Ein anderes Transportsystem umfasst mehrere parallele Bänderebenen 12, wobei die einander entsprechenden Rollen 13, 14, 15, 20, 21, 24 oder 25 aus jeder Bänderebene 12 auf gemeinsamen Achsen sitzen, die senkrecht auf den Bänderebenen 12 stehen. Anstelle von Bändern 17, 26 mit einem rechteckigen Querschnitt sind, insbesondere für das Band 17, auch Seiten mit einem kreisförmigen Querschnitt verwendbar.Another transport system comprises a plurality of parallel belt levels 12, the corresponding rollers 13, 14, 15, 20, 21, 24 or 25 from each belt level 12 being seated on common axes which are perpendicular to the belt levels 12. Instead of bands 17, 26 with a rectangular cross section are, especially for the band 17, pages with a circular cross section can be used.

In der Transportrichtung kann unmittelbar nach der Eingangsebene 27 eine Prüfeinrichtung 29 angeordnet sein, die die in der Transportebene 16 die an ihr vorbeigeführten Blätter 3 abtastet und entsprechende Signale an einen Antrieb 30 mit seiner Steuereinrichtung 31 abgibt. Der Antrieb 30 ist z. B. auf eine der Endrollen 24, 25 gekoppelt und setzt die Bänder 17 und 26 und den Wagen 11 in Bewegung.In the transport direction, a test device 29 can be arranged immediately after the input plane 27, which scans the sheets 3 which are guided past it in the transport plane 16 and emits corresponding signals to a drive 30 with its control device 31. The drive 30 is, for. B. coupled to one of the end rollers 24, 25 and sets the belts 17 and 26 and the carriage 11 in motion.

Der Antrieb 30 kann auch direkt auf den Wagen 11 wirken, beispielsweise mit einem hier nicht gezeigten Seilzug oder mit einem auf dem Wagen 11 angeordneten Antrieb 30. In dieser Ausführung werden die Bänder 17 und 26 indirekt durch das Verschieben des Wagens 11 angetrieben.The drive 30 can also act directly on the carriage 11, for example with a cable (not shown here) or with a drive 30 arranged on the carriage 11. In this embodiment, the belts 17 and 26 are driven indirectly by moving the carriage 11.

Die Steuereinrichtung 31 ist mit verschiedenen Sensoren, wie z. B. mit der Prüfeinrichtung 29, verbunden und zur Steuerung des Antriebs 30 auf signalabhängige vorbestimmte Weise eingerichtet. Stellt beispielsweise ein hier nicht gezeigter Fühler in der ersten Eingangsebene 27 die Anwesenheit der Vorderkante des gegen den Wagen 11 transportierten Blatts 3 fest, übermittelt der Fühler ein Signal an die Steuereinrichtung 31, die ihrerseits den Antrieb 30 einschaltet. Der Antrieb 30 setzt das Endlosband 26 im Gegenuhrzeigersinn in Bewegung. Reibungskräfte in der Transportebene 16 übertragen die Bewegung des Endlosbands 26 auf das Band 17, wobei der den in der ersten Endstellung 9 wartende Wagen 11 in einer Bewegungsrichtung 32 auf die zweite Endstellung 10 zu beschleunigt wird. Die Bänder 17 und 26 befördern das in der Eingangsebene 27 erfasste Blatt 3 in der Bewegungsrichtung 32 mit der doppelten Geschwindigkeit des Wagens 11. Bei der ersten Führungsrolle 13 angekommen, wird das Blatt 3 mit seiner Vorderkante an das Band 17 angeschmiegt um 180° aus der Transportebene 16 in die Stapelebene 5 abgelenkt.The control device 31 is equipped with various sensors, such as. B. connected to the test device 29 and set up to control the drive 30 in a signal-dependent predetermined manner. If, for example, a sensor (not shown here) detects the presence of the front edge of the sheet 3 transported against the carriage 11 in the first input plane 27, the sensor transmits a signal to the control device 31, which in turn switches on the drive 30. The drive 30 sets the endless belt 26 in counterclockwise motion. Frictional forces in the transport plane 16 transmit the movement of the endless belt 26 to the belt 17, the carriage 11 waiting in the first end position 9 being accelerated in a direction of movement 32 towards the second end position 10. The belts 17 and 26 convey the sheet 3 detected in the input plane 27 in the direction of movement 32 at twice the speed of the carriage 11. Arrived at the first guide roller 13, the sheet 3 is nestled with its leading edge onto the belt 17 by 180 ° from the Transport level 16 deflected into the stacking level 5.

