Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention launches a pachinko ball by rotating a launch arm by a motor and hitting a pachinko ball supplied from a pachinko ball supply container with a ball striking piece at the tip of the launch arm. The present invention relates to a pachinko ball supplying / launching device.

[0002]

2. Description of the Related Art As a structure for firing a pachinko ball, there is known a structure in which a hitting mallet is attached to an output shaft of a motor, and a ball hitting portion at the tip of the hitting mallet continuously hits balls supplied to a launch rail. (Japanese Patent Laid-Open No. 63-305893).
In the above-mentioned prior art, it is necessary to install a ball supply device for continuously supplying the balls to the launch rail.

[0003]

The structure of this sphere supply device is, for example, [0005] in Japanese Patent Laid-Open No. 5-285253.
As described in the paragraph, it requires a rocking arm for delivering each pachinko ball one ball at a time. Therefore, the speed at which the balls are supplied from the ball supply device is slowed down, and if an attempt is made to increase the speed, the ball supply device is forced to perform an unreasonable operation, and the frequency of failure increases.

Therefore, the present invention is for supplying a sphere,
It is an object of the present invention to realize a pachinko ball supply / launching device that does not require a particularly complicated structure, is compact, and has few failures.

[0006]

[0007]

A pachinko ball supply / launch apparatus of the present invention controls a launch arm for striking a pachinko ball supplied from a pachinko ball supply container, a motor for rotating the launch arm, and rotation of the motor. Rotation control means, the pachinko ball supply container is in the shape of a slanted long groove, a hole through which a ball striking piece of the firing arm is inserted is formed at a position on which the firing ball is placed, and the rotation control means starts. Rotate the firing arm from position S to ball firing position F,
After the ball is launched, it starts to rotate in the opposite direction and returns to the start position S (claim 1 ).

According to this structure, when the balls are guided one by one by the slanted slot-shaped pachinko ball supply container to the position where the ball is placed, the ball striking piece of the shooting arm hits the shooting ball through the hole. After firing the ball, the firing arm starts rotating in the opposite direction and returns to the start position S. Therefore, if a plurality of balls are placed on the slanted long groove portions of the pachinko ball supply container, the balls can be sent by gravity and can be fired one by one. As a pachinko ball supply container, no special mechanism for sending balls is required.

[0009] The rotation control means may be a control for rotational acceleration from the start position S to the firing position F of the sphere, rapid
After acceleration, control may be performed to maintain a constant rotation speed (claims 2 and 3 ). The rotation control means preferably rotates the firing arm from the start position S to the firing position F of the sphere and then temporarily stops it (claim 4 ). This is to prevent the ball hitting piece from hitting the pachinko ball supply container. Also, even if the ball striking piece hits the pachinko ball supply container,
This is to reduce the impact.

When the ball striking piece of the launch arm reaches the hole of the pachinko ball supply container and hits the ball, a shock absorbing material may be installed on the motor mounting plate (claim).
5 ). This is to reduce the impact when the ball striking piece hits the pachinko ball supply container. Examples of the cushioning material include springs and elastic rubber. It is preferable that the motor is a stepping motor or a DC motor (claim 6 ).
This is because the rotation angle can be controlled freely.

The pachinko ball launching device can be installed at any position on the pachinko machine (claim 7 ). This is because by setting the firing position F of the sphere at an arbitrary angle, the sphere can be fired in any direction such as vertically upward or diagonally upward.

In this state, the firing arm 3 is temporarily stopped at the firing position F after hitting the ball. The ball is about to jump out of the pachinko ball supply container 2 in the direction of the arrow. The position where the firing arm 3 stops once is a position where the ball striking surface of the ball striking piece 4 is horizontal in order to fire the pachinko ball vertically upward. FIG. 12 is a front view showing a state after the launch ball has been launched. Once stopped, the launch arm 3 is further rotated, the launch ball in the pachinko ball supply container 2 is already fired, and the pachinko ball supply container 2 is empty.

FIG. 3 is a block diagram showing a motor control circuit of the pachinko ball launching device 1. In this figure, the illustration of the power supply portion is omitted.

The motor control circuit includes a firing number control circuit 41,
The rotation control circuit 42, the touch switch circuit 43, the initialization circuit 44, the driver circuit 46, and the position sensor S,
Have F. The firing rate control circuit 41 is composed of an astable multivibrator that outputs a firing rate pulse. The number of shots is set to be 99.9 times / minute or less according to domestic regulations. This pulse is supplied to the counter that controls the number of shots and also to the rotation control circuit 42.

