Patent ID: 7930902

Claim:
A mechanism for conveying an article comprising a first servo operated member, a first servo motor for operating said first servo operated member in accordance with a cam profile, said cam profile having a plurality of continuous Bezier curve segments each defined by Bezier curve segment inputs, wherein the first servo operated member further comprises a second servo operated member, a second servo motor for operating said second servo operated member in accordance with a second cam profile, said second cam profile having a plurality of continuous Bezier curve segments each defined by Bezier curve segment inputs, an operator data entry device for entering at least one physically observable structure related performance variable having a predetermined range, wherein said at least one physically observable structure related performance variable is one of arm retract speed, finger angle at release, percent of time capturing bottles, jack knife time, and belt advance factor, and a control configured as a mapping device for receiving said performance variable and determining, for the received performance variable, Bezier curve segment inputs, and a segment generator for receiving said Bezier curve segment inputs and for computing intermediate segment points for at least one of the Bezier curve segments, wherein the mechanism is a pusher mechanism for pushing bottles formed in an I.S. machine through an angle of about 90 degrees from a dead plate onto a moving conveyor, the pusher mechanism including an arm member rotatable about a first axis and a finger member, rotatable about a second axis, spaced apart from said first axis, and supported by said arm member, and wherein the first servo operated member is the arm of the pusher mechanism, and wherein the second servo operated member comprises said finger member.
