Description

Technical Field

[0001] The present invention relates to the technical field of material sorting devices, and in particular to a material sorting system. Background Art

[0002] In the related technology, the channel type color sorter identifies the material when it leaves the channel structure supporting its movement and is in a suspended state, and uses a spray valve to blow and sort the material according to the identification result. Since the material is in the air, it can only be divided into good and bad materials after blowing, and enter the corresponding hopper for collection. In addition, there is a certain carry-out ratio in the air blowing sorting, and the collected materials cannot be sorted again according to the identification results in the air, so it can only be sorted once. It is generally used for products such as grain and rice, and cannot meet the needs of multi-level sorting.

[0003] Some color sorters use a transparent conveyor belt to drive the material through the identification area. Identification cameras are set on both sides of the conveyor belt to detect and identify the material. However, the surface of the transparent conveyor belt is easily dirty, which may lead to misjudgment of the material identification results.

[0004] Some color sorters also use conventional conveyor belts to transport materials and make the materials roll on the surface of the conveyor belt, so as to identify and judge the grade of the materials multiple times. Since the position of the materials on the conveyor belt is relatively stable after identification, accurate multi-level sorting can be performed. However, this method is only suitable for materials with relatively regular surfaces that can roll. Summary of the invention

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The material sorting system 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] Reference Figure 1 According to an embodiment of the present invention, a material sorting system 100 includes: a sorting component 10, an identification component 20, a buffer component 30 and a control component.

[0043] The sorting component 10 includes a first conveying structure 11 and a sorting structure 12. The first conveying structure 11 is used to transport materials. The identification component 20 includes a second conveying structure 21 and a first identification structure 22. The second conveying structure 21 is suitable for supplying materials to the first conveying structure 11. The second conveying structure 21 is provided with a notch 211. The first identification structure 22 performs multi-angle identification of the circumference of the material passing through the notch 211 to obtain the first identification information of the material. The buffer component 30 can be movably arranged at the end of the second conveying structure 11. The control component controls the sorting structure 12 to perform a sorting operation on the material according to the first identification information.

[0044] It should be noted that the material sorting system 100 is usually used to process a large amount of materials. The materials can be fruits or nuts, such as walnut kernels, almonds, pistachios, etc., or other agricultural products, such as pepper, star anise, chili, etc. The material sorting system 100 realizes accurate classification of materials according to preset standards, and can use the sorting structure 12 on the first conveying structure 11 to perform multiple grading and rejection operations on the materials based on the recognition results of the first recognition structure 22 according to product requirements, so as to meet the requirements of efficient and refined grading.

[0045] Among them, the second conveying structure 21 conveys the material to the first conveying structure 11, the first identification structure 22 obtains the first identification information of the material, and the first identification information is transmitted to the control component. When the material moves to the first conveying structure 11, the control component controls the sorting structure 12 adjacent to the first conveying structure 11 to operate the material, and the materials with the same or similar first identification information are collected together, thereby classifying a large amount of material into multiple categories.

[0046] Specifically, the first identification information is information on the surface or inside of the material, including but not limited to the following information: material size information, material surface spot information, material surface texture information, material surface or inside mold information, material material information, etc., among which material surface defects can generally be detected using conventional visible light cameras, and some special information requires the use of special cameras such as hyperspectral, infrared, and ultraviolet light for detection and identification.

[0047] Among them, the first identification structure 22 can be a camera, a camera, or other optical elements; the first identification structure 22 is equipped with a light source, and the light source is one or more of visible light, infrared light, hyperspectral light, ultraviolet light, and X-ray. Generally, it should include at least a visible light camera, and other cameras should be configured according to specific needs, and a suitable optical system should be adaptively built according to needs. The specific optical system will not be repeated in this embodiment.

[0048] In the related art, the channel-type color sorter identifies the material when it leaves the structure supporting its movement and is in a suspended state, and the bad material is blown away by the gas. Since the material moves in the air for a long time after leaving the channel or returns to the channel, the movement state will be uncontrollable. Therefore, the material identification and sorting can only be completed within a very limited window period. Generally, there is only one chance for sorting. At this time, in order to ensure the sorting effect, the pressure of the nozzle used for rejection will be increased to a certain extent, resulting in a certain carry-out ratio, that is, there will be some good materials among the bad materials taken out, which means that the material can only be sorted once and multi-stage sorting cannot be performed; some color sorters use a transparent conveyor belt to drive the material through the identification area, and identification cameras are respectively set on both sides of the conveyor belt to detect and identify the material, but the surface of the transparent conveyor belt is easily dirty, resulting in misjudgment of the material identification result.

