Definitions

• the invention relates to a device for deflecting flat, rectangular sheet material, in particular of sheet-shaped documents of value such.
• B. banknotes from a first Blattguttransportrange with a first transport direction to a Blattguttransportrange with a different transport direction to the first transport direction, in particular for changing the transport direction by 90 ° or 180 °.
• the invention further relates to a device for processing sheet-shaped value documents, in particular banknotes, with such a deflection device between a first and a further transport path with different transport directions.
• Deflection devices in which sheet material z. B. are deflected by 90 ° or 180 ° are used for example in banknote processing devices.
• conventional deflection devices are either not suitable for redirecting an uninterrupted flow of banknotes at high throughput speeds, or are at least comparatively expensive in terms of space requirements and / or their structural design.
• a multi-module banknote processing device is known, in which the deflection device according to the invention described below is advantageously used.
• This banknote processing device is configured as a tabletop device and serves to separate the banknotes of a banknote stack inserted by an operator into an input compartment, to check the individual banknotes for characteristic features by means of suitable measuring and analyzing devices, to sort the checked banknotes according to the respective check result and / or after sorting result in a predetermined output tray by means of a Spiralfachstaplers stack.
• the output compartments are partially juxtaposed and partly arranged one above the other in such a way that all output compartments get as good as possible from the Operator are reachable.
• the banknotes are basically transported transversely within the modules.
• a disadvantage of this banknote processing device is that a very voluminous, formed of guide plates and twisted conveyor belts transport path is provided to rotate the banknotes so that they can be transported laterally to the adjacent modules in transverse orientation.
• the banknotes are first rotated by 90 ° about their transport axis by means of the twisted conveyor belts, then the banknotes are deflected by an axis lying transversely to the transport direction by 90 ° and transferred in this orientation into the adjacent module. There, the banknotes are returned to their original orientation by first being deflected again by 90 ° and then again rotated by 90 ° about the transport axis by means of the twisted conveyor belts.
• This method of transferring the banknotes from one module to an adjacent module while maintaining the sheet orientation relative to the transport direction is very expensive in terms of space and structural design, but at least it allows to redirect uninterrupted banknote stream at a high throughput speed.
• DE 19632224 A1 also describes a device for deflecting sheet material. Therein it is proposed to dispense with deflection rollers in the deflection region and instead to extend transport belts of the feeding and discharging transport sections each over the deflection zone such that the banknote is withdrawn from the deflection zone by means of the transport belt of the discharging transport route.
• the conveyor belt of the laxative transport path is always pressed against the take-off plane of the deflection, when the print plane has been fed a bill.
• a particular embodiment provides that the consecutive banknotes are alternately forwarded to a first or a second withdrawal plane by means of a switch, so that the next succeeding sheet is already fed to the second removal plane even before the previous sheet has been completely deducted from the first level of withdrawal and forwarded. Accordingly, two trigger systems are required, one for each trigger level. To be sure, it is possible in this way to redirect an uninterrupted flow of banknotes at a high throughput speed. However, the provision of multiple exhaust systems requires a high design effort.
• Object of the present invention is therefore to provide a device for deflecting sheet material, such as.
• This object is achieved by a deflection device having the features of the independent claim 1.
• advantageous embodiments and further developments of the invention are given, in particular a device for processing sheet-shaped Wertdokumen- th with such a deflection device.
• the deflecting device is characterized, inter alia, by the fact that the sheet stock orientation does not change relative to the transport direction when deflecting the sheet material. Instead, sheet material fed into the transverse alignment in the first transport path is deflected in this orientation and forwarded to the subsequent transport path.
• a stationary guide body with a first transport plane whose sheet material still to be deflected can be fed in a first transport direction, and a second transport plane parallel to the first transport plane, in order to forward already deflected sheet material in a direction different from the first transport direction.
• the two transport planes are connected via a rectilinear deflection edge for deflecting the sheet material from the first to the second transport plane.
• the deflecting edge is arranged obliquely to the transport direction, wherein the skew angle of the deflecting edge is identical relative to the feeding transport direction and relative to the discharging transport direction.
• the skew angle ⁇ i enclosed between the deflecting edge and the two transport directions is thus ov ⁇ / 2 in each case.
• the deflection device also includes a transport device for transporting the sheet material along at least one of the transport planes in the respective transport direction.
• the sheet material transported and deflected in this way does not change its orientation during the deflection. Only the transport direction and, of course, the transport level change from a first transport level to one to parallel second transport plane. The distance between the two transport planes depends on the width of the deflection and can be kept low.
