[0009] The first control unit 111 is configured by a computer including a first processing unit 120 and a first storage unit 130. The first processing unit 120 includes one or more processors. The first processing unit 120 controls the operation of the first molding device 101 by executing a program stored in the first storage unit 130. The first storage unit 130 includes a volatile memory such as a RAM and a non-volatile memory such as a ROM. The first communication unit 112 includes a communication circuit for controlling communication with other devices such as the management server 200. The mold drive unit 113 opens and closes a mold having a cavity attached to the mold drive unit 113. The mold may be made of metal, ceramic, or resin. A metal mold is called a mold. The injection unit 114 injects a molding material obtained by plasticizing a material into a cavity of the mold. Various screens are displayed on the first display unit 115. The first display unit 115 includes, for example, a display.

[0010] The first processing unit 120 acquires molding conditions, production job information, maintenance conditions, etc. from the cloud server 300 via the management server 200, and stores them in the first storage unit 130. Based on the acquired molding conditions and production job information, the first processing unit 120 controls the mold driving unit 113 and the injection unit 114 to perform injection molding and mold a molded product. Specifically, the first processing unit 120 controls the mold driving unit 113 to clamp the mold, and controls the injection unit 114 to inject the modeling material into the mold, thereby molding a molded product having a shape corresponding to the shape of a cavity provided in the mold.

[0011] The first processing unit 120 includes a first acquisition unit 121, a first transmission unit 122, and a deletion unit 123. The first acquisition unit 121, the first transmission unit 122, and the deletion unit 123 are realized by the first processing unit 120 executing a program stored in the first storage unit 130. These may also be realized by circuits.

[0012] The first acquisition unit 121 acquires production data, which is data related to the production of molded products, such as production results of molded products, abnormality notifications, and the operating status of the molding device 100, and stores the data in the first storage unit .

[0013] The first transmission unit 122 transmits the production data stored in the first storage unit 130 to the management server 200. The first transmission unit 122 transmits the production data to the management server 200, for example, every time the production of a specific molded product is completed, or every time the production of a specific manufacturing lot of the molded product is completed.

[0014] The deletion unit 123 deletes from the first storage unit 130 production data for which a predetermined period of time has elapsed since it was stored in the first storage unit 130. The predetermined period of time is, for example, one week or one month.

[0015] The first display unit 115 displays the production data stored in the first storage unit 130. The first display unit 115 may display molding conditions, production job information, maintenance conditions, and the like stored in the first storage unit 130.

[0016] The second molding device 102 shown in Fig. 1 has the same configuration as the first molding device 101. Therefore, detailed description of the second molding device 102 will be omitted. In the following, when there is no need to distinguish between the molding devices, they will simply be referred to as molding devices 100. Note that the molding management system 10 may include three or more molding devices 100.

[0017] The management server 200 is configured by a computer including a second processing unit 201, a second storage unit 202, and a second communication unit 203. The second processing unit 201 includes one or more processors. The second processing unit 201 controls the operation of the management server 200 by executing a program stored in the second storage unit 202. The second storage unit 202 includes a main storage unit such as a RAM, and an auxiliary storage unit such as a hard disk drive. The second communication unit 203 includes a communication circuit for controlling communication with other devices such as the cloud server 300 and the molding device 100. The management server 200 may be configured by multiple computers.

[0018] The second processing unit 201 acquires the production data transmitted from the molding apparatus 100, and transmits the acquired production data to the cloud server 300. The production data acquired by the second processing unit 201 may be stored in the second storage unit 202.

[0019] The cloud server 300 is a server used via the Internet IN. The cloud server 300 includes a third processing unit 301, a third storage unit 302, and a third communication unit 303. The second storage unit 202 of the management server 200 and the third storage unit 302 of the cloud server 300 are collectively referred to as a storage unit. The management server 200 and the cloud server 300 may be configured as a single server.

[0020] The third processing unit 301 includes a second acquisition unit 310 and a reception unit 320. The second acquisition unit 310 and the reception unit 320 are realized by the third processing unit 301 executing a program stored in the third storage unit 302.

