Description

DETAILED DESCRIPTION OF THE INVENTION Unlike the conventional rotary solenoid system in which the central part is a rotor, the present invention has a magnetic pole generating part that generates a magnetic pole by energizing a coil, which is fixed to a mounting board and used as a stator. A cylindrical rotating body having a magnetic adsorption plate in its body is rotatably fitted on the outside of the stator to form a rotor, and the rotor is provided with an attractive action between the magnetic pole generation part and the magnetic adsorption plate. The ball is hit by rotating the firing rod, and the ball feeding member changes its state by the pressing force caused by the return rotation of the firing rod to prompt the entire ball to wait, and when the above-mentioned suppression is released, the ball feeding portion returns to its original state to produce a waiting ball. This invention relates to an electric ball hitting device for a pachinko machine that supplies balls to a firing position.

A conventional ball hitting device for a pachinko machine using a rotary solenoid rotates a rotor located at the center at a certain angle by the magnetic force of a magnetic pole generator and a coil provided on the outside of the rotor, and this rotational force is used as the output of a four-wheeled rotor. The signal was transmitted to the firing rod through the shaft, and the rapid rotation of the firing rod caused the ball to be hit at the firing position. This kind of configuration requires space in the center for the rotor to rotate, so if you try to increase the number of turns of the excitation coil to increase the generated torque, it will become significantly larger, and the larger the size, the higher the torque. was difficult to obtain.

Furthermore, since the firing rod is connected to the rotating shaft of the rotor, the length of the firing rod becomes long. For this reason, lateral vibration is likely to occur during rotation, resulting in inconveniences such as uneven flight of the ball and unstable flight distance.

Furthermore, since the axis of the firing rod is the fulcrum, the outer periphery of the rotor is the point of force, and the springing part of the firing rod is the point of action, it is difficult to make the fulcrum and the point of force long enough to rotate efficiently. ,
Therefore, a large amount of electric power is required to obtain the desired torque.

In addition, in a ball hitting device that uses intermittent magnetic force to hit a ball, the magnetic force is generated only when the ball is fired, and the weight of the firing rod or a weak spring force is used to return and rotate the firing rod after the ball is fired. Therefore, there is a need for a ball feeder da that operates with such a weak force and does not place a burden on the firing rod when the firing rod is activated.

In history, forcing the ball to be fed into the firing position of the firing rail,
Moreover, if the ball is moved rapidly, the ball supplied to the firing position tends to move wildly, causing uneven flight. In addition, in recent pachinko machines that hit balls continuously at a speed of 100 balls per minute,
Since the ball supply time interval cannot be long, it is important to feed the next ball immediately after the ball at the firing position is fired and to allow time for the ball to settle down at the firing position to prevent the supplied balls from going wild and eliminate uneven flight. is required.

The present invention has been proposed in view of the above, and includes a stator in which a magnetic pole generating part that becomes a magnetic pole when a coil is energized is fixed to a mounting board, and a cylindrical rotor rotatably fitted on the outside of the stator. A magnetic adsorption plate is provided on the body corresponding to the outer peripheral end of the magnetic pole generating part to serve as a rotator, and a firing rod is fixedly provided on the rotor, and the firing rod is located at the firing position at the base end of the firing rail. A ball feeding member is mechanically attached to the firing rod, which changes the state by the pressing force when restoring to the first state where it is separated from the ball and puts it on standby, and sends out the waiting method by the restoring force when the pressing force is released. By associating it with the ball, it is possible to efficiently obtain a large hitting force with a small size and light weight, and moreover, it is possible to feed the ball to the firing position immediately after the firing rod hits the ball.
This aims to provide an electric ball hitting device for a pachinko machine that can stabilize the firing direction and flight distance of a ball.

In order to fix such a coil band and magnetic pole generating section 7 to the mounting board 3, the boss io of the magnetic pole generating section 7 is fixed.

A fixed shaft D is fitted into the inside of the fixed shaft D, and an adjustment spacer /7 is screwed into a male threaded portion /6 formed at one end of the fixed shaft D. Then, the tip of the male threaded part/B is inserted into the shaft hole 7g of the mounting board 3, and a tightening nut/9 is screwed onto the tip of the male threaded part/6 protruding from the mounting board 3 to fix it. In the illustrated embodiment, the fixed shaft 3 is passed through the magnetic pole generating section 7, but independent shafts may be provided on both sides of the magnetic pole generating section 7, and the fixed shaft 3 may be fixed by these shafts.

