Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic mahjong table, and in particular to a tile takeout means for sorting and taking in the stirred tiles by sorting the front and back sides of the tiles so that the back faces upward. It is related to.

[Prior art and its problems]

Conventionally, as an automatic mahjong table, for example,
−38220 is proposed.

In this method, tiles are buried with iron pieces biased toward the back side, laid flat, and transported by a conveyor.A disk is provided that rotates above the conveyor, and a magnet is attached to the periphery of this disk. The tiles are attracted from the conveyor by the attraction between the iron piece of the tiles and the magnet of the disc, and the tiles are transferred by a guide plate onto the conveyor toward the alignment mechanism.

At this time, it is necessary to attract and hold the tile with the front side facing down, so it is necessary to bias the iron piece to the back side of the tile, and in that case, the front side of the tile passing under the disk will If it is facing upward, it will not be attracted to the disk's magnet. For this reason, a paragraph reversal section is provided that uses the steps to turn over the tiles.This paragraph reversal section automatically flips the tiles, attracts them to another disk's magnet, and transports them by a guide plate onto a conveyor heading toward the alignment mechanism. It was designed so that

However, in the automatic mahjong table described above, after stirring the tiles, in order to transfer the tiles to the conveyor that goes to the alignment mechanism, the tiles must first be placed in a prone state, and the tiles must be placed in a prone state. However, only disks with the back side facing upward are attracted, and disks with the front side facing upward pass through the conveyor, are reversed by the stage reversing section, and are attracted to the next disk. As described above, the automatic mahjong table as described above requires a mechanism for placing the tiles in a lying position, and also requires a paragraph reversal section and a second disk.

This makes the mechanism complicated and uneconomical.
Furthermore, since the overall size of such an automatic mahjong table is almost fixed, a simple mechanism is desired.

Furthermore, since the weights are buried in the back side of the tiles, the balance of the tiles is poor, and the tiles tend to fall to the back side during competitions, and there is also a risk that the tiles stacked and arranged in two tiers may collapse.

[Means for solving problems]

The automatic mahjong table according to the present invention includes tiles in which a magnet is embedded in the center of the front and back, a tile stirring means consisting of a rotary body disposed below the top plate, and the front and back of the tiles are sorted and taken in from the tile stirring means. a tile extraction means comprising a rotating member having magnets arranged at two opposing locations;
a two-tiered tile stacking means for stacking the tiles transferred by the tile taking out means in two stages and arranging them on the top plate; are arranged at intervals that allow the tiles to pass through, and the polarities of the magnets of the tiles and the magnets of the rotating member are determined so that the back side of the tile is attracted to the lower side of the rotating member, and the rotating member The above-mentioned problem is solved by disposing a magnet below the tiles for attracting the tiles rotated by the tile stirring means and keeping them on standby.

[Effect]

In the automatic mahjong table according to the present invention, magnets are embedded in the center of the front and back of the tiles, and magnets are attached to two opposite locations of the rotating member, so that each magnet is attached so that the back side of the tile is attracted to the lower side of the rotating member. The polarity is determined and a magnet is arranged below the rotating member to attract the tiles and keep them on standby.The back side of the tiles stirred by the tile stirring means is attracted to the tile standby magnet. Or, the side of the tile is attracted to the tile waiting magnet so that the back side of the tile is facing upwards, and the tile is temporarily held in that position, and when the magnet of the rotating member rotates above it, this The back side of the tile is attracted to the magnet, and the tiles stirred by the tile stirring means are sorted by the rotating member of the tile removal means so that the back side of the tile faces upward. The tiles can be taken in and transferred to the two-tiered tile stacking means.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. As shown in FIG. is provided, and this mouth portion 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. Reference numeral 20 indicates respective switches provided on the cover plate 18 for operating the automatic mahjong table 10, and reference numeral 22 indicates support legs.

As shown in FIG. 2, the tiles 14 have a magnet 24 embedded in the center between the front and back surfaces on which characters and figures are displayed, and in this automatic mahjong table 10, these tiles 14 are The tiles 14 of the other side are stirred in 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.

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 this rotating body 28 may be a horizontal disk-shaped body as long as the rotating 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.

A magnet 46 is disposed below the rotating member 36 for attracting the tiles 14 on the rotating body 28 and keeping them on standby. Rotating body 2 at 56
It is placed on the 8th side.

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.
Decide the polarity of each magnet 38, 24 of 6 and tile 14,
In addition, the tile standby magnet 46 is connected to the rotating body 2.
The polarity of this magnet 46 and the magnet 24 of the tile 14 is determined so that the surface on the 8 side and the back surface of the tile 14 are attracted to each other. For example, if the front side of the magnet 24 of the tile 14 is the N pole and the back side is the S pole, the bottom side of the magnet 38 of the rotating member 36 and the magnet 46
and the surface on the rotating body 28 side are respectively designated as north poles. It is also possible to reverse the above N and S poles. In addition, magnet 4 for waiting tiles
Tile 1 must be placed on the surface of rotating body 28 in 6.
There is no need to arrange it so that the back side of 4 is attracted.

