  • Patent number: 9033135
    Abstract: An alignment system for a conveyor having a conveyor belt trained over rollers on a conveyor frame where the system includes a support bracket including a center support and pivoting members each including a torque arm, the pivoting members being pivotally mounted to opposing ends of the support bracket. Two tracking rollers are independently mounted to the support bracket, where each of the tracking rollers includes a shaft with an inner end and an outer end, the outer ends of the shafts being coupled to the pivoting members and the inner ends being coupled to the center support such that pivoting movement of the pivoting members causes the tracking rollers to pivot relative to the center support. A guide control bar having two ends is pivotally connected at each the end to a corresponding torque arm connected to the corresponding pivoting member, where the guide control bar includes guide rollers positioned at both edges of the conveyor belt for lateral control of the belt.
