Description

[Detailed Description of the Invention] The present invention provides a plurality of passageways through which pachinko balls flow down in a line, a part of each sprocket is exposed inside each passageway, and the rotation of each of these sprockets is This invention relates to a device for passing a fixed number of pachinko balls, in which regulating rods are arranged side by side and the regulating rods are tilted all at once by the drive of an electromagnetic solenoid to allow a fixed number of pachinko balls to flow down.

As is well known, the device for passing a fixed number of pachinko balls is
It is used as an internal mechanism of a ball rental machine in a pachinko game parlor, or as a mechanism for supplying prize balls to each pachinko machine.

Conventional fixed number passing devices include those that store a fixed number of pachinko balls in a tilting gutter and tilt the gutter to pass a fixed number of balls, and those that pass pachinko balls into a semicircular notch in a sprocket. Some pachinko balls are supplied one at a time and a fixed number of pachinko balls are passed through by controlling the rotation of this sprocket. However, in fixed quantity passing devices that use a tilting gutter, after the pachinko balls in the gutter have flown down, they must be replenished with the next ball to flow down, so one cycle from the start of falling balls to the completion of ball replenishment takes a long time. Therefore, it is difficult to repeat a large number of ball passages in a short period of time. For this reason, if such a device is used as the internal mechanism of a ball rental machine, the amount of balls rented per unit time may be insufficient, the center may become crowded, or it may take a long time to rent out a large number of balls to one player. and cause discomfort.

In addition, most of the conventional quantitative passing devices that use sprockets only rotate one sprocket, which makes it impossible to obtain a sufficient ball passing speed. Although the time required for the ball to pass can be shortened, the sprocket often rotates without a pachinko ball entering the notch, and even in such cases, the next ball is allowed to pass. Therefore, it is difficult to keep the number of balls passing constant.

The present invention has been proposed in view of the above, and includes a plurality of passageways through which pachinko balls flow down in a line, and a part of the sprocket is exposed inside each passageway, so that each sprocket can be separately operated. Each sprocket is supported by a spindle in a rotatable state, and each sprocket is connected to a rotation regulating plate having a locking recess on the outer periphery, and each sprocket has a locking claw piece at the tip, and each of the sprockets is a regulating rod that can be rotated separately. A plurality of them are lined up to form a regulating rod group, each of the locking pawls is biased against the outer periphery of the rotation regulating plate, and the actuating member connected to the electromagnetic solenoid is placed facing the regulating rod group. Provides a fixed number passing device for pachinko balls that can reliably pass a fixed number of pachinko balls in an extremely short time by bringing a detection plate into contact with a regulating rod group and electrically connecting an electromagnetic solenoid and a switch. This is what I am trying to do.

Hereinafter, the present invention will be explained based on drawings of embodiments.

The fixed number passing device is equipped with five vertical passing gutter 1 in which pachinko balls flow down in a line,
A vertical groove 2 of the same height is formed on the side surface of each passageway 1, and a part of the sprocket 3 is exposed to the inside of the passageway 1 from the vertical groove 2.

The sprocket 3 has ten semicircular notches 4 on its outer periphery into which one pachinko ball can be inserted, and each is supported by a support shaft 5 in a state in which they can rotate independently.
Also, there is a sprocket 3 on one side of the sprocket 3.
A rotation regulating plate 6 having a diameter smaller than that of the rotation regulating plate 6 is concentrically connected, and locking recesses 7, 7 are formed on the outer periphery of the rotation regulating plate 6 at opposing positions with the support shaft 5 as the center. A rotating plate 8 is rotatably attached to the side surface of the rotation regulating plate 6, and the rotating plate 8 is attached to the cover pieces 10, 10 by a spring member 9.
is biased so that it always covers each of the locking recesses 7, 7.

Further, a shaft 11 is provided at the rear of the sprocket 3, and five regulating rods 12 are attached to the shaft 11 so that they can each rotate independently to form a regulating rod group 13, and are attached to the shaft 11. The locking claw pieces 16 bent and formed on the tip claw portions 15 of each regulating rod 12 are pressed against the outer circumferential surface of the rotation regulating plate 6 by the biasing of the springs 14 .

A notch 17 is formed in the rotary plate 8 so as to be located on one side of the lid piece 10, and when the notch 17 coincides with the locking recess 7, the locking claw piece 16 is inserted into the recess 7. When inserted, the rotation of the rotation regulating plate 6 is stopped, and the rotation of the sprocket 3 is stopped.

An upward hook 18 is formed at the rear end of each regulating rod 12, and an actuating member 20 is connected to an electromagnetic solenoid 19.
All of the five hook pieces 18 are inserted into the horizontally elongated holes 21. Then, the tips of the detection plates 22 are placed on the ends of the five hooks 18 protruding from the horizontally elongated holes 21 of the actuating member 20, and the base ends of the detection plates 22 are pivotally attached to the shafts 23. Switch 2 installed above
The four actuating pieces 24' are made to face the upper surface of the detection plate 22.

