Abstract

In automatic warehousing systems, it is desired to make a picker mechanism which selectively stores and fetches articles with respect to a fully automatic storage compartment, eliminating controls and control lines between the picker mechanism and the controlling system. When an article is to be stored, the mechanism should automatically release the article in the appropriate location within a storage compartment. On the other hand, when an article is to be fetched, the picker mechanisms should enter the storage compartment, automatically secure the article to the picker, and remove it from the storage compartment for transport to another location.

Article Handling

In automatic warehousing systems, it is desired to make a picker mechanism which selectively stores and fetches articles with respect to a fully automatic storage compartment, eliminating controls and control lines between the picker mechanism and the controlling system. When an article is to be stored, the mechanism should automatically release the article in the appropriate location within a storage compartment. On the other hand, when an article is to be fetched, the picker mechanisms should enter the storage compartment, automatically secure the article to the picker, and remove it from the storage compartment for transport to another location.

An article carrier includes a carriage having article gripping arm 10 reciprocating between article carrying position 11 and load/unload position 12. In position 11, the article being conveyed is in the article carrier clear of the storage compartment wall, enabling carrier movement along the storage compartment array. Assume a store cycle is being executed. Arm 10 is moved to the left, carrying the article into the storage compartment. As arm 10 is moved to the left, inserting the article into the storage compartment, pawl 14 engages the lower end of unloader 15. As arm 10 continues its motion, pawl 14 pushes unloader 15 against its stop. This action rotates spring-loaded pawl away from its stop on arm 10, forcing arm 10 to pivot counterclockwise as shown by arrow 16. Article handling end 17 of arm 10 begins to pivot upwardly, but continues to push the article into the storage compartment against the pushing edge 18. The arrangement is such that when the artic...
