Abstract

Ultrasonic vibrator beams down at an acute angle to a PTFE coated non-stick roller on the far side of the moving textile web and cover material, so that the roller rotates and the energy heats and fluidises plastic adhesive granules and thus bonds the textiles and cover together as they are moved by feed rollers before and behind the non-stick roller. Several vibrators with coupled ultrasonic heads can be used, overlapped as required, to cover wide material.

Description

Verfahren -urid Einrichtung zum Verkleben von aus einer fortlaufenden Bahn angeordneten Textilien mittels Ultraschall Es ist bekannt, daß man mittels Ultraschall Kunststoffteile erwärmen und miteinander verschweißen kann. So lassen sich auch Kleidungsstücke und ähnliche Textilien mittels eines passenden Kunststoffklebers, der sich unter Ultraschalleinwirkung-erwärmt, miteinander verkleben-. Bei den bekannten Verfahren dieser Art werden.jedoch im -allgemeinen nur relativ schmale und kurze Nähte gebildet. Die Fläche dieser Schweißnähte ist bei den bisherigen Verfahren verhältnismäßig klein und beträgt wohl selten.mehr als etwa 10 cm2. Da die zu verklebenden Teile eine gewisse Zeit im UltraschallfeM verbleiben müssen, um die erforderliche Temperatur zu erreichen, ist ein kontinuierliches Arbeiten bisher nicht möglich.Method -urid device for gluing from a continuous Web arranged textiles by means of ultrasound It is known that one means Ultrasound can heat plastic parts and weld them together. Let it be clothing and similar textiles can also be attached using a suitable plastic adhesive, which heat up under the action of ultrasound, stick together. With the known Procedures of this kind are generally only relatively narrow and short Seams formed. The area of these weld seams is the same as in the previous methods relatively small and is probably rarely more than about 10 cm2. Because the to be glued Parts have to remain in the ultrasound machine for a certain period of time in order to achieve the required To reach temperature, continuous work has not yet been possible.

Aufgabe der Erfindung ist es, ein Verfahren. und eine Einrichtung zum Verkleben-'vonauf einer fortlaufenden Bahn angeordneten Textilien mittels Ultraschall bereitzustellen, womit es möglich ist, die Bahn im kontinuierlichen Durchlauf zu erwärmen nn4 die Textilien zu verkleben bzw. zu Fixieren.The object of the invention is to provide a method. and a facility for gluing-'of textiles arranged on a continuous web by means of ultrasound provide, with which it is possible to the web in a continuous run heat nn4 to glue or fix the textiles.

Das erfindungsgemäe Verwahren ist dadurch gekennzeichnet, daß die Textilbahn kontinuierlich zwischen einer mit Ultraschalifrequenz schwingenden Sonotrode und einer Gegenfläche durchgeführt wird.The storage according to the invention is characterized in that the Textile web continuously between a sonotrode that vibrates at an ultrasonic frequency and a mating surface is carried out.

Es hat sich überraschenderweise gezeigt, daß bei langsamem Durchziehen der Textilbahn durch den Arbeitsspalt zwischen Sonotrode und Gegenfläche (vorzugsweise mit Hilfe von Förderwalzen) eine ausreichende Einwirkung des Ultraschalls stattfindet1 um den zwischen den zu verklebenden Teilen befindlichen Kunststoffkleber auf die Erweichungs- und Verklebungstemperatur zu erhitzen.It has surprisingly been found that when pulled through slowly the textile web through the working gap between the sonotrode and the counter surface (preferably with the help of conveyor rollers) there is sufficient exposure to the ultrasound 1 around the plastic adhesive located between the parts to be glued to the Heat softening and sticking temperature.

