Abstract
Description
Technical Field
[0001] This application belongs to the technical field of tire centering equipment, and specifically relates to a tire position correction device. Background Technology
[0002] As the only component in contact with the ground in vehicles such as motor vehicles and airplanes, tires play a crucial role in providing support, transmitting power and braking force, cushioning and filtering road vibrations, and ensuring driving safety and comfort. The structural integrity of the tire is key to ensuring these functions. Therefore, tires require various processes, such as rigorous visual inspection after production, marking and printing, and during tire repair, tread pattern restoration and sidewall seam trimming. These tasks are all aimed at ensuring the tire's structural integrity and proper functioning. Currently, the equipment used for these operations urgently needs automation improvements to enhance efficiency. Examples include machine vision inspection equipment for tire appearance checks, sidewall barcode scanners for acquiring tire data before inspection, and equipment for tire trimming and restoration. Since these systems operate within specific areas and ranges, they require precise delivery of tires to designated workstations.
[0003] Current technology primarily uses roller conveyors to transport tires. While this improves transport efficiency, it still suffers from inaccurate tire positioning. Tires are manually moved to the conveyor's end, and then transported to the designated workstation according to a set speed and distance. However, manual tire placement can lead to deviations, causing the tire to veer off-center in various directions (front, back, left, right), resulting in the tire being transported past or before reaching its designated workstation. In such cases, the operator still needs to manually move the tire to the precise workstation, reducing transport efficiency and wasting manpower. Utility Model Content

The plurality of conveying rollers are spaced apart to form a conveying channel, and a tire positioning area is provided within the conveying channel. The tire positioning assembly includes a tire positioning unit and a drive unit. The tire positioning unit is disposed on at least one side of the conveying channel and is electrically connected to the drive unit. The drive unit is synchronously driven by the conveying rollers and is used to drive the conveying rollers to rotate forward or backward. The tire centering assembly includes four clamping arms.

The two ends of a plurality of conveying rollers are rotatably connected to a roller frame, and a second transmission wheel is fitted on the same end of each conveying roller. The first transmission wheel is coaxially connected to any one of the conveying rollers. The second transmission wheels are synchronously driven and cooperate with the second transmission component. The output shaft of the drive motor is driven and cooperates with the first transmission wheel through the first transmission component. The controller is electrically connected to the drive motor and the tire positioning unit. The controller is used to make the output shaft of the drive motor rotate in the forward or reverse direction.
[0007] Preferably, the tire positioning unit includes at least one position sensor, which is distributed along the tire conveying direction on at least one side of the conveying channel.
[0008] Preferably, the position sensor includes any one of a machine vision sensor, a contact sensor, or a non-contact sensor.
[0009] Preferably, the position sensor is a detection light curtain, which is used to detect tires on the conveyor, and the detection range of the detection light curtain can at least cover the tire positioning area along the tire conveying direction.
[0010] Preferably, the tire centering assembly further includes a base and a drive mechanism. The base is disposed below the conveyor channel relative to the tire positioning area. A first guide rail and a second guide rail are disposed on the top of the base parallel to the gap between the conveyor rollers. The clamping arms are all perpendicular to the top of the base, and one pair of clamping arms can slide along the first guide rail, while the other pair of clamping arms can slide along the second guide rail. The drive mechanism includes at least one drive member, which is disposed on one side of the base and is convexly connected to at least one of the four clamping arms. The drive member is used to drive the clamping arms to slide along the first guide rail or the second guide rail to clamp and center the tire between the clamping arms.
[0011] Preferably, there are two second guide rails, which are spaced apart on one side of the first guide rail. The lower end of the clamping arm is provided with a sliding seat, one pair of which slides with the first guide rail, and the other pair slides with the two second guide rails. The driving mechanism further includes a transmission belt, at least four first guide wheels, at least four second guide wheels, and two third guide wheels. The third guide wheels are located at opposite ends of the second guide rails and are rotatably connected to the base. The first guide wheels are correspondingly located at both ends of the first guide rail and at the opposite ends of the second guide rails and are rotatably connected to the base. The second guide wheels are symmetrically distributed between the first and second guide rails and are rotatably connected to the base. Both ends of the transmission belt are respectively sleeved with the third guide wheels, and the sides of the first guide wheels are in contact with the inner side of the transmission belt. The sides of the second guide wheels are in contact with the outer side of the transmission belt. At least one side of each sliding seat is fixedly connected to the transmission belt.

[0014] Preferably, the clamping arm is rotatable about its axis.
