An automatic, cam-actuated precision transfer apparatus operable to transfer and simultaneously invert workpieces between adjacent work stations. The transfer apparatus utilizes a common input shaft to provide input rotation to both a stationary oscillator device as well as an indexer device rotatably mounted atop the oscillator. The output of the oscillator device horizontally oscillates the rotatable indexer device through a desired number of degrees of rotation, and the indexer's output vertically indexes a turret-type transfer arm assembly which has associated pick and place units. The combined indexing and oscillating movements produced by the transfer apparatus allow a workpiece to be picked up at a first work station, vertically inverted while being horizontally transferred, and finally deposited at a second work station. The transfer apparatus is adjustable to accommodate any variations in manufacturing setups. |
