Description

Value-document processing device and a method for reducing dust in the value-document processing device

The present invention relates to value-document processing apparatus and a method for reducing dust in a housing of the value-document processing apparatus.

Under value documents are understood leaf-shaped objects that represent, for example, a monetary value or an authorization and therefore should not be arbitrarily produced by unauthorized persons. They therefore have features which are not easy to manufacture, in particular to be copied, whose presence is an indication of the authenticity, i. the production by an authorized agency. Important examples of such value documents are coupons, vouchers, checks and in particular banknotes.

Due to the large number of documents of value in circulation and the need to check them, there are value-document processing devices which serve to check the value documents mechanically, for example, on their authenticity, fitness for circulation or denomination. For this purpose, value-document processing devices frequently have testing devices for checking value documents in accordance with predefined criteria, which in particular can have optical sensors. The test equipment and in particular optical sensors of such test equipment are generally sensitive to soiling, especially dust, which may settle on parts of the test equipment, for example a window of an optical sensor through which optical radiation passes to or from the document of value. From a certain degree of contamination, the testing device must be cleaned, which requires effort and restricts the possible operating time of the value-document processing device. The invention is therefore based on the object of providing a valuable document processing device with a checking device for checking value documents, in which contamination by dust can be reduced, and to provide a corresponding method for reducing dust in such a value-document processing device.

The object is achieved by a method for the reduction of dust in a housing of a value-document processing device that provides input for value documents to be processed, an output and / or a

Storage device for processed value documents, a transport device for occasional transport of documents of value from the input along a transport path to the output or the storage device, and arranged in the housing testing device for testing on her occasionally transported past value documents, wherein the method dust at least two different points of the transport path and / or is sucked by a hand cleaning section with a relative to the testing device in the region of the test device movable suction port.

The object is further achieved by a value-document processing device with an input for value documents to be processed, an output and / or a memory device for processed value documents, a transport device for the occasional transport of value documents from the input along a transport path to the output or the Storage device, a housing, a housing arranged in the test device for testing on her occasionally transported past value documents, and with a Saugleitungssystem for suction, the connection for a suction unit for the extraction of air with dust from the Suction line system and at least one connected to the terminal hand cleaning section with a in the region of the test device relative to this movable suction port and / or at least two connected to the terminal line sections arranged at different sections of the transport path, directed onto the transport path suction openings, through the dust from along the Transport path transported value documents is transportable, has.

The value-document processing device is used for the mechanical processing of value documents. In this context, processing may in particular be understood to mean the counting of value documents and / or the checking of value documents in accordance with predefined criteria and / or the sorting of value documents, for example as a function of the result of an examination or other criteria. The checking of the value documents may in particular be the determination of the type of value documents, in the case of bank notes, for example, their denomination, and / or the examination for authenticity or the existence of a forgery on the basis of predetermined criteria for the authenticity or the existence of a forgery, and / or the examination of the status of the documents of value, in particular their fitness for circulation and / or their suitability for use in cash dispensers. For processing, the value documents can be entered individually or preferably as a stack into the input or input device for value documents to be processed, depending on the design of the value-document processing device. The output or output device and / or the storage device for processed value documents, which may, for example, comprise at least one compartment or a value-document storage, for example a cassette or a reel storage, serves to output or record processed value documents. For processing, the value documents with the transport device can be input from the input. preferably singulated along the transport path, the course of which is given by the transport device, are transported to the output or the storage device. The test device used for the test is arranged on the transport path, so that it can be used occasionally for checking on their conveyed value documents.

To protect against contamination and mechanical effects from outside, and for the mechanical and acoustic protection of operating personnel, the value-document processing device has the housing, which can be constructed in one or more parts and the modules, in particular the input, the output, the transport device and the testing device of Wertdokumentbearbeitungsvorrichrung at least partially encloses. Preferably, the housing encloses said assemblies largely to input and output openings for the processed or processed value documents largely, more preferably completely.

The testing device can be designed to carry out the abovementioned investigations or tests, and for this purpose comprise at least one sensor by means of which physical, in particular also optical, characteristic shanks of the value document can be detected and tested. Often, the tester will also include multiple sensors.

To reduce dust in the interior of the housing and thus in particular also in the area of the test device, more precisely a sensor of the test device, two measures are provided which can be taken independently of one another or preferably in combination.

On the one hand, dust can be removed from the transport path or the transported value document along at least two points of the transport path. be sucked. In order to prevent this, the dust concentration in the housing can be lowered by extracting dust in the area of its formation during transportation of the documents of value, in particular of contaminated documents of value, before it can reach the area of the test device, in particular a sensor of the test device ,

On the other hand, a hand-cleaning section with a relative to the test device in the region of the test device movable suction opening may be provided, is sucked through the dust. Thus, a maintenance person can easily clean a dirty sensor of the test device by moving the suction opening so that the dust sucked at a suitable location and thus from the housing interior at least in the area of the test device, preferably from the entire housing interior, optionally up to a receptacle for the extracted dust is removed. The suction provides over other alternatives such as the blowing away or wiping dust the advantage that the dust is removed from the test device also, for example, for wiping hard to reach places and from the interior of the housing. This has the advantage that the effect of the cleaning lasts longer than with a blowing away of dust.

For this purpose, the value-document processing device has the suction line system, which initially has the connection to which a suction unit, that is to say a device for generating a negative pressure, can be connected. As a suction unit, in particular, a pump may be used, which may have a receptacle or a dust collecting device, such as a dust bag, for receiving dust from the extracted air. The suction unit does not necessarily need to be part of the value-document processing device. The connection may in particular be arranged in a wall of the housing or within the housing.

