[0010] Patent Document 4: Japanese Patent Publication No. 2008-34817 (published on February 14, 2008) Summary of the invention

[0011] Problem that the invention aims to solve

[0012] In order to manage a manufacturing line formed by multiple processes, a technology for properly managing the status of each process is sought. However, in Patent Document 1, the measured values ​​obtained by measuring the measurement items of each process of the manufacturing line are not displayed according to each process, but according to production-related information, safety-related information, and product quality information, so it is impossible to manage the status of each process. In Patent Documents 2 and 3, the multiple modules of the reaction process guidance list screen only show the abnormal content of each process of the manufacturing line, so the manager cannot grasp the status of each process. In Patent Document 4, although a list of the status of the products obtained in each process of the manufacturing line is displayed, it is difficult to grasp the status of the process based on the list. In addition, in Patent Document 4, although a detailed screen of the product is displayed when the area of ​​the statistical chart of the list is clicked, the area is separated from the area showing the status of the product obtained in the process, so it is difficult for the manager to grasp the status of each process. Therefore, in the prior art such as these Patent Documents 1 to 4, it is impossible to properly manage the status of each process constituting the manufacturing line.

[0013] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to realize a management method and a management device capable of appropriately managing the status of each process constituting a manufacturing line.

[0014] Solutions for solving problems

[0015] In order to solve the above-mentioned problem, a management method according to one embodiment of the present invention is a management method for managing a manufacturing line formed by a plurality of processes. The management method includes the following processing: a first display processing, in which a first screen representing the status of each process is displayed on a display by a first indicator group formed by indicators corresponding to each process; and a second display processing, in which a second screen representing the status of a specific process in more detail is displayed on the display. The indicator corresponding to the specific process in the first indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the second screen.

[0016] According to the above configuration, the indicator corresponding to the specific process in the first indicator group in the first screen functions as a GUI element for causing the screen displayed on the display to transition from the first screen to the second screen showing the status of the specific process in more detail.

[0017] Thus, compared with the structure in which the screen displays production-related information, safety-related information, and product quality information instead of each process as in the technology described in Patent Document 1, the structure in which only the abnormal contents of each process are displayed on the screen as in the technologies described in Patent Documents 2 and 3, and the structure in which a table of the status of products obtained in each process of the manufacturing line is displayed on the screen as in the technology described in Patent Document 4, the status of each process constituting the manufacturing line can be appropriately presented to the manager. As a result, the status of each process constituting the manufacturing line can be appropriately managed.

[0018] A management method according to one embodiment of the present invention is a management method for managing a manufacturing line formed by a plurality of processes. The management method includes the following processing: a first display processing, in which a first screen is displayed on a display, which indicates the status of each process by a first indicator group composed of indicators corresponding to each process, and indicates the operating status of a manufacturing device used in each process by a second indicator group composed of indicators corresponding to each process; a second display processing, in which a second screen is displayed on the display, which indicates the status of a specific process in more detail; and a third display processing, in which a third screen is displayed on the display, which indicates the operating status of a manufacturing device used in a specific process in more detail. The indicator corresponding to a specific process in the first indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the second screen. The indicator corresponding to a specific process in the second indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the third screen.

[0019] According to the above structure, the indicator of the first screen functions as a GUI for migrating the screen displayed on the display from the first screen to the second screen, or as a GUI for migrating the screen displayed on the display from the first screen to the third screen. Thus, the manager can grasp the status of each process constituting the manufacturing line or the status of the manufacturing device used in each process.

[0020] In addition, the process of displaying the detailed status in the second display processing (recorded as a "specific process") and the process of displaying the detailed status in the third display processing (recorded as a "specific process") may be the same process or different processes.

[0021] Effects of the Invention

[0022] According to one embodiment of the present invention, it is possible to realize a management method and a management device capable of appropriately managing the status of each process constituting a manufacturing line. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] <Implementation Method 1>

[0041] Below, refer to Figures 1 to 12 A management method for managing a manufacturing line 3 formed of a plurality of processes by the management system 1 according to the present embodiment will be described. Before describing the management method, the management system 1 according to the present embodiment will be described first.

[0042] 〔Management System 1〕

[0043] Figure 1 1 is a block diagram showing the structure of the management system 1 according to the first embodiment. Figure 1 As shown, the management system 1 is composed of a management device 2 and a manufacturing line 3. In the management system 1, the manager monitors the status of each process constituting the manufacturing line 3 by means of a screen (for example, a WEB screen) output from the management device 2 to the output device 28, thereby managing the status of each process constituting the manufacturing line 3.

[0044] [Management device 2]

[0045] like Figure 1As shown, the management device 2 is a computer having a main memory 21, a controller 22, an auxiliary memory 23, a communication interface 24, and an input / output interface 25. The main memory 21, the controller 22, the auxiliary memory 23, the communication interface 24, and the input / output interface 25 are connected to each other via a bus 26. As the controller 22, for example, a single or multiple microprocessors, a single or multiple digital signal processors, a single or multiple microcontrollers, or a combination thereof can be used. As the main memory 21, for example, a single or multiple semiconductor RAMs (random access memories) can be used. As the auxiliary memory 23, for example, a single or multiple HDDs (Hard Disk Drives), a single or multiple SSDs (Solid State Drives), or a combination thereof can be used. In addition, part or all of the auxiliary memory 23 may also be a storage device on a network connected via the communication interface 24. The communication interface 24 is connected to the manufacturing line 3 via a wired or wireless LAN (Local Area Network) 1001 (for example, Ethernet (registered trademark)). As the input / output interface 25 , for example, a USB (Universal Serial Bus) interface, a short-distance communication interface such as infrared or Bluetooth (registered trademark), or a combination thereof can be used.

[0046] The input / output interface 25 is connected to, for example, an input device 27 and an output device 28. As the input device 27, for example, a keyboard, a mouse, a touch panel, a microphone, or a combination thereof can be used. As the output device 28, for example, a display, a printer, a speaker, or a combination thereof can be used. In addition, the management device 2 may also be equipped with a keyboard and a touch panel functioning as the input device 27 and a display functioning as the output device 28, as in a notebook computer. In addition, the management device 2 may also be equipped with a touch panel functioning as the input device 27 and the output device 28, as in a smartphone or a tablet computer.

