Then, as described above, these operations are set to be an optimum combination in accordance with factors such as the processing time. As described above, in the laser processing system of this embodiment, since the flat plate-shaped works W can be carried in and out of the processing station 14 while being supported by the processing pallet 11 one by one, the works W are punched or otherwise processed. In that case, it is not necessary to connect the punched part with a micro joint, and it is troublesome to hit the processed work with a hammer etc. to separate the connection of the punched part and to polish the separated micro joint part. You can eliminate all the unnecessary work.

Further, in this embodiment, a large number of works W of different types can be sorted in advance for each type and stacked on the material pallet 3 and stored in the material storage station 1 in multiple stages. Therefore, even when performing plural types of laser machining using plural types of works W, the work W can be continuously carried in and out of the machining station 14 unattended, which saves labor during machining operation.

Therefore, in this embodiment, when the work W is loaded from the truck 53 to the work station 22, the work pallet 3 reciprocates the work pallet 3 between the work storage station 1 and the assembly station 5. Thus, the works W are stored in the material storage station 1 in multiple stages. During the processing operation, the work robot 52
Allows one work W at the assembly station 5.
Is replaced with the processing pallet 11 from the material pallet 3, and then the processing pallet 11 supporting the work W is carried into the processing station 14 and laser processing is performed. Further, the processing pallet 11 supporting the processed work W is processed by the work robot 52 at the processing station 14
It is carried out from and stored in a predetermined temporary storage station 9.
