Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a coin sorting device used in vending machines, money changers, etc.

<Prior Art> Currently, there are three types of coins that can be used in various vending machines: 10 yen, 50 yen, and 100 yen coins, and their outer diameters are increasing in the order of 50 yen, 100 yen, and 10 yen. The coins are sorted by detecting subtle differences in their outer diameter, electrical characteristics, coefficient of repulsion, mass, etc.

<Problems to be solved by the invention> However, since the current coin sorting device is configured to handle the three types of coins mentioned above, it will be difficult to detect when new coins such as 500 yen, 1000 yen, etc. are issued in the future. cannot be dealt with at all, and in such a case there is an inconvenience that the entire sorting device must be replaced. The present invention attempts to solve such problems.

<Means for solving the problem> A coin passage made of a non-magnetic member is partitioned by a ferromagnetic member to form two coin passages, and an inserted coin is directed to one of the two coin passages according to its diameter. The present invention is characterized in that a means is provided for guiding the coins into the coins, and a magnet is disposed on the outer wall surface of each of these passages made of a non-magnetic material, so that the coins passing through the passages are magnetically sorted.

<Function> In this way, the coin passage composed of a non-magnetic member is partitioned by a ferromagnetic member to constitute two coin passages, and the inserted coin is guided into one of the two coin passages according to its diameter, By disposing magnets on the outer walls of both passages made of non-magnetic material and forming magnetic field passages in these two passages with ferromagnetic members as boundaries, the coins rolling through each passage are magnetically applied. A braking force is applied to the coins, and the braked coins are ejected from this passage and then hit against a deflector to be sorted.

<Example> The present invention will be described in detail below based on an example of the accompanying drawings.

In FIG. 1, the coin sorting device 1 is configured such that a side wall plate 2 and side wall plates 3 and 4 face each other at a predetermined interval to form a coin passage 5. 2 (shown by a chain line in FIG. 2). By making it openable in this way, maintenance and inspection are facilitated. On the inside of the side wall plate 3, there is a flange 3b,
3c is provided at an angle as shown in the figure, and the coin passage 5
It forms a rail.

Additionally, a slit 3 is provided above the flange 3b of this side wall plate 3 for sorting the outer diameter of the inserted coins.
d (Fig. 3b) is provided. The distance h of this slit 3d from the rail 3b is slightly larger than the outer diameter of a 10 yen coin.

On the other hand, a hole 2b is provided in the side wall plate 2 at a position facing the slit 3d, and a lever 8 (FIGS. 2 and 3
Figure a) is made to protrude. This lever 8 is rotatably supported by a pin 9 (FIG. 2) and is supported by a spring 10.
(FIG. 3b), a biasing force is applied so as to push into the passage 5.

Further, in the latter half of the coin passage 5, a partition plate 6 is disposed at an intermediate position of the passage 5 in parallel with the side wall plates 2 and 3 to partition the passage 5, and divides the passage 5 into two coin passages 5a and 5b.
form. The partition plate 6 is made of a ferromagnetic material, such as an iron plate. In addition, each coin passage 5a, 5b
It goes without saying that coins can freely pass through the

Coin passages 5 are provided at predetermined positions on the side wall plates 3 and 2, respectively.
a, 5b and the magnet 2 facing the partition plate 6.
0,21 are attached. These magnets 20 and 21 cooperate with the partition plate 6 to close the passage 5.
A braking force according to the material is applied to the coins passing through a and 5b, and the coins are sorted by determining the material.

Further, the side wall plate 3 is provided with an undersize slit 3a at a predetermined position below the coin receiving opening 1a and above the rail 3b. The size of this undersize slit is slightly smaller than the minimum diameter of a coin that can be used (the outer diameter of a 50 yen coin).

On the other hand, the undersize slit 3a of the side wall plate 2
A slit 2a is provided at a position facing the slit 2a, and a pin 12 bent into a substantially crank shape projects into the passage 5 from the slit 2a. This pin 12 is held in the state shown in FIG. 3a by a weight (not shown).

Now, if the outer diameter of the coin 30 that has fallen into the passage 5 from the coin receiving port 1a of the coin sorting device 1 is smaller than a 50 yen coin, it will be pushed out of the passage 5 from the undersize slit 3a by the pin 12. (Fig. 3a), and is led to a return port (not shown). The accepted coins 30 having an outer diameter larger than a 50 yen coin descend on the rail 3b. And this coin 3
If the 0 is a 50 yen, 10 yen, or 100 yen coin, it is pushed into the slit 3d by the lever 8 and guided into the coin passage 5a on one side of the partition plate 6. (Figure 3b). Also, if the coin 30 is larger than a 10 yen coin, it cannot enter the slit 3d.
It descends on the rail 3b against the biasing force of the lever 8, and is introduced into the coin passage 5b on the other side of the partition plate 6 (FIG. 3c).

In this way, the current 10 yen, 50 yen
Three types of coins, yen and 100 yen, and coins with an outer diameter larger than a 10 yen coin are separated by outer diameter.

Next, the magnet 20 or 21 applies a braking force to the coin passing through the passage 5a or 5b depending on the material. The coins that have passed through these passages 5a or 5b are ejected from the tip of the rail 3c. At this time, a coin such as a 10 yen coin to which a large braking force is applied by the magnet 20 comes off the rail 3c and immediately falls downward (in the direction of arrow F in FIG. 1). Also, for coins such as 50 yen and 100 yen coins that do not require much braking force, rail 3
After falling off from C, it flies a certain distance and falls, hitting deflector 7 (first and second) and following arrow E in Figure 1.
Or it will be bounced back in the E′ direction. The flight distance at this time varies depending on the material of the coin.

The coins falling in the directions of arrows E, E', and F are respectively guided to the next sorting section (not shown).

In this way, the outer diameter and material of the current three types of coins and coins are determined.

It goes without saying that if the coin passage 5b is not used, the magnet 21 need not be attached to the passage 5b.

<Effects of the invention> As explained above, the coin passage of the coin sorting device made of non-magnetic material is partitioned with a ferromagnetic member to form two coin passages, and the coin passage is divided into two by one partition plate. By installing a magnet on each of the outer walls of the passageway and using the partition plate as a keeper for both magnets, it is possible to handle the continuous insertion of many types of coins. If this happens, it can be dealt with by simply changing the route. In addition, by sharing a partition plate as a keeper for the front and rear magnets, it is possible to configure a magnetic field path in the front and back as desired. It has advantages such as being smaller and simpler than those arranged vertically or front to back, requiring fewer parts, and reducing costs.
