Description

Die Erfindung betrifft eine Vorrichtung zur Formatverstellung an Bogenführungstrommeln einer Druckmaschine, insbesondere an der Speichertrommel einer Bogenoffsetdruckmaschine für den wahlweisen Schöndruck oder Schön- und Widerdruck, welche die Merkmale der Gattung nach dem Oberbegriff des Patentanspruches 1 aufweist.The invention relates to a device for format adjustment on sheet guide drums of a printing press, in particular on the storage drum of a sheetfed offset printing press for optional face printing or face and back printing, which has the features of the type according to the preamble of claim 1.

Beschrieben und zeichnerisch dargestellt ist eine solche Vorrichtung in der DE-OS 34 10 689 am Beispiel einer Speichertrommel in einer Bogenoffsetdruckmaschine. In solchen Maschinen mit Einrichtungen zur Bogenwendung sind zur genauen Bogenführung viele Elemente erforderlich. Bei der allgemein praktizierten Bogenhinterkantenwendung wird der Bogen vor der Wende auf einer Speichertrommel genau ausgerichtet, gehalten und geglättet. Dazu dienen Glätteinrichtungen aus Saugern oder Greifern bzw. auch aus Saugern und Greifern. Die Lage dieser Glätteinrichtungen gegenüber den Transportgreifern für den Bogen muß auf das Format der zu bearbeitenden Bogen abgestimmt werden und ist daher bei Änderung des Bogenformats und auch bei Umstellung von Schöndruck auf Schön- und Widerdruck zu verstellen, und zwar in der Regel unabhängig von der Umstellung der Transport- und Wendegreifer. Für diese Verstellung sind die Glätteinrichtungen auf einem Tragelement angeordnet, welches auf der Trommelwelle verschwenkbar gelagert und mit dem Trommelkörper in jeder beliebigen Drehlage durch Klemmung verriegelbar ist, so daß bei gelöster Klemmung eine stufenlose Verstellung durchgeführt werden kann.Such a device is described and shown in the drawing in DE-OS 34 10 689 using the example of a storage drum in a sheet-fed offset printing press. In such machines with devices for turning the sheet, many elements are required for precise sheet guidance. In the case of the generally used trailing edge application, the sheet is precisely aligned, held and smoothed on a storage drum before turning. Smoothing devices made of suction cups or grippers or also suction cups and grippers are used for this. The position of these smoothing devices in relation to the transport grippers for the sheet must be matched to the format of the sheet to be processed and is therefore to be adjusted when changing the sheet format and also when changing from straight printing to face and back printing, and as a rule regardless of the change the transport and turning gripper. For this adjustment, the smoothing devices are arranged on a support element which is pivotally mounted on the drum shaft and can be locked with the drum body in any rotational position by clamping, so that when released Clamping can be carried out continuously.

Bei der bekannten Anordnung ist eine Verstellvorrichtung mit einer von außen verdrehbaren Stellwelle vorgesehen, die zentral in einer den Elementen der Klemmung zugeordneten Hohlwelle gelagert ist, die ihrerseits konzentrisch in einer hohl (rohrförmig) ausgebildeten Trommelwelle gelagert ist. An dem nach außen geführten Ende weist die Stellwelle ein Innensechskant auf, so daß eine Verdrehung mit einem entsprechend profilierten Werkzeug vorgenommen werden kann. Mit dem inneren Ende ragt die Stellwelle systembedingt über die halbe Trommelbreite hinaus weit in die Hohlwelle hinein, wobei das hier befestigte Ritzel mit einem in der Hohlwellenwand drehbar gelagerten Zwischenzahnrad kämmt, welches in ein am Tragelement befestigtes Zahnsegment eingreift. Eine solche Verstelleinrichtung ist zwar von außen betätigbar, jedoch kompliziert in der Herstellung und in der Montage. Hohlwellen für die Lagerung der Speichertrommel ergeben eine Schwächung des Trommelwellenzapfens.In the known arrangement, an adjusting device is provided with an externally rotatable adjusting shaft, which is mounted centrally in a hollow shaft assigned to the elements of the clamp, which in turn is mounted concentrically in a hollow (tubular) drum shaft. The actuating shaft has an internal hexagon at the end that leads outwards, so that it can be rotated with a correspondingly profiled tool. With the inner end, the actuating shaft protrudes far beyond the half drum width into the hollow shaft, the pinion attached here meshing with an intermediate gear rotatably mounted in the hollow shaft wall, which meshes with a toothed segment attached to the support element. Such an adjustment device can be operated from the outside, but is complicated to manufacture and assemble. Hollow shafts for the storage of the storage drum result in a weakening of the drum shaft journal.

