Description

A simple coin sorting and counting device

technical field

The invention belongs to the technical field of coin sorting and relates to a simple coin sorting and counting device.

Background technique

Nowadays, there are many kinds of coin sorting counters on the market, but most of them have some disadvantages, such as a small number of separated coins at a time, or even cannot realize the counting function at all, even so, the price of these coin sorting counters is still very expensive. Therefore, at present, most of the country still adopts the method of manual sorting and counting. This kind of manual sorting method of coins has a huge workload and high work cost, and it is generally not repeated after sorting, so the error produced is also very large.

The Chinese utility model patent with the authorized announcement number CN205038705U discloses an automatic coin sorter. The upper part of the coin automatic sorter body is provided with a funnel, and the lower part of the funnel is aligned with the conveyor belt. The end of the conveyor belt is provided with a slide rail, which is connected to the guide rail. Below the rails there are different coin collectors. In the technical solution disclosed in the above-mentioned patent, the automatic coin sorting machine can sort coins of different denominations and realize the counting function. The overlap phenomenon cannot guarantee that the coins will be transferred one by one, making it difficult for the coins to fall from the corresponding openings one by one when sliding up and down the guide rail, and the separation effect is poor; Passing through the opening without falling will affect the accuracy of separation, and it is prone to jumping during the sliding process, thereby further reducing the separation effect.
