Description

Technical Field

[0001] This utility model relates to the field of fruit sorting technology, specifically a novel visual sorting machine. Background Technology

[0002] Fruits refer to plant fruits that are rich in nutrients such as vitamins, minerals, and fiber. They not only provide the human body with various nutrients, but also have the characteristics of being refreshing, thirst-quenching, and delicious, making them an important part of people's daily diet.

[0003] Traditional fruit sorting mainly relies on fruit sorting machines to separate fruits based on their diameter. While this method can sort fruits by size, it is difficult to sort them by quality. For example, some fruits may be of poor quality, with bruises, irregular shapes, insect infestations, or even partial damage and rot. Currently, most fruit sorting is done manually, which is time-consuming, labor-intensive, and reduces work efficiency. Therefore, there is an urgent need to design a new type of visual sorting machine to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of visual sorting machine, which aims to solve the problem that the sorting of fruits is mostly done manually, which is time-consuming, labor-intensive and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel visual sorting machine includes a frame on which a fruit conveying mechanism is mounted. A hopper is located above the fruit conveying mechanism at one end of the frame, and a finished product collection bin is fixedly connected to the fruit conveying mechanism at the other end of the frame. An equipment rack, a computer control panel, and a defective product collection bin are fixedly connected to the top of the frame along the direction from the hopper to the finished product collection bin. A camera facing the fruit conveying mechanism is fixedly connected to the top of the equipment rack. A pair of supplementary lights are fixedly connected to both sides of the camera on the equipment rack. An adjustment component is installed inside the fruit conveying mechanism corresponding to the equipment rack, used to adjust the position of the fruit being conveyed. The opening of the defective product collection bin faces the fruit conveying mechanism, and a defective product conveyor belt is installed at the bottom of the defective product collection bin.

[0007] Preferably, the fruit conveying mechanism includes a pair of main shaft sprockets rotatably connected to one end of the frame and a mounting bracket installed at the other end of the frame. A main shaft servo motor for driving the main shaft sprockets is installed on the frame. A pair of guide sprockets are rotatably connected to the bottom of the main shaft sprockets and to both ends of the mounting bracket. A conveyor belt is sleeved on the outer sides of the pair of main shaft sprockets and the three pairs of guide sprockets.

[0008] Preferably, the conveyor belt includes a pair of chains that mesh with a main shaft sprocket and a guide sprocket. A plurality of rotating shafts are rotatably connected between the pair of chains at equal intervals, and a plurality of rollers are fixedly sleeved on the outer side of the rotating shafts at equal intervals along the axial direction.

[0009] Preferably, the positioning assembly includes multiple synchronous pulleys rotatably connected to the frame, with a synchronous belt sleeved on the outer side of the multiple synchronous pulleys.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figures 1-2 This embodiment provides a novel visual sorting machine for sorting small, round fruits such as dates and walnuts. It includes a frame 1, on which a fruit conveying mechanism is mounted. A hopper 2 is located above the fruit conveying mechanism at one end of the frame 1, and a finished product collection bin 16 is fixedly connected to the fruit conveying mechanism at the other end of the frame 1. An equipment frame, a computer control panel 10, and a defective product collection bin 14 are fixedly connected to the top of the frame 1 along the direction from the hopper 2 to the finished product collection bin 16. A camera 8 facing the fruit conveying mechanism is fixedly connected to the top of the equipment frame. A pair of supplementary lights 9 are fixedly connected to both sides of the camera 8 on the equipment frame. The camera 8 and the supplementary lights 9 are electrically connected to the computer control panel 10. The internal components of the fruit conveying mechanism are correspondingly... An adjustment component is installed on the equipment frame to adjust the position of the fruit conveyor on the fruit conveyor mechanism. The opening of the defective collection bin 14 faces the fruit conveyor mechanism. A defective conveyor belt 15 is installed at the bottom of the inside of the defective collection bin 14. The fruit in the hopper 2 falls onto the fruit conveyor mechanism and is conveyed by the fruit conveyor mechanism. When the fruit is conveyed to the camera 8, the camera 8 takes a picture of the fruit. The computer analyzes the picture, and the supplementary light 9 provides supplementary lighting to the pictured fruit. When the analysis shows that the fruit is defective, the fruit is sent to the defective collection bin 14 and falls onto the defective conveyor belt 15 for collection. When the analysis shows that the fruit is qualified, the fruit is sent to the finished product collection bin 16 for collection, thus realizing the sorting of fruit quality.