[0047] The auxiliary memory 23 stores a program P0 for causing the controller 22 to execute each process included in the management method. The controller 22 expands the program P0 stored in the auxiliary memory 23 on the main memory 21, and executes each process included in the management method according to the program P0 expanded on the main memory 21. In addition, the auxiliary memory 23 stores various data that the controller 22 refers to in order to execute each process included in the management method. For details of each process included in the management method, use Figure 2 I will describe it later.

[0048] In addition, in the above example, the controller 22 is described as executing each process included in the management method according to the program P0 stored in the auxiliary memory 23 as the internal storage medium, but it is not limited to this. That is, the controller 22 may execute each process included in the management method according to the program P0 stored in the external recording medium. In this case, as the external recording medium, a computer-readable "non-transitory tangible medium" such as a magnetic tape, an optical disk, a card, a semiconductor memory, or a programmable logic circuit may be used. Alternatively, the following method may be used: the controller 22 implements each process included in the management method according to the program P0 obtained from the network connected via the communication interface 24. In this case, as the network, for example, the Internet, a wired LAN (Local Area Network), a wireless LAN, or a combination of at least part of them may be used.

[0049] 〔Manufacturing Line 3〕

[0050] like Figure 1 As shown, the manufacturing line 3 is equipped with a sand processing device M1, a molding device M2, a core device M3, a melting and pouring device M4, a cooling and conveying device M5, and a post-processing device M6. The sand processing device M1 performs sand processing among the multiple processes constituting the manufacturing line 3. The molding device M2 performs molding. The core device M3 puts a core into the managed object. The melting and pouring device M4 performs melting and pouring. The cooling and conveying device M5 performs cooling and conveying. The post-processing device M6 performs post-processing. Sand processing, molding, core, melting and pouring, cooling and conveying, and post-processing are well known as the multiple processes constituting the manufacturing line 3 for manufacturing castings, etc., so their description is omitted here. In addition, the manufacturing line 3 here is a line for manufacturing castings, etc., but is not limited to these.

[0051] In addition, the managed objects refer to the objects that are processed or used in each process, for example, in sand processing, the managed objects refer to regenerated sand and mixed sand, etc. In molding, the managed objects refer to molds and mixed sand, etc. In cores, the managed objects refer to molds and cores, etc. In melting and pouring, the managed objects refer to molten metal and molds, etc. In cooling and conveying, the managed objects refer to castings (products), molten metal and molds, etc. In post-processing, the managed objects refer to molds and castings (products), etc. However, the above-mentioned processes and managed objects are just examples, and each process can be a plurality of processes that constitute the manufacturing line 3, and the managed objects can be objects that are processed or used in each process.

[0052] The sand processing equipment M1, the molding equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5 and the post-processing equipment M6 are equipped with sensors C1 to C6 corresponding to each device, controllers P1 to P6 corresponding to each device, communication interfaces 31 to 36 corresponding to each device, and multiple manufacturing devices (not shown).

[0053] The controllers P1 to P6 control the manufacturing devices in the equipment corresponding to each controller among the sand processing equipment M1, the mold making equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5, and the post-processing equipment M6. Thus, the controllers P1 to P6 control the sand processing equipment M1, the mold making equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5, and the post-processing equipment M6. As an example, the controllers P1 to P6 are PLC (Programmable Logic Controller) controllers that operate according to a program for controlling each manufacturing device in the sand processing equipment M1, the mold making equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5, and the post-processing equipment M6. The controllers P1 to P6 obtain information indicating the status of each manufacturing device in the sand processing equipment M1, the mold making equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5, and the post-processing equipment M6. As an example, the information indicating the status of each manufacturing device is the power supply status and operation status of each manufacturing device in the sand processing equipment M1, the molding equipment M2, the core equipment M3, the melting and pouring equipment M4, the cooling and conveying equipment M5, and the post-processing equipment M6, and the information of each device measured by the sensors C1 to C6 connected to the controllers P1 to P6 by wire or wirelessly, etc., but is not limited to these. In addition, the controllers P1 to P6 obtain the information of each device through the output signals input from the sensors C1 to C6.

[0054] Furthermore, the controllers P1 to P6 are connected to the communication interface 24 of the management device 2 via the communication interfaces 31 to 36 corresponding to the respective devices and the LAN 1002 .

[0055] 〔Management methods〕

[0056] The management method involved in this embodiment includes a first display process, a second display process, a third display process and a fourth display process. Figure 2 to Figure 12 The details of the management method of this embodiment will be described. Figure 2 This is a screen transition diagram showing the transition of the screen generated by the management device 2 according to the first embodiment. Figure 3 to Figure 12 This is a diagram showing an example of a screen generated by the management device 2 according to the first embodiment.

[0057] (First Display Process and Second Display Process)

[0058] like Figure 3 As shown, the controller 22 of the management device 2 displays a top screen (first screen) G1 including a first indicator group I1 and a screen transition area group A1 on the display of the output device 28 (first display process). The first indicator group I1 is an indicator corresponding to each of the multiple processes constituting the manufacturing line 3, and is composed of indicators that generally show the status of the corresponding process.

[0059] In addition, the controller of the management device 2 displays a more detailed display of the Figure 3 A second screen (for example, Figure 4 and Figure 5 That is, the controller 22 of the management device 2 displays the information obtained by the control on the display of the output device 28. Figure 3 The first indicator group I1 shown on the right side of is operated to migrate from the top-level screen G1 to the second screen.

[0060] Here, if Figure 3 As shown in FIG. 1 , in the top screen G1, the first indicator group I1 is composed of a sand treatment indicator I11, a mold making indicator I12, a core indicator I13, a melting and pouring indicator I14, a cooling and conveying indicator I15, and a post-processing indicator I16. Among these indicators, the indicator corresponding to the selected process functions as a GUI element for causing the screen displayed on the display to transition from the top screen G1 to the second screen.

