Abstract
A tip-up and mounting apparatus in a sortation conveyor includes a support angle, upstanding mounting angles, mounting brackets, and a tray engaging roller mounted on crank arms pivoted to the mounting brackets. The mounting angles are disposed with their apices facing outwardly of the conveyor, thus providing a mounting surface at 45.degree. to the conveyor's machine direction for the mounting bracket. The crank arms are pivoted to the mounting bracket, and this configuration provides an in and out component of motion to the rollers during their movement to and away from sortation tray engagement, thereby maintaining a short roller dwell time in tray interfering position. Adjustable construction of the components, together with a self-aligning actuating cylinder mounted within the mounting bracket reduces bulk and provides a highly tunable and smoothly operating tip-up apparatus.
