Description

PAPER MONEY COUNTING MACHINE HAVING A FUNCTION OF DISINFECTION AND DUST COLLECTION}

The present invention relates to a bill counter, and more specifically, dust and pulp dust generated in the process of counting bills are collected and the various bacteria on the bills are sterilized to enhance the usage environment of the bill counter. A bill counter has a sterilization and dust collection function.

In general, in financial institutions such as banks, post offices, securities companies, or companies that directly deal with a large amount of bills, or a government office, it is difficult and inconvenient to count bills by hand. I use it.

As shown in FIG. 1, such a banknote counter typically includes a counter-base 10, a banknote injection unit 12 provided on an upper surface of the counter-base 10, and a pair of rollers 14a rotating in opposite directions. and b) a conveying unit 16 which pulls and conveys the injected banknotes via the medium, and a display unit which displays the bill quantity by counting the bills conveyed along the conveying table 18 by the conveying unit 16 one by one. 20, and a discharging part 22 for transmitting the counted bills, and a seating part 24 in which bills discharged through the discharge part 22 are sequentially arranged and seated one by one, and injected The banknote injected into the unit 12 is counted as it moves through the above components.

However, the dust or bacteria adsorbed on the surface of the banknote or between the banknotes in the process of sending out the bills are removed from the bills and floated in the air in the process of being transported for counting. It is scattered by the blowing action of the discharge wing (26) to be released to the counter or the nearby workers working in the adjacent position to harm their health or pollute the room, and in severe cases deterioration of the chemicals applied during banknote production May cause odor by.

In recent years, various efforts have been made to overcome such problems, for example, Korean Utility Registration No. 1992-6046 "Friction paper money counter with dust and odor removing device"; 1993-5756 "Bill Counters"; No. 1999-172472 "dust collector for paper money counter" and Korean Utility Laid-Open No. 1999-26912 "Friction paper money counter with dust and odor removing device"; No. 2000-6706, a dust collector of a paper money counter, has been disclosed.

However, most of the disclosed prior arts are provided with a dust collector attached to the bottom surface of the counting base unit, which is not limited due to design, and thus the dust collection efficiency cannot be increased. Since only the filtration can be performed, dust of 0.3 μm or less, which is most harmful to the human body and has a high incidence, cannot be treated at all.

In addition, many of the prior arts described above are designed to collect only the dust generated during the counting, so that various bacteria adsorbed on the bills are left untouched, which directly inflicts direct harm on workers working near the counter. The disadvantage is that it can't be solved at all.

The present invention was created in view of the above-described problems of the prior art, and solves this problem. By arranging a plurality of filters appropriately, ozone is generated through an ozone generator to remove dust collected during counting of bills. Of course, the purpose is to provide a banknote counter having a sterilization and dust collection function that can be easily installed and used without being limited to the installation location while allowing to sterilize various bacteria.

In addition, the present invention provides a banknote counter having a sterilization and dust collection function that can also function as an air cleaning function while doubling the dust collecting ability of dust and bacteria by generating anion while also performing sterilization function of various bacteria by generating ozone. It is for.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a partially cutaway side view of the bill counter according to the present invention, Figure 3 is a side cross-sectional view of the main portion of the bill counter according to the present invention.

In FIG. 2, a through hole 110 having a predetermined size is formed in the rear wall surface of the counting base 100.

The dust collecting housing 200 having a space of a predetermined size is attached and fixed to the rear wall surface of the counting base 100 while sealing the through hole 110.

The dust collecting housing 200 has a structure in which one surface having a substantially rectangular box shape is opened and a plurality of exhaust ports 210 are formed on the open opposite surface.

A fixed flange 220 is formed on an outer edge of the open surface of the dust collecting housing 200, and the fixed flange 220 is fixed by bolts in close contact with the rear wall of the counting base 100 to collect the dust. The housing 200 is fixed to the counting base 100.

In particular, the intake fan 230 is fixed to the inside of the dust collecting housing 200 adjacent to the exhaust port 210, and the intake fan 230 is rotated at a high speed by a driving means such as a driving motor (not shown). 100, the inside of the air is sucked into the dust collecting housing 200 through the through hole 110 and then discharged into the atmosphere through the exhaust port 210.

The intake fan 230 is preferably provided to have a size corresponding to the through-hole 110.

