Description

Technical Field

[0001] The invention relates to the technical field of vehicle tire conveying, and in particular to a rubber tire conveying device. Background Art

[0002] Tire conveying is an important part of the automotive manufacturing process, involving the conveying of tires from storage or production to assembly or testing. This process usually uses special conveying equipment, such as tire conveyor lines, screw conveyors or mesh belt lines. These equipment are designed to meet the special needs of tires, including their large size, weight and the need for error-proof sorting according to vehicle models.

[0003] Tire conveyor lines usually choose suspended conveyor lines, which usually include a U-shaped frame installed under the conveying track. Both ends of the frame are provided with pallets under the tire. During use, the tire is moved between the two pallets and placed on the pallets. After that, the tire can be transported to the specified position through the conveying track. However, since the specifications of the frame are fixed, the distance between the two relatively set pallets is fixed. During use, only frames of corresponding sizes can be made according to the diameters of different tires to transport tires of different diameters. At the same time, since the two pallets can only support the tires on both sides of the tire, the tires are easy to slide out from the other two sides. It is also necessary to set a support net under the conveying track to prevent the fallen tires from falling. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] Embodiment 1:

[0036] A rubber tire conveying device, such as Figure 1-3 As shown, it includes a conveying platform 1, which is used to convey tires 3 over a short distance. When in use, a worker conveniently places the tire 3 on one end of the conveying platform 1. A lifting frame 2 is provided on one side of the conveying platform 1. The lifting frame 2 is used to receive the tire 3 conveyed by the conveying platform 1 and drive the tire 3 to move to a specified height.

[0037] A top frame 4 is distributed along the length direction of the conveying platform 1 and is located directly above the conveying platform 1. A plurality of U-shaped conveying frames 5 are arranged at intervals below the top frame 4. The U-shaped conveying frames 5 are used to fix the tires 3, and the top frame 4 is used to drive the U-shaped conveying frames 5 to move;

[0038] Among them, after the conveying platform 1 conveys the tire 3 to the specified position on the lifting frame 2 (a lifting plate 21 is provided on the lifting frame 2, and the lifting plate 21 supports the inner ring of the tire 3 when supporting the tire 3), the lifting frame 2 drives the tire 3 to move upward to the inside of the U-shaped conveying frame 5 for fixing. After the U-shaped conveying frame 5 stably fixes the tire 3, the top frame 4 conveniently drives the U-shaped conveying frame 5 to drive the tire 3 to be conveyed; the way in which the top frame 4 drives the U-shaped conveying frame 5 to move is a mature conveying mechanism in the prior art, which can be referred to by searching for "suspension conveyor line" and will not be described in detail here;

[0039] Among them, the U-shaped conveying frame 5 includes two relatively connected bending rods 51, and the lower ends of the two bending rods 51 are relatively provided with support plates 52. The two bending rods 51 are connected to each other with an extension tube 53. The extension tube 53 is slidably provided with a sliding rod 6 on the side away from the U-shaped conveying frame 5. The sliding rod 6 is used to clamp the tire 3 located on the U-shaped conveying frame 5.

[0040] The central axis of the extension tube 53 is perpendicular to the two bending rods 51 in a top view; the distance between the lower ends of the two bending rods 51 is smaller than the diameter of the tire 3;

[0041] In the present invention, the sliding rod 6 is slidably arranged, and when the tire 3 is driven by the lifting frame 2 to move into the interior of the U-shaped conveying frame 5, the sliding rod 6 is then driven to move toward the U-shaped conveying frame 5, and the tire 3 is pushed to a state of being close to the support plate 52, and the tire 3 is supported and fixed from three directions respectively, so that tires 3 of different diameters can be conveniently fixed (the use state of the U-shaped conveying frame 5 can be adjusted after the diameter of the tire 3 changes, such as Figure 8 As shown in the figure, the tires 3 of different diameters can be fixed by simply moving the sliding rod 6, and shaking of the tire 3 during the conveying process can be avoided, thereby reducing the risk of the tire 3 falling off the U-shaped conveying frame 5.

[0042] Furthermore, if Figure 4 As shown, the extension tube 53 is provided with a telescopic member 54 for driving the sliding rod 6 to move closer to or away from the extension rod 53. The side view projection contour of the sliding rod 6 is L-shaped, and the lower end of the sliding rod 6 is rotatably mounted with a rotating plate 61 supported under the tire 3.

[0043] The rotating plate 61 and the two supporting plates 52 are located at the same level, and the rotating plate 61 and the two supporting plates 52 are respectively supported at three positions at the bottom of the tire 3, so that the tire is more stably placed inside the U-shaped conveyor frame 5;

[0044] Furthermore, one end of the sliding rod 6 extends into the interior of the extending tube 53 , and one end of the sliding rod 6 slides inside the extending tube 53 .

[0045] Among them, by extending one end of the sliding rod 6 into the extension tube 53 for sliding installation, the extension tube 53 can provide a good support effect on the sliding rod 6, and can also conveniently guide the sliding of the sliding rod 6. In actual use, the telescopic member 54 can be an electric telescopic rod or a small hydraulic telescopic rod. The telescopic member 54 can be arranged inside the extension tube 53, which can provide good protection for the telescopic member 54. The telescopic member 54 can also be pushed toward the middle of the sliding rod 6 to reduce the friction between the sliding rod 6 and the inner wall of the extension tube 53.

