Description

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 In steel manufacturers, cold-rolled steel sheets, surface-treated steel sheets, electromagnetic steel sheets, stainless steel sheets, rails, seamless pipes,
We manufacture a large variety of products such as spiral tubes and steel sheet piles. These products are 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, depending on the type.

FIG. 5 is a diagram for explaining a conventional integrated manufacturing design processing system. Normally, when an order is received from a customer, a steel product is first designed in the head office by assigning necessary material values such as the material of the product and a tensile test according to the order (step S51). Data resulting from the product design performed at the head office is sent to the steel works. 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 to be passed and the manufacturing schedule (production plan) ) And a manufacturing design for determining operating conditions of the manufacturing process is performed (step S52). 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 this integrated manufacturing design is output to each manufacturing process necessary for manufacturing a product (step S5).
3) 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. In this case, for example, when there are a plurality of hot rolling steps, it is necessary to design which hot rolling step to use. The integrated manufacturing design at a steel mill is usually batch-processed because the number of manufacturing design items increases.

In the conventional integrated manufacturing design, information necessary for each manufacturing process is created 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] When a special order is placed, the data in a specific table is rewritten in order to fulfill the order, an integrated manufacturing design for the order is performed, and then the work of restoring the rewritten data is performed. When such data is rewritten, another record may be erroneously rewritten, and it may not be possible to normally perform an integrated manufacturing design for an order received with the same specification.
As described above, the conventional integrated manufacturing design processing system has a problem of lack of stability.

Further, when an order is corrected, a manufacturing process is changed, a manufacturing condition is changed, etc., in the integrated manufacturing design once designed, the integrated manufacturing design is restarted from the beginning each time. For example, even if an integrated manufacturing design has already been created, if one hot rolling process subsequently fails, another hot rolling process must be used. In this case, it is necessary to input a new product specification again, and to perform the integrated manufacturing design from the converter process to the packing process again. For this reason, there are adverse effects such as a delay in the production instruction.

[0008] In addition, as a result of conducting an integrated manufacturing design and inspecting, it is found that an ordered product cannot be manufactured. If the cause is investigated, if the data in a certain table is found to be incorrect, the data is corrected. Then, the integrated manufacturing design is performed once again, and the result is output to paper and the inspection is performed again. For this reason, there is a problem that it takes time to correct the integrated manufacturing design.

The present invention has been made on the basis of the above circumstances, and it is possible to effectively utilize the data of the past integrated manufacturing design, to improve the stability of the integrated manufacturing design, and to further improve the speed. An object of the present invention is to provide an integrated manufacturing design processing system capable of performing an integrated manufacturing design.

[0010]

According to a first aspect of the present invention, there is provided an integrated manufacturing design processing system for managing and operating a plurality of manufacturing processes based on product specifications. An integrated manufacturing design processing system for performing a design, based on the product specifications, a process-specific manufacturing design creating means for performing a manufacturing design for each manufacturing process using a table and logic provided for each manufacturing process, A storage unit for storing the result of the manufacturing design created by the process-specific manufacturing design creation unit in association with the product specification for each manufacturing process, and a product specification that matches the input product specification is stored in the storage unit Is determined for each of the manufacturing steps, and if it is stored, the result of the manufacturing design of the matching product specification is read out; Performs integrated manufacturing design by causing the production design, it is characterized in that it comprises processing means for outputting the results collectively or for each manufacturing process, the.

Using a table and logic provided for each manufacturing process, a manufacturing design is performed for each manufacturing process.
By storing the results in association with the product specifications for each manufacturing process, it is possible to call up the results of the manufacturing design for each manufacturing process and perform correction work. Modification work of the design becomes easy. That is, when there is an error in the newly created integrated manufacturing design, only the result of the newly created manufacturing process needs to be checked, so that an error in the integrated manufacturing design can be found easily and in a short time.

Also, it is determined for each manufacturing process whether or not a product specification that matches the input product specification is stored in the storage means. If the product specification is stored, the result of the manufacturing design of the matched product specification is read out. By making the manufacturing design creation process by process only when it is not memorized, the manufacturing design created in the past can be used effectively, and the design time can be reduced compared to the conventional integrated manufacturing design. It can be greatly reduced.

