Description

[Technical field]

[0001] The present invention relates to a method for forming a stack of sheets, in particular a stack of valuable documents, by means of a sheet processing device, in particular a processing device for documents of value, and to a sheet processing device, in particular a processing device for documents of value, adapted to carry out said method. [Background technology]

[0002] Cash / valuables transport companies or central banks use valuable document processing equipment to handle a variety of valuable documents, such as identifying, sorting, counting and stacking. The stacks of valuable documents formed in this process are packed for storage and / or transportation purposes into valuable document containers typically provided for this purpose.

[0003] In the valuable document handling machine, valuable documents are separated from the stack of valuable documents and conveyed past sensors in a transport line. Each valuable document is verified by the sensor and, depending on the verification, is sent to specific target locations in the machine, such as dispensing compartments. The verified valuable documents are sent to stacker wheels in the machine. The stacker wheels rotate such that each valuable document is individually packed into its compartments. An ejector is used to eject the valuable documents from their compartments on the stacker wheel, thus forming a stack of valuable documents that is dispensed from the valuable document handling machine.

[0004] It is also known practice that a stack of valuable documents dispensed in a distribution area of ​​the valuable document handling device is removed from the distribution area by a gripper and placed in a valuable document container positioned in the immediate vicinity of the gripper. The disadvantage of this is that the stacking performed by the stacker wheel must be stopped for a long time in order to enable the gripper to remove the stack of valuable documents. This is because the stacker wheel can only resume stacking a further stack of valuable documents when a previous stack of valuable documents has been removed from the distribution area of ​​the valuable document handling device by the gripper. The long interruption of stacking reduces the throughput of valuable documents of the valuable document handling device.

[0005] Similarly, in the case of the formation of other sheet stacks which are not stacks of valuable documents, for example stacks of sheet-like electrode elements, it is also possible that the removal of a previous stack of electrode elements (which requires an interruption of the stacking) can cause a reduction in the throughput of the apparatus which processes, i.e. stacks, the sheet-like electrode elements. Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE DISCLOSURE An object of the present invention is to increase the sheet throughput, and in particular the throughput of valuable documents, of a sheet processing device, and in particular a processing device for valuable documents. [Means for solving the problem]

[0007] This object is achieved by a method and a sheet processing device, in particular a processing device for valuable documents, according to the independent claims.

[0008] According to a first aspect of the present disclosure, a method for forming a stack of sheets, in particular a stack of valuable documents, in a distribution area of ​​a sheet processing device, in particular a processing device for valuable documents, comprises: a) stacking sheets / valuable documents by stacker wheels of a sheet handling device / valuable document handling device onto a stack of sheets / valuable documents positioned on a lift platform; b) introducing a stacking platform into the dispensing area of ​​the sheet handling device / valuable document handling device such that the stacking platform is located directly below the stacker wheels and above the top sheet / valuable document of the stack of sheets / valuable documents formed on the (possibly lowered) lifting platform; c) stacking further sheets / valuable documents by the stacker wheel onto a stacking platform located beneath the stacker wheel to form a further stack of sheets / valuable documents on the stacking platform; d) introducing a gripping device into the dispensing area of ​​the sheet handling device / valuable document handling device and lifting the stack of sheets / valuable documents formed on the lift platform by the gripping device; e) removing the stack of sheets / valuable documents formed on the lift platform from the dispensing area of ​​the sheet handling device / valuable document handling device by means of a gripping device; After removal of the sheet stack / valuable document stack, f) raising the lifting platform to the deposition platform; g) transferring the further stack of sheets / stack of valuable documents formed on the depositing platform onto the lifting platform and moving the depositing platform away from the dispensing area; Includes.

[0009] According to a second aspect of the present disclosure, a sheet handling device, particularly a valuable document handling device, is made to form a stack of sheets, particularly a stack of valuable documents, in a distribution area of ​​the sheet handling device / valuable document handling device, the sheet handling device / valuable document handling device having a stacker wheel, a lifting platform, a stacking platform, a control device, and a gripping device, where the sheet handling device / valuable document handling device is made to stack sheets / valuable documents processed by the sheet handling device / valuable document handling device onto the lifting platform and the stack of sheets / valuable documents located directly under the stacker wheel in the distribution area of ​​the sheet handling device / valuable document handling device. The control device is preferably made such that, during the time when stacking by the stacker wheels is interrupted, a stacking platform is introduced into the distribution area of ​​the sheet handling device / valuable document handling device, so that the stacking platform is located in a position directly below the stacker wheels and above the top sheet / valuable document of the stack of sheets / valuable documents formed on the (possibly lowered) lift platform. Furthermore, the sheet handling device / valuable document handling device is made such that, after the introduction of the stacking platform into the distribution area, further sheets / valuable documents processed by the sheet handling device / valuable document handling device are stacked on the stacking platform located directly below the stacker wheels to form a further stack of sheets / valuable documents on the stacking platform. Further, the control device is made such that the gripping device is introduced into the distribution area of ​​the sheet processing device / valuable document processing device so that the sheet stack / valuable document stack is lifted by the gripping device, and the gripping device removes the sheet stack / valuable document stack formed on the lifting platform from the distribution area of ​​the sheet processing device / valuable document processing device, and after removal of the sheet stack / valuable document stack formed on the lifting platform, the lifting platform is raised to the stacking platform, a further sheet stack / valuable document stack formed on the stacking platform is transferred onto the lifting platform, and the stacking platform is moved away from the distribution area.

[0010] Depending on preference, a sheet handling device / valuable document handling device and a control device are made to carry out the above steps for a plurality of stacks of sheets / valuable documents in sequence, the control device causing corresponding adjustment devices, e.g. motors or actuators, to carry out the respective movements of the stacking platform and the lifting platform and the gripping device.

