Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a coin payout apparatus used for various kinds of coin exchange machines, slot machines and medal lending apparatuses in game arcades, and the like.
[0002]
[Prior art]
For example, as shown in FIG. 3, such a coin payout apparatus is disposed below a bucket 1 in which a large number of disc-shaped coins (including medals and tokens) 13 having a constant outer diameter are randomly accumulated. 13 are sent out one by one to the lower tray 10, and the supply port 2 formed at the bottom of the bucket 1 is opened on the coin payout device 3 below. The bucket 1 is detachably connected to the coin payout device 3 by a bearing 14 and a latch 15, and is configured to be easily and easily removed at the time of maintenance or the like.
[0003]
Further, an inclined plate 24 for reducing the load of a coin applied to the turntable 6 described below is projected from the inner wall of the bucket 1 toward the upper side of the supply port 2. It extends beyond the boss 8 to the vicinity of the outer peripheral portion on the opposite side.
[0004]
The coin payout device 3 includes a base 4 having an upper surface inclined at a constant angle, an inclined base 5 having a circular concave portion attached to the inclined surface of the upper surface, and a rotatable mounting in the concave portion of the inclined base 5. The main component is a rotary disk 6 having a plurality of coin receiving holes 23 formed therein and having an inner diameter slightly larger than the outer diameter of the coin 13. As is apparent from FIG. A cylindrical ring 12 for coin guide manufactured separately from the turntable 6 is arranged and fixed on the outer periphery of the turntable 6 with a part of its lower edge covering a part of the outer periphery of the turntable 6. A supply port 2 for coins 13 formed at the bottom of the bucket 1 is opened at the upper part of the ring 12.
[0005]
The base 4 is provided with a motor 7 as a drive source. A drive shaft of the motor 7 is provided with a nut 16 and a collar 17 on a rotation shaft 9 attached to a boss 8 formed at the center of the turntable 6. And the rotation of the motor 7 is transmitted to the turntable 6 via the rotation shaft 9 and the boss 8.
[0006]
With such a configuration, most of the coins 13 supplied into the bucket 1 once fall on the inclined plate 24 and then fall on the turntable 6.
[0007]
In order to send out the coins 13 in the bucket 1 to the tray 10 by the coin payout device 3, first, the motor 7 is driven to rotate the turntable 6, and the coins 13 accumulated in the bucket 1 are moved to the inclined base 5. The coins are dropped one by one into each coin receiving hole 23 of the rotary disc 6 along the surface of the rotary disc 6 and are sent out to the lower tray 10 via the carrying-out path 11 communicating with the coin receiving hole 23.
[0008]
In the above-described delivery mechanism, since the diameter of the coin receiving hole 23 provided in the turntable 6 is slightly larger than the diameter 13 of the coin, the coin 13 has already fallen into the coin receiving hole 23 and has been loosely fitted. Often, another coin 13 was caught between the loosely fitted coin 13 and the inner peripheral wall of the ring 12, and the turntable 6 often became unable to rotate.
[0009]
For example, as shown in FIG. 4, when a state occurs in which the coin 13 contacting the inner peripheral wall of the ring 12 is pressed with the other end of the coin contacting the boss 8 with one end inclined. Since the ring itself does not rotate, a large frictional resistance is generated between the ring 12 and the rotary disk 6, and a large load acts on the rotary disk 6 to hinder the smooth rotation of the rotary disk 6, thereby causing a so-called vertical jam. As a result, the turntable 6 may not be able to rotate.
[0010]
In order to solve such an inconvenience, the diameter of the coin receiving hole 23 may be substantially the same as that of the coin 13 to eliminate the gap between the loosely-fitted coin 13 and the outer wall 12. The coins 13 accumulated in one portion hardly fall into the coin receiving hole 23 of the turntable 6, which causes a problem that the sending efficiency is reduced.
[0011]
Furthermore, the coin 13 that has fallen partway into the coin receiving hole 23 provided in the rotating disk 6 reaches the coin outlet of the rotating disk 6, and the coin 13 is pinched by the inclined base 5 so that the rotating disk 6 cannot rotate. There were many things.
[0012]
Therefore, for example, in Japanese Unexamined Patent Publication No. 7-85333 (Patent Document 1), as shown in FIG. 5, as a means for preventing the coin 13 from standing up, the outer peripheral portion of the turntable 6 is gently turned outward. In addition to the upwardly inclined portion 18, the central portion of the outer periphery of the boss 20 is also formed in the inclined portion 19 gently downwardly inclined from the center toward the coin receiving hole 23, so that the coin 13 is A hopper device has been proposed which falls smoothly into the inside and prevents vertical clogging.