Noch inniger wird die Berührung zwischen der schwingenden Sonotrode und der Textilbahn bzw. den auf ihr liegenden, zu verklebenden Teilen, wenn die Sonotrode relativ zu der Gegenfläche so angeordnet ist, daß die Hauptschwingungsrichtung der Sonotrode im Arbeitsspalt einen spitzen Winkel mit der~ Gegenfläche bildet. Durch diese Anordnung wir erreicht, daß eine Komponente der Ultraschall schw- Igungen parallel zu der Textilbahn verläuft und die Textilbahn (vorzugsweise im Verein mit äußeren Fördermitteln) aLlmählich weiterfördert. Dadurch findet eine sehr intensive Ultraschall einwirkung statt.The contact between the vibrating sonotrode becomes even closer and the textile web or the parts to be glued lying on it, if the Sonotrode is arranged relative to the counter surface so that the main direction of oscillation the sonotrode forms an acute angle with the opposite surface in the working gap. With this arrangement we achieve that one component of the ultrasound oscillations runs parallel to the textile web and the textile web (preferably in association with external funding) will gradually be further promoted. This takes place very intense Ultrasonic exposure instead.

Die Gegenfläche kann an einer ebenen Platte ausgebildet sein, über welche die Textilbahn läuft. Die Achse der sonotrode verläuft dann schräg zu dieser Platte.The mating surface can be formed on a flat plate, over which the textile web runs. The axis of the sonotrode then runs obliquely to this Plate.

Vorzugsweise b-ildet aber die Gegenfläche den Mantel einer außermittig zu der Sonotrode angeordneten, frei drehbaren Walze. Vor und hinter dieser Walze können in bekannter Weise Förderwalzen für die Textilbahn angeordnet sein.Preferably, however, the opposing surface forms the jacket of an eccentric freely rotatable roller arranged to the sonotrode. In front of and behind this roller can be arranged in a known manner conveyor rollers for the textile web.

Ist die Textilbahn zu breit, um von einer Sontrode bestrichen zu werden, so kann man mehrere Sonotróden, die je durch einen schmalen -Luftspalt getrennt sind, nebenèinarnder -anordnen.If the textile web is too wide to be covered by a Sontrode, so you can have several sonotrods, each separated by a narrow air gap are to be arranged next to each other.

Dadurch kann praktisch ein beliebig breites B'and gleih'-zeitig erwärmt und verklebt bzw. verschweißt werden.As a result, a tape of any width can be heated at the same time and glued or welded.

Der Vorteil der Erfindung-für die Stoff' verklebung liegt vor allem darin, daß man wesentlich schneller als bei den bisher immer taktweise arbeitenden Pressen arbeiten kann. Ferner werden nicht der Stoff oder die Einlage erwärmt, sondern die zur Verklebung dienenden Kunststoffteilchen, die normalerweise in Form von Granulat-oder Punktbeschichtung zuvor auf die Einlage aufgebracht waren. Schließlich ist die Abkühlzeit so gering, daß man die Stoffe nach Verlassen der Verklebezone praktisch sofort weiter verarbeiten kann. Selbst die Kunststoffteilchen erwärmen sich vorwiegend von ihrer Oberflache aus.The advantage of the invention - for the fabric 'gluing lies above all in the fact that you can work much faster than with those who have always worked in cycles up to now Pressing can work. Furthermore, it is not the fabric or the insert that is heated, but rather the plastic particles used for bonding, normally in the form of granules or Point coating were previously applied to the insert. Finally, there is the cool down time so low that the fabrics can be continued practically immediately after leaving the bonding zone can handle. Even the plastic particles mainly heat up from them Surface off.

Hierin sind: Fig. 1 die schematische Darstellung einer erfindungsgemäßen Verklebeeinrichtung; Fig. 2 eine Draufsicht einer Anordnung mit drei nebeneinanderliegenden Sonotroden und Fig. 3 die schematische Darstellung eines anderen Ausführungs beispiels der Ertindung.Some exemplary embodiments of the invention are based on the following described in the drawing.

