Based on the working slip format file, a working slip is issued.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an automatic work slip issuing system, and particularly to a system that communicates with an in-factory production control system.

[Background Art] An in-factory production management system is a system that contributes to the management and automation of manufacturing of devices such as LSIs that are manufactured through complex and diverse manufacturing processes.

For example, a terminal device is placed in each pay (unit section of the factory) of an LSI factory, and the manufacturing progress of each lot and the conditions of each process and each device are managed through communication between this terminal device and a host computer.

On the other hand, in factory production, work slips are generally essential for instructing workers on the content of work.

This work slip has conventionally been issued by, for example, a personal computer, a word processor, or the like.

FIG. 3 shows the flow of conventional work slip management as a system relationship.

The second diagram shows an input planning system 10 that plans and manages inputs for production in each factory, a work slip issuing system 12 that issues work slips in response to requests from this input planning system 10, and a work slip issuing system. An in-factory production management system 14 that manages actual production within the factory based on work slips issued by 12 is shown. Furthermore, the in-factory production management system 14 is installed in each of the plurality of factories.

That is, the in-factory production management system 14 manages the progress of each lot and process conditions (recipes) of each process in its own factory.

FIG. 4 shows the configuration of the work slip issuing system 12 as a flowchart.

In this diagram, first, the work flow recipe for each process -
is determined (100).

Next, a sample slip is created in a predetermined format using a word processor (102).

Sample slips created in the prescribed format are stored on floppy disks or as original documents (
104).

After this, the system operator determines whether there is an input plan (106). If there is no input plan, the process returns to step 104 and the process is repeated.

Specifically, in the determination 106, the following operations are performed. In other words, the request from the input planning system 10 (
If there is a trigger), it is determined in decision 106 that there is an input plan, and the process moves to the next step 108. The input planning system 10 is a system that determines an input plan for each factory, and based on this input plan, it issues a trigger and determines work information related to input lots, so-called lot information.

Step 108 is not performed by the device of the work slip issuing system 12, but is performed manually. That is, the operations before step 104 are executed by, for example, a personal computer or a word processor, but steps 106 to 110 are performed manually by the operator. In step 108, the work slip is issued by copying the sample slip created in step 102 and stored in step 104, cutting and binding the copy, entering information such as input date and time, shipping date, etc. on the slip, checking the entered contents, etc. This is done by an operator of the system 12, such as a word processor operator. The work slip created in this way is provided to each process in step 110. That is, this work slip will be issued to the in-factory production management system 14 at the same time as input.

[Problem to be solved by the invention] As described above, in the past, much manual work was required in the work related to issuing work slips, and issuing work slips required a long time and required an excessive amount of man-hours. There was a problem that

In particular, it takes a lot of time to copy sample slips.
Also, errors in this copying can often occur. Furthermore, mistakes are likely to occur in the contents entered on the work slip, and in these cases, additional time and man-hours are required to issue the work slip for correction. In addition, in the event that additional corrections or input errors occur when modifying the contents of a work slip, management is needed to appropriately eliminate such corrections or input errors, but the work slip issuing system This was difficult because it was constructed using a personal computer or word processor.

The present invention was made with the aim of solving these problems, and it realizes the connection between the input planning system and the in-factory production control system by exchanging information, and automatically issues work slips. The purpose of this invention is to provide an automatic work slip issuing system that makes it possible to do this.

[Means for Solving the Problems] In order to achieve such an object, the present invention supplies model information such as work conditions and flow of each process to an in-factory production management system and stores it in a database. , Lot information, which is a column of model names determined for each lot according to the input plan, is imported from the input planning system for each lot, and the model information is imported from the database and merged with the lot information to perform a series of operations corresponding to each lot. generate work information indicating the contents of the
Apply this work information to a predetermined format, create a work slip format file on the database,
A feature is that a work slip for each lot is issued based on this work slip format file.

[Function] In the automatic work slip issuing system of the present invention, first,
Model information is stored in a database and merged with lot information from the input planning system. As a result, work information indicating a series of work contents corresponding to each lot is generated.

Furthermore, this work information is applied to a predetermined format, and a work slip format file is created on the database. Furthermore, a work voucher for each lot is issued based on this work voucher format file.

[Examples] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

Components similar to those of the conventional example shown in FIGS. 3 to 4 are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 1 shows the flow of work slip management using an automatic work slip issuing system according to an embodiment of the present invention.

In this figure, a work slip system 16 is connected to an input planning system 10, and the automatic work slip issuing system 16 has a built-in database 18. In addition, the automatic work slip issuing system 16 is the in-factory production management system 1.
The in-factory production management system 14 has a built-in database 20.

FIG. 2 shows the configuration of the automatic work slip issuing system 16 according to this embodiment as a flowchart.

In this figure, after the work flow and recipe-1 model name is determined (100), information regarding this model name is stored in the database 20 (112).

In other words, since the in-factory production management system 14 requires model name information for production management in the art factory, the model name information shared with the work slip automatic issuance system is stored in the database 2.
It is stored as 0.

Furthermore, after this storage 112, the model name information is stored in the database 18 built into the automatic work slip issuing system 16 (114).

After this, it is determined whether there is an investment plan. (106).

This determination is made in response to a trigger from the input planning system 10. If there is no input plan, the process returns to step 114 and repeats the process, and if there is, the next step 1 is performed.
16. However, in this example,
Unlike the conventional example, the trigger is supplied from the input planning system without human intervention. In other words, input planning system 1
0 and the work slip issuing system 12 are connected, the trigger is directly input from the input planning system 10.

In step 116, based on the lot information supplied from the input planning system 10 and the model name information read from the database 20, a process of merging these pieces of information is performed. The merged information is work information indicating the contents of a series of works for each lot, and a work slip format file in a predetermined format is created on the database 18 based on this work information. Then, a work slip is issued based on this work slip format file.

After this, the issued work slip is cut and bound (11
g) will be provided into the process by step 110.

In this way, in this embodiment, the issuance of work slips is automated, so the number of man-hours required for issuing work slips is reduced compared to the conventional method. In other words, the manual operations (7)-4, such as copying sample slips and checking filled-in contents, are no longer necessary, and the time required for these operations is reduced.

Furthermore, for the same reason, errors in creating work slips are reduced. For example, mistakes in copying sample slips and mistakes in filling in work slips are significantly reduced.

Since the work slip is managed as a work slip format file, management is easier than in the past.

[Effects of the invention] As explained above, according to the present invention, the issuance of work slips is automated, which reduces the time and man-hours involved in issuing work slips, and improves the accuracy of creation, such as reducing creation errors. improve,
Furthermore, management of work slips becomes easier.
