Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system for managing production conditions of various industrial products such as fibers, films and chemical products.

[0002]

2. Description of the Related Art Along with the increase in production of small-quantity, high-value-added varieties and production of high-value-added varieties, production processes (hereinafter referred to as "processes") have been renewed and abolished very frequently. In such a case, in the production condition management system that manages such production conditions, the corresponding product condition table,
It was necessary to modify the equipment condition table or the input / output program of the switching instruction distributed to the related departments every time the process was revised or abolished. This is because, for example, when a new process is introduced with the start of production of a new variety, a new production condition management data item (hereinafter referred to as "management data item") that is required for the first time is added. This is because, in many cases, the production condition management system needs to change the screen design of the input / update screen regarding the new management data item and the format of the print form. On the contrary,
Some management data items are no longer needed due to the introduction of new processes.

As a print form of the production condition management system, for example, a process switching instruction is most frequently printed. The switching instruction is a list of management data items that should be switched among the production conditions of the process when a specific product is produced in a certain production facility and then the production product is switched to another product. It is always issued. With today's small quantity and variety,
Product types are frequently switched, and switching instructions are issued frequently accordingly.

In general, there are usually a plurality of departments (eg, N departments) related to one process from upstream to downstream of the process, and a large number of kinds (eg, n kinds) of patterns are required for each department. Because there is 1
A large number (eg N ×
Switching instructions of the type n) are required.

Therefore, when the production condition management data items are increased or decreased by the introduction of a new process, all of the programs for outputting the switching instruction issued when the process is switched to another process are modified. I needed to add. In other words, the data storage position inside the file that stores the item names, attributes, number of digits, output data such as the check method of input data, and production conditions of the increased or decreased management data items in each instruction are switched for each instruction. Had to change to. Further, it is necessary to similarly change the program relating to the screen of the terminal device for inputting the increased or decreased management data item.

Moreover, if the number of products to be produced increases by one, the number of processes does not increase by one process, but the number of different processes increases depending on the type of production equipment used to produce the product. In general, there are many places to modify the output of various forms such as books or programs related to screen display, so a lot of man-hours are required for investigation, modification and testing, and it takes a long time to obtain satisfactory results. I needed it. Therefore, the burden on the system department that manages the program was very heavy.

Also, the addition of one set of production equipment similarly generated a large number of new processes, which necessitated the same program modification as described above.

[0008]

SUMMARY OF THE INVENTION It is, therefore, a first object of the present invention to provide a production condition management system which does not require modification of output related programs due to process modification.

A second object of the present invention is to provide a production condition management system in which the setting change due to the increase or decrease of management data items accompanying the start of production of a new product type or the introduction of new production equipment is reduced. is there.

[0010]

A production condition management system of the present invention for solving the above problems comprises a terminal device and a storage device, and the storage device includes a production condition management data file and the terminal. An output definition master file for storing the output condition of the production condition management data item output in the device and the data storage position in the production condition management data file, and the terminal device stores the output definition master file and the output definition master file. It is characterized in that it accepts input or update of the contents with the production condition management data file.

Another aspect of the production condition management system of the present invention includes a terminal device, a storage device, and a printing device, wherein the storage device includes the production condition management data file and the printing device or the terminal. An output definition master file for storing the output condition of the production condition management data item output in the device and the data storage position in the production condition management data file, and the terminal device stores the output definition master file and the output definition master file. It is characterized in that it accepts input or update of the contents with the production condition management data file.

A preferred aspect of the production condition management system of the present invention is characterized in that the output condition includes an item name, an attribute and a digit number of the production condition management data item.

Further, in a preferred aspect of the production condition management system of the present invention, the production condition management data item includes a product condition for each product type and an equipment condition for each production facility. Is characterized in that it is independently input or updated in the terminal device.

[0014]

The production condition management system of the present invention will be described below.

