Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a batting device for a pachinko machine that uses a plunger type solenoid as a driving source. “A ball hitting device for a pachinko machine using a plunger-type solenoid as a driving source is disclosed in Japanese Patent Application Laid-Open No. 53-42947,
This method is known from Japanese Utility Model Publication No. 49-113786, Japanese Utility Model Publication No. 49-113786, and the like. However, these ball-hitting devices simply replace the motion of the firing part that bounces the ball supplied to the firing position from circular arc movement to linear motion, and when actually implemented, only one ball is hit at the firing position. There is a disadvantage that the connection with the ball supply machine that supplies the balls to the destination is complicated.

The present invention has been proposed in view of the above, and includes a ball feed gear having a plurality of notches into which each ball is fitted, facing in the middle of a ball supply path, and each time the plunger operates, the ball feed gear rotates. By connecting the ratchet mechanism to the plunger of the plunger type solenoid, it is possible to reliably feed each ball to the firing position in conjunction with the operation of the solenoid. The present invention aims to provide a ball hitting device for a pachinko machine that is simple in structure and small in size.

The present invention will be explained below based on embodiments shown in the drawings.

The pachinko machine 1 is provided with a game board 3 so as to cover the frame-shaped front frame λD window from the back side, a game part j surrounded by a guide rail l on the surface of the game board 3, and a game part j surrounded by a guide rail l. In addition to planting numerous obstacle nails (not shown) inside the
..., and a firing rail r is installed in an inclined manner on the surface of the board 70 provided below the game board 3, and a ball hitting device 9 is installed near the lower end of the slope of the firing rail t. The entrance of the foul ball gutter 10 is opened between the slanted upper end of the firing rail r and the inlet of the foul ball gutter 10. Also, front frame 2
A glass frame l/ and a front panel l are hinged to the window part of the window so that they can be opened and closed, and a retaining plate 13 is provided on the surface of the front panel 12.

The firing rail l has a firing position /l formed at the lower end of the slope, and a shallow V groove 7.1 along the length direction on the upper surface, so that the ball hit by the ball hitting device 9 is directed to the guide rail. I will guide you to. In the embodiment shown in the drawings, in order to reliably guide the ball, a horizontal guide/6
In addition to installing the V groove l! An upper guide 17 is provided above the ball with a gap through which a batted ball can pass.

The ball hitting device 9' includes a ball supply path IT which introduces the balls in the supply tray 13 into the firing position 74g while arranging them in a line, and a ball feed gear 19 which controls the flow of balls in the ball supply path II one by one. , a plunger type solenoid 20 that bounces the ball supplied to the firing position/Hiro, and a ratchet mechanism 21 that controls the rotation of the ball feed gear 19 to a predetermined angle in conjunction with the operation of the plunger type solenoid KO. .

The ball supply path /I includes a connection gutter n that is detachably connected to a ball passage port /2' opened on the back side of the front panel 12, and a connection gutter n.
a horizontal U-shaped bending machine n in which the inner ball flows down in a folded manner;
Upper guide 1 that closes the open side of the connection gutter n and the bending machine 3
It consists of a front wall of 7 and the lower end of the open side where the front wall comes off the bending machine is the ball exit 2! It opens toward the groove /j of the launch rail t. According to the embodiment of the drawings, the bending machine 3 has an elongated opening on the outer curved surface.
4 is opened, and a part of the ball feed gear 19 is made to face the ball supply path/inward from the opening 26.

The ball feed gear 19 is a sprukerate-like gear in which a plurality of substantially semicircular notched m cores into which balls fit one by one are formed on the outer periphery. They are freely attracted to each other. When the ball feed gear 19 is placed in the ball supply path Ir, the positions of the tips of the teeth 29 are set so that each ball fits into the notch 27 one by one and flows down. By stopping the rotation of the gear 19, the ball can be prevented from flowing down. In addition, ball feed gear A9
The plunger,
It is synchronized with the type solenoid 20.

As shown in FIG. 1, the plunger type solenoid 20 consists of a cylindrical coil 30, a plunger 31 inserted into the hollow part of the fill 30, and a return spring 32 that biases the plunger 31 in one direction. The re-plunger 31 is advanced by the electromagnetic force generated when 30 is energized,
When the coil 30 is de-energized, the plunger 31 moves back due to the bias of the spring 3λ.
A resilient part 33 made of synthetic rubber or the like is attached to the tip.

