[0020]

According to the above-mentioned conventional configuration, there are the following problems. That is, in the conventional automatic mahjong table, since the magnets arranged in a ring on the suction ring are all in the same polarity, the mahjong tiles are not smoothly introduced from the bridge to the conveyor. A small projection made of an elastic material is provided on the lower surface of the mahjong tile, and the mahjong tile is physically pushed therefrom. For this reason, if the small projections were damaged or missing (this happens frequently), the last mahjong tiles on the bridge remained on the bridge and were not sent to the conveyor. When such a situation occurs, the start of the game is delayed, and in some cases, the start of the game is impaired.

The present invention has been made in view of the above points, and aims to increase the efficiency of Mahjong tile transport, enable reliable and quick transport of Mahjong tiles, and be necessary for starting a game. An automatic mahjong table capable of reducing time can be provided.

[0022]

In order to achieve the above object, an automatic mahjong table according to the present invention is provided as a turntable that is inclined and rotatably provided to wash a mahjong tile that has fallen through a tile dropper. And a mahjong tile, which is made of a ring-shaped member rotatably arranged above the turntable and has a built-in magnet washed on the turntable by a plurality of magnets provided downward, In an automatic mahjong table equipped with a suction ring that sucks and transports the top of the mahjong tile, the polarity of many magnets of the suction ring is the same as the polarity of the back of the mahjong tile washed on the turntable The polarity of the remaining magnets is different from the polarity of the back of the mahjong tile washed on the turntable. At this time, it is conceivable that the remaining magnets are arranged at equal intervals in the circumferential direction of the attraction ring. or,
It is conceivable that the remaining magnets are a plurality of magnets which is less than about 15% of the total number of magnets attached to the attraction ring. or,
All magnets attached to the suction ring are attached to metal inner and outer peripheral edges via metal holding members.
It is conceivable that the outer peripheral edge has the same polarity as the polarity of the magnet on the side opposite to the turntable. Further, it is considered that all magnets attached to the suction ring are approximately the same size as the mahjong tiles, and are attached with their longitudinal direction oriented along the longitudinal direction of the suction ring.

[0023]

In the present invention, for example, the last mahjong tiles carried by the suction ring but accumulated on the bridge, when the suction ring rotates and a magnet of a different polarity comes, the bridge repels the magnetic force. It is pushed further onto the conveyor, and thereby pushed into the tile feeding section. Therefore, the transport of the mahjong tiles becomes smooth.

A two-stage stacker 82 and a lever (not shown) for pushing the mahjong tiles 47 stacked in two stages onto the transport path 40 are provided.

The above is the schematic configuration of the automatic play table according to the present embodiment. The mahjong tiles 47 dropped from the play table from the fall opening are washed by the turntable 3 and are suctioned and held in a state where they are corrected to a predetermined posture by the operation of the suction ring 23. Next, it is introduced into the tile feeding unit 55 via the bridge 43, and is pushed by the tile feeding unit 55 to the two-stage stacker 82 provided at the intersection with the guiding path 39. And tile stacking
The tiles are sent out to the guiding path 39 by the sending means 80 in a state where the tiles are stacked in a two-stage manner.

Thereafter, the mahjong tiles 47 laid in four places are lifted by the lifts 45 through the window holes of the play table and pushed out onto the play table 48 to start the next game. it can.

Hereinafter, the configuration of each section will be described in detail sequentially. First, the suction ring 23 will be described with reference to FIGS. The attraction ring 23 has a ring shape as shown in the figure, and a plurality of (40 in this embodiment) permanent magnets 61 (FIG. 13) are attached thereto. In addition, each of the permanent magnets 61 is attached via a metal holding member 63 to the metal inner and outer peripheral edges 23a and 23b whose surfaces are coated with resin. The polarity of the plurality of permanent magnets 61 is such that the opposite sides are N-pole and S-pole, respectively.
Is mounted so that the S pole faces the lower surface side (the side where the turntable 3 is arranged), and the entire circumference 360
The three permanent magnets 61 located at a position of 120 ° that substantially divides the angle into three equal parts are attached such that the N poles face the lower surface side. These permanent magnets 61 attract and hold the mahjong tiles 47 washed on the turntable 3.

