In the processing factory B, when the base material 1 sent from the base material manufacturing section enters the warehouse, the operator operates the scanner 4a.
The bar code of the product card 2 of each base material 1 is read. The master computer 4 compares the barcode with the storage schedule information, and if the base material 1 of the barcode is the base material 1 to be stored, stores data indicating the type of the base material 1 as inventory information. I do.

On the other hand, when data relating to an order for a product is transmitted from a trading company or the like to the master computer 4 via a telephone line or the like, the master computer 4 transmits the ordering information, the specified thickness of the product, Order contract information is created and stored based on pre-stored information about the product such as width, length, and number of packages. Then, when the operator inputs an instruction of the processing content on the production line a based on the order contract information, the master computer 4 displays the product number of the base material 1 suitable for processing the product and the like. Since the displayed base material 1 is displayed in some cases more than the number of base materials 1 necessary for processing, the operator appropriately selects the base material 1 to be processed from these base materials 1. And input the number of processed sheets.

Then, the master computer 4 determines the product number of the base material 1 to be processed, the trimming amount of the side edge of the base material 1,
The cutting width of the base material 1, the shear dimension of the base material 1, and the like are stored as processing instruction information, and a processing instruction sheet displaying the contents of the processing instruction is output. The processing instruction includes a barcode for specifying the content of the processing instruction.

In the processing preparation step E, the data such as the product number of the base material 1 to be processed is
It is downloaded from the master computer 4 and stored. Then, the operator sequentially reads the barcodes of the product card 2 of the base material 1 placed in the storage place C with the hand scanner 8. The hand scanner 8 compares the read barcode with the stored product number of the base material 1 and determines whether the base material 1 of the read barcode corresponds to the base material 1 to be processed. Then, when it is determined that it is applicable, the worker is notified by voice or the like. Then, the worker
The base material 1 is set on the uncoiler section a1 of the production line a. When there are a plurality of base materials 1 to be processed, the hand scanner 8 displays the order in which the base materials 1 are set in the uncoiler section a1 of the base material 1 on the display 8f. Set in the uncoiler section a1.

On the other hand, in order to start the processing after the processing preparation step E, when the operator reads the bar code of the processing instruction with the scanner 7a, the processing instruction is displayed on the display section 7b of the operation panel 7 of the production line a. All the contents of the processing instruction corresponding to the letter are displayed. After the operator confirms the contents of the processing instruction on the operation panel 7, the operator operates the operation unit 7 c of the operation panel 7, so that the contents of the processing instruction are stored in the cutting processing part a 3 and the shearing part a 4 of the production line a. The processing conditions such as the cutting width and the shear size of the base material 1 are set in accordance with the conditions.

Next, the operator reads the bar code of the product card 2 of the base material 1 set in the uncoiler section a1 by the scanner 7a. Note that a list of the base materials 1 to be processed is displayed on the display unit 7b of the operation panel 7. If the read barcode corresponds to the base material 1 for which processing has been instructed, the correct base material 1 is set, so that unwinding of the base material 1 is started and the cutting process A is started. I do. The master computer 4 stores the unwinding start time of the base material 1 and measures the time from the unwinding start time until the end of the base material 1 reaches the shearing portion a4 to calculate the operating rate. I remember. This operating rate can be displayed on the display unit 4f or printed out.

In the pile section a6, when a predetermined number of finished products are stacked on the pallet 3, they are automatically replaced with empty pallets 3. At this time, the operation unit 7 of the operation panel 7
When c is operated, the master computer 4 outputs two new product cards 2. This new product card 2
The product card 2 has a barcode obtained by adding a branch number to the barcode of the product card 2 attached first. The two new product cards 2 are attached to, for example, stacked and packed products.

If a defective part such as a scratch is found in the product in the inspection section a5, the product is a reserved product that needs to be reworked. The bar code on the card 2 is read by the scanner 7a. Then, the master computer 4 outputs the product card 2 on the hold display. The product card 2 displayed on hold is provided with a barcode obtained by adding a branch number to the barcode of the new product card 2 and is pasted on a reserved product. The reserved product is discharged from the inspection unit a5, is reworked, and becomes a product after re-examination. The inspection unit a5 is provided with a plurality of button switches for inputting the type of defect such as a scratch. The master computer 4 determines the type of the input defect, the time at which the defect occurred, and the number of cuts. The yield is calculated based on the ratio of the output of the product card 2 on hold display to the product. The master computer 4 transmits a report of the processing contents such as the yield to the trading company of the ordering party.

At the time of product release after processing is completed, an operator inputs a release instruction to the master computer 4 based on order contract information and the like. The master computer 4
Based on the contents of the exit instruction, exit instruction information is created and stored, and an exit instruction is output from the exit instruction information. The master computer 4 downloads and stores data such as the product number of the product to be delivered to the hand scanner 8.

Then, the worker operates the hand scanner 8.
Then, the barcode of the product card 2 of the product stored in the product place D is read. The hand scanner 8 compares the read barcode with data such as the product number of the stored product to determine whether the product of the read barcode corresponds to the product to be delivered, If it is determined that the situation is applicable, the worker is notified by voice or the like. The operator assembles products to be delivered to each destination. After that, when loading products on trucks,
The bar code of the product card 2 of the product is read by the scanner 7a, and it is confirmed again whether the product corresponds to the product to be delivered. One of the two product cards 2 affixed to the product is removed by the time of delivery and used for shipping management. The master computer 4 stores the data of the product at this time as shipping results, and outputs a delivery note, an invoice, and the like based on the data.

On the other hand, the product card 2 of the base material 1 stored in the storage location C and the work in process prepared on the entry side of the cutting process A by the hand scanner 8 at predetermined intervals such as every month. Card 2 and product place D of base material 1
The bar code of the product card 2 of the product placed in the PC is read, and the data of the bar code is uploaded to the master computer 4. The stock information of the master computer 4 is adjusted based on the delivery information and the like, and the master computer 4 checks the barcode data read every predetermined period and, if there is a difference, prints the difference, for example, by printing. Out. The master computer 4 transmits the stock information to a trading company or the like of the order destination. Further, the master computer 4 creates a base material balance table for managing the storage and the stock of the base material 1 based on the storage schedule information, the stock information, and the like, and transmits the table to the base material manufacturing unit.