To attach such a plunger type solenoid 20 to the board, use a mounting base with a cross-section shape and a support surface of 3 parts! II
A buffer mount 3j made of synthetic rubber or the like is fixed on the top of the soft bridge mount 35, and a plunger type solenoid 0 is fixed on the loose bridge mount 35.
Fix the mounting surface 71 of the mounting base 3hi inside with screws or the like. In this case, the mounting position is set so that the plunger 31 is located on an extension Ij7 obtained by extending vHiz of the firing rail l diagonally downward. The plunger type solenoid 20 fixed in this manner is in a state where the spring 32 is biased to move the spring 33 away from the firing position as shown by the solid line in FIG. 1 when the coil 30 is not energized. When the coil 30 is stationary and the coil 30 is energized, the electromagnetic force generated in the coil 30 causes the plunger 3 to move forward vigorously, causing the first firing part 33 to enter the center of the firing position. . Therefore, the ball located at the firing position/da can be fired with great force. When the energization to the fill 30 is stopped, the resilient part 33 is moved backward by the force of the spring 3 and returns to a position separated from the firing position. Note that due to the back and forth movement of the plunger 31, the solenoid λ0
Even if it vibrates, the buffer mount 3j absorbs this vibration, so that almost no vibration is transmitted to the mounting base J'l or the board 7.

The ratchet mechanism 21 has an upper claw piece 36 and a lower claw piece 37, a rotating claw member 39 rotatably pivoted to a support shaft 3t protruding from the base plate 7, and a rear end of the plunger 3/ A cam piece F/ that is in contact with and rotatably pivoted to a support shaft Q protruding from the base plate 7, and a connecting rod P that connects the upper end of the cam piece 4 (/) and the upper end of the rotating claw member 39. , consisting of a return spring Q, etc., which has one end connected to the shaft attachment part on the side of the rotary claw member 3 of the coupling rod and the other end fixed to the base plate 7, and connects the rotary claw member 39 to the ball feeding gear 19.
The upper claw piece 36 and the lower claw piece 37 are connected to the ball feed gear 19.
The teeth λ are arranged so as to alternately engage with each other.

Therefore, when the solenoid 20 is demagnetized and the resilient part 33 is retracted, the cam piece tIl is pressed against the rear end of the plunger 31, as shown by the solid line in FIG. Stand still in that position. In this state, the teeth λ of the ball feed gear /9 are in contact with the lower end of the upper claw piece 36, so the ball feed gear 19 remains stationary. Therefore, the balls flowing into the ball supply path iz from the supply tray 13 on the front of the Pachinko machine are stopped with the first ball fitted into the notch 27 located in the ball supply path lr. Then, when the plunger type solenoid 20 is energized and the plunger 31 moves forward, the cam piece II/ and the rotating claw member 39 are rotated in the direction shown by the chain line in FIG.
is moved backward and at the same time the lower claw piece 37 is moved forward. When the upper claw piece 36 retreats and comes off the teeth 29, the ball feed gear 19 becomes rotatable and rotates in the direction of the arrow in FIG. 1 due to the weight of the ball in the notch 27. However, in the ball feed gear 19, the lower claw piece 37 is in the front.
'Since it is located within the locus of tooth 29... in 1,
The tooth 29 can only rotate within a range until it comes into contact with the lower claw piece 37. In the embodiment of the drawing, the ball feed gear 19
Six cutout cores are formed at positions displaced by 60 degrees, and the upper claw piece 36 and the lower claw piece are rotated by an angular shift corresponding to half of the notch part λ7 of the ball feed gear 19. 3
7 and set the interval.

Therefore, even if the ball feed gear 19 is allowed to rotate after being disengaged from the upper claw piece 36, it will stop after rotating by about 30 degrees, which is when it hits the inside of the notch 27. When the ball feeding gear 19 rotates approximately 30 degrees, the first ball fitted into the notch 27 comes off the notch core, falls from the ball outlet 2j onto the firing rail l, and is supplied to the firing position/hiro. be done. In this state, the second and subsequent balls are supported by the teeth 29 of the ball feed gear 19 and do not flow down. Furthermore, by the time the ball sent out by the ball feeding gear 19 falls from the ball outlet 2j onto the firing rail l, the firing section 33 has already fired the ball that was at the firing position /II. , firing position from ball exit 2s/41
(The ball flowing down towards , and the shot ball will not collide on the way.