The size of each of the permanent magnets 61 corresponds to the size of the mahjong tile 47 shown in FIG. Each mahjong tile 47 also has a built-in permanent magnet, for example, the back (blind face) 47a of the mahjong tile 47.
Are N poles, and the surface (the surface on which various characters and patterns are engraved) 47b is an S pole. By rotating the suction ring 23 having the above configuration, the mahjong tiles 47 washed on the turntable 3 are attracted one by one by the permanent magnet 61. In other words, the mahjong tiles 47 are washed on the turntable 3 so that the back faces upward, so that the lower part of the suction ring 23 is attracted by the permanent magnet 61 having the S pole. Go. The sucked mahjong tiles 47 are introduced into the tile sending unit 55 via the bridge 43.

Each of the permanent magnets 61 is attached with its longitudinal direction extending along the circumferential direction of the attraction ring 23, thereby attracting the mahjong tiles 47 in a state of being oriented in the longitudinal direction. It has become. Further, as shown in FIG.
Since b is attached via a metal holding member 63, its polarity is the same as the polarity of the permanent magnet 61 on the side opposite to the turntable 3 (N pole in FIG. 11). Therefore, if the mahjong tile 47 is attracted in a state where the longitudinal direction of the mahjong tile 47 is not along the longitudinal direction of the permanent magnet 61, the polarity of the mahjong tile 47 is opposite to the polarities of the peripheral portions 23a and 23b of the attracting ring. Therefore, the repulsive action of the magnetic pole causes the mahjong tile 47 to rotate while being attracted,
As a result, the magnet is attracted along the longitudinal direction of the permanent magnet 63.

Next, the configuration of the bridge 43 will be described. The bridge 43 has a configuration as shown in FIGS. 1, 3, and 4. That is, a pair of bridge plates 71 and 73 are installed facing each other in an arc shape, and the bottom plate 7
5 are installed. The bridge 43 is opened so as to be in contact with the circumference of the suction ring 23, so that the mahjong tiles 47 carried by the suction ring 23 can be introduced as it is. The distance between the bridge plates 71 and 73 corresponds to the length of the mahjong tiles 47 in the width direction. Therefore, the suction ring 23 rotates and the bridge 4
3, the mahjong tiles 47 attracted to the permanent magnets 61 of the attraction ring 23 collide with the bridge plate 71, so that the mahjong tiles 47 are separated from the attraction ring 23 and conveyed from the conveyor 79 to the bridge. 43 bottom plate 7
5 fall on. At this time, for example, when the mahjong tiles 47 are attracted in a state where the longitudinal direction of the mahjong tiles 47 do not extend along the longitudinal direction of the permanent magnets 61 and are sent to the bridge 43 in a state where they are not corrected, the mahjong tiles 47 are attached to the bridge plate 71. , 7
3 falls on the turntable 3.
Then, the suction ring 2 is again passed through the turntable 3.
3 will be adsorbed.

Here, the reason why three permanent magnets 61 of different poles (N pole in the illustrated example) are provided on the attraction ring 23 will be described.
When the mahjong tiles 47 are introduced into the bridge 43 from the suction ring 23, the mahjong tiles 47 may collect on the bottom plate 75 and may not be smoothly pushed into the tile feed unit 55. That is, the mahjong tiles 47 sent one after another are pushed by the subsequent mahjong tiles 47 and pushed into the tile sending unit 55, but the last mahjong tiles that are not pushed by the subsequent mahjong tiles 47. In the case of 47,
This can happen. Conventionally, in order to prepare for such a case, a small projection is provided on the lower surface of the suction ring 23, and the accumulated mahjong tiles 47 are pushed by the small projections, whereby the tiles 47 are pushed into the tile feeding section 55. However, in the present invention, such small projections are not provided on the lower surface of the attraction ring 23, and a permanent magnet 61 having a different polarity is provided as an alternative thereto. That is, the mahjong tiles 47 accumulated on the bottom plate 75 are repelled by the magnetic force when the permanent magnet 61 of a different polarity comes, so that the bridge 43
It is further pushed onto the conveyor 79, whereby it is pushed into the tile feeding section 55.

