Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a coin sorting device, in which coins of various mixed denominations are conveyed one by one to a coin sorting section and the denominations discriminated by a discriminating section are collected. It relates to devices that classify by type.

[Technical background of the invention and its problems] In general, this type of coin sorting device continuously sends out coins of various denominations to a coin sorting path using a rotating disk, etc. A conveyor belt provided above the coin sorting passage transports the coins, and the coins transferred by the conveyor belt are placed in the coin sorting passage in the order of decreasing diameter. The structure was such that coins were sorted by dropping them through a sorting hole that was sized according to the size of the coins. However, in conventional devices, the sorting holes for sorting coins must be formed in order from the smallest diameter coin to the largest diameter coin, and the sorting order cannot be changed. Valid coins must be rejected through the exclusion hole formed at the most upstream side of the coin sorting passage, and invalid coins with a diameter larger than the largest suitable coin must be rejected through the exclusion hole at the most downstream side of the coin sorting passage. However, the removal of invalid coins by diameter could only exclude coins smaller or larger than the diameter range of various suitable coins, but could not exclude invalid coins with intermediate diameters.

Furthermore, in this conventional device, coins are sorted by diameter using a sorting hole, so coins made of inappropriate material cannot be eliminated. For example, coins that have been crushed and have a larger diameter are sorted using the sorting hole to be sorted and another sorting hole of the appropriate diameter of coins corresponding to the enlarged diameter. It has certain drawbacks.

[Object of the Invention] The present invention was made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a coin sorting device that can reliably classify various coins by type and also can arbitrarily set the sorting order.

[Summary of the Invention] The coin sorting device of the present invention includes a coin supply section that supplies coins one by one, a discrimination section that discriminates the denomination of each coin supplied from the coin supply section one by one, and this discrimination section. a linear coin sorting path that is continuous with the coin sorting path and guides the bottom surface of the coins; a conveying means that is provided above the coin sorting path along the coin sorting path and conveys the coins in contact with the top surface of the coins; a plurality of elongated holes provided in the coin sorting passage at appropriate intervals and formed obliquely with respect to the coin conveyance direction;