When the firing section 33 finishes firing the ball at the firing position lII, the plunger type solenoid 20 is demagnetized, so the plunger 3/ retreats and the cam piece F/ returns from the chain line state in FIG. 1 to the solid line state. Rotate. When the cam Katahiro/ returns and rotates, the rotating claw member 39 returns and rotates due to the movement of the connecting rod p.
The upper claw piece 36 is moved forward and the lower claw piece 37 is moved backward at the same time.

When the lower pawl piece 37 retreats and disengages from the engaged teeth 29, the ball feed gear 19 rotates due to the pressure of the second and subsequent balls, but when the lower pawl piece 37 rotates approximately 30 degrees, the teeth 29 disengage from the upper pawl piece. It comes into contact with 3≦, so it stops. In this way, even if the ball feed gear 19 rotates approximately 30 degrees due to the retreat of the plunger 31, the second ball will only fit into the next notch 27 and will not flow down onto the firing rail l. There isn't. Then, the plunger type solenoid 20 is energized again to move the plunger 31 forward, and when the springing section 33 springs the ball supplied to the firing position /F, the ball feed gear 19 rotates about 30 degrees in the same way as above. , and supplies the second ball downstream to the firing position lψ. Further, when the plunger type solenoid 20 is demagnetized and the plunger 31 retreats, the ball feed gear /9 further rotates about 30 degrees in the same way as above, and the next ball to be supplied is fitted into the next notch 27. Prepare for the next supply of balls.

In addition, cushioning materials such as urethane rubber tIIIα, lll1
b.

By fixing ullc and l1lld to the rear end of the plunger 31, the contact surface of the cam lug l, and the engaging portions of the upper claw piece 36 and the lower claw piece 37, noise and vibration can be reduced.

As described above, the ratchet mechanism 21 rotates the ball feed gear 19 by an angle corresponding to 27 notches each time the plunger 31 of the plunger type solenoid 20 reciprocates once to bounce a ball, and moves the ball feed gear 19 to the oscillation position. To supply one ball to lψ reliably and in a timely manner.

As described above, the ball striking device N9 supplies the balls in the supply tray 13 to the firing position/l by the rotation of the ball feed gear/l,
A firing section 33 with several balls installed in a plunger type solenoid -〇
It can be fired with more force. Then, the fired ball is moved by the firing rail and the guide rail ψ to the game section! The game club is guided to the upper part of the building, and then hit the obstacle nails and bounced off! Flowing down inside, prize items t are on the way down.
...If you enter it, you will be safe and any winning item 6...
If it flows down the river and enters the out mouth 5 without entering the hole, it becomes an out.

In addition, when operating the operating part 6 provided on the front of the pachinko machine 1, the switch II 7 provided on the operating part 1 is set to 0N-OF.
In addition to starting and stopping the ball hitting device 9 using the F button, you can adjust the amount of current supplied to the plunger type solenoid 20 by appropriately adjusting the Hund p-raq connected to the operating section II6, and control the amount of batted ball. The flight distance can be adjusted as appropriate. Further, by adjusting the number of pulses of the oscillation circuit data, the number of excitations of the plunger type solenoid 20 per unit time, that is, the number of batted balls fired per unit time, can be set to a desired number.

As explained above, according to the present invention, the resilient parts □, 1, □□t, □ are provided at the tip of the plunger of the plunger type solenoid.
2-6゜□□1", and place a ball feed gear with multiple notches into which two balls are fitted, facing the middle of the ball supply path, and each time it operates, the rotation of the ball feed gear is changed from the notch to the ball feed gear. Since the plunger is connected to a ratchet mechanism that allows only an angle corresponding to the angle corresponding to the angle corresponding to The number of parts is significantly smaller than that of the conventional type, and the structure is extremely simple, so it can be easily miniaturized and the assembly work is easy.

Furthermore, since the present invention uses a rectilinearly moving ejecting section to eject the ball, there is no need to precisely align the positional relationship between the ejecting position and the ejecting section, which is different from conventional ball hitting devices in which the ejecting section moves in an arc. It is easier to assemble than.

Note that the present invention is not limited to a pachinko machine in which the game is played by firing balls put into a supply tray, but also applies to a so-called enclosed ball type pachinko machine in which a predetermined number of balls are sealed inside the pachinko machine and these balls are recycled. can be used.