[0049] In the embodiment of the present invention, the first identification structure 22 performs multi-angle identification of the circumference of the material at the notch 211. For example, the identification structure of the channel type color sorter can be referred to, and the front and rear sorting boxes are respectively set on both sides of the notch 211 for multi-angle identification to basically cover the entire surface of the material. For example, optical detection is performed on the front half surface and the back half surface of the material respectively, which can basically cover the side of the material and obtain accurate product classification information. Thereby, the overall identification accuracy of the material is improved, and it is convenient to accurately judge the material. At the same time, when the material is in the first conveying structure 11, the sorting structure 12 is controlled to perform operations on the material according to the first identification information obtained, and multiple sorting can be performed, so that the material classification is more accurate, and the product quality and added value are improved.

[0050] Specifically, there are at least two first identification structures 22, and the first identification structures 22 are provided on opposite sides of the gap 211. When the material passes through the gap 211, the first identification structures 22 on both sides respectively obtain information of the material at multiple angles, and the amount of information obtained is greater. Among them, the material has a certain initial speed, so that the material can pass through the gap 211 smoothly.

[0051] For example, refer to Figure 1 The second conveying structure 21 is arranged horizontally, and has a certain initial speed when reaching the gap 211, and is thrown out from the end of the second conveying structure 21, and passes through the gap 211 under the action of inertia; or, the front side of the gap 211 is arranged obliquely upward, and the material moves from front to back, and has a certain initial speed when reaching the gap 211, and passes through the gap 211 to the back side of the gap 211 under the action of inertia; or, the second conveying structure 21 is arranged obliquely downward, and the material can also be thrown from the front side of the gap 211 through the gap 211 to the back side of the gap 211 under the action of inertia.

[0052] More specifically, at least two first identification structures 22 are respectively arranged on the side of the notch 211 close to the sorting component 10 and the side away from the sorting component 10, thereby forming a front and rear sorting box structure. The specific positions of the two first identification structures 22 relative to the notch 211 can be adaptively set according to the identification requirements, such as being respectively arranged on both sides of the notch 211 in the horizontal direction, the up and down direction, or the diagonal direction, to obtain information on the two relative sides of the material.

[0053] It should be noted that a buffer component 30 is also provided at the end of the second conveying structure 21. It can be understood that the material has a certain speed when passing through the gap 211. The present invention provides a certain buffer for the material by setting the buffer component 30 to prevent the material from being deformed or damaged due to impact force, thereby improving the accuracy of sorting. Based on the action of the buffer component 30, the movement speed of the material falling onto the first conveying structure 11 is reduced, so that the material can be smoothly transferred to the first conveying structure 11 to prevent the order and position from being disordered, so that multiple grading and sorting operations can be accurately performed on the material on the first conveying structure 11 through one-time identification at the gap 211.

[0054] According to the material sorting system 100 of the embodiment of the present invention, multi-angle recognition is performed and more surface information is obtained, thereby improving the overall recognition accuracy of the material and the accuracy of the judgment. At the same time, when the material is in the first conveying structure 11, the sorting structure 12 is controlled to perform operations on the material according to the obtained first recognition information, and multiple sortings can be performed, so that the material classification is more accurate, and the product quality and added value are improved. At the end of the second conveying structure 21, a buffer component 30 is provided to match the design of the notch 211 to provide a certain buffer for the material to avoid deformation or damage of the material due to impact force, thereby further improving the accuracy of sorting, and at the same time, it is adaptable to materials with irregular surfaces and increases the scope of application.

[0055] Reference Figure 2 In some embodiments, the second conveying structure 21 includes: a first conveying member 212 and a second conveying member 213 .

[0056] The first conveying member 212 is used to transport materials. The second conveying member 213 is arranged obliquely between the first conveying member 212 and the first conveying structure 11, and the first conveying member 212 and the second conveying member 213 jointly define a gap 211. The material is thrown out from the end of the first conveying member 212 through the gap 211 and transferred to the second conveying member 213, and the buffer assembly 30 is arranged between the second conveying member 213 and the first conveying structure 11.

