Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen der Verbindungsnähte von mindestens zwei sich überlappenden Lagen von Folien aus insbesondere faserigen Werkstoffen, wie Papier od. dgl., mittels in Ultraschallschwingungen versetzter Sonotroden. Eine solche Vorrichtung dient vorzugsweise für die Ausbildung von Verpackungen oder Verpackungsbehältnissen beliebiger Form, z. B. Aufgußbeuteln. The invention relates to a device for producing the connecting seams of at least two overlapping layers of foils made of, in particular, fibrous Materials such as paper or the like, by means of ultrasonic vibrations Sonotrodes. Such a device is preferably used for the formation of packaging or packaging containers of any shape, e.g. B. Infusion bags.

Die Erfahrung hat gezeigt, daß bei der Herstellung solcher Verbindungsnähte mittels rollen- oder scheibenartiger Sonotroden (deutsche Auslegeschrift 1 156 303, »Industrie-Anzeiger«, Essen, Nr. 7, 1963) häufig Nahtstellen entstehen, die nicht nur nicht genügend fest sind, sondern auch noch brüchig sein können, so daß mit einer solchen Naht versehene Verpackungsbehältnisse unbrauchbar sind oder werden. Derartige fehlerhafte Stellen treten vielfach dort auf, wo die Naht, z. B. bei Faltbeuteln, über unterschiedlich große Lagendicken geführt ist. Experience has shown that in the production of such connecting seams by means of roller or disk-like sonotrodes (German Auslegeschrift 1 156 303, »Industrie-Anzeiger«, Essen, No. 7, 1963) often seams arise that do not just not strong enough, they can also be brittle, so that with Packaging containers provided with such a seam are or become unusable. Such defective points often occur where the seam, e.g. B. for folding bags, is performed over different thicknesses of layers.

Nun ist es zwar bekannt (deutsches Patent 629 842), zum Verheften von Papierblättern dieselben zwischen geriffelten oder gezahnten Hefträdern hindurchzuführen und zur Entlastung dieser Heftnaht neben derselben eine parallel verlaufende Sicke zu erzeugen. Die bei der hier erfolgenden Ineinanderverzahnung der Papierlagen erzielbare Festigkeit der Heftnaht ist jedoch zu gering, um z. B. bei Aufgußbeuteln ein sicheres Halten der Verbindungsnähte zu gewährleisten. Now it is known (German patent 629 842) for stapling of paper sheets to pass them between corrugated or toothed stapling wheels and to relieve this stitching seam next to it a parallel bead to create. The achievable with the interlocking of the paper layers taking place here Strength of the stitching seam is too low, however, to z. B. with infusion bags a safe one Ensure that the connecting seams are held in place.

Ferner ist (deutsche Auslegeschrift 1 115 120) eine Vorrichtung zum Gummieren von Materialfolien bekannt, mit der zwecks Herstellung von Klebstoffverbindungsnähten diese Nähte nicht mehr ununterbrochen ausgebildet, sondern in einer Reihe von kleinflächigen Verbindungsstellen aufgeteilt werden sollen, falls gewünscht wird, daß die jeweilige Naht z. B. durchlässig für Gas oder Flüssigkeiten sein soll oder geringere Ansprüche an ihre Festigkeit gestellt werden bzw. ein leichteres Lösen der gebildeten Nähte beabsichtigt ist. Furthermore (German Auslegeschrift 1 115 120) is a device for Known gumming of material foils with the purpose of producing adhesive connection seams these seams are no longer formed continuously, but rather in a series of small areas Joints should be divided, if it is desired that the respective Seam z. B. should be permeable to gas or liquids or lower demands to their strength or an easier loosening of the seams formed is intended.

Schließlich ist es bekannt, Werkstoffe durch Punktschweißung, und zwar auch unter Anwendung von Ultraschall miteinander zu verbinden (»Nachrichtentechnik«, Nr. 11 [1961], Heft 10; deutsche Patentschrift 330 570 ; »Ultrasonics«, Jan./März 1964; »Kunststoff-Rundschau«, 1962, Februar). Soweit es sich dabei um die Verwendung von Papier handelt, wird dasselbe entweder mit einer Kunststoffolie verbunden, oder aber es werden Papiere miteinander verschweißt, die je nach der angestrebten Festigkeit der Naht einen mehr oder weniger großen Wachsauftrag auf ihrer Oberfläche erhalten. Finally, it is known to spot weld materials, and to be connected to one another using ultrasound (»communications engineering«, No. 11 [1961], issue 10; German Patent 330 570; "Ultrasonics," January / March 1964; "Kunststoff-Rundschau", 1962, February). As far as the use is about paper, it is either connected with a plastic film, or but papers are welded together, depending on the desired strength the seam receive a more or less large amount of wax on its surface.

