Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic dipping treatment apparatus for woven fabrics used for washing, fluorescent finishing, softening and the like of rope-like woven fabrics such as circular knitted knitted fabrics, cotton fabrics and towels.

[0002]

2. Description of the Related Art An automatic dipping treatment apparatus described in Japanese Patent Publication No. 1-23833, which is generally called a continuous winch type water washing machine, has a plate shape having comb-teeth slits parallel to the traveling direction of a woven cloth. The amount of cloth staying in the processing liquid tank is detected by the cloth amount detection sensor that is pivotally mounted like a balance at the position where the body receives the descending woven cloth on the inlet side of the processing liquid tank, and the diameter of the drive roll is exited from the inlet of the woven cloth. The woven cloth is supplied to each processing liquid tank by the squeezing rolls which are gradually reduced toward each squeezing roll.

[0003]

Since the cloth amount detecting sensor in the conventional automatic dipping processing device detects the amount of the woven fabric descending to the inlet of the processing liquid tank, it is dipped 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 fabric can be introduced into the treatment liquid tank, there is no action to feed the woven fabric in the liquid.Therefore, during continuous operation, the woven fabric accumulates only on the inlet side of the treatment liquid tank and is treated. Since the cloth amount detection sensor operates even if the woven cloth does not stay in the entire liquid tank, the amount of cloth dipped in the liquid is small and the dipping treatment effect of the woven cloth is insufficient.

Then, when the woven cloth is fed by the squeezing roller consisting of the driving roller and the driven roller which is pressed against the driving roller, the woven cloth is wrinkled. Therefore, there has been a problem that when squeezing a new synthetic fiber or rayon, it cannot be used for washing or softening a woven fabric with wrinkles.

The present invention solves the above-mentioned problems of the prior art, and makes the woven cloth stay in the liquid of each processing liquid tank almost uniformly at all times to enhance the dipping treatment effect and to prevent the woven cloth from wrinkling. It is an object of the present invention to provide a cloth dipping treatment device.

[0006]

SUMMARY OF THE INVENTION An automatic dipping treatment apparatus for a woven fabric according to the present invention is configured such that the woven fabric is suspended around a drive reel and a guide roll and swirled in a spiral manner to sequentially line a plurality of treatment liquid tanks. Detecting the amount of cloth remaining in the liquid of each processing liquid tank at the outlet side of each processing liquid tank in the automatic dipping treatment device for woven cloth A sensor is provided, and a drive reel for feeding a woven cloth is installed above the inlet side of each processing liquid tank, and the operation of the drive reel is controlled based on a signal from the cloth amount detection sensor. To do.

[0007]

When the drive roll installed above the inlet side of the treatment liquid tank rotates, the woven cloth is fed into the treatment liquid tank, and the woven cloth immersed in the liquid becomes zigzag-like. It will be sent to the exit side. When the amount of the woven fabric staying in the liquid in the treatment liquid tank exceeds a predetermined amount, the cloth amount detecting sensor detects the upper limit of the cloth staying amount. The drive roll of the next processing liquid tank is rotated by the upper limit detection signal of the cloth amount detection sensor to feed the woven cloth into the next processing liquid tank. When the woven cloth exceeding the predetermined amount in the processing liquid tank is fed to the next processing liquid tank, the upper limit detection sensor of the cloth amount detection sensor will not be detected, so the rotation of the drive roll of the next processing liquid tank will stop. Then, the woven cloth exceeding a predetermined amount is retained again in the treatment liquid tank, and the same movement is repeated.

The operation of the drive roll of each treatment liquid tank is similarly controlled by the signal of the cloth amount detection sensor provided on the outlet side of each treatment liquid tank, and is suspended by the drive roll and the guide roll.
The spirally swirling woven fabric is dipped in a plurality of treatment liquid tanks and sent out from the final treatment liquid tank to the next step.

As described above, according to the present invention, the operation of the drive roll for feeding the woven cloth to each processing liquid tank by the cloth amount detecting sensor for detecting that a predetermined amount or more of the woven cloth stays in the liquid of the processing liquid tank. Since at least a predetermined amount of woven cloth stays in each processing liquid tank almost uniformly at all times, it is possible to increase the woven cloth retention amount in the entire processing liquid tank and to dramatically improve the dipping treatment effect. Can be increased. By the way, when a plurality of treatment liquid tanks have the same number and the same capacity, the same dipping treatment effect as when the conventional automatic dipping treatment devices 2 to 4 are connected and used with one automatic dipping treatment device of the present invention is obtained. Is possible.
The drive roll that feeds the woven fabric suspends and feeds the woven fabric, so that wrinkling does not occur in the woven fabric due to the feeding. Therefore, the automatic dipping treatment device of the present invention can be used for washing and softening all woven fabrics including new synthetic fibers and rayon.

A chain 20 is suspended around a chain wheel 18 of a reel driving motor 17 and a chain wheel 19 of a drive reel attached to the bridge 14, and the operation of each of the five drive reels 16 is controlled independently. Then, the diameters of the five drive reels 16 gradually increase from the inlet to the outlet (from the processing liquid tanks 2b to 2f), and the feeding amount of the woven fabric gradually increases. When the amount of woven fabric fed is gradually increased, the woven fabric S is not abnormally retained in each processing liquid tank, and a predetermined amount of woven fabric S is always smoothly fed, which is preferable in practice.

