Abstract

A conveyor for a sheet-fed rotary printing press for transferring sheets away from an impression cylinder includes a delivery cylinder disposed adjacent the impression cylinder, and a chain conveyor having a plurality of sheet grippers, adapted for moving the grippers about the delivery cylinder for successively engaging sheets on the impression cylinder. The delivery cylinder has a gap in its outer periphery for receiving successive of the sheet grippers during transfer of a sheet from the impression cylinder to the sheet grippers. The sheet grippers each include a support and a pivotable gripper finger, and a displacer mounted on and extending rearwardly of each gripper support for bridging the gap in the delivery cylinder within which the gripper is disposed during a sheet transfer operation, and for maintaining tension in the sheet during transfer from the impression cylinder to the chain conveyor. The displacer is comb shaped having a plurality of rearwardly extending arcute shaped teeth. A sheet support comb also may be supported on the delivery cylinder with its teeth forwardly extending in intermeshing relation with the teeth of the displacer so as to completely bridge the gap within which the sheet gripper is disposed. Antismear rollers or like elements may be disposed on the teeth of the displacer and the sheet support comb to facilitate smooth transfer of the sheet away from the compression cylinder.

Description

Die Erfindung betrifft eine Fördervorrichtung für eine Bogenrotationsdruckmaschine nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a conveyor device for a sheet-fed rotary printing press according to the preamble of the first claim.

Eine Fördervorrichtung mit diesen Merkmalen ist durch die DE-PS 2 111 049 bekannt geworden. Bei derartigen Fördervor­richtungen ragen die Greiferauflagen der Greifersysteme üblicherweise über den Teilkreisdurchmesser der Umlenk­kettenräder hinaus. Sie laufen während der Bogenübergabe auf einem Radius, der etwa gleich dem Radius der Greifer­auflagen der Greifer des Druckmaschinenzylinders ist. Laufen die Transportketten von den Umlenkkettenrädern ab und geradlinig weiter, so vermindert sich die Geschwindig­keit der Greiferauflagen auf die Geschwindigkeit der Transportketten. Das hintere Ende des Bogens hat zu diesem Zeitpunkt jedoch bei größeren Formaten den Druckmaschinen­zylinder noch nicht verlassen und wird dementsprechend schneller vorwärtsbewegt als der Bogenanfang abgezogen wird. Hierdurch verliert der Bogen seine Spannung und kann Wellen bilden, die zu einer erhöhten Abschmiergefahr führen. Außerdem wird der Bogen am Gummizylinder mit­genommen, bis er abgerissen wird. Dies kann zu einer blei­benden Verformung des Bogens führen. Um diese Nachteile zu beseitigen, ist es aus der oben genannten Patentschrift bekannt, einen Bogenverdränger gegen den Bogen zu drücken, um ihn nach der Übergabe an die Greifersysteme der Trans­portketten unter Spannung zu halten.A conveyor device with these features has become known from DE-PS 2 111 049. With such conveyor devices, the gripper supports of the gripper systems usually protrude beyond the pitch circle diameter of the deflection chain wheels. During the sheet transfer, they run on a radius which is approximately equal to the radius of the gripper pads of the grippers of the printing press cylinder. If the transport chains run off the deflection sprockets and continue in a straight line, the speed of the gripper pads reduces to the speed of the transport chains. At this point, however, the rear end of the sheet has not yet left the printing press cylinder in the case of larger formats and is accordingly moved forward faster than the sheet beginning 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 is carried along on the rubber cylinder until it is torn off. This can lead to permanent deformation of the arch. In order to eliminate these disadvantages, it is known from the above-mentioned patent specification to press a sheet displacer against the sheet in order to keep it under tension after transfer to the gripper systems of the transport chains.

