Description

Die Erfindung betrifft eine Vorrichtung zur Korrektur des Schnittregisters nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for correcting the cutting register according to the preamble of claim 1.

Es ist bekannt (z. B. DE-PS 542 670), daß verschiedene bedruckte Bahnen jeweils über eine verstellbare Papierleitwalze schnittregistergerecht einem Falzapparat zur gemeinsamen Weiterverarbeitung zugeleitet werden. Das Schnittregister wird dabei für jede einzelne Bahn durch eine entsprechende Bahnlängenkorrektur über die jeweilige verstellbare Papierleitwalze eingestellt.It is known (e.g. DE-PS 542 670) that various printed webs are each fed to a folder for joint further processing in accordance with the cutting register via an adjustable paper guide roller. The cutting register is set for each individual web by a corresponding web length correction using the respective adjustable paper guide roller.

Die DE-PS 36 02 894 entwickelt die beschriebene Lösung im Sinne einer Automatisierung des Verstellvorganges während des Maschinenlaufes weiter.DE-PS 36 02 894 further develops the solution described in terms of automating the adjustment process while the machine is running.

Der Nachteil dieser Lösungen ist, daß sich z. B. die auf das Schnittregister auswirkende Verstellung des Vorfalzes im Falzapparat auf Grund einer Veränderung der Phasenlage des Messerzylinders und sich im gleichen Sinne auswirkende Verdrehungen von Antriebselementen im Falzapparat sowie Produktverlagerungen während des Falzvorganges infolge dynamischer Belastungen nur für jede einzelne Bahn kompensieren lassen. Der dafür erforderliche manuelle bzw. technische Aufwand ist erheblich.The disadvantage of these solutions is that z. For example, the adjustment of the pre-fold in the folder due to a change in the phase position of the knife cylinder and the twisting of drive elements in the folder as well as product displacements during the folding process due to dynamic loads can only be compensated for each individual web. The manual or technical effort required for this is considerable.

Andererseits sind technische Mittel bekannt (z. B. DE-AS 12 76 658), die ein registergerechtes Einkuppeln des Falzapparates in den Antrieb für die Druckwerke, jedoch keine stufenlose Korrektur des Schnittregisters des Falzapparates während des Maschinenlaufes gestatten.On the other hand, technical means are known (e.g. DE-AS 12 76 658) which allow the folder to be coupled into the drive for the printing units in a register-correct manner, but do not permit continuous correction of the cutting register of the folder during machine operation.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Korrektur des Schnittregisters gemäß dem Oberbegriff von Anspruch 1 zu schaffen, mit der mit einfachen technischen, wenig Verstellaufwand erfordernden Mitteln sich vom Falzapparat auf das Schnittregister aller bedruckter Bahnen gleichermaßen auswirkende Veränderungen während des Maschinenlaufes kompensiert werden können.The invention has for its object to provide a device for correcting the cutting register according to the preamble of claim 1, with the simple technical means requiring little adjustment effort from the folder on the cutting register of all printed webs equally effective changes during machine operation can be compensated .

Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is solved by the characterizing features of claim 1.

In den Unteransprüchen sind verschiedene erfindungsgemäße Lösungsvarianten sowie deren vorteilhafte Ausgestaltungen wiedergegeben, die ohne größeren Aufwand mit einfachen technischen Mitteln vorzunehmen sind.Various subclaims according to the invention are in the subclaims Solution variants and their advantageous embodiments are reproduced, which can be carried out with simple technical means without great effort.

Bis auf den Zahnriemen- bzw. Kettentrieb können alle Lösungen bei entsprechender konstruktiver Gestaltung zusätzlich als Kupplung für den Falzapparatantrieb genutzt werden.Except for the toothed belt or chain drive, all solutions can also be used as a coupling for the folder drive with the appropriate design.

Fig. 1 zeigt im schematischer Darstellung die Antriebsverbindung eines Druckwerkes 1 mit dem Falzapparat 2 einer Rotationsdruckmaschine über eine Längswelle 3 und einen Zahnriementrieb 4.1 shows a schematic illustration of the drive connection of a printing unit 1 to the folder 2 of a rotary printing press via a longitudinal shaft 3 and a toothed belt drive 4.

Der Falzapparat 2 enthält als funktionell zusammengehörige Zylindergruppe einen Messerzylinder 5, einen Punktur-Falzmesserzylinder, verkürzt Falzzylinder 6 genannt, und einen Falzklappenzylinder 7.The folder 2 contains, as a functionally associated cylinder group, a knife cylinder 5, a puncture folder cylinder, shortened called the folding cylinder 6, and a folder cylinder 7.

