[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-094503 Summary of the Invention [Problem to be solved by the invention]

[0005] In the molding management system described in Patent Document 1, information indicating the quality history of a molded product is stored, such as information indicating the pressure, temperature, and force for each shot in the injection molding device that molds the molded product. In other words, the molding management system does not store information indicating the quality inspection history of the molded product. Furthermore, in the molding management system, information indicating the operating status of the injection molding device and the history of setting changes to the injection molding device, as well as information indicating the quality history of the molded product, is also information indicating the history of the injection molding device. For this reason, the molding management system insufficiently displays information indicating the history of the molded product. This means that the traceability of the molded product is insufficient, which is undesirable. [Means for solving the problem]

[0009] <Embodiment> Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0010] <Outline of molding management system> First, an overview of the molding management system according to the embodiment will be described.

[0011] A molding management system according to an embodiment manages the production of products in a production process that includes an injection molding process of the products using an injection molding device. The molding management system includes a server. The server is communicably connected to a terminal device. The server also includes a memory unit and a control unit. The memory unit stores one or more pieces of lot information in which lot identification information that identifies the lot of the products is associated with lot-related information that includes at least history information as one or more pieces of information related to the lot of the products. Here, the history information refers to information that indicates the history of the products produced by the lot. The control unit causes the terminal device to display a history information display image that displays history information included in the lot-related information of lot information that indicates a target lot selected from the lots indicated by each of the one or more pieces of lot information stored in the memory unit.

[0012] As a result, the molding management system according to the embodiment can improve the traceability of molded products.

[0013] The configuration of the molding management system according to the embodiment and the processing performed by the server included in the molding management system will be described in detail below.

[0014] Furthermore, if the traceability of a product is insufficient, it may not be possible to accurately determine whether the product is good or bad when a quality problem occurs, and many lots, including products that may be good, may end up being discarded or put on hold. To prevent this when traceability is insufficient, it is necessary to perform a full reinspection. However, full reinspection is time-consuming and costly, and is not desirable. For this reason, it is useful to be able to improve the traceability of molded products, as with the molding management system of the embodiment.

[0015] <Configuration of molding management system> The configuration of the molding management system according to the embodiment will be described below by taking the molding management system 1 as an example.

[0016] FIG. 1 is a diagram showing an example of the configuration of a molding management system 1. As shown in FIG.

[0017] The molding management system 1 is a type of manufacturing execution system (MES). For example, the molding management system 1 includes one or more managed devices 10, an information processing device 20, and a server 30. The molding management system 1 may be configured not to include some or all of the one or more managed devices 10. The molding management system 1 may also be configured not to include the information processing device 20. In the following, as an example, a case will be described in which the molding management system 1 includes a plurality of managed devices 10 as the one or more managed devices 10.

[0018] Each of the multiple managed devices 10 included in the molding management system 1 is a device managed by the molding management system 1. In FIG. 1, for convenience of explanation, the multiple managed devices 10 are each denoted by the same reference numeral. However, some or all of the multiple managed devices 10 may be different types of devices. The multiple managed devices 10 include at least one injection molding device that performs injection molding of a product using a resin such as plastic. The injection molding device 11 shown in FIG. 1 is an example of such an injection molding device. Note that the multiple managed devices 10 may also include an injection molding device that performs metal injection molding (MIM) of a product. In the following, for convenience of explanation, injection molding of a product using a resin such as plastic will be simply referred to as injection molding. In the following, an injection molding device that performs injection molding of a product using a resin such as plastic will be simply referred to as an injection molding device. Furthermore, the multiple managed devices 10 include, in addition to the injection molding device, for example, peripheral equipment of the injection molding device. Examples of peripheral equipment of the injection molding device include, but are not limited to, a material supply device that supplies the injection molding device with material used by the injection molding device to inject mold the product, a transport device that transports the product injection molded by the injection molding device, a cleaning device that cleans the product injection molded by the injection molding device, and a sintering device that sinters the product after being cleaned by the cleaning device. Furthermore, at least one injection molding device included in the multiple managed devices 10 may be a device that performs injection molding using a material other than resin and metal.

[0019] The molding management system 1 manages the production of products in a production process that includes an injection molding process of the products using injection molding devices included in the multiple managed devices 10. Here, the injection molding devices included in the multiple managed devices 10 may have any configuration as long as they are capable of producing products by injection molding. For convenience of explanation, one injection molding of a product using the injection molding device will be referred to as one shot in the following description. In this case, for example, two shots refer to two injection moldings of a product using the injection molding device. Also, for convenience of explanation, each of one or more cavities in a mold that are filled with resin during one shot of molding a product will be referred to as a cavity in the following description. For example, an injection molding device equipped with a mold having two such cavities will mold two products in one shot.

[0020] The information processing device 20 acquires status information indicating the status of each of the multiple managed devices 10 from the managed device 10. For example, the information processing device 20 acquires status information about the injection molding device 11 from the injection molding device 11. Such status information includes a timestamp indicating the date and time when the status information was acquired by the information processing device 20. Some status information also includes device identification information that identifies the managed device 10 in the state indicated by the status information. The status information also includes detection information detected by one or more sensors attached to the managed device 10. The detection information includes, for example, information indicating temperature, information indicating pressure, information indicating current value, information indicating voltage value, etc. That is, the one or more sensors include, but are not limited to, a thermometer, a pressure gauge, an ammeter, a voltmeter, etc. Note that the detection information may include other information detected by the sensors instead of some or all of the above information, or in addition to all of the above information. The status information also includes operating status information indicating the operating status of the managed device 10. The operating status information indicating the operating status of the managed device 10 may be any information as long as it includes information indicating whether the managed device 10 is operating. Furthermore, the information processing device 20 may acquire such status information periodically or non-periodically. As an example, the following describes a case where the information processing device 20 acquires status information each time the above-mentioned one shot is taken. When the information processing device 20 acquires certain status information, it outputs the acquired status information to the server 30. This allows the information processing device 20 to store the acquired status information in the server 30.

[0021] The information processing device 20 is, for example, a workstation, a desktop PC (Personal Computer), a notebook PC, etc., but is not limited to these. The information processing device 20 is communicably connected to each of the multiple managed devices 10 via wired or wireless communication. The communication network connecting the information processing device 20 and each of the multiple managed devices 10 is, for example, a local area network (LAN) within a facility where the multiple managed devices 10 are installed, but is not limited to this. The communication network may also be another communication network such as the Internet or a mobile communication network.

[0022] The server 30 stores the status information acquired by the information processing device 20. For example, when the server 30 acquires certain status information from the information processing device 20, it stores the acquired status information. Here, if the server 30 has already stored status information including device identification information included in the status information, it replaces the already stored status information with the newly acquired status information. This allows the server 30 to always keep the status information indicating the status of the managed device 10 indicated by the device identification information up to date. Note that the server 30 may be configured to store all acquired status information without performing such replacement. Furthermore, even if the server 30 performs such replacement, it may be configured to newly store the status information before the replacement as history information indicating the status history of the managed device 10.

[0023] In addition, in response to a request from a terminal device communicatively connected to the server 30, the server 30 displays various images based on status information stored in the server 30 on the display unit of the terminal device. Here, the images refer to GUIs (Graphical User Interfaces), icons, windows on an OS (Operating System), and the like. Hereinafter, as an example, a case will be described in which the server 30 is communicatively connected to the terminal device 40 as shown in FIG. 1 . Note that in this embodiment, the process of logging in to the server 30 by the terminal device 40 is known, and therefore will not be described here. For ease of explanation, the server 30 receiving an operation from the terminal device 40 via an image displayed on the terminal device 40 will be simply referred to as the server 30 receiving an operation. In other words, in the following, the server 30 performing a certain process in response to a received operation means that the server 30 performs the process in response to the operation received from the terminal device 40 via an image displayed on the terminal device 40.

[0024] The server 30 also accepts various types of information in response to the received operation. For example, the server 30 stores master data including various types of information about products produced by the injection molding apparatus 11 in response to the received operation. The master data includes, for example, product identification information that identifies the various products produced by the injection molding apparatus 11, product type information that indicates the type of product identified by each product identification information, planned production quantity information that indicates the planned production quantity of the product identified by each product identification information, and mold identification information that identifies the mold used to produce the product identified by each product identification information. The master data may have any data structure. For example, the various types of information included in the master data are included in the master data as information associated with the product identification information. Note that the various types of information included in the master data may be information associated with product type information instead of information associated with the product identification information, information associated with both the product identification information and the product type information, or information associated with other information.