Die erste Endstellung 9 auf der Schiene 8 ist so vorbestimmt, dass, wie die Figur 2 zeigt, die Vorderkante des Blatts 3 nach dem Umlenken in die Stapelebene 5 bündig auf eine der ersten Eingangsebene 27 (Figur 1) nächsten Begrenzung 33 des Stapels 1 abgelegt wird. Die Weiterbewegung des Wagens 11 in der gleichen Bewegungsrichtung 32 wälzt das Blatt 3 um die erste äussere Führungsrolle 13 auf den Stapel 1 ab, wobei sich die Lage der Vorder- und Rückseite des Blatts 3 beim Stapeln vertauschen.The first end position 9 on the rail 8 is predetermined that, as shown in FIG. 2, the leading edge of the sheet 3, after being deflected into the stacking level 5, is placed flush on a boundary 33 of the stack 1 closest to the first input level 27 (FIG. 1). The further movement of the carriage 11 in the same direction of movement 32 rolls the sheet 3 around the first outer guide roller 13 onto the stack 1, the position of the front and back of the sheet 3 being interchanged when stacked.

Mit Vorteil weist der Wagen 11 zwischen der äusseren Führungsrolle 13 und der mittleren Führungsrolle 14 einen unmittelbar über der Stapelebene 5 angeordneten Ablenker 34 auf, da sich das Endlosband 26 an einer vorbestimmten Stelle des Umfangs der äusseren Führungsrolle 13 vom Band 17 abhebt. Der Ablenker 34 führt das Blatt 3 im Kontakt mit dem Band 17 aus der Transportebene 16 um die äussere Führungsrolle 13 herum in die Stapelebene 6 und lenkt auch relativ steife oder sehr weiche Blätter 3 sicher auf den Stapel 1, wo sie ohne Falten in der vorbestimmten Lage abgelegt werden. Anstelle einzelner Blätter 3 ist auch ein einige Blätter 3 umfassendes Bündel in einem Stapelvorgang stapelbar.Advantageously, the carriage 11 has a deflector 34 arranged directly above the stacking level 5 between the outer guide roller 13 and the middle guide roller 14, since the endless belt 26 lifts off the belt 17 at a predetermined point on the circumference of the outer guide roller 13. The deflector 34 guides the sheet 3 in contact with the belt 17 from the transport plane 16 around the outer guide roller 13 into the stacking plane 6 and also guides relatively stiff or very soft sheets 3 onto the stack 1, where they fold without folds in the predetermined one Location to be filed. Instead of individual sheets 3, a bundle comprising a few sheets 3 can also be stacked in a stacking process.

In der Figur 3 ist der Wagen 11 weiter bis in die zweite Endstellung 10 gefahren und das Blatt 3 ist auf dem Stapel 1 abgelegt. Ein mit der Steuerschaltung 31 verbundener Detektor 35 ist bei der zweiten Endstellung 10 zum Feststellen der Ankunft des Wagens 11 angeordnet. Auf ein Signal des Detektors 35 schaltet die Steuerschaltung 31 den Antrieb 30 um und der Wagen 11 bewegt sich in die erste Endstellung 9 (Figur 1) zurück. Ein hier nicht gezeigter, durch den Wagen 11 betätigter Taster stellt in der ersten Endstellung 9 die Ankunft des Wagens 11 fest und schaltet mittels der mit dem Taster verbundenen Steuereinrichtung 31 den Antrieb 30 aus. Der Detektor 35 und der Taster können z. B. als Lichtschranken oder als mechanisch betätigte Schalter ausgebildet sein.In Figure 3, the carriage 11 has continued to the second end position 10 and the sheet 3 is placed on the stack 1. A detector 35 connected to the control circuit 31 is arranged at the second end position 10 for determining the arrival of the carriage 11. Upon a signal from the detector 35, the control circuit 31 switches the drive 30 and the carriage 11 moves back into the first end position 9 (FIG. 1). A button (not shown here) operated by the carriage 11 determines the arrival of the carriage 11 in the first end position 9 and switches off the drive 30 by means of the control device 31 connected to the button. The detector 35 and the button can, for. B. be designed as light barriers or as a mechanically operated switch.

