Description

Die Erfindung betrifft eine Vorrichtung zur schwingungsarmen Übergabe und zum Transport von Bogen zwischen doppelt großen Druckzylindern einer Mehrfarben-Bogenrotationsoffsetdruckmaschine mittels auf Schienen bewegbarer Greiferwagen nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a device for low-vibration transfer and for transporting sheets between double-sized printing cylinders of a multi-color sheet-fed rotary offset printing machine by means of gripper carriages movable on rails according to the preamble of the first claim.

Bei Mehrfarben-Bogenrotationsoffsetdruckmaschinen mit doppelt großen Druckzylindern, die durch ein Kettenübergabesystem verbunden werden sollen, tritt ein sogenannter Umschlagfehler des jeweils zweiten Bogens auf. Dieser Bogen wird bezogen auf den ersten, früher oder später von doppelt großen Druckzylindern abgenommen oder an den nächstfolgenden doppelt großen Druckzylinder übergeben. Der Umschlagfehler wird bekanntlich durch die Summe von Teilungsfehlern oder andere Fehler der beteiligten Zahnräder des Antriebes verursacht und drückt sich als Vor- bzw. Nacheilung der im ersten Druckwerk auf den Bogen bedruckten Farbe zu den bedruckten Farben der nachfolgenden Druckwerke aus.In multi-color sheet-fed offset printing presses with double-sized printing cylinders that are to be connected by a chain transfer system, a so-called envelope error occurs in the second sheet. This sheet is taken from the first, sooner or later of double-sized impression cylinders or transferred to the next following double-sized impression cylinder. The envelope error is known to be caused by the sum of division errors or other errors of the gearwheels of the drive involved and is expressed as the advance or lag of the color printed on the sheet in the first printing unit to the printed colors of the subsequent printing units.

Zur Lösung dieses Problems ist es bereits aus dem DE-GM 7 512 204 bekannt, den Umschlagfehler mittels justierbarer verzahnter Registerstücke auf doppelt großen Übergabetrommeln dadurch auszugleichen, daß diese zeitweise mit Registerstücken der doppelt großen Druckzylinder kämmen. Bei dieser Vorrichtung handelt es sich aber um ein Trommelübergabesystem, das keine Transportketten aufweist und bei dem keine Greiferwagen auf Schienen bewegbar sind, die über Kulissenverbindungen durch endlose Ketten angetrieben werden müssen. Bedingt durch Toleranzen der Kette oder in den zugeordneten Führungen wird eine schwingungsarme Übergabe bei Kettenförderern in Verbindung mit doppelt großen Kettenradabnahme-bzw. -zuführtrommeln besonders erschwert. Aus der genannten Schrift können somit hierzu keinerlei Hinweise entnommen werden.To solve this problem, it is already known from DE-GM 7 512 204 to compensate for the envelope error by means of adjustable toothed register pieces on double-sized transfer drums by intermeshing them temporarily with register pieces of the double-sized printing cylinders. However, this device is a drum transfer system which has no transport chains and in which no gripper carriages can be moved on rails which have to be driven by endless chains via link connections. Due to tolerances of the chain or in the assigned guides, a low-vibration transfer in chain conveyors in connection with double-large chain wheel removal or. feed drums particularly difficult. No information can be taken from the above-mentioned document.

Aufgabe der Erfindung ist es, bei einer Vorrichtung genannter Art eine registergenaue schwingungsarme Abnahme bzw. Übergabe der zwei Bogen am Umfang des doppelt großen Druckzylinders durch ruhigen und sanften Einlauf der Kurvenrollen der Greiferwagen in die zugeordneten Fanggabeln zu erreichen.The object of the invention is to achieve, in a device of the type mentioned, a register-accurate, low-vibration removal or transfer of the two sheets on the circumference of the double-sized printing cylinder by smooth and gentle entry of the cam rollers of the gripper wagons into the associated catch forks.

Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale des ersten Patentanspruches. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung.The problem is solved by the characterizing features of the first claim. Further developments of the invention result from the subclaims and the description.

Der Vorteil der Erfindung besteht darin, daß erstmalig der Einsatz einer doppelt großen Kettenradabnahme- bzw. -zuführtrommel zur paßgerechten Bogenübergabe zwischen doppelt großen Druckzylindern ermöglicht wird, wodurch die günstigen Eigenschaften von Kettenübergabesystemen wie z.B. weniger Übergaben, geringere Abschmiergefahr und ein weniger häufiges Hin- und Herbiegen der Bogen gegenüber Trommelübergabesystemen bei derartigen Maschinenanordnungen wirksam werden können.The advantage of the invention is that, for the first time, the use of a double-sized sprocket take-off or feed drum for a fitting sheet transfer between double-sized printing cylinders is made possible, whereby the favorable properties of chain transfer systems such as e.g. less transfers, less risk of smearing and less frequent back and forth bending of the sheets compared to drum transfer systems can be effective in such machine arrangements.

