Description
Die Erfindung betrifft einen Rotations-Kantendreher für Webmaschinen, mittels welchem durch eine Dreherbindung die Schußfäden an den Gewebekanten abgebunden werden.The invention relates to a rotary edge turner for weaving machines, by means of which the wefts through a twist tie be tied at the fabric edges.
Bekannt ist aus der DE-OS 24 23 454 eine Anordnung zum
Verfestigen einer Gewebekante durch eine Dreherbindung.
Diese Anordnung gemäß dem Oberbegriff des Anspruchs 1 besteht aus einer drehangetriebenen Dreherscheibe,
deren geometrische Mittenachse parallel zur Schußrichtung
der Webmaschine liegt und wobei die Dreherscheibe mit
gleicher Drehzahl wie der die Dreherspulen tragende Spulenhalter
angetrieben ist.
Die Dreherscheibe weist zwei zu ihrer Mittenachse symmetrisch
angeordnete Schlitze für die Dreherfäden auf.From DE-OS 24 23 454 an arrangement for solidifying a fabric edge by a leno weave is known. This arrangement according to the preamble of
The rotating disc has two slots for the leno threads arranged symmetrically to its central axis.
Der Antrieb des an beiden Seiten der Webmaschine neben den
Randkettfäden angeordneten Kantendrehers erfolgt derart, daß
die den eigentlichen Kantendreher bildende Dreherscheibe über
einen Zahnriemen mit einem Antriebsrad in drehangetriebener
Verbindung steht.
Das Antriebsrad ist mit einer zahnradgetriebenen Vorgelegewelle
drehfest verbunden und von dieser angetrieben. Die Vorgelegewelle
wiederum ist durch einen Zahnriemen mit dem Hauptantrieb
der Webmaschine drehangetrieben verbunden.The drive of the edge turner arranged on both sides of the weaving machine next to the edge warp threads takes place in such a way that the rotary disc forming the actual edge rotator is connected to a drive wheel in a rotationally driven connection via a toothed belt.
The drive wheel is non-rotatably connected to and driven by a gear-driven countershaft. The countershaft is in turn connected to the main drive of the weaving machine by a toothed belt.
Zur Anpassung der bekannten Anordnung an unterschiedliche Webbreiten
ist die Vorgelegewelle mit einer in Richtung Webbreitenverstellung
ragenden Hohlwelle verbunden, in welcher ein
den Antrieb der zweiten Dreherscheibe und den Antrieb des
zweiten Dreherspulenhalters bewerkstelligendes Wellenteil
verschiebbar ist.
Ein derartiger Antrieb ist kostenaufwendig, nicht raumsparend,
nicht unabhängig vom Hauptantrieb der Webmaschine und
nicht individuell ansteuerbar.To adapt the known arrangement to different weaving widths, the countershaft is connected to a hollow shaft protruding in the direction of the weaving width adjustment, in which a shaft part which drives the second rotator disk and the drive of the second rotator bobbin holder can be displaced.
Such a drive is expensive, not space-saving, not independent of the main drive of the weaving machine and cannot be controlled individually.
Ferner ist aus der DE-OS 28 32 131 eine sogenannte Satellitendrehereinrichtung
zur Bildung von Gewebekanten auf schützenlosen
Webmaschinen bekannt. Die Dreherscheibe besitzt eine Außenverzahnung.
Des weiteren ist die Dreherscheibe lünettartig
drehend gelagert.
Von einem Spulendreher, der drehangetrieben mit der Dreherscheibe
in Wirkverbindung steht, werden die Dreherfäden abgezogen
und einer zentrisch in der Dreherscheibe gelegenen Führungsöffnung
zugeführt.
Die Dreherscheibe besitzt ferner zwei einander diametral
gegenüberliegend in der Dreherscheibe angeordnete Osen,
durch welche der Faden hindurch zum Bindepunkt des Gewebes
geführt ist.
Die Außenverzahnung der Dreherscheibe steht hier mit den
Zähnen eines Antriebszahnrades in Eingriff, das den Dreherspulenhalter
synchron mit der Dreherscheibe antreibt.
Über die Art der Antriebsquelle der Drehereinrichtung ist aus
dieser vorbekannten Schrift kein Hinweis zu entnehmen. Es kann
aber davon ausgegangen werden, daß der Antrieb, wie allgemein
bekannt, vom Hauptantrieb der Webmaschine abgeleitet ist.
Damit ist auch diese Antriebslösung kostenaufwendig, weil diese
nicht ohne weiteres an unterschiedliche Webbreiten der Maschine
anpaßbar ist.
Eine derartige Drehereinrichtung ist auch mit erheblichen
Nachteilen für den Hersteller und den Betreiber der Webmaschine
verbunden.
So ist ein relativ großer Platzbedarf rechts und links der
Webkette zur Einordnung der Vorrichtung in die Webmaschine
erforderlich.
