[Modes for carrying out the invention]

[0008] The embodiments for carrying out the present invention will be described in detail below with reference to the drawings. However, the configurations, numerical values, processing flow, functional elements, etc., described in the following embodiments are merely examples, and they can be freely modified or changed, and the technical scope of the present invention is not intended to be limited to the following description.

[0009] A mounting frame for a hyperspectral camera according to a preferred embodiment of the present invention will be described with reference to Figures 1 to 7. The mounting frame 1 for the hyperspectral camera 11 is located outdoors. The mounting frame 1 is used to install the hyperspectral camera 11 in a predetermined position for estimating the type and quantity of waste 13 transported by a belt conveyor 14. Here, the waste 13 is a mixture of disaster waste (paper, wood, plastic, etc.) or industrial waste generated in large quantities outdoors.

[0010] In recent years, due to climate change and the increasing frequency and severity of natural disasters, a large amount of disaster waste has been generated every year. Since the quality (type) and quantity of disaster waste vary depending on the type of disaster and the location where it occurs, it has been necessary to quickly grasp the type and amount of waste generated and to optimize the processing methods according to the characteristics of each type of disaster.

[0011] In the prior art of this embodiment, as a method for easily identifying the type and amount of waste, there is a method using a hyperspectral camera. However, there was no device for using a hyperspectral camera, which is easily affected by ambient light, at an outdoor waste disposal site exposed to sunlight.

[0012] Referring to FIGS. 1 and 2, the configuration of the installation stand 1 will be described. The installation stand 1 is installed at an outdoor waste disposal site or the like. The installation stand 1 is arranged such that the frame portion 10 is installed so as to straddle the belt conveyor 14, and the hyperspectral camera 11 to be installed is positioned vertically above the flat belt of the belt conveyor 14. The installation stand 1 is installed at an arbitrary position on the belt conveyor 14, but is installed on the downstream side of the sieve 17 for sorting the waste 13 to be conveyed by the belt conveyor 14. The sieve 17 is a device for removing fine waste 13 from the waste 13 and sorting the waste 13 of a certain size.

[0013] For sieving, for example, a vibrating sieve or a rotary sieve can be used. As machines for performing such sieving, there are a vibrating sieve machine and a rotary sieve machine. A vibrating sieve machine (vibrating screen) for performing a vibrating sieve is a machine for sieving the input by vibrating the sieve net up and down. A rotary sieve machine (rotary sorter ( trommel sorter)) for performing a rotary sieve is a machine for sieving by rotating a cylindrical sieve surface.

[0014] The waste 13 sorted by the sieve 17 is conveyed by the belt conveyor 14. Then, the leveling jig 16 levels the height of the mass of the conveyed waste 13 to a constant height. The leveling jig 16 is provided at a predetermined height and horizontally with respect to the flat belt at a position immediately before the waste 13 placed on the flat belt passes under the frame portion 10 in the conveyance direction of the flat belt. Further, the leveling jig 16 is a rod-shaped (square bar) or plate-shaped jig for leveling the surface of the waste 13.

[0015] The leveling jig 16 is equal to, or approximately equal to, the width of the belt conveyor 14. The leveling jig 16 is positioned at a height of approximately 122 mm from the flat belt surface of the belt conveyor 14. Therefore, the height (thickness) of the waste 13 after leveling by the leveling jig 16 will be a maximum of 122 mm, although there will be some unevenness. The leveling jig 16 may be attached to the belt conveyor 14 side or to the mounting frame 1 side, for example.

[0016] In this way, by setting the height of the waste 13 clumps to a constant height, the subsequent estimation of the type and quantity of waste 13 using the hyperspectral camera 11 can be performed stably. The installation position and size of the leveling jig 16 are changed as appropriate depending on the belt conveyor 14 being used.

[0017] With the mounting frame 1 in place, the installation position, height, and orientation of the hyperspectral camera 11 are adjusted so that the entire width of the flat belt of the belt conveyor 14 (in the direction perpendicular to the conveying direction) fits within the field of view of the hyperspectral camera 11. The orientation, field of view, and focus of the hyperspectral camera 11 are adjusted while checking the image displayed on the monitor 18. The hyperspectral camera 11 and the monitor 18 are connected directly or indirectly via wired or wireless communication. By adjusting the field of view of the hyperspectral camera 11 in this way, it becomes possible to estimate the type and quantity of all the waste 13 being transported on the belt conveyor 14.

