Description

[Technical Field]

[0001] The present invention relates to an identification management system and an identification management method. [Background technology]

[0002] In recent years, due to environmental and resource issues, manufacturers of products are being asked to work on recycling resources such as plastics. These plastics have good processability and can be given functionality through compounding, so they are used in a wide variety of products. When recycling plastics, the processing method is selected based on the recycling method, taking into account the type and composition of the resin, the product's intended use, and historical information such as past usage.

[0003] For example, Patent Document 1 describes a plastic identification device that irradiates crushed mixed plastics being transported by a transport means with laser light, detects reflected or scattered light from the crushed mixed plastics with a detection element, and identifies the type of plastic and its additives based on the detection results.The device is configured to drip liquid onto the surface of the crushed mixed plastics, and this solves the problem that when strong laser light is irradiated onto black plastic containing carbon filler, the plastic melts due to heat generated by absorption by the carbon filler, making it impossible to measure the Raman scattering spectrum.

[0004] In addition, information on the plastic materials used in products is written directly on the product (ISO), on labels affixed directly to the product, and on product packaging and accompanying documents, making it possible for the information to be referenced. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-122969 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned prior art can improve the accuracy of identifying crushed plastics, but it is not possible to ascertain the usage history.

[0007] Furthermore, with plastic products, it is difficult to determine the type and composition of the resin from its appearance or to obtain information on its usage management history. The information provided by ISO and JIS is limited to the type of resin and the main additives, and affixing labels to small products can affect the design and pose a risk of information loss if the label peels off, making it difficult to determine the type and composition of the resin or obtain information on its usage management history.

[0008] Product packaging and accompanying documents can be lost or change hands during the period from product use to disassembly and disposal, making it difficult to confirm correspondence. Furthermore, because the quality of collected products depends on their usage history, it is desirable to manage them individually (by ID), but conventional label and code markings pose a risk of tampering. Furthermore, labels require measures to prevent and separate them from becoming mixed in as foreign matter when recycled.

[0009] The object of the present invention has been made in view of the above-mentioned problems, and is to provide an identification management system and an identification management method for individually managing the life cycle of a molded product from its design to manufacture, use, and disposal. [Means for solving the problem]

[0010] In order to solve the above problem, the identification management system of the present invention that manages the traceability of molded bodies comprises a molded body information acquisition unit that acquires image information of the molded body, an identification information conversion unit that converts a random pattern in a specified area of ​​the image information into identification information, and an information control unit that performs processing to store manufacturing information or life cycle information of the molded body for each of the identification information in a molded body management database. [Effects of the Invention]

[0011] According to the present invention, it is possible to individually and seamlessly collect and manage management information throughout the life cycle not only for a product but also for each molded body that constitutes the product. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the embodiments of the present invention are not limited to the embodiments described below, and various modifications are possible within the scope of the technical concept. Note that corresponding parts in each drawing used to describe each embodiment described below will be designated by the same reference numerals, and duplicated explanations will be omitted.

[0014] First, an outline of a method for identifying molded bodies made of thermoplastic resin or the like in the identification management system of the embodiment will be described.

[0015] Thermoplastic resins are suitable as the base material of the molded body to be identified from the viewpoint of moldability and material recycling, and examples include polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene copolymer synthetic resin (ABS), polyvinyl alcohol (PVA), polyvinyl chloride (PVC), polycarbonate (PC), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polyether ether ketone (PEEK), ethylene vinyl acetate copolymer (EVA), polylactic acid (PLA), polybutene (PC), and polypropylene (PP). They are made of thermoplastic resins such as polyethylene succinate (PBS), polybutylene adipate terephthalate resin (PBAT), thermoplastic starch, polyhydroxybutyrate (PHB), 3-hydroxybutyrate-co-3-hydroxyhexanoate polymer (PHBP), polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene (ETFE), perfluoroalkoxyalkane (PFA), ethyl trifluoroacetate (EFA), polychlorotrifluoroethylene (PCTFE), and ethylene-chlorotrifluoroethylene copolymer (ECTFE).