[0057] In some specific embodiments, the second conveying member 213 is arranged obliquely downward to guide the material to the first conveying structure 11, the first conveying member 212 is arranged on the side of the second conveying member 213 away from the first conveying structure 11, and the end of the first conveying member 212 is higher than the second conveying member 213 to throw the material onto the second conveying member 213.

[0058] The first conveying member 212 is located on the side of the second conveying member 213 away from the first conveying structure 11 , and the end of the first conveying member 212 is higher than the second conveying member 213 . The first conveying member 212 throws the material onto the second conveying member 213 , and the second conveying member 213 transports the material to the first conveying structure 11 .

[0059] In the above scheme, by setting the second conveying member 213 to extend obliquely upward relative to the first conveying structure 11, the second conveying member 213 can better receive the material thrown into the air. It can be understood that the tangential speed of the material can be set to be the same or similar to the inclination angle of the second conveying member 213, thereby reducing the impact force of the material falling on the second conveying member 213 and reducing the probability of material damage.

[0060] Specifically, the second conveying member 213 extends in the direction of the first conveying member 212. The second conveying member 213 can be constructed as a first slide, which is arranged obliquely downward. The material on the first slide automatically slides onto the second conveying member 213. The second conveying member 213 can also be constructed as a conveyor belt. The conveyor belt can be horizontally arranged. The horizontally arranged conveyor belt allows the material to have a certain speed and throw the material into the air. The conveyor belt can also be inclined. The inclined conveyor belt allows the material to have a certain speed and also throw the material into the air.

[0061] Reference Figure 2 In some embodiments, the first conveying member 212 is configured as a first slideway inclined downward.

[0062] Specifically, the first slideway extends along the extension direction of the second conveying member 213 so that the material falls tangentially to the second conveying member 213 .

[0063] The first slide extends along the extension direction of the second conveying member 213 , and the material slides downward on the first slide. The falling material passes through the notch 211 and falls tangentially onto the second conveying member 213 .

[0064] In the above scheme, by setting the first slide to extend along the extension direction of the second conveying member 213, the material can fall tangentially onto the second conveying member 213, thereby reducing the impact force of the material falling on the second conveying member 213, reducing the probability of material damage, simplifying the overall structure, and reducing costs.

[0065] It can be understood that the first slideway does not need to strictly correspond to the second conveying member 213 , and the first slideway may have a slight angle difference with the extension direction of the second conveying member 213 .

[0066] In other embodiments, the first conveying member 212 is configured as a horizontally arranged conveyor belt, which drives the material and throws the material to the second conveying member 213 .

[0067] The conveyor belt is an active driving structure, which drives the material to move and transports the material to the second conveying member 213 .

[0068] In the above solution, by constructing the first conveying member 212 as a conveyor belt, which is an actively driven structure, the overall efficiency is improved and the probability of the material falling from the gap 211 is reduced.

[0069] Specifically, the conveyor belt can be arranged horizontally, and the horizontally arranged conveyor belt enables the material to have a certain speed and throw the material into the air.

[0070] In other embodiments, the conveyor belt may also be arranged at an angle. The inclined conveyor belt allows the material to have a certain speed and can also throw the material into the air.

[0071] Reference Figure 3 , Figure 4 In some embodiments, the material sorting system 100 further includes: a hopper 50 and a vibration assembly 60 .

[0072] The hopper 50 has a feed port 51 and a discharge port 52, wherein the feed port 51 is used to supply materials to the hopper 50. The vibration assembly 60 is disposed between the discharge port 52 and the second conveying structure 21 to vibrate and disperse the materials and then supply them to the second conveying structure 21. The discharge port 52 is provided with an adjustable baffle 53, which is movably disposed at the discharge port 52 to adjust the size of the discharge port 52.

[0073] The material enters the hopper 50 from the feed port 51 and is discharged from the discharge port 52 to the outside of the hopper 50 . The material first passes through the vibration component 60 , which vibrates to evenly disperse the material and then moves it to the second conveying structure 21 .

[0074] In the above scheme, the vibration assembly 60 is provided to disperse the material so that the material is uniform, thereby facilitating subsequent identification and sorting, and improving sorting accuracy. At the same time, an adjustable baffle 53 is provided at the discharge port 52, and the adjustable baffle 53 controls the size of the discharge port 52, thereby limiting the outflow speed of the material, and then adjusting the arrangement and stacking of the material, which can avoid the stacking of the material and further make the material flow out uniformly.

