Description

Technical Field

[0001] This invention relates to the field of recyclable waste sorting technology, and in particular, to an intelligent recycling sorting system and method for recyclable materials after waste sorting. Background Technology

[0002] Waste sorting refers to the classification and storage of waste according to regulations. It is generally divided into kitchen waste, hazardous waste, other waste, and recyclable waste. Recyclable waste, through sorting and recycling, can be transformed from waste into valuable resources. However, current recyclable waste sorting systems typically employ unidirectional sorting production lines that include photoelectric and artificial intelligence sorting systems. This unidirectional process results in long production lines that require significant installation space. Furthermore, to improve the sorting efficiency of unidirectional sorting lines, a large number of sorting devices are needed, leading to high investment costs. It also makes it difficult to achieve precise sorting and recycling. For example, patent CN111715674A discloses an intelligent sorting process and system for high-value recyclable materials in waste sorting. The intelligent sorting system includes a flower disc screen, a three-phase diversion screen, a photoelectric sorting device, and an artificial intelligence sorting machine connected in sequence. Mixed waste passes through these four sorting devices sequentially to be sorted into different types of recyclable waste. The entire sorting production line is long, and to ensure sorting efficiency, a large number of each type of sorting device are required, resulting in high investment costs. Moreover, the number of recyclable waste types sorted is relatively small. In addition, the sorting device has a low effective utilization rate. For example, when there is no cardboard or plastic film in the mixed waste, the flower disc screen is ineffective. Summary of the Invention

[0003] This invention provides an intelligent recycling sorting system and method for recyclable materials after waste sorting, in order to solve the technical problems of existing recyclable waste sorting systems, such as large installation space, high investment costs, and difficulty in achieving precise sorting and recycling.

[0004] According to one aspect of the present invention, an intelligent recycling sorting system for recyclable materials after waste sorting is provided, comprising a first conveying mechanism, an intelligent sorting device, a second conveying mechanism, and a sorting and storage device. The first conveying mechanism is used to input mixed recyclable materials, and the intelligent sorting device is used to sort and recycle the mixed recyclable materials input by the first conveying mechanism to sort different types of recyclable materials into different sorting and storage devices. After each sorting, the remaining recyclable materials are conveyed to the second conveying mechanism. The second conveying mechanism is used to cyclically convey recyclable materials to the first conveying mechanism, and after all recyclable materials have been sorted, the remaining materials are conveyed downstream.

[0005] Furthermore, the intelligent sorting device operates in different modes depending on the number of times the recyclables are transported, so as to sort various types of recyclables into corresponding classification and storage devices during multiple transport cycles.

[0006] Furthermore, the intelligent sorting device includes a light sorter, which corresponds to multiple sorting and storage devices. During each cycle of transporting recyclable materials, the light sorter sorts one type of recyclable material into the corresponding sorting and storage device. The number of sorted recyclable material types is equal to the number of cycles and the number of sorting and storage devices.

[0007] Furthermore, the intelligent sorting device includes at least two optical sorters. Adjacent optical sorters are connected by a third conveying mechanism for transporting recyclables. Each optical sorter corresponds to the same number of sorting and storage devices. Different optical sorters sort out different types of recyclables in each sorting operation, so as to complete the sorting of at least two types of recyclables in one cycle of conveying. The number of types of recyclables sorted out is equal to the product of the number of cycles of conveying and the number of optical sorters.

[0008] Furthermore, the intelligent sorting device includes at least one intelligent robot, each intelligent robot corresponding to multiple classification and storage devices. During each cycle of transporting recyclables, each intelligent robot sorts multiple types of recyclables into different classification and storage devices. The number of types of recyclables sorted out is equal to the product of the number of cycles and the number of types of recyclables sorted by the intelligent robot each time.

[0009] Furthermore, an automated storage bin is provided between the intelligent sorting device and the second conveying mechanism to temporarily store the remaining materials after sorting during each sorting operation.

[0010] In addition, the present invention also provides an intelligent recycling sorting method for recyclable materials after waste sorting, which adopts the intelligent recycling sorting system described above and includes the following:

[0011] The mixed recyclable material is fed into the first conveying mechanism;

[0012] The intelligent sorting device is controlled to sort and recycle the input mixed recyclables, so as to sort different types of recyclables into different classification storage devices, and after each sorting, the remaining recyclables are transported to the second conveying mechanism.

[0013] The second conveying mechanism is controlled to circulate and transport recyclable materials to the first conveying mechanism;

[0014] Repeat the above process until all types of recyclables have been sorted, then control the second conveyor to transport the remaining material downstream.

