BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball launching device, and more particularly to a launching device for launching a pachinko ball by tilting a launching punch by a rotational driving force of a driving source, and the operation of the launching device. The present invention relates to a pachinko ball launching device including a ball feeding device that supplies a pachinko ball to a launch position.

[0002]

2. Description of the Related Art Conventionally, a pachinko machine is provided with a launching device for launching a pachinko ball by periodically tilting a launching pestle by a drive cam mounted on a rotary shaft of a drive motor and rotating in one direction. ing.

That is, in this launching device, the launching punch is
The ball projecting portion provided at the upper end is rotatably supported while facing the firing position of the firing rail, and the ball projecting portion is biased by the spring in the direction toward the firing position. Then, the drive cam engages with a passive portion that rotates integrally with the launching pestle, thereby tilting the launching pestle to the rear of the launching position against the biasing force of the spring. At the moment of leaving the passive part, the launching pestle is turned back by the urging force of the spring, and the pachinko ball placed at the launching position is projected by the ball abutting part of the launching pestle that returns and turns. It is configured.

Conventionally, in pachinko machines, for example, Japanese Patent Publication No. 55-13747 and Japanese Patent Publication No.
As described in JP-A-35586, an actuating lever (actuating member) is turned in conjunction with the firing operation of the launching device, and the ball feeding member of the ball feeding device is actuated based on the turning of the actuating lever. By operating, the pachinko balls stored in the prize ball saucer are supplied one by one to the launch position of the launch rail.

Here, as the structure for rotating the actuating lever in conjunction with the firing operation of the launching device, as described in the above publication, a metal wire rod which is in contact with the actuating lever is provided at a predetermined position of the launching punch. There has been put into practical use that is fixed and the metal wire rod causes the actuating lever to rotate in accordance with the rotation angle of the launching punch. Further, in this configuration, the actuating lever rotated by the metal wire actuates the ball feeding member, whereby the pachinko balls are supplied one by one to the launch position of the launch rail in conjunction with the launch operation of the launch device. I am trying to do it.

However, there is a risk that the vibration generated when the launching pestle returns and rotates to launch the pachinko ball is transmitted to the operating lever via the metal wire rod, which may cause the ball feeding member of the ball feeding device to malfunction. is there. As a result, the pachinko ball cannot be appropriately supplied to the launch position, and a stable launch operation cannot be realized.

Further, when the launching pestle returns and rotates (when launching a pachinko ball), the metal wire rod and the operating lever violently contact with each other and wear them, resulting in a deviation of the pachinko ball supply timing. Then, there is also a problem that work for adjusting it is required. In addition, such adjustment work is troublesome because it requires skill and is troublesome.

Further, in the conventional apparatus, since the actuating lever is rotated by the metal wire rod fixed to the launching rod, the metal wire rod moves to the highest point when the launching rod is in the firing position, and conversely fires. When the punch moves to the fully returned position, the metal wire rod moves to the lowest point, and when the metal wire rod reaches the highest point, the pachinko ball to be fired next is supplied. Therefore, the timing for supplying the next pachinko ball onto the launch rail was, of course, just after the launch of the previous pachinko ball. For this reason, when you look into the face from the supply port or when the timing is subtle,
The pachinko ball that was launched sometimes came into contact with the next pachinko ball that looked into the face as it was being fed onto the launch rail, causing uneven flying.

In addition, in the state immediately after the launch, since the projecting portion of the launching pestle is projected forward from the launch position of the pachinko ball on the launch rail, the supply port of the pachinko ball is located far away from the launch position. Must be normal, usually 15mm
It is designed to drop from the front. For this reason, it takes time for the pachinko ball to stop at the firing position, and the pachinko ball may be ejected by the firing punch while bouncing at the firing position, which may cause uneven flying.