[0016] The additives are preferably compatible with the molding and processing process of the base material after mixing and are retained in the base material. For the thermoplastic resins mentioned above, the additives are selected from mica, talc, carbon, nitrides, metals (aluminum, gold, silver, etc.), metal oxides (zinc oxide, titanium oxide, iron oxide, silicates, etc.), metal hydroxides (aluminum hydroxide, magnesium hydroxide, etc.), clay minerals, glass particles, urethane resins, organic pigments (azo compounds, phthalocyanine compounds), glass fiber, carbon fiber, hemp fiber, wheat straw, rice straw, and other plant fibers, as well as wood flour, bamboo flour, coffee bean grounds, and tea leaves.

[0017] When using metals, metal oxides, and metal nitrides as a resin base material, magnesium and aluminum are preferred because they are less susceptible to oxidation reactions due to the catalytic action of metal ions (the Redox reaction). When using particles of zinc, silver, calcium, titanium, nickel, vanadium, iron, copper, manganese, or oxides and nitrides containing these, it is preferable to coat the particle surface with silicate or other materials to prevent the generated radicals from acting on the resin, or to add stabilizers such as radical chain initiation inhibitors, radical scavengers, and peroxide separators to the base material. When the molded product is used in an environment exposed to ultraviolet light, such as outdoors, the use of particles of zinc oxide or titanium oxide whose surface is coated with silicate, which absorbs ultraviolet light, can suppress deterioration of the base resin.

[0018] The base material of the molded body is not limited to thermoplastic resin, but may be metal, ceramic, or glass.

[0019] In this embodiment, a case will be described in which the base material of the molded body is PP, and mica, talc, carbon, or hemp fiber is used as the additive.

[0020] The molded body to be identified in this embodiment is molded by injecting a thermoplastic resin matrix mixed with additives. The flow of the matrix during injection changes the distribution of the additives, resulting in the appearance of a random pattern with low reproducibility due to the additives in the structure and interfaces. This random pattern differs for each injection-molded molded body and also differs depending on the location on the molded body.

[0021] The identification management system of this embodiment uses this pattern as identification information for each molded body, thereby improving the traceability of the molded body.

[0022] Figure 1 shows an example of a molded product to be identified. The molded product has a random pattern (random dot pattern) on its surface that is difficult to reproduce due to additives. The surface of the molded product also displays a recycling identification mark that is engraved into the mold and appears during injection molding. In addition to the recycling identification mark, the material of the plastic part, the recycling mark, or markings to facilitate manual disassembly and sorting of plastic and other parts may also be used.

[0023] The identification management system of the embodiment captures an image of the surface of a molded product and digitizes the image information to create identification information. Since the random dot pattern on the surface of a molded product is different for each individual molded product, the identification information obtained from image information of a specified area on the surface of the molded product is different for each individual molded product. The identification management system of the embodiment individually manages the life cycle of each molded product, from manufacture, use, to disposal, based on this identification information.

[0024] The identification management system of the embodiment converts image information of a molded body into identification information by digitizing it in a two-dimensional coordinate system.

[0025] In detail, the identification management system of the embodiment uses a method of arranging information of each coordinate of the image information according to a specified rule by binarizing it based on a threshold (for example, 0 and 1), by grayscale signal intensity (for example, 256 gradations), or by color information (for example, color coding to RGB), a method of digitizing the signal intensity distribution (for example, a ratio of 0 and 1 by binarization), a method of acquiring it as a spatial frequency, a method of acquiring it as a parcel ... vinegar The image data is converted into identification information by machine learning, according to a conversion algorithm created separately using tent homology. In this embodiment, the image data of the molded body is binarized, described in a matrix, and then converted into identification information by an identification information conversion means, such as a method of arranging the binarized image data according to a rule.

[0026] In addition, the identification management system of the embodiment may convert the number of singular points of a random pattern in a specified area of ​​the imaging information, the arrangement of the pattern, the area ratio of the pattern, the contrast of a specified area of ​​the imaging information, or the chromaticity of a specified area into identification information.

[0027] Next, the area of ​​the image information (image area) for acquiring the identification information of the molded body will be described. The imaging area is the outer periphery of the molded body or a part of the molded body, and may be any shape such as a rectangular area or a circular area.

