[0007] A. First embodiment: FIG. 1 is an explanatory diagram showing a schematic configuration of the molding management system 10. The molding management system 10 includes a management server 100, a cloud server 200, and a terminal device 300. The management server 100 is configured to be able to communicate with the molding device 400 and the inspection device 500 via a network NT so as to be able to transmit and receive information to and from these. The network NT may be, for example, a LAN, a WAN, or the Internet. The cloud server 200 is configured to be able to communicate with the management server 100 and the terminal device 300 via the Internet IN so as to be able to transmit and receive information to and from these. Hereinafter, the management server 100 and the cloud server 200 are also collectively referred to as servers. FIG. 1 shows an example in which the management server 100 is configured to be able to communicate with one molding device 400 and one inspection device 500 via the network NT, but the management server 100 may be configured to be able to communicate with multiple molding devices 400 and multiple inspection devices 500 via the network NT. Further, while FIG. 1 shows an example in which the molding management system 10 includes one terminal device 300, the molding management system 10 may include a plurality of terminal devices 300.

[0008] The molding device 400 is a device for molding a molded product. In this embodiment, the molding device 400 is an injection molding machine. The molding device 400 includes a first control unit 401, a clamping unit, and an injection unit, which are not shown. The clamping unit opens and closes a mold having a cavity attached to the clamping unit. The mold may be made of metal, ceramic, or resin. A metal mold is called a metal mold. The injection unit injects a plasticized modeling material into the cavity of the mold. The first control unit 401 is configured by a computer including one or more processors, a storage device, and an input / output interface for inputting and outputting signals to and from the outside. The first control unit 401 may be configured by multiple computers.

[0009] The first control unit 401 controls each unit of the molding device 400 to perform injection molding based on the molding conditions acquired from the cloud server 200 via the management server 100, and molds a molded product. More specifically, the first control unit 401 controls the clamping unit to clamp the mold, and controls the injection unit to inject the modeling material into the cavity of the mold, thereby molding a molded product having a shape corresponding to the shape of the cavity provided in the mold. Hereinafter, the injection of the modeling material into the cavity of the mold is also referred to as a shot.

[0010] The sensor 410 measures the injection pressure, the temperature of the mold, the injection filling time, etc., which are physical quantities related to the operating state of the molding apparatus 400. The sensor 410 is, for example, a pressure sensor that measures the injection pressure, or a temperature sensor that measures the temperature of the mold.

[0011] The first control unit 401 acquires a physical quantity related to the operating state of the molding apparatus 400 from the sensor 410 and transmits it to the management server 100. The sensor 410 may be configured to be able to communicate with the management server 100 via a network NT. In this case, the sensor 410 may transmit the measured physical quantity related to the operating state of the molding apparatus 400 to the management server 100 via the network NT.

[0012] The inspection device 500 is a device that inspects molded products. The inspection device 500 is composed of a second control unit 501 and a camera (not shown). The second control unit 501 controls the camera to capture an image of the molded product, and performs image analysis of the captured molded product to measure the dimensions and inspect the appearance of the molded product. The second control unit 501 measures the dimensions of the molded product, such as the height, overall length, and overall width of the molded product. In addition, the second control unit 501 inspects the molded product for defects, such as scratches and warping, in the appearance inspection. The second control unit 501 judges whether the molded product is defective or not based on the results of the dimensions and appearance inspection for each molded product. The second control unit 501 transmits information on the inspection results of the molded product to the management server 100. Here, the information on the inspection results of the molded product includes the judgment result of whether the molded product is a good product or a defective product, and the type of defect of the molded product. The type of defect of the molded product is, for example, scratches, insufficient filling, burrs, etc. The inspection device 500 may measure the dimensions of the molded product using various displacement sensors or length measuring sensors instead of a camera.

[0013] The management server 100 is configured by a computer including a first processing unit 101, a first storage unit 102, and a first communication unit 103. The first processing unit 101 includes one or more processors. The first processing unit 101 controls the operation of the management server 100 by executing a program stored in the first storage unit 102. The first storage unit 102 includes a main storage unit such as a RAM, and an auxiliary storage unit such as a hard disk drive. The first communication unit 103 includes a communication circuit for controlling communication with other devices such as the cloud server 200, the molding device 400, and the inspection device 500. The management server 100 may be configured by multiple computers.

