Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, specifically to a tire manufacturing centering device. Background Technology

[0002] In a tire production line, finished tires are conveyed via a roller conveyor. At the rear end of the roller conveyor, a handling robot picks up the tires and moves them to the next process. However, the tires may not be on the center line of the roller conveyor. If the tires are not on the center line, the handling robot cannot pick them up because the program is fixed, which will affect the production process. Therefore, the tires need to be aligned and adjusted.

[0003] Chinese patent CN208470922U discloses a tire alignment device for a tire production line, comprising: two parallel baffles, a chute, a slider, and a cylinder. When the conveyor rollers transport the tire between the two baffles, the piston rod of the cylinder drives a push plate to extend outward, and the two push plates contact both sides of the tire. Since the two baffles are symmetrically arranged with respect to the center of the rollers and the stroke specifications of the two cylinders are identical, the two push plates drive the tire to the center position of the conveyor rollers during their movement. When the push plate is in full contact with the tire, the friction between the tire and the push plate causes the slider to slide backward along the chute and stretch the spring. As the push plate moves backward following the tire, it avoids the situation where the tire slides and rubs against the rollers on the conveyor rollers after clamping, thus preventing tire scratches.

[0004] However, the current centering device has the following problems: In the tire production process, there are often tires of different sizes and specifications. When it is necessary to produce tires of different specifications, the centering device is not convenient to adaptively center tires of different sizes and specifications, which leads to certain limitations in the use of the centering device. Therefore, we propose a tire production centering device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a tire production centering device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tire production centering device, comprising a frame, wherein a conveyor belt assembly for transporting tires is disposed inside the frame, and a centering device is disposed in the middle of the frame, the centering device comprising a U-shaped frame, the U-shaped frame being fixed to the top of the frame, two rotating columns being rotatably mounted on both sides of the top of the inner wall of the U-shaped frame, and a spiral frame being fixed on the side of each of two adjacent rotating columns that are far apart from each other, a plurality of abutment rollers being rotatably mounted inside each of the four spiral frames, and a sliding column being fixed to the top of each of the four spiral frames, an electric push rod being fixed to the middle of the top of the U-shaped frame, a horizontal plate being fixed to the top of the telescopic end of the electric push rod, and long groove plates being slidably mounted on both sides of the top of the U-shaped frame, the long groove plates being hinged to the outer wall of the horizontal plate by a hinge rod, and the sliding column being slidably mounted inside the long groove plate.

[0007] According to the above technical solution, the conveyor belt assembly includes two conveyor rollers that are rotatably installed inside the frame, and several conveyor belts that are drive-connected to the outside of the two conveyor rollers. Each conveyor roller is driven by a motor, and the several conveyor belts are evenly and equidistantly distributed outside the two conveyor rollers.

[0008] According to the above technical solution, a lifting device is provided at the U-shaped frame. The lifting device includes a spiral slide, which is slidably installed on the outer wall of the U-shaped frame. A spring is provided between the bottom of the spiral slide and the outer wall of the U-shaped frame. Several receiving boxes are evenly and equidistantly fixed on the top of the spiral slide. The several receiving boxes are located between several transmission belt spacings of the transmission belt group. Top rollers are rotatably installed inside the several receiving boxes. A U-shaped push rod is fixed on the top of the spiral slide.

[0009] According to the above technical solution, the middle part of the U-shaped push rod is arranged in an inverted trapezoidal shape, and the inclined surfaces on both sides of the inverted trapezoid of the U-shaped push rod are respectively located on the motion trajectory of the long slot plate on both sides.

[0010] According to the above technical solution, a spacing device is provided at the U-shaped frame. The spacing device includes a geometric push rod and two elastic telescopic rods. The fixed ends of the two elastic telescopic rods are respectively fixed to the outer walls of the two U-shaped frames located in the forward direction of the tire. The telescopic ends of the two elastic telescopic rods are each fixed with a push plate. The push plate is located in the forward direction of the tire. A fixed column is fixed to the top of the push plate. The geometric push rod is slidably installed on the top of the U-shaped frame. The top of the geometric push rod is hinged to the outer wall of the horizontal plate through a hinged telescopic rod.

[0011] According to the above technical solution, the bottom of the horizontal rods on both sides of the geometric push rod is on the same horizontal plane as the top of the long slot plate, and the fixing column is located on the movement trajectory of the horizontal rods on both sides of the geometric push rod.

