An arm 72 is attached to the square shaft 87 on the opposite side to the side on which the gear 19 is attached, protruding from the rotating cylinder 17 on both sides.
73 is fixed with a nut (not shown), and the switching valve 74 is fixed by being centered directly below the center of the rotating cylinder 17 and horizontally abutting against the inner surface of the lid 7, and the switching valve 74 is operated. The pins 76 and 77 fixed to the left and right ends of the rod 75 are attached to the arm 7, respectively.
It is designed so that it can come into contact with 2 and 73. The switching valve 74 has a cylinder body formed by a main body 74a and a lid 86, and the valve 78 is connected to the main body 74a via O-rings 81 and 82.
It is embedded in An operating rod 75 with bolts 76 and 77 screwed into both ends slides into the center hole of a valve 78, and a compression spring 79 is inserted into the operating rod between the bolts 76 and the valve 78, and between the valve 78 and the bolt 77. , 80 have the same dimensions and the same performance. The center hole 86a of the lid 86 and the hole 74b opposite thereto are round holes that are spaced apart from the compression springs 79, 80 but are smaller than the outer diameter of the pads 76, 77. The distance between air ports 83 and 84 is O-ring 8
The spacing is equal to 1.82.

Next, the effect will be explained. In Figure 6, the swing angle θ
The arms 72, 73 rotate counterclockwise or clockwise. For example, when the arm 72 begins to push the stopper 76 of the operating rod 75 counterclockwise from a position α before the end of the swing angle θ, the compression spring 80 inserted into the operating rod 75 will move to the compression spring on the right side of FIG. If the repulsive force stored in the compressed compression spring 80 that is gradually contracted from the fully extended position like 79 overcomes the static frictional force of the valve 78 that airtightly moves left and right on the inner surface of the cylinder of the switching valve 74, the valve will open. The arm 78 is started to be moved rightward from the left end position, and by the time the arm 72 reaches the end of the swing angle θ, it has reached the right end position as shown in FIG. Valve 78 in the middle
When the O-ring 82 attached to the air port 84 passes the left end of the air port 84, the O-ring 81 passes the left end of the air port 83. Also, since the air port 85 is always between the O-rings 81 and 82,
For a short time when the O-rings 81 and 82 pass over the air ports 83 and 84, the air coming from the air pipe 85' is connected to the air pipes 83' and 84', but in the next stage, air is supplied to the air pipe 84'. is cut off, air pipe 8
Air is supplied only to 3'.

On the other hand, air supplied from the air pipe 83' is supplied to the arm 72,
Rotating cylinder 17 so that 73 rotates clockwise.
(not shown), and the air inside the rotating cylinder 17, which has rotated the arms 72 and 73 counterclockwise until now, will move to the left end stop 7 if the operating rod 75 moves even slightly to the left.
6 and the cover 86 of the switching valve 74 from the air pipe 8
4', air port 84, hole 86a and compression spring 80
It is exhausted through the space between the The rotating cylinder 17 then rotates in the opposite direction, that is, clockwise. Since the operating rod 75 is loosely engaged with the center hole of the valve 78, the arm 7
When the left end and right end stops 76 and 77 are not pressed by 2 and 73, they stand still at a position where the repulsive forces of the springs 79 and 80 are balanced, and the valve 78 is also pressed by the O ring 8.
Due to the frictional force of the contact parts 1 and 82, the compression spring 7
The arms 72 and 73 remain stationary at either end of the switching valve 74 unless pushed with a force that overcomes the frictional force via the arms 9 and 80.

As explained above, while supplying pressurized air from the air pipe 85' to the combination of the rotary cylinder 17 and the switching valve 74, the rotation is performed clockwise within the range of the swing angle θ.
Repeat counterclockwise rocking.

Next, in FIG. 1, when the rotary cylinder 17 is energized, the output shaft 18 swings, the gear 19 transmits the swing rotation to the gear 43, and the main shaft 29 is supported by the bearing 21 and swings. Therefore, the disk 32 and the air pipe 33 fixed thereto swing, and the pipe joint 39 fixed to the air pipe 33, the pipe joint 40 fixed to the pipe joint 39,
The nozzles 41 and 42 fixed to the pipe joint 40 swing by an angle obtained by multiplying the swing angle θ by the gear ratio of the gears 19 and 43.

On the other hand, if air is supplied from an external air source to the air inlet 88 fixed to the bearing 21, the air will flow through the circumferential groove 24, hole 38, hole 37, hole 36, hole 34, air pipe 35, tube seat 30, Air pipe 33, pipe joints 39, 4
0, air is ejected from the air blowing nozzle 41 and the air/water blowing nozzle 42.

