One problem with forming resin products by blow molding is that defects such as uneven thickness of the resin can occur (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-95159 [Patent Document 2] Japanese Patent Publication No. 2022-180542 Summary of the Invention [Problem to be solved by the invention]

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.

[0005] An object of the present invention is to provide a method for appropriately presenting the types and amounts of adjustment of parameters to be adjusted among parameters related to molding processing of resin molding. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention employs the following configuration.

In particular, since the condition of each part of the molded product is measured and the parameters to be adjusted and the amounts of adjustment are determined for each part, appropriate adjustments can be made according to the condition of each part.

[0015] The control unit may also determine the type of defect in each part based on the difference between the measurement result and a reference value, and set the parameter associated with the type of defect as the parameter to be adjusted, thereby enabling appropriate and efficient setting of the parameter to be adjusted.

[0016] The control unit may also use the trained model to determine the types of parameters to be adjusted and the amounts of adjustment of the parameters based on the measurement results. This allows the adjustment targets to be set appropriately and efficiently.

DETAILED DESCRIPTION OF THE INVENTION

[0022] 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.

[0023] §1 Application Examples The present invention can be applied to the adjustment of parameters related to molding of each part in a molding machine that molds resin products by blow molding. Figure 1 shows an example 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 areas of a resin bottle, "uneven thickness," "whitening," and "misalignment" in the bottom area, parameters are adjusted to control molding in response to the defect state.

[0024] "Meat accumulation" is a condition where excess resin accumulates in areas such as the base of the neck, while "uneven thickness" is a condition where the resin is formed thicker than normal. In particular, a molding defect where uneven thickness occurs around the neck or shoulder area, forming a ring shape, is sometimes called a "ring." Uneven thickness and "whitening" are conditions where 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.

[0025] The present invention proposes the type and amount of adjustment of parameters to be adjusted among molding-related parameters 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, the pressure during blowing, etc. The type and amount of adjustment of parameters to be adjusted are proposed for each location of the molded product.

[0026] §2 Configuration example (1. Hardware Configuration) FIG. 2 is a diagram illustrating an example of a hardware configuration of a 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 nonvolatile 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.

[0027] (2. Functional Configuration) FIG. 3 is a diagram showing the configuration of a system including a parameter adjustment support device 1. In FIG. 3, a molding machine 50 is a molding machine that molds a resin product by blow molding, and an inspection device 200 is a device that measures the state of each portion of a molded product molded by the molding machine 50. The parameter adjustment support device 1 is a device that proposes the type of parameters to be adjusted in the molding of each portion and the amount of adjustment of the parameters based on measurement results of the molded product obtained by the inspection device 200. A measurement result acquisition unit 101 and a parameter presentation unit 102 represent functional modules of a program executed by a processor 11 of the parameter adjustment support device 1. The measurement result acquisition unit 101 has a function of acquiring measurement results regarding the state of each portion of a molded product measured by the inspection device 200. Furthermore, the parameter presentation unit 102 has a function of presenting, for each portion of the molded product, the type of parameters to be adjusted and the amount of adjustment of the parameters, among parameters related to the molding process of the molded product, based on the measurement results acquired from the inspection device 200. 3, the molding machine 50, the inspection device 200, and the parameter adjustment support device 1 are configured as independent devices, but they may be configured as one device that includes the functions of the three devices. Also, the molding machine 50 and the parameter adjustment support device 1 may be configured as one device, or the inspection device 200 and the parameter adjustment support device 1 may be configured as one device.

[0028] §3 Example of operation Next, the operation of the parameter adjustment support device 1 according to this embodiment will be described with reference to the flowchart in Fig. 4. The parameter adjustment support device 1 calculates adjustment amounts of parameters when molding a resin product by blow molding, and presents the amounts to the user.

[0029] 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. An example of the excitation light L1 is ultraviolet light in a specific wavelength range. 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.

[0030] As shown in FIG. 5, the inspection device 200 includes a camera (image acquisition unit) 203 that acquires an image based on fluorescence generated by irradiating the molded article 201 with ultraviolet light. The inspection device 200 also includes a control unit 204 that measures the state of each part of the molded article 201 based on the acquired image. Specifically, the presence or absence of defects in each part 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 part measured by the control unit 204. Note that the measurement results are not limited to the state of each part measured based on an image captured by irradiating the molded article 201 with ultraviolet light. For example, the measurement results may also include measurements of the dimensions and thickness of each part of the molded article 201.