Diese Vorrichtung weist die Vorteile auf, dass pro Bandebene 12 nur zwei Bänder 17, 26 über die stationären Rollen 20 bis 25 (Figur 1) geführt sind, dass der Wagen 11 mit den Führungsrollen 13 bis 15 auf der Schiene 8 wegen seiner kleinen trägen Masse mit grossen Beschleunigungen verschiebbar ist und dass wenigstens eines der Bandenden 18, 19 ständig gegen den Stapel 1 gepresst ist, ohne eine Verschiebekraft auf das oberste Blatt 3 des Stapels 1 auszuüben.This device has the advantages that only two belts 17, 26 are guided over the stationary rollers 20 to 25 (FIG. 1) per belt level 12, that the carriage 11 with the guide rollers 13 to 15 on the rail 8 because of its small inert mass with high accelerations and that at least one of the band ends 18, 19 is constantly pressed against the stack 1, without exerting any displacement force on the top sheet 3 of the stack 1.

In der Figur 1 tastet die Prüfeinrichtung 29 beim Einziehen des Blatts 3 beispielsweise optisch oder magnetisch dessen Druckbild ab und vergleicht die Abtastwerte mit einem Satz gespeicherter Sollwerte. Nach Ablauf des Erkennungsvorgangs gibt die Prüfeinrichtung 29 über eine Leitung Annahme- oder Rückweisesignale an die Steuereinrichtung 31 ab.In FIG. 1, when the sheet 3 is drawn in, the testing device 29 scans its print image, for example optically or magnetically, and compares the samples with a set of stored target values. After the recognition process has ended, the test device 29 outputs acceptance or rejection signals to the control device 31 via a line.

Klassiert die Prüfeinrichtung 29 das Blatt 3 als nicht annehmbar, schaltet die Steuereinrichtung 31 mit Vorteil den Antrieb 30 um, bevor das Blatt 3 vollständig auf dem Stapel 1 abgelegt ist, da sich dann ein aufwendiges Blatterfassen vom Stapel 1 erübrigt. Durch ein Zurückfahren des Wagens 11 in die erste Endstellung 9 wird das Blatt 3 durch die Eingangsebene 27 hindurch aus der Transportebene 16 entfernt.If the testing device 29 classifies the sheet 3 as unacceptable, the control device 31 advantageously switches the drive 30 before the sheet 3 has been completely deposited on the stack 1, since then complex sheet picking from the stack 1 is unnecessary. By moving the carriage 11 back into the first end position 9, the sheet 3 is removed from the transport plane 16 through the entrance plane 27.

Dauert das Erkennen des Druckbildes länger als das Ueberfahren des Stapels 1 durch die mittleren Führungsrolle 14, ist auf der Schiene 8 über dem Stapel 1 ein vorbestimmter Haltepunkt eingerichtet, an dem der Wagen 11 das Ende des Erkennungsvorgangs abwartet, wobei sich das hintere Ende des vollständig von der Prüfvorrichtung 29 abgetasteten Blatts 3 noch in der Transportebene 16 zwischen den Bändern 17, 26 befindet und eine Rückgabe des Blatts 3 im Falle einer Rückweisung möglich ist.If the recognition of the printed image takes longer than the passing over of the stack 1 by the middle guide roller 14, a predetermined stopping point is set up on the rail 8 above the stack 1, at which the carriage 11 waits for the end of the recognition process, the rear end of the complete sheet 3 scanned by the test device 29 is still in the transport plane 16 between the belts 17, 26 and a return of the sheet 3 is possible in the event of rejection.