In such a configuration, when the electromagnetic solenoid 19 is demagnetized, as shown in FIG.
... are lowered in unison, and the locking claw piece 16 at the tip of each regulating rod 12 fits into the recess 7 from the notch 17 to prevent each sprocket 3 from rotating. Therefore, the pachinko balls in the passage gutter 1 are caught in the notch 4 of the sprocket 3 and do not flow down.

In this state, the tip of the detection plate 22 is lowered by its own weight, so the detection plate 22 is in a specific state, and the switch 24 transmits a ball passage enable signal to the electrical control device. The electric control device instantaneously energizes the electromagnetic solenoid 19 upon receiving the ball passage enable signal from the switch 24 and a signal from, for example, a coin detector.

When the electromagnetic solenoid 19 is energized, the actuating member 20
rises, the lower edge of the horizontally elongated hole 21 raises all the hooks 18 at the same time, and all the regulating rods 12
…Turn all at once. When the regulating rod 12 rotates,
As shown in FIG. 3, as the hook piece 18 moves up the tip of the detection plate 22, the detection plate 22 moves to the operating piece 24'.
The switch 24 stops the pass permission signal.

Also, when the regulating rod 12 rotates, the locking claw piece 1 at the tip
6 is removed from the notch 17 and the recess 7, the rotating plate 8 is rotated by the bias of the spring member 9, and the lid piece 10 covers the recess 7, as shown in FIG. Therefore, even if the electromagnetic solenoid 19 is demagnetized, the locking claw piece 16 rests on the surface of the lid piece 10. When the locking claw pieces 16 are removed from the recesses 7, each sprocket 3 becomes free to rotate, so the pachinko balls in the passage gutter 1 are sequentially received by the notches 4, causing the sprockets 3 to rotate under the downward force. while flowing down.

Then, each sprocket 3 rotates approximately half a turn and rotates 5 times each.
When pachinko balls pass through, the locking claw piece 16 hooks on the edge of the lid piece 10 on the opposite side to stop the rotation of the rotating plate 8, and then fits into the locking recess 7 on the opposite side. to prevent the sprocket 3 from rotating. When each locking claw piece 16 fits into each recess 7 in this way,
All the sprockets 3 are prevented from rotating, and the pachinko balls in each passageway 1 do not flow down.

As described above, in this embodiment, when the electromagnetic solenoid 19 is energized once, each sprocket 3 rotates half a turn to reach 5 sprockets, that is, a total of 25 sprockets in the entire passing device.
Pachinko balls can pass through it.

When the pachinko ball has passed once and the locking claw pieces 16 of each regulating rod 12 fit into the respective recesses 7 and return to the initial state, all the hook pieces 18... descend to the same position. Since the height is aligned, the tip of the detection plate 22 descends and returns to the specific state of being stationary, and the switch 24
again transmits the ball passability signal to the electrical control device. Therefore, when the electric control device re-energizes the electromagnetic solenoid 19, the sprocket 3 can rotate and immediately pass 25 pachinko balls.

However, if there is a shortage of pachinko balls in the passage gutter 1 on the upstream side of the sprocket 3, or if the balls are clogged, even if the sprocket 3 is able to rotate freely due to the excitation of the electromagnetic solenoid 19, there will be no pachinko balls in the notch 4. Since it does not enter, sprocket 3 will not turn half a turn. Therefore, the locking claw piece 16 that has come off from the recess 7 cannot be inserted into the recess 7 again. Therefore, as shown in FIG. 4, even when the other regulating rods 12 return to their initial states, the regulating rods 12 of the passage gutter 1 keep their hooks 18' raised and cannot return to their initial states. I can't. Therefore, the tip of the detection plate 22 is supported by the hook 18' of the regulating rod 12' and is prevented from restoring, and the ball passage enable signal from the switch 24 continues to be stopped. Therefore, if a problem such as ball clogging occurs and the number of balls that have passed is insufficient, the operation can be stopped by the passing operation, and the occurrence of the trouble can be notified.

In this embodiment, in order to prevent multiple rotations of the sprocket 3, stoppers 25, 25 are provided to protrude above one side of the recess 7.
The distance between the lower surface of the rotation regulating plate 5 and the circumferential surface of the rotation regulating plate 6 is set to such an extent that the locking claw piece 16 can pass through. Therefore, when the sprocket 3 rotates due to the excitation of the electromagnetic solenoid 19 and the pachinko ball flows down inside the passage gutter 1,
The electromagnetic solenoid 19 immediately demagnetizes the locking claw piece 1.
6 slides on the circumferential surface of the rotation regulating plate 6, the locking pawl piece 16 passes through the gap between the circumferential surface of the regulating plate 6 and the stopper 25, fits into the recess 7, and stops the rotation of the sprocket 3. can do.

However, if magnetism remains in the electromagnetic solenoid 19 or if the regulating rod 12 does not return and rotate for some reason, the locking claw piece 16 will collide with the stopper 25 when the sprocket 3 rotates half a turn, so the sprocket 3 rotation can be stopped. Therefore, excessive rotation of the sprocket 3 can be prevented, and more than a fixed number of pachinko balls will not be allowed to pass through.

