Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball firing device, and more particularly to a ball firing device that is an improved ball firing device for hitting a ball onto a board in an electric pachinko machine. It is.

[Conventional technology] In recent years, the ball device for pachinko machines has changed from a manual system to an electric system, but the basic principle of the ball device, which uses a ball hammer to hit the ball onto the board, is the same as the ball device of the manual system era. This conventional ball device is not changed in the slightest from the ball device.This conventional ball device will be explained with reference to FIGS. 5 to 10.

FIG. 5 is a perspective view showing an example of a conventionally used electric ball device.

This ball device includes an operating handle 10 and a ball motor 11 that starts upward rotation by operating the operating handle 10.
The guide rail 1 is rotated by the rotation of the ball motor 11.
2. A batting mallet 15 for bouncing the ball 14 located in the special ball batting unit 13 at the lowest end, and an adjustment spring 16 for changing the bouncing force of the batting mallet 15 by operating the operating handle IO.
It is formed from. Further, the rotation speed of the ball motor is controlled in order to comply with legal regulations that prohibit the ball from firing more than 100 balls per minute.

FIG. 6 is a sectional view showing the operating handle 10, FIG. 7 is a sectional view showing the ball motor 11 and the ball hitting mallet 15, and FIG. 8 is a front view showing the positional relationship between the guide rail 12 and the tip of the ball hitting mallet 15. , FIG. 9 is a cross-sectional view of the same, and FIG. 10 is a ball 14 that has been hit.
FIG. 3 is a front view for explaining a state in which the vehicle is ascending on the guide rail lz.

The conventional ball device will be explained in more detail with reference to these drawings.

The operating handle 10 is rotatably fixed to a front frame 18 below the panel surface 17, and an adjustment pulley 19 that rotates at the same time as the operating handle 10 is fixed to the back side of the front frame 18 of the operating handle 10.

Further, this m11 pulley 19 is fixed to one end of a lever rod 21 by a connecting wire 20, and the other end of this lever rod 21 is connected to an adjusting rod 22. It is connected to the ball hammer 15 via a W adjustment spring 16. Therefore, when the operation handle 10 is rotated, the ball motor 11 starts rotating, and the adjustment pulley 19 is rotated depending on the rotation angle of the operation handle 10. This rotation causes the connection wire 2
The lever lever 21 is oscillated through the 0, and the adjustment spring 16 is pulled by this oscillation, and as a result, the ball hitting mallet 15 is pressed against the special ball hitting unit 13, so that the force of the ball is strengthened.

The batting mallet 15 is pivotally supported by a front frame 18 so as to be able to swing freely, and is connected to the above-mentioned adjustment spring 16, and has a ball spring 23 at the tip on the batting standby i13 side.
is fixed. Furthermore, a ball stay 25 having a roller 24 pivotally supported at its tip is fixed to the ball hammer 15.

Although this batting mallet 15 is fixed to the front frame 18,
The guide rail 12 constituting the special ball hitting section 13 is fixed to the board surface 17 forming the game surface. In addition, the ball mallet 15 is made of rubber so that it stops instantaneously after the ball is hit.
The par is 26.

The ball motor 11 has a drive cam 28 fixed to its output shaft 27, and the rotation of the ball motor 11 also rotates the drive cam 2B, and the drive cam 28 adjusts the ball stay 25 of the ball hammer 15. It is made to oscillate toward the counter-hitting ball special unit 13 side against the elastic force of the spring 16. Therefore, this drive cam 28 and the roller 2 of the ball stay 25
4 is released, the ball hitting mallet 15 swings toward the special ball hitting unit 13 side by the elastic force of the adjustment spring 16, and this swinging causes the ball spring 23 to move the ball 14 of the special ball hitting unit 13.
is launched onto the board 17.

In addition, FIG. 8 shows the ball 14 and the ball spring 2 of the batting mallet 15.
The ball 14 is transferred on the guide rail 12 by the ball spring 23, and when it slips on the guide rail 12, it hits the board surface 17.
This means that the point at which it falls is not constant. Therefore, it is desirable to ascend while rotating on the guide rail 12 at a rotation speed that matches the traveling speed. Therefore, normally the ball spring 23 is positioned slightly above the center of the ball 14 so that one ball can move upward. The ball 14 is given forward rotation so that it rises while rotating on the guide rail 12. FIG. 1θ shows such rotational rise of the ball 14.

