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 mixed 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 to let you do so.

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.

Furthermore, Japanese Patent Laid-Open No. 58-221974 proposes the following automatic mahjong table.

That is, as a means for taking out the tiles of an automatic mahjong table, a rotary disk in the shape of a bent arm or a hemispherical shape with radial protrusions formed on the surface is provided at a small interval on the underside of the top plate. A conveyance guide frame is disposed on the upper surface, and the curved protrusion of the conveyance guide is positioned near the top of the rotary disk. It consists of a mahjong tile takeout board with a magnetic material attached. As the rotary disk rotates, the tiles that have fallen onto the rotary disk are moved in the direction of the curved protrusion, that is, toward the top of the rotary disk, by the protrusions and the conveyance guide frame, and rotated to that position. It is magnetically attracted by the magnetic material of the take-out board and taken out. The tiles taken out in this way are fed into an inlet that has a notch the size of one tile in the side wall of the frame and a tile inlet guide that is protruded from the outside and serves as a tile guiding means. It has structure and function.

However, in the automatic mahjong table as described above, a considerable number of tiles are thrown off at the inlet of the frame, making it difficult to transfer the tiles smoothly and reliably.

In addition, the rotating disk, which is the bulkiest part of the automatic mahjong table, is shaped like an inverted arm or a hemisphere, and the take-out disk is installed so that it passes near the top of the rotating disk, so the entire automatic mahjong table is bulky. Become something.

[Means for Solving the Problems] In order to solve the above problems, the automatic mahjong table according to the present invention has tiles with magnets embedded in the center of the front and back sides, and a rotating body arranged below the top plate. A tile stirring means consisting of a tile stirring means, a tile taking out means comprising a rotating member having magnets arranged at two opposing places for sorting and taking in the front and back of the tiles from the tile stirring means, and a tile taking out means made of It consists of a tile guiding means for guiding tiles, and a two-tiered tile stacking means for stacking the tiles guided from the tile guiding means in two tiers and aligning them on the top plate, and the rotating body of the tile stirring means is rotated from the center. It has a circular umbrella shape or a horizontal disk shape that is slightly lowered outwardly, and the periphery of the rotating member of the tile takeout means is arranged above the periphery with an interval that allows the tiles to pass through, and the rotating member The polarity of the magnet of the tile and the magnet of the rotating member is determined so that the body periphery and the magnet provided on the rotating member rotate in the same direction and at approximately the same speed, and the back side of the tile is attracted to the lower side of the rotating member. The tile guiding means has a guiding path having a length of approximately half the outer circumference of the rotating member along the locus of the tiles attracted by the rotating member, and the tile guiding means guides the tiles passing through the guiding path. The present invention is provided with a pushing means that sequentially pushes the tiles into the insertion opening of the two-tiered stacking means in response to the removal action of the rotating member.

[Function] 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 the back side of the tiles is attracted to the lower side of the rotating member. The polarity of the magnet in the rotating member is determined, and when the tiles stirred by the tile stirring means are rotated with the back side facing up, the tiles will be attracted to the magnet of the rotating member as they are, and the tiles will be reversed. In addition, when the front side of the tile is facing upward, the magnet embedded in the tile and the magnet of the rotating member act on the rotating member to repel the front side of the tile, and also to attract the back side of the tile. The tile is rotated by itself and is attracted to the magnet of the rotating member, and the back side of the tile is turned upward by the rotating member of the tile extracting means after being stirred by the tile stirring means. In this way, the front and back sides of the tiles can be sorted and taken in, and the tiles can be transferred to the tile stacking means.

In addition, since magnets are placed at two opposing locations on the rotating member, the tiles attracted by the rotating member enter a guide path that is approximately half the length of the outer circumference of the rotating member, causing the rotating member to be taken out. Until a tile is pushed into the insertion opening of the two-tiered tile stacking means in response to this, the next tile will not enter the guideway.

