Description

Technical Field

[0001] This invention relates to the field of textile processing machinery technology, and in particular to an intelligent clothing sorting, recycling and packaging device. Background Technology

[0002] With the continuous improvement of residents' living standards and the upgrading of textile consumption, the number of discarded clothes in society is increasing significantly year by year. The standardized recycling and resource utilization of discarded clothes has become an important part of green and low-carbon development. If discarded clothes are directly landfilled or incinerated as household waste, it will not only cause serious waste of textile resources such as cotton, linen, chemical fibers, and down, but their non-degradable components will also cause continuous pollution to the ecological environment such as soil and water. On the other hand, sorting, recycling, and reusing discarded clothes can effectively save textile raw materials, reduce production and processing energy consumption, and reduce solid waste pollution, thus having significant resource benefits and environmental value.

[0003] As an important component of urban public service facilities, used clothing recycling bins are a key link connecting residents' disposal of used clothing with professional recycling systems. Recycled clothing can be reused through refurbishment and reprocessing, and some intact garments can even be used to support remote areas, demonstrating significant social value. However, current used clothing recycling bins on the market still suffer from numerous technical shortcomings and functional defects, failing to meet the industry's development needs for the resource utilization of used clothing. Specific problems include: 1. Lack of automated sorting function: Existing recycling bins are only single storage boxes, which cannot identify and classify the material and type of waste clothing. All clothing is stored together, and a lot of manual labor is required for sorting. This not only results in low sorting efficiency and high labor costs, but also easily affects the recycling effect of waste clothing due to inaccurate sorting, thus reducing the value of resource recycling. 2. Lack of compression and packaging capabilities: The fluffy physical characteristics of clothing result in extremely low utilization of the storage space of recycling bins. The bins are easily filled quickly, and the lack of automatic compression function further exacerbates the problem of insufficient storage capacity. At the same time, existing equipment cannot achieve vacuum sealing and moisture-proof packaging after sorting. Clothes stored together are very susceptible to moisture, mold, and bacteria growth in humid environments, which not only damages the clothes and renders them unusable, but also produces odors and affects the public environment. 3. Lack of intelligent monitoring and reminder mechanism: There is a lack of real-time monitoring of the amount of clothing stored in the recycling bins. When the bins are full, reminders to urban management and recycling personnel cannot be sent in time. Clothes often pile up and overflow the bins, which not only affects the appearance of the city, but also prevents residents from disposing of their clothes properly, thus reducing the recycling efficiency of waste clothing. 4. Consumables require manual replenishment: Consumables for clothing in the recycling bins need to be checked and replaced manually at regular intervals. The lack of automated replenishment devices and the insufficient timeliness and accuracy of manual maintenance further increase the operating and management costs of the equipment.

[0004] The aforementioned problems mean that existing used clothing recycling bins can only provide simple clothing storage and cannot perform intelligent recycling and processing. This severely restricts the industrial development of resource utilization of used clothing and fails to meet the public service needs of modern urban green development. Therefore, developing an integrated clothing recycling device with intelligent identification and classification, adaptive compression, vacuum moisture-proof packaging, intelligent monitoring and transportation, and automatic consumable replacement is an urgent need to address the current pain points in the used clothing recycling industry and is of great significance for promoting the intelligent and standardized development of the used clothing recycling system.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example This embodiment discloses a specific implementation of an intelligent clothing sorting, recycling, and packaging device. This device is suitable for recycling waste clothing in outdoor / indoor public areas such as communities, business districts, and office buildings. It realizes full automation of the entire process of waste clothing from delivery, identification and sorting, graded compression, vacuum packaging to consumable replacement and finished product transportation. The following description is based on the overall structure of the device, the specific settings of each module, the workstation layout, and the complete workflow.

[0023] like Figure 2 and Figure 3 As shown, a smart clothing sorting, recycling and packaging device includes a delivery and identification module, a smart sorting module, a rotary storage module, a compression and packaging module, a discharge and conveying module, an automatic consumable replacement module, a data analysis and control system, and an electromechanical equipment maintenance port 3, all disposed in the outer casing.

[0024] The device sequentially includes a material receiving and sorting station 60, a longitudinal pre-compression station 61, a transverse final compression and packaging station 62, and a consumable replacement station 63 along the rotation path of the rotary storage module. These stations are spaced 90° apart in the circumferential direction, and the rotary storage module drives the sorting and recycling bins 5 through these stations in sequence.