According to FIG. 3, a prefilter 300, which is a primary filter, is detachably fixed to a front end side of the dust collecting housing 200, that is, a portion adjacent to the through hole 110, and an intake fan (from the prefilter 300) is removed. The charged electrostatic precipitating filter 400, which is a secondary filter including a charging plate 410 and a discharge plate 430, is spaced apart a predetermined distance toward the side of 230 and is separably fixed in the same manner as the prefilter 300. do.

The prefilter 300 is preferably composed of polyethylene or polypropylene resin having a mesh of 24 × 24 size and having an electrostatic property to adsorb coarse dust of 150 μm or more.

In particular, the pre-filter 300 is a filter for filtering the coarse dust after the LUPA, HEPA, MEDUME filter as a pre-treatment filter, it is usually used to filter the dust of 100㎛ or more.

As shown in FIGS. 4A and 4B, the charged electrostatic filter 400 has a structure in which a square plate-shaped charging plate 410 having a different shape and a discharge plate 430 are paired at a distance from each other. .

The charging plate 410 and the discharge plate 430 are a kind of electrode plate.

The charging plate 410 is formed with a plurality of polygonal outlet holes 422 through which the air inside the counting base 100 sucked by the intake fan 230 is discharged into the atmosphere, and the discharge plate 430 is discharged. A ball 432 is formed.

The outlet hole 422 has a substantially triangular shape and is formed in such a manner that both sides of the immersion 412 protruding from the surface facing the discharge plate 430 are opened, and the discharge hole 432 is a discharge plate. It is preferably formed in the form of a plurality of perforations in a circular shape with a predetermined size and interval over the entire surface of the (430).

The voltage applying means (not shown) is electrically connected to the charging plate 410 and the discharge plate 430. For example, the voltage applying means (circuit configuration related to the boosting) is an accommodating part (upper side of the dust collecting housing 200). It is preferably installed in 250).

The voltage applied to the charging plate 410 and the discharge plate 430 by the voltage applying means is a DC 7500 ~ 9500V, which is a silent discharge occurs only between 1000 ~ 10000V when the AC low voltage of 60Hz is converted into a DC high voltage Above 10000V, since oil discharge occurs and sparks are generated, the above-mentioned voltage of 7500 to 9500V that is capable of promoting ionization of air while being a voltage at which oil discharge does not occur is most preferable.

Here, in order to boost AC 220V of 60Hz to DC high voltage, the voltage magnitude and frequency can be stepped up by using switching device such as IGBT or MOS-FET such as PWM FULL BRIDGE INVERTER method which boosts DC 12V to high voltage. It is possible by employing a known PWM inverter method.

For example, FIG. 6 is a block diagram illustrating such an example. Referring to FIG. 6, a 60 Hz alternating current low voltage, for example, 220 V is converted into a direct current 12 V through a transformer, and then boosted to a direct current 7500 to 9500 V through a known high voltage transformer. One pole is connected to the charging plate 410, and the other pole of 7500 to 9500 V boosted through the 1,2,3rd bobbin coil is connected to the discharge plate 430 via a transistor and a diode circuit.

In addition, if a certain distance is applied while applying a high voltage between two opposing electrodes, a silent discharge occurs between the electrodes. At this time, part of the air located in the field of the silent discharge ionizes, and some causes ozone, while the rest Will cause negative ions. The higher the applied voltage, the higher the applied voltage, the higher the ozone generation rate and the lower the anion generation rate. As is well known, when the ozone and anion are lower than about 4500 V, the anion generation rate is proportionately higher and higher than that. It can be seen that the lower.

In this design, DC high voltage of 7500 ~ 9500V is used, so the result of experiment shows that the amount of ozone and anion generated within this voltage range is 3/3 and the amount of negative ion generated is 1/3 I could confirm it.

In particular, since ozone is harmful to the human body when a certain concentration is exceeded, when it has a concentration in the range of 0.01 ~ 0.05PPM, the sterilization power is doubled and the human body is not harmed at all.

Accordingly, in the present invention, by supplying air in an undischarged state to have such a concentration range, ozone is generated, and the contaminated air (fine air, fine air, etc. mixed air) inside the counting element 100 passes between the generated ozone. In a very short time, the dust and sterilization / sterilization operations are performed simultaneously.

