The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] The embodiment of the present invention provides a sorting device for sorting small materials (such as chips), such as Figure 1-4 As shown, the sorting device includes a material conveying mechanism 100 , a sorting mechanism 200 , a material feeding mechanism 300 , a material returning mechanism 400 and a material receiving hopper 500 .

[0043] The material conveying mechanism 100 is used to convey materials.

[0044] Specifically, the feeding mechanism 100 may be a belt conveyor, preferably a synchronous belt conveyor.

[0045] The sorting mechanism 200 is arranged on the feeding mechanism 100 and has a plurality of material separation ports 201 . The sorting mechanism 200 can identify the type of materials on the feeding mechanism 100 and control different types of materials to enter different material separation ports 201 .

[0046] The discharge end of the feeding mechanism 300 is connected to the feed end of the feeding mechanism 100 for feeding materials into the feeding mechanism 100 .

[0047] Specifically, the feeding mechanism 300 may use a vibrating plate to feed the material into the feeding mechanism 100 in a fixed posture, so as to facilitate the sorting mechanism 200 to sort the material.

[0048] The material return mechanism 400 includes a material receiving component 410 located below multiple material distribution ports 201 and a classification storage module 420 connected to the material receiving component 410. The material receiving component 410 has multiple groups of material receiving ports 401. The material receiving component 410 can move so that each group of material receiving ports 401 can be connected to multiple material distribution ports 201 respectively. The classification storage module 420 has a storage device that is connected to each material receiving port 401 on the material receiving component 410 one by one. The material falling into the material receiving port 401 can be stored in the storage device connected thereto. The storage device has a discharge port 4201 that can be opened and closed. The material stored in the storage device can enter the feeding mechanism 300 through the discharge port 4201.

[0049] The receiving hopper 500 is located below the material distribution opening 201 and has a plurality of material discharge channels. The receiving hopper 500 can move so that the plurality of material discharge channels are connected to the plurality of material distribution openings 201 accordingly.

[0050] In an embodiment of the present invention, a material return mechanism 400 is set in the sorting device, and the material return mechanism 400 includes a material receiving component 410 located below the material distribution port 201 of the sorting mechanism 200 and a classification storage module 420 connected to the material receiving component 410. The material receiving component 410 has multiple groups of material receiving ports 401, and the material receiving component 410 can be moved so that each group of material receiving ports 401 can be respectively connected to the material distribution port 201 of the sorting mechanism 200. The classification storage module 420 has a storage device that is connected to each material receiving port 401 on the material receiving component 410 in a one-to-one manner. The material falling into the material receiving port 401 can be stored in the storage device connected thereto. The storage device has a discharge port 4201 that can be opened and closed, and the material stored in the storage device can enter the feeding mechanism 300 through the discharge port 4201. Through the coordination of multiple groups of receiving ports 401 and material distribution ports 201 on the receiving assembly 410, and the discharge of materials from the corresponding storage devices in the storage module, the sorting device has a simple structure and can sort materials multiple times in stages, thereby reducing the number of material sorting times, improving sorting efficiency, and effectively reducing sorting costs.

[0051] In one embodiment, if Figure 1-4As shown, the sorting mechanism 200 also includes a visual recognition module 220 and a separation component 210. The visual recognition module 220 and the separation component 210 are arranged in sequence along the material conveying direction of the feeding mechanism 100. The visual recognition module 220 is used to identify the type of material on the feeding mechanism 100. The separation component 210 includes a plurality of separators arranged in sequence along the material conveying direction of the feeding mechanism 100. The discharge port of each separator is connected to a plurality of material separation ports 201 in a one-to-one correspondence.

[0052] It can be understood that when the sorting mechanism 200 sorts the material transported on the feeding mechanism 100, the visual recognition module 220 first identifies the category of the material. When the identified material continues to be transported to the separation component 210, the separator corresponding to the material category in the separation component 210 is actuated to collect the material and discharge it from the discharge port of the separator into the corresponding separation port 201.

