Abstract: A pallet conveyor system includes a rail assembly and a pallet assembly. The rail assembly including parallel and spaced-apart rail supports that each has a cylindrical rail disposed thereon. An intermediate support is positioned between the rails and includes a removable stop bar. The pallet assembly engages the rails and is adapted for forward or reverse motion along the rails. A first and second sensor are secured to the pallet assembly and adapted to detect the stop bar as the pallet moves along the rails. When the first sensor detects the stop bar, the pallet assembly is slowed. Thereafter, as the second sensor detects the stop bar, the pallet assembly is stopped. Therefore, by simple movement of the stop bar, a pallet assembly may be easily and precisely positioned at any location along, a conveyor line without the need to reprogram the pallet assembly.
