Description

Technical Field

[0001] The present invention relates to the technical field of automated conveyor belts, and particularly to a grading and sorting conveyor belt. Background Art

[0002] In the fields of logistics, warehousing, and automated production, goods sorting, as the core process connecting upstream and downstream links, directly determines the overall operation efficiency and accuracy. With the increasing demand for flexible production and rapid response in the industry, traditional sorting methods have gradually revealed significant limitations: Although manual sorting can achieve a certain degree of flexibility, it is costly, error-prone, and difficult to adapt to high-intensity and continuous working environments; Fixed mechanical sorting equipment can partially replace manual labor, but it is often limited by problems such as single sorting dimension and poor adjustment flexibility, and it is difficult to meet the compatibility requirements of multi-specification goods. How to break through the bottleneck of existing technologies and achieve efficient, accurate, and multi-specification-compatible automated sorting has become a key challenge restricting industry upgrading.

[0003] In the prior art, some sorting devices attempt to achieve goods grading through a single size threshold. For example, a sorting device and its sorting method for logistics distribution proposed in the patent with the publication number CN119838882A uses a laser profile scanner to identify the size of goods, but its sorting logic can only achieve two-level sorting (such as qualified / unqualified), with a single sorting dimension, and the equipment highly depends on complex electronic systems such as laser scanners and image processing modules, resulting in high costs and complex maintenance; Another type, such as a return supply sorting method, device, and system proposed in the patent with the publication number CN119067555A, although introducing image recognition technology to improve the sorting intelligence level, the sorting efficiency is limited by the image recognition speed, and the system needs to continuously optimize the model to adapt to new product categories, with poor scalability. The above technologies have not solved the balance problem among sorting efficiency, cost, and multi-specification compatibility.

[0004] Based on this, there is an urgent need to propose a new grading and sorting conveyor belt, which realizes the automation and precision of multi-level sorting in a single device through mechanical structure innovation and process optimization, significantly reduces the failure rate and maintenance cost, while reducing sorting deviation, and is compatible with various sizes of goods, providing an efficient, reliable, and economical solution for the logistics sorting field.

Among them, the cross-sections of the pushing parts of the primary pusher device, the secondary pusher device, and the tertiary pusher device and the buffer pad roughly form a circle with the same center and the same radius, and the distance from this circle to the baffle part defines the maximum diameter that the goods can pass through.

[0015] Preferably, conveying guardrails are provided on both sides of the main conveyor belt and the secondary conveyor belt.

Specific embodiments

[0033] The present invention will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 8 shown, the present invention provides a grading and sorting conveyor belt, including a main conveyor belt 1000, a grading and sorting device 2000 provided at one end of the main conveyor belt 1000, and at least two secondary conveyor belts 3000 connecting the grading and sorting device 2000;

[0035] The grading and sorting device 2000 includes a sorting base 2100, a rotating disk device 2200, a grading device 2300, and a feeding device 2400 disposed on the sorting base 2100. The rotating disk device 2200 includes an annular transporting turntable 2210 and a turntable driving device 2220 disposed on the sorting base 2100. The grading device 2300 includes at least one grading baffle 2310 fixedly connected to the sorting base 2100. At least part of the grading baffle 2310 covers the transporting turntable 2210, and the grading baffle 2310 defines the maximum diameter through which the goods can pass. The feeding device 2400 is disposed in the middle of the transporting turntable 2210. The feeding device 2400 includes a clamping and adjusting device 2410 and at least two pushing devices 2500 respectively disposed on both sides of the grading baffle 2310;

[0036] Among them, when the goods are transported from the main conveyor belt 1000 to the rotating disk device 2200, the clamping and adjusting device 2410 clamps the goods to one end of the transporting turntable 2210 close to the axis center. When the goods rotate with the rotating disk device 2200 to the grading baffle 2310, the feeding device 2400 pushes the goods to the corresponding secondary conveyor belt 3000 through different pushing devices 2500 according to whether the size of the goods exceeds the maximum diameter defined by the grading baffle 2310.

