Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hitting ball launching device mainly used in a game board (so-called pachinko machine).

[0002]

2. Description of the Related Art Conventionally, it has been known, for example, in Japanese Patent Publication No. 57-15917 that a rotary solenoid is used as a drive actuator of a ball striking device for a pachinko machine, and the rotary solenoid is excited to urge the ball. is there.

[0003]

However, since the conventional rotary solenoid does not use a magnet when it is unexcited, no attraction force or the like is generated, and the ball hitting rod returns after hitting. It depends on the rod returning to its own weight. As a method of increasing the returning force of the hitting rod, there is a method of using a return spring inside or a method of making the weight of the hitting rod heavy, but in both cases, the force at the time of hitting the ball is the restoring force of the hitting rod. However, there is a disadvantage in that a larger driving force is required, which results in poor operating efficiency. In particular, when the ball hitting rod is returned by its own weight, other work such as ball throwing cannot be performed, and another actuator (solenoid etc.) dedicated to ball throwing is separately required, and in this case, accessory parts increase. In addition, it is necessary to separately generate a signal for launching a ball and for launching a ball, resulting in a significant increase in cost.

Further, in the conventional rotary solenoid, since the inner rotor is an exciting iron core, in order to increase the hitting force, an air gap between the exciting iron core and a magnetic pole iron core arranged opposite to the outer circumference of the exciting iron core. Needs to be as small as possible,
Therefore, both iron cores require ultra-precision processing such as polishing and finishing, which requires a large amount of cost, and is difficult to assemble, and in addition, the air gap is 0.
Since it is as small as 1 mm, defects such as scratches between the iron cores during assembly frequently occur. In addition, there is a drawback that troubles during use easily occur, such as scratches, if there is a slight change in the positional relationship of internal parts during use.

The present invention has been made in view of the above points, and it is an object of the present invention to make it possible to reliably perform a ball hitting ball launching operation and a ball hitting ball supplying operation, and to hit a ball hitting rod. The problem is to alleviate the impact at the time, the problem is to prevent the drive unit from moving out of the operating range, and the operation of supplying and stopping the ball by the ball supplying device can be performed with a simple structure. In addition, it is an object to obtain a step motor that is small in size, power saving, and can be powered up and has a strong hitting force. Furthermore, even if the air gap between the rotor and the magnetic pole iron core is large, the hitting force is strong. It does not require ultra-precision processing such as polishing finish,
It is an object to obtain a step motor which has few troubles during use, has a simple structure, is inexpensive, and is highly reliable.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described.

FIG. 1 is a schematic view of a hitting ball launching device used in a so-called pachinko machine. This hitting ball launching device includes one step motor 1 and a rotary shaft 5 of the step motor 1.
The hitting rod 2 and the driving unit 4 connected to the driving unit 4 and the hitting ball supply device 12 driven by the driving unit 4.

The rotating shaft 5 of the step motor 1 is rotatably held by a bearing or the like, and the hitting rod 2 is integrally fixed to the rotating shaft 5 by a nut 21. At one end of the ball striking rod 2, a ball striking portion 3 having a coil spring 3a for driving and firing a ball 8 (a so-called pachinko ball) supplied to a projecting portion P is integrally provided, and the ball striking rod 2 is also provided. At the other end, a driving unit 4 for driving a hitting ball supply device 12 for supplying the hitting ball 8 to the launching section P is integrally provided. The drive unit 4 converts the rotational movement of the hitting rod 2 into a vertical linear movement of an opening / closing lever 9 which will be described later, and has a rounded tip.

FIG. 2 shows the internal structure of the step motor 1. The step motor 1 includes, for example, a 4-pole stator 17
And the coils 16 wound around these stators 17, respectively.
And a rotor 14 and the like that are integrally fixed to the rotary shaft 5 of the step motor 1. The coil 16 is wound around each stator 17 so that the polarity of the stator 17 is alternately magnetized into N pole and S pole when energized. Further, the rotor 14 has N poles and S poles alternately magnetized radially around the rotating shaft 5, and in the present embodiment, the number of poles of the rotor 14 is four poles, which is the same as the number of poles of the stator 17. It is magnetized. Here, when the ball is not hit and the hitting rod 2 and the hitting portion 3 are in the positions shown by the solid lines in FIG. 1, the coil 16 is energized in the direction in which the polarity of the stator 17 is magnetized as shown in FIG. Then, the rotor 14 is attracted in the direction C of the arrow in the figure, and the striking rod 2 and the striking portion 3 rotate to the positions indicated by imaginary lines 2'and 3'in FIG. It is done. In the magnetic pole arrangement as shown in FIG. 2, the operating angle of the batting rod 2 is within 45 °. Therefore, the operating angles of the batting rod 2 and the drive unit 4 are within 45 °. The operating angle of the rod 2 can be changed by the number of poles of the stator 17 and the rotor 14. For example, when the stator 17 has two poles, the operating angle of the ball striking rod 2 is 90 °.
Within 6 °, within 30 ° for 6 poles, within 8 °
Although it is within 22.5 °, it is desirable that the number of poles of the stator 17 and the rotor 14 is 4 or less for safe operation. Further, in the case of two poles, the generation of the suction force is restricted, so it is desirable to set the number of poles to four as shown in FIG.

