Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic mahjong table that uses magnets to arrange mahjong tiles in a hopper of a tile supply device and send them out to a sorting section after arranging them in a certain shape. Regarding improvements to mahjong tiles used for.

As shown in FIG. 1, the automatic mahjong table A is located below the mahjong table 1, which has an opening/closing opening 10 in the center and a lift 11 that moves up and down on the four sides, as shown in FIG. There is an automatic mahjong tile sorting machine a like this one. When a game is played using this automatic mahjong table A, the mahjong tiles are transferred to the tile supply device 20 of the automatic mahjong tile arrangement machine a by opening the opening/closing port 10 each time one game is completed. The tiles are dropped into the hopper 21, cleaned in the hopper 21, arranged in a fixed posture, and sequentially supplied from the tile supply device 20 to the alignment section 12, where they are transferred to the upper surface of each lift 11. The mahjong table 1 is then pushed up to the top surface of the mahjong table 1 by the lift 11 and used again for the game.

By the way, the automatic mahjong table A has a tile supply device 20 configured to receive the mahjong tiles that have fallen from the opening/closing opening 10 of the mahjong table 1, wash the tiles, arrange them in a certain posture, and send them to the alignment section 12. To construct the hopper 21, as shown in FIG. In this case, an annular suction ring 24 that overlaps the upper surface of the peripheral edge 23a of the table 23 in a plan view is arranged in a horizontal state, and magnets K are arranged and attached in an annular manner on the lower surface side of the adsorption ring 24. In addition, a piece of iron is embedded in the mahjong tile 3 in a part close to the top side of the mahjong tile 3, and the iron piece inside the mahjong tile 3 is attracted by the suction ring 24, so that the mahjong tile 3 maintains a certain posture. Furthermore, there is a configuration in which the material is attracted to the suction ring 24, carried out by the rotation of the ring 24, and supplied to the alignment section 12.

The mahjong tiles targeted in the present invention are the mahjong tiles used in the automatic mahjong table A of this type.

Therefore, in the past, the mahjong tiles used in the automatic mahjong table of the above-mentioned form had an iron piece buried inside the outside of the back side to be attracted to the suction ring 24 having a magnet on the bottom side. When the mahjong tiles 3 are placed face down with the front side up and adsorbed to the bottom surface of the suction ring 24, the front side becomes the top side.
When the mahjong tile 3 is attracted to one of the magnets K arranged annularly on the lower surface side of the attraction ring 24, the longitudinal direction of the mahjong tile 3 crosses a predetermined direction. Therefore, a separate means for correcting this posture is provided.

An object of the present invention is to provide a mahjong tile in which the longitudinal direction of the suctioned mahjong tile is automatically and reliably corrected in a predetermined direction when the mahjong tile is suctioned to this suction ring.

In order to achieve this objective, the present invention heat-fuses the surface body on the molded back body, and creates a channel shape inside the synthetic resin mahjong tile that is molded into an integrated mahjong tile. A pair of bent side walls of the channel-shaped iron piece that surrounds the magnetic body overlaps the inner surface of the iron piece to divide the magnetic poles and change the direction of the magnetic pole. A mahjong tile for use in an automatic mahjong table has been developed which is characterized by being buried parallel to the sides and with each free end of the pair of side walls facing the back or front surface of the mahjong tile.

Next, the present invention will be explained in detail with reference to the drawings.

In FIGS. 4 to 7, reference numeral 3 represents a mahjong tile according to the present invention which is molded from a synthetic resin material, has a back surface body 30 and a surface body 31 which are heat treated and integrally formed by die molding. The magnetic body 5 formed in the shape of a long prism in the front-rear direction (longitudinal direction) of the mahjong tile 3 is
As shown in FIGS. 5 and 7, they are buried inside an iron piece 4 which is bent into a shallow channel shape when viewed from the front, so that the magnetic poles are divided and the direction of the magnetic poles is changed by overlapping each other. The buried position of the magnetic body 5 is a joint site where the back body 30 and the front body 31 are overlapped and joined, and is usually the position of a weight buried inside a mahjong tile. The buried state of the magnetic body 5 is such that each free end of the pair of bent side walls 40, 40 of the iron piece 4 is formed into a channel shape so as to overlap the magnetic body 5 and surround the magnetic body 5. However, as shown in FIG. 5, when viewed from the front side, which is the short side of the mahjong tile 3, the molded mahjong tile 3 is placed close to the left and right side edges of the mahjong tile 3. It is set to face the outer surface side of the back surface body 30, which becomes the back surface 3a, so that the pair of bent side walls 40, 40 of the channel-shaped iron piece 4 where one magnetic pole N overlaps The magnetic body 5 is divided into free ends N, N, and the direction of the divided magnetic poles N, N is aligned with the direction of the other magnetic pole S. It is buried in the mahjong tile 3 with its direction facing the back surface 3a of the mahjong tile 3.

