Description

Technical Field

[0001] This application relates to the field of fruit and vegetable sorting technology, and more particularly to fruit and vegetable rotary tables and fruit and vegetable sorting equipment. Background Technology

[0002] In the field of fruit and vegetable processing and sorting, rotary table systems are important automated equipment. In existing technologies, fruit and vegetable rotary tables typically employ fixed guide structures. During the high-speed rotation of the disc, fruits and vegetables are prone to radially disordered movement due to centrifugal force, resulting in excessive accumulation of fruits and vegetables on the outer ring and sparse distribution on the inner ring, affecting the sorting personnel's visibility and operational efficiency. Especially when handling fruits and vegetables of different sizes, traditional guide devices cannot be adaptively adjusted due to their fixed structure: for larger fruits and vegetables, the outer ring is easily obstructed by the guide structure during disc rotation, causing rolling interference; while for smaller fruits and vegetables, the insufficient guide path length prevents the inner ring from being effectively gathered. Therefore, existing fruit and vegetable rotary tables are difficult to adapt to fruits and vegetables of different sizes. Utility Model Content

[0003] One objective of this application is to provide a fruit and vegetable rotary table and a fruit and vegetable sorting device to solve the problem in the related art where the guide structure of the fruit and vegetable rotary table is fixed and it is difficult to flexibly adapt to fruits and vegetables of different sizes.

[0004] This application provides a fruit and vegetable rotary table, including:

[0005] A rotary bearing assembly includes a coaxially arranged disc and an annular baffle, wherein the disc is rotatably embedded inside the annular baffle and the disc is used to bear fruits and vegetables;

[0006] A guiding mechanism is installed on the inner side of the annular baffle and positioned above the disc. The guiding mechanism includes a guiding surface that extends from the inner wall of the annular baffle toward the center of the disc. The length of the guiding surface is adjustable relative to the center of the disc. The guiding surface is used to guide the fruits and vegetables toward the center of the disc when the disc rotates.

[0007] A drive mechanism is connected to the bottom of the disk and is used to drive the disk to rotate.

[0008] With the above structure and an adjustable guide surface, fruits and vegetables of different sizes can be actively guided to arrange neatly in the center area of ​​the disc under the centrifugal force generated by the rotation of the disc.

[0009] Optionally, the guiding mechanism includes:

[0010] The first guide member includes a first guide surface unit that extends and bends from the inner wall of the annular baffle towards the center, and the end of the first guide member is provided with a receiving cavity.

[0011] The second guide member is retractably partially housed in the receiving cavity. The second guide member includes a second guide surface unit, which is connected to the first guide surface unit to form the guide surface.

[0012] Through the above structure, the telescopic movement of the second guide member relative to the first guide member can easily change the effective length of the entire guide surface.

[0013] Optionally, the second guide member includes:

[0014] Support bar, which is connected to the first guide member;

[0015] A sleeve is movably fitted onto the support bar along the length direction of the support bar, and both the support bar and the sleeve are partially housed within the receiving cavity;

[0016] Fasteners that connect the support bar and the sleeve respectively, and the fasteners that can fix the sleeve at at least two positions along the sleeve's travel.

[0017] Through the above structure, the support bar provides structural rigidity, the sleeve slides along the support bar to achieve length changes, and the fasteners ensure that the sleeve can be firmly locked in the adjusted position.

[0018] Optionally, the annular baffle is provided with a feed inlet, the second guide member is disposed opposite to the feed inlet, and a gap is formed between the second guide member and the feed inlet, the gap being able to accommodate at least one fruit or vegetable, and the second guide member is used to limit and block the fruit or vegetable in the feeding direction of the feed inlet.

[0019] The above structure utilizes a second guiding component to achieve initial buffering and positioning of the fruits and vegetables entering the disc.

[0020] Optionally, the second guide member has a stop plane facing the feed inlet, and the first guide member has a stop arc surface on the side near the feed inlet. The stop plane and the stop arc surface are connected, and the stop arc surface is used to block fruits and vegetables that roll in the opposite direction to the rotation direction of the disc.

