Abstract

PURPOSE:To relax impulse force, which is applied to a pinball machine, by fixing a solenoid, moving a movable member, which is lighter than the solenoid, and using a buffer material. CONSTITUTION:When a solenoid 18 is excited, a plunger 21 is attracted and moved in the hitting direction of a pinball. When the plunger arrives at a stroke end, a head part 19 of the plunger 21 hits a side board 95 of a movable member 83 through a buffer material 36. As a result, the movable member 83 is moved in the same direction as the moving direction of the plunger 21. However, the impulse force at the time of the collision of the movable member 83 to a base frame 23 is relaxed by a buffer material 101. On the other band, when the solenoid 18 is canceled, the plunger 21 is moved in the opposite direction of the above mentioned direction and a ball hitting hammer 20 of the plunger 21 is abutted through a buffer material 36 to the side board 95 of the movable member 83. Then, as a result, the movable member 83 is moved in the opposite direction of the above mentioned direction. However, the impulse force of the movable member 83 to the base frame 23 is relaxed by the buffer material 101.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a firing device for a pachinko machine that shoots pachinko balls thrown into the machine onto a game board.

(Prior Art) The firing device of a pachinko machine is directly operated by a player, and since it directly affects the content of the game, it requires particularly careful adjustment. Either a motor or a solenoid is used as the drive source, and the former transmits the rotational motion of the rotating shaft to the arm via a cam, etc., and the arm moves a batting mallet at the tip of the arm in a linear or arcuate reciprocating manner. , hit a pachinko ball. On the other hand, in the latter, the plunger is attracted by energizing the solenoid, and the attracted plunger moves linearly, thereby hitting the pachinko ball with a hitting mallet provided at one end of the plunger. Therefore, when using a solenoid, unlike when using two motors, there are no inclusions such as cams, and the structure is simple, so the former is easier to handle than the latter. The installation space is small. However, when any of these is used, impact force, noise, and vibration are generated due to the operation of the drive source. In particular, vibration reduces the firing accuracy of the pachinko machine's firing device.

Next, a conventional example of a launching device for a pachinko machine will be described below with reference to FIGS. 19 and 20, using a solenoid as an example. 1 is a pachinko machine equipped with a pachinko machine launcher 2. A game board 3 is provided on the front side of the pachinko machine 1, that is, on the player's side, and a guide rail 4 is attached to the game board 3. The guide rail 4 guides the pachinko balls launched into the device 2 onto the game board 3 from one end, and the other end of the guide rail 4 into which the pachinko balls enter is disposed below the game board 3. In the area surrounded by the guide rail 4 of the game board 3, a winning opening 5 and an out opening 6 are respectively arranged, and the illustration of the obstacle nails is omitted. Reference numeral 7 denotes a glass frame, and the glass frame 7 is attached to the front frame 8 so as to be freely openable and closable, and below it, a front panel 9 is attached to the front frame 8 so that it can be freely opened and closed. A well-known upper tray 10 is provided on the front panel 9, and the game pachinko balls placed in one book 10 are supplied from a supply port 11 to a firing rail 12, which will be described later.

The firing rail 12 is provided at the lower part of the game board 3 and is made of stainless steel. The firing rail 12 is arranged between the other end of the guide rail 4 and the linear solenoids 1 to 18 (described later), and has one end on the solenoid 18 side (hereinafter referred to as "
The input end (hereinafter referred to as the "incidence end") is inclined lower than the other end (hereinafter referred to as the "output end"). For this reason, supply port 1
The pachinko balls supplied from 1 flow down the launch path 13 toward the input end and are guided to the solenoid 18, so that the pachinko balls can be fired by the solenoid 18. In addition, the pachinko ball fired into the solenoid 18,
The light is emitted from the output end and guided to the guide rail 4.

The firing rail 12 has an M-shaped cross-section, and is provided with a firing path 13 for guiding pachinko balls between both ends thereof. The firing path 13 formed in this manner supports the thrown or fired pachinko balls at two points and guides them toward the entrance end or the exit end. The launch path 13 supports the pachinko ball at two points as described above, thereby reducing the coefficient of friction between the two. A locking member 84 is provided on the entrance end (downstream) side, and this locking member 84 is connected to the emission path 1.
3 is engaged with the pachinko ball that has flown down, the flow is stopped and the pachinko ball thrown into the pachinko fil is held at a predetermined position, that is, at the entrance end of the launch path 13.

