[0020]

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

The present invention has been made in view of the above points, and an object of the present invention is to improve the transportation efficiency of mahjong tiles, to enable reliable and speedy transportation of mahjong tiles, and to start the game. It is possible to provide an automatic mahjong table that can reduce the time.

[0022]

In order to achieve the above object, an automatic mahjong table according to the present invention is a turntable which is tilted and is rotatably provided to wash mahjong tiles dropped through a tile drop opening. And a back side of a mahjong tile that is composed of a ring-shaped member that is rotatably arranged above the turntable and that has magnets washed on the turntable by a plurality of magnets provided downward. In an automatic mahjong table equipped with an adsorbing ring for adsorbing and transporting with the top facing up, many magnets of the adsorbing ring have the same polarity as the back surface of the mahjong tiles washed on the turntable. , The remaining magnets have a polarity different from that of the back of the mahjong tiles 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 attached to the attraction ring, which is less than about 15% of the total number of magnets. or,
All the magnets attached to the adsorption ring are attached to the inner and outer peripheral edge parts made of metal through a metal holding member.
It is conceivable that the outer peripheral edge has the same polarity as that of the magnet on the side opposite to the turntable. Further, it is conceivable that all the magnets attached to the adsorption ring are approximately the same size as the mahjong tiles and are attached with their longitudinal directions oriented along the longitudinal direction of the adsorption ring.

[0023]

In the present invention, for example, the last mah-jong tile that has been carried by the suction ring but accumulated on the bridge is the bridge due to the repulsion of the magnetic force when the suction ring rotates and a magnet with a different polarity comes. It is pushed further onto the conveyor, which in turn pushes it into the tile feeder. Therefore, the transportation of mahjong tiles will be smooth.

(Shown in FIG. 4), and is pushed up to the play table 48 through the lifting table 50 that is raised and lowered to the same position, and is pushed out onto the play table 48. As a result, the game can be started. Further, the swinging means 49 is attached to the lower surface side of the turntable 3 described above. Further, a tile guide body 51 is attached to the upper surface side of the turntable 3. A tile transport mechanism 53 for transporting the mahjong tiles 47 is provided on the taxiway 39 near the corner taxiway 42 in the upper right of FIG. Further, a tile stacking / feeding means 80, which will be described later, is installed at the boundary between the lower right corner taxiway 42 and the left straight part taxiway 41, and the mahjong tiles 47 are stacked in two stages there. A two-layer stacker 82 and a lever (not shown) for pushing out the mahjong tiles 47 stacked in two layers to the transport path 40 are installed.

The above is the schematic configuration of the automatic play table according to the present embodiment. The mahjong tile 47 dropped from the play table through the drop port is washed by the turntable 3 and is attracted and held in a state where it is corrected to a predetermined posture by the operation of the attraction ring 23. Next, it is introduced into the tile feeding section 55 through the bridge 43, and is pushed by the tile feeding section 55 to the two-stage stacker 82 provided at the intersection with the guide path 39. And pile up
It is sent out to the guide path 39 in a state of being stacked in two layers by the sending means 80, and by the tile transfer mechanism 53,
It is appropriately conveyed in the guide way 39, and a predetermined number of mahjong tiles 47 are tiled at the positions of the respective straight guide ways 39a of the guide way 39. After that, the mahjong tiles 47, which have been tiled at four places, are lifted by the lifts 45 through the windows of the play table and pushed out onto the play table 48 to start the next game. it can.

The configuration of each section will be described in detail below. First, the suction ring 23 will be described with reference to FIGS. 9 to 11. The attraction ring 23 has a ring shape as shown in the drawing, and a plurality of (40 in the case of this embodiment) permanent magnets 61 (FIG. 13) are attached thereto. Further, each of the permanent magnets 61 is attached to the metal inner / outer peripheral edge portions 23a and 23b whose surfaces are resin-coated via a metal holding member 63. Regarding the polarities of the plurality of permanent magnets 61, the opposite sides are the N pole and the S pole.
Is attached so that the S pole is directed to the lower surface side (the side where the turntable 3 is arranged), and the entire circumference 360
Regarding the three permanent magnets 61 located at a position of 120 °, which divides the angle into three substantially equal parts, the N pole is attached so that the N pole is directed to 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 is the size corresponding to that of the mahjong tile 47 shown in FIG. Further, each mahjong tile 47 also has a built-in permanent magnet, for example, the back surface (blind surface) 47a of the mahjong tile 47.
Is the N pole, and the surface (the surface on which various characters and patterns are engraved) 47b is the S pole. By rotating the attraction ring 23 having the above structure, the mahjong tiles 47 washed on the turntable 3 are attracted by the permanent magnet 61 one by one. That is, the mahjong tile 47 is washed on the turntable 3 so that the back surface of the mahjong tile 47 faces upward, so that the bottom of the attraction ring 23 is attracted by the permanent magnet 61 having the S pole. Go. The sucked mahjong tile 47 is introduced into the tile feeding section 55 via the bridge 43.

