Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-striking device for guiding a pachinko ball to a ball-hit position, and to a ball-and-ball game machine for hitting a pachinko ball, such as a pachinko game machine or a metal game machine. The present invention relates to a hit ball supply device used.

[0002]

2. Description of the Related Art Heretofore, a number of hitting ball feeders have been proposed for use in ball game machines, but the applicant of the present invention actually developed a hitting ball feeder which has a particularly simple structure and shape and can be manufactured at low cost. A hit ball supply device (hereinafter referred to as a conventional device) according to Sho 61-16181 was proposed. This conventional device is provided with a longitudinal member that moves up and down in conjunction with the movement of the firing operation position of the batting rod and a firing preparation position, and abutting on the upper end of the longitudinal member. It is provided with a ball feeding member for feeding the pachinko balls at the end of the gutter to the hitting position one by one. Then, this conventional device operates as shown in FIG.

That is, as shown in FIG.
When the ball striking rod 28 is in the firing operation position in which its hammer spring 29 faces the ball striking position 25 of the launch rail 24, the longitudinal member 32 interlocking with the ball striking rod 28 is attached to the rotating member 15 of the ball feeding member 5. It is not in contact, and therefore the rotating member 15 is in a state of being moved downward. In such a state, the pachinko ball P2 at the end of the hitting ball waiting gutter is received above the ball feeding piece 17a formed on the rotating member 15 and in the insertion hole 9a having a width slightly smaller than the diameter of the pachinko ball, The downflow side wall 10 of the insertion hole 9a prevents the pachinko ball P2 from flowing down. Next, the batting rod 28 shifts from the firing operation position to a firing preparation position, that is, a position away from the firing rail 24 (see FIG. 6).
(Transition from the state shown in (A) to the state shown in FIG.
As a result, the longitudinal member 32 interlocking with the ball striking rod 28 moves upward, and accordingly, the ball feed piece 17a of the rotating member 15 also starts to rotate upward, and the pachinko ball P2 is immediately before the ball striking rod 28 reaches the maximum inclination. The upper end of the flow-down side wall 10 of the insertion hole 9a is crossed. Then, the pachinko ball P2 that has crossed the downflow side wall 10 passes through the guide gutter 13 and rolls from the ball outlet 12 to the hitting position 25.

On the other hand, after the pachinko ball P2 reaches the ball exit 12 through the guide trough 13, the hitting rod 28 reaches the maximum inclination, and then rapidly returns to the firing operation position to hit the hitting position 2.
The operation for hitting the pachinko ball P1 in 5 has been completed. In other words, at the hitting position 25, the previous pachinko ball P
After hitting 1, the next pachinko ball P2 arrives and waits. The conventional apparatus continuously repeats the above-mentioned ball feeding operation (usually 100 times per minute).

[0005]

Since the conventional device has the above-mentioned structure and operates, it is provided, for example, on the operation handle arranged on the front surface of the ball game machine.
And when the player stops the operation of the switch for driving the ejection motor (usually a touch switch type in many cases), the ejection motor stops, and at that time, the batting rod 2
It may be just before 8 reaches the maximum gradient. In such a case, the ball feeding piece 17a causes the pachinko ball P2 to exceed the upper end of the downflow side wall 10 of the insertion hole 9a due to the rise of the longitudinal member 32, even though the hitting rod 28 is stopped. The pachinko balls P2 have reached the hitting position 25 from the ball exit 12 through the guide trough 13, and two pachinko balls P2 stay at the hitting position 25 together with the previous pachinko ball P1 (FIG. 6 (C)).
Then, the ball hitting rod 28 hits out these two pachinko balls. The present invention has been made in view of the above circumstances, and an object thereof is to reliably supply one pachinko ball to the hitting position one at a time regardless of the stop position of the hitting rod. An object of the present invention is to provide a hit ball supply device for a ball game machine.

[0006]

In order to achieve the above-mentioned object, in the present invention, a batting ball supply device for guiding the pachinko balls at the end of the batting waiting gutter to the batting position of the launch rail one by one in conjunction with the batting operation. In the ball-striking supply device, the ball-stripping member is provided for sending the pachinko balls at the end of the ball-striking standby gutter to the ball-stripping position one by one in association with the movements of the ball-striking rod in the shooting operation position and the shooting preparation position. The ball feeding member is provided with a support member in which a first insertion hole and a second insertion hole are formed downstream of the first insertion hole, and is supported by the support member and is rotatable up and down. And a rotating member that is rotated in conjunction with the operation of the ball striking rod, the rotating member being retracted into each of the insertion holes when the ball striking rod is in a firing operation position and firing. When in the preparation position, the first ball feeding piece and the When the ball striking piece is formed and the ball striking rod is in the firing operation position, the pachinko ball at the end of the ball striking standby gutter is received by the side wall on the downstream side of the first insertion hole, and the ball striking the ball. When shifting from the operating position to the firing preparation position, the reception by the downstream side wall of the first insertion hole is released and the pachinko ball is allowed to flow down, and the pachinko ball is received by the second ball feeding piece, The second-order pachinko ball was stopped at the position immediately before the side wall on the downstream side of the first insertion hole and at the rear surface of the first ball feed piece, and the ball was returned from the firing preparation position to the firing operation position. At this time, the pachinko ball is guided to the hitting position by canceling the reception by the second ball feeding piece, while the second-order pachinko ball is received by the downstream side wall of the first insertion hole. It is a feature.