Eine derartige Drehervorrichtung ist in der Regel im Bereich
des Hinterfaches angeordnet. Dies aber bedeutet, daß damit
die Anzahl der einsetzbaren Webschäfte eingeschränkt ist und
die Länge der Dreherfäden, gemessen von der Drehervorrichtung
bis zum Punkt der Abbindung des Schußfadens, relativ groß ist.
Diese Länge verursacht ein sehr flach ausgebildetes Dreherfaden-Fach.
Eine derart flache Fachausbildung gewährleistet
aber nicht immer, daß jeder Schußfaden ordnungsgemäß in das
Dreherfaden-Fach gelangt.Also known from DE-OS 28 32 131 is a so-called satellite turning device for forming fabric edges on defenseless weaving machines. The rotating disc has external teeth. Furthermore, the rotating disc is rotatably mounted in a bezel-like manner.
The leno threads are drawn off from a bobbin winder, which is rotationally driven and operatively connected to the rotating disc, and fed to a guide opening located centrally in the rotating disc.
The rotating disc also has two diametrically opposed loops arranged in the rotating disc, through which the thread is guided to the weaving point of the fabric.
The external toothing of the rotating disc is in engagement with the teeth of a drive gear which drives the rotating coil holder in synchronism with the rotating disc. No information can be found from this previously known document about the type of drive source of the turning device. However, it can be assumed that the drive, as is generally known, is derived from the main drive of the weaving machine.
This drive solution is therefore also expensive because it cannot be easily adapted to different weaving widths of the machine.
Such a lathe device is also associated with considerable disadvantages for the manufacturer and the operator of the weaving machine.
A relatively large amount of space is required on the right and left of the weaving chain to classify the device in the weaving machine.
Such a lathe device is usually arranged in the area of the rear compartment. However, this means that the number of usable heald frames is limited and the length of the leno threads, measured from the leno device to the point at which the weft thread is tied, is relatively large. This length creates a very flat leno thread compartment. Such a flat technical training does not always ensure that every weft thread gets properly into the leno thread compartment.
Vor diesem Hintergrund ist es daher Aufgabe der Erfindung, einen, unter Vermeidung der Nachteile des Standes der Technik, individuell ansteuerbaren und damit unabhängig vom Webmaschinenantrieb antreibbaren Rotations-Kantendreher zu schaffen, mit welchem zu beiden Seiten des Gewebes die einzelnen Schußfäden fest abgebunden werden können und eine qualitätsgerechte und dauerhafte Gewebekante herstellbar ist.Against this background, it is therefore an object of the invention one while avoiding the disadvantages of the prior art, individually controllable and therefore independent of the weaving machine drive to create drivable rotary edge rotators with which on each side of the fabric the individual Weft threads can be tied firmly and a quality-appropriate and permanent fabric edge can be produced.
Der Kantendreher soll, im Gegensatz zum Stand der Technik, zum Zwecke des Artikelswechsels nicht von der Webmaschine getrennt werden und der Kantendreher soll ohne weiteres an unterschiedliche Webbreiten anpaßbar sein. Damit soll eine erhebliche Einsparung an Rüstzeit in den Webereien erreicht werden.In contrast to the prior art, the edge turner should Not separated from the weaving machine for the purpose of changing articles and the edge turner should easily be sent to different Web widths are customizable. This is said to be significant Saving of makeready times can be achieved in the weaving mills.
Der Rotations-Kantendreher soll ferner einen einfachen konstruktiven Aufbau besitzen und direkt, d.h. ohne der Einbeziehung eines Übertragungsmittels zwischen dem Stellmotor und der Dreherscheibe, antreibbar sein. The rotary edge turner should also be a simple constructive Own structure and direct, i.e. without inclusion a transmission medium between the servomotor and the Rotary disc, be drivable.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des
Anspruchs 1 gelöst.
Mit dem elektromotorischen Stellantrieb wird es nun erstmals
möglich, den Bewegungsablauf der einzelnen Kantendreher
unabhängig voneinander und unabhängig von den Webmaschinenantrieb
zu steuern.
So ist es zum Beispiel denkbar, daß die Abbindung der
Schußfäden in Abhängigkeit vom Typ des Schußfadens erfolgen
kann und daß die Abbindung des Schußfadens auf der Seite des
Schußfadeneintrags zeitlich vor der Abbindung des Schußfadens
auf der Schußfadenankunftseite liegen kann.According to the invention the object is achieved by the features of
With the electromotive actuator it is now possible for the first time to control the sequence of movements of the individual edge twists independently of one another and independently of the weaving machine drive.
It is conceivable, for example, that the setting of the weft threads can take place depending on the type of the weft thread and that the setting of the weft thread on the side of the weft thread insertion can be before the setting of the weft thread on the weft thread arrival side.
Durch die individuelle Ansteuerung sind z. B. Bordüren und
Schußverdichtungen mit unterschiedlichen Bindungen ohne zusätzlichen
Vorrichtungsaufwand herstellbar.
So sind Einfachbindungen und Bindungsaussetzer allein durch
entsprechende Ansteuerung des Stellantriebes des jeweiligen
Rotations-Kantendrehers erreichbar.Due to the individual control z. B. Borders and weft compression with different bindings can be produced without additional device effort.
