Abstract

PURPOSE: To selectively add a counting batch function and a counting stoppage function at the time of errors such as the time of false coin detection or the like by providing a coin detection sensor at a position near the end of a coin path and providing a stopper at the end position of the coin path at the down stream side from the detection sensor installation area. CONSTITUTION: Coins moving along the reference path wall part 54 on the side of a rotary disk 11 of the coin, path 51 pass through a detection sensor 71 immediately before detaching from the lower side of a pressurization member 62. The detection sensor 71 detects the send-out of one coin by detecting detection light at the time of the passing of the coin and discriminates the denomination of the coin by the light shielding time of the detection light. Also, at the time of counting a prescribed number and at the time of the error of detecting false coins or the like, the passing of the coins from the coin path 51 is stopped by the stopper 91. Thus, the counting batch function and the counting stoppage function at the time of the error such as the time of the false coin detection or the like are added as needed.

The pressing member 62 is made of an elastically deformable material such as a sponge material, and when a coin has not entered, a gap smaller than the thickness of the processed coin is maintained between the rotating disk 11 and the coin, and the coin has entered. At that time, the coin is elastically deformed to press the coin against the upper surface of the rotating disk 11.

Further, the rotating disk 11 near the end of the coin passage 51.
A detection sensor 71 for detecting coins sent out along the reference passage wall portion 54 is provided at a slightly outer position. The detection sensor 71 is composed of a light emitting and receiving type optical sensor, a light emitting device 72 is attached to the base plate 32, a light receiving device 74 is attached to a supporting member 73 supported below the coin passage 51, and the light emitting device 72 and the light receiving device 74 are attached. The detection light is projected and received between and. And
The detection sensor 71 detects the delivery of one coin by blocking the detection light when the coin passes, and also determines the denomination of the coin because the blocking time of the detection light corresponds to the diameter of the coin. .

A coin discharge port 81 communicating with the outside of the apparatus is formed below the outlet portion 53 of the coin passage 51.
A coin discharge port member 82 is arranged around 81. The coin discharge port member 82 is frame-shaped and is attached to the outer frame 1.

When 91 is raised, the stopper plate portion 92 is above the height position of the outlet portion 53 of the coin passage 51, and coins discharged from the outlet portion 53 of the coin passage 51 can fall into the coin outlet 81. Has become. When the stopper 91 is lowered by turning on the solenoid 93, the stopper plate portion 92 is located at the height position of the outlet portion 53 of the coin passage 51, and the coin to be discharged from the outlet portion 53 of the coin passage 51 comes into contact with the stopper plate portion 92. Put the coin in the coin passage 51
It is supposed to stop inside.

Next, the operation of this embodiment will be described.

A coin is loaded into the coin storage space 41 of the coin storage hopper 31 from above, and the rotary disc 11 is rotated by the drive of the drive motor 21.

At this time, as shown in FIG. 5, when the amount of coins inserted into the coin storage space 41 is large, the peripheral wall member 42 is used.
Since some coins are placed on the inclined wall portion 45 to support the weight of coins, the load on the rotating disk 11 can be reduced. In addition, FIG.
As shown in, when the amount of coins inserted into the coin storage space portion 41 is small, the coins directly inserted from above onto the rotating disk 11 bounce to cause a coin standing, and the standing coins are inclined wall portions 45. When the coin is loaded onto the sloped wall portion 45 (shown on the left side of FIG. 6), the coin falls down on the way to the upper end of the sloped wall portion 45 (shown on the right side of FIG. 6). The coin that has fallen in contact with the second restricting portion 46 and has fallen down slides on the rotating disk 11 due to the inclination of the inclined wall portion 45.

Further, even if the coin is rotated and moved along the inclined wall portion 45 by the rotation of the rotating disk 11 or the coin is moved while leaning against the inclined wall portion 45, the coin is attached to the inclined wall portion 45. When the coin that rotates is brought into contact with the guide protrusion 47 that is formed, the coin can be forcibly dropped onto the rotating disk 11.

Further, the projection 13 of the rotary disk 11 is eccentrically rotated and the plurality of delivery members 16 are rotated to rotate the coin storage space.
You can loosen the coins in 41.

The coins placed in surface contact on the rotating disk 11 move radially outward due to the centrifugal force generated by the rotation of the rotating disk 11, and some of the coins enter the entrance 52 of the coin passage 51. Entered directly, some coins are
The inlet portion 52 is in contact with the regulating portion 44, moves along the first regulating portion 44, and faces the inlet portion 52 of the coin passage 51.
Enter.

The coin that has entered the entrance 52 of the coin passage 51 is
It directly enters the lower side of the pressing member 62, or enters the lower side of the pressing member 62 through the guide portion 56 and the contact plate 59 of the opposing passage wall 55.

