DETAILED DESCRIPTION

[0026] In this document, the singular forms a, an, and the include plural references unless the context clearly dictates otherwise. The term comprising means including, but not limited to. Similarly, the term comprises means includes, and is not limited to. Unless defined otherwise, all technical and scientific terms used in this document have the same meanings as commonly understood by one of ordinary skill in the art.

[0027] In this document, terms that are descriptive of position such as upper and lower, horizontal, vertical and the like are intended to indicate relative positions with respect to the components for which those terms are descriptive, and are not intended to be absolute and require that the component remain in that absolute position in all configurations. Except where specifically stated otherwise, numeric descriptors such as first, second, etc. are not intended to designate a particular order, sequence or position in an overall process or schema, but instead are simply intended to distinguish various items from each other by describing them as a first item, a second item, etc.

[0028] The terms media transport system and media transport device refer to a set of hardware components that are configured to receive printed media (i.e., a substrate onto which text and/or graphics have been printed) and move the printed media through one or more modules that perform various processing steps on the printed media, such as position adjustment, sensing, printing and/or delivery to a final destination. The media may include currency, admission tickets, or other documents. A currency transport device or currency transport system is a type of media transport device that is configured to process and convey printed financial instruments such as currency notes, checks, money orders, bank notes and the like. In this document the term currency is intended to include actual currency notes or bank notes, as well as other documents that are printed financial instruments such as checks and money orders.

[0029] In this document the terms substantially fixed and substantially stationary refer to objects that do not move through a travel pathway but remain within a single location in the travel pathway. An object may vibrate, flex or even wiggle or be jostled while remaining substantially fixed or substantially stationary so long as it is not moving through the media transport system to different positions within the travel pathway. The terms substantially fixed and substantially stationary therefore include, but are not limited to, completely fixed and stationary positions.

[0030] FIG. 1A is a block diagram that illustrates example components of a media transport system, such as may exist in a prior art automated teller machine or ticket taking machine. FIG. 1B illustrates an example of an automated teller machine that includes the components shown in FIG. 1A. The machine includes a housing 120 that contains the media transport system. As shown in FIG. 1B, optionally the housing may include a door 121 and one or more extendible rails 122, shuttles, or other movable mechanisms that may be used to remove at least part of the media transport system from the housing 120.

[0031] The media transport system includes components such as a receiver 111 that includes belts, rollers or other conveying mechanisms that will receive printed media into the system via an opening in the housing. For media transport systems that are currency transport systems, the received 111 may be referred to as a currency acceptor. The media transport system also may include a separator module 112 that includes belts, rollers or other media conveyor devices that separate stacked printed media, such as stacked checks or currency notes. In currency transport systems, such rollers are sometimes referred to as pick rollers or pick wheels. The media transport system also may include an alignment module 113 that includes belts, rollers or other conveying mechanisms that will adjust a position of the media with respect to an internal reference point. The media transport system also may include an imaging system 114 with a camera and/or other sensors and associated programming that can detect what the media is and/or what is printed on the media. The media transport system also may include a transport module 115 with one or more belts, rollers or other media conveyors that will move the printed media to an appropriate destination 116 such as a shuttle, bin or exit port. The media transport system also may include other modules, such as a printer that can apply additional printed markings to the printed media. The areas within each module through which the printed media passes form a media travel pathway from the receiver's intake to the final destination.

[0032] FIG. 2 illustrates an example of a cleaning system that includes a cleaning substrate 201, which sometimes may be referred to as a cleaning card, that may be used to clean various components of a media transport system such as that shown in FIGS. 1A and 1B. The cleaning substrate includes a cleaning face 202 (which as shown is an upper face) and an opposing face (not shown, since it is under cleaning face 202) that may or may not also be a cleaning face. At least one of the cleaning faces may be coated with a cleaning solution such as a solvent so that internal components of the media transport system may be cleaned when the components move along or across the cleaning face of the substrate. Example cleaning solutions include isopropyl alcohol, deionized water, alkaline surfactants, and other materials or combinations of these. Alternatively, a cleaning face may be textured or made of fiber that will promote friction when a movable object is moved against the cleaning face. The cleaning substrate may be made of a flexible, tear-resistant material such as a fibrous aramid or meta-aramid fabric material such as that marketed under the NOMEX brand; a cellulosic material; a flexible polymeric substrate provided with thin, non-woven layers made of absorbent material such as that marketed under the SONTARA brand; a sponge made of polyurethane or other type of foam; or a combination of any of these, such as a sponge coated with a fabric, non-woven absorbent or cellulosic material.

