Description

TECHNICAL FIELD The present invention relates to a ball-slicing device that cuts a predetermined number of balls to be continuously discharged when a ball enters a hole of a pachinko machine.

(Prior Art) FIGS. 5 and 6 show a first comparative example of a ball-slicing device for a conventional pachinko machine, in which sprocket wheels 2 and 2'where a ball pedestals 1 and 1'are annularly arranged at a constant pitch are half-pitch. It is slid and fixed to the rotating shaft 4'of the motor 3, and when a ball enters a winning hole (not shown), the motor 3 is turned on and the sprockets 2 and 2'are rotated to alternate from both sprockets 2 and 2 '. The balls 4 are discharged to the discharge path 5, counted by the sensor 6, and the motor 3 is stopped when a predetermined number is reached.

FIG. 7 shows a second comparative example of the related art, in which a discharge solenoid 12 is provided at the tip of a discharge passage 11 of a ball 10 and a plurality of partition solenoids 13, 14, 15, 16 are arranged at predetermined intermediate discharge position numbers. Is turned on and the discharge port 11 is closed by the stopper 12 ', and the balls 10 are accumulated in the discharge path 11. When a ball enters a role hole (not shown), the partition solenoid 13 is operated according to the number of balls to be ejected, the ball 10 is partitioned by the stopper 13 ', and then the ejection solenoid 12 is turned on to make the stopper 1
2'is retracted and the discharge port 11 'is opened to discharge a predetermined number of balls.

FIG. 8 shows a third comparative example of the related art. A partition arm 23 swinging around a fulcrum 22 is pivotally attached to the side of the discharge path 21 of the ball 20, and the end of the arm 23 is bent to form a stopper 24. , The stopper 25 is detachably attached to the rear part, and the attachment position is made variable by the number of balls to be ejected, and the spring 23 constantly rotates the arm 23 in the direction of arrow A so that the stopper 24 closes the outlet 21 'and the stopper 25 ejects It is designed to be retracted from the road 21. Therefore, the balls 20 are accumulated in the discharge path 21 above the stopper 25. When a ball enters a role hole (not shown), the solenoid 27 is turned on and the arm 23 is rotated in the direction of arrow B to partition the ball 20 in the discharge path 21 with the stopper 25 and at the same time retract the stopper 24 to discharge the ball. 21 'is opened and a predetermined number of balls are discharged.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the first comparative example causes a deviation in the number of balls output due to the accumulated error of the stop position due to the rotational inertia of the motor, and the motor is used. There was a problem that it could not be realized. Further, in the second and third comparative examples, there was a problem that the position of the stopper was changed and the number of solenoids was increased in order to change the number of balls, so that the structure was complicated and the size became large and expensive.

(Means for Solving Problems) The present invention is intended to solve the above problems, and a plurality of protrusions are formed on both sides of the outer periphery at the same pitch, and a coil is wound around a ring groove in the middle of the outer periphery. A rotor is rotatably and concentrically arranged on the outside of the child, and a large number of protrusions are formed on the inner circumference of the rotor so as to face the protrusions of the stator.The stator and the rotor are made of a magnetic material, and balls are formed on the outer circumference of the rotor. The pedestal is formed with the same pitch as the above-mentioned projections, and a ball discharge path is formed on the outside of the rotor.When the coil is energized, the rotor projection is attracted to the stator projection and the rotor is stopped. Is energized to make the rotor rotatable, and the weight of the balls placed on the ball receiving base causes the rotor to rotate to discharge the balls.

(Example) Hereinafter, it demonstrates concretely based on the Example shown in figure.

1 to 3 show the first embodiment. Reference numeral 31 denotes a cylindrical stator having a large number of protrusions 31a and 31a 'formed on both outer circumferences at the same pitch, entirely made of a magnetic material, and a coil 33 wound around a ring groove 31b in the outer peripheral middle portion. 34 is the stator 3
1 a rotor disposed outside, rotatably supported by bearings 36a, 36a 'disposed on the outer periphery of boss portions 35a, 35a' integrally fixed on both sides of the stator 31, and the stator 3
The projections 34a, 34 facing the projections 31a, 31a '
The whole a'is formed of a magnetic material. On the outer periphery of the rotor 34, ball receiving pedestals 37a and 37a 'are arranged side by side with the same pitch shifted by a half pitch, a guide 38 is fixed on the outer side thereof, and a ball discharging path 39 is provided at a predetermined position of the guide 38,
A sensor 41 is provided at a position where 0 falls into the discharge path 39.

Next, the operation will be described. The coil 33 is energized simultaneously with the pachinko machine operation. A closed magnetic circuit is formed between the rotor 34 and the stator 31, and the protrusions 34 a, 34 of the rotor 34 are formed.
The a'is attracted by the protrusions 31a, 31a 'of the facing stator 31 and the rotor 34 is stopped. When a ball enters the working hole, the coil 33 is de-energized and the magnetic flux in the closed magnetic circuit disappears, so that the rotor 34 becomes rotatable and the ball pedestals 37a, 37 are provided.
The balls 40 placed on a'are rotated by the weight of the balls 40, and fall on the discharge path 39 alternately from the two ball pedestals 37a, 37a 'every half pitch 34 rotations. The number of balls falling is counted by the sensor 41, and when the number reaches a prescribed number, the coil 33 is energized to form the closed magnetic circuit, and the protrusions 34a, 34 of the rotor 34 are formed.
a'is instantaneously the magnetic flux in the closed magnetic circuit, and the protrusion 31a of the stator 31
31a 'is sucked and stopped, and the discharging of the balls is stopped.

FIG. 4 shows a second embodiment, in which 50 is a stator, 51 is a rotor, and a coil 52 is arranged on the rotor 51. The operation is the same as in the first embodiment.

(Effect) According to the present invention, a large number of protrusions are formed on both sides of the outer periphery at the same pitch, and the rotor is rotatably and concentrically arranged on the outside of the stator in which a coil is wound in a ring groove in the middle of the outer periphery. A large number of protrusions are formed on the inner periphery facing the protrusions of the stator, the stator and rotor are made of a magnetic material, and a ball pedestal is formed on the outer periphery of the rotor at the same pitch as the protrusions. A discharge path is formed, and when the coil is energized, the protrusion of the rotor is attracted to the protrusion of the stator to stop the rotor, and the coil is energized by the ball ejection signal to allow the rotor to rotate and to be placed on the ball receiving stand. Since the rotor is rotated by the weight of the ball that is ejected to eject the ball, the rotation of the rotor is magnetically controlled by turning the coil on and off, and the rotor is rotated by the weight of the ball, so the structure is simple. Can be miniaturized, rotor inertia It is possible to stop instantly and there is no rotation stop position error, so there is no error in the ball throwing machine, and the number of ejected pachinko balls can be changed simply by changing the count completion value of the counting sensor.
