Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ball ejecting device used in a prize ball ejecting device of a pachinko game machine installed in a pachinko game parlor, a single ball replenishing device of an automatic ball lending machine, etc. This paper relates to effective techniques that can be used in control methods.

[Conventional technology and its problems] As is well known, the prize ball ejecting device of a pachinko game machine installed in a game parlor or the ball ejecting device of an automatic ball rental machine cannot reliably release a preset number of pachinko balls. Required to be discharged.

Therefore, a pachinko ball ejecting device that requires reliable ball ejection has a counting function that counts the pachinko balls ejected into a tray or a storage tank, and a function that counts the number of pachinko balls that are ejected when a predetermined number of pachinko balls are ejected. It is necessary to have a stopper function to stop the discharge.

Conventionally used ejection devices with a ball counting function are designed to measure the dead weight of pachinko balls as they flow down the path from the replenishment chute, which is part of the island equipment, to the pachinko ball ejection port. There is a device in which a ratchet wheel that rotates one pitch at a time is provided, and the rotation is stopped when the ratchet wheel rotates by a predetermined angle. In addition, although it does not have a ball counting function, a swingable ball sheath that can store a predetermined number of pachinko balls is placed on the top of the device, and each time a coin is inserted or a pachinko ball wins, the ball sheath is There is also one in which a predetermined number of pachinko balls stored in a ball sheath are ejected by swinging the ball.

However, although the conventional ball ejection device with the above-mentioned counting function has sufficiently high accuracy when looking only at the counting function, it requires a large storage space due to the large number of mechanical parts. Assembly is complicated,
There are disadvantages and drawbacks such as troublesome maintenance and inspection. On the other hand 1
Conventional ball ejecting devices using ball sheaths are mechanically limited in the number of operations minus the number of balls ejected per operation, and therefore have the problem that the adjustment to change the number of ejected balls is complicated.

Therefore, a ball ejecting device has been proposed which combines an electrical counting means and an electromagnetically actuated stopper.

This type of stopper fireball ejector can achieve extremely high accuracy due to recent advances in sensor technology and electronics if we focus on the counting function, but the stopper function is not necessarily limited to the counting function. However, sufficient responsiveness could not be guaranteed.

Therefore, the inventor of the present invention has studied the factors that prevent sufficient response from being obtained regarding the stopper function in the stopper fireball ejecting device, and has come to the following conclusion.

(1) In the stopper fireball ejecting device, it is impossible to match the position of the sensor and the position of the blocking member (stopper) due to mechanical constraints, and after a certain pachinko ball passes the sensor position, the blocking member It takes some time to reach the stopping position.

(2) In order to always discharge only a predetermined number of pachinko balls while operating the blocking member at certain timings as described above, the falling speed of the pachinko balls passing between the sensor and the blocking member must be at least is constant, and there must be a certain distance between the pachinko ball and the next pachinko ball just before the blocking member is activated.

(3) However, in reality, the flow velocity and ball spacing of pachinko balls flowing down the flow path vary widely due to various factors. Even if the relative actuation timing of the blocking member is slightly earlier or slightly later than the flow velocity of the pachinko balls, it cannot be guaranteed that a predetermined number of pachinko balls can be accurately ejected. In other words, even if the activation time of the blocking member is constant, the activation timing differs each time due to variations in the speed of the falling balls and the distance between the balls, and reliability cannot be guaranteed.

(4) When a spring is used as a means for returning the blocking member to the flow blocking position, the operating time of the blocking member varies due to variations in the spring constant.

The activation timing differs depending on the product.

For the above reasons, in the stopper fireball ejecting device, high precision is required for each component, and high precision is also required in the assembly work. Therefore, when mass production is started, strict quality checks must be carried out. Furthermore, if the above checks result in a defective product due to variations in parts or errors that sometimes occur in assembly, the product loses its value as a product.

[Object of the Invention] The object of the invention is to provide a stopper type ball ejection device,
It is an object of the present invention to provide a discharge control technique that can accurately discharge a predetermined number of pachinko balls by reducing the influence of variations in component parts.

