Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a tile feeding device in a fully automatic mahjong table.

Conventionally, the automatic mahjong tables provided are designed so that the tiles that have been put in are once stirred in a stirring device and then sent out by a delivery device, and the sent out tiles are arranged on a conveyance device by an alignment device. .

However, such a conventional tile dispensing device has a complicated mechanism and is prone to malfunctions, so there has been a desire for improvement.

In other words, due to the high temperature and humidity that is unique to Japan, there is a high incidence of problems such as belt stains, stretching, and cutting, and therefore it is necessary to constantly wipe off the stains, and from a maintenance standpoint, the above-mentioned problems occur during games. In this case, repair could only be done by an engineer who is familiar with mahjong machines, and this was a huge loss for the mahjong players.

The object of the present invention is to provide a tile dispensing device for a fully automatic mahjong table that can dispense tiles reliably and quickly while avoiding complicated mechanisms. Specifically, a tilting table rotating in the same direction as the turntable and having different rotational speeds is provided in the center of a turntable that rotates horizontally, and a turntable close to the outer periphery of the tilting table is provided at a constant interval. A posture selection section is formed in which a plurality of magnets are embedded, and a side wall is provided along the outer periphery of the posture selection section, separate from the turntable, so that when the inserted tiles reach the highest position on the tilting table, the tiles are The posture of the tiles is corrected by the action of the magnet installed in the turntable and the magnet of the posture selection section, and the tiles (tiles in the positive direction) that are forwarded by the turntable are placed in one place and placed in the tile discharge gutter. The tiles are ejected outward from the posture selection section and sent into a chute close to the side wall by the extrusion rod of the tile direction changing section connected to the tile ejection gutter, and the sent tiles are turned by the rotational force of the turntable. The images are arranged in a chute.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

The figure shows the movement of the tile when it is pushed out onto the posture selection section near b-b (within the second distribution zone) in Fig. 1 with its surface facing down (sideways);
FIG. 6 is a diagram showing the positions of tiles on the posture selection section near c-c in FIG. 1.

Reference numeral 1 denotes a turntable, and a tilting table 4 separate from the turntable 1 is provided in the center thereof, and a plurality of magnets 2 are embedded in the turntable 1 close to the outer periphery of the tilting table 4.

The magnet 2 is attached to the tile P as shown in FIGS. 4 to 6.
Together with the magnet 2' installed in the holder, the attitude of the tile P is corrected, and together with the rotation of the turntable 1, the tile P is reliably sent out.

Reference numeral 3 denotes an attitude selection section provided along the outer periphery of a tilting table 4 provided at the center of the turntable 1, in which a magnet 2 is embedded, and is carried upward by the rotation of the tilting table 4. If the magnets 2' installed inside the tile P have their N poles facing downwards as shown in Figure 4, they will repel each other because the N poles of the magnets 2' in the posture selection section 3 are facing upwards. When the tiles match, the tiles P are pushed back onto the tilting table 4.

Reference numeral 4 denotes a tilting table which rotates in the same direction as the turntable 1 and serves to push out the inserted tiles P and the tiles P pushed back from the posture selection section 3 onto the posture selection section 3 of the turntable 1 again.

Reference numeral 5 denotes a side wall, which is the attitude selection section 3 of the turntable 1.
The distributing member 6 is provided vertically along the outer periphery of the distributing member 6, and a distributing member 6 is provided at the inner bottom thereof, protruding inwardly so as to gradually become wider in the direction of rotation, and an upper guide 6' is provided.

Reference numeral 7 denotes a guide plate that guides the tiles P pushed out onto the attitude selection section 3 of the turntable 1 by the tilting table 4.
The tile P is pushed back and falls onto the tilting table 4, and while rotating together with the tilting table 4, it works to change the direction and posture of the tile P, and the mounting portion 7'
One end is fixed to the side wall 5 via.

8 is a first distribution zone, and the tiles P with their surfaces facing upward are pushed back to the tilting table 4 in the first distribution zone.

8' is the second distribution zone, where it is pushed out onto the attitude selection section 3 in a sideways state with its surface facing down (see Fig. 5), and as it rotates with the magnets 2 and 2' attracted to each other, The distribution member 6 provided on the side wall 5 protrudes gradually wider in the direction of rotation, so that the tiles P
is pushed out inward (towards the tilted table), finally falls onto the tilted table 4, and is sent upward again.

Reference numeral 9 denotes a tile discharge gutter, through which only the tiles P sent upward by the tilting table 4 and pushed onto the posture selection section 3 in the positive direction pass; The passage is performed by rotating the turntable 1.

Reference numeral 10 denotes a tile direction changing section, in which a sensor S detects a tile P passing through a tile discharge gutter 9, rotates a motor 11, and the extrusion rod is rotated 90 degrees by the motor 11, turning the tile right sideways. It is designed to push out in the direction.

Reference numeral 13 denotes a chute, which is provided on the outside of the side wall 5 through which the tiles P pushed out by the extrusion rod 12 pass sideways, and is designed to prevent the tiles P from being sent into the entrance of the chute 13 in an incorrect posture. A shutter 14 is attached to the chute 14, the bent portions are connected via a corner 15, and all movement of the tiles P within the chute 13 is performed using the rotation of the turntable 1.
When a predetermined number of tiles P are lined up, sensor S ₁ senses,
A transfer device 16 provided outside the chute 13 is commanded, and the transfer device 16 aligns the objects on an alignment table (not shown).

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

When the game ends and the tiles are thrown onto the tilting table 4, the turntable 1 and the tilting table 4 start rotating.

The inserted tiles P are concentrated at a lower position on the tilting table 4, but are sent to a higher position by rotation, and are the tiles P closest to the magnet 2 embedded in the posture selection section 3, with the surface facing downward. is attracted and rotates in the direction of the tile ejection gutter 9 along with the rotation of the posture selection section 3.
As shown in FIG. 5, when the tiles P are attracted sideways, they are pushed inward by the sorting member 6 in the second sorting zone 8' and fall.

Also, as shown in FIG. 4, even if the tile P tries to be pushed onto the posture selection section 3 with its surface facing upward, the repulsion of the magnets 2 and 2' will push the tile P onto the tilting table 4. It is pushed back, once rotated to a lower position, reversed by the guide plate 7, and sent upward again.

Therefore, the tile P shaken off from the posture selection section 3
naturally returns to its normal position while rotating on the tilting table 4, and is pushed out of the tile ejection gutter 9, and the pushed out tile P enters the tile direction changing section 10, forming a cross shape as shown in FIG. When the tile P contacts a piece of the extrusion rod 12, the sensor S operates to rotate the motor 11, and the extrusion rod 12, which is linked to the motor 11, rotates by a predetermined angle (90 degrees) and the tile P contacts. into the chute 13.

The fed tiles P are fed in sequentially as shown by the arrows in FIG. transferred device 1
6 on the alignment table.

As described above, the present invention uses the difference in the rotation direction and rotation speed between the turntable and the tilting table, as well as the magnets embedded in the attitude selection part of the turntable and the magnets installed inside the tiles. It is possible to complete the alignment while being reliably stirred within the interior, avoiding a complicated structure and achieving an inventive step that reduces costs.
This is a novel tile dispensing device.
