Embodiments of the present disclosure will be described below with reference to the drawings. However, the embodiments described below are merely examples, and are not intended to exclude various modifications and application of techniques not explicitly described below. The present disclosure can be implemented in various modifications (for example, by combining each embodiment) without departing from the gist of the disclosure.

1. First Embodiment Hereinafter, a sorting system according to a first embodiment and an apparatus for sorting and collecting packaging materials realized by using the sorting system will be described. First, with reference to FIGS. 1 and 2, the basic configuration and the function of each part of the sorting system 1 and the sorting and collecting apparatus 10 according to the first embodiment will be described. FIG. 1 is a block diagram showing one configuration example of functions and operations of the sorting system 1. As shown in FIG. FIG. 2 is a schematic diagram showing an example of the external appearance of the separate collection device 10. As shown in FIG.

(1.1) Basic Configuration of Sorting System The sorting system 1 according to the present embodiment is part of a recycling system that recycles packaging materials. The packaging materials sorted by material, for example, by the sorting system 1 are collected at a recycler's centralized base, separated, pulverized, washed, and recycled by material. More specifically, when each separated material is a resin material, each material is processed into resin flakes, resin pellets, or the like. Resin flakes and resin pellets are recycled (horizontal recycling) into the same product as before recycling (for example, from a resin bottle to a resin bottle), or recycled into a different product (from a resin bottle to a pouch) (cascade recycling).

The sorting system 1 is, for example, a system for operating the sorting and collecting apparatus 10 shown in FIG. Each function of the sorting system 1 is constructed by cooperating.
First, the packaging material 30 sorted by the sorting system 1 and the individual identification information 31 given to the packaging material 30 will be described.

<Packaging material>
The packaging material 30 is a container that accommodates contents having various shapes such as liquids, powders, and solids, and is formed of, for example, a resin bottle, a resin package, a pouch, a laminate, or the like. Pouches and laminates are formed, for example, by covering a base material printed with a product name, etc., with a resin, and are formed into a bag shape by a single layer of one material or a laminated film of a plurality of materials. . Resin bottles and resin packages are made of one or more kinds of resin materials and are formed in a desired packaging material shape, and a resin film (shrink film) or the like printed with a product name or the like is wrapped around the outer surface. , or the resin film is removed. The packaging material 30 may be made of any material and may have any shape as long as the contents can be accommodated inside. Other shapes and materials may be used.

<Individual identification information>
The individual identification information 31 is, for example, given to the packaging material 30 and is associated with information indicating the materials forming the packaging material 30 . The individual identification information 31 is, for example, a one-dimensional code such as a JAN code printed on the packaging material 30, a two-dimensional code such as a QR code (registered trademark), a pattern other than these codes, and a special code. may Further, the individual identification information 31 may be, for example, a three-dimensional pattern such as an uneven pattern on the surface of the packaging material 30 or a random pattern. That is, the individual identification information 31 may be any information as long as the feature point information unique to the packaging material 30 can be identified from the image. When the individual identification information 31 is a one-dimensional code or a two-dimensional code, etc., the individual identification information 31 is printed (an example of addition) on the packaging material 30, and when the individual identification information 31 is a three-dimensional pattern, etc., the individual identification information 31 is provided as an uneven shape on the surface of the packaging material 30 .

The individual identification information 31 has different unique features, and is formed so that each packaging material 30 has different feature point information. Therefore, by analyzing the individual identification information 31 attached to the packaging material 30 of the product, each manufactured product is distinguished and the material of the packaging material 30 to which the individual identification information 31 is attached is specified. can do.

As a result, the sorting system 1 stores the feature point information extracted from the read individual identification information 31, the stored feature point information, and at least the material of the packaging material 30 in association with each other, and stores the packaging material information storage unit (details will be described later). ), at least the material of the packaging material 30 is discriminated. In this case, since the feature point information and various information about the packaging material 30 can be stored in association with each other, necessary information can be extracted from the related information that is greater than or equal to the amount of information of the two-dimensional code and sorted. It is also possible to acquire information about the packaging material 30 after sorting and collecting and to analyze the collected information.

