Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a friction cleaning method for cleaning the surface of a cylindrical or round object by rubbing it thereon.

Conventionally, for example, when cleaning the rotating drum of a trial copying machine, the cleaning was done by hand, but this was time consuming and had the disadvantage that the product could be uneven depending on the operator.

Another cleaning method was to put an ultrasonic vibrator in the cleaning solution and apply ultrasonic waves to the object to be cleaned, but the standing waves of the ultrasonic waves may cause uneven cleaning. However, especially when the object to be cleaned is a soft metal such as aluminum, there are drawbacks such as scratches on the surface of the object to be cleaned.

An object of the present invention is to provide a friction cleaning method that can uniformly clean objects to be cleaned without damaging them.

Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 show an embodiment of a rotary automatic friction cleaning device for carrying out the friction cleaning method of the present invention.

As shown in the figure, this apparatus has a cleaning tank 1 in which a high-speed rotating roller 2 and a low-speed rotating roller 3 are installed horizontally in parallel and adjacent to each other.

A rotating shaft 4 fixed to the center of these rollers 2 and 3,
5 is rotatably supported by the cleaning tank 1.

A small sprocket 6 and a large sprocket 7 are fixed to the tips of rotating shafts 4 and 5 that protrude outside the cleaning tank 1.

A drive shaft 8 driven by a rotational drive source such as a morph (not shown) is rotatably supported in the cleaning tank 1, and a pair of sprockets 9 are fixed to the drive shaft 8.

These sprockets 9 each sprocket 6゜7 mentioned above
It is connected with Cheno 10 and 11.

The cleaning tank 1 is filled with a cleaning liquid 12 so that the lower halves of the rotating rollers 2 and 3 are submerged.

The object to be cleaned 13 is placed on the cylindrical rotating rollers 2 and 3 astride them.

Next, a cleaning method using such an apparatus will be explained.

When a rotation drive source (not shown) is rotated, the low-speed rotating roller 2 and the high-speed rotating roller 3 rotate at different speeds.

When each of the rollers 2 and 3 rotates, the object to be cleaned 13 placed on them is also pressed against both rollers 2 and 3 by its own weight and rotates.

Since both rollers 2 and 3 are soaked in the cleaning liquid 12, the cleaning liquid 12 adheres to the surfaces of the rollers 2 and 3, and this liquid adheres to the object 13 to be cleaned.

The materials of the rollers 2 and 3 need to be changed depending on the object to be cleaned.

If the object to be cleaned is easily damaged, such as oil or sticky ink, use rollers 2 and 3.
It is necessary to form at least the surface of a ponge-like material, rubber, or cloth.

In addition, if the object to be cleaned is not easily damaged, use the rollers 2 and 3.
At least its surface is made of metal, wire mesh, etc.

The object to be cleaned 13 rotates at a rotation speed that follows the rotation speed of the high speed roller 2, which has a higher rotation speed.

Therefore, a difference in rotational speed occurs between the rotational speed of the object to be cleaned 13 and the rotational speed of the low-speed roller 3.

Due to this difference in rotation speed, the object to be cleaned 13 and the low-speed rotating roller 3
A frictional force is generated between the roller 3 and the object 1 to be cleaned.
The surface of the object 3 is rubbed, and the object 13 to be cleaned is uniformly cleaned in a short time due to the cleaning action of the cleaning liquid 12.

In the above embodiment, cleaning was performed by pouring the cleaning liquid 12 to a height that covered about half of each roller 2, 3, but as shown in FIG. Cleaning can also be performed by pouring the cleaning liquid 12 into the container.

In addition, in the above embodiment, one set of rollers 2 and 3 was set in the cleaning tank 1 for cleaning, but if multiple sets of rollers are set in the cleaning tank, a large number of objects to be cleaned can be cleaned at once. be able to.

Furthermore, in the above embodiment, the rotational force of the sprocket 9 is simultaneously transmitted to the sprockets 6 and 7, but in some cases, the rotational force of the sprocket 9 may be transmitted to one of the sprockets 1 to 6.
6, and the rotational force of the sprocket 6 may be transmitted to the other sprocket 7.

As explained above, in the present invention, a frictional force is generated between the object to be cleaned and the rollers due to the difference in the rotational speed of a pair of rollers on which the object to be cleaned is placed, and deposits on the surface of the object to be cleaned are removed by the rollers. Since it is removed by scrubbing, it can be cleaned evenly in a short time without much effort.