Aufgabe der Erfindung ist die Gestaltung einer von außen bedienbaren Vorrichtung zur Formatverstellung aus wenigen leicht montierbaren Teilen, die ohne wesentliche Schwächung des Lagerzapfens untergebracht werden kann.The object of the invention is the design of an externally operable device for format adjustment from a few easily assembled parts, which can be accommodated without significant weakening of the bearing journal.

Die Erfindung löst diese Aufgabe durch Ausbildungsmerkmale nach dem Kennzeichen des Anspruches 1 in Verbindung mit einer Vorrichtung nach dem Oberbegriff.The invention solves this problem by training features according to the characterizing part of claim 1 in connection with a device according to the preamble.

Herausragend ist das Merkmal, daß eine kurze dünne Stellwelle in einer Bohrung entsprechend geringen Querschnitts exzentrisch in einem Lagerzapfen der Trommelwelle aus vollem Material vorgesehen ist und mit dem auf dieser Stellwelle befestigten Ritzel unmittelbar in ein Zahnsegment eingreift, welches an der diesem Lagerzapfen benachbarten Stirnseite des Tragelements angeordnet ist. Die für die Lagerung der Stellwelle vorgesehene Bohrung und eine für das Herausführen des Ritzels auf der Stellwelle erforderliche seitliche Ausnehmung in dem Lagerzapfen führen nicht zu einer nennenswerten Schwächung. Auf dem nach außen geführten Ende der Stellwelle ist nach einem weiteren Gedanken zur Ausgestaltung der Erfindung ein weiteres Ritzel befestigt, welches in ein konzentrisch zur Längsachse der Trommelwelle an deren Stirnfläche drehbar gelagert ist. Die Erfindungsmerkmale sind sowohl für die Bedienung der Verstellvorrichtung von Hand als auch für eine motorische Verstellung geeignet. Bei der Bedienung von Hand ist auf dem äußeren Ende der Stellwelle in an sich bekannter Weise ein Sechskant oder dergleichen vorgesehen. Das auf dem äußeren Ende der Stellwelle angeordnete Ritzel greift in diesem Falle in die Innenverzahnung eines konzentrisch zur Längsachse der Trommelwelle drehbar gelagerten Zeigerringes ein, der mit einer festen Formatskala zusammenwirkt. Vorteilhafte Merkmale einer solchen Ausbildung sind in den Unteransprüchen 5 und 6 enthalten.The outstanding feature is that a short, thin control shaft is provided eccentrically in a bore with a correspondingly small cross-section in a bearing journal of the drum shaft made of solid material and engages directly with a toothed segment with the pinion fastened on this control shaft. which is arranged on the end face of the support element adjacent to this bearing journal. The bore provided for the mounting of the actuating shaft and a lateral recess in the bearing journal required for the lead-out of the pinion on the actuating shaft do not lead to any noteworthy weakening. According to a further idea for the embodiment of the invention, a further pinion is fastened on the outwardly directed end of the actuating shaft, which is rotatably mounted in a concentric to the longitudinal axis of the drum shaft on its end face. The features of the invention are suitable for operating the adjusting device by hand as well as for motorized adjustment. When operated by hand, a hexagon or the like is provided on the outer end of the actuating shaft in a manner known per se. In this case, the pinion arranged on the outer end of the actuating shaft engages in the internal toothing of a pointer ring which is rotatably mounted concentrically to the longitudinal axis of the drum shaft and which cooperates with a fixed format scale. Advantageous features of such a training are contained in subclaims 5 and 6.

