Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mahjong tile cleaning device for cleaning mahjong tiles that have become soiled through use.

Prior Art and its Problems As mahjong tiles are repeatedly used, dirt accumulates on their surfaces, so it is desirable to remove this dirt and clean them. For this purpose, the mahjong tiles can be wiped one by one with a piece of cloth, but since mahjong parlors and the like handle many sets of tiles, such cleaning work is extremely troublesome. Therefore, a mahjong tile cleaning device has conventionally been used in which a set of tiles is put into a drum whose inner surface is also lined with cloth or sponge, and if necessary, a piece of cloth soaked in water is added and the drum is rotated. There is.

However, since this type of mahjong tile cleaning device simply uses the movement of tiles by rotating a drum, it takes a relatively long time to completely clean all the tiles. There is also a mahjong tile cleaning device described in Japanese Utility Model Application Publication No. 53-38469.

In the mahjong tile cleaning device described in the aforementioned Utility Model Application Publication No. 53-38469, the mahjong tiles are cleaned by rotating a plurality of cylindrical brush bodies in the same direction all at once via a gear mechanism. However, the cylindrical brush body is oriented vertically, and the tiles that enter the chute mechanism from the input port provided on the bottom plate of the hopper mechanism above the cylindrical brush body pass between the cylindrical brush bodies. While falling, the tiles are rubbed by a rotating cylindrical brush body containing a cleaning agent, so the conditions in which the tiles are wiped away as they pass between the cylindrical brush bodies are different. It is difficult to clean the tiles uniformly, and if a large number of tiles enter the chute mechanism from the input port at once, the tiles will be ejected without being sufficiently rubbed by the cylindrical brush body, and the brush of this cylindrical brush body will When the cylindrical brush body becomes worn out, the distance between the tips of the brushes of the cylindrical brush body increases, and the falling speed of the tiles increases, resulting in the tiles being ejected without being sufficiently rubbed, resulting in the disadvantage that the tiles are not sufficiently cleaned. be.

Means and Effects for Solving the Problems The present invention relates to an improvement of a mahjong tile cleaning device that eliminates the above-mentioned drawbacks. A rotating frame formed by integrally connecting each rotating plate to each other via a connecting member, and a rotating frame having a cylindrical shape and arranged along the circumferential part of the rotating frame so as to cover at least a large part of the circumferential part. a plurality of rotary wiping tools, each of which has both ends rotatably supported by each of the rotary plates; a rotation drive mechanism that rotates the rotary frame; The machine includes an interlocking drive mechanism that rotates each of them on its own axis, and a lid that can freely open and close an opening through which mahjong tiles can be taken in and taken out in a drum-shaped space surrounded by the left and right rotating plates and a plurality of rotating wipers. It is characterized by:

Since the present invention is configured as described above,
When the lid is opened, dirty mahjong tiles are put into the drum-shaped space, the lid is closed, and the rotation drive mechanism is operated, the rotation frame is rotated about the horizontal axis, and the rotation frame is rotated about the horizontal axis. The rotary wiping tool revolves in accordance with the rotation of the rotary frame and also rotates on its own axis by the interlocking drive mechanism, and the mahjong tiles housed in the drum-shaped space are lifted upward by the rotation of the rotary frame and then released by gravity. The mahjong tiles roll downward and turn around in all directions while being rubbed at a relatively high speed by the rotating wiping tool, thereby wiping away dirt on the surface of the mahjong tiles.

In this way, in the present invention, the mahjong tiles housed in the drum-shaped space are lifted upward by the rotating wiper that revolves in accordance with the rotation of the rotating frame, and then fall downward due to gravity. Because the rotation of the rotating wiping tool causes friction at high speed,
The dirt adhering to the surface of the mahjong tiles is wiped away evenly and evenly from any surface of the substantially rectangular mahjong tile surface and from any mahjong tile, and the time required for cleaning the tiles is reduced. Shorten.

Further, in the present invention, since the tile cleaning work time can be adjusted depending on the degree of dirt on the mahjong tiles, even heavily soiled mahjong tiles can be sufficiently cleaned.

Embodiment Hereinafter, the present invention will be described with reference to an illustrated embodiment. As shown in FIGS. 1 to 3, this mahjong tile cleaning device is equipped with a support frame 3 consisting of support plates 2a and 2b protruding from both left and right sides of a base 1, and each support frame 2a, 2b Disk-shaped rotary plates 4a and 4b are rotatably supported on the respective sides. The rotary plates 4a and 4b are connected to each other via a column-shaped connecting member 5, and the rotating plates 4 and the connecting member 5 constitute a drum-shaped rotating frame 6 with an open peripheral portion. The open peripheral portion of the rotating frame 6 rotatably supports a large number of rotating wiping tools 7 at both ends thereof on each of the rotating plates 4a and 4b, and their axes are parallel to the rotational axis of the rotating frame 6. and are substantially shielded by arranging them along the circumference of the rotary plates 4a, 4b (see FIG. 5, in which the last two rotary wipes have not yet been installed).

