Abstract
A vacuum plate lifting system for lifting sheet material articles, comprises a vacuum lifter apparatus for lifting sheet material articles, a lifter actuation system configured to lift and/or move the vacuum lifter apparatus during use and a control system, the control system being configured to control the lifter actuation system during said movement. The vacuum lifter apparatus comprises: a substantially horizontal suction plate; an airflow suction system for conveying vacuum air pressure to said perforated suction lifting surface; at least one mount for connection of the suction plate to at least one actuator of the lifter actuation system for lifting and/or moving the suction plate during use. At least one elongate bar is movably mounted along an edge of the suction plate. A bar actuation system is configured to drive movement of said bar between a raised orientation and a lowered orientation.
