Description

Technical Field

[0001] The present invention relates to the field of agricultural technologies, particularly to the online detection of fruits, and specifically refers to a full-angle sorting fruit cup for image detection and a sorting method thereof. Background Art

[0002] The appearance of agricultural products is one of the main criteria for consumers to evaluate the quality of fruits. Part of agricultural waste is due to the low marketability of problematic products. Although the most important qualitative parameters of products are their nutritional value, physical properties, and uses, the primary basis for customers to screen products is the physical appearance and shape of the products. As a single-piece carrier device for fruits, the fruit cup is not only for the stable transportation of fruits, but also to display the quality information of fruits to external information collection devices as much as possible. As an important structure of the grading device, the working quality of the fruit cup directly affects the efficiency of the grading operation.

[0003] Currently, when performing single-piece transportation for different types of fruits, fruit cups with suitable shapes and characteristics are generally designed to complete the task, and they are fixedly installed on the transmission chain of the fruit sorter. For example, the Chinese invention patent with the authorization announcement number CN112934721A discloses a fruit sorting fruit cup; on the left and right sides of the rear side of the cup seat of this fruit cup, two flexible material stoppers for supporting fruits are symmetrically arranged. This improves the adhesion force of the fruit cup to the fruit. However, this kind of fruit cup and other existing fruit cups still have certain problems during the transmission and sorting processes. This kind of fruit cup and other existing fruit cups improve the adhesion force but lose the effect of making the fruits rotate when the double-cone roller sorting fruit cup transports the fruits. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a full-angle sorting fruit cup for image detection and a sorting method thereof, which not only avoids affecting the effect of making the fruits rotate by the double-cone roller, but also realizes dynamic weighing and enriches the sorting types.

[0005] The present invention is realized through the following technical solutions. A full-angle sorting fruit cup for image detection is provided, which includes a balance base installed on a conveying device, a multi-functional bracket rotatably arranged on the balance base, and a rotating roller mechanism installed on the multi-functional bracket;

[0006] The multi-functional bracket includes a guardrail that is closed along the circumference. On the upper parts of the front side wall and the rear side wall of the guardrail, horizontal axes extending away from the guardrail are respectively fixed, and the horizontal axis on the front side wall of the guardrail is coaxial with the horizontal axis on the rear side wall of the guardrail; on the left side wall and the right side wall of the guardrail, weighing plates extending along the horizontal direction are respectively fixed;

[0007] The balancing base is provided with two support frames extending to the front and rear sides of the guardrail respectively, and the support frames are provided with a slide groove adapted to the horizontal axis, and the length direction of the slide groove is consistent with the vertical direction;

[0008] The rotating roller mechanism includes a power roller and two supporting rollers arranged in the front-to-back direction. The left and right ends of the power roller and the two supporting rollers are rotatably connected to the left and right walls of the guardrail respectively. The power roller is located below the two supporting rollers and is transmission-connected to the two supporting rollers. The side walls of the guardrail and the two supporting rollers form a fruit placement groove. The roller surface of the power roller contacts the friction platform arranged below the sorting fruit cup and is transmitted through friction.

[0009] When the present solution is in use, the fruit sorting cup is mounted on the conveying device, a single fruit to be inspected is placed in the fruit placement slot, and the fruit is passed through the image detection device through the conveying device to detect the surface of the fruit; the reaction force of the friction platform on the fruit sorting cup causes the power roller to rotate, and the power roller drives the two supporting rollers to rotate, thereby causing the fruit to rotate, and the industrial camera performs full-angle image detection on the fruit; the load-bearing plate is supported on the weighing platform, and the slide slot is set so that when the weighing platform lifts the load-bearing plate, it can ensure that the multifunctional bracket moves upward and is separated from the support of the balance base, so that the weight of the multifunctional bracket and the fruit is fully applied to the weighing platform.

[0010] As an optimization, the support roller includes a cylindrical section and conical sections fixed at both ends of the cylindrical section, the middle of the power roller is cylindrical and matches the cylindrical section, and the two ends of the power roller are inverted cones and match the conical sections. The configuration of this optimization scheme increases the contact length between the power roller and the two support rollers, improves the reliability of the transmission, and thus ensures the rotation of the two support rollers.

[0011] As an optimization, the front end of the weighing plate is fixedly provided with an arc plate that bends and extends upward. This optimization scheme facilitates the movement of the load-bearing plate to the dynamic weighing table surface by providing the arc plate to avoid obstruction.

[0012] As an optimization, a compressed gas spray gun is provided on the discharge side of the sorting fruit cup, which is arranged toward the lower part of the multifunctional bracket. This optimization scheme utilizes the high-pressure gas sprayed by the compressed gas spray gun to rotate the multifunctional bracket around the horizontal axis to complete the overturning and unloading of the fruit. The structure is simple and it is convenient to control the spray pressure of the high-pressure gas to avoid excessive rotation of the multifunctional bracket, and ensure that after the spraying stops, the multifunctional bracket automatically rotates and resets under the action of gravity.

