DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated manufacturing design processing system which is manufactured through a plurality of manufacturing processes and is used, for example, in a steel product manufacturing line.

[0002]

2. Description of the Related Art Steel manufacturers manufacture a large variety of products such as cold-rolled steel sheets, surface-treated steel sheets, electromagnetic steel sheets, stainless steel sheets, rails, seamless steel pipes, spiral steel pipes, steel sheet piles, and the like. These products, depending on their type,
It is manufactured through a number of manufacturing processes such as a converter process, a casting process, a rough rolling process, a hot rolling process, a cold rolling process, and an annealing process.

FIG. 13 is a diagram for explaining a conventional integrated manufacturing design processing system. Generally, when an order is received from a customer, a steel product is first designed in the head office by assigning necessary characteristics such as a material of the product and a tensile test according to the order. Data as a result of the product design performed at the head office is sent to the steelworks and input to the computer (step S91). At the steelworks, for each order, based on the data (product specifications) required to manufacture the product, such as the required characteristic values, order dimensions, required quantity, and delivery date, the manufacturing process that passes and the operation of the manufacturing process A manufacturing design for determining the conditions is performed (step S92). This manufacturing design uses a group of tables and a group of logics to consistently design from the converter process to the final packing process, and is called an integrated manufacturing design. The result (manufacturing specification) of the integrated manufacturing design is output to each manufacturing process necessary for manufacturing a product (step S93).
The actual production is performed by operating each production process based on the production specifications.

[0004]

As described above, the integrated manufacturing design is performed consistently for all steps from the beginning to the end. This design method can be easily performed when the number of manufacturing steps is small. However, when the number of manufacturing processes increases, various manufacturing methods can be performed, and the number of manufacturing design items becomes enormous, so that a processing program becomes complicated and difficult. For example, if you only order slabs,
The design is simple because only the design of the slab, that is, the design of the converter step and the casting step is required. However, when manufacturing a steel sheet, it is necessary to further perform manufacturing design in a hot rolling step, a cold rolling step, an annealing step, and the like. The integrated manufacturing design at a steel mill is usually batch-processed because the number of manufacturing design items increases.

Meanwhile, the conventional integrated manufacturing design processing system creates information necessary for each manufacturing process using a table group and a logic group. Since the contents of the table group and the logic group are frequently changed, the integrated manufacturing design is disposable, and the integrated manufacturing design is performed for each order every time. Therefore, even if an order is issued from the same customer with the same specifications, for example, an order for a steel plate used in the same passenger car, the same integrated manufacturing design is repeatedly performed each time the order is placed. As described above, the conventional integrated manufacturing design is performed every time an order is placed, and even if the order is the same, the same work must be performed again, and the data of the integrated manufacturing design performed in the past cannot be effectively used. There is a problem.

[0006] Further, once a table row (hereinafter also referred to as a record) used in the integrated manufacturing design is created, it is semi-permanently present in the table even if it is no longer needed. It is impossible for anyone other than the creator of the record to determine the necessity of the record because it is unknown only to the creator of the record. is there. On the other hand, it is not easy even for the creator of the record to determine whether or not the created record is really necessary. Thus, in the conventional system,
Once created records could not be organized. Therefore, if you have been using the system for many months,
There is a problem that the number of unnecessary records increases, and it takes time to perform a matching process when performing an integrated manufacturing design using a table group.

The present invention has been made on the basis of the above-mentioned circumstances, and it is possible to effectively utilize data of past integrated manufacturing design and to easily manage records of each table. The purpose is to provide a system.

[0008]

An integrated manufacturing design processing system according to the present invention for achieving the above object has an integrated manufacturing design processing system for managing and operating a plurality of manufacturing processes based on product specifications. A manufacturing design processing system,
Manufacturing design creating means for performing the integrated manufacturing design using a table group and a logic group based on the product specifications, and a manufacturing specification which is a result of the integrated manufacturing design created by the manufacturing design creating means. Storage means for storing in association with the product specifications, it is determined whether or not a product specification that matches the input product specification is stored in the storage means, and if it is stored, the integrated product design of the matched product specification is determined. When the manufacturing specification which is the result is read out, if it is not stored, the manufacturing design creating means performs the integrated manufacturing design, and the processing means for outputting the result, and when the manufacturing design creating means uses the table group, Table management means for managing the number of times for each row of the used table and managing the history for each row of the table group;
It is characterized by having.

According to the present invention, since the integrated manufacturing design is performed based on the product specification and the result is stored in association with the product specification, the result can be easily and quickly read out for the integrated manufacturing design once performed. Can be output. Further, since the table management means manages the number of times of use for each record of each table and manages the history for each record, it becomes easy to determine the necessity of each record.