The rotation control circuit 42 is an astable multivibrator which supplies a rotation speed control signal to a driver for driving the motor 9. The initialization circuit 44 is a circuit that sets the rotational position of the motor 9 to the start position S by driving the rotation control circuit 42 regardless of whether the touch switch circuit 43 is on or off when the motor control circuit is started up. When the player touches the metal part of the handle H,
The touch switch circuit 43 operates to turn on the firing number control circuit 41 and the rotation control circuit 42.

The rotation control circuit 42 adjusts the acceleration force (angular velocity) of the motor 9 and the strength of sudden start (high speed, low speed). The resistance value of the variable resistor (potentiometer) in the handle H changes in response to the player moving the handle H by hand to adjust the rotation. The periodic pulse of the rotation control circuit 42 changes according to this resistance value. That is, as the handle H is turned to the right, the pulse cycle of the rotation control circuit 42 is shortened and the rotation speed of the motor 9 is increased. On the contrary, if the handle H is returned, the pulse period becomes longer and the rotation speed of the motor 9 is lowered. Therefore, the rotation speed of the motor is determined by the angle at which the handle H is turned.

This periodic pulse signal is supplied to the driver circuit 46.
Is input to the motor 9 and the rotation speed of the motor 9 changes according to the output of the driver. In this embodiment, since the stepping motor 9 is used, it is possible to finely adjust the firing force.
FIG. 15 is a graph showing the change over time in the rotation speed of the motor 9. The vertical axis shows the rotation speed and the horizontal axis shows the time. In the region I, the firing arm 3 is accelerated from the start position S to the firing position F. The solid line shows the case of firing at high speed, and the broken line shows the case of firing at low speed. This high speed control and low speed control are determined by the turning angle of the handle H, as described above.

When the motor 9 finishes the acceleration in the region I,
The rotation is stopped at the firing position F. The motor 9 is stopped by energizing the motor 9 with a current I larger than that for acceleration and magnetically holding the current. Then, in region II again, low speed rotation is performed at a constant speed. Because it is slow, it does not consume as much current as when accelerating or stopping. When the start position S is reached, one cycle is completed. The rotation speed control of the motor 9 is not limited to the form shown in FIG.

FIG. 16 is a graph in the case of rapid firing at a constant speed. The solid line shows the case where the handle H is turned to the maximum and fires at high speed, and the broken line shows the case where the handle H is minimized and fired at low speed. -Second Embodiment- Fig. 17 is a front sectional view of a pachinko ball launching device 1 and a pachinko ball supply container 2 according to a second embodiment of the present invention.

The difference from the firing arm 3 of FIG. 2 is that there is no kerf 21 in the ball transfer portion of the pachinko ball supply container 2,
The ball striking piece 4 of the firing arm 3 is provided with a kerf 21 after hitting the ball.
Can't pass through. Instead, a hole 22 is formed in the bottom of the ball transfer portion of the pachinko ball supply container 2, and the ball striking piece 4 of the launch arm 3 that has rotated at high speed from the start position S shoots the launch ball through this hole 22. It hits the ball, stops, and then rotates back to the start position S again. That is, the motor 9 and the firing arm 3 reciprocally rotate. The other structure is the same as that of FIG.

FIG. 18 is a plan view showing the positional relationship between the firing arm 3 and the pachinko ball supply container 2. The pachinko ball supply container 2 is shown in a sectional view. Pachinko ball supply container 2
Unlike the shape of FIG. 8, there is no kerf 21 and the firing arm 3 cannot pass through. A round hole 22 having a gap is formed at the bottom of the ball transfer portion so that the ball striking piece 4 does not come into contact with the pachinko ball supply container 2.

19 to 21 show a series of operations accompanying the rotation of the firing arm 3. FIG. 19 shows the firing arm 3
Is rotated from the start position S and the ball striking piece 4 is in the hole 2
It is sectional drawing which shows the moment which contacts a sphere through 2. Figure 2
0 is a sectional view showing the moment when the ball striking piece 4 of the firing arm 3 hits the ball. In this state, the firing arm 3 is temporarily stopped at the firing position F after hitting the ball. The ball is about to jump out of the pachinko ball supply container 2 in the direction of the arrow.

FIG. 21 is a front view showing a state after the launch ball has been launched. The firing arm 3 once stopped is starting to rotate in the reverse direction. The launch ball in the pachinko ball supply container 2 has already been fired, and the pachinko ball supply container 2 is empty. FIG. 22 shows a state in which the launch ball is launched vertically from the pachinko ball launching device 1 toward the guide rail GR at a high speed. In FIG. 22, a state in which the firing arm 3 reciprocates between the firing position F and the start position S is shown by a chain line and a circle.

