Description

Technical Field

[0001] This utility model relates to the field of nut production and conveying technology, specifically a conveying device for nut production with a displacement structure. Background Technology

[0002] A nut vibratory feeder is a device used for automatically arranging, placing, and conveying nuts. Nuts are vibrated within the vibratory feeder and rise along a spiral track. During this ascent, they are neatly arranged and conveyed to a first guide rail at the vibratory feeder outlet. From there, they are conveyed to a designated position for a robot to grasp. Chinese Patent No. CN202420602248.4 relates to the field of fastener conveying equipment technology, and more specifically, to a nut feeding system. This system includes a frame, a vibrating device, and a vibratory feeder. The vibratory feeder contains a material trough, and a spiral track is provided on the inner circumference of the trough. A first limiting structure extending along the direction of the spiral track is also provided on the inner circumference of the trough, forming a first limiting groove between the first limiting structure and the spiral track. The first limiting structure has an inclined surface for contacting the outer edge of the washer of a nut with the washer facing upwards. This invention overcomes the shortcomings of existing technologies where incorrect orientation of the nut washer is common, which not only affects the robot's ability to grasp the nut but also leads to incorrect nut installation. By setting a first limiting structure on the inner wall of the vibratory feeder's trough, nuts with the washer facing upwards can be removed from the spiral track, ensuring that all nuts output by the vibratory feeder have the washer facing downwards. This not only makes it easier for the robot to grasp the nut firmly but also avoids incorrect nut installation.

[0003] Based on the above, the inventors have discovered the following problem: The above device can remove nuts with the washer facing upward from the spiral track, so that all nuts output by the vibratory feeder are in the state of the washer facing downward. However, it ignores the fact that the removed nuts are still in the reverse state of the washer facing upward, and will be removed again in the vibratory feeder. This results in a large number of reverse nuts accumulating in the vibratory feeder. When the number of reverse nuts accumulates to a certain extent, it will inevitably affect the output of the forward nuts. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The present invention provides a technical solution as follows:

[0024] Example:

[0025] In this embodiment, a conveying device for producing nuts with a displacement structure includes a vibrating seat 4, a placement plate 5 at the upper end of the vibrating seat 4, a moving track 6 inside the placement plate 5, an active zone 14 connected to the upper end of the moving track 6, a stop 7 inside the active zone 14, a limiting plate 8 on one side of the stop 7 near the center of the placement plate 5, the limiting plate 8 being located on the active zone 14, a connecting plate 9 on the side of the stop 7 away from the limiting plate 8, the connecting plate 9 being located on the inner wall of the placement plate 5, a guide 15 at the lower end of the connecting plate 9, an oblique hole 32 at the lower end of the guide 15, an outlet 1 at the end of the active zone 14 away from the moving track 6, the outlet 1 being connected to an outlet channel 2, a processing device 3 on one side of the vibrating seat 4, the upper end of the processing device 3 being connected to the outlet channel 2;

[0026] The aforementioned processing device 3 is a device for processing nuts, which is existing technology and will not be described in detail here. The outlet channel 2 and outlet 1 are both used to guide the output nuts in the placement plate 5 into the processing device 3. The aforementioned vibration seat 4 is a vibration device that provides vibration in the vibratory plate. It is mentioned here for the sake of device completeness. The principle and installation method are existing and mature technologies and will not be described in detail here.

[0027] The placement plate 5 and the moving track 6 are provided with a number of nuts. Each nut includes a washer 21 and a nut block 22. The cross-sectional dimension of the washer 21 is larger than that of the nut block 22. The horizontal distance between the guide member 15 and the upper end face of the stop member 7 is equal to the cross-sectional dimension of the nut block 22. The stop member 7 is provided with a groove 23 on the side facing the guide member 15. The cross-sectional dimension of the groove 23 is equal to the horizontal length between the outer side of the washer 21 and the outer side of the nut block 22. The vertical distance between the lower end of the stop member 7 and the upper end of the movable section 14 is equal to the length of the nut block 22. The side of the limiting plate 8 facing the stop member 7 is designed with an inclined surface.

