Abstract

The assembly to produce a nonwoven web, of melt spun thermoplastic synthetic filaments, has a continuous and permeable conveyor belt to take the filaments extruded from the spinneret. A suction channel with a rectangular cross section is under the upper level of the belt, with a suction inlet across the belt width. A swing guide flap (8) is at both longitudinal edges (7) at the suction inlet (5), along the total length (L) of the inlet (5). They are aligned towards the upper level (4) of the permeable laying belt (2), and swing on the inlet edges (7). Both guide flaps (8) have a setting adjustment independent of each other. At least one flap (8) is a solid plate, and at least one flap (8) is a perforated plate. A rounded profile (9) is fitted to the upper edges of each guide flap (8). An operating mechanism (10) moves the guide flaps (8) into position. The suction unit (6) has an adjustable suction fan.

Description

Die Erfindung betrifft eine Anlage für die Herstellung einer Spinnvliesbahn aus Kunststoffilamenten, mit einem Spinnkopf, aus dessen Spinndüsenbohrungen die Kunststoffilamente aus thermoplastischem Kunststoff austreten, und mit einem endlos umlaufenden Ablegesiebband, auf dem die Kunststoffilamente zur Spinnvliesbahn abgelegt werden, wobei im Ablegebereich der Kunststoffilamente unter dem Obertrum des Ablegesiebbandes ein einen rechteckigen Querschnitt aufweisender Ansaugkanaleintritt einer Luftabsaugeinrichtung angeordnet ist und der Ansaugkanaleintritt eine etwa der Breite des Ablegesiebbandes entsprechende Länge aufweist.The invention relates to a plant for the production a spunbonded web made of plastic filaments, with a Spinning head, from whose spinneret holes the plastic filaments emerge from thermoplastic, and with an endless rotating sieve belt on which the plastic filaments to be deposited to the spunbonded web, in which Storage area of the plastic filaments under the upper strand of the Depositing belt a rectangular cross-section Intake duct entry of an air suction device is arranged and the intake duct entry is about the Width of the deposit screen belt has a corresponding length.

Bei bekannten Anlagen der genannten Art (DE 43 12 419 C2) können die Strömungs- bzw. Druckverhältnisse im Ablegebereich der Kunststoffilamente regelmäßig nur durch Veränderung der Einstellung des Sauggebläses der Luftabsaugeinrichtung beeinflußt werden.In known systems of the type mentioned (DE 43 12 419 C2) the flow or pressure conditions in the placement area the plastic filaments regularly only through change the setting of the suction fan of the air extraction device to be influenced.

Der Erfindung liegt die Aufgabe zugrunde, anzugeben, wie man mit verhältnismäßig einfachen konstruktiven Mitteln zwecks leichterer Beeinflussung der Vliesstoffherstellung eine größere Varianz der Strömungs- und Druckverhältnisse im Ablegebereich der Kunststoffilamente erreichen kann.The invention has for its object to indicate how one with relatively simple constructive means in order to influence the manufacture of nonwovens more easily a greater variance in flow and pressure conditions can reach the plastic filaments in the deposit area.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß an den beiden Längsrändern des Ansaugkanaleintrittes jeweils eine sich über die gesamte Länge des Ansaugkanaleintrittes erstreckende, zum Obertrum des Ablegesiebbandes hin gerichtete und um den zugeordneten Längsrand verschwenkbare Leitklappe angelenkt ist.The solution to this problem according to the invention consists in that at the two longitudinal edges of the intake duct inlet one each over the entire length of the intake duct inlet extending to the upper run of the lay-off belt directed towards and pivotable about the associated longitudinal edge Guide flap is articulated.

Die Erfindung geht hierbei von der Überlegung aus, daß die angestrebte Vergrößerung der Varianz der Strömungs- und Druckverhältnisse im Ablegebereich der Kunststoffilamente dadurch erreicht werden kann, daß man die Gestalt des Ansaugkanaleintrittes variabel gestaltet. Dies ermöglichen am einfachsten die verschwenkbaren Leitklappen, mit deren Hilfe die Größe und Lage des Ansaugkanaleintrittes in weiten Grenzen verändert werden können.The invention is based on the consideration that desired increase in the variance of the flow and Pressure conditions in the deposit area of the plastic filaments can be achieved by changing the shape of the Intake duct inlet designed variably. Make this possible the easiest are the pivotable guide flaps, with their Help the size and location of the intake duct inlet in wide limits can be changed.

Nach bevorzugter Ausführungsform der Erfindung sind die beiden Leitklappen unabhängig voneinander einstellbar. Die Leitklappen selbst können aus einem geschlossenen oder vorzugsweise gelochten Blech bestehen; eine Kombination eines geschlossenen Bleches am einen Längsrand mit einem gelochten Blech am anderen Längsrand ist ebenfalls möglich. Der Einsatz gelochter Bleche führt nämlich zu einem weiteren Beeinflussungsparameter, nämlich einem definierten Nebensaugluftstrom, dessen Richtung und Größe ebenso wie beim Hauptluftstrom durch die Stellung der Leitklappen verändert werden kann. Zur Vermeidung von unerwünschten Luftströmen sollten die freien oberen Längsränder der Leitklappen ein aufgesetztes Rundprofil aufweisen. Vorzugsweise sind den Leitklappen Betätigungsaggregate zugeordnet. Im übrigen empfiehlt es sich natürlich, in der Luftabsaugeinrichtung ein einstellbares Sauggebläse zu verwenden. According to a preferred embodiment of the invention two guide flaps can be set independently of each other. The Guide flaps themselves can be closed or preferably perforated sheet exist; a combination of one closed sheet metal on one longitudinal edge with a perforated sheet on the other longitudinal edge is also possible. The use of perforated sheets leads to one further influencing parameters, namely a defined one Subsidiary airflow, its direction and size as well changed in the main air flow by the position of the guide flaps can be. To avoid unwanted air flows should the free upper longitudinal edges of the guide flaps have an attached round profile. Preferably are assigned to the guide flap actuators. in the the rest, it is of course recommended to use the air extraction device to use an adjustable suction fan.
