Ejecting and tray centering method

Abstract

The invention discloses an ejecting and tray centering method, and provides an embedded type ejecting and centering device on the basis of a tray chain conveying line or a roller conveying line. The centering device can be arranged at any position of the conveying line and has no interference or influences on the operation of equipment on the conveying line, and there is no need to transform the conveying line for implementation of the centering method. The method includes the following implementation steps of firstly, performing ejecting and cargo carrying, wherein an ejecting cylinder drivesan ejecting type roller assembly to ascend vertically, and a tray is ejected from the conveying line and transferred to the ejecting type roller assembly; secondly, performing centering and positioning, wherein a centering cylinder drives a group of centering frames to do linear movements from two sides to the transverse center, and the tray is centered and positioned at the transverse central line of the conveying line; and thirdly, performing descending and transferring, wherein the ejecting cylinder reversely drives the ejecting type roller assembly to descend vertically, the tray is transferred from the ejecting type roller assembly to the conveying line, and the ejecting type roller assembly falls under the conveying line and waits for a next centering and positioning process.

Description

technical field [0001] The invention relates to a method for lifting and centering a pallet conveying line without a power roller, and belongs to the field of logistics storage. Background technique [0002] In the existing e-commerce and logistics express industries, storage and sorting sites of intelligent three-dimensional warehouses, when pallets are transferred on the conveyor line, due to the following unavoidable factors, such as the deviation of the installation position of the photoelectric detection and positioning device, and the processing size of the pallet itself The error, and the lack of a needle-based guide mechanism, etc., the pallet will gradually deviate from the transverse centerline of the original conveying line, resulting in failure to meet the positioning accuracy requirements of the subsequent manipulator grabbing device, unpacking machine and stacker. The accurate docking of higher equipment will eventually lead to consequences such as missing part...

Problems solved by technology

[0004] If the centering method of increasing the guide edge and adjusting the distance between the guide edges is usually adopted in the current site, there are requirements for the length of the guide line body, and the line body that is too short cannot achieve the centering effect, and the actual guide centering effect is not ideal. It is also necessary to increase manual re-inspection and intervention, and the production cost is high
