The present invention relates to an inflator device for injecting air into a tire, and more particularly, to an inflator device for a vehicle tire in which a weight of a tire measured through a sensor can be calculated before and after injecting air into the tire. It is about.

In general, the inflator device of a tire for a vehicle is used to assemble a wheel hub of a vehicle body by supplying compressed air to the inside of the tire when installing a tire wheel (that is, an assembly in which the tire and the wheel are assembled) to be mounted on the vehicle body at an assembly plant. Device.

1 illustrates a conventional inflator device, wherein the inflator device includes a lifter cylinder 103 formed at a lower portion of the pillar frame 101, and a tire wheel 105 formed at an upper end of the rod of the lifter cylinder 103. Wheel pad 107 is configured to support by loading.

In addition, an upper frame 108 is installed at an upper portion of the pillar frame 101, and the upper frame 109 is in close contact with a tire at an upper portion of the tire wheel 105 loaded with the wheel pads 107. After sealing, an inflator dome 111 for supplying compressed air into the tire through the hollow air supply shaft 109 is installed through the air supply shaft 109.

In addition, an upper portion of the upper frame 108 may be configured to supply compressed air to the air supply shaft 109 by configuring an air compressor 113 and an air tank 115.

However, the inflator device has to be mounted in a vehicle by injecting air at a constant pressure, but the actual air injection pressure has no special method other than measuring by mounting a gauge on the valve, and pressure on a tire wheel assembled within about 10 seconds. It was very difficult to measure the total pressure by mounting a gauge.

Therefore, it is very difficult to measure the actual air pressure of all the tires assembled through the pressure gauge, and there is a problem in that the vehicle is pulled due to the imbalance of the tire air pressure.

An object of the present invention is to provide an inflator device for a vehicle tire, which is designed to solve the above problems and to calculate the air injection pressure of a tire measured before and after injecting air into the tire by a sensor. There is this.

In the inflator device used in the process of assembling the wheel and tire assembly in order to achieve the above object, the case and the wheel and tire assembly installed in the lower portion of the case to enter and descend, close to the inflator dome An inflator dome for injecting air into the tire in close contact with a tire side wheel mounted on an upper portion of the case and lifted through the lift, and an air operation unit for supplying and controlling air supplied to the inflator dome; A center cone for centering the wheel and the tire mounted on the inflator dome, a cylinder switched according to the size of the tire mounted on the inflator dome, and a position signal mounted on the lower part of the case to raise or lower the lift To check the lift sensor, mounted on the lift wheel and tire Characterized by including a weight sensor to check the weight difference before and after assembly.

According to the present invention, it is possible to improve the manufacturing quality of the vehicle by calculating the air injection pressure of the tire measured before and after injecting air into the tire by the sensor.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings, Figure 2 is a front view showing an inflator device of a vehicle tire according to the invention, Figure 3 is a sequential diagram showing an operating state of the inflator device according to the present invention. .

The inflator device 1 of the present invention provides air to a case 10, a lift 20 installed at a lower portion of the case 10 to move up and down, and a tire to be supplied through the lift 20. An inflator dome 30 for supplying, an air operation unit 40 for supplying and controlling air to supply air to the tire from the inflator dome 30, and wheels and tires mounted to the inflator dome 30 Center cone 50 for aligning the center of the cylinder, the cylinder 60 is switched according to the size of the tire mounted on the inflator dome 30, and the lift to check the position signal when the lift 20, A sensor 70 and a weight sensor 80 mounted on the lift 20 to check the difference in weight before and after assembling the wheel and the tire.

The case 10 having a predetermined height is provided with a predetermined section mounting space 12 so that the above components can be mounted therein.

The lift 20 installed below the case 10 serves to lift and lower the wheel and tire assembly 5 entered into the case 10, and the upper portion of the lift 20 is inclined. The wheel and tire assembly 5 is prevented from flowing when mounted.

At this time, the lower one side of the case 20 is equipped with a lift sensor 70 to check the position signal when the lift 20, the lift.

The inflator dome 30 installed on the upper portion of the case 10 is in close contact with the tire side wheel lifted through the lift 20 to inject air into the tire.

At this time, the pressure sensor 32 is mounted inside the inflator dome 30 to check the air pressure supplied to the tire.

The air operation unit 40 for supplying and controlling the air supplied to the inflator dome 30 is mounted on the upper portion of the case 20 and the air tank 42 for supplying air to the inflator dome 30, An air hose 44 for delivering air supplied to the air tank 42 to the inflator dome 30, and an air valve mounted on one side of the air hose 44 and controlling the air delivered to the inflator dome 30. It consists of 46.

The center cone 50 mounted between the upper portion of the case 10 and the inflator dome 30 serves to center the wheel and the tire mounted on the inflator dome 30.

At least two cylinders 60 mounted between the upper portion of the case 10 and the inflator dome 30 are mounted with the center cone 50 at the center thereof, and the size of the cylinder 60 is the size of the tire. It is formed to vary according to.

The weight sensor 80 mounted on the lift 20 serves to check the difference in weight before and after the assembly of the wheel 5 and the tire assembly 5 mounted on the lift 20.

In further detail, the weight sensor 80 is mounted on the load cell of the lift 20 to serve to compare the weight before assembling the weight between the wheel and the tire.

That is, in the tire sub-device layout for assembling and inspecting the wheel and tire assembly, the inflator step includes an entrance step of preparing the wheel and tire assembly, a close contact with the inflator dome and the amount of air to the inflator dome. Measuring step, the step of injecting air to the wheel and tire assembly after the measuring step, and the step of re-measuring the original position and the air amount of the wheel and tire assembly through the air injection step.

An embodiment of the inflator of the present invention configured as described above is as follows.

First, the wheel tire assembly 5 composed of a wheel and a tire enters the inside of the case 10 and then lifts up using the lift 20. At this time, a lift sensor installed at the lower end of the lift 20 ( 70) to confirm the ascent height.

Next, when the air is injected into the tire using the air operation unit 40 and a predetermined amount is supplied to the tire, the air pressure of the tire is checked using the dome pressure sensor 32.

Next, when the injection of air into the tire is completed, the wheel tire assembly 5 is lowered by using the lift 20, but at this time, the lift sensor 70 may be checked.

In the present invention, the wheel tire assembly 5 is lifted up using the lift 20, and the wheel tire assembly 5 which has been injected with air is lowered using the lift 20 to the lift 20. It is to calculate the injection air pressure using the weight sensor 80 is mounted.

In other words, by subtracting the weight of the tire after the air injection to the weight of the tire before the air injection and using it to distinguish between normal and abnormal state, in this case, if the abnormal state is to inform the operator by using a buzzer or a lamp. .