Die Erfindung hat sich daher die Aufgabe gestellt, eine Vorrichtung der eingangs genannten Art so auszubilden, daß gleichmäßigere und zerreißfestere Verbindungsnähte entstehen, die auch von wechselnden Lagendicken weitgehend unabhängig sind. The invention has therefore set itself the task of providing a device of the type mentioned in such a way that they are more uniform and more tear-resistant Connection seams are created that are largely independent of changing layer thicknesses are.

Die Lösung dieser Aufgabe besteht darin, daß die Arbeitsfläche der Sonotroden bei der eingangs genannten Vorrichtung erfindungsgemäß in eine Vielzahl von im Verhältnis zur Gesamtfläche der Naht kleine, durch Vertiefungen voneinander getrennten Flächeneinheiten aufgeteilt ist. Diese Lösung ergibt den Vorteil, daß eine Unterbrechung der Rißbildung (infolge der Versprödung) und darüber hinaus die Bildung einer elastischen Zone zwischen den Schweißflächen gewährleistet ist, so daß sich eine zwar durchlässige, aber gegen unbeabsichtigtes Lösen, insbesondere beim Eintauchen von Teebeuteln in Wasser, gesicherte Naht erzielen läßt. The solution to this problem is that the work surface of the Sonotrodes in the above-mentioned device according to the invention in a plurality of small in relation to the total area of the seam, by indentations from each other is divided into separate units of area. This solution has the advantage that an interruption in the formation of cracks (as a result of embrittlement) and, moreover, the Formation of an elastic zone between the welding surfaces is guaranteed so that one is permeable, but against unintentional loosening, in particular when immersing tea bags in water, a secure seam can be achieved.

Vorteilhaft weisen gemäß einem weiteren Erfindungsmerkmal die Flächeneinheiten der Sonotroden eine ballige Oberfläche auf. Ferner können gemäß vorteilhafter weiterer Erfindungsmerkmale die Flächeneinheiten der Sonotroden rechteckig oder parallelogrammförmig ausgebildet und zur Längsachse der Sonotroden schräg angeordnet sein. Ein weiteres vorteilhaftes Erfindungsmerkmal bezieht sich darauf, daß mehrere Reihen von versetzt zueinander angeordneten Flächeneinheiten auf den Sonotroden vorgesehen werden. According to a further feature of the invention, the surface units advantageously have the sonotrodes have a convex surface. Furthermore, according to advantageous further Features of the invention, the surface units of the sonotrodes are rectangular or parallelogram-shaped designed and arranged obliquely to the longitudinal axis of the sonotrodes. Another one advantageous feature of the invention relates to the fact that several rows of offset surface units arranged to one another are provided on the sonotrodes.

Die erfindungsgemäß hergestellten Nähte ergeben in jedem Fall auf Grund praktischer Erfahrungen bei wirtschaftlicher Fertigung eine wenn auch nicht gasdichte, so doch sehr gleichmäßig feste und zumindest auch streudichte Verbindung, wobei die Qualität der Verbindungsnaht auch nicht mehr von einer genauen Einhaltung der Frequenz und Amplitudengröße der Ultraschallschwingungen abhängig ist, wie das bei den bisherigen Herstellungsverfahren der Fall war. Es hat sich in der Praxis herausgestellt, daß die Flächenbemessung der einzelnen Naht- bzw. The seams produced according to the invention give up in any case Based on practical experience in economical production one if not gas-tight, yet very evenly solid and at least also leak-tight connection, whereby the quality of the connection seam also no longer depends on exact compliance the frequency and amplitude size of the ultrasonic vibrations depends, like that was the case with previous manufacturing processes. It turned out to be in practice pointed out that the area dimensioning of the individual seam resp.

Sonotrodeneinheiten vorteilhaft zwischen 1 und 5 mm2 liegt.Sonotrode units is advantageously between 1 and 5 mm2.

