Abstract

An information storage and retrieval apparatus employing traveling elevators for selectively transferring information containing articles from an array of storage compartments to one of a plurality of transfer ports, for moving the article to an article processing station, can be enhanced by selectively leaving unoccupied storage compartments throughout the array. By using the described technique, practically every traveling elevator movement carries an article, thereby reducing total elevator movement.

Article Storage

An information storage and retrieval apparatus employing traveling elevators for selectively transferring information containing articles from an array of storage compartments to one of a plurality of transfer ports, for moving the article to an article processing station, can be enhanced by selectively leaving unoccupied storage compartments throughout the array. By using the described technique, practically every traveling elevator movement carries an article, thereby reducing total elevator movement.

As shown in the drawing, the cross-hatched storage compartments are left empty for enhancing total system performance. Transfer ports 10 are spaced among the storage compartments in accordance with the design of the article processing station. The traveling elevator, not shown, selectively accesses an article in one of the storage compartments and transfers the article to one of the transfer ports 10. Immediately thereafter, it must access another article or store an article from an adjacent transfer port. For example, a first article may be inserted into port 10A. Adjacent port 10B may have an article to be stored. The article from port 10B may have been originally acquired from storage compartment 11C. However, empty storage compartment 12B is closer to port 10B than is storage compartment 11C. Hence, the article from 10B will be stored in compartment 12B, leaving compartment 11C unassigned, i.e., an empty port.

At this time, a second article may...
