Description

The invention relates to a single sheet handling device for inputting and outputting rectangular single sheets into or out of a container. Such rectangular individual sheets are, in particular, banknotes that are automatically fed into the container for storage or automatically removed from the container for output.

From the documents US 4,616,817 , US 6,682,068 and WO 00/24662 Arrangements are known in which deposited banknotes are fed to individual storage compartments that cannot be separated from the arrangements. From the document DE 33 25 182 C2 Another arrangement for storing individual sheets in fixed storage compartments that cannot be separated from the arrangement is known, in which stacking wheels are used to feed the individual sheets into the storage compartments. Furthermore, a large number of arrangements for depositing individual sheets into a stack are known, in which the stacking direction is arranged vertically and the feed elements are arranged above the stack. Such orders are, for example, from the documents EP 0 714 078 B1 , DE 32 37 821 C2 and GB 2 301 092 A known. On the other hand, a large number of arrangements for removing individual sheets from a stack are known. In particular, the document discloses EP 0 364 790 a circumferential trigger element with a profiled surface. There are also so-called cash recycling devices known, in which deposited banknotes are fed to a storage compartment and are removed from this compartment again during later payouts. Such a cash recycling device with storage compartments that cannot be separated from the device is, for example, from the document EP 0 148 310 known.

From the document DE 199 04 540 A1 a banknote storage container for cash dispensers is known. Further is from the document US 6,889,897 B2 a banknote storage container is known, in which a large number of feed elements and alternatively a large number of separating elements are arranged in the banknote storage container itself, which is designed as a cassette. However, this has the disadvantage that these elements must also be present in replacement cassettes and space must be provided in the cassette itself for the feeding and separating elements, which is lost for the banknote storage. Furthermore, a disadvantage of arranging feeding and separating elements in the cassette is that they increase the weight of the cassette and thereby increase the transport effort for transporting the cassette. However, in order to enable the feeding of banknotes into a banknote container and the removal of banknotes from the same container, the feeding and separating elements must be positioned exactly to the stack surface or to the end face of the stack of banknotes located in the container in order to ensure reliable transport of banknotes into and out of the container to enable.Document JP 59 120756 U discloses a device for handling banknotes with a cash box that has feeding and separating elements arranged separately from the cash box. In the cash box there is a pressure carriage and circumferential belts arranged at the bottom of the cash box.

The object of the invention is to provide an arrangement with a container for holding rectangular individual sheets and with a single sheet handling device for inputting and outputting the individual sheets into or out of the container, in which a simply constructed unit can be separated from the feeding and separating elements of the individual sheet handling device container can be used.

This task is achieved by an arrangement with the features of patent claim 1. Advantageous developments of the invention are specified in the dependent claims.

By means of an arrangement with the features of claim 1, individual sheets can be fed to a container in a simple manner and individual sheets can be removed from the same container. By arranging the feed elements and the separating elements separately from the container, a simple construction of the container is possible and the weight of the container can be significantly reduced compared to an arrangement of feed elements and separating elements in the container. Such a single sheet handling device is particularly suitable for use in an ATM, with an operational exchange of full and/or empty containers taking place as required, so that for each container arranged in the ATM, at least one further exchange container is kept available for exchange against this container arranged in the ATM . It is therefore desirable that the containers can be manufactured with relatively little effort. By arranging This is possible in a simple manner if the feed elements and the separating elements are separated from the container.

It is advantageous if the feed elements position a single sheet to be fed to the container in front of the stack surface formed by an end face of the stack. As a result, this fed single sheet is subsequently the frontmost single sheet of the stack. The front or back of the fed single sheet subsequently forms the front side of the stack.

In a further development of the invention, at least some of the feed elements and at least some of the separating elements are designed and arranged in such a way that, at least in a feeding or separating operation of the single sheet handling device, they feed at least one single sheet located in a single sheet receiving area of the container through at least one opening in a front boundary wall contact through the single sheet receiving area. This makes it easy for the feeding elements and the separating elements to access the frontmost individual sheet of the stack or to an individual sheet to be fed.

Furthermore, in one embodiment of the invention it is provided that the single sheet handling device has at least one active drive for changing the position of a front boundary wall of the container designed as a flap, the drive controlling the movement of the container Flap initiated or effected in a feeding and/or separating position, in which a feeding and/or removal opening is released for feeding or removing the individual sheets. This allows the individual sheets to be easily transported into and out of the container via the released feed and/or removal opening.

This embodiment of the invention can be further developed in particular in that the active drive moves the flap into a rest position before or during the operational separation of the container from the feeding and separating elements, preferably before or during a removal process for operationally removing the container from an ATM , wherein the flap is arranged in the rest position such that the feed and / or removal opening is closed and preferably locked. When the flap is moved into the rest position, at least some of the individual sheets of the stack are preferably pressed into the individual sheet receiving area of the container. As a result, all individual sheets of the stack are securely arranged in the individual sheet receiving area when the container is separated from the feeding and separating elements. Arranging the flap in the rest position makes unauthorized removal of banknotes more difficult.

Furthermore, in this embodiment it is advantageous if the drive moves the flap at least from the feeding and/or separating position into the rest position and from the rest position is moved into the feeding and/or separating position when the operating mode changes from the feeding mode to the separating mode or when the operating mode changes from the separating mode to the feeding mode. As a result, at least the front individual sheets of the stack are pressed into the individual sheet receiving area and brought into a defined starting position for changing the operating mode or brought into a defined starting position for the subsequently intended operating mode.

Furthermore, in this embodiment it is advantageous if the single sheet handling device has engagement elements for actuating the flap when the container comes into contact with the elements of the single sheet handling device which are arranged separately from the container, wherein the drive activates the flap when moving into the feeding and/or separating position Engagement elements actively driven against a spring force for moving and / or holding the flap in the rest position. This makes it possible to arrange the drive separately from the container and to operate the flap safely via the engagement elements.

In a further development of the invention, at least one separating element has at least one separating wheel, preferably a suction roller with suction elements arranged on its outer surface for contacting a single sheet. It is advantageous if suction cups are provided on the outer surface of the suction roller which a single sheet sticks to the suction roller. Alternatively or additionally, the separating wheel can be a take-off wheel with an outer lateral surface having a profiling, the profiling preferably consisting of transverse ribs. With such separating elements, a simple and safe separation of the individual sheets of the stack located in the container is possible.

Furthermore, it is advantageous if the separating device has at least two separating rollers arranged on the same driven shaft, which have a uniform peripheral surface. The separating rollers are preferably arranged on the shaft in a spring-mounted manner, so that the separating rollers, at least in a separating operating mode, evenly contact the front or back of the first banknote arranged on the front side of the stack in order to avoid twisting of the banknote when separating and removing it. The separating rollers preferably have a profiled surface, with at least the surface of the separating rollers having a material with a high coefficient of friction. Furthermore, it is advantageous that the separating rollers have a profile, preferably transverse grooves or suction cups on the peripheral surface.

In the invention, it is advantageous to arrange the individual sheets one behind the other on their horizontal edge as a stack in the container. This allows a high packing density to be achieved. Furthermore, the container can have a relatively low overall height, allowing for multiple containers can be arranged one above the other in conventional ATMs or in conventional automatic safe deposit boxes. Furthermore, the containers can be transported lying down, which ensures that the containers can be easily stacked.

The container is preferably a closed, replaceable cassette. With such a closed cassette, unauthorized removal of individual sheets by people who come into contact with the cassette can be made more difficult or avoided, since removing individual sheets from the cassette requires manipulation of the cassette, which usually leaves visible traces, which means that the manipulation the cassette can be noticed and proven immediately. Furthermore, such a cassette offers the possibility of simply feeding banknotes to an ATM and removing banknotes from the ATM. The closed cassette means that no further outer packaging is required for transport, for example by a cash transport company.

Furthermore, it is advantageous if the container has a plurality of interconnected displaceable slats which, in a closed position, at least prevent unauthorized access to the flap, with a drive element or an engagement element automatically closing the slats before or when the container is removed from the feeding and separating elements brings the locking position. Such a separation occurs in particular when removing a container from an ATM or from an automatic machine Safe deposit box, for example when replacing the container. By arranging the slats in the closed position, direct access to the flap is not possible. This makes manipulating the flap more difficult because the slats would have to be removed beforehand. The interconnected slats are also known as roller shutters or blinds.

In the invention, it is particularly advantageous if at least the active drive elements for driving the separating elements and the active drive elements for driving the feed elements are not part of the container and are therefore separate from the container. As a result, these drive elements do not have to be provided once for each container but only for a container space provided by the individual sheet handling device. If at least one replacement container is provided, the effort required to produce the container can be significantly reduced. Furthermore, the containers are subject to greater wear and tear, so that when replacing a worn container, these drive units and any feed elements and/or separating elements provided in the container would each have to be replaced with the container, which requires considerable additional effort compared to the proposed solution.

Furthermore, in a further development of the invention, at least one actively driven limiting element is provided, which is movable in the stacking direction and the opposite stacking direction and the stacking space in the individual sheet receiving area variably limited by its position. The active drive of the limiting element, which can be implemented, for example, by an electric motor arranged in the container, makes it possible to enlarge and reduce the stacking space as needed in a simple manner. Furthermore, the stack located in the container can be compressed if necessary. Furthermore, with the help of the actively driven limiting element, it is possible to move the stack towards a feeding and/or separating area, so that the frontmost individual sheet of the stack comes into secure contact with the feeding and/or separating elements. By means of such a limiting element, the individual sheets can be held in a position in which they are arranged as a stack standing on their horizontal edge. The limiting element can be designed, for example, as a sliding carriage.

In a further development of the invention, a double sheet stripping element is provided on a transport path for further transport of the individual sheets removed with the aid of the separating element, which separates a second individual sheet removed from the stack together with a first individual sheet from the first individual sheet and holds it in the feed and removal area or back into a feed area and/or transported back into the container. This means that double deductions, ie the removal of two banknotes, can be reliably prevented even if two banknotes are stuck together.

It is advantageous if the double sheet stripping element comprises at least one stripping wheel arranged on a shaft and/or at least one stripping roller arranged on the shaft. The stripping wheel or the stripping roller are connected to the shaft in a rotationally fixed manner, with the shaft being stationary in the separating operation or being driven against the transport direction of a single sheet to be transported away. In feeding mode, the direction of rotation of the stripping wheel or stripping roller corresponds to the transport direction of a single sheet to be fed. Alternatively, the shaft can be a fixed shaft, with the stripping wheel or stripping roller having a freewheel in only one direction of rotation, so that rotation of the stripping wheel or stripping roller is possible without rotation of the shaft when feeding a single sheet into the feed area or into the container . As a result, the double sheet stripping element does not hinder the transport of the single sheet to be fed into the feed area.

Furthermore, the stripping wheel or the stripping roller can be driven via the shaft on which it is arranged with the aid of a drive unit, the direction of rotation of the stripping wheel or the stripping roller for stripping off the second individual sheet being opposite to the movement of the individual sheet to be removed.

In an advantageous first embodiment of the invention, the feed device can have at least one at least single-blade impeller as a feed element and also at least one drive unit for driving the at least include an impeller. The drive unit rotates the impeller when feeding a single sheet to be fed into the container in such a way that the wing presses against the end face of a stack of individual sheets located in the individual sheet receiving area of the container and presses at least some of these individual sheets at least temporarily into the individual sheet receiving area and creates a free feed area for positioning the Single sheet to be fed is generated in front of the front side of the stack. As a result, the individual sheet to be fed can be easily transported into the free feed area without its transport movement being hindered by excessive friction with the frontmost individual sheet or with the end face of the stack.

In this first embodiment of the invention, it is advantageous if a control unit controls the drive unit in such a way that the wing of the impeller is at a distance from the front edge of the fed single sheet during feeding and that the fed single sheet does not contact the wing during feeding. This means that the movement of the individual sheet is not hindered by contact with the wing. The individual sheet is therefore not deformed when fed, in particular not compressed, and can simply be positioned in front of the front of the existing stack.

It is advantageous to provide at least two impellers that have the same axis of rotation, preferably with one single shaft that can be driven with the aid of a drive unit of the feed device are connected in a rotationally fixed manner, the blades of the impellers preferably being at a lateral distance from one another and being aligned in the same way, that is to say protruding from the rotatable shaft at the same angle. The drive unit rotates the shaft and thus the impellers when feeding a further individual sheet in such a way that both blades press at a lateral distance from one another, ie parallel, against the end face of a stack of individual sheets located in the individual sheet receiving area of the container, so that at least some of these individual sheets be temporarily pressed into the individual sheet receiving area of the container at the contact points with the two wings. This allows a uniform gap, ie a feed area, to be created for positioning the further individual sheet in front of the end face of the stack. It is particularly advantageous to provide three, four, five or six impellers, which are arranged in a rotationally fixed manner on a common shaft, with all or only some of the vanes pointing in the direction of the stack depending on the size of the individual sheets of the stack when feeding another individual sheet press against the end face of the stack of individual sheets located in the individual sheet receiving area of the container and at least temporarily press at least some of these individual sheets into the individual sheet receiving area of the container. The blades of the impellers have a lateral offset from one another, so that the top of the stack, ie the end face of the stack, is contacted by the blades at several contact points that are arranged essentially parallel to the front edge or parallel to the rear edge of the individual sheet. Preferably the impellers are over the entire Width of a permissible sheet width for a single sheet to be fed arranged distributed. It is advantageous, in particular, to provide six impellers, with the same first distance being provided between the four inner impellers and the outer impellers having a second distance to the second or fifth impeller that is smaller than the first distance.

