DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin discharging device incorporated in a money changing machine, various vending machines, and the like.

[0002]

Generally, in a vending machine provided with a mechanism for exchanging bills into coins or a mechanism for dispensing coins as change, coins are supplied to a coin hopper prepared for each denomination. The coin hopper is provided inside the coin hopper so that coins can be sent out from the coin hopper when necessary. FIGS. 3 and 4 show the coin discharging device 1, wherein a coin hopper 2 whose upper portion is largely open as a coin slot, and a coin feeding portion 4 which is connected to a lower opening 3 of the coin hopper 2. It consists of The lower opening 3 of the coin hopper 2 is inclined, and the coin feeding portion 4 connected to the inclined lower opening 3 has opened a plurality of coin introduction holes 5 corresponding to the circular shape of coins of a specific denomination. A disk-shaped rotor 6 is rotatably provided on a coin receiving surface 7, and the rotor 6
Is positioned in the lower opening 3, and when a coin enters each coin introduction hole 5 of the rotor 6 that rotates by receiving power from the drive motor 8, the coin is discharged from the coin delivery unit 4 by rotation of the rotor 6. It was provided so as to guide toward Road 9.

In the coin discharging apparatus having the above-mentioned structure, the rotor rotates at a high speed when a large number of coins need to be sent out per time, such as a money changer. Is provided so that it can be discharged. When the rotation speed of the rotor is high, coins in the vicinity of the rotor are often stirred by the rotation of the rotor, and the coins enter the respective coin introduction holes properly. As shown in FIG. 5, there is no coin remaining phenomenon in which a plurality of coins a are abutted in one coin introduction hole 5 and are not sent out from the rotor. On the other hand, there is also provided a coin discharge device in which the rotation speed of the rotor is reduced in accordance with the fact that the above-described coin discharge device having a high rotation speed of the rotor is relatively expensive and the number of coins discharged per hour is reduced. . In such a device that sends out a small amount of coins per hour (for example, a device that sends out coins at a rate of about 2 / sec), the amount of coins remaining in the coin hopper is small because the amount of coin rotation by the rotor is small. When the number of coins decreases, the above-mentioned remaining coins are likely to occur. That is, even if a plurality of coins abut each other in such a way as to enter one coin introduction hole, the state is not destroyed because there are few other coins in contact with these coins,
It starts to rotate while riding on the rotor. for that reason,
As shown in the figure, a coin leveling bar 10 made of an elastic material extending toward the rotor is provided in advance to prevent a plurality of coins from abutting on the coin introduction hole. However, in a device equipped with a coin leveling bar, the coin leveling bar is arranged so as to descend at right angles to the upper surface of the rotor, so that coins remain between the rotor and the coin leveling bar. The coin lock phenomenon may be induced, and when the coin lock phenomenon occurs, there is a problem that it becomes difficult for coins to enter each coin introduction hole. Further, since the coin leveling bar is fixed to the coin hopper in advance, when a certain amount of coins is in the coin hopper, the coin turning bar becomes an obstacle to the coin by rotating the rotor. There was a problem that the stirring action could be impaired. Therefore, the present invention has been made in view of the above-described circumstances, and in a coin discharging device in which the rotation speed of the rotor is low, in order not to impair the stirring action of the rotor, and in a state where a plurality of coins abut against the coin introduction hole of the rotor. It is an object of the present invention to break the butted state of coins without causing a coin lock even when the coins enter, so that coins can be properly ejected.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has a coin-shaped rotor provided with a plurality of coin-introduced holes in a lower opening of a coin hopper so as to be rotatable. A coin discharging device in which a feed-out portion is arranged, coins fed into the coin hopper enter a coin introduction hole of a rotating rotor, and the coin is fed in a predetermined direction by rotation of the rotor. The present invention solves the above-mentioned problem by providing a coin discharging device, wherein a coin leveling means protruding in a state close to the rotor is provided on an upper surface of the coin discharging device so as to be able to enter and exit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. In addition, the same reference numerals are given to portions having the same configuration as the conventional example shown in FIGS. 3 to 5, and the description is omitted. In the coin discharging device 1 of the present invention, the coin hopper 2 is provided with coin leveling means 11. The coin leveling means 11 is composed of a coin leveling rod 12 which is arranged so as to be able to be taken in and out of the coin hopper 2. The coin leveling means 11 projects on the upper surface of the rotor 6 in parallel with and close to the rotor 6. A drive source 13 composed of a solenoid or the like is connected to the coin leveling bar 12 via a link 14 so that the coin leveler can be moved backward so as not to be positioned on the upper surface of the rotor 6. The rod 12 is provided so as to enter and exit. The coin leveling bar 12 is preferably an elastic body made of, for example, a rubber material, but is not limited to the elastic body. Coin leveling means 1 as described above
1 protrudes above the upper surface of the rotor 6, and is provided so as to advance toward the rotation center side of the rotor 6 and be positioned on the movement locus of the coin introduction hole 5.
When the coin leveling means 11 is located on the movement trajectory of the coin introduction hole 5 and comes close to the upper surface of the rotor 6, a plurality of coins are supposedly inclined into one coin introduction hole 5 and mutually enter each other. Even when the coins are in a butted state, the coins are projected from the upper surface of the rotor 6, so that the coins collide with the coin leveling means 11 and the coins are reliably broken. In the above example, the coin leveling means 11 advances toward the rotation center side of the rotor 6, but if the coin leveling means 11 advances on the rotation trajectory of the coin introduction hole 5, a plurality of Since the butting state of the coins can be broken, the direction in which the coins move forward may be an oblique direction that deviates from the center of rotation of the rotor as indicated by the imaginary line 11 '.

