Description

[Detailed description of the invention] (Field of industrial application) The present invention stores a large number of coins or medals in a hopper, and as required, rotates a coin feeding disk to transfer coins from the hopper to a single designated destination. The present invention relates to a coin dispensing device that dispenses several coins, and in particular to a means for stirring coins in a hopper of this type of coin dispensing device.

(Prior Art) Conventionally, as a coin stirring means of such a coin feeding device, an elastomer of a predetermined thickness is coated on the surface of the central platform of a coin feeding disk, as described in, for example, Japanese Unexamined Patent Publication No. 54-5498. A radial-shaped stirring member made of wood is fixed, or a truncated pyramid-shaped protrusion protrudes from the center of the coin feeding disc as described in Japanese Utility Model Publication No. 19646/1983, and the ridgeline part is stirred. A device configured as an element, or a plurality of coil springs extending radially from the center of the coin feeding disk along the surface of the central platform as described in Japanese Patent Application Laid-open No. 100278/1983. Monoya, Jikko 52-
As described in Publication No. 33277, a plurality of stirring members are protruded from the surface of the peripheral part of the central platform of the coin feeding disk at positions spaced apart in the circumferential direction, and as described in Publication No. 55-33409. As described in the official gazette, various structures are available depending on the type of coin dispensing device, such as a stirring plate fixed to the central platform of a rotating disk with stirring claws protruding from both ends. Known.

(Problems to be Solved by the Invention) However, as described above, the conventional stirring member or stirring element pushes the coins located near the surface of the coin feeding disk in the hopper in the direction of rotation of the coin feeding disk. Since the coins are stirred, there is a problem in that coins may become stagnant in a portion of the hopper that is spaced upward from the surface of the coin feeding disk, or a bridging phenomenon may occur.

For example, in the coin dispensing device of the type disclosed in Japanese Unexamined Patent Publication No. 54-5498, a stagnation portion occurs at the coin exit portion and prevents the normal delivery of coins.
In the coin dispensing device of the type disclosed in Publication No. 19646,
There is a problem in that coin bridging occurs in the upper part of the hopper.

In order to prevent the above-mentioned coin stagnation and bridging from occurring in the hopper, the length of the stirring member that extends radially along the surface of the coin feeding disk is increased, and the protrusion that protrudes from the surface of the disk is increased. It is conceivable to increase the stirring capacity by increasing the height of the coin feeder, but since all conventional stirring members or elements are located radially away from the rotation axis of the coin feeding disk, the stirring member Alternatively, if the size of the element is increased, the stirring resistance increases significantly, and there is a problem that the rotational load on the coin feeding disk that rotates together with the stirring member increases.

The purpose of the present invention is to solve the above-mentioned problem, and is to prevent coin stagnation, bridging, etc. in the portion of the hopper that is spaced upward from the surface of the coin feeding disk in the hopper, regardless of the shape and dimensions of the hopper. The object is to provide a stirring means that can be efficiently eliminated without creating a large load.

(Means for Solving the Problems) As shown in FIG. 1, the present invention provides a coin feeding device that includes a hopper 1 that accommodates a large number of coins, and a coin feeding disk 3 that is rotated within the hopper. In the device, a coin stirring rod 9 made of elastomer-like elastic material is extended into the hopper from approximately the center of the coin feeding disk 3 at a slight angle to the axis of rotation of the coin feeding disk.
It is characterized by having a protrusion 19 at its tip.

(Function) According to the above-described configuration, when the coin feeding disk 3 rotates, the stirring rod 9 made of an elastic and flexible elastomer material rotates approximately on the axis of rotation of the disk, thereby increasing the load on the rotation. is slight,
A protrusion 19 is provided at the tip of the stirring rod 9 that is inclined with respect to the axis of rotation of the disk, thereby stirring the coins located at a portion away from the coin feeding disk 3, thereby causing the coin feeding disk in the hopper to move. It is possible to prevent coin stagnation or bridging in a portion spaced upward from the surface.

(Embodiment) The drawing shows an embodiment of the present invention, in which 1 is a hopper that accommodates a large number of coins, and this hopper 1 is mounted on a support plate 2 that is inclined with respect to the horizontal. Coin feed disk 3 is placed on support plate 2.
A circular center shelf 4 is provided on the coin feed disk 3, and a large number of coin feed protrusions 5 are provided between the center shelf 4 and the outer periphery of the coin feed disk 3. provided on the disk 3, thereby
When the coin feed disk 3 is rotated around the center disk rotating shaft 6, the coins in the hopper 1 are picked up one by one by the coin feed protrusion 5 and sent out through an outlet chute (not shown). It is configured so that

In the illustrated example, a stirring member 8 having a plurality of arms 7 extending radially in the radial direction is provided on the central shelf 4 of the coin feeding disk 3, and a main body is provided at the center of the radial stirring member 8. The coin stirring rod 9 according to the invention is installed at an angle.

The coin stirring rod 9 is made of an elastomer-like elastic material such as urethane. In order to mount the agitation rod 9 on the coin feeding disk 3 at an approximately center position of the coin feeding disk 3 at an angle with respect to the axis of rotation of the coin feeding disk, a truncated conical mounting member 10 is used. The screw portion 11 provided on the bottom surface of the mounting member 10 is connected to the disc rotation shaft 6 through the center hole 12 of the radial stirring member 8.
Screw it into the center screw hole 13 and tighten it.
14 indicates a tightening tool engagement hole.

The truncated conical mounting member 10 is provided with an inclined mounting hole 15 that opens at its upper end surface 10a.
5, insert the base end 9a of the stirring rod 9 into the base end 9a, align the horizontal hole 16 provided in the base end 9a with the horizontal hole 17 provided horizontally through the truncated conical mounting member 10, and Spring pins 18 are driven into the horizontal holes 16 and 17 to fix the base end 9a of the stirring rod 9 to the inclined mounting hole 15.

A protrusion 19 is provided on the tip 9a of the coin stirring rod 9. In the illustrated example, only one downward protrusion 19 is provided, but a plurality of protrusions may be provided radially as required.

(Effect of the invention) According to the invention, the coins located in the part of the hopper away from the surface of the coin feeding disk can be reliably stirred by the rotation of the coin feeding disk without creating a large load. , it is possible to prevent coin stagnation or bridging phenomenon in the hopper from occurring.
