Description

Die Erfindung betrifft eine Anordnung von Bogenhaltesystemen an Speichertrommeln in Wendeeinrichtungen von Bogendruckmaschinen.The invention relates to an arrangement of sheet holding systems on storage drums in turning devices of sheet-fed presses.

Nach dem Prinzip der Drei-Trommel-Wendung arbeitende Wendeeinrichtungen bestehen aus drei Bogenführungszylindern, von denen der mittlere als Speichetrommel mit doppelt-großem Durchmesser ausgebildet ist.According to the principle of the three-drum turn operating turning devices consist of three bow guide cylinders, of which the middle is designed as a double-diameter drum.

Eine derartige Wendeeinrichtung ermöglicht die Wendung des Bogens nach dem Prinzip der Bogenhinterkantenwendung und damit die wahlweise Aufbringung eines Schöndruckes oder eines Schön- und Widerdruckes auf den Bogen in einem Durchlauf.Such a turning device allows the turn of the sheet on the principle of Bogenhinterkantenwendung and thus the optional application of a Perfecting or perfecting on the sheet in a single pass.

Die Speichertrommel weist jeweils zwei Bogenhaltesysteme für den vorderen Bereich und zwei Bogenhaltesysteme für den hinteren Bereich des Bogens auf, die sich jeweils diametral gegenüberliegen. Zur Verarbeitung von Bogen unterschiedlicher Länge, sind die Bogenhaltesysteme in Umfangsrichtung relativ zueinander verstellbar.The storage drum each has two sheet holding systems for the front area and two sheet holding systems for the rear area of the sheet, which are diametrically opposed in each case. For processing sheets of different lengths, the sheet holding systems are circumferentially adjustable relative to each other.

Aus der Druckschrift DE 39 11 630 C2 ist eine Anordnung von Bogenhaltesystemen an einer Speichertrommel bekannt. Das Bogenhaltesystem für den vorderen Bereich des Bogens, das als Klemmgreifer ausgebildet ist, ist fest am Körper der Speichertrommel angeordnet. Das als Sauger ausgebildete Bogenhaltesystem ist an einem Tragelement vorgesehen, das lösbar am Körper der Speichertrommel angeordnet ist.From the publication DE 39 11 630 C2 An arrangement of sheet holding systems on a storage drum is known. The sheet holding system for the front portion of the sheet, which is formed as a clamping gripper, is fixedly arranged on the body of the storage drum. The trained as a sucker sheet holding system is provided on a support member which is detachably arranged on the body of the storage drum.

In Umfangsrichtung ist das Tragelement und damit die am Tragelement vorgesehenen Sauger mittels einer Stellwelle, die im Trommelschenkel gelagert ist, verstellbar, wobei an dem einen Ende der Stellwelle (außen) über eine Zahnradstufe ein Motor zur Betätigung der Stellwelle und am anderen Ende ein Ritzel angeordnet ist. Das Ritzel greift in ein Zahnsegment ein, das mit dem Tragelement verbunden ist. Die Stellwelle ist exzentrisch in der Trommelwelle gelagert.In the circumferential direction, the support element and thus the suction element provided on the support element by means of a control shaft which is mounted in the drum leg, adjustable, wherein at one end of the control shaft (outside) via a gear stage, a motor for actuating the control shaft and arranged at the other end a pinion is. The pinion engages in a toothed segment, which is connected to the support element. The control shaft is mounted eccentrically in the drum shaft.

Ist es erforderlich, die Bogenhaltesysteme in Umfangsrichtung der Speichertrommel relativ zueinander zu verstellen, wird über den Motor und die Zahnradstufe die Stellwelle verdreht, die über das Ritzel und das Zahnsegment auf das Tragelement wirkt. Mit dem Tragelement werden die Sauger relativ zum Klemmgreifer verstellt.If it is necessary to adjust the sheet holding systems in the circumferential direction of the storage drum relative to each other, the adjusting shaft is rotated via the motor and the gear stage, which acts on the support element via the pinion and the toothed segment. With the support element, the suction cups are adjusted relative to the clamping gripper.

Nachteilig an einer derartigen Verstelleinrichtung der Bogenhaltesysteme ist der große Teileaufwand. Es greifen viele Getriebeglieder ineinander, die spielbehaftet sind, so dass die Einstellung der Bogenhaltesysteme auf das zu verarbeitende Bogenmaß ungenau ist.
Die Bohrung und Ausfräsung in der Trommelwelle führt zu einer Schwächung des Trommelschenkels.A disadvantage of such an adjustment of the sheet holding systems is the great amount of effort. There are many gear members in each other, which are game-afflicted, so that the setting of the sheet-holding systems to the processed radians is inaccurate.
The bore and cutout in the drum shaft leads to a weakening of the drum leg.

