Abstract:
1. A workpiece container storage and handling system, comprising: a base; a number of wheels connected to the base to provide for movement of the base; and a container handling system connected to the base, the container handling system including at least two separate container transfer mechanisms collectively defined to hold at least two containers in a vertically overlying orientation relative to each other, vertically adjacent ones of the at least two separate container transfer mechanisms separated by a fixed distance measured in a vertical direction, the container handling system including a vertical travel mechanism, each of the at least two separate container transfer mechanisms connected to the vertical travel mechanism such that movement of the vertical travel mechanism in a vertical direction causes corresponding movement of the at least two separate container transfer mechanisms in unison in the vertical direction so as to maintain the fixed distance separation between the vertically adjacent ones of the at least two separate container transfer mechanisms, each of the at least two separate container transfer mechanisms including a horizontal travel mechanism configured to provide for controlled and independent horizontal travel of a corresponding one of the at least two containers relative to the base.
