Description

In der Zeichnung ist eine Zettelwalzenvorrichtung gemäß der Erfindung beispielsweise dargestellt. Es zeigtIn the drawing, a slip roller device according to the invention is shown for example. It shows

Fig. 1 eine Draufsicht auf die Zettelwalzenvorrichtung, F i g. 2 einen senkrechten Axialteilschnitt,1 shows a plan view of the slip roller device, FIG. 2 a vertical partial axial section,

F i g. 3 eine Seitenansicht des Ständers,F i g. 3 is a side view of the stand,

F i g. 4 einen senkrechten Schnitt durch eine Zettelwalze mit einer Zettelscheibe.F i g. 4 shows a vertical section through a slip roller with a slip disk.

Die vorzugsweise aus Grauguß bestehende Zettelwalze ist in ihrer Mitte in zwei Teilwalzen 1, 2 unterteilt, die an ihren äußeren Enden mit Zapfen 3 in Lagern 4 gelagert sind, wobei die die Zapfen 3 aufnehmenden Lagerschalen in an sich bekannter Weise um eine senkrechte Achse drehbar sind.The slip roll, which is preferably made of gray cast iron, is divided in its middle into two partial rolls 1, 2, which are mounted at their outer ends with pins 3 in bearings 4, the pins 3 receiving Bearing shells are rotatable about a vertical axis in a manner known per se.

Auf den Zapfen 3 sitzen fest Schneckenräder 5, die je von einer Schnecke 6 antreibbar sind. Wie der rechte Teil der F i g. 1 zeigt, tritt das Schneckenrad 5 der Teilwalze 2 vorübergehend außer Eingriff mit der zugeordneten Schnecke 6, wenn die Teilwalze aus ihrer Arbeitsstellung herausgeschwenkt wird. Die Schnecken 6 sitzen fest auf Wellen 7, von denen eine die Hauptantriebswelle für die Teilwalzen 1, 2 ist. Zur Erzielung eines synchronen Antriebs der beiden Teilwalzen 1, 2 tragen die Wellen 7 je ein Kegelrad 8, mit denen je ein Kegelrad 9 im Eingriff steht. Die beiden Kegelräder 9 sind durch eine Welle 10 miteinander verbunden, die in Lagern 11 gelagert ist, die auf Konsolen 24 der Stuhlung 23 der Zettelwalzenvorrichtung angeordnet sind (F i g. 1 und 3).Worm wheels 5, each of which can be driven by a screw 6, are firmly seated on the pin 3. Again right part of FIG. 1 shows, the worm wheel 5 of the partial roller 2 temporarily disengages with it the associated screw 6 when the part-roller is pivoted out of its working position. the Screws 6 sit tightly on shafts 7, one of which is the main drive shaft for the partial rollers 1, 2. To achieve a synchronous drive of the two partial rollers 1, 2, the shafts 7 each carry a bevel gear 8, with each of which a bevel gear 9 is in engagement. The two bevel gears 9 are supported by a shaft 10 connected to each other, which is stored in bearings 11, which are on consoles 24 of the frame 23 of the slip roller device are arranged (Fig. 1 and 3).

Die einander zugekehrten Stirnseiten 12, 13 der Teilwalzen 1, 2 sind in einem Abstand a (Fig. 2) voneinander angeordnet. In dem durch diesen Abstand α gegebenen Zwischenraum 14 sind Lager 15, 16 angeordnet, die von einem scheibenartigen Stander 17 getragen sind, der aus dem Zwischenraum 14 herausragt. Der Ständer 17 weist sowohl einen Fuß 19 auf, der mittels Schrauben 20 an einer Bodenschiene 18 befestigt ist, als auch einen Seitenflansch 21, der mittels Schrauben 22 an der Stuhlung 23 der Zettelwalzenvorrichtung befestigt ist.The facing end faces 12, 13 of the partial rollers 1, 2 are arranged at a distance a (FIG. 2) from one another. In the intermediate space 14 given by this distance α , bearings 15, 16 are arranged which are carried by a disk-like stand 17 which protrudes from the intermediate space 14. The stand 17 has both a foot 19 which is fastened to a bottom rail 18 by means of screws 20 and a side flange 21 which is fastened to the frame 23 of the slip roller device by means of screws 22.

