Bezeichnung: Absaughaube, insbesondere fürDesignation: Extraction hood, especially for
HolzbearbeitungsmaschinenWoodworking machines
Die Neuerung betrifft eine Absaughaube, insbesondere für Holzbearbeitungsmaschinen, wobei die Absaughaube ein sich drehendes Werkzeug der Holzbearbeitungsmaschine formschlüssig in geringem Abstand, eine Bearbeitungszone freilassend umgibt und wobei die Absaughaube mit einem Absaug luftkanaI verbunden ist.The innovation relates to an extraction hood, in particular for woodworking machines, whereby the extraction hood surrounds a rotating tool of the woodworking machine in a form-fitting manner at a small distance, leaving a processing zone free and whereby the extraction hood is connected to an extraction air duct.
Bei zerspanungsintensiven Holzbearbeitungsmaschinen, z.B. in der Fensterfertigung, zeigt die Erfahrung, daß vom Werkzeug in der Absaughaube Späne und Stäube in Drehrichtung des Werkzeuges mitgerissen werden, die dann am Austritt des Werkzeuges aus der Absaughaube in die Umgebung gelangen.In the case of woodworking machines that are used for intensive machining, e.g. in window production, experience shows that chips and dust are carried along by the tool in the extraction hood in the direction of rotation of the tool, which then enter the environment when the tool exits the extraction hood.
Da derartige Holzstäube gesundheitsschädlich sind, wird versucht, durch Erhöhung der Absaugleistung eine Verbesserung zu erzielen. Dies führt zu erhöhten Betriebskosten. Außerdem ist oftmals bei Altanlagen eine Erhöhung der Absaugleistung ohne wesentliche Eingriffe in die Holzverarbeitungsmaschine nicht mög lieh.Since such wood dust is harmful to health, attempts are made to improve the situation by increasing the extraction capacity. This leads to increased operating costs. In addition, it is often not possible to increase the extraction capacity of old systems without making significant changes to the wood processing machine.

Die Aufgabe der Neuerung besteht daher darin, eine Absaughaube der eingangs genannten Art derart weiterzubi Lden, daß auf einfache und kostengünstige Weise auch Holzstäube und dgl. sicher abgesaugt werden.The aim of the innovation is therefore to further develop an extraction hood of the type mentioned above in such a way that wood dust and the like can also be safely extracted in a simple and cost-effective manner.
Diese Aufgabe wird dadurch gelöst, daß in Drehrichtung des Werkzeuges nahe am Auslauf des Werkzeuges aus der Absaughaube in die Bearbeitungszone ein zweiter Absaug luftkanaI mit der Absaughaube verbunden ist.This task is solved by connecting a second extraction air duct to the extraction hood in the direction of rotation of the tool, close to the outlet of the tool from the extraction hood into the processing zone.
Vorteilhaft mündet der zweite AbsaugLuftkanaL in einem schmaLen Spalt in die Absaughaube.It is advantageous if the second extraction air duct opens into a narrow gap in the extraction hood.
Vorzugsweise mündet der zweite Absaugluftkanal derart in die Absaughaube, daß die Absaugrichtung in Drehrichtung des Werkzeuges verläuft.Preferably, the second suction air duct opens into the suction hood in such a way that the suction direction runs in the direction of rotation of the tool.
Die Neuerung ist in der Zeichnung beispielhaft dargestellt. Ein sich in Richtung des mit 2 bezeichneten PfeiLes drehendes Werkzeug 1 einer nicht weiter dargestellten Holzbearbeitungsmaschine ist formschlüssig in geringem Abstand von einer Absaughaube 3 umgeben, die eine Bearbeitungszone frei läßt und mit einem AbsaugLuftkanal 5 verbunden ist.The innovation is shown as an example in the drawing. A tool 1 of a woodworking machine (not shown) rotating in the direction of the arrow marked 2 is surrounded in a form-fitting manner at a short distance by an extraction hood 3, which leaves a processing zone free and is connected to an extraction air duct 5.
Wie die Zeichnung weiter zeigt, ist in Drehrichtung 2 des Werkzeuges 1 nahe am Auslauf des Werkzeuges aus der Absaughaube 3 in die Bearbeitungszone 4 ein zweiter AbsaugLuftkanaL 6 angeordnet, der in einem schmalen Spalt 7 in die Absaughaube mündet, wobei in diesem Spalt die Absaugrichtung der durch den AbsaugkanaL 6 saugenden Luft in Drehrichtung 2 des Werkzeuges 1 verläuft.As the drawing further shows, in the direction of rotation 2 of the tool 1, close to the outlet of the tool from the suction hood 3 into the processing zone 4, a second suction air duct 6 is arranged, which opens into the suction hood in a narrow gap 7, whereby in this gap the suction direction of the air sucked through the suction duct 6 runs in the direction of rotation 2 of the tool 1.

Die vom Werkzeug 1 in Drehrichtung zum Auslauf aus der Absaughaube 3 mitgerissenen Partikel werden so dem Spalt 7 zugeführt und wegen der dort herrschenden erhöhten Absauggeschwindigkeit der Luft sicher in den zweiten Absaug luftkana I 6 abgeführt.The particles entrained by the tool 1 in the direction of rotation to the outlet from the suction hood 3 are thus fed to the gap 7 and, due to the increased suction speed of the air prevailing there, are safely discharged into the second suction air channel 6.
Vorzugsweise ist die Breite des Spaltes ca. 10 mm. Bei einer Werkzeughöhe von 450 mm und einem Werkzeugdurchmesser von 300 mm sowie einer Werkzeugdrehzahl von 3000 U/min soll die Spaltbreite ca. 13 mm betragen, um die vom Werkzeug 1 erzeugte Luftgeschwindigkeit von 47 m/sec. zu überwinden. Der Ausgangsrohrdurchmesser des zweiten Absaugluftkanals 6 Liegt dabei bei etwa 120 mm.Preferably, the width of the gap is approximately 10 mm. With a tool height of 450 mm and a tool diameter of 300 mm and a tool speed of 3000 rpm, the gap width should be approximately 13 mm in order to overcome the air speed of 47 m/sec generated by tool 1. The outlet pipe diameter of the second extraction air duct 6 is approximately 120 mm.