[0031] Next, the parameter presenting unit 102 determines, based on the acquired measurement results, for each part of the molded product, the type of parameters to be proposed for adjustment from among the parameters related to the molding process of the molded product, and the amount of adjustment of the proposed parameters (step S102).

[0032] 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 magnitude (P1P, etc.) during molding.

[0033] 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 forming the "shoulder" in accordance with each defect state.

[0034] 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 the 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 body 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.

[0035] Furthermore, the parameter presenting unit 102 determines the amount of adjustment of the parameter to be proposed as an adjustment target. The amount of adjustment 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 amount of adjustment may be set in five stages, such as "+Adjustment Required" when the parameter needs to be increased due to a significant defect (such as increasing the set temperature), "+Caution Required" when there is a slight defect and the parameter needs to be increased slightly, "Normal" when no defect is observed, "-Caution Required" when there is a slight defect and the parameter needs to be decreased slightly, and "-Adjustment Required" when there is a significant defect and the parameter needs to be decreased.

[0036] The parameter presenting unit 102 can perform the above-mentioned five-level classification using, for example, a decision tree with each evaluation value as an input, but other classification algorithms may also be used.

[0037] Furthermore, the parameter presenting unit 102 may use a trained model to determine the type of parameter to be proposed as an adjustment target and the adjustment amount of the parameter 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 a combination of the parameters to be adjusted and the adjustment amount for each body part as training data. The adjustment amount of the parameter may be set using the above-mentioned stage evaluation.

[0038] The types of parameters proposed as adjustment targets and the adjustment amounts of the parameters determined by the parameter presenting unit 102 are output, for example, to the monitor of the parameter adjustment support device 1. 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 adjustment contents shows the blow molding parameter adjustment procedure (STEP 1 "Neck and Shoulder Adjustment" → STEP 2 "Bottom Adjustment" → STEP 3 "Overall Balance Adjustment"). Selecting each step displays the parameters to be adjusted for the region where the parameter adjustment is performed in the selected step and the adjustment range. For example, in the example of FIG. 7, selecting STEP 1 "Neck and Shoulder Adjustment" clearly displays the parameters (H1 to H3) to be adjusted in molding the neck and shoulder region and their respective adjustment ranges.

[0039] 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.

[0040] An operator or the like may change the parameter settings for the molding process in the molding machine 50 based on the type of parameter to be adjusted and the amount of parameter adjustment presented by the parameter presenting unit 102. The parameter adjustment is set to be reflected in the molding process of the target region. For example, parameter adjustment for the neck and shoulder regions is set to be reflected in the molding of the neck and shoulder regions. Note that the parameter adjustments presented by the parameter presenting unit 102 may be automatically reflected in the molding machine 50. Specifically, the functions of the molding machine 50 and the parameter adjustment support device 1 may be implemented in a single device, so that the presented parameter adjustment values are automatically reflected. Furthermore, a user may be allowed to change the parameter adjustment values presented by the parameter presenting unit 102, and a learning model may be reconfigured based on the user's changes to the parameter adjustment values, and the trained model that presents the parameter adjustment values may be updated to the reconfigured learning model. The user's changes may be fine adjustments made multiple times. A history of such user changes to the parameter adjustment values may be recorded, and the trained model may perform machine learning again using this change history. In this way, by using machine learning to learn how a user adjusts parameters, a tool can be obtained that can make decisions comparable to those of an experienced worker, etc., and more appropriate parameter adjustment values can be presented. In this way, once the tool's accuracy becomes sufficiently high through machine learning, the parameter adjustment values may be automatically reflected in the molding machine 50.

[0041] Furthermore, 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 function of the parameter presenting unit 102.

[0042] As described above, according to this embodiment, one or more measurement results regarding the condition of each portion of a resin molded product are acquired, 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. This allows the types and adjustment amounts of parameters proposed for adjustment among the parameters related to the resin molding process to be presented separately for each portion, allowing workers and others to confirm the presented parameter adjustment contents for each portion. Furthermore, it is also possible to make adjustments so that the overall balance of the molded product is achieved.

[0043] 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.
