[0005] To improve molding defects, it is necessary to adjust the temperature control parameters, pressure control parameters, etc. during molding. However, there are many types of parameters to adjust, and the parameters to be adjusted and the amount of adjustment vary depending on the location and type of molding defect. Adjusting these parameters appropriately required the knowledge of experienced workers.

[0006] An object of the present invention is to provide a method for appropriately adjusting the types and amounts of parameters to be adjusted among parameters related to a molding process for resin molding.

[0020] An embodiment according to one aspect of the present invention (hereinafter also referred to as "the present embodiment") will be described below with reference to the drawings. However, the embodiment described below is merely an example of the present invention in all respects. Needless to say, various improvements and modifications can be made without departing from the scope of the present invention. In other words, when implementing the present invention, specific configurations according to the embodiment may be appropriately adopted. Note that, although data appearing in this embodiment is described in natural language, more specifically, it may be specified in any of computer-recognizable pseudo-language, commands, parameters, or machine language, but is not limited to these.

[0021] §1 Application Example The present invention can be applied to the adjustment of parameters related to the molding of each part in a molding machine that molds resin products by blow molding. Figure 1 shows examples of parameters that can be adjusted by the present invention. As shown in Figure 1, in order to improve defects that occur during molding, such as "uneven thickness" or "meat accumulation" in the neck and shoulder parts of a resin bottle, "uneven thickness," "whitening," and "misalignment" in the bottom part, parameters for molding control are adjusted to correspond to the defective state.

[0022] "Meat accumulation" is a condition in which excess resin accumulates in areas such as the base of the neck, and "uneven thickness" is a condition in which the resin is formed thicker than normal. In particular, a molding defect in which uneven thickness occurs around the neck or shoulders, creating a ring shape, is sometimes called a "ring." Furthermore, "whitening" is a condition in which the resin is formed thinner than normal, appearing whitish. The presence or absence of these defects can be determined by analyzing fluorescent images obtained by irradiating it with ultraviolet light or by measuring the thickness using laser irradiation.

[0023] The present invention proposes the type and amount of adjustment of molding-related parameters to be adjusted based on the location where the defect occurs and the type of defect obtained as described above. Parameters to be adjusted include, for example, the heating temperature of the preform by the heater and the pressure during blowing. The type and amount of adjustment of the parameters to be adjusted are proposed for each location of the molded product. The present invention also provides a user interface that allows the user to change the amount of adjustment of the proposed parameters.

[0024] §2 Configuration Example (1. Hardware Configuration) FIG. 2 is a diagram showing an example of the hardware configuration of the parameter adjustment support device 1 according to this embodiment. The parameter adjustment support device 1 is a computer including a processor 11, a main memory 12, an input / output interface 13, a communication interface 14, and a storage device 15. The storage device 15 is a computer-readable recording medium such as a semiconductor memory (which may be, but is not limited to, a volatile memory or a non-volatile memory) or a disk medium (which may be, but is not limited to, a magnetic recording medium or a magneto-optical recording medium). The storage device 15 stores a program to be executed by the processor 11. The program is read from the storage device 15 into the main memory 12 and interpreted and executed by the processor 11, thereby performing various functions.

[0025] (2. Functional Configuration) FIG. 3 is a diagram showing the configuration of a system including the parameter adjustment device 1. In FIG. 3, the molding machine 50 is a molding machine that molds a resin product by blow molding, and the inspection device 200 is a device that measures the state of each portion of the molded product molded by the molding machine 50. The parameter adjustment device 1 is a device that proposes the type of parameters to be adjusted in molding of each portion and the amount of adjustment of the parameters based on the measurement results of the molded product obtained by the inspection result 200. The measurement result acquisition unit 101, the parameter presentation unit 102, the parameter display unit 103, and the parameter change acceptance unit 104 represent functional modules of a program executed by the processor 11 of the parameter adjustment device 1. In addition, a change history recording unit 111 is implemented in the storage device 15. The measurement result acquisition unit 101 has a function of acquiring measurement results related to the state of each portion of the molded product measured by the inspection device 200. Furthermore, the parameter presenting unit 102 has a function of presenting, for each part of the molded product, the type of parameters to be adjusted and the adjustment amount of the parameters among the parameters related to the molding process of the molded product, based on the measurement results obtained from the inspection device 200. The parameter display unit 103 has a function of displaying the values ​​of each presented parameter. The parameter change receiving unit 104 has a function of receiving an operation to change the value of each displayed parameter. In the example shown in FIG. 3, the molding machine 50, the inspection device 200, and the parameter adjusting device 1 are each configured as independent devices, but they may also be configured as a single device that includes the functions of the three devices. Furthermore, the molding machine 50 and the parameter adjusting device 1 may be configured as a single device, or the inspection device 200 and the parameter adjusting device 1 may be configured as a single device.

[0026] §3 Operation Example Next, the operation of the parameter adjustment support device 1 according to this embodiment will be described using the flowchart in Fig. 4. The parameter adjustment support device 1 calculates the amount of parameter adjustment when molding a resin product by blow molding and presents it to the user.

