Description
Es gibt verschiedene Systeme für Kreuzleger (Fig. 1), das sind Maschinen, die eine dünne Warenbahn (1), zum Bei spiel einen Krempelflor, auf ein rechtwinklig zur Zuführungs richtung (2) angeordnetes Abzugsband (3) abtäfeln. Die Dicke des abgetäfelten Materials kann dadurch variiert werden, daß bei gleichbleibender Zuführgeschwindigkeit die Geschwindigkeit des unter rechtem Winkel zur Zuführungsrichtung (2) verlaufen den Abzugsbandes (3) verändert wird.There are various systems for stacker ( Fig. 1), these are machines that panel a thin web ( 1 ), for example a cardboard pile, on a take-off belt ( 3 ) arranged at right angles to the feed direction ( 2 ). The thickness of the paneled material can be varied by changing the speed of the take-off belt ( 3 ) while the feed speed remains the same at right angles to the feed direction ( 2 ).
Diese verschiedenen Kreuzlegersysteme haben gemeinsam, daß die Übergabe der Warenbahn auf das Abzugsband mit Ablieferungs walzen (4) erfolgt, die aus Baugründen horizontal und unter 90 Grad zur Zuführrichtung angeordnet sind. Aus Fig. 2a und 2b ist ersichtlich, daß nur bei unendlicher Lagenzahl (5) (und/oder bei unendlicher Legebreite) der Winkel zwischen Abzugsrichtung und Zuführrichtung 90 Grad beträgt. Bei end licher Lagenzahl (5) und kleiner werdender Legebreite wächst diser Winkel über 90 Grad an, es entsteht ein Winkelfehler (6). Fig. 2a zeigt als Beispiel acht Einzellagen, Fig. 2b zum Bei spiel zwei Einzellagen.These different stacker systems have in common that the transfer of the web onto the take-off belt with delivery rollers ( 4 ), which are arranged horizontally and at 90 degrees to the feed direction for building reasons. From FIGS. 2a and 2b it can be seen that only with an infinite number of layers ( 5 ) (and / or with an infinite laying width) is the angle between the draw-off direction and the feed direction 90 degrees. With a finite number of layers ( 5 ) and a smaller laying width, this angle increases over 90 degrees, an angle error occurs ( 6 ). Fig. 2a shows eight individual layers as an example, Fig. 2b for example two individual layers.
Da die Ablieferungswalzen (4) des Kreuzlegers in der Praxis unter 90 Grad zur Zuführrichtung (2) angeordnet sind, kann man endliche Lagenzahlen (5) bei einem üblichen VerhältnisSince the delivery rollers ( 4 ) of the stacker are in practice arranged at 90 degrees to the feed direction ( 2 ), finite number of layers ( 5 ) can be obtained at a normal ratio
in der Praxis nur dann legen, wenn die Warenbahn (1) eine Elastizität aufweist. So sind zum Beispiel bei einer Krem pelflorbreite (7) von 2500 mm und einer Legebreite (8) von 2500 mm gerade noch 6 Einzellagen möglich, ohne daß durch den Winkelfehler (6) auf dem Abzugsband (3) Falten entstehen.in practice, lay only when the web ( 1 ) has elasticity. For example, with a Krem pelflorbreide ( 7 ) of 2500 mm and a laying width ( 8 ) of 2500 mm just 6 individual layers are possible without the wrinkle ( 6 ) on the trigger belt ( 3 ) wrinkles.
Aufgabe der vorliegenden Erfindung ist es, diesen Winkel fehler (6) zu kompensieren und damit sogar zwei Einzellagen ohne Falten zu ermöglichen, was bisher wegen der maschinen bedingten Anordnung unter 90 Grad nicht möglich war. Die Erfindung löst diese Aufgabe mit den Merkmalen im Haupt anspruch (Fig. 3).The object of the present invention is to compensate for this angle error ( 6 ) and thus even allow two individual layers without folds, which was not possible hitherto because of the machine-related arrangement at 90 degrees. The invention solves this problem with the features in the main claim ( Fig. 3).
Alle bisher bekannten Kreuzlegerkonstruktionen arbeiten mit Transportbändern, die horizontal eingebaute Ablieferungswal zen haben, und die unter 90 Grad zur Zuführrichtung stehen. Die Erfindung besteht aus einer Fördereinrichtung (9), deren Umlenkungen unter einem Winkel (10) zueinander angeordnet sind, der genau dem Winkelfehler (6) entspricht, der sich aus dem Verhältnis Zuführbreite (7) zu Legebreite (8) und der Lagenzahl (5) ergibt. All previously known stacker designs work with conveyor belts that have horizontally installed delivery rollers and that are at 90 degrees to the feed direction. The invention consists of a conveyor device ( 9 ), the deflections of which are arranged at an angle ( 10 ) to one another which corresponds exactly to the angular error ( 6 ), which results from the ratio of the feed width ( 7 ) to the laying width ( 8 ) and the number of layers ( 5 ) results.
Damit wird ein dreieckförmiges Stück der Warenbahn in eine senkrechte Ebene verlagert, wobei der spitze Winkel (10) des Dreiecks (9) dem beschriebenen Winkelfehler (6) ent spricht.So that a triangular piece of the web is moved into a vertical plane, the acute angle ( 10 ) of the triangle ( 9 ) speaks the described angular error ( 6 ) ent.
Die Erfindung kann den Winkelfehler (6) vollkommen korri gieren, d. h., daß auch unelastische Warenbahnen wie Papier etc. mit der Erfindung faltenfrei gelegt werden können. Bei Änderung der Legebreite (8) oder der Lagenzahl (5) än dert sich der Winkelfehler (6). Die Vorrichtung kann so aus geführt sein, daß mit Hilfe einer dritten Umlenkung oder Ähnlichem innerhalb der Fördereinrichtung (9) der Winkel verändert und angepaßt werden kann.The invention can completely correct the angular error ( 6 ), ie that inelastic webs such as paper etc. can also be laid wrinkle-free with the invention. When changing the laying width ( 8 ) or the number of layers ( 5 ), the angle error ( 6 ) changes. The device can be performed in such a way that the angle can be changed and adapted with the aid of a third deflection or the like within the conveyor device ( 9 ).
Angetrieben wird die Fördereinrichtung durch Kopplung mit den Ablieferungswalzen (4) des Kreuzlegers, ein eigener An trieb ist nicht erforderlich.The conveyor is driven by coupling with the delivery rollers ( 4 ) of the cross-layer, a separate drive is not required.
Die Erfindung ist in den beiliegenden Zeichnungen beispiels weise und schematisch dargestellt.The invention is exemplary in the accompanying drawings shown wisely and schematically.

Das Abzugsband muß unter dem Kom pensationswinkel (11) schräg nach unten führen. Fig. 3 is a schematic representation of the invention where the angular error ( 6 ) is compensated for the 4 individual layers by the vertically arranged, triangular-shaped conveying device ( 9 ) and the angle between the supply and take-off belt can again be 90 degrees. The trigger belt must run obliquely downwards under the compensation angle ( 11 ).