[0011] Aspects of the present disclosure are preferably based on an approach whereby the further stack of sheets / stack of valuable documents is temporarily stored on a deposition platform until the lift platform is available to accept the further stack of sheets / stack of valuable documents, i.e. until the gripping device has removed the (previous) stack of sheets / stack of valuable documents from the lift platform and the lift platform is ready to transfer the further stack of sheets / stack of valuable documents.

[0012] This approach has the advantage that the stacker wheel can already start stacking a further stack of sheets / valuable documents while, or even before, the previous stack of sheets / valuable documents is being removed from the distribution area of ​​the sheet handling device / valuable document handling device, in particular by the gripper. The effect of the temporary storage of the further stack of sheets / valuable documents on the stacking platform is that there is no interruption or only a short interruption in stacking by the stacker wheel is required before the stacker wheel starts stacking the further stack of sheets / valuable documents. This increases the sheet throughput / valuable document throughput of the stacker wheel or the sheet handling device / valuable document handling device.

[0013] The stacking platform is made to be able to be moved away (transversely to the stacking direction of the sheet stack / valuable document stack, e.g. backwards) out of the distribution area. The (lateral) movement of the stacking platform out of the distribution area in step g) is performed in order to be able to re-stack the sheets / valuable documents from the stacking wheels on the lifting platform. The stacking platform therefore only needs to be able to perform a one-dimensional lateral movement and does not - like the lifting platform - need to be movable in the stacking direction.

[0014] The stacking platform can preferably only be displaced perpendicular to the stacking direction and in the opposite direction, for example being introduced from the rear into the distribution area and moved away backwards to leave the distribution area. The lifting platform needs to be displaceable only in the opposite direction along the stacking direction, but may not need to be displaceable perpendicular to the stacking direction. This has the advantage that both platforms require simple drives and little space is needed for their movements.

[0015] The lifting platform is preferably constructed such that the stacker wheels are lowered downwards while depositing sheets / valuable documents onto a stack of sheets / valuable documents formed on the lifting platform.

[0016] After step g), steps a) to g) can be repeated, in particular for a further stack of sheets / stack of valuable documents and, if appropriate, for a subsequent stack of sheets / stack of valuable documents, which during the repetition takes the place of the stack of sheets mentioned in step a). While steps a) to g) are repeated for the further stack of sheets / stack of valuable documents, stacking is achieved as in step a), i.e. the further stack of sheets / stack of valuable documents has been transferred from the deposition platform onto the lifting platform. As a result of the repetition, the sheets / valuable documents are stacked on the further stack of sheets / stack of valuable documents and, if appropriate, on the subsequent stack of sheets / stack of valuable documents, which are removed from the lifting platform by the gripping device and leave the dispensing area. The repetition allows for a continuous dispensing process of the sheet handling devices / valuable document handling devices and therefore a higher throughput of the sheet handling devices / valuable document handling devices during processing of sheets / valuable documents.

[0017] The stack of sheets / stack of valuable documents positioned on the lifting platform in step a) could be formed by stacking the sheets / stack of valuable documents on the lifting platform by the stacker wheels or by transferring the stack of sheets / stack of valuable documents from a deposition platform onto the lifting platform as in step g). In step a), the lifting platform can be lowered down while the stacker wheels are depositing the sheets / stack of valuable documents onto the stack of sheets / stack of valuable documents.

[0018] The introduction of the stacking platform into the dispensing area of ​​the sheet processing device / valuable document processing device as in step b) can be controlled, for example, by a trigger signal received by the control device once the sheet stack / valuable document stack reaches a certain number of sheets / valuable documents.

[0019] Although the stacker wheels may pause the stacking operation in order to introduce the stacking platform and / or to transfer the stack of sheets / valuable documents from the stacking platform onto the lifting platform, the sheet handling device / valuable document handling device preferably continues to process sheets / valuable documents during the pause in stacking by the stacker wheels, and the sheets / valuable documents processed during the pause in stacking are transported to another target location of the sheet handling device / valuable document handling device, for example into another stacker or into another distribution area or to a shredder of the sheet handling device / valuable document handling device. The associated pause in stacking is therefore, so to speak, only integrated individually into the associated stacker wheel.

[0020] For example, the stacking of sheets / valuable documents by the stacker wheels onto the stack of sheets / valuable documents formed on the lifting platform is interrupted before the introduction of the stacking platform, i.e. before the introduction of the stacking platform as in step b), step b0) can be performed: b0) Interruption of stacking by stacker wheels.

[0021] As in step b), the introduction of the depositing platform is preferably performed while the stacking by the stacker wheels is interrupted, which has the advantage that collisions between the depositing platform and sheets / valuable documents which are currently to be deposited and which are falling onto the stack of sheets / valuable documents are completely eliminated.

[0022] An interruption of stacking by a stacker wheel or a pause in stacking by a stacker wheel can be achieved, for example, by interrupting the feeding of sheets / valuable documents to the stacker wheel while the stacker wheel is still rotating. This can be achieved by stopping a separator of the sheet handling device / valuable document handling device or the sheets / valuable documents being processed by the sheet handling device / valuable document handling device during the interruption or pause in stacking by the associated stacker wheel are transported to another target location of the sheet handling device / valuable document handling device (see, for example, above).

[0023] After the stacking platform is introduced, the stacker wheel can again begin stacking further sheets / valuable documents onto the stacking platform located directly below the stacker wheel to form a further stack of sheets / valuable documents on the stacking platform.

[0024] It is preferred if the lifting platform is lowered downwards together with the stack of sheets / stack of valuable documents during or after the stacking operation in order to introduce the stacking platform and / or provide space for the accumulating sheets / valuable documents. Depending on preference, the lifting platform is lowered downwards (step by step or continuously) while the stacker wheels are depositing sheets / valuable documents onto the stack of sheets / stack of valuable documents, for example based on a signal from a sensor positioned under the stacker wheels and detecting the sheets / valuable documents. The lowering is effected here in such a way that the upper side of the stack remains at approximately the same height, in particular at a suitable distance from the stacker wheels, which distance allows for a precise stacking operation. This downward readjustment of the lifting platform has the advantage that the sheets / valuable documents can be deposited more precisely together with the growing stack of sheets / stack of valuable documents.

