Description
Die vorliegende Erfindung bezieht sich auf eine Auslegevorrichtung einer bogenverarbeitenden Maschine, insbesondere Druckmaschine gemäß dem Oberbegriff von Patentanspruch 1.The present invention relates to a delivery device of a sheet-processing machine, in particular printing machine according to the preamble of
Derartige Auslegevorrichtungen dienen dem Aussondem von beim Anfahren der Druckmaschine oder beim Fortdruck anfallenden Makulaturbogen. Sie ermöglichen außerdem das Bedrucken von Bogen im Non-Stop-Betrieb, indem die während des Wechsels des Auslegerstapels anfallenden bedruckten Bogen einem anderen Stapelsystem als dem Auslegerstapel zugeführt werden.Such Auslegevorrichtungen serve the Aussondem incurred when starting the printing press or during production waste sheet. They also enable non-stop sheet printing by feeding the printed sheets produced during the change of the delivery stack to a stacking system other than the delivery stack.
Die aus der US 2 406 936 bekannte Auslegevorrichtung umfasst ein Kettenfördersystem, das bedruckte Bogen wahlweise auf einem Hauptstapel oder einem vor dem Hauptstapel unterhalb des Kettenfördersystems angeordneten Hilfsstapel ablegt. Die Bogen werden an ihren Vorderkanten von Greifern, die Bestandteil des Kettenfördersystems sind, fixiert. Im Bereich des unteren Trums der Ketten ist eine Greifersteuerkurve beweglich gelagert, mit der die Bewegung der Greifer steuerbar ist. Sollen Bogen auf dem Hilfsstapel abgelegt werden, wird die Greifersteuerkurve in Bezug auf die Kettenbahn bewegt, bis sie auf die Greifer einwirkt und diese den jeweiligen Bogen über dem Hilfsstapel freigeben. Die freigegebenen Bogen sinken unter der Wirkung der Schwerkraft auf den Hilfsstapel.
Die Auslegevorrichtung eignet sich nicht zur Verwendung in schnelllaufenden Druckmaschinen, da sich die bedruckten Bogen nach ihrer Freigabe nur langsam zum Hilfsstapel bewegen und die Gefahr der Kollision mit nachfolgenden Bogen besteht.The delivery device known from US Pat. No. 2,406,936 comprises a chain conveyor system which deposits printed sheets optionally on a main stack or an auxiliary stack arranged in front of the main stack below the chain conveyor system. The sheets are fixed at their leading edges by grippers, which are part of the chain conveyor system. In the area of the lower run of the chains a gripper control cam is movably mounted, with which the movement of the gripper is controllable. If sheets are to be deposited on the auxiliary pile, the gripper control cam is moved with respect to the warp sheet until it acts on the grippers and they release the respective sheet over the auxiliary pile. The released bows sink under the effect of gravity on the auxiliary pile.
The delivery device is not suitable for use in high-speed printing machines, since the printed sheets move only slowly after release to the auxiliary stack and there is a risk of collision with subsequent sheets.
Aus der DE 24 30 212 A1 ist eine Auslegevorrichtung bekannt, die eine Sortiereinrichtung aufweist, welche die bedruckten Bogen wahlweise auf zwei Auslegerstapel ablegt. Ein umlaufender erster Kettenförderer führt die Bogen einem ersten Auslegerstapel zu. Dem ersten Kettenförderer ist eine Entnahmetrommel mit Greifersystemen zugeordnet, der ein zweiter Kettenförderer nachgeordnet ist, mit welchem Bogen zu einem zweiten Auslegerstapel zuführbar sind. Abhängig von ihrer Qualität werden die Bogen dem ersten oder dem zweiten Auslegerstapel zugeführt.
Die Auslegevorrichtung gemäß der DE 198 19 491 C1 weist ein endlos umlaufendes, die bedruckten Bogen einem ersten Auslegerstapel zuführendes Bogenfördersystem und eine in Förderrichtung vor dem ersten Auslegerstapel als Weiche wirkende Trommel zur wahlweisen Bogenentnahme auf. Mit der Trommel sind entnommene Bogen auf ein zweites, unterhalb der Trommel angeordnetes Bogenfördersystem ablegbar, das die Bogen einem zweiten Stapelsystem zuführt.From DE 24 30 212 A1 discloses a delivery device is known which has a sorting device which stores the printed sheet either on two delivery pile. A revolving first chain conveyor feeds the sheets to a first delivery pile. The first chain conveyor is associated with a removal drum with gripper systems, which is followed by a second chain conveyor, with which sheet can be fed to a second delivery stack. Depending on their quality, the sheets are fed to the first or the second delivery pile.
