  "abstract": "A bellows-cup vacuum gripping tool comprising one tool-change interface, one bellows cup, one ejector and one blow-off valve. When the bellows cup reaches the workpiece, the bellows cup is 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.",
