[Industrial application field]

The present invention relates to a design change instruction system in a manufacturing process.

[Conventional technology]

The items produced at various manufacturing plants are not necessarily constant, but are usually wide-ranging. Particularly in recent years, as consumer tastes and values have diversified, user specifications have been frequently changed and functions have been added, leading to frequent design changes.

Electronic circuits for various devices currently manufactured are created by mounting semiconductor devices such as ICs and many electronic components on printed I-boards, but they are created on the production line of such printed board units. Drawings for items include thousands or tens of thousands of drawing numbers.

However, not all of these are in production at all times; of these, for example, several thousand numbers are involved in monthly production.

In the computer-based process control system normally used in manufacturing departments, when the design of a manufactured item is changed as described above and a revised drawing is received, if the revised drawing is to be applied from a new start, There were no major problems, but if immediate application was required, it was not possible to issue a revision command on the computer to something that was in progress on the production line.

Therefore, when we receive revised drawings that require immediate application, we check whether the necessary parts and materials can be delivered based on the specified application period and revised content, and check the process progress of the parts by checking the actual product. After checking, if the parts delivery conditions were met, the work of deciding ``which loft'', ``when'', and ``which process'' to apply the revised drawing was done manually.

However, as mentioned above, a wide variety of In manufacturing items are in progress on the production line, so it is necessary to investigate how many of the parts are in which process, and to determine when it is possible to start work based on revised drawings. Making changes to work and manufacturing plans is very time-consuming and not always easy (as a result, there are problems such as delays in applying revisions instructed by the engineering department, and disruptions to parts procurement and production lines. Furthermore, if a part that has completed a certain process is pulled out of the official production line in order to carry out modification work based on revised drawings, the process may be delayed even though the process has actually been completed. The process is left uncompleted on the management system, temporarily disconnected from the computer-based process control system, and then completed only when the modification work is completed and the line returns. It was necessary to manipulate data in the management system.

[Problem to be solved by the invention]

As described above, with conventional process management systems, it is extremely difficult to deal with any changes such as design changes.

An object of the present invention is to provide a design change instruction system that allows revised drawings accompanying design changes to be quickly, reliably, and easily applied to manufacturing lines both inside and outside the company.

[Means to solve the problem]

The design change instruction system of the present invention has a progress file 1. Manufacturing condition master 22 drawing number/version number recording section 3゜ and registration means 4
．． Means for determining whether revision is necessary 6. Revision instruction means 8. A progress updating means 9 is provided.

If a design change instruction received from the engineering department requires immediate application, it is sent to the manufacturing condition master 2 via the registration means 4.
, the drawing number 14 of the revised drawing and its version number 15 are registered, and if immediate application is required, an immediate application flag 1 is set.
6 is registered.

On the other hand, when workpieces are introduced into the production line, a product identification card 5 recording the identification number of each workpiece is issued and attached to the workpiece. A manufacturing line usually consists of a plurality of manufacturing processes, and each time one manufacturing process is completed, the product identification card 5 of the workpiece is read. Based on the read identification number, the revision necessity judgment means 6 first refers to the figure number/version number recording section 3,
Check the current version number 18 of figure number 14 of the read work,
Next, the manufacturing condition master 2 is referred to based on the current version number of this drawing number, and depending on whether there is a version newer than the current version number of the drawing number 14 and the immediate application flag 16 is registered, an immediate revision is performed. Determine whether or not it is necessary.

If the immediate application flag 16 is registered and the revision necessity determining means 6 determines that an immediate revision is necessary, the revision instruction means 8 issues a revision command 7 to cause the work to be revised.
is issued, but the completion date is not entered, a status flag 12 indicating interruption is set in the progress file 1, and it is clearly indicated on the i-degree file 1 that the workpiece has been removed from the normal production line.

If there is no immediate application flag 16 and it is determined that no revision is necessary, the progress update means 9 sets a status flag 12 in the column of the corresponding process of the corresponding identification number in the progress file 1 to indicate that the process has been completed. Also, enter the completion date 13.

[Function] In this embodiment configured as described above, each process can be completed by registering the drawing number, its version number, and whether immediate application is required in the manufacturing condition master according to the received design change instructions. The manufacturing condition master is referenced at the time, and if immediate application is required, it is automatically detected and a revision order is issued. Therefore, there is no delay in application or omission of application, and design changes can be applied quickly and accurately.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, an example in which the present invention is applied to an assembly line for printed board units will be described below with reference to FIGS. 1 and 2.

In this embodiment, as shown in FIG.
．． Manufacturing condition master 21 drawing number/version number recording section 3 and registration means 4. Means for determining whether revision is necessary 6. Revision instruction means 8. In addition to the progress updating means 9, the operation console 21 is provided with line return processing means 22.

When assembling printed board units, necessary parts and materials are placed on the assembly line according to the drawings for each manufactured item. At this time, it is common to construct a loft using a certain number of units for each same manufactured item, and when the members constituting this loft are assembled and put into the assembly line, an item identification card 5 is issued and attached. Ru.

The item identification card 5 is called a work card or production instruction card, and is made of a magnetic card, magnetic stripe card, punch card, barcode label, IC card, etc. whose recorded contents can be read by a card league or the like. As shown in FIG.
In addition, various information necessary for manufacturing management 9, such as perfume and quantity 1 Drawing numbers used on the assembly line.

