Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball launching device for circularly moving a pachinko ball along a wall inside a container by the rotational force of a rotary drive means such as a motor or a rotary solenoid, and firing the pachinko ball by its momentum. It is about.

[0002]

2. Description of the Related Art As a conventional pachinko ball launching device, a structure has been adopted in which a punch and a ball are continuously reciprocated by a combination of a motor and a cam, and each ball is hit by a repulsive force of the punch. The structure of this conventional pachinko ball launching device is illustrated in FIG.
It becomes like 8. A pestle 101 (made of urethane rubber or a coil spring) is attached to the tip of the arm 102.
02 is rotatable around the rotation shaft 106. Further, the arm 102 is strongly pulled by the pulling arm 107. The pulling force of the pulling arm 107 is supplied from the coil spring 108. The spring force of the coil spring 108 is adjusted by the player's hand with the handle 110 through the wire 109. Also, the arm 10
A cam receiving roller 105 is provided in the middle of 2,
The roller 105 is the rotating shaft 1 of the motor 113 with a reduction gear.
It is in contact with a cam 104 that rotates around 03.

The operation of the above structure is as follows.
When the cam 104 rotates about the rotating shaft 103, the movement is transmitted to the arm 102 through the roller 105 and is changed into a reciprocating movement. That is, the arm 102 is swung up until the cam 104 rotates to a certain angle, and when the roller 105 reaches a certain angle and disengages from the cam 104, the arm 102 instantly moves to the arrow A.
The punch 101 moves in the direction and hits the pachinko ball supplied from the communication hole 112 (described later). The shot ball is moved along the guide rail 111 and moves.
As is well known, it falls while hitting the nail hit on the gauge board (game board) when it is separated from.

The flight distance of the ball is the handle 110
Is adjusted by the player's hand. That is, the handle 1
When 10 is turned clockwise, the wire 109 is pulled, and the rotation angle of the coil spring 108 is changed through the wire 109, whereby the pulling arm 107 moves the arm 102.
The pulling force changes. If the coil spring 108 is strongly tightened, the force with which the punch 101 hits the ball is strong,
If the coil spring 108 is weakly tightened, the force with which the punch 101 hits the ball is weakened, so the flight distance is adjusted.

On the other hand, pachinko balls are supplied as follows. FIG. 19 is a structural diagram of an automatic ball feeder for pachinko balls. The automatic sphere supply device includes a saucer 124 for accumulating pachinko balls that have fallen in the purchase of rental balls or prize balls, and a saucer 124.
And a guide portion 126 for guiding the pachinko balls stored in the ball through the communication hole 125. Furthermore, the central axis 1
Pachinko ball supply arm 121 that rotates around 22
And the supply arm 121 is provided with a first claw 121a.
And the second claw 121b are integrally formed. The supply arm 121 is a connecting rod 1 connected to the motor 113.
23, and the connecting rod 123 reciprocates every time the motor 113 makes one rotation, and accordingly the supply arm 12
1 moves up and down. Along with the vertical movement of the supply arm 121, the pachinko ball passes over the first claw 121a and enters between the first claw 121a and the second claw 121b, and the first claw 121a and the second claw 121b The pachinko ball that has entered between the two passes over the second claw 121b and enters the communication hole 112. Then, the pachinko balls are supplied one by one through the communication hole 112 to the above-mentioned pachinko ball launching device provided on the back side.

[0006]

The pachinko ball launching device described above has a problem that a complicated mechanism is required and the size, particularly the depth, of the entire gaming machine becomes large. As a result, the number of units that can be installed in the limited island space decreases, and there is a demand from traders to reduce the island width.

When assembling the game machine device, first, the guide rail 111 is fixed to the launch pad, and then the communication hole 11 is formed.
The pachinko ball launching device was attached and fixed so that the center of the punch 101 just hits the pachinko ball dropped from No. 2, and the ball automatic feeder for the pachinko ball was aligned with the communication hole 112. In this mounting and assembling work, there is a problem that it is difficult to perform centering between the punch ball and the punch 101 (see the punch 101 drawn by the two-dot chain line in FIG. 18) and a skilled worker is required. If the centering cannot be done well (this is called "center misalignment"), the flying directions of the pachinko balls will be different, and the performance as a pachinko stand will be extremely reduced.

