Figure 1 Fig. 6 is a diagram showing a display screen of the injection molding management apparatus according to the present disclosure. Figures 2 to 12 DETAILED DESCRIPTION

[0026] An embodiment of the present disclosure will be described below with reference to the drawings. Figure 1 Fig. 1 is a diagram showing a structure of a production apparatus equipped with an injection molding management apparatus 1 according to an embodiment of the present disclosure.

[0027] The production apparatus is equipped with a plurality of injection molding machines E, and the injection molding management apparatus 1 according to an embodiment of the present disclosure connected to the plurality of injection molding machines E via a communication network N.

[0028] The injection molding machines E are configured to each have a local control device having a communication interface, and are capable of communicating with the injection molding management apparatus 1. The injection molding machines E not only include an injection molding device main body, but also can include a device that supplies resin, a device that holds a molded product, a device that inspects a molded product, and the like, which are integrally controlled.

[0029] The communication network N can be any network such as a wired LAN such as Ethernet, a wireless LAN such as WiFi, a public communication network such as a portable telephone network, and the like, but a wired LAN is particularly preferable.

[0030] The injection molding management apparatus 1 is equipped with a control device 10 and a display device 20. The control device 10 can be implemented, for example, by causing one or a plurality of computer devices equipped with a CPU, a memory, a communication interface, and the like to read an appropriate program. The display device 20 can be constituted by a liquid crystal monitor or the like, and can be integral with the control device 10.

[0031] The control device 10 has a production information collection section 11, an object information extraction section 12, an information display section 13, and a selection display section 14. These constituent elements are obtained by classifying the functions of the control device 10, and can not be clearly distinguishable in terms of mechanical structure and program structure. In addition, the control device 10 can have more constituent elements that implement other functions.

[0032] ​​The production information collecting section 11 collects production information from a plurality of injection molding machines E. As the production information collected from the injection molding machines E, the identification mark of the injection molding machine E, the identification mark of the product produced or the molding condition applied to the product produced, the operation status (status of automatic operation, manual operation, alarm stop, operation suspension, etc.), the number of good products (shot number), the consumed power, etc. can be cited. It is preferable that these production information be collected as information for each time.

[0033] The target information extracting section 12 extracts target information selected from the production information. It is preferable that the target information be selected based on at least either one of the identification mark of the injection molding machine E and the identification mark of the product produced or the molding condition by the injection molding E. That is, it is preferable that the search formula for extracting the target information be a search formula specifying at least one of the identification mark of the injection molding machine E and the identification mark of the product (molding condition). In addition, for the extraction of the target information, in addition to the setting of at least one of the identification mark of the injection molding machine E and the identification mark of the product (molding condition), etc., other search conditions can be set.

[0034] Specifically, the target information can also be a plurality of time series data on the operation status, the number of good products, the consumed power, etc. of a single injection molding machine E, or a plurality of time series data on the operation status, the number of good products, the consumed power, etc. of a single product (molding condition), or time series data on only the operation status of a group composed of a plurality of injection molding machines E, or data on only the current operation status, the number of good products, the consumed power, etc. of all of the injection molding machines E.

[0035] The production information to be confirmed differs depending on the management object and the management purpose of the user, and it is inefficient to provide all of the production information to all of the users. Therefore, it is preferable that the target information be set as information obtained by grouping the production information which is efficient for the user to confirm at one time, and different target information can be set depending on the attribute of the user, such as the category of the operator, the manager of the production equipment, the equipment maintenance manager, the mold manager, etc. Specifically, in the case of the management of the production equipment as a whole, it is necessary to grasp the operation rate, the operation time, the production quantity, the consumed power, etc. considering the production equipment as a whole. In the case of the maintenance of the injection molding machine E, it is necessary to grasp the operation rate, the operation time of each injection molding machine E. In the case of the production management, it is not necessary to grasp the production quantity of each injection molding machine E, but it is necessary to grasp the production quantity of each product (molding condition).

