Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a pachinko ball supply device for a pachinko machine.

PRIOR TECHNOLOGY There are various types of pachinko ball replenishment devices used in pachinko game parlors, but the main part of the mechanism for replenishing a set number of balls is generally a pachinko ball 4 (hereinafter simply referred to as "ball") as shown in Fig. 9. A ratchet wheel 6 is peeked into the replenishment passage 5a of the ratchet wheel 6, and a disc (not shown) is rotated by the ratchet wheel 6 when the number of revolutions of the ratchet wheel 6 due to the falling of the ball reaches a certain number. A pawl (not shown) provided on the frame of this setting device is inserted into the formed notch, and this pawl wheel 6 is stopped, thereby stopping the supply of balls and setting the ball in advance. It is designed to supply a certain number of balls. (Refer to Japanese Patent Publication No. 57-35026-7 ``Automatic Pachinko Ball Replenishing Device in Pachinko Machine'').

However, the above device uses a fixed number of balls (generally
400 pieces), it was difficult to adjust the specified number of stops.

For example, even if the ball tank installed at the top of a pachinko machine becomes empty and the designated number of balls remains to be reached with 100 balls remaining, 400 balls must be replenished.

Also, what is shown in Figures 10 and 11 relates to a single ball replenishing device that uses an electromagnetic solenoid instead of the control mechanism that uses the ratchet wheel. indicates the main part of the control device.

In FIG. 11, by operating the solenoid 14 and sucking or restoring the stopper 3a, balls falling down the ball supply passage 5 can be supplied one by one, and the balls can be supplied to the ball tank as in the above-mentioned supply device. This is a replenishment device that allows replenishment of individual items without being limited to a fixed number of 400 items. (Refer to Utility Model Publication No. 15583/1983, "Pachinko ball feeding device") Problems that the invention aims to solve Since the amount is limited, it is difficult to replenish the number specified for discontinuation, and
The mechanism is also complicated, requiring more labor and expense for maintenance, and also occupies a larger area within the machine.

In addition, in a single ball replenishment device using an electromagnetic solenoid, it is necessary to attract the stopper of the electromagnetic solenoid against the force of the spring while replenishing the ball tank, and the solenoid must be kept in operation during this time. (generally 24V x 0.4A≒
10W), as the number of units increases, the amount of power used also increases.
Therefore, a thick electric wire with a large capacity must be used for the power supply line.

Furthermore, ball replenishment devices that use a ratchet wheel may suffer from damage or missing mechanical parts such as the claws of the ratchet wheel or gear teeth, and ball replenishment devices that use an electromagnetic solenoid may suffer from spring fatigue or electromagnet failure. Due to dust clogging in the gap between the plungers, etc., the ball supply passage becomes unstable or insufficiently blocked.
Stopping ball supply becomes unstable or impossible, making it difficult to supply the set number of balls.

The purpose of this invention is to solve the above problems, to create a small and inexpensive product that has a single unit replenishment function, consumes little electricity, and can quickly detect abnormal situations that make it impossible to stop replenishment or stop replenishment. The object of the present invention is to provide a pachinko ball feeding device.

Means to solve the problem This idea uses a latching solenoid instead of the conventional electromagnetic solenoid, and a stopper is fixed to the tip of the plunger of the latching solenoid, so that the stopper moves in and out of the pachinko ball supply path. A latching solenoid that can be freely moved,
Providing means for controlling the stopper,
The apparatus is also provided with means for detecting an abnormal state in which pachinko balls pass through the replenishment passage even though a pachinko ball replenishment stop signal is sent to the control means of the stopper.

Function In general, the plunger of a latching solenoid operates by passing an instantaneous current (pulse current) through its coil for both suction and recovery operations, and even after the current is cut off, the plunger does not change its position. It will be retained as is.

Therefore, unlike general electromagnetic solenoid coils, there is no need for mechanisms such as a holding current during attraction or a spring for recovery.

The basic structure of the means for controlling the stopper provided on the latching solenoid is shown in the block diagram of the electrical connection system in FIG.

When the ball tank at the top of the pachinko machine becomes empty, it receives a replenishment signal sent from the central control room and sends it to the latching solenoid, which suctions and holds the stopper to start replenishing balls and set the number of balls to be replenished. When the specified number is reached, a signal is automatically sent to the latching solenoid to restore and hold the stopper to close the ball supply device and stop supplying balls.