[0014] First processing unit 101 includes first acquisition unit 110 and first inspection result acquisition unit 120. First acquisition unit 110 and first inspection result acquisition unit 120 are realized by first processing unit 101 executing a program stored in first storage unit 102. These may also be realized by circuits.

[0015] The first acquisition unit 110 acquires the number of shots executed by the molding apparatus 400 from the molding apparatus 400. Hereinafter, the number of shots is also referred to as the shot count.

[0016] The first inspection result acquisition unit 120 acquires information relating to the inspection results of the molded product from the inspection device 500. Hereinafter, the information relating to the inspection results of the molded product will also be simply referred to as the inspection results of the molded product.

[0017] Cloud server 200 is a server used via the Internet IN. Cloud server 200 includes a second processing unit 201, a second storage unit 202, and a second communication unit 203. The first storage unit 102 of management server 100 and the second storage unit 202 of cloud server 200 are also collectively referred to as a storage unit. Note that management server 100 and cloud server 200 may be configured as a single server.

[0018] The second storage unit 202 includes a first data storage unit 250, a second data storage unit 260, a third data storage unit 270, and a fourth data storage unit 280.

[0019] The first data storage unit 250 stores a specified completion number, which is the number of molded products per lot. The specified completion number is a number that is determined in advance by the user. In this specification, a lot means a unit such as a box or a bag. For example, the existence of five lots of a specific molded product means the existence of five boxes or bags containing the specific molded product.

[0020] The second data storage unit 260 stores a specified lot number, which is the number of lots included in one production lot of molded products. The specified lot number is a number that is determined in advance by the user. In this specification, a production lot means a collection of molded products produced on a daily basis or by a molding device. For example, one production lot is composed of a lot of molded products produced on a specific day. One production lot includes multiple lots.

[0021] Third data storage unit 270 stores the number of cavities that the casting mold has.

[0022] The fourth data storage unit 280 stores information on the production performance of a lot. The information on the production performance of a lot includes the production status of the lot and the number of stocks. Here, the production status of a lot is one of "on standby", "in process", and "completed". "On standby" means a state in which the production of the lot has not yet started. In this specification, the production of a lot means the production of molded products that constitute the lot. "In process" means a state in which the production of the lot is currently being carried out. "Completed" means that the production of the lot has been completed. The number of stocks means the number of molded products that constitute one lot and have been completed. For example, if the production of 50 molded products has been completed among the molded products that constitute a lot and the specified number of completion is 100, the number of stocks is 50.

[0023] Second processing unit 201 includes second acquisition unit 210, second inspection result acquisition unit 220, production number calculation unit 230, and lot completion unit 240. Second acquisition unit 210, second inspection result acquisition unit 220, production number calculation unit 230, and lot completion unit 240 are realized by second processing unit 201 executing a program stored in second storage unit 202. These may also be realized by circuits.

[0024] The second acquisition unit 210 acquires the number of shots acquired by the first acquisition unit 110 of the management server 100 from the management server 100 .

[0025] The second inspection result acquisition section 220 acquires, from the management server 100, information relating to the inspection results of the molded product acquired by the first inspection result acquisition section 120 of the management server 100.

[0026] The production number calculation unit 230 calculates the production number of molded products using the number of shots acquired by the second acquisition unit 210, information regarding the inspection results of the molded products acquired by the second inspection result acquisition unit 220, and the number of cavities stored in the third data storage unit 270.

[0027] When the production number calculated by the production number calculation unit 230 reaches the specified completion number stored in the first data storage unit 250, the lot completion unit 240 stores in the fourth data storage unit 280 that the production of one lot has been completed, and stores in the fourth data storage unit 280 that the production of one lot different from the lot whose production has been completed has started. The lot completion unit 240 repeatedly executes the above-mentioned process until the number of lots whose production has been completed reaches the specified lot number stored in the second data storage unit 260.