[0061] Specifically, if Figure 2 As shown, when the administrator selects the sand processing indicator I11 with the aid of the input device 27, the top-level screen G1 migrates to the sand processing screen (second screen) G11. When the administrator selects the molding indicator I12, the top-level screen G1 migrates to the molding screen (second screen) G12. When the administrator selects the core indicator I13, the top-level screen G1 migrates to the core screen (second screen) G13. When the administrator selects the melting and pouring indicator I14, the top-level screen G1 migrates to the melting and pouring screen (second screen) G14. When the administrator selects the cooling and conveying indicator I15, the top-level screen G1 migrates to the cooling and conveying screen (second screen) G15. When the administrator selects the post-processing indicator I16, the top-level screen G1 migrates to the post-processing screen (second screen) G16. Here, as Figure 4 and Figure 5As shown in FIG. 1 , the sand processing screen G11, the mold making screen G12, the core screen G13, the melting and pouring screen G14, and the cooling and conveying screen G15 show parameters for defining the status of each process. Figure 4 In the sand processing screen, the horizontal axis represents the number of sand boxes of the management object, and the vertical axis represents CB, moisture, sand temperature, and compression strength, respectively. It is a screen that displays parameters for defining the status of sand processing in time series.

[0062] In this way, the indicator corresponding to the selected process among the above-mentioned multiple indicators in the top screen G1 functions as a GUI element for causing the screen displayed on the display to migrate from the top screen G1 to the second screen that shows the status of the selected process in more detail. Therefore, compared with the structure in which the screen is displayed not by each process but by production-related information, safety-related information, and product quality information as described in Patent Document 1, the structure in which only the abnormal content of each process is displayed on the screen as described in Patent Document 2 and Patent Document 3, and the structure in which a table of the status of products obtained in each process of the manufacturing line 3 is displayed on the screen as described in Patent Document 4, the status of each process constituting the manufacturing line 3 can be appropriately presented to the manager. As a result, the status of each process constituting the manufacturing line 3 can be appropriately managed.

[0063] In addition, the composition Figure 3 At least one of the plurality of indicators in the first indicator group I1 of the top screen G1 shown in FIG. 1 may also be an indicator that hierarchically shows the status of the process corresponding to the indicator. Figure 3 In the example, the sand treatment condition is not at a normal level, so the sand treatment indicator I11 is displayed in a different color from other indicators. In this case, the sand treatment indicator I11 may be yellow when the sand treatment condition is at a caution level, and red when the sand treatment condition is at a warning level. Thus, the manager can understand the normality of the product in a graded manner.

[0064] In addition, if Figure 3 As shown, the top screen G1 may also include at least one of the threshold within rate display area A20 and the yield rate display area A21. The threshold within rate display area A20 displays the threshold within rate of the quality of the managed object processed or used in each process within the threshold range. The yield rate display area A21 displays the yield rate of the final product manufactured (the yield rate of the product). Therefore, according to the above structure, the status of each process can be managed more appropriately.

[0065] In addition, if Figure 3As shown, in the top-level screen G1, the first indicator group I1 can also be configured in a ring shape, for example, in a manner of surrounding the threshold rate display area A20. Thus, the information represented by the first indicator group I1 and the threshold rate display area (yield rate display area) A20 can be presented so that the manager can visually grasp it easily. In addition, the screen transition area group A1 can also be configured in a ring shape, for example, in a manner of surrounding the yield rate display area A21. Thus, the information represented by the screen transition area group A1 and the yield rate display area A21 can be presented so that the manager can visually grasp it easily.

[0066] (Third Display Process and Fourth Display Process)

[0067] The controller 22 of the management device 2 displays a third screen showing the defective ratio of each product type or each defective type on the display for the manufactured products (third display processing). In addition, the controller 22 of the management device 2 may also display a fourth screen showing the defective cause of each product on the display instead of the third screen for the manufactured products (fourth display processing).

[0068] like Figure 3 As shown, the top screen G1 includes a screen transition area group A1, which includes an analysis area (first area) A11, an inspection result input area A12, and a tracing area (second area) A13. The analysis area A11 functions as a GUI element for causing the screen displayed on the display to transition from the top screen G1 to the third screen. The tracing area A13 functions as a GUI element for causing the screen displayed on the display to transition from the top screen G1 to the fourth screen.

[0069] Specifically, if Figure 2 and Figure 3 As shown, when the manager selects the analysis area A11 by means of the input device 27, the top screen G1 migrates to the defective ratio screen (third screen) G17 classified by product. When the manager selects the inspection result input area A12, the top screen G1 migrates to the inspection result manual input screen G18. When the manager selects the traceability area A13, the top screen G1 migrates to the defective cause list screen (fourth screen) G19. In this way, the top screen G1 includes not only the first indicator group I1 indicating the status of each process, but also the screen transition area group A1, so that the manager can grasp the defective tendency of the manufactured products.

[0070] like Figure 6As shown, the defective ratio screen G17 by product shows the defective ratio of each product type for the manufactured products. Specifically, the pie chart A173 of the defective ratio screen G17 by product shows the defective ratio of each product type (for example, each product in the product names PRD234, PRD240, PRD21, PRD221, PRD129, PRD199, PRD125, PRD257, PRD276, PRD250, PRD805, PRD169, PRD312, PRD283, PRD249, PRD296, PRD5 and PRD259) among the defective products included in all the products manufactured in the last month. That is, the pie chart A173 shows the respective ratios obtained by dividing the number of defective products of each of the above product types (product names) included in the products manufactured in the last month by the number of defective products included in all the products manufactured in the last month. In addition, the product row A172 of the defective ratio screen G17 by product shows the product number, the number of products produced in the last month, the number of good products, the number of defective products, and the yield rate for each product type. For example, the product row A1722 shows the ratio of the number of good products 410 to the number of products produced 431 of the product name PRD240 manufactured in the last month as a yield rate of 95.13 (%). In addition, the defective ratio screen G17 by product includes a product area A170 and a defective area A171.

[0071] In addition, if Figure 2 and Figure 6 As shown, when the administrator selects the defective ratio section A171 of the defective ratio by product screen G17, the defective ratio by product screen G17 migrates (switches) to the product ratio by defective screen (third screen) G171. Similarly, when the administrator selects the product ratio section A170 of the product ratio by defective screen G171, the product ratio by defective screen G171 migrates (switches) to the defective ratio by product screen G17. Figure 7 As shown, the product ratio screen (third screen) G171 by defective classification shows the defect ratio of each defective type for the manufactured products. Specifically, the pie chart A174 of the product ratio screen G171 by defective classification shows the defect ratio of each defective type (for example, each defect among A defect, B defect, C defect, D defect, E defect, F defect, G defect, H defect, I defect and J defect) among the defective products contained in all the products manufactured in the last month. That is, the pie chart A174 and the row A175 of the defect cause show the respective ratios obtained by dividing the number of defective products of each defective type contained in the products manufactured in the last month by the number of defective products contained in all the products manufactured in the last month.

