Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball launching device for a pachinko machine.

[0002]

2. Description of the Related Art A conventional ball launching device for a pachinko machine, as shown in FIG. 9, mounts a ball 51 on the rear end of a ball launching rail 50,
The base of the mallet 54 is fixed to the shaft 53 of the rotary solenoid 52, and the ball hitting portion 55 at the tip of the mallet 54 is rotated by a certain angle toward the center of the ball to repeat the ball hitting. A ball launching device is known in which a hammer is rotated by a certain angle or stroked by another means such as a motor or a linear solenoid instead of a rotary solenoid to repeat a hit ball.

[0003]

By the way, in the above-mentioned prior art, it is troublesome to mount the actuator so that the mallet of the actuator exactly matches the center of the ball on the launch rail. Therefore, after mounting the actuator, Although the mallet 54 in FIG. 9 was bent and the position of the mallet tip was adjusted, it was difficult to correctly align it with the center of the ball, and even if it was once aligned, the position would shift due to the secular change of the machine, and the ball would fly. There was a problem that it became unstable. Further, since the mallet 54 is bent by applying an external force with a strong force, the movable piece of the actuator comes into contact with the stator due to damage or distortion of the bearing of the actuator, which causes a failure.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to hold a mallet so as to move toward the center of a sphere placed at the launch position of a launch rail, and the mallet. A mallet mechanism for urging the hammer to the start position and a hammer striking mechanism for repeatedly striking the rear end of the mallet are separately configured and arranged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described in detail with reference to FIGS. Reference numeral 1 is a ball launching rail of a pachinko machine, and one ball 2 is sequentially supplied to a receiving plate 1a at the rear end thereof by a known means. A is a mallet mechanism,
A housing 3 is fixed to a rear portion of the receiving plate 1a, a cylindrical bearing 4 is disposed in the rear portion of the receiving plate 1a, a piston-shaped mallet 5 is slidably rotatably supported, and a collar 6 is provided at an intermediate portion of the housing. 3 is provided with a collar 7 protruding from the rear end, and a spring 8 for urging the mallet 5 backward is mounted between the collar 7 and the housing 3 rear end, and the intermediate collar 6 abuts on the front end of the bearing 4 and The tip is positioned to face the sphere 2. Reference numeral 9 denotes a ball hitting spring mounted on the tip of the mallet 5. B
Is a hammer striking mechanism, in which a rotary solenoid 11 is arranged on an actuator mounting plate 10 and a driving rod 12 has a base of a striking rod 13 fixed thereto. Reference numeral 14 is a striking rod mounting member, and 15 is a rotating member thereof.

Next, the operation will be described. The striking member mounting member 14 is arranged at a predetermined position by rotating the rotating member 15. When the rotary solenoid 11 is turned on, the hammer 13 rotates in the direction of the arrow and strikes the rear end of the mallet 5. The mallet 5 moves forward along the axis of the bearing 4 at a predetermined speed, and the ball launch rail 1
Correctly tap the center of the ball 2 placed on. Therefore sphere 2
Will always be skipped correctly. This operation is repeated.

FIG. 3 shows a second embodiment of the present invention in which the mallet 5 of the mallet mechanism A similar to that of the first embodiment is repeatedly tapped by the linear solenoid 21 of the hammer striking mechanism B.

FIG. 4 shows a third embodiment of the present invention, in which the mallet 5 of the mallet mechanism A similar to that of the first embodiment is repeatedly tapped by the linear solenoid 31 and the link 32 of the hammer striking mechanism B. .

FIG. 5 shows a fourth embodiment of the present invention, in which a mallet 5 of a mallet mechanism A similar to that of the first embodiment comprises a hammer rotating member 43 having four radial cams 42 rotated by a motor 41. The tapping mechanism B is adapted to repeatedly tap.

FIG. 6 shows a fifth embodiment of the present invention. Reference numeral 1 is a ball launching rail, and one ball 2 is sequentially supplied to the receiving plate 1a at the end thereof by a known means. A is a mallet mechanism arranged at the rear of the ball launch rail 1. The outer ring 51 of the ball bearing 50 is fixed to the pachinko machine housing, the middle part of the mallet 54 is fixed to the shaft 53 fixed to the inner ring 52, and The tip of 54 is rotated toward the center of the ball 2 at the firing position. B is a tapping mechanism similar to that of the second embodiment for tapping the lower part of the mallet 54, and may be any mechanism as long as it is a mechanism for repeatedly tapping.

FIG. 7 shows a sixth embodiment of the present invention in which guide grooves 61 are formed on both sides of a mallet 60 of a mallet mechanism A, and guides 62 are slidably fitted in the guide grooves 61.

FIG. 8 shows a seventh embodiment of the present invention, in which a V-shaped guide groove 73 and an upper portion in which a sliding portion 71 having a triangular cross section formed in the lower half of the mallet 70 of the mallet mechanism A is formed in a bearing 72. Guide 74
It is mounted slidably between and.

The housing of the mallet mechanism A may be arranged apart from the rear end of the ball launch rail. In short, the mallet mechanism and the hammer striking mechanism are separately arranged so that only the mallet faces the center of the ball. Any mechanism may be used as long as it is positioned.

[0014]

According to the present invention, a mallet mechanism for holding a mallet so as to move toward the center of a ball placed at the firing position of the firing rail and for urging the mallet to the start position. Since the hammer striking mechanism for repeatedly striking the mallet rear end is separately configured and arranged, it is not necessary to finely adjust the mounting position of the actuator and the position of the striking rod, and the rear end of the mallet separately arranged The mallet always hits the center of the ball at the firing position by just hitting, so the distance, direction, and speed of the hit ball can be made constant. or,
Since there is no influence on the hit ball due to aging of the actuator and mechanical wear, an inexpensive actuator can be used, and the actuator can be separated from the mallet and placed in the empty space of the pachinko machine, so that the overall size can be reduced.
