Definitions

  • the invention relates to a device for transporting sheets printed in a printing unit by means of chain transfer systems according to the preamble of the first claim.
  • the gripper supports of the gripper systems protrude beyond the pitch circle diameter of deflection chain wheels, around which the transport chains are guided by a printing press cylinder in the region of the takeover point of the sheets.
  • the gripper supports of the gripper systems run during the sheet transfer on a radius which is approximately equal to the radius of the gripper supports of the grippers of the printing press cylinder. This means that the gripper pads of the gripper systems move faster than the transport chains, each guided by a deflection sprocket, during the sheet transfer. If the transport chains then run off the deflection sprockets and continue in a straight line, the speed of the gripper pads of the gripper systems is reduced to the speed of the transport chain.
  • the rear end of the sheet may not have left the printing press cylinder at this point and is accordingly moved forward faster than the front end of the sheet is pulled off.
  • the bow loses its tension and can form waves that lead to an increased risk of lubrication.
  • the sheet sticks to the rubber cylinder interacting with the impression cylinder until it is torn off. This can lead to permanent deformation of the arch.
  • changes in length of the printing paper can occur during printing due to a wide variety of influences. For example, the flexing process of the Arches in the printing zone and the different expansions caused by different moisture or color. As a result of this stretching of the paper, the gripper tension on the sheet changes constantly. As a result, doubling phenomena can occur especially towards the end of the sheet.
  • the invention has for its object to provide a device of the type mentioned in such a way that the sheet is removed from the impression cylinder after transfer to the gripper systems of the transport chains with approximately the same tension until the sheet end has left the printing line.
  • the sheets are removed from the printing cylinder 1 by means of chain transfer systems and transported to a printing unit or to the delivery.
  • the chain transfer systems comprise gripper carriages 2 carrying grippers, which are arranged between transport chains 12.
  • the gripper carriages 2 have a gripper support spindle 15 and a gripper shaft 16 (FIG. 2) in a known manner. These carry grippers spaced apart from one another, the gripper support 14 of which is rotatably mounted on the gripper support spindle 15 and the gripper fingers 17 of which are rotatably mounted on the gripper shaft 16. In the usual way, the gripper fingers 17 are pivoted in each case by rotating the gripper shaft 16 to detect and release an arc. A gripper control roller 13 running over a curve, not shown, is used for this.
  • the transport chains 12 are each guided around a deflection sprocket 23, the pitch circle diameter of which is smaller than the diameter of the printing press cylinder 1.

Abstract

Die Erfindung betrifft eine Vorrichtung zum Transport von in einem Druckwerk bedruckten Bogen mittels Kettenübergabesystemen, welche Greifer tragende Greiferwagen aufweisen, die an Transportketten angelenkt durch Laufrollen geführt sind, die in Führungsschienen laufen. Um den Bogen mit annähernd gleicher Spannung vom Druckzylinder abzunehmen bis das Bogenende die Drucklinie verlassen hat, ist der Greiferwagen (2) durch vorgebbare Federkraft (8) mittels einer Federabstützung (4, 8 bis 11) um die Drehachse (18) schwenkbar gelagert und mittels einer Laufrolle (7) in Führungsschienen (5, 6) für die Transportketten (12) verriegelbar sowie nach der Übergabe des Bogens an den Greiferwagen (2) durch eine Aussparung (24) in der äußeren Führungsschiene (6) entriegelbar. Dadurch kann die von dem Greiferwagen (2) auf den Bogen ausübbare Zugspannung durch Federkraft (8) auf einer Wegstrecke AA-BB reguliert werden, die von der Länge der Aussparung (24) in der äußeren Führungsschiene (6) bestimmt ist.The invention relates to a device for transporting sheets printed in a printing unit by means of chain transfer systems, which have gripper-carrying gripper carriages, which are articulated on transport chains by rollers which run in guide rails. In order to remove the sheet from the printing cylinder with approximately the same tension until the sheet end has left the printing line, the gripper carriage (2) is pivotably mounted about the axis of rotation (18) by means of a predeterminable spring force (8) by means of a spring support (4, 8 to 11) and by means of A roller (7) can be locked in guide rails (5, 6) for the transport chains (12) and unlocked after the sheet has been transferred to the gripper carriage (2) through a recess (24) in the outer guide rail (6). As a result, the tension that can be exerted on the sheet by the gripper carriage (2) can be regulated by spring force (8) over a distance AA-BB, which is determined by the length of the recess (24) in the outer guide rail (6).