[0010]

At each steelworks, in order to produce a product that conforms to the product specifications created at the head office, which manufacturing process is used from the various manufacturing processes of the above steel material manufacturing line, how to use it, Design process specifications and production schedule adjustment. For example, hot rolling process D
When using the cold rolling step E and the cold rolling step D, it is necessary to design how many mm the thickness is to be extended in the hot rolling step D, and in the cold rolling step E how many mm the thickness is to be extended. A manufacturing design for generating necessary data in each manufacturing process is performed. This manufacturing design is an integrated manufacturing design that consistently designs all of the manufacturing processes from the beginning to the end.

As shown in FIG. 2, the integrated manufacturing design processing system according to the present embodiment includes an input unit 10 such as a keyboard for inputting product specifications and manufacturing specifications, and integrated manufacturing based on the input product specifications and manufacturing specifications. Control unit 1 that controls design

45, a table group and a logic group stored in the second storage unit 14 based on an instruction from the control unit 11, and a manufacturing design creation for performing an integrated manufacturing design with reference to the manufacturing method setting table. Unit 15, a table management unit 16 for managing a table group or a logic group, and based on product specifications and manufacturing method specifications stored in the first storage unit 13 when the contents of the table group or the logic group are changed. A regenerating unit 17 for re-executing the integrated manufacturing design and storing the result in the first storage unit, and a manufacturing specification management unit for managing the manufacturing specification which is the result of the integrated manufacturing design stored in the first storage unit 13 18. The control unit 11 includes a code display unit 111, an item display unit 112, and a data assignment source display unit 113.

The input unit 10 inputs the product specifications to a server computer using a keyboard or the like based on the product specifications sent from the head office or sets manufacturing specifications. The product specifications may be directly transmitted from the computer at the head office to the server computer at the steelworks using a communication line or the like. The output unit 12 outputs the manufacturing specifications, which are the result of the integrated manufacturing design, on a paper or the like using a printer or the like, displays them on a screen, and transmits the manufacturing processes using a communication line or the like.

The first storage unit 13 stores the result of the integrated manufacturing design that has already been created in association with the product specification and the manufacturing method specification. For example, with the main items of the product specifications (standards, consumers, applications, dimensions, quality, etc.) and the materials and manufacturing processes of the manufacturing specifications as key items, the corresponding manufacturing specifications as a result of the integrated manufacturing design are stored. In addition, the result of the integrated manufacturing design
The control unit 11 may control the integrated manufacturing design based on the product specifications, storing the information in association with only the product specifications.

The group of tables stored in the second storage unit 14 is prepared for each manufacturing process. In the integrated manufacturing design processing system of FIG. 1, about 200 tables are prepared. Here, the table refers to a table. For example, a table for materials used when determining operating conditions of most manufacturing processes, a table of hot rolling accuracy used in a hot rolling process, a table of cold rolling accuracy used in a cold rolling process, a skin pass process There is a table of the skin pass reduction rate used in the above. As shown in FIG. 8, key items, grant items, and record management items are provided as items of each table. In the case of a material table, for example, key items include items such as a product standard, a user name, a product dimension use, and quality, which are main items of product specifications. The items to be provided include items such as hardness, surface roughness, tensile test, bending test, crystal grain size, and workability test which are provided by the steelworks. The record management items include items such as the history of each record and the number of times used for the integrated manufacturing design. The record history includes, for example, the name of the setter who created and set the record, comments such as the reason for creating the record, the set date when the record was set, and the revision date when the record was revised And the date of use used in the integrated manufacturing design.

Logic is a computer language (eg, COBO) such as if or while for determining processing conditions.
L). Also, the second storage unit 14
The manufacturing method setting table 645 stores the possible manufacturing methods in the form of a table for each order. In the manufacturing method setting table 645, a material and a manufacturing process are provided as key items of the manufacturing method specification. If the material is different, the material of the raw material to be put into the converter process is different, so that the result of the integrated manufacturing design is different. Moreover, for one order, for example, it may be manufactured from a material called Z1,
In some cases, it may be manufactured with the material No. 2. In this case, it is considered that there is one manufacturing method for each material. In addition, a large steelworks usually has a plurality of manufacturing steps for performing the same processing, for example, a plurality of annealing steps. In this case, no matter which annealing process is used, a product can be produced as ordered, but the result of the integrated manufacturing design differs depending on which annealing process is used. Also in this case, it is considered that there is one manufacturing method for each of a plurality of manufacturing steps that perform the same processing. Which manufacturing method to use,
That is, which manufacturing process is to be used and which material is to be used among a plurality of manufacturing processes for performing the same process is set in advance. However, as will be described later, which manufacturing method is used is finally determined by adjusting the production schedule of each manufacturing process of the entire steelworks.

