Move to slide.

  1 and 2 sends the driving force of the intermittent drive gear 56 attached to the shaft 35 of the first working plate drive gear 34 shown in FIG. It is transmitted to a gear 58 provided coaxially with the roller 50.

  FIG. 19 is a perspective view showing an example of the configuration and operation of the intermittent drive gear and the timing gear.

  The intermittent drive gear 56 includes a gear portion 56a in which a gear is formed on a part of the circumference, and a rotation restricting portion 56b that restricts the rotation of the timing gear 57 within a range where the gear portion 56a is not formed. Thus, the gear portion 56a meshes with the timing gear 57 at a predetermined timing. The rotation restricting portion 56b is configured by an arc-shaped disc having a larger diameter than the gear portion 56a, and rotates integrally with the gear portion 56a.

  The tooth thickness of the timing gear 57 is configured to be thicker than the gear portion 56a of the intermittent drive gear 56. The timing gear 57 is engaged with the gear portion 56a of the intermittent drive gear 56 in the thickness direction. Is done.

  On the other hand, the position of the timing gear 57 facing the locus of the rotation restricting portion 56b due to the rotation of the intermittent drive gear 56 in the thickness direction is the locus of the rotation restricting portion 56b as shown in FIG. Accordingly, a rotation restricting recess 57a is formed by cutting out in an arc shape.

  Accordingly, as shown in FIG. 19B, when the rotation restricting portion 56 b of the intermittent drive gear 56 is in the rotation restricting recess 57 a of the timing gear 57, the rotation restricting portion 56 b and the rotation restricting recess 57 a are connected to the timing gear 57. Therefore, the rotation of the timing gear 57 is restricted. On the other hand, the intermittent drive gear 56 rotates freely because the rotation restricting recess 57a has a shape along the locus of the rotation restricting portion 56b.

  The rotation restricting portion 56b enters the rotation restricting recess 57a, the intermittent drive gear 56 rotates in a state where the rotation of the timing gear 57 is restricted, and the gear portion 56a meshes with the timing gear 57 as shown in FIG. Then, the rotation restricting portion 56b is disengaged from the rotation restricting recess 57a. Thereby, the timing gear 57 is rotated by the rotation of the intermittent drive gear 56.

  Further, when the intermittent drive gear 56 and the timing gear 57 rotate and the gear portion 56a is disengaged from the timing gear 57, the rotation restricting portion 56b enters the rotation restricting recess 57a, and the rotation of the timing gear 57 is restricted.

  Thereby, the timing gear 57 rotates only during a predetermined timing while the intermittent drive gear 56 makes one rotation, and the feed roller 50 is driven to rotate. Further, while the rotation of the timing gear 57 is stopped, the rotation restricting portion 56 b of the intermittent drive gear 56 enters the rotation restricting recess 57 a of the timing gear 57 to restrict the rotation of the timing gear 57. Thereby, the timing at which the gear portion 56a of the intermittent drive gear 56 and the timing gear 57 are engaged with each other is adjusted so that malfunction such as gear engagement does not occur.

  In the binding tool fastening mechanism 7A, the driving force of the intermittent drive gear 71 attached to the shaft 67 of the second operation plate drive gear 65 shown in FIG. 17 is transmitted to the torsion arm 70 via the timing gear 72 and the bevel gear 73. The

  The intermittent drive gear 71 includes a gear portion 71a in which a gear is formed on a part of the circumference, and a rotation restricting portion 71b that restricts the rotation of the timing gear 72 within a range where the gear portion 71a is not formed. Thus, the gear portion 71a meshes with the small gear 72a of the timing gear 72 at a predetermined timing. The rotation restricting portion 71b is formed of an arc-shaped disc having a larger diameter than the gear portion 71a, and rotates integrally with the gear portion 71a.

  The tooth thickness of the small gear 72a of the timing gear 72 is configured to be thicker than the gear portion 71a of the intermittent drive gear 71, and the position where the small gear 72a of the timing gear 72 meshes with the gear portion 71a of the intermittent drive gear 71 in the thickness direction is A gear is formed on the entire circumference.

