Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a ball firing device for a pachinko machine that fires a ball by operating a firing punch by driving a rotary solenoid. By making the punch stopper that regulates the vibration of the ball movable, the vibration of the firing punch during standby is reduced and the firing force of the ball is stabilized.

<Prior Art> As a ball launcher for a pachinko machine that operates a launcher by driving a rotary solenoid to launch a ball at a launch position on a guide rail, there is, for example, a ball launcher for a pachinko machine proposed by the applicant of the present invention, as disclosed in Japanese Utility Model Application Publication No. 56-14380. There are some listed.

In the above-mentioned conventional ball launcher, a punch stopper made of rubber or the like is fixed at a standby position remote from the firing position at the lower end of the firing rail, and when the rotary solenoid is not driven, the firing punch is biased by a spring or the like. It is stopped by coming into contact with the punch stopper mentioned above. When firing a ball, the rotary solenoid is intermittently energized to successively fire the balls at the firing position, and the rotary solenoid is demagnetized to catch the firing punch with the punch stopper.

<Problem to be solved by the invention> However, the operation of the firing punch is repeated continuously in a short period of time (for example, 100 times per minute), but the punch stopper made of rubber or the like has elasticity.
When the firing punch hits the punch stopper, the firing punch rebounds and moves slightly, and if the rotary solenoid is energized during the slight movement, it is difficult to stabilize the firing force of the ball hit by the firing punch. In other words, if the rotary solenoid is energized and starts driving the firing punch toward the firing position while the firing punch is making slight movements, the rotation width of the firing punch changes minutely, so the elastic force of the ball is always kept constant. I can't do it. Also,
When the firing punch collides with the punch holder stopper and causes a slight vibration, an unpleasant collision sound is generated, and minute vibrations are transmitted to the back of the player's hand, causing discomfort.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes a rotary solenoid 4 that is connected between a firing position 8 at the lower end of the firing rail 7 and a standby position located rearward from the firing position 8. In the ball launcher 1 for a pachinko machine, the firing punch 5 can be reciprocated by driving, and in the standby position, the firing punch 5 is stopped by a punch holder stopper 10. 5 retreats from the firing position 8 to the standby position, the firing punch 5 first comes into contact with the first
state and a second state in which the firing punch 5 is finally stopped, and the weight member 1
4, the device is always directed toward the first state.

<Operation> The return force of the firing punch is gradually attenuated by the cooperation of the buffer provided on the punch holder stopper and the fluctuation of the punch holder stopper from the first state to the second state, so that the waiting position of the firing punch is always maintained. At the same time, the rotation width becomes the same, the firing force of the batted ball becomes stable, and the slight vibrations are significantly reduced.

<Examples> The present invention will be described in detail below based on examples shown in the drawings.

The ball launcher 1 shown in FIG. 1 has a mounting board 3 fixed to the lower part of the back surface of a picture frame-shaped front frame 2 of a pachinko machine, a rotary solenoid 4 fixed to the front side of the mounting board 3, and a rotary solenoid 4 fixed to the front side of the mounting board 3. A firing punch 5 is fastened with a nut or the like to the output shaft 4' of the tally solenoid 4 protruding from the back side of the solenoid 4, and a springing part 6 provided at the upper end of the firing punch 5 is attached to the surface of a game board (not shown). Face the firing position 8 at the lower end of the slope of the fixed firing rail 7,
On the back side of the mounting board 3, a stop member 9 for regulating the range of rotation of the firing punch 5 and a punch holder stopper 10 are provided.

The above-mentioned stop member 9 is used to prevent the firing punch 5 from moving further when the firing part 6 rushes into the firing position 8 and fires a ball due to the excitation of the rotary solenoid 4, and fixes the rubber or the like. It will be done.

On the other hand, the punch holder stopper 10 stops the firing punch 5, which is retreating by the urging of a spring connected as a return urging means 11, at a predetermined standby position away from the firing position 8 when the rotary solenoid 4 is demagnetized. . Note that the return biasing means 11
may be the weight of the firing punch 5.