FIG. 3 is a diagram showing a part of the production method setting table for the order α. The first line is for the order α
The material is Z1 and is used when performing a representative integrated manufacturing design in which an integrated manufacturing design is performed by using F1 as an annealing step, G1 as a plating step, and other predetermined manufacturing steps. Less than,
The material Z1 used in the representative integrated manufacturing design is referred to as a representative material, and the other materials are referred to as sub-materials. One manufacturing process used in the representative integrated manufacturing design is a representative process, and the processing content is the same as the one manufacturing process. Are referred to as sub-processes.
The order is the same as the representative integrated manufacturing design, but an integrated manufacturing design that differs from at least one of the material and the manufacturing process is referred to as a sub-integrated manufacturing design. When the manufacturing method specification for the order α is not set, the manufacturing design creation unit 15
A representative integrated manufacturing design is performed using the representative material and the representative process in the first row of this table. If a manufacturing method is specified, a sub-integrated manufacturing design is performed using the specified material and manufacturing process. Note that, in FIG. 3, the item of possible materials describes usable materials with priorities. The items of the available line list the processes that can be used in each of the manufacturing processes with priorities. This allows the person in charge to know what other sub-integrated manufacturing designs can be performed when the representative integrated manufacturing design is performed.

The second line is used when sub-integrated manufacturing design 1 is performed on the order α with only the representative integrated manufacturing design and the annealing process being different (annealing process F2). Similarly, the third line is used when performing sub-integrated manufacturing design 2 which is different from the representative integrated manufacturing design only in the annealing step and the plating step. The fourth line is used when performing the sub-integrated manufacturing design 3 which differs only in the material from the representative integrated manufacturing design. Similarly, the manufacturing method setting table is
The order α has data on sub-materials and sub-processes used when performing sub-integrated manufacturing design with different manufacturing methods. The above table is similarly created for other orders. If there are a large number of manufacturing methods for one order, it is possible to search for the sub-integrated manufacturing design by specifying the sub-materials or search the sub-integrated manufacturing design by specifying the sub-process. You may.

When manufacturing a product that has never been manufactured, the manufacturing design creating unit 15 creates a table group or logic stored in the second storage unit 14 based on the product specification and manufacturing method specification of the product. Group 641, and manufacturing method setting table 6
Using 45, an integrated manufacturing design for determining operating conditions and the like of each manufacturing process is performed. The table management unit 16 manages tables and logics. For example, the date on which a record is created, the date on which a record is changed, the date on which the record is used in the integrated manufacturing design, the number of times of use, and the like are automatically managed. When a record is changed, the range of the manufacturing specification affected by the change is automatically displayed. Further, when the table is changed, the table management unit 16 simultaneously displays the old record and the new record as shown in FIG. That is, in this embodiment, when a record is modified, a modification screen is displayed instead of directly modifying each record. When the person in charge issues an instruction to change the record from the keyboard or the like, in the initial state, the same data is put in the old record and the new record and displayed on the screen. The person in charge modifies the numerical values and English characters of the item to be modified as necessary. When displaying the new record for correction and the old record on the screen, the control unit 11 also displays the number of digits that can be input as shown in FIG. In FIG. 12, ":" means that numerals or alphanumeric characters can be input as symbols. “*” Means that a number indicating a number can be input. The numbers “:” and “*” indicate the number of digits that can be input. By the way, when each record is displayed on the screen, if each item name and its data are displayed as they are, the number of digits of the item name and the data increases, so the abbreviated name is used for the item name. For example, one of the key items in FIG.
The item name in the column is “export domestic category”, but the formal item name “export domestic category” is abbreviated to “import country”. In addition, if formal data is displayed for each data, the record becomes long. Therefore, as shown in FIG. 9, the data of each item is displayed by a code using numerals and English characters. Therefore, skill is needed to understand what the short names and codes, for example, "H" and "1" mean. Therefore, in the present embodiment, a file has a display item table that describes the relationship between the formal item name and the abbreviated name, and a code table that describes the relationship between the code and the original data displayed by the code. When the person in charge designates the displayed code to refer to the code table, for example, when designating “1” in the first column of the new record in FIG. 9, the code display unit 111 of the control unit 11 10, the code and the original data displayed by the code are displayed on the screen. In this case, all the codes that can be input are displayed as inputtable candidates in this field, so that the operation of correcting the new record by the person in charge is simplified and assured. Regarding the shortened item names, the item name display unit 1 of the control unit 11
12 displays the formal item name and the abbreviated item name on the screen in the same manner.