[0028] The terminal device 300 is configured as a computer including a terminal device processing unit 301, a terminal device storage unit 302, a terminal device communication unit 303, a display unit 304, and an input unit 305. The terminal device 300 is, for example, a notebook computer, a tablet terminal, a smartphone, a handheld terminal, or the like. The terminal device processing unit 301 includes one or more processors. The terminal device processing unit 301 controls the operation of the terminal device 300 by executing a program stored in the terminal device storage unit 302. The terminal device storage unit 302 is configured by a main storage device such as a RAM and an auxiliary storage device such as a hard disk drive. The terminal device communication unit 303 controls communication with other devices such as the cloud server 200. The display unit 304 displays various screens. The display unit 304 is configured by, for example, a liquid crystal display. The input unit 305 accepts input from a user. The input unit 305 is configured by, for example, a mouse and a keyboard. The display unit 304 and the input unit 305 may be integrated as a touch panel.

[0029] A user accesses the server using the terminal device 300. For example, the user accesses the cloud server 200 by starting a web browser on the terminal device 300 and inputting a URL.

[0030] 2 and 3 are diagrams for explaining the sequence of the manufacturing lot production process executed by the molding management system 10. The manufacturing lot production process is a process for producing molded products that constitute all of the lots included in one manufacturing lot. In this specification, producing a lot included in a manufacturing lot, i.e., producing molded products that constitute a lot included in a manufacturing lot, is also called producing a manufacturing lot. The sequence shown in FIG. 2 and the sequence shown in FIG. 3 are executed consecutively. After step S110 shown in FIG. 2, step S120 shown in FIG. 3 is executed.

[0031] In step S10, the terminal device 300 accepts the start of a production lot. Step S10 is executed when a predetermined operation is performed on the terminal device 300. Step S10 is executed, for example, when a user selects a production lot for which production is to be started from a list of production lots displayed on the display unit 304 of the terminal device 300. The terminal device 300 accepts information indicating that production of the production lot selected by the user is to be started.

[0032] In step S20, the terminal device 300 notifies the cloud server 200 of information indicating that production of the manufacturing lot accepted in step S10 is to be started.

[0033] In step S30, the cloud server 200 processes the start of the production lot. The second processing unit 201 of the cloud server 200 processes the start of the production lot, for example, by storing in the second storage unit 202 information indicating the start of production of the production lot notified from the terminal device 300 in step S20.

[0034] In step S40, cloud server 200 processes the start of one lot included in the production lot for which start processing was performed in step S30. Second processing unit 201 of cloud server 200 stores in fourth data storage unit 280 the fact that production of one lot included in the production lot for which start processing was performed in step S30 has started. Here, the lot for which second processing unit 201 of cloud server 200 performs start processing is a lot whose production status stored in fourth data storage unit 280 is "on hold". Second processing unit 201 of cloud server 200 changes the production status of the one lot for which production has started from "on hold" to "in process".

[0035] In step S50, the cloud server 200 notifies the management server 100 of information to the effect that production of one lot, the start processing of which was performed in step S40, is to commence.

[0036] In step S60, management server 100 acquires the information notified from cloud server 200 in step S50, thereby recognizing the start of one lot.

[0037] In step S70, the management server 100 notifies the molding apparatus 400 of the start of one lot that was started in step S40. For example, the management server 100 transmits a signal to the molding apparatus 400 to start production of one lot that was started in step S40. When the molding apparatus 400 receives the above-mentioned signal, it starts production of the molded products that make up that lot.

[0038] In step S80, the molding apparatus 400 notifies the management server 100 of the number of shots that have been executed. The molding apparatus 400 may notify the management server 100 that a shot has been executed each time a shot is executed, or may notify the management server 100 of the number of shots that have been executed at predetermined time intervals.

[0039] In step S90, the first acquisition unit 110 of the management server 100 acquires the number of shots notified from the molding apparatus 400 in step S80.

[0040] In step S100, the management server 100 notifies the cloud server 200 of the number of shots acquired by the first acquisition unit 110 in step S90.

[0041] In step S110, second acquisition unit 210 of cloud server 200 acquires the number of shots notified from management server 100 in step S100.

[0042] 3, the inspection device 500 notifies the management server 100 of the inspection results of the molded products. When defects are detected in the molded products, the inspection device 500 notifies the management server 100 of the number of defective products and the type of the defects in the molded products. The inspection device 500 may also notify the management server 100 of the number of defective products and the number of non-defective products of the molded products produced by the molding device 400.