[0033] The cleaning substrate also includes one or more locking members 203 such as holes, slots and/or tabs that are configured to align with (such as by fitting over or locking into) a stationary component of the media transport such as a post. Each locking member 203 is a structure that will hold the cleaning substrate 201 in place in a substantially fixed position within the media travel pathway while moving parts of the media transport system pass over or along the cleaning substrate and are cleaned.

[0034] In the example shown in FIG. 2, the locking members 203 may be tabs that extend away from the cleaning face 202 in a direction that is perpendicular to the path of travel of the media transport device. In the embodiment shown, each of the tabs may include a receptacle that is positioned to align with a post of the media transport device. If the media transport device includes multiple posts, or if the substrate includes multiple locking members 203 such as in the example shown in FIG. 2, the receptacles of the locking members 203 of FIG. 2 may be placed over various posts so that the cleaning substrate can be used in multiple positions in the transport system. In an alternate example shown in FIG. 3, the cleaning substrate 301 may include a locking member 303 with multiple receptacles 304, 305, each of which is positioned to align with a post of the media transport device (which may be a single post, or multiple posts) so that the cleaning substrate may be aligned in multiple positions within the media travel pathway of the media transport system. Another example of locking members will be discussed below in the context of FIG. 9.

[0035] Alternatively or in addition to a locking member, the cleaning substrate may be held substantially fixed by friction within the media travel pathway when the pathway is closed. This may happen, for example, if the cleaning substrate is at least at thick or thicker than the closed media travel pathway so that the cleaning substrate contacts interior components of the media travel pathway and is held against those components by friction. A cleaning substrate made of a compressible foam core and fabric or other abrasive cover may be useful in such an embodiment.

[0036] The cleaning substrate has a length and width that is sized and shaped to fit within the media travel pathway of the transport device with which the cleaning substrate is intended to be used, and the locking tabs will be positioned to connect to the posts or other connecting structures of the transport device with which the cleaning substrate is intended to be used. As used in this document, the term fit within does not necessarily mean that the substrate is entirely held within the media travel pathway, as a locking tab or other relatively small portion of the substrate may extend from the media travel pathway into other areas of the interior of the transport device. However, in some optional embodiments the cleaning substrate will be retained completely within the media travel pathway. In some optional embodiments, no portion of the substrate will extend from a media acceptor port (such as a currency acceptor slot) of the transport device.

[0037] In addition, referring to FIG. 3, the cleaning substrate will include multiple scarifying holes 312, 313 that are positioned to align over, under, or in between rollers of the media transport device. A scarifying hole is an opening created and positioned to provide a scraping edge against which another item may be scraped so that debris or other contaminants on the item's surface are scraped and thus removed via movement of the hole, the item or both. Referring to FIG. 4, the substrate 401 includes a scarifying hole 411 sized and positioned to fit between an idle roller 423 and drive roller 425 of the media transport system. In normal operation when the media transport system receives printed media, the drive roller 425 presses against the media, and a motor turns the drive roller 425 to move the media through the media travel pathway. The idle roller 423 is positioned proximate to the drive roller 425 to serve as a backstop for the force of the drive roller 425. The printed media passes between the idle roller 423 and drive roller 425. In a cleaning operation, the drive roller 425 is activated but the cleaning substrate remains stationary, anchored in the transport path by the locking structure(s). The scarifying hole 411 receives the idle roller 423 and/or the drive roller 425 so that one or both rollers scrape along the edges of the scarifying hole 411 and are thus cleaned. In configurations that only use a drive roller without an idle roller, the drive roller may be received into the scarifying hole.

[0038] The drive rollers and/or idle rollers of other drive roller 435/idle roller 433 pairs that are not aligned with the scarifying hole 411 will be wiped by the cleaning substrate. Then, when the cleaning substrate is moved to a different stationary position in the media transport path (and a different locking member receptacle or media transport system post is used to lock the cleaning substrate in the different position) the other drive roller 435/idle roller 433 pair may be aligned with the scarifying hole 411 or a different scarifying hole in the substrate.

