For example, a user whose user ID is associated with the access right type of "viewing authority" in a specific record can view the operation data of the molding apparatus 200 included in the record. Also, a user whose user ID is associated with the access right type of "update authority" in a specific record can change the threshold value of the operation data of the molding apparatus 200 included in the record. Here, changing the threshold value of the operation data means, for example, changing the upper limit or lower limit value of the threshold value of the pressure of the injection unit or the temperature of the mold.

[0024] The second processing unit 301 of the cloud server 300 includes an operational data acquisition unit 310, a first identification unit 320, and a data transmission unit 330. The operational data acquisition unit 310, the first identification unit 320, and the data transmission unit 330 are realized by the second processing unit 301 executing a program stored in the second storage unit 302. These may also be realized by circuits.

[0025] The operation data acquisition unit 310 acquires operation data from the multiple molding devices 200 via the management server 100.

[0026] The first identification unit 320 identifies a molding apparatus 200 that is a candidate for which operation data is displayed on the terminal device 400 used by the user, based on the second data. The molding apparatus 200 that is a candidate for which operation data is displayed on the terminal device 400 used by the user is a molding apparatus 200 that is related to the user. Specifically, the above-mentioned molding apparatus 200 is a molding apparatus 200 whose identification information is stored in the second data storage unit 360 in association with the identification information of the user who uses the terminal device 400.

[0030] FIG. 5 is a diagram for explaining an example of the third data. As shown in FIG. 5, the third data storage unit 450 stores a plurality of records in which the device ID and the display necessity information are associated as the third data. In the third data, the display necessity information of the molding device 200 with high relevance to the user is set to "display", and the display necessity information of the molding device 200 with low relevance to the user is set to "non-display". The molding device 200 with high relevance to the user is, for example, the molding device 200 that the user is in charge of. The molding device 200 with low relevance to the user is, for example, the molding device 200 that the user is not in charge of but needs to share information with when an abnormality occurs. For example, when the user is in charge of the molding device 200 of the housing molding line, the molding device 200 that needs to share information with when an abnormality occurs is a molding device 200 of the chassis molding line or the like located on the same floor.

[0031] The terminal device processing unit 401 includes a second identification unit 410 and a terminal device transmission unit 420. The second identification unit 410 and the terminal device transmission unit 420 are realized by the terminal device processing unit 401 executing a program stored in the terminal device storage unit 402.

[0032] The second identifying unit 410 identifies, based on the third data, the molding apparatus 200 whose operation data will be displayed on the display unit 404. The second identifying unit 410 identifies the molding apparatus 200 whose display necessity information is set to "display" in the third data as the molding apparatus 200 whose operation data will be displayed on the display unit 404.

[0033] The terminal device transmission unit 420 transmits the operation data and a request for disclosure of information on the molding device 200 to the cloud server 300 .

[0034] A user logs in to the server using the terminal device 400. The user accesses the server, for example, by starting a web browser on the terminal device 400 and entering a URL. When the server 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 entered by the user on the login screen to the server. If the received user ID and password match a pre-registered user ID and password, the server 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 display unit 404. In the following, it is assumed that the user's login to the server is authenticated.

[0035] 6 is a diagram showing the menu screen SC1. The menu screen SC1 is provided with an operational data display button BT1 and a device display setting button BT2.

[0036] 7 is a process diagram of the operation data display process executed by the molding management system 10.

The operation data display process is executed when the user selects the operation data display button BT1 on the menu screen SC1.

[0037] In step S10, the second identifying unit 410 identifies, based on the third data, molding apparatuses 200 that are candidates for which operation data will be displayed on the display unit 404. Hereinafter, the molding apparatuses 200 that are candidates for which operation data will be displayed on the display unit 404 are also referred to as display candidate molding apparatuses 200. Specifically, the second identifying unit 410 identifies, as display candidates, molding apparatuses 200 for which the display necessity information is set to "display" in the third data.