Diese werden auf einer Zuführungseir1richtung, die aus einer Rollenbahn, einem Fließband oder im einfachsten Fall aus einer ebenen Auflegetafel 6, aus Blech oder Kunststoff besteht, unter Zwischenlage eines Kunststoffgranulats oder eines ahnlichen, in der Wärme wirksam werdenden Klebemittels aufeinandergelegt Am Ende der Zuführungseinrich-tung 6 ist ein Förderwalzenpaar 3,4 übereinander angeordnet, Beispielsweise ist die Unterwalze 4 unverschieblich und nicht verstellbar arigeordnett während die Oberwalze 3 vorzugsweise f-ür die verschiedenen Stoffdicken in der Höhe verstellbar gelagert und - gefedert ist Es können eine oder beide Förderwalzen angetrieben sein.The textile web to be glued consists of the insert 1 and the outer fabric 2. These are on a Zuführseir1richtung, which consists of a roller conveyor, a Conveyor belt or in the simplest case from a flat lay-on board 6, from sheet metal or Consists of plastic, with the interposition of a plastic granulate or a similar one, in the heat effective adhesive placed on top of each other at the end of the feed device 6, a pair of conveyor rollers 3, 4 is arranged one above the other, for example the lower roller 4 immovable and not adjustable arigeordnett while the top roller 3 is preferred For the different fabric thicknesses, adjustable in height and mounted and - spring-loaded One or both conveyor rollers can be driven.

Dicht hinter den Förderwalzen 3,4 befindet sich eine Brei drehbare Walze 9. Diese ist mit einer nichthaftenden Beschichtung 10 versehen, wozu vorzugsweise PTFE verwendet wird. Die Walze 9 ist in der Hohe'verstellbar. Etwas außermitting versetzt über der Walze 9 befindet sich eine SorlotXrde 8. Die Sonotrode 8 ist über ein Anschlußgewinde 7 mit einem Ultraschallkopf 5 verbunden.Just behind the conveyor rollers 3, 4 there is a rotatable pulp Roller 9. This is provided with a non-stick coating 10, preferably for this purpose PTFE is used. The roller 9 is adjustable in height. Somewhat out of place There is a SorlotXrde 8 offset above the roller 9. The sonotrode 8 is above a connecting thread 7 is connected to an ultrasound head 5.

Dicht hinter der aus der sonotrode 8 und der Gegenwalze 9; bestehenden Ultraschalizone ist ein weiteres Förderwalzenpaar 11,12 angeordnet, dessen Abstand ebenfalls entsprechend der Stoff stärke im Abstand einstellbar ist. Dieses W,alzen- -paar ist ebenso wie das Walzenpaar 3,4 angetrieben Zwischen den Walzen sind jeweils Unterstützungsplatten 13 aus Blech oder Kunststoff zur Führung der Textilbahn vorgesehen Führt man dem Ultraschallkopf 5 HF-Energie zu, so führt die Sonotrode 8 entsprechende Schwingungen aus, die in der dargestellten Anordnung im wesentlicher, senkrecht zu der Textilbahn 1,2 verlaufen und durch den Doppelpfeil 14 angedeutet sind. Da die Mittellinie der Sonotrode 8 nicht durch den Mittelpunkt der Walze 9 geht, wird die Walze durch die schwingende sonotrode in drehende Bewegung versetzt. Um diese richtig einstellen zu können, ist vorzugsweise außer der Höhenverstellung auch eine horizontale Verstellmöglichkeit /von Waze 9 und Sonotrode 8 zueinander vorgesehen.Close behind the one from the sonotrode 8 and the counter roller 9; existing Another pair of conveyor rollers 11, 12 is arranged in the ultrasonic zone, the distance between them The distance can also be adjusted according to the fabric thickness. This W, alzen- -pair is driven just like the roller pair 3, 4 between the rollers are each Support plates 13 made of sheet metal or plastic are provided for guiding the textile web If the ultrasound head 5 is supplied with HF energy, the sonotrode 8 carries out the corresponding Vibrations, which in the arrangement shown are essentially perpendicular run to the textile web 1, 2 and are indicated by the double arrow 14. There the center line of the sonotrode 8 does not go through the center of the roller 9, will the roller is set in rotating motion by the oscillating sonotrode. Around To be able to adjust correctly is preferably also one in addition to the height adjustment horizontal adjustment / provided by Waze 9 and sonotrode 8 to each other.

