[0001] The invention relates to the technical field of grapefruit packaging production, in particular to a full-automatic grapefruit orientation adjusting machine. Background Art

[0002] my country is a major producer of grapefruit. Currently, the production and packaging of grapefruit cannot be completely completed by machines, especially in the process of adjusting the orientation of grapefruit. This is because the postures of grapefruits are different when they are moved out from the conveyor rollers. In order to prevent packaging unit errors or unsatisfactory packaging effects due to the messy postures of grapefruits during labeling and wrapping, the grapefruits need to be adjusted to a unified posture, which relies on a large amount of manual participation to complete, which is time-consuming and labor-intensive, and has low production efficiency. Summary of the invention

[0003] The invention aims to overcome the defects of the prior art and provide a fully automatic grapefruit orientation adjusting machine with high production efficiency and low labor intensity.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fully automatic grapefruit direction-adjusting machine comprises a conveying frame, a horizontal frame is fixedly connected to one side of the conveying frame, an arc slide is arranged at one end of the horizontal frame close to the conveying frame, and a driving mechanism for pushing the grapefruit into the arc slide is also arranged on the horizontal frame. A left baffle plate and a right baffle plate are symmetrically arranged at one end of the arc slide away from the horizontal frame, the bottoms of the left baffle plate and the right baffle plate both extend inwardly, and the spacing between the bottoms of the left baffle plate and the right baffle plate is slightly smaller than the width of the large end of the grapefruit, an adjusting slide is arranged directly below the left baffle plate and the right baffle plate, the adjusting slide is connected to the end of the conveying frame away from the horizontal frame through a torsion spring, a conveyor belt is arranged directly below the adjusting slide, and the arc slide and the adjusting slide are both composed of a plurality of symmetrically arranged arc bars.

[0005] A further solution is that there are five arc bars, the arc bar in the middle has the smallest curvature, and the arc bars on both sides have increasing curvatures.

[0006] A further solution is that a front baffle is provided at the conveyor frame near the ends of the left baffle and the right baffle, and a rear baffle is provided at the conveyor frame near the end of the conveyor belt.

[0007] A further solution is that a pneumatic clamp is also installed on the conveyor frame, and the output end of the pneumatic clamp is connected to the left baffle and the right baffle respectively to adjust the distance between the left baffle and the right baffle.

[0008] A further solution is that the driving mechanism includes a cylinder and a horizontal slide, the horizontal slide is arranged on a horizontal frame and connected to the arc slide, the cylinder is installed on the horizontal slide, and the output end of the cylinder is fixedly connected to a push plate.

[0009] A further solution is that an arc-shaped frame is arranged on one side of the horizontal frame, an arc-shaped slide is arranged on the arc-shaped frame, and the bottom end of the arc-shaped slide is connected to the horizontal slide.

[0010] A further solution is that the model of the pneumatic gripper is MHL2-16D2.

[0011] A further solution is that a sprocket is provided at one end of the conveyor belt, and the sprocket is used to drive the conveyor belt to move forward, and the sprocket is connected to an output end of a motor fixed on a conveyor frame through a chain.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of the arc slide, pneumatic clamp, left baffle, right baffle and adjustment slide, torsion spring, driving mechanism and the shape of the grapefruit, the grapefruit first enters the arc slide under the action of the driving mechanism, and because the arc slide is symmetrically arranged, the grapefruit passing through the arc slide is adjusted to be symmetrically arranged with the center of the arc slide, that is, the small head or the large head is located at the front end; then it slides forward to the left baffle and the right baffle, and because the left baffle and the right baffle only support the grapefruit The center of gravity of the grapefruit is unstable at the edge of the big end. Under the action of the grapefruit's own gravity, the small end of the grapefruit rotates downward, so that the small end of the grapefruit is downward and the big end is upward, completing the first adjustment. Then the pneumatic gripper adjusts the distance between the left baffle and the right baffle so that it no longer supports the grapefruit, causing the grapefruit to fall onto the adjustment slide. Under the action of the grapefruit's own gravity, the bottom of the adjustment slide is driven to rotate downward, ensuring that the grapefruit falls onto the conveyor belt with the small end facing right and the big end facing left, thus completing the automatic adjustment of the grapefruit. The adjustment machine overcomes the shortcomings of high labor intensity and low adjustment efficiency of traditional manual loading. The equipment has a simple structure, which is conducive to later maintenance and replacement. It has the advantages of high production efficiency, environmental protection, and low processing cost.

DETAILED DESCRIPTION

[0018] The following is combined with Figures 1 to 4 The present invention is described in further detail.

[0019] A fully automatic grapefruit direction-adjusting machine includes a conveyor frame 10, a horizontal frame 4 is fixedly connected to one side of the conveyor frame 10, an arc frame 1 is arranged on one side of the horizontal frame 4, an arc slide 2 and a fixed baffle 3 are arranged on the arc slide 2, and the fixed baffle 3 is located above the arc slide 2; a horizontal slide 5 is arranged on the horizontal frame 4, and the bottom end of the arc slide 2 is connected to the horizontal slide 5. An arc slide 9 is arranged at one end of the horizontal frame 4 close to the conveyor frame 10, and a driving mechanism for pushing grapefruit into the arc slide 9 is also arranged on the horizontal frame 4, the driving mechanism includes a cylinder 8 and the horizontal slide 5, the cylinder 8 is installed on the horizontal slide 5, a push plate 7 is fixedly connected to the output end of the cylinder 8, cylinder baffles 6 are arranged on both sides of the cylinder 8, the cylinder 8 drives the push plate 7 to move, and the push plate 7 pushes the grapefruit into the arc slide 9, and the arc slide 9 is composed of a plurality of symmetrically arranged arc bars 22.

