Introduction of paper money device and coin device in vending machine

Vending machines have been around for many years. The basic payment method is cash payment, including paper money and coins. We call it currency recognizer or cash module. It can be said that cash module is one of the basic core components of vending machine. Its main function is to identify the type, authenticity, and face value of the cash input, and it can be classified into a cash box or change according to the face value and type. Its working principle is to accurately feed the received cash type, denomination and other information to the brain of the vending machine on-board microcomputer in a timely manner. If the amount received is the same as the price of the product, the vending machine will be shipped. If the amount received is less than the price of the product, the vending machine will show that the coin is insufficient and prompt the customer to continue to insert the coin. If the amount received is greater than the price of the product, and the customer does not continue shopping after the vending machine is shipped, if the customer chooses to find change, The control computer of the vending machine calculates the difference between the amount and the selling price, and transmits the amount information that needs to be changed to the cash module, and the cash module performs the change according to the instruction information. It seems a very simple function, but it is very troublesome to achieve high requirements. Take the identification of authenticity as an example. The coin machine is better. It can be easily identified by measuring the diameter, thickness, electromagnetic characteristics, infrared characteristics, and mechanical vibration spectrum of the coin. Generally, there is no fold in the coin, and the error rate is almost Is zero. The more challenging thing is to identify banknotes. Everyone knows that banknotes are easy to wrinkle, get dirty, and break, which brings great challenges to fast and accurate identification! In order to make the cash module work better, usual maintenance is essential. The dust in the cash module of the vending machine needs to be cleaned regularly, and the currency stock in it is regularly checked. Although with the popularization of mobile payment, cash payment has become more and more tasteless in the unmanned vending machine industry, but some special places such as some primary and secondary schools do not encourage students to use mobile phones, and cash payment still occupies the mainstream status.
