Abstract

A warehousing system and apparatus for retrieving articles from a preselected storage area containing a quantity of the same and delivering them to a designated area spaced therefrom. A track extends a selected distance along a predetermined path that is offset a selected distance from the stored articles. A motorized carriage is rollingly mounted on the track and has a load carrying support surface thereon on which a payload is accumulated one article after another during the building of such load. A rigid superstructure is carried by the carriage and an extendible and retractable reach is mounted on thereon. A power operated article gripping assembly is carried by the reach for grasping articles one at a time in the storage area and loading them in sequence onto the carriage for delivery to the designated area. The apparatus is controlled from a location spaced from the storage area and inter-relates and controls movement of the carriage along said track, extension and retraction of the reach, and operation of the article gripping assembly to retrieve articles.
