rotation direction Ia in the figure is the counterclockwise direction, while Ib indicates the rotation direction (clockwise direction) of the check gear 571.

  In this example, the bottom dead center Ld reaches the top dead center Lu, the rotation angle of the crank gear 55a is set from the angle 0 ° to the angle 160 °, the top dead center Lu reaches the bottom dead center Ld, and similarly the angle The angle is set from 160 ° to 360 °. The same applies to the crank arm 56b.

  FIG. 32 is a cross-sectional view showing a configuration example of the crank gear check mechanism 57a. FIG. 33 is a perspective view showing an attachment example of the crank gear check mechanism 57a. 32 includes a check gear 571, a shaft portion 573, a one-way clutch 574, an upper bearing 575, a lower bearing 576, a check holder 577 (made of aluminum), and two C-type retaining rings. 578.

  The shaft portion 573 is inserted into the one-way clutch 574, and a lower bearing 576 is fixed to the lower portion of the shaft portion 573 and incorporated in the check holder 577. The lower bearing 576 is stopped by a first retaining ring 578 so as not to come out from the back surface of the check holder 577. The assembly intermediate in which the one-way clutch 574 and the lower bearing 576 are incorporated in the check holder 577 is attached so that the upper part of the shaft part 573 is inserted into a predetermined hole from the back side of the upper left chassis 36a shown in FIG. . For example, the check holder 577 is fixed via a predetermined screw 579 from the surface side of the upper left chassis 36a.

  Further, the upper bearing 575 is inserted and attached to the shaft portion 573 protruding to the surface side of the left upper chassis 36a. The upper bearing 575 is stopped by a second retaining ring 578 so as not to come out of the surface of the upper left chassis 36a. Thereafter, a check gear 571 is attached and fixed to the upper portion of the shaft portion 573. The check gear 571 is meshed with the crank gear 55a. Thereby, the crank gear check mechanism 57a is completed. The crank gear check mechanism 57b is similarly assembled and attached to the upper right chassis 37a.

  In the crank gear check mechanisms 57a and 57b, the rotation direction of the crank gears 55a and 55b is restricted to one direction. When the crank gear check mechanism 57a as shown in FIG. 32 is engaged with the crank gear 55a, the one-way clutch 574 has a structure that rotates only in one direction, so the motor gear 55c and the crank gear 55a also rotate only in one direction. become unable.

  In this example, the check gear 571 is always idling in normal times. When the crank angle of the crank arm 56a is adjusted, a resistance force is applied in the opposite direction to the idling direction of the check gear 571 when the packaging body 1 is focused. Thus, it is possible to prevent the mountain folding mechanism 60 and the valley folding mechanism 70 from opening during the arm contracting operation.

  FIG. 34 is a top view showing an example of setting the top dead center Lu of the crank arm 56a. The top dead center Lu of the crank arm 56a shown in FIG. 34 is obtained when the rotation shaft 552 and the crank shaft 551 of the crank gear 55a and the shaft center of the crank arm 56a are connected on one straight line and the locus of the crank shaft 551. The top dead center Lu is taken at the point where the crosses. At this time, since the crank drive mechanism 42a is rigid, the crank gear 55a does not rotate and the upper arm 62a and the lower arm 72a do not open. The same applies to the crank arm 56b.

  FIGS. 35A and 35B are explanatory diagrams illustrating an example of setting the operation stop range of the crank arm 56a and the like. In this example, the circular shape shown in FIGS. 35A and 35B is the shape showing the locus of the crankshaft 551 shown in FIG. 34, that is, the locus line at the center of the crankshaft 551 with the rotation shaft 552 of the crank gear 55a as the origin O. It is. The rotation direction of the crank gear 55a is counterclockwise. A horizontal line O-Lu shown in FIG. 35A is a line segment connecting the top dead center Lu of the crank arm and the rotation shaft 552 of the crank gear 55a to the origin O. The line segment O-Lu is at 0 °. A top dead center Lu exists on the central locus of the crankshaft 551. The top dead center Lu is a position (0 °) where the rotation shaft 552 of the crank gear 55a, the crank shaft 551, and the shaft center of the crank arm 56a are connected on a straight line on the center locus.

  A range indicated by hatching in the drawing is a region where the immobilization is maintained even when the crank arm 56a is pushed from the direction of the line segment O-Lu. This region is defined by a crank angle θc ′ with the rotation axis 552 as the origin O. According to the crank drive mechanism 42a without the crank gear check mechanism 57a as a comparative example, the crank angle θc ′ = 2γ is an extremely narrow range centering on the line segment O-Lu. The crank angle θc ′ defines a range in which the crank gear 55a does not start to rotate by itself even when the crank arm 56a receives a reaction force. If the crank arm 56a is stopped within the crank angle θc ′, the crank drive is performed. Since various frictions and the like are acting on the mechanism 42a, the crank gear 55a does not rotate alone and the upper arm 62a and the lower arm 72a are not opened.

  On the other hand, according to the crank drive mechanism 42a to which the crank gear check mechanism 57a according to the present invention is attached, the operation stop is extremely wide such that the crank angle θc = γ + 160 ° centering on the line segment O-Lu shown in FIG. 35B. It becomes a range.

  This operation stop range is from the bottom dead center Ld of the crank arm 56a in which the upper arm 62a and the lower arm 72a are most expanded to the crank arm 56a in which the upper arm 62a and the lower arm 72a are most contracted. This is a range in which the crank arm 56a is advanced by γ after passing through the top dead center Lu. Within this range, the range from the bottom dead center Ld to the top dead center Lu is a range in which the check effect by the check gear 571 and the one-way clutch 574 can be obtained. Further, the range of γ is a range in which the crank gear 55a does not rotate by itself even when a reaction force acts on the crank arm 56a.

  The reason why the operation stop range can be set wide is that the check gear 571 can rotate only in one direction by the one-way clutch 574, but the crank gear 55a and the motor gear 55c can always rotate in the same direction.

  The crank angle θc defines a range in which the crank gear 55a does not start to rotate by itself even when the crank arm 56a receives a reaction force. If the crank arm 56a is stopped within the crank angle θc, the crank drive mechanism 42a. In addition, the non-return function by the one-way clutch 574, various types of friction, and the like act, so that the crank gear 55a does not rotate alone and the upper arm 62a and the lower arm 72a are not opened.

  The crank gear check mechanism 57a can increase the crank angle θc at which the crank arm 56a does not open, so that only the upper fan 62a and the lower arm 72a for the left fan stop before the top dead center Lu. However, the check gear 571 such as the one-way clutch 574 does not rotate reversely. Since the torque held by the crank gear check mechanism 57a does not lose the folding resistance of the package 1, the upper arm 62a and the lower arm 72a do not open to the left side, and the mountain fold mechanism 60 and the valley fold mechanism 70 Can be prevented from opening.

  Since the mountain fold mechanism 60 and the valley fold mechanism 70 do not open when the arm is closed and closed, as shown in FIG. become able to. Note that an arm open / close position detection sensor that detects whether or not the upper arm 62a and the lower arm 72a have reached the center is attached at a tangential position that does not exceed the top dead center Lu.

  Next, with reference to FIGS. 36 to 39, an example of the operation of the bag mouth fan forming drive unit 40 with a crank gear check function will be described. 36 and 38 are top views showing operation examples (Nos. 1 and 2) of the bag mouth fan forming drive unit 40, and FIGS. 37 and 39 are operation examples (80) of those crank gear check mechanisms 57a. It is an enlarged view showing °).

  In this example, the crank drive mechanism 42a for the left fan shown in FIG. 36 has a motor gear 55c, a crank, and the like when the fan left motor 59a rotates at the home position Ha of the upper arm 62a and the lower arm 72a shown in FIG. The gear 55a and the crank arm 56a are driven, and the lower arm 72a is contracted and closed with the rotating shaft 77a of the lower arm 72a as the rotating shaft.

  With this operation, the crank arm 56a is in the middle of the bottom dead center Ld and the top dead center Lu. This state is a process of focusing the left side of the package 1 and is a case where the crank gear 55a is rotated by 0 ° to 80 °. As shown in FIG. 37, the rotation shaft 552 of the crank gear 55a, the crankshaft 551, and the shaft center of the crank arm 56a are not connected on one straight line. In conjunction with this, the upper arm 62a operatively connected by the component connecting mechanism 66a shown in FIG. 27 is contracted and operated with the rotary bearing portion 13a as the rotational axis.

  Also, the right fan crank drive mechanism 42b shown in FIG. 36 operates in synchronism with the crank drive mechanism 42a. Therefore, in the home positions Hb of the upper arm 62b and the lower arm 72b shown in FIG. When the right fan motor 59b rotates, the motor gear 55d, the crank gear 55b, and the crank arm 56b are driven, and the lower arm 72b is contracted and closed with the rotating shaft portion 77b as the rotating shaft. With this operation, the crank arm 56b is in the middle of the bottom dead center Rd and the top dead center Ru. This state is a right-side focusing process of the package 1 and is a case where the crank gear 55b is rotated by 0 ° to 80 °. In conjunction with this, the upper arm 62b operatively connected by the component connecting mechanism 66b shown in FIG. 27 comes to perform a contracting operation with the rotary bearing portion 13b as the rotational axis.

  FIG. 38 is a top view showing an operation example (No. 2) of the crank arm 56a and the like, and FIG. 39 is an enlarged view showing an operation example (160 °) of the crank drive mechanism 42a. In this example, the crank drive mechanism 42a for the left fan shown in FIG. 38 is further changed from the state in which the crank arm 56a shown in FIG. 37 exists between the bottom dead center Ld and the top dead center Lu. Rotates. This is a case where the crank gear 55b is further rotated by 80 ° from 80 ° and rotated a total of 160 °. As the fan left motor 59a rotates, the motor gear 55c, the crank gear 55a, and the crank arm 56a are driven, and the contraction and closing operation of the lower arm 72a is continued with the rotation shaft portion 77a of the lower arm 72a as the rotation axis.

  By continuing this operation, the crank arm 56a reaches the top dead center Lu. In this state, the focusing process of the package 1 is completed. When the focusing process is completed, as shown in FIG. 39, the rotation shaft 552 of the crank gear 55a, the crankshaft 551, and the shaft center of the crank arm 56a are arranged on a substantially straight line. At this time, the one-way clutch 574 of the crank gear check mechanism 57a restricts the rotation direction of the crank gear 55a to one direction. Therefore, the mountain folding mechanism 60 and the valley folding mechanism 70 can be prevented from returning in the left fan side expansion direction.

  Also, in the right fan crank drive mechanism 42b shown in FIG. 38, the fan right motor 59b further rotates from the state in which the crank arm 56b shown in FIG. 37 exists in the middle of the bottom dead center Rd and the top dead center Ru. To do. By rotating the fan right motor 59b, the motor gear 55d, the crank gear 55b, and the crank arm 56b are driven, and the contraction / closing operation of the lower arm 72b is continued with the rotation shaft portion 77b of the lower arm 72b as the rotation axis.

  By continuing this operation, the crank arm 56b reaches the top dead center Ru. Since this state is the same as that shown in FIG. 37, the description thereof is omitted. At this time, the one-way clutch 574 of the crank gear check mechanism 57b restricts the rotation direction of the crank gear 55b to one direction. Therefore, the mountain folding mechanism 60 and the valley folding mechanism 70 can be prevented from returning in the right fan side expansion direction.

  40 to 42 are top views showing an operation example (without check) of the bag mouth fan forming drive unit 40 as a comparative example. According to the bag mouth fan forming drive unit 40 as the comparative example shown in FIG. 40, the crank gear check mechanisms 57a and 57b are not attached. As shown in FIG. 35A, when the crank arm 56a stops within the operation stop range of the crank angle θc ′ = 2α around the line segment O-Lu, various frictions and the like act on the crank drive mechanism 42a. Therefore, the crank gear 55a does not rotate alone and the upper arm 62a and the lower arm 72a are not opened.

  However, in the bag mouth fan drive unit 40 that is not provided with the crank gear check mechanisms 57a and 57b as a comparative example shown in FIG. 41, the crank is centered on the line segment O-Lu as shown in FIG. 35A. If the crank arm 56a cannot be stopped within the operation stop range of the angle θc ′ = 2γ, the crank drive mechanism 42a does not maintain the stop state and the crank gear 55a rotates as shown in FIG. The arm 62a and the lower arm 72a are opened.

  According to the crank drive mechanism 42a shown in FIG. 42, when the crank arm a deviates from the top dead center Lu, a straight line connecting the rotation shaft 552 of the crank gear 55a and the center of the crank arm 56a and the rotation shaft 552 of the crank gear 55a. A crank angle θx formed by a straight line connecting the axis centers of the two axes is generated. As the crank angle θx is larger, the resistance of the bag that the package 1 tries to return to its original shape becomes the force that rotates the crank gear 55a, and the rotation becomes easier.

  Therefore, by providing the crank drive mechanism 42a with the crank gear check mechanism 57a as shown in FIG. 32, the crank angle θc of the crank arm 56a can be widened as shown in FIG. 35B, and the operation stop range can be set wide. It becomes like this. The same applies to the crank arm 56b. By providing the crank gear check mechanism 57a from the setting of the severe crank angle θc ′ as in the comparative example, the range can be relaxed to the setting of the loose crank angle θc as in the invention and the check effect can be obtained. (Area) can be expanded.

  FIG. 43 is a perspective view of the bag mouth fan forming drive unit 40 showing an arrangement example of a crank gear check mechanism 57a 'as a modified example. 43 is provided with a crank gear check mechanism 57a 'on the surface side of the lower left chassis 36b. Even when the crank gear check mechanism 57a 'is arranged at this position, the rotation direction of the crank gear 55a can be restricted to one direction.

  For example, the crank gear check mechanism 57a 'is attached to the end of the rotation shaft 552 of the crank gear 55a, and operates so as to restrict the rotation direction of the crank gear 55a to one direction. In this example, a one-way clutch 574 is directly attached to the rotation shaft 552, and functions to restrict the rotation direction of the rotation shaft 552 to one direction (see FIG. 32).

  Although not shown, the crank gear check mechanism 57b 'is attached to the rotation shaft 554 of the crank gear 55b and operates so as to restrict the rotation direction of the crank gear 55b to one direction. For example, the one-way clutch 574 is directly attached to the rotating shaft 554. The one-way clutch 574 functions to restrict the rotation direction of the rotation shaft 554 to one direction (see FIG. 32).

  Thus, when the crank gear check mechanism 57a ′ is arranged in the crank drive mechanism 42a and the crank gear check mechanism 57b ′ is arranged in the crank drive mechanism 42b, the rotation direction of the crank gear 55a attached to the rotating shaft 552 is made uniform. The direction of rotation of the crank gear 55b attached to the rotating shaft 554 can be restricted to one direction.

  Therefore, the mountain folding mechanism 60 and the valley folding mechanism 70 can be prevented from returning in the expanding direction. When this method is adopted, the check gear 571 for meshing with the crank gear 55a is not necessary, and the number of parts is reduced, so that the cost can be reduced. In addition, since the one-way clutch 574 does not include the check gear 571, the one-way clutch 574 has an advantage that the accuracy of the crank angle corresponding to the backlash can be improved.

  Thus, according to the bag mouth fan folding tag binding device 100 according to the present invention, when the bag mouth of the package 1 having the folded surface II ′ is folded into a fan shape, the bag mouth fan forming drive unit. 40 is provided with crank drive mechanisms 42a, 42b. The crank drive mechanism 42a is provided with a crank gear check mechanism 57a, and the crank drive mechanism 42b is provided with a crank gear check mechanism 57b.