In the figure, reference numeral 15 denotes a remaining coin amount detecting means for detecting whether or not the remaining amount of coins inside the coin hopper 2 exceeds a certain fixed amount. Information is sent to the drive source 13 as a signal, and the coin leveling means 11 protrudes when the remaining amount of coins falls below a predetermined amount, and the coin leveling means 11 is retracted when the remaining amount of coins exceeds the predetermined amount. In a standby state. Like this, coin hopper 2
Coin leveling means 1 when the number of coins in
Conventionally, since 1 comes to protrude above the rotor 6,
It is possible to prevent the phenomenon of remaining coins, which tends to occur when the number of coins is small, and when the coin hopper 2 contains many coins, the coin leveling means 1
1 is retracted so that coins can easily move inside the coin hopper 2 so that the stirring action due to the rotation of the rotor is not impaired. In the drawing, reference numeral 16 denotes a coin discharge detecting means provided in the discharge path 9 of the coin feeding section 4 for detecting the presence or absence of a discharged coin and transmitting the information as a signal to the drive source side. During the rotation operation of the rotor, when the ejection of coins is not detected for a predetermined time or more, the coin leveling means 11 is made to protrude, the remaining coins are eliminated, and the discharge of coins for a predetermined time or more is detected. In such a case, the coin leveling means 11 is provided so as to be retracted to be in a standby state. The above-mentioned coin remaining amount detecting means and coin discharge detecting means are not always required, but by providing these means, it becomes possible to quickly cope with the occurrence of a coin remaining phenomenon.

[0007]

As described above, according to the coin discharging device of the present invention, the coin delivery portion having a rotatable disk-shaped rotor having a plurality of coin introduction holes formed in the lower opening of the coin hopper. Is arranged, the coins fed into the coin hopper enter the coin introduction hole of the rotating rotor, and the coins are sent out in a predetermined direction by the rotation of the rotor, wherein the upper surface of the rotor A coin leveling means protruding in a state close to the rotor is provided so as to be able to enter and exit. Since the coin leveling means can be put in and taken out in a state close to the upper surface of the rotor,
By causing the coin leveling bar to protrude above the upper surface of the rotor when a coin remains, a plurality of coins abut a state where a coin remains on the rotor or one coin introduction hole. It is possible to surely break the state of being left in, and to eliminate the coin remaining phenomenon. If a large number of coins are stored in the coin hopper, the coin leveling means is made to wait for the coin to move backward in the coin hopper by the rotating rotor. Can be discharged, and an effect excellent in practicality is exhibited.
