Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coin dispensing device used in currency exchange machines, vending machines, game machines, etc. This relates to a device that scoops up and dispenses one sheet at a time.

[Prior art]

A coin dispensing device with a rotating plate (disc) arranged at an angle and scooping up a large number of stored coins one by one is called a "hopper" and is used in currency exchange machines, vending machines, and game machines. It is incorporated into etc. A conventional coin dispensing device (hereinafter referred to as a hopper) has a disc-shaped protrusion in the center with a height that is approximately the same as the thickness of the coin.
A flat rotary plate with a plurality of claws formed in a predetermined pinch on the periphery is used, and this plate is installed at an angle.

Further, a scraper whose tip is in contact with the protrusion is disposed at or past the top of the rotary plate, and a chute having a rectangular passage slightly larger than the thickness of the coin behind the scraper. There is.

When throwing out a coin, the motor rotates the rotary plate at a predetermined speed, and the protrusion and the claw hold and scoop up the coin leaning against the rotary plate.

The coins scooped up by this rotary plate are separated from the rotary plate by a scraper and thrown into the chute.

The rotating plate becomes more horizontal and the smaller its inclination, the easier it is for coins to land on it. However, since multiple coins are thrown out in a piled state, coins often get stuck at the entrance of the chute. This is especially noticeable when the rotating plate is rotated at high speed. On the other hand, if you increase the inclination of the rotary plate so that it approaches verticality, you can eliminate the overlap of coins, but on the other hand, it becomes difficult to scoop up coins, and coins cannot be scooped up continuously. This causes problems such as so-called "breathing" and coins remaining without being scooped up by the rotating plate. The conventional rotating plate is
Many models set the inclination to around 60 degrees, but with a flat rotating plate, the inclination is the same at all positions, so
The above two contradictory demands could not be fully satisfied. Also, it is desirable to place the chute vertically in order to reduce friction and facilitate the transfer of coins, and from the relationship with the coin elevator, but this creates an angular difference between the chute and the rotary plate. There is also the problem that it is difficult to enter the chute.

(Objective of the Invention) The present invention provides a hopper that makes it easy to scoop up coins and remove them from the rotary plate, thereby preventing coins from clogging at the entrance of the chute, causing problems such as suffocation and remaining coins. The purpose is to

[Structure of the invention]

In order to achieve the above object, the present invention is characterized in that the inner surface around the bancho rotary plate is inclined inward to form a dish shape.

[Configuration of the first embodiment] In FIGS. 1 to 3, an L-shaped mounting plate 2 is fixed to the board 1;
It is tilted at approximately 60 degrees.

For this installation, a cylindrical morph holder 3 is attached to the back of the plate 2.
is fixed, and the motor 4 is fixed to this.

The rotating shaft 4a of this motor 4 is mounted through a hole 2a formed in the plate 2, and a rotating plate 6 is fixed to the tip thereof. As shown in detail in FIG. 3, this rotary plate 6 has a dish-like shape with an inner surface 60a of a peripheral portion 6o inclined inward by an angle θl. This angle θ1 is preferably 20 degrees, and since the entire body is inclined at 60 degrees, the angle is 40 degrees below the rotating plate 6 and 8 degrees above. Therefore, since the slope is gentle at the coin 7a position, it is easier to scoop up the coin, and at the coin 7c position, the slope is steeper, making it easier to separate from the rotary plate 6 and throw the coin into the vertically arranged chute 8. It becomes easier to do.

A plurality of pins 1o are provided on the inclined surface 60a of the rotary plate 6 at intervals somewhat wider than the diameter of the coin. The height of these pins 10 should be the same as the thickness of the coin, or
It's lower than that. In the center of the rotary plate 6, a first protrusion 61 is formed in the shape of a flange with a flat front surface and has a height that is approximately the same as the thickness of the coin in order to guide only one coin. There is. A second protrusion 62 having a diameter slightly smaller than this first protrusion 61 is placed on top of the first protrusion 61.
is formed. Furthermore, a conical stirring protrusion 63 is formed around the second protrusion 62 .

A cylinder 12 is fixed to the plate 2 so as to surround the rotating plate 6. This cylinder 12 has a notch at the top, and a scraper 13 is inserted into which notch 12a.

