DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball feeding control device, and more particularly to a pachinko ball feeding control device for sequentially feeding pachinko balls using a motor as a drive source.

[0002]

2. Description of the Related Art Conventionally, in this type of pachinko ball delivery control device, pachinko balls collected in a ball passage and forming a column are temporarily stopped by a stopper, and the stopper is opened and closed by a solenoid or the like based on a signal from a control means. In addition, a feeding device that feeds pachinko balls one by one by the weight of the pachinko balls and a control device that simply turns on and off the pachinko balls have been used. In such a configuration, there is a problem in that the accuracy of ball counting and the speed of sending out the ball are low, and furthermore, if a failure occurs while the stopper or the like is open, the ball may remain out. Therefore, in order to solve this, a motor such as a DC motor is used as a drive source, and a bead cutting disk having a cutout on the outer periphery thereof with a notch into which a pachinko ball can be fitted is provided so that the outer periphery faces the ball passage, and in response to a winning signal. Japanese Patent Application Laid-Open No. 63-164977 discloses a device using a device for rotating a lever-cutting disk at a predetermined angle and feeding out a required number of pachinko balls.

[0003]

However, in the case of using a motor to discharge pachinko balls by rotating the motor, there is a problem in that the motor is used and the entire apparatus becomes large. On the other hand, if the motor is simply reduced in size, the driving force may be insufficient, and the reliability in reliably sending out pachinko balls is lacking. In particular, in the case of pachinko balls, the ease of feeding varies considerably depending on the quality of the oil and the like. The conditions under which the pachinko balls can be reliably discharged also differ depending on the conditions of the balls before and after the delivery mechanism, the environmental temperature, the humidity and the like.

Further, in the case of a pachinko ball feeding mechanism, it is extremely difficult to completely prevent an unexpected situation such as pachinko ball biting, and in such a case, a structure for surely discharging the pachinko ball has been desired. . The pachinko ball delivery control device of the present invention has been made to solve the above-described problems and to reduce the size of the device and improve reliability.

Here, the control of the operating state of the electric motor is performed, for example, by varying its rotational speed, and is based on the state of the pachinko balls detected by the pachinko ball detecting means, so that the pachinko balls can be easily sent out. A pachinko ball discharging mechanism that increases the discharge speed of the pachinko ball discharger in an easier state, and reduces the discharge speed in a more difficult state of discharge. Can be. Similarly, the torque of the pachinko ball discharging mechanism, the voltage applied to the electric motor, the pulse width thereof, and the like may be varied depending on whether it is easy or difficult to feed the pachinko balls.

Next, an electronic control unit 60 for controlling the entire pachinko machine and a configuration around the delivery device 20 controlled by the electronic control unit 60 will be described with reference to FIG. The electronic control unit 60 mainly includes a well-known arithmetic and logic operation unit, a ROM, a RAM, and the like. The electronic control unit 60 receives signals from the various switches described above, and controls the delivery device 20 or a display element group such as a winning display lamp (not shown).

Ball supply interlock switch 15, ball jam interlock switch 17, ball confirmation switch 1
8, various switches such as a prize ball confirmation switch 19, first, second, and third start switches 24, an upper and lower tray interlock switch 27 are connected to input ports of the electronic control unit 60,
The ball firing device 14, the stepping motor 50 of the delivery device 20, and the like are connected to output ports.
In the electronic control unit 60, an interface circuit corresponding to these switches and external devices is provided.
Here, illustration and description are omitted.

The configuration of the ball confirmation switch 18 and the prize ball confirmation switch 19 used in this embodiment will be described. The ball confirmation switch 18 and the prize ball confirmation switch 19 are the same except that the ball confirmation switch 18 has two detection coils L1 and L2 and the prize ball confirmation switch 19 has a single coil L1. It has a configuration of Therefore, taking the ball confirmation switch 18 as an example, these switches and the electronic control unit 6
The configuration of the pachinko ball and the connection with the electronic control unit 60 and the principle of detecting a pachinko ball will be described. As shown in FIG. 5, the ball confirmation switch 18 and the prize ball confirmation switch 19
Includes a housing 71 having a U-shaped cross section, and a substrate 73 provided therein. One end of the substrate 73 protrudes out of the housing 71 and is used as a connection terminal 75. Electronic components such as the transistor shown in FIG. 6 are assembled on the substrate 73. The coils L1 and L2 are stored in the protruding storage sections 81 and 82 of the U-shaped casing 71. The distance between the centers of the storage sections 81 and 82, that is, the coil L
The center distance between L1 and L2 is exactly 1.5 times the diameter of the pachinko ball B.

As shown in FIG. 6, the ball confirmation switch 18 has a power supply terminal T1 supplied with 12 volts and a detection terminal T2 connected to the input port PB1 of the electronic control unit 60.
And This detection terminal T2 also serves as the ground level of the circuit, and is grounded via the resistor RD on the electronic control unit 60 side.

