Description

Die Erfindung betrifft eine Aufspulmaschine gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a winding machine according to the preamble of claim 1.

Zum Aufspulen bei extrem hohen Fadengeschwindigkeiten - z.B. 6000 m pro Minute - sind Aufspulmaschinen bekannt, bei denen der Faden durch Mitnehmer hin und her geführt wird, die auf zwei gegensinnig bewegten, nebeneinander angeordneten Band- oder Riementrumen befestigt sind. Die alternierende Bewegung des Fadens wird dabei nicht wie bei herkömmlichen Changiereinrichtungen durch einen einzigen, hin und her bewegten Fadenführer bewirkt, sondern dadurch, dass die gegenläufig bewegten Mitnehmer abwechselnd den Faden erfassen und führen. Da die Mitnehmer an den Umkehrpunkten des Fadens weder beschleunigt noch verzögert werden, wird der Einfluss der trägen Masse der Fadenführungsorgane bei der Fadenumkehr völlig ausgeschaltet.For winding at extremely high thread speeds - e.g. 6000 m per minute - winding machines are known in which the thread is guided back and forth by drivers which are fastened on two belt or belt spaces which are arranged in opposite directions and are arranged side by side. The alternating movement of the thread is not caused by a single thread guide moved back and forth, as in conventional traversing devices, but by the fact that the oppositely moving drivers alternately grasp and guide the thread. Since the drivers at the reversal points of the thread are neither accelerated nor decelerated, the influence of the inert mass of the thread guide members is completely eliminated when the thread is reversed.

Durch geeignete Formgebung des Mitnehmers oder durch die relative Anordnung der Riementrume erreicht man, dass der Faden von dem einen Mitnehmer freigegeben und gleichzeitig von dem anderen Mitnehmer übernommen wird. Daher liegen die Umkehrpunkte an den Stellen, an denen sich die Mitnehmer begegnen. Wenn man einen Spulenaufbau mit ebenen, exakten Endflächen erreichen will, müssen die Umkehrpunkte stets exakt an den gleichen Stellen liegen. Unregelmässige Abweichungen, selbst wenn sie in der Grössenordnung der Dicke eines Fadens liegen, verursachen einen unsauberen Kantenaufbau. Es treten sogenannte Querschläger auf, das heisst kurze Fadenstücke, die sehnenförmig über den Rand der Wicklung laufen. Daher ist es notwendig, die Bewegung der Mitnehmer sorgfältig zu synchronisieren.By suitable shaping of the carrier or by the relative arrangement of the belt spaces, one achieves that the thread is released by one carrier and at the same time taken over by the other carrier. Therefore, the reversal points are where the drivers meet. If you want to achieve a coil structure with flat, exact end faces, the reversal points must always be in exactly the same places. Irregular deviations, even if they are on the order of the thickness of a thread, cause an unclean edge build-up. So-called ricochets occur, i.e. short pieces of thread that run in a sinew shape over the edge of the winding. It is therefore necessary to carefully synchronize the movement of the drivers.

Die meisten bisher bekannt gewordenen Aufspulmaschinen sind mit zwei umlaufenden Riemen oder Bändern bestückt, auf denen die Mitnehmer sitzen. Die Bänder sind so angeordnet, dass ein Trum des einen Bandes einem in entgegengesetzter Richtung bewegten Trum des anderen Bandeseng benachbartist. Bei diesen Maschinen sind die erwähnten Synchronisationsprobleme besonders ausgeprägt, zum Teil bedingt durch unterschiedliche Dehnungen der Riemen oder Bänder infolge unterschiedlicher Materialeigenschaften oder unterschiedlicher Alterung.Most of the winding machines known to date are equipped with two rotating belts or belts on which the drivers sit. The bands are arranged so that one strand of one band is adjacent to a strand of the other band moving in the opposite direction. The synchronization problems mentioned are particularly pronounced in these machines, in part due to different stretching of the belts or belts as a result of different material properties or different aging.

Es sind auch schon Aufspulmaschinen bekannt, die nur ein einziges umlaufendes Organ aufweisen, dessen gegenläufige Trume durch Umlenkrollen eng nebeneinander geführt sind. Obwohl dabei die materialbedingten Ungenauigkeiten weitgehend ausgeschaltet sind, lassen sich Querschläger nicht ganz vermeiden.Winding-up machines are also known which have only a single revolving organ, the opposite runs of which are guided closely next to one another by deflection rollers. Although the material-related inaccuracies are largely eliminated, ricochets cannot be avoided entirely.

