The present invention relates to a ball payout device for a pachinko machine.
[0002]
[Prior art]
Conventionally, as a ball dispensing device of a pachinko machine, a plurality of supply passages through which the pachinko balls continuously flow down, and a plurality of rotating bodies having ball mounting surfaces that face the supply passages and receive the pachinko balls one by one, It is known to have a discharge passage through which pachinko balls in each supply passage are discharged by rotation of the rotating body. The ball payout device having such a configuration is provided with a pachinko ball detection switch corresponding to each of the plurality of ball passages of the discharge passage partitioned by the partition wall in order to count the number of payouts of the pachinko balls.
[0003]
On the other hand, recently, a guide portion is provided in the discharge passage so that the minimum number of pachinko ball detection switches as described above is required, and the pachinko balls paid out to the plurality of ball passages by the guide portion are discharged while converging in one line. What has been proposed.
[0004]
[Problems to be solved by the invention]
By the way, in such a conventional ball dispensing device, since the discharge passage is partitioned into a plurality of ball passages by the partition wall, the pachinko ball is inevitably converged by the guide portion after being released from the rotating body (after the dispensing). I had to do it. For this reason, it took time for the distance between the rotating body and the guide portion to become longer and converged, and a time lag was likely to occur in the discharge of the pachinko balls. In addition, pachinko balls paid out from a plurality of ball passages collide with each other up to the guide portion to cause clogging of the balls, and the length of the discharge passage increases the size of the entire device and requires a large installation space. There were problems such as being. On the other hand, when trying to minimize the space in the passage merge, it has to be merged abruptly, and as a result, the pachinko balls that have been paid out collide with each other, causing problems such as clogging of the balls .
[0005]
Also, since the ball pressure of the pachinko ball waiting in the supply passage is directly applied to the rotating body, a heavy load is applied to the drive motor, the drive motor breaks down due to short-term use, and smooth pachinko ball payout cannot be performed. It had the problem of being.
[0006]
Accordingly, the present invention has been made to solve the above-mentioned problems, and eliminates the load applied to the rotating body, forcibly converges pachinko balls received by the ball receiving rack, and pays out the entire apparatus to the discharge passage. An object of the present invention is to provide a ball payout device for a pachinko machine that can be downsized and can stably discharge a pachinko ball without a time lag during discharge.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a ball payout device for a pachinko machine according to the present invention includes a plurality of supply passages in which pachinko balls continuously flow down, a rotating body facing each of the supply passages, and rotation of the rotating body. In the ball payout device for a pachinko machine comprising a discharge passage through which the pachinko balls of each supply passage are discharged, the rotating body is provided with a ball feeding means in a spiral shape on the outer peripheral surface, and is positioned on the lower surface of the rotating body. And a ball receiving shelf for supporting the first pachinko ball adjacent to the supply passage adjacently.
[0008]
It is preferable that the ball receiving shelf is provided with a partitioning ridge having a height that does not support the ball center of the pachinko ball, and the pachinko ball overlaps the front and rear independently when the pachinko ball in the supply passage is supported. The starting width of the passage is less than 2 pachinko balls so that it converges smoothly.
[0009]
The ball shelves are characterized in that the heights of the pachinko balls when they are separated from the ball shelves are different, so that they are paid out in a more converged state and the fall timing is shifted.
[0010]
The ball receiving shelf is provided with an early separation portion by a notch or the like, so that the pachinko balls of the plurality of supply passages are isolated early from the ball feeding protrusion of the rotating body, and the timing of dispensing is shifted. Good.
[0011]
With the above configuration, when the pachinko ball waiting in the supply passage is supported by the ball receiving shelf, the ball pressure is not directly applied to the rotating body, so that the load applied to the rotating body is reduced. The rotation of the rotating body is smoothly performed, the pachinko ball can be paid out accurately, and the entire apparatus can be downsized.

Reference numerals 33 and 34 denote guide protrusions provided at the start end of the ball receiving shelf 18 so as to smoothly send pachinko balls in the supply passages 17a and 17b.
