A rotary shaft 18 rotatably supported by a bearing 17 fixed to the upper plate 2a of the pedestal 2 passes through the center of the main container 3 to connect the two. It protrudes above the plate 16. A motor 2) for driving the rotating shaft 18 is attached to the upper plate 2a of the pedestal 2 via a pair of reduction gears 19 and 20, and a motor 2) is attached to the upper end of the rotating shaft 18. A base end portion of an arm member 23 is connected to the shaped bracket 22, and the distal end portion of the arm member 23 is bifurcated, and a cleaning hopper 24 is attached to this distal end portion.

Further, as shown in FIG. 3, the arm member 23 has a base end pivotally connected to the bracket 22 via a pin 25 so as to be able to swing up and down. is equipped with a roller 26, and a ring-shaped cam member 27 centered on the rotating shaft 18 is fixed on the upper surface of the connecting plate 16. A roller 26 is mounted. As a result, when the arm member 23 rotates together with the rotating shaft 18,
The arm member 23 swings up and down according to the irregularities on the cam surface 27a of the cam member 27, and the cleaning hopper 24 moves up and down while rotating accordingly.

Further, as shown in FIG. 3.4, the washing hopper 24 is supported via a square frame-shaped main body 28 and a pair of bin members 29, 29 on both left and right sides of the open bottom of the main body 28. A pair of gate members 30.30 that open and close the bottom of the main body 28 by swinging up and down, and the gate member 3
It consists of a link mechanism that drives 0.30. This link mechanism includes a pair of link members 32, one end of which is pivotally connected to bracket portions 30a, 30a integrally formed with the pair of games 30, 30, respectively, and the other end of which is connected to each other via a connecting member 31. , 32, and a spring 34 is installed between the connecting member 31 and a blade throat 33 fixed to the upper part of the hopper body 28, and the upward biasing force of this spring 34 normally Link member 32.3 as shown in solid line in FIG.

The gate member 30.30 is prevented from opening due to the weight of the article to be cleaned that acts on the gate member 30.30, the impact when the article is thrown in, etc. In addition, the cleaning hopper 24
The main body 28 and the gate member 30.30 are formed of perforated plates, so that when the hopper 24 is immersed in the cleaning liquid, the cleaning liquid flows therein.

Further, as shown in FIG. 1, the cover 4 is provided with an article input port 37 corresponding to the article input position of the cleaning hopper 24 shown by a solid line C in FIG. A temporary storage chamber 38 for articles is provided above.

An auxiliary cover 39 is provided to cover the opening at the upper end of the storage chamber 38, and a shutter member 40 is provided at the article input port 37 at the bottom of the storage chamber 38. As shown in FIG. 5, this shutter member 40 has one end attached to the center of the cover 4 by a pin member 41 so as to be rotatable along the lower surface of the cover 4, and is held in place by a spring 42. The end of rotation is regulated by a stopper 43, and the article input port 37 in the cover 4 is closed at the regulated position. As shown by the chain line in FIG. 5, when the washing hopper 24 is rotated to the article loading position, a predetermined position of the hopper 24 or the arm member 23 comes into contact with the shutter member 40, so that the arm The shutter member 40 is rotated to open the input port 37 by the rotation of the member 23 or the cleaning hopper 24, so that the articles in the storage chamber 38 are loaded into the cleaning hopper 24. . Note that the washing hopper 24 or the arm member 23 is lowered past the article loading position, so that the hopper 24 or the arm member 23 and the shutter member 40 are lowered.
When the shutter member 40 is released from contact with the shutter member 40, the spring 42 returns the shutter member 40 to the position where it closes the input port 37.

Here, the lifting and lowering operations of the cleaning hopper 24 with respect to the rotation angle will be explained using the lift line section of the cam member 27 shown in FIG. When it rotates from that position to the high-temperature cleaning section 8, it descends, and then rises once more, and then
It descends again in the low-temperature cleaning section 9. Then, after rising again, the steam cleaning section 10 lowers by a slight amount, and then returns from the article discharge position to the input position while maintaining the high position state. In that case, as indicated by the reference numeral in FIG.
Immediately after passing through the input position, the shutter member 40 is lowered by a predetermined amount to return the shutter member 40 to the position where the input port 37 is closed as described above, and the high temperature cleaning section 8, low temperature cleaning section 9 and steam cleaning In part 10, the lowering part of the cam lift is 2)! The cleaning hopper 24 is vibrated up and down as it passes through each of these locations.

