Description

Die Erfindung betrifft eine Längsschneidmaschine für eine Warenbahn, insbesondere Wellpappenbahn, mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a slitting machine for a web, in particular corrugated board web, with the features of the preamble of patent claim 1.

Es ist eine Längsschneidmaschine bekannt, deren dünnes Messer gegen eine mit einer Führungsnut versehene Gegenrolle schneidet über die die Warenbahn daran anliegend läuft. Nachteilig ist, daß diese Gegenrolle getrennt vom Schneidmesser gelagert und quer zur Laufrichtung der Warenbahn einstellbar angeordnet ist. Der Aufwand an Lagerungs- und Einstellmittel ist unnötig groß.A slitting machine is known, the thin knife of which cuts against a counter-roller provided with a guide groove, over which the web runs against it. It is disadvantageous that this counter roller is mounted separately from the cutting knife and is arranged to be adjustable transversely to the running direction of the web. The expenditure on storage and adjustment means is unnecessarily large.

Der Erfindung liegt die Aufgabe zugrunde, eine Längsschneidmaschine so zu verbessern, daß der Lagerungs- und Einstellaufwand für die Schneidvorrichtung vermindert, zudem ein raumgedrängter Aufbau möglich ist.The invention has for its object to improve a slitting machine so that the storage and adjustment effort for the cutting device is reduced, a space-constrained construction is also possible.

Die Erfindung löst diese Aufgabe mit den kennzeichnenden Merkmalen des Patentanspruchs 1.The invention solves this problem with the characterizing features of patent claim 1.

Die Erfindung bietet den Vorteil, daß durch die direkte Verbindung der Gegenfläche für das Schneidmesser mit dem Halteträger desselben zusätzliche Lagerungsmittel und Einstellmittel entfallen.The invention offers the advantage that additional storage means and adjusting means are eliminated by the direct connection of the counter surface for the cutting knife with the holding support of the same.

Vorzugsweise wird die Gegenfläche für das Schneidwerkzeug nach einer Ausgestaltung der Erfindung von einem Tisch mit Führungsspalt für das Schneidmesser gebildet.According to one embodiment of the invention, the counter surface for the cutting tool is preferably formed by a table with a guide gap for the cutting knife.

Nach einer anderen Ausgestaltung der Erfindung wird die gegenüber der Laufgeschwindigkeit der Warenbahn voreilende hohe Drehgeschwindigkeit des Schneidmessers durch Einschaltung eines Übersetzungstriebs zwischen Antriebswelle und Schneidmesser beträchtlich erhöht. Dabei liegt die Drehzahl der Antriebsgeschwindigkeit unterhalb deren kritischen Eigendrehzahl.According to another embodiment of the invention, the leading speed is higher than the running speed of the material web Rotation speed of the cutting knife increased considerably by switching on a transmission drive between the drive shaft and the cutting knife. The speed of the drive speed is below its critical intrinsic speed.

Nach einer anderen Ausgestaltung der Erfindung ist, wie üblich, die Schneidvorrichtung mit Messerantriebswelle, Einstellspindeln und Führungsträger schwenkbar in den Seitenständern der Maschine gelagert. Dadurch kann die Schneidvorrichtung in und außer Arbeitsstellung gebracht werden.According to another embodiment of the invention, as usual, the cutting device with knife drive shaft, adjusting spindles and guide carrier is pivotally mounted in the side stands of the machine. This allows the cutting device to be brought into and out of the working position.

Nach einer weiteren Ausgestaltung der Erfindung kann einer solchen Schneidvorrichtung eine weitere, z. B. dahinter oder darüber, zugeordnet werden. Es ist dann ein üblicher Tandembetrieb möglich. Hierdurch ist es möglich, die außer Betrieb befindlichen Schneidmesser für neue Einstellungen vorzubereiten und in kürzester Zeit bei Bedarf in Arbeitsstellung zu überführen. Auch ist ein Ersatz der Schneidmesser bei gleicher Einstellage möglich, wodurch die Gesamtstandzeit der Schneidmesser erhöht wird.According to a further embodiment of the invention, such a cutting device, a further, for. B. behind or above. Normal tandem operation is then possible. This makes it possible to prepare the cutting knives that are not in use for new settings and to move them to the working position as quickly as possible. It is also possible to replace the cutting knives with the same setting, which increases the overall service life of the cutting knives.