The coin that has entered below the pressing member 62 is shown in FIG.
And as shown in FIG. 8, the upper surface of the rotating disk 11 is pressed by the delivery body 15 having a high friction coefficient, and while the contact state with the rotating disk 11 is maintained, the rotational force is received from the rotating disk 11 to move together. To do. As the coin rotates and moves together with the rotating disk 11, the peripheral edge of the coin comes into contact with the reference passage wall portion 54 and moves together with the rotating disk 11 along with the reference passage wall portion 54.
Gradually move outward in the radial direction.

The coin moving along the reference passage wall portion 54 passes through the detection sensor 71 immediately before coming off from the lower side of the pressing member 62. The detection sensor 71 detects the sending of one coin by blocking the detection light when the coin passes, and as shown in FIG. 7, in the case of a small-diameter coin, the detection light is shielded for a short time.
As shown in (1), in the case of a large-diameter coin, the light-shielding time of the detection light is long, and the denomination of the coin is determined according to the light-shielding time of the detection light.

The coin removed from the lower side of the pressing member 62 is discharged from the outlet of the coin passage 51 by the centrifugal force generated by the rotation of the rotating disk 11.
It is discharged from the coin outlet 81 from 53 and falls out of the device. At this time, even if the coins burst out of the coin passage 51,
The coin hits the regulating edge portion 83 of the coin outlet member 82 and the inner wall surface of the outer frame 1 and falls downward.

Further, in the case of performing batch counting in which a predetermined number of coins are sent out, when the predetermined number of coins is detected by the detection sensor 71, the solenoid 93 is turned on and the stopper 91 is lowered, and the stopper 91 is moved. A predetermined number of coins next come into contact with the stopper plate portion 92 of the coin, and the coins pass through the coin passage 51.
Stop inside. At this time, even if the stopper 91 descends while the predetermined number of coins are being discharged, the stopper 91
The stopper plate portion 92 comes into contact with the upper surface of the predetermined number of coins being discharged, and the coins are forcibly dropped into the coin discharge port 81.

The solenoid 93 is also used when a counterfeit coin is detected by the detection sensor 71 or when a coin is not delivered along the reference coin passage wall 54.
Turns on and stops the coin. At this time, for example, when detecting a counterfeit coin or the like, if the detection time by the detection sensor 71 is early, the stopper 91 stops the counterfeit coin or the like, and if it is late, stops the next coin such as counterfeit coin. .

As described above, due to the construction of the peripheral wall member 42, even if a large amount of coins are thrown into the coin storage space 41, the load on the rotating disk 11 can be reduced, and even if a coin standing occurs, it can be surely tilted. The coin can be sent reliably. In particular, when the rotating disk 11 is downsized and the drive motor 21 is downsized, the configuration of the peripheral wall member 42 is particularly effective,
The rotating disk 11 and drive motor 21 can be downsized, and even if a large amount of coins are thrown in, reliable high-speed processing (high-speed processing when considering the diameter of the rotating disk 11 with a small diameter) Is possible. Moreover, since the stopper 91 is provided, a counting batch function and a counting stop function at the time of error such as detection of counterfeit coins can be selectively added according to demand.

Further, a coin storage hopper 31 is provided on the upper portion of the outer peripheral edge side of the rotary disc 11, and the rotary disc of the coin storage hopper 31 is rotated.
A coin passage 51 is formed on the surface facing 11 and coins entering the coin passage 51 are sent out along the reference passage wall portion 54 under the rotational force of the rotating disc 11, so that the coin passage 51 is formed by the rotating disc 11.
The structure is small along the circumferential direction, and the structure can be simplified without requiring special coin transfer means and drive means.

The facing passage wall portion 55 includes the guide plate 56 and the facing portion 57 as well as the contact plate 59. The contact plate 59 is attached to the outer frame 1 in the above-described embodiment, but this contact plate 59. A wall corresponding to the above may be provided on the coin storage hopper 31 side.

According to the coin dispenser of claim 1,
A coin storage hopper is provided on the upper part of the outer peripheral side of the rotating disc, and the coin passage is formed on the surface of the coin storing hopper that faces the rotating disc. The coin passage structure can be made simple and small. Moreover,
Since the stopper is provided, the counting batch function and the counting stop function at the time of error such as detection of counterfeit coins can be selectively added as desired.

According to the coin delivery device of the second aspect, in addition to the effect of the coin delivery device of the first aspect, the pressing member provided in the coin passage presses the coin against the rotary disc, so that the coin is rotated. Therefore, the coin can be reliably delivered along the reference passage wall portion.
