  2A and 2B are explanatory diagrams illustrating a configuration example of the tag 1A used in the binding machine 100. FIG. FIG. 2A is a front view of the tag 1A.

  A tag 1A shown in FIG. 2A is configured by integrally forming an information presentation unit 10A, a mounting unit 11A, and a connecting unit 12A with a thin plate material such as paper or plastic. The connecting portion 12A is a region surrounded by two broken lines shown in FIG. 2A. This region is defined by the boundary line between the attachment part 11A and the connection part 12A and the boundary line between the connection part 12A and the information presentation 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 11A is provided with two locking holes 11m and 11m, and is locked to the binding tool 13 'after cutting. When the longitudinal direction of the tag 1A shown in FIG. 2 is the vertical direction, the locking holes 11m and 11m are configured by forming two through holes at predetermined intervals in the lateral direction of the tag 1A. The connecting portion 12A has recesses 12m and 12m formed by cutting out a part of both sides of the information presentation portion 10A into a predetermined shape, and the mounting portion 11A and the information presentation portion 10A are narrower than the information presentation portion 10A. Link. The recesses 12m and 12m are configured by forming a rectangular groove in part of both sides of the information presentation unit 10A. FIG. 2B shows a perspective view of the tag 1A.

  FIG. 3 is a perspective view illustrating a configuration example of the binding tool 13. The binding tool 13 shown in FIG. 3 is generally referred to as a twist tie or the like, and is configured by covering a thin wire 13a as a core wire of plastic or metal with a covering material 13b such as resin or paper. The binding tool 13 has a narrow tape shape (band shape) and is passed through the locking holes 11m and 11m of the tag 1A and fastened to the bag 14.

  Next, a function example of the binding machine 100 will be described with reference to FIGS. 1 and 4. 4A to 4D are process diagrams illustrating an example of functions of the binding machine 100.

  4A is a perspective view showing an example of the movement of the tag 1A to the fold fold of the bag 14. FIG. In this example, the tag 1A is transported to the tag holder mechanism 3A by the tag transport mechanism 4A shown in FIG. 1, and the tag 1A is held by the tag holder mechanism 3A and moved toward the binding tool forming mechanism 6A.

  FIG. 4B is a perspective view showing an example of inserting the binding tool 13 into the tag 1A. In this example, the binding tool transport mechanism 5A shown in FIG. 1 pulls out the binding tool 13 wound around the bobbin 52 by about 80 mm, and passes the leading end of the binding tool 13 through the two locking holes 11m and 11m of the tag 1A. To work.

  FIG. 4C is a perspective view showing a configuration example before twisting of the binding tool 13 passed through the tag 1A. In this example, the overall length of the binding tool 13 ′ is set to about 80 mm, for example. The binding tool 13 passed through the tag 1A shown in FIG. 4C is cut at a portion of about 80 mm from the tip, and is shaped so that the rear end and the tip of the binding tool 13 'after cutting are brought together. For example, after the leading end of the binding tool 13 is passed through the one locking hole 11m, the traveling direction of the binding tool 13 is U-turned according to the shape of the tag holder mechanism 3A, and the leading end of the binding tool 13 is locked to the other locking hole. Pass through hole 11m. After the insertion, the binding tool forming mechanism 6 </ b> A shown in FIG. 1 cuts the predetermined position of the binding tool 13. After cutting, the binding tool forming mechanism 6A brings both ends of the binding tool 13 'close to the bag 14 and regulates the shape of the binding tool 13' after cutting into a U-shape. Note that a twisting arm 70 as shown in FIG. 4C having an S-shaped portion 70a at the tip is used for the bundling process of the bundling tool 13 '.

  4D is a perspective view showing an example of fastening by the binding tool forming mechanism 6A shown in FIG. According to the fastening example shown in FIG. 4D, the rear end portion and the front end portion of the binding tool 13 ′ after cutting, which are regulated to be U-shaped, are twisted and fastened by the binding tool fastening mechanism 7 </ b> A. In this example, the S-shaped portion 70a of the torsion arm 70 shown in FIG. 4C holds both ends of the binding tool 13 'restricted to a U shape, and the torsion arm 70 is rotated a predetermined number of times. Thereby, the binding tool 13 ′ is twisted and fastened, and the tag 1 </ b> A is fixed to the fold fold of the bag 14 by the binding tool 13 ′. In this way, the fold fold opening of the bag 14 can be automatically bound and the tag 1A can be fixed.

  FIG. 5 is a perspective view showing a mounting example of the tag 1A. In the bag 14 shown in FIG. 5, a binding tool 13 'is fastened, and a tag 1A is attached by the binding tool 13'. In the tag 1A, the binding tool 13 'is passed through the two locking holes 11m, 11m, and the bag mouth of the bag 14 is bound by the binding tool 13'. It will be along the vertical direction and will not be in the horizontal direction.

  Further, in the tag 1A, since the binding tool 13 'is wound around the bag mouth formed in a rod shape by the bag 14 being squeezed, the mounting portion 11A may be curved following the squeezed shape of the bag 14. However, since the recesses 12m and 12m are formed on both sides of the information presentation unit 10A between the mounting unit 11A and the information presentation unit 10A, and the coupling unit 12A has a narrower width than the information presentation unit 10A. The information presenting unit 10A does not follow the curved shape of the mounting unit 11A, and the information presenting unit 10A is not easily curved. Thereby, the information described in the information presentation unit 10A of the tag 1A can be clearly recognized. And since the information presentation part 10A becomes the vertical direction along the bag 14 without curving, the external appearance of the figure in which the tag 1A is mounted on the bag 14 is improved.

  Subsequently, a configuration example and an operation example of a main part of the binding machine 100 will be described with reference to FIGS. FIG. 6 is a top view showing a configuration example (before binding) of the binding machine 100 and an operation example thereof. A binding machine 100 shown in FIG. 6 is a view of the binding machine 100 shown in FIG. 1 as viewed from above. The binding machine 100 is in a standby state. In the standby state of the binding machine 100, the tag transport mechanism 4A transports one tag 1A to the tag hold mechanism 3A.

  The tag hold mechanism 3A includes a curl guide 30 and is slidably attached to an intermediate chassis 92a constituting the main body. The tag 1A is set in the binding tool forming mechanism 6A and the like by a linear motion of the curl guide 30. Then, the bag 14 is bound by the binding tool 13 'after cutting such as a twist tie by the adjacent binding tool fastening mechanism 7A. The curl guide 30 stands by at the home position HP shown in FIG. In FIG. 6, the home position HP of the curl guide 30 is a state in which the guide flaps 42 a and 42 a of the tag transport mechanism 4 </ b> A are closed, and the curl guide 30 is separated from the guide plate 95 and moved to the leftmost side. In other words, a position where the front end of the curl guide 30 is waiting on the upper extension line of the guide flaps 42a, 42a in the closed state.

  In this example, a tag holder drive mechanism 9A is provided, and in order to move the curl guide 30 in the direction of the arrow Q1, an operation plate 32, a moving motor 93, a ball screw shaft 94, and a torque limiter 33 (see FIG. 20) are provided.

  In this example, a gear 93a is coupled to the output shaft of the moving motor 93, and a gear 94a is engaged with the gear 93a. A gear 94 a is coupled to the ball screw shaft 94. The operating plate 32 is screwed onto the ball screw shaft 94 so as to be slidable. The sliding movement of the operation plate 32 is transmitted to the curl guide 30 via the torque limiter 33. The curl guide 30 receives the operation of the operation plate 32 and moves in a direction in which the curl guide 30 approaches and separates from the opposing binding tool forming mechanism 6A.

  A guide plate mechanism 8A is slidably attached in front of the binding tool forming mechanism 6A. In this guide plate mechanism 8A, sliding movement is detected by a guide plate position sensor (hereinafter referred to as guide plate sensor 107) as shown in FIG. The guide plate sensor 107 constitutes a function of detection means.

  When the user tries to place the bag 14 at the binding port 103 shown in FIG. 6 by the guide plate sensor 107, the guide plate 95 is once pushed by the bag 14 in the arrangement process, and the bag 14 is correctly inserted into the binding port 103. When arranged, the guide plate 95 automatically returns to the illustrated state. By detecting this reciprocating motion by the guide plate sensor 107, it can be determined that the bag 14 has been accurately placed in the binding port 103.

  At this point, the binding machine 100 can start the binding process. In this example, the bag sensor 108 can detect whether the bag 14 has been inserted into the binding port 103 or discharged from the binding port 103. When the guide plate 95 is kept pressed, the binding machine 100 determines that the bag 14 is not accurately placed at the binding port and does not start the binding process. Thereby, defective binding can be avoided.

  Further, the curl guide 30 is provided with a pair of tag hooking claws (hereinafter referred to as tag hooking claws 30b and 30b), and the curl guide 30 holding the tag 1A with the tag hooking claws 30b and 30b guides the curl guide 30. By reaching the plate 95, the guide plate 95 and the curl guide 30 can prevent the tag 1A from falling off.

  The binding tool 13 of the bobbin 52 is pulled out to a predetermined position by the binding tool transport mechanism 5A. In this example, the binder transport mechanism 5A includes a feed roller 50a, driven rollers 50b and 50c, a lever 50d, a tie slope 63, and a binder feed motor 50i.

  The driven roller 50 b is installed in the vicinity of the bobbin 52, and the driven roller 50 c is installed so that the tip of the binding tool 13 faces the entrance of the tie slope 63. The feed roller 50a is installed in the vicinity of the entrance of the tie slope 63, and an output shaft of a feed motor (not shown) is coupled thereto. A lever 50d is abutted against the feed roller 50a.

  In this example, the lever 50d includes a driven roller 50f and a spring 50g, and is rotatably attached to the main body chassis 92. The lever 50d is biased counterclockwise by a spring 50g, and a driven roller 50f is abutted against the feed roller 50a. The binding tool 13 is sandwiched between the driven roller 50f and the feed roller 50a. Accordingly, the binding roller 13 can be pulled out from the bobbin 52 and sent to the tie slope 63 by the clockwise rotation of the feed roller 50a.

  When the bobbin 52 is replaced and the binding tool 13 of the bobbin 52 is first passed through the tie slope 63, the user rotates the lever 50d clockwise to widen the space between the driven roller 50f and the feed roller 50a. Then, the binding tool 13 of the bobbin 52 is passed between them, and the tip of the binding tool 13 is set at the position of the cutter 62.

  The binding tool forming mechanism 6A includes a cutter 62 and left and right approach arms 61a and 61b. The cutter 62 is attached to the main body chassis 92 through cutter links 62a to 62c (see FIG. 8) and a link roller 97. The link roller 97 is pushed together with the sliding movement of the operation plate 32 by the roller arm 101 attached to the lower end portion of the operation plate 32 described above. When the link roller 97 is pushed, the cutter links 62a to 62c coupled to the link roller 97 operate, and the cutter 62 attached to the tip of the cutter link 62c shown in FIG. 8 moves to cut the binding tool 13. To do.

  One end of the left approach arm 61 a is attached to the link roller 97. The approach arm 61a has a V shape. One end of the approach arm 61a is rotatably attached to the link roller 97, and a valley portion of the approach arm 61a is rotatably attached to the main body chassis portion 92 by a pin 105a. Further, a fan-shaped (intermittent) gear 97a is fixed to the valley portion of the approach arm 61a by a pin 105a, and the fan-shaped gear 97a is meshed with one of the connecting gears 96a. The connection gear 96a meshes with the other adjacent connection gear 96b, and the sector gear 97b meshes with the connection gear 96b. A right L-shaped approach arm 61b is attached to the sector gear 97b with a pin 105a.

  With this configuration, when the link roller 97 is pushed, the left approach arm 61a rotates counterclockwise around the pin 105a, and at the same time, the sector gear 97a also rotates counterclockwise around the pin 105a. The connecting gear 96a meshed with the sector gear 97a rotates clockwise. When the connecting gear 96a rotates clockwise, the connecting gear 96b rotates counterclockwise, and the sector gear 97b meshed with the connecting gear 96b rotates clockwise about the shaft support portion 105b, and this sector gear 97b. The right-hand approach arm 61b attached to is also rotated clockwise around the shaft support portion 105b. Accordingly, the left and right approach arms 61a and 61b are closed.

  The left and right approach arms 61a and 61b constitute a part of the tie slope 63 of the tying member 13 in an open state. In this example, the left approach arm 61a forms a tie slope 63 from the position of the cutter 62 to the position of the connect block 31a. The connect block 31 a connects the approach arm 61 a and the curl guide 30. Further, the right approach arm 61 b constitutes a terminal portion of the tie slope 63. The connect block 31b connects between the curl guide 30 and the approach arm 61b.

  The binding tool fastening mechanism 7A includes a torsion arm 70 and a torsion motor (not shown). The torsion arm 70 includes an S-shaped portion 70a (see FIG. 4) at the front end and a gear 70b at the rear end, and the S-shaped portion 70a holds the front end portion and the rear end portion of the binding tool 13 '. The output shaft of the torsion motor is engaged with the gear 70b, and the torsion arm 70 is rotated by the rotation of the unillustrated torsion motor 70c.

The binding machine 100 shown in FIG. 7 is in a binding state in which the bag 14 is bound by a binding tool 13 ′ formed by passing the binding tool 13 through the tag 1 </ b> A and cutting the binding tool 13. In order to shift from the standby state shown in FIG. 6 to this bundling state, the bundling machine 100 first sets the guide plate to the bundling port 103 shown in FIG. It is detected that the mechanism 8A is pressed once and the bag 14 is placed by the bag sensor 108 (see FIG. 35).

  According to the binding machine 100, after detecting the arrangement of the bag 14, the moving motor 93 is rotated forward, and the ball screw shaft 94 is rotated forward via the gears 93a, 94a. The operation plate 32 screwed to the ball screw shaft 94 is slidably moved in the direction of the arrow Q2. The operation of the operation plate 32 is transmitted to the curl guide 30 via the torque limiter 33 (see FIG. 20), and the curl guide 30 receives the operation of the operation plate 32 to the opposite binding tool forming mechanism 6A. In the approaching direction, it moves from the home position HP to the position P1, and pushes in the guide plate mechanism 8A to contact the left and right connect blocks 31a and 31b.