The magnetic material 5 embedded in the mahjong tiles 3 is
Contrary to the above-mentioned case, there is a case where the free ends of the pair of bent side walls 40, 40 of the channel-shaped iron piece 4 that overlaps with the iron piece 4 are buried in such a manner that they face the surface 3b of the mahjong tiles 3. In addition, the pair of bent side walls 40, 40 of the channel-shaped iron piece 4 superimposed on the magnetic material 5 can be viewed from above with respect to the mahjong tiles 3 from the states shown in FIGS. 4 to 7. When burying the mahjong tiles so that they are turned 90 degrees, that is, parallel to the front and rear end faces of the short side of the mahjong tiles 3, as shown in Figures 11 to 14. There is.

Next, to explain the operation, in the mahjong tiles 3 according to the present invention, the polarity of the magnetic material 5 buried inside is changed to an N polarity on one of the back side or the front side by the iron pieces 4 formed in a channel shape and polymerized. Both the and S poles are oriented, and in plan view, one pole is in the center and the other pole is located parallel to both sides of the other pole, as shown in FIGS. 4 to 7. In the case of mahjong tiles 3 in the embodiment, the suction ring 2
4, the longitudinal direction of the mahjong tile 3 is the conveyance direction of the suction ring 24, as shown on the left end side in FIGS. 8 and 9. When the state is perpendicular to the rotation direction W, the magnetic body 5 located at the center of the mahjong tile 3 and the magnet K of the attraction ring 24
In addition to the attraction effect, the magnetic poles at the ends of the left and right side walls 40, 40 of the iron piece 4 located on the left and right sides of the mahjong tiles 3 and the magnet K of the attraction ring 24 repel each other, The mahjong tiles 3 turn clockwise or counterclockwise in FIG. 9 using the attraction point between the magnetic body 5 and the magnet K as a rotational fulcrum, and as shown on the right end side in FIG.
0 and 40 are positioned parallel to both sides of the magnet K of the attraction ring 24, and the state becomes stable.
The posture of the sucked mahjong tiles 3 is automatically adjusted so that the longitudinal direction thereof is aligned with the conveyance direction of the suction ring 24. In addition, Figures 11 to 1
Regarding the mahjong tile 3 of the embodiment shown in Fig. 4, the first
As shown on the left side in FIGS. 5 and 16, when the mahjong tiles 3 are attracted with their longitudinal direction parallel to the rotational direction W of the attraction ring 24, there are Side wall 4 of iron piece 4 located
Due to the repulsion caused by one of the magnetic poles formed at the ends of the side walls 40 and 40, the ends of the side walls 40 and 40 rotate as in the case described above, and the ends of the side walls 40 and 40 are attached to the suction ring 24 as shown on the right side in FIG. The mahjong tiles 3 become stable as they are positioned on both the left and right sides of the magnet K, and the posture of the attracted mahjong tiles 3 is automatically aligned so that the longitudinal direction thereof is perpendicular to the conveyance direction of the attraction ring 24. It becomes like this.

Therefore, in the mahjong tile according to the present invention, since the magnetic body 5 and the side walls 40 of the iron pieces 4 arranged on both sides of the mahjong tile are buried in a certain direction of the mahjong tile, when the mahjong tile is attracted to the suction ring, This has the effect that the mahjong tiles themselves are rotated so that the longitudinal direction of the mahjong tiles 3 is along a predetermined direction, thereby reliably correcting the posture.