Further, immediately after the pachinko ball is fired, the firing pestle oscillates for a while due to the reaction of the collision with the buffer member at the firing position. At this time, the ball point of the launching pestle is protruding to the launching position, so when the next pachinko ball is discharged from the supply port to it, it is bounced back to the jarring point of the launching pestle and on the launch rail. , Will roll once in the firing direction and then come back. For this reason, the pachinko ball may be launched by the launching punch before it firmly stops at the launching position,
Uneven firing occurred and stable firing was not possible.
Therefore, it is necessary to promptly prevent the vibration of the launching pestle, and immediately after the launching, the launching pestle is brought into contact with the cushioning member to control the vibration. However, the shock-absorbing member was severely damaged, and adjustment of the damaged shock-absorbing member was troublesome.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and supplies a pachinko ball to the launch position reliably in association with the launch operation of the launching device to ensure a stable launch operation. It is possible to realize the above-mentioned and yet to facilitate the handling.

[0012]

Means for Solving the Problems, Embodiments of the Invention, and Effects of the Invention In the present invention made to achieve the above-mentioned object, a ball projecting portion provided at an upper end is made to face a firing position of a firing rail. In a state where it is rotatably supported, a launching rod, a biasing member for biasing the launching rod in the direction in which the ball projecting portion is directed toward the launching position, and a unidirectionally mounted rotary shaft of a drive source. A drive cam that rotates, and the drive cam engages and disengages from a passive portion that rotates integrally with the launching pestle, whereby the launching pestle is launched against the biasing force of the biasing member. After tilting backward from the position, the biasing member returns and rotates by the biasing force of the biasing member to launch a pachinko ball placed at the launch position, and a rotating device that interlocks with the launching operation of the launching device. The actuating member to be moved and the ball feeding member are created based on the rotation of the actuating member. By being, the pachinko balls stored in the winning balls pan into firing position of the firing rail 1
In a pachinko ball launching device including a ball supply device that supplies the balls one by one, an auxiliary member that rotates integrally with the rotation shaft is provided at a position separated from the axis of the rotation shaft of the drive source by a predetermined distance. The member and the operating member are connected by a connecting arm, and the rotary motion of the rotary shaft is converted into reciprocating motion to rotate the operating member.

With this configuration, the vibration of the launching punch is not transmitted to the operating member, and it is possible to prevent the ball feeding member of the ball feeding device from malfunctioning. Therefore, it is possible to reliably supply the pachinko ball to the firing position in conjunction with the firing operation of the launching device, and to realize a stable firing operation.

Moreover, since the operating member can be smoothly rotated at a constant speed according to the rotation speed of the rotary shaft, impact wear of each part can be suppressed, and adjustment work after assembling the pachinko machine is possible. Becomes unnecessary. Here, it is preferable that the auxiliary member has a positional relationship with the drive cam so that the drive cam finishes discharging the pachinko ball onto the launch rail after the drive cam starts rotating the launching punch back. By doing so, the pachinko ball to be fired next does not come into contact with the pachinko ball previously fired, and unevenness in flight can be eliminated.

In addition, since the firing pestle is ejected after it starts to return and rotate, it is not ejected by the firing pestle in the launching direction. Therefore, it is not affected by the vibration immediately after the launching of the launching pestle, and it is not necessary to spend time for maintenance of the cushioning member for the launching pestle.

Further, the auxiliary member sets a positional relationship with the drive cam so that the ejection punch finishes discharging the pachinko ball onto the firing rail after retracting from the firing position of the pachinko ball to be fired next. If this is done, the launching pestle will not get in the way when discharging the pachinko ball onto the launching rail. Therefore, the pachinko ball can be discharged from a position closer to the launch position, the rolling time of the pachinko ball on the launch rail can be shortened, and the effect of suppressing the bounce at the launch position can be obtained.

In these cases, when the launching punch retracts the launching position and then discharges the pachinko ball, the pachinko ball receiving operation may be started after the launching punch returns and starts rotating. However, the auxiliary member sets the positional relationship with the drive cam so as to start the operation of supplying the pachinko ball to the launch rail by the ball supply device before the drive cam starts to rotate the firing punch back. Good to do. This makes it possible to set the pachinko ball immediately after the launching pestle retreats from the launching position, and the pachinko ball can be reliably and stably set at the launching position when the launching is performed next time.

