[0008] The injection molding machine management device manages a plurality of injection molding machines. The plurality of injection molding machines managed by the management device include injection molding machines capable of molding a target molded product and injection molding machines incapable of molding the target molded product. For example, an injection molding machine with a maximum injection pressure lower than the maximum injection pressure required to mold the target molded product cannot mold the target molded product. Therefore, the management device determines for each of the plurality of injection molding machines whether it is a molding-capable machine, i.e., an injection molding machine capable of molding the target molded product.

[0009] However, simply presenting information on whether or not a machine is capable of molding is inconvenient for workers.

[0010] An object of the present disclosure is to provide a convenient injection molding machine management device, an injection molding system, and an injection molding machine management method.

[0011] 1 is a block diagram showing the configuration of an injection molding system 10. The injection molding system 10 has a management device 12, a resin flow analysis device 14, and a plurality of injection molding machines 16.

[0012] The resin flow analysis device 14 generates molding conditions corresponding to each mold based on the analysis of the resin flow in each mold. Since a mold is formed for each molded product, it can be said that the molding conditions are generated corresponding to the molded product.

[0013] The resin flow analysis device 14 acquires molding results corresponding to each mold based on the analysis of the resin flow in each mold. The molding results acquired by the resin flow analysis device 14 are molding results obtained by performing a simulation, but are not limited to this. The molding results acquired by the resin flow analysis device 14 may also include information on the model used in the simulation. Since a mold is acquired for each molded product, it can also be said that the molding results are acquired corresponding to the molded product.

[0014] The management device 12 manages a plurality of injection molding machines 16. The management device 12 determines whether each injection molding machine 16 is capable of molding. A capable injection molding machine is an injection molding machine 16 that can mold a target molded product using a specified mold. This determination is made by comparing the molding results corresponding to the mold used to mold the target molded product with the specifications of each injection molding machine 16.

[0015] The management device 12 determines that the injection molding machine 16 is a machine capable of molding if the specifications of the injection molding machine 16 can achieve the molding results obtained by the resin flow analysis device 14. On the other hand, the management device 12 determines that the injection molding machine 16 is a machine that cannot achieve the molding results obtained by the resin flow analysis device 14.

[0016] The management device 12 displays machine information of each injection molding machine 16 on the display unit 18. The machine information includes, for example, the model name of each injection molding machine 16, the serial number of each injection molding machine 16, the specifications of each injection molding machine 16, the installation location of each injection molding machine 16, the operating status of each injection molding machine 16, the operating schedule of each injection molding machine 16, the type of resin used by the injection molding machine 16, etc.

[0017] Of the above machine information, information on the installation location of each injection molding machine 16 and the operation schedule of each injection molding machine 16 is stored in a memory unit 50 of the management device 12, which will be described later. Of the above machine information, information other than the installation location of each injection molding machine 16 and the operation schedule of each injection molding machine 16 is stored in a memory unit 34 of the injection molding machine 16, which will be described later.

[0018] The management device 12 outputs molding information related to molding of the target molded product to each injection molding machine 16 that has been determined to be a moldable machine. The molding information includes, for example, the molding conditions of the target molded product, the molding schedule of the target molded product, the type of resin used to mold the target molded product, the planned production quantity of the target molded product, etc.

[0076] By looking at the display on the display unit 18 shown in FIG. 10, the worker can easily understand the operation schedule of each molding machine.

[0077] [Method for determining whether a machine is suitable for molding] The molding determination unit 58 determines whether each injection molding machine 16 is suitable for molding by comparing the required values ​​obtained from the analytical molding results generated by the resin flow analysis device 14 corresponding to the mold of the target molded product with the specification information of each injection molding machine 16.

[0078] The required values ​​are compared with the specification information for each item, such as injection pressure, injection rate, injection volume, mold clamping force, mold dimensions, and resin.

[0079] As an example, a method for comparing the required value with the specification information for the injection pressure item will be described. The molding judgment unit 58 obtains the maximum value of the injection pressure as the required value for the injection pressure. The maximum value of the injection pressure is determined from the change in the injection pressure over time. The molding judgment unit 58 compares the maximum value of the injection pressure, which is the required value, with the maximum injection pressure, which is the specification information for each injection molding machine 16.

[0080] The molding determination unit 58 determines that an injection molding machine 16 having a maximum injection pressure equal to or less than the required value is an unsuitable molding machine. For each injection molding machine 16 having a maximum injection pressure greater than the required value, the molding determination unit 58 compares the required values ​​obtained from the analytical molding results with the specification information for other items as well. The molding determination unit 58 determines that an injection molding machine 16 whose specification information satisfies the required values ​​for all items is a suitable molding machine.