Also, water flows from the water reservoir 47 to the water pipe 46 and the rotary joint 4.
4. Through the water hole 48, the water pipe 49, the through hole of the main shaft 29 (not shown), and the water pipe 51, the air/water blowing nozzle 42
When air is being blown out from the nozzle 42, it is attracted by the blown air and a mixture of air and water is ejected from the air/water blowing nozzle 42.

First, open the lid 64 of FIG. 2 and place the ashtray with the cigarette butt and ashes inside, and place it on the ashtray holder 58.
When the air stop valve 67 is closed, air is passed from an external air source to the air stop valve 67. When the dog 66 fixed to the lid 64 pushes the spool 68, the air stop valve is opened and air is supplied to the air cylinder 63 from the air source 89 through the air control unit 90. A lever 59 pivotally attached to the piston shaft 63a is biased counterclockwise in FIG. 2, and the ashtray holder 61 fixes the ashtray.

Now that each individual operation has been explained, the overall operation will be explained with reference to FIG. 9. The air supplied from the air source 89 is dehumidified by the air control unit, maintained at a constant pressure, and then refueled to reach the air stop valve 67. When the lid 64 shown in FIG. 2 is closed, the air stop valve 67 opens and the piston rod 63a of the air cylinder 63 protrudes. , As explained above, the ashtray holder 61
is pressed toward the ashtray holder 58 regardless of the presence or absence of an ashtray. When the lid 64 is opened, the piston rod 63
a moves backward, and the ashtray holder 61 moves away from the ashtray holder 58.

Even if there is water in the water reservoir 47, the water in the water reservoir 47 will not move unless air is blown out from the air/water blowing nozzle 42.

Water select valve, Air select valve 10, 11
When the operator sets it in the direction of the arrow a in FIG. 1, it opens, and when the operator sets it in the opposite direction to the arrow a, it closes.

When the air select valve 10 is opened, the rotary cylinder 17 cooperates with the switching valve 74 to rotate the nozzles 41 and 42 as described above and blow out the air. When the water select valve 11 is opened, the air/water blowing nozzle 42 blows out a spray. The nozzles 41 and 42 rotate around the ashtray by an angle obtained by multiplying the swing angle θ by the gear ratio of the gears 19 and 43 to clean the ashtray from each direction.

Therefore, the operator performs the following operations: connect the air source 89, fill the water reservoir 47 with water, open the lid 64 to discard the contents, place the dirty ashtray in the ashtray receiver 58, and close the lid. When the worker closes the water select valve 9 and the air select valves 9 and 10, the swinging nozzles 41 and 42 clean the ashtray, and after that, the operator closes the water select valve 9 and cleans the ashtray. When the ashtray is dried, the lid 64 is opened, and the ashtray is taken out, one work is completed. The above valves 9 and 10 are automatically controlled by the lid 64.
It is preferable that when the ashtray is closed, water and air are automatically blown out, then only air is blown out, and a timer is set to stop the ashtray when it is dry.

The water in the water reservoir 47 is replenished approximately every 50 to 60 operations, and the drain hole 70 and the drain port 6 are used for cleaning drainage and air.
Emit more.

Case 1 has dirty water and air as well as case 6.
It is blocked by the bearing 21 and does not enter. The air source 89 may be left connected even when no work is being done.

The gear portion may be enclosed in a small case, the rotating cylinder may be placed outside the case, and a water reservoir may be provided separately to facilitate maintenance and inspection.

Alternatively, the nozzle may be fixed and the ashtray may be rotated.

As explained above, this invention supports a main shaft by a bearing provided at one end of a closed container, and inside the closed container there is a rotating pipe equipped with a nozzle whose blowing direction can be adjusted toward the center at one end of the main shaft. One end of the body is fixed, and the other end of the main shaft is equipped with a drive device for rotating the main shaft, and a pipe line is provided to send air and water from an air source and a water reservoir to the nozzle via the main shaft, and a plurality of A water pipe for supplying water is arranged in a part of the nozzle, and the other end of the rotating body in the axial direction is opened, and the other end of the closed container is placed at a position where the air and spray blown from the nozzle come into contact through the opening. Since the ashtray washing device is provided with an ashtray holder for fixing the supported ashtray and a lid for taking the ashtray in and out of the closed container, the ashtray is thoroughly washed with water from around the ashtray, and no cleaning residue is left behind. In addition, in the drying process, air is similarly blown onto the ashtray from all around the ashtray, so there is no remaining water droplets or dry residue caused by the formation of areas that are not hit by the air. That is, complete cleaning and complete drying are achieved. Although the embodiment uses a rotating cylinder, a rotary drive device that rotates 360 degrees may also be used.