The edition number etc. are recorded.

This information is recorded on the magnetic stripe 25 or the like so that it can be read by a card league, and is also printed so that it can be read by humans.

When the design department issues an instruction to change the design, the manufacturing department issues the drawing number 14 and version number 15 of the drawing instructed from the operation console 21, as well as the immediate application flag if this revised drawing requires immediate application. Register 16.

This registration is carried out on a magnetic tape 2 containing information indicating the registered contents.
If the information is stored on a magnetic tape 23 and sent, the necessary information may be read from the magnetic tape 23.

The above-mentioned immediate application flag 16 may be registered by setting a predetermined bit to O or L, or by providing a flag registration area and writing, for example, "*" therein, in short, immediate application is possible. It is sufficient if it is possible to clearly identify whether or not it is necessary.

The figure number/version number recording unit 3 records the identification number of each lot for all the lots input into the manufacturing process: 11 degrees, the figure number 14 specified at the time of input into the manufacturing process, and the edition number (initial edition number) 17.
It consists of items such as 18 and the version number (current version number) corresponding to the current state. The current version number 18 may record a new version number only when it has been modified based on the revision command 7, or may always record the version number corresponding to the current state.

In this embodiment, the current version number 18 is always recorded.

Therefore, unless there is a revision during the process, the original version number 17 and the current version number 18 of that lot are the same.

This drawing number/version number recording section 3 may be provided as one independent file together with the progress file 1 and the manufacturing condition master 2, or may be provided as a part of the actual item identification card 5. In this embodiment, the above-mentioned items are provided on the item identification card 5.

The progress file 1 is a file that records the progress of each lot, and corresponds to the identification number 11 of each lot input into the manufacturing process, with 3 unstarted and 3 in progress for each process.

It is configured to record a status flag 12 indicating either interruption or completion and a completion date 13 of the process.

Each time a lot input into the manufacturing process completes one process, the item identification card 5 is read by a card league (not shown). In this embodiment, the identification number 11. from the actual product identification card 5. Figure number 14 of the drawing used. Original version number 1
7. The current version number 18 is read out and sent to the revision necessity determining means 6. This allows the current state of the lot to be grasped.

The revision necessity judgment means 6 refers to the manufacturing condition master 2 based on the drawing number 14 and the current version number 18 of the lot, searches for the same drawing number, and determines whether there is a newer version than the current version number 18 read above. Check whether the immediate application flag 16 is registered. If a version newer than the current version 18 exists and the immediate application flag 18 is registered, the version number is set to the above identification number 11, figure number 14, and current version 18.
It is also transferred to the revision instruction means 8.

Based on the transferred information, the revision instruction means 8 issues a revision instruction 7 for the lot, and does not enter the completion date 13 in the corresponding process of the identification number 11 in the progress file 1, indicating an interruption. A status flag 12 is registered to clearly indicate that the modification work has been extracted from the normal process (hereinafter referred to as line-out).

For example, the status flag 12 is 0.1.2 and 3.
It is sufficient to correspond to unstarted, in progress, interrupted, and completed, respectively, and by recording any of these,
It can show the current status of the lot. That is, when extracting from the normal process to perform the above-mentioned revision work, the status flag 12 is set to "2" to indicate that the normal process has been temporarily interrupted.

When the above-mentioned revision order 7 is issued, the loft concerned is lined out and sent for modification work, and the modification work is carried out according to the "number of repair versions" instructed in the revision order 7.

When the modification is completed, the actual product identification card 5 is run through the card league again to read the identification number 11 and the like, and is sent to the line return processing section 22. The line return processing unit 22 detects that the above-mentioned status flag 12 is interrupted in the process record of the identification number 11 in the progress file 1.

In other words, the ``2'' is rewritten to ``3'' indicating completion, and the completion date 13 is written to update the progress file 1.The line-out status of the loft is now released and the regular manufacturing status is confirmed. The line returns to the process.

As described above (in this embodiment, the progress file cannot be updated in the line-out state, but when the line returns, the progress can be updated again).

When the line return processing is performed in this manner, the line return processing section 22 simultaneously updates the current version number 18 in the drawing number/version number recording section 3 to clearly indicate the current state of the loft.

If the revision necessity determining means 6 determines that immediate revision is not necessary, the progress updating means updates the progress of the lot. In this case, the loft is sent to the next process as usual.

As explained above, in this embodiment, when a revised drawing for a design change is issued by the engineering department, the drawing number of the revised drawing, its version number, and whether immediate application is necessary are registered in the manufacturing condition master 2. By referring to the manufacturing condition master 2 when updating the progress, it is possible to automatically and completely detect whether immediate revision is necessary for each lot at the end of each process. Therefore, unlike in the past, there is no need to manually inspect the actual product one by one (not only does this eliminate unnecessary labor, but it also eliminates the risk of delays in the expiration date or omissions in application).

〔Effect of the invention〕

As explained above, according to the present invention, design change application instructions are connected online to the process management system by providing a manufacturing condition master, so design changes can be made at the time of progress update at the completion of each process. The immediate availability of the product is checked, reducing the man-hours required to manually search for the actual product one by one, and making the application of design changes more immediate and accurate.
