Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball dispensing device for a pachinko machine, and more particularly to a ball dispensing device for a pachinko machine which dispenses a pachinko ball by rotating a lead screw.

[0002]

2. Description of the Related Art Conventionally, as a ball payout device for a pachinko machine, for example, as shown in FIG. 8, a plurality of pachinko ball supply passages 101 and each supply passage 101 are provided so that a part of their outer periphery faces. Further, a plurality of sprockets 103 each having a concave claw portion 102 into which one pachinko ball can be fitted and having their phases shifted by a predetermined angle, a drive motor 104 for rotating each of the sprockets 103, and a discharge end of each of the sprockets 103 are provided. Sphere detector 1 for each part
No. 06 is provided, and each sprocket 103 is rotated by the drive motor 104 to discharge a predetermined number of pachinko balls to the discharge passage 105, and each ball detector 106 detects the pachinko balls to control the number of payouts. It is known that In addition, there is also one in which the number of payouts is controlled by detecting the number of rotations of the sprocket.

[0003]

However, when detecting the pachinko balls in the plural supply passages 101 as in the former case, the pachinko balls in the preceding passages are detected and then the pachinko balls in the other passages subsequent thereto are detected. The number of angles (time) required to detect is reduced. Therefore, for example, when ejecting 10 pachinko balls to be paid out at one time, the number of angles for ejecting the 9th to 10th pachinko balls is small, and thus the inertia is 11
There is a risk that the second pachinko ball will be excessively discharged. Then, since the stop position is extremely limited, the rotation speed must be slow. In addition, the drive motor 10
Since the movable position and the stop position of No. 4 are remarkably limited and repeated in small steps, there is a problem that an excessive load is applied to the drive motor 104. On the other hand, the concave claw portion 10 of the sprocket 103 is improved in order to improve the small movement and the stop.
A measure was taken to reduce the number of 2 to a small number, but in this case, the distance between the claws 102 becomes long, but the pachinko ball remains in the non-moving state during this time, and the sprocket 103 is wasted in ball pressure and frictional resistance. However, since the rotation direction peculiar to the sprocket 103 and the movement direction of the pachinko ball are the same, it has not been possible to improve the load on the drive motor 104 itself. By the way, if the sprocket 103, pachinko ball, etc. are contaminated with dirt,
The resistance of the pachinko ball in the non-migrating state will be further increased.

As can be seen from the above, the pachinko balls are in a non-moving state between the pawls 102 provided to widen the detection intervals of the pachinko balls, so that a useless load or resistance is applied to the drive motor 104. Even if the sprocket-type ball dispensing device has a single supply passage, the pachinko balls are excessively dispensed and the durability of the drive motor is impaired. Further, in order to improve these, a device for electrically controlling the device is required to be large in size, for example, a drive motor is to be increased in size, which requires additional labor and cost.

The latter method is a method in which the pachinko balls are not actually detected individually. Therefore, not only the problem that the detection error may occur such as the insufficient or excessive pachinko balls being paid out occurs, but also the former case. These challenges were inherited as they were.

Therefore, the present invention has been made to solve the above-mentioned problems, and an excessive load is not applied to the drive motor, the payout can be performed very smoothly, and the pachinko ball can be detected smoothly and accurately. The object is to provide a ball dispensing device for a pachinko machine.

It is an E-ring for preventing the removal of 3. And the switch 3
7, the ball payout device 13, and the passage switching device 30 are electrically connected to each other.

The pachinko machine 1 of the present invention is constructed as described above, and its operation will be described below. When the winning ball guided to the winning ball passage 5 is detected by the winning ball detector 6, the drive motor 16 of the ball payout device 13 is rotated by the detection signal, and the lead screw is passed through the driving gear 26 and the driven gear 27. Rotate 17. The rotation of the lead screw 17 causes the pachinko balls that are continuously waiting in the supply passages 19a and 19b to descend as the ball transfer strut 22 moves, and when the lead screw 17 makes one rotation, the ball transfer strut 2
The state-of-the-art pachinko ball supported by 2 is the ball transfer strip 2
It is removed from the support of No. 2 and is discharged to the discharge passages 20a and 20b.

