[0007]
As described above, the pachinko ball discharge device 4 is interposed between the pachinko ball lead-out rod 3 and the pachinko ball discharge rod 5, and both balls 3, 3 are formed by the ball passage 9 formed between the two plates 8 f and 8 r. Tie five. The ball passage 9 is divided into an entrance passage 9a, a ball cutting passage 9b, and a discharge passage 9c from the top. The entrance passage 9a is divided into two rows via a central partition plate 9d, and has proximity switches 10 and 10 for detecting pachinko balls on the side surface. On the other hand, as shown in FIG. 2, the lower discharge passage 9c is a passage in which a single pachinko ball can pass and is arranged in the center of the plates 8f and 8r. The guide piece 14 is provided in a funnel shape from the plates 8f and 8r toward the passage switch 11.
[0008]
A ball control rotating body 12 is provided in a ball cutting passage 9 b located in the middle of the ball passage 9. The ball control rotator 12 is formed by projecting two sets of claw wheels R1 and R2 on the outer periphery of a round bar-shaped body 12a, and each claw wheel R1 and R2 corresponds to two rows of inlet passages 9a. The two sets of claw wheels R1 and R2 are each composed of three engagement claws 12b, 12b and 12b. As shown in FIG. 4, each of the claw wheels R1, R2 is set so that the angle between the engagement claws 12b, 12b... Is shifted by 60 degrees, and the engagement claw 12b of one claw wheel R1 is Y-shaped. In this state, the engaging claw 12b of the other claw wheel R2 is in an inverted Y-shape. Therefore, in the initial state in which the pachinko balls are supplied, one pawl wheel R1 receives the pachinko ball B1 between the back and the abdomen of the engaging claws 12b and 12b as shown in FIG. 3, and the other pawl wheel R2 is shown in FIG. Thus, the pachinko ball is received by a ball stopper 12c described later on the top of the engaging claw 12b.
[0009]
Each of the engaging claws 12b, 12b... Has a concave arc shape that fits the spherical surface of the push-out side (abdominal side) of the pachinko sphere, and a convex arc shape on the opposite back side. An arc-shaped ball stopper 12c centering on the rotation center of the claw wheels R1, R2 is provided, and the height thereof is set lower than that of the pachinko ball.
[0010]
As shown in FIGS. 2 to 4, the ball control rotator 12 is disposed immediately below the center of the inlet passage 9 a. The body 12a of the ball control rotator 12 is fixed to a rotating shaft 13a of a stepping motor 13 installed on the plate 8f, and the sphere control rotator 12 is driven by the stepping motor 13 as shown in FIGS. Rotate counterclockwise at.
[0011]
Next, the discharge operation of the pachinko ball discharge device 4 will be described first from the claw wheel R1 on the plate 8r side of the ball control rotor 12. As shown by the solid line in FIG. 3, in a state where the claw wheel R1 is stopped in a Y shape, the pachinko ball B1 stops between the back and the abdomen of the upper two engaging claws 12b and 12b, and this pachinko ball Since the center of gravity of B1 is on a straight line passing through the center of the rotation shaft 13a, the ball pressure acts toward the rotation center of the ball control rotating body 12.
[0012]
In this state, when the stepping motor 13 is operated and the ball control rotating body 12 is rotated 60 degrees counterclockwise in FIG. 3, the pachinko ball B1 is placed on the back of the engaging claw 12b as shown in FIG. It stops in the middle of the ball cutting passage 9b. At this time, the pachinko sphere B2 on the pachinko sphere B1 is received on the ball stopper 12c of the engaging claw 12b as shown by a one-dot chain line in FIG. In this state, the ball pressure of the upper pachinko sphere including the pachinko ball B2 is applied to the ball stopper 12c. However, since the ball stopper 12c has an arc shape centered on the rotation center of the claw wheel R1, the ball pressure is rotated. Heading to the center of the shaft 13a. Accordingly, the ball pressure of the pachinko sphere is hardly resistant to the rotation of the ball control rotor 12.
[0013]
Then, when the ball control rotator 12 is further rotated by 60 degrees from the state of the one-dot chain line in FIG. 3, the pachinko ball B1 comes out of the ball cutting passage 9b, is guided by the guide piece 14, and falls to the center of the discharge passage 9c. Subsequently, it is detected by the passage switch 11 and released to the pachinko ball discharge basket 5. At this time, the pachinko ball B2 on the pachinko ball B1 is received between the engaging claw 12b and the engaging claw 12b and is waiting.
[0014]
Next, as described above, when the pawl wheel R1 on the plate 8r side is in the Y-shape in FIG. 3, the pawl wheel R2 on the plate 8f side is in the inverted Y-shape as shown in FIG. The ball B3 is received by the ball stopper 12c of the engaging claw 12b. When the ball control rotator 12 rotates 60 degrees, the ratchet wheel R2 becomes Y-shaped, and the pachinko ball B3 is held between the back and the abdomen of the upper two engaging claws 12b and 12b to perform the next rotation. wait. Next, when the ball control rotator 12 rotates 60 degrees, the pachinko ball B3 waits in the ball cutting passage 9b as in the case of the ratchet wheel R1, and when the sphere control rotator 12 rotates 60 degrees, it is discharged into the discharge passage 9c. Is done.
[0015]
Thereafter, every time the ball control rotator 12 rotates 60 degrees, one pachinko ball is alternately released from each of the ratchet wheels R1 and R2. The rotating body 12 may be rotated (2 + 1/2). Similarly, for the seven winning signals, the ball control rotating body 12 is rotated (1 + 1/6), and 25 ball lending commands are received from the ball lending apparatus 18 as shown in FIG. In this case, the sphere control rotator 12 may be rotated (4 + 1/6).
[0016]
As shown in the illustrated embodiment, an even number of sets of claw wheels R1 and R2 are provided, a Y-shaped state for receiving pachinko balls at the back and abdomen of the engaging claws 12b and 12b, and pachinko balls at the ball stoppers 12c of the engaging claws 12b. If the reverse Y-shaped state for receiving is set to repeat alternately, the stop position of the ball control rotating body 12 is always automatically corrected. That is, the ratchet wheel R1 (R2) is most stable when it is in the Y-shape as shown by the solid line in FIG. 3 and is subjected to the ball pressure in the recess between the back and the abdomen of the engaging claws 12b and 12b. On the other hand, at this time, the other ratchet wheel R2 (R1) is in a state in which the pachinko ball is received by the ball stopper 12c of the engaging claw 12b, so that it can rotate even with a light force without receiving any resistance of the ball pressure. Therefore, even if the stop position of the ball control rotating body 12 is not constant, the Y-shaped side wheel R1, R2 is returned to a stable position by the action of the ball pressure. The stop position is always automatically corrected.
[0017]
【The invention's effect】
The pachinko ball discharge device of the present invention automatically corrects to a well-balanced angle because a ball pressure is applied between the back and abdomen of the engaging claws of at least one ratchet wheel even if the ball control rotor rotates slightly. Is done. In this state, the adjacent pawl wheel stops the pachinko ball with a single engaging pawl, so that the ball stopping action by the engaging pawl is stabilized by correcting the angle of the ball control rotating body.