The suction line system further has at least one suction line connected as tightly as possible to the connection, through which air and in particular dust can be sucked out through the connection. In this case, at least two types of suction lines or Saugleitungsabschnitten are possible, which may be present alternatively or cumulatively.

On the one hand, the hand-cleaning section may be provided, the suction opening of which is movable in the region of the testing device.

On the other hand, the at least two line sections may be provided with suction openings. The line sections may form branches of a portion connected to the terminal or be part of the same line. The two line sections can be arranged in particular relative to the test device or the housing stationary. The suction openings can be arbitrarily aligned, but preferably they are directed to the transport path, particularly preferably so that air is sucked orthogonal to the surface transported value documents or tangentially transported to surface value documents.

This value-document processing device is particularly suitable for carrying out the above-mentioned method.

The hand cleaning section is preferably at least while it is not used for suction, more preferably completely, disposed within the housing. This allows a more advantageous design of the housing and prevents mechanical damage. The hand cleaning section basically be constructed arbitrarily. For example, it may have two rigid parts connected by a joint, one of which has the suction opening. Preferably, however, in the method as a hand-cleaning section, a section is used which has a flexible conduit part, preferably a hose, at the free end of which preferably a suction brush with the suction opening is arranged. In the value-document processing device, the hand-cleaning section may have a flexible conduit part, preferably a hose, at the free end of which preferably a suction brush with the suction opening is arranged. The use of a hose has the advantage that the hand cleaning section is very easy and inexpensive to produce and also allows extensive freedom in the movement of the suction opening.

The at least two line sections are preferably also disposed within the housing. Their arrangement is in principle arbitrary, however, the following embodiments, which can be applied alternatively or cumulatively, have proven to be particularly effective.

Thus, in the method preferably dust can be sucked off at least one of the at least two points so that dust is sucked from two different sides of a value document. In the valuable document processing apparatus, the suction openings of the at least two line sections or two suction openings of one of the at least two line sections, ie the at least one suction opening of the line section and a further suction opening of the guide section, can be arranged so that dust is sucked from two different sides of a document of value , This has the advantage that the dust entry through the value document is kept particularly low. In particular, therefore, dust at one of the at least two locations may for example be extracted from a first side of a value document and at another of the at least two locations from the first opposite side of the value document.

Basically, dust or air with dust needs to be sucked off only at the small point on the transport path. Preferably, however, in the method, dust is sucked off at at least one of the at least two locations over the entire width of the value documents. This allows a particularly extensive extraction of dust, especially at the edges of a value document. In the Wer tdokumentbearbeitungs device can have at least one at least two line sections a total of several suction openings, which are arranged transversely to the transport direction of the documents of value, preferably over the entire width. Alternatively, the suction opening can also be slit-shaped and extend with its longer side transversely to the transport direction, preferably over the entire width of the transport path or the value document.

In this case, they are preferably arranged at the points of the transport path at which dust can be detached or rubbed off from them by mechanical stressing of the value documents.

The possibilities mentioned below can be used alternatively or cumulatively.

Thus, in the method, the input can have a singulation device for singling value documents of a stack of value documents to be processed and transfer to the transport device, and at least one of the positions on the singling and / or on a transitional lie between the Vereinzier and the transport device. In the case of the value-document processing device, for this purpose, the input can have a separating device for separating value documents of a stack of value documents to be processed and transfer to the transport device, and the at least one suction opening of at least one of the sections can be arranged at the singler and / or at a transition point between the singler and the transport device may be arranged, preferably in order to eliminate dust resulting from the singulation. The transition point is preferably within the housing. This alternative offers the advantage that dust can be extracted very early during transport. In particular, only slightly adhering to the surface of documents of value dust can be removed so early.

Further, in the method, the transport path may have a bend and at least one of the locations may be at the bend. For this purpose, in the value document processing device, the transport path can have a bent section and the at least one suction opening of one of the sections can be arranged on the bent section.

Also, in the method, a value document can be deflected during transport at a deflection point, wherein at least one of the points is located at the deflection point. The transport device, in particular for forming the bend, can for this purpose have at least one deflection roller on which the direction of the transport path is changed, and the at least one suction opening of the at least one line section can be arranged on the deflection roller.

Moreover, in the method, at least one of the locations can lie on a section of the transport path, via the document of value belting. go, preferably on pairs of roles to be transported. In the case of the value document processing device, the at least one suction opening of one of the at least two line sections can be arranged on a section of the transport device which is designed for the conveyorless transport of documents of value and for this purpose preferably has at least one driven pair of rollers, particularly preferably at least two driven pairs of rollers. Because dust can cause excessive dust in such sections, extraction is particularly effective here.

Furthermore, in the method, the transport path may have two successive bends or deflection points, and at least one of the locations may lie between the bends or the deflection points. In the case of the value-document processing device, the transport path may have two successive bent sections or the transport device may have two deflection rollers and the at least one suction opening of one of the sections may be arranged between the bent sections or between the deflection rollers.

The transport device can also have a section, which transports the valuable documents by means of at least one transport belt, and a belt-free section, which transports the documents of value without transport belts. In the method, at least one of the locations may be at the transition point between the sections. In the case of the value document processing device, the transport device preferably has a transport section, which transports the documents of value by means of at least one transport belt, and a belt-free transport section, which transports the documents of value without transport belts, and the at least one suction opening of at least one of the suction line system sections is at the transition point between the transport arranged sections. This option offers the advantage that during the transition between the transport section, dust which may have formed due to slippage between the document of value and the transport device can already be locally extracted before it can reach the area of the test device.