[0015] Furthermore, the intelligent sorting device includes a light sorter, which corresponds to multiple sorting and storage devices. During each cycle of transporting recyclable materials, the light sorter sorts one type of recyclable material into the corresponding sorting and storage device. The number of sorted recyclable material types is equal to the number of cycles and the number of sorting and storage devices.

[0016] Furthermore, the intelligent sorting device includes at least two optical sorters. Adjacent optical sorters are connected by a third conveying mechanism for transporting recyclables. Each optical sorter corresponds to the same number of sorting and storage devices. Different optical sorters sort out different types of recyclables in each sorting operation, so as to complete the sorting of at least two types of recyclables in one cycle of conveying. The number of types of recyclables sorted out is equal to the product of the number of cycles of conveying and the number of optical sorters.

[0017] Furthermore, the intelligent sorting device includes at least one intelligent robot, each intelligent robot corresponding to multiple classification and storage devices. During each cycle of transporting recyclables, each intelligent robot sorts multiple types of recyclables into different classification and storage devices. The number of types of recyclables sorted out is equal to the product of the number of cycles and the number of types of recyclables sorted by the intelligent robot each time.

[0018] The present invention has the following effects:

[0019] The intelligent recycling sorting system for recyclable materials after waste sorting of this invention uses a second conveying mechanism to circulate recyclable materials. The intelligent sorting device can sort out at least one type of recyclable material during each cycle. The system controls the intelligent sorting device to execute different working modes at different cycles, meaning that different types of recyclable materials are sorted out each time. Thus, all types of recyclable materials can be sorted out through multiple cycles. By adopting a circular transportation method for recyclable materials and controlling the intelligent sorting device to execute different working modes during each cycle, the sorting of all types of recyclable materials can be completed through multiple cycles. The cyclical sorting process significantly shortens the length of the sorting production line, thereby greatly reducing the space occupied. Furthermore, only one type of sorting equipment needs to be invested in, greatly reducing investment costs and significantly improving the effective utilization efficiency of the sorting equipment. At the same time, the number and types of recyclable materials sorted out are positively correlated with the number of cycles; the more cycles, the more types of recyclable materials are sorted out, achieving refined sorting and recycling.

[0020] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] like Figure 1As shown, a preferred embodiment of the present invention provides an intelligent recycling sorting system for recyclable materials after waste sorting, including a first conveying mechanism, an intelligent sorting device, a second conveying mechanism, and a sorting and storage device. The first conveying mechanism is used to input mixed recyclable materials, and the intelligent sorting device is used to sort and recycle the mixed recyclable materials input by the first conveying mechanism, so as to sort different types of recyclable materials into different sorting and storage devices. After each sorting, the remaining recyclable materials are conveyed to the second conveying mechanism. The second conveying mechanism is used to cyclically convey recyclable materials to the first conveying mechanism, and after all recyclable materials have been sorted, the remaining materials are conveyed downstream. It is understood that the intelligent sorting device is an existing product, and its specific structure will not be described in detail here. As an example, the intelligent sorting device of the present invention includes a material input mechanism, an intelligent sorting machine, and a material output mechanism. The first conveying mechanism conveys the mixed recyclable materials to the material input mechanism, and then the material input mechanism conveys them to the intelligent sorting machine. After each sorting is completed, the material output mechanism conveys the remaining materials to the second conveying mechanism. The first and second conveying mechanisms can be one or two of chain conveyors, belt conveyors, and roller conveyors. For example, both the first and second conveying mechanisms can be chain conveyors or belt conveyors, or the first conveying mechanism can be a chain conveyor and the second conveying mechanism can be a belt conveyor. Of course, in other embodiments of the invention, the first and second conveying mechanisms can also be other types of conveying mechanisms. Preferably, both the first and second conveying mechanisms are belt conveyors. When the second conveying mechanism rotates forward, it circulates recyclable materials to the first conveying mechanism, and when the second conveying mechanism rotates in reverse, it transports the remaining materials after sorting to the downstream process. Furthermore, the sorting and storage device is exemplarily described using a recycling bin, but any other container or transfer equipment can be used instead, without specific limitations.

[0028] It is understood that after the upstream process inputs material into the first conveying mechanism, the first conveying mechanism transports the mixed recyclables to the intelligent sorting device. The intelligent sorting device sorts at least one type of recyclable from the mixed recyclables into a classified storage device for storage. The mixed recyclable waste includes at least two types of recyclable waste, which can be mixed construction waste, mixed renovation waste, or any other loose mixed waste. Then, the intelligent sorting device transports the remaining recyclables after sorting to the second conveying mechanism, which then circulates the remaining recyclables back to the first conveying mechanism. This continuous circulation of recyclables continues until all types of recyclables are sorted and stored separately. Finally, the second conveying mechanism transports the remaining material to the downstream process. It is understood that the remaining material transported to the downstream process by the second conveying mechanism refers to recyclables that cannot be identified through the cyclical sorting and / or other types of waste mixed in during material input.

