Description

Technical Field

[0001] The present application relates to the field of booklet packaging devices, and in particular to a booklet stacking device. Background Art

[0002] The book stacker is used to stack books that have been glued and stapled together and are running individually on the conveyor line. It can be connected to the conveyor line to transport the stacked books to the three-sided knife or other equipment. It can also be used to stack books into piles for collection, reducing the workload of manual book collection and stacking and improving work efficiency.

[0003] For example, the patent with the patent authorization announcement number CN217598183U discloses an automatic book stacking mechanism, but it still has the following shortcomings in actual use:

[0004] When the books are stacked in a pile, they fall onto the rotating table. The second bookstops arranged on both sides of the rotating table align the two sides of the stack of books that fall onto the rotating table. Then, the book-beating cylinders arranged on both sides of the book-beating plates drive the book-beating plates to align the front and back of the books that fall onto the rotating table. However, the sizes of books vary. When the books to be stacked are too small, the length of the books is much smaller than the length of the second bookstops. When the books are clamped by the second bookstops, the book-beating plates arranged at both ends of the second bookstops may not be able to beat the front and back of the books, and thus the front and back of the books cannot be aligned, resulting in uneven stacking of the books. Utility Model Content

[0005] In order to improve the problem that books that are too small cannot be aligned front to back, resulting in uneven stacking of books, the present application provides a book stacking device.

[0016] By adopting the above technical solution, the connecting rod can convert the linear motion of one crossbar into the rotational motion of the rotating rod, and then convert the rotational motion of the rotating rod into the linear motion of the other crossbar, thereby realizing the synchronous sliding of the two crossbars.

[0017] Preferably, an electric push rod 1 is fixedly provided on the rear side of the bottom of the tray via a mounting frame, and the output shaft of the electric push rod 1 is fixedly connected to one end on the inner side of one of its cross bars.

When the books are stacked to a preset number, the first-layer book receiving cylinder and the second-layer book receiving cylinder are activated at the same time. The first-layer book receiving cylinder drives the first-layer book receiving plate to retract, and the second-layer book receiving cylinder drives the second-layer book receiving plate to open, so that the books stacked in one pile fall into the second-layer stacking device. Then the second-layer book receiving cylinder is activated to drive the second-layer book receiving plate to retract, so that the books stacked in one pile fall onto the tray 4. By setting up two stacking devices, the efficiency of book stacking is improved.