[0021] The second acquisition unit 310 acquires the production data transmitted to the management server 200 by the first transmission unit 122 of the molding apparatus 100. That is, the second acquisition unit 310 acquires the production data from the molding apparatus 100 via the management server 200. The production data acquired by the second acquisition unit 310 is stored in the third storage unit 302.

[0022] The reception unit 320 receives the selection of the molding apparatus 100 .

[0023] FIG. 3 is an explanatory diagram showing a schematic configuration of the first terminal device 401. The first terminal device 401 is configured as a computer including a fourth processing unit 410, a fourth storage unit 420, a fourth communication unit 430, a second display unit 440, and an input unit 450. The first terminal device 401 is, for example, a notebook computer, a tablet terminal, a smartphone, a handheld terminal, or the like. The fourth processing unit 410 includes one or more processors. The fourth processing unit 410 controls the operation of the first terminal device 401 by executing a program stored in the fourth storage unit 420. The fourth storage unit 420 includes a main storage unit such as a RAM and an auxiliary storage unit such as a hard disk drive. The fourth communication unit 430 includes a communication circuit for controlling communication with other devices such as the cloud server 300. The second display unit 440 displays various screens. The second display unit 440 includes, for example, a liquid crystal display. The input unit 450 accepts input from a user. The input unit 450 is configured with, for example, a mouse and a keyboard. The second display unit 440 and the input unit 450 may be integrated as a touch panel.

[0024] The fourth processing unit 410 includes a third acquisition unit 411. The third acquisition unit 411 is realized by the fourth processing unit 410 executing a program stored in the fourth storage unit 420.

[0025] The third acquisition unit 411 acquires, from the cloud server 300, information relating to the production data stored in the third storage unit 302 of the cloud server 300.

[0026] The second terminal device 402 shown in Fig. 1 has the same configuration as the first terminal device 401. Therefore, detailed description of the second terminal device 402 will be omitted. In the following, when each terminal device is referred to without distinction, it will be simply referred to as the terminal device 400. It is preferable that the molding management system 10 has the same number of terminal devices 400 as the molding devices 100. The molding management system 10 may have one terminal device 400, or three or more terminal devices 400.

[0027] A user logs in to the server using the terminal device 400. For example, the user accesses the cloud server 300 by starting a web browser on the terminal device 400 and inputting a URL. When the cloud server 300 receives a connection request from the terminal device 400, it transmits a login screen to the terminal device 400. The terminal device 400 transmits the user ID and password input by the user on the login screen to the cloud server 300. If the received user ID and password match a pre-registered user ID and password, the cloud server 300 authenticates the user's login, and if they do not match, it does not authenticate the user's login. If the user's login is authenticated, a menu screen SC1 is displayed on the second display unit 440. In the following, it is assumed that the user's login to the server is authenticated.

[0028] 4 is a diagram showing the menu screen SC1. On the menu screen SC1, items A to D, which are the names of production data items, are displayed. For example, item A is the remaining amount of material in the molding device 100, and item B is the inspection result of the molding device 100. Also, on the menu screen SC1, a selection field BX1 is provided so as to be able to be displayed. The selection field BX1 is displayed on the menu screen SC1 when the user selects a button BT1 provided on the menu screen SC1.

[0029] 5 is a process diagram of the display setting process executed by the molding management system 10. The display setting process is a process for setting the molding apparatus 100 in which production data is displayed on the second display unit 440 of the terminal device 400.

[0030] In step S10, the fourth processing unit 410 of the terminal device 400 displays a device selection screen SC2 on the second display unit 440. The device selection screen SC2 is preferably displayed as a pop-up on the second display unit 440. Step S10 is executed when the user selects "Device Selection" from the selection field BX1 on the menu screen SC1. When "Device Selection" is selected, the terminal device 400 transmits a display request for the device selection screen SC2 to the cloud server 300. When the cloud server 300 receives the display request for the device selection screen SC2, it transmits data of the device selection screen SC2 to the terminal device 400.

[0031] 6 is a diagram showing an apparatus selection screen SC2. An apparatus selection field BX2 is provided on the apparatus selection screen SC2. The apparatus selection field BX2 is provided so that a list of molding apparatuses 100 included in the molding management system 10 is displayed when the user selects the apparatus selection field BX2.