At the upper limit position of the range of rotation of the hitting rod 2, there is provided a rotation restricting stopper 6 for restricting excessive rotation of the hitting rod 2 when hitting by the hitting portion 3. The rotation restricting stopper 6 is made of an elastic material such as rubber, prevents overrun of the hitting portion 3 at the time of hitting, makes the strength of the hitting ball 8 constant, and reduces impact at hitting. It is for doing. On the other hand, a positioning stopper 7 for positioning the drive unit 4 at a predetermined position corresponding to the hitting ball supply device 12 is provided at the lowermost position of the rotation range of the hitting rod 2. The positioning stopper 7 is made of, for example, an elastic material such as rubber, and after the ball striking device is assembled, the ball striking rod 2, that is, the driving portion 4 integrated with the ball striking rod 2 is moved out of a predetermined operating range by some impact. This is for preventing the hitting and supplying the hitting ball 8 from the hitting ball feeding device 12 more reliably.

A hit ball supply device 1 located above the drive unit 4.
Reference numeral 2 is composed of an inclined standby rail 20 for successively arranging a plurality of hit balls 8 in a standby state, and an opening / closing lever 9 for opening / closing an exit 20a of the standby rail 20 which is movable in the vertical direction. The opening / closing lever 9 is formed with an elongated hole 30 elongated in the vertical direction B, and the opening / closing lever 9 is supported by the guide 31 inserted into the elongated hole 30 so as to be movable in the vertical direction B. The lower end of the opening / closing lever 9 is placed on the upper surface of the drive unit 4, and a lever stopper 11 is formed at the upper end of the opening / closing lever 9 so as to project forward and backward to the exit 20a of the standby rail 20. When the lever 9 is moved up and down, the lever stopper 11 moves the exit 2 of the standby rail 20.
It has a structure for opening and closing 0a. Reference numeral 10 in the figure is an inclined rail that guides the hit ball 8 supplied from the standby rail 20 to the launching portion P.

Next, the operation will be described. First, when a direct current is applied to the coil 16 of the step motor 1, the stator 17 is excited, the rotor 14 rotates forward, and the striking rod 2 is attached to the positions indicated by phantom lines 2'and 3'in FIG. The coil spring 3a mounted on the hitting portion 3 drives the hitting ball 8 supplied to the launching portion P in the direction indicated by the arrow A. At this time,
The striking rod 2 hits the rubber rotation restriction stopper 6 to prevent overrun of the striking rod 2, so that the strength of the striking ball 8 can be made constant, and at the same time, the striking portion 3 and other portions (the firing portion P).
It is possible to avoid unnecessary collisions with other objects, and to reduce the impact when hitting a ball. Further, at this time, the drive unit 4 projecting from the other end of the ball striking rod 2 is rotated in the direction of lowering the opening / closing lever 9 in association with the rotation of the ball striking rod 2, and the lever stopper 11 is moved to the exit of the standby rail 20. 20a is opened for a moment, and one hitting ball 8 is pushed out by the guide rail 10 leading to the launching part P. Further, after the hitting ball 8 is fired, the rotor 14 is rotated in the reverse direction by the attraction force between the stator 17 and the rotor 14, so that the hitting rod 2 and the hitting portion 3 can be returned to the positions indicated by the solid lines in FIG. By rotating the opening / closing lever 9 in the direction of raising it, the lever stopper 11 blocks the outlet 20a of the standby rail 20 and stops the supply of the hit ball 8 to the launching portion P. At this time, since the returned ball striking rod 2 hits the positioning stopper 7 made of rubber, it is possible to prevent the ball striking rod 2 and the drive unit 4 integrated with the ball striking rod 2 from coming out of the predetermined operating range. The drive unit 4 does not hinder the operation of supplying the hit ball 8.