Furthermore, the test device can identify an optical sensor with a sensor window arranged on the transport path. The method may then be one of the locations on or opposite to the sensor window. In the value-document processing device, the at least one suction opening of one of the at least two sections can be arranged on or opposite the sensor window for this purpose.

In principle, the line sections, in particular in the region of the suction opening, can be configured as desired. However, it is preferred that at least one of the sections has a guide device for documents of value or for guiding documents of value in which the at least one suction opening is formed. It can thereby be achieved that, even in the event that parts of, for example, limp value documents are pulled in the direction of the suction opening, the probability of a transport disturbance is substantially reduced, thanks to the guidance on the guide device. The guide means need only be designed so that in the case of too strong deflection of sections of a document of value acts leader, but not in normal transport.

In particular, the guide means may extend in the transport direction ribs, between which the at least one suction opening is arranged. This embodiment has the advantage that a gene of a document of value at the suction opening and thus a strong deceleration can be avoided with high security.

The suction line system can be configured as desired. For example, the suction line system can only have sections that are firmly connected to one another. However, it is also possible that in the value-document processing device, the housing has a housing opening through which access is at least possible to the test device, and a cover member for covering the housing opening, between an open position in which access to the tester is possible , and a cover position in which the housing opening is at least partially, preferably completely covered, movable, and that the Saugleitungssystem has at least one firmly connected to the terminal channel portion and at least one connected to the cover channel portion, which are designed so that they together form a channel section through which dust can be sucked off when the cover element is in the covering position. In particular, the channel portions may be formed so that suction of dust through the fixedly connected to the terminal channel portion and connected to the cover member channel portion is possible when the cover is in the covering position. This embodiment advantageously offers a high degree of flexibility in the arrangement and design of the suction line system.

Furthermore, a line section may comprise a pivoting section in which the suction opening is formed and which is accessible between a working position in which dust can be sucked off the transport path and a maintenance position in which an element of the device which is inaccessible by the pivoting section in the working position is accessible. The suction line system further essentially only needs to have one line which has the different sections and one end of which is connected to the connection or opens into it. However, it is also possible that the suction line system has branches comprising the various sections.

In particular, in the method of extracting dust from the at least two locations and extracting dust with the hand cleaning section, the same suction unit can be used to generate a negative pressure. For this purpose, the Saugleitungssystem in Wertdokumentbe- processing device in particular a connected to the terminal branching element having at least two branches, of which at least two branches one connected to the hand cleaning section and one with the at least two line sections, so that dust through the hand cleaning section or at least two line sections and the connection can be sucked off. This embodiment has the advantage that only one suction unit needs to be provided. In addition, the maintenance of the suction unit is simplified because aspirated collected dust needs to be removed only from a suction unit or a connected to this dust receiving device.

Although preferably the same suction unit is used for the suction of the dust with the hand cleaning section and the line sections, in the method preferably dust is used by the

Hand cleaning section not sucked off, while dust is sucked out at the points of the transport path. In the value-document processing device, for this purpose, the suction-line system may preferably have a distributor which, at least between a hand-cleaning position, in the dust can be sucked through the hand cleaning section, and a factory cleaning position in which dust can be sucked through the at least two line sections, and is producible. This has the advantage that a suction unit smaller power can be used, especially since in normal operation, a suction of dust through the hand cleaning section, although possible, but not absolutely necessary in some embodiments. As a distribution device, for example, at least two valves connected in series or a two- or multi-way valve can be used.

For the conversion of the distribution device, various variants are conceivable, some of which are described below and which can be used alternatively or in combination.

In principle, the distribution device can be turned back and forth manually by a user between the two positions. Furthermore, the value-document processing device may contain at least one controllable by inputs of a user control device, which outputs to appropriate inputs of the user actuating signals to the distributor, which has at least one controllable by the control signals drive, by means of which the distribution device between the two positions and is producible ,

However, the changeover can also take place automatically as a function of the state of the value-document processing device or parts thereof or of the state. Thus, in the method, the housing has a housing opening through which access is possible at least to the test device, and a cover member for covering the housing opening, which between an open position in which the access to the Test device is possible, and a cover position in which the housing opening is at least partially, preferably completely covered, is movable, and the suction of dust at the at least two different points of the transport path and / or by the hand cleaning section depending on the Position and / or movement of the cover between the opening and the cover done. For this purpose, in the value-document processing device, preferably the housing has a housing opening, by means of which access is possible to at least the test device, and a cover element for covering the housing opening, which is disposed between an open position, in which

Access to the test device is possible, and a cover position in which the housing opening is at least partially, preferably completely covered, is movable, and the position of the distributor can in dependence on the position of the cover and / or movement of the cover between the opening - Be set and the cover position.

The conversion of the distribution device can also be made depending on the state of the test device. Thus, in the method, the testing device can have an optical sensor, preferably an optical sensor with a window facing the transport path, and can be moved from an operating state in which testing of documents of value can be carried out by the test device into a cleaning state in which the optical sensor, in particular the window of the optical sensor, is accessible, and can be set back; then the suction of dust at the at least two different locations of the transport path and / or by the hand cleaning section in dependence on the state of the test device and / or a change in the state of the test device can be done. In the value document processing tification device may then preferably the test device, an optical sensor, preferably an optical sensor having a transport path facing window, and from an operating state in which an examination of value documents by the tester is feasible, in a cleaning state in which the optical sensor, in particular the window of the optical sensor, is accessible, and be zurückverbarbar further, the position of the distributor depending on the state of the tester and / or a change in the state of the tester, preferably automatically, be set.