[0019]
Next, the payout operation of the ball payout device 9 having the above-described configuration will be described with reference to FIGS. 4 is a front view, FIG. 5 is a plan view, FIG. 6 is a side view, and (a), (b), and (c) in each figure show the same timing state. In FIG. 4A and FIG. 6A, the pachinko balls in the supply passages 17a and 17b are respectively supplied to the lower side of the rotating body 27, and the leading edge of the supply passages 17a and 17b is sandwiched between the partition protrusions 31. The pachinko balls B1 and B2 are fitted between the ball feeding ridges 26 and 26 and supported by the ball receiving shelf 18. At this time, the partition protrusion 31 has a height that does not support the center of the pachinko sphere, and the height positions of the pachinko spheres B1 and B2 are different. Therefore, as shown in FIG. Converged. When the stepping motor 24 is driven in this state and the rotating body 27 is rotated in the clockwise direction indicated by the arrow in FIG. 4, the pachinko balls B 1 and B 2 are supported by the ball receiving rack 18 and the ball feeding protrusion of the rotating body 27. 4 is moved to the position shown in FIG. 4B to FIG. 6B, and the pachinko ball B1 in the supply passage 17a is removed from the support of the ball feeding protrusion 26 by the recess 32 of the ball receiving shelf 18, and is discharged. It will fall to 19. At this time, the rotating body 27 is rotated by 220 °, and the light receiving and emitting elements 30a and 30b detect the light transmitting notch 29.
[0020]
When the rotating body 27 further rotates, as shown in FIGS. 4C to 6C, the pachinko ball B2 moves the ball receiving shelf 18 along the partition protrusion 31 by the ball feeding protrusion 26, and receives the ball receiver. It falls off the support of the shelf 18 and falls into the discharge passage 19. And it goes to the ball | bowl exit 15, being converged by the inclined surface 19b. At this time, the rotating body 27 is rotated by 140 °, and the light receiving and emitting elements 30a and 30b detect the light transmitting cutout 29.
[0021]
Further, originally, the pachinko balls B1 and B2 in the supply passages 17a and 17b are discharged at a rotation of 50 ° and 310 ° from the positional relationship, and the discharge timing on the supply passage 17a side is determined by the recess 32. Since it becomes faster, it is the timing of paying out with rotation of 140 ° and 220 ° provided with the light-transmitting notches 29, 29. Further, the payout height at which the pachinko ball on the supply passage 17b side is separated from the ball receiving shelf 18 is different from the payout height at which the pachinko ball on the supply passage 17a side is separated from the ball receiving shelf 18, so that it is substantially hemispherical. The discharge timing is later than the discharge timing of the supply passage 17a, and the pachinko balls delivered to the discharge passage 19 fall at substantially constant intervals, covering the difference in discharge timing due to rotation of 140 ° and 220 °. .
[0022]
In this way, the pachinko balls B1 and B2 in the two rows of the supply passages 17a and 17b that fall into the discharge passage 19 due to the rotation of the rotating body 27 are already converged at the time when they are supported by the ball receiving shelf 18, and the ball feed The protrusions 26 fall alternately into the discharge passage 19 and are discharged from the ball outlet 15 at regular timing without colliding with each other, and discharged to the discharge rod 12 while being counted by the ball detector 10.
[0023]
As described above, the ball dispensing device 9 according to the present embodiment supports the pachinko ball that is continuously waiting in the supply passages 17 a and 17 b while supporting the pachinko ball on the lower surface of the rotating body 27. Since the ball pressure applied to the rotating body 27 is reduced by moving, the rotating body 27 can be smoothly rotated and the load on the stepping motor 24 can be reduced. The stable operation of the stepping motor 24 can be maintained over a period.
[0024]
Further, by the partitioning ridge 31 having a height that does not support the center of the pachinko sphere, the starting width of the pachinko sphere discharge passage 19 can be made narrower than two pachinko spheres. can do. For this reason, the distance of the discharge passage 19 which converges can be shortened effectively without difficulty, and the whole apparatus can be easily downsized. And the pachinko ball falling to the discharge passage 19 can be discharged more smoothly in one row.
[0025]
In the above-described embodiment, the ball feeding means has been described as the ball feeding protrusion 26. However, a groove-like ball feeding means may be provided in a spiral shape on the outer peripheral surface of the rotating body.
[0026]
【The invention's effect】
