Description

[Detailed description of the invention] This invention uses a quadruple double-stacked tile alignment device in a fully automatic mahjong table to push the tiles placed in two-stacked stacks on the alignment table sideways to form 17 pairs. This invention relates to a push-out type lifting mechanism in a fully automatic mahjong table that aligns objects accurately and pushes them out to the tabletop alignment section.

Until now, various types of fully automatic mahjong tables have been provided, and each mahjong table is equipped with a characteristic tile stirring device, tile feeding device, tile alignment device, etc.

In this invention, the tiles sent out from the tile sending device fall onto the tile arrangement table, and when the two-tiered stacking is completed, the tiles are pushed out sideways on the tile arrangement table using four devices to align the tiles. After being extruded and placed on the tabletop alignment section, it is pushed up onto the mahjong tabletop by a lifting mechanism.Since the four mechanisms have the same structure, one mechanism will be explained with reference to the drawings.

The perspective view and FIG. 4 are enlarged perspective views of the on-board alignment parts, and 1 and 1' are chains that are rotatably provided vertically in parallel at predetermined intervals via sprockets 9 _{and 93} . , four tile feeding devices and the tile extrusion section 5 are interlocked by one driving device 23.

Reference numeral 7 denotes a tile alignment table, which is installed parallel to the chain 1 in a manner that gradually slopes upward from the front part of the tile sending device A so as to reach the facing part.

S, S ₁ , and S ₂ detect the movement of the actuating unit 2 and transmit the sending of tiles, stacking of tiles in two levels, push-out alignment of tiles, and movement of tiles to tabletop alignment unit 11 after alignment to the drive device 23. It is a detector that

With the above structure, the operation of the present invention will now be explained.

As shown in Figure 2, when the tiles sent out from the tile sending device are stacked in two layers on the tile sorting table 7, the detector _S2 detects this and the drive device 23 is activated, causing the chains 1, 1' to rotate in the direction of the arrow a. As the chain rotates, the slide section 6 moves in the same direction together with the slide plate 3, which is attached so that it can slide freely up and down in accordance with the inclination of the tile sorting table 7, and the tile pushing section 5, which is attached to the slide section 6 via the connecting section 4, also moves.

Therefore, the tile extrusion unit 5 extrudes the two-tiered tiles 8 to the side (to the position of the tiles indicated by the dashed line). When the detector S detects that 17 pairs of tiles stacked in two stacks have been arranged in parallel on the tile alignment table 7, the drive device 2
3 works, and 17 pairs of tiles stacked in two levels are placed in the tabletop alignment section 11.
When the tile is pushed out by the tile extrusion section 5 to the position immediately before reaching the position, the detector _S3 operates to stop the drive device and wait at this position until the game in progress ends. .

When the game is finished, the tiles on the table are put into the stirring device, and a switch button provided at a predetermined position on the table is pressed, the chain rotates and the waiting tiles are pushed onto the tabletop alignment section 11. However, since the upper end of the tile alignment table 7 is located below the tabletop alignment section 11, it is necessary to lower the tabletop alignment section 11 to the same position as the top end of the tile alignment section 7.
Vertical movement lever 13 and rotation lever 1 provided at the bottom of
Reference numeral 5 denotes a mechanism for lowering one end of the tabletop alignment section 11 to the same position as the upper end of the tile alignment table 7, and the operation of this mechanism will be explained.

The lever push rod 10 attached to the chain 1 moves with the rotation of the chain 1, but since this lever push rod 10 moves in front of the tips of the 17 pairs of tiles being pushed out, the frontmost tile is Before reaching the upper end of the tile arrangement table 7, push the rotation lever 15.

The pushed rotary lever 15 rotates, and this rotation causes the vertically movable lever with the pulley 12' to rotate in the direction of arrow b, thereby aligning the tabletop alignment section 11 about the shaft 17. One end is inclined and lowered to the same position as the upper end of the tile alignment table 7, so that the 17 sets of tiles are pushed up onto the tabletop alignment section 11 one after another.

At the same time as the lifting of the 17 pairs of tiles onto the tabletop alignment section 11 is completed, the drive device 23 operates to rotate the chains 1 and 1' in the opposite direction, and the chains 1 and 1' are rotated by the lever pusher rod 10 that moves together with this. The lever 15 also returns to its original position.

Along with this, the vertically movable lever 13 also returns to its original position, so that the tilted state of the tabletop alignment section 11 also returns to its original position, and the 17 pairs of tiles stacked in two levels complete their alignment on the mahjong tabletop.

When the game ends, the tiles are put into the stirring device and the lid is closed, the stirring, pushing out, arranging, etc. operations are started again.

The above operations are explained for one device, but in reality, the same four devices perform the same operation at the same time using detectors S, S ₁ , S ₂ , and S ₃ . The 136 tiles are placed in four places (east, south, west,
North) completed the alignment in a short time.

As described above, the present invention is an innovative tile alignment device with a push-out type lifting mechanism that has a simple structure and can complete the alignment of tiles in a short time.
