Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic mahjong table, and in particular to a tile guide for guiding tiles taken out from a tile stirring means by a tile takeout means to a two-tiered tile stacking means. It is about the means.

[Prior art and its problems] Conventionally, as a tile guide means for an automatic mahjong table, there is one disclosed in, for example, Japanese Patent Laid-Open No. 159775/1983.

The tiles are laid down on a turntable and stirred, then attracted by magnets arranged on a disc-shaped alignment control member, placed on a slope conveyor, and transferred to the tip of the slope conveyor. A horizontal conveyor fixed at fixed intervals moves, and the tiles placed on the tip of the slope conveyor are attracted by the magnets of the horizontal conveyor. It is intended to be transferred to

However, in the horizontal conveyor of the slope conveyor which is the tile guiding means described above, the distance for transporting the tiles is long, and it takes a long time to transport the tiles to the two-tiered tile stacking means. Furthermore, a power mechanism such as a motor is required to operate these conveyors.

Furthermore, since this horizontal conveyor rotates above the two-tiered tile stacking means with the tiles attracted to the magnets of the base, there is a risk that the tiles may fall from the horizontal conveyor due to vibrations. Furthermore, this horizontal conveyor must be provided above the two-tiered tile stacking means, which increases the vertical thickness of the automatic mahjong table.

Also, JP-A-58-221974 and JP-A-59-
No. 49789 proposes the following automatic mahjong table.

That is, as a tile guiding means in an automatic mahjong table, an inflow guide is provided that protrudes from the outside of the inlet of the frame, which is a part of the tile stacking means, and this inflow guide is magnetized by the magnetic material of the takeout board. It merely has the effect of arranging the tiles in a certain direction when the tiles that have been placed and taken out are fed into the inlet of the frame that is part of the two-tiered tile stacking means. Furthermore, when the number of tiles in the frame reaches a predetermined number, the pushing rod that pushes out the tiles in the frame is pushed up by the action of the detector and the solenoid activated by it, and the pushing out of the tiles in the frame stops. The inflow port is configured to be closed by the last tile sent in, thereby preventing subsequent tiles from entering. If such a configuration prevents the subsequent tiles from entering, the subsequent tiles will repeatedly collide with the tiles stacked in two levels, giving a shock to the entire tiles stacked in two levels within the frame. Therefore, there is a risk that the tiles stacked in two tiers within the frame may collapse, resulting in a hindrance to the series of operations at the automatic mahjong table.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the automatic mahjong table according to the present invention has tiles with a magnetic material embedded therein, and a tile stirring means disposed below the top plate. a tile take-out means comprising a rotating member with magnets arranged at required locations for taking in the tiles from the tile stirring means; a tile guide means for guiding the tiles transferred by the tile take-out means;
The tile guiding means includes a two-tiered tile stacking means for stacking the tiles guided from the tile guiding means in two tiers and arranging them on the top plate, and the tile guiding means follows the locus of the tiles attracted by the rotating member. A guideway is formed along the guideway, and after arranging a predetermined number of tiles in the first tier in the two-tiered tile stacking means, a guideway is formed along the guideway in order to arrange the tiles in the second tier on top of the tiles in the first tier. A partition piece for opening and closing the entrance is provided on the entrance side, and counting sensing means for controlling the blocking of the entrance by the partition piece is arranged at an appropriate position on the guideway. A sensing device is arranged to control the opening of the entrance by the partition piece, and on the opposite side of the entrance side of the guideway, a mounting part formed to protrude outward from the rotating member serves as an insertion opening of the two-tiered tile stacking means. They are connected to each other, and further include a pushing means for sequentially pushing the tiles on the placing portion into the insertion opening in response to the ejecting action of the rotating member.

[Function] The present invention allows the tile guiding means to move the tile taken out from the tile stirring means by adsorption by the rotating member of the tile taking out means along the trajectory of the tile without deviating from this trajectory. The inside of the container can be transferred and fed onto the placing section connected to the insertion opening of the two-tiered tile stacking means, and the tiles on the placing section can be sequentially fed into the insertion opening of the two-tiered tile stacking means by this pushing means. can.

