International ClassG01N 021/90AbstractApparatus for inspecting the sealing surfaces of containers that includes a light source positioned to direct a narrow beam of light energy at an acute angle onto the sealing surface of a container as the container is rotated about its central axis. A light sensor is disposed to receive the narrow beam of light energy reflected from the sealing surface, and provides an output signal that varies as a function of position of incidence of the reflected light beam on the sensor. The sensor is coupled to associated electronics for providing information indicative of container height, and a signal for controlling separation of a container from the conveyor system when height of the container, warp or dip of the container sealing surface, or cocked finish at the container exceeds predetermined standards. | |
