  "abstract": "A suction-cup vacuum gripping tool comprising one mounting flange, four suction cups, one ejector, one manifold, one pressure sensor, one contact detector and one blow-off valve. When the suction cups reach the workpiece, the suction cups are evacuated by the ejector. 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.",
