ABSTRACT:
A lateral sensor positioned proximate to at least one of the edges of a conveyor belt continually monitors the position of the edge of the conveyor belt. If lateral movement is detected by the lateral sensor, an adjustment motor rotates to move an end of a non-drive pulley to adjust for the lateral movement. The lateral sensor can be a non-contacting inductive proximity sensor, a proportional sensor such as a linear variable displacement transducer or a linear potentiometer which determines if the edge of the conveyor belt has moved laterally by monitoring the resistance in the spring, or a Hall effect sensor.