[Structure of the Invention] The present invention provides a stopper-type ball discharging device that includes an alignment gutter that has a gentle slope and aligns the falling pachinko balls, and a flow path along which the ejected pachinko balls flow downward. A nearly vertical flow regulation value that accelerates the aligned pachinko balls by their own weight and causes them to flow down; and a substantially vertical flow regulation value that is provided at the boundary between the alignment gutter and the flow regulation value that temporarily decelerates the speed of the aligned pachinko balls that flow downward. and an adjustment section that changes the direction of the flow, and a guide gutter that extends obliquely downward from the end of the flow regulation value and allows the blocking member to enter and retreat. In addition to giving the balls a stable speed and a predetermined ball spacing, a falling prevention member (
The displacement time required for the displacement of the stopper) is investigated in advance, and the drive source of the blocking member is controlled so that the time difference between the falling ball and the falling time required for the falling ball to flow down from the detection position to the falling blocking position is electrically interpolated. By controlling the ball, the relative operating timing of the blocking member and the falling ball is kept constant, the influence of variations in component parts is reduced, and a predetermined number of pachinko balls can be accurately ejected. It is.

[Embodiment] FIGS. 1 and 2 show an embodiment of the main part of a ball ejecting device according to the present invention.

In this embodiment, a machine component 1 constituting the main part of the pachinko ball ejection path and a ball ejection device 2 for preventing or releasing the pachinko balls flowing down the pachinko ball ejection path are held. A holding body 3 is integrally formed. A solenoid 21 serving as a driving means for the ball ejecting device 2 is fixed to the holder 3 .

The machine component 1 includes a gently inclined alignment gutter 11, a flow adjustment value 13 extending substantially vertically downward from the downstream end of the alignment gutter 11, and a connection between the alignment gutter 11 and the flow adjustment value 13. Adjustment part 1 that changes the direction of the falling ball by about 90 degrees.
2, an induction gutter 14 extending diagonally downward at an angle of about 45 degrees from the lower end of the flow adjustment value 13, and a discharge gutter 15 extending approximately vertically downward from the terminal end of the induction gutter 14. ing.

A pair of support pieces 16 protrude from the outer wall of the machine component 1 near the boundary between the guide gutter 14 and the discharge gutter 15, and the support shaft 4 is horizontally suspended between the support pieces 16.

Although not particularly limited, in this embodiment, two ejection paths for pachinko balls are formed, and corresponding to these two ejection paths, a pair of fan-shaped flow prevention blocks are provided on the support shaft 4. A member 22 is rotatably mounted. A pair of solenoids 21 are also provided corresponding to the flow prevention members 22.

The tip end of the flow prevention member 22 enters through a slit provided in the inner wall of the machine component 1 and projects into the guide gutter 14. The above-mentioned flow prevention member 22
The rear end of the solenoid 21 is connected to the end of the plunger 21a of the solenoid 21 through a link member 23, and as the plunger 21a expands and contracts, the flow prevention member 22 is reciprocated around the support shaft 4. The tip portion enters into the guide trough 14 and retreats.

Further, the side wall of the guide gutter 14 is bulged to the outside, and the storage section 1
7 is formed, and a falling ball detector 5 consisting of a transmission type optical sensor is inserted into this storage portion 17. The details of the storage section 17 are shown in FIG. Also, the 6th
The figure shows a slit 19 formed continuously in this storage portion 17 through which the flow prevention member 22 enters.

In addition, on the upper part of the holder 3, the lead wires drawn out from the solenoid 21 and the falling ball detector 5 are concentrated in one place, and the wiring for connecting to the control device of the pachinko game machine etc. is connected from the front. A connector 6 is provided to allow simultaneous connection.

Furthermore, in this embodiment, as shown by the chain line A in FIG. , is connected to the terminal end of the supply gutter 1o that guides the balls in the pachinko ball storage tank 7. Near the end of the supply gutter 1O, there is a pressure reducing part 1 with a step.
8 is formed.

FIG. 3 shows an embodiment in which the supply gutter 10 having the pressure reducing section 18 is integrated with the machine component 1 and the ball discharge device 2.

In this embodiment, each gutter member constituting the two flow paths in the above embodiment, the flow prevention member 22 corresponding to each flow path, and the solenoid 21 serving as its driving means are each held between a pair of parallel plates 24. ing. These two sets of parallel plates 24 are integrally connected to each other by a connecting rod 25. Further, the supply gutter 10 is placed on a connecting rod 25 provided at the rear end of the parallel plate 24.