In addition, when a predetermined number of tiles (usually 17) pass through the taxiway, a partition piece installed at the entrance of the taxiway is activated under the control of a counting sensing device installed on the taxiway, and the entrance of the taxiway is closed. During the blockage, no tiles enter the guideway, so after arranging a predetermined number of tiles in the first tier in the two-tiered tile stacking means, a second tier is placed on top of the tiles in the first tier. When the preparation time for arranging the tiles of the target is obtained, and the second stage of tiles is ready to be placed, the partition piece is activated by the sensing device that controls the opening of the entrance, and the entrance of the taxiway is opened and the second row of tiles is ready. It becomes possible for tiles to be arranged as tiles in a row to enter. When a predetermined number of tiles placed on the second stage pass through the taxiway, a partition piece installed at the entrance of the taxiway is activated under the control of a counting sensing device installed on the taxiway. is blocked,
After that, no tiles can be entered.

[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. As shown in FIG. A mouth part 16 is provided, and this mouth part 16 is
Usually, it is closed by a lid plate 18 that moves up and down, and the tiles 14 are dropped into the lid plate 18 by raising the lid plate 18. 20 is each switch for operating the automatic mahjong table 10 provided on the cover plate 18, and 22 is a support leg.

As shown in FIG. 2, the tiles 14 have a magnetic material embedded inside. In this embodiment, a magnet 24 is used as the magnetic material, and is embedded in the center of the front and back surfaces of the tiles 14 on which characters and figures are displayed. Two sets are used, one of which is played, and the other tiles 14 are stirred within the automatic mahjong table 10, stacked in two tiers, and kept in line. In this case, the magnet 24 used is one that does not attract the tiles 14 to each other. Further, the magnetic material is not limited to the magnet 24, but other magnetic metal pieces such as pieces of iron may be buried, and in this case, the magnetic metal pieces are buried offset to the back side of the tiles 14.

A tile stirring means 26 is provided below the top plate 12, and a circular umbrella-shaped rotating body 28 that is slightly lowered outward from the center is rotated through a gear 30 attached to the lower surface side of the rotating body 28. It is rotated by a motor 32 (see FIG. 5). As a result, the tiles 14 dropped from the opening 16 of the top plate 12 after the competition are rolled and stirred by the rotation of the rotating body 28, and the tiles 14 are moved outward on the rotating body 28 by centrifugal force. It's starting to move. Note that the rotating body 28 may be a horizontal disc-shaped body as long as a rotational centrifugal force is sufficiently applied.

Reference numeral 34 denotes tile take-out means for sorting and taking in the front and back sides of the tiles 14 from the tile stirring means 26, and these are provided at four equally spaced locations on the outside of the rotating body 28 (see FIG. 3). This tile extraction means 34
As shown in FIG. 4, this is a rotating member 36 in the shape of a disc with both sides cut out, and magnets 38, 38 are disposed at two opposing locations, and the periphery of this rotating member 36 is It is provided above the periphery of the rotating body 28 at an interval that allows the tiles 14 to pass through. Further, behind the magnets 38, 38,
Flexible protrusions 40, 40 are provided that protrude below the rotating member 36.

As shown in FIG. 5, this rotating member 36 is rotatably supported by a shaft 44 having a gear 42 below, and the magnet 38 of the rotating member 36 and the periphery of the rotating body 28 of the tile stirring means 26 are connected to each other. The gear 30 of the rotating body 28 and the gear 42 of the rotating member 36 are meshed with each other so that they rotate in the same direction and at substantially the same speed, and are rotated in conjunction with each other by the motor 32.

Furthermore, below the periphery of the rotating body 28, magnets 48 are placed at two opposite locations similar to the rotating member 36.
A plate 46 having a diameter of 48 is supported by the shaft 44 and configured to rotate together with the rotating member 36, and the plate 46 is arranged parallel to the rotating member 36,
The line connecting the two magnets 38, 38 of the rotating member 36 and the line connecting the two magnets 48, 48 of the plate 46 are arranged so as to be perpendicular to each other.

The magnet 38 of the rotating member 36 is arranged so that the back side of the tile 14 is attracted to the lower surface of the magnet 38 of the rotating member 36.
The polarity of each magnet 38, 24 of the plate 46 is determined, and the magnet 48 of the plate 46 is connected to the upper surface of the plate 14.
The polarities of the magnets 48 and 24 on this plate 46 and the tiles 14 are determined so that the back sides of the tiles 4 and 4 repel each other. For example, if the front side of the magnet 24 of the tile 14 is the north pole and the back side is the south pole, the bottom side of the magnet 38 of the rotating member 36 is the north pole, and the magnet 4 of the plate 46 is the north pole.
The upper surface side at 8 is the S pole. Also, the above N
It is also possible to reverse the polarity and the south polarity.