[0025] Furthermore, in response to the received operation, the server 30 displays a lot search image on the display unit of the terminal device 40, which accepts a lot search operation for searching for a product lot. The display unit may be, for example, a display of the terminal device 40 or a display device communicably connected to the terminal device 40, but is not limited to these. In the following, as an example, a case will be described in which the display unit is the display of the terminal device 40. Also, in the following, for convenience of explanation, displaying an image on the display unit will be referred to as "displaying the image." The lot search image is an image that accepts various pieces of information that can be used as a search key through the aforementioned lot search operation. In the following, for convenience of explanation, a product lot will be simply referred to as a lot. A lot is a group of one or more products to which lot identification information is assigned for management purposes. Therefore, in the following, for convenience of explanation, products to which lot identification information identifying a certain lot is assigned will be referred to as products of that lot. The lot identification information may be any information that can identify the lot, for example, an ID (Identifier) ​​that identifies the lot, a character string that identifies the lot, or other information that can identify the lot.

[0026] Here, the server 30 stores lot identification information and lot-related information including one or more pieces of information related to the lot, in association with each other. As a result, when searching for information on a certain lot of products, the server 30 can use not only the lot identification information that identifies the lot, but also each of the one or more pieces of information included in the lot-related information associated with the lot identification information as search keys for the lot. In other words, in the lot search image, in addition to the lot identification information, each of the one or more pieces of information included in the lot-related information can be used as search keys for searching for the lot. Hereinafter, for convenience of explanation, information in which lot identification information that identifies a certain lot and lot-related information including one or more pieces of information related to the lot are associated with each other will be referred to as lot information indicating the lot. In other words, when the server 30 receives at least one piece of information from the one or more pieces of information included in the lot-related information through a lot search operation via the lot search image, it displays lot information indicating the lot identified by each of the one or more pieces of lot identification information associated with the received at least one piece of information. This allows the server 30 to easily search for information on products in a desired lot. For this reason, the server 30 stores one or more pieces of lot information for each piece of lot identification information. Here, the lot information is, for example, information that is generated or updated based on information received from a user via one of the update functions that can be executed by the server 30, and is information that is stored in the server 30. Certain lot information includes, for example, lot identification information that identifies the lot indicated by the lot information, and lot-related information about the lot.More specifically, the lot-related information includes: number of products in the lot; type of products in the lot; process information indicating the process currently being performed on the products in the lot; lot status information indicating the status of the lot; start date and time information indicating the date and time when production of the products in the lot began; quality information indicating the results of quality inspections performed on the products in the lot; injection molding device information regarding the injection molding device used to mold the products in the lot; mold identification information identifying the mold installed in the injection molding device; cavity number information indicating the number of cavities in the mold; and history information regarding the products in the lot. The lot-related information may include other information related to the lot instead of, or in addition to, some or all of the above information. However, the following describes, as an example, a case in which at least the history information is included in the lot information. Furthermore, if a quality inspection has not been performed on the product, the quality information indicates that the quality inspection has not been performed on the product. The injection molding apparatus-related information is information including, for example, injection molding apparatus identification information that identifies the injection molding apparatus, operating status information that indicates the operating status of the injection molding apparatus, detection information about the injection molding apparatus, etc. The history information is information including lot information change history information that indicates the history of changes to the lot information, material history information that indicates the history of the use of materials for the products of the lot, work process change history information that indicates the history of changes to the work process performed on the products of the lot, lot management history information that indicates the history of management of the lot, quality inspection history information that indicates the history of quality inspection of the products of the lot, etc. Note that the history information may be configured to include other information about the products of the lot instead of some or all of the above information, or in addition to all of the above information.

[0027] The method for associating various pieces of information included in the lot-related information with the lot identification information and storing them as lot information in the server 30 may be a known method, such as a method via a GUI, or may be a method to be developed in the future. For the sake of simplicity, the following description will be given, as an example, of a case in which one or more pieces of lot information are pre-stored in the server 30. This means that the aforementioned history information is pre-stored in the server 30.

[0028] For ease of explanation, a group of one or more materials to which material lot identification information is assigned for management reasons will be referred to as a material lot. In other words, material lot identification information is information that identifies a material lot. For ease of explanation, a material to which material lot identification information that identifies a certain material lot is assigned will be referred to as the material of that material lot. Note that material lot identification information is generally assigned by the material manufacturer. However, material lot identification information is not limited to this and may be other information that can identify a material lot.

[0029] In response to the received operation, the server 30 displays a history information display image that displays history information included in the lot-related information of the lot information indicating the target lot selected from one or more lot information stored in the server 30.

[0030] For example, the server 30 displays the history information display image by accepting an operation via a main menu image P1 as shown in Fig. 2. Fig. 2 is a diagram showing an example of the main menu image P1.

[0031] When a predetermined main menu image display operation is received, the server 30 displays the main menu image P1. In the example shown in Fig. 2, the main menu image P1 includes six buttons, namely, button B11 to button B16.

[0032] The button B11 is a button that displays a dashboard image. When the server 30 receives a selection operation on the button B11, the server 30 generates a dashboard image and displays the generated dashboard image. Here, the dashboard image is an image that displays information necessary for a user of the terminal device 40 to manage the production of products by the injection molding device designated by the user while the injection molding device is in operation. In this embodiment, the selection operation is a click, a tap, or the like, but is not limited to these.

[0033] Button B12 is a button that displays a master data management image. When the server 30 receives a selection operation on button B12, it generates a master data management image and displays the generated master data management image. Here, the master data management image is an image that receives operations to input, change, delete, etc. the master data described above. The server 30 can generate, change, delete, etc. master data in response to operations on the master data management image. When the server 30 generates master data, it stores the generated master data. Furthermore, when the server 30 changes the master data, it updates the stored master data to the changed master data.

[0034] The button B13 is a button for displaying a manual image. When the server 30 receives a selection operation for the button B13, the server 30 generates a manual image and displays the generated manual image. Here, the manual image is an image that receives an operation for displaying a manual on how to operate the molding management system 1.

[0035] Button B14 is a button that displays terminal image P2. When server 30 receives a selection operation on button B14, it generates terminal image P2 and displays the generated terminal image P2. Here, terminal image P2 is an image that receives an operation to execute each of the various update-related functions possessed by server 30. In other words, terminal image P2 is an image that receives an operation to display a desired image from among images that receive operations for each of a plurality of update-related functions. A certain type of update-related function is a function that inputs, changes, deletes, etc. information according to that type. Note that terminal image P2 may also be configured to receive an operation to execute functions other than update-related functions. Furthermore, functions other than update-related functions may be any functions.

[0036] Button B15 is a button that displays a user management image. When server 30 receives a selection operation on button B15, it generates a user management image and displays the generated user management image. Here, the user management image is an image that receives operations to input, change, delete, display, etc., information about a user among the information stored in server 30.

[0037] The button B16 is a button that accepts an operation to log out the terminal device 40 from the server 30. When the server 30 accepts a selection operation on the button B16, the server 30 logs out the terminal device 40.

[0038] In this embodiment, the dashboard image, the master data management image, the manual image, and the user management image will not be described.

[0039] Fig. 3 is a diagram showing an example of a terminal image P2. As shown in Fig. 3, the terminal image P2 includes buttons for accepting operations to execute each of a plurality of update-related functions. For example, the terminal image P2 includes buttons B21 and B22 as such buttons.

[0040] The button B21 is a button that accepts an operation to display a lot search image P3, which is an example of the lot search image described above. When the server 30 accepts a selection operation on the button B21, the server 30 generates the lot search image P3 and displays the generated lot search image P3.

[0041] Fig. 4 is a diagram showing an example of the lot search image P3. In the example shown in Fig. 4, the lot search image P3 includes a lot search area RG1, a search result display area RG2, and a processing button group area RG3.

[0042] The lot search area RG1 includes, for example, input fields F11 to F18, a button B31, and a button B32. Note that the lot search area RG1 may be configured to include other GUIs that can accept a lot search operation instead of some or all of these GUIs, or in addition to all of these GUIs. Here, the aforementioned lot search operation refers to an individual operation accepted by the lot search area RG1. Note that in the molding management system 1, searching for a lot means searching for lot information.

