Description

  • Die Erfindung betrifft eine Vorrichtung zur Herstellung eines Vlieses aus Endlosfäden gemäß dem Oberbegriff des Patentanspruchs 1, und außerdem befaßt sich die Erfindung mit einem aus Endlosfäden hergestellten mehrlagigem Vlies. The invention relates to a device for producing a web of continuous filaments according to the preamble of claim 1, and further the invention is concerned with a product obtained from multi-ply non-woven filaments.
  • Durch die DE-PS 17 85 158, GB-PS 12 82 176 und GB-PS 12 97 582 sind schon Vorrichtungen zur Herstellung eines Vlieses aus Endlosfäden bekannt. DE-PS 17 85 158, GB-PS 12 82 176 and GB-PS 12 97 582 already apparatus for producing a nonwoven of continuous filaments are known. Dabei wird aus einer Schmelze und aus Spinndüsen eine Fadenschar mit Hilfe eines gasförmigen Treibmittels abgezogen, und die einzelnen Fäden werden auf einem Ablageband zur Bildung des Vlieses abgelegt. In this case, a yarn sheet is pulled off with the aid of a gaseous propellant from a melt and from the spinneret, and the individual filaments are deposited on a deposition belt to form the nonwoven.
  • Ein bedeutendes Qualitätsmerkmal bei den Vliesen sind ihre Gleichmäßigkeit und ihre Festigkeit, wobei die Festigkeit bzw. die Verhältnisse der Festigkeiten von Längsrichtung zu Querrichtung im wesentlichen durch den Ablegewinkel der einzelnen Fäden - Ablegerichtung in Bezug auf die Produktionsrichtung - bestimmt wird. An important quality characteristic in the nonwovens are their uniformity and their strength, the strength or the ratios of strengths of longitudinal direction to cross direction substantially through the depositing angle of the individual yarns - is determined - deposition direction with respect to the production direction.
  • Üblich ist schon die Verwendung von Spinnbalken mit einer Vielzahl von einzelnen Abzugsrohren für die Fäden, wobei jedem Abzugsrohr ein Separator zugeordnet ist. is already common, the use of spin beam having a plurality of individual flues for the threads, with each vent pipe is associated with a separator. Der Separator erfüllt die Aufgabe, die Filamente von der Beschleunigungsluft zu trennen und das Fadenbündel gleichzeitig zu spreizen. The separator fulfills the task to separate the filaments of the acceleration air and to spread the fiber bundle simultaneously. Durch diese Spreizung wird zugleich auch der Ablegewinkel vorgegeben. Through this spread and the deposit angle is also given.
  • Bei der Verwendung von Separatoren muß in der Praxis berücksichtigt werden, daß sich die einzelnen Separatoren wegen der austretenden Beschleunigungsluft gegenseitig stark beeinflussen. When using separators must be considered in practice that each other greatly influence the individual separators because of the emerging acceleration air. Deshalb gibt es hier nur eine einmalig zu wählende günstige Einstellung der Separatoren, durch die dann auch die Ablegerichtung zwangsläufig vorgegeben ist. Therefore, there is only a one-time favorable adjustment to dial the separators, the discharge direction is determined necessarily by then. Es besteht daher nur eine sehr eingeschränkte Möglichkeit, unterschiedliche Ablagewinkel zu realisieren. Therefore, there is only a very limited possibility to realize different deviation angle.
  • Wenn man im übrigen die Winkelstellung der einzelnen Separatoren tatsächlich geringfügig verändern wollte, um unterschiedliche Ablagewinkel zu ermöglichen, müßte die gesamte Vorrichtung zunächst abgeschaltet werden, da solche Änderungen im laufenden Betrieb einer Anlage nicht möglich sind. If you wanted to change the angular position of the individual separators actually slightly in the other to allow different deviation angle, the entire device must first be turned off, since such changes during operation of a plant are not possible. Außerdem sind mit der Änderung der Ablagewinkel erhebliche Ausschußmengen des produzierten Vlieses verbunden. In addition, substantial amounts Committee of the web produced are associated with the change in the angle of deposit.
