Abstract
A dip coat process material handling system and method for coating multiple layers of material on a plurality of workpieces, in particular for producing a multi-layer optical photoconductive drum, wherein a plurality of pipes are suspended from a carrier pallet which transports the workpieces through a dip coat cell housing various dip coating stations. The system includes a load/unload station, vertical and horizontal transport systems for transporting the carrier pallet having workpieces loaded thereon to the various dip coating stations, a drying/cooling booth, and a return conveyor system. The invention allows complete dip coat processing to be completed in an in-line configuration while the workpieces are attached to the carrier pallet, thereby eliminating load/unload steps at each dip coating station to provide efficient and flexible processing of materials.