[0043] The input field F11 is a field where lot identification information that identifies a desired lot is entered by the user. In FIG. 4, the character string "Lot No." superimposed on the input field F11 is a character string that indicates to the user that the information entered in the input field F11 is lot identification information. In the example shown in FIG. 4, nothing is entered in the input field F11. Note that the lot identification information may be entered in the input field F11 by selecting the lot identification information from a pull-down menu, or by direct entry using an input device such as a keyboard.

[0044] The input field F12 is a field where process information indicating the work process currently being performed on the product of the desired lot by the user, among the various processes included in the production process. Therefore, in the example shown in FIG. 4, the process information is included in the lot-related information described above, and the lot can be searched for using the process information as a search key. The character string "Process" superimposed on the input field F12 in FIG. 4 indicates to the user that the information entered in the input field F12 is process information. In this example, nothing is entered in the input field F12. Note that the process information can be entered into the input field F12 by selecting the process information from a pull-down menu, or by direct input using an input device such as a keyboard.

[0045] The input field F13 is a field for inputting injection molding machine identification information that identifies the injection molding machine that molded the product lot desired by the user or the injection molding machine that will mold the product lot desired by the user. Therefore, in the example shown in FIG. 4, the lot-related information includes the injection molding machine identification information, and the lot can be searched for using the injection molding machine identification information as a search key. The character string "machine" superimposed on the input field F13 in FIG. 4 indicates to the user that the information entered in the input field F13 is injection molding machine identification information. In this example, nothing is entered in the input field F13. The injection molding machine identification information can be entered into the input field F13 by selecting the injection molding machine identification information from a pull-down menu or by directly entering it using an input device such as a keyboard.

[0046] The input field F14 is a field where the user inputs product type information indicating the type of product of the desired lot. Therefore, in the example shown in FIG. 4, the lot-related information includes product type information, and the lot can be searched for using the product type information as a search key. The character string "Item" superimposed on the input field F14 in FIG. 4 indicates to the user that the information input into the input field F14 is product type information. In this example, nothing is input into the input field F14. Note that the product type information can be input into the input field F14 by selecting the product type information from a pull-down menu, or by direct input using an input device such as a keyboard.

[0047] The input field F15 is a field where information identifying the higher-level group to which the desired lot belongs is entered. The following description will be given, as an example, of a case where the group is a production lot. For ease of explanation, the information will be referred to as production lot identification information. Therefore, in the example shown in FIG. 4, the lot-related information includes production lot identification information, and a lot can be searched for using the production lot identification information as a search key. The group may also be another group, such as the work shift of a manager who manages the production of the products of the lot. The character string "Job No." superimposed on the input field F15 in FIG. 4 indicates to the user that the information entered in the input field F15 is production lot identification information. In this example, nothing is entered in the input field F15. The production lot identification information may be entered in the input field F15 by selecting the production lot identification information from a pull-down menu or by directly entering it using an input device such as a keyboard.

[0048] The input field F16 is a field where lot status information indicating the desired lot status is entered by the user. Therefore, in the example shown in FIG. 4 , the lot-related information includes the lot status information, and a lot can be searched for using the lot status information as a search key. The character string "Lot Status" superimposed on the input field F16 in FIG. 4 indicates to the user that the information entered in the input field F16 is lot status information. In this example, nothing is entered in the input field F16. The lot status information indicates one of the following states: a lot is stopped, a lot is being prepared, a lot is waiting, or a lot is completed. Hereinafter, for convenience of explanation, a state in which a lot is stopped will be simply referred to as "lot stopped." Also, for convenience of explanation, a state in which a lot is being prepared will be simply referred to as "lot being prepared." Also, for convenience of explanation, a state in which a lot is waiting will be simply referred to as "lot waiting." For ease of explanation, the state in which a lot has been completed will be referred to simply as “lot completion.” Note that the input of lot status information into the input field F16 may be performed by selecting lot status information from a pull-down menu, or by direct input using an input device such as a keyboard.

[0049] Input fields F17 and F18 are fields where the user inputs period information indicating the period including the date when production of the desired lot of products began. Therefore, in the example shown in FIG. 4, the lot-related information includes information indicating the date, and the lot can be searched for using this information as a search key. The character string "Start Date of First Process from" superimposed on input field F17 in FIG. 4 indicates to the user that the information entered in input field F17 is start date and time information indicating the start date and time of the period. The character string "Start Date of First Process to" superimposed on input field F18 in FIG. 4 indicates to the user that the information entered in input field F18 is end date and time information indicating the end date and time of the period. In this example, nothing is entered in input fields F17 and F18. The start date and time information can be entered in input field F17 by selecting a date using a calendar or the like and a time using a clock or the like, or by direct input using an input device such as a keyboard. The end date and time information may be entered into the input field F18 by selecting the date using a calendar or the like, selecting the time using a clock or the like, or by direct input using an input device such as a keyboard. The start date and time information may be information indicating only the date and time. The end date and time information may be information indicating only the date and time.

[0050] The button B31 is a button that accepts an operation to delete the information entered in some or all of the input fields F11 to F18. In other words, the button B31 is a button that accepts an operation to clear the information entered in some or all of the input fields F11 to F18. When the button B31 is selected, the server 30 deletes the information entered in some or all of the input fields F11 to F18.

[0051] Button B32 is a button that accepts an operation to execute a search for a lot based on the information entered in some or all of input fields F11 to F18. When button B32 is selected, server 30 extracts one or more pieces of lot information that include the information entered in some or all of input fields F11 to F18 from one or more pieces of lot information stored in advance. After extracting one or more pieces of lot information, server 30 displays a list of the one or more pieces of extracted lot information in search result display area RG2. For ease of explanation, this list will be referred to below simply as a lot information list.

[0052] The search result display area RG2 is an area where a list of lot information is displayed as a result of a selection operation on the button B32. If no selection operation is performed on the button B32, the search result display area RG2 may display a list of all lot information stored in the server 30, or may display nothing. In the example shown in FIG. 4, the list is displayed in the search result display area RG2. The number of lot information items to be displayed in the search result display area RG2 may be determined in advance. In this case, the search result display area RG2 includes a button for displaying lot information that could not be displayed in the search result display area RG2.

[0053] In the example shown in FIG. 4, the lot information displayed in the search result display area RG2 includes lot identification information as well as some of the lot-related information. Specifically, the lot information includes lot identification information, production quantity information, production type information, process information, lot status information, and start date and time information. Note that the lot information may include all of the lot-related information along with the lot identification information. For example, the lot information displayed at the top of the search result display area RG2 shown in FIG. 4 includes lot identification information "1234567890," production quantity information "10," production type information "Part 1," process information "Shipping Inspection SB1," lot status information indicating lot completion, and start date and time information "2022-06-08 08:00." Here, "10" represents the production quantity information indicating 10 pieces. "2022-06-08 08:00" represents the start date and time information indicating 8:00 AM on June 8, 2022.

[0054] A detailed display button (not shown) is displayed in association with each piece of lot information displayed in the search result display area RG2. The detailed display button displayed in association with certain lot information is a button that accepts an operation to display a detailed information display image in which detailed information about the lot indicated by the lot information is displayed. The detailed information displayed in the detailed information display image includes at least a portion of the information contained in the lot information that is displayed in the search result display area RG2, and at least a portion of the information contained in the lot information that is not displayed in the search result display area RG2.

[0055] As described above, one or more pieces of information included in the lot-related information of a certain lot information are associated with the lot identification information included in the lot information. Therefore, the server 30 can extract the lot information from the storage area of ​​the server 30 using the lot identification information. This is useful because it not only simplifies the data structure of the lot information but also reduces the load on the server 30 in searching for lots.

[0056] Furthermore, when one or more pieces of lot information are displayed in the search result display area RG2, check boxes are displayed for accepting an operation to select each of the one or more pieces of lot information. For example, the check box C1 shown in FIG. 4 is a check box for accepting an operation to select the lot information displayed in the top row of the search result display area RG2. Note that the search result display area RG2 may also be configured to display check boxes for accepting an operation to select all of the lot information displayed in the search result display area RG2. This allows the server 30 to reduce the effort required for the user to select lot information. For convenience of explanation, the operation of selecting lot information via such check boxes will be referred to as a lot information selection operation below. Note that the selection of certain lot information may also be referred to as the selection of the lot indicated by that lot information.