[0037] In this embodiment, the main conveyor belt serves as the starting-end conveying equipment of the entire grading and sorting conveyor belt system. The main conveyor belt undertakes the key task of continuously and stably conveying the goods to be sorted from the upstream process or storage area to the grading and sorting device. It is the first link for the goods to enter the grading and sorting process, ensuring that the goods can enter the subsequent sorting operations at a predetermined speed and rhythm.

[0038] Specifically, by reasonably setting the speed, length, and conveying material of the main conveyor belt, it can adapt to the conveying requirements of different types and weights of goods. For example, for lighter and easily damaged goods, a softer conveyor belt material can be used, and the conveying speed can be appropriately reduced to reduce the vibration and collision of the goods during the conveying process; for heavier and larger-volume goods, a conveyor belt with higher strength and stronger bearing capacity can be selected, and the conveying speed can be appropriately increased to improve the overall conveying efficiency.

[0039] In this embodiment, the sorting base 2100 provides a stable installation platform for the rotating disk device 2200, the grading device 2300, and the feeding device 2400. It ensures the relative position accuracy and stability of each component during operation, and avoids the position deviation of the components caused by vibration or external interference, thereby affecting the sorting accuracy and efficiency.

[0040] The conveying turntable 2210, which is annular, is the main component for carrying and conveying goods during the grading and sorting process. The conveying turntable 2210 rotates under the drive of the turntable drive device 2220. After receiving goods from the main conveyor belt 1000, it conveys the goods to the positions of the grading baffle 2310 and the pusher device 2500 in sequence through rotation, realizing the dynamic conveying and sorting operations of the goods.

[0041] The turntable drive device 2220, which is arranged on the sorting base 2100, provides rotational power for the conveying turntable 2210. By precisely controlling the rotation speed and direction of the turntable drive device 2220, it can ensure that the conveying turntable 2210 rotates stably at a predetermined speed and direction, guaranteeing the smoothness and accuracy of the goods during the conveying process. In some embodiments, in some application scenarios with high requirements for sorting accuracy, the turntable drive device 2220 can adopt a high-precision servo motor, combined with an advanced control system, to achieve precise control of the rotation speed and angle of the conveying turntable 2210.

[0042] In this embodiment, the secondary conveyor belt is responsible for receiving the graded goods pushed from the grading and sorting device and conveying the goods to the downstream process or the designated storage area. At least two secondary conveyor belts correspond to different grading levels, realizing the classified conveying of goods of different sizes and providing convenience for subsequent goods handling.

[0043] By reasonably setting the speed, direction and conveying path of the secondary conveyor belt, it can ensure that the graded goods can be accurately and efficiently conveyed to the designated position. For example, in some application scenarios that require rapid processing of a large number of graded goods, multiple parallel secondary conveyor belts can be adopted and equipped with an advanced conveying control system to achieve the efficient and orderly conveying of goods.

[0044] As Figures 3 to 8 shown, in this embodiment, the grading baffle 2310 includes a first-stage baffle 2311 and a second-stage baffle 2312, and the pusher device 2500 includes a first-stage pusher device 2501 arranged on one side of the first-stage baffle 2311, a second-stage pusher device 2502 arranged between the first-stage baffle 2311 and the second-stage baffle 2312, and a third-stage pusher device 2503 arranged on the other side of the second-stage baffle 2312;

[0045] The grading baffle 2310 has a baffle part 2320 and a transition part 2330. The baffle part 2320 defines the maximum diameter through which the goods can pass. Among them, the maximum diameter defined by the first-stage baffle 2311 is greater than the maximum diameter defined by the second-stage baffle 2312.

[0046] In this embodiment, the grading baffle 2310 realizes the grading of goods by defining the maximum diameter through which the goods can pass. At least part of the grading baffle 2310 covers the conveying turntable 2210. When the goods rotate with the conveying turntable 2210 to the grading baffle 2310, if the diameter of the goods is smaller than the maximum diameter defined by the grading baffle 2310, they can pass smoothly; if the diameter of the goods is larger than the maximum diameter defined by the grading baffle 2310, they will be blocked by the grading baffle 2310, thereby triggering the subsequent pusher device 2500 to perform sorting operations.

