Product storage and retrieval
An inventory system for storing and locating goods in a storage area. Ordered goods are placed in bag units at a central filling center. The filled bag units are shipped to local storage areas where they are placed onto rails in a storage structure. The rails include an imaging sensor at each bag receiving location defined on the rails for obtaining a bag identifier that is affixed with the bag unit. The bag identifier and the rail address for each bag unit is stored on a local computer database. When a user wants to pick up stored goods, the user inputs the identification or order information for the goods and the computer will search the inventory to locate the goods in a specific stored bag unit. The rail adjacent the bag unit will be illuminated to facilitate locating the goods.
1. An apparatus for product storage and retrieval, comprising:
a rail having a length and a plurality of bag receiving locations defined along the length of the rail;
a plurality of imaging sensors, each imaging sensor positioned adjacent a respective one of the plurality of bag receiving locations and configured to detect a bag unit placed at the respective one of the bag receiving locations on the rail and to obtain a corresponding bag identifier from a scan of the placed bag unit;
an electronic circuit affixed with the rail and coupled to each of the plurality of imaging sensors and to a controller;
a local processor in the electronic circuit having a memory for storing bag receiving locations and bag identifiers for detected bag units, and configured to communicate between the electronic circuit and the controller; and
the controller configured to query the local processor with a first bag identifier, and if the first bag identifier matches one of the corresponding bag identifiers stored in memory for a detected bag unit, then return the respective bag receiving location.
2. The apparatus of claim 1 , further comprising:
the rail includes a rail identifier, and each bag receiving location is identified by a digital address that includes the rail identifier and the corresponding bag receiving location.
3. The apparatus of claim 1 , further comprising:
the rail comprises a plurality of sections each having a plurality of bag receiving locations defined along the section, each section having a unique rail identifier, and an electronic circuit for each section.
4. The apparatus of claim 1 , further comprising:
the bag receiving location includes a receptacle formed in the rail and adapted to receive a bag unit.
5. The apparatus of claim 1 , further comprising:
the bag receiving location includes a post extending from the rail and adapted to receive a bag unit.
6. The apparatus of claim 1 , further comprising:
a plurality of the rails affixed in a structure, each rail comprises a plurality of sections each having a plurality of bag receiving locations defined along the section, each section having a unique rail identifier, and an electronic circuit for each section.
