Image Number 2 for United States Patent #5997241.
A system and a method are provided for automatically loading and unloading pallets holding a workpiece for machining of the workpiece within a machining area. The pallets are loaded into the machining area by transfer of a pallet from the staging area to a machining area. Rails which maintain the pallets within each area are aligned. An arm having pins at each end engages passageways associated with the pallets and the machining area, respectively. As a result, the pallet may be transferred from the staging area to the machining area and back as the arm translates within the passageways.
