DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional pachinko ball dispensing device described above, the rotation of the drive motor is temporarily changed due to a change in voltage, or the flow is changed by a small diameter ball, a dirty pachinko ball, or the like. If there is a change, there is a problem that the timing of the pachinko ball that engages with the recess of the sprocket shifts, causing ball catching, damaging the sprocket and stopping its rotation, making it impossible to pay out the pachinko ball. It was An object of the present invention is to provide a novel pachinko ball dispensing device that does not cause ball biting even if the rotation of the drive motor changes or the flow of the pachinko ball changes.

[0004]

In order to achieve the above object, a pachinko ball dispensing device of the present invention comprises a supply passage through which pachinko balls are continuously supplied, a rotary body having a plurality of blades, It is composed of a drive motor for rotating the rotating body, and a discharge passage through which the pachinko balls paid out by the rotation of the drive motor are discharged, and an arcuate guide portion concentric with the rotating body is formed on the downstream side of the supply passage. , The blade of the rotating body has an upper surface formed as an arc surface for receiving a pachinko ball,
The lower surface is provided with an arcuate recess that is approximately equal to the diameter of the pachinko ball,
Further, the tip portion is set so as to face between the frontmost pachinko ball and the next pachinko ball when the frontmost pachinko ball in the supply passage is received by the arcuate recess.

[0005]

The leading edge of the pachinko ball waiting in the supply passage is received by the arc upper surface of the blade of the rotating body.
When the rotating body is rotated by the drive motor in this state, the next blade faces between the latest pachinko ball and the next pachinko ball, receives the next pachinko ball on the upper surface of the arc, and circles the latest pachinko ball. While digging into the arcuate recess, it is discharged along the arcuate guide and discharged into the discharge passage.

Further, the engaging pins 15 and 15 projectingly provided at both ends of the connecting rod 11 are provided with the recessed hole 16 of the switching lever 9 and the through hole 17 of the link member 12.
The switching lever 9 and the link member 12 are connected to each other by being loosely fitted in each. The switching lever 9 is rotated to a position for closing the ball removing passage 8 shown by the solid line in FIG. 2 when the ball removing solenoid 13 is not operated, and as shown by the chain line in the figure by the operation of the ball removing solenoid 13. The discharge passage 7 is rotated to a position where it is closed.

Next, a pachinko ball dispensing device 6 according to the present invention will be described with reference to FIGS. The dispensing device 6 includes a box-shaped case body 18 attached to the mechanism plate 3. The case body 18 includes a front frame body 18a and a rear frame body 18b.
Are divided into two parts, and are joined together with a partition plate 19 in the center, and fastened with screws 20 to be integrated.

Supply passages 21 and 21 for continuously supplying the pachinko balls of the guide passage 5 are formed at upper inner positions of the front frame body 18a and the rear frame body 18b, respectively. Also,
A semi-circular rotary member storage unit 2 is provided downstream of the supply passages 21 and 21.
2, 22 are formed, and further, pachinko ball discharge passages 23, 23 are formed below the rotating body housing portions 22, 22.

On the other hand, a drive motor 24 is attached to the rear surface of the rear frame member 18b, and its motor shaft 25 penetrates through the respective rotary member accommodating portions 22 and 22 and its tip is pivotally supported by a bearing 26. . Then, the two rotating bodies 27, 27 are fixed to the motor shaft 25 so as to be located in the respective rotating body housing portions 22, 22. The bearing 2
6 is fitted and fixed to a tubular portion 28 formed on the inner surface of the front frame 18a.

The rotating bodies 27, 27 are provided with two blades 30a, 30b which are bilaterally symmetrical with respect to the shaft holes 29, 29 fitted into the motor shaft 25.
The upper surface of each of a and 30b is formed as an arcuate surface 31 for receiving a pachinko ball, and the lower surface is formed as an arcuate recess 32 having a diameter substantially equal to that of the pachinko ball. Further, the tip end portion is set so as to face between the most advanced pachinko ball and the next pachinko ball when the most advanced pachinko ball of the supply passage 21 is received by the arcuate recess 32. Furthermore, the rotating body storage unit 2
Arc-shaped guide portions 33, 33 concentric with the rotating bodies 27, 27 are formed on the downstream side of the supply passages 21, 21 that communicate with the rotors 22, 22. In addition, the leaf springs 3
4, 34 are attached. In addition, the two rotating bodies 27,
27 are fixed to the motor shaft 25 at positions different from each other by 90 degrees.

Denoted at 35a and 35b are pachinko ball detection sensors integrally attached to the substrate 35.
It is located on the upstream side of 23. The detection sensors 35a, 35
In b, the light from the light emitting portion is received by the light receiving portion to detect a pachinko ball.

The operation of the pachinko ball dispensing device 6 of the present invention thus constructed will be described with reference to FIG. As shown in FIG. 6A, the most distal pachinko ball B ₁ of the supply passage 21 is the arc upper surface 31 of the one blade 30 a of the rotating body 27.
When the rotating body 27 rotates in the direction of the arrow by the rotation of the drive motor 24 in the state of being supported by, the leading edge of the pachinko ball B ₁ is moved to the other blade 30b as shown in FIG. 6B.
It is received and supported by the arcuate recess 32. In this state, the rotating body 27 is further rotated so that the tips of the blades 30b enter between the most advanced pachinko ball B ₁ and the next pachinko ball B ₂ as shown in FIGS. 6 (c) and 6 (d). The next pachinko ball B ₂ is supported by the circular arc upper surface 31 of the pachinko ball B ₂ , and the latest pachinko ball B ₁ is discharged into the discharge passage 23 along the circular arc guide portion 33 while being fed into the circular arc recess 32. . After that, a predetermined number of pachinko balls are paid out by repeating the same operation.

The leaf springs 34, 34 provided on the arc-shaped guide portions 33, 33 serve to prevent the arc-shaped guide portions 33, 33 from being worn, and the elastic force of the leaf springs 34, 34 causes the pachinko ball to move. Can be surely inserted into the arcuate concave portion 32 of the rotating body 27, and this serves to make the payout operation of the pachinko ball more accurate.

[0016]

As is apparent from the above description, the pachinko ball dispensing device of the present invention is arranged such that the pachinko ball next to the most advanced pachinko ball continuously waiting in the supply passage is the arc of the blade of the rotating body. Since the most advanced pachinko balls are delivered to the delivery passage while being received by the top surface, the ball biting phenomenon seen in conventional pachinko ball delivery devices using sprockets does not occur at all, and the pachinko balls are delivered one by one reliably. be able to. Further, the device of the present invention has a simple structure and is excellent in economic efficiency, and it can be used in a stable state with few failures.