[0057] The processing button group area RG3 is an area where a GUI is displayed that accepts a processing execution operation that causes the server 30 to start executing a predetermined process on each of the lots indicated by one or more pieces of lot information selected in response to a received lot information selection operation from among the one or more pieces of lot information displayed in the search result display area RG2. In the example shown in FIG. 4, 11 buttons are displayed as such a GUI in the processing button group area RG3. In this example, these 11 buttons include a button B41. In this embodiment, a description of the 11 buttons other than the button B41 will be omitted.

[0058] The button B41 is a button that accepts an operation to display a history information display image that displays history information included in the lot-related information of the lot information indicating the target lot, with the lot selected by the user in the search result display area RG2 as the target lot. If a predetermined first gray-out condition is met, the server 30 grays out the button B41 and does not accept any selection operation on the button B41. On the other hand, if the first gray-out condition is not met, the server 30 cancels the gray-out of the button B41 and accepts any selection operation on the button B41. By graying out the button in this manner, the server 30 can prevent erroneous operations by the user. The first gray-out condition is, for example, a condition that includes the following two conditions, condition 1A and condition 1B.

[0059] Condition 1A: Multiple lots are selected by the user in the search result display area RG2 Condition 1B: No lot has been selected by the user in the search result display area RG2

[0060] The server 30 determines that the first gray-out condition is met when either condition 1A or condition 1B is met. On the other hand, the server 30 determines that the first gray-out condition is not met when both condition 1A and condition 1B are not met.

[0061] 4, the user has selected the topmost lot among the multiple lots displayed in the search result display area RG2, and no other lots have been selected. Therefore, in this example, button B41 is not grayed out. Button B41 is an example of a second history information display image display operation acceptance image.

[0062] When a selection operation is performed on button B41, the server 30 identifies the lot selected by the user in the search result display area RG2 as the target lot, and displays a history information display image P4 that displays the history information included in the lot-related information of the lot information indicating the target lot.

[0063] 5 is a diagram showing an example of the overall image of the history information display image P4 that is displayed when a selection operation is performed on the button B41 shown in FIG. 5. In the example shown in FIG. 5, the history information display image P4 includes four areas, namely, display areas RG41 to RG44. The server 30 may be configured to display the history information display image P4 as one of the images included in the lot search image P3, or may be configured to display the history information display image P4 in a separate window, or may be configured to display the history information display image P4 by superimposing it on the lot search image P3, or may be configured to display the history information display image P4 in a pop-up, or may be configured to display the history information display image P4 by some other method.

[0064] Furthermore, in the example shown in Fig. 5, display regions RG41 to RG44 are arranged in the order of display region RG41, display region RG42, display region RG43, and display region RG44 from top to bottom in Fig. 5. Note that display regions RG41 to RG44 may be arranged in a different order, may be arranged in a different direction, or may be arranged in a different format.

[0065] FIG. 6 is an enlarged view of the display area RG41 shown in FIG. 5. The display area RG41 is an area where lot information change history information, which is one of various pieces of information included as history information in the lot-related information of the lot information indicating the target lot, is displayed. As described above, the lot information change history information is information that indicates the history of changes made to the lot information indicating the target lot. In other words, the lot information change history information is information that indicates the history of changes made by a user to at least one piece of information included in the lot information indicating the target lot. For example, if a user makes a change to information X included in the lot information indicating the target lot, the lot information change history information indicates the history of changes made to information X by the user. Information X may be any information included in the lot information indicating the target lot.

[0066] 6, the lot information change history information displayed in the display area RG41 includes lot information change date and time information, process information change history information, history type information, lot information changer information, equipment information, production number change history information, production number history information, lot information change reason information, and lot information change comment information.

Note that the lot information change history information displayed in the display area RG41 may include other information indicating the history of changes to the lot information for the target lot, instead of some or all of the above information, or in addition to all of the above information. Here, the lot information change date and time information included in certain lot information change history information is information indicating the date and time when the lot information including the lot information change history information was changed. The process information change history information included in the lot information change history information is information indicating the history of changes to the process information at the date and time indicated by the lot information change date and time information. Note that the process information change history information may be, for example, the process information included in the lot information at that date and time, or other information indicating the history of changes to the process information at that date and time. The history type information included in the lot information change history information is information indicating the type of change to the lot information made by the user. The lot information changer information included in the lot information change history information is information indicating the user who changed the lot information at that date and time. The equipment information included in the lot information change history information is information indicating the equipment that was performing work on the products of the target lot at that date and time. Note that the equipment information may be null information if there was no equipment performing work on the products of the target lot at that date and time, or may be other information indicating that there was no equipment performing work on the products of the target lot at that date and time.The production quantity change number history information included in the lot information change history information indicates the difference between the number indicated by the production quantity information before and after a change in the production quantity information of the lot information at a given date and time. The production quantity change number history information may be expressed as a positive or negative integer, or may be the production quantity information at that date and time. However, if the production quantity change number history information is the production quantity information, the number indicated by the production quantity change number history information matches the number indicated by the production quantity history information. The production quantity history information included in the lot information change history information indicates the history of changes to the production quantity information of the lot information at that date and time. The production quantity history information may be, for example, the production quantity information included in the lot information at that date and time, or other information indicating the history of changes to the production quantity information at that date and time. The lot information change reason information included in the lot information change history information indicates the reason the lot information was changed at that date and time. The lot information change comment information included in the lot information change history information indicates a comment regarding the change to the lot information at that date and time.

[0067] In the display area RG41 shown in FIG. 6, lot information change date and time information is indicated by "results registration date and time." In the display area RG41 shown in FIG. 6, process information change history information is indicated by "process." In the display area RG41 shown in FIG. 6, history type information is indicated by "history type." In the display area RG41 shown in FIG. 6, lot information change person information is indicated by "results registration worker."

In the display area RG41 shown in FIG. 6, lot information change reason information is indicated by "reason." In the display area RG41 shown in FIG. 6, lot information change comment information is indicated by "comment."

[0068] 6 includes "2023-08-24 08:00" as lot information change date and time information, "injection molding" as process information change history information, "lot creation" as history type information, "first user" as lot information changer information, null information as equipment information, "0" as production item quantity change history information, "0" as production item quantity change history information, "reason 1" as lot information change reason information, and "comment 1" as lot information change comment information. Here, "2023-08-24 08:00" indicates 8:00 on August 24, 2023. Furthermore, the "injection molding" is also process information included in the lot information indicating the target lot at 8:00 AM on August 24, 2023, indicating that the work process being performed on the products produced by the target lot at 8:00 AM on August 24, 2023 is the injection molding process. The "lot creation" indicates that the lot information was created as one of the changes to the lot information indicating the target lot. The "first user" indicates that the user who made the change to the lot information was the first user. The null information as equipment information in the lot information change history information indicates that there was no equipment performing work on the products produced by the lot indicated by the lot information at 8:00 AM on August 24, 2023. The "0" as the production item quantity change history information in the lot information change history information indicates that there was no change to the production item quantity information included in the lot information when the lot information was changed at 8:00 AM on August 24, 2023. The "0" as the production item quantity change history information in the lot information change history information also indicates that there was no change to the production item quantity information included in the lot information when the lot information was changed at 08:00 on August 24, 2023. The "Reason 1" indicates the reason why the lot information was changed at 08:00 on August 24, 2023. The "Comment 1" indicates a comment by the first user regarding the change to the lot information at 08:00 on August 24, 2023.