In addition, if an abnormal condition occurs in which the operation of the stopper becomes unstable and the ball replenishment cannot be stopped due to dust clogging in the gap between the electromagnet and the plunger, electrical noise, etc., an abnormality will be detected. A warning can be issued by means, and a formula can prevent the flow of water in a minimum unit.

Embodiment To explain one embodiment of this invention, Fig. 1 is a diagram showing changes in the operating status of the latching solenoid provided in the ball supply path, and Fig. a shows the plunger 2 of the latching solenoid 1 being sucked and held. Figure b shows the situation where the plunger is restored and held and the passage of the ball is stopped, and Figure c shows the situation where the plunger is restored and held unstable and the supply is stopped. Indicates a situation where it is impossible. Figure 2 is a block diagram showing the electrical connection system of this device.
As mentioned above, this is a known method.

That is, detecting pachinko balls passing through the supply path 5,
A detector that sends pulse signals to a counter, a counter that receives pulse signals from the detector, counts and organizes them, and outputs this value to a comparator circuit, and a predetermined supply of one pachinko ball to the comparator circuit. Setting device for inputting ball values.

a comparison circuit that compares the numerical value input from the counter with the numerical value set by the setting device and sends a replenishment stop signal to the control circuit when they match;
Receives the replenishment signal sent from the central control room and the signal from the comparison circuit, and in response to each signal, the stopper 3 provided on the latching solenoid is activated.
It is composed of a control circuit that sends a held signal to the latching solenoid 1, an abnormality detection circuit, an abnormal replenishment suppression circuit, and a power supply section that supplies power to each of the above circuits.

Now, when the ball tank installed at the top of the pachinko machine is empty, a switch installed on the outer wall of the ball tank is closed, and a detector for the number of balls to be replenished is activated (not shown as it is publicly known), and the main control room is closed. A replenishment start signal e of a pulse current having a waveform shown in FIG. 3 is sent to the latching solenoid 1 from the control circuit which receives the replenishment signal from the latching solenoid 1.

The latching solenoid 1 sucks and holds the plunger 2 and the stopper 3 in response to the supply start signal e, so that the ball supply passage 5 is opened and the supply of balls into the tank is started.

Regarding the following actions, through the same process as above, balls are replenished from the central storage chamber until the number of balls matches the set number, and when the number matches, the plunger 2 is automatically restored and held to resume the supply. will be stopped.

Figure 3 shows a time chart of each signal sent in and out from each of the above circuits, e is a replenishment start signal sent from the control circuit to the latching solenoid in response to replenishment signal b from the central control room, m is e A signal sent from the control circuit that receives the signal to the latching solenoid 1 to attract and hold the plunger 2, a
is a signal sent from the detector to the counter at the same time as the supply of balls starts, and l is a signal sent from the comparison circuit to the control circuit when the setting value input by the setting device and the input value from the counter match in the comparison circuit. In response to the l signal, the control circuit sends a signal to the latching solenoid 1 to restore and hold the plunger 2.

In addition, as means for detecting an abnormal state in which balls 1 continue to be replenished when supply of balls 1 is stopped, one or both of the abnormality detection circuit shown in FIG. 4 or the abnormal supply suppression circuit shown in FIG. 6 can be used. are arranged in parallel as shown in Figure 2.

FIG. 4 is a block diagram of an abnormality detection circuit as an embodiment of the abnormality detection means, and FIG. 5 shows its waveform diagram.
Connect to the S terminal of the flip-flop circuit, R-S
A replenishment start signal e, a ball detection signal (sensor signal a), and a replenishment signal b are input to the R terminal of the flip-flop and the input terminals 7 and 8 of the NOR gate, respectively.
The configuration is such that the output terminal Q of the R-S flip-flop circuit extends to the alarm device.

Normally, the R-S flip-flop is reset and its output is at the L level, and if the suction and holding operations of the plunger 2 are normal, the replenishment path is opened only during the H level when the replenishment signal b is transmitted. Every time the ball passes, the sensor signal a sent from the detector changes from H level to L level.
The output signal c of the NOR gate, which is input from the input terminal 8 of the NOR gate, is normally at L level, but the operation of the plunger 2 of the solenoid 1 is defective or unstable, and a ball appears as shown at 1-3 in Figure 1. In an abnormal state in which stoppage of supply is impossible, supply of balls continues even if the ball supply signal b reaches the supply stop state L level, so the sensor signal a continues to be output.