The mahjong tiles 47 introduced to the bridge 43 are:
It is pushed into the tile sending section 55 connected to the bridge 43 as it is. The tile feeding section 55 includes a guide member 77 for guiding the mahjong tile 47, a conveyor 79 installed in the guide member 77, and a sensor 78. Mahjong tile 4 sent by the tile sending unit 55
Reference numeral 7 denotes a boundary between the corner guideway 42 shown at the lower right in FIG. 1 and the straight section guideway 41 on the left side of the guideways 39 described above, that is, the tile feeding section 55 and the guideway 39. It is transported to the intersecting site and sent to the two-stage stacker 82 constituting the tile stacking / sending means 80 separately installed there. Here, the mah-jong tiles 47 are sent into the straight section guiding path 41 in a two-tiered state. That is, the two-stage stacker 8
Numeral 2 is provided with a support plate capable of moving up and down, and when one mahjong tile 47 is introduced, it descends by a predetermined amount, and receives the next mahjong tile 47 in that state. As a result, the two mahjong tiles 47 are in a two-tiered state. Thereafter, by projecting a feeding member such as a lever, the two mahjong tiles 47 stacked in two stages are fed into the straight portion guideway 41 of the guideway 39.

Next, the structure of the swing means 49 will be described with reference to FIGS. The oscillating means 49 is installed on the lower surface side of the turntable 3, and includes a oscillating plate 81 and a plurality (five in this embodiment) mounted and fixed at appropriate positions on the oscillating plate 81. ) And the permanent magnet 83). Some of the permanent magnets 83 are disposed along the radial direction of the turntable 3, and the other permanent magnets 83 are located below the outer peripheral portion along the circumferential direction of the turntable 3 and at the lowest point of the turntable 3. It is arranged immediately before and immediately after L. The swing plate 81 is supported by a swing fulcrum 85.
A bearing 87 is attached to an eccentric position of the pulley 13 fixed to the output shaft of the drive motor 11 for rotating the turntable 3, while a long groove 89 is formed on the rocking plate 81 side. . The bearing 87 is movably engaged with the long groove 89. When the drive motor 11 rotates, the bearing 87 moves in the long groove 89, so that the swing plate 81 swings about the swing fulcrum 85. The oscillating state in the figure is indicated by a virtual line.
Each of the permanent magnets 83 has the same polarity on the turntable 3 side as the polarity on the back surface of the mahjong tile 47 (N pole in the illustrated example). 84 is a bearing mounting hole.

Here, the turntable 3 and the swinging means 49
The operation of the turntable 3 is described as follows. The turntable 3 is installed in an inclined state as shown in the figure, so that the mahjong tiles 47 dropped on the turntable 3 are turned downward from above by the rotation of the turntable 3. And the operation of moving upward again is repeated. Thereby, the mahjong tiles 47 are stirred and washed. When the turntable 3 rotates, the mahjong tiles 47 are moved to the outer periphery of the turntable 3 by centrifugal force. However, not all mahjong tiles 47 operate in such a manner. Therefore, by installing the rocking means 49, by moving the plurality of permanent magnets 83 installed there, the probability of the permanent magnets 83 and the mahjong tiles 47 meeting is increased. The action of the magnet 83 is made uniform so that the mahjong tile 47 is forcibly biased toward the outer periphery of the turntable 3. At the same time, the mahjong tile 47 is corrected by the polarity of the permanent magnet 83 so that the back surface faces upward. By these actions, the mahjong tile 47 is moved to the outer peripheral portion of the turntable 3 with its back surface directed upward, that is, in a reversed state. In such a state, the mahjong tiles 47 moved to the outer periphery of the turntable 3 are attracted one by one by the permanent magnets 61 of the attraction ring 23 described above.