[0069] In this manner, the display area RG41 displays the lot information change history information included in the lot information indicating the target lot. For example, by comparing the lot information change history information displayed in the top row of the display area RG41 shown in FIG. 6 with the lot information change history information displayed in the second row from the top of the display area RG41 shown in FIG. 6, it can be seen that at 10:02 AM on August 24, 2023, the injection molding process for the target lot's products changed from not yet started to having started. This can be seen from the fact that the history type information is different when comparing these two pieces of lot information change history information. For example, by comparing the lot information change history information displayed in the second row from the top of the display area RG41 shown in FIG. 6 with the lot information change history information displayed in the third row from the top of the display area RG41 shown in FIG. 6, it can be seen that at 10:04 AM on August 24, 2023, the injection molding process for the target lot's products changed from having started to having completed. Therefore, in the lot information change history information displayed in the third row from the top of the display area RG41 shown in FIG. 6, the production quantity change history information is "10," indicating +10 units, and the production quantity change history information is "10," indicating 10 units. That is, in the example shown in FIG. 6, by looking at the display area RG41, it can be seen that 10 units of the target lot were molded in the injection molding process during the two-minute period from 10:02 AM on August 24, 2023 to 10:04 AM on August 24, 2023. Furthermore, for example, by comparing the lot information change history information displayed in the third row from the top of the display area RG41 shown in FIG. 6 with the lot information change history information displayed in the fourth row from the top of the display area RG41 shown in FIG. 6, it can be seen that at 12:27 PM on August 29, 2023, the work process for the target lot's products changed from the injection molding process to the visual inspection and packaging process, and that the visual inspection and packaging process changed from not being started to being started. Therefore, in the lot information change history information displayed in the fourth row from the top of the display area RG41 shown in FIG. 6, the equipment information is "Inspection machine 1" which indicates the inspection equipment.In the example shown in Figure 6, it can be seen by looking at display area RG41 that the number of products in the target lot has not changed between 10:04 on August 24, 2023 and 12:27 on August 29, 2023. As described above, by displaying the lot information change history information, the server 30 can allow the user to easily identify the date and time, work process, reason, comment, etc., when the number of products in the target lot was changed. In other words, by displaying the lot information change history information, the server 30 can improve the traceability of molded products.

[0070] The display area RG41 may be configured to allow the user to edit lot information change reason information, lot information change comment information, etc. In this case, for example, input of lot information change reason information into the display area RG41 may be performed by selecting lot information change reason information from a pull-down menu, or may be performed by direct input using an input device such as a keyboard. Also, in this case, input of lot information change comment information into the display area RG41 may be performed by selecting lot information change comment information from a pull-down menu, or may be performed by direct input using an input device such as a keyboard.

[0071] Additionally, in the display area RG41, a button for accepting an operation to display a quality inspection history information display image is displayed in association with each lot information change reason information. Here, the quality inspection history information display image refers to an image that displays quality inspection history information. For example, a button displayed in association with certain lot information change history information is a button that accepts an operation to display a quality inspection history information display image that displays the quality inspection history information included in the history information including the lot information change history information. Also, for example, the quality inspection history information display image is an image that displays the quality information of the target lot at the date and time indicated by the lot information change date and time information included in the lot information change history information as the quality inspection history information. Note that the quality information of the target lot refers to the quality information included in the lot information that indicates the target lot. In this case, the lot information includes one or more pieces of quality information including a timestamp indicating the date and time of generation. The button B51 shown in FIG. 5 is an example of a button that accepts this operation. In other words, the button B51 is an example of an image that accepts an operation to display quality inspection history information. Also, this operation is an example of an operation to display quality inspection history information. The quality inspection history information display image will be described later. However, when the server 30 receives a selection operation for the button B51, it generates a quality inspection history information display image that displays the quality inspection history information included in the history information including the lot information change reason information to which the button B51 is attached, and displays the generated quality inspection history information display image. Note that the quality inspection history information display image may also be an image that displays other information indicating the history of inspections of the quality of the products of the target lot as quality inspection history information.

[0072] Fig. 7 is an enlarged view of the display area RG42 shown in Fig. 5. The display area RG42 is an area where work process change history information is displayed, which is one of various types of information included as history information in the lot-related information of the lot information indicating the target lot. As described above, the work process change history information is information that indicates the history of changes to the work process that have been made to the products of the target lot.

[0073] In the example shown in FIG. 7, the work process change history information displayed in the display area RG42 includes process information, routing information, process start date and time information, and process end date and time information. That is, in this example, the history information of the lot information indicating the target lot includes each of the process information, routing information, process start date and time information, and process end date and time information as work process change history information. Note that the work process change history information displayed in the display area RG42 may include other information indicating the history of work process changes made to the products of the target lot, instead of some or all of this information, or in addition to all of this information. Here, the process information included in certain work process change history information is information indicating, among the work processes performed on the products of the target lot, the work process that started at the date and time indicated by the process start date and time information included in the work process change history information. In this case, the display area RG42 indicates that the work process performed on the products of the target lot has been changed due to a change in the process information in the list of process information displayed in the display area RG42. The routing information included in the work process change history information indicates the order of the work processes that started at the date and time indicated by the process start date and time information included in the work process change history information, as the order of the work processes among the multiple work processes performed on the product of the target lot. In this case, the display area RG42 indicates whether the work processes performed on the product of the target lot are being performed according to the routing date and time, based on how the routing information changes in the list of routing information displayed in the display area RG42. The process start date and time information included in the work process change history information indicates the date and time when the work process indicated by the process information included in the work process change history information started. The display area RG42 indicates whether the work process performed on the product of the target lot has started based on the presence or absence of process start date and time information. The process end date and time information included in the work process change history information indicates the date and time when the work process indicated by the process information included in the work process change history information ended. The display area RG42 indicates whether the work process performed on the product of the target lot has ended based on the presence or absence of process end date and time information.

[0074] In the display area RG42 shown in FIG. 7, process information is indicated by "Process." In the display area RG42 shown in FIG. 7, process order information is indicated by "Process Order." In the display area RG42 shown in FIG. 7, process start date and time information is indicated by "Start Date and Time." In the display area RG42 shown in FIG. 7, process end date and time information is indicated by "Completion Date and Time."

[0075] For example, the work process change history information displayed in the top row of the display area RG42 shown in FIG. 7 includes "injection molding" as process information, "1" as routing information, "2023-08-24 10:02" as process start date / time information, and "2023-08-24 10:04" as process end date / time information. Here, "injection molding" indicates the injection molding process that molds the product of the target lot. The "1" indicates that the injection molding process is first in the routing. The "2023-08-24 10:02" indicates that the injection molding process started at 10:02 on August 24, 2023. The "2023-08-24 10:04" indicates that the injection molding process ended at 10:04 on August 24, 2023.

[0076] In this way, the display area RG42 displays the work process change history information included in the lot information indicating the target lot. For example, comparing the work process change history information displayed in the top row of the display area RG42 shown in FIG. 7 with the work process change history information displayed in the second row from the top of the display area RG42 shown in FIG. 7, it can be seen that the injection molding process for the target lot's products ended at 10:04 AM on August 24, 2023, and the visual inspection and packaging process for the target lot's products began at 12:27 PM on August 29, 2023. Furthermore, for example, looking at the work process change history information displayed in the third row from the top of the display area RG42 shown in FIG. 7, it can be seen that the shipping inspection (sampling dimensional inspection) process, shipping inspection approval process, and parts warehouse delivery process for the target lot's products have not yet been performed. As described above, by displaying the work process change history information, the server 30 allows the user to easily identify the date and time when the work process performed on the target lot's products was changed. That is, the server 30 can improve the traceability of molded products by displaying the work process change history information.

[0077] Fig. 8 is an enlarged view of the display area RG43 shown in Fig. 5. The display area RG43 is an area where material history information is displayed, which is one of various types of information included as history information in the lot-related information of the lot information indicating the target lot. As described above, the material history information is information that indicates the history of the use of materials in the products of the target lot.

[0078] In the example shown in FIG. 8, the material history information displayed in the display area RG43 includes process information, material type information, material lot identification information, material usage amount information, and material usage amount unit information. In other words, in this example, the history information of the lot information indicating the target lot includes each of the process information, material type information, material lot identification information, material usage amount information, and material usage amount unit information as material history information. Note that the material history information displayed in the display area RG43 may include other information indicating the history of material usage for the target lot, instead of some or all of the above information, or in addition to all of the above information. Here, the process information included in a given material history information indicates which of multiple work processes performed on the target lot of products used the material for that product. The material type information included in the material history information indicates the type of material used in that work process. The material lot identification information included in the material history information is the material lot identification information assigned to that material. The material usage amount information included in the material history information indicates the amount of that material used in that work process. The material usage amount unit information included in the material history information is information that indicates the unit of the amount of the material used in the work process.

[0079] In the display area RG43 shown in FIG. 8, process information is indicated by "Process." In the display area RG43 shown in FIG. 8, material type information is indicated by "Material Item." In the display area RG43 shown in FIG. 8, material lot identification information is indicated by "Material Lot No." In the display area RG43 shown in FIG. 8, material usage amount information is indicated by "Number Used." In the display area RG43 shown in FIG. 8, material usage amount unit information is indicated by "Unit."