[0047] Specifically, the grading baffle 2310 includes a first-stage baffle 2311 and a second-stage baffle 2312, and the maximum diameter defined by the first-stage baffle 2311 is larger than the maximum diameter defined by the second-stage baffle 2312. This grading setting can achieve precise grading of goods in different size ranges. For example, in fruit sorting, the first-stage baffle 2311 can be used to sort out larger fruits, the second-stage baffle 2312 can be used to sort out medium-sized fruits, and the smaller fruits that do not pass through the second-stage baffle 2312 can be processed by other means such as subsequent screening or directly conveyed to a specific area. In addition, the grading baffle 2310 has a baffle portion 2320 and a transition portion 2330. The baffle portion 2320 defines the maximum diameter through which the goods can pass, and the transition portion 2330 plays a role in guiding the goods to pass smoothly or be blocked, reducing damage to the goods caused by collision or jamming during the grading process.

[0048] In some embodiments (not shown in the figure), the grading baffle is not limited to including a first-stage baffle and a second-stage baffle, and can also be provided with any desired number of stages such as a third-stage baffle, a fourth-stage baffle, etc.

[0049] As Figure 1 、 Figure 4 、 Figure 5 and Figure 8 shown, in this embodiment, the feeding device 2400 includes a feeding base 2401, and a feeding extension platform 2402 for accommodating the clamping and adjusting device 2410 and the pusher device 2500 is provided on the feeding base 2401. The pusher device 2500 includes a pushing plate 2510 and a driving rod 2520 penetrating through the upper end of the pushing plate 2510. One end of the driving rod 2520 is connected to a driving motor 2530, and the driving rod 2520 and the driving motor 2530 are located in the feeding extension platform 2402;

[0050] Among them, the pushing plate 2510 includes a connecting portion 2511 and a pushing portion 2512. The connecting portion 2511 is provided with a driving hole 2513 for accommodating the driving rod 2520. A first driving thread 2521 is provided on the driving rod 2520, and a second driving thread 2514 corresponding to the first driving thread 2521 is provided in the driving hole 2513. The pushing portion 2512 has an arc-shaped cross section.

[0051] In this embodiment, the feeding base 2401 provides an installation foundation and a support structure for the clamping and positioning device 2410 and the material pushing device 2500, ensuring the position accuracy and stability of each component during the feeding process. At the same time, the feeding base 2401 also plays a role in connecting and integrating each component, enabling the feeding device 2400 to work collaboratively as a whole.

[0052] The feeding extension table 2402 provided on the feeding base 2401 houses the clamping and positioning device 2410 and the material pushing device 2500, providing the necessary operating space and protection for these devices. It enables the clamping and positioning device 2410 and the material pushing device 2500 to work in a relatively independent and stable environment, reducing the impact of external interference on the operation of the devices.

[0053] Specifically, the pushing plate 2510 is a key execution component of the material pushing device 2500, including a connecting portion 2511 and a pushing portion 2512. The connecting portion 2511 is provided with a driving hole 2513 for accommodating the driving rod 2520. The first driving thread 2521 provided on the driving rod 2520 cooperates with the second driving thread 2514 in the driving hole 2513. By rotating the driving rod 2520 through the rotation of the driving motor 2530, the linear motion of the pushing plate 2510 is realized. The pushing portion 2512 has an arc-shaped cross-section, and this design can better match the shape of the goods, reducing damage to the goods during the pushing process and improving the stability and accuracy of the pushing at the same time.

[0054] The driving rod 2520 is arranged through the upper end of the pushing plate 2510, and one end is connected to the driving motor 2530. The driving motor 2530 provides power for the movement of the pushing plate 2510. By precisely controlling the rotation speed and direction of the driving motor 2530, precise control of the movement speed and position of the pushing plate 2510 can be achieved. For example, in some application scenarios with high requirements for sorting speed, a high-performance driving motor 2530 can be used, combined with an advanced driving control system, to achieve fast and accurate movement control of the pushing plate 2510.