In the production condition management system of the present invention, the output condition of the management data item output from the terminal device or the printing device using the production condition management system and the data storage position in the production condition management data file of each management data item are set. The output definition master file is stored in the output definition master file, and the output definition master file is stored in a storage device accessible from the terminal device, like the production condition management data file. Moreover, the terminal device is configured to be used when inputting or updating the contents of the production condition management data file together with the output definition master file.

Therefore, when it is necessary to correct the format of the output form such as a switching instruction or the screen display format on the input or update screen due to the increase or decrease of the management data items due to the introduction of a new process, etc. The user operator who manages can input or update the contents of the output definition file by himself without using a high-performance and expensive development terminal. Therefore, it is not necessary to modify the program in the system department every time the number of management data items increases or decreases, and the labor and time for that can be significantly reduced. In addition, it is possible to modify the above-mentioned format or the like with an inexpensive user-side terminal having no special function.

In a preferred aspect of the production condition management system of the present invention, the production condition management data item includes a product type condition determined for each product type and an equipment condition determined for each production facility. Can be input or updated independently of each other. Therefore, when one kind of product is added, basically only the management data item relating to the kind condition can be input or updated. With such a data structure, the limited capacity of the storage device can be saved or the system throughput can be improved.

In general, a process is newly introduced by the number of production equipments capable of producing one kind of product, but as described above, the condition of the product and the condition of the equipment are classified and input or updated independently. As a result, it is possible to collectively input or update management data items for the same product type or the same equipment. That is, for example, even when the number of processes increases due to an increase or decrease in the number of management data items and the number of processes increases, the management data items included in the product type conditions are increased or decreased once, and the management data items of all processes are changed. It is possible to increase or decrease at once.
This is the same even when the production equipment is increased by one type. That is, it becomes possible to manage the definition of the output condition, which was originally required for each individual combination of the production equipment and the product type, in a matrix by classifying the equipment condition and the product type condition.

If there is a management data item that needs to be output or is unnecessary only in the case of a specific combination of production equipment and product type, it is preferable to define only such a management data item for each combination. In this case, product condition and equipment conditions are stored separately in the output definition master file or production condition management data file and managed in matrix as described above, and for each combination of specific product and equipment. It is preferable to store the output conditions defined in 1. in a separate file (individual output definition master file or individual production condition management data file) or part of the above output definition master file or production condition management data file. . In any case, most of the management data items need to be managed in matrix as described above.
The trouble of modifying the output conditions is greatly reduced.

As the internal structure of the file as described above, data is managed for each individual combination of product type and equipment, but when inputting or updating the contents, the product type condition and the equipment condition are treated independently. You may take the method. In this case, for example, when a management data item is added for a certain product type, the management data item should be added collectively to each data field of the combination of all the equipment that produces the product type and the product type. You can do this.

In addition, management data items are input or updated for each combination of product type and equipment.
When you enter or update the management data items (not depending on the equipment) specific to the product type in combination with the specific product type, the management items are collectively displayed in the data field of the combination of the product type and other equipment. May be input or updated. In this case as well, the data structure inside the file may take any of the above-mentioned formats.

Further, by dividing the product type condition from the equipment condition, for example, when a new management data item is examined by a department on the user side when a new process is introduced, a management unrelated to the department is managed. There is no need to consider data items (mainly equipment conditions). Therefore, it becomes extremely easy for the user to input or update (maintain) the output condition of the management data item. When the output conditions are not managed in a matrix, it is necessary to consider all the management data items, so individual user departments cannot handle them, and the same user side opinions from many departments from upstream to downstream. However, the maintenance on the user side may be complicated, but the matrix-like management as described above facilitates the maintenance and eliminates the burden on the work on the user side.

Next, one embodiment of the production condition management system of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a configuration example of hardware used in an embodiment of the production condition management system of the present invention.