As shown in FIG. 18, an interlocking rod 14, a pawl member 15, a cam 16, and a sprocket 17 are disposed above the entrance end of the ejection rail 12. These are driven by a solenoid 18, which will be described later, and send out pachinko balls supplied from the supply port 11 to the firing rail 12 one by one. The sending out is synchronized with the pachinko ball firing operation of the solenoid lfl. The claw member 15 and the cam 16 are rotatably supported on the pachinko machine l, and the claw member 15 is attached to one end of the interlocking rod 14.
The interlocking rod 14 has a cam 16 at the other end.
and are rotatably connected, with all pivot axes or axes of rotation disposed parallel to each other.

The solenoid 18 is provided with a plunger 21 having a head 19 formed at one end and a ball hammer 20 at the other end, and a coil-type spring 22 on the head 19 side of the plunger 21.
Or it is tensioned. This spring 22 is the solenoid 18
The plunger 21 attracted by the excitation is returned to its original position during the same demagnetization, and the ball hammer 20
It comes into contact with the casing 35 of the solenoid 18 due to force. Further, 23 is a base frame for attaching the solenoid 18 to the pachinko machine l, and the base frame 23 holds the pachinko balls latched to the locking member 84 and the batting mallet 20 by suction of the plunger 21 based on the excitation of the solenoid 18. and arranged so that they can be collided,
In addition, the head 19 is arranged so as to be able to abut against the cam 16.

The solenoid 18 is energized and demagnetized by operating the operating handle 24, and this energizing and demagnetizing operation is repeated at a rate of about 100 times per minute. The plunger 21 is caused to move linearly by the excitation of the solenoid 18 and the elastic force of the spring 22 during demagnetization. As a result, the plunger 21 hits the pachinko ball that is locked on the locking member 84 using the hitting ball Fii 20, and the hit pachinko ball enters from the other end of the guide rail 4 and is launched from one end onto the game board 3 surface. .

At this time, the cam 16 is caused by the reciprocating linear movement of the head 19.
In order to reciprocate and rotate around the support shaft 25 as shown in the phantom line in FIG. It is rotated back and forth at a predetermined angle about 25. Therefore, the sprocket 17 repeatedly engages and disengages from the pawl member 15.

Reference numeral 27 denotes a guide member, and the guide member 27 is formed with a guide passage (see broken line in FIG. 18) 28 for guiding pachinko balls supplied from the supply port 11 to the launch rail 12. Reference numeral 29 indicates a guide member 27. The upper inlet is located, and 30 indicates the outlet provided at the downstream end. This inlet 29
is arranged directly below the supply port 11 when the front panel 9 is closed, and allows the pachinko balls introduced from the upper tray 10 to flow into the guide passage 28 from the inflow port 29 and then flow down to the launch rail 12 from the outflow port 30. . Further, an insertion hole 31 is formed in the guide member 27, and the sprocket 17 is inserted through the insertion hole 31 and is arranged so as to protrude from the outer periphery of the guide passage 28. Therefore, when the pawl member 15 and the sprocket 17 are engaged, the pachinko ball is locked by the protrusion of the sprocket 17, so the pachinko ball is held in the guide path 2.
The above flow within 8 is blocked.

The interlocking rod 14 is attached to one end or the other end of a spring 32 attached to the pachinko fit, and the splinter 32 rotates the claw member 15 and the cam 16 clockwise around the spindle. is energized. When the above-mentioned engagement is released, the pachinko ball rotates the sprocket 17 counterclockwise in FIG. 18 by its own weight. Further, 33 shown in FIG. 17 is a foul ball gutter located between the other end of the guide rail 4 and the launch rail 12,
Foul balls pass through a foul ball gutter 33 and are collected into a lower tray 34.

In the pachinko machine launcher 2 configured as described above, when the solenoid is excited and demagnetized based on the operation of the operating handle 23, the head 19 of the plunger 21 is moved in response to the linear interlocking, and the cam 16 is interlocked. The rod 14, claw member 15 and cam 16 are operated in sequence. As a result, the pachinko balls thrown into the pachinko machine 1 are supplied one by one to the launch rail 12 at a rate of about 100 shots per minute, and the supplied pachinko balls flow down to the input end side of the launch rail 12. after,
It is locked by the locking th member 84. This locked pachinko ball is hit by the ball hammer 20 of the plunger 21,
The launched pachinko balls enter the other end of the guide rail 4 from the launch rail 12, and are guided from one end of the guide rail 4 to the game board 3. Hereinafter, as mentioned above, the upper plate lO
The pachinko balls thrown in are sequentially launched onto the game board 3.