Description

Die Erfindung betrifft eine Vorrichtung zum Transport von in einem Druckwerk bedruckten Bogen mittels Kettenübergabe­systemen nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a device for transporting sheets printed in a printing unit by means of chain transfer systems according to the preamble of the first claim.

Vorrichtungen genannter Gattung sind allgemein bekannt. Beispielsweise wird eine derartige Vorrichtung in der DE-PS 830 959 beschrieben.Devices of the type mentioned are generally known. For example, such a device is described in DE-PS 830 959.

Bei derartigen Vorrichtungen ragen die Greiferauflagen der Greifersysteme über den Teilkreisdurchmesser von Umlenk­kettenräder hinaus, um die die Transportketten im Bereich der Übernahmestelle der Bogen von einem Druckmaschinen­zylinder geführt sind. Die Greiferauflagen der Greifer­systeme laufen während der Bogenübergabe auf einem Radius, der etwa gleich dem Radius der Greiferauflagen der Greifer des Druckmaschinenzylinders ist. Somit bewegen sich die Greiferauflagen der Greifersysteme während der Bogenüber­gabe schneller als die um je ein Umlenkkettenrad geführten Transportketten. Laufen anschließend die Transportketten von den Umlenkkettenräder ab und etwa geradlinig weiter, so vermindert sich die Geschwindigkeit der Greiferauflagen der Greifersystemen auf die Geschwindigkeit der Transportkette. Das hintere Ende des Bogens hat jedoch zu diesem Zeitpunkt unter Umständen noch nicht den Druckmaschinenzylinder ver­lassen und wird dementsprechend schneller vorwärts bewegt als das vordere Ende des Bogens abgezogen wird. Hierdurch verliert der Bogen seine Spannung und kann Wellen bilden, die zu einer erhöhten Abschmiergefahr führen. Außerdem bleibt der Bogen an dem mit dem Druckzylinder zusammen­wirkenden Gummizylinder haften, bis er abgerissen wird. Dies kann zu einer bleibenden Verformung des Bogens führen. Außerdem können während des Druckvorganges durch unter­schiedlichste Einwirkungen Längenänderungen des Druck­papiers auftreten. Beispielsweise seien der Walkprozeß des Bogens in der Druckzone und die durch unterschiedliche Feuchtigkeit bzw. Farbe verursachten unterschiedlichen Dehnungen zu erwähnen. Infolge dieser Dehnungen des Papiers verändert sich die Greiferspannung am Bogen ständig. Als Folge können Doubliererscheinungen insbesondere zum Bogen­ende hin auftreten.In devices of this type, the gripper supports of the gripper systems protrude beyond the pitch circle diameter of deflection chain wheels, around which the transport chains are guided by a printing press cylinder in the region of the takeover point of the sheets. The gripper supports of the gripper systems run during the sheet transfer on a radius which is approximately equal to the radius of the gripper supports of the grippers of the printing press cylinder. This means that the gripper pads of the gripper systems move faster than the transport chains, each guided by a deflection sprocket, during the sheet transfer. If the transport chains then run off the deflection sprockets and continue in a straight line, the speed of the gripper pads of the gripper systems is reduced to the speed of the transport chain. However, the rear end of the sheet may not have left the printing press cylinder at this point and is accordingly moved forward faster than the front end of the sheet is pulled off. As a result, the bow loses its tension and can form waves that lead to an increased risk of lubrication. In addition, the sheet sticks to the rubber cylinder interacting with the impression cylinder until it is torn off. This can lead to permanent deformation of the arch. In addition, changes in length of the printing paper can occur during printing due to a wide variety of influences. For example, the flexing process of the Arches in the printing zone and the different expansions caused by different moisture or color. As a result of this stretching of the paper, the gripper tension on the sheet changes constantly. As a result, doubling phenomena can occur especially towards the end of the sheet.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art derart auszubilden, daß der Bogen nach der Übergabe an die Greifersysteme der Transportketten mit annähernd gleicher Spannung vom Druckzylinder abgenommen wird bis das Bogenende die Drucklinie verlassen hat.Starting from this prior art, the invention has for its object to provide a device of the type mentioned in such a way that the sheet is removed from the impression cylinder after transfer to the gripper systems of the transport chains with approximately the same tension until the sheet end has left the printing line.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merk­male des ersten Patentanspruches. Weiterbildungen der Erfindung sind in den Unteransprüchen, der Zeichnung und der Beschreibung enthalten.This object is achieved by the characterizing features of the first claim. Further developments of the invention are contained in the subclaims, the drawing and the description.