At this time, the output sensor signal a (L level)
Then, the supply signal b at the L level is inputted from the input terminals 8 and 9 of the NOR gate, so the output signal c becomes H level and inputted to the S terminal of the R-S flip-flop circuit, and at the same time, the input signal from the R terminal is inputted from the R terminal. Since the replenishment start signal e is at the L level, the output of the R-S flip-flop, that is, the error detection signal d, goes to the H level, and the error detection signal d is sent to the alarm device connected to the Q terminal, and the error detection signal d is sent to the alarm device connected to the Q terminal. Abnormal conditions can be reported.

Furthermore, by connecting a counter to the output terminal 7 of the NOR gate, it is possible to detect the number of balls replenished in excess of the set number.

FIG. 6 shows another embodiment of the abnormality detection means, which detects the abnormality when the plunger 2 of the latching solenoid 1 is unable to recover and maintain the state when the supply of balls is stopped, and the ball flows out. FIG. 7 is a block diagram of an abnormal replenishment suppression circuit having a function of suppressing the number of replenishments to a minimum of one, and FIG. 7 is a waveform diagram thereof.

Its configuration consists of an OR gate, an AND gate, a monostable multivibrator, and a driver connected in series, and the output signal of the monostable multivibrator is passed through the driver to the latching solenoid.
In addition, a trigger pulse generation circuit consisting of a resistor R and a capacitor C is connected to the replenishment signal input terminal 10 of the AND gate.

Next, to explain this effect, if ball replenishment continues even after the ball replenishment signal stops being emitted and reaches the L level, the sensor signal a is sent out from the detector.
Respective signals are input from input terminals 12 and 13 of the OR gate, and the output of the OR gate becomes an error signal f and is transmitted to the input terminal 11 of the AND gate.

Further, as shown in the waveform diagram of FIG. 7, the AND gate input terminal 8 receives the trigger signal g generated by the trigger pulse generating circuit at the falling edge when the replenishment signal b is stopped.

The pulse width of the trigger signal g is determined by the values of the resistor R and capacitor C, and the diode D is
It is for gate protection.

When the error signal f from the OR gate is input to the input terminal 7 of the AND gate following the trigger pulse signal g, the error signal h is sent from the AND gate to the monostable multivibrator, and the error signal h is further transmitted to the monostable multivibrator. A pulse current i shaped into a square wave by the vibrator is sent to the driver.

The driver receives the pulse current i, amplifies it, sends it to the latching solenoid 1, re-drives the plunger 2, and reliably restores and holds the ball, thereby stopping the supply of balls. Abnormal replenishment exceeding the specified number of replenishments can be suppressed to a minimum of one replenishment.

Figure 8 shows an example of a backup circuit that temporarily supplies power to each circuit in place of the main power supply when the power supply from the main power supply is stopped due to a commercial power outage. A diode A and a diode B are connected in series between the main power supply and a power supply source (not shown) that connects each circuit section, and one end of a resistor R is connected to the connection between A and B. The other end is connected to the (+) terminal of the battery D, and the (-) terminal side is grounded.

Under normal conditions, power is supplied from the main power source to each circuit device through diodes A and B, and at the same time, a charging current is passed through resistor R to battery D to charge battery D.

When the supply of main power is temporarily stopped due to a power outage or the like, power is supplied from battery D to each circuit and device via resistor R and diode B.

At this time, since the circuits and devices described above are used as circuits and devices for controlling the latching solenoid, the amount of power used is relatively small, and even with a small capacity resistor R and battery D, the power consumption is short, but the pachinko machine Power can be supplied so that there is no problem with the operation of the

Effects of the invention This invention provides a latching solenoid so that the plunger of the latching solenoid can move in and out of the pachinko ball supply path as described above.
By providing a means for controlling the operation of the plunger, it is possible to arbitrarily set and change the supply quantity for each ball, and it is also possible to provide a small-sized pachinko ball supply device that consumes less power.

Furthermore, by providing an abnormality detection circuit or an abnormal replenishment prevention circuit in the means for controlling the operation of the plunger, when the operation of the plunger becomes defective, it is possible to immediately warn of the occurrence of an abnormal state of the pachinko ball replenishment device. , abnormal replenishment of balls can be suppressed to the minimum unit.

Furthermore, this device is used not only to replenish the ball tanks of each pachinko machine from the ball storage room in the store, but also to replenish the prize ball tanks from the ball tanks of each pachinko machine.
It can also be used to replenish balls for ball lending machines.