Further, since the punch 101 hits the ball with a force, it is necessary to increase the force of the coil spring 108, and the torque of the motor 113 to overcome the force must be increased. Therefore, the motor 113 becomes large. Moreover, since the number of revolutions is required to be accurate, an AC synchronous motor is required, and it is necessary to separately produce 50 Hz and 60 Hz. Further, the motor 113 needs a reduction gear.

Further, since the punch 101 vigorously hits the pachinko ball, a striking sound at the time of striking and static electricity are generated. In particular, since a lot of plastic is used for the pachinko stand, static electricity is accumulated in the plastic due to impact and vibration that strikes, which causes malfunctions in the electric system such as the integrated circuit controlling the gaming machine, which may cause failure. It is the cause.

Further, as the number of hits increases, the punch 1
The tip of 01 is deformed and consumed due to impact, and the bearing of the rotary shaft 106 is loosened or consumed, so that the above-mentioned misalignment and deviation of flight distance occur. Therefore, maintenance has been time-consuming, such as the need to replace the punch 101 and the like. Also,
In order to cope with the dimensional variation and wear of the pachinko ball launching device, the variation of tension of the coil spring 108 and the decrease over time, and the variation and looseness of the length of the wire 109, the tension of the coil spring 108 is adjusted and aligned. ,
The flight distance must be constantly adjusted.

Therefore, an object of the present invention is to solve the above-mentioned technical problem by eliminating the punching structure of the pachinko ball launching device, and to accurately launch the pachinko ball to a desired nail position on the gauge board surface. A ball-and-ball launcher that can manage the ball rate, can be downsized, does not require adjustment during installation and maintenance, suppresses the generation of static electricity, and can reduce the failure rate and improve reliability. Is to provide.

It can be thrown out from the ball hole. (2) In the pachinko ball launching device according to the second aspect, the ball pushing portion is composed of a rotating roller for smooth rolling of the pachinko ball. According to this, the pachinko ball can revolve while smoothly rolling on the inner wall. (3) In the pachinko ball launching device according to claim 3, the revolution radius a of the ball pushing portion is equal to (radius of circumference of inner wall of side surface)-(radius of pachinko ball) or slightly shorter than this. There is something. According to this, the pachinko ball revolves along the inner wall while being pressed toward the inner wall by the ball pushing portion. (4) In the pachinko ball launching device according to claim 4, a concave groove for guiding the pachinko ball along the circumferential direction is formed on the inner wall of the side surface. Therefore, the pachinko ball can be accurately guided along the concave groove. (5) The pachinko ball launching device according to claim 5 is provided with a rotation control device for controlling the rotation of the rotation driving means, and the rotation control device is such that the ball driving portion starts to push the pachinko ball from the rotation driving means.

[0016]

Embodiments will be described in detail below with reference to the accompanying drawings showing embodiments. FIG. 1 shows a front view of a rotary pachinko ball launching device according to an embodiment, and FIGS. 2 and 3 respectively show FIG.
II-II line sectional view, III-III line sectional view. The side wall inner wall 1c of the container 1 has a circumferential shape, and a pachinko ball ejection hole 1p is formed in a part of the inner wall 1c.

The container 1 has a bottom surface 1b as shown in FIG. 2 and is fixed to a launch pad. Automatic ball feeder (described later)
A panel 6 that separates the container 1 from the container 1 serves as a lid of the container 1. The exit of the ejection hole 1p is smoothly connected to the guide rail 7 fixed to the launch pad without any step. A motor 4 is arranged inside the container, and a rotation shaft 4p of the motor 4 is set concentrically with the circumference of the inner wall 1c. Motor 4
The type is not limited as long as it is a DC motor (for example, a hall motor, a spindle motor, a brushless motor), a stepping motor, or any other motor whose rotation speed can be freely controlled.

The rotating shaft 4p of the motor 4 is provided with a ball pushing roller 2 which revolves along the inner wall 1c in a non-contact state with the inner wall 1c via an arm 5. In addition,
The arm 5 is rod-shaped in FIG. 1, but is not limited to this. For example, a disc-shaped arm that also serves as a lid of the container 1 is provided with a boss portion for attaching a roller 2 and a hole for introducing a pachinko ball. May be installed upright.

The length a from the rotating shaft 4p to the center of the ball pushing roller 2 is equal to or slightly shorter than (radius of the inner wall 1c)-(radius of the ball) in order to prevent the ball from jumping. .. As shown in FIG.
As shown in, a groove 1d is formed along the circumference,
The sling ball is guided along the groove 1d. Therefore, even if the pachinko ball launching device tilts back and forth (in the direction of arrow C in FIG. 2), the pachinko ball can stably roll in the groove 1d.