[0032] In step S20 of Fig. 5, the reception unit 320 of the cloud server 300 receives a selection of a molding apparatus 100 from a user. When the user selects the selection button BT2 with a specific molding apparatus 100 selected on the apparatus selection screen SC2, the terminal device 400 transmits information to the cloud server 300 that the specific molding apparatus 100 has been selected. The reception unit 320 receives the above-mentioned information to receive the selection of a molding apparatus 100 from the user. Here, it is assumed that the user selects the first molding apparatus 101 on the apparatus selection screen SC2 displayed on the first terminal device 401, and selects the second molding apparatus 102 on the apparatus selection screen SC2 displayed on the second terminal device 402.

[0033] In step S30, the third acquisition unit 411 of the terminal device 400 acquires information related to the production data of the molding apparatus 100 selected in step S20 from the cloud server 300. Here, the information related to the production data is screen data for displaying the production data on the second display unit 440 of the terminal device 400. Specifically, the third acquisition unit 411 acquires data of a menu screen SC3, which will be described later. Note that in step S30, the third acquisition unit 411 may acquire the production data of the molding apparatus 100 selected in step S20 from the third storage unit 302 of the cloud server 300.

[0034] In step S40, the fourth processing unit 410 of the terminal device 400 displays the production data on the second display unit 440 based on the information on the production data of the molding device 100 acquired by the third acquisition unit 411 in step S30. Here, the production data displayed on the second display unit 440 is the production data stored in the third storage unit 302 of the cloud server 300. Specifically, the fourth processing unit 410 displays the menu screen SC3 on which the production data is displayed on the second display unit 440 based on the data of the menu screen SC3. That is, the fourth processing unit 410 displays the production data of the molding device 100 selected in step S20 on the second display unit 440, and restricts the production data of the molding device 100 not selected in step S20 from being displayed on the second display unit 440. Therefore, the production data of the first molding device 101 is displayed on the second display unit 440 of the first terminal device 401, but the production data of the second molding device 102 is not displayed. Furthermore, the second display unit 440 of the second terminal device 402 displays the production data of the second molding apparatus 102, but does not display the production data of the first molding apparatus 101. When the third acquisition unit 411 acquires the production data of the molding apparatus 100 from the third storage unit 302 of the cloud server 300 in step S30, the fourth processing unit 410 may cause the second display unit 440 to display the production data acquired by the third acquisition unit 411.

[0035] FIG. 7 is a diagram showing an example of a menu screen SC3 displayed on the second display unit 440 of the terminal device 400 in step S40 of FIG. 5. FIG. 7 shows the menu screen SC3 displayed on the second display unit 440 of the first terminal device 401. The menu screen SC3 displays the name of the first molding device 101, which is the molding device 100 selected in step S20 of FIG. 5. The menu screen SC3 also displays the production data of the first molding device 101 so as to overlap the names of the items of the respective production data. In the example shown in FIG. 7, the remaining amount of material in the first molding device 101 is displayed so as to overlap item A, and the progress status of the inspection of the first molding device 101 is displayed so as to overlap item B. In the example of the inspection progress status shown in FIG. 7, it is shown that 0 out of 3 inspection items have been completed.

[0036] According to the molding management system 10 in the first embodiment described above, the second acquisition unit 310 of the cloud server 300 acquires production data from the molding apparatus 100 via the management server 200, and stores the acquired production data in the third storage unit 302 of the cloud server 300. The second display unit 440 of the terminal device 400 displays the production data stored in the third storage unit 302 of the cloud server 300. Therefore, when the period during which the production data is stored differs depending on the molding apparatus 100, it is possible to suppress the production data displayed on the second display unit 440 of the terminal device 400 from differing depending on the molding apparatus 100. In the following, an example will be described in which the period during which the production data is stored in the first molding apparatus 101 is two weeks, and the period during which the production data is stored in the second molding apparatus 102 is one week. In this case, the production data of the first molding device 101 from two weeks ago is stored in the first storage unit 130 of the first molding device 101, but the production data of the second molding device 102 from two weeks ago is not stored in the first storage unit 130 of the second molding device 102. Therefore, the production data from two weeks ago is displayed on the first display unit 115 of the first molding device 101, but the production data from two weeks ago is not displayed on the first display unit 115 of the second molding device 102. However, the production data from two weeks ago of the first molding device 101 and the second molding device 102 is stored in the third storage unit 302 of the cloud server 300. Therefore, the production data from two weeks ago of the first molding device 101 can be displayed on the second display unit 440 of the first terminal device 401, and the production data from two weeks ago of the second molding device 102 can be displayed on the second display unit 440 of the second terminal device 402. In this manner, when the period during which production data is stored differs depending on the molding apparatus 100, it is possible to prevent the data displayed on the second display unit 440 of the terminal device 400 from differing depending on the molding apparatus 100.