[0025] As in step b0), the stacking is interrupted but the lifting platform continues to be lowered downwards to provide more space for introducing a depositing platform onto the stack of sheets / stack of valuable documents formed on the lifting platform. The lifting platform continues to be lowered downwards (during / after the interruption of stacking as in step b0)) until for example an introduction condition is met. The introduction condition is for example that the lifting platform has reached a position or that the upper end of the stack has reached an end position, for example directly below a light barrier. Once the introduction condition is met, for example the end of the stack has reached an end position during the lowering movement, as in step b), the depositing platform is introduced into the dispensing area of ​​the sheet handling device / precious document handling device, and as in step c), further sheets / precious documents are stacked by the stacker wheel onto the depositing platform arranged directly below the stacker wheel to form a further stack of sheets / stack of valuable documents on the depositing platform. The lowering of the lifting platform together with the sheet stack / valuable document stack can, if appropriate, be continued after the introduction of the depositing platform, as in step b), however, it is also possible to omit the lowering of the lifting platform in order to introduce the depositing platform when there is a correspondingly large distance between the stacker wheels and the upper side of the final sheet stack / valuable document stack.

[0026] If there has been an interruption in the stacking, as in step b0), then the stacking, as in step c), comprises resuming the stacking of further sheets / valuable documents by the stacker wheels onto a stacking platform located directly below the stacker wheels to form a further stack of sheets / valuable documents on the stacking platform. If there has been no interruption in the stacking, as in step b0), then the stacking, as in step c), comprises continuing the stacking of further sheets / valuable documents by the stacker wheels onto a stacking platform located directly below the stacker wheels to form a further stack of sheets / valuable documents on the stacking platform.

[0027] The deposition platform may have a planar, e.g., plate-like, or rake-like shape. The lifting platform may also have a planar, e.g., plate-like, or rake-like shape.

[0028] The rear boundary of the distribution area preferably has one or more openings that complement the deposition platform, so that the deposition platform can penetrate into the openings. For example, the deposition platform has a rake-like shape and the rear boundary of the distribution area has a number of openings that complement the fingers of the rake-like deposition platform. Alternatively, the deposition platform has a planar, e.g. plate-like, shape and the complementary openings in the back wall have a corresponding slot-like shape.

[0029] In particular, the deposition platform and the lifting platform have a complementary rake-like shape. They each have two or more fingers forming a rake. Complementary or complementary here means that the fingers of the lifting platform are in the gaps relative to the fingers of the deposition platform, i.e. the fingers of the lifting platform can fit into the gaps between the fingers of the deposition platform and vice versa. When the deposition platform and the lifting platform have a complementary rake-like shape, interlocking between the deposition platform and the lifting platform is possible.

[0030] When the depositing platform has a rake-like shape, it is preferred if the rear boundary of the distribution area has a number of openings, which complement the fingers of the rake-like depositing platform. For example, the back wall of the distribution area can have openings, or the rear boundary of the distribution area can have lattice-like bars, between which there are openings that complement the fingers of the rake-like depositing platform. This allows a particularly easy transfer of a further stack of sheets / stack of valuable documents from the depositing platform onto the lifting platform by using the rear boundary to dislodge the stack when the depositing platform, or its fingers, are moved laterally out of the distribution area or through the rear boundary.

[0031] As in step f), raising the lifting platform is stopped when the lifting platform is positioned on / above the deposition platform, e.g. when the lifting platform is positioned directly on the underside of the deposition platform, if both have complementary rake-like shapes, when the lifting platform penetrates into or through the complementary deposition platform (they interlock with each other). After the lifting platform is raised up to the deposition platform, as in step f), the lifting platform can be positioned on / above the deposition platform.

[0032] As in step g), when the further sheet stack / stack of valuable documents formed on the deposition platform is being transferred onto a lifting platform positioned on the deposition platform, the lifting platform can, for example, be directly below the deposition platform or engage with it at approximately the same height.

[0033] To transfer the further stack of sheets / stack of valuable documents from the depositing platform onto the lifting platform, as in step g), in particular two transfer variants are possible:

[0034] First movement variant In a first transfer variant, in step g), the further stack of sheets / stack of valuable documents is transferred onto the lifting platform by a movement (directed transversely to the stacking direction) away from the deposition platform. In the process, the stack of sheets / stack of valuable documents positioned on the deposition platform is preferably dislodged at the rear boundary of the distribution area in order to transfer the further stack of sheets / stack of valuable documents onto the lifting platform. In particular, in the process, the transfer of the further stack of sheets / stack of valuable documents from the deposition platform onto the lifting platform is achieved by a (transverse) movement away from the deposition platform, for example through the rear boundary of the distribution area, out of the distribution area.

[0035] The rear boundary of the distribution area preferably has one or more openings, which are complementary to the deposition platform. Complementary or complementary means here that the openings are shaped in such a way that the deposition platform can penetrate into the openings at the rear boundary. The rear boundary of the distribution area can be in the form of a back wall, which is provided with one or more openings or has a grid of bars with openings between them.

[0036] For example, in the first movement variant, the lifting platform is raised up to the depositing platform and the lifting movement is stopped as soon as the lifting platform rests directly against the underside of the depositing platform or - if they each have a mutually complementary rake-like shape - when the lifting platform engages with the depositing platform and is at least approximately at the same height as the depositing platform. The depositing platform on which the further stack of sheets / stack of valuable documents is formed is therefore positioned in a position directly below the stacker wheels and moved away (laterally), e.g. backwards (laterally meaning with respect to the stacking direction, e.g. perpendicular to the stacking direction), so that the stack of sheets / stack of valuable documents formed on the depositing platform falls or is transferred by a movement away from the depositing platform onto the lifting platform (positioned below it or engaged at the same height).

