[Detailed description of the invention] [Field of industrial application] The present invention is a coin return mechanism that has a simple structure, can maintain sufficient strength of the substrate that forms the coin accumulation track together with the return flapper, and can be molded with synthetic resin. Regarding.

[Conventional technology]

Conventionally, the coin return mechanism of a coin sorting device is
The one disclosed in Japanese Utility Model Publication No. 58-6056 is well known. As shown in FIG. 1, this consists of a main plate 1, a sub-plate 2 and L that form a sorting passage 6 together with the main plate 1, which are disposed on the surface of the main plate 1 so as to be openable and closable.
a letter-shaped plate piece 3, the lower end of the plate piece 3 is rotatably supported on the back surface of the main plate 1, and the upper end protrudes into the sorting passage 6 through a hole 4 provided in the main plate 1. When storing coins, the plate piece 3 is rotated by an electromagnet 8 to move the rail portion 3a out of the sorting passage 6, so that the genuine coins fall into the genuine coin passage 7. It is composed of

[Problem that the invention attempts to solve]

By the way, in such a coin sorting device, in order to roll the coins stably, it is important to finish the surface of the main plate 1 facing the sub-plate 2, that is, the coin rolling side surface, into a smooth surface with no warpage and high precision. Therefore, in the past, the main plate 1 was manufactured from a metal plate and its surface was finished, but this type of metal main plate 1 not only increased the manufacturing cost but also became an obstacle to reducing the weight of the mechanism itself. . Therefore, recently attempts have been made to use resin for the main plate 1. However,
If the main plate 1 is simply made of synthetic resin and formed into a flat plate, distortion, warping, sink marks, etc. will easily occur during molding, and this will make it difficult to achieve flatness as a side wall of the rolling raceway, which will reduce the coin rolling speed. cannot be kept constant, and at the same time the coins meander in the direction of the coin trajectory, reducing the sorting accuracy.

Furthermore, not only was it not possible to obtain sufficient strength for the main plate, but it was also necessary to provide a large number of ribs to ensure flatness.

However, the provision of ribs not only complicates the shape and makes the mold manufacturing troublesome, but also increases the manufacturing cost.

It is also possible to reinforce the main plate with a separate member, but in that case there is a problem that the number of parts and the number of assembly steps will increase, and in either case, an increase in manufacturing costs is unavoidable.

Therefore, the present invention solves the above-mentioned problems and provides a coin return mechanism that has a simple structure, has high strength, does not require reinforcing members, etc., and makes it possible to reduce costs by using a resin substrate. The purpose is to

[Means for solving problems]

In order to achieve the above object, the present invention includes a flat board forming a coin rolling side surface, and a roughly U-shaped rail storage part provided on this board and having a recessed part for storing an accumulation rail so as to be able to come out and go out. The board and the rail storage section are integrally formed of synthetic resin.

[Effect]

The rail storage portion serves as a rib-like mechanism, increasing the strength of the board and preventing distortion and warpage.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 2 is a front view with the cover omitted of a coin sorting device equipped with a coin return mechanism according to the present invention, and FIG. 3 is a sectional view of the main part.

In these figures, reference numeral 10 denotes a flat plate-like substrate that forms the rolling side surface of the coin 15. This substrate 10 is integrally formed of synthetic resin and is inclined at a required angle toward the back side, so that the front side, that is, the coin Rolling side 1
Return flapper 11 arranged on the 0a side so that it can be opened and closed freely
Together, they form a coin sorting track 12 and a storage track 13. A coin input slot 1 is provided in the coin sorting track 12.
4, a determining section 16 electrically determines whether the coin 15 inserted from the coin 15 is genuine or false;
A rail 17 is provided to guide the vehicle, and a first return track 19 formed by the main plate 1 and the cover 18 is provided below the rail 17.

