Description

The present invention relates to a coin sorting mechanism in a coin sorting device incorporated in a vending machine, a public telephone, a money changer, or the like.

[Conventional technology]

Conventionally, a coin sorting device is provided with a detection coil that electrically discriminates the material of a coin and a coin sorting mechanism on a coin sorting track, and a regular coin that is determined to be a true coin by the detection coil by this coin sorting mechanism is a coin. Pseudo coins, which are determined to be illegal coins, are led to the accumulation orbit and dropped to the coin return orbit to be returned to the return port. Such a coin sorting mechanism is generally composed of a sorting lever that is rotatable and that shuts off the normal coin sorting track, and a magnet that swings this sorting lever when a normal coin is detected and withdraws from the coin sorting track. ing.

[Problems to be Solved by the Invention]

By the way, since the magnet is excited by the coin detection signal from the detection coil and causes the sorting lever to rotate by suction, after the detection coil determines that it is a true coin, until the sorting lever is withdrawn from the coin sorting trajectory, It takes a certain amount of time. During this time, coins are rolling in the coin sorting orbit,
It is necessary to provide a coin passage length commensurate with this between the detection coil and the coin allocating mechanism, which lengthens the coin selection orbit and limits the miniaturization of the device itself.

Therefore, the present invention solves the problems as described above, can shorten the distance from the detection coil to the coin sorting mechanism with a simple configuration, and can reduce the size of the device, the coin sorting device in the coin sorting device. The purpose is to provide a minute mechanism.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a substrate and a side plate which are vertically installed and face each other in parallel to each other to form a coin sorting track, and a detection coil for discriminating the material of coins rolling in the coin sorting track. And a lever insertion hole provided on the substrate or the side plate near the downstream side of the detection coil,
A return window provided in the side plate or the substrate corresponding to the lever insertion hole for communicating the coin selection track with the coin return track, and a return window rotatably disposed outside the coin selection track and provided at one end thereof. The coin receiving part is inserted into the coin selecting track through the lever insertion hole, and the sorting lever is provided with a weak return habit in the direction in which the coin receiving part moves upward, and the other end of the sorting lever is normally placed from below. A magnet for receiving and attracting and holding the other end of the sorting lever by being excited by the detection signal of the regular coin determination from the detection coil, and the magnet for the pseudo coin determination in the detection coil. By maintaining the non-excited state, the distribution lever is rotated by the weight of a pseudo coin that is heavier than the return habit imparted to the distribution lever, and is rotated by the weight of the pseudo coin. The is intended to drop from the return window to coin return track.

[Action]

In the present invention, the distribution lever is attracted and held by the magnet when the detection coil detects a regular coin. Therefore, the regular coin rolls on the coin receiving portion of the sorting lever and is guided to the accumulation orbit. On the other hand, in the case of a pseudo coin, the sorting lever is not sucked and held by the magnet but is rotated by the weight of the pseudo coin, and the pseudo coin is dropped from the return window to the coin return track.

[Examples] Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 is a front view showing an embodiment of a coin sorting mechanism according to the present invention, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a view showing a returning state of a heavy pseudo coin. . In these figures, 1 is a substrate which is erected substantially vertically inside the apparatus, 2 is one side of the substrate 1, that is, side plates which are arranged substantially parallel to the track forming surface A at a constant interval, A coin sorting orbit 4 inclined by a required angle in the rolling direction (direction of arrow X) of the coin 3 is provided between the plates 1 and 2, and a coin slot 5 is formed at the upper right end of the substrate 1. ing.

On the coin sorting orbit 4, a detection coil 6 for electrically discriminating the material of the coin 3, a regular coin 3A selected by the detection coil 6, and a pseudo coin 3B are accumulated in a trajectory 7 and a coin return trajectory 8 A coin sorting mechanism 9 for sorting the coins is provided.

The detection coil 6 is a conventionally well-known one (e.g., Japanese Utility Model Publication No. 57-37242) consisting of a transmitting coil and a receiving coil that are arranged to face each other across the coin sorting orbit 4, and is connected to an oscillation circuit. When 3 A is turned on, the excitation signal is transmitted and the detection signal is transmitted.

The substrate 1 and the side plate 2 are provided with a lever insertion hole 10 communicating with the coin sorting track 4 and a return window 11 so as to face each other and on the downstream side of the detection coil 6 in the vicinity of the lever insertion hole 10 and the return window 11. Communicates with the coin return track 8 provided below the side plate 2. The accumulation track 7 is formed between the substrate 1 and the side plate 2 so as to be continuous with the coin selection track 4, and thus is deviated from the coin return track 8 in the thickness direction of the coin 3.

