Abstract
A paper currency method and system, which is comprised of multi-stages of sections or areas for cleaning and/or sanitizing/and or drying with input and output to receive and dispense. A roller and conveyor, opposed to each other with pressure fluid or air jets, remove dirt, oils, and other foreign matter from the currency. When desired by the end user, the currency passes through a sanitation section using a sanitation solution to effectively kill viral and fungal organisms. After the cleaning processes is complete, the currency passes through a drying portion using squeezing rollers, high-pressure air and heat to remove moisture and to complete the reconditioning process.
Description
- The invention relates to a paper currency cleaning, reconditioning and sterilization system and associated methodology and more particularly pertains to killing viral and fungal microorganisms on paper currencies and/or cleaning dirty paper currency and ultimately reconditioning the currency for longer use.
- While prior art devices for cleaning paper currency exist and fulfill their respective objectives and/or requirements, such devices generally do not provide for a paper currency sterilization system that allows killing viral and fungal microorganisms on paper currencies. U.S. Pat. No. 6,946,106 to Masyada is a device that provides for sterilization but is extremely complex and expensive to build and operate, and requires much maintenance. Prior art devices are generally known to consist basically of familiar, expected, and obvious structural configurations not withstanding the myriad of designs encompassed by the crowded prior art, which has been developed for the fulfillment of countless objectives and requirements. While these devices fulfill their respective, particular objections and requirements, they do not describe paper currency reconditioning with the cleaning and sterilization process as described herein.
- In this respect, the paper currency system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of cleaning dirty and soiled paper currency as well as for the purpose of killing viral and fungal microorganisms on paper currencies, wherein the apparatus or system is simpler and less expensive to build and operate, and requires less maintenance.
- The present invention further as an objective addresses needs in the following areas:
- Health issues are decreased due to handling clean and sterilized currency;
- As for National and International Security, the sterilization process will be necessary in dealing with bio-terrorism, either as a preventative or recovery effort, should currency be used in terrorist attack;
- Life expectancy of currency substantially increases by cleaning and reconditioning; and
- Currency handling equipment will have substantially less downtime due to dirt jamming the equipment.
- Therefore, it can be appreciated that there exists a continuing need for clean, reconditioned, sterilized and improved paper currency condition, and the present invention substantially fulfills this need.
- In view of the foregoing disadvantages inherent in the prior art paper cleaning devices of known designs and configurations, the present invention provides a new and improved currency cleaning, sanitizing and reconditioning system over current art in one operation. This system will show none of the disadvantages of the prior art.
- To attain this, the present invention comprises a method of cleaning a paper currency through a washing portion or section of a paper currency cleaning system. The currency notes ride on a grooved belt with opposing individually grooved driver rollers in a staggered pattern to accomplish 100% exposure of the notes on the side being cleaned. The currency can be fed narrow end first or wide end first and in a single or dual or other multiple side by side orientation as desired and depending on the width of the system when fabricated. The grooved belt is to accommodate in the transition area of belts segments within the system, guide rods. These guide rods are typically round non-corrosive, stainless steel or equal guide rods that hold the currency on the belt between the driver rollers as it moves from roller to roller through the washing section. Between the staggered rollers, there are high pressure staggered nozzles that spray a cleaning solution, which may be optionally heated, suitable for cleaning paper currency from the wash section onto the top of the notes to wash away dirt, oils, and other contaminates on one side.
- After a designated length of belting, the notes pass through the second cleaning area or section that has the same specially developed inverted belt, roller, and staggered spray nozzle system, which duplicate the first area cleaning process. The purpose of the whole conveyor section being inverted is to accomplish 100% cleaning of the currency on the opposite side of the notes yet to be cleaned. As noted above, the cleaning solution can be heated if desired. This cleaning area is self-contained to repeatedly reuse the solution. This is accomplished by filtering the solution through a reservoir before passing it through the high pressure pump back to the cleaning nozzles.
- This self-contained washing system is to minimize servicing of the device and is controlled by an operating panel. This panel measures pump pressures to determine the filter and cleaning solution replacement cycle. The cleaning solution may optionally be thermally controlled as well from an operating panel.
- The plurality of guide rods are arranged in a staggered array and are oriented and located so as to hold the currency in place against the conveyor belt as the currency is passed through the invention cleaning system.
- The notes, after passing through the washing section, are transferred to a mesh belt to expose both sides of the notes. The stages of drying process from both sides are:
- a. Air wiper nozzles with pressured air remove excess moisture;
- b. Squeeze rollers further remove more moisture from the notes; and
- c. Heated air nozzles direct forced heated air on both sides of the notes.
- The notes then enter the sanitization area of the system and pass over mesh belting, where the notes are misted on both sides with a sanitizing solution through low pressure nozzles to give the notes 100% coverage. This sanitization area is also self-contained and filtered to help prolong the solution use and service cycle.
- Finally, the notes pass through another high pressure air wiper to remove moisture, and then through high pressure rollers to recondition the notes such as to remove wrinkles and folds. The notes are then deposited into a collection box (not shown).
- Feeding/loading and receiving/collecting stackers or boxes are known in the art and are commercially available from companies such as National Cash Register (NCR) and are therefore not depicted in the drawings which descriptions follow.