The delivery device according to DE 198 19 491 C1 has an endlessly circulating sheet feed system feeding the printed sheets to a first delivery stack and a drum for optional sheet removal acting in the conveying direction before the first delivery stack as a switch. With the drum are drawn sheets on a second, can be deposited below the drum arranged sheet conveying system that feeds the sheets to a second stacking system.
Nachteilig an den Auslegevorrichtungen, in denen die Bogen mit Trommeln entnommen werden, ist der große maschinenbauliche Aufwand. Die Bewegung der Trommel muss an die Bewegung der umlaufenden Fördersysteme angepasst werden. Zudem sind zur Führung der Bogen nach der Trommel zusätzliche Bogenleiteinrichtungen oder weitere Bogenfördersysteme erforderlich, um die in einem Umfangsbereich der Trommeln auf einer halbkreisförmigen Bahn geführten Bogen störungsfrei auf dem Hilfsstapel abzulegen.A disadvantage of the delivery devices, in which the sheets are taken with drums, is the great mechanical engineering effort. The movement of the drum must be adapted to the movement of the circulating conveyor systems. In addition, for guiding the sheet to the drum additional sheet guiding or other sheet conveying systems are required to store the guided in a peripheral region of the drums on a semicircular sheet trouble-free on the auxiliary stack.
Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung der vorgenannten Nachteile eine Auslegevorrichtung einer bogenverarbeitenden Maschine, insbesondere Druckmaschine zu schaffen, die einfach aufgebaut ist und eine verbesserte Funktionssicherheit insbesondere bei der Ablage von mit großer Geschwindigkeit zugeführten Bogen aufweist.The invention has for its object to provide while avoiding the aforementioned disadvantages, a delivery device of a sheet-processing machine, in particular printing press, which is simple in construction and has improved reliability, especially in the storage of supplied at high speed bow.
Erfindungsgemäß wird diese Aufgabe mit einer Auslegevorrichtung der eingangs genannten Art gelöst, die die Merkmale des Patentanspruchs 1 aufweist.According to the invention this object is achieved with a delivery device of the type mentioned, having the features of
Der Vorteil der erfindungsgemäßen Auslegevorrichtung besteht darin, dass die von dem Bogenfördersystem freigegebenen Bogen von dem Saugband in Art einer Zwangsführung bis zu der Bogenaufnahmeeinrichtung geführt werden und die Ablage der Bogen damit weitgehend unabhängig von der Beschaffenheit der Bogen, insbesondere von deren Biegesteifigkeit und Flächengewicht, erfolgt. Damit können auch bei großen Verarbeitungsgeschwindigkeiten Bogen ausreichend schnell von dem umlaufenden Bogenfördersystem abgeführt werden, um Kollisionen zu vermeiden.
In der ersten Betriebsstellung unterstützt das von der Bogenleiteinrichtung umfasste Saugband die Bogenführung, indem es als Bogenleitfläche wirkt und das Auftreten von Relativbewegungen verhindert. Abschmiererscheinungen an im Schön- und Widerdruck bedruckten Bogen können damit weitestgehend vermieden werden. Vorzugsweise ist die Bogenleiteinrichtung als Kammer ausgebildet, in der ein Unterdruck erzeugbar ist. Die Kammer weist auf der dem Bogenförderweg zugewandten Seite Öffnungen auf, über die das Saugband läuft.The advantage of the delivery device according to the invention is that the released from the sheet conveying system sheets are guided by the suction belt in the manner of positive guidance up to the sheet receiving device and the filing of the sheet thus largely independent of the nature of the sheet, in particular their flexural rigidity and basis weight occurs , Thus, even at high processing speeds, sheets can be removed sufficiently quickly from the circulating sheet conveying system in order to avoid collisions.
In the first operating position, the suction belt encompassed by the sheet guiding device assists sheet guiding by acting as a sheet guiding surface and preventing the occurrence of relative movements. Greasing on printed in perfecting bow can thus be largely avoided. Preferably, the sheet guiding device is designed as a chamber in which a negative pressure can be generated. On the side facing the sheet conveying path, the chamber has openings over which the suction belt runs.
Nach einer Weiterbildung der Erfindung ist der Bogenleiteinrichtung ein Lüfter zugeordnet, mit dem wahlweise ein Über- oder ein Unterdruck erzeugbar ist.
