Patent ID: 11141827

Abstract:
A workpiece replacing apparatus delivers a pre-machined workpiece into an intra-machine space inside a machine tool from an extra-machine space outside the machine tool, and delivers a workpiece machined by the machine tool to the extra-machine space from the intra-machine space. The workpiece replacing apparatus includes a secured cover, an arm device, and a movable cover. The secured cover is secured to a securing member of the machine tool. The secured cover defines a partition between the intra-machine space and the extra-machine space. The secured cover is provided with an opening. The arm device delivers the workpieces between the intra-machine space and the extra-machine space through the opening. The movable cover is integral with the arm device or in engagement with the arm device such that the movable cover is operable in conjunction with operation of the arm device. The movable cover closes the opening, with the arm device located in the extra-machine space.
