Description

FIELD OF THE INVENTION The invention relates to the printing industry, in particular to the transporter-migratory cross-weave binding.

The purpose of the invention is to improve the quality of the book block by ensuring the accuracy of combining the cover with the book block.

FIG. 1 shows the kinematic scheme. I offer my device; in fig. 2 - device, plan view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - mechanism for returning the swinging fist; in fig. 5 is a kinematic diagram of the locking mechanism for stopping the supply of the book block. .

On the shaft 1, a carriage 2 is installed with the trays 3, which can swing relative to the shaft 1. The carriage 2 receives movement from the drive; -, and 4 through the spring 5. The carrier 4 is rigidly mounted on the shaft 1. The spring 5 presses the carriage 2 to the support roller 6, set on a paired two-pE) 1 st 7, which has a swing axis fixed relative to the carrier 4, and receives movement from. fixed fist 8 through the roller 9. The additional force closure of the roller 9 to the fist 8 is carried out with the help of spring 10. On the carriage 2, there is a locking pawl 11 and an accelerating pawl 12, working in mutually opposite directions in a ratchet sectors 13, mounted on the carrier 4. The pawls 11 and 12 of the carriage fixing mechanism are pressed against sectors 13 by springs 14. A Kachyup; ice stop is mounted on the walls of the device 15. The stop 15 is compressed by spring 16 to limiter 17 of the stroke. At the end of the stop 15, a slide 18 of the acceleration control of the dog 12 is installed. The stop 15 peseta has a fist 19 on itself, paired with a sector 20 fixed on the carrier 4. The spring 21 presses the fist 19 to the latch 22 set at 23 the cable 24 is connected with the position sensor of the book block - probe 25. The spring 26 through the lever 23 and the cable 24 presses the probe 25 to the stop 27. A fixed slide 28 is installed in the path of the dog 11, there is a chain conveyor 29 for feeding the cover 30, a rocker lever 31, fist 32, lever 33 and fist 34, as well as base 35.

The device works as follows.

Valuable conveyor 29 supplies about 30 to the suction cups 3 of the carriage 2. The cover 30, fixed by the suction cups 3, is transferred to the overlap zone with the book block. At the same time, the speed of the carriage 2 is constant and equal to the speed of the carrier 4. The sequence diagram of the filing of the cover 30 and the block is constructed as

At the same time, the cover 30 approaches the zone of the combination with the book block, always earlier than the block. When the carriage 2 approaches the stop 15, the double-shouldered lever 7 from the cam 8 starts to rotate counterclockwise, gradually slowing down the carriage 2. At the moment of matching the carriage 2 with the stop 15, the absolute speed of the carriage 2 is zero. When the carriage 2 approaches the stop 15, the slide 18 retracts the accelerating pawl 12 from the teeth of the storage sector 13 and the latter, during the slowdown period and the height of the carriage 2, freely passes over the accelerating pawl 12. The spring 5 during the retardation period and the elevation of the carriage 2 is stretched. When the carriage 2 stands firmly, the roller 6 moves away from the carriage 2. The stop 15 holds the carriage 2 in place until the book block approaches the probe 25. The block, tilting the probe 25, rotates the lever 23 through the cable 24, releasing the fist 19 from the latch 22. Fist 19 under the action of the spring 21 rotates clockwise and comes into contact with a sector 20 rotating at a constant speed. Under the action of sector 20 through cam 19, stop 15 rotates counterclockwise, releasing carriage 2. Simultaneously accelerating dog 12 jumps off slide 18 and sinks into tooth of ratchet sector 13, accelerating carriage 2. After leveling the carriage 2 and drove 4 locking dog II West to the tooth of the ratchet sector 13, which is paired with it, fixes the carriage 2 in the appropriately adjusted position of the block. The carriage 2 acquires a speed equal to the speed of the carrier 4 (and the block), and is output to the gluing area of the cover to the book block. The probe 25 is so oriented relative to the stop 15 that the block, giving a signal to the carriage 2 about the beginning of movement, approaches the zone of the label at the same time as the cover 30. After the cover 30 is glued to the book block, the carriage 2 goes into the idle zone, the locking dog 11 by hill 28 is disengaged with the ratchet sector 13 and the carriage 2 under the action of the spring 5 is pulled toward the roller 6. The double-arm lever 7 rotates clockwise and the carriage 2 rotates to its original position. I shake a cims lever 31, paired with a fist 32, rigidly fixed on the shaft 1, a fist. 19 after each actuation cycle, returns to its original position and is locked with a latch 22. In the absence of a book block in the conveyor clamp 29, the lever 33, under the action of the cam 34 fixed on the shaft 1, rotates clockwise and retracts the lever 23 with the latch 22 from the cam 19 , which, entering into interaction with sector 20, turns the support 15, thus freeing the carriage 2.