[0018] The height of the hyperspectral camera 11 can be adjusted using the height adjustment mechanism 19 of the mounting base 1. Specifically, by adjusting the length of the height adjustment mechanism 19, which is provided on the leg portion of the mounting base 1, the height of the upper surface of the mounting base 1 on which the hyperspectral camera 11 is mounted can be adjusted, thereby allowing the height of the hyperspectral camera 11 to be adjusted. Alternatively, instead of using the height adjustment mechanism 19, the height of the mounting base 1 itself may be adjusted.

[0019] In this configuration, the mounting base 1 consists of three stacked frame sections 10. However, instead of providing a height adjustment mechanism 19, the mounting height of the hyperspectral camera 11 may be adjusted by changing the number of stacked frame sections 10.

[0020] After the hyperspectral camera 11 has been adjusted, the halogen light 12 is shone onto the waste 13 being transported by the belt conveyor 14, and the type and quantity of the waste 13 are identified based on the reflected light from the waste 13. A blackout curtain 15 is hung on the mounting frame 1, blocking incoming light from outside such as sunlight, creating an environment where only halogen light from the halogen light 12 is shone onto the waste 13. The blackout curtain 15 is sized so that its ends reach a predetermined height from the flat belt surface of the belt conveyor 14.

[0021] Similarly, a blackout curtain 15 is placed over the hyperspectral camera 11. By placing the blackout curtain 15 over the hyperspectral camera 11, external light such as sunlight entering the camera lens can be blocked. As a result, the only light entering the camera lens of the hyperspectral camera 11 is the reflected halogen light from the halogen light 12, so the type and quantity of waste 13 can be reliably estimated.

[0022] Here, the halogen lights 12 are fixed to the upper surface of the mounting base 1 (the top of the frame section 10) directly above the belt conveyor 14, facing the belt conveyor 14. The halogen lights 12 have a rated luminous flux of 10,000 lm and are 110V / 500W earthquake-resistant halogen bulbs. A total of four halogen lights 12 are installed at the four corners of the upper surface of the mounting base 1, with their light-emitting surfaces facing the belt conveyor 14, but the number of lights installed is not limited to this. Furthermore, the halogen lights 12 are adjusted so that the light-emitting surface of the halogen lights irradiates the flat belt surface (horizontal plane) of the belt conveyor 14 at an angle of approximately 30° to 45°.

[0023] The waste materials 13 that flow along the conveyor belt are ultimately sorted by hand. The classification of the waste materials 13 sorted by hand is determined according to the acceptance conditions of the waste disposal facility, but for example, referring to the "Disaster Waste Treatment Guidelines" issued by the Ministry of the Environment, they are mainly divided into the following eight types (excluding the residue below the sieve). In other words, the waste materials 13 are sorted by hand into eight types: "wood scraps," "combustible materials," "non-combustible materials," "metal scraps," "concrete rubble," "separated soil," "recycled materials," and "recycled crushed stone."

[0024] Next, with reference to Figure 3, the estimation of waste 13 using the hyperspectral camera 11 will be explained. Halogen light emitted from the halogen light 12 is directed onto the waste 13 as it flows along the conveyor belt 14. The halogen light directed onto the waste 13 is reflected from the surface of the waste 13, and the reflected halogen light is incident on the hyperspectral camera 11.

[0025] The hyperspectral camera 11 can extract reflected light spectral data for each pixel of the captured image, allowing the type of waste 13 to be estimated from the extracted spectral characteristics. Furthermore, the amount of waste 13 can be estimated based on the number of pixels in the captured image that have the same or similar spectral characteristics. In other words, the area of ​​each type of waste 13 can be derived based on the set of pixels that have the same or similar spectral data, and the amount (volume) of each type of waste 13 can be estimated.

[0026] Here, the hyperspectral camera 11 is a type of camera that can finely analyze the wavelength components (spectrum) of light, and can measure the intensity of light at fine wavelength pitches (for example, 5 nm) for each pixel. Since the hyperspectral camera 11 is also a spectroscopic camera, the image captured by the hyperspectral camera includes wavelength information in addition to two-dimensional planar data in the x and y directions. An image with added wavelength information is called a data cube, and a data cube refers to an image in which two-dimensional planar images in the x and y directions are layered according to the spectrally separated wavelengths.

