Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a label supply for supplying a label having a display unit such as a size display and a laundry display to a cloth such as clothes or towels for sewing. The present invention relates to an apparatus and a label supply method. More specifically, a label supply apparatus and a label supply method for supplying the label in a state where the sewing end of the label overlaps the lip of the cloth and the display unit is located above the cloth inside the lip. About.

[Related Art] As a conventional label supply device, there is one having the following configuration. That is, the label supply device has a gripper that can reciprocate between the label storage location and the label sewing location. The gripper comes to the label location and pinches a part of the label. The gripper holding the label moves forward to the label sewing location,
The forward end of the label is overlapped with a predetermined sewn portion of the cloth. The overlapped ends are sewn with a sewing machine. Such an apparatus is disclosed, for example, in JP-A-63-28.
There is one disclosed in Japanese Patent Publication No. 1681.

[Problems to be Solved by the Invention] When the above cloth is wide, the cloth is generally spread on a table placed in front of the sewing machine in order to smoothly feed the cloth during sewing. For such a cloth edge,
In the case where the sewing end portion of the label is sewn in a state where the label display portion is located above the cloth inside the lip, the conventional label supply device is located above the table. However, the label supply device located in such a place is extremely obstructive to the operation of handling the cloth on the table, for example, the operation of spreading the cloth on the table.

The present invention has been made in order to solve the problems (technical problems) of the above-described conventional technology, and has the following objects.

An object of the present invention is to sew a label on a cloth so that a sewing end of the label overlaps a sewn edge of the cloth and a display portion of the label is on a cloth inside the rim. It is an object to provide a device capable of supplying a label in a position.

Another object of the present invention is to provide an apparatus capable of supplying a label from the outside of a sewn edge when supplying the label in the above state. A device capable of such a supply can be provided near the lip and at an external location off the top of the table for receiving the cloth. Then, the space above the table becomes empty, and the workability of handling the cloth on the table is improved.

Another object of the present invention is to provide an apparatus and a supply method capable of supplying a label with a constant length protruding from a gripping tool even if the length of the supplied label is changed. It is to provide. If the length of the above part is constant, the gripper only needs to move to the home position to provide a label of any length, and the sewing end of the label is correctly positioned on the edge of the cloth. Let me do. This enables simplification of a mechanism for moving the gripping tool toward the sewing location, and simplifies control of the movement.

Still another object of the present invention is to provide an apparatus and a supply method capable of supplying a single label or a two-fold label. Moreover, even in the case of the supply, an object of the present invention is to provide an apparatus and a supply method capable of supplying a label with a constant length of a portion protruding from a gripping tool.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the means described in the claims, and the operation is as follows.

[Operation] A part of the label at the label storage location is inserted into the gripping tool by the pushing piece. The gripper sandwiches the inserted part. The gripper moves toward the sewing location. In this movement, the end of the label protruding from the gripper strikes a lip on the table or cloth receiving the cloth, the end of which bends in the direction opposite to the direction of movement of the gripper. And its end overlaps the edge of the cloth to be sewn. In this state, the portion sandwiched between the grippers is located above the cloth inside the lip.

[Embodiment] Drawings showing an embodiment of the present application will be described below.

FIGS. 1 and 3 show a first embodiment of a label supply apparatus according to the present invention.
Are a base frame 2, a cutting device 3 provided on the base frame 2, a label table 4 whose upper surface is a label storage place for storing labels, and a label provided below the label table 4. It has a pushing device 5, a gripper 6 provided above the label table 4, and a restraining device 7 for restraining a part of the label on the label table 4.