Man hat schon an den Enden des Changierbereichs feststehende Abweiser angeordnet, die den Faden immer exakt an der gleichen Stelle von dem ankommenden Mitnehmer lösen sollen.Fixed deflectors have already been arranged at the ends of the traversing area, which should always detach the thread from the arriving driver at exactly the same point.

Da die bisher erwähnten Massnahmen, die alle schon aus der DE-OS 1535091 bekannt sind, noch nicht immer zum Erfolg führen, hat man die Abweiser verschieblich angeordnet, so dass der Changierhub während des Wickelvorganges mit zunehmendem Wickeldurchmesser verkürzt wird. Der Soll-Umkehrpunkt wandert also von Wickellagezu Wickellage weiter nach innen. Selbst wenn der tatsächliche Umkehrpunkt einer Wickellage - bedingt durch irgendwelche Störeinflüsse - ein wenig jenseits des Soll-Umkehrpunktes liegt, so rutscht der Faden trotzdem nichtvon der Kante ab, da die darunterliegende Lage etwas breiter ist. Die Wickel erhalten daher konische oder gewölbte Endflächen. Bei genügend grossen Konuswinkel lässt sich auf diese Weise das Auftreten von Querschlägern unterdrücken.Since the measures mentioned so far, all of which are already known from DE-OS 1535091, do not always lead to success, the deflectors have been arranged displaceably, so that the traversing stroke is shortened with increasing winding diameter during the winding process. The target reversal point therefore moves further from winding layer to winding layer inwards. Even if the actual reversal point of a winding layer - due to any interference - is a little beyond the target reversal point, the thread does not slip off the edge, since the layer underneath is slightly wider. The wraps therefore have conical or curved end faces. If the cone angle is large enough, the occurrence of ricochets can be suppressed in this way.

Bei der Aufspulmaschine gemäss DE-OS 2622243, von der die Erfindung ausgeht, ist die Verschiebung der Abweiser durch ein Getriebe mit der Position eines Tastorgans gekoppelt, das gegen die Umfangsfläche des Wickels anliegt und entsprechend dem zunehmenden Wickeldurchmesser ausweicht. Von dem Getriebe ist nur ein . sperriges, greiferartiges Gestänge dargestellt, das über eine nicht näher beschriebene Hebeleinrichtung betätigt werden soll. Die genaue Wirkungsweise ist der Druckschrift nicht zu entnehmen, und es ist nicht erkennbar, ob diese Einrichtung für Aufspulmaschinen geeignet ist, bei denen auf einem einzigen Wickeldorn mehrere Wickelstellen in Reihe nebeneinander angeordnet sind. Dieser letztere Gesichtspunkt ist besonders wichtig. Denn gerade beim Aufspulen dünner Fäden mit extrem hohen Geschwindigkeiten hat es sich zwecks Vermeidung übermässiger Wickelgewichte durchgesetzt, auf einem Wickeldorn bis zu acht Wickel unterzubringen.In the winding machine according to DE-OS 2622243, from which the invention is based, the deflection of the deflectors is coupled by a gear to the position of a sensing element, which bears against the circumferential surface of the winding and evades in accordance with the increasing winding diameter. There is only one of the gears. bulky, gripper-like linkage shown, which is to be operated via a lever device not described in detail. The exact mode of action is not apparent from the document, and it is not clear whether this device is suitable for winding machines in which a plurality of winding stations are arranged side by side on a single winding mandrel. This latter point of view is particularly important. Because, especially when winding thin threads at extremely high speeds, it has been established to accommodate up to eight windings on one winding mandrel in order to avoid excessive winding weights.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Aufspulmaschine der im Oberbegriff des Patentanspruchs angegebenen Gattung zu schaffen, diesich durch eine einfache und exakte Steuerung des Changierhubes in Abhängigkeit vom wachsenden Spulendurchmesser auszeichnet, zum gleichzeitigen Aufspulen mehrerer nebeneinanderliegender Wickel geeignet ist und leicht auf eine andere Anzahl von Wickelstellen umstellbar ist.The present invention has for its object to provide a winding machine of the type specified in the preamble of the claim, which is characterized by a simple and exact control of the traversing stroke depending on the growing bobbin diameter, is suitable for simultaneous winding of several adjacent reels and easily to a different number is convertible from winding stations.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Bei dem im Kennzeichen des Anspruchs 1 angegebenen Keil- oder Kurvengetriebe ist die Führungsschiene eine Erzeugende der Endfläche der Spule. Ein wesentlicher Vorteil besteht daher darin, dass man aus der Form und Lage der Führungsschiene unmittelbar anschaulich auf die Form der Endfläche schliessen kann.In the wedge or cam mechanism specified in the characterizing part of claim 1, the guide rail is a generatrix of the end face of the coil. A major advantage is therefore that the shape and position of the guide rail can be used to draw conclusions about the shape of the end face.

