[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transport finishing device used in a finishing process for postcards or the like, in which a plurality of printed materials, in which a plurality of same or different designs are printed in a row and a column direction, are stacked in one sheet. The present invention relates to a technique of banding a paper block cut into units.

[0002]

2. Description of the Related Art As a method of manufacturing a printed matter in which a plurality of same designs are printed in a row and a column direction on a single sheet, for example, as a method of manufacturing a postcard, first, a large number of one-sided designs of a postcard are arranged on a printing plate. Is attached to a printing machine, and a large number of designs are printed on relatively large-sized paper. Next, when the delivery form of postcards is a fixed number of postcards stacked, banded, sealed and delivered, first,
The sheets on which the large number of designs for the required number of sheets are printed are stacked, and the manual work of the worker is performed using respective dedicated devices such as a weighing machine, a paper aligning machine, a cutting machine, a banding machine, and an encapsulating machine. If this is done, the work efficiency is low and many workers are required.
For example, an automatic transfer finishing device disclosed in, for example, Japanese Patent No. 1661 has been developed, thereby saving labor.

[0003] In addition, a general automatic transport finishing device is often composed of a paper feeding unit, a paper measuring unit, a strip cutting unit, a banding unit, a small cutting unit, and a sealing unit. For example, as shown in FIG. 5, a sheet feeding unit feeds a stack of sheets of the same design printing paper 1 on which the same design 2 such as a postcard is printed in m × n sides (m rows × n columns). (Not shown), the paper weighing unit A is supplied with a fixed number of k sheets, for example, 100 sheets.
After a certain number of sheets of the fixed-quantity laminated printing paper 3 have been extracted and cut out, the strip cutting section B cuts the paper into blocks 4 in rows in parallel with the sheet conveyance direction. M when cut into strips (5 in Fig. 5)
At this stage, a postcard design for n (5 in FIG. 5) faces is arranged in one paper block 4 at this stage. Further, the paper block 4 is finished into a small block 5 having a size of one postcard. However, paper block 4
When cut into small pieces as it is, k sheets (for example, 100 sheets)
Since the printing papers are stacked, the small blocks 5 may be broken or scattered during the cutting or during the transportation of the small blocks 5 to the next process. Therefore, the strap C
It is necessary to attach the band 6 before cutting the paper block 4 into small pieces, and then tighten and fix it to a certain extent. In addition, the belts 6 are grouped in a fixed quantity to facilitate quantity management, and are often delivered as they are. The banding is performed at the n (5 in FIG. 5) positions since the postcard design has n (5 in FIG. 5) faces in the column direction in the state of the paper block 4. At the small cutting section D, the paper block 4 is n (FIG. 5).
Then, it is divided into 5) small blocks 5. Then, the small block 5 is sealed by a packing material such as paper 7 at the sealing portion E.

As shown in FIG. 6, a general method of banding the paper block 4 is, for example, as shown in FIG. Cutting blade 11, 1 of the paper cutting section
The sheet is conveyed to 1 'and cut into paper blocks 4 in rows. The cut paper block 4 is first moved on the second lower transport table 13 to a position a where the chain can be transported by the pull-out gripper 14, and then the drive motor 1
By the pusher 18 provided on the transport chain 17 supported and rotated by the guide rollers 16 and 5, the transport is carried in the direction of the arrow to the position b of the elevator plate 19, and is transported upward by the elevator plate 19. Above the second lower transport table 13, a band reel 21 around which a tape 20 serving as a band is wound in a roll shape is provided, and a guide roller 22, drawing rollers 23 and 23 ', and a band gripper 24 are arranged in this order. Is drawn. Furthermore, the tape 20 is pulled in the direction of the arrow by the band gripper 24 from the feeding rolls 23, 23 'to a predetermined position, and is always cut to the same length by the feeding rolls 23, 23'. For this reason, as shown in FIG. 7, the paper blocks 4 in rows are raised by the elevator plate 19 in the direction of the arrow to the position where the tape 20 is stretched, and the paper blocks 4 are brought into contact with the tape 20 and the elevator plate 19 After the paper block 4 and the tape 20 are sandwiched from above and below by the band holding plate 25 descending from above, the tape 20 is cut by the feeding rolls 23 and 23 '. Accordingly, the cut tape 20 is placed on the paper block 4 and is moved to the upper banding portion while being sandwiched between the band holding plate 25 and the elevator plate 19.

