Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a visual sorting system for aquatic products. Background Technology

[0002] In the aquatic product processing sector, especially in shrimp processing, shrimp need to be graded and sorted according to indicators such as size, quality, and integrity to meet different market demands and increase product added value. Because shrimp have a slippery and sticky surface, they easily stick together and stack during transport, forming clumps or layers. This severely affects the detection accuracy of subsequent grading equipment (such as visual recognition systems), resulting in large sorting errors, low efficiency, and an inability to meet the needs of large-scale production.

[0003] Chinese patent literature discloses a shrimp processing machine's individualization and separation system, publication number CN111093377 B. This device is used for shrimp individualization and separation, dividing the shrimp layer into multiple rows, using a shaking disc to agitate and break up the shrimp clumps, and accelerating the separation and individualization of the shrimp through the water flow in the inclined trough. However, this type of system mainly focuses on dispersing shrimp from a clump into individual individuals, lacking the ability to accurately grade the individualized shrimp; at the same time, its separation process relies on the mechanical agitation of the shaking disc and the water flow guidance of the inclined trough, which has limited adaptability to shrimp of different sizes and varieties, and makes it difficult to achieve directional sorting and grading of shrimp based on detection results.

[0004] Therefore, in view of the shortcomings of existing aquatic product sorting equipment in terms of individualization effect, grading accuracy and processing efficiency, there is an urgent need for an aquatic product visual sorting system that can achieve efficient dispersion, identification and sorting of aquatic products in an integrated manner to meet the needs of modern aquatic product processing. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a visual sorting system for aquatic products that enables coordinated dispersion, identification, and sorting of aquatic products.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a visual sorting system for aquatic products, characterized in that it includes a storage hopper, a lifting conveying mechanism, a primary vibrating conveying mechanism, a sorting inclined plate, a secondary vibrating conveying mechanism, a speed-up conveying mechanism, a sorting conveying mechanism, a visual acquisition mechanism, a rejection mechanism, and a discharge conveying mechanism.

[0007] The height of the primary vibrating conveyor is higher than the height of the storage hopper. The input end of the lifting conveyor is connected to the storage hopper, and the output end of the lifting conveyor is connected to the primary vibrating conveyor.

[0008] The height of the secondary vibrating conveyor is lower than that of the primary vibrating conveyor; the material distribution ramp is inclined between the output end of the primary vibrating conveyor and the input end of the secondary vibrating conveyor; the material distribution ramp is provided with several material distribution components.

[0009] The speed-up conveying mechanism is located below the output end of the secondary vibrating conveying mechanism;

[0010] The input end of the sorting and conveying mechanism is connected to the output end of the speed-up conveying mechanism, and the conveying speed of the sorting and conveying mechanism is greater than the conveying speed of the speed-up conveying mechanism.

[0011] The visual acquisition mechanism is located above the upstream section of the sorting and conveying mechanism and is used to acquire images of the aquatic products transported by the sorting and conveying mechanism. In the downstream section of the sorting and conveying mechanism after passing the visual acquisition mechanism, multiple sets of rejection mechanisms and multiple sets of discharge conveying mechanisms are set. The discharge conveying mechanism is located below the conveying surface of the sorting and conveying mechanism, and the rejection mechanism is located above the conveying surface of the sorting and conveying mechanism. The rejection mechanism rejects the aquatic products transported by the sorting and conveying mechanism from the sorting and conveying mechanism and they fall onto the discharge conveying mechanism for output.

[0012] Furthermore, a material sorting section is provided upstream of the sorting and conveying mechanism. The material sorting section is located upstream of the visual acquisition mechanism. The material sorting section is formed by several material sorting sheets that are alternately distributed on both sides along the conveying direction of the sorting and conveying mechanism. The material sorting sheets act on the aquatic products conveyed by the sorting and conveying mechanism, causing the aquatic products to be conveyed in the center of the sorting and conveying mechanism.

[0013] Furthermore, the rejection mechanism includes photoelectric sensors and pneumatic nozzles installed on multiple conveying channels in the sorting and conveying mechanism; when the material passes through the photoelectric sensors and pneumatic nozzles, the pneumatic nozzles reject the material from the sorting and conveying mechanism and it falls into the discharge conveying mechanism.

[0014] Furthermore, the output end of the sorting and conveying mechanism is provided with a recycling conveying mechanism, which includes a transverse recycling conveying mechanism and a longitudinal recycling conveying mechanism; the transverse recycling conveying mechanism is perpendicular to the conveying direction of the sorting and conveying mechanism, and the longitudinal recycling conveying mechanism is arranged along the conveying direction of the sorting and conveying mechanism, and the material on the transverse recycling conveying mechanism can be transferred to the longitudinal recycling conveying mechanism.

