Es ist vorteilhaft, wenn die Einlauf-Fördereinheit mindestens einen Einlauf-Saugriemen aufweist, wobei der Einlauf-Saugriemen mittels eines Vakuums den Bogen ansaugt. Denn so kann der Bogen schonend zur Übergabe transportiert werden.It is advantageous if the infeed conveyor unit has at least one infeed suction belt, the infeed suction belt sucking in the sheet by means of a vacuum. This is because the sheet can be gently transported to the handover.
Ferner ist es vorteilhaft, wenn die Einlauf-Fördereinheit ein Mittel zur Unterbrechung des Vakuums des Einlauf-Saugriemens aufweist, wobei der Bogen von der Einlauf-Transportseite für die Übergabe freigeben wird. Denn so kann der Bogen für die Übergabe schonend freigegeben werden.It is also advantageous if the infeed conveyor unit has a means for interrupting the vacuum of the infeed suction belt, the sheet being released from the infeed transport side for transfer. In this way, the sheet can be gently released for transfer.
Ferner ist es vorteilhaft, wenn der Einlauf-Saugriemen von einer Saugleiste abhebbar ist, wobei das Vakuum unterbrochen wird, und wobei der Bogen von der Einlauf-Transportseite für die Übergabe freigeben wird. Damit kann ohne eine Abschaltung des Vakuums bzw. einer das Vakuum erzeugenden Saugeinrichtung der Bogen freigegeben werden.It is also advantageous if the infeed suction belt can be lifted off a squeegee, the vacuum being interrupted and the sheet being released for the transfer from the infeed transport side. The sheet can thus be released without switching off the vacuum or a suction device generating the vacuum.
Vorteilhaft ist es, wenn die Einlauf-Fördereinheit eine Exzentereinheit aufweist, wobei die Exzentereinheit den Einlauf-Saugriemen von der Saugleiste abheben und senken kann.

Because that's how the vacuum breaks Infeed suction belt together and the sheet is gently released for transfer and transferred to the outfeed conveyor unit.
Und es ist vorteilhaft, wenn das Unterbrechen des Vakuums in der Einlauf-Fördereinheit ein Abheben des Einlauf-Saugriemens von einer Vakuumleiste aufweist.

Die Einlauf-Transportseite 7 wird beispielsweise gebildet durch eine Förderfläche des Einlauf-Saugriemens 10 oder durch eine durch Kombination von Förderflächen mehrerer Einlauf-Saugriemen. Die Auslauf-Transportseite 7 wird beispielsweise gebildet durch eine Förderfläche des Auslauf-Saugriemens 11 oder durch eine durch Kombination von Förderflächen mehrerer Auslauf-Saugriemen. Der Übergabebereich 9 ist zwischen der Einlauf-Transportseite 7 und der Auslauf-Transportseite 8 angeordnet. Beispielsweise ist eine Höhe des Übergabebereichs definiert durch einen Abstand zwischen der Einlauf-Transportseite 7 und der Auslauf-Transportseite 8 und beträgt 10mm. Die Einlauf-Transportseite 7 ist der Auslauf-Transportseite 8 flächig zugewandt angeordnet, so dass der Bogen 4 bei einem Transport zur Übergabe entlang der Einlauf-Transportseite 7 zu dem Übergabebereich 9 hingeführt wird und nach der Übergabe entlang der Auslauf-Transportseite 8 weggeführt wird.The
Der mindestens eine Einlauf-Saugriemen 10 ist derart ausgelegt, dass dieser mittels eines Vakuums den Bogen 4 ansaugen kann. Der Bogen 4 ist beispielsweise ein Bogen Papier, ein Kuvert, ein Blech oder ein anderes flaches Gut.The at least one
