Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable sorting and processing technology, and in particular to a fruit and vegetable sorting device. Background Technology

[0002] After harvesting, fruits and vegetables need to be sorted according to requirements such as size, firmness, and maturity. Traditional belt-type sorting equipment can cause significant damage to the fruit and fruit bloom, and can only perform coarse sorting by size, which is inaccurate. Therefore, automatic fruit and vegetable sorting equipment has gradually emerged. For example, CN110355119A discloses an intelligent fruit and vegetable sorting equipment that automatically controls the uniform distribution of materials. It includes a feeding transmission device, a horizontal conveying device, and a pneumatic mechanism arranged sequentially on the machine frame. An industrial camera and an industrial control computer are arranged in conjunction with the horizontal conveying device. A multi-stage collision conveying device is set at the front end of the feeding transmission device to convey fruits and vegetables to the upward feeding plate. A fruit and vegetable posture guide frame is set above the rollers. An automatic pressing mechanism for stabilizing the horizontal conveyor belt is set on the machine frame.

[0003] Although the above solution can sort fruits and vegetables, it does not undergo coarse screening, which makes it easy for impurities to be present. Moreover, after being screened by the pneumatic mechanism, the fruits and vegetables still need to be sent to a manual re-sorting platform for further screening, so the degree of automation is relatively low. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a fruit and vegetable sorting device. The device first performs a coarse screening of the fruits and vegetables, then lays them flat, accelerates them, and feeds them into a high-speed guiding conveyor mechanism. This allows the fruits and vegetables to be transported and rotate at high speed, improving camera recognition efficiency. A spraying mechanism then sorts the fruits and vegetables based on the camera recognition results, spraying different categories of fruits and vegetables to their respective outlets, resulting in high sorting efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] An embodiment of the present invention provides a fruit and vegetable sorting device, including a fruit feeding mechanism, a uniform fruit sorting mechanism and a high-speed guiding conveyor mechanism arranged in sequence, wherein a camera recognition mechanism and a spraying mechanism are provided on the upper side of the high-speed guiding conveyor mechanism;

[0007] The uniform fruit-separating mechanism includes a filtering unit, a flat and uniform conveying unit, and an accelerated separation unit arranged in sequence; the high-speed guiding conveying mechanism includes multiple conveying chains, with several guide wheels symmetrically installed on both sides of the conveying chains; a guide wheel rotation unit is installed at one end of the conveying chain corresponding to the camera recognition mechanism, so that the guide wheel rotates during the camera recognition process; the blowing mechanism includes blowing units corresponding to the conveying chains, and the blowing units are used to blow the fruits and vegetables to the corresponding outlets according to the camera recognition results.

[0008] As a further implementation, the filtration unit is higher than the flat and uniform conveying unit, and a combing and dispersing mechanism is provided at the connection between the flat and uniform conveying unit and the filtration unit.

[0009] As a further implementation, the combing and dispersing mechanism includes a plurality of combing and dispersing components arranged sequentially along the transverse direction, with the combing and dispersing components arranged at an angle.

[0010] As a further implementation, the filtering unit includes a conveying medium with gaps;

[0011] The flat and uniform conveying unit includes a flexible conveyor belt, and a baffle is provided near the output end of the flexible conveyor belt.

[0012] As a further implementation, the acceleration separation unit is configured with single-stage acceleration or multi-stage acceleration. The acceleration separation unit includes a V-shaped conveying unit and a drive mechanism connected to the V-shaped conveying unit. The V-shaped conveying unit is driven by the drive mechanism.

[0013] The V-shaped conveyor unit includes multiple sets of V-shaped conveyor belts arranged side by side, with two V-shaped conveyor belts spaced apart in each set, and the V-shaped conveyor belts are inverted to cooperate with the drive shaft.

[0014] As a further implementation, the drive shaft is arranged at intervals along the length of the V-shaped conveyor belt to tension the V-shaped conveyor belt; the V-shaped conveyor belt and the drive shaft are engaged by a groove and a protrusion structure.

[0015] As a further implementation, a guide plate is provided on the upper side of the V-shaped conveyor belt; the guide plate is arranged in an inverted V shape and is spaced apart from each group of V-shaped conveyor belts.

[0016] As a further implementation, the guide wheels on both sides of the conveyor chain are connected to it by the same pin, and the guide wheels are provided with toothed parts facing the conveyor chain. The toothed parts are used to cooperate with the guide wheel rotation unit.

[0017] The guide wheel rotation unit includes a toothed belt that meshes with the toothed portion; the guide wheel surface has a V-groove.

[0018] As a further implementation, the blowing unit includes a mounting beam arranged along the transmission direction, and multiple blowing bodies are arranged along the length direction of the mounting beam;

[0019] The main body of the jetting device has multiple air outlets evenly distributed on one side, and the other side is connected to the air storage unit through an air pipe.

