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 i st,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 Bearbeitungszone in die Umgebung gelangen.In the case of woodworking machines that produce a lot of cutting work, e.g. in window production, experience shows that the tool in the extraction hood carries chips and dust in the direction of rotation of the tool, which then enter the environment when the tool exits the extraction hood into the processing zone.
L 229 PA Schönherr/Serw^:*.L 229 PA Schönherr/Serw^:*.
Da derartige Holzstäube gesundheitsschädLich sind, wird versucht, durch Erhöhung der Absaug Leistung 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 weiterzubiLden, 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 extracted safely in a simple and cost-effective manner.
Diese Aufgabe wird dadurch geLöst/. daß in Drehrichtung des Werkzeuges im Abstand vor dem AusLauf des Werkzeuges aus der Absaughaube in die Bearbeitungszone in dem Raum zwischen Werkzeug und Absaughaube eine Lufteinströmdüse derart angeordnet ist, daß die Einströmrichtung der Luft entgegen der Drehrichtung des Werkzeuges verLäuft.This task is solved by arranging an air inlet nozzle in the direction of rotation of the tool at a distance before the tool exits from the extraction hood into the processing zone in the space between the tool and the extraction hood in such a way that the inflow direction of the air runs counter to the direction of rotation of the tool.
VorteiLhaft ist die Einstömdüse mit einem Druck Luftspeieher verbunden.It is advantageous if the inlet nozzle is connected to a pressure air reservoir.
VorteiLhaft ist die Lufteinströmdüse über eine LuftLeitung mit einem VentiLator verbunden.It is advantageous if the air inlet nozzle is connected to a fan via an air line.
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 4 frei Läßt und mit einem Absaug LuftkanaL 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 4 free and is connected to an extraction air duct 5.

Wie die Zeichnung weiter zeigt, ist in Drehrichtung 2 des Werkzeuges 1 im Abstand vor dem AusLauf des Werkzeuges aus der Absaughaube 3 in die Bearbeitungszone 4 in dem Raum zwischen Werkzeug und Absaughaube eine Lufteinströmdüse 6 derart angeordnet, daß die Einströmrichtung der Luft entgegen der Drehrichtung des Werkzeuges verLäuft.As the drawing further shows, in the direction of rotation 2 of the tool 1, at a distance before the tool exits from the extraction hood 3 into the processing zone 4, an air inlet nozzle 6 is arranged in the space between the tool and the extraction hood in such a way that the inflow direction of the air runs counter to the direction of rotation of the tool.
Die vom Werkzeug 1 in Drehrichtung 2 mitgerissenen Partikel werden zunächst an der strömungsoptimierten Absaughaube 3 verzögert und dann durch den von der Lufteinströmdüse 6 erzeugten Luftstrom aufgestaut, so daß sie von der AbsaugLuft des AbsaugkanaLs 5 zur Absaugung erfaßt werden können.The particles carried along by the tool 1 in the direction of rotation 2 are initially delayed at the flow-optimized suction hood 3 and then accumulated by the air flow generated by the air inlet nozzle 6 so that they can be captured by the suction air of the suction channel 5 for suction.
Die Lufteinströmdüse kann dabei über Druckluft oder zweckmäßigerweise über einen Ventilator, der über die Werkzeugspindel angetrieben wird, mit Luft beaufschlagt werden.The air inlet nozzle can be supplied with air using compressed air or, more conveniently, using a fan that is driven by the tool spindle.
Bei einer Werkzeughöhe von 450 mm und einem Werkzeugdurchmesser von 300 mm sowie bei einer Werkzeugdrehzahl von 3000 U/min soll die Düsenabmessung bei einem vorhandenen Luft stromvo lumen von 1000 m3 pro Stunde ca. 450 mm &khgr; 13 mm betragen, um die durch die Werkzeugrotation entstehende maximale Luftgeschwindigkeit von 47 m pro Sekunde sicher aufzustauen.With a tool height of 450 mm and a tool diameter of 300 mm as well as a tool speed of 3000 rpm, the nozzle dimension should be approximately 450 mm x 13 mm for an existing air flow volume of 1000 m 3 per hour in order to safely absorb the maximum air speed of 47 m per second caused by the tool rotation.