The rotor 5, which rotates along the outer circumferential surface of the stator group formed as described above, encloses the stator group on the outside of the stator group, so that the cylindrical rotating body 20 can be freely rotated. A magnetic adsorption plate is disposed on the body of the rotating body -0 in correspondence with the portion that becomes the magnetic pole of the magnetic N5 generative portion 7, that is, the end portions facing each other on the outer circumferential side. In the illustrated embodiment, a disk 2.2.22' having a diameter slightly larger than that of the magnetic pole generation part 7 is attached to a fixed shaft protruding from both sides of the magnetic tooth generation part. The two disks 2.2. Three magnetic adsorption plates made of magnetic material such as iron are spaced apart from the outer periphery of Yuko'.

They are installed at 120 degree intervals in accordance with the above, and fixed with screws, 2S, etc., and the remaining parts are covered with protective side plates made of non-magnetic material such as synthetic resin, 26α, t, h, uc with screws, 25 A cylindrical rotary body θ is configured, which is fixedly attached to the stator by the stator, etc., and can contain the stator and rotate concentrically with the stator.

Note that it is desirable that the distance between the inner surfaces of the magnetic adsorption plates 2'lα, col llb, and 2g C and the outer surface of the magnetic pole generating portion 7 be close enough that they do not come into contact with each other.

In addition, in the illustrated embodiment, the magnetic adsorption plate 2'la

In Fig. 2, the hole is an arc-shaped long hole opened in the disk core a, and is used to pass the conductor g' of the coil g passed through the conductor take-out hole 2g opened in the magnetic pole generating part 7. It is a hole and has an appropriate length that does not cause any trouble even when the rotary hitter S rotates. Instead of opening this elongated hole 27, a notch may be provided.

The firing rod 6 that shoots the ball has a resilient part t' made of an elastic body at its upper end, and its base end is fixed to the rotator 5 so that it rotates integrally with the rotor 5. .

In the illustrated embodiment, the proximal end of the firing rod is fixed to the disk 22 on the mounting board 3 side with screws 25', but it may be formed integrally with one of the magnetic adsorption plates, for example, Koku α. The entire body may be L-shaped, with the vertical part of the L-shape serving as a firing rod and the horizontal part serving as a suction plate, 21Iα. When integrally molded with the suction plate cog in this manner, both can be attached and detached by one operation.

That is, the left and right ends of the suction plate 21I are circular plates, 2.2. ．． 2.
By screwing 2', the firing rod 6 can be firmly fixed.

In this way, the firing rod in the present invention is a cylindrical rotating body, 20
Since it is fixed to the output shaft of a conventional rotary solenoid, the length can be made shorter than that of a conventional rotary solenoid fixed to the output shaft. Therefore, lateral vibration during rotation can be extremely reduced, and defective firing caused by lateral vibration can be eliminated. In addition, since the torque of the rotator S can be efficiently applied to the firing rod t, in other words, the point of force can be brought closer to the # firing part 2', which is the point of application, so that the same strength can be achieved by the principle of leverage. Even with a magnetic force of

To attach the ball striking device W/ constructed as described above to a pachinko machine, as shown in FIG.
Place the mounting board 3 at a predetermined position on the back side of the front frame so that it enters the firing position 30 at the base end of the guide rail 29 attached to the game board, and fix it with screws Jj'' etc. To adjust the firing part 6' to enter the center of the firing position 30, adjust the distance between the mounting board 3 and the left rotator by appropriately rotating the adjusting spacer/7 and nut/2 on the fixed shaft. and adjust the position of the firing rod.

The rotation angle of the firing rod 6 is such that the firing portion 6' of the firing rod 6 is fired 4 inches from the firing position τp (solid line in Figure 4), which is waiting at a distance backward from the firing position 30, with the fixed l1lI9 as the center. place g
Approximately 6 to the ball launch position (Fig. 4) that enters 13o
A degree of D is good. The rotation angle of this firing rod is
It is regulated by stoppers 3/α and 31b installed above.