  The crank gear check mechanism 57a meshes with the crank gear 55a or is attached to the rotation shaft of the crank gear 55a to restrict the rotation direction of the crank gear 55a to one direction. The crank gear check mechanism 57b meshes with the crank gear 55b or is attached to the rotation shaft of the crank gear 55b to restrict the rotation direction of the crank gear 55b to one direction.

  Therefore, with the upper frames 11a and 11b closed with respect to the lower frames 21a and 21b, the mountain fold mechanism 60 slides and contracts along the upper guide rails 61a and 61b, and the lower guide rails 71a and 71b. Thus, the valley folding mechanism 70 that slides and contracts can be prevented from returning in the expanding direction.

  Thereby, the bellows-like bag folding state of the bag mouth of the package 1 folded by the mountain folding mechanism 60 and the valley folding mechanism 70 can be reliably maintained. Accordingly, it is possible to avoid a tag binding failure caused by a accordion fold failure of the bag mouth of the package 1. As a result, the bag mouth of the packaging body 1 containing food, other products, etc. is folded and automatically attached with a tag to the bundling portion, and the bag mouth fan is developed into a fan shape with the tag attaching portion as a key. The fold formation & tag binding device 100 can be provided.

  FIG. 44 is an enlarged perspective view of the bag mouth fan forming drive unit 40 showing an arrangement example of the arm opening / closing sensor. On the back surface of the upper left chassis 36a shown in FIG. 44, two sensors (hereinafter referred to as the left motor origin) for detecting the left fan side arm open / close, along with the check holder 577 of the crank gear check mechanism 57a of the crank drive mechanism 42a. Sensor 52a and left motor end sensor 52b). Optical sensors such as a transmissive photosensor are used for the left motor origin sensor 52a and the left motor end sensor 52b.

  For example, a wing-shaped sheet metal that shields the photosensor is attached to the rotation shaft 552 for the crank gear. The upper left chassis 36a is provided with a long hole for attaching a sensor. It is possible to adjust the mounting position of the sensor using this elongated hole.

  Although not shown, the rotation shaft 554 of the crank gear 55b of the crank drive mechanism 42b is similarly configured. For example, on the back surface of the upper left chassis 36a, along with the check holder 577 of the crank gear check mechanism 57b of the crank drive mechanism 42b, a right fan side arm open / close detection sensor (hereinafter, right motor origin sensor 53a, right motor) An end sensor 53b).

  Although not shown, the rotation shaft 542 of the crank gear 54a of the crank drive mechanism 41 is similarly configured. For example, two sensors (hereinafter referred to as a vertical origin sensor 51a and a vertical end sensor 51b) for detecting opening and closing of the upper and lower frames are disposed on the inner wall surface of the leg portion 33a. Optical sensors such as a transmissive photosensor are used for the vertical origin sensor 51a and the vertical end sensor 51b. For example, a wing-shaped sheet metal that shields the photosensor is attached to the rotation shaft 542 for the crank gear. The leg 33a is provided with a long hole for attaching the sensor. It is possible to adjust the mounting position of the sensor using this elongated hole.

  In this example, the control unit 50 outputs six position detection vertical origin sensors 51a, vertical end sensors 51b, left motor origin sensors 52a, left motor end sensors 52b, right motor origin sensors 53a, and right motor end sensors 53b. Accordingly, the crank driving mechanism 41 and the crank driving mechanisms 42a and 42b for performing the expanding and contracting operations of the upper band 63 and the lower band 73 are controlled.

  FIG. 45 is a block diagram illustrating a configuration example of a control system of the bag mouth fan forming drive unit 40. 45 has a control unit 50. The bag mouth fan drive unit 40 shown in FIG. Although not shown, the control unit 50 includes a memory such as a ROM (read only memory), a RAM (data read / write memory as needed), an HDD (fixed magnetic disk device), a CPU (central processing unit) having a calculation function, And an interface.

  The control unit 50 includes, in addition to an operation unit 901 including a start switch 90, six vertical origin sensors 51a, a vertical end sensor 51b, a left motor origin sensor 52a, a left motor end sensor 52b, a right motor for position detection. An origin sensor 53a and a right motor end sensor 53b are connected.

  The operation unit 901 includes a switch 90, which is operated when a series of processing such as folding of the bag mouth fan of the package 1 and attachment of the tag 10 is started. The switch 90 is provided at a predetermined position of the table 81 and is operated so as to drop the table 81 lightly. A switch-on signal SS9 generated by the operation unit 901 is output to the control unit 50.

  The vertical origin sensor 51a detects the bottom dead center Pd of the crank arm 54b and outputs a frame closing detection signal SPd to the control unit 50. The frame closing detection signal SPd is a signal indicating an operation (closing operation) in which the upper frames 11a and 11b are closed with respect to the lower frames 21a and 21b.

  The vertical end sensor 51 b detects the top dead center Pu of the crank arm 54 b and outputs a frame open detection signal SPu to the control unit 50. The frame open detection signal SPu is a signal indicating an operation (open operation) in which the upper frames 11a and 11b are opened with respect to the lower frames 21a and 21b.

  The control unit 50 performs frame up / down drive control based on the frame open detection signal SPu and the frame close detection signal SPd. In the frame vertical drive control, for example, from the state in which the mountain folding mechanism 60 is expanded with respect to the valley folding mechanism 70, the upper frames 11a and 11b are closed with respect to the lower frames 21a and 21b, Control is performed so that the mechanism 70 is substantially meshed to sandwich the folded surface II ′ of the bag mouth of the package 1.

  The left motor origin sensor 52a detects the bottom dead center Ld of the crank arm 56a and outputs an arm open detection signal SLd to the control unit 50. The arm open detection signal SLd is a signal indicating an open state in which the upper fan 62a and the lower arm 72a on the left fan side are opened in a bellows shape on the left side.

  The left motor end sensor 52 b detects the top dead center Lu of the crank arm 56 a and outputs an arm close detection signal SLu to the control unit 50. The arm closing detection signal SLu is a signal indicating the left fan side arm closed state in which the upper arm 62a and the lower arm 72a on the left fan side are brought close to the center.

  The control unit 50 executes left fan arm drive control based on the arm closing detection signal SLu and the arm opening detection signal SLd. In the left fan arm drive control, for example, the valley folding mechanism 70 on the left fan side is slid along the lower guide rails 71a and 71b to be contracted and the mountain folding mechanism 60 is connected to the upper guide via the component connecting mechanism 66a. Control is performed by sliding along the rails 61a and 61b to contract.

  The right motor origin sensor 53a detects the bottom dead center Rd of the crank arm 56b and outputs an arm open detection signal SRd. The arm open detection signal SRd is a signal indicating an open state in which the upper arm 62b and the lower arm 72b on the right fan side are opened in a bellows shape on the right side.

  The right motor end sensor 53b detects the top dead center Ru of the crank arm 56b and outputs an arm close detection signal SRu. The arm closing detection signal SRu is a signal indicating a closed state in which the upper arm 62b and the lower arm 72b on the right fan side are brought close to the center.

  The control unit 50 executes right fan arm drive control based on the arm closing detection signal SRu and the arm opening detection signal SRd. In the right fan arm drive control, the valley folding mechanism 70 on the right fan side is slid along the lower guide rails 71a and 71b to be contracted and the mountain folding mechanism 60 is connected to the upper guide rail 61a via the component connecting mechanism 66b. , 61b, and the control for contraction is performed.

In addition, a solenoid 108 and three motor driving units 110 to 112 for driving the crank mechanism are connected.

  The solenoid 108 is connected to the control unit 50. The solenoid 108 is excited based on the solenoid control signal S58. When the solenoid 108 is operated, the bobbin press is released and the twist tie can be extended. The solenoid control signal S58 is output from the control unit 50 to the solenoid 108.

  The motor drive unit 110 receives the motor drive data D10 from the control unit 50, decodes the data D10, and generates a motor control signal S10. A vertical motor 58 a is connected to the motor drive unit 110. The motor driving unit 110 drives the vertical motor 58a based on the motor control signal S10. When the vertical motor 58a rotates, the crank drive mechanism 41 operates. In the crank drive mechanism 41, when the vertical motor 58a rotates the crank gear 54a via the motor gear 54d, the crank gear 54a converts the motor rotational force into the reciprocating motion of the crank arm 54b.

  The motor drive unit 111 receives the motor drive data D11 from the control unit 50, decodes the data D11, and generates a motor control signal S11. A fan left motor 59 a is connected to the motor drive unit 111. The motor drive unit 111 drives the fan left motor 59a based on the motor control signal S11. When the fan left motor 59a rotates, the crank drive mechanism 42a operates. In the crank drive mechanism 42a, when the fan left motor 59a rotates the crank gear 55a, the crank gear 55a converts the motor rotational force into the reciprocating motion of the crank arm 56a.

  The motor drive unit 112 receives the motor drive data D12 from the control unit 50, decodes the data D12, and generates a motor control signal S12. A fan right motor 59b is connected to the motor drive unit 112. The motor driving unit 112 drives the fan right motor 59b based on the motor control signal S12. When the fan right motor 59b rotates, the crank drive mechanism 42b operates. In the crank drive mechanism 42b, when the fan right motor 59b rotates the crank gear 55b, the crank gear 55b converts the motor rotational force into the reciprocating motion of the crank arm 56b. The motor control signal S12 is output from the control unit 50 to the motor driving unit 112. Stepping motors are used as the vertical motor 58a, the fan left motor 59a, and the fan right motor 59b.

  By controlling the crank drive mechanisms 41, 42a, and 42b described above, the mountain fold mechanism 60 is slid along the upper guide rails 61a and 61b, and the valley fold mechanism 70 is moved to the lower guide rails 71a and 71b. Can be slid along and contracted. Thereby, a bellows-like crease can be attached to the folding surface of the bag mouth of the package 1 by the motor rotational force and the crank drive mechanisms 42a and 42b.

  The control unit 50 is connected to the communication unit 106, the display unit 107, and the buzzer 113 in addition to the solenoid 108 and the three motor driving units 110 to 112 for driving the crank mechanism. The communication unit 106 is connected to the tag attachment driving unit 101 and outputs a tag attachment request signal S41 and a bag mouth fan folding completion signal S41 '. The tag attachment request signal S41 is a signal for requesting attachment of the tag 10 to the binding site q. The bag mouth fan folding completion signal S41 'is a signal notifying that the bag mouth fan folding processing of the package 1 in the bag mouth fan forming drive unit and 40 is completed.

  The display unit 107 displays characters and video based on the display signal S07. The characters and video are contents for prompting replenishment of the tag 10 and the twist tie, error contents when an error occurs, and the like. The display signal S07 is output from the control unit 50 to the display unit 107. The buzzer 113 sounds a warning sound based on the buzzer sound signal S13. The buzzer sound signal S13 is output from the control unit 50 to the buzzer 113 when prompting the supply of the tag 10 or twist tie. The power supply unit 105 supplies, for example, DC24V to the control unit 50, the communication unit 106, the display unit 107, the solenoid 108, the motor driving units 110 to 112, and the like.

  Next, an operation example of the control system in the bag mouth fan forming drive unit 40 will be described. 46A to 46L are time charts showing an operation example in the bag mouth fan forming drive unit 40. The time chart of this embodiment is the one after the package 1 is inserted into the bag insertion slot as viewed from the bag insertion direction I and the switch 90 is turned on at time t1 on the time scale shown in FIG. 46A. The time scale indicates the time t set by the reference clock signal CLK.

  In this example, the control unit 50 turns on the solenoid 109 at time t3 after the switch is turned on. According to the operation state of the solenoid 108 for holding the bobbin shown in FIG. 46K, the solenoid control signal S58 rises from a low level (hereinafter referred to as “L” level) to a high level (hereinafter referred to as “H” level). The bobbin presser is released.

  At the same time, the control unit 50 drives the vertical motor 58a at time t3. According to the operation state of the vertical motor 58a shown in FIG. 46B, the motor control signal S10 rises from the “L” level to the “H” level at time t3, and the motor control signal S10 changes from the “H” level to “L” at time t5. Fall to the level. When the vertical motor 58a is operated, the crank driving mechanism 41 sandwiches the package 1 between the mountain folding mechanism 60 and the valley folding mechanism 70.

  Further, at time t3, the control unit 50 monitors the frame closing detection signal SPd from the vertical origin sensor 51a. According to the operation state of the vertical origin sensor 51a shown in FIG. 46C, the frame close detection signal SPd falls from the “H” level to the “L” level at time t3, and the frame close detection signal SPd at the “L” level at time t25. To “H” level.

  In this example, the left open / close fan left motor 59a and the right open / close fan right motor 59b are driven at time t4 after 300 ms has elapsed from the start of driving of the vertical motor 58a at time t3. According to the operation state of the fan left motor 59a shown in FIG. 46E, the motor control signal S10 falls from "H" level to "L" level at time t4, and the fan left motor 59a is moved counterclockwise by a predetermined number of steps. Rotate (CCW rotation). The fan left motor 59a rotates and the crank drive mechanism 42a operates. When the crank gear 55a is rotated by the crank drive mechanism 42a, the upper arm 62a and the lower arm 72a are closed, and the left half of the package 1 is converged.

  At the same time, according to the operating state of the fan right motor 59b shown in FIG. 46H, the motor control signal S12 falls from the “H” level to the “L” level, and the fan right motor 59b rotates CCW by a predetermined number of steps. The right fan motor 59b rotates and the crank drive mechanism 42b operates. When the crank gear 55b is rotated by the crank drive mechanism 42b, the upper arm 62b and the lower arm 72b are closed, and the right half of the package 1 converges.

  At the same time, at time t4, the control unit 50 monitors the arm opening detection signal SLd from the left motor origin sensor 52a. According to the operation state of the left motor origin sensor 52a shown in FIG. 46F, the arm open detection signal SLd falls from the “H” level to the “L” level at time t4, and the arm open detection signal SLd becomes “L” at time t22. The level rises from the “level” to the “H” level.

  Further, at time t4, the control unit 50 monitors the arm open detection signal SRd from the right motor origin sensor 53a. According to the operation state of the right motor origin sensor 53a shown in FIG. 46I, the arm open detection signal SRd falls from the “H” level to the “L” level at time t4, and the arm open detection signal SRd becomes “L” at time t22. The level rises from the “level” to the “H” level.

  In this example, in order to attach a tag to the bundled package 1, the bag mouth fan drive unit 40 outputs a tag attachment preparation completion signal to the tag attachment drive unit 101 at time t5 to attach the tag 10 to the binding site q. Preparation for installation is made.

  According to the operation state of the vertical end sensor 51b shown in FIG. 46D, the frame closing detection signal SPd rises from the “L” level to the “H” level at time t5, and the frame closing detection signal SPd from the “H” level at time t25. Fall to the “L” level.

  In this example, the top dead center Lu of the crank arm 56a is detected at time t6. According to the operation state of the left motor end sensor 52b shown in FIG. 46G, the arm closing detection signal SLu rises from the “L” level to the “H” level at time t6, and the arm closing detection signal SLu is at the “H” level at time t24. To “L” level.

  Since this detection detects the top dead center Lu of the crank arm 56a, the motor control signal S11 rises from the “L” level to the “H” level, and the fan left motor 59a stops.

  Similarly, the top dead center Ru of the crank arm 56b is detected at time t6. According to the operation state of the right motor end sensor 53b shown in FIG. 46J, the arm closing detection signal SRu rises from the “L” level to the “H” level at time t6, and the arm closing detection signal SRu is at the “H” level at time t24. To “L” level. Since this detection detects the top dead center Ru of the crank arm 56b, the motor control signal S12 rises from the CCW = “L” level to the CW = “H” level, and the right fan motor 59b stops. In this example, a tag attachment request signal S41 as shown in FIG. 46L is output from the control unit 50 to the tag attachment drive unit 101 at time t6.