Further, the individual identification information 31 may be a two-dimensional code or the like including information indicating the material of the packaging material 30 and other information. That is, the sorting system 1 may directly read the information indicating the material of the packaging material 30 from the individual identification information 31 to determine the material of the packaging material 30 .

The sorting system 1 for sorting the packaging materials 30 to which such individual identification information 31 is attached will be described in detail below.
As shown in FIG. 1, the sorting system 1 includes an individual identification information acquisition unit 11 that acquires an image (individual identification information image) of the individual identification information 31 attached to the packaging material 30, and a material that constitutes each packaging material. It is provided with a packaging material information storage unit 12 for storing information, a material determination unit 13 for determining materials constituting the packaging material 30, and a sorting control unit 14 for sorting and controlling the packaging material 30 for each material. The individual identification information acquisition section 11 is connected to the imaging section 20, for example.

The use of such individual identification information 31 is preferable in that it is inexpensive, easy, and does not require a carrier such as a chip for individual identification.
For example, as a method for individual identification of packaging materials, individual serial numbers such as ID-NEX (registered trademark) are issued, and the corresponding two-dimensional code, etc. is printed on the package, or printed on a seal and attached to the package. Pasting, or pasting an IC chip from which an individual serial number or the like can be read out to a package has been performed.
However, it is not preferable to affix a seal or the like to the packaging material to be recycled, and there is a risk that the consumer may remove the seal or the like before collection. In addition, it is not realistic from the viewpoint of cost to attach an expensive individual identification chip or the like to the packaging material to be discarded.

Therefore, by using the individual identification information 31 printed on the packaging material 30 or the individual identification information 31 using the uneven pattern on the surface of the packaging material 30, the individual identification information 31 is added to the packaging material 30 without cost. It is preferable because it can In addition, it is possible to prevent the individual identification information 31 from being removed before the packaging material 30 is collected, thereby preventing the identification of the material.
Furthermore, as the individual identification information 31, codes such as JAN code, DataMatrix code, and QR code (registered trademark) printed on the packaging material 30 can be used. It is preferable because it is possible to operate the separation system 1 without giving it to.

<Imaging unit>
The imaging unit 20 is, for example, a camera, and images the individual identification information 31 attached to the packaging material 30 to generate an individual identification information image 21 of the individual identification information 31 . The individual identification information 31 attached to the packaging material 30 is imaged by the imaging unit 20 when the packaging material 30 is collected, so that the material of the collected packaging material 30 can be discriminated and collected separately. Become.

The imaging wavelength range of the imaging unit 20 may be selected according to the imaging environment. The imaging wavelength band of the imaging unit 20 may be the wavelength band of visible light or the wavelength band of invisible light such as infrared rays and ultraviolet rays. Further, the resolution of the individual identification information image 21 acquired by the imaging unit 20 may be set to a high level that allows the individual identification information 31 to be accurately recognized, and is set to 300 dpi or higher, for example.
The imaging unit 20 generates an individual identification information image of the individual identification information 31 and inputs it to the individual identification information acquisition unit 11 .

<Individual identification information acquisition unit>
As shown in FIG. 1 , the individual identification information acquisition section 11 has an image acquisition section 111 and an image analysis section 112 .

(Image acquisition unit)
The image acquisition section 111 of the individual identification information acquisition section 11 acquires the individual identification information image 21 of the individual identification information 31 attached to the packaging material 30 . The image acquisition unit 111 acquires the individual identification information image 21 transmitted from the imaging unit 20, for example. The individual identification information image 21 is associated with information indicating the material that constitutes the packaging material 30 .

