Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a coin distribution mechanism that mechanically distributes three or more types of coins after electronically detecting the type of coin.

[Prior art]

2. Description of the Related Art In real-time bill payment devices such as public telephones that provide services using coins, a coin processing mechanism that can use three or more types of coins is desired for reasons such as increasing the utilization of coins held by users. As the number of types of coins used increases, instead of setting up a coin slot for each type and processing the coins, it is possible to input multiple types of coins from one slot and distribute the coins to tracks set for each type. Cumulative screening methods are advantageous.

In such a single-inlet, multi-orbit processing device, the methods of sorting the coins can be roughly divided into 1) a method of sorting into 9 using an electromagnetic magnet, and 2) a method of sorting using a sorting window.

However, in the former case, the power consumption increases and one circuit becomes complicated. There were drawbacks such as the larger size and higher price. In addition, the latter conventionally had poor reliability, and in order to improve this, the sorting window had to be made longer, and the sorting device had to be larger.

The disadvantages of the conventional sorting window sorting method will be specifically explained using FIG.

Three types of coins K (KIO, K100, K50) with different outer diameters are inserted into the coin input slot 1 while rolling on the inclined track 2, passing through the diameter sorting machine provided on the first coin transfer track 3. Approaching window 6. Coins KIO with a larger diameter than the diameter sorting window 6 pass through as they are, and small coins (K100.50) lose their support and fall toward the window, deviating from the first coin transfer trajectory 3 and thus being transferred to the second coin transfer. It falls into orbit 4. Since this coin falls down while traveling in the traveling direction, the diameter selection window γ of the second coin transfer track 4 must also be provided before the point where the coin falls. Then, the 100 passes through the large coin in the sorting window 7, and the 50 loses its support when it comes to the small coin, and falls towards the window.
Because it misses the coin, it falls onto the third coin transfer track 5. In this way, the diameter sorting window 7 of the second coin rolling track 4 must be provided offset from the diameter sorting window 6 of the first coin transferring track 3, and the diameter of the coin increases as the speed increases during rolling. It becomes difficult to sort through the sorting window, so in order to compensate for this, it is necessary to
The diameter sorting window 1 of the coin transfer track 4 must be made longer as shown in the figure. For this reason, the width of the coin processing device becomes long, resulting in a large size.

[Summary of the invention]

The present invention was made in consideration of the above-mentioned circumstances.
By creating a meandering coin transfer trajectory to change the direction of coin transfer and suppress the increase in transfer speed, the length of the diameter sorting window can be shortened, and the coin shaking mechanism can be made smaller, making it possible to downsize the coin processing device. This is what we provide.

Hereinafter, the present invention will be explained in detail based on the drawings.

[Embodiment] (Figure 2 is a schematic configuration diagram showing an embodiment of a coin processing device equipped with a coin distribution mechanism according to the present invention.
11 is a coin slot, and 11 is an inclined track on which a coin K (KlO, K100.K50) inserted from the coin slot 10 rolls. A coin detection device 12 detects whether a coin is a genuine coin K (KlO, K100, K50) based on its outer diameter, material, thickness, etc.; A coin removal mechanism 14 is provided to sort out KOs and remove them to the return track 13 side. 15.16 are regular coins K (K10. and 1
00. 50) are distributed to corresponding coin accumulation trajectories 18A and 18B for each type.

19.20.21.22 is the 1st. Second. 3rd and 4th
the first and third coin transfer trajectories 19
．． The diameter selection windows 15, 16 are respectively arranged in 21. The first coin transfer track 19 is the inclined track 1
1, but in order to reverse the transfer direction of coins K (KIO, K100°K50) rolling on the track 11, the angle of inclination is set to be reversed. The second coin transfer track 20 is arranged below the first diameter sorting window 15 to collect coins (K100, K
50), the rolling angle is set to the first
The coin transfer trajectory 19 is set and arranged to be opposite to the coin transfer trajectory 19. The third coin rolling track 21 is provided downstream of the second coin rolling track 20, and is used to transfer coins (K100, K
In order to reverse the rolling direction of 50) again, the rolling angle is set to be reversed 9, and below this rolling track 21, the fourth coin rolling track 22 has approximately the same rolling angle. The coins (K50) dropped from the second diameter sorting window 16 are guided to the coin accumulation track 18C.

