Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ultrasonic cleaning device that prevents the object to be cleaned from being contaminated by the liquid used to clean the object.

Prior Art A conventional ultrasonic cleaning device has an ultrasonic vibrator installed at the bottom of a cleaning tank, moves a conveyor within the cleaning tank, and moves the object fixed to the conveyor within the liquid in the cleaning tank. I try to clean the items to be cleaned.

Problems to be Solved by the Invention However, in this conventional cleaning device, the liquid used to clean the object to be cleaned is constantly circulated and recovered, but while the object to be cleaned is being cleaned,
Since the object to be cleaned is always immersed in the cleaning liquid, when the object to be cleaned is pulled out of the cleaning tank, the dirt that has been removed from the object to be cleaned is suspended, and the floating dirt is returned to the object to be cleaned. There was a problem that the dirt was not completely removed from the object to be cleaned because of the adhesion.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an ultrasonic vibrator at the other end of the cover by narrowing one end to form a liquid spout, and introduces the liquid into the side surface of the cover. A plurality of ultrasonic pumps provided with ports are arranged side by side with the liquid spout at the top, and the object to be cleaned moving above the liquid spout is sprayed with liquid and ultrasonic waves to be cleaned. do.

Effect: According to the present invention, since the object to be cleaned moves above the liquid spout, liquid and ultrasonic waves are ejected from below to clean the object to be cleaned. Since the liquid that has been removed does not enter the liquid spout of the ultrasonic pump and falls down, dirt removed from the object to be cleaned does not adhere again, and a clean surface can be obtained.

Embodiments First, before describing embodiments of the present invention, the principle will be explained. The applicant has proposed an ultrasonic pump that ejects liquid using ultrasonic waves generated from an ultrasonic vibrator, as shown in Figure 1.
60-142982). In FIG. 1, one end of the cover 1 is narrowed to form a liquid spout 2, an ultrasonic vibrator 3 is provided at the other end of the cover, a liquid inlet 4 is provided on the side of the cover 1, and an ultrasonic wave An oscillator 5 is connected to the vibrator 3. Further, as shown in FIG. 2, the ultrasonic transducer 3 is mounted inside a case 6 with a flexible material such as sponge stuffed around it so that the generated vibrations are not transmitted to the outside. The case 6 on the side of the cover 1 is opened to expose the ultrasonic transducer 3 so that the ultrasonic waves generated from the ultrasonic wave 3 can be well transmitted into the cover 1.

In the ultrasonic pump 7 configured in this way, the third
As shown in the figure, the ultrasonic waves generated from the ultrasonic transducer 3 are reflected by the inner wall of the cover 1, and all of the ultrasonic waves are transmitted to the liquid jet outlet without a part of the ultrasonic waves returning to the direction of the ultrasonic transducer. Since the output is from 2, cover 1
When liquid is introduced from the liquid inlet 4, the fluid is efficiently ejected by the ultrasonic waves generated by the ultrasonic vibrator 3, and the ultrasonic waves are also emitted from the liquid ejecting port 2, so that the liquid is When sprayed onto the surface of the object to be cleaned, not only the liquid but also the dirt on the object to be cleaned is removed by the ultrasonic waves.

Fig. 4 is a front view of the ultrasonic cleaning device according to the first embodiment of the present invention, and Fig. 5 is a side view of the ultrasonic cleaning device of Fig. 4. The ultrasonic pump 7 is supported by a support 9 attached to a frame structure 8 so that the liquid jet port 2 faces upward, and an oscillation output is supplied from an oscillator 5 to each vibrator 3 of the ultrasonic pump 7. . Also ultrasonic pump 7
The liquid inlet 4 is connected to a pipe 10 that is connected to a tank (not shown) containing a cleaning liquid.
Further, the rotating shafts 1 of the rotating rolls at both ends that rotate the belt 13 of the belt conveyor 12 are mounted on bearings 11 supported by the upper frame 8 of the ultrasonic pump 7.
4 and 15 are supported, and the pulley 16 that rotates this rotating shaft 14 is driven by another motor (not shown).
etc. via a belt. The object 17 to be cleaned is mounted on the belt 13 of the belt conveyor 12, and is configured to move above the ultrasonic pump 7.

In the ultrasonic cleaning apparatus of this embodiment configured as described above, when the belt conveyor 12 is driven and the object to be cleaned 17 moves above the ultrasonic pump 7, liquid and Ultrasonic waves are ejected toward the object 17 to be cleaned, and the object 17 to be cleaned is
is cleaned using liquid and ultrasound. The liquid that becomes dirty after washing the object to be cleaned 17 immediately falls and is collected in a lower container (not shown), so that the object to be cleaned is not immersed in the liquid that has been contaminated with dirt, and the liquid that has become contaminated with dirt can be prevented. It is possible to avoid contaminating the object to be cleaned again with the dirt that has been removed.

Structure, 9 is a support, 10 is a pipe, 11 is a bearing, 12 is a belt conveyor, 13 is a belt, 1
4 and 15 are rotating shafts, 16 is a pulley, and 17 is an object to be cleaned.Since these structures are the same as the embodiment shown in FIG. Support body 9 that supports the sonic pump 7
is configured to slide in a direction perpendicular to the traveling direction of the belt 13 of the belt conveyor 12 by a sliding structure 18 provided on the frame body 8. The support body 9 is connected to a reciprocating device 20 via a drive shaft 19, and is configured to reciprocate in a direction perpendicular to the traveling direction of the belt 13.

In the ultrasonic cleaning apparatus of this embodiment configured in this way, the ultrasonic pump 7 reciprocates at right angles to the traveling direction of the belt 13 of the belt conveyor 12.
Since the liquid and ultrasonic waves ejected from the ultrasonic pump 7 hit the entire object 17 to be cleaned, there is an advantage that uneven cleaning is eliminated.

Effects of the invention As is clear from the above explanation, in the present invention, the liquid jet port of the ultrasonic pump is directed upward to move the object to be cleaned, so that the liquid jetted from the jet port of the ultrasonic pump is The object to be cleaned has the advantage that almost no dirt adheres to it because it falls immediately after it hits the object to be cleaned and is not immersed in the cleaning liquid mixed with dirt. By attaching the sonic pump to the object to be cleaned and moving it back and forth in the right angle direction, or by shifting the position of the ultrasonic pump and supporting it, there is an advantage that uneven cleaning of the object supported by the belt conveyor can be eliminated. be.
