Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko ball delivery control device, and more particularly to a pachinko ball delivery control device that sequentially delivers pachinko balls using an electric motor as a drive source.
[0002]
[Prior art]
Conventionally, in this type of pachinko ball delivery control device, pachinko balls gathered 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 the control means, and the pachinko ball's own weight is controlled. Thus, a feeding device that sends out pachinko balls one by one and a control device that simply controls on / off of the same are used. In such a configuration, there is a problem in that the ball counting accuracy / feeding speed is low, and if a failure occurs while the stopper or the like is open, the ball continues to protrude. Therefore, in order to solve this, an electric motor such as a DC motor is used as a drive source, and a ball cutting disk having a notch into which a pachinko ball can be fitted on the outer circumference is provided so that the outer circumference faces the ball path, and according to a winning signal There has been proposed a device that uses a device for rotating a lever cutting disk by a predetermined angle to feed out a necessary number of pachinko balls (Japanese Patent Laid-Open No. 63-164977).
[0003]
[Problems to be solved by the invention]
However, in the case of adopting a configuration in which a pachinko ball is discharged by rotation using an electric motor, there is a problem that the entire apparatus becomes large because the electric motor is used. However, if the electric motor is simply downsized, the driving force may be insufficient, and the reliability for reliably delivering the 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. Moreover, the conditions under which the pachinko balls can be reliably discharged differ depending on the condition of the balls before and after the delivery mechanism, and the conditions such as environmental temperature and humidity.
[0004]
Furthermore, in the case of a pachinko ball feeding mechanism, it is extremely difficult to completely avoid an unexpected situation such as biting of the pachinko balls. In such a case, a configuration that reliably discharges the pachinko balls 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 the reliability.

In the following description, only one is shown because of the same configuration. The configuration and operation of the ball confirmation switch 18 and the prize ball confirmation switch 19 will be described in detail later together with the configuration and operation of the delivery device 20.
[0013]
The sending out of the prize balls by the sending-out device 20 is performed according to the winning ball, and this winning ball is detected by the detector 24 provided in the winning ball lead-out path 23. The winning balls are classified into three according to the type of the winning combination, and three sets of detectors 24 are also provided. This is called a first, second and third start switch (24a, b, c) in the sense of a signal for starting the delivery of the pachinko ball.
[0014]
Below the delivery device 20, the pachinko balls counted and released by the delivery device 20 are discharged to the upper plate (reference numeral 33 in FIG. 1) and the lower plate (reference numeral 34 in FIG. 1) provided on the front surface of the front frame 3.

Yes.
[0015]
Next, the configuration of the delivery device 20 will be described. As shown in FIGS. 3 and 4, the delivery device 20 has a hollow rectangular tube-shaped case 29 opened up and down, and two rows of balls at a position corresponding to the lower end of the lead rod 12 inside. Passages 31 and 32 are provided. In addition, a horizontal shaft 35 whose both ends are supported by the wall surface of the case 29 is provided inside the case 29, and two slicing disks 41, 42 are integrated with the horizontal shaft 35 by the connecting cylinder portion 43 and the horizontal shaft 35. It is pivotally supported with respect to the shaft.
[0016]
Each of the ball cutting disks 41 and 42 includes two sprockets 44 having semicircular cutouts Pa at 13 locations on the outer periphery, and a bracket 45 that fixes the sprockets 44 on both sides. As shown in FIG. 4, the ball cutting discs 41 and 42 are provided at positions where the outer circumferences face the inside of the ball passages 31 and 32. Further, since the diameter of the notch Pa provided on the outer periphery of the sprocket 44 is substantially the same as that of the pachinko balls, when the ball cutting discs 41 and 42 are rotated, the pachinko balls B in the ball passages 31 and 32 are one by one. Then, it is sent out to the discharge rod 26. The ball cutting disks 41 and 42 are fixed to each other at a rotational position shifted by exactly ½ of the pitch of the cutout Pa, and the pachinko balls are alternately sent out.
[0017]
A worm gear 46 is fixed to the outer periphery of the connecting cylinder portion 43 that connects the two sets of the ball cutting discs 41 and 42. A worm 47 for driving the worm gear 46 is engaged with the worm gear 46. One end of the shaft 49 to which the worm 47 is attached is rotatably supported on the outer wall of the case 29, and the other end is fixed to the rotating shaft 51 of the stepping motor 50. The stepping motor 50 is fixed to the outer wall of the case 29. When the stepping motor 50 rotates, the worm gear 46 rotates through the rotation of the worm 47 directly connected to the rotating shaft 51, and the ball cutting disks 41 and 42 also rotate. In order to detect the state of rotation of the ball cutting disks 41 and 42, a transmission type photodetector 55 using infrared light is provided at a position sandwiching one sprocket 44 of the ball cutting disk 42. The transmission type photodetector 55 sends out a pulse signal from the notch Pa of the sprocket 44 every time light is transmitted or blocked, that is, every time one pachinko ball is sent out.