Further, as shown in FIG. 5, it is desirable to provide a swingable magatama-shaped cam 26 on the underside of each sprocket 3 so that one pachinko ball does not cause the sprocket 3 to rotate excessively. This cam 26 swings repeatedly while being played by the notch 4 of the rotating sprocket 3, and alternately moves its tip and rear end to the notch 4.
By fitting in the sprocket 3, it is possible to prevent the sprocket 3 from rotating excessively.

Note that the electrical control device can be appropriately designed according to the intended use of the fixed quantity passing device. 6th
The embodiment of the electrical control device 27 shown in the figure is used in a ball lending machine that can use 100 yen coins and 500 yen coins, and the signal from the 100 yen coin detector 28 is sent to the first storage circuit 29. 500 yen coin detector 3
The signal from 0 is stored in the second storage circuit 31. When the AND gate 32 is opened by the ball passage enable signal from the switch 24 and the signals from the first and second memory circuits 29 and 31, the electromagnetic solenoid 19 is excited by a pulse from the pulse generation circuit 33, A certain number of pachinko balls are passed as described above. For example, when two 100 coins are detected, the electromagnetic solenoid 19 is energized once to allow 25 pachinko balls to pass, and then the AND gate 32 is immediately opened and the electromagnetic solenoid 19 is energized again to pass a total of 50 pachinko balls. pass the pachinko ball. and 200
When 50 pachinko balls corresponding to yen pass, a reset signal from the comparator circuit 34 causes the first memory circuit 29 to pass through.
Reset the memory and end the ball rental.

The actuating member 20 is not limited to the above embodiment, and may have any configuration as long as it can face the group of regulating rods and rotate all the regulating rods at once. For example, another embodiment of the actuating member 20 shown in FIG. 7 is a rotatable plate material whose base end is pivoted and whose distal end faces midway through all the regulating rods 12 from above, and whose top surface Iron core 1 of electromagnetic solenoid 19
9' is in contact with the lower end. Therefore, when the electromagnetic solenoid 19 is energized, the iron core 19' tilts the actuating member 20, so that the tip of the actuating member 20
...can be rotated all at once.

Further, the detection plate 22 is not limited to the above embodiment, and is in contact with the regulating rod group 13, and each of the locking claw pieces 1
Any configuration may be used as long as the switch 24 can be operated when the regulating rods 12 are fitted into the respective recesses 7 and the inclinations of all the regulating rods 12 are aligned. For example, in another embodiment of the detection plate 22 shown in FIG. 7, the detection plate 22 is pivoted in the middle, and the tip abuts on the middle of all the regulating rods 12 from below under the force of a spring 35, and the switch 24 is mounted on the bottom surface. This is what I brought to you. Therefore, when all the regulating rods 12 are in their initial state, the detection plate 22 raises its tip end as shown by the solid line in FIG. However, if the locking claw pieces 16 of all the regulating rods 12 come off the recessed part 7, or if any one of the locking claw pieces 16 comes out of the recessed part 7.
If the ball does not fit into the ball, the tip part is lowered and stopped as shown by the chain line in FIG. 7, and the switch 24 does not issue a signal allowing the ball to pass.

In this example, five sprockets 3 are arranged in parallel, and each sprocket 3 is rotated half a turn at the same time, so that a total of 25 pachinko balls can pass, but the number of passing balls is 25 each time. However, the number of sprockets 3 may be changed, the number of notches 4 may be changed, or the number of sprockets 3 may be changed.
Adjustment can be made by interposing a speed reduction mechanism such as a gear between the rotation regulating plate 6 and the rotation regulating plate 6.

As explained above, according to the present invention, the passing gutter through which the pachinko balls flow down in a row is arranged in parallel, and the sprocket is facing each passing gutter, so that all the sprockets can be rotated at the same time. You can pass a certain number of pachinko balls in a certain amount of time. Therefore, when the present invention is used as an internal mechanism of a ball rental machine, a large number of pachinko balls can be rented out in a short time, and even if there are many users, there is no need to keep them waiting.

In addition, in the present invention, the detection plate that operates the switch is brought into contact with the regulating rod group, and the switch and the electromagnetic solenoid are electrically connected, so that only when the appropriate number of pachinko balls has passed, the next Make passage possible. Therefore, if there is even one sprocket that does not rotate due to a ball being clogged or missing in any of the passageways, the regulating rod biased around the outer circumference of the rotation regulating plate of that sprocket will be detected. The tip of the plate is raised, and the detection plate acts on the actuating piece to stop the passing signal of the switch. If the predetermined number of balls do not pass, the passing device stops operating, so the number of pachinko balls that have passed is determined. Troubles caused by insufficient errors can be prevented, and the user will not experience any disadvantage or discomfort. In addition, since there is only one detection plate for operating the switch for generating the ball passage enable signal, the configuration can be simplified and the device can be made smaller.