[0020] As a further implementation, the fruit feeding mechanism includes an inclined fruit feeding conveyor belt, and the surface of the fruit feeding conveyor belt is provided with a blocking part.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) The present invention includes a fruit feeding mechanism, a uniform fruit sorting mechanism, a high-speed guiding conveying mechanism and a sorting conveying mechanism arranged in sequence. The high-speed guiding conveying mechanism is equipped with a camera recognition mechanism and a spraying mechanism on its upper side. The camera takes pictures of the fruits and vegetables on the high-speed guiding conveying mechanism for recognition. After recognition, the corresponding signal is transmitted to the spraying mechanism. The spraying mechanism sprays and sorts the fruits and vegetables according to the camera recognition results, and sprays different categories of fruits and vegetables to the corresponding outlets. The various mechanisms work together to achieve efficient sorting of fruits and vegetables.

[0023] (2) The uniform fruit separation mechanism of the present invention includes a filter unit, a flat and uniform conveying unit and an accelerated separation unit arranged in sequence. First, the fruits and vegetables are roughly sorted to filter out impurities such as leaves and sand mixed in the fruits and vegetables. After the filtered fruits and vegetables are flat and separated, they are accelerated in front of the high-speed guiding conveying mechanism to make the separation more uniform.

[0024] (3) The flattening effect of the present invention is achieved by the height difference between the flattening and conveying unit and the filtering unit and the combing and dispersing mechanism. After flattening, the separation is accelerated by the V-shaped conveyor belt, so that the fruits and vegetables are arranged one by one on the conveyor belt; and the fruits and vegetables will not be side by side on the V-shaped conveyor belt, which ensures accurate photography.

[0025] (4) The main body of the high-speed guide conveying mechanism of the present invention is a chain drive. Guide wheels are symmetrically arranged on both sides of the conveying chain. Fruits and vegetables are stored and conveyed between the guide wheels. In addition to running together with the transmission chain, the guide wheels also rotate on their own. While the guide wheels rotate, they drive the fruits and vegetables to rotate. The number of rotations can be infinitely adjusted by adjusting the speed difference between the rotation power of the guide wheels and the toothed belt in the rotation unit of the guide wheels.

[0026] (5) The blowing mechanism of the present invention includes multiple blowing units, which can complete the efficient sorting of fruits and vegetables at different levels through multi-hole flexible linear blowing; the blowing mechanism occupies little space and can improve space utilization and sorting efficiency.

[0049] Example 1:

[0050] This embodiment provides a fruit and vegetable sorting device, such as... Figure 1 and Figure 2 As shown, it includes a fruit feeding mechanism 1, a uniform fruit dividing mechanism 2, a high-speed guiding conveyor mechanism 4, and a sorting conveyor mechanism 6 arranged in sequence. The high-speed guiding conveyor mechanism 4 is equipped with a camera recognition mechanism 3 and a blowing mechanism 5 on its upper side, and the camera recognition mechanism 3 is located close to the side where the uniform fruit dividing mechanism 2 is located.

[0051] Camera 27 takes pictures of the fruits and vegetables on the high-speed guide conveyor 4 from top to bottom for identification. After identification, the corresponding signal is transmitted to the blowing mechanism 5. The blowing mechanism 5 blows and sorts the fruits and vegetables according to the camera's identification results, blowing different categories of fruits and vegetables to the corresponding outlets. The sorted conveyor 6 is used to receive the sorted fruits and vegetables after blowing, facilitating the next production process.

[0052] Specifically, the fruit conveying mechanism 1 is used to transport the harvested fruits and vegetables to the uniform fruit distribution mechanism 2. One end of the fruit conveying mechanism 1 is higher than the other end of the uniform fruit distribution mechanism 2; that is, the fruit conveying mechanism 1 is inclined to form an inclined conveying mechanism. For example... Figure 3 As shown, the fruit feeding mechanism includes a fruit feeding conveyor belt 7 driven by a motor. The surface of the fruit feeding conveyor belt 7 is provided with blocking parts to prevent the fruits and vegetables from slipping during transportation.

[0053] The obstruction section of the fruit conveyor belt 7 can be achieved in the following ways: a belt with raised patterns or a modular mesh belt with baffles.

[0054] like Figure 4 As shown, the uniform fruit separation mechanism 2 includes a filtration unit 8, a flat and uniform conveying unit 9, and an accelerated separation unit 10 arranged in sequence. The filtration unit 8 is used to initially filter impurities such as leaves and sand mixed in the fruits and vegetables to achieve rough sorting; the flat and uniform conveying unit 9 is used to flatly separate the filtered fruits and vegetables; the accelerated separation unit 10 is used to accelerate the separation of the fruits and vegetables to make the separation more uniform. The accelerated separation unit 10 can be set to single-stage acceleration or multi-stage acceleration, depending on the type of fruits and vegetables.