[0053] In a specific embodiment, Figure 1-5 As shown, the separator includes a switching cylinder 211, a blowing module 212 and an incoming material sensor 213. The feed port 2111 of the switching cylinder 211 and the blowing port of the blowing module 212 are relatively arranged on both sides of the material conveying direction of the feeding mechanism 100. The incoming material sensor 213 is arranged close to the blowing module 212. The incoming material sensor 213 is used to detect whether there is material on the feeding mechanism 100 between the blowing module 212 and the feed port 2111 of the switching cylinder 211.

[0054] Specifically, a downward-sloping feed channel is formed inside the adapter tube 211, the upper end opening of the feed channel forms a feed port 2111, and the lower end opening of the feed channel forms a discharge port. The incoming material sensor 213 can be a photoelectric sensor, an optical fiber sensor, or other types of sensors, as long as it can detect whether there is material on the feed mechanism 100 between the blowing module 212 and the feed port 2111 of the adapter tube 211, and is not limited here. The blowing module 212 blows the material on the feed mechanism 100 into the feed port 2111 of the adapter tube 211 through the air flow ejected from the blowing port, and then slides from the discharge port into the distribution port 201 through the downward-sloping feed channel. The blowing module 212 specifically includes a adapter block 2122 connected to the feed mechanism 100 and a blowing pipe 2121, a three-way valve 2123, and an air inlet connector 2124 fixed on the adapter block 2122. The air inlet connector 2124 is connected to the external air source through an air pipe.

[0055] It can be understood that the blowing module 212 in the separator can also be replaced by a cylinder 4232, an electric telescopic rod and other structures. In the technical solution of this embodiment, the blowing module 212 is used to blow the material into the adapter cylinder 211, which can reduce the friction and wear between the material and the feeding mechanism 100, and the blowing module 212 moves quickly and has high sorting efficiency.

[0056] In some embodiments, as Figure 1-4 As shown, the sorting device also includes a waste rejection mechanism 600, which is arranged on the feeding mechanism 100 between the visual recognition module 220 and the separation component 210. The waste rejection mechanism 600 is used to reject materials on the feeding mechanism 100 that cannot be identified by the visual recognition module 220 from the feeding mechanism 100.

[0057] Specifically, the waste removal mechanism 600 is similar to the above-mentioned separator structure. When the visual recognition module 220 of the sorting mechanism 200 detects that there are materials of an unrecognizable type (such as damaged or incomplete materials) on the feeding mechanism 100, these materials are removed by the waste removal mechanism 600 to prevent them from entering the subsequent separation component 210 and affecting the sorting of normal materials.

[0058] Of course, it is understandable that the waste rejection mechanism 600 can achieve waste rejection as long as it is set on the feeding mechanism 100 downstream of the visual recognition module 220, for example, it is set on the feeding mechanism 100 downstream of the separation component 210.

[0059] In one embodiment, if Figure 1-4 As shown, the material receiving assembly 410 includes a mounting plate 411 and a linear module 412 connected to the mounting plate 411 and used to control the movement of the mounting plate 411. Multiple material distribution ports 201 are arranged at intervals along the material conveying direction of the feeding mechanism 100, and multiple groups of material receiving ports 401 are arranged side by side on the mounting plate 411 along the material conveying direction of the feeding mechanism 100. The linear module 412 can drive the mounting plate 411 to move perpendicular to the material conveying direction of the feeding mechanism 100, so that each group of material receiving ports 401 can be respectively connected to multiple material distribution ports 201.

[0060] Specifically, the mounting plate 411 can be a rectangular plate, the length direction of which is along the material conveying direction of the feeding mechanism 100. This design can save space and enable each group of receiving ports 401 to be better connected with the corresponding material distribution port 201.

[0061] During the sorting process, the linear module 412 drives the mounting plate 411 to move perpendicularly to the material conveying direction of the feeding mechanism 100 , and controls different groups of material receiving ports 401 on the mounting plate 411 to communicate with the material distributing ports 201 accordingly.