Die Erfindung wird nachstehend anhand der Zeichnung in einem Ausführungsbeispiel näher erläutert.The invention is explained below with reference to the drawing in one embodiment.

  • Fig. 2 eine Schnittdarstellung der seit­lichen Führung mit Verbindung von Greiferwagen zur Transportkette,
  • Fig. 3 den Schnitt AA nach Fig. 2,

It shows:

  • 2 is a sectional view of the lateral guide with connection of the gripper carriage to the transport chain,
  • 3 shows the section AA according to FIG. 2,
  • Fig. 4 shows a detail.

Vom Druckzylinder 1 werden die Bogen mittels Kettenüber­gabesystemen abgenommen und zu einem Druckwerk oder zur Auslage transportiert. Die Kettenübergabesysteme umfassen Greifer tragende Greiferwagen 2, die zwischen Transport­ketten 12 angeordnet sind. Die Greiferwagen 2 weisen in bekannter Weise eine Greiferauflagespindel 15 und eine Greiferwelle 16 (Fig. 2) auf. Diese tragen voneinander beabstandete Greifer, deren Greiferauflage 14 an der Greiferauflagespindel 15 und deren Greiferfinger 17 an der Greiferwelle 16 drehbar gelagert sind. In üblicher Weise werden jeweils die Greiferfinger 17 durch Drehen der Grei­ferwelle 16 zur Erfassung und Freigabe eines Bogens ver­schwenkt. Hierfür wird eine über eine nicht dargestellte Kurve laufende Greifersteuerrolle 13 verwendet. Im Bereich der Übernahmestelle der Bogen vom Druckmaschinenzylinder 1 sind die Transportketten 12 um je ein Umlenkkettenrad 23 geführt, dessen Teilkreisdurchmesser kleiner als der Durch­messer des Druckmaschinenzylinders 1 ist.The sheets are removed from the printing cylinder 1 by means of chain transfer systems and transported to a printing unit or to the delivery. The chain transfer systems comprise gripper carriages 2 carrying grippers, which are arranged between transport chains 12. The gripper carriages 2 have a gripper support spindle 15 and a gripper shaft 16 (FIG. 2) in a known manner. These carry grippers spaced apart from one another, the gripper support 14 of which is rotatably mounted on the gripper support spindle 15 and the gripper fingers 17 of which are rotatably mounted on the gripper shaft 16. In the usual way, the gripper fingers 17 are pivoted in each case by rotating the gripper shaft 16 to detect and release an arc. A gripper control roller 13 running over a curve, not shown, is used for this. In the area of the takeover point of the sheets from the printing press cylinder 1, the transport chains 12 are each guided around a deflection sprocket 23, the pitch circle diameter of which is smaller than the diameter of the printing press cylinder 1.

