Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game ball launching device for a ball game machine using an electromagnetic actuator as a drive source.

[0002]

2. Description of the Related Art A hitting ball launching device for a conventional pachinko machine is generally a motor as a drive source. When a cam is rotated by the rotation of this motor and a spring is wound by the cam and the hoisting cam comes off. There is one that drives a firing member to fire a sphere by the restoring force of the spring.
In addition, a launching device that employs a rotary solenoid or a linear solenoid having a simple structure is known. The drive is by electromagnetic force, but the return of the launch mallet is due to the return spring and its own weight.

Further, for example, a stator of a motor in which a coil is alternately wound reversely around a plurality of stator cores arranged along a circumferential surface, and a number of permanent magnets corresponding to the stator cores N are provided along the outer peripheral surface. A rotor in which poles and S poles are alternately arranged, a means for rotatably supporting the rotor inside the stator, a firing lever for launching a pachinko ball connected to the rotor, and a rotation of the rotor. Rotation range restriction means for restricting the motion range to a rotation angle range smaller than the magnetic pole pitch of the stator,
Similarly, position regulating means for regulating the initial position of the rotor so as to impart a predetermined phase difference between the rotor and the corresponding magnetic poles of the stator, and the direction of supplying the exciting current to the coil of the stator at a predetermined timing. There is a hitting ball launching device for a pachinko machine (see Japanese Patent Laid-Open No. 5-23418) that includes a controller that outputs a drive signal that is switched alternately.

[0004]

However, the conventional firing method using a motor has a problem in that there are many parts such as a motor, a spring, and a hoisting cam, and the structure is complicated. Further, in a launching device using a solenoid, a return action of a launching member (a mallet or the like) uses a return force caused by a spring force or its own weight. However, with the method using the own weight, the return is unstable when the mallet is light. There is also a method of using a heavy mallet to ensure this unstable return, but there is a drawback that a large force is required for the firing operation and energy consumption is large.
In addition, the mallet will bounce at the start point stopper due to its free fall, and it will take a long time for the mallet to stand still. In some cases, the timing of the next launch may come before the mallet has stopped stationary, and in this case, the swing angle of the mallet at the time of launch is different, and there is a drawback in that the ball jumps unevenly. In order to solve this drawback, attaching a return device such as a spring force to the return of the mallet has a drawback that the structure is complicated and energy is lost due to a load at the time of firing.

Further, in the motor having the structure as disclosed in Japanese Patent Laid-Open No. 5-23418, a stator of a motor in which coils are reversely wound around a plurality of stator cores arranged along a circumferential surface, and the stator. The structure is complicated such that the number of permanent magnets corresponding to the iron core is composed of a rotor in which N poles and S poles are alternately arranged along the outer peripheral surface, and the structure is not easy and expensive.

In view of such circumstances, the present invention forms one coil and concentric with the coil so as to face one or a plurality of pairs of electromagnetic poles in the direction of both end faces of the coil, and to form a plurality of coils when there is no excitation. In a ball launching device of a ball game machine driven by an electromagnetic actuator having a pair of polar stable points, in an electromagnetic actuator having a plurality of pairs of polar stable points, the start point direction of the launching mallet and the ball stamping position direction Provided a game ball launching device for ball game equipment, which is arranged so as to have a stable pole and drives the launch mallet by switching the electric pallet signal between the ball stamping firing direction and the return direction to the start position. The purpose is to do.

[0007]

The present invention is intended to solve the above-mentioned problems, and employs the following technical means. In the invention according to claim 1, one coil and a pair or a plurality of pairs of electromagnetic poles are formed concentrically with the coil so as to face each other in the direction of both end faces of the coil, and a plurality of pairs of polar stable poles are formed in the absence of excitation. In a ball launching device of a ball game machine driven by an electromagnetic actuator having points, an electromagnetic actuator having a plurality of pairs of polar stable points, and a polar stable point in the starting point direction of the launching mallet and the ball stamping position direction. The technical means of driving the launching mallet by switching the electric pulse signal between the ball stamping firing direction and the return direction to the start position is adopted.

According to the invention of claim 2, claim 1
In addition to the described invention, the launch mallet normally waits at the ball stamping launch position, the launch mallet returns to the start position by the pulse signal in response to the launch command, and after the set time, launches in the ball stamping direction from the start position. The technical means of stamping and firing a ball with a ball stamping pulse signal for driving a mallet was adopted.

According to a third aspect of the present invention, in addition to the first or second aspect of the present invention, the flight force adjusting member capable of adjusting the flight force by the player operating the firing handle member. Adopted the technical means of having.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment will be described in detail below with reference to FIGS. According to the present invention, as a rotary solenoid used for driving a launching mallet, a turning point for switching a pole stable point is provided between a starting point and a launching point of the launching mallet to stabilize ball flight.

[0012] Then, the ball jump is caused by the swing of the launch mallet.
Because it depends on the energy given to the sphere, it was done by changing the energy given to the sphere by changing the swing angle of the launch mallet.

In addition, since the mass of the launching mallet is constant, the energy given to the ball for flying the ball is constant when the swing angle of the launching mallet is constant. It depends on the speed. To change the ball jump, a detection member that detects the amount of rotation angle of the firing handle, such as an encoder or volume, is installed in the handle to detect the rotation angle, and the electrical energy of the firing pulse is varied according to the rotation angle to vary the launch mallet speed. It was done by doing.

The electric energy can be varied by controlling the rising curve of the current, varying the applied voltage, PWM (variable pulse width) of the applied pulse, or a combination thereof.

