Abstract
Description
Die Neuerung betrifft einen Anlegetisch zur Anlage von Bogen an eine bogenverarbeitenden Maschine, insbesondere eine Druckmaschine, dem Bogen von einem Bogenanleger in einer etwa horizontalen Zuführebene zuführbar sind und der gegenüber der Zuführebene geneigt ist, wobei etwa über dem Bereich der Knickstelle zwischen Zuführebene und Anlegetisch eine Umlenkrolle angeordnet ist, durch die Bogen aus der Zuführebene in die Ebene des Anlegetischs umlenkbar sind.The innovation concerns a feed table for the application of sheets to one sheet processing machine, especially a printing machine, the sheet can be fed from a sheet feeder in an approximately horizontal feed plane and which is inclined with respect to the feed plane, being approximately over the area a deflection roller at the kink between the feed level and the feed table is arranged through the sheet from the feed plane into the plane of the Feed tables are deflectable.
Es ist bekannt über einen derartigen Anlegetisch zum umlenken der zu fördernden Bogen ein Umlenkrollenpaar zu verwenden, das in Förderrichtung hintereinander an einem gemeinsamen Träger angeordnete Einzelumlenkrollen aufweist. Bei dieser Anordnung wird die in Förderrichtung hintere Einzelumlenkrolle von der in Förderrichtung vorderen Einzelumlenkrolle drehbar angetrieben. Außerdem ist das Umlenkrollenpaar in einer festen Position zum Anlegetisch fixiert. Dies erfordert bei einem Wechsel der Qualität und Art der zu verarbeitenden Bogen einen Umbau, um das Umlenkrollenpaar den jeweiligen Verhältnissen anzupassen. Außerdem ist die Vorrichtung durch den Antrieb der Umlenkrollen aufwendig und weist einen zu kurzen Umlenkbereich auf, der lediglich durch zwei Umlenkpunkte gebildet wird.It is known about such a feed table for deflecting the conveying bow to use a pair of deflection rollers, which is in the conveying direction Individual deflection rollers arranged one behind the other on a common support having. With this arrangement, the rear one in the conveying direction Single pulley can be rotated from the front single pulley in the conveying direction driven. In addition, the pair of guide rollers is in a fixed position for Fixed table. This requires a change in the quality and type of processing bow a conversion to the respective pair of pulleys Adapt conditions. In addition, the device is powered by the Deflecting rollers complex and has a too short deflection area, the is only formed by two deflection points.
Weiterhin ist es aus der DE-U-29704796 bekannt, ein derartiges Umlenkrollenpaar mittels eines pneumatischen Zylinders mit einstellbarer Kraft gegen den Anlegetisch anstellbar zu machen. Dabei wird der ankommende Bogen zwar sicher umgelenkt, kann aber durch die kraftschlüssige Beaufschlagung verzogen werden. Daher besteht die Gefahr, daß ein derartiger Bogen nicht richtig zur bogenverarbeitenden Maschine zugeführt werden kann. Furthermore, it is known from DE-U-29704796, such Pair of deflection pulleys using a pneumatic cylinder with adjustable force to make it adjustable against the feed table. In doing so, the incoming bow redirected safely, but can be done by the force-fitting action be warped. Therefore, there is a risk that such an arch will not can be fed correctly to the sheet-processing machine.
Aufgabe der Neuerung ist es daher einen Anlegetisch der eingangs genannten Art zu schaffen, der ohne Kraftbeaufschlagung zur Verarbeitung der verschiedenartigsten Bogen, insbesondere auch für Bogen hoher Steifigkeit geeignet ist und alle Bogen sicher sowohl umlenkt als auch dem Anlegetisch zum exakten Weitertransport zuführt.The task of the innovation is therefore a feed table of the type mentioned To create the kind of processing without the application of force a wide variety of arches, especially for arches with high rigidity is suitable and safely deflects all bends as well as the feed table to exact further transport.
Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß mehrere Umlenkrollen
vorgesehen sind. Die Umlenkrollen sind dabei senkrecht zur Ebene des
Anlegetischs beabstandet und einstellbar und in Form einer Kurve etwa tangential
gegen die Ebene des Anlegetischs auslaufend angeordnet. Durch diese
Ausbildung ist nicht nur eine selbsttätige Anpassung des Abstandes der
Umlenkrolle zum Anlegetisch bei entsprechender Einstellung auf das zu
verarbeitende Material, sondern auch eine Variation des Umlenkweges der
Umlenkrolle auf den Anlegetisch abhängig von der jeweiligen Steifigkeit der
Bogen möglich.
