Description

The present invention relates to a system for automatically issuing work slips, and more particularly, to a system for communicating with a production management system in a factory.

2. Description of the Related Art A factory production management system is a system that contributes to management and automation of manufacturing of devices manufactured through complicated and various manufacturing processes such as LSI.

For example, a terminal device is arranged in each bay (unit unit of the factory) of an LSI factory, and the exchange between the terminal device and the host computer manages the manufacturing progress of each lot and the conditions of each process and each device.

On the other hand, in factory production, generally, a work slip for instructing a worker on work contents is indispensable.

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

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

In this figure, an input planning system 10 for planning and managing input to production at each factory, a work slip issuing system 12 for issuing a work slip in response to a request from the input planning system 10, and a work slip issuing system 12 And a factory production management system 14 for managing actual production in the factory based on work slips issued by the company. The in-plant production management system 14 is installed in each of a plurality of factories.

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

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

In this figure, first, the work flow and recipe of each process are determined (100).

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

The sample slip prepared in a predetermined format is stored on a floppy disk or stored as an original (104).

Thereafter, 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.

In the determination 106, the following operation is specifically performed. In other words, when there is a request (trigger) from the input planning system 10, it is determined in the determination 106 that there is an input plan, and the process proceeds to the next step. The input planning system 10 is a system for determining an input plan in each factory, and issues a trigger based on the input plan and determines work information, that is, so-called lot information, for an equal input lot.

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 manually performed by the operator.
In step 108, a work slip is issued including copying the sample slip created in step 102 and stored in step 104, cutting and binding the copy, entering information such as the date and time of shipment and shipping date in the slip, and checking the contents of the entry slip. This is performed by an operator of the system 12, for example, an operator of a word processor. The work slip created in this way is provided to each step in step 110. That is, this work slip is issued to the production management system 14 in the factory upon input.

[Problems to be Solved by the Invention] As described above, in the related art, much manual work is required in the work related to the issuance of a work slip, and it takes a long time to issue the work slip and the man-hour is excessive. There was a problem that has become.

In particular, copying a sample slip requires a lot of time, and mistakes in this copy can often occur. Further, mistakes are likely to occur in the contents entered in the work slip, and in these cases, it takes more time and man-hours to issue the work slip for correction. In addition, in the case of further correction omissions or input errors when the contents described in the work slip are corrected, it is necessary to manage such omissions and errors appropriately. The system is difficult because it is composed of a personal computer or a word processor.

The present invention has been made with an object to solve such problems, and realizes connection between an input planning system and a production management system in a factory by transmitting and receiving information,
An object of the present invention is to provide a work slip automatic issuing system that can automatically issue a work slip.

[Means for Solving the Problems] In order to achieve such an object, the present invention supplies model name information such as work conditions and flow of each process to a factory production management system and stores it in a database. A series of operations corresponding to each lot, by taking lot information, which is a series of model names determined for each lot according to the input plan, from the input planning system and taking the model information from the database and merging with the lot information Generate work information indicating the contents of, and apply this work information to a predetermined format,
A work slip format file is created on a database, and a work slip for each lot is issued based on the work slip format file.

[Operation] In the work slip automatic 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. Further, the work information is applied to a predetermined format, and a work slip format file is created on the database. Further, a work slip for each lot is issued based on the work slip format file.

EXAMPLES Hereinafter, preferred examples of the present invention will be described with reference to the drawings.

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

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

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

FIG. 2 is a flowchart showing the configuration of the work slip automatic issuing system 16 according to the present embodiment.

In this figure, after a work flow, a recipe, and a model name are determined (100), information on the model name is stored in the database 20 (112). That is, the factory production management system 14 stores model name information shared with the work slip automatic issuance system in the database 20 because model name information is required for production management in the factory.

Further, after the storage 112, the model name information is stored in the database 18 incorporated in the work slip automatic issuing system 16 (114).

After that, it is determined whether there is an input 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 to repeat the process. If there is, the process proceeds to the next step 116. However, in the present embodiment, unlike the conventional example, the trigger is supplied from the input planning system without being obtained. That is, since the input planning system 10 and the work slip issuing system 12 are connected, a trigger is directly input from the input planning system 10.

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

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

As described above, in the present embodiment, the issuance of the work slip is automated, so that the man-hour required to issue the work slip is reduced as compared with the related art. That is, a series of manual operations such as copying a sample slip and checking the contents of entry are not required, and the time required for these operations is reduced.

Further, for the same reason, the number of errors in creating a work slip is reduced. For example, the mistake of copying the sample slip,
Mistakes in the work slip are significantly reduced.

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

[Effects of the Invention] As described above, according to the present invention, the issuance of work slips is automated, so that the time and man-hours involved in issuing work slips are reduced, and the accuracy of creation such as reduction of creation errors is reduced. And the management of work slips becomes easier.
