Description

Die Erfindung betrifft im allgemeinen eine Druckmaschine und im besonderen einen Einführbandmechanismus eines Falzapparats für eine Druckmaschine zur Auslage von Signaturen.The invention relates generally to a printing press and in particular an infeed belt mechanism Folding apparatus for a printing machine for the display of Signatures.

Einführbandsysteme werden gewöhnlich für das Befördern von Signaturen aus einer Druckmaschine auf einen Stapel eingesetzt. Ein Einführbandsystem umfaßt normalerweise mehrere Einführbandmechanismen, die in einem Abstand voneinander Seite an Seite angeordnet sind, so daß sie mit den Signaturen über deren Breite in Kontakt kommen. Jeder Einführbandmechanismus umfaßt ein Einführband an der einen Seite und ein korrespondierendes, in Gegenrichtung umlaufendes Einführband an der anderen Seite, um einen Signaturdurchlauf zu bilden, so daß die Signatur an ihren beiden Seiten ergriffen und durch den Signaturdurchlauf befördert werden kann. Oft verlassen die Signaturen den Signaturdurchlauf, um in den Taschen eines Schaufelrads oder mehrerer Schaufelräder aufgenommen zu werden. Während der Rotation des Schaufelrads oder der Schaufelräder werden dann die Signaturen auf einem Stapel abgelegt, wie in dem U.S. Patent Nr. 5,112,033 beschrieben, das hiermit als Bezugspatent integriert wird.Conveyor belt systems are typically used for conveying Signatures from a printing press on a stack used. An infeed conveyor system typically includes multiple infeed belt mechanisms at a distance are arranged side by side from each other, so that they with the signatures come into contact across their width. Everyone Infeed belt mechanism includes an infeed belt at one Side and a corresponding one, in the opposite direction circumferential infeed belt on the other side to one Form signature run so that the signature on their seized on both sides and through the signature run can be promoted. The signatures often leave the Signature pass to in the pockets of a paddle wheel or several paddle wheels. During the Rotation of the paddle wheel or the paddle wheels are then the signatures placed on a stack as in the U.S. No. 5,112,033, which is hereby described as Reference patent is integrated.

Die Einführbänder weisen normalerweise Führungswalzen und eine Antriebswalze auf, welche an der Innenseite des Einführbandes zu dessen Führung und Antrieb angeordnet sind. Es befinden sich Führungswalzen, i.e. Austrittwalzen, an dem unteren Ende des Einführbandes, wo die Signatur austritt.The infeed belts usually have guide rollers and a drive roller on the inside of the Entry belt are arranged to guide and drive it. There are guide rollers, i.e. Exit rollers on which lower end of the infeed belt where the signature exits.

Eine Austrittwalze ist normalerweise fest angebracht, während die andere Austrittwalze in der Richtung der fest angebrachten Walze mit der Vorspannung einer einzigen Feder beaufschlagt ist, um den harten Griff auf die Signatur beim Eintritt in ein Schaufelrad aufrechtzuerhalten. Dieser harte Griff oder Preßdruck ist notwendig, um die Beförderung der Signaturen in die Schaufelräder und deren Aufnahme darin zu unterstützen. Beim Passieren der Signaturen durch die Austrittwalzen ergibt sich ein Anfang-Ende-Spalt zwischen den einzelnen Signaturen, so daß die Spitzen aufeinanderfolgender Schaufelräder zwischen den Signaturen passieren können. Wenn die mit einer Federvorspannung beaufschlagten Austrittwalzen auf diesen Spalt zwischen den Signaturen treffen, drücken diese sich an die fest angebrachten Walzen und lösen sich wieder, wenn sie auf die Vorderkante der nächsten Signatur treffen. Dieses erzeugt ein Schwingungsphänomen, was eine hohe dynamische Belastung für die fest angebrachten Walzen darstellt.An exit roller is normally attached while the other exit roller in the direction of the fixed attached roller with the bias of a single spring is applied to the hard grip on the signature when Maintain entry into a paddle wheel. This hard one Handle or baling pressure is necessary to carry the Signatures in the paddle wheels and their inclusion in them support. When passing the signatures through the Exit rolls result in a start-end gap between the individual signatures so that the tips are consecutive Paddle wheels can pass between the signatures. If the exit rollers loaded with a spring preload meet this gap between the signatures, press these adhere to the fixed rollers and come loose again when they are on the leading edge of the next signature to meet. This creates a vibration phenomenon, what a high dynamic load for the fixed rollers represents.

