Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic pachinko ball lending machine in the form of a vending machine that automatically lends out pachinko balls, and in particular, inserts coins only by purely mechanical means without using any electrical means. This invention relates to an automatic pachinko ball lending machine configured to automatically dispense a predetermined number of pachinko balls corresponding to an amount of money.

Recently, pachinko balls, which are lent out in predetermined quantities at pachinko parlors, are being lent out using pachinko ball rental machines in the form of vending machines, as pachinko parlors are saving labor.

As the supply and collection of pachinko balls are all becoming centrally controlled, pachinko ball rental machines are also incorporated into a series of pachinko ball supply systems, and are installed between pachinko machines when they are installed, saving space and Pachinko balls can be rented at nearby locations.

Even with this type of pachinko ball rental machine, the first condition is to accurately dispense the amount of balls according to the coins inserted, and at the same time, it must always operate accurately and without any breakdowns. required.

However, in the conventional pachinko ball rental machines mentioned above, the operation of dispensing a predetermined number of pachinko balls after the sorting of the inserted coins is completed is done using electrical means such as electromagnets. Electrical work had to be carried out.

Therefore, not only does the manufacturing cost of pachinko ball rental machines increase, the installation work of the pachinko machine depends on the construction period of the electrical wiring work, and furthermore, in the event of an electrical failure, specialist engineers must be involved. First, there were various problems such as the fact that it was not easy to repair.

On the other hand, if high-value coins (for example, 500 yen) are put into circulation in addition to the current 100 yen coin,
In addition to the conventional 100 yen coin, there is a need for a ball lending machine that can lend balls using 500 yen coins.

However, when using an automatic ball dispensing machine that dispenses pachinko balls only by mechanical means as described above, the locking mechanism that stops the dispensing of pachinko balls is removed by a falling blade of the coin, and the pachinko balls flow out. Due to the structure involved, for example, a star wheel-shaped ball counter plate that engages with pachinko balls supplied into the ball path and is rotated by the pachinko balls to count them, and teeth that engage with the pachinko balls are used. If the number is multiplied by the amount of money of the number of balls in a 100 yen coin (5 times in the case of a 500 yen coin), the locking mechanism needs to be stopped in one rotation, so the ratio of the number of teeth of the gear leading to this point is significantly large. This results in an extremely large load being applied, and it is extremely difficult to remove it with a falling coin blade due to the structure, which may cause malfunctions or
This is accompanied by problems such as causing malfunctions.

In view of this, the present invention configures the ball discharging mechanism of an automatic pachinko ball lending machine by purely mechanical means, allows it to start operating as soon as it is installed in a store, and provides the ball lending machine itself at a low cost. At the same time, it simplifies the installation work at the store and greatly shortens the installation work, while ensuring reliable dispensing with extremely small force without placing a large load on the locking mechanism even when dispensing high-value coins. The purpose of this invention is to provide an automatic ball dispensing machine for pachinko that can be operated.

The present invention will be described below with reference to embodiments shown in the drawings.

The example shown in the figure assumes a 500 yen coin as a high-value coin, and by repeating this 5 times based on the pachinko ball throwing operation equivalent to 100 yen by hardening the 500 yen coin,
This example shows a case in which pachinko balls worth 0.00 yen are thrown out.

In the description of the embodiment, for convenience, it will be represented by C, which is a 500 yen coin, and C501 in the order of precedence.

It is represented by C502......

The overall structure of the automatic pachinko ball lending machine is as shown partially in FIG. , a coin sorting machine 4 which determines the suitability and type of coin C inserted through this coin passage 3, accepts the coin if it is a proper coin, and returns it if it is a fraudulent coin; It consists of a pachinko ball dispensing device 5 for dispensing a predetermined number of pachinko balls using coins.

The ball passage 2 is converted from a vertical passage 2a located at the rear of the machine body 1 and communicating with the ball supply system to the front side via an oblique passage 2b, and is installed vertically along the front surface of the machine body 1.

The gear ratio of the gears 20, 21, and 25 is such that the ball counter plate 16 rotates by the number of balls to be paid equivalent to 100 yen (in the example, 10 per rotation) during one rotation of the gear 25. It is set.