In these devices, the connecting portion of the auxiliary member, the connecting arm and the actuating member may be formed of a spherical bearing. This allows the spherical bearing to have a degree of freedom, so that it is easy to install and remove in a narrow space. It should be noted that it is easy to configure the auxiliary member by a crank arm extended from the rotary shaft.

The pachinko ball T placed at the firing position is projected by the ball projecting portion 22a.

After that, by repeating the states of FIG. 2 and FIGS. 10 to 13, the supply of the pachinko ball T to the firing position and the firing of the pachinko ball T are alternately performed. Further, in the launching device 24, the cam piece 80b of the rotating member 80 is repeatedly engaged and disengaged with the roller 78, whereby the launching punch 22 is periodically tilted to launch the pachinko ball T. Then, by rotating the actuating member 34 in conjunction with the firing operation of the launching device 24, the ball supply device 20
The ball feeding member 44 is operated.

When a pachinko ball is launched by the launching pestle 22,
Since the next pachinko ball is still blocked by the blocking portion 44b of the feed member 44, the launched pachinko ball T does not come into contact with the next pachinko ball at the discharge port 26a. Also,
In the embodiment, since the launching punch 22 is retracted from the launching position, the next pachinko ball is dropped onto the launching rail 18, so that the pachinko ball is set at the launching position without touching the launching punch 22. As a result, the following effects are obtained as compared with the conventional case.

First, the conventional situation will be described. In general, the launching pestle 22 vibrates for a while due to the recoil of collision with the buffer member S1 immediately after launching a pachinko ball. For this reason, in the conventional device, the next pachinko ball supplied immediately after being ejected is ejected in the launching direction by the vibration of the launching punch 22 and then returned to the launching position. As a result, it may be fired before it is firmly set in the firing position. Therefore, it is necessary to adjust not only the mounting position of the cushioning member S1 and its adjustment but also periodical replacement of the components during use so that the firing pestle 22 does not continue to vibrate forever.

On the other hand, according to the embodiment, the firing punch 22
The next pachinko ball is not supplied during the vibration of the launching stick 22 and while the launching stick 22 is projecting beyond the launching position. Therefore, it is not necessary to consider the shake immediately after the launching operation of the launching stick 22. Therefore, the labor required for the adjustment and maintenance of the cushioning member S1 can be significantly reduced.

Further, since it is sufficient to drop the pachinko ball after the launching punch 22 retreats, the projecting portion of the launching punch 22 does not interfere and the discharge port 46 is provided in the immediate vicinity of the holding member 32.
a can be provided and can be dropped onto the firing rail 18 from the discharge port 46a. Therefore, the pachinko ball can be brought into contact with the holding member 32 before the pachinko ball rolls largely, and the pachinko ball can be configured to further improve stability without strongly colliding with the holding member 32 and bouncing. it can.

Further, the crank arm 80c and the connecting arm 38
Also, since the connecting portion of the operating member 34 is formed of a spherical bearing, the spherical bearing has a degree of freedom, so that it can be easily attached and detached in a narrow space. Further, since the operating member 34 can be smoothly rotated at a constant speed according to the rotation speed of the rotating shaft 58a, impact wear of each member can be suppressed, and adjustment after the pachinko machine 2 is assembled. No work required.

Besides, various implementations can be made without departing from the spirit of the present invention. For example, the cylindrical portion 80 of the rotating member 80
Although the cam piece 80b and the crank arm 80c are integrally formed in a, the cam piece 80b and the crank arm 80c may be formed separately from the cylindrical portion 80a and then attached to the rotary shaft 58a.

As an auxiliary member, the crank arm 80c
Without connecting, the connecting pin 80d may be directly attached to an appropriate position of the cam piece 80b, or the rotating shaft 58a may be formed into a crank shape and the connecting arm 38 may be connected thereto. Can take various forms.
