Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a logistics management device using a work-in-progress location code for managing the lot processing progress of a plurality of processing devices using a microcomputer.

[Conventional technology]

A conventional device of this type is shown in FIG. In the figure, %1 is the processing device A, 2 is the processing device B, 3 is the processing device C14 is the distribution management device, 5 is the CRT, 51 is the keyboard, 6 is the processing device 1.2.3, and the distribution management device 4. It is a communication line that connects the

Further, FIG. 6 shows a group of physical distribution management tables.

In the figure, 11 is a device definition file, and 12 is a progress file.

Next, the operation will be explained. First, the input lot Nl is input by operating the keyboard 51 on the CRTS shown in FIG. 5 using the CRT screen shown in FIG.

This operation causes the physical distribution management device 4 to receive a start command (G
O) is given to, for example, the processing device A1 via the communication line 6. At this time, "lot number" and "equipment name j (in this case, processing equipment person) are registered in the empty record of progress file /I/12 in FIG. 6, and the above record number is registered in equipment definition file N11. be done.

The logistics situation at this time is displayed on the screen on the CRTS as shown in FIG.

[Problems that the invention helps solve]

The conventional logistics management system uses in-process location codes.

Since the system is configured as described above, there are problems in that only the work in progress for each device can be displayed, and detailed and overall logistics information cannot be displayed even though it is necessary.

This invention was made in order to solve the above-mentioned problems, and aims to provide a logistics management device using in-process location codes that can perform physical distribution management using in-process location codes and display in-process locations on a CRT. shall be.

[Means for solving problems]

The logistics management device using the in-process location code according to the present invention includes:
In order to understand the processing status of lots in each processing device in detail, we perform management using in-process location codes, and
This allows the distribution status of lots to be displayed on a CRT.

[Effect]

The physical distribution management table in this invention is stored in advance in a RAM (memory) that is accessed by the microcomputer, and is updated in accordance with the progress of the lot.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. The system configuration of the physical distribution management device is the same as the conventional example shown in FIG. 5, so a description thereof will be omitted.

Figure 1 shows a group of logistics management tables. In the figure, 11
is a device definition file, 12 is a progress file, 13 is a device in-process configuration file, and 14 is a device in-process file. Further, FIG. 2 shows a list of in-process codes, and FIG. 3 shows a distribution status display screen on a CRT5.

Next, the operation of this invention will be explained. The procedure of the processing operation is shown in the flowchart of FIG.

First, while looking at the CRT 5 from the keyboard 51 and referring to the lot input screen shown in FIG. 7, input the lot (lot) Nu large input ST-1) from the CRT. Then, the lot loading process S1 from the CRT shown in FIG. 4 starts.

In the lot input process S1 from the CRT, first.

Lot information is registered in the empty record of the progress fan 12 shown in FIG. 1 (ST-2). Next, the corresponding record of the device definition file 11 is extracted from the device name (ST-3). Then, from the contents of the record, the first record Ni1 (LRN) of the in-process configuration file 13 and the number of records following it are determined and processed. The record with the work-in-process location code of □ is taken out (5T-4). Then, extract the first record N1 (LRN) of the device in-process file and the number of records following it from the retrieved record, and extract the corresponding record (from the first record ⇒ to (the number of first record part child records - 1) of the device in-process file. (between), if there is an empty record, register the records (progress FLRN) of the progress file F in the equipment in-process file N14 (ST-5, 5T-6) 0 By managing the empty records in the equipment in-process file N14, the same By limiting the number of lots with a work-in-progress location code and checking the maximum number of work-in-progress, it is constantly checked to ensure that distribution is carried out smoothly.

When all the above processes are completed, a Go command is finally output to the corresponding processing device through the communication line 6 (ST-7).
As a result, the lot loading process S1 from the CRT ends. Subsequently, the processing device A that received the GO command,
B, C11, 2, 3 start processing, event) ST%
PR and ED commands (see Figure 2) are transmitted in sequence. When the physical distribution management device 4 receives the above-mentioned command, a command receiving process S2 from the processing device shown in FIG. 4 starts operation.

In command reception process S2 from the processing device, first, the command receiving device name and lot m are taken out (ST-8
). Then, extract progress file 12 from Lot Ugly,
Check whether the device section in the extracted record matches the receiving device name (ST-9, 5T-10). Also, when the received command has a valid in-process location code, each event) ST
, PR.

It is checked that the in-process code IQ11QQ1jPO1 corresponds to ED (ST-11).

Next, a primary work-in-process location code is obtained from the current work-in-process location code (ST-12). Then, find the next work in progress location (ST-12) and Iol is Q. To □, Qo is to P0□,
Po1 moves the in-process location code to O8.

Then, it is checked whether there is an empty record in the record on the device in-process file corresponding to the next in-process location code (ST-13). And if there is a free record,
Move the record of the original equipment in-process file (the record corresponding to the current in-process location code) from the previous position to an empty record (ST-14), place an empty record mark in the original record position, and make it an empty record. .

Then, the in-process location code in the progress file 12 is rewritten as a new one (ST-15).

〔Effect of the invention〕

As described above, according to the present invention, the distribution system is configured such that the distribution management table of the distribution management device can be constantly managed for each in-process location code.

Detailed logistics management can be realized using in-process location codes, and the in-process status of each processing device can be confirmed from a CRT.