[0021] The above structure optimizes the control of fruit and vegetable movement in the feeding area, which can not only more effectively regulate the initial movement trajectory of fruits and vegetables, reduce chaotic rolling and accumulation, but also reduce damage to the fruit and vegetable skin through smooth transition.

[0022] Optionally, the disk includes:

[0023] The main body of the disc;

[0024] A leather substrate, wherein the leather substrate is disposed on the surface of the disk body;

[0025] A PVC surface layer is disposed on the surface of the leather substrate;

[0026] A silicone strip is circumferentially disposed along the edge of the main body of the disc, and the silicone strip forms an operating gap with the annular baffle. The silicone strip is used to restrict fruits and vegetables from contacting the annular baffle.

[0027] Through the above structure, the leather substrate provides cushioning and absorbs the impact of falling materials; the smooth and wear-resistant PVC surface layer reduces friction and facilitates the sliding and gathering of fruits and vegetables; the silicone strips on the edge serve as flexible buffer boundaries, which can prevent fruits and vegetables from being damaged by direct impact or friction against the rigid annular baffle, and can also maintain the gap required for the rotation of the disc.

[0028] Optionally, the slewing bearing assembly further includes a flexible protective strip, which is circumferentially disposed on the inner wall of the annular baffle. The flexible protective strip is used to absorb the impact force of fruits and vegetables when they are hit.

[0029] The aforementioned structure provides additional cushioning protection for fruits and vegetables that may be impacted at high speeds by the annular baffle. When the disc rotates at high speed or the fruits and vegetables bounce high and pass over the silicone strip at the edge of the disc, this flexible protective strip can absorb the impact energy, preventing the fruits and vegetables from being damaged by directly impacting the metal or hard inner wall of the annular baffle.

[0030] Optionally, the drive mechanism includes:

[0031] A connecting assembly, comprising a connecting shaft and a connecting plate, wherein the connecting shaft is perpendicularly connected to the connecting plate, the connecting plate is fixedly connected to the disk, and the connecting shaft is coaxially arranged with the disk;

[0032] A speed reducer, the output end of which is connected to the connecting shaft;

[0033] An electric motor, the motor shaft of which is connected to the input end of the reducer.

[0034] Through the above structure, the connecting components ensure that the driving torque is accurately and concentrically transmitted to the disc, avoiding eccentric vibration; the reducer converts the high speed and low torque of the motor into the low speed and high torque required for the disc to rotate, ensuring that the disc can rotate smoothly and powerfully when carrying fruits and vegetables; the motor provides a reliable power source.

[0035] Optionally, the fruit and vegetable turntable also includes a support frame, which includes three column units and a crossbeam structure. Each pair of adjacent column units are arranged in parallel and at equal intervals. Each column unit is vertically connected to the crossbeam structure. The top of each column unit is higher than the crossbeam structure. The top of each column unit is connected to the bottom of the annular baffle. The drive mechanism is mounted on the crossbeam structure.

[0036] Through the above structure, the three column units have good structural stability and evenly distribute the load-bearing weight; the crossbeam structure provides an installation position for the drive mechanism; the design of the raised support ring strip at the top of the column unit cleverly separates the rotating parts (disc and strip) from the drive unit in vertical space, reducing the risk of interference and facilitating installation and maintenance.

[0037] In another aspect, embodiments of this application also provide a fruit and vegetable sorting device, including a fruit and vegetable rotary table as described in any of the above claims.

[0038] The embodiments of this application can achieve the following technical effects: The fruit and vegetable rotary table provided by the embodiments of this application can better arrange fruits and vegetables spirally on the disc, which is convenient for operators or robotic arms to pick.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0049] This application provides a fruit and vegetable rotary table, which can be applied to fruit and vegetable processing equipment, fruit and vegetable sorting equipment, etc. For example, in this application embodiment, the fruit and vegetable rotary table is specifically applied to the manual packaging section of the fruit and vegetable sorting equipment. The fruit and vegetable rotary table arranges the sorted fruits and vegetables in a regular manner to facilitate the picking and packaging by operators or robotic arms. This application embodiment uses the design of a disc rotating counterclockwise as an example for illustration.