[0012] According to the above technical solution, the middle part of the geometric push rod is arranged in an inverted U-shape, and the inverted U-shape of the geometric push rod is used to prevent the presence of the geometric push rod from interfering with the operation of the U-shaped push rod.

[0013] According to the above technical solution, the U-shaped frame is provided with an anti-parallelism device in the direction of tire movement. The anti-parallelism device includes two F-shaped rods respectively fixed to the top of two long groove plates. T-shaped columns are slidably installed on the side of the two F-shaped rods that are far apart from each other. Clamping plates are fixed on the side of the two T-shaped columns that are close to each other. Springs are provided between the clamping plates and the F-shaped rods.

[0014] This invention provides a tire manufacturing centering device. It has the following beneficial effects:

[0015] (1) The present invention, through the setting of the centering device, enables the electric push rod, the horizontal plate, the hinge rod, the long groove plate, the sliding column, and the return frame to work together to drive the contact roller to push the tire to center in the middle position of the conveyor belt group. At the same time, the return frame and the contact roller can automatically adjust the centering position of the tire according to the size and specifications of the tire, so that the centering device can adapt to tires of different sizes without being limited by a fixed size.

[0016] (2) By setting up the lifting device, the long groove plate, U-shaped push rod, U-shaped slide, U-shaped frame and receiving box work together to drive the top roller to lift the tire at the U-shaped frame. The tire does not contact the top of the conveyor belt group, so that the tire will not be affected by the friction of the surface of the conveyor belt group during the centering process. This allows the tire to be more accurately controlled by the U-shaped frame. This helps the U-shaped frame drive the abutment roller to better adjust the position of the tire, ensuring that the tire always stays in the center position of the conveyor belt group. Furthermore, by lifting the tire with the top roller, the problem of poor tire movement or deviation caused by excessive friction or jamming between the tire and the conveyor belt group can be avoided.

[0017] (3) By setting up a lifting device, the present invention enables the push plate, the elastic telescopic rod, the push plate, the fixed column, the electric push rod, the horizontal plate, the hinge rod, the geometric push rod, and the fixed column to work together to drive the push plate to push the tire in front of the tire that needs to be centered to move away from the U-shaped frame. The front tire is away from the two front U-shaped frames, thereby avoiding the problem that the conveyor belt group will move the front tire between the two front U-shaped frames, which would hinder the swing of the U-shaped frame and affect the function of the U-shaped frame to drive the contact roller to adjust the tire. This ensures that the U-shaped frame can swing freely and work according to the predetermined trajectory, thereby accurately centering the tire.

[0018] (4) By setting up an anti-parallelism device, the present invention enables the long groove plate, F-shaped rod, frame, and T-shaped column to work together to drive the clamping plate to pre-clamp multiple tires on the front side, thereby ensuring that they will not be misaligned or overlapped under the push of the push plate. This can greatly improve the positioning accuracy of each tire during the transmission process, avoid the offset or misalignment problem caused by the parallel transmission of tires, and enable the tires to maintain the correct position in subsequent alignment operations. At the same time, the spring between the clamping plate and the F-shaped rod allows the clamping plate to adaptively pre-clamp tires of different sizes and specifications.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-7One embodiment of the present invention is: a tire production centering device, including a frame 1, a conveyor belt assembly 2 for transporting tires is arranged inside the frame 1, a centering device 3 is arranged in the middle of the frame 1, the centering device 3 includes a U-shaped frame 31, the U-shaped frame 31 is fixed to the top of the frame 1, two rotating columns 32 are rotatably installed on both sides of the top of the inner wall of the U-shaped frame 31, and a loop frame 33 is fixed on the side of each pair of adjacent rotating columns 32 that are far apart from each other, a plurality of abutment rollers 34 are rotatably installed inside the four loop frames 33, a sliding column 39 is fixed on the top of each of the four loop frames 33, an electric push rod 35 is fixed in the middle of the top of the U-shaped frame 31, a cross plate 36 is fixed on the top of the telescopic end of the electric push rod 35, and the top sides of the U-shaped frame 31 are slidably installed The system includes a long groove plate 38, which is hinged to the outer wall of the horizontal plate 36 via a hinge rod 37. A sliding column 39 is slidably installed inside the long groove plate 38. The conveyor belt group 2 includes two conveyor rollers that are rotatably installed inside the frame 1, and several conveyor belts that are drively connected to the outside of the two conveyor rollers. Each conveyor roller is driven by a motor, and the several conveyor belts are evenly and equidistantly distributed outside the two conveyor rollers. With the above structure, the return frame 33 drives the contact roller 34 to push the tire to the center position in the middle of the conveyor belt group 2. At the same time, the return frame 33 and the contact roller 34 can automatically adjust the centering position of the tire according to the size and specifications of the tire, so that this centering device 3 can adapt to tires of different sizes without being limited by a fixed size.