In order to remove the pachinko ball from the ball tank 10, the pin hole 48 of the front frame 47a from the front side of the pachinko machine 1 is removed.

By turning on 7, the drive motor 16 of the ball dispensing device 13 is rotated, the passage switching device 30 is operated, and the switching lever 32 is rotated as shown by the chain line in FIG. As a result, the switching lever 32 connects the discharge passage 20 and the ball removal passage 29 to guide the pachinko ball dispensed from the ball dispensing device 13 to the ball removal passage 29 to remove the ball. When the ball removal is completed, the ball removal solenoid 31 of the passage switching device 30 is demagnetized, the switching lever 32 returns to the original state, and the ball removal passage 29 is closed.

As described above, in the ball payout device of the pachinko machine according to the present invention, the ball pressure of the pachinko ball in the supply passages 19a and 19b is applied in the direction of the rotary shaft 23 of the lead screw 17, so that the conventional sprocket system is used. As compared with the ball dispensing device described above, the drive motor 16 is not overloaded, and the lead screw 17 can be smoothly rotated. By arranging the ball detectors 28a and 28b at or near the terminal end of the lead screw 17, the detection interval between the previous pachinko ball supported by the ball transfer strip 22 and the subsequent pachinko ball is widened. Further, since the subsequent pachinko ball is placed at the discharge position while moving, the driving motor 16 does not need to be moved or stopped little by little, unnecessary load is not applied, and the pachinko ball can be discharged smoothly and accurately. It becomes possible to detect.

In addition, as in the present embodiment, the two supply passages 1 are provided.
When 9a and 19b are provided, as shown in FIG. 5, the sphere detectors 28a and 28b are located at positions where the outer circumference of the lead screw 17 is approximately equally divided, and in the present embodiment, about 180 degrees positions with the rotary shaft 23 interposed therebetween. If the pachinko balls are provided at different positions, the detection interval between the pachinko ball ahead of which the ball transfer strip 22 loses its support and the subsequent pachinko ball is sufficiently widened, so that the pachinko balls can be smoothly dispensed. In addition, accurate detection is possible, and the load on the drive motor 16 is also reduced. Although illustration is omitted, when the supply passages are three-row, they may be separated from each other by about 120 degrees, and when they are four-row, they may be separated by about 90 degrees.

Further, according to the present invention, the sprocket does not project into the supply passage in the shape of an arc unlike the sprocket type ball dispensing device, but the supply passages 19a and 19b are made to face each other in parallel, and the lead screw is used. Since the end portion of 17 has a shape that is well cut off on the downstream side, it is not limited to the positions and types of the sphere detectors 28a and 28b.

[0023]

As described above, in the ball payout device of the pachinko machine according to the present invention, the lead screw is arranged in parallel with the supply passage, and the lead screw has a spiral shape facing the inside of the supply passage. It is configured by providing the ball transfer strip of
A ball detector for detecting a pachinko ball in the supply passage is provided at or near the end of the lead screw, and the pachinko ball in the supply passage is ejected and detected by the rotation of the lead screw. The detection interval with the ball can be widened, and the subsequent pachinko ball is sent to the ejection position (detection position) while moving in parallel to the axial direction, and the drive motor is excessively movable like a sprocket and excessively large. Since no heavy load is applied, it is not necessary to move or stop in small increments unlike the sprocket type ball dispensing device. Therefore, the lead screw rotates smoothly,
It enables smooth pachinko ball payout and accurate detection of pachinko balls. In addition, since the drive motor is not overloaded, a small motor can be used, the device for controlling these electric devices does not become large, and the cost can be reduced.

Further, in the case where there are a plurality of supply passages, if the respective ball detectors are provided at positions that are approximately equally divided on the outer circumference of the lead screw, a detection interval between the previous pachinko ball and the subsequent pachinko ball is required. Since the pachinko ball is sufficiently widened, the accuracy of detecting the pachinko ball is not impaired, and an excessive load on the drive motor can be avoided, which enables cost reduction as in the above case.
