Description

[Detailed description of the invention] (Field of industrial application) This invention corrects the direction of tiles that fall vertically from the stirring device of a fully automatic mahjong table by placing them inside the drop opening, and then vertically placing them on the tile holder. When the placed tiles are sent forward by the tile feeder, slide down the sloped guide part formed at the front of the tile holder, and are stacked in two tiers on the tile alignment table, the tile holder This invention relates to a tile feeding device that slides down an inclined guide portion formed at the front of the table and stacks tiles in two stages on a tile arrangement table.

Conventional tile dispensing devices are provided with various mechanisms, but one example, as shown in Fig. 1, is a tile holder with a curved and sloping front part. Since the structure has a guide plate slightly formed on both sides of the section, the tiles sent out by the tile feeding table slide down on the guide section, and when arranged in two stacks on the tile alignment table, the tiles are There was a risk of problems such as lateral displacement or vertical alignment.

As a result of investigating the cause from various angles, we found that the lateral shift is caused by the fact that the guide plate only protrudes slightly to the side of the guide part of the tile holder, so when the tiles are arranged on the tile alignment stand, It turned out that he was not fulfilling his role as a guide.

It has also been found that the cause of the vertical drop is a slight difference in the feeding speed of the tile feeder, that is, if the tile is fed out strongly, the tile will be thrown out.

The purpose of the present invention is to eliminate the troubles caused by the above-mentioned causes, and to provide a tile feeding device for a fully automatic mahjong table that prevents tiles from falling vertically and from shifting laterally. .

The drawings will be described in detail below.

This is a rotating plate that is attached to the chain 10 and serves to rotate the V-shaped lever 7 as the chain 10 rotates.

The operation of the present invention having the above configuration will be explained next.

When one game is completed, the tiles are put into the stirring device, and the tiles stirred on the rotary board B pass through the tile drop opening 1 and are placed in the tile feeding table 2, where they are placed in a vertical tile holder. 3, a sensor (not shown) provided on the tile feeding table 2 senses the information and transmits the information to a separately provided computer.

Upon receiving the transmission, the computer issues a command to the drive device, and the drive device starts to rotate the chain 10 with sprockets S, S ₁ , S ₂ and S ₃ in the direction of the arrow as shown in Fig. 4. Then, the V-shaped lever 7 is rotated by a rotating plate 13 attached to the chain 10.

The tile feeding stand 2 moves forward together with the tile holder 3 by the arm lever 8 that interlocks with the V-shaped lever 7, but as shown in FIGS. The stopped stopper 11 is stopped by a stopper receiver 14 provided at the front of the unit main body C, and the tile feeding table 2 moves by a predetermined width, and the tiles slide down on the guide part 4.

That is, due to the difference in movement between the tile holder 3 and the tile feeder 2, the tiles slide down on the guide section 4 and are aligned on the tile alignment table D, but the lateral deviation of the tiles during alignment is due to the tile feeder. This is prevented by guide plates 2a protruding from both front sides of the stand 2.

Furthermore, when the tiles slide down onto the guide section 4, there is a risk that the tiles may fall in a vertical shape, so as shown in FIG. 4a so that the tip of the auxiliary guide 5 protrudes outside of the pin 5'.
By attaching it so that it can rotate freely around the axis, it is possible to prevent it from falling vertically.

That is, by making the front bottom of the tile that slides down the curved inclined surface of the guide part 4 in a vertical posture lightly contact the tip of the auxiliary guide 5, the tile will surely fall forward. This is how it was done.

In addition, the tiles that slide down on the guide section 4 are handled by the tile feeding table 2.
Since the tiles are placed between the guide plates 2a protruding from both sides of the front part of the tile feeding table 2 until they are sent out by the tile holder and stacked in two tiers on the tile alignment table D, there is no lateral displacement of the tiles and the tiles are stacked smoothly. The tiles slide down and are securely stacked in two tiers on the tile arrangement table D.

As described above, in the present invention, a window 4a is provided in the center of the guide part 4 formed in a curved and inclined shape on the front part of the tile holder 3, and a window 4a is provided in the center part of the guide part 4, which is rotatable around the pin 5'. By providing the auxiliary guides 5, the problem of the tiles falling vertically onto the tile alignment table D is resolved, and instead of being provided on both sides of the guide portion 4 of the tile holder 3 as in the conventional case. Guide plates 2a are provided in a screen-like manner protruding from the front portions of both sides of the tile feeding table 2, and the lower end portions are formed to have a length corresponding to the upper ends of the tiles stacked in two levels on the tile alignment table D. This makes it possible to completely prevent tiles from shifting sideways, and eliminates the drawback of the tile feeding device, which has been the most frequent problem in fully automatic mahjong tables.