Nach Ablauf des Erkennungsvorgangs wird der Wagen 11 wieder in Bewegung gesetzt. Soll das Blatt 3 angenommen und gestapelt werden, gibt die Prüfvorrichtung 29 an die Steuereinrichtung 31 das Annahmesignal ab, damit der Wagen 11 in der gleichen Bewegungsrichtung 32 weiter fährt, bis der Stapelvorgang beendet ist. Bei einer Rückweisung des Blatts 3 bewirkt das Rückweisesignal ein Umsteuern des Antriebs 30. Der Wagen 11 fährt daraufhin in der zur Bewegungsrichtung 32 entgegengesetzten Richtung 36 zur ersten Endstellung 9 zurück und das Blatt 3 wird aus der Vorrichtung entfernt.After the recognition process, the carriage 11 is set in motion again. If the sheet 3 is to be accepted and stacked, the test device 29 outputs the acceptance signal to the control device 31 so that the carriage 11 continues in the same direction of movement 32 until the stacking process has ended. If the sheet 3 is rejected, the rejection signal causes the drive 30 to be reversed. The carriage 11 then moves in the direction opposite to the direction of movement 32 Direction 36 back to the first end position 9 and the sheet 3 is removed from the device.

Anstelle des aufwendigen Erkennens des Druckbildes auf dem Blatt 3 kann die Prüfeinrichtung 29 in einer einfacheren Ausführung als Lichtschranke ausgebildet sein, die in Verbindung mit der Steuereinrichtung 31 die Länge der Blätter 3 misst. Der Antrieb 30 ist vorzugsweise mit einem Schrittmotor ausgerüstet, wobei die Schalteinrichtung 31 anhand der Anzahl Schritte des Antriebs 30 während einer Bedeckung der Lichtschranke die Blattlänge berechnet und mit vorbestimmten Sollwerten vergleicht. Die Verwendung eines Zahnriemens für das Endlosband 26, der mit der angetriebenen Endrolle 24 bzw. 25 im Eingriff steht, unterdrückt allfällige Schlupffehler.Instead of the complex recognition of the printed image on the sheet 3, the testing device 29 can be designed in a simpler version as a light barrier, which measures the length of the sheets 3 in connection with the control device 31. The drive 30 is preferably equipped with a stepper motor, the switching device 31 calculating the sheet length on the basis of the number of steps of the drive 30 while the light barrier is being covered and comparing it with predetermined target values. The use of a toothed belt for the endless belt 26, which is in engagement with the driven end roller 24 or 25, suppresses any slip errors.

Die Vorrichtung ist in Bezug auf den Blattransport einfach symmetrisch aufbaubar, wobei für jede Bewegungsrichtung 32 bzw. 36 ein Satz der vorbestimmten Sensoren längs der Schiene 8 angeordnet ist. Sowohl in der einen Bewegungsrichtung 32 als auch in der ihr entgegengesetzten Richtung 36 kann das durch die Eingangsebene 27 bzw. 28 hindurch der Transportebene 16 zugeführte Blatt 3 von den Bändern 17, 26 erfasst und auf den Stapel 1 abgelegt werden. Das Blatt 3 in der Transportebene 16 und der Wagen 11 weisen zum Stapeln immer dieselbe Bewegungsrichtung 32 bzw. 36 auf. Ein wechselweises Zuführen der Blätter 3 durch die Eingangsebene 27 bzw. 28 hindurch verkürzt vorteilhaft den Stapelvorgang, da das unproduktive Zurückfahren des Wagens 11 in die erste Endstellung 9 wegfällt.The device can be constructed simply symmetrically with respect to the sheet transport, a set of the predetermined sensors being arranged along the rail 8 for each direction of movement 32 or 36. Both in one direction of movement 32 and in the direction 36 opposite to it, the sheet 3 fed through the entrance plane 27 or 28 to the transport plane 16 can be gripped by the belts 17, 26 and deposited on the stack 1. The sheet 3 in the transport plane 16 and the carriage 11 always have the same direction of movement 32 and 36 for stacking. An alternate feeding of the sheets 3 through the entrance level 27 or 28 advantageously shortens the stacking process, since the unproductive return of the carriage 11 to the first end position 9 is eliminated.

