[0003]

The conventional ball dispensing apparatus for a pachinko machine has the following problems because it has been configured as described above. That is, when a ball is supplied, a large force is applied, and the motor may run idle and release the ball. For this reason, a large motor, a reduction mechanism such as a worm gear, a latch mechanism, and the like are required. Has been complicated and cost has been increased. In addition, the dispensing of the balls required about 20 pieces / second, causing wear and biting of the balls due to long-term use.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and in particular, a method and an apparatus for dispensing a ball of a pachinko machine which has been downsized with a simple structure using a guide cylinder and a cylindrical cam. The purpose is to provide.

[0005]

A ball dispensing method for a pachinko machine according to the present invention dispenses a ball falling under its own weight through an inclined guide tube in a guide tube by a cylindrical cam rotating at a lower portion of the guide tube. In the ball dispensing method for a pachinko machine as described above, the ball is formed spirally on the upper part of the cylindrical cam and descends via the cam lead for one ball, and is axially moved to the start point and the end point of the cam lead. The ball is dispensed in the horizontal direction perpendicular to the axial direction by the formed vertical end surface.The ball dispensing device of the pachinko machine according to the present invention is configured such that the ball falls by its own weight in the guide cylinder via the inclined guide cylinder. A ball dispensing device of a pachinko machine in which a ball to be dispensed is discharged by a cylindrical cam rotating at a lower portion of the guide cylinder.
Individual cam leads, a vertical end face formed in the axial direction at the start point and the end point of the cam lead, a dispensing slit formed at the lower part of the guide cylinder, and a motor for rotating the cylindrical cam. Wherein the ball is lowered via the cam lead and is discharged by the end face in a horizontal direction orthogonal to the axial direction, and the guide cylinder comprises at least two guide cylinders. The cam lead of the cam is configured to pay out balls in a horizontal direction one by one every half rotation, and the cylindrical cam is attached to a rotating shaft provided on a bearing protruding from the surface of the motor,
The lower end of the cylindrical cam is in contact with the surface of the bearing.

[0006]

In the method and apparatus for dispensing balls of a pachinko machine according to the present invention, the balls falling in the guide cylinder by their own weight are:
The cylindrical cam is rotatably provided at a lower portion of the guide cylinder and abuts against a cam lead for one ball of the cylindrical cam. When the cylindrical cam is rotated, the ball is horizontally moved by a vertical end face of the cylindrical cam. Will be paid out. Further, since the cam lead of this cylindrical cam is equivalent to one ball, two balls are paid out for one rotation of the cylindrical cam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a cylindrical cam which constitutes a ball dispensing means, and a spiral cam lead 3 for one ball 2 is formed on the upper part of the cylindrical cam 1 in a spiral plane. Is provided.

A vertical end face 3a is formed at the starting point and the ending point of the cam lead 3, and first and second guide cylinders 4, 5 for guiding the ball 2 are provided above the cylindrical cam 1. ing. Each of the guide cylinders 4 and 5 has a first and a second inclined guide body 4.
A and 5A are connected, and two to three of the number of balls 2 guided in each of the guide cylinders 4 and 5 are placed on the cam lead 3 by its own weight. Each of the inclined guides 4
The ball 2 in A, 5A is configured to be inclined and fall into each of the guide tubes 4, 5 by its own weight, and the ball 2 is configured to descend through the spiral cam lead 3. ing.

Next, as shown in FIG. 1 to FIG. 4, first and second slits 10 and 11 formed along the axial direction are provided below the guide cylinders 4 and 5, respectively. 1
The first and second payout slits 12 facing 0 and 11;
13 are formed. The guide tubes 4 and 5 are configured to be guided into the slits 10 and 11 and the payout slits 12 and 13.

The cylindrical cam 1 is driven by a motor 20 composed of a small step motor to rotate in the direction of arrow A. The weight of the ball 2 is equal to that of the cylindrical cam 1 and the motor 2.
Since the ball 2 is received in the axial direction of 0 (particularly a bearing 20a such as a metal bearing) and the ball 2 is dispensed in a horizontal direction perpendicular to the axial direction, the motor 20 is hardly loaded.

Since the guide cylinders 4 and 5 and the inclined guide bodies 4A and 5A are divided, the shock resistance at the time of initial ball replenishment is strong, and the well-known holding torque when the step motor is not energized is used. The idling of the motor 20 can be prevented. A bearing 20a protrudes from a surface 20B of the motor 20, and a lower end 1a of the cylindrical cam 1 provided on a rotating shaft (not shown) in the bearing 20a abuts on a surface 20Aa of the bearing 20a. Therefore, the impact when the ball 2 falls on the cylindrical cam 1 is applied to the bearing 20a and does not hit the rotary shaft, so that damage to the rotary shaft can be prevented. Therefore, it is possible to prevent the motor 20 from being damaged by an impact when the ball 2 is guided by the cylindrical cam 1.

Next, the operation will be described. First, as shown in FIG. 2, when the motor 20 is rotated in the state of A, the cylindrical cam 1 rotates in the direction of arrow A, and the second guide cylinder 5 is rotated.
The ball 2 is dispensed from the second dispensing slit 13. B,
In the state C, the ball 2 abuts on the cam lead 3, and in the state D, the ball 2 passes through the first payout slit 12 of the first guide cylinder 4.
Pay out. Therefore, by using the cam lead 3 for one ball 2, two balls 2 can be paid out by one rotation of the cylindrical cam 1. The number of the guide cylinders 4 and 5 is not limited to two, but may be one or two or more.

In addition, in the configuration of the type actually used as shown in FIGS. 4 to 6, the cylindrical cam is provided with a flange 30 having a function of a ball dispensing guide fin and a photocoupler disk. The guide tube 4,
The cylindrical cam 1 is guided by engagement with a photodetector 32 provided on a main body 31 that holds the cylindrical member 5 so that the number of rotations of the cylindrical cam 1 can be detected to detect the number of balls 2 paid out.

[0014]

The ball dispensing method and apparatus for a pachinko machine according to the present invention are configured as described above, so that the following effects can be obtained. In other words, the configuration is simple and inexpensive because the ball is paid out by the guide tube that guides the ball and the cylindrical cam that engages with the guide tube. Further, since only a few balls are guided in the inexpensive cylinder, the load on the cylindrical cam and the motor can be minimized, and high reliability without ball erroneous delivery can be obtained.