The cutting device 3 has a function of cutting a long strip 10 to form a label and a function of preparing the formed label on a label table 4. Hereinafter, the cutting device 3 will be described. The housing 11 of the cutting device 3 is provided so as to freely move in the direction of the arrow shown in FIG. 1 along a rail 12 attached to the base frame 2. The housing 11 has an inlet 13 for the band 10 on one side and an outlet 14 on the opposite side. Inside a band between the inlet 13 and the outlet 14
It has a receiving plate 15 that receives the 10 and guides its movement. Inside the housing 11, there is a pair of feed rollers 16 for feeding the strip 10. These feed rollers 16 are rotated in the direction of the arrow by a drive motor (not shown) while sandwiching the belt-shaped body 10. By this rotation, the strip 10 is drawn in from the inlet 13 and sent out from the outlet 14. A cutter 17 for cutting the strip 10 is provided near the outlet 14 in the housing 11. In addition, near the entrance 13, a mark sensor 18 for detecting a mark attached to the strip 10 to indicate a cut point is provided.
Are provided along the path of the band 10. The strip 10 is formed in such a state that a number of label elements which become labels one by one by being separated from each other are connected in series. The mark is attached to each boundary between adjacent label elements. Therefore, in the band 10 having a long label element (a band for forming a long label), the interval between the marks is long, and each label element has a short band 10 (a band for forming a short label). In the band-like body), the interval between the marks is short.
One example of the strip 10 is a textile tape. Another example is a smooth tape made of synthetic resin. The drive motor of the feed roller 16 and the sensor 18 are connected to a controller (not shown). The control device rotates the drive motor. And
When the sensor 18 detects a mark, it receives the signal. Then, when the feed roller 16 feeds the belt-shaped body 10 by a dimension that the detected mark just reaches the position of the cutter 17, the drive motor is stopped.

A moving device 21 is provided for moving the housing 11 along the rail 12. The moving device 21 includes a pair of bearings 22, 22 fixed to the base frame 2, a feed rod 23 rotatably supported by the bearings 22, 22, and a handle 24 for rotating the feed rod 23. And a mover fixed to the housing 11
With 25. The feed rod 23 is a screw rod, and is screwed with a screw hole formed in the movable member 25. When the feed rod 23 is rotated by the handle 24, the mover 25 moves along the feed rod 23, and as a result, the housing 11 moves along the rail 12.

The label table 4 is mounted on the housing 11 of the cutting device 3 in this embodiment,
It moves with the housing 11. A plurality of slits 27 are formed in the label table 4 to allow a pushing piece, which will be described later, to pass through the label storage location. As shown in FIG. 1, each slit 27 is formed to be long in the moving direction of the table 4 by the moving device 21.

The pushing device 5 includes a pushing piece 31 and an advance / retreat device 32 for moving the pushing piece 31 forward and backward. The pushing piece 31 is formed in a comb shape having a plurality of pushing piece elements 33. Each pushing piece element 33 has a width capable of passing through the slit 27 of the table 4. Each push piece element
As shown in FIG. 4A, the tip of 33 has a chevron shape and the tip has a small round shape. However, it may have a shape as shown in FIG. 4B. The reciprocating device 32 is an air cylinder 34 mounted on the base frame 2 in this embodiment. At the tip of the piston rod 34a in the air cylinder 34,
One is installed.

A ruler device 36 is provided to limit the advance amount of the pushing piece 31 to a predetermined size. The ruler device 36 includes a contact member 37 integrally formed on both sides of the pushing piece 31 and a stop member 38 attached to the label table 4. The stop member 38 has a stop surface 39 on a side facing the contact member 37. The stop surface 39 has an inclination of 45 degrees with respect to the moving direction of the label table 4.

Next, the gripper 6 will be described. Main body of gripper 6
41 is a known transport device 42 (only a part is shown)
Mounted on The gripper 6 is reciprocated between the gripping location A and the sewing location B shown in FIG. The main body 41 has a movable piece 41 that moves toward and away from each other.
a, 41a are provided. A gripping piece 43 formed of an elastic member is attached to each movable piece 41a. The tip of each gripping piece 43 is a gripping portion 44. A non-slip member 44a (for example, a rubber piece) having a large friction with the label is attached to the grip portion 44. A label receiving portion 45 is provided between the two grip portions 44. The gripping place A is set at a fixed position where the label receiving portion 45 faces the pushing piece 31 so that the label pushed out by the pushing piece 31 can be received by the label receiving portion 45. A label guide 46 is provided near the label table 4 in association with the gripper 6. Although not shown, the label guide 46 is fixed to the base frame 2. The label guide 46 and the label table 4 are spaced apart from each other so that the label can pass. The label guide 46 has a gap 47 at a position facing the pushing piece 31 to allow the pushing piece 31 to pass therethrough.
When the gripper 6 is located at the gripping location A, the gripping piece 43
If the leading end is located sufficiently close to the label table 4, the label guide 46 is omitted.

