Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a continuous heating device for fabric that is equipped with a large number of guide rolls for continuously transporting a long fabric. etc., regarding a continuous wiping method.

[Conventional technology]

For example, the pretreatment and dyeing treatment of long fabrics such as 9 knitted fabrics that are industrially processed and produced are carried out by impregnating the long fabrics with a predetermined treatment liquid and placing them in a reaction device (thermal device) that maintains a predetermined temperature. The treatment liquid impregnated into the fabric is caused to undergo a thermal reaction by passing through the fabric continuously, thereby continuously performing desired treatments such as pretreatment and dyeing treatment.

A reaction apparatus for continuously subjecting a long fabric impregnated with the above-mentioned pre-treatment liquid, dyeing treatment liquid, etc. to thermal reaction treatment is equipped with a large number of metal guide rolls, and the above-mentioned The liquid-containing fabric is guided by a large number of metal guide rolls to move the fabric in a meandering manner, thereby ensuring a long residence time in the reaction chamber.

[Problems to be solved by the invention]

However, in the case of multiple guide rolls that continuously guide a long fabric impregnated with a treatment liquid as described above, the chemical component or dye applied to the fabric may be transferred to the surface of the guide roll. As a result, the surface of the guide roll becomes dirty, resulting in the problem of staining the fabric to be newly guided and transferred into the processing apparatus. For example, in the case of a guide roll in a reaction chamber that continuously guides a fabric to be impregnated with a dye solution of a predetermined color, the roll surface is contaminated due to transfer of the dye applied to and impregnated into the fabric. When the dyeing reaction treatment of different fabrics impregnated with dyes of different colors is successively carried out in the same reaction chamber, the previous dye attached to the roll surface transfers and adheres to the newly dyed fabric. A problem arises in that the fabric is stained.

Therefore, in order to eliminate this problem, especially when dyeing different types of dyes using different color dyes using the same reaction chamber, a long length of cloth should be placed between the fabrics undergoing color change. Connect the guide cloth and bring it into contact with the guide roll in the reaction chamber (
Conventionally, a method has been adopted in which the surface of each guide roll is wiped with the guide cloth by wiping the surface of each guide roll with the guide cloth. It is difficult to clean the adhered dirt, and in particular, it is difficult to clean the dirt adhering to the ends of the guide rolls that are located outside the width of the guiding cloth. For some reason,
There was a problem in that it was impossible to wipe the entire surface of the guide roll.

[Means to solve the problem]

The present invention has been made in view of these conventional problems, and includes guiding cloth that is sequentially fed from outside the reaction chamber and brought into guide contact with a large number of guide rolls disposed inside a reaction chamber in which long fabrics are continuously processed. When wiping the surface of the guide roll, the guide cloth that guides the guide roll is swung in the width direction at the introduction section outside the reaction chamber, and the guide cloth introduced into the reaction chamber is oscillated in the axial direction of the guide roll to cause friction. An object of the present invention is to provide a method for wiping each guide roll.

Therefore, according to the present invention, the guide cloth that is erected and transferred by each guide roll can be transferred while being swung in the axial direction of the guide roll, so that the frictional wiping force of the guide cloth on the guide roll is reduced. Furthermore, the guiding cloth can be moved to both the left and right ends of the guide roll by its swinging force, so that the entire length of the guide roll can be effectively wiped.

(Example) The present invention will be described in detail below based on an example shown in the drawings.

Reference numeral 1 denotes a fabric spreading transfer mechanism for continuously spreading and transferring a long fabric 2. It is installed near the fabric inlet of 1). This spreading transfer mechanism 1 includes a spreading mechanism 3, a pair of cross guiders 4 disposed opposite to each other in the width direction of the fabric to be transferred, and a roll guider 5, which are sequentially arranged along the transfer direction of the fabric 2. There is. The spreading mechanism 3 has three screw rolls 31, 32, and 33 that are parallel to each other, and these screw rolls 31, 32, and 33 are rotated against the running direction of the fabric 2 by the driving force of the motor 34. In addition, the screws are formed so that the directions of the screws are different at the intermediate portion in the longitudinal direction. Further, among the three screw rolls, the screw roll 32 located in the center is provided so as to be able to separate from or approach the other screw rolls 31 and 33, and the operation of this screw roll 32 separates the fabric 2 from each other. It is configured so that it can be joined to or separated from the screw rolls 31, 32, and 33.