[0050] Please refer to the following: Figure 1 and Figure 2In some embodiments, the fruit and vegetable turntable 100 includes a rotating support assembly 10, a guiding mechanism 20, and a driving mechanism 30. The rotating support assembly 10 includes a coaxially arranged disc 12 and an annular baffle 11. The disc 12 is rotatably embedded inside the annular baffle 11 and is used to support fruits and vegetables. The guiding mechanism 20 is installed on the inner side of the annular baffle 11 and positioned above the disc 12. The guiding mechanism 20 includes a guiding surface 20a, which extends from the inner wall of the annular baffle 11 toward the center. The length of the guiding surface 20a is adjustable relative to the center of the disc 12. The guiding surface 20a is used to guide the fruits and vegetables toward the center of the disc 12 when the disc 12 rotates. The driving mechanism 30 is connected to the bottom of the disc 12 and is used to drive the disc 12 to rotate.

[0051] The structural principle of the fruit and vegetable turntable 100 in this embodiment is as follows: The turntable bearing assembly 10 includes a coaxially arranged disc 12 and an annular baffle 11. The disc 12 is rotatably embedded inside the annular baffle 11, forming a rotating platform for bearing fruits and vegetables. The annular baffle 11 acts as a barrier to prevent fruits and vegetables from being thrown out when the disc 12 rotates. A guide mechanism 20 is installed inside the annular baffle 11 and located above the disc 12. The guide surface 20a of the guide mechanism 20 extends and bends from the inner wall of the annular baffle 11 toward the center. The length of the guide surface 20a is adjustable to accommodate fruits and vegetables of different sizes and quantities. A drive mechanism 30 is connected to the bottom of the disc 12, providing support and driving the disc 12 to rotate.

[0052] As the disc 12 rotates, the fruits and vegetables, under the action of centrifugal force, move towards the edge of the disc 12 (i.e., towards the annular baffle 11). When the fruits and vegetables come into contact with the guide surface 20a of the guide mechanism 20, the guide surface 20a guides the fruits and vegetables to gradually converge towards the center area of ​​the disc 12 along its curved shape. By adjusting the length of the guide surface 20a, the length of the guide path of the fruits and vegetables on the guide surface 20a can be controlled to avoid the fruits and vegetables on the outer ring and thus adapt to different fruit and vegetable sizes.

[0053] Understandably, the fruit and vegetable rotary table 100 provided in this application embodiment can better arrange fruits and vegetables spirally on the disc 12, making it convenient for operators or robotic arms to pick them. At the same time, the length of the guide surface 20a can be flexibly adjusted to avoid the outer ring of fruits and vegetables being restricted from rotating with the disc 12 when the volume of the fruits and vegetables is large, and the inner ring of fruits and vegetables being irregularly arranged when the volume of the fruits and vegetables is small, thus flexibly adapting to fruits and vegetables of different sizes.

[0054] Please refer to the following: Figure 2 and Figure 3In some embodiments, the guiding mechanism 20 includes a first guiding member 21 and a second guiding member 22. The first guiding member 21 includes a first guiding surface unit 21a that extends and bends from the inner wall of the annular baffle 11 toward the center, and a receiving cavity is provided at the end of the first guiding member 21. The second guiding member 22 is retractably partially received in the receiving cavity, and the second guiding member 22 includes a second guiding surface unit 22a that connects with the first guiding surface unit 21a to form a guiding surface 20a.

[0055] Understandably, the guiding mechanism 20 adopts a split design, including a first guiding member 21 and a retractable second guiding member 22. The first guiding member 21 extends from the inner wall of the annular baffle 11 towards the center, with a receiving cavity at its end. The second guiding member 22 is inserted into this cavity through telescopic adjustment, and the two are connected to form a continuous guiding surface 20a. This structure achieves adjustment of the overall length of the guiding surface 20a through the telescopic movement of the second guiding member 22. For example, when handling larger fruits and vegetables, the second guiding member 22 can be retracted inward to shorten the effective range of the guiding surface 20a, preventing the outer fruits and vegetables from being squeezed due to the excessive length of the guiding surface 20a; conversely, when handling smaller fruits and vegetables, the guiding member extends outward to extend the guiding path and improve the gathering effect. This design breaks through the size adaptation limitations of traditional fixed guiding plates, and achieves adaptation to fruits and vegetables of different sizes through the physical extension of the mechanical structure.

