Abstract
A conveyor drive system including an improved control circuit for a glass manufacturing apparatus transports a glass sheet through a glass processing station. The conveyor drive system includes first and second conveyor drives disposed on opposed lateral sides of the station. Each of the conveyor drives includes first and second pulleys and a continuous drive loop trained thereover. The glass plate is supported on a plurality of elongated rollers that extend between the conveyor drives and have their opposed ends supported on and in frictional engagement with the continuous drive loops. A drive motor applies drive torque to the first pulleys, and a pair of counter-poised drive motors apply a counter-torque to the second pulleys. The control circuit for controlling the energization of the first drive motor and the pair of counter-poised drive motors includes a feedback circuit which provides degenerative speed feedback for stabilizing the motion of the conveyor drive system.
