Description

The present invention relates to a rotating disk for feeding coins one by one from a hopper head. In particular, the present invention relates to an improvement of a rotating disk in which the rotating disk is surely taken into a through-hole in which the coin falls and the coin payout rate is improved.
Note that “coin” used in this specification includes coins as currency, substitute money such as medals and tokens of game machines, and the like.

As this type of dispensing device, those described in Japanese Patent Application Laid-Open Nos. 2001-14507 and 2000-306132 are known. In this type of apparatus, rotation of a rotating disk arranged at the bottom of the hopper head causes the coins stored in a stacked state in the hopper head to be agitated and rotated, and to a plurality of through holes formed in the peripheral part of the rotating disk. It is captured. The taken-in coins are forcibly moved on a guide plate arranged under the rotating disk by a feeding claw provided in the vicinity of the lower surface of the through hole in the rotating disk, and are sent out from an outlet at a predetermined location. It is configured.

JP 2000-306132 A Japanese Unexamined Patent Publication No. 2004-70680

In the conventional apparatus shown in the above publication, the rotating disk having a plurality of coin receiving holes in the circumferential direction is arranged at the outermost part of the through hole, that is, the outermost peripheral part of the disk opposite to the center of the disk. Has an arcuate bone (rib), although its width is small.
Even when the rotating disk is incorporated in the hopper head, the bone portion exists between the peripheral wall and the through hole of the rotating disk inside the cylindrical peripheral wall of the hopper.
Then, some of the coins agitated by the rotation of the rotating disk leaned against the inner surface of the peripheral wall of the hopper while standing on the bone part (edge part) of the small part existing up to the through hole. As a result, it does not easily enter the through hole.

In this case, the rate of coin drop into the through hole is deteriorated, so that the coin payout rate is lowered and the payout performance is inferior.
FIG. 7 is a diagram schematically showing the phenomenon of the problem. FIG. 8 is a plan view of the rotating disk before improvement which has the above problem. In FIG. 7, the rotating disk (4d) is rotatably arranged in a hopper head (18) formed in a cylindrical shape of the coin hopper (1). The rotating disk (4d) is set apart from the guide plate (5d) immediately below it by an interval (t) adjusted according to the thickness of the coin to be paid out.
Among the coins (C) that are stirred and rotated by the rotating disk (4d) in the hopper (1), as shown in FIG. 7, the coin (C) is the rotating disk (4d). At the outer peripheral edge, it rides on the bone part (15r) remaining on the outer edge of the through hole (8) and stands while leaning against the inner wall surface (18s) of the hopper head (18). For this reason, the standing coin (C) does not enter the through hole (8), and this phenomenon can occur frequently, so that the coin take-in rate is reduced and the payout performance is lowered.
In addition, the above-mentioned bone part (edge part) in the rotating disk (4) is a part indicated by a drawing number (15r) in the drawings showing the rotating disk in FIGS.

By the way, in order to solve this problem, the outer peripheral edge (15m) of the rotating disk including the bone part (15r) and the bone part (15r) of the rotating disk in the hopper head is the inner periphery of the hopper head. There is also a structure that does not remain on the surface side, that is, does not expose.
FIG. 9 shows the configuration of the example. In this case, a cylindrical hood (19) whose inner diameter matches the hopper head (18) and a ring-shaped space (21) are separately added as new components. Then, the spacer (21) is disposed on the guide plate (5d), and the hood (19) is disposed between the spacer (21) and the hopper head (18).
In the hood (19), the hopper head (18) can be concealed so that the bone portion (15r) and the outer peripheral edge portion (15m) of the rotating disk (4d) can be accommodated and concealed on the inner peripheral surface portion of the lower end portion thereof. A recess (22) having a diameter slightly larger than the inner diameter is formed in a circular shape.
By doing so, the inner peripheral surface (18s) of the hopper head (18), the inner peripheral surface (19s) of the hood (19), and the inner peripheral surface (8s) of the through hole (8) coincide with each other in the vertical direction. The bone portion (15r) of the through hole (8) of the rotating disk does not exist at the lower end of the inner peripheral surface (19s) of the hood (19), and the bone portion (15r) is a recessed portion of the hood. (22) It goes inside and hides, and it doesn't appear on the inner edge of the hopper.
Therefore, as shown in the figure, the coin (C) cannot get on the bone part (15r) of the through hole (8), and the coin (C) enters the through hole (8).