Furthermore, in the first embodiment of the invention, it is advantageous to additionally provide a sensor arrangement, preferably a light barrier arrangement, for detecting a sheet edge of a single sheet to be fed to the container with the aid of the feed device. The drive unit of the feed device starts the drive of the at least one impeller a preset time after the sheet edge of the individual sheet has been detected by the sensor arrangement, the sensor arrangement preferably detecting the front edge of the individual sheet. Before the drive of the at least one impeller is started, it is preferably in a basic feed position in which the vane is aligned essentially horizontally and pushes or pushes the end face of the stack into the individual sheet receiving area of the container as far as possible with the vanes. This creates a sufficiently large feed area, ie a sufficiently large inlet area, of a single sheet transported into the feed area via transport means, so that it can be positioned unhindered in front of the front side of the stack and subsequently forms the stack surface, ie the front side of the stack.

Furthermore, in the first embodiment of the invention, it is particularly advantageous if the enveloping circle of the wing of the impeller is selected and if the impeller is arranged in such a way that the apex of the enveloping circle is arranged at approximately the same height as the front edge of the largest possible one that can be fed to the container Single sheet when it is arranged in the single sheet receiving area of the container. As a result, the lowest possible height of the container can be achieved with a reliable function, since no installation space above the stack of notes is required, at least for the impeller.

Furthermore, in the first embodiment of the invention, it is advantageous to provide at least one inclined deflector, through which the front edge of a fed individual sheet is guided towards the end face of the stack and held on the stack, the inclined deflector having a lateral offset from the impeller and the inclined deflector preferably is spring-mounted. The inclined deflector thus ensures that even with a relatively wide feed area, a single sheet transported into this feed area rests at least with its front edge on the front side of the stack. Due to the resilient mounting of the inclined deflector, the inclined deflector is pressed towards the front side of the stack via the spring force, so that an individual sheet's front edge touches the inclined deflector when it enters the feed area, at least in the last part of the transport path, with the inclined deflector deflected against the spring force if necessary can be.

The end of the inclined deflector facing the end face of the stack presses against the front side of the individual sheet facing the oblique deflector and presses it against the stack located in the container or limits the maximum distance between the fed individual sheet and the end face of the stack already located in the container. Furthermore, the inclined deflector is deflected against the spring force when the stack moves further towards the separating elements in the separating operation, i.e. H. is moved out of the single sheet receiving area.

Furthermore, in the first embodiment of the invention, it is advantageous if the front region of the blade of the impeller has a curvature counter to the direction of rotation of the impeller when feeding the individual sheet. As a result, the end face of the stack located in the container is contacted with the outer curvature, whereby only a relatively small amount of force is required to move the wing past the end face of the stack and to push at least part of the stack into the individual sheet receiving area of the container. Furthermore, the curvature reduces the friction between the wing surface and the individual sheet arranged on the front side of the stack and avoids edges that scrape the surface of the individual sheet and can cause damage to the individual sheet. The curvature of the wing allows for a smooth and trouble-free process. The wing including the curved front area is not flexible but rigid, so that the wing and the curved front area of the wing at one Contact with the end face of the stack cannot be deformed or only slightly elastically deformed. The wing is therefore preferably rigid.

Furthermore, it is advantageous if the at least one impeller has a hub from which the at least one blade protrudes, the blade protruding essentially tangentially from the hub. The hub makes it possible to easily arrange the impeller on an axle or a shaft. Due to the tangential connection of the wing to the hub, the longitudinal axis of the wing runs obliquely to the axis of rotation, with the curvature in the front area of the wing being aligned in such a way that an axis intersecting the axis of rotation and running parallel to the longitudinal axis of the wing intersects the curved front area of the wing. As a result, even when two such wings are arranged tangentially to the hub, offset by 180° and with a vertical alignment of the wing axes, only a relatively narrow area is required for arranging these wings with a curvature, which means that with such a vertical arrangement of the wing axes the stack is up to the Separating elements can be pushed. Due to such a design of the impeller, only a relatively small amount of space is required for the impeller. If the longitudinal axis of the blade of the at least one blade is horizontally aligned, in which the blade contacts the end face of the stack, the impeller is in a basic feed position. If the blades are aligned vertically, ie the blade axes are aligned vertically, the blade wheel is in a basic removal position, since the blades are not needed to remove individual sheets from the container.

The individual sheets contact a take-off wheel or another separating element to remove at least one individual sheet from the stack. The longitudinal axis of the non-curved area of the wing is considered the wing axis.

In the first embodiment of the invention, it is further advantageous to provide at least two further impellers which are arranged on a common drivable shaft and whose blades move at least the rear edge of a single sheet fed to the container towards the stack when the shaft rotates when the fed single sheet is forward is positioned on the front side of the stack already in the container. As a result, in particular the lower part of the individual sheet can be moved towards the stack when the individual sheets are arranged vertically on their long side, whereby the individual sheet is then positioned on the front side of the stack and subsequently forms the front side of the stack. At least one area of the wings of the impellers is flexible and is elastically deformed as the wing passes in the lower area of the individual sheet, with the elastic deformation and additionally the rotational movement exerting a force on the lower area of the individual sheet towards the existing stack. The wings are preferably made of an elastic material. Furthermore, it is advantageous if the three blades are provided which protrude from a hub of the impeller at 0°, 90° and 180°, preferably tangentially. This means that the wings can be aligned by appropriate rotation of the shaft so that no wing protrudes into the transport path, so that a single sheet can be inserted into the Feed area can reach without it contacting one of the wings of the other impellers.

In an embodiment not part of the invention, the feed device has at least one rotating conveyor belt, the conveyor belt having at least one transport tab for receiving a region of a single sheet to be fed to the container. With such a conveyor belt, the individual sheet located in the transport tab can be guided in front of the stack located in the container, in which case no or only a relatively small feed space is required between a front flap of the container and the front side of the stack located in the individual sheet receiving area of the container.

Preferably, at least two, in particular three, conveyor belts are arranged next to one another, with the at least one transport tab of each conveyor belt being arranged at the same circulation position, so that a fed individual sheet is simultaneously guided into one transport tab of each conveyor belt arranged at a lateral distance from one another and is transported further in the transport tab until it is positioned in front of the front of the stack in the container. Preferably, the transport tab is connected to the conveyor belt on an edge transverse to the direction of rotation. Furthermore, it is advantageous if the transport tab extends from the edge along the conveyor belt. The other edges of the transport tab are not compatible with the Conveyor belt connected so that the transport tab protrudes tangentially from the curvature when the edge is arranged on a curvature of the conveyor belt. The transport tab preferably has essentially the same width as the transport belt. This means that the entire bandwidth can be used as a receiving area for the transport strap.

Furthermore, it is advantageous if the endless conveyor belt is deflected via at least one driven shaft and is driven in a transport direction with the aid of this shaft, the edge on which the transport tab is connected to the conveyor belt being provided on the front edge of the transport tab in the transport direction of the conveyor belt is.

It is particularly advantageous if the conveyor belt has two transport tabs, which are arranged offset by 180° on the outer circumference of the conveyor belt when the conveyor belt is arranged in a circle. However, the conveyor belt is preferably guided over two shafts, so that the conveyor belt does not have a circular circumference in the installed position. Furthermore, it is advantageous if at least the conveyor belt or the conveyor belt and the at least one transport tab have a hole in the circumferential direction of the endless conveyor belt for the engagement of a sprocket. Such a spiked wheel and such a perforation can prevent slippage between the drive shaft and the Conveyor belt can be avoided. This is particularly important if at least two conveyor belts are provided with a time offset from one another, each of which uses at least one transport tab to hold an area of a single sheet to be fed in order to permanently ensure a parallel alignment of the transport tabs.

Furthermore, in the embodiment not part of the invention, it is advantageous to provide a first, preferably rotatable, actuating element which, in a first operating mode for removing the individual sheet from the container, presses at least the rear edge of the transport tab opposite the front edge against the conveyor belt and/or the in a second operating mode for feeding a single sheet into the container creates a gap between the rear edge of the transport tab and the conveyor belt and / or this gap is enlarged. This ensures that an area of a single sheet to be fed is guided securely into the transport tab or that when a single sheet is removed from the container, a transport tab protruding from the conveyor belt does not protrude into the transport path for transporting the single sheet away. In the first operating mode, the actuating element can release a feed and removal area by the pressure of the rear edge of the transport tab on the conveyor belt caused by the actuating element and / or the actuating element in the second operating mode can open the transport tab in the input and output area in such a way that a feeder can enter - and removal area transported single sheet into the transport tab and in the transport tab is positioned in a position in front of the first individual sheet of the stack, which forms the end face of the stack in the container.

Furthermore, it is advantageous to provide at least one pressure element, preferably at least one impeller, which presses a fed individual sheet and/or at least some of the other individual sheets of the stack present in the container into the container.

Furthermore, it is advantageous to provide at least one stripping element that is arranged in such a way that the stripping element transports an individual sheet in front of the end face of the stack with the help of the transport tab in a position in front of the end face of the container in a further rotational movement of the conveyor belt in the feed and removal area The stack is held back and thereby pulled out of the transport tab. This allows the individual sheet to be easily positioned in front of the front of the stack.

Furthermore, it is advantageous to provide at least one inclined deflector through which the front edge of a supplied note and/or the upper region of a supplied note is guided towards the stack. The inclined deflector has a lateral offset from the circulating conveyor belt, whereby the inclined deflector is preferably resiliently mounted. Furthermore, it is advantageous if the inclined deflector also serves as a scraper element, with the device then having a combined inclined deflector and scraper element.

In a non-inventive embodiment, the feeding device and the separating device have at least one combined stacking and separating wheel as a combined feeding and separating element. This stacking and separating wheel has chambers that form a stop on the bottom of the chamber for the individual sheets to be fed to the container. Furthermore, the stacking and separating wheel comprises at least one separating element which can be moved out of the peripheral surface of the stacking and separating wheel. In a further development of the stacking and separating wheel according to the non-inventive embodiment, the stacking and separating wheel has two chambers, which are preferably arranged at a distance of 180°. By providing multiple chambers, a chamber can be positioned more quickly in the transport path of individual sheets to be fed. It is particularly advantageous to provide three stacking and separating wheels arranged at an axial distance from one another on a common stacking and separating wheel shaft. The stacking and separating wheels are preferably driven via the stacking and separating wheel shaft. This can ensure that the chambers are aligned parallel in such a way that a fed individual sheet is guided into one chamber of each stacking and separating wheel, each with one area. Coordinating multiple drive units is therefore not necessary.

In a stacking mode for taking over the individual sheets from a transport path for depositing the individual sheets in the container, the at least one stacking and separating wheel is preferably positioned so that a region of the fed individual sheet can be inserted into the chamber. A drive unit rotates the stacking and separating wheel parallel to part of the feed movement of the individual sheet, with the individual sheet remaining in the chamber and with a rotational movement of the stacking and separating wheel a control element actuates a clamping element assigned to the chamber, so that the clamping element holds the individual sheet in the Chamber held via a clamp connection. A cam disk is preferably used as a control element.

In an advantageous development, a separating operating mode is further provided in which a control element moves the at least one separating element out of the peripheral surface of the stacking and separating wheel at least for a preset period of time, with a drive unit rotating the stacking and separating wheel so that the separating element is moved out of the peripheral surface contacts the frontmost individual sheet of the stack located in the container, which forms the front stack surface. By turning the stacking and separating wheel, the frontmost individual sheet is moved and fed to at least one transport element for further transport of the individual sheet. It is advantageous that a control element has one Separating lever is controlled in such a way that the separating element is moved outwards, ie away from the axis of rotation of the separating and stacking wheel. This control element can in particular comprise a cam.

Furthermore, it is particularly advantageous to provide a stripping element which stops the movement of an individual sheet located in the chamber of the stacking and separating wheel, a clamping connection produced by the clamping element between the stacking and separating wheel and the individual sheet being released when the stripping element Movement of the individual sheet stops. The release is in turn controlled by the or another control element, which preferably comprises at least one cam. It is particularly advantageous if a drive unit continues to rotate the stacking and separating wheel after the stripping element has stopped the direction of movement of the individual sheet. This means that the fed single sheet is simply pulled out of the chamber.