Furthermore, the rotating body of the tile stirring means, which is the bulkiest part inside the automatic mahjong table, is made into a circular umbrella-shaped or horizontal disk-shaped flat body that is slightly lower outward from the center. The thickness of the device part becomes thinner.

Furthermore, since the circumferential edge of the rotary body and the magnet provided on the rotary member rotate at approximately the same speed, if the magnet and the tile come close to each other, the tile will be reliably attracted to the tile.

[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. Reference numerals 20 indicate respective switches provided on the cover plate 18 for operating the automatic mahjong table 10, and 22 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 Figure 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. Incidentally, the rotating body 28 may be a horizontal disk 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 guide means 50 (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 takeout 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 the back of the tile 14 is the rotating body 28.
If the tile is facing inward or outward, that is, tile 1
Even if the tiles 4 are placed sideways, the tiles 14 may rotate by themselves so that the back side of the tiles 14 faces upward in the same manner as described above, and may be attracted to the rotating member 36, or may be reversed by the plate 46, and the tiles 14 may be turned over by the other tile removal means 34. The tiles are attracted to the tiles and transferred to the two-tier 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.

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

As shown in FIGS. 5 to 7, this tile guide means 50 includes a board-shaped base 56 having a square protruding part formed from a semicircular part, and a flange-shaped protruding part on approximately half of its outer edge. The guide path 58 is formed of a thin plate, and is supported by a support rod 54 provided at a corner of the base 56 so as to be located between the rotary member 36 of the tile extraction means 34 and the plate 46. The lower surface of this tile guiding means 50 is arranged at approximately the same height as the rotating body 28 of the tile stirring means 26, and the shaft 44 of the tile taking out means 34 passes through the center of the semicircular portion of this base 56. ing.

The guide path 58 is formed to have a generally concave cross-section along the locus of the tiles 14 that move while being attracted to the rotating member 36, and prevents the tiles 14 from falling downward or outward. Furthermore, the entrance 60 of this guideway 58
The side is close to the periphery of the rotating body 28 of the tile stirring means 26, and the opposite side is formed with a guiding path 58 curved outward and protruding, and this protruding portion is formed as a placement part 62 for the tiles 14. , is connected to the insertion port 64 of the two-tiered tile stacking means 52 (see FIG. 7).

A magnet 66 is attached to the lower surface of the mounting portion 62, and is transferred by the rotating member 36 to the protruding piece 40 attached to the rear of the magnet 38 of the rotating member 36.
The tiles 14 that have been pushed near the placement section 62 by
I am trying to draw it to this position.

Reference numeral 68 denotes a pushing mechanism of the tile guide means 50, which sequentially pushes the tiles 14 on the placement section 62 of the guide path 58 into the insertion opening 64 of the two-tiered tile stacking means 52. The push-in mechanism 68 includes a horizontal bar 70 rotatably supported by a pin below the guide path 58, and a horizontal bar 70 that projects upward from the tip of the horizontal bar 70 and whose upper end is connected to the mounting portion 62. It is composed of a thin plate-shaped push-in piece 72 bent slightly upward toward the insertion port 64 side.

is urged toward the shaft 44 by a spring 75, and constantly presses the horizontal bar 70 against the cam 74.

The pushing mechanism 68 is operated by a horizontal bar by a cam 74 that rotates at the same time as the rotating member 36, just before the tile 14 attracted to the magnet 38 of the rotating member 36 comes onto the placement part 62 of the tile guide means 50. 70 is pushed outward and the pushing piece 72 is moved to the state shown by the solid line in FIG.
The cam 74 rotates and the horizontal bar 70 moves in the direction of the arrow in FIG. This movement pushes the tiles 14 on the placing section 62 into the insertion opening 64 of the two-tiered tile stacking means 52.

Reference numeral 76 denotes a partition piece that closes the entrance 60 side of the guideway 58, and is moved up and down by the solenoid 78. 80 is a photo sensor provided at the base 56, which detects the tile 1 passing through the guideway 58.
This is for counting the number of tiles 14 and when the 17th and 34th tiles 14 pass, the solenoid 78 is activated to move the partition piece 76 upward and close the entrance 60 side of the guideway 58. be. As a result, more than a predetermined number of tiles 14 are stored in the two-tiered tile stacking means 52.
This prevents the entry of

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.