The restraining device 7 includes an air cylinder 48 attached to the housing 11 of the cutting device 3 and a pressing piece 49 attached to the tip of a piston rod 48a of the air cylinder 48.

Next, FIG. 2 shows a label sewing apparatus 51 as an example of an apparatus for receiving a label. The apparatus 51 has a sewing machine table 52, a cloth receiving table 53 formed continuously with the sewing machine table 52, a sewing machine head 54 provided above the sewing machine table 52, and a cloth on which a label is to be sewn. Sewing machine table from cloth receiving table 53 with label
A transport device 55 for transporting toward 52 is provided. Transfer device 55
Has a guide rail 56. A moving frame 57 is movably attached to the guide rail 56 along the rail. An air cylinder 58 is mounted on the moving frame 57.
The presser body 59 is attached to the lower end of the piston rod.
A non-slip piece (for example, a thin band-shaped rubber piece) showing a large frictional force with the cloth is attached to the lower surface of the cloth presser 59.
A feed mechanism 60 is connected to the moving frame 57. The feed mechanism 60 is composed of a pulley 61 and a belt 62 hung on the pulley 61 (for example, a cogged belt is used). The connecting piece of the moving frame 57 is attached to the belt 62.

Next, supply of a label to the label sewing device 51 by the label supply device 1 and sewing of the supplied label by the label sewing device 51 will be described. In the sewing device 51, the cloth 64 to be sewn with the label is spread on the table 53. An edge 64a of the cloth 64 is a portion to which the sewing end of the label is to be sewn. In this state, the label is supplied by the label supply device 1 as follows.

First, supply of a relatively long folded label by the label supply device 1 will be described with reference to FIGS. 3, 5, 6A, 6B, and 7A, 7B. In order to form the above label,
A strip 10 having a long interval between cutting marks is used. Further, the cutting device 3 and the label table 4 are moved by the moving device 21 so that the distance L1 between the cutter 17 and the pushing piece 31 is changed to the band 10
Spacing between marks in (length of one label element)
So that it is 1/2 of In this state, the belt 10 is first fed by the feed roller 16. By this feeding, the label element 10a corresponding to one label is sent out in front of the cutter 17, and gets on the label table 4 as shown in FIGS. 6A and 7A. Next, the piston rod 48a of the restraint device 7
Is extended, and the label element is pressed against the table 4 by the pressing piece 49. In this state, the cutter 17 operates. As a result, the label elements on the table 4 are cut off to form one label 65. The front end 65 of the label 65
a and the rear end 65b are sewing ends, and a portion 65c between them is a display unit. The band 10 is formed in advance in such a state. Next, the piston rod 34a of the cylinder 34 is extended. Then, the pushing piece 31 pushes the intermediate portion of the label 65 on the label table 4 as shown in FIGS. 6B and 7B, and pushes it through the gap 47 of the label guide 46 as shown in FIG. 6B. Press into 45.
The pushing piece 31 is advanced to a position where the contact member 37 contacts the stop surface 39. Next, the pressed label 65 is elastically gripped by the gripping pieces 43 of the gripping tool 6. Next, the pushing piece 31 is retracted by the contraction of the cylinder 34. Next, the gripper 6 is laterally moved to the sewing place B by the moving device 42. As shown in FIG. 3, the locus of the movement is a part of the portion 65d of the label 65 protruding from the gripper 6, for example, the locus of the lower half of the portion 65d near the sewing place B. It is set at a position where the object, for example, the table 53 blocks. Accordingly, when the gripper 6 moves along the movement locus and approaches the sewing location B, the lower half of the protruding portion 65d hits the table 53. If the gripper 6 still moves,
The protruding portion 65d bends in a direction opposite to the moving direction of the gripper 6. When the gripper 6 reaches the sewing place B,
Sewing ends 65a, 65b that are the tip of the protruding portion 65d
Overlaps the edge 64a of the cloth 64. In this state, as a matter of course, the display portion 65c of the label 65 is located above the cloth inside the edge 64a. Note that the target object near the sewing location may be the edge 64a of the cloth 64. In this case, the movement locus of the gripper 6 is determined by the end portions 65a and 65
b is determined to hit the edge of the edge 64a of the cloth 64 and bend in the same opposite direction as above.