[0072] In the above example, the controller 22 of the management device 2 displays the defective ratio screen G17 classified by product or the product ratio screen G171 classified by defective as the third screen for the products manufactured in the last month. However, the present embodiment is not limited to this, and the third screen only needs to be about the manufactured products. Therefore, the manager can change the above one month to any period from the setting screen (not shown).

[0073] In addition, if Figure 2 As shown in FIG. 1 , when the manager selects A172 of the product on the defective ratio screen G17 classified by product, the defective ratio screen G17 classified by product moves to the defective cause screen G172. Figure 6 As shown in FIG. 1 , a row A172 of a product is displayed in the defect ratio screen G17 classified by product. The rows A1721 to A172n of products constituting the row A172 of the product function as GUI elements for transitioning to the defect cause screens G1721 to G172n corresponding to the rows A1721 to A172n of the product, respectively. For example, when the administrator selects Figure 6 In the case of the product row A1722 of the defective ratio screen G17 by product, the defective ratio screen G17 by product is displayed. Figure 8 The failure cause screen G1722 is moved.

[0074] like Figure 8 As shown, the defect cause screen G1722 shows a Pareto chart of defect causes of the corresponding product (here, product name PRD240) manufactured in the last month and the number of defects by cause for each month. This allows the manager to more appropriately grasp the defect tendency of the manufactured products.

[0075] like Fig. 9 As shown, the inspection result manual input screen G18 includes an identification ID area A182 that uniquely determines the product and an inspection result input area A183, and the manager can directly input various inspection results in these areas. As a result, the controller 22 of the management device 2 can appropriately display the third screen and the fourth screen on the display based on the inspection results. In addition, the inspection result manual input screen G18 includes a manual input area A180 and a CSV area A181.

[0076] like Figure 2 and Fig. 9As shown, when the administrator selects the CSV area A181 of the inspection result manual input screen G18, the inspection result manual input screen G18 migrates (switches) to the inspection result CSV screen G181. Similarly, when the administrator selects the manual input area A180 of the inspection result CSV screen G181, the inspection result CSV screen G181 migrates (switches) to the inspection result manual input screen G18. Fig. 9 As shown, the CSV area A181 includes a template area A184 and a load area A185. The administrator can download a template file by selecting the template area A184, and can read from a pre-listed CSV file by selecting the load area A185.

[0077] like Fig.10 As shown, the defect cause list screen G19 shows the defect cause of each product for the manufactured products. Specifically, the defect cause list screen G19 shows a defective product list for each product (here, each box of product name PRD240), including a product row A191 formed by product rows A1911 to A191n. Figure 2 As shown in FIG. 1 , when the manager selects the row A191 of the product on the defect cause list screen G19 , the defect cause list screen G19 is transferred to the tracing screen G191 . Fig.10 As shown, when the manager selects a row A191n of a product on the failure cause list screen G19, the failure cause list screen G19 transitions to a tracing screen G191n indicating production conditions of the product.

[0078] like Fig.11 As shown, the traceability screen G191n includes an identification ID area A1910, an inspection result area A1912, an information area A1913, an image area A1914, a management item list area A1915, and a management item graph area A1916a. Fig.11 In the identification ID area A1910, XXXXXXXXXXXX is displayed as the identification ID of the product, but the administrator can also directly enter it in the identification ID area. The inspection result area A1912 shows whether the product is good or defective. The information area A1913 shows various information such as the product's mold number, mold pattern, ladle number, material number, mold result, mold time, pouring time, furnace exit time, and sand falling time. For example, when a box collapse detection device (not shown) is introduced into the management system 1, the image area A1914 is as follows: Fig.11 The image is displayed as shown. The management item list area A1915 displays a list of management items. In addition, when the manager selects a row of a management item in the management item list area A1915, the management item graph area corresponding to the selected management item is displayed as a time series graph in the tracing screen G191n. For example, Fig.11 In the example, the row A19153 of the management item corresponding to the sand temperature in the management item list area A1915 is selected, and the management item graph area A1916a corresponding to the sand temperature is displayed in the traceability screen G191n. In addition, when the manager selects the row A19157 of the management item corresponding to the core setting load peak value in the management item list area A1915, as shown in FIG. Fig.12 As shown, a management item graph area A1916b corresponding to the core setting load peak value is displayed in the traceability screen G191n.

[0079] [Variation]

[0080] In the above example, the controller 22 of the management device 2 displays the top-level screen G1 including both the first indicator group I1 and the screen transition area group A1 on the display of the output device 28 in the first display process. However, in the present embodiment, it is not limited to this. The controller 22 of the management device 2 only needs to display the top-level screen G1 including the first indicator group I1, which is composed of indicators corresponding to the plurality of processes constituting the manufacturing line 3 and indicating the status of the process, as in the first indicator group I1, on the display of the output device 28 in the first display process. For example, the controller 22 of the management device 2 may also display the top-level screen G1 including only the first indicator group I1, or may display other indicator groups and area groups in addition to the first indicator group I1 and the screen transition area group A1 in the top-level screen G1.

[0081] In addition, in the above example, the first indicator group I1 is composed of the sand treatment indicator I11, the mold making indicator I12, the core indicator I13, the melting and pouring indicator I14, the cooling and conveying indicator I15, and the post-processing indicator I16. However, in the present embodiment, the structure of the first indicator group I1 is not particularly limited. For example, in the case where the manufacturing line 3 is formed by a sand treatment process, a mold making process, a core process, a pouring process, a cooling and conveying process, and other processes, the first indicator group I1 may also be configured to correspond to these processes. Specifically, the first indicator group I1 may also be composed of a pouring indicator (not shown) and other indicators (not shown) instead of the melting and pouring indicator I14 and the post-processing indicator I16. In addition, in this case, it is also possible that each device of the manufacturing line 3 is also composed of a pouring device (not shown) and other devices in a manner corresponding to each process instead of the melting and pouring device M4 and the post-processing device M6.