Die Haltestellen des Wagens 11 längs der Schiene 8 sind beispielsweise durch hier nicht gezeigte Sensoren festgelegt, die an den vorbestimmten Stellen angeordnet sind. Die Ausgangssignale der Sensoren wirken auf die Schalteinrichtung 31 und erlauben ein genaues Anfahren von vorbestimmten Stellen. Die Positionen der Sensoren sind z. B. mittels Stellmitteln längs der Schiene 8 verschiebbar angeordnet. Ist der Antrieb 30 mit dem Schrittmotor ausgerüstet, können die Haltestellen auch mittels Abzählen von Schritten festgelegt werden.The stops of the carriage 11 along the rail 8 are determined, for example, by sensors, not shown here, which are arranged at the predetermined locations. The output signals of the sensors act on the switching device 31 and allow an exact approach to predetermined points. The positions of the sensors are e.g. B. slidably arranged along the rail 8 by adjusting means. If the drive 30 is equipped with the stepper motor, the stops can also be determined by counting steps.

In der Figur 4 weist eine vor der Eingangsebene 27 angeordnete Zufuhrstrecke 37 mit Vorteil eine sich daran anschliessende Verzweigung 38 auf, deren Zweige 39 und 40 für das Zuführen der Blätter 3 (Figur 1) durch die beiden Eingangsebenen 27 und 28 hindurch mit der Transportebene 16 verbunden sind. Die Verzweigung 38 weist einen vorbestimmt zwischen den Zweigen 39 und 40 umschaltbaren Blattdurchgang 41 auf, der das von der Zufuhrstrecke 37 zugeführte Blatt 3 über den vorbestimmten Zweig 39 bzw. 40 in die Transportebene 16 leitet.In FIG. 4, a feed path 37 arranged in front of the input level 27 advantageously has a branching 38 adjoining it, the branches 39 and 40 thereof for feeding the sheets 3 (FIG. 1) through the two input levels 27 and 28 with the transport level 16 are connected. The branching 38 has a sheet passage 41 which can be switched between the branches 39 and 40 and which guides the sheet 3 fed from the feed path 37 via the predetermined branch 39 or 40 into the transport plane 16.

Die Steuereinrichtung 31 ist zum Erzeugen von Stellsignalen für die Verzweigung 38 eingerichtet, welche der Verzweigung 38 leitungsgebunden übertragen werden und die Stellung des Blattdurchgangs 41 bestimmen. Die Steuervorrichtung 31 schaltet den Blattdurchgang 41 beispielsweise nach jedem Blatt 3 um, damit für ein effizientes Stapeln die einzelnen Blätter 3 abwechslungsweise einem der Zweige 39, 40 zugeführt werden.The control device 31 is set up to generate actuating signals for the branch 38, which are transmitted to the branch 38 in a line-bound manner and determine the position of the sheet passage 41. The control device 31 switches the sheet passage 41, for example after each sheet 3, so that the individual sheets 3 are alternately fed to one of the branches 39, 40 for efficient stacking.

Beispielsweise ist die Prüfvorrichtung 29 an der Zufuhrstrecke 37 angeordnet, um das auf der Zufuhrstrecke 37 zur Verzweigung 38 transportierte Blatt 3 abzutasten und die Abtastwerte mit dem gespeicherten vorbestimmten Satz von Sollwerten zu vergleichen, wobei das Erkennen des Blatts 3 sowohl anhand des Druckbilds der Vorder- wie der Rückseite erfolgt. Ist das Annahmesignal mit einer Information über die erkannte Seite des Blatts 3 ergänzt, erzeugt die Steuereinrichtung 31 die vorbestimmten Stellsignale für die Verzweigung 38, damit der Blattdurchgang 41 mit Vorteil abhängig von der erkannten Seite des Blatts 3 auf den vorbestimmten Zweig 39 bzw. 40 umschaltbar ist.For example, the test device 29 is arranged on the feed path 37 in order to scan the sheet 3 transported to the branch 38 on the feed path 37 and to compare the sampled values with the stored predetermined set of target values, the recognition of the sheet 3 using the printed image of the front how the back is done. If the acceptance signal is supplemented with information about the recognized side of the leaf 3, the control device 31 generates the predetermined actuating signals for the branch 38 so that the leaf passage 41 can advantageously be switched over to the predetermined branch 39 or 40 depending on the detected side of the leaf 3 is.