  At this time, the guide plate mechanism 8A prevents the tag 1A from falling off by the tag hooking claws 30b, 30b of the curl guide 30 holding the tag 1A reaching the guide plate mechanism 8A. Further, the curl guide 30 constitutes a binder passage of the binder 13.

  After moving the curl guide 30, the feed roller 50a is rotated by a feed motor (not shown), and the binding tool 13 sandwiched between the feed roller 50a and the driven roller 50f biased by the spring 50g is pulled out from the bobbin 52 by about 80 mm. To the tie slope 63. At this time, the binding tool 13 advances through the step passage structure 60 constituted by the left approach arm 61a, the connect block 31a, the curl guide 30, the right connect block 31b, and the approach arm 61b.

  After feeding the binding tool 13 to the tie slope 63, the moving motor 93 is rotated again, and the ball screw shaft 94 is rotated via the gears 93a and 94a. The operation plate 32 is further slid in the direction of the arrow Q2 by the rotation of the ball screw shaft 94, and the link roller 97 is pushed forward by the roller arm 101 attached to the lower end portion of the operation plate 32.

The right approach arm 61b also rotates clockwise. Accordingly, the left and right approach arms 61a and 61b are closed, and the left and right approach arms 61a and 61b bring both ends of the binding tool 13 'toward the torsion arm 70 to restrict the shape of the binding tool 13' to a U shape. .

  The torsion arm 70 holds the front end portion and the rear end portion of the binding tool 13 ′ by an S-shaped portion 70 a provided at the front end. The torsion arm 70 is rotated a plurality of times by a torsion motor 70c (not shown) with the S-shaped portion 70a holding the front end portion and the rear end portion of the binding tool 13 '. Thereby, the binding tool 13 ′ is fastened to the fold fold opening of the bag 14.

  In this binding machine 100, after fastening the binding tool 13 ', the close-up motor 93 is rotated in the reverse direction, and the ball screw shaft 94 is rotated in the reverse direction via the gears 93a and 94a. The operation plate 32 screwed to the ball screw shaft 94 is slidably moved in the direction of the arrow Q3. In response to the operation of the operation plate 32, the curl guide 30 moves in a direction away from the opposing binding tool forming mechanism 6A and releases the guide plate mechanism 8A pushed into the binding tool forming mechanism.

  Further, the contact between the roller arm 101 attached to the lower end portion of the operation plate 32 shown in FIG. 7 and the link roller 97 is released. Between the link roller 97 and the locking shaft 97 ′, a tension spring 122 that urges the link roller 97 constantly toward the locking shaft 97 ′ is stretched, and the roller arm 101 and the link roller are urged. When the contact with 97 is released, the link roller 97 moves in the direction of the arrow Q3. The link roller 97 is pushed back through the cutter link 62c coupled to the cutter 62.

  When the link roller 97 moves in the direction of the arrow Q3, the cutter 62 linked to the link roller 97 is retracted from the tie slope 63 of the bundling conveyance mechanism 5A. Simultaneously with the retracting process of the cutter 62, the left approach arm 61a linked to the link roller 97 rotates clockwise, and at the same time, the sector gear 97a also rotates clockwise and meshes with the sector gear 97a. The connected gear 96a is rotated counterclockwise.

  When the connecting gear 96a rotates counterclockwise, the connecting gear 96b rotates clockwise, and the sector gear 97b meshed with the connecting gear 96b rotates counterclockwise and is attached to the sector gear 97b. The right approach arm 61b is also rotated counterclockwise. Accordingly, the left and right approach arms 61a and 61b are opened, and the left and right approach arms 61a and 61b again form the step passage structure 60.

  Thereafter, the tag transport mechanism 4A pulls out one tag 1A accommodated therein and transports it to the curl guide 30 of the tag hold mechanism 3A. As a result, the binding machine 100 returns to the standby state shown in FIG.

  FIG. 8 is a top view showing a configuration example (before binding) and an operation example of the main part in the binding machine 100, and the tag holder mechanism 3A, the binding tool forming mechanism, and the binding tool of the binding machine 100 in the standby state shown in FIG. It is the top view which extracted 7 A of fastening mechanisms.

  According to the binding tool forming mechanism 6A shown in FIG. 8, in order to operate the cutter 62, cutter links 62a to 62c, link pins 97c and 97d, and a fixed shaft 97e are provided. The cutter 62 is rotatably attached by a support shaft 62 'provided at a corner of an L-shaped cutter link 62c. A spring shaft 104 is attached to one end of the cutter link 62c.

  A helical spring 123 is wound around the spring shaft 104. One end side of the helical spring 123 is engaged with the cutter 62, and the other end side is engaged with the support shaft 62 '. As a result, the cutter 62 is constantly urged counterclockwise by the helical spring 123 around the support shaft 62 ′ as the center of rotation.

  The other end of the cutter link 62c is rotatably attached to one end of the cutter link 62b by a link pin 97d.

  A substantially center portion of the cutter link 62b is fixed to the main body chassis portion 92 (see FIG. 1) by a fixed shaft 97e and is rotatably attached. The other end of the cutter link 62b is rotatably attached to one end of the cutter link 62a by a link pin 97c. The other end of the cutter link 62a is rotatably coupled to a V-shaped approach arm 61a via a link roller 97. A trough portion of the approach arm 61a is rotatably attached to the main body chassis portion 92 by a pin 105a. A sector gear 97a fixed to the trough of the approach arm 61a is also rotatably attached to the main body chassis 92 by a pin 105a.

  Also, one end (rear end) of the right L-shaped approach arm 61b is rotatably attached to the main body chassis portion 92 by a pin 105b. A sector gear 97b fixed to the rear end of the approach arm 61b is also rotatably attached to the main body chassis portion 92 by a pin 105b. With this configuration, when the link roller 97 is pushed in the direction of the arrow Q2, the cutter links 62a to 62c are linked around the fixed shaft 97e, and the cutter 62 is inserted into the binding tool 13 from the tie slope 63. .

  FIG. 9 is a top view showing a configuration example (after binding) of the main part of the binding machine 100 and an operation example thereof. According to the binding machine 100 shown in FIG. 9, the link roller 97 is pushed in the direction of the arrow Q2, and the cutter link 62a coupled to the link roller 97 is pushed up. The cutter link 62b linked to the pushed-up cutter link 62a by the link pin 97c rotates counterclockwise about the fixed shaft 97e.

  The cutter link 62c coupled to the cutter link 62b rotated counterclockwise by the link pin 97d is pushed down. As a result, the cutter 62 linked to the cutter link 62c is also pushed down, and the cutter 62 is inserted into the tie slope 63 of the binding tool 13 to cut the binding tool 13 existing in the tie slope 63.

  7, the left approach arm 61a linked to the link roller 97 simultaneously with the operation of the cutter 62 rotates counterclockwise about the pin 105a, and at the same time, the sector gear 97a. Also rotates counterclockwise, and the connecting gear 96a meshed with the sector gear 97a rotates clockwise. When the connection gear 96a rotates clockwise, the connection gear 96b rotates counterclockwise, and the sector gear 97b meshed with the connection gear 96b rotates clockwise and is attached to the sector gear 97b. The right approach arm 61b also rotates clockwise around the pin 105b. Accordingly, the left and right approach arms 61a and 61b are closed, and the left and right approach arms 61a and 61b can be brought close to the torsion arm 70 between the front end portion and the rear end portion of the binding tool 13 '.

  Subsequently, a configuration example and an operation example of the tag transport mechanism 4 </ b> A will be described with reference to FIGS. 10 and 11. 10A and 10B are perspective views showing a configuration example of the tag transport mechanism 4A. The tag transport mechanism 4A shown in FIG. 10A includes a cartridge 40 and a tag feed unit 41. The cartridge 40 constitutes an example of a tag storage unit, and a plurality of tags 1A are stored in the cartridge 40 in a state where the tags 1A are stacked. The cartridge 40 is inserted obliquely from the rear end side of the tag feeding portion 41 and attached to the tag feeding portion 41.

  The tag feed unit 41 includes a tag feed roller 41a and a tag feed motor 41b. In this example, the tag feed roller 41a includes a roller rotation shaft 41d and two roller rings 41e. Two roller rings 41e are press-fitted into the roller rotation shaft 41d, and are fixed at intervals. A gear 41c is attached to one end of the roller rotation shaft 41d. The material of the roller ring 41e is, for example, a rubber material. Of course, a material other than a rubber material may be used as long as the material has a large frictional force with the tag 1A.

  The tag feed roller 41a is rotatably attached to the front of the bottom surface of the tag feed unit 41 so that the roller rotation shaft 41d is perpendicular to the feed direction of the tag 1A housed in the cartridge 40. At this time, the roller ring 41e press-fitted into the roller rotation shaft 41d is in contact with the lowermost tag 1A of the cartridge 40.

  A tag feed motor 41 b is attached to the side surface of the tag feed unit 41. A gear 41c of the tag feed roller 41a is engaged with the tag feed motor 41b. With this configuration, the tag feed motor 41b rotates to rotate the tag feed roller 41a and feed the bottom tag 1A stored in the cartridge 40 one by one. For example, a stepping motor is used as the tag feed motor 41b.

  The tag feeding unit 41 includes a tag feeding guide 42. The tag feed guide 42 functions as an example of a guide unit, and guides the tag 1A sent by the tag feed unit 41. The tag feed guide 42 includes left and right guide flaps 42a and 42a, an operation pin 42b, and a rotation shaft 42d. The left and right guide flaps 42a, 42a constitute an example of first and second door members, and are attached to be freely opened and closed.

  In this example, the guide flaps 42 a and 42 a have a curved shape that forms an arc projecting outward so as to constitute the tag transport path I. The curved guide flaps 42a and 42a include links 42e and 42f. The link 42e is provided on the upper wall surface of the guide flaps 42a and 42a, and the link 42f is provided at one end of the link 42e with a predetermined angle. A rotating shaft 42d is attached to the joint between the link 42e and the link 42f.

  An operation pin 42b is attached to the tip of the link 42f. Also, a tension spring pin 42g is attached to the link 42e, and a tension spring 42h (see FIG. 11B) is attached to the pin 42g. The tension spring 42h pulls the left and right guide flaps 42a, 42a so that the links 42e face each other. The guide flaps 42a and 42a shown in FIG. 10A are in a closed state. In this state, the guide flaps 42 a and 42 a guide the tag 1 </ b> A sent by the tag sending unit 41 along the curved shape forming the tag transport path I.

  The guide flaps 42a and 42a shown in FIG. 10B are in an open state. Thus, in order to open the guide flaps 42a and 42a, the operating pin 42b is pushed out in the direction of the arrow Q3 shown in FIG. 10B (the same direction as the arrow Q3 shown in FIG. 7). When the operating pin 42b is pushed in the direction of the arrow Q3, the left and right guide flaps 42a and 42a move so as to be separated from each other about the rotation shaft 42d. At this time, the left and right guide flaps 42a and 42a are pulled by the tension spring 42h so as to approach the left and right guide flaps 42a and 42a. Therefore, when the operating pin 42b pushed in the direction of the arrow Q3 is released, the left and right guide flaps 42a and 42a approach each other due to the force of the tension spring 42h, and the closed state shown in FIG. 10A is restored. In this way, the left and right guide flaps 42a and 42a open and close.

  FIGS. 11A and 11B are perspective views showing an example of conveyance of the tag 1A by the tag conveyance mechanism 4A. The tag transport mechanism 4A shown in FIG. 11A has a tag 1A in which the mounting portion 11A of the tag 1A is guided in the substantially vertical direction by the guide flaps 42a and 42a of the tag feed guide 42 of the tag transport mechanism 4A shown in FIG. 10B. Further, the curl guide 30 is arranged.

  In this example, the mounting portion 11 </ b> A of the tag 1 </ b> A is between the L-shaped tag support member 30 e attached so as to extend forward of the curl guide 30 and the tag hooking claws 30 b and 30 b of the curl guide 30. Be guided to. That is, the recesses 12m and 12m provided below the mounting portion 11A of the tag 1A are arranged in front of the tag hooking claws 30b and 30b of the curl guide 30.

  In a state where the recesses 12m, 12m of the tag 1A are arranged in front of the tag hooking claws 30b, 30b of the curl guide 30, the curl guide 30 slides (advances) as shown in FIG. 11B. Accordingly, the recesses 12m and 12m of the tag 1A are hooked on the tag hooking claws 30b and 30b of the curl guide 30, and the mounting portion 11A of the tag 1A can be held by the tag support member 30e. Further, when the curl guide 30 moves forward, the operating pin 42b that has fallen into the recess 30a of the curl guide 30 is pushed forward and pushed up, and the left and right guide flaps 42a and 42a are rotated and opened. As a result, the tag 1A held by the curl guide 30 can pass through the openings of the left and right guide flaps 42a, 42a. In this way, the tag 1A guided by the guide flaps 42a and 42a of the tag feed guide 42 is conveyed.

  FIG. 12 is a perspective view showing a configuration example of the curl guide 30 in the tag holder mechanism 3A. The tag holder mechanism 3 </ b> A shown in FIG. 12 has a curl guide 30.

  The curl guide 30 has a main body portion 301 that forms a T-shaped block, and a pair of tag hooking claw portions 30b and 30b that constitute the function of the claw portion are provided at the lower front portion of the main body portion 301. The mounting portion 11A formed on 1A is caught. The mounting portion 11A constitutes an alignment portion for the tag 1A.