Von Nachteil ist dabei, daß der Bogenverdränger am Bogen abschmiert und insbesondere nicht bereits unmittelbar nach Übergabe des Bogens an die Greifersysteme wirkt. Dadurch besteht die Gefahr, daß die vordere Kante der Abnahme­trommel bzw. die Tragscheiben infolge des Abknickens der Bogentangente abschmieren. Der Bogenanfang weicht insbesondere bei großem Trommelkanal gewissermaßen in den nichttragenden Bereich der Abnahmetrommel aus, bevor er durch den radial zwischen zwei Tragscheiben der Abnahmetrommel aus dem Kettenradius heraussteuerbaren Bogenverdränger ver­drängt werden kann. Das bedeutet, daß die das bekannte Mitlaufen des Bogens am Gummituch des Gummituchzylinders verhindernde Spannung durch einen an der Abnahmetrommel mittig zwischen zwei Tragscheiben heraussteuerbaren Bogen­verdränger nicht bereits von Anfang der Übergabe an erzeugt werden kann.The disadvantage here is that the sheet displacer lubricates the sheet and in particular does not act immediately after the sheet has been transferred to the gripper systems. As a result, there is a risk that the front edge of the take-off drum or the support disks will smear due to the kinking of the tangent. The beginning of the bow gives way especially in the case of a large drum channel, to a certain extent in the non-load-bearing area of the take-up drum, before it can be displaced by the arc displacer that can be controlled radially between two support disks of the take-up drum. This means that the known tension of the sheet on the rubber blanket of the blanket cylinder preventing tension can not be generated from the beginning of the handover by a sheet displacer that can be controlled centrally on the take-up drum between two support disks.

Aus der DE-PS 2 017 417 ist es zwar für Trans elübergabe­systeme bekannt, bei einer Abnahmetrommel, die an nur einem Teil des Mantels eine tragende Oberfläche aufweist, in den vom Bogen überdeckten Raum zwischen dieser tragenden Fläche und einer auf der Trommel ortsfest angeordneten Greiferein­richtung einen durch eine Blaslufteinrichtung gebildeten Bogenverdränger vorzusehen.From DE-PS 2 017 417 it is known for Trans elübergabeesysteme, with a take-off drum, which has a supporting surface on only a part of the jacket, in the arc-covered space between this supporting surface and a stationary gripper device arranged on the drum to provide an arc displacer formed by a blowing air device.

Es bereitet aber Schwierigkeiten, durch das gebildete Luftkissen das Abknicken der Bogentangente zu verhindern, wenn sehr hohe Zugkräfte auf den Bogen, z. B. bei Doppel­druckwerken einwirken und zur zeitweiligen Aufnahme von an umlaufenden Transportketten befestigten stabilen Greifer­systemen mit den zugehörigen Greiferwagen erheblich größere Trommelkanäle erforderlich werden. Die Blaslufteinrichtung läuft außerdem nur mit der Abnahmetrommel um und wirkt somit nur im Trommelbereich. Bei Kettenübergabesystemen kommt es zusätzlich auch darauf an, den Bogen zu stützen, nachdem die Transportketten den Kettenradius der Abnahme­trommel verlassen haben, um einen flatterfreien Bogenlauf in das nächste Druckwerk oder zur Bogenauslage zu bewirken. Außerdem ist von Nachteil, daß die Blaslufteinrichtung einen hohen lufttechnischen Aufwand und Steuerungsaufwand erfordert.However, it is difficult to prevent the tangent from kinking due to the air cushion formed when very high tensile forces are exerted on the arch, e.g. B. act on double printing units and considerably larger drum channels are required for the temporary reception of stable gripper systems attached to rotating transport chains with the associated gripper carriage. The blowing air device also only rotates with the take-off drum and thus only works in the drum area. In chain transfer systems, it is also important to support the sheet after the transport chains have left the chain radius of the take-up drum in order to ensure flutter-free sheet travel into the next printing unit or for sheet delivery. Another disadvantage is that the blowing air device requires a high level of ventilation and control effort.