[0082] <Implementation Method 2>

[0083] In the first embodiment, in the first display process, a top screen G1 including a first indicator group I1 indicating the status of each process and a screen transition area group A1 is displayed on the display, and the screen transition area group A1 functions as a GUI element for migrating to a third screen indicating the defective ratio of each product type or each defective type or a fourth screen indicating the defective cause of each product. However, the present invention is not limited to this structure, and other structures may also be adopted. For example, the present invention may also adopt the following structure: in the first display process, a top screen G2 including a first indicator group I3 indicating the status of each process and a second indicator group I2 indicating the operating status of the manufacturing device used in each process is displayed on the display. Below, such an embodiment is described. In addition, for the sake of convenience of description, for components having the same functions as those described in the first embodiment, the same figure numbers are marked and their descriptions are omitted. In addition, each process included in the management method can be executed by the management system 1 in the same way as in the first embodiment, so the description of the management system 1 is also omitted.

[0084] 〔Management methods〕

[0085] The management method involved in this embodiment includes a first display process, a second display process, a third display process and a fourth display process. Figure 13 to Figure 17 The details of the management method of this embodiment will be described. Fig.13 This is a screen transition diagram showing the transition of the screen generated by the management device 2 involved in the second embodiment. Figure 14 to Figure 17 2 is a diagram showing an example of a screen generated by the management device 2 according to the second embodiment. Figure 2 As shown in FIG. 1 , the screen is migrated with the top screen G1 as the center. In this embodiment, Fig.13 As shown, the screen is migrated with the top screen G2 as the center.

[0086] (First Display Process and Second Display Process)

[0087] like Fig.14 As shown, the controller 22 of the management device 2 displays a top-level screen (first screen) G2 including a first indicator group I3 and a second indicator group I2 on the display of the output device 28. The first indicator group I3 is composed of indicators corresponding to each of the multiple processes constituting the manufacturing line 3 and indicating the status of the corresponding process. The second indicator group I2 is composed of indicators corresponding to each of the multiple processes constituting the manufacturing line 3 and indicating the operating status of the manufacturing device used in the corresponding process. That is, the first indicator group I3 is an indicator group corresponding to the first indicator group I1 in Implementation Example 1.

[0088] In addition, the controller 22 of the management device 2 displays a more detailed display of the Fig.14 A second screen (for example, Fig.15 That is, the controller 22 of the management device 2 displays the Fig.14 The first indicator group I3 shown on the left side of is operated to migrate from the top-level screen G2 to the second screen.

[0089] Here, if Fig.14 As shown, in the top screen G2, the first indicator group I3 is composed of a sand treatment quality indicator I25, a molding quality indicator I26, a pouring and cooling quality indicator I27, and a post-processing quality indicator I28. The indicator corresponding to the selected process among the sand treatment quality indicator I25, the molding quality indicator I26, the pouring and cooling quality indicator I27, and the post-processing quality indicator I28 functions as a GUI element for causing the screen displayed on the display to transition from the top screen G2 to the second screen showing the status of the process in more detail.

[0090] Specifically, if Fig.13 As shown, when the administrator selects the sand treatment quality indicator I25 by means of the input device 27, the top screen G2 migrates to the sand treatment quality monitoring screen (second screen) G25. When the administrator selects the molding quality indicator I26, the top screen G2 migrates to the molding quality monitoring screen (second screen) G26 (not shown). When the administrator selects the pouring and cooling quality indicator I27, the top screen G2 migrates to the pouring and cooling quality monitoring screen (second screen) G27 (not shown). When the administrator selects the post-processing quality indicator I28, the top screen G2 migrates to the post-processing quality monitoring screen (second screen) G28 (not shown).

[0091] In this way, the indicators corresponding to the selected process among the sand treatment quality indicator I25, the molding quality indicator I26, the pouring cooling quality indicator I27, and the post-processing quality indicator I28 in the top screen G2 function as GUI elements for migrating the screen displayed on the display from the top screen G2 to the second screen showing the status of the process in more detail. In this way, the status of each process constituting the manufacturing line 3 can be appropriately presented to the manager.

[0092] In addition, if Fig.14As shown, the top screen G2 may also include at least one of a yield rate display area A23 and a molding sand box number display area (number display area) A22. The yield rate display area A23 displays the yield rate (product yield rate) of the final product manufactured within a predetermined period (here, 24 hours). The molding sand box number display area (number display area) A22 displays the number of final products manufactured within a predetermined period. In this way, the state of the manufacturing line can be managed more appropriately.

[0093] In addition, if Fig.14 As shown, in the top screen G2, the first indicator group I3 may also be configured in a ring shape in a manner of surrounding the yield rate display area A23. Thus, the information represented by the first indicator group I3 and the yield rate display area A23 can be presented to the manager more appropriately. In addition, in the top screen G2, the second indicator group I2 may also be configured in a ring shape in a manner of surrounding the molding sand box number display area A22. Thus, the information represented by the second indicator group I2 and the molding sand box number display area A22 can be presented to the manager more appropriately.

[0094] In addition, if Fig.14 As shown, the top screen G2 may also include at least one of a stop time display area A25 for displaying the total time that the equipment corresponding to each process is stopped in 24 hours, and a unit time molding number display area A24 for displaying the number of moldings per unit time. Thus, the state of the manufacturing line 3 can be properly managed. In addition, the number of moldings per unit time refers to the number of moldings of products per unit operation time (for example, 8 hours) that the equipment corresponding to each process continues to operate.

[0095] (Third Display Process)

[0096] The controller 22 of the management device 2 displays in the display a more detailed view of the Fig.14 A third screen (for example, Fig.17 That is, the controller 22 of the management device 2 displays the Fig.14 The second indicator group I2 shown on the right side of is operated to migrate from the top-level screen G2 to the third screen.

[0097] like Fig.14 As shown, in the top-level screen G2, the indicators corresponding to the selected process among the sand processing operation indicator I21, the molding operation indicator I22, the pouring cooling operation indicator I23 and the post-processing operation indicator I24 constituting the second indicator group I2 function as GUI elements for migrating the screen displayed in the display from the top-level screen G2 to the third screen.