  At the same time, the curl guide 30 has a curved guide projection 30c on the front surface of the main body 301, and the curved guide projection 30c is provided with a groove-like binding tool passage 303. On the front upper part of the curl guide 30, hook-shaped projections 30d, 30d are provided, and the mounting portion 11A of the tag 1A is located between the tag hooking claws 30b, 30b and the upper hook-shaped projections 30d, 30d. Fitted. The curling guide 30 aligns the binding tool passage 303 and the locking holes 11m, 11m of the tag 1A in a self-aligning manner, and passes the binding tool 13 from one locking hole 11m to the other locking hole 11m. Made. The front side of the binder passage 303 is open.

  A tag support member 30e constituting the tag support mechanism 2A is provided at a predetermined portion from the upper part of the curl guide 30 to the binding tool passage 303 so as to support the upper end of the tag 1A when the tag is transported. For the tag support member 30e, a metal or a resin component obtained by processing a member main body into an L shape is used. In this example, a concave portion 304 for attaching a tag support is provided on the top end of the curl guide 30, and a tag support member 30 e is attached to the concave portion 304 and fixed with screws 302. The L-shaped portion of the tag support member 30e is attached in a posture facing the tag entry direction. This is to prevent rotation of the tag 1A at the tip of the L-shaped portion of the tag support member 30e.

  FIG. 13 is a side view showing a configuration example of the curl guide 30 when the tag support is attached.

  According to the curl guide 30 shown in FIG. 13, the angle θ is set to θ = 90 ° + α, where θ is the angle at which the member main body forms an L shape in the tag support member 30e and α is the margin angle. The curl guide 30 can support the tag 1A with good reproducibility. The margin angle α is for facilitating removal of the tag 1A from the curl guide 30 after binding. The margin angle α is set to about 5 ° to 45 °, for example.

  14 and 15 are perspective views showing a comparative example (support / non-support) regarding the tag support member 30e in the curl guide 30. FIG.

  The curl guide 30 shown in FIG. 14 is a case where a tag support member 30e is attached (there is a tag support member 30e). In this case, the tag 1A is held at the three points of the pair of tag hooking claws 30b and 30b and the tag support member 30e. If the tag support mechanism 2A is configured in this way, the rotation of the tag 1A around the tag hooking claws 30b, 30b is prevented.

  On the other hand, the curl guide 30 shown in FIG. 15 is a case where the tag support member 30e is removed (there is no tag support member 30e). That is, the screw 302 at the top of the curl guide 30 shown in FIG. 14 is loosened and opened, and the tag support member 30e is removed from the recess 304. In this case, it was confirmed that the tag 1A is easily rotated and dropped with the tag hooking claws 30b and 30b as the center of rotation.

  This is a case in which the tag 1A is conveyed toward the guide plate 95 by the curl guide 30, and the tag of the curl guide 30 is placed in the slanted concave portions 12m and 12m (notches) of the tag 1A shown in FIG. When the hooking claw 30b is to be hooked, the rear end of the tag 1A is pulled out by the curl guide 30 from the state sandwiched between the tag feed rollers 41a of the tag feed unit 41 shown in FIG. For this reason, the tag 1A is inclined. As a result, the tag 1A rotates about the pair of tag hooking claws 30b, 30b of the curl guide 30, and the phenomenon that the tag 1A falls off from the curl guide 30 occurs.

  In this example, in order to prevent this phenomenon, the tag support member 30e is attached to the recess 304 for attaching the tag support provided at the upper end of the curl guide 30 so that the L-shaped portion faces downward. Is.

  Thus, according to the binding machine 100, the band-shaped cut binding tool 13 'is wound around the fold fold of the bag 14 using the two locking holes 11m and 11m provided in the tag 1A, and the tag When attaching 1A to the fold fold of the bag 14, a tag support member 30e is provided at the upper end of the curl guide 30 and functions to be hooked on the upper part of the tag.

  Therefore, the tag 1A can be prevented from rotating around the tag hooking claws 30b and 30b. As a result, it is possible to prevent the tag from falling off due to the rotation of the tag as compared with the case where the tag support member 30e is not attached. Further, the binding tool 13 inserted from the locking hole 11m of one tag 1A can be pulled out from the other locking hole 11m with good reproducibility. Moreover, the tag 1A can be smoothly pulled out from the tag transport mechanism 4A after binding, and a highly reliable binding machine 100 can be provided.

  FIG. 16 is a perspective view seen from below showing an example of attachment of the tag support member 42c in the tag transport mechanism 4A. In this example, a tag support member 42c is installed on the downstream side of the tag feed roller 41a to support the tag rear end.

  The tag transport mechanism 4A shown in FIG. 16 has a tag support function, and transports the tag 1A to the tag hold mechanism 3A. For example, the tag transport mechanism 4A has a tag transport path I and a feed roller 41a, and transports the tag 1A to the tag hold mechanism 3A through the tag transport path I.

  The tag transport mechanism 4A is provided with a tag support member 42c that constitutes another tag support mechanism 2A, and holds the rear end portion of the tag 1A. For example, the tag support member 42c is disposed at a portion from the lower part of the guide flaps 42a and 42a of the tag transport mechanism 4A to the tag transport path I. In this example, the tag support member 42c is disposed in a portion from the position detouring outside the feed roller 41a to the tag transport path I.

  For the tag support member 42c, a metal or resin component obtained by processing a main body member into a tongue shape is used. For example, an elongated iron plate having a predetermined thickness is mountain-folded at right angles to define a first bent portion 401 in the member body, and further, a second bent portion in which a portion extending from the portion is rounded and valley-folded. The one folded so as to define the portion 402 is used. Thus, the rear end portion of the tag 1A can be supported and placed until the curl guide 30 reaches the guide plate 95.

  FIGS. 17 and 18 are configuration transition diagrams showing functional examples (parts 1 and 2) of the tag transport mechanism 4A and the tag hold mechanism 3A. FIG. 19 is a perspective view that supplements an example of conveying a tag 1A of another size.

  FIG. 17A is a side view of the curl guide 30 partially cut away to show a standby example at the home position HP. In FIG. 17A, the home position HP of the curl guide 30 is a state in which the guide flaps 42a, 42a of the tag transport mechanism 4A are closed, and the curl guide 30 is moved away from the guide plate 95 and moved to the leftmost side. In other words, a position where the front end of the curl guide 30 is waiting on the upper extension line of the guide flaps 42a, 42a in the closed state.

  FIG. 17B is a side view of the flap partially broken showing an example of tag loading at the home position HP of the curl guide 30. According to the tag transport mechanism 4A shown in FIG. 17B, the tag 1A is loaded while the curl guide 30 stands by at the home position HP. At this time, the tip of the tag 1A is supported by the tag support member 30e of the curl guide 30.

  In this example, the tag 1A housed in the cartridge 40 of the tag transport mechanism 4A is sent out by the tag feed roller 41a. The curl guide 30 slides on the tag 1A fed by the tag feed roller 41a by hooking the concave portions 12m and 12m of the tag 1A shown in FIG. Operates to move (forward).

  At this time, the tag 1A is completely fed out of the cartridge 40 by the tag feed roller 41a, and the rear end portion of the information presentation unit 10A of the tag 1A is supported by the tag support member 42c. The tag support member 42c can prevent the tag 1A from dropping when the curl guide 30 moves forward. The guide flaps 42a and 42a are not shown in order to facilitate the explanation of the conveyance of the tag 1A.

  FIG. 18A is a side view showing an example of tag conveyance from the home position HP of the curl guide 30 to the guide plate 95 of the binding tool fastening mechanism 7A. According to the tag transport mechanism 4A shown in FIG. 18A, the guide flaps 42a and 42a are opened, and the curl guide 30 of the tag hold mechanism 3A starts to move to the right side, toward the guide plate 95 of the binder fastening mechanism 7A. Is moved (guided). At this time, even after the tag feed roller 41a is detached from the tag 1A, the tag 1A is supported by the tag support member 42c. In FIG. 18A, II is the moving direction of the curl guide 30.

  According to the tag hold mechanism 3 </ b> A shown in FIG. 18B, the curl guide 30 is brought into contact (reached) with the guide plate 95. At this time, the front end portion of the tag 1A is supported by the tag support member 30e and the guide plate 95 of the curl guide 30, and the rear end portion of the tag 1A is supported obliquely by the tag support member 42c of the tag transport mechanism 4A. The From this point in time, the tag 1A is held by the tag hooking claws 30b, 30b of the curl guide 30 and the guide plate mechanism 8A that are in contact with the tip of the guide plate mechanism 8A.

  Thereby, dropping off of the tag 1A can be prevented. After that, the tag 13A is held by the tag hooking claws 30b and 30b of the curl guide 30 and the guide plate mechanism 8A, and the binding tool 13 is transported toward the tag 1A by the binding tool transport mechanism 5A shown in FIG. Is done.

  Thus, by holding the tag 1A diagonally, the tag 1A can be pulled out from the tag transport mechanism 4A without dropping the tag 1A by the curl guide 30. In addition, since the tip of the tag 1A is supported by the tag support member 30e and the guide plate 95 of the curl guide 30, it is possible to prevent the tag 1A from falling off the curl guide 30.

  FIG. 19 is a perspective view that supplements an example of conveying another tag 1A ′. The curl guide 30 is moved in the movement direction II shown in FIG. According to the tag hold mechanism 3A shown in FIG. 19, the case where the length of the tag 1A ′ is shorter than the length (normal length) of the tag 1A shown in FIG. Also in this case, since the rear end portion of the tag 1A is supported by the tag support member 42c of the tag transport mechanism 4A, the tag 1A shorter than the normal length shown in FIG. 16 can be completely removed from the tag feed roller 41a. The recoil when the tag is detached can be suppressed by the tag support member 42c, and the tag 1A can be prevented from falling off.

  Thus, according to the binding machine 100, the tag transport mechanism 4A includes the tag support member 42c, and when the tag 1A is transferred from the tag transport mechanism 4A to the tag hold mechanism 3A, the tag support member 42c causes the rear end of the tag 1A. The opening time can be delayed.

  Accordingly, as shown in FIG. 19, even when handling a tag 1A that is shorter than a normal length, etc., it is possible to prevent a drop due to a tag delivery error as compared with the case where the tag support member 42c is not attached. As a result, the tag 1A can be transferred from the tag transport mechanism 4A to the tag holder mechanism 3A with good reproducibility regardless of whether the tag 1A is long or short, and a highly reliable binding machine 100 can be provided. It was. As a result, the tag 1A can be transported from the tag holder mechanism 3A to the binding tool fastening mechanism 7A with good reproducibility.

  FIG. 20 is a top view illustrating an external configuration example of the binding machine 100. In this example, a guide space region (bag converging groove) extending from the binding port 103 of the binding machine 100 to the mounting space portion 92b is provided so as to prevent binding defects due to the protruding of the bag 14. A binding machine 100 shown in FIG. 20 includes an intermediate chassis portion 92a, a substrate 92i for mounting a binding tool forming mechanism, and a top plate 19 on a main body chassis portion 92.

  In this example, a binding port 103 is set at a lower portion of the upper surface plate 19 near the center, and the upper surface plate 19 is provided with an edge portion 901 for introducing a bag having an R shape. A triangular space region is formed by the edge portion 901 and the tip inclined portion 903 of the guide plate 95 of the guide plate mechanism 8A. This triangular space region is provided for inserting the bag toward the apex of the triangle when the bag is mounted. As a result, the bag mounting process can be executed by operating the guide plate 95 like a shutter.

  Note that one end of the edge portion 901 shown in FIG. 20 is linked to an R-shaped bag introduction portion 902 provided in the intermediate chassis portion 92a, and the other end of the edge portion 901 is the intermediate chassis of the guide plate mechanism 8A. It is comprised so that it may reach and connect with the front-end | tip part of the installation space part 92b of the part 92a (refer FIG. 21).

  FIG. 21 is a top view showing an example of the internal configuration of the binding machine 100. 22A and 22B are perspective views as seen from the rear surface side, showing a configuration example of the guide plate 95 and an attachment example thereof. The binding machine 100 shown in FIG. 21 is in a state in which the upper surface plate 19 is removed from the intermediate chassis portion 92a, and includes a binding tool fastening mechanism 7A, a movable guide plate mechanism 8A, and a tag hold drive mechanism 9A.

  The binding tool fastening mechanism 7A is provided in the intermediate chassis 92a and operates to attach the tag 1A to the bag 14 with the binding tool 13 passed through the binding tool passage 303 of the tag hold mechanism 3A. The binding tool fastening mechanism 7A has a mounting space 92b having a U-shape for inserting an object to be mounted. The mounting space 92b is provided on the bag mounting side at the intermediate chassis 92a. The binding tool fastening mechanism 7A is provided with a torsion arm 70 that constitutes an example of a rotating shaft so that the cut binding tool 13 'passed through the two locking holes 11m, 11m of the tag 1A is twisted and fastened. (See FIG. 23).

  Below the binding tool fastening mechanism 7A, a guide plate mechanism 8A as shown in FIG. 22A is attached to the intermediate chassis 92a and operates to guide the tag 1A and the bag 14 to the mounting space 92b. In this example, a pair of rail members 92g and 92h are arranged on the surface of the intermediate chassis portion 92a, and a U-shaped guide plate 95 as shown in FIG. Used in combination (see FIG. 23).

  The guide plate 95 is always urged toward the tag holder mechanism 3A. The guide plate 95 has a plate body 95a as shown in FIG. 22B, and is formed from a sheet metal member such as an iron plate. The plate body portion 95a is provided with a notch portion 95b for guiding the bag fold opening, an opening portion 95c, an opening portion 95d, and a projection 95e for attaching the spring.

  The cutout portion 95b has an opening width W (W ≧ w) that is greater than or equal to the width w of the mounting space portion 92b. This opening width W is because the fold opening of the bag 14 can be smoothly guided from the binding port 103 to the mounting space 92b. The notch 95b has a function of extending the length of the U-shaped flange of the mounting space 92b. In this example, when the bag is mounted, the length of the cutout portion 95b protruding from the front end of the mounting space portion 92b is added to the length of the U-shaped lip, so that the bag insertion port (shown in FIG. 20) is added. The length from the vicinity of the apex of the triangular area) to the mounting space 92b (depth of the converging groove) can be secured sufficiently.