In order to make the firing rod 6 reciprocate between the firing preparation position and the batting ball firing position, when the firing rod 6 is located at the batting ball firing position, the end of the magnetic pole generating part 7 of the stator rod /, 2(t', /21)'... and a suction plate provided correspondingly, 211α, atib, , 2
The magnetic pole generation W, 7th place 1σ and the adsorption plate 2da α, 2 are set in advance so that the center line of the magnetic pole coincides with the radial line from the fixed axis.
11b, Adjust the position with cog C. Further, at the firing position, the firing rod 6 is stopped in a slightly extended rearward state. Note that when the firing rod 6 is in the first state in the firing preparation position, the end of the magnetic pole generator 7 and the suction plate are partially overlapped, and the firing rod 6 rotates to fire the bullet. In the second state in which the ball is hit at a certain position, it is desirable that the end of the magnetic pole generating section 7 and the suction plate cog overlap as widely as possible.

Next, the operation of the ball hitting device will be explained.

The player can use the operation section 3 provided at the lower part of the front side of the pachinko comb.
When the rotatable operating lever 3.2' of λ is rotated, the activation switch 3.7 provided inside the operating section 32 is turned to OH.
A control circuit that controls the rotation of the firing rod 6? A pulse of a constant width is supplied to the coil connected through the lead wire, and the coil is momentarily excited. As a result, the magnetic pole generating section 7 is magnetized, and each magnetic pole generating piece (L,
Each end of /ah, /λC... α, '12b'
, 1.2c', . . . , magnetic poles are generated, respectively. For example, if the adjusting spacer/7 side of the stator is the N pole, the other end is the S
It becomes a pole, and the magnetic flux coming out from the N pole is the magnetic pole generating piece /2α, /,

S poles are formed at /2g', /2f', respectively.

Therefore, magnetic pole generating piece/2α end/co α′, (N pole)

24th, 24tt" are instantaneously attracted. The rotating element S rotates due to the attraction force of this magnetic force, and the firing rod t rapidly rotates from the firing preparation position to the batted ball firing position and reaches the firing position 30. The balls are sold for sale.Instead of providing a microswitch as the starting switch 33, a so-called touch switch circuit that turns on when the player touches the operating section may be used.

When the firing rod A rotates to the ball firing position, the pulse power supply to the coil g disappears and the fill is demagnetized. + /
The magnetic field of 2b'... disappears. For this reason, the firing rod is
It rotates back due to the reaction of the bullet and its own weight, returning to the firing preparation position. In addition, in order to ensure that the firing rod 6 returns to its original position and to make the next shot stable, the firing rod 6 may be slightly biased toward the firing preparation position using a weak spring or the like.

Then, when the next pulse is supplied to the coil g, the magnetic pole generating section is excited again. By repeating this,
Balls are fired intermittently.

The flight distance of the batted ball can be adjusted using the operating lever 3 of the operating section 32.
Variable resistor 3 installed at the tip of the shaft rotated by
By adjusting the resistance value of S, the power amplifier circuit 3 in the control circuit 3
This is done by adjusting the power to the coil g using A. That is, the more the operating lever 3.2' is rotated, the stronger the electric power applied to the coil g becomes.
, /, 2c... and suction plate 21α, , 24th
, 2 The attraction force between the rotor S and the rotor S is strengthened, and the torque of the rotator S is increased to powerfully hit the ball, thereby extending the flight distance of the ball.

In this way, the ball-hitting device can hit the balls supplied to the firing position 30 one after another.

And the empty launch position 30. The ball supply mechanism supplies balls one by one in synchronization with the firing motion of the firing rod.

