Abstract
Description
Die Erfindung betrifft eine Vorrichtung bzw. ein Verfahren zum Querperforieren von mehreren Bahnen gemäß dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 6. Eine Vorrichtung bzw. ein Verfahren mit solchen Merkmalen ist aus US 5 882 287 A bekannt.The invention relates to a device or a method for transverse perforation of several webs according to the preamble of
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.To produce bags of sheet material, it is necessary to form a tube from the sheet material. Frequently, this hose is provided after its formation with transverse perforations in order to be able to separate the endless hose into pieces of hose. At the isolated pieces of tubing are often formed in other machines, for example, in so-called bottom layers, one or both ends bag bottoms.
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 various applications, however, bags are necessary whose walls consist of different layers. Thus, for example, an inner, moisture-impermeable layer, which often consists of a thin plastic film, be surrounded by a layer of paper which absorbs the forces caused by the transported goods. In order for each of these materials to be welded or glued to itself in the bottom layer, however, the perforations serving 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 staggered perforations are referred to as staggered cut perforations and can only be introduced into the individual webs prior to tube formation.
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 fassen 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 Maschinengestell, in welchem die Achsen, um welche die Messer rotieren, gelagert sind, bewegbar ist.Devices for attaching staggered perforations are known. These include a sawtooth knife for each web to be perforated, which rotates about 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 dip. In order to produce pieces of hose of different lengths, the distance of the knife to the axis about which they rotate, changeable. Consequently, the distances of the counter-pressure rollers to the axes about which the blades rotate, must be displaced. This counterpressure roller provides the back pressure for the perforation process. As a rule, they grasp that the knives pierce the webs during perforation, without the knives being damaged. For this purpose, mainly grooving or brushing rollers are used. In order to always obtain an equal distance between two transverse perforations in all tracks, the counter-pressure rollers are usually movable together. For this purpose, all counter-pressure rollers are mounted on a support which is movable relative to the machine frame in which the axes about which the blades 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 are rotatably mounted on the support one ends of the links. The other ends of the links are rotatably mounted in the machine frame, so that a parallelogram is created for the wearer. For the purpose of moving the carrier is attached to this another lever 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 to be considered that such a device requires a large number of bearings and thus is mechanically complex.
Aufgabe der Erfindung ist es daher, eine Vorrichtung sowie ein Verfahren vorzuschlagen, die mechanisch einfacher gehalten sind.The object of the invention is therefore to propose an apparatus and a method which are mechanically simpler.
Die Aufgabe wird gelöst durch den Merkmalen des Anspruchs 1 bzw. des Anspruchs 6.The object is solved by the features of
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.Thus, the carrier is displaceable substantially along a line connecting the axes of the backup rolls and the axes about which the associated knives rotate.
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.In a particularly preferred embodiment of the invention linear guide means are arranged between the carrier and the machine frame, the guide direction is substantially parallel to the line connecting the axes of the counter-pressure roller and the axes of rotation about which the blades rotate. In this way it is possible to move the counter-pressure rollers in the radial direction to the axes of rotation of the knife.
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 guide rails fixed to the support, which are displaceably mounted in guides fastened to the machine frame. Such guide means allow the displacement of the carrier without a great effort. When using several rails and guides also tilting of the carrier is excluded, so that all counter-pressure rollers maintain a precisely uniform distance from the axis of rotation of the knife.
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 is movable relative to the machine frame. Here, various drives are conceivable, such as a linear motor or a manually operated traction means.
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 via the spindle is converted into a linear movement of the spindle nut.
Ein Ausführungsbeispiel der Erfindung geht aus der gegenständlichen Beschreibung und aus den Zeichnungen hervor.An embodiment of the invention will become apparent from the subject description and from the drawings.
