2. Description of the Related Art FIG. 2 shows a printing paper cleaning apparatus to which a conventional method of supplying water and humidifying a cleaning cloth is applied. The cleaning device includes an uncontaminated cloth winding roll 2 around which an uncontaminated cleaning cloth 1 is wound, a feeding roller 3 for feeding the cleaning cloth 1 from the uncontaminated cloth take-up roll, and a state in which the cleaning cloth 1 is sandwiched. A press roller 4 in contact with the feed roller 3, a watering roller 6 for bringing the cleaning cloth 1 fed from the non-contaminated cloth winding roll 2 into contact with the running printing paper 5, and a water 7 for immersing the watering roller. And a guide roller 10 for guiding the cleaning cloth to the contaminated cloth take-up roll 9. The contaminated cloth take-up roll 9 takes up the cleaning cloth 1 after coming into contact with the printing paper 5. I have.
In the above-described cleaning device, the water 7 is transferred to the cleaning cloth 1 by the rotation of the watering roller 6, and the paper dust on the surface of the printing paper 5 is removed by bringing the cleaning cloth into contact with the surface of the printing paper 5. .

[0003] As the cleaning cloth 1, a nonwoven fabric having water retention properties is used in order to increase the amount of other contaminant particles such as paper dust adhering to the surface of the printing paper 5 per unit area. The feeding roller 3 rotates intermittently,
The cleaning cloth 1 is fed little by little toward the contaminated cloth take-up roll 9. The wetting roller 6 is disposed between the feeding roller 3 and the guide roller 10 and is always immersed in the water 7 in the watercraft 8 and presses the cleaning cloth 1 against the printing paper 5 while rotating at a low speed in the direction of the arrow. wear. The watering roller 6 feeds and humidifies the cleaning cloth 1 through a water film formed on its surface by its rotation. Winding roll 9
Is always given a winding force by a motor (not shown) via a torque limiter (not shown).

[0004]

By the way, the nonwoven fabric used as the cleaning cloth 1 generally undergoes elongation when water is applied thereto, and its elasticity is significantly reduced. That is, when water is supplied by bringing the surface of the dampening roller 6 into direct contact with the cleaning cloth 1, a frictional force and an adhesive force due to water are generated between the dampening roller 6 and the cleaning cloth 1. It is pulled in the rotation direction of the dampening roller 6 and locally expands. This elongation is shown in FIG.
As shown in FIG. 4 and FIG. 4, the cleaning cloth 1 is not uniform in the width direction but becomes particularly large near the center. For this reason, a flat and uniform contact surface cannot be formed on the cleaning cloth 1 over the entire width direction of the printing paper 5.

Even if the cleaning cloth 1 fed by the feed roller 3 is constantly wound by the take-up roll 9, the amount of elongation near the center of the cleaning cloth and the amount of elongation near the end thereof with the passage of time. Therefore, the cleaning cloth is finally wound around the wetting roller 6, and the cleaning function is disabled within a short time. Further, due to a shortage of the feeding amount of the cleaning cloth 1 with respect to the amount of foreign matter such as paper dust and contaminant particles on the surface of the printing paper 5 and other factors, the cleaning cloth cannot sufficiently take in these foreign matters, May come off to the back of the cleaning cloth. In such a case, foreign matter adhered to the surface of the watering roller 6 and contaminated the water 7 in the watercraft 8. In FIG. 1, reference numeral 1a denotes a portion of the cleaning cloth 1 which is in full contact with the wetting roller 6. The present invention has been made in view of the above circumstances, and it is possible to always reliably supply water to a cleaning cloth, and to prevent water in a watercraft from being contaminated by foreign matter that has come out of the cleaning cloth. It is an object of the present invention to provide a method for supplying and humidifying a cleaning cloth.

[0006]

According to the present invention, in order to achieve the above object, a watering roller is pressed against a cleaning cloth to supply and humidify water on the surface of the watering roller to the cleaning cloth. In the method of humidifying and supplying water to a cleaning cloth, a woven cloth is interposed between the watering roller and the cleaning cloth, and water on the surface of the watering roller is supplied to the cleaning cloth via the woven cloth. ing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a method for supplying and humidifying a cleaning cloth according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment in which the method for supplying water to a cleaning cloth according to the present invention is applied to a cleaning device for printing paper. For convenience of description, in FIG. 1, components having the same functions as those shown in FIG. 2 are denoted by the same reference numerals. The cleaning device according to the present embodiment has substantially the same configuration as the device shown in FIG. 2, and includes a non-contaminated cloth winding roll 2 on which a non-contaminated cleaning cloth 1 is wound, and a cleaning cloth from the non-contaminated cloth winding roll. Feeding roller 3 for feeding 1
A press roller 4 that comes into contact with the feed roller 3 with the cleaning cloth 1 interposed therebetween; a wet roller 6 that brings the cleaning cloth 1 fed from the uncontaminated cloth winding roll 2 into contact with the running printing paper 5; A watercraft 8 storing water 7 supplied to the attaching roller, a contaminated cloth winding roll 9 for winding the cleaning cloth 1 after contacting the printing paper 5, and a guide for guiding the cleaning cloth to the contaminated cloth winding roll 9. The vehicle includes a roller 10 and a sponge roller 11 that is partially immersed in water 7 in a watercraft 8 and abuts on a watering roller 6.