The region from the start position S to the firing position F is denoted by I, and the region from the firing position F to the start position S is denoted by II. In this figure, the angles of the regions I and II are 90 °, but the angle is not limited to this. When accelerating and firing as shown in FIG. 23 described later, 1
It is preferable to set the angle to 5 ° to 180 °, and it is preferable to set to 7.5 ° to 90 ° in the case of rapid firing as shown in FIG.

The firing arm 3 is accelerated and rotated from the start position S toward the firing position F, hits a ball when reaching the firing position F, and the ball is fired in the direction indicated by the arrow T. Firing arm 3
Stops once, starts moving again, and rotates the region II at a constant speed at a low speed to return to the start position S. In the meantime, the next ball rolls on the pachinko ball supply container 2 and is supplied to the ball transfer part. This operation is repeated while the player continues to play the game. FIG. 23 is a graph showing the change over time in the rotation speed of the motor 9. The vertical axis shows the rotation speed and the horizontal axis shows the time. In the region I, the firing arm 3 is accelerated from the start position S to the firing position F. The solid line shows the case of firing at high speed, and the broken line shows the case of firing at low speed. The control of high speed and low speed is determined by the turning angle of the handle H.

When the motor 9 finishes the acceleration in the region I,
The rotation is stopped at the firing position F. The motor 9 is stopped by energizing the motor 9 with a current I larger than that for acceleration and magnetically holding the current. Then, in region II again, low speed rotation is performed at a constant speed in the opposite direction. Because it is slow, it does not consume as much current as when accelerating or stopping. When the start position S is reached, one cycle is completed. The rotation speed control of the motor 9 is not limited to the form shown in FIG.

FIG. 24 is a graph in the case of rapid firing at a constant speed. The solid line shows the case where the handle H is turned to the maximum and fires at high speed, and the broken line shows the case where the handle H is minimized and fired at low speed. FIG. 25 is a front view showing a modified example of the pachinko ball launching apparatus 1 using a cushioning material. 26 is a side view and FIG. 27 is a plan view. Attach the annular fixture 51 to the mounting plate 8 of the pachinko ball launching device 1,

On the other hand, an impact receiving surface 31 that comes into contact with the coil spring 52 is provided around the position where the ball striking piece 4 is attached to the firing arm 3. The inner diameter of the annular fixing tool 51 and the inner diameter of the coil spring 52 are larger than the outer diameter of the ball striking piece 4, and the ball striking piece 4 passes without colliding with the coil spring 52 and the annular fixing tool 51, and from below. You can hit the ball.

According to this structure, after hitting the ball, the rotational force of the firing arm 3 is absorbed by the coil spring 52, and the rotation speed of the firing arm 3 naturally decreases to zero. Therefore, the motor 9 as described with reference to FIG.
There is no need to force stop. Since this large current is not required, power can be saved. In addition, a cushioning material,
The firing arm 3 may be stopped in combination with the forced stop of the motor 9. In this case, the current for forcibly stopping the motor 9 may be smaller than that described with reference to FIG. Further, as the motor 9, as shown in FIG.
Although the stepping motor is used in FIG. 3, it may be a DC motor because it is forcibly stopped by using a cushioning material. In this case, the rotation speed of the DC motor is controlled by the voltage value or the current value, and the forward / reverse rotation is performed by switching the positive / negative polarity.
At the time of forced stop, the voltage or current is cut off to 0, so that power can be saved.

28 and 29 are front views of the pachinko ball launching device 1 in which the contact position of the coil spring 52 of the launch arm 3 and the mounting position of the ball striking piece 4 are different. 28 shows an example in which the impact receiving surface 31 that comes into contact with the coil spring 52 is provided at a position close to the rotation center of the firing arm 3, and FIG. 29 shows an example in which the impact receiving surface 31 is provided at a position far from the rotation center of the firing arm 3. Indicates. In any case, FIGS.

Since the impact receiving surface 31 of the firing arm 3 needs to receive the coil spring 52 having a circular cross section, it has a circular shape as viewed from above. In this embodiment, since it is not necessary to pass the ball striking piece 4 through the circular fixing tool 53 and the coil spring 52, the circular fixing tool 53 and the coil spring 52 can be downsized. FIG. 32 is a cross-sectional view when a cylindrical member 54 made of hard elastic rubber is used as the cushioning material.

The cylindrical member 54 is fitted and fixed to an annular fixing member 55 fixed to the mounting plate 8. The inner diameter of the annular fixture 55 and the inner diameter of the cylindrical member 54 are larger than the outer diameter of the ball striking piece 4.
The ball can be hit and passed without colliding with the ring fixing tool 55 or the ring fixing tool 55. As a material of the cylindrical member 54, in addition to elastic rubber, a plastic material having elasticity such as hard polyethylene or polyimide (nylon) may be used. If the firing arm 3 is a plastic material, a ceramic material or a metal material may be used.
