Description

Trommelschwingmaschine Die Erfindung bezieht sich auf eine Trommelschwingmaschine mit zwei gegenläufigen Trommeln und einer die Fasern während des Schwingens lenkenden Elasv orrichtung.Vibrating drum machine The invention relates to a vibrating drum machine with two counter-rotating drums and one that directs the fibers while swinging Elas device.

Bei der bekannten Schwingmaschine besteht die Blasvorrichtuns aus Ventilatoren, die auf den Schwing trommelachsen befestigt sind. Diese Ausbildung der Blasvorrichtung hat zur Voraussetzung, daß die Schwingtrommeln selbst durchbrochen sind; denn sonst könnte der von den Ventilatoren erzeugte Blasstrom nicht vom Innern der Schw ingtrommeln nach außen gelangen. Die Anwendung der bekannten Blasvorrichtung ist demgemäß auch nur eine beschränkte. Sie ist z. B. dann nicht anwendbar, wenn die Schwingtrommeln geschlossen sind. Im übrigen ist der Zweck der Ventilatoren bei der bekannten Schwingmaschine in erster Linie die Herausführung der beim Schwingprozeß anfallenden Holzteile, der sogenannten Scheben.In the known vibrating machine, the blower consists of Fans that are attached to the swing drum axles. This training The prerequisite for the blower is that the vibrating drums break through themselves are; otherwise the blowing current generated by the fans would not be able to come from inside the vibrating drums get to the outside. The application of the known blowing device is accordingly only a limited one. She is z. B. not applicable if the vibrating drums are closed. Otherwise is the purpose of the fans in the known vibrating machine primarily the removal of the vibrating process accruing wooden parts, the so-called Scheben.

Nach der Erfindung besteht demgegenüber die Blasvorrichtung aus außen längs den Trommeln verlaufenden Schlitzdüsen, deren Blasströme aufeinander zu gerichtet sind. Diese Ausbildung der Blasvorrichtung gibt die Möglichkeit, die Blasvorrichtung auch bei geschlossenen Schwingtrommeln zum Verhindern des Aufwickelns anzuwenden.According to the invention, on the other hand, the blowing device consists of the outside slot nozzles running along the drums, the blow streams of which are directed towards one another are. This design of the blower gives the possibility of the blower Can also be used with closed vibrating drums to prevent unwinding.

Auf der Zeichnung ist eine Ausführungsform der Erfindung als Beispiel. dargestellt. Fig. i zeigt die Erfindung in schaubildlicher Darstellung. Fig. 2 ist in kleinerem Maßstabe ein Querschnitt durch das Trommelpaar.The drawing shows an embodiment of the invention as an example. shown. Fig. I shows the invention in a diagrammatic representation. Fig. 2 is on a smaller scale, a cross-section through the pair of drums.

Auf Längswellen i, i' sind Schwingtrommeln 2, 2' befestigt. Die Wellen der Schwingtrommeln sind in Lagern 3, 4 bzw. 3', 4' drehbar. Die Wellen i, i' drehen sich im Sinne der eingezeichneten Pfeile gegenläufig. Der Antrieb erfolgt von dem Zahnrad 5 aus über die Räder 6, 7. Die Trommeln 2, 2' bestehen aus länglichen, gerundeten Blechstücken, die mit dem Bogen nach innen weisend zusammengeschweißt sind. Die Kanten, mit denen zwei Ausrundungen zusammengeschweißt sind, bilden die Schwingmesser.Vibrating drums 2, 2 'are attached to longitudinal shafts i, i'. The waves the vibrating drums can be rotated in bearings 3, 4 or 3 ', 4'. The shafts i, i 'turn in opposite directions in the sense of the arrows drawn. The drive takes place from the Gear 5 from over the wheels 6, 7. The drums 2, 2 'consist of elongated, rounded Pieces of sheet metal that are welded together with the arch pointing inwards. the Edges with which two fillets are welded together form the oscillating knife.

Außen neben den Trommeln 2, 2' sind Schlitzdüsen 8, 8' angeordnet. Diese Schlitzdüsen sind so verlegt, daß die von ihnen erzeugten Blasströme nach der Maschinenmitte zu gerichtet sind. Wie aus Fig.2 ersichtlich ist, blasen sie die Fasern, die im Begriff sind, sich an die Trommel anzulegen, von den Trommeln weg, so daß ein Wickeln der Fasern um die Trommeln herum nicht stattfinden kann.Slotted nozzles 8, 8 'are arranged on the outside next to the drums 2, 2'. These slot nozzles are laid in such a way that the blow streams generated by them follow are directed towards the center of the machine. As can be seen from Fig.2, they blow the fibers about to lay against the drum from the drums away, so that winding of the fibers around the drums cannot take place.