However, this type of structure requires many components such as a cylindrical hood (19) and a ring-shaped spacer (21), and is structurally complicated and expensive.
Also, when the type of coins to be paid out is changed, the distance between the rotating disk (4d) and the guide plate (5d) can be adjusted with another spacer (21) with a suitable height. Work and removal of the hood (19) are required, and there is a problem that the change work such as reassembly is complicated and inefficient.

On the other hand, since the coin hopper having the structure shown in FIG. 7 has a structure in which the rotating disk (4d) is inserted into the hopper head (18), the rotating disk (4d) is flush with the hopper head (18). It is possible to move up and down without difficulty inside the inner surface.
Therefore, in addition to the advantage that this type of coin hopper has a simple structure and is inexpensive, the rotating disk is adjusted with respect to the guide plate according to the change of the coin type. Since it is easy to install (adjusting the height of the rotating disk in accordance with the thickness of the coin), it is possible to respond immediately to the change of the payout coin.
However, on the other hand, the bone (15r) as described above remains on the outer peripheral side of the through hole (8) in the rotating disk (4d), so that the coin (C) stands on the bone (15r). There was a problem that the coins payout rate deteriorated.
The present invention has been made in view of this problem. In a coin hopper of a type suitable for changing this type of payout coin, the above-described coin does not rise on the outer peripheral edge of the rotating disk, and the coin passes through the hole. It is an object of the present invention to provide a coin hopper rotating disk which is improved so that it can be easily taken in and the payout performance is improved.

In order to achieve this object, the coin hopper rotating disk of the present invention has a hopper head installed on a base placed on the top of the hopper body, in which coins are held in a stacked state, and driven to rotate at the inner bottom of the hopper head. A rotating disk that is freely arranged and has a plurality of through holes through which coins fall circumferentially arranged at the periphery thereof, and a coin received in the through hole is used as a pushing projection when the rotating disk rotates. In the coin hopper provided with a guide plate disposed under the rotating disk so as to slide and guide to the coin outlet, the rotating disk has a slope portion for guiding and dropping the coin into the through hole of the rotating disk. It is formed upright on the outer peripheral edge.

According to a second aspect of the present invention, in the rotating disk of the coin hopper according to the first aspect, the inclined portion is connected to the outermost edge of the through hole so as to project around the rotating disk in a ring shape. The inner side is a protruding edge formed on a downwardly inclined surface.

According to this configuration, the coin in the hopper head is agitated by the rotation of the rotating disk and falls into the through hole.
The dropped coin is pushed by the pushing protrusion of the rotating disk.
In the case of the conventional rotating disk, the coin leans against the wall surface of the hopper head and sometimes stands at the edge (bone part) of the through hole. In the present invention, the edge of the through hole faces the through hole. Since there is a downward slope and there is no bone part where coins can ride, the coin cannot stand up at the edge of the through hole, and it will be guided and dropped to the through hole by the downward slope .
Therefore, the rate of falling of coins into the through-holes of the rotating disk is improved, the rotating disk can efficiently capture and pay out coins, and the coin processing by the hopper device is improved.
Even if the rotating disk has a structure with an inclined portion around the outer periphery of the through hole of the rotating disk, the rotating disk is a type of hopper head that is inserted into the hopper head, so there is nothing to move the rotating disk up and down in the hopper head. There is no hindrance, so it is possible to easily adjust the setting height of the rotating disk according to the type (thickness) of the coins to be paid out, so the type (thickness) of the coins to be paid out while maintaining a good coin capture rate. It can easily cope with the change and adjustment of the installation height of the rotating disk according to the above, and its practicality is high.

In addition, if a protruding edge is provided in a ring shape on the entire outer periphery (the entire periphery) of the rotating disk, and an inclined portion is provided with the inner surface of the protruding edge as an inclined surface, the coin can be located anywhere around the rotating disk. Since it is slid down toward the center of the rotating disk, the capture rate of the entire coin in the through hole is further improved, and the coin payout performance of the rotating disk is further improved.
The formation of the inclined portion can be obtained at the same time when the rotating disk is formed, and thus can be provided at a low cost.