[0015] By adopting the above technical solution, compared with the prior art, this application has at least the following beneficial effects: Tires are placed at the beginning of the conveyor. The drive unit first drives the conveyor rollers to rotate synchronously in the forward direction according to a set procedure, conveying the tire backward at a set distance. If, due to a feeding error, the tire is placed outside the feeding area, but the conveyor continues to convey the tire at the set distance, preventing the tire from being effectively transported to the tire positioning area, the tire positioning unit can obtain the actual position of the tire and cause the drive unit to drive the conveyor rollers to rotate in the reverse direction, transporting the tire to the tire positioning area. Then, the tire centering component centers the tire, thereby correcting the tire conveying deviation. The entire tire position correction process is performed automatically through the above steps, improving tire transport efficiency and positioning accuracy, while saving manpower.

The technical solutions of this application will be further described below with reference to the accompanying drawings of the embodiments, and this application is not limited to the following specific implementation methods.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limitations on this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present application will be further described in detail with reference to specific embodiments.
[0026] This application discloses a tire position correction device (hereinafter referred to as the "correction device"), see attached. Figure 1 The correction device includes several conveyor rollers 11, a tire positioning assembly 20, and a tire centering assembly 30. The conveyor rollers 11 are spaced apart to form a conveyor channel, which transports the tire under the rolling action of the conveyor rollers 11. At least one tire positioning area 12 is provided within the conveyor channel. In one embodiment, the tire positioning area 12 is located in the middle section of the conveyor channel. Inside or around this area, machine vision inspection equipment for tire appearance inspection, tire sidewall scanning equipment for acquiring tire data, or equipment for tire trimming and restoration can be installed to process the tire centered in the tire positioning area 12 accordingly.
[0027] The tire positioning assembly 20 includes a tire positioning unit 21 and a drive unit 22. The tire positioning unit 21 is disposed on one side of the tire positioning area 12 and electrically connected to the drive unit 22. During the tire's transport by the conveyor belt, the tire positioning unit 21 is used to obtain the tire's position relative to the tire positioning area 12. The drive unit 22 is synchronously driven by the conveyor roller 11 and can drive the conveyor roller 11 to rotate forward or backward, thereby transporting the tire into the tire positioning area 12. The tire centering assembly 30 includes four clamping arms 33. Within the tire positioning area 12, one pair of the four clamping arms 33 is located in the gap between two adjacent conveyor rollers 11, and another pair of clamping arms 33 is located in the gap between the other two adjacent conveyor rollers 11. All clamping arms 33 can slide along the gap between the conveyor rollers 11. When the four clamping arms 33 slide toward the central axis of the conveyor belt, they can center the tire that is off-center from the central axis of the conveyor belt, clamping and confining the tire to the center position of the tire positioning area 12.
[0028] Specifically, the first end of the aforementioned conveyor is designated as the tire loading area. The length of this loading area and the length of the tire positioning area 12 (the length along the conveyor in the tire conveying direction) are both set to be no greater than the tire's diameter. The conveying speed of the conveyor is set to a constant value. When the tire is precisely placed within the loading area, the conveyor can transport the tire to the tire positioning area 12 at a set distance, enabling the machine vision inspection equipment, sidewall scanning equipment, or tire trimming and restoration equipment installed within the tire positioning area 12 to perform precise corresponding operations on the tire. If the tire is not placed in the center of the loading area and is placed further back, or if the tire's axis deviates from the central axis of the conveyor, the tire will completely or partially exceed the tire positioning area 12 when it stops. In this case, the tire positioning unit 21 obtains the tire's position relative to the tire positioning area 12, and the drive unit 22 reverses the drive roller 11 to transport the tire back to the tire positioning area 12. Finally, the tire centering component 30 centers and clamps the tire, ensuring that the tire's axis is aligned with the center of the tire positioning area 12.
[0029] Using this tire position correction device provides at least the following benefits: Tires are placed at the beginning of the conveyor belt. The drive unit 22 first drives the conveyor roller 11 to rotate synchronously in the forward direction according to a set procedure, conveying the tire backward at a set distance. If, due to a feeding error, the tire is placed outside the feeding area, but the conveyor belt continues to convey the tire at the set distance, preventing the tire from being effectively transported to the tire positioning area 12, the tire positioning unit 21 can obtain the actual position of the tire and cause the drive unit 22 to drive the conveyor roller 11 to rotate in the reverse direction, transporting the tire into the tire positioning area 12. Then, the tire centering component 30 centers the tire. The entire tire position correction process is performed automatically through the above steps, improving tire transportation efficiency and positioning accuracy while saving manpower.