[0007]

As a result of adopting the above-mentioned structure, the present invention receives the pachinko ball at the end of the ball striking standby gutter by the side wall on the downstream side of the first insertion hole when the ball striking rod is in the firing operation position, and the ball striking rod is When transitioning from the firing operation position to the launch preparation position,
The pachinko ball is made to flow down by releasing the reception by the side wall on the downstream side of the first insertion hole, the pachinko ball is received by the second ball feeding piece, and the ball is returned from the firing preparation position to the firing operation position. At this time, the receiving by the second ball feeding piece is released and the pachinko ball is guided to the hitting position.

The rotating member 15 is rotatably supported by the shaft pin 21 on the a and 8b. The rear surface of the support member 6 (the surface in contact with the front plate 1) is entirely open, and the inside thereof is formed in a stepped shape. A first insertion hole 9 having a width slightly smaller than the diameter of the pachinko ball is formed in the upper step of the step, and receives the pachinko ball at the terminal exit 3a of the hitting ball waiting gutter 3 flowing down from the exit opening 4 and At the upper end of the side wall 10 (first ball stopper) of the insertion hole 9 in the direction in which the pachinko balls flow down, the pachinko balls are prevented from flowing down. Further, a second insertion hole 11 having a width slightly smaller than the diameter of the pachinko ball is also formed in the step-like lower stage, and a ball outlet 12 is opened in the front. The ball outlet 12 is arranged so as to face immediately before a hitting position 25 of a launch rail 24 described later. Further, an inclined guide gutter 13 is formed so as to connect the upper and lower steps and connects the pachinko balls from the upper to the lower.
Mounting pieces 14a and 14b for fixing the supporting member 6 are formed on both left and right sides of the supporting member 6, and the mounting pieces 14a and 14b are integrally formed with the hitting ball supply tray 2.
And the mounting boss 22a protruding from the outlet opening 4,

The rotating member 15 has a shaft insertion hole 16 at one end thereof.
Is formed, and the shaft insertion hole 16 and the bearing holes 8a and 8b are formed.
And the shaft pin 21 is inserted, and the shaft member 21 is rotatably supported by the support member 6. A first ball feed piece 17 and a second ball feed piece 18 (second ball stopper) respectively corresponding to the first insertion hole 9 and the second insertion hole 11 are provided on the upper end of the other end of the rotating member 15. Part) is integrally projected. The first ball feed piece 17 lifts the pachinko ball stopped in the first insertion hole 9 when it rises, and the downflow side wall 10 thereof.
The upper surface thereof is an inclined surface that faces the downstream side so as to flow down over and over, and the rear surface receives the next pachinko ball at the standby gutter terminal exit 3a. Second
The ball feed piece 18 of the second insertion hole 1 receives the pachinko ball guided by the guide gutter 13 when it is raised.
It is designed to rush in immediately before the downflow side of No. 1 and release the blocking of the pachinko ball when it goes down. Rotating member 15
A weight 19 is fixed to the lower part of the other end of the rotating member 15, and the weight 19 constantly urges the rotating member 15 to rotate downward. Further, a contact portion 20 that abuts a tip end of a longitudinal member 32, which will be described later, is formed below the rotating member 15.
A launch rail 24 is fixed to the lower plate 23 between the ball feeding member 5 configured as described above and the lower plate 23 of the game board (not shown), and the downstream end of the launch rail 24 is bent at a right angle. A hitting position 25 is formed.

On the other hand, a hitting ball launching device 26 is attached to the back surface of a front frame (not shown) of the ball game machine. As shown in FIG. 4, in the hitting ball launching device 26, a hitting rod 28 is rotatably supported on a set substrate 27 having a substantially square shape about a rotary shaft 31. A hammer tip spring 29 is fitted to one end of the hitting rod 28, and the hammer tip spring 29 faces the hitting position 25 of the launch rail 24. Rotating shaft 3
In the vicinity of 1 and on the opposite side of the mallet spring 29, an engagement recess 30 that engages with the longitudinal member 32 is formed. The long member 32 includes two upper and lower engaging pins 36a, each of which has a guide long hole 33 formed substantially in the center thereof and is set on the set substrate 27.
36b is engaged and guided to move up and down.
A rotary roller 34 that engages with the engaging recess 30 is formed at the lower end of the longitudinal member 32 so that the rotational movement of the ball striking rod 28 can be smoothly converted into the vertical movement of the longitudinal member 32. Further, an abutting portion 35 that abuts the contact portion 20 of the rotating member 15 is bent and formed on the upper end of the longitudinal member 32 by a wire having high rigidity.

