  • Patent number: 4411576
    Abstract: A pick and place mechanism is provided for selecting a part from a pick-up location, transporting the same to a place location, and placing it in a precise position at the place location. A part is engaged by a pair of gripping fingers which depend from a casing mounted for movement between the pick and place locations. The fingers are connected to a cam mounted for reciprocation in the casing to alternately extend and retract the fingers. The fingers cooperate with an actuating mechanism carried by the casing to engage and disengage the part in response to movement of the cam. The cam is normally biased upwardly and is actuated by a follower which is guided in a slot in the casing, and an air cylinder drives the follower and hence the casing between the pick and place locations.