[0028] When a portion of a molded body is used as the imaging area, the imaging area may be an area of ​​a predetermined size that is centered around a mark such as a recycling identification mark, as shown in Figure 1, or an area of ​​a predetermined size that is a predetermined distance away from the position of a mark such as a recycling identification mark. When a part of the molded body is used as the imaging region, a unique position and region size of the random pattern appearing in at least one part of the molded body are selected.

[0029] Other examples of the molded body will be described with reference to FIGS. 2A, 2B, 2C, and 2D.

[0030] FIG. 2A is a diagram showing an example of a molded product with a matte texture. FIG. 2B is a diagram showing an example of a molded product with a stone pattern. FIG. 2C is a diagram showing an example of a marble-patterned molded product. FIG. 2D is a diagram showing an example of a molded product on which a streaky fractal pattern containing hemp fibers is formed. FIG. 2E is a diagram showing an example of a molded product with a noise pattern. FIG. 2F is a diagram showing an example of a particle-patterned molded body made by mixing flake-shaped luster materials, mica, and aluminum.

[0031] The identification management system of the embodiment will be specifically described below. FIG. 3 is a diagram illustrating a configuration of an identification management system according to an embodiment.

[0032] The identification management system of the embodiment is composed of an identification management device 6 consisting of a molded body information acquisition unit 1 that acquires imaging information of the molded body, an identification information conversion unit 2 that converts the imaging information acquired by the molded body information acquisition unit 1 into identification information, an input unit 4 that inputs manufacturing information of the molded body and traceability information of the molded body, a display unit 5 that displays the converted identification information and traceability information of the molded body corresponding to the identification information, and an information control unit 8 that manages the manufacturing information of the molded body and the traceability information of the molded body based on the identification information, and a molded body management database 3 (hereinafter also referred to as molded body management DB3) that is connected to the identification management device 6 via a network 7 and stores traceability information of the molded body based on the identification information converted by the identification information conversion unit 2.

[0033] In detail, the molded body information acquisition unit 1 uses visible light and infrared light that do not affect the strength of the molded body. Line Random patterns and marks of the microstructure and interface of the molded body are obtained by non-destructive measurement using electromagnetic waves or ultrasonic waves.

[0034] The molded body information acquisition unit 1 is composed of a semiconductor sensor such as a CMOS image sensor or a CCD image sensor, or a light receiving device such as a high frequency electron multiplier, and a laser scanning means such as a galvanometer mirror. The molded body information acquisition unit 1 may also be equipped with an electromagnetic wave irradiation device for irradiating the molded body with electromagnetic waves.

[0035] The identification management device 6 in the identification management system of this embodiment is used by sellers, users, collectors, and final disposers of molded bodies to be identified or products containing molded bodies. In this case, the molded body information acquisition unit 1 of the identification management device 6 can be a separate device, such as a handheld terminal or smartphone with an optical camera, as shown in Figure 4. This allows reading operations to be performed anywhere.

[0036] The identification management device 6 in the identification management system of the embodiment is used by manufacturers of molded bodies to be identified or products made of molded bodies, manufacturers of recycled products of molded bodies, sorting processors, and recycling processors. In this case, the molded body information acquisition unit 1 of the identification management device 6 is preferably a fixed camera, as shown in Figure 5, which illuminates the molded body with an illumination light source to acquire image information of the molded body.

[0037] Returning to FIG. 3, the identification information conversion unit 2 of the identification management device 6 digitizes the image information of the random pattern of the molded body acquired by the molded body information acquisition unit 1 and converts it into identification information.

[0038] FIG. 6 is a flow diagram of the conversion process of the identification information by the molded body information acquisition unit 1 and the identification information conversion unit 2. FIG. 6 is a flow diagram in the case where an area at a predetermined distance from the position of a mark such as the recycling identification mark described in FIG. 1 is used as the imaging area.

[0039] In step S61, the molded body information acquisition unit 1 captures an image of the molded body and obtains a captured image of the surface of the molded body.