The individual identification information image 21 acquired by the image acquisition unit 111 may be subjected to size change (enlargement, etc.), noise removal, binarization, etc. as preprocessing for image analysis. The image acquisition unit 111 outputs the acquired individual identification information image 21 to the image analysis unit 112 .
Note that the image acquisition unit 111 may acquire the individual identification information image 21 obtained by imaging the individual identification information 31 . For this reason, the image acquisition unit 111 obtains not only the individual identification information image 21 captured by the image capturing unit 20, but also the individual identification information image 21 captured by the image capturing unit of a mobile terminal such as a smart phone, and a USB memory or the like. The individual identification information image 21 stored in a storage medium, the individual identification information image 21 once stored on a server, or the like may be acquired.
The image acquisition unit 111 outputs the individual identification information image 21 preprocessed as necessary to the image analysis unit 112 .

(Image analysis part)
The image analysis unit 112 of the individual identification information acquisition unit 11 extracts feature point information from the individual identification information image 21 generated by imaging the individual identification information 31 attached to the packaging material 30 . Extraction of feature point information analyzes the individual identification information image 21 and extracts feature point information of the individual identification information 31 displayed in the individual identification information image 21 using an image recognition technique. The image analysis unit 112 performs preprocessing such as, for example, processing to match the vertical and horizontal directions of the code to a predetermined direction by rotating the image, noise removal, correction of image distortion, and adjustment of saturation and brightness. After that, feature point information is extracted. As a result, it is possible to specify the packaging material 30 used for the product by specifying the product from the feature point information. materials and lamination structure of each layer) can be discriminated.

In this embodiment, the "feature point" refers to a feature unique to each image that cannot be distinguished by the human eye or a code reading unit such as a scanner. It means a characteristic pattern shape or the like for each information 31 . Specifically, the feature points are the edge linearity at the end of the individual identification information 31, the contrast between the bright color area and the dark color area, the pattern difference (extra dark color area), the partial blurring of the print, and the outline aspect. Information such as ratio, arrangement position and pattern size.

The image analysis unit 112 focuses on the feature points as described above, and converts each feature into numerical feature point information. In forming the individual identification information 31, various environments such as vibration of the forming apparatus that naturally occurs during formation, formation speed, coating speed, materials such as ink, formation tolerance, room temperature, humidity, and vibration of the packaging material 30 during formation. Factors cause subtle differences. Although such differences are difficult for the human eye to visually recognize, they can be recognized by analyzing feature points using image recognition technology. The feature point data is information specific to an individual and is information that uniquely identifies the individual.

<Packaging material information storage unit>
The packaging material information storage unit 12 stores feature point information extracted from the individual identification information image 21 generated by imaging the individual identification information 31 assigned to the packaging material 30 in advance (for example, before shipment from the factory), A material constituting the packaging material 30 to which the individual identification information 31 is attached is stored in association with the material.
New information is added to the feature point information and the material constituting the packaging material 30 stored in the packaging material information storage unit 12 each time the product is shipped. For this reason, the sorting system 1 periodically acquires the feature point information of the individual identification information 31 and the materials constituting the packaging material 30 via, for example, the Internet, etc., and stores them in the packaging material information storage unit 12. Update existing information by adding new information.

When the packaging material 30 is a laminate, the packaging material information storage unit 12 stores the material of each layer constituting the packaging material 30 and the laminated structure of each layer as the material of the packaging material 30 . For example, when the packaging material 30 has a layer structure (PE/PET/ONY) in which polyethylene (PE), polyethylene terephthalate (PET) and oriented nylon (ONY) are laminated in this order, the packaging material information storage unit 12 stores this It stores the layer structure and the material of each layer. As a result, when recycling the packaging material 30 having a laminated structure, it is possible to separate the packaging materials 30 having the same layer structure. In addition, since the layer structure of the collected packaging material 30 has already been determined when the packaging material 30 is collected, it is possible to easily determine the method of separating each layer of the packaging material 30 having a laminated structure.