[0038] In step S20, the terminal device transmission unit 420 generates a first request, which is a request for information disclosure of operation data of the molding apparatus 200 identified as a display candidate in step S10, and transmits the first request to the cloud server 300. That is, the terminal device transmission unit 420 transmits an information disclosure request for operation data of the molding apparatus 200 that is highly relevant to the user to the cloud server 300. The first request includes identification information of the user who is logged in to the server via the terminal device 400 that transmits the first request.

[0039] Step S30 is executed when the cloud server 300 receives the first request transmitted from the terminal device 400. In step S30, the second processing unit 301 acquires, from the fourth data, the access right type associated with the identification information of the molding device 200 and the user included in the first request.

[0040] In step S40, the operation data acquisition unit 310 acquires the operation data of the molding apparatus 200 that is stored in the first data storage unit 350 and is included in the first request.

[0041] In step S50, the data transmission unit 330 associates the identification information of the molding device 200 included in the first request with the access right type acquired in step S30 and the operational data acquired in step S40, and transmits them to the terminal device 400 that sent the first request in step S20.

[0042] Step S60 is executed when the terminal device 400 receives the identification information, the access right type, and the operation data of the molding apparatus 200 transmitted from the cloud server 300. In step S60, the terminal device processing unit 401 causes the display unit 404 to display an operation data screen SC2, on which the operation data received from the cloud server 300 is displayed, based on the access right type.

[0043] 8 is a diagram showing an example of an operation data screen SC2 that displays operation data of a molding apparatus 200 associated with the access right type of "update authority" from among the operation data received by the terminal apparatus 400.

A threshold setting button BT4 is provided on the operation data screen SC3. The threshold setting button BT4 is also called an operation unit. The configuration of the operation data screen SC3 other than the threshold setting button BT4 is the same as that of the operation data screen SC2. The threshold setting button BT4 is grayed out and provided on the operation data screen SC3 so that the user cannot click the threshold setting button BT4. That is, the operation of the threshold setting button BT4 by the user is restricted. Therefore, the user cannot change the threshold of the temperature or pressure of the injection unit of the molding apparatus 200 displayed on the operation data screen SC3. As described with reference to FIG. 8 and FIG. 9, the operation unit is provided on the operation data screen so that the restrictions on the user's operation differ depending on the access right type. In addition, the operation unit is provided on the operation data screen so that the display state differs depending on the access right type.

[0047] 10 is a process diagram showing the device display setting process executed by the molding management system 10. The device display setting process is a process for setting the molding device 200 for displaying operation data on the display unit 404. The device display setting process is executed when the user selects the device display setting button BT2 on the menu screen SC1. The device display setting process is preferably executed when the second data stored in the second data storage unit 360 of the cloud server 300 is updated.

[0048] In step S110, the terminal device transmission unit 420 generates a second request, which is a request to disclose information about the molding device 200 related to the user who uses the terminal device 400, and transmits the second request to the cloud server 300. The second request is also called a distribution destination record disclosure request. The second request includes identification information of the user who is logged in to the server via the terminal device 400 that transmits the second request.

[0049] Step 120 is executed when the cloud server 300 receives a second request transmitted from the terminal device 400. In step S120, the second processing unit 301 acquires, from the second data, the identification information of the forming device 200 associated with the identification information of the user included in the second request. That is, the second processing unit 301 acquires information about the forming device 200 identified by the first identification unit 320 as a display candidate on the terminal device 400 that transmitted the second request.

[0050] In step S130, the data transmitting unit 330 transmits the identification information of the molding apparatus 200 acquired in step S120 to the terminal device 400 that transmitted the second request. That is, the data transmitting unit 330 transmits information on the molding apparatus 200 identified by the first identifying unit 320 to the terminal device 400 that transmitted the second request.

[0051] Step S140 is executed when the terminal device 400 receives the identification information of the molding device 200 transmitted from the cloud server 300. In step S140, the terminal device processing unit 401 determines whether the received identification information of the molding device 200 is included in the third data. If it is determined that the identification information of the molding device 200 is not included in the third data, step S150 is executed. If it is determined that the identification information of the molding device 200 is included in the third data, step S160 is executed.

[0052] In step S150, the second identification unit 410 adds to the third data a record associating the identification information of the molding apparatus 200 not included in the third data among the identification information of the molding apparatus 200 received by the terminal device 400 with the display necessity information. At this time, the second identification unit 410 sets the display necessity information to "display" and adds it to the third data.

