Description of the Related Art An arch-type banding device having an arch for accommodating a band guide is used in a book packing machine for packing a band of a set of a specified number of copies with a band. ing. The arch type strapping device is provided on the side of the lateral feed section formed at the front end of the transport path of the print group, and moves the transport group on the transport path to reach the lateral feed section. Traverse into the arch of the strapping device.

[0003]

Since this book packing machine is provided with an arch type banding device on the side of the conveying path, the whole device becomes large. In addition, a conveying member (for example, a lower fork and a book end fork) is provided at the lateral feeding section
Since it is necessary to switch the holding of the printing book group by the holding by the lateral feed member (for example, the lateral movement guide plate), the structure and operation control must be complicated. In addition, there is a risk that the print group will be disturbed or damaged during switching and lateral feeding.

Therefore, an object of the present invention is to provide a book packing machine which is suitable for downsizing, has a simple structure and operation control, and which does not cause disturbances or scratches on the book group.

[0005]

In order to achieve this object, a print packing machine according to the present invention forms a set of prints containing a predetermined number of copies by aligning the prints sent from a rotary press on a conveying path. , One of which crosses the passage of the book group by linearly moving the book group along the conveying path and connecting the ends of the two bands drawn from each of the pair of band supply reels. , The band is moved around the brush group and wound in a U-shape, and then a pair of sealers are used to pull the bands on both sides toward each other along the rear end surface of the group to print. A closed loop for the band that encloses the group is formed, and cutting, melting and crimping of the melting surface are performed by a heater built in one sealer and a pusher built in the other sealer. It is packed with a moving sealer type banding device along the rear end face that is designed to be carried out.

[0006] Crossing the passage of the print group does not limit the direction in which the band is stretched. Therefore, the case of stretching the band in the vertical direction is naturally included.

It is preferable to dispose two bands crossing the passages of the pair of sealers and the printing group in a direction perpendicular to the moving direction of the printing group, and to adjust the distance between the two pairs of the sealing and the bands. It is effective to make it possible.

Further, it is preferable that the copy book group is configured to move while being compressed on the conveying path.

Further, in front of the sealer, a front pressing member and a rear shutter for sandwiching and compressing the front end surface and the rear end surface of the printing group are provided. This rear shutter has a rear end surface of the printing group. It is effective that the front press member descends after passing and the front press member moves rearward after the rear shutter descends.

[0010]

Function: The packing work can be completed without switching the moving direction of the copy book group.

If a pair of sealers and two bands crossing the passage of the book group are arranged in the direction perpendicular to the moving direction of the book group,
If two bands can be hung on the group of printed books at the same time, and the distance between them can be adjusted, the distance between the two bands hung can be made proper.

By moving the printing book group while compressing it, at least a part of the necessary compressing work can be performed during transportation.

By providing the front pressing member and the rear shutter, it is possible to sufficiently compress the brush group when the band is put on.

Line up. The conveyor belt 5 moves forward at a speed in synchronization with the rotational speed of the impeller 1 so that the sequentially fed copy sheets are lined up on the conveyor belt 5 without difficulty.

A bookend fork 7 provided to support the front end of the booklet group from the process of forming the booklet group is attached to a bookend fork chain 9 and a guide 11 is provided.
Although it is configured so that it can be moved along, it is weakly braked in the forward direction (direction of arrow X) and is gradually pushed forward by being pushed by the group of printing books.

When a predetermined number of copies of the books aligned on the conveyor belt 5 reach a predetermined number, the ejecting cylinder 13 ejects the partitioning fork 15, and the partitioning fork 15 is formed.
And a bookend fork 7 are formed to form a group of printed books. The sorting fork 15 is a sorting fork chain.
It is configured to be movable along a guide (not shown) of a side plate by being connected to a pin 17 and, after being ejected, supports the front end of the next printing book group to be pushed by this printing book group. And gradually move forward (see FIG. 2: FIG. 2 shows the state of formation of the printing book group).

When the sorting fork 15 is pushed by the group of printing sheets to be formed next and moves forward to a certain position, the lower fork 19 (see FIG. 2) that has been waiting at this position is guided by the guide 21. And moves up between the previous and next brush groups (in FIG. 1, the lower fork 19 is shown advanced from a certain position and raised). Lower fork 1
9 is connected to a lower fork chain 25 to which a joint block 23 is fixed.
3 is movably attached to the guide 27. When the joint block 23 is pushed by the moving member 31 of the rodless cylinder 29 and retracts in the direction of the arrow Y, the lower fork 19 moves forward along the guide 11 to move the front print group along the rear end face. It is conveyed to the mold band hanging device 33. In this conveying process, the bookend forks 7 are strongly broken, and the group of printing books is conveyed while being compressed. The lower fork 19 is a sealer type banding device 33 in which the book end fork 7 moves along the rear end face.
Immediately after it reaches the standby position of the front press member 35 and stops, it stops. Therefore, the copy book group is further compressed between the lower fork 19 and the book end fork 7 / front pressing member 35. In addition, the next copybook group is divided into Fork 1