[0037] However, the deposition platform in the first variant does not have to have a rake-like shape, but can have a planar, e.g. plate-like, shape, in the latter case allowing the complementary opening in the back wall to have, e.g. a slot-like shape. In the non-rake-like case, the lifting platform is moved directly onto the underside of the deposition platform, and the deposition platform and the lifting platform do not interlock.

[0038] Second Movement Variation In a second movement variant, the depositing platform and the lifting platform have a mutually complementary rake-like shape, and in step g) the further stack of sheets / stack of valuable documents is transferred from the depositing platform onto the lifting platform by an upward movement of the lifting platform along the stacking direction.

[0039] To transfer the further stack of sheets / stack of valuable documents, the lifting platform is moved from below to above through the complementary rake-like depositing platform to raise the further stack of sheets / stack of valuable documents from the depositing platform and thereby transfer it onto the lifting platform. In step g), the movement away from the depositing platform is effected at the same time that the further stack of sheets / stack of valuable documents is being transferred from the depositing platform onto the lifting platform or (just after) the further stack of sheets / stack of valuable documents has been transferred.

[0040] In a second variant of the transfer operation, the lifting platform and a complementary rake-like depositing platform are moved past each other so as to interlock with each other. The lifting platform is moved upwards so that its rake fingers enter / pass through complementary openings between the fingers of the lifting platform, so that the lifting platform takes on or removes the sheet stack / valuable document stack from the depositing platform. Immediately after this transfer operation, the depositing platform (hence separated from the sheet stack / valuable document stack) is moved away, for example laterally.

[0041] As in step c), the stacking of further sheets / valuable documents by the stacker wheels onto the further stack of sheets / stack of valuable documents can be continued while the stack of sheets / stack of valuable documents is being transferred onto the lifting platform (according to the first or second transfer variant). As an alternative, the transfer operation can incorporate pauses in the stacking by the stacker wheels. Depending on preference, a movement out of the dispensing area and away from the deposition platform is made while further sheets / valuable documents are being stacked by the stacker wheels onto the further stack of sheets / stack of valuable documents.

[0042] The gripper is designed to lift a stack of sheets / valuable documents formed on the lifting platform between two gripping elements of the gripper and to remove said stack from the dispensing area.

[0043] As in step d), before the introduction of the gripping device into the dispensing area, in step d0), the sheet stack / stack of valuable documents deposited on the lifting platform can be pre-compressed between the lifting platform and the stacking platform in the opposite stacking direction. For pre-compression, the sheet stack / stack of valuable documents deposited on the lifting platform is clamped and pressed together between the lifting platform and the stacking platform in the opposite stacking direction, for example until a predetermined distance is reached between the lifting platform and the stacking platform. Pre-compressing the sheet stack / stack of valuable documents reduces the height of the sheet stack / stack of valuable documents measured in the stacking direction. As a result of the pre-compression, the sheet stack / stack of valuable documents is given a higher stability and can therefore be removed more stably by the gripping device. The pre-compression of the sheet stack / valuable document stack may also continue until or while the sheet stack / valuable document stack reaches or is below a certain maximum height determined by the maximum opening width of the gripping device.

[0044] In order to pre-compress the sheet stack / stack of valuable documents formed on the lifting platform, the lifting platform together with the sheet stack / stack of valuable documents deposited thereon is raised in a direction towards the deposition platform so that the sheet stack / stack of valuable documents hits the deposition platform from directly below, and the raising of the lifting platform is continued after the sheet stack / stack of valuable documents hits the deposition platform to press, i.e. compress, the sheet stack / stack of valuable documents together between the lifting platform and the deposition platform in the opposite stacking direction.

[0045] In the case of pre-compressing the stack of sheets / stack of valuable documents formed on the lifting platform, when the stack of sheets / stack of valuable documents is removed by the gripping device as in step e), the stack of sheets / stack of valuable documents is released from the clamping fit formed between the lifting platform and the deposition platform.

[0046] When the gripping device is introduced into the dispensing area as in step d), the gripping device lifts the sheet stack / stack of valuable documents between two gripping elements of the gripping device, which preferably compresses the lifted sheet stack / stack of valuable documents against the stacking direction. In case of pre-compression as in step d0), the compression by the gripping device is a further compression operation performed in addition to the pre-compression. During compression, the gripping device presses the sheet stack / stack of valuable documents together against the stacking direction, for example until it is reduced to a pre-determined stack height or until the gripping device exerts a certain gripping force or a certain counter force exerted by the sheet stack / stack of valuable documents is reached.

[0047] The stacking of further sheets / valuable documents by the stacker wheels on the further stack of sheets / valuable documents positioned on the deposition platform as in step c) is preferably started before the introduction of the gripping device as in step d), i.e. also before the removal of the stack of sheets / valuable documents positioned on the lifting platform from the distribution area by the gripping device as in step e). This has the advantage that the stacking by the stacker wheels only has to be interrupted for a short period of time and the stacking of the further stack of sheets / valuable documents does not have to wait for the removal of the (previous) stack of sheets / valuable documents. Further sheets / valuable documents can be stacked on the further stack of sheets / valuable documents positioned on the deposition platform as in step c) while the gripping device is being introduced into the distribution area (step d)) and / or while the stack of sheets / valuable documents formed on the lifting platform is being removed from the distribution area by the gripping device (step e)).

[0048] Depending on preference, the gripping device, after removal of the sheet stack / stack of valuable documents as in step e), places the removed sheet stack / stack of valuable documents in a further step e*) in a sheet container / valuable documents container, which container is located in the immediate vicinity of the gripping device. When steps a) to g) are repeated, in particular when the removal step e) is repeated, the further sheet stack / stack of valuable documents removed from the distribution area is, for example, placed by the gripping device in the same sheet container / valuable documents container as the (preceding) sheet stack / stack of valuable documents, in particular in a different storage area of ​​this sheet container / valuable documents container from the (preceding) sheet stack / stack of valuable documents.