As a result, the machine component 1, the ball ejecting device 2, and the supply gutter 10 are integrally held between the two sets of parallel plates 24, and can be installed as a one-touch ball ejecting device in a pachinko game machine or a surrounding ball rental machine. In addition to being able to be incorporated into the system, the entire device can be configured compactly.

In the embodiment shown in FIG. 3, a stopper pin 26 is provided protruding from the side of the flow prevention member 22, and is supplied to an arcuate guide hole 24a formed in the parallel plate 24, so that the flow prevention member 22 The range of rotation is regulated. Also,
The pin 27 suspended horizontally at the lower front end of the parallel plate 24 has a
A spring 28 is stretched between the distal end of the flow prevention member 22 to assist the rotation of the flow prevention member 22 by the return spring 21b in the solenoid 21, and to quickly rotate the flow prevention member 22 at the end of discharge. This makes it possible to prevent the ejection of falling balls. However, when the spring 28 is provided, it is also possible not to provide the return spring 21b inside the solenoid 21.

In the case of the above embodiment, the supply gutter 10 and the alignment gutter 11 can be considered as one alignment gutter. In that case, the pressure reducing section 18
will be installed in the middle of the alignment gutter.

Next, the operation of the flow path (1) and the ball discharge device configured as described above will be explained in detail using FIG. 4.

When the fan-shaped flow prevention member 22 enters the guiding path 14 as shown by the solid line in FIG. It is stopped by contacting the outer peripheral surface of the blocking member 22.

At this time, there are two balls B2 in the guide gutter 14.

In addition, the induction fl! ! 14 and the dimensions of the flow regulating section 13 are determined respectively. Moreover, the uppermost ball B5 in the flow adjustment section 13 is pushed by the balls B, B7, etc. in the alignment gutter 11 and comes into contact with the tapered adjustment section 12. . By being pressed toward the adjustment section 12, the ball B receives a repulsive force from the adjustment section 12, and the repulsion force is applied to the ball B5 and the balls below it B4. It is transmitted to B3... and acts to push them downward. As a result, when the flow prevention member 22 is retreated from the guide gutter 14 as shown by the broken line C in FIG.
The inner balls B1 to B5 quickly begin to flow down.

When the balls B□~B flow down, the balls BGIB7 in the alignment gutter 11
... starts flowing down following this. Then, at the exit of the alignment gutter 11, the flow first collides with the adjustment part 12 to reduce the flow rate, and the flow direction changes from the horizontal direction to the vertical direction by about 90 degrees.
°converted and enters the flow regulating section 13.

Since acceleration is performed there due to its own weight, the adjustment section 12
A distance between the balls and the following balls that are decelerated by the ball is ensured. Therefore, the output waveform of the detector 5 becomes as shown in FIG.
Detection interval t2 of subsequent balls B6, B7...
becomes wider. As a result, for example, if the solenoid 21 is demagnetized when the ball B7 is detected, it is possible to prevent the ball B from flowing down before it passes even if there is a delay in the operation of the flow prevention member 22.

On the other hand, since the alignment gutter 11 is provided with the pressure reducing section 18, the balls B□□ and B1□ on the upstream side of the pressure reducing section 18.

Since the ball pressure due to the weight of the upstream ball transmitted through ... acts in the horizontal direction, a considerable portion is absorbed by the pressure reducing section 18. This will stop (wait)
In this state, the ball pressure transmitted to the ball B□ is hardly transmitted to the flow regulating value 13 or the balls B to B in the induction gutter 14, so the pressure acting on the flow prevention member 22 is also reduced. As a result, the flow prevention member 22 can be moved backward with a relatively small force. The tilt angle of alignment @11 is 7°
Preferably before and after.

Further, in the flow down path, the center 0 of the ball B located at the uppermost part of the flow adjustment value 12 is aligned in the alignment gutter 11 with the ball 86 being prevented from flowing down by the flow prevention member 22.
~B□. The induction gutter 14 and the flow adjustment value 13 are positioned below the extension line of the center line connecting the centers 06 to 01°.
dimensions have been determined.

Therefore, the pressure transmitted from the waiting ball 86 to B1° to B generates a force that pushes down the ball B5.

As a result, when the flow prevention member 22 retreats, the uppermost ball B5 of flow regulation value 13 is sandwiched between the following ball BG and the outer wall 13a of flow regulation value 13, and the balls B, to B4 are They are not prevented from trying to follow the flow of water.

