[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hopper device for storing coins of a small disc body in a stacked state and discharging the coins one by one.
In particular, the present invention relates to a coin hopper device having an increase tank for storing a large number of coins in a stacked state.
The term “coin” in the present specification includes, as a matter of course, a coin that is a currency and a small disk such as a game medal or token.
[Prior art]
[0002]
Various types of such coin hopper devices have been known.
For example, Japanese Patent Application No. 10-170446 by the applicant of the present application shows a medium-sized coin hopper device.
Here, the hopper apparatus will be schematically described with reference to FIG. 3 of the accompanying drawings.
First, the large square at the bottom of FIG. 3 is a pair of leg frames 1 constituting a coin hopper device.
A rectangular substrate 2 is fixed horizontally above the leg frames 1.
The slightly large rectangle below FIG. 3 is the electric motor 3.
[0003]
The electric motor 3 is attached to the lower surface of the substrate 2 with a thick plate gear box 4 interposed therebetween.
The gear box 4 has a first rotating shaft 5 and a second rotating shaft 6.
The first rotating shaft 5 passes through substantially the center of the substrate 2 to be rotatable.
A disk 7 for paying out coins C is attached to the tip of the rotating shaft 5.
In other words, the disk 7 for paying out coins C is rotatably disposed on the upper surface of the substrate 2.
[0004]
A substantially trapezoidal tank in the center of FIG.
A small opening 8B below the tank 8 surrounds the rotatable disk 7 and is attached to the substrate 2.
Therefore, the tank 8 has a large opening 9 on the upper side.
A slightly large rectangular shape in the upper part of FIG. 3 is an auxiliary tank 10 having a rectangular tube shape.
The auxiliary tank 10 has a concave and convex biting structure at the opening edge below the auxiliary tank 10.
[0005]
Note that the opening edge below the auxiliary tank 10 is fixed via a concave-convex biting structure at the opening edge above the tank 8.
The auxiliary tank 10 includes a square cylindrical peripheral wall 11 and an inclined plate 12 that seals half of the lower opening.
Three sides of the rectangular inclined plate 12 are coupled to the inner surface of the peripheral wall 11 and the remaining bottom side forms part of the opening.
Accordingly, the auxiliary tank 10 has a large opening 13 on the upper side and a small opening 14 on the lower side.
[0006]
A second auxiliary tank 15 is appropriately attached to the upper opening 13 of the auxiliary tank 10 in the same manner.
The second rotating shaft 6 of the gear box 4 penetrates the substrate 2 in a rotatable manner.
A long stirring shaft 16 is attached to the tip of the rotating shaft 6. The stirring shaft 16 passes through the bottom wall 8A of the tank 8 so as to be rotatable. The stirring shaft 16 has a length such that its upper end is located near the opening 9 of the tank 8. Further, one end of a bent spring 17 is fitted on the tip of the stirring shaft 16. The spring 17 has a slightly long original end of a screw 18 fitted therein.
[0007]
In the conventional example described above, a large amount of coins are stored in the tank 8 and the auxiliary tanks 10 and 15 in a stacked state, and the electric motor 3 is driven. When the electric motor 3 is rotated, the coins C are discharged one by one by the disk 7 rotated as shown on the left side of FIG.
On the other hand, the stirring shaft 16 is also rotated so that the screw 18 rotates in an inverted conical shape above the small opening 14. As a result, even if a large number of coins C overlap each other and a coin bridge is formed between the peripheral wall 11 and the inclined plate 12, the coins C are destroyed.
[0008]
However, there is a problem that a coin bridge is formed on the inner bottom of the tank 8.
In other words, there is a problem that a coin bridge is formed across the small opening 8B in the tank 8.
Specifically, there is a problem in that an arch bridge formed by a large number of coins is formed between the inclined bottom walls 8A and 8C in the tank 8 so that the coins do not fall.
That is, there is a problem that coins are not paid out even though there are coins in the tank 8.
