Description

TECHNICAL FIELD [0001] The present invention relates to a coating system for liquefying a sealing liquid,

The present invention relates to a coating system for forming an application layer (L) for preventing puncture of a tire inside a tire.

More particularly, the present invention relates to a method of spraying a sealing liquid on an inner wall of a tire while rotating a tire, thereby uniformly maintaining the thickness of the coating layer (L) applied by the applied sealing liquid along the circumferential direction of the tire, This is a technology relating to a coating system capable of precisely controlling the temperature and the injection amount to a predetermined target value.

Generally, a tire filled with air is used for a motorcycle or a driving wheel of an automobile to maintain a proper air pressure.

Therefore, it is very important to prevent the puncture of a tire because it causes a large traffic accident if a puncture occurs in a tire when driving at a high speed.

Drivers of motorcycles and automobiles usually choose to periodically check the air pressure to prevent tire punctures, or to replace the tire on time according to the wear of the tire.

However, even if the tire is managed on a regular basis, if foreign matter (such as nails or glass fragments) fallen on the road penetrates through the tire, the air gradually leaks through the gap between the foreign substances and the air pressure of the tire drops. If you do not recognize it immediately, if you do not recognize it immediately, the pressure of the tire will drop and the tire will break the balance with the other wheels. As a result, the durability of the tire itself may end up causing a sudden puncture during running.

In order to overcome this problem, the sealing liquid is applied to the inner wall of the tire to allow the seal liquid to be applied around the clearance of the tire even when the foreign substance penetrates through the tire or the foreign substance is taken out again from the tire. And the like.

Since the sealing liquid applied to the inner wall of the tire is not in a solid solid state but is reacted amorphously with foreign substances penetrating through the tire to prevent air from entering and leaving the gap, Or gel state.

In addition, since the sealing liquid is a liquid in the process of applying the sealing liquid to the inner wall of the tire, it is very difficult to apply the sealing liquid uniformly to the inner wall of the tire. Thus, the sealing liquid applied to the inner wall of the tire, The curing of the sol (s) or gel (s) while maintaining the layer (L) requires very sophisticated working techniques.

The heating temperature control unit 710 controls the temperature of the heating furnace 100 to a preset temperature .

The heating temperature control unit 710 is operated by a user operation of a button corresponding to the heating temperature control unit 710 among the buttons provided on the front surface of the control box 30. [ In addition, when the button corresponding to the heating temperature control unit 710 is operated, a display unit for displaying a numerical value of the set temperature and a temperature value of the present heating furnace 100 at the upper part of the button so that the user can intuitively confirm the numerical value, .

Here, the sealing liquid injected into the heating furnace 100 is preferably made of a polyamide series, and a solvent-based emulsifier can be mixed so that the liquid sealing liquid can be smoothly injected. Further, the sealing liquid injected into the inner wall of the tire 20 And then the cyanoacrylic type chemical can be mixed so as to cure in a sol or gel state in a short time.

The injection nozzle unit 200 communicates with the heating furnace 100 and is disposed at a position adjacent to the heating furnace 100 and injects the sealing liquid heated through the heating furnace 100 to the inside of the tire 20. The injection nozzle unit 200 is configured to inject a predetermined injection amount under the control of the injection control module 600 mounted on the control box 30.

In detail, the injection control valve 610 adjusts the amount of the sealing liquid flowing through the liquid discharge pipe portion 300 according to the control operation of the injection control module 600 to accurately measure the injection amount per second through the injection nozzle portion 200 Can be controlled.

Meanwhile, the temperature of the sealing liquid injected through the injection nozzle unit 200 can be adjusted. The temperature control module 700 mounted on the control box 30 includes a nozzle temperature control unit 720, It is possible to control the temperature of the sealing liquid injected through the injection nozzle unit 200 to a preset temperature through the first nozzle 720.

In detail, when the nozzle temperature control unit 720 mounted on the temperature control module 700 operates at a second predetermined target temperature (for example, 170 ° C to 180 ° C), the temperature control unit 720, which is disposed adjacent to the injection nozzle unit 200, The temperature of the injection nozzle unit 200 is lowered to the second target temperature so that the high-temperature sealing liquid passing through the liquid discharge pipe unit 300 is lowered to the second target temperature and injected.