Further, each permanent magnet 61 is attached with its longitudinal direction aligned with the circumferential direction of the attraction ring 23, whereby the mahjong tile 47 is attracted in the state of being oriented in the longitudinal direction. It is like this. Also, as shown in FIG. 11, the inner and outer peripheral edge portions 23a, 23 of the suction ring 23 are
Since b is attached via the 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 it is assumed that the mahjong tiles 47 are attracted in a state where the longitudinal direction of the mahjong tiles 47 does not follow the longitudinal direction of the permanent magnet 61, the polarities of the mahjong tiles 47 will be opposite to the polarities of the peripheral portions 23a and 23b of the adsorption rings. Therefore, due to the repulsive action of the magnetic poles, the mahjong tiles 47 will rotate while being attracted,
Eventually, the permanent magnet 63 is attracted in a state along the longitudinal direction.

Next, the structure of the bridge 43 will be described. The bridge 43 has a structure as shown in FIGS. 1, 3, and 4. That is, a pair of bridge plates 71 and 73 are installed so as to face each other in an arc shape, and the bottom plate 7 is provided on the lower surface between them.
5 are installed. The bridge 43 is opened so as to be in contact with the circumference of the suction ring 23, and the mahjong tile 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 tile 47 in the lateral direction. Therefore, the suction ring 23 rotates and the bridge 4
When passing through 3, the Mahjong tiles 47 attracted to the permanent magnet 61 of the attraction ring 23 will collide with the bridge plate 71, so that the Mahjong tiles 47 are separated from the attraction ring 23 and on the conveyor 79 or the bridge. 43 bottom plate 7
5 fall on. At this time, for example, when the mahjong tile 47 is adsorbed in a state in which the longitudinal direction of the permanent magnet 61 does not follow the longitudinal direction and is sent to the bridge 43 without being corrected, the mahjong tile 47 is bridged by the bridge plate 71. , 7
It hits 3 and falls to the turntable 3.
Then, again through the turntable 3, the suction ring 2
3 will be adsorbed.

Here, the reason why the attraction ring 23 is provided with three permanent magnets 61 having different poles (N poles in the illustrated example) will be described.
When being introduced into the bridge 43 from the suction ring 23, the mahjong tiles 47 may accumulate on the bottom plate 75 and may not be smoothly pushed into the tile feeding portion 55. That is, the Mahjong tiles 47 sent one after another are pushed by the succeeding Mahjong tiles 47 and are pushed into the tile feeding section 55, but the last Mahjong tiles 47 which are not pushed by the succeeding Mahjong tiles 47. For 47,
This can happen. In the past, in preparation for such a case, a small projection is provided on the lower surface of the suction ring 23, and the mahjong tiles 47 accumulated by the small projections are pushed and thereby pushed into the tile feeding portion 55. However, in the present invention, such a small protrusion is not provided on the lower surface of the attraction ring 23, and instead of this, the permanent magnet 61 of the different pole is made to exist. That is, the mahjong tiles 47 accumulated on the bottom plate 75, when the permanent magnets 61 of different polarities come, are repelled by the magnetic force to repel the bridge 43.
It is pushed onto the conveyor 79, and thus pushed into the tile feeding section 55.

The Mahjong tile 47 introduced into the bridge 43 is
As it is, it is pushed into the tile feeding section 55 connected to the bridge 43. 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 tiles 4 sent by the tile sending unit 55
7 is a boundary portion between the corner guide passage 42 shown at the lower right of FIG. 1 and the straight portion guide passage 41 on the left side of the guide passage 39 already described, that is, the tile feeding portion 55 and the guide passage 39. It is transferred to the intersecting portion and is sent to the two-stage stacker 82 that constitutes the stacking / sending means 80 separately installed there. Here, the mahjong tiles 47 are placed in a two-tiered state and fed into the straight line guide path 41. That is, the two-stage stacker 8
2 has a support plate movable up and down, and when one mahjong tile 47 is introduced, it descends by a predetermined amount and receives the next one mahjong tile 47 in that state. As a result, the two mahjong tiles 47 are in a two-tiered state. After that, the two feeding mahjong tiles 47 are fed into the straight line guide path 41 of the guide path 39 by projecting a feeding member such as a lever.