[0040] In step S62, the molded body information acquisition unit 1 determines whether or not a mark such as a recycling identification mark is included in the captured image acquired in step S61, and if it is included (Yes in S62), the process proceeds to step S63. If it is not included (No in S62), the process returns to step S61 and acquires a captured image of the molded body again.

[0041] In step S63, the molded body information acquisition unit 1 cuts out, as image information, information on an area of ​​a predetermined size at a position a predetermined distance away from the position of the mark in the captured image.

[0042] In step S64, the identification information conversion unit 2 binarizes the imaging information extracted in step S63, describes it in a matrix, arranges it in accordance with a rule, encodes it, and converts it into identification information.

[0043] In step S65, the identification information conversion unit 2 determines whether the imaging information was successfully converted into identification information in step S64, and if the conversion was successful (Yes in S65), the process ends. If the conversion was not successful (No in S65), the process returns to step S61 and the identification information conversion process is repeated.

[0044] In step S65, if the identification information conversion unit 2 has not been able to perform the conversion normally, it may display a warning to prompt the user to re-photograph the molded product or change the imaging conditions.

[0045] 3, the molded body management DB 3 that stores traceability information of molded bodies will be described. The molded body management DB 3 makes it possible to manage information related to the life cycle of a molded body. The information control unit 8 accesses the molded body management DB 3 based on the identification information of the molded body converted by the identification information conversion unit 2. The information control unit 8 performs processing such as storing manufacturing information and life cycle information of the molded body in the molded body management DB for each piece of identification information.

[0046] The molded body management DB3 is a memory unit that stores a database consisting of molded body manufacturing information 31, molded body sales information 32, usage information 33, collection information 34, sorting processing information 35, recycling processing information 36, and final disposal information 27 for each molded body identification information.

[0047] In the molded body management DB3, records are generated based on identification information obtained by photographing the molded body when the molded body is manufactured, and a field for molded body manufacturing information 31 is stored. In addition, a field for sales information 32 is stored when the molded body or a product containing the molded body is sold.

[0048] Similarly, a field for usage information 33 is stored when the molded body or a product containing the molded body is used, a field for collection information 34 is stored when the molded body or a product containing the molded body is collected, a field for sorting information 35 is stored when the molded body or a product containing the molded body is sorted, a field for recycling information 36 is stored when the molded body is recycled, and a field for final disposal information 37 is stored when the molded body is finally disposed of.

[0049] FIG. 7 is a diagram showing details of the field configuration of the manufacturing information 31 in the compact management DB 3. As shown in FIG.

[0050] The manufacturing information 31 is composed of, for each molded body identification information (ID), the molded body name, molding and manufacturing method, manufacturer, manufacturing date, names and ratios of resin blends, names and ratios of additives, and the name of the product to which the molded body is applied. If the molded body is composed of multiple resin blends and additives, the names and ratios of each resin blend and the names and ratios of the additives are stored. Note that the constituent materials of the molded body and the energy consumption and carbon dioxide emissions related to molding and manufacturing may also be stored.

[0051] In addition, the manufacturing information 31 may also store the origin of the material of the molded body, such as recycled materials or biomass, certification information such as UL certification, biomass-related certification, or RoHS (Restriction of the Use of Certain Hazardous Substances), the reading position of the imaging information that is converted into identification information for the molded body, energy consumption related to manufacturing and life cycle, and carbon dioxide emissions related to manufacturing and life cycle.

[0052] FIG. 8 is a diagram showing the detailed configuration of sales information 32, use information 33, recovery information 34, sorting information 35, recycling information 36, and final disposal information 37 (hereinafter collectively referred to as life cycle information) in the compact management DB 3.

[0053] The life cycle information indicates traceability information, and for each molded product's identification information (ID), it consists of the reader of the molded product, the reading location, the product status, recycling, disposal / recycling (incineration or landfill), and the disposal / recycling processor. The reader, reading location, and product status acquire the molded product's identification information and store the molded product's status throughout its life cycle from manufacture to use to disposal. The energy consumption and carbon dioxide emissions during the molded product's life cycle from manufacture to use to disposal may also be stored. Furthermore, if the molded product moves from one location to another during its life cycle, the means of transportation, such as transporting the molded product, and the associated energy consumption and carbon dioxide emissions may also be stored.