[0028] The design of the slot 23 allows the guide 15 to perform different operations on the forward and reverse nuts. When the forward nut passes through the passage 10, its lower end washer 21 can pass smoothly through the slot 23. Meanwhile, the lower end of the nut block 22 of the reverse nut is in contact with the upper side of the stop 7. Under the pushing action of the guide 15, the upper end of the reverse nut's washer 21 gradually flips towards the flipping channel 11. Under the action of the stop 7, the reverse nut flips around the side of the stop 7, causing the washer 21 of the reverse nut to flip to the limiting plate. At the upper end of 8, the reverse nut is reversed to the state where the nut block 22 faces upward. With the inclined design of the limiting plate 8, the nut can be gradually moved into the flipping channel 11 as the placement plate 5 vibrates. Then, it moves from the flipping channel 11 through the outlet 1 toward the output channel 2, thereby achieving the effect of reversing the reverse nut to the forward nut. This ensures that all the output nuts of the placement plate 5 are forward nuts, and gradually reduces the number of reverse nuts in the placement plate 5, avoiding the accumulation of reverse nuts in the placement plate 5, so that all the nuts in the placement plate 5 can be fully output.

[0029] The inclined hole 32 is provided with an air outlet pipe 31, which is connected to a telescopic air cylinder 24. The lower end of the telescopic air cylinder 24 is provided with a support base 25, and a fixed rod 29 is provided on one side of the upper end of the support base 25. A one-way air valve 30 is provided on the side of the telescopic air cylinder 24. A rotating rod 28 is movably provided at the upper end of the telescopic air cylinder 24. A movable plate is movably provided at the end of the rotating rod 28 away from the telescopic air cylinder 24. A spring 27 is provided at the lower end of the movable plate. A connecting seat 26 is connected at the lower end of the spring 27. The connecting seat 26 is located on one side of the placement plate 5. The upper end of the rotating rod 28 is movably connected to the fixed rod 29. The horizontal distance between the telescopic air cylinder 24 and the fixed rod 29 is greater than the horizontal distance between the fixed rod 29 and the spring 27. The upper surfaces of the movable section 14, the moving track 6, and the outlet 1 are all inclined, and the inclination direction is away from the central axis of the placement plate 5.

[0030] When the placement plate 5 vibrates under the action of the vibrating seat 4, it simultaneously drives the connecting seat 26 to vibrate, which in turn drives the spring 27 on it to extend and retract in the same direction. This causes the rotating rod 28 to rotate around the upper end of the fixed rod 29. Since the horizontal distance between the telescopic air cylinder 24 and the fixed rod 29 is much greater than the horizontal distance between the spring 27 and the telescopic air cylinder 24, the vertical movement of the connection between the rotating rod 28 and the telescopic air cylinder 24 is much greater than the extension and retraction of the spring 27. This allows the telescopic air cylinder 24 to be compressed, thus compressing the air inside the telescopic air cylinder 24. The air inside the telescopic air cylinder 24 is then blown out through the air outlet pipe 31 from the inclined hole 32. When the reverse nut flips under the action of the guide 15, the upward airflow from the inclined hole 32 blows towards the underside of the washer ring 21, which assists in the flipping motion of the reverse nut and makes the flipping motion of the reverse nut smoother.

[0031] With the inclined design of the moving track 6, the active area 14 and the outlet 1, when the vibration of the placement plate 5 causes the nut to vibrate, the nut will adhere to the inner wall of the placement plate 5 and move upward along the moving track 6.

[0032] The baffle 7 divides the upper surface of the movable section 14 into two movable sections on both sides of the passage channel 10 and the flip channel 11 with the axis of the baffle 7.

[0033] The above-mentioned channels 10 and 11 are as follows: Figure 2 The distribution is shown.

[0034] The lower end of the slot 23 is provided with a movable block 17, the upper end of the movable range 14 is provided with a movable groove 16, the movable block 17 is movably disposed in the movable groove 16, and a connecting shaft 18 is threadedly connected in the movable range 14. One end of the connecting shaft 18 passes through the side of the movable groove 16 and is movably connected to one side of the movable block 17. The other end of the connecting shaft 18 passes through the outside of the placement plate 5 and is provided with a rotating handle 12.