Vorzeitiger Verschleiß und Versagen der Lager, Bänder oder anderer Komponenten, sowie Reibkorrosion der belasteten Komponenten und Schlupf der die Austrittwalzen haltentenden Austrittwatzenhebel können dann auftreten. Der Ersatz dieser Komponenten kann zeitaufwendig und kostspielig sein.Premature wear and failure of the bearings, belts or other components, as well as fretting corrosion of the loaded Components and slip of the ones holding the exit rollers Discharge leg levers can then occur. The replacement of this Components can be time consuming and expensive.

Es ist eine Aufgabe der vorliegenden Erfindung, das Schlagen, welches durch das Passieren der Signaturen durch die Austrittwalzen des Einführbandmechanismus verursacht wird, zu reduzieren.It is an object of the present invention to hit, which by passing the signatures through the Exit rolls of the infeed belt mechanism are caused to to reduce.

Es ist eine weitere Aufgabe der Erfindung, den vorzeitigen Verschleiß von Lagern, Bändern oder anderen Komponenten zu verhindern.It is another object of the invention, the premature one Wear on bearings, belts or other components prevent.

Somit sieht die vorliegende Erfindung einen Falzapparat vor, welcher die folgenden Merkmale aufweist:
mindestens einen Einführbandmechanismus mit einem ersten Einführband und einer ersten Austrittwalze und einem angebrachten Walze mit der Vorspannung einer einzigen Feder beaufschlagt ist, um den harten Griff auf die Signatur beim Eintritt in ein Schaufelrad aufrechtzuerhalten. Dieser harte Griff oder Preßdruck ist notwendig, um die Beförderung der Signaturen in die Schaufelräder und deren Aufnahme darin zu unterstützen. Beim Passieren der Signaturen durch die Austrittwalzen ergibt sich ein Anfang-Ende-Spalt zwischen den einzelnen Signaturen, so daß die Spitzen aufeinanderfolgender Schaufelräder zwischen den Signaturen passieren können. Wenn die mit einer Federvorspannung beaufschlagten Austrittwalzen auf diesen Spalt zwischen den Signaturen treffen, drücken diese sich an die fest angebrachten Walzen und lösen sich wieder, wenn sie auf die Vorderkante der nächsten Signatur treffen. Dieses erzeugt ein Schwingungsphänomen, was eine hohe dynamische Belastung für die fest angebrachten Walzen darstellt.The present invention thus provides a folder which has the following features:
at least one infeed belt mechanism with a first infeed belt and a first exit roller and an attached roller is biased by a single spring to maintain the hard grip on the signature when entering a paddle wheel. This hard grip or pressure is necessary to support the transport of the signatures into the paddle wheels and their inclusion in them. When the signatures pass through the exit rollers, there is a start-end gap between the individual signatures, so that the tips of successive paddle wheels can pass between the signatures. When the exit rollers, which are spring-loaded, hit this gap between the signatures, they press against the firmly attached rollers and come loose again when they hit the front edge of the next signature. This creates an oscillation phenomenon, which places a high dynamic load on the fixed rollers.

Der Ersatz dieser Komponenten kann zeitaufwendig und kostspielig sein.Premature wear and failure of the bearings, belts or other components, as well Fretting corrosion of the loaded components and slippage of the exit rollers then exit roller levers can occur. The replacement of these components can be time consuming and costly.

