Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin dispensing device having a function of automatically clearing coin jams.

[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 (
11: A coin dispensing device for discharging coins (hereinafter collectively referred to as coins) to an exit is built-in. Such a coin dispensing device is connected to a bucket that accommodates a large number of coins.

An opening is provided at the bottom of the bucket, and the coins to be dispensed are supplied to the coin dispensing device through this opening.

The coin dispensing device has a rotating disk driven by a motor, and the rotating circle +1j is driven in response to generation of a coin dispensing signal. When the rotating disk is driven, coins are ejected one by one from the ejector BJ set up around its circumference. 8. A coin sensor installed near the second discharge 11,
: Every time 1 inch is discharged, calculate the number of gl, and when the scheduled number of discharged 2 pieces is reached, stop the drive of the rotating disk.

By the way, the bucket contains a large number of coins that can be used for payouts, so there are some coins on the other hand! They overlap to form a so-called bridge, which can lead to coin jams. If a coin jam occurs again, the coins will not reach the rotary disk from the opening of the bald saw 1-1, so coins cannot be dispensed even if the rotary disk is driven.

[Problems to be Solved by the Invention] In the conventional coin dispensing device, when a coin jam as described above occurs, it is manually cleared. I'm on my way. Therefore, for example, if a coin jam occurs in a coin dispensing device used in a game machine such as a slot machine,
After interrupting J, perform the work to clear the blockage in -2. Annoyance 1: “Thank you.

The present invention is an addition to the conventional technology such as 1i4s, which has a 4' instead of I't ``r'', and when the two fins are clogged (
1-7 so that 151 errors can be automatically resolved
The objective of the present invention is to provide a two-in-one dispensing device.

[Step F to solve problems]

In order to achieve the object stated in -1-, the present invention operates the 1-in payout device, and from the first time when the payout signal +J is generated, - within a certain period of time: when the 1-in is not paid out, this is activated. When determining that a coin is jammed and dispensing two coins, the rotating disk, which is driven in the forward rotation direction, is temporarily reversed. The rotating disk, which has been temporarily reversed in this manner, is again driven in the forward rotation direction to continue dispensing coins.

According to a preferred embodiment of the invention: unloading coins;
In order to detect that no coins have been paid out within a certain period of time while the signal is being issued, a coin sensor provided to count the number of coins that have been paid out is also used. We try to avoid complicating the configuration. As this coin sensor, a general mucophoto sensor or microsinch is used, and when a coin counting signal is not continuously obtained from this coin sensor within a certain period of time, the motor that drives the rotating disk is reversed. I'm trying to make it easier.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

When a prize is obtained as a result of playing the game, a coin payout 2 device 10 is activated and the number of coins corresponding to the prize is sent out from a chute 15.

The coins sent out pass through an opening [6] formed in the gutter 11 and are dispensed into a receiving tray 14. An overflow shade 17 is provided inside the bucket 12 to guide coins inserted when the bucket 12 is full to an overflow bucket 18.

In FIGS. 3, 4, and 5 showing an example of the coin dispensing device 10, a board 22 is attached almost horizontally to the main body 2 of the slot machine.
3, and a rotating disk 24 driven by the output shaft 32a1 of the gear box 32 is provided. Further, a guide plate 2 formed in a generally cylindrical shape is provided on the substrate 22 so as to surround the periphery 21 of the rotating disk 24.
5 is fixed. A bent portion 25 a that extends inside the rotating disk 24 is formed in a part of the guide plate 25 .

There may be a gap between the h1 edge and the inner wall of the guide plate 25 as long as the radius is 1 in 30 ≧.

Group 4) Is an open rl 2 B formed on the bottom surface above λ22? A11 bucket 12 is provided, and the f and l coins stored in the bucket 12 are supplied to the rotating disk 241- through the above-mentioned interval 128. Be feared, and the 12th opening of Hano
28 and extends into Hegeno 112. A circular regulating plate 35 (C3) is rotatably attached to the distal end of the column 34. Also, a pin 36 is implanted in the lower flange 34 of the column 34.

In the vicinity of the ring 26 formed on the guide plate 25, an elastic rubber plate 38, for example, is provided. This l-7-ra 38 sends out the 1-in 30 discharged from the slit 26 to the shoe 115. The roller 38 is driven by the output shaft 32b of the gear box 32 via the heald 37.

In addition, as shown in FIG.
When placing it above i24, the roller 38
Although it is preferable to avoid contact between the rotary disk 24 and the 11+1 rotary disk 24, it is preferable to adjust the rotation speeds of the rotary disk 24 and the rotary disk 38 relatively so that the rotations of y7) and 11+1 do not interfere with each other. ,
These may be kept in contact with each other.

Further, the roller 38 may be provided at a position 1 further away from the rotation circle +2i 24.

il of 21-in 30a sent out by roller 38
A coin sensor 40 consisting of, for example, a sensor is installed facing the road. The coin sensor 40 photoelectrically detects each illumination of the coin 30a sent out by the roller 38 and outputs a detection signal. Then, by inputting this detection signal to a counter, the number of coins 30a sent out by the roller 38 can be counted.

In FIG. 1 showing the circuit configuration for driving and controlling the rotating disk 24, as a result of playing a slot machine game,
When the &FJ combination of the reel symbols appearing on the observation window 4 corresponds to a winning, the relay drive circuit 51 is activated by the coin payout signal from the winning determination circuit 50.
When the power switch S1 of the motor 23 is turned on, 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.