Furthermore, it is advantageous to provide at least one inclined deflector through which the front edge of a fed single sheet is guided towards the stack. The inclined deflector has a lateral offset from the stacking and separating wheel, with the inclined deflector preferably being resiliently mounted. It is particularly advantageous to provide a combined inclined deflector and scraper element.

In the non-inventive embodiment, it is further advantageous to provide a sensor arrangement, preferably a light barrier arrangement, for detecting a sheet edge of the individual sheet to be fed to the container with the aid of the stacking and separating wheel and for the drive unit to drive the at least one stacking and separating wheel for a preset time after detecting the edge of the sheet after detecting the individual sheet by the sensor arrangement. It is particularly advantageous if the sensor arrangement detects the front edge of the individual sheet, since then there is only a small distance between the detection area of the sensor arrangement and the receiving chamber of the stacking and separating wheel positioned to feed the individual sheet.

A further disclosed aspect relates to a money deposit and withdrawal device, with one of the single sheet handling devices shown above and with a container, wherein the container can be removed from the money deposit and withdrawal device with an individual sheet that may be in the container or with several individual sheets that may be in the container and where the single sheet handling device with the driven feed elements of the feed device and the driven separating elements of the separating device remains in the money deposit and withdrawal device. It is advantageous if the container in the money deposit and withdrawal device can be exchanged for a similar container.

A third disclosed aspect relates to a system with at least one cash deposit machine and at least one cash payout machine, in which the cash deposit machine has at least one feed device with feed elements for feeding individual sheets sheet by sheet and for storing these individual sheets in a stack of individual sheets in a replaceable container. The cash dispensing machine has at least one separating device with separating elements for removing the individual sheets of the stack one sheet at a time from the same container. The container is removed from the cash deposit machine and inserted into the cash payout machine. At least some of the individual sheets fed to the container in the cash deposit machine are removed from the container again in the cash payout machine. The feeding elements and the separating elements are not part of the container but are preferably part of the cash deposit or cash withdrawal machine. It is advantageous if at least the cash deposit machine has an authenticity checking unit for checking the authenticity of the deposited banknotes.

A fourth disclosed aspect relates to a rotating conveyor belt with a first elastically deformable material strip and with a second elastically deformable material strip. A first end of the first strip of material is connected to the inside of the second strip of material via a first strip-shaped first connection region which extends transversely to the direction of travel of the conveyor belt. A region of the second material strip with the first end of the second material strip extends beyond the first connection region and forms a transport tab for receiving a portion of a single sheet between the transport tab and the first strip of material. It is advantageous to connect a second end of the second material strip via a second strip-shaped connection region of the inside of the first material strip which extends transversely to the direction of rotation of the conveyor belt. It is advantageous if a region of the first material strip with the second end of the first material strip extends beyond the second connection region and forms a second transport tab for receiving a region of a single sheet between the transport tab and the second material strip. The transport tabs are preferably arranged offset by 180° on the outer circumference of the conveyor belt. The first and second strips of material preferably have the same dimensions.

Furthermore, it is advantageous if the first and second material strips have a hole for engaging a sprocket. This enables the conveyor belt to be driven without slipping by the sprocket wheel.

It is particularly advantageous if this perforation runs along the circumference of the conveyor belt approximately in the middle of the conveyor belt. This means that only one spiked wheel or roller with spikes needs to be provided in order to drive the conveyor belt safely without slipping. The engagement of the spikes of the spike wheel approximately in the middle of the conveyor belt ensures that the conveyor belt does not distort when driven. Furthermore, the conveyor belt can be positioned axially by the spiked wheel, whereby a displacement of the conveyor belt in the direction of the shaft ends of a deflection shaft, ie drifting away, is avoided.

The first and second material strips are preferably film strips, for example polyethylene film strips. The film strips have a uniform material cover that is in the range between 0.001 mm and 0.5 mm. Such polyethylene film strips and other suitable film strips can be welded together in particular using a welding process, such as an ultrasonic welding process, in order to produce in particular the first and second connection areas.

In Figure 1 10 shows a safe 10 arranged in an ATM with a total of four replaceable cassettes 12a to 12d arranged one above the other. Each cassette 12a to 12d is assigned a separating and stacking module 14a to 14d, with the help of which banknotes present in the respective cassette 12a to 12d are removed and alternatively banknotes are fed to the respective cassette 12a to 12d with the help of the separating and stacking module 14a to 14d can. The banknotes are in the cassettes 12a to 12d are stored as a stack, with the banknotes standing on their long side in the cassettes 12a to 12d. With the help of transport elements 16a to 16d, the banknotes can be fed to the separating and stacking modules 14a to 14d and removed from these separating and stacking modules 14a to 14d. With the help of the transport elements 16a to 16d, which in particular include belts, rollers and / or switches, a transport path 18 is formed, via which banknotes are transferred from a transfer point 20, via which the banknotes are fed to the safe 10 or issued from the safe 10 a selected separating and stacking module 14a to 14d are transported. Furthermore, a banknote removed from one of the cassettes 12a to 12d with the aid of the separating and stacking module 14a to 14d assigned to this cassette can be fed to the transport elements 16a to 16d and along the transport path 18 via the transfer interface 20 to a control panel of the ATM arranged above the safe 10 can be transported further with at least one input and output compartment.

Usually, banknotes to be deposited are stored in bundles in the input and output compartments and separated in the upper part of the ATM so that they are fed to the safe 10 one after the other along the transport path 18 via the transfer interface 20. Furthermore, the banknotes removed from the cassettes 12a to 12d are transported one after the other along the transport path 18 via the transfer interface 20 out of the safe 10 and then formed into a stack or Bundles stacked. This bundle is then output via the input and output tray. Furthermore, the ATM has a suitable operating unit and other elements, such as a card reader and, if necessary, security devices for authenticating an operator.

Alternatively, the in Figure 1 shown safe 10 with the cassettes 12a to 12d, the separating and stacking modules 14a to 14d and the transport elements 16a to 16d can also be used in an automatic safe deposit box.

The banknotes are preferably transported at a transport speed of ≥ 1.2 m per second, preferably ≥ 1.4 m per second, along the transport path 18 and removed from the cassettes 12a to 12d at a corresponding speed or taken with these cassettes 12a to 12d supplied at an appropriate speed.

In Figure 2 a separating and stacking module 30 is shown according to an embodiment of the invention. In particular, the separating and stacking module 30 can Figure 2 as a separating and stacking module 14a to 14d Figure 1 be used. Elements with the same structure and/or the same function are marked with the same reference numerals.

In addition to the separating and feeding elements of the separating and stacking module 30, elements of the cassette 12a used for the stacking and separating functions are shown. The separating and stacking module 30 has, as separating elements, three take-off wheels 32 arranged next to one another, which are arranged in a spring-mounted manner on a take-off wheel shaft 34 and are connected to this shaft 34 in a rotationally fixed manner. At the in Figure 2 In the side view shown, only one of the take-off wheels 32 is visible. Furthermore, the withdrawal wheel shaft 34 is resiliently mounted at one end, so that it can be moved horizontally at this shaft end and is pressed with the help of the spring force towards the front side of the cassette 12a and thus against the front side of a stack 36 of banknotes arranged in the cassette 12a when this Stack 36 is arranged in a separation position. A first bank note 38 to be fed in the direction of arrow P0 is fed into a feed area 46 in front of the stack 36 located in the cassette 12a with the aid of drive wheels 44 arranged on a main drive shaft 42.

Furthermore, a guide element 48 is provided that partially surrounds the drive wheels 44 and that guides the movement of the banknote 38 around the drive wheels 44. Furthermore, a pressure roller 50 is provided, with the help of which the banknote 38 is pressed against the drive wheels 44 for transport. Furthermore, two stripping rollers 52 are arranged on a shaft 53, which in the present exemplary embodiment have a freewheel, so that they rotate in accordance with a rotational movement of the drive wheels 44 in the direction of the arrow P1 shown, even without rotation of the shaft 53. When the drive wheels 44 are driven in the opposite direction to that in Figure 2 As shown by the arrow P1, there is no rotation of the stripping rollers 52. The stripping rollers 52 preferably have a peripheral surface made of rubber or another material with a relatively high coefficient of static friction, so that when two banknotes get into the gap between the drive wheel 44 and the stripping roller 52, the one facing the stripping roller 52 Banknote is stripped from the banknote facing the drive wheel 44 and is not transported further to the pressure roller 50. This can ensure that when banknotes are removed from the cassette 12a, only one banknote is removed at a time.

The separating and stacking module 30 also has, as a feed element, several impellers 54 arranged on a drive shaft 62, each of which has two vanes 58, 60 projecting tangentially from a hub 56 of the impeller 54. The vanes 58, 60 are connected to the drive shaft 62 in a rotationally fixed manner, so that the vane wheels 54 can be driven with the aid of a drive unit via this shaft 62 in the direction of rotation of the arrow P2 shown. The ends of the wings 58, 60 are curved against the direction of rotation, so that when they rotate in the direction of arrow P2, they contact the end face of the stack 36 with their curved outside. In the present exemplary embodiment, the stack 36 comprises several banknotes with a relatively small first height, one banknote of which forms the front side of the stack 36, and several banknotes of a larger second height, one banknote of which forms the back of the stack 36.

The impeller 54 is in Figure 2 shown in a basic stack position in which a horizontally aligned wing 60 of the impeller 54 presses against the end face of the stack 36 and presses the banknotes of the stack 36 out of the feed area 46 into the cassette 12a. In this basic stacking position of the impeller 54, the banknote 38 is transported into the feed area 46. When the banknote 38 is transported into the feed area 46, the withdrawal wheel 32 is additionally driven in the direction of the arrow P6, ie in the feed direction of the banknote 38. If the front edge of this banknote 38 falls below a preset distance from the wing 60, the impeller 54 is rotated via the drive shaft 62 so that the front edge of the banknote 38 does not contact the wing 60.

The separating and stacking module 30 further comprises a total of four inclined deflectors 64, which in the present exemplary embodiment are pressed against the end face of the stack 36 with the end facing the stack 36 with the aid of a pre-tensioned spring 65. Due to the oblique arrangement of the inclined deflectors 64, the upper region of the banknote 38 is moved towards the end face of the stack 36 when it comes into contact with the inclined deflector 64.

Five further upper impellers 54 are arranged on the shaft 62 and are connected to it in a rotationally fixed manner, so that the shaft 62 serves as a drive shaft for these six impellers 54 in total. An in Figure 2 Visible lower impeller is designated by reference number 66. Furthermore, there are Figure 2 individual elements of the cassette 12a shown as e.g. B. a note withdrawal flap 68, which is in Figure 2 is shown in an open state and which has been moved into this open position with the aid of drive elements arranged separately from the cassette 12a. Furthermore, there are Figure 2 Springs, not shown, are provided which exert a force on the note return flap 68 in the direction of its closed position.

The separating and stacking module 30 has a pressure device 45 which contacts a banknote 38 positioned in the feed area 46 in front of the end face of the stack 36 and presses this banknote 38 onto the end face of the stack 36 at least at the contact points. The pressure device 45 is designed so that it contacts the banknote 38 in its lower half when it is positioned in front of the end face of the stack 36. The pressure device 45 can comprise at least one anchor of a pull or push magnet designed as a pressure pin or a pressure pin coupled to the anchor.

Furthermore, two cassette impellers 72 arranged on a drive shaft 71 are provided on the bottom of the banknote receiving area of the cassette 12a, which are connected in a rotationally fixed manner to the drive shaft 71 together with pulleys for deflecting belts 70 arranged on the bottom of the banknote receiving area of the cassette 12a. Furthermore, a gear (not shown) is arranged on this drive shaft 71, which is connected in a rotationally fixed manner to this drive shaft 71 and via which the drive shaft 71 is driven by a drive unit arranged separately from the cassette 12a can be driven when another gear coupled to the drive unit is in engagement with this gear arranged on the drive shaft 71. These gears are brought into engagement when the cassette 12a has been inserted into receptacles provided in the safe 10 and is in the operating position for feeding and removing banknotes.

With the help of the cassette impellers 72 and the belts 70, at least part of the banknote stack 36 located in the banknote receiving area of the cassette 12a is transported away from the feed area 46, at least in the lower area of the banknotes of the stack 36, so that fed banknotes 38 with the help of the upper impeller 54, with the help the inclined deflector 64 and/or with the help of the note retraction flap 68 can be pressed into the banknote receiving area of the cassette 12a during the closing process. After the banknote 38 has been fed into the feed area 46, that is, when its rear edge is no longer in the area between the drive wheel 44 and the pressure roller 50, the lower impeller 66 is rotated so that at least one wing 74, 76, 78 of the lower impeller 66 is the rear edge and/or presses the lower area of the banknote 38 against the front side of the stack 36. This pressing of the lower area with the help of the lower impeller 66 takes place essentially simultaneously with the movement of the banknote 38 towards the stack 36 caused by the inclined deflector 64.

