Transfer apparatus for transferring a workpiece from a moving anvil to a moving carrier
First Claim
1. A transfer apparatus for transferring a workpiece from a first location to a second location comprising:
- a support structure comprising a support member rotatable about a first axis; and
a first drive motor for effecting rotation of said support member about said first axis; and
a workpiece gripping structure mounted to said support structure comprising at least one workpiece gripping member having a workpiece-receiving surface, said gripping member being rotatable about a second axis substantially parallel to said first axis such that said gripping member is rotatable about said second axis during transfer of a workpiece from the first location to said workpiece-receiving surface, and said workpiece gripping structure further comprising a second drive motor for effecting rotation of said workpiece gripping member about said second axis, said workpiece grippin member also being rotatable about a third axis substantially perpendicular to said first and second axes so as to be capable of rotating said workpiece transferred to said workpiece-receiving surface through an angle, and said workpiece gripping structure further comprising a third drive motor for effecting rotation of said workpiece gripping member about said third axis, said first, second and third drive motors are independetly-controlled servo drive motors.

Abstract
A transfer apparatus is provided for transferring a workpiece from a moving anvil to a moving carrier. The apparatus comprises: a support structure comprising a support member rotatable about a first axis, and a workpiece gripping structure mounted to the support structure comprising at least one workpiece gripping member having a workpiece-receiving surface. The gripping member is rotatable about a second axis substantially parallel to the first axis such that the gripping member is capable of being rotated about the second axis during transfer of a workpiece from the moving anvil to the workpiece-receiving surface. The workpiece gripping member is also rotatable about a third axis substantially transverse to the first and second axes so as to be capable of rotating the workpiece from a first angular position at the anvil to a second angular position.
