Description

Vorrichtung zur Perforation einzelner Bahnen in einer Schlauchmaschine zur Herstellung von mehrlagigen Schläuchen Device for perforating individual webs in a tube machine for the production of multi-layer tubes
Die Erfindung betrifft eine Vorrichtung zum Querperforieren von mehreren Bahnen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for cross-perforating a plurality of webs according to the preamble of claim 1.
Zur Herstellung von Säcken aus bahnförmigen Material ist es notwendig, aus dem bahnförmigen Material einen Schlauch zu bilden. Häufig wird dieser Schlauch nach seiner Bildung mit Querperforationen versehen, um den Endlosschlauch zu Schlauchstücken vereinzeln zu können. An die vereinzelten Schlauchstücke werden häufig in weiteren Maschinen, beispielsweise in so genannten Bodenlegern, einendig oder beidendig Sackböden angeformt.For the production of sacks from sheet material, it is necessary to form a tube from the sheet material. This tube is often provided with transverse perforations after it has been formed, in order to be able to separate the endless tube into tube pieces. Sack bottoms are often molded onto the individual pieces of hose in other machines, for example in so-called floor layers, at one or both ends.
Für verschiedene Anwendungen sind jedoch Säcke notwendig, deren Wände aus verschiedenen Schichten bestehen. So kann beispielsweise eine innere, feuchtigkeitsundurchlässige Schicht, welche häufig aus einer dünnen Kunststofffolie besteht, von einer Papierschicht, welche die von dem Transportgut verursachten Kräfte auffängt, umgeben sein. Damit im Bodenleger jedoch jedes dieser Materialien mit sich selbst verschweißt oder verklebt werden kann, müssen die der Vereinzelung der Schlauchabschnitte dienenden Perforationen so in jede einzelne Materialbahnen eingebracht werden, dass diese nicht deckungsgleich mit den Perforationen der jeweils anderen Materialbahnen sind. Solche versetzten Perforationen werden als Staffelschnittperforationen bezeichnet und können nur vor der Schlauchbildung in die einzelnen Materialbahnen eingebracht werden.For different applications, however, sacks are necessary, the walls of which consist of different layers. For example, an inner, moisture-impermeable layer, which often consists of a thin plastic film, can be surrounded by a paper layer, which absorbs the forces caused by the goods to be transported. So that each of these materials can be welded or glued to itself in the floor layer, the perforations used to separate the tube sections must be introduced into each individual material web so that they are not congruent with the perforations of the other material webs. Such offset perforations are referred to as staggered perforations and can only be introduced into the individual material webs before the tube is formed.
Vorrichtungen zum Anbringen von Staffelperforationen sind bekannt. Diese umfassen für jede zu perforierende Bahn ein sägezahnförmiges Messer, welches um eine Achse rotiert, und eine Gegendruckwalze, auf welcher die zu perforierende Bahn läuft und in deren Nuten die Zähne des Messers eintauchen können. Um Schlauchstücke verschiedener Längen produzieren zu können, ist der Abstand der Messer zu der Achse, um welche sie rotieren, veränderbar. Demzufolge müssen auch die Abstände der Gegendruckwalzen zu den Achsen, um welche die Messer rotieren, verschiebbar sein. Diese Gegendruckwalze stellen den Gegendruck für den Perforationsprozess bereit. In der Regel lassen sie zu, dass die Messer die Bahnen beim Perforieren durchstechen, ohne dass die Messer geschädigt werden. Zu diesem Zweck werden vorwiegend Nut- oder Bürstwalzen benutzt. Um bei allen Bahnen immer einen gleichen Abstand zwischen zwei Querperforationen zu erhalten, sind gewöhnlich die Gegendruckwalzen gemeinsam bewegbar. Zu diesem Zweck sind alle Gegendruckwalzen auf einem Träger gelagert, der relativ zum Maschiπengestell, in welchem die Achsen, um welche die Messer rotieren, gelagert sind, bewegbar ist.Devices for applying staggered perforations are known. For each web to be perforated, these comprise a sawtooth-shaped knife, which rotates around an axis, and a counter-pressure roller on which the web to be perforated runs and in whose grooves the teeth of the knife can be immersed. In order to be able to produce hose pieces of different lengths, the distance between the knives and the axis around which they rotate can be changed. As a result, the distances between the counter-pressure rollers and the axes around which the knives rotate must also be displaceable. This counter pressure roller provides the counter pressure for the perforation process. As a rule, they allow the knives to pierce the webs during perforation without the knives being damaged. Grooved or brushed rollers are mainly used for this purpose. In order to always maintain the same distance between two transverse perforations on all webs, the counter-pressure rollers can usually be moved together. For this purpose, all counter-pressure rollers are mounted on a carrier which is movable relative to the machine frame in which the axes about which the knives rotate are mounted.
