Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cover press device for a bookbinding machine.

This device is located on the side clamping rails and on the plate that presses against the book spine, these rails and plates being arranged in a horizontal direction, if necessary, in order to effect the pressing movement of the cover against the block. Alternatively, it is possible to move synchronously with a vertically moving block transport system.

[Conventional technology]

When a book is bound with an adhesive hand, the cover is firmly glued to the book flock which is not yet glued by means of a cover press device. The cover, which has previously been placed in line, or often in a facing line, is then pressed against the spine of the block and in adjacent areas on the same side. On the other hand, the movement of the blocks occurs continuously without interfering with each other. It is of particular importance that, in the operation in which the covers are attached and pressed, it is consistent with the fact that the shape of the spine of an unbound book receives a pleasant sharp edge, which makes the final result of this operation favorable. It is to be. It is already known to apply a lateral compression force and a compression force from below simultaneously by means of press plates communicating with side clamping rails towards the spine of the book. A device with two tools that can move synchronously with a block transport system over a straight line and a defined travel distance is needed.

Details of this type of cover press device are just described, for example, in Swiss Patent No. 626,833.

[Problem that the invention seeks to solve]

It is already known that in practical experience, compressive action of the tool or uncontrolled moments occur, in which case it is displaced from the required position relative to the cover or the predetermined spine of the block. Occurs when This occurs especially when the block exhibits a mushroom shape and its spine is wider than the distance between the curved lines of the predetermined border. In such cases, the mushroom shape exhibits an asymmetric shape, resulting in extremely poor alignment of the cover with respect to the spine of the block. If the flock spine is incorrectly centered, the result is either grooves in the cover or bent lines, which always leads to a reduction in product quality. This simple defect in the spine of a book can cause the book's title to stick out at an angle to the spine, creases, and various other problems.

[Means to solve problems]

The object of the present invention is to improve the quality of the general format by ensuring that the book flock is properly aligned against the spine of the block by preventing displacement during the pressing process. The purpose is to improve the cover press device. The purpose of this is that the side clamping rails with suction or gripping means are raised as soon as the press is carried out against the back of the flock, and that the horizontal movement of the side clamping rails Coordinated with the vertical movement of the plate pressing against the back, the side clamping rails perform a compensated movement relative to the block in the manner described above, and at the same time the plate performs a pressing movement perpendicular to the back of the block. This can be achieved by doing the following.

Embodiments of the load-bearing mouth are characterized in the dependent claims.

The invention of this pressing device is based on the fact that while the flock is placed and pressed, the cover is supported in a position in line with the back of the flock and never changes from that position. 1) It is possible to properly label a block with a title. Even in the case of a one-piece cover with a curved one-line wire, there is either a pre-determined line so that the back of the flock lies exactly one point on this gland.
・If these centers are aligned, it is guaranteed. The cover remains centered at all times. Then, even if you choose only one flock, you will not be able to exert any effect of the exact action of the kenonok.

〔Example〕

The cover press device consists essentially of a plate 3 which presses against the dorsal side and side pay rails 4 and 5 which are above the press plate 3 and movable laterally towards the lateral face of the block. is formed by. As is well known, this plate 3, which performs a press against the back, undergoes a vertical and horizontal movement over a defined travel distance by a subsequent movement carried out simultaneously with the conveying system. As a result, the block clamping device 2 moves horizontally inward at the same time as the side clamping rails 4 and 5.

The plate 3 that presses against the back is moved by rollers 7 and 8.
It is supported by a lateral carriage 9 which is movable inwardly by means of a guide cradle 6 having .

For this purpose, a pull lever 10 on the carriage 9 of one part of the actuating arm 11, acting by a desk cam mechanism not shown, acts, causing the transverse carriage 9 to perform a linear movement. Become. The same desk cam mechanism also influences the vertical movement of the guide cradle 6 via the control arms 12 and 13 acting at its end; the movement of this actuator is not the subject of the present invention and will therefore be described no further here. Avoid explaining.

The mounting rods 17 and 17a are arranged on the transverse carriage 9 on which they are held, which is connected to the side pieces 15 and 15a forming a support frame. Support 1 attached to rods 17 and 17a
6 and 16a have the function of supporting the tightening rails 4 and 5, and are allowed to freely slide relative to these rotors 1 to 1. The two side pieces supported by guide rods 18 and 18a] 5 and 15a are supported by supports 16 and 16
a and are fixed in such a way that they cannot move relative to each of the clamping levers 4 and 5 (G). Supports 16 for guide rods 18 and 18a and clamping rails 4 and 5
and 1.6a are side clamping rails 4 and 5 that can slide freely in the axial direction of the carriage 9 and exert a pressing force on the 11111 faces of the blocks in the side pieces 15 and 15a. and compression springs 1w24 and 24a1 located on opposite sides of the rail, supported by these compression springs or links 19 and 19a, are supported toward the carriage 9. 0 The control of the opening and closing movement of the clamping rail is exercised parallel to the horizontal movement of the carrier 9 in the guide frame 6 and
Guide rods 18 and 18a positioned by cam tracks 26 and 26a located above are carried out via fixed cam rollers 25 and 25a.

According to the invention, each of the side clamping rails 4 and 5 has a row of holes 4 which can be drawn in by suction air.
a and 5a are provided, and the functions of these holes 4a and 5a are as follows.
Exactly in line with the back of Flock 1, kite 31 on the side
and 31a support the cover 18, thereby fixing it in a predetermined position relative to the back of the proc until it is momentarily raised for pressing.

A correction flap 32 is used to achieve precise alignment of the feed, which flap 32 is rotatably mounted on the carrier 9 and corrects the cover 13. Regarding block 1, it belongs to the cam roller 32 that is fed once
a rotates towards the cam piece 33 belonging to the guide frame 6 with the aid of a spring element (not shown). but,
At this time, the cam roller 32a maintains contact with the cam piece 33.

As mentioned at the outset, the backward pressing plate 3 carries out a horizontal movement over the travel distance and acts synchronously with the clamping device 2 holding the floes of the transport system,
And during this synchronous movement, a vertical movement is carried out against the back of the flock with the purpose of firmly adhering the cover. This continuous movement is carried out by a cover press device held in the clamps of the transport system and acting simultaneously on a number of successively passing floes.

When the side clamping rails 4 and 5 acting at the same time are at rest and the cover requires correction, the position of the flock relative to the back is fixed at the position before the vertical movement of the plate 3 that presses against the back; Make sure the adhesive coat on the back of the flock is against the cover. During the vertical stroke in which the block advances to press the cover into the space formed by the side clamping rails 4 and 5 and the plate 3, a compensating movement of the side clamping rails is necessary.

In the course of these movements the cover is fitted snugly around the spine of the block. As a result of further pushing, the spine of the block is accurately positioned and pressed within the area of the spine of the cover by predetermined marks. [Effects of the Invention] According to the present invention, the pressing device presses the spine of the block. On the other hand, the fixation of covers placed in the same row was ensured, and as a result, it became possible to paste the covers to the spines of the blocks with accurate markings. The mushrooming that is unavoidable during the production of blocks, and also the asymmetry that often occurs, do not have any influence on the accuracy of the working of the casing. Once the centering has been effected and pressure has been applied to the back, the inlets 4a and 58 of the side clamps 4 and 5 are closed and the cover can move upwards without any hindrance. During this time, the work is inevitably completed under pressure from the sides.