Now, the coin sorting mechanism 9 has an outer surface of the substrate 1,
That is, it is composed of a distribution lever 12 arranged on the surface opposite to the track forming surface A, and a magnet 13 which holds the distribution lever 12 by suction when the regular coin 3A passes. The distribution lever 12 is rotatably supported at its intermediate portion by a support shaft 14 provided on a plastic plate (not shown) arranged on the outer surface of the substrate 1, and one end of the distribution lever 12 is inserted through the lever insertion hole 10. The coin receiving portion 15 is formed by being inserted into the coin sorting track 4. The support shaft 14 is parallel to the substrate 1 and is inclined in the same direction as the inclination angle of the coin sorting orbit 4. The sorting lever 12
Is slightly shifted from the center of the lever 12 in the front-rear direction toward the coin receiving portion 15 side (L ₂ > L ₁ ), so that a weak turning habit in the clockwise direction of FIG. Is abutted and locked to the yoke 16 of the magnet 13, and in this state, is substantially orthogonal to the substrate 1, and the coin receiving portion 15 forms the same plane as the rolling rail 17 of the coin 3. The sorting lever
The turning habit of 12 is that the turning fulcrum is located at the center position in the front-rear direction (L ₁ =
L ₂ ) and the weights of the front and rear ends may be changed and given.

An opening 19 is formed above the lever insertion hole 10, and the opening 19 is closed by a guide cover 21 having a pocket 20. The lower end 21a of the guide cover 21 is bent inward at an appropriate angle, and the upper edge 22 of the sorting window 11 provided on the side plate 2 is at substantially the same angle in the same direction as the lower end 21a of the guide cover 21. It has been folded.

Next, the operation of the coin sorting mechanism 9 having such a configuration will be described.

The coins 3 inserted into the coin insertion port 5 are sorted by the detection coil 6 while passing through the coin sorting track 4.
At this time, when the detection coil 6 determines that the coin is a normal coin, it sends a detection signal to excite the magnet 13. Then, the distribution lever 12 is suction-held by the magnet 13. Then, the regular coin 3A passing through the detection coil 6 rolls on the coin receiving portion 15 of the sorting lever 12 and is guided to the accumulation track 7. At this time, since the distribution lever 12 is held by the magnet 13, it does not rotate under the weight of the regular coin 3A.

On the other hand, when the pseudo coin 3B is inserted, the detection signal is not sent from the detection coil and the magnet 13 is held in the non-excited state. Therefore, the distribution lever 12 is not attracted and held by the magnet 13, and when the pseudo coin 3B that has passed through the detection coil 6 is placed on the coin receiving portion 15, the spindle is supported by its weight.
As shown in FIG. 3, the coin sorting orbit 4 and the return window 11 are made to communicate with each other by turning counterclockwise about the turning center 14 as shown in FIG. Then, the upper edge of the pseudo coin 3B loses its support by the track forming surface A of the substrate 1 and falls into the pocket 20 of the guide cover 37, and is thrown into the coin returning track 8 through the sorting window 11. When the pseudo coin 3B is dropped onto the coin return orbit 8, the sorting lever 12 rotates clockwise in FIG. 3 due to the turning behavior due to its weight balance, and the other end 12b contacts the upper surface of the yoke 16 of the magnet 13. Then, it returns to the initial position shown in FIG.

It should be noted that an ultra-light pseudo coin made of plastic or the like cannot operate the sorting lever 12 and passes through the coin sorting mechanism portion. However, for such a pseudo coin, a conventionally known lightweight coin sorting mechanism ( For example, Japanese Utility Model Publication No. 53-15347) may be provided at the rear of the coin sorting mechanism 9 for sorting, and the coins may be returned to the coin returning track 8.

In the above embodiment, the lever insertion hole 10 is provided in the substrate 1 and the side plate 2 is provided.
Although the return window 11 is provided in the above, it may be reversed.

〔The invention's effect〕

As described above, the coin sorting mechanism in the coin sorting device according to the present invention is configured such that one end forms the coin receiving portion and the rotatable sorting lever that is inserted into the coin sorting track is inserted into the coin receiving portion. Is given a weak turning habit in the ascending direction, and the other end of the lever is supported from below by a magnet, so the magnet is excited by a detection signal from a detection coil when sorting regular coins, When the sorting lever is sucked and held, the sorting lever is only held in its initial position and is not rotated by the magnet, and thus the coin is moved by a distance corresponding to the time required for this rotation. The sorting mechanism can be brought closer to the coin sorting section side, which enables downsizing of the device.