A storage rail 20 is disposed on the storage track 13 and stores a predetermined number of regular coins, for example, four coins 15a, 15b, 15c, and 15d, in the diametrical direction, as determined by the discrimination section 16. .
In this case, this embodiment shows an example of a coin sorting device that allows the use of multiple types of coins with different outer diameters. The storage rail 20 is a molded product made of synthetic resin, and is formed into a plate shape. A lever portion 20A extending to the back side of the substrate 10 is integrally provided on the back surface of the storage rail 20, and the lever portion 20A extending to the back surface side of the board 10 is integrally provided on the back surface of the storage rail 20. Substrate 10
A pair of shaft parts 21a and 21b rotatably held by a bearing part (not shown) provided on the surface of
are integrally protruded. Further, a recessed portion 2 is provided at a location corresponding to the storage rail 20 of the substrate 10.
A substantially U-shaped rail storage portion 23 having a shape of 2 is integrally formed with the substrate 10, and
The storage rail 20 is housed in such a manner that it can be freely retracted and retracted. In this case, the storage rail 20 is
Usually, its upper end protrudes from the recessed part 22 and faces into the storage track 13, and the return flapper 11
By being positioned near the lower end of the coin, the upper surface 20a constitutes a rolling and accumulating surface for the regular coins 15a, 15b, 15c, and 15d.
As shown in the figure, it is configured to retreat into the recessed portion 22. Then, during the return operation, the surface 20b constitutes the same surface as the surface of the substrate 10. Note that the lower part of the accumulation orbit 13 is the second
A return track 25 is formed. In addition, a sorting window 26 is formed approximately in the center of the return flapper 11 to allow the regular coins that are to be input and determined after accumulating a specified number of regular coins to overflow and fall into the second return track 25. A sorting flapper 27 is provided to control the opening and closing of this sorting window 26 and prevent continuous feeding.

A storage flapper 28 is provided at the end of the storage track 13 on the surface of the substrate 10 so as to be openable and closable, and a coin storage track 30 is formed below it. Note that 31 is a return rail that partitions the storage track 13, the coin storage track 30, and the second return track 25.

According to the coin return mechanism having such a configuration, the base plate 10 and the rail storage section 23 having the recessed portion 22 for storing the storage rail 20 during the return operation are integrally molded from synthetic resin. The rail storage portion 23 functions as a reinforcing member, and can increase the strength of the board 10. Therefore, there is no need to increase the thickness of the board 10, distortion and warping can be prevented, and there is no need for any reinforcing members such as ribs, so the structure is simple and requires a minimum number of parts. The substrate 10 can be manufactured at low cost.

Note that it is necessary to form a hole 36 in the wall body 35 of the rail housing section 23 corresponding to the lever section 20A of the storage rail 20, but this hole 36 is smaller than the size of the recessed section 22 as shown in FIG. Because it is small enough,
The strength of the substrate 1 is not affected. Also,
When the substrate 10 is made of synthetic resin instead of a metal plate, a return flapper 11, a storage rail 20,
Since the bearing parts for the storage flapper 28, the cover 18, etc. can be integrally formed at the same time, there is no need to separately manufacture parts such as bearing members, and productivity and assembly workability can be improved. Furthermore, during the return operation, the surface 20b of the storage rail 20
is formed on the same surface as the surface of the substrate 10, and the accumulated coins are allowed to fall along the surface 20b, so that the coins can be returned reliably. In addition, since the storage rail 20 is also made of a molded product made of synthetic resin, its shaft portions 21a and 21b can be formed at the same time when the rail 20 is molded.

[Effects of the invention] As explained above, the coin return mechanism according to the present invention integrates a flat board and a substantially U-shaped rail storage part that stores the storage rail so that it can come out and go out, using synthetic resin. With this structure, the rail housing portion can also serve as a reinforcing member and can sufficiently increase the strength of the board. Therefore, the manufacturing of the board is simple and inexpensive, and the practical effects are very large, such as making it possible to reduce the weight of the mechanism itself and to integrally mold the bearing portion, etc.
