ABSTRACT:
An apparatus for providing an automated device for removing horizontal members such as lid members from a vertical stack thereof one at a time for processing such as refurbishing, cleaning or sanitizing thereof. A carriage assembly is movably guided by a carriage guide plate between a pick-up position adjacent a lid stack for movement thereof one at a time to a releasing position for refurbishing. The carriage assembly includes a carriage frame defining a vacuum chamber therein connected through fluid flow communication to a source of vacuum and a source of high pressure blowback air. Pick-up outlets are defined in the carriage frame and include vacuum cups thereon to facilitate applying suction adjacent to a single lid for lifting thereof by the carriage assembly and movement from the pick-up position to the releasing position. A stack securement device is also provided for clamping the remaining portion of the stack as a single lid is removed from the top of the stack by vacuum.
