PURPOSE:To have automatic replcement of works to be processed, which does not require any major space, by arranging a work holding device, in which the axis of work held is not in parallel with that stored in a work storage device, so as to be in relative inclination by a certain specified angle to a work which the replacement arm is going to grasp. CONSTITUTION:To replace works to be processed, a work replacement device 3 acts on the work holding device 2 of a machine tool 1. This replacement device 3 includes a work storage device 4 and a replacing arm device 5. A work is mounted on a pallet 6 with replaceability. A work mounting/demounting device 7 removes the work processed from a pallet 6, and an unprocessed work is mounted thereon. A pallet 6 with unprocessed work is mounted or demounted by the work replacement device 5 at a pallet mounting/demounting device 8. The replacing arm device 5 has a replacing arm 31. The arm 31 displaces round a column 180 deg. to be shifted from the vertical to horizontal position and performs the desired action. |