[0029] It is understood that the intelligent circular sorting system for recyclable materials after waste sorting in this embodiment uses a second conveying mechanism to circulate the recyclable materials. The intelligent sorting device can sort out at least one type of recyclable material during each circular conveying process. The system controls the intelligent sorting device to execute different working modes at different numbers of circular conveying cycles, meaning that different types of recyclable materials are sorted out each time. Thus, all types of recyclable materials can be sorted out through multiple circular conveying processes. This intelligent circular sorting system of the present invention, by adopting a circular conveying method for recyclable materials and controlling the intelligent sorting device to execute different working modes during each circular conveying cycle, can complete the sorting of all types of recyclable materials through multiple cycles. The cyclical sorting process greatly shortens the length of the sorting production line, thereby significantly reducing the space occupied. Furthermore, only one type of sorting equipment needs to be invested in, greatly reducing investment costs and significantly improving the effective utilization efficiency of the sorting equipment. At the same time, the number of types of recyclable materials sorted out is positively correlated with the number of circular conveying cycles; the more circular conveying cycles, the more types of recyclable materials are sorted out, achieving refined sorting and recycling.

[0030] Preferably, an automated storage bin is also provided between the intelligent sorting device and the second conveying mechanism to temporarily store the remaining materials after sorting during each sorting operation. It can be understood that when the first conveying mechanism transports the mixed recyclables to the intelligent sorting device for sorting, since the first conveying mechanism operates continuously, a portion of the mixed recyclables transported first has already been sorted, but a portion transported later still needs to be sorted. At this time, the remaining materials after the first sorting are temporarily stored in the automated storage bin. After the intelligent sorting device completes all sorting operations in this round, the remaining materials are then cyclically transported back to the first conveying mechanism via the second conveying mechanism for the next round of sorting. This ensures reliable operation of each round of sorting and increases the feed rate, thus improving sorting efficiency.

[0031] It is understood that the intelligent sorting device operates in different modes depending on the number of recyclable material cycles, and the types of recyclable material sorted by the intelligent sorting device differ under different modes. For example, during the first cycle of recyclable material transport, the intelligent sorting device operates in a first mode, which can sort out the first type of recyclable material; during the second cycle, the intelligent sorting device operates in a second mode, which can sort out the second type of recyclable material; and so on, thereby sorting multiple different types of recyclable material into corresponding classification and storage devices during multiple cycles. Of course, in other embodiments of the present invention, the intelligent sorting device can operate in the same mode during two consecutive cycles. For example, when there is a large quantity of a certain type of recyclable material in the mixed recyclable material, it is difficult to sort it all out in one sorting operation. In this case, the intelligent sorting device can be controlled to repeatedly execute the same mode to sort out all the recyclable material of that type.

[0032] Optionally, the intelligent sorting device includes a photoelectric sorter, which corresponds to multiple sorting and storage devices. The photoelectric sorter operates in different modes depending on the number of conveying cycles. During each conveying cycle of recyclables, the photoelectric sorter sorts one type of recyclable into the corresponding sorting and storage device. The number of sorted recyclable types is equal to the number of conveying cycles and the number of sorting and storage devices. Preferably, the photoelectric sorter sorts one type of recyclable material in each operating mode to facilitate refined sorting. For example, one photoelectric sorter corresponds to n sorting and storage devices. During each conveying cycle of recyclables, the photoelectric sorter sorts one type of recyclable into the corresponding sorting and storage device. Through n conveying cycles, the sorting of n types of recyclables can be completed. It is understood that the photoelectric sorter is a photoelectric sorting machine, a mature existing product, and its specific working principle will not be elaborated here.

[0033] Preferably, the intelligent sorting device includes at least two optical sorters. Adjacent optical sorters are connected by a third conveying mechanism for transporting recyclables. Each optical sorter corresponds to the same number of sorting and storage devices. Different optical sorters sort out different types of recyclables in each sorting operation, ensuring that at least two types of recyclables are sorted in one cycle of transport. The number of sorted recyclable types is equal to the product of the number of cycles and the number of optical sorters. The number of cycles is equal to the number of sorting and storage devices corresponding to each optical sorter.

