Next, the operation of the automatic dye bath preparation device will be explained.

First, in order to prepare a stock solution of a predetermined concentration in the stock solution tank 1, the bottle body 23 is inserted into its opening 23.
The tank is placed in each recess 18 of the tank table 17 at the bottom of the tank mounting shelf 2 with the side a facing upward. Next, the small weighing balance 21 is moved by the lifting device 20.
The weight of each bottle 23 is weighed and input into the computer by repeating the lifting and lowering of the tank table 17 and the intermittent rotation of the tank table 17 by the rotary drive device 11.

After weighing the weight of each bottle, an amount of dye close to the required amount is sequentially put into each bottle body 23. Next, the lifting and lowering of the small weighing balance 21 and the intermittent rotation of the tank table 17 are repeated in the same manner, and the weight of each bottle 23 into which the dye has been added is weighed and input into the computer, and the weight of each bottle 23 containing the dye is input into the computer. The weight is subtracted to calculate the weight of each dye, and the amount of water, etc. to be injected to prepare a stock solution of a predetermined concentration is calculated by weight.

After calculating the weight of water etc. poured into each bottle body 23,
While the tank table 17 is intermittently rotated, a fixed amount of water or warm water is injected into each bottle 23 from the water tank 75 of the metered liquid supply device 7 or the metering devices 80, 85 of the hot water tank 76 through the nozzle 88. Next, the large weighing scale 21 is raised and lowered and the tank table 17 is rotated intermittently to measure the amount of water in each case. If the amount of water injected by the quantitative meters 80 and 85 is insufficient, the water dispenser 89 is Make fine adjustments by injecting the required amount of water.

As described above, after storing the required amount of dye, water, etc. in the bottle body 23 on the lowermost tank table 17 to make a stock liquid, the lid body 24 is screwed onto the bottle body 23 with a rubber packing 25 interposed therebetween. , liquid sampling port 2
Invert the bottle body 23 so that 4d is on the upper side, and turn the lid body 24 downward and open the liquid sampling port 24.
The stock liquid tank 1 is placed in the recess 18 of each tank table 17 so that the point d is radially outward of the tank table 17.

Next, in order to dispense the stock solution directly or diluted from the stock solution tank 1 into the dyeing pot 3, first, the lifting device 42 is activated and the dispensing device 5
At the same time, the nozzle 88 and the magnetic stirrer 104 are rotated and moved to a retracted wall position where they do not collide with the tank table 17. Next, the rotary drive device 11 and/or the lifting device 14 of the tank shelf 2 is operated to move the desired stock liquid tank 1 to the liquid collection position, and the rotary drive device of the pot table 4 is operated to move the desired stock liquid tank 1 to the liquid collection position. Move the staining pot 3 to the liquid injection position.

To dispense the stock liquid as it is, the lifting device 42 is deactivated and the dispensing device 5 is moved to the movable table 36.
etc., to the dispensing position by its own weight, and inserting the liquid sampling tube 49 into the liquid sampling port 24d of the stock liquid tank 1, while moving the drain receptacle 102 on the shelf board 32 to a position covering the liquid injection hole 54. After that, wash together.

Co-washing is carried out using the first, second and third dispensers 44,
This is for discharging the cleaning water remaining in the first, second and third dispensers 44, 46.
After operating the respective rotary drive devices 61 of 5 and 46 and moving the respective adjustment members 62 to the co-washing liquid amount position, the first, second and third reciprocating drive devices 56 and 5 are operated.
Activate 7,58. Due to the reciprocating operations of the first, second and third reciprocating drive devices 56, 57 and 58, the first, second and third dispensers 44, 45 and 46 dispense the stock for co-washing from the stock liquid tank 1. The liquid is collected and discharged into the drainage receiver 102, and is also discharged into the drain pipe 73 via the drainage pipe 101. Co-washing is completed by repeating the above operation several times.

To dispense the stock liquid after co-washing is completed, the drain receiver 102 is returned to its original position, and the rotational drive device 6 of the first and second dispensers 44, 45 is rotated.
1 to move the adjusting member 62 to a position where the desired dispensing amount is obtained, the first and/or second reciprocating drive devices 56 and 57 are activated. By the reciprocating operation of the first and/or second reciprocating drive devices 56, 57, a desired amount of stock solution is drawn from the stock solution tank 1 by the first and/or second dispensers 44, 45, and the stock solution is stained. The liquid is injected into pot 3.

In addition, in order to dispense another stock solution as it is into the same staining pot 3, first move the dispensing device 5 to the washing position, and then move the dispensing device 5 to the washing position,
4, 45, 46 and the liquid sampling tube 49 are cleaned.

To wash the first dispenser 44 and the like, the water dispenser 89 is operated intermittently to supply water into the washer main body 64 from its water supply and drainage pipe 68, and the first, second and third dispensers 44, 45, and 46. The water collected from the washer main body 64 by the first dispenser 44 etc. washes the inside etc., and then passes from the discharge pipe to the drain pipe 103 and the drain pipe 101 to the drain pipe 73.
leaked to. Further, water overflowing from the washer main body 64 is similarly discharged to the drain pipe 73 via the drain pipe 69 and the drain pipe 101.
After performing the above operation a required number of times to clean the first dispenser 44, etc., the water in the washer main body 64 flows out from the water supply and drainage pipe 68 to the drain pipe 73 via the drain pipe 101, and the cleaning is completed. do.

After the cleaning of the first dispenser 44, etc. is completed, the stock liquid tank 1 containing another stock liquid is moved to the liquid sampling position, and the dispensing device 5 is moved to the dispensing position as described above. Co-washing, dispensing, and washing are performed sequentially.

Furthermore, in order to collect the stock solution, dilute it appropriately, and inject it, after operating the first, second and third dispensers 44, 45 and 46 and washing together as described above, Only the third dispenser 46 is operated to draw a certain amount of stock solution from the stock solution tank 1 and inject it into the dilution tank 53. Next, water dispenser 8
9 to inject a required amount of water into the dilution tank 53 to adjust a desired dilution solution.

Next, the fourth dispenser 47 is set to the dispensing amount for co-washing, and the drain receiver 102 is set to the liquid injection hole 5.
3, the fourth dispenser 44 is operated several times to perform co-washing. After co-washing is completed, the drain receiver 102 is returned to its original position, the fourth dispenser 47 is set to the desired dispense amount, and then activated, the diluent is drawn from the dilution tank 53 through its suction pipe. Drain,
Then, the liquid is injected into the staining pot 3 from the discharge pipe.

Note that cleaning of the fourth dispenser 47 is almost the same as that of the first, second, and third dispensers 44, 45, and 46, except that water is poured into the dilution tank 53. The explanation will be omitted.

In addition, the lifting and lowering and rotation of the tank shelf 2,
Rotation of the pot table 4, various operations of the dispensing device 5,
The operation of the metered liquid supply device 7 and the like are controlled by a preprogrammed control device such as a computer.

〔Effect of the invention〕

As described above, according to the present invention, the liquid collection surface is always kept constant at the lower side of the tank, and the dispenser approaches and moves away from the side of the tank. In addition to significantly reducing the height of the pipe, the moving distance of the dispenser can be reduced without being affected by the height of the tank.
In addition, since the tanks can be placed in multiple stages, the space occupied by the device can be significantly reduced.
