Abstract
A system for correcting transverse misalignment of a conveyor belt relative to a supporting pulley, includes a frame is pivotally attached to a stationary member. A guide surface engages the frame to guide pivoting of the frame about the pivot point simultaneously about a vertical axis and a longitudinally aligned axis. Idler rollers rotatably mounted on the frame define a rolling contact surface for the conveyor belt, which is concavely-shaped in a transversely-extending vertical plane. The pivoting of the frame causes the surface to impart a combined transverse pushing effect, torsional steering effect, and torsional tiling effect on the conveyor belt. An actuator applies a force to pivot the frame about the axis. A computer determines an amount of the misalignment based on a signal from a sensor, and automatically controls the actuator to pivot the frame, depending on the determined amount of the misalignment.
