Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous automatic blending device for multi-liquid dyes, and more particularly to a device for blending liquid blended dyes used when dyeing paper yarns of synthetic fibers with liquid dyes.

Up until now, methods have been explored for blending dyes, etc., by mixing several types of primary color dyes that make up the components of a desired color with empirical measurements that correspond to the desired color sample. , requires an extremely high level of experience and skill in its formulation.

In addition, when the above-mentioned blending by the skilled person is carried out in excess of the desired amount, the blended dye made by mixing a plurality of liquid dyes is left as it is after being blended in advance. These blended dyes have various problems such as generation of dye scale and change in color tone due to changes over time. For this reason, it is necessary to mix the above-mentioned plurality of primary color liquid dyes to make a mixed dye just before using the mixed dye, and the blending ratio of such dyes requires high precision. Because of the handling, the working environment for manually performing the above-mentioned highly accurate blending work may be poor and the work may not be carried out satisfactorily. SUMMARY OF THE INVENTION It is an object of the present invention to provide a continuous automatic blending device for multi-component dyes which overcomes the above-mentioned problems and drawbacks.

Still another object of the present invention is to provide a dye tank containing a plurality of dyes, to control and mix the discharge amount of each tank according to a predetermined program, and to adjust the blended liquid to a predetermined level as needed. The object of the present invention is to provide a continuous automatic compounding device for multi-liquid dyes, which is equipped with a means for checking and giving feedback on whether the dyes are in the same composition or not, using a system consisting of an automatic sampling device, a Kokuyama color device, and a data processing device (computer).

To achieve the above-mentioned object, the present invention specifically provides an on-off valve member provided at the outlet of a plurality of dye tanks each containing different liquid primary color dyes; A control mechanism for opening and closing operations according to predetermined set values, a measuring tank for measuring the dye solution in each dye tank, and a mixing tank for receiving and mixing the measured liquid dye and organic solvent to form a blended dye. This is a continuous automatic blending device for multi-dyed dyes, which has two or more mixing tanks and uses them alternately to continuously mix and combine the blended liquid.

The continuous automatic blending device for multi-component dye according to the present invention will be explained in detail below with reference to an embodiment shown in the drawings. The undiluted dye solution is drawn up from the container by opening the door and driving the undiluted dye delivery pump 14.
An appropriate amount of Y dye is stored in the head tank 1.

Similarly, the R liquid and the B liquid are also sucked up from the dye stock solution container (not shown) and are stored in appropriate amounts in the R dye head tank 2 and the B dye head tank 3. In the case of a mounting layer, this dye head tank is used within a fixed range of 3 to 4 to cope with diversification of colors. From this state, multi-liquid I
When mixing a sex dye, the electric valves 4a, 4b, 4c are opened and closed under the control of the weighing machine 7 and the control device 20 in accordance with predetermined settings according to the desired mixing amount. The undiluted dye is allowed to flow down into the measuring tank 5, and each solution with the same set blending amount is supplied. The measured undiluted dye is transferred to a predetermined dye liquid mixing tank 9 through a three-way valve 12 by opening the electric valve 4e.
Flows down to a or 9b. When all the undiluted dyes have been measured, the electric valve 4d opens and the organic solvent cleaning liquid pumped from the organic solvent (acetone) tank ■ by the organic solvent feed pump 15 is spouted out through the measuring tank cleaning shower 8, 5. While cleaning the inside and the conduit, a predetermined amount of flow rate is measured with the meter 21 and is made to flow down into the beam liquid mixing tank 9a. still,
In order to clean the inside of the weighing tank 5 with an organic solvent, a top lid 6 of the weighing tank is attached in consideration of the working environment, and the sealing with the weighing tank 5 is performed using a sealing liquid (silicon oil) 9. . In addition, the solvent vapor generated inside the metering tank is led to the solvent recovery tower ◎ via piping and treated. The undiluted dye and organic solvent supplied to the liquid mixing tank ga are No. 10
The dye and the organic solvent are mixed together by driving the motor a and the electric motor ila for the Nol thickening machine for the time set by the timer (control device 20).

The blended dye thus produced is sent to the synthetic fiber undiluted solution coloring and spinning process ◎ through an electric valve 4i and a 4-way sliding door cock 13, where it is mixed with the paper yarn undiluted solution (dope) to make paper. Colored fibers are produced by spinning. Solvent vapor generated in the dye liquor mixing pots 9a and 9b during reception of the organic solvent is led to the solvent recovery tower ◎ via piping and treated. While the blended dye stays in the Nol dye liquor mixing tank ga, the blended dye is prepared in the same manner as the No2 dye liquor mixing tank 9b is charged into the Nol dye liquor mixing tank 9a. When the mixing beam liquid is empty, the four-way switching valve 13 is activated and the No.
2. Start feeding a new blended dye from the dye solution mixing tank gb to the undiluted solution coloring and spinning process ◎, and at the same time, the remaining liquid in the Noi beam solution mixing tank 9a is transferred to the waste dye container 18 by using the electric valve turtle m. is discharged.

In order to completely wash the remaining dye solution in the Nol dye mixing tank ga, pressurized pure water is supplied from the pure water tank ■ by the washing liquid supply pump 16 using the timer 201 to open the electric valve 4g, and It is ejected from the cleaning nozzle 22a to clean the inside of the tank and flow out into the waste dye container 18. As a secondary cleaning, a certain amount of solvent is jetted out from the Nol solvent cleaning nozzle 23a from the acetone tank 1 through the organic solvent feed pump 15 and the flow meter 21, and the discharged dye liquid is sent to the waste dye container 1.
Discharge at 8. When cleaning is completed, the electric valve 4i,
4m will be closed to prepare for receiving the next batch of mixed dye. By repeating this series of cycles in the Nol mixing tank ga and the No2 mixing tank 9b, the blended dye can be continuously supplied. As described in detail above, the continuous automatic blending device for multi-component dyes according to the present invention automatically weighs one or more types of dyes, and also mixes, discharges, and washes the weighed dyes and organic solvents. By automating the entire cycle, it is possible to continuously obtain a sea bream dyeing solution, and furthermore, the complete automation has the effect of significantly contributing to improving the working environment and saving labor.
