Description

Technical Field

[0001] The present invention relates to the field of recycling of recyclable materials, and in particular to a recycling sorting line and a sorting method for recycling recyclable materials. Background Art

[0002] The types and quantities of recyclables generated in daily life are increasing, and the time and monetary costs of recycling solely relying on manpower are also increasing; how to quickly, accurately and efficiently sort and recycle these recyclables has become a difficult problem that needs to be solved urgently.

[0003] Since the sorting of recyclables for resource utilization is the back-end link of the recyclables processing process, it is subject to the front-end conditions of recycling. If recyclables can be put in a standardized manner and correctly classified, the efficiency of sorting for resource utilization of recyclables will be improved accordingly. However, at present, residents put various types of recyclables in one recycling bag, which needs to be unpacked and sorted in the back-end sorting link. At present, manual bag unpacking is replaced by machine bag breaking to increase production. Specifically, reference may be made to the Chinese invention patent publication with publication number "CN116853709A" which records an intelligent AI garbage automatic collection device and method, which includes a frame and a bag breaking mechanism installed on the frame, the bag breaking mechanism including a temporary storage plate, bag breaking teeth and a driving member, the temporary storage plate is slidably connected to the frame, the tooth tips of the bag breaking teeth face upward and protrude from the temporary storage plate, the bag breaking teeth are fixedly connected to the end of the temporary storage plate, the driving member is installed on the frame, and the driving member is used to drive the temporary storage plate to slide on the frame; a bag collecting mechanism, the bag collecting mechanism is located above the bag breaking mechanism, the bag collecting mechanism includes a fixed frame, a rubber-coated roller and a rotating drive source, the fixed frame is slidably connected to the frame, the rotating drive source is installed on the fixed frame, the output shaft of the rotating drive source is coaxially and fixedly connected to the rubber-coated roller, and the rubber-coated roller is rotatably connected to the fixed frame.

[0004] The bag breaking mechanism in the above existing solutions is too complicated and more difficult to clean. Summary of the invention

[0005] In order to solve the above problems, the first purpose of the present invention is to provide a recyclable resource utilization sorting line, which has the advantages of streamlined structure, unchanged functions, less recyclable residue, more convenient cleaning and lower cost.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] A recyclable resource utilization sorting line comprises a broken bag recovery box and a conveyor belt for delivering bagged recyclables to a delivery port of the broken bag recovery box; the broken bag recovery box comprises a bag collecting mechanism and a bag breaking mechanism installed on a frame inside the box body, the bag collecting mechanism moves a device arranged above the bag breaking mechanism for rolling up empty recyclable bags and transferring them to the top of an empty bag recovery bin; it is characterized in that: the bag breaking mechanism comprises a pull-out platform arranged below the delivery port for transverse movement, a scraper assembly arranged above the pull-out platform, and a bag breaking blade assembly arranged below the pull-out platform; the lower end face of the scraper assembly is fitted on the upper end face of the pull-out platform, the pull-out platform is provided with a through hole on the front side of the scraper assembly, and a scraper is arranged on the bag breaking blade assembly; the scraper can extend upward from the through hole to the pull-out platform.

[0008] The present invention adopts the above-mentioned technical solution, which relates to a recyclable resource utilization sorting line. The difference from the prior art is that the bag breaking mechanism in the recyclable resource utilization sorting line adopts a pull-out platform as a receiving platform below the delivery port, which is used to receive the recycling bag placed in the delivery port. In addition, a bag breaking blade assembly is arranged below the pull-out platform, and the scraper of the bag breaking blade assembly is movably arranged and can be extended or pushed into the through hole on the pull-out platform. In this way, when the scraper extends upward from the through hole to the pull-out platform, the recycling bag can be cut at this time, so that the recyclables inside the recycling bag are scattered on the pull-out platform, and then the scraper withdraws from the through hole. Finally, based on the relative movement of the pull-out platform and the scraper assembly, the scraper assembly pushes the recyclables on the pull-out platform into the recycling bin.

[0009] Based on the above scheme, the bag breaking mechanism in the recyclable resource utilization sorting line has a streamlined structure and unchanged functions, resulting in less recyclable residue, easier cleaning and lower costs.

[0010] Preferably, the bag-breaking blade assembly is fixedly connected to the bottom of the drawer platform, and the bag-breaking blade assembly moves laterally with the drawer platform. In this way, it can be ensured that the scraper in the bag-breaking blade assembly is always aligned and synchronized with the through hole of the drawer platform. On the other hand, during the bag-breaking process, the bag-breaking blade assembly can be used to move laterally synchronously with the drawer platform to break the bag.

