Abstract:
1. An alignment system for a conveyor having a conveyor belt trained over rollers on a conveyor frame, the system comprising: a shaft including a plurality of tracking rollers and opposing ends; pivoting members each mounted on a corresponding support bracket, one of said pivoting members being coupled to each of said ends of said shaft; each of said ends of said shaft being pivotally and non-rotatably attached to a corresponding one of said pivoting members by a rotating bushing mounted in a corresponding one of each of said pivoting members; and a guide control bar having two ends and being pivotally connected at each said end to a corresponding torque arm, each said torque arm being connected to said corresponding pivoting member; and a pair of guide rollers positioned at both edges of the conveyor belt, one of said guide rollers being connected to and extending from each of said ends of said guide control bar, wherein lateral movement of said guide rollers due to contact with the conveyor belt causes reciprocal movement of said shaft for controlling lateral movement of said belt.