The ball confirmation switch 18 is a high-frequency oscillation circuit C
O and ON based on the oscillation state of the high-frequency oscillation circuit CO
And a switching circuit SW that is turned off.
The high-frequency oscillation circuit CO includes a double transistor Tr1 in which two transistors having the same characteristics are formed in the same chip, and a resistor R3 and a capacitor C interposed between both emitters of the double transistor Tr1 and the ground line.
1 and C2 and the coils L1 and L2 constitute a Colpitts-type high-frequency oscillation circuit. The base of the double transistor Tr1 is connected to a power supply line via a resistor R2. When the pachinko ball B is not approaching the coils L1 and L2, the high-frequency oscillation circuit CO has the inductance of the coils L1 and L2 and the capacitor C
It oscillates at an oscillating frequency determined by the capacitances of C1 and C2. The oscillation frequency in this embodiment is about 300 KHz. When the pachinko ball B approaches any one of the coils L1 and L2, an eddy current is generated inside the pachinko ball B due to the magnetic flux generated by the coils L1 and L2, and the oscillation of the high-frequency oscillation circuit CO is attenuated by the eddy current loss. Stop.

The double transistor Tr of the high frequency oscillation circuit CO
1 switching circuit SW connected to the collector terminal
Is formed around the transistor Tr2, and the transistor Tr2 is turned on or off according to the state where the twin transistor Tr1 is oscillating or the state where the oscillation is stopped. A voltage of 12 volts is applied to the collector terminal of the transistor Tr2 from the power supply terminal T1, but since the detection terminal T2 is grounded by the resistor RD (the resistance value is 680Ω in this embodiment), the transistor Tr2 , The voltage of the detection terminal T2 changes. The electronic control unit 60 can detect the state of the ball confirmation switch 18 from the change in the voltage.

This point will be described in some detail. The resistance of the resistor R4 connected to the emitter terminal of the transistor Tr2 is smaller than that of the resistor R1 at the power supply terminal T1 (220 Ω: 27 KΩ in the present embodiment). ,
The current flowing through the Zener diode D1 via the resistor R4 is larger than the current flowing through the resistor R1 (about 130 times). Since this current finally flows to the ground side via the resistor RD of the electronic control device 60 connected to the detection terminal T2, the voltage across the resistor RD,
That is, the voltage of the input port PB1 of the electronic control unit 60 is about 0.2 volts when the transistor Tr2 is off and about 4.9 volts when the transistor Tr2 is on. Therefore, the electronic control unit 60
By monitoring the state of the input port PB1, it is possible to easily know the state where the ball confirmation switch 18 is detecting the pachinko ball B (low level) and the state where it is not detected (high level).

The coils L1 and L of the ball confirmation switch 18
2, the center-to-center distance DL is 1.5 times the diameter of the pachinko ball B as shown in FIG. Therefore, when the center of the pachinko ball B is located at the center of the coil L1 (maximum magnetic flux density), the center of the coil L2 is located substantially corresponding to the contact point of the adjacent pachinko balls. In other words, as the center of the coil L1 deviates from the center of the pachinko ball, the center of the pachinko ball approaches the center of the coil L2. Therefore, if the pachinko balls are adjacent to each other, even if the entire pachinko balls are moving, eddy current loss occurs due to one of the magnetic fluxes of the coils L1 and L2, and the oscillation of the high-frequency oscillation circuit CO is constantly performed. It is almost stopped, and the transistor Tr of the switching circuit SW
2 is turned off, and the input port PB1 of the electronic control unit 60 becomes low level.

On the other hand, since the coil L2 does not exist in the prize ball confirming switch 19, the oscillation of the high-frequency oscillation circuit CO is interrupted every time the pachinko ball B passes, and the pachinko ball continues to be very close. , The detection terminal T2 goes low for a short time in accordance with the passage of each pachinko ball B. Therefore, by monitoring the level of the input port PB2, the electronic control unit 60 can individually detect the passage of the prize ball and count it.

The processing executed by the electronic control unit 60 having the above configuration will be described. When the start switch 24 detects a winning ball, the electronic control device 60 of the present embodiment executes a premium ball payout processing routine shown in FIG. When this routine is started, first, a process of setting a predetermined number S to a variable i for counting the number of payouts is performed (step S100). In a normal pachinko machine, a value 7 or 15 is set to the variable i. Then, the delivery device 2
A process for controlling the zero stepping motor 50 to its minimum drive speed is performed (step S110). Since a large driving force is required at the time of starting the stepping motor 50, a large driving power is applied as shown in FIG.

