2. Description of the Related Art In a laser processing apparatus, a work is loaded and unloaded from a work loading station to load a non-worked workpiece onto a processing table, machine the workpiece, and automatically unload the processed workpiece from a processing position to a unloading station. Conventionally, there are two types of devices. The first work loading / unloading method is to directly load the pallet and the work to the processing position of the laser processing machine while the work is placed on the pallet. In the second loading / unloading method, a large number of pallets (usually about four) are arranged at the loading and unloading positions respectively, and the work placed on the upper surface of the pallet on the loading side is transferred by the transfer device. The work is carried into the processing table of the laser processing machine, and the processed work is carried out from the processing table to the upper surface of the pallet on the carrying side.

[0003]

However, in the first work loading / unloading method of the laser processing apparatus described above, since the pallet is loaded / unloaded on / from the processing table of the processing machine together with the work, a large-scale driving device is required. However, there is a problem that the manufacturing cost cannot be suppressed. Further, there is a problem that a waiting time is required until the next machining is performed after the machining of one work is finished, and the efficiency of the machining work cannot be improved.

The second work loading / unloading method not only requires a wide installation space for arranging a large number of pallets (usually about four) at the loading position and the unloading position, but also the waiting time described above. However, there is a problem in that the efficiency of processing work cannot be improved.

The present invention has been made by paying attention to the problems existing in such a conventional technique, and an object thereof is to reduce a manufacturing cost by eliminating a large-scale drive device. is to provide a laser pressurized KoSo location that can be reduced installation space can be improve work efficiency by further reducing the latency of the processing operations.
