Abstract

An automated system for storing and retrieving objects from multiple object categories. A plurality of storage rack assemblies is included. Each storage rack assembly has a plurality of slots sized for storing objects. A storage transport is movable alongside each respective storage rack assembly for positioning adjacent any slot. A plurality of horizontal tracks are arranged to be perpendicular to the storage rack assemblies. Each storage rack assembly has an end adjacent the tracks. A runner transport is coupled to and movable on each track for receiving one of the objects from, or providing one of the objects to a storage transport. Two conveyor rack assemblies are located at opposite ends of the tracks, aligned perpendicularly to the track. Conveyor transports are adjacent the conveyor rack assemblies for transferring objects between the conveyor rack assembly and the runner transports. Storage and retrieval operation requests are generated by simultaneously providing positioning signals to a conveyor transport, a runner transport and a storage transport. Storage transports are selected in accordance with a predetermined transport selection function. Storage slots are selected in accordance with a predetermined slot selection function. A database stores the category, age and location of each of the objects.