21-in-3 moved along the inner wall of guide board 25.
0 comes to the bending part 25a of the guide plate 25, the slit 2
6 and sent out to the outside of the guide plate 25. The coin 30 that has been sent out is urged by the roller 38 and is sent to the chute 15. The liquid is dispensed into the tray 4 through an opening 16 (FIG. 1) formed in the stem 11. Since the length and width of the slit 26 are set to be slightly larger than the outer diameter and thickness of the coin, respectively, the coins are reliably fed out from the slit 26 one by one. roller 38
Since the coin 30a (FIG. 3) passes over the coin sensor 40 on its way to the chute 15, the coin sensor 40 outputs a pulse-like detection signal. Since this detection signal is input to the counter 52, the counter 52 integrates and counts the number of coins 30a that have been paid out.

The winning determination circuit 50 sets 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.]
・Updated. When the counted value in the counter 52 and the number of coins cent-amplified by the payout coin number setting section 53 match, a match signal is output from the minus number calculation 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 is activated and the motor drive switch S2 is switched from contact a to contact i. As a result, the motor 23 is momentarily reversed, and the rotating disk 24. Since the roller 38 is rotated clockwise, the operation of dispensing coins 30 is suddenly stopped l-, and no extra coins are dispensed.

When the certain period of time set in the timer 55 has elapsed, the timer 55
When the output from the relay becomes a low level signal, the relay drive circuit 5I is turned off, and the power switch S1 is returned to the OFF position. 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. As a result, the motor 23 stops and the rotating disk 24. Roller 38 stops. In this way, when the coin payout is completed, the counter 52. The payout number setting circuit 53 is reset and returns to the initial state.

By the way, in the coin dispensing device 10 described above, even if a large number of coins are stored in the bucket I2,
The weight of the coin 30 is received and stopped by the regulating plate 35, so that a large load is not applied to the rotating disk 24. Moreover, since the regulating plate 35 is rotatable with respect to the column 35, even if the regulating plate 35 is surrounded by many coins, the rotating disk 24 can rotate independently of the coins. The rotational speed of the disk 24 never decreases. Thereby, the rotational speed of the rotating disk 24, ie, the payout speed of the coins 30, can be significantly improved.

The bin 36, which rotates together with the rotating disk 24, is connected to the bucket 1.
The coins 30 supplied from the opening 28 of No. 2 are stirred to prevent coin jamming.
Alternatively, if a coin jam occurs near the regulation plate 35, the coin 30 will not be paid out even if the coin payout signal is output from the winning determination circuit 50, and the coin sensor 40 will no longer output a detection signal. In such a state, a reverse signal is output from the coin detection time measuring circuit 60 which is activated by the coin payout signal. That is, the coin detection time measuring circuit 60 outputs a reversal signal if a detection signal is not input from the coin sensor 40 within a certain period of time after the coin payout signal is output. Incidentally, such a coin detection time measurement circuit 6
0, for example, a well-known timer circuit that measures the predetermined time using the detection signal from the coin sensor 40 as a reset signal can be used.

The thus output reverse rotation signal is held by the timer 61 for a certain period of time, and a high level signal is supplied to the relay drive circuit 56 during that time. Therefore, the motor 23, which had been rotating in the normal direction for dispensing coins, receives the reverse rotation signal from the timer 6.
While it is held at 1, it will start to reverse. As a result, the rotating disk 24 is reversed for a certain period of time, and the rotational force in the opposite direction is applied to the coin jammed area, which is very effective in clearing the coin jam. Of course, as the rotary disk 24 is reversed, the bin 36 is also reversed, so that it is possible to eliminate the coin jam at the bottom on the second day of opening.

When a certain period of time set in the timer 61 has elapsed, a low level signal is output to the relay drive circuit 56, so that the motor 232 and rotating disk 24 rotate normally again, and coin dispensing is resumed. Note that when the holding of the reverse rotation signal by the timer 61 is released, the coin detection time measuring circuit 60 is also reset.

While one coin payout signal is being generated, the number of times the reverse signal has been generated is counted by the N counter 62. When the count value of the N counter 62 reaches, for example, three times, an alarm device 63 is activated to notify of an abnormality. Therefore, it becomes possible to know that a coin jam has occurred that cannot be resolved by reversing the rotating disk 24. Note that 81 of the N counter 62
The number key is reset when the output from the -scattering output circuit 54 or the coin payout signal from the winning determination circuit 54 disappears.

Although the present invention has been described above based on the illustrated embodiment, the present invention can also be used in a conventional coin dispensing device in which the rotating disk 24 is arranged diagonally, The present invention is equally applicable not only to coin dispensing devices but also to coin dispensing devices used in various devices such as money changers using rotating discs.

〔Effect of the invention〕

According to the present invention as described above, when the coin dispensing device is operated but no coins are dispensed, the rotating disk that is rotated in the normal direction for dispensing coins is automatically rotated for a certain period of time. I'm trying to turn it upside down. By reversing the rotating disk in this way, the reversing force of the rotating disk is applied via the coin to remove coins from areas where coins tend to get jammed, such as inside the bucket or at the connection between the bucket and the coin dispensing device. It is now possible to automatically clear the blockage, eliminating the need for the complicated work that was previously required, making it extremely effective.