Further, in the case of storing the data of the manufacturing specification as a result of the manufacturing design, storing the manufacturing specification for each manufacturing step eliminates the storage of duplicated data and efficiently stores the data in the storage means. can do.

In the present embodiment, the product to be finally finished is designed at the head office, and the resulting product specification is sent to each steelworks. 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, And design a production plan. For example, when the hot rolling step D and the cold rolling step E are used, the thickness of the hot rolling step D is extended to a certain number of millimeters, and the thickness of the cold rolling step E is set to several mm. Then, a manufacturing design for generating necessary data in each manufacturing process required for that 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 of the present embodiment includes an input unit 10 such as a keyboard for inputting product specifications, and a control unit for controlling integrated manufacturing design based on the input product specifications. An output unit 12 for outputting a result of the integrated manufacturing design performed by the control unit 11, a first storage unit 13 for storing a result of the integrated manufacturing design in association with a product specification for each manufacturing process, A second storage unit 14 for storing a table group and a logic group, and a step of performing manufacturing design of each manufacturing process with reference to the table group and the logic group stored in the second storage unit 14 based on an instruction from the control unit 11 The separate manufacturing design creation unit 15, the management unit 16 for changing and managing the contents of the table group and the logic group, and the first storage unit 13 when the contents of the table group or the logic group are changed. Product Specifications Based redo the manufacturing design of integrated manufacturing design or the corresponding part of the manufacturing process, and a regenerating unit 17 for storing the result in the first storage unit.

The input unit 10 inputs the product specifications to the server computer using a keyboard or the like based on the product specifications sent from the head office. 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, on a printer or the like, the manufacturing specifications that are the result of the integrated manufacturing design or the manufacturing specifications that are the result of the manufacturing design performed for each manufacturing process, or connects a communication line or the like to each manufacturing process. Send using.

The first storage unit 13 stores the results of the integrated manufacturing design that has already been created for each manufacturing process in association with the product specifications. For example, with the main items of the product specifications as key items, the corresponding manufacturing specifications
Stored for each manufacturing process. The table group 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 an item of each table, for example, in the case of a material table, a product standard, a user name, a product size, hardness, a rough skin, a tensile test,
Bending test, grain size, workability test, etc. are provided. In addition, logic means if and w for determining processing conditions.
This is written using a computer language (e.g., COBL) such as hill. For example, when a certain product has a plurality of manufacturing methods, it is used to determine a manufacturing method that meets conditions.

When manufacturing a product which has never been manufactured, the process-specific manufacturing design creating unit 15 stores the product in the second storage unit 14 for each manufacturing process based on the product specifications of the product. Using the table group and the logic group, a manufacturing design for each manufacturing process for determining operating conditions, a production plan, and the like of each manufacturing process is performed. The management unit 16 changes and manages a table group and a logic group. For example, when a record is changed, a range affected by the change is automatically displayed, or the use status is managed in a record unit of a table group. It also manages the date and time when the content was changed, the reason, the processor, etc.

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 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, each item of the new and old integrated manufacturing designs can be compared, and the results can be displayed in a list 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.

Next, the operation of the integrated manufacturing design processing system of this embodiment will be described with reference to FIG. First,
A case where an order is made for a product that has been made in the past will be described. When a product specification created at the head office for such an order is input via a keyboard or a communication line (step S10), the control unit 11 determines a basic processing order, and then sequentially determines each manufacturing process. Perform manufacturing design. Then, first, a matching process is performed to determine whether or not the same product specifications as those input for the manufacturing process A are stored in the first storage unit 13 (step S11a).
For products that have been manufactured in the past, the results of the integrated manufacturing design are stored for each manufacturing process, so the results of the manufacturing design are read out (step S12a), and the process proceeds to the next process. Similarly, in step S11b, the same product specifications as those input for the manufacturing process B are stored in the first storage unit 1.
3 is performed (step S11b). Then, the manufacturing specification as a result of the manufacturing design is read out (step S12b), and the process proceeds to the next processing. In this way, the manufacturing design is performed for each manufacturing process, and when the manufacturing design for all the manufacturing processes is completed, the manufacturing specifications for each manufacturing process are combined to create a manufacturing specification for an integrated manufacturing design, and the manufacturing specifications are created. Is output to paper via the output unit 12 (step S13), and the manufacturing specifications are sent to the terminal computer that controls each manufacturing process via the output unit 12 (step S14).