The falling ball detector 5 installed in the middle of the guide gutter 14 is
The detection optical axis F is located at a position slightly away from the center of the sphere flowing down the gutter. If the detection optical axis F is positioned so that it passes through the center of the sphere, if multiple spheres come down in succession, the pulse interval of the detection signal will become narrow and accurate counting may not be possible. . However, in this embodiment, as described above, by shifting the detection optical axis F from the center of the sphere, accurate counting becomes possible.

Further, in the above embodiment, the fan-shaped flow prevention member 22a
The flow prevention member 22 is attached so that the rotating surface of the ball coincides with the trajectory of the center of the falling ball, and is moved from above the guide gutter 14 to enter the gutter downward to prevent the falling ball from falling. It is designed to stop. Therefore, when the falling ball stops, the impact force acting on the falling ball stopping member 22 is absorbed by the stopper part (for example, the end of the guide hole 24a in FIG. Since the receiver can be stopped at the slit end of the guide trough 14 into which the guide trough 14 enters, it can easily be made strong enough to withstand the shock that occurs when the guide trough 14 enters.

Moreover, since the ball B at the lowest end comes into contact with the outer peripheral surface of the fan-shaped flow prevention member 22 and is stopped, the lowermost ball B □ is between the outer peripheral surface of the flow prevention member 22 and the wall surface of the guide gutter 14 Even if it is stopped in such a way that it bites into the ball, when the flow prevention member 22 is retreated, it moves away while rotating the ball B□ on its outer peripheral surface. Therefore, the flow prevention member 22 can be retreated with a relatively small force, and the flow prevention member 22 can be moved backward.
There is no possibility that the ball will be caught between the wall surface of the guide gutter 14 and the ribs will be lost.

Furthermore, it is arranged so that the line connecting the rotation center of the flow prevention member 22 and the center 01 of the lowest ball B□ in the guide gutter 14 is horizontal. Therefore, as soon as the end of the flow prevention member 22 comes off the outer periphery of the ball B□, the ball B becomes able to flow down, and after the ball B□ slides down a little as the flow prevention member 22 rotates, the blocking force is released. and will not start flowing down.

Further, in the above embodiment, the angle α between the flow regulation value 13 and the induction gutter 14 may be in the range of 0 to 90';
If it is set before or after ``, the speed of the falling ball that has been accelerated within the flow adjustment value 13 will not be significantly reduced, and the load on the falling ball 22 when stopped can be reduced.

Further, in the above embodiment, when the ball is prevented from flowing down by the flow prevention member 22, the contact point between the flow prevention member 22 and the lowest ball B1 in the guide gutter 14 is separated by the diameter of the ball. The vertical line G passing through the point and the wall surface 15 of the discharge gutter 15
The distance d from a is smaller than the radius r of the sphere, and r - r
cQ becomes larger than Sα (r-rcosα< d
<r) The position of the terminal end 14a of the guide gutter 14 is determined as follows.

As a result, when the flow prevention member 22 enters the guide gutter 14 and prevents the balls from flowing down, the last ball to be discharged is pushed back by the end surface 22a of the flow prevention member 22, and when the ball is discharged. When it reaches the terminal end L4a of the guide gutter 14, it flows down into the discharge gutter 15 and can escape from the flow prevention member 22. Therefore, the final discharge bulb remains in the guide pipe 1.
5 and does not obstruct the entry of the flow prevention member 22, making it possible to quickly stop the discharge.

However, the guide gutter 14 can also be extended as shown by the chain line E.

Incidentally, when a spring 23 is used as a means for applying a force to cause the flow prevention member 22 to enter the guide gutter 14 as in the embodiment shown in FIG.

The spring 23 is, as shown by the broken line C in FIG.
It is preferable to dispose the spring 28 so that the line of action of the spring 28 is approximately perpendicular to the end surface 22a of the flow prevention member 22 when the end of the flow prevention member 22 begins to enter the guide gutter 14.

As a result, when the falling ball 22 comes into contact with the ball in the guide gutter 14, the rotational speed is set to be the highest, and the falling ball can be stopped crisply.

