Abstract

Apparatus for the heat treatment of a length of continuously moving material in a plurality of treatment zones contains a fan to provide a stream of circulating air. The outer wall of the machine and fan housing is provided with an opening which can be closed by a closure device, through which the interior of the fan housing and the nozzle casing are accessible.

Description

Die Erfindung betrifft eine Vorrichtung (entsprechend dem Oberbegriff des Anspruches 1) zur Wärmebehandlung einer kontinuierlich bewegten Warenbahn.The invention relates to a device (according to the preamble of claim 1) for the heat treatment of a continuously moving web.

Vorrichtungen dieser Art finden insbesondere als Spannmaschinen zum Trocknen und Fixieren von textilen Warenbahnen Verwendung.Devices of this type are used in particular as tensioning machines for drying and fixing textile webs.

Da die in den einzelnen Behandlungszonen durch den Ventilator umgewälzte Luft zwangsläufig einen gewissen Anteil von Fasern und Fremdstoffen aufnimmt, die sich an gewissen Stellen des Strömungsweges, insbesondere im Bereich der Düsen und im Ventilatorgehäuse, absetzen, ist eine regelmäßige Reinigung der Düsen, des Ventilators und des Ventilatorgehäuses notwendig.Since the air circulated by the fan in the individual treatment zones inevitably absorbs a certain proportion of fibers and foreign substances that settle at certain points in the flow path, in particular in the area of the nozzles and in the fan housing, regular cleaning of the nozzles, the fan and of the fan housing is necessary.

Zu diesem Zweck muß bei den bisher bekannten Ausführungen (siehe z.B. die AT-B-329 498) der Innenraum des Maschinengehäuses durch im Maschinengehäuse vorgesehene Türen betreten werden. Die Düsen müssen zum Zwecke der Reinigung im allgemeinen ausgebaut und außerhalb des Maschinengehäuses gereinigt werden. Ebenso umständlich und zeitaufwendig erweist sich bei den bekannten Ausführungen der Zugang zum Innern des Ventilatorgehäuses und seine Reinigung.For this purpose, in the previously known designs (see, for example, AT-B-329 498), the interior of the machine housing must be entered through doors provided in the machine housing. For cleaning purposes, the nozzles must generally be removed and cleaned outside the machine housing. Access to the interior of the fan housing and its cleaning have also proven to be cumbersome and time-consuming in the known designs.

Der Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung dieser Mängel eine Vorrichtung der im Oberbegriff des Anspruches 1 vorausgesetzten Art so auszubilden, daß die Düsenkästen, der Ventilator und das Innere des Ventilatorgehäuses auf besonders einfache und zeitsparende Weise gereinigt werden können.The invention is therefore based on the object, avoiding these deficiencies, to design a device of the type required in the preamble of claim 1 in such a way that the nozzle boxes, the fan and the interior of the fan housing can be cleaned in a particularly simple and time-saving manner.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Appropriate embodiments of the invention are the subject of the dependent claims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht.An embodiment of the invention is illustrated in the drawing.

Die in der Zeichnung in einem Ausschnitt in perspektivischer Darstellung (teilweise aufgebrochen) veranschaulichte Spannmaschine zur Wärmebehandlung einer kontinuierlich bewegten Warenbahn enthält in einem Maschinengehäuse 1 eine Anzahl von in Bewegungsrichtung der Warenbahn aufeinanderfolgenden Behandlungszonen, von denen im folgenden die Behandlungszone 2 näher erläutert wird.The stretching machine for heat treatment of a continuously moving material web, illustrated in a detail in the drawing in a perspective view (partially broken away), contains in a machine housing 1 a number of treatment zones successive in the direction of movement of the material web, of which the treatment zone 2 is explained in more detail below.

Sie enthält einen durch einen Motor 3 angetriebenen Ventilator 4, der im unteren Bereich eines quaderförmigen Ventilatorgehäuses 5 angeordnet ist. Der Innenraum des Ventilatorgehäuses 5 ist an die Druckseite des Ventilators angeschlossen.It contains a fan 4 driven by a motor 3, which is arranged in the lower region of a cuboidal fan housing 5. The interior of the fan housing 5 is in the Pressure side of the fan connected.

Das Ventilatorgehäuse 5 ist auf der Innenseite einer Längswand des Maschinengehäuses 1 angeordnet, wobei die Ventilatorgehäuse von aufeinanderfolgenden Behandlungszonen jeweils an unterschiedlichen Längsseiten des Maschinengehäuses 1 vorgesehen sind.The fan housing 5 is arranged on the inside of a longitudinal wall of the machine housing 1, the fan housing of successive treatment zones being provided on different longitudinal sides of the machine housing 1.

Mit dem oberen Bereich des Ventilatorgehäuses 5 sind obere Düsenkästen 6 und untere Düsenkästen 7 verbunden. Über diese Düsenkästen wird die vom Ventilator umgewälzte Luft der zwischen den oberen und unteren Düsenkästen 6, 7 hindurchgeführten Warenbahn von oben und unten zugeführt.Upper nozzle boxes 6 and lower nozzle boxes 7 are connected to the upper region of the fan housing 5. Via these nozzle boxes, the air circulated by the fan is fed from above and below to the web of material passed between the upper and lower nozzle boxes 6, 7.

