Abstract

PROBLEM TO BE SOLVED: To remove a foreign matter sticking to a roller surface, and prevent the formation of a push flaw to a steel strip by forming a construction material of a foreign matter removing tip to contact with a roller out of nonwoven fabric or sponge. SOLUTION: A base stand 8 on which a foreign matter removing tip is installed, moves along guide rods 6 and 7 by driving of an air cylinder 4, and removes a foreign matter on a surface of a roller 2 to carry a steel strip 1. The foreign matter removing tip 3 is normally composed of nonwoven fabric or sponge, and adjusts push-pressing force to the roller by a push-pressing adjusting screw 5 of the tip. A rodless cylinder enclosing a magnet is used as the air cylinder. A case of using a soft raw material made of nonwoven fabric or sponge is when an object foreign matter is iron powder, a scale, waste yarn or the like, and there is no fear of flawing the roller since the raw material is soft, and it is used in such a feeling as wiping off the foreign matter.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll surface foreign matter removing device for removing foreign matter adhering to the surface of a transport roll in transporting a metal strip such as a steel strip.

[0002]

2. Description of the Related Art In transporting a metal strip such as a steel strip, if foreign matter adheres to the roll surface, a surface flaw is generated on the strip. Conventionally, by pressing a blade against the entire length of the roll, foreign matters such as iron powder, scale, and lint attached to the roll have been removed, thereby preventing the steel strip from being nicked. An apparatus for removing such foreign matter on the roll surface is disclosed in
There is an invention disclosed in Japanese Patent Application Laid-Open No. 4-46614. The present invention is an apparatus in which foreign matter can be removed by bringing a blade into contact with a roll.

[0003]

However, in the conventional blade as described above, the blade is pressed by the airbag because the blade is pressed by the airbag because the airbag swells or breaks due to aging. Disappears. In addition, since the blade is pressed over the entire length of the roll, a non-driven roll having a small winding angle of the strip becomes a resistance and hinders roll rotation. An object of the present invention is to provide an apparatus that solves such a drawback.

[0004]

According to the present invention, there is provided a roll surface foreign matter removing apparatus which reciprocates on a transport roll by driving a pneumatic cylinder to remove foreign matter adhering to the roll surface. A roll surface foreign matter removing device, wherein the material of the foreign matter removing chip in contact with the roll is a nonwoven fabric or a sponge. The portion that comes into contact with the roll is only the chip portion for removing foreign matter, and a small pressing force is required. Therefore, foreign matter can be effectively removed while reducing resistance to rotation of the transport roll.

[0005]

Embodiments of the present invention will now be described with reference to the drawings. 1 and 2 are a side view and a plan view, respectively, showing the apparatus of the present invention. A base 8 on which a foreign matter removing chip 3 is mounted moves along guide rods 6, 7 by driving a pneumatic cylinder 4. , And is configured to remove foreign matter on the surface of the roll 2 that transports the steel strip 1. The foreign matter removing tip 3 is usually made of a nonwoven fabric or a sponge, and the pressing force of the tip against the roll is adjusted by the pressing adjusting screw 5. The pneumatic cylinder uses a rodless cylinder with a built-in magnet.

Any material can be used as long as the chip is softer than the hardness of the roll. However, when a soft material made of non-woven fabric or sponge is used, foreign objects such as iron powder, scale, lint, etc. Since the material is soft, there is no need to worry about scratching the roll, and the material is used as if the foreign matter was wiped off.

[0007]

As described above, according to the roll surface foreign matter removing apparatus of the present invention, foreign matter adhering to the roll surface can be removed while securing the pressing force of the foreign matter removing tip without hindering the rotation of the transport roll. However, it is possible to prevent the steel strip from being nicked and improve the product quality.