As shown in FIG. 3, the ball pushing roller 2 is made of a cylindrical rubber inserted into a miniature bearing attached to the tip of the arm 5. Since the rotation axis of the miniature bearing is parallel to the rotation axis 4p of the motor 4, the rubber ball inserted in the miniature bearing rotates to prevent the ball from rolling along the groove 1d. I can help.

As described above, since the motor 4 only bears the weight of the arm 5, the ball pushing roller 2 attached to the tip of the arm 5 and the ball of the ball, the moment of inertia becomes small.
The change in the moment of inertia is also small. Therefore, a small motor with low power consumption can be used.
On the other hand, the automatic sphere feeder is shown in FIGS. 4 and 5. The automatic ball feeder is provided with a central axis 1 provided at one point of the panel 6.
It has a pachinko ball supply arm 11 that rotates about 1d, and this supply arm 11 has a first claw 11a and a second claw 11a.
Claw 11b is integrally formed. Supply arm 11
The tip portion 11c of the cam 1e is in contact with the cam 1e connected to the motor 4, and the cam 1e is rotated every time the motor 4 makes one rotation.
Thus, the supply arm 11 moves up and down.
As the supply arm 11 moves up and down, the pachinko ball guided by the guide portion 126 goes over the first claw 11a and enters between the first claw 11a and the second claw 11b, and the first claw is formed. 1
The pachinko ball that has entered between 1a and the second claw 11b gets over the second claw 11b and enters the communication hole 12. Then, the pachinko balls are supplied through the communication hole 12 to the inside of the container of the above-mentioned pachinko ball launching device provided on the back side of the panel 6 every one rotation of the motor 4.

Next, a rotation control device for controlling the rotation of the motor 4 will be described. This rotation control device starts from the position S (see FIG. 11) at which the roller 2 starts to push the ball to the motor 4.
The position T where the roller 2 throws out a ball
(See FIG. 11) The rotation speed of the motor 4 is set to a desired maximum speed, and the motor 4 is decelerated when the pachinko ball throwing position T is passed.

As shown in FIG. 6, the rotation control device includes a rotation control circuit 21 for controlling the number of rotations of the motor 4, a handle portion 22 for setting a pachinko ball throwing speed, and a touch portion 22c.
Touch switch circuit 23 that responds to the contact of the hand with the hand, an optical coupler 26 that connects the touch switch circuit 23 and the rotation control circuit 21, a position sensor 24 that detects the rotational position of the motor 4, a position sensor 24 and the rotation control circuit 21. A rectifier circuit 27 for supplying power to the logic circuit 25, the rotation control circuit 21, and the touch switch circuit 23, the surge absorber 28, the fuse 29, the lamp 30, the main switch 3
1 and a commercial power supply 32. The rotation control circuit 21 is provided with a power circuit for driving the motor.

The handle portion 22 is a portion touched by the player's hand, and has an adjuster 22a for manually adjusting the pachinko ball throwing speed, a switch 22b for starting a motor, and a touch portion 22c. Specifically, as shown in FIG. 7, a large-sized metallic knob is attached to a variable resistor that also serves as a switch. Alternatively, it may be independent like a microswitch.

The touch switch circuit 23 is immediately turned on when the player touches the handle, and the switch 22b is turned on after a slight delay when the handle is started to be turned a little. Start the motor. The rotation control circuit 21 sends a control signal to the motor (variable period pulse in the case of a pulse motor such as a stepping motor, variable voltage signal or variable current signal in the case of a DC motor) according to the type of the motor, and controls the rotation speed of the motor. To do.

The position sensor 24 initializes the rotation start position of the motor 4, and performs an initial position return operation when the rotation position of the motor 4 has not returned to the initial position due to a power failure or the like. .. This control content is illustrated in the graphs of FIGS. 8, 9, 10, and 13, respectively. In FIG. 8, from the position S (see FIG. 11) at which the roller 2 starts pushing the pachinko ball to the pachinko ball throwing position T.
It accelerates linearly until it reaches just before (see FIG. 11). When the ball is thrown at the ball throwing position T, the ball is decelerated linearly until it returns to the original position S. The inclination of this acceleration is determined by the angle at which the steering wheel is turned.

