Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper device for forming a wall tile of an automatic mahjong table, which is used to form a tile that is agitated on a turntable into a two-tiered wall tile on a stand.

[Prior art]

The operation of mixing tiles, the operation of turning the mixed tiles down, the operation of aligning a predetermined number (usually 34) of tiles to form a two-tiered castle wall tile, and the operation of lifting the castle wall tabletop. An automatic mahjong table that can automatically perform the above is well known in the past, and the castle wall tiles are usually formed on a waiting stand that is vertically movable, and the tiles that are sent onto this waiting stand are tiles. The required number of items is controlled by a computer command. By the way, in order to form a two-tiered castle wall tile orderly,
A stop plate is provided at a predetermined position on the waiting table so that it can be fixed or can be freely moved in and out, and the top tiles sent into the waiting table (the tiles sent in first to form the first-row castle wall tiles) A method of restricting the stop position of No. 1 by a stop plate is adopted (see Japanese Utility Model Laid-Open No. 60-119486).

[Problems to be Solved by the Invention]

When the stop position of the leading tiles sent on the stand is regulated by the stop plate by the above-mentioned conventional method, the size of the tiles (width of the tiles in the feeding direction) is slightly different,
Due to the fact that the leading tile is pushed by the succeeding tile to proceed, the castle wall tile formed on the waiting stand is formed at the front part slightly separated from the stop plate, or the first tile hits the stop plate and the last tile. However, there is a problem that it slightly protrudes from the stand. That is, when the size of the tiles is small and the length of the wall tiles is short, a large number of gaps are generated between the adjacent tiles due to the impact of the succeeding tiles when pushing the preceding tiles. Become. Therefore, when the operation of sending the tiles onto the lower (first) castle wall tile where there are many gaps to form a two-tiered castle wall tile is performed, the tiles in the lower castle wall tiles are tiled. There is a phenomenon that the tiles in the upper row are laid sideways in a sideways state. Also, if the tiles are large and the wall tiles are long, the leading tiles will hit the stop plate and stop, so the specified number of tiles cannot be sent correctly onto the stand, and Tail tiles often ran out from the top of the stand, but there was a need for a solution.

[Means for solving problems]

The present invention has been made in view of the above points, and an object thereof is to slightly move the stop position of the leading tile for forming the first-row castle wall tile that has been sent onto the waiting stand to the forward direction. Using a stopper that can be moved, place this stopper under the action of a return spring so that it can be retracted by pressing the top tile, and retract the stopper according to the length of the lower castle wall tile formed on the standby table. The object of the present invention is to provide a stopper device for forming a castle wall of an automatic mahjong table which is improved so that a two-tiered castle wall tile can be formed in an orderly manner with the tiles sent in close contact with each other. Therefore, the above-mentioned object of the present invention is to install a waiting stand on which tiles are aligned to form a two-tiered castle wall tile, and to be installed facing the leading end side of the waiting stand, and to be fed onto the waiting stand. A stopper that is pushed back by the leading tile of the tile for forming the first-row castle wall, a stopper that is detachable from the stopper and that prevents advance of the stopper when engaged, and this stopper. And a release member for releasing the engagement between the blocking piece and the stopper, the standby table is installed so as to be movable up and down, the stopper is slidable under the action of a return spring, and The blocking pieces are each rotatably provided under the action of a return spring, while the release body is formed with a two-tiered castle wall tile on the waiting stand, and the waiting stand is raised to a position higher than the stopper. Automatic hemp configured to be activated when It is achieved by ramparts tiles forming device for stopping table.

