Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turntable cleaning device for spraying a cleaning liquid, for example, on an industrial metal part, particularly a flat object to be cleaned, which is rotated.

[0002]

2. Description of the Related Art Generally, as a cleaning method, there are a method using an organic solvent such as methylene chloride and a method using water or an aqueous cleaning solution. In the former method, the object to be cleaned was immersed in a bath of an organic solvent such as methylene chloride and cleaned by ultrasonic waves.However, the use of an organic solvent protects the environment and is harmful to the human body.
Due to work safety issues such as explosion risk, conversion to other cleaning methods was required.

On the other hand, the latter method using water or an aqueous cleaning solution includes an ultrasonic cleaning method and a spray cleaning method. In the ultrasonic cleaning method, when the object to be cleaned has a large diameter of, for example, about 1,500 mm, a large cleaning tank for accommodating the object is required, and a large ultrasonic transmitter is also required. There are many points.

In the spray cleaning method, it is necessary that a spray liquid flow of water or a water-based cleaning liquid directly hits the surface of the object to be cleaned to give an impact force, so that the flat object to be cleaned is held vertically to clean it. It is difficult to do, and it is often washed while installed horizontally. In this case, the cleaning liquid accumulates on the upper surface of the object to be cleaned in a film shape, and the impact force of the spray hardly reaches the object to be cleaned, so that the cleaning effect is low. For small objects to be cleaned, the rotation speed of the turntable on which they are mounted can be used to remove the cleaning liquid film on the surface of the object to be cleaned by centrifugal force. Rotating by means requires a large amount of power, is accompanied by danger, and is disadvantageous in that the device and mechanism are large in terms of strength of the turntable.

As means for removing the cleaning liquid from the object to be cleaned, in addition to the above, tilting the object to be cleaned, draining the object to be cleaned using a plastic or rubber scraper, wiper, brush or the like. Conceivable. But,
The method of (2) is poor in practicability because tilting a turntable on which a large object to be cleaned places a crane work for placing and lifting the object to be cleaned. Although it is possible to tilt the object to be cleaned in the cleaning tank, this causes an increase in cost. In addition, the method (1) is not practical because rubbing a scraper, a wiper, a brush or the like on the object to be cleaned after blasting causes the plastic and rubber to be scraped off, causing problems of abrasion and adhesion of shavings.

An object of the present invention is to provide a turntable cleaning device that overcomes all the above problems.

[0007] turntable cleaning apparatus according to the present invention, in the cleaning device for spraying a cleaning liquid thereto while rotating the plate-shaped object to be cleaned, the air blow nozzle header is provided in the upstream of the cleaning liquid spray nozzle header, the object to be cleaned The air blow nozzle header nozzle
Compressed air is ejected from the cleaning liquid film on the object to be cleaned.
Of the cleaning solution spray header on the exposed surface of the object to be cleaned.
The cleaning liquid is sprayed from the nozzle .

In a preferred embodiment of the above turntable cleaning apparatus, the cleaning liquid spray nozzle header has a required number of spray nozzles for spraying the cleaning liquid in a divergent manner, so that the cleaning liquid is applied to the entire surface of the object to be cleaned.

In another preferred embodiment, the cleaning liquid spray nozzle header has a required number of spray nozzles that move back and forth in the radial direction of the turntable and eject the cleaning liquid in a straight line, and the cleaning liquid is on the entire surface of the object to be cleaned. It is designed to hit.

In still another preferred example, the cleaning liquid spray nozzle header is moved back and forth in the radial direction of the turntable, has a required number of spray nozzles for spraying the cleaning liquid in a divergent manner, and sprays the cleaning liquid in a straight line. It has the required number of spray nozzles.

The tip of the air blow nozzle header is preferably bent in the wake direction near the center of the turntable.

The cleaning liquid spray nozzle header and the air blow nozzle header can be provided not only on the front side of the object to be cleaned but also on the back side as necessary.

[0013]

In the turntable cleaning device according to the present invention,
Since an air blow nozzle header is provided in the upstream of the cleaning liquid spray nozzle header, the cleaning liquid film on the cleaning target can be effectively removed to expose the surface of the cleaning target, and then the cleaning liquid can be sprayed on this exposed surface. Therefore, the cleaning effect can be enhanced.
