Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pachinko ball rotary transfer device, in which a plurality of pachinko balls, which have become safe balls by rolling down a rolling surface, are provided on a vertical plane. In a device in which the balls are arranged in a row in a lateral supply path and flow down, and the spheres are separated one by one by a rotating disc rotated by a motor and conveyed to an arbitrary position, several balls arranged in the supply path are described. Of the pachinko spheres, the leading sphere is prevented from occasionally clogging phenomenon in which the leading sphere is pressed by the succeeding sphere and does not enter into the U-shaped sphere receiving hole provided on the peripheral edge of the rotating disc. Even when the balls are continuous, one pachinko ball is always smoothly inserted into the ball receiver so that the pachinko balls can be rotatably conveyed by the rotating disk.

(Prior Art) Conventionally, a plate surface a having a vertical plane b as shown in FIG.
A circular hole c having a wall f surrounding the hole excluding the inflow port d and the outflow port e is formed, and the rotating disk h is fixed to the motor shaft 9 passing through the center of the circular hole c. U-shaped ball receivers j are formed on the arcuate ball receivers i, i at substantially equal angular intervals at the peripheral edge of the upper component m between the supply port k and the inflow port d provided on the vertical plane b.
And a lower part piece n, the ball guiding path L is provided. Normally, the rotating disk h having the ball receiver j is rotating, so that the ball B which cannot be transported is accumulated in the ball guiding path L. However, when the safe spheres B are continuously generated and a few of them flow into the sphere guide passage L from the supply port k, the first one contacts the arcuate sphere receiving piece i, and the following several spheres become the first sphere. As shown in FIG. 6, if the pushing pressure causes a primary bite as shown in the figure and the ball receiving j is slightly delayed, the rotation speed of the rotating disk h does not change due to the motor drive. A secondary biting occurs between the rear corner of j in the rotational direction and the upper component m,
Although the motor is supplied with electric current, the motor shaft 9 and the rotating disc h stop rotating, which causes a problem that the sending out of the prize ball is impossible, and further the motor is burned out. However, even if this phenomenon of ball clogging occurs once every few days, the reliability of the pachinko ball becomes unreliable, so good measures must be taken.

(Problems to be Solved by the Invention and Purpose of the Invention) The present invention has an object to solve the problems by eliminating the above-mentioned phenomenon of ball clogging.

(Means for Solving Problems) The present invention has been made to meet the above-mentioned object, and more specifically, a circle provided with a surrounding wall at the periphery of a hole excluding an inlet and an outlet on a plate surface of a vertical plane. A rotary transfer device having a hole and a rotary disk provided with a U-shaped pachinko ball ball receiver formed so as to substantially match the surface of the vertical plane with a motor shaft passing through the center of the hole. In the above, a supply path for laterally arranging several spheres to flow is constituted by a lower component piece and an upper component piece, and the pressure at which the lower end is slightly separated from the hole edge of the circular hole at the abutment of the supply path. The blocking piece is provided on the vertical plane, and a ball guiding passage opening to the inflow port is provided between the pressure blocking piece and the lower component piece.

(Embodiment) FIGS. 1 to 3 of the accompanying drawings are front views showing an embodiment of the present invention, and FIG. 4 is a vertical sectional side view of FIG.

Reference numeral 1 is a plate surface having a vertical plane 2 in which a circular hole 3 is formed.
And a surrounding wall 6 is provided on the peripheral edge of the circular hole 3 excluding the inflow port 4 and the outflow port 5, and a motor shaft 7 passing through the center of the circular hole 3 is formed.
Is fixed through the center of the rotating disk 8 that rotates in the circular hole 3, and several U-shaped ball receivers 10 are attached to the surface of the rotating disk 3 which is substantially aligned with the vertical plane 2 described above. Are formed at substantially equal angular intervals.

According to the present invention, the ball receiver 10 of the rotating disk 8 has the above-mentioned construction.
In addition, according to the configuration in which the safe spheres B are supplied one by one from the inflow port 4 without causing troubles, several spheres B are provided between the supply port 11 and the inflow port 4 provided on the vertical plane 2. The supply passages 12 which flow side by side in a lateral direction are constituted by an upper component piece 13 and a lower component piece 14, and a pressure blocking piece 15 is projected from the vertical plane 2 at a substantially horizontal collision of the supply passage 12. Provided between the weir piece 15 and the folding piece of the lower component piece 14 and opening into the inflow port 4 described above.
6 is provided, and a pressure relief opening 17 is provided between the upper component piece 13 and the pressure blocking piece 15 so as to match the upper portion of the ball flow down passage 16.

The lower end of the pressure blocking piece 15 is terminated at a position separated from the hole edge of the circular hole 3 by about 1/3 of the diameter of the sphere B, and the lower end of the circular hole 3 and the circular hole 3 are closed.
A ball escape port 18 is formed between the edge of the hole. Lower piece 1
The folding piece constituting the spherical flow down passage 16 of No. 4 has a structure that is slightly inclined in the rotation direction of the rotating disk 8.

In this embodiment, even if several spheres B continuously flow into the supply passage 12 from the supply port 11 and the second sphere B- ₂ at the top comes into contact with the pressure blocking piece 15, the first sphere B at the top. _-1 contacts the lower surface of the arcuate sphere receiving piece 9 of the rotating disk 8 in the sphere flow-down path 16, and the pressures of the spheres B _{-2 to} B _-4 effectively cause the sphere B _-1 to move in the sphere flow-down path 16. The pressure of the balls B- ₂ to B- ₄ does not act on the ball B- ₁ at the top first position because the pressure does not act so as to make it flow down to the ball receiver 10 and push against the pressure blocking piece 15. (Figs. 1 and 2). Since the pressure blocking piece 15 has its lower end raised and the ball escape port 18 is provided below the lower end,
Secondary entrapment does not occur unlike the unmodified device shown in FIG.

As shown in FIG. 3, when the ball B _-1 at the top first position fails to enter the ball receiver 10 of the rotating disk 8 (there is almost no failure to enter), it hits the corner on the rear side in the rotation direction of the ball receiver 10 and makes an arc. When attempting to move to the ball receiving piece 9, the ball B- ₂ at the top second place is slightly pushed up. The ball B- ₂ is pushed up to the pressure relief port 17, which is outside the scope of the invention.

(Effects) The present invention has the operations described in the above embodiments, and the drawbacks of the configuration shown in FIG. 5 can be easily eliminated, and the rotating disk 8 and the motor shaft 7 can be stopped and safe due to ball clogging. There is an effect that the above-mentioned defects of the pachinko machine such as delay in ball delivery can be improved.
