Description

Technical Field

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

[0002] In recent years, a large number of large-scale, high-standard, intensive pomelo production bases have emerged. Import and export volumes are increasing, and the quality requirements for pomelo products are becoming increasingly stringent. This has led to a strong demand for quality inspection and finished product packaging. These requirements all require the fruit to be grown 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

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] like Figures 1 to 4 As shown, the posture adjustment device 200 of the present application includes: a channel device 201. The channel device 201 provides at least one fruit falling channel 201a for fruits to pass through when falling.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] As a preferred solution, Figures 1 to 4 As shown, 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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°.

[0049] 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 500 3 to 550 3 , the preferred value is 531 3 .

[0050] 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.

[0051] As a more specific solution, the channel device is also provided with a medium source interface 201e, in particular, an air source interface; the interlayer space 201c connects multiple medium channels 201b to the medium source interface 201e (air source interface); and the medium channel 201b is connected to the fruit falling channel 201a.

[0052] The above descriptions are merely some preferred embodiments of the present disclosure and illustrate the underlying technical principles. Those skilled in the art should understand that the scope of the invention encompassed by the embodiments of the present disclosure is not limited to technical solutions formed by specific combinations of the aforementioned technical features. It also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents, without departing from the aforementioned inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