Vorzugsweise sind die in der Anordnung verwendeten Umlenkrollen frei drehbar
gelagert, so daß es durch eine Umlenkrolle nicht zu Schleifspuren auf den Bogen
kommen kann.
Eine einfache Ausbildung wird dadurch erreicht, daß die Umlenkrolle als relativ
schmale Umlenkräder ausgebildet sind und an dem freien Ende eines in der Höhe
einstellbaren Halters angeordnet ist.According to the innovation, this object is achieved in that several deflection rollers are provided. The deflection rollers are spaced perpendicularly to the plane of the feed table and can be adjusted and are arranged in the form of a curve that runs approximately tangentially against the plane of the feed table. With this design, not only an automatic adjustment of the distance of the deflection roller to the feed table with appropriate adjustment to the material to be processed, but also a variation of the deflection path of the deflection roller on the feed table is possible depending on the respective stiffness of the sheet.
Preferably, the deflection rollers used in the arrangement are freely rotatable, so that there can be no traces of grinding on the sheet by a deflection roller.
A simple design is achieved in that the deflection roller is designed as a relatively narrow deflection wheel and is arranged on the free end of a holder which is adjustable in height.
Eine Führung der Bogen über einen längeren Streckenabschnitt wird erreicht und
ein Hochwippen des hinteren Endes des Bogens weitgehend vermieden, wenn
die Umlenkräder zu mehreren in Förderrichtung hintereinander angeordnet sind,
wobei vorzugsweise alle Umlenkräder frei drehbar gelagert sind.
Sind die Umlenkräder in einem Abstand zueinander angeordnet und wechselseitig
an dem Halter als gemeinsamen Träger drehbar gelagert, wobei die Konturen der
Umlenkräder einander überlappen, kann damit eine sichere Anlage jedes Bogens
an allen Umlenkrädem gewährleistet werden, so daß jeder Bogen sicher auf dem
Anlegetisch bzw. auf ein über den Anlegetisch geführtes Förderband geführt wird.
Zum sicheren Umlenken der Bogen dient es, wenn quer zur Förderrichtung im
Abstand nebeneinander mehrere Halter mit Umlenkrädem angeordnet sind.A guiding of the sheets over a longer section is achieved and a rocking of the rear end of the sheet is largely avoided if the deflection wheels are arranged one behind the other in the conveying direction, preferably all deflection wheels being freely rotatable.
If the deflection wheels are arranged at a distance from one another and are mutually rotatably mounted on the holder as a common carrier, the contours of the deflection wheels overlapping one another, a secure contact of each sheet on all deflection wheels can thus be ensured, so that each sheet is securely placed on the feed table or on a conveyor belt guided over the feed table. For safe deflection of the sheets, it is used if several holders with deflection wheels are arranged next to one another transversely to the conveying direction.
Ein Ausführungsbeispiel der Neuerung ist in der einzigen Figur der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the innovation is in the single figure of the drawing shown and is described in more detail below.
Der in der Figur dargestellte Anlegetisch besitzt eine Tischoberfläche 1, an deren
in Förderrichtung 2 gerichteten Enden Bänderwalzen 3 angeordnet sind, über die
endlose Förderbänder 4 geführt sind. Die Förderbänder 4 sind durch eine der
Bänderwalzen 3 antreibbar und transportieren Bogen in Förderrichtung 2 zu einer
Druckmaschine.
Die Bogen B am höher liegenden Ende des geneigt angeordneten Anlegetischs
werden etwa horizontal oberhalb der eine Zuführebene 5 bildenden Oberfläche
von einem Bogenstapel eines Bogenanlegers zugeführt. An der Zufuhrseite
können kippbare Anschläge 6 vorgesehen sein, die hier nur angedeutet sind.
Diese Anschläge 6 geben den Bogenweg vom Bogenstapel zur Bänderwalze 3
frei. Die Vorwärtsbewegung des Bogens zum Anlegetisch wird durch hier nicht
gezeigte, auf die Bänderwalze taktweise anstellbare Förderrollen bewirkt.