By the way, when the launching device 2 of the pachinko machine is operating, the solenoid 18 is energized and the spring 22 is activated.
Due to the elastic force, the head 19 and batting mallet 20 of the plunger 21 collide with the casing 35 of the solenoid 18. At this time, the relative position of the pachinko ball locked on the locking member 84 of the firing rail 12 and the ball hitting mallet 20 is strangely changed due to the impact force caused by the impact described above, and both balls are hit by the ball. It is impossible to maintain a constant state. Therefore, in order to suppress the impact force during operation, the conventional pachinko machine launcher 2 has a solenoid 18 installed between the base frame 23 and the pachinko machine 1, and between the impact force with the casing 35 of the head I9. A cushioning material 36 made of an elastic material such as rubber was interposed at this location and attached to the pachinko machine 1.

(Problem to be solved by the invention) However, since the base frame 23 is attached to the pachinko machine via the cushioning material 36 provided with elastic force, the base frame 2] cannot be used to excite and demagnetize the solenoid 18. The impact caused by the collision between the head I9, the batting mallet 20, and the casing 35 at the time! ! ! (vibration) causes it to be moved slightly. In other words, the launcher 2 of a pachinko machine
When the pachinko machine is in operation, the above impact will cause the pachinko machine to
Since the ball itself vibrates, the point at which the ball mallet 20 hits the pachinko ball changes slightly. For this reason, there was a problem in that the hitting condition was not constant and the firing accuracy decreased. Further, such vibrations are transmitted from a part (for example, the operating handle 24) or the entire pachinko machine 1, causing inconveniences such as discomfort to the player.

The present invention has been made in view of this point, and is aimed at solving these problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention fixes the solenoid I8 to the base frame 23, fixes the base frame 23 to the pachinko machine 1, and furthermore, fixes the solenoid I8 to the base frame 23. A member 83 is provided movably along the axial direction of the plunger 21, and the movable member 8
3 is provided with a side plate 95 that can freely come into contact with the head 19 when the solenoid 18 is energized and can come into contact with the ball hammer 20 when the solenoid 18 is demagnetized,
The base frame 23 is provided with a buffer material (buffer cylinder) 101 that buffers the impact caused by the impact of the eight movable members against the base frame 23, and the side plate 95, the head 19 of the plunger 21, and the batted ball F! 120, a cushioning material 36 is provided between each of them.

(Function) With the present invention configured as described above, when the solenoid 18 is energized, the plunger 21 is attracted and moved in the hitting direction of the pachinko ball, and when the stroke end is reached, the head 19 of the plunger 21 is moved. The movable member 83 comes into contact with the side plate 95 of the movable member 83 via the cushioning material 36, and as a result, the movable member 83 moves in the same direction as the moving direction of the plunger 21, or the movable member 83
The impact force at the time of impact on the base frame 23 is buffered by the buffer material 101.

On the other hand, when the solenoid 18 is demagnetized, the plunger 21
moves in the opposite direction to the above-mentioned direction, and the ball hammer 2 of the plunger 21
Either the movable member 83 comes into contact with the side plate 95 of the movable member 83 via the cushioning material 36, and as a result, the movable member 83 moves in the opposite direction to the above, or the impact force of the movable member 83 against the base frame 23 at this time is due to the cushioning material. 101.

That is, the impact force of the plunger 21 on the movable member 83 is absorbed by the cushioning material 36 and by the base frame 23 of the movable member 83.
Since the impact force against is buffered by the buffer material 101,
Noise and impact force during operation of the plunger 21 are prevented. Further, when the plunger 21 is operated, the solenoid 18 is fixed and only the movable member 83, which is lighter than the solenoid 18, is moved, so that the impact force is further reduced.

(Effects of the Invention) As described above, the present invention buffers the impact force of the plunger 21 while moving only the movable member 83, thereby significantly reducing noise and vibration.

