Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coin sorting device used in public telephones, vending machines, etc., and particularly to a coin sorting device of the type that is equipped with a coin track for sorting and storing different types of coins. Concerning improvements to coin sorting devices.

[Conventional technology]

Various types of coin sorting devices used in public telephones, etc., have been proposed that can simultaneously use different types of coins, such as 10 yen coins and 100 yen coins, but all of these conventional structures have advantages and disadvantages. However, no one has yet been proposed that has a simple structure, is easy to mold and assemble, and can be made smaller and more compact as a whole.

For example, as described above, as a coin sorting device that uses two or more types of coins at the same time, the present applicant has developed a system in which coin input ports for different types of coins are arranged side by side in the radial direction of the coins, as disclosed in Japanese Patent Application Laid-Open No. 55-66086. We have previously proposed a device in which each coin track is arranged in parallel on both the left and right sides of the substrate using a single substrate and a side plate provided below the substrate.

[Problem that the invention seeks to solve]

However, in such conventional devices, each coin track is simply arranged in the plane direction (radial direction of the coin) on both the left and right sides of the board. The width of the substrate is twice as large as that required when one coin track is provided, and this increases the size of the device in the width direction of the substrate. In particular, the above-mentioned coin track has an appropriate length in order to suppress the rolling speed of the coin and dampen the jumping of the coin during rolling when the coin is guided from the coin input slot to the sorting mechanism section. In addition, when sorting is performed in the coin sorting mechanism, it is also necessary to keep the rolling speed of coins constant and to ensure an appropriate length to ensure sorting accuracy. Moreover, the space in the height direction for arranging this coin track is also limited by the space between the coin slot and the safe on the coin storage side, so it is provided meandering in the left and right direction on the board. In a conventional device in which coin tracks, which require a certain width dimension, are simply arranged side by side on the left and right sides of the board, it is inevitable that the board will become larger in the width direction. It is hoped that countermeasures will be taken.

[Means for solving problems]

In order to meet such demands, the coin sorting device according to the present invention includes a substrate that forms a coin track that is continuous with different types of coin input ports that are arranged in parallel in the radial direction of the coins by being placed opposite to the side plate. , the left and right sides are integrally formed of a synthetic resin material so as to have a step in the thickness direction of the coin, and a part of each coin track formed on these left and right sides is formed in the thickness direction of the coin. A guide member that intersects three-dimensionally and has side surfaces on both sides that form the orbital surface of each coin trajectory facing the base plate and the side plate with respect to the intersection part is rotated in the thickness direction of the coin between the base plate and the side plate. It is mounted on a shaft so that it can move freely.

[Effect]

According to the present invention, coins inserted from different types of coin input ports arranged in parallel in the radial direction of the coins are handled by the respective track sections formed on both side surfaces of the guide member and three-dimensionally intersecting in the thickness direction of the coins. Through the
It can be rolled on the coin tracks formed on both the left and right sides of the board, thereby ensuring the required track length for each coin track and increasing the width dimension in the left and right directions of the board. It is possible to make it smaller.

[Example] Hereinafter, the present invention will be explained in detail using an example shown in the drawings.

FIGS. 1 and 2 show an embodiment of a coin sorting device according to the present invention, and in these figures, this coin sorting device is adopted in, for example, a public telephone, and is used. different types of coins
The case where there are 10 yen coin A and 100 yen coin B will be explained.

First, to briefly explain the general configuration of this coin sorting device, in the figure, 1 is a board fixed to a housing (not shown) of a public telephone, etc., and 2 is a board whose upper end is connected to the board 1 via a shaft 3. The coin tracks 5 of each coin A and B are supported rotatably by a U-shaped spring 4 and are normally biased toward the substrate 1 side, facing the above-mentioned substrate surface at a predetermined distance. , 6, and at the upper end of the base plate 1, a coin slot member 7 that forms coin slots 7a and 7b arranged in parallel in the radial direction of coins is attached and fixed with screws or the like. There is. In addition, in the figure, 8A and 8B are coin sorting track sections 9A and 9B that are provided in the middle of the above-mentioned coin tracks 5 and 6 to sort each coin A and B.
10 is a coin storage track section for temporarily storing the sorted regular coins A and B, and 10 is the above-mentioned coin sorting track section 8.
Pseudo coins and storage track section 9 sorted in A and 8B
This is a return track section that guides return coins returned from A and 9B to a return port (not shown). In addition, 11a in the figure,
11b is a coin gauge for sorting the outer diameter and thickness of coins in the sorting track sections 8A and 8B, 12a and 12b are lightweight sorting levers for sorting coins, and 13a and 13b are storage levers for each coin. , 14a, 14b are return levers, and the operating states of these parts and the configurations of other parts are substantially the same as conventionally known configurations, and detailed explanation thereof will be omitted.

Now, according to the present invention, in the coin sorting device having the above-described configuration, the coin tracks 5 and 6 that are continuous with the different types of coin input ports 7a and 7b arranged in parallel in the radial direction of the coins are provided on both the left and right sides. The substrate 1 formed together with the side plate 2 is made entirely of a synthetic resin material so that its left and right sides have a step D in the thickness direction of the coin, and a portion of each coin track 5, 6 is made of a synthetic resin material. A guide member 20 is disposed three-dimensionally intersecting in the thickness direction of the coin, and is rotatably supported between the base plate 1 and the side plate 2 at this intersection, and this guide member 20 both sides 20
It is characterized in that the raceway surfaces of the respective coin tracks 5 and 6 are formed at points a and 20b.