[0098] Specifically, if Fig.13 and Fig.14 As shown, when the administrator selects the sand processing operation indicator I21 by means of the input device 27, the top screen G2 migrates to the sand processing operation monitoring screen (third screen) G21. When the administrator selects the mold making operation indicator I22, the top screen G2 migrates to the mold making operation monitoring screen (third screen) G22 (not shown). When the administrator selects the pouring and cooling operation indicator I23, the top screen G2 migrates to the pouring and cooling operation monitoring screen (third screen) G23 (not shown). When the administrator selects the post-processing operation indicator I24, the top screen G2 migrates to the post-processing operation monitoring screen (third screen) G24 (not shown).

[0099] The sand processing operation monitoring screen G21, the mold making operation monitoring screen G22, the pouring and cooling operation monitoring screen G23, and the post-processing operation monitoring screen G24 respectively display the operation status of the manufacturing device in the equipment of the corresponding process and the abnormal history of the manufacturing device. The operation status of the manufacturing device refers to whether the manufacturing device is in a normal state or an abnormal state. The abnormal state of the manufacturing device, for example, refers to the motor of the manufacturing device being overloaded, or the temperature rising, or the cycle time of the process and the management value of the control factors (temperature, pressure, and air volume of the dust collector, etc.) exceeding the limit. For example, Fig.17 As shown, the sand processing operation monitoring screen G21 shows whether the manufacturing device MIA, sand processing line, MIE and dust collector in the sand processing equipment M1 are in a normal or abnormal stop state through the rows A2111 to S2114 of the manufacturing devices. Thus, for example, when the sand processing operation indicator I21 in the second indicator group I2 is displaying a warning or a caution, the manager can understand which manufacturing device in the sand processing equipment M1 caused the sand processing operation indicator I21 to display a warning or a caution. In addition, Fig.17 In the sand processing operation monitoring screen G21, the history record A212 of the abnormal details of the manufacturing device in the abnormal stop state is displayed. Thereby, the manager can appropriately grasp the operating state of the manufacturing device in the sand processing facility M1.

[0100] In this way, by including the second indicator group I2 in the top-level screen G2, the manager can understand the operating status of the manufacturing equipment used in each process constituting the manufacturing line 3.

[0101] In addition, the composition Fig.14 At least one of the plurality of indicators in the second indicator group I2 of the top screen G2 shown in FIG. 1 may be an indicator that hierarchically shows the normality of the manufacturing device used in the process corresponding to the indicator. Fig.14In the example, the operating status of the manufacturing device used in the sand processing is abnormal, so the sand processing operation indicator I21 is displayed in a different color from other indicators. In this case, the sand processing operation indicator I21 may be yellow when the sand processing status is at a caution level, and may be red when the sand processing status is at a warning level. Thus, the manager can grasp the normality of the manufacturing devices used in each process constituting the manufacturing line 3 in a hierarchical manner.

[0102] (Fourth display process)

[0103] The controller 22 of the management device 2 displays a fourth screen (eg, Fig.16 ), the fourth picture is the same as the second picture (for example, Fig.15 ) is displayed on the display, and the status of the process performed in the manufacturing device is displayed in time series (fourth display processing). That is, the controller 22 of the management device 2 displays the fourth screen on the display, which is transferred from the second screen by selecting the manufacturing device in the second screen and shows the process performed in the manufacturing device in the second screen in more detail.

[0104] Here, if Fig.13 As shown, the sand processing quality monitoring screen G25 as the second screen includes a sand processing equipment quality area group (status display area group) A251, which is an equipment quality display area (status display area) corresponding to each of the multiple manufacturing devices used in the sand processing (selected process), and displays the status of the process implemented in the corresponding manufacturing device. The molding quality monitoring screen G26 includes a molding equipment quality area group A261, which is an equipment quality display area corresponding to each of the multiple manufacturing devices used in the molding, and displays the status of the process implemented in the corresponding manufacturing device. The pouring cooling quality monitoring screen G27 includes a pouring cooling equipment quality area group A271, which is an equipment quality display area corresponding to each of the multiple manufacturing devices used in the pouring cooling, and displays the status of the process implemented in the corresponding manufacturing device. The post-processing quality monitoring screen G28 includes a post-processing equipment quality area group A281 which is an equipment quality display area corresponding to each of a plurality of manufacturing apparatuses used in post-processing and displays the status of the process performed in the corresponding manufacturing apparatus.

[0105] In addition, if Fig.13As shown, in the sand processing quality monitoring screen (second screen) G25, the molding quality monitoring screen (second screen) G26, the pouring and cooling quality monitoring screen (second screen) G27 and the post-processing quality monitoring screen (second screen) G28, the equipment quality area (status display area) corresponding to the selected equipment in the equipment quality area constituting the sand processing equipment quality area group A251, the molding equipment quality area group A261, the pouring and cooling equipment quality area group A271 and the post-processing equipment quality area group A281 functions as a GUI element for migrating the screen displayed on the display from the second screen to the fourth screen.

[0106] Specifically, if Fig.13 As shown, when the administrator selects any one of the sand processing equipment quality areas of the sand processing equipment quality area group (status display area group) A251 constituting the sand processing quality monitoring screen G25, the sand processing quality monitoring screen G25 is transferred from the sand processing equipment quality area corresponding to the selected equipment to the sand processing equipment quality monitoring screen G251 (any one of the sand processing equipment quality monitoring screens G2511 to G251n). When the administrator selects any one of the molding equipment quality areas of the molding equipment quality area group (status display area group) A261 constituting the molding quality monitoring screen G26, the molding quality monitoring screen G26 is transferred from the molding equipment quality area corresponding to the selected equipment to the molding equipment quality monitoring screen G261 (any one of the molding equipment quality monitoring screens G2611 to G261n). When the administrator selects any one of the pouring cooling equipment quality areas of the pouring cooling equipment quality area group (status display area group) A271 constituting the pouring cooling quality monitoring screen G27, the pouring cooling quality monitoring screen G27 migrates from the pouring cooling equipment quality area corresponding to the selected equipment to the pouring cooling equipment quality monitoring screen G271 (any one of the pouring cooling equipment quality monitoring screens G2711 to G271n). When the administrator selects any one of the post-processing equipment quality areas of the post-processing equipment quality area group (status display area group) A281 constituting the post-processing quality monitoring screen G28, the post-processing quality monitoring screen G28 migrates from the post-processing equipment quality area corresponding to the selected equipment to the post-processing equipment quality monitoring screen G281 (any one of the post-processing equipment quality monitoring screens G2811 to G281n).

