Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an ultrasonic cleaning device configured to perform ultrasonic cleaning while rotating an object to be cleaned in a cleaning tank.

(Prior Art) As the ultrasonic cleaning device, for example, Japanese Utility Model Publication No. 51-52
As disclosed in Japanese Patent No. 226, a jig for mounting an object to be cleaned, which is rotationally driven by an external power, is supported in a cleaning tank equipped with an ultrasonic wave generator, and the object to be cleaned attached to the jig is rotated. There is known a device configured to perform ultrasonic cleaning while being driven.

(Problems to be Solved by the Invention) In the above-mentioned conventional apparatus, it is possible to uniformly apply ultrasonic waves to the entire circumference by rotating the object to be cleaned around a constant axis. However, there is a problem in that the cleaning efficiency is poor because the cleaning can be performed only one by one. It is conceivable to provide a plurality of jigs for mounting the objects to be cleaned and to wash a plurality of objects to be cleaned at one time. Was not practical because the arriving ultrasonic waves were attenuated and the ultrasonic waves were blocked by other objects to be cleaned, so that the cleaning could not be sufficiently performed.

The present invention has been made paying attention to such a point, and an object thereof is to improve cleaning performance by improving the rotating structure of the jig.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a jig holder rotatably inside a cleaning tank equipped with an ultrasonic wave generator and eccentricity of the jig holder. At the position, a plurality of jigs for supporting the object to be cleaned are rotatably supported, and each of the first gears connected to each of the rotary support shafts to which these jigs are attached is fixed to the cleaning tank side and fixed. The jig is configured to be engaged with a second gear that is arranged concentrically with the rotation axis of the tool holder, and each jig rotates in synchronization with the rotation of the jig holder.

(Operation) According to the above configuration, each of the objects to be cleaned attached to each jig is ultrasonically cleaned while revolving in addition to rotating, and each is subjected to the effect of ultrasonic waves on the entire circumference under the same conditions. Be washed.

(Example) The Example of this invention is described with reference to drawings. FIG. 1 is a sectional view showing the overall configuration of an ultrasonic cleaning device.

In the figure, reference numeral 1 is a cleaning tank in which the cleaning liquid 2 is stored up to a predetermined level, and an ultrasonic wave generator 3 is provided on the bottom surface thereof. The object W to be cleaned is formed by winding a wire 5 around a round bar 4 in a coil shape. A mechanism for horizontally supporting a plurality of objects W to be cleaned and revolving and rotating is provided in the cleaning tank 1.

Disc-shaped jig holders 6 and 6 are rotatably supported on opposing vertical walls 1a and 1b of the cleaning tank 1 about a common horizontal axis P, and each jig holder 6 and A plurality of pairs of jigs 7, 7 for attaching an object to be cleaned are rotatably attached at positions eccentric from the rotation axis P at equal intervals in the circumferential direction via rotation support shafts 8, 8.

An opening toward the center of the tank is formed in the jig 7, and a receiving metal 9 for supporting the object to be cleaned and a coil spring 10 for biasing this to the front are incorporated therein, and the jig 7 is A ring-shaped backing plate 11 having a hole 21 for inserting an article to be cleaned is attached to the tip end thereof, and the receiving metal 9 is prevented from coming out.

When the object W to be cleaned is mounted on the pair of jigs 7 having the above-described structure, first, one end of the object W to be cleaned is attached to the jig 7 on one side.
After being inserted deeply into the jig 7, the other end is inserted into the other jig 7, so that the object W to be cleaned is horizontally supported by being elastically sandwiched between the receiving metal fittings 9, 9 as shown in the figure. It Also,
Removal of the object W to be cleaned is carried out by reversing the above operation.
It is possible to easily attach and remove the object W to be cleaned without using a tool.

The jig 7 on the right side is revolved and rotated by the following structure.

The jig holder 6 on the right side is rotatably loosely fitted and supported on the front end side of a fixed support shaft 13 which is cantilevered horizontally on the vertical wall portion 1a via a boss 12, and the jig 7 is fixed on one end thereof. Each of the small diameter first gears 14 is connected and fixed to the other end of the support shaft 8.

The first gear 14 is provided on the base side of the fixed support shaft 14.
A large-diameter second gear 15 having an inner tooth 15a that meshes with is rotatably loosely fitted, and a central gear 1 that meshes with each of the first gears 14 between the jig holder 6 and the second gear 15.
6 is connected and fixed to the fixed support shaft 13.

The second gear 15 is formed with external teeth 15b, and the drive pinion gear 17 is engaged with the external teeth 15b. The drive pinion gear 17 is mounted on a drive shaft 19 which is horizontally supported by the vertical wall portion 1a and interlocked with a motor 18 outside the tank so as to be integrally rotatable and shiftable via a key or a spline, and It is biased to one side by the spring 20, and is normally engaged with the external tooth 15b.

According to the above configuration, by driving the motor 18 and rotating the second gear 15 by the drive pinion gear 17, each of the first gears 15 revolves around the center gear 16 while rotating on its own axis. Therefore, the jig 7 rotates while the jig holder 6 rotates. Further, the jig holder 6 and the jig 7 on the left side are revolved and revolved following those on the right side via the article W to be cleaned.

Here, the liquid level of the cleaning liquid 2 is set to a level lower than that of the jig 7 that has reached the highest position, and the object W to be cleaned is repeatedly taken in and out of the cleaning liquid 2 to be contaminated. It is easily discharged from the surface of the cleaning object W.

Further, the object to be cleaned W can be attached to or taken out from the jig 7 exposed on the liquid surface without extracting the cleaning liquid 2.

Further, by shifting the drive pinion gear 17 against the spring 20 and removing it from the outer teeth 15b of the second gear 15, the jig holder 6 can be freely rotated even during cleaning, and the jig holder 6 can be manually rotated. While doing so, the object W to be cleaned can be attached / detached to / from each jig 7. In addition, when the jig holder 6 is freely rotated as described above, during cleaning,
It is possible to visually inspect the cleaning state of the object to be cleaned while rotating the jig holder 6 by hand during non-cleaning.

(Effect of the Invention) As described above, according to the present invention, the plurality of jigs supporting the object to be cleaned are revolved and rotated, so that ultrasonic waves are applied to each object to be cleaned from the entire circumference under the same conditions. As a result, it is possible to efficiently operate, and thereby, it is possible to simultaneously clean a plurality of objects to be cleaned, the cleaning performance is improved as a whole, and the processing time can be shortened.