[0053] In step S160, the terminal device processing unit 401 judges whether or not the identification information of the molding device 200 included in the third data is included in the identification information of the molding device 200 received by the terminal device 400. If it is judged that the identification information of the molding device 200 included in the third data is not included in the identification information of the molding device 200 received by the terminal device 400, step S170 is executed. If it is judged that the identification information of the molding device 200 included in the third data is included in the identification information of the molding device 200 received by the terminal device 400, step S180 is executed.

[0054] In step S170, the second identification unit 410 deletes from the third data, among the identification information of the molding apparatus 200 included in the third data, the identification information of the molding apparatus 200 that is not included in the identification information of the molding apparatus 200 received by the terminal device 400. As described in steps S150 and S170, the second identification unit 410 matches the identification information of the molding apparatus 200 included in the third data with the identification information of the molding apparatus 200 received by the terminal device 400.

[0055] In step S180, the terminal apparatus processing unit 401 causes the display unit 404 to display an apparatus display setting screen SC4, which is a screen for setting the molding apparatus 200 on which the operation data is displayed, based on the third data.

The apparatus ID of the molding apparatus 200 included in the third data is displayed on the apparatus display setting screen SC4. The apparatus display setting screen SC4 has a check box C1 and a check box C2 for setting display necessity information for each molding apparatus 200. If the display necessity information is "display", a check is input into the check box C1, and if the display necessity information is "non-display", a check is input into the check box C2. A check corresponding to the display necessity information stored as the third data is input into the check box of each molding apparatus 200.

[0057] In step S190 of Fig. 10, the terminal device processing unit 401 accepts a user's operation on the device display setting screen SC4. The user checks the check boxes corresponding to each molding device 200 so that the display necessity information of the molding device 200 that is highly relevant to the user is set to "display" and the display necessity information of the molding device 200 that is less relevant to the user is set to "hide", and clicks the save button BT5. For example, the user checks the corresponding check box so that the display necessity information of the molding device 200 in which an abnormality has occurred, among the molding devices 200 located on the same floor as the molding device 200 that the user is in charge of, is set to "display".

[0058] In step S200, the second identification unit 410 updates the third data based on the operation performed in step S190. Specifically, the second identification unit 410 stores, for the molding apparatus 200 whose display necessity information has been changed on the apparatus display setting screen SC4, a record associating the identification information of the molding apparatus 200 with the changed display necessity information in the third data storage unit 450. The apparatus display setting process is executed as described above.

[0059] According to the molding management system 10 in the first embodiment described above, the terminal device transmission unit 420 transmits to the cloud server 300 a first request, which is a request for information disclosure of the operation data of the molding device 200 identified by the second identification unit 410. The molding device 200 identified by the second identification unit 410 is a molding device 200 whose display necessity information is set to "display" in the third data, that is, a molding device 200 that is highly relevant to the user. When the cloud server 300 receives the first request, it transmits the operation data of the molding device 200 included in the first request to the terminal device 400. The terminal device 400 displays the operation data transmitted from the cloud server 300 on the display unit 404. Therefore, the display unit 404 displays the operation data of the molding device 200 that is highly relevant to the user, but does not display the operation data of the molding device 200 that is less relevant to the user. Therefore, it is possible to reduce the possibility that the user will overlook the operation data of the molding device 200 that is highly relevant to the user.

[0060] As described above, the terminal device transmitting unit 420 transmits to the cloud server 300 an information disclosure request for the operation data of the molding apparatus 200 identified by the second identifying unit 410. Therefore, compared to the case where the terminal device transmitting unit 420 transmits to the cloud server 300 an information disclosure request for the operation data of all the molding apparatuses 200, it is possible to reduce the load on the second processing unit 301 of the cloud server 300 when executing the process of acquiring, in the fourth data, the identification information of the molding apparatus 200 and the access right type associated with the identification information of the user included in the information disclosure request.