Furthermore, the separating and stacking module 30 includes a light barrier arrangement 39, which detects the front edge of a fed banknote 38 in the area between the drive wheel 44, so that the impeller 54 is driven based on the time of arrival of the front edge of the fed banknote 38 and a preset delay time the drive shaft 62 is started. The light barrier arrangement 39 comprises a prism arrangement for twice deflecting a light beam emitted by a light source, the light source and a light sensor for detecting the light beam emitted by the light source being arranged on the same side of the transport path for feeding and removing a banknote 38. The prism arrangement is arranged on the opposite side of the transport path. This ensures particularly reliable detection, since the light beam crosses the transport path of the banknotes twice. Furthermore, a simple, compact arrangement of the light source and the light sensor on only one side of the transport path is possible.

Furthermore, the lower impeller 66 has been rotated further. Furthermore, the separating and stacking module 30 includes a stripping element 75 in order to remove any banknotes 38 that adhere to the surface of the drive wheel 44 and guide them into the feed area 46. The stripping element 75 is preferably pressed against a stop with a spring force and is thereby held in the position shown.

In Figure 3 is that in Figure 2 Separating and stacking module 30 shown is shown, the feed elements 52, 54 and the banknote 38 transported into the feed area 46 being shown in a second feed position, which is different from that in Figure 2 differs from the basic stack position shown.

Banknote 38 is at the in Figure 3 shown feed position compared to that in Figure 2 position shown has been transported further into the feed area 46. Due to the already related with Figure 2 The described control of the drive of the impeller 54 has been driven via the drive shaft 62 in the direction of the arrow P2, so that it now has the in Figure 2 position shown. This ensures that a distance is maintained between the front edge of the banknote 38 and the wing 60, so that the fed banknote 38 does not contact the wing 60 and the feeding movement of the banknote 38 is not affected by contact with the wing 60.

Furthermore, the lower impeller 66 is rotated further, so that the wing 74 of the lower impeller 66 approaches the rear edge of the supplied banknote 38 and subsequently presses the rear edge or the lower region of the supplied banknote 38 against the stack 36. The vanes 74, 76, 78 project tangentially from a hub of the lower impeller 66, preferably at 0°, 90° and 180°. The blades 74, 76, 78 of the impeller 66 are made of an elastic material, preferably a rubber and/or plastic material manufactured and preferably curved in the direction of rotation of the lower impeller indicated by arrow P4. As a result, when the lower impeller 66 rotates in the direction of arrow P4, the wings 74 to 78 press with a relatively large force against the lower region of the fed banknote 38 and then deform in order to move between the front lower edge of the stack 36 and the hub of the lower one Impeller 66 to be pulled through. The wings 74 to 78 protrude from the hub of the impeller 66 in such a way that when the arrow P4 rotates, they only have to be pivoted to the hub by a relatively small angle in order to at least partially rest on the peripheral surface of the hub.

In Figure 4 is a further schematic representation of the separating and stacking module 30 according to the Figures 2 and 3 shown, wherein the feed elements 54, 66 and the fed banknote 38 are shown in a third feed position. In this third feed position, the upper impeller 54 is further rotated in the direction of arrow P2.

In Figure 5 is a schematic representation of the separating and stacking module 30 according to the Figures 2 to 4 shown, wherein the feed elements 54, 66 and the fed banknote 38 are shown in a fourth feed position. Opposite the in Figure 4 In the third feed position shown, the upper impeller 54 has been rotated further in the direction of arrow P2, so that the vane 58 is pivoted into the feed area 46 and subsequently into the in Figure 2 shown basic stack position rotated further is, in which the front curved area of the wing 58 presses against the fed banknote 38 and presses it together with other banknotes of the stack 36 into the banknote receiving area of the cassette 12a. In the lower area of the fed banknote 38, the three wings 74 to 78 are guided past the rear edge of the fed banknote 38 until they are back in the in Figure 2 shown basic stacking position are arranged. Furthermore, the lower region of the banknote 38 is pressed against the end face of the stack 58 by the pressure device 45, as a result of which fluttering of the banknote 38, which is caused in particular by the wings 74 to 78 guided past, is reduced.

The note retraction flap 68 has a plurality of openings through which the upper impeller 54, the inclined deflector 64 and the withdrawal wheel 32 pass and, depending on the operating state of the separating and stacking module 30, contact a banknote 38. Further openings in the note retraction flap 68 are provided for the further withdrawal wheels 32, the further upper impeller wheels 54 and the further inclined deflectors 64, so that these, in the same way as already explained for the feeding and separating elements 32, 54, 64, can also hold the banknote 38 can contact through the note retraction flap 68. In the open position of the note withdrawal flap 68, a feed and removal opening is present at least over a width of the widest feedable bank note 38, which is marked by the arrow P5. A banknote 38 to be fed reaches the feed area 46 via this feed and removal opening. In the same way, one from the cassette 12a closes The banknote 38 to be removed is transported through the feed and removal opening to the drive wheels 44 and further transported to the transport elements 16a with the aid of the drive wheels 44, which are then driven in the opposite direction to the direction of the arrow P1.

In Figure 6 is a further schematic representation of the separating and stacking module 30 according to the Figures 2 to 5 shown, wherein the feed elements and the separating elements as well as the banknote stack 36 arranged in the cassette 12a are shown in a separating position for withdrawing a banknote 38 from the banknote stack 36 present in the cassette 12a. The blades 58, 60 of the upper impeller 54 are connected via the drive shaft 62 into one Figure 6 The basic stack position shown has been rotated and remain in this basic stack position during the entire separation process for removing and transporting a banknote 38 from the cassette 12a.

With the help of a displacement carriage 82 driven by an electric motor 80, the stack 36 is moved into a separating position towards the withdrawal wheel 32, so that the end face of the stack 36 or the banknote 38 forming the end face of the stack 36 against the lateral surface of the withdrawal wheel 32 and against the Surface of the additional take-off wheels 32 arranged parallel to the take-off wheel 32 is pressed. By moving the stack 36 towards the take-off wheel 32, the inclined deflector 64 is pivoted about the axis of rotation 63, whereby the spring 65 which generates the pressing force of the inclined deflector 64 is pre-tensioned or further pre-tensioned becomes. To remove the banknote 38 forming the front side of the stack 36, the withdrawal wheel 32 is rotated in the direction of the arrow P7 with the aid of a drive unit, which is opposite to the direction of rotation of the withdrawal wheel 32 marked with the arrow P6 Figures 2 to 5 is directed. As a result of this rotation of the withdrawal wheel 32, the frontmost banknote 38 of the stack 36 is pushed or transported downwards past the stripping rollers 52 into the area between the drive wheels 44 and the pressure roller 50. The surfaces of the drive wheels 44 and the take-off wheels 32 preferably have a relatively high coefficient of friction. Preferably, the surfaces of the take-off wheels 32 and the drive wheels 44 are formed of rubber or other material with similar coefficients of friction. In addition, the surface of the trigger wheel 32 is structured by transverse grooves. These transverse grooves can create greater adhesion between the surface of the withdrawal wheel 32 and the banknote 38 to be moved downwards.

To remove or further transport a banknote 38 that has been moved downwards with the help of the withdrawal wheels 32, the drive wheels 44 are driven in the direction of arrow P8. The lower impeller 66 is positioned in a basic separation position so that its wings 74 to 78 do not protrude into the transport path for the removal and further transport of the banknote 38.

The transfer carriage 82 has axles 84, 86, each of which extends laterally from the transfer carriage 82 to the stack 36 delimiting side walls of the cassette 12a, with guide wheels 92, 93 being provided at the ends of the axles, which engage in guide rails 88, 90. The guide rails 80, 90 are formed in or on the side walls.

In Figure 7 is an arrangement with the separating and stacking module 30 according to Figures 2 to 6 with further elements of the cassette 12a for storing the banknotes and with a drive for actuating the note withdrawal flap 68, the note withdrawal flap 68 being shown in the illustration Figure 7 is shown in an open position.

A drive unit 96 moves a thrust element 98 via gear stages 100, 102 in the direction of arrow P10. The gear stages 100, 102 each produce a reduction. The driven gear of the gear stage 102 engages in a rack 104 formed on the thrust element 98 for displacing the thrust element 98. The thrust element 98 also has elongated holes 106, 108 through which guide bolts (not shown) protrude, the displacement range of the thrust element 98 being limited by these guide bolts and the elongated holes 106, 108. The thrust element 98 also has an incline 110. In Figure 7 the thrust element 98 is shown in a position in which no further displacement in the direction of arrow P10 is possible due to the already mentioned limitation of the displacement range. With the help of the thrust element 98, it can be pivoted about the axis of rotation 112 Lever 114 has been pivoted. By pivoting the lever 114, the note retraction flap 68 has been moved away from the end face of the stack 36, which means that one is already in connection with the Figures 2 to 5 explained feed and separation opening P5 is opened. By pivoting the lever 114 into the in Figure 7 In the position shown, a spring 116 provided for retracting the note retraction flap 68 is tensioned, which exerts a restoring force on the note retraction flap 68. This restoring force is at least partially transferred from the note retraction flap 68 to the lever arm 118. As a result of this restoring force, the second lever arm 120 in the present exemplary embodiment is pressed from below against the thrust element 98. The slope 110 of the thrust element 18 is designed as a wedge-shaped slope, whereby the thrust element 98 is also referred to as a wedge slide. Below in connection with Figure 8 Closing the note retraction flap 68 will be explained in more detail.

In Figure 7 a drive shaft 122 driven by the motor 80 for moving the displacement carriage 82 and a gear 124 connected to the shaft 122 in a rotationally fixed manner at one end of the drive shaft 112 are also shown. The gear 124 engages in a rack 120 formed on the lower guide rail 90 and connected in a stationary manner to the cassette 12a. Alternatively to the arrangement shown, the gear 124 may be combined with one of the guide rollers 92, 94 for engagement with a rack formed on the cassette 12a or may replace it.

Furthermore, in Figure 7 In the arrangement shown, a further sensor arrangement 126 is provided in addition to the light barrier arrangement 39 already mentioned above. The sensor arrangement is intended for monitoring the feed area 46 and in the present exemplary embodiment is designed as a transverse light barrier. With the help of the transverse light barrier 126, banknotes 38 can be detected if they are in the feed area 46.

Furthermore, a drive unit 128 and a gear stage 130 are shown for driving the drive shaft 42, on which the drive wheel 44 is arranged. In the present exemplary embodiment, the drive units 128, 96, 80 are designed as electric motors, preferably as stepper motors or as DC motors, although some of the drive units can also be designed as stepper motors and another part as DC motors.

In Figure 8 is the arrangement according to Figure 7 shown with a closed note withdrawal flap 68. To close the note retraction flap 68, the push element 98 has been moved in the direction of arrow P11 with the help of the drive unit 96 and the gear stages 100, 102. As a result, the lever 114 has been pivoted via the force introduced into the note return flap 68 by the spring 116 after a rotatable guide roller 134 arranged at the end of the lever arm 120 has been guided upwards on the slope 110 during the displacement movement in the direction of arrow P11. As a result, the lever arm 118 is also pivoted counterclockwise about the axis of rotation 112, so that the Note retraction flap 68 is rotated about an axis of rotation 136 and the removal and feed opening P5 is closed at least to such an extent that the removal of a bank note from the stack 36 is not possible or only possible with great difficulty.

In Figure 9 a section of the cassette 12a for storing banknotes is shown after the cassette 12a has been separated from the separating and stacking module 30. The cassette 12a is for separating from the feeding and separating elements of the stacking and separating module 30 in the direction of arrow P12 (see Figure 8 ) has been separated by pulling the cassette 12a out of an opening in the safe 10. The note retraction flap 68 has previously been pivoted into its closed rest position by an active drive with the aid of the drive unit 96 by a corresponding movement of the push element 98. Until the note retraction flap 68 is not arranged in the rest position, the cassette 12a is locked against being pulled out.

Alternatively, when the cassette 12a is moved in the direction of the arrow P12, the note retraction flap 68 is pivoted automatically via the spring force of the spring 116, since even when the cassette 12a moves in the direction of the arrow P12, the guide roller 134 of the lever arm 120 is on the slope 110 of the push element 98 is guided along so that the lever 114 is pivoted by the spring force of the spring 116 and the note retraction flap 68 is closed. Furthermore, the cassette 12a has a plurality of interconnected slats 138a to 138g for closing the end face 140 of the cassette 12a on. The slats 138a to 138g are connected to the adjacent slats in such a way or are designed in the connection area in such a way that a relative pivoting of the slats 138a to 138g about the axes of rotation 142a to 142e is possible in a limited angular range, so that the slats guided laterally in guide rails 144 138a to 138g are guided along a curved path specified by the guide rails. The slats 138a to 138g are moved to an area below the banknote receiving area of the cassette 12a when the inserted cassette 12a is in a working position. In the working position, the feeding and separating elements can contact a banknote 38 arranged on the front side of the stack 38 through the openings in the note withdrawal flap 68. In the closed state, the slats 138a to 138g cover both the essentially vertical end face 140 of the cassette 12a and an area starting from the end face 140 below the note withdrawal flap, so that the entire feed and removal area is completely covered by the slats 138a to 238g, when the cassette 12a is removed from the safe 10.

