Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a barrel cleaning device that uses an ultrasonic vibrator to improve cleaning efficiency of small objects to be cleaned.

[Conventional technology]

Generally, small metal parts etc. are stored, pickled,
The containers that are immersed in various liquid baths during the neutralization, plating, washing, and neutralization steps are called barrels, and a conventional barrel-based cleaning device is constructed as shown in FIG.

That is, in the figure, 1 is a barrel made of a hexagonal cylindrical box, 2 is an end plate on both end surfaces of the barrel 1,
3 is a rotating shaft attached to both end plates 2, 4 is a barrel 1
side plates parallel to the rotating shaft 3 forming the six sides of the hexagonal cylinder; 5 is a large number of small holes made through both end plates 2 and each side plate 4; 6 is a cleaning liquid; Two-thirds of the barrel 1 is immersed in the cleaning liquid 6, and objects to be cleaned, such as small metal parts, are accommodated in the barrel 1.

Reference numeral 7 denotes an ultrasonic transducer installed directly below the barrel 1, which irradiates the barrel 1 located directly above with ultrasonic waves, rotates the barrel 1 by rotating the rotating shaft 3 in one direction, and causes the inside of the barrel 1 to be rotated. The object to be cleaned is cleaned.

[Problem that the invention attempts to solve]

By the way, in the conventional device, the small hole 5 is 5 mm.
If the cleaning liquid 6 is in a state of
Ultrasonic waves are not transmitted to the object being cleaned inside.

In addition, since the ultrasonic vibrator 7 is installed directly below the barrel 1, the object to be cleaned moves as the barrel 1 rotates and is biased to one side of the barrel 1, ensuring that the ultrasonic waves are irradiated onto the object to be cleaned. The cleaning effect is poor.

[Means for solving problems]

This invention takes the above points into consideration and provides a barrel cleaning device with good cleaning effects, and includes a barrel in the form of a cylindrical box that accommodates small items to be cleaned and is immersed in a cleaning solution, and a distribution system for the cleaning solution. an end plate on both end surfaces of the barrel in which small holes are formed; a rotating shaft that is attached to the both end plates and rotates in one direction; This barrel cleaning device includes an ultrasonic vibrator that irradiates ultrasonic waves, which is placed close to an object, and a non-porous plate that is provided on the circumferential side of the barrel and transmits the ultrasonic waves.

[Effect]

Therefore, according to this invention, the circumferential side of the barrel that is irradiated with ultrasonic waves is non-porous, and there is no air film formed in the small pores as in the conventional case, so that the ultrasonic waves can reliably reach the object to be cleaned. Furthermore, since the ultrasonic transducer is installed close to the position where the object to be cleaned moves due to the rotation of the barrel, the ultrasonic waves can effectively reach the object to be cleaned. Irradiated and thoroughly cleaned.

〔Example〕

Next, this idea will be described in the second section showing one embodiment of the invention.
This will be explained in detail with reference to FIG.

In those drawings, the same signals as in FIG. 1 indicate the same things, and the difference is that the side plate 4 of the barrel 1
A non-porous cover plate 8 that transmits ultrasonic waves and covers the small holes 5 is provided, and the ultrasonic vibrator 7 is inserted from directly below the barrel 1 into the object 9 to be cleaned by rotating the barrel 1, as shown in FIG. The barrel 1 was moved and placed close to the offset position, and the barrel 1 was irradiated with ultrasonic waves from an oblique direction.

The cover plate 8 is made of hard vinyl chloride with a thickness of 5 to 10 mm because a soft material absorbs ultrasonic waves, and an excessively thick material prevents ultrasonic waves from passing through.

Note that a small hole 5 is formed in the end plate 2 of the barrel 1 so that the cleaning liquid and air can enter the inside of the barrel 1.

Therefore, according to the embodiment, since the circumferential side of the barrel 1 that is irradiated with ultrasonic waves is covered with the cover plate 8, an air film is not formed in the small hole unlike in the conventional case, and the The object to be cleaned 9 is irradiated with ultrasonic waves.

Further, the object to be cleaned 9 moves slightly to one side of the barrel 1 as the barrel 1 rotates, but since the ultrasonic vibrator 7 is provided close to the position where the object 9 is moved, The object to be cleaned 9 is effectively irradiated with ultrasonic waves.

In the above embodiment, the cover plate 8 was attached to cover the small hole 5 provided in the side plate 4 of the barrel 1 shown in FIG. Of course, it may be formed from a plate.

[Effect of idea]

As described above, according to the barrel cleaning device of this invention, a non-porous plate that transmits ultrasonic waves is provided on the circumferential side of the barrel where ultrasonic waves are irradiated. The ultrasonic wave is reliably irradiated onto the object to be cleaned, and the cleaning effect is great.

Furthermore, since the ultrasonic vibrator is provided close to the object to be cleaned which is moved and shifted due to the rotation of the barrel, the ultrasonic waves are effectively irradiated onto the object to be cleaned.
