PLC-based stereo warehouse cyclic delivery method

Abstract

The invention belongs to the technical field of a stereo warehouse transfer line and specifically relates to a PLC-based stereo warehouse cyclic delivery method, for solving the technical problem of providing a PLC-based stereo warehouse cyclic delivery method advantaged in quite high reliability. The employed technical scheme is as follows: the PLC-based stereo warehouse cyclic delivery method comprises the following steps: performing station division on stereo warehouse cycle line; receiving a goods warehousing request, and placing goods on an initial station; determining whether an inlet station and a next station of the inlet station are zero-loaded at standby states; pushing the goods to the inlet station, and pushing the goods forward along the cyclic direction of the cycle line; determining whether a tunnel replenishment port station is zero-loaded at a standby state; and pushing the goods to the tunnel replenishment port station and pushing the goods into a tunnel along the cyclic direction of the cycle line. The method is applied to the technical field of a stereo warehouse.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional warehouse conveying lines, and in particular relates to a PLC-based three-dimensional warehouse circulation conveying method. Background technique [0002] In today's ever-changing development of science and technology, and in the face of increasingly fierce social competition, three-dimensional warehouses are undoubtedly the best way for the logistics and warehousing industry to solve storage space, save manpower and improve efficiency. [0003] According to the traditional method, if the storage stations on the circulation line are full, the goods on the circulation line cannot enter because there are goods on the conveyor at the entrance of the roadway, and they will wait at the original position. , the channel is often blocked, so that either the storage affects the storage, or the storage affects the storage, or it may be that a lane failure affects the entire system and cannot proc...

Problems solved by technology

[0003] According to the traditional method, if the storage stations on the circulation line are full, the goods on the circulation line cannot enter because there are goods on the conveyor at the entrance of the roadway, and they will wait at the original position. , the channel is often blocked, so that either the storage affects the storage, or the storage affects the storage, or there may be a failure in a lane that affects the entire system and cannot be carried out smoothly.

According to the original technology, the circulation line can be freely programmed, and the access conditions are simple, so that it can be entered when it is free. Even if the circulation line flows normally, it may cause the circulation line to be blocked when the volume of inbound and outbound storage reaches a certain value. At this time, the entire system will be blocked. be paralyzed, unable to move
