Description

Die Erfindung bezieht sich auf ein Verfahren zum Bearbeiten einer kontinuierlich vorlaufenden Materialbahn gemäß dem Oberbegriff des Anspruchs 1 und auf eine Vorrichtung zum Bearbeiten einer kontinuierlich vorlaufenden Materialbahn gemäß Oberbegriff des Anspruchs 2.The The invention relates to a method for processing a continuous leading material web according to the preamble of claim 1 and to an apparatus for processing a continuous leading material web according to the preamble of claim 2.

Eine derartige Vorrichtung geht beispielsweise aus der DE 44 39 284 C2 hervor.Such a device is for example from the DE 44 39 284 C2 out.

Die Bearbeitung besteht beispielsweise in der Verfestigung eines aus thermoplastischen Fasern bestehenden Vlieses durch stellenweises Verschmelzen der Fasern. Hierzu wird bei der Vorrichtung gemäß der DE 44 39 284 C2 die zu bearbeitende Materialbahn unter einer mittels einer dem Bearbeitungsspalt vorgelagerten und mit Abstand von der Gegenwalze angeordneten Umlenkwalze auf Spannung gehalten, so dass die Materialbahn die Gegenwalze über einen Winkel von ca. 90° umschlingt.The processing consists, for example, in the solidification of a nonwoven consisting of thermoplastic fibers by fusing the fibers in places. For this purpose, in the device according to the DE 44 39 284 C2 the material web to be processed is held under tension by means of a deflection roller arranged upstream of the machining gap and arranged at a distance from the counter-roller, so that the material web wraps around the counter-roller over an angle of approximately 90 °.

Zur Erzielung eines optimalen Bearbeitungseffektes sollte es zu keiner Relativbewegung zwischen der Gegenwalze und der Warenbahn kommen, da sonst die Gefahr besteht, dass der Bearbeitungsprozess durch schlupfbedingte Scherkräfte gefährdet wird.to Achieving an optimal editing effect should be nonexistent Relative movement between the counter roll and the web come, otherwise there is a risk that the machining process by slip-related shear forces endangered becomes.

Zwar ist es unter bestimmten Verfahrensparametern – wie Materialbahnspannung und Geschwindigkeit – möglich, mittels einer Vorrichtung gemäß der DE 44 39 284 C2 ein akzeptables Bearbeitungsergebnis zu erhaltne, es hat sich jedoch gezeigt, dass Abweichungen von diesen Verfahrensparametern zu einer erheblichen Verschlechterung des Arbeitsergebnisses führen können.Although it is possible under certain process parameters - such as web tension and speed - by means of a device according to the DE 44 39 284 C2 To obtain an acceptable processing result, it has been shown that deviations from these process parameters can lead to a significant deterioration of the work result.

Aus dem Patent US 4 400 227 ist bereits eine Laminiervorrichtung zum Herstellen einer Kunststoffbahn aus mehreren aufeinander geschichteten Kunststoffbahnen, insbesondere Folienbahnen aus thermoplastischen oder elastischen Kunststoffen, bekannt. Hierfür durchlaufen beispielsweise drei miteinander zu laminierende Bahnen gleichzeitig und übereinander einen Bearbeitungsspalt, der zwischen einer Sonotrode einer Ultraschallerzeugungseinheit und einer Gegenwalze gebildet wird. Die Sonotrode der Ultraschallerzeugungseinheit dient zum Verschmelzen der Bahnen untereinander in dem Bearbeitungsspalt. Die Gegenwalze ist zusätzlich als Prägewalze mit entsprechenden Vertiefungen und Hervorhebungen ausgebildet, um die einzelnen Bahnen nur in einem durch die Prägung der Walze vorherbestimmten Muster miteinander zu verbinden. Zur Unterstützung der Verschmelzungsvorganges der einzelnen Bahnen untereinander ist in Umlaufrichtung der Gegenwalze gesehen unmittelbar hinter dem Bearbeitungsspalt eine Rolle vorgesehen, die die Bahnen gegen die Gegenwalze drückt. Zusätzlich ist wiederum im Umlaufrichtung der Gegenwalze gesehen hinter der Rolle eine Andrückwalze angeordnet, die die Aufgabe hat, die weitergeführte fertig laminierte Materialbahn spannungsmäßig von dem Bearbeitungsspalt mit der Sonotrode zu trennen.From the patent US 4,400,227 A laminating device for producing a plastic web from a plurality of laminated plastic webs, in particular film webs of thermoplastic or elastic plastics, is already known. For this purpose, for example, three webs to be laminated together undergo simultaneously and one above the other a machining gap which is formed between a sonotrode of an ultrasound generating unit and a counter-roller. The sonotrode of the ultrasound generating unit serves to fuse the webs together in the machining gap. The counter roll is additionally formed as an embossing roller with corresponding recesses and highlights to connect the individual webs only in a predetermined by the embossment of the roller pattern. To support the merging process of the individual webs with each other seen in the direction of rotation of the counter roll immediately behind the machining gap, a roller is provided which presses the webs against the counter roll. In addition, again seen in the direction of rotation of the mating roll behind the roller, a pressure roller is arranged, which has the task of separating the further finished finished laminated material web tension of the machining gap with the sonotrode.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren bzw. eine Vorrichtung zum Bearbeiten einer kontinuierlich vorlaufenden Materialbahn derart weiterzubilden, dass die Vorrichtung weitestgehend unabhängig von der Wahl der Verfahrensparameter keinen negativen Einfluss auf das Bearbeitungsergebnis hat.Of the The invention is therefore based on the object, a method or a Device for processing a continuously leading material web in such a way that the device largely independent of the choice of process parameters no negative impact on the Has processing result.