Zur Rückführung der die Warenbahn verlassenden Luft dient ein im oberen Bereich des Maschinengehäuses 1 angeordneter, in der Zeichnung nicht sichtbarer Rückluftkanal, der zur Saugseite des Ventilators 4 führt und in dem üblicherweise Filter- und Heizeinrichtungen vorgesehen sind. In diesen Rückluftkanal tritt die Luft durch ein Sieb 8 ein, das durch einen Schlitz in der Seitenwand des Maschinengehäuses 1 zum Zwecke der Reinigung nach außen herausziehbar ist.A return air duct, which is arranged in the upper region of the machine housing 1 and is not visible in the drawing, is used to return the air leaving the web, which leads to the suction side of the fan 4 and in which filter and heating devices are usually provided. The air enters this return air duct through a sieve 8, which can be pulled out through a slot in the side wall of the machine housing 1 for the purpose of cleaning.

Die der benachbarten Längswand des Maschinengehäuses 1 zugekehrte äußere Längswand des Ventilatorgehäuses 5 ist in ihrem oberen Bereich mit einer Öffnung 9 versehen, die durch ein (nicht veranschaulichtes) Verschlußorgan verschließbar ist und durch die der Innenraum des Ventilatorgehäuses 5 und die Düsenkästen 6 und 7 zu Reinigungszwecken von außen zugänglich sind.The outer longitudinal wall of the fan housing 5 facing the adjacent longitudinal wall of the machine housing 1 is provided in its upper region with an opening 9 which is closed by a (not ) Closing member is closable and through which the interior of the fan housing 5 and the nozzle boxes 6 and 7 are accessible from the outside for cleaning purposes.

Zu diesem Zweck ist das Maschinengehäuse 1 im Bereich der Öffnung 9 des Ventilatorgehäuses 5 mit einer Öffnung 10 versehen, die durch eine schwenkbare Türe 11 verschließbar ist und durch die das Verschlußorgan der Öffnung 9 des Ventilatorgehäuses zugänglich ist.For this purpose, the machine housing 1 is provided in the region of the opening 9 of the fan housing 5 with an opening 10 which can be closed by a pivotable door 11 and through which the closure member of the opening 9 of the fan housing is accessible.

Wie die Zeichnung erkennen läßt, reicht die im Ventilatorgehäuse 5 vorgesehene Öffnung 9 bis zum oberen Rand des Gehäuses 5 und erstreckt sich damit über den gesamten Höhenbereich der Eintrittsöffnungen der Düsenkästen 6 und 7. Mittels eines durch die Öffnung 9 des Ventilatorgehäuses 5 eingeführten Reinigungsgerätes (beispielsweise eines Staubsaugers mit langem Saugrohr) kann daher das Innere der oberen und unteren Düsenkästen 6, 7 (einschließlich der auf der Ausblasseite dieser Kästen vorgesehenen Düsen) bequem gereinigt werden. Ebenso ist durch die Öffnung 9 des Ventilatorgehäuses 5 der Innenraum des Ventilatorgehäuses sowie der Ventilator 4 zu Reinigungszwecken gut zugänglich.As can be seen in the drawing, the opening 9 provided in the fan housing 5 extends to the upper edge of the housing 5 and thus extends over the entire height range of the inlet openings of the nozzle boxes 6 and 7 of a vacuum cleaner with a long suction tube), the inside of the upper and lower nozzle boxes 6, 7 (including the nozzles provided on the outlet side of these boxes) can therefore be easily cleaned. Likewise, the interior of the fan housing and the fan 4 are easily accessible through the opening 9 of the fan housing 5 for cleaning purposes.

Zum Verständnis sei angemerkt, daß in der Zeichnung die feste Decke des Ventilatorgehäuses 5 weggelassen ist, um die Eintrittsöffnungen der oberen Düsenkästen 6 sichtbar zu machen.For understanding, it should be noted that the fixed ceiling of the fan housing 5 is omitted in the drawing is to make the inlet openings of the upper nozzle boxes 6 visible.

Das Verschlußorgan der Öffnung 9 des Ventilatorgehäuses 5 kann beispielsweise durch einen Deckel gebildet werden, der mittels lösbarer Halterungselemente, beispielsweise durch Spannschrauben, befestigt wird.The closure member of the opening 9 of the fan housing 5 can be formed, for example, by a cover which is fastened by means of detachable mounting elements, for example by means of clamping screws.

Zweckmäßig werden geeignete Sicherungsmaßnahmen getroffen, um zu gewährleisten, daß der die Öffnung 9 des Ventilatorgehäuses 5 verschließende Deckel (nach Öffnen der Türe 11) erst abgenommen werden kann, wenn der Motor 3 abgeschaltet und der Ventilator 4 zum Stillstand gekommen ist.Appropriate security measures are expediently taken to ensure that the cover closing the opening 9 of the fan housing 5 (after opening the door 11) can only be removed when the motor 3 is switched off and the fan 4 has come to a standstill.
