ンダー６で行うことが害来、大変便利である。As described above, the automatic pallet loading/unloading device according to the present invention is provided with a reciprocating carriage 3 between the workpiece placement location 1 and the processing station 2. A pallet 17 that can be moved one after another on the processing station 2 is placed, and a machining/dressing chain 9 for engaging with a rack 18 provided below the pallet 17 is placed in the carriage 8 and fixed to the base 4. The rotation of the pinion 10 that meshes with the dental gear 11 is transmitted to the running of the endless chain 9 via an arbitrary power transmission means, and the moving speed of the cutting/dressing chain 9 is configured to be faster than the moving speed of the carriage 8. The movement of the gear range and the running of the endless check are carried out by a set of Akushima uniters, that is, the first telescopic cylinder 5. It is very convenient to do this with the second telescopic cylinder 6.