Zur Falzverstellung oder Vorfalzverstellung wird das die Falzklappen 8 tragende Zylinderteil 9 des Falzzylinders 6 mit dem Falzklappenzylinder 7 bzw. das die Punkturen 10 tragende Zylinderteil 11 des Falzzylinders 6 mit dem Messerzylinder 5 verdreht, wobei jeweils ein mit dem die Falzklappen 8 tragenden Zylinderteil 9 des Falzzylinders 6 verbundenes, mit dem Antriebszahnrad 12 des Falzklappenzylinders 7 im Eingriff stehendes Zahnrad 13 gegenüber einem koaxialen, mit dem die Punkturen 10 tragenden Zylinderteil 11 des Falzzylinders 6 verbunden, in das Antriebsrad 14 des Messerzylinders 5 eingreifenden Zahnrad 15 verdreht wird, wozu eine zwischen beiden Zahnrädern 13; 15 bestehende feste Verbindung, z. B. in Form einer kraftschlüssigen Schraubenverbindung 16, beider Radkörper vorher zu lösen ist.For the folding adjustment or pre-folding adjustment, the cylinder part 9 of the folding cylinder 6 carrying the folding jaws 8 is rotated with the folding jaw cylinder 7 or the cylinder part 11 of the folding cylinder 6 bearing the punctures 10 is rotated with the knife cylinder 5, one cylinder part 9 of the folding cylinder each carrying the folding jaws 8 6 connected, with the drive gear 12 of the jaw cylinder 7 meshing gear 13 with respect to a coaxial, with which the punctures 10 supporting cylinder part 11 of the folding cylinder 6 is connected, in the drive wheel 14 of the knife cylinder 5 engaging gear 15 is rotated, for which purpose between the two gears 13; 15 existing fixed connection, for. B. in the form of a non-positive screw connection 16, both wheel body to be solved beforehand.

Durch die geschilderte Vorfalz- bzw. Falzverstellung wird zwangsläufig der Satzspiegel gegenüber dem durch die Zylindergruppe erzeugten Querfalz verlagert, was bisher durch eine Schnittregisterverstellung in Form einer Veränderung der Einzelbahnenlängen zwischen den Druckwerken und den Falztrichtereinlauf in den Falzapparat 2 korrigiert wurde.Due to the pre-fold or fold adjustment described, the type area is inevitably shifted relative to the transverse fold generated by the cylinder group, which was previously the result of an adjustment of the cut register in the form of a change in the individual web lengths between the printing units and the Corrector inlet in folder 2 was corrected.

Die Erfindung löst diese Aufgabe durch eine Summenschnittkorrektur mit Hilfe eines in den Antrieb vom Falzapparat 2 eingefügten, die Winkellage zwischen Ein- und Abtrieb stufenlos während des Maschinenlaufes verstellbaren Korrekturgliedes.The invention solves this problem by means of a total cut correction with the aid of a correction element which is inserted into the drive from the folder 2 and which can be used to adjust the angular position between the input and the output steplessly while the machine is running.

Das dazu in Fig. 1 strichpunktiert gekennzeichnete, am Anfang der Zahnradkette 17 für den Antrieb der Zylindergruppe angeordnete Korrekturglied K ist in Fig. 2 detailliert dargestellt.Correction element K, indicated by dash-dotted lines in FIG. 1 and arranged at the beginning of gear chain 17 for driving the cylinder group, is shown in detail in FIG. 2.