A hopper head installed on a base placed at the top of the hopper main body, in which coins are held in a stacked state, and a plurality of through holes that are rotatably disposed on the inner bottom portion of the hopper head to allow coins to fall A rotating disk formed circumferentially around the periphery and a lower part of the rotating disk so that the coin received in the through hole is slidably guided to the coin outlet by the pushing protrusion when the rotating disk rotates. In a coin hopper provided with a guide plate arranged in
The rotating disk is a rotating disk for a coin hopper, characterized in that a slope portion for guiding and dropping a coin into the through hole is formed upright on the outer peripheral edge of the rotating disk.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a coin hopper in which the rotating disk of the embodiment is used. FIG. 2 is a perspective view of the rotating disk of the embodiment. FIG. 3 is a plan view of the rotating disk of the embodiment. FIG. 4 is a side sectional view of the rotating disk of the embodiment. FIG. 5 is a side cross-sectional view of the main part of the coin hopper showing the manner of taking in coins in the coin hopper with the rotating disk of the embodiment inserted therein. 6 is a partial cross-sectional view of a portion B in FIG.
Further, FIG. 7 is a side sectional view showing a coin hopper having a conventional structure together with a problem of coin standing. FIG. 8 is a plan view of a conventional rotating disk. FIG. 9 is a side sectional view showing a coin hopper of a type that solves the problem of coin standing due to the conventional structure.

1 to 6, etc., a coin hopper device 1 which is a coin delivery device includes a hopper head 2 that holds coins C in a stacked state, and a base 3 on which an upper surface for placing the hopper head 2 is inclined. The rotating disk 4 receives a coin 4 that is rotatably provided on the inner bottom of the hopper head 2 and a coin C that is disposed directly below the rotating disk 4 and is sent by the rotating disk 4. It includes a guide plate 5 for sliding and guiding to a delivery port provided at an appropriate position in the peripheral part.
In this case, the guide plate 5 is a rectangular base plate attached and fixed to the inclined upper surface of the base 3 with screws. A base plate which is a guide plate 5 is inclinedly installed on the upper surface of the base, and the hopper head 2 is mounted and fixed thereon via a rectangular bottom plate 6 provided at the lower end portion thereof. A saddle-shaped attachment hole 7 is provided at the four corners of the bottom plate 6 of the hopper head 2, and a screw (not shown) is inserted from the large-diameter hole portion of the daruma-shaped attachment hole 7 into the small-diameter hole portion. The hopper head 2 can be mounted and fixed by moving and screwing. Further, the hopper head 2 can be pulled out and removed by rotating in a direction in which the large diameter hole of the daruma-shaped mounting hole 7 matches the screw.

A plurality of through holes 8 for receiving circular coins are formed at equal intervals around the rotating disk 4, and the coins C in the hopper head 2 are rotated through the through holes 8. Along with this, it is supposed to be taken down. Although not shown, a protruding piece-shaped coin pushing portion for pushing the coin C forward when the rotating disk rotates is formed in the vicinity of the lower edge of the through hole 8 so as to protrude downward.
As the rotary disk 4 rotates, the coin C in the hopper head 2 is stirred and falls into the through hole 8. The fallen coin C is pushed by the above-described coin pushing portion while being held in the through hole 8, and is sent clockwise on the guide plate 5 in FIG. Sent to move to the middle upper zone. A coin outlet is provided in the vicinity of the upper area in the middle of the left side to which the coin C has moved. The coin outlet can be provided by notching a part of the peripheral surface of the cylindrical wall portion 2d extending downward so as to surround the rotating disk 4 in the hopper head 2 into a band-shaped rectangular opening.

