Claim 5:
6. A vacuum cup assembly of a material handling system, the vacuum cup assembly comprising:
a vacuum device body adapted to connect to a pressurized air supply, the vacuum device body including a venting element;
a venturi nozzle housed in the vacuum device body;
a piston element housed in the vacuum device body, the piston element including a desired shape including an edge perimeter margin portion, defining a peripheral border of the desired shape, the piston element coupled with a sealing element, the piston element having a sealing position and a venting position;
a biasing element biasing the piston element toward the venting position;
a vacuum cup in fluid communication with the vacuum device body, the vacuum cup configured to engage an object; and
when the pressurized air supply is activated, the pressurized air moves the piston element to the sealing position wherein the sealing element coupled with the piston element perimeter edge margin portion, engage closing fluid communication between the vacuum cup and the venting element and, in turn, closing the venting element and the venturi nozzle generates a vacuum so that the vacuum cup substantially seals against the object, and when the piston element is in the venting position fluid communication is open between the vacuum cup and the venting element and the venting element is operable to substantially vent the vacuum, the vacuum cup can disengage from the object.
