Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to an automatic mahjong table, and in particular to a device for stacking tiles taken out from a tile stirring means by a tile takeout means in two tiers and arranging them on a top plate. This invention relates to a means for stacking tiles in two stages.

[Prior art and its problems] Conventionally, as a means for stacking tiles in two stages in an automatic mahjong table, for example, Japanese Patent Application Laid-Open No. 58-159773 and Japanese Patent Application Laid-Open No. 58-1989
There is one shown in No. 159776.

These are a standby table with a sawtooth slope on the top, a pallet that can be moved up and down to align the tiles on the top plate, and a push plate for transferring the tiles on the standby table to a barre. The tiles that are being transported and suspended by the magnets of the conveyor installed above the waiting table are brought into contact with the stopper at the end of the waiting table or the tiles that have fallen on the waiting table, and the tiles are sequentially placed on the waiting table. The tiles are dropped and stacked in two tiers, the pallet is lowered to the standby position, the tiles on the standby stand are transferred to the pallet using a push plate, the pallet is raised and the tiles are arranged on the top plate. There is.

However, since the top surface of this standby table is formed into a sawtooth inclined surface, the tiles placed on it are tilted and easily fall apart, and when placing the tiles on the standby stand, Since the tiles hit the stopper or the tiles that have fallen onto the standby table and fall onto the standby table, the tiles tend to fall over.

Furthermore, since the push plate and the pallet are operated separately, there is a risk that the timing may be incorrect and the tiles stacked in two levels may be broken. Furthermore, power is required to operate each of them, the mechanism is complicated, the overall size of the automatic mahjong table becomes large, and it is not economical.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides tiles with a magnetic material embedded therein, a tile stirring means disposed below the top plate,
This automatic mahjong table is comprised of a tile take-out means that takes in and transfers tiles from the tile stirring means, and a tile two-tier stacking means that stacks the tiles transferred by the tile take-out means in two tiers and arranges them on the top plate. , the said two-level tile stacking means has a horizontal waiting table on which the tiles pushed in from the insertion opening are stacked and placed, and an arrangement having the same shape as the waiting table for transferring tiles from the waiting table and lifting them onto the top plate. It consists of a stand and a push-out mechanism for transferring the tiles placed on the standby stand to the alignment stand, and these stand-by stand, alignment stand, and push-out mechanism are connected to each cam provided on a single cam shaft. The camshaft is configured such that one rotation of the camshaft causes one stroke through an interlocking member.

[Function] By rotating the camshaft of the two-tiered tile stacking means once, the present invention allows the tiles that have been adsorbed by the tile removal means from the tile stirring means and sequentially fed into the insertion opening of the two-tiered tile stacking means to be removed. , the tiles are stacked in two tiers on the waiting table without falling over, and as the waiting table rises, the sorting table lowers so that they are almost flush with each other, and in this state, the pushing mechanism pushes out the tiles on the waiting table and onto the sorting table. The tiles can be smoothly replaced, the push-out mechanism moves 1 m, the waiting table lowers, and the alignment table rises to be flush with the top plate, allowing the tiles to be aligned on the top plate.

[Example] Next, an example of the present invention will be described based on the drawings.
As shown in FIG. 1, reference numeral 10 is an automatic mahjong table, and the top plate 12 is provided with a mouth 16 in the center thereof into which tiles 14 are dropped. Board 18
The cover plate 18 is raised and the tiles 14 are closed.
It is designed to be able to drop. Reference numeral 20 indicates respective switches for operating the automatic mahjong table 10 provided on the cover plate 18, and 22 indicates support legs.

As shown in FIG. 2, the tiles 14 have a magnetic material embedded inside. In this embodiment, a magnet 2 is used as the magnetic material.
This automatic mahjong table 10
In this game, two sets of tiles 14 are used to play one game, and the other tiles 14 are stirred within the automatic mahjong medium 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 agitating means 26 is provided below the top plate 12, which includes a circular umbrella-shaped rotating body 28 that is slightly lowered outward from the center and a gear 30 attached to one side thereof. It is rotated by a motor 32 through the
(See Figure 5). As a result, the tiles 14 dropped from the opening 16 of the top plate 12 after the competition are transferred 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 has become. 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). As shown in FIG. 4, this tile takeout means 34 is a rotary member 36 in the form of a circular plate with both sides cut out, and magnets 38 and 38 are disposed at two opposing positions of the rotary member 36. The periphery of the member 36 is located above the periphery of the rotating body 28 at a distance that allows the tiles 14 to pass through.

Also, behind the magnets 38, 38, this rotating member 3
A flexible protrusion 40.40 is provided that protrudes downwardly.

This rotating member 36 has a gear 4 disposed downwardly as shown in FIG.
is rotatably supported by @44 having 2;
The gear 30 of the rotary member 28 and the gear 42 of the rotary member 36 are meshed with each other so that the magnet 38 of the rotary member 36 and the periphery of the rotary member 28 of the tile stirring means 26 rotate in the same direction and at approximately the same speed. They are configured to rotate in conjunction with each other.