[0054] For example, sales information 32, use information 33, recovery information 34, sorting information 35, recycling information 36, and final disposal information 37 are stored, each including reader, reading location, and manufacturing information.

[0055] Figure 3 illustrates an example in which the identification management device 6 and molded body management DB3 of the embodiment of the identification management system are connected to the network 7 in a 1:1 relationship, but the configuration may also be such that multiple identification management devices 6 and molded body management DB3s are connected to the network 7.

[0056] In addition, Figure 3 shows an example in which the identification information conversion unit 2 that converts the identification information of the molded body from the image information is provided in the identification management device 6, but it is also possible to provide a conversion server that performs identification information conversion on the network, send the image information to the conversion server, have the conversion server convert it into identification information, and notify the identification management device 6. At this time, the image information or the identification information may be compressed or encrypted.

[0057] In the encryption, the image area of ​​the molded body, the identification information conversion means, and the identification information (ID) converted from the image information by the identification information conversion means such as a conversion algorithm may be used as the encryption key. Finger The image area of ​​the molded body, the conversion algorithm and the identification information are transmitted to the designated reader and administrator. Conversion section The identification management device 6 in which the conversion algorithm is implemented is pipe Reason of relationship To By disclosing and providing the information as an authorized encryption key, it is possible to prevent reading or access to information by anyone other than those involved in lifecycle management.

[0058] Next, a method for managing molded bodies using the identification management system of the embodiment will be described in detail with reference to FIG.

[0059] Figure 9 shows the flow of each process of manufacturing, selling, using, collecting, separating, recycling, or final disposal of products containing molded bodies. In Figure 9, the process from manufacturing to recycling or final disposal is considered to be one cycle, and if the molded bodies are recycled after cycle c=1, cycle c=2 is performed.

[0060] The subscripts of each process indicate this cycle. The use process is divided into different use processes using subscripts from -1 to -j according to changes in the product user and the place of use.

[0061] In the method for managing molded bodies using the identification management system of the embodiment, in each process of product manufacturing, sales, use, collection, sorting, recycling, or final disposal, identification information of the molded body is acquired by the molded body information acquisition unit 1 and the identification information conversion unit 2 of the identification management device 6 as described in FIG. 6 , The information control unit 8 of the identification management device 6 records the manufacturing information or life cycle information in the molded body management DB 3. Note that in the sales process, there are cases where the manufacturing information or life cycle information is not recorded.

[0062] The following sections will explain in detail each process of product manufacturing, sales, use, collection, sorting, recycling or final disposal.

[0063] First, the manufacturing process of the product will be described. The molding machine for molded bodies consists of a mixer for mixing the PP base material of the molded body with additives, and an injection molding machine that heats and melts the mixture and injects it into a mold. If the injection molding machine is a rotating shaft extrusion type with a mixing function, the molding machine for molded bodies may consist of only the injection molding machine.

[0064] If the base material is a thermoplastic resin other than PP, equipment such as extrusion molding, press molding, die coating, flow molding, printing, spray coating, 3D printing, and cutting can be applied depending on the base material.

[0065] The injection molded parts are assembled and inspected to become a finished product. At this time, the manufacturer acquires the identification information of the molded body from the image information of a predetermined area of ​​the molded body using the identification management device 6, and stores the manufacturing information described in Figure 7 in the molded body management DB 3 in correspondence with the identification information.

[0066] In the product sales process, when the product arrives, is stored, or is shipped, the seller uses the identification management device 6 to obtain identification information for the molded body from image information of a specified area of ​​the molded body, and records the life cycle information of the reader, reading location, and product status described in Figure 8 in the molded body management DB3 corresponding to the identification information.

[0067] During the product usage process, when the user purchases, owns, transfers, or disposes of the product, the user uses the identification management device 6 to obtain identification information for the molded body from image information of a specified area of ​​the molded body, and records the life cycle information of the reader, reading location, and product status described in Figure 8 in the molded body management DB3 corresponding to the identification information. If there are multiple users, the life cycle information is recorded for each user.