In den bekannten Vorrichtungen dieser Art sind an dem Träger drehbar die einen Enden von Lenkern gelagert. Die anderen Enden der Lenker sind drehbar im Maschinengestell gelagert, so dass für den Träger eine Parallelogrammführung entsteht. Zum Zwecke des Verschiebens des Trägers ist an diesem ein weiterer Hebel angebracht, auf den ein Antrieb wirkt. Dieser Antrieb ist drehbar im Maschinengestell gelagert.In the known devices of this type, one end of the handlebars is rotatably mounted on the carrier. The other ends of the handlebars are rotatably mounted in the machine frame, so that a parallelogram guide is created for the wearer. For the purpose of moving the carrier, another lever is attached to it, on which a drive acts. This drive is rotatably mounted in the machine frame.
Als nachteilig ist jedoch anzusehen, dass eine solche Vorrichtung eine große Anzahl von Lagern benötigt und somit mechanisch aufwändig ist.A disadvantage, however, is that such a device requires a large number of bearings and is therefore mechanically complex.
Aufgabe der Erfindung ist es daher, eine Vorrichtung vorzuschlagen, die mechanisch einfacher gehalten ist.The object of the invention is therefore to propose a device which is kept mechanically simpler.
Die Aufgabe wird gelöst durch das kennzeichnende Merkmal des Anspruchs 1.The object is achieved by the characterizing feature of claim 1.
Demnach ist der Träger im wesentlichen entlang einer Linie verschiebbar, welche die Achsen der Gegendruckwalzen und die Achsen, um welche die zugehörigen Messer rotieren, verbindet. In einer besonders bevorzugten Ausgestaltung der Erfindung sind zwischen dem Träger und dem Maschinengestell lineare Führungsmittel angeordnet, deren Führungsrichtung im wesentlichen parallel zu der Linie verläuft, welche die Achsen der Gegendruckwalze und die Drehachsen, um welche die Messer rotieren, verbindet. Auf diese Weise ist es möglich, die Gegendruckwalzen in radialer Richtung auf die Drehachsen der Messer zu zu bewegen.Accordingly, the carrier is essentially displaceable along a line which connects the axes of the counter-pressure rollers and the axes about which the associated knives rotate. In a particularly preferred embodiment of the invention, linear guide means are arranged between the carrier and the machine frame, the guide direction of which runs essentially parallel to the line connecting the axes of the counter-pressure roller and the axes of rotation about which the knives rotate. In this way it is possible to move the counter-pressure rollers in the radial direction towards the axes of rotation of the knives.
Besonders vorteilhaft ist es dabei, wenn die Führungsmittel am Träger befestigte Laufschienen umfassen, welche in am Maschinengestell befestigten Führungen verschieblich gelagert sind. Derartige Führungsmittel gestatten die Verschiebung des Trägers ohne einen großen Kraftaufwand. Bei Einsatz von mehreren Laufschienen und Führungen ist zudem eine Verkantung des Trägers ausgeschlossen, so dass alle Gegendruckwalzen einen exakt einheitlichen Abstand zur Drehachse der Messer einhalten.It is particularly advantageous if the guide means comprise running rails which are fastened to the carrier and are slidably mounted in guides fastened to the machine frame. Such guide means allow the carrier to be moved without great effort. When using several running rails and guides, tilting of the carrier is also excluded, so that all counter-pressure rollers maintain a precisely uniform distance from the axis of rotation of the knives.
