Collating mechanism

Abstract

The invention relates to a collating mechanism which comprises a stand, a power element, a transmission device, and a detection device and a control device which are arranged on the stand and a gluingtable, a paging device, a holding device and a book collecting device which are arranged on the stand in sequence; wherein the paging device comprises a front gauge and a back gauge arranged on the gluing table at correspondingly front position and rear position, a pair of side gauges arranged on the two sides of the gluing table, a paging hook, a suction nozzle, an air supply unit connected withthe suction nozzle and a paging cam, and further comprises a packing gauge arranged on the gluing table; and the packing gauge is convexly arranged on the gluing table, thus reducing the contact areabetween a bookblock and the gluing table, and simultaneously, a certain clearance is formed on the bookblock used for collating for twice. The collating mechanism is not only favorable for drawing the two bookblocks, but also for separating the two bookblocks through the paging hook, the double-sheet phenomenon is not easy to cause, and the two bookblocks are not damaged as the frictional force is reduced when paging and holding are performed on the bookblocks.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a collation mechanism. Background technique [0002] Assembling pages (assemble), also called assembling posts, is the work process of assembling book blocks or multiple loosely printed book pages into a book in the order of page numbers. Collating is generally done by a collating mechanism. [0003] The collating mechanism generally includes a frame, a power element, a transmission device, a transmission device, a detection device, a control device, a storage table, a paging device, a gripping device, and a book receiving device. [0004] The paging device is used to separate the book blocks under the storage table. The paging device generally includes a suction nozzle, a paging hook, a paging cam, and the like. The gripping device includes a gripping wheel and a gripping tooth loaded on the gripping wheel. The book receiving device includes a cardboard drop board, a guide ...

AI Technical Summary

Problems solved by technology

like figure 2 In the collation mechanism of the prior art shown, the bottom of the book drop bucket is generally flat with the bottom plate of the guide plate, and generally can only collate ordinary book blocks with a width of 135-230 mm, while for book blocks with a width of less than 135 mm Collating is more difficult

Especially for a book block with a width of 90 mm or less than 90 mm, when the book block falls into the book drop bucket, the photoelectric light switch of the detection device cannot detect the book block, and the photoelectric sensor transmits the sensing information to the control device, and the control device After receiving the induction information from the photoelectric sensor, it is considered that there is no book block state, and the control device controls the main machine to stop. The book blocks falling into the book drop bucket cannot perform subsequent operations such as book binding, so that the subsequent matching of book blocks cannot be completed. page work