Diese Aufgabe wird in ihrem verfahrensmäßigen Aspekt durch das in Anspruch 1 wiedergegebene Verfahren und in ihrem vorrichtungsmäßigen Aspekt durch die in Anspruch 2 wiedergegebene Vorrichtung gelöst.These Task is in its procedural aspect by the claim 1 reproduced method and in its device-related aspect solved by the reproduced in claim 2 device.

Dadurch, dass bei einem erfindungsgemäßen Verfahren mindestens eine Andrückwalze die Materialbahn vor und nach dem Durchlaufen des Bearbeitungsspaltes gegen die Gegenwalze andrückt, werden der Schlupf zwischen der Gegenwalze und der Materialbahn und die durch ihn in der Materialbahn hervorgerufenen Scherkräfte reduziert. Thereby, that in a method according to the invention at least one pressure roller the material web before and after passing through the machining gap against the counter roll presses the slip between the backing roll and the web and the reduced by him in the web caused shear forces.

Das Andrücken der Materialbahn gegen die Gegenwalze erfolgt durch Andrückwalzen -in Vorlaufrichtung der Materialbahn gesehen – vor und nach dem Durchlaufen des Bearbeitungsspaltes, so dass zwischen den Stellen des Andrucks ein Materialbahnbereich geschaffen wird, in welchem die Materialbahn die Gegenwalze nahezu frei von äußeren Zug- oder Scherkräften umschließt. In diesem Bereich wird die Materialbahn somit besonders effektiv gegen die Gegenwalze gedrückt und es kann ein besonders kontrollierter Bearbeitungsprozess der Materialbahn, der nahezu frei von äußeren Störungen ist, stattfinden.The press the web against the counter roll is done by pressure rollers seen in the feed direction of the material web - before and after passing through the machining gap, so that between the points of Andrucks a material web region is created, in which the material web the counter roll encloses almost free of external tensile or shear forces. In this Area, the material web is thus particularly effective against the Counter roll pressed and it can be a specially controlled machining process of Material web, which is almost free of external disturbances, take place.

Zur Durchführung des erfindungsgemäßen Verfahrens geeignet ist eine Vorrichtung mit einer eine Sonotrode aufweisenden Ultraschallerzeugungseinheit, mit einer der Sonotrode gegenüberliegenden und mit dieser den Bearbeitungsspalt, der von der Materialbahn durchlaufen wird, bildenden Gegenwalze, bei der zumindest eine Andrückwalze vor und nach dem Bearbeitungsspalt vorgesehen ist, die die Materialbahn gegen die Gegenwalze drückt.to execution the method according to the invention suitable is a device with a sonotrode having Ultrasonic generating unit, with one of the sonotrode opposite and with this the machining gap, which pass through the material web is, forming counter-roller, in front of the at least one pressure roller and after the machining gap is provided which the material web presses against the counter roll.