The packaging material information storage unit 12 may store feature point information, materials constituting the packaging material, and product identification information for identifying the product of the packaging material in association with each other. Here, the "product identification information" includes, for example, information that can identify the product name and manufacturer name of the product. As for the "product name", different product names are assigned to products having the same contents (for example, detergent) but different capacities. Specifically, when the individual identification information 31 is a JAN code, the product identification information is a GS1 business code that identifies the manufacturer name and a product item code that identifies the product name included in the JAN code. In addition, the "product identification information" may further include other information, such as the manufacturing history of the product using the packaging material 30, the name of the manufacturing factory that generated the contents of the packaging material 30, and information on the manufacturing equipment. and the date and time of manufacture of the content, etc. may be included.

<Material discrimination part>
Based on the individual identification information image 21 acquired by the individual identification information acquisition unit 11, the material discrimination unit 13 discriminates the material constituting the packaging material 30 to which the individual identification information 31 is assigned. More specifically, the material determination unit 13 compares the feature point information extracted from the individual identification information image 21 acquired by the individual identification information acquisition unit 11 and the feature point information stored in the packaging material information storage unit 12, A material associated with the individual identification information 31 having matching feature point information is determined as a material forming the packaging material 30 .
The material determination unit 13 compares the feature point information extracted by the individual identification information acquisition unit 11 and the feature point information stored in the packaging material information storage unit 12, and determines the material associated with the matching feature point information. It is discriminated as a material constituting the packaging material 30 .

<Segregation control section>
The sorting control section 14 controls the sorting of the packaging materials 30 based on the materials of the packaging materials 30 determined by the material determination section 13 . For example, when the sorting control unit 14 determines the material based on the individual identification information 31 read by the imaging unit 20 when the packaging material 30 is collected, the sorting control unit 14 stores the packaging material 30 in different storage units for each material. A sorting section (details of which will be described later) is controlled so as to be accommodated.

(1.2) Sorting and Collecting Apparatus Subsequently, the sorting and collecting apparatus 10, one configuration example of which is shown in FIG. 2, will be described with reference to FIGS. 1 and 2. FIG. The sorting and collecting device 10 is controlled by the sorting system 1 and automatically performs sorting/collecting operations.
As shown in FIG. 2, the sorting and collecting apparatus 10 includes an imaging unit 20, a sorting unit 25 that temporarily stores and sorts the packaging materials 30, and sorts the packaging materials 30 sorted by the sorting unit 25 by material. A plurality of housing portions 26 (three housing portions 26A, 26B, and 26C in FIG. 2) are provided. The sorting and collecting apparatus 10 also includes an individual identification information acquisition unit 11, a packaging material information storage unit 12, a material discrimination unit 13, and a sorting control unit 14 (see FIG. 1) inside the device.
The sorting and collecting apparatus 10 will be described below. Note that the imaging unit 20, the individual identification information acquisition unit 11, the packaging material information storage unit 12, the material determination unit 13, and the separation control unit 14 of the sorting and collecting apparatus 10 have the same configurations as those of each unit of the sorting system 1. omitted.

<Sorting section>
The sorting unit 25 sorts the packaging material 30 based on the materials determined by the material determining unit 13 . For example, the sorting section 25 can temporarily store the packaging material 30, and sort the packaging material 30 into an appropriate storage section 26 (for example, one of the storage sections 26A, 26B, and 26C) according to the control of the sorting control section 14. distribute. The sorting unit 25 may have any configuration as long as the packaging material 30 can be sorted. A configuration (not shown) for distributing to either is used.

<Accommodation part>
The storage unit 26 stores packaging materials 30 that are made of the same material. FIG. 2 shows an example of storage sections 26A, 26B, and 26C that separately store two types of materials. The accommodating part 26 (26A, 26B, 26C) may have any form as long as it can accommodate a plurality of packaging materials 30, and may be, for example, a box, a basket, a bag, or the like.
The storage units 26 (26A, 26B, 26C) store the packaging materials 30 sorted by the sorting unit 25 based on the individual identification information 31 given to the packaging materials 30, respectively.

