Description

Technical Field

[0001] This utility model belongs to the field of tire assembly technology, and in particular relates to a tire flipping mechanism. Background Technology

[0002] Tires often need to be flipped during production, storage, transportation, and maintenance to complete operations such as inspection, assembly, and stacking. Traditional methods mostly rely on manual labor or simple tools for flipping. For large tires, especially heavy truck and engineering vehicle tires, due to their large weight and varying sizes, manual flipping is not only labor-intensive and inefficient, but also prone to tire damage or personnel accidents due to improper operation. Some existing mechanical flipping devices have poor adaptability, making it difficult to be compatible with different tire specifications, or have low automation levels that require manual assistance for positioning. They cannot meet the needs of modern production lines and logistics systems for efficient, safe, and intelligent flipping operations. Therefore, it is necessary to develop a tire flipping mechanism that is highly adaptable and automated, and can ensure the accurate installation posture of multiple tire models, effectively improving production efficiency.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figure 1 As shown, the tire flipping mechanism includes a flipping device 1, which is installed on the side where the tire is transported out from the previous process. The flipping device 1 is used to flip the tire. The flipping device 1 is equipped with a conveying device 2, a pressing device 3, and a guiding device 4. The conveying device 2 is used to transport the tire before and after flipping. The pressing device 3 is used to press and fix the tire. The guiding device 4 is used to guide the linear movement trajectory of the tire in the conveying device 2. When the tire enters the conveying device 2 from the previous process, the pressing device 3 extends and presses on the upper end of the tire to fix the tire. After the tire is fixed, the flipping device 1 flips 180°. After flipping, the pressing device 3 retracts and puts the tire back onto the conveying device 2. After being put back, the conveying device 2 transports the tire to the subsequent device.

[0035] like Figure 2As shown, the flipping device 1 includes a support 11, a frame 12, a first drive unit 13, and a rotating shaft 14. The two sides of the frame 12 are rotatably connected to the support 11 via a rotating shaft 14. The first drive unit 13 is mounted on the support 11 and drives the frame 12 to rotate. The first drive unit 13 is a combination of a conventional rotary motor and a reducer. The rotary motor is model CM3C63S, and the reducer is model KF77R37. When the controller is turned on, it drives the first drive unit 13 to rotate, which in turn drives the rotating shaft 14 to rotate, thereby controlling the overall flipping of the flipping device 1. This device can flip tires, ensuring the stability of the tire installation posture, guaranteeing the accuracy of tire installation, promoting the continuous progress of the tire installation process, improving work efficiency, and replacing manual labor, thus reducing labor costs.

[0036] like Figure 3 As shown, the conveying device includes two sets of axially symmetrically arranged conveying assemblies. The conveying device 2 includes two sets of opposing conveying assemblies 21. One set of conveying assemblies 21 is located at the lower end inside the frame 12, and the other set of conveying assemblies 21 is located at the upper end inside the frame 12. Figure 4 As shown, the conveying assembly 21 includes an active unit 211, a driven unit 212, a connecting rod 213, and a second drive unit 214. The active unit 211 and the driven unit 212 are arranged in parallel to each other. The active unit 211 and the driven unit 212 form a synchronous transmission structure through the connecting rod 213. The second drive unit 214 is installed on one side of the active unit 211 and is used to drive the active unit 211.

[0037] like Figure 4-6As shown, the active unit 211 and the driven unit 212 have the same structure. The active unit 211 includes a roller frame 2111, rollers 2112, a driving sprocket 2113, a chain 2114, and driven sprockets 2115. The roller frame 2111 is installed inside the frame 12. Multiple rollers 2112 are sequentially rotatably connected to the roller frame 2111 along the tire's travel direction. One end of each roller 2112 and both ends of the connecting rod 213 are respectively fitted with a driven sprocket 2115. The driving sprocket 2113 is rotatably mounted on an inner side wall of the roller frame 2111. Each driven sprocket 2115 and the driving chain 2114 are connected to the driving chain 2115. All wheels 2113 are meshed with chains 2114. The drive sprocket 2113 is fixedly connected to the output end of the second drive unit 214. The second drive unit 214 is a servo motor of the prior art, model KF29DRN80MK4BE1. The controller controls the servo motor of the drive unit 211 to rotate, driving the drive sprocket 2113 to rotate. Under the action of the chain 2114, the roller 2112 also rotates. The rotating roller 2112 can transport the tires that are rolled on it, and can also drive the driven unit 212 on the other side to transport tires through the connecting rod 213. A conveying device 2 is provided, which can transport tires into the tire flipping mechanism, and can continue to transport the tires to the next process after flipping, ensuring the continuous operation of the production process.

[0038] like Figure 7 As shown, the clamping device 3 includes two sets of telescopic units 31 arranged parallel to each other. Each telescopic unit 31 includes a telescopic cylinder 311 and a pressure plate 312. The telescopic cylinder 311 is fixedly installed on the upper end of the frame 12. The movable end of the telescopic cylinder 311 is connected to the pressure plate 312. The fixed end of the telescopic cylinder 311 is installed on the upper end inside the frame 12. The telescopic cylinder 311 is existing technology, and its model is MDB63-175Z. When the tire reaches the predetermined position, the controller controls the telescopic cylinder 311 to extend and push the pressure plate 312 to abut against the upper end of the tire, fixing the tire. After flipping, the cylinder retracts, placing the tire on another set of conveying components 21 for subsequent processes. The clamping device 3 can clamp and fix the tire, and after the tire is flipped, it is placed back on the conveying device 2, ensuring that the tire is stable and does not detach during the flipping process, reducing safety risks.

[0039] like Figure 8 As shown, the guiding device 4 includes two sets of opposing guiding units 41. Each set of guiding units 41 includes a roller frame 411 and multiple rollers 412. The roller frame 411 is provided on the side wall inside the frame 12. Multiple rollers 412 are arranged in sequence along the tire travel direction inside the roller frame 411. The outer periphery of the rollers 412 is connected to the tire tread. During the movement of the tire, the tire tread rolls along the direction of the rollers 412 to limit the movement trajectory of the tire.

[0040] like Figure 9 As shown, a photoelectric sensor 5 is also installed inside the frame 12. The photoelectric sensor 5 is mounted on the upper end of the roller frame 2111. The photoelectric sensor 5 is used to detect the presence of the tire. The photoelectric sensor 5 is existing technology, and its model number is GL6-P7112. When the tire is on the conveyor 2, the photoelectric sensor 5 detects that the tire has been transported to the position requiring rotation and sends a signal to the controller. The controller then receives the command and performs subsequent actions. The installation of the photoelectric sensor 5, which can determine the tire's position, ensures the accuracy of the tire's posture and allows for real-time feedback of information to the controller, ensuring the continuity of the process.

[0041] The working process of the tire tipping mechanism:

[0042] The tire enters the conveying device 2 from the previous process, and the direction of the tire's movement is controlled by the guide units 41 on both sides. The controller controls the conveying assembly 21 to transport the tire. After the photoelectric sensor 5 detects that the tire has reached the predetermined position, it stops transporting the tire, controls the pressing device 3 to extend and press on the upper end of the tire, fixes the tire, and then the flipping device 1 flips 180°. After flipping the tire, the pressing device 3 retracts and places the tire on another set of conveying assemblies 21. After being placed back, the other set of conveying assemblies 21 continues to transport the tire to the subsequent mechanism.

[0043] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
