Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a powder dye blending device suitable for weighing powder dye and diluting it with a predetermined amount of water.

(Prior art) There is a known automatic dye solution preparation device that selects a desired liquid dye from a group of pre-prepared liquid dyes with a fixed concentration, takes out a predetermined amount of the dye, and dilutes it to a predetermined concentration. However, it is not widely used because there is a limit to the concentration of liquid dye, and because it is a liquid, it is easily deteriorated. On the other hand, it is difficult to automate powder dyes because it is difficult to automatically transport the weighed dye, and the equipment that comes into direct contact with the dye gets dirty with the dye. Everything was done manually.

(Problems to be solved by the invention) In the past, the mixing of powder dyes was done manually, which caused the problem that the work environment was contaminated with powder dyes. Also, to solve this problem,
A plurality of powder dye cutting machines are installed along a diagonally arranged weighing plate, with the cutting ports opening above the weighing plate, and the desired powder dye is discharged onto the weighing plate to obtain a predetermined amount. Attempts have been made to inject a predetermined amount of water onto the top of the weighing pan to flush the powder dye on the weighing pan into the liquid receiving tank below, and dilute it at the same time. The cutting opening is located just above the weighing pan through which water flows, and water is injected from the upstream side of the cutting opening, so the powder dye at the cutting opening gets wet, causing variations in the amount of powder dye cut out, and the weighing pan is tilted. Since the flow rate is slow, a large amount of water is required to wash away the powder dye on the weighing plate, which poses the problem of not being able to obtain a highly concentrated dye solution.

This invention allows powder dyes to be mixed automatically, and there is no variation in the weight of powder dyes.
Furthermore, the present invention provides a blending device that can obtain a highly concentrated dye solution.

(Means for solving the problem) In order to solve the above problem, in this invention, a weighing device is provided on a transfer table that reciprocates along a horizontal rail, and a weighing pan is detachably attached to the weighing device. Place a plurality of powder dye cutting machines above the rail so that their cutting ports open in sequence on the movement path of the weighing pan, and lift the weighing pan to one end of the rail. A weighing plate reversing device for inverting and discharging the powder dye on the weighing plate downward; and a liquid receiving tank located below the inverted weighing plate with an open top surface and a liquid feeding pipe connected to the lower end. and a shower device for spraying dilution water onto the inside of the weighing pan in the inverted state.

(Function) The transfer table is moved along the rail and stopped below the cutting port of the desired powder dye cutting machine in order, and the desired amount of powder dye is transferred from each cutting machine to the weighing pan on the transfer table. After cutting out the final powder dye while weighing it with the scale below, move the transfer table to one end of the rail, and then drive the weighing plate reversing device to lift the weighing plate on the transfer table. The powder dye in the weighing pan is inverted, and the powder dye in the weighing pan is discharged into the liquid receiving tank below, and dilution water is injected from the shower device onto this weighing pan to wash the powder dye in the weighing pan downward. Dilute to desired concentration.

The guide rail 2 is inserted into a sliding block 6 on the lower surface of the transfer table 5 located above it, and the feed screw 3 is also screwed into a nut 7 on the lower surface of the transfer table 5. A weighing device 8 is fixed to the upper surface of the transfer table 5, and a weighing plate 9 is removably placed on a support frame 8a fixed to the weighing device 8. This weighing pan 9 is gutter-shaped with a V-shaped cross section (see Figure 2), and its rear end (the end on the side of the reversible motor 4) is closed with an end plate 9a, and its valley bottom line 9b is inclined backward. Two ear plates 9c, front and rear, are protruded from both sides, and horizontal through holes are bored in the ear plates 9c.

A plurality of powder dye cutting machines 11 are arranged in a row parallel to the lower guide 2 on the upper frame 10 above the lower rail 1, and their cutting ports 11a open above the passage of the weighing pan 9. .

On the opposite side of the reversible motor 4, there is provided a reversing shaft 12 located slightly below the guide rail 2 and feed screw 3 in the width direction (direction perpendicular to the plane of the paper) (see Fig. 2). The lower ends of a pair of left and right L-shaped reversing levers 13, 13 are fixed to this reversing shaft 12. This L-shaped reversing lever 13 has a vertical portion 13a.
and a horizontal portion 13b, and the tip of the vertical portion 13a is fixed to the reversing shaft 12. A drive lever 14 is fixed to one end of the reversing shaft 12, and the lower frame 1 is attached to the tip of the drive lever 14.
Air cylinder 1 for reversal is swingably attached to
5 piston rods 15a are connected, and when this piston rod 15a is retracted, the vertical portion 13a
stands up and the horizontal part 13b is located horizontally, its height matches the through hole of the ear plate 9c of the weighing pan 9, and the tip faces the reversible motor 4 side. falls horizontally forward and the horizontal portion 13b stands up.

A cone-shaped liquid receiving tank 21 is installed in front of the reversing device consisting of the above-mentioned reversing shaft 12, reversing lever 13, drive lever 14 and air cylinder 15,
The lower end thereof is connected to a dye solution service tank (not shown) through a liquid feeding pipe 22, and a liquid feeding pump 23 is interposed in this liquid feeding pipe 22. A ring-shaped shower tube 2 for spraying dilution water onto the inner surface of the liquid receiving tank 21 along the inner side of the upper edge of the liquid receiving tank 21
4 is fixed, and a main water supply pipe 27 is connected to this ring-shaped shower pipe 24 via a first water supply pipe 25 and a first solenoid valve 26.
A flow meter 28 is interposed at 7. On the other hand, liquid receiving tank 2
A U-shaped second shower tube 29 for injecting dilution water toward the inside of the inverted weighing pan 9 is installed in an inverted manner above the weighing pan 2.

(Effect of the invention) This invention involves feeding a weighing pan along a horizontal rail, cutting out a desired amount of the desired powder dye from an upper powder dye cutting machine onto the weighing pan, and then turning the weighing pan into powder. After leaving the body dye cutting machine, the weighing pan is turned over and the powder dye is discharged into the liquid receiving tank below, and the weighing pan is washed with a shower of dilution water, and at the same time, dilution water is added to the powder dye to dilute it. Therefore, the preparation of powder dye can be easily automated.
A powder dye cutting machine is arranged above the rail for transferring the weighing pan, a liquid receiving tank and a shower pipe are provided at one end of the rail, and the shower pipe is spaced apart in front of the powder dye cutting machine. Because of this, the cutting opening of the powder dye cutting machine will not get wet with dilution water and will not interfere with cutting out the powder dye, and since the weighing pan is turned over and the powder dye is released, after this discharge, Very little powder dye remains on the weighing pan,
Therefore, only a small amount of dilution water is required to wash away the powder dye, and a highly concentrated dye solution can be prepared.