That is, as the nozzle temperature control unit 720 lowers the temperature of the injection nozzle unit 200, the temperature of the sealing liquid in the injection nozzle unit 200 is lowered and the actual temperature of the sealing liquid sprayed through the injection nozzle unit 200 .

The liquid discharge pipe unit 300 connects the injection nozzle unit 200 and the heating furnace 100 to transfer the heated sealing liquid through the heating furnace 100 to the injection nozzle unit 200.

The injection guide portion 400 aligns the tire 20 so that the open central portion of the tire 20 is positioned at the injection nozzle portion 200. The injection guide unit 400 aligns the tire 20 rotated by the rotation unit 500 so as to maintain a raised state and is preferably connected to the fixing bar 410 and the fixing bar 410 And a rotating bar 420 that rotates and rotates.

Specifically, the fixing bar 410 is formed in a bar shape and is disposed side by side with the in-place rotating part 500. Each of the pivoting bars 420 is pivotally coupled to the fixed bar 410 so that one end of the pivoting bar 420 is rotatably fitted to the fixed bar 410 410 are rotated by a predetermined angle and are mounted on the rotary unit 500 in a standing state to abut against both side walls of the rotating tire 20 to align and align the tire 20.

The in-place rotation unit 500 causes the tire 20, which is in an aligned state by the injection guide unit 400, to rotate in a circumferential direction at a predetermined position in the process of injecting the sealing liquid through the injection nozzle unit 200.

The in-place rotating part 500 is configured to rotate in a state where both ends are fixed on the upper surface of the base 10, and a pair of rotating bars are arranged to be spaced apart from each other by a predetermined distance so as to rotate in a state supporting the lower part of the tire 20 Do.

On the other hand, it is preferable that the in-place rotary part 500 controls the rotation drive motor 810 to rotate at about 2700 rpm in about 2,500.

When the coating layer L is formed on the inner side of the tire 20 in the state where the rotation of the in-place rotating part 500 is 2500 rpm or less, there is a problem that the surface of the coating layer L is not smooth, When the coating layer L is formed inside the tire 20 with the rotation of 2700 rpm or more, the sealing liquid injected through the injection nozzle unit 200 is injected into the side wall of the tire 20, A problem arises in which the film is formed to be deflected.

On the other hand, the tire 20 may be rotated in a state in which the tire 20 is laid down in the process of applying the sealing liquid to the inside of the tire 20. However, it is preferable to rotate the tire 20 upright in the process of applying the sealing liquid to the inside of the tire 20 as shown in Fig. 1 and Fig. The coating layer L formed on the inner wall of the tire 20 is automatically formed so as to maintain the balance between the left and right at the inner wall of the tire 20. [

The injection control valve 610 is mounted on the liquid discharge pipe unit 300 and serves to actually adjust the injection amount through the injection nozzle unit 200.

The blowing unit 900 is configured to blow air to the inner wall of the tire 20 and cool the coating layer L formed on the inner wall of the tire 20 by spraying the sealing liquid through the spray nozzle unit 200.

In addition, a blowing control unit 910 for on-off controlling the operation of the blowing unit 900 may be separately provided. At this time, it is preferable that a button for turning on / off the operation of the blowing control unit 910 is provided in a housing adjacent to the blowing unit 900.

It is preferable to provide a separate illuminating device (not shown) for illuminating the inside of the tire 20 so that the state of the application layer L applied to the inner wall of the tire 20 can be visually confirmed.

3 is a block diagram of a control box according to the present invention. Referring to FIG. 3, the present invention further includes an injection control module 600, a temperature control module 700, and a rotation control module 800.

The injection control module 600 is mounted on the control box 30 and controls the operation of the injection control valve 610 so that a preset injection amount is injected through the injection nozzle unit 200.

The injection control module 600 is operated by a user operation of a button corresponding to the injection control module 600 among the buttons provided on the front surface of the control box 30. [ The controller may further include a display unit for displaying a numerical value of the injection quantity to be set and a current injection quantity value at the upper portion of the button so that the user can intuitively confirm the numerical value when the button corresponding to the injection control module 600 is operated.