[0055] like Figure 5 As shown, the filter unit 8 includes a conveying medium 11 with gaps, through which leaves and sand are allowed to pass through, achieving the purpose of filtration; an impurity conveying section is provided on the lower side of the conveying medium 11. In this embodiment, the conveying medium 11 can be a circular belt, chain, etc., and the impurity conveying section adopts the form of a common conveyor belt.

[0056] The evenly spreading and conveying unit 9 includes a flexible conveyor belt, which uses a soft material belt to evenly spread the fruits and vegetables, and the soft material protects the fruits and vegetables from bumps and knocks; for example... Figure 4 As shown, the flexible conveyor belt is equipped with a baffle 36 near the output end, which further ensures that the fruits and vegetables are evenly spread on the unit without being stacked.

[0057] like Figure 18 and Figure 19 As shown, the filtration unit 8 is higher than the flat and uniform conveying unit 9, and the height difference between the two is H. A combing and dispersing mechanism 37 is provided at the connection between the flat and uniform conveying unit 9 and the filtration unit 8. The flat and uniform effect is achieved by the height difference between the two stages and the combing and dispersing mechanism 37.

[0058] like Figure 19 and Figure 20 As shown, the combing and dispersing mechanism 37 includes a plurality of combing and dispersing components 38 arranged sequentially in the transverse direction (perpendicular to the conveying direction). The combing and dispersing components 38 are inclined, and the connection end of the combing and dispersing component 38 with the filter unit 8 is higher than the connection end with the flat and uniform conveying unit 9. The two sides of the combing and dispersing component 38 are inclined, and the combing and dispersing component 38 located in the middle is an isosceles trapezoid. The remaining combing and dispersing components 38 are symmetrically arranged on both sides of the combing and dispersing component 38, and the remaining combing and dispersing components 38 are parallelograms.

[0059] Each combing and dispersing component 38 is covered with a layer of soft material, which not only disperses the fruits and vegetables but also protects them from being bumped or knocked.

[0060] like Figure 6 As shown, the accelerated separation unit 10 includes a V-shaped conveyor unit and a drive mechanism. The V-shaped conveyor unit includes multiple sets of V-shaped conveyor belts 13, which are distributed laterally (perpendicular to the transmission direction), i.e., arranged side by side. Each set of V-shaped conveyor belts 13 is internally supported by a drive shaft 12, which is connected to the drive mechanism at one end. The drive mechanism includes a drive motor 15, which can be directly connected to the drive shaft 12 or connected to the drive shaft 12 through a transmission mechanism. The drive mechanism enables the V-shaped conveyor belts 13 to move synchronously.

[0061] Two V-shaped conveyor belts are set at 13 intervals in each group, such as... Figure 9 As shown, the V-shaped conveyor belt 13 is inverted, i.e., set in an inverted V shape, so as to cooperate with the drive shaft 12; a V-shaped receiving space is formed between the two V-shaped conveyor belts 13 for receiving fruits and vegetables. The V-shape ensures that the fruits and vegetables are arranged one by one on the accelerated separation unit 10 without stacking.

[0062] The V-shaped conveyor belt 13 is engaged with the drive shaft 12, such as Figure 8 As shown, the drive shaft 12 has a protrusion 16 around its circumference, and the V-shaped conveyor belt 13 has a groove 17 on the side facing the drive shaft 12. The groove 17 and the protrusion 16 are used to achieve the cooperation between the V-shaped conveyor belt 13 and the drive shaft 13.

[0063] In this embodiment, the protrusion 16 is arranged in a ring around the drive shaft 12, that is, the protrusion 16 is a ring structure that wraps around the drive shaft 12. The protrusion 16 corresponds one-to-one with the V-shaped conveyor belt 13, and the spacing between two adjacent protrusions 16 is set according to the V-shaped accommodating space.

[0064] like Figure 6 and Figure 7 As shown, a guide plate 14 is installed on the upper side of the V-shaped conveyor belt 13 via a crossbeam. The two ends of the crossbeam are fixed to the frame of the acceleration separation unit 10. The guide plate 14 is arranged at intervals with each group of V-shaped conveyor belts 13. The guide plate 14 is arranged in an inverted V shape, and there is a certain gap between adjacent guide plates 14. This gap corresponds to the upper side of the V-shaped receiving space and plays a guiding role for fruits and vegetables.

[0065] After being evenly spread by the sorting and dispersing mechanism 37, the fruits and vegetables are accelerated and separated by the V-shaped conveyor belt 13, arranging them one by one on the conveyor belt, ready to enter the next device. In this embodiment, the V-shaped conveyor belt 13 is equipped with two stages of accelerated separation, and more stages can be selected depending on the type of fruit and vegetable. When the fruits and vegetables are conveyed on the V-shaped conveyor belt 13, they will not be transported side-by-side; they will be transported one by one, effectively ensuring accurate subsequent photography.

