Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting a supply amount of a liquid to a cloth, which allows a desired amount of treatment liquid to be uniformly applied to the entire surface of a long cloth which is continuously transferred.

[0002]

2. Description of the Related Art For example, in the textile industry, when prefabricating or dyeing an industrially produced long fabric, a suitable treatment liquid is suitable for a long fabric to be treated. It is necessary to impregnate the applied amount.

Therefore, as a conventional general applying means for impregnating the cloth to be treated with a predetermined treatment liquid, for example, after the cloth to be treated is immersed in a bath containing the treatment liquid,
A means for adjusting the liquid content by squeezing the liquid so as to obtain a desired liquid content by a pressure roll (mangle) is adopted. The pressure applied by the pressure rolls fluctuates, and the amount of liquid applied to the cloth is not uniform all the time, which makes it difficult to obtain a treated cloth of good quality.

That is, a pressure roll mechanism used as a conventional squeezing means (a liquid application amount adjusting means) by a squeezing mangle has a structure as shown in FIGS. 1 and 2. The conventional example will be described below. Reference numeral 1 denotes a pair of left and right movable arms that are pivotally supported by a horizontal support shaft 2, and bearings 3 are provided at the upper ends of both of the movable arms 1. Bearings 3 and squeeze roll 4 between each other
Is rotatably installed and held. An air cylinder or an air diaphragm 6 is provided between the lower end of the movable arm 1 and the fixed plate 5. 7 is the squeeze roll 4
It is a receiving roll arranged in parallel with.

To adjust the liquid content by the pressure roll mechanism having such a structure, a liquid-containing cloth (not shown)
Is supplied between the squeezing roll 4 and the receiving roll 7 while supplying pressurized air into the air diaphragm 6, so that the squeezing roll 4 is brought into contact with the receiving roll 7 and transferred by the contact pressure. The cloth is squeezed.

[0006]

However, in the pressure roll mechanism having such a structure, the movable arm 1 moves in the process of shifting the squeezing roll 4 from the open state to the pressure state by the operation of the air diaphragm 6. , Due to the resistance with the support shaft 2 and the fluctuation of the air pressure supplied into both air diaphragms 6, or the error in the parallelism between the flattened squeezing roll 4 and the receiving roll 7, etc. Since the contact pressure with the roll 7 fluctuates, the desired content of the liquid-containing cloth to be continuously transferred is desired even when it is desired to apply the cloth to be treated so that the liquid content is 30 to 60%. There has been a problem that it is difficult to squeeze the liquid so that the liquid ratio always becomes the set ratio.

[0007]

The present invention has been made in view of the above problems, and a cloth passage gap width formed by a receiving roll and a squeezing roll provided in parallel with the receiving roll. Is provided with a pair of rolls that can be constant,
The liquid holding cloth and the cloth to be treated are brought into contact with each other by simultaneously passing the liquid holding cloth and the cloth to be treated, which are impregnated with a predetermined processing liquid, into the gap between the pair of rolls. It is an object of the present invention to provide a liquid application amount adjusting device for a cloth, which can apply a constant liquid content to the cloth to be treated by transferring (transferring) the applied treatment liquid to the cloth to be treated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings.

In FIG. 3, reference numeral 11 denotes a receiving roll rotatably supported by a bearing 13 fixed to a frame 12, and a pressure roll 14 is arranged so as to be parallel to the receiving roll 11. Has been done. Both ends of the pressure roll 14 are rotatably supported by the upper ends of a pair of left and right movable arms 15 (only one movable arm is shown in the figure).

An air diaphragm 16 is attached to the lower ends of the movable arms 15 for expanding the lower ends of the movable arms 15 by the introduction of pressure air and for pushing the lower ends of the movable arms 15 to the right in the drawing. Since the structure of the air diaphragm 16 is known, its detailed structure is omitted.

Reference numeral 17 denotes a ball screw jackie. The ball screw jackie 17, as shown in FIG. 4, is driven by a motor 17-2, and a worm and an unillustrated worm housed inside a casing 17-3. The screw shaft 17-1 is moved in the axial direction via the worm wheel. Since the structure of this ball screw jackie is also known, further detailed description of the structure will be omitted. The tip of the screw shaft 17-1 of the ball screw jackie 17 is arranged so as to be close to the surface of the lower end of the movable arm 15 opposite to the surface on which the diaphragm 16 is attached, and the tip of the screw shaft 17-1 is It is used as a stopper that regulates the movement amount of the movable arm 15.

Reference numeral 18 denotes an endless liquid holding cloth which is pulled up from a liquid (not shown) and impregnated with a predetermined amount of processing liquid, 19
Is a cloth to be treated to which a predetermined amount of liquid is to be applied, 20 is a sensor for measuring the liquid content applied to the cloth to be treated, 22 is a signal from the sensor 20, and drives the motor 17-2 of the ball screw jackie 17. The control circuit for controlling is shown.