Next, the structure of the swinging means 49 will be described with reference to FIGS. 14 to 18. The oscillating means 49 is installed on the lower surface side of the turntable 3, and includes an oscillating plate 81 and a plurality of (5 in the case of this embodiment) mounted / fixed at appropriate positions on the oscillating plate 81. ) And a permanent magnet 83). A part of the permanent magnets 83 is arranged along the radial direction of the turntable 3, and the other permanent magnets 83 are below the outer peripheral portion along the circumferential direction of the turntable 3 and are the lowest points of the turntable 3. It is arranged immediately before and 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 side of the swing plate 81. . The bearing 87 is movably engaged with the long groove 89. Then, as the drive motor 11 rotates, the bearing 87 moves in the long groove 89, so that the swing plate 81 swings around the swing fulcrum 85. The oscillating state in the figure is shown by an imaginary line.
Further, 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). Reference numeral 84 is a bearing mounting hole.

Here, the turntable 3 and the swing means 49
The operation of the turntable 3 is installed in an inclined state as shown in the figure. Therefore, the mahjong tiles 47 dropped on the turntable 3 are moved downward from above by the rotation of the turntable 3. The operation of moving to and moving upward again is repeated. As a result, the mahjong tiles 47 are agitated and washed. When the turntable 3 rotates, the mahjong tiles 47 are moved to the outer peripheral portion of the turntable 3 by centrifugal force, but not all the mahjong tiles 47 operate that way. Therefore, by installing the swinging means 49, by moving a plurality of permanent magnets 83 installed therein, the probability that the permanent magnets 83 and the mahjong tiles 47 meet will be increased, and the mahjong tiles 47 will be permanent. The magnet 83 is made uniform in operation, whereby the mahjong tile 47 is forcibly biased toward the outer peripheral side of the turntable 3. At the same time, the polarity of the permanent magnet 83 corrects the mahjong tile 47 so that its back surface faces upward. By these actions, the mahjong tile 47 is moved to the outer peripheral portion of the turntable 3 with the back surface thereof directed upward, that is, in the inverted state. In this state, the mahjong tiles 47 moved to the outer peripheral portion of the turntable 3 are attracted one by one by the permanent magnet 61 of the attraction ring 23 already described.

FIG. 18 shows an improved example in which the arrangement of the permanent magnets 83 is devised in order to increase the inversion rate of the mahjong tile 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, and the other permanent magnets 8 are
3 is formed in a square shape and is arranged immediately before the lowest point L of the turntable 3 in the rotational direction. Furthermore, the other permanent magnet 83 is formed in a rectangular shape and is arranged along the outer peripheral portion 3 a of the turntable 3 immediately after the lowest point L of the turntable 3 in the rotational direction. Thus, the rectangular permanent magnet 83
If they are arranged in a radial pattern, they will be orthogonal to the rotation direction of the turntable 3, so the rate of encountering the mahjong tiles 47 will increase. At the lowest point L on the turntable 3, Mahjong tiles 47
Since it accumulates and is difficult to reverse, a square permanent magnet 83 is arranged immediately before the rotation direction, thereby increasing the probability that the mahjong tile 47 and the permanent magnet 83 will meet in the vicinity of the square permanent magnet 83. By urging it toward, the inversion rate is increased. Furthermore, by arranging the rectangular permanent magnets 83 along the outer peripheral portion 3a of the turntable 3 immediately after the rotation direction, the mahjong tile 4 which has failed to reverse and reaches the outer peripheral portion 3a 4
The meeting time with 7 will be extended and the chance of reversal will be increased. Immediately after this lowest point L, the long side 91b of the guide member 91 of the tile guide body 51 is adjacent, so that this permanent magnet 83 is guided by the tile guide body 51.
It also helps to change the direction of 7.