Gelangen nun Oberstoff und Einlage -zwischen die lalze 9 und die Sonotrode 8, so wird einerseits, wie erwähnt, die Walze 9 in Drehbewegung versetzt, und andererseits wird der zwischen Oberstoff und Einlage befilldliche Kunststoff im Arbeitsspalt zwischen Sonotrode und Gegenfläche durch die Ultraschallschwingungen der Sonotrode erwärmt, bis er sich verflUssigt bzw. erweicht, wodurch die beiden Teile miteinander verbunden werden. Durch die Höhenverstellung der Walze S kann der jeweils erforderliche Anpressdruck eingestellt werden.Now the outer fabric and the insert get between the roller 9 and the sonotrode 8, on the one hand, as mentioned, the roller 9 is set in rotary motion, and on the other hand the plastic located between the outer fabric and the insert becomes in the working gap between the sonotrode and the counter surface by the ultrasonic vibrations the sonotrode is heated until it liquefies or softens, causing the two Parts are connected to each other. By adjusting the height of the roller S can the required contact pressure can be set.

Ist die Arbeitsbreite der Textilbahn größer als die Breite der zur Verfügung stehenden Sonotrode, so können mehrere Sonotroden nebeneinander angeordnet werden, wobei der Luftspalt zwischen ihnen sehr klein gemacht werden kann, z.P 0,1 bis 0,2 mm Dieser kleine Spalt wird sich in der Regel nicht auf dem Stoff abzeichnen.If the working width of the textile web is greater than the width of the Available sonotrode, several sonotrodes can be arranged next to one another the air gap between them can be made very small, e.g. 0.1 up to 0.2 mm This small gap will usually not show on the fabric.

Es können aber auch die Stirnseiten der Sonotroden so ausgebildet werden, daß sie sich gegenseitig uberlappen. So zeigt Fig. 2 ein Anordnungsbeispiel von drei nebeneinanderliegenden Sonotroden von oben gesehen ohne die Schallköpfe. In diesem Falle snd die beiden äußeren Sonotroden 15,17 mit einer schrXgliegenden Stirnf1che versehen, während die mittlere Sonotrode 16 zwei schrägliegende Stirnflächen hat, die im Winkel: genau zu denen, der äußeren Stirnflächen passen. Durch diese, SchrEglage wird erreicht, daß die Fuge zwischen je zwei Sonotroden sich in der Praxisnicht störend auswirkt.However, the end faces of the sonotrodes can also be designed in this way that they overlap each other. Thus, FIG. 2 shows an example of the arrangement of three adjacent sonotrodes seen from above without the transducers. In this case the two outer sonotrodes 15, 17 have an inclined one End face provided, while the middle sonotrode 16 has two inclined end faces has that at the angle: exactly to those that fit the outer end faces. Through this, An inclined position is achieved so that the joint between two sonotrodes does not move in practice has a disruptive effect.

Fig. 3 zeigt eine Anordnung ähnlich Fig. 1, bei der jedoch die Sonotrode 18 schräg zur Laufrichtung der Textilbahn 1,2 angeordnet ist und statt der Walze 9 eine ebene, an der Oberseite einer Platte i9 ausgebildete Gegenfläche 20 vorhanden ist. Die Hauptschwingungsrichtung 21 der Sonotrode 18 verläuft also nicht senkrecht, sondern unter einem sPitzen Winkel zu der ebenen Gegenfläche 20. Auf diese Weise kann ebenfalls eine langsame Förderung der Textilbahn durch die Ultraschallschwingungen f erreicht werden.Fig. 3 shows an arrangement similar to FIG. 1, but in which the Sonotrode 18 is arranged obliquely to the running direction of the textile web 1,2 and instead the roller 9 has a flat counter surface formed on the upper side of a plate 19 20 is present. The main oscillation direction 21 of the sonotrode 18 thus runs not perpendicular, but at an acute angle to the flat opposing surface 20. In this way, a slow promotion of the textile web through the can also Ultrasonic vibrations f can be achieved.