[0068] In the product collection process, the collector collects products discarded by users, acquires the identification information of the molded product from image information of a predetermined area of ​​the molded product using the identification management device 6, and records the life cycle information of the reader, reading location, and product state explained in Fig. 8 in the molded product management DB 3 in correspondence with the identification information. Then, the collector transfers the product to the sorting process.

[0069] In the product collection process, the collector may refer to the manufacturing information in the molded body management DB3 based on the acquired identification information, obtain information on the product's recycling market, processing costs, laws and regulations, etc., determine whether the product is eligible for disposal, and if so, transfer the product to the final disposal process. Also, the collector may refer to the life cycle information in the molded body management DB3 and transfer the product to the final disposal process depending on the product condition.

[0070] In the product sorting process, the sorter sorts products transferred from the product collection process at the time of receipt, storage, or removal, and obtains identification information for the separated molded bodies from image information of a specified area of ​​the separated molded bodies using the identification management device 6. Corresponding to the identification information, the sorter records the life cycle information of the reader, reading location, and product state explained in Fig. 7 in the molded body management DB 3. The sorter then transfers the separated molded bodies to a recycling process or a final disposal process.

[0071] In detail, in the sorting process, the sorter obtains information from outside about the product condition, the product recycling market, processing costs, laws and regulations, etc., and determines whether the molded body can be recycled based on the life cycle information corresponding to the identification information of the sorted molded body. If the molded body can be recycled, Growth The molded body is transferred to the recycling process, and if it is not recyclable, it is transferred to the final disposal process. The result of this judgment on whether it can be recycled or not is recorded in the life cycle information corresponding to the identification information.

[0072] In the product recycling process, the recycling processor obtains identification information for molded bodies transferred from the sorting process from image information of a specified area of ​​the molded body using the identification management device 6, and then refers to the molded body management DB3 to obtain life cycle information corresponding to the identification information.

[0073] The recycler then determines whether to reuse the compact or to crush it and recycle it as a base material based on the life cycle information of the compact. The result of the reuse or recycling decision is recorded in the life cycle information corresponding to the identification information, and the compact to be reused and the crushed compact are transferred to the manufacturing process for recycled products.

[0074] In more detail, when recycling molded bodies, recyclers crush molded bodies that have the same names and ratios of resin blends and additives as the manufacturing information corresponding to the identification information, and use this as the base material for the molded body of the recycled product.

[0075] In the final disposal process of the product, the final disposer acquires the identification information of the molded body from the image information of a predetermined area of ​​the molded body using the identification management device 6, and records the life cycle information of the reader, reading location, and product state explained in Fig. 7 in the molded body management DB 3 in correspondence with the identification information, as well as the disposal / recycling process and the disposal / recycling processor of the life cycle information.The final disposer then disposes of the product.

[0076] In the manufacturing process for recycled products, which is a cycle of c=2, when a molded body is reused, the manufacturing information and life cycle information in the molded body management DB3 corresponding to the identification information of the molded body are reused, and the settings for the product name in the manufacturing information, the disposal / recycling process in the life cycle information, and the disposal / recycling processor in the life cycle information are cleared.

[0077] In the manufacturing process for recycled products, when a molded body is recycled, identification information for the manufactured molded body is obtained from image information of a specified area of ​​the molded body, and the manufacturing information described in Figure 7 is stored in the molded body management DB3 corresponding to the identification information.

[0078] The subsequent processes of sale, use, collection, sorting, recycling or final disposal of recycled products in the c=2 cycle are carried out in the same way as in the c=1 cycle.

[0079] As described above, in each process of product manufacturing, sales, use, collection, sorting, recycling or final disposal, manufacturing information and life cycle information are set in the molded body management DB3 based on the identification information of the molded body converted from image information of a specified area of ​​the molded body by the identification management device 6, and the identification management system of the embodiment manages the life cycle of the molded body from manufacturing, use to disposal.

[0080] In addition, real-time manufacturing information and lifecycle information can be shared with stakeholders in each process of the lifecycle via Network 7, and seamless information can be created and provided to lifecycle management supervisors and supervisory agencies.

[0081] Furthermore, the present invention is not limited to the above-described embodiments, and includes various modifications. The above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