Der Erfindung liegt deshalb die Aufgabe zugrunde, bei einer Fördervorrichtung eingangs genannter Gattung durch einen mechanischen Bogenverdränger den bedruckten Bogen bei ver­ringerter Abschmiergefahr unmittelbar nach Übergabe vom Druckzylinder an die Greifersysteme vom Anfang des Bogens her mit ausreichender Spannung bis zur Aufhebung des Greiferschlusses der an den umlaufenden Transportketten angeordneten Greifersysteme zu führen, d. h., bis zur nächsten Übergabe oder Auslage des Bogens mit dem Ketten­übergabesystem.The invention is therefore based on the object in a conveyor device of the type mentioned by a mechanical sheet displacer the printed sheet with reduced risk of smearing immediately after transfer from the pressure cylinder to the gripper systems from the beginning of the sheet with sufficient tension until the loosening of the gripper closure of the rotating transport chains to guide arranged gripper systems, d. i.e. until the next transfer or delivery of the sheet with the chain transfer system.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des ersten Patentanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen und der Zeichnung in Ver­bindung mit der Beschreibung.This object is achieved by the characterizing features of the first claim. Further developments result from the subclaims and the drawing in connection with the description.

Zur Überführung eines bedruckten Bogens 5 von einem Druckwerk zum nächsten Druckwerk oder zur Bogenauslage einer Bogenrotationsoffsetdruckmaschine durch Kettenüber­gabesysteme wird der Bogen in bekannter Weise von einem Druckzylinder 1 mittels an nicht dargestellten umlaufenden Transportketten vorgesehenen Greifersystemen 4, 19 abgenommen und um eine Abnahmetrommel 2 geführt. Die Greifersysteme 4, 19 weisen Greiferauflagen 4 und 19 auf, die in Greiferwagen 15 auf einer Greiferauflagenspindel 10 und einer Greiferwelle 11 gelagert mit den Transportketten verbunden sind (Figur 3). Die Abnahmetrommel 2 trägt zwei nicht dargestellte Umlenkkettenräder, über die die Transportketten laufen. Jedes Druckwerk weist in bekannter Weise außer dem Druckzylinder 1 nicht dargestellte Gummi- ­und Plattenzylinder auf.To transfer a printed sheet 5 from one printing unit to the next printing unit or for sheet delivery of a sheet-fed rotary offset printing press by chain transfer systems, the sheet is removed in a known manner from a printing cylinder 1 by means of gripper systems 4, 19 provided on rotating transport chains, not shown, and is guided around a removal drum 2. The gripper systems 4, 19 have gripper supports 4 and 19, which are connected to the transport chains in a gripper carriage 15 on a gripper support spindle 10 and a gripper shaft 11 (FIG. 3). The take-off drum 2 carries two deflection sprockets, not shown, over which the transport chains run. In addition to the printing cylinder 1, each printing unit has, in a known manner, rubber and plate cylinders.

Je nach Zügigkeit der Farbe, der Beschaffenheit der Gummi­tücher an deren Oberfläche und der Gestaltung des Bogen­laufes besteht die Möglichkeit, daß die Bogentangente beim Lauf des Bogens 5 über die tragenden Flächen der Abnahme­trommel 2 an der vorderen Trommelkante 14 abknickt. Dabei besteht die Gefahr des Abschmierens des bedruckten Bogens, wenn nicht verhindert wird, daß der Bogenanfang in den überdeckten Raum der Abnahmetrommel 2 gezogen wird.Depending on the briskness of the color, the nature of the rubber blankets on their surface and the design of the sheet run, there is the possibility that the sheet tangent bends when the sheet 5 runs over the supporting surfaces of the take-up drum 2 at the front drum edge 14. There is a risk of the printed sheet being smeared if it is not prevented that the beginning of the sheet is pulled into the covered space of the take-up drum 2.

