Description

Cleaning method and apparatus for dye transfer needle installed in laboratory dye dosing device {THE CLEANING METHOD AND DEVICE FOR TRANSFER NIDDLE}

The present invention relates to a method for cleaning a dye transfer needle and a device for use in a laboratory dye quantitative injector, and the present invention relates to an experimental container by accurately extracting a precise volume of a dye stock solution (mother liquor) during a dyeing experiment in a laboratory. The present invention relates to a method of cleaning a transfer needle and a device for injecting the same into a container, and a rotating brush that is rotated by hydraulic pressure to completely wash the dye inside and outside the transfer needle in a short time. .

In general, in order to test the color of the fabric in the laboratory, a small amount of the dye stock solution was separated, put into a test tube, water was mixed, and a fabric cloth was put therein to test the color of the dye.

The dye transfer method that has been used in the prior art is a computer-based air pressurization method and a self-weight method (weight type), which transfers the dye using a tube. Even after the error occurs there is a disadvantage that must be replaced, there is a problem in that only the dissolved water of a constant temperature to supply the dissolved water.

In addition, since the conventional method has a large measurement error in the main body, and a method of transferring dyes is fixed by tube pressure, the operation of the device is complicated and difficult. Although there was a conveyor moving type, when the conveyor moved to the scale and stopped in the state where the port was mounted, the scale had to be transferred upwards by the cylinder to measure the weight, which resulted in a problem that the working speed was lowered and the efficiency was lowered.

In addition, the conventional software has a disadvantage in that it takes a considerable amount of time since one set of dye input method per port (POT) is not known in the prescription input method, and the computer operation method is also a DOS method. There was a need.

On the other hand, the conventional method as described above can not grasp the remaining amount of the mother liquor in advance, it is difficult and difficult to manage the mother liquor, especially in the case of disperse dyes are deposited in the tube, brush solenoid valve, tube connection part and transferred to the correct distance There is a disadvantage that can not be done, the weight is weighed from the first dosage form later, the accuracy depends on the balance error, and it takes a lot of time for accurate measurement of the capacity type, and also the container containing the dye When handling as a glass bottle requires a great care, there was a problem that the pressure of the air is maintained only if the stopper is well fixed after replacement.

As described above, the conventional dye separator takes a lot of time to clean due to the frequent failure due to the attachment of dyes to the tube, the brush solenoid valve, etc., and in particular, if it is not operated for a long time, it takes more than half a day to clean the pump. Or, because of frequent clogging due to blockage, there was a problem that waste unnecessary spending and time.

Applicant has applied for a laboratory dye quantitative input method and apparatus (1999 Patent Application No. 99-17508) in order to solve the above problems, the invention is a number of dyes at regular intervals on the top of the body The stock table with the stock solution and the pot table receiving the stock solution are provided with a rotary turntable. This is done by installing a washing part on the rear side of the port table.

In other words, the dye transfer needle configured as a needle can be sucked into a container containing dye stock solution and then transferred to another place to be discharged. There is a problem that takes a long time in the washing method for removing the dye.

That is, after the dye is transferred to wash the dye transfer needle used in the above method, every time the needle is transferred to the washing unit, the needle is introduced into the container containing water, and then water is sprayed from the bottom surface. It was a method of washing the dye.

However, the above method was able to wash the dye on the outside of the needle, but by simply injecting water, the needle has to inhale and discharge the water several times, there was a disadvantage that takes a long washing operation, There was a severe waste of waste.

On the other hand, there is a disadvantage in that the traces of dye stains remain on the surface of the needles because of the method of washing with a weakly sprayed needle that flows with the dye, which causes the dye to remain on the surface of the needles. There was a problem that you can not experiment with color.

The present invention has been invented to solve the above problems, install a brush toward the central portion in the three directions inside the washing unit and the brush is rotated by water pressure, the washing unit after the outside of the needle is washed As it is to be installed to the sub-injection device formed to be inclined downward on the upper side of the washing unit to be separated from the cleansing, as shown in the following detailed description of the present invention.
