BG67461B1 - Banknote disinfection device - Google Patents

Abstract

The invention is intended for disinfecting banknotes that go to the cash-desk commercially, the banking sector and wherever money is handled (banknotes). According to Figure 1, the banknote disinfection device consists of an input opening (1) for inserting the banknote, under which a sensor unit (2) is located, and below it symmetrically to the axis of the input unit are arranged the first pair of guide rollers (3I and 3II), which move out the banknote to a pair of pad rollers (6I and 6II), soaked in a disinfectant solution. Above the two pad rollers are located the respective valve-nozzles (5I and 5II) mounted on the bottoms respectively of disinfectant tanks (4I and 4II), from which valves the solution trickles on the rollers (6I and 6II). After its disinfection, the banknote enters the banknote guide (7), which changes the direction of movement to 90 degrees, namely from vertical to horizontal, through the second pair of guide rollers (3III and 3IV) and the third pair (3V and 3VI) it falls between two heaters- heating coils (8I and 8II), behind which are positioned respectively two fans (9I and 9II). The warm air flow dries the disinfected banknote and it enters a cash box-hopper for disinfected banknotes (10), from where it can be put back into circulation directly.

Description

Field of technique

The invention is intended for the disinfection of banknotes that go to the cash register in the commercial network, in the banking sector and everywhere where money (banknotes) is handled.

Prior art

A banknote disinfector [1] is known, consisting of a tank, buffer rolls, a sensor, a pump, a tube for supplying liquids. A disadvantage is the presence of a pump for supplying the disinfecting solution, which is supplied in a vertical direction upwards to the drums. The lack of a temperature sensor for the banknote drying rollers can result in either a lower temperature that does not dry the banknote sufficiently, or a higher temperature that can damage the banknote.

Technical essence of the invention

The task of the invention is to create a disinfectant for banknotes devoid of these disadvantages.

The task was solved by creating a disinfectant for banknotes, from the upper end of which the banknote is inserted through an opening, which, with the help of guide rollers, is taken to two tampon rollers soaked in a disinfectant solution, between which the banknotes pass. The disinfectant solution falls by gravity onto the tampon rolls by means of regulating valve-nozzles located at the lower end of the disinfectant tanks and positioned above the tampon rolls. Banknotes thus treated with disinfectant are moved by a transport mechanism with a length and speed guaranteeing the time required for the viruses to die. At the end of the transport mechanism there is a fan and a heater (one at the top and one at the bottom) that blow the banknote with warm air to dry it before it enters the decontaminated banknote hopper.

Advantages of the invention

The advantages of the banknote disinfector are that there is no pump to supply the disinfecting liquid vertically upwards, and the supply is by gravity from the tank to the pads, therefore no pressure sensor is needed. Banknotes are dried using a jet of warm air with a constant temperature, which is a guarantee that the banknotes will not be damaged.

Explanation of the attached figure

An exemplary embodiment is shown in the attached figure 1, which is a general diagram of the banknote disinfector.

Example of implementation of the invention

According to the figure, the disinfectant consists of an inlet 1, under which the sensor unit 2 is located, below it symmetrically to the axis of the inlet unit 1 are located the first pair of guide rollers 3 ¹ and 3 ¹¹ , and below them also symmetrically to this axis are the pair of tampon rollers 6 ¹ and 6 ¹¹ are installed, and one of the corresponding valve-nozzles 5 ¹ and 5 ¹¹ is located above each one. The latter are mounted on the bottoms of the respective disinfectant tanks 4 ¹ and 4 ¹¹ , and under the buffer rollers 6 ¹ and 6 ¹¹ is the banknote guide 7, which is bent at 90° in order to change the direction of movement of the banknote from vertical to horizontal , and between the second ^3Ш and ^3IV and the third pair of ^3V and ^3VI guide rollers is the other part of the banknote guide 7, and after the last pair of guide rollers rheotans-heaters 8 ¹ and 8 ¹¹ are symmetrically installed, as behind each of these are the corresponding fans 9 ^I and 9 ^II , after which a hopper cassette for the disinfected banknotes 10 is located.

Banknote Disinfector Action

The banknote is fed through the inlet 1, which activates the sensor unit 2, which sends a signal to drive the guide rollers 3 and the tampon rollers 6. The disinfection solution in the tanks 4, through the valve-nozzles 5, falls by gravity onto the tampon rollers 6 , irrigates them and maintains their humidity to the required degree. Thanks to the pairs of guide rollers 3, the banknote passes through the tampon rollers 6, which also rotate in the corresponding directions and at the corresponding speed, is disinfected and through the banknote guide 7 falls between the heaters 8. The jet of warm air created thanks to the fans 9 dries the disinfected banknotes that fall into the hopper cassette 10. The decontaminated banknotes in the cassette can immediately be used again in circulation.
