Intelligent storage system and its control method

Abstract

The invention discloses an intelligent storage system, comprising: a high-level four-way storage area located on the upper layer, wherein a plurality of high-level storage units are stored in the high-level four-way storage area, and the high-level four-way storage area has a storage area, The high-level storage unit can enter and exit the high-level four-way storage area through the storage area; the low-level AGV storage area located in the lower layer, wherein multiple shelves are stored in the low-level AGV storage area, and the low-level AGV storage area has complementary In the goods area, the high-position storage unit can be transported to the replenishment area to replenish one or more shelves; the four-way shuttle runs in the high-position four-way storage area to carry the high-position A storage unit; an AGV, operates in the lower AGV storage area to carry the racks.

Description

technical field [0001] The invention relates to the field of intelligent storage, in particular to an intelligent storage system including a high-level four-way storage area and a low-level AGV storage area and a control method thereof. Background technique [0002] In the warehousing system and logistics transportation links, more and more automatic guided vehicles (AGV) have been used to replace or supplement manual labor. The automatic guided vehicle can automatically receive the item handling task. Under the control of the program, it reaches the first position, gets the item, then walks to the second position, unloads the item, and continues to perform other tasks. [0003] The existing latent AGV carries the shelves to the picking workstation, so as to realize the picking operation mode of goods to people. Due to reasons such as safety and convenience of picking operations, the height of the AGV carrying shelves generally does not exceed 2.5m; therefore, for AGV wareh...

AI Technical Summary

Problems solved by technology

Due to reasons such as safety and convenience of picking operations, the height of the AGV carrying shelves generally does not exceed 2.5m; therefore, for AGV warehouses where goods are delivered to people, the space utilization rate of the warehouse is generally low

[0004] In addition, for the goods-to-person AGV warehouse, the source of goods replenishment in the AGV storage area generally needs to be transferred from other goods storage areas to the replenishment point of the AGV warehouse for replenishment, and special personnel are required to transfer the replenishment of the AGV warehouse area Operation

At the same time, it is necessary to reserve a replenishment channel in the warehouse, which wastes the available area of ​​the warehouse
