Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to an automatic mahjong tiles sending device capable of aligning and storing a set of mahjong tiles in a tray so that the front and back surfaces of the tiles sequentially sent to the tray can be aligned and transferred.

[Prior art]

Mahjongso has prepared a saucer for each Mahjong table to line up and store the used tiles after the game is over. Waiting for customers. At present, however, all the work for accommodating the tiles in the tray depends on the manual work of the workers.

[Problems to be Solved by the Invention]

When the number of tiles used is large, manual labor for tile storage requires a considerable amount of labor and time, and the tiles that are frequently used are washed and stored in the saucer at any time, so the labor of the employee is low. It will increase more and more. Recently, a device that can automatically mechanize the work of aligning the tiles on the tray and storing them (for example, Japanese Patent Application No.
A Mahjong tiles alignment / accumulation device according to the invention of No. 0-153763) has also been developed, but the tiles accommodated in the saucer are arranged such that the front and back sides are arranged in different directions. Or, there is a problem that they cannot be housed in an orderly manner so that they are face down, and it has been desired to develop a device capable of aligning the front and back sides and sending the tiles to the saucer.

[Means for solving problems]

The present invention has been made in view of the above points, and an object thereof is to set a set of mahjong tiles thrown into a hopper or the like on a transfer passage by aligning the front and back surfaces of the respective tiles during the transfer. It is an object of the present invention to provide an automatic mahjong tiles sending device capable of sequentially sending out a set of mahjong tiles to a tray and accommodating a set of them. Another object of the present invention is to provide an automatic mahjong tiles feeder which can be easily applied to the automatic mahjong tiles washing machine according to the invention of Japanese Patent Application No. 60-210212, which the present applicant has already applied for a patent. Especially. Therefore, the above object of the present invention is to provide a turntable for intermittently rotating a predetermined angle by providing a discharge tube in which the tiles are erected and dropped, and an accommodation port capable of accommodating one tile dropped from the discharge tube. And a supporting base arranged and fixed in proximity to the lower surface side of the turntable for supporting the tiles housed in the housing port, and a transfer passage connected to the discharge port formed in the support substrate, The accommodation opening is formed by penetrating a turntable rotatably fitted to the turntable and a small gear fixed to the lower surface of the turntable, and the small gear is concentric with the turntable and can be raised and lowered. The gear ratio of the large gear and the small gear, which is always meshed with the large gear installed on the rotary table, is eliminated by intermittently rotating the turntable at a predetermined angle from the position where the storage port on the turntable faces the discharge cylinder. Exit position When reaching up to 180 °, the rotation phase of the turntable is 180 degrees with respect to when it was facing the discharge cylinder, and the large gear is selectively coupled to the turntable and the support base. The discharge port is provided at a position separated from the discharge tube and under the rotation path of the storage port, and detects the front and back surfaces of the tiles falling from the discharge tube. The first detection sensor and the second detection sensor for detecting the tiles dropped on the turntable are provided, and the first detection sensor moves up and down the large gear, and the second detection sensor controls the turntable of the turntable. This is achieved by an automatic delivery method of mahjong tiles configured to control each drive.

One end of the crank portion 16a is placed under the action of the return spring 25, is axially attached 24 to the operating rod 23a of the solenoid 23, and the turning operation of the solenoid 23 causes the rotating body 16 to move as shown in FIG. It rotates in the direction and the large gear 14 is lifted and coupled to the turntable 4. When the solenoid 23 is off, the large gear 14 descends and is fixed to the bearing 6, that is, the support base 5 side, as shown in FIG. The ON operation of the solenoid 23 is performed by the signal from the first detection switch 3 described above. A discharge port 26 for discharging the tiles P moved by the turntable 4 is formed in the support base 5, and the discharge port 26 faces below the rotation passage of the accommodation port 10 and is 180 degrees from the discharge cylinder 2.
They are provided at positions spaced apart by a degree, and a transfer passage 27 is connected to the discharge port 26. The transfer passage 27 is preferably formed as a pipe, the transfer passage 27 extends in an L-shaped curve, and its horizontal passage portion 27a is on the side of a tray (not shown) for accommodating a set of mahjong tiles in an aligned manner. The tile P in the standing state, which has fallen from the discharge port 26, falls to the horizontal state at the time of entering the horizontal transfer portion 27a and is transferred to the saucer side in the state of the front tile or the face tile. It will be a matter. The transfer of the tile P is carried out by a push rod 28 which moves forward and backward by a known actuating means, and a hole 29 through which the push rod 28 is inserted is provided in the side wall of the transfer passage 27. Further, the transfer passage 27 is provided with a fourth detection sensor 30 for detecting the tile P that has fallen into the passage, and the forward movement of the push rod 28 is performed by the detection signal from the fourth detection sensor 30. Will start. In the figure, 31 is a fixing screw for fixing the rotary disk 8 and the small gear 9, 31 a is a screw hole, and 32 is an escape hole formed in the support base 5. Next, the operation of sending the tile P will be described based on the above-described embodiment. In FIG. 5, for example, if the front side a of the tile P faces the first detection sensor 3 side (right side in the figure) and falls from the discharge tube 2 as shown in FIG. 3, a detection signal is output, the solenoid 23 is turned on, the large gear 14 is connected to the turntable 4, and the two rotate integrally as a half. At the position where the turntable 4 is rotated half a turn, the tiles P are in the opposite direction (on the left side in the figure), and the transfer passage 27
The tile P that has fallen to the side falls horizontally and becomes a lying tile. On the other hand, if the back side b of the tile p faces the first detection sensor 3 side (right side in the figure) and falls from the discharge tube as shown in FIG. 2B, the detection signal from the first detection sensor 3 is Without
The solenoid 23 is in the off state, and the large gear 14
Is fixed to the support base 5 side apart from the turntable 4. Therefore, the turntable 4 in the state shown in FIG.
When the turntable 8 rotates, the turntable 8 rotates by the small gear 9 meshing with the large gear 14, so that the orientation of the tile P at the position where the turntable 4 is half-rotated is the same as the original orientation due to the reversing operation of the tile itself. The tile P that has fallen to the transfer passage 27 side falls horizontally to become a lying tile. In the above description, the turntable 4 and the large gear 14 are connected when the solenoid 23 is turned on, but this may be implemented so that the solenoid 23 can be connected when the solenoid 23 is off. And the rotation ratio of the pinion 9 is
It is selected so that the above-mentioned inversion operation of the tile P is correctly performed.
