[0001]

[Industrial applications]

 According to the present invention, a plurality of coins stored in a hopper (including coins and similar articles are referred to as coins) are paid out one by one by rotation of a rotary disc that is inclined at a predetermined angle with respect to the horizontal direction. , A so-called inclined disc type coin feeding device.

[0002]

[Prior art]

 Conventionally, a structure described in, for example, Japanese Utility Model Laid-Open No. 60-104969 is known as an inclined disk type coin feeding device.

As shown in FIG. 4, for example, such a coin feeding device is provided with a rotary disc 1 which is rotated in a state of being inclined at a predetermined angle with respect to the horizontal direction, and the rotary disc 1 is provided on the front surface side thereof. A hopper 2 for storing coins is provided. A plurality of pins 3 are concentrically projected on the surface of the rotating disk 1. The protruding height of this pin 3 from the surface of the rotating disk 1 is less than the thickness of one coin, and the pin 3 The interval is set so that only one coin fits in the radial direction.

As the rotating disc 1 rotates, the stored coins in the hopper 2 are fitted one by one between the adjacent pins 3 in the lower region of the rotating disc 1 so that the upper part of the rotating disc 1 is covered. As well as picking up to the area, they are paid out one by one from the upper area of the rotating disk 1 to the coin passage.

The hopper 2 is provided with a control portion 4 that faces the periphery of the rotary disc 1 in parallel with a narrow space therebetween. The control portion 4 rotates toward the control portion 4 at the center of the control portion 4. An inclined portion 5 is formed so that the distance from the disc 1 is gradually narrowed. The regulation portion 4 ensures that the coins are scraped up by the pins 3 by placing the coins in the standing posture, and therefore the inclined portion 5 is formed to increase the storage amount of coins without remaining.

[0006]

[Problems to be solved by the device]

 However, in the conventional coin feeding device, as shown in FIG. 4, the edge portion of the coin C may be supported by the inclined portion 5 of the hopper 2 and the rotating disc 1. In such a state, even if the rotary disc 1 is rotated, the coin C cannot be paid out by only rotating on the spot, and the coin C remains. Moreover, if the coin C is rotated for a long time, the posture of the coin C may be pushed out by the momentum, but the efficiency is considerably deteriorated.

Further, not only when the above-mentioned state is caused, but to efficiently pay out coins, it is effective to stir the stored coins in the hopper 2. Therefore, I considered a plan to install a stirring member on the rotating disk 1, but there is a possibility that a coin may be caught between the stirring member and the hopper 2.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a coin feeding device that can feed coins efficiently without leaving the coins and that does not easily cause biting.

[0009]

[Means for Solving the Problems]

 The present invention comprises a rotating disk 11 attached to a rotating shaft 12 and rotated at a position inclined at a predetermined angle with respect to the horizontal direction, and a hopper 61 for storing coins on the surface side of the rotating disk 11. In a coin feeding device for picking up stored coins one by one by a plurality of pick-up members 17 protruding from the surface of the rotating disc 11, a plate member 21 rotatably mounted on the rotating disc 11, An agitating member 23 provided upright on the plate member 21 and a friction generating means 31 for generating a predetermined frictional force between the plate member 21 and the rotary disk 11 are provided.

[0010]

[Action]

 In the present invention, when the rotary disc 11 is rotated, the pick-up member 17 picks up the stored coins in the hopper 61 one by one. Normally (when no bite occurs), the plate material 21 is rotated by the rotating disc 11 due to the frictional force generated by the friction generating means 31, and the stirring member 23 scratches the stored coins in the hopper 61. mix.

Further, when a coin is about to be caught between the stirring member 23 and the hopper 61, slippage occurs between the rotating disc 11 and the plate member 21 and the plate member 21 moves before the coin is firmly caught. The rotation stops. Therefore, only the rotating disk 11 rotates, but the rotation of the rotating disk 11 moves the biting coin to release the biting.

[0012]

【Example】

 Hereinafter, a configuration of an embodiment of the present invention will be described with reference to FIGS.

In the figure, reference numeral 11 denotes a rotating disc. The rotating disc 11 is attached to a rotary shaft 12 in a state of being slightly inclined with respect to the horizontal direction, and is driven by a drive mechanism (not shown) for rotationally driving the rotary shaft 12. When the coin is fed out, it is normally rotated in the clockwise direction in FIG. 1 (the direction of the arrow in FIG. 1), and when the jam of coins on the rotating disk 11 is cleared, it is rotated in the counterclockwise direction in FIG.