[0039] Scarifying holes also may be sized and positioned to align with and accept one or more belts or other moving parts of the media travel pathway. For example, referring to FIG. 5, one or more axles 522, when activated, turn a belt 525 while the cleaning substrate remains stationary in the media travel pathway. If the scarifying hole has a width that smaller than, or at least no greater than, the width of the belt 525, the belt 525 will be scraped by the scarifying hole 511 and wiped by the cleaning substrate 501. In addition, if the scarifying hole 511 is positioned to align with the axle 522, the axle 522 may help push a segment of the belt 525 into the scarifying hole 511 to promote scraping of the belt 525 along the edge of the scarifying hole 511.

[0040] FIG. 6 illustrates an alternative to FIG. 5 in which, as an alternative to (or in addition to) a scarifying hole, a belt scraper is formed by one or more inwardly-facing flaps 618a, 618b that may be lifted upward or pressed downward so that the belt may be placed under or over each flap. Each flap 618a, 618b will have at least one side that is attached to the cleaning substrate and at least one edge that is formed by an angled or curved cut into the substrate so that the flap can be lifted or pressed and receive the belt. The edge may be a single curved edge as shown, or multiple angled edges may be used. As the belt is operated, the cut-away edge of the flap will scrape the belt. The face of the cleaning substrate also may wipe the belt. In addition, both sides of the belt may brush across the cleaning surface of the substrate and the flap as the belt passes over the substrate and under the flap (or over the flap and under the substrate). This may result in the deposit of dirt, oil or other contaminants 634 on the cleaning substrate, as shown in FIG. 6. Optionally, the flaps 618a, 618b may be adjacent to a scarifying hole 611. In some embodiments, the flaps 618a, 618b may serve as locking members to hold the cleaning substrate in a substantially fixed position by contact with the belts during operation. The embodiment of FIG. 6 also illustrates an embodiment with additional locking members 603 that are each an inwardly-facing slot into which a post of the media transport system may be placed.

[0041] Referring to FIG. 7, in some embodiments scarifying holes or other openings 711 of the cleaning substrate 701 also may be sized and positioned to align with one or more media sensors 722 within the media travel pathway. Such a sensor 722 may include a pressure sensor, an optical sensor, a temperature sensor, and/or any other sensor that is available in the media transport system and configured to detect placement of media (such as a cleaning card or currency) into the device and may, in some embodiments, include a transmitter 723a and receiver 723b as is shown in FIG. 7. The media transport device may use the sensor 722 to detect the position of the cleaning substrate 701 within the media travel pathway (e.g., based on pressure or optical data determine whether the sensor is over a scarifying hole). In addition, in some media transport systems one or more sensors 722 may be used to detect whether the device is jammed and media is not moving through the media travel pathway. If so, the placement of an opening 711 such a sensor can help avoid the media transport system stopping. The opening may be a hole in the cleaning substrate, or a transparent section of the cleaning substrate made of a clear material such as clear plastic, or a polyester film such as that sold under the MYLAR brand. The sensor can detect whether or not the cleaning substrate is in a proper cleaning position, rather than mis-aligned or jammed, because if the opening 711 not been positioned under the sensor 722, the sensor 722 would have detected the presence of the non-moving substrate and thus detected that the cleaning substrate is not moving through the device.

[0042] Referring back to FIG. 2, in some embodiments one or more of the scarifying holes 211 may include a scraper 217 that is attached to one or more edges of the scarifying hole. The scraper 217 extends inwardly toward the center of the scarifying hole 211. Referring to FIG. 4, depending on whether the alignment of the scraper 417 is positioned closer to an upper face, closer to a lower face, or centrally within the scarifying hole, the scraper may provide additional scraping force against the idle roller 423 and/or the drive roller 425.

[0043] Referring back to FIG. 3, in some embodiments the cleaning substrate 301 may include any number of forward-facing or reverse-facing flaps 327, shown here as forward-facing flaps formed by cuts made into the cleaning substrate 301, that are positioned along a forward-facing edge (i.e., facing the direction of media travel in the media travel pathway) of the cleaning substrate. The flap 327 can be sized and positioned to fit within a slot of the media transport device to help retard forward or reverse movement of the cleaning substrate 301 in the media travel pathway and further anchor the cleaning substrate 301 in a stationary position during the cleaning operation. FIG. 6 illustrates another embodiment in which the forward-facing flap 627 is not on a leading edge of the substrate but instead is on a forward-facing edge of within an opening 628 within the cleaning substrate. The flap 627 also may, in some embodiments, serve as or be part of a locking member.