[0018]
The mounting position relationship between the delivery device 20 and the ball confirmation switch 18 and the prize ball confirmation switch 19 will be described. As shown in FIG. 4, the ball confirmation switch 18 is located immediately before the ball paths 31 and 32 of the delivery device 20. The prize sphere confirmation switch 19 is provided immediately below.
[0019]
Next, a configuration around the electronic control device 60 that controls the entire pachinko machine and the delivery device 20 that is controlled by the electronic control device 60 will be described with reference to FIG. This electronic control unit 60 is mainly composed of a well-known arithmetic logic unit, ROM, RAM and the like. The electronic control device 60 takes in signals from the various switches described above, and controls the sending device 20 or a display element group such as a winning display lamp (not shown).
[0020]
Various switches such as a ball replenishment interlock switch 15, a ball jam interlock switch 17, a ball confirmation switch 18, a prize ball confirmation switch 19, a first, a second and a third start switch 24, and a top and bottom dish interlock switch 27 are electronic. The control device 60 is connected to the input port, and the ball launching device 14 and the stepping motor 50 of the delivery device 20 are connected to the output port. In the electronic control device 60, interface circuits corresponding to these switches and external devices are provided, but illustration and description thereof are omitted here.
[0021]
The configuration of the ball check switch 18 and the prize ball check 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 the composition of. Therefore, taking the ball check switch 18 as an example, the configuration of these switches and the electronic control device 60, the connection with the electronic control device 60, and the principle of detection of a pachinko ball will be described. As shown in FIG. 5, the ball confirmation switch 18 and the prize ball confirmation switch 19 include a casing 71 having a U-shaped cross section, and a substrate 73 therein. One end of the substrate 73 protrudes out of the casing 71 and is used as the 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 portions 81 and 82 of the U-shaped casing 71. The distance between the centers of the storage portions 81 and 82, that is, the distance between the centers of the coils L1 and L2 is a pachinko ball. The distance is just 1.5 times the diameter of B.
[0022]
As shown in FIG. 6, the ball check switch 18 includes a power supply terminal T <b> 1 to which 12 volts is supplied and a detection terminal T <b> 2 connected to the input port PB <b> 1 of the electronic control device 60. The detection terminal T2 also serves as the ground level of the circuit, and is grounded via the resistor RD on the electronic control device 60 side.
[0023]
The ball check switch 18 includes a high-frequency oscillation circuit CO and a switching circuit SW that is turned on / off based on the oscillation state of the high-frequency oscillation circuit CO. 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 C1 interposed between both emitters of the double transistor Tr1 and the ground line. , C2 and coils L1, L2 constitute a Colpitts-type high-frequency oscillation circuit. Note that the base of the double transistor Tr1 is connected to the power supply line via the resistor R2. When the pachinko ball B is not approaching the coils L1 and L2, the high-frequency oscillation circuit CO oscillates at an oscillation frequency determined by the inductances of the coils L1 and L2 and the capacitances of the capacitors C1 and C2. The oscillation frequency in this embodiment is about 300 KHz. When the pachinko ball B approaches one of the coils L1 and L2, an eddy current is generated inside the pachinko ball B by the magnetic flux generated by the coils L1 and L2, and this eddy current loss attenuates the oscillation of the high-frequency oscillation circuit CO. Stop.
[0024]
The switching circuit SW connected to the collector terminal of the double transistor Tr1 of the high-frequency oscillation circuit CO is configured with the transistor Tr2 as the center, and the transistor depends on whether the double transistor Tr1 is oscillating or stopped. Tr2 is turned on or off. 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 (resistance value 680Ω in this embodiment), the transistor Tr2 Depending on the state, the voltage of the detection terminal T2 changes. The electronic control unit 60 can detect the state of the ball check switch 18 based on the change in voltage.
[0025]
This point will be described in some detail. Since the resistor R4 connected to the emitter terminal of the transistor Tr2 has a resistance value smaller than that of the power supply terminal T1 resistor R1 (220Ω: 27 KΩ in this embodiment), when the transistor Tr2 is turned on, the resistor Tr4 is turned on from the power supply terminal T1. , The current flowing through the Zener diode D1 through the resistor R4 is larger than the current flowing through the resistor R1 (approximately 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 device 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 can easily know the state in which the ball check switch 18 detects the pachinko ball B (low level) and the state in which it does not detect (high level) by monitoring the state of the input port PB1. Can do.