Zur Übergabe des Bogens 4 wird dieser aus der Einlauf-Richtung 5 kommende Bogen 4 mittels der Einlauf-Fördereinheit 2 und des Einlauf-Saugriemens 10 transportiert. Der Einlauf-Saugriemen 10 saugt mittels eines Vakuums den Bogen 4 an und bewegt den Bogen 4 an der Einlauf-Transportseite 7 entlang in den Übergabebereich 9. Zur Übergabe wird das Vakuum unterbrochen, wenn der Bogen 4 in dem Übergabebereich 9 ist. Die Einlauf-Fördereinheit 2 gibt somit den Bogen 4 frei.For the transfer of the sheet 4, this sheet 4 coming from the
Das Vakuums wird beispielsweise dadurch gesteuert, dass ein Sensor eine bestimmte Position des Bogens 4 in dem Übergabebereich 9 erkennt und in diesem Fall eine Unterbrechung des Vakuums auslöst, indem ein Signal zur Steuerung der Einlauf-Fördereinheit 2 bereitgestellt wird. Beispielsweise ist ein Sensor ein optischer Sensor oder einer Lichtschranke.The vacuum is controlled, for example, in that a sensor detects a certain position of the sheet 4 in the
Beispielsweise steuert eine Steuereinheit die Einlauf-Fördereinheit 2, den Einlauf-Saugriemen 10 und das Vakuum. Die Steuereinheit verarbeitet das Signal zur Steuerung dahingehend, dass bei Bereitstellung des Signals die Einlauf-Fördereinheit 2 angehalten und das Vakuum bzw. eine das Vakuum erzeugende Saugeinrichtung abgeschaltet wird, so dass der Transport des Bogens 4 stoppt und der Bogen 4 zur Übergabe freigegeben wird.For example, a control unit controls the
Beispielsweise steuert die Steuereinheit nach einer kurzen Zeitspanne zur Übergabe ein Weiterfahren der Fördereinheit 2 und ein Anschalten des Vakuums, so dass weitere Bögen transportiert und übergeben werden können.For example, after a short period of time for the transfer, the control unit controls a further movement of the
Der von der Einlauf-Fördereinheit 2 losgelassene Bogen 4 wird von dem Auslauf-Saugriemen 11 auf der Auslauf-Transportseite 8 mittels eines Vakuums angesaugt. Die Auslauf-Fördereinheit 3 transportiert den von dem Auslauf-Saugriemen 11 festgehaltenen Bogen 4 in der Auslauf-Richtung 6 entlang der Auslauf-Transportseite 8 weiter. Somit wird der Bogen 4 aus der Einlauf-Richtung 5 in die Auslauf-Richtung 6 umgelenkt. Beispielsweise ist ein Umlenkwinkel, der zwischen der Einlauf-Richtung 5 und der Auslauf-Richtung 6 definiert wird, ca. 90°, so dass der Bogen 4 eine rechtwinklige Richtungsänderung erfährt. Ist beispielsweise der Bogen 4 ein Papierbogen kann der Papierbogen im Hochformat in die Vorrichtung 1 einlaufen und im Querformat aus der Vorrichtung 1 auslaufen; die Vorrichtung 1 ändert so eine Richtung eines Papierstroms, der einen Strom aus Papierblättern umfasst.The sheet 4 released by the
Der Einlauf-Saugriemen 10 ist von der Saugleiste 13 abhebbar. Wird beispielsweise vom Sensor zur Steuerung der Einlauf-Fördereinheit 2 das Signal einer Erkennung des Bogens 4 bereitgestellt, wird der Einlauf-Saugriemen 10 gestoppt und/oder von der Saugleiste 13 abgehoben und das Vakuum unterbrochen, so dass der Bogen 4 freigegeben wird. Zudem kann durch ein Abheben des Einlauf-Saugriemens 10 in Richtung der Auslauf-Transportseite 8 der Bogen 4 zur Übergabe an den Auslauf-Saugriemen 11 bewegt werden.The
Die Exzentereinheit 12 ist mit der Saugleiste 13 verbunden, so dass die Exzentereinheit 12 den Einlauf-Saugriemen 10 von der Saugleiste 13 abheben und/oder senken kann.The