[0061] Furthermore, in this embodiment, the terminal device processing unit 401 causes the display unit 404 to display the operation data screen SC2 based on the access right type. Specifically, the terminal device processing unit 401 causes the display unit 404 to display an operation data screen having an operation unit with different restrictions on user operations depending on the access right type. Therefore, for example, only a user having an access right type of "update authority" can change the threshold value of the operation data of the molding apparatus 200. Furthermore, the display state of the operation unit on the operation data screen differs depending on the access right type. Therefore, it is possible for a user to easily recognize his / her own access right type to the molding apparatus 200 whose operation data is displayed on the operation data screen.

[0062] In addition, in this embodiment, the second identification unit 410 updates the third data based on the operation performed on the device display setting screen SC4. Therefore, the user can set the molding device 200 that is highly relevant to the user on the terminal device 400 side. Generally, in the molding management system 10 in which the operation data of a plurality of molding devices 200 is transmitted from the server to the terminal device 400, the system administrator changes the second data to change the setting of the molding device 200 whose operation data is transmitted to the user, that is, the molding device 200 whose operation data is displayed on the user's terminal device 400. In this case, for example, when an abnormality occurs in the molding device 200 or when the relationship between the user and the molding device 200 changes due to the user's relocation in the factory, the system administrator needs to change the second data. In this embodiment, the user can set the molding device 200 that is highly relevant to the user on the terminal device 400 side, so that the burden on the system administrator can be reduced compared to the above-mentioned case.

[0063] B. Second embodiment: 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, the operation data display process is not executed. In the second embodiment, the second storage unit 302 of the cloud server 300 does not need to include the fourth data storage unit 370.

[0064] 12 is a process diagram of the historical data distribution process executed by the cloud server 300. The historical data distribution process is a process in which the cloud server 300 transmits historical data to the terminal device 400 on a regular basis.

[0065] In step S310, the second processing unit 301 of the cloud server 300 determines whether or not a predetermined time has elapsed since the cloud server 300 transmitted the operational data to the terminal device 400. If the cloud server 300 has never transmitted operational data to the terminal device 400, the second processing unit 301 determines that the predetermined time has elapsed. In this embodiment, the predetermined time is a fixed time such as one or two minutes. If it is determined that the predetermined time has elapsed, step S320 is executed. If it is determined that the predetermined time has not elapsed, step S310 is repeatedly executed.

[0066] In step S320, second processing unit 301 acquires operation data of molding apparatus 200 from the first data.

[0067] In step S330, the second processing unit 301 acquires, from the second data, the identification information of the user associated with the identification information of the molding apparatus 200 whose operation data was acquired in step S320. Also, in step S330, the first identification unit 320 identifies, based on the second data, the molding apparatus 200 that is a display candidate on the terminal device 400 used by the user.

[0068] In step S340, the data transmission unit 330 transmits operation data of the molding device 200 associated with the user's identification information in the second data to the terminal device 400 used by the user whose identification information was obtained in step S330. In other words, the data transmission unit 330 transmits the operation data of the molding device 200 identified by the first identification unit 320 in step S330 to the terminal device 400 of the corresponding user. At this time, the data transmission unit 330 transmits the operation data to the terminal device 400 of the user who is logged in to the server. Note that, if the user and the terminal device 400 are associated in advance, the data transmission unit 330 may transmit the operation data to the terminal device 400 regardless of the user's login status. The operation data transmitted to the terminal device 400 is stored in the terminal device storage unit 402.

[0069] In step S350, the second processing unit 301 determines whether or not the user has performed an operation to interrupt the operational data distribution process. If an interruption operation has been performed, the second processing unit 301 ends the operational data distribution process. If an interruption operation has not been performed, the second processing unit 301 returns the process to step S310. That is, until an interruption operation is performed, the data transmission unit 330 transmits the operational data to the terminal device 400 at predetermined time intervals. The operational data distribution process is executed as described above.

[0070] Fig. 13 is a process diagram of the operational status display process executed by the terminal device 400. The operational status display process is a process for displaying operational data on the display unit 404. The operational status display process is executed when the operational status display button BT6 on the menu screen SC5 in the second embodiment shown in Fig. 14 is selected. The operational status display process may be executed in parallel with the operational data distribution process.