  Then, after stopping the fan left motor 59a and the fan right motor 59b, the solenoid 109 is turned off after 200 ms. According to the operation state of the solenoid 109 shown in FIG. 46K, when the solenoid control signal S58 falls from the “H” level to the “L” level, the bobbin is pressed and the feeding of the twist tie 2 is restrained.

  In this example, the tag 10 is attached to the binding site q of the package 1 in the tag attachment drive unit 101 between time t6 and time t21 (see FIGS. 116 and 117).

  Thereafter, the driving of the fan left motor 59a and the fan right motor 59b is started at time t22. When the left motor origin sensor 52a detects the bottom dead center Ld at time t24, the fan left motor 59a is stopped. Similarly, when the right motor origin sensor 53a detects the bottom dead center Rd at time t24, the fan right motor 59b is stopped.

  Then, after 50 ms elapses at time t23, driving of the vertical motor 58a is started. When the vertical origin sensor 51a detects the bottom dead center Pd at the time t25 after the start of the motor drive, the vertical motor 58a is stopped, so that the bag mouth fan forming drive unit 40 becomes the tag mounting drive unit 101 (conveying board) at the time t25. A bag mouth fan folding completion signal S41 ′ as shown in FIG. 46L is output.

  By these, the bag mouth fan shaping drive unit 40 operates. In the tag attachment drive unit 101 described below, the tag 10 is bound by the twist tie 2 to the binding portion q of the bag mouth of the package 1 that is focused at the center by the mountain fold mechanism 60 and the valley fold mechanism 70. explain.

  Next, a configuration example of the tag attachment drive unit 101 that inserts the twist tie 2 into the tag 10 and binds it to the bag mouth of the package 1 will be described. FIG. 47 is a perspective view showing a configuration example of the tag attachment drive unit 101. A tag attachment drive unit 101 shown in FIG. 47 is an example of a tag attachment device, and includes a tag feed mechanism 3, a tag transport mechanism 4, a twist tie feed mechanism 5, a twist tie set mechanism 6, a twist tie cut mechanism 7, and a twist tie twist mechanism. 8 (see FIG. 74) and an ascending / descending mechanism 20 are provided.

  The tag feeding mechanism 3 is provided above the cartridge 17 detachably provided in the apparatus main body, and feeds only one uppermost tag 10 of the cartridge 17 by roller driving and supplies it to the tag transport mechanism 4.

  The tag transport mechanism 4 includes a tag hook 43. The tag hook 43 is attached so as to be movable forward and backward by a trapezoidal screw 4b (see FIG. 53) which is an example of a moving means. The tag hook 43 hooks the claw portion 43a (see FIG. 55) on the concave portion 10e (see FIG. 49A) of the tag 10 and conveys the tag 10 to the twist tie set mechanism 6. The claw portion 43a is an example of a hook portion.

  The twist tie setting mechanism 6 is disposed on a substantially extended line in the entry direction of the twist tie 2 shown in FIG. The twist tie set mechanism 6 includes a pair of wing claws 6a. The wing claw 6a is an example of a claw member, and presses both ends of the mounting portion 10c in the vicinity of the mounting hole 10d of the tag 10 to form the mounting portion 10c into a substantially trapezoidal shape (see FIG. 71B). Thus, the tag 10 can be formed into a shape that allows a substantially straight line to pass through the mounting holes 10d and 10d. In this state, the twist tie setting mechanism 6 inserts the twist tie 2 sent out from the twist tie feed mechanism 5 through the mounting holes 10d and 10d of the tag 10.

  The twist tie feed mechanism 5 is an example of a binding tool feed mechanism. The twist tie feed mechanism 5 is provided in the vicinity of the twist tie set mechanism 6 and pulls out the twist tie 2 wound around the bobbin 58 and sends it to the twist tie set mechanism 6. The twist tie feed mechanism 5 includes a twist tie feed motor 5a and a guide roller 5b. The twist tie feed motor 5a is an example of a tie feed motor, and functions as a drive source that feeds the twist tie 2. The guide roller 5 b is rotatably provided at the entrance of the twist tie feed mechanism 5. The guide roller 5b keeps the entry direction of the twist tie 2 constant.

  An ascending / descending mechanism 20 is provided between the chassis plate 44a and the chassis plate 44b. The ascending / descending mechanism 20 ascends or descends the tag transport mechanism 4 and the twist tie set mechanism 6 with a trapezoidal screw that is driven in the vertical direction.

  Subsequently, an operation example of the tag attachment drive unit 101 will be described. The tag feeding mechanism 3 feeds only one uppermost tag 10 out of the tags 10 stacked on the cartridge 17 and supplies it to the tag transport mechanism 4. The tag hook 43 of the tag transport mechanism 4 hooks the claw portion 43a (see FIG. 55) on the recess 10e of the tag 10 and transports the tag 10 to the twist tie set mechanism 6.

  The wing claws 6a of the twist tie set mechanism 6 are formed into a shape in which a substantially straight line can pass through the mounting holes 10d and 10d of the tag 10 by pressing both ends of the mounting portion 10c of the tag 10. Then, the twist tie setting mechanism 6 allows the twist tie 2 sent out from the twist tie feed mechanism 5 to be inserted into the mounting holes 10 d and 10 d of the tag 10.

  After inserting the twist tie 2 into the mounting holes 10d, 10d, the ascending / descending mechanism 20 raises the tag transport mechanism 4 and the twist tie setting mechanism 6. At this time, the twist tie cut mechanism 7 which is an example of a binding tool cut mechanism cuts the twist tie 2 into a predetermined length. After cutting, the twist tie setting mechanism 6 opens the pair of wing claws 6a and shapes the twist tie 2 cut by the twist cut mechanism 7 into a U shape. Then, the twist tie set mechanism 6 delivers both ends of the twist tie 2 formed in a U shape to the twist tie twist mechanism 8.

  The twist tie twisting mechanism 8 is an example of a binding tool twisting mechanism, and holds both ends of the cut twist tie 2 and rotates by two and a half rotations as an example. 48B, the twist tie 2 can be fastened by tightening the bag mouth 1a of the package 1, and the tag 10 can be attached by the twist tie 2.

  Next, an example of the package 1 that has been bound by the tag attachment drive unit 101 will be described. FIG. 48A is a perspective view showing a configuration example of the package 1 before the bundling process. The package 1 shown in FIG. 48A is made of, for example, a resin material, and the bag mouth 1a is closed by a thermocompression treatment or the like. The package 1 wraps items such as confectionery and giveaways.

  FIG. 48B is a perspective view showing an example of the package 1 that is bundled by the tag attachment drive unit 101 shown in FIG. The bag mouth 1a of the package 1 shown in FIG. 48B is formed in a fan shape in which mountain folding and valley folding are repeated by the bag mouth fan folding tag binding device 100. Further, the binding site q of the package 1 is bound by a twist tie 2 and a tag 10 is attached by the twist tie 2. Thus, the package 1 is bound by the twist tie 2 and the tag 10 is attached, and the bag mouth 1a is formed in a fan shape.

  Next, a configuration example of the tag 10 will be described. FIG. 49A is a front view showing a configuration example of the tag 10 used in the tag attachment drive unit 101. FIG. FIG. 49B is a perspective view illustrating a configuration example of the tag 10. 49A and 49B includes an information presentation unit 10a, a mounting unit 10c, and a connecting unit 10b that are integrally formed of a thin plate material such as paper or plastic.

  The connecting portion 10b is a region surrounded by two broken lines shown in FIG. 49A. This region is defined by the boundary line between the mounting part 10c and the connecting part 10b and the boundary line between the connecting part 10b and the information presenting part 10a. Various information is displayed on the information presentation unit 10a by printing or the like. Further, a seal member on which various information is printed may be attached. Furthermore, information stamped such as Braille may be described.

  The mounting portion 10c is provided with two mounting holes 10d and 10d and is locked to the twist tie 2 after cutting. The mounting holes 10d and 10d form two through holes with a predetermined interval in the horizontal direction of the tag 10 when the longitudinal direction of the tag 10 is the vertical direction and the short direction of the tag 10 is the horizontal direction. Configured.

  Concave portions 10e and 10e are formed in the connecting portion 10b by cutting out part of both sides of the information presentation portion 10a into a predetermined shape. The recesses 10e and 10e are an example of locking portions. The connecting portion 10b connects the mounting portion 10c and the information presenting portion 10a with a narrower width than the information presenting portion 10a. In this way, the tag 10 is configured.

  FIG. 50 is a perspective view illustrating a configuration example of the twist tie 2. The twist tie 2 shown in FIG. 50 is configured by covering a thin wire 2a as a core wire of plastic or metal with a covering material 2b such as resin or paper. The twist tie 2 has a narrow tape shape (band shape), and is passed through the attachment holes 10 d and 10 d of the tag 10 and fastened to the package 1.

  Next, a configuration example of the tag feeding mechanism 3 will be described. FIG. 51 is a perspective view showing a configuration example of the tag feeding mechanism 3. 51 is in a state in which the roller frame 37 and the reverse roller frame 38 are removed from the tag attachment drive unit 101 shown in FIG. A tag mounting drive unit 101 shown in FIG. 51 has a plurality of tags 10 stacked and loaded on a cartridge 17. The tag feeding mechanism 3 feeds only one tag 10 loaded in the cartridge 17 to the tag transport mechanism 4.

  The tag feeding mechanism 3 includes a pickup roller 39a, a feed roller 39b, and a brake roller 39c. The rollers 39a to 39c are made of a rubber material as an example. The pickup roller 39a and the feed roller 39b are arranged side by side in the feed direction of the tag 10. The brake roller 39c is disposed directly below the feed roller 39b.

  The pick-up roller 39a is rotated while being in contact with the uppermost tag 10 loaded in the cartridge 17, thereby feeding out the uppermost tag 10 by friction to feed it to the feed roller 39b and the brake roller 39c. The feed roller 39 b and the brake roller 39 c sandwich the tag 10 and send the tag 10 to the tag hook 43.

  The pickup roller 39a is fixed to the pickup roller shaft 39d, and the feed roller 39b is fixed to the feed roller shaft 39e. The brake roller 39c is fixed to the brake roller shaft 39f. In order to rotate the roller shafts 39d to 39f, a tag feed motor 39k, a motor gear 39m, a drive gear 39n, a shaft 39p, and belts 39g to 39i are provided.

  The pickup roller shaft 39d, the feed roller shaft 39e, the tag feed motor 39k, and the shaft 39p are fixed by the roller frame 37 shown in FIG. 47, and their positions are set constant. The brake roller shaft 39f is fixed to the reverse roller frame 38 shown in FIG. 47, and its position is set to be movable. The reverse roller frame 38 is provided so as to be rotatable about a shaft 39p. The reverse roller frame 38 is biased upward by a tension spring 38a. The tension spring 38 a is attached to a mounting plate 38 b provided on the roller frame 37 and a bottom portion 38 c of the reverse roller frame 38.

  The tag feed motor 39k shown in FIG. 51 is provided with a motor gear 39m, and the shaft 39p is provided with a drive gear 39n. The motor gear 39m and the drive gear 39n are engaged with each other. Thereby, the power of the tag feed motor 39k is transmitted to the shaft 39p. The shaft 39p and the feed roller shaft 39e are connected by a belt 39g with a pulley interposed. The shaft 39p and the brake roller shaft 39f are drivingly connected by a belt 39h with a pulley interposed. The pickup roller shaft 39d and the feed roller shaft 39e are drivingly connected by a belt 39i with a pulley interposed.

  The brake roller shaft 39f is provided with a torque limiter 39j. The torque limiter 39j controls whether or not the power from the tag feed motor 39k is transmitted to the brake roller 39c. In this example, the brake roller 39c is pressed against the feed roller 39b. As described above, the brake roller shaft 39f is urged upward by the tension spring 38a shown in FIG. 47 and is rotatably provided.

  When only one tag 10 enters between the feed roller 39b and the brake roller 39c, or when the rollers 39b and 39c are in direct contact with each other, torque transmitted by the frictional force between the tag 10 and the rollers 39b and 39c As a result, the torque limiter 39j slides. For this reason, the brake roller 39c rotates with the feed roller 39b.

  Further, when two tags 10 enter between the feed roller 39b and the brake roller 39c, the friction force between the overlapping tags 10 is smaller than the friction force between the rollers 39b, 39c and the tag 10, so that the feed roller 39b The torque received from the motor becomes smaller and the torque limiter 39j does not slip. For this reason, the brake roller 39c rotates in the same direction as the feed roller 39b without being accompanied by the feed roller 39b. Thereby, since the second tag 10 moves backward, it is possible to prevent the second tag 10 from being sent out. Therefore, only one tag 10 can be sent out.

  With this configuration, the pickup roller 39a and the feed roller 39b arranged side by side in the feed-out direction of the tag 10 always rotate in the same direction and feed the tag 10 out. When only one tag 10 is fed out by the pickup roller 39a, the brake roller 39c arranged immediately below the feed roller 39b slides around the feed roller 39b with the torque limiter 39j sliding. Further, when two tags 10 are fed out by the pickup roller 39a, the brake roller 39c rotates in the same direction as the feed roller 39b without slipping the torque limiter 39j and moves the second tag 10 backward.

  Subsequently, an operation example of the tag feeding mechanism 3 will be described. 52A to 52D are schematic diagrams illustrating an operation example of the tag feeding mechanism 3. In this example, when the pickup roller 39a shown in FIG. 52A feeds and sends out the first tag 10-1 positioned at the top of the cartridge 17, the second stacked below the first tag 10-1. It is assumed that the tag 10-2 is also taken out by the first tag 10-1.

  The pick-up roller 39a shown in FIG. 52A rotates in the direction of the arrow Rt and feeds and sends out the first tag 10-1 positioned at the top of the cartridge 17. The feed roller 39b rotates in the direction of arrow Rt, and the brake roller 39c rotates in the direction of arrow Lt.

  Since the feed roller 39b and the brake roller 39c are in direct contact with each other, the torque limiter 39j slides due to the torque transmitted by the frictional force between the rollers 39b and 39c. For this reason, the brake roller 39c rotates with the feed roller 39b in the direction of the arrow Lt.

  As shown in FIG. 52B, when two tags 10 enter between the feed roller 39b and the brake roller 39c, the frictional force between the overlapping tags 10-1 and 10-2 is caused by the rollers 39b and 39c and the tag. It becomes smaller than the frictional force between 10-1 and 10-2. For this reason, the torque limiter 39j does not slip because the torque received from the feed roller 39b decreases. Accordingly, the brake roller 39c rotates in the direction of the arrow Rt without being rotated with the feed roller 39b.

  At this time, as shown in FIG. 52C, the second tag 10-2 moves backward by the rotation of the brake roller 39c, and the first tag 10-1 moves forward by the rotation of the feed roller 39b. Thereby, as shown in FIG. 52D, the first tag 10-1 and the second tag 10-2 can be separated, so that only one tag 10-1 can be sent out.

  Next, a configuration example of the tag transport mechanism 4 that transports the tag 10 sent out by the tag feeding mechanism 3 will be described. FIG. 53A is a perspective view illustrating a configuration example of the tag transport mechanism 4. FIG. 53B is a top view illustrating a configuration example of the tag transport mechanism 4. 53A and 53B includes a horizontal motor 4a, a trapezoidal screw 4b, a tag hook shaft 4c, a nut 4d, and a tag hook 43.

  The horizontal motor 4a is a DC motor and rotates a trapezoidal screw 4b which is an example of a ball screw. For example, the trapezoidal screw 4b is provided with a drive gear 4j at the tip thereof, the horizontal motor 4a is provided with a motor gear 4h, and the drive gear 4j and the motor gear 4h are engaged with and connected to the connecting gear 4i. When the horizontal motor 4a is rotationally driven, the trapezoidal screw 4b is rotated.