Single bindings and binding misfires can only be achieved by appropriate control of the actuator of the respective rotary edge rotator.
Durch eine gesteuerte Drehrichtungsumkehr der Dreherscheibe, worunter letztlich auch eine oszillierende Drehrichtungsumkehr zu verstehen ist, kann auf den Antrieb des Dreherspulenhalters verzichtet werden, weil in jedem Falle die Verdrehungen oder Umschlingungen der Dreherfäden auf dem Wege zwischen den Dreherspulen und der Dreherscheibe, hervorgerufen durch eine bestimmte Anzahl von Rechtsdrehungen der Dreherscheibe, durch die gleiche Anzahl von Linksdrehungen der selben Dreherscheibe, wieder aufgehoben werden.Through a controlled reversal of the direction of rotation of the rotating disc, ultimately including an oscillating reversal of the direction of rotation can be understood, can be on the drive of the rotary coil holder to be dispensed with, because in any case the twists or Wrapping of the leno threads on the way between the leno bobbins and the rotating disc, caused by a certain number of right turns of the rotating disc, by the same number of left turns of the same rotating disc, be canceled again.
Mit dem stellmotorgetriebenen Rotations-Kantendreher ist es ferner ohne weiteres möglich, innerhalb der Webmaschinensteuerung einen Drehzahlabgleich zwischen der Fachbildeeinrichtung und der Drehzahl der Dreherscheibe des Rotations-Kantendrehers derart herbei zu führen, daß der Bewegungsablauf der Fachbildeorgane zur Ausbildung der Webfachgeometrie nahezu kongruent ist mit dem Bewegungsablauf des Rotations-Kantendrehers zur Ausbildung der Geometrie des Dreherfachs. It is with the servomotor-driven rotary edge driver also easily possible within the weaving machine control a speed comparison between the shedding device and the speed of rotation of the rotary edge rotator to bring about in such a way that the movement of the Specialist organs for the formation of the shed geometry almost is congruent with the sequence of movements of the rotary edge rotator to form the geometry of the lathe compartment.
Damit ist sichergestellt, daß die Schußfäden auch ordnungsgemäß das Dreherfach links- und rechtsseitig der Kettfäden passieren bzw. in dieses eingetragen werden.This ensures that the weft threads are also correct pass the leno pocket on the left and right side of the warp threads or be entered in this.
Vorteilhafterweise kann dieser Kantendreher in einen möglichst
geringen Abstand zum Bindepunkt des Gewebes und zwischen den
Schaftrahmen und den Weblitzen der ersten Webschäfte positioniert
sein.
Damit ist die Anzahl einsetzbarer Webschäfte in Richtung
Kettbaum, d.h. der Webrichtung entgegengesetzt, nicht begrenzt.This edge turner can advantageously be positioned as close as possible to the weaving point of the fabric and between the frame and the healds of the first heald frames.
The number of usable heald frames in the direction of the warp beam, ie opposite to the weaving direction, is thus not limited.
Durch die kompakte Ausführung des Kantendrehers ist im Falle eines Artikelwechsels oder einer Webbreitenverstellung ein schnelles Postionieren des Kantendrehers an die geänderten Bedingungen der Webmaschine möglich.Due to the compact design of the edge turner is in the case an article change or a web width adjustment rapid positioning of the edge turner to the changed ones Weaving machine conditions possible.
Im Vergleich mit einem herkömmlichen Satellitendreher, der in Webrichtung gesehen vor den Webschäften angeordnet ist, wird mit der Anordnung des erfindungsgemäßen Rotations-Kantendrehers innerhalb der Webschäfte, die dem Webblatt am nächsten angeordnet sind, deutlich, daß der Hub der Dreherfäden bei Anwendung eines Rotations-Kantendrehers nur etwa 80 mm beträgt während die Dreherfäden bei einem Satellitendreher einen Hub von etwa 180 mm ausführen müssen, um eine ausreichende Fachöffnung zu erzielen.Compared to a conventional satellite driver that works in Weaving direction is arranged in front of the heald frames with the arrangement of the rotary edge driver according to the invention within the heald frames that are closest to the reed are clear that the stroke of the leno threads when used a rotary edge turner is only about 80 mm during the leno threads in a satellite lathe have a stroke of about 180 mm must be carried out in order to have a sufficient compartment opening achieve.
Ein weiterer Vorteil der Erfindung besteht darin, daß zusätzliche, den Antrieb der Dreherscheibe bewirkende Mittel, wie z.B. ein mit dem Stellmotor verbundenes Antriebszahnrad und ein den Motordrehantrieb auf die Dreherscheibe übertragenden Zahnriemen, zwischen dem Stellmotor und der Dreherscheibe entfallen.Another advantage of the invention is that additional, means causing the rotation of the rotating disc, e.g. a drive gear connected to the actuator and a Motor rotary drive on toothed belt that transmits the rotating disc, between the servomotor and the rotator disc.
