Abstract

This apparatus provides a mobile machine system which functions under (previously prepared) tape or punched card control to retrieve merchandise from magazine or gravity storage rack storage to fill orders. The entire mechanism is mounted on a mobile base 1, capable of moving along an aisle, or any other pre-established path, following the guidance of an overhead truck-trolley 2 from which both power and steering guidance are taken. Program for operation of the vehicle is pre-established by key punching, computer, a tape or a punched control file, placed within the unit for directing its retrieval, sortation, and dispatch of merchandise orders.

Order Filling From Magazine Loaded or Gravity Storage Rack Merchandise Storage

This apparatus provides a mobile machine system which functions under (previously prepared) tape or punched card control to retrieve merchandise from magazine or gravity storage rack storage to fill orders. The entire mechanism is mounted on a mobile base 1, capable of moving along an aisle, or any other pre- established path, following the guidance of an overhead truck-trolley 2 from which both power and steering guidance are taken. Program for operation of the vehicle is pre-established by key punching, computer, a tape or a punched control file, placed within the unit for directing its retrieval, sortation, and dispatch of merchandise orders.

As the unit moves along the path directed by the overhead rail, position location is obtained magnetically, optically, or mechanically, from position location indexes on the overhead rail. These locations are transmitted electrically to a logic unit within the vehicle control system, and matched with the next instruction location in the tape or punched card instruction unit. When the comparator indicates that an instruction position has been obtained, that instruction in the program file is converted to the signal necessary to activate the appropriate mechanical action. Such instructions may be to "start moving", or "Transfer to an accumulator shelf number-". When the instruction is to "pick an item and transfer to shelf number-", the logic switches on the mechanism under the vehicle which then moves out from the opening provided, pulls a box 7 or container out of the storage magazine adjacent to that position, pulls it into the machine, and transfers it to the elevator mechanism. Upon retraction of the retrieval arm 3, and transfer of the box 7 to the elevator arm 4, the latter is raised by chain or piston to the heart of the shelf upon which that item is to be accumulated. Upon arrival at the proper accumulator shelf 5, an ejector bar 6 moves forward under piston or cam act...