Hierdurch wird einerseits bewirkt, dass unterschiedliche Warenbahnspannungen nicht auch an der Verschweißstelle, d.h. im Bearbeitungsspalt anliegen, wodurch das Bearbeitungsergebnis bereits verbessert wird, andererseits wird durch diese Ausgestaltung die Warenbahn um einen gewissen Winkelbereich nahezu spannungsfrei um die Gegenwalze herum geschlungen, so dass hier durch Luft aus den zu verschweißenden Lagen herausgedrückt wird und das Ergebnis des Schweißprozesses somit nochmals verbessert werden kann.As a result, on the one hand causes that different web tension not at the welding point, ie in the machining gap lie, whereby the processing result is already improved, on the other hand, the web is wound by a certain angular range almost free of stress around the counter roll around, so that is pressed out here by air from the layers to be welded and thus the result of the welding process can be further improved ,

Um ein besonders effektives und gleichzeitig schonendes Andrücken der Materialbahn an die Gegenwalze bewirken zu können, empfiehlt es sich, die oder zumindest eine der Andrückwalzen mit einem nachgiebigen Walzenmantel auszustallen. Dies kann beispielsweise durch eine Gummierung konstruktiv bewerkstelligt werden.Around a particularly effective and at the same time gentle pressing of the To cause material web to the counter roll, it is recommended that or at least one of the pressure rollers with a yielding roll shell. This can be, for example be accomplished constructively by a rubber coating.

Ferner sieht eine besonders bevorzugte Ausführungsform vor, zumindest eine der Andrückwalzen als durchbiegesteuerbare Walze auszubilden. Durch diese Ausgestaltung ist es möglich, zu einer Verungleichmäßigung der Spaltbreite führenden Durchbiegungen der Gegenwalze zumindest teilweise zu kompensieren.Further provides a particularly preferred embodiment, at least one the pressure rollers as a deflection-controllable roller form. By this configuration Is it possible, to a divergence of the Gap width leading deflections the counter roll at least partially compensate.

Letzteres ist – wenn auch nur für einen begrenzten Durchbiegungswert der Gegenwalze – auch dann möglich, wenn die oder zumindest eine der Andrückwalzen bombiert ausgebildet sind.The latter is - if also only for a limited deflection value of the counter roll - even then possible, if the or at least one of the pressure rollers formed cambered are.

Ferner ist es zur Verringerung des Schlupfes und Reduzierung von Scherkräften in der Materialbahn während des Durchlaufens durch den Bearbeitungsspalt möglich, zumindest eine der Andrückwalzen anzutreiben.Further It is used to reduce slippage and reduce shear forces in the material web during the passage through the machining gap possible, at least one of the pressure rollers drive.

In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch dargestellt. Es zeigen:In the drawing are embodiments of Invention shown schematically. Show it:

1 eine Seitenansicht einer Ausführungsform der erfindungsgemäßen Vorrichtung sowie 1 a side view of an embodiment of the device according to the invention and

2 einen Schnitt nach Linie II-II in 1. 2 a section along line II-II in 1 ,

Die in 1 als Ganzes mit 100 bezeichnete Vorrichtung umfasst eine am Maschinengestell 1 feste, vertikale Geradführung in Gestalt einer Schwalben schwanzschiene 2, an der ein erster Schlitten 3 und ein zweiter, zusätzlicher Schlitten 4 im Sinne des Pfeiles 5 verschiebbar gelagert sind.In the 1 as a whole with 100 designated device comprises a on the machine frame 1 solid, vertical straight guide in the form of a swallow tail rail 2 at the first sled 3 and a second, additional sled 4 in the sense of the arrow 5 are slidably mounted.

