[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] Figure 1 A flowchart of a plastic bottle sorting method provided in an embodiment of the present invention is provided. This embodiment is applicable to the scenario of sorting multiple recycled plastics. The method can be performed by a plastic bottle sorting device provided in an embodiment of the present invention, and the device can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device, such as a computer, a server, etc. The following embodiments will be described by taking the device integrated into an electronic device as an example. Reference Figure 1 , the method may specifically include the following steps:

[0026] Step 101, sorting the size of multiple plastic bottles by a drum screen to obtain multiple large bottles and multiple small bottles. This step sorts the plastic bottles based on the size, which can facilitate the subsequent sorting of the size-sorted plastic bottles based on use and material, facilitate subsequent processing and facilitate the rational use of recycled plastic bottles.

[0027] It is understandable that plastic bottles are generally granulated after recycling, and the temperature, time and other conditions required for melt granulation of plastic bottles of different sizes may be different. Plastic bottles of uniform size are easier to control process parameters during granulation, making the quality of plastic particles more stable and the particle size distribution more uniform. In addition, the recycled plastics can be used to produce various plastic products, and different products have different requirements for the performance and specifications of plastics. For example, the production of large plastic containers may require larger plastic sheets or particles, while the production of small plastic products requires smaller raw materials. Through size sorting, plastic bottles can be classified and processed into raw materials of different specifications to meet the production needs of diversified products. In addition, in general, large plastic bottles may have thicker walls and relatively better material strength and toughness; small plastic bottles may pay more attention to lightness and flexibility. After sorting by size, they can be allocated to more suitable application areas according to the material characteristics of different plastic bottles to maximize the utilization of resources.

[0028] Optionally, the plurality of large bottles include large bottles used as oil bottles and large bottles for other purposes, such as mineral water bottles and the like.

[0029] Optionally, the plurality of vials include a plurality of PET (polyethylene terephthalate) material vials and a plurality of HDPE (high-density polyethylene) material vials.

[0030] Optionally, the plurality of vials include a plurality of PP (polypropylene) material vials and a plurality of miscellaneous material vials.

[0031] Specifically, the above-mentioned small bottles made of miscellaneous materials can be understood as plastic small bottles made of other materials except PET material, HDPE material and PP material.

[0032] Specifically, the drum screen may include a single-stage drum screen or a multi-stage drum screen.

[0033] Optionally, the process of sorting the plurality of plastic bottles by size using a drum screen to obtain a plurality of large bottles and a plurality of small bottles includes:

[0034] After the above-mentioned multiple plastic bottles are sent into the drum screen, the plastic bottles in the drum screen are broken up, and the plastic bottles with a size smaller than the screen aperture of the drum screen fall into the collecting device below the drum screen to obtain the above-mentioned multiple small bottles, and the large bottles with a size larger than the screen aperture of the drum screen are discharged from the tail end of the drum screen to obtain the above-mentioned multiple large bottles.

[0035] Step 102, based on the purpose of each large bottle, the artificial intelligence robot is used to sort the plurality of large bottles to obtain a large bottle sorting result. This step can automatically, accurately and efficiently sort the large bottles by using the artificial intelligence robot.

[0036] It is understandable that plastics with different uses use different processing techniques in the production process, and recycling also requires targeted processes. In addition, in some specific industries, such as medical and electronics, there are strict industry specifications and standards for the quality and performance of plastic products. Therefore, sorting multiple large bottles based on the purpose of each large bottle can help improve processing efficiency and reduce costs in subsequent recycling. It can also help ensure that the recycled plastic bottles meet the requirements of the corresponding industry and help establish a standardized and orderly plastic recycling market.

[0037] Optionally, based on the purpose of each large bottle, an artificial intelligence robot is used to sort multiple large bottles to obtain large bottle sorting results, including:

[0038] Based on whether each large bottle is used as an oil jug, an artificial intelligence robot is used to sort out large bottles used as oil jugs and large bottles for other purposes from each large bottle, and correspondingly obtain an oil jug sorting group and a non-oil jug sorting group as the large bottle sorting results.