The table management section 16 has a function of retrieving items and data in the table. For example, it is possible to search only records that include "Japan Automobile Manufacturing Co., Ltd." as a customer name in a key item. This allows
You can easily see how many records include "Japan Automobile Manufacturing Co., Ltd." Further, as the export domestic classification of the granted item, for example, where a record including “export order” is located can be searched and found.

When the contents of the table group or the logic group are changed, the regenerating section 17 re-performs the integrated manufacturing design based on the product specifications and manufacturing method specifications already stored in the first storage section 13. At this time, all the integrated manufacturing designs may be redone, but in the present embodiment, only the integrated manufacturing designs performed using the records before the change are read out, and the data is regenerated. In addition, the items of the new and old integrated manufacturing designs can be compared and the results can be displayed in a table format. In addition, when redoing the integrated manufacturing design, regenerate quickly by redoing only the manufacturing process related to the changed record without processing other manufacturing processes unrelated to the changed record. Is also good.

FIG. 4 shows the main storage section 631 of the first storage section 13.
FIG. 9 is a diagram for explaining the result of the integrated manufacturing design stored in the storage device. The state illustrated in FIG. 4 indicates that, for the order α, the result of the representative integrated manufacturing design and the result of the sub-integrated manufacturing design 1 have already been created and stored. in this way,
The storage unit 631 stores the results of the representative integrated manufacturing design and the sub-integrated manufacturing design that have already been created in association with the order (product specification) and the manufacturing method specification. In the present embodiment,
Management items are set in the manufacturing specifications resulting from the integrated manufacturing design. The management items include items such as the creation date and time of each manufacturing specification, the reason for creation, the date of revision and abolition, the reason for revision and abolition, the number of hits, the date of use, the expiration date, and the contract. A contract is an order number. Some orders from customers are filled and others are not. Even if orders of the same standard and same size are repeatedly issued by the same customer, if the month changes, the delivery date and quantity will change, so contracts are made for each month. Also, the delivery of the product,
Since the order is performed for each order, an order number is assigned as necessary to distinguish orders that are continuously received from the same customer.

The manufacturing specification management unit 18 manages the number of times of use for each manufacturing specification and also manages the history of each manufacturing specification. For example, the date of creation, the date of abolition, the number of hits, and the date of use of each manufacturing specification are automatically managed.
Further, the manufacturing specification management unit 18 manages the expiration date of each manufacturing specification. For example, there are manufacturing specifications that are only allowed to be used for a few months while the client is testing. In this case, since the manufacturing specification cannot be used after the elapse of the period, the fact is displayed at the time of the integrated manufacturing design.

Data providing source display unit 113 of control unit 11
When the manufacturing specification, which is the result of the integrated manufacturing design, is displayed on the screen in a table format and the data is specified by a mouse or the like, the table number and record number of the table to which the data is assigned are displayed on the screen. indicate. When the manufacturing specification is created, a file is created which describes from which record of which table the data of each item of the manufacturing specification is given. When data is designated by a mouse or the like, the table number and record number of the assigning source are displayed with reference to this file.

Next, the operation of the integrated manufacturing design processing system of this embodiment will be described with reference to FIG. The product specifications created by the head office for the order and the manufacturing specifications determined by the head office or steelworks as necessary are input via a keyboard or a communication line (step S60). Control unit 1
If the product specification does not have a manufacturing specification, the same product specification and manufacturing specification as the order using the representative material and representative process are stored in the main storage unit 631 of the first storage unit 13. A matching process is performed (step S61). This matching process is performed using key items of the product specification and the manufacturing method specification. For example, if the product specification of the order α has a manufacturing method specification for using the material Z1 and the annealing process F2, the order is not a representative integrated manufacturing design,
This matches the sub-integrated manufacturing design 1 shown in FIG. For the products that have been manufactured in the past, for example, the representative integrated manufacturing design and the sub-integrated manufacturing design 1 for the order α, the result of the integrated manufacturing design is as shown in FIG.
31, the result of the manufacturing design is read (step S62). Next, the manufacturing specification is output to paper or a screen via the output unit 12 as necessary (step S63).

By the way, the manufacturing specifications are as follows for each manufacturing process.
Since a large number of items are provided, the number of items becomes enormous, and it is not possible to display all items on one screen.
When viewing the manufacturing specifications with a conventional system, portions that are off the screen and are not displayed on the screen are displayed on the screen by scrolling the screen horizontally.
Therefore, it takes time and is complicated to search for necessary items. On the other hand, in the present embodiment, when the manufacturing specifications are displayed on the screen, as shown in FIG. 11, the display is folded in accordance with the size of the screen, and one long line is displayed in a plurality of rows. Like the general spreadsheet list,
When there are a large number of data items, if there are many items, if the display is folded back and displayed in a plurality of rows, there is a disadvantage that the data portion cannot be seen. However, in the case of the manufacturing specification, the number of items is enormous. However, since there is only one or several pieces of data for one item, the data is not hidden even if it is folded and displayed. Therefore, when one manufacturing specification is displayed on a screen, it is possible to display more items on one screen by folding back and displaying a plurality of stages, and it is possible to easily search for necessary items. When outputting to paper, for the same reason, a plurality of columns are displayed.

