[Prior art 1] An opening is provided in the center of the table for inserting tiles after winning, and a turntable for washing the inserted tiles and a turntable for washing the tiles after washing are provided at the bottom of the table. A tile transfer unit 1 that distributes tiles, a tile alignment unit that arranges a predetermined number of distributed tiles face down, and a tile extrusion unit that pushes up the aligned tiles onto a table, stirring and arranging the tiles and forming hinoki tiles. Margin devices that automatically perform this have been used for a long time, and many patent applications and utility model registration applications have been filed accordingly. [Problem to be solved by the invention 1] The conventional automatic margin device arranges 17 tiles face down, stacks them in two tiers, aligns them with the playing positions of the four players, and forms wall tiles. Since the process up to this point was automated, each contestant had to begin the competition by allocating the tiles in his or her hand. However, this arrangement requires each player to pick up a predetermined number of tiles from the wall layer several times in turn, which can lead to problems such as dropping tiles or breaking the wall layer. This was an impediment to rapid competition. Therefore, the automatic margin-yan device of the present invention is configured to automate the tile allocation using a simple mechanism and eliminate as much work as possible that is not directly related to the essence of the mahjong competition. [Means for Solving the Problems] The automatic margining device of the present invention has a tile insertion hole in the table for inputting tiles after winning, and an opening for raising the wall layer and hand tiles from under the table. were installed in parallel at each competition position, and the tile insertion hole was equipped with a door that could be electrically opened and closed by turning on and off a switch. On the other hand, below this table, there is a receiver that stirs and washes the tiles thrown in from the tile insertion hole, and a turntable that has a magnetic material on the upper part of the periphery so that the tiles can be controlled in a predetermined direction. A table was installed, and an endless square conveyor was installed that rotated in a rectangular plane in order to transport the tiles after washing them to the four playing positions. Then, an inflatable table is installed to separate and line up the wall layer and hand tiles at four locations corresponding to each competition position, and a lift mechanism that reciprocates by a motor is connected to this inflatable table. The tile e placing table with the wall layer and hand tiles aligned is raised so that the wall layer and hand tiles are raised from the opening onto the tabletop, and the wall layer and hand tiles are distributed to the expanded soft placing table by being conveyed by a conveyor. A mechanism is provided to carry out sorting by holding a predetermined number of tiles in a holder, moving them in parallel, and transferring them to an inflatable table.1. l1qI was designed to have a magnetic material embedded inside the back side. (Function) During the competition, when one game ends, the switch is turned on, the table is opened, and all the tiles are thrown into the tile insertion hole.The tiles are washed by the turntable at the bottom of the table, and centrifugal force The tiles are sequentially blown to the periphery of the turntable, and the magnetic material of the tiles is attracted to the magnetic material of the upper jaw, so that the tiles are sequentially sent onto the conveyor with the back side in contact with the upper jaw.Conveyor The tiles placed on the board are first placed in the first competition position and are held one after another by the mechanism, and as a first step, the 11 tiles are moved parallel from the conveyor and sent to the wall tile standby.At this time. , the wall tile standby, descends by the thickness of the tiles.As the second step, the next 11 tiles are held in the sorted tj[, and are placed on top of the 11 tiles lined up on the wall tile standby. The tiles are moved in parallel from the conveyor and placed on the conveyor.As a third step, the 12 tiles on the conveyor are held by a mechanism and moved in parallel to the hand tile standby.At the first playing position, the first, When the second and third steps are completed, the tiles are sent to the second playing position by a conveyor.
Similar to the first competition position, the distribution goes through the first, second, and third steps by the mechanism, and the 22 wall tiles stacked in two layers are placed on the wall tile standby, and the hand tiles are placed on the hand tile standby. Twelve tiles are laid out. Next, the above operation is repeated at the third competition position and finally the fourth competition position, and when the wall layer and hand tiles are aligned at the four competition positions, the fourth step is to wait for the wall tiles. The wall layer on the table is sorted by a mechanism that presses them and placed on the inflatable table for wall tiles, and in the fifth step, the hand tiles on the hand tile standby table are sorted by a mechanism that is pressed and placed on the wall tiles. Place it on the inflatable table. When the wall layer and hand tiles are transferred to the tile e placing table, the tile i placing table is moved upward by the lift mechanism, and the two stacked wall layer and 12 hand tiles are arranged in their respective competition positions on the table, and the tiles are placed. The hole door will be closed and the preparation work for the competition will be completed.

