Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a physical distribution management method capable of preventing an erroneous shipment of a coil product, a plate material, etc. produced in a steelmaking factory by a vehicle.

[0002]

2. Description of the Related Art In a steel manufacturing plant, vehicles such as trailers and pallets are used to carry out produced steel products (coil products, plate materials, etc.) from a building. Equipment such as cranes and forklifts are also used for loading and unloading products on this vehicle.

Further, when carrying out from the building, shipping is carried out after checking the loaded actual product and the ledger, and only when all are in agreement, the driver is instructed to operate and the erroneous shipping is prevented. ing. Conventionally, this collation processing is all performed manually.

For example, a large number (for example, the last 3 digits) of a product number is written on a piece of paper and affixed to the actual product, and the operator can visually recognize the number or directly visually recognize the product number label. Then, the check is performed by matching with the ledger.

[0005]

However, since the conventional checking method is performed manually, there is a problem in that erroneous shipment due to misreading, omission, etc. may occur and customer credibility may be deteriorated.

An object of the present invention is to provide a physical distribution management method capable of preventing erroneous shipment due to human labor.

[0007]

In order to achieve the above object, the present invention collects the actual results of each loaded steel product with a crane terminal or the like in advance when loading and transporting a plurality of steel products on a trolley. Based on this record, the loaded steel product information is transmitted to the mobile terminal device, and this is compared with the reading result of the bar code label pasted on the coil in advance by the mobile terminal device, and the vehicle operation instruction is given depending on the suitability. I'm trying to do.

[0008]

According to the above means, the bar code previously printed on the steel product is read by the portable terminal device, and
It receives the actual results of steel products loaded on vehicles collected by crane terminals, collates them with the barcode reading results, and issues a vehicle withdrawal instruction from the collation results.
Therefore, shipping can be done without relying on human experience or intuition,
It is possible to prevent erroneous shipment.

FIG. 1 shows the functions or processes of the portable terminal devices 5a, 5b, 5c and the host computer 1 described above. In addition, S in the figure means a step.

The host computer 1 is provided with a vehicle loading product performance file 7 as shown in FIG. 3, a loading port management file 8 as shown in FIG. 4, and a vehicle operation work instruction file 9. The vehicle loading product result file 7 uses the vehicle number as a key (KEY) and sets the vehicle number (here, "12").
01 ”), the relationship between the product number and the check status is shown. Further, the shipping port management file 8 includes the vehicle statuses (1) to the shipping port number.
In the relationship of (n), “1” in the status column indicates that the vehicle has entered the building, “3” indicates that loading is in progress, and “9” indicates that loading is complete.

Each of the portable terminal devices 5a, 5b, 5c has a display screen made of liquid crystal or the like, and has a check product number table 10 and an error product number table 11. There are three types of screen display contents on the mobile terminal devices 5a, 5b, and 5c: a loading record request screen 12, a product number check screen 13, and a check result transmission screen 14.

Update between the portable terminal device 5a and the host computer 1 will now be described. In the portable terminal device 5a, by inputting the vehicle number on the loading record request screen 12, a request for the vehicle loading product number record (S10).
1) is transmitted to the host computer 1 via the connection device 4a and the optical loop network 3.

The host computer 1 reads out the data (vehicle loading product number) corresponding to the request from the vehicle loading product performance file 7 and sends it to the portable terminal device 5a (S102).

In the portable terminal device 5a, the data transmitted from the host computer 1 is stored in the check product number table 10, and the bar code of the steel product on the vehicle read by the bar code reader 6a and the content of the check product number table 10 are stored. (S103), and the check result at that time is displayed as the product number check screen 13 on the mobile terminal device 5a.
Is displayed on the display.

In this check processing, if the product number is correct, the check product number table 10 shown in FIG.
The error product number table 11 in (b) and (b) is referred to, and the presence or absence of a check is determined from the check completion status. The check result is displayed on the display as a product number check screen 13 (here, the product number is described as "Kembang") by reading the product number with the barcode reader 6a. It Also, when all the checks are completed, the check result transmission screen 14
By further inputting an instruction, it is transmitted to the host computer 1 via the connection device 4a, the optical loop network 3 and the transmission control device 2 according to the content shown in FIG. 6 (S10).

In FIG. 6, "0" in the check result column is the unchecked product number when there is no error product number, and "1" is the unchecked product number when there is an error product number. In addition, "0" in the status column indicates an unfinished check product number, "1" indicates an error product number, and "9" indicates a check OK product number.

When the product number is wrong, the product number is not found in the checked product number table of FIG. 7A, and therefore the error product number table is checked with the wrong product number as shown in (B). The completion status is filled in,
The product number check screen 13 as shown in (c) on the display
Is displayed as. In this case, “Mikan Kempusu (number of unfinished inspections)” changes from “003” to “002” in FIG. 5, and “Error Kempusu” changes from “000” to “0”.
01 ".

The host computer 1 receives the vehicle-mounted product number check result (S105), and determines whether the check result is unfinished or an error product number exists (S106). If there is, error information is output and the process ends, and if not, a vehicle withdrawal instruction is sent to the terminal device on the vehicle (S107).

The vehicle pull-out instruction is as shown in FIG.
Only when the check result is "0" (no check unfinished product number and no error product number), the vehicle withdrawal instruction is given, and the vehicle number "1201" is not given. Based on this vehicle pull-out instruction, the vehicle operation work instruction file 9 is updated as shown in FIG.

FIG. 10 is a flow chart showing the detailed processing of step 103 in FIG.

First, it is determined whether or not the input product number is in the error product number table (S1001). If there is, the product number is highlighted and the message "Already checked, product difference" is displayed. (S1002), and the processing after step 1007 is executed.

On the other hand, when it is determined in step 1001 that there is no input product number, it is determined whether or not the input product number is in the check product number table 11 (S1003).
If there is not, the product number is added to the error product number table 11, and "1" is added to the number of error product numbers and the number of checked product numbers (S1004). Then, the product number is highlighted and a "difference in product" message is displayed.

On the other hand, if it is determined in step 1003 that there is an input product number, it is determined whether the check completion status is incomplete (S1005). If it is not completed, the check completion status in the check product number table 10 is completed, "1" is added to the number of checked product numbers and the number of errored product numbers (S1010). Then, a message of "check OK" is displayed (S1011).

Step 1006 or step 1011
After processing [Number of checked product numbers ≧ number of loaded product numbers]
It is determined whether or not (S1007) is satisfied, and if the determination formula is satisfied, the number of loaded product numbers is displayed in reverse video and a "check completed" message is displayed (S100).
8).

If the check completion status is completed in step 1005, the product number is highlighted and the message "already checked, check OK" is output to the terminal (S1009), and the processing from step 1007 onward is performed. .