Bei einer motorisch angetriebenen Vorrichtung zur Formatverstellung greift das auf dem äußeren Ende der Stellwelle angeordnete Ritzel in ein konzentrisch im Lagerzapfen der Trommelwelle drehbar gelagertes und mit einem Stellmotor gekuppeltes Antriebsritzel ein, dessen Gehäuse maschinenfest am Gestell gehalten ist.In a motor-driven device for format adjustment, the pinion arranged on the outer end of the actuating shaft engages in a drive pinion concentrically rotatably mounted in the bearing journal of the drum shaft and coupled to an actuator, the housing of which is held on the frame in a machine-fixed manner.

Auf der Zeichnung ist ein Ausführungsbeispiel für eine von Hand bedienbare und für eine motorisch antreibbare Vorrichtung zur Formatverstellung mit den Erfindungsmerkmalen dargestellt.In the drawing, an embodiment of a manually operated and for a motor-driven device for format adjustment is shown with the features of the invention.

Die Speichertrommel 1 ist mit den Lagerzapfen 2 ihrer Welle 3 aus vollem Werkstoff an beiden Enden in dem Maschinengestell 4 gelagert und durch ein in der Kette der Antriebszahnräder liegendes Zahnrad 5 antreibbar, welches mit der Stirnseite des Lagerzapfens 2 durch Schrauben 6 fest verbunden ist. Am Körper der Speichertrommel 1 sind Bogengreifer 7 in an sich bekannter Weise angeordnet. Gegenüber dem Körper der Speichertrommel 1 ist ein Tragelement 8 um die Längsachse 9 der Trommelwelle 3 im Drehwinkel stufenlos verstellbar und in der eingestellten Lage durch eine auf der Zeichnung nicht wiedergegebene Klemmvorrichtung mit dem Körper der Speichertrommel 1 fest verklemmbar. Als Glätteinrichtung sind in der Figur 2 Saugdüsen 10 beispielweise dargestellt, die in der zwischen dem Tragelement 8 und dem Körper der Speichertrommel 1 axial verlaufenden Grube bzw. dem Trommelkanal den Transportgreifern 7 gegenüberliegend angeordnet sind.The storage drum 1 is supported with the bearing journal 2 of its shaft 3 made of solid material at both ends in the machine frame 4 and can be driven by a gear wheel 5 located in the chain of the drive gearwheels, which is firmly connected to the end face of the bearing journal 2 by screws 6. On the body of the storage drum 1, sheet grippers 7 are arranged in a manner known per se. Compared to the body of the storage drum 1, a support element 8 is infinitely adjustable in the angle of rotation about the longitudinal axis 9 of the drum shaft 3 and, in the set position, can be firmly clamped to the body of the storage drum 1 by a clamping device not shown in the drawing. As a smoothing device, suction nozzles 10 are shown in FIG. 2, for example, which are arranged opposite the transport grippers 7 in the pit or the drum channel running axially between the support element 8 and the body of the storage drum 1.