The temperature control module 700 may include a heating temperature control unit 710 and a nozzle temperature control unit 720. First, the heating temperature control unit 710 controls the temperature of the heating furnace 100 to a first predetermined target temperature (for example, 240 ° C. to 250 ° C.), and the nozzle temperature control unit 720 controls the temperature of the heating furnace 100 The temperature is adjusted to a predetermined second target temperature (e.g., 170 캜 to 180 캜) lower than the first target temperature.

If the temperature of the sealing liquid heated in the heating furnace 100 exceeds 250 ° C., the physical properties of the sealing liquid are changed so that the bonding force acting between the sealing liquids is reduced to an extent not suitable for application to the tire 20.

When the temperature of the sealing liquid heated in the heating furnace 100 is less than 250 DEG C, the film of the coating layer L sprayed on the inner wall of the tire 20 is improperly formed, The coating layer L can not maintain airtightness. Also, the sealing liquid is not smoothly transferred from the heating furnace 100 through the liquid discharge pipe portion 300.

When the sealing liquid is injected in a state where the temperature of the injection nozzle unit 200 is 180 DEG C or higher, the coating layer L formed on the inner wall of the tire 20 is protruded to the side wall of the tire 20 Thereby interfering with effective application.

If the sealing liquid is injected in a state where the temperature of the injection nozzle unit 200 is 170 DEG C or lower, the state of the coating layer L formed on the inner wall of the tire 20 becomes insufficient and viscosity is not formed smoothly The problem also occurs.

The rotation control module 800 controls the rotation of the in-place rotation part 500 to maintain the coating layer L of the tire 20 in the process of applying the sealing liquid to the inner wall of the tire 20 by the injection nozzle part 200. [ Adjust the speed to a preset speed.

FIG. 4 is an exemplary view illustrating a process of spraying a sealing liquid onto a tire through the spray nozzle unit according to the present invention.

4, the injection guide unit 400 closely contacts both sides of the tire 20 in a state where the tire 20 is seated on the rotary unit 500, and the tire 20 is attached to the rotary unit 500 The rotation driving motor 810 is operated by the turn-on operation of the rotation control module 800 so that the in-place rotation part 500 rotates.

The tire 20 mounted on the upper portion of the rotary unit 500 is rotated according to the rotation of the rotary unit 500 and the injection nozzle unit 200 positioned on the inner side of the opening of the tire 10, Is driven in accordance with the turn-on operation of the injection control module 600 to apply the liquid sealing liquid to the inner wall of the tire 20. [

At this time, the liquid sealing liquid injected through the injection nozzle unit 200 is heated in the heating furnace 100 and is in a high temperature state, so that it can be applied to the inner wall of the tire 20 and flow down. When the tire 20 rotates The sealing liquid applied to the inner wall of the tire 20 is kept in a coated state without flowing down by the centrifugal force.

Preferably, the rotating operation of the in-place rotation part 500 is maintained so as to further rotate for a predetermined time after the injection of the sealing liquid through the injection nozzle part 200 is completed.

At this time, the injection of the sealing liquid through the injection nozzle unit 200 is terminated, and the air blowing unit 900 is operated while the rotation of the in-place rotation unit 500 is maintained to blow air to the open part of the tire 20 The coating layer L formed on the inner wall of the tire 20 can be cooled more efficiently.

First, as shown in FIG. 5, when a coating layer L is formed on the inner side of a tire 20 mounted on a motor vehicle or a motorcycle, nails are inserted into the tire 20 through the tire 20 The leading end of the nail protrudes into the inner space of the tire 20 on the ground.

At this time, since the coating layer (L) formed on the inner side of the tire 20 is in a state of maintaining the sol or gel state, the shape of the nail is amorphous to cover the surface of the nail according to the shape of the tip of the nail.

The seal liquid of the coating layer L covers the surface of the nail and the gap between the nail and the tire 20 is blocked by the sealing liquid of the coating layer L as shown in FIG. The air pressure can be maintained.

7, the coating layer L is sealed in the direction of the inner wall of the tire 20 with respect to the fine space in which the nail has escaped even when the nail is pulled out from the tire 20, The air pressure can be maintained as it is.

8, the coating layer L returns to the original shape and maintains the state of being applied to the inner wall of the tire 20 as it is, even after the nail has completely disappeared from the tire 20. [
