Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention relates to a coin hopper that is used, for example, built into a game machine that dispenses coins.

``Prior Art'' As a conventional coin hopper of this type, one is known in which a hopper body is equipped with a disk for stirring coins.

``Problems that the invention seeks to solve'' However, such conventional coin hoppers have problems with metal powder (coins colliding with each other) that is generated when coins are stirred by the disk inside the hopper body. (coin powder produced by)
As a result, when a player holds the dispensed coins in his/her hands, there is a problem in that the player's hands become dirty with the powder or the coins get jammed in the coin hopper.

``Means for Solving the Problems'' However, the present invention equips the hopper body with a disk that stirs coins in the vertical direction, and drills holes for metal powder removal in the coin reservoir at the bottom of the hopper body. , a means for forcibly removing the metal powder is provided which causes air to flow in the vertical direction from the inside of the hopper body to the outside through the hole.

``Function'' Therefore, according to the present invention, the metal powder generated inside the hopper body can be removed to the outside of the hopper body through the holes, and as a result, it is possible to prevent coins from becoming dirty and to prevent coin jamming. In particular, since the air flow is caused in the same direction as the coin stirring direction, the air flow is actively carried out from between the coins toward the holes without being obstructed by the coins. It can further improve the ability to remove metal powder,
It is possible to reliably obtain the above-described effect of preventing coin dirt and coin jamming.

"Embodiments" Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is a cross-sectional view of a coin hopper according to the present invention. In the figure, 1 is a hopper main body having an opening 1a at the upper end, and a coin insertion slot 2 into which a coin C is inserted into the shoulder of the upper end of the hopper main body 1. At the same time, a disk 3 for stirring the coin C is installed on the right side of the hopper main body 1 in the drawing.

This disk 3 has a well-known structure in which pins 6 (only two are shown in the drawing for convenience of illustration) are set up at equal intervals on a disk 5 that is rotated by a motor 4.

Coin reservoir portion 1b at the bottom of the hopper body 1
A hole 7 for removing metal powder is bored in the hole 7.
Here, the holes 7 can be round holes, square holes, slit-like elongated holes, etc., and various arrangement means such as multiple rows in parallel or multiple rows in a staggered manner can be used.

Further, a hose 8 for drawing out the metal powder is attached to the lower part of the hole 7, while a means for forcibly removing the metal powder is provided through a hood 9 to the upper end opening 1a of the hopper main body 1 facing the hole 7. Juan 10
is installed.

The illustrated embodiment is configured as described above,
The action will be explained below.

Now, when the coins C in the hopper body 1 are stirred up and down by the disk 3 (actually, there are a huge amount of coins C in the hopper body 1, only four are shown in the drawing for convenience of illustration). , the same hopper body 1
Inside, the coins C collide with each other and metal powder is generated.

This metal powder is removed to the outside of the hopper main body 1 through holes 7 formed in the coin storage portion 1b, and is discharged through a hose 8. Here, when the fan 10 is rotated, the metal powder is forcibly moved by the wind generated by the fan 10, that is, the vertical air flow passing from the inside of the hopper body 1 to the outside through the holes 7. Since the coins C are removed to the outside of the hopper main body 1 through the holes 7, it is possible to prevent the coins C from becoming contaminated with powder or from coin clogging.

FIG. 2 is a sectional view showing another embodiment. In this embodiment, instead of using the fan 10, a suction device 11 is connected to the hose 8, and the suction device 11 is driven. The same air flow as in the example is generated, and the metal powder generated in the hopper body 1 is forcibly sucked into the hose 8 through the holes 7, and the powder is removed from the hopper body 1. Since the other points are the same as the embodiment shown in FIG. 1, the same parts in FIG. 2 as in FIG.

"Effects of the Invention" As is clear from the above embodiments, the present invention is equipped with a disk 3 that stirs coins C in the vertical direction in the hopper body 1, and removes metal powder from the coin reservoir 1b at the bottom of the hopper body 1. In addition to drilling holes 7 for use in the hopper body 1, it is also provided with means 10 and 11 for forcibly removing metal powder that causes air to flow in the vertical direction from inside the hopper body 1 to the outside through the holes 7. The metal powder generated inside the hopper main body 1 can be removed to the outside of the hopper main body 1 through the holes 7..., and as a result, it is possible to prevent the coin C from getting dirty and also prevent coin jamming. There is an effect that can be done.

In particular, since the air flow is caused in the same direction as the stirring direction of the coin C, the air flow is not hindered by the hopper C and the holes 7...
It is actively carried out to improve the ability to remove metal powder, and has the remarkable effect of reliably achieving the above-mentioned effect of preventing dirt on coin C and preventing coin clogging. be.