When the label 65 is supplied as described above, the sewing device
51 operates as follows. By the operation of the feed mechanism 60 and the cylinder 58, the presser foot 59 moves as indicated by an arrow 66 in FIG.
The cloth 54 and the supplied label 65 are pressed against the table 53. In this state, the gripper 6 releases the label 65 and returns to the gripping location A. Next, the presser body 59 is moved in the direction of arrow 67 by the feed mechanism 60. By this movement, the cloth 64 to which the label 65 is attached slides on the upper surface of the table 53 and moves together with the cloth presser 59, and reaches the sewing machine table 52. Furthermore, it slides on the table 52 and moves. During the moving process, the sewing head 54 sewes the sewing end of the label 65 to the edge 64 a of the cloth 64. When the sewing is completed, the work clamp body 59 is raised by the cylinder 58 and
64 is released. The released cloth 64 is carried to the next process.

The supply of the label and the sewing of the label as described above are repeatedly performed one after another, and the label is attached to each of a large number of cloths.

Next, an operation when the length of the label is changed to, for example, a shorter one will be described. The strip 10 used in this case is a strip having a short distance between the cutting marks. In the label supply device 1, the distance between the cutter 17 and the pushing piece 31 is set to L1 'in FIG.
As shown by. That is, the distance between the marks in the new belt-like body is set to 1/2. In this state, the same operation as described above is performed. The state is as shown in FIGS. 8A and 8B. These figures show states corresponding to FIGS. 6A and 6B. In the case of the above operation, the advance of the pushing piece 31 is limited by the abutment member 37 contacting the stop surface 39 while the advance amount is still small. For this reason, the penetration depth of the pushing piece 31 into the label receiving portion 45 is smaller than the depth L2 in FIG. 6B by the depth L in FIG. 8B.
2 'is limited to small. Fig. 8B compared to Fig. 6B
In the case shown in the figure, the decrease in the advance amount of the pushing piece 31 depends on the stop surface.
Since 39 is formed at an inclination of 45 degrees, it is equal to the decrease (L1-L1 ') in the distance between the cutter 18 and the pushing piece 31. As a result, the length L3 of the portion 65d of the label 65 protruding from the gripper 6 is the same as that in the case of FIG. 6B. Therefore, when the gripper 6 is moved to the sewing place B, the sewing end of the label 65 overlaps the edge of the cloth as in the case of the long label. The length L3 is referred to as a required projection size in the present specification.

Next, the label supply device 1 can form a single label and supply it to the sewing device 51. The band used in this case is formed such that the rear end (the end adjacent to the cutter 17) of the label cut at the mark becomes the sewing end and the other part becomes the display.

The formation and supply of a single label is performed by moving the cutting device 3 and the label table 4 by the moving device 21 in FIGS. 10A, 10B and 1.
1 Move to the position shown in Fig. At this position, the distance from the lower end of the gripper 6 to the cutter 17 through the gap 47 in the label guide 46 is equal to the length L3 (= L1−L
This is the position that is equal to 2). When the table 4 is in the above position, the stop member 38 is no longer retracted from the position above the stop member 37. Therefore, the pushing piece 31 can move forward to the uppermost position.

The formation and supply of a single label is performed by operating the respective devices in the order shown in FIG. The difference from the two-fold label case (Fig. 5) is that the cutter
This is the point that the restraining device 7 restrains the label in the entire process of cutting by the 17 and advancement of the pushing piece 31.

