Abstract
A workpiece changer for transfer of workpiece palettes between a storage arrangement arranged in front of a machining machine for such workpiece palettes and a workpiece table, possesses a gripper device for receiving and putting down workpiece palettes and a rotary drive for swiveling the gripper device about a vertical axis. A linear drive serves to shift the gripper means between a first position on the storage arrangement and a second position on the workpiece table. The storage arrangement possesses at least one change station for the transfer and acceptance of workpiece palettes by the gripper device, a conveyor apparatus being provided for the supply and removal of workpiece receiving station to and from the change station. Accordingly, satisfactory access is provided to the workpiece table during machining and workpiece changing operations may be performed at a high speed on any desired machining machines.