[0049] Depending on preference, the control device and / or the sheet handling device / valuable document handling device are made to trigger the above-mentioned steps. A control device for this comprises, for example, a processor, which executes software for triggering the above-mentioned steps and communicates with correspondingly activated adjustment devices of the components to be moved (e.g. lifting platform, stacking platform, gripping device). The control device also communicates, for example, with a control device of the sheet handling device / valuable document handling device, which controls the processing of the sheets / valuable documents, in particular the transport and stacking.

[0050] In particular, the control device and / or the sheet handling device / valuable document handling device may - the stacking of sheets / valuable documents by the stacker wheels onto the stack of sheets / valuable documents formed on the lifting platform is interrupted before the introduction of the stacking platform and, where appropriate, the lifting platform continues to be lowered downwards while the stacking is interrupted; and / or - after the introduction of the stacking platform, by means of the stacker wheel, starting to stack further sheets / valuable documents onto the stacking platform located directly below the stacker wheel, forming a further stack of sheets / valuable documents on the stacking platform; and / or - lowering the lifting platform downwards during and / or after stacking of sheets / valuable documents onto the stack of sheets / valuable documents positioned on the lifting platform, in particular while the stacker wheels are depositing the sheets / valuable documents onto the stack of sheets / valuable documents, and / or - the gripping device lifts the stack of sheets / stack of valuable documents between two gripping elements of the gripping device and compresses the lifted stack of sheets / stack of valuable documents against the stacking direction; and / or - before the introduction of the gripping device into the dispensing area, the sheet stack / stack of valuable documents deposited on the lifting platform is pre-compressed between the lifting platform and the stacking platform in the opposite stacking direction, during the pre-compression operation the sheet stack / stack of valuable documents deposited on the lifting platform is clamped and pressed together between the lifting platform and the stacking platform, the lifting platform, for example together with the sheet stack / stack of valuable documents deposited thereon, is raised in a direction towards the stacking platform in order to clamp the sheet stack / stack of valuable documents between the lifting platform and the stacking platform, and after clamping of the sheet stack / stack of valuable documents, the lifting platform is continued in order to compress the sheet stack / stack of valuable documents in the opposite stacking direction between the lifting platform and the stacking platform; and / or - the introduction of the gripping device and the removal of the sheet stack / stack of valuable documents by the gripping device while a further sheet stack / stack of valuable documents is being formed or stacked on the stacking platform, where appropriate also ensuring that a pre-compression is carried out; and / or - by means of the stacker wheels, the stacking of sheets / valuable documents onto a further stack of sheets / valuable documents located on the deposition platform is initiated before the introduction of the gripping device and / or before the removal by the gripping device of the stack of sheets / valuable documents located on the lifting platform from the dispensing area. It is made like this.

[0051] The sheet processing device may be a device for processing sheet-like electrode elements designed to form an electrode element stack. The sheets mentioned in this application are then sheet-like electrode elements. The term "sheet-like electrode element" is understood to mean an electrode element having a surface area much larger than its thickness, for example the length and width of which are at least ten times the thickness.

[0052] The sheet-like electrode elements are, for example, electrode elements for electrochemical energy storage or energy converters. In the electrode element stack, not only similar sheet-like electrode elements but also different sheet-like electrode elements may be stacked. The sheet-like electrode elements may be, for example, monocells, anodes, cathodes, separators, anode-separator combinations, cathode-separator combinations, or anode-separator-cathode-separator combinations.

[0053] Processing of sheet-like electrode elements in a sheet processing device designed to form an electrode element stack may include transporting and stacking the sheet-like electrode elements and, where appropriate, verifying the sheet-like electrode elements. Correspondingly, the device may have one or more transport devices, which are used to transport the sheet-like electrodes (e.g. past a sensor for verifying them) and to transport them to a stacker wheel that stacks the sheet-like electrode elements. The device may, for example, be one used for the production of sheet-like electrode elements or batteries.

[0054] The sheet processing device may be a valuable document processing device designed to process valuable documents, in particular to verify and, where appropriate, to sort the valuable documents. The sheet processing device has, for example, one or more transport devices, which are used to transport the valuable documents past a sensor for verifying the valuable documents and to transport the valuable documents to a stacker wheel for stacking the processed valuable documents. The valuable document processing device also has, for example, a separator device, which is used to separate the valuable documents from the initial stack and send them to one of the transport devices. Each stack of processed valuable documents is distributed in a distribution area of ​​the valuable document processing device. The valuable documents are, for example, banknotes, checks, identification documents, but the invention relates to any type of valuable documents.

[0055] The control device can be configured to control the gripping of the stack of sheets / stack of valuable documents deposited in the dispensing area and the deposition of the stack of sheets / stack of valuable documents into the sheet container / valuable document container by the gripping device.

[0056] The sheet container / valuable document container may, for example, have at least two receiving portions, and the control device may be designed to control the movement and / or gripping device of the sheet container / valuable document container so that multiple stacks of sheets / valuable documents dispensed by the sheet processing device / valuable document processing device are deposited one after the other into different receiving portions of the same sheet container / valuable document container.

[0057] The sheet processing device / valuable document processing device may also have one or more stuffing devices configured to stuff a stack of sheets / valuable documents dispensed from the sheet processing device / valuable document processing device into a sheet container / valuable document container, the stuffing devices being movable to and / or docked and / or fastened to the sheet processing device / valuable document processing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0062] Fig. 1a shows a processing device 60 for valuable documents according to an exemplary embodiment, which is made to sort, count and / or verify the valuable documents and, for this purpose, to provide the processed valuable documents for removal by a grabber (positioned under the cover of the stuffing device 1) or, if appropriate, to distribute them in one of its distribution compartments 63, 64. The grabber can transport a stack of removed valuable documents, for example, to a valuable document container, which is provided to the stuffing device 1. The valuable documents can be automatically inserted, using the insertion module 10, into the insertion compartment 61 of the processing device 60 for valuable documents, where they are removed in a stack from the valuable document container. The processing device 60 for valuable documents is used, for example, in a cash center.