In the present embodiment, the matching process of the management item is performed in the matching process of step S61.
For example, it is determined whether the hit manufacturing specification is within the expiration date or whether the contract is the same. As a result, more accurate and efficient matching processing can be performed as compared with the conventional system. Furthermore, in this embodiment, when the manufacturing specifications are displayed on a screen or paper, the management items are also displayed, so that the last use date and the number of times of use can be known. Therefore, it is possible to easily determine whether or not the manufacturing specification is truly usable and manage the manufacturing specification. For example, if the last use was 10 years or more, the manufacturing specification may be deleted. Also,
It is also possible to arrange each manufacturing specification by referring to the number of times of use of each manufacturing specification. This management item matching process may be performed as needed, instead of being performed constantly.

If the manufacturing specification of this order is not stored in the main storage unit 631 in the matching processing in step S61, a new integrated manufacturing design is performed in step S70. If the product specification does not include the manufacturing method specification, the control unit 11 sends a signal to the effect that the integrated manufacturing design is performed using the representative material and the representative process to the manufacturing design processing unit 15. The manufacturing design processing unit 15 performs a new integrated manufacturing design using the table group and the logic group stored in the second storage unit 14 and the manufacturing method setting table to create manufacturing specifications (Step S).
70). For example, the material of the final product is substantially determined by the raw materials to be put into the converter, but also greatly changes in an annealing step, a rolling step, and the like after the converter step. For this reason, for each of these manufacturing processes that affect the material, the target values and the upper and lower limits of the components such as carbon, phosphorus, and manganese of the steel material and the working conditions are determined. The production design of the thickness of the surface-treated steel sheet is performed as follows. For example, when the sheet thickness is 0.82 mm in the product specification, usually, in the casting step B, a slab P1 of about 250 mm is produced, and the slab P1 is subjected to the hot-rolled steel sheet having a thickness of 3 mm in the hot-rolling step C. P3, the hot-rolled steel sheet P3 was rolled into a cold-rolled steel sheet P4 of 0.8 mm in a cold rolling step E, further annealed in an annealing step F1, and then subjected to a plating treatment of 0.01 mm in a plating step G1 to obtain a skin pass. Surface thickness is adjusted in process H by 0.8
A 2 mm surface-treated steel sheet P5 is produced. For this reason, data for operating each of these manufacturing processes that affect the plate thickness is generated using a table group and a logic group.

When the integrated manufacturing design is performed, the management items, for example, the date of use and the number of times of use are automatically updated by the table management unit 16 for each record of each table. Thereby, for each record, these data can be used as reference data when determining the necessity of the record, and the management of the table is facilitated.

For example, if the order α has a manufacturing specification for performing an integrated manufacturing design using the material Z1, the annealing step F2, and the plating step G2, the sub-integrated manufacturing design 2 shown in FIG. 3 is performed. . The created result of the new integrated manufacturing design is stored in the temporary storage unit 630 of the first storage unit 13 in association with the product specification and the manufacturing method specification (step S71). In step S72, the manufacturing specification that is the result of the newly created integrated manufacturing design is output on paper or the like, and it is checked whether or not the integrated manufacturing design is normal (step S73). If an abnormality is found as a result of the inspection, the process returns to step S70,
After correcting the abnormal part, redo the integrated manufacturing design.
The reason why the wrong integrated manufacturing design is output is that an error occurs when the specification values of the product specification and the manufacturing specification are input from the keyboard. This input error cannot be understood when inputting. For this reason, after performing the integrated manufacturing design, this input error is inspected by looking at the screen or the printed manufacturing specification. Also, as a result of the inspection, when it is found that the data (assigned value) of a given assigned item is wrong, the assigned value is corrected. By the way, when correcting the wrong assigned value of the manufacturing specification which is the result of the integrated manufacturing design,
In a conventional system, it is impossible for an expert to know which table and which record the given value is given by. On the other hand, in the present embodiment, when a given value is designated by a mouse and clicked while viewing the manufacturing specification as a result of the integrated manufacturing design on the screen, the data providing source display unit 113 of the control unit 11 FIG.
As shown in the table, the number of the table in which row the value is given is displayed. Such a display is realized by storing a log when the process of the integrated manufacturing design is performed and adding a function of searching the log. As a result, the work of correcting the data becomes extremely easy, and no skill is required. Also, when displaying the manufacturing specifications that are the result of the integrated manufacturing design on the screen, since one line is long, the data is coded and displayed, and if necessary,
The original coded data can be displayed.
For the same reason, each item name of the manufacturing specification is also abbreviated.