Further, below the periphery of the rotating body 28, the rotating member 36
A plate 46 having magnets 48 and 48 at two opposite locations similar to the above is supported by the shaft 44 and is configured to rotate at the same time as the rotating member 36.
6 and two magnets 38.3 of the rotating member 36.
8 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 has the tile 14 on its lower surface.
The polarity of each magnet 38, 24 of this rotating member 36 and the tile 14 is determined so that the back side of the plate 46 is attracted to the magnet 4 of the plate 46.
8, the polarity of each magnet 48, 24 of this plate 46 and the tile 14 is determined so that the upper surface thereof and the back side of the tile 14 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 3fJ is the north pole, and the top side of the magnet 48 of the plate 46 is the south pole. shall be. It is also possible to reverse the above N and S poles.

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 surface of the tile 14 is facing upward, the magnet of the rotating member 36 38 and transferred to the tile two-tier stacking means 52 via the tile guiding means 50, which will be described later.
4, the back side of which is facing downward, is connected to the rotating member 3 by the magnet 24 embedded in the tile 14 and the magnet 38 of the rotating member 36.
6, a force acts to repel the front side of the tile 14, and a force to attract the back side acts, so that the tile 14 turns itself around and is attracted to the magnet 38 of the rotating member 36, or the tile 14 is attracted to the magnet 38 of the rotating member 36, or 48 so that the back side of the tile 14 faces upward, and is transferred to the tile stacking means 52 by another tile takeout means 34 in the same manner as described above.

In this way, the tile stirring means 26 is controlled by the tile taking out means 34.
The front and back sides of the tiles 14 can be sorted out and captured. Note that even when the back side of the tile 14 faces inward or outward from the rotating body 28, that is, even when the tile 14 is oriented sideways, the tile 14 can be rotated by itself so that the back side of the tile 14 faces upward, as described above. It rotates and is attracted to the rotating member 36, or is reversed by the plate 46, and is 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 3G 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 and effectively.

In addition, in this embodiment, the board 46 is provided to hold the tiles 14.

This mode selection switch 142 is provided protrudingly at the height of the two-stage valve of the tile 14 and also functions as a stopper for the tile 14.
The one shown is for four people, but this position is the standby stand 8.
By returning it to the switch section 142' on the side of the insertion opening 64 of No. 2, it can be selectively used for three people.

Further, 144 and 144' are photosensors provided at the ends of the camshaft 88, and are used to control the rotation angle of the camshaft 88.

The process of arranging the tiles 14 after the competition path r in two stacks on the top plate 12 using the automatic mahjong table 10 described above will be explained.

When the mahjong competition ends, by operating switch 20,
The mouth part 16 of the middle part of the top plate 12 is opened, and the tiles 14 are dropped into the opened mouth part 16.

Further, the switch 20 is operated to close the mouth 16, and the motor 32 inside the automatic mahjong table 10 is operated to rotate the rotating body 28 of the tile stirring means 26 and the rotating member 36 of the tile taking out means 34. .

The tiles 14 dropped in this way are transferred to the tile stirring means 2.
The tiles 14 are stirred and moved on the periphery of the rotating body 28 by the centrifugal force caused by the rotation of the rotating body 28 and the inclination of the umbrella-shaped rotating body 28.

When the tile 14 rotating on the periphery of the rotating body 28 comes close to the lower side of the magnet 38 attached to the rotating member 36 of the tile takeout means 34 rotating above the tile 14, the tile 14 rotates.
Due to the action of the magnet 24 embedded in the tile 4 and the magnet 38 of the rotating member 36, the tile 14 is attracted to the magnet 38 of the rotating member 36 so that the back side of the tile 14 faces upward.

At this time, if the tiles 14 on the periphery of the rotating body 28 are rotating with their backs facing up, the tiles 14 are easily attracted to the magnets 38 of the rotating member 36 while remaining as they are;
When the back side of the tile 14 is facing downward, the magnets 24 and 38 repel each other by the magnet 24 embedded in the tile 14 and the magnet 38 of the rotating member 36, and the tile 14 turns itself around and moves toward the rotating member 36. is attracted to the magnet 38. In addition, the magnet 48 of the plate 46 located below the rotating body 28 repels and reverses the tiles 14 passing near the top of the plate 46, and the rotating body 28
The periphery of the tile 8 is rotated so that the back side of the tile 14 is facing up, and the tile 14 is attracted to the magnet 38 of the other rotating member 36.

Then, the tiles 14 are attracted to the magnets 38 of the rotating member 36 of the tile take-out means 34 and enter from the entrance 60 of the guide path 58 of the tile guide means 50, and the tiles 14 enter the placement section 62 of the tile guide means 50.
A little before coming to the top, that is, the curved part 61 of the taxiway 58
A cam 7 that rotates in the same manner as the rotating member 36 when positioned above.
4 pushes the horizontal bar 70, and the push-in piece 72 moves to the state shown by the solid line in FIG.