First, as shown in FIG. 10A, a label element 10b corresponding to one label is sent out onto the table 4 as in the case of the two-fold label. Next, the label is cut by the cutter 17 into a label 70. At this time, the rear end of the label 70 on the label table 4, that is, the sewing end 70a is pressed as shown in FIG. 10B.
Retained by 49. In this restrained state, the tenth
The pushing piece 31 advances to the uppermost position as shown in FIG. Then, the other end of the label 70 enters the receiving portion 45 of the gripper 6 as shown in FIG. 10B. Next, the gripper 6 sandwiches the label 70. After that, the restraint is released, and the pushing piece 31
Is pulled out. Thus, the gripper 6 is in a state where the label 70 is gripped. In this case, since the table 4 is located at the position as described above, the length of the portion of the label 70 protruding from the gripper 6 is the same as that of the two-fold label. Such a label 70 is supplied to the sewing device 51 as in the case of the two-fold label.

The operation in the case of supplying a single short label by the label supply device 1 is exactly the same as the above-described case.
In this case, as shown in FIG. 11, the length of the label 70 that enters the receiving portion 45 of the gripper 6 is shorter than in the above case. The length of the portion protruding from the gripper 6 is the same as that of the long label.

In the label supply device 1, as described above, the pushing pieces 31 are formed in a comb shape. For this reason, as shown in FIG. 12, a wide label 65 'can be placed on the label table 4 and pushed by the pushing piece 31.

Next, FIG. 13 shows a second embodiment of the label supply device. The label supply device 1e shown in FIG.
The advancing / retreating device 32e and the restraint device 7e in FIG. First, the retracting device 32e will be described. Base frame 2e
Has a support frame 75 attached thereto. The support frame 75 is a pair of bearings 76,7
The feed screw rod 77 is rotatably supported by these bearings. A motor 78 is mounted on the support frame 75, and an output shaft 79 of the motor 78 is connected to the screw rod 77 by a coupling 80. A mover 82 is provided to be vertically movable along a guide portion 81 of the support frame 75. This mover
A pushing piece 31e is attached to 82. The moving element 82 is screwed to the screw rod 77. The output shaft 79 is used as the motor 78.
A motor that can control the number of rotations or the rotation angle of is used. An example of such a motor is a stepping motor.

In such an advance / retreat device 32e, the forward dimension of the pushing piece 31e can be extremely accurately controlled by controlling the number of rotations or the rotation angle of the motor 78. That is, the motor 78 functions as a ruler device for limiting the advance amount of the pushing piece 31e.

Next, the restraining device 7e has a structure in which the label is restrained by vacuum suction. That is, a suction pipe 83 is attached to the label table 4e, and one end of the suction pipe 83 is opened as an adsorption section 84 on the upper surface of the table 4e near the outlet 14e of the cutting device 3e. A suction tube 85 is connected to the other end of the pipe 83, and the other end of the tube is connected to a suction device 86.

In this label supply device, a two-fold or single label can be supplied by the same operation as the label supply device. In addition, the two-fold label can be supplied as follows. That is, as shown in FIGS. 15A to 15C, the label table 4e is positioned in the same manner as in the case of supplying a single label in the embodiment. Then, as shown in FIG. 14, each device operates in the same order as in the case of supplying the single label. In this operation, the pushing piece 31e is
The vehicle advances from the state shown in the figure as shown in FIGS. 15B and 15C. Then, as shown in FIG. 15C, the advance ends when the lengths of the portions located on the left and right sides of the pushing piece 31e on the label 65e become the same. Such advance is performed by controlling the rotation speed or rotation angle of the motor 78 according to the length of the label 65e by a control device (not shown).

In addition, parts that are considered to have the same or equivalent configuration as those of the previous embodiment in terms of function are denoted by the same reference numerals as in the previous embodiment, and the repeated description is omitted by adding the letter e of the alphabet.

(Also in the subsequent figures, alphabetical letters f, g, etc. are added in order in the same way, and duplicate explanations are omitted.) Next, FIGS. 16 and 17 show different examples of label guides. Is shown. This label guide 46f can be used, for example, instead of the label guide of the label supply device in FIG. The label guide 46f includes a plurality of rollers 92 rotatably mounted on shaft rods 91, 91, respectively. Each roller 92 is prevented from coming off the shaft 91 by stoppers 93 and 94 fixed to the shaft 91. Each of the shafts 91 is a cylinder attached to the base frame 2f.
It is attached to the piston rod 95a of 95 by an attachment 96, and moves up and down as the piston rod 95a advances and retreats.