In einer weiteren Ausführungsform einer erfindungsgemäßen Vorrichtung kann die Vorrichtung als Weiche eingesetzt werden, indem beispielsweise eine Steuerung eines Bewegens des Einlauf-Saugriemens 10 von der Saugleiste 13 für Bögen unterschiedlich durchgeführt wird, so dass ein erster Bogen aus der Einlauf-Richtung 5 in die Auslauf-Richtung 6 umgelenkt wird, und ein zweiter Bogen nicht in die Auslauf-Richtung 6 umgelenkt wird, sondern durch die Einlauf-Fördereinheit 2 mit Einlauf-Saugriemens 10 transportiert wird und in der Einlauf-Richtung 5 die Vorrichtung passiert.In a further embodiment of a device according to the invention, the device can be used as a switch, for example by controlling a movement of the
In Ausführungsformen einer erfindungsgemäßen Vorrichtung kann ein Umlenkwinkel, der zwischen der Einlauf-Richtung 5 und der Auslauf-Richtung 6 definiert wird, ca. 0°, ca. 90°, ca. 180°, oder ca. 270°, so dass bei 0° ein Durchlauf ohne Richtungsänderung, ein Umlenken um 90° oder 270° oder bei 180° ein Rücklauf des Bogens 4 stattfindet.In embodiments of a device according to the invention, a deflection angle that is defined between the
Im ersten Verfahrensschritt 21 erfolgt ein Festhalten des Bogens 4 durch die Einlauf-Fördereinheit 2 an der Einlauf-Transportseite 7 der Einlauf-Fördereinheit 2. Beispielsweise wird der Bogen 4 durch die Einlauf-Fördereinheit 2 mittels eines Ansaugens mit mindestens den Einlauf-Saugriemen 10 durchgeführt und das Ansaugen wird mittels eines Vakuums erzeugt.In the
Im zweiten Verfahrensschritt 22 wird der Bogen 4 in der Einlauf-Richtung 5 entlang der Einlauf-Transportseite 7 in den Übergabebereich 9 transportiert. Beispielsweise fördert die Einlauf-Fördereinheit 2 den angesaugten Bogen 4 mit den Einlauf-Saugriemen 10.In the
Im dritten Verfahrensschritt 23 wird der Bogen 4 durch die Einlauf-Fördereinheit 2 in dem Übergabebereich 9 losgelassen. Beispielsweise wird mittels Sensorik erkannt, dass der Bogen 4 an einer festgelegten Position im Übergabebereich 9 ist, und mittels Steuerung das Loslassen des Bogens durch die Einlauf-Fördereinheit 2 in dem Übergabebereich 9 durch ein Abheben des Einlauf-Saugriemens 10 von der Vakuumleiste 13 durchgeführt.In the
Im vierten Verfahrensschritt 24 wird der Bogen 4 durch die Auslauf-Fördereinheit 3 in dem Übergabebereich 9 angenommen und der Bogens 4 an der Auslauf-Transportseite 8 der Auslauf-Fördereinheit 3 festgehalten. Beispielsweise saugt der mindestens eine Auslauf-Saugriemen 11 den Bogen 4 an.In the
Das Übergeben des Bogens 4 von der Einlauf-Fördereinheit 2 an die Auslauf-Fördereinheit 3 findet in den dritten Verfahrensschritt 23 und vierten Verfahrensschritt 24 statt, wobei der Bogen 4 im dritten Verfahrensschritte 23 im Übergabebereich 9 an der Einlauf-Transportseite 7 freigeben wird, und die Einlauf-Transportseite 7 der Auslauf-Transportseite 8 flächig zugewandt angeordnet ist. Im vierten Verfahrensschritt 24 kann somit der Bogen 4 an der Auslauf-Transportseite 8 im Übergabebereich 9 angenommen und festgehalten werden.The transfer of the sheet 4 from the
Im fünften Verfahrensschritt wird der Bogen 4 in der Auslauf-Richtung 6 entlang der Auslauf-Transportseite 8 transportiert. Beispielsweise fördert die Auslauf-Fördereinheit 3 den angesaugten Bogen 4 mit den Auslauf-Saugriemen 11 weiter.In the fifth method step, the sheet 4 is transported in the