[0062] In a specific embodiment, Figure 1-4 and Figure 6As shown, the storage includes a storage box 421, a sealing cover 422 and an opening cover assembly 423. A storage bin for storing materials is formed inside the storage box 421. The storage bin is connected to the material receiving port 401 through a feeding pipe (not shown in the figure). The storage bin is also connected to a negative pressure air source (not shown in the figure). The material falling into the material receiving port 401 enters the interior of the storage bin through the feeding pipe under the adsorption of the negative pressure air source. The opening cover assembly 423 is arranged on the storage box 421, and the sealing cover 422 is arranged on the opening cover assembly 423. A discharge port 4201 is provided on the storage box 421. The opening cover assembly 423 can control the sealing cover 422 to open and close the discharge port 4201.

[0063] It is understandable that the number of storages is not less than the number of all the receiving ports 401 on the mounting plate 411 , so that the materials falling into each receiving port 401 can be respectively stored in the storages connected to the receiving port 401 .

[0064] Specifically, the lid opening assembly 423 includes a mounting bracket 4231 fixed to the storage box 421 and a cylinder 4232 mounted on the mounting bracket 4231. One side of the sealing cover 422 is hingedly connected to the mounting bracket 4231. A connecting block 4221 is provided on the outer side of the sealing cover 422, and a connecting hole 4222 is provided in the connecting block 4221. The piston end of the cylinder 4232 is hingedly connected to the connecting block 4221 via a pin. The action of the cylinder 4232 controls the sealing cover 422 to open and close the discharge port 4201 on the storage box 421. After the sealing cover 422 closes the discharge port 4201, a negative pressure chamber is formed inside the storage bin under the action of the negative pressure gas source. The material falling into the receiving port 401 is sucked into the storage bin under the action of the negative pressure and stored. After the sealing cover 422 is opened, the negative pressure chamber is destroyed, and the material stored in the storage bin falls into the feeding mechanism 300 through the discharge port 4201.

[0065] In a more specific embodiment, Figure 1-4 As shown, the feeding mechanism 300 is a vibrating disk, the classification storage module 420 is arranged above the vibrating disk through the bracket 1000, the storage is arranged in a ring shape on the bracket 1000, and the bracket 1000 is also provided with a material guide plate 2000. The upper end of the material guide plate 2000 is located below the discharge port 4201, and the lower end of the material guide plate 2000 extends to the interior of the vibrating disk.

[0066] Specifically, the classification storage module 420 is set above the vibration plate through the bracket 1000. When the discharge port 4201 of the storage is opened, the materials stored in the storage bin can fall into the vibration plate under the action of gravity, and the upper and lower arrangement can also make full use of the space.

[0067] Since the vibrating plate is roughly circular, the storage reservoirs are arranged in a ring shape on the bracket 1000, which can be well adapted to the vibrating plate. It can be understood that the greater the number of storage reservoirs, the larger the diameter of the ring. To ensure that the material in each storage reservoir falls into the vibrating plate, a guide plate 2000 is also provided on the bracket 1000. The upper end of the guide plate 2000 is located below the discharge port 4201, and the lower end of the guide plate 2000 extends into the interior of the vibrating plate.

[0068] In a specific embodiment, Figure 1-4 As shown, the receiving hopper 500 is fixed on the mounting plate 411 , and the receiving hopper 500 can connect multiple material discharge channels with multiple material distribution ports 201 correspondingly under the drive of the linear module.

[0069] Specifically, the receiving hopper 500 is vertically arranged, tapering from its upper end to its lower end to facilitate the packaging of the material discharged from the receiving hopper 500. By securing the receiving hopper 500 to the mounting plate 411 of the receiving assembly 410 and utilizing the linear module 412 of the receiving assembly 410 to drive the movement of the receiving hopper 500, a separate drive device for the receiving hopper 500 is no longer required, simplifying the structure of the material dispensing device.

[0070] In some embodiments, as Figure 1-4 As shown, the sorting device also includes a supporting mechanism 700, which is arranged below the receiving hopper 500. The supporting assembly includes a cross-shaped linear module 710 and a supporting platform 720 arranged on the cross-shaped linear for placing the material box 800. The cross-shaped linear module 710 can drive the supporting platform 720 to move along the direction in which the feeding mechanism 100 conveys the material, and drive the supporting platform 720 to move perpendicular to the direction in which the feeding mechanism 100 conveys the material.

