Abstract
A tracking apparatus and method for urging a mistracking conveyor belt towards a correct travel path are disclosed. The apparatus and method utilize downstream shifting of an end portion of an idler roller due to mistracking of the conveyor belt for steering the belt back toward its correct travel path and a reaction force from the belt due to the steering thereof for energizing a tilting action of the idler roller to raise the downstream end portion thereof. The idler roller is mounted to the conveyor structure via a frame assembly including a tilt device mounted internally within the idler roller. The roller is rotatably mounted to an inner tube, and the inner tube member is pivotally mounted to the tilt device, which in combination allow the idler roller to pivot, shift, and tilt to steer a mistracking conveyor belt in relative proportion to degree of mistracking of the belt.
