Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin dispensing device capable of dispensing coins at high speed.

[Conventional technology]

Vending machines, money exchange machines, and game machines that use coin-shaped medals, such as slot machines, do not accept coins or medals (
A coin dispensing device for discharging coins (hereinafter collectively referred to as coins) to an ejection port is built-in.

'In conventional coin dispensing devices, a rotating disk driven by a motor is tilted at an angle of, for example, about 60 degrees with respect to the horizontal, in a bucket containing a large number of coins to be dispensed. It is placed in Coin locking portions are formed on a predetermined circumference of the surface of the rotating disk, maintaining a constant pitch according to the outer diameter of the coin, and protruding with a thickness equal to that of a coin branch. The lower side of this rotating disk faces the bottom of the bucket, and the upper side faces a coin passage connected to a coin outlet. When the rotating disk is rotated, the coins held in a ring shape on a predetermined circumference of the rotating disk by the rotating disk and the coin locking portion are sequentially sent upward through the coin passage. The coin passes through and is sent out from the coin outlet.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional coin dispensing device, the rotating disk is arranged at an angle, and the weight of the coins in the coin container is directly applied to the lower side of the rotating disk, giving a large load to the rotating disk. This is the result. Therefore, it is extremely difficult to increase the speed of driving the rotating disk, and even if you try to improve the coin dispensing efficiency, you can only increase the efficiency to about 4 to 5 coins/second. This is the reality.

The present invention was made in order to solve the drawbacks of the conventional coin dispensing device described above, and it enables the rotating disk for dispensing coins to be driven at high speed, thereby significantly improving the efficiency of dispensing coins. The purpose of the present invention is to provide a coin dispensing device that can dispense coins.

[Means for solving problems]

In order to achieve the above object, in the coin dispensing device of the present invention, a substantially horizontal rotating disk is provided below the bucket, thereby applying a centrifugal force to the coins supplied from the opening below the bucket. There is. The coin moved to the outside of the rotating disk by this centrifugal force is received by the guide plate and reaches the discharge port while being guided by the guide plate as the rotating disk rotates. A support that extends into the bucket through the opening of the bucket is erected on the rotating disk. A regulation plate is rotatably attached to this support, and receives the coins in the bucket above the opening to prevent the load from the large number of coins in the bucket from being directly applied to the rotating disk. .

An embodiment of the present invention will be described below with reference to the drawings.

〔Example〕

In FIG. 5, which shows the slot machine with the front door 1 open, the main body 2 to which the front door 1 is pivoted has a well-known reel device 3 including three reels with symbols arranged around the outer periphery. It is provided. When playing the game, the front door 1 is closed, but a part of the symbol arrangement on the reels can be viewed through an observation window 4 provided in the front door 1.

Coins inserted prior to the start of a slot machine game are sent to a coin sorter 6 from an exit 5 connected to a coin slot (not shown). The coin sorter 6 determines the authenticity of the inserted coin and sends the correct coin to the output roller.
The coins are fed into the bucket 12 of the coin dispensing device 10 via the gutter 8.

Incorrect coins should also be sent to exit 9. It is discharged into the tray 13 via the gutter 11.

When a prize is won as a result of playing the game, the coin dispensing device 10 is activated, and coins corresponding to the prize are sent out from the chute 14 and passed through the opening 15 formed in the gutter 11 into the receiving tray. It will be paid out on the 13th. To replenish coins to the coin dispensing device 10, open the cover 16 provided above the main body 2, and then open the tank 17.
If a large number of coins are placed in the bucket 12, they will be sent to the bucket 12 through the gutter 18. Bucket 12
An opening 19 is formed on one side of the ? When the game is repeated with the maquette 12 full,
Coins overflowing from the bucket 12 pass through the opening 19 and are collected in the auxiliary container 20.

In FIG. 1, FIG. 2, and FIG. 3 showing an example of the coin dispensing device 10, a rotating disk 24 driven by a motor 23 is provided on a base plate 22 that is attached almost horizontally to the main body 2 of the slot machine. It is being Also,
A generally cylindrical guide plate 25 is fixed to the substrate 22 so as to surround the outer peripheral edge of the rotating disk 24 .