As shown in FIG. 8, the paper block 4 having moved to the banding portion is moved down by the band front pressing plate 26 to abut against the front surface of the paper block 4, and then the elevator is moved by the center plate 27 and the back plate 28. Plate 1
9, the entire frame 30 moves in the direction of the arrow while abutting the band holding plate 29, and moves to the heater unit 32 for banding the upper transfer table 31, as shown in FIGS. 9 and 10. As shown in the drawing, after the tape 20 is welded by heat, the tape 20 is sent to the next small cutting process. Therefore, by repeating this process intermittently, banding is automatically performed on the paper blocks 4 in units of rows.

[0008] Further, the banding method will be described in detail. As shown in FIG. 11, a strip-shaped paper block 4 and a tape 20 forming a band are formed by a band holding plate 25 and an elevator plate 19.
Between the center plate 27 and the back plate 2
8 is temporarily lifted above the upper surface. Next, FIG.
As shown in FIG.
After pressing, the band holding plate 25 and the elevator plate 1
9, the paper block 4 gradually descends, and at the same time, the center plate 27 and the back plate 28 move in the directions of arrows A and B, respectively.
, The paper block 4 is supported instead of the elevator plate 19, and a tape 20 is wound around the paper block 4.
Engulf. Next, the tape 20 is squared by the band holding plate 29 and the band square plate 33 provided at the lower end thereof, and the entire frame 30 moves to the heater 32 while holding the paper block 4. At the same time, the center plate 27 and the back plate 28 also move in the same direction as the frame.

At this time, the method of banding the lower part of the paper block 4 is as follows. First, the tape lower part 20a is bent at the center plate tip part 27a, and then the other tape lower part 2a is bent.
Ob is bent and wound at the back plate tip portion 28a, and at the same time, is fixed by the band back pressing plate 29 and the band squaring plate 33. Therefore, the banding plate 3
Reference numeral 3 denotes a paper block as shown in the enlarged view of FIG. 12 (a), passing through the banding plate forming grooves 35a, 35b, 35c provided on the back plate 28, the center plate 27, and the upper transfer table 31, respectively. The tape at the end 4b moves without being loosened.

On the other hand, as shown in the enlarged views of FIG. 13 and FIG.
As the paper is conveyed in the direction 2, the tape is gradually wound around the lower portion (rear end) 20b of the other tape, and the portion where the tapes 20a and 20b overlap each other is thermally welded by the heater portion 32. However, as shown in the enlarged views of FIGS. 14 and 14 (a), the tape wrapping state of the paper block end 4a is such that the tape 20c is loosened during the conveyance due to the absence of the square holding plate, and the tape slackening portion is not provided. 20c may occur. For this reason, a tape holding plate 36 having a large frictional force such as rubber 36 is stuck on the upper transfer table 31, and the tape holding plate 36 and the tape 20 are attached.
The tape is tightened by the friction of a. But,
When the tape holding plate 36 is attached to the upper transfer table 31 to increase the tightening strength, there is a problem of abrasion or peeling due to friction, so that stable banding is not performed. In addition, since the tape holding plate 36 is attached near the heater 32 because of the end band squaring plate grooves 35a, 35b, and 35c, the tape holding plate 36 may be deformed by heat. It also requires periodic replacement. As described above, when the tape forming the band is not sufficiently tightened, the stacked paper blocks 4 may be displaced in the subsequent small cutting and may be collapsed even in the conveyance after the small cutting, and the automatic conveyance finishing device may be used. There has been a problem that the heavy defect detecting device frequently operates and stops at each part, and the entire line is stagnated, which hinders delivery.