[0056] In some embodiments, the connection between the second guide surface unit 22a and the first guide surface unit 21a means that the second guide surface unit 22a extends linearly along the tangential direction of the end of the first guide surface unit 21a, and there may or may not be a step difference between the second guide surface unit 22a and the first guide surface unit 21a. In other embodiments, the connection between the second guide surface unit 22a and the first guide surface unit 21a may also mean that the second guide surface unit 22a maintains the same curvature as the first guide surface unit 21a and extends outward from the end of the first guide surface unit 21a.

[0057] Please see Figure 4 In some embodiments, the second guide member 22 includes a support bar 221, a sleeve 222, and fasteners (not shown in the drawings). The support bar 221 is connected to the first guide member 21, and the sleeve 222 is movably fitted onto the support bar 221 along its length. Both the support bar 221 and the sleeve 222 are partially housed within a receiving cavity. The fasteners connect the support bar 221 and the sleeve 222 respectively, and the fasteners can fix the sleeve 222 at at least two positions along its travel.

[0058] Understandably, this embodiment of the application achieves the telescopic adjustment function of the second guide member 22 through the nested structure of the support bar 221 and the sleeve 222. The support bar 221, as a rigid frame, connects to the first guide member 21. The sleeve 222 slides along its axial direction to change the effective extension length of the second guide member 22, while fasteners fix the sleeve 222 in a preset position through mechanical locking methods such as screws or buckles. For example, when processing small fruits such as cherries, the sleeve 222 is fully pulled out to extend the guide surface 20a, allowing the fruits and vegetables to be gradually gathered along a longer path; while when sorting large fruits such as pomelos, the sleeve 222 is compressed to its shortest state to reduce the length of the guide surface 20a and avoid the accumulation of fruits and vegetables on the outer ring. This purely mechanical adjustment scheme ensures structural strength while achieving fine-tuning of the length through the cooperation of the sliding pair and the locking mechanism. The cooperation between the inner wall of the sleeve 222 and the support bar 221 further ensures a smooth transition of the guide surface 20a during the telescopic process, avoiding the risk of fruits and vegetables getting stuck.

[0059] In some embodiments, the support strip 221 is configured as a metal strip structure with a certain elastic deformation, the sleeve 222 is configured as a foam sleeve 222, and the fastener is a screw. The support strip 221 has a threaded hole, and the sleeve 222 has a plurality of through holes spaced apart in the length direction. Each through hole aligns with the threaded hole when the sleeve 222 slides relative to the support strip 221 to a corresponding position. The screw passes through the through hole and the threaded hole in sequence and is threadedly connected to the threaded hole to fix the sleeve 222. More easily understood, when the sleeve 222 slides to different positions, it can align with the threaded hole through the corresponding through hole at that position and be fastened by the screw to ensure the stability of the guide structure. In addition, when the fruits and vegetables rotate on the guide surface 20a, the foam properties of the sleeve 222 will absorb the impact of the fruits and vegetables, making them more gentle on the guide surface 20a, thereby reducing the impact of the inner ring fruits and vegetables on the outer ring fruits and vegetables when they come into contact with the outer ring fruits and vegetables.

[0060] Please refer to the following: Figures 1 to 3 In some embodiments, the annular baffle 11 is provided with a feed inlet 111, and the second guide member 22 is disposed opposite to the feed inlet 111. A gap is formed between the second guide member 22 and the feed inlet 111, and the gap is capable of accommodating at least one fruit or vegetable. The second guide member 22 is used to block the fruit or vegetable in the feeding direction of the feed inlet 111.

[0061] Understandably, in this embodiment, the second guide member 22 is arranged directly opposite the feed inlet 111, forming a buffer gap between them that can accommodate fruits and vegetables. When fruits and vegetables are fed into the feed inlet 111, the stop plane 22b of the second guide member 22 directly faces the fruits and vegetables, and the fruits and vegetables are initially positioned by the physical limitation of the gap. For example, when an apple enters, it impacts the stop plane 22b due to inertia, thereby dissipating the momentum in the feeding direction. Then, it rotates with the disc 12 until it is guided and gathered by the guide surface 20a, preventing the fruits and vegetables from sliding out directly or piling up disorderly.