[0026]
The coils L1 and L2 of the ball check switch 18 have a center-to-center distance DL of 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 a position 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 in contact with each other, even if the entire pachinko ball is moving, eddy current loss is caused by either the magnetic flux of the coils L1 and L2, and the high-frequency oscillation circuit CO always oscillates. The transistor Tr2 of the switching circuit SW is turned off, and the input port PB1 of the electronic control device 60 is at a low level.
[0027]
On the other hand, since the coil L2 does not exist in the prize ball check switch 19, the oscillation of the high-frequency oscillation circuit CO is interrupted every time the pachinko ball B passes, and the pachinko ball passes continuously in a fairly close state. Even so, the detection terminal T2 becomes a low level for a short time in response to the passage of one pachinko ball B. Therefore, the electronic control unit 60 can individually detect the passage of the prize sphere and count it by monitoring the level of the input port PB2.
[0028]
Processing executed by the electronic control device 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 prize 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 in the variable i. Then, the process which controls the stepping motor 50 of the sending-out apparatus 20 to the minimum drive speed is performed (step S110). Since a large driving force is required when starting the stepping motor 50, a large driving power is applied as shown in FIG.
[0029]
Subsequently, it is determined whether or not the pachinko ball has been paid out within a predetermined time t1 (step S120). When the stepping motor 50 is driven at the minimum driving speed and the ball cutting plate 41 rotates and the pachinko balls are normally fed out, the prize ball check switch 19 detects this, and based on this signal, the payout of the pachinko balls is confirmed. Is done. When the payout is detected within the predetermined time t1, the variable i indicating the remaining number of prize balls is decremented by 1 (step S130), and the pachinko ball is paid out normally. The value 0 is set to the flag Fr (step S140).
[0030]
Thereafter, it is determined whether or not the variable i has a value of 0 (step S150). If it is determined that the value sphere is not 0, that is, a prize ball that has not been paid out still remains, the driving speed of the stepping motor is set. It is determined whether or not the speed is the maximum speed (step S160). If it is determined that the speed is not yet the maximum speed, 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 the determination of whether or not a payout is detected within a predetermined time. By this process, as shown as section 1 in FIG. 9, as long as pachinko ball payout is detected within a predetermined time t1, the driving speed gradually increases, and the driving speed is eventually reached. Thereafter, if the pachinko ball is continuously dispensed, the dispensing at the maximum speed is continued. This state is shown as section 2 in FIG.
[0031]
On the other hand, there are conditions under which pachinko balls cannot be paid out. For example, not only troubles such as the occurrence of clogging or ball biting in the delivery device 20, but also the situation where the supply of pachinko balls that can be paid out as a giveaway ball is delayed and the ball supply interlock switch 15 or the like detects such a state. It is done. In such a case, the payout of the pachinko balls cannot be detected, and the determination in step S120 is “NO”. Thus, if the payout cannot be detected within the predetermined time t1 even if the stepping motor 50 is driven, it is determined whether or not the driving speed of the stepping motor 50 is the lowest speed (step S180). The drive speed is reduced by one step (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 section 3 in FIG.
[0032]
Since a decrease in drive speed usually results in an increase in drive torque, in the case of pachinko balls that are difficult to move due to friction or the like, the ball cutting plate 41 starts to move when the drive speed gradually decreases, and the pachinko balls are often paid out. . As a result, the payout of the pachinko balls is detected (step S120), and the driving speed is also increased. When the driving speed is increased, the driving torque generally decreases, so 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 hinders the payout of the pachinko balls is completely removed, the pachinko balls are discharged one after another, and the driving speed increases. This is shown as section 5 in FIG.
[0033]
After the pachinko balls are not discharged and the driving speed of the stepping motor 50 is gradually reduced toward the minimum speed (section 6 in FIG. 9), no payout is detected after the time t2 (steps S120 and S180). Then, it is determined whether or not the flag Fr is 1 (step S200). Since the normal flag Fr is set to the value 0, the determination in step S200 is “NO”, and further, it is determined whether or not the time t2 has elapsed (step S210). If the pachinko ball payout cannot be detected even if the stepping motor 50 is held at the minimum speed for the predetermined time t2, it is determined that the ball clogging or the like has occurred in the feeding device 20, and then the stepping motor 50 is performed for the time t3. (Step S220), and immediately after that, a process of setting a value 1 to the flag Fr is performed to indicate that the reverse rotation control has been performed (step S230). In addition, after performing reverse rotation control for a predetermined period by the process of step S220, the stepping motor 50 is rotated again in the normal rotation direction at the minimum speed.