[Problems to be solved by the invention]
[0009]
An object of the present invention is to provide a hopper device that can smoothly and smoothly discharge coins without interruption.
In other words, an object of the present invention is to prevent a coin bridge from being formed across the payout disk below the tank.
Specifically, it is an object of the present invention to eliminate the problem that coins do not fall due to the formation of an arch bridge formed by a large number of coins on an inclined bottom wall in a tank.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on its implementation with reference to the accompanying drawings. FIG. 1 is a side view schematically showing an embodiment according to the present invention. FIG. 2 is an enlarged perspective view showing a main part of FIG. This embodiment, as is apparent from a comparison between FIG 1 and the conventional example 3 of is disposed a cross plate 21 shield the coins in a transparent tank 8.
[0012]
Shield sectional plate 21 is made of a rectangular plate made of metal or resin (see Figure 2). And at each corner of Saido sectional plates 21 shield is formed by protruding pivot 22. Also at each corner of the other side of the shield cross plate 21 projection 23 are formed. Sectional plates 21 shield the coin is disposed above the tank 8 so as to cover almost half of the disk 7.
For example, in the case of FIG. 1 cross plate 21 shield near the tank 8 left end wall is provided. That is, a pair of openings is formed at the edge of the large opening 9 above the tank 8, and the pivots 22 are rotatably fitted in the openings.
[0013]
The projections 23 of the cross plate 21 shield the elongated hole 24 in each side wall of the tank 8 is formed respectively extends through movable. Further, a pair of hooks 25 are formed on the tank 8 wall below the pivot 22 so as to protrude outward. Long springs 26 are spanned between the hook 25 and the protrusion 23. A slightly larger rectangular shape in the upper part of FIG. This rectangular tank 31 is for increasing the amount of coins stored. The tank 31 has an uneven biting structure at the opening edge below the tank 31.
[0014]
The opening edge below the increase tank 31 is fixed via a concave / convex biting structure on the opening edge above the tank 8.
In the present embodiment configured as described above, a large amount of coins are first stored in the tank 8 and the increase tank 31 in a stacked state. When a large number of coins are stored in the tanks 8 and 31, the blocking plate 21 is moved to the position of the one-dot chain line in FIG. At this time, a space without coins is formed below the blocking plate 21.
[0015]
In other words, the weight load of the coin does not partially affect the disk 7 below the blocking plate 21.
When the electric motor 3 is rotated in this state, the coins C are discharged from the hopper device one by one by the rotating disk 7 (see the left side in FIG. 1).
Thus, since the amount of coins with respect to the disk 7 is limited by the blocking plate 21, the coin C is smoothly discharged.
That is, since the amount of coins on the disk 7 is limited, an arch-shaped bridge made of a large number of coins is not formed between the bottom walls 8A and 8C in the tank 8.
[0016]
In addition, since the blocking plate 21 can move within the range of the long hole 24 around the pivot 22, no coin bridge is formed between the bottom plate 8C.
Further, since the shielding plate 21 is movable, the shielding plate 21 absorbs even if there is an impact due to the rotation of the disk 7 and the coin group on it.
In this case, even if there is a large impact on the blocking plate 21, the impact is easily absorbed because of the spring 26.
On the other hand, when the stirring shaft 16 is rotated via the gear box 4, the screw 18 rotates in an inverted conical shape above the right side of the opening 9.
[0017]
Therefore, even if a coin bridge is formed between the blocking plate 21 and the peripheral walls of the tanks 8 and 31, it is broken by the stirring shaft 16 and the screw 18.
As a result, the coin hopper device can discharge coins smoothly without interruption, in other words, without interruption.
【The invention's effect】
The present invention as described above can prevent a coin bridge from being formed above the disk on the inner bottom of the coin tank by adding a simple structure. For this reason, according to the coin hopper device of the present invention, it is possible to obtain a great effect that a large number of coins can be constantly and continuously discharged.
