  "abstract": "A bellows-cup vacuum gripping tool comprising one mounting flange, three bellows cups, one ejector, one isolation valve, one manifold, one pressure sensor and one vent valve. When the bellows cups reach the workpiece, the bellows cups are evacuated by the ejector. Before the workpiece reaches the set-down position, the vacuum circuit is vented by the vent 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.",