Subsequently, it is determined whether or not the payout of the pachinko ball has been detected within the predetermined time t1 (step S).
120). When the stepping motor 50 is driven at the minimum driving speed and the ball cutting plate 41 rotates and the pachinko ball is normally sent out, the prize ball confirmation switch 19 detects this, and the payout of the pachinko ball is confirmed based on this signal. Is done. If the payout is detected within the predetermined time t1, the variable i indicating the remaining number of free prize balls is decremented by 1 (step S130), and it is determined that the payout of the pachinko balls is normally performed. , The value Fr is set to 0 (step S140).

Thereafter, it is determined whether or not the variable i is a value 0 (step S150). If it is determined that the variable i is not a value 0, that is, it is determined that there are prize balls that have not been paid out yet, the stepping motor It is determined whether or not the driving speed is the maximum speed (step S160). If it is determined that the driving speed is not the maximum speed yet, a process of increasing the driving speed by one step is performed (step S170). Thereafter, or if it is determined that the processing speed has already reached the maximum speed, the process returns to step 120 and the process is repeated from determination as to whether or not a payout is detected within a predetermined time. By this processing, as shown in section 1 in FIG. 9, as long as the payout of the pachinko ball is detected within the predetermined time t1, the driving speed gradually increases, and the driving is eventually performed at the maximum speed. Thereafter, if the payout of the pachinko balls continues, the payout at the maximum speed is continued. This state is shown as section 2 in FIG.

On the other hand, there are conditions under which the payout of pachinko balls cannot be continued. For example, not only troubles such as occurrence of jamming or biting of the balls in the delivery device 20 but also a situation in which supply of pachinko balls that can be paid out as a prize ball is delayed, and the ball supply interlock switch 15 detects such a state. Can be In such a case, the payout of the pachinko ball cannot be detected, and the determination in step S120 is “NO”. In this way, if the payout cannot be detected within the predetermined time t1 even if the stepping motor 50 is driven,
It is determined whether the drive speed of 0 is the minimum speed (step S180).
A step-down process is performed (step S190). As a result, if the state in which the payout of the pachinko balls cannot be detected continues, the driving speed of the stepping motor 50 gradually decreases as shown as the section 3 in FIG.

Since a decrease in the driving speed usually results in an increase in the driving torque, in the case of a pachinko ball which is difficult to move due to friction or the like, when the driving speed gradually decreases, the ball cutting plate 41 starts to move, and the pachinko ball is paid out. There are many things. As a result, the payout of the pachinko ball is detected (Step S).
120), the drive speed is also increased. When the driving speed is increased, the driving torque generally decreases, so that the pachinko balls are not sent out, and the driving speed decreases again. That is, in this state (FIG. 9, section 4), the drive speed is repeatedly increased and decreased. If the factor that hindered the payout of the pachinko balls is completely eliminated, the pachinko balls will be discharged one after another, and the driving speed will also increase. This situation is shown as section 5 in FIG.

After the pachinko balls are not discharged and the driving speed of the stepping motor 50 is gradually reduced to the minimum speed (section 6 in FIG. 9), no payout is detected even after the time t2 has passed (steps S120 and S180). Then, it is determined whether or not the flag Fr is 1 (step S20).
0). Since the value of the normal flag Fr is set to 0, the determination in step S200 is “NO” and the time t
2 is determined (step S2).
10). If the payout of the pachinko balls cannot be detected even after the stepping motor 50 is held at the minimum speed for the predetermined time t2, it is determined that a clogging or the like has occurred in the delivery device 20, and then the stepping motor 50 is stopped for the time t3. Is reversed (step S22).
0), and immediately thereafter, a process of setting the value of the flag Fr to 1 to indicate that the reverse rotation control has been performed (step S)
230). After the reverse rotation control is performed for a predetermined period by the process of step S220, the stepping motor 50 is again rotated in the forward direction at the minimum speed.

Normally, the pachinko ball that has been bitten or clogged is released from the state of clogging and the like by the reverse rotation of the ball cutting plate 41 due to the reverse rotation of the stepping motor 50, and the normal rotation of the stepping motor 50 is continued. The paper is discharged from the delivery device 20 by the forward rotation). Therefore, the stepping motor 5 in the section 7 shown in FIG.
After the reverse rotation of 0, when the stepping motor 50 rotates forward,
The payout of the pachinko ball is detected (step S120),
The remaining number i of prize balls is decremented (step S13)
0), the drive speed of the delivery device 20 is gradually increased (section 8 in FIG. 9). On the other hand, if the payout of the pachinko ball cannot be detected after the stepping motor 50 is once reversed, it is determined that a serious failure may have occurred, and an alarm process is performed (step S240). To end.