[0025] like Figure 1 As shown, a used clothing deposit port 1 is provided on one side of the cabinet, a used clothing recycling port 2 is provided at the bottom, and an electromechanical equipment maintenance port 3 is provided below the used clothing deposit port 1. Inside the cabinet, a storage area 20 and a waste area 21 are provided at the corresponding consumable replacement workstation 63. Each module is electrically connected to the data analysis and control system, which realizes intelligent coordination and control of the entire process.

[0026] (a) Delivery and Identification Module like Figure 4 As shown, the delivery and identification module is a front-end supporting module of the receiving and sorting station 60, located on the upper part of the cabinet, including the used clothing delivery port 1, the industrial camera 12, and the used clothing conveyor belt 10; the industrial camera 12 is a high-definition vision camera, facing the delivery area of ​​the used clothing delivery port 1, used to detect clothing delivery behavior in real time, and when clothing is detected, it sends a trigger signal to the data analysis and control system. The used clothing conveyor belt 10 is a belt-type conveyor belt, which is inclinedly arranged between the used clothing inlet 1 and the receiving and sorting station 60. The drive motor of the used clothing conveyor belt 10 is electrically connected to the data analysis and control system. After receiving the trigger signal, it starts to transport the put-in clothing to the detection area of ​​the intelligent sorting module to complete the conveying and feeding of clothing.

[0027] (II) Intelligent Classification Module The near-infrared spectrometer fabric detection mechanism 11, located on the conveying path, is used to perform non-contact and rapid identification of clothing materials and output classification signals. Combined with the image recognition of the industrial camera 12, it can accurately determine the type and material of the clothing.

[0028] Near-infrared spectrometer collected the reflectance spectral sequence of clothing in the near-infrared band, x=[x1,x2,…,x…]. n ], serving as spectral fingerprint information for material identification, among which Let be the reflection intensity at the i-th wavelength point. To reduce the impact of clothing wrinkles, uneven thickness, stains, and changes in ambient light on the detection results, the data analysis system performs dark current subtraction and reference correction on the acquired spectral signals, and performs scattering correction and normalization preprocessing.

[0029] Normalization correction can be performed using the standard normal transformation (SNV), expressed as follows:

[0030] And further calculate the first-order difference To enhance the difference in absorption peaks; The data analysis system performs classification and identification based on preprocessed spectral features, and the classification model outputs the posterior probability of each material category. (where c is the material category), and the maximum posterior probability is used as the recognition confidence:

[0031] When the identification confidence level is lower than a preset threshold, the control system triggers secondary sampling or marks the garment as a blend / unknown category to reduce misclassification and improve system reliability. This can be achieved by sampling the same garment at multiple points and performing probability fusion. Let the number of samplings be m, then:

[0032] The classification model can adopt one of the following model structures in different implementations: (1) One-dimensional convolutional neural network (1D-CNN): The spectral sequence is taken as a one-dimensional signal input, and the local peak shape and band change trend of the spectrum are extracted through a one-dimensional convolutional layer. After noise reduction and dimensionality reduction by a pooling layer, the material category probability is finally output by the classification layer. , to achieve end-to-end recognition from spectral sequence to material category. (2) One-dimensional convolutional network with residual connection (1D-ResNet): Based on 1D-CNN, a residual connection structure is introduced to improve the deep feature extraction capability and reduce the risk of training degradation, thereby improving the stability and generalization ability of material category recognition under complex working conditions such as noise, wrinkles, and stacking. (3) Sequence classification model based on attention mechanism: The spectral sequence is mapped to the feature sequence and the correlation between different bands is learned through the attention mechanism. Scaling dot product attention is preferred, and its expression is:

[0033] Meanwhile, the industrial camera 12 is used to identify the type of clothing appearance and output the prior probability of the type. The prior probability and the probability of near-infrared spectral output A fusion decision is implemented to improve the accuracy of judgments under complex delivery conditions; the fusion decision is achieved as follows:

[0034] The fusion weight α is adaptively adjusted based on the confidence level:

[0035] in, , For the preset threshold, This is the amplitude limiting function.

[0036] This automatically increases the prior weight of the image when spectral recognition is unstable, and prioritizes the spectral results when spectral recognition is stable, thereby improving the overall recognition accuracy and robustness.