[0034]
Normally, the pachinko balls that have been bitten or clogged are cleared 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 (forward rotation) of the subsequent stepping motor 50 continues. As a result, it is discharged from the delivery device 20. Accordingly, when the stepping motor 50 rotates in the forward direction after the reverse rotation of the stepping motor 50 in the section 7 shown in FIG. 9, the payout of the pachinko ball is detected (step S120), and the remaining number i of the prize balls is decremented (step S130). ), The driving 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 reversed once, an alarm process is performed assuming that a serious failure may have occurred (step S240), and this process routine Exit.
[0035]
When there is no such failure and the pachinko balls are continuously paid out and the payout of the predetermined number S of pachinko balls is completed, it is determined whether or not there is a remaining number of winning balls (step S260). In some cases, it is assumed that the payout is to be continued, the predetermined value S is set again in the variable i, the process returns to the payout detection process (step S120), and the above-described process is repeated from there. As a result, since it is not necessary to drive the delivery device 20 again from the minimum speed, it is possible to efficiently pay out the prize sphere. If there is no remaining number of winning balls, “END” is left as it is, and this processing routine is terminated. As a result, the delivery device 20 stops.
[0036]
FIG. 8 is a graph showing the driving power when the driving speed is increased or decreased. As shown in the figure, when the payout of the pachinko ball is detected and the driving speed is increased by one step (section 11), the driving power is rapidly increased for a short period, and thereafter maintained at a predetermined level determined by the driving 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 the 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 both large driving torque and preventing the stepping motor 50 from being heated are compatible.
[0037]
Even when steady driving is performed, as shown in FIG. 10, in order to obtain an average driving power PAV, the stepping motor 50 is similarly controlled by combining the maximum driving power Pmax and the minimum driving power Pmin. ing. When the maximum drive power Pmax is applied, the feeding device 20 starts to move against the frictional force and inertia due to the maximum static friction coefficient of each part of the device and the pachinko balls, while the drive device 20 as a whole is driven by the average drive power PAV. As a result, unnecessary heat generation or the like does not occur.
[0038]
According to the pachinko ball delivery device of the present embodiment described above, the pachinko ball delivery by the stepping motor 50 can be ensured while using the small stepping motor 50 while downsizing the device. In addition, since the apparatus can be reduced in size, it is possible to facilitate the installation in a narrow space on the back surface of the pachinko machine and improve the degree of design freedom. In this embodiment, the size of the motor can be reduced to about ½ of the conventional volume ratio.
[0039]
Further, in this embodiment, the payout of the pachinko balls is monitored, and when the payout is continuously performed, that is, when the payout condition is good, the payout speed is increased and the payout cannot be made. When the conditions are bad, the payout speed is reduced to increase the drive torque, and the pachinko balls are paid out more reliably. In this embodiment, the stepping motor 50 is used as a drive source. However, unlike the DC motor, the stepping motor is unlikely to continue to rotate due to a short circuit or the like, and is reliable as a pachinko ball feeding device. The nature is high.
[0040]
In this embodiment, the driving speed is controlled based on the detection of the payout by the prize ball confirmation switch 19, but the driving speed is lowered when the ball supply interlock switch 15 detects that the supply of the ball cannot catch up. It is also possible that the payout of the prize ball is not interrupted. In this case, since the payout of the prize ball is not interrupted, the player does not feel uncomfortable. Also, because the ease of paying pachinko balls varies depending on the environment of the pachinko machine, for example, temperature and humidity, the maximum drive speed is controlled by reducing the maximum drive speed as the humidity increases to ensure the drive torque that can be discharged reliably. It is also possible to do.
[0041]
In addition, when a clogging is detected by the clogging interlock switch 17, it is possible to stop the payout and perform an alarm process. Further, when it is detected by the upper / lower tray interlock switch 27 that the prize sphere in the tray is overflowing, it is possible to reduce the payout speed of the prize sphere or to stop the payout itself.
[0042]
In this embodiment, the feeding device 20 is driven based on a signal from the start switch 24 (a winning ball detection signal) to pay out a predetermined number (seven or fifteen, etc.) of pachinko balls as premium balls. However, when a ball lending switch is provided on the pachinko machine and a predetermined fee is paid and the ball lending switch is pressed, the pachinko ball feeding control device of this embodiment pays a number of pachinko balls different from the prize balls. It can also be taken out. For example, it is easy to lend 25 pachinko balls by operating the ball lending switch once. Further, it is possible to lend a predetermined number of pachinko balls determined by an integer multiple of 25 or a look-up table, etc., according to the amount invested for lending.
[0043]
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, a configuration in which another motor such as a DC motor is used as a drive source, a multiphase stepping motor having three or more phases. Needless to say, the present invention can be implemented in various modes without departing from the gist of the present invention, such as a configuration using the device or a configuration used in an apparatus for counting the number of pachinko balls, such as a pachinko ball lending device.
