  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, two suction cups, one plant vacuum connection, one manifold, two zone branches, one pressure sensor and one blow-off valve. When the suction cups reach the workpiece, the suction cups are evacuated by the plant vacuum connection. Before the workpiece reaches the set-down position, the workpiece is blown off by the blow-off valve while the workpiece is above the receiving surface. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