[0063] The valuable documents provided to the insertion section 61 of the valuable document processing device 60 are individually extracted from the insertion section using a separator and transported along a transport path past one or more sensors to the valuable document processing device 60 (not shown). In the process, physical properties of the valuable documents are detected and converted into corresponding sensor signals, which are used by a control and evaluation device of the valuable document processing device 60 to identify and verify the valuable documents, for example with regard to quality, denomination, authenticity or condition. Deflectors arranged along the transport path are controlled such that, depending on the result of the identification or verification, the valuable documents are transported to different distribution sections 63, 64 or distribution areas 62, from where they are removed by a gripping device 30; see FIG. 1b. Adjacent to the distribution sections 63, 64 there may be, for example, a banderoling device and / or a wrapping device for the formed stack of valuable documents.

[0064] Valuable documents transported to the distribution area 62 may be rejected by the valuable document processor 60 during validation, e.g. rejected valuable documents, whereas valuable documents accepted during validation are deposited in the distribution compartments 63, 64. However, as an alternative, it is also possible to transport banknotes accepted during validation to the distribution area 62. It is also possible to provide several such distribution areas 62 in one valuable document processor 60. Upstream of the distribution compartments 63, 64 of the valuable document processor 60 and upstream of the distribution area 62, the valuable document processor 60 has respective stacker wheels 65 which can be used to stack valuable documents for distribution.

[0065] The stuffing device 1 is used to stuff a valuable document container 5 with a stack of valuable documents, for example a valuable document stack 40 provided to and deposited in a distribution area 62 of a valuable document processing device 60. For this, the (empty or partially full) valuable document container 5 to be stuffed is fed manually or automatically to the stuffing device 1 at its feed interface 2 in the form of a feed opening; see FIG. 1b. The container 5 is further divided by a separating element into a number of receiving parts, one of which, 6a, is shown in FIG. 2. The fed container 5 is then transported using a transport device of the stuffing device 1 to a stuffing area 3 of the stuffing device 1, where the valuable document stack is stuffed; see FIG. 2. After the stuffing operation, the stuffing device transports the containers 5 stuffed with the stacks of valuable documents from the stuffing area 3 of the stuffing device to a distribution interface 4 in the form of a distribution outlet to provide the containers 5 for manual removal from the stuffing device 1 or, if appropriate, for automatic transport of the stuffed containers by a conveyor belt. The movement of the containers 5 through the stuffing device is controlled by a control device 80 of the stuffing device; see Fig. 1b. The transport path of the containers in the stuffing device 1 may be formed in such a way that the containers are turned by 90° (horizontally or vertically) twice on their transport path from the feed interface to the distribution interface.

[0066] Each of the containers 5 to be stuffed has one or more receiving parts, each designed to receive a stack of valuable documents. Depending on preference, the containers or the receiving parts are open at their top, so that the stack of valuable documents can be placed into the container from above. The container 5 can have at least two receiving parts along its longitudinal extent, designed such that the control device 70 controls the gripping device 30 and, where appropriate, the transport device of the stuffing device, so that, one after the other, several stacks of valuable documents distributed by the valuable document processing device, i.e. formed into a pile one after the other on the lifting platform 22, are deposited in different receiving parts of the same container 5 positioned in the stuffing area.

[0067] The gripping device 30 has two gripping elements 31, 32 which are controlled by a control device 70 and which can be moved away from and towards each other by a motor to grip each stack of valuable documents between the two gripping elements 31, 32; see Figure 2. In order to be able to grip stacks of valuable documents of quite different sizes and deposit them in the container, gripping devices of different opening widths can be provided, such that the gripping elements of the gripping device are moved apart.

[0068] The control device 70 may also be designed to control the transport device of the stuffing device 1. If different container types are used, with one or more receiving areas at different positions along the longitudinal direction of the container and / or one or more receiving areas of different lengths, the control device 70 and / or the control device of the valuable document processing device may have available information regarding the predetermined positions and, if appropriate, lengths of the receiving areas depending on the container type. Information regarding the container type of each container to be stuffed may be preset or set by the operator (if appropriate, individually for each container) or may be automatically determined based on the identification data of the container (if appropriate, individually for each container). The control device 70 thus controls the opening width of the gripping element based on the container type and, if appropriate, on the respective receiving areas to be stuffed (for container types in which there are receiving areas of different sizes, as is known).

[0069] In the distribution area 62 of the valuable document handling device 60, directly below the stacker wheels 65, there is a rake-like lifting platform 22, on which valuable documents can be stacked by the stacker wheels 65 to form a stack of valuable documents, and a rake-like stacking platform 20 is temporarily introduced above the lifting platform (see Figure 2), on which valuable documents can be temporarily stacked by the stacker wheels 65.

[0070] An exemplary embodiment for dispensing a stack 40 of valuable documents from a valuable document handling device 60 and removing the stack by a gripping device is described in Figures 3a-l below.

[0071] FIG. 3a shows the distribution area 62 at a point when several valuable documents have been stacked on the deposition platform 20 by the stacker wheels 65 to form a single stack of valuable documents and the lift platform 22 is just moving up onto the deposition platform 20.

