Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for continuously steam-treating continuously supplied fabrics or sheet-like products.

[Prior art]

Conventionally, as an example of this type of apparatus, for example, in a continuous steam treatment apparatus for fabrics in which a fabric impregnated with a dyeing solution is subjected to a wet steam heat treatment to develop color, a large number of guides are installed from the entrance to the exit of a processing chamber formed in a box shape. The rollers are arranged vertically in a staggered manner and rotatable, and the fabric that is continuously supplied from the entrance of the processing chamber is wound around each guide roller in a staggered manner, and the fabric is steam-heated while being conveyed between the guide rollers. However, a device is known in which the treated fabric is taken out from the outlet of the treatment chamber.

[Problem to be solved by the invention]

In the fabric continuous steam treatment apparatus configured as above,
The fabric supplied into the processing chamber from the entrance of the processing chamber is at a low temperature of 25 to 30°C, which is the same as the outside air.

On the other hand, since the inside of the processing chamber is maintained in an atmosphere of 100°C and high humidity of nearly 100%, the surface of the fabric that is supplied from the entrance to the processing chamber is coated within the processing chamber until the temperature reaches the ambient temperature inside the processing chamber. A large amount of moisture condenses and adheres to the surface.

In this way, when moisture adheres to the surface of the fabric, this moisture adheres to the guide roller or is stretched out in stripes on the surface of the fabric by the guide roller, which causes uneven color development on the fabric. There was a problem in that it was difficult to perform a uniform coloring process.

Therefore, in order to prevent condensation from forming on the surface of the fabric as much as possible, the speed at which the fabric is fed into the processing chamber is slowed down to allow the fabric fed from the entrance to adapt to the high temperature and high humidity inside the processing chamber. It is conceivable to supply the liquid to the guide rollers from there, but in this case there is a problem in that the processing capacity of the Rin-Ren processing apparatus will be significantly reduced.

The present invention was proposed in view of the above-mentioned problems, and it is possible to prevent dew condensation on the surface of the sheet-shaped product supplied from the entrance of the steaming treatment chamber and to significantly improve the processing capacity. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the continuous steam treatment apparatus for sheet-like products according to the present invention includes a plurality of guide rollers arranged in a staggered manner from the entrance to the exit of a steam treatment chamber formed in a box shape, In a continuous steaming apparatus for sheet-like products in which the sheet-like products are wound around a guide roller and subjected to heat-heating treatment, a heat roller is formed by providing a heating means on the guide roller near the entrance of the steaming treatment chamber. It is characterized by:

[Effect]

In the continuous steam treatment apparatus for sheet-shaped products configured as described above, the sheet-shaped products supplied from the entrance of the steam treatment chamber are heated by the temperature raising means formed on the guide roller near the entrance, and After being rapidly heated to a certain temperature and adapted to the atmosphere in the steaming chamber, it is supplied to the subsequent guide rollers.

The sheet-shaped product supplied to the guide rollers is heated to the temperature inside the steaming chamber, and is uniformly steamed without condensation while reaching the outlet.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a continuous steam treatment apparatus for sheet-like products according to the present invention will be explained based on the drawings.

This example shows an example in which the present invention is implemented in a steamer device for coloring a fabric impregnated with a dyeing solution.
The reference numeral l in the figure indicates the steamer device as a whole.

This steamer device 1 is for steaming and coloring a fabric 2 impregnated with a dyeing liquid using a dyeing liquid impregnating device (not shown), and includes a steaming treatment chamber 3 formed in a box shape with a heat insulating material around the fabric 2. , heating means 4 provided at the bottom of the steam treatment chamber 3;
Above the heating means 4, a plurality of guide rollers 5, 5, etc. are arranged in an upper stage and a lower stage, respectively. The guide roller 5 near the entrance 8 of the chamber 3 is formed as a heat roller 9 on which a temperature raising means H is formed.

As shown in FIG. 2, the temperature raising means H is provided with a nozzle pipe 11 for injecting steam at one end of the roller shaft 12 of the guide roller 5, and this nozzle pipe 11 is connected to the rotary joint 10 and the steam supply pipe 1-3. An exhaust pipe 16 is attached to the other end of the roller shaft 12 via a rotary joint 18.

The heat roller 9 provided with the temperature raising means H formed as described above has both ends of the roller shaft 12 fixed to the side walls 3a and 3b of the steaming chamber 3, like the other guide rollers 5, 5, etc. It is rotatably supported on a bracket 14 via bearings 15.

Next, the operation of the steamer device 1 configured as described above will be explained.

First, the steam supplied from the steam supply device is passed through the steam supply pipe 1.
3 and the nozzle pipe 11 via the rotary joint 14
to heat the heat roller 9 to a high temperature.

Next, when the fabric 2 impregnated with a dyeing liquid by a dyeing liquid impregnating device (not shown) is supplied from the inlet 8 of the steaming treatment chamber 3, the fabric 2 is transferred to the steaming treatment chamber 3 by the heat roller 9 and the guide roller 5.
The inside is rolled up in a zigzag pattern, and while it is smelling at the outlet 6, it is heated by the heating means 4 and subjected to color development treatment.

At this time, the temperature raising means H of the heat roller 9 provided at the entrance 8 of the steaming treatment chamber 3 causes the fabric 2 supplied from the entrance 8 to
is quickly heated to the temperature in the steaming treatment chamber 3, and after becoming accustomed to the atmosphere in the steaming treatment chamber 3, is supplied to the following guide rollers 5, 5, . . .

In this way, since the temperature of the fabric 2 supplied to the guide rollers 5, 5, etc. has been raised to the temperature inside the steaming treatment chamber 3, dew condensation may occur on its surface, or the fabric 2, which is at a low temperature, may come into contact with the fabric 2. There is no dew condensation on the surface of the cooled guide roller 5, and it is uniformly heated and colored, so it is hot.

Therefore, the fabric 2 that has been subjected to the steaming heat treatment and is led out from the outlet 6 of the steam heat treatment chamber 3 becomes a high quality product that has been uniformly processed without any spots.

In each of the above embodiments, the heat roller 9 is used as the temperature increasing means H.
Although the heat roller 9 is heated with steam, it goes without saying that the heat roller 9 may be heated with electric heat, high temperature oil, etc. instead of steam.

Further, in the above embodiment, the heat roller 9 is attached to the coloring steamer device, but it goes without saying that the heat roller 9 can be implemented in other steam treatment devices as well.

〔Effect of the invention〕

As explained above, in the present invention, the temperature of the low-temperature sheet product supplied from the entrance of the steaming treatment chamber is immediately raised by the heating means of the heating roller provided near the entrance. Dew condensation on the surface is reliably prevented.

As a result, when the sheet-shaped product is supplied from the heating roller to the subsequent guide roller and steam-treated, it is possible to perform a homogeneous steaming treatment without forming unevenness due to condensation or adhesion on the surface of the sheet-shaped product. There are advantages.

In addition, the temperature of the sheet product is immediately raised by a heating roller equipped with a heating means, which prevents dew condensation and moisture from adhering to the guide roller, reducing the feeding speed of the sheet product to the steam processing equipment. It also has the advantage of being able to speed up the process and greatly improve processing capacity.
