The patent application No. 10-2014-0174611 is a patent for the manner in which a tire is handled during attachment of the sealant composition.
A problem to be solved by the present invention is to provide a servo motor, a LM guide, a cylinder, and the like in comparison with a conventional method of setting coordinates using a robot, so that the overall structure is simple and durability is improved.
Another problem to be solved by the present invention is to make it possible to apply the present invention in a case where only the application width is set according to the tire standard change even though the coordinates of the inner surface profile of the tire are not known.
Another problem to be solved by the present invention is to improve the durability by reducing the possibility of failure due to the difference in the inner structure of the tire and the impact because the movement of the nozzle can be changed flexibly by the swivel and the spring.
The solution to the problem of the present invention comprises the steps of inputting the coating width and the coating speed of the sealant composition into the controller through the HMI, rotating the tire at a speed for attaching the sealant composition in a centered state, Entering the nozzle using a LM guide and a servo motor using a ball screw as a start position for attachment of the sealant composition; And a step of starting the adhesion of the sealant composition while contacting the inner surface of the tire by using a cylinder which causes the nozzle to move down while the fixed nozzle is released, as well as a method of applying the sealant composition to the inside of the tire.
A further object of the present invention is to provide a method and a device for solving the problems of the present invention, which comprises the step of returning to the nozzle origin by using a cylinder which raises and lowers the LM guide, the servo motor and the nozzle by using a ball screw when the attachment of the sealant composition is completed To provide a method of applying a sealant composition inside a tire.
A further object of the present invention is to provide a tire made by a method of applying a sealant composition to a tire according to the present invention.
1) Simplification of configuration
The configuration is simpler than the method of setting the coordinates using the robot.
The driving unit is composed of one servo motor, LM guide, cylinder, and so on.
2) Ease of application
It is possible to apply without knowing the inner surface profile coordinates of the tire.
Only the application width may be set and applied in accordance with the tire standard change.
3) Minimize problems
Since the swivel and spring can change the movement of the nozzle in a fluid way
There is little possibility of failure due to the difference in internal structure of the tire and shock.

Fig. 4 is a front view of the sealant-adhering surface. Fig.
5 is a side view of the sealant mounting surface.
Hereinafter, the present invention will be described in detail.
In the prior art, in order to attach the sealant to the tire, the inner surface coordinates of the tire are extracted and the nozzle is moved by using the robot and the robot controller to attach the sealant to the inner surface of the tire. However, Plane coordinates and precise control using a robot is necessary, which is a time and effort-intensive method.
The present invention minimizes unnecessary parts through the application of the servo motor and the improvement of the structure.

(4) Starting the adhesion of the sealant composition (Swivel joint method) while touching the inner surface of the tire using a cylinder that causes the nozzle to move down while the fixed nozzle is released (cylinder operation, nozzle down operation).
Since the movement of the nozzle can be changed flexibly by the swivel and the spring, there is an advantageous effect that the influence due to the difference in the internal structure of the tire and the possibility of failure due to the impact can be minimized.
(5) The step of bringing the nozzle into close contact with the tire surface by the spring.

(2) a cylinder that moves the nozzle up and down.
(3) a nozzle for adhering the sealant composition to the tire inner surface (inner surface).
- The nozzle end should be oriented vertically from the center of rotation to the tire application surface to prevent line spacing deformation during rotation during rotation.
(4) Includes a nozzle block that connects the nozzle to the supply hose and determines supply / stop.
The terms necessary for understanding the present invention will be summarized.
The sealant composition refers to a material that is applied or coated on the inner surface to prevent puncture of the tire.
The inner surface of the tire refers to the rubber surface constituting the inside of the tire to maintain the air pressure of the tire.
The nozzle refers to a mechanism by which the sealant composition is discharged to apply the sealant composition to the inner (inner) surface of the tire.
The center line refers to the tire center line when viewed from the tire tread surface.
As shown in Fig. 5, in the present invention, even if the height of the tire attaching surface (inner surface) changes, the distance between the attaching seals remains constant.
The method includes the steps of inputting a sealant application width and an application speed to the controller through an HMI, rotating the sealant composition at a rate for attaching the sealant composition in a centered state by providing a tire in the apparatus for attaching the sealant composition, The method includes the steps of entering a nozzle using an LM guide and a servo motor using a ball screw as a start position, and moving the nozzle in a downward direction by using a cylinder that moves the nozzle downward (a cylinder operation and a nozzle down operation) (Swivel joint method), the method of applying the sealant composition to the inner surface of the tire including the step of attaching the sealant composition to the tire manufactured by the manufacturing method, thereby lowering the manufacturing cost of the tire, Very high.