  On the other hand, the position of the small gear 72a of the timing gear 72 facing the locus of the rotation restricting portion 71b due to the rotation of the intermittent drive gear 71 in the thickness direction matches the locus of the rotation restricting portion 71b as shown in FIG. As shown in a), the rotation restricting recess 72b is formed by cutting out into an arc shape.

  Thus, as shown in FIG. 19B, when the rotation restricting portion 71b of the intermittent drive gear 71 is in the rotation restricting recess 72b of the small gear 72a of the timing gear 72, the rotation restricting portion 71b and the rotation restricting recess Since 72b has an arc shape opposite to the rotation direction of the timing gear 72, the rotation of the timing gear 72 is restricted. On the other hand, the intermittent drive gear 71 rotates freely because the rotation restricting recess 72b has a shape along the locus of the rotation restricting portion 71b.

  The rotation restricting portion 71b enters the rotation restricting recess 72b, and the intermittent drive gear 71 rotates in a state where the rotation of the timing gear 72 is restricted. As shown in FIG. When engaged with the gear 72a, the rotation restricting portion 71b is disengaged from the rotation restricting recess 72b. Thereby, the timing gear 72 is rotated by the rotation of the intermittent drive gear 71.

  Further, when the intermittent drive gear 71 and the timing gear 72 rotate and the gear portion 71a is disengaged from the small gear 72a of the timing gear 72, the rotation restricting portion 71b enters the rotation restricting recess 72b, and the rotation of the timing gear 72 is restricted. The

  As a result, the timing gear 72 rotates only during a predetermined timing during which the intermittent drive gear 71 rotates once, and the torsion arm 70 is rotationally driven. Further, while the rotation of the timing gear 72 is stopped, the rotation restricting portion 71b of the intermittent drive gear 71 enters the rotation restricting recess 72b of the small gear 72a of the timing gear 72, thereby restricting the rotation of the timing gear 72. ing. Thereby, the timing at which the gear portion 71a of the intermittent drive gear 71 and the small gear 72a of the timing gear 72 are engaged with each other is adjusted so that malfunction such as gear engagement does not occur.

  The bevel gear 73 includes a first bevel gear 73b having a flat gear 73a that meshes with the large gear 72c of the timing gear 72, and a second bevel gear 73c that is attached to the shaft of the torsion arm 70 and meshes with the first bevel gear 73b. The axial direction of the intermittent drive gear 71 is converted by 90 degrees and the driving force is transmitted to the torsion arm 70.

  As described above, the intermittent drive gear 56 that drives the binder transport mechanism 5A is disposed coaxially with the first operating plate drive gear 34 that drives the tag holder mechanism 3A, and intermittent drive that drives the binder fastener mechanism 7A. The gear 71 is arranged coaxially with the second operation plate drive gear 65 that drives the binding tool forming mechanism 6A.

  As a result, the holding and releasing operation of the tag 1A by the curl guide 30 with the driving force of a single motor (not shown), the conveying operation of the binding device 13 by the feed roller 50, and the cutting and molding of the binding device 13 by the abutment arm 60. The operation and the fastening operation of the binding tool 13 by the torsion arm 70 are interlocked at a predetermined timing.

<Example of operation of binding machine of this embodiment>
20 and 21 are operation explanatory views of the operation plate. Next, an operation example of attaching the tag 1A to the bag 14 by the binding machine 2A of the present embodiment will be described with reference to each drawing.

  First, the binding machine 2A is in the initial state shown in FIG. From this state, when it is detected by a sensor (not shown) that the bag 14 is set in the mounting space 31c, one tag 1A is conveyed to the curl guide 30 of the tag holder mechanism 3A by the tag conveying mechanism 4A shown in FIG. The

  As shown in FIG. 14A, the tag 1 </ b> A conveyed to the curl guide 30 is held by the curl guide 30 after the recess 12 m is locked to the tag hooking claw portion 30 b.

  FIG. 22 is an operation explanatory view showing the binding machine 2 </ b> A in the process of forming the conveyance path of the binding tool 13.