On one side of the pachinko ball dispensing device 5, as shown in FIGS. 3 and 4, there is a coin passage 3 through which 500 yen coins C, which are sorted by the sorter 4 and determined to be correct, are dropped.
1 is provided.

A coin abutting portion 33a at one end of a coin sensing lever 33, whose intermediate portion is pivotably supported by a shaft 32, protrudes into the coin passage 31.
A weight eight 34 is attached to the other end of 3.

The coin sensing lever 33 is made of a lightweight material such as synthetic resin or light metal, and the coin C is connected to the coin abutting portion 33a.
It is designed to respond sensitively in the event of a falling collision.

The ball counter stopper 35 has an intermediate portion pivotably supported by a shaft 36, and a pawl 37 at one end of the ball counter stopper 35 is arranged to be able to engage with the stepped portion 27 of the ball counter stop plate 26.

A weight 23 is attached to the rear end, and a claw 37 is always attached to the rear end.
is biased in the direction of engagement with the stepped portion 27.

The coin stopper 38 is mounted on a shaft 39 at a position spaced apart above the coin contact portion 33a of the coin sensing lever 33.
The side surface of the pivoted part facing the coin passage 31 is formed into a coin fitting part 40 recessed in an arc shape into which a part of the coin C can be engaged, and the hanging part 38a is connected to the coin passage 3.
1, and when hanging down, the upper end 40' of the coin fitting part 40 is placed in almost the same plane as the inner surface of the coin passage 31, and the lower end 40 is necessarily It is configured to enter the coin passage 31 and prevent the coin C from falling.

The coin stopper 38 is provided with locking protrusions 41 projecting from shoulder portions above the shaft 39, respectively.

A coin stopper lock lever 42 is pivotally supported by a shaft 43, and the coin stopper 38 is attached to this lock lever 42.
A protrusion 44 that engages and disengages from the protrusion 41 is formed.

Coin stopper holding lever 45 and lock release lever 46
The upper end of the holding lever 45 faces the back of the hanging portion 38a of the coin stopper 38, and the lower end is in contact with the cam 22 on the shaft 19.

Further, the tip of the release lever 46 faces the rear surface of the hanging portion of the lock lever 42, and the lower end is brought into contact with a cam of a counting mechanism to be described later.

The engagement positional relationship, operation timing, etc. of each of the above-mentioned members will be explained in detail later when explaining the operation.

The dispensing mechanism that dispenses 500 yen worth of pachinko balls with a 500 yen coin operates the mechanism that dispenses 100 yen worth of pachinko balls five times in one operation, and there is a counter that counts the number of operations. Equipped with a mechanism.

This counting mechanism includes a mechanism that is locked by a coin sensing lever 33 when the ball counter stop plate 26 has repeatedly thrown out pachinko balls worth 100 yen five times.

That is, it is rotatably attached to the machine frame 15 by a shaft 48, and five pins 49, 49, . The notch 50 includes an arm portion 520 extending along the circumferential surface of the rotary plate 510 of the coin sensing lever 33 and a protrusion 5 protruding from the surface on the rotary plate 51 side.
3 can be freely engaged, and when engaged, the rotary plate 51 is restrained from rotating.

Further, a positioning lever 54 for stopping the rotary plate 51 at a fixed position is pivotally attached to the coin sensing lever 33 and biased by a spring toward the bin 49 side.

On the other hand, the operating lever 55 that rotates the rotary plate 51 is
The intermediate portion thereof is pivoted by the shaft 47, forming a downward U-shape, and is biased counterclockwise in the figure by a spring 56.

This operating lever 55 has the pins 49, 49...
A feed pawl 57 that engages with the bin 49 to feed it clockwise one pitch at a time and rotates the rotary plate 51 intermittently is pivoted and biased by a spring in a direction that engages with the bin 49. ing.

The other end of the operating lever 55 is disposed at a position where it is pushed by a protrusion of a cam 58 on the shaft 19, and when the cam 58 rotates clockwise in the figure, the feed claw 57 moves the bottle 49 one pitch. It is designed to send minutes.