Therefore, as shown in FIG. 4, the tiles 14 in various states being rotated around the periphery of the rotating body 28 of the tile stirring means 26 are attracted to the tile standby magnet 46, and
Once it is on standby at that position, when the magnet 38 of the rotating member 36 rotates above it, the back side of the tiles 14 is attracted to this magnet 38, and the tiles are stacked in two stages via the tile guide means 50, which will be described later. It is transferred to means 52.

In this case, the tiles 14 whose back side faces upward or downward will rotate about 1/4 and be attracted to the tile standby magnet 46, and the tiles 14 whose back side faces the magnet 46 will remain as they are. If the tile 14 is attracted to the magnet 46 and the back side of the tile 14 is facing away from the magnet 46, the tile 14 will turn approximately half a turn and the tile standby magnet 4 will be attached.
6, or if it is not attracted, the tiles are stirred by the tile stirring means 26, and as a result, they are attracted to the tile standby magnet 46 in the same manner as described above.

In particular, regarding the tile standby magnet 46, the tile 14
The tile 1 is moved on the rotating body 28 with the back side facing upward, and the magnetic force of the tile standby magnet 46 and the tile 1
The relationship between the weight of 4 and magnet 46 and magnet 2 of tile 14
4 or the positional relationship between the magnet 46 and the upper surface of the rotating body 28, the back side of the tile 14 remains facing upward, and the side surface of the tile 14 is attached to the tile standby magnet 4.
It is particularly desirable in practice to provide the tiles 14 to be attracted to the tiles 14 more efficiently by the magnets 38 of the rotating member 36.

Moreover, the tiles 14 are not attracted to the tile standby magnet 46, but are directly attracted by the magnet 38 of the rotating member 36, and then passed through the tile guide means 50 to the tile two-tier stacking means 52.
In some cases, it may be transferred to

In this way, the front and back sides of the tiles 14 are sorted and taken in from the tile stirring means 26 by the tile takeout means 34,
The tiles can be transferred to the two-level stacking means 52. At this time, since a magnet 46 for attracting the tiles 14 on the rotating body 28 and keeping them on standby is arranged below the rotating member 36 of the tile takeout means 34, the tiles 14 attracted thereto are rotated. The member 36 is easily attracted to the magnet 38, and the tiles 14 can be taken out more efficiently.

At this time, the magnetic force of each magnet 38, 46, 24 is
Magnet 38 of rotating member 36, tile standby magnet 46,
The magnets 24 of the tiles 14 are made weaker in order.

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.

The process of arranging the tiles 14 in two stacks on the top board 12 after the end of the game using the automatic mahjong table 10 described above will be described.

After the end of the mahjong game, a switch 20 is operated to open a mouth 16 at the center of the top plate 12, and tiles 14 are dropped into the opened mouth 16.

Furthermore, by operating the switch 20, the mouth portion 16
At the same time, the motor 32 inside the automatic mahjong table 10 is operated to close the rotating body 28 of the tile stirring means 26.
and the rotating member 36 of the tile takeout means 34.

The tiles 14 dropped in this way are placed on the rotating body 28 of the tile stirring means 26.
The tiles 14 are stirred and moved around the periphery by the centrifugal force caused by the rotation and the inclination of the umbrella-shaped rotating body 28.

The tiles 14 in various states being rotated around the periphery of the rotary body 28 of the tile agitating means 26 are attracted to the tile standby magnet 46, and the tiles 14 are temporarily on standby at that position. When the magnets 38 of the tiles 14 rotate, the back side of the tiles 14 are attracted to the magnets 38 of the rotating member 36.

The camshaft 88 is stopped, the standby table 82 is placed in the state shown by the dashed line in FIG. 11, and the partition piece 76 is lowered to 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 fed onto the standby stand 82 of the two-tiered tile stacking means 52 by the tile take-out means 34, and the photo sensor 80 of the tile guide means 50 is used to When the number of tiles 14 passing in front of it reaches 34, this photo sensor 80 operates and closes the entrance 60 of the guiding path 58 of the tile guide means 50 with the partition piece 76. 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-stage stacking means 52, the rotating body 28 of the tile stirring means 26
Then, the rotation of the rotation member 36 of the tile takeout means 34 is stopped.

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

Then, the mahjong competition on the top board 12 is completed and the tiles are placed on the top board 12.

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.

〔Effect of the invention〕

As is clear from the above description, the present invention does not require the tiles to be in a prone state, and no matter what state the tiles are in, the tiles are reliably attracted to the rotating member via the tile standby magnet. There is no need to provide a mechanism for reversing the tiles, and the front and back sides of the tiles can be sorted and taken in from the tile stirring means and transferred to the tile stacking means. Therefore, the mechanism is simple and economical. Especially in such automatic mahjong tables,
Since the overall size is approximately fixed, a simple mechanism is advantageous in manufacturing.

In particular, a magnet is placed below the rotating member of the tile takeout means to attract the tiles on the rotating body and keep them on standby, so the tiles attracted here are likely to be attracted to the magnet of the rotating member , tiles can be taken out more efficiently and reliably. As a result, tiles can be stacked on two levels in a short time, leading to labor savings.

Furthermore, since a magnet is embedded in the center of the tiles, the tiles are well balanced and can prevent the tiles from falling over during the competition or from collapsing tiles stacked in two tiers.