EP 0 542 550 A1 bezieht sich auf eine Vorrichtung und ein Verfahren zur Transfer flacher Artikel. In der Vorrichtung werden zwei Paare von Zuführwalzen benutzt, um flache Artikel zu transportieren, wie beispielsweise Umschläge, Magazine und Zeitungen. Diese werden vereinzelt, eines nach dem anderen von einem Stapel mittels eines Transportmittels zu einer Verarbeitungsstation zum Drucken und Etikettieren transportiert. Erfindungsgemäße Vorrichtung und Verfahren erlauben unabhängiges Einstellen des Spaltes zwischen den Rollen, so daß ein flacher Artikel, wie beispielsweise ein Umschlag in den Spalt zwischen den Walzen eingeführt werden kann, wobei das jeweilige Walzenpaar gleichmäßigen Druck im Spalt auf den Artikel ausübt. Der Druck im Spalt zwischen den Führungswalzen wird durch einen Mechanismus herbeigeführt, welcher ein Anheben und ein Absenken der oberen angetriebenen Zuführwalze, vorzugsweise über eine Drehbewegung, herbeiführt. Nach Freigabe durch die Vorrichtung erzeugen die vorgespannten Walzen einen jeweils gleichförmig verlaufenden Druck im Walzenspalt auf den Artikel, auch dann, wenn sich die Spaltenbreite ändert, wie beispielsweise bei verschiedenen Stärken der zu verarbeitenden Materialien.EP 0 542 550 A1 relates to a device and a method for transferring flat Items.

The stud 17 is on one Frame part 28 attached such that the left lever 16 and the left exit roller 15 with a spring bias the right exit roller 25 can be applied, as in following is described in more detail. On the right is the right exit roller 25 at one end of a right one Lever 26 mounted, and the right lever 26 is with his the other end to a fixed stud 27 stored, which is fixed to the frame part 28, so that the right exit roller 25 can rotate, but during the Operationally fixed in translation.

Es ist auch ein Arm 29 mit einer Ober- und Unterseite mittels eines Klemmbolzens an der Büchse 18 befestigt. Eine Spiralfeder 60 ist um einen Vorspannbolzen 62 gewunden, der einen Bolzenkopf 63 aufweist, und ist zwischen dem Bolzenkopf 63 und der Oberseite des Arms 29 beweglich. Der Vorspannbolzen 62 wird in ein an dem Rahmenteil 28 befestigtes Montagestück 65 geschraubt und dringt dabei auch durch ein Loch in dem Arm 29. Die Vorspannung der Spiralfeder 60 kann durch Anziehen oder Lockern des Bolzens 62 geändert werden. Bei einer Änderung der Vorspannung kann der Klemmbolzen des Arms 29 gelockert werden, so daß der Arm 29 sich an der Büchse 18 drehen kann, und später wieder festgeschraubt werden. Dies kann erfolgen, ohne die Position des Hebels 16, der seinen eigenen Klemmbolzen hat, zu beeinträchtigen.It is also an arm 29 with a top and bottom means a clamping bolt attached to the sleeve 18. A Coil spring 60 is wound around a biasing pin 62 which has a bolt head 63, and is between the Bolt head 63 and the top of the arm 29 movable. Of the Preload bolt 62 is in a on the frame part 28th fastened mounting piece 65 screwed and also penetrates through a hole in the arm 29. The preload of the Coil spring 60 can be tightened or loosened Bolt 62 can be changed. If the Preload can loosen the clamping bolt of the arm 29 so that the arm 29 can rotate on the sleeve 18, and screwed back in later. This can be done without the position of the lever 16, which is its own Clamping bolt has to affect.

Zwischen der Oberfläche des Montagestückes 65 und der Unterseite des Armes 29 und um den Bolzen 62 befindet sich eine zweite Feder 61, die z.B. aus einem gummiartigen Material bestehen kann und vorzugsweise eine hohe Federkonstante aufweist. Die zweite Feder 61 hat auch vorzugsweise zusätzliche Dämpfungseigenschaften, um Kräfte- und Schwingungseinwirkungen zu vermindern.Between the surface of the mounting piece 65 and the Bottom of the arm 29 and around the bolt 62 is located a second spring 61, e.g. from a rubbery Material can consist and preferably a high Has spring constant. The second spring 61 also has preferably additional damping properties in order To reduce the effects of forces and vibrations.

