  The side guide 23 is connected to the link 24, and the link 24 rotates around the rotation center 24a so that the side guide 23 is retracted upward to release the opening 22a. The link 24 is connected to the push bar 25, and rotates when the push bar 25 is pressed by the binding head 7.

  The binding head 7 is provided adjacent to the shift guide 6, and the overlap portion of the band B is bound by the shift guide 6 using a binding tool such as caulking or band seal. The bundling head 7 that has been widely used can be used as it is, and in addition to bundling (caulking), various operations such as fixing and releasing the band B, tightening and cutting the band B can be performed. it can.

  The bundling head 7 has a work space 26 in which the overlapping portion of the band B is inserted and the band B is fixed and bound in order to bind the overlapping portion. The work space 26 includes an opening 26 a at a position facing the opening 22 a of the guide space 22 of the shift guide 6. The work space 26 is configured to have a large width on the opening 26a side, and facilitates reception of the overlap portion. As shown in FIG. 5, the openings 22a and 26a are very close to each other, and the overlapping head is transferred to the binding head 7 through the opening when the binding head 7 and the shift guide 6 are moved. .

  As shown in FIGS. 6 and 7, the shift guide 6 and the bundling head 7 are configured to be able to translate in the width direction of the band B by shift cylinders 28 and 29, respectively. 6 is a diagram showing a state in which the shift guide 6 is arranged in the notch portion, and FIG. 7 is a diagram showing a state in which the binding head 7 is arranged in the notch portion.

  The shift guide 6 is provided in the cutout portion 4a of the loop guide 4 by the guide frame 8, and is arranged so as to be movable along a guide bar 30 extending in the width direction of the loop guide 4. A shift guide shift cylinder 28 is provided. Translate by.

  On the other hand, the binding head 7 is connected to a support link 32 supported by a support shaft 32a via a link 31 provided on the upper surface thereof. The bundling head shift cylinder 29 is connected to the support link 32. The joining position of the shift cylinder 29 and the support link 32 is provided on the opposite side of the binding head 7 with the support shaft 32a interposed therebetween.

  The support link 32 is provided so as to be movable in parallel along the pair of guide bars 33 by expansion and contraction of the bundling head shift cylinder 29. The guide bar 33 is connected to the guide frame 8 and supported by a guide support member 34 that is integrally formed with the guide portion 34a. A restriction link 35 is slidably provided on the guide support member 34, and stoppers 35a and 35b are provided at both ends. The restriction link 35 is connected to the link 31, and the link 31 is inclined with respect to the support link 32 according to the position of the restriction link 35.

  The operation of the binding head 7 is as shown in FIGS. 6 to 7, that is, when the binding head 7 moves to the cutout portion 4a, the support link 32 is pushed by the binding head shift cylinder 29 and cut. Move in the missing direction. At this time, the restriction link 35 also moves together with the link 31, and the relative position with respect to the guide support member 34 moves to the tip side. For this reason, the binding head 7 moves in the direction of the notch of the loop guide 4 in parallel, and the binding head 7 is pressed against the shift guide 6.

  At this time, the shift guide shift cylinder 28 maintains pressure in the direction in which the shift guide 6 is pressed toward the bundling head 7, but the pressure of the shift guide shift cylinder 28 is limited to the bundling head shift. The pressure is set to be smaller than the pressure of the cylinder 29. As a result, the shift guide shift cylinder 28 is pushed down by the pressure difference. With this configuration, the shift guide 6 and the bundling head 7 are more closely attached, and the overlap portion is delivered more smoothly.

  As described above, due to the contact between the binding head 7 and the shift guide 6, the binding head 7 pushes the push bar 25 of the shift guide 6, the side guide 23 opens the opening, and the band B operates the binding head 7. Delivery to the space 26 becomes possible. After the delivery of the band B bundling head 7 to the work space 26 is completed, the shift guide shift cylinder 28 moves the shift guide 6 away from the cutout portion 4a.