Erfindungsgemäß geschieht das dadurch, daß die Zugspannung im Bogen von Beginn der Übergabe des Bogens 5 vom Druck­zylinder 1 an die Greifersysteme 4, 19 aufrecht erhalten wird. Der vom bedruckten Bogen 5 überdeckte Raum zwischen den an den umlaufenden Transportketten angeordneten Greifersystemen 4, 19 und einer gegenüberliegenden tragenden Fläche der Abnahmetrommel 2 wird unmittelbar nach Übergabe des Bogens 5 an die Greifersysteme 4, 19 durch einen an den Greifersystemen 4, 19 fest oder radial nach außen verstellbaren oder aus dem Kettenradius heraussteuer­baren Bogenverdränger 3 überbrückt, dessen gekrümmte Stützfläche annähernd den Radius der tragenden Flächen des Trommelmantels der Abnahmetrommel 2 aufweist.According to the invention, this is done in that the tension in the sheet is maintained from the start of the transfer of the sheet 5 from the impression cylinder 1 to the gripper systems 4, 19. The space covered by the printed sheet 5 between the gripper systems 4, 19 arranged on the circulating transport chains and an opposite supporting surface of the take-up drum 2 becomes fixed or radial immediately after the sheet 5 is transferred to the gripper systems 4, 19 by one on the gripper systems 4, 19 bridged adjustable or out of the chain radius arch displacer 3 bridged, the curved support surface has approximately the radius of the supporting surfaces of the drum shell of the take-up drum 2.

Der Bogenverdränger 3 kann dabei vollflächig oder ausgespart sein und axial verstellbar ausgebildet sein.The arc displacer 3 can be full-surface or recessed and axially adjustable.

Die radiale Verstellmöglichkeit erlaubt es, einen geringen Wegfehler beim Lauf des Bogens 5, welcher aus dem radialen Unterschied zwischen der Greiferauflage 4 und dem Durch­messer der tragenden Flächen der Abnahmetrommel 2 resultiert auszugleichen, wenn bei Verarbeitung von dünnen Bogen 5 die Greiferauflage 4 über den Radius der tragenden Flächen des Trommelmantels der Abnahmetrommel 2 hinaus eingestellt ist.The radial adjustment option allows to compensate for a small path error during the running of the sheet 5, which results from the radial difference between the gripper pad 4 and the diameter of the supporting surfaces of the take-off drum 2, if the gripper pad 4 is processed over the radius of the thin sheet 5 bearing surfaces of the drum shell of the take-off drum 2 is also set.

Schließlich kann der Bogenverdränger 3 unmittelbar nach der Übergabe des bedruckten Bogens an die Greifersysteme 4, 19 der Transportketten aus dem Kettenradius der Umlenkketten­räder herausgesteuert werden. Hierzu sind gemäß Figur 2 und Figur 3 beidseitig auf der Welle der Abnahmetrommel 2 Steuerrollen 7 angeordnet, die unter Federkraft 8 auf Kürven 12 ablaufen. Die Steuerrollen 7 sind an beiden Enden einer Traverse 17 befestigt, welche den Bogenverdränger 3 bzw. einen steuerbaren Bogenverdrängerkamm 6 an einem Ende trägt. In Gelenken 9 werden der Bogenverdrängerkamm 6 bzw. der Bogenverdränger 3 am anderen Ende mit den Greifer­systemen 4, 19 schwenkbar verbunden, um diese aus dem Kettenradius der Umlenkkettenräder kurvengesteuert auszuschwenken bzw. nachdem das Bogenende die Druckzone verlassen hat wieder zurückzuschwenken. Dadurch wird es möglich, den größeren Wegfehler beim verlangsamten Geradeauslaufen der Greifersysteme 4, 19 bis das Bogenende die Druckzone verlassen hat auszugleichen. Dadurch wird die bekannte Lockenbildung am Bogen 5 beseitigt. Außerdem ist die Abschmiergefahr verringert. Zugleich wird das Mit­laufen des Bogens insbesondere zum Bogenende hin am Gummi­zylinder verhindert, so daß der Bogen 5 dort nicht schäd­lich abgerissen werden kann. Abrißstreifen oder dergleichen Markierungen im Druckbild werden somit ebenfalls zuver­lässig verhindert.Finally, the sheet displacer 3 can be controlled out of the chain radius of the deflection chain wheels immediately after the printed sheet has been transferred to the gripper systems 4, 19 of the transport chains. For this purpose, according to FIG. 2 and FIG. 3, control rollers 7 are arranged on both sides of the shaft of the take-up drum and run on cams 12 under spring force 8. The control rollers 7 are attached to both ends of a cross member 17, which the bow displacer 3rd or carries a controllable sheet displacement comb 6 at one end. In joints 9, the bow displacement comb 6 or the bow displacer 3 are pivotally connected at the other end to the gripper systems 4, 19 in order to pivot them out of the chain radius of the deflection sprockets or after the bow end has left the pressure zone. This makes it possible to compensate for the larger path error when the gripper systems 4, 19 slowed down until the sheet end has left the printing zone. This eliminates the known curl formation on the arch 5. The risk of greasing is also reduced. At the same time the running of the sheet is prevented, in particular towards the end of the sheet on the rubber cylinder, so that the sheet 5 cannot be torn off there in a harmful manner. Tear strips or similar markings in the printed image are thus also reliably prevented.

