Description

[Detailed Description of the Invention] The present invention relates to a tile dispensing device for sequentially dispensing tiles stirred in an automatic mahjong table in two stacks.

Two sets of mahjong tiles with pieces of iron or magnets embedded inside near the back are used, and one set of tiles is washed while stirring the other set of tiles during the game, and a predetermined number of tiles are stacked in two stacks. The automatic mahjong table is configured to form four sets of castle wall tiles, and after the tiles in the game are stored in a predetermined position at the end of the game, the waiting castle wall tiles are raised to a game ready state. It is well known.

In the automatic mahjong tables that are commonly used in the past, a method is adopted in which the tiles are taken out one after another after being stirred, a predetermined number of tiles are once aligned, and then a predetermined number of aligned tiles are stacked on top of that to form castle wall tiles. There is. In such a configuration, the first row of tiles is aligned and the entire group is displaced in the horizontal and vertical directions,
Next, a means for confirming the alignment of the tiles in the second row and placing them on the tiles in the first row was essential. As a result, the structure becomes complicated, which tends to cause trouble, and often goes against demands for lower device costs.

It is an object of the present invention to provide a tile dispensing device which stacks tiles taken out after stirring in two stages, changes the direction of the tiles, and dispatches the tiles.

The object of the present invention is achieved by the tile dispensing device described in the claims of the utility model registration.

The tile dispensing device according to the present invention reduces the steps and time required for forming wall tiles, enables quick and reliable two-tiered tile formation, and reduces the cycle time of the entire device. Further, there is no need to move a large number of aligned tiles simultaneously in the vertical direction, and the configuration can be simplified.

The invention will now be disclosed with reference to the accompanying drawings, which illustrate embodiments.

Referring to FIG. 1, which shows a plan view of the device according to the invention, and FIG. 2, which shows a partially cutaway side view, the device according to the invention is driven by an electric motor (not shown) through a suitable speed reduction mechanism. It is intermittently rotated in the direction of arrow 11 by a driven shaft 10. The rotation of the shaft 10 is caused by the gear group 12, 1.
Rotating arm 15 and rotating disk 16 via 3 and 14
Rotate each.

The rotating arm 15 rotates to the original position A while assuming positions A, B, C, and D without being hindered by the tile holder 17 and the tile holder 18, respectively. A tile pushing member 19 is arranged above the rotating arm 15. A support section 20 is provided at the rear of the extrusion member 19.
A sliding shaft 21 passing through the two is connected to each other. The sliding shaft 21 is pushed back to the right by the coil spring 22, but is moved forward in the direction of the arrow 23 immediately after the position C of the rotary arm 15. When such forward movement reaches the most extreme position, the engagement between the rotary arm 15 and the rear end of the member 19 is released, and the coil spring 22 returns the member to the illustrated position.

The tile holder 18 is guided by a link 24 attached to the rotary disk 16 into a guide groove 25 indicated by a broken line, and moves up and down. As shown in the diagram at the left end of FIG. 2, the top surface of the tile holder 18 is stopped at the initial position O, and then as the rotating disk 16 rotates as indicated by the arrow 26, it reaches the bottom dead center L _D. As the rotating disk 16 continues to rotate, it reaches the top dead center U _D and then descends to the original position O.

By using the device according to the present invention, two stacks of tiles P(×
The operation for forming 2) will be explained below.

A tile P is sent in from above in FIG. 1 as indicated by an arrow 27. The tiles P are sequentially fed in from a pre-stage conveyance device (not shown). The positions at which the tiles P are fed in this way are the upper surface of the tile holder 18 which is stopped at level O in the tile holder 17, and the lower side of the rotating arm 15 which is also stopped at position A. Yes (see Figure 2).

When a detector (not shown) detects and confirms that the tile P is securely placed on the tile holder 18 in the tile holder 17, an electric motor (not shown) begins to rotate, and the shaft 10 moves in the direction of the arrow 11. Rotate like. As a result, the tile holder 18 descends toward the bottom dead center L _D , forming a space for receiving the next upper tier of tiles. At the same time, the rotary arm 15 also rotates in the direction of the arrow to ensure the descent of the tile P, reaching position B and completing the first stage operation.

The tiles P in the second stage are also sent into the apparatus from the previous transport mechanism as shown in FIG. 1P in the same manner as described above. In this case, the back surface of the first stage placed on the top surface of the tile holder 18, which has already reached the bottom dead center L _D and has stopped, is at level O.
Since the rotary arm 15 is located at a position slightly lower than the position B and the rotary arm 15 is also at position B, it does not obstruct the entry of tiles in the second row. When it is detected that the tiles in the second stage are also placed in the correct position, the operation in the second stage starts.

The rotating disk 16 rotates from the bottom dead center L _D to the top dead center U _D
The tile holder 18 rises until the 2-tier stack of tiles P (×2) reaches the position shown in FIG. Meanwhile, the rotating arm 15 rotates from position B in the direction of the arrow and reaches position C.
Pushing member 19 is advanced in the direction of arrow 23 against spring 22. This rotation of the rotating arm 15 continues as indicated by the arrows and. Such extrusion member 19
By this movement, the two-stage stacked tiles P(x2) are moved forward in the direction of arrow 2B and placed on the schematically illustrated rear-stage tile transport mechanism 29. When the rotating arm 15 separates from the rear end of the tile pushing member 19, the pushing member 19 returns to its original position by the spring 22, while the rotating arm 15
reaches position A and completes the two-tiered tile formation and delivery process.

A well-known control method is adopted to stop and restart the electric motor at a desired position, and the motor can be stopped and restarted at positions O, L _D , _UD of the holder 18 and positions A, B of the rotary arm 15, etc. It is done smoothly.

Although the invention has been disclosed in conjunction with embodiments thereof, it will be obvious that many variations and modifications may be made within the scope of the invention.
