A conveyor apparatus for use with a conveyor belt includes an elongate conveyor support frame and a plurality of conveyor belt supporting devices mounted on this frame. These devices include a tail pulley mechanism having two tail pulley sections mounted on a pulley support member for rotation about a common central axis of rotation. The pulley support member includes a central support portion located at inner ends of the pulley sections and extending radially outwardly from these inner ends to a vertically extending pivot axis. An interconnecting support arrangement mounts the pulley support member on the conveyor support frame and includes a pivot connector connecting the central support portion for pivotable movement about the pivot axis. One embodiment includes an actuator for pivoting the pulley support member about the pivot axis to maintain the conveyor belt within a central region of the tail pulley and an electronic controller for controlling operation of this actuator. Light beam sensors are used for sensing a shift of the conveyor belt out of the central region.
