Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a steam setter that moisturizes and prevents twisting of textile products such as cotton and wool.

[Prior art]

Steam cent is used to humidify and prevent twisting of textile products such as cotton and wool, but the conventional method is to use an aluminum setter body 21 as shown in Figure 2. After putting the fiber products 28, mainly yarn, into a box made of plastic, and closing the door, perform a series of vacuum-steam blowing, maintaining for a certain period of time, and breaking the vacuum, then open the door and remove the fibers. The product 28 is taken out and the steam setting is completed, but since the textile product 28 taken out in this way has just been taken out immediately after being steamed, its temperature is high and it has a large amount of moisture. Therefore, it releases steam and disturbs the indoor conditioning, and the textile product 2
8 is also difficult to handle, so as a countermeasure, after completing the steam setting, the setter body 21 is once evacuated to remove excess moisture and lower the temperature to make it easier to handle after removal. It started to be done.

To explain this with reference to FIG. 2, first, the valve 26 is opened, the steam valve 25 is opened with the valve 27 closed, and the steam set is performed.

All the drain generated inside the setter body 1 during this steam setting flows into the drain tank 24, but if the valve 26 is closed when the steam setting is completed and the inside is evacuated by the vacuum pump 23, the setter body 1 The steam inside the textile product 28 and the excess water contained in the textile product 28 are pulled by the vacuum pump 23 and condensed in the condenser 22 on the way, becoming low-temperature drain, leaving the textile product 28 in a fairly dry state, but the This drying step is especially necessary in heat setting for the purpose of.

Therefore, the drain accumulated in the drain tank 24 is released to the outside by opening the valve 27.

The above steam setting method is the method currently employed, but as can be seen in Figure 2, it is necessary to newly install a drain tank 24, a discharge valve 27, etc. at the bottom of the setter body 21. No.

On the other hand, if the steam setter is a large device, there is no problem because it will dig a deep pit in the floor and install the devices there. However, if the steam setter is a small device and is installed on the floor, for example, a spinning machine In the case of a continuous steam setter installed in the automatic conveyance line from the machine to the hoist, the bit cannot be dug into the floor, and the conveyor conveyance line cannot be installed too high above the floor. There's a problem.

[Purpose of the invention]

The present invention has been made in order to solve the above-mentioned conventional problems, and provides an extremely compact steam setter that does not require the installation of a drain tank and a focus for discharging the drain inside the setter body. The purpose is to

[Structure of the invention]

To achieve the above object, the steam setter of the present invention is constructed by connecting a vacuum pipe connected to a vacuum pump that evacuates the inside of the center body to the lowest position at the bottom of the setter body where the drain can be easily removed. However, it is desirable to use a water ring type vacuum pump, which can be used to discharge steam and condensate from the setter body.

In the above steam setter, the vacuum piping that connects to the vacuum pump is connected to the lowest position of the center body where it is easy to suck out the drain from the setter body, so after the steam set is completed, the steam inside the setter body and the bottom of the body are All accumulated drain can be sucked out with a vacuum pump, and the inside of the setter body is vacuumed to dry the textile products inside and the inside of the center body, and then the vacuum is broken and the textile products are taken out. Textile products can be easily handled without disturbing their condition.

〔Example〕

An embodiment of the present invention will be explained below with reference to the drawings. Fig. 1 shows a small steam setter, and inside the setter body 1 there is a textile product wound around a bobbin. It owns a certain pipe thread 2.

At the lowest position at the bottom of the setter body 1 of the steam setter that can hold the pipe thread 2, where the drain can be easily removed, there is a vacuum pipe 9 connected to a water ring type vacuum pump 3 that evacuates the inside of the center body 1. Connected.

Next, the door (not shown) of the setter main body 1 is closed while holding the pipe yarn 2, and the water ring type vacuum pump 3 is operated to evacuate the inside of the setter main body 1 to about 40 Torr.

5 in Figure 1 is a saturator, which stores hot water inside.
The heating valve 8 always maintains a constant pressure or constant temperature.

Next, when the steam injection valve 6 is opened, the steam in the saturator 5 flows into the setter body 1, but as the pressure in the saturator 5 decreases, steam is replenished from the heating valve 8.

The function of this saturator 5 is that since the steam supplied from the boiler is high in pressure and temperature, it is passed through hot water to lower the temperature of the steam, and even when it flows into the setter body 1, it does not become dry steam. It is intended to do so.

Next, when the inside of the setter main body 1 reaches the set temperature, for example, 70 to 80° C. in the case of hair, the air injection valve 6 is closed and left in this state for 10 to 20 minutes.

During this time, if the internal temperature drops due to heat radiation from the surroundings, steam is replenished from the steam injection valve 6 to maintain the set temperature.

At the end of the scheduled time, steam centage is completed, and at this point the vacuum pump 3 is activated, and the drain accumulated at the bottom of the setter body 1 and the steam inside the setter body 1 are sucked together through the vacuum valve 4.

As the vacuum inside the setter body 1 rises, water vapor is emitted from the tube thread 2, which has reached a high temperature of 70 to 80 degrees Celsius, and excess moisture and heat are removed, and the wetting of the inner surface of the setter body 1 due to steam is vacuum dried. It will be done.

The vacuum is drawn to about 60 Torr, and the pressure is returned to atmospheric pressure using the vacuum break valve 7, and then the door is opened to take out the tube 2. However, since the inside of the center main body l has been evacuated once, even if the door is opened, there is nothing outside. No steam is released to the pipe thread 2.
Since the fibers have been cooled down to about 42 to 43'C, twisting has stopped, and even if they are carried to the next process, there is no problem in operation.

The vacuum pump 3 used in such equipment is a pump that does not mind the entry of some water or heat, such as a water ring pump, water jet pump, steam ejector pump, etc. .

〔Effect of the invention〕

As explained above, according to the steam setter of the present invention, there is no need to install a drain tank for discharging the drain inside the setter body and its focus, making the surroundings of the setter body very simple. The present invention can be effectively applied to small-sized steam setters,
The equipment cost is low, and even when installed as a continuous setter between the spinning machine and the winding machine, it can be assembled compactly enough to be applied to existing equipment, making it an extremely useful device. Become.

In addition, after the steam set is completed, all the steam and drainage accumulated inside the setter body can be sucked out with a vacuum pump, and the textile products are taken out after drying, so there is no need to disturb the indoor condition. Another advantage is that the textile product can be easily handled after being taken out.
