Description

[Detailed Description of the Invention] The present invention is such that when tiles are thrown into the insertion hole provided in the center of the mahjong table after winning, the tiles are automatically washed, and the tiles are lined up in front of each player so that the face of the tiles is on the player's side. Automatic tile washing and stacking at a mahjong table in which a fixed number of hand tiles in a vertical state facing the direction of the hand and a wall tile row in two stacks with the faces facing down are automatically supplied at a constant rate. This invention relates to a tile-laying method and its device.

Conventional automatic mahjong tables generally have a system in which only the tile washing is performed automatically, or a system in which after this tile washing is performed, the process up to the wall tiles stacked in two stacks is automatically performed. For example, Japanese Patent Application Publication No. 51-82132, Utility Model Application Publication No. 49-
No. 10680 can be mentioned. Therefore, even in automatic mahjong tables, it is necessary for each player to deal out wall tiles for each competition to use as hand tiles, so there is a drawback that it takes a lot of effort and a little time to start the competition.

In view of this, the present invention aims to completely automatically perform the process from washing tiles after a win to forming wall tiles and distributing tiles.

The present invention will be explained below based on examples.

In the figure, 1 is a mahjong table with the required shape, with a winning hole 1a in the center for inserting all the tiles after winning, and a mahjong table 1a on the four sides of the table facing each player. A hand tile rising hole 1b is placed at the position where the 13 hand tiles are arranged, and a wall tile rising hole 1c is placed at the position where the wall tiles are arranged.
Make two rows and drill holes in each. This winning tile insertion hole 1a is not only circular as shown in the figure, but also has a rectangular or other shape, and is provided with an elevator platform 2 that fits into the hole 1a and is movable up and down. In addition, the hand tile lifting hole 1b is a long hole with the same area as the 13 tiles standing in a row horizontally with the letters or pictures facing the player. be equipped with
The wall tile ascending hole 1c is a long hole with approximately the same shape as the hand tile ascending hole, but in this case, the wall tiles are arranged horizontally in a row with each tile stacked in two layers with the back side facing upward. The size shall be the same as the area of . This wall tile rising hole is the same size on the opposite side, but the upper and lower sides are different. This is because the wall tiles are arranged in two rows of 10 and two rows of 11. A wall tile lifting platform 4 is provided in each of the wall tile lifting holes so as to be able to rise and fall freely.

The above-mentioned winning tile insertion hole 1a is provided with an elevating platform 2 which opens only when a winning tile is inserted, which can be raised and lowered by a solenoid SOL and a link mechanism L, and at a lower position thereof is a turntable which is rotationally driven by a motor or the like M. A table 5 is provided, and a magnet 6 is placed at the bottom of the turntable 5.
is provided, and the magnetic force of the magnet 6 is applied to the tiles on the table in which the magnets or iron pieces are embedded, so that the tiles are aligned so that the font face is facing down, and the tiles can be washed at the same time. The magnets are arranged so as to face each other over the entire lower surface of the turntable, or are arranged only on the outer circumferential side of the turntable as shown in the figure. In addition, guides 7 are provided on the outer circumference of the upper part of the turntable 5 to prevent the tiles on the turntable from flying out of the table due to the centrifugal force of the rotation of the table. A door 8 is provided to open and close the four tile sending ports 7a using a solenoid, and a protruding rod 7b is protruded above the turntable to ensure that the tiles are washed and to align the tiles after washing. The protruding rod 7b is made to protrude above the table surface from a part of the guide 7, so that the tiles on the table surface that collide with the protruding rod 7b change their direction to the same direction.

The turntable is rotated to such an extent that a centrifugal force is applied so that each tile that falls onto the turntable, is washed by the rotation of the table and the action of the magnet, and is then sent out from the tile outlet on the outer periphery of the table. The turntable is driven by providing speed, and to aid this action, the turntable is sometimes shaped so that the center rises above the turntable surface. The tile delivery ports provided in the guide provided on the outer periphery of the turntable are provided in a tangential direction to the turntable outer periphery to facilitate the delivery of tiles, and each tile delivery port is equipped with a solenoid.
A door 8 that opens and closes at SOL is provided, and a chute 9 and a belt conveyor 10 are provided outside the door for delivering tiles arranged in one direction in a single line. Immediately after the tiles that have come out of this tile delivery port pass the tip of the door, the counter 11 that counts the number of tiles sent out is operated by the shooter 9.
This counting device 11 is provided on the side of the starting end of the counter, and this counting device 11 is synchronized with a solenoid SOL. After the tile washing is completed, when a constant number of tiles stored in advance in the counting device is sent out from the opened door, this counting device A closing command is given to the solenoid to close the door and prevent any more tiles from being sent out.The measured number is 33 or 35, and this is the number of tiles that are sent out in front of each player. be approximately equal. A counting device 12 is further provided at the end of the belt conveyor 10, and the number of tiles for wall tiles and hand tiles is counted to be divided into set numbers. belt conveyor 10
A chute 13 is connected to the starting end of the chute 13 through a door 14 that can be opened and closed by a solenoid.
a to a wall tile stacking device 15, and a belt conveyor 16 is connected to the other chute end 13b. This belt conveyor 16 is equipped with a magnetic roller, and the belt conveyor 1 is
6. The tiles being conveyed on the top are further turned over and arranged so that the surface on which the letters or figures are drawn is the top surface. The magnetic rollers may be used as rollers at both ends or one side of the belt conveyor, or one or more magnet rollers may be provided between the rollers at both ends. A chute 17 is connected to the end of this belt conveyor 16 to guide the counted 13 tiles to a hand tile arrangement device 18. The above wall tile stacking device 15 is 10 or 11
One end of the gutter-like main body having a length that allows the tiles to be lined up in a line is connected to the end 13a of the chute, and this end is equipped with an extrusion device 19 and a detection device 20 for detecting that the tiles are stacked in two stages. Seshimeko's devices 19 and 2
0 is synchronized to drive, that is, when it is detected that tiles are stacked in two stages in the main body, the extrusion device is activated and pushes out the stacked tiles by one pitch, with the width of one tile being one pitch. In this way, the required number sequences are sequentially arranged in a horizontal line. An extrusion device 21 and a detection device 22 are also provided at the end of the hand tile arrangement device to perform the same operation, i.e., when a tile is supplied into the device 18 in an upright state, the detection device 22 detects this and then the extrusion device 21 is activated to push out only one tile, and the same action is repeated one after another, lining up 13 tiles in a row to form a hand.

The tiles are washed as described above, and the required number of hand tiles and wall tiles are arranged. This is arranged on the same plane as the lowering elevator tables 3 and 4, and in a horizontally adjacent position.

Then, each of the tiles is simultaneously pushed out to the lifting tables 3 and 4 through the extrusion device 23,
The top surface of the lifting platform is raised until the top surface of the table is flush with the top surface of the table, and then stopped. This elevation is performed by an elevating device 24 provided at the lower part of the elevating table.

It should be noted that the tile delivery outlet door provided on the outer periphery of the turntable is not opened until the tiles are completely washed, and this is set in advance in the program.

According to the present invention, the tiles after the winning are placed into the open slot, and the tiles are washed, stacked, and hand tiles and wall tiles are divided into constant numbers and the tiles are completely dealt. Since the tiles are arranged in two rows and protrude to the top of the table, the contestant does not have to deal any tiles at all, and the match can begin immediately by copying one tile by himself, which shortens the playing time and completely eliminates fraud when placing tiles on the wall. It has the advantage of preventing
