Description

[Detailed description of the invention] In this invention, a plurality of rotating shafts 2 are arranged in parallel at intervals perpendicular to the paper feeding direction on the underside of a paper feeding slide 1, and one end of each rotating shaft 2 is synchronously The pulley 3 that rotates is fixed to the shaft,
In addition, drive rolls 4 are fixed to each rotating shaft 2 to such an extent that the trend surface of the rolls 4 slightly protrudes upward from the through hole 5 formed in the slide table 1, and the drive rolls 4 are mounted on the slide table 1. A plate body I is provided with idle rolls 6 that are in pressure contact with each driving roll 4, and a small gap 8 is formed between the plate body 7 and the slide table 1, and the plate body 70 is provided on the left and right sides on the paper supply side. The paper raising pieces 10 and 10 are attached to the slide table 1 with small gaps 9 and 9 at both ends.
A paper folding plate 11.11 is horizontally arranged on the sliding table 1 with a small gap 12.12 formed on the same side and opposite to the above paper folding pieces 10 and 100 on the paper sending side, and further the same folding plate 11 This invention relates to a book cover folding device which is provided with a pair of rolls 4' for forming creases which rotate synchronously with the drive roll 4 on the paper delivery side of .11.

In the embodiment shown in the drawings, a synchronous belt (timing belt) 13 is wound around each of the pulleys 3, and one belt 13' of the plurality of synchronous belts 13 is connected to a drive motor 14.
0 pulley 15.

A plurality of drive rolls 4 are fixedly fixed in the axial direction of each rotating shaft 2 at equal intervals.

The idler roll 4 6 is made of rubber and is in pressure contact with the drive roll 4 to form a pair of rolls, and is fixedly fixed to a shaft 16 rotatably supported on the plate 7 .

The idle roll 6 is pivoted and fixed by protruding slightly downward from a through hole 17 formed in the plate body 7, opposite to the direction in which the trend surface of the driving roll 4 slightly protrudes upward from the through hole 5. be done.

That is, the gap 8 between the plate body 7 and the sliding table 1 is a small gap formed by the sum of the protrusions of the drive roll 4 and the idler roll 6, which protrude vertically from the through holes 5 and 17. Then, paper is inserted into this gap 8.

It is preferable that the end of the paper supply port of the plate γ be bent upward 18 to facilitate the insertion of paper.

Furthermore, the plate body 7 and the slide table 1 are plates made of synthetic resin or metal, and due to the characteristics of the material, the plate body 7 is capable of vertically moving up and down with the hissing portion 19 as a fulcrum. It is T-shaped and has a paper folding board 1 in the center which will be described later.
Oblique sides ?' and 7' parallel to the oblique sides 11'' of 1 and 11 are formed.

The paper raising piece 10.10 is a right triangular plate having an inclined side 10' rising toward the paper delivery side.

There is a gap 12. between the paper folding plate 11.11 and the sliding table 1.
12 is fixed on the sliding table 1 via a forming plate 20 (FIG. 3), and the oblique side 11'' extends from the paper supply side ends 11', 11' of the plates 11, 11 inward on the paper delivery side. , 11”.

The pair of rolls 4' for forming creases is fixed to the respective rotating shafts 2 and 16 of the driving roll 4 and the corresponding idle roll 6 in pressure contact therewith in the same relationship as the rolls 4 and 6, This pair of rolls 4' is provided on the extension line of the right triangular paper raising piece 10.10.

In the figure, reference numeral 21 denotes a paper-like supply port, and 22 denotes a weight provided when the weight of the plate 7 itself is light, and this weight 22 ensures pressure contact between the drive roll 4 and the idler roll 6.

Further, 23 is a plate 7 for smoother paper feeding.
The upper surface of the oblique side 7' of the paper folding plate 11 and the oblique side 11'' of the paper folding plate 11
A machined part 24 obtained by cutting the lower surface of the slide table 1 is a support leg that supports the slide table 1 horizontally.

25 is paper for the book cover, 26, 26 is an L-shaped punch for attaching the shaft 16 attached to the plate 7, and 27° 27 is the supporting legs 24, 2.
This is a horizontal beam built on top of 4.

The aforementioned drive motor 14 is operated by a power switch (not shown), and the rotation speed of the motor 14 can be changed as appropriate.

Further, the distance t between the paper raising pieces 10, 10 is made equal to the distance between the top and bottom of the book.

Therefore, when the switch is turned on, the drive roll 4 and the idle roll 6 rotate synchronously in opposite directions, and the paper supply port 2
When the paper 25 is inserted from 1 to 1, the paper 25 is transported in the direction of the arrow in the small gap 8 by the rolls 4 and 6, and as shown in FIG. It rides on the hypotenuses 10', 10' and then enters the small gaps 9, 9, and the edges are raised almost vertically by the raising pieces 10, 10.

When the paper 25 is further transported forward, it enters the small gaps 12, 12 under the paper folding plate 11.11 and is folded 28 as shown in FIG.

When the paper 25 is further transported forward, the counter roll 4' (second
The folding line 28' is inserted between the folding lines 28' and 28'.
″′ is clearly formed.

Conventionally, in order to cover a book purchased at a bookstore with a paper bunk cover, the clerk had to manually fold the edges of the paper and cover it, resulting in the drawback that it was time-consuming to form the cover.

Since the present invention is constructed as described above, the top and bottom sides of the book can be quickly folded, and only the two sides 29° 29 (C in Figure 3) need to be folded manually, which reduces the amount of time needed to form the cover. There is a real benefit of cutting the effort in half.

By adjusting the distance t between the paper folding strips 10 and 10 in accordance with the top-to-bottom dimension of the book, both top and bottom edges of the cover can be automatically folded for books of various sizes.
