Abstract
A conveyor system is disclosed for transporting workpieces. The conveyor system includes an elongated frame having an inlet end and an outlet end. A pair of sprockets are rotatably mounted to both the inlet end and outlet end while a pair of closed loop chains are mounted around the sprockets so that the chains are spaced apart and parallel to each other along the frame. A motor rotatably drives the sprockets and thus the chains along the frame. A plurality of pallets, each adapted to support a workpiece, are slidably mounted to the chains by rollers so that the pallets can move longitudinally with respect to the chains. A cam is secured to the sprockets at both the inlet and outlet ends of the conveyor frame. These cams engage a cam follower on the pallet to raise the pallets from a lower section of the chain to an upper section at the inlet end of the conveyor frame and vice versa at the outlet end of the conveyor frame. The frame is formed from F-shaped extensions which support and guide the chain.
