Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Verfestigung und/oder Strukturierung von einem Vlies sowie eine Strukturschale.The present invention relates to a device for consolidating and/or structuring a fleece and a structural shell.
Bei der Wasserstrahlverfestigung von Vliesen, Geweben oder Gewirken, wird eine Flüssigkeit, wie beispielsweise Wasser, aus einer Vielzahl von Düsen gegen das zu verfestigende Material gespritzt wird. Das zu verfestigende Material läuft über eine sich drehende flüssigkeitsdurchlässige Trommel, die zum Absaugen des Wassers zusätzlich mit Unterdruck beaufschlagt sein kann. Üblicherweise besteht die Trommel aus einer zylindrischen massiven Basistrommel mit Bohrungen, die einen großen Wasserabfluss gewährleisten. Mit Abstand zur Basistrommel wird eine Strukturtrommel aufgezogen, die feinperforierte Öffnungen zur Verfestigung der Fasern aufweisen kann, dem zu bearbeitenden Material aber auch eine Oberflächenstruktur in Form eines Musters und/oder eine Perforierung von unterschiedlicher Geometrie verleihen kann.In the hydroentanglement of fleece, woven or knitted fabrics, a liquid such as water is sprayed from a large number of nozzles against the material to be bonded. The material to be solidified runs over a rotating, liquid-permeable drum, which can also be subjected to negative pressure to suck off the water. Usually, the drum consists of a cylindrical, solid base drum with holes that ensure a large water drainage. A structure drum is mounted at a distance from the base drum, which can have finely perforated openings for strengthening the fibers, but can also give the material to be processed a surface structure in the form of a pattern and/or perforations of different geometries.
Nach der
Weiterhin ist es bekannt, die Strukturschale entlang der Längsachse der Trommel zu teilen, also mehrere Segmente miteinander auf dem Umfang zu verbinden. Dies findet dann seine Grenze, wenn sich die Nahtstelle der Segmente nicht im Vlies wiederfinden darf. Ein weiterer Nachteil ist die Befestigung der Segmente untereinander, da die Segmente aus einem dünnen Blech bestehen und jede Veränderung über den Querschnitt zu einer unterschiedlichen Anlage auf der Strukturtrommel oder zu unerwünschten Abdrücken im Vlies führt.Furthermore, it is known to divide the structural shell along the longitudinal axis of the drum, ie to connect several segments to one another on the circumference. This then finds its limit when the interface of the segments must not be found in the fleece. Another disadvantage is the fastening of the segments to one another, since the segments consist of a thin metal sheet and any change across the cross-section leads to a different bearing on the structure drum or to undesired imprints in the fleece.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Verfestigung und/oder Strukturierung von einem Vlies zu schaffen, bei der die zuvor genannten Nachteile nicht auftreten. Weiterhin ist es Aufgabe der Erfindung, eine verbesserte Strukturschale mit deutlich vergrößerter Strukturhöhe für die Vorrichtung zur Verfestigung und/oder Strukturierung von einem Vlies zu schaffen.The invention is therefore based on the object of creating a device for consolidating and/or structuring a fleece in which the aforementioned disadvantages do not occur. Furthermore, the object of the invention is to create an improved structural shell with a significantly increased structural height for the device for consolidating and/or structuring a fleece.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale der Ansprüche 1 und 11.This problem is solved by the features of
Die Erfindung betrifft eine Vorrichtung zur hydrodynamischen Verfestigung und/oder Strukturierung von Vlies, umfassend eine besaugte drehende Trommel, eine mit Abstand auf der Trommel angeordnete Strukturschale, die von einem Vlies zumindest teilweise umschlingbar ist, sowie mindestens ein Wasserbalken, der einen Düsenstreifen mit einer Vielzahl von Düsen aufweist, wobei der Wasserbalken ausgebildet ist, mittels Wasserstrahlen das Vlies zu verfestigen und/oder zu strukturieren und/oder zu perforieren.The invention relates to a device for the hydrodynamic bonding and/or structuring of nonwovens, comprising a rotating drum subjected to suction, a structuring shell arranged at a distance on the drum and around which a nonwoven can be at least partially wrapped, and at least one water bar, which has a nozzle strip with a plurality of of nozzles, wherein the water bar is designed to solidify and/or structure and/or perforate the fleece by means of water jets.