[0029] A lifting device 4 is provided at the U-shaped frame 31. The lifting device 4 includes a spiral slide 41, which is slidably installed on the outer wall of the U-shaped frame 31. A spring is provided between the bottom of the spiral slide 41 and the outer wall of the U-shaped frame 31. Several receiving boxes 43 are evenly and equidistantly fixed at the top of the spiral slide 41. The receiving boxes 43 are located between several transmission belt spacings of the transmission belt group 2. Top rollers 44 are rotatably installed inside each receiving box 43. A U-shaped push rod 42 is fixed at the top of the spiral slide 41. The middle part of the U-shaped push rod 42 is set in an inverted trapezoid. The inclined surfaces on both sides of the inverted trapezoid of the U-shaped push rod 42 are respectively located on the movement trajectory of the long groove plate 38 on both sides. Through the above structure, the top rollers 44 will lift the tire at the U-shaped frame 31, and the tire will not contact the top of the transmission belt group 2. Thus, the tire will not be affected by the friction of the surface of the transmission belt group 2 during the centering movement, so it can be more accurately controlled by the spiral frame 33.

[0030] In use, start the conveyor belt assembly 2, place the tire on the conveyor belt assembly 2, and the conveyor belt assembly 2 will then transport the tire. When the conveyor belt assembly 2 moves the tire to the U-shaped frame 31, the conveyor belt assembly 2 stops operating, and the electric push rod 35 is activated. The telescopic end of the electric push rod 35 pushes the horizontal plate 36 upward. The horizontal plate 36 pulls the long groove plate 38 along the top of the U-shaped frame 31 towards the center of the U-shaped frame 31 via the hinge rod 37. The long groove plate 38 pushes the sliding column 39 along the inside of the long groove plate 38. The sliding plate 38 pushes the sliding column 39 to drive the return frame 33 to swing towards the center of the U-shaped frame 31. The return frame 33 drives the contact roller 34 to abut against the tire that has moved to the U-shaped frame 31. The return frame 33 drives the contact roller 34 to push the tire to center in the middle position of the conveyor belt group 2. At the same time, the return frame 33 and the contact roller 34 can automatically adjust the centering position of the tire according to the size and specifications of the tire, so that the centering device 3 can adapt to tires of different sizes without being limited by a fixed size.

[0031] During each movement of the long groove plate 38 along the top of the U-shaped frame 31 towards its center, the long groove plate 38 pushes the inverted trapezoidal slope of the U-shaped push rod 42, causing the U-shaped push rod 42 to move upward. The U-shaped push rod 42 then causes the loop carriage 41 to slide upward along the outer wall of the U-shaped frame 31, and the corresponding spring of the loop carriage 41 is stretched. The loop carriage 41 then drives the top roller 44 to move upward through the receiving box 43, causing the top roller 44 to protrude beyond the top horizontal plane of the conveyor belt group 2. The top roller 44 will then move the top roller 44, which is located on the U-shaped frame 31, upward. The tire is lifted up so that it does not contact the top of the conveyor belt assembly 2. This prevents the tire from being affected by friction on the surface of the conveyor belt assembly 2 during its central movement, allowing for more precise control by the guide frame 33. This helps the guide frame 33 drive the abutment roller 34 to better adjust the tire's position, ensuring that the tire always remains in the center of the conveyor belt assembly 2. Furthermore, lifting the tire with the top roller 44 avoids problems such as poor tire movement or deviation caused by excessive friction or jamming between the tire and the conveyor belt assembly 2.

