A pick-off mechanism for a high-speed medicinal capsule inspection machine or the like. Bulk capsules are loaded from a hopper to a chain conveyor, rectified, and transferred to an inspection head. A circumferential series of rolls on the head defines vertical grooves to receive and spin capsules on their axes. The head indexes forward to carry capsules stepwise from the loading station, through an optical-electronic inspection station, to a transfer point. There, the capsules are transferred to a pick-off wheel, which indexes forward in timed relation with the head. The capsules are received on spaced seats on the pick-off wheel, and held thereon by suction. Each unacceptable capsule is swept off the pick-off wheel at an early point in the capsule movement on the pick-off wheel, by projecting a reject arm into the capsule path in response to the inspection results. The rejected capsules fall to a reject chute. Acceptable capsules are carried further by the wheel to a discharge point, where a cam removes them to an accept chute. |