[0039] Understandably, large plastic bottles used as oil cans are difficult to clean because of the large amount of grease left inside. If they are mixed with other large plastic bottles, they may not be cleaned thoroughly, and the residual oil may affect the subsequent recycling process. For example, during the plastic melting stage, the oil may produce odor, affect the melting quality of the plastic, and even cause equipment failure. By sorting out the oil cans separately, special cleaning processes and equipment can be used to remove the oil in a targeted manner, improving the cleaning effect and recycling quality.

[0040] Optionally, the above-mentioned artificial intelligence robot is composed of a recognition module and a four-axis robotic arm. The recognition module relies on image recognition technology or near-infrared recognition technology. After identifying large bottles used as oil pots and large bottles for other purposes, 2 or more groups of robotic arms perform material sorting work, and sort the above-mentioned oil pot sorting group and non-oil pot sorting group properly, and send the large bottles used as oil pots and large bottles for other purposes to the oil pot collection bin and other purpose large bottle collection bin through the pneumatic conveying system.

[0041] Optionally, the process of sorting a plurality of large bottles by an artificial intelligence robot based on the purpose of each large bottle to obtain a large bottle sorting result includes:

[0042] Based on the purpose of each large bottle, an artificial intelligence robot is used to sort out large bottles used as oil bottles, large bottles made of non-oil bottles PET materials, and large bottles made of non-oil bottles HDPE materials from each large bottle, thereby obtaining oil bottle large bottle sorting group, non-oil bottle PET large bottle sorting group, and non-oil bottle HDPE large bottle sorting group.

[0043] Specifically, the plurality of large bottles may be sorted according to whether the large bottles are used for food packaging, medical supplies packaging, electronic product packaging, etc.

[0044] Step 103, grouping each vial based on the corresponding material through an eddy current sorter and a visible light sorter to obtain multiple material category vial groups, and determining the vial sorting results based on the multiple material category vial groups. This step can efficiently and accurately sort the plastic vials by using an eddy current sorter and a visible light sorter, and combined with steps 101 and 102, it can reduce the sorting cost, improve the sorting efficiency, avoid secondary pollution and avoid subjective judgment errors without relying on manual sorting, and comprehensively sort the plastic bottles from the dimensions of size, use and material, which can improve the accuracy of sorting, thereby avoiding affecting the subsequent processing industry and ensuring the quality stability of the industrial chain.

[0045] Specifically, the above-mentioned visible light sorting machine can be an artificial intelligence visible light sorting machine that integrates artificial intelligence technology and visible light detection technology.

[0046] Optionally, the above-mentioned visible light sorting machine includes a conveying unit, a recognition unit and an execution unit.

[0047] Specifically, the above-mentioned recognition unit can be constructed based on image recognition algorithm and / or near infrared recognition technology.

[0048] Optionally, the process of grouping the vials based on the corresponding materials by using an eddy current separator and a visible light separator to obtain multiple material category vial groups includes:

[0049] The PET vials, HDPE vials and PP vials in each vial are sorted out by a visible light sorter, and then the remaining vials are sent to an eddy current sorter to sort out the metal vials mixed in multiple vials.

[0050] The following is a further introduction to the plastic bottle sorting method provided by an embodiment of the present invention.

[0051] Optionally, the drum screen includes a first-stage drum screen and a second-stage drum screen.

[0052] Specifically, the drum diameter, screen mesh aperture, and length of the first-stage drum screen and the second-stage drum screen can be set based on experience.

[0053] Optionally, the drum diameter of the first-stage drum screen and the second-stage drum screen can be set to 1.8m-3m, the screen apertures of the first-stage drum screen and the second-stage drum screen can be set to 20mm-60mm and 200mm-600mm respectively, and the lengths of the first-stage drum screen and the second-stage drum screen can be set to 1m-5m and 2m-8m respectively.

[0054] Optionally, a material lifting device is installed in the first-stage drum screen and the second-stage drum screen to break up the plastic bottle materials in the drum.

[0055] Optionally, the lifting device and the screen of the drum screen are both detachable to facilitate cleaning, maintenance and replacement.