By configuring the downstream path of the ball discharge device as in the above embodiment, it is possible to impart a stable velocity and ball spacing to the descending balls. As a result, it is possible to experimentally and accurately know the flow time T from the detection position of the falling ball by the detector 5 to the time when the falling ball reaches the flow prevention position by the flow prevention member 22. Therefore, if the solenoid 21 is actuated to cause the flow prevention member 22 to enter the flow path in accordance with this flow time T, when the last ball detected by the detector 5 has just arrived at the flow prevention position. You can stop the flow of the ball.

However, in this case, consideration must also be given to the displacement time required for the falling ball blocking member 22 to move to the position where it actually blocks the falling ball after the demagnetization signal is applied to the solenoid 21. In the above embodiment, since the velocity of the falling ball is stable, the falling time T is also constant, so the detector 5 is installed so that the falling time T and the displacement time X of the falling preventing member 22 match. All you have to do is decide on the location.

However, although the velocity of the falling sphere is stable in the falling path of the above embodiment, if the image forming member 1 is formed of plastic or the like, the falling velocity may vary depending on the product. In addition, the restoring force of the springs for returning the flow prevention member 22 is not uniform due to variations in the manufacturing process or changes over time, so the rotational speed of the flow prevention member 22 varies depending on the product, and the flow prevention timing is There is also a risk of slight deviation.

Therefore, in the present invention, the difference between the falling time T from the detection position of the falling ball to the blocking position and the displacement time X of the falling ball blocking member 22 is interpolated by setting a delay time through electrical control. .

Next, an embodiment of a control device that controls the ball ejecting device configured as described above to eject a predetermined number of balls and interpolates displacement time will be described with reference to FIG.

In this embodiment, the ball ejection device is controlled using a CPU (microcomputer).

A discharge request signal So is input to the CPU 200. When the above ball ejecting device is used as a prize ball ejecting device of a pachinko game machine, the signal from the winning ball detector is transmitted, and when the ball ejecting device is used as a ball lending machine, the signal from the coin detector is transmitted. In addition, when used as a replenishment device for a spare ball storage tank of a pachinko game machine or a ball rental machine, the replenishment request signal is sent to the CPU 200 as the discharge request signal SO, respectively.
is input.

In addition, the CPU 200 receives the ejected ball detection signals Sl and S2 from the pair of detectors 5 provided in the middle of the downstream path 1 of the ball ejecting device 2, which are waveform-shaped by waveform shaping circuits 211 and 212, and then filtered. 213 and 214, only regular detection signals are extracted and input. Furthermore, delay time data is input to the CPU 200 from a delay time setting means 210 that can be adjusted using a volume or an up/down type digital setting device.

The CPU 200 has an internal read-only memory ROM2.
01 and RAM which is a memory that can be read and written at any time.
202 is provided. Among these, the ROM 201 contains a program to be executed by the CPU 200 to control the ball ejecting device, etc., and a program for ejecting the balls through two flow paths in the ball ejecting device 2 in response to a single ejection request signal SO. Fixed data such as numbers (base 1, 2) and wait times (ejection intervals) are stored.

On the other hand, the RAM 202 stores the ejected ball detection signal SL.

Based on S2, a register area for storing the cumulative number of balls ejected from each downstream path and forming a soft timer and a work area for the CPU 200 are provided.

Furthermore, the CPU 200 has a driver 221゜2.
22 and 223 are connected, and when the discharge request signal S○ is input, the driver 221 is driven to light the discharge display lamp LMP, and the drivers 222 and 223 are connected.
and energizes the solenoid SQL (21), which is a pair of discharge drive means in the ball discharge device.

As a result, the flow prevention member 22 is retreated from the flow path 1, and a predetermined number of balls are discharged.

230 is a power supply section of the CPU 200.

Next, the control device operates the ball ejection device,
An example of a control procedure for accurately discharging a desired number of balls will be described with reference to the flowchart of FIG.

Note that FIG. 8 shows the configuration of the register area within the CPU 200 when the ejection process is performed according to the flow shown in FIG. 9.

When the CPU is started, it first starts accessing the ROM 201 and sequentially reads and executes the instructions of the program stored there. As a result, a series of discharge processing shown in FIG. 9 is started. When the discharge process starts, first,
The discharge request signal SO is read (routine R1), and it is determined whether there is a rising edge of the signal, that is, the discharge request signal SO.
has changed to a high level (routine R2).
).