FIG. 18 shows an improved example in which the arrangement of the permanent magnet 83 is devised in order to increase the reversal rate of the mahjong tiles 47. That is, some of the permanent magnets 83 are formed in a rectangular shape and are arranged radially below the bottom surface of the turntable 3.
Reference numeral 3 denotes a square, which is arranged immediately before the lowest point L of the turntable 3 in the rotation direction. Further, the other permanent magnet 83 is formed in a rectangular shape and is disposed along the outer peripheral portion 3a of the turntable 3 immediately after the lowest point L of the turntable 3 in the rotation direction. Thus, the rectangular permanent magnet 83
Are radially arranged, the rotation direction of the turntable 3 is perpendicular to the direction of rotation, and the rate of encounter with the mahjong tiles 47 is increased. At the lowest point L of the turntable 3, the mahjong tile 47
The permanent magnet 83 having a square shape is arranged immediately before the rotation direction because the magnets are hard to turn over, thereby increasing the probability that the mahjong tiles 47 and the permanent magnet 83 meet each other in the vicinity thereof. By applying a bias toward this, the reversal rate is increased. Further, by disposing a rectangular permanent magnet 83 along the outer peripheral portion 3a of the turntable 3 immediately after the rotation direction, the mahjong tile 4 that has failed to be inverted and has reached the outer peripheral portion 3a.
The aim is to extend the meeting time with No. 7 and increase the chances of reversal. Immediately after the lowest point L, the long side 91b of the guide member 91 of the tile guide body 51 is adjacent to the mahjong tile 4 guided by the tile guide body 51.
It also helps to change the orientation of 7.

A tile guide 51 is provided to assist the tile washing action by the turntable 3 and the swinging means 49.
The configuration will be described with reference to FIGS. The tile guide body 51 includes a guide member 91 and the guide member 91.
And a mounting member 95 for attaching the shaft member 93 to the shaft member 93. Guide member 91
As shown in FIGS. 19 to 21, the guide member 91 includes a short piece 91a and a long piece 91b.
An extension of a line connecting the lowermost point L of the turntable 3 to the center of the turntable 3 extends so that the long piece 91b extends to the outer peripheral portion 3a of the turntable 3 before it. It is expanded to. The angle θ between the short piece 91a and the long piece 91b is formed at about 145 ° in this example. The shaft member 93 is attached to the attachment portion 95 protruding from above in a freely movable state, whereby the guide member 91 is movable in all directions. The guide member 91 forcibly moves to the outer peripheral portion of the turntable 3 by guiding or forcibly moving a plurality of mahjong tiles 47 that are moved by the rotation of the turntable 3. Then, in combination with the operation of the swinging means 49 described above, the plurality of mahjong tiles 47 are reliably moved to the outer peripheral portion 3 a of the turntable 3.

When the mahjong tile 47 is guided along the short piece 91a and the long piece 91b of the guide member 91, for example, the mahjong tile 47 has its longitudinal direction set to the short piece 91a and the long piece 91b. Will be guided along. Then, as shown in FIG. 19, when the mahjong tile 47 is separated from the tip of the long piece 91b, the mahjong tile 47 is rotated by 90 ° in combination with the rotating action of the turntable 3, whereby the mahjong tile 47 is rotated. The direction is changed, and the mahjong tiles 47 are positioned on the outer peripheral portion of the turntable 3 with the longitudinal direction thereof along the circumferential direction of the turntable 3. That is, the state is corrected so that the suction by the suction ring 23 is performed normally.