The sorting and collecting apparatus 10 is placed, for example, in a shop front of a store such as a supermarket, or in a facility of a municipality. In this case, the user causes the sorting and collecting device 10 to read the individual identification information 31 attached to the packaging material 30, so that the packaging material 30 is sorted by material and collected.
Note that the collected packaging materials 30 are periodically collected by, for example, a recycling company or the like, and collected at an intensive base. The sorting and collecting apparatus 10 installed at a storefront or the like needs to have a relatively small outer shape due to the problem of installation space. For this reason, the types of materials for the packaging material 30 that can be sorted may be relatively small.
Further, the sorting and collecting device 10 may be arranged at a collection point such as a recycling company. Such a sorting and collecting device 10 may be a device that is sufficiently larger than a device that is placed at the storefront of a store such as a supermarket.

(1.3) Modification As described above, the sorting system 1 according to the present embodiment uses information acquired via the Internet or the like to store the Although the stored information is updated and the materials are discriminated in the sorting and collecting apparatus 10, the configuration is not limited to this.
For example, as shown in FIG. 3A, the packaging material information storage unit 12 and the material discrimination unit 13 may be connected to the separate collection device 10 via the Internet or the like. In this case, the sorting system 1 transmits the acquired characteristic point information to the material discriminating unit 13 outside the sorting and collecting apparatus 10 via the Internet or the like, and the material discriminating unit 13 transmits the material discrimination result via the Internet. Output to the separation control unit 14 .
Alternatively, as shown in FIG. 3B, one of the packaging material information storage unit 12 and the material identification unit 13 may be connected to the separate collection device 10 via the Internet or the like.

(1.4) Effect of this embodiment The sorting system and the sorting and collecting apparatus according to this embodiment have the following effects.
(1) The sorting system discriminates the material constituting the packaging material from the individual identification information given to the packaging material, and sorts the packaging material based on the discriminated material.
Therefore, it is possible to collect packaging materials having various materials and layer configurations without mixing them, and it is possible to efficiently recycle packaging materials that have not been recycled conventionally. In addition, the quality of the recycled packaging material is improved, and the usage of the recycled material can be expanded. Furthermore, the material of the packaging material is clear at the time of collection, which facilitates the collection of specific materials and improves the recycling rate.

(2) The sorting system includes a packaging material information storage unit that stores in advance the feature point information extracted from the individual identification information and the materials that make up the packaging material in association with each other.
As a result, it is possible to appropriately determine the material of the packaging material based on the individual identification information given to the packaging material.
(3) When the packaging material is collected, the sorting system extracts feature point information from the individual identification information image, compares the feature point information with the feature point information stored in the packaging material information storage unit, It is distinguished from the material that constitutes the packaging material.
As a result, it is possible to easily sort the packaging materials by material when collecting them.
(4) The sorting system stores the material of each layer constituting the packaging material, which is a laminate, and the laminated structure of each layer as the material of the packaging material.
As a result, it is possible to efficiently separate packaging materials having a laminated structure.

2. 2nd embodiment Hereinafter, the classification system 2 which concerns on 2nd embodiment is demonstrated with reference to FIG. FIG. 4 is a block diagram showing one configuration example of the sorting system 2 according to the second embodiment.

(2.1) Basic Configuration of Sorting System As shown in FIG. 4, the sorting system 2 includes an individual identification information acquisition unit 11, a packaging material information storage unit 12, a material discrimination unit 13, a sorting control unit 14, and a copy determination unit 27 . In other words, the sorting system 2 is different from the sorting system 1 in that it includes a duplicate determination unit 27 and determines whether the individual identification information image 21 acquired by the image acquisition unit 111 is a duplicate.
The duplication determination unit 27 will be described in detail below. Also, the image acquisition unit 111 and the packaging material information storage unit 12 are the same as those of the sorting system 1, so description thereof will be omitted.