The punch stopper 10 shown in FIG.
For example, a vertically long thick plate-shaped punch receiving part 13 has a buffer part 12 formed by fixing a buffering material such as a urethane rubber sheet to the front side where the punch contacts, and the punch receiving part 13 extends obliquely downward from the lower part of the punch receiving part 13. The weight member 14 functions as a biasing means. This punch holder stopper 10 is rotatably attached to the mounting board 3 by a support shaft 15 midway along the length of the punch holder 13, and includes a first stopper 16 and a second stopper 17 protruding from the mounting board 3. The range of rotation around the support shaft 15 is restricted by this.

Therefore, as shown in FIG. 3, the punch holder stopper 10 normally moves the upper end of the punch holder 13 forward to approach the firing position 8 by the bias of the weight member 14, and moves the weight member 14 to the first stopper. It comes to rest in contact with 16. Then, when the firing punch 5 retreats from the firing position 8 due to the return biasing means 11 due to the demagnetization of the rotary solenoid 4, the fourth
As shown in the figure, the upper end of the buffer section 12 first comes into contact with the back surface of the firing punch 5. This state is the first state of the punch stopper 10.

In this first state, the return force of the firing punch 5 due to the return urging means 11 is applied to the weight member 14.
, the firing punch 5 resists the biasing force of the weight member 14 and retreats further.

When the firing punch 5 retreats as described above, the spindle 1
The punch holder stopper 10 supported by the punch holder 5 rotates in a direction in which the upper end of the punch holder 13 is moved backward and the weight member 14 is advanced.
Temporarily attenuates the return force of Then, as shown in FIG. 5, when the weight member 14 comes into contact with the second stopper 17, the punch stopper 10 enters a second state in which it cannot rotate any further, and the firing punch 5 is moved to that position, that is, to a predetermined position. It comes to rest in the standby position. Therefore, the return force of the firing punch 5 is sufficiently weakened by the punch holder stopper 10 before it reaches this standby position, so even if the punch holder stopper 10 hits the second stopper 17 and stops, There will be no rebound due to the recoil. In addition, since the punch stopper 10 does not elastically deform to stop the firing punch 5,
The firing punch 5 is not returned by elastic force.

The most retracted position of the firing punch 5 is the second stopper 1.
Even if 7 is not provided, it is automatically determined by the thickness of the punch receiving portion 13 and the position of the support shaft 15.

In the ball launcher 1 having the above-described configuration, when a player operates the launch operation section 18 on the surface of the front frame 2, the rotary solenoid 4 receives intermittent power supply and is energized. When the rotary solenoid 4 is energized, the firing punch 5, which has been stationary at the standby position, moves forward against the bias of the return biasing means 11 and leaves the punch holder stopper 10. The punch stopper 10 is
When the firing punch 5 leaves, it rotates back due to the bias of the weight member 14, and moves the upper end of the punch receiving part 13 to the firing position 8.
(first state).

On the other hand, since the firing punch 5 continues to accelerate while the rotary solenoid 4 is energized, the firing part 6 at the upper end
By rapidly rushing into the firing position 8, the ball that has been supplied to the firing position 8 in advance is fired, and then comes into contact with the stop member 9 and is stopped. Note that the fired ball moves from the firing rail 7 to the guide rail 19.
The player is guided into the game section on the game board surface and played.

When the firing punch 5 fires a ball, the rotary solenoid 4 is demagnetized, and the firing punch 5 begins to move backward due to the biasing force of the return biasing means 11. Since a hook-shaped rod 20 is provided in the middle of the length of the firing punch 5, when the firing punch 5 retreats, the rod 20 operates the ball supply device 21, and the supply plate 2 on the surface of the frame 2 is
The balls introduced from 2 can be supplied one by one to the firing position 8.