[0037] (III) Rotary Storage Module like Figure 5 and Figure 6 As shown, this module is the core of the device's workstation circulation, including multiple sorting and recycling bins 5 and a recycling bin rotation mechanism 15. The recycling bin rotation mechanism 15 includes a recycling bin rotating disk 16, a rotation mechanism fixing frame 17, and a rotation drive motor 18.

[0038] The recycling bin 5 is a rigid box structure with openings at the top and sides. The top has a snap-fit ​​groove for attaching the plastic box 7. Multiple recycling bins 5 are evenly arranged around the circumference of the recycling bin rotating disk 16. The recycling bin rotating disk 16 is a circular load-bearing turntable with a wear-resistant rotating bearing at the bottom, connected to the rotating mechanism fixing frame 17 to ensure stable rotation.

[0039] The rotary drive motor 18 is located on the side of the rotating mechanism fixed frame 17. After receiving the classification signal and workstation switching command from the data analysis and control system, it drives the recycling bin rotary disk 16 to rotate precisely, switching the corresponding category of recycling bin 5 to the designated workstation, and realizing precise feedback of workstation positioning through the position sensor.

[0040] (iv) Compression and Packaging Module This module is the core functional module of the device, including a longitudinal pre-compression mechanism 4, a transverse final compression mechanism 8, a sealing mechanism 14, and a vacuuming mechanism 13. The longitudinal pre-compression mechanism 4 is independently located above the longitudinal pre-compression station 61. The transverse final compression mechanism 8 and the sealing mechanism 14 are located on both sides of the transverse final compression and packaging station 62. The vacuuming mechanism 13 is located above the transverse final compression and packaging station 62, realizing adaptive graded compression, sealing separation, and vacuum moisture-proof packaging of clothing materials.

[0041] 1. Longitudinal pre-compression mechanism 4 like Figure 9 As shown, the system includes a longitudinal compression plate 36, a longitudinal drive motor 37, a pressure sensor, and a displacement sensor. The area of ​​the longitudinal compression plate 36 is smaller than the opening area of ​​the plastic box 7, and it only acts on the clothing in the compression bag inside the plastic box 7, without contacting the plastic box 7 body. Two vertically placed longitudinal drive motors 37 provide vertical driving force to the longitudinal compression plate 36. The pressure sensor and displacement sensor detect the compression force and the compression plate stroke, respectively, and the data are transmitted to the data analysis and control system in real time. After longitudinal compression, the spatial position sensor inside the sorting and recycling bin 5 detects the content of clothing inside. When the space of the sorting and recycling bin 5 is occupied to the horizontal compression line, the horizontal final compression mechanism 8 is activated to perform the final compression operation.

[0042] 2. Lateral final compression mechanism 8 like Figure 10 and Figure 11 As shown, it includes a lateral movement unit and a lateral compression unit.

[0043] The lateral movement unit includes a lateral fixed plate 38, lateral pressure slide rails 39, a lateral pressure rotating rod 40, and a lateral pressure slider 41. The lateral fixed plate 38 serves as the load-bearing structure of the entire unit and is fixedly connected to the outer shell. Two lateral pressure slide rails 39 are arranged parallel to each other on the lateral pressure fixed plate. The lateral pressure rotating rod 40 is located between the two lateral pressure slide rails 39 and has threads on it, with one end linked to the lateral pressure drive motor. The two ends of the lateral pressure slider 41 are slidably connected to the lateral pressure slide rails 39, and the middle part is threadedly connected to the lateral pressure rotating rod 40. When the lateral pressure drive motor rotates, the rotation of the lateral pressure rotating rod 40 drives the lateral pressure slider 41 to slide along the lateral pressure slide rails 39.

[0044] The transverse compression unit is positioned above the transverse compression slider 41 and includes a push rod support plate 42, a transverse compression plate 43, a compression plate push rod 44, a push rod secondary structure 45, a compression plate telescopic rod 46, and a compression plate push rod motor 47. A motor fixing plate 48 is located on the push rod support plate 42 near the transverse compression plate 43. The compression plate push rod motor 47 is fixed to the motor fixing plate 48, and its output shaft passes downwards through the motor fixing plate 48 and two sets of transmission mechanism fixing frames 49. A compression plate push rod 44 is sandwiched between each set of transmission mechanism fixing frames 49. The compression plate push rod 44 is parallel to the transverse fixing plate 38, and its output shaft is linked to one end of the compression plate push rod 44 via a push plate transmission mechanism. The other end of the compression plate push rod 44 is connected to one end of the push rod secondary structure 45 via a push rod connecting structure 50, and the other end of the push rod secondary structure 45 is hinged to the transverse compression plate 43.