Die DE 39 008 18 C1 zeigt eine Bogenführungstrommel mit einer inneren Welle und einer äußeren Trommel mit wenigstens einem gegenüber der inneren Welle in Umfangsrichtung verstellbaren Segment. Der inneren Welle und der äußeren Trommel, die durch eine Lamellenkupplung miteinander gekuppelt sind, sind die Bogenhaltesysteme zugeordnet.The DE 39 008 18 C1 shows a sheet guiding drum with an inner shaft and an outer drum with at least one with respect to the inner shaft circumferentially adjustable segment. The inner shaft and the outer drum, which are coupled together by a multi-plate clutch, associated with the sheet holding systems.

Die Kupplung sitzt zwischen einer Stirnfläche der Segmente und einem Lagerzapfen der Welle. Über eine von außen betätigbare Spannstange und einem Klemmhebel kann die Kupplung betätigt und damit die Verbindung zwischen Welle und Segment gelöst werden. Danach sind beide mit den Bogenhaltesystemen relativ zueinander verstellbar.The coupling is seated between an end face of the segments and a journal of the shaft. The clutch can be actuated via an externally actuated tension rod and a clamping lever, thus releasing the connection between shaft and segment. Thereafter, both are adjustable relative to each other with the sheet holding systems.

Nachteilig an dieser Feststell- und Löseeinrichtung ist der große Teileaufwand. Die Kupplung innerhalb der Lagerstelle des Bogenführungszylinders ist schwer zugänglich für Wartungsarbeiten bei Verschleiß und Verschmutzung. Auch in diesem Fall führt die Bohrung und Ausfräsung zu einer Schwächung des Schenkels.A disadvantage of this locking and releasing device is the large parts cost. The coupling within the bearing of the sheet guiding cylinder is difficult to access for maintenance work on wear and contamination. Also in this case, the bore and cutout leads to a weakening of the leg.

Aus der DE 26 32 243 A1 ist eine auf variable Bogenlängen einstellbare Umführtrommel bekannt. Die Umführtrommel weist einen Trommelgrundkörper auf, der auf einer in seitlichen Gestellwänden gelagerten Steckachse befestigt ist. Der Steckachse ist drehbar ein mehrteiliger Hohlkörper zugeordnet, der mit Spannelemente gegenüber dem Trommelgrundkörper verspannt werden kann.From the DE 26 32 243 A1 is known to variable arc length adjustable transfer drum. The transfer drum has a drum base, which is mounted on a mounted in side frame walls through axle. The thru-axle is rotatably associated with a multi-part hollow body, which can be clamped with clamping elements relative to the drum base body.

Die CH 335095 B offenbart einen formatverstellbaren Übertragungszylinder mit einer Hauptwelle die drehbar in seitlichen Gestellwänden gelagert ist. An der Hauptwelle sind Bogenhaltesysteme für die Bogenvorderkanten befestigt. Die Hauptwelle trägt auch Bogenhaltesysteme für die Bogenhinterkante, die mit einer Klemmverbindung gegenüber der Hauptwelle festgelegt sind. Zur Formatverstellung wird die Klemmverbindung gelöst.The CH 335095 B discloses a format-adjustable transfer cylinder with a main shaft which is rotatably mounted in side frame walls. On the main shaft sheet holding systems for the sheet leading edges are attached. The main shaft also carries bow retention systems for the trailing edge of the sheet, which are secured with a clamp connection with respect to the main shaft. For format adjustment, the clamp connection is released.

Aus der DE 43 22 477 A1 ist eine Speichertrommel bekannt, die Bogenhaltesysteme für die Bogenvorder- und Bogenhinterkante trägt, die auf einer Welle gelagert sind und gegeneinander mit fixierbar sind.From the DE 43 22 477 A1 a storage drum is known which carries sheet holding systems for Bogenvorder- and sheet trailing edge, which are mounted on a shaft and against each other with fixable.

Aufgabe der Erfindung ist es, eine Anordnung von Bogenhaltesystemen an Speichertrommeln zu schaffen, die einen steifen Aufbau der Speichertrommel gewährleisten und die eine einfache Verstellung der Bogenhaltesysteme relativ zueinander gewährleistet.The object of the invention is to provide an arrangement of sheet holding systems on storage drums, which ensure a rigid structure of the storage drum and ensures a simple adjustment of the sheet holding systems relative to each other.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention, this object is achieved by the features of the first claim.