  • Es ist auch schon vorgeschlagen worden, in Produktionsrichtung gesehen zwei Spinnbalken mit Separatoren im Abstand voneinander anzuordnen, wobei jedem Spinnbalken eine eigene Ablegerichtung der Filamente zugeordnet ist. It has also been proposed, as seen in the direction of production to arrange two spinning beam with separators spaced from one another, each spin beam is assigned its own discharge direction of the filaments. Man kommt dann zu einer sogenannten Kreuzablage mit zwei jeweils vorgegebenen Ablagewinkeln. then we arrive at a so-called cross tray with two respective predetermined deviation angles.
  • Wie voranstehend erwähnt, beeinflussen sich die einzelnen Separatoren aber gegenseitig wegen der austretenden Beschleunigungsluft, so daß man nur mit einer einmalig zu wählenden günstigen Einstellungen der Separatoren arbeiten kann, wodurch dann die Ablegerichtung zwangsläufig vorbestimmt ist. As mentioned above, the individual separators but affect each other because of the exiting air acceleration so that you can only work with a single to be elected favorable settings of the separators, which then causes the discharge direction is predetermined inevitable. Somit lassen sich bei dieser vorgeschlagenen Lösung mit zwei Spinnbalken nur begrenzte Ablegerichtungen bei der Kreuzablage realisieren. Thus, only limited deposition directions in the cross-Storage can be realized in this proposed solution with two spinning beams. Im übrigen ist es auch hier bei einer gewünschten Veränderung der Ablegewinkel erforderlich, die gesamte Vorrichtung zunächst abzuschalten, was zu den voranstehend schon genannten Nachteilen führt. Incidentally, it is also at a desired change in the deposit angle necessary to shut down the entire device at first, leading to the above already mentioned disadvantages.
  • Je nach Verwendungszweck des Vlieses besteht in der Praxis aber ein Bedürfnis nach unterschiedlichen Festigkeitswerten in unterschiedlichen Richtungen, und diesem Bedürfnis kann mit der vorgeschlagenen Lösung mit zwei Spinnbalken nicht nachgekommen werden. Depending on the intended use of the nonwoven fabric is in practice, however, a need for different strength values ​​in different directions, and this need can not be met with the proposed solution with two spinning beams.
  • Bei einer weiteren Vorrichtung zur Herstellung eines Vlieses aus Endlosfäden ist auch schon das sogenannte Vorhangverfahren zur Anwendung gekommen, bei welchem auf die oben erwähnten vielen Abzugsrohre verzichtet und auch keine Spreizvorrichtung (Separatoren) verwenden werden. In another apparatus for producing a nonwoven of continuous filaments so-called curtain method is also already been used, in which the above-mentioned many discharge tubes omitted and no expanding device (separators) are used. Die einen flächigen Vorhand bildende Fadenschar erstreckt sich senkrecht zur Produktionsrichtung, dh, die bevorzugte Ablegerichtung läuft parallel zur Produktionsrichtung. The forehand a sheet forming yarn sheet extending perpendicular to the production direction, that is, the preferred deposition direction running parallel to the production direction.
  • Die hierbei in jedem Fall höhere Geschwindigkeit der Filamente relativ zur Geschwindigkeit des Ablegebandes führt zu schlangenförmigen Bewegungen bei der Ablage der Filamente. The higher this case in any event, velocity of the filaments relative to the speed of the depositing band leads to serpentine movements during deployment of the filaments. Dabei kommt es dann in bestimmten Bereichen zu Überlagerungen einzelner Filamente. It is then in certain areas overlapping of individual filaments.
  • Ein mit einer solchen Vorrichtung hergestelltes Vlies besitzt zwar eine bevorzugte Festigkeit in Längsrichtung, also in Produktionsrichtung, allerdings sind die Festigkeitswerte in Querrichtung extrem schlecht. Although a product manufactured with such a device nonwoven has a preferable strength in the longitudinal direction, ie in the direction of production, however, the strength values ​​in the transverse direction are extremely poor.
  • Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche die Herstellung eines Vlieses mit einer hohen Gleichmäßigkeit erlaubt, und welche es gestattet, vorgegebene Festigkeits- und Dehnungswerte des Vlieses in gewünschten Richtungen zu realisieren. The invention has for its object to provide a device which allows the production of a nonwoven fabric having a high uniformity, and which makes it possible to achieve predetermined strength and elongation values ​​of the nonwoven fabric in desired directions.
  • Dieses Ziel erreicht die Erfindung bei der im Oberbegriff des Anspruchs 1 genannten Vorrichtung durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1. This object reaches the invention in defined in the preamble of claim 1 device by the features of the characterizing part of patent claim 1.
  • Durch die Verstellbarkeit mindestens eines Spinnbalkens lassen sich die Ablagewinkel auf beliebige Werte einstellen, und ein besonderer Vorteil besteht darin, daß eine solche Einstellung während des laufenden Betriebes der Vorrichtung möglich ist. Due to the adjustability of at least one spinning beam, the deviation angle can be set to any values, and a particular advantage is that such an adjustment during operation of the device is possible.
  • Bevorzugt sind Ablagewinkel zwischen jeweils 0° bis 45° und entgegengesetzt, also von 0° bis -45°, so daß die Ablagerichtungen der Filamente des ersten Spinnbalkens und des zweiten Spinnbalkens untereinander einen Winkel von kleiner oder gleich 90° im Sinne einer variablen Kreuzablage bilden. Deviation angle between each 0 ° to 45 ° and opposite, that is, from 0 ° to -45 °, so that the offset direction of the filaments of the first spinneret and the second spinneret with one another form an angle of less than or equal to 90 ° in terms of a variable cross-tray are preferably ,
  • Ein mit der erfindungsgemäßen Vorrichtung hergestelltes Vlies kann sowohl isotrope Eigenschaften besitzen als auch bevorzugte Längsfestigkeiten. A product produced with the inventive apparatus nonwoven fabric may have both isotropic properties and preferred longitudinal strength. Es sind auch bevorzugte Querfestigkeiten ohne Beeinträchtigung der Vliesgleichmäßigkeit, je nach Wahl der Ablagewinkel, möglich. There are also preferred transverse strength without affecting the fabric uniformity, depending on the choice of filing angle possible.
  • Durch die Erfindung soll ferner ein aus endlosfäden hergestelltes mehrlagiges Vlies geschaffen werden, welches wählbare Festigkeitswerte und eine hohe Gleichmäßigkeit besitzt. The invention provides a multi-ply non-woven made from continuous filaments further seeks to provide, which selectable resistance values ​​and a high uniformity has. Dieses Ziel erreicht die Erfindung gemäß den Merkmalen des Patentanspruchs 7. This aim achieved according to the invention the features of patent claim 7.
  • Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen und der Beschreibung angegeben sowie der Zeichnung zu entnehmen. Expedient refinements and advantageous developments of the invention are given in the subclaims and in the description and shown in the drawing.
  • Nachfolgend wird die Erfindung anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. The invention is further illustrated by the shown in the drawings embodiment. Es zeigen: Show it:

    eine perspektivische Darstellung eines Spinnbalkens gemäß Fig. 6. a perspective view of a spinning beam according to Fig. 6.
  • Fig. 1 zeigt eine als Ganzes mit der Bezugsziffer 10 bezeichnete Spinnstation, die zwei in Transportrichtung 30 (Produktionsrichtung) im Abstand voneinander angeordnete Spinnbalken 12 und 14 umfaßt. Fig. 1 is a designated as a whole by the reference numeral 10 spinning station comprising two spaced in the transport direction 30 (the direction of production) in spaced spinning beams 12 and 14. Über Schmelzleitungen 16 wird eine Schmelze zu den Spinnplatten 18 geführt. About melt conduits 16, a melt is conducted to the spinning disks 18th
  • Jede Spinnplatte 18 dient der Verteilung der Schmelze über die Produktionsbreite, also der Breite eines Ablagebandes 28. Die Spinnplatten 18 sind im untersten Teil der Spinnbalken 12, 14 auswechselbar angebracht. Each spinning plate 18 serves to distribute the melt to the production width, so the width of a storage tape 28. The spin plates 18 are in the lowest part of the spin beams 12 mounted replaceable fourteenth In der Spinnplatte 18 befindet sich eine varibale Anzahl von als Spinndüse bezeichneten Löchern, durch die die flüssige Spinnschmelze aus der Spinnplatte 18 als Fadenschar 50 nach Art eines Vorhangs austritt. In the spin plate 18, a number of varibale called spinneret holes through which the liquid spinning melt exits the spinning plate 18 as the yarn sheet 50 in the manner of a curtain is located. Dabei bewegt sich die Fadenschar 50 längs einer Blaswand 20, die eine Verstreckungszone 22 zum Verstrecken der Fadenschar bildet. Here, the yarn sheet 50 moves along a blowing wall 20 which forms a drawing zone 22 for stretching of the yarn sheet.
