Abstract
Abstract An automated work center for use in materials handling operations is disclosed. The work center includes a randomly accessible vertically moving temporary storage queue 11 for receiving containers 25 that hold material goods. A fixed loading ramp 20 is arranged to receive containers 20 from an external system and to load the received containers onto the storage queue 11. A work area 5 having a plurality of rotatable work tables 7 provides an gives the operator access to the containers. A delivery system 14 transfers containers between the storage queue 11 and the work tables 7 and a takeaway system 16 transfers containers between the work area and the conveyor network. An automated control system 17 coordinates the delivery of containers between the temporary storage queue 11 and the work area 5. A consolidation queue 18 having a multiplicity of vertically spaced shelves may be disposed opposite the work tables 7 to facilitate the consolidation of ordered goods.