[0071] In step S410 in FIG. 13, the terminal device processing unit 401 reads out the operational data that has been transmitted from the cloud server 300 in the operational data distribution process and stored in the terminal device storage unit 402.

[0072] In step S420, the terminal device processing unit 401 determines whether the display necessity information in the third data is set to "display" for each molding apparatus 200 whose operation data was read in step S410. In other words, the terminal device processing unit 401 determines whether the molding apparatus 200 whose operation data was read in step S410 is the molding apparatus 200 identified by the second identification unit 410.

[0073] In step S430, the terminal device processing unit 401 causes the display unit 404 to display the operation status display screen SC6 displaying the operation data of the molding apparatus 200 determined in step S420 to have the display necessity information set to "display." That is, the terminal device processing unit 401 causes the display unit 404 to display the operation status display screen SC6 displaying the operation data of the molding apparatus 200 identified by the second identification unit 410.

[0074] FIG. 15 is a diagram showing an operation status display screen SC6. An apparatus selection field BX1 is provided on the operation status display screen SC6. A graph showing the change in temperature and pressure of the injection section of one molding apparatus 200 whose apparatus ID is selected in the apparatus selection field BX1 is displayed on the operation status display screen SC6. Note that the operation data of a plurality of molding apparatuses 200 may be displayed on the operation status display screen SC6. In this case, the apparatus selection field BX1 does not need to be provided on the operation status display screen SC6. The operation status display process is executed as described above.

[0075] According to the molding management system 10 in the second embodiment described above, the terminal device processing unit 401 displays on the display unit 404 the operation data of the molding apparatus 200 whose display necessity information is set to "display" in the third data among the operation data transmitted from the cloud server 300, that is, the operation data of the molding apparatus 200 identified by the second identification unit 410. Therefore, the display unit 404 displays the operation data of the molding apparatus 200 that is highly relevant to the user, but does not display the operation data of the molding apparatus 200 that is less relevant to the user. Therefore, it is possible to reduce the possibility that the user will overlook the operation data of the molding apparatus 200 that is highly relevant to the user.

[0076] Furthermore, in this embodiment, the data transmission unit 330 of the cloud server 300 transmits the operation data to the terminal device 400 at predetermined time intervals. Therefore, compared to the case where the data transmission unit 330 transmits the operation data collectively to the terminal device 400, the communication load of the cloud server 300 can be averaged regardless of time.

[0077] C. Third embodiment: Fig. 16 is an explanatory diagram showing a schematic configuration of the molding management system 10 in the third embodiment. In the third embodiment, a server, not a terminal device 400, includes a second identification unit 410 and a third data storage unit 450. As shown in Fig. 16, in this embodiment, the second processing unit 301 of the cloud server 300 includes the second identification unit 410, and the second storage unit 302 includes the third data storage unit 450. The configurations of the components of the molding management system 10 other than the second identification unit 410 and the third data storage unit 450 are the same as those in the first and second embodiments.

[0078] In the third embodiment, the third data storage unit 450 stores, as the third data, for each user, identification information of the molding apparatus 200 that is a display candidate on the terminal device 400 used by each user, and its display necessity information in association with each other. Furthermore, the data transmission unit 330 transmits to the terminal device 400 of each user the operation data of the molding apparatus 200 whose display necessity information is set to "display" in the third data, that is, the operation data of the molding apparatus 200 identified by the second identification unit 410.

[0079] According to the molding management system 10 in the third embodiment described above, the data transmission unit 330 can transmit to the terminal device 400 only the operation data of the molding device 200, the operation data of which is displayed on the display unit 404 of the terminal device 400 used by the user.

[0080] D. Other embodiments: (D-1) In the device display setting process shown in Fig. 10, steps S110 to S170 may not be executed. That is, the terminal device processing unit 401 may display the device display setting screen SC4 on the display unit 404 based on the third data previously stored in the third data storage unit 450.

[0081] (D-2) In the second embodiment, the data transmission unit 330 transmits the operational data to the terminal device 400 at predetermined time intervals. However, the data transmission unit 330 may transmit the operational data to the terminal device 400 at any time intervals.