Kerngedanke der Erfindung ist eine Strukturschale die aus mindestens zwei Ringen gebildet wird, die auf die Trommel aufschiebbar sind und befestigbar sind.The core idea of the invention is a structural shell that is formed from at least two rings that can be slid onto the drum and fastened.
Die Strukturschale wird aus mindestens zwei axial segmentierten Ringen gebildet, die über die Trommel mit Abstand aufgeschoben werden. Die Ringe können z.B. durch Lasersintern aus verschiedenen Materialien (Kunststoff, Metall) hergestellt werden. Dieses Verfahren erlaubt komplexere und höhere Geometrien als die bisherigen Ätzverfahren.The structural shell is formed from at least two axially segmented rings that are slid over the drum at a distance. The rings can be made of different materials, for example by laser sintering (plastic, metal) are produced. This process allows more complex and higher geometries than previous etching processes.
Natürlich sind auch Ringe denkbar, die mit anderen Fertigungsverfahren hergestellt werden, wie z.B. spanend, gegossen oder lasergeätzt.Rings that are manufactured using other manufacturing processes, such as machining, casting or laser-etching, are of course also conceivable.
Das axiale Segmentieren bietet die Möglichkeit des Einsatzes von Fertigungsverfahren, bzw. -maschinen, die sonst für die benötigte Arbeitsbreite, die bis zu 5,5 m betragen kann, nicht geeignet sind.The axial segmentation offers the possibility of using manufacturing processes or machines that are otherwise unsuitable for the required working width, which can be up to 5.5 m.
Erfindungsgemäß können die Ringe dauerhaft zu einer Schale gefügt werden, z.B. durch Kleben oder eine mechanische Verbindung, wie eine komplementäre Schwalbenschwanznut oder Feder/Nutanordnung an den Stirnseiten. Die einzelnen Ringe können zusammengesetzt werden und durch eine gemeinsame Oberflächenbeschichtung zu einer geschlossenen Strukturschale gefügt werden, (z.B. vernickeln), um die Trennfugen zu schließen. Die Verbindung der Ringe kann direkt oder indirekt miteinander stoffschlüssig, formschlüssig oder kraftschlüssig erfolgen.According to the invention, the rings can be permanently joined to form a shell, for example by gluing or a mechanical connection such as a complementary dovetail or tongue and groove arrangement on the faces. The individual rings can be put together and joined to form a closed structural shell by means of a common surface coating (e.g. nickel plating) in order to close the joints. The rings can be connected directly or indirectly to one another with a material fit, form fit or force fit.
Alternativ können die Ringe vereinzelt bleiben und z.B. axial oder radial auf der Trägertrommel verspannt werden. Weiterhin können auch Montageringe für die Stoßkanten der Ringe verwendet werden, die zumindest teilweise von den Ringen verdeckt werden, und mittels denen die Ringe durch Kleben oder mechanische Verbindung indirekt miteinander verbunden werden, beispielsweise durch integrierte Clipse an den Montageringen.Alternatively, the rings can remain isolated and, for example, be clamped axially or radially on the carrier drum. Furthermore, mounting rings can also be used for the abutting edges of the rings, which are at least partially covered by the rings and by means of which the rings are connected to one another indirectly by gluing or mechanical connection, for example by integrated clips on the mounting rings.
Die Ringe können mittel 3-D-Drucker hergestellt werden, wobei die Strukturierung der Oberfläche in einem einzigen Fertigungsschritt herstellbar ist. Die Strukturierung kann über die Schnittkante zum nächsten Ring hinausgehen, so dass eine Strukturschale ohne Trennfuge herstellbar ist.The rings can be produced using a 3D printer, with the structuring of the surface being able to be produced in a single production step. The structuring can go beyond the cut edge to the next ring, so that a structured shell can be produced without a parting line.