An operating arm 37 which rotates integrally with the hitting rod 28 is fixed to the other end of the rotary shaft 31 of the hitting rod 28.
An engaging pin 38 that is engaged with and disengages from a cam 40 that is rotated by a motor 39 attached to the set board 27 is formed at the tip of the operating arm 37 so as to project therefrom. In addition to the above-mentioned components, the set board 27 can finely adjust the resilience of the ball hitting rod stopper member 41 (see FIG. 1) and the ball hitting rod 28, as well as the ball hitting machine. Elastic force adjustment mechanisms 42a, 42b provided on the front surface for transmitting the rotation amount of an operation handle (not shown) operated by the player.
(See FIGS. 1 and 4) and the like.

Next, the operation of this embodiment will be described. When the operation handle is operated and the hitting operation is started, the motor 39 starts to rotate, and the cam 40 and the engaging pin 38 are repeatedly engaged and disengaged at a constant speed in accordance with the rotation, and the operating arm 37 and an integral rotation thereof The moving striking rod 28 is reciprocally rotated within a predetermined rotation angle. Then, the cam 40 and the engaging pin 38 start to engage with each other, and the striking rod 28 is launched into the firing operation position (see FIG.
When it is rotated from the position (see (A)) to the firing preparation position, the hitting rod 28 pushes up the lower end portion of the longitudinal member 32. At this time, the engaging recess 30 of the hitting rod 28 and the longitudinal member 32
Since it is in contact with the rotating roller 34, the large frictional force does not act between them, and the longitudinal member 32 is pushed up smoothly.

When the longitudinal member 32 is pushed up, the contact portion 35 and the contact portion 20 of the rotating member 15 come into contact with each other, and the rotating member 15 rotates upward about the shaft pin 21. Therefore, the pachinko ball P2 received by the first insertion hole 9
The first ball feed piece 17 causes the first side ball feed piece 17 to cross over the downflow side wall 10, and is guided to the guide gutter 13 to reach the second insertion hole 11. At this time, since the second ball feeding piece 18 projects into the second insertion hole 11, the pachinko ball P2 is prevented from flowing down to the ball outlet 12 (see FIG. 5 (B)). Therefore, even if the ball striking rod 28 is stopped in a state where the first ball feeding piece 17 has sent out the pachinko ball P2, the ball P2 still has the ball hitting position 2
5, the plurality of balls are not retained at the hitting position 25 even when the hitting rod 28 is stopped at that position as in the conventional case. Further, at the launch preparation position, since the ball pressure of the succeeding ball is not applied to the pachinko ball P2 received by the second ball feeding piece 18, a ball biting state between the ball feeding piece and the pachinko ball does not occur. The malfunction of the rotating member 15 forming the ball feeding member does not occur.

When the engagement state between the cam 40 and the engagement pin 38 is released, the ball striking rod 28 is rapidly returned from the firing preparation position to the firing operation position and is rotated, and is already in the ball striking position. The pachinko ball P1 of
Is guided to the launch rail 24 and launched into the game board.
When the hitting rod 28 returns to the firing operation position, the longitudinal member 32
Moves down under its own weight. Therefore, the rotating member 15 supported by the contact portion 35 of the longitudinal member 32 also rotates downward due to its own weight. Therefore, the pachinko ball P2 that has been received by the second ball feed piece 18 is released from the flow-down prevention state, and rolls to the hitting position 25 via the ball outlet 12. Further, the pachinko ball P3 of the standby gutter terminal exit 3a, which was blocked by the rear surface of the first ball feeding piece 17 at that time, is also released from the blocked state and is received by the first insertion hole 9 (FIG. 5 (C )reference). Since the returning speed of the hitting rod 28 is faster than the returning speed of the rotating member 15, the next pachinko ball P2 always rolls down to the hitting position 25 after the previous pachinko ball P1 is hit. After that, the above operation is repeated.

In the above embodiment, the set board 27 is used.
Since the ball striking rod 28 and the longitudinal member 32 are provided in the above, the relative positional relationship between them is always fixed, and the driving mechanism of the ball striking rod 28 and the longitudinal member 32 driven by the ball striking rod 28 is displaced. Has the advantage of being less likely to occur.

[0018]

As described above in detail, according to the present invention, the pachinko ball at the end of the ball striking standby gutter is received by the side wall on the downstream side of the first insertion hole when the ball striking rod is in the firing operation position, and the ball striking rod is hit. When the shift from the firing operation position to the firing preparation position, the reception by the downstream side wall of the first insertion hole is released and the pachinko ball is allowed to flow down, and the pachinko ball is received by the second ball feeding piece, When the next-most pachinko ball is stopped at the position immediately before the downstream side wall of the first insertion hole and at the rear face of the first ball feeding piece, and when the batting rod returns from the firing preparation position to the firing operation position, The pachinko ball is released to the hitting position by releasing the second ball feeding piece, while the second pachinko ball is moved to the first position.
Since it is received by the downstream side wall of the insertion hole of, the two pachinko balls do not stay at the hitting position and the inconvenience of hitting two pachinko balls at the same time with the hitting rod is eliminated. When the batting rod is in the firing preparation position, the ball pressure of the succeeding ball is not applied to the pachinko ball received by the second ball feeding piece, so the ball feeding member and the pachinko ball are in a ball biting state. This has an excellent effect of not causing the operation failure of the ball feeding member.