[0037] As described above, the third storage unit 302 of the cloud server 300 stores production data that is not stored in the first storage unit 130 of the molding apparatus 100. Therefore, the user can check the production data that is not displayed on the first display unit 115 of the molding apparatus 100 on the terminal device 400.

[0038] In this embodiment, the production data of the molding apparatus 100 selected by the user is displayed on the second display unit 440 of the terminal device 400, and the display of the production data of the molding apparatus 100 not selected by the user is restricted. Therefore, the user can select the molding apparatus 100 for which the production data is to be displayed on the terminal device 400.

[0039] Furthermore, in this embodiment, the deletion unit 123 of the molding apparatus 100 deletes from the first storage unit 130 production data that has been stored in the first storage unit 130 for a predetermined period of time. This increases the available capacity of the first storage unit 130, and as a result, reduces the decrease in the processing capacity of the molding apparatus 100. For example, when the door of the molding apparatus 100 is unlocked while the molding apparatus 100 is in operation, it reduces delays in the decision to make an emergency stop of the molding apparatus 100.

[0040] B. Second embodiment: In the second embodiment, the operating status screen SC4 is displayed on the second display unit 440 of the terminal device 400. The configuration of each part of the molding management system 10 in the second embodiment is the same as that in the first embodiment. In the second embodiment, it is preferable that the molding management system 10 includes a smaller number of terminal devices 400 than the molding devices 100.

[0041] 8 to 11 are diagrams showing the operation status screen SC4. The operation status screen SC4 is displayed on the second display unit 440 of the terminal device 400 while the factory equipped with the molding apparatus 100 is operating and while the terminal device 400 is not accepting operations from the user. In the example shown in Fig. 8 to 11, the operation status screen SC4 displays the molding apparatus 100 arranged on the large product line of the factory.

[0042] First, a process of accepting cancellation of the selection of the molding apparatus 100 from the user will be described with reference to FIG. 8 and FIG. 9. The name of the molding apparatus 100 selected by the user is displayed on the operation status screen SC4 shown in FIG. 8. A button BT3 is provided in each area where the name of the molding apparatus 100 is displayed. When the user selects the button BT3, a selection field BX3 is displayed on the operation status screen SC4. The user selects "Hide" from the selection field BX3 of the molding apparatus 100 to be deselected. Here, it is assumed that the user selects "Hide" in the selection field BX3 of the molding apparatus A6. When "Hide" is selected, the terminal device 400 transmits to the cloud server 300 information indicating that "Hide" has been selected in the selection field BX3 of the specific molding apparatus 100. The reception unit 320 of the cloud server 300 receives the above-mentioned information and accepts cancellation of the selection of the molding apparatus 100 from the user. The third processing unit 301 of the cloud server 300 transmits to the terminal device 400 data of the operation status screen SC4 in which the molding apparatus 100 for which "Hide" has been selected is not displayed. The fourth processing unit 410 of the terminal device 400 causes the second display unit 440 to display an operation status screen SC4 as shown in FIG. 9, in which the molding apparatus 100 for which "hide" has been selected is not displayed.