The structure of the present embodiment has been described above. Next, its operation will be described. Through the gap a formed by the receiving roll 11 and the pressure roll 14, the liquid holding cloth 18 and the dry treated cloth are treated. 19 is received and the roll 11 is guided. Therefore, the liquid holding cloth 18 and the cloth to be treated 19 are simultaneously run at a constant speed, whereby the treatment liquid applied to the liquid holding cloth 18 is transferred to the cloth to be treated 19 by the contact between the liquid holding cloth and the cloth to be treated. However, the transfer amount of the liquid depends on the contact pressure of the liquid holding cloth 18 and the cloth 19 to be treated.

That is, the liquid content of the cloth 19 to be treated, which is brought into contact with the liquid holding cloth 18 to transfer the liquid, is always the sensor 2
0, and if the liquid content of the treated fabric 19 has not reached a predetermined value, the sensor 20 works to drive the motor 17-2, and the screw shaft 17-1 moves to the position shown in FIG. Moves to the right at. At the same time, the air pressure supplied to the diaphragm 16 causes the movable arm 15 to move counterclockwise around the support shaft 21 as a fulcrum, so that the movable arm 15 moves toward the screw shaft 17-.
It rotates until it is regulated to the tip position of 1, and as a result, the pressure roll 14 operates in the direction of narrowing the gap a, increasing the contact pressure between the liquid holding cloth 18 and the cloth 19 to be treated, As a result, the amount of liquid transferred to the treated cloth 19 increases and the treated cloth 19
A desired amount of liquid is provided.

As described above, in this embodiment, the sensor 20 constantly measures the liquid content of the cloth 19 to be treated to which the treatment liquid has been transferred by applying pressure to the liquid holding cloth 18 impregnated with the treatment liquid. The gap width a can be controlled so that the contact pressure between the liquid holding cloth 18 and the cloth 19 to be treated is adjusted based on the measured output so that the amount of liquid containing the cloth 19 to be treated is always constant. Therefore, it is possible to always apply a constant amount of the treatment liquid over the entire surface of the fabric to be treated.

Further, in this embodiment, the position of the screw shaft 17-1 for controlling the moving amount of the pressure roll (contact pressure with the receiving roll) is controlled by the output from the sensor 20. -1 Since the movable arm 15 is pressed to the tip to keep the contact pressure between the liquid holding cloth 18 and the cloth 19 to be treated by the pressure roll constant, for example, the internal pressure in the diaphragm 16 slightly fluctuates. Also, the position of the pressure roll 14 is maintained at a fixed position, and as a result, the contact pressure between the liquid holding cloth and the treated cloth 19 is constant, and the desired quantity of liquid is transferred to the treated cloth 19 from beginning to end. The uniform liquid treatment is performed over the entire length of the long cloth.

[0017]

As described above, according to the present invention, the receiving roll 11 and the pressure roll 14 arranged in parallel to each other, the air diaphragm 16 for moving the pressure roll 14 in the receiving roll direction, and Ball screw jack 17 having a screw shaft that regulates the movement amount of the pressure roll 14 by the air diaphragm 16, and the receiving roll 1
1 and the liquid-containing treated cloth 1 that has passed between the pressure roll 14 and the pressure roll 14.
9 is a sensor 20 for measuring the liquid content, and a drive means for driving and adjusting the screw shaft with the output of this sensor. The sensor 20 constantly measures the liquid content of the cloth 19 to be treated to which the treatment liquid has been transferred by being pressed against the liquid holding cloth 18 impregnated with the liquid, and based on the measurement output, the liquid holding cloth 18 and the treated material are treated. Since it is possible to control the contact pressure with the fabric 19 so that the amount of the liquid contained in the treated fabric 19 is always constant, a constant amount of treatment is applied over the entire surface of the treated fabric. Liquid can be applied.

Further, in the present invention, the position of the screw shaft 17-1 for controlling the moving amount of the pressure roll (contact pressure with the receiving roll) is controlled by the output from the sensor 20, and the screw shaft 17- 1 The movable arm 15 is pressed against the tip, and the liquid holding cloth 1 by the pressure roll 1
Since the contact pressure between the cloth 8 and the cloth to be treated 19 is kept constant, the position of the pressure roll 14 is maintained at a fixed position even if the internal pressure in the diaphragm 16 fluctuates slightly. The contact pressure (gap width a) between the liquid holding cloth and the cloth 19 to be treated is constant, the desired liquid amount is transferred to the cloth 19 to be treated all the time, and the uniform liquid treatment is achieved over the entire length of the long cloth. The effect of being done is obtained.
