Next, the details of the data processing method in the data processing apparatus 1 will be described. FIG. 3 is a flowchart of a data processing method.

First, it is determined whether or not the manufacturing data indicating the time change of the measurement data in the rolling process is input in one file for each rolling process in one cycle (step S11). The time-series data creation unit 20 determines whether or not the input manufacturing data is input in one file for each rolling process in one cycle. If it is determined that the manufacturing data is input in one file for each rolling process in one cycle, the process proceeds to step S12. If it is determined that the manufacturing data is not input in one file for each rolling process in one cycle, the process proceeds to step S13.

In step S13, the time-series data creation unit 20 divides the manufacturing data of the rolling process into one file for each rolling process of one cycle. The time-series data creation unit 20 divides the manufacturing data of the rolling process into one file for each rolling process of one cycle, and then proceeds to step S12.

Next, it is determined whether or not the measurement data included in one file in the time-series data creation unit 20 is only the measurement data during the rolling process (step S12). The time-series data creating unit 20 determines whether or not the measurement data included in one file is only the measurement data during the rolling process of the metal material 11. When it is determined that the measurement data included in one file is only the measurement data during the rolling process of the metal material 11, the measurement data included in one file is output to the data division unit 31 as one time-series data, and the step is performed. Proceed to S14. If it is determined that the measurement data included in one file is not only the measurement data during the rolling process of the metal material 11, the process proceeds to step S15.

In step S15, the time-series data creation unit 20 deletes the measurement data before the start of the rolling process and the measurement data after the rolling process is completed from the measurement data included in one file. As a result, the measurement data included in one file is only the measurement data during the rolling process of the metal material 11, and one time-series data is created.

FIG. 4 is a characteristic diagram showing manufacturing data of the molding member 10 in the rolling process. In FIG. 4, the horizontal axis shows the data number of the rolling load value measured at the same time interval in the rolling process, and the vertical axis shows the rolling load value. The horizontal axis is shown in descending order of the data number of the rolling load value, and may be regarded as representing the passage of time. That is, FIG. 4 shows the time change of the rolling load value in the rolling process of one cycle.

The “measurement data before starting the rolling process” in step S15 is, for example, in the characteristic diagram shown in FIG. 4, as the data number increases in the section where the rolling load value is equal to or less than a certain value. Refers to the data in the section where the rolling load value becomes large (hereinafter referred to as "inside the section before the start of processing"). In step S15, the time-series data creation unit 20 deletes the measurement data in the section before the start of processing from the measurement data included in one file.

Further, the "measurement data after the rolling process is completed" in step S15 is, for example, in the characteristic diagram shown in FIG. 4, within a section where the rolling load value is equal to or less than a certain value, and the data number is large. It refers to the measurement data in the section where the rolling load value becomes smaller as it becomes (hereinafter referred to as "inside the section after processing"). In step S15, the time-series data creation unit 20 deletes the measurement data in the post-processing section from the measurement data included in one file. As a result, the measurement data included in one file of the time-series data creation unit 20 is only the measurement data in the processing section shown in FIG.

FIG. 5 is a characteristic diagram showing measurement data in the section being processed. The measurement data in the processing section shown in FIG. 5 is only the measurement data during the rolling processing of the metal material 11. The time-series data creation unit 20 outputs the measurement data in the section being processed as time-series data to the data division unit 31.

Next, it is confirmed that the time series data is the measurement data during the rolling process of one cycle (step S14). In step S14, the data division unit 31 confirms that the time-series data output by the time-series data creation unit 20 is only the measurement data during one cycle of rolling processing.

Next, it is determined whether or not the data of the feed rate of the metal material 11 in the rolling step is input (step S16). The processing speed determination unit 32 determines whether or not data on the feed rate of the metal material 11 has been input from the rolling control unit, and outputs the determination result to the data division unit 31. If it is determined that the feed rate data of the metal material 11 has not been input, the process proceeds to step S17. If it is determined that the feed rate data of the metal material 11 has been input, the process proceeds to step S18.

In step S17, the time series data is evenly divided by the number of products of the forming member 10 processed in one cycle of rolling process. The data division unit 31 divides the time-series data created by the time-series data creation unit 20 by the number of products of the molding member 10 processed in one cycle of the rolling process, and measures measurement data or a set of measurement data at the same time interval. Create the divided data that is. As a result, the number of measurement data included in each of the divided data is the same.