Die Seitenteile des Greiferwagens 2 sind in einer Drehachse 18 gelenkig mit je einer Trägerplatte 3 verbunden, die an Kettenbolzen 21, 22 der Transportketten 12 befestigt ist. Die Transportketten 12 sind außerdem in Führungsschienen 5, 6 geführt. Der Greiferwagen 2 ist durch vorgebbare Feder­kraft mittels einer Federabstützung 4, 8 bis 11 um die Drehachse 18 schwenkbar gelagert. Die Drehachse 18 verläuft verzugsweise durch den Massenmittelpunkt des Greiferwagens 2. Ferner ist jeder Greiferwagen 2 mittels einer Laufrolle 7 in den Führungsschienen 5, 6 verriegelbar und nach Über­gabe des Bogens vom Druckmaschinenzylinder 1 an die Greiferwagen 2 wieder entriegelbar. Hierzu weist die äußere Führungsschiene 6 eine Aussparung 24 derart auf, daß die von dem Greiferwagen 2 auf den Bogen ausübbare Zugspannung durch Federkraft der Feder 8 auf einer Weg­ strecke AA-BB regulierbar ist, die von der Länge der Aussparung 24 in der äußeren Führungsschiene 6 bestimmt ist. Die Feder 8 ist auf einer Federstange 9 geführt, die an einem Ende im Gelenk 11 mit einer abgewinkelten Abstützung 4 verbunden ist und die am anderen Ende in einem festen Anschlag 10.1 am Greiferwagen 2 längsverschiebbar geführt ist. Die Federkraft der Feder 8 ist zwischen dem festen Anschlag 10.1 und einem einstellbaren Anschlag 10.2 stufenlos verstellbar. Gemäß Fig. 4 sind Trägerplatte 3 und abgewinkelte Abstützung 4 durch Schrauben 19, 20 fest miteinander verbunden.The side parts of the gripper carriage 2 are connected in an articulated manner in an axis of rotation 18 to a respective carrier plate 3 which is fastened to chain pins 21, 22 of the transport chains 12. The transport chains 12 are also guided in guide rails 5, 6. The gripper carriage 2 is pivotally mounted about the axis of rotation 18 by a predeterminable spring force by means of a spring support 4, 8 to 11. The axis of rotation 18 extends through the center of mass of the gripper carriage 2. Furthermore, each gripper carriage 2 can be locked in the guide rails 5, 6 by means of a roller 7 and can be unlocked again after the sheet has been transferred from the printing press cylinder 1 to the gripper carriage 2. For this purpose, the outer guide rail 6 has a recess 24 in such a way that the tensile stress that can be exerted on the sheet by the gripper carriage 2 is in one way by the spring force of the spring 8 Route AA-BB is adjustable, which is determined by the length of the recess 24 in the outer guide rail 6. The spring 8 is guided on a spring rod 9 which is connected at one end in the joint 11 to an angled support 4 and which is guided in a longitudinally displaceable manner in a fixed stop 10.1 on the gripper carriage 2 at the other end. The spring force of the spring 8 is continuously adjustable between the fixed stop 10.1 and an adjustable stop 10.2. 4, carrier plate 3 and angled support 4 are firmly connected to one another by screws 19, 20.

Die Kette 12 weist ferner ein bananenförmiges Kettenglied 25 auf, welches die Laufrolle 7 umgibt.The chain 12 also has a banana-shaped chain link 25 which surrounds the roller 7.

Die äußere Führungsschiene 6 ist an der Innenseite, wie bereits erwähnt, beginnend ab der Übergabe, ausgespart. Diese Aussparung 24 kann eine Kurvenform oder eine kreis­förmige Form aufweisen. Mit Hilfe der Federabstützung 4, 8 bis 11 wird nun der Greiferwagen 2 um die Drehachse 18 geschwenkt, wobei nur bei max. Abschwenkung die Laufrolle 7 an der äußeren Führungsschiene 6 anläuft. Vorzugsweise weist aber die Laufrolle 7 keine Berührung mit der äußeren Führungsschiene 6 auf, so daß die von dem Greifersystem des Greiferwagens 2 auf den Bogen ausübbare Zugspannung auf der gesamten Wegstrecke AA-BB bis weit nach Ablauf des Bogenan­fanges vom Umlenkkettenrad 23 durch die Federkraft der Feder 8 regulierbar ist. Dadurch erfährt der Bogen im Bereich der Aussparung 24 eine federnde Voreilung und wird stets gestreckt geführt, bis das Bogenende die Druckzone verlassen hat. Die federnde Voreilung wirkt somit sowohl im Bereich des Umlenkkettenrades als auch auf der sich anschließenden geraden Wegstrecke.The outer guide rail 6 is recessed on the inside, as already mentioned, starting from the handover. This recess 24 can have a curve shape or a circular shape. With the help of the spring support 4, 8 to 11, the gripper carriage 2 is now pivoted about the axis of rotation 18, only at max. Swiveling the roller 7 starts on the outer guide rail 6. Preferably, however, the roller 7 has no contact with the outer guide rail 6, so that the tension exerted by the gripper system of the gripper carriage 2 on the sheet over the entire distance AA-BB until far after the end of the sheet from the deflection sprocket 23 by the spring force of the spring 8 is adjustable. As a result, the sheet in the area of the recess 24 experiences a resilient advance and is always guided in a stretched manner until the sheet end has left the printing zone. The resilient lead thus acts both in the area of the deflection sprocket and on the subsequent straight path.