Es besteht die Möglichkeit, beide Abweiser einer Wickelstelle je mit dem in Anspruch 1 angegebenen Getriebe separat und unabhängig voneinander zu steuern. Bevorzugt wird aber die in Anspruch 2 angegebene und in Anspruch 3 konkretisierte Variante, bei der durch die Auswahl einer einzigen Führungsschiene eine exakt spiegelemmetrische Wickelform erreicht wird.It is possible to control both deflectors of a winding station separately and independently of one another with the transmission specified in claim 1. However, the variant specified in claim 2 and specified in claim 3 is preferred, in which an exactly mirror-symmetrical winding shape is achieved by the selection of a single guide rail.

Gemäss Anspruch 4 werden bei Aufspulmaschinen mit mehreren nebeneinanderliegenden Wikkelstellen die einander entsprechenden Abweiser aller Wickelstellen mit einem einzigen Getriebe synchron bewegt. Hierbei spielt es keine Rolle, ob die einzelnen Wickelstellen separate Changierbänder haben oder ob sich die Changierbandtrume durchgehend über mehrere Wickelstellen erstrecken.According to claim 4, in the case of winding machines with a plurality of winding points lying next to one another, the mutually corresponding deflectors of all winding points are provided with a single gear moved synchronously. It does not matter whether the individual winding stations have separate traversing belts or whether the traversing belt runs continuously across several winding stations.

Bei einer bevorzugten Ausführungsform, auf die sich der Anspruch 5 bezieht, erstrecken sich die Trume allerdings über die Gesamtlänge der Wikkelstellen. Die Leisten mit den Abweisern haben den Vorteil, dass sie zwecks Umstellung auf eine andere Anzahl von Wickelstellen leicht austauschbar sind. Sie erfüllen zusätzlich die Aufgabe, die eng nebeneinanderliegenden Trume zu führen und getrennt zu halten.In a preferred embodiment, to which claim 5 relates, the dreams, however, extend over the entire length of the winding points. The strips with the bumpers have the advantage that they are easily interchangeable for changing to a different number of winding stations. They also fulfill the task of guiding the closely spaced dreams and keeping them separate.

Die Trennung der beiden Trume ist besonders wichtig, wenn die Trume gemäss Anspruch 6 die Trume eines einzigen Zahnriemens sind und die Verzahnungen einander zugekehrt und eng benachbart sind.The separation of the two strands is particularly important if the strands are the strands of a single toothed belt and the teeth face each other and are closely adjacent.

Eine besonders einfache Bauart ist in Anspruch 7 angegeben.A particularly simple design is specified in claim 7.

Die Ansprüche 8 und 9 betreffen zweckmässige, variable Ausbildungen der Führungsschiene.Claims 8 and 9 relate to expedient, variable designs of the guide rail.

Das Merkmal des Anspruchs 10 sichert Spielfreiheit und damit exakte Bewegungen der Schubstange.The feature of claim 10 ensures freedom from play and thus exact movements of the push rod.

Das Merkmal des Anspruchs 11 trägt zur Minderung von Reibung und Verschleiss bei.The feature of claim 11 contributes to the reduction of friction and wear.

In Figur ist eine Hülse 1 mit Wickel 2 auf einem Wickeldorn 3 zu erkennen. Wie sich weiter unten ergeben wird, hat allerdings die Aufspulmaschine insgesamt vier in Reihe nebeneinanderliegende Wickelstellen, das heisst auf dem Dorn 3 sitzen insgesamt vier Hülsen mit vier Wickeln. Der Wikkeldorn 3 ist mit einem nicht dargestellten Maschinengestell so verbunden, dass sich während des Aufbaus der Wickel 2 seine Lage relativ zum Maschinengestell nicht ändert. Er kann z.B. auf einem Revolverkopf sitzen.A sleeve 1 with a winding 2 on a winding mandrel 3 can be seen in the figure. As will be seen further below, however, the winding machine has a total of four winding positions lying next to one another, that is to say a total of four sleeves with four windings are seated on the mandrel 3. The wedge mandrel 3 is connected to a machine frame (not shown) in such a way that its position relative to the machine frame does not change during the construction of the winding 2. He can e.g. sit on a revolver head.