[0027] First, the measurement result acquisition unit 101 acquires one or more measurement results regarding the condition of each portion of a resin molded product (step S101). A method for acquiring measurement results for a molded product will be described with reference to FIG. 5 . FIG. 5 illustrates an example of a molded product inspection device 200. As shown in FIG. 5 , the inspection device 200 is equipped with a light source 202 capable of irradiating a molded product 201 (e.g., a resin bottle) with light in a specific wavelength range. The inspection device 200 utilizes the property that, when excitation light L1 in a specific wavelength range is irradiated onto the molded product 201, detection target light L2 in a specific wavelength range different from the wavelength range of the excitation light L1 is emitted from the molded product 201, and the intensity of the detection target light L2 increases as the thickness and density of the molded product 201 increase. Ultraviolet light in a specific wavelength range can be used as an example of the excitation light L1. The presence or absence of defects in each portion of the molded product 201 is measured using fluorescence generated in response to irradiation with ultraviolet light as detection target light L2.

[0028] As shown in FIG. 5 , the inspection device 200 includes a camera (image acquisition unit) 203 that acquires images based on fluorescence generated by irradiating the molded product 201 with ultraviolet light. The inspection device 200 also includes a control unit 204 that measures the state of each portion of the molded product 201 based on the acquired images. Specifically, the presence or absence of defects in each portion is determined based on the intensity of the detected fluorescence (detection target light L2 in a specific wavelength range). The measurement result acquisition unit 101 of the parameter adjustment support device 1 acquires measurement results related to the state of each portion measured by the control unit 204. Note that the measurement results are not limited to the state of each portion measured based on images captured by irradiating the molded product 201 with ultraviolet light. For example, the measurement results may also include measurements of the dimensions and thickness of each portion of the molded product 201.

[0029] Next, in the parameter presentation unit 102, based on the acquired measurement results, the type of parameters to be proposed for adjustment and the amount of adjustment of the proposed parameters are determined for each part of the molded product from among the parameters related to the molding process of the molded product (step S102).

[0030] FIG. 6 is a diagram illustrating a method for selecting parameters to be adjusted. As shown in FIG. 6, evaluation values ​​relating to one or more conditions are shown as measurement results for eight regions (neck, shoulder, upper torso, middle torso, lower torso, bottom rise, installation portion, and bottom). For example, for the region "neck," multiple evaluation values ​​relating to the presence or absence of "meat pockets" are shown as defective conditions. Based on the multiple evaluation values, the parameter presenting unit 102 determines the types of parameters to be proposed as adjustment targets when molding the "neck." Parameters to be adjusted include the heater temperature (H1, etc.) and pressure (P1P, etc.) during molding.

[0031] Similarly, for the "shoulder" portion, evaluation values ​​regarding the presence or absence of "whitening" and "uneven thickness" are displayed as defect states. The parameter presenting unit 102 determines the type of parameters to be proposed as adjustment targets when molding the "shoulder" in accordance with each defect state.

[0032] The evaluation value indicates the difference from the reference value, and if it deviates significantly from the reference value, it is indicated by "+". If the value is close to the reference value, it is indicated by "±d". The evaluation value is the maximum brightness value, average brightness, etc. obtained from images of each part of the molded product. Note that these evaluation values ​​are determined based on the intensity of fluorescence emitted by irradiating the molded product with ultraviolet light, but the evaluation value is not limited to these. For example, the evaluation value may be the deviation from the reference value of measured values ​​such as height and barrel diameter obtained by irradiating the molded product with visible light and taking an image, or the deviation from the reference value of measured values ​​such as buckling strength and full pour capacity.

[0033] Furthermore, the parameter presenting unit 102 determines the adjustment amount of the parameter to be adjusted. The adjustment amount may be indicated by a specific numerical value or an adjustment range (such as the percentage of adjustment), or may be set using a plurality of stage evaluations. Specifically, the adjustment amount may be set in five stages, such as "+Adjustment Required" when the defective state is significant and the parameter needs to be increased (such as by increasing the set temperature), "+Caution Required" when there is a slight defect and the parameter needs to be slightly increased, "Normal" when no defect is observed, "-Caution Required" when there is a slight defect and the parameter needs to be slightly decreased, and "-Adjustment Required" when there is a significant defect and the parameter needs to be decreased.

[0034] The parameter presenting unit 102 can perform the above-described five-level classification using, for example, a decision tree with each evaluation value as input, but other classification algorithms may also be used.

[0035] Furthermore, the parameter presenting unit 102 may use a trained model to determine the types of parameters to be proposed as adjustment targets and the adjustment amounts of the parameters based on the measurement results. The trained model is a model that has been trained using the measurement results acquired by the measurement result acquiring unit 101 and combinations of the parameters to be adjusted and the adjustment amounts for each body part as training data. The adjustment amounts of the parameters may be set using the above-described stage evaluation.