[0036] The information display section 13 displays the target information in a prescribed display manner on the display device 20. The display manner displayed by the information display section 13 can include at least any one of a list, a chart, and a time chart. As the display manner, for example, a list of the operation status, the number of good products, the consumed power, etc. of each injection molding machine E, a chart of the operation status, the number of good products, the consumed power, etc. of each injection molding machine E, a time chart of the operation status, the number of good products, the consumed power, etc. of each injection molding machine E, a list of the operation status, the number of good products, the consumed power, etc. of each product (molding condition), a chart of the operation status, the number of good products, the consumed power, etc. of each product (molding condition), a time chart of the operation status, the number of good products, the consumed power, etc. of each product (molding condition), a list of the operation status, the number of good products, the consumed power, etc. of all of the injection molding machines E, a chart of the operation status, the number of good products, the consumed power, etc. of all of the injection molding machines E, a time chart of the operation status, the number of good products, the consumed power, etc. of all of the injection molding machines E, etc. can be cited.Figure 2 and Figure 3 As shown in FIG. 10, for example, the list table can also display a plurality of production information by characters (which can include numbers and marks) for a single injection molding machine E or product (molding condition). As shown in FIG. 11, for example, the graph can also be a bar chart, line chart, etc. showing the change in production information represented by numerical values over time for one or a plurality of injection molding machines E or products (molding conditions). As shown in FIG. 12, for example, the time table can also illustrate the transition of the operation state, etc. that cannot be numerically represented at each time for one or a plurality of injection molding machines E. Further, as shown in FIG. 13, for example, the display mode displayed by the information display section 13 can also include a plurality of the list table, graph, and time table. Also, the display mode displayed by the information display section 13 can also include information display other than the list table, graph, and time table. Figures 4 to 7 Figure 8 Figure 9

[0037] Further, the display mode displayed by the information display section 13 can include at least any one of the operation rate, operation time, production quantity (cumulative value of the number of good products), and consumed power amount (cumulative value of the consumed power) calculated from the target information.

[0038] As shown in FIG. 14, for example, the selection display section 14 displays a plurality of operation images G1 to G8 representing the combination of the target information and display mode in a selectable manner on the display device 20. Preferably, the selection display section 14 selectively displays the operation images G1 to G8 representing a part of the combinations of the target information and display mode other than the combinations that are theoretically possible but lack usefulness in presenting to the user, and more preferably, the operation images G1 to G8 displayed in accordance with the attribute of the user determined by, for example, the login ID, selection on the screen, etc. Figures 10 to 13

[0039] Preferably, the operation images G1 to G8 displayed by the selection display section 14 are iconized so that the user can easily recognize the combination of the target information and display mode. Figures 10 to 13 The operation images G1 to G8 illustrated in the example are configured by superimposing an image representing the target information on an image representing the display mode. Further, the operation images G1 to G8 can also contain minimal character information such as an identification mark representing the group of injection molding machines E included in the target information, etc. In the illustrated example, as the image representing the target information, an image representing a single injection molding machine E, an image representing a single product (molding condition), an image representing a plurality of injection molding machines, and an image representing a plurality of products (molding conditions) are used. Further, as the image representing the display mode, an image representing the list table, an image representing the graph, an image representing the time table, and an image representing the combination of the time table and list table are used. ​​​​

[0040] Not only does the production information to be confirmed vary depending on the user's management objectives and purposes, but the optimal way to display this information also differs. For example, if the user is an operator, they value visual clarity and prefer charts to easily identify general trends in order to grasp the overall picture. On the other hand, when determining whether production equipment needs maintenance or implementing improvements to enhance productivity, they sometimes desire a table containing detailed numerical and temporal information.

[0041] As a specific example, when the user is the operator, such as Figure 10 As shown, the selection display unit 14 can also display a first operation image G1, a second operation image G2, and a third operation image G3, which are useful for understanding the overall operating status of the production equipment. The first operation image G1 is used to display the operating status of multiple injection molding machines E per unit time (in the figure, elapsed time) using graphs. Figure 6 The second operation image G2 is used to display the operating status of multiple injection molding machines E respectively using a timetable. Figure 8 The third operation image G3 is used to display the production quantity and operating status of multiple products (or each molding condition) per unit time (in the image, time has elapsed) using charts. Figure 7 )migrate.

[0042] When the user is a production manager, such as Figure 11 As shown, the selection display unit 14 can also display a fourth operation image G4, a fifth operation image G5, and a sixth operation image G6, which are useful for monitoring the production progress. The fourth operation image G4 is used to display a screen showing an overview of the operation information of a single injection molding machine E, the number of qualified products, etc. Figure 2 The fifth operation image G5 is used to display a graph showing the production quantity and operating status of a single injection molding machine E per unit time (in the figure, elapsed time). Figure 4 The sixth operation image G6 is used to migrate to a screen displaying a chart showing the time-series changes in the production quantity and operating status of an individual product (category of molding conditions). Figure 5 )migrate.

