The present invention relates to a coin sorting device used in each vending machine, game machine, etc. More specifically, the present invention has a novel sorting machine that can check the diameter, thickness and weight of coins at the same time.

Until now, the coin sorting device has the diameter and thickness and weight of the coin or the diameter and thickness of the coin at the same time after the surface plate where the coin inlet, return lever and return port and U-shaped return port are installed. There was a means to check.

For example, ABE U.S. Patent No. 4,376,480 (Korean Patent Publication No. 83-748) is provided with a coin inlet, a return lever, a return port, and a U-shaped return coin receiver on a surface plate. Coin diameter which has a movable side plate which forms a coin sorting passage between a surface plate and a fixed side plate fixed to this surface plate, and has two engagement plates spaced apart at intervals smaller than the diameter of the regular coin to be sorted on one side. It is configured to support the check sorter on the movable side plate, to fix the weight on the sorter, to form a thickness check groove on the ramp installed on the fixed side plate, and to push the movable side plate to the axis of the return lever. COIN SORTING DEVICE has been proposed to allow coins to be returned.

In the present invention, the diameter and weight of the coin could be checked together by having a diameter checker centroid for coin diameter, but the coin thickness had to be checked in the thickness check groove formed on the ramp installed on the fixed side plate, and the returned coin or In removing the negative coin, since the movable side plate supported by the sorter is made in the form of widening the installation interval with the fixed side plate by the return lever, the overall structure is relatively complicated, which leads to a large number of components and thus high manufacturing costs. In addition, the number of assembling processes increases, so that the productivity could not be increased, and the sorting time is relatively long because the sorting of coins is checked in the sorting machine and the thickness checking groove.

Therefore, when the coins are continuously put in a short time, the accuracy of the sorting is likely to be lowered, and the coins are stopped between the sorting means, thereby losing the sorting function itself.

In addition, it is difficult to control two engagement pieces that are separated by smaller intervals than the normal coin diameter sorted by coin diameter checker when the gap is changed by long-term use. There was a problem that was difficult to expect.

An object of the present invention is to provide a coin sorting device having a novel sorter that can simultaneously check the diameter and thickness and weight of the coin.

Another object of the present invention to provide a coin sorting device that is easy to adjust the installation interval of the check means in checking the diameter and thickness of the coin with the sorter.

Still another object of the present invention is to provide a forced return means for the negative coin, which can easily send negative coin to the negative coin return port between the selector and the input coin guide means, thereby increasing the reliability and operating efficiency of the separator and the overall structure. Is to provide a simple coin sorting device.

Directly below and below the sorter 36, a regular coin guide plate 62 inclined toward the rear is attached to the side plate 20b of the substrate 20 by welding or screwing, and inside the rear of the sorter 36. A negative electrostatic focusing guide plate 64 inclined toward the side is attached to the side plate 20b of the substrate 20 with a screw 66. A conductive return guide plate 68 extending toward the coin return hole 16 of the marking plate 10 is connected to the lower end of the negative coin focusing guide plate 64, and the return guide plate 68 before the movement is U at one end. The screw 70 is fixed to the front plate 20a of the surface plate 10 and the substrate 20 together with the female return coin receiver 18. A support pin 74 having one end fixed to the side plate 20b of the substrate 20 is provided with a lever 72 for returning a coin or removing negative coins under the coin input guide plate 22. The lever 72 is rolled up with a torsion coil spring 76 whose both ends are supported by the lever 72 and the front plate 20a of the substrate 20, respectively, and the lever 72 is a surface plate. (10) It is in contact with the head 14a of the coin returning pusher 14 which extends outward.

The lower end of the normal coin guide plate 62 is in contact with the switch operation arm 80 of the normal coin detection micro switch 78 fixed to the back plate 20c of the substrate 20.

Unexplained symbols A.A 'indicates normal coin, D.D' indicates diameter of coin, and T.T 'indicates thickness of coin.

The overall operating state of the coin sorting apparatus according to the present invention having such a structure is shown in FIG. 5 and the working state of checking the normal coin and the negative coin in sorting coins is expressed in more detail in FIG. 6 and FIG. It is.

That is, the selector 36 of the coin sorting apparatus according to the present invention sends the regular coin guide plate 62 or the negative coin focusing guide plate 64 while checking the diameter, thickness and weight of the coin to be inserted. While turning the switch operation arm 88 of 78) to improve to a normal coin box, or to the coin return port (16).

More specifically, as shown in FIGS. 3, 5, and 6, two taper screws are fixed at intervals narrower than the diameters of coins sorted on the sliding plate 38 by the coins fed to the sorter 36. (46a). In case of normal coin (A) corresponding to the check set value of diameter (D) and thickness (T) set to the tapered head spacing of (46b), the balance is achieved by the center weight (42a) (42b).