[0011] Preferably, the pull-out platform includes a tray body and baffles disposed on the left and right sides of the tray body; the middle portion of the scraper assembly is constructed as a protrusion adapted to the tray body and the baffles on both sides. In this solution, the baffles on both sides can ensure that the recyclables will not fall from both sides or get stuck in the moving track of the pull-out platform.

[0012] In a specific embodiment, the bag breaking blade assembly includes a rotating shaft positioned by a bearing group, a plurality of scrapers arranged on the rotating shaft, and a scraper driving motor driving the rotating shaft and the plurality of scrapers thereon to rotate; the scraper driving motor drives the rotating shaft and the plurality of scrapers thereon to rotate in a path where the plurality of scrapers can extend out of or retract into the through hole. In this solution, the scraper driving motor can drive the rotating shaft and the plurality of scrapers thereon to rotate, so that controlling the operation of the scrapers is more convenient and quick.

[0013] Preferably, the blade of the scraper faces away from the scraper assembly, that is, the scraper is located at the front side of the scraper assembly and its blade faces forward, so that during the operation of the pulling platform, the recycling bag can first pass through the blade and be cut.

[0014] In a specific implementation scheme, a detection module is provided in the running path of the pull-out platform on the front side of the scraper assembly or on the front end surface of the scraper assembly, and the detection module is used to detect recyclables or recycling bags; when the detection module detects recyclables or recycling bags, the multiple scrapers retreat into the through hole. In this scheme, based on the detection of the detection module, it can be judged that the recyclables or recycling bags are close to the scraper assembly. In order to avoid the scraper assembly from running in close contact with the pull-out platform, the scraper needs to be withdrawn. Therefore, this scheme controls the withdrawal action of the scraper based on the detection signal of the detection module.

[0015] In a further solution, the scraper assembly is laterally movable and arranged above the pull-out platform, and a plurality of detection sensors for detecting the height of recyclables inside the recycling bin directly below are arranged at the lower end of the pull-out platform; the plurality of detection sensors are arranged along the moving direction of the pull-out platform, and the scraper assembly laterally adjusts its position relative to the pull-out platform based on the height difference detected by the plurality of detection sensors. In this solution, since the pull-out platform moves relative to the scraper assembly, most of the recyclables will accumulate to the position of the scraper assembly before falling into the recycling bin, which will cause the recyclables in the recycling bin to accumulate unevenly, with the front side being lower and the rear side being significantly higher below the scraper assembly. In order to avoid the above situation affecting the storage capacity of the recycling bin, the scraper assembly is also arranged to be movable in this solution, so that the position of the scraper assembly can be adjusted forward, thereby adjusting the position where the recyclables fall into the recycling bin, so that the recyclables in the recycling bin can be stored more evenly.

[0016] In addition, when the height of recyclables detected by multiple detection sensors reaches the overflow value, an overflow alarm is triggered to remind the collection and transportation personnel to replace the recycling bin. This can avoid overflowing of the recycling bin and promptly remind people to replace the recycling bin to ensure the timely collection of recyclables.

[0017] Preferably, the bag collecting mechanism comprises a translation module, a lifting module arranged on the translation module, and a roller bag clamping module arranged on the lifting module; the roller bag clamping module comprises two groups of roller assemblies, and a bag clamping driving component driving the two groups of roller assemblies to move relatively closer or farther away; the roller assembly comprises a base, a roller rotatably arranged thereon, and a roller driving motor driving the roller to rotate; in the rotation direction of the rollers in the two groups of roller assemblies, soft rubber columns are arranged on the rolling surfaces of the rollers. The roller bag clamping module is used to clamp and release the recycling bag. When the bag clamping driving component drives the two groups of roller assemblies to move relatively closer, the two groups of rollers can roll against each other to roll part of the recycling bag between the two rollers, thereby clamping the recycling bag. When the bag clamping driving component drives the two groups of roller assemblies to move relatively farther away, the two groups of rollers can roll against each other to withdraw part of the recycling bag, thereby releasing the recycling bag.

[0018] Among them, the translation module is used to drive the bag collecting mechanism to move horizontally, so as to transfer the clamped recycling bag to the top of another empty bag recycling bucket.

[0019] The lifting module is used to control the roller bag clamping module to move up and down, and is used to clamp and lift the recycling bag.

[0020] In a specific embodiment, the bases of the two roller assemblies are both provided with a slide seat, the slide seats on the two roller assemblies are arranged opposite to each other, and the two opposite slide seats are provided with sliding assemblies connected to each other; when the bag clamping driving component drives the two roller assemblies to move closer or farther away from each other, the sliding assembly slides relative to the two slide seats. The bag clamping driving component is constructed as a bag clamping push rod motor, which is fixed to the base of one of the roller assemblies, and the output shaft is connected to the base of the other roller assembly.