An dem ersten Schlitten 3 ist eine Ultraschallerzeugungseinheit 6 fest angeordnet, die auf eine Sonotrode 7 wirkt, die radial gegen eine Gegenwalze 8, die hier als Reliefwalze ausgebildet ist, gerichtet ist. Zwischen der Stirnseite 7' der Sonotrode 7 und dem Umfang 8' der Gegenwalze 8 wird unter Belassung einer Spalthöhe 9 eine Materialbahn 10 hindurchgeführt, die beispielsweise aus einem Vlies aus thermoplastischen Fasern bestehen kann. Durch die hochfrequenten Kompressionen, die das Material zwischen den Scheiteln des Reliefs der Gegenwalze 8 und der Stirnseite 7' der Sonotrode erfährt, kommt es zu lokalen Temperaturerhöhungen bis zur Erweichung der thermoplastischen Fasern. Wenn es nur um eine Verfestigung eines Vlieses geht, muss die Erwärmung so dosiert werden, dass gerade ein Zusammenschmelzen der Fasern erfolgt, jedoch Durchbrüche im Material vermieden werden. Bei entsprechender Steuerung des Energieeintrags können solche Durchbrüche aber auch bewusst herbeigeführt werden, d.h. es kann nach dem Verfahren auch gelocht oder geschnitten werden. Der Energieeintrag, dem eine bestimmte Stelle im Material für die kurze Zeit des Passierens des Bearbeitungsspalts 11 zwischen der Sonotrode 7 und der Gegenwalze 8 ausgesetzt ist, ist also für den Bearbeitungseffekt durchaus kritisch. Dieser Energieeintrag hängt von der in dem Spalt 11 herrschenden Kraft ab. Es ist plausibel, dass sich die Wirkungen der Ultraschallschwingungen umso stärker bemerkbar machen, je fester die Materialbahn in dem Bearbeitungsspalt 11 zusammengedrückt wird.At the first sled 3 is an ultrasonic generating unit 6 firmly arranged on a sonotrode 7 acts radially against a counter roll 8th , which is designed here as a relief roller, is directed. Between the front side 7 ' the sonotrode 7 and the scope 8th' the counter roll 8th is leaving a gap height 9 a material web 10 passed, which may for example consist of a web of thermoplastic fibers. Due to the high-frequency compressions, the material between the crests of the relief of the backing roll 8th and the front side 7 ' the sonotrode experiences, it comes to local temperature increases to the softening of the thermoplastic fibers. If it is only a consolidation of a nonwoven, the heating must be dosed so that just a fusion of the fibers takes place, but breakthroughs in the material can be avoided. With appropriate control of the energy input such breakthroughs can also be deliberately brought about, ie it can also be perforated or cut by the method. The energy input to a particular location in the material for the short time of passing the machining gap 11 between the sonotrode 7 and the counter roll 8th is exposed, so is quite critical for the editing effect. This energy input depends on the in the gap 11 ruling power. It is plausible that the effects of the ultrasonic vibrations are all the more noticeable, the firmer the material web in the machining gap 11 is compressed.

Zwischen dem Schlitten 4 und dem Schlitten 3 ist ein Kraftmessglied in Gestalt einer Kraftmessdose 20 angeordnet, welches die von einem als Ganzen mit 25 bezeichneten Antrieb ausgeübte Kraft vollständig auf den Schlitten 3 überträgt und somit ein Signal abgibt, welches bis auf geringe Reibungsverluste an der Schwalbenschwanzschiene 2 die in dem Bearbeitungsspalt 11 gegen die Gegenwalze 8 wirkende Kraft repräsentiert.Between the sled 4 and the sled 3 is a force measuring element in the form of a load cell 20 arranged by one as a whole with 25 designated drive force completely on the carriage 3 transmits and thus emits a signal which, except for low friction losses on the dovetail rail 2 in the machining gap 11 against the counter roll 8th represents acting force.

Der als Ganzes mit 25 bezeichnete Antrieb umfasst einen Schrittmotor 12, der am Maschinengestell 1 abgestützt ist und ein Gewindestück 13 verdreht, wel ches über eine Gewindespindel 14 auf ein als Ganzes mit 15 bezeichnetes Kniegelenk wirkt, dessen unterer Schenkel 16 an dem zweiten Schlitten 4 und dessen oberer Schenkel 17 am Maschinengestell 1 gelagert sind. Die Anordnung aus Antrieb 25 und Kniegelenk 15 bilden Mittel 31, über die sich die Sonotrode 7 starr an dem Maschinengestell 1 abstützt. Der Schlitten 4 hält durch die Schrägstellung des Schenkels 16 sich ergebende seitliche Kraftkomponenten von der Kraftmessdose 20 fern.The whole with 25 designated drive includes a stepper motor 12 on the machine frame 1 is supported and a threaded piece 13 twisted, wel ches about a threaded spindle 14 on as a whole with 15 designated knee joint acts, the lower leg 16 on the second carriage 4 and its upper thigh 17 on the machine frame 1 are stored. The arrangement of drive 25 and knee joint 15 make up funds 31 about which the sonotrode 7 rigidly on the machine frame 1 supported. The sled 4 stops by the inclination of the thigh 16 resulting lateral force components of the load cell 20 remote.

Das Signal der Kraftmessdose 20 wird über die Leitung 21 einer Steuer- und Regeleinheit 30 zugeführt, die über eine Leitung 22 den Schrittmotor 12 steuert. Die Steuerung erfolgt so, dass die Kraft FS in dem Spalt im wesentlichen konstant gehalten wird. Dadurch bleibt auch der Bearbeitungseffekt insoweit im wesentlichen konstant, unabhängig davon, ob die Materialbahn 10 Dickenschwankungen aufweist, die Sonotrode 7 thermischen Dehnungen unterliegt oder die Walze 8 sich durchbiegt.The signal of the load cell 20 is over the line 21 a control unit 30 fed through a conduit 22 the stepper motor 12 controls. The control is such that the force F S is kept substantially constant in the gap. As a result, the processing effect also remains essentially constant, regardless of whether the material web 10 Has thickness variations, the sonotrode 7 thermal strains subject or the roller 8th it bends.