Das hat den Vorteil, das in der zweiten Betriebsstellung zum Transport der Bogen ein Unterdruck anlegbar ist, der über das Saugband auf die Bogenunterseiten wirkt und in der ersten Betriebsstellung durch Anlegen eines Überdrucks ein Luftpolster unter den zum Auslegerstapel bewegten Bogen aufgebaut werden kann, was ein Abschmieren von Druckfarbe verhindert und die Trocknung der Unterseiten der Bogen begünstigt. Beim Transport von Bogen, die nur im Schöndruck bedruckt wurden, wird auch in der ersten Betriebsstellung ein Unterdruck angelegt, der die Hinderkanten der Bogen auf dem Saugband hält.According to a development of the invention, the sheet guiding device is assigned a fan with which either an overpressure or a negative pressure can be generated.
This has the advantage that in the second operating position for transporting the sheet, a negative pressure can be applied, which acts on the suction side of the sheet underside and in the first operating position by applying an overpressure, an air cushion can be built under the sheet moving to the delivery stack, which prevents smearing of ink and favors the drying of the undersides of the sheet. When transporting sheets that have been printed only in straight printing, a negative pressure is applied in the first operating position, which holds the Hind edges of the sheet on the suction belt.
Nach einer anderen Weiterbildung der Erfindung ist über der Bogenleiteinrichtung eine Blaseinrichtung angeordnet, die mit auf die Oberseiten der Bogen wirkt und in der zweiten Betriebsstellung das Ansaugen der Unterseiten der Bogen an das Saugband begünstigt.According to another embodiment of the invention, a blowing device is arranged above the sheet guiding device, which acts on the upper sides of the sheet and in the second operating position favors the suction of the undersides of the sheet to the suction belt.
Eine andere Weiterbildung der Erfindung sieht vor, das Bogenfördersystem mit umlaufenden Greiferwagen mit Greifern auszubilden und als Steuermittel eine verschwenkbare Greifersteuerkurve vorzusehen, mit der die Greifer betätigbar sind. Die Greifersteuerkurve ist mit der Bogenleiteinrichtung so verbunden, dass bei Verschwenken der Bogenleiteinrichtung auch die Greifersteuerkurve verschwenkt wird. Das hat den Vorteil, dass das Umschalten der Bogenablage von einer Ablage auf den Auslegerstapel zu einer Ablage in der Bogenaufnahmeeinrichtung oder zurück mit nur einem auf die Bogenleiteinrichtung oder die Bogenaufnahmeeinrichtung wirkenden Antrieb bewirkbar ist.Another development of the invention provides to form the sheet conveying system with rotating gripper carriage with grippers and provide as a control means a pivotable gripper cam, with which the gripper can be actuated. The gripper cam is connected to the sheet guiding device so that upon pivoting of the sheet guiding device and the gripper cam is pivoted. This has the advantage that the switching of the sheet tray from a tray on the delivery stack to a tray in the sheet receiving device or back with only one acting on the sheet guiding device or the sheet receiving device drive is effected.

Die Bogenleiteinrichtung 7.1 ist aus einer ersten Betriebsstellung 9, dargestellt mit durchgehender Linie, in der sie die von dem Bogenfördersystem dem Auslegerstapel 5 zuzuführenden Bogen leitet, in eine zweite Betriebsstellung 10, dargestellt mit gestrichelter Linie" in der sie von dem Bogenfördersystem freigegebene Bogen der Bogenaufnahmeeinrichtung 11 zuführt, verschwenkbar. Dazu ist auf der dem bogenführenden Zylinder 14 zugeordneten Seite der Bogenleiteinrichtung 7.1 ein Drehpunkt ausgebildet.
In der ersten Betriebsstellung 9 erstreckt sich die Bogenleiteinrichtung 7.1 parallel zum unteren Trum der Kette 3.
Der Bogenleiteinrichtung 7.1 ist in Förderrichtung eine weitere Bogenleiteinrichtung 7.2 nachgeordnet, die ebenfalls eine Kammer mit Öffnungen und einen Lüfter 12.2 umfasst, mit dem im Kammerinneren ein Unterdruck erzeugbar ist.
Grundsätzlich kann die Bogenleiteinrichtung 7.1 an beliebiger Stelle unterhalb des Bogenförderweges angeordnet sein, was auch eine Anordnung nach der weiteren Bogenleiteinrichtung 7.2 oder zwischen zwei weiteren Bogenleiteinrichtungen 7.2 mit einschließt.
Dem Abbremsen der Bogen dient eine unmittelbar vor dem Auslegerstapel 5 angeordnete und als Saugwalze ausgebildete Bogenbremse 6.