Der Mechanismus zur Verstellung des Tragelements 8 gegenüber dem Körper der Speichertrommel 1 besteht aus einer Stellwelle 11, die in einer asymmetrisch zur Mittellängsachse 9 parallel zu dieser angeordneten Bohrung des Lagerzapfens 2 drehbar gelagert ist. Das innere Ende dieser Stellwelle 11 trägt ein in einer seitlichen Ausnehmung begrenzter Tiefe drehbares Ritzel 12, welches mit seiner Verzahnung unmittelbar in die innenliegende Verzahnung eines Zahnsegments 13 eingreift, welches an der dem Lagerzapfen 2 benachbarten Stirnseite des Tragelements 8 befestigt ist. Das Zahnsegment 13 erstreckt sich an dem Tragelement 8 über den maximalen Verstellbereich. Das nach außen geführte Ende der Stellwelle 6 durchgreift das Zahnrad 5 und weist im Falle des Beispieles der Figuren 1 bis 3 einen Sechskant 14 auf, der die Verdrehung der Stellwelle 11 mittels eines entsprechend profilierten Werkzeuges ermöglicht. Unterhalb des Sechskants 14 ist auf der Stellwelle 11 ein weiteres Ritzel 15 befestigt, welches mit seiner Verzahnung in die Innenverzahnung eines Zeigerringes 16 eingreift, der konzentrisch zur Mittellängsachse 9 drehbar an der Stirnseite des Lagerzapfens 2 bzw. des Zahnrades 5 gehalten ist. Der Zeigerring 16 weist auf seiner Innenseite einen ringförmigen Ansatz 17 auf, der in eine entsprechend profilierte Ringnut 18 an der Stirnseite des Zahnrades 5 eingreift. Mit seinem Rand hintergreift der Zeigerring 16 kopfartige Verdickungen mehrerer auf dem Umfang verteilt angeordneter Halteschrauben 19. Ein an dem Zeigerring 16 befestigter Zeiger 20 wirkt mit einer an dem Zahnrad 5 ausgebildeten Skala 21 zusammen. Diese Skala ist mit den Bogenformaten abgestimmt, die mit der Maschine bearbeitet werden können. Die durch Verdrehung der Stellwelle 11 mittels des Sechskant 14 erreichte Formateinstellung wird durch den Zeiger 20 auf der Skala 21 angezeigt.The mechanism for adjusting the support element 8 relative to the body of the storage drum 1 consists of a Control shaft 11, which is rotatably mounted in an asymmetrical to the central longitudinal axis 9 parallel to this arranged bore of the bearing pin 2. The inner end of this actuating shaft 11 carries a pinion 12 which is rotatable in a lateral recess and which engages with its toothing directly in the inner toothing of a toothed segment 13 which is fastened to the end face of the support element 8 adjacent to the bearing journal 2. The toothed segment 13 extends on the support element 8 over the maximum adjustment range. The outwardly directed end of the actuating shaft 6 passes through the gear wheel 5 and, in the example of FIGS. 1 to 3, has a hexagon 14 which enables the actuating shaft 11 to be rotated by means of a correspondingly profiled tool. Below the hexagon 14, a further pinion 15 is fixed on the adjusting shaft 11, which engages with its toothing in the inner toothing of a pointer ring 16, which is rotatably held concentrically with the central longitudinal axis 9 on the end face of the bearing journal 2 or the gear wheel 5. The pointer ring 16 has on its inside an annular shoulder 17 which engages in a correspondingly profiled annular groove 18 on the end face of the gear wheel 5. With its edge, the pointer ring 16 engages behind head-like thickenings of a plurality of retaining screws 19 distributed around the circumference. A pointer 20 fastened to the pointer ring 16 interacts with a scale 21 formed on the gear wheel 5. This scale is coordinated with the sheet formats that can be processed with the machine. The format setting achieved by rotating the adjusting shaft 11 by means of the hexagon 14 is indicated by the pointer 20 on the scale 21.

Bei einer motorischen Formatverstellung entfällt die Notwendigkeit der Anzeige des eingestellten Formats. Das auf dem äußeren Ende der Stellwelle 11 angeordnete Ritzel 15 kann somit zur Übertragung der Antriebskräfte genutzt werden. Bei dem Beispiel steht dieses Ritzel 15 mit einem Antriebsritzel 22 in Eingriff, welches konzentrisch zur Mittellängsachse 9 frei drehbar in dem Zahnrad 5 gelagert und mit einem Antriebsmotor 23, zum Beispiel einem elektrischen Antriebsmotor, kuppelbar ist. Im übrigen entspricht die Ausbildung dem Beispiel nach den Figuren 1 bis 3.With a motorized format adjustment there is no need to display the set format. The pinion 15 arranged on the outer end of the adjusting shaft 11 can thus be used to transmit the driving forces. In the example, this pinion 15 is in engagement with a drive pinion 22 which is mounted in the gear wheel 5 so as to be freely rotatable concentrically with the central longitudinal axis 9 and can be coupled to a drive motor 23, for example an electric drive motor. Otherwise, the design corresponds to the example according to FIGS. 1 to 3.
