Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a winning ball extraction device for a pachinko machine that arbitrarily extracts winning balls remaining in a collecting gutter and a guide gutter extending from the collecting gutter to the outside of the machine. .

(Prior art and its problems) Recent pachinko machines are equipped with a large number of prize winning devices and large winning devices, and for example, when a special prize mode is formed during a game, the large winning device remains open for a long time. ,
The mechanism is such that a large amount of winning balls are generated in a short period of time.

Furthermore, in the final stage of the manufacturing process for pachinko machines, there is a function check called ``dama-tsu'', in which balls are inserted into each winning device and large winning device, and the operation of ejecting the winning balls is checked. is necessary.

Furthermore, when installing a pachinko machine in a gaming parlor, inspection work using a "ball toss" is required as described above, and during such work, a large amount of winning balls accumulates in the collection gutter and guide gutter.

Conventionally, in order to discharge the winning balls out of the machine, the winning balls had to be extracted through a regular route, and the winning balls were delivered one by one while the worker had to manually operate the winning ball ejection mechanism. It was being discharged.

Furthermore, when a so-called "stoppage" occurs in a pachinko machine during operation of a game parlor, the prize ball tank becomes empty, making it impossible to play, and the function of the prize ball discharging mechanism also stops.

As a result, a large amount of winning balls remained in the collection gutter and guide gutter, and when canceling the stoppage, the staff manually activated the prize ball ejection mechanism as described above, and sequentially delivered the winning balls one by one. It was ejected from the aircraft through the official route.

As described above, conventional pachinko machines have had a problem in that it takes a lot of time and effort to remove winning balls remaining in the collection gutter and guide gutter from the machine.

The present invention was made to solve this problem, and the remaining prize balls in the collection gutter and guide gutter can be quickly and easily removed from the machine from the middle of the guide gutter without passing through the prize ball ejection mechanism by external operation. The purpose of this invention is to provide a winning ball extracting device that extracts winning balls.

(Means for solving the problem) The winning ball extraction device for a pachinko machine according to the present invention has the following features:
It is in the middle of the guide gutter 10 disposed between the collecting gutter 17 that collects winning balls and the winning ball processing means 13 that takes in one winning ball, and the above-mentioned winning ball processing means 1.
The guide gutter 10 is connected to the prize ball detection device 28 that detects the presence or absence of prize balls stored in the prize ball tank 2 at a position spaced apart from the prize ball tank 2 by approximately a predetermined number of winning balls.
an opening 41 comprising a blocking member 37 for opening and closing the passage 18, and an opening/closing door 42 through which winning balls stored upstream of the guide gutter 10 from the blocking member 37 flow out;
When the prize ball tank 2 becomes empty, the blocking member 37 closes the passage 18 to prevent the winning balls from flowing down, and the opening/closing door 42 is opened by external operation to open the opening 41. Blocking member 37 in the guide trough 10
It is configured so that winning balls remaining on the more upstream side are pulled out of the machine.

(Example) Hereinafter, the present invention will be explained based on drawings showing an example of implementation.

First, referring to FIG. 1, the prize ball ejection mechanism will be explained.

The prize balls in the prize ball tank 2 provided on the upper part of the back mechanism panel 1 pass through the outlet gutter 4 which properly rectifies the prize balls and guides them to the Tamazaya case 3, and then into the Tamazaya case 3 where a predetermined number of winning balls are stored. satisfy.

The ball case 3, which is provided so as to be tiltable, is tilted for ejection in response to the drive of the prize ball ejection drive device 5.
It is interlocked with a prize ball ejection drive device 5 via a link mechanism 6, and every time the prize ball ejection drive device 5 processes one winning ball, it tilts and discharges a predetermined number of prize balls into the gutter 7.
let it fall.

After the prize balls collide with the prize ball bell 8 when they fall, they are discharged through the outlet 9 into a ball supply tray (not shown) on the front of the pachinko machine.

The prize ball discharge drive device 5 is installed between the collection gutter 10 that guides the winning balls and the collection gutter 11 that collects the winning balls, and tilts the ball case 3 every time one winning ball enters. to eject the prize ball.

