Description
Doppelriemchenstreckwerk, insbesondere für lange Fasern Die Erfindung betrifft ein Doppelriemchenstreckwerk, insbesondere für lange Fasern, mit einer sich über den gesamten Druckbereich erstreckenden Führung für das Unterriemchen und mehreren mit regelbarem Federdruck belasteten Druckgliedern für das faserführende Trum des Oberriemchens.Double apron drafting system, especially for long fibers The invention relates to a Doppelriemchenstreckwerk, especially for long fibers, with a guide for the lower apron extending over the entire printing area and several pressure members loaded with adjustable spring pressure for the fiber guide Trum of the upper apron.
Es ist bekannt, bei Doppelriemchenstreckwerken im Innern beider Riemchenschleifen je eine Führung in Form einer Blattfeder vorzusehen, welche sich über dem gesamten Druckbereich der Riemchen zwischen den Führungswalzen und den Wendegliedern erstreckt. Ganz abgesehen davon, daß eine Regelbarkeit des Anlegedruckes der Federbügel auf der ganzen wirksamen Riemchenlänge nicht vorgesehen ist, so daß ein Anpassen des Streckwerkes an verschiedene Arbeitsbedingungen nicht möglich ist, nimmt bei einer derartigen Belastung durch eine Bügelfeder die Federkraft vom Befestigungspunkt der Feder bis zur Federspitze ab, so daß dementsprechend der von der Feder auf das Riemchentrum ausgeübte Druck sich nach dem Ende zu verringert.It is known to have double apron stretchers inside both apron loops to provide a guide in the form of a leaf spring, which extends over the entire Extends pressure area of the aprons between the guide rollers and the turning members. Quite apart from the fact that the contact pressure of the spring clip can be regulated the entire effective strap length is not provided, so that an adjustment of the Drafting system is not possible at different working conditions, takes one such a load by a bow spring, the spring force from the attachment point the nib down to the tip of the nib, so that accordingly the from the nib on the The pressure exerted on the belt center decreases after the end.
Gegenstand eines älteren Rechtes ist ein Doppelriemchenstreckwerk für Bast- oder lange Blattfasern, bei dem innerhalb der Oberriemchenschleife ein um eine Achse schwenkbarer Tragrahmen mit einer Anzahl flacher Andrückplatten gelagert ist, die in ihrer Gesamtheit unter Federwirkung stehen und mit ihren bis nahe an die Wendewalze für das Oberriemchen herangeführten Enden in einer Linie gegenüber dem Klemmpunkt des Streckwerkes der Doppelriemchen gegen das wirksame Trum des Oberriemchens zur Anlage kommen.The subject of an earlier right is a double-belt stretching system for bast or long leaf fibers, with one inside the top apron loop Support frame pivotable about an axis is mounted with a number of flat pressure plates is, which are in their entirety under spring action and with their up close to the turning roller for the upper apron brought up ends in a line opposite the clamping point of the drafting system of the double apron against the effective strand of the upper apron come to the plant.
Die hiermit erzielbare Belastung des wirksamen Trums des Oberriemchens erfolgt somit nur in einer Linie, innerhalb der die einzelnen Platten mit ihren Enden zur Auflage auf das Trum kommen. Es ist hiermit nicht möglich, eine über die ganze Länge des wirksamen Riemchentrums verteilte Belastung herbeizuführen. Auch sind die einzelnen Belastungsplatten nicht unabhängig voneinander regelbar belastbar.The load that can be achieved in this way on the effective run of the upper apron thus takes place only in one line, within which the individual plates with their The ends come to rest on the strand. It is not possible to use the to bring about a distributed load over the entire length of the effective belt center. Even the individual loading plates cannot be loaded independently of each other.
