Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0034] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0035] FIG. 1 is a diagram showing the schematic configuration of a waste treatment system according to one embodiment of the present invention.

[0036] Referring to FIG. 1, a waste treatment system (10) according to one embodiment of the present invention includes a waste treatment device (100), a weight measuring unit (200), a weighing sensor unit (300), a waste analysis unit (400), and a treatment information generation unit (500).

[0037] The waste treatment device (100) is a device in which waste is input from a user, and internally, the weight measurement, material analysis, and calculation of treatment costs are performed in conjunction, and is implemented as a system structure in which each function is integrated.

[0038] The weight measuring unit (200) is configured to quantitatively measure the weight of waste introduced into the waste treatment device (100) and may be composed of sensor modules such as a load sensor, a pressure sensor, or a load cell, and the weight information obtained therefrom is used as reference information necessary for material analysis and settlement.

[0039] The weighing sensor unit (300) is configured to perform a detection operation for material identification on waste that has passed through the weighing unit (200), and includes at least one type of detection sensor, and such sensor analyzes the physical and chemical characteristics of the waste in real time and provides material information of the waste.

[0040] The waste analysis unit (400) is configured to finally determine the material of the waste by combining and analyzing the weight information of the waste obtained from the weight measurement unit (200) and the material detection information obtained from the weighing sensor unit (300), and may include a data fusion algorithm or pattern analysis logic.

[0041] The processing information generation unit (500) is configured to automatically calculate the total processing cost of the waste based on the material information and weight information calculated by the waste analysis unit (400) and to generate settlement information that can be provided to the user, and can perform output and storage functions by linking a display, a network transmission device, a data storage device, etc.

[0042] A waste treatment system (10) according to one embodiment of the present invention having the configuration described above can improve the fairness and efficiency of settlement by accurately calculating the treatment cost by simultaneously considering the material and weight of the waste, and provides a technical effect that enables high-precision waste classification and cost estimation without human intervention through automated detection and analysis functions.

[0044] FIG. 2 is a drawing showing a metering sensor unit of a waste treatment system according to one embodiment of the present invention.

[0045] Referring to FIG. 2, the metering sensor unit (300) includes at least one of a near-infrared sensor (310), an X-ray fluorescence analyzer (320), an image analysis sensor (330), an electrical conductivity sensor (340), a dielectric constant sensor (350), a heat sensor (360), and a gas sensor (370).

[0046] The near-infrared sensor (310) is used to classify waste by utilizing the difference in reflectance inherent to the material by detecting a near-infrared spectrum of a specific wavelength reflected from the surface of the waste, and is particularly effectively used to distinguish non-metallic materials such as plastics, fibers, and paper.

[0047] The X-ray fluorescence analyzer (320) is configured to irradiate metal waste with X-rays and analyze the reflected fluorescence spectrum to determine the elemental composition or content of the metal, and enables the identification of various metal materials such as aluminum, copper, iron, and stainless steel.

[0048] The image analysis sensor (330) is configured to acquire external information such as the color, surface texture, and shape of waste through an RGB or multispectral camera, and to classify the material of irregular waste through this information, thereby enhancing the visual-based classification function.

[0049] The electrical conductivity sensor (340) and the dielectric constant sensor (350) detect differences in current conductivity and dielectric properties, respectively, thereby enabling the distinction between metals and non-conductive materials, and are particularly effective for the primary classification of electronic waste or composite waste.

[0050] The thermal sensor (360) detects the surface temperature and radiant heat response of the waste and estimates the type of waste through differences in heat transfer characteristics by material, and is configured to enable non-contact detection by utilizing an infrared temperature sensor.

[0051] The gas sensor (370) is configured to detect volatile organic compounds (VOCs) or gases such as methane and ammonia generated from specific organic materials or biodegradable waste, and to identify the material based on the biological decomposition potential of the waste.

[0052] A metering sensor unit (300) according to one embodiment of the present invention having the configuration described above can collect complex sensor information based on physical, chemical, electrical, thermal, and biological characteristics, and perform high-precision waste material analysis based thereon, thereby providing high detection precision and classification efficiency in an automated and unmanned waste classification system.