[0107] More specifically, if Fig.15As shown, the sand processing quality monitoring screen G25 includes a sand processing equipment quality area group (status display area group) A251, which is composed of an MIA area (status display area) A2511, an RCT area (status display area) A2512, a BIN area (status display area) A2513, a BMIC area (status display area) A2514, an MS area (status display area) A2515, a MIE area (status display area) A2516, a HOPPER area (status display area) A2517, and an IDST area (status display area) A2518 for displaying the status of the processes implemented in the manufacturing devices (MIA, RCT, BIN, BMIC, MS, MIE, HOPPER, and IDST) used in the corresponding processes. In addition, in the sand processing quality monitoring screen G25, when the administrator selects the MIA in the status display area constituting the sand processing equipment quality area group A251, the sand processing quality monitoring screen G25 is transferred from the MIA area A2511 corresponding to the MIA as the selected equipment to the sand processing equipment quality monitoring screen G2511. Fig.16 As shown, the sand processing equipment quality monitoring screen G2511 is a screen in which the horizontal axis represents the collection time of the management object, and the vertical axis represents the moisture content, sand temperature, and actual flow rate of the management object processed or used in MIA, and is a screen that shows the status of the process implemented in the manufacturing device used for sand processing in a time series. Thus, the manager can grasp the status of the process implemented in the manufacturing device in a time series.

[0108] Furthermore, at least one of the equipment quality areas (status display areas) constituting the equipment quality area group (status display area group) in the second screen may also function as an indicator showing the status of the process performed in the manufacturing device corresponding to the equipment quality area. Fig.15 In the sand processing quality monitoring screen G25, the MIA area A2511 of the sand processing equipment quality area group A251 constituting the sand processing quality monitoring screen G25 displays a warning by displaying a word "warning" when the status of the process implemented in the MIA used in the sand processing is at a warning level. This allows the manager to more appropriately grasp the status of the process implemented in the manufacturing device corresponding to each process constituting the manufacturing line 3.

[0109] in addition, Fig.15 The sand processing quality monitoring screen G25 can also display an alarm history record A252, which is a history record of any of the status display areas constituting the sand processing equipment quality area group A251 that has displayed a warning. In this way, the manager can grasp the status of the process implemented in the manufacturing device corresponding to each process constituting the manufacturing line 3 in a time series.

[0110] [Variation]

[0111] In the above example, the controller 22 of the management device 2 displays the top screen (first screen) G2 including the first indicator group I3 and the second indicator group I2 on the display of the output device 28, but it is not limited to this in the present embodiment. In the present embodiment, the controller 22 of the management device 2 may also display the first indicator group I1 in the embodiment 1 on the display of the output device 28 instead of the first indicator group I3. In addition, in this case, the controller 22 of the management device 2 may also arrange the second indicator group I2 at the position of the first indicator group I3 and arrange the first indicator group I1 at the position of the second indicator group I2 in a manner that is the same as the configuration in the embodiment 1. That is, the controller 22 of the management device 2 can arbitrarily set the left and right configurations of each indicator group and block group.

[0112] 〔Software-based implementation example〕

[0113] The management device 2 in the management system 1 and the control module of the manufacturing line 3 (especially the controller 22 and P1 to P6) can be implemented by a logic circuit (hardware) formed on an integrated circuit (IC chip) or the like, or by software.

[0114] In the latter case, the management device 2 and the manufacturing line 3 are provided with a computer that executes commands of a program that is software for realizing each function. The computer, for example, has one or more processors and a computer-readable recording medium storing the above-mentioned program. Moreover, in the above-mentioned computer, the purpose of the present invention is achieved by the above-mentioned processor reading and executing the above-mentioned program from the above-mentioned recording medium. As the above-mentioned processor, for example, a CPU (Central Processing Unit) can be used. As the above-mentioned recording medium, in addition to being able to use "non-transient tangible media", such as ROM (Read Only Memory), etc., magnetic tapes, optical disks, cards, semiconductor memories, programmable logic circuits, etc. can also be used. In addition, it is also possible to have a RAM (Random Access Memory) for expanding the above-mentioned program. In addition, the above-mentioned program can also be supplied to the above-mentioned computer via any transmission medium (communication network, broadcast wave, etc.) that can transmit the program. In addition, one embodiment of the present invention can also be implemented in the form of a data signal embedded in a carrier wave that specifically implements the above-mentioned program through electronic transmission.

[0115] The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present invention.

[0116] 〔Summarize〕

[0117] The management method involved in this embodiment is a management method for managing a manufacturing line formed by multiple processes. The management method includes the following processing: a first display processing, in which a first screen representing the status of each process is displayed on a display by a first indicator group formed by indicators corresponding to each process; and a second display processing, in which a second screen representing the status of a specific process in more detail is displayed on the display. The indicator corresponding to the specific process in the first indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the second screen.

[0118] According to the above configuration, the indicator corresponding to the specific process in the first indicator group in the first screen functions as a GUI element for causing the screen displayed on the display to transition from the first screen to the second screen showing the status of the specific process in more detail.

[0119] Thus, compared with the structure in which the screen displays production-related information, safety-related information, and product quality information instead of each process as in the technology described in Patent Document 1, the structure in which only the abnormal contents of each process are displayed on the screen as in the technologies described in Patent Documents 2 and 3, and the structure in which a table of the status of products obtained in each process of the manufacturing line is displayed on the screen as in the technology described in Patent Document 4, the status of each process constituting the manufacturing line can be appropriately presented to the manager. As a result, the status of each process constituting the manufacturing line can be appropriately managed.

[0120] In the management method according to the present embodiment, preferably, the first indicator group includes at least one indicator that shows the status of the corresponding process in a hierarchical manner.

[0121] According to the above configuration, at least one indicator shows the status of the process corresponding to the indicator in a hierarchical manner, so that the manager can understand the status in a hierarchical manner.