[0055] Such as Figures 1 to 4 and Figure 5 and Figure 7As shown, in this embodiment, the clamping and positioning device 2410 includes a positioning device 2411 and a clamping device 2417. The clamping device 2417 includes a clamping arm 2418 and a clamping motor 2419. The positioning device 2411 includes a positioning support 2412 provided on the clamping motor 2419 and a positioning rod 2413 passing through the positioning support 2412. A positioning motor 2414 is connected to one end of the positioning rod 2413. The positioning rod 2413 and the positioning motor 2414 are located in the feeding extension table 2402. Among them, a third driving thread 2415 is provided in the positioning rod 2413, and a fourth driving thread 2416 corresponding to the third driving thread 2415 is provided in the positioning support 2412.

[0056] In this embodiment, the clamping device 2417 includes a clamping arm 2418 and a clamping motor 2419. The clamping arm 2418 realizes the clamping action on the goods under the drive of the clamping motor 2419. By precisely controlling the operation of the clamping motor 2419, the clamping force and clamping position of the clamping arm 2418 can be adjusted to ensure that the goods will not be damaged during the clamping process and can accurately clamp the goods to one end of the conveying turntable 2210 close to the center of the rotating shaft, preparing for subsequent grading and sorting.

[0057] The positioning device 2411 includes a positioning support 2412 provided on the clamping motor 2419 and a positioning rod 2413 passing through the positioning support 2412. A positioning motor 2414 is connected to one end of the positioning rod 2413. The third driving thread 2415 provided in the positioning rod 2413 cooperates with the fourth driving thread 2416 in the positioning support 2412. By rotating the positioning motor 2414 to drive the positioning rod 2413 to rotate, the position of the clamping device 2417 in the horizontal direction is adjusted. This positioning function can ensure that the clamping device 2417 can accurately locate the position of the goods and clamp the goods to the correct position, improving the accuracy and efficiency of sorting.

[0058] As Figure 8 shown, in this embodiment, a buffer pad 2403 corresponding to the clamping and positioning device 2410 is provided on the feeding base 2401. The buffer pad 2403 has an arc-shaped curved surface. Among them, the pushing parts 2512 of the first-level pushing device 2501, the second-level pushing device 2502, and the third-level pushing device 2503 and the cross-section of the buffer pad 2403 generally form a circle with the same center and the same radius, and the distance from this circle to the baffle part 2320 defines the maximum diameter that the goods can pass through.

[0059] In this embodiment, a buffer pad 2403 corresponding to the clamping and positioning device 2410 is provided on the feeding base 2401, and the buffer pad 2403 has an arc-shaped curved surface. The cross-sections of the pushing parts 2512 of the primary pushing device 2501, the secondary pushing device 2502, and the tertiary pushing device 2503 and the buffer pad 2403 generally form a circle with the same center and the same radius, and the distance from this circle to the baffle part 2320 defines the maximum diameter through which the goods can pass. This design can play a role in buffering and positioning. When the goods are pushed to the buffer pad 2403, the buffer pad 2403 can absorb the impact force generated during the pushing process of the goods, reduce the collision and friction between the goods and the device, and at the same time ensure the position stability of the goods during the pushing process, improving the accuracy and reliability of sorting.

[0060] As Figure 3 shown, in this embodiment, conveying guardrails 1100 are provided on both sides of the main conveyor belt 1000 and the secondary conveyor belt 3000. On the sorting base 2100, there are two turntable guardrails 2101 that connect to the conveying guardrails 1100 of the main conveyor belt 1000. The conveying guardrails 1100 of the secondary conveyor belt 3000 connect to the turntable guardrails 2101 or the grading baffle 2310, and the conveying guardrails 1100 of adjacent secondary conveyor belts 3000 connect to the same grading baffle 2310.