[0043] Next, a process of accepting the selection of the molding apparatus 100 from the user will be described with reference to FIG. 10 and FIG. 11. The name of the molding apparatus 100 selected by the user is displayed on the operation status screen SC4 shown in FIG. 10. A selection field BX4 is provided so as to be displayable on the operation status screen SC4. The selection field BX4 is displayed on the operation status screen SC4 when the user selects the apparatus list button BT4. The selection field BX4 displays a list of the molding apparatuses 100 installed on the large-item line of the factory, among the molding apparatuses 100 provided in the molding management system 10. The user selects a molding apparatus 100 to be newly selected from the selection field BX4. Here, it is assumed that the user selects the molding apparatus B6 in the selection field BX4. When a specific molding apparatus 100 is selected from the selection field BX4, the terminal apparatus 400 transmits information indicating that the specific molding apparatus 100 has been selected in the selection field BX4 to the cloud server 300. The reception unit 320 of the cloud server 300 accepts the selection of the molding apparatus 100 from the user by receiving the above-mentioned information. The third processing unit 301 of the cloud server 300 transmits data of the operation status screen SC4 on which the molding apparatus 100 selected in the selection field BX4 is displayed to the terminal device 400. The fourth processing unit 410 of the terminal device 400 causes the second display unit 440 to display the operation status screen SC4 on which the molding apparatus 100 selected in the selection field BX4 is displayed, as shown in FIG.

[0044] The operation status screen may display the molding apparatuses 100 arranged on each line of the factory in a grouped manner. The operation status screen is not limited to the operation status screen SC4 shown in Fig. 8 to Fig. 11, and may be the operation status screen SC5 shown in Fig. 12 or the operation status screen SC6 shown in Fig. 13.

[0045] According to the molding management system 10 in the second embodiment described above, the user can select a plurality of molding apparatuses 100 for which production data is to be displayed on the second display unit 440 of the terminal device 400.

[0046] C. Third embodiment: 14 is an explanatory diagram showing a schematic configuration of the molding management system 10 in the third embodiment. In the third embodiment, the molding management system 10 further includes a sensor 500. The sensor 500 is configured to be able to communicate with the management server 200 via the network NT. The sensor 500 is attached to the first molding device 101. The sensor 500 may be attached to the second molding device 102, or may be attached to both the first molding device 101 and the second molding device 102.

[0047] 15 is an explanatory diagram showing a schematic configuration of a sensor 500. The sensor 500 is a pressure sensor, a strain sensor, a temperature sensor, etc. The sensor 500 includes a fifth control unit 501, a fifth communication unit 502, and a detection unit 503.

[0048] The fifth control unit 501 is configured by a computer including a fifth processing unit 510 and a fifth storage unit 520. The fifth processing unit 510 includes one or more processors. The fifth processing unit 510 controls the first and fifth operations by executing a program stored in the fifth storage unit 520. The fifth storage unit 520 includes a volatile memory such as a RAM and a non-volatile memory such as a ROM. The fifth communication unit 502 includes a communication circuit for controlling communication with other devices such as the management server 200. The detection unit 503 detects production data of the molding device 100 to which the sensor 500 is attached. In this embodiment, the detection unit 503 detects production data of the first molding device 101. Specifically, the detection unit 503 detects the pressure of the injection unit 114, the amount of distortion of the molding die, the temperature of the molding die, and the like.

[0049] The fifth processing unit 510 includes a second transmission unit 511. The second transmission unit 511 is realized by the fifth processing unit 510 executing a program stored in the fifth storage unit 520. Note that the second transmission unit 511 may be realized by a circuit.

[0050] The second transmission unit 511 transmits the production data detected by the detection unit 503 to the management server 200. The second transmission unit 511 transmits the production data to the management server 200, for example, every time the production of a specific molded product is completed or at predetermined time intervals.

[0051] In the third embodiment, the second acquisition unit 310 of the cloud server 300 acquires the production data transmitted by the second transmission unit 511 of the sensor 500 to the management server 200. That is, the second acquisition unit 310 acquires the production data from the sensor 500 via the management server 200.

[0052] In the third embodiment, the third processing unit 301 of the cloud server 300 further includes a notification unit 330. The notification unit 330 is realized by the third processing unit 301 executing a program stored in the third storage unit 302.

[0053] The notification unit 330 transmits an abnormality notification generated based on the production data acquired by the second acquisition unit 310 to the terminal device 400. The notification unit 330 generates an abnormality notification, for example, when the pressure of the injection unit 114 or the amount of distortion of the molding die exceeds an upper limit of a threshold value or falls below a lower limit of a threshold value. The notification unit 330 transmits the generated abnormality notification to the terminal device 400.

