Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Use of the Invention] The present invention adheres to a surface of a belt-shaped product in a transfer process in which a belt-shaped product such as a woven fabric, a cloth or a film such as lace, and a paper product is continuously run. The present invention relates to an apparatus for continuously removing impurities such as lint and fluff.

[Background of the Invention]

For example, the step of pretreating an original fabric of an industrially produced woven fabric, a long fabric such as a lace, and then printing the fabric,
It is well known that pre-treatment is carried out by tanning, desizing, scouring and bleaching, and then the pre-treated fabric is continuously dyed on a printing machine. However, if fluff, yarn waste, or impurities such as fiber carbides generated during the hair-burning treatment adhere to the surface of the fabric to be subjected to the above-mentioned textile printing machine, a defect portion of the dyeing due to the impurities occurs and good printing cannot be performed. It will be. For this reason, conventionally, in order to remove impurities such as thread waste adhering to the fabric surface immediately before printing, it is also considered that the impurities on the fabric surface are blown off by using a blower or the like. However, there was no certainty as a means for removing impurities.

[Object of the Invention]

The present invention has been made in view of the above, and is adhered to the surface of a belt-shaped product such as a cloth, a film, or a paper by contacting the surface of the belt-shaped product with an adhesive roll formed of an adhesive material. It is an object of the present invention to provide a continuous cleaning device for strip-shaped products, which can continuously and surely remove impurities with an adhesive roll.

Example of Invention

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

Reference numeral 1 denotes an adhesive roll rotated by a motor (not shown). This adhesive roll 1 is formed by forming a material having a constant adhesiveness into a roll shape. For example, as the adhesive material, Otaka Rubber Industry Co., Ltd. The product name of "Tucky" can be used. In the circumferential direction of rotation of the pressure-sensitive adhesive roll 1, a shower nozzle 2 for washing and heating for spraying hot water toward the pressure-sensitive adhesive roll 1, a knife-shaped dust removing means 3, and a draining means 4 by cold air or hot air are arranged in this order. It is set up. The pressure-sensitive adhesive roll 1 maintains a high adhesive force by keeping the roll temperature at 20 ° C to 40 ° C, so that the adhesive roll 1 is kept warm and the dust adhered to the surface of the roll 1 is kept. In order to enhance the swelling and falling off property, hot water of 20 ° C. to 40 ° C. is constantly jetted from the shower nozzle 2 and applied to the surface of the adhesive roll 1. If the heat-retaining temperature of the pressure-sensitive adhesive roll 1 is 20 ° C or lower, the adhesive strength will decrease, and if it is 40 ° C or higher, the adhesiveness will be increased but the shape retention will be impaired, and the surface will be prone to scratches and durability. Therefore, the temperature of the hot water sprayed from the nozzle 2 is limited to 20 ° C to 40 ° C in this embodiment. The dust removing means 3 is a knife-like plate material for removing dust such as lint attached to the surface of the adhesive roll 1 from the surface of the adhesive roll 1, for example, urethane,
Although it is made of a resin plate such as nylon or Teflon, the present invention is not limited to this, and may be a brush slidably contacting the surface of the adhesive roll 1. The contact pressure between the dust removing means 3 and the adhesive roll 1 can be appropriately adjusted by a known elastic pressure means. The water draining means 4 blows room temperature air or hot air toward the surface of the adhesive roll 1,
The purpose is to blow off the moisture adhering to the surface of the adhesive roll 1 to dry it. 5 is a guide roll of the cloth 6,
Reference numeral 7 denotes a drawing roll of the cloth 6, and the cloth moving between the guide roll 5 and the drawing roll 7 is arranged so as to come into contact with the surface of the adhesive roll 1. The guide roll 5 can be moved so that the joint area between the cloth 6 and the adhesive roll 1 can be adjusted, that is, as shown by the chain line. Reference numeral 8 is a saucer having a drainage port 9.

The structure of this embodiment is as described above. Next, the operation thereof will be described. When the adhesive roll 1 and the pull-out roll 7 are rotated, the cloth 6 is transferred while being in contact with the adhesive roll 1 as the rolls rotate. Therefore, the dust such as the thread waste attached to the surface of the fabric 6 is attached to the surface of the adhesive roll 1 and the dust on the surface of the fabric 1 is removed. On the other hand, the dust adhered to the surface of the adhesive roll 1 is swollen by the hot water sprayed from the shower nozzle 2 for cleaning and heating, and the dust adhered to the surface of the adhesive roll 1 is apt to be removed from the surface of the adhesive roll 1. Since the surface of the adhesive roll is rubbed by the dust removing means 3, the dust on the surface of the adhesive roll 1 is separated from the surface of the roll. Thus, since the surface of the adhesive roll 1 from which dust has been removed is wet due to the adhesion of hot water from the cleaning shower nozzle 2, the adhesiveness of the adhesive roll 1 cannot be regenerated unless it is dried, so that the room temperature by the water draining means 4 is maintained. By blowing wind or hot air onto the surface of the pressure-sensitive adhesive roll 1 to drain water, the adhesiveness of the pressure-sensitive adhesive roll 1 is directly restored, and therefore dust on the surface of the fabric 6 that is continuously transferred is continuously and permanently removed. It is something.
The surface of the pressure-sensitive adhesive roll 1 is kept at a temperature of about 20 ° C to 40 ° C by hot water of 20 ° C to 40 ° C sprayed from the shower nozzle 2 or normal temperature air or hot air from the water draining means 4, and thereby the pressure sensitive adhesive is adhered. The surface adhesive force of the roll 1 has the effect of always being kept at an appropriate value.

[Outline of Invention]

As described above, the present invention, a pressure-sensitive adhesive roll that retains permanent adhesiveness, and a guide roll for guiding the continuously transferred object to be brought into contact with the pressure-sensitive adhesive surface of the pressure-sensitive adhesive roll,
In order to remove impurities adhering to the surface of the adhesive roll and to maintain the adhesiveness of the adhesive roll by heating, hot water spraying means for spraying hot water onto the surface of the adhesive roll, and the adhesive roll washed with hot water by this hot water spraying means A continuous cleaning device for a band-shaped product, characterized in that it is provided with a draining means for removing water on the surface.

〔The invention's effect〕

Therefore, according to the present invention, by continuously abutting the object to be treated on the adhesive surface of the adhesive roll that retains the permanent adhesiveness, the dust adhered to the surface of the object to be transferred is transferred. The impurities are transferred to the adhesive surface, whereby the impurities existing (adhered) on the entire surface of the object to be processed are continuously and effectively removed along with the continuous running operation of the object to be processed.

Further, in the present invention, the impurities transferred and adhered to the adhesive surface of the surface of the adhesive roll are continuously subjected to the jetting force of the hot water sprayed from the hot water spraying means, so that the impurities from the adhesive surface are generated by the thermal energy of the hot water. Since the adhesiveness of the surface of the adhesive roll is regenerated by the draining means by dropping and then blowing hot air, the object to be treated is continuously cleaned by continuously contacting the object with the surface of the adhesive roll. (Removal of thread waste, etc.) is effectively performed.