When such a failure does not occur and the payout of the pachinko balls is continued and the payout of the predetermined number S of the pachinko balls is completed, it is determined whether or not the remaining number of the winning balls is present (step S260). If there is a remaining number, it is determined that payout is to be continued, a predetermined value S is set to the variable i again, the process returns to the payout detection process (step S120), and the above process is repeated from here. As a result,
Since it is not necessary to drive the delivery device 20 again from the minimum speed, it is possible to pay out the prize balls efficiently. In addition,
If there is no remaining winning ball, the process directly goes to "END" and the processing routine ends. As a result, the delivery device 20 stops.

FIG. 8 is a graph showing the state of the driving power when the driving speed increases or decreases. As shown in the figure, when the payout of the pachinko balls is detected and the drive speed is increased by one level (section 11), the drive power is rapidly increased for a short period of time and thereafter is maintained at a predetermined level determined by the drive speed. When the driving speed reaches the maximum, the driving power is kept constant (section 12). When the drive speed is decreased, as in the case of increase, the drive power is temporarily increased to increase the torque, and then maintained at a predetermined level determined by the drive speed (section 13). By controlling in this way,
Obtaining a large driving torque and a stepping motor 5
This prevents both heating of 0.

Even when steady driving is performed, the maximum driving power Pmax and the minimum driving power Pmin are similarly combined to obtain an average driving power PAV, as shown in FIG. Is controlling. When the maximum drive power Pmax is applied, the delivery device 20 starts to move against the frictional force and inertia due to the maximum static friction coefficient of each part and the pachinko ball, while the drive device 20 is driven by the average drive power PAV as a whole. As a result, unnecessary heat generation or the like does not occur.

According to the pachinko ball feeding apparatus of the present embodiment described above, the stepping motor 50 is reduced while using the small stepping motor 50 to reduce the size of the apparatus.
The feeding of the pachinko balls by the above can be ensured. Also, since the size of the device can be reduced,
It is also possible to facilitate installation in a narrow space on the back of the pachinko machine, improve design flexibility, and the like. In this embodiment,
The size of the motor could be reduced to about 1/2 in volume ratio.

Further, in this embodiment, the payout of pachinko balls is monitored, and when the payout is performed continuously, that is, when the payout condition is good, the payout speed is increased and the payout cannot be performed. For example, when the payout condition is poor, the payout speed is reduced to increase the driving torque, and the payout of the pachinko balls is further ensured. Further, in this embodiment, the stepping motor 50 is used as the driving source. However, unlike the DC motor, the stepping motor is unlikely to cause a trouble such as continuing to rotate due to a short circuit or the like, and is not reliable as a pachinko ball feeding device. The nature is high.

In this embodiment, the driving speed is controlled based on the detection of the payout by the prize ball confirmation switch 19. However, when the ball supply interlock switch 15 detects that the supply of the ball cannot keep up, the driving speed is controlled. And the payout of the prize ball can be made uninterrupted.
In this case, the payout of the prize ball is not interrupted, so that the player does not feel uncomfortable. Also, since the ease of paying out pachinko balls varies depending on the environment of the pachinko machine, for example, temperature and humidity, the higher the humidity, the lower the maximum drive speed and the more secure the drive torque that can be paid out.
It is also possible to control the payout speed to the optimum.

In addition, when a jam is detected by the jam interlock switch 17, the payout can be stopped and an alarm process can be performed. Further, when it is detected by the upper and lower plate interlock switch 27 that the prize ball on the receiving tray is overflowing, the payout speed of the prize ball can be reduced or the payout itself can be stopped.

In this embodiment, the delivery device 2 is controlled based on a signal from the start switch 24 (a detection signal of a winning ball).
0 is driven to pay out a predetermined number (7 or 15) of pachinko balls as prize balls. However, a ball lending switch is provided on the pachinko machine, a predetermined fee is paid, and the ball lending switch is pressed. In this case, the pachinko ball delivery control device according to the present embodiment can pay out a different number of pachinko balls from the prize balls. For example, it is easy to rent out 25 pachinko balls by operating the ball lending switch once. In addition, it is also possible to rent out a predetermined number of pachinko balls determined by an integer multiple of 25 or a look-up table or the like according to the amount of money put in for lending.

The embodiment of the present invention has been described above.
The present invention is not limited to such an embodiment. For example, a configuration using another motor such as a DC motor as a driving source, a configuration using a three-phase or more multi-phase stepping motor, or a pachinko ball lending device Of course, the present invention can be implemented in various modes without departing from the gist of the present invention, such as a configuration used in a device for counting the number of pachinko balls.

As described above in detail, according to the pachinko ball of dispensing apparatus of the present invention, based on the supply state or the discharge state of the pachinko balls to the pachinko ball discharge mechanism, Pachi
Increasing / decreasing the operating state of the ball discharge mechanism in multiple stages
Since that, an excellent effect of being able to perform the delivery of pachinko balls reliably and fast. As a result, there is an excellent effect that both the downsizing of the pachinko ball delivery device and the improvement of the accuracy of the delivery of the pachinko balls can be achieved.