[0056] Optional, such as Figure 2 As shown, Figure 1 Step 101 in the method may include the following steps:

[0057] Step 1011, slag mixed in the plurality of plastic bottles is screened out by a first-stage drum screen.

[0058] Specifically, a slag collection box may be provided below the first-stage drum screen to collect the fallen slag.

[0059] Specifically, after passing through the first-stage drum screen, a plurality of plastic bottles enter the second-stage drum screen.

[0060] Step 1012, selecting a plurality of small bottles from a plurality of plastic bottles through second-stage drum screening.

[0061] Specifically, a collecting device and a conveying belt may be provided below the second-stage drum screen to collect the fallen vials and convey them to subsequent processing links.

[0062] Step 1013, obtaining the plastic bottles remaining after sorting out a plurality of small bottles from a plurality of plastic bottles, to obtain a plurality of large bottles.

[0063] Specifically, the embodiment of the present invention can screen out slag in multiple small bottles and sort out large bottles and small bottles from multiple small bottles by utilizing a two-stage drum screen, which can help improve the accuracy of subsequent pricing and avoid the impact of mixed slag and mixed sizes on subsequent processing.

[0064] The following is a further introduction to the plastic bottle sorting method provided by an embodiment of the present invention.

[0065] Optionally, the aforementioned visible light sorting machine includes a first visible light sorting machine and a second visible light sorting machine.

[0066] Optional, such as Figure 3 As shown, Figure 1 Step 103 in the method may include the following steps:

[0067] Step 103A1, sorting out metal vials mixed in multiple vials by using an eddy current sorter, and obtaining vials remaining after the metal vials are sorted out from the multiple vials, to obtain multiple first sorted remaining vials.

[0068] Optionally, the eddy current separator is a combined eddy current separator, and the process of separating out metal vials mixed in a plurality of vials by the eddy current separator includes: separating out iron cans and aluminum cans from the plurality of vials respectively by the combined eddy current separator.

[0069] Step 103A2, sorting out a plurality of PET material vials from a plurality of first sorting remaining vials by a first visible light sorting machine to obtain a PET material vial group, and obtaining the remaining vials after sorting out a plurality of PET material vials from a plurality of first sorting remaining vials to obtain a plurality of second sorting remaining vials.

[0070] Step 103A3, using a second visible light sorter to sort out a plurality of HDPE vials from the plurality of second sorting remaining vials to obtain a HDPE vial group.

[0071] Step 103A4, obtaining the remaining vials after sorting out the multiple HDPE material vials from the multiple second sorting remaining vials to obtain multiple third sorting remaining vials.

[0072] Step 103A5, sorting out a plurality of PP material vials and a plurality of miscellaneous material vials from the plurality of third sorting remaining vials by an artificial intelligence robot, and obtaining a PP material vial group and a miscellaneous material vial group accordingly.

[0073] Optionally, the process of sorting a plurality of PP material vials and a plurality of miscellaneous material vials from a plurality of third sorting remaining vials by an artificial intelligence robot to obtain a PP material vial group and a miscellaneous material vial group includes:

[0074] The recognition module of the artificial intelligence robot identifies the PP material vials and the miscellaneous material vials, and the artificial intelligence robot's mechanical arm performs material sorting to obtain the above-mentioned PP material vial group and miscellaneous material vial group.

[0075] Optionally, the vial sorting results corresponding to the HDPE vial group include: a first HDPE vial sorting group, a second HDPE vial sorting group, and a third HDPE vial sorting group. The process of determining the vial sorting results based on multiple material category vial groups includes:

[0076] The large white HDPE vials, small white HDPE vials and flower HDPE vials in the HDPE material vial group are sorted out by a multi-channel sorting machine, and the first HDPE vial sorting group, the second HDPE vial sorting group and the third HDPE vial sorting group are obtained accordingly.