  When a motor (not shown) of the binding machine 2A is driven to rotate, the first operating plate driving gear 34 and the second operating plate driving gear 65 shown in FIG. 17, the intermittent driving gear 56 and the intermittent driving gear 71 shown in FIG. Is driven to rotate.

  When the binding machine 2A is driven to rotate in the direction of arrow R1 from the initial state shown in FIG. 20 (a), the guide roller (not shown) of the first operating plate 32 is moved to the position shown in FIG. As shown in FIG. 20B, the first operating plate 32 slides from the origin position H1 in the direction of the arrow F1 by being guided by one operating portion 34d of the cam groove 34a. Thereby, as shown in FIG. 22, the curl guide 30 moves in the direction of the arrow F <b> 2 and is abutted against the abutment guide 31.

  When the curl guide 30 holding the tag 1 </ b> A is abutted against the abutment guide 31, the tag 1 </ b> A is sandwiched between the curl guide 30 and the abutment guide 31. Thereby, as shown in FIG. 14B, the tag 1 </ b> A has a shape in which the vicinity of the mounting portion 11 </ b> A is mainly curved in the lateral direction, following the shape of the tag bending protrusion 30 a. The tag 1A is aligned with the recess 12m locked to the tag hooking claw 30b of the curl guide 30, so that the position of the locking hole 11m is aligned with the binding tool passage 30c of the curl guide 30.

  Further, the curling guide 30 is abutted against the abutting guide 31, so that the binding tool passage 30c of the curling guide 30 and the guide groove 31b of the guide block 31a of the abutting guide 31 are connected through the locking hole 11m of the tag 1A. .

  As a result, the guide groove 31b of one abutting guide 31 passes through one locking hole 11m of the tag 1A, and the binding tool passage 30c of the curl guide 30 passes through the other locking hole 11m of the tag 1A, and the other guide. A path leading to the guide groove 31b of the contact guide 31 is formed.

  When the second actuating plate drive gear 65 is driven to rotate in the direction of the arrow R2 in order to rotate the first actuating plate drive gear 34 from the initial state shown in FIG. The guide roller (not shown) of the operation plate 64 is guided by the first operation stop portion 65b of the cam groove 65a as shown in FIG. 20B, so that the second operation plate 64 slides from the origin position H2. Do not move.

  Further, as shown in FIG. 19B, the intermittent drive gear 56 coaxial with the first operating plate drive gear 34 has the rotation restricting portion 56b entered into the rotation restricting recess 57a of the timing gear 57, and the timing gear 57. , And the gear portion 56a of the intermittent drive gear 56 does not mesh with the timing gear 57, so that the feed roller 50 is not rotationally driven and the binding tool 13 is not conveyed.

  Further, in the intermittent drive gear 71 coaxial with the second operation plate drive gear 65, the rotation restricting portion 71b enters the rotation restricting recess 72b of the small gear 72a of the timing gear 72, and the rotation of the timing gear 72 is restricted, Since the gear portion 71a of the intermittent drive gear 71 does not mesh with the small gear 72a of the timing gear 72, the torsion arm 70 is not rotationally driven.

  FIG. 23 is an operation explanatory view showing the binding machine 2 </ b> A in the step of transporting the binding tool 13.

  When the first operation plate drive gear 34 rotates to a position where the curl guide 30 abuts against the abutment guide 31, a guide roller (not shown) of the first operation plate 32 is shown in FIGS. 20 (b) to 20 (c). As described above, by being guided by the second operation stop portion 34c of the cam groove 34a, the sliding movement of the first operation plate 32 is stopped, and the curl guide 30 is held at a position where it abuts against the abutment guide 31. Is done.

  From this state, when the first working plate drive gear 34 is further rotated in the direction of the arrow R1, the gear portion 56a of the coaxial intermittent drive gear 56 is rotated as shown in FIG. 56b enters the rotation restricting recess 57a and meshes with the timing gear 57 whose rotation position is restricted, and the rotation restricting portion 56b is detached from the rotation restricting recess 57a.