[0021] Preferably, an AI camera component is provided on the internal frame of the box above the pull-out platform. The AI ​​camera component captures the processing results of recyclables, performs cloud-based AI analysis, and outputs and stores scoring data.

[0022] The steps of the cloud AI analysis specifically include:

[0023] Retrieve the recyclable sample images in the training set or the validation set, and use the feature extraction network to extract multi-scale features;

[0024] The extracted multi-scale features are sent to the RPN network to filter out the target area selection box of recyclables;

[0025] Based on the recyclable target area selection frame, retain high-quality and high-precision recyclable target candidate frames, and remove non-recyclable candidate frames;

[0026] Binding the recyclable object candidate frame features to the recyclable components, and evaluating the recyclable component segmentation results;

[0027] Scoring is based on the results of the recyclable material segmentation.

[0028] The first object of the present invention is to provide a recyclable resource utilization sorting method, which uses the recyclable resource utilization sorting line as described above and performs the following method:

[0029] S1: The conveyor belt delivers the bagged recyclables to the delivery port of the broken bag recycling box. The broken bag recycling box detects the recyclables and delivers them to the pull-out platform from the delivery port.

[0030] S2: The bag collecting mechanism moves down to the pull-out platform to roll up and clamp the recovery bag;

[0031] S3: The scraper of the bag-breaking blade assembly extends upward from the through hole above the drawer platform, and the bag-breaking blade assembly moves laterally with the drawer platform or the bag-collecting mechanism clamps the recovery bag and moves relative to the drawer platform, so that the scraper can break the recovery bag;

[0032] S4: When the detection module detects recyclables or recycling bags, the plurality of scrapers retreat into the through hole;

[0033] S5: The bag collecting mechanism moves upward to take away the recovered bag;

[0034] S6: The AI ​​camera component captures the processing results of the recyclables remaining after the bag is broken, performs cloud-based AI analysis, outputs the scoring data and stores it;

[0035] S7: The pull-out platform continues to move horizontally, and the scraper assembly is used to push the recyclables on the pull-out platform into the recycling bin;

[0036] Before the pulling platform moves sideways in step S1, multiple detection sensors at the lower end of the pulling platform detect the height of the recyclables inside the recycling bin below. When the multiple detection sensors detect that there is a height difference in the recyclables inside the recycling bin, the scraper assembly moves forward a certain distance in step S7 to adjust the position where the recyclables are hung.

[0048] Embodiment 1:

[0049] like Figures 1 to 6 As shown, this embodiment relates to a recyclable resource utilization sorting line, including a broken bag recovery box 10, and a conveyor belt 20 for conveying bagged recyclables to the delivery port of the broken bag recovery box 10; the broken bag recovery box 10 includes a bag receiving mechanism 3 and a bag breaking mechanism 2 installed on the internal frame 1 of the box body, and the bag receiving mechanism 3 moves and is arranged above the bag breaking mechanism 2 for rolling up the empty bag of recyclables and transferring it to the top of the empty bag recovery bin. The bag breaking mechanism 2 includes a pull-out platform 21 that is arranged below the delivery port for transverse movement, a scraper assembly 22 that is arranged above the pull-out platform 21, and a bag breaking blade assembly 23 that is arranged below the pull-out platform 21. The lower end surface of the scraper assembly 22 is fitted on the upper end surface of the pull-out platform 21, and the pull-out platform 21 is constructed with a through hole on the front side of the scraper assembly 22, and a scraper 231 is arranged on the bag breaking blade assembly 23. The scraper 231 can extend upward from the through hole to the pull-out platform 21. The present solution is different from the prior art in that the bag breaking mechanism 2 in the recyclable resource utilization sorting line adopts a pull-out platform 21 as a receiving platform below the delivery port, which is used to receive the recycling bag placed in the delivery port. In addition, a bag breaking blade assembly 23 is provided below the pull-out platform 21, and the scraper 231 of the bag breaking blade assembly 23 is movably arranged and can be extended or pushed into the through hole on the pull-out platform 21. In this way, when the scraper 231 extends upward from the through hole to the pull-out platform 21, the recycling bag can be cut at this time, so that the recyclables inside the recycling bag are scattered on the pull-out platform 21, and then the scraper 231 withdraws from the through hole. Finally, based on the relative movement of the pull-out platform 21 and the scraper assembly 22, the scraper assembly 22 pushes the recyclables on the pull-out platform 21 into the recycling bin. Based on the above scheme, the bag breaking mechanism 2 in the recyclable resource utilization sorting line has a streamlined structure, unchanged functions, less recyclable residues, more convenient cleaning, and lower costs.