There is a tile guide body 51 for assisting the washing action by the turntable 3 and the swinging means 49.
The configuration will be described with reference to FIGS. 19 to 21. The tile guide body 51 includes a guide member 91 and the guide member 91.
Is composed of a shaft member 93 which is a coil spring and which is vertically installed right above the turntable 3, and a mounting piece 95 for mounting the shaft member 93. The guide member 91
As shown in FIGS. 19 to 21, is composed of a short piece 91 a and a long piece 91 b, and the center 9 of the guide member 91.
The extension of the line connecting 2 and the lowest point L of the turntable 3 is directed toward the center of the turntable 3, and the long piece 91b is extended to the outer peripheral portion 3a of the turntable 3 before the "he" shape. Be expanded to. The angle θ between the short piece 91a and the long piece 91b is formed to be about 145 ° in this example. Then, the shaft member 93 is movably attached to the attachment portion 95 arranged so as to project from above, whereby the guide member 91 is movable in all directions. The guide member 91 is for guiding or forcibly moving the plurality of mahjong tiles 47 that move by the rotation of the turntable 3, thereby forcibly moving them to the outer peripheral portion of the turntable 3. And, together with the action of the swinging means 49 already described, the plurality of mahjong tiles 47 are surely moved to the outer peripheral portion 3a of the turntable 3.

The operation of the tile guide body 51 will be further described. When the mahjong tile 47 is guided along the short piece 91a and the long piece 91b of the guide member 91, the mahjong tile 47 is, for example, in the longitudinal direction, the short piece 91a and the long piece 91b. Will be guided along with. 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 tile 47 is located on the outer peripheral portion of the turntable 3 with its longitudinal direction aligned with the circumferential direction of the turntable 3. That is, the suction ring 23 is corrected to a state in which the suction is normally performed.

At this time, that is, the mahjong tile 47 is attached to the long piece 91b.
When the tip of the turntable pushes the guide member 91.
Since it rotates in the direction of rotation of the arrow (arrow direction in FIG. 19), the short piece 91a also rotates in the arrow direction. This short piece 91
The turning force of a has a large torque because the short piece 91a is shorter than the long piece 91b. Therefore, if there is a mahjong tile 47 in the center of the turntable 3 (this mahjong tile 47
However, the mahjong tile 47 is pushed by the short piece 91a.
It will fall to the outer periphery of the turntable 3. In this way, the mahjong tile 47 is smoothly attracted to the attraction ring 23.

Next, the construction of the tile transfer mechanism 53 will be described with reference to FIGS. 1, 2, 22, and 23. As shown in FIG. 22, the tile transfer mechanism 53 includes a chain 101 arranged in an endless manner in the guide path 39, and the chain 101 has three chains 101 installed at four corners. Laura 1
03 and tensioner 10 installed instead of rollers
It has been passed over to 2. Then, one of the rollers 103
The rotation is transmitted from the drive motor 104 (shown in FIG. 1) to the chain 101, which causes the chain 101 to rotate in a loop. Further, as shown in FIG. 23, a tile conveying pin 105 is attached to the place where the chain 101 is divided into four equal parts in a state of protruding upward. The four tile transfer 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 transfer pin 105 will be described in comparison with the conventional structure. The conventional structure is as shown in FIGS. 24 and 25.
Looking at the lengths of the four sides of 1 ', the length of a'is set to be slightly longer than the other b', c ', and d'. The tension roller 103 ″ is provided in addition to the four rollers 103 ′. And, among the four tile transfer pins 105 ′, three tile transfer pins 105 ′ are chains. Although it is inserted in the hole of the link board of 101, about the remaining one,
As shown in FIG. 25, for the convenience of adjusting the length of the chain 101 ′, it cannot be inserted into the hole of the link plate,
It is welded and fixed in place. for that reason,
Although the damage of the welded tile transfer pins 105 ′ was a problem, in the case of this embodiment, all the tile transfer pins 10 ′.
Since 5 is attached and fixed by inserting, there is no such concern.

The bottom surface of the turntable 3 described above is shown in FIG.
As shown in FIG. 5, the cross section is formed to be bent, and the horizontal portion 4 is formed in a part. This is Mahjong tile 47 if there is a horizontal part 4.
This is because it can be placed here, and when the turntable 3 rotates, it can be easily carried from above to below.
However, the shape of the bottom surface of the turntable 3 is arbitrary,
It may not be formed by bending the cross section as in the illustrated example. For example, a horizontal shape, a mortar shape in cross section, an inverted mortar shape in cross section, or the like can be considered. Further, as shown in FIG. 1, a plate-shaped direction control plate 107 is provided on the wall surface of the washing hopper of which the turntable 3 constitutes a part thereof, and the mahjong tile 47 is sucked and held by the suction ring 23. Correct so that the direction of is in the specified direction.