[0081] The required values ​​for each item are determined as follows. The molding judgment unit 58 determines the maximum value of the injection rate as the required value for the injection rate. The maximum value of the injection rate is determined from the change in the injection rate over time in the analytical molding results. The molding judgment unit 58 also determines the maximum value of the injection volume as the required value for the injection volume. The maximum value of the injection volume is determined from the change in the injection volume over time in the analytical molding results. The molding judgment unit 58 also determines the maximum value of the mold clamping force as the required value for the mold clamping force. The maximum value of the mold clamping force is determined from the change in the mold clamping force over time in the analytical molding results. The molding judgment unit 58 also sets the required values ​​for the mold to the mold dimensions, which are the analytical molding results.

[0082] The required values ​​are not limited to those indicated by numerical values. For example, the required values ​​for the resin include the properties of the barrel and nozzle, such as corrosion resistance and abrasion resistance of the barrel and nozzle.

[0083] 11 is a map showing the barrel specifications (barrel performance, nozzle performance) required when molding using various types of resin. For example, when the resin used to mold the target molded product is a liquid crystal polymer, the molding determination unit 58 determines the barrel specifications to be "high corrosion resistance and high wear resistance." In other words, the required values ​​for the resin are "high corrosion resistance and high wear resistance."

[0084] The method for determining the required value for each item is not limited to the above. For example, the molding determination unit 58 may use the peak injection pressure, which is the result of analytical molding, as the required value for the injection pressure.

[0085] The molding determination unit 58 may also determine the maximum value of the injection rate as the required value for the injection rate. The maximum value of the injection rate is determined from the change over time in the injection speed, which is the analytical molding result, and the screw diameter of the model used in the analysis by the resin flow analysis device 14.

[0086] Furthermore, the molding determination unit 58 may use the required value for the injection volume as the volume of the molded product, which is the analytical molding result.

[0087] The molding determination unit 58 may also determine the maximum injection volume as the required value for the injection volume. The maximum injection volume is determined from the injection stroke, which is the analytical molding result, and the screw diameter of the model used in the analysis by the resin flow analysis device 14.

[0088] 12 is a flowchart showing the process of displaying information about a molding machine that is performed in the management device 12. The process of displaying information about a molding machine that is performed when, for example, an operator issues an instruction via the input unit 66 to execute the process of displaying information about a molding machine that is capable of molding.

[0089] In step S1, the specification information acquisition unit 54 acquires specification information from each injection molding machine 16. Then, the process proceeds to step S2.

[0090] In step S2, the mold information acquisition unit 52 acquires the analytical molding results from the resin flow analysis device 14. Then, the process proceeds to step S3.

[0091] In step S3, the molding determination unit 58 determines whether each injection molding machine 16 is capable of molding. Then, the process proceeds to step S4.

[0092] In step S4, the display control unit 60 displays the machine information of the moldable machine on the display unit 18. Thereafter, the moldable machine information display process ends.

[0093] [Effects] In the management device 12 of this embodiment, the molding determination unit 58 determines whether each injection molding machine 16 is a machine capable of molding, based on the analytical molding results generated by the resin flow analysis device 14 and the specification information of each injection molding machine 16. The display control unit 60 displays information indicating each machine capable of molding on the display unit 18. This allows the worker to understand the information indicating each machine capable of molding by looking at the display on the display unit 18.

[0094] In the management device 12 of this embodiment, the display control unit 60 causes the display unit 18 to display a graphic indicating the installation location of a moldable machine in a first mode, and causes the display unit 18 to display a graphic indicating the installation location of a non-moldable machine in a second mode different from the first mode. This allows the worker to easily understand the installation location of the moldable machine by looking at the display on the display unit 18.

[0095] In the management device 12 of this embodiment, the display control unit 60 displays machine information such as the model name of each moldable machine, the serial number of each moldable machine, the installation location of each moldable machine, the operating status of each moldable machine, the operating schedule of each moldable machine, and the type of resin being used by each moldable machine on the display unit 18. This allows the worker to easily understand the machine information of the moldable machine by looking at the display on the display unit 18.

[0096] In the injection molding system 10 of this embodiment, the molding information output unit 64 of the management device 12 outputs molding information to each of the capable molding machines selected by the capable molding machine selection unit 62. Each injection molding machine 16 acquires the molding information supplied from the management device 12 by the molding information acquisition unit 40. This allows the injection molding system 10 to automatically send molding information from the management device 12 to the capable injection molding machines 16.