[0075] Specifically, the vibration assembly 60 includes a vibration plate and a vibration motor, and the vibration motor is connected to the vibration plate to drive the vibration plate to vibrate. More specifically, there are multiple vibration plates, and the multiple vibration plates are arranged in sequence, and the heights of the multiple vibration plates decrease in sequence to improve the uniformity effect.

[0076] Specifically, the adjustable baffle 53 can be configured to be adjustable up and down, or to be adjustable left and right. The above solutions can control the size of the discharge port 52, thereby limiting the outflow speed of the material.

[0077] More specifically, the discharge port 52 is constructed as a necking structure, and the necking structure is tilted downward, so that the material can flow more smoothly.

[0078] Reference Figure 4 , Figure 5 and Figure 7 In some embodiments, the material sorting system 100 further includes: a feeding assembly 70, the feeding assembly 70 is disposed between the second conveying structure 21 and the vibration assembly 60, the feeding assembly 70 is provided with a receiving groove 71, the receiving groove 71 is suitable for accommodating a preset amount of material, and the receiving groove 71 is configured to move between the second conveying structure 21 and the vibration assembly 60 to transport the material to the second conveying structure 21. A second slide 72 is disposed between the feeding assembly 70 and the vibration assembly 60, and a first buffer curtain 721 is disposed at the slide exit.

[0079] The feeding assembly 70 is located downstream of the vibration assembly 60. After being vibrated and dispersed by the vibration assembly 60, the material falls into the receiving groove 71. The receiving groove 71 transports the material to the second conveying structure 21. The second slide 72 is arranged between the feeding assembly 70 and the vibration assembly 60. The second slide 72 plays the role of an intermediate bridge to transport the material from the vibration assembly 60 to the feeding assembly 70.

[0080] In the above scheme, a accommodating groove 71 is provided to accommodate the material, and the material accommodated in the accommodating groove 71 is a preset amount, so that the material is further evenly divided, which is convenient for subsequent sorting, and a second slide 72 is provided to make the material neat. At the same time, a first buffer curtain 721 is provided at the slide outlet, and the first buffer curtain 721 is used to reduce the impact of the material and avoid collision damage of the material.

[0081] Specifically, the accommodating groove 71 is suitable for accommodating a preset amount of material, and the preset amount can be based on quantity. For example, the accommodating groove 71 is suitable for accommodating a single walnut, or the accommodating groove 71 is suitable for accommodating two walnuts. It can also be based on volume, which will not be repeated here.

[0082] Specifically, the slide entrance of the second slide 72 is higher than the slide exit, which facilitates transportation.

[0083] Reference Figure 4 , Figure 5 and Figure 7 In some specific embodiments, the second slide 72 is adjacent to a dust blowing cavity 722 , and the dust blowing cavity 722 corresponds to the output position of the vibration component 60 , so as to blow air and remove dust from the output position of the vibration component 60 .

[0084] Specifically, the receiving groove 71 is set according to the size and shape of the material. Figure 4 , Figure 7, a plurality of rows of receiving grooves 71 are evenly arranged on the feeding assembly 70 (for the convenience of observation, only part of the receiving grooves 71 are shown in the figure, and the other receiving grooves 71 are hidden), the feeding assembly 70 is arranged in the horizontal direction, the feeding assembly 70 includes chain rings 73 on both sides of the conveying direction, and the chain rings 73 on both sides are connected by connecting rods 74, the connecting rods 74 are evenly arranged along the loop formed by the chain rings 73, the connecting rods 74 are fixed with wedge blocks 75, the surface of the wedge blocks 75 forms a conical protrusion, and receiving grooves 71 are formed between the protruding positions of adjacent wedge blocks 75, wherein the shape of the protrusion can be arbitrary, and the receiving groove 71 can also be a concave space formed by the surface settlement of the wedge blocks 75.

[0085] Reference Figure 4 , Figure 7 Furthermore, the feeding assembly 70 further includes a scraper 77, which is horizontally arranged above the receiving groove 71 and inclined relative to the conveying direction, and is used to scrape the over-stacked materials from the receiving groove 71 and collect them from the gap between the adjacent connecting rods 74, and finally return them to the hopper 50. A receiving belt 76 is arranged below the scraper 77 in a vertical direction of conveying to output and collect the scraped materials.