The prize ball discharge drive device 5 shown in the embodiment includes a rotary disk 13 having a concave chamber 12 arranged on its circumference for taking in one prize ball as a prize processing means, and a rocker that slides into contact with the upper circumferential surface of the rotary disk 13. Freely movable actuation lever 14
The main components include a motor M that rotationally drives the rotary disk 13, and the like.

Winning balls that have won in the large winning device 15A or the winning device 15B are collected in a collection gutter 17 attached to the back of the game board 16 that collects winning balls, and
A guide gutter 10 extending downward from 7 directs the prize balls to the prize ball ejection drive device 5 while rectifying the flow one by one in a line.

A detection plate 19 that swings slightly depending on the weight of winning balls is provided on the bottom of the passage 18 on the downstream end side of the guide gutter 10 facing the prize ball discharge drive device 5. Micro switch that turns on
A detector 20 having SW ₁ is provided. This micro switch SW ₁ is inserted into a power supply circuit (FIG. 6) that drives the motor M, and when a winning ball is detected, drives the motor M and starts the rotary disk 13.

On the other hand, a detector 21 for detecting the stop position of the rotary disk 13 is provided at the bottom of the rotary disk 13 serving as winning ball processing means.

This detector 21 consists of a micro switch SW ₂ , whose actuator is brought into pressure contact with the circumferential surface of the rotary disk 13, and when the actuator enters the concave chamber 12, it is turned off, and the circumferential surface outside the concave chamber 12 is turned off. It is configured so that it is turned on when it comes into contact with .

This microswitch _SW2 is inserted in parallel with the microswitch _SW1 in the power supply circuit of the motor M (FIG. 6). As a result, when either micro switch SW ₁ or SW ₂ is turned on, the motor M
is driven, and the rotary disk 13 is rotated.

Therefore, now, when the winning ball falls onto the detection plate 19, the micro switch SW ₁ is turned on, the motor M is started, and the rotary disk 13 starts rotating. At the same time, due to the rotation of the rotary disk 13, the other micro switch SW ₂ is activated until the concave chamber 12 is rotated next.
Since it is ON, the winning ball on the detection plate 19 is in the concave chamber 12.
Even if the micro switch SW ₁ is turned OFF due to the rotation of the micro switch SW 1, the rotary disk 13 continues to rotate, and stops when the other micro switch SW ₂ is turned OFF.

That is, the rotary disk 13 stops in a state in which the concave chambers 12 are sequentially fed.

During this time, the winning ball half-fitted into the recessed chamber 12 is transferred while the spherical surface protruding from its circumferential surface is in contact with the lower surface of the operating lever 14, so that the operating lever 14 is gently rocked up and down.

This vertical swinging of the operating lever 14 causes the ball case 3 to be ejected and tilted via the link mechanism 6.

Thereafter, the winning balls naturally drop out of the concave chamber 12 and fall into the collection gutter 11, and the rotary disk 13 stops.

As described above, it is necessary to form at least three concave chambers 12 of the rotary disk 13 according to this embodiment, and when one concave chamber 12 is in the state of receiving a winning ball with respect to the guide gutter 10, the other concave chambers 12 are in a state of receiving winning balls. One concave chamber 12 is in a state where the winning ball has completely fallen into the collection gutter 11, and the other concave chamber 12 is in a state where the winning ball has completely fallen into the collection gutter 11.
Accept SW ₂ actuator and switch
It is configured so that SW ₂ is turned off.

The rotary disk 13 shown in the embodiment has a diameter of 40φ and three concave chambers 12 arranged evenly on the circumferential surface.
Further, the concave chamber 12 is formed so that the winning ball is partially fitted therein, and a part of the spherical surface of the winning ball protrudes from the circumferential surface.

An arc-shaped recessed chamber 22 approximately corresponding to the circumferential surface of the rotary disk 13 is formed on the lower surface of the operating lever 14, so that when a winning ball half-fitted into the recessed chamber 12 comes into contact with the lower surface of the operating lever 14, the winning ball falls off. At the same time, the operating lever 14 is allowed to swing up and down gently.

The guide gutter 10 side of this arcuate recessed chamber 22 is connected to the rotary disk 1
3 is made larger than the circumferential surface so as to create a slight gap with the circumferential surface of the actuating lever 14, thereby smoothing the sliding contact with the winning ball, and reducing the contact area between the lower surface of the operating lever 14 and the circumferential surface as much as possible to reduce friction. Efforts are being made to reduce resistance.