In each of the manufacturing processes from the converter process A to the packing process I, conditions required for operation are set by terminal computers provided in each of the devices based on the received manufacturing specifications, and each device is operated. And perform the processing. As described above, in the present embodiment, since the result of the integrated manufacturing design created in the past is stored, the products having the same quality can be reliably manufactured quickly in the products created in the past. .

Next, a case where an order is placed for a product which has not been made in the past will be described. When such an order is input (step S10), the control unit 11 determines a basic processing order and performs a manufacturing design for each manufacturing process sequentially in the same manner as described above. First, the same product specifications as those input for the manufacturing process A are stored in the first storage unit 13.
(Step S11a). If it is stored, the result of the manufacturing design is read out (step S12a), and the process proceeds to the next step. As a result of performing the matching process, if the same one is not stored in the first storage unit, the control unit 11 sends a signal to the process-specific manufacturing design creating unit 15 to newly perform the manufacturing design of the manufacturing process A. Instructions. The process-specific manufacturing design creation unit 15 uses the table group and the logic group stored in the second storage unit 14 based on the product specification of this order,
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 is output to a screen or paper in step S21a, and
At 22a, the result is stored in the first storage unit 13 in association with the product specification. Here, if necessary, an inspection may be performed as to whether or not the manufacturing design in the manufacturing process A has been correctly performed, and only the manufacturing specifications that have passed the inspection may be registered. Then, the manufacturing design of the next manufacturing process B is performed (step S11).
b). The design of the manufacturing process B is performed in the same manner as in the case of the manufacturing process A. Hereinafter, the manufacturing design is sequentially performed for each manufacturing process, and the manufacturing design is performed for all the 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.

Hereinafter, the manufacturing design will be specifically described by taking the case of designing the material of the steel material as an example. The manufacturing design of the steel material is performed using a material table (and logic) prepared for each manufacturing process. Based on the product specifications sent from the head office, read the records that match the necessary conditions by referring to the table for each manufacturing process to be used, and the data necessary to operate the manufacturing process for each manufacturing process To get. Even the same surface-treated steel sheet has a slightly different material depending on the user, and therefore, the product specification of each order includes a user name in addition to the product standard. Based on the product specifications, the manufacturing processes to be used and the operating conditions in each of the manufacturing processes to be used are carefully designed in accordance with the specifications.

Further, when designing the material of the surface-treated steel sheet, first, what components of the steel to be manufactured in the converter are determined using a group of tables based on the product specifications.
This generates data required in the converter process, such as the raw materials used, the type of smelting means, and the ratio of carbon. The material of the final product is roughly determined in this converter process,
It also changes greatly in the annealing step, rolling step, etc. 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 is rolled into a cold-rolled steel sheet P4 of 0.8 mm in a cold rolling step E, and further annealed in a first annealing step F1,
A plating process of 0.01 mm is performed in a plating process G, and the surface shape is adjusted in a skin pass process H to produce a surface-treated steel plate P5 having a thickness of 0.82 mm. 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 for each manufacturing process.

As described above, when the manufacturing design for each of the manufacturing processes 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. The data is output as a manufacturing specification on a screen or paper (step S13), and a person in charge inspects each manufacturing process to see if it is within a predetermined range. The integrated manufacturing design that has passed the inspection is sent to a terminal computer that controls each manufacturing process via the output unit 12 (Step S1).
4). An integrated manufacturing design that does not pass the inspection is redone. The reason why the wrong integrated manufacturing design is output is that an error occurs when the specification value of the product specification is 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. Such an inspection may be performed when the manufacturing design of each manufacturing process is performed as described above and before shifting to the design of the next manufacturing process.