Nach einer weiteren Ausgestaltung der Erfindung ist es auch möglich, die Längsschneidvorrichtung mit einer Rillvorrichtung zu einer Längsschneid- und/oder Rillmaschine zu kombinieren.According to a further embodiment of the invention, it is also possible to combine the longitudinal cutting device with a creasing device to form a longitudinal cutting and / or creasing machine.

Die Längsschneidmaschine 1, insbesondere für eine Wellpappenbahn 2, weist nach Fig. 1 Seitenständer 3 auf, in denen ein Führungsträger 4 wie üblich schwenkbar gelagert ist. Der Führungsträger 4 wird von zwei parallelen Holmen 5 gebildet, die an ihren Enden in nicht dargestellter Weise starr mit Seitenschildern verbunden sind. Die Seitenschilder sind um nicht dargestellte Schwenkzapfen schwenkbar gelagert. Eine ebenfalls nicht dargestellte Schwenkvorrichtung kann den Führungsträger 4 in Arbeitsstellung bzw. aus der Arbeitsstellung bringen.The longitudinal cutting machine 1, in particular for a corrugated cardboard web 2, has, according to FIG. 1, side stands 3, in which a guide carrier 4 is pivotably mounted as usual. The guide carrier 4 is formed by two parallel bars 5, which are rigidly connected at their ends in a manner not shown with side plates. The side plates are pivotally mounted about pivot pins, not shown. A swiveling device, also not shown, can bring the guide carrier 4 into the working position or out of the working position.

Die Holme 5 sind mit Gleitstangen 6 versehen. An diesen sind verschiebbar Halteträger 7 mittels Gleitlager 6' gelagert. In Querrichtung zur Wellpappenbahn 2 sind mehrere Halteträger 7 vorgesehen, die über nur schematisch angedeutete Einstellspindeln, Kupplungen in vorbestimmte Stellungen ein- und feststellbar sind.The bars 5 are provided with slide rods 6. These are slidably supported by means of slide bearings 6 '. In the transverse direction to the corrugated cardboard web 2, a plurality of support brackets 7 are provided, which can be set and locked in predetermined positions by means of adjusting spindles and couplings which are only indicated schematically.

Jeder Halteträger 7 wird von einer Antriebswelle 8 durchquert. Auf dieser sitzt, schiebbar und mit dem Halteträger 7 verbunden, ein Übersetzungsrad 9.Each support bracket 7 is traversed by a drive shaft 8. A transmission wheel 9 sits on this, slidably and connected to the holding bracket 7.

Auf dem Halteträger 7 ist parallel versetzt zum Übersetzungsrad 9 ein Schneidmesser 10 drehbar gelagert. Das Schneidmesser 10 trägt ein Übersetzungsrad 11, welches mit dem Übersetzungsrad 9 eine Übersetzung bildet. Vorzugsweise sind die beiden Übersetzungsräder über einen Riementrieb 12, z. B. einen Zahnriemen, miteinander verbunden. Das Schneidmesser 10 wird über dieses Getriebe mit einer gegenüber der Antriebswelle 8 höheren Drehzahl angetrieben. Auf diese Weise ist eine Drehzahl für das Schneidmesser 10 erreichbar, die über der kritischen Drehzahl der Antriebswelle 8 liegt.On the support bracket 7, a cutting knife 10 is rotatably mounted parallel to the translation wheel 9. The cutting knife 10 carries a translation wheel 11 which forms a translation with the translation wheel 9. Preferably, the two translation wheels via a belt drive 12, z. B. a toothed belt connected together. The cutting knife 10 is driven via this gear at a higher speed than the drive shaft 8. In this way, a speed for that Cutting knife 10 accessible, which is above the critical speed of the drive shaft 8.