  The opening 95 c is a rectangular hole for escaping the torsion arm 70. The opening 95 d is a rectangular hole for locking the guide plate 95. The protrusion 95e is formed by cutting a necessary portion of the plate main body 95a when the opening 95d is formed in the plate main body 95a and bending the portion, and a hole 904 for attaching a spring. And 905. A projecting portion 95f for sensor flag is provided at the rear end portion of the plate main body portion 95a, and a projecting portion 95g for position regulation is provided at the front end portion thereof.

  In addition to these, the plate main body portion 95a is provided with a pair of elongated holes 906 and 906 for escaping parts, elongated holes 907 and 907, elongated holes 908 and 908 for position regulation, and the like. In this example, the long holes 906 and 906 are openings that intersect with a space member (not shown) that fixes the bundling mechanism mounting substrate 92i to the pins 92e and 92f. The long holes 907 and 907 are openings that intersect the shaft portions of the sector gears 97a and 97b. The long holes 908 and 908 are openings that intersect the shafts of the coupling gears 96a and 96b.

  On the other hand, the middle chassis 92a is provided with two openings 92c and 92d so as to be aligned with the mounting space 92b shown in FIG. 22A. The opening 92 c is a hole for escaping the torsion arm 70, and the opening 92 d is a hole for restricting movement of the guide plate 95. A pin 92e and a pin 92f are attached to both sides of the opening 92c on the back surface of the intermediate chassis 92a. The pins 92e and 92f are made of metal bars. Ring grooves (not shown) for stabilizing and fixing springs are provided at the ends of the pins 92e and 92f.

  In this example, as shown in FIG. 22A, the guide plate 95 connects the hole portion 904 of the protruding portion 95e and the pin 92e with a spring spring 82a in a state where the protruding portion 95e is fitted in the opening 92d. 95e hole 905 and pin 92f are connected by spring spring 82b. Thereby, the guide plate mechanism 8A is obtained. When the guide plate mechanism 8A is configured in this way, the tag 1A is placed in the fold fold of the bag 14 inserted in the mounting space 92b in a posture (state) in which the curl guide 30 and the guide plate 95 hold the tag 1A. It can be transported.

  In addition to the guide plate mechanism 8A, the intermediate chassis 92a is provided with a tag holder drive mechanism 9A. The tag holder mechanism 3A is moved toward or away from the guide plate mechanism 8A, and the tag holder mechanism 3A is moved to the guide plate mechanism 8A. Drive to hit and push back.

  The above-mentioned guide plate mechanism 8A is provided with a lock mechanism 81 (see FIG. 23A). The lock mechanism 81 shown in FIG. 23A is provided on a half-moon flange-like (hereinafter simply referred to as half-moon) cam plate 99 provided on the torsion arm 70 of the binding tool fastening mechanism 7A, and on the guide plate 95 of the guide plate mechanism 8A. The cam engaging opening 95d. In this example, the half-moon shaped part is caught by the opening 95d according to the rotational position of the cam plate 99.

  For example, when the half-moon shaped part is at a position where the lower chord shape is formed with respect to the opening 95d, the half-moon shaped part is not caught by the opening 95d. This positional relationship is such that the guide plate 95 is not locked. On the other hand, when the cam plate 99 rotates 180 ° and the half-moon shaped portion shifts to a position where it becomes an upper chord shape with respect to the opening 95d, the half-moon shaped portion is caught by the opening 95d. This positional relationship is a state in which the guide plate 95 is locked.

  If the guide plate mechanism 8A is configured in this manner, the guide plate 95 can be locked by the cam plate 99, and the guide plate 95 can be prevented from jumping out immediately after being bound. Thereafter, the lock can be released by the rotation of the cam plate 99.

  In this example, a guide plate sensor 107 for a guide plate, which is an example of a detection means, is attached to a predetermined position on the back surface of the substrate 92i for attaching the binding forming mechanism shown in FIG. For example, the guide plate sensor 107 is disposed at a position where the sensor flag protrusion 95f of the guide plate 95 shown in FIG. 22A passes through the slit of the guide plate sensor 107 (see FIG. 23).

  As the guide plate sensor 107, a transmissive optical sensor is used. The guide plate sensor 107 detects the position of the opening 95d of the guide plate 95 with respect to the half-moon-shaped cam plate 99 of the binder fastening mechanism 7A and outputs position information. When such a guide plate sensor 107 is provided, the position of the guide plate 95 can be grasped by the control unit 110 that constitutes the function of the control means, so that the guide plate delay return function can be controlled.

  For example, when the opening 95d of the guide plate 95 is located in front of the half-moon cam plate 99 of the binding tool fastening mechanism 7A, the guide plate 95 is biased by a spring or the like and protrudes in the direction of the tag hold mechanism 3A. State. When the opening 95d of the guide plate 95 is located at the same position as the cam plate 99 of the binder fastening mechanism 7A, the guide plate 95 is pushed by the tag holder mechanism 3A and overcomes the urging force of a spring or the like, and the guide plate mechanism 8A side Is in a state of being retracted. Thereby, it can be confirmed by the position of the guide plate 95 whether or not the fold opening of the bag 14 has been properly set in the mounting space 92b.

  The binding tool 100 shown in FIG. 21 is provided with a control unit 110, and the binding tool fastening mechanism 7A twists the binding tool 13 ′ after cutting passed through the two locking holes 11m and 11m of the tag 1A. When fastening, the tag 1A is fastened by twisting the binding tool 13 'after cutting at an integral number of times and approximately 1/2 rotation, and the cam plate 99 of the binding tool fastening mechanism 7A is guided by the remaining approximately 1/2 rotation. The binding tool fastening mechanism 7A is controlled so as to engage with the 95 openings 95d. For example, 2.5 times, 3.5 times, 4.5 times, etc. are set as integer times, and the motor is turned on at integer times and turned off at 0.5 times. When such a control unit 110 is provided, a guide plate delay return function can be realized.

  Here, the guide plate delay return function locks the movement of the guide plate 95 even after the bundling process on the bag 14 is completed, and stops the control unit 110 without moving to the next step. This is an operation of returning the guide plate 95 with a delay as compared with the case where the function is not provided.

  This guide plate delay return function is for shortening the distance that the bag 14 after binding is pulled out from the mounting space portion 92b to facilitate the removal of the bag 14 from the mounting space portion 92b. Thus, the guide plate 95 can be locked by the cam plate 99, and the guide plate 95 can be prevented from popping out immediately after being bound. Thereafter, the lock can be released by the rotation of the cam plate 99.

Subsequently, functional examples of the tag holder mechanism 3A and the guide plate mechanism 8A will be described. 23 to 25 are top views showing functional examples (parts 1 to 3) of the tag holder mechanism 3A and the guide plate mechanism 8A.
FIG. 23A is a top view showing an example of a positional relationship during standby of the tag holder mechanism 3A and the guide plate mechanism 8A.

  According to the example of the positional relationship during standby of the tag holder mechanism 3A and the guide plate mechanism 8A shown in FIG. 23A, the separation distance L1 is set (defined) between the tip portion of the curl guide 30 and the tip portion of the guide plate 95, and the guide A separation distance L2 is set (defined) between the rear end portion of the position restricting projection 95g of the plate 95 and the front end portion of the rail member 92h. The separation distance L2 is generated when the guide plate 95 is urged by the spring springs 82a and 82b shown in FIG. 22A.

  In this configuration, when the guide plate 95 is pushed rightward, the guide plate 95 can be retracted until it abuts against the tip of the rail member 92h. That is, the guide plate 95 is always urged forward by the spring springs 82a and 82b and is retracted when pressed. In the standby state of the tag holder mechanism 3A and the guide plate mechanism 8A, the tag 1A is held by the tag hooking claws 30b and 30b of the curl guide 30. At this time, since the sensor flag protrusion 95f does not cross the slit of the guide plate sensor 107, for example, high level (hereinafter referred to as “H” level) position detection data D6 is output to the control unit 110.

  The standby position of the binding tool fastening mechanism 7A is when the half-moon shaped part of the cam plate 99 is in a position where it becomes a lower chord shape with respect to the opening 95d, and the half-moon shaped part is not caught by the opening 95d. It is. This standby position is a state where the guide plate 95 is not locked.

  FIG. 23B is a top view showing an example of a positional relationship when the tag holder mechanism 3A is in contact with the guide plate mechanism 8A. According to the positional relationship example shown in FIG. 23B, the tag holder drive mechanism 9A moves the curl guide 30 shown in FIG. 23A from the standby state in the previous period and moves it by the separation distance L1. By this previous movement, the tip of the curl guide 30 comes into contact with the tip of the guide plate 95 via the tag 1A. That is, the tag 1A is sandwiched between the guide plate 95 and the curl guide 30, and the tag 1A can be prevented from falling off. Thereafter, in this state, the tag 1A is moved to the mounting space 92b.

  Note that the separation distance L2 does not change at the time of contact. This is because the guide plate 95 is biased by the spring springs 82a and 82b shown in FIG. 22A. Further, since the guide plate sensor 107 does not cross the protruding portion 95f, the position detection data D6 of “H” level is still output. This "H" level position detection data D6 indicates that the guide plate 95 is free.

  FIG. 24A is a top view showing an example of the positional relationship when the tag holder mechanism 3A is pushed into the guide plate mechanism 8A. According to the positional relationship example shown in FIG. 24A, the tag holder drive mechanism 9A further moves the curl guide 30 from the position shown in FIG. 23B to move the separation distance L2 further. In this example, the guide plate 95 is pushed by the tag hooking claws 30b and 30b. With this later movement, the rear end portion of the protruding portion 95g of the guide plate 95 is in contact with the front end portion of the rail member 92h while the front end portion of the curl guide 30 is in contact with the front end portion of the guide plate 95. . At this time, the conveyance to the mounting space 92b of the tag 1A is completed.

  At this time, the sensor flag projection 95f shields light across the slit of the guide plate sensor 107, and therefore, for example, low level (hereinafter referred to as “L” level) position detection data D6 is sent to the control unit 110. Output. Thereafter, the control unit 110 uses the position detection data D6 as a trigger to drive the tag holder driving mechanism 9A, and the binding tool forming mechanism 6A forms the cut binding tool 13 ′, and the binding tool fastening mechanism 7A uses the torsion arm 70 of the binding tool fastening mechanism 7A. The tag 1A is bound by the binding tool 13 ′ after cutting.

  FIG. 24B is a top view showing an example of the positional relationship of the cam plate 99 of the guide plate mechanism 8A at the end of binding in the binding machine 100. FIG. When the bundling process is completed, the control unit 110 operates the lock mechanism 81 in FIG. 24B. For example, in the lock mechanism 81, the half-moon shaped cam plate 99 provided on the torsion arm 70 of the binding tool fastening mechanism 7A stops at a position rotated 180 ° from the standby state.

  By this rotation, the cam plate 99 stops at a position where it is caught by a cam engaging opening 95d provided in the guide plate 95. That is, the half-moon-shaped part of the cam plate 99 is stopped in a posture that forms an upper chord shape with respect to the opening 95d, and the cam plate 99 is caught by the opening 95d to lock the urging force toward the front side of the guide plate 95. Since the guide plate sensor 107 remains shielded from light by the protruding portion 95f, it outputs “L” level position detection data D6. This “L” level position detection data D6 indicates that the guide plate 95 is locked.

  FIG. 25 is a top view showing an example of the positional relationship of the cam plate 99 in the guide plate mechanism 8A when the tag holder mechanism 3A is returned. The control unit 110 controls the curl guide 30 to return to the standby position by driving the tag holder drive mechanism 9A while operating the lock mechanism 81 shown in FIG. At this time, even if the curl guide 30 is retracted to the standby position, the urging force of the spring springs 82a and 82b is overcome and the return of the guide plate 95 is suppressed while the half-moon shaped portion of the cam plate 99 is caught by the opening 95d. It is in a state.

  Since the guide plate 95 is locked by the cam plate 99 even after the curl guide 30 is retracted, it does not pop out. Thus, the bundled bag 14 can be easily taken out with the guide plate 95 locked. Since the guide plate sensor 107 remains shielded from light by the projecting portion 95f, the position detection data D6 of “L” level is output (the lock mechanism remains active).

  As described above, according to the binding machine 100, the band-shaped cut binding tool 13 'is wound around the fold fold of the bag 14 using the two locking holes 11m and 11m provided in the tag 1A, and the tag 1A Is attached to the fold fold opening of the bag 14, the movable guide plate mechanism 8 A having a notch 95 b is provided, and the tag 1 A is held by the tag hold mechanism 3 A and the guide plate 95, and the mounting space 92 b The tag 1A can be conveyed to the fold opening of the bag 14 inserted into the bag 14.

  Therefore, it is possible to prevent the tag 1A from dropping off during the tag conveyance. Moreover, since the notch portion 95b for guiding the bag fold fold extends from the mounting space portion 92b to the outside, the fold fold opening of the bag 14 is inserted into the mounting space portion 92b accurately before carrying the tag. become able to. As a result, a highly reliable tag attaching device or the like can be provided.

  FIG. 26 is a top view showing an example of a step passage structure in the binding machine 100. In this example, a case in which a passage through which a binding tool 13 such as a twist tie, a string, and a wire passes is constituted by a plurality of parts is taken as an example. A binding machine 100 shown in FIG. 26 includes a tag holder mechanism 3A, a binding tool forming mechanism 6A, a tag holder driving mechanism 9A, and a step passage structure 60. The tag holder mechanism 3A has a binding tool passage 303 at a position indicated by a broken line in the curl guide 30 in the drawing, and the binding tool 13 is passed through (see FIG. 12).

