Description

[Detailed description of the invention] [Industrial application field] This invention relates to a coin sorting device used in vending machines, money changers, entertainment machines, etc. This invention relates to improvements in a rail-type coin sorting device that sorts coins into coin passages.

[Conventional technology]

Generally, a coin sorting device is a primary sorting device that determines whether a coin inserted through a coin input slot is genuine or counterfeit, and separates the determined genuine coins and counterfeit coins into designated coin passages. and a coin sorting device that sorts and sorts the sorted genuine coins into predetermined coin passages for each denomination.

Among these, the conventional coin sorting device that sorts the primary sorted specie coins by denomination uses an inclined rail to transfer the coins, and the coins transferred on this inclined rail are divided into different diameters. Therefore, there is a so-called rail-type coin sorting device that sorts coins into special coin passages. FIG. 8 is a conceptual perspective view showing a conventional example of the above-mentioned rail-type coin sorting device, and particularly shows a rail-type coin sorting device 1 for sorting and sorting two types of coins A and B, large diameter and small diameter. .

This rail-type coin sorting device 1 has a sub-plate 2 that covers a main plate of a coin sorting device (not shown).
It is composed of a first coin passage 3 formed in a. This first coin passage 3 includes an inclined rail 4 that guides coins to be transferred, and a first coin passageway 3 that is inclined at a predetermined angle with respect to a vertical plane of the inclined rail 4 in the coin transfer direction.
and a second inclined wall 5 formed upstream of this first inclined wall 5 and inclined at a predetermined angle with respect to a plane perpendicular to the coin transfer direction than the first inclined wall 5.
It is composed of an inclined wall 6. Among these, the height L of the first inclined wall 5 is the diameter M of the large-diameter coin A.
(L>M), and the second
The height N of the inclined wall 6 is slightly larger than the diameter O of the small-diameter coin B, and smaller than the diameter M of the large-diameter coin A (O<N<M). On the other hand, the downstream end 4a of the inclined rail 4 faces the upstream end 7a of a second coin passage 7 that is vertically arranged downward and guides large-diameter coins A, and the second inclined wall 6
A third coin passage 8 for guiding small-diameter coins B vertically downward is connected to the side of the inclined rail 4 in the vicinity of the downstream end 6b, and the upstream end 8a of the third coin passage 8 is It faces into the first coin passage 3. A main plate (not shown) that covers the sub-plate 2 upstream of the first coin passage 3 is provided with a main plate (not shown) that covers the sub-plate 2 upstream of the first coin passage 3. A protruding wall 9 that is pushed down to the side is formed.

According to the rail-type coin sorting device 1 described above,
When a large-diameter coin A is guided into the first coin passage 3, the coin A is guided into the first and second coin passages by the protruding wall 9.
However, since the diameter M of the coin A is larger than the height N of the second inclined wall 6, the coin A comes into contact with the upper edge 5a of the first inclined wall 5. While maintaining this state, the coins are transferred downstream of the inclined rail 4, and are distributed and guided into the second coin passage 7. Furthermore, when a small-diameter coin B is guided into the first coin passage 3, the coin B is pushed down toward the first and second inclined walls 5 and 6 by the protruding wall 9; Since the diameter O is smaller than the height N of the second inclined wall 6, it immediately contacts the slope 6a of the second inclined wall 6, and while maintaining this state, moves along the second inclined wall 6 to its downstream end 6b. Thereafter, it comes into contact with the triangular wall 10 connecting the downstream end 6b of the second inclined wall 6 and the first inclined wall 5, and its progress is blocked. The small-diameter coin B, which has been blocked from proceeding downstream on the inclined rail 4, is transferred to the inclined surface 6a of the second inclined wall 6.
The coins slide toward the upstream end 8a of the third coin passage 8 due to the component force of their own weight acting along the axis, and are distributed and guided into the third coin passage 8.

[Problem that the invention attempts to solve]

By the way, according to the conventional rail-type coin sorting device 1 described above, the first coin passage 3 shown in FIG.
As shown in Figure 9, which is a cross-sectional view of
When the small-diameter coin B is guided into the first coin passage 3, the small-diameter coin B is pushed down toward the second inclined wall 6 by the protruding wall 9 protruding from the main plate 11.
At that time, as shown in FIG. 10 showing the cross section CC in FIG. As a result, the coin B rises again from the tilted state as shown by the arrow, and the triangular wall 1

As shown in FIG. 9, there was a problem in that the coins were erroneously sorted and guided into the second coin passage 7.

[Means and actions for solving problems]

In this invention, there is an inclined rail that transfers two types of coins, large and small diameter, and on the side of the inclined rail,
a first inclined wall that is inclined at a predetermined angle with respect to a vertical plane in the coin transfer direction of the inclined rail and whose height is slightly larger than the diameter of the large-diameter coin; , a second inclined wall is formed to be inclined at a predetermined angle with respect to a vertical plane in the coin transfer direction than the first inclined wall, and has a height larger than the diameter of the small diameter coin and smaller than the diameter of the large diameter coin. wall and
A projecting wall is provided at a position opposite to the second sloped wall, and coins guided from upstream of the sloped rail are transported to the first sloped wall.
and a protruding wall that is pushed down toward the second inclined wall, and a protruding wall that is formed at a connecting portion between the downstream end of the second inclined wall and the first inclined wall, and that is in contact with the second inclined wall while pushing down the inclined wall. a first coin passageway having a wall portion that changes the traveling direction of the coins transferred in the downstream direction of the rail;
A second coin, which is disposed at the downstream end of the inclined rail, is pushed down against the first inclined wall by the protruding wall, and guides a large-diameter coin that is transferred while coming into contact with the slope of the first inclined wall. A coin passage is formed below the protruding wall with an upstream end facing into the first coin passage, and is pushed down by the protruding wall to the second inclined wall, and the inclined rail is pushed down by the wall. The third guide guides the coin whose progress in the downstream direction has been changed.
In the rail-type coin sorting device comprising a coin passage, a convex portion whose height decreases toward the downstream side of the second slope wall is formed on the slope of the second slope wall, and the protrusion bringing a small diameter coin pushed down by the wall toward the second inclined wall into contact with the convex portion;
As the small-diameter coin is transferred downstream of the second inclined wall, the small-diameter coin is gradually brought into contact with the inclined surface of the second inclined wall, and thereby the small-diameter coin is pushed down onto the inclined surface of the second inclined wall. This prevents the coin from bouncing back due to the reaction of the inclined surface, thereby preventing the coin sorting function from malfunctioning in the rail-type coin sorting device.

