  "abstract": "A suction-cup vacuum gripping tool comprising one tool-change interface, three suction cups, one ejector, one manifold and one blow-off valve. When the suction cups reach the workpiece, the suction cups are evacuated by the ejector. After the workpiece has reached the set-down position, the workpiece is blown off by the blow-off valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