  A nut 4d is screwed to the trapezoidal screw 4b. When the trapezoidal screw 4b rotates, the nut 4d moves forward or backward in accordance with the rotation direction. A tag hook 43 is attached to the nut 4d with four stepping pins 4f. A compression spring 4k is interposed at the tip of these four stepping pins 4f. The tag hook 43 is urged toward the flange 4m side of the nut 4d by these compression springs 4k, and is coupled to the flange 4m of the nut 4d so as to be able to contact and separate.

  Thereby, when the tag hook 43 is moved forward and brought into contact with the curl guide 45 and stopped at the binding position, the positioning of the tag hook 43 can be accurately set with a simple configuration.

  It is also conceivable to control the number of rotations of the trapezoidal screw 4b so that the tag hook 43 stops at a specified position. However, there is a problem that the stop position of the tag hook 43 fluctuates due to wear of the trapezoidal screw 4b, variation of the horizontal motor 4a, variation in assembly, or the like.

  The tag hook 43 includes a linear ball bearing 4e at the lower part thereof. The linear ball bearing 4e is slid on the tag hook shaft 4c. The linear ball bearing 4e and the tag hook shaft 4c are an example of a posture maintaining member, and have a function of maintaining the posture of the nut 4d and the tag hook 43 constant without rotating the nut 4d when the tag hook 43 is moved.

  Each of the claw portions 43a of the tag hook 43 has a circular opening 43b, and the guide rod 4g is inserted into the circular opening 43b. The guide rod 4g is an example of a guide member, and supports the tag 10 that moves forward by being hooked by the claw portion 43a of the tag hook 43 substantially horizontally with respect to the advancing direction of the tag 10. That is, the tag 10 is conveyed while sliding on the guide rod 4g while maintaining a state substantially parallel to the two guide rods 4g.

  FIG. 54 is a cross-sectional view illustrating a configuration example of a main part of the tag transport mechanism 4. A tag hook 43 of the tag transport mechanism 4 shown in FIG. 54 has a T-shaped nut 4d fitted in a nut opening 43d at substantially the center. The tag hook 43 is urged and brought into contact with the flange 4m side of the nut 4d by the stepping pin 4f and the compression spring 4k. Thereby, the tag hook 43 is fixed to the flange 4m of the nut 4d so as to be able to contact and separate.

  FIG. 55 is a perspective view showing a configuration example of the tag hook 43. The tag hook 43 shown in FIG. 55 is formed from a metal material as an example. Of course, the tag hook 43 may be formed by injection molding a resin material. The claw portions 43 a and 43 a provided on the upper portion of the tag hook 43 include an inclined portion 43 g that is formed obliquely with respect to the tag delivery direction U. The tip of the mounting portion 10c of the tag 10 fed out from the tag feeding direction U comes into contact with the inclined portion 43g and gets over the claw portion 43a. Thereby, the recessed part 10e of the tag 10 is hooked on the claw part 43a.

  Further, the tag hook 43 includes openings 43f for inserting the stepping pins 4f at four locations around the nut opening 43d. Further, the tag hook 43 includes an opening 43e for mounting the linear ball bearing 4e on the lower part thereof. The claw portions 43a of the tag hook 43 are each provided with a circular opening 43b, and the guide rod 4g is inserted into the circular opening 43b. The tag hook 43 is provided with a contact surface 43c for contact with the curl guide 45 for positioning. Thus, the tag hook 43 is configured.

  Next, an operation example of the tag transport mechanism 4 will be described. FIG. 56A is a perspective view showing an operation example of the tag transport mechanism 4. FIG. 56B is a top view showing an operation example of the tag transport mechanism 4. 56A and 56B, when the horizontal motor 4a is rotationally driven, power is transmitted through the motor gear 4h, the coupling gear 4i, and the drive gear 4j, and the trapezoidal screw 4b rotates.

  When the trapezoidal screw 4b rotates, the nut 4d advances in accordance with the rotation direction. At this time, the tag hook 43 moves forward while maintaining a constant posture by the linear ball bearing 4e and the tag hook shaft 4c.

  The tag hook 43 comes into contact with the curl guide 45 at the contact surface 43c. Immediately after the contact surface 43c of the tag hook 43 contacts the curl guide 45, the rotation of the horizontal motor 4a is stopped. At this time, the tag hook 43 abuts on the curl guide 45 and is positioned, and stops at a predetermined binding position. As shown in FIG. 56A, the nut 4d stops in a state where it is separated from the tag hook 43 and slightly advanced. In this case, the compression spring 4k is compressed and bent by the distance that the nut 4d is separated from the tag hook 43.

  By positioning the tag hook 43 in this way, the positioning of the tag hook 43 can be accurately set with a simple configuration. Further, when the tag hook 43 comes into contact with the curl guide 45, the impact can be reduced by the compression spring 4k.

  FIG. 57 is a cross-sectional view showing an operation example of a main part of the tag transport mechanism 4. The tag hook 43 of the tag transport mechanism 4 shown in FIG. 57 is in a stopped state in contact with the curl guide 45. At this time, the nut 4d shown in FIG. 57 stops in a state of being slightly advanced away from the tag hook 43 by a distance N1. In this case, the compression spring 4k is compressed by the distance N1.

  By positioning the tag hook 43 in this way, the positioning of the tag hook 43 can be accurately set with a simple configuration. Further, when the tag hook 43 comes into contact with the curl guide 45, the impact can be reduced by the compression spring 4k.

  When the trapezoidal screw 4b rotates reversely and the nut 4d retracts, the compression spring 4k that has been compressed and bent expands by a distance N1. Then, the distance N1 at which the nut 4d and the tag hook 43 are separated from each other is eliminated, the flange 4m of the nut 4d is brought into contact with the tag hook 43, and the tag hook 43 is also retracted to the position shown in FIG. 54 as the nut 4d is retracted.

  Subsequently, a series of operation examples for feeding and conveying the tag 10 will be described. FIG. 58 is a perspective view showing an operation example (No. 1) of the tag feeding mechanism 3 and the tag carrying mechanism 4. The tag feeding mechanism 3 shown in FIG. 58 is a state in which only one uppermost tag 10 of the cartridge 17 is fed to the tag transport mechanism 4.

  In order to feed the tag 10 in this way, the tag feed motor 39k is rotationally driven to transmit power to the shaft 39p via the motor gear 39m and the drive gear 39n to rotate the shaft 39p. Due to the rotation of the shaft 39p, the pickup roller 39a and the feed roller 39b are simultaneously rotated. The pickup roller 39a feeds the uppermost tag 10 loaded in the cartridge 17 and sends it to the feed roller 39b. The feed roller 39b sends out only one tag 10 to the tag hook 43 in cooperation with the brake roller 39c shown in FIG. When the two tags 10 are slid out by the pickup roller 39a, the pickup roller 39a moves the second tag 10 backward as shown in FIGS. 52A to 52D, and the feed roller 39b sets the first tag 10 Only the tag hook 43 is sent out.

  FIG. 59A is a perspective view showing an operation example of a main part of the tag feeding mechanism 3. FIG. 59B is a top view showing an operation example of the main part of the tag feeding mechanism 3. The pick-up roller 39a shown in FIGS. 59A and B feeds the uppermost tag 10 loaded in the cartridge 17 and sends it to the feed roller 39b. The feed roller 39 b and the pickup roller 39 a send the tag 10 to the tag hook 43.

  A tag presser plate 47 is provided downstream of the feed roller 39b. The tip 47 a of the tag presser plate 47 is set upward with respect to the feed direction of the tag 10. Further, the rear end 47 b of the tag presser plate 47 is set downward with respect to the feed direction of the tag 10. Thereby, the tag pressing plate 47 picks up the mounting portion 10c of the tag 10 with the front end 47a and presses it with the rear end 47b as the tag 10 is sent out from the pickup roller 39b.

  59C is a cross-sectional view taken along arrow H1-H1 in FIG. 59B, illustrating an operation example of a main part of the tag feeding mechanism 3. The mounting portion 10c of the tag 10 shown in FIG. 59C is pressed by the tag pressing plate 47 and gets over the claw portion 43a of the tag hook 43. The recess 10 e of the tag 10 is hooked on the claw portion 43 a of the tag hook 43.

  FIG. 60 is a perspective view showing an operation example (No. 2) of the tag feeding mechanism 3 and the tag carrying mechanism 4. The tag transport mechanism 4 shown in FIG. 60 is in the middle of transporting the tag 10 to the twist tie set mechanism 6 by the tag hook 43. At this time, the tag feeding mechanism 3 is stopped. That is, the tag feed motor 39k is stopped and the pickup roller 39a and the feed roller 39b are not driven to rotate.

  The tag transport mechanism 4 drives and rotates the horizontal motor 4a shown in FIG. 53A to transmit power to the trapezoidal screw 4b via the motor gear 4h, the connection gear 4i, and the drive gear 4j to advance the tag hook 43. A recess 10 e of the tag 10 is hooked on the claw portion 43 a of the tag hook 43. For this reason, the tag 10 advances while keeping the horizontal state supported by the two guide rods 4g and 4g as the tag hook 43 advances.

  61A is a perspective view illustrating an operation example of a main part of the tag transport mechanism 4. FIG. FIG. 61B is a top view illustrating an operation example of a main part of the tag transport mechanism 4. 61C is a cross-sectional view taken along arrow H2-H2 in FIG. 61B. The tag hook 43 shown in FIGS. 61A to 61C moves forward with the recess 10e of the tag 10 hooked on the claw portion 43a. The two guide rods 4g and 4g support the tag 10 so as to keep the tag 10 horizontal.

  FIG. 62 is a perspective view showing an operation example (No. 3) of the tag feeding mechanism 3 and the tag carrying mechanism 4. The tag transport mechanism 4 shown in FIG. 62 is in a state where the tag 10 is transported to the twist tie set mechanism 6 by the tag hook 43.

  The tag transport mechanism 4 drives and rotates the horizontal motor 4a shown in FIG. 56A to transmit power to the trapezoidal screw 4b via the motor gear 4h, the connection gear 4i, and the drive gear 4j to further advance the tag hook 43. The tag hook 43 comes into contact with the curl guide 45 and stops.

  FIG. 63A is a perspective view illustrating an operation example of a main part of the tag transport mechanism 4. FIG. 63B is a top view illustrating an operation example of a main part of the tag transport mechanism 4. 63C is a cross-sectional view taken along arrow H3-H3 in FIG. 63B. The tag hook 43 shown in FIGS. 63A to 63C moves forward with the claw portion 43a hooking the recess 10e of the tag 10, and the contact surface 43c of the tag hook 43 contacts the curl guide 45 and stops. The tag hook 43 is positioned in contact with the curl guide 45 and stopped at a predetermined position. As for the tag 10 conveyed to the tag hook 43, the twist tie 2 is inserted into the mounting hole 10d by the twist tie setting mechanism 6.

  As described above, according to the tag mounting drive unit according to the present invention, the trapezoidal screw 4b for moving the tag hook 43 having the claw portion 43a hooked to the concave portion 10e of the tag 10 to advance or retreat is provided, and the tag hook 43 is hooked to the claw portion 43a. The tag 10 that moves forward is supported by the guide rod 4g substantially horizontally with respect to the direction in which the tag 10 moves forward.

  With this configuration, the tag 10 can be transported to the binding position without providing an obstructing mechanism on one side of the tag 10 on which the package 1 is disposed. Thereby, the tag 10 can be attached to the package 1 arranged on the one side. Further, if only the shapes of the edge 10e 'and the edge 10e "of the edges that define the recess 10e of the tag 10 to be hooked by the tag hook 43 are unified, for example, the shape of the information presentation unit 10a of the tag 10 may be circular.

  Next, a configuration example of the twist tie set mechanism 6 will be described. FIG. 64 is an overall perspective view showing a configuration example of the twist tie set mechanism 6. FIG. 65 is a perspective view showing a configuration example of a main part of the twist tie set mechanism 6. 66 is a perspective view showing a configuration example of a main part of the twist tie set mechanism 6 from which the wing base 6b shown in FIG. 65 and members related to the wing base 6b are removed.

  The twist tie setting mechanism 6 shown in FIG. 64 places the tag 10 transported by the tag transport mechanism 4 in a predetermined state, and inserts the twist tie 2 pulled out from the bobbin 58 into the mounting hole 10d of the tag 10. .

  A twist tie set mechanism 6 shown in FIG. 65 includes a right wing portion 6R and a left wing portion 6L. The right wing portion 6R and the left wing portion 6L are arranged to face each other and have substantially the same configuration.

  The right wing portion 6R includes a wing claw 6a, a wing base 6b, a wing closer 6c, a right alignment motor 6h, and a trapezoidal screw 6n. The wing base 6b is an example of a base member, and the wing closer 6c is an example of a closer member. The wing base 6b has a shape in which both ends of the flat plate are folded vertically. The front of the wing base 6b is pivotally supported by a wing arm shaft 6k which is an example of an arm shaft member. A pin 6f is provided behind the wing base 6b. A tension spring 6g having one end fixed to the pin 6m is hooked on the pin 6f. The tension spring 6g is an example of an urging member, and urges the wing base 6b toward the wing closer 6c with the wing arm shaft 6k as a rotation shaft.

  At approximately the center of the wing base 6b, projecting pieces 6j having holes 6q are erected at both ends. A release pin 6e is inserted into the hole 6q of the protruding piece 6j. The release pin 6e is an example of a release member, and is supported by a support plate 6d shown in FIG. The support plate 6d has an L-shaped plate shape and is fixed on a chassis plate 44a shown in FIG. The tip 6r of the support plate 6d has a step. The release pin 6e is hooked by a step at the tip 6r.

  The wing closer 6c of the right wing portion 6R is engaged with a trapezoidal screw 6n. This trapezoidal screw 6n is driven by a right-justified motor 6h, and slides the wing closer 6c back and forth.

  The wing claw 6a is engaged with the wing closer 6c by inserting the wing arm shaft 6k and the hole engaging pin 6s. The wing closer 6c has a horizontal long hole 6p and an inclined long hole 6t. The inclined long hole 6t is opened in a direction inclined with respect to the sliding direction of the wing closer 6c. The horizontal long hole 6p is opened in the horizontal direction with respect to the sliding direction of the wing closer 6c.

  A wing arm shaft 6k is inserted into the horizontal long hole 6p, and a hole engaging pin 6s, which is an example of a hole engaging shaft member, is inserted into the inclined long hole 6t. When the wing closer 6c moves forward or backward, the posture of the wing claw 6a is regulated by the hole engaging pin 6s and the inclined elongated hole 6t, and rotates with the wing arm shaft 6k as a rotation axis.

  Protruding pieces 6v are erected on both rear ends of the wing closer 6c. The protruding piece 6v is fitted into a long opening 6i opened in the wing base 6b. The rectangular opening 6i is an example of a fitting portion. A twist tie cut mechanism 7 is provided on the wing base 6b of the right wing portion 6R.

  Since the configuration of the left wing portion 6L is substantially the same as that of the right wing portion 6R, it will be briefly described. The release pin 6e of the left wing portion 6L is supported by a support plate 6d shown in FIG. The tension spring 6g urges the wing base 6b toward the wing closer 6c with the wing arm shaft 6k as a rotation axis.

  The left justification motor 6u of the left wing portion 6L drives the trapezoidal screw 6n to slide the wing closer 6c back and forth. When the wing closer 6c moves forward or backward, the wing claw 6a opens and closes the hole engaging pin 6s along the inclined long hole 6t with the wing arm shaft 6k as a rotation axis. The left justification motor 6u, the right justification motor 6h, and the trapezoidal screw 6n are examples of the drive unit.