[0044] In various embodiments, a cleaning system may include multiple cleaning substrates that are sized, shaped, and which contain scarifying holes and locking structure to align within different modules of the media transport system. For example, a first cleaning substrate 201 such as that shown in FIG. 2 may be placed within the alignment module of a media transport device while the device is idle, and a second cleaning substrate 301 such as that shown in FIG. 3 may be placed within the receiving module of the media transport device while the device is idle. The media transport device may then be operated, and each of the modules will be cleaned at the same time.

[0045] FIG. 9 illustrates an additional embodiment of a cleaning substrate 901 that includes a set of locking members 923a . . . 923n that are tabs that extend downward (or upward) in a direction that is between about 45 and about 90 from the cleaning substrate, configured in row to be received by a set of rollers (such as picker rollers) in the media transport device. These tabs may have a thickness that, when uncompressed, is substantially equal to or larger than the thickness of a space between the rollers and their next adjacent component. Thus, in this embodiments the locking members 923a . . . 923n both hold the cleaning substrate in place and also serve to clean the rollers when the rollers are turned. In this embodiment and in other embodiments discussed above and below, the turning of the roller may be done manually, or by operation of a motor of the media transport device.

[0046] Optionally, cleaning substrate 901 may include a second face 905 with additional locking members 903a, 903b that extend away from the sides the cleaning substrate in a direction that is perpendicular to the direction of media travel in the media travel pathway. These side-extended locking members 903a, 903b may include openings that will fit over posts or other extended elements that are not in the media pathway. Alternatively, the side-extended locking members 903a, 903b may include no receptacle but have a thickness (when not compressed) that is thicker than that of the media travel pathway when closed so that the locking members will be held by the media transport device by friction when the device is closed. The second face 905 of the substrate may serve as a handle to hold and place the substrate into the media travel pathway.

[0047] As shown in FIG. 9, when manufactured the cleaning substrate 901 may be substantially flat, and locking members be formed as locking tabs 923a . . . 923n cut into a first cleaning face 904 of the substrate 901.

[0048] FIGS. 10A through 10C shows a method of using the cleaning substrate of FIG. 9. FIG. 10A shows that when placed into the media travel pathway of the media transport device 950, the cleaning substrate may be folded so that the locking tabs 923a . . . 923n extend downward (or alternatively upward) from the first and second faces 904, 905 in a row. As shown in the close-up of FIG. 10B the locking tabs 923a . . . 923n will be received by corresponding rollers 951a . . . 951n of the media travel pathway. After the locking tabs 923a . . . 923n are placed against their corresponding rollers 951a . . . 951n, the cleaning faces 904, 905 may be folded down onto the media travel pathway. Locking members 903a, 903b may be placed over posts or other receivers of the pathway. Optionally, the cleaning substrate 901 may include one or more fold lines 920, formed by score lines or crease lines in the substrate, to assist in and help enable folding and positioning the substrate in place in the media travel pathway.

[0049] FIG. 9 also shows that the cleaning substrate 901 optionally may include scarifying holes 911a . . . 911n that are configured to be placed between pairs of drive and idle rollers inside of the media transport device. The scarifying holes 911a . . . 911n may be positioned forward of the locking tabs 923a . . . 923n in the media pathway (i.e., toward a front end of the card that faces the path of travel in the media travel pathway), or in the opposite direction (i.e., toward a rear end of the card that faces away from the path of travel). The scarifying holes 911a . . . 911n may be positioned in a first row across the face of the cleaning substrate 901 while the locking tabs 923a . . . 923n may be positioned in a second row across the face of the cleaning substrate 901. Although not shown in FIG. 9 or 10A-10C, the cleaning substrate 901 also may include one or more openings (holes or clear material) that are positioned to fit over a media sensor of the media transport device. Any cleaning face of the cleaning substrate 901 also may include or be coated or treated with a cleaning solution.

[0050] In some embodiments, in any of the embodiments described above the cleaning face(s) of the cleaning substrate may be textured to provide additional cleaning function (e.g., by applying friction to belts that pass over the cleaning substrate). The cleaning face(s) also may include a material such as a meshed loop structure that entangles dirt to trap it.