• Such a device can be made structurally very simple, in particular when the guide body is designed as a deflection plate with a back plane forming the first transport plane and a front side forming the second transport plane.
• a deflection by 90 ° can be achieved by means of such a deflection device when the skew angle P 1 of the deflection edge is 45 °.
• the 90 ° - deflection can advantageously at an interface between two processing modules of the banknote processing apparatus described above, z. B. in vertical alignment on the module backsite, be arranged to direct sheet material from a module to an adjacent module.
• the second transport plane has a second rectilinear deflection edge in order to divert the already deflected sheet material again into a third transport direction, which lies in a third transport plane which is adjacent to the second
• Transport plane is parallel. Similar to the first deflecting edge is arranged obliquely at an identical angle to the first and the second transport direction, the second deflecting edge is aligned at an identical angle ß 2 obliquely to the second and the third transport direction.
• This skew angle ⁇ 2 is in turn half as large as an angle 012, where ⁇ 2 denotes the angle by which the third transport direction deviates from the second transport direction.
• the third transport direction can lie in the same transport plane as the first transport direction.
• the formation of the guide body as a conversion is particularly preferred.
• a Bactuumlen- angle can be set ß, which is twice as large as the sum of the skew angle ßi and ß 2 .
• a total deflection by 90 ° while maintaining the transport plane can be achieved if the skew angle ßi and ß 2 in the sum amount to 45 °.
• a total deflection ß of 180 ° results, however, when the skew angles ß ⁇ and ß 2 in the sum of 90 °. In the latter case, therefore, the Zugartransportides opposite to the Abrawtransportides and is parallel to it.
• Such a 180 ° deflection device can be used, for example, as an interface-bridging element between two banknote processing modules, for example in a vertical orientation across modules at the module backsides.
• this deflecting device with two deflecting edges comprises a switch for selectively feeding the sheet material deflected at the first deflecting edge to the second deflecting edge.
• the sheet material In the inactive state, the sheet material is transported along the second transport direction over the switch, so that only a single deflection takes place at the first deflection edge, for example by 90 °.
• the switch In the active state, however, the switch directs the sheet material to the second deflection edge, and there is a second deflection, for example by another 90 °, so that by means of the switch either a total deflection by 90 ° or 180 ° is adjustable.
• the second transport plane has two overlapping sections in an area arranged downstream of the switch, of which a first section leads to the second deflection edge.
• the sheet material is thus transported over this first section when the switch is active. Is the switch there against inactive, the sheet material on the switch and the second section without transport direction change is transported on.
• the sheet material transported further via the switch can also be deflected at the end of the first transport plane via a third rectilinear deflection edge in a similar manner as has already been described with reference to the second deflection edge.
• the oblique position angle ⁇ 3 of the third deflecting edge is identical to the inclination angle ⁇ 2 of the second deflecting edge, so that the transport direction of sheet material deflected around the second and the third deflecting edge is identical, but shifted in parallel.
• the sheet material transported along a transport path can be divided into two transport paths, which can preferably be arranged parallel to one another and in particular parallel to the first transport path and lie in a common transport plane if the widths of the deflection edges are selected to be identical.
• the second transport plane can be further extended in the direction of the second transport direction and can have additional switches and deflection edges in order to be able to serve further transport routes in accordance with the number of switches or deflection edges.
• Such a device with a transport path for sheet material supply and two or more, preferably parallel, transport lines for the Blattgutab Entry is particularly suitable for the Blattgutbearbeitungsvorrich- described above, in which a plurality of output compartments are arranged side by side.
• the deflection device further comprises a transport device for actively transporting the sheet material along at least individual transport planes.
• a transport device for actively transporting the sheet material along at least individual transport planes.
• a transport device is used with which the sheet material is held during transport in contact with the transport planes, in particular pressed against the transport planes.
• On integrated in the baffle or the baffle transport can then be dispensed with.
• the sheet material can be moved along the individual transport planes by means of one or more conveyor belts and / or transport rollers. It is advisable to use a conveyor belt for transporting the sheet material along the second transport plane and around at least one deflection edge, that is to say, for example, around the first deflection edge or the last deflection edge.
• the conveyor belt then also assumes a guiding function for the sheet material to be deflected in the region of the deflection edge, so that on the one hand a reliable sheet material guidance is ensured and on the other hand it is possible to dispense with separate guide elements in the area of the deflection edge.
• the sheet material can be transported by means of the conveyor belt both around the first deflection edge and around the last deflection edge, ie about the second, third or further deflection edge.