[0062] In some embodiments, the support bar 221 is configured as a metal strip structure with a certain elastic deformation, and the sleeve 222 is configured as a foam sleeve 222. After the fruits and vegetables hit the support bar 221 and the sleeve 222, the momentum in the feeding direction can be effectively dissipated, while avoiding damage to the fruits and vegetables caused by the impact.

[0063] Please review Figure 3 In some embodiments, the second guide member 22 is provided with a stop plane 22b facing the feed inlet 111, and the first guide member 21 is provided with a stop arc surface 21b on the side near the feed inlet 111. The stop plane 22b and the stop arc surface 21b are connected. The stop arc surface 21b is used to block fruits and vegetables that roll in the opposite direction to the rotation direction of the disc 12.

[0064] Understandably, the stop plane 22b of the second guide member 22 connects with the stop arc surface 21b of the first guide member 21 to form a guide structure. When fruits and vegetables enter the disc 12 from the feed inlet 111, the stop plane 22b of the second guide member 22 directly bears the impact of the fruits and vegetables, quickly eliminating the horizontal momentum in the feeding direction by blocking, forcing the fruits and vegetables to move in the rotation direction of the disc 12. The stop arc surface 21b adopts an arc transition design, which can intercept fruits and vegetables that roll backward due to inertia or collision, and guide them back to the positive movement trajectory. The connection between the two allows the fruits and vegetables to complete the orientation correction in the early stage of feeding, avoiding accumulation or jamming caused by disordered rolling. At the same time, the smooth transition between the stop arc surface 21b and the stop plane 22b can reduce scratches on the skin of fruits and vegetables, especially protecting fragile fruits such as grapes and strawberries.

[0065] In some embodiments, the connection between the stop plane 22b and the stop arc surface 21b means that the stop plane 22b unit extends in a straight line along the end tangent direction of the stop arc surface 21b, and there may or may not be a step difference between the stop plane 22b and the stop arc surface 21b.

[0066] In some embodiments, the disc 12 includes a disc 12 body, a leather substrate, a PVC surface layer, and a silicone strip. The leather substrate is disposed on the surface of the disc 12 body, the PVC surface layer is disposed on the surface of the leather substrate, and the silicone strip is circumferentially disposed on the edge of the disc 12 body. The silicone strip forms an operating gap with the annular baffle 11, and the silicone strip is used to limit the contact of fruits and vegetables with the annular baffle 11.

[0067] Understandably, the disc 12 employs a multi-layered design. The leather backing serves as an intermediate buffer layer, absorbing the impact energy of falling fruits and vegetables and preventing internal damage caused by rigid collisions with the disc 12 body. The PVC surface layer uses food-grade PVC material, whose high smoothness reduces the coefficient of friction between the fruits and vegetables and the disc 12, making them easier to slide and gather under centrifugal force and less prone to friction with the fruits and vegetables. The silicone strip, through elastic deformation, forms an operating gap with the annular baffle 11, allowing the disc 12 to rotate freely while also mitigating the impact of the fruits and vegetables and preventing contact friction between the fruits and vegetables and the sidewalls of the annular baffle 11, thus preventing skin damage. This provides physical isolation and protection, especially for fruits and vegetables with fragile skins such as blueberries and cherries.

[0068] For example, the leather substrate can be replaced with a high-density silicone pad or polyurethane foam (PU) material to provide equivalent cushioning performance; the PVC surface layer can be replaced with a food-grade polytetrafluoroethylene (PTFE) coating to reduce the surface friction coefficient and improve abrasion resistance; the silicone strip can be replaced with a food-grade thermoplastic elastomer (TPE) bonded to the edge of the disc 12 by a molding process to extend service life while ensuring elasticity.

[0069] In some embodiments, the slewing bearing assembly 10 further includes a flexible protective strip, which is circumferentially disposed on the inner wall of the annular baffle 11. The flexible protective strip is used to absorb the impact force of fruits and vegetables when they are hit.