FIG. 6 is a characteristic diagram illustrating a division process of time series data. FIG. 6 shows an example when the time series data is divided by the number of products of the molding member 10 processed in one cycle of rolling process. The dotted frame D shown in FIG. 6 schematically shows the range of measurement data included in one divided data.

FIG. 6A is an example of the division process in step S17. For example, when the number of products of the molding member 10 processed in one cycle of the rolling process is 200 and the total number of time-series data is 3000, the measurement data of 3000 points is divided into 15 points each. The measurement data of 15 points is regarded as one divided data. As a result, 200 divided data having 15 measurement data are generated.

Further, in step S18, it is determined whether or not the feed rate of the metal material 11 in the rolling step is constant. The processing speed determination unit 32 determines whether or not the feed rate of the metal material 11 is constant from the data of the feed rate of the metal material 11 stored in the processing speed determination unit 32, and determines whether or not the determination result is a data division unit. Output to 31. If it is determined that the feed rate of the metal material 11 is constant, the process proceeds to step S17. If it is determined that the feed rate of the metal material 11 is not constant, the process proceeds to step S19.

In step S19, the time series data is divided by the number of products of the molding member 10 processed in one cycle of the rolling step according to the change in the feed rate of the metal material 11. At this time, the number of measurement data included in the divided data varies depending on the change in the feed rate of the metal material 11.

FIG. 6B is an example of the division process in step S19. For example, it is assumed that the number of products of the molding member 10 processed in one cycle of rolling process is 200, and the total number of time series data is 3000. Further, it is assumed that the feed rate of the metal material 11 in the first half of the rolling process is twice the feed rate of the metal material 11 in the second half. In this case, the measurement data corresponding to the 100 molding members 10 processed in the first half of the rolling process among the 200 molding members 10 is 2000 points, which is the smaller data number of the 3000 measurement data points. Therefore, one divided data is obtained by dividing the measurement data of 2000 points in the first half of the time series data by 20 points. Further, among the 200 molded members 10 that have been collectively processed, the measurement data corresponding to the 100 molded members 10 that have been processed in the latter half of the rolling process is 1000 points of the measurement data of 3000 points, whichever has the larger data number. It becomes. Therefore, the measurement data of 1000 points in the latter half of the time series data is divided into 10 points each to obtain one divided data. As a result, the number of data included in the division data of each part of the metal material 11 corresponding to the molded member 10 processed in the first half is included in the division data of each part of the metal material 11 corresponding to the molding member 10 processed in the second half. It will be twice the number of data.
As described above, in step S19, the data division unit 31 is the data of the measurement data included in the respective division data for the total number of measurement data of the time series data according to the determination result output by the processing speed determination unit 32. Change the ratio of numbers.

Next, the identification label of the molding member 10, the division data, and the two individual data are associated with each other according to the molding order of the molding member 10 in the molding step (step S20). Specifically, an identification label attached to each of the plurality of molding members 10 completed through the molding step is input to the association processing unit 50. At this time, the association processing unit 50 is stored in the division data stored in the division data storage unit 41, the individual data of the cutting process stored in the cutting data storage unit 42, and the molding data storage unit 43. The individual data of the molding process is read from each storage unit. The association processing unit 50 associates the input identification label with the division data corresponding to the molding member 10 of the identification label, the individual data of the cutting process, and the individual data of the molding process, and creates the analysis data. .. The association processing unit 50 outputs the created analysis data to the analysis processing unit 60.

In step S20, the association processing unit 50 is rolled when the order in which each part of the metal material 11 is processed in the rolling step and the order in which the plate-shaped member 15 is processed in the cutting step and the forming step are the same. Identification labels, division data, and individual data are associated so that each part of the metal material 11 in the order of rolling and the plate-shaped member 15 in the order of being cut and molded is associated with each other. When the order in which each part of the metal material 11 is processed in the rolling process and the order in which the plate-shaped member 15 is processed in the cutting process and the forming process are the same, for example, the thin plate 14 is cut and formed in the order of rolling. This is the case.

