Description

Technical Field

[0001] The invention belongs to the technical field of book stacking and palletizing, and in particular relates to a stacking and palletizing device for unloading books. Background Art

[0002] During and after the processing, the books need to be stacked for storage and transport to the next processing mechanism;

[0003] The stacking mechanism for book unloading described in the patent application with reference publication number CN116853833A comprises an unloading conveying mechanism and a stacking robot, wherein the stacking robot is provided with an unloading fixture, wherein the unloading fixture comprises a clamping block which can be opened and closed, wherein the clamping block is provided with a book pressing member and a supporting member, wherein the book pressing member elastically presses the book, and the supporting member can be flipped to support the book and provide the book for unloading; after the book is conveyed to a designated position by the unloading conveying mechanism, the unloading fixture moves to be aligned with the book, the unloading fixture descends to clamp the book, the book pressing member presses down against the top of the book, and then the supporting member flips to support the book, so that the book is clamped up and down by the book pressing member and the supporting member, and then after the unloading fixture moves to the designated position, the supporting member flips to provide the book for unloading from between the two clamping blocks; there is no need for the clamping block to clamp the book, and friction can be reduced during unloading, thereby effectively protecting the book, and the clamping is more stable, and the book will not fall.

[0004] After the books are processed, they are easily squeezed and scratched during the transfer and stacking process, as well as during unstacking.

In addition, after long-term stacking, new books will stick to each other, and the books will fold during unstacking, which will affect the appearance of the books and even affect their sales.

[0062] In this embodiment, by setting the inner sliding transfer assembly 7, in use, the stacking isolation seat 802 is inserted on the roller 706 along the positioning groove, and the rotating feeding motor 704 is started and controlled to select and adjust the direction of the stacking isolation seat 802 to store books. After the plastic-wrapped books are fed into the stacking isolation seat 802 along the rear conveying assembly 4, the driving motor in the driving mechanism 702 is started to slide the transfer assembly 8 outward along the inner slide rail seat 703, and cooperate with the pick-and-place assembly 6 to move the stacking isolation seat 802 and the stacking isolation seat 802. The books are moved to the outer sliding transfer assembly 8, which reduces manual participation and improves the efficiency of transfer and stacking. When the books are placed in the stacking isolation seat 802, the gravity and friction resistance increase. The arrangement between the plurality of rollers 706 and the stacking isolation seat 802 reduces the friction resistance between the feed tray 705 and the stacking isolation seat 802, thereby facilitating the movement of the stacking isolation seat 802. The arrangement of the lifting and feeding hydraulic cylinder 701 can realize the lifting and adjusting of the height of the stacking isolation seat 802, so as to achieve the purpose of stacking and stacking the stacking isolation seat 802 on the outer sliding transfer assembly 8.

[0063] In this embodiment, the outer sliding transfer assembly 8 is set up and used in conjunction with the pick-and-place assembly 6 and the inner sliding transfer assembly 7; the height of the stacking isolation seat 802 and the electric suction cup 603 on the feeding tray 705 is lifted and adjusted by controlling the lifting and feeding hydraulic cylinder 701 and the third lifting hydraulic cylinder 601 in the middle, so that the two are flush, and the stacking isolation seat 802 on the feeding tray 705 is at the top of the stacking seat or the topmost stacking isolation seat 802 in the stacking seat, and the electric suction cup 603 is moved by controlling the pulling hydraulic cylinder 602. When the electric suction cup 603 is attached to the outer wall of the stacking isolation seat 802 on the feeding tray 705, the electric suction cup is opened. The plate 603 is adsorbed, and then the electric suction cup 603 is controlled to absorb the stacking isolation seat 802 on the feeding plate 705 and move it above the stacking seat for stacking. The setting of the anti-slip pattern 803 can increase the friction resistance between the inner wall of the stacking isolation seat 802 and the heat shrink film wrapped around the outer wall of the book, thereby achieving a better anti-slip effect. The setting of the stacking isolation seat 802 can achieve the protection and isolation effect of the outer wall of the book, and avoid the situation where the ink on the paper sticks due to the greater pressure on the bottom of the book after the books are directly stacked in a high number of layers. After stacking several stacking isolation seats 802, it is also convenient for users to split and take books.
