[Industrial applications]

 The present invention relates to a pachinko launcher structure, and more particularly, to a new improvement for obtaining a small and simple structure for driving a hammer using an electromagnetic outer rotor type finite angle torquer.

[0002]

[Prior art]

 As a pachinko launcher structure of this type that has been conventionally used, for example, the structure shown in FIG. 4 is used. That is, the reference numeral 20 in FIG. 4 is a synchronous motor having a cam 21, and a hammer 8 corresponding to the cam 21 is rotatably provided in the direction of arrow A via a shaft support 22. . The return spring 23 connected to the hammer 8 is connected to the operation handle 25 via a pulley 24, and the pulley 24 is biased by a biasing spring 26. Therefore, in the above-described configuration, the hammer 8 is reciprocally rotated in the direction of arrow A by the rotating cam 21, and the hammering strength of the hammer 8 is adjusted by operating the operation handle 25.

[0003]

[Problems to be solved by the device]

 Since the conventional pachinko launcher structure is configured as described above, the following problems exist. In other words, since the hammer was hit by the cam, a synchronous motor and a cam were required, the structure was complicated, and it was extremely difficult to reduce the size and cost.

The present invention has been made to solve the above problems, and in particular, is a pachinko launcher structure of a small and simple structure for driving a hammer using an electromagnetic outer rotor finite angle torquer. The purpose is to provide.

[0005]

[Means for Solving the Problems]

 The pachinko launcher structure according to the present invention is a pachinko launcher structure in which a hammer that is rotatably provided is used to shoot a ball, and a ring-shaped rotor having the hammer mounted on its outer periphery and the ring-shaped rotor are A fixed shaft member that is rotatably held via a bearing and is located inside the ring-shaped rotor, a ring-shaped stator that is provided on the fixed shaft member and is located inside the ring-shaped rotor, and a ring-shaped rotor that covers the ring-shaped rotor. A fixed cover body provided on the fixed shaft body, a stator coil provided on the outer periphery of the annular stator and corresponding to the annular rotor, and a spring member wound around the outer periphery of the annular rotor. It is a configuration provided with.

More specifically, the fixed cover body is fixed to a mounting plate.

[0007] More specifically, the configuration is made up of one or a plurality of rotor teeth formed on the ring-shaped rotor and one or a plurality of stator teeth formed on the ring-shaped stator and corresponding to the rotor teeth. is there.

[0008]

[Action]

 In the pachinko launcher structure according to the present invention, when the stator coil is excited, the ring-shaped rotor rotates (about 60 degrees) against the spring force of the spring member, and when the rotation is completed, the stator coil is excited. When cut, the force of the spring member causes the annular rotor to rapidly reverse due to the restoring force of the spring, and the rotating hammer can hit the ball.

【Example】

 Hereinafter, preferred embodiments of a pachinko launcher apparatus according to the present invention will be described in detail with reference to the drawings. It should be noted that the same or equivalent parts as those of the conventional example are designated by the same reference numerals for description. Reference numeral 30 in FIG. 1 denotes an outer rotor type limited angle torquer having a configuration described later, and a hammer 8 is integrally formed on the outer periphery of the outer rotor type finite angle torquer 30 shown in FIG. It is directly connected to.

The outer rotor type finite angle torquer 30 is configured as shown in FIGS. 2 and 3. That is, what is denoted by reference numeral 1 in FIGS. 2 and 3 is fixed to the fixed shaft body 6 of the fixed cover body 50 having a U-shaped cross section provided on the mounting plate (provided on the pachinko machine side) 2. An annular stator groove 4 formed in the outer periphery of the annular stator 1 has stator coils 4 for excitation wound in a multi-stage array. The fixed cover body 50 is configured to cover a part of the ring-shaped rotor 10.

On the outer side of the pair of bearings 5 provided on the outer periphery of the fixed shaft body 6 in a state of being axially separated from each other, a ring-shaped rotor 10 having an annular shape as a whole is rotated with respect to the fixed shaft body 6. A hammer 8 for hitting a ball for a pachinko machine is directly provided integrally on the outer periphery of the ring-shaped rotor 10. Therefore, the ring-shaped stator 1 is located inside the ring-shaped rotor 10.

As shown in FIGS. 2 and 3, on the outer periphery 1a of the ring-shaped stator 1, three stator teeth 1A whose center-to-center spacing is set to 120 degrees are formed in a protruding manner. On the inner periphery 10a of the rotor 10, the same number of rotor teeth 10A as the stator teeth 1A are formed so as to protrude inward. The ring-shaped rotor 10 is composed of a rotor base 9 directly connected to the bearing 5 and three rotor magnetic bodies 10b attached to the rotor base 9 via bolts 9a. The rotor magnetic body 10b is connected to the rotor magnetic body 10b. The tooth 10A is formed.

A spring member 40 made of a spring is wound around the outer periphery of the ring-shaped rotor 10, and one end 40 a of the spring member 40 is fixed to the ring-shaped rotor 10 and the other end 40 b is fixed. Is fixed to the fixed cover body 50.

Further, the coil 4a of the stator coil 4 is led out to the outside of the fixed cover body 50 through an opening 10D formed in the end wall 10C of the ring-shaped rotor 10, and this opening 10D is The ring-shaped rotor 10 is formed over a predetermined angle so as not to hinder the rotation of the ring-shaped rotor 10 at a predetermined angle (for example, 60 degrees).

Therefore, in the above configuration, when the stator coil 4 is excited, the ring-shaped rotor 10 and the hammer 8 are, for example, 60 degrees only through the magnetic path formed by the stator tooth 1A and the rotor tooth 10A. As the hammer 8 rotates against the spring force of the rotor 40 and the hammer 8 is rotated as described above, the energization of the stator coil 4 is cut off. The hammer 8 can be rapidly rotated to fire a hitting ball (not shown) by the hammer 8.

The effective angle of rotation of the ring-shaped rotor 10 is 60 degrees, which is about half of the angle 120 degrees between the rotor teeth 10A or the stator teeth 1A, and this angle is 60 degrees. Depending on the number of teeth 1A, the number may be one or plural. Further, the rotor teeth 10A can be embedded in the ring-shaped rotor 10 without projecting inward, for example, although not shown.

[0017]

[Effect of device]

 Since the structure of the pachinko launcher according to the present invention is configured as described above, the following effects can be obtained. In other words, since the hammer is directly connected to the outer circumference of the outer rotor type finite angle torquer ring-shaped rotor and the spring member is wound around the outer circumference of the ring-shaped rotor, the overall shape can be made much smaller than before. At the same time, lower prices can be achieved.
