Abstract
Abstract This is a storage system having a stacker which may be operated in remote full automatic control or in manually permitted automatic control from the cab on the stacker. The stacker has a pivotal overhead shield to protect the person operating the stacker manually. In the raised position a limit switch is closed which permits stacker moves only when the order picker is on board and holding closed two foot switches and two hand switches. Shuttle operation is restricted to specific off load points for removal of picked loads. The overhead shield when folded down permits full automatic operation with maximum vertical travel of the stacker and when in the upright position provides means under control of the operator to permit automatic operation of the stacker and protects the operator on the stacker from overhead falling objects.

Claim 1
Independent Claim
344 words
A storage system for material units comprising: a storage structure with multiple bins arranged in rows and columns and defining an aisle adjacent said bins, each of said bins being adapted to receive a material unit, a load station at the end of said aisle in alignment with the row of bins, a stacker vehicle adapted to move forward and backward in said aisle between the load station and a selected bin, and between selected bins, said stacker vehicle including a material platform adapted to support a material unit and to move laterally of said aisle to transfer a material unit to and from a selected bin, said stacker vehicle including driving means for moving it along said aisle and for actuating of said platform, said stacker selectively operated in full automatic control or under manually permitted automatic control, an operator mounted platform on said stacker capable of supporting an operator, a shield pivotally attached to said operator platform, said shield so constructed that when pivoted to its upright position a portion thereof is located over the head of an operator when said operator is standing on said operator platform, said shield so constructed that when pivoted to its lower position it restricts an operator from occupying said operator platform, a first switching means capable of energizing said stacker for automatic operation, a second switching means capable of energizing said stacker for manually permitted automatic control by an operator from saiD operator platform, means for automatically actuating said first switching means when said shield is in its lowered position to permit automatic operation of said stacker, means for automatically actuating said second switching means when said shield is pivoted to its upper position to permit automatic operation of said stacker by manual control from an operator from said operator platform, whereby the stacker is under the control of an operator from said platform when said shield is in the upright position, and an operator is restricted from said platform and the stacker is under automatic control when said shield is in its lowered position.
