Reconfigurable coin sorting machine based on stc89c51 microcontroller

Abstract

The invention provides a reconfigurable coin classifying collator based on an STCC single chip microcomputer. The reconfigurable coin classifying collator comprises a separator and a collator body, wherein one end of a tilted sliding plate is connected with a V-shaped coin leaking groove, a leaking through hole is formed in the middle of the tilted sliding plate, a turntable is arranged below the V-shaped coin leaking groove, rounded grooves are formed in the edge of the turntable, hole channels are formed below the turntable, and a blocking plate is arranged between the two hole channels. The collator comprises a base, a supporting plate is arranged above the base through four supporting columns, the supporting plate of the collator supports the separator, two steering engines are arranged on the bas, a columnar coin collector is arranged on each steering engine, and each columnar coin collector comprises four coin cylinders. The reconfigurable coin classifying collator can reduce the misjudgment rate of classified coins to some degree and improve the coin classifying efficiency by utilizing the tilted sliding plate leaking hole with a certain diameter, the V-shaped coin leaking groove, the rounded grooves formed in the turntable, the hole channels different in diameter, a motor driving the turntable to rapidly rotate and the like.

Description

technical field [0001] The invention relates to a coin sorting and sorting machine, in particular to a reconfigurable coin sorting and sorting machine based on an STC89C51 single-chip microcomputer. Background technique [0002] Compared with banknotes, coins are wear-resistant and easy to recycle, so they are widely used in the financial market. However, how to efficiently and conveniently sort coins after recycling has become a common concern of people. There are three main principles of coin sorting and counting mechanisms in the domestic and foreign markets. The first type of mechanism uses the eddy current method. The limited surface of the coin has textures. When the alternating magnetic field acts on it, irregular eddy currents will be generated. Lower, higher efficiency, but expensive, and poor anti-electromagnetic interference; the second type continuously vibrates the hopper with coins through the crank slider mechanism, so that the coins in the hopper slide onto t...

There are three main principles of coin sorting and counting mechanisms in the domestic and foreign markets. The first type of mechanism uses the eddy current method. The limited surface of the coin has textures. When the alternating magnetic field acts on it, irregular eddy currents will be generated. Lower, higher efficiency, but expensive, and poor anti-electromagnetic interference; the second type continuously vibrates the hopper with coins through the crank slider mechanism, so that the coins in the hopper slide onto the conveyor belt one by one, and orderly sent to the detection hole, and the cam mechanism drives the push rod to push the sorted coins out of the stepped hole to achieve automatic sorting of coins. This mechanism has strong anti-electromagnetic interference ability, but low efficiency and high misjudgment rate; the third category Under the action of vibration, the relationship between the thickness and diameter of coins is used to achieve the purpose of classification through restricted channels. Although the cost is low, the efficiency is low and the misjudgment rate is high.