Further, after the plunger 21 contacts the eight movable members, it moves together with the movable member 83 while maintaining the contact state, so that only vibration in the direction perpendicular to the axial direction of the plunger 21 is prevented. Pachinko balls are fired accurately along the axial direction.

Furthermore, since the solenoid 18 is fixed and the movable member 83, which is lighter than the solenoid 18, moves, the impact force applied to the pachinko machine 1 is further reduced.

9.99 and the sliding bosses 1.00 and 100 are in contact with each other, and a gap is provided between the inner peripheral surfaces of the buffer cylinders 101 and 101 and the outer peripheral surface of the guide shaft 87. This gap prevents contact between the two members 87 and 101 and improves responsiveness when the movable member 83 slides. In addition,
This gap is maintained by a spacer 105, as shown in FIG.

The side plates 95 and 95 forming the movable member 83 have four escape parts 102 and 103 through which the plunger 21 is inserted.
They are formed in a U-shape, and as shown in FIG. 5, the inner diameters a and b of the relief recesses 102 and 103 are set to be larger than the diameter of the plunger 21 so as not to contact the plunger 21. Therefore, the side plate 95 can freely come into contact with the head 19 when the solenoid 18 is energized, and the side plate g5 disposed opposite to the side plate 95 is provided so as to be able to come into contact with the ball hitting mallet 20 of the plunger 21.

Furthermore, the four relief parts 10 disposed on this head 19 side
The inner diameter a of the plunger 21 is smaller than the outer diameter of the cushioning material 36 installed between the head 19 of the plunger 21 and the side plate 95;
The inner diameter of the escape recess 103 disposed on the ball hammer 20 side is set to be smaller than the outer diameter of the buffer material 36 installed between the plunger 21 and the side plate 95. In addition, relief recess 1
02 and 103 are bored to facilitate attachment and detachment when assembling the solenoid 18 of the base frame 23 and the movable member 83, and the opening cross section is not limited to shapes such as circular or rectangular. , Therefore, during excitation and demagnetization, the buffer materials 36, 36 attached to the plunger 21,
It comes into contact with the periphery of the opening of the four relief portions 102.

The inner diameter of the splinter 22 is set to be slightly larger than the outer diameter of the cushioning material 36 of the plunger 21, and the splinter 22 is interposed between the head 19 of the plunger 21 and the casing 35. Both ends of this splinter 22 are bent, and the bent portions are slightly protruded outward along the axis of the spring 22, as shown in FIG. The other end is inserted and locked into a locking hole 110 bored in a side plate 95 near the head 19 when the movable member 83 is assembled. For this reason,
Both protruding ends of the splinter 22 and the locking hole 109,
The spring 22 is prevented from shifting in the direction perpendicular to the axis of the plunger 21 due to the elastic force applied between both ends, such as the locking of +10, and the spring 22
There is no contact with 1.

On the other hand, the frame plates 88 and 88 of the base frame 23 have insertion recesses 1
04, 104 are formed, and the four insertion parts 104104
The head 19 and the batting mallet 20 are prevented from coming into contact with the frame plates 88 and 88. +06 is a clamping member, the clamping member 106 forms an L-shaped cross section, and the clamping member 106
are screwed onto the mounting plate 91, and the slide piece 98 is slidably held between the four sides of the L-shape and the mounting plate 91 (see FIG. 2).

When using the launching device 2 of a pachinko machine configured in this way, first, as shown in FIG.
1 axis parallel to the extension line on the incident end side of the launch rail 12, and the ball can be hit so that it hits the batted ball PA 20 or a pachinko ball (dashed line part) that is locked to the locking member 84 during excitation, that is, the ball can be hit. to be distributed. At this time, the solenoid 18 is fixed to the two base frames, and the base frame 23 is fixed to the mechanism frame 38, so the pachinko ball locked to the locking member 84 and the batting mallet 20 are always the same. You can set it based on distance. Therefore, if the solenoid 18 is positioned so that the cushioning material 36 hits the side plate 95 of the movable member 83 and absorbs the impact after the pachinko ball is fired, the accuracy of the pachinko ball firing can be improved. I can do it.