[0015] Furthermore, one end of the discharge conveying mechanism extends to the longitudinal recycling conveying mechanism, and the material on the discharge conveying mechanism can be transferred to the longitudinal recycling conveying mechanism.

[0016] Furthermore, a vibration motor is installed at the bottom of the primary vibration conveying mechanism and the secondary vibration conveying mechanism, and a vibration spring is elastically supported at the bottom of both the primary vibration conveying mechanism and the secondary vibration conveying mechanism.

[0017] Furthermore, the secondary vibrating conveyor mechanism is divided into multiple material dropping chutes, the speed-up conveyor mechanism is divided into multiple acceleration channels, and the sorting conveyor mechanism is divided into multiple conveying channels. The material dropping chutes, acceleration channels, and conveying channels are arranged in a one-to-one correspondence.

[0018] Furthermore, the material handling sheets are arranged in the conveying channel, with the material handling sheets near the speed-up conveying mechanism arranged in an alternating pattern on both sides of the conveying channel, and the two material handling sheets near the vision acquisition mechanism in the conveying channel arranged symmetrically.

[0019] Furthermore, a discharge port is provided on one side of the conveying channel above the discharge conveying mechanism, and the material rejection mechanism pushes the material from the discharge port to the discharge conveying mechanism.

[0020] Furthermore, a material discharge baffle is provided between adjacent acceleration channels at the feed end of the speed-up conveying mechanism to distribute the falling material to the two acceleration channels.

[0021] In summary, this utility model has the following beneficial effects:

[0022] (1) The entire process of material separation from dispersion and conveying to precise sorting is automated by utilizing a primary vibrating conveyor, a sorting inclined plate, a secondary vibrating conveyor, a speed-up conveyor, a sorting conveyor, a vision acquisition mechanism, a rejection mechanism, and a discharge conveyor. The height difference between the primary vibrating conveyor and the storage hopper allows for drainage of aquatic products during transport, and the primary vibrating conveyor disperses the material through vibration, preventing material stacking or adhesion. The secondary vibrating conveyor, with its height difference from the primary mechanism, uses the sorting inclined plate to divide the material into several portions, further enhancing the sorting effect. The speed difference between the sorting conveyor and the speed-up conveyor separates the aquatic product slices, facilitating the vision acquisition mechanism's coordination with the rejection mechanism and the discharge conveyor for screening and grading according to specifications or set levels.

[0023] (2) The discharge conveying mechanism is set at intervals along the conveying direction. It can be graded according to the different qualities of the materials to meet the diverse sorting needs. A material handling section is set on the sorting conveying mechanism to transport the materials in the center. In addition, by setting up multiple discharge conveying mechanisms and corresponding identification and rejection mechanisms, the material position at the rejection mechanism is moved and then transferred to the corresponding discharge conveying mechanism to complete the screening and grading function. The identification and rejection are one-to-one, ensuring that materials of different grades are accurately pushed to the corresponding discharge port, thereby achieving accurate and efficient sorting.

[0024] (3) By adding a recycling conveyor, the recycling and sorting of materials can be realized. The transverse recycling conveyor belt and the longitudinal conveyor belt work together to send the unsorted or failed materials back to the starting point for reprocessing. The discharge conveyor belt extends to the longitudinal recycling conveyor belt so that the materials on the discharge conveyor belt can be transported to the longitudinal recycling conveyor belt for recycling.

[0035] The present invention will be further described in detail below with reference to the embodiments.

[0036] Example 1:

[0037] This embodiment provides a visual sorting system for aquatic products, including a storage hopper 1, a lifting conveyor 10, a primary vibrating conveyor 11, a material distribution inclined plate 12, a secondary vibrating conveyor 13, a speed-up conveyor 21, a sorting conveyor 22, a visual acquisition mechanism 4, a rejection mechanism 41, and a discharge conveyor 31. This visual sorting system for aquatic products, through the coordinated operation of multiple mechanisms, achieves automated processing of dispersed materials input from the starting point of the sorting system, sorting them within the conveying system.