When the tile 14, which is placed on the periphery of the rotary body 28 and is rotating, comes near the lower part of the magnet 38 attached to the rotating member 36 of the tile takeout means 34 which is rotating above it, the tile 14 embedded in the tile 14 is rotated. Due to the action of the magnet 24 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 as they are, and conversely, the backs of the tiles 14 When the magnets 24 and 38 are facing downward, the magnets 24 and 38 of the rotating member 36
38 repel each other, the tiles 14 turn over themselves and are attracted to the magnets 38 of the rotating member 36. 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 thereof, and rotates the periphery of the rotating body 28 with the tiles 14 facing up. In this way, it is attracted to the magnet 38 of the other rotating member 36.

Then, the tiles 14 are attracted to the magnet 38 of the rotating member 36 of the tile takeout means 34 and enter from the entrance 60 of the guide path 58 of the tile guide means 50, and the tiles 14 come onto the placement part 62 of the tile guide means 50. When positioned a little forward, the push-in mechanism 68 is operated by the cam 74 which rotates in the same manner as the rotating member 36, and the horizontal bar 70 is pushed outward, so that the push-in piece 72 moves to the state shown in FIG. Further, when the tiles 14 are stopped on the placement section 62, the pushing piece 72 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 rotating body 28 of the tile stirring means 26

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 sent onto the standby stand 82 of the two-tiered tile stacking means 52 by the tile takeout means 34, and the photo sensor 80 of the tile guiding 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 of the guiding path 58 of the tile guide means 50 by means of the partition piece 76. At this time, the tiles 14 are stacked in two tiers on the standby stand 82. Furthermore, when the tiles 14 are stacked in two stages on the standby tables 82 in all the two-stage tile stacking means 52, the rotation of the rotating body 28 of the tile stirring means 26 and the rotating member 36 of the tile take-out 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.

is activated to rotate the camshaft 88, and the standby table 82 of the two-tiered tile stacking means 52 is raised, and the sorting table 84 is lowered so that the standby table 82 and the sorting table 84 are flush with each other. Move to the state shown by the dotted line in Figure 11.

Then, the tiles 14 are stacked in two stages on the standby table 82.
The pressing plate 122 of the pushing mechanism 86 moves in the direction of the arrow in FIG. 11 to push out the tiles 14 on the standby table 82 onto the alignment table 84. Furthermore, the camshaft 88 rotates to raise the alignment table 84 so that it is flush with the top plate 12, lower the standby table 82, and
At the same time, the photo sensor 144 of the camshaft 88 works to move the camshaft 88 to the state shown by the solid line in FIG.

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 does not require the tiles to be in a prone state, and the tiles are attracted to the rotating member in any state; There is no need to provide a mechanism for this. Therefore, the mechanism is simple and economical. In particular, in such an automatic mahjong table, since the overall size is almost fixed, a simple mechanism is particularly advantageous in manufacturing.

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

Furthermore, since the magnets are disposed at two opposing locations on the rotating member, the next tile is guided until the tile is pushed into the insertion opening of the two-tiered tile stacking means in response to the tile removal action of the rotating member. Since the tiles do not enter the road, a sufficient distance can be maintained between the tiles, and the tiles can be transferred smoothly and reliably.

Furthermore, since the rotating body inside the automatic mahjong table is made into a circular umbrella-shaped or horizontal disk-like flat one that is slightly lower outward from the center, the thickness of the device part at the bottom of the automatic mahjong table's top plate can be reduced. be able to.

Furthermore, since the periphery of the rotating body and the magnet provided on the rotating member rotate at almost the same speed, when the magnet and the tiles come close, they will be reliably attracted, and the chances of tiles falling out are extremely reduced. Therefore, tiles can be taken out efficiently.
