Abstract

The invention relates to bookbinding and binding equipment for life-like binding of blocks, in particular, to devices for pressing a soft cover or edging material to a book block. The invention allows to improve the quality of manufactured products by increasing its reliability. The pressure table drive contains two articulated parallelogram mechanisms 2 and 3 arranged in a vertical plane, and spatial cams 16 are used to move the compression strips mounted on the pressure table 10 and 11, which are rigidly fixed at the ends of the cranks of the parallel-parallel mechanisms. In addition, the two parallel hinge-parallelogram mechanisms 2 and 3 have adjusting means 8 and 9 of their displacement, which increase the serviceability of the device. 1 hp f-ly, 3 ill. Q cl c

7The invention relates to bookbinding and binding equipment for loose-leaf binding of book blocks, in B, in particular, to devices for pressing soft cover or edging material onto the book block.

The aim of the invention is to improve the quality of manufactured products by increasing the reliability of the device for pressing a soft cover or edging material to the book block, as well as improving the serviceability of the device.

Fig. 1 is a schematic diagram of the proposed device for pressing a soft cover or edging material onto a book block; figure 2 is a view of And figure 1; on fig.Z - view B in figure 1.

The proposed device contains a pressing table 1 with a drive, which is executed in the form of a hinge-parallelogram mechanism located in a vertical plane, which in this example of execution consists of two parallel hinge parallelograms 2 and 3, on a connecting rod, 4 of which are attached to a pressing table one.

Both parallelogram 2 and 3 are mounted on sliders 5 and 6, mounted in horizontal guides 7, JJ have adjustment means 8 and 9 for moving them along these directions

shim.

The device also contains crimping strips 10 and 11, each of which consists of a pusher 12 installed in the guides 13 of the connecting rod 4 of the corresponding hinge parallel 2 or 3 and hinged to the pusher 12 and spring-loaded sponge 15 relative to the connecting rod 4. To move each clamp bar, there are two cam pairs, the cams 16 and 17 of which are spatial and fixed on the ends of the cranks 18 and 19 of the corresponding hinge parallelogram 2 or 3, and the rollers 20 and 21 are fixed on the pusher 12.

If necessary (for moving, or jaws 15 in a vertical plane), the device can be equipped with slides 22 and 23 to interact with the projections 24 on the jaws 15. These slides are mounted on the pressing table 1.

The device works as follows.

The block 25 with a soft cover or edging material 26 glued to the spine is driven at a constant speed with the transport mechanism clamps to the pressing position. Rotating, the hinge parallelograms 2 and 3 lift the presser table 1 and crimp strips 10 and 11 to the spine of the block. In this case, the rollers 20 and 21 of the crimp strips 1 O and 11 make a clean cut around the spatial cams 16 and 17.

When the pressing table 1 approaches together with the crimping strips 10 and 1 1 to the spine of the block 25, the spatial cams 16 and 17, acting on the rollers 20 and 21, move the crimping strips 10 and 11 in the horizontal direction and at the moment when cranks 18 and 19 hinge parallelograms occupy the upper vertical position; the cover or edging material is pressed to the spine of the book block.

Crimping jaws 15 can be raised by a small amount, turning around their: hinges, bumping on slides 22 and 23. of the pressure table 1 and pulling a soft cover on the relative back side.

F o rm u la invention

A device for pressing a soft cover or edging material onto a book block, containing a powered press table, 1 compression strips, each of which is mounted on the table and has a mechanism for its translational movement in a horizon-tal plane, including a cam pair, characterized by that, in order to improve the quality of manufactured products by increasing the reliability of its work, the drive of the pressure table is designed as located in a vertical plane. two hinge-parallelogram mechanisms, and each displacement mechanism of the corresponding crimp bar has an additional cam pair, the cams of these pairs are made spatial and rigidly fixed at the ends of the cranks of the hinge-parallelogram mechanisms.