And the printer 105 are connected to each other. Auxiliary storage device 1
In 04, for example, a screen definition master file, a table making definition master file, etc. are stored as output definition master files, and a product condition management master file, equipment condition master files, etc. are stored as production condition management data files. Note that these files do not have to be physically stored in the same storage device as long as they can be read or written from the terminal device 100. Therefore, it may be stored in a separate storage device or may be commonly connected to many terminal devices.

The printing device 105 may be a device which permanently prints on a medium such as paper, or a device which prints temporarily,
It may be displayed or notified, and output to a medium or the like that can be erased when unnecessary. Further, the printing device 105 may be commonly connected to many terminal devices.

FIG. 2 is a block diagram showing the functions of the production condition management system of this embodiment. The present embodiment is a system for managing production conditions and automating the output of a switching instruction or the like particularly when switching product types. The main function is to input or update the production conditions (production control data items) when a production manager (user) or the like produces each kind of equipment in the facility, and manage it.
In addition, there is a case where a switching instruction is issued to notify relevant departments of a change in production conditions when a product type switching occurs. Subroutines for realizing this function are the product type condition master (file) input / update screen S3000, the equipment condition master (file) input / update screen S4000, and the switching instruction issuance screen S5000. This example of the embodiment is configured so that the production conditions can be divided into production conditions for each product type and production conditions for each facility and can be input or updated independently. Although various methods can be considered for the configuration of these files and the configuration of the input screen,
In this embodiment, the product type condition and the equipment condition are stored in separate files, and the operator's input and update are also performed on separate screens. This format is simple and easy to maintain.

When it becomes necessary to change the specifications of the above-mentioned functions, that is, to revise or abolish management data items due to the addition of new varieties, the screen design (screen definition) of the input screen of the production conditions and the format of the switching instruction format The change can be made by the user himself. That is, the screen definition information in each of the input / update screens described above is saved in the screen definition master file in the auxiliary storage device 104, and the format information of the form such as the switching instruction printed in each screen is also stored in the table making definition master file. It is configured so that it can be saved and can be freely changed by the user when the above specification changes are required. If necessary, the system department etc. allows specification changes by the user side,
You may be allowed or prohibited.

The procedure of each screen will be described below.

FIG. 3 is a flow chart showing the procedure of the screen definition master input / update screen. Before using the system of the present embodiment, it is necessary to first define the screen of each input / update screen on this screen. Further, the specification of the screen definition after that is also changed on this screen.

First, the screen type is input (S100).
1). The screen type refers to a product type condition master input / update screen or a facility condition master input / update screen, and the screen to be input or updated is selected in this step. Next, input the target product type or equipment (S1
002). If the product type condition master input / update screen is selected in S1001, the target product type is input here. If the equipment condition master input / update screen is selected, the target equipment is input. Next, the screen definition master file is searched, and the screen definition contents of the input / update screen of the target product type or equipment condition are displayed (S1003). The contents of the screen definition include, for example, item names of management data items, attributes such as numerical values or characters, number of digits, display position on the screen and check method of input data value, display position on the screen,
There is the size of the character. Among these, it is preferable that the operator inputs the item name, the attribute, the number of digits, the method of checking the data value, etc. depending on the contents of the management data item. On the other hand, for example, it is preferable that the display position on the screen and the size of characters are automatically assigned by the system. At the same time, the operator also specifies the storage location in the product condition master file and the equipment condition master file of the management data item, but since it is troublesome for the user to handle such internal system settings, this is also the system side. It is preferable to assign it automatically.

Subsequently, the management data item to which the specification of the screen output information is added, changed or deleted is selected, and a new definition is input or updated (S1004). Next, the input or updated content is confirmed (S1005), and if further input / update is performed if there is a problem (S1006), S10.
Returning to 04, if the input / update is completed, the screen definition master file is updated (S1007).

FIG. 4 is a flow chart showing the procedure of the table making definition master input / update screen. Before using the system of this embodiment, it is necessary to first define the format of a form to be printed (table definition) on each input / update screen, switching instruction issue screen, and the like.
In addition, the specifications of the table-making definition after that are also changed on this screen.