Moving the slats 138a to 138g into the in Figure 9 The closed position shown as well as the displacement of the slats 138a to 138g into an open position is preferably carried out via engagement elements when the cassette 12a is pushed in and pulled out into the safe 10 or out of the safe 10. When pushed in, at least one in the safe 10 then preferably engages stationary engagement element in at least one engagement opening of at least one lamella 138a to 138g. Through the When the engagement element engages in the engagement opening, the slats 138a to 138g are opened like a roller shutter or a blind when the cassette 12a is further pushed into the safe 10, ie in a direction opposite to the arrow P12, so that the end face 140 of the cassette 12a and an area is opened on the underside of the cassette 12a from the end face 140 of the cassette 12a. This lower region preferably extends to the end face of the banknote stack 38, so that in particular the wings 74 to 78 of the lower impeller 66 can contact the banknote stack 36 as described.

Due to the at least one engagement element that projects into the engagement opening, the slats 138a to 138d are pushed back into position when the cassette 12a is moved in the direction of arrow P12 Figure 9 shifted to the closed position shown, in which no access to the note withdrawal flap 68 or the stack of banknotes 36 located in the cassette 12a is possible. The slat 138g is at least partially covered by a base plate of the cassette 12a, so that the cassette 12a is completely closed by moving the slats 138a to 138g in the closed position. Thus, in this closed position, there are no openings through which banknotes or parts of banknotes could be removed.

In Figure 10 is a three-dimensional view of the drive elements for driving cassette impellers 72 arranged in the cassette 12a near the end face 140 and the shaft 53 with the lower impellers 66 arranged thereon and the stripping rollers 52 arranged thereon are shown. The drive shaft 71 is driven by an electric motor 146 via several gear stages 148 to 154, on which a gear 158, two toothed pulleys 160a, 160b and several cassette impellers 72a to 72e are arranged in a rotationally fixed manner. The floor belts 70a, 70b, designed as toothed belts, are guided and deflected via the pulleys 160a, 160b. As already described, the straps 70a, 70b contact the underside of the banknotes arranged standing on the straps 70a, 70b, which are present in the stack 36 in the cassette 12a, or at least some of these banknotes. In the previous figures, only the impeller 72e has been shown and referred to as the impeller 72 and the belt 70b as the belt 70. In the description, similar elements that are present multiple times in a specific arrangement are provided with the reference number itself if they are only shown once in the corresponding figure and with an additional consecutive small letter if the element is present multiple times in a figure is.

Only the shaft 71 and the elements 158, 160a, 160b, 72a to 72e arranged thereon are part of the cassette 12a. The remaining elements of the gear stages 148, 150, 152, 154 and the electric motor 146 are arranged separately from the cassette 12a. If the cassette 12a is in an operating or working position inserted into the safe 10, a gear of the gear stage 154 engages with the gear 158 arranged on the shaft 71 of the cassette 12a, so that the shaft 71 is driven and rotated when the output shaft of the motor 146 rotates.

In Figure 11 a three-dimensional representation of the drive elements for driving the note retraction flap 68 is shown. As already in connection with Figure 7 explained, the note retraction flap 68 is driven via an electric motor 96, which moves the thrust elements 98a, 98b in parallel via gear stages 100, 102 and a rack 104a, 104b formed on the thrust elements 98a, 98b. The rotational movement initiated by the motor 96 is transmitted via a shaft 166 and a gear 103 arranged at the other end of the shaft 166, which is in engagement with the rack 104a. This converts the driving rotational movement into a linear movement, through which the thrust elements 98a, 98b are displaced in parallel. In addition to the elongated holes 106a, 108a for guiding the movement of the pushing element 98a, the pushing element 98a has an opening 162 through which further elements of the separating and stacking module 30 can be carried out. Furthermore, the push element 98b has, in addition to the elongated holes 106b, 108b, a further opening 164 through which further elements of the separating and stacking module 30 can be guided. The lever arms 118a, 118b contact the note retraction flap 68 on opposite sides, so that this note retraction flap 68 is simultaneously opened or closed via the ends of the lever arms 118a, 118b when the push elements 98a, 98b are moved in parallel.

In Figure 12 is a three-dimensional representation of a lower 55 and with transmission elements for driving this impeller shaft 55. In addition to the lower impellers 66a to 66e, two stripping rollers 52a, 52b are arranged on the shaft 55. The lower impellers 66a and 66b are arranged on a sleeve 168a which is pushed over the shaft 55 and is freely rotatable relative to the shaft 55 and is connected in a rotationally fixed manner to this sleeve 168a. A gear 170a is also connected to this sleeve 168a in a rotationally fixed manner, so that the sleeve 168a can be driven independently of the shaft 55 via the gear 170a. At one end of the shaft 55, a double gear 172 is arranged on the shaft so that it can rotate freely. This double gear 172, together with other gears 174, 176 and together with a belt drive 178, serves to reduce the drive speeds of a drive unit 175. The rotational movement is transmitted from the gear 176, which is arranged in a rotationally fixed manner on a drive shaft 180, to the drive shaft 180 and from this drive shaft 180 via further gears 182, 184, 186 are transferred to the gears 170a, 170b, 170c which are non-rotatably connected to the sleeves 168a, 168b, 168c.

At the end of the shaft 55 opposite the gear 172, a further gear 186 is arranged, which is connected to the shaft 55 via a freewheel, so that a rotary movement of the stripping rollers 52a, 52b in the direction of the arrows P20 P22 is possible when the shaft 55 is not is driven via the gear 186 in the direction of the arrows P20, P22. To prevent double withdrawal, ie to prevent two banknotes from being withdrawn at the same time the container 12a, the stripping rollers 52a, 52b are also driven in the direction of rotation of the arrows P20, P22 via the shaft 55 and the gear 186. In other embodiments, the gear 186 can be connected to the shaft 55 in a rotationally fixed manner, which means that the freewheel can be dispensed with. Then, when feeding a banknote 38 into the feed area 46, the stripping rollers 52a, 52b are to be driven by a drive unit via the gear 186 and the shaft 55 in the direction of the arrows P20, P22.

In Figure 13 is a three-dimensional representation of separating elements for removing a banknote 38 from the cassette 12a and for further transport of the removed banknote 38. The already mentioned three withdrawal wheels 32a, 32b, 32c, which are connected in a rotationally fixed manner to the drive shaft 34 and which are resiliently mounted on this shaft 34, are driven to withdraw the banknote 38 arranged on the front side of the stack 36. The shaft 34 is connected to a drive unit, not shown, via a magnetic coupling 188, whereby the connection to the drive unit can be established or separated as required by the magnetic coupling 188. This separation option via the coupling 188 is particularly useful if the drive unit for driving the shaft 34 drives further elements of the separating and stacking module 30 and/or further transport elements 16a to 16d and the take-off wheels 32a to 32c are not always intended to carry out a rotary movement, when the other elements are driven. The drive wheels 44a to 44n are arranged on the main drive shaft 42. Between the drive wheels 44d, 44e, 44f, 44g and between the drive wheels 44h, 44i, 44j, 44k each have a retaining element 190a to 190f arranged. The retaining elements 190a to 190f protrude like fingers from a shaft 194 to which they are connected in a rotationally fixed manner. With the help of a pivoting arrangement for rotating the shaft 194 by just a few degrees, the retaining elements 190a to 190f can be moved out of the spaces between the drive wheels 44d to 44g and 44h to 44k with their end remote from the shaft 194, so that they move out of the envelope surface around them Drive wheels 44b to 44k come out and are pressed against the surface of the stripper rollers 52a, 52b. The banknotes present between the stripping rollers 52a, 52b and the retaining elements 190a to 190f are thus pressed by the retaining elements 190a to 190f against the stripping rollers 52a, 52b to prevent a double withdrawal. The pivoting arrangement includes a pull magnet 192 as a drive unit.

The drive shaft 34 is driven via the magnetic clutch 188 and the gear 189 arranged at one end of the shaft 34. The opposite end of the shaft 34 is pressed towards the stack of notes 36 using a pressure device 195. The pressure device 195 further comprises a pressure sensor which detects at least one position of the end of the drive roller 34 held in the pressure device 195. Due to the resilient mounting of the take-off wheels 32a to 32c, which are preferably arranged on a common sleeve 196, the sleeve 196 being resiliently mounted on the drive shaft 34, the take-off wheels 32a to 32c can be aligned parallel to the end face of the stack with a desired preset pressure force 36 can be pressed so that there is no diagonal trigger the banknotes 38 to be removed from the cassette 12a. The take-off wheels 32a to 32c are arranged on the sleeve 196 in a rotationally fixed manner, the sleeve 196 being connected to the drive shaft 134 in a rotationally fixed manner. Due to the resilient mounting of the sleeve 196 on the drive shaft 34, however, a joint pivoting of the take-off wheels 32a to 32c is possible, so that they align themselves parallel to this end face by pressing the take-off wheels 32a to 32c on the end face of the stack 36 and thereby a parallel take-off of the enable banknote 38 present on the front side of the stack 36.

The drive shaft 42 is driven via the gear 198 arranged at one end of the drive shaft 42 via drive elements of a central distribution module arranged in the safe 10, which drives further transport elements 16a to 16d of the transport route 18. This gear 198 is designed as a double gear and drives the drive side of the magnetic clutch 188. This means that no separate drive is required for driving the drive wheels 44 and the take-off wheels 32 in the separating and stacking module 30.

The separating and stacking module 30 according to the embodiment of the invention creates a module separation between the cassette 12a and the feeding and separating elements. As a result, a simply constructed, inexpensive cassette 12a can be used, with the feeding and separating elements being arranged in the safe 10 or in the ATM and when the cassette is removed 12a remain in the safe 10 or in the ATM. The cassette 12a can be used in a first ATM for depositing and withdrawing banknotes (cash recycling) and can be used as a pure withdrawal cassette 12a when the same ATM is reconfigured or when this cassette 12a is used in another ATM. It is advantageous to arrange the cassette 12a in such a way that the end face of a stack of banknotes 36 present in the cassette 12a is arranged vertically, ie that the stacking direction or the stacking depth runs horizontally. However, the separating and stacking module 30 and the cassette 12a can also be arranged so that the stacking direction or the stacking depth is vertical, with the end face of the stack 36 on which banknotes can be removed from the stack 36 and further banknotes can be fed to the stack 36 , then arranged horizontally at the top of the stack 36.

The upper two-wing impellers 54 with rigid wings 58, 60 are designed and arranged in such a way that the envelope circle of the wings 58, 60 ends at the top with approximately the largest permissible note height and, in the basic horizontal stacking position, also a stack 36 formed from the smallest permissible banknotes 38 supports or pushes further into the cassette 12a. During a feeding process for feeding a banknote 38, a wing turnover takes place, ie before the banknote 38 is fed, the first wing 60 contacts the end face of the stack 36 and after the banknote 38 has been fed, the second wing 58 contacts the end face of the stack 36. This takes place a dynamic triggering of the wing folding depending on the The front edge of the banknote 38 to be fed is detected by the light barrier arrangement 39, the turnover time being selected such that a banknote 38 that has just been fed is shifted towards the stack 36 or is struck towards the stack 36 with the outer curvature of the curved wing end. The turnover time is preferably set depending on the size of the banknote 38 supplied, that is to say it varies depending on the size. The inclined deflectors 64 guide a fed banknote 38 away from the center of the wing 60 or 58 of the impeller 54 towards the front side of the stack 36. The wings 74, 76, 78 of the lower impeller are tangentially connected to a hub of the impeller 66, the front one Area of the wings 74, 76, 78 each has a curvature. The curvature is designed such that the wing tips move ahead of the remaining part of the wings 58, 60 in the direction of rotation of the impeller 54 when a banknote 38 is fed.

The main drive shaft 42 with the drive wheels 44 is continuously driven via an electric motor for driving the transport elements of the transport path 18, the drive shaft 34 with the take-off wheels 32 arranged thereon being able to be selectively coupled or decoupled to the drive of the drive wheels 44 via the magnetic coupling 188. The continuous drive of the drive wheels 44 and the optional drive of the withdrawal wheels 32 are carried out by a central drive for the transport elements 16a to 16d arranged in the safe 10, which has a large torque reserve, so that even banknotes that are difficult to separate, e.g. B. adhering, freshly printed banknotes or notes with polymer film, separated with the help of the take-off wheels 32 and can be transported with the help of the drive wheels 44. The withdrawal wheels 32 are driven via the switched magnetic clutch 188 until the banknote has reached the detection range of the light barrier arrangement 75 arranged in the area of the drive wheels 44. This has the advantage that the overall process for withdrawing and further transporting the banknote 38 does not get out of step in the event of delays in the withdrawal or further transport, for example as a result of banknotes sticking together, as can occur with rigidly mechanically coupled separating drives. Rather, when a sheet edge of the banknote 38 to be removed arrives, the removal is simply continued, so that the control for the removal of the banknote 38 is event-controlled depending on the event "arrival of the sheet edge of the withdrawn banknote 38 in the detection area of the light barrier arrangement".

