  "abstract": "A bellows-cup vacuum gripping tool comprising one mounting flange, one bellows cup, one plant vacuum connection, one pressure sensor, one contact detector and one blow-off valve. When the bellows cup reaches the workpiece, the bellows cup is 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.",
