[0002]

2. Description of the Related Art Conventionally, a coin dispensing apparatus of the inclined disk type has been disclosed in, for example, Japanese Patent Application Laid-Open No. 61-251989, in which a rotating circle is rotated at a predetermined angle with respect to the horizontal direction. A plate is provided, and a hopper for storing coins is provided on the surface side of the rotating disk. A plurality of pins protrude concentrically on the surface of the rotating disk, and the protruding height of the pins from the rotating disk surface is less than the thickness of one coin,
The distance between the pins is such that only one coin fits in the radial direction.

[0003] With the rotation of the rotating disk, the coins stored in the hopper are fitted one by one between adjacent pins in the lower region of the rotating disk and picked up in the upper region of the rotating disk. In the upper area of the rotating disk, the sheet is fed one by one from the rotating disk via the projecting piece.

[0004]

However, in the conventional coin feeding device, in the area where the pin enters the stored coin, the stored coin is pushed into the lower storage area by the pin, so that the coin is likely to be jammed. . In addition, not only in this area but also in other areas, coins may be jammed because the pins always protrude.

[0005] Further, when the pin enters the stored coin, a load is applied to the pin engaged with the stored coin in a direction opposite to the rotation, and the load easily causes deformation or breakage of the pin.

[0006] The present invention has been made in view of such a point, and the vicinity of the rotation position where the pickup member enters the stored coins.
Can prevent the occurrence of jammed coins
In both cases , it is an object of the present invention to provide a coin feeding device that can avoid suddenly applying a large load to the pick-up member .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a rotating disk, and the rotating disk 1 has a rotating shaft 2 which is slightly inclined with respect to the horizontal direction.
The driving force is transmitted to the rotating shaft 2 from a motor (not shown) or the like, and the rotating shaft 2 is driven to rotate in the direction of the arrow in FIG. A hopper 3 for storing coins between the rotating disk 1 and the rotating disk 1 is disposed on the surface of the rotating disk 1 so as to cover the surface of the rotating disk 1.

The rotating disk 1 has a first rotating disk 11 on the front side.
And a second rotating disk 11 located on the back side of the back side of the first rotating disk 11.
And each of the rotating disks 11 and 12 is attached to the rotating shaft 2.

The first rotary disk 11 has a mounting hole 13 formed at the center thereof for mounting on the rotary shaft 2 and a stepped portion formed on the peripheral edge of the surface.
A recess 15 having a width slightly larger than the diameter of one coin is formed through the recess 14. Opening 16 on concentric circle in recess 15
Are formed so that the interval between the openings 16 is slightly larger than the diameter of one coin.

The second rotating disk 12 is made of an elastic material,
A mounting hole 17 is formed in the center to be mounted on the rotating shaft 2,
A pin 18 is mounted on the surface as a pickup member to be inserted into each opening 16 of the first rotating disk 11. When the second rotating disk 12 is in the normal position, the pin 18 penetrates through the opening 16 of the first rotating disk 11 and projects by an amount slightly smaller than the thickness of one coin. It is supposed to. In addition, 19 is a notch.

Further, when coins are stored between the rotating disc 1 and the hopper 3 and the rotating disc 1 is rotated, the pin 18 enters the stored coins in the area a where the second rotating disc 1 is rotated. An urging roller 21 is provided as urging means for urging the rearward direction of the wheel 12. The urging roller 21 is attached by a support shaft 22 so as to be rotatable in the rotation direction of the second rotating disk 12. Then, in the area a, the second rotating disk 12 is displaced rearward by the urging roller 21, but in other areas, the second rotating disk 12 returns to the original normal position due to the elasticity of the second rotating disk 12. This second rotating disk 12
The displacement amount of the pin 18 is determined by the tip of the pin 18
Slightly retracted from the surface.

A projecting passage 31 extends obliquely upward above the first rotating disk 11. This outlet passage 31
Is formed by a passage member 32 which faces the periphery of the first rotating disk 11 and is substantially flush with the surface of the concave portion 15, and a guide piece for guiding coins to a lower edge portion of the passage member 32. Portion 33 is formed, and a concave portion is formed from the tip of the guide piece portion 33.
A projecting piece 34 protruding from the surface of the projection 15 is formed. The ejection piece 34 is opposed to the surface of the recess 15 at an interval at which coins cannot pass, and a passage groove 35 through which the pin 18 passes is formed.

On the discharge passage 31, a discharge belt 37 having a projection 36 is stretched by a plurality of pulleys 38. FIG.
As shown in the figure, a space slightly larger than the thickness of one coin is set between the ejection belt 37 and the passage surface of the ejection passage 31, and one coin is provided between the projection 36 and the passage surface. An interval smaller than the minute thickness is set. Then, by the rotation of the throw-out belt 37, the coins transferred to the throw-out pieces 34 are pushed by the projections 36 and moved in the throw-out passage 31.

The throw-out passage 31 communicates with the discriminating section and the like, and coins fed one by one are subjected to predetermined processing.

The hopper 3 has a guide portion 3a which is open upward and has a guide region 3a formed in a lower region thereof, which is substantially parallel to the surface of the first rotating disk 11 with a width smaller than the coin diameter. The part 3a functions so that the coin is set to the standing posture and falls on the surface of the first rotating disk 11.

Next, the operation of this embodiment will be described.

A plurality of coins are put into a space surrounded by the hopper 3 and the rotating disk 1, and the rotating disk 1 is rotated. With the rotation, in the area a where the pin 18 protrudes into the stored coins, the second rotating disk 12 is urged backward by the urging roller 21, so that the pin 18 is also moved to the first rotating disk. It is retracted from the surface of 11. For this reason, it is possible to avoid the coins, which tend to occur when the pins 18 enter the stored coins, and to prevent the pins 18 from being deformed or damaged.

When the pin 18 passes through the area a in which the coin enters the stored coin, the second rotating disk 12 elastically returns to the normal position, so that the pin 18 also projects from the surface of the first rotating disk 11. Come. The protruding pin 18 picks up one coin fitted into the recess 15. Since the protrusion amount of the pin 18 is less than the thickness of one coin at the maximum, only one coin can be reliably picked up.

The coin picked up to the upper area of the rotating disk 1 moves along the ejection piece 34 while being pushed by the pin 18, and then is pushed by the projection 36 of the ejection belt 37 to be ejected. It is fed out from the exit passage 31.

Further, the pin 18 after the coin has been delivered,
After passing through the passage groove 35 provided in the projecting piece 34, it is retracted again from the surface of the first rotating disk 11 in the area a.

By repeating such an operation, the stored coins are fed out one by one from the discharge passage 31.

Further, even if coins are caught in the area other than the area a, the pin is pushed into the first rotating disk 11 so that the coins are released. After the coin is released from being bitten,
The pin 18 is returned by the elasticity of the second rotating disk 12.
