A coin separator

Abstract

The invention discloses a coin separator, which comprises a frame, a screening disc assembly and a coin storage tray assembly. A centrifugal rotating mechanism is installed on the frame, and the screening disc assembly is installed on the centrifugal rotating mechanism and driven by it to rotate around the center of the frame. , the screening disc assembly includes a screening disc and a return structure, the return structure includes a spiral plate and an arc-shaped slide plate extending in the circumferential direction, the lower end of the spiral plate extends into the screening cavity and the top surface of the screen plate Fitting, the arc-shaped slide plate extends along the inner side wall of the screening tray, one end of the arc-shaped slide plate is located on the side where the spiral plate is not provided in the screening slot, and the other end of the arc-shaped slide plate is connected to the The upper end of the spiral plate is connected. In the present invention, during the screening process, coins are continuously added to the sieve plate and the coins that are not screened on the sieve plate are continuously sent back to the storage area from the spiral plate, and the coins can be circulated into the sieve plate for screening, and as many coins as possible are screened out. Both work efficiency and screening effect can be guaranteed.

Description

technical field [0001] The present invention relates to a coin separator. Background technique [0002] Coins are indispensable in our lives at present. Vending machines, bus rides, change in supermarkets and other occasions need to be used. However, coins collected in many occasions will be mixed together in large quantities. We must classify coins of different sizes and values. , but when the number of coins is large, manual sorting is inefficient, prone to errors, and cannot meet the needs. Although there are some automated coin separation devices, if the coins are separated one by one through the separation mechanism, although a variety of coins can be separated effectively, the coins must first be moved in a row or several rows, and the efficiency of conveying and separation is high. It is relatively low, so the separation of large batches of coins is usually achieved by batch screening and separation. However, when coins are screened on the screen, the number of coins...

Problems solved by technology

[0003] The purpose of the present invention is to provide a coin separator to solve the problem in the prior art that the number of coins screened is limited by the area of ​​the sieve plate, and the upper layer of the sieve plate will gradually become filled with coins larger than the sieve holes during the screening process. , must be transferred from the sieve plate and then screened, and when transferring coins, the coins that are smaller than the sieve hole on the upper layer will also be removed from the sieve plate, resulting in a problem that the separation efficiency is greatly reduced
