Description

Technical Field

[0001] The present application relates to the technical field of fruit sorting or processing, and in particular to a fruit posture adjustment system. Background Art

[0002] There is a strong demand for quality inspection and finished product packaging. In both cases, the fruit must be placed with the stem end facing upwards.

[0003] Fruit posture adjustment involves repositioning randomly placed fruit into a consistent position. Currently, this process often involves manual identification and alignment, which is labor-intensive, inefficient, and easily affected by fatigue, ambient light, and other factors during the identification and inspection process, resulting in poor accuracy.

[0004] Currently, the main methods for automatically adjusting the object posture are:

[0005] Image-based posture recognition method. Patent publication number CN211121091U discloses a fruit posture image acquisition device, comprising a frame, a robotic arm, and a placement base. The robotic arm includes a first swing arm, a second swing arm, a first stepper motor, a second stepper motor, and a camera. This patent allows for flexible acquisition of the complete three-dimensional shape of fruit.

[0006] This type of method requires the configuration of image acquisition and recognition equipment, as well as a special adjustment mechanism, and the system is complex and costly.

[0007] Chinese invention patent application publication number CN109174672A discloses a vibrating feeding device for intelligent fruit and vegetable sorting equipment, including a drive unit connected to a feeding plate. This patent is similar to patent application number CN210333407U, which discloses a multi-stage collision-assisted fruit and vegetable posture correction feeding device. The device includes a frame with a conveyor belt roller and a roller cover. Fresh fruit is easily damaged by collision and vibration, making this method unsuitable for posture correction of fresh fruit. Summary of the Invention

[0013] Furthermore, the fruit posture adjustment system also includes: a loading device for conveying the fruit to a loading area of the transport device.

[0014] Furthermore, relative to the transport route of the transport device, the loading area of the loading device is arranged between the selecting device and the adjusting device.

[0015] Furthermore, relative to the transport route of the transport device, the lifting device is arranged between the loading area of the loading device and the adjusting device.

[0018] On the other hand, the aforementioned fruit posture adjustment system is used to adjust the posture of pomelo fruit so that the tip of the pomelo fruit faces upward.

[0046] It should be noted that the modifications of "one" and "multiple" mentioned in this application are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0047] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] like Figure 1 As shown, the fruit posture adjustment system of the present application includes: an identification device 20, a selection device 30, a lifting device 40, an adjustment device 50, a transportation device 60 and a loading device.

[0049] Among them, the recognition device 20 is used to identify the posture of the fruit; the selection device 30 is used to select the fruit whose posture meets the requirements; the lifting device 40 is used to raise the fruit to a preset height; these three parts are technical solutions well known to those skilled in the art and will not be elaborated here.

[0050] The adjusting device 50 is used to adjust the posture of the fruit falling from the lifting device 40; the transporting device 60 is used to transport the fruit to the lifting device 40 and transport the fruit that is not selected by the selecting device 30 at the identification device 20 to the adjusting device 50. The loading device is used to transport the fruit to the loading area of the transporting device 60, such as Figure 1 As shown, relative to the transport route of the transport device 60 , the loading area of the loading device is arranged between the selecting device 30 and the adjusting device 50 .

[0051] As a specific embodiment, the adjustment device 50 includes at least one posture adjustment device 50. Furthermore, the damping effect of the damping device is applied to the fruit in the fruit drop channel by a damping medium driven by the damping device. The ratio of the length of the transport route formed by the transport device and the lifting device to the length of the fruit drop channel ranges from 25 to 35, preferably from 30 to 35, and preferably 29.57. The ratio of the linear velocity of the transport device to the length of the fruit drop channel ranges from 0.3 to 0.5, preferably from 0.35 to 0.45, and preferably 0.4.

[0052] The whole system can adjust the posture of the pomelo fruit so that the tip (fruit stem end) of the pomelo fruit faces upward.

[0053] like Figures 2 to 5 As shown, the posture adjustment device 200 of this embodiment includes a channel device 201. The channel device 201 provides at least one fruit falling channel 201a for fruits to pass through when falling.

[0054] In order to allow the damping medium to enter the fruit falling channel 201a and apply a damping effect to the fruit, the channel device 201 is also provided with a plurality of layered medium channels 201b. These medium channels 201b are used to allow the damping medium to enter the channel device 201 and apply a damping effect to the fruit in the fruit falling channel 201a so that the fruit can change its falling posture under the damping effect when falling from the channel device 201.

