Description

Description: TECHNICAL FIELD The present invention relates to sorting of coins in a coin processing machine such as coin packaging and counting.

(Prior Art) Conventionally, as this kind, there is one disclosed in Japanese Utility Model Publication No. Sho 56-88380. This prior art is based on a “introduction opening capable of introducing all the coins regardless of the diameter of the coins sent from the rotating disk, and an inclined surface that contacts one end of the large-diameter coin and makes the coin oblique to the sorting hole side. And a sorting path having a sorting hole curved at a curved portion, wherein the oblique large-diameter coin is eliminated in the sorting hole at the curved portion. However, there were many problems.

(Problems to be Solved by the Invention) The above-described device has a coin passage as a structure into which all coins can be introduced, and a sorting passage set to a set coin diameter in communication with the coin passage. The coin has a slope on one side, and the passage has a curved part. If the coin is larger than the set coin diameter of the coin introduced from the coin passage, a part of it will ride on the upper inclined surface and will be sent as it is by the feed belt and the sorting passage And the small coin is dropped and removed from the sorting hole in the sorting passage.

In such a case, large-diameter coins are to be eliminated by one sorting passage, so that the passage becomes long and the size of the fuselage is increased, and a curved portion tends to cause an uneven portion of the passage width. In some cases, the removal of coins became uncertain, or even large coins were sent while riding on one side of the passage and did not fall into the sorting hole.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin processing machine sorting device that can reliably remove coins other than a set coin by a simple operation without increasing the size of the coin processing machine.

(Means for Solving the Problems) An object of the present invention is to provide a rotating disk for sending coins toward a coin introduction port, an exclusion passage formed by an exclusion guide member and a guide plate, and an exclusion path for setting coins. A part of a large-diameter coin having a diameter larger than the diameter is ridden, and an exclusion inclined surface for guiding the large-diameter coin to a large-diameter coin exclusion hole in the direction of the extension of the exclusion passage, a set coin and a small diameter smaller than the outer diameter of the set coin A reject guide member provided with a lead surface for guiding the coin by changing the direction of the coin by approximately 90 ° with respect to the direction of the reject passage, wherein the interval between the reject guide member and the guide plate is the outer diameter of the set coin. An exclusion passage that can be adjusted to an interval corresponding to the above, a conveyance belt that conveys the inside of the exclusion passage while pressing a coin introduced from the rotating disk into the coin introduction port from above, and the exclusion of the exclusion passage. The guide member A sorting passage formed by a pair of sorting guides provided along a surface guiding direction, wherein the pair of sorting guides can support both end edges of the set coin, and the small-diameter coin can fall from between the set coins. A sorting path in which the interval between the pair of sorting guides can be adjusted to an interval corresponding to the outer diameter of the set coin, a feed belt that conveys the set coin through the sorting path, and the elimination guide member. This is achieved by a sorting device for a coin processing machine having an interval adjusting means capable of adjusting the interval between the pair of sorting guides and the interval between the pair of sorting guides.

(Operation) According to the present invention, large-diameter coins are eliminated by the exclusion passage, and small-diameter coins are eliminated by the sorting passage, so that coins other than the set coin can be reliably eliminated. In addition, the sorting passage becomes unnecessarily long, and the coin processing machine can be prevented from being enlarged. Furthermore, since the distance between the elimination guide member and the guide plate and the distance between the pair of sorting guides can be adjusted and linked by a single means called the distance adjusting means, only the set coin can be adjusted with a simple operation. It becomes possible to sort.

(Embodiment) Next, a detailed description will be given based on the drawings shown as an embodiment of the present invention.
