ABSTRACT:
An e-coating line for small parts includes a series of load carriers, each having a rotatable shaft supporting an apertured metal barrel with parts to be treated. Electrically conductive drive chains and sprockets connect the rotatable shaft to barrel shafts to suspended the barrel from the carrier for submersion of the barrel into treating tanks including an e-coating tank. The chain/sprocket units are self cleaning and establish a reliable grounding of the barrels through the load carrier and slide rail conveyor conducting the load carriers to ground. A rack is mounted on a support secured to move with the load carriers. The rack engages a drive sprocket on the rotatable shaft. A push cylinder secured to the rack, moves the rack with the slide rail held stationary to rotate the shaft and coupled barrel. The system provides a low cost and effective grounding of the barrels and minimizes maintenance requirements and costs.