[0097] Second Embodiment The management device 12 of the first embodiment sets required values ​​for each item based on the analytical molding results generated by the resin flow analysis device 14 for the mold of the target molded product. Alternatively, the management device 12 may set required values ​​for each item based on analytical molding conditions generated by the resin flow analysis device 14 for the mold of the target molded product. In this case, the mold information acquisition unit 52 acquires analytical molding conditions for the mold of the target molded product from the resin flow analysis device 14. The other configurations of the management device 12 are the same as those of the first embodiment.

[0098] The molding determination unit 58 determines the required value for each item from the analytical molding conditions. For example, the molding determination unit 58 sets the required value for the injection rate to the set injection rate, which is an analytical molding condition. The molding determination unit 58 also sets the required value for the resin to the set resin temperature, which is an analytical molding condition.

[0099] The required values ​​for each item may include a mixture of required values ​​determined from analytical molding results and required values ​​determined from analytical molding conditions.

[0100] The molding determination unit 58 determines whether the specification information of each injection molding machine 16 satisfies the required values ​​for each item of each injection molding machine 16. The molding determination unit 58 determines an injection molding machine 16 that satisfies the required values ​​for all items as a molding-compatible machine. On the other hand, the molding determination unit 58 determines an injection molding machine 16 that does not satisfy one or more of the required values ​​for each item as an unsuitable machine.

[0101] [Effects] In the management device 12 of this embodiment, the molding determination unit 58 determines whether each injection molding machine 16 is a machine capable of molding, based on the analytical molding conditions generated by the resin flow analysis device 14 and the specification information of each injection molding machine 16. The display control unit 60 displays information indicating each machine capable of molding on the display unit 18. This allows the worker to understand the information indicating each machine capable of molding by looking at the display on the display unit 18.

[0102] [Third embodiment] The management device 12 of the first embodiment sets the required values ​​for each item based on the analytical molding results generated by the resin flow analysis device 14 corresponding to the mold of the target molded product. In contrast to this, the management device 12 may set the required values ​​for each item based on the actual molding results generated by each injection molding machine 16 corresponding to the mold of the target molded product.

[0103] In this case, the mold information acquisition unit 52 acquires actual molding results corresponding to the molds of the target molded products from each injection molding machine 16. The other configurations of the management device 12 are the same as those in the first embodiment.

[0104] The molding judgment unit 58 determines the required value for each item from the actual molding results. For example, the molding judgment unit 58 determines the maximum value of injection pressure as the required value for injection pressure. The maximum value of injection pressure is determined from the change over time in injection pressure in the actual molding results. The molding judgment unit 58 also determines the maximum value of injection rate as the required value for injection rate. The maximum value of injection rate is determined from the change over time in injection speed in the actual molding results and the screw diameter of the injection molding machine 16. The molding judgment unit 58 also determines the maximum value of injection volume as the required value for injection volume. The maximum value of injection volume is determined from the injection stroke in the actual molding results and the screw diameter of the injection molding machine 16.

[0105] The required values ​​for each item may include a mixture of required values ​​obtained from analytical molding results, required values ​​obtained from analytical molding conditions, and required values ​​obtained from actual molding results.

[0106] The molding determination unit 58 determines whether the specification information of each injection molding machine 16 satisfies the required values ​​for each item of the injection molding machine 16. The molding determination unit 58 determines an injection molding machine 16 that satisfies the required values ​​for all items as a molding-compatible machine. On the other hand, the molding determination unit 58 determines an injection molding machine 16 that does not satisfy one or more of the required values ​​for each item as an unsuitable molding machine.

[0107] [Operation and Effect] In the management device 12 of this embodiment, the molding determination unit 58 determines whether each injection molding machine 16 is a machine capable of molding, based on the actual molding results generated by each injection molding machine 16 and the specification information of each injection molding machine 16. The display control unit 60 displays information indicating each machine capable of molding on the display unit 18. This allows the worker to understand the information indicating each machine capable of molding by looking at the display on the display unit 18.

[0108] [Fourth embodiment] The management device 12 of the first embodiment sets the required values ​​for each item based on the analytical molding results generated by the resin flow analysis device 14 in correspondence with the mold of the target molded product. The management device 12 may also set the required values ​​for each item based on the actual molding conditions generated by each injection molding machine 16 in correspondence with the mold of the target molded product.

[0109] In this case, the mold information acquisition unit 52 acquires actual molding conditions corresponding to the mold of the target molded product from each injection molding machine 16. The other configurations of the management device 12 are the same as those in the first embodiment.