First, the screen type is input (S200
1). This screen type refers to a product type condition master input / update screen, a facility condition master input / update screen, or a switching instruction issue screen. In this step, the screen for issuing the form to be input / updated is selected. Next, the form type is input (S2002). Here, the form type is
Refers to the condition table of the target product or equipment or the type of switching instruction. When the product condition master input / update screen is selected in S2001, the target product is selected here. When the equipment condition master input / update screen is selected, the target device is selected and the switching instruction issuance screen is selected. Input the combination of the target product type and equipment, or the combination before switching and the combination after switching. Next, it is inputted which pattern of the form of the form selected in S2002 is to be input / updated (S2003). This is because it is necessary to prepare a large number of patterns even for the same type of form (combination of product type and equipment, etc.) because the required items differ depending on the relevant department of the issue destination. Next, the table-making definition master file is searched, and the table-making definition contents of the target form pattern are displayed (S2004). The contents of the table-making definition include, for example, item names of management data items, attributes such as numerical values and characters, number of digits, print position on a form, and size of characters. Of these, it is preferable that the operator input the item name, attributes, number of digits, etc. according to the contents of the management data item, but for example, the printing position on the form and the size of the character etc. should be automatically assigned by the system side. Is preferred.

Subsequently, the management data item to which the specifications of the form output information are added, changed or deleted is selected, and a new definition is input or updated (S2005). Next, the entered or updated contents are confirmed (S2006), and if there is a problem and further input / update is performed (S2007), S20.
Returning to 05, when the input / update is completed, the table-making definition master file is updated (S2008).

FIG. 5 is a flow chart showing the procedure of the type condition master input / update screen. On this screen, enter the production conditions for each product type. At this time, screen output and form output are performed according to the screen definition and the table-making definition defined in the above two definition input / update screens. Also, when introducing a new variety, a new variety condition is entered. At this time, if a new management data item is needed, that item is added in advance on the screen definition master input / update screen S1000.

First, the target product type is input (S300
1). Next, the product type condition master file is searched, and each management data item of the input product type condition of the target product type is displayed according to the screen definition master file. (S300
2). Next, enter / update management data items (S
3003). At this time also, input / update is performed based on the information in the screen definition master file. This is because the screen definition includes a method of checking the value of data to be input and the like. Next, the entered or updated contents are confirmed (S3004), and if there is a problem and further input / update is performed (S3005), the process returns to S3003, and if the input / update is completed, the product type condition master file is updated. (S3006).

Subsequently, if necessary, the type condition table of the inputted or updated target type is printed according to the table making definition master (S3007). The product type condition table is a printout of the production conditions related to the target product type in a form such as a list, and there are various formats depending on the department of the issuing destination, and the necessary amount is printed here. Such kind of condition table may be printed before and after S3003, or a subroutine may be prepared separately.

Although the target product type is input in S3001 described above, it is also possible to input the equipment to be produced at the same time as the target product type and to input the process of combining the equipment and the target product type. In this case, the product type condition master file has a storage field for each combination, and management data items common to the production of the target product type (not dependent on the equipment) can be collectively input / updated. Other file configurations and screen management methods as described above may be used.

FIG. 6 is a flow chart showing the procedure of the equipment condition master input / update screen. On this screen, enter the production conditions for each production facility. In doing this, the above 2
Screen output and form output are performed according to the screen definition and the table definition defined in the one definition input / update screen.
In addition, new equipment conditions are input when introducing new equipment.
If a new management data item is needed at this time, add that item in advance on the screen definition master input / update screen.

The procedure on this screen is almost the same as the product condition master input / update screen.