[0043] The selection display section 14 can also have a function of selecting the object information to be displayed, that is, the injection molding machine E or the product to be displayed, according to the selection of the operation image G4, according to the frequency of use, the kind of the product, the recent operation state, and the like. As an example, the selection display section 14 can also display production information on the injection molding machine E in which the production quantity of the same product as the product currently being produced is large in a certain period as the object information. In this case, the selection display section 14 can also display the operation image G4 to which character information for specifying the selected object information is added, for example, a plurality of operation images G4 to which character information is added to a plurality of object information in which the production quantity is large, respectively.

[0044] In the case where the user is a maintenance manager of the injection molding machine E, as shown in FIG. 6, the selection display section 14 can also display a seventh operation image G7 for migrating to a screen (G7) for displaying a time chart showing the temporal change of the operation state of a single injection molding machine E and a table showing the operation state at each time, and a second operation image G2 for migrating to a screen (G2) for displaying the operation state of a plurality of injection molding machines E by a time chart, respectively. Figure 12 Figure 9 In the case where the user is a maintenance manager of the injection molding machine E, as shown in FIG. 6, the selection display section 14 can also display a seventh operation image G7 for migrating to a screen (G7) for displaying a time chart showing the temporal change of the operation state of a single injection molding machine E and a table showing the operation state at each time, and a second operation image G2 for migrating to a screen (G2) for displaying the operation state of a plurality of injection molding machines E by a time chart, respectively. Figure 8

[0045] In the case where the user is a maintenance manager of the injection molding machine E, as shown in FIG. 6, the selection display section 14 can also display a seventh operation image G7 for migrating to a screen (G7) for displaying a time chart showing the temporal change of the operation state of a single injection molding machine E and a table showing the operation state at each time, and a second operation image G2 for migrating to a screen (G2) for displaying the operation state of a plurality of injection molding machines E by a time chart, respectively. Figure 13 Figure 3 In the case where the user is a maintenance manager of the injection molding machine E, as shown in FIG. 6, the selection display section 14 can also display a seventh operation image G7 for migrating to a screen (G7) for displaying a time chart showing the temporal change of the operation state of a single injection molding machine E and a table showing the operation state at each time, and a second operation image G2 for migrating to a screen (G2) for displaying the operation state of a plurality of injection molding machines E by a time chart, respectively. Figure 5

[0046] As described above, by the selection display section 14 displaying a plurality of operation images G1 to G8 showing the combination of the object information and the display mode, the user can confirm the necessary information in an easily understandable display mode by a small number of operations. In contrast, in the conventional injection molding management device, it is necessary to specify the display mode and the production information to be displayed as the object in sequence, and thus the work is complicated.

[0047] ​​​​In addition, among the theoretically possible combinations of production information and display modes, there are many combinations that have little value as information. As combinations of production information and display modes that are not needed, an example can be given of a list display of production information about all injection molding machines E. For example, it is thought that the operator needs to grasp the overall picture of manufacturing by the production equipment, but even if all the information is displayed by characters, not only is the amount of information excessive, but also the readability is low, so it is difficult to grasp the overall picture. The same is true for a list display of all products, and it is not suitable for grasping the production progress of individual products, predicting the life of the mold, and the like. In addition, there are cases where the operation frequency of a single molding condition is low, and even if the operation status is displayed by a schedule for a single molding condition or all other molding conditions, only the non-use status becomes conspicuous, and it is not possible to properly grasp the operation time that is needed for life prediction of individual molds, judgment of the inspection timing.

[0048] However, in the injection molding management device 1 of the present embodiment, the selection display part 14 displays only the operation images G1 to G8 that display combinations of production information (target information) needed by the user and display modes, so not only does the operation of the user become easy, but also it is not necessary to have a program for combinations of production information and display modes that are not needed, so it is also possible to simplify the program.

[0049] The above describes an embodiment of the injection molding management device according to the present disclosure, but the scope of the present disclosure is not limited to the above-described embodiment. In addition, the effects described in the above-described embodiment are nothing more than examples of the most preferred effects produced by the injection molding management device according to the present disclosure, and the effects of the injection molding management device according to the present disclosure are not limited to the contents described in the above-described embodiment.

[0050] As an example, the injection molding management device according to the present disclosure can also determine the target information based on attributes other than the injection molding machine and the product (molding condition).