As shown in FIG. 4, the rotary wiping tool 7 is constructed by wrapping a wiping piece 9 made of thick cloth or sponge material around the circumferential surface of a cylindrical core material 8. A diametrical locking groove 11 (see FIG. 3) is provided at one end of the hole 10.
Rotary shafts 12 are rotatably supported on the right rotary plate 4b at the mounting positions of the rotary wiping tools 7, respectively, and the ends of the rotary shafts 12 protruding into the rotary frame 6 are diametrically mounted. A locking pin 13 is provided in a protruding manner. A sprocket 14 is fixed to the end of the rotating shaft 12 that projects outside the rotating frame 6, and the rotating shaft 12 is driven and rotated by a chain meshing with the sprocket 14, as will be described later. Left rotating plate 4a
, a spindle 1 is installed at the mounting position of each rotary wiping tool 7.
5 is provided. The support shaft 15 is slidably supported by a support tube 16 fixed to the rotary plate 4a, and protrudes into the rotary frame 6 by a compression spring 17 inserted between the support tube 16 and the support tube 16. The knob 18 at the end engages with the outer end surface of the support cylinder 16, thereby holding it in a predetermined protruding position. The rotary wiping tool 7 is operated by pulling the knob 18 by hand to connect the spindle 15 to the spring 17.
While pulling out the rotating frame 6 against the
Then, the shaft hole 10 and the support shaft 15 are aligned, the knob 18 is released, and the support shaft 15 is fitted.
By fitting the rotary plate into the shaft hole 10, it can be extremely easily installed between the rotary plates 4a and 4b. Also, by reversing the steps above, you can easily use 4a and 4.
It can be removed from b.

In this way, the rotating wiping tools 7 arranged in a row along the periphery of the rotating frame 6 are arranged such that adjacent rotating wiping tools 7 do not have their peripheral surfaces in contact with each other, and a slight gap is formed between them. There is. However, since the mahjong tiles stored inside the connecting member 5 cannot pass through this gap, the rotating frame 6 is
A substantial drum body is formed that defines the inside and outside of the drum. In this embodiment, the rotating wiping tool 7 is not provided all around the rotating frame 6, but an opening 19 where the rotating wiping tool 7 does not exist is formed in a part of the rotating frame 6. It is now possible to insert mahjong tiles inside. The opening 19 can be covered by a lid 20.

The left and right rotary plates 4a and 4b constituting the rotary frame 6 are rotatably supported by the left and right support plates 2a and 2b, respectively, as described above. Rotationally driven by a mechanism. That is, as shown in FIGS. 1, 6, and 7, the support plate 2b is fixed to the rotating plate 4b.
A sprocket 2 is attached to the end of the drive shaft 21, which is pivotally supported by the sprocket 2.
A drive chain 25 is spanned between this sprocket 22 and a sprocket 24 provided on an output shaft 23 of an electric motor (not shown), and the rotating frame 6 connects drive mechanisms 22, 25, 24. It is driven by the electric motor via the motor. The rotary plate 4b is also provided with an interlocking drive mechanism that rotates each of the rotary wiping tools 7 about an axis connecting the rotary shaft 12 and the support shaft 15 in conjunction with the rotation of the rotary frame 6. This interlocking drive mechanism includes an interlocking sprocket device 26, which is composed of a shaft 27 pivotally supported on the rotating plate 4b, and a large sprocket 28 and a small sprocket 29 fixed to the shaft 27. The small sprocket 29 is connected via a connecting chain 30 to a fixed sprocket 31 fixed to the support plate 2b. The large sprocket 28 is connected to the rotating shaft 12 that supports the rotating wiping tool 7.
It meshes with the interlocking chain 32 that goes around the rotating plate 4b while sequentially meshing with each sprocket 14 provided on the rotary plate 4b.

When the rotating frame 6 rotates clockwise by the interlocking mechanisms 24, 25, 22, for example as shown by arrow a in FIG.
The small sprocket 29 connected via
It rotates counterclockwise together with the large sprocket 28 as shown by arrow b. The interlocking chain 32 meshes with the inner portion of the large sprocket 28 as shown, and on the other hand, meshes with each sprocket 14 at its outer portion, so that when the large sprocket 28 rotates counterclockwise as described above, each The rotating wiping tools 7 each rotate clockwise as shown by arrow c. That is, the rotary wiping tool 7 revolves as indicated by arrow a and also rotates as indicated by arrow c.

To clean mahjong tiles using the mahjong tile cleaning device described above, as shown in FIG.
3 into the rotating frame 6 through the opening 19, and after covering the opening 19 with the lid 20, the rotating frame 6 is rotated. Due to the rotation of the rotating frame 6, the rotating wiper 7 revolves in the direction of the arrow a as described above, whereby the mahjong tiles 33 are agitated and come into contact with the surface of the rotating wiper 7 one after another, causing the cleaning wipes stretched on the surface to be agitated. The surface of the mahjong tiles 33 is rubbed by the piece 9 (FIG. 4) to wipe away dirt. At this time, the rotating wiping tool 7 rotates in the direction of the arrow c along with the revolution, and the surface of the rotating wiping tool 7 is opposite to the revolution direction on the inside of the rotating frame 6, that is, on the side that contacts the mahjong tiles 33. Since the mahjong tiles 33 are moved in the direction, the stirring of the mahjong tiles 33 is further promoted, and the relative speed between the surface of the mahjong tiles 33 and the surface of the rotary wiping tool 7 is increased, so that the mahjong tiles 33
The dirt adhering to the surface of the wiping member 9 can be more effectively wiped away by the wiping piece 9. As described above, the gap 34 is formed between adjacent rotary wiping tools 7, so that the dirt that has been wiped and adhered to the rotary wiping tool 7 side is transferred to the rotary frame again by the adjacent rotary wiping tool 7. Relatively large dust and the like that are not carried into the interior of the rotary wiping tool 6 and are difficult to adhere to the surface of the rotary wiping tool 7 are discharged to the outside of the rotary frame 6 by centrifugal force after passing through the gap 34. In this way, the mahjong tiles 33 in the rotary frame 6 are quickly cleaned by the sufficient stirring motion and good wiping action of the rotary wiping tool 7, which rotates on its axis as well as revolves. If necessary, the entire rotating frame 6 may be covered with a dustproof cover to prevent dust discharged from the rotating frame 6 from dispersing into the room.
