DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material processing method and a sheet material processing apparatus for performing schedule processing.

[0002]

2. Description of the Related Art Referring to FIG. 4, conventionally, in a turret punch press line schedule operation, when a large number of small products are formed in a single material, a sheet material W is required.
Is loaded (step S101), and processing is performed in the trial hitting mode, only one small product is trial hit (step S102) and unloaded (step S103).

[0005] Alternatively, as shown in FIG. 5, loading is performed (step S104), and test hitting is performed (step S105). During this trial processing, the line operation switch is turned off (step S106). When the trial processing is completed, the product is confirmed (step S107). If OK, remaining processing is performed on the same trial-processed plate material W (step S108), and unloading is manually performed (step S109). Subsequently, scheduling of the remaining number is performed (step S110), and the line operation switch is turned on (step S111). After performing the processing by changing to the all processing mode (step S112), the processing is ended (step S113).

[0004]

However, in such a conventional technique, in the schedule operation shown in FIG. 4, the setting of the trial run of multi-cavity setting, the remaining machining, and the setting of all machining are performed on the NC side. There is a problem that can only be done in.

[0005] Also, in the schedule operation shown in FIG. 5, after the trial driving, the line operation switch is turned off and the operator checks the product. There is a problem that the remaining scheduling must be performed and workability is poor. In other words, when a trial shot is to be performed, the plate material W is taken from the shelf for the trial shot, processed, and the product is manually conveyed to the product shelf. This depends on the size of the plate material W (for example, SPCC (plate thickness 2 mm) 4 ″ ×
8 ") will be hard labor for workers.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet material processing method and a sheet material processing apparatus capable of performing a scheduled operation from the first sheet for performing test punching. It is in.

And a control device for controlling the sheet material processing machine based on the schedule data input by the input means.

Therefore, when a large number of products or the like are taken from a sheet material by a sheet material processing machine, even if trial processing is performed on the first sheet, then the remaining processing is performed, and all the processing is performed from the second sheet, the input means may be used in advance. If the trial data and the remaining processing are input as schedule data, the control device performs the trial processing and the remaining processing on the first sheet by the schedule processing, and sets the sheet material processing machine to perform all the processing from the second sheet. Control.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an entire plate processing apparatus 1 according to the present invention. The plate processing apparatus 1 includes, for example, an NC punch press 3 as a plate processing machine, a single-sheet loader 5 that supplies the plate W to the NC punch press 3 on one side in the vicinity thereof, and An unloader 7 for taking out the processed product is provided.

The NC punch press 3 has a punch press NC device 9 for controlling the NC punch press 3. The punch press NC device 9 has a CPU 11 which is a central processing unit.
Keyboard 13 or CRT as an example of input means
15 output devices. The CPU 11
Has a RAM 17 and a program memory 19 as storage means.

A control device 21 for controlling the punch press NC device 9, the single-sheet loader 5, and the unloader 7 is connected thereto. The control device 21 has a CPU 23 as a central processing unit.
Reference numeral 23 denotes a keyboard 25 or CR as an example of an input unit.
It has an output device such as T27. Also, CPU2
3 has a schedule memory 29 as storage means and a memory 31 storing schedule software for trial hitting and remaining machining.

Next, the procedure of the NC machining method according to the present invention will be described with reference to FIG. First, when processing is started (step SS), a loading command is issued and the sheet material W
Is loaded into the NC punch press 3 by the one-sheet pick-up loader 5 (step S1), and the control device 21 determines whether or not the apparatus is in the full machining mode (step S2).

In the all machining mode, the control device 21 instructs the punch press NC device 9 to perform all machining (step S3), and issues an unloading command to the unloader 7 (step S4). The control device 21 adds the number of processed plate materials W (step S5), determines whether or not the number of processed plates W has been reached (step S6), and when the number has reached, ends the processing or proceeds to the next processing. (Step S7).

On the other hand, in step S2, the control device 21
When it is determined that the mode is not the all machining mode, the control device 21 instructs the punch press NC device 9 to perform test hitting (step S8), and performs test hitting so that the operator can confirm the result of test hitting. The plate material W thus returned returns to the origin alone (step S9). If necessary, the operator confirms the result of the test hitting (step S10). However, in consideration of a wrong mold or a program error, the operator can manually edit the result.

Subsequently, the control device 21 controls the punch press NC.
The start button is turned on by instructing the apparatus 9 (step S11), the remaining machining is performed (step S12), and the unloading instruction is issued to the unloader 7 (step S1).
3) After adding to the number of processed sheets, the mode is changed to the all processing mode (step S14). Then, it is determined whether or not the number of processed sheets has been reached (step S15). If not reached, the procedure returns to step S1 to repeat the subsequent steps ((steps S1 to S6)) as the all processing mode. Ends the processing or moves to the next processing (step S
16).

Referring to FIG. 3, an example of the scheduler screen is shown. In the sheet material processing method according to the present invention, a column of “multiple-piece setting” is provided in addition to the conventional screen. The settings in the punch press NC device 9 are invalid during the line operation. If the program is not a multi-cavity program, all processing is performed for both "test remaining" and "all".

Here, the "remaining trial" processing is set when the user wants to confirm the product after performing trial hitting.
After test-trimming the first sheet, the product is checked, and after remaining processing, all processing is performed from the second sheet. In this setting, the machine stops after the test strike. In addition, since “all processing” is performed in non-stop operation, if product confirmation is performed during working hours, it is suitable for night operation.

In the case of the schedule as shown in FIG. 3, N is a program in the punch press NC unit 9.
O. Processing is started from 0001. According to the flowchart of FIG. 2 described above, the remaining processing is performed on the first sheet after test hitting, and a total of 10 sheets are processed on the second sheet. Next, N
O. In 0002, all 10 sheets are processed, and thereafter, the processing is sequentially performed.

From the above results, the schedule operation can be performed from the first sheet material W on which the test driving is performed, so that the work efficiency can be improved.

It should be noted that the present invention is not limited to the above-described embodiment of the present invention, but by making appropriate changes,
It can be implemented in other aspects. That is, in the embodiment of the invention described above, the plate processing machine is NC
Although the case where the punch press 3 is used has been described, a laser processing machine or the like may be used as another plate material processing machine.
