FIG. 10 is an explanatory view when the binding string is hooked on the hanging claw by the string removing mechanism. FIG. 11 is an explanatory view when the binding string is pulled out from the hanging claw by the string pulling mechanism. FIG. 12 is an explanatory diagram of hooking and pulling out the binding string by the string pulling mechanism when the claw width expansion / contraction mechanism 50 is reduced. FIG. 13 is an explanatory view of hooking and pulling out the binding string by the string pulling mechanism when the claw width expansion / contraction mechanism 50 is extended. As shown in FIGS. 10 and 11, the string removing mechanism 52 has a string hooking member 52a, is connected to a hanging claw 48 on the lower surface via a first slide portion 52b, and is slidably configured.

Then, by controlling the rotation of the motor 50j, the hanging claw 48 is pressed onto the bound object 12 so as to straddle the binding line 21 of the binding machine 22 in a state where the hanging claw 48 protrudes from the string hooking member 52a (see FIG. 10). When they are tied together, the hanging claw 48 is sandwiched between the binding string 14 and the object to be bound 12. On the other hand, when the hanging claw 48 is retracted into the string hooking member 52a (see FIG. 11), the binding string 14 is suppressed by the string hooking member 52a and comes off to release the hook. With such a configuration of the string removing mechanism 52, the binding string can be removed from the hanging claw regardless of the expansion and contraction of the claw width of the hanging claw.

(Modification example Claw width expansion / contraction mechanism 50A)
FIG. 14 is an explanatory view of the claw width expansion / contraction mechanism 50A of the modified example, (1) shows when the claw width is extended, and (2) shows when the claw width is expanded / contracted. As shown in the figure, the claw width expansion / contraction mechanism 50A of the modified example adopts a fitting structure of a rack gear and a pinion gear. In a more specific configuration, the pinion gear 60 and a motor (not shown) that rotates the pinion gear 60 in the forward and reverse directions are arranged at the center of the claw body 54. A pair of rack gears 62 that mesh with the pinion gear 60 are connected to a string hooking member 52a (hanging claw 48). The rack gear 62 is set to be approximately half the length of the claw body 54. The pair of rack gears 62, one end side of which is connected to each of the pair of string hooking members 52a, are arranged so as to sandwich the pinion gear 60 on the other end side. Further, the string hooking member 52a is configured so that the slide rail 50f can be slidable. With such a configuration, when the pinion gear 60 is rotated in the direction of arrow A, the pair of hanging claws 48 can move in a direction in which they are separated from each other, and the claw width can be extended (see FIG. 14 (1)). On the other hand, when it is rotated in the direction of arrow B, the pair of hanging claws 48 can move in the direction of approaching each other to reduce the claw width (see FIG. 14 (2)).

The cross-binding method using the cross-binding device having the above configuration will be described below.
FIG. 15 is a processing flow of the cross binding method.
(Step 1)
The carry-in conveyor 16 and the transport belt 25 are operated to carry in the bound object (see FIG. 2).
(Step 2)
The first stop sensor 28 detects the first bundled object 12 and the conveyor belt 25 stops. The second stop sensor 30 detects the second bundled object 12 and the carry-in conveyor 16 stops (FIG. 6). 3).
(Step 3)
The push-in guide 26 of the feeder 24 moves from the standby position (see FIG. 2) to the push-in start position, moves so as to be sandwiched between the two rear corners of the bound object on the transfer belt 25, and comes into contact with the transfer belt. Alignment is performed so that the longitudinal direction of the 25 and the center position of the bound object 12 in the longitudinal direction are aligned (see FIG. 3).