[0080] For example, the material history information displayed in the top row of the display area RG43 shown in Figure 8 includes "injection molding" as process information, "Material 1" as material type information, "12345671" as material lot identification information, "57.95" as material usage amount information, and "kg" as material usage amount unit information. Here, "injection molding" indicates the injection molding process for molding the product of the target lot. Also, "Material 1" indicates that the type of material used in the molding process is Material 1. Note that the material usage amount information and material usage amount unit information may be combined into one piece of information.

[0081] In this way, the display area RG43 displays the material history information included in the lot information indicating the target lot. For example, by viewing the list of material history information displayed in the display area RG43 shown in FIG. 8, the user can easily identify the work process in which the material was used among the work processes performed on the products of the target lot, and can also easily identify the material lot of the material used. This makes it easy for the administrator or other person to determine whether or not a material was used for a purpose unintended by the administrator, and to identify the work process, lot, etc. in which a material found to have a problem was used. In other words, by displaying the material history information, the server 30 can improve the traceability of molded products.

[0082] Fig. 9 is an enlarged view of the display area RG44 shown in Fig. 5. The display area RG44 is an area where the lot management history information, which is one of various types of information included as history information in the lot-related information of the lot information indicating the target lot, is displayed. As described above, the lot management history information is information that indicates the history related to the management of the target lot.

[0083] Here, the management of the target lot includes, for example, dividing the target lot into multiple lots, changing the number of products of the target lot, transferring products between the target lot and other lots, and combining other lots with the target lot, but is not limited to these. Note that any method may be used to manage the target lot. For simplicity's sake, the following description will be given of an example in which the management of the target lot involves only dividing the target lot into multiple lots. In this case, the lot management history information may be referred to as lot division history information, which indicates the history of dividing the target lot. Therefore, for convenience's sake, the lot management history information will be referred to as lot division history information in the following description.

[0084] 9, the lot division history information displayed in display area RG44 includes lot identification information that identifies the target lot before it was divided, production number information that indicates the number of products of the target lot before it was divided, lot identification information that indicates one of the lots into which the target lot was divided, and production number information that indicates the number of products of the lot indicated by the lot identification information. That is, in this example, the history information of the lot information indicating the target lot includes, as lot division history information, production number information that indicates the number of products of the target lot before it was divided, lot identification information that indicates one of the lots into which the target lot was divided, and production number information that indicates the number of products of the lot indicated by the lot identification information. Note that the lot division history information displayed in display area RG44 may be configured to include other information indicating the history of management of the target lot instead of some or all of this information, or in addition to all of this information.

[0085] In the display area RG44 shown in FIG. 9, lot identification information that identifies the target lot before it is divided is indicated by "before." For ease of explanation, this lot identification information will be referred to as "origin lot identification information" below. In the display area RG44 shown in FIG. 9, production item quantity information indicating the number of products of the target lot before it is divided is indicated by "quantity" located to the right of "before." For ease of explanation, this production item quantity information will be referred to as "origin production item quantity information." In the display area RG44 shown in FIG. 9, lot identification information indicating one of the lots into which the target lot is divided is indicated by "after." For ease of explanation, this lot identification information will be referred to as "destination lot identification information." In the display area RG44 shown in FIG. 9, production item quantity information indicating the number of products of the lot indicated by the destination lot identification information is indicated by "quantity" located to the right of "after." For ease of explanation, this production item quantity information will be referred to as "destination production item quantity information."

[0086] For example, the lot division history information displayed in the top row of the display area RG44 shown in Fig. 9 includes "1234567890" as the division-source lot identification information, "60" as the division-source production item quantity information, "1234567890" as the division-destination lot identification information, and "20" as the division-destination production item quantity information. Here, the "60" indicates that the number indicated by the division-source production item quantity information is 60. Here, the "20" indicates that the number indicated by the division-destination production item quantity information is 20.

[0087] The display area RG44 shown in FIG. 9 displays a list of three pieces of lot division history information. This indicates that the target lot indicated by the division-source lot identification information has been divided into three lots. Furthermore, the fact that the division-destination lot identification information displayed at the top of the display area RG44 is the division-source lot identification information means that the server 30 has matched the lot identification information of any one of these three lots with the lot identification information of the target lot. However, this is merely an example, and the server 30 may be configured to set the lot identification information of each of these three lots to be different from the division-source lot identification information. Furthermore, the server 30 may use any method to generate the lot identification information of each of these three lots.

[0088] In this way, the display area RG44 displays the lot division history information included in the lot information indicating the target lot. For example, by viewing the list of lot division history information displayed in the display area RG44 shown in FIG. 9, the user can easily identify the lot identification information for each of the three lots into which the target lot was divided. This makes it easy to identify the relationships between lots after they have been divided, which is an example of lot management. In other words, by displaying the material history information, the server 30 can improve the traceability of molded products.

[0089] 10 is a diagram showing an example of the quality inspection history information display image P5 displayed by the server 30 when the button B51 shown in FIG. 5 is selected. The server 30 may be configured to display the quality inspection history information display image P5 as one of the images included in the history information display image P4, or may be configured to display the quality inspection history information display image P5 in a separate window, or may be configured to superimpose the quality inspection history information display image P5 on the history information display image P4, or may be configured to display the quality inspection history information display image P5 in a pop-up, or may be configured to display the quality inspection history information display image P5 by some other method. In the example shown in FIG. 10, the quality inspection history information display image P5 is displayed in a pop-up on the history information display image P4.

[0090] 10, the quality inspection history information display image P5 includes display fields F21 to F24, a display region RG51, and a display region RG52. Note that the quality inspection history information display image P5 may be configured to include other GUIs related to the display of the quality inspection history information instead of some or all of these GUIs, or in addition to all of these GUIs.

[0091] Display field F21 is a field where lot identification information included in the lot information indicating the target lot is displayed. In Fig. 10, the character string "Lot ID" superimposed on display field F21 is a character string for indicating to the user that the information displayed in display field F21 is the lot identification information. In the example shown in Fig. 10, "1234567890" is displayed in display field F21 as the lot identification information.

[0092] Display field F22 is a field where product type information included in the lot information indicating the target lot is displayed. In Fig. 10, the character string "Item" superimposed on display field F22 is a character string for indicating to the user that the information displayed in display field F22 is the product type information. In the example shown in Fig. 10, "Product 1" is displayed in display field F22 as the product type information.

[0093] Display field F23 is a field where the injection molding apparatus identification information included in the lot information indicating the target lot is displayed. In Fig. 10, the character string "Molding apparatus" superimposed on display field F23 is a character string for indicating to the user that the information displayed in display field F23 is the injection molding apparatus identification information. In the example shown in Fig. 10, "A-1" is displayed in display field F23 as the injection molding apparatus identification information.

[0094] Display field F24 is a field where mold identification information included in the lot information indicating the target lot is displayed. In Fig. 10, the character string "Mold" superimposed on display field F24 is a character string that indicates to the user that the information displayed in display field F24 is the mold identification information. In the example shown in Fig. 10, "Mold 1" is displayed in display field F24 as the mold identification information.

[0095] Here, as described above, the quality inspection history information display image P5 is an image in which the quality inspection history information is displayed. In the example shown in Fig. 10, the quality inspection history information display image P5 displays the quality inspection history information as well as the defective product occurrence history information. In the quality inspection history information display image P5, a display area R51 is an area in which the quality inspection history information is displayed. In addition, in the quality inspection history information display image P5, a display area R52 is an area in which the defective product occurrence history information is displayed.

[0096] 10, the quality inspection history information displayed in the quality inspection history information display image P5 is the quality information of the target lot at the date and time indicated by the lot information change date and time information included in the lot information change history information displayed in association with button B51. In this example, the quality inspection history information, i.e., the quality information, includes: inspection item information indicating the types of items inspected for the quality of the products of the target lot; reference value information serving as a standard for comparing the inspection results of the items indicated by the inspection item information; upper limit value information indicating the upper limit of a predetermined range including the value indicated by the reference value information; lower limit value information indicating the lower limit of the predetermined range; inspection quantity information indicating the number of products inspected for the item; inspection value information indicating the average value of the inspection results of the item; inspection value unit information indicating the unit of the average value; and inspection result information indicating whether the inspection result of the item indicates a pass / fail product. In other words, in this example, the history information of the lot information indicating the target lot includes each of the inspection item information, reference value information, upper limit value information, lower limit value information, inspection quantity information, inspection value information, inspection value unit information, and inspection result information as quality inspection result information change history information in the quality information change history information. The predetermined range refers to a range that includes values ​​obtained as inspection results when the corresponding item is inspected on non-defective products. The quality inspection history information displayed in the display area RG51 may include other information indicating the history of quality inspections of the products of the target lot, instead of some or all of the above information, or in addition to all of the above information. The quality inspection history information displayed in the quality inspection history information display image P5 may be different from the quality information of the target lot at the date and time indicated by the lot information change date and time information included in the lot information change history information displayed in association with the button B51, as long as the information is capable of indicating the history of quality inspections of the products of the target lot at the date and time indicated by the lot information change date and time information included in the lot information change history information displayed in association with the button B51.