[0054] 16 is a diagram showing an abnormality notification screen SC7 displayed on second display unit 440 of terminal device 400. On abnormality notification screen SC7, the contents of the abnormality notification transmitted from cloud server 300 are displayed.

[0055] According to the molding management system 10 in the third embodiment described above, the second acquisition unit 310 of the cloud server 300 acquires production data from the sensor 500 via the management server 200, and stores the acquired production data in the third storage unit 302 of the cloud server 300. The second display unit 440 of the terminal device 400 displays the production data stored in the third storage unit 302 of the cloud server 300. Therefore, when the type of production data that can be acquired differs depending on the molding device 100, it is possible to suppress the production data displayed on the second display unit 440 of the terminal device 400 from differing depending on the molding device 100. In the following, a case will be described as an example in which the second molding device 102 can acquire data on the pressure of the injection unit 114, but the first molding device 101 cannot acquire data on the pressure of the injection unit 114, and the sensor 500 can acquire data on the pressure of the injection unit 114 of the first molding device 101. In this case, the data of the pressure of the injection section 114 of the first molding device 101 is not stored in the first storage section 130 of the first molding device 101. Therefore, the pressure of the injection section 114 is displayed on the first display section 115 of the second molding device 102, but the pressure of the injection section 114 is not displayed on the first display section 115 of the first molding device 101. However, since the data of the pressure of the injection section 114 of the first molding device 101 and the second molding device 102 is stored in the third storage section 302 of the cloud server 300, the data of the pressure of the injection section 114 of the first molding device 101 and the second molding device 102 can be displayed on the second display section 440 of the terminal device 400. In this manner, when the type of data that can be acquired differs depending on the molding device 100, it is possible to suppress the data displayed on the second display section 440 from differing depending on the molding device 100.

[0056] In this embodiment, the notification unit 330 transmits an abnormality notification to the terminal device 400. Therefore, the user can confirm on the terminal device 400 that an abnormality has occurred in the molding apparatus 100.

[0057] D. Fourth embodiment: 17 is an explanatory diagram showing a schematic configuration of a terminal device 400 in the fourth embodiment. In the fourth embodiment, the terminal device 400 further includes a reading unit 460. The configurations of the components of the molding management system 10 other than the terminal device 400 are the same as those in the first embodiment.

[0058] The reading unit 460 reads a code such as a two-dimensional code or a barcode having information for identifying the molding apparatus 100, which is displayed on the housing of the molding apparatus 100. The reading unit 460 is, for example, a camera. The reading unit 460 may be capable of reading an NFC tag provided in the molding apparatus 100 and used for near field communication (NFC).

[0059] In step S20 of the display setting process shown in FIG. 5, the user has the terminal device 400 read the code of the molding device 100 to be selected. The fourth processing unit 410 of the terminal device 400 acquires information for identifying the molding device 100 from the code read by the reading unit 460. The information for identifying the molding device 100 is, for example, the ID number of the molding device 100. The reception unit 320 accepts the selection of the molding device 100 based on the information for identifying the molding device 100 acquired by the fourth processing unit 410. For example, the reception unit 320 sets the molding device 100 identified by the ID number of the molding device 100 as the selected molding device 100. Note that step S10 is not executed in the fourth embodiment.

[0060] According to the molding management system 10 in the fourth embodiment described above, the second display unit 440 of the terminal device 400 displays the production data of the molding device 100 selected based on the information identifying the molding device 100. Therefore, the user can select the molding device 100 for which the production data is to be displayed on the terminal device 400 by having the terminal device 400 read a code or the like having information identifying the molding device 100.

[0061] E. Other embodiments: (E-1) In the above embodiment, both the first molding device 101 and the second molding device 102 are provided with the deletion unit 123. In contrast, only one of the first molding device 101 and the second molding device 102 may be provided with the deletion unit 123.

[0062] (E-2) In the above embodiment, the molding apparatus 100 is an injection molding machine. However, the molding apparatus 100 may be a blow molding machine or a hoop molding machine instead of an injection molding machine.