Dabei ist auf einer durchgehenden, im Maschinengestell gelagerten Welle 18 (Fig. 1) ein zweiteiliges Doppelzahnrad 19 (Fig. 2) drehbar gelagert, daß ein in ein Zahnrad 20 der Zahnradkette 17 (Fig. 1) eingreifendes außenverzahntes Teil 21 und ein mit letzterem verschraubtes weiteres Teil 22 besitzt, in dessen wahlweise links- oder rechtssteigende, wie in zugeordneten kleinen Kreisen in Fig. 2 symbolhaft dargestellt, Innenverzahnung ein auf einen Zapfen der Welle 18 verschiebbar angeordnetes Ritzel 23 eingreift, in dem stirnseitig koaxial eine in einer Gewindebohrung 24 eines über Stehbolzen 25 mit dem Maschinengestell 26 verbundenen Teiles 27 geführte Stellspindel 28 drehbar gelagert ist, die mittels Handrad 29 längsverstellbar und durch einen Klemmring 30 gegenüber dem Maschinengestell 26 arretierbar ist.Here, on a continuous shaft 18 mounted in the machine frame (FIG. 1), a two-part double gear 19 (FIG. 2) is rotatably mounted that an externally toothed part 21 engaging in a gear 20 of the gear chain 17 (FIG. 1) and a part 21 with the latter screwed further part 22 has, in the optionally left or right-rising, as symbolically shown in associated small circles in Fig. 2, engages a pinion 23 slidably arranged on a pin of the shaft 18, in the front coaxially one in a threaded bore 24 one Adjusting spindle 28, which is guided by means of stud bolts 25 connected to machine frame 26, is rotatably mounted, which can be adjusted longitudinally by means of handwheel 29 and locked against machine frame 26 by a clamping ring 30.

Durch eine axiale Verschiebung des Ritzels 23 kommt es infolge der Schrägverzahnung zwangsläufig zu einer Verdrehung der Welle 18 gegenüber der nachfolgenden Zahnradkette 17 (Fig. 1) des Falzapparatantriebes.An axial displacement of the pinion 23 inevitably results in the shaft 18 being rotated relative to the following gear chain 17 (FIG. 1) of the folder drive as a result of the helical teeth.

Das Korrekturglied K kann neben der Verstellung der Phasenlage zur Summenschnittkorrektur der Bahnen zusätzlich als Kupplung des Falzapparatantriebes genutzt werden, indem das Ritzel 23 von dem innenverzahnten Teil des Doppelzahnrades 19 bis zur Bildung eines Spaltes X zwischen beiden entkuppelt wird.The correction element K can be used in addition to the adjustment of the phase position for total cross-section correction of the webs additionally as a coupling of the folder drive, in that the pinion 23 is uncoupled from the internally toothed part of the double gear wheel 19 until a gap X is formed between the two.

Das registergerechte Einkuppeln kann im Maschinenstillstand über Marken an den Kuppelteilen einfach realisiert und das exakte Schnittregister über eine den Verstellweg der Stellspindel 28 anzeigende Skala reproduzierbar eingestellt werden.When the machine is at a standstill, register engagement can be easily achieved using marks on the coupling parts and the exact cutting register can be reproducibly set using a scale that shows the adjustment path of the adjusting spindle 28.

Fig. 3 zeigt als Variante ein Korrekturglied KI, das aus zwei auf einem im Maschinengestell 26I befestigten Bolzen 31 koaxial drehbar gelagerten Doppelzahnrädern 32; 33 besteht, deren in axialer Richtung jeweils außen liegende Zahnkränze 34; 35 mit je einem Zahnrad 36; 37 des Falzapparatantriebes im Eingriff stehen, und deren innen einander benachbarte Zahnkränze 38; 39 mit Verzahnungen unterschiedlicher Steigung, wie wiederum in den beigeordneten Kreisen in Fig. 3 symbolhaft dargestellt, ausgestattet sind, in die jeweils die Innenverzahnungen eines übergreifenden Schiebezahnrades 40 getrennt eingreifen.FIG. 3 shows a variant of a correction element K I , which consists of two double gears 32 coaxially rotatably mounted on a bolt 31 fastened in the machine frame 26 I ; 33 exists, the ring gears 34; 35, each with a gear 36; 37 of the folder drive are engaged, and their internally adjacent toothed rings 38; 39 are equipped with toothings of different pitch, as again symbolically shown in the associated circles in FIG. 3, in which the inner toothings of an overlapping sliding gearwheel 40 engage separately.

Auf einer zu den Doppelzahnrädern 32; 33 achsparallel in einer Gewindebohrung 41 eines Teils des Maschinengestells geführten Stellspindel 42 ist ein in eine ringförmige Aussparung 43 des Umfanges des Schiebezahnrades 40 eingreifender Mitnehmer 44 befestigt, über den mit Hilfe der Stellspindel 42 das Schiebezahnrad 40 während des Maschinenlaufes und damit unter gleichzeitiger Verdrehung der Doppelzahnräder 32; 33 zueinander axial verschoben werden kann.On one of the double gears 32; 33 An adjusting spindle 42, which is guided axially parallel in a threaded bore 41 of a part of the machine frame, is a driver 44 engaging in an annular recess 43 in the circumference of the sliding gear 40 attached, by means of the adjusting spindle 42, the sliding gear 40 during machine operation and thus with simultaneous rotation of the double gears 32; 33 can be moved axially to each other.