A hook rod 23 is swingably hung in the vicinity of the actuating lever 14 and the rotary disk 13 and swings via a sliding pin 25 that slides on a cam disk 24 arranged in parallel with the rotary disk 13 so as to rotate at the same time as the rotary disk 13. In addition, the engaging pin 26 embedded in the operating lever 4 is configured to freely engage and disengage with the hook portion 27 of the hook rod 23 by swinging, and is engaged at the end of rotation. Then,
The operating lever 14 is operated only when the winning ball is transferred by the rotary disk 13.

The prize ball ejecting mechanism in this embodiment includes the prize ball ejecting drive device 5 which performs the prize ball ejecting operation completely independently of other mechanisms as the winning balls flow down onto the detection plate 19 as described above. It has the following.

In this regard, in the conventional system where a ball shortage detector is provided in the lead-out gutter 4 and used as a start switch for the motor M, the power supply circuit of the motor M is turned off while the ball case 3 is tilting.
There was a drawback that the Tamazaya case 3 stopped in a halfway state when the power was turned OFF, but this drawback has been resolved.

Next, a prize ball detection device 28 that detects the presence or absence of prize balls stored in the prize ball tank 2, and a batted ball supply tray (not shown) and a batted ball firing position (not shown) when a shortage of prize balls is detected. ) will be described.

The prize ball detection device 28 of this embodiment includes a balance weight 30 at one end and a step lever 32 at the center that swings about a rotation shaft 31 as a fulcrum.

The treadle lever 32 is normally set in the outlet gutter 4 directly below the outlet of the prize ball tank 2. Therefore, if there are prize balls, the treadle lever 32 is pushed down by its weight, but if there are not enough prized balls, the balance weight 30 becomes relatively heavy and the treadle lever 32 is flipped up.

This springing motion causes the link mechanism 33 to operate the batted ball supply device 29, and the inlet 34 of the batted ball to the firing position is blocked by the blocking plate 35.

Next, the winning ball control device 36 will be explained.
When the prize ball tank 2 becomes empty, the winning ball control device 36 moves the ball from the treadle lever 32 to the ball case 3.
Utilizing the existence of a large number of stored prize balls remaining in the lead-out gutter 4 leading to this point, the prize ball ejection process is continued for a number of winning balls approximately corresponding to the number of stored prize balls.

This winning ball control device 36 includes a blocking member 37 that prevents the winning balls from flowing down in the middle of the guide gutter 10 that rectifies the winning balls that have flowed into the collection gutter 17 in a line and guides them to the winning ball discharge drive device 5. is provided.

This blocking member 37 operates in conjunction with the operation of a prize ball detection device 28 that detects the presence or absence of prize balls in the prize ball tank 2, and when there are prize balls in the prize ball tank 2, the guide gutter 10
Passageway 18 is opened, and when there is no prize ball, guide channel 1 is opened.
0 passage 18 is opened and closed.

The blocking member 37 that freely opens and closes the passage 18 of the guide gutter 10 is arranged at intervals l corresponding to the number of winning balls that approximately corresponds to the number of winning balls stored in the ball sheath case 3 and the lead-out gutter 4, for example. It is preferable to set it at a position provided between the prize ball ejection drive device 5 and the rotary disk 13.

Therefore, the more prize balls can be stored in the outlet gutter 4, the more prize balls can be discharged even after the prize ball tank 2 is empty.

The blocking member 37 of the embodiment is set such that an interval 1 corresponding to five winning balls is provided between the blocking member 37 and the rotary disk 13 of the winning ball discharge drive device 5.

The blocking member 37 and the winning ball detection device 28 may be interlocked by any mechanical or electrical means.

Referring to FIG. 4, to explain an example of the mechanical interlocking means, a bell crank 38 is provided at the upper part of the guide trough 10 through which the blocking member 37 appears and disappears.
A blocking member 3 is inserted into one arm of the guide 8 from a hole 39 made in the upper surface of the passage 18 of the guide gutter 10 so as to be able to come out and go out.
7 will be provided.