[0013] As an optimization, a supporting shoulder for supporting the multi-functional bracket is fixedly provided on the supporting frame, and the supporting shoulder is located on the side of the sliding groove away from the compressed gas spray gun. This optimization scheme supports the side of the multi-functional bracket away from the compressed gas spray gun through the setting of the supporting shoulder, avoiding the rotation of the multi-functional bracket in the direction away from the unloading side, and improving the stability during the process of conveying fruits.

[0014] As an optimization, the balance base includes a bottom plate fixedly connected to the lower ends of the two supporting frames, and two oppositely arranged fixing plates fixedly connected to the bottom surface of the bottom plate. A fixing notch adapted to the conveying chain is formed between the two fixing plates. This optimization scheme integrates the two supporting frames through the bottom plate, with a simple structure. The fixing notch formed by setting the fixing plates facilitates the connection with the conveying chain, realizing the conveying of the conveying chain.

[0015] As an optimization, balance shoulders extending away from the bottom plate in the left-right direction are fixedly connected to the left and right sides of the bottom plate respectively, and the balance shoulders on both sides are symmetrical to each other. This optimization scheme increases the extension distance on both the left and right sides of the bottom plate by setting the left-right symmetrical balance shoulders, improving the stability of the fruit cups.

[0016] As an optimization, the supporting frame includes a first frame body fixedly connected to the bottom plate and extending obliquely upward away from the unloading side, a second frame body extending vertically upward from the first frame body, a third frame body extending obliquely upward toward the unloading side from the upper end of the second frame body, and a fourth frame body extending vertically upward from the third frame body. The sliding groove is opened on the fourth frame body, and the first frame body, the second frame body, and the third frame body form a groove opening toward the unloading side. The supporting frame of this optimization scheme provides space for the setting of the friction platform by forming a groove, so that the power roller is supported on the friction platform. The structural setting of the supporting frame improves the stability of the fruit cups at the same time.

[0017] This solution also provides a sorting method using the above-mentioned sorting fruit cups, including the following steps:

[0018] 1. Install the sorting fruit cups on the conveying chain, place one fruit in the fruit placement groove of each sorting fruit cup, and drive the fruits forward under the drive of the conveying chain, and make the fruits pass under the industrial camera;

[0019] 2. During the process of conveying the fruits forward, the power roller moves along the lower friction platform, and the friction between the power roller and the friction platform causes the power roller to rotate. The power roller drives the two supporting rollers to rotate through friction transmission. The rotation of the supporting rollers causes the fruits to rotate, and the industrial camera is used to collect and detect the full-angle information of the rotating fruits;

[0020] 3. When the sorting fruit cup moves to the dynamic weighing platform, the weighing plate moves to the upper surface of the dynamic weighing platform. As the sorting fruit cup moves, the weighing platform lifts the bearing plate upward, causing the horizontal axis on the multi-functional bracket to move upward along the sliding groove, so that the multi-functional bracket is separated from the support of the balance base, and the dynamic weighing platform is used to weigh the multi-functional bracket and the fruit; when the sorting fruit cup moves to the separation of the weighing plate and the dynamic weighing platform, the multi-functional bracket falls and resets under its own weight.

[0021] 4. The fruits after weighing and grading are driven by the sorting fruit cup to move to the sorting position, and the fruits in the sorting fruit cup are unloaded at the corresponding positions according to different judgment results.

[0022] As an optimization, when unloading the fruits in the sorting fruit cup, high-pressure gas is sprayed by a compressed gas spray gun, and the lower part of the multi-functional bracket is pushed by the high-pressure gas, so that the upper end of the multi-functional bracket rotates towards the unloading side, and the fruits roll out from the multi-functional bracket.

[0023] The beneficial effects of the present invention are as follows:

[0024] By setting a sliding groove on the support frame, the multi-functional bracket and the support frame can move relatively up and down, thus realizing dynamic weighing and improving the weighing efficiency;

[0025] Through the interaction between the power roller and the friction platform, the power roller drives the support roller to rotate, and then drives the fruit to rotate, finally realizing the acquisition of all-round information of the fruit. Description of the Drawings

[0036] To clearly illustrate the technical features of this solution, the following describes this solution through specific implementation manners. In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0037] As Figure 1 shown, a full-angle sorting fruit cup for image detection includes a balancing base 3 installed on a conveying device, a multifunctional bracket 2 rotatably arranged on the balancing base, and a rotating roller mechanism 1 installed on the multifunctional bracket. Structures such as the rotating roller mechanism 1, the multifunctional bracket 2, and the balancing base 3 are connected and installed in sequence from top to bottom according to their respective functions. The balancing base is installed on the conveyor chain 8, and the sorting fruit cup is driven forward by the conveyor chain. Fruits are placed in the sorting fruit cup. An industrial camera 5 is provided above the moving trajectory of the sorting fruit cup to perform image detection on the surface of the fruits. A compressed gas spray gun 7 is provided on the discharging side of the sorting fruit cup and is arranged towards the lower part of the multifunctional bracket. The high-pressure gas ejected by the compressed gas spray gun is used to flip the multifunctional bracket to unload the fruits. A friction platform 6 is provided below the rotating roller mechanism to enable the rollers in the rotating roller mechanism to rotate.