[0054] A metering sensor unit (300) according to one embodiment of the present invention having the configuration as described above includes an integrated analysis algorithm (380) that fuses and analyzes waste material-related data obtained from at least two of an image analysis sensor (330), a near-infrared sensor (310), an X-ray fluorescence analyzer (320), an electrical conductivity sensor (340), a dielectric constant sensor (350), a thermal sensor (360), and a gas sensor (370).

[0055] The integrated analysis algorithm (380) performs the function of analyzing the correlation between data obtained from the plurality of sensors, assigning weights to each detection result according to the material classification criteria and reliability index pre-set for each sensor, and then deriving a final material determination value through an integrated judgment function to which the weights are applied.

[0056] The integrated analysis algorithm (380) first analyzes the external characteristics of waste based on color, shape, and texture information obtained through the image analysis sensor (330), and further combines spectral reflectance and elemental composition data obtained from the near-infrared sensor (310) and the X-ray fluorescence analyzer (320) to improve physical and chemical precision, and distinguishes the material by reflecting the electrical characteristics of the electrical conductivity sensor (340) and the dielectric constant sensor (350).

[0057] In addition, by considering the thermal response information obtained through the thermal sensor (360) and the gas concentration information of organic or biodegradable waste detected through the gas sensor (370), the accuracy of identification of composite material waste can be improved.

[0058] The above integrated analysis algorithm (380) is configured to minimize the possibility of errors caused by detection interference between specific materials or foreign substance contamination by applying dynamic weights that reflect various factors such as real-time environmental conditions, measurement reliability, and past material classification history for the data of each sensor.

[0059] A weighing sensor unit (300) according to one embodiment of the present invention having the configuration described above does not simply process multiple sensor information in parallel, but maximizes detection accuracy through a data fusion-based analysis algorithm, and in particular enables precise classification of waste that is similar in appearance or made of composite materials, thereby providing a technical effect that significantly improves waste treatment efficiency and automation levels.

[0061] A metering sensor unit (300) according to one embodiment of the present invention having the configuration as described above includes an integrated analysis algorithm (380) that fuses and analyzes waste material-related data obtained from at least two of an image analysis sensor (330), a near-infrared sensor (310), an X-ray fluorescence analyzer (320), an electrical conductivity sensor (340), a dielectric constant sensor (350), a thermal sensor (360), and a gas sensor (370).

[0062] The integrated analysis algorithm (380) is configured to perform accurate identification of waste materials by integrating and analyzing data input from multiple sensors through a multi-stage procedure.

[0063] The integrated analysis algorithm (380) first analyzes the external characteristics of the waste based on color, shape, and texture information obtained through the image analysis sensor (330) to derive a primary material candidate group.

[0064] This visual information is advantageous for quickly identifying the external characteristics of waste and can be utilized to determine identification priorities among complex waste.

[0065] Next, precision correction for the primary candidate group is performed by integrating and analyzing the spectral reflectance and elemental composition information obtained from the near-infrared sensor (310) and the X-ray fluorescence analyzer (320). Spectral information is based on the intrinsic wavelength response of the material, and the elemental composition data from the X-ray fluorescence analyzer improves accuracy for metallic materials.

[0066] In addition, based on the electrical characteristic values ​​detected through the electrical conductivity sensor (340) and the dielectric constant sensor (350), it is determined whether the waste is a conductive material, thereby making it easy to distinguish between metals and non-metals.

[0067] This information is particularly useful for objects composed of multiple materials, such as electronic waste.

[0068] Next, by analyzing the thermal reaction information and volatile gas generation patterns measured through the heat sensor (360) and gas sensor (370), the presence of organic material or biodegradable waste is determined complementarily.

[0069] For example, biological waste emits methane, ammonia, etc. under specific conditions, and these characteristics, when combined with other sensor information, enhance judgment accuracy.

[0070] Finally, the integrated analysis algorithm (380) calculates weights based on predefined material classification criteria, detection reliability per sensor, measurement environment conditions, and waste classification history information for the detection results of each sensor.

[0071] These weights are set by comprehensively reflecting the reliability, precision, and application priority of each data point.

[0072] The calculated weights are reflected in the detection results and are finally applied to the integrated judgment function to calculate the material identification value.