As is clear from FIG. 3, a portion of the guide plate 25 is formed as a bent portion 25a that extends inside the rotating disk 24. As shown in FIG. A horizontally long slit 2 is provided at the lower edge of this bent portion 25a.
6 is formed. The height and width of this slit 26 are set so that only one horizontally oriented coin 30 can pass through.

Note that there may be a gap between the outer circumferential edge of the rotating disk 24 and the inner wall of the guide plate 25 as long as it is less than or equal to the radius of the coin 30.

A funnel-shaped bucket 12 with an opening 28 formed in the bottom surface is provided above the substrate 22. The coins accommodated in the bucket 12 pass through the opening 28 to the rotating disk 24.
be dropped upwards. As shown in FIG. 2, a funnel-shaped slope is bent around the opening 28 of the bucket 12, so that the coins falling along the slope are kept as close to horizontal as possible. It's Nishide. As a result, the flow of coins from inside the bucket 12 to the rotating disk 24 is extremely smooth.

The rotation circle Fj1.24 is the output shaft 32 of the gear box 32.
a mounting base 33 integrated with a sleeve fixed to a;
It is tightened and fixed between the flange 34a of the support column 34 and the flange 34a using screws. In this way, by using the mounting base 33 in which the sleeve coupled to the output shaft 32a and the receiving surface of the rotating disk 24 are integrated, assembly becomes easy and the rotating surface of the rotating disk 24 is kept constant. becomes easier to maintain.

The support column 34 extends into the bucket 12 through the opening 28 of the bucket 12, and a circular regulation plate 35 is rotatably attached to the tip end of the support column 34.

Therefore, the motor 23 connected to the gearbox 32
Even if the rotary disk 24 is rotated via the output shaft 32a, the regulation plate 35 will not be rotated integrally with the rotary disk 24. Note that the pin 36 protruding from the flange 34a of the support column 34 is rotated together with the rotating disk 24.

In the vicinity of the slit 26 formed in the guide plate 25, an elastic roller 38 made of, for example, rubber is provided.

This roller 38 sends out the coin 30 discharged from the slit 26 to the chute 14. The roller 38 is driven by the output shaft 32b of the gear box 32 via the belt 37. In addition, as shown in FIG. 3, when the roller 38 is placed above the rotating disk 24, it is preferable to prevent the roller 38 and the rotating disk 24 from coming into contact with each other. The rotation speeds of the disc 24 and the roller 38 may be adjusted relatively, and they may be kept in contact as long as their rotations do not interfere with each other.

Further, the roller 38 may be provided at a position removed from the rotating disk 24.

A coin sensor bin 40 protrudes facing the passage through which the coins 300 are sent out by the rollers 38. The coin sensor bin 40 is mounted on a lever 43 that is biased counterclockwise by a spring 42 around a shaft 41 .

Then, the coin 30a sent out by the roller 38
(FIG. 3), the chute 14 is reached after the lever 43 is swung through the coin sensor bin 40. Each time the coin 30a passes, the lever 4
3 is repeated, the number of coins 3 (la) sent out by the roller 38 can be detected by counting the number of swings of the lever 43 using the photosensor 45.

A lower end of the coin sensor bin 40 is connected to an arm of a solenoid 47. When energized, the solenoid 45 holds the coin sensor bin 40 in the attracted position and prohibits or stops the lever 43 from swinging.

The operation of the coin dispensing device 10 configured as above will be explained together with the control circuit shown in FIG. 4. As a result of playing the slot machine game, if the combination of symbols on the reels appearing on the observation window 4 corresponds to a winning, the relay drive circuit 51 is activated by the winning generation signal from the winning determination circuit 50, and the motor is activated. 23 power switch S1 is O
N and the motor 23 rotates forward.

As the motor 23 rotates forward, the gear box 32
The output shafts 32a and 32b from the rotating disk 24 are driven.
．． Roller 38 is rotated counterclockwise. Rotating disk 24
When the coin 30 is rotated, the coin 30 supplied from the opening 28 of the bucket 12 to the upper surface of the rotating disk 24 is placed on the rotating disk 24 and is rotated together with the rotating disk 24, while being rotated by the action of centrifugal force. It is moved toward the outer periphery of the plate 24.