〔Example〕

Hereinafter, one embodiment of the rail-type coin sorting device according to this invention will be described in detail.

FIG. 1 is a conceptual perspective view of a rail-type coin sorting device 20 according to this invention, and the same parts as in FIGS. 8 to 10 are designated by the same reference numerals.

In this rail-type coin sorting device 20, a convex portion 21 that protrudes in the width direction of the inclined rail 4 is formed above the upstream side of the second inclined wall 6, and a convex portion 21 that projects toward the width direction of the inclined rail 4 is formed below the second inclined wall 6. A notch 22 having a J-shaped cross section is formed in a portion connected to the inclined rail 4 from the upstream to the downstream of the second inclined wall 6. Among these, the height H of the convex portion 21 is configured to gradually decrease from upstream to downstream of the second inclined wall 6, and the notch 22 is configured such that the height H thereof gradually decreases from the upstream side to the downstream side of the second inclined wall 6.
The inclined wall 6 has an arcuate portion 22a in a portion located on the downstream side.

Next, the operation of the rail-type coin sorting device 20 described above will be explained, and the configuration will also be explained in more detail.

When a large-diameter coin A is thrown into the upstream side of the inclined rail 4, this large-diameter coin A will move as shown in FIG.
The protruding wall 9 bends its advancing direction and pushes it down toward the first inclined wall 5 side. The pushed down large-diameter coin A is transferred to the downstream side of the inclined rail 4 while contacting the upper edge 5a of the first inclined wall 5, and as a result, the second coin A connected to the downstream side 4a of the inclined rail 4 is transferred. The coins are guided into the coin passage 7. Therefore, the large diameter coins A are sorted into the second coin passage 7.

On the other hand, when the small-diameter coin B shown in FIG. As a result, its direction of movement is bent and it is pushed down toward the second inclined wall 6. At this time, a convex portion 21 is formed above the second inclined wall 6 and a notch 22 is formed below, so that the upper surface of the coin B is formed with the convex portion 21 and the lower surface thereof is formed with the notch 22. in contact with the periphery of
The entire upper surface of the pushed down coin B does not immediately come into contact with the inclined surface 6a of the second inclined wall 6, but gradually comes into contact with it.
Therefore, the coin B does not come into contact with the inclined surface 6a of the second inclined wall 6 as in the conventional case and bounce back due to the reaction and return to its original upright state again. The small-diameter coin B that comes into contact with the periphery of the convex portion 21 and the notch 22 and is transferred along the inclined rail 4 is coin A as shown in FIG. The upper surface of the convex portion 21 gradually becomes second along the height H.
The lower surface is in contact with the slope 6a of the slope 6 of the notch 2.
The coins are guided while moving in the width direction of the inclined rail 4 along the arcuate portion 22a formed at the downstream end of the coin passage 2, that is, toward the third coin passage 8 (the fifth coin passage 8).
figure). When the coin B is transferred to the downstream side of the inclined rail 4 while undergoing such a change in the direction of travel, the small diameter coin B is shown in FIG. 6 and FIG. As shown in FIG. 7 shown in the EE cross section, the tip B1 (FIG. 6) of the coin B comes into contact with the wall 10 formed at the joint between the second inclined wall 6 and the first inclined wall 5. , the downstream movement of the inclined rail 4 is changed, and the circular arc-shaped portion 22a of the notch 22 allows the lower surface B2 (seventh
Since a force is applied to the inclined rail 4 in the width direction of the inclined rail 4, that is, toward the upstream end 8a of the third coin passage 8, the coin B smoothly changes its course toward the third coin passage 8, and You will be guided inside. Therefore, the small diameter coins B are smoothly sorted and sorted into the third coin passage 8.

[Effect of idea]

In this invention, two coins with different diameters to be transferred on an inclined rail are pushed down toward two inclined walls having different heights and angles of inclination, thereby causing each coin to be guided while contacting the inclined walls. In a rail-type coin sorting device for sorting coins into a predetermined coin passage, one of the inclined walls has a height upstream of the inclined wall that guides small-diameter coins, and a height that extends toward the downstream of the inclined wall that guides the small-diameter coins. Therefore, by forming a convex part that decreases so that the coin pushed down against the slope wall gradually comes into contact with the slope of the slope wall, the coin pushed down immediately comes into contact with the slope of the slope wall, and at that time, the slope of the slope increases. It is possible to prevent the phenomenon of coins bouncing back and standing up again due to reaction, thereby reducing malfunctions in sorting as much as possible, and providing a rail-type coin sorting device having a stable sorting function.