[0013]
[Patent Document 1]
JP-A-7-85333 (Claims, FIG. 5)
[0014]
[Problems to be solved by the invention]
However, even if the inclined portion 19 is formed on the boss 20 as in Patent Document 1, the entire boss 20 protrudes greatly, so that the portion of the boss 20 becomes an obstacle to completely prevent the coin 13 from becoming clogged vertically. Was difficult to prevent.
[0015]
If the boss 20 which causes the vertical jam of the coin is eliminated, a fundamental solution can be achieved. However, the strength of the turntable 6 is secured, and the nut 16 and the collar 17 for fixing to the drive shaft of the motor 7 are protected. Therefore, the boss 20 is indispensable, and further, the provision of the inclined portions 18 and 19 causes an increase in the size of the turntable 6.
[0016]
Furthermore, as shown in FIG. 3, the fact that the tip of the inclined plate 24 is located near the outer periphery on the opposite side beyond the center boss 8 of the turntable 6 means that the load of the coin 13 However, the coin 13 is concentrated on the outer peripheral portion of the turntable 6 to cause vertical clogging.
[0017]

Hereinafter, an embodiment of a coin payout apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an enlarged cross-sectional view of a main part in an embodiment of the coin payout apparatus of the present invention, FIG. FIG. 4 is an explanatory view showing the relationship between members constituting the main part, and the same reference numerals are given to the same components as those in the conventional example shown in FIGS. Note that the entire structure of the coin payout apparatus is the same as that described with reference to FIG. 3, and thus a detailed description thereof will be omitted.
[0030]
The coin payout apparatus 3 of the present invention is also provided below the bucket 1 in which a large number of coins (including medals and tokens) 13 having a constant outer diameter are randomly accumulated, and the coins 13 are placed one by one on a tray 10 below. The supply port 2 formed at the bottom of the bucket 1 is open to the coin payout device 3 below.
[0031]
A coin guide plate 22 is provided on the inner peripheral wall of the bucket 1 to guide the inserted coin toward the upper side of the supply port 2 and to prevent the load of the coin from acting on the entire surface of the turntable 6 at one time. The coin guide plate 22 is disposed so as to be orthogonal to the axis of the boss provided on the turntable 6, and the length thereof is set so that the tip end is located within the radius of the turntable 6. I have.
[0032]
As shown in FIG. 3, the coin payout device 3 includes a base 4 having an upper surface inclined at a constant angle, an inclined base 5 having a circular concave portion attached to the inclined surface of the upper surface, and The rotating disk 6 rotatably mounted in the concave portion of the inclined base 5 is a main component, and the supply port 2 of the coin 13 formed at the bottom of the bucket 1 is opened at the upper part of the rotating disk 6, A plurality of coin receiving holes 23 having an inner diameter slightly larger than the outer diameter of the coin 13 are formed in the turntable 6.
[0033]
An arc-shaped peripheral wall is vertically provided along a part of the outer periphery of the coin receiving hole 23 on the lower surface of the rotating disk 6 so that the coin 13 discharged from the coin receiving hole 23 can be rotated in the rotating direction of the rotating disk 6. It works to send out smoothly.
[0034]
Further, the base 4 is provided with a motor 7 as a drive source, and a drive shaft of the motor 7 is provided with a bolt 16 and a nut 17 on a rotation shaft 9 attached to a boss 8 formed at the center of the turntable 6. And the rotation of the motor 7 is transmitted to the turntable 6 via the rotation shaft 9 and the boss 8.
[0035]
According to the present invention, in the coin payout apparatus 3, the rotary disk 6 is formed integrally with a peripheral wall 21 having an inner peripheral wall orthogonal to an inner bottom surface along an outer peripheral edge thereof.

The height A of the peripheral wall 21 is formed to be slightly higher than the height B of the boss 8 formed at the center of the turntable 6. ing.
[0036]
When the coin 13 is inserted into the bucket 1 of the coin payout device 3 configured as described above, the coin 13 falls on the coin guide plate 22 and then falls on the turntable 6 sequentially. Since the tip of the coin guide plate 22 is located below the center boss 8 and below the turntable 6 and within a radius of the turntable 6, the coin 13 may fall onto the entire turntable 6 at one time. There is no. Furthermore, since a constant gap is formed between the lower portion of the coin guide plate 22 and the inner peripheral wall of the bucket 1 so that coins cannot enter, the load of the coin does not act on the entire surface of the turntable 6 at once, and the coin is rotated with small power. The board can be rotated smoothly.
[0037]
In order to send out the coins 13 accumulated in the bucket 1 to the tray 10, if the motor 7 is rotated in the same manner as in the prior art, the turntable 6 is rotated and the coins 13 are placed on the surface of the inclined base 5.