Auch das Korrekturglied KI gemäß Fig. 3 kann zusätzlich als Kupplung für den Falzapparatantrieb mit genutzt werden. Zum Entkuppeln muß dabei das Schiebezahnrad 40 mindestens bis zum Außereingriff von einem der Doppelzahnräder 32; 33 und einen sich bildenden Spalt XI zwischen den zu entkuppelnden Teilen axial verschoben werden.The correction element K I according to FIG. 3 can also be used as a clutch for the folder drive. For decoupling, the sliding gear 40 must at least until one of the double gears 32; 33 and a gap X I which forms between the parts to be uncoupled are axially displaced.

Dabei können analog zu Fig. 2 an dem Schiebezahnrad 40 und den Doppelzahnrädern 32; 33 als Hilfe für das registergerechte Wiedereinkuppeln Markierungen und an der Stellspindel 42 für die Summenschnittkorrektur aller Bahnen eine Skala angebracht werden.Analogously to FIG. 2, the sliding gear 40 and the double gears 32; 33 as an aid for register-correct recoupling and a scale on the adjusting spindle 42 for the total cut correction of all tracks.

Das Korrekturglied KI kann in Fig. 1 an der Stelle des Zahnrades 20 der Zahnradkette 17 des Falzapparatantriebes plaziert werden, wobei beispielsweise das Zahnrad 37 auf der Welle 18 angeordnet sein und das Zahnrad 36 unmittelbar als Antriebszahnrad für den Messerzylinder 5 dienen kann.The correction element K I can be placed in Fig. 1 at the location of the gear 20 of the gear chain 17 of the folder drive, for example the gear 37 being arranged on the shaft 18 and the gear 36 serving directly as the drive gear for the knife cylinder 5.

Als weitere Variante zeigt Fig. 4 ein Korrekturglied KII mit einem das Zahnrad 20 in Fig. 1 ersetzenden, auf einer Büchse 45 drehbar gelagerten Doppelzwischenrad 46, das mit einer Außenverzahnung in ein auf der durchgehenden Welle 18 von Fig. 1 angeordnetes Ritzel 47 und mit seiner anderen, von ersteren in der Steigung abweichenden Außenverzahnung in ein Zahnrad 48 der Zahnradkette des Falzklappenantriebes, beispielsweise in das Antriebszahnrad 14 des Messerzylinders 5 von Fig. 1, eingreift.As a further variant, FIG. 4 shows a correction element K II with a double intermediate gear 46, which replaces the gear 20 in FIG. 1 and is rotatably mounted on a bush 45, which has external teeth in a pinion 47 and arranged on the continuous shaft 18 from FIG with its other external toothing which deviates from the former, engages in a gear 48 of the gear chain of the jaw drive, for example in the drive gear 14 of the knife cylinder 5 of FIG. 1.

Die Büchse 45 ist axial verschiebbar auf einem im Maschinengestell 26II befestigten Bolzen 49 angeordnet. Letzterer sowie die Büchse 45 besitzen jeweils stirnseitig koaxiale Gewindebohrungen 50; 51 unterschiedlicher Steigung, in denen eine ein Handrad 52 tragende, mit Differenzgewinde ausgestattete Stellspindel 55 eingreift bzw. geführt wird.The bush 45 is arranged axially displaceably on a bolt 49 fastened in the machine frame 26 II . The latter and the bush 45 each have coaxial threaded bores 50 on the end face; 51 of different pitch, in which an adjusting spindle 55 carrying a handwheel 52 and equipped with a differential thread engages or is guided.

Bei axialer Verschiebung des Doppelzwischenrades 46 infolge Verdrehung der Stellspindel 52 wird auf Grund der unterschiedlichen Steigungen der Verzahnungen das Zahnrad 48 gegenüber dem Ritzel 47 verdreht und somit die gewünschte Längenkorrektur aller Bahnen zwischen den Druckwerken und dem Falzapparat erreicht.When the double idler gear 46 is axially displaced as a result of rotation of the adjusting spindle 52, the gear 48 is rotated relative to the pinion 47 due to the different pitches of the toothings, and the desired length correction of all webs between the printing units and the folder is thus achieved.

