Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pachinko ball counting machine.

As is known, a predetermined number of prize balls are supplied and stored in a pachinko machine, and a counting machine is used to count the number of prize balls and stop the supply when a predetermined number is reached. .

Conventionally used counting machines have a sprocket-like ratchet wheel with a constant number of recesses on its circumference facing the pachinko ball supply gutter, and each ball receives one ball in each recess and rotates. The number of feeds is counted from this rotational speed, and when a predetermined number of passes have been made, the rotation of the ratchet wheel is stopped to stop the feed.

Mechanical or electrical measures are taken to count the number of rotations of the ratchet wheel and stop the rotation, but mechanically, the stopper is placed facing the ratchet wheel and the locking pawl of the stopper is engaged with the recess provided in the ratchet wheel. A common method is to stop them at the same time.

The latching stop by this stopper is to stop the rotating ratchet wheel, but normally it is to stop the passage of the ball and stop the supply. The stopper is operated to disengage the locking pawl and allow the ratchet wheel to rotate.

This disengagement is performed by energizing the solenoid, but for example, when replenishing all machines with prize balls at the start of a pachinko parlor, it is necessary to energize each solenoid, which temporarily Since a concentrated and large current is required, improvements are currently being made to release the engagement of the stopper in as short a time as possible.

However, if the excitation time is set to a short time, there is a problem in that the stopper that has disengaged from the engagement recess of the ratchet wheel will engage the same recess again, making the release ineffective and replenishment impossible.It is desirable to solve this problem. It was rare.

This invention was researched and developed in view of this.
When the relative position of the ratchet wheel and the rotation regulating piece that restricts over-rotation of the ratchet wheel that rotates when supplying pachinko balls is identified, and the engagement of the stopper is disengaged from the engagement recess of the ratchet wheel by operating a solenoid. , the ratchet wheel is automatically rotated slightly and the position of the engagement recess is moved to prevent the removed stopper from returning to the same engagement recess and engaging again, and thereby the solenoid To provide a counting machine which can shorten the energizing time to the maximum, suppress large current consumption, prevent supply failures, and ensure smooth operation.

Hereinafter, this invention will be explained with reference to the illustrated embodiments, and its features will be explained in detail.

Figure 1 is a partially cutaway front view, Figure 2 is a plan view, and Figure 3 is a partially cutaway exploded perspective view of the main parts. 2 is a mounting piece provided to fix the board; 3 is a drainage gutter through which the pachinko balls are aligned in a line; and 4 is a slit 3a provided in the drainage gutter, through which a claw connected to the circumferential surface is inserted, and the gutter is A ratchet wheel is rotated while receiving and sending pachinko balls flowing down the inside one by one into a recess 4a, 5 is a rotation regulating piece that prevents the ratchet wheel from over-rotating due to inertia, and 6 is a rotation regulating piece that decelerates the rotation of the ratchet wheel. Two large and small gears 6a, 6 transmit information to the counting gear 7 while
8 is a stopper member that stops the rotation of ratchet wheel 4 and counting gear 7 when a predetermined number of pachinko balls have passed; 9 is a solenoid that releases the restraint state of this stopper member.

The ratchet wheel 4 and the counting gear 7 are rotatably supported on a support shaft 10 embedded in the board, and the reduction gear 6 is supported on the support shaft 10.
0, the large gear 6a is engaged with the small gear 12 of the ratchet wheel 4, and the other small gear 6b is engaged with the reduction gear 7. A ratchet wheel 4 rotated by pachinko balls flowing down
The rotation is transmitted to the counting gear 7 while being decelerated.

In this embodiment, ten recesses 4a are arranged in succession on the circumferential surface of the ratchet wheel, and one rotation counts ten balls, and an additional 40 rotations counts the counting gear 7 by one.
The number of teeth is the same as that of the reduction gear 6 so that the gear rotates quickly.

Disks 13 and 14 having approximately the same diameter are provided on opposing surfaces of the ratchet wheel 4 and the counting gear 7, and one engagement recess 15 and 16 is provided on each peripheral surface by a notch. is provided, and the stopper member 8
By locking the locking pawl 8a, the rotation is stopped, and by stopping the ratchet wheel, the flow of the balls in the downflow gutter is stopped.