[0030] Based on the above embodiments, this application also provides some specific implementation methods to improve the above solutions.
[0031] In one preferred embodiment, see Appendix Figure 2The aforementioned drive unit 22 includes a drive motor 221, a controller 222, a first transmission component 223, a second transmission component 224, and a first transmission wheel 225. Both ends of the conveying roller 11 are rotatably connected to the roller frame 13 of the roller conveyor body, allowing the conveying roller 11 to roll relative to the roller frame 13. A second transmission wheel 111 is fitted onto the same end of each conveying roller 11. Specifically, in this embodiment, both the first transmission wheel 225 and the second transmission wheel 111 are preferably gears, and both the first transmission component 223 and the second transmission component 224 are preferably chains. The first transmission wheel 225 is coaxially connected to any one of the several conveying rollers 11, meaning that second transmission wheels 111 are spaced apart at the same end of this conveying roller 11. The second transmission component 224 is a chain longer than the first transmission component 223, and the second transmission component 224 meshes with all the second transmission wheels 111 to achieve the conveying of all conveying components. Roller 11 can be synchronously driven; the housing of drive motor 221 is fixed to one side of roller frame 13, and one end of the output shaft of drive motor 221 is also provided with a gear, which is synchronously driven with first transmission wheel 225 through first transmission component 223; controller 222 is electrically connected to drive motor 221 and tire positioning unit 21. Specifically, the drive motor 221 is either a DC motor or an AC induction motor, and controller 222 is a professional device adapted to any of the above motors to control the motor rotation direction and working time. The receiving end of controller 222 is connected to tire positioning unit 21, and the transmitting end of controller 222 is connected to drive motor 221. Controller 222 can receive the signal from tire positioning unit 21 that the tire has exceeded tire positioning unit 21 and cause drive motor 221 to rotate in the opposite direction, so that the conveyor transports the tire in the opposite direction to the tire positioning area 12.
[0032] When a tire is placed arbitrarily and exceeds the tire positioning area 12, the tire positioning unit 21 includes at least one position sensor to obtain tire position information. This position sensor is distributed along the tire conveying direction on at least one side of the conveyor belt, and acquires the tire's position relative to the tire positioning area 12 in real time. Specifically, the position sensor is preferably any one of a machine vision sensor, a contact sensor, or a non-contact sensor. Different numbers and types of position sensors can acquire tire position information in different ways. The technology by which the tire positioning unit 21 acquires tire position information is well-known to those skilled in the art. This application briefly describes this using the following embodiments. In one embodiment, the position sensor is preferably a non-contact sensor, such as a detection light curtain. This detection light curtain is disposed along the tire conveying direction on at least one side of the conveyor belt. The detection light curtain is used to detect tires on the conveyor belt in real time, and its detection range can at least cover the tire positioning area 12 along the tire conveying direction. The detection light curtain can sense the tire's position in real time. If the tire has not reached the tire positioning area 12, the conveyor roller 11 will rotate clockwise or counterclockwise to transport the tire into the tire positioning area 12. Alternatively, it can only acquire the tire's position relative to the tire positioning area 12. When the tire fully enters the tire positioning area 12, the conveyor roller 11 will stop rotating simultaneously to ensure that the tire stops within the tire positioning area 12. Other embodiments are merely corresponding changes made to the selection of position sensors, and will not be described in detail in this application.
[0033] Furthermore, to ensure that the tire's axle is located at the center of the tire positioning area 12, in a preferred embodiment, see attached... Figure 3 The aforementioned tire centering assembly 30 further includes a base 31 and a drive mechanism 32. The base 31 is positioned below the conveyor channel relative to the tire positioning area 12. At least one first guide rail 311 and at least one second guide rail 312 are provided on the top of the base 31, corresponding to the gap between two adjacent conveying rollers 11, and the first guide rail 311 and the second guide rail 312 are parallel to each other. In one embodiment, all four clamping arms 33 are perpendicular to the top of the base 31, and one pair of clamping arms 33 can slide along the first guide rail 311, while the other pair of clamping arms 33 can slide along the second guide rail 312. Specifically, the lower ends of the clamping arms 33 are respectively provided with sliding seats 313. One pair of sliding seats 313 is slidably disposed on the first guide rail 311, and another pair of sliding seats 313 is slidably disposed on the second guide rail 312. The sliding seats 313 can slide along the first guide rail 311 and the second guide rail 312, respectively.