[0020] Please see attached Figure 4 There are five arc bars 22, the arc bar 22 in the middle has the smallest arc, and the arc bars 22 on both sides have increasing arcs. It can be understood that such a setting can prevent the grapefruit from sliding out of the arc bar slide 9, and because the arc bar slide 9 is symmetrically arranged, the grapefruit passing through the arc bar slide 9 is adjusted to be symmetrically arranged with the center of the arc bar slide 9, that is, the small head or the large head is located at the front end.

[0021] See also Figures 1 to 3The conveyor frame 10 is provided with a pneumatic clamp 11 at one end thereof close to the arc slideway 9 and away from the horizontal frame 4. The model of the pneumatic clamp 11 is MHL2-16D2. The output ends of the pneumatic clamp 11 are respectively fixedly connected with a symmetrically arranged left baffle 12 and a right baffle 13. The bottoms of the left baffle 12 and the right baffle 13 are both bent inwards, and the distance between the bottoms of the left baffle 12 and the right baffle 13 is slightly smaller than the width of the big end of the grapefruit, so that the left baffle 12 The right baffle plate 13 can only support the edge of the large end of the pomelo. The pomelo that slides from the arc slideway 9 to the left baffle plate 12 and the right baffle plate 13 will have an unstable center of gravity. Under the action of the pomelo's own gravity, the small end of the pomelo rotates downward, so that the small end of the pomelo is facing downward and the large end is on top, completing the first direction adjustment. Then the pneumatic clamp 11 adjusts the distance between the left baffle plate 12 and the right baffle plate 13, so that the left baffle plate 12 and the right baffle plate 13 no longer support the pomelo, and the pomelo will fall downward. An adjusting slide 15 is arranged directly below the left baffle 12 and the right baffle 13. The adjusting slide 15 is connected to the end of the conveying frame 10 away from the horizontal frame 4 through a torsion spring 16. A conveyor belt 18 is arranged directly below the adjusting slide 15. The adjusting slide 15 is also composed of 5 symmetrically arranged arc bars 22. The arc bar 22 located in the middle has the smallest arc, and the arc bars 22 on both sides have increasing arcs. After the grapefruit falls on the adjusting slide 15, under the action of the grapefruit's own gravity, the bottom end of the adjusting slide 15 is driven to rotate downward to ensure that the grapefruit falls on the conveyor belt 18 with the small head facing right and the large head facing left, thereby completing the automatic adjustment of the grapefruit. Furthermore, before the adjusting slide 15 is in motion, it is located at the upper limit position. When the grapefruit falls on it, it is pressed to the lower limit position. Then, after the grapefruit slides down from the adjusting slide 15, the adjusting slide 15 will return to the upper limit position, so that the grapefruit can be smoothly conveyed forward on the conveyor belt 18.

[0022] Please continue reading Figures 1-2 The conveyor frame 10 is provided with a front baffle 14 near the end of the left baffle 12 and the right baffle 13 to prevent the grapefruit from sliding out of the left baffle 12 and the right baffle 13 . The conveyor frame 10 is provided with a rear baffle 17 near the end of the conveyor belt 18 to prevent the grapefruit from sliding out of the conveyor belt 18 .

[0023] Please continue reading Figure 1 A sprocket 19 is provided at one end of the conveyor belt 18, and the sprocket 19 is used to drive the conveyor belt 18 to move forward. The sprocket 19 is connected to the output end of the motor 21 fixed on the conveyor frame 10 through a chain 20.

[0024] The specific working process of the present invention is as follows: the grapefruits enter the horizontal slide 5 in an orderly manner through the arc slide 2, and are pushed into the arc slide 9 by the push plate 7, and the grapefruits are adjusted so that the small end or the large end is located at the front end, and then slide onto the left baffle 12 and the right baffle 13. Under the action of the grapefruit's own gravity, the small end of the grapefruit rotates downward, so that the small end of the grapefruit is downward and the large end is at the top, completing the first adjustment, and then the pneumatic clamp 11 adjusts the distance between the left baffle 12 and the right baffle 13 so that the left baffle 12 and the right baffle 13 are The right baffle 13 no longer supports the grapefruit, and the grapefruit will fall downward; the torsion spring 16 controls the adjusting slide 15 to be in the upper limit position, and the grapefruit falls into the adjusting slide 15 after the first adjustment and presses the adjusting slide 15 to the lower limit position under the action of its own gravity, ensuring that the grapefruit falls onto the conveyor belt 18 with the small end facing right and the large end facing left, thereby completing the automatic adjustment of the grapefruit. Without the pressure of the grapefruit, the adjusting slide 15 returns to the upper limit position, allowing the grapefruit to pass smoothly under the adjusting slide 15 on the conveyor belt 18.

[0025] The above implementation is used to illustrate the technical solution of the present invention rather than to limit it. Those skilled in the art should understand that any modification, equivalent substitution or improvement of the technical solution of the present invention within the spirit and principle of the present invention is included in the protection scope of the present invention.
