Description

[Detailed explanation of the idea] This invention relates to a continuous dyeing device for fabric.

As a device for continuously dyeing long lengths of fabric, one end of a liquid supply pipe with a pump interposed in the middle is connected to the bottom of the liquid preparation tank, and the fabric is continuously immersed in the dye liquid tank. The other end of the liquid supply pipe is opened upward, and the dye, auxiliary agent, and water are supplied into the liquid preparation tank according to the amount of fabric processed to mix the dye liquid, and then the pump is turned on. A device is known in which the dye liquor is sent to a dye liquor tank by driving, and the fabric is continuously immersed in the dye liquor while controlling the liquid level in the dye liquor tank to be constant. In this liquid coloring device, when a predetermined rod of fabric is impregnated with the dye liquid, in order to wash away the dye liquid remaining at the bottom of the liquid preparation tank and dye liquid tank, inside the pump, and inside the liquid sending pipe,
Tilt the dye tank to drain the remaining liquid, and open the drain valve installed at the lower end of the U-shaped liquid pipe that connects the bottom of the tank and the top of the tank. , drain the remaining liquid in the pump and liquid supply pipe, then close the above-mentioned drain valve, return the dye bath to its original horizontal position, supply cleaning water to the liquid preparation tank in this state, and turn on the pump. The pump, liquid supply pipe, and dye bath are washed with running water. At the same time, water is jetted from the fountain nozzle above the dye bath to wash the expander and squeezing rollers. After these stains are removed, the water is The supply was stopped, the dye bath was tilted again, and the drain valve was opened to drain the contaminated water.

However, in the above-mentioned conventional continuous dyeing equipment for fabrics, the washing water supplied to the liquid preparation tank can only flow in one direction to the dye bath through the liquid supply pipe and pump, so the stains in the dye bath cannot be removed. Life too,
If dirt remains on the liquid preparation tank (including the internal mixer) or pump, which is difficult to remove compared to this dye tank, remove the dirt from the liquid preparation tank or pump to remove dirt from the liquid preparation tank or pump. The drawback was that the washing water had to be kept flowing into the dye bath for a long time, and therefore a large amount of washing water was required. Also, when multiple liquid preparation tanks are provided and while the dye liquid in one liquid preparation tank is being supplied to the dye liquid tank, a dye liquid of a different color is mixed in the other liquid preparation tank. Furthermore, as mentioned above, it is not possible to immediately stop washing the dye bath and supply a new dye bath once the dirt has fallen off, and it takes a long time to change the dye bath.

This idea allows cleaning water to be circulated only through the liquid preparation tank and pump after the stains in the dye tank have been removed, thereby reducing the amount of washing water used and the time required to change dye liquids. The present invention provides a continuous fabric dyeing device that can shorten the length of time.

In other words, this idea connects one end of the liquid supply pipe with a pump interposed in the middle to the bottom of the liquid preparation tank,
In a continuous fabric dyeing apparatus in which the other end of the liquid feeding pipe is opened above a dyeing liquid tank in which the fabric is continuously immersed, a three-way solenoid valve is connected to the liquid feeding pipe on the side of the dyeing liquid tank rather than the pump. Connect the first port to the pump side and the second port to the dye bath side, connect one end of the washing water circulation pipe to the third port, and connect the other end of this circulation pipe to the third port. This continuous fabric dyeing apparatus is characterized in that the liquid preparation tank has an opening above it.

Examples of this invention will be described below with reference to the drawings.

After the fabric F is wound around the guide roller 4, dipping roller 3 and expander 5, it is guided to the nip portion of the squeezing rollers 6 and 6a. A liquid receiving tray 7 is installed above the front part of the squeezing rollers 6, 6a, a filter 8 is attached to the upper part of the liquid receiving tray 7, and a vertical liquid feeding pipe 9 is installed on the bottom surface of the liquid receiving tray 7. The upper end is connected, and the lower end opens above the dye liquor tank 1 via the dye liquor supply pipe 10. Note that the squeezing roller 6,
Fountain nozzles 11, 11 for spraying cleaning water are provided before and after 3a.

3 in front of the liquid receiving tray 7 (to the left in the figure).
The liquid preparation tanks 12, 12, 12 are arranged in parallel.
This liquid preparation tank 12 is equipped with a mixer 13, a liquid level detector 14, and a ring-shaped fountain pipe 15 inside.
A water supply pipe 18 with 7 is connected. On the other hand, one end of a liquid feeding pipe 19 is connected to the bottom of the liquid preparation tank 12 . The liquid sending pipe 19 has a feeding side vertical part 19a below the liquid preparation tank 12, a horizontal part 19b following the lower end thereof, and extends upward from the rear end, with the other end opening above the liquid receiving tray 7. Discharge side vertical part 1
A solenoid valve 20 and a pump 21 are interposed in this order in the feeding side vertical part 19a, and a connecting part between the feeding side vertical part 19a and the horizontal part 19b is provided with a solenoid valve 20 and a pump 21. A three-way solenoid valve 22 is interposed.

The above three-way solenoid valve 22 has a first port, 22
a, second port 22b and third port 22c
The first port 22a is equipped with a liquid supply pipe 1.
9 pump 21 side (lower end of feed side vertical part 19a)
is connected, the dye tank 1 side of the liquid feed pipe 19 (the front end of the horizontal portion 19b) is connected to the second port 22b, and the lower end of the circulation pipe 23 is connected to the third port 22c. The upper end is the fountain pipe 24
It opens above the liquid preparation tank 12 through. In addition, electromagnetic valves 25 and 26 for liquid drainage are attached to the lower part of the lower bent portion of the circulation pipe 23 and the lower end of the discharge side vertical portion 19c of the liquid sending pipe 19, respectively.

In the above structure, since the three-way solenoid valve 22 is interposed in the liquid sending pipe 19 on the dye liquor tank 1 side of the pump 21, the first port 22 of this three-way solenoid valve 22
When the connection between a and the second port 22b is set in a communicating manner, by filling the liquid preparation tank 12 with washing water and driving the pump 21, the washing water is drawn from the liquid preparation tank 12 as in the conventional case. It can be poured into the liquid tank 1 to clean the liquid preparation tank 12, liquid sending pipe 19, pump 21, liquid receiving tray 7, etc.
Even though the dye liquid tank 1 and liquid receiving tray 7 are clean, the liquid preparation tank 12 and pump 21