The stopper member 8 is supported by a shaft 17 so as to be able to swing freely, and the stopper member 8 is biased by a spring 18 to lock the stopper member 8 at the tip of the stopper member 8 to the disc 1.
3 and 14 in pressing and sliding contact with the concave portions 1 of both disks.
5 and 16 meet at the end of the locking claw 8a, the locking claw 8a engages with the locking claw 8a to stop rotation.

On the other hand, the solenoid 9 is provided to release the rotation restraint state by the stopper member 8, and when it is in a demagnetized state, it extends the iron core 19 and releases the flange-shaped hook 2.
The arm 21 at the rear end of the stopper member that engages with the lock is lifted up, and when the restraint is released, electricity is applied to pull in the iron core 19 and the stopper member is swung about the shaft 17 to release the locking pawl 8a from the recesses 15 and 16. The rotation of the ratchet wheel 4 and the counting gear 7 is released.

By the way, the rotation regulating piece 5 is for preventing the ratchet wheel 4 from over-rotating due to ball pressure and causing incorrect counting when the stopper member is released.
The engaging pawls 5a and 5b provided at the front and rear ends of the shaft 22, which are installed directly above the shaft 22, are slidably fitted into the recesses 4a of the ratchet wheel.
The rocking motion causes one recess to rotate.

As shown in the figure, a weight 23 is buried in the rear end so that the engaging pawl 5b at the rear end always slides into the recess 4a, and the rotation of the ratchet wheel causes the engagement claw 5b to slide into the recess 4a. When the engaging pawl 5b rises along the line and moves to the next recess, the engaging pawl 5a at the tip slides into the recess. Furthermore, when the locking pawl 8a of the stopper member 8 engages in the recess 15 of the disk 13 provided on the ratchet wheel 4 to restrain rotation, the engaging pawl 5b at the rear end moves its tip into the recess shown in FIG. 4a, and the weight of the weight 23 acts to slide on this slope, so that when the locking pawl 8a is disengaged from the engagement recess 15, it slides on the arc-shaped slope and engages. The pawl 5a is lowered, the ratchet wheel 4 rotates in the forward direction, and the concave portion 15 of the disk moves.

FIGS. 4 and 5 show this relationship. That is, the recesses 15 and 1 provided in the disks 13 and 14
6 are aligned and the locking pawl 8a of the stopper member 8 is engaged and rotation is restrained, that is, in the state shown in FIG. When 8a is removed, the locking pawl 5b of the rotation regulating piece 5 slides down the slope of the recess 4a under the weight of the weight 23, slightly rotating the ratchet wheel 4 to advance the position of the recess 15 and lock it. This prevents the claw 8a from re-engaging as shown in FIG. 5B.

This operation can be performed externally, for example by operating a switch provided in the control room of a pachinko parlor.
This is done by energizing the The ratchet wheel, which stops the flow of balls in the stopped state, rotates to supply balls, and also transmits rotation to the counting gear 7, which rotates once as described above, and the recess 1
When the locking pawl 8a of the stopper member 6 faces and the concave portion 15 of the ratchet wheel 4 faces, they are engaged, rotation is stopped, and supply is stopped.

The present invention is constructed as described above, and when the engagement recesses 15 and 16 of the ratchet wheel 4 and the counting gear 7 are aligned with the engagement toe of the stopper member 8, they engage to stop the pachinko ball from rotating. When the solenoid 9 is energized by a supply instruction, the engagement is released and the ratchet wheel is rotated. Through this rotation, a predetermined number of pieces are supplied. The supply can be completed by engaging the stopper member at the same time as the supply, and the stopper member 8
By simultaneously stopping the ratchet wheel and the counting gear, an accurate number of balls can be supplied. When the rotation regulation piece 5
Due to the push-out, the ratchet wheel 4 automatically rotates slightly and the engagement recess 15 facing the locking pawl 8a moves, thereby preventing engagement at the same position again.

Therefore, there is no need to hold the stopper member in the released state for a long time, as was the case with conventional counters of this type, and since the solenoid can release the restraint of the ratchet wheel by instantaneous energization, it can be used in large numbers with low power consumption. This is extremely convenient when it is necessary to temporarily energize a solenoid.

In addition, by supplying such a small amount of power for a short period of time, in other words, it is possible to release the restraint of the stopper member with a small force, the solenoid can be made smaller compared to conventional ones, and the counting machine itself can be made smaller. It has the advantage of being small and inexpensive to manufacture.
