Abstract
A conveyor alignment system including pivoting members that support tracking rollers at corresponding shaft ends. Each shaft end being pivotally and non-rotatably attached to corresponding pivoting members by a rotating bushing mounted in a corresponding one of the pivoting members. A guide control bar is pivotally connected at each end to a corresponding torque arm, where the bar includes guide rollers positioned at both edges of the conveyor belt for lateral control of the belt. A spacer is mounted to the support bracket and has a designated height. The spacer deflects the support bracket by the height so that a first end of the shaft is closer to the a first side of the belt than an opposing, second end of the shaft to increase the tension of the rollers on the first side of the belt and reduce the tension of the rollers on another side of the belt.
