Abstract: The invention is directed to an apparatus for detecting and ejecting fallen containers on a conveyor line. The detecting apparatus includes at least three sensors arranged beside the conveyor system. Two of the sensors are positioned to detect the top of a container and a third sensor is positioned to detect the bottom of the container. When a container is judged to be fallen on the conveyor line, a control system sends a signal to an ejector apparatus to remove the fallen container from the conveyor line.
