Description

Die Erfindung betrifft einen Bogenanleger zum Vereinzeln von Bogen mit einem ersten und einem zweiten Bogentrenner, die jeweils einen Trennsauger aufnehmenden Trennsaugerträger und einen Transportsauger aufnehmenden Transportsaugerträger sowie eine zugeordnete Bogentrennerhöhenverstellung aufweisen, wobei die Bogentrenner gemeinsam zur Formatanpassung in oder entgegen der Transportrichtung der Bogen verschiebbar sind.The invention relates to a sheet feeder for separating sheets with a first and a second sheet separator, each having a separating sucker receiving Trennsaugerträger and a transport suction receiving Transportportsaugerträger and an associated Bogentrennerhöhenverstellung, the sheet separators are jointly displaceable for format adaptation in or against the transport direction of the bow.

In Bogenanlegern ist üblicherweise ein Trennsauger und Transportsauger aufweisender Bogentrenner vorgesehen. Der Antrieb der Trennsauger und der Transportsauger erfolgt mit Hilfe von Kurvenkoppelgetrieben. Dabei wird einem die Trennsauger aufnehmenden Trennsaugerträger eine zyklische Bewegung zwischen einer oberen und einer unteren Rastposition aufgeprägt. In der unteren Rastposition wird von den Trennsaugern der jeweils oberste Bogen eines Bogenstapels erfasst und durch die nachfolgende Bewegung in die obere Rastposition vereinzelt. In einer Übergabeposition wird der vereinzelte Bogen an die Transportsauger übergeben, die vorzugsweise eine translatorische Bewegung ausführen und den von den Transportsaugern vereinzelten Bogen zur dem Bogenanleger nachgeordneten bogenverarbeitenden Maschine transportieren.In sheet feeders usually a vacuum cleaner and transport suction exhibiting sheet separator is provided. The separation sucker and the transport suction device are driven by means of cam coupling gears. In this case, the separating sucker receiving Trennsaugerträger a cyclic movement between an upper and a lower detent position is impressed. In the lower detent position, the respective uppermost arc of a sheet stack is detected by the separating suckers and separated by the subsequent movement into the upper detent position. In a transfer position of the isolated sheet is transferred to the transport suction, which preferably perform a translational movement and transport the separated from the transport suction sheets to the sheet feeder downstream sheet processing machine.

Zur Realisierung der Bogentrennung und des Bogentransports sind Blasluftdüsen vorgesehen. Außerdem ist dem Bogentrenner eine Höhenstelleinrichtung zugeordnet.
Bei großformatigen Bogenanlegern ist es bekannt, in der Formatbreite zwei Bogentrenner nebeneinander anzuordnen sowie die Antriebe dieser Bogentrenner mechanisch zu koppeln und als funktionelle Einheit zu betreiben, wobei eine Höhenstelleinrichtung vorgesehen ist, die, initiiert durch eine Stapelabtastung, das Höhenniveau dieser Einheit beeinflusst.
To realize the sheet separation and the sheet transport blowing air nozzles are provided. In addition, the sheet separator is assigned a height adjustment device.
In the case of large-format sheet feeders, it is known to juxtapose two sheet separators in the format width and to mechanically couple the drives of these sheet separators and to operate them as a functional unit, wherein a height setting device is provided which, initiated by a stack scan, influences the height level of this unit.

Derartige Bogenanleger haben den Nachteil, dass aufgrund der starren Kopplung der Bogentrenner der Formatstellbereich des Bogenanlegers eingeschränkt ist. Außerdem ist es nicht möglich, die einzelnen Bogentrenner unabhängig voneinander einzustellen und damit an das zur Verarbeitung gelangende Verarbeitungsgut sowie an die Form der Bogenstapel anzupassen, so dass diese Bogenanleger nur beschränkt einsetzbar sind.Such sheet feeder have the disadvantage that due to the rigid coupling of the sheet separator of the format adjustment range of the sheet feeder is limited.