[0077] Specifically, the HDPE material bottle group can be sent to a multi-channel sorting machine, and the multi-channel sorting machine can be used to sort out the large white HDPE bottles, small white HDPE bottles and flower HDPE bottles in the HDPE material bottle group, and the first HDPE bottle sorting group, the second HDPE bottle sorting group and the third HDPE bottle sorting group can be obtained accordingly. After that, the large white HDPE bottles, small white HDPE bottles and flower HDPE bottles can be sent to the large white material collection bin, the small white material collection bin and the flower HDPE collection bin respectively through the pneumatic conveying system.

[0078] It is understandable that due to the different recycling values, processing performances and impurity contents of large white material, small white material and flowered plastic material, large white material, small white material and flowered plastic material can help improve the convenience of subsequent processing, and further facilitate the subsequent efficient and accurate pricing of recycled plastic bottles.

[0079] Optionally, the vial sorting results include: a metal vial sorting group, a PP vial sorting group, and a miscellaneous material vial sorting group. The aforementioned process of determining the vial sorting results based on multiple material category vial groups includes:

[0080] The metal vials, PP vial groups and miscellaneous material vial groups are obtained, and the metal vial sorting group, PP vial sorting group and miscellaneous material vial sorting group are obtained accordingly.

[0081] Optionally, the aforementioned process of determining vial sorting results based on multiple material category vial groups includes: respectively obtaining iron cans and aluminum cans in the metal vials, and obtaining an iron can sorting group and an aluminum can sorting group accordingly.

[0082] Specifically, the iron can sorting group, the aluminum can sorting group, the PP small bottle sorting group and the sundry material small bottle sorting group can be sent to the iron can collecting bin, the aluminum can collecting bin, the PP small bottle collecting bin and the sundry material small bottle collecting bin respectively.

[0083] The embodiment of the present invention first uses an eddy current sorter to sort out mixed metal vials from multiple vials, then uses a visible light sorter to successively sort out PET vials and HDPE vials from the multiple vials, and finally uses an artificial intelligence robot to sort out PP material and miscellaneous material vials, which can maximize the sorting speed of vials of different materials and improve the sorting accuracy.

[0084] It is understandable that firstly, the eddy current sorting machine can quickly sort out the mixed metal vials based on the characteristics of the metal vials, and can avoid the repeated identification operation of the metal vials by the visible light sorting machine and the artificial intelligence robot; in addition, the most common plastic bottle materials in recycled plastic bottles are PET and HDPE. The visible light sorting machine with low cost, high speed, high stability and sensitivity to specific characteristics can quickly and accurately complete the sorting of most small plastic bottles, and then use the artificial intelligence robot with high cost but high accuracy and flexibility to accurately sort the remaining small number of small plastic bottles, so that the sorting of all small plastic bottles can be completed efficiently and accurately as a whole.

[0085] It is understandable that when the plurality of vials do not include PP material vials and mixed material vials, steps 103A4 and 103A5 do not need to be performed.

[0086] The following is a further introduction to the plastic bottle sorting method provided by an embodiment of the present invention.

[0087] Optionally, the vial sorting results corresponding to the PET material vial group include: a first PET vial sorting group, a second PET vial sorting group, a third PET vial sorting group, a fourth PET vial sorting group, a fifth PET vial sorting group and a sixth PET vial sorting group.

[0088] Optional, such as Figure 4 As shown, Figure 1 Step 103 in may include the following steps.

[0089] Step 103B1, sorting out the label paper on the PET vials in the PET material vial group by using a label stripping machine and a negative pressure air separator to obtain a first PET vial sorting group.

[0090] Specifically, the plurality of PET vials sorted by the first visible light sorting machine can be fed to the label removal machine by the screw conveyor, and then transported to the negative pressure sorting machine for label removal. The heavier bottles fall on the conveyor belt due to gravity and are transported to the subsequent processing link, and the lighter label paper is collected by the negative pressure to obtain the first PET vial sorting group. Specifically, the label paper can be collected in the PET vial label paper collection bin.

[0091] Step 103B2, obtaining the PET vials from the PET material vial group after sorting out the trademark paper to obtain the label-free PET vials, and sorting out the bottle caps of the label-free PET vials through a bulk feeder to obtain a second PET vial sorting group.