Der Ständer 17 ist zweiteilig und weist innerhalb des Zwischenraumes 14 zur Aufnahme der Lager 15, 16 eine zweiteilige Fassung 25, 25' auf, deren Teile mittels Schrauben 29 verbindbar sind. In den Lagern 15, 16 sind die Zapfen 26, 27 der Teilwalzen 1 bzw. 2 gelagert. Diese Zapfen sitzen fest in auswechselbaren Fassungen 28, die je mit der zugehörigen Teilwalze 1 oder 2 durch Schrauben verbunden sind.The stand 17 is in two parts and has within the space 14 for receiving the bearings 15, 16 has a two-part holder 25, 25 ′, the parts of which can be connected by means of screws 29. In the camps 15, 16, the pins 26, 27 of the partial rollers 1 and 2 are mounted. These pegs sit firmly in interchangeable Sockets 28, which are each connected to the associated roller part 1 or 2 by screws are.

Jede Teilwalze 1, 2 trägt Zettelscheiben 30, die einen dem Außendurchmesser der Teilwalze 1, 2 entsprechenden lichten Innendurchmesser, in tangentialer Richtung gesehen ein U-förmiges Profil, aufweisen und vorzugsweise aus Stahl bestehen. Auf diese Zettelscheiben 30 sind die Kettdrähte 31 aufgewickelt. Die Teilwalze 1, 2 weist an ihrer Oberfläche eine Längsnut 32 auf, in die beim Aufschieben einer Zettelscheibe 30 eine U-Eisen-förmige Leiste 33 eintritt, die längs einer inneren Mantellinie der Zettelscheibe 30 angeordnet ist (Fig. 4). Da die Teilwalze 1, 2 längs ihrer Nut 32 eine Verstärkung 34 aufweist, trägt sie auf der diametral gegenüberliegenden Seite ein Ausgleichsgewicht 35.Each part roll 1, 2 carries slip disks 30 which have an outer diameter corresponding to the part roll 1, 2 clear inside diameter, seen in the tangential direction have a U-shaped profile and preferably made of steel. The warp wires 31 are wound onto these slip disks 30. The partial roller 1, 2 has a longitudinal groove 32 on its surface, into which when it is pushed a note disk 30 a U-iron-shaped bar 33 enters, which is along an inner surface line the slip disk 30 is arranged (Fig. 4). Since the partial roller 1, 2 along its groove 32 a reinforcement 34, it carries a balance weight 35 on the diametrically opposite side.

Die Zettelscheiben 30 sind auf der Teilwalze 1, 2 in axialer Richtung verschiebbar, und die Länge jeder Teilwalze 1, 2 ist so bemessen, daß die erforderliche Anzahl von Zettelscheiben aufgenommen werden kann, auch wenn die zuletzt aufgeschobenen Zettelscheiben mit den Stirnseiten 12 bzw. 13 der Teilwalzen abschneiden. Nach dem Einschwenken der Teilwalzen in die gemeinsame Arbeitsstellung werden die Zettelscheiben 30, wie F i g. 2 zeigt, so verschoben, daß sie nahe an dem Ständer 17 sitzen und den Zwischenraum 14 im wesentlichen überdecken. Für diese Verschiebung der Zettelscheiben steht ein Spielraum b zwischen den Schneckenrädern 5 und der Zettelscheibengruppe der betreffenden Teilwalze zur Verfügung, wie in Fig. 1 links angedeutet ist.The slip disks 30 can be moved in the axial direction on the partial roller 1, 2, and the length of each partial roll 1, 2 is dimensioned so that the required number of slip disks can be accommodated, even if the slip disks that were pushed on last have the end faces 12 and 13 cut off the partial rollers. After the partial rollers have been pivoted into the common working position, the slip disks 30, as shown in FIG. 2 shows, shifted so that they sit close to the stand 17 and cover the gap 14 substantially. For this displacement of the slip disks there is a clearance b between the worm wheels 5 and the slip disk group of the relevant partial roller, as indicated on the left in FIG. 1.

Das Ausfahren der Teilwalzen 1, 2 in waagerechter Richtung kann mittels eines Hilfslagers erfolgen, das auf einer transportablen Ausfahrschiene 36 verschiebbar ist.The extension of the partial rollers 1, 2 in the horizontal direction can be done by means of an auxiliary bearing, which is slidable on a transportable extension rail 36.