In addition, the lower end 55 on the left side in the drawing of the operating lever 550
b is opposed to the upper surface 35a of the tip end of the ball counter stopper 35, and the left side portion of the operating lever 55 (in the illustrated example, the pivot of the feed pawl 57) is attached to the upper end of the arm portion 52 extending above the coin sensing lever 33. It is now possible to stop the descent.

Therefore, when the coin sensing lever 33 swings downward and its arm portion 52 comes off, the operating lever 55 rotates counterclockwise due to the action of the spring 56, causing the ball counter stopper 35 to swing downward. , the claw 37 is removed from the ball counter stop plate 260 role part 27.

In the figure, 60 is a governor for the ball counter plate 16, and 61 is an outlet for discharging fraudulent coins.

Next, the operation of the above embodiment will be explained.

When pachinko balls are being supplied to the automatic pachinko ball rental machine, the pachinko balls fill the ball passages 2a, 2b and 2c, and reach the ball counter plate 16.

At this time, the ball dispensing device 5 is configured such that the pawl 37 of the ball counter stopper 33 is connected to the ball counter stop plate 26 as shown in the third figure.
The protrusion 53 of the coin sensing lever 33 engages with the notch 50 of the rotary plate 51, and the ball counter stop plate 26 is restrained, so that the coin sensing lever 33 is integrated with the ball counter stop plate 26. The gear 25 is placed in a locked state and the ball counter plate 16 is restrained from rotating.

Therefore, even if the load of the pachinko balls is applied to the teeth of the ball counter plate 16, the ball counter plate 16 remains stationary without rotating.

At the same time, the swinging rod 7 is moved by the pachinko balls in the ball passage 2c.
Since the ball detecting part 12 is pushed and pushed out of the passage 2c, the shielding part 10 at the opposite end is removed from the coin slot 9, and at the same time, a display 13 indicating "Rental" appears in the window hole 14, Indicates that it is available for use.

In this state, when a 500 yen coin C is inserted into the coin slot 9, it passes through the coin passage 3 and enters the coin sorter 4, where it is determined whether it is a proper coin or not. If the coin is proper, it is fed into the coin passage 30, and if it is a fraudulent coin, it is returned from the outlet 61.

Now there are multiple coins C501, C502...
. . are turned on at the same time will be explained with reference to FIGS. 5 and 6.

When the coin C501 falls down the coin passage 31 as shown in the fifth figure, the coin C501 temporarily enters the coin fitting part 40 of the coin stopper 38, but the coin C
Since the lower end 40'' of the fitting portion 40 is pushed by the weight of C501, the coin stopper 38 rotates counterclockwise around the shaft 39, allowing the coin C501 to pass.

This rotation of the coin stopper 38 causes the lock lever 4 to
Since the protrusion 44 of the coin stopper 38 falls off from the protrusion 41, the protrusion 44 on the upper part of the lock lever 42 falls down and comes into contact with the protrusion 41 of the coin stopper 38. 6, it is stopped against the upper end 40' of the coin fitting part 40 of the coin stopper 38.

The coin C501 that has passed through the coin fitting part 40 of the coin stopper 38 is accelerated and collides with the coin abutting part 33a of the coin sensing lever 33, which is positioned with a required height with respect to the fitting part 40. The impact causes the coin sensing lever 33 to swing counterclockwise around the shaft 32 (as shown in the sixth figure).

In this case, the coin sensing lever 33 swings slowly and greatly due to the inertia of the initial movement of the weight 34.

The coin C501 that has swung through the coin sensing lever 33 falls onto the back side of the machine body 1 and is collected by a conveyor or the like (not shown).

When the coin sensing lever 33 swings counterclockwise as described above, the protrusion 53 of the arm 52 disengages from the notch 50 of the rotary plate 51, and the upper end of the arm disengages from the axis of the feed pawl 57, causing it to rotate five times. The counting mechanism is unlocked.