As described above, one step motor 1 can be used as an actuator for operation to perform the firing operation of the hit ball 8 and the supply operation of the hit ball 8, and moreover, the hit ball is generated by the attraction force between the stator 17 and the rotor 14. Since the returning operation of the rod 2 can be performed, it is not necessary to rely on the returning of the hitting rod 2 after the hitting ball to the self-weight return of the hitting rod 2 or to separately provide a return spring as in the conventional case. There is no problem that the force of the ball striking rod 2 at the time of hitting is canceled by the self-weight of 2, the return spring, etc., so that a larger driving force is obtained and the operating efficiency is improved. Further, since the stepping motor 1 for driving the hitting rod 2 can be used to drive the hitting ball supply device 12 by urging the driving unit 4, a conventional actuator (solenoid) dedicated to hitting a ball is separately provided. No need. In addition, the drive unit 4 that is urged to rotate by the rotating shaft 5 of the step motor 1 is arranged in correspondence with the opening / closing lever 9 that opens and closes the exit 20a of the standby rail 20 of the hitting ball supply device 12, and is inexpensive. And hit ball 8
There is an advantage that the supply operation and the supply stop operation can be surely performed.

Another embodiment of the present invention is shown in FIGS. In this embodiment, the rotor 14 of the step motor 1
However, as shown in FIG. 5 (a), it is composed of a permanent magnet 14a in which N poles and S poles are alternately magnetized in four poles on the outer periphery, and a rotor bush 41 is arranged at the center of this permanent magnet 14a. . The rotor bush 41 holds the permanent magnet 14a (holds it by adhesion or caulking), and
It is used for transmitting a force to the ball striking rod 2. Both ends of the rotor bush 41 are rotatably held by bearings 42 shown in FIG. The bearing 42 is fixed and held by a bearing holder 43. Further, four magnetic pole iron cores 40 are arranged facing each other at equal intervals at four locations on the outer peripheral side of the permanent magnet 14a. Of the four magnetic pole iron cores 40, the magnetic pole iron cores 40 facing each other are shown in FIG. The two magnetic pole cores 40 are connected to the upper stator 45 by means such as caulking or welding, and the other two magnetic pole cores 40 facing each other shown in FIG. 5C are four columns. Together with 44, they are connected to the lower stator 46 by means such as caulking or welding. That is, as shown in FIGS. 4 and 5A to 5C, there are the same number of magnetic pole iron cores 40 as the number of the magnetic poles of the rotor 14, and each magnetic pole iron core 40 is located on the upper stator 45 side and the lower stator 45 side. Side stator 4
Half of them are alternately arranged on the 6 side at equal angles. In this embodiment, half (2 poles) of the total number of poles of the magnetic pole iron core 40 is arranged on the upper stator 45 side, and the remaining half (2 poles) is arranged on the lower stator 46 side. That is, half each
A state in which half of the total number of poles of the magnetic pole iron core 40 is arranged on the upper stator 45 side and the remaining half is arranged on the lower stator 46 side. Here, the upper stator 45 and the lower stator 4
6, the magnetic pole iron core 40 and the support column 44 are each made of an iron-based material, and form a magnetic pole circuit together with the permanent magnet 14a. Reference numeral 47 in FIG. 4 is a connecting shaft between the rotor bush 41 and the ball striking rod 2, 48 is a nut, 49 is a coil frame, and 50 is a coil. In this embodiment, the permanent magnet 1
Although the number of magnetic poles of 4a is 4 poles, it may be 4 poles or more or 4 poles or less.

When no current is flowing through the coil 50, the ball striking rod 2 is stopped by being supported by the positioning stopper 7 at the position shown by the solid line in FIG. Now coil 50
When a current flows through the ball and the striking rod 2 moves to the position shown by the phantom line 2'in FIG. 3, the position of the permanent magnet 14a is changed to that in FIG.
Assuming the state of (a), the polarities of the magnetic pole iron cores 40 at that time are such that the two magnetic pole iron cores 40 shown in FIG.
A current may be applied to the coil 50 so that the remaining two magnetic pole iron cores 40 shown in FIG. Since the rotor 14 is composed of permanent magnets 14a in which N poles and S poles are alternately magnetized in a plurality of poles, a comparison is made with a conventional case where the inner rotor of the rotary solenoid is an exciting iron core. In addition to powering up, the coil spring 3a is attached to the ball striking portion 3, and the ball striking ball 8 is launched by the spring force of the coil spring 3a. The step motor 1 can be further strengthened, and as a result, it is possible to obtain the step motor 1 that is small in size, power saving, and has a strong hitting force. Also, an air gap G between the permanent magnet 14a and the magnetic pole iron core 40
Since the hitting force can be increased even if the value is large, the air gap G is changed from the conventional 0.1 mm to, for example, 0.2 mm to 0.4
m may be increased, and even if compared with rotary solenoids of the same size, sufficient flight force can be generated with the same current value. Further, since the large air gap G can be secured as described above, there is no concern that defects such as scratches between the assembled components will occur, and along with this, there will be no need for ultra-precision machining such as polishing finish, and the cost will be reduced. The structure is simple, and the structure is simple, and there is no fear of scratches due to changes in the positional relationship of parts during use, and troubles during use can be reduced. There is an advantage that it is possible to obtain the step motor 1 that is inexpensive and highly reliable.