[0038] The primary vibrating conveyor 11 receives material from the lifting conveyor 10 and disperses it through vibration before conveying it to the distribution inclined plate 12. A storage hopper 1 is installed outside the lifting conveyor 10, and the height of the primary vibrating conveyor 11 is higher than the height of the storage hopper 1. The input end of the lifting conveyor 10 is connected to the storage hopper 1, and the output end of the lifting conveyor 10 is connected to the primary vibrating conveyor 11. A conical baffle is installed on the primary vibrating conveyor 11. After the material is dispersed by the baffle, it is conveyed to the distribution inclined plate 12. The conical baffle can diffuse the material that enters the primary vibrating conveyor 11 in a concentrated manner, initially breaking up the agglomeration of the material and making the material more evenly distributed within the primary vibrating conveyor 11, thus preparing for further dispersion. The height of the primary vibrating conveyor 11 is higher than that of the storage hopper 1, so that the material is lifted and conveyed by the lifting conveyor 10 to the primary vibrating conveyor 11, which plays a role in draining water. This is especially useful for aquatic products that need to be thawed. The water on the aquatic products is drained out during the lifting and conveying process of the lifting conveyor 10 and falls back into the storage hopper 1, preventing excessive water from being carried out. The primary vibrating conveyor 11 disperses the material through vibration, preventing the material from piling up or clumping together.

[0039] The height of the secondary vibrating conveyor 13 is lower than that of the primary vibrating conveyor 11. A material distribution ramp 12 is inclined between the output end of the primary vibrating conveyor 11 and the input end of the secondary vibrating conveyor 13. Several material distribution components are provided on the material distribution ramp 12. The secondary vibrating conveyor 13 is lower than the primary vibrating conveyor 11. Utilizing the height difference, the material distribution ramp 12 distributes the aquatic products output from the primary vibrating conveyor 11, preventing clumping and improving the material distribution effect. The secondary vibrating conveyor 13 further enhances the material distribution effect. Thus, the dual vibration dispersion design makes the material dispersion effect more ideal.

[0040] The speed-up conveying mechanism 21 is positioned below the output end of the secondary vibrating conveying mechanism 13. The input end of the sorting conveying mechanism 22 is connected to the output end of the speed-up conveying mechanism 21, and the conveying speed of the sorting conveying mechanism 22 is greater than that of the speed-up conveying mechanism 21. By utilizing the speed difference between the speed-up conveying mechanism 21 and the sorting conveying mechanism 22, the distance between aquatic products is further increased, thereby further improving the separation effect.

[0041] The visual acquisition mechanism 4 is positioned above the upstream section of the sorting and conveying mechanism 22 to acquire images of the aquatic products transported by the sorting and conveying mechanism 22. Downstream of the sorting and conveying mechanism 22, past the visual acquisition mechanism 4, multiple sets of rejection mechanisms 41 and multiple sets of discharge conveying mechanisms 31 are installed. The discharge conveying mechanisms 31 are located below the conveying surface of the sorting and conveying mechanism 22, while the rejection mechanisms 41 are located above the conveying surface. The rejection mechanisms 41 remove the aquatic products transported by the sorting and conveying mechanism 22 from the sorting and conveying mechanism 22, allowing them to fall onto the discharge conveying mechanism 31 for output. The "primary vibration conveying mechanism 11, sorting inclined plate 12, secondary vibration conveying mechanism 13, speed-up conveying mechanism 21, and sorting and conveying mechanism 22" at the front end of the visual acquisition mechanism 4 all serve the visual acquisition mechanism 4, separating the aquatic products one by one. This facilitates image acquisition by the visual acquisition mechanism 4, allowing it to identify the specifications (size) of the aquatic products based on the acquired images, and also facilitating subsequent screening and grading according to set specifications.

[0042] Example 2:

[0043] This embodiment is based on a visual sorting system for aquatic products in Embodiment 1. In implementation, vibration motors are respectively installed at the bottom of the primary vibration conveying mechanism 11 and the secondary vibration conveying mechanism 13, and vibration springs are elastically supported at the bottom of both mechanisms. The vibration motors provide a stable vibration source for the primary and secondary vibration conveying, while the vibration springs buffer and adjust the vibration amplitude.

[0044] The secondary vibrating conveyor 13 is divided into multiple material drop chutes 14, the speed-up conveyor 21 is divided into multiple acceleration channels 24, and the sorting conveyor 22 is divided into multiple conveying channels 23. The material drop chutes 14, acceleration channels 24, and conveying channels 23 are arranged in a one-to-one correspondence. Vibration further disperses the adhered or stacked materials by dropping them in a dispersed state along the material drop chutes 14 into the acceleration channels 24 on the speed-up conveyor 21. The accelerated materials pass through the acceleration channels 24 and enter the conveying channels 23 of the sorting conveyor 22. Multiple conveying channels 23 can realize parallel processing of materials and increase the throughput per unit time.

