Each data is similarly determined for D. Thus, the processing data and the printing data are stored in the data storage means 6 for each processing component.

A printer 8 shown in FIG. 1 comprises a printer control section 9 and a printer head 10. For example, an ink jet printer as disclosed in JP-A-63-86286 is used. An encoder 11 detects the speed at which the X-axis or Y-axis table is moved by the driving means 5. For example, one rotation of the motor shaft of the motor shaft of the NC motor constituting the driving means 5 is detected. This is to generate a synchronizing signal such that one pulse is output every time. Reference numeral 12 denotes a control unit, which is various data stored in the data storage unit 6, that is, print data,
Processing data and the like are extracted and processed, and the driving means 5, the processing machine 4, and the printer 8 are controlled.

The control unit 12 processes the material carry-in data stored in the data storage means 6, moves the work material 1 to the X-axis and Y-axis tables of the driving means 5, and fixes it by fixing means (not shown). The printer preparation data in the data storage means 6 is extracted and processed, and the driving means 5 is driven to move the X-axis and Y-axis tables to the machine origin by the NC motor. The control unit 12 takes out and processes the printing NC data stored in the data storage unit 6, drives the driving unit 5 again, and moves the processed material 1 to the printing reference point.
That is, the work material 1 is brought to the position of the printer head 10, for example, at the K position shown in FIG.

The print data stored in the data storage unit 6 is transmitted to the printer 8 via the control unit 12 . When printing on the processing material 1, the X-axis table is moved in the X-axis direction by the motor of the driving means 5, and when the printing start position N shown in FIG. 3 is reached, the printer 8 is synchronized with the synchronization signal from the encoder 11. Prints a character or a barcode based on the print data on the work material 1. Similarly, a plurality of printings are performed on the processing material 1. Next, the control unit 12 drives the driving unit 5 to extract the processed data stored in the data storage unit 6 and process the processed data in the same manner as when printing is performed. (O position), and a punching process is performed by a punch and a die by the processing machine 4 to form a processed part A1. The other processed parts A2, B, C, D are formed in the same manner.

FIG. 4 is a block diagram of a machined part printing apparatus according to the present invention, which is further embodied. In FIG. 4, reference numeral 13 denotes an NC device for storing NC data. This N
The C data stores positioning data for a printing reference point, printing auxiliary command data, printing movement data, processing data, and the like. 14 is an NC turret punch press,
The work material 1 between the punch and the die is subjected to processing such as punching and has an X-axis and Y-axis table on which the work material 1 is placed, and the table is moved in the X-axis direction and the Y-axis direction. An NC motor is provided. 15 is a calculator,
While transmitting the NC data and storing it in the NC device 13,
The character string data stored in the memory in advance is transmitted to the inkjet printer 9 . 16 is a sequencer, NC
The device 13, the computer 15, and the inkjet printer 8 are operated, and a timer 17 is provided.

The signal flow of each device in the configuration shown in FIG. 4 will be described with reference to the flowchart of FIG.
The computer 15 transmits the NC data 18 to the NC device 13. The NC device 13 stores the NC data 18,
The positioning data for the printing reference point of the C data 18 is processed, and the NC turret punch press 14 is driven to move the processing material 1 and position the processing component to the printing reference point 19. After processing the positioning data for the printing reference point of the NC device 13, it processes the printing auxiliary command data and transmits a print request signal 20 to the sequencer 16.

On the other hand, the computer 15 sends a status confirmation signal 21 of the print request flag to the sequencer 16. When receiving the status confirmation signal 21 and the print request signal 20, the sequencer 16 sets a print request flag and transmits a print request reception signal 22 to the computer 15. The computer 15 receives the print request flag, transmits the character string data 23 stored in the memory in advance to the inkjet printer 8, and receives a reception completion signal 24 from the inkjet printer 8. At this time, the computer 15 sends a print command signal 25 to the sequencer 16. When the sequencer 16 receives the print command signal 25, the sequencer 16 changes the print auxiliary command completion signal 26 to NC.
Transmit to the device 13.