[0066] The main body of the high-speed guide conveyor mechanism 4 is a chain drive, such as... Figure 10As shown, it includes multiple conveyor chains 19, each corresponding to a set of V-shaped conveyor belts 13. Sprockets 21 are installed at both ends of the conveyor chains 19, and the conveyor chains 19 move horizontally under the rotation of the sprockets 21.

[0067] like Figure 11 As shown, guide wheels 20 are installed on both sides of each conveyor chain 19. The guide wheels 20 are installed by pins 23 passing through the conveyor chain 19, forming a symmetrical arrangement relative to the conveyor chain 19. Each end of the pin 23 is connected to a guide wheel 20. The pin 23 can rotate relative to the conveyor chain 19, thereby enabling the guide wheels 20 to rotate.

[0068] The guide wheel 20 has V-shaped grooves on its surface, which are distributed on the outer circumference of the guide wheel 20. Fruits and vegetables are placed between adjacent guide wheels 20 and move together with the conveyor chain 19. One end of the guide wheel 20 facing the conveyor chain 19 is provided with a toothed part 22, which is arranged in a circle along the axial direction of the guide wheel 20. The toothed part 22 cooperates with the guide wheel rotation unit 18 to realize the rotation of the guide wheel 20.

[0069] like Figure 12 As shown, the guide wheel rotation unit 18 is located at one end of the conveyor chain 19 near the camera recognition mechanism 3, so as to realize the rotation of fruits and vegetables within the recognition range of the camera 27, ensuring no blind spots in the shooting. Figure 13 As shown, the guide wheel rotation unit 18 includes a toothed belt 24, a pulley 25, and a tensioning pulley 26. The toothed belt 24 is driven by the pulley 25 and tensioned by multiple tensioning pulleys 26. The toothed belt 24 is a conveyor belt with teeth on its surface. The teeth of the toothed belt 24 can mesh with the toothed portion 22. Through the meshing action, the guide wheel 20 rotates, which can prevent the guide wheel 20 from slipping during rotation.

[0070] In this embodiment, the fruits and vegetables are stored and transported between the guide wheels 20. In addition to running with the conveyor chain 16, the guide wheels 20 can rotate on their own. While rotating, the guide wheels 20 drive the fruits and vegetables on them to rotate. The number of rotations can be adjusted by adjusting the speed difference between the rotational power of the guide wheels 20 and the toothed belt 24.

[0071] like Figure 14 As shown, the camera recognition mechanism 3 includes a hardware and software control mechanism, a camera 27, and a light source 28. The camera 27 takes pictures of and recognizes fruits and vegetables under the action of the light source 28 and gives the results. At the same time, it transmits the fruits and vegetables to the blowing mechanism 5 for fruit and vegetable classification.

[0072] like Figure 15 and Figure 16As shown, the blowing mechanism 15 includes blowing units 29 corresponding to the conveyor chain 19. The blowing units 29 are used to blow fruits and vegetables to the corresponding outlets according to the camera recognition results. The blowing unit includes a mounting beam 33 arranged along the conveying direction, and multiple blowing bodies 31 are arranged along the length direction of the mounting beam 33 to blow the fruits and vegetables.

[0073] like Figure 17 As shown, the blower body 31 has a hollow interior, with multiple air outlets 35 on one side for blowing, and an air storage unit 34 located above the mounting beam 33 connected to the other side via an air pipe 32. The air storage unit 34 supplies air to each blower body 31. In this embodiment, the air storage unit 34 has a long strip structure to supply air to multiple blower bodies 31 simultaneously. Each blower body 31 has a receiving part 30 on its side, which receives the fruits and vegetables under the blowing action.

[0074] In this embodiment, the receiving part 30 is a flexible baffle that blocks the fruits and vegetables.

[0075] This embodiment achieves the connection between each process through the position setting of each mechanism. After the filtering unit achieves the coarse selection of fruits and vegetables, they are then uniformly divided and at least two-stage acceleration combined with the high-speed guide conveyor 4 so that the fruits and vegetables enter the recognition range of the camera 27 at high speed. Due to the rotation of the guide wheel 20, the fruits and vegetables can be photographed at high speed, improving the sorting efficiency. Moreover, the high-speed guide conveyor 4 can achieve stability in the rotation and linear transmission process of fruits and vegetables.

[0076] The blowing mechanism 5 has multiple channel outlets and can meet the blowing needs of fruits and vegetables of various sizes. At the same time, it can complete the efficient sorting of fruits and vegetables at different levels.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