(Step 4)
The object to be bound 12 on the transport belt 25 is pushed by the push-in guide 26 to the binding position on the binding machine 22 (see FIGS. 4 and 5).
(Step 5)
The claw body 54 (hanging claw 48) in the standby position above the binding position of the binding machine 22 is lowered by the vertical movement mechanism 44 to press the bound object 12 with a predetermined pressure. After that, the binding machine 22 circulates the binding string 14 in the lateral direction of the object to be bound 12 and first binds the bound object 12 together with the hanging claws 48 (see FIGS. 16 and 17).
(Step 6)
After the object 12 at the binding position is slightly moved upward by the vertical movement mechanism 44, it is rotated 90 ° clockwise by the rotation mechanism 46. Then, the lateral movement mechanism 42 moves the side surface of the object to be bound 12 in the lateral direction so as to coincide with the side surface orthogonal to the binding line 21 of the binding machine 22 (see FIGS. 18 and 19). In the binding machine 22, the position for connecting the strings (reference at the end of the main body, etc.) is determined for each device. The movement is necessary because there is a difference in length between the lateral direction and the longitudinal direction of the object to be bound 12. Next, the object to be bound 12 is lowered by the vertical movement mechanism 44 and placed on the upper surface of the binding machine 22. The hanging claw 48 is removed from the binding string 14 by the string removing mechanism 52.
In parallel, the second bundle of objects 12 is moved from the carry-in conveyor 16 to the transfer belt 25, and the first stop sensor 28 detects the second bundle of objects 12 and the transfer belt 25 stops. The second stop sensor 30 detects the third bundle of objects 12 and stops the carry-in conveyor 16.

(Step 7)
After the hanging claw 48 is slightly moved upward by the vertical movement mechanism 44, it is rotated 90 ° to the left by the rotation mechanism 46. The claw width expansion / contraction mechanism 50 changes the claw width of the hanging claw 48 to the width in the longitudinal direction of the bound object 12. Then, the suspension claw 48 is moved by the horizontal movement mechanism 42 on the bound object 12 arranged in the longitudinal direction along the binding line 21. The claw body 54 (hanging claw 48) is lowered by the vertical movement mechanism 44 to press the bound object 12 with a predetermined pressure. After that, the binding string 14 is circulated in the longitudinal direction of the object to be bound 12 by the binding machine 22 and bound together with the hanging claw 48 to form a cross binding (see FIGS. 20 and 21).
In parallel, the pushing guide 26 of the feeder 24 moves from the standby position (see FIG. 2) to the pushing start position, and aligns the center positions of the transport belt 25 in the longitudinal direction and the bound object 12 in the longitudinal direction. ..

(Step 8)
The cross-bound object 12 is slightly moved upward by the vertical movement mechanism 44, and then moved to the carry-out conveyor 18 by the horizontal movement mechanism 42. On the upper surface of the carry-out conveyor 18, the hanging claw 48 is removed from the binding string 14 by the string removing mechanism 52, and the bound object 12 is dropped onto the conveyor and conveyed to the outside (see FIGS. 22 and 23). After that, the claw width expansion / contraction mechanism 50 changes the claw width of the hanging claw 48 to the width length of the bound object 12 in the lateral direction. Then, it moves to a standby position above the binding position of the binding machine 22.
In parallel, the bound object 12 on the transport belt 25 is pushed by the pushing guide 26 to the binding position on the binding machine 22.
After that, the same operation as in step 5 and subsequent steps is repeated.

According to the present invention as described above, the object to be bound 12 can be cross-bound on one binding machine 22, and the space of the entire device can be saved and the cost can be reduced as compared with the conventional configuration. ..
Further, the claw width of the hanging claw 48 can be switched in a short time according to the longitudinal direction or the lateral direction of the object to be bound, and the cross bundling operation can be performed quickly.
In the cross binding device 10 of the present invention, the binding order of the objects to be bound 12 in the longitudinal direction and the lateral direction may be either. Further, it is also possible to have a configuration in which either the longitudinal direction or the lateral direction of the object to be bound 12 is first bound and then discharged to the carry-out conveyor 18.
The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
Further, the present invention is not limited to the combinations shown in the embodiments, and can be implemented by various combinations.
