[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic plan view of a cleaning apparatus for explaining an embodiment of the present invention. The cleaning device is a housing 10.
A loading / unloading window 11 for the object to be cleaned is provided in which the rotating plate 12 and each cleaning process unit 13 are housed. The rotary plate 12 is slanted inward toward the inside and has a hole 14 in the central portion. Then, the cleaning unit 15 is detachably mounted on the plate surface of the first to fifth gutter-shaped holding portions 16 _(a to
_f) are provided radially. The cleaning tank unit 15 is the second
As shown in the figure, it is composed of, for example, a semicircular cylinder, and an ultrasonic wave generator 17 made of a piezoelectric material is attached to the outer surface thereof. It should be noted that both ends of the cylindrical body have mesh holes. The rotary plate 12 is, for example, an intermittent motor as a drive source (not shown).
As it is rotated intermittently. The cleaning process unit 13 includes various cleaning sources 13a and a drying source 13b. The cleaning source 13a stores each cleaning liquid such as city water, neutral cleaning liquid, first warm water, second warm water, etc. in each tank 18 _(a to _e) . And
Faucet (water inlet) 21 _(a to _d) controlled by solenoid valve 20
Have. The drying source 13b has a heater 19 provided with a warm air outlet 22. The faucet 21 and the hot air outlet 22 are provided on the rotary plate 1
Align on the outer circumference of 2. In this example, first, the tap 21a for city water is set on the left side of the carry-in / out window 11, and each faucet 21 is circulated counterclockwise, and finally the warm air port 22 is arranged on the right side of the carry-in / out window 11. In such a case, the plurality of cleaning tank units 15 accommodate the objects to be cleaned, for example, crystal pieces (not shown). Then, first, the first cleaning tank unit 15a is attached to the stopped first holding portion 16a in front of the carry-in / out window 11 (not shown, hereinafter the same). Then, the rotary plate 12 is rotated in the direction of the arrow, and the first to sixth holding portions 16 are rotated.
_(a to _d) are moved to the next cleaning process unit 13. The 1st holding part 16a stops before the tap 21a for city water, and the 2nd holding part 16b stops before the loading / unloading window 11. Then, each solenoid valve 20 is opened to allow each cleaning liquid to flow out. City water is supplied to the first cleaning tank unit 15a from one end side (upper end side) and naturally flows out from the other end side (lower end side). That is, the crystal piece in the tank is washed with tap water. Then, the solenoid valve is closed.
During this time, the second holding unit 16 moved in front of the loading / unloading window 11
The second cleaning tank unit 15b is attached to b. next,
The rotating plate 12 is rotated to move each holding unit 16 to the next cleaning process unit 13. That is, the first holding part 16a is moved to the neutral cleaning liquid faucet 21b, the second holding part 16b is moved to the city water faucet 21a, and the third holding part 16c is moved to the loading / unloading window 11. Then, each solenoid valve 20 is opened, and the first cleaning tank unit 15a is treated with a neutral cleaning solution to remove the second cleaning tank unit 15b.
Are washed with city water. Then, the third cleaning tank unit 15c is attached to the third holding portion 16c. The neutral cleaning liquid that has flown out from the other end of the cleaning tank unit 15 is collected in a tank by, for example, a pan, and circulated by the circulation mechanism such as the pump P and the filter F as described above. Also,
A replenishment tank 23 is connected to the tank 18b. In this way, each cleaning tank unit 15 is sequentially cleaned with city water, a neutral cleaning liquid, the first warm water, and the second warm water, starting from the mounting on the holding portion 16 from the carry-in / out window 11. Then, after being dried by the drying source 19, it returns to the front of the carry-in / out window 11 and is taken out from here.

With such a cleaning apparatus, with the cleaning tank unit 15 tilted, a clean cleaning liquid sufficiently purified by a filter or the like is supplied from one end side thereof and fed in one direction from the other end side. As outflow. Therefore, the cleaning liquid does not stay inside the cleaning tank unit 15, and a clean cleaning liquid always flows down. Therefore, dust and dirt adhering to the crystal piece, which is the object to be cleaned, is removed, and these are discharged together with the cleaning liquid from the other end side. That is, it is possible to prevent minute dust and the like from floating in the cleaning tank unit 15. For this reason, since the cleaning liquid is prevented from being contaminated in the cleaning tank unit 15, the crystal piece can be completely cleaned and the cleaning efficiency can be improved. Then, in this embodiment, the cleaning tank unit 15 is arranged on the rotary plate 12 and various kinds of cleaning are sequentially performed. Therefore, the cleaning device can be made compact as compared with the conventional vertically arranged cleaning devices, and the operator can place the cleaning tank unit 15 in front of the loading / unloading window 11.
Since it suffices to attach and remove the, the work efficiency is also improved.

[0009]

[Other Matters] In the above embodiment, a series of cleaning steps from the mounting of the cleaning tank unit 15 to the removal thereof are performed on the rotary plate 1.
Although it is completed by one round of 2, the carry-in / out window 11 may be provided on the opposite side to end the series of cleaning steps by half the circumference of the rotary plate 12. Further, the cleaning tank unit 15 may not necessarily be arranged (moved) radially on the rotary plate 12, but may be moved in one direction on a straight line, for example. In addition, the cleaning tank unit 15
Has a semi-cylindrical shape and has holes on both ends, but the cleaning liquid can sufficiently flow out without the holes, and is not an essential requirement.
Further, the shape is not limited to the semi-cylindrical shape, but may be a perfect cylindrical shape (however, in this case, holes for inflow and outflow of the cleaning liquid are required at both ends) or other rectangular cylindrical shape. Although the piezoelectric material is used as the ultrasonic wave generator 17 in the cleaning tank unit 15, other devices such as an air bubble generator may be used, and the ultrasonic wave generator 17 may be removed as necessary. Further, although the cleaning process is cleaning with city water, neutral cleaning liquid, first warm water, and second warm water and drying, it is needless to say that the cleaning process can be set according to the object to be cleaned. Further, it goes without saying that the moving (transferring) means of the cleaning tank unit 15 can be configured in any way based on a known technique. Although the rotary plate 123 is inclined inward, the cleaning tank unit 15 may be inclined even if it has a flat plate shape. Further, a trough-shaped groove inclined inward may be radially provided on the rotary plate 12 to allow each cleaning liquid to flow in and out, and for example, a mesh-shaped cleaning material container may be arranged therein. In this case, the trough-shaped groove itself is the cleaning tank unit 1
It becomes 5. In short, the present invention is basically intended to perform cleaning while allowing the cleaning liquid to flow into and out of the cylindrical cleaning tank unit 15 which moves in accordance with the cleaning process, and within a range not departing from this principle. Can be changed as desired.

[0010]

According to the present invention, since the cleaning liquid in the cleaning tank unit which moves according to the cleaning process is flowed as one-way flow from the inlet to the outlet, the object to be cleaned is cleaned, so that the cleaning liquid itself is sufficiently purified. It is possible to provide a fluid-type cleaning device capable of performing high-efficiency cleaning, and its practical value is very high.
