Abstract

DEVICE FOR CELL DESTRUCTION IN CASSETTE ATMS The present invention refers to a device (8) that installed inside a cassette (1) of banknotes (9) of ATMs or ATMs, has the function of incinerating the banknotes (9) by precipitation of the molten material on the banknotes (9), material that comes from the exothermic chemical reaction of the Thermite type, causing the partial or total burning of the banknotes (9). The reaction starts from the moment an attack on the ATM energizes (1 O) the device (8).

Description

[001] The present invention aims at a security device (8) installed internally in each bank cassette (1) of self-service ATMs, and aiming to produce the incineration or partial or total destruction of the banknotes (9) contained in these cassettes ( 1) in the event of an attack or attempted robbery.

[002] Currently there are several solutions on the market for this purpose, some of them use a banknote inking system, others use a pyrotechnic device that launches fire on the banknotes, as described in a US patent 8631748. The problem with these solutions is, in high cost and difficulty in incinerating and inking the banknotes because they are pressed inside the cassette, which reduces the chance of ink and fire reaching a large area, and also because there is not enough oxygen for incineration.

[003] Priority BR 1015671-2 reveals a system of destruction by burning banknotes contained in ATMs when violated. This system is comprised of a metal capsule installed inside the ATMs that contains a pyrotechnic device ignited by an electric detonator. The electrical energy required for this ignition reaches the detonator through the coupling of the four-connection female socket.

[004] The document BR 1102250-7 describes a system to disable, by burning, the banknotes contained in the cassettes of ATMs when they are violated with the use of explosives triggered by the shock wave originated from the explosion.

[005] US 8631748 B2 relates to an intracassette security device for banking equipment mounted under the cover of a cash storage cassette that includes a main block equipped with cavities filled with pyrotechnic material, which can be lit by a wick driven by a filament electrically powered by the cassette circuit.

[006] Finally, reference WO 01/29786 describes a banknote cassette for use in an automatic teller machine provided with a plurality of sensors and a plurality of security devices, wherein a central controller responds to the sensors to trigger the security devices. security depending on the cassette situation.

[007] These documents have disadvantages in that they fail to provide a device installed on the inner face of the cover, in which the objective is not to throw a flame produced in the device over the banknotes, but to pour molten incandescent material and burn the banknotes.

[008] Inside the device (8) according to the present invention, which externally can be a metal, ceramic, plastic box, or others, there is internally an exothermic solution that does not depend on oxygen to maintain the reaction, of the TERMITE type (Thermite), or similar with nano thermite, Thermate , realize that these reactions do not need oxygen in the environment to react, and in addition, depending on the materials, they reach very high temperature beyond 1000 degrees, having high stability, thus giving safety to use. that is, it does not start the reaction spontaneously. As a non-limiting example, a reaction of this type using Fe2O3 and Al after starting (thermite), produces molten iron at 1530 °C which is poured through the slot (11) onto the banknotes (9). Not necessarily to have this reaction is necessary to use these compounds described in the example, several others react forming molten material but under different conditions. In addition to the exothermic solution, the device (8) must have a trigger for the reaction to occur, and for it to occur, it must be heated to a trigger temperature dependent on the chemical elements used in the exothermic compounds, and this trigger is a non-limiting example. it could be through a tape/magnesium grains wrapped in a copper wire that, when energized by a battery, makes the wire glow, doing the same with magnesium, which generates enough heat to ignite thermite-type components. If necessary, all the compounds in the solution can be vacuum sealed so that they maintain their characteristics over time and against moisture. The object of this patent can also be used by armored vehicles, security guards, treasuries, etc.

[009] Figure 1 shows an ATM cassette (1), where banknotes are placed internally (9), this cassette externally, normally has a lock (5) and a handle (4).

[0010] Figure 2 shows, when opening the cover (2), the base of the cassette (3), internally, which has rails and electrical or mechanical means that drive a guide (6), which when placed the banknotes (9 ) keeps them grouped together, making the banknote set (9) a rigid, pressed package.

[0011] Figure 3 shows where the device object of the invention (8) should normally be installed, that is, on the inner side of the cover (2).

[0012] Figure 4 shows the cassette (1) closed and internally containing the banknotes (9) and the device (8) installed.

[0013] Figure 5 shows the inner side of the cover (2) with the device (8) fixed on it, where it can be noted that there are 2 wires (10) that must be external to the device (8) and to the cassette (1), is energized so that it can initiate or trigger the reaction. Also shown in the device is a channel or slit (11) through which the molten material should precipitate on the banknotes (9), and this channel (11), in order not to leave the exothermic compound apparent, can have its opening closed by a material of thickness and brittleness, which only opens with the temperature of the reacting compound.

[0014] Figure 6 shows the cassette (1) internally, where on the banknotes (9) there is the molten material resulting from the exothermic and incandescent reaction (12) precipitated on the banknotes (9) causing the burning of these banknotes (9).

[0015] Figure 7 shows the Thermite formula using Fe(III) and Al, with a mass ratio of 25.3% Al and 74.7% Fe(III) but as an example, other formulations can be made, with other materials in order to intensify or reduce the effect, improve or facilitate the trigger, etc.

[0016] Figure 8 shows the device (8) installed in each individual cassette.

[0017] Figure 9 shows only one device (8) installed outside the cassette below or above the dispenser belt (14) inside the safe (13). In this case the result of the reaction, molten material (12), will precipitate from the first cassette (1) to the last cassette (1).

[0018] Figure 10 shows the device (8) installed external to each cassette (1).

[0019] As shown in the figures above, the "Device for destroying banknotes in ATM cassettes", in the form presented, can be constructed in several other ways, where the examples and figures cited and presented are by way of title of non-limiting example.