When balls are thrown into the saucer 37 provided on the front side of the pachinko machine, the core balls are aligned in a line by the ball outlet gutter 3g extending from the inclined lower end of the saucer 37, and flow from the inlet 039 of the front panel to the back side of the panel. You will be guided. The slanted lower end portion of the ball outlet gutter 3g communicates with the outlet aO which is opened near the firing position 30 of the firing rail knob. A ball feeding member is provided in the flow path of the ball outlet gutter 3g located upstream of the outlet qo. The ball feeding member 3 is converted into the 3
This controls the flow of the ball within g. Figures 6 to 8
The embodiment of the ball feeding member lI/ shown in the figure has a flow prevention part l12 projecting laterally above the negative side, a shelf-shaped sludge receiving part 3 below the flow prevention part, and other parts. By rotatably pivoting the upper part of the side part, the flow stopper goo can move forward and backward into the flow path of the ball outlet gutter 3g, and the slag receiving part 11. ? It faces upstream of the delivery lock θ so that it can be raised and lowered. And this ball feeding member da/ is always moved by its own weight to the flow stopping part 1.
1.2 is lowered into the flow path of the ball outlet gutter 3g and stopped. Therefore, the first ball that has flown down from the saucer 37 is prevented from flowing down by the flow stopper 4'J and is stopped. Below the ball feeding member l/, there is an inverted-shaped feeding arm l/ having a substantially horizontal protrusion/l that abuts the lower end of the ball feeding member l/.
, are rotatably pivoted, and a hook-shaped rod 6 provided on the firing rod is detachably abutted on the front surface of the subordinate portion q7 of the feed arm IIS. Therefore, when the firing rod slowly returns and rotates from the firing position to the firing preparation position due to its own weight, that is, when it converts to the first state, the rod l16 presses the feed arm lIs and moves backward as shown by the solid line in Fig. 7. times 7
jjt+. When the left side of the feed arm rotates rearward, it rotates so as to push up the ball feed member, so that the flow stopper 9.2 retreats upward and is removed from the first ball. Therefore, the first ball rests on the slag receiver 3. The upper edge portion of the delivery date 0 faces the ball supply regulating portion g on the ejection rail side of the slag receiving portion g.

Therefore, in the first portion where the slag receiver gl13 has been raised, the ball sending member l/ makes the balls on the slag receiver 1g 3 come into contact with the supply regulating portions lI, r and wait. Soul shooting A in this state
rapidly rotates toward the firing position 3o, and the rod cross separates from the feed arm aS as shown by line fIjL'4 in Figure 7. In other words, the firing rod 6 changes to the second state and the feed arm Q& When released, the feed arms f, ll- move rod +! due to their own weight. From t, take the crab and turn it back, and lower the protruding puffer fish. When the slag receiving part 3 descends, the ball sending part d/ is rotated back in the direction of lowering the slag receiving part 3 due to its own weight and the weight of the first ball, and the state is changed to the second state. When the sphere descends by restoring the ball feeder 4'/ to the second state p like a mouth, the nuclear sphere is released from the supply regulating part at the upper edge of the delivery 0daO, so It passes through the delivery line 0g θ, falls onto the firing rail side, and is supplied to the firing position 30. Note that when the slag receiving part lI3 descends, the flow stopping part 11.7. Since the ball also descends as one, the next ball is prevented from flowing down by this flow stopping part Guko and stops. When the firing rod 6 returns to the first state of the firing preparation position 30, the rod 'IA presses the feeding arm 3 and rotates the ball feeding member ll/.
Similarly to the above, the ball released from the flow stopping part l12 waits on the slag receiving part DA3. By repeating this process, one ball is supplied to the firing position 30 each time the rod 6 performs a firing operation.

In addition, in the above-mentioned ball supply operation, there is no need for a driving force to raise the ball, and the member that prevents the ball from flowing down is simply advanced and retreated, so the weak force when the firing rod 6 returns due to its own weight is reduced. However, it can be operated easily.

In addition, when the firing rod t performs firing operation, the feed arm ll'
Since t is only released, the driving force of the rotating element S can be effectively used as the elastic force of the ball without wasting it.

Furthermore, the firing operation in which the firing rod 6 rapidly rotates from the firing preparation position toward the firing position, and the ball feeding member da/
The ball feeding operation, in which the ball is rotated after being released from the pressure of Progress is slow. Therefore, it is possible to take an appropriate time delay before actually supplying the ball, and it is possible to avoid collision between the shot ball fired by the firing rod 6 and the supplied ball. However, since the ball can be fed immediately after the firing rod A is fired, it is possible to take a longer time for the ball to settle at the firing position 30 than in the conventional ball feeding mechanism. Therefore, it is possible to stabilize the collision state between the ball and the springing portion 6' of the firing rod 6, and it is possible to stabilize the firing direction and flight distance of the ball.

9 to 12 show other embodiments of the ball supply mechanism.