FIG. 9 also shows the ball 14 and the ball spring 2 of the batting mallet 15.
The ball 14, which is hit by the ball spring 23, is located on the board surface 1.
If the ball is hit either toward the 7 side or the glass side, it will cause damage to the pachinko machine.Therefore, the point of the ball 14 had to be aligned with the vertical line of the ball 14.

[Problems to be Solved by the Invention] In such a conventional ball device, the ball spring 23 of the ball mallet and the ball 14 of the special ball hitting unit 13 at the bottom of the guide rail 12
Unless the position is ideal, the positions of the balls 14 falling onto the board surface 17 will be different, and especially if the positional relationship is significantly different, damage to the board surface 17 or the glass may be caused.

These causes are due to the ball spring 23 of the ball batting mallet 15 and the ball hitting special part of the guide rail 12 in order to fix the rail to the board surface 17, although the ball batting mallet 15 is pivotally supported on the front bench lB. This is due to the fact that it is difficult to delicately adjust the positional relationship between ball 14 and ball 13.

Furthermore, in pachinko machines, the existence of so-called slumps makes the game more interesting. That is.

Even when hitting similar balls, there are times when the number of winnings per unit time is high and times when the number of wins is low, and this makes it possible to play games based on skill and luck.

Therefore, in order to eliminate the drawbacks of the prior art, the present invention does not use the conventional ball system, but instead forms the ball so that it rotates and rises from the beginning, and also uses the same member as the guide rail. By fixing the ball launcher to the board surface, alignment is not required, and by using two launch rollers, a slump can be prevented by mechanically forming a slit between the rail and the roller. This makes the game itself more interesting.

[Means for solving problems].

In order to solve the above-mentioned problems, the present invention includes two rollers that rotate in conjunction with a firing motor according to the amount of operation of the operating handle, and a ball that is positioned between the outer periphery of these two rollers. It is characterized by having a guide rail for guiding the ball between the outer peripheries of the rollers in order to shoot it onto the board surface, and a guide rail that sends out the shot ball to the board surface by the rotation of the two rollers.

[Example 1 An embodiment of the present invention will be described below along with illustrated examples.

FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG.
3 is a perspective view of the operating handle 10, and FIG. 4 is a pulse diagram for changing the firing speed.

Explaining with reference to each of these illustrated examples, the ball firing device according to the present invention includes an upper roller 13 and a lower roller 14, which are a pair of rollers 13.14 that rotate in conjunction with two firing motors 11.12. And these two rollers 13.
a guide rail 16 for guiding the ball 15 between the outer peripheries of the ball 14;
It is formed of a guide rail 17 for causing the ball 15 launched by both rollers 13 and 14 to be launched onto a board surface (not shown).

The firing motor 11.12 rotates both the upper roller 13 and the lower roller 14 so that the rotational speed of the upper roller 13 and the lower roller 14 can be changed.
3.14 It is formed from an upper firing motor 11 and a lower firing motor 12 fixed to each. In addition, both the firing motors 11 and 12 are connected to the ball 15 thrown into the guide rail 16.
It is fixed to the board surface in order to fire it onto the board surface, and starts rotating when the operating handle 10 is rotated, and the number of rotations increases as the rotation angle of the operating handle 10 is increased. As such means, for example, a motor drive amplifier and a rotation speed adjustment volume are provided in a motor drive circuit that is linked to each of the upper roller 13 and the lower roller 14, and the adjustment of the rotation speed adjustment volume is controlled by an operation handle. It is possible to vary the rotational speed of the firing motor 11.12 by doing so by 10 rotations. At this time, for example, if the waveform shown in Fig. 4 is applied to the firing motors 11 and 12, the firing motors 11 and 12 will rotate at a low speed in the waveform (A) and at a medium speed in the waveform (B). , (C) results in high-speed rotation. Therefore, (A), (B)
, (C), the ball 15 will fly further away.

Further, both rollers 13 and 14 are positioned so as to have a gap slightly narrower than the diameter of the ball 15, and are made of an elastic material, such as rubber.

