[0039] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0040] An automatic material sorting device for blister toothbrush heads includes a material bin 1, a material sorting centrifuge disk 2, a discharge chute 3, and a material sorting conveyor line 4.

[0041] The material bin 1 is used to cache materials and feed the materials into the material sorting centrifuge disk 2 according to production needs. Since the material sorting centrifuge disk 2 can arrange the disordered materials and control the discharge state of the materials, the material bin 1 has no requirements for the incoming material state. When replenishing materials, only the whole box of materials needs to be poured into the material bin 1. The materials referred to in the embodiments of the present invention are blister toothbrush heads.

[0042] The material sorting centrifuge disk 2 can control the discharge state of the materials through centrifugation and the internal structure setting, so that the materials enter the discharge chute 3 in an orderly manner and slide into the material sorting conveyor line 4 through the discharge chute 3.

[0043] Such as Figure 2 、 3As shown, the material sorting centrifuge disk 2 is fixed on the centrifuge disk frame 5. The material sorting centrifuge disk 2 includes a housing 201, an inner ring 202, and an outer ring 203. An annular platform extending along the circumference is provided on the inner side of the side wall of the housing 201, and this annular platform is the outer ring 203. The inner ring 202 is inclined and arranged inside the housing 201 and is located inside the outer ring 203. The highest side of the inner ring 202 is connected to the outer ring 203. A rotating motor is connected below the inner ring 202, and the rotating motor drives the inner ring 202 to rotate in an inclined posture. A discharge port 205 is also provided on the side wall of the housing 201. The inner side of the discharge port 205 is connected to the outer ring 203, and the outer side is connected to the discharge chute 3. A transparent and openable cover plate is installed on the top of the housing 201, and a feed port is provided on the cover plate for connecting to the silo 1.

[0044] The material entering the material sorting centrifuge disk 2 is located on the inner ring 202. After the inner ring 202 rotates ( Figure 3 shown as counterclockwise), under the action of centrifugal force, the material enters the outer ring 203 from the highest side of the inner ring 202. As the material continuously enters, the subsequent material pushes the previous material to move along the circumference on the outer ring 203. During the movement, the materials with inappropriate postures cannot be reliably supported by the outer ring 203 and will fall back to the lower inner ring 202 to repeat the above centrifugal material sorting process. When the material entering the outer ring 203 moves to the discharge port 205, it will be pushed by the subsequent material into the discharge chute 3 and slide down to the lower material sorting conveyor line 4.

[0045] Therefore, through the continuous rotation of the inner ring 202, the disordered materials can be sent out of the material sorting centrifuge disk 2 in a certain posture in an orderly manner and enter the material sorting conveyor line 4 through the discharge chute 3.

[0046] Furthermore, air nozzles 206 are provided on the inner wall of the housing 201 above the outer ring 203. The air nozzles 206 are used to cooperate with the rotation of the inner ring to blow the material to the outer ring 203.

[0047] Furthermore, a detection assembly 204 is also provided on the inner wall of the housing 201 for detecting whether there is material on the inner ring 202. The structure of the detection assembly 204 can refer to Figure 4 shown, including a detection rod 204-3 and a proximity switch 204-2. The detection rod 204-3 is rotatably suspended on the fixed block 204-1 and can swing left and right under the push of the material. The fixed block 204-1 is suspended on the housing 201 through a fixed rod 204-4. The structure of the detection rod 204-3 is as Figure 5As shown in the figure, it includes a rod body 204-31 for detecting materials. The upper end of the rod body 204-31 is connected to a rotating head 204-32. Above the rotating head 204-32, a detection head 204-33 for cooperating with a proximity switch 204-2 is provided. The rotating head 204-32 is rotatably connected inside the fixed block 204-1. The proximity switch 204-2 is installed on one side of the detection rod 204-3 and is located on the swinging path of the detection head 204-33. When there is a large amount of materials in the inner ring 202, the materials will hit the detection rod 204-3 every time they pass through the detection assembly 204, causing the detection rod 204-3 to shake. The proximity switch 204-2 is triggered by the detection head 204-33 to determine that there are materials and no feeding is required. When the materials are lower than the detection rod 204-3, the detection rod 204-3 will not shake, so the proximity switch 204-2 cannot obtain a signal, and it is determined that the material level in the inner ring is low and the silo needs to replenish materials for the material sorting centrifuge disc. Preferably, the detection assembly 204 is located above the lowest point of the inner ring 202.