Therefore, as shown in FIG. 4, among the tiles 14 in various states being rotated around the periphery of the rotating body 28 of the tile stirring means 26, if the back side of the tile 14 is facing upward, the rotating member 36 The tiles 14 are attracted by the magnets 38 and transferred to the two-level stacking means 52 via the tile guiding means 50, which will be described later.On the other hand, if the back side of the tiles 14 is facing downward, the magnets 24 embedded in the tiles 14
and the magnet 38 of the rotating member 36, the rotating member 3
6, a force acts to repel the front side of the tile 14, and a force to attract the back side acts, and the tile 14 turns itself around and is attracted to the magnet 38 of the rotating member 36, or
Alternatively, the back side of the tile 14 is turned upward by the magnet 48 of the plate 46, and the tile 14 is transferred to the two-tiered tile stacking means 52 by the other tile take-out means 34 in the same manner as described above.

In this manner, the front and back sides of the tiles 14 can be sorted and taken in from the tile stirring means 26 by the tile take-out means 34. Note that if the back side of the tile 14 faces inward or outward from the rotating body 28, that is, the tile 14
Even when the tile 14 is in a horizontal position, the tile 14 rotates by itself so that the back side of the tile 14 faces upward as described above and is attracted to the rotating member 36, or is reversed by the plate 46.
The tiles are attracted to another tile takeout means 34 and transferred to the two-tiered tile stacking means 52.

At this time, the position where the circumferential edge of the rotating body 28 and the magnet 38 provided on the rotating member 36 face each other during rotation is the same position as the initial facing position on the circumferential edge of the rotating body 28 when the rotating member 36 rotates several times. Rather than rotating, the facing positions are sequentially shifted as the rotating body 28 and rotating member 36 rotate.

Note that if the magnetic material embedded in the tiles 14 is a piece of iron or the like, some kind of tile reversing means is provided in the tile stirring means 26 or the like.

The tiles 14 transferred by the tile takeout means 34 as described above are guided by the tile guide means 50 and transferred to the tile stacking means 52, as shown in FIGS. 3 and 7. . In this way, since the rotating members 36 are provided at four equally spaced locations on the rotating body 28, the tiles 14 can be taken out efficiently. Further, since the plate 46 inverts the tiles 14 so that the back side of the tiles 14 faces upward, the tiles 14 can be taken out more efficiently, which is effective.

In this embodiment, a plate 46 is provided to improve the efficiency of taking out the tiles 14, but it is not necessary to provide this plate 46, and the rotating member 3
6 is enough to take out the tile 14.

are stirred within the automatic mahjong table 10 and are waiting in a two-tiered state. When the competition on the top board 12 is finished, one tile 14 is dropped into the mouth 16, and when this is finished, the other tiles 14 waiting in the automatic mahjong table 10 are stacked in two layers on the top board 12. and placed in alignment.

[Effects of the Invention] As is clear from the above description, the present invention allows the tile guide means to guide the tile along the trajectory of the tile attracted to the rotating member of the tile take-out means. is short, and the transfer time is also short. Therefore, the tiles can be stacked in two tiers and aligned in a short time inside the automatic mahjong table.

In addition, since the tiles are attracted to the rotating member and transferred to the insertion opening of the two-tiered tile stacking means while being guided by the tile guide means, there is no need to provide any power mechanism to the tile guide means, and the mechanism is simple. It is lightweight and economical.

Furthermore, in this tile guide means, since the guide path covers the lower part of the tiles transferred by the tile takeout means, there is no risk of the tiles falling.
Furthermore, this tile guiding means is arranged at approximately the same height as the insertion opening of the tile stacking means, so that the thickness of the automatic mahjong table in the vertical direction is not increased.

Moreover, because a partition piece is provided on the entrance side of the taxiway, a counting sensing device is installed to control the blocking of this entrance, and a sensing device is installed to control the opening of this entrance, the predetermined number of tiles in the two-tiered stacking means is After arranging the first row of tiles, the second row of tiles can be arranged on top of the first row of tiles very smoothly.