The mechanism for distributing the wall tiles and hand tiles provided at four locations is a gear transmission mechanism so that it can be driven by a single motor 35. FIG. 6 shows this gear transmission mechanism. Next, the operation will be explained based on the above embodiment. When one game of competition is completed and necessary work such as score calculation is completed, one of the competitors presses the switch 61 on the table. When this switch 61 is turned on, the door 6 of the top board 2 opens, and each player drops all the tiles on the top board 2 through the expansion hole 5 into the inside of the table 1. All the tiles are received by the turntable 16, and the tiles are washed by rotating the turntable 16 when the switch 61 is turned on. The washed tiles are sequentially blown toward the outer periphery by the centrifugal force caused by the rotation of the turntable 16, and the back side of the tiles is attracted by the attractive force of the magnetic material provided in the upper jaw 17 of the turntable 16. It is sent to the guide route 20. Guide route 20
The tiles that pass through the conveyor 18 advance in the length direction of the tiles.
placed on top. At this time, the length direction of the tiles is conveyor 18.
perpendicular to the direction of travel. The conveyor 18 is rotating when the switch 61 is turned on, and the tiles are conveyed one after another by the conveyor 18, first at the first playing position 62.
Head to. At the first competition position 62, the holder 4 of the distribution n structure 39
1 has its stopper 44 perpendicular to the conveyor 18 to prevent the tiles from advancing, and when the detector detects that 12 tiles are held in the holder 41, the sorting is done by the mechanism 390. The braking unit 42 is activated. That is, the main shaft 46
is rotated by the motor in the clockwise direction in FIG. 4, and the second belt 57 is rotated clockwise by the belt transmission mechanism. The holder 41, which is integrally connected to the second belt 57, slides to the right in the figure together with the second belt 57, and the 12 tiles are placed on the wall tile standby stand 21. At this time, only one tile at the tip is placed on the plate piece 63 separated from the wall tile stand 21. The solenoid turns off and the wall tile standby stand 21 on which the 11 tiles are placed descends, and the 11 tiles leave the holder 41. On the other hand, the rotary plate 49 attached to the main shaft 46 of the brake part 42 rotates as the main shaft 46 rotates, and if it detects that the bulge 48 has reached the position of the sensor 59. Rotating the main shaft 4θ in the opposite direction, that is, counterclockwise,
If it is detected that the bulging portion 48 has returned to the position of the sensor 58, the rotation of the main shaft 46 is stopped. As a result, the holder 41 makes one reciprocation on the wall tile stand 21 and the conveyor 18, and out of the 12 tiles, only one tile makes this reciprocation together with the holder 41, and then moves back and forth on the conveyor 18. taken back to the top. Next, the tiles are conveyed by the conveyor 18, and when the 12 tiles are held in the holder 41, the holder 41 is again slid in the direction of the wall tile standby stand 21 by the braking unit 42, and the 11 Place one tile on top of the previous 11 tiles. The remaining tile is placed on the board 63 again,
As the holder 41 returns, it is returned onto the conveyor 18. Mihara 12 is placed inside the holder 41 which has made three reciprocating movements.
When one tile is held, the main shaft 46 rotates counterclockwise for the second time, rotates the second belt 5T counterclockwise, slides the holder 41 onto the hand tile standby stand 26, and 12 Place the tiles on the hand tile standby stand 26. At this time, the rotary plate 49 of the brake part 42 also rotates counterclockwise, and is reversed until the bulge part 48 returns to the position of the sensor 58. When the holder 41 returns to the conveyor 18, the stopper 44 is activated by the solenoid 43.
The tiles are vibrated by the ceiling and prevented from progressing on the conveyor 18. Therefore, the tiles are sent to the second competition position 66, and like the first competition position 62, the wall tiles and hand tiles are respectively placed on standby tables. The same applies to the third competition position 67 and the fourth competition position 68. Next, when the second switch 69 of the table 1 is turned on, the door 6 closes the expansion inlet hole 5 and the lower part of the upper root 2 is opened. 8, 9.10.11.12.13.14 Due to the downward movement of the expansion table 30, tiles were placed on the wall tile stand 21 and the hand tile stand 26 by means of the screws tIjI4, etc. It will rise to its previous position. Therefore, the distribution is machine 41'1
