Abstract

This article describes a material handling system for an automatic warehouse. The system includes an upper or mezzanine floor where ordered parts are picked and stacked. An automatic storage and retrieval system transports material from pallet racks to the picking station on the mezzanine f loor. Ordered material is transferred by a crane system to a lower floor where an automatic guided vehicle system (AGVS) performs the part distribution function. This system can also be applied to issue full pallets of material by delivering directly to the lower level output spur by bypassing the pick loop on the mezzanine floor.

Automatic Material Handling System

This article describes a material handling system for an automatic warehouse. The system includes an upper or mezzanine floor where ordered parts are picked and stacked. An automatic storage and retrieval system transports material from pallet racks to the picking station on the mezzanine f loor. Ordered material is transferred by a crane system to a lower floor where an automatic guided vehicle system (AGVS) performs the part distribution function. This system can also be applied to issue full pallets of material by delivering directly to the lower level output spur by bypassing the pick loop on the mezzanine floor.

With reference to the drawing, the material handling system comprises a combination of three systems, namely: (1) an automated storage/retrieval system (AS/RS), (2) an input/output system for the AS/RS, and (3) a series of order-filling/parts-picking stations. The order filling/parts-picking stations are associated with a mezzanine floor 10, while the input/output system for the AS/RS is associated with the lower floor 12.

The AS/RS is a conventional system utilizing conventional methods to move pallet loads of material to and from locations in an aisle of the pallet rack structure. The system contains one or less AS/RS machine (per aisle). If less than one machine is provided per aisle, each machine services multiple aisles by transferring from aisle to aisle on a transfer car.

The input/output system is an AGVS or conveyor system with input and output spurs at one end of the rack aisle. This is located on the ground or primary access level of the AS/RS.

The order-filling/parts-picking stations are located at the end of each aisle on the mezzanine at one or more upper levels. These consist of an AS/RS output spur and queue 20, an AS/RS input spur and queue 21, a "pick from" pallet location 22 and a "pick to" pallet location 23. These are arranged with appropriate transfer hardware to allow:
a) Transfer of pallets from the AS/RS output spur 20 to the "pick

from" pallet location...