The feed roll 2 is provided above the inlet side of the processing liquid tank 2a.
1, a pull-out 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 feed roll 21
Is constantly rotated by a motor (not shown) while the automatic dipping device 1 is in operation to supply the woven fabric. The pull-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 treatment liquid tank 2f. Reference numeral 23 is a guide roll fixed to the left and right side walls 33 and 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. The liquid flow nozzle 26 has twelve diagonally downward jetting holes perforated at equal intervals in a ring-shaped pipe 28, and a splash scattering prevention cover 29 is welded to the outer periphery of the pipe 28, and a strong liquid flow from the jetting port is used for weaving. 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 or the like adhering to the woven fabric S after the immersion process. The treatment liquid is returned from the drainage port 31 of the heating tank 8 to an automatic filter (not shown) to remove fluff that has fallen off and then pumped up by the pump 32 to the treatment liquid tanks 2a to 2f from the liquid flow nozzles 26 and 27. It is designed to be circulated and used by jetting and supplying liquid.

Each processing liquid tank 2a to 2 of the automatic immersion processing apparatus 1
In f, a cloth striking device provided with the cloth striking machine 44 shown in FIGS. 4 and 5 for striking the surface of the woven cloth S immersed in the liquid to push the woven cloth into the liquid and intermittently feeding the cloth in the traveling direction little by little. 40 are installed as follows.

Bearing 4 fixed to left and right side walls 33, 34
Two support shafts 42 are rotatably pivotally attached to the first and the first support shafts 41, and the other ends of the parallel links 43 fixed to the two support shafts 42 are connected to a hanging plate 45 of a cloth tapping machine 44 by a pin 46. Thus, six cloth tapping machines 44 are suspended horizontally from the two support shafts 42.

In the cloth tapping machine 44, five bar rods 49, which are bent and formed in a U shape on the lower side of the front plate 47 and the rear plate 48, are welded at equal intervals, and four bar rods 49 are attached to the lower surface of the bar rod 49. The cloth hitting plate 50 is welded so as to project downward. The hanging plate 45 is above the front plate 47 and the rear plate 48, the angle θ between the hanging plate 45 and the bar 49 is the same as the inclination of the partition wall 4 of the processing liquid tank 2, and the left and right of the hanging plate 45 are well balanced. It is welded to the target.

Swing arms 51 and 52 are provided at the ends of the two support shafts 42.
And the swing arms 51, 52 are connected by a link 53, and the arm 51a of the swing arm 51 and a crank pin 56 of a crank 55 directly connected to the beating plate driving motor 54 are connected by a connecting rod 57. There is. Therefore, when the motor 54 rotates, the cloth hitting board 44 swings between the raised position shown by the phantom line and the lowered position shown by the solid line in FIG. When the cloth striking plate 44 descends from the raised position and the cloth striking plate 50 is immersed in the processing liquid, the cloth striking plate 50 makes an arc motion that goes in the traveling direction of the woven fabric S (rightward in FIG. 4) as it descends. Woven fabric S
The surface of the woven fabric S is struck to push the woven fabric S into the liquid for kneading and washing, and at the same time, the woven fabric S is fed little by little in the traveling direction.

In the automatic dipping treatment apparatus 1 having the above structure,
The first processing liquid tank 2 is driven by the feed roll 21 that rotates at a constant speed.
The woven fabric S that has fallen to a is fed by the jet flow of the liquid flow nozzle 26 and is introduced into the processing liquid in a zigzag wave shape. The woven cloth S in the treatment liquid is struck by the cloth striking plate 44, the cloth striking plate 50, sent while being pushed into the liquid, and subjected to the immersion treatment, and then the fluff and the like are washed away by the liquid flow nozzle 27. Is sent to the next processing liquid tank 2b by the rotation of the drive reel 16 via the guide roll 23. In the same way,
The woven cloth S is immersed in the treatment liquid tanks 2b, 2c, 2d, 2e, and 2f while being swirled in a spiral manner.
The woven fabric S that has been subjected to the immersion treatment in the last treatment liquid tank 2f is delivered from the pull-out roll 23.

The operation of the drive reel 16 of the processing liquid tank 2b is controlled by the signal of the cloth amount detecting sensor 10 which detects the amount of the woven cloth S staying in the processing liquid tank 2a.
Similarly, the operations of the drive reel 16 and the pull-out roll 23 of the processing liquid tanks 2c to 2f are controlled. Since the cloth amount detection sensor 10 of each of the processing liquid tanks 2a to 2f detects the upper limit of the woven cloth staying in the liquid of the processing liquid tank, the processing liquid tanks are always in the continuous operation during continuous operation. A large amount of woven fabric stays substantially uniformly and is subjected to immersion treatment.

In the above embodiment, the cloth S in the liquid is sent by the cloth striking device 40, but the length of the processing liquid tank 2 is short, and the cloth is detected by the drive reel 16 and the liquid flow nozzle 26 up to the cloth amount detecting sensor. If the cloth S can be fed, the cloth hitting device 40 may not be installed.