Um kurzzeitige, von der Sonotrode 7 auf das Maschinengestell 1 über die Mitten 31 in das Maschinengestell 1 eingeleitete Kraftspitzen, die eine negative Auswirkung des mit der Vorrichtung 100 erzielten Bearbeitungsergebnisses haben können, abzuleiten, ist zwischen dem Schlitten 4 und dem unteren Schenkel 16 eine Einrichtung 35 zur Aufnahme von Kraftspitzen vorgesehen, die als nachgiebiges Bauteil 36 ausgebildet ist. Wenn hier von „Nachgiebigkeit" die Rede ist, so sei hiermit zum Ausdruck gebracht, dass das Bauteil der Sonotrode ermöglichen soll, im Sinne des Pfeiles 5 geringfügig beim Auftreten einer Kraftspitze gemäß 1 nach oben auszuweichen.To short-term, from the sonotrode 7 on the machine frame 1 about the centers 31 in the machine frame 1 initiated force peaks, which have a negative impact of the device 100 can have deduced, is between the sled 4 and the lower leg 16 An institution 35 provided for receiving force peaks, as a resilient component 36 is trained. If this is "compliance", it is hereby expressed that the component of the sonotrode should allow, in the sense of the arrow 5 slightly when a force peak occurs according to 1 to escape upwards.

Bei dem in 1 dargestellten Ausführungsbeispiel besteht das Bauteil 36 aus einem Kunststoff, dessen Nachgiebigkeit temperaturabhängig ist. Zur Anpassung der Nachgiebigkeit ist eine ein Peltierelement umfassende Temperaturregeleinrichtung 37 vorgesehen, die entsprechend der Vorgaben über eine Leitung 21' von der Steuer- und Regeleinrichtung 30 mit elektrischer Spannung beaufschlagt wird.At the in 1 illustrated embodiment, the component 36 made of a plastic whose compliance is temperature-dependent. To adjust the compliance is a temperature control device comprising a Peltier element 37 provided according to the specifications via a line 21 ' from the control and regulating device 30 is applied with electrical voltage.

Bei der erfindungsgemäßen Vorrichtung 100 sind bezogen auf die Vorlaufrichtung der Materialbahn 10, die durch den Pfeil Q symbolisiert werden soll, Andrückwalzen 40, 41 vor und hinter dem Bearbeitungsspalt 1 vorgesehen, mit der die Materialbahn 10 gegen den Umfang 8' der Gegenwalze 8 mit einer Kraft in Richtung des Pfeiles FA, FA', die etwa in Richtung der Normalen der Tangente an der Andrückstelle verläuft drückt. Bei dem dargestellten Ausführungsbeispiel ist die Andrückwalze als durchbiegegesteuerte, nicht selbst angetriebene Walze ausgebildet.In the device according to the invention 100 are related to the feed direction of the web 10 , which is to be symbolized by the arrow Q, nip rollers 40 . 41 in front of and behind the machining gap 1 provided with the material web 10 against the scope 8th' the counter roll 8th with a force in the direction of the arrow F A , F A ', which extends approximately in the direction of the normal of the tangent at the pressure point. In the illustrated embodiment, the pressure roller is designed as a deflection-controlled, not self-driven roller.

Durch den Ausdruck der Materialbahn 10 gegen den Umfang 8' der Gegenwalze 8 vor und hinter dem Bearbeitungsspalt 11 mit den Andrückkräften FA' und FA wird die Materialbahn 10 über einen Winkelbereich α um die Gegenwalze 8 geschlungen. Da aufgrund der Andrückkräfte der Andrückwalzen 40, 41 Zugkräfte von der Materialbahn im Bereich α im wesentlichen ferngehalten werden, kann der Verschweißprozess im Bearbeitungsspalt im wesentlichen frei von äußeren Einflussgrößen wie Scher- und Reibungskräften erfolgen, wodurch das Bearbeitungsergebnis vergleichmäßigt wird.By the expression of the material web 10 against the scope 8th' the counter roll 8th in front of and behind the machining gap 11 with the pressure forces F A 'and F A is the material web 10 over an angular range α around the counter roll 8th looped. Because of the pressure forces of the pressure rollers 40 . 41 Tensile forces are kept substantially away from the web in the area α, the welding process in the machining gap can be made substantially free of external factors such as shear and frictional forces, whereby the machining result is made uniform.