[0110] The molding judgment unit 58 determines the required value for each item from the actual molding conditions. For example, the molding judgment unit 58 determines the maximum injection rate as the required value for the injection rate. The maximum injection rate is determined from the set injection speed, which is the actual molding condition, and the screw diameter of the injection molding machine 16. The molding judgment unit 58 also determines the maximum clamping force as the required value for the clamping force. The maximum clamping force is determined from the set clamping force, which is the actual molding condition. The molding judgment unit 58 also sets the required value for the resin to the set resin temperature, which is the actual molding condition.

[0111] In addition, the required values ​​for each item may be a mixture of required values ​​obtained from analytical molding results, required values ​​obtained from analytical molding conditions, required values ​​obtained from actual molding results, and required values ​​obtained from actual molding conditions.

[0112] The molding determination unit 58 determines whether the specification information of each injection molding machine 16 satisfies the required values ​​for each item of each injection molding machine 16. The molding determination unit 58 determines an injection molding machine 16 that satisfies the required values ​​for all items as a molding-compatible machine. On the other hand, the molding determination unit 58 determines an injection molding machine 16 that does not satisfy one or more of the required values ​​for each item as an unsuitable molding machine.

[0113] [Operation and Effect] In the management device 12 of this embodiment, the molding determination unit 58 determines whether each injection molding machine 16 is a machine capable of molding, based on the actual molding results generated by each injection molding machine 16 and the specification information of each injection molding machine 16. The display control unit 60 displays information indicating each machine capable of molding on the display unit 18. This allows the worker to understand the information indicating each machine capable of molding by looking at the display on the display unit 18.

[0114] Fifth Embodiment In the management device 12 of this embodiment, an operator can select items to be compared when determining whether a machine is capable of molding.

[0115] 13 is a block diagram showing the configuration of the injection molding system 10. The configurations of the resin flow analysis device 14 and the multiple injection molding machines 16 are the same as those in the first embodiment.

[0116] The calculation unit 48 of the management device 12 has a reception unit 88. The reception unit 88 is realized by the calculation unit 48 executing a program stored in the storage unit 50. The other configurations of the management device 12 are the same as those in the first embodiment.

[0117] The reception unit 88 receives the selection by the operator of the items used in determining which machines are capable of molding.

[0118] 14 is a diagram showing the screen of the display unit 18 on which the item selection input unit 89 is displayed. The item selection input unit 89 has check boxes 90 corresponding to the items. The worker can input a check mark into the check box 90 by operating the input unit 66. The item corresponding to the check box 90 into which a check mark has been input becomes the item selected by the worker.

[0119] The molding judgment unit 58 compares the analytical molding results generated by the resin flow analysis device 14 for the selected items with the specification information of each injection molding machine 16, and judges each injection molding machine 16 as to whether it is a molding-capable machine.

[0120] [Effects] In the management device 12 of this embodiment, the reception unit 88 receives selections by an operator for items used in determining whether a machine is capable of molding. The molding determination unit 58 compares the analytical molding results generated by the resin flow analysis device 14 with the specification information of each injection molding machine 16 for the selected items, and determines whether each injection molding machine 16 is capable of molding. This makes it possible to determine whether each injection molding machine 16 is capable of molding, based on the items selected by the operator.

[0121] 15 is a block diagram showing the configuration of an injection molding system 10. The configurations of a resin flow analysis device 14 and a plurality of injection molding machines 16 are the same as those in the first embodiment.

[0122] The calculation unit 48 of the management device 12 has a connected device information acquisition unit 92, a required device information acquisition unit 94, and a missing device determination unit 96. The connected device information acquisition unit 92, the required device information acquisition unit 94, and the missing device determination unit 96 are realized by the calculation unit 48 executing a program stored in the storage unit 50. The other configurations of the management device 12 are the same as those in the first embodiment.

[0123] The connected device information acquisition unit 92 acquires connected device information, which is information about peripheral devices connected to each injection molding machine 16. The connected device information is stored in the memory unit 34 of each injection molding machine 16. The peripheral devices include a resin dryer, a mold temperature regulator, etc.

[0124] The necessary equipment information acquisition unit 94 acquires necessary equipment information, which is information on peripheral equipment required when molding the target molded product. The necessary equipment information may be stored in the storage unit 22 of the resin flow analysis device 14. The necessary equipment information may also be stored in the storage unit 34 of each injection molding machine 16.

[0125] The insufficient equipment determining unit 96 compares the connected equipment information of each moldable machine with the necessary equipment information of the target molded product, and determines the peripheral equipment that will be insufficient for each moldable machine when molding the target molded product.

[0126] The display control unit 60 causes the display unit 18 to display information about peripheral devices that are lacking in each molding machine.