1. 1. Vor der Stirnseite des Banknotenstapels 36 muss ein freier Zuführbereich (freier Raum) 46 für die zuzuführende Banknote 38 gegen den Stapeldruck des Stapels 36 erzeugt und vom Stapeldruck des Stapels 36 freigehalten werden.
2. 2. Die Hinterkante einer zugeführten Banknote 38 muss zum Stapel 36 geführt werden, sobald sie den Kontaktbereich zwischen Antriebsrad 44 und Andruckrolle 50 bzw. zwischen Antriebsrad 44 und Abstreifrolle 52 verlassen hat.

For a trouble-free feeding of a banknote into the cassette 12a, the following conditions must be met, at least in the embodiment of the invention:

1. 1. In front of the end face of the stack of banknotes 36, a free feed area (free space) 46 must be created for the banknote 38 to be fed against the stacking pressure of the stack 36 and kept free from the stacking pressure of the stack 36.
2. 2. The trailing edge of a fed banknote 38 must be guided to the stack 36 as soon as it has left the contact area between the drive wheel 44 and the pressure roller 50 or between the drive wheel 44 and the stripper roller 52.

The stack pressure already mentioned is determined in particular by the stack thickness, the condition and properties of the banknotes arranged in the stack 36 and the position of the displacement carriage 82. For almost the entire period in which the banknote 38 to be fed is transported into the feed area 46, the stack 36 is pushed out of the feed area 46 with the help of the upper impellers 54. For this purpose, several impellers 54 are arranged on the drive shaft 62, which is arranged horizontally in the embodiment of the invention, distributed over the maximum permissible note width. The drive shaft 62 with the impellers 54 is preferably driven with the aid of a stepper motor, the drive shaft 62 being rotated by 180° each time a banknote 38 is fed. As already mentioned, the impeller wheels 54 are driven in such a way that the front edge of a fed banknote 38 does not contact the wing 58, 60 projecting into the feed area 46, but rather that there is a minimum distance between the front edge of the fed banknote 38 and the wing 58, 60 by suitable control of the stepper motor to drive the drive shaft 62. The wings 58, 60 have a relatively small width. In the present exemplary embodiment they have a width of 6 mm. In the pauses between the feeding of two banknotes, the impellers 54 are in the basic stacking position, in which the wing 60 protruding into the feed area 46 contacts the stack of notes 36 below the smallest permissible note height. In the present exemplary embodiment, the smallest permissible note height is 58 mm.

Furthermore, this is already discussed in connection with Figure 1 pressure element 45 described in the in Figure 5 shown feed position activated so that it contacts the fed banknote 38 in the lower half and presses it against the end face of the stack 36 already in the cassette 12a. The pressure element 45 in particular comprises a push magnet, the armature of which is moved when the push magnet is activated in such a way that one end of the anchor or a further element connected to one end of the anchor presses against the front or back of the banknote 38 facing the pressure element 45 and the Banknote 38 moves at least in the contact area towards the front side of the already existing stack 36 and presses it against this front side of the existing stack 36. This avoids in particular a so-called fluttering of the lower region of the supplied banknote 38 during contact or after contacting the lower edge or the lower region of the supplied banknote 38 as a result of contact with the wings 72 to 76 of the lower impeller 66.

The rotation time of the upper impeller 54 when rotating through 180 ° is preferably preset so that the fed banknote 38 is pushed by the second wing 58 towards the end face of the stack 36 and pressed against it, as soon as the fed banknote 38 has left the contact area between the drive wheel 44 and the pressure roller 50. The inclined deflectors 64 in particular ensure that relatively large banknotes, which are arranged as a stack 36 in the cassette 12a, do not bend above the wing 60 which presses against the end face of the stack 36 in the basic stack position and into the area above the wing 60 located in the basic stack position protrude. Without these inclined deflectors 64, the banknote arranged on the front side or several banknotes of the stack 36 could be pulled upwards by the wing 60 when the impeller 54 rotates. When feeding a banknote 38, the lower impeller 66 is preferably rotated together with the drive wheels 44, the lower impeller 66 being drivable or rotatable independently of the counter-rotating shaft 55, as already described. When the banknote 38 is transported into the feed area 46, the flexible wings 74 to 78 of the lower impellers 66 are elastically deformed and wound onto the hub of the respective impeller 66, so that a spiral arrangement of the wound wings 74 to 78 takes place. As soon as the rear edge of the banknote 38 leaves the contact area between the drive wheel 44 and the pressure roller 50 or between the drive wheel 44 and the stripper rollers 52a, 52b, the first wing 74 to 78, which reaches under the rear edge of the banknote, strikes against the lower region of the banknote 38 and presses this lower area upwards and against the stack 36.

The lower impellers 66 are also driven via a separate stepper motor, which has a freewheel drives the shaft 55 with the stripping rollers 52a, 52b arranged thereon, so that the stripping rollers 52a, 52b are also driven in the feeding direction of the banknote 38 when a banknote 38 is fed and thereby at least do not hinder the feeding of the banknote 38. As already mentioned, the lower impellers 66 each have three blades 74 to 78, the base points of which are not evenly distributed over the circumference and leave a gap of 180 ° in the present exemplary embodiment. To separate, ie to remove, a banknote 38 from the cassette 12a, the lower impeller 66 is then aligned so that no wing 74 to 78 protrudes into the transport path for transporting the withdrawn banknote 38. This position of the wings 74 to 78 of the lower impeller 66 are in Figure 6 shown.

As explained, the wings 74 to 78 are not arranged centrally on the hub of the lower impeller 66 but rather protrude tangentially to the sides. This allows the wings 74 to 78 to carry out the described elastic deformation with relatively low stress on the material. In particular, the foot zone of each of the wings 74 to 78 connected to the hub of the impeller 66 is not angled as much when the wings 74 to 78 are placed against the hub when the impeller 66 rotates as when the wings 74 to 78 are connected to the center in the center Hub.

The note retraction flap 68 is in its in Figure 8 shown rest position preferably locked with the help of locking elements on the cassette housing in order to When transporting the cassette 12a, ensure that the note retraction flap 68 remains in the rest position. The movement of the note retraction flap 68 is controlled via gates which are provided in or on the outer walls of the cassette 12a. Guide elements connected to the note retraction flap 68 are in engagement with the links, with these guide elements preferably being locked with the aid of the locking elements. As a result, the note retraction flap 68 must remain in this rest position in the locked state as long as the locking elements are in engagement with the guide elements.

With the help of the already related to the Figures 7 , 8th and 11 The drive of the note retraction flap 68 described above then moves it into the essentially vertical position Figure 7 shown position pivoted, in which it releases the feed and removal opening i5.

The procedure for feeding a banknote will be briefly summarized below. After inserting the cassette 12a and after opening the note retraction flap 68, the displacement carriage 82 is moved synchronously with the floor belts 70 in the direction of the separating and stacking module 30. As a result, the displacement carriage 82 presses the banknotes present as a stack 36 in the note receiving area of the cassette 12a against the withdrawal wheels 32. As already explained, the withdrawal wheel shaft 34 is resiliently mounted on one side, with the aid of a sensor arrangement being used to deflection the non-driven shaft end of the drive shaft 34 is recorded analogously and/or digitally. With the help of the detected deflection, pressure optimization can be carried out when separating, ie when withdrawing banknotes.

After the displacement carriage 82 has pressed the stack of banknotes 36 present in the cassette 12a against the withdrawal wheels 32 with a preset maximum pressure, the direction of movement of the displacement carriage 82 is reversed and a preset retraction path is covered. Due to different note qualities, the required stacking space is different, particularly in the case of a stack of notes 36 with a relatively large number of banknotes, so that with a constant retraction path of the displacement carriage 82, a different pressure force from the notes onto the feed and separating elements of the separating and stacking module 30 occurs. In a first step, the displacement carriage 82 is moved a first distance away from the separating and stacking module 30. An indirect stack pressure determination is then carried out, with the upper impeller 54 being rotated from the basic separating position into the basic stacking position. Parallel to this rotational movement of the upper impeller 54, the displacement carriage 82 is moved further away from the separating and stacking module 30, at the same time the bottom belts 70 being driven in such a way that they move the banknotes standing on the belts 70 away from the separating and stacking module 30. This continues until the vanes 58, 60 of the upper impeller 54 have reached the basic stacking position or until the sensor arrangement 126 no longer detects any banknotes in the detection area.

During the described positioning process of the transfer carriage 82, the upper impeller 54 is driven with the aid of the stepper motor with reduced stepper motor current and a frequency that is reduced compared to the normal drive frequency. The permissible note pressure can therefore be determined by the torque of the stepper motor. In principle, stepper motors are unsuitable for torque control because a stepper motor skips control steps when a limit torque is exceeded, with the torque falling to zero when control steps are skipped. The torque is only built up again after four more steps. In order to prevent backward movement, a freewheel is arranged on the drive shaft 62. During the setting process, a pulsating control signal is used to control the stepper motor, which increases with each pulse up to the value applicable to the selected low frequency. This is repeated until the basic feed position or basic stacking position of the impeller 54 is reached, in which the non-curved region of the wings 58, 60 is aligned essentially horizontally.

Alternatively, a DC collector motor or a brushless DC motor (DLBC) can be used instead of the stepper motor. Due to available torque controls, such motors are better suited for adjusting the stack pressure and thus better for positioning the transfer carriage 82. However, position detection and control for detecting the angular position is then required Drive shaft 62 or the upper impeller 54 is required. Such a positioning control is relatively complex.

After adjusting the stacking pressure of the stack of notes 36 on the wings 58, 60 of the upper impeller 54, a positioning check is carried out in the lower area of the banknotes arranged as a stack 36. For this purpose, a sensor arrangement 126 designed as a transverse light barrier is provided, which is arranged at the limit of the maximum required feed area 46 in the so-called stack foot zone and thus monitors the area in front of the end face of the stack 36. With continuously rotating lower impellers 66, the bottom belts 70 and the impellers 72 arranged in the cassette 12a are also driven to transport the stack of notes 36 from the feed area 46 into the note receiving area of the cassette 12a until the light barrier arrangement 126 no longer detects a bank note in its detection area. The feeding of banknotes 38 then takes place with continuously rotating drive wheels 44 and continuously rotating lower impellers 66. The withdrawal wheels 32 are rotated at least temporarily via the magnetic coupling 188, in particular in order to prevent the front edge of the fed banknote 38 from getting caught on the lateral surface of the withdrawal wheels 32 .

With each transaction, up to 200 banknotes 38 can be fed into the cassette 12a. For each banknote 38 fed, the transfer carriage 82 is synchronized with the floor belts 70 moved by a preset retraction path away from the separating and stacking module 30, ie moved back in the cassette 12a. If this preset retraction path is not sufficient, after a banknote 38 has been fed, it will at least partially remain in the detection area of the monitoring light barrier arrangement 126 and be detected by it, since this banknote 38 could not be pushed sufficiently far into the banknote receiving area. The preset retraction path is not sufficient in particular when used banknotes 38 have a greater resulting note thickness in the stack due to their deformation. The preset retraction path of the transfer carriage 82 is therefore not sufficient to provide sufficient stacking space for the banknotes being fed. If the light barrier arrangement 126 detects a banknote in the detection area, the displacement carriage 82 is moved away from the separating and stacking module 30 by an additional retraction path.

Furthermore, intermediate compression is provided, since if the preset retraction movement of the displacement carriage 82 is too large or if the banknotes are uneven, a relatively poor filling level in the cassette 12a would be achieved. For this purpose, an intermediate compression process is provided before a further transaction if more than 150 banknotes, a maximum of 200 banknotes, have been supplied. The process corresponds to the process already described for adjusting the stack pressure after feeding the cassette 12a or before positioning the upper impeller 54 in the basic stack position. Intermediate compression results in a preset generous amount Increments of air gaps created when the displacement carriage 82 is withdrawn are at least partially removed from the stack 36 by compressing the entire stack 36.

After separation, in which the non-bent areas of the wings 58, 60 of the upper impeller 54 are aligned essentially vertically, the impeller 54 is rotated again into a basic stacking position in which the non-bent areas of the wings 58, 60 of the upper impeller 54 are essentially horizontally aligned. In this basic stack position, all banknotes in the stack 36 are arranged in the cassette 12a, so that the cassette 12a can be removed from the safe 10 as soon as the note withdrawal flap 68 has been pivoted inwards. As already mentioned, the note retraction flap 68 is pivoted into the rest position with the help of the in Figure 11 shown drive for the note withdrawal flap 68. If the cassette 12a should be able to be removed without further preparation, especially when the ATM is in a powerless state, the note withdrawal flap 68 must always be pivoted into the rest position if no feeding or removal process is currently being carried out.

