Description

Paint matching machine for automobile {COLOR MATCHING MACHINES FOR VEHICLES}

The present invention relates to a paint conditioner for automobiles, and more particularly, injects pigment into a pigment tank, pressurizes it with a cylinder to bleed air, and then uses a pigment control valve and a solenoid valve to precisely control the amount of pigment. By configuring it, it is possible to easily and accurately match the desired color. At this time, the pigment supply is controlled to adjust the blending amount in units of 0.1 to 0.5g/sec if the amount of the desired pigment exceeds 95%, and in units of 0.01 to 0.05g/sec if the amount of pigment exceeds 98%, so as to obtain the desired color. It is possible to adjust the color with the correct mixing ratio for each pigment.

In general, paint colorants mainly used in automobile repair factories must accurately mix pigments to obtain a desired color. If the pigment amount is not accurately measured, a color completely different from the desired color is expressed. Accordingly, in the following (Patent Document 1) to (Patent Document 3), techniques for toning by various methods are disclosed.

(Patent Document 1) Korea Patent Registration No. 10-2049699

The present invention relates to a vehicle paint conditioner having a new structure capable of effectively toning paint. After taking a sample using a camera and analyzing it, this vehicle paint conditioner automatically supplies white paint and pigment to a paint canister fixed to a fixing unit using a supply means, and rotates the fixing unit to paint the paint stored in the paint canister. Color the paint by mixing it with the pigment. Therefore, there is an advantage in that anyone can easily match paint of an accurate color.

This is to realize fast and accurate color matching by outputting the optimal color matching data by comparing and analyzing the colorimetry of the specimen data from the refinish vehicle and the specimens already in the database by using a colorimeter to make a database of automotive refinish painting specimens.

(Patent Document 3) Korean Patent Publication No. 10-2018-0016359

To provide a color-matching device and method for refinish paint capable of sufficiently supporting the color-matching work, which has conventionally been carried out through experience and intuition, mainly in automobile repair factories. This repair paint color matching device and color matching method calculates the error between the colorimetric data of the painting target part and the colorimetric data of the paint plate for each coordinate axis, and the color mixture candidate having characteristic information acting in the direction of reducing the error for each coordinate axis. , calculating the basic amount of the toning candidate corresponding to the amount of the repair paint used for painting the painting target part, calculating the error rate for each coordinate axis by dividing the error by the reference value corresponding to the colorimetric data, and By multiplying the basic amount and the error rate, the toning amount for each toning candidate is calculated.

However, these existing paint mixing techniques have the following problems.

(1) Since the amount of pigment required for coloring is not controlled, but is compared through specimens, etc., the coloring time becomes longer.

(2) Since the amount of pigment supplied to the color mixing container is not precisely measured, there is a risk that a larger amount than the desired amount of pigment is supplied to the color mixing container. This is highly likely to be toned to a color different from the desired color.

3. Air exhaust means

As shown in FIGS. 2 and 3, the air exhaust unit 230 is mounted in the air hole 221 and discharges the remaining air out of the pigment tube 210 as the pigment is filled in the pigment tube 210. allow you to do

As shown in FIG. 3 , the air discharge unit 230 includes a body 231, an adjustment bar 232, a spring 233, a closing valve 234, and an adjustment bolt 235.

main body

The main body 231 is installed to surround the air hole 221 described above, as shown in [Fig. 3], and the air leaked from the pigment tube 210 through the air hole 221 opens the pigment tube 210. It is configured to be discharged to the outside through the inlet portion. In particular, the main body 231 is formed on a surface exposed to the outside of the cylinder 220, and a predetermined space is formed therein to provide a space in which other components described later can be mounted. Reference numeral '231a', which has not been explained, is a pore formed in the main body 231 through which internal and external air passes.

control bar

At this time, one side of the control bar 232 is inserted into the main body 231 and the other side protrudes out of the main body 231. A spring 233, which will be described later, is caught at the portion inserted into the main body 231 to adjust the control bar 232. As the bar 232 is fastened, the elasticity of the spring 233 is configured to be adjustable.

closing valve

The closing valve 234, as shown in [Fig. 3], is mounted through the air hole 221 described above. At this time, both ends of the closing valve 234 are configured to close the air hole 221 as the air hole 221 is in close contact with the edge portion of the air hole 221 . To this end, both ends of the closing valve 234 are formed in a hemispherical shape, and the hemispherical shape is formed to be in contact with the edge of the air hole 221 . In addition, the hemisphere shape is configured to be connected to a bar longer than the depth of the air hole 221, so that when the closing valve 234 moves along the air hole 221, one hemisphere shape closes the air hole 221. will do Such a closing valve 234 is operated by a change in the internal pressure of the pigment tube 210 and the action of a spring 233 to be described later, as shown in [FIG. 3] to [FIG. Discharge is made, or one of the two hemispherical shapes always blocks the air hole 221 so that the pigment supply can be made.

spring

5. Solenoid valve

As shown in FIG. 2, the solenoid valve 250 is connected to the above-described pigment control valve 240 to accurately supply or block the amount of pigment supplied to the measuring cup C. In particular, the solenoid valve 250 may cause a time difference or flow rate fluctuation in the opening and closing operation of the pigment control valve 240. At this time, the solenoid valve 250 operates together with the pigment control valve 240 to supply the pigment As a safety device that makes or shuts off, it allows the desired amount of pigment to be supplied to the measuring cup (C).

As shown in [Fig. 2], in the paint conditioner 100 for automobiles according to the present invention made as described above, the desired amount of pigment is pressurized by controlling the cylinder 220 described above, and the measuring cup is passed through the pigment control valve 240. (C) is supplied, and at this time, the solenoid valve 250 is controlled so that a predetermined amount of pigment can be discharged.

On the other hand, as shown in [Fig. 6], the automobile paint color conditioner according to the present invention is preferably controlled to supply a desired amount of pigment to the measuring cup through a stable time and a small amount of mixing. To this end, the paint conditioner is stopped at a predetermined position on the measuring cup for a predetermined time (eg, 3 seconds) so that the pigments filled in the paint conditioner can be stabilized. Then, after adjusting the scale to 0 point, supply 95% of the target pigment amount to the measuring cup, then supply a small amount of pigment to control until it reaches 98% of the target pigment amount, and then stabilize again. After passing time (for example, 2 seconds), pigment is supplied in a small amount up to 100% of the final target pigment amount to be colored to a desired color. Accordingly, it is possible to accurately supply a desired amount of pigment while preventing the pigment from moving or fluctuating.

In a preferred embodiment of the present invention, in the small amount supply, when the amount of the pigment exceeds 95%, the amount is adjusted in units of 0.1 to 0.5 g/sec, and when the amount of the pigment exceeds 98%, the amount is adjusted in units of 0.01 to 0.05 g/sec. It is desirable to do This is to make it possible to control the supply of a predetermined amount of pigment without affecting the micro-amount control of the surrounding environment such as vibration.

As described above, the present invention can supply a predetermined amount of pigment through a pigment control valve and a solenoid valve to adjust to a desired color, and in particular, it is possible to more accurately measure the amount of pigment in a measuring cup through a small amount of pigment supply and stability time. there will be
