Each is floated and supplied.

[0004]

However, in the above-mentioned conventional tile transfer device, since the drive mechanism for the turntable and the drive mechanism for each transfer conveyor are separately provided, the automatic mahjong machine is large in size. There was a problem of becoming heavy.

An object of the present invention is to reduce the size and weight of an automatic mah-jongg machine by using a common drive mechanism for the turntable and the conveyor in the tile-carrying device of the automatic mah-jongg machine.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention mixes a set of tiles, which are inserted from a tile insertion opening opened on a top plate of a table body, by rotating a turntable. An automatic mah-jongg machine carrying four sets of conveyors and carrying them to the tile stacking machines at each competition corner. The turntable is rotatably supported in a horizontal state and is placed under the turntable. A ring-shaped floating gear is concentrically arranged and rotatably supported, and four bevel teeth provided on the circumference of the floating gear are arranged under the circumference of the floating gear at intervals of about 90 degrees. The bevel gears are meshed with each other, and the bevel gears are respectively connected to the drive pulleys of the four sets of conveyors. The bevel gears, the second tooth portion provided on the circumference of the idle gear, and the circumference of the lower surface of the turntable are connected to each other. Receiving gear integrally provided The contact meshed via an intermediate gear, is the concatenation of one of the drive mechanism to the gear transmission system.

[0007]

According to the above means, the turntable is rotatably supported in the horizontal state, and the idle gear is rotatably supported in the lower portion of the turntable in a state of being concentric with the turntable.

The idle gear is provided with a bevel tooth portion and a second tooth portion on its circumference, and the bevel tooth portion is provided with four bevel teeth arranged under the circumference of the idle gear at intervals of about 90 degrees. The bevel gears mesh with the gears, and each bevel gear is connected to the drive pulleys of the four sets of conveyors to transmit the drive. In addition, the second of the idle gear
The tooth portion meshes with a receiving gear that is integrated with the turntable via an intermediate gear to transmit the driving force.

A single drive mechanism is connected to the above-mentioned gear transmission system, and the driving force of this drive mechanism is applied to the gear transmission system to rotate the turntable and simultaneously drive four sets of conveyors.

[0010]

Since the present invention is constructed as described above, it is possible to drive the turntable and four sets of conveyors by one driving mechanism. Therefore, as compared with a conventional tile transfer device in which the turntable and the transfer conveyor are separately provided with a drive mechanism, the structure of the device can be simplified because the number of drive mechanisms is one. The automatic mahjong machine itself can be made smaller and lighter.

FIG. 1 shows the inside of the automatic mahjong machine. This automatic mahjong machine has a square table main body a1 inside which a turntable 1 and a tile transfer device a2 comprising four sets of tile transfer conveyors,
And four sets of tile stacking devices a3 are built in, and the upper surface of the table main body a1 is normally covered with a top plate a4.

In the center of the table main body a1, the tile transfer device a2
This turntable 1 is provided with
Four sets of transport conveyors 2 are arranged so as to surround the four surfaces around. Further, four sets of tile stacking devices a3 for supplying tiles to each competition corner are arranged outside each transport conveyor.

The turntable 1 of the tile transfer device a2 mixes the tiles inserted from the tile insertion door a5 at the center of the top plate a4 each time the game is finished, and sends them out toward the outer periphery.
The tiles ejected to the outer periphery by the turntable 1 ride on the starting ends of the respective conveyors 2 and the respective tile stacking devices a3.
Be transported to.

The tiles conveyed by the conveyor 2 to the receiving port of each tile stacking device a3 are sent out one by one by the feeding mechanism 51 of the device a3 in the form of 90-degree direction change, and one line on the stacking plate 54. 17 pieces can be stacked in two stages. Then, when the next game is started, the push-out mechanism 53 reloads the lifter plate 54 as it is, and the lifter plate 54 moves up to be supplied from the tile floating opening 55 of the top plate a4 to each competition corner. It

The turntable 1 of the tile transfer device a2 arranged in the center of the table main body a1 is a dish-shaped disc formed in a polygonal pyramid shape on the upper surface as shown in FIGS. A step is provided along the side. In addition, the pillar 1a is formed on the lower surface of the turntable 1, and the lower end of the pillar is supported from below by the thrust bearing 11 fixed to the bottom surface of the table body a1, so that the turntable 1 is in a horizontal state. It is supported rotatably while maintaining.

A floating gear 3 is rotatably provided on the outer periphery of the column 1a of the turntable 1 via a bearing 12. As shown in FIG. 4, the floating gear 3 is provided with a bevel tooth portion 3a formed on the lower surface of the circumference and a second tooth portion 3b formed on the outer circumference of the circumference. It meshes with four bevel gears 4 which are arranged under the circumference of the floating gear 3 at intervals of 90 degrees.

Each bevel gear 4 is attached and fixed to one end of a shaft 13 which is rotatably supported along a line extending from the center of the turntable 1 toward the outer circumference.
Drive pulley for the conveyor 2 fixed to the other end of 13
It is integrally connected to 2a.

Each transfer conveyor 2 is a drive pulley as described above.
The conveyor belt 2c is installed between 2a and the folding pulley 2a attached to and supported by the conveyor guide plate 2b, and the conveyor belt 2c is configured to be guided along the conveyor guide plate 2b by the guide roller 2e. .
Further, the conveying path constituted by the conveyor belt 2c is inclined so as to rise toward the feeding mechanism 51 which is the receiving end of the tile stacking device a3 at the end.

On the other hand, the second tooth portion 3b of the floating gear 3 is a table body a.
It meshes with a receiving gear 6 provided on the lower surface of the turntable 1 via an intermediate gear train 5 installed on the bottom surface of the turntable 1. The receiving gear 6 is configured by providing a tooth portion on the inner peripheral surface of the ring-shaped member, and is attached and fixed in a state of being coaxial with the turntable 1.

As a result, the receiving gear 6 for driving the turntable 1 and the bevel gear 4 connected to the drive pulley 2a of each conveyor 2 are interlocked via the idle gear 3. As described above, the four bevel gears 4 for driving the conveyors 2 and the intermediate gear train 5 for driving the turntable 1 are connected to each other through the ring-shaped floating gears 3 to form a partial mesh It is possible to prevent a problem in which a large load is applied only to the part.
