Description

  The present invention relates to an automatic mahjong tile cleaning device that cleans a dirty mahjong tile used in a game after the game.

  When a mahjong game is played, the mahjong tile is soiled by dirt, dust, etc., and the mahjong tile is washed and cleaned after the game is over. As such a cleaning and cleaning method, it is generally carried out by wiping with a cloth manually. However, since a great deal of labor and time is required, for example, as described in Patent Document 1, a sponge is used. A spherical cleaning body wrapped with a cleaning material such as a cloth is put on a turntable in a fully automatic mahjong table and stirred together with the mahjong tile on the turntable by rotating the turntable. A cleaning method has been developed.

  In addition to the cleaning method using the turntable of the fully automatic mahjong table, as described in Patent Document 2, the mahjong tile automatic washing machine used in the game is dropped while standing. A hopper with an introduction pipe, an intermittent rotary table provided with through holes in the outer peripheral part that can be accommodated and held one by one with the upper and lower ends exposed to the outside, and a hopper falling from the introduction pipe, A pair of upper and lower first rotating brushes for cleaning the upper and lower end surfaces of the ridges that are arranged in the course of movement of the through holes of the intermittent rotation table and project from the through holes, and the ridges for which the upper and lower end surfaces have been cleaned A supply passage that is supplied to the guide passage that is separated and extends horizontally, a transfer rod that pushes the rod supplied in the guide passage and passes through the guide passage, and an unwashed bag disposed in the middle of the guide passage. Washing machines are known to consist of a pair of upper and lower second rotary brush for cleaning the other tetrahedron.

  However, according to the former mahjong tile cleaning and cleaning method, when the mahjong tile and the spherical cleaning body are agitated by the rotation of the turntable, the spherical cleaning body is lighter than the mahjong tile. Not only does the cleaning efficiency drop significantly when riding on the mahjong tile, but there is also a risk that mahjong tiles that do not come into contact with the spherical cleaning body may cause uneven cleaning, and in addition, contact with the spherical cleaning body. Since the cleaning time is extremely short, there is a problem that a sufficient cleaning effect cannot be expected.

  On the other hand, according to the latter mahjong tile, the used mahjong tile can be taken out of the automatic mahjong tile table and washed by this washing machine after the mahjong game is over. Since the mahjong tile must be accommodated in the through-hole provided in the outer peripheral portion, the intermittent rotary table must be temporarily stopped and wait for the mahjong tile to be accommodated in the through-hole, Therefore, not only does it take a long time to clean all mahjong tiles due to a decrease in cleaning efficiency, but also after the mahjong tiles are housed in the through holes of the intermittent rotating table, the intermittent rotating table is rotated. In addition, a sensor that detects that mahjong tiles are housed in the cum-through hole is required, and there is a possibility that the structure becomes complicated and a failure is likely to occur.

  Further, the upper and lower end surfaces of the ridge protruding from the through hole are cleaned by a pair of upper and lower first rotating brushes arranged on the way of movement of the through hole of the intermittent rotation table. Since the time for passing through the brush is short, sufficient cleaning is not performed, and in order to improve the cleaning effect, the intermittent rotary table may be stopped when the through hole reaches the position of the first rotary brush. Then, there is a problem that it takes a long time to clean all mahjong tiles as well as a new sensor for performing the operation.

  Furthermore, in order to clean the other four sides of the mahjong tile that has been cleaned on the two sides by the first rotating brush, the mahjong tile is removed from the intermittent rotating table and supplied into a horizontally extending guide passage to move the mahjong tile. Since it is configured to be pushed by the scissors and cleaned by the pair of upper and lower second rotating brushes disposed in the middle of the guide passage, the structure of the entire cleaning machine becomes complicated and expensive, and the second There is a problem that the cleaning time with the rotating brush is extremely short and effective cleaning cannot be performed.

  The present invention has been made in view of such problems.

The mahjong tile A is sequentially adsorbed and conveyed to the first conveying rotating disk 4 side by the rotation of the rotating disk 3.

  A stopper 12 is disposed above the outer periphery of the first transport rotary disk 4 in the course of rotation of the mahjong tile supply rotating disk 3 so as to face the mahjong tile A conveyed by the mahjong tile supply rotation disk 3. Accordingly, the front end face of the mahjong tile A, which is attracted to the magnet 11 in accordance with the rotation of the rotating disk 3 and faces the rotating direction of the rotating disk 3, is shown in FIGS. In this manner, the stopper 12 abuts against the vertical plate surface 12a.

  When the mahjong tile A hits the stopper 12 and is received in this way, it can no longer move in the rotating direction of the rotating disk 3, and the rotating circle is peeled off from the magnet 11 as the rotating disk 3 rotates. It moves relative to the outer peripheral surface side of the plate 3 where the magnet 11 is not provided, and travels along the vertical plate surface 12a of the stopper 12 while maintaining the posture when the attracting force by the magnet 11 is released and attracted to the magnet 11. It is dropped and received on the conveyance start end portion of the first fixed horizontal guide plate 13 disposed along the outer peripheral portion of the lower surface of the first conveyance rotation disk 4 immediately below the lever 12.

