[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc body throwing apparatus in which disc bodies such as a plurality of medals, coins, and tokens put into a hopper are thrown out one by one from the hopper. Regarding improvement of output device.

[0002]

2. Description of the Related Art Generally, discs such as coins, medals, and tokens are used in devices such as ticket vending machines, change dispensers for vending machines, currency exchange machines, coin counting machines used in banks, etc. A disc ejecting device for ejecting and ejecting one by one is arranged.

This disc ejecting device has a hopper that temporarily stores a plurality of discs such as coins that have been inserted, and a diameter of the disc that is rotatably supported by the bottom of the hopper. A disc-body ejecting disc (hereinafter, simply referred to as a disc) having a plurality of disc-conveying holes having a diameter slightly larger than that (hereinafter, simply referred to as a conveying hole) is concentrically formed at a plurality of positions.

When this disk is rotated by a disk drive means composed of a motor and a drive control section thereof, the disk bodies that are loaded into the hopper and temporarily accumulated are placed one by one in a posture substantially parallel to the disk. The disc is inserted into the transport hole, and is further ejected in the radial direction of the disc by the centrifugal force of the rotating disc, and is further ejected one by one from the disc ejection hole formed in the bottom of the hopper.

By the way, according to the above-mentioned conventional disc body ejecting device, as shown in FIG. 12 which is a partially broken sectional view of the concept and FIG. 13 which is an enlarged sectional view of the AA main part thereof, the disc body ejecting device is shown. A phenomenon in which a plurality of coin groups 4 of coins 3 inserted into the hopper 2 of the device 1 are inserted into and around all of the transport holes 6 in a posture in which the coins 3 stand vertically with respect to the disk 5 (so-called bridge phenomenon). ) May occur.

When such a bridging phenomenon occurs, even if the disc 5 rotates in the direction of arrow B shown in FIG. 13, the coins 3 constituting the coin group 4 are placed in the conveying hole 6 in a posture parallel to the disc 5. Since coins cannot be inserted one by one, one coin 3 cannot be dispensed from the disc body dispensing device 1.

In FIG. 12, reference numeral 7 is a hood that covers the upper edge of the hopper 2, 8 is a coin diffusion plate that distributes the inserted coins 3 into a wide range of the hopper 2, 9 is a coin payout opening, and 10 is a disk 5. A base plate supporting the lower surface, 11 is a motor constituting the disk drive means 12, and the driving force of the motor 11 is transmitted to the central shaft 5a of the disk 5 via a power transmission means such as a gear not shown. Further, in FIG. 12, reference numeral 13 is a support frame which supports the hopper 2 and the disk drive means 12 from the lower part.

[0008]

By the way, in order to prevent the occurrence of the above-mentioned bridging phenomenon in the hopper 2 as much as possible, it is disclosed in JP-A-59-191686 or JP-B-2-19882. As shown in the figure, a coin stirring bar with a spiral ridge is fixed at the center of rotation of the disc, and by rotating this coin stirring bar together with the disc, vertical thrust is exerted on each coin accumulated around it. It has been proposed to prevent the occurrence of bridges in the hopper as much as possible.

However, even in the case where the coin stirring bar having the spiral ridge formed at the center of rotation of the disk is arranged as described above, for example, as shown in FIG. 14 in which the same portions as those in FIG. 13 are designated by the same reference numerals. A large number of coin groups 4 are in a posture parallel to the longitudinal direction of the coin stirring rod 15 and the coin stirring rod 1
5 and the inner peripheral wall 2a of the hopper 2 are aligned, the thrust force of the coin stirring bar 15 in the vertical direction is not transmitted to the coin group 4, so that this bridge phenomenon is eliminated and the coins are smoothly dispensed. Could be impossible.

Further, in order to eliminate such a fear, FIG.
15, the coin agitation rod 15 is arranged eccentrically from the rotation center 5b of the disk 5, or the same parts as those in FIG.
The coin stirring bar 15 has an elliptical cross section as shown in
As a result, in a posture parallel to the longitudinal direction of the coin stirring bar 15, a thrust force in the direction of arrow C is applied to the coin group 4 aligned between the coin stirring bar 15 and the inner peripheral wall 2a of the hopper 2 to bridge the coins. It is possible to eliminate the phenomenon, but Fig. 1
As shown in FIGS. 5 and 16, the coin group 4 is the coin stirring bar 15
When tightly sandwiched between the longitudinal direction of the coin and the inner peripheral wall 2a of the hopper 2, rotation of each coin stirring bar 15 in the direction of the arrow B is hindered by the coin group 4 that is tightly sandwiched, The rotation of the disk 5 is locked, and in this case as well, it may be impossible to smoothly dispense coins.