Next, after the player has inserted a pachinko ball from the upper tray 10, when the TL player touches the firing handle 66, the control circuit activates the operation of the volume 79, and then sends a control signal ( pulse signal). At the same time, supply port 11. A cam (in this embodiment, it is formed into a bar shape) 16, an interlocking rod 14, a pawl member 15, and a spring 17 supply the pachinko balls thrown from the upper tray 10 one by one to the firing rail 12 and fire them. The pachinko balls supplied to the rail 12 are guided to the entrance end by the inclination of the launch rail 12. Subsequently, the pachinko ball guided to the entrance end is locked by the IL member 84, and the shooting rail 12 and the shooting means 13 are supported at three points at predetermined positions for hitting the ball, and the posture is maintained constant.

After that, the energization and demagnetization of the solenoid 18 are repeated alternately at a rate of about 100 times per minute, and the solenoid 1
When 8 is excited, the franchiser 21 is attracted and moved in the hitting direction of the pachinko ball. Thereafter, when the plunger 21 reaches the stroke end, as shown in FIG.
As a result, the movable member 83 is slid along the operating axis of the plunger 21 using the guide shaft 87 and the slide piece 98 as guides, and the movable member 83 is slid along the operating axis of the plunger 21, and the sliding boss 100 on the head 19 side or the washer 99 and buffer cylinder 101
to be compressed. Due to this.

The impact force of the movable member 83 on the base frame 23 due to the excitation of the solenoid 18 is buffered by the buffer material 101 .

On the other hand, since the plunger 21 is returned to its original position by the spring 22 during demagnetization, the ball hammer 20 is moved to the movable member 8 through the buffer material 36, as shown in FIG.
It hits 3. Therefore, the 01 moving member 83 is slid along the operating axis of the plunger 21 in the direction of the head 19 opposite to that described above, using the guide shaft 87 and the slide piece 98 as guides. As a result, the impact force of the movable member 83 on the base frame Z3 due to the return of the plunger 21 to its original position during demagnetization is buffered by the buffer material 101.

That is, the impact force of the plunger 21 on the movable member 83 is reduced by the buffer material 36 and by the base frame 2 of the movable member 83.
Since the impact force on the plunger 3 is damped by the buffer material 101, noise and impact force generated when the plunger 21 is operated are prevented. Also, when the plunger 21 is activated, the solenoid 18
is fixed and only the movable member 83, which is lighter than the solenoid 18, is moved, so the impact force is further reduced.

When the player's hand is removed from the firing handle 66, the control circuit stops generating the signal controlling the solenoid 18. Note that the adjustment knobs 71 and 71 are not equipped with a device that uses a spring or the like to return them to their original positions, so when the player touches the firing handle 66 again, the previously set batting force is used. Pachinko balls can be launched onto the game board 3. In other words,
Once the adjustment of the adjustment knobs 71 and 71 has been completed, the pachinko ball can be fired just by touching the firing handle 66, so there is no wasted grip strength and no fatigue. Very few.

Note that in this embodiment, the guide shaft 87 provided on the base frame 23 is
1m 87 tubes 101 made of silicone rubber etc.
101 is independently installed for excitation and demagnetization, but the invention is not limited to this, and as shown in FIG.
07 may be provided in place of the buffer cylinders 101 and 101.

In this case, the coil wings 107 , 107 are attached to the guide shaft 87 and stretched between a washer 99 provided on the guide shaft 87 and the outer surface of the side plate 95 of the movable member 83 . As a result, when the solenoid 18 is energized, the movable member 83 is
When it is slid in the axial direction, the washer 99 and side plate 95 are struck vi, mallet Z.

By compressing the side coil springs 107, the impact force is buffered. On the other hand, the impact force caused by the return of the flange 21 to its original position during demagnetization is buffered by the washer 99 and the side plate 95 compressing the coil spring 107 on the head 19 side. In addition, Fig. 16 shows the slice 9 to the slide 1.
8 is not provided.

In the above-mentioned embodiments, the base frame 23 is fixed to the mechanism frame 38 of the pachinko machine 1 with screws, or the base frame 23 is made to protrude from the mechanism frame 38 (that is, the pachinko machine ML). The base frame 23 may be provided with the solenoid 18 and the movable member 83. In this way, by protruding the base frame 23 on the pachinko file side in advance, the positioning work for installing the solenoid 18 and the installation work of the base frame 23 can be reduced to FLFI 1B2S, and the cost of the base frame 23 can be reduced. I can do it.
