Further, the communication terminal 300 is not limited to the portable terminal, and may be a stationary terminal.

Next, the outline of the manufacturing control system 1 will be described. First, a process of manufacturing a metal stamped part by the equipment control device 200 will be described. When the equipment control device 200 receives a signal from the manufacturing control device 100 to start the operation of the press machine 440, the equipment control device 200 starts the operation of the press machine 440 to manufacture the metal stamped parts. A die is attached to the press machine 440, and a material such as metal (material to be processed) is sandwiched between the dies, and the material is pressed against the surface of the die by vertical movement with a strong force.

When the equipment control device 200 detects that the metal press parts have been ejected from the press machine, the equipment control device 200 reads out a code including individual identification information from the table stored in the auxiliary storage unit 230, and the laser printing machine 480 reads the surface of the metal press parts. A code containing individual identification information is attached to. Here, the individual identification information is a character string or a number unique to the metal stamped part, which is used to distinguish the manufactured metal stamped parts from each other. In the present embodiment, a code obtained by converting individual identification information into a two-dimensional code is attached to a component. As the two-dimensional code, for example, a QR code (registered trademark) can be used. However, the individual identification information is not limited to the two-dimensional code, and may be a one-dimensional code. Further, it is preferable that the two-dimensional code is engraved on the part so that the two-dimensional code does not easily disappear. In the present embodiment, as a method for engraving a two-dimensional code, a method of scraping the surface of a component by irradiating a laser with a laser printing machine 480 will be described, but the embodiment of the present invention is not limited to this. As a method for engraving the two-dimensional code, for example, a metal stamped part may be partially oxidized, or electrochemical etching may be used.

FIG. 2A shows a state in which a two-dimensional code 501 including individual identification information is attached to the surface of a metal stamped part. FIG. 2A shows a state in which the two-dimensional code 501 is attached to the upper surface of the metal stamped component, but the two-dimensional code 501 may be attached to the side surface or the bottom surface of the metal pressed component. Later, the two-dimensional code 501 may be attached to any position of the metal stamped component as long as the two-dimensional code 501 can be read.

Next, the equipment control device 200 measures the dimensions of the metal stamped parts in the measuring unit 430. In the present embodiment, height, distance, inner diameter, outer diameter, angle, and geometrical tolerance are acquired as dimensional data (also referred to as first data) of the metal stamped part. The dimensional data measured by the measuring unit 430 is associated with the individual identification information and stored in the auxiliary storage unit 230. After that, the equipment control device 200 transmits the individual identification information and the dimensional data to the manufacturing control device 100.

The manufacturing control device 100 reads dimensional data from the product management DB and determines whether or not the metal stamped part is a non-defective product. When the manufacturing control device 100 determines that the dimensional data of the metal stamped part is within a predetermined range, the manufacturing control device 100 determines that the metal stamped part is a non-defective product. Further, when the manufacturing control device 100 determines that the dimensional data of the metal stamped part is not within the predetermined range, the manufacturing control device 100 determines that the metal stamped part is a defective product. The determination result of the dimensional data may be stored in the product management DB. When the determination result of the dimensional data is stored in the product management DB, if it is determined that the dimensional data is within the predetermined range, 1 is stored as the determination result in the product management DB, and the dimensional data is within the predetermined range. If not, 0 is stored as a determination result.

When the manufacturing control device 100 determines that the dimensional data of the metal stamped parts is not within the predetermined range, the manufacturing control device 100 outputs a signal for stopping the drive device to the equipment control device 200. In the present specification and the like, the dimensional data determined not to be within the predetermined range is described as abnormal data. After that, the manufacturing control device 100 reads predetermined dimensional data from the product management DB and executes the analysis of the dimensional data. By analyzing the dimensional data, it is estimated which part of the equipment control device 200, which part of the press machine 440, or which part of the die has an abnormality. As a result, for example, the display unit of the manufacturing control device 100, the display unit of the equipment control device 200, and the like can display the equipment in which the abnormality has occurred, the abnormality data, and the candidate fixed phrases indicating the cause of the abnormality in the dimensional data. , Displayed on the display unit of the communication terminal 300.

A user who confirms a candidate fixed phrase that causes an abnormality in dimensional data in any of the display unit of the manufacturing control device 100, the display unit of the equipment control device 200, and the display unit of the communication terminal 300 is the equipment. In the control device 200, maintenance of the press machine 440, the mold provided in the press machine 440, the press peripheral device 460, and the like is performed. After the maintenance is completed, the user transmits a signal from any of the manufacturing control device 100, the equipment control device 200, or the communication terminal 300 to the manufacturing control device 100 to release the signal for stopping the drive device.

For example, by acquiring the QR code (registered trademark) affixed to the mold, the identification information of the mold can be acquired. The identification information representing the mold attribute, the equipment attribute, the material attribute, and the worker attribute may be acquired from the two-dimensional code or the bar code. Once the identification information of the mold, equipment, material, and worker is acquired, the same identification information is acquired as operation data until the identification information is updated.

Further, the identification information representing the worker attribute may be acquired by biometric authentication such as face, fingerprint, iris, vein, or voiceprint. For example, when the identification information representing the worker attribute is acquired by face recognition, the face information of the worker is acquired by the image pickup device (camera) of the communication terminal 300 before the equipment control device 200 is operated, and the face is acquired. Acquire identification information representing worker attributes based on the information. After that, the communication terminal 300 transmits the identification information representing the worker attribute to the equipment control device 200.