[0072] Optionally, a pause is incorporated in the stacking by the stacker wheels 65 in order to transfer the stack of valuable documents from the lifting platform 22 to the depositing platform 20 as steadily as possible. For this purpose, the control device 70 can cause a pause in the stacking by the stacker wheels 65 once the lifting platform 22 has reached directly the underside of the depositing platform 20, for example as a result of a corresponding signal to the control device of the valuable document processing device 60. So, immediately after the start of this pause in the stacking by the stacker wheels 65, the control device 70 causes the depositing platform 20 to be pulled backwards into the device 60 by the adjustment device 37, for example a motor, to unload the further stack 40 of valuable documents deposited on the depositing platform at the back wall 21, which belongs to the distribution area 62 and is located behind the depositing platform 20 (see FIG. 2), thus depositing the stack from the depositing platform 20 onto the lower lifting platform 22. 4a, 4b show the movement of the deposit platform 20 backwards through the back wall 21 of the distribution area 62 (the stack of valuable documents is not shown). 4a and 3b show the moment when the deposit platform 20 is partway back, and 4b shows the moment when it has been moved out of the distribution area 62. To allow a lateral movement backwards away from the deposit platform 20 through the back wall 21 of the distribution area 62, the back wall has openings 38 (see figs. 4a, b), which complement the fingers of the rake-like deposit platform 20 so that it can pass through the openings 38. In fig. 3c, the deposit platform 20 has already been completely back and is positioned behind the back wall 21 of the distribution area 62. The stack of valuable documents 40 has therefore been transferred to the lifting platform 22.

[0073] Once the stack of valuable documents has been transferred to the lifting platform 22, the optional pause in stacking by the stacker wheels 65 ends, and the stacker wheels 65 continue stacking valuable documents onto the stack of valuable documents 40 deposited on the lifting platform. For this purpose, the control device 70 sends a corresponding signal to the controller of the valuable document processing device 60, which then transports the processed valuable documents back to the stacker wheels 65.

[0074] To provide space for the accumulating valuable documents, the lifting platform 22 together with the valuable document stack 40 is lowered step by step or continuously downwards during the stacking operation by the stacker wheels 65; see FIG. 3d. This readjustment operation is controlled by the controller 70 based on a signal from a capacitive sensor 36 located on the side wall of the distribution area 62 directly below the stacker wheels 65 and detecting the valuable document stack 40; see FIG. 2.

[0075] Thereafter, the valuable documents continue to be stacked on the valuable document stack 40 by the stacker wheels 65 until an introduction condition is met. The introduction condition used can be, for example, that the valuable document stack 40 is at least a certain number of valuable documents (e.g. 500) and / or that the lifting platform 22, while being lowered, has reached a certain position, e.g. a lower stop, in the lower part of the distribution area 62 and / or that the upper stack end of the valuable document stack 40 is positioned below a certain position, which is monitored using the light barrier 35; see Fig. 3e. Once the introduction condition is met, the stacking platform 20 is introduced into the distribution area 62 of the valuable document handling device. For this purpose, the stacking platform 20 is brought from the rear through the rear wall of the distribution area 62 to its position directly below the stacker wheels 65; see Fig. 3f.

[0076] For the lateral introduction of the depositing platform 20, a further pause is preferably incorporated in the stacking by the stacker wheels 65 to avoid a lateral collision of the laterally introduced depositing platform 20 with a valuable document currently to be deposited. For example, the valuable document handling device 60 pauses the stacking by the stacker wheels 65 once the stack 40 of valuable documents comprises at least a certain number of valuable documents (e.g. 500). As an alternative, however, the further pause in the stacking may be omitted, for example when the depositing platform 20 is brought into position very quickly and / or when the exact moment at which the introduction occurs is purposefully set between two valuable documents to be stacked by the stacker wheels 65.

[0077] This optional pause of the stack for introducing the deposition platform 20 and / or the above-mentioned optional pause of the stack for transferring the stack of valuable documents from the deposition platform 20 to the lifting platform 22 may include a pause for separation and / or processing by the valuable document processing device. However, depending on preference, the valuable document processing device 60 continues to separate and process the valuable documents during the pause of the stacking by the stacker wheel 65 and transports the valuable documents separated and processed during the pause of the stacking to another target location of the valuable document processing device 60, for example into another stacker / into another distribution area / to a shredder of the valuable document processing device 60. The associated pause of the stacking is therefore, so to speak, only incorporated individually in this stacker wheel 65.

[0078] After lateral introduction of the stacking platform 20 directly below the stacker wheel 65: see FIG. 3g, further valuable documents can be stacked by the stacker wheel 65 onto the stacking platform 20 positioned directly below the stacker wheel (instead of the lifting platform 22), forming a further stack 41 of valuable documents on the stacking platform 20.

[0079] The lowering of the lifting platform 22 together with the stack of valuable documents 40 located thereon ends once the lowering lifting platform 22 reaches a certain position in the lower part of the distribution area 62, e.g. a lower stop, and / or once the upper stack end of the stack of valuable documents 40 is located below said certain position (which is monitored using the light barrier 35); see Figs. 3f, 3g. The stack of valuable documents 40 is moved downwards using the lifting platform 22 and is therefore presented for removal by the gripping device 30. The stack of valuable documents 40 is thus removed from the distribution area 62 by the gripping device 30.

[0080] However, before the removal of the stack of valuable documents 40 by the gripping device 30, it is also possible, optionally, to pre-compress the stack of valuable documents 40 formed on the lifting platform. This pre-compression step is carried out, for example, when it is found that the number of known valuable documents in the stack of valuable documents 40 tends to be too high (for example in the case of rejected valuable documents), so that the height of the stack is higher than the gripping device can grasp. In the pre-compression operation, the lifting platform 22 together with the stack of valuable documents 40 deposited on it is moved upwards again in the direction towards the deposition platform 20 until the stack of valuable documents 40 presses against the deposition platform 20 from below, so that the stack of valuable documents is compressed between the deposition platform 20 and the lifting platform 22; see FIG. 3h. The pre-compression reduces the height of the stack to an extent below the maximum opening width of the gripping elements 31, 32 of the gripping device 30. During pre-compression, further valuable documents can continue to be stacked onto the stacking platform 20 by the stacker wheels 65 .