  On the first fixed horizontal guide plate 13, several (four in the figure) receiving protrusions 14 projecting from the outer peripheral surface of the first transport rotating disk 4 are formed on the first transport rotating disk 4. The mahjong tile A that has been circulated and moved as a result of rotation and dropped and received on the conveyance start end of the first fixed horizontal guide plate 13 is sequentially received by the receiving protrusions 14 that have circulated to this position. The first fixed horizontal guide plate 13 is conveyed toward the inlet side of the first fixed cleaning tool 6 according to the rotation of the first conveying rotary disk 4 while the end face is pushed.

  A first fixed cleaning tool 21 is disposed in front of the first fixed cleaning tool 6, and the mahjong tile A transported by the rotation of the first transport rotating disk 4 is passing through the first fixed cleaning tool 21. Further, the lining cleaning member 23 having a U-shaped cross section of the first fixed cleaning 21 is rubbed with the three surfaces of the back surface and both side surfaces directed in the vertical direction by the cleaning liquid impregnated in the lining cleaning member 23. As shown in FIG. 8 and FIG. 9, the three surfaces of the lining cleaning member 8 having a U-shaped cross-section are transferred to the first fixed cleaning tool 6 and then passed through the first fixed cleaning tool 6. It is cleaned while rubbing.

  Thus, the mahjong tile A that has passed through the first fixed cleaning tool 21 and the first fixed cleaning tool 6 while being pushed forward by the respective receiving protrusions 14 of the first transport rotary disk 4 is the outlet of the first fixed cleaning tool 6. It falls on the inclined chute 16 facing its upper end, and its front end surface changes its direction downward while standing and is placed along the outer peripheral portion of the lower surface of the second transport rotary disk 5. The second fixed horizontal guide plate 15 is dropped and received on the conveyance start end portion.

  On the second fixed horizontal guide plate 15, several pieces (four pieces in the figure) of receiving protrusions 17 projecting from the outer peripheral surface of the second transport rotary disk 5 are formed on the second transport rotary disk 5. As shown in FIGS. 10 and 11, the mahjong tile A, which has been circulated and moved as a result of rotation, has fallen and received on the conveyance start end of the second fixed horizontal guide plate 15 in an upright state, as shown in FIGS. Are sequentially conveyed by the receiving protrusion 17 that has been circulated to the inlet side of the second fixed cleaning tool 7 on the second fixed horizontal guide plate 15 in accordance with the rotation of the second transfer rotary disk 5 while the rear end face is being pushed. The

  At this time, when the mahjong tile A is fed from the inclined chute 16 onto the second fixed horizontal guide plate 15 and rises on the second fixed horizontal guide plate 15, the mahjong tile A faces outward on the first transport rotary disk 4 side. The back surface directed toward the surface is directed inward and is directed in the circumferential direction of the second transport rotating disk 5 directed in the vertical direction, and the front and rear end surfaces are directed in the vertical direction. That is, the other three surfaces cleaned by the lining cleaning member 8 of the first fixed cleaning tool 6 can rub against the lining cleaning member 24 of the second fixed cleaning tool 22 and the lining cleaning member 9 of the second fixed cleaning tool 7. Become posture.

  In this state, the mahjong tile A is pushed on the second fixed horizontal guide plate 15 on the second fixed horizontal guide plate 15 in accordance with the rotation of the second transport rotary disk 5 while the rear end surface of the mahjong tile A is pushed by the receiving protrusion 17 as described above. Although the second fixed cleaning tool 22 is disposed in front of the second fixed cleaning tool 7, the mahjong tile A is first fed into the second fixed cleaning tool 22. During the passage, the remaining three surfaces that have not been cleaned and cleaned by the first fixed cleaning tool 6 or the first fixed cleaning tool 21 are rubbed against the lining cleaning member 24 having a U-shaped cross section of the second fixed cleaning 22. As shown in FIG. 13 and FIG. 14, it is cleaned with the cleaning liquid impregnated in the lining cleaning member 24 while being transferred to the second fixed cleaning tool 7 and passes through the second fixed cleaning tool 7. Next, clean the lining cleaning member 9 with a U-shaped cross section while rubbing the remaining three surfaces. It is.

  The first and second fixed cleaning tools 6 and 7 have the arc lengths of the lining cleaning members 8 and 9 for rubbing the mahjong tile A so as to be about 5 to 10 times the length of the mahjong tile A. Accordingly, the mahjong tile A is cleaned and cleaned cleanly and reliably while passing through these lining cleaning members 8 and 9.

  While the mahjong tile A is pushed forward by the receiving projection piece 17 as the second transport rotary disk 5 rotates, when it passes through the second fixed cleaning tool 7, it leaves the receiving projection piece 17 and exits from the second fixed cleaning tool 7. It falls on the discharge chute 18 disposed below, and is stored in an appropriate storage container or the like installed below the discharge chute 18. In addition, when the first and second fixed cleaning tools 7 and the first and second fixed cleaning tools 21 and 22 become dirty after long use, a new fixed cleaning tool and fixed cleaning tool having the same structure are used. It is configured to be replaced.

  Further, in the above embodiment, as the supply means for sending the mahjong tiles A one by one to the first transport rotating disk 4 at regular intervals, the rotary table 2 for receiving a large number of mahjong tiles A and the rotary table 2 on the outer peripheral surface.