  In this example, a binding tool forming mechanism 6 </ b> A configured to abut the tip of the curl guide 30 is provided, and the binding tool 13 passed through the binding tool passage 303 is formed. The binding tool forming mechanism 6A includes binding tool guide paths 601 and 602 communicated with the above-described binding tool passage 303, an approach arm 61a (left side toward the binding tool forming mechanism 6A), and an approach arm 61b (same right side). )have. The approach arm 61a constitutes the function of a pivotable first shift arm, and is arranged on the left side of the binding tool forming mechanism 6A so that the end of the binding tool 13 'after cutting is moved from the left side to the center portion. The tag holder driving mechanism 9A operates by obtaining the driving force.

  The approach arm 61b constitutes the function of a rotatable second shift arm, and is arranged on the right side of the binding tool forming mechanism 6A so that the tip of the binding tool 13 'after cutting is moved from the right side to the center. The tag holder driving mechanism 9A operates by obtaining the driving force. As a result, the cut tying member 13 ′ passed through the two locking holes 11 m and 11 m of the tag 1 </ b> A can be molded by approaching the central portion by the approach arms 61 a and 61 b.

  In this example, a connect block 31 a is arranged between the approach arm 61 a and the curl guide 30, and guides the binding tool 13 to the binding tool passage 303 of the curl guide 30. In the approach arm 61a and the connect block 31a, the first binding tool guide path 601 is set in a portion through which the binding tool 13 passes and guides the tip of the binding tool 13.

  Further, a connect block 31b is disposed between the curl guide 30 and the approach arm 61b, and guides the binding tool 13 that has been pulled out (drawn out) from the binding tool passage 303 of the curl guide 30 to the approach arm 61b. In the connect block 31b and the approach arm 61b, a second binding tool guide path 602 is set in a portion through which the binding tool 13 passes and guides the distal end portion of the binding tool 13. The step guide structure 60 of the binding tool 13 is formed by the binding tool guide path 601, the binding tool path 303, and the binding tool guide path 602.

  In addition, on the upstream side of the binding tool guide paths 601, 602, a binding tool transport mechanism 5A is provided, and the two positions of the tag 1A locked by the tag hold mechanism 3A abutted against the binding tool forming mechanism 6A are locked. The holes 11m and 11m are guided by the binder passage 303 and the binder guide paths 601 and 602 so as to pass the binder 13 therethrough.

  Further, the binding tool fastening mechanism 7A described in FIG. 23 and the guide plate mechanism 8A described in FIG. 22 are attached to the space between the left and right approach arms 61a and 61b of the binding tool forming mechanism 6A. The guide plate mechanism 8A conveys the tag 1A to the fold fold opening of the bag 14 inserted into the mounting space 92b while the tag 1A is held by the curl guide 30 and the guide plate 95. The binding tool fastening mechanism 7A operates so as to twist and fasten the binding tool 13 'that has been cut close to the center by the binding tool forming mechanism 6A.

  In addition to driving the binder forming mechanism 6A, the tag holder driving mechanism 9A moves the tag holder mechanism 3A toward and away from the binder forming mechanism 6A, or pushes the tag holder mechanism 3A against the binder forming mechanism 6A. The operation is performed such that the binder passage 303 and the binder guide paths 601 and 602 communicate with each other.

  FIG. 27 is a partially broken top view showing an example of a step passage structure in the binding tool forming mechanism 6A. 28 to 30 are enlarged views showing step setting examples (parts 1 to 3) in the step passage structure 60. FIG.

  According to the step passage structure 60 of the binding tool forming mechanism 6A shown in FIG. 27, the binding tool guide paths 601 and 602 and the binding tool path 303 have a relatively high upstream guide surface in the entry direction of the binding tool 13 and the downstream side. The guide surface is set relatively low. 27 is set between the cutter 62 and the approach arm 61a, and an enlarged view thereof is shown in FIG. The cutter 62 is provided at the downstream end of the tie slope 63 (conveyance path) and operates to cut the binding tool 13.

  The step IIb shown in the figure is set as a communication connection between the approach arm 61a and the connection block 31a, and is set as a communication connection between the connection block 31a and the binding tool passage 303 of the curl guide 30. These enlarged views are shown in FIG. The stepped portion IIIc shown in the figure is set as a communication connection portion between the binding tool passage 303 of the curl guide 30 and the connect block 31b, and is set as a communication connection portion between the connect block 31b and the approach arm 61b. An enlarged view thereof is shown in FIG.

  According to the stepped portion Ia shown in FIG. 28, the downstream end of the cutter 62 is high, and the upstream end of the approach arm 61 a is set lower than the downstream end of the cutter 62. A first step ε1 is set between the upstream cutter 62 and the downstream approach arm 61a.

  According to the stepped portion IIb shown in FIG. 29, the downstream end of the approach arm 61a is high, and the upstream end of the connect block 31a is set lower than the downstream end of the approach arm 61a. A second step ε2 is set between the upstream approach arm 61a and the downstream connect block 31a.

  Further, the downstream end of the connect block 31a is high, and the upstream end of the binding tool passage 303 of the curl guide 30 is set lower than the downstream end of the connect block 31a. A third step ε3 is set between the connection block 31a and the binding tool passage 303 of the curl guide 30.

  According to the stepped portion IIIc shown in FIG. 30, the upstream end of the approach arm 61b is set lower than the downstream end of the binding tool passage 303 of the curl guide 30. A fourth step ε4 is set between the binding tool passage 303 of the curl guide 30 and the approach arm 61b.

  Further, the upstream end of the connect block 31b is set lower than the downstream end of the approach arm 61b. A fifth step ε5 is set between the connect block 31b and the approach arm 61b. In this manner, a total of five steps ε1, ε2, ε3, ε4, and ε5 are set.

  Even if each step ε1, ε2, ε3, ε4, ε5 is set to the same value, for example, about 1 to 2 [mm], each step ε1, ε2, ε3, ε4, ε5 is optimum individually. The values may be obtained and set individually. Further, an adjustment mechanism may be provided for each of the step portions Ia, IIb, and IIIc to individually adjust the steps ε1, ε2, ε3, ε4, and ε5.

  FIG. 31 is a top view of the binding tool forming mechanism 6 </ b> A showing an example of inserting the binding tool 13. According to the binding tool forming mechanism 6A shown in FIG. 31, on one side thereof, a rotatable approach arm 61a for bringing the cut binding tool 13 ′ toward the center and the binding tool 13 to the tag hold mechanism 3A. Connected guide blocks 31a are sequentially arranged, and the binder passage 303 of the curl guide 30 of the tag holder mechanism 3A is connected adjacent to the connect block 31a, and the other side of the binder forming mechanism 6A is adjacent to the binder passage 303. The connecting block 31b for guiding the binding tool 13 drawn out from the binding tool passage 303 and the rotatable approach arm 61b for bringing the binding tool 13 to the center are sequentially arranged.

  In this example, 13 inserted from the tie slope 63 is a step portion Ia of the binding tool guide path 601, and the step of the binding tool guide path 601 passes through the step ε 1 set between the cutter 62 and the approach arm 61 a. Transition to Part IIb.

  In the step portion IIb, the binding tool 13 from the approach arm 61a is set between the step ε2 set between the approach arm 61a and the connect block 31a and between the connect block 31a and the binding tool passage 303 of the curl guide 30. It moves to the level | step-difference part IIIc of the binding tool guidance path 602 through the level | step difference (epsilon) 3 made.

  In the stepped portion IIIc, the binding tool 13 that has come out from the downstream side of the binding tool passage 303 of the curl guide 30 is the step ε4 set between the binding tool path 303 and the approach arm 61b, and the connection block 31b and the approach arm. The approach arm 61b is reached through the step ε5 set between the first arm 61b and the second arm 61b. And the binding tool 13 is cut | disconnected by the cutter 62 provided in the downstream end part of the tie slope 63. FIG.

  As described above, according to the step passage structure 60 of the binding machine 100, the upstream guide surface is relative to each other with the binding tool guide paths 601 and 602 and the binding tool path 303 serving as communication connection portions in the entry direction of the binding tool 13. Therefore, the guide surface on the downstream side is set relatively low. In the above-described example, all the steps ε1, ε2, ε3, ε4, and ε5 are set lower on the downstream side than on the upstream side.

  Accordingly, the band-shaped cut binder 13 'is wound around the fold fold of the bag 14 using the two locking holes 11m, 11m provided in the tag 1A, and the tag 1A is wrapped around the fold fold of the bag 14. When attaching, the situation where the tip of the binding tool 13 hits the tip of the binding tool guide paths 601 and 602 can be avoided, so the binding tool forming mechanism 6A can be provided without providing a guide structure such as chamfering on the binding tool guide paths 601 and 602. Thus, the binding tool 13 can be smoothly inserted from the binding tool guide path 601 into the binding tool path 303 of the curl guide 30. Further, the binder 13 can be smoothly inserted from the binder passage 303 into the binder guide path 602 of the binder forming mechanism 6A. Thereby, the feeding failure of the binding tool 13 can be prevented.

  FIG. 32 is a block diagram illustrating a configuration example of a control system of the binding machine 100. The control system shown in FIG. 32 includes a control unit 110 and motor drive units 141b, 150i, 170c, and 193. The control unit 110 includes an I / O interface 111, a RAM 112, an EEPROM 113, a CPU 114, and a system bus 115. In addition, the tag feed motor 41b and the shifting motor 93 in the figure are the same as those shown in FIGS. The guide plate sensor 107 is the same as that shown in FIGS.

  An EEPROM (Electrically Erasable Programmable Read-Only Memory) 113 of the control unit 110 is connected to a CPU (Central Processing Unit) 114 via a system bus 115. The EEPROM 113 stores and stores a control program for the binding machine 100 and the like. After detecting that the bag 14 is attached to the binding port 103, this control program carries out processing to convey the tag 1A, send out the binding tool 13, and cut and twist the binding tool 13 passed through the tag 1A. It is something to be made.

  A RAM (Random Access Memory) 112 is connected to the CPU 114 via the system bus 115. When the binding machine 100 is powered on, the control program read from the EEPROM 113 is developed in the RAM 112 by the CPU 114.

  The CPU 114 is connected to the operation unit 106 via an I / O (Input / Output) interface 111, and inputs operation data D1 indicating the type of the tag 1A from the operation unit 106. The CPU 114 adjusts (changes) the feed amount of the tag 1A based on the operation data D1.

  Further, a guide plate sensor 107 is connected to the CPU 114 via the I / O interface 111, and position detection data D6 detected by the guide plate sensor 107 is output. The position detection data D6 is information indicating that the bag 14 is attached to the binding port 103.

  A bag sensor 108 is further connected to the CPU 114 via the I / O interface 111. The bag sensor 108 detects whether or not the bag 14 is placed at the binding port 103 by an arm 121 ′ (see FIG. 20) installed near the binding port 103. The CPU 114 inputs the bag detection data D7 detected by the bag sensor 108.

  A tag sensor 109 is connected to the CPU 114 via the I / O interface 111. The tag sensor 109 is provided in the tag transport path I of the tag transport mechanism 4A (see FIG. 10B). When the tag 1A is transported, the CPU 114 inputs transport data D8 indicating that the tag 1A is transported from the tag sensor 109. When the tag 1A is not transported, the CPU 114 inputs transport data D8 indicating that the tag 1A is not transported from the tag sensor 109. Based on the transport data D8, the CPU 114 outputs control data D2 for rotating the tag feed motor 41b to the motor drive unit 141b of the tag transport mechanism 4A.

  After inputting the position detection data D6 from the guide plate sensor 107, the CPU 114 outputs control data D3 for controlling the moving motor 93 to the motor drive unit 193 of the tag hold drive mechanism 9A. The motor driving unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the closing motor 93. The moving motor 93 rotates based on the motor control signal S3, and slides the operation plate 32 screwed to the ball screw shaft 94 shown in FIG. 7 in the direction of the arrow Q2 through the gears 93a and 94a. The curl guide 30 is moved from the home position HP to the binding position P1.

  After sliding the operation plate 32, the CPU 114 outputs the control data D4 for controlling the binder feed motor 50i of the binder transport mechanism 5A to the motor drive unit 150i. The motor drive unit 150i generates a motor control signal S4 from the control data D4 and outputs the motor control signal S4 to the binding tool feed motor 50i. The binding tool feed motor 50i rotates the binding tool feed roller 50a shown in FIG. 7 based on the motor control signal S4, pulls the binding tool 13 from the bobbin 52, and sends it to the tie slope 63.

  After sending the binding tool 13 to the tie slope 63 of the binding tool forming mechanism 6 </ b> A, the CPU 114 outputs control data D <b> 3 for controlling the closing motor 93 to the motor driving unit 193 again. The motor driving unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the closing motor 93. The moving motor 93 rotates based on the motor control signal S3, further slides the operating plate 32 shown in FIG. 7 in the direction of the arrow Q2, and is moved by the roller arm 101 attached to the lower end portion of the operating plate 32. Then, the link roller 97 is pushed to drive the cutter 62 and the approach arms 61a and 61b coupled to the link roller 97.

  After driving the cutter 62 and the approach arms 61a and 61b, the CPU 114 outputs control data D5 for controlling the torsion motor 70c to the motor driving unit 170c of the binding tool fastening mechanism 7A. The motor drive unit 170c generates a motor control signal S5 from the control data D5 and outputs it to the torsion motor 70c. The torsion motor 70c rotates the torsion arm 70 shown in FIG. 7 based on the motor control signal S5.

  After rotating the torsion arm 70, the CPU 114 outputs control data D <b> 3 for rotating the moving motor 93 in the reverse direction to the motor driving unit 193. The motor driving unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the closing motor 93. The moving motor 93 rotates in reverse based on the motor control signal S3, and slides the operating plate 32 shown in FIG. 7 in the direction of the arrow Q3 opposite to the arrow Q2 to move the curl guide 30 to the binding position P1. Return to home position HP.