  • Die Spinnstation 10 umfaßt ferner bei den beiden Spinnbalken 12, 14 jeweils eine Fadenabzugsvorrichtung 24 und eine Ablegevorrichtung 26, durch welche die Fäden zur Erzielung einer hohen Gleichmäßigkeit gespreizt und auf dem in Transportrichtung 30 bewegten Ablageband 28 zur Bildung eines Vlieses 52 abgelegt werden. The spin station 10 further includes a respective thread removal apparatus 24 and a collection device 26, through which spread the filaments to achieve high uniformity and deposited on the moving in the transport direction 30 laydown belt 28 to form a web 52 in the two spinning beam 12, 14th
  • Das hier verwendete Vorhangverfahren arbeitet also mit einer Spreizvorrichtung - vergleichbar den bekannten Separatoren - um eine bestimmte Ablegerichtung der Fäden zu erzielen, nämlich eine 90°-Richtung, bezogen auf den Spinnbalken. So the curtain method used here works with a spreading - comparable to the known separators - to a certain discharge direction of the threads to achieve, namely a 90 ° direction with respect to the spin beam. Die Fäden werden also bis 90° zum Spinnbalken oszillierend hin- und herbewegt. The threads are so oscillating back to 90 ° to the spinning beam and forth.
  • Wie in Fig. 1 zu erkennen ist, erfolgt die Ablage zunächst bei dem Spinnbalken 12, und auf die dadurch gebildete erste Schicht wird beim anderen Spinnbalken 14 eine zweite Schicht abgelegt, wodurch ein mehrlagiges Vlies 52 entsteht. As can be seen in Fig. 1, the tray takes place initially at the spinneret 12, and the thus formed first layer a second layer is deposited in the other spinning beam 14, whereby a multi-ply nonwoven is formed 52nd
  • In der Draufsicht in Fig. 2 ist zu erkennen, daß die Spinnbalken 12, 14 aus ihrer parallel zueinander verlaufenden gestrichelt gezeichneten Lage heraus in Richtung der Pfeile 56 und 58 um ihre Drehachsen 34 verschwenkbar sind, wobei die Längsachsen 32 der Spinnbalken 12, 14 hier einen Winkel 54 bilden. In the plan view in Fig. 2 it can be seen that the spinning beam 12, 14 extending from their parallel dashed line position can be pivoted out in the direction of arrows 56 and 58 about their axes of rotation 34, wherein the longitudinal axes 32 of the spinning beam 12, 14 here form an angle 54th Die einzelnen Lagen des Vlieses 52 besitzen also die durch die Spinnbalken 12 und 14 vorgegebenen unterschiedlichen Ablagerichtungen bzw. Ablagewinkel. The individual layers of the batt 52 thus have the predetermined by the spinning beam 12 and 14 different directions or storage tray angle. Diese unterschiedlichen Ablagerichtungen sind in Fig. 3 - 5 dargestellt. These various tray are directions in Fig 3 - represented. 5. Fig. 3 zeigt den Ablageverlauf 36 des einen Spinnbalkens 12, während Fig. 4 den Ablageverlauf 38 des anderen Spinnbalkens 14 wiedergibt. Fig. 3 shows the course of storage 36 of a spinning beam 12, while Fig. 4 shows the shelf 38 of course other spinning beam 14 reflects. Das daraus bei dem mehrlagigen Vlies 52 sich ergebende Ablagebild 40, welches durch Überlagerung der Ablageverläufe 36 und 38 entsteht, ist in Fig. 5 dargestellt. The resulting multi-layer nonwoven 52 in the resulting image storage 40, which is formed by superimposing the tray curves 36 and 38 is shown in Fig. 5. Wie man erkennen kann, kreuzen sich die einzelnen Ablageverläufe, so daß sich für das mehrlagige Vlies insgesamt eine Kreuzablage mit variablen Winkeln ergibt. As can be seen, cross the individual deposition patterns so that total cross-rack with variable angles obtained for the multi-ply fleece. Wenn die sich kreuzenden Ablageverläufe 36 und 38 bei dem Ablagebild 40 an den Kreuzungsstellen einen Winkel von 90° bilden, erhält man ein isotropes Vlies 52 mit in allen Richtungen gleichen Festigkeitswerten. If the intersecting storage curves 36 and 38 form an angle of 90 ° at the intersection points in the image storage 40, to obtain an isotropic nonwoven 52 with the same in all directions strength values.
