ABSTRACT:
A reversed can end ejector system is provided for detecting and ejecting a can end in reverse orientation with respect to a moving stack of otherwise similarly aligned and nested can ends. This system comprises an optical detection apparatus including a light-emitting portion for emitting light in a direction toward the path of travel and a light-detecting portion located adjacent said path of travel. The optical detection apparatus is responsive to one of the presence or absence of light incidence upon its light-detecting portion for producing a control signal. An ejector is movable relative to the stack for contacting and ejecting a reversed can end therefrom and an actuator is coupled with the ejector and responsive to the control signal for driving the ejector in a direction for contacting and ejecting the reversed can end from the stack.