  67A and 67B are perspective views showing an operation example of the wing claw 6a and the wing base 6b. The wing claws 6a of the right wing portion 6R and the left wing portion 6L shown in FIG. 67A are in an open state. From this state, the wing closer 6c is slid in the direction of the arrow V1 shown in FIG. 67B by the trapezoidal screw 6n shown in FIG. When the wing closer 6c is slid, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are closed as shown in FIG. 67B.

  The wing claw 6a includes a single groove 86n at the center. The width of the groove 86n is formed to be approximately the same as the line width of the twist tie 2. As shown in FIG. 67B, in a state where the wing claws 6a of the right wing portion 6R and the left wing portion 6L are closed, the groove portions 86n of the left and right wing claws 6a are aligned. The twist tie 2 is inserted into the groove 86n of the wing claw 6a.

  68A and 68B are side views showing an operation example of the wing claw 6a and the wing base 6b. The wing claws 6a of the right wing portion 6R and the left wing portion 6L shown in FIG. 68A are in an open state. In this state, the hole engaging pin 6s inserted into the left and right wing claws 6a is positioned at the uppermost position of the inclined long hole 6t. Moreover, the wing arm axis | shaft 6k which functions as a rotational axis of the wing nail | claw 6a is located in the front-end | tip of the horizontal long hole 6p.

  When the wing closer 6c is slid by the distance N2 in the direction of the arrow V1, the wing claws 6a of the right wing portion 6R and the left wing portion 6L rotate with the wing arm shaft 6k as a rotation axis as shown in FIG. 68B. Close. At this time, since the wing arm shaft 6k is fixed to the wing base 6b shown in FIG. 65, the position of the wing arm shaft 6k is constant as shown in FIGS. The attitude of the hole engaging pin 6s inserted into the main body is regulated by the inclined long hole 6t, and the wing claw 6a rotates about the wing arm shaft 6k as a rotation axis.

  In the state shown in FIG. 68B, the hole engaging pins 6s inserted into the left and right wing claws 6a are respectively located at the lowermost part of the inclined long hole 6t. Moreover, the wing arm axis | shaft 6k which functions as a rotational axis of the wing nail | claw 6a is located in the rear end of the horizontal long hole 6p. The total length of the horizontal long hole 6p corresponds to the distance N2 that the wing closer 6c moves.

  68B, when the wing closer 6c is slid by a distance N2 in the direction opposite to the arrow V1, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are engaged with holes as shown in FIG. 68A. The posture of the pin 6s is regulated by the inclined long hole 6t, and the pin 6s is rotated and opened with the wing arm shaft 6k as a rotation shaft.

  Next, a mechanism for driving the wing closer 6c of the twist tie set mechanism 6 will be described. FIG. 69A is a perspective view showing a configuration example of a drive mechanism of the wing closer 6c of the right wing portion 6R. A nut 6x is screwed onto the trapezoidal screw 6n shown in FIG. 69A. A connecting plate 6y is coupled to the nut 6x. The connecting plate 6y is formed in a concave shape and has screw holes 86b at four locations. In these screw holes 86b, four screw holes 86c of the wing closer 6c of the right wing portion 6R shown in FIG. 67A are aligned and coupled by screws. The connecting plate 6y is assembled with the bottom plate 86d interposed therebetween. Thereby, the connecting plate 6y moves in parallel along the bottom plate 86d while maintaining the posture.

  The trapezoidal screw 6n transmits the power of the right-justified motor 6h through the drive gear 86a and the motor gear 6z. In this example, the right alignment motor 6h increases the torque by the speed reduction mechanism 6w and transmits power to the trapezoidal screw 6n. When the nut 6x and the connecting plate 6y are translated by the trapezoidal screw 6n to the position of the connecting plate 6y shown in FIG. 69A, the wing claw 6a of the wing closer 6c of the right wing portion 6R is in the open state shown in FIG. 67A.

  FIG. 69B is a perspective view showing an operation example of the drive mechanism of the wing closer 6c of the right wing portion 6R. The nut 6x and the connecting plate 6y shown in FIG. 69B are translated while maintaining the posture along the bottom plate 86d by the rotation of the trapezoidal screw 6n. When the nut 6x and the connecting plate 6y are translated by the trapezoidal screw 6n to the position of the connecting plate 6y shown in FIG. 69B, the wing claws 6a of the wing closer 6c of the right wing portion 6R are in the closed state shown in FIG. 67B.

  FIG. 70A is a perspective view showing a configuration example of a drive mechanism of the wing closer 6c of the left wing portion 6L. A nut 86f is screwed into the trapezoidal screw 6n shown in FIG. 70A. A coupling plate 86g is coupled to the nut 86f. This connecting plate 86g has four screw holes 86i. In these screw holes 86i, four screw holes 86k of the wing closer 6c shown in FIG. 67A are aligned and coupled by screws. The connecting plate 86g is formed in a concave shape and is assembled with a square plate 86h interposed therebetween. As a result, the connecting plate 86g moves in parallel with its posture being regulated by the square plate 86h.

  The power of the left justification motor 6u is transmitted to the trapezoidal screw 6n through a coupling 86j that functions as a shaft coupling. In this example, the left justifying motor 6u increases the torque by the speed reduction mechanism 86e and transmits power to the trapezoidal screw 6n. When the nut 86f and the connecting plate 86g are translated by the trapezoidal screw 6n to the position of the connecting plate 86g shown in FIG. 70A, the wing claw 6a of the wing closer 6c of the left wing portion 6L is in the closed state shown in FIG. 67B.

  FIG. 70B is a perspective view showing an operation example of the drive mechanism of the wing closer 6c of the left wing portion 6L. The nut 86f and the connection plate 86g shown in FIG. 70B are translated in parallel by the rotation of the trapezoidal screw 6n and the posture is regulated by the square plate 86h. When the nut 86f and the connecting plate 86g are translated by the trapezoidal screw 6n to the position of the connecting plate 86g shown in FIG. 70B, the wing claw 6a of the wing closer 6c of the left wing portion 6L is in the open state shown in FIG. 67A.

  Next, an operation example in which the twist tie 2 is inserted into the tag 10 and bound together will be described. FIG. 71A shows a state in which the tag 10 is transported to the curl guide 45 by the tag transport mechanism 4 shown in FIG. At this time, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are in an open state. In the wing base 6b, a release pin 6e is supported by a support plate 6d shown in FIG. For this reason, the rear end of the wing base 6b is lifted with the wing arm shaft 6k as a rotation shaft.

  FIG. 71B shows a state where the tag 10 is pressed by closing the wing claws 6a of the right wing portion 6R and the left wing portion 6L. In this example, the right alignment motor 6h and the trapezoidal screw 6n shown in FIG. 69B move the wing closer 6c of the right wing portion 6R in the direction of the arrow V1 shown in FIG. Accordingly, the posture of the wing claw 6a of the right wing portion 6R is regulated by the hole engaging pin 6s and the inclined elongated hole 6t, and is rotated and closed with the wing arm shaft 6k as the rotation axis. At this time, the wing claw 6a presses one side of the mounting portion 10c of the tag 10 into the convex portion 45a (see FIG. 76) of the curl guide 45.

  The left justification motor 6u and trapezoidal screw 6n shown in FIG. 70B move the wing closer 6c of the left wing portion 6L in the direction of the arrow V1 shown in FIG. Accordingly, the posture of the wing claw 6a of the left wing portion 6L is regulated by the hole engaging pin 6s and the inclined elongated hole 6t, and is rotated and closed with the wing arm shaft 6k as the rotation axis. At this time, the wing claw 6a presses the other side of the mounting portion 10c of the tag 10 into the convex portion 45a (see FIG. 66) of the curl guide 45.

  In this way, the left and right wing claws 6a, 6a press the both ends of the mounting portion 10c of the tag 10 into the convex portions 45a of the curl guide 45, and form the mounting portion 10c into a substantially trapezoid shape. Therefore, the wing claws 6a and 6a can be formed into a shape that allows a substantially straight line to pass through the mounting holes 10d and 10d of the tag 10. In this state, the twist tie setting mechanism 6 inserts the twist tie 2 fed from the twist tie feeding mechanism 5 shown in FIG. 64 into the mounting holes 10d and 10d of the tag 10.

  The twist tie 2 includes a groove 86n of the wing claw 6a of the right wing 6R, one attachment hole 10d of the tag 10, a groove not shown of the curl guide 45, the other attachment hole 10d of the tag 10, and the left wing 6L. Passes in the order of the groove 86n of the wing claw 6a. Thereby, the twist tie 2 can be inserted into the mounting holes 10d, 10d of the tag 10.

  After inserting the twist tie 2, the twist tie setting mechanism 6 and the tag transport mechanism 4 are raised. 72 shows a state in which the twist tie set mechanism 6 and the tag transport mechanism 4 shown in FIG. 71B are raised with respect to the chassis plates 44a and 44b. Due to this rise, the release pin 6e of the twist tie set mechanism 6 shown in FIG. 72 is separated from the support plate 6d fixed to the chassis plate 44a. Further, the wing base 6b rotates about the wing arm shaft 6k as a rotation axis by the tension of the tension spring 6g.

  FIG. 73A is a cross-sectional view showing an operation example of the twist tie set mechanism 6. The position of the blade body 7a of the twist tie cut mechanism 7 provided on the wing base 6b is lowered by the rotation of the wing base 6b shown in FIG. 73A. At this time, the cutting edge 7g (see FIG. 77) of the blade body 7a located above the passage 86p of the twist tie 2 enters the passage 86p of the twist tie 2. The twist tie 2 inserted through the passage 86p is cut by the cutting edge 7g of the blade body 7a in the manner of push-off.

  The inner surface of the ceiling of the wing base 6b shown in FIG. 73A is in contact with the protruding piece 6v of the wing closer 6c. For this reason, the protruding piece 6v of the wing closer 6c is not fitted into the rectangular opening 6i of the wing base 6b.

  73B is a state in which the wing closer 6c is slid in the direction of the arrow V2. At this time, as described in FIG. 68, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are rotated and opened. When the wing claws 6a and 6a are opened, the wing claws 6a and 6a lift the twist tie 2. As a result, the twist tie 2 inserted through the groove 86n (see FIG. 67A) of the wing claw 6a is bent into a substantially V shape with the convex portion 45a of the curl guide 45 as the center. Further, by sliding the wing closer 6c in the direction of the arrow V2, the protruding piece 6v of the wing closer 6c is fitted into the rectangular opening 6i of the wing base 6b to fix the wing claw 6a and the wing closer 6c. Yes.

  In the twist tie set mechanism 6 shown in FIG. 73C, the wing closer 6c, to which the wing claw 6a opened by the wing base 6b is fixed, is slid in the direction of the arrow V3, thereby narrowing the distance between both ends of the twist tie 2.

  In this example, the rectangular opening 6i of the wing base 6b and the protruding piece 6v of the wing closer 6c are fitted. For this reason, the wing base 6b slides in the direction of the arrow V3 together with the sliding of the wing closer 6c.

  Further, since the wing base 6b slides, the wing claw 6a pivotally attached to the wing base 6b moves in the direction of the arrow V3 while being opened without rotating. Thus, since the wing base 6b fixes the wing closer 6c and the wing claw 6a, the wing claw 6a can be moved while the wing claw 6a is opened by sliding the wing closer 6c. Thereby, the twist tie 2 that is lifted up by the wing claw 6a of FIG. 73B and formed in a substantially V shape is formed in a substantially U shape with the convex portion 45a of the curl guide 45 as the center, as shown in FIG. 73C. The

  FIG. 74A is a side view showing an operation example of the twist tie twist mechanism 8. FIG. 74B is a perspective view showing an operation example of the twist tie twist mechanism 8. The twist tie twist mechanism 8 shown in FIGS. 74A and 74 includes an S-shaped member 8a and a shaft rod 8b. The shaft 8b is coupled to the center of the S-shaped member 8a. A pulley 8c shown in FIG. 1 is coupled to the shaft 8b, and a belt 8d is wound around the pulley 8c. The belt 8d is rotated by a torsion motor 87v (see FIG. 114).

  The twist tie twist mechanism 8 causes the S-shaped member 8a to stand by at the position shown in FIG. 74B. When the wing claw 6a forms the twist tie 2 into a U shape, both ends of the twist tie 2 are accommodated in the respective curved portions of the S-shaped member 8a. In this state, the twist tie twist mechanism 8 rotates the S-shaped member 8a by two and a half rotations. As a result, the twist tie 2 is twisted, and the twist tie can be fastened to the package 1 together with the tag 10.

  75A and 75B are cross-sectional views showing an operation example of the twist tie set mechanism 6. In the twist tie setting mechanism 6 shown in FIG. 75A, the twist tie 2 is twisted and fastened by the twist tie twist mechanism 8, and then the wing closer 6c having the wing claw 6a opened by the wing base 6b is fixed in the direction of the arrow V4. In this state, the gap between the wing claws 6a is widened by sliding.

  In this example, the rectangular opening 6i of the wing base 6b and the protruding piece 6v of the wing closer 6c are fitted. For this reason, the wing base 6b slides in the direction of the arrow V4 with the movement of the wing closer 6c.

  Further, since the wing base 6b slides, the wing claw 6a pivotally attached to the wing base 6b moves in the direction of the arrow V4 while being opened without rotating. As described above, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are separated from each other, so that the tag 10 can be extracted from between them.

  After the left and right wing claws 6a are separated, the twist-tie setting mechanism 6 shown in FIG. When the twist tie set mechanism 6 is lowered, the release pin 6e is supported by the support plate 6d shown in FIG. As a result, the wing base 6b rotates to the initial position around the wing arm shaft 6k. Accordingly, the protruding piece 6v of the wing closer 6c and the rectangular opening 6i of the wing base 6b are separated from each other. As a result, the twist tie set mechanism 6 returns to the initial state shown in FIGS.

  Thus, according to the tag attachment drive unit 101 according to the present invention, each of the wing claws 6a of the twist tie set mechanism 6 is rotated and closed by sliding of the wing closer 6c. Each of the wing claws 6a is three-dimensionally formed by pressing in the vicinity of each attachment hole 10d of the tag 10. Further, each of the wing claws 6 a is formed in a shape that allows a substantially straight line to pass through each mounting hole 10 d of the tag 10. The twist tie 2 fed out by the twist tie feed mechanism 5 is inserted through the groove 86n of the pair of wing claws 6a in the closed state and the mounting holes 10d of the tag 10.

  With this configuration, the mechanism for inserting the twist tie 2 into the tag 10 can be reduced in size, and the twist tie 2 can be reliably inserted into the mounting hole 10 d of the tag 10.

  Next, a configuration example of the twist tie cut mechanism 7 will be described. FIG. 76 is a perspective view illustrating a configuration example of a main part of the twist tie cut mechanism 7. The twist tie cut mechanism 7 shown in FIG. 76 includes a blade body 7a, a compression spring 7b, a shaft 7c, and a support member 7d. The blade body 7a is fixed to the support member 7d so as to be rotatable by a shaft 7c. The support member 7d is fixed to the wing base 6b.

  A compression spring 7b is attached to the rear end of the blade body 7a. The blade edge 7g (see FIG. 77) of the blade body 7a is set above the passage 86p of the twist tie 2 when the wing base 6b is lifted as shown in FIG.