[0045] Several sets of limiting structures 51 are also provided between the push rod support plate 42 and the transverse compression plate 43, including a telescopic rod provided on the push rod support plate 42 and a telescopic rod track provided on the transverse compression plate 43, with the telescopic rod and the telescopic rod track being compatible. When the compression plate push rod motor 47 rotates, it drives the compression plate push rod 44 to rotate in the horizontal plane, thereby pushing the transverse compression plate 43 to move towards the transverse final compression and packaging station 62. Under the restriction of the limiting structures 51, the transverse compression plate 43 squeezes the packaged recycled clothes placed in the sorting and recycling bin 5 from both sides, completing the final compression operation.

[0046] 3. Packaging mechanism 14 The compression bag sealing plate 56 is located at the top of the transverse compression plate 43 and includes a slide rail fixing plate 52, a sealing slide rail motor 53, a heat-sealing slide rail motor 54 mounted on the slide rail fixing plate 52, a compression bag sealing bracket 55, and a compression bag sealing plate 56. The slide rail fixing plate 52 is driven by the sealing movement motor to move along the top surface of the transverse compression plate 43. The compression bag sealing plate 56 is fixedly mounted at the front end of the compression bag sealing bracket 55, which is driven by the sealing slide rail motor to move along the top surface of the slide rail fixing plate 52. A miniature air pressure sensor is integrated on the compression bag sealing plate 56 to monitor the air pressure inside the bag.

[0047] A sealing slide rail motor drives the compression bag sealing plate 56 to move along the slide rail. A sealing movement motor, in conjunction with the drive slide rail fixing plate 52, moves along the slide rail, together completing the sealing of the compression bag at the transverse final compression and packaging station 62. The compression bag sealing plate 56 is an electrically heated plate structure. Driven by the sealing slide rail motor, the two sides of the compression bag sealing plate 56 approach and adhere, sealing the bag opening with heat and simultaneously sealing the bottom of the compression bag roll. Upon completion of the sealing, a blade separates the filled compression bag from the roll of compression bag material to be filled.

[0048] 4. Vacuum pumping mechanism 13 It includes a vacuum tube 57, a vacuum linear motor 58, and a vacuum linear slide rail 59. The vacuum linear motor 58 drives the vacuum tube 57 to move along the vacuum linear slide rail 59 to the opening of the compression bag, and works in conjunction with the transverse compression unit to complete the vacuuming operation at the transverse final compression and packaging station 62.

[0049] Both the longitudinal pre-compression mechanism 4 and the transverse final compression and sealing mechanism 14 utilize material identification results from a near-infrared spectrometer and an industrial camera 12 to dynamically adjust the operating parameters of subsequent compression mechanisms. The data analysis and control system has a built-in material-compression parameter database, which presets corresponding compression pressure ranges, compression speed ranges, target compression strokes, and holding time parameters for different clothing materials. When the intelligent classification module identifies the clothing material category, the control system calls the corresponding material parameter set as the initial control target and combines it with real-time sensor feedback to achieve adaptive adjustment. The compression pressure is calculated using the following formula: The formula for calculating compression pressure is: F is the output force of the compression actuator, and A is the effective force-bearing area of ​​the compression plate; The formula for calculating the compression stroke is: , To compress the thickness of the previous clothing stack, For target thickness; Or data analysis and control systems based on target volume ratio As a compression control target, based on the ratio of material type to target volume... Recommendation range determined With the corresponding pressure / speed settings.

[0050] Compression pressure and compression speed are not constant; a phased dynamic control logic is employed to balance efficiency and safety. The phased control includes at least four stages: (1) Rapid approach phase: The compression plate approaches the clothes in the compression bag at a high speed, and the compression pressure is limited to not exceeding the contact threshold. ; (2) Compaction stage: The compression pressure reaches the contact threshold. Then, the pressure is increased using a ramp method, and the pressure reference value is expressed as follows: k is the boost slope. To achieve the target final pressure for the corresponding material, the pushing speed of the compression plate is limited. (3) Pressure holding / thickness holding stage: The compression plate maintains the target pressure or target thickness for a period of time. This reduces the elasticity of clothing. (4) Vacuum Coordination Stage: Data analysis and control system combined with the bag pressure detected by miniature pressure sensor The compression plate advance speed and the working power of the vacuum mechanism 13 are dynamically adjusted to avoid air trapped inside the fiber, which could cause the compression bag to bulge or break.

