Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Querperforieren von mehreren Bahnen gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a transverse perforating apparatus and method of several lanes according to the preamble of claim 1.
Ein solches Verfahren ist durch die WO 02/42060 A1 bekannt geworden. Dabei werden in das Bahnmaterial kleine Löcher oder Durchbrüche eingebracht, welche das Entlüften des späteren Sackes bei oder nach dessen Befüllung ermöglichen.One such method has become known from WO 02/42060 A1. In this case, small holes or openings are introduced into the web material, which the venting later Sackes at or after its filling enable.
Zur
Herstellung von Säcken
aus bahnförmigem
Material ist es notwendig, aus dem bahnförmigen Material einen Schlauch
zu bilden. Häufig
wird dieser Schlauch nach seiner Bildung mit Querperforationen versehen.
Die
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 Materialbahn eingebracht werden, dass diese nicht deckungsgleich mit den Perforationen der jeweils anderen Materialbahnen sind. Solche versetzten Perforationen werden als Staffelschnittpertorationen bezeichnet und können nur vor der Schlauchbildung in die einzelnen Materialbahnen eingebracht werden.For different Applications, however, are bags necessary, their walls consist of different layers. For example, a inner, moisture-impermeable Layer, which is often off a thin one Plastic film consists of a layer of paper which is made of paper forces caused by the cargo fields, be surrounded. So in the bottom layer, however, each of these materials welded to itself or can be glued the separation of the hose sections serving perforations be introduced into each web so that these not congruent with the perforations of the other material webs are. Such staggered perforations are called staggered cuts designated and can introduced only before the tube formation in the individual material webs become.
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 Maschinengestell, in welchem die Achsen, um welche die Messer rotieren, gelagert sind, bewegbar ist.devices for attaching staggered perforations are known. These include for every web to be perforated a sawtooth knife, which rotates about an axis, and a counter-pressure roller on which the web to be perforated is running and in their grooves the teeth dipping the knife. Around Connectors different lengths to be able to produce is the distance of the knives to the axis around which they rotate variable. Consequently, must also the distances the counterpressure rollers to the axes about which the blades rotate be displaceable. This counterpressure roller set the back pressure for the perforation process ready. As a rule, they allow the knives to pass the tracks Pierce perforations without damaging the knives. For this purpose, mainly grooving or brushing rollers are used. At all Always apply an equal distance between two transverse perforations get are usually the counter-pressure rollers are moved together. For this purpose are all Counterpressure rollers on a support mounted relative to the machine frame, in which the axes, around which the blades rotate, are stored, is movable.
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 rotatable on the carrier which stored one ends of handlebars. The other ends of the handlebars are rotatably mounted in the machine frame, so that for the wearer parallelogram arises. For the purpose of moving the carrier is at this another lever mounted on which a drive acts. This drive is rotatable stored in the machine frame.
Als nachteilig ist jedoch anzusehen, dass eine solche Vorrichtung eine große Anzahl von Lagern benötigt und somit mechanisch aufwändig ist.When However, it is disadvantageous to see that such a device a size Number of bearings needed and thus mechanically complex is.
Aufgabe der Erfindung ist es daher, eine Vorrichtung vorzuschlagen, die mechanisch einfacher gehalten ist.task The invention is therefore to propose a device which is mechanically simpler.
Die Aufgabe wird gelöst durch das kennzeichnende Merkmal des Anspruchs 1.The Task is solved 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.Accordingly, the carrier is substantially displaceable along a line which lines the Ge gearing rollers and the axes around which the associated blades rotate, connects.
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 are between the carrier and the machine frame arranged linear guide means, whose guide direction is substantially parallel to the line which the axes of Counterpressure roller and the axes of rotation around which the blades rotate, connects. In this way it is possible the counter-pressure rollers in the radial direction on the axes of rotation of the knife to move.
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.Especially It is advantageous if the guide means attached to the carrier Include running rails, which are mounted in on the machine frame guides are stored displaceably. Such guides allow the Displacement of the carrier without a big one Effort. When using several rails and guides is also a canting of the carrier excluded, so that all counter-pressure rollers a precisely uniform Keep distance to the axis of rotation of the blades.
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 Further embodiment of the invention, a linear drive is provided, with which of the carriers is movable relative to the machine frame. Here are different Drives 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 driven by a motor Spindle spindle nut combination through which the rotational movement the motor axis over 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.One embodiment The invention is based on the subject description and the drawings.