Durch die Spannelemente 26 mit den seitlichen Distanzelementen 25 ist eine variabel breite Anordnung der Strukturschale 11 möglich, die aus mindestens zwei Ringen bestehen kann, oder aus vielen Ringen, die zusammen die gesamte Trommel 10 überdecken. Damit kann die Anlage an die Breite der zu verarbeitenden Warenbahn angepasst werden, so dass der Energieeinsatz minimiert wird. Alternative Befestigungen für die Ringe sind im Rahmen der Erfindung möglich, beispielsweise ein Verspannen der Ringe zwischen Trommel und Ring mittels federbelasteten Spannelementen oder mechanischer Befestigung.The

Der Ring 12 weist abwechselnde Abschnitte 12c, 12d, 12e mit einer unterschiedlichen Strukturierung auf, so dass über die Breite des Ringes 12 entweder ein durchgehendes einheitliches Muster im Vlies entsteht, oder getrennte oder zusammenhängende Bereiche mit unterschiedlichen Mustern im Vlies herstellbar sind.The
Die Vergrößerung zeigt einen vergrößerten Ausschnitt eines Ringes 12 einer Strukturschale 11, der eine unterschiedliche Strukturierung und Perforierung aufweist. Im mittleren Abschnitt 12d ist eine Perforierung mit großen Löchern 18 angeordnet, die durch vorstehende Erhebungen 19 in Form von Quadraten voneinander getrennt sind. Die Quadrate können jede beliebige Höhe und Größe über der Grundfläche des Ringes aufweisen, und beispielsweise eine Höhe von 15 mm aufweisen. Bei entsprechender Gestaltung kann die Erhebung 19 in Kombination mit den Wasserstrahlen des Wasserbalkens 1 eine Perforierung im Vlies erzeugen. Die seitlichen Abschnitte 12c, 12e weisen dagegen ein kleines regelmäßiges Lochmuster auf.The enlargement shows an enlarged section of a
In der
Dadurch, dass die Strukturschale 11 durch mindestens zwei Ringe 12,13 gebildet wird, lassen sich Herstellverfahren verwenden, die für die gesamte Arbeitsbreite einer Trommel 10 zum Wasserstrahlverfestigen so nicht möglich ist. Insbesondere die Verfahren Lasersintern oder andere 3-D-Druck-Verfahren ermöglichen komplexe Oberflächenstrukturen, die mit dem klassischen Stanz- und/oder Ätzverfahren nicht möglich sind.Due to the fact that the
Werden die Ringe 12, 13, 14, 15 separat auf der Trommel 10 lösbar montiert, ergibt sich der Vorteil der leichten Montage und der flexiblen Anpassung an die Breite des zu verarbeitenden Vlieses. Die Ringe 12, 13, 14, 15 können mit unterschiedlicher Oberfläche in beliebiger Reihenfolge und Anordnung montiert werden, was die Herstellung von streifenförmigem Vlies sehr flexibel gestaltet. Der Wasserbalken 1 lässt sich dabei durch einen angepassten Düsenstreifen 2 der Strukturschale 11 anpassen, wobei im Bereich der Stirnkanten der Ringe der Düsenstreifen 2 Unterbrechungen 5 aufweist, damit sich keine Streifen im Vlies bilden.If the
Werden die Ringe 12, 13, 14, 15 nicht lösbar miteinander vorher oder auf der Trommel 10 miteinander montiert, ergibt sich eine nach der Montage einteilige Strukturschale 11, die aufgrund des Herstellverfahrens eine vielfältigere Oberflächenstruktur aufweisen kann, als dies mit einer einstückigen Strukturschale 11 möglich wäre. Ist beabsichtig, ein breites Vlies ohne Längsstreifen mit einer komplexen Oberflächenstruktur und/oder Perforierung herzustellen, können die einzelnen Ringe 12, 13, 14, 15 auch aneinandergefügt und die Oberfläche galvanisch beschichtet werden, beispielsweise vernickelt werden, so dass sich eine einteilige Strukturschale 11 aus einzelnen Ringen herstellen lässt. Diese hat den Vorteil, dass komplexe Oberflächenstrukturen möglich sind, ohne dass sich Längsstreifen aufgrund des Herstellverfahrens im Vlies abzeichnen. Der Düsenstreifen 2 kann entsprechend angepasst werden und mit oder ohne Unterbrechungen 5 ausgeführt werden.If the