To explain this in detail, in order to solve the problem of increasing the size of conventional coin sorting devices, especially increasing the size in the width direction due to forming coin tracks of different types of coins in the left and right directions of the board 1. According to the present invention, steps D in the thickness direction of the coin are provided on both the left and right sides of the substrate 1 formed of a synthetic resin material, and these are used as the coin tracks 5 and 6, respectively. By three-dimensionally intersecting a part of each coin track 5, 6, which is formed with a phase shift in the thickness direction, the dimension of the width direction of the entire device can be reduced and its size can be reduced. It is.

The problem with adopting this type of configuration is that in public telephones that generally use this type of coin sorting device, the coins are arranged side by side in the thickness direction for reasons of appearance and usage. This is a configuration for communicating the coin input ports 7a, 7b of each of the coins A, B, and the coin tracks 5, 6 provided offset in the thickness direction of the successive coins.
That is, the coin track 5 on one side (10 yen coin A side) continues to the coin slot 7a and is directly connected to the board 1.
Since it is formed in the same plane between the side plate 2 and the side plate 2, there is not much problem, but
Since the coin track 6 is formed at a position shifted from the coin slot 7b in the thickness direction of the coin, it is necessary to allow coins to roll smoothly and appropriately in this part. Therefore, according to the present invention, as described above, one side surface 20b of the guide member 20 disposed between the tracks 5 and 6 is formed as an inclined guide surface as shown in FIG. Further, a guide surface 6a is also formed on a portion of the side plate 2, which is similarly inclined and continuous with the above-mentioned guide surface 20b. In addition, this guide member 2
0 is supported by the coin slot member 7 by a shaft 21 so as to be rotatable in the thickness direction of the coin, and thereby the track 6 side formed by the guide member 20 and the base plate 1 It is constructed so that coin jams can be easily resolved.

In the coin sorting device having such a configuration, as shown in FIG. 3a, FIG. 4a, and FIG. 5a, coins inserted from the coin slot 7a
The 10 yen coin A rolls in the coin track 5 and is guided using one side surface 20a of the guide member 20 as a raceway surface, and comes into contact with a protrusion forming the guide surface 6a of the side plate 2 to prevent its rolling. The direction of movement is changed, and as described above, the coins roll toward the coin sorting section 8A, and only regular coins are sent to the storage side.

Also, coins inserted from the other coin slot 7b
100 yen coin B is shown in Figure 3b, Figure 4b and Figure 5.
As shown in FIG. b, the guide surface 6a of the side plate 2 described above, and the guide surface 20b of the guide member 20
The coin is guided in the thickness direction of the coin through the coin track 6, which is formed on the left side of the substrate 1 in the figure.
It is sent by rolling on the side.

Here, as is clear from FIG. 5b, the track portion that guides the 100 yen coin B in the thickness direction of the coin is formed with a distance that is sufficiently larger than the thickness of the coin, and this 100 yen coin B It is constructed to allow for smooth guidance. Therefore, in this part,
As shown in FIG. 6, the scales may become clogged, but in this case, the clogged coin exerts a force on the guide member 20 in the direction of opening, which causes the side plate 2 to be opened by, for example, the hook operation of the handset. It can be released and returned at the same time by doing so.

According to the coin sorting device according to the present invention having the above-described configuration, the substrate 1 forming the coin tracks 5 and 6 is formed entirely of a synthetic resin material so that a step D is formed on both the left and right sides thereof. Furthermore, by forming the coin tracks 5 and 6 for different types of coins in each of the above-mentioned stepped portions in cooperation with the side plate 2 installed opposite to this, a part of both coin tracks 5 and 6 is aligned in the thickness direction of the coin. This has the advantage that the width of the coin in the radial direction can be reduced and the size of the coin can be reduced. Further, according to the present invention, since the guide member 20 is provided in the above-mentioned intersection so as to be freely openable and closable, the coins A and B from the coin input ports 7a and 7b arranged in parallel in the radial direction of the coins are respectively It is possible to properly and smoothly guide coins to each stepped portion of the substrate 1, and even if coins become jammed in this portion, they can be easily removed, which has a great practical effect.

Note that the present invention is not limited to the above-mentioned embodiments,
It will be easily understood that the shape and structure of each part can be modified and changed as appropriate. For example, in the above-mentioned embodiment, the case was explained in which the openable and closable guide member 20 was used to define the left and right coin tracks 5 and 6. Such a configuration is not necessary, and the guide member 20 can be fixed in advance at the intersection, or
Alternatively, a corresponding track portion may be formed integrally with the substrate 1 or side plate 2 side.

〔Effect of the invention〕

As explained above, according to the coin sorting device according to the present invention, the substrate that is disposed opposite to the side plate and forms the coin track that is continuous with the coin input slots of different types arranged in parallel in the radial direction of the coins is attached to the left side of the coin sorting device. , the right side parts are formed of synthetic resin material with steps in the thickness direction of the coin, and a part of each coin track formed on the left and right sides is formed three-dimensionally in the thickness direction of the coin. The guide members that form the track surfaces of each coin track are supported on both sides of the intersection between the base plate and the side plate so as to be rotatable in the thickness direction of the coin. Despite the inexpensive configuration, it is possible to secure the required track length for each coin track, reduce the width dimension especially in the left and right directions of the board, and downsize the entire device. The overall structure is simplified compared to the conventional one, and furthermore, since the guide member can be opened and closed, functional problems such as coins getting jammed in the coin track can be solved, which has great effects.
