BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin counter for counting many coins of the same kind, such as a game medal counter or a coin counter.

[0002]

2. Description of the Related Art As a conventional coin counter, there is, for example, a coin counter disclosed in Japanese Utility Model Publication No. 55-33413. This coin counting machine includes a hopper section capable of storing a large amount of coins, a rotating disk that receives coins supplied from the hopper section and sends out the coins in a single row by centrifugal force, and a coin fed from the rotating disk. A coin counting passage that counts while being conveyed, and when the coins stored in the hopper are manually supplied to the rotating disk by an appropriate amount, the coin is moved to the periphery by the centrifugal force of the rotating disk, and the coin counting passage. In a row, and counted by a ratchet wheel.

[0003]

In the conventional coin counting machine, if a large amount of coins are supplied on the rotating disk at one time, the coin cannot be fed out by centrifugal force. A hopper section for storing is required, which hinders downsizing and cost reduction of the machine, and also has a troublesome operation for supplying coins from the hopper section to the rotating disk.

In addition, since coins are sent out only in a single row from the rotating disk, the number of coins per unit time is limited even if the feeding speed is increased, and a high speed is required for counting a large number of coins. There was a problem that could not be handled.

The present invention has been made in view of the above points, and has as its object to provide a coin counter that is compact, inexpensive, and capable of high-speed processing.

The housing space 17 has left and right side surfaces on the inner wall 16 and side surface portions of the machine body 1. The front surface is constituted by an endless belt 18, and the rear and bottom surfaces are constituted by a hopper member 19.

The endless belt 18 is provided between the inner wall 16 of the body 1 and the side plate 15 at the front of the body 1, and a roller shaft 20,
The upper and lower rollers 22 and 23 rotatably mounted by 21 are rotatably extended in the up-down direction, and are formed to have a belt width substantially equal to the interval between the inner wall 16 and the side surface 15. I have. On the surface of the endless belt 18, a plurality of projections 34 whose projection height from the surface is lower than the thickness of the coin and whose interval in the rotational movement direction is at least larger than the diameter of the coin are projected over the entire belt width direction. .

An inner wall portion below the hopper member 19
A motor 35 as a driving means of the endless belt 18 is attached to the inner surface of the belt 16, and a pulley 37 is attached to a drive shaft 36 of the motor 35 between the side surface portion 14 and the inner wall portion 16, and a lower roller shaft Pulley 38 is attached to the end of 21 and both pulleys
A belt 39 is stretched between 37 and 38. And the motor
By driving the 35, the endless belt 18 is rotated so that the side facing the hopper member 19 moves upward.

The hopper member 19 is formed to have the same width as the inner width between the inner wall portion 16 and the side surface portion 15 of the fuselage 1, and is inclined downward from the rear portion 13 of the fuselage 1 toward the endless belt 18. A hopper bottom surface portion 40 is formed, and an arc surface portion 41 that gradually approaches the endless belt 18 with an arc-shaped surface is formed below the hopper bottom portion 40, and a steep continuous portion below the arc surface portion 41 is formed. An inclined surface portion 42 is formed which is inclined downward at an angle and faces the endless belt 18 at an interval corresponding to the thickness of one coin, and an arc-shaped surface portion is formed below the inclined surface portion 42 so as to form the discharge port 3. An emission surface 43 facing the lower edge is formed.

A rotating shaft 44 is rotatably mounted between the inner wall 16 and the side surface 15 of the machine body 1 on the back side of the inclined surface 42 facing the lower end of the endless belt 18. A plurality of metal reversing partition rollers 45 are fixed at intervals corresponding to the diameter of the coin over the entire area in the width direction, and a part of the outer peripheral portion of each of the reversing partition rollers 45 is formed on the inclined surface portion 42. A plurality of coin outlets 47 projecting from the reverse partition roller hole 46 and facing the surface of the endless belt 18 are provided for coins to be fed out one by one.