In addition, for ease of discharge, the charging plate 410 and the discharge plate 430 is equal to or less than 1T, preferably aluminum 60 series having a thickness of 0.5 to 0.6T. This is because, in the case of the duralumin, aluminum is less likely to fall off, and thus the silent discharge can be easily induced without deformation of the charging plate 410 and the discharge plate 430 itself.

At the same time, when a DC high voltage is applied within a range in which no planetary discharge occurs, triangular phases are formed in the tip 412 protruding from one surface of the charging plate 410, so that the electrical density is high, thereby easily causing ionization of air. While increasing the negative ions, the negative ions charge the dust to the negative (-) to collide with the (+) charge to easily collect the fine dust in the range of 0.01 ~ 0.05㎛.

In addition, it has been found that the induced anions can perform an air cleaning function that promotes the body's fatigue recovery and blood circulation when maintaining approximately 200000 / cc. Therefore, in the present invention, the ozone and the negative ions are simultaneously generated and utilized to perform the air cleaning function while also performing the collection function; In order to maintain an optimal state, by additionally combining a known ozone meter or anion meter, it is possible to control and utilize the generation amount most harmlessly and advantageously to the human body.

In particular, the separation distance between the charge plate 410 and the discharge plate 430, which can be a silent discharge according to the voltage applied in the present invention is 10 ~ 12mm, the diameter of the discharge hole 432 that can occur the maximum collection capacity Is 6 ~ 10mm.

This is because the distance between the two plates causing the discharge is different according to the applied voltage, since the high voltage of 7500 ~ 9500V is applied in the present design, since the risk of planetary discharge is less than 10mm and no discharge occurs at 12mm or more. It is preferable to space apart the charging plate 410 and the discharge plate 430 within a range.

Similarly, the discharge hole 432 formed in the discharge plate 430 should also maintain the range of 6 ~ 10mm as described above only 0.01㎛ or more due to the action of the anion induced in the applied voltage, that is, the range of 7500 ~ 9500V This range is most suitable because it can collect fine dust.

The operation relationship of the present invention made of such a configuration will be described with reference to the above-described drawings and FIG.

According to FIGS. 2 to 5, when the bills are placed on the inlet for bill counting and counting is started, bills are conveyed by a pair of rollers rotating in opposite directions to be sent out to the seating part at the same time as counting.

In the counting process, dust or various bacteria that are buried or adsorbed on the banknote are dropped from the banknote surface and floated inside the counting base 100.

The intake fan 230 which is driven at the same time as the operation of the bill counter, inhales the air inside the counter base 100 at a constant suction pressure, that is, a suction pressure such that the wind pressure does not affect the counting of bills. The air is discharged to the atmosphere through the pre-filter 300, which is a primary filter, and the charged electrostatic filter 400, which is a secondary filter.

At this time, the pre-filter 300 is a primary dust collecting 150㎛ or more coarse dust, and the charged electrostatic filter 400 is a secondary dust collecting less than 0.3㎛, for example, 0.01㎛ or more.

In the dust collecting process, ozone and negative ions are generated by DC current of 7500 to 9500 V applied to the charging plate 410 and the discharge plate 430 through a voltage applying means (not shown).

Ozone is generated to have a concentration of 0.01 ~ 0.05PPM, which is not harmful to the human body, and at the same time anion is generated.

The ozone changes in electrical conductivity depending on the ozone sensor, that is, the concentration. It is preferable to control the ozone to maintain the above range by using a known sensor capable of real-time measurement by reading and digitizing the ozone.

Thus, the bacteria passing through the secondary filter are sterilized, and at the same time, the odors such as ammonia, acetaldehyde, cumulative and the like are deodorized. In addition, the collecting power of the fine dust by the negative ions is increased and the residual negative ions are released into the atmosphere by the intake fan 230 to clean the air in the room to feel a fresh feeling.

The collected dusts are removed by removing the dust collecting housing 200 from the counting base 100 at regular intervals and then reassembled or replaced with new filters to create a more pleasant and refreshing bill counter environment. .

As described in detail above, the present invention provides the following effects.

First, it can sterilize various bacteria adsorbed on paper money as well as removing dust and odors.

Second, dust can be collected even less than 0.3㎛ fine dust dust efficiency is significantly improved.

Third, it also possesses an air cleaning function by negative ions, which has the advantage of enhancing the usage environment of the bill counter.