Diesem Mangel wird gemäß der Erfindung dadurch begegnet, daß zwischen der Riemchenoberwalze und dem Riemchenwendeglied mehrere Druckwälzchen angeordnet sind, die auf das faserführende Trum des Oberriemchens an mehreren in der Laufrichtung dieses Trums hintereinanderliegenden Stellen senkrecht zur Streckfeldebene einen Druck ausüben.This deficiency is countered according to the invention in that between the apron top roller and the apron turning member arranged a plurality of pressure rollers that are on the fiber strand of the upper apron at several in the running direction this run one behind the other places perpendicular to the stretching field plane Exert pressure.
Als besonders vorteilhaft hat es sich im Interesse einer Verringerung der Abnutzung zusammenarbeitender Teile erwiesen, wenn die Druckwälzchen mit einem elastischen Überzug versehen sind. Solche Walzenüberzüge sind wohl für die Streckwerkswalzen an sich bekannt, sie haben dort jedoch den Zweck, die Berührungsfläche zwischen Druckwalze und Unterzylinder möglichst zu vergrößern, um die Klemmwirkung zwischen beiden bei geringstem Druck möglichst groß zu halten. Zur Belastung eines Riemchens bei Riemchenstreckwerken haben solche Walzen jedoch bisher keine Verwendung gefunden.It has proven to be particularly advantageous in the interest of a reduction the wear of cooperating parts when the pressure rollers with a elastic cover are provided. Such roll covers are probably for the drafting rolls known per se, but there they have the purpose of the interface between To enlarge the pressure roller and lower cylinder as possible in order to maintain the clamping effect between to keep both as large as possible with the lowest pressure. To load a strap however, such rollers have so far not been used in apron drafting units.
Eine besonders einfache Bauart ergibt sich, wenn die Belastungsfedern für die Druckwälzchen in bekannter Weise in dem hochschwenkbaren Tragarm untergebracht sind.A particularly simple design results when the loading springs housed for the pressure roller in a known manner in the pivoting arm are.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch wiedergegeben und wird in folgendem beschrieben: Das Unterriemchen 1 ist in bekannter Weise um eine Unterriemchenwalze 2, eine Umlenkschiene 3 und eine Spannrolle 4 herumgeführt. Zur Unterstützung des Unterriemchens dient eine bekannte Riemchenbrücke 5. Das Oberriemchen 10 ist in geläufiger Weise um eine Druckwalze 6 und eine belastete Umlenkschiene 7 herumgeführt.An embodiment of the invention is shown schematically in the drawing and is described in the following: The lower apron 1 is guided around a lower apron roller 2, a deflection rail 3 and a tensioning roller 4 in a known manner. A known apron bridge 5 serves to support the lower apron. The upper apron 10 is routed around a pressure roller 6 and a loaded deflection rail 7 in a familiar manner.
In dem freien Raum zwischen Druckwalze und Umlenkschiene 7 befinden sich erfindungsgemäß innerhalb des Oberriemchens ein oder mehrere durch Federn 11 belastete Druckwälzchen B.Located in the free space between the pressure roller and the deflection rail 7 According to the invention, one or more springs 11 within the upper apron loaded pressure rollers B.
Der Federdruck auf die einzelnen Wälzchen 8 kann dabei so eingeregelt werden, daß zwischen den Druckstellen ein Durchzug der Fasern möglich ist. Dies ist besonders für lange Fasern wichtig. Durch Ausrüsten der Druckwälzchen 8 mit einem elastischen Überzug wird die nachgiebig elastische Führung der Fasern zwischen den Riemchen noch verbessert. Die regelbaren Belastungsfedern 11 für die Druckwälzchen 8 sind in bekannter Weise im Oberwalzentragarm 12 untergebracht.The spring pressure on the individual rollers 8 can be adjusted in this way that a passage of the fibers is possible between the pressure points. this is especially important for long fibers. By equipping the pressure roller 8 with an elastic cover is the resiliently elastic guide of the fibers between the straps improved. The adjustable loading springs 11 for the pressure rollers 8 are housed in the upper roll support arm 12 in a known manner.