Durch die Anordnung einer Zentralachse im Grundkörper der Speichertrommel, die durch die Seitenscheiben über den Mitnehmer und den Mitnehmerbolzen mit dem Saugersystem verbunden ist, wird die Steifigkeit des Speichertrommelgrundkörpers nicht geschwächt, da die Langlöcher auf der Bedienseite der Druckmaschine in der Speichertrommel angeordnet sind. Außerdem ist die Verstellbarkeit der Bogenhaltesysteme mit einfachen Mitteln gewährleistet.By arranging a central axis in the main body of the storage drum, which is connected by the side windows on the driver and the driving pin with the suction system, the rigidity of the storage drum base body is not weakened because the slots are arranged on the operating side of the printing press in the storage drum. In addition, the adjustability of the sheet holding systems is ensured by simple means.

Diese Lagerung und Anordnung von Greifer- und Saugersystem an der Speichertrommel ermöglicht, die Kupplung für die Systeme ausserhalb der Speichertrommel anzuordnen. Damit ist infolge der guten Zugänglichkeit eine einfache Bedienbarkeit der Kupplung gewährleistet.This storage and arrangement of gripper and suction system on the storage drum allows to arrange the coupling for the systems outside the storage drum. This ensures easy operability of the coupling due to the good accessibility.

Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung näher beschrieben werden.Reference to an embodiment, the invention will be described in more detail below.

Fig. 1 shows a schematic representation of a turning device 1 of a three-drum turn in a printing machine and the reversing device 1 upstream and downstream printing cylinder 2,2 'with the blanket cylinder 3,3'.

Die Wendeeinrichtung 1 besteht in Bogenlaufrichtung (durch Pfeil gekennzeichnet) gesehen aus der Übergabetrommel 4 mit einfach-großem Durchmesser, der Speichertrommel 5 mit doppelt-großem Durchmesser und der Wendetrommel 6 mit einfach-großem Durchmesser. Die Speichertrommel 5 ist mit je zwei Bogenhaltesystemen 8, 9 für den Bogen 7 ausgestattet.The turning device 1 consists in the sheet running direction (indicated by arrow) seen from the transfer drum 4 with a single-large diameter, the storage drum 5 with double-large diameter and the beater 6 with a single-large diameter. The storage drum 5 is equipped with two sheet holding systems 8, 9 for the sheet 7.

Die Bogenhaltesysteme 8, 9 für den vorderen Bereich sind als Greifersystem 8 und für den hinteren Bereich als Saugersystem 9 ausgebildet. Greifersystem 8 und Saugersystem 9 sind in Umfangsrichtung zueinander verstellbar, so dass Bogen 7 von max. bis min. Format im vorderen und hinteren Bereich auf der Speichertrommel 5 gehalten werden können. Die Druckzylinder 2,2' weisen einen doppelt-großen Durchmesser auf. Sie können selbstverständlich auch einen einfachgroßen Durchmesser haben.The sheet holding systems 8, 9 for the front area are designed as a gripper system 8 and for the rear area as a suction system 9. Gripper system 8 and suction system 9 are mutually adjustable in the circumferential direction, so that sheet 7 of max. to min. Format in the front and rear of the storage drum 5 can be kept. The printing cylinders 2,2 'have a double-large diameter. Of course, you can also have a single-sized diameter.

Die Greifer- und Saugersysteme 8, 9 liegen in der Speichertrommel 5 sich jeweils diametral gegenüber.The gripper and suction systems 8, 9 are in the storage drum 5 each diametrically opposite.

Der detaillierte Aufbau der Speichertrommel 5 zeigt Fig. 2.The detailed structure of the storage drum 5 shows Fig. 2 ,

In der Seitenwand 10 der Druckmaschine ist der Speichertrommelgrundkörper 11 mit seinen Schenkeln 12 drehbar gelagert. Am Speichertrommelgrundkörper 11 ist das Greifersystem 8 den vorderen Bogensegmenten 13 zugeordnet. In den Schenkeln 12 des Speichertrommelgrundkörpers 11 ist eine Zentralachse 14 drehbar gelagert. Mit der Zentralachse 14 ist innerhalb der Seitenscheiben 17 fest ein Mitnehmer 15 verbunden, der an beiden Enden einen Mitnehmerbolzen 16 aufweist. Anstelle des Mitnehmerbolzens 16 kann auch ein im Querschnitt anderes Element mit dem Mitnehmer 15 verbunden sein.In the side wall 10 of the printing press, the storage drum main body 11 is rotatably mounted with its legs 12. At the storage drum base body 11, the gripper system 8 is assigned to the front arc segments 13. In the legs 12 of the storage drum main body 11, a central axis 14 is rotatably mounted. With the central axis 14, a driver 15 is fixedly connected within the side windows 17, which has a driving pin 16 at both ends. Instead of the driving pin 16 may also be connected in cross section another element with the driver 15.