Für eine Hochgeschwindigkeits-Rollenrotationsdruckmaschine, die mit Geschwindigkeiten bis zu 914 m/min (3000 ft/min) läuft, würde eine bevorzugte Federkonstante für die Spiralfeder ungefähr 22,5-45 kg pro 2,54 cm (50-100 lbs/inch) und eine bevorzugte Federkonstante für die zweite Feder ungefähr 225-450 kg pro 2,54 cm (500-1000 lbs/inch) betragen, jedoch kann die optimale Federkonstante variieren, was von der Bahndicke, den normalen Betriebsgeschwindigkeiten und anderen Faktoren abhängt.For a high speed web-fed rotary press, which at speeds up to 914 m / min (3000 ft / min) would be a preferred spring constant for the Coil spring approximately 22.5-45 kg per 2.54 cm (50-100 lbs / inch) and a preferred spring constant for the second spring approximately 225-450 kg per 2.54 cm (500-1000 lbs / inch), however, the optimal spring constant can vary, which of the web thickness, the normal operating speeds and other factors.

Während des Betriebs werden die einzelnen Signaturen 3, 4 zwischen den korrespondierenden Einführbändern 11, 21 bewegt. Die Spiralfeder 60 zwingt den Arm 29 und damit den Hebel 16 und die linke Austrittwalze 15, sich durch die Büchse 18 in Richtung der rechten Austrittwalze 25 zu bewegen. Die zweite Feder 61 wirkt dieser Bewegung entgegen. Wenn also der Spalt zwischen zwei Signaturen die Austrittwalzen 15, 25 passiert, absorbiert die Feder 61 mit hoher Federkonstante die hohe dynamische Belastung und vermindert somit beträchtlich das durch den jeweiligen Spalt zwischen den Signaturen verursachte Schlagen.During operation, the individual signatures 3, 4 moved between the corresponding infeed belts 11, 21. The spiral spring 60 forces the arm 29 and thus the lever 16 and the left exit roller 15, through the sleeve 18 in To move toward the right exit roller 25. The second Spring 61 counteracts this movement. So if the gap the exit rollers 15, 25 pass between two signatures, the spring 61 with the high spring constant absorbs the high one dynamic load and thus significantly reduces that through the respective gap between the signatures beating caused.

Wie in Fig. 3 gezeigt, sind die auf den Bolzenkopf 63 wirkenden Kräfte durch die vorhandene Feder, die eine hohe Federkonstante aufweist, bedeutend vermindert. Die dargestellte Kurve 70 zeigt beim Betrieb der Maschine das Variieren der auf den Bolzenkopf 63 wirkenden Kräfte, während die dargestellte Kurve 71 das Wirken von Kräften auf einen ähnlichen Bolzenkopf zeigt, wo nur eine Spiralfeder zwischen einem Arm und dem Bolzenkopf wirkt. Der Zeitraum zwischen den Scheitelpunkten der Kurve 71 ist der Zeitraum, in welchem eine individuelle Signatur die Austrittwalzen passiert. As shown in FIG. 3, they are on the bolt head 63 acting forces through the existing spring, which is high Spring constant, significantly reduced. The curve 70 shows this when the machine is operating Varying the forces acting on the bolt head 63 while the curve 71 shown shows the action of forces on one Similar bolt head shows where only a coil spring between one arm and the bolt head. The period between The vertex of curve 71 is the period in which an individual signature passes the exit rollers.

Obschon die vorliegende Erfindung in dem oben beschriebenen Ausführungsbeispiel im einzelnen dargelegt ist, ist es denkbar, daß die Erfindung weitere Ausführungen umfaßt, und daß insbesondere andere Arten von Federn als Spiralfedern und gummiartige Federn verwendet werden können.Although the present invention is described in the above Embodiment is set out in detail, it is conceivable that the invention comprises further embodiments, and that in particular other types of springs than spiral springs and rubber-like springs can be used.
