Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorter, and more particularly to a coin sorter for eliminating coins having an incorrect diameter and thickness.

[0002]

2. Description of the Related Art Conventionally, in a coin / token sorting machine, regardless of whether it is a cradle type or a gutter type, the function of the sorting section has been to utilize the natural fall or rolling of coins due to potential energy.

[0003]

However, in the conventional coin sorter described above, since the potential energy of the coins to be sorted is utilized, the design requires a certain size in the vertical direction, which is a design problem. There was a problem that it might become a constraint of. Moreover, if the measurement accuracy of the equipment part that sorts the coins is increased to improve the sorting accuracy, the drop motion and rolling property in the sorting part become unstable,
There is also a problem that the probability that coins will stop inside the coin sorter increases.

The problem to be solved by the present invention is to improve the passage efficiency of coins by forcibly passing the coins at the time of coin selection, and to reduce the design restrictions.

[0005]

The present invention is to achieve the above-mentioned object. The coin sorter according to claim 1 is formed to have a lower surface support portion that supports a lower surface of a circular surface of a coin, and a coin moving portion that moves the coin along the lower surface support portion. Is a drop hole having an inner diameter slightly smaller than the diameter of a proper coin having a predetermined diameter and a thickness, and a coin that is parallel to the moving direction of the coin by the coin moving section and is positioned on both sides of the drop hole. A pair of placing edges that support a part of the lower surface of the coin, and an illegal coin that is located on one side of both placing edges and is thicker than the proper coin, moves in a direction approaching the other placing edge, A thickness measurement scale that is formed with an obliquely upward slant that moves an illegal coin that is thinner than an appropriate coin toward the other mounting edge in a direction that approaches it, and a moving coin that is slanted on the slant of the thickness measurement scale. A biasing part that biases the part toward Wherein the coin moving unit is configured to face the lower surface support portion, characterized in that it is formed by an endless chain mechanism which moves the coins endless belt comes into contact with the upper surface of the circular face of the coin.

[0006]

[Operation] According to the coin sorter of the first aspect, the following operation is achieved. First, the endless chain mechanism of the coin moving unit operates. Then, the endless belt of the endless chain mechanism contacts the upper surface of the coin to move the coin. At the same time, the urging unit urges the moving coin toward the inclined portion of the thickness measurement scale. The coin moves along the placement edge by the coin moving unit, and a part of the upper surface thereof contacts the slant portion of the thickness measurement scale.

When the moving coin is smaller than the diameter of the proper coin, the side opposite to the thickness measuring scale of the coin is disengaged from the placing edge, so that the coin falls from the drop hole. If the moving coin is thicker than the proper thickness, a part of the upper surface of the coin contacts the slant part of the thickness measurement scale, but the lower surface of the coin comes off the mounting edge, so the coin drops from the drop hole. To do.

When the moving coin has the same diameter as the proper coin and a small thickness, a part of the upper surface of the coin comes into contact with the slant portion of the thickness measuring scale, and the lower surface thereof is also supported by the placing edge. Due to the urging of the urging unit, the coin moves to the back of the thickness measurement scale, and the lower surface of the coin on the opposite side of the thickness measurement scale comes off the mounting edge, so that the coin falls from the drop hole.

Thus, only coins having the same diameter and thickness as the proper coin can pass through the coin sorter of the present invention.

The present invention will be described in more detail with reference to the following examples and drawings. 1 and 2 are vertical cross-sectional views showing the main part of a coin sorter according to an embodiment of the present invention. FIG. 3 is a perspective view showing a coin sorter according to an embodiment of the present invention. The coin sorter of this embodiment has a lower surface supporting portion 20 that supports the lower surface of the circular surface of the coin 10 and the coin 10 along the lower surface supporting portion 20.
And a coin moving part 30 for moving the.

The lower surface support portion 20 has a drop hole 29 having an inner diameter slightly smaller than the diameter of the proper coin 10 having a predetermined diameter and thickness. The inside diameter of the drop hole 29, which is slightly smaller than the diameter of the proper coin 10,
Is an inner diameter perpendicular to the moving direction of the coin 10, and an inner diameter parallel to the moving direction of the coin 10 is formed to be larger than the diameter of the proper coin 10, for example, formed in an elliptical shape that is long in the moving direction of the coin 10. .. The drop hole 29 is not limited to the oval shape, and may be formed in an elliptical shape or a rectangular shape.

Further, a pair of left and right placing edges 21 and 22 for supporting the left and right edges of the lower surface of the proper coin 10 are formed on the left and right edges parallel to the movement direction of the effect 10 of the drop hole 29. On one of the two mounting edges 21, 22 such as the mounting edge 22 on the right side in FIG. 1 and FIG.
The illegal coin 12 thicker than 0 is moved to the other side, that is, in the direction toward the mounting edge 21 on the left side, and the illegal coin 12 thinner than the proper coin 10 is moved toward the mounting edge 21 on the left side. A thickness measuring scale 24 having an inclined portion 23 that moves diagonally upward is formed.

The thickness measuring scale 24 has a substantially U-shaped vertical cross section, has a vertical surface 25 which rises substantially vertically from the upper surface of the roadside mounting edge 22, and a slant portion 23 from the upper end of the vertical surface 25. Extends diagonally upward. That is,
The lower surface of the inclined portion 23 is formed as an inclined surface forming an obtuse angle with the vertical surface 25. Specifically, the member forming the vertical surface and the inclined surface is a plate material bent at an obtuse angle, and the member forming the bottom surface is formed by a plate material fixed perpendicularly to the vertical surface.

A biasing portion 26 for biasing the coin 10 moving on the placing edge 21 toward the slant portion 23 of the thickness measuring scale 24 is provided. The biasing portion 26 is a combination of a spring and a pressing plate. The coin moving unit 30 is formed by an endless chain mechanism that moves the coins by contacting the upper surface of the circular surface of the coin 10. That is, the drive roller 32,
It is an endless chain mechanism formed of an auxiliary roller 33 and an endless belt 31 wound around the rollers 32, 33, and the endless belt 31 faces the lower surface support portion 20. Further, the drive roller 32 is the drive motor 3
