  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, three bellows cups, one ejector, one manifold, three zone branches and one blow-off valve. When the bellows cups reach the workpiece, the bellows 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.",