Damit der vom bedruckten Bogen 5 überdeckte Raum zwischen der vorderen Kante 14 der Abnahmetrommel 2 und den an den Transportketten angeordneten Greifersystemen 4, 19 unmittelbar mit Übergabe des Bogens 5 vom Druckzylinder 1 an die Greifersysteme 4, 19 am Bogenanfang beginnend völlig überbrückbar ist, sind gemäß Figur 2 bis 4 die gekrümmten Stützflächen des Bogenverdrängers 3 entweder als steuer­barer Bogenverdrängerkamm 6 oder als radial verstellbarer Bogenverdrängerkamm 16 und die mit diesen zusammenwirkenden tragenden Flächen des Trommelmantels der Abnahmetrommel 2 ineinandergreifend als Bogenträgerkamm 13 ausgebildet. Durch die Kammanordnung wird verhindert, daß die an den umlaufenden Greifersystemen 4, 19 befestigten Flächen des Bogenverdrängers 3 und die an der umlaufenden Abnahme­trommel 2 befestigten Flächen miteinander beim Einlaufen der Greifersysteme 4, 19 in den Bereich der Abnahmetrommel 2 bzw. beim Verlassen der Abnahmetrommel 2 infolge der vorhandenen Relativgeschwindigkeiten kollidieren. In der gekrümmten Stützfläche des Bogenverdrängers 3 bzw. der Bogenverdrängerkamm 6, 16 und /oder den tragenden Flächen des Trommelmantels der Abnahmetrommel 2 bzw. des Bogenträgerkammes 13 sind für eine abschmierfreie Bogen­führung Elemente 18, z. B. Röllchen vorgesehen. Ebenso sind alle bekannten vergleichbaren Elemente zum Verhindern des Abschmierens einsetzbar, wie z. B. Bogenführungsringe, besondere Oberflächenbeschichtungen, Noppen, Bespannungen mit Super-Blue, Glasperlen oder anderen Aufzügen. Auch der zusätzliche Einsatz von Blasluft oder dergleichen wäre denkbar, ist aber nicht zwingend erforderlich.So that the space covered by the printed sheet 5 between the front edge 14 of the take-up drum 2 and the gripper systems 4, 19 arranged on the transport chains can be completely bridged starting with the transfer of the sheet 5 from the printing cylinder 1 to the gripper systems 4, 19 at the beginning of the sheet, according to Figure 2 to 4, the curved support surfaces of the sheet displacer 3 either as a controllable sheet displacement comb 6 or as a radially adjustable sheet displacement comb 16 and the cooperating supporting surfaces of the drum shell of the take-up drum 2 interlocking as a sheet carrier comb 13. The comb arrangement prevents the surfaces of the sheet displacer 3 fastened to the rotating gripper systems 4, 19 and the surfaces fastened to the rotating take-up drum 2 when the gripper systems 4, 19 enter the area of the take-up drum 2 or collide when leaving the take-up drum 2 due to the relative speeds present. In the curved support surface of the sheet displacer 3 or the sheet displacement comb 6, 16 and / or the load-bearing surfaces of the drum shell of the take-up drum 2 or the sheet support comb 13, elements 18, for. B. rolls are provided. Likewise, all known comparable elements can be used to prevent lubrication, such as. B. sheet guide rings, special surface coatings, knobs, covering with Super Blue, glass beads or other lifts. The additional use of blown air or the like would also be conceivable, but is not absolutely necessary.