[0035] Through the design of the movable groove 16, movable block 17, and connecting shaft 18, rotating the rotating handle 12 can drive the connecting shaft 18 to rotate within the movable range 14, thereby pushing the movable block 17 to move within the movable groove 16, thus adjusting the width of the passage 10 and accommodating nuts of different sizes.

[0036] The guide member 15 has a pair of connecting posts 20 at its upper end. The upper end of the connecting post 20 passes through the connecting plate 9 and extends out of the upper end of the connecting plate 9. A torsion member 13 is provided at the upper end of the connecting post 20. The connecting post 20 is threadedly connected to the connecting plate 9 and is movably connected to the guide member 15. An adjustment groove 19 is provided on the inner wall of the placement plate 5. One side of the guide member 15 is movably disposed in the adjustment groove 19.

[0037] By designing a pair of connecting posts 20, the torsion member 13 can be rotated to drive the connecting posts 20 to move vertically within the connecting plate 9, thereby driving the guide member 15 to move vertically. This allows the vertical distance of the guide member 15 to be adjusted. Combined with the adjustable stop member 7, this device can adapt to nuts of different heights and widths, thus giving it a wide range of applications and allowing it to be adjusted according to different types of nuts.

[0038] The torsion member 13 and the connecting plate 9, the rotating handle 12 and the side wall of the placement plate 5 are all provided with damping; the design of damping on the side of the torsion member 13 and the connecting plate 9, and the torsion member 13 and the placement plate 5 can prevent the torsion member 13 and the connecting plate 9, and the torsion member 13 and the placement plate 5 from reversing.

[0039] The spring 27 is provided with a limiting post, which is located at the upper end of the connecting seat 26;

[0040] By incorporating a limiting post within the spring 27, the direction of movement of the spring 27 can be restricted, allowing the spring 27 to move vertically.

[0041] Working Principle: In use, the nut is poured into the middle of the placement plate 5. The vibration of the vibrating seat 4 causes the placement plate 5 to vibrate. The inclined design of the moving track 6, the active zone 14, and the outlet 1 ensures that when the placement plate 5 vibrates, the nut adheres to the inner wall of the placement plate 5 and moves upwards along the moving track 6. When the nut is in a forward direction (waist ring 21 at the lower end and nut block 22 at the upper end), it enters the active zone 14, passes through the passage channel 10, directly through the outlet 1, and moves towards the discharge channel 2. When the nut is in a reverse direction (waist ring 21 at the upper end and nut block 22 at the lower end), it first enters the entrance of the passage channel 10. At this time, the side of the nut block 22 at the lower end of the reverse nut adheres to the side of the stop 7. Then, the washer ring 21 at the upper end of the reverse nut is guided by the guide member 15, the shape of which is as follows: Figure 5 and Figure 1As shown, the reverse nut is inclined towards the flipping channel 11, and under the design of the limiting plate 8 and the stop 7, the reverse nut will rotate around the side of the stop 7. With the cooperation of the rotating rod 28 and the telescopic air cylinder 24, when the reverse nut flips under the action of the guide 15, the upward airflow from the inclined hole 32 blows towards the underside of the washer 21, thus assisting the flipping motion of the reverse nut and making the flipping motion of the reverse nut smoother. When one end of the washer 21 at the upper end of the reverse nut flips to the side of the limiting plate 8, and the nut block 22 flips to the upper end of the washer 21, at this time... Under the continuous vibration of the placement plate 5, and with the limiting plate 8 being an inclined surface, the nut that has been flipped to the positive direction can be gradually moved from the side of the limiting plate 8 into the flipping channel 11, so that the nut in the flipping channel 11 is in the positive state. Then, the nut also moves through the outlet 1 to the outlet channel 2, thereby realizing the flipping operation of the reverse nut, so that the output nuts of the placement plate 5 are all positive nuts, which facilitates the next step of processing of the nuts. Compared with the traditional method of removing the reverse nuts, the nuts in the placement plate 5 can be completely output, avoiding the accumulation of reverse nuts in the placement plate 5 and affecting the output effect of the placement plate 5.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