[0043] In step S130, the first inspection result acquisition unit 120 of the management server 100 acquires the inspection results of the molded product notified from the inspection device 500 in step S120.

[0044] In step S140, the management server 100 notifies the cloud server 200 of the inspection results of the molded product acquired by the first inspection result acquisition unit 120 in step S130.

[0045] In step S150, the second inspection result acquisition unit 220 of the cloud server 200 acquires the inspection results of the molded product notified in step S140 from the management server 100. Note that steps S80 to S110 and steps S120 to S150 may be executed in parallel.

[0046] In step S160, the cloud server 200 executes a lot completion process.

[0047] 4 is a process diagram of the lot completion process. First, in step S310, the production number calculation unit 230 calculates the production number of molded products using the number of shots acquired by the second acquisition unit 210 in step S110 of FIG. 2, the inspection results of the molded products acquired by the second inspection result acquisition unit 220 in step S150 of FIG. 3, and the number of cavities stored in the third data storage unit 270. In this embodiment, the production number of molded products means the number of good products among the produced molded products. The production number calculation unit 230 calculates the production number of molded products by subtracting the number of defective products from the value obtained by accumulating the number of shots and the number of cavities.

[0048] In step S320, the second processing unit 201 of the cloud server 200 determines whether the production quantity calculated in step S310 has reached the specified completion quantity stored in the first data storage unit 250. If the production quantity has reached the specified completion quantity, the second processing unit 201 executes step S330. If the production quantity has not reached the specified completion quantity, the second processing unit 201 returns the process to step S80 in FIG. 2.

[0049] In step S330, the lot completion unit 240 processes the completion of one lot. The lot completion unit 240 stores the completion of the production of one lot in the fourth data storage unit 280. The lot completion unit 240 changes the production status of the lot whose production has been completed, which is stored in the fourth data storage unit 280, from "in process" to "completed."

[0050] In step S340, the second processing unit 201 determines whether or not the number of lots whose production has been completed has reached the specified lot number stored in the second data storage unit 260. If the number of lots whose production has been completed has reached the specified lot number, the second processing unit 201 ends the lot completion process. If the number of lots whose production has been completed has not reached the specified lot number, the second processing unit 201 returns the process to step S40 in Fig. 2. In step S40, which is executed for the second or subsequent times, the second processing unit 201 stores in the fourth data storage unit 280 that production of one lot different from the lot whose production has been completed in step S330 has started.

[0051] 3, the terminal device 300 accepts the completion of the production lot. Step S170 is executed when a predetermined operation is performed on the terminal device 300. For example, the terminal device 300 accepts the completion of the production lot when a user inputs, to the terminal device 300, information that the production of the production lot selected in step S10 has been completed.

[0052] In step S180, the terminal device 300 notifies the cloud server 200 of information that the production of the manufacturing lot accepted in step S170 has been completed.

[0053] In step S190, the cloud server 200 processes the completion of the production lot. The second processing unit 201 of the cloud server 200 processes the completion of the production lot, for example, by storing information indicating that the production of the production lot has been completed, notified from the terminal device 300 in step S180, in the second storage unit 202. The production lot production process is executed as described above.

[0054] 5 is a diagram showing a lot list screen SC1 displayed on the display unit 304 of the terminal device 300 during the period in which steps S40 to S160 of the manufacturing lot production process are executed. The lot list screen SC1 displays a list of lots belonging to the currently produced manufacturing lot. For each lot, the lot list screen SC1 displays the lot ID number, the number of stocks, the item name of the molded product, the process currently being executed, the production status of the lot, etc. That is, the lot list screen SC1 displays information related to the production record of the lot stored in the fourth data storage unit 280.

[0055] 6 is a diagram showing the production performance display screen SC2. The production performance display screen SC2 is displayed on the display unit 304 of the terminal device 300 when the user executes a predetermined operation on the terminal device 300. The production performance display screen SC2 displays, for each production lot, the item name of the molded product, the name of the mold used, the production performance of the molded product, the scheduled completion time of production, the defective rate of the molded product, and the cycle time. The production performance display screen SC2 displays, as the production performance of the molded products, the planned production number of molded products and the number of molded products actually produced. The production performance display screen SC2 also displays the production plan and production performance for each hour in a graph.