Further, a tapered surface 12b inclined by an angle θl is formed on the inner surface of the tube 12, and the edge of the coin can be held on this tapered surface 12b.

The coin storage section 15 includes a cylinder part 15a, a cover part 15b, and a bracket 15c.
C is fixed to the edge of the cylinder 12. This cylindrical portion 15a has
A money exchange machine has a large number of coins stored in it in advance.
In vending machines, coins inserted through the coin slot are refilled into the machine.

The scraper 13 is attached to a bracket 17 fixed to the plate 2, and has a sharp tip like a claw. This pointed tip is arranged so as to be in contact with the shoulder of the first protrusion 61 . Further, the scraper 13 has a flat top surface 13a, on which a coin can be placed. Note 1. This upper surface 13a is formed with a notch 13b through which a pin 0 provided on the rotary plate 6 is inserted. In this embodiment, the scraper 13 is arranged so that its tip is on the vertical line of the rotary plate 6.
The coin may be placed in a position past this vertical line and come out from below.

The entrance 8a of the chute 8 is located so as to be continuous with the upper surface 13a of the scraper 13. This shoot 8 is
A rectangular passage is formed inside, and is slightly larger than the thickness of the coin to prevent two coins from overlapping in the passage. Also, shoot 8
The wall 8b located on the back side of the coin is extended beyond the entrance 8a to prevent the coins taken out by the scraper 13 from falling behind the rotary plate 6. Also, this wall 8b
The tip is bent backward and fixed to the plate 2 with screws 20.

The counter plate 22 is rotatably supported by a shaft 23, and a roller 24 is attached to the tip thereof. When this counter plate 22 is pushed up by the edge of a coin, a pin 25 planted at the other end turns on a microswitch 26. Then, when the center of the coin passes through the center of the roller 24, the counter plate 22 is quickly returned by the spring 27, so that the coin is bounced toward the entrance 8a of the chute 8.

[Operation of the first embodiment] Next, the operation of the embodiment having the above configuration will be explained.

When power is supplied to the motor 4, the rotating shaft 4a of the motor 4 rotates at a predetermined speed, for example, 24/min, and drives the rotating plate 6.

A large number of coins are stored in the coin accommodating portion 15, and a gravitational force toward rotation @6 acts on these coins, and the coins are stirred by the stirring protrusion 63, so that the coins do not rotate. It comes to rest on the inclined surface 60a of the plate 6.

In this case, since the rotating plate 6 has a dish shape with the inclined surface 60a, the inclination becomes gentle below the rotating plate 6, for example, at the position where the coin 7a is, and the coin is held stable on the inclined surface 60a of the rotating plate 6. It can be kept.

The coin held on the rotary plate 6 is hooked by a pin 10 and scooped upward while contacting the tapered surface 12b of the cylinder 12. When the coin passes the horizontal center line of the cylinder 12, it moves toward the center of the rotary plate 6 due to gravity, and the edge of the coin contacts the shoulder of the first protrusion 61, and then rides on this shoulder. It turns out. In this case, the coin is held by the first protrusion 61 and the pin 10 so that it does not fall. When the coin rotates together with the rotating plate 6 and reaches the highest position, the tip of the scraper 13 is placed in contact with or close to the first protrusion 61.
ride on.

Since the rotary plate 6 is plate-shaped, the inclination gradually becomes steeper as it goes upward, and the inclination becomes the steepest at the position where it rests on the scraper 13. Therefore, since the coin stands up, it becomes easier to enter the chute 8 which is disposed almost vertically, and it also becomes easier to leave the rotary plate 6.

The coin that has landed on the scraper 13 is further pushed by the pin IO, and therefore moves while being guided by the scraper 13. When the coin moves on this scraper 13, it hits the roller 24, so the counter plate 22 is rotated clockwise against the spring 27. As a result, the microswitch 26 is turned on by the bottle 25 provided at one end of the counter plate 22. The ON signal of this microswitch 26 is a counting device such as a microcomputer (not shown).
sent to. When this counting device counts a predetermined number of coins, it short-circuits the motor 4 to stop it suddenly.