[0051] FIG. 8 illustrates a method of using a cleaning system such as that described above. The method includes opening the media transport device to form a portal into which a first cleaning substrate may be placed (step 801). The portal will be a portal that is not accessible during normal operation of the device. For example, the portal will not be a currency acceptor slot that is used during normal operation to insert currency into the media transport device. Instead, the portal will be formed by opening one or more of the modules that form the media travel pathway. The cleaning substrate will be inserted into a media travel pathway of the media transport device through the portal, and the cleaning substrate will be placed into a fixed position without operating the motor that actuates the media conveyors (i.e., belts and/or rollers) of the media transport device (step 802).

[0052] In some embodiments, the media transport device may detect that a cleaning substrate has been placed into the media travel pathway, and if so it may automatically change its mode of operation to a cleaning mode rather than a normal operating mode. The cleaning mode may differ from the normal mode in that, for example, it may hold the cleaning substrate in a particular location for a defined period of time before moving the substrate to a next section, or it may adjust the pressure applied to the substrate, or it may override a device jam alert and permit the media conveyors to turn even though the cleaning substrate is not moving through the machine in a normal mode of operation. Detection that the substrate is a cleaning substrate may occur by any suitable means, such as by manual input, by detecting a shape of the substrate, or by using image processing to detect a code or other identifying indicia that is printed on the substrate.

[0053] If the cleaning substrate includes scarifying holes, the scarifying holes may be aligned to rollers, belts, sensors and/or other selected components of the media transport device that are in the media travel pathway. If the cleaning substrate includes one more flaps for cleaning a belt, one or more belts may be positioned over or under the flap(s). If the cleaning substrate includes one or more locking members, the locking member(s) may be aligned with post(s), roller(s) or other components that will hold the locking members while the cleaning substrate is within the media travel pathway. If the cleaning substrate includes a latching flap, the latching flap may be placed within a slot in the media travel pathway.

[0054] A first section of the media transport device will thus receive the cleaning substrate through the portal. The cleaning substrate may remain fully within the media travel pathway. Alternatively, a portion of the cleaning substrate may extend out from the media travel pathway, such as through a currency acceptor slot, so long as enough of the cleaning substrate remains within the pathway to provide a cleaning function.

[0055] Optionally, one or more additional cleaning substrates may be placed into additional sections of the media travel pathway of the media transport device (step 803) as described above.

[0056] The portal to the first section will then be closed (step 804) so that at least some of the belts or rollers contact the first cleaning substrate. The media transport device will then be operated so that a motor of the device causes the belts or rollers to move, contact the first cleaning substrate and be cleaned while the first cleaning substrate remains substantially fixed within the first section of the media transport device (step 805). In some situations, operation of the media transport device may be manual operation of the belts or rollers (e.g., manually turning them). After operation, the device may then be turned off (e.g., powered down or moved to an idle mode in which the belts and rollers of the media travel pathway are not operated), and portal(s) will be opened to remove the cleaning substrate(s) from the media travel pathway (step 807).

[0057] Optionally, before opening the first section and placing the cleaning substrate through the portal, the method may include operating the media transport device and, while operating the motor, placing a second cleaning substrate (step 810) that includes a cleaning solution into a second portal that is accessible during operation of the motor so that the second cleaning card is received into, and moves through the media transport device, and the cleaning solution contacts the belts or rollers while the second cleaning substrate moves through the media transport device. In this way, cleaning solution may be applied to the media travel pathway before the stationary card is inserted, and the stationary card may then require little or no cleaning solution. This also may help pre-clean the components of the media travel pathway before the stationary cleaning substrates are inserted.

[0058] Optionally, after operating the media transport device so that the belts or rollers turn, contact the first cleaning substrate and are cleaned (step 805), the method may include opening the portal to expose access to a section of media travel pathway and repositioning the cleaning substrate to a second position in the section according to a second alignment positions (step 806). That portal may then be closed, and the media transport device will be again operated so that at least some of the belts or rollers turn, contact the cleaning substrate and are further cleaned while the cleaning substrate remains substantially fixed in the second position.

[0059] The methods and systems described above may result in significant time savings as compared to manual cleaning. In addition, they can help ensure that cleaning occurs in small and/or hard-to-reach segments within the media transport device.

[0060] The features and functions described above, as well as alternatives, may be combined into many other different systems or applications. Various alternatives, modifications, variations or improvements may be made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