[0036] Next, the parameter display unit 103 displays the types of parameters proposed as adjustment targets determined by the parameter presentation unit 102 and the adjustment amounts of the parameters on a monitor or the like of the parameter adjustment support device 1 (step S103). FIG. 7 is a diagram illustrating an example of a screen presenting proposed adjustment target parameters and adjustment amounts for each region. As shown in FIG. 7 , a column (S1) displaying measurement results for the target molded product and a column (S2) displaying parameter adjustment contents proposed based on the measurement results may be displayed. The column S1 displaying the measurement results displays measured values ​​of items indicating defects for each region. The column S2 displaying the adjustment contents shows the adjustment procedure for blow molding parameters (STEP 1 "neck and shoulder adjustment" → STEP 2 "bottom adjustment" → STEP 3 "overall balance adjustment"). When each STEP is selected, the adjustment target parameters and adjustment ranges for the region for which the parameters are to be adjusted in the selected STEP are displayed. For example, in the example of FIG. 7, when STEP 1 "neck and shoulder adjustment" is selected, the parameters (H1 to H3) to be adjusted in shaping the neck and shoulders and the adjustment range for each are displayed.

[0037] A user, such as an experienced worker, checks the displayed parameter types and their respective adjustment ranges and changes the adjustment ranges as necessary. Specifically, the user can increase the adjustment range to a desired value (by operating the up arrow button B1) or decrease it to a desired range (by operating the down arrow button B2) by operating the change buttons B1 and B2 displayed on the screen. The adjustment range may be changed by specifying a stepwise value (e.g., ±3%, ±5%, ±10%). Furthermore, when the user presses the adjustment completion button B3, the changes are confirmed, and the parameter change accepting unit 104 accepts the changes (step S104). The history of the accepted changes is recorded in the change history recording unit 111.

[0038] (Parameter Setting Based on Change History) The parameter presenting unit 102 may determine the parameters to be adjusted and the adjustment amounts based on the change history recorded in the change history recording unit 111. FIG. 8 is a diagram illustrating an example of a history of parameter changes made by a user. The screen illustrated in FIG. 8 may be displayed on a monitor or the like of the parameter adjustment support device 1. As shown in FIG. 8 , for example, in the neck and shoulder adjustment step, the heater temperature parameter H1 is changed from the initial output of 65% to 70% (+5% adjustment) in the first adjustment. Furthermore, the second adjustment changes the output from 70% to 75% (+5% adjustment), the third adjustment changes the output from 75% to 80% (+5% adjustment), the fourth adjustment leaves no change, and the fifth adjustment changes the output from 80% to 75% (-5% adjustment). Therefore, since the final value is changed from the initial 65% to 75%, a +10% adjustment of the parameter value is performed.

[0039] The parameter presenting unit 102 may perform machine learning of the learning model using the change history by the user as described above. That is, even if learning is performed using only the parameter value finally determined to be appropriate after several fine adjustments (in the example of H1 in FIG. 8 above, the adjustment range of +10%, which is the value after the fifth adjustment), the number of learning data is small and an appropriate adjustment range cannot be presented. On the other hand, by having the learning model learn the method of multiple fine adjustments by a veteran worker as shown in FIG. 8, it is possible to present a more appropriate adjustment range.

[0040] Furthermore, parameter settings in the shaping process may be changed based on the type of parameter to be adjusted and the amount of parameter adjustment determined by the parameter presenting unit 102. The parameter settings may be reflected in the shaping process of the target region according to the shaping process procedure. For example, parameter adjustments for the neck and shoulders are reflected in the shaping of the neck and shoulders.

[0041] Note that even for the same molded product, if there is a change in the shape or weight of the mold or preform used in blow molding, or the material used to manufacture the preform, the process of proposing the parameters to be adjusted and the adjustment amounts may be performed again, and the proposed content may be changed. Note that the proposal of the parameters to be adjusted and the adjustment amounts may be performed again not only when the conditions exemplified above are changed, but also when, for example, the environmental temperature or the weight of the preform changes.

[0042] The parameter adjustment support device 1 and the inspection device 200 may be implemented by a single device. Specifically, the control unit 204 of the inspection device 200 may implement the functions of the parameter presenting unit 102, the parameter display unit 103, and the parameter change accepting unit 104.

[0043] As described above, according to this embodiment, one or more measurement results regarding the condition of each portion of a resin molded product are obtained, and based on the measurement results, the types of parameters to be adjusted and the adjustment amounts of those parameters are presented for each portion of the molded product. The determined values ​​of each parameter are displayed on a monitor or the like, and the user can change the value of each parameter. This makes it possible to present to the user appropriate adjustment values ​​corresponding to the condition of each portion of the molded product, and to reflect the user's judgment of appropriateness based on their experience and changes to the adjustment values.

[0044] Although the embodiments of the present invention have been described in detail above, the above description is merely an example of the present invention in every respect, and it goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.