[0050] In addition, the solution is equipped with an AI camera component 4 on the internal frame 1 of the box above the pull-out platform 21. The AI ​​camera component 4 captures the recyclable material processing results, performs cloud-based AI analysis, and outputs and stores the scoring data.

[0051] like Figures 2 to 4 As shown, the pulling platform 21 includes a disc body 211, and baffle walls 212 arranged on the left and right sides of the disc body 211. The middle part of the scraper assembly 22 is constructed as a protrusion that is compatible with the disc body 211 and the baffle walls 212 on both sides. In the scheme here, the baffle walls 212 on both sides can ensure that recyclables will not fall from both sides or get stuck in the moving track of the pulling platform 21. The bag breaking blade assembly 23 is fixedly connected to the bottom of the pulling platform 21, and the bag breaking blade assembly 23 moves laterally with the pulling platform 21. In this way, it can be ensured that the scraper 231 in the bag breaking blade assembly 23 is always aligned and synchronized with the through hole of the pulling platform 21. On the other hand, during the bag breaking process, the bag breaking blade assembly 23 can be used to move laterally synchronously with the pulling platform 21 to break the bag.

[0052] exist Figure 4 and 5 In the specific embodiment shown, the bag breaking blade assembly 23 includes a rotating shaft 232 positioned by a bearing group, a plurality of scrapers 231 arranged on the rotating shaft 232, and a scraper driving motor 233 driving the rotating shaft 232 and the plurality of scrapers 231 thereon to rotate. The scraper driving motor 233 drives the rotating shaft 232 and the plurality of scrapers 231 thereon to rotate in a path, and the plurality of scrapers 231 can extend out or retreat into the through hole. In the scheme here, the scraper driving motor 233 can drive the rotating shaft 232 and the plurality of scrapers 231 thereon to rotate, so that it is more convenient and quick to control the operation of the scraper 231. The blade of the scraper 231 faces away from the scraper assembly 22, that is, the scraper 231 is at the front side of the scraper assembly 22 and its blade faces forward, so that during the operation of the pulling platform 21, the recycling bag can first pass through the blade and be cut.

[0053] In a specific implementation scheme, a detection module is provided in the running path of the pull-out platform 21 on the front side of the scraper assembly 22 or on the front end surface of the scraper assembly 22, and the detection module is used to detect recyclables or recycling bags. When the detection module detects recyclables or recycling bags, the multiple scrapers 231 retreat into the through hole. In this scheme, based on the detection of the detection module, it can be judged that the recyclables or recycling bags are close to the scraper assembly 22. In order to avoid the scraper assembly 22 from running in close contact with the pull-out platform 21, the scraper 231 needs to be withdrawn. Therefore, this scheme controls the withdrawal action of the scraper 231 based on the detection signal of the detection module.

[0054] In a further solution, the scraper assembly 22 is arranged above the pull-out platform 21 in a lateral movement, and a plurality of detection sensors for detecting the height of recyclables inside the recycling bin directly below are arranged at the lower end of the pull-out platform 21. The plurality of detection sensors are arranged along the moving direction of the pull-out platform 21, and the scraper assembly 22 adjusts its position relative to the pull-out platform 21 laterally based on the height difference detected by the plurality of detection sensors. In this solution, since the pull-out platform 21 moves relative to the scraper assembly 22, most of the recyclables will accumulate to the position of the scraper assembly 22 before falling into the recycling bin, which will cause the recyclables in the recycling bin to accumulate unevenly, with the front side being lower and the rear side being significantly higher below the scraper assembly 22. In order to avoid the above situation affecting the storage capacity of the recycling bin, the scraper assembly 22 is also arranged to be movable in this solution, so that the position of the scraper assembly 22 can be adjusted forward, thereby adjusting the position where the recyclables fall into the recycling bin, so that the recyclables in the recycling bin can be stored more evenly. In addition, when the height of recyclables detected by multiple detection sensors reaches the overflow value, an overflow alarm is triggered to remind the collection and transportation personnel to replace the recycling bin. This can avoid overflowing of the recycling bin and promptly remind people to replace the recycling bin to ensure the timely collection of recyclables.