[0045] In implementation, the material discharge chute 14 has a V-shaped cross-section. A material discharge baffle 17 is installed between adjacent acceleration channels 24 at the feed end of the speed-up conveying mechanism 21 to distribute the falling material to both sides of the acceleration channels 24. The V-shaped cross-section design utilizes the gravity of the material, guiding it to move along the center of the chute and preventing it from deviating within the chute. The material discharge baffle 17 effectively separates the different material discharge chutes 14, preventing material from veering off course at the feed end or failing to be guided into the acceleration channels 24. Several material distribution components on the material distribution ramp 12 can be selected from conical baffles to distribute the material.

[0046] A material sorting section is provided upstream of the sorting and conveying mechanism 22. This section is located upstream of the visual acquisition mechanism 4 and is formed by several material sorting plates 51 arranged alternately on both sides of the sorting and conveying mechanism 22 along its conveying direction. The material sorting plates 51 act on the aquatic products conveyed by the sorting and conveying mechanism 22, causing the aquatic products to be transported centrally on the mechanism. They also further separate the aquatic products. The material sorting plates 51 are located within the conveying channel 23. The material sorting plates 51 near the speed-up conveying mechanism 21 are arranged in a staggered pattern on both sides of the conveying channel 23, forming a channel that guides the material towards the center. Two material sorting plates 51 are symmetrically arranged within the conveying channel 23 near the visual acquisition mechanism 4. These two material sorting plates 51 further organize the material, ensuring it passes through in a single file, providing conditions for subsequent material identification.

[0047] In implementation, the rejection mechanism 41 includes photoelectric sensors 42 and pneumatic nozzles 43 installed on multiple conveying channels 23 in the sorting and conveying mechanism 22. When material passes through the photoelectric sensors 42 and the pneumatic nozzles 43, the pneumatic nozzles 43 reject the material from the sorting and conveying mechanism 22 and it falls into the discharge conveying mechanism 31. Multiple rejection mechanisms 41 are installed along the conveying direction on each conveying channel 23, and the photoelectric sensors 42 installed upstream of the pneumatic nozzles 43 detect and determine whether to reject the material. The material control system controls the pneumatic nozzles 43 to push the qualified material from the middle of the conveying channel 23 to one side according to the recognized signal. A discharge port 32 is provided on one side of the conveying channel 23 above the discharge conveying mechanism 31, and the rejection mechanism 41 pushes the material from the discharge port 32 into the discharge conveying mechanism 31. Multiple discharge conveyor mechanisms 31 are arranged at intervals along the conveying direction. The linkage between identification and pushing can be used to separate and transfer sorted materials according to different sorting levels, so as to facilitate subsequent packaging or processing processes.

[0048] Example 3:

[0049] This embodiment is based on a visual sorting system for aquatic products in the above embodiment. The output end of the sorting and conveying mechanism 22 is provided with a recycling and conveying mechanism 6. The recycling and conveying mechanism 6 includes a transverse recycling and conveying mechanism 61 and a longitudinal recycling and conveying mechanism 62. The transverse recycling and conveying mechanism 61 is perpendicular to the conveying direction of the sorting and conveying mechanism 22, and the longitudinal recycling and conveying mechanism 62 is arranged along the conveying direction of the sorting and conveying mechanism 22. The material on the transverse recycling and conveying mechanism 61 can be transferred to the longitudinal recycling and conveying mechanism 62.

[0050] One end of the discharge conveying mechanism 31 extends to the longitudinal recycling conveying mechanism 62, and the material on the discharge conveying mechanism 31 can be transferred to the longitudinal recycling conveying mechanism 62.

[0051] The recycling conveyor 6 forms a closed-loop sorting system, which includes returning unsorted, non-compliant, and left-on materials to the sorting starting point.

[0052] In the above embodiments, the lifting and conveying mechanism 10 can be designed with a chain plate type drain lifting conveyor belt. The chain plate surface is distributed with mesh holes, which can both carry materials and quickly filter out free water from the surface of the aquatic product slices. In implementation, each conveying mechanism is driven by a motor, and a water collection tank is set up in the draining area to collect water. A cable tray is set on one side of the aquatic product visual sorting system to facilitate the electrical wiring of each mechanism component. At the same time, an observation platform 7 with a certain height can be set on one side.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
