ABSTRACT:
The arrangement for loading and unloading workpieces of machine tools includes a pair of spaced loading arms supported on a carriage for pivoting about a first axis. A pair of spaced unloading arms are also supported on the carriage above the loading arms for pivoting about a second axis parallel to the first axis. Each arm carries a gripper for the workpiece, and each pair of grippers is movable by the associated arms along an arcuate path between an initial position and an end position. The initial positions of the two pairs of grippers are different but the end positions are common. The carriage is movable from a workpiece magazine, where the loading arms pick up an unmachined part and the unloading arms subsequently release a machined part, to a position within the work space of the machine where the unloading arms pick up the machined part and the loading arms subsequently position the unmachined part for machining.
