Description

The claimed utility model relates to devices for counting documents and for detecting fake documents.

Known devices for counting and processing documents, such as banknotes, are used for counting, checking, and stacking a stack of usually documents of only one type. Among such devices, there are devices that use analog comparison circuits to test individual electronic components that specify the offset of these comparison circuits to determine whether the optical and magnetic characteristics of the document fall within predetermined threshold values. (SU No. 720442, publ. 08/08/08)

A device for counting documents is also known, comprising a guide bar defining a guide surface for transporting documents. In this device, said guide surface for transporting documents has right, center, and left parts and it also has a right sensor located next to the right part of said guide surface for transportation and generating a corresponding signal in response to the presence of a part of the document in this right part, a central sensor, located next to the central part of the specified guide surface of the transportation and generating the corresponding signal in response to the presence of part of the document in this the central part, the left sensor located next to the left part of the specified guide surface and generating the corresponding signal in response to the presence of a part of the document in this left part, a digital device for sampling the signal of the left sensor, the signal of the central sensor and the signal of the right sensor to obtain their corresponding representative values and a programmable controller connected to a digital sampling device and programmed to receive the result of counting documents controlling als to control operation of the device, and status signals for monitoring the operation in response to the respective representative values. (RU No. 2144697, publ. 20.01.2001) The known device for counting documents is the closest to the proposed one.

For successful implementation on the market, universal document counters must have wider functionality: read and check

the authenticity of different types of currencies, giving visual summarized information about the number and values of counted banknotes, had the ability to detect errors and stop when an error was detected after an audio signal without entering a fake banknote into the result of the count.

The task to which the proposed utility model is directed was to expand the functionality of the counter and increase the reliability of banknote verification.

The technical result of the proposed utility model is to enable the calculation and accurate control of the authenticity of the three types of currencies.

According to the proposed utility model, the problem is solved as follows.

A banknote counter is proposed comprising a supply pocket, a guide surface for transporting banknotes, a receiving pocket, a plurality of sensors located on a guide surface for transporting banknotes, a control board, an engine power board and a keyboard for manually entering commands, the counter comprising a piezoelectric sound signal generator, connected to the control board for receiving a sensor signal that does not correspond to the voltage level in the memory cells and for supplying a signal to the power board by the control board the use of engines to turn them off and remove the fake banknote from the receiving pocket; The ROM of the control board includes memory cells of three currencies.

The claimed banknote counter is shown in the drawings:

Figure 1 - banknote counter with a sensor circuit;

Figure 2 - scan path of the passage of banknotes with sensors.

The banknote counter includes a supply pocket 1, equipped with a sensor 2, which notifies the control board 3 that the banknotes are stacked in the counter supply pocket 1, a guide surface 4 for transporting banknotes, a receiving pocket 5 with a sensor 6, which notifies the control board 3 that the receiving pocket 5 still had banknotes. On the guide surface 4 for conveying banknotes there are many sensors 7, 8, 9, 10, 11: 7 - optical density sensors on the left and right; 8 - ultraviolet sensor, 9 - magnetic sensors left and right, 10 - central magnetic sensor, 11 - infrared sensors left and right. The counter is equipped with a piezoelectric generator 12 of the sound signal 13, which is connected to the control board 3. The counter also contains a board 14 for supplying the motors of the feeding 1 and receiving 5 pockets and a keyboard 15 for manually entering commands.

The control board 3 receives signals from sensors 7, 8, 9, 10, 11 over a period of not more than 5 ms. If the signal from any sensor does not correspond to the desired voltage level, then the control board 3 stops the operation of the feed 1 and 5 receive pockets in no more than 20 ms. Thus, at a counting speed of 1,500 banknotes per minute (recalculation time of 1 banknote - 40 ms), the counter manages to stop precisely on the banknote from which the above sensors registered signals that do not correspond to the signals from genuine banknotes, and this banknote is lying on top in the 5th receiving pocket . At the same time, there is a signal to the piezoelectric generator 12 and an audible signal 13 is output. When such a banknote is detected, it is not recorded in the counting result. The ROM program 16 counters include the values of UV and MG detection levels for three areas of memory cells (three currencies RUB, USD, EURO). Each currency has its own values of UV and MG detection levels and, accordingly, their own voltage values. Therefore, when converting different currencies, the signal level is corrected, which should come from the UV and MG sensors on the control board 3, which allows you to more accurately check the currency. Before starting the conversion, you must set the currency type to be converted on the counter display 15.