In weiterer Ausgestaltung der Erfindung ist ein Linearantrieb vorgesehen, mit welchem der Träger relativ zum Maschinengestell verfahrbar ist. Hierbei sind verschiedene Antriebe denkbar, etwa ein Linearmotor oder ein manuell bedientes Zugmittel.In a further embodiment of the invention, a linear drive is provided with which the carrier can be moved relative to the machine frame. Various drives are conceivable here, such as a linear motor or a manually operated traction mechanism.
In einer bevorzugten Ausführungsform umfasst der Linearantrieb jedoch eine von einem Motor angetriebene Spindel-Spindelmutter-Kombination, durch welche die Rotationsbewegung der Motorachse über die Spindel in eine Linearbewegung der Spindelmutter umgesetzt wird.In a preferred embodiment, however, the linear drive comprises a spindle-spindle nut combination driven by a motor, by means of which the rotational movement of the motor axis is converted into a linear movement of the spindle nut via the spindle.
Ein Ausführungsbeispiel der Erfindung geht aus der gegenständlichen Beschreibung und aus den Zeichnungen hervor.An embodiment of the invention can be seen from the description of the matter and from the drawings.

Die Figuren 1 und 2 zeigen eine Vorrichtung, mit der in die einzelnen Materialbahnen 11 Perforationen eingebracht werden können. Im Maschinengestell 1 sind mehrere Drehachsen 2 gelagert, welche die Messerträger 3 tragen. An den äußeren Enden der Messerträger 3 sind die Messer 4 befestigt. Der Abstand der Außenkanten der Messer 4 können mithilfe eines nicht näher beschriebenen Mechanismus eingestellt werden. Wird die aus den Drehachsen 2, den Messerträgern 3 und den Messern 4 bestehende Einheit in Rotation versetzt, so überstreichen die Außenkanten der Messer 4 den Hüllkreis 5.FIGS. 1 and 2 show a device with which perforations can be made in the individual material webs 11. A plurality of axes of rotation 2 are supported in the machine frame 1 and carry the knife carriers 3. The knives 4 are fastened to the outer ends of the knife carriers 3. The distance between the outer edges of the knives 4 can be adjusted using a mechanism that is not described in detail. If the unit consisting of the axes of rotation 2, the knife carriers 3 and the knives 4 is set in rotation, the outer edges of the knives 4 sweep over the enveloping circle 5.
Der Abstand der Gegendruckwalzen 7, auf welchen die Materialbahnen 11 geführt werden, müssen auf den Durchmesser des Hüllkreises 5 eingestellt werden. Um dieses zu ermöglichen, sind die Gegendruckwalzen 7 in einem Träger 6 drehbar gelagert. An diesem Träger 6 sind drehbar die einen Enden mehrerer Lenker 10 befestigt. Die anderen Enden der Lenker 10 sind drehbar im Maschinengestell 1 gelagert. Für den Träger 6 und damit für die Gegendruckwalzen 7 ergibt sich eine parallelogrammartige Führung. Zur weiteren Führung der Materialbahnen 11 dienen die Umlenkwalzen 9, die drehbar in Haltern 8, welche mit dem Träger 6 verbunden sind, gelagert sind.The distance between the counter-pressure rollers 7 on which the material webs 11 are guided must be set to the diameter of the enveloping circle 5. In order to make this possible, the counter-pressure rollers 7 are rotatably mounted in a carrier 6. The one ends of a plurality of links 10 are rotatably attached to this carrier 6. The other ends of the links 10 are rotatably mounted in the machine frame 1. A parallelogram-like guidance results for the carrier 6 and thus for the counter-pressure rollers 7. The deflecting rollers 9, which are rotatably mounted in holders 8, which are connected to the carrier 6, serve to further guide the material webs 11.