  FIG. 77 is a perspective view showing a configuration example of the blade body 7a. The blade body 7a shown in FIG. 77 includes openings 7e and 7e and a blade edge 7g. The rear end 7f of the blade body 7a is biased by a compression spring 7b shown in FIG. A shaft 7c is inserted into the openings 7e and 7e, and rotates about a line segment KK indicated by a one-dot chain line. Thereby, the cutting edge 7g of the blade body 7a abuts above the passage 86p of the twist tie 2 shown in FIG.

  78A is a cross-sectional view showing an operation example (part 1) of the twist tie cut mechanism 7. FIG. The wing base 6b to which the blade body 7a shown in FIG. 78A is fixed is in a lifted state. At this time, the cutting edge 7 g of the blade body 7 a is set above the passage 86 p of the twist tie 2.

  FIG. 78B is a cross-sectional view showing an operation example (No. 2) of the twist tie cut mechanism 7. 78B shows a state in which the wing base 6b to which the blade body 7a is fixed is lowered. At this time, the cutting edge 7g of the blade body 7a enters the passage 86p of the twist tie 2 and cuts the twist tie 2 in the manner of push-off.

  The force for operating the blade body 7a is generated by the tension spring 6g. The tension spring 6g is located at a position away from the wing arm shaft 6k, which is the rotation shaft of the wing base 6b, and the blade body 7a is installed in the vicinity of the wing arm shaft 6k. For this reason, the tension of the tension spring 6g is amplified by the lever principle. Thereby, even if the tension | tensile_strength of the tension spring 6g is weak, the twist tie 2 can be reliably cut | disconnected by the blade main body 7a.

  Next, a configuration example of the ascending / descending mechanism 20 will be described. FIG. 79 is a perspective view illustrating a configuration example of the ascending / descending mechanism 20. 79 includes a vertical motor 20a, a trapezoidal screw 20b, a motor gear 20c, a reduction gear 20d, and a drive gear 20e. The motor gear 20c is coupled to the vertical motor 20a, and the drive gear 20e is coupled to the trapezoidal screw 20b. The motor gear 20c of the vertical motor 20a and the drive gear 20e of the trapezoidal screw 20b are meshed with the reduction gear 20d. Thereby, the power of the vertical motor 20a is amplified and transmitted to the trapezoidal screw 20b.

  FIG. 80 is a perspective view illustrating a configuration example of the ascending / descending mechanism 20. The ascending / descending mechanism 20 shown in FIG. 80 includes vertical guide rollers 20i and 20j. The vertical guide roller 20i is rotatably attached to the chassis plate 44a and is in contact with the surrounding plate 20k. The vertical guide roller 20j is rotatably attached to the chassis plate 44a and is in contact with the surrounding plate 20m. In addition, vertical guide rollers (not shown) are attached at positions facing the vertical guide rollers 20i and 20j. That is, a vertical guide roller is provided in contact with the four surfaces of the surrounding plate surrounding the tag transport mechanism 4 and the twist tie set mechanism 6 that are raised or lowered. These four vertical guide rollers correct the inclination so that the tag transport mechanism 4 and the twist tie set mechanism 6 that rise and fall rise and fall in the vertical direction with respect to the chassis plate 44a.

  FIG. 81A is a side view showing a configuration example of the ascending / descending mechanism 20. The tag transport mechanism 4 and the twist tie set mechanism 6 shown in FIG. 81A are in a lowered state (initial state). The ascending / descending mechanism 20 shown in FIG. 81A includes a trapezoidal screw 20b, a nut 20f, a frame pusher 20g, and a guide rod 20h. The nut 20f is screwed to the trapezoidal screw 20b. The frame pusher 20g is formed in a metal plate shape and is coupled to the nut 20f. Guide rods 20h are inserted into the four corners of the frame pusher 20g. A tag transport mechanism 4 and a twist tie set mechanism 6 are placed on the frame pusher 20g.

  FIG. 81B is a side view showing an operation example of the ascending / descending mechanism 20. The tag transport mechanism 4 and the twist tie set mechanism 6 shown in FIG. 81B are in a raised state. In this example, when the trapezoidal screw 20b is rotated, the frame pusher 20g coupled to the nut 20f is raised. At this time, the frame pusher 20g is guided by the guide rods 20h at the four corners and ascends while maintaining a horizontal state with respect to the chassis plates 44a and 44b. As a result, the tag transport mechanism 4 and the twist tie set mechanism 6 placed on the frame pusher 20g are also raised. At this time, the vertical guide rollers 20i, 20j, etc. shown in FIG. 80 abut against the surrounding plates 20k, 20m to correct the inclination of the tag transport mechanism 4 and the twist tie set mechanism 6 that rise or fall.

  The center of gravity of the tag transport mechanism 4 and the twist tie set mechanism 6 is the position J1, and the axis of the trapezoidal screw 20b is set to the position J2. As described above, since the offset occurs between the position J1 and the position J2, the inclination of the tag transport mechanism 4 and the twist tie set mechanism 6 is corrected by the vertical guide rollers 20i and 20j.

  When the trapezoidal screw 20b is rotated in the direction opposite to the upward direction, the frame pusher 20g descends while maintaining a horizontal state with respect to the chassis plates 44a and 44b. As a result, the tag transport mechanism 4 and the twist tie set mechanism 6 placed on the frame pusher 20g are also lowered.

  Next, a configuration example of the cartridge 17 will be described. 82A and 82B are perspective views showing an example of mounting the cartridge 17. The cartridge 17 is attached to the tag attachment drive unit 101. In the tag attachment drive unit 101 shown in FIG. 82A, the cartridge 17 is mounted on the cartridge set portion 26 of the apparatus main body. In the tag attachment drive unit 101 shown in FIG. 82B, the cartridge 17 is removed from the cartridge setting unit 26.

  The cartridge 17 is pushed into the cartridge setting unit 26. Thereafter, when the handle 26a of the cartridge setting portion 26 is pulled, the release lever 26b slides. When the release lever 26b slides, the pusher lock mechanism 17m (see FIG. 84B) of the cartridge 17 is released, and the cartridge 17 is fixed to the cartridge set portion 26.

  FIG. 83 is a perspective view showing a configuration example of the cartridge 17. FIG. 84A is a top view showing a configuration example of the cartridge 17. FIG. 84B is a rear view showing a configuration example of the cartridge 17. The cartridge 17 includes a guide rod 17b, a pusher 17c, width adjusting plates 17d and 17d ', width adjusting portions 17e and 17e', wheels 17h and a gripping portion 17i.

  Only two guide rods 17 b are provided upright on the bottom surface 17 k of the cartridge 17. These guide rods 17 b are inserted into the mounting holes 10 d of the tag 10, and the tag 10 is loaded into the cartridge 17.

  The pusher 17c is attached so as to be movable up and down, and pushes up the tag 10 in which the attachment hole 10d is attached to the guide rod 17b. In this example, the pusher 17c is provided with vertical bearings 17r at four corners. These vertical bearings 17r are mounted on four pusher shafts 17g. A compression spring 17 f is provided between the vertical bearing 17 r of the pusher 17 c and the bottom surface 17 k of the cartridge 17. These compression springs 17f are attached to the four pusher shafts 17g and urge the pushers 17c. The pusher 17c is locked to the bottom surface 17k side of the cartridge 17 by a pusher lock mechanism 17m shown in FIG. 84B.

  Alignment plates 17d and 17d 'are arranged at both ends of the pusher 17c. The width aligning plate 17d and the width aligning plate 17d 'move separately. For example, the width adjusting plate 17d moves in the direction of the arrow M2 by rotating the width adjusting portion 17e. The width adjusting plate 17d 'moves in the direction of the arrow M2 by rotating the width adjusting portion 17e' shown in FIG. 84A. As a result, even if the shape of the tag is not symmetrical, the tag can be securely sandwiched and held by moving the width adjusting plates 17d and 17d 'separately to reduce the width of the tag.

  As shown in FIG. 84A, two wheels 17h are rotatably attached to both side surfaces of the housing 17u of the cartridge 17. These wheels 17h are attached to rails 26c and 26c at both ends shown in FIG. A gripping portion 17 i is attached to the back surface of the housing 17 u of the cartridge 17. The operator attaches the cartridge 17 to the cartridge setting portion 26 with the gripping portion 17 i.

  FIG. 85 is a perspective view showing an example of the function of the cartridge 17. FIG. 86A is a top view illustrating a function example of the cartridge 17. FIG. 86B is a rear view showing a function example of the cartridge 17.

  The guide rods 17b and 17b are inserted into the mounting holes 10d and 10d of the tag 10, and a plurality of tags 10 are stacked on the pusher 17c and loaded into the cartridge 17. At this time, the pusher 17c is locked to the bottom surface 17k side of the cartridge 17 by the pusher lock mechanism 17m shown in FIG. 86B.

  By rotating the width adjusting portion 17e, the width adjusting plate 17d is brought close to the tag 10 and is brought into contact with the information presenting portion 10a of the tag 10. Similarly, by rotating the width adjusting portion 17e ′ shown in FIG. 86B, the width adjusting plate 17d ′ is brought close to the tag 10 and brought into contact with the information presenting portion 10a of the tag 10 to align the tag 10. ing. In this state, the cartridge 17 is mounted on the cartridge setting unit 26 with the gripping portion 17i.

  FIG. 87 is a perspective view showing a configuration example of the pusher 17c and the guide rod 17b. FIG. 88 is a side view showing a configuration example of the pusher 17c and the guide rod 17b. FIG. 89 is a rear view showing a configuration example of the pusher 17c and the guide rod 17b and viewed from the tag delivery direction U. The pusher 17c shown in FIG. 87 includes an H-shaped plate 17q and an I-shaped plate 17p. The I-shaped plate 17p is coupled to the H-shaped plate 17q. The combined plates 17p and 17q have a through hole 17s at the same position. A guide rod 17b is inserted into these through holes 17s.

  The guide rod 17b is erected on the block 17t. The block 17t is fixed to the housing 17u of the cartridge 17. The distal end of the guide rod 17b is formed in a tapered shape, and has a slope portion 17n formed by chamfering only two surfaces with a difference of about 90 ° to form a slope. The slope portions 17n and 17n are arranged so that the apexes thereof are substantially at the center of the mounting hole 10d of the tag 10 (see FIG. 86A). This makes it easy to attach the mounting hole 10d to the guide rod 17b without the inclined surface portion 17n at the front end striking the edge of the mounting hole 10d of the tag 10.

  Further, the slope portions 17n and 17n are provided so that one slope 17v faces the feed direction U of the tag 10. When the tag 10 is transported in the feed-out direction U and comes into contact with the slope portion 17n, the tag 10 is fed out by sliding on the slope 17v of the slope portion 17n. Thereby, for example, when two tags 10 are overlapped and sent out from the cartridge 17, only the uppermost tag 10 is slid out on the slope 17v of the slope portion 17n, and the second tag 10 is placed on the slope portion 17n. It is locked by the slope 17v.

  Next, an example of the function of the guide rod 17b will be described. FIG. 90 is a top view showing an example of the function of the guide rod 17b. The guide rod 17b shown in FIG. 90 is inserted through the mounting hole 10d of the tag 10. As shown in FIG. 90, when mounting the mounting hole 10d of the tag 10 to the guide rod 17b, even if the center of the mounting hole 10d deviates from the top of the guide rod 17b, the top of the guide rod 17b is the region of the mounting hole 10d. The mounting hole 10d can be attached to the guide rod 17b. Thereby, work time can be shortened. Moreover, if the tag 10 passes through the inclined surface portion 17n that is the tip (vertex) of the guide rod 17b, the position and posture of the tag 10 are regulated by the main body of the guide rod 17b as shown in FIG. 86A.

  Thus, since the guide rod 17b shown in FIG. 90 only needs to be inserted into the mounting hole 10d of the tag 10, the degree of freedom when the tag 10 is attached is high, and the tag 10 can be easily attached to the cartridge 17.

  Next, the pusher lock mechanism 17m of the cartridge 17 will be described. 91 is a cross-sectional view taken along the line H4-H4 in FIG. 84A showing a configuration example of the pusher lock mechanism 17m of the cartridge 17. FIG. The pusher lock mechanism 17m shown in FIG. 91 holds the pusher 17c biased by the compression spring 17f. The pusher lock mechanism 17m includes a lock claw 17w, a tension spring 48b, and a switch plate 48f.

  The lock claw 17w is fixed to the holder 48g so as to be rotatable by a rotation shaft 17y. A cartridge switch shaft 17x is mounted in the long hole 48e of the lock claw 17w. The cartridge switch shaft 17x is fixed to the switch plate 48f. The switch plate 48f is engaged with the lock claw 17w and is slidably attached to the housing 17u.

  The tension spring 48b is an example of an urging member, and one end is fixed to the cartridge switch shaft 17x and the other end is fixed to the holder 48g to pull the cartridge switch shaft 17x toward the holder 48g. Thereby, the basic posture of the lock claw 17w becomes the state shown in FIG.

  A holder 48a is attached to the plate 17q of the pusher 17c. A pusher lock shaft 17z, which is an example of a lock shaft member, is fixed to the holder 48a. A tip 48h of the lock claw 17w formed in a hook shape is provided so as to be able to be engaged with the pusher lock shaft 17z. The tension spring 48b urges the lock claw 17w to lock the lock claw 17w to the pusher lock shaft 17z. Accordingly, the pusher lock mechanism 17m can lock the pusher 17c to the bottom surface 17k side of the cartridge 17.

  When the lock of the pusher 17c is released, the switch claw 17w is slid in the direction of the arrow M3 which is the direction opposite to the urging direction of the tension spring 48b. As a result, the cartridge switch shaft 17x fixed to the switch plate 48f slides, the lock claw 17w rotates about the rotation shaft 17y, and the direction of the long hole 48e of the lock claw 17w becomes substantially horizontal. Accordingly, the pusher lock shaft 17z is released from the hook-shaped tip 48h of the lock claw 17w. Thereby, the lock of the pusher 17c is released, and the pusher 17c is raised by the urging force of the compression spring 17f.

  FIG. 92 is a perspective view of the bottom surface side showing the configuration example of the cartridge 17. An opening 48k and a long hole 48j are provided in the bottom surface 17k of the cartridge 17 shown in FIG. This opening 48k is for ensuring the rotation range of the lock claw 17w. A switch plate 48f protrudes from the long hole 48j. The switch plate 48f is slid in the direction of the arrow M3 when the release lever 26b shown in FIG. As a result, the pusher 17c is unlocked as described with reference to FIG. 91, and the pusher 17c is raised by the urging force of the compression spring 17f.

  A cartridge base 48 i is attached to the bottom surface 17 k of the cartridge 17. The cartridge base 48i is used for removing the cartridge 17 from the cartridge setting section 26 for the purpose of loading the tag 10 into the cartridge 17 and temporarily placing the cartridge 17 on a suitable desk or the like. And a gap between the cartridge 17 and the placement surface of the cartridge 17 for temporary placement. As a result, the switch plate 48f and the lock claw 17w protruding from the bottom surface 17k of the cartridge 17 do not come into contact with the placement surface of the cartridge 17 where the cartridge 17 is temporarily placed.

  FIG. 93A is a perspective view showing a configuration example of the plate 17q of the pusher 17c. FIG. 93B is a top view showing a configuration example of the plate 17q of the pusher 17c. The plate 17q has notches 48m and 48m at the tip. When the pusher 17c is unlocked, the notches 48m and 48m are an example of a fitting portion, and are fitted to an L-shaped sheet metal 26e shown in FIG. This sheet metal 26e is an example of a retaining member.

  FIG. 94 is a perspective view illustrating a configuration example of a main part of the cartridge setting unit 26. 95A and 95B are a perspective view and a side view showing a function example (No. 1) of a main part of the cartridge setting unit 26. FIG. 96A and 96B are a perspective view and a side view showing a function example (No. 2) of a main part of the cartridge setting unit 26. FIG.

