Description

[Detailed Description of the Invention] This invention provides a downflow gutter to a part of the supply pipe through which the balls pass in a line from the supply source, and when a predetermined number of balls pass through the gutter, Restrain the flow.

This relates to an improvement in the ball replenishment means, which can arbitrarily adjust the fixed amount of ball replenishment for each pachinko machine based on signals counted according to the peaks of each pachinko machine and the state of ball entry. It is related to the method.

In the illustrated embodiment, a downflow gutter 2 is provided on one side of the substrate 1,
It communicates with the supply pipe 3 and allows the balls to flow down vertically one by one from the bottom outlet of the reserve tank (not shown).

Reference numeral 4 denotes a driving gear wheel in which a ball passing through the downflow gutter 2 engages with a notch 4' and rotates due to the weight of the ball. , and is attached to the support shaft 8 with a part of the notch 4' facing the arc-shaped opening 7 of the downflow gutter 2.

Reference numeral 9 denotes a reduction gear which is attached to the support shaft 10 and meshes with the pinion 5. A control disc 12 is formed on the surface of the reduction gear 9, and a V-shaped locking groove 13 is formed on the periphery. Lid plate 15
is forced to cover the locking groove 13.

The spindles 8 and 10 are also mounted on the board 1.

Reference numeral 16 designates an operating frame fitted onto the support shaft 17, which urges a locking piece 18 clockwise to press against the periphery of the control disc 12, and extends the other end to form a receiving piece 19. It is inserted into the missing part 22 of the excitation rod 21 of the solenoid 20 provided at one corner of the board 1.

Also, 23 is a movable stop rod inserted into the lower part of the operating frame 16,
A through hole 24 is provided near the center of the gear so that it can rotate freely, and is engaged with the notch 4' of the drive gear 4 to restrain reverse rotation or excessive rotation of the drive gear 4.

The ball quantitative replenishment mechanism A having the above configuration is used, and a microswitch 28 is provided above the excitation rod 21 of the mechanism, which is arranged in series with the solenoid 20. 25 is compressed and terminals 26 and 27 are short-circuited.

In such a configuration, when the solenoid 20 is demagnetized, the operating frame 16 is biased clockwise, so the locking piece 18 that is pressed against the control disc 12 is inserted into the locking groove 13. This restricts the rotation of the reduction gear 9 and prevents the balls flowing vertically down the downflow gutter 2 communicating with the supply pipe 3' from passing through.
Figure 4).

However, when the solenoid 20 is energized and excited, the excitation rod 21
is sucked downward, and the receiving piece 19 fitted into the support shaft 17 is moved down following this, and the locking piece 18 is released from the groove 13 (FIG. 5).

Furthermore, the cover plate 15 provided at the tip of the support shaft 10 is biased counterclockwise to cover the groove 13, and even if the solenoid 20 is demagnetized and the locking piece 18 is lowered, it does not fit back into the groove 13 (the second Figure 6)
.

The reduction gear 9 integrally formed with the control disc 12 is
When flowing down in the downflow gutter 2, it engages with the ball and engages with the pinion 5 on the drive gear wheel 4, which rotates due to the weight of the ball, and can freely rotate only in the S direction.

A movable stop rod 23 fitted into a through hole 24 on the support shaft 17 regulates reverse rotation and excessive rotation of the drive gear 4 (FIG. 7), so that only a predetermined number of balls are allowed to pass through.

Now, when the drive gear 4 rotates, it passes through the pinion 5.

The reduction gear 9 follows this and rotates once, and the control disc 12
The locking piece 18 that presses against the peripheral edge of the trough 2 and the cover plate 15 provided at the upper end of the support shaft 10 engage the locking groove 13 in a clockwise direction and restrain the rotation of the drive gear 4. Prevents the ball inside from flowing down.

therefore. The number of balls passing through the downflow gutter 2 is constant depending on the number of notches 4' of the drive gear 4 and the ratio of the number of teeth between the reduction gear 9 and the pinion 5, and only a constant number of balls passing down the flowdown gutter 2 passes through the downflow gutter 2.

The present invention connects one of the terminals 26 and 27 of the microswitch 28 and one end of the excitation wire loop of the solenoid 20 to form a series electric circuit as shown in FIG. When the replenishment signal is applied to the input side of this circuit, the solenoid 20 is excited, attracts the excitation rod 21, and descends in the Q direction, and the push piece 25 is released from pressure (see Fig. 8). ) When the contacts of the microswitch 28 are opened, the electric circuit is opened and the control disc 12 rotates once, after which the locking piece 18 is engaged with the locking groove.

Especially if the width of the locking groove 13 is widened in the counter-rotation direction.

The locking piece 18 fits into the groove 13 before the control disc 12 stops, and the circuit is closed before the ball stops passing.

The diode D1 and capacitor 〇 in Fig. 9 are provided to delay the suction time of the solenoid.

Another embodiment (first example) shown with the same composition as the replenishing device
In Fig. 0), a cam 29 is integrally provided on the back surface of the reduction gear 9, and the push piece 25 of the microswitch 28 is compressed before the locking piece 18 is fitted into the locking groove 13, thereby closing the terminal 26.2.
7 is closed, and as the gear 9 rotates, the terminal 26.
27 is disconnected and the electric circuit is opened again.

The ball replenishment system of the present invention having the above configuration allows passage of a fixed amount of balls with one signal. For example, if the fixed unit amount is 50 balls, replenishment of 300 balls requires 6 signals. The series circuit between the switch and the solenoid is closed before the end of replenishing a fixed amount of balls by one signal, and the next signal is received to supply the next fixed amount of balls in succession. It is to replenish.

Therefore, the replenishment of the set required 300 balls is carried out in a continuous state by receiving signals in sequence.

In short, the series circuit between the switch and the solenoid closes and waits for the next signal to be input. Rather than closing after receiving the signal, the circuit is closed before a certain amount of balls are supplied. It is important to do so.

Then, a weak current that cannot activate the solenoid is passed through this series circuit, and by forming a closed circuit in the series circuit, a signal different from the above is taken out, and this signal is followed by For example, it is possible to input the fact that the computer is ready to receive a signal for replenishment into a computer that controls replenishment, and set the timing for outputting the replenishment signal.

As explained above, in the ball replenishment system according to the present invention, the quantitative replenishment device for replenishing a fixed unit amount is placed facing the ball supply pipe of the pachinko machine, so one replenishment signal can only supply a fixed unit amount of balls. Pachinko machines are replenished, but the information is calculated by a computer according to the situation of the peak and entry of each pachinko machine, the amount of replenishment at one time is calculated, and the number of replenishment signals is set. By simply applying the supplied replenishment signal to the input side of a series circuit consisting of a switch and a solenoid, each pachinko machine in the game parlor can be replenished in a predetermined amount according to the desired number of times, making it possible to adjust the replenishment amount for each pachinko machine. It becomes.

In particular, the method of the present invention closes the series circuit between the switch and the solenoid before the end of replenishing a fixed amount of balls, and waits for the next replenishment. If the input is made at the correct timing, the desired amount of balls will be supplied to each pachinko machine.

Moreover, automatic operation or manual operation can be used for switching as required.

Moreover, according to the method of the present invention, the structure is extremely simple, so it is easy to install, and in an amusement hall that accommodates a large number of pachinko machines, it can be used with peace of mind, reducing the trouble of breakdowns and repairs. This is inexpensive and has the excellent effect of being able to adjust and supply desired balls to each pachinko machine.