A mounting hole 13 to be mounted on the rotating shaft is formed in the center of the rotating disc 11, and a fitting recess having a width wider than the diameter of the maximum diameter coin is formed between the mounting hole 13 and a peripheral portion of a plate member 21 described later at the peripheral portion. 14 are formed. On the peripheral edge of the rotating disk 11 facing the fitting recess 14, a plurality of long holes 15 extending in the rotation direction are concentrically formed so as to penetrate therethrough, and the distance between the long holes 15 is the maximum to be processed. The size is wider than the diameter of coins.

A leaf spring 16 is attached to the rear surface side of the rotary disc 11 at the edge of each elongated hole 15 on the rotation direction side, and the front surface of the rotary disc 11 is inserted through the elongated hole 15 at the tip side of the leaf spring 16. A pin 17 as a pick-up member protruding from is attached. The pin 17 is located at a position closer to the rotation direction of the elongated hole 15 and normally protrudes from the upper surface of the rotating disc 11 by a predetermined amount (a little smaller than the thickness of the minimum thickness coin). When a force or a force in the direction opposite to the rotation of the rotating disk 11 (upward or leftward in FIG. 3) is applied from above in the axial direction of the rotating disk 11, it retracts to the back surface side of the rotating disk 11.

On the surface of the rotating disc 11, a disc-shaped plate member 21 having a smaller diameter than the rotating disc 11 is attached. A fitting hole 22 that rotatably fits to the rotary shaft 12 is formed in the center of the plate material 21, and a fitting recess 14 is formed between the plate material 21 and the surface of the rotating disk 11 at the peripheral edge. A plurality of frustoconical stirring members 23 are provided upright near the peripheral edge of the surface of the plate member 21.

A predetermined frictional force is generated between the plate material 21 and the rotating disk 11 by the friction generating means 31. In the friction generating means 31, a cap 32 is fixed to the tip of the rotating disk 11 with a screw 33, and a spring 34 is arranged inside the cap 32. Therefore, due to the elasticity of the spring 34, the plate member 21 is pressed against the rotating disc 11, and unless otherwise particularly loaded, the plate member 21 rotates due to the frictional force with the rotating disc 11 as the rotating disc 11 rotates. To do.

A coin passage 41 that receives and conveys coins fed from the rotary disc 11 is formed obliquely upward from the upper position of the rotary disc 11. In this coin passage 41, a passage plate 42 that guides the lower surface of the coin is arranged in the same inclined state as the rotating disc 11, and the lower edge of the coin is arranged along the lower edge of the passage plate 42. A lower edge guide 43 for guiding is arranged, and further, an endless conveyor belt 44 for supporting the upper surface of the coin and giving a conveying force is arranged along the upper side of the passage plate 42.

In addition, the coin passage 41 is provided with an introducing portion 45 at the end facing the rotating disc 11 for receiving coins fed from the rotating disc 11, and a coin for conveying coins continuously to the introducing portion 45. The part 46 is formed.

In the introduction portion 45 of the coin passage 41, an introduction surface portion 47 is formed at the tip of the passage plate 42 on the same surface as the surface of the rotating disc 11, and the distance from the introduction surface portion 47 to the conveyor belt 44 is gradually increased. The inclined surface portion 48 is formed so as to be narrowed, and the inclined surface portion 48 is continuously formed on the conveyance surface portion 49 of the conveyance portion 46. Further, the lower edge guide 43 facing the introducing portion 45 is connected with a discharging member 50 that takes in the coins picked up by the rotating disc 11 into the coin passage 41, and the discharging member 50 includes the rotating disc 11. A passage groove 51 is formed on the surface of the fitting recess 14 at a distance such that coins cannot pass therethrough and through which the pin 17 passes.

The conveying section 46 of the coin passage 41 is provided with a discriminating section 52 formed of a material sensor, an image sensor, etc. for discriminating the suitability, suitability, and denomination of the coins to be conveyed. .

The conveyor belt 44 of the coin passage 41 is provided with a plurality of protrusions 53 along the side facing the passage plate 42 at intervals wider than the straight diameter of the coin having the maximum diameter, and faces the rotating disc 11. Is stretched between the pulley 54 and the other pulleys (not shown). Then, the conveyor belt 44 is rotatably rotated with the rotary disk 11 by a drive mechanism that rotates the rotary disk 11, and if the rotary disk 11 rotates clockwise in FIG. The belt 44 rotates counterclockwise and conveys coins in the coin passage 41. However, when the rotating disk 11 rotates counterclockwise, the conveyor belt 44 does not rotate. The coin transport speed by the transport belt 44 is slightly higher than the payout speed of the coins dispensed by the rotary disc 11.

