Background
At present, the requirement of banks in China on currency is higher and higher, the Renminbi can be circulated in the market only after being replaced by seven new RMB, and the task of clearing new and old RMB by banks is quite heavy.
With the development and progress of science and technology, the paper currency sorter is used as special sorting equipment for financial enterprises and professional banks, and completely replaces manual sorting. In the existing paper currency sorter in the market, the performance of the product is the best in foreign countries, but the structure is complex and the price is expensive. Although the price of domestic products is low, the design of the whole structure and the paper money moving mechanism is not reasonable, the common paper money moving mechanism has the defects of unsmooth paper money moving, easy paper money clamping, high noise, large volume, inconvenient maintenance and the like, the operation habit of domestic bank tellers cannot be adapted, the requirements of users are difficult to meet, and the popularization and the use of the paper money sorting machine are limited. And although the price of domestic products is low, the cost is not low relative to the lower price.
In addition, the continuous appearance of counterfeit money also puts higher demands on the banknote sorting machine. At present, a user mainly uses a currency counting and detecting machine to distinguish counterfeit currency, the traditional A-type currency counting and detecting machine in China adopts an image technology, the requirement on paper currency passing through the machine is high, false alarm and machine halt are easily caused, the use efficiency of an operator is not high, and the labor intensity is increased.

The electromagnetic plate turnover mechanism is arranged at the first banknote outlet.
The driving belt pulley is positioned below the driving wheel of the relay transmission wheel set, and the first steering belt pulley is positioned at the rear lower side of the driving belt pulley; the first driven belt pulley is arranged at the rear side of the first cash outlet, and the second steering belt pulley is positioned at the rear upper side of the first driven belt pulley; the second driven pulley sets up in second cash dispenser rear side, and cash dispenser belt pinch roller sets up in the preceding upside of second driven pulley, and the third driven pulley sets up below the second driven pulley back. The first belt tensioning wheel is positioned between the driving belt wheel and the first driven belt wheel, and the second belt tensioning wheel and the third belt tensioning wheel are positioned between the driving belt wheel and the banknote discharging belt pressing wheel.
The first flat belt passes through the lower parts of the second belt tensioning wheel and the third belt tensioning wheel to the uppermost end from the upper part of the driving belt wheel in an inclined manner, bypasses the banknote discharging belt pressing wheel to be folded back from the upper part of the banknote discharging belt pressing wheel, passes through the upper parts of the second driven belt wheel and the third driven belt wheel in sequence, passes through the space between the first driven belt wheel and the second steering belt wheel, passes through the upper part of the first tensioning wheel and then returns to the lower part of the driving belt wheel.
The second flat belt passes through the first driven belt pulley from the upper part of the first steering belt pulley, passes through the first driven belt pulley from the upper part of the first driven belt pulley, passes through the second steering belt pulley, passes through the second driven belt pulley, passes through the second tensioning belt pulley, and returns to the lower part of the first.
The third flat belt is sleeved on the second driven pulley and the third driven pulley.
The electromagnetic turning plate mechanism consists of a turning plate with two paper money guide surfaces and a turning plate swing driving device which are arranged in a swinging mode.
In the paper money sorter, the paper money feeding mechanism adopts a common paper money conveying wheel matched with a paper money twisting wheel to convey paper money.
As an improvement, for the paper currency sorter, more paper currency outlets can be added after the second paper currency outlet, and only the first flat belt is needed to be continued, and the fourth flat belt, the … … flat belt and the Nth flat belt are needed to be added. After the money outlet is increased, the sorting machine can be converted into a medium-sized or even large-sized sorting machine.
It is not difficult to think that the sorter can be completely used as a class A cash counter.
The invention has the following beneficial effects:
1. the paper money sorter can work continuously without stopping, can withdraw from a suspected money outlet when detecting suspected money or counterfeit money, and improves the use efficiency of a bank teller;
2. the machine is respectively driven by a main motor and an auxiliary motor, so that paper money entering the counterfeit identification channel can be effectively controlled, and no paper money is retained in the channel when the machine is stopped;
3. the invention combines a roller pressing type conveying mechanism and a belt type conveying mechanism. The belt type transmission mechanism is arranged behind the counterfeit identifying device, so that the counterfeit identification of the paper money has enough time for processing, the speed of the whole machine for processing the paper money is improved, and the highest speed can reach 1200 sheets/minute;
4. in the whole paper money transmission channel, the main transmission part adopts a belt transmission mechanism, the structure is simple, and the transmission is stable. The longest section of the transmission channel is only composed of two sets of flat belts, so that the number of belts and rollers of the whole machine is small, noise sources are effectively reduced, and the noise is low;
5. the paper money inlet mechanism, the suspected money outlet and the normal paper money outlet are positioned on the same side through twice turning of the paper money sorter, so that the single-hand operation can be realized, and the labor intensity of a bank teller is reduced.
For convenience of description, the side opposite to the money inlet of the machine is defined as front, and the side back to the money inlet is defined as back.
