[Prior art]

 Conventionally, the coins or game coins, which have been attached to a currency exchange machine or a game machine, have been accumulated in the hopper, and are mounted on a rotating disk having a trap hole provided in the hopper. A coin delivery device shown in FIG. 8 is known as a coin delivery device configured to be stacked and guided through the drop hole to the lower side of the rotating disc to be delivered. In the figure, reference numeral 1 is a coin sending device.

As shown in FIG. 8, a drive motor 3 having a drive shaft 3 a is attached to the support body 2. A rotary disc 4 having a plurality of circular drop holes 4b, ... And a stirring pin 4c protruding upward from the disc surface 4a is attached to the disc surface 4a of the drive shaft 3a. Further, guide pins 4d for sending coins are formed on the lower surface of the rotary disk 4. A hopper 5 is attached to the support body 2 so as to be attached to the rotating disk 4 in a shunt manner. The hopper 5 is composed of a supply hopper 5a for supplying coins to the rotary disc 4 and an increase hopper (not shown) for increasing the accumulated amount of coins attached to the upper part of the supply hopper 5a. A neck 5c is formed on the supply hopper 5a so as to surround the rotary disk 4. A guide surface 5d is formed on the outer peripheral portion of the upper end of the neck portion 5c so that the inserted coins are slid down to the side of the rotating disk 4 and supplied.

[0005]

[Problems to be solved by the device]

 However, the above-mentioned coin sending device 1 has the following problems. That is, there was a problem that the load on the rotating disk 4 increased as the amount of coins increased due to the mounting of the increasing hopper, and the output of the motor 3 was not sufficient. Further, as shown in FIG. 9, the pressure applied to the wall surface of the supply hopper 5a increases due to an increase in the weight of coins in the hopper 5 as the amount of accumulated coins C, ... Increases, and the rotary disk 4 becomes hollow. There was a problem that the so-called bridge phenomenon was likely to occur.

As a means for solving the above-mentioned problems, it is conceivable to increase the output of the motor or to increase the diameter of the rotating disk to widen the neck portion of the hopper, but both of them are costly to manufacture. It has the drawback of becoming expensive. Therefore, as a method of suppressing the bridging phenomenon, a method is employed in which a stirring rod is provided at the center of the rotating disk so that the coin bridge state is destroyed. However, with this method, the coin is pinched between the stirring rod and the neck of the hopper, or between the stirring rod and the side of the coin drop hole, which hinders the rotation of the rotating disc and causes the coin to rotate. There is a problem that the transmission is not performed properly.

On the other hand, as shown in FIG. 10, a method of providing a protrusion 6 on the wall surface surrounding the rotating disk 4 of the supply hopper 5a can be considered as a measure for reducing the load of the coin. However, according to this method, the coin C is fitted under the protrusion, and the pushing force of the coins D, D on the lower side is not released, so that the rotating disk 4 is overloaded or the coin D is caught. Similarly, there is a problem that the rotation of the rotating disk 4 is hindered and coins are not properly delivered.

The present invention has been made in view of the above-mentioned problems, and the rotating disks are not overloaded by the coins accumulated in the hopper, and the occurrence of the bridge phenomenon or the trapping of the coins is suppressed. It is an object of the present invention to provide a coin sending device that can appropriately send coins.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 4 show a first embodiment of the present invention. The same parts as those in FIG. 8 shown as the conventional example are designated by the same reference numerals. As shown in FIG. 1, the support body 2 is provided with a top plate 2a inclined with respect to a horizontal plane, and a hopper 5 is attached to the top plate 2a. A rotating disk 4 (see FIG. 2) is arranged in the hopper 5 so as to be driven to rotate, and a wire 7 (linear body) having rigidity is supported by the hopper 5 in a cantilevered manner.

As shown in FIG. 2, a drive motor 3 is fixed to the support body 2 with its drive shaft 3a protruding from the top plate 2a. A rotary disk 4 is supported on the drive shaft 3a. Coin dropping holes 4b, ... Are formed in the disc surface 4a of the rotating disc 4. A stirring pin (projection) 4c for stirring the coin is formed between the dropping holes 4b ,. Further, guide pins 4d, ... For sending coins are formed on the lower surface of the rotary disk 4 between the holes 4b ,.

A hopper 5 is provided on the top plate 2a of the support 2 so as to be connected to the rotary disk 4, and the hopper 5 supplies the coins on the supply hopper 5a that supplies coins to the rotary disk 4. An increasing hopper 5b for holding a large amount can be attached (see Fig. 1). The supply hopper 5a is provided with a step portion 5e surrounding the rotating disk 4 to suppress the eccentricity of the rotating disk 4. A guide surface 5d is formed on the outer upper portion of the outer circumference of the rotating disk 4 so that the coins fed into the rotating disk 4 slide down and are supplied.

As shown in FIG. 5, a groove 5h is formed in the upper edge portion of the supply hopper 5a, and a linear body 7 having a coil spring 8 (elastically deformable portion) at a base end portion 7a is formed in the groove 5h. It is fitted and is horizontally screwed so as to traverse just above the rotating disk 4 and cantilevered by the supply hopper 5a. In this case, in addition to the effect of the first embodiment, the linear body 7 extending linearly becomes appropriate by the coil spring 8 formed at the base end portion 7a, and the restoring force thereof causes the hopper 5 to return. Effectively move the coins inside.

In the second embodiment described above, the linear body 7 having the coil spring 8 at the base end 7a is used, but the base end is elastically deformed by interposing another elastic material. It may be a feasible part.

Further, in the coin sending device 1 of the first and second embodiments, the linear body has a linearly extending shape. However, the linear body is not limited to the linear shape, and the coiled shape, the corrugated shape, It may have a sawtooth shape or the like.

In the coin dispensing device 1 of the first and second embodiments, the linear member 7 is cantilevered so as to cross the side wall of the supply hopper 5a and directly above the rotary disk 4, respectively. As shown in FIG. 6, the linear body 7 may be supported in a cantilever manner so as to cross the straight wall surface of the supply hopper 5a and directly above the rotating disk 4.

Further, in the first and second embodiments, only one linear body 7 is supported in a cantilever manner, but the number of linear bodies 7 is not limited to one, and for example, as shown in FIG. In addition, the linear body 7 is placed directly above the rotating disk 4, and another linear body 9 is placed on the guide surface 5d so as to face the linear body 7 and cantilevered to support the guide surface. By smoothing the supply of coins from 5d, the supply amount of coins to the rotating disk 4 can be adjusted. Further, the linear body may be supported by the increasing hopper 5b (see FIG. 1) in a cantilever manner.

It goes without saying that it does not depend on the coin delivery means by the rotating disc, the arrangement of the rotating disc (for example, the rotating disc is arranged in a horizontal state, etc.), or the shape of the hopper.