  After returning the curl guide 30 to the home position HP, the CPU 114 outputs control data D2 for rotating the tag feed motor 41b to the motor drive unit 141b. In this example, the CPU 114 inputs the operation data D1 from the operation unit 106, and controls the delivery amount of the tag 1A based on the operation data D1. For example, when the operation data D1 indicating that the total length of the tag is long is input, the CPU 114 outputs the control data D2 for increasing the tag feed amount (for the long tag) to the motor driving unit 141b.

  In addition, when the operation data D1 indicating that the total length of the tag is short is input, the CPU 114 outputs the control data D2 for reducing the tag feed amount (for the normal tag 1A) to the motor driving unit 141b. The motor drive unit 141b generates a motor control signal S2 from the control data D2 and outputs it to the tag feed motor 41b. The tag feed motor 41b rotates based on the motor control signal S2, and rotates the tag feed roller 41a shown in FIG. 10A to feed out the lowermost tag 1A stored in the cartridge 40.

  In this example, due to the difference between the control data D2 for the long tag and the control data D2 for the normal tag 1A, in the case of the control data D2 for the long tag, the tag feed roller 41a is moved after the binding tool 13 is conveyed. The control is performed such that the rear end portion of the information presenting portion 10C of the long tag 1A ′ remaining in the cartridge 40 is sent out. Thereby, the said tag can be completely sent out according to the full length of a tag. After sending out one tag 1A, the CPU 114 waits for input of bag detection data D7 detected by the bag sensor 108.

  In addition to the method of inputting the operation data D1 from the operation unit 106 and controlling the feed amount of the tag, a method of detecting the full length of the tag 1A in real time and controlling the feed amount of the tag 1A is also conceivable. For example, a reflection type tag full length sensor 116 (not shown) is provided at a position for detecting a portion for discriminating the full length of the tag 1A (a tag protruding from the rear end portion of the cartridge 40), and the tag 1A conveyed by the tag conveyance mechanism 4A. You may make it detect the full length of.

  In this case, the tag full length sensor 116 detects the length of the long tag 1A 'longer than the tag 1A. The CPU 114 receives the detection data D9 from the tag full length sensor 116, determines the tag feed amount (rotation speed) of the tag feed motor 41b based on the detection data D9, and determines the tag feed motor 41b based on the discrimination result. Controls the amount of tag delivery.

  For example, when the tag full length sensor 116 detects the rear end portion of the tag 1A or the like, when the total length of the tag 1A or the like is long (when the length of the long tag 1A ′ longer than the tag 1A is detected), the tag 1A Detection data D9 indicating that the tag is longer than the total length is output to the CPU 114, and when the total length of the tag 1A is short, detection data D9 indicating that the tag total length is short is output.

  When the detection data D9 indicating that the total length of the tag is long is input, the CPU 114 outputs control data D2 (for a long tag longer than the tag 1A) to increase the tag feed amount to the motor drive unit 141b. As a result, it is possible to detect the entire length of the tag in real time and control the tag feed amount.

  Also in this example, due to the difference between the control data D2 for the long tag and the control data D2 for the normal tag 1A, in the case of the control data D2 for the long tag, the tag feed roller 41a is moved after the binding tool 13 is conveyed. The control is performed such that the rear end portion of the information presenting portion 10C of the long tag 1A ′ remaining in the cartridge 40 is sent out. Thereby, the said tag can be completely sent out according to the full length of a tag.

  In the above-described two examples, after one tag 1A is sent out, the position detection data D6 indicating whether or not the bag 14 is attached obtained from the guide plate sensor 107 may be input to the CPU 114. Thereafter, the CPU 114 waits for input of operation data D1 from the operation unit 106. In this way, the binding machine 100 can be controlled by the control program stored in the EEPROM 113.

  Here, the power supply of the binding machine 100 will be described. The power supply of the binding machine 100 includes a power supply circuit 20 that can be used by being connected to AC 100 V, for example. An AC switch 201 is connected between the AC power supply (100 V) and the power supply circuit 20, and the AC switch 201 is turned on when in use. The power supply circuit 20 has a power conversion function (not shown). For example, the power supply circuit 20 converts an AC power source into a main power source for driving a motor (for example, DC 12V) and a DC power source for low voltage that drives the control unit 110 (DC 5V). To be made. Here, the main power source of the binding machine 100 includes the motor driving unit 141b of the tag transport mechanism 4A, the motor driving unit 150i of the binding tool transport mechanism 5A, the motor driving unit 170c of the binding tool fastening mechanism 6A, and the motor drive of the tag holder driving mechanism 9A. A power supply for supplying a driving voltage to the unit 93 is referred to.

  In this example, a main switch 120 (relay switch or the like) is connected between the power supply circuit 20 and the motor drive unit 141b, and further, a bag sensor switch 121 (relay switch or the like) is connected to the load side of the main switch 120. The motor drive unit 150i, the motor drive unit 170c, and the motor drive unit 93 are connected. When the main switch 120 = ON, the driving voltage is supplied to the motor driving unit 141b, and when the bag sensor switch 121 = ON, the driving voltage can be supplied to the remaining motor driving unit 150i, the motor driving unit 170c, and the motor driving unit 93. Yes.

  In the main switch 120, the CPU 114 is turned on based on operation data D1 input from the operation unit 106, for example, information indicating D1 = “binding start”. In the bag sensor switch 121, the CPU 114 is turned on based on information indicating that the bag sensor 108 has bag detection data D7, for example, D7 = “bag present”. The reason for adopting such a double power supply measure is to consider safety for the user during handling.

  Next, a series of operation examples of the bundling process will be described step by step with reference to FIGS. FIG. 33 and FIG. 34 are flowcharts showing an operation example (parts 1 and 2) of the binding machine 100. FIGS. 35 to 41 are perspective views supplementing an operation example of the tag holder mechanism 3A and the guide plate mechanism 8A during tag conveyance.

  In this embodiment, the AC switch 201 of the binding machine 100 is turned on, and the control program stored in the EEPROM 113 of the control unit 110 shown in FIG. 32 is read by the CPU 114 and expanded in the RAM 112, and set to the power saving mode. ing. In the power saving mode, the main switch 120 and the bag sensor switch 121 shown in FIG. 32 are turned off, the driving voltage is not supplied to the motor driving units 141b, 150i, 170c, and 193, and the power source for low voltage is supplied to the control unit 110. The state being supplied to.

  Further, the tip of the binding tool 13 wound around the bobbin 52 is set at the position of the cutter 62 shown in FIG. Further, the tag 1A or the long tag 1A 'is stacked and stored in the cartridge 40 of the tag transport mechanism 4A. In the state of the binding machine 100, the tip of the binding tool 13 wound around the bobbin 52 is set at the position of the cutter 62 shown in FIG. The tag 1A is stacked and stored in the cartridge 40 of the tag transport mechanism 4A, and the operation unit 106 is switched to the tag 1A.

  With these as the bundling processing conditions, in step ST1 shown in FIG. 33, the CPU 114 waits for “bundling start” to turn on the main switch 120 of the bundling machine 100. At this time, the user operates a start button (not shown) or the like with the operation unit 106 to instruct “binding start”. In response to this, the operation unit 106 outputs information indicating the operation data D <b> 1 = “binding start” to the CPU 114. The CPU 114 turns on the main switch 120 based on the operation data D1.

  As a result, the drive voltage is first supplied from the power supply circuit 20 to the motor drive unit 141b via the main switch 120. At this time, since the bag sensor switch 121 is OFF, the driving voltage is not supplied to the motor driving unit 150i, the motor driving unit 170c, and the motor driving unit 93. When the above-described CPU 114 obtains “binding start”, it reads out the control program stored in the EEPROM 113 of the control unit 110 shown in FIG. In order to execute control based on the bundling processing program, the process proceeds to step ST2.

  In step ST2, the CPU 114 determines whether the tag 1A (or long tag 1A ') is being conveyed. For example, when the CPU 114 inputs the transport data D8 indicating that the tag 1A is not transported from the tag sensor 109 illustrated in FIG. 10B, the CPU 114 proceeds to step ST3. On the other hand, when the CPU 114 receives the conveyance data D8 indicating that the tag 1A is being conveyed from the tag sensor 109, the CPU 114 proceeds to step ST4.

  In step ST3, the CPU 114 controls to carry the tag 1A. For example, the CPU 114 controls the tag feed roller 41a to rotate so that the lowermost tag 1A housed in the cartridge 40 is sent out one sheet. At this time, according to the conveyance example shown in FIG. 37, the tag 1A is held by the tag hooking claws 30b and 30b of the curl guide 30 in the standby state of the tag hold mechanism 3A and the guide plate mechanism 8A. Since the sensor flag protrusion 95f does not cross the slit of the guide plate sensor 107, the position detection data D6 of “H” level is output to the control unit 110.

  And it transfers to step ST4 and CPU114 determines whether the bag 14 was arrange | positioned in the binding port 103 of the binding machine 100. FIG. For example, the user inserts (places) the bag 14 into the binding port 103 shown in FIG. In this example, the bag 14 is inserted into the mounting space 92 b while pushing the guide plate 95. At this time, the user inserts the bag 14 so as to push the triangular space area of the binding port 103 separately.

  For example, in the binding port 103, when the bag 14 is inserted toward the triangular apex at the initial stage, the guide plate 95 is pushed in the direction in which the bag 14 is retracted. According to the intermediate stage of the mounting operation of the bag 14 shown in FIG. 36, when the guide plate 95 and the arm 121 'are almost pushed by the bag 14, the bag 14 is inserted into the mounting space 92b. After that, when the bag 14 is completely pushed into the mounting space 92b, the guide plate 95 operates so as to pop out again. This jumping out is performed by the biasing force of the spring.

  Thereby, the arm 121 ′ shown in FIG. 35 is rotated, and one end of the arm 121 ′ is detected by the bag sensor 108. The bag sensor 108 outputs information indicating the bag detection data D7 = “bag present” to the CPU 114. The CPU 114 turns on the bag sensor switch 121 based on the bag detection data D7 = “with bag” (double power supply countermeasure).

  That is, when the bag detection data D7 is input from the bag sensor 108, the CPU 114 turns on the bag sensor switch 121 and proceeds to step ST5. If the bag detection data D7 is not input from the bag sensor 108, the CPU 114 repeats the determination as to whether or not the bag 14 has been placed again.

  In step ST5, the CPU 114 determines whether or not the guide plate 95 is in a fixed position. In the above example, when the bag 14 is arranged at the binding port 103 by the user, the guide plate 95 in the arrangement process shown in FIG. 35 is once pushed and slid by the bag 14 as shown in FIG. . At this time, the CPU 114 determines whether or not the guide plate 95 once pushed returns to the original position. For example, the CPU 114 outputs from the guide plate sensor 107 when the sensor flag protruding portion 95f at the rear end of the guide plate 95 passes through the slit of the transmissive guide plate sensor 107 (see FIG. 22.23A). Whether or not the guide plate 95 has returned to the original position is determined based on the low level or high level position detection data D6.

  Further, the guide plate sensor 107 detects the guide plate 95 that has been slid and outputs position detection data D6 indicating that the bag 14 has been attached to the CPU 114. In this example, when the slit of the guide plate sensor 107 is shielded from light by the projecting portion 95f, the CPU 114 inputs “L” level position detection data D6. Further, when the guide plate sensor 107 is not shielded from light, the CPU 114 inputs “H” level position detection data D6.

  Therefore, when the guide plate 95 is not returned to the original position, that is, when the bag 14 is protruded from the guide plate 95 and the guide plate 95 is pressed, the guide plate sensor 107 is shielded from light. The position detection data D6 of “L” level is output.

  As described above, if the “H” level position detection data D6 is not output from the guide plate sensor 107 after inputting the “L” level position detection data D6, the bag 14 protrudes from the guide plate 95. The control is stopped without proceeding to the operation of the next step. At this time, for example, if the position detection data D6 of “H” level is not output from the guide plate sensor 107 even after 7 to 10 seconds have elapsed, the CPU 114 may warn with a beep sound or the like. When the CPU 114 inputs the “H” level position detection data D6, that is, when it is confirmed (recognized) that the guide plate 95 has returned to the original position, the process proceeds to step ST6.

  In step ST <b> 6, the CPU 114 determines whether the normal tag 1 </ b> A or the long tag 1 </ b> A ′ is set by the operation unit 106. For example, when the operation data D1 indicating the normal tag 1A is input from the operation unit 106, the CPU 114 proceeds to step ST7.

  In step ST7, the CPU 114 moves the curl guide 30 shown in FIG. For example, the CPU 114 rotates the moving motor 93 to slide the operation plate 32 shown in FIG. 7 in the direction of the arrow Q2 to move the curl guide 30 from the home position HP to the binding position P1, and the process proceeds to step ST8. .

  At this time, according to the conveyance example shown in FIG. 39, the tag holder drive mechanism 9A further moves the curl guide 30 from the position shown in FIG. 38, and the guide plate 95 is moved by the tag hooking claws 30b and 30b. It is made to push. With this later movement, the rear end portion of the protruding portion 95g of the guide plate 95 is in contact with the front end portion of the rail member 92h while the front end portion of the curl guide 30 is in contact with the front end portion of the guide plate 95. . At this time, the conveyance to the mounting space 92b of the tag 1A is completed.

  In step ST8, the CPU 114 conveys the binding tool 13. For example, the CPU 114 rotates the binding tool feed motor 50 i, pulls the binding tool 13 from the bobbin 52, and sends it to the tie slope 63. At this time, according to the conveyance example shown in FIG. 40, the tag holder drive mechanism 9A moves the curl guide 30 shown in FIG. 37 from the standby state in the previous period, and the leading end of the curl guide 30 interposes the tag 1A. It will be in the state contact | abutted to the front-end | tip part of the guide plate 95. FIG. That is, the tag 1A is sandwiched between the guide plate 95 and the curl guide 30, and the tag 1A can be prevented from falling off. Thereafter, in this state, the tag 1A is moved to the mounting space 92b. The guide plate sensor 107 outputs position detection data D6 of “L” level because the projecting portion 95f crosses. Thereafter, the process proceeds to step ST9.

