  "abstract": "A bellows-cup vacuum gripping tool comprising one tool-change interface, six bellows cups, one plant vacuum connection, 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 plant vacuum connection. After the workpiece has reached the set-down position, the vacuum circuit is vented by the vent valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
