Description

DETAILED DESCRIPTION OF THE INVENTION The present invention sequentially detects the posture and orientation of the tiles transferred after being mixed, and converts the tiles other than the face-down tiles to castle wall tiles ( The present invention relates to a method for detecting the posture of tiles in an automatic mahjong table used to correct the required number of tiles to the face-down state necessary to form a two-tiered state.

An automatic mahjong table is already well known that automates a series of operations in which tiles are mixed on a turntable, all of the mixed tiles are turned face-down, and castle wall tiles are formed and covered by the face-down tiles.

On the other hand, Japanese Patent Application No. 57-215503 filed by the present applicant
The invention in issue involves changing the orientation of all the tiles mixed on the turntable to a position other than standing tiles, and at the same time correcting the orientation.
These tiles are sent from the turntable onto the transfer conveyor, and the tiles that are transferred in the horizontal 1j sushi posture and the horizontally fallen posture are corrected to the face-down state required to form castle wall tiles. A posture correction device that can improve posture has been proposed. This posture correction device detects the posture of the transferred tiles in advance, and based on this detection, the table corrects the tiles other than the tiles to the face-down posture of It is configured so that the tiles can be sent out sequentially to the table.

Therefore, the present invention has the following advantages: - The posture of the tiles in an automatic mahjong table that is used to accurately detect the posture of the tiles transferred to the posture correcting device and control the operation of the posture correcting device based on this detection. This is intended to provide a detection method, and its purpose (posture of one tile) is to transport tiles in a horizontal position and horizontally in a line on the same side of the formal dress.
A permanent magnet movably provided in front of the posture correction device is moved by a relative reaction with the magnetic material embedded in the transferred tiles, and the movement of the permanent magnet causes the movement of the first transmission type sensor. While avoiding emitting or blocking the optical path, a second sensor installed separately from the above-mentioned transmission type sensor is detected by a tile placed in a sideways position among the transferred tiles.
The optical path of the first and second transmissive sensors is cut off, and the posture and front and back orientation of the tiles are detected by a combination of electrical signals applied to the opening and closing of the optical paths of the first and second transmissive sensors. This is achieved using a posture detection method.

Embodiments of the method of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a conveyor 4 for transporting tiles 1 is provided between a turntable 2, which is a member for mixing tiles 1, and Haskera 1 to 3, which are components of the figure 9A correction device. This transfer conveyor 4 is provided with a guide frame 5 (=j) so that the tiles 1 sent out from the turntable 2 can be reliably transferred to the basket 3 side.The rotating shaft 6 of the basket 3 is connected to the motor ( (not shown), and its rotation angle in the forward and reverse directions is controlled by the motor.
As shown in Fig. 2, the Haskellah h3 has one surface that receives the tile 1, and two surfaces that do not send out the tile 1. A7-
It is controlled so that it can stop at a position facing the delivery end 4a of No. 4, and is provided with a detection section 7a for detecting that position. Furthermore, the basket 3 is provided with a sensor 7b that detects whether the tiles 1 are stored in the basket 3.

In the figure, reference numeral 8 denotes a door rotatably provided on each of the two surfaces of the basket 3 through which the tiles 1 are sent out, to prevent the tiles from falling off, and this door 8 (j) is held by a retainer 9.

Next, we will explain how to detect the attitude of the tiles 1 that have been sent out onto the transfer conveyor 4 mentioned above (the attitude of the tiles lying sideways or flattened, as well as the orientation of their front and back sides). .

1M and 3, first and second transmissive lenses are placed in front of the bus grip 3 mentioned above in the passage for the tiles 1 to advance on the top 7-4 to the conveyance compactor 7-4. 11.12 is provided.