[0055] As a specific solution, the damping medium contained within medium channel 201b is liquid and / or gas. Generally, a single medium can be used, but a mixed or alternating combination of liquid and gas can also be used to provide damping. Mixed refers to a single medium channel 201b simultaneously outputting a mixture of liquid and gas, such as a mixture of water and air. Using only water can damage the fruit's appearance, while using only gas may not provide sufficient damping. Alternating methods include temporal and positional alternation. Specifically, during a certain period, medium channel 201b outputs liquid into fruit-dropping channel 201a, while during another period, gas is output. This pulsed alternation allows for better fruit posture adjustment. However, this approach places high demands on the equipment driving the medium and valves in the pipelines, and can be prone to damage. As another alternative, different medium channels 201b can output different media, such as water and air, at the same time. As a specific solution, media channels 201b at the same height, or media channels 201b on the same level (possibly with a small height difference), can output the same type of medium, such as liquid. Then, media channels 201b on another level can output a different type of medium, such as gas. This way, at different stages of the fruit's fall, the fruit will experience damping from the same medium. Throughout the entire falling process, the alternating effects of different damping media combine the advantages of both gas and liquid, effectively damping the fruit.

[0056] As a specific solution, the extension direction of medium channel 201b is configured to obliquely intersect with the falling direction provided by fruit-dropping channel 201a, and the extension direction of medium channel 201b is configured to converge toward the center of fruit-dropping channel 201a. With this solution, the extension direction of medium channel 201b determines the direction in which the damping medium is output to fruit-dropping channel 201a. The upwardly inclined medium channel 201b causes the output damping medium to exert at least two forces on the fruit: an upward force and a force toward the center. This not only prevents the fruit from falling too quickly, but also creates a tendency for the fruit to roll (though rolling is not guaranteed). As a result, the fruit is decelerated by the damping medium as it falls, and the forces exerted by the damping medium in all directions correct its falling posture, ultimately adjusting to a position with the stem end facing upward.

[0057] As a preferred solution, the angle β formed by the extension direction of the medium channel 201b and the falling direction provided by the channel space ranges from 40° to 60°, preferably from 40° to 50°, and preferably 45°. This angle selection can better achieve the posture adjustment effect.

[0058] As a specific solution, the technical concept of the present application can be realized by connecting a corresponding conduit to the outside of a cylindrical structure, but the overall assembly and production of the equipment are not easy to achieve.

[0059] As a preferred embodiment, the channel device 201 is configured to integrally form a fruit drop channel 201a and a medium channel 201b. The channel device 201 also has an interlayer space 201c to connect the different medium channels 201b. This has the advantage that the medium channels 201b of the channel device 201 do not need to be connected to many external pipes, and the overall structure can withstand high pressure.

[0060] In order to ensure that the damping medium can act on the fruits more evenly when it is emitted into the fruit falling channel 201a, the cross-sectional shape of the medium channel 201b includes at least one curved edge, especially an arc edge.

[0061] As a further preferred embodiment, the channel shape of medium channel 201b is configured as a runway. This channel shape can extend to the final outlet of medium channel 201b or can be the shape of any or all cross-sections of medium channel 201b. The runway shape avoids the high probability of cutting the fruit caused by the medium flow generated by cross-sectional shapes with narrow or sharp corners (such as long rectangles), while the use of a circular cross-section would result in a limited damping area. The runway shape ensures a sufficient area without causing a noticeable cutting effect. Furthermore, combined with the distribution of medium channel 201b, it can achieve a better damping effect.

[0062] As a further preferred solution, to allow the fruit to adjust its posture during the falling process while preventing the channel device 201 from being too high (the fruit falling channel 201a from being too long), which would otherwise cause excessive gravitational acceleration of the fruit, the ratio of the distance L4 between the two medium channels 201b in the falling direction to the length L3 of the fruit falling channel 201a is in the range of 0.15 to 0.25, preferably in the range of 0.18 to 0.22, with a preferred value of 0.2.

[0063] In order to ensure the flow rate of the damping medium and at the same time ensure the structural strength of the channel device 201, the fruit falling channel 201a is constructed as a rotating body space with the central axis 201d as the axis, and the ratio of the arc γ occupied by the medium channel 201b in the circumferential direction to the arc θ between the two medium channels 201b is in the range of 0.3 to 0.4, preferably in the range of 0.35 to 0.38, and the preferred value is 0.375.

[0064] The distance L4 between the medium channels 201b in the falling direction ranges from 90 mm to 120 mm, preferably ranges from 95 mm to 115 mm, and preferably is 100 mm.

[0065] The arc spacing θ of the medium channel 201b in the circumferential direction ranges from 60° to 80°, preferably from 70° to 75°, and preferably is 72°.

[0066] The cross-sectional area of the medium channel 201b is in the range of 400 cm 3 Up to 600cm 3 , the preferred range is 500cm 3 Up to 550cm 3 , the preferred value is 531cm 3 .

[0067] The benefit of ensuring the above-mentioned dimensional design is also to ensure that the damping medium generates a damping arc range in the circumferential direction.

