  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, three suction cups, one vacuum pump, one isolation valve, three zone branches, three pressure sensors, one contact detector and one blow-off valve. When the suction cups reach the workpiece, the suction cups are evacuated by the vacuum pump. 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.",