FIG. 9 corresponds to the case where the steering wheel is returned, as compared with the case of FIG. 8, and acceleration and deceleration are slower.
Therefore, the initial velocity of the pachinko ball (the velocity thrown out of the container 1) becomes smaller than that in the case of FIG. 8, and
The cycle of throwing the ball is also long. FIG. 10 shows that when the arm 5 reaches a predetermined position U by accelerating from the position S at which the pachinko ball starts to be pushed, the pachinko ball throwing position T (see FIG. 12).
An example in which a constant speed rotation is carried out until

The trajectory of the arm 5 when controlled according to the graphs of FIGS. 8 and 9 is shown in FIG. The arm 5 is stopped at the position S when the pachinko ball is supplied from the automatic ball supply device. Acceleration is started after a predetermined time has passed. That is, the acceleration is performed in the region (I) from the position S to the position T. As a result, the pachinko ball is pushed by the roller 2 and accelerated while drawing a circular orbit along the inner wall 1c of the container 1. As described above, the length a from the center of the arm 5 to the center of the ball pushing roller 2 is a little shorter than (radius of the inner wall 1c)-(radius of the pinball ball), and the roller 2 itself rotates. Since the ball is free, the ball is accelerated while rolling in close contact with the inner wall 1c and the roller 2. The pachinko ball reaches the maximum speed when the arm 5 reaches the position T,
At a position slightly downstream of the position T, it separates from the roller 2 and is thrown out. The arm 5 is decelerated in the area (II) until it returns to the original position S after passing the position T.

Specific numerical values in the above control will be given.
Generally, in a gaming machine, the flight distance of a pachinko ball is 0.6 to 1.2 between the position of the nail on the front and the position of the back on the gauge board.
It suffices if it can be set in the range of m. The weight of one pachinko ball having a diameter of 11 mm is 5.5 g, so that the initial velocity is 0.6 to 4.5 m / sec if the player tries to fly to the above range. The radius of the circular orbit of the side wall 1c of the container 1 is 3.6c.
m, the length a from the rotating shaft 4p to the center of the ball pushing roller 2
Is 3.0 cm, the adjustment range of the rotation speed of the motor 4 is approximately 200 rpm to 1400 rpm. If the maximum rotation speed of the motor 4 can be adjusted within this range, the pachinko ball can be moved to any position on the gauge board. The rotation speed of the motor 4 is 140
Since it will be close to 0 rpm, it will be disadvantageous if you attach a reduction gear. In this embodiment, the rotation is slowed up and down without a reduction gear.

Since the number of pachinko balls that can be fired per minute is 99.9, which is specified by national regulations, the intermittent rotation cycle of the motor 4 must be set to about 0.6 seconds or more. Therefore, the time during which the arm 5 is stopped at the position S is determined according to the intermittent rotation cycle of the motor 4. Next, FIG. 12 shows the trajectory of the arm 5 when controlled according to the graph of FIG. The arm 5 is accelerated in the area (IV) from the position S to the position U, and rotates at a constant speed in the area (V) until the position T is reached when the position U is reached. Area until returning to the original position S when reaching the position T (VI)
Then you will slow down. The pachinko ball separates from the roller 2 at a position slightly downstream of the position T.

FIG. 13 is a graph exemplifying still another control content of throwing a pachinko ball at the pachinko ball throwing position T, rapidly decelerating the ball, and then returning it to the original position S at a constant speed. The locus of the arm 5 according to the control of FIG. 13 is shown in FIG.
Shown in. The present invention is not limited to the above embodiments. For example, a rotary solenoid can be used instead of the motor. A rotary solenoid is a solenoid that rotates in one direction when energized, and returns to its original position by the force of a coil spring when deenergized (eg Shindengen Kogyo Co., Ltd.).
Rotary solenoid; model name 2E, 3E or 4E).
When this rotary solenoid is used, the control contents of the rotation control circuit 21 are as shown in the graph of FIG. That is, the ball is gradually accelerated from the initial position, the maximum speed is reached at the time of reaching the pachinko ball throwing position T, and the pachinko ball is thrown. After that, the rotor is returned to its original position by cutting the power supply to the rotary solenoid. When the rotor returns to its original position, it waits for a certain period of time before starting the next cycle. The movement of the arm 5 in this case is shown in FIG. Arm 5
When the pachinko ball is supplied from the automatic ball feeder, it stops at the position S, and acceleration starts after a lapse of a predetermined time. When the arm 5 reaches the position T, the pachinko ball reaches the maximum speed and the roller 2 And is thrown away. Arm 5
After passing the position T, the arm 5 rotates in the opposite direction by the force of the coil spring and quickly returns to the original position. Also in the embodiment using this rotary solenoid, the maximum velocity at the throwing position T can be accurately adjusted by adjusting the voltage and the current, so that the flight distance can be set accurately.