Die Vorrichtung legt alle Blätter 3 auf dem Stapel 1 (Figur 1) geordnet ab, wobei die Blätter 3 die gleiche Seite der Platte 2 (Figur 1) zuwenden. Zum Beispiel werden alle Blätter 3, die die Prüfeinrichtung 29 anhand des Druckbilds der Vorderseite erkannt hat, über den Zweig 39 durch die Eingangsebene 27 hindurch in die Transportebene 16 geleitet. Die andern angenommenen Blätter 3 gelangen über den Zweig 40 mit einer 180°-Umlenkung 42 durch die Eingangsebene 28 hindurch in die Transportebene 16.The device places all the sheets 3 on the stack 1 (FIG. 1) in an orderly manner, the sheets 3 facing the same side of the plate 2 (FIG. 1). For example, all sheets 3, which the test device 29 has identified on the basis of the printed image on the front side, are guided via the branch 39 through the input plane 27 into the transport plane 16. The other assumed leaves 3 pass through the branch 40 with a 180 ° deflection 42 through the entrance level 28 into the transport level 16.

Zurückgewiesene Blätter 3 können über einen Rückgabezweig 43 der Verzweigung 38 in ein Rückgabefach 44 zurückgegeben werden.Rejected sheets 3 can be returned to a return compartment 44 via a return branch 43 of the branch 38.

In der Figur 5 weist die Vorrichtung zwei Stapel 1 auf, die in der Bewegungsrichtung 32 hintereinander unter der Stapelebene 5 angeordnet sind. Jeder Stapel 1 ist auf einer eigenen Platte 2 aufgestapelt und kann mittels einer eigenen Kassette 45, 46 unter der Stapelebene 5 hervorgezogen werden, um die gefüllte Kassette 45, 46 gegen eine leere auszutauschen. Beispielsweise umfasst jeder Stapel 1 Banknoten des gleichen Nennwerts, wobei die Anzahl hintereinander unter der Schiene 8 angeordneter Stapel 1 durch die Anzahl der zu stapelnden Nennwerte vorbestimmt ist.In FIG. 5, the device has two stacks 1, which are arranged one behind the other in the direction of movement 32 below the stack plane 5. Each stack 1 is stacked on its own plate 2 and can be pulled out from under the stacking level 5 by means of its own cassette 45, 46 in order to exchange the filled cassette 45, 46 for an empty one. For example, each stack comprises 1 banknotes of the same denomination, the number of stacks 1 arranged one behind the other under the rail 8 being predetermined by the number of denominations to be stacked.

Zwischen den Endstellungen 9 und 10 (Figur 1) weist die Schiene 8 für jeden Stapel 1 und für beide Bewegungsrichtungen 32 und 36 des Wagens 11 mit Vorteil vorbestimmte Startpositionen des Wagens 11 auf, damit die Vorrichtung die Blätter 3 entsprechend ihrer Eigenschaften auf die separaten Stapel 1 sortieren kann. Auf der Zufuhrstrecke 37 analysiert die Prüfvorrichtung 29 das Blatt 3 (Figur 1) und leitet an die Steuereinrichtung 31 ein dem Druckbild oder der Grösse des Blatts 3 entsprechendes vorbestimmtes Stapelsignal. Die Steuereinrichtung 31 ist zum Empfang des Stapelsignals und zum Steuern des Antriebs 30 in Abhängigkeit von den Stapelsignalen eingerichtet. Bevor das Blatt 3 die Eingangsebene 27 bzw. 28 erreicht, bewegt der Antrieb 30 den Wagen 11 in die vorbestimmte Startposition, damit das Blatt 3 nach dem Erfassen durch die Bänder 17, 26 auf den vorbestimmten Stapel 1 abgelegt wird.Between the end positions 9 and 10 (FIG. 1), the rail 8 advantageously has predetermined starting positions of the carriage 11 for each stack 1 and for both directions of movement 32 and 36 of the carriage 11, so that the device places the sheets 3 on the separate stack according to their properties 1 can sort. On the feed path 37, the testing device 29 analyzes the sheet 3 (FIG. 1) and forwards to the control device 31 a predetermined stack signal corresponding to the printed image or the size of the sheet 3. The control device 31 is set up to receive the stack signal and to control the drive 30 as a function of the stack signals. Before the sheet 3 reaches the entry level 27 or 28, the drive 30 moves the carriage 11 into the predetermined starting position, so that the sheet 3 is deposited on the predetermined stack 1 after being gripped by the belts 17, 26.