Der Bogen B wird zwischen der Bänderwalze 3 und den Förderrollen eingeklemmt
und durch die Drehung der Bänderwalze 3 vorwärts bewegt. Die Förderrollen
wirken aber nur punktuell an der Bänderwalze 3.The feed table shown in the figure has a table surface 1, at the ends of which are arranged in the direction of
The sheets B at the higher end of the inclined feed table are fed approximately horizontally above the surface forming a
In anderen Ausführungsformen kann eine zusätzliche Förderwalze der
Bänderwalze 3 vorgeordnet sein. Dann wirken die Förderrollen mit dieser
Förderwalze zusammen. Die Bogen B werden dann am höher liegenden Ende des
geneigt angeordneten Anlegetischs von dem Bogenanleger über eine
Überbrückungsebene der Bänderwalze 3 zugeführt. Die Überbrückungsebene
bildet dann die Zuführebene 5, die in der Erfindung von Bedeutung ist. In other embodiments, an additional conveyor roller can
Im Bereich der Knickstelle 7 über dem zufuhrseitigen Ende des Anlegetischs ist
über dem Anlegetisch vertikal verstellbar jedem Förderband 4 zugeordnet eine
Anordnung von Überleitrollen 8 angeordnet. Die Überleitrollen 8 bestehen aus
einem gemeinsamen Träger 10, der an einer höhenverstellbaren Halterung 11
befestigt ist. Die Überleitrollen 8 weisen weiterhin eine Reihe von Umlenkrädem 9
auf, die am Träger 10 wechselseitig angebracht sind. Der Achsabstand der
Umlenkräder 9 ist so gewählt, daß die Konturen der Umlenkräder 9 sich etwas
überdecken. Dadurch entsteht an der Unterseite der Überleitrollen 8 eine quasi
kontinuierliche Leitfläche. Die Umlenkräder 9 sind an dem Träger 10 in Richtung
der Verbindung ihrer Drehachsen in etwa bogenförmig angeordnet. Damit wird
erreicht, daß die Leitfläche der Überleitrollen 8 einlaufseitig in etwa tangential zur
Förderebene vom Anleger her und auslaufseitig in etwa tangential zur
Tischoberfläche 1 des Anlegetisches ausgerichtet ist. Der Übergang aus der
Horizontalen in die Förderebene des Anlegetisches ist durch die Anordnung der
Überleitrollen 8 gekrümmt.In the area of the
Die Leitwirkung der Überleitrollen 8 ist aus der Zeichnung entnehmbar. Es ist
erkennbar, daß der Bogen B von den Überleitrollen 8 aus der Horizontalen in eine
schräge Förderrichtung gekrümmt wird. Dabei legt der Bogen B sich auf die
Förderbänder 4 auf. In bevorzugter Ausführungsform sind dies mit von deren
Unterseite mit Saugluft beaufschlagte Saugbänder, die den Bogen bei Berührung
mit einer kleinen Fläche schon erfassen und festhalten.The conductivity of the transfer rollers 8 can be seen from the drawing. It is
recognizable that the sheet B from the transfer rollers 8 from the horizontal to a
oblique conveying direction is curved. The sheet B lies on the
Die Darstellung der Lage des zu führenden Bogens aus der Figur kann auch für die weiter oben beschriebene Ausführungsform mit vorgelagerter Förderwalze angenommen werden. Dabei werden auch steifere Bögen sicher umgelenkt und so auf die Saugbänder geleitet, daß diese die Bögen erfassen können. The representation of the position of the sheet to be guided from the figure can also for the embodiment described above with an upstream conveyor roller be accepted. Stiffer bends are also deflected safely so directed to the suction tapes that they can grasp the sheets.
Bei der Ausführungsform mit direkt auf der Bänderwalze 3 arbeitenden
Förderrollen werden die Überleitrollen 8 näher an die Oberfläche des
Anlegetisches eingestellt. Dann setzt die Leitwirkung der Überleitrollen 8 im
wesentlichen direkt nach dem Austreten des Bogens B zwischen den Förderrollen
und der Bänderwalze 3 ein. In the embodiment with working directly on the