[0073] This allows analysis results based on multiple sensors to be quantified according to a single judgment criterion, minimizing the possibility of misclassification even in cases of mixed waste or high contamination levels.

[0074] A metering sensor unit (300) according to one embodiment of the present invention having the configuration described above provides a technical effect that can significantly improve the automation precision and processing efficiency of material classification by integrating heterogeneous data provided by each sensor and utilizing environment-adaptive weights and quantified analysis logic.

[0076] FIG. 3 is a diagram showing the schematic configuration of a waste treatment system according to another embodiment of the present invention.

[0077] Referring to FIG. 3, a waste treatment system (20) according to another embodiment of the present invention includes a waste treatment device (100), a weight measuring unit (200), a weighing sensor unit (300), a waste analysis unit (400), a treatment information generation unit (500), and a waste washing device (600).

[0078] Here, the waste treatment device (100), weight measurement unit (200), weighing sensor unit (300), waste analysis unit (400), and processing information generation unit (500) are identical to the components of FIG. 1, so their descriptions are omitted to avoid duplication of descriptions.

[0079] The waste washing device (600) is configured to perform washing by spraying washing water to remove foreign substances, foreign particles, harmful substances, etc. attached to the surface of waste flowing into the waste treatment device (100), and is applied to improve the accuracy of waste analysis and the reliability of settlement results.

[0080] The waste washing device (600) can be installed in the initial or intermediate stage of the waste treatment process and, in particular, is positioned in front of the material recognition sensor to perform the function of preventing sensor surface contamination and reducing the detection error rate.

[0081] In addition, the wash water can be sprayed at an appropriate pressure through a pressure regulating valve or pump, and various nozzle structures such as rotary, cross, and precision spraying can be applied depending on the type of waste.

[0082] A waste washing device (600) according to one embodiment of the present invention having the configuration described above provides a technical effect that can improve the reliability and durability of the entire system by cleaning the appearance and surface condition of the waste, thereby increasing the recognition accuracy of the detection sensor and significantly reducing the possibility of errors in material identification, while reducing the maintenance cycle of the sensor.

[0084] Figure 4 is a diagram showing the schematic configuration of the waste washing device of Figure 3.

[0085] Referring to FIG. 4, the waste washing device (600) includes a hopper (610), an inlet (620), a ring seating groove (630), a rotating ring (640), a ring driving unit (650), and a plurality of washing water spraying units (660).

[0086] The hopper (610) is a component installed to temporarily receive waste supplied to the waste treatment device (100) and to drop it toward the lower conveying device (670), and performs the function of controlling the amount of waste flowing in and discharging it at regular intervals.

[0087] The input port (620) is installed upright on the lower side of the hopper (610) to form a path for dropping waste discharged from the hopper (610) downward and transferring it to the conveying device (670).

[0088] This configuration maintains a constant direction of waste fall and ensures that the washing and detection processes are performed stably.

[0089] The ring seating groove (630) is a circular groove structure formed along the inward surface of the input port (620) and serves as a guide and support to allow the rotating ring (640) to rotate.

[0090] This enables smooth rotation of the rotating ring and accurate position maintenance.

[0091] The rotating ring (640) is formed in the shape of a circular ring and is rotatably installed in the ring seating groove (630), and rotates in the circumferential direction while supporting the washing water spraying part (660), thereby ensuring that washing water reaches the entire surface of the waste uniformly.

[0092] The ring drive unit (650) is connected to the rotating ring (640) and rotates the rotating ring (640) at a constant speed through a motor, gear, or chain drive method, and functions to control the distribution of the cleaning water spray and maximize cleaning efficiency.

[0093] A plurality of washing water spraying units (660) are spaced apart at regular intervals on the circumference of the rotating ring (640) and spray washing water at various angles on the outer surface of waste falling along the inlet (620). Each spraying unit is composed of a high-pressure nozzle, a spray nozzle, or a pulse spray nozzle, etc., to remove foreign substances from the waste and improve the accuracy of material detection.

[0094] A waste washing device (600) according to one embodiment of the present invention having the configuration described above provides the effect of improving the reliability of the entire waste analysis system by efficiently removing foreign substances during the waste input stage, thereby increasing the detection accuracy of the subsequent sensor unit and maintaining a uniform state of the waste surface.