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

Next, 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 first straight line guide path of the guide path 39 by the tile stacking / feeding means 80. It is sequentially fed into 41 in a two-tiered state. Then, when the number of aligned mahjong tiles 47 fed into the straight portion guide passage 41 of the guide passage 39 and aligned reaches a predetermined number of tiles, the drive motor 1
The rotation of the chain 101 by the operation of 04 causes the tile conveying pins 105 to move by a distance corresponding to the distance between them, and the first straight portion of the guide passage 39 (the straight portion shown in the lower part of FIG. 1). A predetermined number of mahjong tiles 47 lined up in the taxiway I) are passed through the corner taxiway 42 and the next second straight part taxiway 41 (the straight part taxiway II shown on the left side of FIG. 1). Push it out. Thereby, the first straight line taxiway 4
1 is empty.

Next, new mah-jong tiles 47 are sequentially fed in a two-tiered state to the empty first straight line guideway 41. Then, when the number of aligned mahjong tiles 47 that have been sent and aligned reaches a predetermined number of tiled tiles, rotation of the chain 101 due to operation of the drive motor 104 causes the tiles 105 for tile tile transfer to move to those tiles. The mahjong tiles 47, which are moved by a distance corresponding to the distance and are aligned in the second straight line guideway 41 of the guideway 39, are moved to the next third straight line guideway 41 (shown in the upper part of FIG. 1). Straight line taxiway III)
The mahjong tiles 47 aligned with the first straight line guideway 41 of the taxiway 39 are pushed out into the next second straight line guideway 41, whereby the first straight line is formed. The partial taxiway 41 is emptied.

Next, new mahjong tiles 47 are successively fed in a two-tiered state into the emptied first straight line guideway 41. Then, when the number of aligned mahjong tiles 47 that have been sent and aligned reaches a predetermined number of tiles, the chain 101 is operated by the drive motor 104.
The rotation of the tiles causes the tile conveying pins 105 to move by a distance corresponding to the distance between them, and the mahjong tiles 47 aligned in the third straight line guide path 41 of the guide path 39 are moved to the next fourth Straight part taxiway 41 (the straight part taxiway I shown on the right side of FIG.
V) and the mahjong tiles 47 aligned in the second straight portion taxiway 41 of the taxiway 39 are extruded into the next third linear portion taxiway 41, and The mahjong tiles 47 aligned in the first straight portion taxiway 41 are pushed into the next second straight portion taxiway 41, whereby the first straight portion taxiway 41 is empty. And

Finally, new mahjong tiles 47 are sequentially fed in a two-tiered state into the empty first straight line guideway 41. Then, when the number of aligned mahjong tiles 47 that have been sent and arranged reaches a predetermined tiled state, the operation of tiled mahjong tiles 47 at a position adjacent to each lift 45 is completed. Become. After that, the mahjong tiles 47, which have been tiled in four places, are first pushed out by the lifts 45 onto the elevating table 50, and in this state, the elevating table 50 is raised through each window hole, and at the same time, the mahjong tiles 47 are removed. It only has to be pushed onto the play table 48 so that the next game can be started.

As described above, according to the above-mentioned embodiment, since the magnets having different polarities are mixedly arranged in the suction ring, the Mahjong tile 47 accumulated on the bottom plate 75 of the bridge 43 has the suction ring 23. When the permanent magnet 61 having a different polarity, that is, the N pole comes to rotate, the back surface 47a of the mahjong tile 47 becomes the N pole,
Due to the repulsive action of magnetic force, the conveyor 79
It is pushed upward, and as a result, it is pushed into the tile feeding section 55. Therefore, the mahjong tiles can be transported reliably and promptly.

The present invention is not limited to the above embodiments. For example, the magnets having different polarities mixed and arranged in the attraction ring are optional as long as they satisfy both the transportation efficiency of the mahjong tiles and the pushing effect of the mahjong tiles. That is, as a rule of thumb, when the number of magnets exceeds about 15% (7 or more in the above embodiment), the transport efficiency is extremely deteriorated. Therefore, within the above range, the number may be two or four. Further, although it is desirable that the magnets of different poles are arranged at equal intervals, basically they are arbitrary. However, since the turntable is rotating at a constant speed, the efficiency of pushing the magnets of different poles to the conveyor is higher than that of the bridge when the magnets of different poles are arranged at equal intervals. Further, the type of magnet does not matter.