When the firing punch 5 further retreats, the back surface of the firing punch 5 comes into contact with the buffer portion 12 of the punch receiving stopper 10, and the firing punch 5 moves backward while rotating the punch receiving stopper 10. When the punch receiving stopper 10 comes into contact with the second stopper 17 and stops, the firing punch 5 instantly stops at the standby position because the return force of the firing punch 5 by the return biasing means 11 has already been weakened.

When the firing punch 5 is stationary at the standby position, the rotary solenoid 4 is energized again, so that the firing punch 5 rapidly moves forward in the same manner as described above and fires the ball that has been supplied to the firing position 8.

The batted ball firing device 1 repeats the above-described operation in a short period of time, and fires one ball introduced from the supply tray 22 to the game section. The firing force when firing a batted ball is such that the position where the firing pestle 5 starts accelerating forward is aligned at the same standby position every time, and the firing part 6 rushes into the firing position 8 at the same speed every time, so every time the ball is fired. becomes the same strength.

Note that this firing force can be adjusted to a desired strength because the excitation force of the rotary solenoid 4 is changed by varying the resistance value of the variable resistor according to the amount of operation of the firing operation section 18.

In the embodiment described above, the weight member 14 was provided as a biasing means for the punch holder stopper 10, and the rotation range of the punch holder stopper 10 was determined by the first stopper 16 and the second stopper 17, but the punch holder shown in FIG. As in other embodiments of the stopper 10, a spring 23 is provided as a biasing means, and the punch stopper 10
The standby position of the firing punch 5 may be determined by the contact surface of the punch and the position of the support shaft 15.

Further, the punch receiving stopper 10 is not limited to a rotatably pivoted one, and may have any configuration as long as it can temporarily attenuate the return force of the firing punch 5.
For example, in another embodiment of the punch stopper 10 shown in FIG. At the same time, the punch holder stopper 10 is urged toward the firing rail 7 with a force weaker than the return force of the firing punch 5 by a spring 25 as a biasing means, and the punch holder stopper 10 is reciprocated. Move range to 3rd stopper 2
6 and a fourth stopper 27. As shown by the solid line in FIG. 7, the punch receiving stopper 10 normally advances due to the bias of the spring 25 and remains stationary in contact with the third stopper 26 (first state). When retreating from the firing position 8, the firing punch 5 moves backward together with the firing punch 5 due to the return force of the firing punch 5, and as shown by the chain line in FIG. 7, the fourth stopper 27
It comes into contact with and stops (second state). Since the return force of the firing punch 5 is temporarily attenuated when the punch stopper 10 is moved backward against the bias of the spring 25, the firing punch 5 bounces or vibrates when the punch stopper 10 stops. It instantly stops at a predetermined standby position without any movement.

When the rotary solenoid 4 is energized in this state, the firing punch 5 moves forward and separates from the punch holder stopper 10.
5 moves forward and returns to the state where it comes into contact with the third stopper 26 and stops. In addition, guide groove 2
4 may be a straight line, but if it is formed in an arc shape with the rotation center of the firing punch 5, that is, the output shaft 4' of the rotary solenoid 4 as the center, the frictional resistance between the firing punch 5 and the punch receiving stopper 10 is reduced. can do.

<Effects of the Invention> As explained above, according to the present invention, the firing pestle is reciprocated by the drive of the rotary solenoid between the firing position at the lower end of the firing rail and the standby position located further back from the firing position. In the ball launcher for a pachinko machine, the firing punch is stopped by a punch holder stopper in the standby position. The first state in which the punches first come into contact with each other and the second state in which the firing punches are finally stopped can be varied, and the weight member is used to always move the firing punches toward the first state. It can be buffered and stationary at a predetermined standby position. Therefore, the rotation start position of the firing punch by the rotary solenoid is always the same, and the rotation width of the firing punch is also constant.
It is possible to stabilize the launch force of the batted ball, eliminating the so-called uneven flight phenomenon of batted balls, and even if the launch punch operates suddenly and continuously, causing slight vibrations, the punch stopper absorbs it, making it uncomfortable. It is possible to provide a pachinko machine that can withstand playing for a long time, since no collision noise is generated and the player does not feel the impact on his/her hands.
