  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, two bellows cups, one ejector, two isolation valves, two zone branches, two pressure sensors and one vent 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 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.",
