Referring to Fig. 1, the system of the present invention uses a bar code medium 10 as shown in Fig. 2 as a production record information source. The barcode 12 of the barcode medium 10 includes a barcode related to year / month / day, a barcode related to shoe style / color / type, and the like when the barcode scanner 20 inputs the barcode 12. And an index bar code 14 or the like for preventing the same. It will be apparent to those skilled in the art that the bar code medium 10 according to the present invention shown in FIG. 2 is an embodiment of the bar code medium, and the arrangement of the index bar code 14 shown in FIG. 2 is not limited thereto.

The index barcode 14 prevents the barcode scanner 20 from repeatedly inputting the same barcode medium 10. The method generates an alarm when the barcode scanner 20 duplicates the same barcode medium 10. The data to be inputted or duplicated may be recognized as the same data, or the barcode data inputted to be duplicated may be processed as an error. The duplicated data may be recognized as the same data.

The bar code medium 10 as described above is an individual sole production process constituting the shoe production process, for example, a cutting process for cutting the shoe fabric into the shape of the upper part of the shoe, and an outsole for making a shoe bottom with raw rubber material. Used in individual unit production processes such as That is, when the work of the individual unit production process is completed and the result of the process is moved to the next process through packaging, or when it is received for another production process, or when the shoe is finally completed and shipped, it is attached to the packaging container surface. do. Here, in order to see the 100% effect through the construction of the present invention, it is preferable to standardize the packaging container and the packaging quantity by standardizing the packaging in each process to rectify the logistics flow.

When the individual unit production process is completed and the result of the process is packed in the packaging container (5) and the barcode medium (10) is attached to the packaging container (5), the operator finally ends the barcode medium attached to the packaging container (5). The barcode 12 of 10 is input to the barcode scanner 20. In some cases, the barcode 12 of the barcode medium 10 attached to the packaging container 5 received from the preceding individual unit production process is inputted to the barcode scanner 20 before the production process, or both when entering or leaving the factory. The barcode 12 of the barcode medium 10 attached to the packaging container 10 is input to the barcode scanner 20. As shown above, three examples of inputting the barcode 12 of the barcode medium 10 to the barcode scanner 20 are schematically illustrated in FIG. 3. Although shown in FIG. 3, the barcode medium 10 to be attached to the packaging container 10 is distributed by the production planning department, and the distributed barcode medium 10 is used in each individual unit production process. The bar code medium 10 to be distributed is manufactured so as not to overlap, and the index bar code 14 for preventing duplicate input of the bar code scanner 20 is added as described above. When the barcode medium 10 is manufactured, the barcodes are not duplicated. As an example of the method, the index barcode 14 is made of two hexadecimal digits and the number of kinds thereof is 1296. The probability of 10) is very low.

As described above, the input of the barcode according to the present invention is accomplished by the barcode scanner 20, which will be apparent to those skilled in the art that the barcode scanner 20 can use a commercially available barcode scanner. Of course, it will be apparent to those skilled in the art that the commercially available barcode scanner can be manufactured and used in a modified form using publicly known techniques.

The barcode data of the barcode medium 10 input by the barcode scanner 20 is registered and stored in the production process terminal 30, and the barcode data registered and stored as needed is transferred to another place. As shown in FIG. 2, the terminal 30 forms a unit with the barcode scanner 20 and is installed in each individual unit production process. The terminal 30 constituting the barcode scanner 20 acquires production information data generated in a timely manner in the individual unit production process through the barcode medium 10 in real time.

It will be apparent to those skilled in the art that the ID setting port 32 is included in the status plate 23 to perform the same function as that of the terminal 30. Although not shown, the ID is set through a predetermined selection switch, for example, a DIP switch, and the setting value is input to the central processing controller 39.

The barcode input unit 33 is for inputting external data, that is, barcode data into the terminal 30, and reads arbitrary level data through the barcode scanner 20. The output signal of the barcode scanner 20 is of RS232 level, and is converted into a TTL level signal through the RS232 communication unit 33a of the terminal 30 and input to the central processing control unit 39.

The digital input unit 34 receives a digital signal in order to acquire data from an external mechanical device, determines the presence or absence of data according to the determination of high / low, and transmits it to the central processing controller 39. .

The display unit 35 acquires data from the outside and displays the contents of the data on a display medium, for example, an LCD. At this time, the information such as year / month / day / time is also displayed so that the operator can know the occurrence time of the event.

The chip select circuit 36 controls through chip selection the relationship between the external event occurrence and the execution of its own program when the central processing unit 39 cannot control everything at the same time. The contents controlled by the chip selection are the ID setting port 32, the digital input 34, the display 35, and the barcode input 33. Such control is set through some of the address lines of the 8031 (Intel CPU trade name), which is a microprocessor of the central processing controller 39, and one of the address lines controls ON / OFF of chip selection. do.

The RS485 communication unit 38 performs RS485 communication for transmitting the information of the data acquired from the terminal 30 to the line controller 50. In this case, the RS485 communication method is adopted in relation to the distance between the point where the actual terminal 30 is installed and the line controller 50. For this purpose, an RS485 communication element is configured in the terminal 30 so that the TTL level signal and the RS485 level are established. It converts the signal of.

Barcode data, that is, production performance information of the barcode medium 10 input by the barcode scanner 20 is displayed on the status plate 23 so that workers in the corresponding production process can recognize it. The production record information displayed on the status board 23 is made by the control of the line controller 50 and the like described later. In addition to the production performance information, the status board 23 also displays the status of work in progress and the status of defects, etc. This enables smooth logistics movement, thereby improving productivity, and immediately knowing the status of defects, thereby preventing excessive defects. have.

The status board 23 also has a configuration similar to the terminal 30 described above as a kind of terminal, which is schematically illustrated in FIG. 5.

PULL-UP and input to BUS DRIVER TRANSCEIVER (not shown).

The display voltage level up circuit section 23c raises the voltage level when the drive voltage of the display medium is 12 volts instead of 5 volts, since the output level from the bus driver transceiver is TTL. That is, the display voltage level-up circuit unit 23c serves to raise the high voltage when the input voltage is low.

The display output circuit section 23d adjusts using a resistor RISESTER for proper light emission of the display media from the output signal of the display medium voltage level-up circuit section 23c when data is output from the central processing control section 39 'to the display media. Connect one-to-one lines to each pin of the display medium. Since the display medium FND currently used is an emitter common method, the level of the display medium output pin is only possible when the signal is high. However, it will be apparent to those skilled in the art that the display medium FND is enabled even when the signal is low.