[0038] The multi-functional bracket 2 that wraps the rotating roller mechanism 1 is installed together with the help of half-thread bolts, a chute 3a, and a balancing shoulder and a balancing base. In addition to providing wrapping and support for the rotating roller mechanism, the micro-gap guardrail of the multi-functional bracket 2 also plays a role in protecting the fruits being transported and preventing them from falling. The weighing plate designed as an integral structure with it can help the fruit cup complete the weighing operation of the fruits during the moving process, improving the grading efficiency of the fruits. Specifically, the multi-functional bracket includes a guardrail 2a that is closed circumferentially. The upper parts of the front side wall and the rear side wall of the guardrail are respectively fixed with horizontal axes extending away from the guardrail, and the horizontal axis on the front side wall of the guardrail is coaxial with the horizontal axis on the rear side wall, and the horizontal axis is perpendicular to the front side wall and the rear side wall of the guardrail. The guardrail serves as the outer frame of the two support rollers and the power roller, and the gaps between the two types of rollers and the guardrail are very small, which can avoid the occurrence of the phenomenon of fruit stalk jamming during the sorting process.

[0039] Weighing plates 2b extending horizontally are respectively fixed on the left side wall and the right side wall of the guardrail, and the weighing plate on the left side wall is flush with the weighing plate on the right side wall in the height direction. The front end of the weighing plate is fixed with an arc plate that bends upward to reduce the impact during the weighing process. A dynamic weighing platform 4 is provided on the moving trajectory of the weighing plate. The surface of the dynamic weighing platform is higher than the height of the weighing plate during the conveying process, and downward-sloping guiding plates are respectively provided at the front and rear edges of the dynamic weighing platform. When the fruit cup moves to the weighing position, the weighing plate moves along the guiding plate to the surface of the dynamic weighing platform, and the weights of the multi-functional bracket and the fruits are all borne by the weighing platform to achieve weighing, and then the weight of the fruits is calculated through calculation. As the fruit cup moves, the weighing plate moves down the weighing platform along the front guiding plate to complete the dynamic weighing.

[0040] A gas baffle opposite to the compressed gas spray gun and located below the horizontal axis is fixed at the lower part of the multi-functional bracket. The gas baffle and the guardrail are an integral part. The lower edges of the left side wall and the right side wall are respectively provided with the gas baffle, and both ends of the power roller are respectively installed on the gas baffles on both sides through bearings. The gas baffle not only provides an installation carrier for the power roller, but also blocks the high-pressure gas sprayed by the compressed gas spray gun, so that the multi-functional bracket rotates and tilts around the horizontal axis under the action of the high-pressure gas, causing the fruits to roll out of the multi-functional bracket to achieve flipping and unloading of the fruits.

[0041] The balance base 3 of the multi-functional bracket is supported by a half-thread bolt, a sliding groove 3a, and a supporting shoulder, mainly playing a supporting role. The asymmetrical distribution design of the sliding groove 3a and the supporting shoulder enables the multi-functional bracket to deflect in only one direction. The "S"-shaped support bracket with a special size and shape provides support force for the structures and devices above it, and its curved shape facilitates the contact between the power roller 1b and the external friction platform 6. In order to ensure that the fruit cup remains stable and does not tilt during movement, the symmetrically designed balance shoulders, like a balance pole, extend the lengths on both sides. Through the symmetric balance shoulders and the bottom slide rail support plate, the stability of the fruit cup movement is enhanced. The balance base 3 can be linked to the ear conveyor chain 8 through the fixed notch designed at its bottom, thereby realizing the movement of the fruit cup. Specifically, two support brackets 3c extending to the front and rear sides of the guardrail are provided on the balance base. A sliding groove 3a adapted to the horizontal axis is provided on the support bracket. The length direction of the sliding groove 3a is consistent with the vertical direction. By using the provided sliding groove, a vertical movement space is provided for the horizontal axis to ensure the realization of dynamic weighing. A supporting shoulder 3b for supporting the multi-functional bracket is fixedly provided on the support bracket. The supporting shoulder 3b is located on the side of the sliding groove 3a away from the compressed gas spray gun. The multi-functional bracket is supported by the supporting shoulder, improving the stability and preventing the multi-functional bracket from flipping in the reverse direction.