If a suction on the transport path is not provided, then in the method the extraction of dust by the hand cleaning section in dependence on the state of the test device and / or a change in the state of the test device from the position of the cover and / or a movement of the cover between The opening and the covering position take place, ie only with a predetermined state or a predetermined position or a corresponding change air with dust is sucked through the hand cleaning section. For the device this means that the distribution device is replaced by a valve which is arranged in the connection between the terminal and the manual cleaning section and its position in dependence on the state of the test device and / or a change in the state of the test device from the position the cover element and / or a movement of the cover between the open and the cover position is set, or that the terminal and the distributor are replaced by a suction unit, its operating state depending on the state of the tester and / or a change in the state of the tester from the position of the cover ment and / or a movement of the cover between the opening and the cover position is set.

A dust extraction by the hand cleaning section is therefore only turned on when the test device assumes a suitable state for this purpose. This offers the advantage that the user does not need to input his own control signals, which could require a back and forth on the device and thus time especially for larger value document processing devices.

In particular, the setting of the distribution device can be carried out so that either a suction through the hand cleaning section or a suction takes place at the at least two points or by the at least two line section.

For the automatic conversion or setting several possibilities are conceivable.

For example, sensors may be provided which detect the state of the test device and / or a change thereof and / or the position of the cover member and / or a change of the same and emit corresponding sensor signals, to which the distributor or the valve or suction unit accordingly adjusted or adjusted.

Thus, in a preferred embodiment of the valuable document processing device, a drive controllable by a control device is provided for moving the cover element, and the control device controls both the drive and the distribution device. As already mentioned, in this case the distributor also has a corresponding chenden by the control device controllable drive for the conversion of the distribution device. Accordingly, in the case of a changeover depending on the state of the checking device in the value document processing device, a drive controllable by a control device can be provided for changing the state of the checking device, and the control device controls both the drive and the distributing device.

These embodiments have the advantage that the respective drives can be designed independently of each other, and thus optimized for their respective function.

Alternatively, however, it may also be preferred that in the value document processing device a common drive source is provided for moving the cover element or for changing the state of the test device and for changing the position of the distributor device. This drive source, which is mechanically coupled to the elements or devices mentioned, can then be controlled by the already mentioned control device which can be controlled by a user and / or by a control device which is controlled as a function of the state of the transport device, in particular the presence of a jam to be controlled.

In principle, the suction line system may still have, as line sections, branches which lead to other functional units of the valuable document processing device, for example to a separator. Preferably, however, the suction line system has only line sections which have suction openings for suction of dust, but do not serve to supply other components of the value-document processing device. In particular, the value-document processing device can process the suction Have gregat, which is then particularly preferably connected only to the terminal and therefore sucks only air through the suction line.

A device 10 for the processing of value documents 12, in the example banknotes, in FIG. 1 has in a housing 14 an input or input unit 16 which integrates an input compartment 18 for receiving a stack of value documents 12 to be processed and a separator 20 for separating the value documents 12 of the stack and delivery as individual value documents, an output or output unit 22 with at least two, in the example five, storage compartments 24 processed for filing value documents 12 and a transport device 26 for transporting isolated value documents 12 along a transport path 28 from the input unit 16 to the output unit 22. The transport device 26 has switches 30, by means of which branches of the transport path 28 are formed to the Ablagefä- ers 24. At the end of the branches Spiralfachstapler not shown in the figures are arranged, which store the documents of value in the storage compartments 24. On the transport path 28, a first test device 32 and a second test device 34 are arranged, the, in particular physical properties, such as their printed image and / or luminescence properties, detected at them occasionally transported past documents 12 and depending on the detected properties on the basis of predetermined criteria for the type, in particular the denomination, and / or the authenticity and / or the state of the value documents generated signals that reproduce or represent the type or the authenticity or the state of the respectively examined value document. A control device 36 is connected via signal connections, inter alia, to the test devices 32 and 34 and the transport device 26 and controls, inter alia, depending on the signals of the test devices 32 and 34, the transport device 26, in particular the switches 30, so that the value documents be stored according to the results of the examination and any other criteria in corresponding slots 24. The control device 36, not shown in the figures, has a user interface for inputting and outputting data relating to the operation of the device. The user interface may comprise, for example, a display device and a keyboard and / or a pointing device, for example a mouse, or a touch-sensitive display (touchscreen).

The housing 14 has a housing opening 38 through which access to the input 16, the test facilities 32 and 34 and corresponding parts of the transport path 28 are possible. The housing 14 further has a covering element 40 which is shown transparent in FIGS. 1 and 2 for covering the housing opening 38, which is possible between an opening position in which access to the testing devices 32 and 34 through the housing opening 38 is possible. and a covering position, in which the housing opening 38 is at least partially, preferably completely covered, movable. In this example, the cover member 40 is hinged at its upper edge, upwardly pivotable hood having an opening 42 in the Area of the input 16 for inserting a stack of value documents.

The housing 14 has at least one further opening 42 for the output 22, can be removed through the value documents from the output 22. The housing 14 may have other doors or flaps that allow access, for example, to parts of the transport path 28 that are not accessible through the housing opening 38.