[0027] The hyperspectral camera 11 can acquire wavelength information for over 100,200 bands in its images. Therefore, compared to multispectral cameras and the like, the hyperspectral camera 11 can acquire a much larger amount of wavelength data, and the spectral characteristics are clearly displayed, resulting in a precise spectral pattern that allows for detailed analysis.

[0028] Since the resulting spectral pattern (intensity distribution of reflected light) differs depending on the type of waste 13 (e.g., disaster waste), if the spectral characteristics of the waste 13 can be extracted using the hyperspectral camera 11, the type of waste 13 can be estimated with high accuracy.

[0029] A spectrum is the distribution intensity of light (electromagnetic waves) at each wavelength, and can be represented (defined) as a two-dimensional graph with wavelength on the horizontal axis and intensity on the vertical axis. Furthermore, the representation of a spectrum is not limited to two-dimensional display; for example, it can be represented (defined) as a vector using SAM (Spectral Angle Mapper). In SAM, the target spectrum and the image spectrum are represented as vectors in an n-dimensional spectral space. Therefore, the smaller the angle (spectral angle) between these two vectors, the greater the similarity can be judged, and using this principle, it is possible to estimate the types of waste materials.

[0030] The waste 13 is leveled by a leveling jig 16 so that it forms a mass of a predetermined height from the surface on which the waste 13 is placed on the belt conveyor 14. The hyperspectral camera 11 and halogen light 12 are mounted at predetermined heights from the surface on which the waste 13 is placed. In this way, the distance between the hyperspectral camera 11 and the waste 13, and the distance between the halogen light 12 and the waste 13 are kept constant, so that the type of waste 13 can be reliably estimated. In the illustrated example, the distances from the flat belt surface of the belt conveyor 14 to the hyperspectral camera 11 and the halogen light 12 are equal, but these distances may be different. For example, the halogen light 12 may be positioned below the center of the frame section 10. In that case, the halogen light 12 is adjusted so that the inclination of the light-emitting surface is optimal with respect to the flat belt surface (horizontal plane) of the belt conveyor 14.

[0031] Using such a mounting frame 1, it becomes easy to estimate the type and quantity of waste 13, and to sort the waste 13 based on the estimated type and quantity, regardless of the location, such as an outdoor waste disposal site.

[0032] Next, a modified example of the mounting frame will be described with reference to Figure 4. This figure is a front view of the mounting frame 2 as seen from the front. The mounting frame 2 has a two-tiered structure consisting of a lower frame section 40 and an upper frame section 41. The lower frame section 40 is a wide frame section, and the upper frame section 41 is a narrower frame section than the lower frame section 40. In the mounting frame 2, the upper frame section 41 is stacked two levels high on top of the lower frame section 40.

[0033] The upper frame section 41 has a width approximately the same as the width of the belt conveyor 14. In contrast, the lower frame section 40 is wide enough to straddle the belt conveyor 14. The legs of the lower frame section 40 are provided with a height adjustment mechanism 42, which allows the overall height of the mounting base 2 to be adjusted. The upper frame section 41 may be attached to the lower frame section 40 by welding or the like. Alternatively, a detachable mechanism may be provided at the lower end of the legs of the upper frame section 41 so that the upper frame section 41 can be detachably attached to the lower frame section 40.

[0034] Referring to Figure 5, the structure of the frame section 10 (40, 41) will be described. The frame section 10 (40, 41) is composed of vertical frame members 21 and horizontal frame members 22. The frame section 10 has a structure in which four vertical frame members 21 are placed at the four corners, and four horizontal frame members 22 are placed at one end of the vertical frame members 21 so as to connect the vertical frame members 21 to each other. The frame section 10 is provided with diagonal braces on the sides to give it lateral strength. The vertical frame members 21 and horizontal frame members 22 are pipe-shaped (cylindrical) members, which helps to reduce weight.

[0035] Furthermore, the vertical frame member 21 may be extendable or retractable. If the vertical frame member 21 itself is extendable or retractable in this way, it is not necessary to provide the height adjustment mechanisms 19 and 42 described above. However, it is also possible to roughly adjust the height using the length of the vertical frame member 21 and then make fine adjustments using the height adjustment mechanisms 19 and 42.

[0036] Furthermore, an attachment mechanism for detachably attaching the height adjustment mechanism 19 may be provided at least one of the ends of the vertical frame member 21. In addition, a connecting mechanism may be provided at both ends of the vertical frame member 21 so that it can be used to connect with other frame members 10. By making the attachment mechanism and the connecting mechanism a common mechanism, the frame member 10 can be used for various purposes. For example, when the frame member 10 of the mounting base 1 is the lowest frame, the height adjustment mechanism 19 can be attached to one end and the other end can be used to connect with other frame members.