At this time, the mahjong tile 47 is inserted into the long piece 91b.
When the tip of the is pushed, the guide member 91
19 (in the direction of the arrow in FIG. 19), the short piece 91a also rotates in the direction of the arrow. This short piece 91
In the turning power a, since the short piece 91a is shorter in length than the long piece 91b, the torque is large. For this reason, if there is a mahjong tile 47 in the center of the turntable 3 (this mahjong tile 47
Is weak because of the effect of the centrifugal force on the mahjong tile 47), but this mahjong tile 47 is pushed by the short piece 91a,
It will fall to the outer periphery of the turntable 3. Thus, the mahjong tiles 47 are smoothly attracted to the attraction ring 23.

Next, the configuration of the tile transport mechanism 53 will be described with reference to FIGS. 1, 2, 22, and 23. As shown in FIG. 22, the tile transport mechanism 53 includes a chain 101 disposed endlessly in a guiding path 39. The chain 101 includes three chains 101 installed at four corners. Roller 1
03 and tensioner 10 installed in place of roller
It is hung over two. And any of the rollers 103
The rotation is transmitted from a drive motor 104 (shown in FIG. 1), whereby the chain 101 rotates in a loop. Further, as shown in FIG. 23, tile transport pins 105 are attached to the places where the chain 101 is divided into four equal parts so as to protrude upward. These four tile transport pins 105 are attached in a state of being directly inserted into the holes of the link plate of the chain 101.

The mounting structure of the tile transport pin 105 will be described in comparison with a conventional configuration. The conventional configuration is as shown in FIGS.
Looking at the lengths of the four sides of 1 ', the length of a' is set to be slightly longer than the length of other b ', c', and d '. In addition to the four rollers 103 ', a tension roller 103 "is provided. Of the four tile transport pins 105', three of the tile transport pins 105 'are a chain. Although it is inserted into the hole of the link board 101, the remaining one is
As shown in FIG. 25, the chain 101 ′ cannot be inserted into the hole of the link plate for the sake of adjusting the length,
It is welded and fixed in place. for that reason,
Although the welded tile transporting pin 105 'was damaged, in the present embodiment, all the tile transporting pins 10' were damaged.
5 is attached and fixed by insertion, so there is no such concern.

The bottom surface of the turntable 3 is shown in FIG.
As shown in (1), the cross section is formed to be bent, and the horizontal portion 4 is partially formed. This is because the mahjong tile 47
Can be placed here, so that when the turntable 3 rotates, it can be easily carried upward from below.
However, the shape of the bottom surface of the turntable 3 is arbitrary,
It is not necessary to be formed so as to be bent in cross section as in the illustrated example. For example, a horizontal or mortar-shaped cross section, an inverted mortar-shaped cross section, or the like can be considered. As shown in FIG. 1, a plate-shaped direction control plate 107 is provided on the wall surface of the tile washing hopper of which the turntable 3 forms a part, and the mahjong tiles 47 sucked and held by the suction ring 23. Is corrected so that the direction is the predetermined direction.

The operation will be described based on the above configuration. First, the game of one game is finished on the upper surface of the play table, and the mahjong tiles 47 are dropped from the drop opening of the play table. The dropped mahjong tile 47 is a turntable 3,
The tile is washed by the swinging means 49 and the tile guide body 51, and is sucked and held in a state corrected to a predetermined posture by the operation of the suction ring 23.

Then, it is introduced into the bridge 43 and pushed into the position of the two-stage stacker 82 by the tile feeding section 55, and the tile stacking / sending means 80 is the first straight section of the guide path 39. The sheets are sequentially fed into the inside 41 in a two-stage state. When the number of mahjong tiles 47 sent into and aligned in the straight section guiding path 41 of the guiding path 39 reaches a predetermined tiled state, the drive motor 1
The rotation of the chain 101 by the operation of the 04 moves the tile transport pins 105 by a distance corresponding to the distance between them, and the first linear section of the guide path 39 (the linear section shown in the lower part of FIG. A predetermined number of mahjong tiles 47 arranged on the taxiway I) are passed through the corner taxiway 42 to the next second straight-line taxiway 41 (the straight-line taxiway II shown on the left in FIG. 1). Extrude in. Thereby, the first straight section taxiway 4
1 will be empty.