[0086] In other embodiments, a conveyor belt is provided between the second conveying structure 21 and the vibration assembly 60 to transport materials from the vibration assembly 60 to the second conveying structure 21 , which has a simple and practical structure.

[0087] In some embodiments, the buffer component 30 has a first position and a second position. When the buffer component 30 is at the first position, the buffer component 30 blocks the moving path of the material. When the buffer component 30 is at the second position, the moving path is released.

[0088] Among them, the buffer component 30 can be movably arranged at the end of the second conveying structure 21. The buffer component 30 is located at the first position, the buffer component 30 is on the moving path of the material, the buffer component 30 exerts a buffering effect and absorbs the impact of the material. The buffer component 30 is located at the second position, the buffer component 30 is away from the moving path, wherein the buffer component 30 can be pushed away by the material or driven away from the moving path by other driving forces, and the material is detached from the first conveying structure 11.

[0089] In the above solution, by providing the buffer component 30 that switches between the first position and the second position, the buffer effect is improved compared with the solution of the buffer curtain in the related art.

[0090] Reference Figure 6 In some embodiments, the buffer assembly 30 includes: a rotating member 31 and a buffer member 32 .

[0091] The rotating member 31 is rotatably disposed at the end of the second conveying structure 21 . The buffer member 32 is disposed at the rotating end of the rotating member 31 and at a side of the rotating member 31 facing the second conveying structure 21 .

[0092] The buffer member 32 is disposed on a side of the rotating member 31 facing the second conveying structure 21 . When the buffer assembly 30 is located at the first position, the front side of the buffer member 32 faces the direction in which the material falls, thereby providing a buffering effect.

[0093] In the above scheme, the rotating member 31 cooperates with the buffer member 32 to realize automatic return in a rotating manner, which is convenient for realizing reciprocating cycles and simplifies the structure.

[0094] Specifically, the rotating member 31 may be made of a hard plate material for easy molding.

[0095] Specifically, the buffer member 32 may be constructed as a flexible buffer layer, such as an elastic rubber layer, or may be constructed as a plurality of flexible wires arranged in an array to provide a certain buffering capacity.

[0096] Reference Figure 6 In some specific embodiments, there are multiple rotating members 31, and the multiple rotating members 31 are connected and rotate around the same rotating axis. There are multiple buffer members 32, and the buffer members 32 are arranged corresponding to the rotating members 31. In the rotation direction of the rotating members 31, the multiple buffer members 32 are arranged on the same side of the corresponding rotating members 31.

[0097] The plurality of rotating members 31 are associated and rotate around the same rotation axis, that is, the plurality of rotating members 31 rotate synchronously or remain stationary, the rotating members 31 can rotate clockwise or counterclockwise, and the plurality of buffer members 32 are located on the same side of the corresponding rotating members 31 .

[0098] In the above scheme, by setting up multiple associated rotating parts 31, the corresponding buffer parts 32 can contact different materials in turn to avoid direct passage of materials through the rotating gap, and shorten the stroke of a single rotating part 31 while realizing the reciprocating rotation of the rotating part 31, thereby improving work efficiency.

[0099] For example, there are two rotating members 31 and two buffer members 32, and the two buffer members 32 are correspondingly arranged on the rotating members 31, and the two rotating members 31 are arranged on opposite sides of the rotating shaft, and in the clockwise direction, the two buffer members 32 are located on the same side of the corresponding two rotating members 31; or, there are three rotating members 31, and the interval between two adjacent rotating members 31 is 120 degrees, and there are three buffer members 32, and the three buffer members 32 are correspondingly arranged on the rotating members 31, and in the clockwise direction, the three buffer members 32 are located on the same side of the corresponding two rotating members 31. Of course, there can be more rotating members 31, which will not be described in detail here.

[0100] In some embodiments, the buffer assembly 30 has the inertia to rotate to the first position to stop the material, and the first conveying structure 11 is provided with a plurality of separation spaces 112 , and the buffer assembly 30 releases the material into the separation spaces 112 in sequence.

[0101] Among them, the space on the first conveying structure 11 is divided into multiple separation spaces 112, and the materials are relatively independent. At the same time, the buffer component 30 stops the material and blocks the material on the second conveying structure 21. The first conveying structure 11 cooperates with the rotating part 31, and the rotating part 31 blocks and releases the material, and transports the material regularly to the separation space 112.

