Abstract

A machine for picking up and placing parts includes an oscillating dial which carries a shuttle, an intermittently rotatable turntable which carries several angularly spaced fixtures, and vertically reciprocable lift platens which carry angularly spaced transfer or working devices, at least one of the devices being a transfer device having a gripper for holding and releasing parts. A part fed into the shuttle is carried to a transfer station by the shuttle and is picked up by the gripper of the transfer device as the latter moves downwardly through a long stroke and between adjacent fixtures. After the transfer device has been retracted upwardly through a long stroke to clear the fixtures, the turntable is indexed through one step to bring a fixture into underlying relation with the transfer device. The transfer device then is moved downwardly through a short stroke to place the part on the underlying fixture and thereafter is retracted upwardly through a short stroke to permit the turntable to index through another step and again locate adjacent fixtures on opposite sides of the transfer device preparatory to the next long downward stroke of the transfer device.