[0032] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a spacer device 5 is provided at the U-shaped frame 33. The spacer device 5 includes a geometric push rod 54 and two elastic telescopic rods 51. The fixed ends of the two elastic telescopic rods 51 are respectively fixed to the outer walls of the two U-shaped frames 33 located in the tire's forward direction. Each telescopic end of the two elastic telescopic rods 51 is fixed with a push plate 52. The push plate 52 is located in the tire's forward direction, and a fixing post 53 is fixed to the top of the push plate 52. The geometric push rod 54 is slidably installed on the top of the U-shaped frame 31. The top of the geometric push rod 54 is hinged to the outer wall of the horizontal plate 36 through a hinged telescopic rod 55. The bottom of the horizontal rods on both sides of the geometric push rod 54 is connected to the long groove plate 38. The tops of the two push rods are on the same horizontal plane. The fixed column 53 is located on the movement trajectory of the horizontal rods on both sides of the shaped push rod 54. The middle part of the shaped push rod 54 is set in an inverted U-shape. The inverted U-shape of the shaped push rod 54 is used to prevent the presence of the shaped push rod 54 from interfering with the operation of the U-shaped push rod 42. Through the above structure, the front tire is kept away from the two front return frames 33, thereby avoiding the problem that the conveyor belt group 2 will move the front tire between the two front return frames 33, which would hinder the swing of the return frame 33 and affect the function of the return frame 33 driving the contact roller 34 to adjust the tire. This ensures that the return frame 33 can swing freely and work according to the predetermined trajectory, thereby accurately centering the tire.

[0033] The U-shaped frame 31 is equipped with an anti-parallelism device 6 in the direction of tire movement. The anti-parallelism device 6 includes two F-shaped rods 61 fixed to the top of two long groove plates 38 respectively. T-shaped posts 63 are slidably installed on the side of the two F-shaped rods 61 that are far apart from each other. Clamping plates 62 are fixed on the side of the two T-shaped posts 63 that are close to each other. A spring is provided between the clamping plates 62 and the F-shaped rods 61. With the above structure, the clamping plates 62 will pre-clamp the multiple tires on the front side, thereby ensuring that they will not be misaligned or overlapped when pushed by the push plate 52.

[0034] During use, as the return frame 33 swings towards the center of the U-shaped frame 31, the return frame 33 drives the push plate 52 and the fixed column 53 to swing synchronously via the elastic telescopic rod 51. Simultaneously, the electric push rod 35 pushes the horizontal plate 36, which in turn drives the hinge rod 37 to pull the geometric push rod 54 along the top of the U-shaped frame 31. The geometric push rod 54 pushes the fixed column 53, causing the push plate 52 to move away from the return frame 33. The push plate 52 also causes the telescopic end of the elastic telescopic rod 51 to extend. At this time, the push plate 52 pushes the tire in front of the tire requiring centering to move away from the U-shaped frame 31. This keeps the front tire away from the two return frames 33 on the front side, thus preventing the conveyor belt group 2 from moving the front tire between the two return frames 33 on the front side, hindering the swing of the return frame 33 and affecting the function of the return frame 33 driving the contact roller 34 to adjust the tire. This ensures that the return frame 33 can swing freely and work along a predetermined trajectory, thereby accurately centering the tire.

[0035] It should be noted that since the middle part of the geometric push rod 54 is inverted U-shaped, the presence of the geometric push rod 54 will not interfere with the operation of the U-shaped push rod 42 during the process of the long slot plate 38 pushing the inverted trapezoidal inclined surface of the U-shaped push rod 42 to move the U-shaped push rod 42 upward.

[0036] During each movement of the long groove plate 38 along the top of the U-shaped frame 31 toward the center of the U-shaped frame 31, the long groove plate 38 drives the F-shaped rods 61 on both sides to move toward the center of the frame 1. The F-shaped rods 61 drive the clamping plate 62 to move along with them through the T-shaped column 63. The clamping plate 62 pre-clamps multiple tires on the front side, thereby ensuring that they will not be misaligned or overlapped under the push of the push plate 52. This can greatly improve the positioning accuracy of each tire during the transmission process and avoid the offset or misalignment caused by the parallel transmission of tires. This allows the tires to maintain the correct position in subsequent alignment operations. At the same time, the spring setting between the clamping plate 62 and the F-shaped rod 61 allows the clamping plate 62 to adaptively perform pre-clamping operations on tires of different sizes and specifications.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