Nachdem die Transportketten den Kettenradius der Abnahme­trommel 2 verlassen haben und sich auf einer geraden Weg­strecke weiterbewegen, liegt der Bogenanfang des Bogens 5 weiter satt an der gekrümmten Stützfläche des Bogenverdrängers 3 bzw. der Bogenverdrängerkämme 6, 16 an, so daß eine abschmier- und flatterfreie Bogenführung bis zur Aufhebung des Greiferschlusses im folgenden Druckwerk oder der Bogenauslage gewährleistet ist.After the transport chains have left the chain radius of the take-up drum 2 and continue to travel on a straight path, the beginning of the arc of the arch 5 lies more snugly against the curved support surface of the arch displacer 3 or the arch displacer combs 6, 16, so that a lubrication-free and flutter-free arch guide until the release of the gripper in the following printing unit or the sheet delivery is guaranteed.

Zusammenfassend bestehen die Vorteile der erfindungsgemäßen Lösung darin, daß in einer sehr einfachen und kosten­günstigen Ausführung nach Übergabe des Bogens 5 an die Greifersysteme 4, 19 der Transportketten stets ein gleich­mäßiger Zug durch Bogenverdrängung vom Bogenanfang her aufrechterhalten werden kann, wodurch kein Abschmieren der vorderen Trommelkante zu befürchten ist. Dieser Zug kann durch Heraussteuern des Bogenverdrängers aus dem Ketten­radius auch aufrechterhalten werden, wenn der Bogenanfang bereits auf einer geraden Wegstrecke von den Umlenkketten­rädern langsam abläuft und das Bogenende sich noch in der Druckzone schneller bewegt. Außerdem ist ohne zusätzliche Maßnahmen gewährleistet, daß der Bogen 5 beim weiteren Transport bis zur Aufhebung des Greiferschlusses bei Über­gabe im folgenden Druckwerk oder bei Auslage stets satt an den gekrümmten Stützflächen des Bogenverdrängers 3 bzw. der Bogenverdrängerkämme 6, 16 anliegt, wodurch die bereits angeführte flatterfreie und abschmierfreie Bogenführung auf der gesamten Wegstrecke des in Greifersystemen 4, 19 an Transportketten geführten Bogens 5 ermöglicht wird.In summary, the advantages of the solution according to the invention are that in a very simple and inexpensive embodiment after the sheet 5 has been handed over to the gripper systems 4, 19 of the transport chains, a uniform pull can always be maintained by displacement of the sheet from the beginning of the sheet, as a result of which the front drum edge is not smeared fear. This pull can also be maintained by steering the bend displacer out of the chain radius if the beginning of the bend already runs slowly on a straight path from the deflection sprockets and the end of the bend is still in the Pressure zone moves faster. In addition, it is ensured without additional measures that the sheet 5 always bears tightly against the curved support surfaces of the sheet displacer 3 or the sheet displacement combs 6, 16 during further transport until the removal of the gripper closure upon delivery in the following printing unit or during delivery, whereby the flutter-free combs 6, 16 already mentioned and lubrication-free sheet guidance over the entire path of the sheet 5 guided in gripper systems 4, 19 on transport chains is made possible.