[0097] In the display area RG51 shown in FIG. 10, test item information is indicated by "characteristics." In the display area RG51 shown in FIG. 10, reference value information is indicated by "standard value." In the display area RG51 shown in FIG. 10, upper limit value information is indicated by "standard upper limit." In the display area RG51 shown in FIG. 10, lower limit value information is indicated by "standard lower limit." In the display area RG51 shown in FIG. 10, test number information is indicated by "sampling No." In the display area RG51 shown in FIG. 10, test value information is indicated by "value." In the display area RG51 shown in FIG. 10, test value unit information is indicated by "unit." In the display area RG51 shown in FIG. 10, test result information is indicated by "test result."

[0098] For example, the quality inspection history information displayed in the top row of the display area RG51 shown in FIG. 10 includes "Characteristic 1" as inspection item information, "10.0" as reference value information, "10.5" as upper limit value information, "9.5" as lower limit value information, "3" as number of inspections information, "10.2" as inspection value information, "mm" as inspection value unit information, and "OK" as inspection result information. Here, "Characteristic 1" indicates that the type of item inspected for the quality of the products in the target lot is Characteristic 1. "10.0" indicates that the value indicated by the reference value information is 10.0. "10.5" indicates that the value indicated by the upper limit value information is 10.5. "9.5" indicates that the value indicated by the lower limit value information is 9.5. "3" indicates that the number indicated by the number of inspections information is 3. "10.2" indicates that the value indicated by the inspection value information is 10.2. The "mm" indicates that the unit indicated by the inspection value unit information is millimeters. The "OK" indicates that the inspection result indicated by the inspection result information is a non-defective product.

[0099] In this way, the display area RG51 displays the quality inspection history information included in the lot information indicating the target lot. By comparing the individual quality inspection history information display images that can be displayed in the display area RG41 shown in FIG. 6, for example, the user can easily identify the date and time, work process, and inspection item at which the quality information indicating the quality of the products of the target lot changed. This is important because it not only facilitates quality control tasks but also makes it easier to identify the cause of quality degradation in the case of a quality deterioration in the products of the target lot. In other words, this can be said to improve the traceability of the products of the target lot. As described above, the server 30 can improve the traceability of molded products by displaying quality inspection history information display images such as the quality inspection history information display image P5 shown in FIG. 10.

[0100] The defective product occurrence history information displayed in the display area RG52 is information indicating the history of defective product occurrence during quality inspection of the products of the target lot. In the example shown in FIG. 10, the defective product occurrence history information displayed in the quality inspection history information display image P5 is information including defective product number information indicating the number of defective products included in the products of the target lot at the date and time indicated by the lot information change date and time information included in the lot information change history information displayed in association with the button B51. In this example, the defective product occurrence history information includes defect reason type identification information that identifies the type of reason why the defective products included in the products of the target lot were determined to be defective, defect reason information indicating the reason, and defective product number information. That is, in this example, the lot information history information indicating the target lot includes the defect reason type identification information, defect reason information, and defective product number information as the defective product occurrence history information of the quality information change history information. Note that the defective product occurrence history information displayed in the display area RG52 may include other information indicating the history of defective product occurrence during quality inspection of the products of the target lot, instead of or in addition to some or all of the above information.

[0101] In the display area RG52 shown in Fig. 10, defect reason type identification information is shown by "defect ID." In addition, in the display area RG52 shown in Fig. 10, defect reason information is shown by "defect name." In addition, in the display area RG52 shown in Fig. 10, defective item quantity information is shown by "defect number."

[0102] For example, the defective product occurrence history information displayed in the top row of the display area RG52 shown in Fig. 10 includes "Defect 1" as the defect reason type identification information, "burr" as the defect reason information, and "2" as the defective product number information. Here, "Defect 1" indicates that the defect reason type identification information that identifies the type of reason why a defective product included in the products produced in the target lot was determined to be defective is "Defect 1." Furthermore, "burr" indicates that the reason in question was that a burr had formed on the outer periphery of the product. The "2" indicates that the number of defective products due to that reason was two.

[0103] In this way, the display area RG52 displays the defective product occurrence history information. By comparing the individual quality inspection history information display images that can be displayed in the display area RG41 shown in FIG. 6, for example, the user can easily identify the date and time, work process, and inspection item when the number of defective products in the target lot changed. This is also important because it not only facilitates the quality control process but also makes it easier to identify the cause of quality degradation when the quality of the target lot deteriorates. In other words, this can be said to improve the traceability of the target lot's products. As described above, the server 30 can improve the traceability of molded products by displaying quality inspection history information display images such as the quality inspection history information display image P5 shown in FIG. 10.

[0104] In this embodiment, since the defective product occurrence history information is displayed in the display area RG52, the lot information indicating the target lot includes the defective product occurrence history information. Here, in the server 30, the defective product occurrence history information may be handled together with the quality inspection history information as a single piece of information. That is, when the quality information is handled as the quality inspection history information as shown in FIG. 10, the defective product occurrence history information may be handled together with the quality information as a single piece of information.

[0105] 10, the display area RG52 may include a display field F31. The display field F31 is a field that displays the total number indicated by the defective product quantity information included in each piece of defective product occurrence history information displayed in the display area RG52. For this reason, in FIG. 10, the display field F31 displays "3" indicating three. Note that the display area RG52 may not include the display field F31.

[0106] Returning to FIG. 3, the button B22 is a button that accepts an operation to display a history information display operation acceptance image P6. Here, the history information display operation acceptance image P6 is an image that accepts an operation to display a history information display image P4 using the lot identification information of the target lot. When the server 30 accepts a selection operation on the button B22, it generates a history information display operation acceptance image P6 and displays the generated history information display operation acceptance image P6. Note that the button B22 is an example of a first history information display image display operation acceptance image. Also, the history information display operation acceptance image P6 is an example of an image that accepts an operation to display a history information display image.

[0107] Fig. 11 is a diagram showing an example of a history information display operation acceptance image P6. In the example shown in Fig. 11, the history information display operation acceptance image P6 includes, for example, an input field F41 and a button B61. Note that the history information display operation acceptance image P6 may be configured to include another GUI instead of one or both of these, or in addition to both of these.

[0108] The input field F41 is a field where lot identification information that identifies a lot designated by the user as the target lot is entered. In FIG. 11, the character string "Lot No." superimposed on the input field F41 is a character string that indicates to the user that the information entered in the input field F41 is the lot identification information. In the example shown in FIG. 11, nothing is entered in the input field F41. Note that the lot identification information may be entered in the input field F41 by selecting the lot identification information from a pull-down menu, or by direct entry using an input device such as a keyboard.

[0109] The button B61 is a button that accepts an operation to confirm the lot identification information entered in the input field F41 as the lot identification information that identifies the target lot and to display the history information display image P4. When a selection operation is performed on the button B61, the server 30 confirms the lot identification information entered in the input field F41 as the lot identification information that identifies the target lot. The server 30 then deletes the display of the history information display operation acceptance image P6 and displays the history information display image P4. Here, if a predetermined second gray-out condition is satisfied, the server 30 grays out the button B61 and does not accept a selection operation on the button B61. On the other hand, if the second gray-out condition is not satisfied, the server 30 cancels the gray-out of the button B61 and accepts a selection operation on the button B61. By graying out the button in this manner, the server 30 can prevent erroneous operations by the user. The second gray-out condition is, for example, a condition that includes the following condition 2A.

[0110] Condition 2A: Lot identification information is not entered in input field F41

[0111] If condition 2A is satisfied, the server 30 determines that the second gray-out condition is satisfied. On the other hand, if condition 2A is not satisfied, the server 30 determines that the second gray-out condition is not satisfied.

