ABSTRACT:
A system and method for inspecting and rejecting defective containers comprising a plurality of reflective infrared sensors, an electronic logic control and a container removal device. The system assesses the quality of the flange of the container and senses the height of the container by sensors irradiating the flange portion of the container with narrow beams of infrared light at varying heights and receiving radiation reflected from the flange portion. The acceptability of the container is determined by the quantum of reflected radiation received by the sensors. Unacceptable containers are removed by a high-speed pneumatic cylinder coupled to independently controlled, solenoid-operated air valves which govern the movement of the cylinder piston of the pneumatic cylinder.