After the outer peripheral edge of the coin 30 is received by the inner wall of the guide plate 25, the rotating disk 2 moves along the inner wall of the guide plate 25.
Rotated with 4.

Coin 30 moving along the inner wall of guide board 25
comes to the bent part 25a of the guide plate 25, the slit 26
It is sent out to the outside of the guide plate 25 through. The coin 30 that has been sent out is urged by the roller 38 and sent to the chute 14 . The liquid is discharged into the tray 13 through an opening 15 (FIG. 1) formed in the gutter 11. The length and width of the slit 26 are set to be slightly larger than the outer diameter and thickness of the coin, respectively, so that 1
Coins will be sent out one by one.

On the way from the roller 38 to the chute 14, the coin 30
a (FIG. 3) pushes away the coin sensor pin 40.

As a result, the lever 43 swings clockwise against the spring 42, and this swing is detected by the photosensor 45.

While the rotary disk 24 is rotating counterclockwise, the coins 30 are sequentially dispensed as described above, and the lever 43 swings each time. The number of swings of the lever 43, that is, the number of coins 30a sent out by the roller 38, is
As a pulse signal from the photosensor 45, the counter 52
is counted.

The prize determining circuit 50 increments the number of coins to be paid out according to the type of winning to the number of coins to be paid out setting circuit 53. When the counted value in the counter 52 and the number set up in the payout coin number setting unit 53 match, a match signal is output from the minus number setting circuit 54.

The timer 55 outputs a high level signal for a certain period of time after the coincidence signal is generated. While this high level signal is being output, the relay drive circuit 56 operates,
The motor drive switch S2 is switched from contact A to contact S. As a result, the motor 23 is momentarily reversed, and the rotating disk 24. Since the roller 38 is rotated clockwise, it is very effective in abruptly stopping the coin dispensing operation and preventing excess coins from being dispensed.

Further, by supplying the coincidence signal to the solenoid drive circuit 57 to drive the solenoid 47 and inhibit the swinging of the lever 43, the coin sensor pin 40 can prevent the coin 30 from being dispensed. Note that when an AC motor is used as the motor 23, the motor 23 can be suddenly stopped by supplying a DC current to the motor 23 at the timing when the rotating disk 24 is stopped.

When the certain period of time set in the timer 55 has elapsed, the timer 55
When the output from
will be returned to. At the same time, the relay drive circuit 56 is also turned off.
F, the motor drive switch S2 also returns to the initial position where it is connected to the terminal a. In this way, when the coin payout is completed, the counter 52. Payout number setting circuit 5
3 will be reset and return to the initial state.

By the way, in the coin dispensing device 10 described above, even when a large number of coins are stored in the bucket 12, the coin dispensing efficiency is 15 to 16 coins/second.
It is possible to maintain above. That is, a regulation plate 35 is rotatably attached to a support 34 erected on the rotary disk 24, and this regulation plate 35 receives a large number of coins stored in the bucket 12, and the rotation disk 24 receives a large number of coins. 24, so that the load due to the weight of the coin does not directly apply to it. Moreover, since the regulating plate 35 is rotatable with respect to the column 35, even if the regulating plate 35 is surrounded by a large number of coins, the rotary disk 24 can be rotated independently of this. The rotational speed of the disc 24 does not decrease.

Further, even if a large number of coins are stored in the bucket 12, the coins that have entered below the regulation plate 35 are not subjected to a very large load. Therefore, by stirring this with the bottle 36 protruding from the flange 34a of the support 34, the rotation circle +7iE24
It is possible to prevent coin jams that tend to occur near the opening 28 without substantially increasing the driving load of the bin 36. Of course, the number of bins 36 may be two or more instead of just one.

〔Effect of the invention〕

As described above, in the coin dispensing device of the present invention, a substantially horizontal rotating disk is provided below the bucket, and this rotating disk applies centrifugal force to the coins supplied from the opening below the bucket. It uses force to eject coins. Further, above the opening formed in the bucket, a regulating plate is provided which can be rotated independently of the rotating disk to prevent the weight of the coins in the bucket from being directly applied to the rotating disk. Therefore, the rotational speed of the rotating disk is increased, and a quick and smooth coin dispensing action can be obtained. Furthermore, since there is no need to arrange coin locking portions on the rotating disk as in conventional devices, the structure becomes simpler.
