AI Technical Summary

Technical Problem

Existing storage systems cannot flexibly store goods of different sizes, resulting in low utilization efficiency of storage containers and limited processing speed of access stations, which affects the overall productivity of the system.

Method used

The system employs inventory processing station components, including access stations arranged at different levels, connected to a track system via upper and lower port columns, enabling multi-level transport and picking of storage containers. Combined with a conveyor system, this improves the visibility and processing speed of storage containers.

Benefits of technology

It improves the processing speed of storage containers and the storage efficiency of the system, reduces the need to mine storage containers, and enhances the system's flexibility and space utilization.

Abstract

A storage and retrieval system includes: A) a grid frame structure including: i) a plurality of storage columns for storing one or more storage containers in a vertical stack; ii) a track system (514) arranged above the plurality of storage columns, the track system including a plurality of tracks arranged in a grid pattern and extending in a substantially horizontal plane, and including a plurality of grid cells or grid spaces, through which storage containers in the stack can be transported between the plurality of storage columns and the top layer of the track system; B) an inventory processing station assembly (504), the inventory processing station assembly including a first layer... A) A first access station and a second access station at the second level, the first level and the second level being perpendicularly separated, so as to retrieve the contents of the storage container at the first access station and the second access station at the first level and the second access station at the second level, respectively; C) Upper port pillars (506a, 506c), the upper port pillars extending from the track system to the first access station at the first level, so as to transport the storage container between the track system and the inventory processing station assembly; D) Lower port pillars (506b, 506d), the lower port pillars extending from the track system to the second access station at the second level, so as to transport the storage container between the track system and the inventory processing station assembly.
