Description

[0001] This application is a divisional application of the invention patent application with the application date of July 30, 2024, application number 202411025936.X, and invention name “A Rotary Tire Gripper for a Tire Vulcanizer”. Technical Field

[0002] The invention relates to the technical field of tire vulcanizing equipment, and in particular to a rotary tire gripper for a tire vulcanizer. Background Art

[0003] At present, the sidewalls of tires on the market need to contain QR code features related to the tire. Therefore, when the tire is vulcanized, a vulcanization QR code needs to be pasted on the sidewall of the green tire.

[0004] Because some manufacturers have certain requirements for the position of the QR code, one QR code pasting method is that before the tire is vulcanized, the worker manually pastes the vulcanized QR code at a specific position in the vulcanizer; another QR code pasting method is that the worker pastes the vulcanized QR code on the green tire, and then the worker manually rotates the green tire to ensure that the vulcanized QR code is rotated to a specific position, but the accuracy of manually rotating the green tire is difficult to guarantee; and the above two QR code pasting methods have a relatively low degree of automation, low production efficiency, and certain safety hazards.

[0005] Therefore, it is an urgent problem to be solved at this stage to develop and design a tire vulcanizer rotary tire gripper that can automatically and accurately rotate the green tire to ensure that the QR code can be accurately vulcanized at a specific position on the side of the green tire. Summary of the invention

The barcode recognition component can be used to identify the position of the vulcanization QR code on the raw tire, and the second drive component can be used to drive the gripper disc to rotate relative to the tray to accurately control the rotation angle of the raw tire. When the rotation detection component measures that the raw tire has rotated to a suitable position, the raw tire can be placed in the vulcanizer for vulcanization, ensuring that the QR code can be accurately vulcanized at a specific position on the side of the raw tire, thereby realizing the automation and unattended operation of the entire vulcanization process, and can effectively reduce safety hazards and labor intensity.

[0064] Please refer to Figure 1-Figure 3 , the specific working process of the present invention is as follows:

[0065] After the vulcanized QR code is pasted on the green tire, the manipulator mounted on the mobile bracket drives the present invention to move to the top of the green tire with the vulcanized QR code pasted on it and then descends to a suitable tire grabbing position, so that a plurality of claws 21 extend into the green tire; before grabbing the tire, the toothed block 42 is located at the first position and the driving gear is in a braking state;

[0066] The first driving assembly 22 drives the plurality of claws 21 to synchronously move radially outward to grab the green tire, and the manipulator rises and moves to the top of the vulcanizer;

[0067] Since the position of the tire mold has been fixed before vulcanizing the tire, the position of the corresponding QR code in the tire mold is fixed, and the position information is input into the controller, the manipulator drives the green tire to move into the vulcanizer, the barcode recognition component 6 recognizes the position of the vulcanization QR code and feeds back to the controller, and the controller calculates the angle required for the green tire to rotate;

[0068] The toothed block 42 moves to the second position, the second driving assembly 35 drives the driving gear to rotate to rotate the placenta grabber 2, and the rotation detection assembly measures the rotation angle of the placenta grabber 2 in real time. When the rotation reaches a predetermined angle, the rotation stops, and the toothed block 42 moves to the first position to position the placenta grabber 2;

[0069] The first driving assembly 22 drives the plurality of claws 21 to retract radially inward synchronously, and the claws 21 close to put down the green tire, and the manipulator rises to move the present invention out of the vulcanizer, and the vulcanization process can begin.
