If Freon or chloroethane is used as a cleaning liquid, most dirt can be cleaned cleanly, but there is a problem of environmental destruction such as destruction of the ozone layer. Therefore, it has been required to wash various articles with a washing solution of a degree to which a neutral detergent is added to water.
Oil stains or the like adhering to the inside of the parts and the return box during processing or storage of parts should be washed by shaking the object to be washed in detergent water, or by rinsing or spraying detergent water onto the object to be washed. Can be. However, due to long-term use, dirt such as stains and soot adhering to the outer surface of the shipping box and the surface becoming darkened can be cleaned simply by shaking in detergent water or spraying detergent water. Can not do it. Such dirt cannot be removed unless it is rubbed several times with a brush soaked in detergent water, and if it is to be cleaned manually, the work time and work load are very large and cost enormous. In addition, if the machine is to be machined, a machine having a complicated structure for moving the brush according to the shape of the object to be cleaned must be individually manufactured, and the equipment cost becomes extremely large.

The washing liquid is preferably water or water to which a neutral detergent is added (in this specification, detergent water is used inclusive of both).
Is used, but this does not prevent the use of other cleaning liquids. Since the present invention provides a large cleaning action by the physical action of rubbing or collision, it is possible to use the method of the present invention in combination with a cleaning method utilizing a chemical action peculiar to the cleaning liquid. Of course, a higher cleaning effect can be obtained. The detergent water can be heated and used if necessary. The chemical action of the detergent and the action of dissolving the soil with water increase with increasing temperature and thus the cleaning effect.

The particle size and hardness of the granular material should be determined according to the shape of the object to be cleaned and the type of dirt, but are particles having a hardness of about a soft or hard synthetic resin, and generally a grain of rice or sand. Particle sizes are used. A typical example of a practical granular material is a synthetic resin pellet which is a raw material before molding of a plastic product. It is effective to use polyethylene or polypropylene pellets in terms of price and specific gravity. It is of course possible to use a single cylindrical pellet of this kind, but if a pellet extruded into a square or star shape is used, the cleaning effect can be further enhanced.

The repetitive motion is generally a rotary motion, a turning motion or a linear reciprocating motion. By combining these, complicated movements in various directions can be performed. The cleaning action in the method of the present invention is caused by the particles 2 of the particle layer 3 floating on the upper layer of the cleaning liquid rubbing or colliding with the surface of the moving object to be cleaned.
Moving the object to be cleaned slowly has no effect. It is preferable to move while changing the moving direction at a somewhat high speed. Since the turning motion can be changed mechanically in all directions and is easily realized mechanically, when cleaning the surface of the box 4 having vertical and horizontal flanges on the surface, the surface and corners of the flange also have a single rotation. This is advantageous because it can be washed by exercise.
If the surface of the object to be cleaned has a flange or irregularities, if the direction and form of the reciprocating movement can be changed so that the optimum cleaning effect can be obtained, the mechanical structure becomes complicated. Thus, more efficient cleaning can be performed.

The object-to-be-cleaned holding means 6 is to grip the object to be cleaned 4 from the outside or the inside, to provide a clamp for holding a flange or the like of the object to be cleaned, and to bind the object to be cleaned with a belt-shaped object. The object to be cleaned 4 is held by such means. The object-to-be-cleaned holding means 6 lifts and lowers the object-to-be-cleaned above the cleaning tank 5 or positions it in the granular material layer 3. The drive mechanism 7 rotates or reciprocates the object-to-be-cleaned 6 in a horizontal plane in a state where the surface 4a of the object to be cleaned is positioned on the granular material layer 3, thereby cleaning the object in the presence of the cleaning liquid 1. The cleaning is performed by rubbing the surface 4a to be formed with the granular material 2. The rotating device 8 rotates the object-to-be-cleaned holding means 6 by a predetermined angle so that the surface 4 to be cleaned is cooperated with the elevating device 9.

When the object to be cleaned 4 is lowered into the cleaning liquid having the granular material layer 3 formed thereon, the granular material 2 is pushed down by the surface to be cleaned, so that the granular material 2 attempts to be cleaned by buoyancy. It is pressed against the surface 4a. 5A shows a state in which the granular material 2 is pressed against the lower outer surface of the object 4 to be cleaned, and FIG. 5B shows a state in which the granular material 2 is pressed against the upper inner surface of the object 4 to be cleaned. Is shown. The gap between the granular materials of the granular material layer 3 is filled with the cleaning liquid. In this state, by repeatedly moving the object 4 to be cleaned,
The granular material 2 is rubbed against the surface 4a of the object to be cleaned wet with the cleaning liquid, and the dirt stuck to the surface is cleaned as if rubbed with a brush. Since the granular material 2 is pressed against the cleaning surface 4a of the object to be cleaned by buoyancy,
The surface to be cleaned is in a complicated shape because it comes into contact with the object to be cleaned with a substantially constant force following the unevenness of the surface to be cleaned, and is rubbed in any direction required by the movement of the object to be cleaned. The cleaning can be performed uniformly and efficiently.

Further, when the object 4 to be cleaned is moved in a region including the granular material layer 3 such as rotation or repetitive movement, a wavy motion occurs in the upper layer of the cleaning liquid 1, and the granular material 2 is moved by the wave. The rubbing and collision are repeated on the outer surface of the cleaning object 4 from various directions and in a range not less than the depth of the granular material layer 3, and the cleaning can be performed by the physical action. FIG. 4 schematically illustrates this cleaning method.

When synthetic resin pellets are used as the granular material, a phenomenon occurs in which the granular material adheres to the surface of the washed object after the washing is completed. This can be washed off by sucking a lower cleaning liquid (hence no particulate matter) by a pump and flowing it from above the object to be cleaned. Furthermore, if the rinsing liquid overflows in the rinsing tank and the particulate matter flowing along with the running water is captured and reused by a filter or the like, the loss of the particulate matter due to adhesion to the object to be cleaned is almost completely eliminated. Can be avoided.