  The wheels 17h of the cartridge 17 shown in FIG. 92 are mounted on the rails 26c at both ends of the cartridge setting portion 26 shown in FIG. 94, and the cartridge 17 is pushed into the cartridge setting portion 26. If the handle 26a is pulled while the cartridge 17 is completely pushed into the cartridge setting portion 26, the release lever 26b slides. The release lever 26b is slid to slide the switch plate 48f shown in FIG.

  As a result, as described with reference to FIG. 91, the lock claw 17w rotates and the pusher 17c is unlocked. When the lock of the pusher 17c is released, the plate 17q of the pusher 17c is raised by the urging force of the compression spring 17f as shown in FIGS. 95A and B and FIGS. 96A and 96B. At this time, the notch 48m of the plate 17q of the pusher 17c shown in FIGS. 96A and 96B can be fitted into the L-shaped metal plate 26e to prevent the pusher 17c from coming off. Therefore, the cartridge 17 can be mounted so as not to be detached from the cartridge setting portion 26 of the tag mounting drive unit 101. The tag 10 stacked and loaded on the cartridge 17 is pushed up by the pusher 17c, and the uppermost tag 10 comes into contact with the pickup roller 39a (see FIG. 51). Thus, the lock of the pusher 17c is released by the release lever 26b on the apparatus main body side, so that the lock of the pusher 17c is erroneously released when the cartridge 17 is removed from the apparatus main body, that is, when the cartridge 17 is in a single state. Less likely.

  A magnet (not shown) is provided on the front surface of the cartridge 17, and a magnet (not shown) is provided at a position corresponding to the front panel 26 d of the cartridge setting unit 26. As a result, when the cartridge 17 is pushed into the cartridge setting portion 26, the cartridge 17 is attracted to the front panel 26d of the cartridge setting portion 26 by magnetic force, so that the timing for releasing the lock of the pusher 17c becomes clear. Of course, a magnet may be provided on only one of the front surface of the cartridge 17 and the front panel 26d of the cartridge setting portion 26.

  As described above, according to the tag mounting drive unit 101 of the present invention, the notch 48m of the pusher 17c urged by the compression spring 17f when the pusher lock mechanism 17m of the cartridge 17 is released is used as the sheet metal of the cartridge set unit 26. 26e to prevent the pusher 17c from coming off.

  With this configuration, it is possible to prevent the cartridge 17 from being removed from the apparatus main body when the pusher 17c is unlocked. Accordingly, it is possible to prevent the cartridge from being accidentally detached from the apparatus main body in a state where the pusher member is unlocked, and to prevent the tag from jumping out of the cartridge and being scattered by the urging force of the pusher member. Therefore, it is possible to prevent the tag from falling and soiling the tag.

  Next, guide rods 84a to 84c in other embodiments to be mounted in the mounting hole 10d of the tag 10 will be described. FIG. 97A is a side view showing a configuration example of the guide rod 84a. FIG. 97B is an enlarged view of the tip of the guide rod 84a. The tip of the guide rod 84a shown in FIG. 97B has a conical portion 85a formed in a conical shape. The tip is inserted into the mounting hole 10d of the tag 10 from the conical portion 85a.

  FIG. 98A is a side view showing a configuration example of the guide rod 84b. FIG. 98B is an enlarged view of the tip of the guide rod 84b. The tip of the guide rod 84b shown in FIG. 98B has a semicircular portion 85b formed in a semicircular shape. The semicircular portion 85b at the tip is inserted into the mounting hole 10d of the tag 10.

  FIG. 99A is a side view showing a configuration example of the guide rod 84c. FIG. 99B is an enlarged view of the tip of the guide rod 84c. The tip of the guide rod 84c shown in FIG. 99B has a trapezoidal portion 85c having a trapezoidal cross-sectional shape. The trapezoidal portion 85c at the tip is inserted into the mounting hole 10d of the tag 10. As described above, the guide rod to which the tag 10 is attached may have a shape in which the tip of the guide rod is formed thin as shown in the guide rods 84a to 84c.

  Subsequently, a configuration example of another cartridge 17B will be described. 100A and 100B are perspective views showing a configuration example of a main part of another cartridge 17B. In the cartridge 17B shown in FIG. 100A, a guide rod 84d is detachably provided on the block 17t '. The two guide rods 84d are fixed to the connector 48c.

The connector 48c of the guide rod 84d is inserted into the opening 48d and fixed as shown in FIG. 100B.

  101A and 101B are perspective views showing an example of use of the main part of the cartridge 17B. When stacking and loading the tag 10 on the cartridge 17B, first, as shown in FIG. 101A, the connector 48 of the guide rod 84d of the cartridge 17B is pulled out from the opening 48d such as the block 17t 'and removed.

  Next, as shown in FIG. 101B, the guide rod 84d is inserted into the mounting hole 10d of the tag 10 and attached. Then, the connector 48c of the guide rod 84d to which the tag 10 is attached is attached to the opening 48d including the block 17t '. Thereby, the tag 10 can be attached to the cartridge 17B.

  As described above, the guide rod 84d once removed can be inserted into the mounting hole 10d of the tag 10 and mounted in the block 17t 'of the cartridge 17B in this state. Therefore, the guide rod 84d can be freely moved as compared with the fixed guide rod 17b shown in FIG. 87, so that the guide rod 84d can be easily mounted in the mounting hole 10d of the tag 10.

  Next, a configuration example of the twist tie feed mechanism 5 will be described. FIG. 102 is a perspective view showing a configuration example of the twist tie feed mechanism 5. FIG. 103A is a side view showing a configuration example of the twist tie feed mechanism 5. FIG. 103B is a rear view showing a configuration example of the twist tie feed mechanism 5. The twist tie feed mechanism 5 is wound around the bobbin 58 shown in FIG. 1 and pulls out the twist tie 2 and supplies it to the twist tie set mechanism 6.

  The twist tie feed mechanism 5 includes a twist tie feed motor 5a, a guide roller 5b, and a toggle clamp mechanism 5c. A stepping motor is used as the twist tie feed motor 5a, and functions as a drive source for feeding the twist tie 2. The guide roller 5b is attached to the holder 5h while being supported by the shaft 5g. The guide roller 5b guides the twist tie 2 and keeps the entry direction of the twist tie 2 constant. The toggle clamp mechanism 5c is an example of a clamp mechanism having a boosting function, and the twist tie 2 drawn from the guide roller 5b is fed to a feed knurl 5m via a compression spring 5f which is an example of an elastic member or an urging member. Crimp or release crimp.

  FIG. 104A is a side view showing an example of the internal configuration of the twist tie feed mechanism 5. FIG. 104B is a rear view showing an example of the internal configuration of the twist tie feed mechanism 5. In FIGS. 104A and 104B, the sheet metal 5d shown in FIGS. 103A and 103B is removed. 104A and 104B show a state where the toggle clamp mechanism 5c is clamping.

  The toggle clamp mechanism 5c includes an operation unit 5j, a link member 5x, and a spring seat 5i. The fulcrum of the operation unit 5j is pivotally attached to the holder 5z by a pin 5r which is an example of a first shaft member. The operating point of the operation portion 5j is pivotally connected to one end of the curved link member 5x by a pin 5s which is an example of a second shaft member. The other end of the link member 5x is rotatably connected to a rod 49a extending from a spring seat 5i that is an example of a support base. The rod 49a is supported by the clamp guide 5y so as to be movable up and down.

  The lever 5q that engages with the compression spring 5f is pivotally attached to the sheet metal 49b by a shaft 5v. A feed roller 5k, which is an example of a driven roller, is attached to the lever 5q by a shaft 5u. A compression spring 5f is interposed between the spring seat 5i and the lever 5q, and the spring seat 5i supports the compression spring 5f. The compression spring 5f biases one end of the lever 5q to rotate the lever 5q about the shaft 5v, and presses the feed roller 5k against the feed knurl 5m. The feed knurl 5m is an example of a drive roller, and is pivotally attached to the sheet metal 49b by a shaft 5w.

  A roller 5n is fixed to the drive shaft 49c of the twist tie feed motor 5a. The roller 5n and the feed knurl 5m are drivingly connected by a belt 5p. Thereby, the driving force of the twist tie feed motor 5a is transmitted to the feed knurl 5m, and the feed knurl 5m rotates around the shaft 5w.

  The twist tie 2 drawn from the guide roller 5b is sandwiched between the feed knurl 5m and the feed roller 5k in contact with the feed knurl 5m and the feed roller 5k. In a state where the feed knurl 5m and the feed roller 5k cooperate to sandwich the twist tie 2, the feed knurl 5m rotates to rotate the feed roller 5k and pull out the twist tie 2.

  FIG. 105A is a side view showing an operation example of the twist tie feed mechanism 5. FIG. 105B is a rear view showing an operation example of the twist tie feed mechanism 5. 105A and 105B show a state where the toggle clamp mechanism 5c is released from the clamp. In this example, the operation portion 5j of the toggle clamp mechanism 5c is pulled down, and the operation portion 5j is rotated about 180 ° around the pin 5r. By rotating the operation portion 5j, the link member 5x is bent and extended, and the spring seat 5i and the compression spring 5f are lowered. When the compression spring 5f is lowered, the lever 5q biased by the compression spring 5f is rotated about the shaft 5v by its own weight as shown in FIG. 105A. By the rotation of the lever 5q, the feed roller 5k attached to the lever 5q is separated from the feed knurl 5m. This creates a gap between the feed knurl 5m and the feed roller 5k. In this state, with both hands, the operator inserts the twist tie 2 drawn from the guide roller 5b through the insertion port 49e into the gap between the feed knurl 5m and the feed roller 5k.

  After the insertion, the operation portion 5j is pulled up to the position shown in FIGS. 104A and 104B, and the twist tie 2 is sandwiched between the feed knurl 5m and the feed roller 5k. When the feed knurl 5m rotates with the twist tie 2 sandwiched between the feed knurl 5m and the feed roller 5k, the feed roller 5k also rotates and the twist tie 2 is pulled out.

  FIG. 106 is a perspective view showing a configuration example of the feed roller 5k and the feed knurl 5m. The feed knurl 5m shown in FIG. 106 is formed from a metal material. The outer peripheral surface of the feed knurl 5m is composed of a groove portion 49d and a flat portion 49g. The groove 49d is provided at the center along the outer peripheral surface of the feed knurl 5m. A thin wire 2a as a core wire of the twist tie 2 shown in FIG. 50 is fitted into the groove portion 49d.

  The flat surface portions 49g are provided at both ends of the groove portion 49d, and are provided with anti-slip shapes such as a vertical shape and a cross shape. The flat portion of the covering material 2b of the twist tie 2 shown in FIG. 50 is aligned with the flat portion 49g.

  The feed roller 5k is molded from a rubber material and is pivotally attached to the lever 5q by a shaft 5u. When the twist tie 2 is sandwiched between the feed roller 5k and the feed knurl 5m, the fine wire 2a of the twist tie 2 can be released to the groove 49d. Accordingly, since a force is evenly applied to the twist tie 2, it is possible to prevent the covering material 2b of the twist tie 2 from being broken by roller friction. If the groove 49d is not provided, roller friction concentrates on the covering material 2b in the portion of the thin wire 2a, so that the covering material 2b in the portion of the thin wire 2a may be broken.

  107A and 107B are schematic views showing an example of the length of the compression spring 5f. The compression spring 5f shown in FIG. 107A is attached to the spring shaft 49f of the lever 5q and the spring seat 5i. The compression spring 5f shown in FIG. 107A is a state where the toggle clamp mechanism 5c is clamped and compressed.

When the height of the spring shaft 49f is E1, the height of the spring seat 5i is E2, and the height of the compression spring 5f at the maximum compression is LM, the relationship expressed by the following formula (1) is satisfied. . Thereby, the compression spring 5f can be contracted to the height LM without the spring shaft 49f and the spring seat 5i colliding with each other.
LM> E1 + E2 (1)

  If the relationship of the expression (1) is not satisfied, that is, if the sum of the height E1 of the spring shaft 49f and the height E2 of the spring seat 5i is higher than the height LM of the compression spring 5f during maximum compression, The shaft 49f and the spring seat 5i collide, and the compression spring 5f cannot be reduced to the height LM.

The compression spring 5f shown in FIG. 107B is in a state where the toggle clamp mechanism 5c is released from the clamp and extended. When the free length of the compression spring 5f is L and the attachment length of the compression spring 5f is LS, the relationship shown in the following formula (2) is satisfied. Thereby, the compression spring 5f does not come off from the spring shaft 49f and the spring seat 5i when the clamp is released.
L> LS-E1 (2)

  If the relationship of Expression (2) is not satisfied, that is, if the free length L of the compression spring 5f is shorter than the length obtained by subtracting the height E1 of the spring shaft 49f from the attachment length LS of the compression spring 5f, the compression spring 5f comes off the spring shaft 49f and the spring seat 5i.

  As described above, the tag mounting drive unit 101 according to the present invention has the feed roller 5k that sandwiches the twist tie 2 in cooperation with the feed knurl 5m, and the toggle clamp mechanism 5c of the twist tie feed mechanism 5 By moving up and down a spring seat 5i that supports a compression spring 5f that urges the roller 5k, the feed roller 5k is brought into contact with or separated from the feed knurl 5m through the compression spring 5f.

  With this configuration, it is possible to prevent the urging force of the compression spring 5f from acting on the feed roller 5k when the clamp of the toggle clamp mechanism 5c is released. Thereby, a gap is formed between the feed roller 5k and the feed knurl 5m in a state where no force is applied. Therefore, since the operator can insert the twist tie 2 into the gap using both hands, the operability in inserting the twist tie 2 can be improved. Further, since the toggle mechanism is used, operation with a small force is possible, and the apparatus can be miniaturized.

  Next, a shearing cutter 82 that cuts the tip of the twist tie 2 pulled out from the bobbin 58 will be described. FIG. 108 is a perspective view showing a configuration example of the shearing cutter 82. 108, when the tip of the twist tie 2 pulled out from the bobbin 58 is bent, the bent portion of the twist tie 2 is cut and removed.

  The cutter 82 is attached to the chassis plate 44 b of the tag attachment drive unit 101. The attachment position of the cutter 82 is in the vicinity of the twist tie feed mechanism 5. For example, when a binding failure of the twist tie 2 occurs, the bent portion of the twist tie 2 is sheared by the cutter 82 and removed. Then, the remaining straight twist tie 2 is inserted into the twist tie feed mechanism 5. As a result, the straight twist tie 2 can be inserted into the tag mounting drive unit 101 with a simple configuration.

  FIG. 109A is an enlarged view showing a configuration example of the shearing cutter 82. The cutter 82 shown in FIG. 109A includes a mounting table 82a, a shearing lower plate 82b, and a shearing upper plate 82c. The lower plate 82b and the upper plate 82c are formed by cutting one plate.

  FIG. 109B is an enlarged view showing an operation example of the shearing cutter 82. In the cutter 82 shown in FIG. 109B, the upper plate 82c is pressed toward the lower plate 82b. Thereby, the twist tie 2 sandwiched between the upper plate 82c and the lower plate 82b can be sheared. Therefore, for example, when a binding failure of the twist tie 2 occurs, the bent portion of the twist tie 2 can be easily removed by shearing with the cutter 82.

  Subsequently, a method of shearing the twist tie 2 by another method will be described. FIG. 110 is a perspective view illustrating a configuration example of the shearing mechanism 83c. FIG. 111A is a cross-sectional view illustrating a configuration example of the shearing mechanism 83c. FIG. 111B is an enlarged view within a broken-line square in FIG. 111A.