  • Der nähere Teilaufbau einer Spinnstation 10 ergibt sich aus Fig. 6, welche den Spinnbalken 12 in einer Draufsicht zeigt. The more detailed structure of a part of the spinning station 10 is shown in FIG. 6, which shows the spinning beam 12 in a plan view. Der Spinnbalken 12 ist - ebenso wie der Spinnbalken 14 - auf einem Drehgestell 42 angeordnet und mittels der Führungsrollen 46 längs kreisförmiger Führungsschienen 44 gehalten und geführt. The spinning beam 12 is - as well as the spinning beam 14 - arranged on a bogie 42, and held and by means of guide rollers 46 along guide rails 44 circular performed. Die Führungsschienen 44 ermöglichen eine Drehung des Spinnbalkens 12 um die zentrale Drehachse 34, so daß sich unterschiedliche Drehwinkel 48 realisieren lassen. The guide rails 44 permit rotation of the spinning shaft 12 about the central axis of rotation 34, so that different angles of rotation can be realized 48th Durch entsprechende Ausrichtung der beiden Spinnbalken 12 und 14 ist es also möglich, unterschiedliche Ablageverläufe 36 und 38 (vgl. Fig. 3 und 4) zu realisieren. By appropriate orientation of the two spinning beams 12 and 14, it is thus possible to deposit different profiles 36 and 38 (see FIG. FIGS. 3 and 4) to realize. Damit besteht die Möglichkeit, dem hergestellten Vlies 52 die der späteren Anwendung entsprechenden Festigkeitswerte zu geben. This makes it possible, 52 to give the fleece produced the subsequent use appropriate strength.
  • Die Führung und Halterung des Spinnbalkens 12 auf den Führungsschienen 44 ist auch in der perspektivischen Darstellung gemäß Fig. 7 verdeutlicht, und es ist hervorzuheben, daß die Einstellung unterschiedlicher Drehwinkel 48 auch während des laufenden Betriebes der gesamten Spinnstation 10 möglich ist. The guidance and retention of the spinning beam 12 on the guide rails 44 is also illustrated in the perspective view of Fig. 7, and it is emphasized that the adjustment of different rotation angle 48 10 is possible even during operation of the entire spinning station. Dies stellt in der Praxis einen erheblichen Vorteil dar, weil darauf verzichtet werden kann, die Spinnstation für die Einstellung neuer gewünschter Drehwinkel 48 und damit für die Erzeugung neuer Ablagebilder 40 abzuschalten und stillzulegen. This is in practice a significant advantage because it can be waived off and shut down the spinning station for hiring new desired angle of rotation 48 and thus for the creation of new storage images 40th
  • Insgesamt läßt sich die Spinnstation 10 demnach variabel betreiben, weil während des laufenden Betriebes der Spinnstation eine Kreuzablage mit variablen Winkeln erzielt werden kann. Overall, the spinning station can be operated variable 10 Accordingly, because during operation of the spinning station cross shelf with variable angles can be achieved. Man kann deshalb während des laufenden Betriebes sofort ein gewünschtes neues Vlies-Produkt erzeugen. Therefore, one can produce a desired new nonwoven product during operation immediately.
