Abstract

The present invention relates to a vehicle body paint change device of the vehicle, conventional paint changes are made when painting a color of a specific color and a different color, if the color is the same, there is no need to change the paint to improve the body spacing Although it is hardly secured in consideration of the use of different colors, when painting a vehicle with a different color, it is necessary to secure the distance between the specific color and the different color body at a certain distance in consideration of the paint change time. Therefore, the present invention has a problem in that the amount of production is reduced accordingly. Accordingly, the present invention provides a color change valve 11 and a color change valve 11 in which a cleaning thinner valve 12, a cleaning air valve 13, and a plurality of color valves 14a and 14b are installed. The body assembly paint side of a vehicle comprising a first assembly of a paint hose 15 connected to a color change valve 11 and a spray gun 16 connected to the paint hose 15. In the apparatus, the first assembly and the injection gun by connecting the second assembly of the color change valve 110 and the paint hose 150 connected to the color change valve 110 in parallel with the injection gun 16 After painting the first color by using the second assembly and the second color by the spray gun to clean the first color of the first assembly line, and to clean the second color of the second assembly line when painting the third color It was intended to improve productivity by allowing different colors to be coated alternately.

Description

Vehicle body paint change device

The present invention relates to a vehicle body painting paint changing device of the vehicle, in particular, the different color car that does not secure a constant interval by quickly changing the coating paint without securing a constant interval of different color car considering the change time of the coating paint The present invention relates to a vehicle body painting paint changing device capable of painting.

In general, as shown in the overall plan view of FIG. 1, a painting line of an automobile is provided with a plurality of mechanisms 10 installed on both sides and upper portions of the vehicle body 20 flowing thereon to paint the vehicle body 20 flowing through the painting line. .

In addition to painting, such a mechanical device is controlled by a computer to paint a predetermined color for each vehicle so that the coating paint can be changed. A detailed configuration of such a painting paint changing device will be described with reference to FIG. 2.

A color change valve (CCV) 11 and a cleaning thinner valve 12, a cleaning air valve 13, and a plurality of color valves 14a and 14b are installed at both sides thereof, and are provided at the outlet of the color change valve 11. An injection gun (GUN) 16 for injecting paint into the vehicle body is provided in the connected paint hose 15. The injection gun 16 controls the injection of the paint by opening and closing the solenoid valve.

Looking at the change in the coating paint of the coating device is configured as follows.

That is, when the paint of the specific color is changed after the coating of the specific color is completed, the paint of the specific color remains in the paint hose 15 from the outlet of the color change valve 11 to the injection gun 16, so that the next color valve If the paint 14 is opened, the paint mixes. First, the cleaning thinner valve 12 is opened, and the remaining paint of the specific color is pushed into the cleaning thinner to clean it, and then the cleaning air valve 13 is opened to blow out the cleaning thinner. The next color valve 14a is opened.

The like paint change there is that in the case of coating a vehicle of the particular color and the other color, when the color is the same, it is not necessary to change the coating material to the gap of the vehicle body (d ₁₎ considering productivity is not substantially put collar In the case of painting other vehicles, the distance d ₂ between the specific color and the different color should be secured in consideration of the paint change time.

Therefore, it takes a lot of time to transfer the body to the next process, there was a problem that the output reduced by that much.

The present invention has been made to solve the above problems, the technical problem is to ensure that the body of the same color, regardless of the paint color change time, the same as when the body of the same body color is not secured as quickly as the body paint The present invention provides an automobile body coating paint changing device for improving productivity by painting.

The present invention is a body painting paint consisting of a cleaning thinner valve, a cleaning air valve and a color change valve installed with a plurality of color valves, a first assembly made of a paint hose connected to the color change valve, and an injection gun connected to the paint hose. In the modification apparatus, the injection gun is achieved by connecting a second assembly identical to the first assembly separate from the first assembly in parallel.

Hereinafter, with reference to the accompanying drawings the technical configuration and effect as a preferred embodiment that can effectively achieve the object of the present invention will be described.

3 is a block diagram of a coating material changing apparatus according to the present invention, wherein a cleaning thinner valve 12, a cleaning air valve 13, and a plurality of color valves 14a and 14b are installed. And a first assembly comprising a paint hose 15 connected to the color change valve 11, and the spray gun 16 connected to the paint hose 15 is the same as a conventional configuration.

In the conventional vehicle body paint coating apparatus, the present invention is the cleaning gun valve separate from the first assembly 120, the cleaning air valve 130 and the plurality of color valves (141, 142) to the injection gun (16) Is installed in parallel to the second assembly of the color change valve 110 and the paint hose 150 connected to the color change valve (110) is installed, the first color by the first assembly and the injection gun (16) After painting, wash the first color of the first assembly line when painting the second color by the second assembly and the spray gun 16, and wash the second color of the second assembly line when painting the third color. It is to be able to paint different colors alternately.

That is, the present invention is configured by connecting two color change valves and paint hoses in parallel to the injection gun 16.

Referring to the detailed operation according to the configuration of the present invention as follows.

First, the first color is painted on the vehicle body by the injection gun 16 through the color change valve 11 and the paint hose 15 by selecting the color valves 14a and 14b of the first assembly. When the vehicle of the different colors is connected, the second color is painted on the vehicle body by the injection gun 16 through the color change valve 110 and the paint hose 150 by selecting the color valves 141 and 142 of the second assembly.

Here, the first color of the first assembly line is cleaned by the cleaning thinner and the cleaning air valves 12 and 13 when painting the second color by the second assembly, and the subsequent body of the second color car body is also the second color. In the case of different colors, the third color is prepared in advance in the cleaned first assembly line.

Thus, the first and second assemblies alternately paint the different colors of the car body flowing in the paint line, so that it is not necessary to secure a certain interval between different color car bodies made by changing the paint color as in the prior art, and the painted car body is then subjected to the next step. It is fed quickly and continuously.

As described above, the present invention does not secure a certain interval between different color bodies due to the painting change time when painting different colors of continuous or discontinuous car bodies in a state where the different color bodies are the same as the interval between the same color bodies. By changing the paint to be able to paint the car body, the car body is continuously transferred to the next process accordingly to improve productivity.
