Abstract

Drive roller in a feeder roll device is connected to a pair of rocker arms (15) each having their own pressure cylinder (8). For feeding metal sheet and strip. The upper roll can be easily adjusted.

Description

Die Erfindung betrifft einen Treiber mit einer im wesentlichen stationär gelagerten Walze und einer gegen diese anstellbaren zweiten Walze, die in einem mittels Druckmittelzylinder verstellbaren Schwenkrahmen gelagert ist, der aus zwei einander gegenüberliegenden Schwingen gebildet wird, die im Bereich ihrer gemeinsamen Schwenkachse durch eine beidseitig im Treiberrahmen gelagerte Basis verbunden sind (siehe z.B. DE-A-26 14 254).The invention relates essentially to a driver stationary roller and an adjustable against this second roller, which is adjustable in a pressure medium cylinder Swing frame is mounted, which consists of two opposite one another Swing is formed in the area of their common Swivel axis through a base mounted on both sides in the driver frame are connected (see e.g. DE-A-26 14 254).

Derartige Treiber weisen eine Basis auf, die die Schwingen starr miteinander verbindet. Um die Wirkungslinie der vom Treiben ausgeübten Zugkraft beeinflussen zu können, hat man Walzen in Einbaustücken gelagert, die kraftbetätigt verstellbar ausgeführt sind. Man hat auch schon zur Begrenzung der Schwingenbewegung verstellbar ausgebildete Anschläge vorgesehen; solche Verstellvorrichtungen jedoch erfordern einen hohen Aufwand, da sie durch starke Auflagekräfte beaufschlagt werden, für die auch ggfs. gewünschte Verstelleinrichtungen auszulegen sind. Der hohe Aufwand und die erforderliche starre Ausführung lassen ein oft gewünschte selbsttätige Regelung nicht zu.Such drivers have a base that makes the wings rigid connects with each other. To the line of action of those exercising To be able to influence tensile force, you have rollers in chocks stored, which are designed to be power-operated adjustable. One has already adjustable to limit the swing arm movement trained stops provided; such adjustment devices however, require a lot of effort because of the strong contact forces be applied, for the adjustment devices that may be required are to be interpreted. The high effort and the necessary rigid execution leave an often desired automatic regulation not to.

Die Erfindung geht daher von der Aufgabe aus, den Aufbau und die Anstellantriebe eines gattungsgemäßen Treibers so weiterzubilden, daß Stell- und/oder Regelvorgänge mit einfachen Mitteln durchführbar sind.The invention is therefore based on the task, the structure and the To further develop the actuators of a generic driver that adjustment and / or control processes can be carried out with simple means are.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die Einleitung unterschiedlicher Anstellkräfte auf die beiden Schwingen erlaubt in Verbindung mit der torsionsfähig ausgeführten Basis unterschiedliche Schwenkwinkel der Schwingen durch relativ geringe Differenzkräfte der Anstellmittel zu bewirken, ohne daß die stabile Halterung auch der schwenkbaren Walze beeinträchtigt ist.This object is solved by the features of claim 1. The Introduction of different contact forces on the two rockers allowed in conjunction with the torsionally designed base different swing angles of the wings due to relatively small To cause differential forces of the adjusting means without the stable Bracket is also affected by the pivotable roller.

Die torsionsfähige Verbindung gewährleistet zudem, daß auch bei einem Fehlverhalten des steuernden die sie ergebende Fehleinstellung der einstellbaren Walze in erträglichen Toleranzen bleibt.The torsional connection also ensures that even a misconduct of the controlling misalignment resulting from it the adjustable roller remains within tolerable tolerances.

Die Erfindung wird anhand einer Zeichnung näher erläutert. Dabei zeigen:

Figur 1
einen erfindungsgemäßen Treiber und
Figur 2
den Schwenkrahmen mit der zweiten Walzen des erfindungsgemäßen Treibers.
The invention is explained in more detail with reference to a drawing. Show:
Figure 1
a driver according to the invention and
Figure 2
the swivel frame with the second roller of the driver according to the invention.

