Welcome to Hi-News.ru! First paper money appeared in China in 910 year — they replaced the metal bars. For a long time, the counting of bills can be done only manually, and only in 1908 in an attempt to optimize this process, the American engineer and inventor Charles Franklin Kettering invented the first electric currency counter. He quickly became popular with the development of technology has improved and acquired new features. How does modern money counter — this is in the news today!
All counters of banknotes are approximately on the same principle: using a system of rollers, the counter captures from the boot tray on one bill, holds it in the path and puts into the output tray. Passing through the tract, the bills block the light, and thus the system determines the number of them. Typically, the count rate may range from 600 to 2000 banknotes per minute. The simplest models can’t make anything but mechanical counting and rejection are stuck or torn banknotes that are very different in size.
More advanced counters can not only count notes, but also to check their authenticity. Automatic detection occurs at the moment of passage of the banknotes through the tract. The most simple detectors have only a single photo-detectors and scan only part of the image. More functional models examine the full image of the banknote, by using the photodetector line.
There are also counters of banknotes, which can accept notes not one, but a whole bunch. Such devices are divided into 2 types: roller-fractional, and vacuum. In the first case before the tract are rubber and polyurethane rollers, which drags the lower bill of the bundles in the path. To have the money included in the counter by one, over the entrance to the path are rollers which rotate in the opposite direction and push the extra bills back.
In the case of a vacuum meter the bundle of banknotes is pressed against the perforated tape, which creates a low pressure. Counting takes place right in the intercepted gum packs with vacuum heads, considering the corners of the bills. Vacuum devices have low noise and high accuracy.
The most advanced meters are scanning in visible, infrared and ultraviolet ranges, reads the magnetic marks, and measure the thickness of the paper mechanical or capacitive method. The latter feature allows to distinguish new banknotes from torn or stuck together, and sort banknotes currency, denomination, authenticity and fitness. In such cases, the counters have at least two trays for calculated cuts: basic and burn-in.
In addition to banknote counters there are mnogochislennye devices, often referred to as sorters of banknotes. They have three or more trays of sorted money, each designed for specific banknotes of the specified denomination. Some of these multifunction devices in addition to the detection of authenticity and sorting of more able and packaging bills.