A rotating shaft 48 is rotatably mounted below the rotating shaft 44 between the inner wall 16 and the side surface 15 of the machine body 1 in parallel with the rotating shaft 44. A scraping roller 49 whose peripheral surface is made of urethane material is fixed between the reverse rotation section rollers 45, and a part of the outer peripheral portion of each scraping roller 49 is formed by the scraping formed on the inclined surface portion. It protrudes from the roller hole 50 to the lower center of the coin outlet 47.

Further, below the endless belt 18, between the inner wall 16 and the side surface 15 of the machine body 1, the surface of each of the scraping rollers 49 projecting from the inclined surface 42 has a thickness of one coin. Opposing leaf springs 51 are arranged at a small interval.

A large-diameter gear 52 is fixed to the roller shaft 21 between the side surface portion 14 and the inner wall portion 16.
A gear 53 meshing with the gear 53 is fixed to the rotating shaft 44, and a gear 54 meshing with the gear 53 is fixed to the rotating shaft 48. Therefore, when the endless belt 18 rotates, the reverse rotation section roller 45 reversely rotates in the direction opposite to the coin feeding direction, and the scraping roller 49 rotates in the coin feeding direction in the downward direction.

Each coin outlet 47 is provided with two pairs of photosensors 55 as counting sensors for counting coins sent from the coin outlet 47. The photo sensor 55 includes a light emitter 57 and a light receiver 58 that project and receive detection light through sensor holes 56 provided at both lower positions of the scraping roller hole 50, respectively.
The light receiver 58 is mounted on a support plate 59 that is installed between the inner wall 16 and the side surface 15 of the body 1. Then, the coin passing through the coin outlet 47 is
It counts when both the photo sensors 55 are shielded from light at the same time. The locations of the light projector 57 and the light receiver 58 may be reversed.

Next, the operation of the present embodiment will be described.

A coin to be counted is inserted into the accommodation space 17 through the insertion slot 2. The inserted coin is moved toward the endless belt 18 by the inclination of the hopper bottom portion 40 of the hopper member 19 due to its own weight.
A plurality of coins try to penetrate into a narrow place between the endless belt 18 and the endless belt 18 by the thickness of one coin while overlapping.

The endless belt 18 is moved by the drive of the motor 35 so that the side facing the hopper member 19 moves upward.
Rotates, the reverse rotation section roller 45 reversely rotates in the direction opposite to the direction in which the coin is fed downward, and the scraping roller 49 rotates in the forward direction in which the coin is fed downward.

For this reason, a plurality of coins try to enter in a narrow space between the inclined surface portion 42 of the hopper member 19 and the endless belt 18 by a thickness of one coin in a state of being overlapped.
Since the protrusions 34 formed on the surface of the scraper 18 sequentially scrape up the coins that are in contact with the endless belt 18 side, finally, only the coins that are in contact with the inclined surface 42 of the hopper member 19 are brought into a further state.

At the lower end position of the endless belt 18, the reverse rotation roller 45 for partitioning the coins outlet 47 in the width direction is opposed to the endless belt 18. The coins are divided into a plurality of rows corresponding to the coin outlets 47, and each coin outlet 47 falls under its own weight.

Then, counting is performed when two coin sensors, which are provided at each coin outlet 47, are simultaneously shielded from light by coins falling at their own coin outlets 47 under their own weight. Therefore, the number of coins passing through each of the plurality of coin outlets 47 is counted simultaneously, and high-speed processing can be performed as a whole.

[0027]

According to the present invention, the storage space for coins is formed by the endless belt and the hopper member, and the coins stored in the hopper member along the inclination of the bottom of the hopper member by their own weight. The coins between the endless belt and the endless belt are trying to penetrate the coins in a narrow space of the thickness of one coin, but the protrusions formed on the surface of the endless belt It is sequentially scraped up and finally brought into a further state. At the lower end position of the endless belt, since a reverse partition roller that forms a coin outlet in the width direction is opposed to the endless belt surface, a plurality of coins in a further state correspond to the coin outlet. It becomes a line and falls under its own weight. Then, the number of sheets passing through each row is counted simultaneously by a counting sensor provided at each coin outlet. Therefore, it is possible to provide a coin counter that is compact and inexpensive and that can perform high-speed processing as a whole.