[0042] As an optimized solution, the balance base of this embodiment includes a bottom plate fixedly connected to the lower ends of the two support brackets, and two oppositely arranged fixing plates 3e fixedly connected to the bottom surface of the bottom plate. A fixing notch adapted to the conveyor chain is formed between the two fixing plates. The left and right sides of the bottom plate are respectively fixedly connected with balance shoulders 3d extending away from the bottom plate in the left-right direction, and the balance shoulders 3d on both sides are symmetrical to each other. By setting the balance shoulders, the left-right extension length of the balance base is increased, improving the stability. The support bracket includes a first frame body fixedly connected to the bottom plate and extending obliquely upward away from the unloading side, a second frame body extending vertically upward from the first frame body, a third frame body extending obliquely upward toward the unloading side from the upper end of the second frame body, and a fourth frame body extending vertically upward from the third frame body. The sliding groove is provided on the fourth frame body. The first frame body, the second frame body, and the third frame body form a groove opening toward the unloading side. By setting the groove, it is convenient to arrange the friction platform and avoid interference with the friction platform.

[0043] The rotating roller mechanism includes a power roller 1b and two support rollers 1a arranged in the front-rear direction. The left and right ends of the power roller and the two support rollers are respectively rotatably connected to the left side wall and the right side wall of the guardrail through micro bearings 2c. The power roller is located below the two support rollers and is in transmission connection with the two support rollers. The side walls of the guardrail and the two support rollers form a fruit placement groove for placing fruits to be detected. The roller surface of the power roller contacts a friction platform 6 arranged below the sorting fruit cup. Through the friction between the power roller and the friction platform, the power roller rotates, and the power roller is in close contact with the two support rollers. Specifically, the support roller includes a cylindrical section and conical sections respectively fixed at both ends of the cylindrical section. The middle part of the power roller is cylindrical and adapted to the cylindrical section, and the two ends of the power roller are inverted conical and adapted to the conical sections. By using the contact friction between the power roller and the two support rollers, the two support rollers are driven to rotate. When the support rollers rotate, the fruits are prompted to rotate to increase the surface detection area of the fruits. The industrial camera 5 responsible for external information collection performs full-angle information collection and detection on the rotating fruits.

[0044] The two support rollers 1a play a main supporting effect on the fruits. In order to reduce the damage caused by the fruit cup to the fruits during the grading and transportation process, the support rollers 1a are made of a relatively soft rubber material, which plays a role in buffering force. The power roller 2b is not only the power source for driving the fruits to rotate, but also can effectively avoid the phenomenon that smaller fruits fall.

[0045] A sorting method using the sorting fruit cup of this embodiment includes the following steps:

[0046] 1. Install the sorting fruit cup on the conveying chain. Place one fruit in the fruit placement groove of each sorting fruit cup. Driven by the conveying chain, the fruits are conveyed forward and pass under the industrial camera.

[0047] 2. During the process of conveying the fruits forward, the power roller moves along the friction platform below. By using the friction between the power roller and the friction platform, the power roller rotates. The power roller drives the two support rollers to rotate through friction transmission. The rotation of the support rollers makes the fruits rotate. The industrial camera is used to perform full-angle information collection and detection on the rotating fruits.

[0048] 3. When the sorting fruit cup moves to the dynamic weighing platform, the weighing plate moves to the upper surface of the dynamic weighing platform. As the sorting fruit cup moves, the weighing platform lifts the load-bearing plate upward, causing the horizontal axis on the multi-functional bracket to move upward along the chute, so that the multi-functional bracket is separated from the support of the balance base. The dynamic weighing platform is used to weigh the weight of the multi-functional bracket and the fruits. When the sorting fruit cup moves to the point where the weighing plate is separated from the dynamic weighing platform, the multi-functional bracket falls back to its original position under its own weight.

[0049] 4. After being weighed and graded, the fruits move to the sorting position driven by the sorting fruit cups, and the fruits in the sorting fruit cups are unloaded at the corresponding positions according to different judgment results. As an optimization scheme, when unloading the fruits in the sorting fruit cups, this method uses a compressed gas spray gun to spray high-pressure gas, which pushes the lower part of the multi-functional bracket through the high-pressure gas, causing the upper end of the multi-functional bracket to rotate towards the unloading side, and the fruits roll out from the multi-functional bracket.

[0050] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be realized by or adopted from the prior art, and will not be elaborated here; the above embodiments and drawings are only used to illustrate the technical solutions of the present invention and are not a limitation to the present invention.

Those of ordinary skill in the art should understand that any changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention do not depart from the purpose of the present invention and should also fall within the scope of the claims of the present invention.