[0092] Specifically, the PET bottles after being stripped of labels can be fed into a bulk feeder through a conveyor belt. The bulk feeder can be composed of multiple sets of sieve plates. The gap between the sieve plates can be set based on the size of the bottle caps, for example, it can be set to 35 mm. The main function of the bulk feeder is to break up the bottle bodies and knock off the bottle caps. The bottle caps can be collected under the bulk feeder screen to obtain a second PET vial sorting group. Specifically, the bottle caps can be collected in a PET vial cap collection bin.

[0093] Step 103B3, obtaining the PET vials of the PET material vial group after the bottle caps are sorted out to obtain PET vial bodies, and sorting out the transparent PET bottle bodies in the PET vial bodies through a third visible light sorting machine to obtain a third PET vial sorting group.

[0094] Specifically, all PET vials can be sent to the third visible light sorting machine, and the transparent bottles in all PET vials can be sorted out by the third visible light sorting machine to obtain a third PET vial sorting group, and then the transparent bottles in the PET vials can be collected into the transparent PET vial collection bin.

[0095] Step 103B4, obtain the remaining PET bottles in the PET material vial group after the transparent PET bottles are sorted out to obtain non-transparent PET bottles, and use the fourth visible light sorting machine to sort out the blue PET bottles and the green PET bottles in the non-transparent PET bottles to obtain the fourth PET vial sorting group and the fifth PET vial sorting group accordingly.

[0096] Optionally, the fourth visible light sorting machine adopts a dual-channel design, including a left channel and a right channel.

[0097] Specifically, all non-transparent PET bottles can be sent to the right channel of the fourth visible light sorting machine, and blue PET bottles can be sorted out through the right channel to obtain the fourth PET vial sorting group; then the remaining non-transparent bottles can be sent to the left channel of the fourth visible light sorting machine, and green PET bottles can be sorted out through the left channel to obtain the fifth PET vial sorting group. Then the blue bottles and green bottles in the PET vials can be collected into the blue PET vial collection bin and the green PET vial collection bin respectively.

[0098] Step 103B5, obtaining the remaining vials in the PET material vial group after the transparent PET bottle body, the blue PET bottle body and the green PET bottle body are sorted out, and obtaining a sixth PET vial sorting group.

[0099] Specifically, the remaining PET vials except the transparent PET bottle bodies, the blue PET bottle bodies and the green PET bottle bodies can be collected into the miscellaneous PET vial collection bin.

[0100] It is understandable that PET bottles, bottle caps and label papers are generally made of different materials. Plastics of different materials have different melting temperatures and physical properties during the recycling and reprocessing process. If they are not separated, the purity of the recycled PET material will be reduced, affecting the quality and performance of the recycled PET, making it difficult to use in high-end applications. Therefore, sorting the bottle body, bottle cap and label paper of the PET bottle can help improve the convenience of subsequent processing and utilization and improve the quality and performance of the recycled products. The reason why HDPE does not need to be sorted is that the bottle cap of the HDPE plastic bottle is generally made of the same HDPE material as the bottle body. During the recycling and reprocessing process, the melting temperature and physical properties of the two are relatively matched. Mixed recycling will not have much impact on the performance of HDPE. They can be recycled and reused together, and the quality of the recycled materials will not be significantly reduced. Impurities such as label paper and adhesives have relatively little effect on it. Even if there is a small amount of label paper remaining, it is relatively easy to remove in the cleaning process, and generally will not cause serious quality problems in subsequent processing; in addition, HDPE plastic bottles have a wide range of uses, and the requirements for material purity are not as high as PET plastic bottles. Recycled HDPE plastic bottles can be used to produce some products that do not require high purity, such as plastic pipes, plastic barrels, garbage bags, etc. Even if there are some other impurities on the bottle cap or it is slightly different from the material of the bottle body, it will not affect its application in these fields.