Die Einstellung des Abstandes der Gegendruckwalzen 7 zu den Drehachsen 2 der Messer 4 erfolgt durch die Antriebseinheit 12, der drehbar mit dem Maschinengestell 1 verbunden ist. Die Antriebseinheit 12 umfasst einen Motor 13, der eine nicht dargestellte Spindelmutter in Drehung versetzt. Dadurch wird die Spindel 14 relativ zur Antriebseinheit 12 verfahren. Mit der Spindel 14 ist fest ein Hebel 15 verbunden, der ebenfalls drehbar im Träger 6 gelagert ist. Die Figur 1 zeigt die beschriebene Vorrichtung für eine große Abschnittlänge der zu produzierenden Schlauchstücke. Dabei ist die Spindel 14 ausgefahren. Die Figur 2 zeigt die gleiche Vorrichtung, jedoch für kleine Schlauchabschnittlängen. Bei diesem Beispiel ist die Spindel 14 eingefahren.The setting of the distance between the counter-pressure rollers 7 and the axes of rotation 2 of the knives 4 is carried out by the drive unit 12, which is rotatably connected to the machine frame 1. The drive unit 12 comprises a motor 13 which rotates a spindle nut (not shown). As a result, the spindle 14 is moved relative to the drive unit 12. A lever 15 is fixedly connected to the spindle 14 and is also rotatably mounted in the carrier 6. FIG. 1 shows the device described for a large section length of the tube pieces to be produced. The spindle 14 is extended. Figure 2 shows the same device, but for small hose section lengths. In this example, the spindle 14 is retracted.
Die Figuren 3 und 4 zeigen die erfindungsgemäße Vorrichtung zum Anbringen von Perforationen in die Materialbahnen 11. Die aus den Drehachsen 2, den Messerhaltern 3 und den Messern 4 bestehenden Einheiten sind wie in der Vorrichtung gemäß dem Stand der Technik im Maschinengestell 1 drehbar gelagert. Die Materialbahn 11 wird über die Gegendruckwalzen 7 und die Umlenkwalzen 9 geführt. Die Gegendruckwalzen 7 und die Umlenkwalzen 9 sind drehbar in einem Träger 17 gelagert. Dieser Träger 17 kann die gezeigte Kontur aufweisen, wobei der Träger die Drehachsen 2 der Messer 4 zangenartig umfasst. Diese Kontur erlaubt es, Bauraum einzusparen und somit die Vorrichtung kompakter zu gestalten.FIGS. 3 and 4 show the device according to the invention for making perforations in the material webs 11. The units consisting of the axes of rotation 2, the knife holders 3 and the knives 4 are rotatably mounted in the machine frame 1 as in the device according to the prior art. The material web 11 is guided over the counter-pressure rollers 7 and the deflection rollers 9. The counter pressure rollers 7 and the deflection rollers 9 are rotatably mounted in a carrier 17. This carrier 17 can have the contour shown, the carrier comprising the axes of rotation 2 of the knives 4 in the manner of pliers. This contour makes it possible to save installation space and thus to make the device more compact.
An dem Träger 17 sind Laufschienen 18 befestigt, die verschieblich in am Maschinengestell 1 befestigten Führungen 19 gelagert sind. Die Laufschienen 18 und die Führungen 19 sind parallel zu den Geraden ausgerichtet, welche durch die Rotationsachsen der Gegendruckwalzen 7 und der Drehachse 2 der Messer festgelegt sind. Die daraus resultierende Bewegungsrichtung des Trägers 17 ist durch den Doppelpfeil A dargestellt.On the carrier 17 rails 18 are attached, which are slidably mounted in guides 19 attached to the machine frame 1. The running rails 18 and the guides 19 are aligned parallel to the straight lines which are defined by the axes of rotation of the counter-pressure rollers 7 and the axis of rotation 2 of the knives. The resulting direction of movement of the carrier 17 is shown by the double arrow A.
Die Einstellung des Abstandes zwischen den Gegendruckwalzen 7 und den Drehachsen 2 der Messer erfolgt über den Motor 13, der am Maschinengestell 1 befestigt ist und der eine Spindel 14 in Rotation versetzt. Diese Spindel 14 wirkt auf eine am Träger 17 befestigte Spindelmutter 16 und kann so den Träger in eine Linearbewegung versetzen.The setting of the distance between the counter-pressure rollers 7 and the axes of rotation 2 of the knives takes place via the motor 13 which is fastened to the machine frame 1 and which sets a spindle 14 in rotation. This spindle 14 acts on a spindle nut 16 fastened to the carrier 17 and can thus set the carrier into a linear movement.
Die Figur 3 zeigt die zur Figur 1 analoge Betriebssituation. Die Figur 4 zeigt die zur Figur 2 analoge Betriebssituation. FIG. 3 shows the operating situation analogous to FIG. 1. FIG. 4 shows the operating situation analogous to FIG. 2.
