Abstract
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 printing machines.
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.Turning devices working on the principle of three-drum turning consist of three sheet guide cylinders, the middle one as a storage drum with double-large Diameter is formed.
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 enables the bow to be turned on the principle of Trailing edge of sheet and thus the optional application of a face print or a perfecting on the sheet in one 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 bow support systems for the back of the bow, each diametrically are opposite. The sheet holding systems are for processing sheets of different lengths adjustable relative to each other in the circumferential direction.
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 document DE 39 11 630 C2 is an arrangement of sheet holding systems on one Storage drum known. The bow support system for the front area of the bow, the is designed as a clamping gripper, is fixedly arranged on the body of the storage drum. That as Suction cup-shaped bow holding system is provided on a support element which is detachable on Body of the storage drum is arranged.
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 is the support element and thus the suction cups provided on the support element by means of an adjusting shaft, which is mounted in the drum leg, adjustable, on which one end of the control shaft (outside) via a gear stage a motor for actuating the Control shaft and a pinion is arranged at the other end. The pinion engages in a tooth segment a, which is connected to the support member. The control shaft is eccentric in the Drum shaft mounted.
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.It is necessary to relative the sheet holding systems in the circumferential direction of the storage drum to adjust to each other, the control 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 device of the sheet holding systems is the large amount of parts. Many gear elements mesh with one another, which are subject to play, so that the adjustment of the sheet holding systems to the sheet size to be processed is inaccurate.
The drilling and milling 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.DE 39 008 18 C1 shows a sheet guide drum with an inner shaft and one outer drum with at least one with respect to the inner shaft in the circumferential direction adjustable segment. The inner shaft and the outer drum through a multi-plate clutch are coupled with each other, the bow holding systems are assigned.
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 sits between an end face of the segments and a bearing journal Wave. Via an externally operable tension rod and a clamping lever, the Coupling actuated and thus the connection between shaft and segment can be released. Then both can be adjusted relative to each other with the bow support 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 number of parts. The coupling within the storage area of the sheet guide cylinder is difficult to access for maintenance work with wear and soiling. In this case, too, the drilling and milling to weaken the thigh.
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 an arrangement of sheet holding systems on storage drums to create, which ensure a rigid structure of the storage drum and a simple Adjustment of the sheet retention systems guaranteed 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
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 base body of the storage drum by the Side windows connected to the suction system via the driver and the driver pin is, the rigidity of the storage drum base body is not weakened, since the Elongated holes 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 with 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 the gripper and suction system on the storage drum enables to arrange the coupling for the systems outside the storage drum. In order to easy accessibility of the coupling is guaranteed due to the good accessibility.