[0101] It is understandable that different masterbatches, additives, etc. may be added to PET bottles of different colors during the production process. For example, some dark-colored plastic bottles may use masterbatches containing heavy metals and other harmful substances. If they are mixed with light-colored or colorless plastic bottles for recycling, heavy metals and other impurities may migrate to the originally pure PET material, affecting the sanitary quality of the recycled PET, making it unable to meet the requirements of food packaging and other fields with high sanitation requirements. Therefore, sorting PET bottles of different colors can avoid cross contamination; and the adsorption and cleaning difficulty of stains on the surface of PET plastic bottles of different colors may be different. Generally speaking, stains on the surface of dark-colored plastic bottles may be more difficult to detect and are easily overlooked during the cleaning process, resulting in incomplete cleaning. However, stains on the surface of light-colored or colorless plastic bottles are easier to observe, and can be treated more specifically during cleaning, improving the overall cleaning effect and ensuring that the recycled PET plastic bottles meet the sanitation standards; in addition, colorless or light-colored PET plastic bottles are more likely to meet the sanitation standards for food packaging after recycling. Food packaging has very strict sanitation requirements for plastic materials, and it is necessary to ensure that the plastic does not contain harmful substances, no odor, no pigment migration, etc. Separating colorless or light-colored PET plastic bottles for recycling can better control the quality of recycled PET, make it meet the standards of food contact grade plastics, and achieve efficient use of resources.

[0102] An embodiment of the present invention also provides a plastic bottle sorting method. This embodiment can be applied to scenarios where prices of multiple recycled plastics are calculated. The method can specifically include the following steps: based on the large bottle sorting results and small bottle sorting results provided by any embodiment of the present invention, calculate the total price of multiple plastic bottles.

[0103] Optionally, the process of calculating the total price of multiple plastic bottles based on the large bottle sorting result and the small bottle sorting result provided in any embodiment of the present invention includes:

[0104] Based on the large bottle sorting results of two large bottle sorting groups including the oil bottle sorting group and the non-oil bottle sorting group, and the small bottle sorting results of 13 small bottle sorting groups including the first HDPE small bottle sorting group, the second HDPE small bottle sorting group, the third HDPE small bottle sorting group, the iron can sorting group, the aluminum can sorting group, the PP small bottle sorting group, the miscellaneous material small bottle sorting group, the first PET small bottle sorting group, the second PET small bottle sorting group, the third PET small bottle sorting group, the fourth PET small bottle sorting group, the fifth PET small bottle sorting group and the sixth PET small bottle sorting group, the total price of the above-mentioned multiple plastic bottles is calculated.

[0105] Specifically, a weighing device can be set for the collecting bin corresponding to each sorting group to weigh the sorting groups sent to each collecting bin to obtain the weight of each sorting group, and then the total price of multiple plastic bottles is calculated based on the weight of each sorting group and the plastic bottle recycling price corresponding to the plastic bottles of each sorting group.

[0106] Optionally, when the weighing readings of the collecting bins corresponding to the first HDPE vial sorting group, the second HDPE vial sorting group, the third HDPE vial sorting group, the PP vial sorting group, the miscellaneous material vial sorting group, the third PET vial sorting group, the fourth PET vial sorting group, the fifth PET vial sorting group and the sixth PET vial sorting group reach the full bin prompt range, the corresponding collecting bin automatically opens the horizontal fully automatic baler to feed the materials, and after the horizontal fully automatic baler compresses the corresponding plastic bottles into bottle bricks, the compressed bottle bricks are transported to the designated corresponding temporary storage area by a fully automatic forklift (Automated Guided Vehicle, AGV).

[0107] Optionally, after weighing is completed in the collection bins corresponding to the iron can sorting group and the aluminum can sorting group, the iron cans and aluminum cans are transferred to a metal compression baler to be compressed into blocks by a fully automatic forklift, and then the compressed iron cans and aluminum cans are transported to the designated corresponding temporary storage area by a fully automatic forklift.

[0108] Optionally, after the collecting bin corresponding to the first PET vial sorting group is weighed, the trademark paper of the first PET vial sorting group is transferred to the trademark paper compressor for compression into blocks by a fully automatic forklift, and then the compressed trademark paper blocks are transported to the designated corresponding temporary storage area by a fully automatic forklift.