In view of the above-mentioned circumstances, the present invention prevents the occurrence of the bridge phenomenon in the hopper and the rotation lock of the disc as much as possible, thereby enabling the disc body to be smoothly dispensed. An object is to provide a dispensing device.

[0012]

In order to solve the above-mentioned problems, according to the present invention, a hopper for temporarily storing a plurality of loaded discs and a rotatably supported at the bottom of the hopper are provided. At least a disk for ejecting a disk having concentric disk-conveying holes having a diameter slightly larger than the diameter of the disk for ejecting is provided, and the disk for ejecting the disk is a disk drive means. In the disc ejecting device in which the discs inserted into the disc conveying holes are ejected one by one to the outside of the hopper to be ejected by being rotated by A disk stirring means is provided which is freely movable in the hopper.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a disc body ejecting device according to the present invention will be described in detail below.

FIG. 1 shows a disk body ejecting device 2 according to the present invention.
12, the same parts as those in FIG. 12 are designated by the same reference numerals, and the coin payout opening 9, the substrate 10, the disk drive means 12, the support frame 13, and the like shown in FIG. 12 are omitted.

In the disc body ejecting device 20, the hopper 2
A disk-shaped stirring means 21 which can freely move inside the hopper 2 is provided therein.

In the embodiment shown in FIG. 1, the disc stirring means 21 is composed of a steel ball 22 made of a rigid body having a diameter slightly smaller than the diameter of the transport hole 6 formed in the disk 5. ing.

According to such a steel ball 22, the steel ball 22
Can move freely in the hopper 2.
2 shown in the CC enlarged cross-sectional view of FIG. 2, the steel balls 22 are fitted into one carrying hole 6 and a plurality of coin groups 4 stand vertically with respect to the disk 5 in the other carrying hole 6. Insert in the posture,
Even if a bridge phenomenon occurs there, the steel ball 22 collides with the inner peripheral edge of the transport hole 6 when the disk 5 rotates as shown by arrow B in FIG. 2 and moves above the hopper 2 as shown by arrow D in FIG. Alternatively, as shown by arrows E and F in FIG. 2, the hopper 2 is moved in the circumferential direction by receiving the propulsive force.

Then, as shown in FIG. 1, the coins 3 loaded on the upper surface of the coin group 4 or the coin groups 4 inserted into the respective transport holes 6 in a posture standing perpendicular to the disc 5 shown in FIG. Causes a change in posture due to the steel balls 22 slipping out of or moving from that location, which causes the bridge array of coins to collapse and the bridge phenomenon to collapse.

When the disk 5 rotates, the steel balls 22 do not stay in one place, so of course, as shown in FIG.
5, disk 5 resulting from the arrangement of coin group 4 shown in FIG.
The lock phenomenon of does not occur.

Further, as shown in FIG. 3 in which the same parts as in FIG. 1 are indicated by the same reference numerals, the inner peripheral wall 2b of the hopper 2 and the other inner peripheral wall 2c.
Even if a bridging phenomenon (so-called large bridging phenomenon) of the coin group 30 occurs due to a plurality of coins 3 being aligned between and, the steel balls 22 accelerate the rotation speed of the disk 5, It is possible to collide with the inner peripheral edge of the transport hole 6 and jump upward as shown by an arrow G in FIG. 3, collide with the coin group 30 in which the bridge phenomenon has occurred, and collapse the large bridge phenomenon.

Therefore, according to the disk stirring means 21 composed of the steel balls 22 described above, even if a bridge phenomenon of any shape caused by the plurality of coins 3 occurs in the hopper 2, the bridge phenomenon is generated in the hopper 2. By means of the steel balls 22 which are the disc stirring means 21 that move freely, the disk 5 can be disintegrated without causing the rotation lock.