Further, in step S20, the association processing unit 50 rolls when the order in which each part of the metal material 11 is processed in the rolling step and the order in which the plate-shaped member 15 is processed in the cutting step and the forming step are reversed. Identification labels, division data, and individual data so that each part of the metal material 11 in the order of processing is associated with the plate-shaped member 15 in the order opposite to the order of cutting and forming. To associate. When the order in which each part of the metal material 11 is processed in the rolling process and the order in which the plate-shaped member 15 is processed in the cutting process and the forming process are reversed, for example, the rolled thin plate 14 is rolled. This is the case where the roll-shaped thin plate 14 is wound and then cut from the last wound end to form the roll-shaped thin plate 14.

FIG. 7 is a characteristic diagram illustrating the process of associating the divided data. The dotted frame shown in FIG. 7 shows the range of measurement data included in one divided data. Further, in FIG. 7, the identification label numbers are shown as label number 1, label number 2, and label number 3 in the order in which the molding member 10 is molded in the molding step.

FIG. 7A shows the divided data in the case where the order in which each part of the metal material 11 is processed in the rolling step and the order in which the plate-shaped member 15 is processed in the cutting step and the forming step are the same in step S20. Shows the relationship with the identification label. As shown in FIG. 7A, the association processing unit 50 associates the divided data with the identification label so that the number of the identification label increases in order from the divided data including the measurement data having the smaller data number.

Further, FIG. 7B shows division in the case where the order in which each part of the metal material 11 is processed in the rolling step and the order in which the plate-shaped member 15 is processed in the cutting step and the forming step are reversed in step S20. Shows the relationship between the data and the identification label. As shown in FIG. 7B, the association processing unit 50 associates the divided data with the identification label so that the number of the identification label increases in order from the divided data including the measurement data having the larger data number.

As described above, in step S20, analysis data is created according to the relationship between the order of processing in the rolling process and the order of processing in the cutting process and the forming process.

Next, the manufacturing process of the molded member 10 is analyzed using the analysis data (step S21). The analysis processing unit 60 uses the analysis data output by the association processing unit 50 to perform statistical analysis for deriving, for example, the relationship between the performance of the molding member 10 and the measurement data of each small process.

According to the data processing apparatus 1 of the present embodiment described above, the division processing unit 30 divides the time series data obtained in the rolling process by the number of products of the plurality of molding members 10 included in the metal material 11. The association processing unit 50 corresponds to the identification label for identifying each molded member 10 and the molded member 10 of the identification label among the divided data which is a part of the time series data divided into the number of products of the molded member 10. Associate with the divided data to be used. As a result, a part of the time-series data can be associated with the identification label of the molding member 10 corresponding to the part of the time-series data. Therefore, the plurality of molding members included in the metal material 11 using the time-series data. It is possible to create analysis data capable of analyzing the difference between the ten.

Further, according to the data processing apparatus 1 of the present embodiment, the association processing unit 50 includes division data obtained in the rolling process, individual data obtained in the cutting process, individual data obtained in the molding process, and an identification label. To associate. As a result, the association processing unit 50 can associate the identification label with the division data corresponding to the molding member 10 of the identification label and the two individual data, so that the measurement data obtained in the manufacturing process of the molding member 10 is cut off. Can be associated with an identification label.

Further, according to the data processing apparatus 1 of the present embodiment, as described in step S19, even if the number of data corresponding to one product changes depending on the feed rate of the metal material 11 in the rolling process, the division processing unit 30 Divides the time series data so as to correspond to one molding member 10. As a result, the association processing unit 50 can reliably associate the identification label of one molding member 10 with the division data corresponding to the one molding member 10.

Further, according to the data processing apparatus 1 of the present embodiment, the association processing unit 50 has the order in which each part of the metal material 11 is processed in the rolling process, and the plurality of plate-shaped members 15 corresponding to each part in the molding process. The division data is associated with the individual data of the molding process according to the relationship with the order in which the is processed. This makes it possible to reliably associate the corresponding divided data and the individual data with one identification label.

Further, according to the data processing apparatus 1 of the present embodiment, the time-series data creation unit 20 shows only the time change of the measurement data during the rolling process in the rolling process of one cycle from the measurement data output by the rolling control unit. Create the time series data that has been created. As a result, it is possible to exclude measurement data unnecessary for evaluating the difference between the plurality of molded members 10 from the time series data, so that the accuracy of the divided data associated with the molded members 10 can be improved.