[0102] In the above solution, the materials are arranged regularly and orderly through the cooperation between the rotating member 31 and the first conveying structure 11 .

[0103] Specifically, the rotating member 31 may be stationary in the first position due to its own weight. For example, in the absence of external force, the rotating member 31 automatically droops and stops the material under the action of its own weight. The rotating member 31 may also be stationary in the first position due to the action of a torsion spring and stop the material under the elastic force of the torsion spring. The rotating member 31 may also be stationary in the first position due to the action of a control motor, and the control motor is provided with an electromagnetic brake to stop the material.

[0104] The rotating member 31 is driven to rotate to the second position by an external mechanism, such as a motor, to release the material into the separation space 112. In subsequent grading operations, it can ensure that the material in the specific separation space 112 is removed, completely avoiding the carrying out of other materials, and ensuring accurate grading operations.

[0105] In some specific embodiments, the rotating member 31 is rotatably disposed on the support base. An elastic member is further disposed on the support base. The elastic member is connected to the rotating member 31 so that the rotating member 31 has the inertia to rotate to the first position.

[0106] Specifically, the elastic member may be a torsion spring, one end of which is connected to the support base, and the other end of which is connected to the rotating member 31 . The torsion spring applies a force to the rotating member 31 , so that the rotating member 31 has the inertia to rotate to the first position.

[0107] In other embodiments, the rotating member 31 includes a mounting portion and a counterweight portion.

[0108] The buffer member 32 is mounted on the mounting portion. The counterweight portion is located on a side of the mounting portion away from the buffer member 32, so that when the buffer assembly 30 is located at the first position, the center of gravity of the buffer assembly 30 is located at the lowest point.

[0109] Among them, the counterweight part is located on the side of the mounting part away from the buffer part 32, so as to balance the overall weight of the buffer assembly 30, so that when the buffer assembly 30 is in the first position, the center of gravity of the buffer assembly 30 is located at the lowest point, and when the buffer assembly 30 is in the second position, it is affected by its own gravity and the weight automatically moves to the lowest point, and the buffer assembly 30 automatically returns to the first position.

[0110] In the above solution, the return to the original position is achieved by the deadweight of the rotating member 31, which has a simple structure and reduces the number of parts.

[0111] Reference Figure 6 In some embodiments, a plurality of partitions 111 are provided on the first conveying structure 11, and the plurality of partitions 111 are arranged at intervals along the extension direction of the first conveying structure 11, and two adjacent partitions 111 jointly define a separation space 112, and the separation space 112 is used to accommodate materials. Among them, the buffer assembly 30 has the inertia of rotating to the first position to stop the material, the rotating member 31 has a matching portion, and the partition 111 has a pushing portion, and the pushing portion cooperates with the matching portion to rotate the buffer assembly 30 to the second position.

[0112] Among them, multiple partitions 111 divide the space into multiple separated spaces 112, the materials are relatively independent, convenient and accurate grading operation, and other materials are avoided from being brought out. At the same time, a pushing part is provided on the partition 111, and the matching part has a matching relationship with the matching part on the rotating member 31. The pushing part contacts the matching part and applies a force to the matching part, thereby pushing the buffer assembly 30, and the buffer assembly 30 is usually located in the first position. The buffer assembly 30 switches from the first position to the second position, and the material is transferred from the first conveying structure 11 to the separated space 112.

[0113] In the above scheme, a plurality of separation spaces 112 are separated by setting a partition 111, and the separation spaces 112 are used to independently transport materials, thereby reducing problems such as material errors and contact, and avoiding the problem of other materials being carried out synchronously, thereby improving the accuracy of material sorting. In addition, the partition 111 cooperates with the rotating part 31, and the rotating part 31 does not need to be equipped with an additional driving device, thereby simplifying the structure and reducing the occupied space.

[0114] It should be noted that the buffer assembly 30 has the inertia to rotate to the first position. When the pushing portion does not contact the mating portion, the buffer assembly 30 automatically returns to the first position, thereby stopping the material. The buffer assembly 30 may automatically return under the influence of its own gravity, or may automatically return by being connected to an elastic member.

[0115] In other embodiments, the buffer assembly 30 further includes: a control motor, the output end of the control motor is connected to the rotating member 31, and the control motor is provided with an electromagnetic brake, which is connected to the output end to lock the output end when the control motor stops working.

