Abstract

An apparatus for producing a fleece of thermoplastic polymer fibers comprises a melt-blown fiber spinneret (1) which produces a bundle (4) of fibers. A screening machine (2) is positioned below the spinneret and its distance from it is adjustable. There is an endless screen (3) in the machine on which the random fiber bundle is laid down as a fleece by smoothing surfaces (6, 7) above a vacuum chamber (5). The screening machine together with its smoothing surfaces can be pivoted from the horizontal plane.

Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen einer Vliesbahn aus thermoplastischen Polymerfilamenten, mit einem die Polymerfilamente als Filamentstrang vertikal nach unten abgegebenen Düsenkopf, insbesondere in Form eines Melt-Blown-Blaskopfes, und mit einer unter dem Düsenkopf angeordneten Siebbandmaschine mit einem endlos umlaufenden Siebband, auf dem der Filamentstrang im Bereich einer mit einem Saugkasten ausgerüsteten Ablagefläche in Wirrlage der Polymerfilamente als Vlies ablegbar ist, wobei die Sieb­ bandmaschine relativ zum Düsenkopf höhenverstellbar ist.The invention relates to a device for manufacturing a nonwoven web made of thermoplastic polymer filaments, with the polymer filaments as a filament strand vertically nozzle head emitted downwards, in particular in the form of a Melt blown die, and with one under the die head arranged screen belt machine with an endless rotating Screen belt on which the filament strand in the area with a suction box equipped storage space in the confused position of the Polymer filaments can be deposited as a fleece, the sieve tape machine is adjustable in height relative to the nozzle head.

Bei aus der Praxis bekannten, druckschriftlich nicht näher belegten Vorrichtungen der genannten Art ist eine Beein­ flussung des inneren Strukturaufbaus der Vliesbahn nur in sehr engen Grenzen möglich. Das gilt erst recht für be­ kannte Vorrichtungen der genannten Art (DE 40 14 413 A1), bei denen die Siebbandmaschine nicht relativ zum Düsenkopf höhenverstellbar ist.Not known in writing from known in practice occupied devices of the type mentioned is a leg flow of the internal structure of the nonwoven web only in very narrow limits possible. This applies all the more to be known devices of the type mentioned (DE 40 14 413 A1), where the screen belt machine is not relative to the nozzle head is adjustable in height.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß Vliesbahnen mit in weiten Grenzen unterschiedlichem, innerem Struktur­ aufbau hergestellt werden können.The invention has for its object a device of the type mentioned in such a way that nonwoven webs with a wide range of internal structures construction can be manufactured.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß die Siebbandmaschine zusätzlich mit ihrer Ablagefläche gegenüber einer Horizontalebene verschwenkbar gelagert ist.The solution to this problem according to the invention consists in that the sieve belt machine additionally with its storage area is pivotally mounted relative to a horizontal plane.

Die Erfindung geht hierbei von der Tatsache aus, daß Verän­ derungen der Relativlage von Düsenkopf und Siebbandma­ schine, durch Variation sowohl des Abstandes als auch der gegenseitigen Winkelstellung überraschenderweise erhebliche Eigenschaftsveränderungen der Vliesbahnen zur Folge haben, so daß ohne große Schwierigkeiten Produkte mit vorgegebenen Eigenschaften, z. B. für die Filtertechnik bestimmte Vliese hoher Weichheit, hoher Bauschigkeit, hohen Tuffs und dreidimensionaler Struktur, erzeugbar sind.The invention is based on the fact that changes changes in the relative position of the nozzle head and sieve belt by varying both the distance and the  mutual angular position surprisingly considerable Result in changes in the properties of the nonwoven webs, so that products with given can be used without great difficulty Properties, e.g. B. certain nonwovens for filter technology high softness, high bulk, high tuffs and three-dimensional structure, can be generated.

In konstruktiver Hinsicht kann der erfindungsgemäße Gedanke auf unterschiedliche Art und Weise weiter ausgestaltet werden. So kann der Düsenkopf um eine vertikale Achse relativ zur Siebbandmaschine drehbar gelagert sein. Weiterhin kann die Ablagefläche in Vorbewegungsrichtung des Siebbandes durch Einsatz entsprechender Leitbleche einen gekrümmten und einen daran anschließenden ebenen Bereich aufweisen und die Siebmaschine in Vorbewegungsrichtung des Siebbandes vor- und zurückverstellbar sein; auf diese Weise können wahlweise der gleichsam als starre Saugwalze funktionierende Bereich, der anschließende gerade Bereich oder auch beide Bereiche als Ablagefläche genutzt werden. In diesem Zusammenhang ergeben sich weitere Beeinflussungsmöglichkeiten, wenn der Saugkasten in seinem der Ablagefläche zugeordneten oberen Teil als Lade mit austauschbaren Einschüben ausgebildet ist. Im übrigen empfiehlt die Erfindung, die Anordnung so zu treffen, daß das Siebband in einer Seitenansicht rautenförmig über eine Antriebswalze, eine Steuerwalze, eine Umlenkwalze und die Ablagefläche geführt ist; hierbei ergibt sich nämlich eine sehr vereinfacht zu realisierende Bandsteuerung.In terms of construction, the idea of the invention can further developed in different ways become. This allows the nozzle head to move around a vertical axis be rotatably mounted relative to the belt machine. Furthermore, the storage surface in the direction of advance of the Sieve belt by using appropriate baffles curved and an adjoining flat area have and the screening machine in the direction of advance of Sieve belt be adjustable back and forth; in this way can optionally be used as a rigid suction roller working area, the subsequent straight area or both areas can be used as storage space. There are more in this context Options for influencing when the suction box in his the upper part assigned to the storage area as a drawer exchangeable inserts is formed. Furthermore recommends the invention to make the arrangement so that the sieve belt in a side view diamond-shaped over a Drive roller, a control roller, a deflection roller and the Storage space is guided; this results in a Belt control to be implemented very simply.
