DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is attached to the rotating body
The present invention relates to a cleaning body of a cleaning apparatus for cleaning a surface of a vehicle body by bringing the cleaning body into contact with the surface of the vehicle body.

[0002]

2. Description of the Related Art A car washing apparatus is well known in the art without mentioning a document name, and is generally constructed as follows. That is, the main component is a gate-shaped traveling frame that reciprocates on a traveling rail laid on the floor surface, and the traveling frame includes a top brush, rotating brushes such as side brushes, water,
Various nozzles for injecting detergent, wax, etc., a blower device for drying, a control device, and the like are mounted. Therefore, it is possible to use these devices to automatically clean the surface of a car, but in particular, rotate the rotating brush while contacting the surface of the car body to remove mud, sand, etc. adhering to the car body surface. Can be washed off. By the way, the rotating brush provided and implemented in the above-described car washing apparatus is formed of brush bristles as is well known. The brush bristles are generally formed from a resin such as polyethylene.
Such a rotating brush made of a synthetic resin has various advantages and has been used for many years. For example, the amount of adsorbed water is small, the weight does not increase more than necessary, and there is no fear of freezing. In addition, by changing the material or size of the brush bristles, the tensile strength can be adjusted, so that when the brush bristles are caught on projections of the vehicle during car washing, only the caught brush bristles are cut off, There are advantages such as protection of projections of the vehicle and prevention of excessive force acting on the rotating brush device itself.

[0003] However, there is also a problem with the rotating brush device composed of brush bristles. For example, brush bristles are made of a soft resin such as polyethylene, but during car washing, centrifugal force is generated due to rotational force, and the tips of the brush bristles are hit against the surface of the vehicle body, and the physical Since it is washed by the action, mud, sand and the like are rubbed against the painted surface of the vehicle, which may damage the painted surface.
Originally, the purpose of cleaning a vehicle is to remove dirt attached to the surface of the vehicle, but the problem of "car wash scratches" accompanies the removal operation. The main substances of vehicle surface dirt are mud, sand,
These substances include carbon and the like, and some of these substances include substances that are harder than the painted surface of the vehicle. This means that cleaning with the physical impact of brush bristles will cause scarring on the painted surface of the vehicle. Even when brushing while releasing mud, sand, etc. with water, detergent, etc., the released mud, sand, etc. are physically beaten by brush bristles on the painted surface of the vehicle and agitated, so it is similar to the painted surface There is still the danger of getting scratched.

Therefore, a rotating brush made of a woven fabric or a non-woven fabric has been proposed in, for example, Japanese Utility Model Laid-Open No. 61-177958 and Japanese Utility Model Laid-Open No. 61-181527. Japanese Utility Model Application Laid-Open No. 61-177958 discloses a car wash brush provided with a reinforcing core in a fiber sheet. Therefore, the surface of the vehicle body can be washed by rotating the car wash brush. Japanese Utility Model Application Laid-Open No. 61-181527 discloses a car wash brush in which a plurality of flexible brushes are attached around a rotating shaft via an attachment. The car wash brush can also drive the rotating shaft to wash the car.

[0005]

The above-mentioned car wash brush also has
Since the material that comes into contact with the vehicle surface during car washing is formed of flexible fibers, protection of the painted surface during car washing can be expected to some extent as compared with synthetic resin brush bristles. In addition, since the reinforcing core is inserted or attached via a fixture, a certain degree of rigidity is obtained, and the car wash brush may not be attached to the rotating body during car wash. However, from the conventional woven or non-woven fabric described above,
The cleaning body that is torn will break and protrude during cleaning, e.g.
Catch on the back-up mirror, etc., and damage these projections.
There is a problem that there is a risk that The present invention has been made in view of the conventional problems described above, without damaging the painted surface of the vehicle during cleaning, the cleaning of the resolved vehicle washing apparatus corruption problems projections or the like of the vehicle It is intended to provide.

[0006]

According to the present invention, there is provided a cleaning device for a cleaning apparatus, which is mounted on a rotating body and contacts a surface of the vehicle body to clean the surface of the vehicle body. The cleaning body is made of a long-fiber nonwoven fabric.

Is the length L of the long side as shown in FIG.
Has a rectangular shape with a width W of 600 to 1000 mm and a short side width W of about 60 mm. Cuts 3, 3,... Having a depth of about 80 mm are made in both ends 2, 2. At substantially the center of the cleaning body 1, mounting holes 4 are provided, and the right half including the mounting holes 4 is the first portion 1.
A, the left half is the second portion 2A. A central portion or a fixed portion side portion 5 having a predetermined length around the holes 4 is treated with a synthetic resin such as a melamine resin, an acrylic resin, or a fluororesin. This synthetic resin treatment can be performed in various forms. For example, both surfaces of the fixed portion side portion 5 can be coated with a synthetic resin. At this time, the coating is performed using the mounting holes 4, 4
Is desirably thickened in the vicinity of and gradually thinned toward the tips 2 and 2. This is because the change in rigidity becomes smooth.
Further, only one surface of the fixed portion side portion 5 can be coated. Furthermore, instead of coating,
The resin may be impregnated as described above. Also at this time, the impregnation amount can be varied in the length direction.

In this embodiment, a pipe made of vinyl chloride resin, that is, a PVC pipe 10 is used as a rotating body for mounting the cleaning body 1, and its diameter is selected to be about 100 mm. A plurality of the above-mentioned cleaning bodies 1 are prepared, and round screws 11, 11 are provided around the PVC pipe 10 in the mounting holes 4, 4.