Note that θ and n are the respective orbits 11, 13, 19, 20 mentioned above.
The transfer angle is 21.22° and may be the same or different.

Coin storage mechanisms 24A, 24B, and 24C are provided at the terminal ends of each of the coin storage tracks 18A, 18B, and 18C, respectively, and a coin return mechanism 25 is provided on each coin storage track 18A.
, 18B, and 18C.

26A, 26B, and 26C are accumulation confirmation devices for detecting the coin accumulation tracks 18A, 18B, and 18C in which coins K are accumulated; 27 is a passage information storage device that also serves as a drive device for each accumulation confirmation device 26A, 26B, and 26C; , 28 is the coin removal mechanism 14. Drive devices for the coin storage mechanisms 24A, 24B, and 24C and the coin return mechanism 25; 29 is a detection information storage device that also serves as a drive device for the coin detection device 12; 30 is a storage device for storing information on the type of coin detected by the coin detection device 12 and passing through the coin storage device; A determination device 31 is a control device for these devices, which compares the accumulated trajectory information of the coins confirmed in the information storage device 27 and determines whether or not the coins have been accumulated correctly.

With this device, the above-mentioned coin storage mechanisms 24A, 2
The coins stored in 4B and 24C are sent into a safe 32, and the coins returned by the coin return mechanism 25 are sent into a return slot 33. Further, the device of this embodiment can handle three types of coins K (KIO).

It is configured to sort out 100 yen coins (K100, K2O), and in the figure, KIO is a 10 yen coin, and K100 is a 100 yen coin.
Yen coin, 50 is a 50 yen coin, 18A is a 10 yen coin KIO coin accumulation trajectory, 18B is 100 yen coin
00 coin accumulation trajectory and 18C indicate a 50 coin accumulation trajectory for a 50 yen coin.

In the coin processing device having such a configuration, coins inserted through the coin input port 10 and transferred along the inclined track 11 are driven and detected by the drive/detection information storage device 29 under the control of the control device 31.
The coin detection device 12, which is driven by the oscilloscope, detects whether the coin is correct or not and the type thereof, and this detection signal is stored in the detection information storage device 29. Note that the direction of rotation of the coin is to the left. If a coin is detected as a fraudulent coin, the coin removal mechanism 14 driven by the drive device 28 measures the number of coins falling from the inclined track 2 to the return track 13 and returns the coin to the return slot 33.
will be returned to. The regular coins K (KIO, K100°K50) sorted by the coin removal mechanism 14 are on the inclined track 1
1 while rolling in the direction of arrow a.
Enter 9. Here, since the transfer direction of the coin Q is reversed to the right, the coin Q is decelerated and approaches the first diameter sorting window 15. In this window 15, 100 yen coins and 50 yen coins K100, which have a smaller diameter than the 10 yen coin KIO. Then, the coin 50 falls toward the window 15, deviates from the first coin transfer track 19, and falls downward into the second coin transfer track 20. Here, since the rolling angle is opposite to the first coin transfer trajectory 19, the transfer direction is reversed to the left. Therefore, the coin (K100.50) that was accelerated while passing through the first diameter sorting window 15 is decelerated on the second coin transfer track 20 and enters the third coin transfer track 21. In this trajectory 21, the transfer angle is reversed again, so the coin (K1
00. K2O) is further decelerated and passes through the second diameter sorting window 1
It's approaching 6. In this window 16, 100 yen coin
A 50 yen coin with a smaller diameter falls on the fourth coin transfer track 22K, and is stored in the appropriate outer coin storage tracks 18A, 18B, and 18C according to the diameter that matches the type of coin.

Coins KIO, K100, sorted by the first and second diameter sorting windows 15, 16. 50 is an accumulation confirmation device 26A driven by the passage information storage device 27.

The coin accumulation trajectory is confirmed by 26B, 26C and this information is stored in the memory 27.

Then, the information in the detection information storage device 29 and the information in the passage information storage device 2T are compared by the discrimination device 30, and if they match, the service continues as is. In normal use, they are surprisingly consistent. However, examples and processing in the case where they do not match due to some kind of trouble are shown below.

If a publicly available device using such a coin distribution method is not installed in the correct position and the angle of inclination of the track cannot be properly obtained, erroneous accumulation may occur. This erroneous accumulation can be detected by comparing with the discriminating device 30.
It is confirmed. In this case, the control device 31 can also operate the coin removal mechanism 14 using the passing information storage device 27 which also serves as a drive device to remove all coins that will be inserted thereafter.