[0034] Specifically, such as Figure 2As shown, in a preferred embodiment of the present invention, the intelligent sorting device includes m optical sorters, each corresponding to n classification and storage devices. Since the optical sorter only sorts out one type of recyclable material in each sorting operation, and the working mode is different for different cycles of conveying, n cycles of conveying are required to complete all sorting operations. Therefore, each optical sorter has n working modes, and the working mode executed by different optical sorters is different each time a sorting operation is performed, that is, different optical sorters sort out different types of recyclable materials. After n cycles of conveying, the number of types of recyclable materials sorted by the intelligent sorting device is n*m. For example, after the first loading, a control mode instruction for the intelligent sorting device is given, which includes sequentially executed control mode 1, control mode 2, ..., control mode n. First, control mode 1 is executed. Light separator 1 sorts PET plastic bottles to recycling bin 1.1, light separator 2 sorts colored ethylene plastic bottles to recycling bin 2.1, and light separator n sorts white ethylene plastic bottles to recycling bin n.1. During the first round of sorting, the remaining materials are temporarily stored in an automated storage bin. After all n light separators have completed their sorting operations, the automated storage bin transports the remaining materials to a second conveying mechanism, which then circulates the remaining materials back to the first conveying mechanism. Next, control mode 2 is executed. Light separator 1 sorts ABS plastic products to recycling bin 1.2, light separator 2 sorts colored propylene PP plastic bottles to recycling bin 2.2, and light separator n sorts transparent PP plastic products to recycling bin n.2. During the second round of sorting... During the sorting process, the remaining materials after sorting are temporarily stored in an automated storage silo. After all n optical sorters have completed their sorting operations, the automated storage silo then transports the remaining materials to a second conveying mechanism, which in turn circulates the remaining materials to the first conveying mechanism. This process continues until control mode n is executed. Optical sorter 1 sorts PVC plastic products to recycling bin 1.n, optical sorter 2 sorts glass products to recycling bin 2.n, and optical sorter n sorts aluminum cans to recycling bin nn. During the nth round of sorting, the remaining materials after sorting are temporarily stored in the automated storage silo. After all n optical sorters have completed their sorting operations, the automated storage silo then transports the remaining materials to the second conveying mechanism, which finally transports the remaining materials to the downstream process. The next time materials are loaded, control mode 1, control mode 2, ..., control mode n are executed sequentially.

[0035] It is understood that the intelligent sorting device in this embodiment uses at least two optical sorters and controls different optical sorters to sort out different types of recyclables in each sorting operation, so as to complete the sorting of at least two types of recyclables in one cycle of conveying, thereby reducing the number of cycles of conveying, improving sorting efficiency, and further improving the degree of fine sorting.

[0036] It is understood that, in another embodiment of the present invention, the intelligent sorting device includes at least one intelligent robot, each intelligent robot corresponding to multiple sorting and storage devices. During each cycle of recyclable material transport, each intelligent robot sorts multiple types of recyclable materials into different sorting and storage devices. The number of sorted recyclable material types is equal to the product of the number of cycles and the number of recyclable material types sorted by the intelligent robot each time. The intelligent robot is a mature existing product; for example, an existing artificial intelligence sorting machine can be used, and its specific working principle will not be elaborated here.

[0037] Specifically, such as Figure 3 As shown, the intelligent robot has n working modes, and in each working mode, it can identify four different types of recyclable materials. After the first loading, the intelligent robot is given control mode instructions, which include sequentially executed control mode 1, control mode 2, ..., control mode n. First, control mode 1 is executed, where the intelligent robot sorts PET plastic bottles to recycling bin 1.1, colored ethylene plastic bottles to recycling bin 2.1, white ethylene plastic bottles to recycling bin 3.1, and ABS plastic products to recycling bin 4.1. During the first round of sorting, the remaining materials are temporarily stored in an automated storage bin. After the intelligent robot completes all sorting operations, the automated storage bin transports the remaining materials to a second conveying mechanism, which then recycles the remaining materials to the first conveying mechanism. Next, control mode 2 is executed, where the intelligent robot sorts colored propylene PP plastic bottles to recycling bin 1.2, transparent PP plastic products to recycling bin 2.2, PVC plastic products to recycling bin 3.2, and glass products to recycling bin 4.2. During the second round of sorting, the remaining materials are temporarily stored in an automated storage bin. After the intelligent robot completes all sorting, the automated storage bin transports the remaining materials to the second conveyor mechanism, which then circulates the remaining materials to the first conveyor mechanism. Finally, control mode n is executed, where the intelligent robot sorts aluminum cans to recycling bin 1.n, iron cans to recycling bin 2.n, cardboard to recycling bin 3.n, and PVC / PET blister packs to recycling bin 4.n. During the nth round of sorting, the remaining materials are temporarily stored in the automated storage bin. After the intelligent robot completes all sorting, the automated storage bin transports the remaining materials to the second conveyor mechanism, which then transports the remaining materials to the downstream process. The next time materials are loaded, control mode 1, control mode 2, ..., control mode n are executed sequentially. It is understood that each intelligent robot executes the same control mode instructions. The more intelligent robots there are, the more recyclable materials of the same type can be sorted in each sorting operation, which is beneficial to improving sorting efficiency. However, it will also increase the space occupied. Therefore, the present invention preferably uses one intelligent robot to perform sorting operations.