[0071] By setting up a carrying component, the material box 800 is placed on the carrying platform 720 of the carrying component, and the cross-shaped linear module 710 is used to drive the carrying platform 720 to move in the plane below the receiving hopper 500, thereby driving the material box 800 on the carrying platform 720 to move, so as to realize direct boxing of the material discharged from the receiving hopper 500.

[0072] In some specific embodiments, such as Figure 1-4As shown, the sorting device also includes a frame 900 and a controller (not shown in the figure). The feeding mechanism 100, the feeding mechanism 300, the return mechanism 400 and the supporting mechanism 700 are all arranged on the frame 900. The feeding mechanism 100, the sorting mechanism 200, the feeding mechanism 300, the return mechanism 400 and the supporting mechanism 700 are all electrically connected to the controller. By setting up the frame 900, the feeding mechanism 100, the feeding mechanism 300, the return mechanism 400 and the supporting mechanism 700 are all arranged on the frame 900, so that the entire sorting device becomes a whole, which is easy to move and install. The entire sorting mechanism 200 is controlled as a whole by setting up a controller (such as an industrial computer).

[0073] In summary, the working process of the sorting mechanism 200 is briefly described by taking chips as an example of the material to be sorted. The batch of chips is divided into six categories (corresponding to chip categories I-VI respectively), each category is divided into twelve groups (corresponding to chip groups 1-12 respectively), and each group is divided into eight groups (corresponding to chip groups AH respectively). In the sorting mechanism 200 of the sorting device, the separators of the separation component 210 are provided with twelve, and accordingly, there are also twelve material distribution ports 201. Among them, the material receiving component 410 of the return mechanism 400 has two groups of material receiving ports 401. The first group has six material receiving ports 401, which can be connected to six of the twelve material distribution ports 201 when the material receiving component 410 moves. The second group has twelve material receiving ports 401, which can be connected to the twelve material distribution ports 201 when the material receiving component 410 moves. The classification storage module 420 has a total of twenty memories, eighteen of which are connected to the eighteen receiving ports 401 on the receiving assembly 410. The receiving hopper 500 has a total of eight material discharge channels.

[0074] The sorting mechanism 200 is started, and the controller sets the sorting into six categories (corresponding to chip categories I-VI respectively). The linear module 412 of the return material mechanism 400 is controlled to move, so that the first group of receiving ports 401 on the mounting plate 411 moves to below the material distribution port 201, and the batch of chips is poured into the vibration plate. The chips are transported to the synchronous belt conveyor through the vibration plate. After identification and sorting by the sorting mechanism 200, the chips are sorted into six categories and stored in the six memories corresponding to the first group of receiving ports 401 of the receiving component 410. After this sorting is completed, the controller sets the next sorting to twelve large groups (corresponding to chip groups 1-12 respectively), controls the linear module 412 of the return material mechanism 400 to move, and moves the second group of receiving ports 401 on the mounting plate 411 to below the material distribution port 201, controls the memory storing Class I chips to open its unloading port 4201, pours Class I chips into the vibration plate, and transports Class I chips to the synchronous belt conveyor through the vibration plate. After identification and sorting by the sorting mechanism 200, the Class I chips are sorted into twelve large groups and stored respectively in the twelve memories corresponding to the second group of receiving ports 401 of the receiving component 410. After this sorting is completed, the controller sets the next sorting to eight groups (corresponding to chip groups AH respectively), controls the linear module 412 of the return mechanism 400 to move, moves the receiving hopper 500 to the bottom of the material distribution port 201, controls the memory storing the first large group of chips of Class I to open its discharge port 4201, pours the chips of the first large group of Class I into the vibration plate, and transports the chips of the first large group of Class I to the synchronous belt conveyor through the vibration plate. After identification and sorting by the sorting mechanism 200, the chips of the first large group of Class I are sorted into eight groups, and the eight groups of chips of the first large group of Class I are transported to the material box 800 on the carrying mechanism 700 for boxing through the discharge hopper. After sorting and boxing the chips of the first group of Class I, continue to sort and box the chips of the second group of Class I as above, until all twelve groups of Class I chips are sorted and boxed, then sort the Class II chips into twelve groups in turn, and sort and box the twelve groups of Class II chips in turn, and so on, until all six categories of chips are sorted and boxed.

[0075] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described.