When the center of the coin passes the center of the roller 24, the spring 27 quickly returns counterclockwise to the position where the counter plate 22 collides with the protrusion 28, so that the coin is bounced toward the entrance 8a of the chute 8. blown away. Since this chute 8 stands almost perpendicular to the substrate 1,
The upright coin can be smoothly received without colliding with the entrance 8a, and since there is little frictional force due to the leaning of the coin, it can be smoothly transferred inside the chute 8. Since the chute 8 is formed with a passage wide enough to pass one coin,
The passageway will not be clogged due to overlapping coins. Said chute 8
The coins that enter the coin roll in a downwardly inclined passageway and are sent to a coin outlet or a vertically arranged coin elevator.

When a large amount of coins are stored in the coin storage section 15 or when the rotary plate 6 rotates at high speed, two coins may be scooped up while being overlapped by the rotary plate 6. In this case, the coin in front, for example, 7e, stands up as it moves upwards, so it falls due to vibrations caused by the coin's agitation, etc.; if the coin does not fall even after this, its edge will come off the first protrusion 61. Since the scraper 13t is in contact with the outer periphery of the second protrusion 62, the scraper 13t does not ride on it. Since the rotating plate 6 is plate-shaped, a gap is formed between the coin 7e and the coin below, making it easy to peel off the coin 7e with the scraper 13. And this coin 7e
is guided by the ridgeline 13c of the scraper 13 and falls below it. The coin that has fallen to the lower side is held by the empty pin 10, as in the case of coin 7d, for example.
It is scooped up again.

Even when the number of coins in the coin accommodating portion 15 becomes low, since the rotating plate 6 is shaped like a plate, the coins can be stored in the rotating plate 6.
It becomes easier to lean on. In addition, since the coins leaning against the cover part 1' 5 b of the coin accommodating portion 15 are pushed by the stirring protrusion 6d, the coins change their direction and lean against the rotary plate 6, so that no coins are left behind. The rotary plate 6 can scoop up the food without fail.

In the embodiment described above, since the periphery 60 is inclined at the same angle, the coin is fIJ! It is in contact with the lower part of the slope 60a, and the upper part is separated from the rotary plate 6 to form a gap. Moreover, since the coin stands up as it approaches the scraper 13, the coin tends to fall down due to vibrations etc. when stirring the coin. This is because by making the slope a curved surface or by making the slope multi-level, for example, two levels, the rotating plate can support not only the bottom of the coin but also the top, making the coin stable. This can prevent the rotor from falling from the rotary plate due to vibration or the like.

[Second example] FIG. 4 shows an embodiment in which the inclined surface is formed in two stages.

The rotating plate 40 has two inclined surfaces 41a on the inner surface of the peripheral portion 41.
, 41b are formed. The slope of the slope 41a is θ2, and the slope of the slope 41b is θ3 (θ2<θ3)
It is. In this example, θ2 is set to 12 degrees, and θ3 is set to 20 degrees.

The rotary plate 6.40 is not only cut with a lathe etc., but also
It can be made by drawing. If this drawing process is applied,
The strength of the rotating plates 6, 40 can be increased.

〔Effect of the invention〕

In the present invention having the above configuration, since the rotary plate is shaped like a plate,
At the position where the coin is scooped up, the peripheral part springs up, making it easier to scoop up the coin, and at the position where the coin is thrown, the peripheral part stands up, making it easier for the coin to separate, especially when the chute is placed vertically. In some cases, it can be poured smoothly without hitting the entrance. In addition, even if coins are scooped up in a stacked state, the coins will stand up, making it easier for the coins on top to fall off, preventing coins from being thrown out towards the sheet with the coins stacked in a stack. can do. Furthermore, since the rotating plate is plate-shaped,
Since the coin and the rotating plate do not come into close contact with each other, even if the coin is dirty or has water or sweat on it, it can be easily separated with a scraper. In addition, when the second protrusion is formed, if coins overlap, the coin on the upper side will be guided by the second protrusion and go around the second protrusion, so the coin will be thrown out and empty. There is also an additional effect, such as making it easier to get caught on the protrusions.