[0112] 11, as described above, no lot identification information has been entered in the input field F41, and therefore the button B61 is grayed out in this example.

[0113] The server 30 capable of displaying images such as the history information display image P4 on the terminal device 40 as described above is, for example, a workstation, a desktop PC (Personal Computer), a notebook PC, etc., but is not limited to these. The server 30 may be configured integrally with the information processing device 20.

[0114] The server 30 is communicably connected to the information processing device 20 via wired or wireless communication. The communication network connecting the server 30 and the information processing device 20 may be, for example, a LAN within a facility where multiple managed devices 10 are installed, the Internet, a mobile communication network, or another communication network. In the following, as an example, a case will be described in which the communication network connecting the server 30 and the information processing device 20 is the Internet. In this case, the server 30 is a cloud server.

[0115] Furthermore, the server 30 is communicably connected to the terminal device 40 via wired or wireless communication. In the example shown in FIG. 1, the server 30 is communicably connected to the terminal device 40 via wireless communication. The communication network connecting the server 30 and the terminal device 40 may be, for example, a LAN within the facility where the server 30 is installed, the Internet, a mobile communication network, or another communication network. In the following, as an example, a case will be described in which the communication network connecting the server 30 and the terminal device 40 is the Internet.

[0116] <Server hardware configuration> The hardware configuration of the server 30 will be described below with reference to Fig. 12. Fig. 12 is a diagram showing an example of the hardware configuration of the server 30.

[0117] The server 30 includes, for example, a processor 31, a storage unit 32, and a communication unit 33. These components are connected to each other via a bus so that they can communicate with each other. The server 30 also communicates with the information processing device 20 and the terminal device 40 via the communication unit 33.

[0118] The processor 31 is, for example, a CPU (Central Processing Unit). Note that instead of a CPU, the processor 31 may be another processor such as an FPGA (Field Programmable Gate Array). The processor 31 executes various programs stored in the storage unit 32.

[0119] The storage unit 32 is a storage device including, for example, a hard disk drive (HDD), a solid state drive (SSD), an electrically erasable programmable read-only memory (EEPROM), a read-only memory (ROM), and a random access memory (RAM). Note that instead of being built into the server 30, the storage unit 32 may be an external storage device connected via a digital input / output port such as a universal serial bus (USB). The storage unit 32 stores various types of information, images, and programs processed by the server 30. In other words, the various types of information stored by the server 30 are stored in the storage unit 32.

[0120] The communication unit 33 is a communication device that includes, for example, a digital input / output port such as a USB, an Ethernet (registered trademark) port, an antenna for wireless communication, and the like.

[0121] <Server functional configuration> The functional configuration of the server 30 will be described below with reference to Fig. 13. Fig. 13 is a diagram showing an example of the functional configuration of the server 30.

[0122] The server 30 includes a storage unit 32, a communication unit 33, and a control unit .

[0123] The control unit 34 controls the entire server 30. The control unit 34 includes a reception unit 341, an acquisition unit 342, and a display control unit 343. These functional units included in the control unit 34 are realized, for example, by the processor 31 executing various programs stored in the storage unit 32. Some or all of these functional units may be hardware functional units such as LSI (Large Scale Integration) or ASIC (Application Specific Integrated Circuit).

[0124] The reception unit 341 receives various information and various operations from devices connected to the server 30 so as to be able to communicate with the server 30 .

[0125] The acquiring unit 342 acquires, for each of the multiple managed devices 10, status information about the managed device 10 from the managed device 10 via the information processing device 20. The acquiring unit 342 may be configured to acquire the status information directly from the managed device 10 without going through the information processing device 20.

[0126] The display control unit 343 generates various images in response to operations received via the receiving unit 341. The display control unit 343 transmits the generated images to the terminal device 40 and causes the terminal device 40 to display the images.

[0127] <Processing by the server to display the history information display image> Referring to FIG. 14, a process in which the server 30 displays the history information display image P4 will be described. For ease of explanation, the lot search image P3 or the history information display operation acceptance image P6 will be referred to as the target image in the following description. FIG. 14 is a diagram showing an example of the flow of a process in which the server 30 displays the history information display image P4. As an example, the following describes a case in which the target image is displayed on the terminal device 40 at a timing before the processing of step S110 shown in FIG. 14 is performed. Also, as an example, the following describes a case in which lot information has already been stored in the server 30 at that timing.

[0128] The control unit 34 waits until it receives an operation to display the target image via the terminal device 40, that is, a selection operation on the button B21 or the button B22 (step S110). In Fig. 14, the process of step S110 is indicated by "display target image?"

[0129] When it is determined that an operation to display a target image has been received via the terminal device 40 (step S110—YES), the control unit 34 generates the target image (step S120). The method for generating the target image in step S120 may be a known method or a method to be developed in the future.

[0130] Next, the control unit 34 transmits the target image generated in step S120 to the terminal device 40, and causes the terminal device 40 to display the target image (step S130).

[0131] Next, the control unit 34 waits until an operation is received via the target image displayed on the terminal device 40 (step S140). In Fig. 14, the process of step S140 is indicated by "operation received?".

[0132] When the control unit 34 determines that an operation has been received via the target image displayed on the terminal device 40 (step S140-YES), the control unit 34 determines whether the received operation is an operation that ends the processing of the flowchart shown in Fig. 14 (step S150). The determination processing of step S150 by the control unit 34 may be performed by a known method or a method to be developed in the future. In Fig. 14, the processing of step S150 is indicated by "End?"

[0133] If the control unit 34 determines that the operation received in step S140 is an operation that ends the processing of the flowchart shown in FIG. 14 (step S150-YES), for example, the control unit 34 deletes the display of the target image from the terminal device 40 and ends the processing of the flowchart shown in FIG. 14.

[0134] On the other hand, if the control unit 34 determines in step S140 that the operation received is not an operation that ends the processing of the flowchart shown in FIG. 14 (step S150-NO), it performs processing according to the received operation (step S160). This processing includes processing for displaying a history information display image P4. Here, the processing performed by the control unit 34 in step S160 has already been described in the descriptions of FIGS. 4 and 11, and therefore a detailed description thereof will be omitted. Furthermore, the details of the history information display image P4 displayed by the processing of step S160 have already been described in FIGS. 5 to 10, and therefore a detailed description thereof will be omitted.

[0135] After the process of step S160 is performed, the control unit 34 transitions to step S140 and waits again until an operation is received via the target image displayed on the terminal device 40.

[0136] Through the above-described processing, the server 30 causes the terminal device 40 to display a history information display image P4 that displays history information included in the lot-related information of the lot information indicating the target lot selected from the lots indicated by one or more pieces of lot information stored in the storage unit 32. This enables the server 30 to improve the traceability of molded products.

[0137] The molding management system 1 described above may be configured to include a terminal device 40.

[0138] The method of displaying the history information display image P4 via the history information display operation acceptance image P6 described above is a method used in cases where, for example, an item tag on which lot identification information for identifying the target lot is written and a lot label on which a barcode or the like indicating the lot identification information is printed are available. On the other hand, the method of displaying the history information display image P4 via the lot search image P3 described above is a method used in cases where, for example, a production engineer in an office is operating the terminal device 40 but the lot label is not available.

[0139] Furthermore, the search for a lot described above may be performed using a time period during which the lot was not operating normally as a search key. In this case, the lot-related information includes information indicating that time period.

[0140] Furthermore, the search for a lot described above may be performed using one or more pieces of information included in the injection molding apparatus-related information as a search key. In this case, the lot-related information includes injection molding apparatus-related information. The injection molding apparatus-related information included in the lot-related information for a certain lot is information about the injection molding apparatus that molds the products of that lot, and as described above, this information includes, for example, operating status information indicating the operating status of the injection molding apparatus, detection information about the injection molding apparatus, etc. This allows server 30 to more reliably improve the traceability of the products.

[0141] Furthermore, the above-described lot search may be performed using an arbitrary character string as a search key. In this case, when the server 30 receives an arbitrary character string, it identifies information containing the received character string from one or more pieces of information included in the lot-related information, and displays a list of lot information indicating the lots identified by each piece of lot identification information associated with the identified information. This allows the server 30 to more easily search for lots by the user.

[0142] Furthermore, the above-described contents may be combined in any manner.