  Accordingly, the timing gear 57 is rotated by the rotation of the intermittent drive gear 56, the feed roller 50 is rotated in the direction of the arrow W1, and the binding tool 13 is conveyed. When the binding tool 13 is transported, the curling guide 30 forms a transport path for the binding tool 13 so that the binding tool 13 is passed through the two locking holes 11m of the tag 1A.

  In the process in which the feed roller 50 is driven to rotate, the second operating plate driving gear 65 is rotating, but the guide roller (not shown) of the second operating plate 64 is moved from FIG. As shown in c), the second operation plate 64 does not slide by being guided by the first operation stop portion 65b of the cam groove 65a. Further, since the intermittent drive gear 71 coaxial with the second operation plate drive gear 65 does not mesh with the small gear 72a of the timing gear 72, the torsion arm 70 is not rotationally driven.

  FIG. 24 is an operation explanatory view showing the binding machine 2A in the process of cutting the binding tool 13, and FIG. 25 is an operation explanatory view showing the binding machine 2A in the process of forming the binding tool 13.

  When the intermittent drive gear 56 is rotationally driven until the binding tool 13 is conveyed to a predetermined position, the gear portion 56a of the intermittent drive gear 56 is separated from the timing gear 57, and as shown in FIG. 19B, the rotation restricting portion 56b. Enters the rotation restricting recess 57a, the rotation of the timing gear 57 is restricted, and the conveyance of the binding tool 13 is stopped.

  When the second operating plate driving gear 65 is further rotated in the direction of the arrow R2 from the state where the gear portion 56a of the intermittent driving gear 56 is separated from the timing gear 57, a guide roller (not shown) of the second operating plate 64 is moved. As shown in FIGS. 20 (c) to 21 (a), the second operating plate 64 slides from the origin position H2 in the direction of arrow F3 by being guided by one operating portion 65d of the cam groove 65a. . As a result, the link center 64a to which the first link 61 is coupled slides together with the second operating plate 64, and the pair of close arms 60 are rotationally driven in the direction of the arrow W2 with the shaft 60a as a fulcrum, and are bound. The tool forming claw portion 60c is closed.

  In the operation of closing the shifting arm 60, first, as shown in FIGS. 15B and 24, the roller 62a is pushed by the cam surface 63a of the second link 63, and the conveying path of the binding tool 13 by the guide member 53 is changed. The cutter 62 moves against the spring 62b in the closing direction, and the binding tool 13 is cut at a predetermined position.

  As shown in FIG. 25, when the approach arm 60 is further closed, both ends of the tying member 13 cut to a predetermined length are formed into a shape that is brought close to the torsion arm 70.

  Now, in the step of rotating the moving arm 60, the first operating plate driving gear 34 is rotating, but the guide roller (not shown) of the first operating plate 32 is moved from FIG. As shown in a), by being guided by the second operation stop portion 34c of the cam groove 34a, the first operation plate 32 does not slide and the curl guide 30 is abutted against the abutment guide 31. Held in position. Further, since the gear portion 71a of the intermittent drive gear 71 coaxial with the second operation plate drive gear 65 does not mesh with the small gear 72a of the timing gear 72, the torsion arm 70 is not rotationally driven.

  FIG. 26 is an operation explanatory view showing the binding machine 2 </ b> A in the process of fastening the binding tool 13.

  When the second operation plate drive gear 65 rotates to a position where the pair of close arms 60 are closed, the guide roller (not shown) of the second operation plate 64 is moved as shown in FIGS. 21 (a) to 21 (b). By being guided by the second operation stop portion 65c of the cam groove 65a, the sliding movement of the second operation plate 64 is stopped, and the approach arm 60 is located at a position where both ends of the binding tool 13 are brought close to the torsion arm 70. Retained.

  From this state, when the second operating plate drive gear 65 is further rotated in the direction of the arrow R2, the gear portion 71a of the coaxial intermittent drive gear 71 enters the rotation restricting recess 72b and the rotation restricting portion 71b enters the rotation position. Meshes with the small gear 72a of the timing gear 72 that has been restricted, and the rotation restricting portion 71b is disengaged from the rotation restricting recess 72b.

