Description

Die Erfindung betrifft eine Anordnung von Messeinrichtungen für umstellbare Maschinenteile beispielsweise an Bogenführungszylindern in Druckmaschinen, die wahlweise im Schöndruck oder im Schön- und Widerdruck betrieben werden können, wobei beim Umstellen ein System der Maschinenteile zu einem weiteren System hinsichtlich der Phasenlage einstellbar und die Phasenlage der Maschinenteile mess- und auswertbar ist.The invention relates to an arrangement of measuring devices for convertible machine parts for example on sheet guiding cylinders in printing presses, which can be used in straight printing or can be operated in face and reverse printing, whereby when switching a System of machine parts adjustable to another system with regard to the phase position and the phase position of the machine parts can be measured and evaluated.

Umstellbare Bogendruckmaschinen sind allgemein bekannt und wahlweise in den Betriebsarten Schön- oder Schön- und Widerdruck einsetzbar. Das Umstellen bedeutet dabei, dass ein Teil der Druckmaschine gegenüber einem anderen Teil vor oder nach der Wendeeinrichtung verstellt werden muss. Derartige Druckmaschinen weisen daher Kupplungs- und Umstelleinrichtungen auf, vermittels derer der Betriebsartwechsel durchzuführen ist.Convertible sheetfed presses are generally known and optionally in the operating modes Beautiful or beautiful and reverse printing can be used. The changeover means that a part of the printing machine compared to another part before or after the turning device needs to be adjusted. Such printing machines therefore have clutch and Changeover devices, by means of which the mode change is to be carried out.

Die oben dargestellten Umstellvorgänge sind dabei aus der DE 35 26 123 A1 bekannt. Neben dem formatabhängigen Verdrehen der Druckwerke nach der Wendung müssen noch weitere der Wendung dienende Baugruppen formatabhängig umgestellt werden, was aus der oben genannten Schrift ebenfalls bekannt ist.The changeover processes shown above are known from DE 35 26 123 A1. Next the format-dependent turning of the printing units after the turn must still other turnaround modules are converted depending on the format, what from the the above font is also known.

Durch die DE 196 14 818 A1 ist eine Vorrichtung zur Ermittlung einer Winkellage eines ortsveränderlichen Zylinders einer Druckmaschine bekannt.
Gemäß dieser Druckschrift - die Vorrichtung arbeitet mit einem Winkellagegeber - ist ein Stator des Winkellagegebers relativ zum Seitengestell winkelfest angeordnet.DE 196 14 818 A1 discloses a device for determining an angular position of a movable cylinder of a printing press.
According to this document - the device works with an angular position sensor - a stator of the angular position sensor is arranged at a fixed angle relative to the side frame.

Bei umstellbaren, im Schöndruck oder im Schön- und Widerdruck betreibbaren Druckmaschinen, die ein Eintrommelbogenwendesystem aufweisen, erfolgt die Anordnung des Winkelmessgebers (Abtasteinheit) an den Schenkelstirnseiten der zur Wendetrommel benachbarten Druckzylinder. Das entsprechende Referenzmittel (Merkmalgeber) ist fest am Gehäuse (Seitenwand) angeordnet.
An Druckmaschinen, die mit einem Drei-Trommel-Wendesystem arbeiten, sind die Messeinrichtungen an den Trommeln vorgesehen, die vor und nach der Speichertrommel angeordnet sind.In the case of convertible printing machines which can be operated in straight printing or in face and reverse printing and which have a single-drum sheet turning system, the angle encoder (scanning unit) is arranged on the end faces of the leg of the printing cylinder adjacent to the turning drum. The corresponding reference means (feature generator) is fixed on the housing (side wall).
On printing presses that work with a three-drum turning system, the measuring devices are provided on the drums, which are arranged before and after the storage drum.

Nachteilig an diesen Lösungen ist, dass die Montage und die Justage der Messeinrichtung aufwendig ist und durch auftretende Zahnspiele Ungenauigkeiten in den Messergebnissen auftreten. The disadvantage of these solutions is that the assembly and adjustment of the measuring device is complex and due to tooth play inaccuracies in the measurement results occur.

Außerdem ist diese Art der Anordnung der Messeinrichtung sehr teileaufwendig.In addition, this type of arrangement of the measuring device is very expensive.

Aufgabe der Erfindung ist es, eine Anordnung von Messeinrichtungen für umstellbare Maschinenteile in Druckmaschinen zu schaffen, durch die die Messeinrichtung mit einfachen Mitteln montiert und justiert werden kann und genaue und reproduzierbare Messergebnisse liefert.The object of the invention is to provide an arrangement of measuring devices for convertible machine parts to create in printing presses by which the measuring device with simple Means can be assembled and adjusted and accurate and reproducible measurement results supplies.

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

Die Erfindung geht von der Erkenntnis aus, dass mindestens zwei Messeinrichtungen in Tandemanordnung zur Messung der Phasenlage verstellbarer Maschinenteile vorgesehen werden können. Voraussetzung ist, dass koaxial zueinander angeordnete Wellen vorhanden sind, die je mit einem stellbaren System und mit einer Messeinrichtung verbunden sind.
Der Rotor (Merkmalgeber) der Messeinrichtung ist dabei fest einer koaxial gelagerten Welle zugeordnet. Der Stator (Abtasteinheit) der Messeinrichtung ist dabei fest am Gehäuse angeordnet.
Die Vorteile einer derartigen Anordnung der Drehwinkelmesseinrichtung sind, dass mehrere Messeinrichtungen zentrisch über koaxial angeordnete Wellen einem rotierenden oder schwingenden System zugeordnet werden können. Die Ausrichtung der Messeinrichtung ist dadurch einfach zu handhaben und sie kann mit hoher Genauigkeit erfolgen. Der Einstellaufwand ist gering.The invention is based on the knowledge that at least two measuring devices can be provided in tandem for measuring the phase position of adjustable machine parts. The prerequisite is that there are coaxially arranged shafts, each of which is connected to an adjustable system and to a measuring device.

On the other side of the storage drum 2, the rotational angle position measuring device 15 is provided, which has the following structure.
The rotational angle position measuring device 15 consists of a first and second measuring device 23, 24, which are arranged in series one behind the other and have the same structure. The measuring device 23, 24 consists of a housing 19 which is fixedly arranged on a carrier 18 connected to the side wall 7. The housing 19 is loosely mounted on the hollow shaft 6 or on the shaft 13.

Jede Messeinrichtung 23, 24 weist eine Abtasteinheit 20 (Stator) auf, die fest am Gehäuse 19 angeordnet ist. Des Weiteren weisen die Messeinrichtungen 23, 24 einen Merkmalgeber 21 (Rotor) auf, der über eine Scheibe 22 mit der Hohlwelle 6 (erste Messeinrichtung 23) bzw. mit der Welle 13 (zweite Messeinrichtung 24) verbunden ist. Der Merkmalgeber 21 ist mit einer bekannten Kreisteilung mit einer Vielzahl von in radialer Richtung verlaufenden Markierungen auf.
