Description

  The present invention relates to a hopper device for storing a plurality of coins in a stacked state and feeding the coins one by one. Specifically, the present invention relates to a coin hopper device used in a vending machine including a medal lending machine, a currency change machine, a game machine using a medal, or the like. In particular, the present invention relates to a small coin hopper device suitable for a change machine used in a large retail store, a change machine for a vending machine, or the like. Note that the term “coin” in the present specification includes, as a matter of course, coins as currency, small disk-shaped medals, tokens, chips and the like used for games and the like.

For example, a relatively small coin hopper device is disclosed in an application filed by the present applicant (Patent Document 1).
FIG. 4 is a schematic perspective view of a coin hopper device with an escalator disclosed in this prior art.
The hopper device H stores a large number of coins (not shown) in a funnel-shaped hopper tank T and discharges the coins one by one obliquely upward.
That is, an electric motor device E having a gear train is attached below the base plate B disposed obliquely.
Then, the electric motor device E rotates the disk D in the bottom of the hopper tank T.
Coins are pushed obliquely upward along the base plate B through the through hole (not shown) of the rotating disk D and discharged out of the hopper tank T.
Coins pushed out from the hopper device H are transferred upward through the escalator device 10.

Japanese Patent Application No. 10-254512 (FIGS. 1-7, paragraphs 0001-0033)

In the conventional hopper device H, as described above, the electric motor device E with a gear train is installed below the base plate B, and the hopper tank T is installed on the base plate B.
Therefore, the hopper device H has a problem that it becomes large in the vertical direction as shown in FIG.
For example, in order to reduce the size of the hopper device, there is a type in which the base plate B is horizontal and the electric motor device E and its gear train are disposed below the base plate B.
However, the above arrangement has a limit in reducing the size of the coin hopper device.

The present invention was developed for the purpose of downsizing a coin hopper device.
In particular, the present invention was developed for the purpose of reducing the height of the coin hopper device as much as possible.

In order to achieve the above object, the present invention has the following configuration.
A rectangular bottom plate having a substantially box shape, an electric motor disposed on one end of the bottom plate with the projecting end of the rotating shaft positioned downward, and mounted so as to cover the bottom plate except for the electric motor A base plate having a box shape substantially the same shape as the bottom plate, a ring portion projecting from one end portion of the base plate and penetrating and holding the electric motor, and fixed to a projecting end of a rotating shaft of the electric motor First gear means, disk means arranged on the bottom of a hopper for storing coins for discharging the coins one by one, second gear means for rotating the disk means, Gear train means for connecting the second gear means and the first gear means, wherein the first gear means, the second gear means and the gear train means are connected to the bottom plate and the base plate. Arrayed in the internal space between the And a coin counting sensor on the side of the coin outlet facing the electric motor, the coin outlet being formed near the ring portion of the base plate. A coin hopper device is provided.

  The present invention is the coin hopper device, wherein the electric motor means is disposed on the side of the disk means.

In the present invention, the first gear is rotated when the electric motor is rotated.
When the first gear means is rotated, the gear train means is rotated.
The second gear means is rotated via the gear train means.
When the second gear is rotated, the disk means is rotated through the rotating shaft.
As a result, a plurality of coins in the hopper are paid out one by one to the outlet by the disk.
That is, when the electric motor is rotated, the coin is inserted into one of the through holes of the rotated disk.
The lowermost coin inserted in the through hole slides on the upper surface of the base plate through the claw by the rotation of the disk.
Coins that are slid on the upper surface of the base plate by the disk are guided in the exit direction by the inner wall of the hopper and the guide pieces.
The coin guided in the exit direction is pushed out from the position of the through hole.
Coins pushed outward are pushed further outward.
According to the present invention, as a result of devising the arrangement of the component parts, a great effect that the coin hopper device can be miniaturized can be obtained.
That is, according to the present invention, there is a great effect that the height of the hopper device can be greatly reduced by arranging the electric motor upside down and arranging the gear train for reduction in the horizontal direction.

The present invention will be described below with reference to the accompanying drawings.