Next, the structure of the rotating disk 4 that is a main part of the present invention will be described.
The rotating disk 4 has a circular main body part 11 having a predetermined thickness, and a boss part 12 that fits a driving shaft (not shown) for driving the rotating disk protrudes from the center of the circular main body part 11, The plurality of circular through holes 8 described above are formed at equal intervals around the boss portion 12 as a center.
Here, the rotating disk 4 has a protruding edge 14 integrally formed on the outer peripheral portion thereof so as to surround the whole in an annular shape. The inclined surface portion 13 is a downward inclined surface formed so as to decrease in diameter as it goes downward.
The outer surface 16 of the protruding edge 14 is a smooth outer surface 16h that stands vertically as shown in FIG.
Accordingly, as shown in FIGS. 2, 4, 6 and the like, the protruding edge 14 has a right-angled triangular cross section, is present in a ring shape on the outer peripheral edge of the rotating disk 4, and is a sloped portion 13 whose inner side is inclined. This is the protruding edge 14 of the structure.
Since the protruding edge is a slope portion, even if a coin that moves around the outer periphery by the rotation of the rotating disk comes near the slope portion, it does not get on the slope portion.
Rather, the inclined surface 13 that is the inclined surface of the protruding edge 14 acts as a sliding surface with respect to the coin C, and rotates the coin C that rotates in the circumferential direction around the outer periphery of the rotating disk 4 at the center of rotation of the rotating disk 4. It functions to slide toward you.
That is, the inclined portion 13 is in the vicinity of the outer peripheral portion of the rotating disk 4 and leans against the inner surface of the cylindrical wall portion 2d of the hopper head 2 so that the coin C immediately slides toward the center of the rotating disk 4 even if it tries to stand. Thus, it becomes a guide part that falls into the coin receiving hole 8.

As described above, the protruding edge 14 that protrudes all around the outer peripheral portion of the rotating disk 4 on the disk surface of the rotating disk 4 is partially arc-shaped when viewed from above as shown in FIG. Thus, the through hole 8 is positioned so as to overlap the outer peripheral edge of the rotating disk 4. That is, the inclined portion 13 is positioned on the outermost hole edge portion of the through hole 8.

In this way, on the surface of the rotating disk 4, the portion of the coin C so as not to leave the edge (rib) on the outer peripheral portion (outer edge) of the through hole 8 as shown in FIG. In addition, an inclined portion 13 that is annular and has a downwardly inclined surface on the inside is erected to eliminate the edge portion.

Therefore, when the coin C is positioned in the through hole 8 of the rotating disk 4 due to the presence of the projecting edge 14 having an inclined surface on the inside, the coin leans against the cylindrical wall portion 2d of the hopper as in the prior art. It becomes impossible to stand at the hole peripheral portion of the through hole 8, and it is surely slid down into the through hole 8 by the inclined inner surface of the protruding edge 14, that is, the inclined portion 13.

As a result, the capture rate at which the coin C is captured in the through hole 8 is increased, and the rotating disk pays out the coin C speedily, thereby improving the payout capability.
If the inclined portion 13, that is, the protruding edge 14 is provided on the outer peripheral portion of the rotating disk 4 so as to exist at least in the outermost peripheral portion of the through hole 8, the coin which has been a problem in the past is used. Standing can be suppressed.

However, as in the embodiment, the construction in which the entire circumference of the rotating disk 4 is erected so as to surround the entire outer circumference of the rotating disk 4 is less expensive than the production of the inclined portion 13, that is, the protruding edge 14. However, since it is inexpensive, easy to manufacture and advantageous, it is practical and preferable to form it all around.
In addition, if the protruding edge 14 is on the entire circumference of the rotating disk 4, even at a portion of the protruding edge 14 other than the through hole 8, that is, the protruding edge 14 positioned between the through hole 8 and the through hole 8 there. Since the coin C which has been moved to the position of the rotating disk 4 is moved from the outer peripheral side of the rotating disk 4 toward the inner center due to the inner surface inclination of the protruding edge 14, Therefore, it is more preferable that it is located all around because the probability of being dropped into the through-hole 8 becomes higher and a synergistic effect that promotes the capture of the coin C can be expected.

As described above, by providing the inclined portion 13 having the inclined surface with the inner side facing downward on the outer peripheral portion of the rotating disk 4, the bone portion (room portion) where the coin stands at the outer peripheral edge portion of the through hole 8 disappears. It is possible to prevent the coin from standing. Moreover, the means for that can also be achieved by a very simple correspondence by merely forming the protruding edge 14 having an inclined inner surface.
Therefore, according to this configuration, the coin C can continuously fall into the through hole 8 without interruption, the coin capture rate is increased, and a coin hopper rotating disk capable of stably and highly efficiently paying out coins can be obtained.
