Description

[Detailed description of the invention] The present invention relates to a tile supply device for an automatic mahjong table.

More specifically, the mahjong tiles that have been played are received into a drum-shaped tile-washing hopper installed below the mahjong table, and placed on an inclined and rotating turntable that serves as the bottom plate of the tile-washing hopper. A tile arrangement in which the tiles are stirred and washed, sent up to the upper end side of the slope by the peripheral edge of the turntable, and supplied to a carry-out conveyor while being controlled in a constant posture, and the Mahjong tiles are arranged in a tiled state by the carry-out conveyor. This invention relates to an improvement in a tile feeding device for feeding washed mahjong tiles from the periphery of a turntable to a carry-out conveyor while arranging them in a constant posture in an automatic mahjong table that feeds the tiles to a turntable.

As shown in FIGS. 1 and 2, the tile supply device in the automatic mahjong table described above is embedded inside the mahjong tiles P inside the peripheral wall 10 of the tile washing hopper L formed in the shape of a drum. Magnets 2 are arranged with polarities that act on a certain magnet and attract the back side of the mahjong tile P. The stirred and washed mahjong tiles P... are swung out onto the peripheral edge 30 of the turntable 3, and the mahjong tiles P...
When the mahjong tiles P are carried to the ascending side of the slope by The mahjong tiles are conveyed in this state and are dropped into the tile washing hopper 1 from the peripheral edge 30 of the turntable 3 into the tile washing hopper 1 by the thickness sorting member 4 disposed above the peripheral edge 30 of the turntable 3. While controlling the tile washing hopper 1, the tile washing hopper 1 is delivered to the upper surface of a delivery conveyor 5 disposed on the side.

By the way, in this conventional means, the mahjong tiles P conveyed by the peripheral portion 30 of the turntable 3 are moved to the tile washing hopper 1 by magnets 2 embedded inside the peripheral wall 10 of the tile washing hopper 1. Since the circumferential wall 710 is moved toward the inner wall surface 10a side so as to be in pressure contact with the inner wall surface 10a, and is moved while being in sliding contact with the inner wall surface 10a of the circumferential wall 710, the attracting force of the magnet 2 causes the circumferential wall lO inner wall surface 10 of
Since the mahjong tiles P are attracted to a, the peripheral portion 30 of the turntable 3 causes the mahjong tiles P.
There is a problem in that the transfer action of . . . becomes uncertain, and the time required to send out all the mahjong tiles P from the tile washing hopper 1 to the tile alignment section becomes longer.

Moreover, the mahjong tiles P that have been adsorbed to the inner wall surface 10a of the peripheral wall 10 of the tile washing hopper l will be turned one after another if a large amount of mahjong tiles P... remain in the tile washing hopper 1.

However, when the number of mahjong tiles P in the tile washing hopper 1 decreases, some mahjong tiles P stick to the inner wall surface 10a of the peripheral wall 1O and do not move. When there is no mahjong tile P to push it out, or one or two poles (few mahjong tiles P)
. . . When pushed, the tiles become stuck, which causes the tiles to rise from the peripheral edge 30 of the turntable 3 and remain stuck for a long time, causing a problem in which the tile alignment operation is not completed. In the conventional means, a mahjong tile P with the front side facing upward is generated among the mahjong tiles P brought together by a magnet 2 so as to come into pressure contact with the inner wall surface 10a of the peripheral wall 10 of the tile washing hopper l. In this case, even the thickness sorting member 4 cannot remove the mahjong tiles P towards the center of the tile washing hopper 1. The peripheral part 3