  In step ST9, the CPU 114 controls the cutting tool 13 to be cut and the front end portion and rear end portion of the binding tool 13 'after cutting to face each other. For example, the CPU 114 rotates the moving motor 93 again to further slide the operation plate 32 shown in FIG. 9 in the direction of the arrow Q2, and is linked by the roller arm 101 attached to the lower end portion of the operation plate 32. The roller 97 is pushed to drive the cutter 62 and the approach arms 61a and 61b to which the link roller 97 is coupled to cut the binding tool 13 and the front end portion and rear end of the binding tool 13 ′ of the binding tool 13 cut. Bring the edges so that they face each other.

  At this point, the sensor flag protrusion 95f shields light across the slit of the guide plate sensor 107, and therefore outputs the “L” level position detection data D6 to the controller 110. Thereafter, the control unit 110 uses the position detection data D6 as a trigger to drive the tag holder driving mechanism 9A, the binding tool forming mechanism 6A forms the binding tool 13, and the binding tool fastening mechanism 7A of the binding tool fastening mechanism 7A cuts the tag 1A. It is bound by the subsequent binding tool 13 '. Then, the process proceeds to step ST13 shown in FIG.

  In step ST <b> 13, the CPU 114 controls to twist the binding tool 13 ′ after cutting. For example, the CPU 114 rotates the torsion motor 70c, rotates the torsion arm 70 shown in FIG. 7, and twists the binding tool 13 ′ after cutting in which the front end portion and the rear end portion are held on the torsion arm 70. . The guide plate 95 is locked by the cam plate 99 attached to the torsion arm 70 shown in FIG. This is because if the guide plate 95 is returned, the tag 1A is pushed, and it becomes difficult for the tag 1A to be deformed and the bundled object to come off.

  Regarding the lock function, according to the conveyance example shown in FIG. 40, the bundling process is completed, and the control unit 110 operates the lock mechanism 81. In the lock mechanism 81, the half-moon shaped cam plate 99 provided on the torsion arm 70 of the binder fastening mechanism 7A stops at a position rotated 180 ° from the standby state. By this rotation, the cam plate 99 stops at a position where it is caught by a cam engaging opening 95d provided in the guide plate 95. That is, the half-moon-shaped part of the cam plate 99 is stopped in a posture that forms an upper chord shape with respect to the opening 95d, and the cam plate 99 is caught by the opening 95d to lock the urging force toward the front side of the guide plate 95. Since the guide plate sensor 107 remains shielded from light by the protruding portion 95f, it outputs “L” level position detection data D6. This “L” level position detection data D6 indicates that the guide plate 95 is locked. Subsequently, the process proceeds to step ST14.

  In step ST14, the CPU 114 controls the curl guide 30, the left and right approach arms 61a and 61b, and the cutter 62 to return to their original positions. At this time, according to the conveyance example shown in FIG. 41, the control unit 110 controls the tag holder drive mechanism 9A to be driven to return the curl guide 30 to the standby position while the lock mechanism 81 is operated. For example, the CPU 114 rotates the shift motor 93 in the reverse direction and slides the operating plate 32 shown in FIG. 7 in the direction of the arrow Q3 opposite to the arrow Q2, thereby moving the curl guide 30 from the binding position P1 to the home position. Return to HP.

  At this time, the contact between the roller arm 101 attached to the lower end portion of the operating plate 32 and the link roller 97 is released. A tension spring 122 stretched between the link roller 97 and the locking shaft 97 ′ constantly urges the link roller 97 toward the locking shaft 97 ′. The roller arm shown in FIG. When the contact between 101 and the link roller 97 is released, the link roller 97 moves in the direction of the arrow Q3. The link roller 97 is pushed back through the cutter link 62c coupled to the cutter 62. The link roller 97 moves in the direction of the arrow Q3.

  As a result, the cutter 62 linked to the link roller 97 is retracted from the tip end portion of the tie slope 63 of the binder transport mechanism 5A. In this example, even if the curl guide 30 is retracted to the standby position, the guide plate 95 can be restored while the urging force of the spring springs 82a and 82b is overcome and the half-moon shaped portion of the cam plate 99 is caught by the opening 95d. It is in a state of being suppressed.

  Note that the guide plate 95 does not pop out because the guide plate 95 is locked by the cam plate 99 even after the curl guide 30 is retracted. Thus, the bundled bag 14 can be easily taken out with the guide plate 95 locked. Since the guide plate sensor 107 remains shielded from light by the projecting portion 95f, the position detection data D6 of “L” level is output (the lock mechanism remains active). Simultaneously with the above-described retreating process of the cutter 62, the left and right approach arms 61a and 61b engaged with the link roller 97 are returned to their original positions, and again constitute part of the binding tool guide paths 601 and 602, and step ST15. Migrate to

  In step ST15, the CPU 114 determines whether or not the bag 14 has been removed. At this time, the bag sensor 108 has returned to its original position by reversely rotating the arm 121 ′ rotated forward by the bag 14 being pressed in step ST4 described above when the bag 14 is removed. Detect whether or not.

  For example, when the bag 14 cannot be removed from the binding port 103 and the CPU 114 inputs bag detection data D7 indicating that the arm 121 ′ has not returned to the original position from the bag sensor 108, the bag 14 It is determined again whether or not has been extracted. When the bag 14 is extracted from the binding port 103 and the CPU 114 inputs bag detection data D7 indicating that the arm 121 ′ has returned to the original position from the bag sensor 108, the bag sensor switch 121 Is turned off, and the process proceeds to step ST16.

  In step ST16, the CPU 114 performs control so that the guide plate 95 locked in step ST13 is unlocked. For example, the CPU 114 causes the torsion motor 70c to make a half turn, causes the torsion arm 70 shown in FIG. 25 to make a half turn, and releases the guide plate 95 locked by the cam plate 99 attached to the torsion arm 70. Move on to ST17.

  In step ST <b> 17, the CPU 114 controls to load (carry) the tag 1 </ b> A into the curl guide 30. For example, the CPU 114 controls the tag feed roller 41a to rotate so that the lowermost tag 1A housed in the cartridge 40 is sent out one sheet. This tag loading process is for preparing in advance for the next bundling process. 37, the tag 1A is held by the tag hooking claws 30b and 30b of the curl guide 30 in the standby state of the tag hold mechanism 3A and the guide plate mechanism 8A. Since the sensor flag protrusion 95f does not cross the slit of the guide plate sensor 107, the position detection data D6 of “H” level is output to the control unit 110. Then, the process proceeds to step ST18.

  In step ST <b> 18, when the information for turning off the main switch 120, that is, the information indicating the operation data D <b> 1 = “end of binding” is input from the operation unit 106, the CPU 114 is based on the operation data D <b> 1 = “end of binding”. The main switch 120 is turned off. If the main switch is not turned off, the process returns to step ST2 to repeat the above-described processing. When the main switch 120 is off, the bundling process ends. In addition, the control part 110 transfers to a sleeping state. The sleeping state is a state in which no driving voltage is supplied from the power supply circuit 20 to the motor driving unit 141b, the motor driving unit 150i, the motor driving unit 170c, and the motor driving unit 93. The function and the memory function are working, and the other functions are in a paused state (power saving mode).

  In step ST6, when the CPU 114 inputs operation data D1 indicating another tag (hereinafter referred to as long tag 1A ') from the operation unit 106, the process proceeds to step ST10. In step ST10, the CPU 114 moves the curl guide 30 and sends out the long tag 1A '. For example, the CPU 114 rotates the moving motor 93 to slide the operation plate 32 shown in FIG. 7 in the direction of the arrow Q2 to move the curl guide 30 from the home position HP to the binding position P1. At this time, the CPU 114 rotates the tag feed roller 41a shown in FIG. 10 simultaneously with the advancement of the curl guide 30, and feeds the rear end portion of the information presentation unit 10C of the long tag 1A ′ remaining in the cartridge 40. Thus, the process proceeds to step ST11.

  In step ST11, the CPU 114 transports the binding tool 13. For example, the CPU 114 rotates the binding tool feed motor 50i, pulls the binding tool 13 from the bobbin 52, sends it to the tie slope 63, and proceeds to step ST12.

  In step ST12, the CPU 114 controls the cutting tool 13 so that the leading end and the rear end of the binding tool 13 ′ cut from the binding tool 13 face each other and the tag 1A is further sent out. . For example, the CPU 114 again rotates the moving motor 93 to further slide the operation plate 32 shown in FIG. 7 in the direction of the arrow Q2, and the roller arm 101 attached to the lower end portion of the operation plate 32. By pushing the link roller 97, the cutter 62 and the left and right approach arms 61a and 61b of the link roller 97 are driven to cut the binding tool 13 and the binding tool 13 'of the binding tool 13 cut. The front end and the rear end are controlled so as to face each other.

  At this time, the CPU 114 further slides the operating plate 32 in the direction of the arrow Q2 and simultaneously rotates the tag feed roller 41a again to rear end the information presentation unit 10C of the long tag 1A ′ remaining in the cartridge 40. The part is completely sent out, and the process proceeds to the above-described step ST13 to twist and bind the binding tool 13 ′ after cutting. Step ST13 and subsequent steps are as described above (see steps ST13 to ST18).

  Thus, according to the binding machine 100 as the first embodiment, the band-shaped cut binding tool 13 ′ is pleated from the bag 14 using the two locking holes 11 m and 11 m provided in the tag 1 A. When the tag 1A is wound around a fold and attached to the fold fold of the bag 14, a tag support member 30e is provided at the upper end of the curl guide 30 and functions to be hooked on the upper portion of the tag.

  Therefore, the tag 1A can be prevented from rotating around the tag hooking claws 30b and 30b. As a result, it is possible to prevent the tag from falling off due to the rotation of the tag as compared with the case where the tag support member 30e is not attached. Further, the binding tool 13 inserted from the locking hole 11m of one tag 1A can be pulled out from the other locking hole 11m with good reproducibility. Moreover, the tag 1A can be smoothly pulled out from the tag transport mechanism 4A after binding, and a highly reliable binding machine 100 can be provided.

  Further, according to the binding machine 100, the tag transport mechanism 4A includes the tag support member 42c, and when the tag 1A is delivered from the tag transport mechanism 4A to the tag hold mechanism 3A, the tag support member 42c releases the rear end of the tag 1A. Will be able to delay.

  Accordingly, as shown in FIG. 19, even when handling a tag 1A that is shorter than a normal length, etc., it is possible to prevent a drop due to a tag delivery error as compared with the case where the tag support member 42c is not attached. As a result, the tag 1A can be transferred from the tag transport mechanism 4A to the tag holder mechanism 3A with good reproducibility regardless of whether the tag 1A is long or short, and a highly reliable binding machine 100 can be provided. It was. As a result, the tag 1A can be transported from the tag holder mechanism 3A to the binding tool fastening mechanism 7A with good reproducibility.

  Further, according to the binding machine 100, the band-shaped cut binding tool 13 'is wound around the fold fold of the bag 14 using the two locking holes 11m, 11m provided in the tag 1A, and the tag 1A is When attached to the fold fold of the bag 14, a movable guide plate mechanism 8A having a notch 95b is provided, and the tag 1A is held by the tag hold mechanism 3A and the guide plate 95, and the mounting space 92b The tag 1 </ b> A can be transported to the fold opening of the inserted bag 14.

  Therefore, it is possible to prevent the tag 1A from dropping off during the tag conveyance. Moreover, since the notch portion 95b for guiding the bag fold fold extends from the mounting space portion 92b to the outside, the fold fold opening of the bag 14 is inserted into the mounting space portion 92b accurately before carrying the tag. become able to. As a result, a highly reliable tag attaching device or the like can be provided.

  In addition, according to the step passage structure 60 of the binding machine 100, the binding tool guide paths 601 and 602 and the binding tool path 303 are set high on the upstream side and low on the downstream side in the direction in which the binding tool 13 enters. In the above-described example, all the steps ε1, ε2, ε3, ε4, and ε5 are set lower on the downstream side than on the upstream side.

  Accordingly, the band-shaped cut binder 13 'is wound around the fold fold of the bag 14 using the two locking holes 11m, 11m provided in the tag 1A, and the tag 1A is wrapped around the fold fold of the bag 14. When attaching, the situation where the tip of the binding tool 13 hits the tip of the binding tool guide paths 601 and 602 can be avoided, so the binding tool forming mechanism 6A can be provided without providing a guide structure such as chamfering on the binding tool guide paths 601 and 602. Thus, the binding tool 13 can be smoothly inserted from the binding tool guide path 601 into the binding tool path 303 of the curl guide 30. Further, the binder 13 can be smoothly inserted from the binder passage 303 into the binder guide path 602 of the binder forming mechanism 6A. Thereby, the feeding failure of the binding tool 13 can be prevented.

  FIG. 42 is a partially enlarged perspective view showing a configuration example of the tag spring support mechanism 2A ′ of the binding machine 200 as the second embodiment.

  The binding machine 100 shown in FIG. 42 is provided with a tag spring support mechanism 2A ′. The tag spring support mechanism 2A ′ includes a pair of torsion spring members 21 and 22 constituting an example of a pressing member, and a binding tool forming mechanism 6A adjacent to the binding tool fastening mechanism 7A from the tag transport mechanism 4A via the tag hold mechanism 3A. It operates so as to press down the side end portion of the tag 1 </ b> A conveyed from the both sides.

  In this example, a tag support member 30e provided at a predetermined portion from the upper part of the tag holder mechanism 3A to the binding device passage 303 holds the upper end of the tag 1A, and the torsion spring members 21 and 22 hold the side end of the tag 1A. It is made to hold down from both sides. As the torsion spring members 21 and 22, a member obtained by twisting a spring member such as a SUS wire, a steel wire, a high carbon steel wire, or a piano wire into a coil shape is used.