Nachstehend wird die Erfindung an Hand schematischer Zeichnungen einiger Beispiele von erfindungsgemäß ausgebildeten Verbindungsnähten sowie einer scheibenförmigen Sonotrode der erfindungsgemäßen Vorrichtung erläutert. Es zeigen Fig. 1 bis 3 drei verschiedene Beispiele von Ausschnitten einer mit der erfindungsgemäßen Vorrichtung hergestellten einfachen Überlappungsnaht, F i g. 4 die schaubildliche Darstellung einer scheibenförmigen Sonotrode zur Verwendung bei einer Vorrichtung zur Herstellung einer weiteren Nahtform und Fig. 5 einen vergrößerten Ausschnitt des Sonotrodenumfanges entsprechend der strichpunktierten Einkreisung V der F i g. 4. The invention is described below with reference to schematic drawings some examples of connecting seams designed according to the invention as well as one disc-shaped sonotrode of the device according to the invention explained. Show it 1 to 3 three different examples of excerpts one with the one according to the invention Device produced simple overlap seam, F i g. 4 the graphical one Representation of a disc-shaped sonotrode for use in a device for producing a further seam shape and FIG. 5 shows an enlarged section of the sonotrode circumference according to the dash-dotted encirclement V of F i G. 4th

In F i g. 1 bis 3 sind zwei Folienlagen oder -bahnen 1 und 2 so übereinandergelegt, daß sie sich einfach überlappen. Diese Bahnen 1 und 2 sind lediglich an den Flächenteilen 3 bzw. 4 bzw. 6 mittels einer in Ultraschallschwingungen versetzten Sonotrode fest miteinander verbunden, deren Arbeitsfläche in eine Vielzahl von im Verhältnis zur Gesamtfläche der Naht kleine, durch Vertiefungen voneinander getrennte Flächeneinheiten aufgeteilt ist (F i g. 4 und 5). Derartige Sonotroden können je nach der Art und Länge der Verbindungsnaht sowie des verwendeten Folienmaterials und der Art und Form des mit der Naht zu versehenden Körpers, z. B. einer Verpackung, als Scheiben, Walzen, Stempel u. dgl. ausgebildet sein. Ebenfalls je nach den vorgenannten Bedingungen weisen die Nahtteile 3, 4, 6 unterschiedliche Umrißformen auf und sind z. B. quadratisch, parallelogrammartig, rhombisch oder rechteckig ausgebildet, ohne daß hierdurch eine Beschränkung gegeben sein soll, da auch sonst denkbare Umrißformen von Fall zu Fall gewählt werden können. In Fig. 1 to 3, two layers or webs of film 1 and 2 are placed one on top of the other so that that they simply overlap. These tracks 1 and 2 are only on the surface parts 3 or 4 or 6 by means of a sonotrode set in ultrasonic vibrations connected to each other, their work surface in a variety of relative to Total area of the seam small units of area separated from one another by indentations is divided (Figs. 4 and 5). Such sonotrodes can, depending on the type and Length of the connection seam as well as the film material used and the type and Shape of the body to be provided with the seam, e.g. B. a packaging, as discs, Rollers, stamps and the like. Also depending on the aforementioned conditions the seam parts 3, 4, 6 have different outline shapes and are z. B. square, parallelogram-like, rhombic or rectangular, without this resulting in a Restriction should be given, since otherwise conceivable outlines from case to case can be chosen.

Diese Flächenteile der Verbindungsnähte sind in Nahtlängsrichtung reihenweise angeordnet, wobei auch mehrere Reihen nebeneinanderliegend vorgesehen sein können. Je nach der Umrißform dieser These surface parts of the connecting seams are in the longitudinal direction of the seam Arranged in rows, several rows also being provided next to one another could be. Depending on the outline of this

Flächenteile können letztere von Reihe zu Reihe oder in ein und derselben Reihe auch gegeneinander versetzt werden. Bei der in F i g. 2 dargestellten einreihigen Naht sind die Flächenteile 4 derselben in Form länglicher Parallelogramme ausgebildet. Hierdurch ergibt sich der Vorteil, daß die zwischen den Flächenteilen4 befindlichen Streifenteile 5 verhältnismäßig lang ausfallen, so daß eine bessere Nahtdichtheit erreicht wird. Für besondere Ansprüche an die Dichtheit der Naht, z. B. bei der Herstellung von Verpackungen für Mehl oder andere pulverige Güter werden die in Fig. 3 gegeneinander versetzt angeordneten Flächenteilreihen 6 hergestellt, so daß eine Art Labyrinthdichtung vorliegt.Surface parts can be the latter from row to row or in one and the same Row can also be offset against each other. In the case of the in FIG. 2 single row shown At the seam, the surface parts 4 of the same are designed in the form of elongated parallelograms. This has the advantage that those located between the surface parts4 Strip parts 5 turn out to be relatively long, so that a better seam tightness is achieved. For special demands on the tightness of the seam, e.g. B. at the Manufacture of packaging for flour or other powdery goods are the in Fig. 3 produced offset rows of surfaces 6 arranged offset from one another, so that there is a kind of labyrinth seal.
