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.The invention relates to a driver with an essentially stationary roller and a second roller which can be adjusted against it and which is mounted in a swivel frame which can be adjusted by means of a pressure medium cylinder and which is formed from two mutually opposite rockers which are in the region of their common swivel axis by a driver frame on both sides stored base are connected.

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 rigidly connects the rockers together. In order to be able to influence the line of action of the pulling force exerted by the driving, rollers were mounted in chocks which are designed to be adjustable by force. There have also been provided adjustable stops to limit the rocker movement; such adjustment devices, however, require a great deal of effort, since they are acted upon by strong contact forces, for which the desired adjustment devices may also have to be designed. The high level of effort and the rigid design required do not permit the often desired automatic control.

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 object of developing the structure and adjusting drives of a generic driver in such a way that actuating and / or regulating processes can be carried out with simple means.

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 In conjunction with the torsionally designed base, it is possible to effect different pivoting angles of the rockers by means of relatively small differential forces of the positioning means, without the stable mounting of the pivotable roller being impaired.

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 if the controller malfunctions, the resulting incorrect adjustment of 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 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.A driver 1 can be seen in FIG. 1, which has an essentially stationary roller 2 and a roller 3 that can be set against it. The roller 3 is held in a swivel frame 4, which consists of 2 mutually opposite rockers 5, 5 ', which have a common swivel axis 7 in the frame 6 of the driver 1. At the ends of the rockers 5, 5 'opposite the pivot axis 7, pressure medium cylinders 8 are arranged which are pivotably 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 mounted in the frame 6 so as to be pivotable about the pivot axis 7. In the region of the pivot axis 7, the rockers 5, 5 'have a common base 9 which connects the rockers 5, 5' to one another and is formed by a torsion tube 10. The roller 3 is rotatably mounted in the rockers 5, 5 '. The pressure medium cylinders 8, 8 'act on the free ends of the rockers 5, 5'.

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 'to pivot the rockers 5, 5' to different degrees when acted upon differently. However, the torsion tube 10 also ensures the difference in the swiveling range of the rockers 5, 5 'does not exceed a predetermined dimension which is essentially dependent on the rigidity of the torsion tube. By introducing different contact forces with a relatively small differential force of the pressure medium cylinders 8, 8 ', different pivot angles of the rockers 5, 5' and thus of the roller 3 can be brought about. This can be easily influenced by simply pivoting the roller 3, the tensile force exerted by the driver on the belt, so that it does not require much effort to set an optimal tension distribution.