[0081] To remove the stack of valuable documents 40, the gripping device 30 engages with its upper gripping element 31 in the groove of the rake-like depositing platform 20 and with its lower gripping element 32 in the groove of the rake-like lifting platform 22; see FIG. 3i. To lift the stack of valuable documents firmly, the gripping device 30 further compresses the already pre-compressed stack of valuable documents some more, for example until it reaches a certain counterforce exerted by the stack of valuable documents; see FIG. 3j. The gripping device 30 advances the stack of valuable documents 40 deposited on the lifting platform 22 from the distribution area 62 by means of its gripping elements 31, 32, thus removing the stack of valuable documents 40 from the lifting platform 22 and out of the distribution area 62.

[0082] By means of a downward pivoting movement (rotation about axis A; see Fig. 2, Fig. 3k), the gripping device 30 brings the stack 40 of valuable documents into a lowered position directly above the stuffing position 13 of the valuable document container 5 arranged in the stuffing area 3; see Fig. 3l. Previously, the receiving part 6a of the valuable document container into which the stack of valuable documents is to be placed has been positioned in the stuffing position 13.

[0083] The lifting platform 22, now free of the stack of valuable documents, meanwhile moves upwards again in a direction towards the deposition platform 20; see Figures 3k, 3l. The stack 40 is removed from the distribution area 62 by the gripping device 30, and while the lifting platform is rising, further valuable documents can continue to be stacked on the deposition platform 20 to form a further stack 41 of valuable documents; see Figures 3k, 3l.

[0084] Once the lifting platform 22 has reached the top of the deposition platform 20, a further stack 41 of valuable documents can be transferred from the deposition platform 20 onto the lifting platform 22, as described above in relation to Figures 3b, 3c.

[0085] Thus, the process described with respect to stack 40 of valuable documents is repeated for further stacks 41 of valuable documents to deposit more valuable documents into the further stacks 41 of valuable documents, after which the final stacks 41 of valuable documents are removed from the lifting platform 22 by the gripping device 30, out of the distribution area 62 and into the container 5.

[0086] Once the gripping device has reached the lowered position, it is lowered using the linear drive 34 (see FIG. 2) from the lowered position shown in FIG. 3l down to the receiving part 6a of the valuable document container, where the two gripping elements 31, 32 together with the stack 40 of valuable documents enter. The downward movement is stopped and the two gripping elements 31, 32 open slightly to release the stack 40 of valuable documents, thereby depositing it in the receiving part 6a of the valuable document container 5; see FIG. 3f. The gripping device is then moved upwards again out of the container 5 and is available to deposit the next stack of valuable documents, which is the stack to be next deposited on the lifting platform 22. The depositing of the next stack of valuable documents into the other receiving parts 6b-f of the valuable document container 5 is achieved in an analogous manner.

[0087] When the stack 40 of valuable documents is released, the gripping elements 31, 32 are moved away from each other to an opening width along the longitudinal direction of the container 5 that is equal to or somewhat smaller than the length of the respective receiving portions 6a-f. The separating element 6 (see FIG. 3a) present in the container 5 may have grooves on the side facing the deposited stack of valuable documents, the gripping elements 31, 32 entering these grooves to release the stack of valuable documents, but in doing so are intended to gently contact the stack.

[0088] In order to allow stacks 40 of valuable documents of different sizes to be placed in the receiving parts on different sides, different opening widths can be provided for the gripping elements 31, 32 to move away from each other when the respective stacks 40 of valuable documents are being released. For example, it can be provided that - in the same or different containers 5 - several receiving parts of different lengths may be used. To this end, the control device 70 of the gripping device controls the movement of the gripping elements 31, 32 away from each other so that the opening width when releasing the stacks 40 of valuable documents is adapted to the length of the respective receiving part. The opening width when releasing the stacks 40 of valuable documents is preferably selected such that the gripping elements 31, 32 do not hit the separating element 6 of the container 5 when moving away from each other. The opening width of the gripping elements can be varied continuously or discretely. For example, the opening width can be varied continuously by a stepping motor for the movement of the gripping elements 31, 32. However, in this exemplary embodiment, the gripping device 30 has a number of predefined opening widths by means of a number of mechanical rams which mechanically define the extent of movement of the gripping elements 31, 32 away from one another when releasing the stack 40 of valuable documents, the position of which is controlled by the control device 70 using the stop magnets 33; see FIG. 2a.

[0089] The stage-by-stage movement of the banknote container 5 by the stuffing device 1 allows the gripping device 30 to deposit several stacks 40 of valuable documents one after the other from the valuable document handling device into the different receiving sections 6a, 6b etc. of the valuable document container 5. After being stuffed into the receiving section 6a, the container 5 is advanced until the receiving section 6b is positioned in the stuffing position 13. The next stack of valuable documents from the valuable document handling device 60 is then deposited into the receiving section 6b as explained in relation to Figures 3a-l. In this way the receiving sections 6a-f of the valuable document container are stuffed one after the other with stacks of valuable documents.

[0090] Thanks to the stepwise transport of the different receiving portions 6a-f to the same loading position 13, the gripping device 30 does not have to approach the different loading positions, but instead can always approach the same predefined loading position 13 to load the different receiving portions 6a-f. Therefore, the gripping movements are less complicated and therefore require less space. Once all or the intended number of the receiving portions of the container 5 have been loaded, the container 5 is transported in the distribution transport direction (-y) along the distribution portion 14 up to the distribution interface 4, where it can be removed manually or automatically.

[0091] Each container positioned in the stuffing area can be transported stepwise by the transport device of the stuffing device along the transport direction through the stuffing device 1 so that successive different (e.g. two or more) receiving portions of the same container are positioned at predetermined stuffing positions 13 and remain there temporarily until the gripping device 30 deposits respective stacks of valuable documents in the respective receiving portions of the container.