Next, the operation of this cleaning device 1 will be described. First, a predetermined amount of articles to be cleaned is put into a temporary storage chamber 38 provided in the cover 4, and the upper part of the chamber 38 is closed with an auxiliary cover 39. A pair of reduction gears 19.20 are then driven by the motor 2).
Washing hopper 24 via rotary shaft 18 and arm member 23
When the hopper 24 reaches the article loading position, the shutter member 40 provided at the bottom of the storage chamber 38 is opened. , when the article input port 37 is opened, the storage chamber 38 is opened.
The articles inside will be thrown into the washing hopper 24 located below. In this case, even if the shutter member 40 is opened when the article is inserted, the upper part of the storage chamber 38 is closed by the auxiliary cover 39, and the auxiliary cover 39 is opened to supply the article to the temporary storage chamber 38. In either case, since the shutter member 40 is closed, the vapor of the cleaning liquid does not flow out from the main body container 3 to the outside.

When the article is put into the washing hopper 24 as described above, the article is moved by the rotation of the washing hopper 24.
First, it is supplied to the high-temperature cleaning section 8 , where the cleaning hopper 24 is lowered to be immersed in the high-temperature cleaning liquid stored in the cleaning section 8 . Then, by vibrating the cleaning hopper 24 within this cleaning liquid, the article can be efficiently cleaned at high temperature.

Next, after the cleaning hopper 24 rises once, the low temperature cleaning section 9
The articles in the hopper 24 are immersed in the low-temperature cleaning liquid stored in the low-temperature cleaning section, and the cleaning hopper 24 also vibrates. Low-temperature cleaning of the articles in the hopper 24 can be performed satisfactorily.

Furthermore, after the cleaning hopper 24 rises again, it rotates to the steam cleaning section 10, but since this steam cleaning section 10 is filled with the steam of the cleaning liquid, the articles in the cleaning hopper 24 are cleaned by this steam. That will happen. In this case, the cleaning hopper 24 also vibrates in the steam cleaning section 10, so that steam cleaning can be performed satisfactorily. Note that this steam cleaning section 10 communicates with the high temperature cleaning section 9 via the communication section 11, so the cleaning liquid is stored to the same level as the high temperature cleaning section 9, but in this steam cleaning section 10, Since the cleaning hopper 24 only vibrates and hardly descends, the articles are not immersed in the cleaning liquid. Also, since the heater 12 that heats the cleaning liquid is disposed in the steam cleaning section 10, the steam is mainly absorbed by this steam. The steam cleaning section 10 is filled with the steam, and in this way, one heater 12 can perform both cleaning with the high temperature cleaning liquid and its steam effectively.

Thereafter, the washing hopper 24 rotates to the article discharge position, and at this position, the roller 35 of the link mechanism in the hopper 24 is pushed down by the push-down member 36.
By opening and moving the pair of gate members 30°30,
The articles in the hopper 24 are discharged onto the inclined perforated plate below, and further taken out from the discharge gate 14 on the side surface of the main container 3.

In this way, the article is subjected to high-temperature cleaning, low-temperature cleaning and steam cleaning, and the article is well cleaned. During the cleaning in each section 8.9.10 above, the following articles are If it is supplied to the temporary storage chamber 38, the above-mentioned cleaning operation can be performed continuously on a large number of articles.

In addition, in this embodiment, as shown in FIG.
Since it is #-shaped, it is possible to have two or four arm members 23 or cleaning hoppers 24, thereby making it possible to improve the efficiency of cleaning work.

(Effects of the Invention) As described above, according to the present invention, articles to be cleaned can be sequentially and continuously supplied to a plurality of cleaning sections by rotating and raising/lowering the cleaning hopper by one driving means. As a result, a cleaning device of this type that is extremely compact and has a simple configuration can be realized. Particularly, according to the second aspect of the invention, when the article to be cleaned is supplied, the main container in which the cleaning liquid is stored does not communicate with the outside, so that the air is not contaminated by the vapor of the cleaning liquid, and therefore, the cleaning liquid can be cleaned easily. A safe environment will be maintained. Also, the third
, 4 According to the invention, when performing cleaning by the multiple liquid phase-vapor phase method, heating of the cleaning liquid in the high temperature cleaning section and generation of cleaning liquid vapor used for steam cleaning are performed by one heater, and thereby, The configuration of the cleaning device is further simplified. Note that the present invention is applicable not only to the case where the above-mentioned trichlorethylene or the like is used as the cleaning liquid, but also to the case where a water-soluble detergent is used.