The other arm of the bell crank 38 is connected via an interlocking rod 49 to a link mechanism 33 that links the prize ball detection device 28 and the batted ball supply stop device 29, thereby interlocking the prize ball detection device 28 and the blocking member 37. ing.

In this prize ball discharge mechanism, a prize ball outflow device 40 is provided in the guide channel 10 in correspondence with the prize ball control device 36.

As shown in FIGS. 2, 3, and 4, the winning ball outflow device 40 includes an opening 41 formed in a part of the peripheral wall of the guide gutter 10, and an opening/closing door 42 that opens and closes outward of the passage 18. is provided, and the winning balls flowing down in the passage 18 toward the winning ball discharge drive device 5 are collected outside the machine through the opening 41, through the downflow gutter 43, and the collection gutter 11.

The opening 41 is connected to the blocking member 3 of the prize ball outflow device 40.
7, the winning balls that are prevented from flowing down by the blocking member 37 flow down into the downflow gutter 43 one after another.

In the winning ball outflow device 40 shown in the embodiment, the blocking member 37 extends from the upper side (top side) of the guide gutter 10 to the passage 18.
Since the blocking member 3 is provided so as to be freely retractable inside the
An opening 41 is provided at the bottom of the passage 18 corresponding to the passage 7.

A downstream gutter 43 whose lower end is connected to the collection gutter 11 is connected to the opening 41, and an opening/closing door 42 is provided so as to be opened and closed toward the downstream gutter 43.

The rotation shaft 44 of the opening/closing door 42 is connected to the inclined passage 18.
It is provided on the higher side (right side in FIG. 4), that is, on the upstream side of the guide trough 10.

Further, at the extended end of the rotation shaft 44 on the back side of the back mechanism panel 1, there is an operation dial 4 for opening and closing the opening/closing door 42.
5 is provided at the other end of the rotation shaft 44.
An arm 46 is provided in a direction perpendicular to the four directions, and a spring 47 that normally biases the opening/closing door 42 in a closed state with respect to the opening 41 is secured to this arm.

Therefore, the opening/closing door 42 constitutes the bottom surface of the passage 18 in the normal closed state.

Further, the tip of the opening/closing door 42 is configured to come into contact with the receiving portion 48 of the downflow gutter 43 by rotating the operation dial 45. In this case, it is preferable that the tip of the opening/closing door 42 can be locked onto the receiving portion 48 side.

Note that even if the blocking member 37 closes the guide gutter 10, the winning balls in the guide gutter 10 downstream from the blocking member 37 continue to flow down without being blocked, so as described above, the winning balls are The ejection drive device 5 tilts the ball case 3 to eject a predetermined number of prize balls stored in the lead-out gutter 4 and then collect them in the collection gutter 11.

The winning ball processing means in the embodiment has been explained as the rotary disk 13 of the winning ball ejection drive device 5, but in addition to this, a gutter used in other prize ball ejecting mechanisms may be provided so as to be freely tiltable. It may also be of a structure in which one winning ball is delivered to the player.

(Effect of the invention) Since the present invention is configured as described above, when the prize ball tank becomes empty, the blocking member closes the passage of the guide gutter, and the blocking member closes the passage of the guide gutter.
In other words, winning balls remaining in the guide gutter on the upstream side of the opening can be quickly pulled out of the machine directly from the opening without passing through the winning ball ejection mechanism by opening the opening/closing door.

Therefore, when inspecting the function of the prize ball ejecting mechanism at the final stage of the manufacturing process, or during inspection work when pachinko machines are newly installed in game parlors, the inside of the collection gutter is A large amount of winning balls stored in the ball can be quickly and easily taken out, and work efficiency can be significantly improved.

In addition, when a so-called "termination" is canceled, in which a predetermined number of prize balls are won during operation and the pachinko machine stops playing, the work of inspecting the winning balls stored inside the pachinko machine can be easily and quickly performed. Because you can
The time required for the next player to wait in front of the pachinko machine is shortened, and the game can be resumed more quickly.

Furthermore, the passage of the guide gutter is closed when the prize ball tank becomes empty, so that the winning balls stored downstream of the blocking member are reliably subjected to the prize ball discharge operation,
Since the winning balls stored upstream of the blocking member can be taken out of the machine all at once through the opening by opening the opening/closing door, the structure is simple and has high practical value.