Die erfindungsgemäße Vorrichtung bezweckt den Transport und eine registergenaue schwingungsarme Übergabe von Bogen zwischen zwei Druckwerken 1 und 2, die je einen doppelt großen Druckzylinder 3 sowie einfach große Gummizylinder und Plattenzylinder aufweisen. Der Bogentransport erfolgt nach dem Drucken in dem Druckwerk 1 von einer doppelt großen Kettenradabnahmetrommel 4 zur doppelt großen Kettenradzuführtrommel 5 im Druckwerk 2 (s. Fig. 1).The device according to the invention is intended for transport and a register-accurate, low-vibration transfer of sheets between two printing units 1 and 2, each of which has a double-sized printing cylinder 3 and simply large rubber cylinders and plate cylinders. After printing in the printing unit 1, the sheet is transported from a double-size chain wheel take-up drum 4 to the double-size chain wheel supply drum 5 in the printing unit 2 (see FIG. 1).

In Fig. 3 ist die Führung von Greiferwagen 6 im Bereich der Bogenübergabe gezeigt. Die Vorrichtung weist zwei zueinander parallele, endlose Ketten 7 auf, die zur Förderung einer Mehrzahl von Greiferwagen 6 dienen, welche zwischen den Ketten 7 angeordnet sind. Jede Kette 7 läuft über zwei doppelt große Kettenräder 16, die synchron mit den Zylindern der beiden Druckwerke 1 und 2 angetrieben werden.3 shows the guidance of gripper carriages 6 in the area of the sheet transfer. The device has two mutually parallel, endless chains 7, which serve to convey a plurality of gripper carriages 6, which are arranged between the chains 7. Each chain 7 runs over two double-sized chain wheels 16, which are driven synchronously with the cylinders of the two printing units 1 and 2.

Die Greiferwagen 6 sind auf Schienen 8 geführt und werden von den endlosen Ketten 7 angetrieben, wobei jedes Trum der Kette 7 zwischen den doppelt großen Kettenrädern 16 der Kettenradabnahmetrommel 4 und der Kettenradzuführtrommel 5 ebenfalls durch Schienen 29 geführt werden kann. An der Kette 7 greift eine in der Zeichnung nicht dargestellte Antriebsrolle wie ein Kulissenstein in eine nicht dargestellte Kulisse am Greiferwagen 6 mittig zwischen zwei Laufrollen 9 am Greiferwagen 6 ein, welche zwischen den Laufschienen 8 geführt sind. Die doppelt großen Kettenradabnahme- bzw. -zuführtrommeln 4, 5 sind auf der Antriebsseite 24 und der Bedienungsseite 23 in Seitenständern 22 über Lager 25 aufgenommen.The gripper carriages 6 are guided on rails 8 and are driven by the endless chains 7, wherein each strand of the chain 7 between the double-sized chain wheels 16 of the chain wheel removal drum 4 and the chain wheel feed drum 5 can also be guided by rails 29. On the chain 7 a drive roller, not shown in the drawing, engages like a sliding block in a backdrop, not shown, on the gripper carriage 6 in the middle between two rollers 9 on the gripper carriage 6, which are guided between the running rails 8. The double-sized sprocket removal or feed drums 4, 5 are accommodated on the drive side 24 and the operating side 23 in side stands 22 via bearings 25.