Further, as shown in FIG. 1, the cleaning device has a woven cloth 12 for water transmission interposed between the wiping roller 6 and the cleaning cloth 1. One surface of the woven fabric 12 is in contact with the dampening roller 6, and the other surface is in contact with the cleaning cloth 1. Both ends of the woven fabric 12 are fixed to a fixing member 13 disposed above the watering roller 6 and a fixing member 14 disposed below the watering roller, respectively. Fixing to these fixing members 13 and 14 is as follows.
It can be carried out using various conventionally known methods, and is not particularly limited. The woven fabric 12 is pressed by the wetting roller 6 toward the printing paper 5 so that an appropriate tension is applied. As the cleaning cloth 1, a nonwoven fabric or the like, which has a long band shape and a width dimension larger than the width of the printing paper 5 and has a water retaining property, is used. The feeding roller 3 rotates intermittently to transfer the cleaning cloth 1 to the contaminated cloth winding roll 9.
To be sent little by little. Watering roller 6
The sponge roller 1 is disposed between the feeding roller 3 and the guide roller 10 and is always immersed in the water 7 in the watercraft 8.

The watering roller 6 feeds and humidifies the cleaning cloth 1 through a water film formed on its surface by its rotation. The winding roll 9 is constantly given a winding force by a motor (not shown) via a torque limiter (not shown). The woven cloth 11 is preferably a canvas sheet, but is not limited to this, and may be any cloth as long as it is resistant to friction with the watering roller 6 and has a property of permeating water. For example, the following cloth is suitable. (1) Fabric suitable from the viewpoint of manufacturing method Cloth made by twisting filaments (ILAMENT: single fiber), cloth made without twisting, and cloth formed by bundling (the one used as a filter). Cloth formed by molding felt-like material or cotton-like material (with no fiber entangled). (2) Appropriate cloth from the material The cloth formed using cotton, synthetic fiber, wool, or metal whisker (stainless steel whiskers). (3) An appropriate fabric from the viewpoint of structure A fabric formed in one or more layers.

Next, the operation of the cleaning device according to this embodiment will be described, and the configuration will be further clarified. That is, in the cleaning device, the watercraft 8
By rotating the sponge roller 11 and the watering roller 6 immersed in the water 7 in the direction of the arrow, the water 7 in the watercraft 8 is transferred to the watering roller 6 via the sponge roller 11, and A water film is formed on the surface of
Move to 2. The woven cloth 12 sucks (permeates) the water transferred from the watering roller 6 and feeds and humidifies the cleaning cloth 1 in contact with the other surface. The watering roller 6
Is variable, and the amount of paper supplied to the cleaning cloth 1 is adjusted by changing the rotation speed of the wetting roller. By bringing the cleaning cloth 1 in a humidified state into contact with the surface of the printing paper 5,
Foreign substances such as paper dust and contaminants on the surface of the running printing paper 5 can be removed while being wiped off. The contact portion between the cleaning cloth 1 and the printing paper 5 is sequentially supplied with water and humidified via the woven cloth 12 with the rotation of the watering roller 6, whereby foreign matters on the surface of the printing paper 5 are removed. 1
Effectively removed by The cleaning cloth is sequentially fed from the non-contaminated cloth roll 2 to the contaminated cloth take-up roll 9 so that the uncontaminated portion of the cleaning cloth 1 always contacts the printing paper 5.

In this embodiment, since the woven fabric 12 is interposed between the watering roller 6 and the cleaning cloth 1, the cleaning cloth 1 is not pulled by the watering roller 6. Moreover, even if a water film is formed on the surface of the watering roller 6 (for example, in the case of water droplets), the water transferred to the woven fabric 12 is diffused in the woven fabric, and becomes flat and clean on the cleaning cloth 1. Since a uniform cleaning surface is formed, foreign substances on the surface of the printing paper 5 can always be sufficiently wiped. Also, if the cleaning cloth 1
When the paper is torn, or when foreign matter on the printing paper 5 comes out of the cleaning cloth, the foreign matter that has come out is received by the woven fabric 12, and the foreign matter on the woven cloth is removed by the cleaning cloth. Is fed to the contaminated cloth take-up roll and is sent to the contaminated cloth take-up roll, so that the water 7 in the watercraft 8 is not contaminated. In the above embodiment, the water 7 is supplied to the watering roller 6 via the sponge roller 11. However, the present invention is not limited to this, and the watering roller 6 is directly immersed in the water 7 of the watercraft 8. Roller or watering roller 6
It is a matter of course that water may be directly sprayed on the surface using a water injection nozzle.

[0011]

As described above, according to the method for supplying and humidifying the cleaning cloth according to the present invention, the watering roller is pressed against the cleaning cloth to supply the water on the surface of the watering roller to the cleaning cloth. In the method of supplying water to the cleaning cloth so as to be humidified, a woven cloth is interposed between the watering roller and the cleaning cloth, and water on the surface of the watering roller is transferred to the cleaning cloth via the woven cloth. Since the water supply and humidification are performed, the cleaning cloth does not directly contact the watering roller, and the cleaning cloth is not pulled by the watering roller, thereby preventing the cleaning function from being disabled. Thereby, the cleaning cloth can always be reliably supplied with water and humidified, and the cleaning cloth can always have a flat and uniform cleaning surface, and this state can be maintained. It can always be wiped well. Further, even if the foreign matter on the printing paper comes out of the cleaning cloth, the foreign matter that has come out is received by the woven cloth, so that the water in the watercraft is not contaminated.