Auch das Doppelzwischenrad 46 kann zusätzlich als Kupplung genutzt werden, indem durch entsprechende Gestaltung abgesichert wird, daß es mit einer seiner Verzahnungen von dem entsprechenden Gegenrad außer Eingriff bringbar ist, wie in Fig. 4 durch den entstehenden Spalt XII angedeutet.The double idler gear 46 can also be used as a clutch by ensuring that it can be disengaged from the corresponding counter gear by one of its toothings, as indicated in FIG. 4 by the gap X II .

Auch bei Fig. 4 sind die bereits bei Fig. 2 und 3 beschriebenen Hilfsmittel für das registergerechte Einkuppeln und eine reproduzierbare Summenschnittkorrektur anwendbar.Also in FIG. 4, the aids already described in FIGS. 2 and 3 for register-correct engagement and a reproducible total cut correction can be used.

Fig. 5 zeigt den Zahnriementrieb 4 in Blickrichtung A von Fig. 1 in einer als Korrekturglied KIII aller Bahnen geeigneten Art und Weise, wobei die bereits beschriebenen gleichwirkenden Mittel gemäß Fig. 2 bis 4 auf der anderen Antriebsseite des Falzapparatantriebes entfallen können.FIG. 5 shows the toothed belt drive 4 in the direction of view A of FIG. 1 in a manner suitable as a correction element K III of all tracks and Way, the previously described equivalent means according to FIGS. 2 to 4 on the other drive side of the folder drive can be omitted.

Zwischen der auf der Längswelle 3 angeordneten Zahnscheibe 54 und der Zahnscheibe 55 der Welle 18 (Fig. 1) ist ein zu den beiden Trumen 56; 57 quer verschiebbarer Schlitten 58 angeordnet (Fig. 5), der für jedes Trum 56; 57 jeweils eine diese seitlich auslenkende Zahnscheibe 59; 60 besitzt.Between the toothed disk 54 arranged on the longitudinal shaft 3 and the toothed disk 55 of the shaft 18 (FIG. 1), one to the two runs 56; 57 arranged transversely displaceable carriage 58 (Fig. 5) which for each strand 56; 57 each have a toothed pulley 59; 60 owns.

Zur Richtungsänderung der Trume 56; 57 in Verschieberichtung des Schlittens 58 sind jeweils im Maschinengestell drehbar gelagerte Zahnscheiben 61; 62; 63; 64 vorgesehen, die mit je einer koaxialen Führungsrolle 65; 66; 67; 68 für den Schlitten 58 zusätzlich ausgestattet sind.To change the direction of the dreams 56; 57 in the direction of displacement of the carriage 58 are each toothed disks 61 rotatably mounted in the machine frame; 62; 63; 64 provided, each with a coaxial guide roller 65; 66; 67; 68 are additionally equipped for the slide 58.

Letzterer besitzt stirnseitig eine Gewindebohrung 69, in die eine mit Differenzgewinde ausgestattete, in einer weiteren Gewindebohrung 70 des Maschinengestells 26III in Verschieberichtung des Schlittens 58 geführte, mittels eines nicht dargestellten Handrades betätigte Stellspindel eingreift.The latter has a threaded bore 69 on the end face, in which an adjusting spindle, which is equipped with a differential thread and is guided in a further threaded bore 70 of the machine frame 26 III in the direction of displacement of the slide 58 and is actuated by means of a handwheel, not shown, engages.

Mit einer Verschiebung des Schlittens 58 wird durch eine Längenänderung des treibenden Trums 56 in Verbindung mit einem entsprechenden Längenausgleich für das andere Trum 57 die Winkellage zwischen de in den Falzapparatantrieb integrierten beiden Zahnscheiben 54; 55 verändert und damit die gewünschte Bahnlängenkorrektur herbeigeführt.When the carriage 58 is displaced, the angular position between the two toothed disks 54 integrated into the folder drive is changed by changing the length of the driving run 56 in conjunction with a corresponding length compensation for the other run 57. 55 changed and thus brought about the desired path length correction.

Auch die Stellspindel 71 des Zahnriementriebes kann mit einer die Einstellbarkeit erleichternden Skala ausgerüstet werden.The adjusting spindle 71 of the toothed belt drive can also be equipped with a scale that makes it easier to adjust.

Abschließend sei noch darauf verwiesen, daß die kuppelbaren Zahnräder gemäß Fig. 2 bis 4 wahlweise mit das Ansetzen eines Werkzeuges ermöglichenden Formelementen ausgestattet werden können.In conclusion, it should also be pointed out that the detachable gear wheels according to FIGS. 2 to 4 can optionally be equipped with shaped elements which enable a tool to be attached.
