Description

Detailed Description of the Invention A00 Purpose of the Invention E1. INDUSTRIAL APPLICATION FIELD OF THE INVENTION The present invention relates to a wet heat treatment apparatus that applies a physical kneading effect to a fabric and continuously performs treatments such as scouring and relaxing.

E2. Prior Art Conventionally, as seen in Japanese Patent Publication No. 44-18399, this type of device has an invention in which a fabric held by a frame is rapidly moved in and out of a processing liquid to cause an impact on the liquid surface,
A method of applying a treatment liquid to a fabric that moves continuously on a wire mesh (Special Publication No. 11148/1973, Japanese Patent Publication No. 42-1/1986)
No. 1475) are known.

E3. Problems with the conventional technology All of the conventional processing devices described above have disadvantages such as unavoidable tension being applied during processing, little fir effect on the fabric, limitations on the types of fabrics that can be processed, low processing speed, and low productivity. There is.

1. Structure of the Invention 10. Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks, enables uniform and good scouring and relaxing treatment of fabric, and provides a device that can significantly improve productivity. A swinging casing is rotatably supported at one end and has a swinging drive track source at the other end, and a treatment liquid is circulated and injected into the casing, and the fabric is continuously passed through the swinging casing. The rocking casing is provided with one perforation near its bottom wall to form an inflow chamber for pressurized air between the perforated plate and the rocking casing bottom 7, and the rocking casing A number of actuating plates are positioned above and perform up and down swinging motions to push the fabric downward, and while moving the swinging casing, the fabric is floated and buried by cooperation of floating and sinking action on the fabric. The wet heat treatment is performed continuously while applying hammering force and mechanical force to the material.

The gas ejected from the holes in the perforated plate for Row 20 action rises naturally, exerts buoyancy on the fabric, keeps the fabric stretched out without tension, and floats on the liquid surface, and the rocking action of the casing causes the fabric to move toward the surface of the processing liquid in the direction of fabric transfer. The fabric is sequentially conveyed to the downstream end with no tension while floating near the liquid surface by repeatedly generating wave motion in both the counter-transfer direction and the anti-transfer direction. During the feeding process, an actuating plate that swings up and down from above the fabric suddenly hits the fabric during the lowering process, causing it to sink, and then moves on to the ascending process, where it is instantly lifted by the gas injected from the seven-hole slope. Return to floating state on the liquid surface. Therefore, the cloth 11 is affected; - When the inside is moved to 1, the 17 upper action and vertical movement are performed due to the buoyancy of the injected gas in the non-tension expanded state. The waving action of the casing is applied repeatedly as the process progresses, and the fir effect is assisted, allowing moist heat treatment such as elliptical kneading and relaxing to be performed with good quality and high productivity.

Row 3. Example Next, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a schematic side sectional view of the wide fabric glue lux processing apparatus of the present invention. This device has a built-in swing casing (7) that can maintain the treatment liquid level (3) in a wet heat treatment tank (1) that has a fabric inlet and an outlet.
7) has one end (19) as a fulcrum and the other end is a rod (20'
) is connected to a crank mechanism (20) and can be oscillated up and down, and the oscillation speed and oscillation stroke are arbitrarily adjusted depending on the product to be processed, but the oscillation speed is usually set in the range of 5 to 20 times per minute. The liquid level (3) is varied by the vertical movement of the swinging casing (7), and while the swinging casing (7) moves from the top dead center to the bottom dead center, the processing liquid overflows from the liquid drain part (7゛). The flow is stopped from the bottom dead center to the top dead center, and the bottom of the swinging casing (7) remains almost horizontal near the top dead center.
The processing liquid that has flowed out is continuously replenished from the cascade device αφ. By repeating this movement, an effective wave action can be applied to the processing liquid surface (3), and the direction and magnitude of the action can be arbitrarily adjusted by adjusting the positions of the top dead center and the bottom dead center.

A perforated plate (2) is arranged at the bottom of the rocking casing (7), and a gas (27) such as air, steam, or a mixture thereof ejected from the holes (2) is floated to the surface of the fabric (8). is floated near the processing liquid surface (3) without tension. (21)
.

(23) is a gas supply pipe, which is connected to the movement of the swing casing via a flexible tube (22). (24) is a flow control valve.

Above the treatment liquid level (3), a frame (4) is provided which is connected to the crank mechanism (5) by a rod (5゛) and performs vertical swinging motion, and a frame (4) with a thickness of 2 to 1 m is attached to the frame (4). A plurality of actuating plates (14) that act throughout the fabric are provided at predetermined intervals and protrude downward along the traveling direction of the fabric.

The cascade device αω is a wet heat treatment tank near the downstream end of the fabric (
The circulation pipe (17) is connected to the suction port (15) provided at the bottom of 1) via the pump (16) and the heat exchanger (6).
are connected to form a processing liquid circulation path.
(18) is a flow control valve. (25) is a steam population valve, and (26) is a steam trap.

The fabric (8) is passed from the inlet roll (11) to the cascade device 0.
0), and is sequentially sent into the processing liquid from the fabric chute (9), and the buoyancy of the injection gas (27) and the actuation Fi (14)
The treated liquid is transferred to the downstream end while being subjected to the vertical swinging motion of the processing liquid and the wave action of the processing liquid surface caused by the movement of the swinging casing (7). During the transfer, the fabric (8) receives the buoyancy of the gas (27) ejected from the holes (2) of the perforated plate (2), and moves from a state where it floats without tension near the processing liquid surface (3) to a swinging casing. (7) Repeatedly subjected to wave motion caused by the movement,
Further, after being thrown into the liquid by the actuating plate (14) by the vertical swing mechanism, the fabric (8) is repeatedly lifted up again as the actuated temporary rise occurs.

In this way, the combined effect of the floating of the fabric by the ejected gas, the beating of the fabric by the actuating material that performs the up-and-down rocking motion, and the formation of waves on the treated liquid level due to the movement of the rocking casing and the movement of the rocking casing creates a kneading effect on the cloth. Since it can be heated, it is possible to uniformly perform moist heat treatment such as scouring and relaxing in a short time.

C1 Effects of the Invention As described above, the present invention solves the problems of conventional devices of this type and uses an effective fir effect to improve quality and increase processing speed, thereby significantly increasing productivity. can be raised.