  On the other hand, when the binding head 7 is retracted from the cutout portion 4 a of the loop guide 4, the support link 32 connected to the binding head shift cylinder 29 is pulled toward the binding head shift cylinder 29. As described above, when the caulking portion of the band B is caught in the work space, the band B is in the work space of the bundling head 7 depending on the positional relationship among the support shaft 32a, the support link 32, and the power point of the shift cylinder 29. The caulking portion of the inner band B and the engaging portion of the metal fitting of the bundling head 7 become resistance, and only one side having low resistance is detached from the band B, and the bundling head 7 is inclined. The inclination angle of the bundling head 7 is regulated by the link 31 hitting the stopper 27. The inclination regulation stopper 27 is provided at the end of the support link 32, and regulates the inclination angle between the support link 32 and the link 31 by contacting the link 31.

  Accordingly, the binding head 7 is retracted from the cutout portion 4a in an inclined state, and the binding of the bound band B can be easily released. That is, when the support link 32 is pulled by the bundling head shift cylinder 29 while the bundling head 7 is inclined, the inclination angle of the bundling head 7 changes. When the binding head 7 moves as a whole in this inclined state, the portion that has been caught in the binding head 7 is detached from the binding head 7.

  When the proximal end stopper 35b and the guide support member 34 come into contact with each other (see FIG. 8), the bundling head 7 rotates in the direction in which the inclination returns, with the connection shaft 31a between the restriction link 35 and the link 31 as the rotation center. A stopper 7a is provided on the opposite side of the support shaft 32a of the power point of the shift cylinder 29 so that the bundling head 7 moved in an inclined state comes into contact with the bundling head 7 when it returns to its original state. Is arranged.

  As described above, the binding unit 3 is configured to be movable up and down as a whole. FIG. 9 is a diagram illustrating a configuration of a vertical movement mechanism of the binding unit. In FIG. 9, the description of the loop guide 4 is omitted to facilitate understanding of the structure.

  As a configuration for moving the binding unit 3, a pair of guide rods 36 provided on the main frame 2 and sliders 38 and 39 configured to be slidable with respect to the guide rods 36 are provided.

  The guide rod 36 is fixed to the main frame 2 so that the moving direction of the sliders 38 and 39 is the vertical direction. The sliders 38 and 39 are connected to the loop guide 4 at connection portions 38a and 39a, respectively. A loop guide elevating cylinder 37 is connected to the slider 38. When the loop guide elevating cylinder 37 expands and contracts, the slider 38 moves up and down.

  Further, as described above, the loop guide 4 is provided with the shift guide 6, the bundling head 7, the guide frame 8, and the like.

  The balance weight 42 is wound around a gear 43 configured to be freely rotatable, and is connected to the loop guide support portion 40 by a connection chain 41. The balance weight 42 keeps the balance with the loop guide 4, and the force for vertical movement by the loop guide lifting cylinder 37 can be reduced.

  Next, the operation of the automatic binding device according to the present embodiment will be described. First, the transport conveyor 102 is first operated to move the object 100 to a predetermined position. Thereafter, the feed roller 5 is operated to feed the band B by a predetermined length. The feed length of the band B is set to such a length that the overlap portion is surely formed by the length measuring mechanism of the feed roller 5 after the front end of the band B is detected by the photoelectric sensor 21. That is, the length in which the overlap portion is formed from the photoelectric sensor 21 through the inner periphery of the loop guide 4 is determined by the size of the device, and can be a constant length.

  Next, the shift guide shift cylinder 28 and the bundling head shift cylinder 29 are driven to retract the shift guide 6 and advance the bundling head 7. At this time, as described above, the overlapping portion of the band B is transferred to the work space 26 of the binding head 7.

  Next, the bundling unit 3 is lowered by operating the loop guide lifting cylinder 37 so that the bundling head 7 is positioned in the vicinity of the upper surface of the bundling object 100. Further, the band chuck cylinder 16 is driven to fix the vicinity of the tip of the band B, and the guide release cylinder 13 is driven to open the guide groove 11.

  Next, the feed roller 5 is rotated in the reverse direction, and the band B corresponding to the extra length is pulled back by a predetermined length, and then the tip of the band B is fixed by the bundling head 7. The pull back length of the band B corresponding to the extra length is measured by measuring the rotation of the pinch roller 19 with an encoder. Thereafter, the band chuck cylinder 16 is driven to release the vicinity of the tip of the band B, and the band B is tightened by the binding head 7 so as to be wound around the object to be bound with a predetermined pressure.