Or it is made of plastic material etc.
Both firing motors11. X2 is fixed to each output shaft. Further, the upper roller l"3 is rotated to the right in the front view, and the lower roller 14 is rotated to the left.

The guide rail 16 is formed so as to gradually move away from between the rollers 13 and 14 in a direction opposite to the guide rail 17.

More specifically, the distance from the outer circumferential surface of the upper roller 13 near the upper end surface of the outer circumference of the lower roller 14 to the center of the upper roller 13 is gradually increased. It is formed similar to an involute curve or a spiral curve of the upper roller 13, so to speak.

The guide rail 17 is for guiding the ball 15 thrown into the guide rail 16 and fired by both rollers 13, 14 to the board surface.

Next, the operation of the ball launcher according to the present invention will be explained.

First, in order to facilitate understanding of the present invention, a ball 1 is inserted into the input section.
The charging device No. 5 will be explained.

In conventional pachinko machines, the ball 15 feeding device is linked to the operation of the firing lever, but the ball 15 feeding device used in the present invention is operated by rotating the operating handle IO, although illustration and detailed explanation are omitted. Rotating firing motor 11.1
Regardless of the rotation of the ball 2, each ball 15 is sent onto the guide rail 16 at a rate of 100 shots per minute by a ball 15 feeding device using a constant speed motor or a constant pulse generator.

The ball 15 thus sent out onto the guide rail 16 is sent out between both rollers 13 and 14 located at the lower part of the guide rail 16 by the gravity of the ball 15 itself.

Between the two rollers 13 and 14, the distance between the outer periphery of the upper roller 13 and the outer periphery of the lower roller 14 is formed to be slightly narrower than the diameter of the ball 15, so the ball 15 is sandwiched between both the rollers 13 and 14, and A rotational force is applied by both rotating rollers 13,14. Therefore, one ball 15 is sent out while rotating from between both rollers 13 and 14 to the guide rail 17, and then reaches the board surface along the guide rail 17.

In the present invention, it is sufficient to simply electrically connect the operating handle 10 and both firing motors 11, 12.
The operation handle 10 is pivotally supported on the front frame, and the firing motor 11.
i2 can be fixed to the board. Therefore, since the guide rails 16 and 17 and the firing motors LL and 12 are both fixed to the board surface, their alignment can be easily and reliably performed.

Further, in the present invention, both rollers 1 are attached to the ball 15 to be fired.
3.14 applies rotational force, and the ball 15 rotates the guide rail 17 at a speed corresponding to the number of rotations and ascends to the board surface, so there is no slippage between the guide rail 17 and the ball 15, and the ball 15 is always stable. This allows the ball 15 to be fired.

On the other hand, if the rotation speeds of the two firing motors 11 and 12 are set to be different, the ball 15 will slip when ascending the guide rail 17, and may not fall to the specified position, or may be different after colliding with the ceiling nail. The other side may be repelled in the opposite direction. Therefore, for example, if the rotational speeds of the upper firing motor 11 and the lower firing motor 12 are made different every time a certain period of time elapses, a so-called slump can be formed due to the change in the rotational speed.

Furthermore, in the present invention, the strength of the ejection of the ball 15 can be determined by simply changing the rotational speed of the re-ejection motors 1 and 12, so it can be achieved by extremely simple electrical processing without using springs or the like as in the past. It is possible to reliably change the firing strength.

In addition, in consideration of slight differences in diameter or distortion of the ball 15, both rollers 13 and 14 may be biased toward each other by springs or the like, or at least one roller may be made of an elastic material. It is also possible to

Further, the positions of both rollers 13 and 14 may be such that the centers of rotation are parallel to each other in the vertical direction, as shown in the illustrated example, but they do not necessarily need to be located in the vertical direction.

Although we have explained the case where two firing motors 11 and 12 are used, only one is used, and normally both rollers are used.
If the rollers 3.14 are formed to rotate at the same rate and the number of rotations is changed, it is sufficient to apply a load to one of the rollers.

[Effects of the Invention] As explained above, one aspect of the present invention is to form the ball so that it rotates and rises from the beginning so that the ball can be launched smoothly, and to install a ball launcher on the board surface which is the same member as the guide rail. By fixing the firing motor, there is no need to align the two, making assembly easier, and a slump is intentionally formed to improve gameplay.
