A stacking and unstacking device for automatic transfer of box structures

Abstract

The invention belongs to the technical field of logistics transportation mechanical equipment, and discloses a stacking and unstacking device for automatically transferring box body structures. The stacking and unstacking device comprises a portal frame unit, a claw unit and a matched whole-process monitoring and feedback unit, wherein the portal frame unit drives a claw to move in three degrees of freedom; the claw unit is able to open and close to release and grab boxed goods respectively; and the whole-process monitoring and feedback unit provides feedback functions of multiple sensors, maycomprise a top cross beam distance measuring sensor, a portal frame sensor, a claw motion sensor, a claw tension sensor, a claw contact switch and the like, and is used for monitoring the whole process of transporting goods by the claw. According to the stacking and unstacking device, complex and expensive industrial robots are not needed, the structure is compact, the design is modularized, andthe maintenance is convenient; and the efficient full-automatic stacking and unstacking can be achieved by only using some small motors and air pumps.

Description

Technical field [0001] The invention belongs to the related technical field of logistics transportation machinery and equipment, and more specifically, relates to a stacking and unstacking device for automatic transfer of a box structure. Background technique [0002] For the stacking or unstacking operations of long rectangular box goods, because the shape of the goods is biased towards the long strip, the posture of the goods is not easy to control during the conveying and turning process, so the conventional belt conveyor and roller conveyor unit are used to combine the goods. The method of piece palletizer is not applicable. [0003] At present, most of the solutions used in the industry are to use palletizing robots, which are picked up and turned over by manipulators, and stacked one by one. However, further research shows that: First, this design requires expensive industrial robots, and for goods with a long rectangular cross-section, there must be two or more gripping poi...

AI Technical Summary

Problems solved by technology

However, further research shows that: firstly, this design needs to invest in expensive industrial robots, and for goods with long rectangular cross-sections, there must be two or more gripping points to prevent tipping when grabbing; secondly , in the process of operation, if the grip strength is too high, it will easily damage the goods, and if the grip strength is too small, it will be easy to drop the package. In order to provide suitable grip strength for goods of different weights, the manipulator mechanism of robot palletizing is often complicated and cumbersome

Therefore, investing in industrial robots for automatic stacking and unstacking machines to stack and unstack long rectangular cargo stacks has a low income-to-expenditure ratio, making it difficult to promote. It is necessary to find other more economical and reasonable alternatives to automatic stacking and unstacking.