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings. Each stand 1 is provided so as to be able to move up and down at a position corresponding to each side of an apparent square, and the stand 1 is supported by a support rod 2 and is constructed so as to be able to move up and down by a link mechanism not shown. ing. Inside each waiting stand 1, the waiting stand 1
An elevator platform 3 for lifting the two-tiered castle wall tiles formed above to a table is installed so that it can be raised and lowered.
Adjacent ones are connected via an elevating arm 5 that ascends and descends along a guide shaft 4, and each elevating table 3 is designed to elevate simultaneously. A stopper 7 supported on a support frame 6 so as to face the tip 1 is slidably provided on the tip 1a side of the waiting stand 1, and the stopper 7 is locked between the stopper 7 and the support frame 6. It is placed under the action of a return spring 8. The stopper 7 is provided with a guide long hole 9 along the length direction, and a pair of support pins 11 projecting from the support frame 6 are inserted into the guide long hole 9 to guide the forward and backward movement of the stopper 7. It is designed to do. A ratchet (following tooth) 12 is engraved on the lower side of the stopper 7, and a tip of a blocking piece 14 placed under the action of a return spring 13 hooked between the ratchet 12 and the support frame 6.
14a is disengageable, and the blocking piece 14 is rotatably attached to the support frame 6 by a shaft 15. Further, the blocking piece 14 can be pressed by a release member 16 provided on the support frame 6 so as to be able to move up and down,
In the case shown, the lower end 16 a of the release body 16 is supported on the blocking piece 14, while the upper end of the release body 16 is located directly below the lifting arm 5. The release body 16 is provided with a guide elongated hole 17, and a pair of guide pins 18 projecting from the support frame 6 are inserted into the guide elongated hole 17 to guide the lifting and lowering operation of the release body 16. The stopper 7 has a tip 7a side projecting freely onto the stand 1. The stopper 7 is set at a height such that the top tile P _{1 of the} tile P sent to the stand 1 can come into contact with the tip 7a. On the side of the tip portion 1a of the stand 1 is provided a notch 19 formed by cutting from the front end face thereof.
By 19, the trouble that the stand 1 hits the stopper 7 during the lifting operation is eliminated. A roller 21 is rotatably attached to the upper end of the releasing body 16. Next, the operation of the above embodiment will be described. Place the stopper 7 on the stand 1 for a specified length (1 to 1.
About 5 pieces are projected and when the tiles P are sequentially fed onto the stand 1 as shown in FIG. 1 and FIG. 2, the leading tile P ₁ is pushed by the succeeding tiles P to move forward and the tip of the stopper 7 is pushed. The stopper 7 is retracted by hitting 7a. The backward movement of the stopper 7 is stopped when a predetermined number of tiles P have been sent onto the stand 1, and the stopper 7 is held at the backward position by the blocking piece 14. Therefore, even if the length of the first-stage castle wall tile formed on the waiting stand 1 varies slightly depending on the size of the tile P, the stopper 7 projecting on the waiting stand 1 initially causes the _first tile P ₁ The stop position is automatically adjusted, and it is possible to solve the problem that a gap is created between the aligned tiles. Next, as with the conventional automatic mahjong table, when the first-row castle wall is formed, the waiting stand 1 descends, and the tile feeding for forming the second-stage castle wall tile is started on the castle wall tile. . 1
When a predetermined number of tiles (the same number as the first-row castle wall tiles) are sent onto the second-tier castle wall tile and the second-tier castle wall tile is formed on the waiting stand 1, the waiting stand 1 rises, The lift 3 descends,
The operation of transferring the two-tiered castle wall tiles from the stand 1 to the lift 3 starts. In this series of operations, the release body 16 is integrated with the lifting table 3 when the lifting table 3 descends.
The stopper piece 14 is pushed by and is rotated to remove it from the stopper 7 (see FIG. 3), and the stopper 7 is advanced by the return spring 8 and returned to the original protruding position. In this case, the raising operation of the standby table 1 and the lowering operation of the elevating table 3 are performed in synchronization with each other, and the release member 16 is controlled to be pressed immediately after the standby table 1 is separated from the stopper 7 above. In the above description, the release body 16 is operated by the lowering operation of the elevating table 3, but this can be implemented so as to be operated by the elevating operation of the standby table 1. Further, the engagement / disengagement means of the stopper 7 and the blocking piece 14 may use a frictional force that presses the tip 14a of the blocking piece 14 against the stopper 7, and in the case of utilizing this frictional force, the stopper 7 is stopped steplessly. be able to.

【The invention's effect】

The present invention is as described above, and the tiles forming the first-row castle wall tiles that have been sent onto the standby table have the stoppers with their leading ends stopped under the action of the return spring. Since it is automatically adjusted by the operation, even if the length of the castle wall tiles formed on the standby table fluctuates, it is possible to align a predetermined number of tiles all in close contact and align them It is possible to completely prevent the occurrence of troubles due to the gaps generated between the two, and it is possible to form a two-tiered wall tile in an orderly manner.