Der Wagen 11 ist in die Startposition über dem einen Stapel 1 gefahren und wartet dort die Ankunft des Blatts 3 in der Eingangsebene 27 ab, das auf den anderen Stapel 1 abzulegen ist. Sobald der nicht gezeigte Fühler in der Eingangsebene 27 die Vorderkante des Blatts 3 ertastet, beschleunigt der Wagen 11 in die Bewegungsrichtung 32. In der Figur 6 hat das von den Bändern 17, 26 erfasste Blatt 3 den Wagen 11 eingeholt und wird um die Führungsrolle 13 herum auf den zweiten Stapel 1 umgekehrt abgelegt.The carriage 11 has moved into the starting position above the one stack 1 and is waiting there for the arrival of the sheet 3 in the entrance level 27, which is to be deposited on the other stack 1. As soon as the sensor (not shown) senses the front edge of the sheet 3 in the input plane 27, the carriage 11 accelerates in the direction of movement 32. In FIG Bands 17, 26, sheet 3 caught the carriage 11 and is placed around the guide roller 13 on the second stack 1 in reverse.

Damit die Blätter 3 von beiden Eingangsebenen 27 und 28 her problemlos gestapelt werden können, weisen nach der Figur 7 beide Führungsrollen 13 und 15 die Ablenker 34 auf. Ein zwischen den beiden Ablenkern 34 unmittelbar über der Stapelebene 5 auf dem Wagen 11 angeordnetes Schutzblech 47 verhindert vorteilhaft einen Kontakt des über die mittlere Führungsrolle 14 gespannten Endlosbands 26 mit dem obersten Blatt 3 des Stapels 1. Das Schutzblech 47 ist auf den äusseren Führungsrollen 13 und 15 zugewandten Seiten von der Stapelfläche 5 weggebogen, damit sich kein Blatt 3 am Schutzblech 47 verfangen kann. Seine Wölbung kann gleichmässig sein, wobei zwischen den Ablenkern 34 das Schutzblech 47 in einem vorbestimmten Abstand dem über die mittlere Führungsrolle 14 gespannten Endlosband 26 folgt. Das Schutzblech 47 und die Ablenker 34 können miteinander verbunden sein und eine Einheit bilden.So that the sheets 3 can be stacked easily from both entrance levels 27 and 28, according to FIG. 7 both guide rollers 13 and 15 have the deflectors 34. A fender 47 arranged between the two deflectors 34 directly above the stacking level 5 on the carriage 11 advantageously prevents contact of the endless belt 26 stretched over the middle guide roller 14 with the uppermost sheet 3 of the stack 1. The fender 47 is on the outer guide rollers 13 and 15 facing sides bent away from the stacking surface 5 so that no sheet 3 can get caught on the mudguard 47. Its curvature can be uniform, the protective plate 47 between the deflectors 34 following the endless belt 26 stretched over the central guide roller 14 at a predetermined distance. The fender 47 and the deflectors 34 can be connected to one another and form a unit.

Die hier gezeigten Ausführungen können vom Fachmann im Rahmen des durch die Ansprüche bewirkten Schutzbereiches kombiniert werden.The embodiments shown here can be combined by a person skilled in the art within the scope of the protection provided by the claims.
