Description

[Detailed description of the invention] "Industrial application field" This invention relates to a car wash roller.

``Prior Technology'' Conventional car wash rollers were made of countless flexible synthetic resin long fibers embedded in the rotating shaft.
By increasing the rotating speed and slamming the long fibers against the car body, dirt and other adhering substances were separated and washed with water. Therefore, it is necessary to increase the rotation speed, and not only does the dirty water scatter, but it is difficult to wipe it off after cleaning. In particular, the long fibers were slammed against the car body, causing countless minute damage to the paint on the car body surface, which not only lost the luster of the surface, but also significantly reduced its anti-corrosion ability. In addition, a metal or synthetic resin plate knitted or molded into a fine polygon or circle is punched out in a circular outer circumference to form an elastic circular plate, and the same circular plate is used as a rotation shaft via a spacer with a diameter smaller than that of the circular plate. There is a supported roll brush, but the surface of the object to be polished is polished, ground, or cleaned by means of small protrusions formed on the outer periphery of the same circular plate, which are formed by the fine polygonal or circular punching. It causes countless minute damages to the paint on the body surface, loses the surface gloss, and significantly reduces the rust prevention ability. It was difficult to make surface contact following the unevenness of the surface. (Special Publication No. 52-113567).

"Problems to be Solved by the Invention" The object of the present invention is to carefully wipe off contaminants and wash water droplets on an uneven surface using a car wash roller.

``Means for Solving the Problems'' The present invention provides a method for attaching the center portions of a plurality of water-absorbing flexible sponge plates 2 having outer peripheries around a rotating shaft 1 to the rotating shaft 1 with an interval t in the axial direction. It is constituted by a car washing roller which is fixedly provided in the rotation direction and rotation direction, and the rotation shaft 1 is formed to be rotatable at low speed and high speed.

``Function'' Therefore, as shown in FIG. 6, the rotating shaft 1 is supported on the upper and both sides of the car wash machine 4, and when it is connected to a drive device and rotated at low speed, the sponge plate 2 absorbs water. The plate 2 also rotates around the rotation axis 1. When the car 5 is moved in this state,
The outer circumferential side surface of the sponge plate 2 slides on the surface of the vehicle body 6 to wet the same surface 6 and wipe off any adhering substances on the surface 6. After the car 5 leaves the sponge plate 2, the plate 2 is sprayed with water to clean it, and then the rotating shaft 1 is rapidly rotated to disperse (squeeze out) the moisture in the sponge plate 2 by centrifugal force. When the car 5 is dehydrated and the dehydrating sponge plate 2 is rotated at low speed and the car 5 is moved in the same manner as described above, the cleaning water droplets on the car body surface 6 are absorbed by the sponge plate 2 and can be wiped off with the same plate 2.

"Embodiment" To explain the embodiment of the present invention shown in the drawings, a plurality of water-absorbing flexible sponge plates 2 are rotated parallel to each other with an axial interval t on a rotation axis 1 in a horizontal or vertical direction. It is provided perpendicular to axis 1. The outer periphery of the sponge plate 2 is circular (Fig. 2,
(Fig. 3), rectangular (Fig. 4), or corrugated (Fig. 5), and are provided concentrically around the rotation axis 1.
The sponge plates 2 may be provided alternately obliquely, or may be provided spirally around the rotating shaft 1. When provided in a spiral, the pitch is the interval t. The sponge plate 2 is flexible and easy to bend, but is relatively strong and has a sufficient thickness to absorb water. The rotation shaft 1 is connected to a car wash machine 4 as shown in FIG.
It can be connected to a drive device (not shown) and rotated at low speed or high speed by a switching device. As shown in FIG. 6, the rotation shaft 1 is positioned so that the outer circumferential side surface of the sponge plate 2 comes into planar contact with the surface 6 of the car to be washed due to the centrifugal force caused by the low and high speed rotation of the sponge plate 2. The distance t is also maintained so that the planar contact portion is formed. In addition, what is shown by 3 in the figure is a cut portion.

The water-absorbing flexible sponge plate 2 is formed of a synthetic resin composite sheet that is integrally formed by sandwiching both sides of a synthetic resin net sheet with communicating hole sponge sheets made of hydrophilic synthetic resin, and is connected to a flange 7 provided on the rotation shaft 1. By fixing the center part of the sponge plate 2 with a bolt 8, the center part of the sponge plate 2 and the rotating shaft 1 are fixed in the axial direction and rotation direction. The spacing t between the sponge plates 2, 2 is determined by the relative distance between the rotating shaft 1 and the surface 6 of the car to be washed, as shown in FIG. 6, and the low rotational speed of the rotating shaft 1. It can be designed as appropriate to such an extent that the surface 6 is almost entirely covered by the planar contact portion on the outer periphery of the two.

"Effects" Since the present invention is configured as described above, the car wash roller adapts to the uneven surface 6 of the automobile 5 and sufficiently contacts the surface 6, and carefully wipes off adhering matter and water droplets without damaging the surface 6. I can do it.