FIGS. 1-5 and 6A-6D disclose a system for cleaning paper currency, which is depicted generally as 10. - The
present invention 10 comprises awashing portion 12 having afirst washing section 12 a and asecond washing section 12 b, and dryingportion 14 downstream of thewashing portion 12. Thewashing portion 12 has afirst belt portion 16 a in thefirst washing section 12 a with a plurality of opposing rows of drivenrollers 18 a in a predetermined staggered pattern, and asecond belt portion 16 b in thesecond washing section 12 b with a second plurality of opposing rows of drivenrollers 18 b in a predetermined staggered pattern. Thesecond belt portion 16 b and its opposing drivenrollers 18 b are in an inverted orientation from thefirst belt portion 16 a and its opposing drivenrollers 18 a. The drivenrollers rollers drive using motor 32 and its driven pulley orgear 18 d. Pulley orchain 18 e is used to driverollers - The paper currency is fed and distributed on the
first belt portion 16 a for conveyance through the first andsecond washing sections first washing section 12 a and an opposite side of the paper currency in thesecond washing section 12 b. - The cleaning solution is sprayed on the currency from an array of a plurality of
nozzles 22 a using water as the solution of another appropriate cleaning solution. The solution may be optionally heated if desired. One such way of providing this feature is to have the solution which is stored in thetank 22 b heated using a temperature controller and electric or gas heating means similar to those found in water heaters. Another method is to provide an in-line instant heat electric or gas powered device. - The invention includes means for holding the paper currency in place on the first and
second belt portions second belt portions washing portion 12. Downstream of the cleaning orwashing portion 12 is a meshedbelt conveyance portion 24 on which the paper currency passes from thewashing portion 12 onto the meshedbelt conveyance portion 24. As the currency proceeds down the conveyor line, it is dried and reconditioned using various means as the currency passes on the meshedbelt conveyance portion 24. - The means for drying and for reconditioning the paper currency as it passes on the meshed
belt conveyance portion 24 can be done in a variety of ways such as by using anair pump 26 and/or heater/air pump combination 34 connected to a plurality ofair wiper nozzles 26 a directed from above and below the meshedbelt conveyance portion 24, with pressured air, for removing excess moisture from the cleaned paper currency, by using a plurality ofheated air nozzles 26 b having means for directing forced heated air on both sides of the paper currency, and/or by using one ormore pressure rollers 26 c configured to squeeze the paper currency against a surface of the meshedbelt conveyance portion 24 for removing moisture and wrinkles from the paper currency. - In one embodiment, the first and
second belt portions more grooves 16 c running longitudinally on each of the first andsecond belt portions second belt portions guide rods 20, wherein a designated portion of theguide rods 20 adjacent a transition area of the first andsecond belt portions more grooves 16 c in the first andsecond belt portions corresponding guide rods 20 adjacent the transition area to be located within the two ormore grooves 16 c for facilitating the conveyance of the currency from thefirst washing section 12 a to thesecond washing section 12 b and from thesecond washing section 12 b to the meshedbelt conveyance portion 24. As can be seen in the drawings, therods 20 are generally small diameter pins with ends welded or otherwise attached to cross-member plates. This allows therods 20 to be segmented and spaced-apart to ensure that some guide rods 20 (at least two) are always in contact with one surface of the currency.Rods 20 in the transition areas are placed so as to be co-linear with thegrooves 16 c of thebelts - In an alternative embodiment as shown in
FIGS. 7-11 and 12A-12B, a sanitizingportion 28 is added downstream of thewashing portion 12 and the dryingportion 14. The sanitizingportion 28 can be configured to have the meshedbelt conveyance portion 24 continue from the dryingportion 14 or it can be configured to have another transition area where the meshbelt conveyance portion 24 transitions into another meshed belt portion, not shown. InFIGS. 1 and 7 , it is understood thatmesh belt 24 may also be representative of adjoining sections of mesh belts. The sanitizingportion 28 includes means for misting a sanitizing solution on both sides of the paper currency as the paper currency travels on the meshedbelt conveyance portion 24. An array of spaced-apartspray nozzles 28 c are located so as to pump and spray a fine mist of a sanitizing solution on the cleaned currency. The mist is so fine that little or no residual mist needs to be collected; however, if residual condensate of the misted spray solution is collected, it can be drained to the sanitizing tank for recycled use through afiltering medium 28 d. - Although the final process is contemplated to be the sanitizing process if this process is added to the
system 10, the sanitizing process may also include means for drying and for reconditioning the paper currency as it passes on the meshedbelt conveyance portion 24. This feature can be provided using the same method as described above for the currency leaving the washing process. Accordingly, as depicted inFIG. 7 , a second hotair dryer pump 34 may be added after the misting of the sanitizer is completed if desired with associatednozzles 26 b as depicted inFIG. 6D . In addition,additional pressure rollers 26 c may also be added in line after the second hot air application process is completed. - As noted above, the
system 10 includes means for storing the cleaning solution using atank 22 b and apump 22 c to pump the cleaning solution through a plurality ofspray nozzles 22 a at a desired pressure. In a preferred embodiment, the cleaning solution should be recycled by having means for collecting sprayed cleaning solution. This can be done by having a drainage collection pan, where the solution is routed back to thecleaning solution tank 22 b. Preferably the collected solution should be filtered either before entry into thesolution tank 22 b or thefiltering medium 22 d can located in line between thetank 22 d and thenozzles 22 a. - Similarly, the sanitizing
portion 28 has means for storing the sanitizing solution, for example atank 28 a and pump 28 b for pumping the sanitizing solution through a plurality of mistingnozzles 28 c at a desired pressure.