(Duplicate determination unit)
The duplication determination unit 27 determines whether or not the individual identification information 31 is duplicated individual identification information. Specifically, the duplication determination unit 27 determines a method of attaching the individual identification information 31 to the packaging material 30 ( For example, it has a forming method determination unit 271 that determines a printing method).

For example, FIGS. 5A to 5C show enlarged portions of individual identification information printed by different printing methods. 5(A) and 5(B) show part of the individual identification information printed by offset printing, and FIG. 5(C) shows the individual identification information of FIG. 5(A) copied by a laser copier. Part of the individual identification information is shown. The individual identification information printed by offset printing in FIGS. 5(A) and 5(B) has high edge linearity at the end of the individual identification information, although there is a faint print with a different shape in the dark area. It's becoming FIGS. 5A and 5B are both examples of individual identification information printed by offset printing, and each individual identification information has minute individual differences. This is because even if the same printing method is used, the individual identification information may not be printed exactly the same due to differences in printing environments and conditions. can be determined.
On the other hand, the individual identification information shown in FIG. 5(C), which is obtained by copying the individual identification information shown in FIG. It can be determined that the printing method itself is different because the faintness is different from that of the original.

The forming method determination unit 271 determines the printing method based on the feature point information of the individual identification information 31 extracted from the individual identification information image 21, for example. The formation method determination unit 271 stores information on the printing method of the predetermined individual identification information 31 . Formation method determination unit 271 determines in advance the formation method of individual identification information 31 shown in individual identification information image 21 by comparing the feature point information of individual identification information 31 with a pre-stored correct printing method. It is possible to determine whether or not the formation method is the same. For example, the formation method determination unit 271 distinguishes between the genuine individual identification information 31 printed using a plate and the duplicated individual identification information 31 printed by reading the shape of the genuine individual identification information 31 and printing it with a copier or the like. It is possible to distinguish As a result, when the formation method determination unit 271 determines that the formation method of the individual identification information 31 shown in the individual identification information image 21 is not a predetermined formation method, the copy determination unit 27 performs the above-described individual identification method. The information 31 is determined to be duplicated individual identification information.
The duplicate discriminating section 27 outputs authenticity information indicating whether or not the individual identification information 31 is duplicated individual identification information to the material discriminating section 13 and the separation control section 14 .

It should be noted that a method other than the printing method determination may be used as the method of determining duplication of the individual identification information 31 . For example, when the uneven pattern on the surface of the packaging material 30 is used as the individual identification information 31, the duplicate determination unit 27 extracts the individual identification information image 21 from the image analysis unit 112. Based on the feature point information of the individual identification information 31, A pattern discriminating section 272 may be provided for discriminating whether the uneven pattern on the surface of the packaging material 30, which is the individual identification information 31, is a regular pattern.
Although FIG. 5 shows the forming method determination unit 271 and the pattern determination unit 272, only one of them may be provided depending on the packaging material 30 to be collected.

(Material discrimination section)
The material discriminating unit 13 acquires authenticity information, which is a determination result as to whether or not the individual identification information 31 is a copy, from the duplication discriminating unit 27 . When the material discrimination unit 13 acquires the authenticity information indicating that the individual identification information 31 is not the duplicated individual identification information, the material identification unit 13 packages the material corresponding to the same feature point information as the feature point information of the individual identification information 31. The material information storage unit 12 is searched and determined. On the other hand, when the material discriminating unit 13 acquires authenticity information indicating that the individual identification information 31 is duplicated individual identification information from the duplication discriminating unit 27, the feature point information and the packaging material information of the individual identification information 31 are obtained. The comparison with the feature point information stored in the storage unit 12 is stopped.

(Separation control unit)
The classification control unit 14 acquires authenticity information, which is the determination result of whether or not the individual identification information 31 is a duplicate, from the duplication determination unit 27 . When the sorting control unit 14 acquires authenticity information indicating that the individual identification information 31 is duplicated individual identification information, the sorting control unit 14 can sort the packaging materials 30 into, for example, the storage unit 26 that stores the packaging materials 30 whose materials are unknown. can.