[0096] Figure 5 is a drawing showing the structure of the rotating ring of Figure 4 in detail.

[0097] Referring to FIG. 5, the rotating ring (640) includes a ring body (641), a guide ring (642), a guide groove (643), and a ring inward surface (644).

[0098] The ring body (641) is a structure that is rotatably positioned in the ring seating groove (630), forms the basic circular frame of the rotating ring (640), and is a main structure that supports and fixes a plurality of washing water spraying parts (660).

[0099] The ring body (641) is manufactured with a precision-machined circular structure, minimizes frictional resistance on the inner and outer surfaces to ensure rotational stability, and performs a center alignment function to reduce deviation in the spray position of the cleaning water.

[0100] The guide ring (642) is fixedly installed along the upper side of the ring seating groove (630) to prevent the ring body (641) from being lifted upward or detached while rotating, and functions as a guide structure for stable rotation of the ring body.

[0101] The guide groove (643) is formed extending along the upper side of the ring body (641) and is formed in a structure that physically engages with the guide ring (642), and serves to prevent the ring body from separating from the ring seating groove (630) or shifting its position.

[0102] This prevents the risk of detachment that may occur during high-speed rotation and ensures the repeatability of the cleaning spray position.

[0103] The ring inward surface (644) is a surface exposed from the ring seating groove (630) among the inner surfaces of the ring body (641), and is formed as a rounded curved surface having curvature.

[0104] This curved surface structure provides the basis for a curved path that guides the washing water sprayer (660) to move in an up-and-down curved motion.

[0105] In addition, the inner surface of the ring (644) is machined to perform both driving and guiding functions of the injection part, and by absorbing vibrations generated during movement and dispersing rotational loads, it is possible to minimize wear and error accumulation due to long-term operation.

[0106] A rotating ring (640) according to one embodiment of the present invention having the configuration described above maintains the rotational cleaning function of the spraying unit with high precision and ensures uniform spraying regardless of the position and direction of the waste to be cleaned, thereby providing a technical effect that maximizes the efficiency of removing residue from the surface of waste and the accuracy of material detection.

[0108] Figures 6 and 7 are drawings showing the configuration of a cleaning water spray unit installed within the rotating ring of Figure 5.

[0109] Referring to FIGS. 6 and 7, the washing water spraying unit (660) includes a curved moving groove (661), a body part (662), a guide bar (663), a body support spring (664), a spray nozzle (665), a protrusion (666), and a driving cam (667).

[0110] The curved moving groove (661) is a groove structure formed to extend in a curved shape in the up-and-down direction along the ring inward surface (644), providing a path so that the body part (662) can move up and down stably along a certain curvature.

[0111] This groove is designed to enable constant cleaning spray position control even during rotational movement.

[0112] The body part (662) is connected to the curved moving groove (661) and configured to be able to reciprocate in the up and down direction by the rotational driving force of the driving cam (667), and a spray nozzle (665) is installed at the front end and a protrusion (666) is installed at the rear end.

[0113] The body moves along a curved path and is capable of spraying cleaning water at various locations on the waste.

[0114] The guide bar (663) is installed on the upper side of the curved moving groove (661) and is connected by penetrating the body part (662) in the vertical direction, thereby precisely guiding the movement path of the body part.

[0115] Ensures the repeatability of the wash water spray position.

[0116] In particular, by having a structure bent to correspond to the curvature of the curved moving groove (661), twisting or warping is prevented during curved movement.

[0117] The body support spring (664) is installed on the lower side of the curved moving groove (661) to support the body part (662) upward and provides an elastic restoring force to return the body part, which has been lowered by the driving cam (667), to its original position.

[0118] This contributes to ensuring the continuity of the cleaning spray and alignment with the cam operation cycle.

[0119] The spray nozzle (665) is installed at the front end of the body part (662) and is configured to spray high-pressure washing water in the direction of movement of the waste, and the angle and spray pattern of the nozzle can be adjusted according to the size and shape of the waste.

[0120] This enables uniform spraying onto the surface of the waste.

[0121] The protrusion (666) is formed at the rear end of the body part (662) and, by contacting the drive cam (667), receives downward movement force from the rotational drive into the body part and performs a downward movement.