First, the target equipment is input (S400
1). Next, the equipment condition master file is searched and each management data item of the equipment condition of the input target equipment is displayed according to the screen definition master file. (S400
2). Next, enter / update management data items (S
4003). At this time also, input / update is performed based on the information in the screen definition master file. This is because the screen definition includes a method of checking the value of data to be input and the like. Next, the entered or updated contents are confirmed (S4004). If there is a problem and further input / update is performed (S4005), the process returns to S4004, and if the input / update is completed, the equipment condition master file is updated. (S4006).

Subsequently, if necessary, the equipment condition table of the inputted or updated target equipment is printed according to the table making definition master (S4007). The equipment condition table is a printout of the production conditions related to the target equipment in a format such as a list, and there are various formats depending on the department to which the equipment is issued. Such printing of the equipment condition table may be performed before or after the above S4003, or a subroutine may be prepared separately.

FIG. 7 is a flowchart showing the procedure of the switching instruction issue screen. On this screen, a switching instruction for issuing the changed production conditions to the relevant departments is issued when the production type is actually switched at a specific production facility. At this time, the equipment conditions of the equipment input on the above-mentioned input / update screen and the product type conditions of the product before or after the switching are stored in the table definition master input / update screen for each switching instruction. Print out according to the format.

First, product type switching information data is input (S5001). As the product type switching information data, equipment,
Various data such as the factory with the equipment, the type before switching, the type after switching, and the scheduled switching date can be considered. Next, the equipment condition master file and the product type master file are searched, and the equipment condition of the input equipment and the data of the product type of the product before and after switching are extracted (S500).
2). If the type before switching does not matter, it is not necessary to extract the data of the type condition. Next, data of each switching instruction is created based on each extracted data (S5).
003). In this case, when the amount of data is large, for example, a temporary file is created in the auxiliary storage device.

Finally, each switching instruction is printed according to the table-making definition master file (S5004).

Although the screen definition of the switching instruction issuance screen is not stored in the screen definition master file in this embodiment, it is possible to design this screen on the user side by using such a method. Good.

EXAMPLES The production condition management system shown in FIGS. 1 to 7 was constructed and applied to the management of the production conditions in the nylon long fiber production process in a factory having 20 production facilities.

A commercially available personal computer is used as the terminal device 100, and the auxiliary storage device 104 and the printing device 1 are used.
As 05, a commercially available personal computer was used. The terminal device 100 and the auxiliary storage device 104 are connected to each other via a network so that the user can input / update the screen definition and the table definition with the permission of the system department. One printing device 105 is provided for each terminal device 100.
I connected them one by one.

There are 150 types of nylon filaments produced in this factory, and there are 20 to 40 management data items for each type, and there are an average of 10 related departments that receive switching instructions when switching types. Therefore, there are over 1000 types of switching instructions alone.

A new process is introduced, for example, about once every two months when the production of a new variety is started, and the case where the specification of the management data item is changed is included about once or twice a year.

The table definition of the switching instruction and the screen definition of the type condition input / update screen are changed in accordance with this, in the production management related departments. As a result, it became unnecessary to modify the program or test the modified program, and it became possible to smoothly change the specifications such as the switching instruction when introducing the new process.

Further, since the product type condition and the equipment condition can be managed in a matrix manner, various kinds of maintenance work associated with the start of production of a new product type have become extremely easy.

[0055]

According to the production condition management system of the present invention, since the input or update of the production condition management data file and the screen or the output definition master file of the printing device can be accepted from the terminal device, the user side inputs.・
It is possible to freely change the screen definition of the update screen or the specification of the form format.

Further, the specification change of such a format can be performed by a normal user side terminal having no special function.

Further, according to the production condition management system of the present invention, the production condition management data item includes the product type condition and the equipment condition for each product type, and can be independently input or updated in the terminal device. It is not necessary to re-input output definitions such as input / update screens for each individual combination with each production facility when introducing new processes accompanying the start of production of new products. Changes can be implemented smoothly and efficiently. Moreover, since such a data structure is used, it is possible to save the limited storage capacity and improve the system throughput.