[0034] Furthermore, the drive mechanism 32 includes at least one drive element 321, which is one of a drive device capable of outputting power in a straight line, such as a drive cylinder, an electric telescopic cylinder, or an electric push rod. Specifically, the drive element 321 is disposed on one side of the base 31, and the sliding seat 313 is transformably connected to the output end of the drive element 321. The drive element 321 can drive the sliding seats 313 on the first guide rail 311 and the second guide rail 312 to converge towards the central axis of the conveying channel, so that the four clamping arms 33 can center the tire. In the above embodiment, the number of drive elements 321 can be one, two, or four. When there are one or two drive elements 321, the drive elements 321 need to achieve synchronous transmission and cooperation with the four clamping arms 33 through a transmission mechanism to achieve synchronous movement of the clamping arms 33; when there are four drive elements 321, the four drive elements 321 can drive each clamping arm 33 to center the tire.
[0035] Furthermore, in order to enable the gripping arms 33 to move synchronously and achieve precise centering, in one embodiment, see Appendix Figure 5 The aforementioned second guide rail 312 consists of two rails, each with a length not exceeding half the length of the first guide rail 311. The two second guide rails 312 are spaced apart on one side of the first guide rail 311 and symmetrically distributed relative to the central axis of the conveyor. In this embodiment, the base 31 includes three spaced base plates, two of which are shorter and symmetrically distributed relative to the central axis of the conveyor. The longer base plate is fixed below the conveyor parallel to the shorter base plates. The two second guide rails 312 are respectively disposed on the top of the two shorter base plates, and the first guide rail 311 is disposed on the top of the longer base plate. The first guide rail 311 is disposed in one of the four sliding seats 313 at the lower end of the four clamping arms 33. One pair of sliding seats 313 is slidably connected to two of the second guide rails 312, and the other pair is slidably connected to the first guide rail 311.
[0036] In addition, the aforementioned drive mechanism 32 also includes a transmission belt 322, at least four first guide pulleys 323, at least four second guide pulleys 324, and two third guide pulleys 325. Preferably, in this embodiment, there are four first guide pulleys 323 and four second guide pulleys 324. The two third guide pulleys 325 are located at opposite ends of the two second guide rails 312 and are rotatably connected to the base 31. The two first guide pulleys 323 are located at both ends of the first guide rails 311 and are rotatably connected to the base 31. The other two first guide pulleys 323 are located at opposite ends of the two second guide rails 312 and are rotatably connected to the base 31. The four second guide pulleys 324 are symmetrically distributed between opposite sides of the first guide rails 311 and the second guide rails 312 and are rotatably connected to the base 31. The rectangle formed by the lines connecting the four second guide pulleys 324 is located within the rectangle formed by the lines connecting the four first guide pulleys 323. The transmission belt 322 is loop-shaped. Both ends of the transmission belt 322 are respectively sleeved with the third guide pulley 325, and the side of the first guide pulley 323 is in frictional contact with the inner surface of the transmission belt 322; the side of the second guide pulley 324 is in frictional contact with the outer surface of the transmission belt 322, so that the transmission belt 322 is subjected to tension at the first guide pulley 323, the second guide pulley 324 and the third guide pulley 325.
[0037] Furthermore, the two pairs of sliding seats 313 on the first guide rail 311 are respectively fixedly connected to the transmission belt 322 on opposite sides; the other pair of sliding seats 313 on the second guide rail 312 are respectively fixedly connected to the transmission belt 322 on opposite sides; the output end of the drive member 321 is fixedly connected to any one of the sliding seats 313. In this embodiment, see the attached drawing. Figure 4 On the first guide rail 311, a limiting clip 3131 is fixed to the lower side of the left sliding seat 313. The limiting clip 3131 can clamp the portion of the transmission belt 322 near the lower side of the first guide rail 311. A limiting clip 3131 is fixed to the upper side of the right sliding seat 313. The limiting clip 3131 can clamp the portion of the transmission belt 322 near the upper side of the first guide rail 311. In addition, on the second guide rail 312, a limiting clip 3131 is fixed to the lower side of the left sliding seat 313. The limiting clip 3131 can clamp the portion of the transmission belt 322 near the lower side of the second guide rail 312. A limiting clip 3131 is fixed to the upper side of the right sliding seat 313. The limiting clip 3131 can clamp the portion of the transmission belt 322 near the upper side of the second guide rail 312, thereby fixing the transmission belt 322 to each sliding seat 313. The aforementioned driving component 321 is an electric telescopic cylinder or a pneumatic cylinder. The driving component 321 is parallel to the first guide rail 311 and distributed on one side of the first guide rail 311. One end of the output shaft of the driving component 321 is fixedly connected to the sliding seat 313 on the left side of the first guide rail 311 through a connecting rod 314.