[0122] The driving cam (667) is rotatably installed on the inner side of the ring body (641) and is seated on the protrusion (666), and operates in a structure that repeatedly pushes the body part (662) downward according to its rotation.

[0123] The drive cam sequentially changes the spray position through rotation at a constant cycle, which enables cleaning of various sides of the entire waste.

[0124] A cleaning water spraying unit (660) according to one embodiment of the present invention having the configuration described above can perform three-dimensional and precise cleaning on the surface of waste through a plurality of spraying units capable of individually moving up and down within a rotating ring, and can simultaneously achieve technical effects such as improved sensor detection accuracy, increased efficiency in removing foreign substances, and maintenance of device durability.

[0126] A washing water spraying unit (660) according to one embodiment of the present invention having the configuration as described above may further include a cam driving unit (668).

[0127] The cam drive unit (668) is a drive mechanism for rotating a plurality of drive cams (667) in a synchronized manner, and by controlling each cam to rotate at the same timing rather than operating independently, it maintains the overall spraying timing and movement of the cleaning water spray unit (660) consistently.

[0128] The cam drive unit (668) may include a plurality of drive shafts (6681), a universal joint (6682), and a shaft drive unit (6683).

[0129] The drive shaft (6681) is configured to be arranged in a polygonal shape or circular arrangement along the inner side of the ring body (641) and coupled to each drive cam (667), and is an intermediate transmission means that directly transmits rotational force to the cam.

[0130] The universal joint (6682) connects two adjacent drive shafts (6681), transmits rotational power without loss, and enables smooth synchronous driving even when the rotation axis is not constant.

[0131] This performs the function of compensating so that the cams operate identically even if there are deviations in rotation angle or position.

[0132] The shaft drive unit (6683) is a rotary drive source installed by being coupled to one of the plurality of drive shafts (6681), and may be composed of a motor, a gearbox, or a rotary actuator, and serves to transmit rotational force to the entire cam drive system.

[0133] This drive unit controls the reference timing of the entire cam rotation and serves as an important foundation for precisely controlling the wash water spraying operation.

[0134] A cam drive unit (668) according to one embodiment of the present invention having the configuration described above provides a technical effect that can improve the cleaning performance and reproducibility of the entire system by accurately synchronizing and rotating a plurality of drive cams, thereby precisely controlling the vertical movement of each cleaning water spray unit, maintaining the timing and interval of the cleaning spray consistently.

[0136] FIG. 8 is a drawing showing the specific configuration of a cam drive unit according to the present invention.

[0137] Referring to FIG. 8, the cam drive unit (668) includes a plurality of drive shafts (6681), a plurality of universal joints (6682), and a shaft drive unit (6683).

[0138] The drive shaft (6681) is arranged along the inner side of the ring body (641) and is arranged in a polygonal shape having a number of sides corresponding to the number of drive cams (667), so that each drive shaft corresponds to each drive cam (667).

[0139] Each drive shaft is rotatably supported around a fixed central axis and serves as a rotating shaft that transmits power in a one-to-one correspondence with each cam.

[0140] The universal joint (6682) connects two adjacent drive shafts (6681), continuously transmits rotational driving force, and controls each cam to operate at the same rotational speed and timing by compensating for rotational deviations caused by differences in installation position or angle.

[0141] The configuration of such a universal joint is advantageous for ensuring rotational alignment in polygonally arranged rotating bodies.

[0142] The shaft drive unit (6683) is connected to and installed on one of the plurality of drive shafts (6681) and is configured in the form of an electric motor, a gear module, or a rotary actuator, and supplies rotational power to the entire cam drive unit through the selected drive shaft.

[0143] The shaft drive unit acts as a prime mover that sets the reference operation for the entire drive series, and can precisely control the rotation period and timing in conjunction with sensors or control devices.

[0144] A cam drive unit (668) according to one embodiment of the present invention having the configuration described above ensures precise synchronous rotation of the drive cams and enables the vertical movement of each cleaning water spray unit (660) to be performed consistently, and flexibly absorbs positional deviations, rotational delays, etc. that may occur during rotation, thereby providing a technical effect of improving the cleaning repeatability and durability of the entire device.