Although an abnormality was found as a result of the inspection,
In some cases, it is not possible to perform an integrated manufacturing design using a table group and a logic group, and it is necessary to manually correct manufacturing specification data for the time being. Since this manufacturing specification cannot be created by integrated manufacturing design using tables and logics, an identification symbol indicating that it is a manually created manufacturing specification was used to clarify this fact. To make it clear that this manufacturing specification is a special exception process.

On the other hand, if there is no abnormality as a result of the inspection in step S73, the result of the integrated manufacturing design is stored in the main storage unit 631 in step S74. For example, when the sub-integrated manufacturing design 2 for the order α shown in FIG. 3 is performed, the result is copied from the temporary storage unit 630 and stored in the main storage unit 631 together with the manufacturing specification and the manufacturing method specification. The result is simultaneously output on paper as a manufacturing specification (step S6).
3). When outputting the result of the above-described integrated manufacturing design, information on other processable sub-integrated manufacturing designs is also output. For example, for the order α shown in FIG. 3, when the representative integrated manufacturing design is performed using the representative material and the representative process,
In addition to the result of the representative integrated manufacturing design, sub-integrated manufacturing design 1 using material Z1 and sub-process F2, material Z1 and sub-process F2
Also, information indicating that sub-integrated manufacturing design 2 using sub-process G2 and sub-integrated manufacturing design 3 using sub-material Z2, sub-process F1, and sub-process G1 can be performed is output.

By the way, usually, for example, orders α, β.
The integrated manufacturing design is processed by a computer at night. The next morning, the person in charge adjusts the production schedule of the entire steelworks based on the results of the integrated manufacturing design for each order α, β ... processed the night before. That is, it is examined whether a product can be efficiently manufactured using each manufacturing process without any problem. This is because when performing the integrated manufacturing design of one order, the result of the integrated manufacturing design of another order cannot be considered. As a result of the production schedule adjustment, for example, when it is found that the operation schedule of the annealing process F1 exceeds a predetermined allowable range, a part of the orders using the annealing process F1 is replaced with the annealing process F1.
Work to change to the one that uses 2.

Referring to FIG. 6, a description will be given of a process for changing the manufacturing method based on the production schedule adjustment with respect to the result of the integrated manufacturing design that has already been created.
Here, a case will be described in which the representative integrated manufacturing design for the order α already performed is changed to the one using the annealing step F2 for the above-described reason. That is, in order to eliminate the overload state of the annealing step F1 found by examining the production schedule, the integrated manufacturing design for the order α is changed to the one using the annealing step F2. Regarding the integrated manufacturing design for the order α, when the representative integrated manufacturing design is performed, it is possible to perform the sub-integrated manufacturing design 1, the sub-integrated manufacturing design 2, and the sub-integrated manufacturing design 3 as described above. Is attached, the person in charge knows that such a change is possible. First, a product specification of an order to be changed and an instruction to use the annealing step F2 are input in step S600. In step S610, a matching process is performed to determine whether or not the result of the integrated manufacturing design corresponding to the product specification and the manufacturing method specification is stored in the main storage unit 631. In this case, since the integrated manufacturing design has already been performed once for the order α, the result of the integrated manufacturing design matching this product specification is read out, and the process proceeds to step S620. If there is no match in the matching processing in step S610, it is an abnormal situation where there is no master, so an error message is displayed and this processing is stopped (step S611).

Next, in step S620, an annealing step F
A matching process is performed to determine whether or not the result of the integrated manufacturing design using No. 2 is in the main storage unit 631 of the first storage unit 13. The matching process in this case is performed using the manufacturing specification key. In the case of the order α, since the result of the sub-integrated manufacturing design 1 is already in the first storage unit 13, the result is read (step S630). The read result of the sub-integrated manufacturing design 1 is output to paper via the output unit 12 as necessary (step S63), and the terminal for controlling the respective manufacturing processes based on the manufacturing specifications via the output unit 12 is provided. It is sent to the computer (step S64).

