DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically immersing a woven fabric used for washing, fluorescent finishing, softening and the like of a rope-shaped woven fabric such as circular knitted fabric, cotton cloth, towel and the like.

[0002]

2. Description of the Related Art An automatic immersion treatment apparatus described in Japanese Patent Publication No. 1-23833, which is generally called a continuous winch type washer, has a plate-like shape having comb-like slits parallel to the traveling direction of a woven fabric. The amount of cloth retained in the treatment liquid tank is detected by a cloth amount detection sensor pivotally mounted in a balance-like manner at the position where the descending cloth is received on the inlet side of the treatment liquid tank, and the diameter of the drive roll is changed from the entrance of the cloth to the exit. The woven fabric is supplied to each treatment liquid tank with the squeezing rolls gradually reduced for each squeezing roll.

[0003]

The cloth amount detecting sensor in the conventional automatic immersion processing apparatus detects the amount of the woven fabric descending to the inlet of the processing liquid tank, so that it is immersed in the liquid of the processing liquid tank and stays there. The amount of cloth being used cannot be detected. Even if the lowered woven cloth can be introduced into the processing liquid tank, there is no action to feed the woven cloth in the liquid, so during continuous operation, the woven cloth collects only at the inlet side of the processing liquid tank and Since the cloth amount detection sensor operates even if the woven fabric is not staying in the entire liquid tank, the amount of the cloth immersed in the liquid is small, and the effect of the immersion treatment of the woven cloth is insufficient.

When the woven fabric is pressed and fed by a squeezing roll composed of a driving roll and a driven roll pressed against the driving roll, the woven fabric is wrinkled. For this reason, there is a problem in that it cannot be used for washing or softening a woven fabric that remains wrinkled when squeezed such as new synthetic fiber or rayon.

The present invention solves the above-mentioned problems of the prior art, and increases the immersion treatment effect by always keeping the woven fabric substantially uniformly in the liquid of each processing solution tank, and also reduces the woven fabric from being wrinkled. It is an object of the present invention to provide a cloth immersion treatment apparatus.

[0006]

[0007]

When the drive roll installed above the inlet side of the processing liquid tank rotates, the woven cloth is fed into the processing liquid tank, and the woven cloth immersed in the liquid forms a zigzag wave. It is sent to the exit side. When the amount of the woven fabric staying in the liquid in the processing liquid tank exceeds a predetermined amount, the cloth amount detection sensor detects the upper limit of the amount of the staple cloth. The drive roll of the next processing liquid tank rotates according to the upper limit detection signal of the cloth amount detection sensor, and the woven fabric is sent to the next processing liquid tank. When a cloth exceeding a predetermined amount in the processing liquid tank is sent to the next processing liquid tank, the cloth amount detection sensor is not detected, so that the rotation of the driving roll of the next processing liquid tank is stopped and the processing liquid is stopped. Woven cloth exceeding a predetermined amount is again accumulated in the tank.

[0008] The operation of the drive roll of each processing liquid tank is similarly controlled by a signal of a cloth amount detection sensor provided at the outlet side of each processing liquid tank, and is suspended around the drive roll and the guide roll.
The woven fabric swirled in a spiral shape is immersed in a plurality of treatment liquid tanks, and the cloth amount detection sensor in the final treatment liquid tank is detected.
The draw roll is rotated by the knowledge signal and the woven fabric is immersed.

As described above, according to the present invention, the drive roll and the drawer which feed the woven fabric into each processing liquid tank by the cloth amount detecting sensor which detects that a predetermined amount or more of the woven cloth is staying in the liquid in the processing liquid tank. Since the roll operation is controlled,
At least a predetermined amount of woven fabric stays in each of the processing liquid tanks almost uniformly at all times, so that the amount of woven cloth staying in the entire processing liquid tank can be increased, and the immersion treatment effect can be greatly increased. By the way, when a plurality of processing liquid tanks have the same number and the same capacity, the same immersion processing effect can be obtained with one automatic immersion processing apparatus of the present invention as when two to four conventional automatic immersion processing apparatuses are connected and used. It becomes possible. The drive roll and the pull-out roll that feed the woven fabric are suspended by the woven fabric.
Does not crimp) , so that the woven fabric does not wrinkle due to the feeding. Therefore, the automatic immersion treatment apparatus of the present invention can be used for washing and softening all woven fabrics including new synthetic fiber and rayon.

The diameter of the roll 16 gradually increases gradually from the inlet to the outlet (from the processing liquid tanks 2b to 2f), so that the feed amount of the woven fabric gradually increases. When the feeding amount of the woven fabric is gradually increased, the feeding of the predetermined amount of the woven fabric S is always performed smoothly without causing abnormal stagnation of the woven fabric S in each treatment liquid tank, which is practically preferable.

A feed roll 2 is provided above the inlet side of the processing liquid tank 2a.
1, a drawer roll 22 is attached to the machine frame 3 above the outlet side of the processing liquid tank 2f as in the conventional case. Although not shown in FIGS. 1 to 3 for clarity, the feeding roll 21
Is a motor (not shown) which rotates the constant speed during operation of the automatic immersion apparatus 1 to supply the woven fabric. The draw-out roll 22 is rotated by a motor (not shown) controlled by the cloth amount detection sensor 10 provided on the outlet side of the last processing liquid tank 2f. 23 is a guide roll fixed to the left and right side walls 33, 34.

A liquid flow nozzle 26 and a liquid flow nozzle 27 are provided at the inlet and outlet of each of the processing liquid tanks 2a to 2f, respectively. The liquid flow nozzle 26 has a ring-shaped pipe 28 formed with twelve obliquely downward spouts at equal intervals, and a spray-splash-preventing cover 29 welded to the outer periphery of the pipe 28, and is woven by a strong liquid flow from the spout. The cloth is sent into each of the processing liquid tanks 2a to 2f. The liquid flow nozzle 27 has substantially the same configuration as the liquid flow nozzle 26, and has a function of flowing down fluff and the like adhering to the woven fabric S after the immersion process. The processing liquid is returned from the drainage port 31 of the heating tank 8 to an automatic filter (not shown) to remove the fluff and the like that has fallen off, and is then pumped up by the pump 32 to flow from the liquid flow nozzles 26 and 27 to the processing liquid tanks 2a to 2f. It is designed to eject and supply liquid for recirculation.