Das vorzugsweise sehr dünn und schlank ausgeführte Schneidmesser 10 wirkt mit einer Gegenfläche 15 zusammen, über die die Wallpappenbahn 2 daran anliegend läuft. Diese Gegenfläche 15 ist vorzugsweise ein Tisch 16. Dieser Tisch 16 besitzt einen Führungsspalt 17, in den der Randbereich des Messers 10 eindringt. Der Führungsspalt 17 setzt sich nach abwärts in eine konische Ausnehmung 18 fort. Die vorderen und hinteren Enden des Tisches 16 sind massiv ausgebildet. Die der Wellpappenbahn 2 zugekehrte Tischseite kann mit ein Gleitschicht versehen sein.The cutting knife 10, which is preferably very thin and slim, cooperates with a counter surface 15 over which the cardboard web 2 runs against it. This counter surface 15 is preferably a table 16. This table 16 has a guide gap 17 into which the edge area of the knife 10 penetrates. The guide gap 17 continues downwards into a conical recess 18. The front and rear ends of the table 16 are solid. The table side facing the corrugated cardboard web 2 can be provided with a sliding layer.

Das in Bahnlaufrichtung gesehene hintere Ende des Tisches 16 ist mittels Schrauben 19 mit einem Verbindungsteil 20 fest verbunden, dessen Stärke etwa der Stärke des Schneidmessers 10 entspricht oder dünner ist.The rear end of the table 16 seen in the direction of web travel is firmly connected by means of screws 19 to a connecting part 20, the thickness of which corresponds approximately to the thickness of the cutting knife 10 or is thinner.

Das Verbindungsteil 20 ist mit dem Halteträger 7 mittels Schrauben 14 fest verbunden.The connecting part 20 is firmly connected to the support bracket 7 by means of screws 14.

Mit dem Halteträger 7 ist überhalb des Tisches 16 mit Abstand dazu beiderseits des Schneidmessers 10 ein Führungsteil 21 fest verbunden. Dieses schuhartige Führungsteil 21 erleichtert mit seinem Ende 22 die Zuführung der Wellpappenbahn 2 zum Schneidmesser 10. Das eine Ende ist mit einem Langloch 23 mit Halteschraube versehen, so daß das Führungsteil 21 in Richtung des Langloches 23 einstellbar ist.A guide part 21 is fixedly connected to the holding support 7 above the table 16 at a distance therefrom on both sides of the cutting knife 10. This shoe-like guide part 21, with its end 22, facilitates the feeding of the corrugated cardboard web 2 to the cutting knife 10. One end is provided with an elongated hole 23 with a retaining screw, so that the guide part 21 can be adjusted in the direction of the elongated hole 23.

Wie aus Fig. 2 ersichtlich, ist das Schneidmesser 10 auf einem Flansch 25 gelagert und mittels eines Deckels 26 über eine Schraube 27 geklemmt. Der Flansch 25 geht in einen zylindrischen Stummel 28 über, der mittels Kugellager 29 in Seitenteilen 30 des Halteträgers 7 drehbar gelagert ist. Die Seitenteile 30 sind durch eine Deckplatte 30' miteinander verbunden. Auf dem Stummel 28 sitzt zwischen den Kugellagern 29 das Übersetzungsrad 11, über welches der Riementrieb 12 verläuft.2, the cutting knife 10 is mounted on a flange 25 and clamped by means of a cover 26 via a screw 27. The flange 25 merges into a cylindrical stub 28 which is rotatably mounted in side parts 30 of the holding support 7 by means of ball bearings 29. The side parts 30 are connected to one another by a cover plate 30 '. On the stub 28 sits between the ball bearings 29, the transmission wheel 11, over which the belt drive 12 runs.

Der Stummel 28 ist axial durch eine Scheibe 31 gesichert, die mittels der Schraube 32 befestigt ist und deren Rand gegen das eine Kugellager 29 anliegt.The stub 28 is axially secured by a washer 31 which is fastened by means of the screw 32 and the edge of which rests against the one ball bearing 29.

Wie aus Fig. 3 ersichtlich, nimmt der Halteträger 7, der schiebbar über Gleitlager 6' und Gleitstangen 6 gelagert ist, das Übersetzungsrad 9 über Kugellager 33 auf. Diese stützen sich auf dem Übersetzungsrad 9 ab. Das Übersetzungsrad 9 besitzt einen Fuß 34, der schiebbar, aber nicht verdrehbar auf der Antriebswelle 8 sitzt.3, the support bracket 7, which is slidably supported by slide bearings 6 'and slide rods 6, receives the transmission gear 9 via ball bearings 33. These are based on the translation wheel 9. The translation gear 9 has a foot 34 which is slidable but not rotatable on the drive shaft 8.