[0116] The output end of the control motor is connected to the rotating member 31 to actively drive the rotating member 31 to rotate. The output end is connected to an electromagnetic brake. When the control motor stops working, the output end cannot rotate and the rotating member 31 is stationary.

[0117] In the above scheme, by setting a control motor to actively drive the rotating member 31 to rotate, and providing an electromagnetic brake to lock the output end, the rotating member 31 can be fixed in one position, for example, the buffer assembly 30 is stationary in the first position, so that the falling material is stationary on the second conveying structure 21, thereby improving work efficiency.

[0118] In some embodiments, the material sorting system also includes a second identification structure, which is used to obtain second identification information of the material on the first conveying structure 11, and the second identification structure is electrically connected to the control component, which controls the sorting structure 12 to operate the material according to the first identification information and the second identification information, such as pushing the material into the corresponding collecting component 121 or other operations.

[0119] Among them, the second identification structure is used to obtain the second identification information, the second identification structure is electrically connected to the control component, and the control component controls the sorting structure 12 to operate the material according to the first identification information and the second identification information. The control component can compare the first identification information with the second identification information to avoid problems such as sequence changes and material stacking when the material falls through the gap 211; at the same time, the control component can determine whether multiple materials are stacked through the second identification information, which may cause the subsequent separation space 112 to contain materials exceeding the preset amount, resulting in carry-over problems and reducing the sorting accuracy.

[0120] In the above scheme, by setting a second identification structure to obtain second identification information, the control component controls the sorting structure 12 to operate the material according to the first identification information and the second identification information, thereby avoiding problems such as sequence changes and material stacking when the material falls through the gap 211, while avoiding carry-out problems and improving the sorting accuracy.

[0121] Specifically, the second identification information includes morphological information of the material, such as shape, color, size, etc.

[0122] Specifically, in the subsequent sorting process, the materials that fail to match the sequential material morphology information will not be sorted and will be returned to the hopper 50 .

[0123] Reference Figure 4 , Figure 8 In some embodiments, the sorting structure 12 includes: a plurality of collecting components 121 and operating components 122 .

[0124] The plurality of collecting members 121 are sequentially distributed along the transport direction of the first conveying structure 11. The operating member 122 is adjacent to the first conveying structure 11, and is electrically connected to the control member, and exerts force on the material under the control of the control member, so as to collect the materials of the same grade into the same collecting member 121.

[0125] The grade of the material is determined based on the recognition result of the material sorting system. Specifically, the classification grade of the material can be determined based on the first recognition information, and the material can be inspected based on the second recognition information to ensure that the material transportation order is consistent with the recognition order of the first recognition structure.

[0126] It is also possible to use the second identification information to verify the order of materials and comprehensively determine the grade of the materials based on the first identification information and the second identification information. The specific classification standards are adjusted according to the differences and needs of the materials, such as size, surface texture, color, moisture content, etc., or a single or comprehensive factor for judgment.

[0127] The inlets of the plurality of collecting members 121 are sequentially distributed along the transport path of the first conveying structure 11, and the operating member 122 acts toward the inlet of the collecting member 121 to sort the materials of the corresponding level into the corresponding collecting member 121. When the materials move to the corresponding collecting member 121, the operating member 122 applies force to the materials to transfer the materials into the collecting member 121.

[0128] In some embodiments, a collecting piece 121 is further provided at the output end of the first conveying structure 11. The collecting piece 121 here is used to collect materials that have not been successfully graded, such as materials that cannot effectively correspond to the recognition results of the first recognition structure after detection by the second recognition structure, or multiple materials are stacked together, or materials that cannot be effectively identified, etc., and these materials can be re-provided to the material sorting system for grading and sorting.

[0129] In the above scheme, a large amount of materials are divided into multiple categories by cooperating with the operating member 122 and the plurality of collecting members 121, and the materials are further subdivided, thereby achieving refined sorting of products.

[0130] For example, the category is level, and there are at least three collecting pieces 121, a large amount of materials are divided into three levels, and the three collecting pieces 121 collect materials of different levels respectively; or, there are four or more collecting pieces 121, which will not be repeated here.