35 is a motor for moving the screw roll 32 in the direction of the other screw rolls 31 and 33 or in the opposite direction.

Since the cross guiders 4 have a well-known structure, a detailed structural explanation thereof will be omitted. It is held so as to be movable in the width direction of the fabric so that the selvedges of the fabric can be held and the selvedges of the fabric can be released.

The roll guider 5 also has a well-known structure, but this roll guider 5 has two guide rolls 51 and 52 that guide the fabric to be transferred in a substantially S-shape, and furthermore, both ends of these guide rolls are The guide rolls 51 and 52 are supported by a swing mechanism 53, and the guide rolls 51 and 52 can be swung to the left or right in FIG. 1 by the driving force of the swing mechanism 53. Reference numeral 6 denotes a detection rod incorporating a sensor 61 for detecting the position of both side edges of the fabric 2 being transferred.

The configuration of this embodiment has been described above, and its operation will now be described. The fabric 2 to be treated, which is continuously fed into a fabric processing apparatus (not shown), is run from the top to the bottom in the drawing. When the fabric 2 to be treated is transferred into the processing apparatus, the central screw roll 32 of the cloth spreading mechanism 3 is driven by the motor 35, and the other screw rolls 31.3
3, the screw rolls 31, 32 .
33 is released from contact with the fabric 2, and the fabric 2, which is being transferred with both side edges of the fabric 2 held between the cross guiders 4 located on both the left and right sides, is allowed to spread out.

Further, each of the guide rolls 51 and 52 of the roll guider 5 is kept in a horizontal state so that the fabric 2 to be transferred is located at the center of the fabric B feeding path. Therefore, when the fabric 2 to be treated is transferred, the fabric 2 is moved by the action of the sensor 61.
The cross guider 4 is adjusted and moved based on this detection signal to continue spreading and centering the fabric.

Next, when the transfer of the fabric to be processed is completed and it is desired to wipe the guide rolls etc. inside the processing equipment, a guiding cloth is supplied into the processing equipment. The central screw roll 32 of the mechanism 3 is connected to the motor 35.
The driving force causes the guiding cloth to approach the other screw rolls 31, 33 and bring the guide cloth into contact with each screw roll 31, 32, 33, and both cross guiders 4.4 are kept away from the guiding cloth as shown by solid lines in the drawing. . Furthermore, the roll guider 5 swings each guide roll 51, 52 alternately to the right and left by the operation of the swing mechanism 53. Therefore, by this operation, the guide cloth that replaces the cloth 2 is spread in the spreader mechanism 3, and is transferred while being reciprocated in the width direction of the guide cloth by the swinging action of the roll guider 5, so that it is transferred into the processing equipment. The guide cloth guided and transferred by the installed fabric guide rolls swings in the axial direction of the guide rolls, and as a result, the surfaces of these guide rolls and other guide rolls are effectively cleaned. It is something.

(Effects of the Invention) As described above, the present invention has a spreading mechanism that combines a plurality of screw rolls that are forcibly driven in the fabric transfer direction of a long fabric transfer path, and a fabric spreading mechanism that A pair of opposed cross guiders and a roll guider capable of swinging are arranged in this order, and when the fabric is transferred, the fabric is spread and transferred by the cross guider,
The roll guider is fixed at the center, and the screw roll is released from contact with the fabric, and when transferring the guide fabric, the cross guider is released from contact with the guide fabric, and the screw roll and the guide fabric are released from contact. This is a guide roll wiping method in which the guide roll is held, and further the roll guider is swung in the left and right inclination directions, and the guiding cloth is swung in the axial direction of the guide roll.

Therefore, according to this, the guiding cloth that is erected and transferred by each guide roll can be transferred without being swung in the axial direction of the guide roll, so that the frictional wiping force of the guiding cloth on the guide roll is reduced. Intensified, and furthermore, this guiding cloth,
