Part S _A of the processed is unloaded lifted by suction by the suction pads 51 of the unloader 9 are integrated into a predetermined location of the parts storage 7 (step S10).

Next, the process proceeds from step S11 to step S6 and S7, in FIG. 1, for example, as other parts in the workpiece W on the right part S _B in the NC program 59 as shown in FIG. 3 Next machining program 61
It is processed based on.

[0064] When processing of the part S _B ends, from being performed to read only the integrated data from the G code likewise part S _B and the part S _A, is transmitted by M code on the line controller 55 integrated data Receiving memory 8
1 is stored. The G-code part S _B, X_Y_ indicating the last processing position of the part S _B is registered, since being transmitted in the same manner as described above in Part S _A this time a small amount of data only aggregate data It is transmitted in a short time (steps S8 and S9).

[0065] Integrated data of the part S _B is the part data receiving data is matched with the part data of the part S _B stored in the memory 79 for part retrieval of part S _B. Based on data of the parts for taking out unloading of parts S _B of the processed into unloader 9 of the work loading and unloading device, is given integrated command. Parts _{S B} is unloader 9
Is carried out to a predetermined place in the parts storage 7, and is accumulated (step S10).

As described above, when all parts in the first work W have been processed, it is confirmed whether or not the required number of each part has been processed (steps S11 and S12).

For the second and subsequent works W, step S12 is performed.
From step S1 to the line controller 55
Gives a command to the loader 5 of the work loading / unloading device from
One piece of work W is taken, and turret punch press 1
(Steps S1 and S2).

[0068] Also part S _A in the second piece of the workpiece W in the same manner as the first sheet of parts S _A, after the loaded workpiece W is processed on the basis of the machining program 61, G of Part S _A
After reading only the integrated data from the code, the data is transmitted to the line controller 55 (step S
6 to S9).

[0069] Integrated data of the part S _A is the data for the part take-out is matched to the part S _A of part data in the part data receiving memory 79, the unloader 9 on the basis of the data for the part is taken out of the part S _A Is carried out to a predetermined place in the parts storage 7 and is accumulated (step S10).

[0070] Part S _B in the second sheet of the workpiece W is also similar to the part S _B of the first sheet, after being processed on the basis of the machining program 61, read only integrated data from the G-code part S _B Line controller 5 after being performed
5 is sent. Are matched to the part S _B of the part data of the current product data of the part S _B is the part data receiving memory 79 is the data for the part is taken out, the unloader based on the data for the part is taken out of the part S _B 9 and carried out to a predetermined place in the parts storage 7 and accumulated (steps S6 to S10).

[0071] If more than three or more parts in the workpiece W as is processed also, may further machining required number of sheets is performed, as in the case of the part S _A and Part S _B , Processed, carried out and accumulated.

It is not necessary to transmit the part data of each part to the line controller 55 for the second and subsequent workpieces W. After each part is processed based on the processing program 61, each part data in the NC program 59 Since only the integrated data of the parts is transmitted from the processing machine controller 53 to the line controller 55, the stop time of the plate material processing machine when unloading the processed parts is greatly reduced.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. In this embodiment, a turret punch press has been described as an example of a plate processing machine, but other punch presses, laser processing machines, and other plate processing machines may be used.

Although the loader and the unloader are provided with the suction pads in the above-described embodiment, a suction device such as a magnet or an unloader clamp may be provided.

[0075]

As can be understood from the above description of the embodiment of the invention, according to the first aspect of the present invention, the part extracting data in the control program is divided into part data and integrated data, The transmission of the part data from the processing machine controller to the line controller is performed before the start of the processing of the work, that is, during the unloading work loading operation of the work loading / unloading device, so that time can be effectively utilized. When the processing of the workpiece is completed, only the integrated data is transmitted, so that the transmission data amount is small, so that the transmission can be performed in a short time. As a result, the stop time of the plate material processing machine at the time of unloading each processed part can be reduced, and as the number of parts increases, the time is greatly reduced.

Further, it is not necessary to transmit the part data of each part when processing the second and subsequent workpieces, and only the integrated data of each part is transmitted at the end of processing each part.
The downtime of the plate processing machine when unloading parts can be greatly reduced.

According to the second aspect of the present invention, the effect is basically the same as that of the first aspect, wherein the part extracting data of all parts in the control program is divided into part data and integrated data. Since the transmission of the part data of all the parts from the processing machine controller to the line controller is performed before the start of the processing of the work, that is, during the unloading work loading operation of the work loading / unloading device, time can be effectively utilized. As a result, since the amount of transmission data is small, transmission can be performed in a short time, and the stop time of the plate material processing machine when unloading the processed parts can be reduced.

Further, when processing the next part and each part of the second and subsequent workpieces, it is not necessary to transmit the part data, and when the processing of each part is completed, only the integrated data of each part can be transmitted in a short time. The time is greatly reduced, and as the number of parts increases, the time can be significantly reduced.

According to the third aspect of the present invention, similarly to the first aspect, the part extracting data in the control program is divided into the part data and the integrated data, and this part data is transferred from the processing machine controller to the line. Since the transmission to the controller is performed before the start of the processing of the work, that is, during the unprocessed work loading operation of the work loading / unloading device, time can be effectively utilized. When the processing of the workpiece is completed, only the integrated data is transmitted, so that the transmission data amount is small, so that the transmission can be performed in a short time. As a result, the stop time of the plate material processing machine at the time of unloading each processed part can be reduced, and as the number of parts increases, the time is greatly reduced.

Further, it is not necessary to transmit the part data of each part when processing the second and subsequent workpieces, and only the integrated data of each part is transmitted at the end of processing of each part.
The downtime of the plate processing machine when unloading parts can be greatly reduced.

According to the fourth aspect of the present invention, it is the same as the effect of the second aspect, and divides the part extracting data of all the parts in the control program into the part data and the integrated data. Since the part data is transmitted from the processing machine controller to the line controller before the processing of the work is started, that is, during the unloading work loading operation of the work loading / unloading device, the time can be effectively utilized. As a result, since the amount of transmission data is small, transmission can be performed in a short time, and the stop time of the plate material processing machine when unloading the processed parts can be reduced.

Further, when processing the next part and each part of the second and subsequent workpieces, transmission of the part data is unnecessary, and only the integrated data of each part can be transmitted in a short time at the end of processing of each part. The time is greatly reduced, and as the number of parts increases, the time can be significantly reduced.