When there is etch, 1 is added to the value of the instruction register (see FIG. 8) in the RAM 202 (routine R3
), the program proceeds to routine R4. If there is no signal etch, jump from routine 2 to R4. In routine R4, the mode register in the RAM 202 is checked to determine whether or not the modes related to the two ejection routes of ejection system 1 and ejection system 2, that is, the ball ejection device, are set to "0". Here, if the mode is "0", the process moves to the discharge system 1. However, when the system starts operating, the registers are once rO
J, the judgment result in the first routine R4 is
The answer is yes (Y) and the process proceeds to routine R5.

In the routine R5, it is determined whether the value of the instruction register in the RAM 202 is "0" or not. If it is "O", the process moves to the exhaust system 1, and if it is not rOJ, that is, if ≠O, then the routine R6 Move to.

Therefore, when 1 is added to the instruction register in the routine R3, the process always moves to the routine R6.

In routine R6, discharge system 1 and discharge system 2 in the bulb discharge device
Excite the two solenoids and start discharging. Then, after lighting the lamps LM and P indicating that the discharge is in progress (routine R7), the mode set in the mode registers of the discharge systems 1 and 2 in the RAM 202 is changed to r.
OJ is changed to "1" and the process moves to the next process of the exhaust system 1 (routines RIL to R27).

In the process of the exhaust system 1, first the mode register 1 of the exhaust system 1 is
, and determines whether the mode is "1" (routine R11). If the mode is "1", the program proceeds to the next routine, reads the signal from the ejected bulb detector, and determines whether or not there is an etch in the signal (R12, R13). Here, if the signal is not etched, the process of the discharge system 1 is ended and the process proceeds to the process of the discharge system 2. If a signal is etched, 1 is added to the value of the discharge register 1 in the RAM.

In other words, the number of ejected balls is increased by one (routine R14).

Then, the value of ejection register 1 is set to a predetermined base 1
It is determined whether the number of balls has reached the set number of balls for the discharge system 1 (routine R15), and if it has not reached the set number of balls, the process moves to the process for the discharge system 2 (routines R31 to R47).

In the process of the discharge system 2, regarding the discharge system 2 of the bulb discharge device,
The mode determination (R31) and the check of the ejected bulb detection signal (R
32, R33), the ejection register is added (R34), and the number of ejected balls is checked (R35), and if the predetermined number has not been reached, the process moves to post-processing (routines R51 to R56).

In post-processing, first look at the mode registers of exhaust systems 1 and 2 to determine whether the mode is set to "3" for both. If the mode is not "3", jump to R53, and then set the mode to "3" for both. 4". and,
If the mode is not “4”, repeat the routine R1~
Return to the discharge process consisting of R8.

While the above procedure is repeatedly executed, when the number of balls ejected by the ejection system 1 of the ball ejecting device reaches a predetermined number (base 1), a yes is determined in routine R15 of the ejection system 1 processing, and the routine Proceed to R16, set delay timer 1 of discharge system 1 in RAM, and then set mode 1 in mode register 1.
is changed to mode 2 (routine R17). Similarly, when the number of balls ejected by ejection system 2 reaches a predetermined number (base 2),
In the routine R35 for exhaust system 2 processing, the determination is YES and the process proceeds to routine R36, where the delay timer 2 of the exhaust system 2 in the RAM is set, and then the mode 1 in the mode register 2 is changed to mode 2 (routine R37). ).

When moving to post-processing, it is determined in routine R51 whether the modes of exhaust systems 1 and 2 are both "3", but since they are still "2" at this time, the routine R53 jumps to "NO" (NO). ), and the process returns to the first discharge process (R1-R8). When executing this discharge process, since the mode is already "2", the routine jumps directly to the discharge system 1 process from routine R4.

Then, when it comes to exhaust system 1 processing, routine R11
Then jumps to routine R18, where it is judged as YES, and proceeds to the next routine R19, where delay timer 1 is set.
Subtract 1 from . Well, delay timer 1 is "0".
”, and if it is not “0”, the process moves to the discharge system 2. In the discharge system 2 treatment as well, the same process as described above is performed for the discharge system 2, and then the post-treatment is started.

In this way, by repeating the above steps, the delay timer 1 is gradually decreased, and when the preset delay time for displacement time interpolation has elapsed, the delay timer becomes "0".
become. Then, the routine proceeds from R20 to R21, where the discharge solenoid 1 is turned off to stop the discharge. after that,
After setting wait timer 1 in preparation for the next discharge (routine R22), while changing the mode of mode register 1 from "2" to "3" (routine R23),
Move to processing.

