Description

The invention relates to printing equipment and can be used in engineering for the manufacture of thin book blocks in hardcover, fastened with threads on string-stitching machines. Known store-bookholder book blocks, containing the drive blocks with the base, the mechanism of piece output blocks and drive mechanism 1.

A disadvantage of the known self-stacker shop is the unreliability of separation from the foot and the withdrawal of thin book blocks beyond the front part, which does not have a clear end edge. At high speeds of operation, such a self-locking device is voobsh, it is not operational due to the fact that the front part of the block is crushed, which leads to it being stuck in the store.

The purpose of the invention is to increase the reliability of its work.

This goal is achieved by the fact that the self-stacker of book blocks, which contain a block storage unit with a base, a piece output mechanism of the blocks and a drive mechanism, has an outlet conveyor with fingers and a vertical guide located under the base, and the base is made in the form of a L-shaped bracket one of the parts of which is placed in a vertical guide with the possibility of its height adjustment, and on the other part there are slots for the passage of fingers of the exit conveyor. The mechanism of unit output consists of a slide connected with a drive mechanism, a hinged parallelogram mounted on a slide, a pusher connected with a parallelogram, a roller mounted on one of the axes of the parallelogram, and stops, one of which is mounted on the side wall drive for interacting with the roller, and another mounted on the slide for interacting with the pusher.

FIG. 1 is a side view store; in fig. 2 shows the side separation mechanism of blocks (view A in FIG. 1). The store-bookholder of book blocks consists of a block accumulator, made in the form of a box 1, a discharge conveyor 2 with fingers 3, a base in the form of an L-shaped bracket 4 installed in a vertical guide 5 with the possibility of its height adjustment due to adjustment 6, reversible arrows 7, controlled by an electromagnet 8 and a limit switch 9 and a piece unit output mechanism, which includes a drive slider 10 installed in the guides, connected through a hinged parallelogram 11 to the pusher 12, and also replenny on one of the box walls 1 abutment 13 and the roller 14, scharnirno mounted on one of the arms of a parallelogram mechanism 11. Said

also has means 15 for adjusting its position.

Shop-bookmarker book blocks works as follows. 5 Book blocks arrive after they have been processed on a book-stitching machine along the conveyor into the drive 1 of the self-binder shop. From the accumulator, blocks one by one, from below, through the slit, are outputted by the spine. In front of the controlled fingers 3 and enter the trough of the transfer conveyor. In order to ensure that only one lower block is gripped and pulled out by the fingers, the output slit of the magazine and the protruding part of the fingers 3 is changed by changing the position of the base of the magazine in the vertical direction. During the initial filling of the accumulator, in order to avoid the first block falling into the magazine, on the moving fingers 3, the latter are deflected backward under the action of the flip

0 arrows 7 acting through the rollers 16 on the levers 17 fixed on the same shaft with the fingers 3. After the minimum number of blocks is reached in the magazine, arrow 7 is lowered, ensuring that the fingers 3 are raised in a raised relative to the magazine position. Arrow 7 is controlled by the action of an electromagnet 8. switched on by a limit switch 9 located on the wall of accumulator 1. Considering the fact that the thickness of the blocks is small, and they are removed from the magazine beyond the cutting part, which before cutting does not have a rigid end edge, reliability of output may be low. For this reason, in order to increase the reliability of gripping thin blocks with fingers 3, the store preliminarily performs lateral shearing of the lower block and lifting the edge of the foot from the side of the head, which ensures the free approach of the outgoing fingers 3 with full gripping of the lower block without gripping the block above him (Fig. 2).

Before the fingers 3 approach the drive, the slider 10 moves from the side of the head of the stitched book block having a clear end formed by the aligned notebooks heads. When the slider 10 is moved from its initial position to the right, the movement of the pusher 12 fixed to the slider 10 is located somewhat lower

0 upper edge of the lower block. The pusher 12 pushes the block through the side slot formed by the magazine wall and bottom in the direction perpendicular to the movement of the fingers 3. The block is drawn to the right by a small amount sufficient to grip with the right finger 3 of the edges of the block from the tail. At this moment, the roller 14, located on the lever of the parallelogram 11, runs into a fixed stop 13. The bar on which the pusher 12 is fixed, detaches from the stop 15, overcoming the resistance of the spring 18. As a result, the movement of the pusher 12 to the right pauses and it begins to move up, lifting stack of blocks from the side of the head. At the same time, a gap is formed between the head edge of the lower block and the foot. The movement of the slider 10 to the right is stopped. Thus, from the side of the tail, the edge of the block is completely released from the underfoot, which ensures a secure grip of the conveyor 2 with the right finger 3. The edge of the block is also released from the headstations, since the foot above it is slightly raised, which also ensures the block grip with the left finger 3. In addition, the rise

blocks of blocks by the pusher 12 prevents the next, overlying block from being caught. In turn, the lifting by the pusher edge 12 of the foot reduces the pressure on the lower unit, facilitates its withdrawal, prevents smothering and sticking.

After the output of the lower block, the slider 10 moves to the left. In this case, the pusher 12 is lowered and out of the foot. The stop is lowered and the cycle is repeated. With fingers 3, the blocks are brought into the chute of the transfer conveyor for further processing.

The high reliability and quality of the work of the proposed self-folder store allows it to be used in a production line for the manufacture of thin book blocks in hardcover.
