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
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
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.

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.