[0051] During the vacuum coordination phase, the data analysis and control system adaptively adjusts the compression plate's advance speed according to the following formula:

[0052] in , These are the upper and lower limits of the compression plate's advance speed. The target air pressure inside the bag. For normalized interval parameters.

[0053] (v) Discharge and Conveying Module Includes a compression bag conveyor belt 9 and an old clothes recycling port 2 located below the horizontal final compression and packaging station 62. After the packaged clothes compression bag separates from the plastic box 7, it falls onto the compression bag conveyor belt 9, which transports it to the old clothes recycling port 2. The data analysis and control system collects storage information in real time and sends cleaning reminders to the management personnel.

[0054] (vi) Automatic Consumable Replacement Module like Figure 7 As shown, it includes a storage area 20, a waste area 21, a plastic box replacement mechanism 6, and a telescopic clamp 34. The plastic box replacement mechanism 6 is arranged above the consumable replacement station 63. The storage area 20 and the waste area 21 are located on both sides of the consumable replacement station 63. The storage area 20 is used to store plastic boxes 7 with pre-filled compression bags, and the waste area 21 stores empty plastic boxes 7 that are to be refilled with compression bags.

[0055] The plastic box 7 and the compression bag are embedded together. The compression bag is a long, straight cylindrical compression bag, which is embedded inside the plastic box 7. The compression bag has only one bottom. After the first final compression is completed, the heat sealing device will simultaneously heat seal the bottom of the separated new compression bag, thereby achieving the purpose of recycling.

[0056] The plastic box replacement mechanism 6 drives the retractable clamp 34 to grab the plastic box 7 with a bag from the storage area 20 and accurately install it onto the top of the recycling bin 5. The compressed bag is fixed inside the recycling bin along with the plastic box 7. When the compressed bag in a plastic box 7 is used up, the retractable clamp 34 grabs the empty plastic box 7 and recycles it to the waste area 21. After manual refilling of compressed bags, it can be reused. Each plastic box 7 can store 100 compressed bags, and the recycling bin can store 10 plastic boxes 7. Under normal usage, the compressed bags need to be replaced approximately once a month, without the need for frequent manual intervention.

[0057] like Figure 8As shown, the plastic box replacement mechanism 6 includes an inner slide rail 26, an inner slider 27, an outer slide rail 24, an outer slider, a middle slide rail 28, a middle slider 29, a clamp lifting motor 22, and a clamp telescopic mechanism. The inner slider 27 is slidably mounted on the inner slide rail 26, and the outer slider is slidably mounted on the outer slide rail 24, which is parallel and symmetrical to the inner slide rail 26. The middle slide rail 28 is positioned between the inner slider 27 and the outer slider and is perpendicular to both the inner slide rail 26 and the outer slide rail 24. The middle slider 29 is slidably mounted on the middle slide rail 28. The clamp lifting motor 22 is vertically fixed to the side of the middle slider 29, and the clamp telescopic mechanism is located at the output end of the clamp lifting motor 22. An inner slide rail drive motor 25 is provided on the side of the inner slide rail 26 to drive the inner slider 27 and the middle slide rail 28 to move along the inner slide rail 26. A limiter 30 is also provided at one end of the inner slide rail 26 to limit the farthest movement position of the inner slider 27. An intermediate slide rail drive motor 23 is provided on the outer slider, which is used to drive the intermediate slider 29 and the clamp lifting motor 22 to move along the intermediate slide rail 28.

[0058] The clamp telescopic mechanism includes a telescopic clamp 34, a telescopic fixing member 19, a clamp telescopic motor 33, a clamp drive gear 32, and a clamp linear gear 31. The specific connection structure is as follows: The telescopic clamp 34 consists of a pair of symmetrically arranged jaws, and the bottom of the jaws is provided with two outwardly protruding clamping feet 35, which facilitates lifting the bottom of the plastic box 7.