When the 5-turn counting mechanism is unlocked as described above, the operating lever 55 is rotated counterclockwise around the shaft 47 by the spring 56, so that the lower left tip 55b in the figure touches the upper surface 35a of the ball counter stopper 35. This causes the pawl 37 to touch the stepped portion 27 of the ball counter stop plate 26.
come off from

The claw 37 is the ball counter stop plate 260 step part 2
7, the ball counter stopper V-) 26 momentarily rotates counterclockwise by the action of the spring 290 to the extent that it hits the stopper, and as shown in FIG. 8B, the large diameter portion 28
The ball counter stopper 35 enters a position where it can come into contact with the tip of the claw 37, and even if the ball counter stopper 35 attempts to return to its original position under the action of the weight 230, it cannot return.

Due to the above action, the gear 25 on the shaft 30 including the ball counter stop plate 26, which has been restrained by the ball counter stopper 35, becomes able to rotate.

Therefore, the ball counter plate 16, which had stopped receiving the pachinko balls and remained stationary due to the non-rotation restraint of the gear 25, begins to rotate due to the weight of the pachinko balls, and the stepped portion 27 of the ball counter stop plate 260 moves as shown in the fifth figure. The ball is rotated until it hits the pawl 37 of the ball counter stopper 35 again.

At the same time, the side surface of the right hanging part of the operating lever 55 is pushed to the left in the figure by the cam 58, so the operating lever 55 rotates clockwise, and the feed pawl 57 becomes one as shown in FIG. Hook the pin 49 and pull up the rotating plate 5.

However, at the fifth rotation, the holding lever 45 is swung counterclockwise by the cam 22, and the release lever 46 is rotated by the rotating plate 5.
Since the cam 51a on the shaft 48 of No. 1 swings counterclockwise and lifts the lock lever 42, the protrusion 41 of the coin stopper 38 also comes off the protrusion 44 of the lock lever 42, and due to its own weight and the weight of the coin C502. The upper end 40' of the fitting part 40 of the coin stopper 38 is
moves clockwise, and the falling coin C502 pushes down the coin stopper 38 until it hits the holding lever 45 (FIG. 7).

When the five-rotation counting mechanism completes five operations, the holding lever 45 returns to its original position, and the coin stopper 38 is pushed down and rotated by the weight of the coin C502, returning to the state shown in FIG. 6.

When the rotating plate 51 completes one rotation, the notch 50 comes to the position of the protrusion 53 of the coin sensing lever 33 and the upper end of the arm 52 of the coin sensing lever 33 is placed under the pivot of the feed pawl 57 of the operating lever 55. The rotary plate 51 is restrained by entering and engaging with the rotary plate 51.

The rotational position of the rotary plate 510 is determined by a positioning lever 54.

Although the holding lever 45 is moved every rotation until the rotary plate 51 of the five-turn counting mechanism rotates five times by the coin C501, there is no problem in holding subsequent coins.

As explained above, the automatic pachinko ball dispensing machine according to the present invention does not use any electrical means for discharging pachinko balls based on the insertion of coins, but only by mechanical means. The ball rental machine can be installed at the same time as the pachinko machine without requiring any accessories, which significantly shortens the installation period, and it is extremely inexpensive as it does not use any electrical parts such as solenoids or magnets. Furthermore, there are no electrical failures, and maintenance is easy.

The energy for throwing out the pachinko balls is generated by using the impact force caused by the falling acceleration of the inserted coin, and by using the weight of the pachinko balls themselves to make them count and throw out, so there is no need for any other power source. The falling blade is used as a force to release the stop of the counting mechanism, so even small coins can be operated reliably.

In particular, the ball counter stop plate portion that locks the ejection of pachinko balls by the ball counter stopper can have a reduction ratio of one-fifth of that of the ball counter plate, to which the weight of the pachinko balls is applied, in the illustrated embodiment, for example. At σ, the load applied to this part is extremely small, and therefore the force required to release this lock part is extremely small, making it possible to start a reliable dispensing operation without the need for a large mechanism. It has various effects such as being able to significantly downsize the structure of the iron part.

In the illustrated embodiment, the case where a 500 yen coin is used as the high-value coin is explained, but the amount is not limited to this, and the case where the throwing operation of pachinko balls equivalent to 100 yen is used as the standard. However, this can also be selected as appropriate.

Further, the structure and shape of the constituent members of each part need not be limited to those shown in the drawings, and design changes may be made arbitrarily without departing from the technical idea of the present invention.
