ABSTRACT:
A sensor roller and method for detecting the presence of a tray located thereon, where the tray is traveling along a conveyor system, includes a housing having an interior chamber and a plurality of apertures. The apertures are in one-to-one correspondence with actuators, where the actuators each have an exposed portion protruding through the apertures. The sensor roller further includes a piston slidable in the interior chamber of the housing and engaging the actuators. The piston slides between a non-actuated position to an actuated position in response to a tray travelling along the conveyor system depressing an actuator into the interior chamber of the housing. A sensor detects the presence of the piston in the actuated position and generates a detection signal in response thereto.