The ball supply mechanism shown in FIGS. 9 and 10 has an upright supply regulating portion rim' formed at the tip of a horizontally long ball feeding member l/' whose base end is rotatably pivoted by a shaft getter α. At the same time, the upper surface of the supply regulating section lIg' is located on the shaft attachment base end side.
A flow stopping part I1.2' is formed with a slight downward slope toward Ig', and the flow stopping part I1.2' and supply regulating part y-g' are connected to the bottom opening at the inclined lower end of the ball outlet gutter 3g. A slag receiving part l13' is fixedly provided at a position slightly higher than the bottom surface of the ball outlet gutter 3g within the interval between the flow stopping part Q' and the supply regulating part Daz'. be.

An inverted-shaped feed arm 5' is rotatably pivoted below the tip of the ball feed member 3', and the hanging portion 5' of the feed arm 3' faces the rod 2 of the firing rod. Let it happen. When the rod lI6 is detached from the feeding arm 3', as shown in FIG. ' and the supply regulating part lIg' are lowered and withdrawn from the ball guiding gutter 3. Therefore, the tip of the ball that has flowed down from the tray 37 comes into contact with the side surface of the slag receiving portion lI3' on the flow stopper side, and is stopped on the flow stopper 11.2'.

In this state, the firing rod rotates gently toward the firing preparation position due to its own weight, and Rondo'iA moves to the feed arm lI! When the hanging part '77' of ' is pressed backward, that is, when the firing rod 6 is pressed in the middle of restoring to the first state, the feed arm lI
5' is a sideways armrest as shown in Figure 9! Rotate r/ in the upward direction. When the arm rod 5/ rises, the ball feeder part/
' is raised, the flow stopper 11.2' slowly lifts the foremost ball and sends it onto the slag receiver 413'.

The balls sent onto the slag receiving part 43' in this way are
It is prevented from flowing down by the supply regulating part y' that closes the ejection rail side of the slag 13', and waits on the slag receiving part lI3'.

In addition, in this state, that is, the first state of the firing rod, the flow stopper lIλ' enters the ball guide gutter 3g from below, so the balls in the ball guide gutter 3g flow down into the flow stopper g'. be prevented and stopped.

Then, when the firing rod 6 rapidly rotates and changes to the second state, the ron'It separates from the feed arm 3' as shown by the chain line in FIG. 9, releasing the feed arm lI3'. When this state is reached, the feed arm l' moves the way provided at the tip of the arm rod /) by the bias of the left Ob. 1 is returned and rotated in the direction of lowering, and the tip portion of the ball feeding member 1I/' is lowered. The tip of the ball feeding member 4 (/') moves down and the flow stopper 1' retreats from the ball outlet gutter 3, and the supply regulating parts t and tg' move down to the top of the slag receiving part ll?' When the ball is released, the ball on the slag receiving part lI3' rolls and the sending log O
The tip of the ball that fell from the ball onto the launch rail 2q and was supplied to the launch position 30 and stopped within the ball guide gutter 3g flows down and reaches the slag receiver 4 ( ,?'
It hits and stops.

In this way, the ball supply mechanism shown in FIGS. 9 and 10 uses the weak force when the firing rod 6 changes to the first firing state to feed the slag receiver 4t.
3', one ball at a time, relatively slowly, and when the firing rod 6 changes to the second state, the feeding arm is released! By simply releasing the pressure of ', the balls on the slag receiver 4t3' can be allowed to flow down naturally and be supplied to the firing position 3o without putting any burden on the firing rod.

Further, the firing operation of the firing rod 2 and the supplying operation of the ball feeding member 4'/' are started at the same time, but the ball feeding operation is performed when the ball feeding member lI/' is released from the pressing of the firing rod 6. way)
Since the ball is rotated to its original state by the biasing force 30α, the ball supply timing can be slightly delayed compared to the time of sale. Therefore, not only can it be possible to prevent the ball from colliding with the supplied ball, but also the ball can be supplied to the firing position 30 in a timely manner immediately after the ball is fired, and the time required for the ball to settle down can be extended. .

This stabilizes the direction and flight distance of the ball.