[0061] In this embodiment, conveying guardrails 1100 are provided on both sides of the main conveyor belt 1000 and the secondary conveyor belt 3000. On the sorting base 2100, there are two turntable guardrails 2101 that connect to the conveying guardrails 1100 of the main conveyor belt 1000. The conveying guardrails 1100 of the secondary conveyor belt 3000 connect to the turntable guardrails 2101 or the grading baffle 2310, and the conveying guardrails 1100 of adjacent secondary conveyor belts 3000 connect to the same grading baffle 2310. The main function of the conveying guardrails 1100 is to prevent the goods from falling off the conveyor belt during the conveying process and ensure that the goods can run stably along the predetermined conveying path. A reasonably designed conveying guardrail 1100 can improve the safety and stability of goods conveying and reduce the losses and safety hazards caused by the goods falling. For example, in some application scenarios with high requirements for the integrity of goods, conveying guardrails 1100 with a higher height and a stronger material can be used, and the guardrails can be inspected and maintained regularly to ensure that they are always in good working condition.

[0062] As Figures 1 to 5 shown, in this embodiment, a plurality of infrared sensing modules are provided in the feeding base 2401 and are arranged towards the secondary conveyor belt 3000 and the main conveyor belt 1000. Induction holes 2321 corresponding to the infrared sensing modules are provided on both the pushing part 2512 and the buffer pad 2403.

[0063] In this embodiment, a plurality of infrared sensing modules are provided in the feeding base 2401 and are arranged facing the secondary conveyor belt 3000 and the main conveyor belt 1000. Induction holes 2321 corresponding to the infrared sensing modules are provided on both the pushing part 2512 and the buffer pad 2403. The infrared sensing modules are mainly used to detect the position and movement state of the goods, and precise detection of the goods is achieved through the induction holes 2321.

[0064] The infrared sensing modules can real-time feedback the position information of the goods, providing accurate data support for the control of the grading and sorting device 2000. For example, when the infrared sensing modules detect that the goods reach the specified position, the corresponding pushing device 2500 can be triggered to perform a pushing operation to achieve automatic sorting of the goods. At the same time, through the analysis and processing of the data of the infrared sensing modules, the operating state of the grading and sorting device 2000 can also be monitored and adjusted in real time, improving the accuracy and efficiency of sorting.

[0065] As Figures 1 to 3 shown, in this embodiment, a vision recognition device 1200 is covered on the main conveyor belt 1000. A screening material pushing device 1300 is arranged on one side of the vision recognition device 1200, and a screening material conveyor belt 1400 is arranged on the other side of the vision recognition device 1200. The vision recognition device 1200 includes a camera and an intelligent recognition host. Among them, the visual information of the goods collected by the camera is transmitted to the intelligent recognition host, and the intelligent recognition host identifies whether the goods meet the screening range of the grading and sorting device 2000, and pushes the goods that do not meet the screening range of the grading and sorting device 2000 to the screening material conveyor belt 1400 through the screening material pushing device 1300.

[0066] In this embodiment, a vision recognition device 1200 is covered on the main conveyor belt 1000. The vision recognition device 1200 includes a camera and an intelligent recognition host. The camera collects the visual information of the goods and transmits this information to the intelligent recognition host. The intelligent recognition host identifies the goods through advanced image recognition algorithms and judges whether the goods meet the screening range of the grading and sorting device 2000.

[0067] Specifically, the vision recognition device 1200 can achieve rapid and accurate recognition of the goods, improving the intelligent level of grading and sorting. For example, in some sorting scenarios with high requirements for the appearance characteristics of the goods, the vision recognition device 1200 can identify the characteristics of the goods such as color, shape, and size, and compare them with the preset grading standards to accurately judge whether the goods meet the requirements of grading and sorting. For the goods that do not meet the screening range of the grading and sorting device 2000, the vision recognition device 1200 can push them to the screening material conveyor belt 1400 through the screening material pushing device 1300 to achieve automatic screening and classification processing of the goods.

