ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin sorting device, and more particularly to a coin sorting device of the type that includes a check member, generally referred to as a cradle, which has the function of nicking the diameter and weight percent of an input coin.

内に回動させながら前進させるよう構成されている。Generally, the cradle is pivotally attached to one of two parallel side plates that define the coin sorting device, and has two engaging pieces spaced back and forth at a predetermined interval that protrude into the passageway so that the inserted coins can be handled by the cradle. By engaging with the engaging piece of the cradle, the cradle loses its balance and rotates forward, causing the coin to move forward while rotating into the passage.

通過してしまう欠点がある。The above-mentioned cradle is a drop-type coin sorting device in which coins are inserted from the coin input slot located almost directly above the cradle and fall almost vertically between the two engaging pieces, and exhibit highly accurate diameter and weight percent nicking functions. However, in a front-type coin sorting device in which coins are input from a coin input slot provided on the top plate at an upper side position of the cradle, the kinetic energy of the coin when it engages with the cradle is reduced due to the pushing force during input. Because of the difference, there is a drawback that even a small diameter defective coin sometimes gets on the cradle and rotates due to its engagement with the front engaging piece and passes through as if it were a coin of the normal diameter.

本考案の目的は、上述したフロント型硬貨選別装置にク

It is characterized by having the following.

う構成する。30 is a small-diameter defective coin removal plate according to the present invention, and a fixed side plate 6
The upper end is pivotally supported by a pin 32 to a bracket 31 fixed to the coin slot 2, and the passage is directed from the coin inlet 2 through the inclined oblique guideway 15 to the cradle 10 so that the blocking part 33 hits the coins rolling in the coin sorting passage 8. 8 is constantly energized by a balance weight part 34 at a position protruding into the inside of the blocking part 3.
An inclined surface 35 and a lower end latching claw 36 are provided above and below the coin, and the outer circumference of the regular coin is inclined by appropriately selecting the height of the inclined surface 35 and the distance between the tip 15a of the inclined guide path 15 and the exclusion plate 30. A defective coin that can engage both the guide path 15 and the inclined surface 35 but has a smaller diameter than a regular coin is stuck at the tip 15a of the inclined guide path 15.
and the blocking portion 33 of the exclusion plate 30 so as to be able to pass downwardly.

その通過を阻止するよう構成する。In addition, by appropriately selecting the position and protrusion length of the lower end latching pawl 36, the defective coins passing downward between the tip 15a of the inclined guide path 15 and the blocking part 33 of the exclusion plate 30 can be placed in the cradle 1.
In addition, while a defective coin falls between the engaging pieces 11 and 12 of the cradle 10, it is prevented from engaging and riding on the engaging piece 11 due to its abnormal movement. The cradle 10 is rotated around a pivot pin 16 to engage the outer periphery of a defective coin attempting to pass through the passage 8 to prevent the coin from passing.

次に、上述の構成になる装置の作動を説明する。Next, the operation of the apparatus configured as described above will be explained.

先づ正規の直径の硬貨Ａ例えば１０旧硬貨が投入された
場合、この硬貨Ａは第３図に示す鎖線で示すように、硬
貨投入口２から案内路１５を経て案内路先端１５ａと排
除板３０との間に入り込む。First, when a coin A of a regular diameter is inserted, for example, a 10 old coin, this coin A passes from the coin insertion slot 2 through the guide path 15 to the guide path tip 15a and the removal plate, as shown by the chain line in FIG. It falls between 30 and 30.

先端１５ａと排除板３０との間隔Ｓが硬貨Ａの直径りよ

経て通過し、最後にクレードル１０の係合片との係合を
離脱し、回転しながら磁気装置に通過し、材質チェック
を受ける。Since the distance S between the tip 15a and the rejection plate 30 is smaller than the diameter of the coin A, the outer circumference of the coin A contacts the inclined surface 35 of the rejection plate, and the gravity of the coin A causes the rejection plate 30 to be directed outward from the passage. The coin A falls toward the cradle through the gap between the movable side plate 7 and the exclusion plate caused by the force applied to push it, and engages with both engaging pieces 11 and 12 of the cradle, thereby causing the cradle to close. The coin loses its balance and rotates forward, and during this rotation, the coin passes through the gap between the movable side plate and the removal plate, and finally disengages from the engagement piece of the cradle 10 and rotates. The product passes through a magnetic device and undergoes a material check.

。Next, for a coin B having a smaller diameter than a 100 yen coin, such as a 50 yen coin, its diameter D' is smaller than the distance S between the tip of the removal plate guide path and the removal plate as shown in FIG. The coin B thrown in by the force falls vertically along the path between the guide path tip 15a and the removal plate 30 along the blocking part 33, passes between the engaging pieces of the cradle, and enters the return chute.

落下して返却シュートに入る。However, even if the outer periphery of the rejected coin B hits the inclined surface 35 of the rejection plate 30, the coin B is simply repelled, and no push-opening force is generated due to the weight of the coin. It falls almost vertically along the blocking part 33 of the removal plate and enters the return chute.

きを阻止される。However, as described above, when the coin B passes between the retaining pieces 11 and 12 of the cradle 10, it moves abnormally and engages with the front engaging piece 11, causing the cradle to rotate. As shown in the figure, the coin B rides on the front engagement piece 11 and tries to fall down from the front engagement piece 11 into the path to the magnetic device at the final rotational position of the cradle 10, but the lower end of the exclusion plate The movement is prevented by the engagement of the blocking engagement claws 36.

上述したように、本考案によれば、正規直径の硬貨より
小径の硬貨が磁気装置に通過するのを確実に防止するこ
とができる。As described above, according to the present invention, it is possible to reliably prevent coins having a diameter smaller than a regular diameter coin from passing through the magnetic device.