[0048] As Figure 6 shown, the discharge chute 3 is supported on the centrifuge disc frame 5 by a chute bracket 6. The discharge chute 3 is composed of a first slide rail 301 and a second slide rail 302 on both sides, and an outward-expanded chute inlet 303 is provided at the upper end of the discharge chute 3. The lower ends of the first slide rail 301 and the second slide rail 302 are flush to form a discharge port for materials.

[0049] Preferably, the upper end of the first slide rail 301 is located outside the discharge port 205 of the material sorting centrifuge disc 2, and the upper end of the second slide rail 302 is located inside the discharge port 205 and blocks the outer ring 203. After the materials on the outer ring 203 move to this position, they cannot continue to move forward due to the blockage of the second slide rail 302, but enter the discharge chute 3 through the chute inlet 303.

[0050] As Figure 7 The material sorting conveyor line 4 includes a conveyor line frame 401 and a conveyor 402. The end of the conveyor 402 is connected to a rejection hopper 403. Unqualified products on the conveyor 402 will be sent by the conveyor 402 to the rejection hopper 403 and then fall into the collection device below through the rejection hopper 403.

[0051] The structure of the conveyor 4 is as Figure 8As shown, a belt conveyor is adopted, with a conveyor belt 404 arranged in the middle. A section of guardrail 410 is arranged on both sides of the conveyor belt 404. At the entrance of the conveyor 4, the guardrails 410 on both sides form an outward-expanding structure for docking with the outlet of the discharge chute 3 to facilitate the entry of products. The part of the conveyor 4 where the guardrail 410 is arranged is the main conveying area, and a transparent shield 408 that can be flipped open is also arranged in this area, through which the conveying situation of the internal products can be observed from the outside. Near the end of the conveyor 4, a positioning assembly 407 and a pressing assembly 409 are respectively arranged on both sides of the conveyor 4. The positioning assembly 407 can be used to fix the product 406 in a specific position to facilitate the use of a manipulator to pick up the product 406; the pressing assembly 409 is used to block the forward conveyance of other products after the product 406 when the product 406 cannot be picked up, so that, in cooperation with the conveyor belt 404, the unqualified product that cannot be picked up can be sent into the rejection hopper 403.

[0052] As Figure 9 , 10 As shown, the positioning assembly 407 includes a positioning cylinder 407-1, a connecting plate 407-2, a connecting block 407-3, and a rotating rod 407-4. The positioning cylinder 407-1 is fixed on the conveyor line frame 401 through a cylinder support, and the telescopic direction of the positioning cylinder 407-1 is perpendicular to the conveying direction of the conveyor. One end of the connecting plate 407-2 is connected to the cylinder rod of the positioning cylinder 407-1, and the other end is connected to the connecting block 407-3. The rotating rod 407-4 is installed on the connecting block 407-3, and the first rod body 407-5 of the rotating rod 407-4 extends towards the conveyor belt 404 and is perpendicular to the conveying direction. The rotating rod 404 includes an L-shaped rod body, including a vertical first rod body 407-5 and a second rod body 407-7. The first rod body 407-5 and the second rod body 407-7 are connected to both sides of a rotating shaft 407-6, and the rotating shaft 407-6 is rotatably installed on the connecting block 407-3. A groove 407-9 is arranged on the side of the second rod body 407-7 away from the first rod body 407-5. The end of the setscrew 407-8 installed on the connecting block 407-3 abuts against the groove 407-9, and a spring is sleeved on the setscrew 407-8. A groove capable of accommodating the second rod body 407-7 is arranged on the side surface of the connecting block 407-3, and a pressing block 407-10 is connected outside the groove opening to prevent the second rod body 407-7 from being ejected from the connecting block 407-3 by the spring.