[0131] Specifically, the operating member 122 can be a nozzle that sprays gas to the material and transfers the material to the collecting member 121; or, the operating member 122 can be a push rod that applies thrust to the material and pushes the material into the collecting member 121; or, the operating member 122 can be a manipulator that grabs the material and transfers the material to the collecting member 121.

[0132] Specifically, a plurality of operating members 122 may be provided, and the operating members 122 correspond one to one with the collecting members 121; or, the number of operating members 122 is less than the number of collecting members 121, and a single operating member 122 corresponds to a plurality of collecting members 121, and the operating member 122 may be moved to complete the operation.

[0133] In other embodiments, the plurality of collecting members 121 are movable, and the collecting members 121 are moved to the corresponding materials to collect the materials.

[0134] In some specific embodiments, the operating member 122 is configured as any one of an air nozzle and a push rod.

[0135] Among them, the operating part 122 can be an air nozzle or a push rod. When the operating part 122 is an air nozzle, the air nozzle sprays gas on the material to push the material to move. When the operating part 122 is a push rod, the push rod pushes the material to move. The implementation method is simple and practical.

[0136] In some embodiments, the operating member 122 is configured to be movable to a position corresponding to a material and exert force on the material to collect the material into the corresponding collecting member 121 .

[0137] The operating member 122 is adjacent to the first conveying structure 11 , and the operating member 122 can be moved to a position corresponding to the material and exert an action on the material to transfer the material to the corresponding collecting member 121 .

[0138] In the above solution, by providing a movable operating member 122, the operating member 122 corresponds to a plurality of collecting members 121, and the plurality of collecting members 121 share the same operating member 122, thereby reducing the number of components and optimizing the structure.

[0139] In other embodiments, there are multiple operating members 122 , and the operating members 122 are disposed corresponding to the collecting members 121 to exert force on the materials and collect the materials into the corresponding collecting members 121 .

[0140] The collecting member 121 corresponds to the operating member 122 one by one. When the material moves to the corresponding collecting member 121 , the corresponding operating member 122 is actuated to transfer the material to the corresponding collecting member 121 .

[0141] In the above solution, by providing a plurality of operating members 122 , the operating members 122 correspond to the collecting members 121 one by one, thereby improving the accuracy of sorting and reducing the probability of misoperation of the operating members 122 .

[0142] Reference Figure 4 , Figure 8More specifically, the operating member 122 corresponds to the middle position of the first conveying structure 11, so that the corresponding collecting member 121 can be arranged on the opposite sides of the first conveying structure 11, making the overall structure more compact.

[0143] Furthermore, multiple collecting members 121 corresponding to the same first conveying structure 11 are arranged in an interlaced manner, so that the structure is more compact. Correspondingly, there are gaps between the multiple first conveying structures 11 to accommodate the collecting members 121 and the operating members 122, and each operating member 122 can apply force to the first conveying structures 11 on both sides respectively. For example, the operating member 122 is a nozzle, and the first nozzle sprays air to the left to act on the material on the first conveying structure 11 on the left, and the adjacent second nozzle sprays air to the right to act on the right side of the first conveying structure 11 to collect the material. It can be understood that in the extension direction of the first conveying structure 11, the arrangement of the first nozzle and the second nozzle can be repeated.

[0144] In some specific embodiments, the first conveying structure 11 is configured as a belt structure; in other embodiments, the first conveying structure 11 is configured as a conveyor disc structure. Of course, there are other situations, which will not be described here.

[0145] In some specific embodiments, there are multiple first conveying structures 11, and the multiple first conveying structures 11 are arranged in parallel, so as to improve the sorting efficiency.

[0146] Reference Figure 4 , Figure 8 Specifically, the collecting member 121 is a collecting hopper. The first conveying structure 11 is adjacent to a receiving barrel 113 for receiving materials. A receiving belt 114 perpendicular to the first conveying structure 11 is provided below the receiving barrel 113 to collect the sorted materials from the side and can collect materials on multiple parallel first conveying structures 11 at the same time. A dividing belt can be provided on the surface of the receiving belt 114 as needed. The dividing belt extends in a direction perpendicular to the first conveying structure 11, and its surface is divided into multiple material conveying channels, so that multiple levels of materials can be conveyed at the same time, and different collecting hoppers are used to collect them at the end of the conveying. Materials that cannot be effectively identified or have special circumstances such as piles are collected from the end along the first conveying structure 11, and then returned to the hopper 50 through a hoist or manual operation for re-grading.
