ABSTRACT:
A part loading apparatus is disclosed for transporting a workpiece from a first position generally in a first plane to a second position generally in a second plane for transfer to another work station. The part loading apparatus includes a rail for transporting the workpiece between the first and second positions. A shuttle is disposed on the rail for reciprocally moving between the first and second positions. A drive motor is provided for harmonically driving the shuttle between the first and second positions, wherein the shuttle decelerates when approaching the first and second positions, and accelerates when leaving the first and second positions. A frame carries the workpiece from the first position to the second position and is supported on the shuttle for pivotal movement from the first plane to the second plane while the shuttle moves between the first and second positions.