Der Figur 1 ist ein Treiber 1 zu entnehmen, der eine im wesentlichen stationär gelagerte Walze 2 sowie eine gegen diese anstellbare Walze 3 aufweist. Die Walze 3 ist in einem Schwenkrahmen 4 gehalten, welcher aus 2 einander gegenüberliegenden Schwingen 5, 5' besteht, die in dem Rahmen 6 des Treibers 1 eine gemeinsame Schwenkachse 7 aufweisen. An den der Schwenkachse 7 gegenüberliegenden Enden der Schwingen 5, 5' sind Druckmittelzylinder 8 angeordnet, die schwenkbar am Rahmen 6 gehalten sind.FIG. 1 shows a driver 1, which is essentially one stationary roller 2 and a roller that can be set against it 3 has. The roller 3 is held in a swivel frame 4, which consists of 2 opposite wings 5, 5 ', which in the frame 6 of the driver 1 have a common pivot axis 7. At the ends of the pivot axis 7 opposite Swings 5, 5 'are arranged pressure medium cylinders 8 which are pivotable are held on the frame 6.

Der Figur 2 kann entnommen werden, daß die Schwingen 5, 5' im Rahmen 6 um die Schwenkachse 7 verschwenkbar gelagert sind. Im Bereich der Schwenkachse 7 weisen die Schwingen 5, 5' eine gemeinsame, die Schwingen 5, 5' miteinander verbindende Basis 9 auf, die durch ein Torsionsrohr 10 gebildet wird. Die Walze 3 ist in den Schwingen 5, 5' drehbar gelagert. An den freien Enden der Schwingen 5, 5' greifen die Druckmittelzylinder 8, 8' an. It can be seen from FIG. 2 that the rockers 5, 5 'are in the frame 6 are pivotally mounted about the pivot axis 7. In the field of Swing axis 7, the wings 5, 5 'have a common Swing 5, 5 'interconnecting base 9 by a Torsion tube 10 is formed. The roller 3 is in the wings 5, 5 'rotatably mounted. Grab at the free ends of the wings 5, 5 ' the pressure medium cylinders 8, 8 '.

Das Torsionsrohr 10 erlaubt, daß die Druckmittelzylinder 8, 8' bei unterschiedlich starker Beaufschlagung die Schwingen 5, 5' auch unterschiedlich stark verschwenken. Das Torsionsrohr 10 gewährleistet aber auch der Unterschied im Schwenkbereich der Schwingen 5, 5' ein vorgegebenes und im wesentlichen von der Steifheit des Torsionsrohr abhängiges Maß nicht überschreitet. Durch Einleitung unterschiedlicher Anstellkräfte bei relativ geringer Differenzkraft der Druckmittelzylinder 8, 8' lassen sich unterschiedliche Schwenkwinkel der Schwingen 5, 5' und damit der Walze 3 bewirken. Damit läßt sich durch einfaches Verschwenken der Walze 3 die vom Treiber ausgeübte Zugkraft auf das Band leicht beeinflussen, so daß es keines großen Aufwandes bedarf, um eine optimale Zugverteilung einzustellen. The torsion tube 10 allows the pressure medium cylinders 8, 8 'at the swing 5, 5 'also act differently swivel to different degrees. The torsion tube 10 ensures but also the difference in the swing range of the wings 5, 5 'a predetermined and essentially of the stiffness of the Torsion tube dependent dimension does not exceed. By introduction different contact forces with a relatively low differential force the pressure medium cylinders 8, 8 'can have different swivel angles the swing 5, 5 'and thus the roller 3 cause. In order to can by simply pivoting the roller 3 by the driver slightly exerted pulling force on the belt so that it no great effort is required to optimally distribute trains adjust.