As a first embodiment, as shown in FIGS. 1 and 2, a first rotary solenoid is attached to a rotary solenoid mounting plate 11 provided on the main body of a ball game machine, and a shaft 1 of the first rotary solenoid is attached. A launching mallet 12 is attached to one end and is fixed by a fixing member 13.

Next, the first rotary solenoid, which is the drive source, will be described. Regarding the two poles, a disk is formed so as to cover the magnet rotor 2 fitted to the shaft 1 supported by the bearing 3. A front-side electromagnetic pole 4 having a substantially semi-circular shape, and a back-side electromagnetic pole 5 having a substantially semi-circular disk shape that is combined and covered so as to face the front-side electromagnetic pole 4, A coil 6 wound around a cylindrical bobbin is provided so as to surround the electromagnetic pole 4 and the back electromagnetic pole 5, and is assembled by being covered with a cylindrical yoke 7 so as to surround it from the outside.

Further, by magnetizing the electromagnetic pole by the magnetic flux generated by the energization of the coil 6, the magnetic pole and the magnetic pole of the permanent magnet rotor rotate due to the attractive repulsive force, and when not energized. In the above, the binding force is provided by the attractive force between the permanent magnet rotor and the electromagnetic pole.

As shown in FIG. 2, the cylindrical bobbin for the coil is provided with a protrusion 8 for aligning the front side electromagnetic pole 4 and the back side electromagnetic pole 5 to stabilize the alignment and the gap. It can be maintained in a state. The projection 8 may have various shapes, and various designs may be used as long as they serve as a guide for positioning and assembling. In addition, this is also a guide when assembling, so that the assembly is easy.

Further, in the structure shown in FIG. 1, the yoke 7 is not integrated with the front side electromagnetic pole 4 or the back side electromagnetic pole 5, but is integrated with either the front side or the back side electromagnetic pole. It is also possible. It is also possible to divide the yoke 7 in the middle of the front side and the back side, and integrate the front side electromagnetic pole 4 and the front side yoke 7, and the back side electromagnetic pole 5 and the back side yoke 7 into one electromagnetic pole yoke. Although the embodiment describes a two-pole rotary solenoid, the same applies to a rotary solenoid having a plurality of (even) poles such as four poles and six poles.

The relationship between the rotary solenoid mounting plate 11 and the launch mall 12 as shown in FIG. 3 will be described. The rotary solenoid mounting plate 1 provided on the main body of the ball game machine.
The first rotary solenoid is attached to the first
A launching mallet 12 is attached to one end of a shaft 1 of the rotary solenoid, and is fixed by a fixing member 13. Further, a start position stopper 15 and a ball stamping position stopper 16 are appropriately positioned on the rotary solenoid mounting plate 11. It is provided in.

Next, as a second embodiment, as shown in FIGS. 4 and 5, a second rotary solenoid is attached to a second rotary solenoid attachment plate 11 provided in the main body of the ball game machine, and the second rotary solenoid is attached. A launching mallet 12 is attached to one end of the shaft 1 and is fixed by a fixing member 13.

Next, the second rotary solenoid, which is the drive source, will be explained.
Since it is formed on the outer periphery through the bracket 9, and the other structure and concept are the same as those of the first embodiment, a detailed description will be omitted and a brief description will be given. A bracket 9 is provided so that a magnet rotor 2 is provided on an outer periphery of an end portion 10 of a shaft 1 that is supported by a bearing 3 attached to a front side electromagnetic pole 4 and a back side electromagnetic pole 5, and a magnet rotor is provided at the other end of the bracket 9. 2 is provided so as to cover the front side electromagnetic pole 4 and the back side electromagnetic pole 5, and is provided so as to cover the whole with the case 14. The number of poles is 2
Although the poles have been described, it is needless to say that the number of rotary solenoids having an even number of poles such as 4 poles and 6 poles can be similarly increased.

Next, a third embodiment will be described with reference to FIG. The third embodiment is substantially the same as the first embodiment shown in FIGS. 1 to 3 except that the launching mallet 12 is attached to the rotary solenoid body and the shaft 1 is attached to the mounting plate 11. Since the configuration is the same as that shown in the first embodiment, the description will be omitted because it will be repeated. Needless to say, the second rotary solenoid can be attached.

An example of drive pulse timing according to the present invention will be described with reference to FIG. In the example of firing operation by handle switch signal and touch switch signal, when both are turned on, the operation is performed, but even if the signal is interrupted on the way, sequence operation until the end of the firing pulse is performed. Return of the firing mallet added to the rotary solenoid The pulse width of both the pulse and the firing pulse need only be the width of the operating time of the firing mallet 12.

[0025]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) Since there are stable points both at the start point and the launch point, the launch mallet can be quickly stabilized at both points, and the launch mallet can always move from the stationary state to the next operation, thus stabilizing the ball flight. (2) Since the repulsive force and the attractive force work synergistically depending on the direction of energization, energization energy can be small. (3) In the solenoid type, the return force of the launching mallet is unstable, so the energy of the launching mallet was used for the replenishing device that sends the next launch ball one by one to the launching position. With the replenishing device, the extra electromagnet is no longer needed. (4) Since the replenishing device used in the motor system can also be used, the rotary solenoid system having a simple structure can be directly replaced. (5) Adjust the mallet tip so that the launch mallet hits the center of the ball correctly, but the adjustment work has become easier because the launch mall has a stop point. (6) Since the structure of the actuator can be disassembled into individual parts such as a single coil, an electromagnetic pole, a rotor, and a bearing, it is easy to recycle each part. Also, since it is easy to separate from iron and copper, it is suitable for recycling in material units. (7) Since the shape of one coil is cylindrical, it is possible to create the coil independently, which is extremely simple and inexpensive compared to the conventional coil wound around a special shape. .