The value-document processing apparatus 10 further has (see Figures 2, 3 and 4) a suction duct 44 for suction, which includes a terminal 46 for a suction unit 48 for the extraction of air with dust from the suction line 44 and at least one connected to the terminal hand cleaning section 50 with one in the region of the test devices 32 and 34 relative to this movable suction port 52 and at least two, in the example five, connected to the terminal 46 line sections 54, 56, 58, 60 and 62 has. The suction unit 48 is shown for clarity in FIG. 2 within the device 10, but in this embodiment is actually outside of the housing 14. In other embodiments, it may also be arranged as part of the device 10 within the housing 14. The line sections have suction openings arranged at different sections of the transport path 28 and directed onto the transport path 28, through which dust can be transported by value documents 12 transported along the transport path 28.

The components of the value-document processing device 10 in the region of the housing opening 38 are illustrated more precisely, but schematically in FIG. 2. The transport device 26 has a first section 64, which extends from a transition point 66 at the Vereinzier 18 to the second test device 34. Along the corresponding section of the transport path 28, value documents are conveyed by means of a belt transport. For transport along the first section 64, the transport device has driven belts 82 for the transport of documents individually delivered by the singler 18. The first section 64 is adjoined by a second section 68, which extends to the end of the second checking device 34, or slightly beyond, and is transported without straps in the value document. For transport along the second section 68, the transport device 26 has roller pairs in the region of the second test device 34. The second section 68 is adjoined by a third section 70, which extends to the output 22 and like the first section 64 for a belt transport is designed.

The transport path section formed by the first section 64, after the transition point 66 from the separator, has four arcuate sections 74, 76, 78 and 80, of which the bends 74, 76 and 78 also act as a bent section in FIG Sense of the invention fertil can be understood.

Both at the transition point 66 and at the four bends 74, 76, 78 and 80, the transport device 26 has transport rollers 84, 86, 88, 90 and 92, are guided over the respective belt 82 for transporting the documents of value and of which at least some are driven. In this case, the rollers 86, 88, 90 and 92 act as deflection rollers on which the documents of value are directed in a new direction, which takes place here by deflection of the belt 82, in other embodiments but also by direct contact of the documents of value can be done with the pulleys.

The transport device 26 has in the second section only partially shown in Fig. 13, partially driven transport rollers that transport the documents of value without a belt.

For the extraction of air and thus dust from the documents of value and in the air in the region of the transport path 28 serve the line sections 54 to 62, which are described in more detail below.

The suction openings of the first two line sections 54 and 56 and the suction openings of the third and fourth line sections 58 and 60 are arranged so that air and thus dust is sucked from two different sides of a value document transported along the transport path.

As shown in more detail in FIGS. 5 to 7, the first conduit section 54 has a tube 94 and at its end a first suction block 96 in which a cavity 97 connected to the end of the tube 94 is formed, which is in the direction of the transport path is closed by a plate 98 with directed onto the transport path 28, transversely to the transport direction T, staggered in this example or in rows, arranged suction openings 100 is completed.

The first suction block 96 and thus the suction openings 100 are arranged between the rollers 84 and 86 in the region of the transition point 66 between singler 18 and transport device 26. This allows the extraction of dust during singulation and the subsequent transition to the transport device 26 may arise. Due to the arrangement of the suction openings 100 over substantially the entire width of the transport path, an extraction can furthermore take place over the entire area of the value document.

The second line section 56 also has a tube 102 and at its end a guide means arranged at the bend 74 in the form of a first guide block 104. The guide block 104 has a channel 106 connected to the end of the tube 102 and at its transport path 28 and the pulley 86 facing side in

Transport direction extending, arranged transversely thereto ribs 108, between which the channel 106 opens into transverse to the transport direction suction ports 110 which are directed to the transport path. However, in the present exemplary embodiment, the guide device 104 carries parts of a value document only if they protrude above the transport belts, and thus prevents impairments of the transport. The actual deflection takes place through the belt 82.

Due to the arrangement of the suction openings 110 in the region of the bent portion 74 can be sucked by the taking place during the deflection deformation of the value document dust and abraded by slippage of the belt dust during its formation and therefore not distributed or at least not so much in the Housing 14, in particular in the field of testing equipment 32 and in particular also 34th

The third line section 58 illustrated in more detail in FIGS. 8 and 9 is constructed in principle like the first line section 54 and also has a tube 94 'and a second suction block 96' disposed at the end thereof in which one connected to the end of the tube 94 ' Hollow- raum 97 'is formed, which is completed in the direction of the transport path through a plate 98' with directed onto the transport path 28 suction openings 100 '. However, in contrast to the circular suction openings 100, the suction openings 100 'are slot-shaped, with the slots, with their longer side extending transversely to the transport direction, being arranged one behind the other in the transport direction.

The second suction block 96 'and thus the suction openings 100' are arranged between the deflection rollers 88 and 90 in the area between the bent sections or bends 76 and 78. This allows the extraction of dust, which has resulted from the further transport to the pulley 86.

The fourth line section 60 illustrated in more detail in FIGS. 8 and 10 has a similar construction to the second line section 56 and also has a tube 102 'and a guide device arranged on the bent section or bend 80 in the form of a second guide block 104'. The guide block 104 'also has a channel 106' connected to the end of the tube 102 'and ribs 108' extending in the transport direction on its side facing the transport path 28 or the deflection roller 92, between which the channel 106 'opens into suction openings 110' , which are directed to the transport path 28, but arranged transversely to this side by side. The guide device leads in the present embodiment, parts of a document of value in the above, however, only if they protrude above the conveyor belt, and thus prevents interference with the transport. The actual deflection takes place here by the belt 82nd The suction openings 100, 100 ', 110, 110' are preferably arranged less than 20 mm away from the plane of the transport path 28.

