2. Description of the Related Art In the prior art, parts (work)
For a certain number (lot) of continuous flow, marking information is prepared in advance and then marking is performed. That is, referring to FIG. 5, in the conventional plate material processing apparatus, the controller 105 controls the processing machine 107 by the schedule operation according to the data stored in the schedule database 103 based on the input basic data 101, and the processing data 109 After processing the workpiece W according to the above, the marking device 111 is controlled to perform marking on the workpiece W according to the marking data 113. Then, the process proceeds to the next step. At this time, the processing data 109 and the marking data 113 for the component W are stored as the basic data 101 for each component as a set.

When the number (lot) is large or the marking information is small, the marking data may be stored directly in the marking device, referred to, and used instead of preparing the marking data in advance. In addition, the marking here includes a label, a printer, a barcode, an ink jet, a laser marking, an engraving, and the like.

Subsequently, the line control unit 37 receiving the instruction from the schedule operation processing unit 35 reads the schedule from the online schedule database 31 and starts the allocation schedule DNC operation (step S).
3), for example, the sheet NC of S1 corresponding to the schedule
Data is read from the sheet NC database 29 and D
An NC operation is performed (step S4).

The order of picking up parts from the corresponding sheet S1 is output from the plate material processing machine 7 to the marking determination processing section 39 (step S5). This means that within the same sheet, the take-out order is ♯1 → ♯n, where ♯n is increased to the number of parts removed. The parts removal order {n of the corresponding sheet S1 to {
The n-th part information is read (step S6).

Next, the marking determination processing section 39 performs a marking determination process (step S7). In executing the continuous schedules S1 to Sm in this process,
Read the relevant part (figure part number) information. As the marking mode, for example, 1) all parts are marked,
2) First + last parts, 3) First parts,
There are 4) the last part target, 5) all parts marking non-target, etc. By considering such a mode, it is always possible to easily recognize the first part to be processed in the next process. This mode can be set and changed freely by the operator.

Next, when the marking judgment processing is completed,
Only when the marking process is performed, the marking is determined (step S8), the marking position command (step S8).
9), capture of marking data (step S1)
0), a marking instruction and a marking process are performed (step S11). It is determined whether the schedule S1 is completed and all schedules are completed (step S1).
2) If not completed yet, return to step S4 and execute the next schedule in sequence. If all the schedules have been completed, the process ends (step SE).

From the above results, it is possible to perform marking on each component of the nested sheet material using the marking data input for each component. As a result, it can be used as an identification ID for physical distribution tracking of an article separated from a sheet material into parts. This can be applied to, for example, physical distribution control from a drilling process by an NCT or a laser processing machine to a bending process by a bender, for example.

Further, it can be used as identification of inventory management at a processed sheet material level and a part level after separation.

Further, in response to a design change or a change in the number of products to be manufactured,
Since a series of data from the production plan to the scheduled operation can be reflected, when a change occurs in the production plan or the like, marking corresponding to the change can be performed.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes.