In the above embodiment, as shown in FIG. 4, the disc-shaped stirring means 21 is made of a rigid steel having a diameter L1 slightly smaller than the diameter of the transfer hole 6 formed in the disk 5. Although the present invention is not limited to the above embodiment, the disk stirring means 21 has a total length L2 slightly smaller than the diameter of the transport hole 6 and a diameter L3 as well. The deformed spheres 30, which are slightly smaller than the diameter of the transport hole 6 and which are spherical rigid bodies at both ends, may be used. Further, as shown in FIG. 6, the disc stirring means 21 has a disc-shaped center and both ends are circular. It may be constituted by a deformed sphere 40 made of an abacus ball-shaped rigid body formed in a frustum shape. In that case, the total length L2 is slightly smaller than the diameter of the transport hole 6, and the diameter L3 is also smaller than the diameter of the transport hole 6. Form a little smaller.

In each of the above-mentioned embodiments, the disc stirring means 21 are made of steel balls 22 (FIG. 4), deformed spheres 30, each having a shape slightly smaller than the diameter of the transport hole 6 formed in the disk 5.
40 (FIGS. 5 and 6), the present invention is not limited to the above-described embodiment, and the disk-shaped stirring means 21 have a shape larger than the diameter of the transport hole 6 formed in the disk 5, respectively. It may be configured by a sphere.

FIG. 7 in which the same parts as those in FIG. 2 are designated by the same reference numerals shows an example in which the disk stirring means 21 are each formed by a deformed sphere 50 having a shape larger than the diameter of the transport hole 6 formed in the disk 5. Is.

As shown in FIG. 8, the deformed sphere 50 is made of a rigid body (stainless steel) having a substantially ellipsoidal shape (football shape), and its entire length L4 is formed larger than the diameter of the transport hole 6. The maximum diameter L5 is slightly smaller than the diameter of the transport hole 6.

The reason why the disk-shaped stirring means 21 is formed in the sphere 2 having a shape larger than the diameter of the conveying hole 6 formed in the disk 5 is as shown in FIG. When the number of coins held is small and all of them are inserted as coin groups 4 in the conveying hole 6 in a vertically standing posture, the deformed sphere 50 also enters the conveying hole 6 and is conveyed. When the disc 5 is rotated together with the disc 5 in the hole 6, there is a possibility that the deformed sphere 50 and the coin group 4 will not collide with each other.
The diameter is larger than the diameter.

As described above, when the irregularly shaped sphere 50 having a shape larger than the diameter of the transport hole 6 is used, the irregularly shaped sphere 50 is not fitted into the transport hole 6, so that a part of the irregularly shaped sphere 50 is necessarily the inner peripheral edge of the transport hole 6. 7 and the propulsive force moves in the circumferential direction of the hopper 2 as indicated by arrows E and F in FIG. 7, whereby the deformed sphere 50 surely collides with the coin group 4 and collapses the bridge array of coins. It becomes possible to do.

The disc stirring means 21 constituted by a deformed sphere having a shape larger than the diameter of the transfer hole 6 formed in the disc 5 is not limited to the above embodiment, but may be centered as shown in FIG. May be constituted by a deformed sphere 60 having a shape in which a pair of disc-shaped spheres are continuously arranged, or may be constituted by a deformed sphere 70 having a shape in which a pair of spheres are continuously arranged as shown in FIG. Further, as shown in FIG. 10, it may be configured by a deformed sphere 80 having a shape in which two abacus ball-shaped rigid bodies having a disk shape at the center and a truncated cone shape at both ends are connected in series.

In the case of the deformed spheres 60, 70 and 80 shown in FIGS. 9, 10 and 11, the total length L4 is larger than the diameter of the conveying hole 6, and the diameter L5 is the conveying hole 6.
Is formed to be slightly smaller than the diameter of.

[0030]

As described above, in the disc body ejecting apparatus of the present invention, even if a bridge phenomenon of any shape due to a plurality of disc bodies occurs in the hopper, the bridge phenomenon occurs in the hopper. Since the disc stirring means that can move freely allows the disc to be collapsed without causing rotation lock, it is possible to always smoothly dispense the disc.

Further, in the disc body discharging device of the present invention, the disc body stirring means is constituted by a steel ball or a rigid deformed sphere having an extremely simple structure, and the steel ball or deformed sphere is thrown into the hopper. Since it is a simple structure, the structure is simple and the number of parts is small. Therefore, it is possible to provide a disc body ejecting device which can always smoothly eject the disc body at a very low cost.