Further, the tiles 14 try to rotate while being attracted to the magnets 38 of the rotating member 36, but are blocked by the curved portion 61a on the base 56 side of the curved portion 61, and are detached from the magnets 38 of the rotating member 36, and then rotate behind the magnets 38. It is pushed by the protruding piece 4o and is attracted by the magnet 66 on the lower surface of the mounting section 62, moves along the curved portion 61, and is placed on the mounting section 62, and the cam 74 rotates together with the rotating member 36. The pushing piece 72 moves in the direction of the arrow in FIG. 7 via the horizontal bar 10 and the rollers 73, and pushes the tiles 14 on the placement section 62 into the insertion opening 64 of the two-tiered tile stacking means 52.

In this way, the tiles 1 on the rotating body 28 of the tile stirring means 26 are
4 are sequentially sent onto the standby table 82 of the two-tiered tile stacking means 52 by the tile takeout means 34 via the tile guiding means 50.

When the 17th tile 14 is fed into the standby table 82 of the tile stacking means 52, the photosensor 80 of the tile guide means 50 operates, and the partition piece 76 causes the tile guide means 50 to
The entrance 60 of the taxiway 58 is closed. Similarly, when the 17th tile 14 is fed into the adjacent tile stacking means 52, the entrance 60 of the guiding path 58 is closed by the partition piece 16.

In this way, when 17 tiles 14 are arranged on each standby table 82.82 of each two-tiered tile stacking means 52.52, the camshaft motor 98 is activated to rotate the camshaft 88 to The standby stand 82.82 is lowered by the height of the tile 14 in the lying state. At this time, the photo sensor 1 of the camshaft 88
44' works to stop the camshaft 88, bring the standby table 82 into the state shown by the one-dot chain line in FIG. 11, lower the partition piece 76, and open the entrance 60 of the guideway 58.

Then, the tiles 14 on the rotating body 28 of the tile stirring means 26 are sequentially sent onto the standby stand 82 of the two-tiered tile stacking means 52 by the tile takeout means 34, and the photosensor 80 of the tile guide means 50 moves the tiles 14 in front of them to When the number of passing tiles 14 reaches 34, this photosensor 80 works and the partition piece 76
The entrance 60 of the guide path 58 of the tile guide means 50 is closed by the operation. At this time, the tiles 14 are stacked in two tiers on the standby table 82. Further, when the tiles 14 are stacked in two stages on the standby stand 82 in all the two-tiered tile stacking means 52, the rotating body 28 of the tile stirring means 26 and the tile taking-out means 3
4 stops rotating with the rotating member 36.

In this state, the two-tiered tile stacking means 52 is on standby.

After the mahjong game on the top plate 12 is finished and the tiles 14 are dropped into the automatic mahjong table 10, the camshaft motor 98 is activated by operating the switch 20, and the camshaft 8
8, the standby stand 82 of the two-tiered tile stacking means 52 rises, and the sorting table 84 descends, so that the standby stand 82 and the sorting stand 84 are flush with each other, as shown by the dotted line in FIG. Move to.

Then, the pushing plate 122 of the mechanism 86 for pushing out the tiles 14 stacked in two stages on the standby stand 82 moves in the direction of the arrow in FIG. 11 to push out the tiles 14 on the standby stand 82 onto the alignment stand 84. Furthermore, the camshaft 88 rotates to raise and lower the alignment table 84 so that it is flush with the top plate 12, lower the standby table 82, and retreat the pressing plate 122, each of which is placed in the first position.
Move it to the state shown by the solid line in Figure 1. At this time, the photosensor 144 of the camshaft 88 operates to stop the rotation of the camshaft 88.

At this time, the tiles 14 are stacked in two layers and lined up on the top plate 12 as shown by the dashed line in FIG. 1, and the mahjong game is restarted again.

In this way, two sets of tiles 14 are used in the automatic mahjong table 10, and a mahjong game is played with one of the tiles 14 on the top plate 12, while the other tiles 14 are played inside the automatic mahjong table 10. It is being stirred and is waiting in two stacks. 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 an aligned state.

[Effects of the Invention] As is clear from the above description, in the present invention, the standby stand in the two-tiered tile stacking means is provided horizontally, so the tiles are placed in a good condition and the tiles do not fall or collapse. There is no risk of this happening.

In addition, the standby table, alignment table, and extrusion mechanism are each operated by a cam provided on a single camshaft.
The timing of each action works without going out of order, and the tiles stacked in two stacks will not be broken.

Furthermore, the standby table, the alignment table, and the extrusion mechanism can perform one stroke of operation just by rotating the camshaft once, which leads to labor savings in a short time. Further, only the power required to rotate the camshaft does not require any other power mechanism. Therefore, the mechanism is simple, lightweight, and economical, and the size of the automatic mahjong table as a whole does not increase.