[0020] In this embodiment, the fruit conveying mechanism includes a pair of main shaft sprockets 3 rotatably connected to one end of the frame 1 and a mounting bracket 5 installed at the other end of the frame 1. A main shaft servo motor 4 for driving the main shaft sprockets 3 is installed on the frame 1. The main shaft servo motor 4 is electrically connected to the computer control panel 10. A pair of guide sprockets 6 are rotatably connected to the bottom of the main shaft sprockets 3 and to both ends of the mounting bracket 5. A conveyor belt 7 is sleeved on the outer sides of the pair of main shaft sprockets 3 and the three pairs of guide sprockets 6. The conveyor belt 7 includes a pair of chains 701 connected end to end. The chains 701 mesh with the main shaft sprockets 3 and the guide sprockets 6. A plurality of rotating shafts 702 are rotatably connected at equal intervals between the pair of chains 701. The outer sides of the rotating shafts 702 are fixed at equal intervals along the axial direction. Several rollers 703 are connected. The fruit in the hopper 2 falls into the space between four adjacent rollers 703 and is limited. The main shaft servo motor 4 drives the main shaft sprocket 3 to rotate. With the assistance of three pairs of guide sprockets 6, the conveyor belt 7 is driven to rotate to transport the fruit. The conveying direction of the conveyor belt 7 is along the hopper 2 towards the finished product collection bin 16. Each guide sprocket 6 includes a sprocket and a shaft. The shaft is fixedly connected to the frame 1 and the mounting bracket 5. The sprocket and shaft are connected by a sprocket bearing instead of a hard fit, which achieves the special effect of the shaft not moving while the sprocket moves. This ensures that the chains on both sides of the small roller are evenly stressed during transmission and prevents the chains on both sides from being broken due to excessive stress caused by insufficient manufacturing precision.

[0021] In this embodiment, the bottom of the hopper 2 is inclined, and the mounting bracket 5 is also inclined, with the same inclination angle as the bottom of the hopper 2. This ensures that the conveyor belt 7 at the hopper 2 also has the same inclination angle as the bottom of the hopper 2. Compared to a flat hopper, the fruit's own weight allows for better spreading of the material without it piling up, facilitating efficient image capture during subsequent photography. The top of the mounting bracket 5 is rotatably connected to the frame 1, and the bottom of the mounting bracket 5 is connected to the frame 1 via length adjustment components such as adjusting screws. The hopper 2 and the mounting bracket 5 are fixedly connected by a support rod. By adjusting the length of the length adjustment components, the angle of the mounting bracket 5 can be adjusted, thereby adjusting the angle of the hopper 2. The inclination of the hopper 2 is adjustable rather than fixed, making it suitable for fruits of different sizes, diameters, and other characteristics, thus broadening the equipment's applicability.

[0022] In this embodiment, the positioning assembly includes multiple synchronous pulleys 11 rotatably connected to the frame 1. A synchronous belt 13 is commonly sleeved on the outer side of each synchronous pulley 11. A synchronous pulley servo motor 12, which drives one of the synchronous pulleys 11, is also mounted on the frame 1. The synchronous pulley servo motor 12 is electrically connected to the computer control panel 10. A gear 704 is fixedly sleeved on each shaft 702 corresponding to the synchronous belt 13. The gear 704 meshes with the synchronous belt 13. The synchronous belt 13 has a toothed outer side structure that meshes with the gear 704; this is prior art and will not be elaborated further. The multiple synchronous pulleys 11 guide the path of the synchronous belt 13, setting the top of the synchronous belt 13 parallel to the conveyor belt 7. The synchronous pulley servo motor 12 drives the connected synchronous pulley 11 to rotate, which in turn drives the synchronous belt 13 to rotate. The synchronous belt 13 drives the gear 704 to rotate, which in turn drives the rotating shaft 702 and the roller 703 on it to rotate. Through the contact friction between the roller 703 and the fruit, the fruit is rotated and its position is adjusted for taking pictures of the fruit from all angles. The computer control panel 10 is used to control the synchronous pulley servo motor 12. Depending on the diameter of the material, the camera 8 needs to accurately take pictures of the fruit from different angles during the conveying process. Adjusting the linear speed of the synchronous belt 13 can ensure that fruits of different sizes have the same rotational angular velocity, thereby taking qualified and accurate pictures.