Regarding the service, the service will continue with the amount of coins inserted before the erroneous accumulation as the limit, and each time a predetermined amount of service is provided, the coin storage mechanisms 24A, 24B, and 24C will be operated to store the necessary coins, and the service will be limited to the maximum amount of coins. When the number of coins is exceeded or the user terminates the service, the communication line is disconnected and the coin return mechanism 25 is operated to return the surplus coins.

FIG. 3 is a block diagram of a coin distribution mechanism showing another embodiment of the invention.

In the figure, A is a rounded track provided before the first coin rolling track 19, and B is a second coin rolling track 2.
C is a track having a roundness provided at the front stage of the third coin transfer track 21; The purpose of making the orbits A and C round in this way is to prevent the coin from bouncing around.

The operation of the overhang prevention portion B will be explained. Second
In the figure, the coins sorted by the first diameter sorting window 15 rotate rightward while increasing their speed. Since the coin that falls from this diameter sorting window 15 and collides with the second coin transfer track 20 has a transfer angle of the track 20 that is opposite to the first coin transfer track 19, there is a force that reverses the transfer direction. acts, and when the accelerated speed decelerates, an upward force acts. If the rolling angle of the second coin rolling track 20 is loose, the force with which the presser presses down 9 will also not be loose, and as shown in Figure 4, it will take a long distance and time for the coin to come to rest and the rolling angle to reverse. Therefore, there is a possibility that the coins may come into contact with subsequent coins that are additionally inserted and cause a coin jam. Therefore, by rounding the rolling angle of the second coin rolling track 20 such that the angle increases as it goes upward as shown in FIG. 3, it is possible to prevent the coin from rising.

FIGS. 5(a) and 5(b) show the above-mentioned diameter sorting window 15 (16).

Reference numeral 1 designates a pair of window members that form a coin passage 42 by facing each other with a predetermined interval, one of which is the window member 40.
extends downward from the lower end of the other window member 41 to form the diameter sorting window 15, and a slope 44a inclined in the direction of the diameter sorting window 15 is provided at a portion facing the lower end of the window member 41.
An inverted triangular recess 44 is formed, and below the recess 44 are integrally protruded protrusions 0 and 40A.
This constitutes a coin rolling track 19. The height from this coin rolling track 19 to the upper edge of the recess 24 is smaller than the diameter of the 10 yen coin KIO, and the height of the 100 yen coin is smaller than the diameter of the 10 yen coin KIO.

IO goes straight regardless of the window 15 as shown in Figure 6 (~).Next, 100 yen or 50 yen coin K100.
When the coin approaches this window 15, 100 yen and 50 yen coins with a smaller diameter than the height of the window 15 are placed with a 100. Due to the inclination angle (approximately 7 degrees) of the coin rolling track 19, the coin 50 begins to fall in the direction of the inclination angle using point D as a fulcrum, and deviates from the coin transfer track 19 to the lower track, that is, the second coin transfer track 20 ( (See Figure 2). As soon as the fallen coins reach the second diameter sorting window 16 guided by the N3 coin rolling track 21, they are sorted into 100 yen and 50 yen coins in the same way as the first diameter sorting window 15.
The coins are divided into 1 and 50 coins and accumulated in their respective coin accumulation tracks.

Hiko, all of the above examples show cases where coins are sorted by diameter using a diameter sorting window, but
It is also possible to sort not only the diameter but also the thickness, thereby further improving the mechanical sorting accuracy.

Furthermore, the present invention is not limited to the above-mentioned embodiments and can be modified in various ways. For example, as shown in FIG. In order to prevent coins from jamming, it is possible to reduce the surface tension caused by the coins, or, as shown in FIG. You may try to slow down the coins.

〔Effect of the invention〕

As explained above, the coin transfer mechanism according to the present invention is
Since the coin transfer path is constructed in a meandering manner, the speed of coins at the diameter sorting window can be greatly restricted. As a result, coins tend to fall into the diameter sorting window due to their own weight, and coins smaller than the predetermined diameter inevitably fall out of orbit. therefore,
Reliability is sufficiently ensured even if the sorting window is shortened, and the sorting fn
It is suitable as a coin processing device for communication service devices such as public telephones and instant payment type communication service devices.
