Next, a method of assembling the coin sorting apparatus having such a configuration will be described. First, the convex piece 28 of the coin sorting plate member 25 is inserted into the opening 12 from the front side of the substrate 2 and is engaged with the rear side of the convex piece 13, and the convex piece 13 is used as a rotation fulcrum. When the coin sorting member 25 is rotated so as to fall down on the substrate side, the engaging pieces 29 are engaged with the ribs 14, and the coin sorting plate member 25 is fitted into the opening 12. At this time, the claw portion 30 passes through the opening portion 12 from the front surface side of the substrate 2 and elastically deforms and engages with the protruding ridge member 15. By the engagement, the separation of the coin sorting plate member 25 from the opening 12 to the front side is regulated, and by the engagement of the engagement piece 29 with the rib 14, the separation from the opening 12 to the back side is regulated. Therefore, the coin sorting plate member 25 fitted in the opening 12 is fixed to the substrate 2. The surface of the coin sorting plate member 25 fitted to the opening 12 and the surface of the substrate 2 are located at the same plane position because the thickness of the engaging piece 29 is formed to be the same as the thickness of the convex piece 13. The sorting rail 27 and the coin rolling surface of the coin rail 6 are connected to each other.

Thereafter, the bearing groove 36 of the flapper 35 is fitted into the shaft 31, and one end of the coil spring 33 is engaged with the concave portion 37.
A swing bias is applied to the coin sorting plate member 25 side around the shaft 31. The flapper 35 pressed by the coin sorting plate member 25 has three dowels 38 formed of the coin sorting plate member 25.
Is kept constant so that the distance from the coin sorting plate member 25 is slightly larger than the thickness of regular coins,
The flapper 35 forms a coin orbit with the coin sorting plate member 25 and the sorting rail portion 27. The coin sorting unit 24 composed of the flapper 35 and the coin sorting plate member 25 incorporated in this way is configured to perform an outer shape selection for selecting the outer shape and thickness of the coin.

Next, the operation of sorting coins in the coin sorting apparatus thus constructed will be described. Coin slot member 4
The coin C inserted from the insertion slot gauge 5 is selected by the insertion slot gauge 5 without being able to insert a pseudo coin having an outer diameter and a thickness larger than that of a regular coin. Of the coins that have passed through the insertion slot gauge 5, the lightweight pseudo coin C1 and the magnetic coin C2 are separated from the surface of the substrate 2 by the lightweight selection lever 8 and the magnet 11 in the thickness direction of the coin.
The coin is removed and guided to the coin return orbit 22. Here, the coins not removed fall on the rolling surface of the coin rail 6, roll along the rolling surface, and roll on the sorting rail 27 connected to the rolling surface. On the sorting rail 27,
The pseudo coin C3 whose outer diameter is smaller than the regular coin has its upper end fall into the sorting window 26 and is guided from the coin falling window 39 to the coin returning orbit 22. Further, the pseudo coin C4 having a thickness smaller than that of the regular coin loses the support between the sorting rail portion 27 and the lower edge 35a of the flapper 35, and like the pseudo coin C3,
The upper end falls down into the sorting window 26, and is guided from the coin falling window 39 to the coin return orbit 22.

The regular coin C5 that has passed through the coin sorting unit 24 is stored in the coin supporting portion 4 of the storage lever 18 and the flapper 35.
0, and are temporarily accumulated in the coin sorting unit 24 direction. When the storage signal arrives, the storage lever 18
Escapes from the coin orbit, and at the same time, the escape pin 16 advances into the coin orbit. Therefore, the lowest accumulated coin is guided to the coin storage orbit 21 and the second and subsequent accumulated coins are moved by the escape pin 16 to the coin orbit. Is prevented from rolling. When it is confirmed by the storage sensor 19 that the coin is stored in the coin storage track 21, the storage lever 18 advances into the coin track, and at the same time, the escape pin 16 retreats from the coin track. The regular coins C5 are supported one by one by the storage lever 18 and the coin support portion 40.

When the return operation is performed after the operation of the device is completed, the coin return operation portion 41 of the flapper 35 is pressed toward the substrate 2 by an interlocking rod (not shown) in conjunction with the return operation. The lower end of the flapper 35 is separated from the substrate 2 around the shaft 31 against the pressing force of the coil spring 33, the lower part of the coin orbit is opened, and the accumulated normal coin C5 is moved to the coin return orbit 22. It is led to.

Here, when the outer shape of the coin to be sorted, that is, the type of the outer diameter or thickness is changed, a coin sorting window 26 or a sorting rail portion 27 corresponding to the outer diameter and thickness of the new coin is provided. The flapper 35 in which the positions of the coin sorting plate member 25 and the dowel 38 are changed corresponding to a new coin
Prepare in advance. Then, the claw portion 30 of the coin sorting plate member 25 of the currently installed coin sorting unit 24 is elastically deformed to release the engagement with the ridge 15 of the substrate 2 and the coin sorting unit 24 is opened. Remove from Then, a new coin sorting unit including a coin sorting plate member and a flapper prepared in advance is inserted into the opening 12.
Fit and fix to.

As described above, even if the outer shape of the coin to be sorted changes, the entire board 2 does not need to be replaced, and only the coin sorting unit 24 which is a part of the board 2 needs to be replaced. Since the change of the mold to be manufactured is small, it is economical, the change period can be greatly shortened, and simply without changing the positional relationship with other components of the device main body for mounting the coin sorting device. Since only the coin sorting unit 24 needs to be attached and detached, the exchange becomes easy.

Further, since the coin sorting unit 24 which requires sorting accuracy can be manufactured separately from the substrate 2, the outer shape of the coin sorting plate member 25 with respect to the substrate 2 becomes small, so that the coin sorting Even if the plate member 25 is molded with a synthetic resin, the occurrence of molding distortion can be suppressed,
Since the sorting accuracy can be improved and the substrate 2 and the flapper 35 can also be made of synthetic resin, weight reduction can be achieved at the same time.

FIG. 4 is a perspective view of a coin sorting plate member according to a second embodiment of the present invention. In the second embodiment, the dowel 3 provided on the flapper 35 in the first embodiment described above is used.
8 is characterized in that it is provided as a dowel 42 on the surface of the coin sorting plate member 25. This utilizes the fact that the coin sorting plate member 25 is separated from the substrate 2 so that the coin sorting plate member 25 can be formed with high accuracy even if it is formed of a synthetic resin. Dowel 4
2 is integrally formed with a coin sorting plate member 25.

As described above, the dowel 4 is provided on the coin sorting plate member 25 side.
When the type of coins to be sorted is changed by providing 2, the flapper 35 does not need to be changed, but only the coin sorting plate member 25 in which the position of the dowel 42 has been changed according to the sorting window needs to be replaced. It is economical because it can be used in common.

[0024]

As described above, according to the present invention, coins inserted from an insertion slot are rolled by rails supporting the diametric direction and substrates supporting the surface direction, and the outer shape of the rolling coins In a coin sorting device provided with an outer shape sorting unit for sorting out, when the coin to be sorted is changed by unitizing the outer shape sorting unit to be detachable from the substrate, the outer diameter sorting according to the coin is performed.