  The band tightening is confirmed by comparing the relationship between the rotation of the driving roller 18 and the pinch roller 19 and the rotation of the motor that drives the driving roller 18. That is, the drive roller 18 is provided with a torque limiter, and when the tightening of the band B has a predetermined strength even though the motor driving the drive roller 18 is driven, the band B Since it is not pulled back, the driving roller 18 and the pinch roller 19 do not rotate, and the feed of the band B is not recognized by the encoder. Therefore, the tightening of the band B can be confirmed by comparing the driving roller 18 and the pinch roller 19 with the presence or absence of rotation of the motor.

  In the present embodiment, the band B is tightened by the bundling head 7. However, for example, both the pulling back and the tightening for the extra length may be performed by the feed roller 5.

  When the tightening of the band B is completed, the binding head 7 is operated to bind the band B and cut the band B, and then the binding head 7 releases the band B.

  Next, the feed roller 5 is operated to rewind and feed the band B to the position of the photoelectric sensor 21 and reset the band B length. Next, the binding head shift cylinder 29 is driven, the binding head 7 is moved backward, and the band B is pulled out from the work space of the binding head 7. In this state, the binding head 7 is detached from the band B, so that the binding unit 3 is raised. Next, the shift guide shift cylinder 28 is driven to advance the shift guide 6.

  After the bundling operation, when the bundling head 7 is retracted and the band B is pulled out from the work space, the band B is locked to the bundling head and the bundling head 100 and the bundling head 7 are brought together with the bundling head 7. May move in the direction of movement. This is likely to occur when the object to be bound 100 is supported by the transport roller 103 or when the weight of the object to be bound 100 is light.

  In order to prevent this problem, in this embodiment, band stoppers 50 are provided on the upstream side and / or the downstream side of the binding head. The band stopper 50 locks the band B located outside the work space of the binding head 7 so that the binding object 100 is not displaced when the binding head 7 is detached from the binding object 100. As the position of the band B to which the band stopper 50 is locked, for example, as shown in FIG. 10, after the band B is bound, the lower end of the binding head 7 is between the band B and the upper surface 100a of the object 100 to be bound. 7b can be lifted to raise the floating portion 105 of the band B where the band B is floating from the object to be bound 100, and by hooking that portion, in FIG. It is intended to prevent the object to be bound 100 from moving.

  Specifically, the band stopper 50 can be provided on the shift guide 6 or the end guide 4b as shown in FIG. 11 or FIG.

  FIG. 11 is a diagram illustrating a configuration example when the band stopper 50 is provided in the shift guide 6. In FIG. 11, the band stoppers 50 are provided at both ends of the shift guide 6, and the floating portions 105 of the band B bound by the upstream side and the downstream side of the binding head 7 are hooked by the band stopper 50, The bundling object 100 is prevented from moving while the bundling head 7 shown in FIG.

  FIG. 12 is a diagram illustrating a configuration example when the band stopper 50 is provided in the end guide 4b. In FIG. 12, the band stopper 50 is provided on the end guide 4 b located at the end of the loop guide 4. The end guide 4b guides the band B to the cutout portion 4a of the loop guide 4 and is located upstream of the bundling head 7. Therefore, the end guide 4b is positioned on the upstream side of the bundling head 7. The floating portion 105 is hooked by the band stopper 50 so that the object to be bound 100 does not move while the binding head 7 is retracted as indicated by an arrow 92.

  The band stopper 50 can be attached not only to the end guide 4 b but also to the loop guide 4, particularly the downstream side of the bundling head 7.

  As described above, according to the automatic binding device of the present embodiment, the band overlapping portion can be reliably created without causing the band to be caught by the binding head 7, and this can be received by the binding head 7. By passing, reliable bundling operation can be performed.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, the band B may be made of a synthetic resin or the like, and in this case, the band B can be applied by using a bundling head as a synthetic resin sealer or the like.