[0037] The vertical frame members 21 and horizontal frame members 22 are made of lightweight yet strong materials such as steel, aluminum, resin, and plastic, making it easy to move and carry the frame section 10.

[0038] The frame section 10 may also be an assembly-type component, where the vertical frame members 21 and horizontal frame members 22 are connected and assembled at the installation site. By using an assembly-type component in this way, it becomes even easier to move and transport.

[0039] Referring to Figure 6, other components of the frame section 10 (40, 41) will be described. The frame section 10 (40, 41) further includes a leg horizontal frame member 23. The leg horizontal frame member 23 is a frame member that is longer than the horizontal frame member 22 and is connected to the end of the vertical frame member 21. One example of a situation in which the frame section 10 having the leg horizontal frame member 23 can be used is as the lowest frame of the frame section 10 when the frame section 10 is placed directly on the frame of the belt conveyor 14. When the frame section 10 is placed directly on the belt conveyor 14, it is preferable that the leg horizontal frame member 23 be positioned perpendicular to the direction of transport of the waste 13 on the belt conveyor 14, but it may also be positioned parallel to the direction of transport of the waste 13.

[0040] As illustrated, by using the relatively long horizontal leg frame members 23 as the contact point between the lowest frame and the frame of the belt conveyor 14, the frame can be stably placed on top of the belt conveyor 14. Furthermore, because the length of the horizontal leg frame members 23 is longer than that of the horizontal frame members 22, it can accommodate belt conveyors 14 of various widths (sizes). For example, even when using multiple belt conveyors 14 side by side, the frame section 10 can be placed across the multiple belt conveyors 14. In this case, it is desirable that the frame section 10 be placed via a cushioning material to absorb vibrations so that vibrations from the belt conveyor 14 are not transmitted.

[0041] Referring to Figures 7 and 8, the configuration of the camera mounting section 30 will be described. The camera mounting section 30 includes a mounting base 31, a sliding mechanism 32 (first sliding mechanism), a frame 33, and a sliding mechanism 36 (second sliding mechanism).

[0042] The camera mounting section 30 is attached to the top of the frame section 10. A hyperspectral camera 11 is mounted on the camera mounting section 30. The camera mounting section 30 is a rectangular prism (cube) made up of horizontal and vertical rectangular members (prismatic members). The hyperspectral camera 11 is mounted in the space inside the camera mounting section 30 so that its lens faces the conveyor belt 14. A plate-like member 37 is attached to one of the four side surfaces of the camera mounting section 30. That is, the top, bottom, and side surfaces of the camera mounting section 30, which is made up of combined rectangular members, are open, but the side surface to which the plate-like member 37 is attached is closed. In this way, by providing the plate-like member 37 and closing one of the side surfaces, a space for mounting the hyperspectral camera 11 is secured.

[0043] The frame section 33 is a rectangular member composed of short-side members 34 and long-side members 35, on which the camera mounting section 30 and mounting base 31 are placed. The short-side members 34 are members that constitute the sides of the rectangular member that are shorter than the longer of the width and height of the frame section 10. The long-side members 35 are members that constitute the sides that are the same length as either the width or height of the frame section 10.

[0044] The short-side members 34 and the long-side members 35 are prism-shaped members (square timbers). The frame 33 is constructed by attaching the short-side members 34 to the lower ends of both ends of the long-side members 35 from below. In other words, the frame 33 is constructed by combining the short-side members 34 and the long-side members 35 in a grid pattern.

[0045] The mounting base 31 is placed on a first sliding mechanism 32 provided on the long side member 35 of the frame portion 33, and is slidable along the long side member 35. The presence of the sliding mechanism 32 allows the mounting base 31 to slide along the long side member 35. A sliding mechanism 36 is also provided on the short side member 34. The presence of the sliding mechanism 36 allows the camera mounting portion 30 to slide along the horizontal frame member 22.

[0046] As described above, by providing the sliding mechanisms 32 and 36, the camera mounting section 30 can be slid in the vertical and horizontal directions, making it possible to freely determine the position of the hyperspectral camera 11.