  Thus, the timing gear 72 and the pair of bevel gears 73 are rotated in the direction of the arrow by the rotation of the intermittent drive gear 71, the torsion arm 70 is rotationally driven in the direction of the arrow W3, and both ends of the binding tool 13 are twisted to bind The tool 13 is fastened.

  In the process in which the torsion arm 70 is rotationally driven, the first operating plate drive gear 34 is rotating, but the first operating plate 32 is not slid due to the shape of the cam groove 34a. , And held at the position abutted against the abutment guide 31.

  FIG. 27 is an operation explanatory view showing the binding machine in the process of releasing the bags after the binding is completed by returning the respective parts to the origin.

  When the intermittent drive gear 71 is rotationally driven until both ends of the binding tool 13 are twisted and tightened a predetermined number of times, the gear portion 71a of the intermittent drive gear 71 is separated from the small gear 72a of the timing gear 72, and the rotation restricting portion 71b is rotated. The rotation of the timing gear 72 is restricted by entering the restriction recess 72b, and the rotation of the torsion arm 70 is stopped.

  When the second operation plate drive gear 65 is further rotated in the direction of the arrow R2 from the state where the gear portion 71a of the intermittent drive gear 71 is separated from the small gear 72a of the timing gear 72, the second operation plate 64 is illustrated. As shown in FIGS. 21 (b) to 21 (c), the guide roller not to be guided is guided by the other operating portion 65d of the cam groove 65a, so that the second operating plate 64 slides in the direction of arrow F4. To return to the origin position H2. As a result, the link center 64a to which the first link 61 is coupled slides together with the second operating plate 64, and the pair of arm arms 60 are rotationally driven in the direction of the arrow W4 with the shaft 60a as a fulcrum, thereby returning to the origin. Then, the binding tool forming claw portion 60c is opened.

  Further, when the first operating plate driving gear 34 is further rotated in the direction of the arrow R1 from the state where the gear portion 71a of the intermittent driving gear 71 is separated from the small gear 72a of the timing gear 72, the first operating plate 32 is driven. The guide roller (not shown) is guided by the other operating portion 34d of the cam groove 34a as shown in FIGS. 21 (b) to 21 (c), so that the first operating plate 32 slides in the direction of arrow F5. Move and return to the origin position H1. As a result, the curl guide 30 moves in the direction of the arrow F6 and moves away from the abutment guide 31.

  When the curl guide 30 is separated from the abutment guide 31, the tag 1 </ b> A is attached to the bag 14 with the binding tool 13 and therefore does not follow the operation of the curl guide 30. As a result, as shown in FIG. 13B, a force is applied in the direction of pulling out the binding tool 13 from the binding tool passage 30c of the curl guide 30, and the binding tool 13 is deformed by the covering material 13b and the binding tool take-out slit 30d. And exits from the binding tool path 30c.

  Therefore, the tag 1A is detached from the curl guide 30, and the bag 14 is bound by the binding tool 13, so that the tag 1A is attached to the bag 14 as shown in FIG.

  Here, when the binding operation of the binding tool 13 is finished and the bag 14 is removed from the mounting space 31c, one tag 1A is transported to the curl guide 30 of the tag holder mechanism 3A by the tag transport mechanism 4A shown in FIG. To do.

  As shown in FIG. 14A, the tag 1 </ b> A conveyed to the curl guide 30 is held by the curl guide 30 after the recess 12 m is locked to the tag hooking claw portion 30 b.

  By performing the above operation, the next bag 14 is set in the mounting space 31c, and when the binding operation is started, the tag 1A is already set in the curl guide 30, and the tag 1A is conveyed and set. Since no operation is required, the processing time can be shortened. The tag 1A may be set after the bag 14 is set. Further, the tag 1A may be manually set on the curl guide 30 without providing the tag transport mechanism.

  As shown in FIG. 6A, in the tag 1A attached by the above-described bundling operation, one bundling tool 13 is passed through two locking holes 11m. The binding tool 13 passed through the locking hole 11m of the tag 1A is wound around a binding part 14a that squeezes a predetermined portion near the mouth of the bag 14, and is twisted at both ends to be fastened. The binding part 14a is bound.