In the manufacturing method matching process in step S620, if the result of the sub-integrated manufacturing design using the annealing step F2 is not stored in the main storage unit 631 for the order α, steps S70 to S74 in FIG. In the same manner as in the above process, the processes after step S70 in FIG. 6 are performed to newly perform the sub-integrated manufacturing design 2 for the order. After the production schedule is adjusted in this way, the production specifications are actually sent to each production process. In each of the manufacturing processes from the converter process A to the packing process I, based on the manufacturing specifications sent by the terminal computer provided for each,
The conditions necessary for operation are set, and each device is operated to perform processing. As described above, in the present embodiment, the results of the integrated manufacturing design created in the past are stored, so that products having the same quality can be quickly manufactured without fail for products that have been created in the past.

Further, since the present embodiment has the manufacturing method setting table, when the material and the manufacturing process are changed, the manufacturing method can be easily and quickly changed using the manufacturing method setting table. Furthermore, conventionally, for one order,
Only representative integrated manufacturing design is performed using representative materials and representative processes. As a result of adjusting the production schedule, when the representative integrated manufacturing design is changed, the integrated manufacturing design is redone using a new corresponding sub-material or sub-process. On the other hand, according to the present embodiment, not only the representative integrated manufacturing design but also the sub-integrated manufacturing design is stored in the main storage unit. Manufacturing design can be performed quickly.

For one order, it is also possible to perform and store all sub-integrated manufacturing designs using all materials and manufacturing processes. However, it is impractical and inefficient to perform and store in advance all the sub-integrated manufacturing designs for each order in a steel mill where a manufacturing method of about 100 pieces can be considered for one order. Therefore, it is desirable to store only the results of the sub-integrated manufacturing design created according to the actual order. Also, by distinguishing and storing the manufacturing specifications used after the adjustment of the production schedule and the manufacturing specifications used in the initial integrated manufacturing design, when the manufacturing specifications increase, any manufacturing specifications can be deleted. It is easy to determine whether to do so. Further, for the manufacturing specifications actually used, by storing data such as the number of times of matching and the date of use for each manufacturing specification, it is possible to easily determine the validity of each manufacturing specification. .

According to the above embodiment, the number of times of use is managed for each record of each table, and the history is managed for each record. Therefore, the necessity of each record is determined. Will be easier. Further, since the number of times of use and the history thereof are also managed for the manufacturing specification as a result of the integrated manufacturing design, it becomes easy to judge the necessity of each manufacturing specification.

In addition, in the conventional system, when correcting the manufacturing specification as a result of the integrated manufacturing design, it is necessary for a non-expert to know which table and which record should be corrected. On the other hand, according to the present embodiment, it is possible to display the table number and record number of the source table only by designating the value to be corrected. If not, it can be done easily and quickly.

Next, a process for changing a table group or a logic group will be described. When a certain record of a table group is changed by the table management unit 16, for example, the regenerating unit 17 searches for the product specification of the integrated manufacturing design created using the old data of the changed record. If there is a corresponding product specification, read out the product specification and manufacturing method specification and change the table group and logic group,
A new integrated manufacturing design is performed using the manufacturing method setting table, and the data is regenerated. Whether the regenerated data is correct or not is checked before actual production, and a tick is made to determine whether the change has been made correctly. If the inspection passes, the information is stored in the first storage unit 13. The table management unit 1
6, when the table group and the logic group are changed,
A history of who made the change is managed, and this history is used for checking for erroneous input and the like, and is also used for grasping the history of the integrated manufacturing design.

Next, a second embodiment of the present invention will be described. In the first embodiment, an integrated manufacturing design is performed at once for all manufacturing processes from the beginning to the end. On the other hand, in the second embodiment, the integrated manufacturing design is performed for each manufacturing process. In this point, the second embodiment is different from the first embodiment. Other points are the same as the first embodiment. Therefore, those having the same functions as the first embodiment include:
The detailed description thereof is omitted by attaching the same reference numerals or corresponding reference numerals.

The main storage unit 1 of the first storage unit 13 of the present embodiment
31 stores the manufacturing specifications as a result of the integrated manufacturing design that has already been created for each manufacturing process in association with the product specifications and the manufacturing method specifications. The table group and the logic group 141 of the second storage unit 14 are stored for each manufacturing process. When manufacturing a product that has never been manufactured, the process-specific manufacturing design processing unit 151 uses the table group of the second storage unit 14 for each manufacturing process based on the product specification and manufacturing method specification of the product. Using the logic group 141 and the manufacturing method setting table 145, a manufacturing design for each manufacturing process for determining the operating conditions of each process is performed for each manufacturing process.