The NC device 13 outputs a printing auxiliary command completion signal 2
After confirming No. 6, the printing movement data of the NC data is processed, and the NC motor of the NC turret punch press 14 is driven to move the processed part for printing. After transmitting the printing auxiliary command signal 26 as described above, the sequencer 16 transmits the printing command signal 27 to the inkjet printer 8 with a delay of a predetermined time by the timer 17. The ink jet printer 8 receives the print command signal 27, detects the print position (corresponding to the N position in FIG. 3) of the processed part by the encoder 11, and outputs the synchronization signal 2.
8 is transmitted to the ink jet printer 8.

The synchronization signal 28 is a synchronization signal generated when the rotation speed of the NC motor shaft of the NC turret punch press 14 is detected and the rotation speed becomes constant.
You. That is, a predetermined number of pulses are generated for one rotation of the NC motor shaft, and a synchronization signal 28 is generated when the synchronization of the pulses falls below a certain value. Alternatively, when the distance between the printing reference point 19 and the printing start position N becomes constant, a synchronization signal 28 synchronized with the rotation speed of the NC motor shaft is generated. Printing start position from printing reference point 19
Whether or not the distance to N is constant is determined, for example, by a counter having a count value corresponding to the distance, and counting down when the X-axis / Y-axis table of the NC turret punch press 14 moves by a predetermined amount. May be provided for detection. In this way, the inkjet printer 8 receives the print command signal 27 and the synchronization signal 28, performs synchronization control, and prints a character or a barcode on the processing material 1 based on the character string data.

[0033] Here, the synchronization control, in the case of detecting that the rotational speed of the NC motor evening axis becomes constant, since the moving speed of the processing material 1 is constant, the constant intervals by the ink jet printer 8 Printing is performed by jetting ink.
When detecting the distance from the printing reference point 19 to the printing start position, the inkjet printer 8 ejects ink in synchronization with the rotation speed of the NC motor shaft. Whether the printing of all the character strings is completed is confirmed by outputting the status confirmation signal 21 sequentially by the computer 15, and the printing of all the character strings is completed. When the printing of all the character strings is completed, the movement of the processing part for printing by the NC turret punch press 14 is stopped. By repeating such an operation, a plurality of printings on the processed material 1 are completed. Next, by processing the processed data by the NC device 13 N
Processing is performed by a C turret punch press 14 .

In the above, the case where the printing corresponding to a plurality of processing parts is completed on the processing material 1 and the processing is performed after that has been described. However, the processing is performed first, and then each processing part is processed. Printing can be performed, and printing and processing can be repeated for each processed part. These can all be performed by the procedure for creating the NC data program.

The NC unit 13 performs program end data processing, and the sequencer 16 receives the program end signal to end the processing, and the computer 15 receives the processing end signal to end the system.

Next, control of the arm turning of the ink jet printer will be described. FIG. 6 is a configuration diagram of the turning reverse turning control device of the ink jet printer. 30 ink tank 31 is an ink jet printer having a non-contact printing function 32 holds the ink jet printer 31

Let it. Therefore, the ink jet 31 can be moved with less vibration and impact.

In the above, the case where printing corresponding to a plurality of processing parts is performed on the processing material 1 and the processing is performed after that has been described. Conversely, the case where the processing is performed on the processing material 1 and then printing is performed will be described. The processing and printing can be performed in the same manner by first storing the processing data in the storage order of the data shown in FIG. 2 and storing the printing data with the reference positioning position of each processing component as the origin. In addition, although the NC turret punch press is used for the processing of the processing material 1, a conventionally known laser processing machine may be used.

In addition, since it is difficult to see the ink-jet printing on the metal surface, a seal having a reflectivity different from that of the metal surface as much as possible is attached to the metal surface, or a laser beam for material processing whose output is reduced by applying white paint or the like is printed. If you hit it instead of the inkjet, you can print because the background of the material is visible through the area where the laser hits. This eliminates the need for separately providing an ink jet device.