  In the tag 1A, the binding tool 13 is passed through the locking hole 11m, and when the binding part 14a of the bag 14 is bound by the binding tool 13, the portion between the locking holes 11m of the mounting part 11A is bound to the binding tool 13. And attached to the bag 14.

  In the tag 1A, when the binding tool 13 is passed through the two locking holes 11m, and the binding part 14a of the bag 14 is bound by the binding tool 13, the orientation of the information presentation part 10A is the vertical direction along the bag 14 And do not turn sideways.

  Further, since the tag 1A is wound around the binding portion 14a in which the binding tool 13 squeezes the bag 14, the mounting portion 11A is curved. However, since the recessed part 12m is formed in the both sides of the information presentation part 10A between the mounting part 11A and the information presentation part 10A and is connected by the connecting part 12A having a narrower width than the information presentation part 10A, the information presentation The part 10A does not follow the shape of the mounting part 11A, and the information presentation part 10A is not greatly curved. Thereby, the information described in the information presentation unit 10A of the tag 1A is not curved and difficult to recognize.

  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.

  Further, since the tag curved protrusion 30a of the curl guide 30 holding the tag 1A is curved in a convex shape, the tying member passage 30c connecting the two points of the tag curved protrusion 30a is gently curved in a shape close to a straight line. The distance from the tag bending protrusion 30a is made closer.

  That is, when considering a configuration in which the tag is held in a straight line and the binding tool is passed through the two locking holes, the binding tool is passed through the locking hole in one of the tags from a substantially vertical direction, and then the binding tool is moved to the U-shape. Since the path needs to be folded back into the shape and passed through the other locking hole, the required length of the binding tool becomes longer. Accordingly, when the binding tool is twisted by winding around the bag, a gap is generated between the binding tool and the tag, and the binding cannot be sufficiently tightened.

  On the other hand, by curving the tag bending protrusion 30a of the curl guide 30 holding the tag 1A in a convex shape, the tying member passage 30c can be gently bent in a shape close to a straight line. Thereby, the distance between the binding tool 13 passing through the binding tool passage 30c and the tag 1A held by the tag bending protrusion 30a is reduced, and the gap between the tag 1A and the binding tool 13 is prevented from being greatly opened. 13 can be securely fastened.

  The same applies to the tag 1B according to the second embodiment. In the tag 1B, as shown in FIG. 6B, one binding tool 13 is passed through two locking grooves 11n. The binding tool 13 passed through the locking groove 11n of the tag 1B is wound around a binding portion 14a that narrows a predetermined portion near the mouth of the bag 14, and is twisted at both ends to be fastened. The binding part 14a is bound.

  In the tag 1B, since the binding tool 13 is passed through the locking groove 11n, when the binding part 14a of the bag 14 is bound with the binding tool 13, the portion between the locking grooves 11n of the mounting part 11B is bound to the binding tool 13. And attached to the bag 14.

  Similarly to the tag 1A, when the binding tool 13 is passed through the two locking grooves 11n, the tag 1B causes the information presenting part 10B to face the bag when the binding part 14a of the bag 14 is bound by the binding tool 13. 14 in the vertical direction and never in the horizontal direction.

  Moreover, since the tag 1B is wound around the binding part 14a in which the binding tool 13 squeezes the bag 14, the mounting part 11B is curved. However, since the recessed part 12m is formed in the both sides of the information presentation part 10B between the mounting part 11B and the information presentation part 10B, and it is connected by the connecting part 12B having a narrower width than the information presentation part 10B, the information presentation part 10B does not follow the shape of the mounting portion 11B, and the information presentation portion 10B is not greatly curved. Thereby, the information described in the information presenting unit 10B of the tag 1B is not curved and difficult to recognize.

  And since the information presentation part 10B becomes the vertical direction along the bag 14 without curving, the external appearance of the figure which attached the tag 1B to the bag 14 becomes favorable.