Next, the processing in the case where the table group and the logic group are changed will be described. When a certain record of a table group is changed by the management unit 16, for example, a product specification of an integrated manufacturing design created using old data of the changed record is searched. If there is a corresponding product specification, it is read out, a new integrated manufacturing design is performed using the changed table group and logic group, and 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. When the table group or the logic group is changed, the management unit 16 manages the history of when and who changed the table group and the logic group. Used to grasp.

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. 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. Moreover,
By storing the results of the past integrated manufacturing design in the first storage unit, even if the table or logic is changed by mistake, stable production can be performed for products that have been manufactured in the past. Therefore, the stability of the integrated manufacturing design can be improved as compared with the conventional one.

In addition, for the data already stored in the first storage unit 13, the inspection process of the person in charge is not required, so that the labor can be reduced. Further, in the present embodiment, when the table or the logic is changed, the already stored result of the integrated manufacturing design is regenerated, so that the table or the logic can be flexibly changed.

Further, conventionally, one integrated manufacturing design was performed for all the manufacturing processes, and one custom manufacturing specification was stored and output. Therefore, the data amount became enormous, and the created manufacturing specification was It was not easy to separate them for each manufacturing process. In addition, in the conventional system, even if the manufacturing design of a certain manufacturing process has exactly the same contents in two orders with different specifications, an integrated manufacturing design of each manufacturing process is newly performed for each order unit. . On the other hand, in the present embodiment, a manufacturing design is performed for each manufacturing process, and a manufacturing specification can be stored and output for each manufacturing process.
It is possible to output a compact manufacturing specification document including only necessary manufacturing steps. Further, the manufacturing instruction can be given not only by the integrated manufacturing design, but also by performing the manufacturing design for each manufacturing process for each process. Also,
Since the manufacturing design is performed for each manufacturing process and the results are stored, if there is a correction of order, a change in the manufacturing process, a change in manufacturing conditions, etc. for the integrated manufacturing design once designed, As a result of conducting an integrated manufacturing design and inspecting, it is found that the ordered product cannot be manufactured, and if the cause is investigated, even if the data in a certain table is found to be incorrect, it can be promptly dealt with. That is, in such a case, the integrated manufacturing design is corrected by performing only the manufacturing design of the related manufacturing process and correcting the manufacturing specification of the manufacturing process, instead of performing the new integrated manufacturing design again. be able to. Therefore, it is possible to quickly correct the integrated manufacturing design.

In addition, some orders may differ only in the specification of the final packing process, for example, and all other manufacturing processes may be the same. In this case, if the integrated manufacturing designs for the two orders are separately stored, the storage capacity becomes enormous. However, in this embodiment, for each manufacturing process,
By performing manufacturing design and storing and utilizing the results, redundant storage of manufacturing specifications can be eliminated, and the storage means can be used efficiently.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible 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.

Further, in the above embodiment, the case where the product design is performed at the head office has been described, but the product design may be performed at each steelworks. Furthermore, in the above-described embodiment, the case where the data of the manufacturing specification as a result of the integrated manufacturing design is stored as one set of data in one first storage unit, but the data of the manufacturing specification is stored in each manufacturing process. Data that may be changed at the site and data that should not be changed at each site may be stored separately. As a result, each data can be changed in a desirable and appropriate department.

[0037]

As described above, according to the present invention, when a first product is manufactured, a manufacturing design for each manufacturing process is made as necessary by the manufacturing design creating means for each process based on the product specifications. The result is output and stored in the storage means, and when a product that has been manufactured in the past is manufactured, the result of the manufacturing design stored in the storage means is read out and output for each manufacturing process. In addition to being able to effectively use the integrated manufacturing designs created in the past, it is also possible to improve the stability of the integrated manufacturing designs, and the manufacturing design with the same product specifications is stored in the storage means for each manufacturing process. Judgment whether or not it is done, if it is memorized, read out the result of the manufacturing design of the matching product specification, and perform the manufacturing design of the manufacturing process only when it is not memorized. It is possible to provide a consistent manufacturing design processing system capable of shortening the time required for forming the design.