[0068] like Figures 6 to 9 As shown, a posture adjustment device 100 as another embodiment includes: a channel device 101 and a damping flexible finger 102.

[0069] The channel device 101 forms at least one fruit-dropping channel 101a through which fruit passes as it falls. Several damping flexible fingers 102 are configured to apply damping to the fruit in the fruit-dropping channel 101a by contact, thereby adjusting the fruit into a specific posture, at least by tumbling, as it falls through the channel device 101. For example, a fruit such as a grapefruit can be adjusted from a random posture to a point-upward position as it falls to the bottom. This adjustment is achieved by the principle that the fruit's own damping feedback varies, allowing it to fall with its center of gravity as the stable posture.

[0070] As a more specific solution, the channel device 101 is constructed as a channel tube, the inner wall of which forms a fruit falling channel 101a. A plurality of damping flexible fingers 102 are at least partially made of elastic material and fixedly mounted to the channel tube. Figures 1 to 4 As shown, the damping flexible fingers 102 are at least partially disposed in the fruit falling channel 101 a and at least two damping flexible fingers 102 are disposed at different positions and / or have different extension directions.

[0071] Specifically, the plurality of damping flexible fingers 102 are dispersedly disposed at different positions of the fruit falling channel 101 a in the falling direction so that the fruits are subjected to differential falling damping effects when falling in the fruit falling channel 101 a .

[0072] Specifically, the ratio of the distance L1 between the two damping flexible fingers 102 in the falling direction to the length L2 of the fruit falling channel 101a in the falling direction is in the range of 0.17 to 0.25, more preferably in the range of 0.2 to 0.24, and preferably 0.235. This ratio design ensures that the density of the damping flexible fingers 102 is sufficient to adjust the fruit posture.

[0073] Specifically, the plurality of damping flexible fingers 102 are dispersedly disposed at different positions in the circumferential direction of the fruit falling channel 101 a so that the fruit is subjected to differentiated damping effects around the periphery when falling in the fruit falling channel 101 a .

[0074] As a preferred solution, the damping flexible fingers 102 at different heights can be divided into several layers, and each layer of damping flexible fingers 102 is set at a different position relative to the damping flexible fingers 102 of another layer, so that when the fruit falls, it receives damping at different circumferential positions at different heights, thereby achieving circumferential posture adjustment.

[0075] As a preferred solution, the damping flexible fingers 102 are constructed to have a body of revolution structure, such as a regular body of revolution such as a cone or a cylinder, or other irregular body of revolution with a curve as a generatrix.

[0076] As a further preferred solution, the damping flexible finger 102 is constructed to have at least one cylindrical surface, which can better ensure the isotropic consistency of the damping flexible finger 102 .

[0077] Specifically, the ratio of the diameter of the cylindrical surface of the damping flexible finger 102 to the length of the fruit falling channel 101a in the falling direction is in the range of 0.065 to 0.08, more preferably in the range of 0.075 to 0.08, and preferably 0.078.

[0078] Specifically, the fruit falling channel 101a is constructed as a rotating space with the central axis 101b as the axis.

[0079] Specifically, the damping flexible fingers 102 extend radially along a circle centered at a point on the central axis 101b. This maximizes the spatial damping effect of the damping flexible fingers 102. The damping flexible fingers 102 at least partially penetrate the channel device 101 and are disposed outside the channel device 101. That is, the damping flexible fingers 102 are at least partially disposed outside the channel tube, which provides for relatively stable fixation of the damping flexible fingers 102.

[0080] As a further preferred embodiment, the channel tube comprising the channel device 101 has a central axis 101b. A plurality of axially arranged damping flexible fingers 102 are provided at the same circumferential position relative to the central axis 101b. The distance between the plurality of axially arranged damping flexible fingers 102 ranges from 100 mm to 130 mm, more preferably from 115 mm to 125 mm, and preferably is 120 mm.

[0081] Similarly, multiple damping flexible fingers with different circumferential positions are provided at the same axial position relative to the central axis. The arc difference α between the multiple damping flexible fingers at the same axial position ranges from 45° to 65°, preferably 60°.

[0082] Specifically, the space in the fruit falling channel 101a that is not stopped by the damping flexible finger 102 is defined as the through space 100a. In the projection plane perpendicular to the central axis 101b, the ratio of the projection area of the through space 100a to the projection area of the fruit falling channel 101a ranges from 0.085 to 0.1, and the further preferred range is 0.09 to 0.1, and the preferred value is 0.099.

[0083] The above solution can further ensure the effect of the damping soft finger.

[0084] As a preferred solution, a bending structure 1011 is provided at both ends of the channel device 101. The bending structure 011 can effectively increase the strength of the channel device 101 and reduce the size of the fruit falling channel 101a. By controlling the size of the bending structure 1011, a fruit falling channel 101a suitable for different fruits can be constructed.