[0055] like Figure 2 , 3 and 6, the bag collecting mechanism 3 includes a translation module 31, a lifting module 32 arranged on the translation module 31, and a roller bag clamping module 33 arranged on the lifting module 32. The roller bag clamping module 33 includes two groups of roller assemblies, and a bag clamping driving component 331 that drives the two groups of roller assemblies to move relatively close or away. The roller assembly includes a base 332, a roller 333 rotatably arranged thereon, and a roller driving motor 334 that drives the roller 333 to rotate. The roller 333 in the two groups of roller assemblies rotates in a direction, and a soft rubber column is arranged on the rolling surface of the roller 333. The roller 333 bag clamping module 33 is used to clamp and release the recycling bag. When the bag clamping driving component 331 drives the two groups of roller assemblies to move relatively close, the two groups of rollers 333 can roll the recycling bag part between the two rollers 333 by rolling each other, so that the recycling bag can be clamped. When the bag clamping driving component 331 drives the two roller assemblies to move away from each other, the two rollers 333 rotate in opposite directions to roll each other to partially withdraw the recycling bag, thereby loosening the recycling bag. Among them, the translation module 31 is used to drive the bag collecting mechanism 3 to move horizontally, and is used to transfer the clamped recycling bag to the top of another empty bag recycling bucket. The lifting module 32 is used to control the roller 333 and the bag clamping module 33 to move up and down, and is used to clamp the recycling bag and lift the recycling bag.

[0056] In a specific embodiment, the bases 332 in the two roller assemblies are both provided with a chute seat 335, the chute seats 335 in the two roller assemblies are arranged opposite to each other, and the two opposite chute seats 335 are provided with a sliding assembly 336 connected to each other. When the bag clamping driving component 331 drives the two roller assemblies to move relatively closer or farther away, the sliding assembly 336 slides relative to the two chute seats 335. The bag clamping driving component 331 is constructed as a bag clamping push rod motor, which is fixed on the base 332 in one of the roller assemblies, and the output shaft is connected to the base 332 in the other roller assembly.

[0057] In another set of replaceable solutions, an output belt can be set under the bag breaking mechanism 2 of the bag breaking recovery box 10, that is, another set of conveyor belts can be set to receive the recyclables or recyclables for resource utilization after the bag is broken, and transport them to the next workstation, thereby realizing automated bag breaking assembly line operation.

[0058] Embodiment 2:

[0059] The first object of the present invention is to provide a recyclable resource utilization sorting method, using the recyclable resource utilization sorting line as described in Example 1, and performing the following method:

[0060] S1: The conveyor belt 20 delivers the bagged recyclables to the delivery port of the broken bag recycling box 10 , and the broken bag recycling box 10 detects that the recyclables are dropped from the delivery port onto the pulling platform 21 .

[0061] S2: The bag collecting mechanism 3 moves downward to the drawing platform 21 to roll up and clamp the recovery bag.

[0062] S3: The scraper 231 of the bag breaking blade assembly 23 extends upward from the through hole above the pulling platform 21, and the bag breaking blade assembly 23 moves laterally with the pulling platform 21 or the bag collecting mechanism 3 clamps the recovery bag and moves relative to the pulling platform 21, so that the scraper 231 can break the recovery bag.

[0063] S4: When the detection module detects recyclables or recycling bags, the multiple scrapers 231 retreat into the through holes.

[0064] S5: The bag collecting mechanism 3 moves upward to clamp and take away the recovered bag.

[0065] S6: The AI ​​camera component 4 captures the processing results of the recyclables remaining after the bag is broken, performs cloud AI analysis, outputs the scoring data and stores it. The steps of the cloud AI analysis specifically include:

[0066] S 6.1, retrieve the recyclable sample images in the training set or the validation set, and use the feature extraction network to extract multi-scale features.

[0067] S 6.2, the extracted multi-scale features are sent to the RPN network to filter out the recyclable target area selection box.

[0068] S 6.3, based on the recyclable target area selection frame, retain high-quality and high-precision recyclable target candidate frames, and remove non-recyclable candidate frames. Bind the recyclable target candidate frame features to the recyclable components, and evaluate the recyclable component segmentation results.

[0069] S 6.4, scoring based on the results of the recyclable material segmentation.

[0070] S7: The pulling platform 21 continues to move laterally, and the scraper assembly 22 is used to push the recyclables on the pulling platform 21 into the recycling bin.

[0071] Before the pulling platform 21 moves horizontally in step S1, multiple detection sensors at the lower end of the pulling platform 21 detect the height of the recyclables inside the recycling bin below. When the multiple detection sensors detect that there is a height difference in the recyclables inside the recycling bin, the scraper assembly 22 moves forward a certain distance in step S7 to adjust the position where the recyclables are hung.
