Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an improvement of a tile supply device in an automatic mahjong table.

[Conventional technology]

As shown in FIG. 6, as a conventional tile supply device for this type of automatic mahjong table, the center of the upper surface of a rotary table 31 rotates with an oblique axis of rotation by a support shaft 20 with an oblique center line. A ring 6 that loosely fits on the support shaft 20 and rotates freely with respect to the rotary table 31 is provided at the portion, and the ring 6
The proximal end of the coil spring 7 is locked, and the coil spring 7 is
The free end side of the mahjong tiles P are extended along the upper surface of the rotary table 31 in the radial direction thereof, and the mahjong tiles P fall onto the upper surface of the rotary table 31 and rotate together with the rotary table 31. There is a means for guiding the... in the outer circumferential direction by using the coil spring 7 which is stopped on the upper surface of the rotating rotary table 31 so as to dam up the turbulence in the rotational direction.

[Problem that the idea aims to solve]

However, in this method, the coil spring 7 is easily stretched, and therefore, the rotating mahjong tiles P pass through the lower surface side or the upper surface side of the coil spring 7 in many cases, and the upper surface of the rotary table 31 The main problem is that the original function of guiding the mahjong tiles P... toward the outer circumference of the rotary table 31 is no longer possible, and that the free end side of the coil spring 7 is deposited on the upper surface of the table 31 and together with the rotary table 31. The mahjong tile P... is pushed by the rotating mahjong tile P, and as shown by the chain line in Fig. 7, the mahjong tile P...
1, the mahjong tiles P are moved in a state where they are wrapped around the spindle 20, and the mahjong tiles P are jammed in an aligned state between the inner wall surface of the tile washing hopper 30 and the spindle 20. The coil spring 7 rotates together with the mahjong tile P... and moves the mahjong tile P... to the rotating table 31.
There is a problem in that the ability to guide the material to the outer circumference side is lost. The present invention was devised in order to solve these problems in the prior art, and it is possible to reliably guide the mahjong tiles on the rotary table toward the outer periphery of the rotary table. An object of the present invention is to provide a tile supply device for a new automatic mahjong table that can shorten the time required to set a tile to a built state.

[Means to solve the problem]

As a means to achieve this objective, the present invention provides a method for installing a rotary table above a rotary table which is pivoted to rotate with an oblique axis of rotation at the bottom of a tile washing hopper below a mahjong table. A rod-shaped elastic body is arranged in a vertical position near the center of rotation, with its longitudinal direction facing up and down, and the upper end of the rod-shaped elastic body is supported by a bracket fixed to the machine frame. The lower end side of the elastic body is made to face the upper surface of the rotary table as a free end, and at the free end is a base of a guide plate extending radially along the upper surface of the rotary table and toward the inclined downward side of the rotary table. This invention proposes a tile supply device for an automatic mahjong table, characterized in that the ends are attached and supported.

[Effect of the idea]

The tile supply device in the automatic mahjong table according to the present invention configured as described above has the slot 12 of the mahjong table 1.
The mahjong tile P dropped from... is washed by the tile hopper 3
A rotary table 31 supported to rotate with an oblique axis of rotation Z at the bottom of the rotary table 31 receives the rotary table 31, and the rotation of the rotary table 31 rotates the rotary table 31 so that it is in a prone position while conveying the peripheral part of the rotary table 31. It is then sent to the section 31a. At this time, the winning mahjong tiles P that accumulate on the top surface of the rotary table 31 and rotate together with the rotary table 31 are distributed along the top surface of the rotary table 31 from the center to the outer periphery. A guide plate 42 arranged to cross in the radial direction toward the downward slope side
By coming into contact with the guide plate 42, the guide plate 42 is guided to the conveyance section 31a on the outer peripheral edge of the rotary table 31, and the guide plate 42 is positioned close to the rotation center of the rotary table 31, with the longitudinal direction thereof being the vertical direction. The guide plate 42 is attached to the free end of the rod-shaped elastic body 4, which is arranged in a vertical position and whose upper end is fixedly supported on the machine frame 2.
Since it is supported by attaching the base end of the mahjong tiles P, the position along the upper surface of the rotary table 31 is maintained even when receiving resistance from the mahjong tiles P being guided. That is, when the guide plate 42 is pushed in the rotational direction of the rotary table 31 due to the resistance of the mahjong tiles P that it guides, the rod-shaped elastic body 4 in the vertical posture supporting the guide plate 42 moves due to its elasticity. By twisting and bending, it comes to maintain a posture along the upper surface of the rotary table 31 and traversing the upper surface in the radial direction. Therefore, the mahjong tiles P on the rotary table 31 are guided by the guide plate 42 arranged along the radial direction on the upper surface of the rotary table 31.
The operation of guiding the mahjong tiles P toward the conveyance section 31a at the outer peripheral edge of the mahjong tiles P is now performed properly and efficiently, and the efficiency of supplying the mahjong tiles P to the alignment section b is significantly improved, which speeds up the completion of setting. You will be able to improve your skills.