The fifth conduit section 62 (see Fig. 14) includes a tube 112 and a pivot portion 114 which is pivotable about an end of the tube 112 and for exhausting air and dust therein at the transition from the first conveyor belt transport section 64 the second transporting portion 68 for beltless transport and along the second checking device 34.

FIGS. 11 to 13 schematically show, in simplified form, the second test device 34 with a two-part optical sensor 116 and a two-part ultrasonic transmission sensor 118 and a holding device 120 for the second test device 34 and parts of the second section 68 of the transport device 26. While FIG. 11 shows the region of the test device 34 shows in a side view, in the transport direction of the transport device 26, in FIG. 12, the same region is rotated by 90 ° about an axis transversely to the transport direction. By way of example, the optical sensor 116 has two parts 122 and 124 which are arranged on opposite sides of the transport path. Part 122 serves, on the one hand, to remeasure measurement and, for this purpose, has an illumination device for illuminating a value document with optical illumination radiation and a detection device for detecting optical radiation emanating from a value document illuminated by the illumination radiation. The parts 122 and 124 are used for transmission measurement, wherein the part 124 detects a detection device for detecting illumination radiation of the part 122, which has passed through a value document. To protect the lighting device and the detection devices from contamination by dust, these are arranged in respective sensor housings, each a window 126 or 128 directed towards the transport path 28; the windows are designed and arranged such that both the illumination radiation and the detection radiation can pass through the window 126 or the transmitted illumination radiation through the window 128. The optical sensor 116 scans a value document transported past it line by line so that an image of the value document is present after the previous transport. To ensure proper operation of the sensor, it is necessary that the windows 126 and 128 is not or only slightly dirty. Likewise, the areas of the surfaces of the ultrasound transmission sensor 118 arranged on both sides of the transport path 28 should preferably not be contaminated by dust in order to ensure the best possible function.

The second test device 34 and the holding device 120 are constructed so that the test device 34, in particular also for cleaning purposes from an operating state in which an examination of documents of value by the second test device 34 is feasible, in a cleaning state in which the optical sensor 116, in particular the windows 126 and 128 of the optical sensor 116, are accessible, and is zurückversetzbar.

For this purpose, the holding device 120 is fixed to a fixed frame or a fixed plate 130 in the apparatus for processing banknotes 10; it has at least two parts, namely a first part 132 fixedly connected to the plate 130 and, as a second part, a swivel mount 134.

The first part 132 has receptacles for the sensors, in particular therefore a receptacle for the second sensor part 124, and along the transport path 28 at least two, preferably at least three by one not shown drive, for example, an electric motor and optionally a belt and / or gear transmission, driven rollers 136 of the second portion 68 of the conveyor 26, the axis substantially orthogonal to the transport direction and parallel to the longer side of the window 128 and the row direction the detection device of the second sensor part 124 extends. The first part 132 further has a guide plate 138, not shown in FIG. 12 for the sake of clarity, on which documents of value transported past can be guided on one side of the transport path 28. The guide plate 138 has openings in the region of the sensors, so that the guide plate 138 does not interfere with their function, and openings through which the driven rollers 136 engage. These openings are not shown in FIG. 14, however.

The second part, i. the pivot bracket 134 is pivotally connected to the first part 132 about an axis 140. Like the first part 132, the swivel mount has receptacles for the sensors, in particular a receptacle for the first sensor part 122, and rollers 142 of the second section 68 of the transport device 26, the number of which corresponds to the driven rollers 136 and whose axis of rotation is substantially orthogonal to the Transport direction and parallel to the longer side of the window 128 and the line direction of the detection device of the second sensor part 124 extends.

The swivel mount 132 also has a guide plate 138 ', not shown in FIG. 12 for the sake of clarity, on which it is transported

Value documents on the other side of the transport path 28 can be performed. The guide plate 138 'has openings in the region of the sensors so that the guide plate 138' does not interfere with their function, and openings through which the rollers 142 can engage. The swiveling holder 134 allows the second checking device 34 to be put into the two above-mentioned states.

11, the pivot mount 134 is oriented relative to the first portion 132 such that sensors of the inspection device 34 assume a position relative to each other and to the transport path 28 in which they can detect characteristics along the transport path 28 of transported value documents and Thus, an examination of value documents is feasible. Further, the guide plates 138 and 138 'at least approximately parallel to each other and form a narrow guide gap for the documents of value. Further, the driven rollers 136 and the rollers 142 are aligned with each other so as to pinch a value document coming out of the first section 66 of the transport device 26 and further transporting it along the transport path 28 as a roller transport. The rollers 136 and 142 therefore form roller pairs for a belt-less transport along the transport path section formed by the second section 68 of the transport device 26. In order to be able to ensure the transport of the value documents, the distance between the axes of rotation along the transport path 28 of successive pairs of rollers 136, 142 must be smaller in the transport direction than the dimension of the smallest value document, in the direction of which the transport of the value documents takes place in the transport system. If the value documents are transported parallel to their short edges (transversely), the distance must not be greater than the width of the smallest value document to be transported. If the value documents are transported parallel to their long edges (longitudinally), the distance must not be greater than the length of the smallest value document. Advantageously, the distance between see the axes of rotation about half the width or length of the smallest in the corresponding direction document of value.