  FIG. 112 shows a state in which the operation portion 5j of the toggle clamp mechanism 5c is slightly pulled up with the twist tie 2 inserted through the slits 83a and 83b shown in FIG. At this time, the rod 49a 'moves up as described with reference to FIGS. 104A and 105A. As shown in FIG. 113B, the twist tie 2 is sheared by the slit 83a functioning as a cutter blade and the clamp guide 5y 'functioning as a cutter receiver as the rod 49a' rises.

In the time chart of this embodiment, when the package 1 is inserted into the bag insertion port viewed from the bag insertion direction I, and the start switch 90 is turned on at time t1 in the time scale shown in FIGS. 116A and 117A, The control unit 87a receives the switch-on signal SS9 from the operation unit 87z and starts operation.

  The control unit 87a outputs a process execution signal SS87a to the control unit 50 of the fan forming drive unit 40 and outputs a process execution signal SS87b to the path system of the tag mounting drive unit 101 at time t2 shown in FIGS.

  When the path control unit 88a receives this processing execution signal SS87b, at the time t3 shown in FIGS. 117B and E, the motor control signals S88c and S88d cause the left justification motor 6u and the right justification motor 6h to move in the CCW (counterclockwise) direction. Rotate. When the left justification motor 6u and the right justification motor 6h rotate CCW, the wing claw 6a is closed as shown in FIG. 73A.

  At time t4 shown in FIG. 117D, the control unit 88a inputs a left-justified motor end detection signal S88h of “H” level from the left-justified motor end sensor 88h, and stops driving the left-justified motor 6u. Further, the control unit 88a inputs the right-aligned motor end detection signal S88j of “H” level from the right-aligned motor end sensor 88j at time t4 shown in FIG. 117G, stops driving the right-aligned motor 6h, and outputs a path preparation completion signal SS88. Output to the transport control unit 87a.

  Further, the path control unit 88a moves the shutter motor 88e in the CCW direction by, for example, 500 steps by the motor control signal S88b at time t5 shown in FIG. 117H after 400 ms has elapsed from time t4 when the path preparation completion signal SS88 was output. Rotate. When the shutter motor 88e rotates CCW, a shutter plate of a shutter mechanism 89 (not shown) provided between the mounting table 81a and the mounting table 81b shown in FIG. 1 opens.

  The transport system control unit 87a receives the path preparation completion signal SS88 from the path system control unit 88a, and then, at time t5 shown in FIG. 116I, the twist tie feed motor 5a is moved in the CW (clockwise) direction by the motor control signal S87d, for example 470. Drive only steps. When the twist tie feed motor 5 a rotates, the twist tie feed mechanism 5 shown in FIG. 102 operates to pull out the twist tie 2 from the bobbin 58.

  The control unit 87a inputs the tag attachment request signal S41 from the control unit 50 of the bag mouth fan drive unit 40 when the twist tie 2 is completely pulled out from the bobbin 58. Thereafter, at time t7 shown in FIG. 116J, the control unit 87a drives the vertical motor 20a in the CCW direction by the motor control signal S87f. When the vertical motor 20a rotates, as shown in FIG. 81B, the ascending / descending mechanism 20 operates to raise the tag transport mechanism 4 and the twist tie set mechanism 6.

  The control unit 87a receives the “H” level vertical motor end detection signal S87u from the vertical motor end sensor 87u at time t10 shown in FIG. 116L, and stops driving the vertical motor 20a.

  At this time, the control unit 87a drives the twist tie feed motor 5a, for example, 100 steps in the CCW direction, for example, 200 ms after driving the vertical motor 20a shown in FIG. 116J in the CCW direction. Thereby, the twist tie feed mechanism 5 shown in FIG. 102 operates to pull back the twist tie 2. This is to prevent the twist tie 2 sent out to the twist tie set mechanism 6 from being deformed when the twist tie set mechanism 6 is lowered because the twist tie feed mechanism 5 is not raised and lowered. In this way, the twist tie 2 is pulled back as the twist tie set mechanism 6 is lowered.

  When the control unit 87a inputs the “H” level vertical motor end detection signal S87u indicating the lowering of the twist tie set mechanism 6 at time t10 shown in FIG. 116L, the control unit 87a outputs the processing execution signal SS87b to the path system control unit 88a. To do.

  When this processing execution signal SS87b is input, the control unit 88a drives the left-justified motor 6u in the CW direction by a motor control signal S88c at time t11 shown in FIG. 117B. Also, the right justifying motor 6h is driven in the CW direction by the motor control signal S88d at time t11 shown in FIG. 117E. When the left justification motor 6u and the right justification motor 6h rotate CW, the twist tie 2 from which the wing claw 6a has been cut is lifted as shown in FIG. 73B.

  At time t12 shown in FIG. 117C, the control unit 88a inputs a left-justified motor end detection signal S88h of “H” level from the left-justified motor origin sensor 88t, and stops driving the left-justified motor 6u. Further, the control unit 88a inputs the right-alignment motor origin detection signal S88i of “H” level from the right-alignment motor origin sensor 88i at time t12 shown in FIG. 117F, and stops driving the right-alignment motor 6h.

  The control unit 88a drives the left justification motor 6u in the CCW direction at time t13 shown in FIG. 117C. Further, the control unit 88a drives the right-justification motor 6h in the CCW direction at time t14 shown in FIG. 117F. When the left justification motor 6u and the right justification motor 6h rotate CCW, as shown in FIG. 73C, the twist tie 2 with the wing claw 6a cut is formed into a U shape.

  At time t14 shown in FIG. 117D, the control unit 88a inputs a left-justified motor end detection signal S88h of “H” level from the left-justified motor end sensor 88h, and stops driving the left-justified motor 6u. Further, the control unit 88a inputs a right-aligned motor end detection signal S88j of “H” level from the right-aligned motor end sensor 88j at time t15 shown in FIG. 117G, and stops driving the right-aligned motor 6h. Thereafter, the control unit 88a outputs a twist tie forming completion signal SS88 'to the control unit 87a of the transport system.

  When the twist tie forming completion signal SS88 'is input, the control unit 87a drives the twisting motor 87v of the twist tie 2 shown in FIG. 116P by, for example, 500 steps in the CCW direction by the motor control signal S87b. When the torsion motor 87v is rotated, the S-shaped member 8a shown in FIG. 74 is rotated and the twist tie 2 is fastened.

  At time t19 shown in FIG. 116Q, the control unit 88a inputs the “H” level torsion rotation detection signal S87p from the twist tie torsion origin sensor 87p and stops driving the torsion motor 87v.

  The path control unit 88a drives the left justification motor 6u in the CW direction at time t18 shown in FIG. 117D. Further, the control unit 88a drives the right-justification motor 6h in the CW direction at time t18 shown in FIG. 117G. When the left justification motor 6u and the right justification motor 6h rotate CW, the wing claw 6a returns to the initial position as shown in FIG. 75A.

  At time t19 shown in FIG. 117C, the control unit 88a inputs a left-justified motor origin detection signal S88g of “H” level from the left-justified motor origin sensor 88t, and stops driving the left-justified motor 6u. Further, the control unit 88a inputs the “H” level right-alignment motor origin detection signal S88i from the right-alignment motor origin sensor 88i at time t19 shown in FIG. 117F and stops driving the right-alignment motor 6h.

  The control unit 87a drives the vertical motor 20a in the CW direction at time t20 shown in FIG. 116L. When the vertical motor 20a rotates in the CW direction, as shown in FIG. 81A, the ascending / descending mechanism 20 operates to lower the tag transport mechanism 4 and the twist tie set mechanism 6.

  Further, the control unit 87a drives the horizontal motor 4a in the CW direction at time t20 shown in FIG. 116O. When the horizontal motor 4a rotates in the CW direction, the tag transport mechanism 4 moves the tag hook 43 backward as shown in FIG. 53A.

  Also, the control unit 87a drives the twist tie feed motor 5a in the CCW direction by, for example, 270 steps by the motor control signal S87d at time t20 shown in FIG. 116I. When the twist tie feed motor 5a rotates CCW, the twist tie feed mechanism 5 shown in FIG. 102 operates to pull back the twist tie 2. In addition, the control unit 87a outputs a process execution signal SS87a indicating that it returns to the initial state to the control unit 50 of the bag mouth fan drive unit 40.

  The control unit 87a confirms that the switch-on signal SS9 is turned off at time t28 shown in FIG. 116B. The control unit 87a outputs a processing execution signal SS87b indicating that the shutter is closed to the path-system control unit 88a at time t29 shown in FIG. 116E. Also, the control unit 87a drives the tag feed motor 39k in the CCW direction by the motor control signal S87c at time t29 shown in FIG. 116G. When the tag feed motor 39k rotates, the tag feed mechanism 3 shown in FIG. 58 operates to feed only one tag 10 from the cartridge 17.

  At time t30 shown in FIG. 116H, the control unit 87a receives the tag detection signal S87q from the tag sensor 87q and stops driving the tag feed motor 39k. As a result, as shown in FIG. 59A, the extended tag 10 stops in a state where it is locked to the tag hook 43.

  The control unit 87a drives the twist tie feed motor 5a by, for example, 300 steps in the CW direction by the motor control signal S87d at time t30 shown in FIG. 116I. When the twist tie feed motor 5 a rotates, the twist tie feed mechanism 5 shown in FIG. 102 operates to pull out the twist tie 2 from the bobbin 58.

  Further, the control unit 87a drives the horizontal motor 4a in the CCW direction by the motor control signal S87e at time t30 shown in FIG. 116M. When the horizontal motor 4a rotates in the CCW direction, the tag transport mechanism 4 advances the tag hook 43 as shown in FIG. 56A. At this time, the concave portion 10 e of the tag 10 is hooked on the claw portion 43 a of the tag hook 43.

  The path-system control unit 88a drives the shutter motor 88e in the CW direction by the motor control signal S88b at time t30 shown in FIG. 117H. When the shutter motor 88e is rotated, the shutter plate of the shutter mechanism 89 (not shown) provided between the mounting table 81a and the mounting table 81b shown in FIG. 1 is closed.

  FIG. 118 is a flowchart showing an operation example of the bag mouth fan folding tag binding device 100. In step ST1 shown in FIG. 118, the power of the bag mouth fan folding tag binding device 100 is turned on, and the process proceeds to step ST2.

  In step ST2, the twist tie 2 is set in the tag attachment drive unit 101. For example, the twist tie 2 is pulled out from the bobbin 58, inserted between the feed knurl 5m and the feed roller 5k shown in FIG. 102A, and sandwiched by the toggle clamp mechanism 5c. Then, the twist tie set switch of the operation unit 87z shown in FIG. 114 is turned on to send the twist tie 2 to the binding position, and the process proceeds to step ST3.

  In step ST3, the tag 10 is set in the apparatus. For example, the cartridge 17 loaded with the tag 10 is attached to the cartridge setting unit 26, and the tag set switch of the operation unit 87z is turned on. Thereby, the tag 10 of the cartridge 17 is sent out by the tag feeding mechanism 3 and the tag transport mechanism 4. Subsequently, the process proceeds to step ST4.

  In step ST4, when the switch 90 provided at a predetermined position of the table 81 shown in FIG. 1 is turned on with the table 81 being lightly dropped, the process proceeds to step ST5 and step ST6.

  In step ST5, the control unit 50 of the bag mouth fan forming drive unit 40 inputs the switch-on signal SS9 and focuses the package. For example, a vertical motor 58a (not shown) is driven to close the upper frames 11a and 11b having the mountain folding mechanism 60. Further, when the fan left motor 59a shown in FIG. 3 rotates, the lower arm 72a of FIG. 38 is contracted and the upper arm 62a is contracted. Further, by rotating the fan right motor 59b, the lower arm 72b of FIG. 38 is contracted and the upper arm 62b is contracted, and the process proceeds to step ST9.

  In step ST6, the tag attachment drive unit 101 secures a route for sending the twist tie 2 to the tag 10. For example, as shown in FIG. 71B, the wing claws 6a of the right wing portion 6R and the left wing portion 6L are closed and the tag 10 is pressed, and the process proceeds to steps ST7 and ST8.

  In step ST7, the twist tie 2 is passed through the tag 10. For example, the twist tie feed mechanism 5 drives the twist tie feed motor 5 a to pull out the twist tie 2 from the bobbin 58 and send it out.

  In step ST8, the shutter plate of the shutter mechanism 89 for taking out the tag 10 is opened. For example, the shutter motor 88e shown in FIG. 115 is driven to open the shutter plate of the shutter mechanism 89 provided between the mounting table 81a and the mounting table 81b shown in FIG. After completing steps ST7 and ST8, the process proceeds to step ST9.

  In step ST9, the twist tie 2 is cut. For example, the ascending / descending mechanism 20 shown in FIG. 79 drives the vertical motor 20a to raise the tag transport mechanism 4 and the twist tie set mechanism 6. At this time, the twist tie cut mechanism 7 shown in FIG. 78B cuts the twist tie 2 to a predetermined length. Also, the twist tie feed mechanism 5 shown in FIG. 47 drives the twist tie feed motor 5a to pull back the twist tie 2 once. Subsequently, the process proceeds to step ST10.

  In step ST10, the twist tie 2 is flipped up. For example, the twist tie set mechanism 6 shown in FIGS. 73A to C drives the left justification motor 6u and the right justification motor 6h to form the twist tie 2 in a U shape, and proceeds to step ST11.

  In step ST11, the twist tie 2 is twisted. For example, the twist tie twisting mechanism 8 shown in FIG. 74 drives the twisting motor 87v to rotate the S-shaped member 8a to fasten the twist tie 2 and proceeds to step ST12.

  In step ST12, the operator takes out the package 1 equipped with the tag 10 from the apparatus. At this time, the raising / lowering mechanism 20 shown in FIG. 79 drives the vertical motor 20a to lower the tag transport mechanism 4 and the twist tie set mechanism 6. Further, the tag transport mechanism 4 shown in FIG. 53 drives the horizontal motor 4a to retract the tag hook 43. The twist tie feed mechanism 5 shown in FIG. 47 drives the twist tie feed motor 5a to further pull back the twist tie 2 once.

  Further, the vertical motor 58a is driven to open the upper frames 11a and 11b having the mountain folding mechanism 60. Further, when the fan left motor 59a shown in FIG. 3 rotates, the lower arm 72a of FIG. 38 is expanded and the upper arm 62a is expanded. As the fan right motor 59b rotates, the lower arm 72b of FIG. 38 is expanded and the upper arm 62b is expanded. The twist tie set mechanism 6 shown in FIG. 75A drives the left justification motor 6u and the right justification motor 6h to move the wing claw 6a to the initial position. Subsequently, the process proceeds to steps ST13 and ST14.

  In step ST13, the tag 10 is prepared. For example, the tag feed mechanism 3 shown in FIG. 58 drives the tag feed motor 39k to feed only one tag 10. The tag carrying mechanism 4 shown in FIG. 63A drives the horizontal motor 4 a and carries the tag 10 by the tag hook 43. Further, the twist tie feed motor 5a is driven to feed the twist tie 2 to the standby position.

  In step ST14, the shutter plate of the shutter mechanism 89 for taking out the tag 10 is closed. For example, the shutter motor 88e shown in FIG. 115 is driven to close the shutter plate of the shutter mechanism 89 provided between the mounting table 81a and the mounting table 81b shown in FIG. After completion of steps ST13 and ST14, the process proceeds to step ST15 to determine whether or not the power is turned off. If the power is not turned off, the process returns to step ST4. When the power is turned off, the bag mouth fan folding tag binding process is terminated.

  The present invention relates to a bag mouth in which a bag mouth of a packaging body containing food, other products, etc. is folded into a bellows shape to form a fan shape, and a tag is attached in the vicinity of the main part of the fan shape.
