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. 6 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, which will be described later.
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. Further, a main plate (to be described later) that covers the sub-plate 2 upstream of the first coin passage 3 comes into contact with a coin passing through the first coin passage 3 and transfers the coin to the first coin passage 3. A protruding wall 9 that is pushed down toward the inclined walls 5 and 6 is integrally 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 comes into contact with the protruding wall 9 and is pushed down toward the first and second inclined walls 5 and 6; Since the diameter M of A is larger than the height N of the second inclined wall 6, the coin A contacts the upper edge 5a of the first inclined wall 5 and is transferred downstream of the inclined rail 4 while maintaining this state. , are sorted 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 comes into contact with the protruding wall 9 and is pushed down toward the first and second inclined walls 5 and 6; B
Since the diameter O is smaller than the height N of the second inclined wall 6, the second inclined wall 6 immediately comes into contact with 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, and then 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 coin slides toward the upstream end 8a of the third coin passage 8 due to the component force of its own weight acting along the axis, and is distributed and guided into the third coin passage 8.

[Problem that the invention aims to solve]

By the way, according to the conventional rail-type coin sorting device 1 described above, as shown in the enlarged perspective view of the main part of the protruding wall 9 shown in FIG. Since the coins (A, B) passing through 3 are always in contact with this wall surface 9a,
The circumferential surface of the protruding wall 9 is susceptible to wear and damage, and when wear and damage occur on the wall surface 9a and the circumferential surface of the protruding wall 9, passing coins A and B are reliably pushed toward the inclined walls 5 and 6. Therefore, there was a problem in that the coins could not be sorted and sorted accurately. Furthermore, if wear or damage occurs on the wall surface of the protruding wall 9, the entire main plate 11 that integrally forms the protruding wall 9 must be replaced, which makes maintenance and inspection work complicated and wastes time. There was also the problem that the costs involved were high.

[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,

〔Example〕

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

FIG. 2 is a conceptual perspective view of a rail-type coin sorting device 20 according to this invention, and the same parts as in FIGS. 6 and 7 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. On the other hand, as shown in FIG. 1, which is an enlarged perspective view of the main part in FIG. A metal plate 23 is disposed thereon. This metal plate 23 is bent along the circumferential surface of the protruding wall 9,
Furthermore, both ends 23a and 23b are formed into an L shape. In addition, rectangular holes 11a and 11b are formed in the main plate 11 with which the protruding wall 9 is integrally formed, at positions facing both ends 23a and 23b of the metal plate 23. In this way, the holes 11a, 11 in the main plate 11
b, and both ends of the metal plate 23 are formed into an L shape, this plate 23 is elastically bent, and each end 23a, 23 of this plate 23 is bent.
b into the corresponding holes 11a and 11b, the plate 23 can be easily attached to the circumferential surface of the protruding wall 9, and by performing the reverse operation, the plate 23
can be easily removed from the protruding wall 9.

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 as shown in FIG. 2, the large-diameter coin A comes into contact with the wall surface 9a of the protruding wall 9 shown in FIG. It is bent and pushed down to the first inclined wall 5 side. At this time, since a metal plate 23 is disposed on the wall surface 9a of the protruding wall 9, the large diameter coin A does not directly contact the wall surface 9a of the protruding wall 9, but contacts the plate 23. Wear and damage to the protruding wall 9 will be prevented as much as possible. As shown in FIG. 2, the large-diameter coin A pushed down by the projecting wall 23 is transferred downstream of the inclined rail 4 while contacting the upper edge 5a of the first inclined wall 5. As a result, the inclined rail 4 The coins are guided into a second coin passage 7 connected to the downstream side 4a of the coin passage 7. Therefore, the large diameter coins A are sorted and 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, since the metal plate 23 is disposed on the wall surface 9a of the protruding wall 9, the small diameter coin B does not directly contact the wall surface 9a of the protruding wall 9, similar to the large diameter coin A. plate 23
As a result, wear and damage to the protruding wall 9 is prevented as much as possible. Further, when the small-diameter coin B is bent in its traveling direction by the protruding wall 9 and pushed down toward the second inclined wall 6, a convex portion 21 is formed above the second inclined wall 6 upstream. Since a notch 22 is formed at the bottom, the top surface of the coin B comes into contact with the convex part 21 and the bottom surface comes into contact with the periphery of the notch 22, and the entire top surface of the coin B that is pushed down immediately hits the second inclined wall. It does not come into contact with the inclined surface 6a of No. 6, but gradually comes into contact with it. 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 gradually contacts the slope 6a of the second slope 6 along the height H of the convex portion 21,
The lower surface is guided while moving along the arcuate portion 22a formed at the downstream end of the notch 22 in the width direction of the inclined rail 4, that is, toward the third coin passage 8 (FIG. 5). When the coin B is transferred to the downstream side of the inclined rail 4 while undergoing such a change in the traveling direction, the leading end B1 (FIG. 4) of the coin B is moved between the second inclined wall 6 and the first inclined wall 5. The downward movement of the inclined rail 4 is changed by the lower surface B2 (fifth
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, the protruding wall of the rail-type coin sorting device that transfers two coins with different diameters on an inclined rail by pushing them down to the side of two inclined walls with different heights and angles of inclination is installed to protect the protruding wall. Since a metal plate is provided for the purpose, wear and damage on the protruding wall is prevented as much as possible, and therefore, it is possible to provide a rail-type coin sorting device in which the initial characteristics of sorting accuracy are maintained for a long period of time. . In addition, since the protruding wall protection plate is removably attached to the protruding wall, maintenance and inspection work when this plate wears out is extremely easy, and the entire main plate that forms the protruding wall can be replaced as usual. Since it is only necessary to replace the plate for protecting the protruding wall without having to do any maintenance, the cost required for maintenance and inspection can be significantly reduced.