[0085] like Figures 10 to 13 As shown, the posture adjustment device 300 of this embodiment includes: a limiting device 301 and a damping brush plate 302.

[0086] Specifically, the limiting device 301 defines at least one fruit drop channel 301a through which the fruit passes as it falls. Multiple damping brush plates 302 are provided, each of which applies a damping force to the fruit in the fruit drop channel 301a, allowing the fruit to change its falling posture due to the resistance of the limiting device 301. For example, a fruit such as a grapefruit can be adjusted from a random position to a point-up position as it falls to the bottom. This adjustment is achieved due to the principle that the fruit's own damping feedback varies, allowing the fruit to fall in a stable position with its center of gravity as the center of gravity.

[0087] like Figure 13 As shown, as a specific solution, the damping brush plate 302 includes: damping bristles 3021 and a mounting clamp 3022; the damping bristles 3021 are arranged in plurality, and are arranged with one end as a fixed end and the other end as a free end, and the damping bristles 3021 are at least partially arranged in the fruit falling channel 301a; the mounting clamp 3022 is used to install one end of the damping bristles 3021 so that the damping bristles 3021 are repeatedly arranged at least in the falling direction of the fruit; specifically, the fixed end of the damping bristles 3021 is fixedly connected to the mounting clamp 3022.

[0088] Specifically, the two damping brush plates 302 form a damping partition 303 in a manner that the free ends of the damping bristles 3021 are opposite to each other, so that when the fruit falls, the opposite sides thereof are both subjected to the damping effect, thereby achieving posture adjustment.

[0089] like Figures 10 to 12As shown, as a preferred solution, a plurality of damping baffles 303 are spaced apart in the first direction of the fruit falling channel 301a. The damping bristles 3021 extend in the second direction when in their natural state. The falling direction defined by the limiting device 301 is perpendicular to both the first and second directions. This solution ensures that the fruit is damped at different positions in the first direction as it falls.

[0090] Specifically, the distance between the two damping partitions 303 ranges from 30 mm to 60 mm, more preferably from 45 mm to 55 mm, and preferably from 50 mm. This distance ensures that the falling fruit experiences an appropriate damping density in the first direction, allowing the fruit to adjust its posture while preventing excessive damping from affecting its falling speed.

[0091] Specifically, the ratio of the distance between the two damping baffles 303 to the length of the damping bristles 3021 ranges from 0.25 to 0.4, preferably from 0.30 to 0.36, and preferably 0.33. This ratio design can further ensure the effect of the damping bristles 3021.

[0092] Specifically, the ratio of the distance between the two damping baffles 303 to the length of the fruit-dropping channel 301a ranges from 0.8 to 1.2, more preferably from 0.9 to 1.1, and preferably 0.1. By using this ratio, the distance between the damping baffles 303 is designed based on the length of the fruit-dropping channel 301a, or vice versa, so that the damping density experienced by the fruit in the first direction is sufficient to achieve posture adjustment before the fruit passes through the fruit-dropping channel 301a.

[0093] Specifically, the joint of the damping bristles 3021 of the two damping brush plates 302 in a damping baffle 303 is set at the middle position of the damping baffle 303 in the second direction, so that the falling fruit is subjected to the uniform damping effect simultaneously applied by the damping bristles 3021 of the two damping brush plates 302 in a damping baffle 303.

[0094] like Figures 10 to 12 As shown, as a preferred solution, multiple damping baffles 303 are arranged in parallel.

[0095] Specifically, the damping bristles 3021 extend in a direction perpendicular to the falling direction in a natural state, so that the fruit can be subjected to continuous damping when falling.

[0096] Specifically, the length of the damping brush plate 302 ranges from 400mm to 600mm, with a further preferred range of 450mm to 550mm, and a preferred value of 500mm, thereby ensuring that the fruit can be damped for a sufficient distance in the falling direction and ensuring the posture adjustment effect.

[0097] Specifically, the aspect ratio of the damping bristles 3021 ranges from 500 to 700, more preferably from 550 to 650, and preferably is 600. This ratio design can make the damping bristles 3021 have sufficient flexibility and structural strength to complete the adjustment of the fruit posture.

[0098] Specifically, the diameter of the damping bristles 3021 ranges from 0.15 mm to 0.35 mm, with a further preferred range of 0.2 mm to 0.3 mm, and a preferred value of 0.25 mm.

[0099] like Figure 2 and Figure 3 As shown, as a preferred solution, the posture adjustment device 300 of the present application also includes: a limiting plate 304; two limiting plates 304 are provided, and the plate surfaces of the two limiting plates 304 are arranged in parallel, and at least part of the fruit falling channel 301a is located between the two limiting plates 304, thereby limiting the falling fruit in the fruit falling channel 301a.