[0038] It is understood that the intelligent sorting device in this embodiment uses an intelligent robot, which can sort out multiple types of recyclables in each sorting operation, reducing the number of cyclic transports and improving sorting efficiency.

[0039] In addition, such as Figure 4 As shown, another embodiment of the present invention also provides an intelligent recycling sorting method for recyclable materials after waste sorting, preferably employing the intelligent recycling sorting system described above, which includes the following:

[0040] Step S1: Input the mixed recyclable material into the first conveying mechanism;

[0041] Step S2: Control the intelligent sorting device to sort and recycle the input mixed recyclables, so as to sort different types of recyclables into different classification storage devices, and after each sorting, transport the remaining recyclables to the second conveying mechanism.

[0042] Step S3: Control the second conveying mechanism to circulate and transport the recyclable material to the first conveying mechanism;

[0043] Step S4: Repeat the above process until all types of recyclables have been sorted, then control the second conveyor to transport the remaining material downstream.

[0044] It is understood that the intelligent cyclic sorting method of this embodiment adopts a cyclic conveying method for recyclable materials and controls the intelligent sorting device to execute different working modes each time recyclable materials are conveyed. Through multiple cycles, the sorting operation of all types of recyclable materials can be completed. The sorting process is carried out cyclically, which greatly shortens the length of the sorting production line, thereby greatly reducing the space occupied. Moreover, only one type of sorting equipment needs to be invested, which greatly reduces the investment cost and significantly improves the effective utilization efficiency of the sorting equipment. At the same time, the number and types of recyclable materials sorted out are positively correlated with the number of cyclic conveyings. The more cyclic conveyings, the more types of recyclable materials are sorted out, thus achieving refined sorting and recycling.

[0045] It is understood that the intelligent sorting device operates in different modes depending on the number of recyclable material cycles, and the types of recyclable material sorted by the intelligent sorting device differ under different modes. For example, during the first cycle of recyclable material transport, the intelligent sorting device operates in a first mode, which can sort out the first type of recyclable material; during the second cycle, the intelligent sorting device operates in a second mode, which can sort out the second type of recyclable material; and so on, thereby sorting multiple different types of recyclable material into corresponding classification and storage devices during multiple cycles. Of course, in other embodiments of the present invention, the intelligent sorting device can operate in the same mode during two consecutive cycles. For example, when there is a large quantity of a certain type of recyclable material in the mixed recyclable material, it is difficult to sort it all out in one sorting operation. In this case, the intelligent sorting device can be controlled to repeatedly execute the same mode to sort out all the recyclable material of that type.

[0046] It is understood that, preferably, in step S2, the remaining recyclables after sorting are first transported to an automated storage silo for temporary storage during each sorting operation, and after all sorting operations are completed in each round, the remaining recyclables are then transported to the second conveying mechanism.

[0047] Optionally, the intelligent sorting device includes a light sorter, which corresponds to multiple sorting and storage devices. The light sorter operates in different modes under different cycles of conveying. During each cycle of conveying recyclables, the light sorter sorts one type of recyclable to the corresponding sorting and storage device. The number of types of recyclables sorted out is equal to the number of cycles of conveying and the number of sorting and storage devices.

[0048] Preferably, the intelligent sorting device includes at least two optical sorters, with recyclables being transported between adjacent optical sorters via a third conveying mechanism. Each optical sorter corresponds to the same number of sorting and storage devices. Different optical sorters sort out different types of recyclables in each sorting operation, so that at least two types of recyclables can be sorted in one cycle of conveying. The number of types of recyclables sorted out is equal to the product of the number of cycles of conveying and the number of optical sorters.

[0049] Optionally, the intelligent sorting device includes at least one intelligent robot, each intelligent robot corresponding to multiple classification and storage devices. During each cycle of transporting recyclables, each intelligent robot sorts multiple types of recyclables into different classification and storage devices. The number of types of recyclables sorted out is equal to the product of the number of cycles and the number of types of recyclables sorted by the intelligent robot each time.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