Next, new mahjong tiles 47 are sequentially fed into the empty first-place straight section guiding path 41 in a two-tiered state. When the number of Mah-jong tiles 47 sent and aligned reaches a predetermined tile-laying state, the rotation of the chain 101 by the operation of the drive motor 104 causes the tile transport pins 105 to move the tiles. The Mahjong tiles 47 moved by a distance corresponding to the interval and arranged in the second straight section guideway 41 of the second guideway 39 are moved to the next third straight section guideway 41 (shown in the upper part of FIG. 1). Straight section taxiway III)
And the mahjong tiles 47 aligned with the first straight section guideway 41 of the guideway 39 are pushed out into the next second straight section guideway 41, thereby forming the first straight line. The partial guiding path 41 is emptied.

Next, new mahjong tiles 47 are sequentially fed into the empty first place straight guideway 41 in a two-tiered state. When the number of Mah-jong tiles 47 sent and aligned reaches a predetermined tile-laying state, the chain 101 is activated by the drive motor 104.
The tile transport pins 105 are moved by a distance corresponding to the distance between them, and the mahjong tiles 47 arranged in the third straight section guideway 41 of the guideway 39 are moved to the next fourth place. Of the straight section taxiway 41 (the straight section taxiway I shown on the right side of FIG. 1)
V), and the mahjong tiles 47 arranged in the second straight section guideway 41 of the guide path 39 are pushed out into the next third straight section guideway 41, and the third magnificent tile 47 is pushed out of the guideway 39. The mahjong tiles 47 arranged in the first straight section taxiway 41 are pushed out into the next second straight section taxiway 41, so that the first straight section taxiway 41 is empty. And

Finally, new mahjong tiles 47 are sequentially fed into the empty first straight section guiding path 41 in a two-tiered state. When the number of Mah-jong tiles 47 to be sent and aligned reaches a predetermined tile-laying state, the operation of building the Mah-jong tiles 47 at positions adjacent to the lifts 45 is completed. Become. After that, the mahjong tiles 47 laid at four locations are first pushed out onto the elevating platform 50 by each lift 45, and in this state, the elevating platform 50 is raised through each window hole, and the mahjong tiles 47 are removed. It can be pushed out onto the play table 48 so that the next game can be started.

As described above, according to the above-described embodiment, the mahjong tiles 47 accumulated on the bottom plate 75 of the bridge 43 are not attached to the suction ring 23 because the magnets having different polarities are arranged in the suction ring. When the rotating permanent magnet 61, that is, the N pole comes, the back 47a of the mahjong tile 47 becomes the N pole.
Due to the repulsion of the magnetic force, the conveyor 79 is moved from the bridge 43.
It is pushed upward, whereby it is pushed into the tile sending unit 55. Therefore, the Mahjong tiles can be transported reliably and quickly.

The present invention is not limited to the above embodiment. For example, the magnet having different polarity mixed and arranged on the suction ring is optional as long as both the transfer efficiency of the mahjong tile and the pushing effect of the mahjong tile are satisfied. That is, as a rule of thumb, if the number of magnets exceeds about 15% of the total number of magnets (the number of magnets is 7 or more in the above embodiment), the transfer efficiency is extremely deteriorated. Therefore, the number may be two or four within the above range. Also, although the arrangement of the magnets of different polarities is desirably at equal intervals, it is basically arbitrary. However, since the turntable is rotating at a constant speed, if the magnets of different polarities are arranged at regular intervals, the efficiency of pushing the magnet to the conveyor is higher than that of the bridge. Further, the type of magnet is not limited.

[0052]

As described in detail above, according to the automatic mahjong table according to the present invention, the transfer efficiency of mahjong tiles is improved, the mahjong tiles can be transported reliably and quickly, and the time required to start the game is reduced. be able to.