  Here, the binding tool 13 is passed through the opened locking groove 11n in the tag 1B. However, in the state where the bag 14 is bound by the binding tool 13, the tag 1B is locked by fitting the groove into the binding tool 13, and the tag 1B. Does not come off the bag 14 easily. On the other hand, if the binding tool 13 that has bound the bag 14 is loosened, the tag 1B can be easily removed from the binding tool 13, so that the unnecessary tag 1B can be easily removed without removing the binding tool 13. be able to.

  FIG. 28 is a perspective view showing a modification of the binding machine of the present embodiment. A binding device 2B according to a modified example includes a feed motor 81 that drives the tag holder mechanism 3B and the binding tool forming mechanism 6B, a torsion motor 82 that drives the binding tool fastening mechanism 7B, and a feed motor (not shown) that drives the binding material transport mechanism 5B. And the bundling operation of the bundling tool is performed with three motors.

  The closing motor 81 rotates the ball screw shaft 83 to slide the bearing portion 84. The bearing portion 84 includes a lock claw portion 84 a that pushes the first operating plate 32 that moves the curl guide 30, and a near roller push portion 84 b that pushes the near roller 63 b of the second link 63 that rotates the near arm 60.

  The locking claw portion 84a is engaged with the first operating plate 32, and the driving motor 81 is rotationally driven, so that when the bearing portion 84 slides, the first operating plate 32 is slid. Further, when the bearing portion 84 moves to a position where the curl guide 30 is abutted against the abutment guide 31, the first operation plate 32 is disengaged and the first operation is performed even if the bearing portion 84 slides. The driving force to the plate 32 is not transmitted.

  The shift roller pressing portion 84b is provided at a position where the lock roller 63b of the second link 63 is pressed when the lock claw portion 84a is unlocked.

  As a result, after the tag 1A is held by the curl guide 30 and the abutment guide 31 as shown in FIG. 7B, the pairing arms 60 can perform the forming operation of the binding tool. The same operation as the bundling operation is realized.

  The torsion motor 82 rotationally drives the torsion arm 70 via the speed reduction mechanism 82a. A feed motor (not shown) rotates the feed roller 50 via a speed reduction mechanism or directly.

  With the above configuration, the curling guide 30 slides and the tag is held between the abutting guide 31 by the predetermined amount of normal rotation operation of the moving motor 81, and the predetermined amount of normal operation of the feed motor (not shown) is performed. The feed roller 50 rotates and the binding tool is conveyed.

  Further, by a predetermined amount of forward rotation of the shift motor 81, the pair of shift arms 60 are closed by the driving force transmitted by the first link 61, the binding tool is cut and molded, and the predetermined amount of the torsion motor 82 is positive. The twisting arm 70 is rotated by the rolling operation, and the binding tool is fastened. Then, the tag is detached from the curl guide 30 by a predetermined amount of reverse operation of the shift motor 81.

<Examples of effects of the binding machine of the present embodiment>
As described above, the binding machine 2A and the binding machine 2B according to the present embodiment use the concave portion 12m of the tag 1A as a positioning unit for passing the binding tool 13 through the locking hole 11m, thereby binding the binding tool 13. By the binding operation of the bag 14 by the above, the tag 1A can be attached together through the binding tool 13 through the two locking holes 11m of the tag 1A. Here, the driving source for driving the mechanism for holding the tag 1A in a predetermined shape, transporting the binding tool 13 through the tag 1A, and binding it is performed by a single motor like the binding device 2A. Alternatively, a plurality of motors may be used as in the binding device 2B.

  Further, the binding machine 2A and the binding machine 2B of the present embodiment can be used as a normal binding machine that binds the bag mouth of the bag 14 with only a binding tool without setting a tag. It is possible to have both functions.

  The operation of manually passing the binding tool through the two locking holes is inefficient and unsuitable for mass production, but the work efficiency is improved by mechanization including the step of passing the binding tool through the locking hole.

  In the above-described embodiment, the binding tool is configured such that a core wire such as metal or resin is covered with a covering material in a tape shape (band shape), but the binding tool is not limited to this configuration.

  For example, a linear member having a circular cross section in a state where the core wire is covered may be used as a binding tool, or a single wire material made of wire or resin may be used. The bundling tool only needs to have appropriate plasticity suitable for twisting and fastening.

  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.