The first transmission type lens 11 is located directly below the transfer comparator A7-4, and its component is a light emitting diode i.
La and E1 to transistors 12b are attached to a holding frame 13 provided below the transfer controller \2 4. Inside the holding frame 13 is a permanent magnet 14 that is movable in the vertical direction.
This permanent magnet 14 is normally placed at a position 1 gi'c away from the optical path of the transmission type mirror 1-11, and the holding frame 13 is magnetically separated from the fixed base 15 side. It is made of a non-magnetic material that can be shielded, and is designed so that the direction of the magnetic flux of the magnet 14 is directed onto the transfer conveyor 4. In addition, as shown in FIG. 4, in the tile 1, a magnetic material 10 such as an iron piece is buried at a certain position on the back side 1a. The installation position is further restricted.In the illustrated case, the IC and permanent magnet 14 are placed in the magnetic field of the tile 1, which has been transferred in a horizontal position facing left in the figure, as shown in FIG. 4(d). It is necessary that the body 10 is set at a position where it passes through the area above the center of the permanent magnet 17'I, and this permanent magnet 14 is movable by the direct relationship between the magnetic body 10 and the magnetic body 10. It is said that the first
The optical path of the transmission type sensor 11 can be opened. On the other hand, the second transmission type sensor 41---12 is composed of a light emitting diode 12a mounted opposite to the side wall of the guide frame 5, and a hole 1 to a run sister 12b. is moved in a horizontal position and is blocked by the L-shaped tile 1, but the tile 1 in the horizontal position is set at a height that does not block it and is -CO.

The optical path of the first transmissive lens 11 and the second transmissive sensor 12 arranged as described above widens depending on the attitude and front and back orientation of the transferred tile 1. , these electrical signals are input to a combination controller, and according to instructions from this controller, the above-mentioned basket 3 is rotated as required, and the li'! '1's posture can be corrected to a regular face-down tile state.

Immediately J3, detected position "1" indicates that tile 1 has progressed.
Electrical signal and first and second transmission 41゛1Hinley-1
A logical condition is created by combining the on/on electrical signals due to the opening between the optical paths 1 and 12, and depending on this logical condition, the leg is tilted sideways or horizontally. −
Determine if there is a C, and the state of the front and back sides, and use this determined information to write down the combination.
All you have to do is give a rotation command to Basketball 3 by the required angle so that it takes the pose of the tiles.

Regarding the detection and correction of the tile posture explained above, 1.
! l! Each detection example will be explained in detail.

If the transferred tile 1 is a normal face-down tile as shown in FIG. Since the distance between the two sensors is 1), the optical path of the second transmissive sensor 12 is open, so both sensors 1
The output of 1.12 is Δoff-on. Therefore, in the case of this off-on electrical signal condition, the combo player remembers that it is tile 1 or the normal face down tile posture.
No rotation command is issued to the basket 3. Tile 1 is the same figure (
As shown in b), when the sensor is tilted sideways to the right in the figure, the optical path of the first transmission type sensor 11 is blocked by the permanent magnet 14 (because the distance tq11 between the magnetic body 10 and the permanent magnet 14 is human - C)
Since the optical path of the second transmissive sensor 4/12 is also blocked by the tile 1, the outputs of both sensors 4/12 are OFF/OFF-C. Therefore, based on this off-off electric signal, the computer issues a command to rotate the hand grips 1 to 3, for example, by 90 degrees in the timing direction. When the tile 1 is lying horizontally with its face up as shown in FIG. , Also, since the optical path of the second large-over type sensor 4-12 is also open, the outputs of both sensors 1,1=11.12 are on-on.

Therefore, based on this on-on electricity No. 1Δ, a command to avoid rotating the Koninbi coater (Yuhasuketsu l-3) by 180 degrees is generated.Also, the tile 1 is as shown in the same figure (d). I: In the case of sideways orientation (J, first), the optical path of the through-through sensor 11 is open, and the optical path of the second through-sensor 12 is blocked by the tile 1. The output of sensor 1 1.12 is Δon off -C. And -C5 based on this on-on electric signal: Issues a command to rotate 90' in the downward direction.

In the embodiment described above, the C path of the first transmission type sensor--11 is always blocked by the permanent magnet 614. ; p, I+
-C can also be implemented as if it were open. Also,
As shown in the figure, an immersion type sensor is installed at the detection position of tile 1 to detect the presence of tile 1.

As described above, the present invention is advantageous in quickly correcting the individual tiles transferred after being mixed into the normal face-down tile posture, and is also useful for use. Sen (No - is 3 of 1 type (P) is good) There is a lot of uniformity, ga, of course there is no hassle of adjustment, and changes in the environment such as temperature and humidity are good. It is extremely effective in improving the inherent capabilities of an automatic mahjong table, such as being able to perform accurate detection without being influenced by