[0068] The screening material pushing device 1300 is used in cooperation with the vision recognition device 1200. When the vision recognition device 1200 identifies that the goods do not meet the screening range of the grading and sorting device 2000, the screening material pushing device 1300 pushes the goods to the screening material conveyor belt 1400. The screening material conveyor belt 1400 is responsible for transporting the non-conforming goods to the designated processing area for further processing or recycling.

[0069] The settings of the screening material pushing device and the screening material conveyor belt achieve the automatic screening and processing of goods that do not meet the grading and sorting requirements, improving the automation degree and processing efficiency of the entire grading and sorting system. For example, on some production lines with high requirements for the quality of goods, the unqualified goods can be separated in time through the screening material pushing device 1300 and the screening material conveyor belt, preventing unqualified goods from entering the subsequent production links and ensuring product quality.

[0070] As Figure 6 and Figure 7 shown, in this embodiment, a base slot 2102 is provided in the sorting base 2100, the turntable driving device 2220 is arranged in the base slot 2102, and a plurality of anti-slip protrusions 2211 are provided on the conveying turntable 2210.

[0071] In this embodiment, a base slot 2102 is provided in the sorting base 2100, and the turntable driving device 2220 is arranged in the base slot 2102. This design can protect the turntable driving device 2220, reduce the influence of the external environment on the turntable driving device 2220, and improve the stability and reliability of its operation. A plurality of anti-slip protrusions 2211 are provided on the conveying turntable 2210, and the anti-slip protrusions 2211 can increase the friction between the goods and the conveying turntable 2210, preventing the goods from sliding during transportation and affecting the sorting accuracy.

[0072] The setting of the base slot 2102 can extend the service life of the turntable driving device 2220 and reduce the maintenance cost. The design of the anti-slip protrusions 2211 can improve the stability of the goods during transportation, reduce the collision and damage caused by the sliding of the goods, and improve the sorting accuracy and efficiency. For example, in some sorting scenarios with high requirements for the surface quality of goods, the anti-slip protrusions 2211 can effectively avoid scratches and damages caused by the sliding of the goods during transportation.

[0073] As Figure 1 and Figure 2 shown, in this embodiment, a warning light 2404 is provided on the feeding extension table 2402. The warning light 2404 is mainly used for alarm prompts when abnormal situations occur during the operation of the grading and sorting device 2000, such as equipment failures, goods jams, sorting errors, etc.

[0074] Specifically, the setting of the warning light 2404 can timely remind the operator to pay attention to the operating state of the equipment, take corresponding measures for handling, and avoid the expansion of faults and greater losses. For example, when the grading and sorting device 2000 fails, the warning light 2404 will flash or emit light of a specific color. The operator can quickly locate the fault position according to the prompt of the warning light 2404, and perform maintenance and handling, thereby improving the reliability and maintainability of the equipment.

[0075] The present invention has many usage scenarios, including but not limited to the following described scenarios:

[0076] In a large logistics center or warehouse, it is used for size grading and sorting of various packaged goods, such as express parcels and commodity packaging boxes of different specifications. According to the size of the goods, they are sorted into different storage areas or transportation channels, so as to improve the efficiency of goods storage and transportation;

[0077] In the processing production line of agricultural products such as fruits and vegetables, size grading and sorting of agricultural products are carried out. For example, fruits such as apples and oranges are divided into different grades according to the diameter size, which is convenient for subsequent packaging, sales and pricing, and meets different market demands;

[0078] In the parts production workshop, size screening of various produced parts is carried out, and the parts that meet different specification requirements are sorted into different assembly lines or storage areas, ensuring the smooth progress of the assembly process and the consistency of product quality;

[0079] When an e-commerce enterprise processes a large number of orders, the grading and sorting conveyor belt can quickly sort the goods into different order packaging areas according to the size of the goods, improve the order processing speed and shipping efficiency, and enhance customer satisfaction;

[0080] In the food packaging link, sorting of food packages of different specifications, such as canned food and biscuit boxes, is carried out. According to the size, they are allocated to different packaging production lines or storage shelves, which is convenient for subsequent warehousing management and sales distribution.