In the cleaning state in Fig. 13, the pivot bracket 134 is pivoted away from the first portion 132 so that the sensors, such as the optical sensor 116, in particular its windows 126 and 128, are accessible for cleaning.

To move the swivel mount 134 and thus to change the state of the second test device 34 is an actuator, in the present example, a pneumatic cylinder 144 of a pneumatic system 146 of the device 10, provided one end to the plate 130 (or in another embodiment with the first part 132) and the other end is rotatably coupled to the pivot bracket 134. By changing the pressure in the pneumatic system 146, the distance between the ends of the pneumatic cylinder changes so that the pivot bracket 132 is pivotable by the eccentric linkage on the pivot bracket.

To compensate for the weight of the swivel mount 134 with the sensor parts, there is a spring 148, one end of which is eccentrically coupled to the swivel mount 132 and the other end to the frame or plate 130. In the operating position shown in Figure 11, the spring 148 is only slightly tensioned in the cleaning position in Fig. 13, however, strong.

The pneumatic system 146 (see Fig. 2) may in particular comprise a pressure source 150, for example a pump, and / or a controllable valve 152 connected to the or a pressure source via a pressure line and at least one connecting line to the pneumatic cylinder 144. To control the movement of the pneumatic cylinder 144, the control device 36 can control the pneumatic system, for example the pressure source and / or the valve 152, in order to change the pressure in the pneumatic system. By entering appropriate commands in the controller 36 so a user can operate the pneumatic system. However, it is also possible for the control device 36 to be designed to detect a transport disturbance during transport of value documents to be processed by means of corresponding transport sensors of the transport device and to switch off the transport device depending on the detection of a transport disturbance and the state of the second test device from the operating state to change to the cleaning state.

For extracting dust from the region of the transition from the first to the second transport device section, from the region of the second operating section of the transport device or the region of the second test device, the fifth line section 62 partially shown in FIG. 14 is provided via the tube 112 and the pivot portion or pivot arm 114 has a slot-shaped, divided by ribs suction port 154. The one end of the tube 112 is connected to the port 46, the other end is formed as a nozzle, on which the pivot portion or pivot arm 114 is inserted with an opening 156 which is connected via a not-shown channel portion in the suction port 154. The upper edges of the guide plates 138 and 138 'and the suction port 154 are formed so that the edges are largely sealed with the pivot portion so that sucked through the suction port 154 air, or by this with the air extracted dust predominantly, preferably substantially completely, from the area between the guide plates 138 and 138 'comes. In operation, when the second test device 34 is in its operating state, the pivot portion 114 is adjusted so that the suction port 154 with its longer side parallel to the transport direction, preferably very close, above that formed by the guide plates 138 and 138 ' Guide slot is arranged. In this way, air and in particular airborne dust from the area of the second section 68 of the transport device 26 and the area of the second checking device 34, in particular the windows 126 and 128, can be sucked off parallel to the plane of the value documents.

When the second tester 34 is set in the cleaning state, i. opened here, the pivoting portion 114 in a plane parallel to the transport path and transversely to the value documents in the second section 68 of the transport device 26 transversely to the direction of the line of the sensor 116, to the side pivoted so far that the second Prüfein- direction 34th More specifically, their windows 126 and 128 are accessible for cleaning purposes.

The suction line system 44, shown in part in Figs. 3 and 4, further comprises, in addition to the line sections, the hand cleaning section 44, a tube 158, a flexible tube 160 connected to the tube 158, and a flexible tube at the free end of the tube 160 Area of the second test device 34 has movable suction brush 162 with a suction opening 52 surrounded by bristles 164. Since the suction brush 162 and thus the suction opening 52 can be moved into the area of the second testing device 34, it can be used very well for extracting dust from the region of the second testing device 34 or from the latter. The connection of the five line sections 54 to 62 and the manual cleaning section 44 to the terminal 46 is as follows (see Fig. 3, 4 and 15).

The five line sections 54 to 62 open into a branching element 168, which merges the branches in a pipe section 169.

In order to distribute the negative pressure from the suction unit 48, the suction line system 44 has a distributor device 170 connected to the connection 46, the manual cleaning section 50 and-in this exemplary embodiment via the branching element 168 -the line sections 54 to 62 (see FIG. the at least between a manual cleaning position in which dust can be sucked through the hand cleaning section 50, and a factory cleaning position in the dust by at least two line sections, here the five line sections 54 to 64 can be sucked back and forth.

In this embodiment, the apparatus 10 is constructed so that the position of the distributor 170 is adjusted depending on the condition of the second tester 34 and / or a change in the condition of the second tester 34. Specifically, the adjustment is made so that the distributing device 170 is set in the manual cleaning position when the second checking device 34 is put in the cleaning state while the distributing device 170 is set in the operation cleaning position when the second checking device assumes its operating state is offset.

In the present exemplary embodiment, the distribution device 170 is designed in such a way that a common drive source for changing the supply Stands of the second test device 34 and to change the position of United Ver expensive device 170 is used.

The distribution device 170 shown in greater detail in FIG. 15 has a flange plate 172 in which two openings are formed, one of which is concealed in FIG. 15 and the other reference numeral 174. The branching member 168, more specifically, its tube portion 169, and the end of the tube 158 of the hand cleaning portion 50 are connected to the distributor 170, more specifically, its flange plate 172 so as to open into each one of the openings in the flange plate. For connection to the terminal 46 and the suction unit 48 is a flexible tube 176, one end of which is connected to the terminal 46 and the other end is connected to a movable flange 178. In Fig. 15, only the opening 174 to the hand cleaning section 50 is visible, the other opening connected to the branching element 168 is concealed by the flange element 178 and the tube 176 held thereon.