[0047] Next, a waste sorting and processing device will be described with reference to Figure 9. The waste sorting and processing device 100 is installed outdoors and is a device that estimates the type and amount of waste 13 transported by a belt conveyor 14 and sorts the waste 13. The waste sorting and processing device 100 has a sieving unit 101, an estimation unit 102, and a sorting unit 103. The sieving unit 101 sieves the waste 13 that is transported on the belt conveyor 14. First, at the waste treatment plant, the waste 13 is transported by transport vehicles to near the sieving unit 101. The transported waste 13 is temporarily placed in one place and then loaded onto an upstream belt conveyor separate from the belt conveyor 14 by a backhoe or the like, so that it is automatically fed from the belt conveyor 14 into the sieving unit 101. The fed-in waste 13 is sieved in the sieving unit 101.

[0048] In the sieving section 101, fine-grained waste 13 is sieved and removed, while relatively larger waste 13 is extracted and transported by the belt conveyor 14. As described above, the sieving section 101 is a machine such as a vibrating sieving machine or a rotary sieving machine, and the waste 13 is sieved using these machines. In the sieving section 101, small-sized waste 13 is removed, and relatively large-sized waste 13 is extracted and supplied to the belt conveyor 14. The sieved waste 13 supplied to the belt conveyor 14 is, for example, waste 13 of a size and weight that can be lifted by hand.

[0049] The estimation unit 102 uses a hyperspectral camera 11 to extract spectral data of the reflected light from the image captured by irradiating the sieved waste 13 with halogen light, and estimates the type of sieved waste 13 based on the extracted spectral data. The estimation of the type of waste 13 is performed based on the spectral characteristics of the reflected light from the halogen light, and the estimation of the quantity is performed based on the quantity of waste 13 transported by the flat belt and the proportion of each type. In the estimation unit 102, the hyperspectral camera 11 is installed in a predetermined position using mounting frames 1 and 2. The transport speed of the belt conveyor 14 is also controlled in accordance with the shutter speed of the hyperspectral camera 11.

[0050] The estimation of waste 13 in the estimation unit 102 is performed, for example, using machine learning by artificial intelligence (AI). Before transporting the hyperspectral camera 11 to the disposal site, the waste 13 generated at actual disposal sites is used to train the model and generate an estimation model for estimating waste 13. The machine learning by artificial intelligence is performed in advance at an experimental facility. Then, the estimation model generated in this way is brought to the disposal site and used to estimate the type of waste 13, making it possible to estimate the type and quantity of waste 13 with high accuracy. This makes it possible to estimate the amount of reusable materials, combustible materials, non-combustible materials, etc., and to adjust the acceptance status of the disposal site according to the type of waste 13.

[0051] The sorting unit 103 separates the sieved waste 13 and classifies it by type. Classification is performed, for example, by manual sorting. The sorted waste 13 is collected in sorting baskets or the like, which are determined for each type. The sorting unit 103 may be an industrial robot or the like that can automatically classify the waste 13 being transported on the belt conveyor 14 after obtaining the estimation results from the estimation unit 102.

[0052] The waste classification and processing device 100 may further include a matching unit. The matching unit compares the type and quantity of waste 13 classified by the classification unit 103 with the type and quantity of waste 13 estimated by the estimation unit 102. For example, the classification unit 103 can verify the type and quantity of waste 13 estimated by the estimation unit 102 by weighing the waste 13 collected in baskets for each type using a weighing device or the like.

[0053] According to this embodiment, waste materials such as garbage can be classified in detail. Furthermore, since a predetermined distance can be maintained between the hyperspectral camera and the waste, more accurate spectral analysis can be performed. In addition, by using a halogen light to irradiate the waste with halogen light of a specific wavelength, spectral analysis can be performed easily and accurately, allowing for precise estimation of the type and quantity of waste. Moreover, since the mounting frame is movable, it can be used in any outdoor location.

[0054] Although the present invention has been described above with reference to embodiments, the present invention is not limited to the embodiments described above and can be modified as appropriate. Various modifications can be made to the configuration and details of the present invention that can be understood by those skilled in the art within the scope of the present invention. Furthermore, any system or apparatus that combines the separate features included in each embodiment is also included in the scope of the present invention. For example, a hyperspectral camera may be used to estimate the type and amount of waste 13 in advance during temporary storage, and predictions may be made regarding the amount of work to be done thereafter. Alternatively, the classification unit 103 may be provided in a separate location to temporarily store the waste 13 that has passed through the estimation unit 102, and the sieving unit 101, estimation unit 102, and classification unit 103 may be provided in separate locations.