Then, in the introduction section 45, a space t1 slightly wider than the thickness of the maximum thickness coin is provided between the conveyor belt 44 and the surface of the rotary disc 11, and the protrusion 53 and the surface of the rotary disc 11 are separated from each other. A space t2 narrower than the thickness of the minimum thickness coin is provided therebetween. Further, a space t3 (similar to the space t1) slightly wider than the thickness of the maximum thickness coin is provided between the conveyor belt 44 and the introduction surface portion 47, and the minimum thickness coin is provided between the conveyor belt 44 and the transportation surface portion 49. The spacing t4 is slightly narrower than the thickness of the.

A hopper 61 for storing coins is arranged on the surface side of the rotating disk 11 so as to cover the surface side of the rotating disk 11 and to store coins with the rotating disk 11. The hopper 61 has a bowl shape with an upper opening, and forms a storage space 62 between the hopper 61 and the surface of the rotating disk 11. A guide portion 63 is formed on the hopper 61 along the outer peripheral edge of the rotating disc 11, and a restricting portion that faces the peripheral portion of the rotating disc 11 from the guide portion 63 in parallel with a narrow space therebetween. 64 is formed, an inclined portion 65 is formed from the center side of the restricting portion 64 so that the distance from the rotating disk 11 gradually increases, and the wall surface is substantially vertical from the center side of the inclined portion 65. A vertical portion 66 is formed.

Next, the operation of this embodiment will be described.

When a plurality of coins are inserted into the storage space 62 surrounded by the rotating disc 11 and the hopper 61 and the rotating disc 11 is rotated, the outer peripheral edge of the rotating disc 11 is moved along the regulating portion 64 of the hopper 61. The coins that are in the standing posture in the section are fitted between the pins 17 in the fitting recess 14 and picked up one by one.

The coin picked up to the top of the rotary disc 11 moves along the ejection member 50 while being pushed by the pin 17, and is continuously pushed by the protrusion 53 of the conveyor belt 44 to pass the coin passage 41. Be delivered to.

The coins fed into the coin passage 41 are securely held by the passage plate 42 and the conveyor belt 24 because the coin passage 41 has a narrow thickness interval at the inclined surface portion 48, and is accurately identified by the identifying portion 32. It After that, processing such as classification is performed.

The pin 17 that has finished transferring coins passes through the passage groove 51 provided in the ejection member 50, and the next picking operation is performed.

By repeating such an operation, the stored coins are delivered to the coin passage 41 one by one.

Further, since the plate member 21 is pressed against the rotating disk 11 by the spring bias to generate a frictional force, when the rotating disk 11 rotates, it rotates accordingly. Therefore, the agitating member 23 provided upright on the plate member 21 rotates in the storage space 62 to agitate the stored coins, and the coins do not fall into the restriction portion 64 of the hopper 61, for example, the inclined portion 65 and the like are idle. Even if the condition is reached, it can be efficiently fed because it is immediately stirred and released.

Further, when a coin tries to be caught between the stirring member 23 and the inner surface of the hopper 61, a counterclockwise force in FIG. 1 is applied to the stirring member 23, so that the plate member 21 and the rotating disc 11 are separated from each other. There is slippage between them. When the plate 21 is fixed and only the rotating disk 11 rotates, the state of the surrounding coins changes, and the attitude of the bitten coins also changes. Although it is impossible to release the bite even if the force of is applied, it will be released with the force that the coins around move in the initial stage of biting.

When a coin is attempted to be caught between the pin 17 and the inner surface of the hopper 61 or between the pin 61 and the ejection member 50, the pin 17 is buried in the back surface side of the rotating disc 11, so that the pin 17 is caught. Is removed.

In the above embodiment, the plate member 21 is formed in a disc shape, but the present invention is not limited to this and may be, for example, a star shape.

[0035]

[Effect of device]

 According to the present invention, the agitating member provided upright from a plate member that rotates together with the rotating disc can stir the stored coins in the hopper, and all the coins can be fed out without remaining, and the coins can be efficiently delivered. You can get out. Furthermore, when a coin is likely to be caught between the stirring member and the hopper, slippage occurs between the rotating disc and the plate material, and the plate material stops rotating before the coin is firmly caught, so rotation continues. By the rotating disc that is rotating, the biting coin moves and the biting can be released, and the biting of the coin can be prevented.