[0070] Understandably, in this embodiment, by setting a flexible protective strip, fruits and vegetables are prone to detaching from the silicone strip and impacting the annular baffle 11 when the rotation speed of the disc 12 is too high. The flexible protective strip on the inner wall of the annular baffle 11 absorbs the impact of the fruits and vegetables and prevents them from returning to the disc 12 and rotating with it. The flexible protective strip of the annular baffle 11 and the silicone strip of the disc 12 form a double impact protection for the fruits and vegetables, preventing them from being damaged by impacting the mechanical structure of the fruit and vegetable rotary table 100.

[0071] For example, the flexible protective strip can be made of structural components made of materials such as silicone, rubber or foam, without limitation.

[0072] Please refer to the following: Figure 1 , Figure 2 and Figure 5In some embodiments, the drive mechanism 30 includes a connecting assembly 31, a reducer 32, and a motor 33. The connecting assembly 31 includes a connecting shaft 311 and a connecting plate 312. The connecting shaft 311 is perpendicularly connected to the connecting plate 312, and the connecting plate 312 is fixedly connected to the disk 12. The connecting shaft 311 and the disk 12 are coaxially arranged. The output end of the reducer 32 is connected to the connecting shaft 311. The motor 33 shaft of the motor 33 is connected to the input end of the reducer 32.

[0073] Understandably, the drive mechanism 30 is rigidly connected to the connecting plate 312 coaxially via the connecting shaft 311, ensuring that the power transmission path is aligned with the rotation center of the disc 12, thus avoiding vibration or uneven speed caused by eccentricity. The reducer 32 matches the high speed of the motor 33 with the low speed and high torque required by the disc 12, allowing the disc 12 to maintain uniform rotation even when carrying fruits and vegetables. The fixed installation method of the connecting plate 312 and the disc 12 increases the contact area, disperses the shear stress during rotation, and prevents deformation or loosening of the connection due to long-term load. For example, the connecting plate 312 and the bottom of the disc 12 are connected by screws. Specifically, the bottom of the disc 12 has multiple threaded holes spaced around the axis, and the connecting plate 312 has multiple through holes, each through hole corresponding to a threaded hole. Each screw passes through the corresponding through hole and the corresponding threaded hole in sequence and is threadedly connected to the corresponding threaded hole.

[0074] In some embodiments, the connecting assembly 31 further includes a plurality of ribs 313, which are spaced apart around the axis of the connecting shaft 311. Each rib 313 is welded to the connecting plate 312 and the connecting shaft 311 respectively, thereby improving the overall structural stability of the connecting assembly 31.

[0075] In some embodiments, the fruit and vegetable turntable 100 further includes a support 40, which includes three column units 41 and a crossbeam structure 42. Each pair of adjacent column units 41 are arranged in parallel and at equal intervals. Each column unit 41 is vertically connected to the crossbeam structure 42. The top of the column unit 41 is higher than the crossbeam structure 42. The top of each column unit 41 is connected to the bottom of the annular baffle 11. The drive mechanism 30 is installed on the crossbeam structure 42.

[0076] Understandably, the bracket 40 adopts a triangular stabilizing structure of three column units 41 and a crossbeam. The columns are evenly distributed so that the load of the annular baffle 11 is evenly distributed to each support point, avoiding the risk of deformation caused by unilateral force. The crossbeam structure 42 not only bears the weight of the drive mechanism 30, but also, through the lifting design of the top of the columns, arranges the annular baffle 11 and the drive mechanism 30 in layers, reducing interference between rotating and fixed parts.

[0077] In some embodiments, the disk 12 can be supported on the beam structure 42 by the drive mechanism 30. In other embodiments, the annular baffle 11 is provided with an inner flange, on which a plurality of balls are provided. The edge of the disk 12 abuts against the balls to realize the rotation of the disk 12 relative to the annular baffle 11. The drive mechanism 30 only serves to drive the disk 12 to rotate.

[0078] In another aspect, this application provides a fruit and vegetable sorting device, including the fruit and vegetable rotary table 100 as described in the above embodiment.

[0079] It is understood that the fruit and vegetable sorting equipment in this application embodiment, by configuring the fruit and vegetable rotary table 100 of the above embodiment, allows the guiding mechanism 20 of the fruit and vegetable rotary table 100 to guide the fruits and vegetables to gradually and neatly arrange themselves inward on the disc 12, facilitating picking by operators or robotic arms.