[0046] Furthermore, a rotating shaft 62 is provided below the sliding rod 6, the central axis of the rotating shaft 62 is perpendicular to the extending tube 53, the tail of the rotating plate 61 is rotatably connected to the rotating shaft 62, the rotation direction of the rotating plate 61 is toward the direction of the U-shaped conveying frame 5, and telescopic rods 65 are provided on both sides of the sliding rod 6, and the telescopic rods 65 are used to drive the rotating plate 61 to rotate toward the U-shaped conveying frame 5.

[0047] In the initial state, the rotating plate 61 is in a vertical state. After the tire 3 reaches a specified height, the rotating plate 61 is driven by the telescopic rod 65 to rotate toward the U-shaped conveying frame 5, and one end of the rotating plate 61 facing the U-shaped conveying frame 5 is supported at the bottom of the tire 3; then, driven by the telescopic member 54, the sliding rod 6 above the rotating plate 61 moves toward the direction of the U-shaped conveying frame 5, so that the rotating plate 61 in a horizontal state slides at the bottom of the tire 3 and gradually clamps the tire 3;

[0048] Furthermore, if Figure 5 As shown, one end of the rotating plate 61 away from the rotating shaft 62 is in an upwardly inclined convex shape, and the upper end surface of the rotating plate 61 is provided with a negative pressure groove 6101 for adsorbing the tire 3, and a negative pressure pipe 63 is provided below the negative pressure groove 6101, and the other end of the negative pressure pipe 63 is connected to an external air extraction device; a rubber ring 64 for sealing is provided at the notch position of the negative pressure groove 6101.

[0049] It should be noted that when the rotating plate 61 is supported on the bottom of the tire 3 and moves toward the direction of the tire 3, the negative pressure groove 6101 on the rotating plate 61 generates a negative pressure space during the continuous extraction of air by the negative pressure tube 63, which adsorbs the tire 3 placed on the rotating plate 61, so that the tire 3 can be more stably fixed above the rotating plate 61 and the two support plates 52.

[0050] Embodiment 2:

[0051] Furthermore, if Figure 4 , Figure 5As shown, a cleaning chute 6102 is arranged above the rotating plate 61, and the cleaning chute 6102 is located on the side of the negative pressure groove 6101 away from the rotating shaft 62. A cleaning component 66 is arranged inside the cleaning chute 6102, and the cleaning component 66 is used to clean the dust on the part of the tire 3 that is aligned with the negative pressure groove 6101.

[0052] Among them, the cleaning chute 6102 is located on the side of the negative pressure groove 6101 away from the rotating shaft 62. After the cleaning component 66 inside the cleaning chute 6102 cleans a part of the lower surface of the tire 3, the cleaned part will then move to the top of the negative pressure groove 6101 to accurately clean the adsorbed part.

[0053] Furthermore, if Figure 7 , Figure 8 As shown, the cleaning assembly 66 includes a cleaning shaft 661 rotatably mounted inside the cleaning chute 6102, and the outer side of the cleaning shaft 661 is sleeved with a cleaning brush plate 662 for contacting and cleaning the surface of the tire 3 (the end face of the cleaning brush plate 662 away from the cleaning shaft 661 is provided with multiple rows of bristles, and the bristles can clean up the dust or rubber particles remaining on the tire 3 to avoid additional air leakage in these gaps during the adsorption process), and both ends of the cleaning shaft 661 extend into the cavity inside the rotating plate 61, and both ends of the cleaning shaft 661 are provided with a steering adjustment mechanism 663 for changing the rotation direction, and the side of the steering adjustment mechanism 663 is provided with a driving wheel 67 for driving the cleaning shaft 661 to rotate.

[0054] Furthermore, two strip-shaped through holes 6103 are provided on the rotating plate 61 , and the strip-shaped through holes 6103 are used to accommodate the top of the driving wheel 67 extending out of the rotating plate 61 . The two strip-shaped through holes 6103 are respectively located on both sides of the cleaning chute 6102 .

[0055] Furthermore, the steering adjustment mechanism 663 includes two gears meshing with each other, wherein one gear is disposed on the cleaning shaft 661 , and the other gear is disposed coaxially with the driving wheel 67 .

[0056] When the rotating plate 61 rotates to the bottom of the tire 3 and moves toward the tire 3 driven by the sliding rod 6, the bottom of the tire 3 is against the upper end surface of the rotating plate 61. At this time, the top of the driving wheel 67 is in contact with the tire 3. At this time, the movement of the rotating plate 61 causes the driving tire 67 and the lower surface of the tire 3 to rotate under the action of friction, so that the driving wheel 67 can easily drive the cleaning shaft 661 to rotate without the need for additional power.

[0057] In the present invention, by setting two gears that mesh with each other to adjust the rotation of the driving wheel 67, the rotation direction of the cleaning shaft 661 can be opposite to the rotation direction of the driving wheel 67, and the cleaning brush plate 662 on the cleaning shaft 661 can be moved toward the side away from the rotating shaft 62 to clean the dust on the lower surface of the tire 3, which can reduce the air leakage generated by the negative pressure groove 6101 when adsorbing the tire 3, thereby enhancing the adsorption effect of the negative pressure groove 6101 on the tire 3.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
