Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a guide roll, a squeezing roll, or the like in a continuous moisturizing device for a fabric in which a large number of guide rolls for continuously transporting a long fabric are installed. It relates to a continuous cleaning method.

[Conventional technology]

For example, in the pretreatment and dyeing treatment of long fabrics such as woven fabrics and knits which are industrially processed and produced, the long fabric impregnated with a predetermined treatment liquid is placed in a reactor (wet heat device) in which a predetermined wet heat is maintained. Is continuously passed through, and the treatment liquid impregnated into the fabric is subjected to a wet heat reaction to continuously perform the intended treatment such as pretreatment and dyeing treatment. And, a reactor for continuously performing a wet heat reaction treatment on a long fabric impregnated with the pretreatment liquid, the dyeing treatment liquid and the like as described above has a large number of metal guide rolls inside, The liquid-containing cloth is guided by the large number of metal guide rolls to move the cloth in a meandering shape, so that the staying time in the reaction chamber can be long.

[Problems to be Solved by the Invention]

However, in the case of a large number of guide rolls that continuously guide the long cloth impregnated with the treatment liquid as described above, the chemical liquid component or dye applied to the cloth is transferred to the surface of the guide roll. As a result, the surface of the guide roll becomes soiled, which causes a problem that the cloth to be newly guided and transferred into the processing apparatus is soiled. For example, in a guide roll in a reaction chamber that continuously guides a cloth to be impregnated with a dyeing liquid of a predetermined color, since the roll surface is contaminated by the transfer of the dye that is impregnated and impregnated into the cloth, In the same reaction humidity, when the dyeing reaction treatment of different cloths impregnated with different color dyes is continuously performed, the previous dyes adhered to the roll surface are transferred and adhered to new dyed cloths. However, there arises a problem that the cloth is soiled.

Therefore, in order to eliminate this inconvenience, particularly when different dyes are continuously dyed with different dyes using the same reaction chamber, there is a long line between the fabrics to be changed in color. By connecting the guide cloth and bringing the guide cloth into contact with the guide roll in the reaction chamber (guide transfer), by the guide cloth,
Conventionally, a means for wiping the surface of each guide roll has been adopted, but wiping the dirt adhering to the surface of the guide roll is uncertain by simply bringing the guide cloth into contact with the guide roll and transferring it. , Especially, the dirt attached to the end portions of the guide rolls located outside the guide cloth width of the guide rolls is difficult to contact with the guide cloth, so the entire surface of the guide rolls is wiped off. There was a problem that it was impossible.

[Means for Solving the Problems]

The present invention has been made in view of such conventional problems, and guide guides sequentially fed from the outside of the reaction chamber are brought into guide contact with a large number of guide rolls arranged in the reaction chamber for continuously processing a long fabric. When the surface of the guide roll is wiped, the guide cloth that guides the guide roll is swung in the width direction at the outside of the reaction chamber, and the guide cloth that is introduced into the reaction chamber is rubbed in the axial direction of the guide roll. It is to provide a method for cleaning each guide roll. Therefore, according to the present invention, since the guide cloth erected and transferred by each guide roll can be transferred while being swung in the axial direction of the guide roll, the frictional wiping force of the guide roll by the guide cloth can be increased. Since this guide cloth can be moved to both left and right ends of the guide roll by its swinging force,
The advantage is that the entire length of the guide roll can be effectively wiped.

[Examples] The present invention will be described in detail below based on examples shown in the drawings.

Reference numeral 1 denotes a fabric spreading and transporting mechanism for continuously spreading and transporting the long fabric 2. This fabric spreading and transporting mechanism 1 continuously supplies the long fabric and performs a wet heat treatment (not shown). No.) is installed near the cloth introduction port. The spreading and transporting mechanism 1 includes a spreading mechanism 3, a pair of cross guiders 4 facing each other in the width direction of the fabric to be transported, and a roll guider 5 sequentially arranged along the transporting direction of the fabric 2. There is. The spreading mechanism 3 has three screw rolls 31, 32, 33 which are parallel to each other, and these screw rolls 31, 32, 33 are rotated against the running direction of the cloth 2 by the driving force of the motor 34. At the same time, the screw is formed so that the direction of the screw is different from the longitudinal intermediate portion. Further, among the three screw rolls, the screw roll 32 located at the center thereof is provided so as to be separated from or close to the other screw rolls 31 and 33. The screw rolls 31, 32, 33 are configured to be joined or separated. Reference numeral 35 is a motor for operating the screw roll 32 in the directions of the other screw rolls 31 and 33 or in the opposite direction.

Since the cross guider 4 has a well-known structure, a detailed description of the structure thereof will be omitted. However, as shown in the figure, the cross guider 4 is a pair of cloths that are separated in the width direction of the cloth to be transferred, and if necessary, the cloth. The ears of the cloth can be held, and the ears of the cloth can be unpinched. The cloth is held so as to be movable in the width direction of the cloth.

The roll guider 5 also has a well-known structure, but this roll guider 5 has two guide rolls 51 and 52 for guiding the cloth to be transferred in a substantially S-shape, and further, both end portions of these guide rolls are respectively formed. 1 is supported by the swing mechanism 53, and the guide rolls 51 and 52 can be swung by the driving force of the swing mechanism 53 to both the left tilt and the right tilt in FIG. Reference numeral 6 denotes a detection rod having sensors 61 for detecting the positions of both side edges of the cloth 2 to be transferred.

The configuration of the embodiment has been described above. Next, the operation thereof will be described. The cloth 2 to be treated, which is continuously fed into the cloth treating apparatus (not shown), is made to run downward from the upper side in the drawing. When the cloth 2 to be processed is transferred into the processing device, the central screw roll 32 of the spreading mechanism 3 is driven by a motor 35 to drive the other screw rolls 31, 33.
Away from the screw rolls 31, 32, 3
The contact between the cloth 3 and the cloth 2 is released, and the cloth 2 which is transferred while holding the both side ears of the cloth 2 by both cross guiders 4 located on the left and right sides is spread and run. Further, the guide rolls 51 and 52 of the roll guider 5 are kept horizontal so that the cloth 2 to be transferred is located at the center of the cloth transfer path. Therefore, this treated fabric 2
At the time of transfer, the position of the ear of the cloth 2 is detected by the action of the sensor 61, and the cross guider 4 is adjusted and moved by this detection signal, and the cloth spread centering transfer is continued.

Next, when the cloth to be treated has been transferred and it is desired to wipe the guide rolls in the processing device, the guide cloth is fed into the processing device. The central screw roll 32 of the mechanism 3 is connected to the motor 3
The driving force of 5 causes the screw rolls 31 and 33 to approach each other to bring the cloths into contact with the respective screw rolls 31, 32 and 33, and both cross guiders 4 and 4 are connected to each other as shown by solid lines in the drawing. keep away. Further, the roll guider 5 causes the guide rolls 51 and 52 to alternately swing to the right and the left by the operation of the swing mechanism 53. Therefore, the guide cloth replacing the cloth 2 is spread by the spreading mechanism 3 by this operation and is transferred while being reciprocally swung in the width direction of the guide cloth by the swing operation of the roll guider 5, so that the guide cloth is installed in the processing apparatus. The guiding cloth that is guided and transferred by the existing cloth guide roll swings in the axial direction of the guide roll, and as a result,
The surfaces of the guide rolls and other guide rolls are effectively wiped.
