A pallet is releasably attached to a car which is stopped automatically at a work station in a coarse alignment with a robotic system at the work station. A movable plate, which tends to be distorted from a given shape, is releasably secured to the car and lifted from the car at the work station, aligned in the desired fine alignment during the lifting and then clamped in place relative to a reference plane in the fine alignment relative to the robotic system to remove the distortion. The plate is later dropped by gravity onto the car in a given alignment therewith for transfer to the next work station which repeats the fine alignment and distortion removal action.

A system for transferring a body to a work station, said body including means adapted to carry a workpiece, said system for orienting and clamping the transferred body to a support at the work station, said system comprising: a support having a plurality of stationary spaced reference surface defining a reference plane at said work station; transfer means movably coupled to the support for displacement into the work station in a coarse alignment with said surfaces at the work station; said transfer means including a body movably secured thereto, said body having a plurality of spaced reference surfaces, each corresponding to a different one of said support reference surfaces; said body and transfer means including alignment and securing means for movably securing said body to said transfer means in a given alignment therewith so that the body can displace a limited distance relative to the transfer means while remaining secured to the transfer means; actuating means secured to the support at the work station including means responsive to said coarse alignment of said transfer means with said support reference surfaces for displacing said body from said transfer means within said limited distance and for locking said body reference surfaces in engagement with said support reference surfaces at said reference plane; and body aligning means secured to said actuating means and to said body for automatically aligning said movably secured body in a fine reference alignment relative to said coarse alignment in response to and during said displacing of said body prior to said locking.