The biometric authentication is not limited to that of the communication terminal 300, and may be connected to the equipment control device 200 by wire or wirelessly.

For example, when the press select switch is in the continuous mode and the press clutch is in the ON state, the press machine 440 is operating in automatic operation. When the press machine 440 is operated by automatic operation, the equipment control device 200 acquires the signal of the press machine 440, the signal of the detection unit 420, the signal of the press peripheral device 460, and the attribute data every second.

The equipment control device 200 acquires the operation data acquired when manufacturing the metal stamped parts when acquiring the individual identification information and the dimensional data corresponding to the metal stamped parts. The operation data acquired by the equipment control device 200 is associated with the individual identification information and stored in the auxiliary storage unit 230. After that, the equipment control device 200 transmits the acquired operation data to the manufacturing control device 100.

The operational data is not limited to these items, and may include at least one of these items. In addition, the operational data may include items other than these items. In FIGS. 4B and 4C, the press stop code corresponds to the sensor number provided in the die. In FIGS. 4B and 4C, the individual identification number press stop code 3 indicates that the sensor No. 3 provided on the die has detected an abnormality.

The manufacturing management device 100 acquires operation data from the equipment control device DB 132 at a predetermined timing, and determines whether or not the acquired operation data satisfies a predetermined standard. When the manufacturing control device 100 determines that the operation data does not satisfy a predetermined standard, the manufacturing control device 100 outputs a signal for stopping the operation of the drive device in the facility control device 200, assuming that some abnormality has occurred in the facility control device 200. Here, the operation data determined not to meet the predetermined criteria is described as abnormal data.

The master data is the production instruction No. It is the data in which the material code used (or the identification information of the material used), the mold code used (or the identification information of the mold used), the worker code and the identification information thereof, etc. corresponding to the above are defined. Further, as master data, a worker code (or worker identification information) certified for the target work is stored. As a result of collating the operation data acquired from the equipment control device DB with the master data, the manufacturing control device 100 sends a signal to the equipment control device 200 to stop the drive device when the acquired operation data is different from the master data. Output. For example, when the identification information of the material used in the operation data acquired when the target product is produced is different from the identification information of the material used in the master data, the manufacturing control device 100 attaches a drive device to the equipment control device 200. Output a signal to stop. For example, when the identification information of the mold used in the acquired operation data is different from the identification information of the mold used in the master data, the manufacturing control device 100 outputs a signal to the equipment control device 200 to stop the drive device. .. For example, when the worker code of the acquired operation data is different from the worker code of the master data, the manufacturing control device 100 outputs a signal to the equipment control device 200 to stop the drive device. As a result, the production instruction No. On the other hand, it is possible to prevent the wrong use of molds and materials and the work by workers who are not certified for the target work. Further, the manufacturing control device 100 analyzes the operation data to obtain the production instruction No. The correct material code used, mold code used, and worker code may be estimated for.

In the equipment control device 200, while the drive device is in operation, for example, whether the material feed position is correct, the product is placed in the correct position, or the product is discharged correctly based on the signal input from the detection unit 420.

As a result of the analysis by the analysis unit 1335, a fixed phrase of a candidate for the cause that the dimensional data of the metal stamped part does not fall within the predetermined range is output (step S410). A plurality of fixed phrases as candidates for the cause that the dimensional data of the metal stamped part does not fall within the predetermined range may be presented in order from the one with the highest possibility. The data output unit 1333 transmits a candidate fixed phrase that causes an abnormality in the dimensional data to the equipment control device 200 and the communication terminal 300.

When the drive equipment stop condition processing is started, the determination unit 1332 acquires operation data from the equipment control device DB 132 and determines whether or not the drive equipment stop condition is satisfied (step S421). If the determination unit 1332 determines that the acquired operation data does not satisfy the stop condition of the drive device when it matches the master data (step S421; No), the determination unit 1332 proceeds to the process of step S403. Alternatively, the determination unit 1332 determines that the stop condition of the drive device is satisfied when the acquired operation data does not match the master data. When the determination unit 1332 determines that the stop condition of the drive device is satisfied (step S421; Yes), the signal output unit 1336 transmits a signal for stopping the drive device to the equipment control device 200 (step S422). When the equipment control device 200 receives the signal to stop the drive device, the equipment control device 200 stops the press machine 440. Next, the analysis unit 1335 acquires at least abnormal data and analyzes it (step S423). As a result of the analysis by the analysis unit 1335, a fixed phrase of a candidate for the cause that the operation data does not meet the predetermined criteria is output (step S424). The data output unit 1333 transmits a candidate fixed phrase that causes an abnormality in the operation data to the equipment control device 200 and the communication terminal 300. Then, a candidate fixed phrase that causes an abnormality in the operation data is displayed on the display unit of the manufacturing control device 100, the display unit 140 of the equipment control device 200, and the display unit 140 of the communication terminal 300.

In the control device 200, maintenance of the press machine 440, the mold of the press machine 440, the press peripheral device, and the like is performed. After the maintenance is completed, the user transmits a signal from any of the manufacturing control device 100, the equipment control device 200, or the communication terminal 300 to the manufacturing control device 100 to release the signal for stopping the drive device. When the data receiving unit 1334 receives the signal for releasing the signal for stopping the drive device (step S425; Yes), the signal output unit 1336 transmits the signal for releasing the signal for stopping the drive device to the equipment control device 200. Then (step S426), the process proceeds to step S403. If the data receiving unit 1334 does not receive the signal for canceling the signal for stopping the drive device (step S425; No), the data receiving unit 1334 waits until the signal is received.
