Description

[0001] DUST REMOVAL DEVICE OF WHEEL [0002]

The present invention relates to an apparatus for removing foreign materials on wheels.

In general, a caster is a wheel which is coupled to a lower side of a conveying device and can freely change its direction, and the caster is used in a place where it is used for various purposes or purposes.

In the case of a caster used outdoors, much foreign matter adheres to the outer circumferential surface of the wheel, and in the case of a caster used in a relatively clean room, a relatively small amount of foreign matter adheres to the outer circumferential surface of the wheel.

However, in the case of a caster which is used while going outdoors and indoors, since a lot of foreign substances outdoors are adhered to the outer circumferential surface of the wheel, it flows into the room and is used.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2007-0009213 discloses a technique of rotating a roll brush on a rotating arm and removing foreign matter adhered to the outer circumferential surface of the wheel.

However, the conventional casters are disadvantageous in that both ends of the shaft on which the roll brush is supported are inserted into the rotating arm and then fixed by fastening with a nut or the like.

In the conventional casters, since the roll brush is rotated by the rotation of the wheels, there is a problem that the foreign substances attached to the outer circumferential surface of the wheels can not be easily removed.

In addition, a conventional caster has a problem that a certain amount of foreign matter removed by the brush can not be collected by the collection box and is thrown to the ground.

In addition, the conventional caster can not keep the bristles in close contact with the wheel, so that the foreign matter on the surface of the wheel can not be easily removed.