Another embodiment of the ball supply mechanism shown in FIGS. 11 and 12 has a slag receiving portion 3' whose upper surface is slightly sloped downward toward the outlet 10 at one end and a way at the other end. A ball feeding member g/' having Ar0c and rotatably pivoted by a shaft getter b in the middle of its length is provided at the inclined lower end of the ball guiding gutter 3g, and is rotated below the ball feeding member 4t/'. An arm piece of the inverted-shaped feed arm llS' that is freely pivoted! r2 to the above way) kO
c is viewed from below, with the feed arm llt' facing the rod dog 6 of the firing rod. When the rod 6 is detached from the feed arm 3', the ball feed member member /' is in the way (way) SO as shown in FIG.
The slag receiving portion J' is raised by the bias of C, and the slag receiving portion 3'
The flow control part 11.2" formed at the tip of the ball outlet gutter 3g
facing into the flow path. Therefore, the tip of the ball that has flowed down from the saucer 37 is the tip of the slag receiving portion lI3', which is located at the tip flow stopper y, 2#.
It comes into contact with and stops.

The launch lever rotates gently toward the launch preparation position due to its own weight, and the rondo lIA moves to the hanging part of the feed arm lI7.
When ' is pressed, that is, when the firing arm changes to the first state, the feed arm ll! rotates the arm SS in the upward direction as shown in FIG. When the arm piece S2 rises, it lifts the SOC (Way), so the flow stopper l1 at the other end
2' and the slag receiving part 3' descend, and the first ball reaches the slag receiving part l1.
It rests on 3'. A delivery port 0 is opened on the discharge rail side of the slag receiving portion 3″, and the lower edge of the delivery port 11O is connected to the supply regulating portion t.
Functions as tg'. Therefore, the balls on the slag receiving portion 3' are stopped from flowing down by the lower edge of the outlet yo.

Then, when the firing rod suddenly rotates and changes to the second state, the rod lIA separates from the feed arm K' as shown by the chain line in Fig. 11, releasing the feed arm 1''. ' returns and rotates due to its own weight, and the ball feeding material 1li- moves)! Due to the bias of the SOC, several balls are restored and rotated in the upward direction with the balls placed on the slag receiver l13'. When the feed member tag /' rotates in this way, the ball on the slag receiving part lI3' moves into the supply regulating part ag'.
Since it is located higher than the supply regulating portion l1g', it falls from the delivery log 0 onto the firing rail 29 and is supplied to the firing position 30. Moreover, when the slag receiving part 13' rises, the flow stopping part lI at the tip! ' enters the ball outlet gutter 3g, so the balls in this gutter 3g are prevented from flowing down by the flow-down stopper 11.2'.

In this manner, the feeding mechanism shown in FIGS. 11 and 12 rotates the ball feeding member +/' in a state in which the weight of the ball is not absorbed when the firing rod 6 changes to the first state. It can be sufficiently driven by the weak force of the firing rod. In addition, when the firing rod changes to the second state, the ball is relatively gently lifted and fed by the bias of the ball feeding member (way) kOc, so all the rotational force of the firing rod is transferred to the ball. Can be used as a projectile force.

Furthermore, the firing operation of the firing rod 6 and the ball supplying operation of the ball feeding member ll/' start simultaneously, and immediately after the firing rod 6 has fired the ball, the next ball is fed to the firing position 30. Because you can
You can fully explore the time it takes for the ball to settle down.

Therefore, the launch direction and flight distance of the ball can be stabilized.

As explained above, according to the present invention, the magnetic pole generating part that becomes a magnetic pole when the fill is energized is fixed to the mounting board to form a stator, and the cylindrical rotating body is rotatably fitted on the outside of the stator. A magnetic adsorption plate is provided corresponding to the outer circumferential end of the magnetic pole generating part to serve as a rotator, and a firing rod is fixedly provided on the rotor, and the firing rod is moved from the firing position at the base end of the firing rail. A ball sending member is mechanically attached to the firing rod, which changes the state by the pressing force when restoring to the first state of separation and puts the ball on standby, and sends out the waiting ball by the restoring force when the pressing force is released. By linking, it is possible to efficiently obtain a large pushing force with a small and light boat, and moreover, the ball can be fed to the firing position by the restoring operation of the ball feeding member immediately after the firing rod lights up. The swing of the ball can be ensured, the firing direction and flight distance of the batted ball can be stabilized, and the ball feeding operation can be performed in a timely manner even if the return rotational force of the firing rod is weak.

In the above embodiments, a weight is provided as a means for biasing the ball feeding member, and the ball feeding member is pivoted at a position away from the center of gravity, but it may be biased by a spring or the like.