[0059] The telescopic fixing component is located below the clamp lifting motor 22, and its top end is connected to the output end of the clamp lifting motor 22. It has an elongated slot inside for placing the clamp drive gear 32 and the clamp linear gear 31, and open slots are formed on both sides for the clamp to extend and retract.

[0060] The clamp telescopic motor 33 is fixed to the bottom of the telescopic fixing member, and the output end of the clamp telescopic motor 33 passes upward through the telescopic fixing member, and the end is connected to the clamp drive gear 32 for transmission.

[0061] The clamp drive gear 32 meshes with the middle part of the clamp linear gear 31, and the two ends of the clamp linear gear 31 are respectively connected to the gripper. When the clamp telescopic motor 33 is started, the clamp drive gear 32 drives the clamp linear gear 31 to rotate, thereby driving the gripper to extend or retract.

[0062] The retractable gripper opens and closes by driving the gear meshing transmission through the clamp telescopic motor 33. Through the sliding cooperation of the inner slide rail 26, the outer slide rail 24, and the middle slide rail 28, and the drive of the clamp lifting motor 22, the precise gripping and installation of the plastic box 7 with bag and the gripping and recycling of the empty plastic box 7 are completed at the consumable replacement station 63.

[0063] (vii) The data analysis and control system is electrically connected to each module to realize intelligent control of the entire process of signal reception, data processing, motion control, workstation switching command sending and information feedback.

[0064] (viii) The mechanical and electronic equipment inspection port 3 is located below the old clothes inlet 1 and is used for the daily inspection and maintenance of the device.

[0065] This device uses a consumables replacement station 63 → material receiving and sorting station 60 → longitudinal pre-compression station 61 → transverse final compression and packaging station 62 → consumables replacement station 63 as the core station flow loop. The entire process is uniformly controlled by a data analysis and control system. Figure 12 As shown, the working process is as follows: Empty recycling bin 5 is moved to consumable replacement station 63. Plastic box replacement mechanism 6 drives telescopic clamp 34 to grab a bagged plastic box 7 from storage area 20 and precisely attach it to the top of the recycling bin. After boxing, the recycling bin moves to receiving and sorting station 60 to stand by. After a user deposits clothing, industrial camera 12 detects the deposit and triggers the old clothing conveyor belt 10 to start, transporting the clothing to the intelligent sorting module's detection area for material identification.

[0066] According to the classification signal, the rotary drive mechanism rotates the recycling bin with the corresponding bagged plastic box 7 to the receiving and sorting station 60. The clothes fall precisely into the compression bag inside the plastic box 7 through the conveyor belt discharge port. After receiving, the recycling bin rotates to the longitudinal pre-compression station 61. The longitudinal pre-compression mechanism 4 performs adaptive preliminary compression on the clothes in the compression bag according to the corresponding material compression parameters. If the amount of clothes does not meet the packaging conditions after compression, the recycling bin returns to the receiving and sorting station 60 to continue receiving. After meeting the conditions, it rotates to the transverse final compression and packaging station 62.

[0067] The transverse final compression mechanism 8 performs final compression and pressure maintenance on the garments, simultaneously activating the compression bag sealing plate 56 to complete the heat sealing of the compression bag and separating the filled compression bag from the compression bag roll material. The vacuum pumping mechanism 13's vacuum tube 57 connects to the compression bag opening. The system dynamically coordinates the compression plate's advance speed with the power of the vacuum pumping mechanism 13 to prevent air from being rapidly compressed and trapped within the fibers, causing bulging or damage. After reaching the preset vacuum level, the moisture-proof packaging is completed, and the vacuum tube 57 resets.

[0068] The horizontal compression plate 43 is reset, and the packaged finished product falls to the compression bag conveyor belt 9 below the workstation under the action of gravity. The conveyor belt transports the finished product to the finished product recycling port. When the storage volume in the recycling port reaches the standard, the system sends a cleaning reminder to the management personnel.

[0069] After the packaging is completed, the sorting and recycling bin 5 is transferred to the consumables replacement station 63. The clamp grabs the empty plastic box 7 from the top of the bin and puts it into the waste area 21. Then, it grabs a new bagged plastic box 7 from the storage area 20 to complete the installation. The sorting and recycling bin 5 returns to the receiving and sorting station 60 to start the next work cycle. The staff regularly open the storage area 20 to refill the new bagged plastic box 7 and clean the empty plastic box 7 in the waste area 21 to complete the consumables cycle replenishment.