[0038] When using the tire centering assembly 30 of this embodiment, the initial position of the sliding seat 313 is located at both ends of the first guide rail 311 and at one end of the second guide rail 312 that is separate from it, and the initial state of the output shaft of the drive member 321 is the extended state. When the output shaft of the drive unit 321 retracts, it causes the sliding seat 313 on the left side of the first guide rail 311 to move to the right. The sliding seat 313 causes the portion of the transmission belt 322 near the lower side of the first guide rail 311 to move to the right. Under the guidance of the first guide wheel 323, the portion of the transmission belt 322 near the upper side of the first guide rail 311 moves to the left, causing the sliding seat 313 on the right side of the first guide rail 311 to move to the left. At the same time, the portion of the transmission belt 322 near the lower side of the second guide rail 312 moves to the right under the guidance of the third guide wheel 325, causing the sliding seat 313 on the left side of the second guide rail 312 to move to the right. Similarly, the portion of the transmission belt 322 near the upper side of the right side of the second guide rail 312 moves to the left under the guidance of the third guide wheel 325 and the second guide wheel 324, causing the sliding seat 313 on the right side of the second guide rail 312 to move to the left. This causes the two clamping arms 33 on the left and the two clamping arms 33 on the right of the conveyor channel to converge synchronously towards the center axis of the conveyor channel, thereby achieving precise centering of the tire.
[0039] Furthermore, the aforementioned drive component 321 is preferably selected from any one of a drive cylinder, an electric telescopic cylinder, and a servo electric cylinder. For example, for a drive cylinder, see the appendix. Figure 3 In one embodiment, the drive cylinder is parallel to the first guide rail 311 and is disposed on one side of the first guide rail 311, and its output shaft is fixedly connected to any sliding seat 313 on the first guide rail 311 via a connecting rod 314; in another embodiment, the drive cylinder is located on one side of any second guide rail 312, and its output shaft is fixedly connected to any sliding seat 313 on the second guide rail 312 via a connecting rod 314.
[0040] Furthermore, to ensure the output shaft of the aforementioned drive cylinder always moves in a straight line and to guarantee the stability of the driven sliding seat 313, the base 31 is provided with several guide seats 315 spaced apart along the side of the first guide rail 311 away from the second guide rail 312. Each guide seat 315 has a guide hole 3151 extending through it, with the axial direction of the guide holes 3151 parallel to the first guide rail 311. The output shaft of the drive cylinder passes through the guide hole 3151 and is slidably connected to it. The guide seats 315 restrict and guide the movement of the output shaft, effectively preventing deformation or bending of the output shaft due to the reaction force from the sliding seat 313 on one side during frequent extension and retraction. This ensures that the sliding seat 313 can be stably pushed by the drive cylinder, extending the service life of all moving parts.
[0041] Furthermore, to reduce tire tread wear caused by relative sliding between the tire and the clamping arm 33 during tire clamping, the clamping arm 33 is rotatable around its axis. In one embodiment, the clamping arm 33 includes a support shaft 331 and a centering roller 332. The lower end of the support shaft 331 is fixedly connected to the sliding seat 313, and the centering roller 332 is sleeved on the support shaft 331 and rotatably engages with it. During the contact of the clamping arm 33 with the tire, the rotatable centering roller 332 not only reduces the probability of frictional damage to the tire tread but also dynamically guides the tire that is slightly off-center from the centerline of the conveyor.
[0042] Based on the aforementioned tire position correction device, the following effects can be achieved: the tire positioning component 20 accurately transports the tire to the tire positioning area 12 via the conveyor belt, thus solving the problem of the tire deviating from the center of the conveyor end due to manual tire placement; furthermore, the tire centering component 30 precisely centers the tire, ensuring that the tire's center is at the center of the tire positioning area 12, thus solving the problem of the tire deviating to the left or right from the center of the conveyor end due to manual tire placement. This position correction device has a reasonable layout and is suitable for converting existing roller conveyors into automated tire inspection lines. It can be applied to equipment for automatic tire inspection and automatic trimming.
[0043] Obviously, the above embodiments of this application are merely examples for clearly illustrating this application, and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