FIG. 7 is a flowchart for explaining the operation of the integrated manufacturing design processing system according to the second embodiment of the present invention. After determining the basic processing order using the processing order table, the control unit 11 sequentially performs the manufacturing design for each manufacturing process. First, a matching process is performed to determine whether the same product specifications and manufacturing method specifications as those input for the manufacturing process A are stored in the main storage unit 131 (step S).
11a). For products that have been built in the past, the results of integrated manufacturing design are stored for each manufacturing process,
The result of the manufacturing design is read (step S12a),
Move to the next process. As a result of performing the matching processing in step S11a, if the same one is not stored in the first storage unit, the control unit 11 sets the process-specific manufacturing design creation unit 15
And a command to newly perform a manufacturing design of the manufacturing process A is issued. The step-by-step manufacturing design creation section 151 stores the table group and the logic group 14 stored in the second storage section 14.
1. Based on the product specification and manufacturing method specification of this order using the manufacturing method setting table 145, a new manufacturing design is performed for the manufacturing process A to create a manufacturing specification (step S20a).

When a new manufacturing design is created as described above, the manufacturing specification as a result of the manufacturing design once becomes
It is stored in the temporary storage unit 130 (Step S21a).
In step S22a, the result of the manufacturing design is output on a screen or paper. In step S23a, it is checked whether or not the output result of the manufacturing design is normal. If there is an abnormality in the inspection, the process returns to step S20a and the manufacturing design is performed again. If the inspection is passed, the result of the manufacturing design is copied from the temporary storage unit 130 and stored in the main storage unit 131 in association with the product specification and the manufacturing method specification (step S24a).

The design of the manufacturing process B is performed in the same manner as in the case of the manufacturing process A. Step S
In step 11b, a match process is performed to determine whether the same product specifications and manufacturing specifications as those input for the manufacturing process B are stored in the first storage unit 13 (step S11).
b). If there is a result of the manufacturing design, the manufacturing specification is read (step S12b), and the process proceeds to the next processing.

Hereinafter, a manufacturing design is sequentially performed for each manufacturing process, and a manufacturing design is performed for all manufacturing processes to be used. Normally, products that have never been made in the past are products that have been made in the past, except that some manufacturing processes are different, and many other manufacturing processes are products that have been made before. Often the same as Even in such a case, in the conventional system, an integrated manufacturing design was performed from the beginning. On the other hand, in the present embodiment, only the manufacturing design of different manufacturing processes is performed, and for the same manufacturing process, integrated manufacturing design is performed by effectively utilizing the past manufacturing specifications of each manufacturing process. The integrated manufacturing design can be performed quickly compared to the system.

As described above, when the manufacturing design for each manufacturing process to be used is completed, the manufacturing specifications for each manufacturing process are put together to create a manufacturing specification for an integrated manufacturing design. Then, the data is output on paper as a manufacturing specification (Step S13), and a person in charge inspects each manufacturing process to see if it is within a predetermined range. For the integrated manufacturing design that has passed the inspection, the schedule is adjusted, and then the output unit 12
Is sent to a terminal computer that controls each manufacturing process via the. An integrated manufacturing design that does not pass the inspection is redone. Note that, in the case of the present embodiment, since this inspection has already been performed when the manufacturing design of each manufacturing process has been performed, the inspection here can be omitted.

With respect to the integrated manufacturing design created as described above, the production schedule for actual manufacturing is adjusted as in the first embodiment, and if there is a manufacturing process that is overloaded, Change the recipe of the related order,
Create a new integrated manufacturing design. In the present embodiment, a table group and a logic group are stored for each manufacturing process, an integrated manufacturing design is performed for each manufacturing process, and the result is stored for each manufacturing process. Therefore, when the production method of a certain order is changed after the production schedule is adjusted, for example, when the annealing process F1 is changed to the annealing process F2, in the present embodiment,
Since only the manufacturing design of the annealing step F needs to be redone, the manufacturing method can be changed easily and quickly compared to the first embodiment in which all the manufacturing designs from the beginning to the end are redone. Other operations and effects are the same as those of the first embodiment.

In the present embodiment, when a new integrated manufacturing design is performed, the result is stored in the first storage unit 13 in association with the product specification and the manufacturing method specification. Later, when the same order is received, the stored result of the integrated manufacturing design is read out and each manufacturing process is controlled, so compared to the conventional system that performed the integrated manufacturing design for each order, The results of the integrated manufacturing design once performed can be effectively used. In addition, by storing the results of past integrated manufacturing design in the first storage unit, even if a table or logic is changed by mistake, products that have been manufactured in the past can be stably manufactured. Therefore, the stability of the integrated manufacturing design can be improved as compared with the conventional one.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention. For example, in the above-described embodiment, the case where the present invention is used in a line for manufacturing a steel product has been described. However, the present invention is not limited to this, and all the manufacturing processes performed through a plurality of manufacturing processes are performed. Can be used for line.

[0053]

As described above, according to the present invention, when a first product is manufactured, an integrated manufacturing design is performed by a manufacturing design creating means based on the product specification, and the result is associated with the product specification.
