Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for removing impurities on a cloth surface, which is capable of removing impurities such as thread waste, cotton dust, and nep adhering to the cloth surface.

(Prior Art) For example, a general treatment of industrially produced woven fabrics, long fabrics of cellulosic fibers such as woven fabrics is to perform tanning, desizing, scouring, bleaching, mercerizing, and then dyeing or printing. When the surface of the cloth to be transferred at the time of dyeing or printing has impurities such as lint, cotton dregs, and nep, only the part to which the impurities are attached is not dyed or printed and remains white. Therefore, in order to remove impurities adhering to the surface of the cloth, for example, in Japanese Utility Model Publication No. Sho 63-116797, an adhesive sheet feeding means, an adhesive sheet winding means, and an adhesive sheet are automatically fed from the feeding means to the winding means. And a guide means for guiding the pressure-sensitive adhesive sheet so that the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet comes into planar contact with the cloth between the supply means and the winding means. Can be moved in a direction in which the cloth is pressed against and separated from the cloth by the position adjusting means, whereby the contact pressure of the adhesive sheet to the cloth can be adjusted. No. 77674 discloses a pair of impurity adhering rolls that are pressed against each other and guide the treated cloth between the pressing parts, a curved plate for scraping off the impurities adhering to the impurity adhering rolls, and scraped off. Impurities apparatus shower nozzle provided with fabric surface for removing cleaning the impurities have been proposed.

(Problems to be solved by the invention) However, in an apparatus using an adhesive sheet, neps and the like are not removed, and since the adhesive sheet is used, the maintenance cost is high, while the impurities adhering to the impurity adhering roll are scraped and cleaned. The apparatus has a problem that nep and the like are not removed, and a drying step is required for cleaning and removing, and extra energy is required. That is, although many proposals have been made as means for removing impurities on the surface of the cloth, the effective and realizable one has not yet been found.

The inventors of the present invention have conducted intensive studies on a device for removing impurities on the surface of the fabric, and as a result, have found a new impurity removal device which has solved the problems of the existing method and completed the present invention.

An object of the present invention is to provide an apparatus for removing impurities on the surface of a cloth, which can easily and efficiently remove impurities attached to the surface of the cloth.

(Means for Solving the Problems) The above-described object is to provide a casing provided on a running path of a cloth, at least two rotating rollers provided at appropriate intervals on the running path in the casing, and the rotating roller. One or more flaps extending outwardly from the respective circumferential surfaces,
A drive means for rotating each of the rotating rollers, and a dust suction device connected to the casing, both flaps are attached so as to traverse the running path of the cloth, and the peripheral speed of both is made larger than the linear speed of the cloth. In addition, the rotation direction is opposite to each other, and the peripheral speed of one is set to be smaller than that of the other.

(Operation) In the present invention, since the flap extending outward from the rotating roller is attached so as to cross the running path of the fabric,
When the rotating roller is driven, the flaps intermittently give an impact force to the cloth, the peripheral speeds of both flaps are made higher than the linear speed of the cloth, and the rotation directions thereof are opposite to each other. Since one peripheral speed is set lower than the other, unspecified and minute vibrations frequently occur on the cloth in the casing due to the impact of the flaps, and the vibrations cause yarn waste, cotton debris, nep, etc. adhering to the cloth. The impurities float up and easily fall off the fabric and are removed by suction.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic side view of an apparatus for removing impurities on a fabric surface according to the present invention, (2) is a casing provided with slit-shaped openings (2a) on both sides provided in a running path of the fabric (1), Is a first rotating roller rotatably attached to the casing (2), and (3 ') is a second rotating roller rotatably attached to the casing (2). Six (1) flaps (4) extending outward at 60 degree intervals are provided at (3), and the second rotary roller (3 ') is provided at the second rotary roller (3').
Six second wraps (4 ') extending outward at 60 degree intervals are provided, and the first flap (4) and the second flap (4') are the first rotating roller (3). Also, when the second rotating roller (3 ') is rotated, the cloth (1) is configured to traverse the traveling path. The first rotating roller (3) is the first driving roller.
It is driven counterclockwise by a motor (5), and the peripheral speed of the first flap (4) is set to be higher than the linear speed of the cloth (1). On the other hand, the second rotating roller (3 ')
Is driven in the clockwise direction by a second motor (5 ') as a driving means, the peripheral speed of the second flap (4') is higher than the linear speed of the cloth (1), and the first flap ( It is set to be slightly lower than the peripheral speed of 4).

(6) is a known dust suction device connected to the casing (2). (7), (8), (9) are guide rollers for guiding the cloth (1), and the first rotating roller (3)
Further, when the second rotating roller (3 ') does not rotate, the cloth (1) is provided at a position where it travels in a straight line. (1
Drive rollers (0) and (10 ') for transferring the cloth (1) are driven by a motor (not shown).

Next, the operation state of the cloth surface impurity removing device configured as described above will be described.

The cloth (1) is driven by a drive roller (1
0) and (10 ') are driven and transferred, while the first rotating roller (3) is driven by the first motor (5) and the second rotating roller (3') is driven by the second motor (5 '). , First
The first flap (4) extending outward from the rotating roller (3) and the second flap (4 ') extending outward from the second rotating roller (3') are interposed between the fabric (1). A defective impact force is exerted, and impurities such as thread waste, cotton dust, and nep are knocked out and scraped off at the tips of the first flap (4) and the second flap (4 '). Impurities such as thread waste, cotton dust, and nep that were knocked out due to unspecified and minute vibration due to the impact of the flap fall off from the fabric due to the vibration.
The dust will be sucked by the dust suction device (6).

Example: 100% cotton plain weave (broad) consisting of 100 warp yarn, 100 weft yarn, 50 weft yarn, warp density 151 yarns / inch, weft density 75 yarns / inch, desizing, scouring, bleaching, mercerizing After applying