In the discharge system 2 processing, when it is determined that the delay timer 2 has reached rOJ, the discharge solenoid 2 is turned off, the way 1-timer 2 is set, and the mote register 2 is changed from r2J to "3" (R41 ~R43).

After that, when moving to post-processing, it is determined in routine R51 that the modes of discharge systems 1 and 2 are both "3", so the routine proceeds to routine R52, and after turning off the lamp LMP indicating that discharge is in progress, .

Return to initial processing.

When the next ejection request signal is received during the ejection process in the bulb ejecting device, the number of ejection requests is stored by reading the signal etch in routine R2 and adding the instruction register (routine R3).

Discharge processing after turning off the discharge solenoid (R1-R8)
When the routine returns to , the modes of the exhaust systems 1 and 2 are set to "3", so the routine jumps directly to the exhaust system 1 process from routine R4. Then, the process proceeds from routine R11 to R18, where it is determined to be NO and jumps to the next routine R24. Here, it is determined to be YES, that is, the mode is "3", and the process proceeds to routine R25 to go to way 1 and timer 1.
After subtracting "1" from , it is determined whether wait timer 1 has reached "o" (routine R26). If wait timer 1 is not “0”, move to discharge system 2 processing and R
31, R38→R44→R45, similar processing is performed using wait timer 2, and the process moves to post-processing.

While repeating the above procedure, when a predetermined time has elapsed, it is determined that the wait timer has reached rOJ in routine R26 for exhaust system 1 processing and routine R46 for exhaust system 2 processing, and the next routine R27 is started. Proceeding to R47, the modes of mode registers 1 and 2 are changed from "3" to "4", and the process proceeds to post-processing.

Then, in the post-processing, a YES determination is made in routine R53, and the process proceeds to the next routine R54, where the instruction register is subtracted. In other words, the number of stored discharge request signals is decreased by "1" after a certain period of time has elapsed since the completion of the - times of discharge processing. Then, after clearing the values of ejection registers 1 and 2 that store the number of ejected balls in each ejection route, mode registers 1 and 2 are cleared.
The mode is changed from "3" to "O" again, and the process returns to the beginning (routines R55 and R56).

By repeating the above procedure, the ball ejection device ejects a predetermined number of balls a number of times corresponding to the number of ejection request signals. The CPU is interrupted, for example, once every 2 msec, and executes the ejection process according to the above flow. Therefore,
Timer management becomes possible by counting the number of interrupts.

If you want to change the number of balls ejected at one time by the ball ejecting device, change the number of bases 1 and 2 of the fixed data in the ROM 201.
This can be easily achieved by rewriting .

[Operation/Effect] As explained above, the present invention provides a stopper-type ball discharging device in which a downstream path along which the discharged pachinko balls flow is formed by a sorting gutter that has a gentle slope and aligns the falling pachinko balls. , an almost vertical flow regulation value that accelerates the pachinko balls aligned in this alignment gutter using their own weight and causes them to flow down;
An adjusting section provided at the boundary between the alignment gutter and the flow regulation value, which temporarily decelerates the speed of the pachinko balls that are aligned and flowing down, and changes the direction of the flow; The blocking member is extended toward the
By constructing it with a retractable guide gutter,
In addition to imparting a stable speed and a predetermined ball spacing to the falling balls, the displacement time required for the displacement of the falling ball (stopper) is investigated in advance, and the falling ball is made to flow down from the detection position to the falling blocking position. Since the driving source of the blocking member is controlled so as to electrically interpolate the time difference between the required falling time and the falling ball, the relative actuation timing of the blocking member and the falling ball is kept constant, so that the component parts are This has the effect of reducing the influence of variations and accurately ejecting a predetermined number of pachinko balls.

Moreover, in the present invention, as explained in the above embodiment, the operating timing of the flow prevention member is electrically adjusted. Parts do not need extremely high precision, and detectors and the like do not need to be mounted with very high precision. Therefore, quality control becomes easier, and assembly work can be performed easily and efficiently.

As a result, whereas in the past, small installation errors could result in loss of product value, adjusting the actuation timing described above eliminates this and reduces the incidence of defective products. .