The flange 178 is slidably mounted on the flange plate 172 with its Flänschfläche on the flange of the flange plate 172 so that it between a position shown in Fig. 15, in which it is the end of the tube 176 with the branching element 168, preferably in the region used to connect the negative pressure used, and a position in which it connects the end of the tube 176 to the end of the hand-cleaning section 50, preferably tight in the range of negative pressures used, is swingable back and forth.

For pivoting the pneumatic system 146 is provided as a common drive source having a further pneumatic cylinder 180 and supplied by the pressure source 150 with pressure. This is with an end rotatably connected to the flange plate 172 and its movable by the pressure ram or other end eccentrically with the pivotable flange 178.

Thus, if the pressure in the pneumatic system is increased, the second checking device 34 is simultaneously set from the operating state to the cleaning state and the distributing device 170 is moved from the operating cleaning position shown in FIG. 15 into the manual cleaning position. Conversely, when the pressure drops, the second testing device 34 is simultaneously moved from the cleaning state into the operating state and the distributing device 170 is moved from the manual cleaning position into the operating cleaning position.

Does a user at the control device 36 so before an input to which the control device 36, the second test device 34 from the operating state into the cleaning state, in this example by the pressure source of the pneumatic system 146 controls so that they the pressure increases, the second test device 34 is automatically placed in the open cleaning state and sucked air through the hand cleaning section. Thus, a thorough cleaning of the second test device 34 and the environment of the device can be done simply by the suction brush 162 is suitably guided by a user.

In the manual cleaning position, suction therefore takes place only through the hand cleaning section 50, in the operating cleaning position only through the line sections 54 to 62.

A second embodiment in Fig. 16 differs from the first embodiment only in that the distributor 170 and the second test device 34 are driven differently and therefore also the Control device is modified. All other parts of the device are unchanged, so that the same reference numerals are used for these and the explanations to these apply to the first embodiment also here.

Instead of the pneumatic system with the pneumatic cylinders, separate drives 182, for example electric motors, for changing the state of the second checking device 34 and the position of the distributing device 170 are now provided. These are connected via control connections to the control device 36 'and controlled by this. The control device 36 'differs from the control device 36 only in that it controls not the pressure source of the pneumatic system, but the drives together, so that the same function as in the first embodiment is achieved.

A third embodiment in Fig. 17 differs from the first embodiment only in that the switching on of the suction by the hand cleaning section 50, more precisely, the adjustment of the position of the distributor, not in dependence on the state of the second test device 34, but from the position the cover member and / or a movement of the cover between the opening and the cover position takes place.

For this purpose, in the present exemplary embodiment, a common drive source is provided for moving the cover element and for changing the position of the distributor device. For this purpose, only the pneumatic system is changed compared to the first embodiment, so that the same reference numerals are used for the same components as in the first embodiment and the explanations to these also here gel- The pneumatic system 146 "only differs from the pneumatic system 146 in that it has a further pneumatic cylinder 184 having one end coupled to the housing 14 and the other end coupled to the cover member 40. By appropriate input to the control device 36 a user now by changing the control of the pneumatic system 146 'by means of the control device 36 simultaneously change the state of the second test device 34, move the cover 40 between its two positions and an extraction through the hand cleaning section on or off or a suction through the line sections - or turn on.

In this case, the further pneumatic cylinder 184 is coupled to the cover member 40 that when moving the cover member 40 in the open position, the state of the second test device changed to the cleaning state and the suction is switched by means of the line sections on suction by means of the hand cleaning section. As the cover member 40 moves in the other direction, the reverse changes occur in the condition of the test device 34 and the suction system, respectively.

Yet another embodiment differs from the previous embodiment in that a controllable by a control device drive for moving the cover is provided, and that the control means is changed in that it controls both the drive and the distributor. All other parts of the device are unchanged from the previous embodiment, so that the same reference numerals are used for these unchanged parts and the explanations apply accordingly here. For movement of the cover 40, an electric motor is now provided as a drive, which can be controlled so that it can reciprocate the cover 40 by means of a gear and a coupling element between said positions. The pneumatic system 146 'is therefore replaced by the pneumatic system of the first embodiment.

The control device differs from the control device of the preceding embodiment in that it is designed to control the drive for the cover member 40, and in particular on appropriate inputs of a user drives the drive for the cover member 40 and the pneumatic system 146, whereby common changes in position of the cover member 40, the state of the second tester 34 and the position of the distributor 170 are effected, so that overall the same function as in the preceding embodiment is achieved.

In still other embodiments, at least one of the conduit sections may include a plurality of suction ports disposed on opposite sides of the transport path. For example, two guide means could be arranged with the structure of the guide means 104 on opposite sides of the transport path and connected to the same pipe of the corresponding line section. This allows a simultaneous extraction of dust on opposite sides of a value document.

In further embodiments, at least one of the tubes of the suction line system may also be wholly or partially replaced by a hose or a channel. In particular, it is conceivable that part of such a Chen channel is also formed by a part of a base plate or the housing 14.

Yet another embodiment differs from the second embodiment in Fig. 16 in that the device only via the hand cleaning section, so that the distribution device is eliminated. The control device is now designed to switch on the suction unit when it puts the second checking device in the cleaning state, and to switch it off again when it puts the second checking device in the operating state.