[0023] In this embodiment, multiple sets of defective product collection bins 14 and defective product conveyor belts 15 are arranged between the computer control panel 10 and the finished product collection bin 16. One side of the defective product collection bin 14 is designed with an inclination, and the top of the defective product collection bin 14 is designed with an arc. Multiple sets of first air nozzles 19 corresponding to the positions of the defective product collection bins 14 are fixedly installed on the frame 1. Multiple sets of first air nozzles 19 are arranged inside the conveyor belt 7. Each set of first air nozzles 19 has multiple nozzles arranged along the length of the defective product collection bin 14. The air nozzles 19 are connected to the air supply equipment through a first air pipe. A first solenoid valve is installed on the first air pipe. The first solenoid valve is electrically connected to the computer control panel 10. When defective fruit is conveyed to the corresponding defective product collection bin 14, the first solenoid valve is controlled to activate the first solenoid valve. A solenoid valve opens, causing the nozzle 19 to blow air onto the substandard fruit, sending it into the substandard fruit collection bin 14. The substandard fruit moves along the inclined surface and rounded top of the collection bin 14, ensuring it falls accurately onto the substandard fruit conveyor belt 15 for collection and grading. In this embodiment, the nozzle 19 uses a dual-hole design, allowing the airflow to be sprayed in a strip shape, providing a larger contact area with the substandard fruit and ensuring more accurate removal of identified substandard fruit. Through multiple substandard fruit collection bins 14 and conveyor belts 15, substandard fruit can be divided into multiple grades. The upward blowing method maximizes space utilization, achieving a small footprint.

[0024] In this embodiment, a set of second jet nozzles is provided between a pair of main shaft sprockets 3. The second jet nozzles are mounted on the frame 1 and blow air towards the finished product collection bin 16. The second jet nozzles are connected to the air supply equipment through a second air pipe. A second solenoid valve is installed on the second air pipe. The second solenoid valve is electrically connected to the computer control panel 10 to control the opening of the second solenoid valve, so that the second jet nozzle blows the finished fruit into the finished product collection bin 16 for collection.

[0025] In this embodiment, a return conveyor belt 17 is installed on the frame 1 below the finished product collection bin 16. Unidentified fruits fall into the return conveyor belt 17 and are transferred by the external conveyor belt to the hopper 2 for re-sorting.

[0026] In this embodiment, an impurity conveyor belt 18 is provided between the mounting bracket 5 and the adjustment component. The impurity conveyor belt 18 is installed on the frame 1 and located inside the conveyor belt 7. A collection funnel is installed on the top of the impurity conveyor belt 18. The fruit moves and is conveyed on the conveyor belt 7, while the impurity conveyor belt 18 discharges small particles such as soil clods and sticks adhering to the fruit, so as to avoid contaminating the equipment and causing machine failure.

[0027] Working Principle: During operation, the main spindle servo motor 4 drives the main spindle sprocket 3 to rotate. With the assistance of three pairs of guide sprockets 6, the conveyor belt 7 rotates. The fruit in the hopper 2 falls between the rollers 703 on the conveyor belt 7 and is limited. The fruit moves and is conveyed on the conveyor belt 7. The impurity conveyor belt 18 discharges small particles such as soil and sticks adhering to the fruit. When the fruit is conveyed to the camera 8, the camera 8 takes a picture of the fruit. After the computer analyzes the picture, the supplementary light 9 provides supplementary lighting to the photographed fruit. At this time, the synchronous pulley servo motor 12 drives the connected synchronous pulley 11 to rotate, which in turn drives the synchronous belt 13 to rotate. The synchronous belt 13 drives the gear 704 at this location to rotate, which in turn drives the rotating shaft 702 and the rollers 703 on it to rotate. Through the contact friction between the rollers 703 and the fruit, the fruit is cleaned and transported. The fruit is rotated and repositioned to capture images from all angles. When a fruit is identified as defective, it is transported to the corresponding defective collection bin 14. At this point, the first solenoid valve is opened, causing the air nozzle 19 to blow air onto the defective fruit, which is then transported into the defective collection bin 14. The defective fruit moves along the inclined surface and the rounded top of the defective collection bin 14, ensuring it falls accurately onto the defective conveyor belt 15 for collection, thus ensuring the grading effect. When a fruit is identified as qualified, it is transported to the finished product collection bin 16. At this point, the second solenoid valve is opened, causing the second air nozzle to blow the finished product into the finished product collection bin 16 for collection. Unidentified fruit falls onto the return conveyor belt 17 and is then transferred by the external conveyor belt to the hopper 2 for re-sorting, thus achieving the sorting of fruit quality.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