In Figure 14 is a three-dimensional representation of a separating and stacking module 200 according to an embodiment not part of the invention with three conveyor belts 202 to 206 arranged next to one another, each with transport tabs 202a to 206a. With the help of the transport tabs 202a to 206a, banknotes are fed into the cassette 12b. Furthermore, the separating and stacking module 200 two withdrawal wheels 208, 210, with the help of which the banknotes present as a stack 36 in the cassette 12b are individually removed from the cassette 12b, ie the banknotes are separated.

The endless conveyor belts 202 to 206 are guided over upper deflection rollers 212 to 216, which have lateral guides in the manner of a pulley for laterally guiding the endless conveyor belts 202 to 206. The deflection rollers 212 to 216 are connected in a rotationally fixed manner to a drive shaft 218, which can be driven via an electric motor 220. The shaft 218 is driven via a belt drive 222. Furthermore, a lower deflection roller 224 to 228 is provided for each conveyor belt 202 to 206, which are arranged freely rotatable on a drive shaft 230 for driving the take-off wheels 208, 210 and have suitable axial limiting elements in be held in their axial position on the drive shaft 230. The endless conveyor belts 202 to 206 and the transport tabs 202a to 206a have a perforation with several holes arranged at equal distances from one another along the circumference of the endless conveyor belt 202 to 206. The upper deflection rollers 212 to 216 have protruding spikes that are complementary to the perforations of the conveyor belts 202 to 206 and which engage in the perforation, so that both further lateral guidance and a slip-free drive of the conveyor belts 202 to 206 take place.

The conveyor belts 202 to 206 are driven in the direction of arrow P50. With the help of intervention elements, each of which is preferably designed as a single-blade impeller 232 to 240, a gap can be created or enlarged between the rotating conveyor belt 202 to 206 and the downwardly opened transport tabs 202a to 206a, so that the conveyor belts 202 to 206 have a basic feed position.

In the same way as described in the embodiment of the invention, a banknote 38 is fed via the drive wheels 44. By opening the transport tabs 202a to 206a with the help of the wings 232 to 240, a feed area is created between the rotating conveyor belt 202 to 206 and the an stack of banknotes 36 resting on the outside of the transport tabs 202a to 206a are generated. A banknote 38 to be fed is transported into this feed area. As a result, an area of this banknote 38 is inserted into the transport tabs 202a to 206a or guided between the transport tabs 202a to 206a and the conveyor belts 202 to 206. After areas of the fed banknote 38 are positioned in the transport tabs 202a to 206a, the conveyor belts 202 to 206 are driven in the direction of arrow P50 at essentially the same rotational speed as the speed at which the fed banknote 38 is driven with the help of the drive wheels 44 the transport tabs 202a to 206a have been conveyed in. Furthermore, stripping elements (not shown) are provided which prevent the banknote arranged with areas in the transport tabs 202a to 206a from further circulation with the conveyor belts 202 to 206 and thereby pull it out of the transport tabs 202a to 206a when the conveyor belts 202 to 206 are driven further.

These stripping elements are arranged so that the banknote 38 pulled out of the transport tabs 202a to 206a is positioned opposite the end face of the stack 36 already in the cassette 12a. Furthermore, pressure elements 242 to 248 are provided, which emerge from the areas between the transport belts 202 to 206 via a pull magnet 247 and which press the banknote 38 positioned opposite the end face of the stack 36 already in the cassette 12a against the end face of the stack 36, so that the supplied banknote 38 forms the new end face of the stack 36.

The lower area of a fed banknote 38 is additionally pressed against the banknote stack 36 by the impellers 232 to 240. In Figure 14 Individual elements of the cassette 12b, such as the transport belts 70a, 70b and transport rollers 249a to 249d, are also shown. The stripping elements 52a, 52b and those already in connection with are also included Figure 13 and the embodiment of the invention explained retaining elements 190a to 190f are shown in their rest position. This in Figure 14 The separating and stacking module 200 shown also has a magnetic coupling 242, via which the main drive shaft 42 with the drive wheels 44 can be optionally driven.

In Figure 15 is a simplified side view of the separating and stacking module 200 Figure 14 shown, where the feeding and separating elements are shown in a first position for feeding a banknote 38. A lower impeller 232 engages in the transport tab 202a after the conveyor belt 202 has been moved into a basic feed position in the opposite direction to the arrow P50. The impeller 232 has two protruding rigid blades. By engaging a wing of the impeller 232 in the transport tab 202a, it is opened further, so that a fed banknote 38 is guided into the area between the endless rotating conveyor belt 202 and the transport tab 202a provided on the outer peripheral surface. Furthermore, the separating and stacking module 200 includes a stepper motor 250 as a drive unit, which drives the drive shaft 53 to drive the impellers 232 via a belt drive 251 and the magnetic clutch 242. Furthermore, the cassette 12b shown in connection with the embodiment, in contrast to the cassette 12a of the embodiment according to the invention, does not have impellers arranged in the cassette 12a, but rather the already mentioned transport rollers 249a to 249d with a profiled peripheral surface. The profile of the transport rollers 249a to 249d has transverse ribs, through which a positive connection is created with the banknotes whose lower edge is in contact with the wheels 249a to 249d. This allows the banknotes to be transported safely towards the stack 36 or into the cassette 12b. The pressure element 242 is in Figure 15 simplified shown as a pivoting lever. Both the pivoting levers 242 to 248 serving as pressure elements and the profiled transport rollers 249a to 249d can also be used in the embodiment of the invention, in the same way those in the cassette 12a arranged impellers of the embodiment according to the invention as well as that in Figure 8 The pressure element shown and described in this context can be used in the embodiment not part of the invention.

In Figure 16 is the side view of the separating and stacking module 200 Figure 15 shown, the feeding and separating elements being shown in a second position when feeding a banknote 38. During the further circulation P50 of the endless conveyor belt 202, the banknote 38, which is arranged in areas in the transport tabs 202a to 206a, has been pulled out of these transport tabs 202a to 206a, the banknote 38 and the entire stack 36 being pressed away from the conveyor belt 202 with the aid of the pressure elements 242 to 248 have been. While the stack of banknotes 36 is pushed away from the conveyor belt 202, the endless conveyor belt 202 is driven against the direction of the arrow P50, with the lower impeller 232 continuing to be driven and rotated in parallel. A wing of the impeller 232 presses the lower area of the banknote 38 against the stack of banknotes 36.

In Figure 17 is the side view of the separating and stacking module 200 according to the Figures 15 and 16 shown, the feeding and separating elements being shown in a third position when feeding the banknote 38. In this position it can be seen that a wing of the lower impeller 232 simultaneously encompasses the rear edge of the banknote 38 being fed and also engages in the transport tab 202a.

In Figure 18 is the side view of the separating and stacking module according to the Figures 15 to 17 shown, the feeding and separating elements being shown in a fourth position, in which the lower region of the fed banknote 38 has been moved towards the stack with the aid of the lower impeller 232 and at the same time the transport tab 202a has been opened to feed another banknote.

In Figure 19 is a simplified side view of a separating and stacking module 200 according to the Figures 14 to 18 alternative separating and stacking module 252 for stacking and separating banknotes. The feeding and separating elements are shown in a first position when feeding a banknote. The separation and stacking module 252 differs from the separation and stacking module 200 according to the Figures 14 to 18 through the design of the lower impeller 232, the two blades of the lower impeller 232 in the separating and stacking modules 200, 252 each having an angular distance of 141° and 219°. In the separating and stacking module 200, the impeller 232 is rotated in such a way that when a banknote 38 is fed, the vanes are arranged in such a way that they face the banknote 38 with their smaller angular distance of 141°. In the separating and stacking module 252, the lower impeller 232 is rotated in such a way that the blades of the impeller 232 face the fed banknote 38 with their large angular distance of 219°. In Figure 19 the transport tab 202a is in in the same way as in connection with Figure 15 opened for a banknote 38 to be fed.

In Figure 20 is the side view of the separating and stacking module 252 Figure 19 shown, the feeding and separating elements being shown in a second position when feeding the banknote 38. At the same time as the conveyor belt 202 is driven, the lower impeller is rotated in the opposite direction to P50, so that the in Figure 16 Wings of the impeller 232 arranged at the bottom engage around the rear edge of the banknote 38 being fed and at the same time engage in the transport tab 202a, as shown in Figure 21 is shown. As a result, the wing presses the lower area of the supplied banknote 38 towards the stack 36 and at the same time opens the transport tab 202a, as shown in Figure 22 is shown.

In Figure 23 is one in the vault 10 after Figure 1 arranged banknote cassette 12b with a separating and stacking module 200 according to the embodiment not part of the invention for feeding and removing banknotes. Furthermore, a section of the transport path 18 and a pair of transport rollers 260 with a drive roller 262 and a pressure roller 264 are shown. With the help of the pair of transport rollers 260, a transport path for banknotes is formed between the separating and stacking module 200 and the transport path 18. The transport elements of the transport path 18 and switches arranged in this transport path are in Figure 23 not shown. The isolation and 23, stacking module 200 is already in the basic stacking position, in which a banknote to be fed to the cassette 12b can be transported into the gap between the opened transport tab 202a and the endless conveyor belt 202 with the help of the drive wheel 44. The displacement carriage 82 arranged in the cassette 12b is in Figure 23 not shown.

The conveyor belts 202 to 206 with the transport tabs 202a to 206a are also referred to as scale belts, since the transport tabs 202a to 206a lie like scales on the respective conveyor belt 202 to 206. Preferably, both the endless conveyor belts 202 to 206 and the transport tabs 202a to 206a are made of a polyester film with a uniform thickness in the range of 0.1 to 0.75 mm, preferably in the range of 0.2 to 0.35 mm. A strength of 0.25 has proven to be advantageous. The separating and stacking module 200 according to the embodiment not part of the invention is particularly suitable for a vertical cassette arrangement, i.e. H. when the cassette is arranged in such a way that the end face of the stack 36 is arranged in a horizontal plane, preferably at the top of the stack.

A particular advantage of the separating and stacking module 200, 252 with the conveyor belts 202 to 206 is that a banknote 38 to be fed is protected in the transport tabs 202a to 206a when it is transported in front of the end face of the stack 36. Banknote 38 is in the front Note section is covered by the relatively wide transport tabs 202a to 206a and has no direct contact with the end face of the stack 36 in the area of the transport tabs 202a to 206a. As a result, the fed banknote 38 cannot get caught in protruding areas of used banknotes. Compared to other embodiments, lower demands are placed on the rigidity of the banknotes to be fed against buckling. Thanks to the conveyor belts 202 to 206, a flat and low-mass design of the feed elements is possible. Furthermore, linear guidance of the banknote is achieved by the conveyor belt 202, which is deflected via two deflection rollers with the transport tabs 202a to 206a. The endless conveyor belt 202 with the at least one transport tab 202a, preferably with two transport tabs each, can be made from two punched films which are welded together at at least two connection points, preferably by a welded connection each, to form the endless conveyor belt 202 with transport tab 202a. An ultrasonic welding process is particularly suitable as a welding process. A banknote is withdrawn from the cassette 12b in the embodiments according to Figures 14 to 23 in the same way as for the embodiment in connection with Figures 2 to 13 described.

In Figure 24 is a top view of a stacking and separating wheel shaft 270 of a separating and stacking module of a further embodiment not belonging to the invention with a total of three stacking and separating wheels 272 to 276 arranged on this shaft are shown. The stacking wheel shaft 270 is driven by an electric motor, the shaft 270 being driven via a toothed belt pulley 278 which is non-rotatably connected to the shaft 270. Furthermore, a total of three toothed belt pulleys 280 to 284 are non-rotatably connected to the stacking and separating wheel shaft 270, via which cam disks which are freely rotatably mounted on a shaft arranged parallel to the stacking and separating shaft 270 can be driven with the help of toothed belts 286 to 290.

In addition to the separating and stacking wheels 272 to 276, two additional stacking wheels 292, 294 are provided, which have no take-off elements and therefore no separating function. The separating and stacking wheels 272 to 276 each have two extraction elements 272a, 272b, 274a, 274b, 276a, 276b that can be moved out of the peripheral surface of the separating and stacking wheels 272 to 276. The outer sides of these withdrawal elements 272a to 276b are each profiled by transverse grooves and have a relatively high coefficient of friction, so that banknotes can be moved or withdrawn with the help of the withdrawal elements 272a to 276b even with a relatively low pressure force. For example, at least the surface of the trigger elements 272a to 276b is made of a rubber material.