  For example, the torsion spring member 21 is attached on the intermediate chassis portion 92 a in front of the operation plate 32. The torsion spring member 21 includes a hollow spiral coil portion 21a and two spring leg portions (hereinafter referred to as a movable leg portion 21b and a fixed leg portion) extending in different directions from the spiral coil portion 21a at a predetermined opening angle. 21c).

  The spiral coil portion 21a is pivotally supported by the intermediate chassis 92a. For example, it is rotatably supported by a shaft portion 911 standing on the intermediate chassis portion 92a. One of the movable legs 21b is curled in a circular shape at the tip to soften the contact with the tag 1A, and is brought into contact with a position that holds one end of the tag 1A. The other fixed leg 21c is fixed to a forming mechanism mounting substrate 92i on the intermediate chassis 92a. For example, the end portion of the substrate 92 i is bent to form a protruding portion 912, and is fixed inside the protruding portion 912.

  Further, the torsion spring member 22 is attached to the intermediate chassis portion 92a on the tag transport mechanism 4A sandwiching the tag hold mechanism 3A. The torsion spring member 22 also includes a hollow spiral coil portion 22a and two spring leg portions (hereinafter referred to as a movable leg portion 22b and a fixed leg portion) extending in different directions from the spiral coil portion 22a at a predetermined opening angle. 22c).

  The spiral coil portion 22a is pivotally supported by the intermediate chassis 92a on the tag transport mechanism 4A. For example, it is rotatably supported by a shaft portion 913 erected between two intermediate chassis portions 92a and 92a '. One of the movable legs 22b is curled in a circular shape at the tip to soften the contact with the tag 1A, and is brought into contact with a position that holds the other side end of the tag 1A. The other fixed leg portion 22c is fixed to an engagement pin 914 provided upright between the intermediate chassis portions 92a and 92a '. As the engaging pin 914, for example, a convex pin (dubbed) for holding a space provided between the two intermediate chassis portions 92a and 92a 'may be used. The fixed leg 22c may be fixed so as to be wound around the engagement pin 914, for example. Thereby, the tag spring support mechanism 2A 'is configured.

  Next, an example of the function of the tag spring support mechanism 2A ′ of the binding machine 200 will be described. 43 and 44 are top views showing functional examples (parts 1 and 2) of the tag spring support mechanism 2A '. FIG. 43A is a top view showing a standby example of the tag hold mechanism 3A during standby of the tag spring support mechanism 2A 'and before tag loading.

  According to the standby state of the tag spring support mechanism 2A ′ shown in FIG. 43A, the movable leg 21b of the torsion spring member 21 and the movable leg 22b of the torsion spring member 22 and the curved guide protrusion 30c of the curl guide 30 are interposed. A gap is provided so that the tag tip can be easily attached to the tag hooking claws 30b, 30b and the tag support member 30e when the tag is loaded. In the standby state of the tag holder mechanism 3A and the tag spring tag support mechanism 2A ′, the tag carrying mechanism 4A as shown in FIG. 16 is operated to pull out the tag 1A from the cartridge 40, and the tag hooking claws 30b, 30b of the curl guide 30 are drawn. (See FIG. 46).

  Here, when the angle formed by the movable leg 21b and the fixed leg 21c is the opening angle θ1, the opening angle θ1 is, for example, about θ1 = 90 °. When the angle formed by the movable leg portion 22b and the fixed leg portion 22c is the opening angle θ2, the opening angle θ2 is about θ2 = 230 °, for example. The postures of the torsion spring members 21 and 22 in the standby state are maintained at these opening angles θ1 and θ2.

  FIG. 43B is a top view showing an example of the deformation operation of the tag spring support mechanism 2A ′ after loading the tag. According to the tag spring tag support mechanism 2A ′ shown in FIG. 43B, when the tag holder driving mechanism 9A shown in FIG. 7 operates from the standby state shown in FIG. 43A, the tag holder mechanism 3A advances in the direction of the binding tool forming mechanism 6A. The tip of the curl guide 30 and the tip of the torsion spring members 21 and 22 come into contact with each other. At this time, the torsion spring members 21 and 22 still maintain the standby state.

  FIG. 44A is a top view showing a deformation operation example (previous deformation) of the tag spring support mechanism 2A ′ during tag conveyance. According to the modification operation example of the tag spring support mechanism 2A ′ shown in FIG. 44A, the tag holder drive as shown in FIG. 7 is performed from the contact state of the tip portion of the curl guide 30 shown in FIG. 43B with the tag spring support mechanism 2A ′. When the mechanism 9A further operates and the tag holder mechanism 3A further advances in the direction of the binding tool forming mechanism 6A, the distal end portion of the curl guide 30 overcomes the urging force of the torsion spring members 21 and 22, and the distal end portion is contacted. It approaches in the direction of the binding tool forming mechanism 6A while in contact.

  At this time, the opening angle θ1 of the torsion spring member 21 and the opening angle θ2 of the torsion spring member 22 change. In this example, the opening angle θ1 of the torsion spring member 21 pushed by the curl guide 30 changes from the initial θ1 = 90 ° to θ1 = 70 °, and similarly, the opening angle θ2 of the torsion spring member 22 is the initial value. Changes from θ2 = 230 ° to θ2 = 195 ° (previous deformation).

  By the movement of the tag holder mechanism 3A, the leading end portion of the curl guide 30 comes into contact with the leading end portions of the torsion spring members 21 and 22 via the tag 1A. That is, the tag 1A is sandwiched between the torsion spring members 21 and 22 and the curl guide 30, and the tag 1A can be prevented from falling off. Thereafter, in this state, the tag 1A is moved to the mounting space 92b (see FIGS. 47, 48, and 49).

  FIG. 44B is a top view showing a deformation operation example (late deformation) of the tag spring support mechanism 2A ′ during tag conveyance. According to the modified operation example of the tag spring support mechanism 2A ′ shown in FIG. 44B, the operation is further continued by the tag hold drive mechanism 9A as shown in FIG. 7, and the tag hold mechanism 3A moves forward to the binding tool forming mechanism 6A. It has been reached. In this state, the tag spring support mechanism 2A 'in contact with the tip of the curl guide 30 shown in FIG. 44A is deformed. At this time, the curl guide 30 stops at the front end of the binding tool forming mechanism 6A while the front end portion thereof overcomes the further urging force of the torsion spring members 21 and 22 and the front end portion is in contact therewith. At this time, the conveyance to the mounting space 92b of the tag 1A is completed (see FIG. 50).

  44A, the opening angle θ1 of the torsion spring member 21 at the time of arrival is further changed compared to the opening angle θ1 of the torsion spring member 21 shown in FIG. 44A. Similarly, the opening angle θ2 of the torsion spring member 22 at the time of arrival is further changed compared to the opening angle θ2 of the torsion spring member 22.

  In this example, the opening angle θ1 of the torsion spring member 21 pushed by the curl guide 30 changes from the initial θ1 = 90 ° to θ1 = 20 °. Similarly, the opening angle of the torsion spring member 22 θ2 changes from the initial θ2 = 230 ° to θ2 = 150 ° (late deformation).

  FIG. 45 is a flowchart illustrating an operation example of the binding machine 200. 46 to 50 are partially enlarged perspective views supplementing an operation example of the tag spring support mechanism 2A 'during tag conveyance.

  In this example, the binding machine 200 includes a control unit 110 as shown in FIG. 32, and the CPU 114 of the control unit 110 uses a tag hold mechanism 3A, a tag transport mechanism 4A, a binding tool transport mechanism 5A, and a binding tool forming mechanism. An example will be described in which 6A, the binder fastening mechanism 7A, and the tag holder drive mechanism 9A are controlled.

  First, in step ST21, the CPU 114 detects whether the bag 14 is inserted. At this time, it is detected that the bag 14 has been inserted by turning on the main switch 120 (see step ST1 in FIG. 33).

  Next, in step ST22, the CPU 114 controls the tag transport mechanism 4A so that the tag 1A is pulled out from the cartridge 40 and loaded into the curl guide 30. In the standby state of the tag spring tag support mechanism 2 </ b> A ′ and the tag hold mechanism 3 </ b> A, the tag transport mechanism 4 </ b> A is operated to pull out the tag 1 </ b> A from the cartridge 40 and hold it by the tag hooking claws 30 b and 30 b of the curl guide 30. In this example, in the tag spring support mechanism 2A ′ shown in FIG. 46, in the gap between the movable leg portion 21b of the torsion spring member 21 and the movable leg portion 22b of the torsion spring member 22, and the curved guide protrusion 30c of the curl guide 30, Tag 1A is loaded. The tip of the tag is taken into the inner portion of the tag support member 30e, and the mounting portion 11A is caught by the tag hooking claws 30b and 30b.

  In step ST23, the CPU 114 controls the tag hold driving mechanism 9A so as to convey the tag hold mechanism 3A holding the tag 1A to the binding tool forming mechanism 6A. At this time, according to the tag spring support mechanism 2A ′ shown in FIG. 47, the tag holder mechanism 3A holding the tag 1A shown in FIG. 46 with the curl guide 30 and the torsion spring members 21 and 22 The portion comes into contact with the tip portions of the torsion spring members 21 and 22 with the tag 1A interposed therebetween. That is, the tag 1A is sandwiched between the torsion spring members 21 and 22 and the curl guide 30, and the tag 1A can be prevented from falling off.

  Further, according to the tag spring support mechanism 2A ′ shown in FIG. 48, the tag hold mechanism 3A in which the tag 1A shown in FIG. 47 is held by the curl guide 30 and the torsion spring members 21 and 22 is as shown in FIG. The tag holder drive mechanism 9A further operates and further advances in the direction of the binding tool forming mechanism 6A (see FIG. 49). According to the tag spring support mechanism 2A ′ shown in FIG. 49, the curl guide 30 has its tip end overcomes the urging force of the torsion spring members 21 and 22, and the curb guide 30 remains in contact with the tip end of the binding tool forming mechanism 6A. Approach the direction.

  Then, according to the tag spring support mechanism 2A ′ shown in FIG. 50, the tag spring support mechanism 2A ′ in contact with the tip of the curl guide 30 shown in FIG. 48 is further operated by the tag hold drive mechanism 9A. In this state, the tag holder mechanism 3A moves forward and reaches the binding tool forming mechanism 6A. At this time, the distal end portion of the curl guide 30 overcomes the further urging force of the torsion spring members 21 and 22, and stops in front of the binding tool forming mechanism 6A while keeping the distal end portion in contact therewith. At this time, the conveyance to the mounting space 92b of the tag 1A is completed.

  Thereafter, in step ST24, the CPU 114 controls the binder transport mechanism 5A so that the binder 13 is pulled out from the bobbin 52 and inserted into the tags 1A and 11m and the binder passage 303 of the curl guide 30 (step in FIG. 33). (Refer to ST8).

  Next, in step ST25, the CPU 114 controls the binding tool forming mechanism 6A so as to cut and form the binding tool 13 (see step ST9 in FIG. 33).

  In step ST26, the CPU 114 controls the binding tool fastening mechanism 7A so as to fasten the cut binding tool 13 'inserted through the tag 1A to the fold opening of the bag 14 (see step ST13 in FIG. 34).

  Thereafter, in step ST27, the CPU 114 detects whether the bag 14 is discharged. At this time, it is detected that the bag 14 has been discharged by turning off the main switch (see step ST15 in FIG. 34).

  In step ST28, the CPU 114 determines the end. For example, the CPU 114 detects off information of the main switch 120. When the off information of the main switch 120 is detected, the binding control is terminated. When the power-off information is not detected, the CPU 114 returns to step ST21, and the CPU 114 repeats the above-described processing, so that the tag hold mechanism 3A, the tag transport mechanism 4A, the binding tool transport mechanism 5A, the binding tool forming mechanism 6A, and the binding tool fastening mechanism. 7A and the tag holder drive mechanism 9A are controlled.

  Thus, according to the binding machine 200 as the second embodiment, the band-shaped cut binding tool 13 ′ is pleated on the bag 14 using the two locking holes 11 m and 11 m provided in the tag 1 A. When the tag 1A is wound around the fold and attached to the fold fold of the bag 14, when the tag 1A is delivered from the tag transport mechanism 4A to the binding tool forming mechanism 6A via the tag hold mechanism 3A, the tag transport mechanism 4A The side end of the tag 1 </ b> A conveyed to the binding tool forming mechanism 6 </ b> A is pressed from both sides by a pair of torsion spring members 21 and 22 provided in the main body chassis portion 92.

  Accordingly, when the tag 1A is delivered from the tag transport mechanism 4A to the binding tool forming mechanism 6A via the tag hold mechanism 3A, the tag support member 30e that supports the tip of the tag 1A can be assisted. As a result, when handling a tag 1A that is shorter than the normal length, etc., it is possible to prevent the tag from falling off due to a mistake in tag delivery compared to the case where the torsion spring members 21 and 22 are not attached. Therefore, regardless of whether the tag 1A is long or short, the tag 1A can be transferred from the tag transport mechanism 4A to the binding tool forming mechanism 6A with good reproducibility, and a highly reliable binding machine 200 can be provided. became.

  In addition, although the case where the twist tie which provided strip | belt-shaped coating | cover was used for the core wire member like a wire was demonstrated about the binding tool 13, it does not restrict to this but the covered wire which a cross section forms a substantially circular shape is used as the binding tool 13. The present invention can be applied even when used. Further, it goes without saying that the present invention can be applied even when a wire without a coating, a coated wire having a resin core wire, a linear member made of resin, a belt-like member, or the like is used as the binding tool 13. Nor.

  The present invention is applied to a binding machine that is attached to a bag containing confectionery and vegetables and binds tags that describe information such as advertising texts, producer information, and cooking recipes with a binding tool. It can also be applied to a binding machine that is attached to bundled wires and binds tags that describe wiring information etc. with a binding tool, and further binds identification tags in the agricultural field such as seedling cultivation with a binding tool. It is also applicable to the machine.