[0053] The function of the rotating rod 407-4 is as follows: when the product reaches the positioning position at the front end, the positioning cylinder 407-1 extends, and the first rod body 407-5 of the rotating rod 407-4 blocks the product from moving forward, that is, it plays a positioning role; when the manipulator comes to pick up the product and needs to go back after picking up the product, the force of the conveyor belt 404 driving the product forward will drive the rotating rod 407-4 to rotate in the conveying direction (i.e., Figure 10 the clockwise direction in

[0054] ), compressing the spring, and the first rod body 407-5 makes way, so that the manipulator can pick up the product better. When there is a defective product, the positioning cylinder 407-1 retracts, making way for the defective product to flow into the rejection hopper 403 along the conveying line and flow out. Figure 11 The structure of the pressure component 409 is as

[0055] shown, including a pressure cylinder 409-1 and a pressure rod 409-2. The pressure rod 409-2 is fixed on a fixed plate, and the fixed plate is fixed on the cylinder rod of the pressure cylinder 409-1. The pressure cylinder 409-1 is fixed on the conveying line frame 401 through a cylinder bracket, and is arranged on both sides of the conveying direction of the conveyor with the positioning cylinder 407-1. The pressure rod 409-2 is perpendicular to the conveying direction, and the telescopic direction of the pressure cylinder 409-1 is perpendicular to the conveying direction.

[0056] The working process of the device of the present invention is as follows: after the product (blister toothbrush head) is poured into the hopper 1, the conveying line in the hopper 1 drives the product into the sorting centrifuge 2 and lands on the inner ring 202. The inner ring 202 drives the blister toothbrush head to rotate ( Figure 3 counterclockwise in ), and the centrifugal force of rotation makes the blister toothbrush head rotate outward to the outer ring 203. Due to the limited width of the outer ring 203, the blister toothbrush heads that are not in the right state and cannot stably land on the outer ring 203 will still fall on the inner ring 202, while the blister toothbrush heads in the right state are pushed by the subsequent blister toothbrush heads entering the outer ring 203 to move along the outer ring. When the blister toothbrush head reaches the discharge port 205 on the side of the sorting centrifuge 2, it will enter the discharge chute 3 and slide down into the sorting conveyor line 4; the conveyor belt 404 of the sorting conveyor line 4 drives the blister toothbrush head to be conveyed to the positioning point determined by the positioning component 407, that is, the first rod body 407-5 of the rotating rod 407-4 positions the blister toothbrush head, and then the manipulator picks up the positioned blister toothbrush head and transfers it to the next process. After the transfer, the next blister toothbrush head enters the positioning point, thus completing the sorting and pick-up feeding of the blister toothbrush head.

[0057] During this process, if the manipulator fails to pick up the blister toothbrush head, the blister toothbrush head needs to be removed to ensure the subsequent transportation and picking of the blister toothbrush head. At this time, the positioning cylinder 407-1 retracts, the rotating rod 407-4 leaves the conveyor belt 404, and the positioning of the first blister toothbrush head is released. The pressing rod 409-2 of the pressing cylinder assembly 409 extends to press the second waiting blister toothbrush head. Under the transportation of the conveyor belt 404, the unqualified first blister toothbrush head enters the rejection hopper 403 along with the conveyor belt 404 and is collected.

[0058] One side of the end of the conveyor belt 404 is also provided with a sensor 405, such as a photoelectric sensor, for detecting whether the blister toothbrush head reaches the positioning point. If it is detected that the blister toothbrush head has reached the positioning point, the manipulator performs the picking action.

[0059] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