Furthermore, the stacking and separating wheel shaft 270 has control levers 296, 298, the end of which is remote from the stacking and separating wheel shaft 270 for controlling the movement the retaining or pressure elements 190_serves. Furthermore, clamping elements arranged in the stacking and separating wheels 272 to 276 can be controlled via the control levers 296, 298 via a cam disk arranged on the already mentioned parallel shaft and/or via cam disks arranged in the stacking and separating wheels. The belt drives 280 to 290 for driving the cam disks, of which in Figure 24 The pulleys 280 to 284 arranged on the stacking and separating wheel shaft 270 and the toothed belts 286 to 290 are shown have a ratio to the pulleys coupled to the cam disks. In the present embodiment, the separating and stacking wheels 272 to 270 each have two stacking chambers, with a gear ratio of 1 to 2 being provided, so that the cam disks have twice the number of revolutions as the stacking and separating wheel shaft 270.

Figure 25 shows a perspective view of the separating and stacking wheel shaft 270 Figure 24 . In the presentation according to Figure 25 A chamber 272c to 276c is shown for accommodating an area of a banknote to be fed from the separating and stacking wheels 272 to 276 and the stacking wheels 292 and 294. The visible chamber of the separating and stacking wheel 272 is designated by reference number 272c, the visible chamber of the separating and stacking wheel 274 is designated by reference number 274c and the chamber of the separating and stacking wheel 276 is designated by reference number 274c. The visible chamber of the stacking wheel 292 is designated by reference numeral 292c and the visible chamber of the stacking wheel 294 is designated by reference numeral 294c.

In Figure 26 is a side view of the stacking and separating wheel shaft 270 according to the Figures 24 and 25 shown, in which the second chamber 292d of the stacking wheel 292 is also visible.

The Figure 27 shows the side view of the separating and stacking wheel 272 with the chambers 272c and 272d for receiving banknotes. Furthermore, the axis of rotation 300 of the cam disk 302, which runs parallel to the separating and stacking wheel shaft 270, is shown. The cam disk 302 is scanned via the lever 296, and depending on the course of the cam disk 302, at least one of the two trigger elements 272a, 272b can be moved out of the peripheral surface of the separating and stacking wheel 270 via the lever 296 in order to move the cam disk 302 in the cassette 12c on one Front side of the stack 36 arranged banknote to contact.

In Figure 27 A starting position for separating (basic separating position) of the banknotes present in the cassette 12c and arranged in a stack 36 is shown. An impeller 304 with a vane 306 is rotated in a separating mode so that the vane 306 does not protrude into the transport path for transporting away the banknotes pushed down from the end face of the stack 36 with the aid of the withdrawal elements 272a, 272b. Through the rotation of the Separating and stacking wheel 272, the banknote arranged on one end face of the stack 36 is pushed down into a transport gap between the drive wheel 44 and the pressure roller 50. Furthermore, the in Figure 27 Arrangement shown on stripping rollers 52, which are not rotated when a banknote is being transported away or which are alternatively rotated against the transport direction of the banknote during transport, so that in the event of a double withdrawal, the second banknote behind the banknote that is contacted by the stripping element 272a, 272b with the banknote shifted downwards is not in the Transport gap between the drive wheel 44 and the pressure roller 50 comes. The arrangement also has a sensor arrangement for detecting the front edge of a banknote 38 to be removed. In addition, the sensor arrangement can detect the trailing edge of the banknote 38 being transported away. The sensor arrangement includes in particular a light source 308 and a receiver 310, which together with an evaluation unit (not shown) form a light barrier sensor arrangement. When feeding banknotes, the impeller 304 is rotated in such a way that the wing 304 protrudes into the transport path for discharging banknotes, so that in particular the banknotes being fed cannot get into this transport gap.

In Figure 28 is the arrangement according to Figure 27 with the trigger element 272a pivoted outwards, the trigger element 272a in the moved out state contacting the surface of the banknote 38 arranged on the end face of the stack 36 and with a further rotational movement of the separating and stacking wheel 272, the banknote 38 moves downward into the transport gap between the Wiping element 52 and the drive wheel 44 or between the pressure roller 50 and the drive wheel 44. As an alternative to the belt drive of the cam 302 shown, the cam 304 can also be driven via an electric motor, preferably a stepper motor, possibly together with other cams.

In Figure 29 is the arrangement according to the Figures 27 and 28 shown, the feeding and separating elements being shown in a position in which the banknote 38 arranged on the front side of the stack 36 has already been pushed into the transport gap between the drive wheel 44 and the pressure roller 50. As a result, the banknote 38 interrupts the light beam between the light source 308 and the receiver 310, so that the light barrier arrangement detects the removed banknote 38.

In Figure 30 is the arrangement according to the Figures 24 to 29 shown, the feeding and separating elements being shown in an operating mode for feeding banknotes into the cassette 12c. There is already a stack of banknotes 36 in the cassette 12c. The impeller 304 with the wing 306 is rotated in such a way that the banknotes of the stack 36 as well as further banknotes 38 that are supplied cannot reach the area between the drive wheel 44 and the stripping element 52 or the drive wheel 44 and the pressure roller 50. A banknote 38 to be fed is fed to the arrangement from the transport path 18 via transport elements 312, 314, 316 and a switch 318, the switch 318 continuing to serve as a guide element. The fed banknote 38 is included Sections of its front area are transported into the chamber 272c. The separating and stacking wheel 272 is in Figure 30 shown in a starting position for feeding banknotes into the cassette 12c.

In Figure 31 is the arrangement according to the Figures 27 to 30 shown, the feeding and separating elements being shown in a second feeding position. A clamping element, not shown, controlled by a further cam and a further lever 320a presses the banknote 38 in the chamber 272c from the inside against the outside of the chamber, so that the banknote 38 is clamped in the chamber 272c. The process is controlled in such a way that rotation of the separating and stacking wheel 272 is started at the latest when the front edge of the banknote 38 being fed has reached the chamber bottom or the front side of the chamber 272c, which forms a stop for the banknote 38 in the transport direction. After the front edge of the banknote 38 has reached the front side of the chamber 272c or immediately afterwards, the banknote 38 is clamped in the chamber 272c controlled by the cam and controlled by the lever 320a. The lever 320a is pressed against the outside of the chamber 272c against the spring force of a spring 322a.

In Figure 32 is the arrangement according to the Figures 27 to 31 shown, the feeding and separating elements being shown in a third feeding position, in which the separating and stacking wheel 272 is opposite that in Figure 31 shown second feed position is rotated further. This In the feed position, the area of the banknote 38 clamped in the chamber 272c is still arranged in the chamber 272c. In the in Figure 32 In the position shown, the clamping lever 322a is released via the cam, so that the area of the banknote 238 is still in the chamber 272c but is no longer clamped. Furthermore, the rear area of the banknote 38 is no longer in engagement with the transport elements 312 to 318, as a result of which the banknote 38 is lifted off the lateral surface of the separating and stacking wheel 272 due to its rigidity and thereby stands up towards the end face of the stack 36. During a further rotational movement of the separating and stacking wheel 272, the front edge of the fed banknote 38 abuts against several stripping elements 324 arranged between the drive wheels 44, through which the movement of the banknote 38 is stopped. At the same time, the separating and stacking wheel 272 continues to rotate, so that the front area of the banknote 38 is no longer arranged in the chamber 272c when the separating and stacking wheel 272 rotates further. As a result, the fed banknote 38 is no longer in engagement with the separating and stacking wheel 272. Due to the rigidity of the fed banknote 38, it stands up so that it is arranged directly in front of the end face of the stack 36 already in the cassette 12c and the new one Forms the front side of the stack.

In Figure 33 is a side view of the stacking and separating wheel 272 according to the further embodiment not part of the invention shown without an inner cam. The cam, not shown, controls or guides the movement the clamping levers 320a, 320b, with the springs 322a, 322b pressing the lever ends against the cam. In Figure 34 is the stacking and separating wheel 272 Figure 33 in another side view and in Figure 35 shown in a perspective view. Figure 36 shows another side view of the stacking and separating wheel 272, the one in Figure 33 The side shown on the opposite side of the stacking and separating wheel 272 is shown without a second cam. With the help of this second cam, the movement of the stripping elements 272a, 272b out of the peripheral surface of the stacking and separating wheel 272 is controlled via a lever assigned to the respective stripping element 272a, 272b. Springs are provided which press the end of the lever that is not connected to the stripping elements against the cam. The stripping elements are moved out of the peripheral surface of the stacking and separating wheel 272 with the help of the spring force of these springs depending on the course of the cam.

In Figure 37 a side view of the cassette 12c is shown together with a note withdrawal flap 326 similar to the note withdrawal flap 68, which has cutouts adapted to the stacking and separating wheels 272 to 278 and the separating wheels compared to the note withdrawal flap 68. Furthermore, further transport elements for providing a transport path 18 are shown. In contrast to the other embodiments described, two switches must be arranged in the transport path 18 for the separating and stacking module according to this embodiment, which is not part of the invention, since the Banknotes 38 to be fed into the separating and stacking module are fed to the stacking and separating wheels 272 to 276 in the upper area and removed banknotes are removed by the stacking and separating wheels 272 to 276 in the lower area. The note withdrawal flap 326 and the banknote stack 36 are in Figure 37 shown in its stacking and separating position and in a rest position, the note withdrawal flap in the rest position being designated by the reference number 326 'and the stack of banknotes by the reference number 36'.

In Figure 38 is a side view of a separating and stacking module 350 according to a further embodiment not part of the invention, which is an alternative to the separating and stacking modules 30, 200, 252, 270 of the other exemplary embodiments as a separating and stacking module 14a to 14d Figure 1 can be used. The separating and stacking module 350 engages the cassette 12a in the same way as in connection with the exemplary embodiment of the invention according to FIGS Figures 2 to 13 explained. Furthermore, the function and structure of the impellers 54, the note retraction flap 68, the drive wheel 44, and the scraper wheel 52 correspond to the exemplary embodiment of the invention.

In contrast to the exemplary embodiment of the invention according to Figures 3 to 13 In this embodiment, which is not part of the invention, is a lower impeller 232 according to the second exemplary embodiment the invention according to the Figures 15 to 23 intended. Furthermore, instead of the pressure device 45 a pressure device 352 is provided. The pressure device 352 includes a pull magnet drive 354, which is coupled to a pressure plunger 358 via a lever 356. The movement of the pull magnet drive 354 is redirected about a stationary axis of rotation 360. Furthermore, the movement of the plunger 358 is preferably limited or guided via further guide elements, not shown. The axis of rotation 360 is preferably formed via a housing frame 362 arranged on the side of the separating and stacking module 350, which protrudes through a complementary opening provided in the lever 356 and thereby forms a deflection axis or axis of rotation 360.

In the in Figure 38 In the feed position shown, the banknote 38 is transported into the feed area 46, the impeller 54 already being moved out of its basic stacking position in order to provide the fed banknote 38 with sufficient space at the top and not to hinder the movement of the banknote 38 when being fed into the feed area 46 , in particular not to form a height stop.

At the in Figure 39 In the feed position shown, the upper impeller 54 has been rotated further. In the in Figure 39 In the position of the impeller 54 shown, the already explained flap rotation of the impeller 54 takes place. Furthermore, the lower impeller 232 has been rotated. Furthermore, the pull magnet drive 354 has been activated, so that the pressure plunger 358 contacts the supplied banknote 38 in its lower half and presses it towards the end face of the stack 36.

In Figure 40 A further subsequent feeding position is shown when feeding the banknote 38 into the cassette 12a. The lower impeller 232 and the upper impeller 54 have been rotated further, as a result of which the second wing 58 contacts the fed banknote 38 in its upper half more with the outside of the curved region of the wing 58 and the banknote 38 through the further movement of the impeller 54 until it reaches its basic stacking position, it moves further in the direction of the stack 36 and presses it against the end face of the stack 36. In the same way, the lower impeller 232 is rotated further and contacts the fed banknote 38 in its lower half, preferably on its lower edge, and presses the lower region of the fed banknote 38 against the end face of the stack 36 already present in the cassette 12a. Furthermore, in Figure 40 shown that a further banknote 40 is already transported into the feed area 46 in this feed position. By pressing the banknote 38 against the front side of the stack 36, the banknote 38 subsequently forms the front side of the stack 36. The further process when feeding the banknote 40 corresponds to the described process for feeding the banknote 38.

In Figure 41 is the separating and stacking module 350 according to the Figures 38 to 40 shown, the separating and stacking elements being shown in a separating position. The upper impeller 54 is in the basic stacking position already described in connection with the exemplary embodiment according to the invention been rotated. Furthermore, the stack 36 located in the cassette 12a has been moved towards the withdrawal wheel 32, so that the front of the banknote 38 forming the end face of the stack 36 is pressed against the lateral surface of the withdrawal wheel 32. By rotating the withdrawal wheel 32, the banknote 38 is pushed down into the gap between the drive wheel 44 and the stripper roller 52 and between the drive wheel 44 and the pressure roller 50. The banknote 38 separated in this way is transported further to the transport path 18 by a corresponding rotational movement of the drive wheel 44. The note retraction flap 68 is in the Figures 38 to 41 The views shown are shown in an open position and can be operated in the same manner as in connection with the exemplary embodiments in connection with Figures 2 to 37 described.
