Description
Die Neuerung betrifft inen Antrieb der Zugwalzen von Druckmaschinen.The innovation concerns a drive for the draw rollers of printing machines.
Bei Druckmaschinen werden Zugwalzen verwendet, die zur Papierförderung zwischen den einzelnen Maschinenaggregaten und zur Papierspannungsregulierung dienen. Es sind mechanische Antriebe der Zugwalzen bekannt geworden und zwar werden wahlweise Kegelrädertriebe, Kettentriebe, Riementriebe in Verbindung mit festen Antrieben oder stufsnlosen Regelgetrieber '°rwendet,In printing machines, pull rollers are used, which are used to convey paper between the individual machine units and to regulate the paper tension. There are known mechanical drives of the drawing rollers and indeed optionally bevel gears drives, chain drives, belt drives are used in conjunction with fixed or drives stufsnlosen Regelgetrieber '° r expended
Die Dreh-zahl der Zugvaizen wird immer so bemessen, daß eine gewisse von Zugwalze zu Zugwalze gestufte Voreilung der Zugwalzen gegenüber der Papierbahn vorhanden ist, um der Papierbahn, die zwischen den Zugwalzen und den federnd anliegenden Gumrairollen läuft, den erforderlichen Zug, d. h. die notwendige Papierspannung zu erteilen. Dieser Zug kann durch Veränderung der Anpreßkraft der anliegenden Gummirollen innerhalb geringer Grenzen variiert werden.The speed of the draw roller is always measured in such a way that a certain advance of the draw rolls is stepped from draw roll to draw roll opposite to the paper web is present to the paper web, which is between the draw rollers and the resiliently resting rubber rollers running, the required train, d. H. the necessary paper tension granted. This train can be varied within small limits by changing the contact pressure of the adjacent rubber rollers will.
Die genannte Voreilung bedeutet eine Differenz zwischen der Papierbahnge3chwindigkeit und der Zugwal^enumfangsgeschwindii-,-keit. Der Anpreßdruck der Gummirolle erzeugt infolge derThe above-mentioned advance means a difference between the paper web speed and the peripheral speed of the drawing roll. The contact pressure of the rubber roller generated as a result of

Aus diesem Grund müssen die Zugwalzen bzw. ihre Transportringe bei Bedarf ausge-',li'chselt werden.

For this reason , the pulling rollers or their transport rings must be disengaged, if necessary. However, before one can decide to replace the tension rollers or their rings, certain transport difficulties resulting from wear and tear must be accepted.
Daneben kennt man aber auch den Antrieb mittels Hydraulikmotoren. Uadu.-ch kann der Schlupf zwischen der Papierbahn und den Zugwalzen entfallen. Die Gummirolle ist gegen das Papier und damit gegen die Zugwalze fest angestellt. An den Zugwalzenoberflächen tritt kein nennenswerter Verschleiß auf.In addition , one also knows the drive by means of hydraulic motors. Uadu.-ch can eliminate the slip between the paper web and the draw rollers. The rubber roller is firmly positioned against the paper and thus against the pull roller. There is no significant wear on the pull roller surfaces.
jjie Verwendung· von Hydraulik ist aber in mancher Beziehung nachteilig, besonders sind die Hydraulikleitungen, die Steuerung und die Pumpen aufwendig.However, the use of hydraulics is disadvantageous in some respects, in particular the hydraulic lines, the control and the pumps are complex.

Die Aufgabe ist neuerungsgemäß durch Verwendung von Elektromotoren mit stufenlos regelbarem Drehmoment und regelbarer Drehzahl gelöst.The task is according to the innovation by using electric motors solved with infinitely variable torque and variable speed.
Solche Motoren werden Über Drehstromregelelektronik geregelt.Such motors are controlled by three-phase control electronics.
Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird im folgenden näher erläutert.An exemplary embodiment is shown in the drawings and will be explained in more detail below.
Sie zeigt einen Schnitt durch das Maschinengestell mit einer von einem regelbaren Elektromotor angetriebenen Zugwalzo· In den Seitengestellen I und IX des Maschinenrahmens ist eine Zugwalze mittels Lager 2 und 3 gelagert. Eine Papierbahn h wird durch Gummirollen 5 und 6, die an einer Achse 7 federnd befestigt sind, an die Zugwalze 1 angepreßt. Der Antrieb der Zugwalz« 1 erfolgt durch einen Elektromotor 8, der am Seitengestell II fest angeschraubt und dessen Triebzapfen 9 mittels Paßfeder 10 in einer Bohrung des Lagerzapfens 11 der Zugwalze 1 mit dieser fe^t verbunden ist. Durch eine Leitung 12 wird der Motor 8 mit Strom gespeist. Die Einstellung des Drehmomentes erfolgt durch einen Drehknopf 13, der mit einer in sinem Gehäuse I^ untergebrachten Zwischenschaltung in Verbindung steht, die bewirkt, daß der Elektromotor 8 auf die Papierbahn h stets die gleiche Zugkraft ausübt.It shows a section through the machine frame with a draw roller driven by a controllable electric motor. A draw roller is mounted in the side frames I and IX of the machine frame by means of bearings 2 and 3. A paper web h is pressed against the draw roller 1 by rubber rollers 5 and 6 which are resiliently attached to an axle 7. The pulling roller 1 is driven by an electric motor 8 which is firmly screwed to the side frame II and whose drive pin 9 is connected to the pulling roller 1 by means of a feather key 10 in a bore in the bearing pin 11 of the pulling roller 1. The motor 8 is fed with current through a line 12. The setting of the torque is carried out by a rotary knob 13 which is connected to an intermediate circuit housed in its housing I ^, which causes the electric motor 8 to always exert the same tensile force on the paper web h.