[0122] In the management method according to the present embodiment, it is preferred that a third display process is further included, in which a third screen showing the defective ratio of each product type or each defective type is displayed on the display for the manufactured products. In addition, it is preferred that the first screen further includes a first area, and the first area functions as a GUI element for causing the screen displayed on the display to transition from the first screen to the third screen.

[0123] According to the above configuration, the first area in the first screen functions as a GUI element for causing the screen displayed on the display to transition from the first screen to a third screen showing the defective ratio for each product type or each defective type for manufactured products. Thus, the manager can understand the status of manufactured products.

[0124] In the management method according to the present embodiment, it is preferred that a fourth display process is further included, in which a fourth screen showing the defective cause of each product is displayed on the display for the manufactured products. In addition, it is preferred that the first screen further includes a second area, and the second area functions as a GUI element for causing the screen displayed on the display to transition from the first screen to the fourth screen.

[0125] According to the above configuration, the second area in the first screen functions as a GUI element for causing the screen displayed on the display to transition from the first screen to the fourth screen showing the cause of failure for each manufactured product.

[0126] This allows the manager to understand the status of manufactured products.

[0127] The management method involved in this embodiment is a management method for managing a manufacturing line formed by multiple processes. The management method includes the following processing: a first display processing, in which a first screen is displayed on a display, which indicates the status of each process through a first indicator group composed of indicators corresponding to each process, and the operating status of the manufacturing device used in each process is displayed through a second indicator group composed of indicators corresponding to each process; a second display processing, in which a second screen is displayed on the display, which indicates the status of a specific process in more detail; and a third display processing, in which a third screen is displayed on the display, which indicates the operating status of the manufacturing device used in a specific process in more detail. The indicator corresponding to the specific process in the first indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the second screen. The indicator corresponding to the specific process in the second indicator group functions as a GUI element for migrating the screen displayed on the display from the first screen to the third screen.

[0128] According to the above structure, the indicator of the first screen functions as a GUI for migrating the screen displayed on the display from the first screen to the second screen, or from the first screen to the third screen. Thus, the manager can grasp the status of each process constituting the manufacturing line or the status of the manufacturing equipment used in each process.

[0129] In addition, the process whose detailed status is displayed in the second display processing (recorded as a "specific process") and the process whose detailed status is displayed in the third display processing (recorded as a "specific process") may be the same process or different processes.

[0130] In the management method according to the present embodiment, preferably, the first indicator group includes at least one indicator that shows the status of the corresponding process in a hierarchical manner.

[0131] According to the above configuration, at least one indicator shows the status of the process corresponding to the indicator in a hierarchical manner. Thus, the manager can understand the status of each process constituting the manufacturing line in a hierarchical manner.

[0132] In the management method according to the present embodiment, preferably, the second indicator group includes at least one indicator that hierarchically indicates an operating state of a manufacturing device used in a corresponding process.

[0133] According to the above configuration, at least one indicator hierarchically shows the operating status of the manufacturing device used in the process corresponding to the indicator. Thus, the manager can hierarchically understand the operating status of the manufacturing device used in each process constituting the manufacturing line.

[0134] In the management method according to the present embodiment, preferably, in the first screen, the first indicator group is arranged in a ring shape.

[0135] According to the above configuration, the first indicator group can be presented so as to be easily visually understood by the manager.

[0136] The management device according to the present embodiment manages a manufacturing line formed of a plurality of processes, and includes a controller that executes each process included in the management method.

[0137] According to the above-mentioned structure, the same effect as the above-mentioned management method is achieved.

[0138] In the management device according to the present embodiment, the controller may include a processor and a memory, and the processor may execute each process included in the management method according to a program stored in the memory.

[0139] According to the above-mentioned structure, the same effect as the above-mentioned management method is achieved.

[0140] In addition, the management method of this embodiment can be applied to a casting manufacturing line, for example. In this case, the processes constituting the manufacturing line include, for example, a sand treatment process, a mold making process, a core process, a melting and pouring process, a cooling and conveying process, and a post-processing process.

[0141] The sand treatment process in the casting manufacturing line is a process in which the impurities mixed in the regenerated sand are separated and removed, the temperature and moisture content of the regenerated sand are measured, and water in an amount proportional to the measured values ​​is added to the regenerated sand, and then an additive such as bentonite and water are added to the regenerated sand and stirred to mix the regenerated sand to produce mixed sand. In the sand treatment process, for example, CB, moisture, sand temperature, air permeability, and compressive strength are managed as parameters for defining the status of the sand treatment process.

[0142] Therefore, for example, in the first screen, the indicator corresponding to the sand treatment process shows the general status of the sand treatment process determined based on these parameters. As an example, the general status of the sand treatment process is represented by three levels of normal (e.g., cyan), caution (e.g., yellow), and abnormal (e.g., red) by color. If the above-mentioned parameters in the sand treatment process are all within the normal range, the indicator is cyan. On the other hand, even if one of the above-mentioned parameters exceeds the normal range and reaches the caution level, the indicator turns yellow to call the attention of the manager. Furthermore, even if one of the above-mentioned parameters reaches the dangerous level, the indicator turns red to warn the manager. In this case, the indicator prompts the manager to maintain the manufacturing line and, if necessary, prompts the manager to stop the manufacturing line.

[0143] When any indicator in the first screen shows a call for attention / warning, the manager needs to confirm more detailed information, such as which part of the process has what kind of manufacturing problem. Therefore, the indicator in the first screen functions as a GUI element for migrating the display from the above-mentioned first screen to the above-mentioned second screen. For example, when the indicator of the sand processing in the first screen turns yellow or red, the manager migrates from the first screen to the second screen by operating the indicator. In the second screen corresponding to the sand processing, the values ​​of the parameters in the sand processing (CB, moisture, sand temperature, and compression strength, etc.) are separately shown. By confirming the detailed status of each parameter in the second screen, the manager can confirm through the second screen what part of the abnormality of the indicator displayed in the first screen occurs. As a result, the manager can accurately detect and respond to the occurrence of defective products and abnormalities in the manufacturing line as early as possible.

[0144] The molding process is a process of putting the mixed sand obtained in the sand treatment process into a mold box and fixing the sand to make a casting mold.