The supply of the label by the label supply device using the label guide 46f is performed by each device operating in the order shown in FIG. This operation is the same as the operation of the label supply device of FIG. 3 except for the vertical movement of the label guide 46f (see FIG. 5). The label guide 46f is at the raised position when the belt is fed. Therefore, the strip can pass under the label guide 46f without any trouble. When the feeding of the band is completed and the restraining device restrains the band, the label guide 46f is lowered and rides on the band. In this state, the strip is cut into a label, and then the pushing piece is advanced. Therefore, the label 65f is kept pressed on the label table. As a result, an accident that the label escapes from the label table is prevented. In this case, since the roller 92 is rotatable, the movement of the label 65f due to the advance of the pushing piece does not interfere.

The label guide 46f includes a plurality of rollers 92. Therefore, when the width of the label is small, only the roller 92 in contact with the label can rotate independently. Therefore, the movement of the narrow label is performed without any trouble.

19 and 20 show a third embodiment of the label supply device. This label supply device 1g has a moving mechanism 21g having a structure different from that of the label supply device of FIG. The feed rod 101 is rotatably supported by a pair of bearings 22g, 22g. The feed rod 101 is constituted by a screw rod. A mover 102 is screwed into the feed rod 101.
One end of a connecting rod 103 is connected to the moving element 102. Connecting rod
The other end of 103 enters the housing through a window 104 formed in the housing 11g and is connected to the mark sensor 18g. A right-handed screw and a left-handed screw having the same pitch are used as the feed rod 23g and the feed rod 101, respectively. Each is provided with a pair of gears 105, 106 for interlocking the two. The gear ratio between the gear 105 and the gear 106 is 3: 1.

Further, in the above label supply device, the interlocking relationship between the mark sensor 18g and the feed roller 16g is different from the label supply device of FIG. The relationship will be described with reference to FIG. In this example, when the mark sensor 18g detects the mark 107 during the feeding of the belt 10g by the feed roller 16g, the feeding of the belt 10g is stopped. Therefore, the distance L4 between the cutter 17g and the sensor 18g
Is matched with the distance between the marks 107, the mark 107 can be positioned exactly at the position of the cutter 17g.

In the above label supply device, the feed rods 23g and 101 and the gear 10
Since the members 5 and 106 are configured as described above, when the moving device 21g is operated, the housing 11g and the sensor 18g move in the same direction. And the ratio of those movement dimensions becomes 1: 3. In use, the distance between the mark sensor 18g and the cutter 17g is adjusted to the distance between the marks 107 by operating the moving device 21g according to the band used. Then, push-in piece 31g and cutter 17
The distance from g automatically becomes 1/2 of the distance between the marks 107 (the length of the label). That is, the center of the separated label comes to face the pushing piece 31g.

Next, FIGS. 22 and 23 show different structural examples of the tip of the pushing piece element. In the example of FIG. 22, a point 108 is formed at the tip of the pushing piece element 33h. The example in Fig. 23 is a push piece element 3.
A plurality of needles 109 are provided at the tip of 3i. When these tips press the middle of the label, the tip 108 or the needle 109 gets caught (stabs) in the label. As a result, lateral displacement of the label is prevented.

Next, FIG. 24 shows a folded hem forming apparatus as another example of the apparatus for receiving the supply of labels. This apparatus is known (for example, Japanese Patent Publication No. 59-46194),
11, a folding tool 112, a ruler 113 and the like. The label 65j is carried by the gripper 6j, and the sewing end 65aj is positioned as shown against the once folded lip 114a of the cloth (eg, a towel) 114. Next, the lip 114a is folded as indicated by a two-dot chain line by the movement of the folding tool 112 indicated by arrows 116 and 117 with reference to the ruler 113. Next, after removing the ruler 113, the portion indicated by reference numeral 118 is sewn.

Next, as a form of movement of the gripper, there is an oblique movement as shown in FIG. 25 in addition to the lateral movement. Alternatively, there is an arc movement around the point 120 as shown in FIG.

[Effects of the Invention] As described above, according to the present invention, there is an effect that the above objects can be achieved and labels can be supplied appropriately.