Further, the rotation control device is not limited to the circuit shown in FIG. In the circuit of FIG. 6, the power supply line is directly connected from the rectifier circuit 27 to the rotation control circuit 21, but it may be supplied through the motor start switch 22b of the handle portion 22 as shown in FIG. Other various changes can be made without changing the gist of the present invention.

[0033]

As described above, according to the first aspect of the invention, since the pachinko ball is accelerated by the revolution movement of the ball pushing portion, the centering at the time of assembly is unnecessary unlike the conventional punching structure. There is no deviation. In addition, since it is possible to suppress impact due to impact and generation of static electricity, it is possible to prevent malfunction of the electric system such as an integrated circuit, deformation of the tip of the punch, and wear, and to prolong life and improve reliability. Can be planned. Further, since it is not necessary to overcome the force of the spring as in the punching structure, the torque of the rotary driving means may be small and a small rotary driving means can be used. Further, since the rotary driving means rotates intermittently, it is advantageous in terms of heat generation as compared with the conventional case of continuous rotation. Moreover, it is not necessary to use the AC synchronous rotation driving means, and it is not necessary to separately create 50 Hz and 60 Hz.
Furthermore, no reduction gear is required. Further, the container, the rotation driving means, the ball pushing portion, and the pachinko ball supply portion can be configured with few parts, and the container, the rotation driving means, and the ball pushing portion can be integrated with a simple structure. Therefore, the entire gaming machine can be downsized. Furthermore, it is possible to accurately launch a ball of a ball, aiming at a desired position, and it is possible to manage the ball-out rate.

According to the second aspect of the present invention, since the pachinko ball can revolve around the inner wall while smoothly rolling, unnecessary friction does not occur. According to the invention described in claim 3, since the ball pushing portion can revolve the pachinko ball along the inner wall while pressing it toward the inner wall, it is possible to prevent the pachinko ball from jumping in the container. it can.

According to the invention of claim 4, the inner wall is provided with:
Since the concave groove that guides the pachinko ball along the circumferential direction is formed, it is possible to guide the pachinko ball along the concave groove even if the game machine is slightly tilted, and it is possible to maintain the orbit of the pachinko ball accurately. it can. According to the invention described in claim 5, since the pachinko ball is accelerated by the ball pushing portion in a slow-up manner, and the rotational speed of the rotation drive means at the pachinko ball throwing position can be set to a desired speed, the flight distance can be increased. It can be adjusted accurately, and the accuracy of the ball output rate can be improved.

According to the sixth aspect of the invention, the pachinko balls are fired one by one in synchronization with the rotation of the rotary drive means. Therefore, it is possible to continuously fire the ball.

As described above, according to the first aspect of the present invention, since the orbital motion of the ball guiding portion accelerates the pachinko ball, centering at the time of assembly is unnecessary unlike the conventional punching structure. There is no deviation. In addition, since it is possible to suppress impact due to impact and generation of static electricity, it is possible to prevent malfunction of the electric system such as an integrated circuit, deformation of the tip of the punch, and wear, thereby extending life and improving reliability. Can be planned. Further, since it is not necessary to overcome the force of the spring as in the punching structure, the torque of the rotary driving means may be small and a small rotary driving means can be used. Further, since the rotary driving means rotates intermittently, it is advantageous in terms of heat generation as compared with the conventional case of continuous rotation. Moreover, it is not necessary to use the AC synchronous rotation driving means, and it is not necessary to separately create 50 Hz and 60 Hz.
Furthermore, no reduction gear is required. Further, the container, the rotation driving means, the ball guiding portion, and the pachinko ball supply portion can be configured with few parts, and the container, the rotation driving means, and the ball guiding portion can be integrated with a simple structure. Therefore, the entire gaming machine can be downsized. Furthermore, it is possible to accurately launch a ball of a ball, aiming at a desired position, and it is possible to manage the ball-out rate.