[0056] According to the molding management system 10 in the first embodiment described above, the production number calculation unit 230 calculates the production number of molded products using the number of shots, the inspection results of the molded products, and the number of cavities, and when the production number of molded products reaches the specified completion number, the lot completion unit 240 stores the completion of the production of one lot in the fourth data storage unit 280. Therefore, the user does not need to input the production results of the lot of molded products into the system every time the production of one lot is completed. Therefore, the user's work efficiency can be improved.

[0057] In addition, in this embodiment, the production number calculation unit 230 calculates the production number of molded products using the inspection result of the molded products. Therefore, when the number of good products among the produced molded products reaches the completion specified number, the fact that the production of one lot is completed is stored in the fourth data storage unit 280. If the inspection result of the molded products is not used to calculate the production number of molded products, when the number of molded products including not only good products but also defective products reaches the completion specified number, the fact that the production of one lot is completed is stored in the fourth data storage unit 280. Therefore, in the molding management system 10 of this embodiment, it is possible to prevent the fact that the production of a lot is completed from being stored in the fourth data storage unit 280 even if the number of good products has not reached the completion specified number.

[0058] Furthermore, in this embodiment, information on the production record of the lot stored in the fourth data storage unit 280 is displayed on the display unit 304 of the terminal device 300. Therefore, the user can check the progress of the production of the lot using the terminal device 300. For example, when a lot list screen SC1 as shown in Fig. 5 is displayed on the display unit 304, the user can check how many lots have been completed among the lots included in the manufacturing lot currently being produced.

[0059] When a user needs to input the production results of a molded product lot into the system every time the production of one lot is completed, the user may input the completion of the production of multiple lots into the system all at once after the production of multiple lots is completed. In this case, even if the production of a lot is actually completed, the production of the lot is not completed on the system. Therefore, the user cannot accurately grasp the progress of the production of the molded product even if he checks the system. In the molding management system 10 of this embodiment, when the production number of molded products reaches the completion specified number, the lot completion unit 240 stores the completion of the production of one lot in the fourth data storage unit 280, so that the production status of the actual lot and the production status of the lot on the system match. Therefore, the user can accurately grasp the progress of the production of the molded product by checking the system. This allows the user to quickly take measures when the production of the molded product is behind schedule. In addition, it is easy for the user to notice the production of defective products at an early stage.

[0060] B. Second embodiment: 7 is an explanatory diagram showing a schematic configuration of the molding management system 10 in the second embodiment. In the second embodiment, the management server 100 is configured to be able to communicate with the molding device 400, the inspection device 500, and the data collection device 600 via a network NT so as to be able to transmit and receive information to and from these. The configurations of the components of the molding management system 10 other than the management server 100 are the same as those in the first embodiment.

[0061] In the second embodiment, the molding apparatus 400 transmits data related to the molding of the molded product to the data collecting apparatus 600. Specifically, the molding apparatus 400 transmits the number of executed shots to the data collecting apparatus 600. The molding apparatus 400 may transmit physical quantities related to the operating state of the molding apparatus 400 acquired from the sensor 410 to the data collecting apparatus 600.

[0062] In the second embodiment, the first acquisition unit 110 of the management server 100 acquires the number of shots performed by the molding apparatus 400 from the data collection apparatus 600.

[0063] Fig. 8 is a process diagram of the manufacturing lot production process in the second embodiment. Note that the same parts as those in the manufacturing lot production process in the first embodiment shown in Fig. 2 are denoted by the same reference numerals and the description thereof is omitted. The process from step S120 onwards is the same as in the first embodiment, so the illustration and description thereof are omitted.

[0064] In step S81, the molding apparatus 400 notifies the data collecting apparatus 600 of the number of executed shots. The molding apparatus 400 may notify the data collecting apparatus 600 of the execution of a shot each time a shot is executed, or may notify the data collecting apparatus 600 of the number of executed shots at predetermined time intervals.

[0065] In step S82, the data collection device 600 notifies the management server 100 of the number of shots notified by the molding device 400 in step S81.