Um eine registergenaue schwingungsarme Übergabe der Bogen in Verbindung mit einer Beseitigung des Umschlagfehlers zu erreichen, erfassen die Greiferwagen 6 Fanggabeln 11, 12 an Kurvenrollen 10 und drücken diese nach außen, so daß die Laufrollen 9 der jeweiligen Greiferwagen 6 spielfrei in den Schienen 8 geführt sind. Die Greiferwagen 6 sind dabei im Zweier-Rhythmus durch eine in radialer Richtung mittels einer Höhenverstellung 17 justierbar erste Fanggabel 11 und durch eine in radialer Richtung mittels einer Höhenverstellung 27 justierbare zweite Fanggabel 12 ausrichtbar. Die Fanggabel 11 ist mit einer fest auf der Kettenradwelle 19 der doppelt großen Kettenradabnahme- bzw. -zuführtrommeln 4, 5 angeordneten Halterung 14 verbunden, während die zweite Fanggabel 12 mit einer drehbar zur ersten Fanggabel 11 angeordneten Halterung 15 verbunden ist. Außerdem sind die Fanggabeln 11, 12 mit dem auf der Kettenradwelle 19 in tangentialer Richtung justierbaren doppelt großen Kettenrad 16 stirnseitig lösbar verbunden. Das doppelt große Kettenrad 16 und die zweite Fanggabel 12 lassen sich in tangentialer Richtung mittels derselben Verstellschraube 13 justieren, wobei entweder Verschlußschrauben 26 oder 28 alternativ gelöst werden müssen. Die Verstellschraube 13 ist auf einem Anschlag im doppelt großen Kettenrad 16 abgestützt. Die zweite Fanggabel 12 weist eine ringförmige Aufnahme an der Halterung 15 auf und ist auf dem Flansch der Halterung 14 für die erste Fanggabel 11 gelagert. Der Flansch der Halterung 14 der ersten Fanggabel 11 ist mit der Kettenradwelle 19 durch Stifte 21 fest verbunden. Auf diese Weise sind die Fanggabeln 11, 12 sowohl in radialer Richtung als auch zueinander in Umfangsrichtung justierbar. Außerdem können die Fanggabeln 11, 12 durch eine Fixierung 30 in einer Nullstellung arretiert werden. Dadurch ist es möglich, das doppelt große Kettenrad 16 oder die Fanggabel 12 mit Halterung 15 in tangentialer Richtung unabhängig voneinander zu justieren, derart, daß die Greiferwagen 6 geringfügig nachlaufend mit den Kurvenrollen 10 mit den Einlaufzonen der Fanggabeln 11, 12 in Kontakt kommen, so daß das Kettenspiel in Verbindung mit doppelt großen Kettenradabnahme- bzw. -zuführtrommeln 4, 5 zuverlässig beseitigt und zugleich der Umschlagfehler vermieden werden kann.In order to achieve a precise, low-vibration transfer of the sheets in connection with elimination of the handling error, the gripper carriages 6 capture forks 11, 12 on cam rollers 10 and press them outward, so that the rollers 9 of the respective gripper carriages 6 are guided in the rails 8 without play . The gripper carriages 6 can be aligned in a two-way rhythm by a first catch fork 11 adjustable in the radial direction by means of a height adjustment 17 and by a second catch fork 12 adjustable in the radial direction by means of a height adjustment 27. The catch fork 11 is connected to a holder 14 which is fixedly arranged on the sprocket shaft 19 of the double-sized sprocket take-off or feed drums 4, 5, while the second catch fork 12 is connected to a holder 15 which is rotatable with respect to the first catch fork 11. In addition, the catch forks 11, 12 are detachably connected on the front side to the double-large chain wheel 16 which is adjustable in the tangential direction on the chain wheel shaft 19. The double-sized chain wheel 16 and the second catch fork 12 can be adjusted in the tangential direction by means of the same adjusting screw 13, with either locking screws 26 or 28 alternatively having to be loosened. The adjusting screw 13 is supported on a stop in the double-sized chain wheel 16. The second catch fork 12 has an annular receptacle on the holder 15 and is mounted on the flange of the holder 14 for the first catch fork 11. The flange of the bracket 14 of the first catch fork 11 is firmly connected to the sprocket shaft 19 by pins 21. In this way, the catch forks 11, 12 can be adjusted both in the radial direction and in relation to one another in the circumferential direction. In addition, the catch forks 11, 12 can be locked in a zero position by a fixation 30. This makes it possible to independently adjust the double-sized chain wheel 16 or the catch fork 12 with the holder 15 in the tangential direction in such a way that the gripper carriages 6 come into contact with the cam rollers 10 with the entry zones of the catch forks 11, 12 slightly so that they follow that the chain play in connection with double large sprocket removal or feed drums 4, 5 is reliably eliminated and at the same time the handling error can be avoided.

Zwei gegeneinander gerichtete Keile 18 sind in horizontal verlaufenden Führungen der Halterung 15 der zweiten Fanggabel 12 auf den Flansch der Halterung 14 der ersten Fanggabel 11 abgestützt mittels Justierschrauben 20 verschiebbar angeordnet. Die justierbaren Keile erlauben für eine spielfreie Montage sämtliches Spiel zwischen den einzelnen Sitzen der doppelt großen Kettenräder 16 und der Halterungen 14, 15 der Fanggabeln 11, 12 herauszuziehen und zwar derart, daß eine direkte Abstützung der Fanggabel 11, 12 auf der Kettenradwelle 19 erfolgt.Two mutually directed wedges 18 are arranged in horizontally extending guides of the holder 15 of the second catch fork 12, supported on the flange of the holder 14 of the first catch fork 11, by means of adjusting screws 20. The adjustable wedges allow all play between the individual seats of the double-sized sprockets 16 and the brackets 14, 15 of the catch forks 11, 12 to be pulled out for play-free installation, in such a way that the catch fork 11, 12 is supported directly on the sprocket shaft 19.