Der Mitnehmerbolzen 16 geht durch die Seitenscheibe 17 des Speichertrommelgrundkörpers 11. Für den Durchtritt des Mitnehmerbolzens 16 sind in der Seitenscheibe 17 bogenförmige Langlöcher 18 vorgesehen. Die Länge der bogenförmigen Langlöcher 18 entspricht dem erforderlichen Stellweg (max. bis min. Format) der Speichertrommel 5.The driving pin 16 passes through the side plate 17 of the storage drum main body 11. For the passage of the driving pin 16 17 arcuate slots 18 are provided in the side window. The length of the curved elongated holes 18 corresponds to the required travel (maximum to minimum format) of the storage drum 5.

Dem Mitnehmerbolzen 16 ist die Saugertraverse 19 zugeordnet, die das Saugersystem 9 trägt und sich über die Breite der Speichertrommel 5 erstreckt. Die Saugertraverse ist auf den Schenkeln 12 des Speichertrommelgrundkörpers 11 gelagert. Fest mit dem Saugersystem 9 verbunden sind die hinteren Bogensegmente 20.The drive pin 16 is associated with the Saugertraverse 19, which carries the suction system 9 and extends across the width of the storage drum 5. The Saugertraverse is mounted on the legs 12 of the storage drum main body 11. The back arch segments 20 are firmly connected to the nipple system 9.

Im Ausführungsbeispiel ist nur ein Mitnehmer 15 vorgesehen. Es ist jedoch möglich, im Bereich der anderen Seitenscheibe 17 einen weiteren Mitnehmer 15 an der Zentralachse 14 anzuordnen.In the embodiment, only one driver 15 is provided. However, it is possible to arrange a further driver 15 on the central axis 14 in the area of the other side window 17.

Die Klemmvorrichtung an der Speichertrommel 5, mit der Greifer- und Saugersystem 8, 9 miteinander trenn- bzw. verbindbar sind, ist nicht dargestellt.The clamping device on the storage drum 5, with the gripper and suction system 8, 9 separated or connectable with each other is not shown.

Bei Verarbeitung einer anderen Bogenlänge im Schöndruck oder im Schön- und Widerdruck ist die Verstellung der Bogenhaltesystem 8, 9 relativ zueinander notwendig. Dies erfolgt nach Lösen der Klemmvorrichtung durch Drehen der Zentralachse 14 zum Speichertrommelgrundkörper 11. Dafür kann ein separater Motor an der Zentralachse 14 angeordnet werden. Das Greifersystem 8 ist in diesem Fall angebremst.When processing another sheet length in Perfecting or perfecting the adjustment of the sheet holding system 8, 9 relative to each other is necessary. This is done after loosening the clamping device by rotating the central axis 14 to the storage drum main body 11. For this purpose, a separate motor can be arranged on the central axis 14. The gripper system 8 is braked in this case.

Bei Nutzung des Hauptantriebes für die Verstellung wird die Zentralachse 14 angebremst, die nicht dargestellte Klemmvorrichtung gelöst und der Speichertrommelgrundkörper 11, der mit dem Hauptantrieb verbunden ist, und damit das Greifersystem 8 relativ zum Saugersystem 9 verstellt.
Danach werden die Bogenhaltesysteme 8,9 wieder miteinander fest verbunden.
Die Erfindung wurde anhand einer Speichertrommel 5 in einer Wendeeinrichtung 1 beschrieben. Sie ist jedoch auch an Bogenführungszylindern in Schöndruckmaschinen für die Führung des Bogens im hinteren Bereich einsetzbar.When using the main drive for the adjustment, the central axis 14 is braked, the clamping device, not shown, dissolved and the storage drum main body 11, which is connected to the main drive, and thus the gripper system 8 relative to the suction system 9 adjusted.
Thereafter, the sheet holding systems 8,9 are firmly connected again.