In einem nur schematisch angedeuteten Gehäuse 4, das relativ zum Maschinengestell in einer senkrechten Führung hin und herverschieblich ist, ist eine Treibwalze 5 gelagert, die durch einen nicht dargestellten Motor angetrieben ist. Der Treibwalze 5 eng benachbart ist in dem Gehäuse 4 eine Changiereinrichtung 6 untergebracht.A drive roller 5, which is driven by a motor (not shown), is mounted in a housing 4 which is only indicated schematically and which can be pushed back and forth in a vertical guide relative to the machine frame. A traversing device 6 is accommodated in the housing 4 in close proximity to the drive roller 5.

Durch unbeweglich mit dem Maschinengestell verbundene Fadenführer 7, die entsprechend der Anzahl der Wickelstellen jeweils mittig über der zugeordneten Wickelstelle angebracht sind, werden Fäden 8 mit hoher Geschwindigkeit der Changiereinrichtung 6 zugeführt, durchlaufen ein kurzes freies Wegstück, liegen anschliessend auf einem Bogen von etwas mehr als 90 Grad an der Oberfläche der Treibwalze 5 an und gelangen von dort auf die Wickel 2. Entsprechend dem zunehmenden Wickeldurchmesser weicht die Treibwalze 5 zusammen mit der Changiereinrichtung 6 nach oben aus, wie durch den Pfeil 9 symbolisiert.By immovably connected to the machine frame thread guide 7, which are attached according to the number of winding stations in the middle above the assigned winding station, threads 8 are fed to the traversing device 6 at high speed, pass through a short free path, then lie on a sheet of slightly more than 90 degrees to the surface of the driving roller 5 and from there reach the winding 2. In accordance with the increasing winding diameter, the driving roller 5, together with the traversing device 6, deviates upwards, as symbolized by the arrow 9.

Die Changiereinrichtung 6 ist in dem Gehäuse 4 an einer Traverse 10 angeordnet. Auf einer mit der Traverse 10 verschweissten Platte 11 sitzt, mittels einer Stellschraube 12 in Längsrichtung der Traverse 10 justierbar, ein Motor 13 mit gezahnter Antriebsscheibe 14. Am anderen Ende der Traverse 10 ist eine ebenfalls gezahnte Umlenkscheibe 15 auf einem Schlitten 16 gelagert, der auf Führungsstangen 17 in Längsrichtung der Traverse 10 gleitend geführt ist. Eine Spannfeder 18, die an einem Bügel 19 abgestützt ist, drückt den Schlitten 16 in Richtung auf das Ende der Traverse 10. Über die Antriebsscheibe 10 und die Umlenkscheibe 15 ist ein endloser Zahnriemen 20 geführt. Dabei ist das Obertrum 21 des Zahnriemens 20 durch zwei weitere Zahnscheiben 22, 23, die in der Nähe der Antriebsscheibe 14 bzw. der Umlenkscheibe 15 gelagert sind, so umgelenkt, dass es mit kurzem Abstand parallel dem Untertrum 24 läuft. Bei dem durch den Pfeil 25 veranschaulichten Drehsinn der Antriebsscheibe 14 läuft das Obertrum 21 in Richtung des Pfeils 26, das Untertrum 24 in entgegengesetzter Richtung gemäss Pfeil 27.The traversing device 6 is arranged in the housing 4 on a cross member 10. On a plate 11 welded to the crossmember 10, a motor 13 with a toothed drive pulley 14 sits, adjustable by means of an adjusting screw 12 in the longitudinal direction of the crossmember 10 Guide rods 17 is slidably guided in the longitudinal direction of the cross member 10. A tension spring 18, which is supported on a bracket 19, presses the carriage 16 in the direction of the end of the crossmember 10. An endless toothed belt 20 is guided over the drive pulley 10 and the deflection pulley 15. The upper run 21 of the toothed belt 20 is deflected by two further toothed pulleys 22, 23, which are mounted in the vicinity of the drive pulley 14 or the deflection pulley 15, in such a way that it runs parallel to the lower run 24 at a short distance. In the direction of rotation of drive pulley 14 illustrated by arrow 25, upper run 21 runs in the direction of arrow 26, lower run 24 runs in the opposite direction according to arrow 27.

An der von der Traverse 10 abgewandten Kante des Zahnriemens 20 sind in gleichmässigen Abständen Mitnehmer 28 befestigt.On the edge of the toothed belt 20 facing away from the cross member 10, drivers 28 are fastened at regular intervals.

Über dem Obertrum 21 ist an der Traverse 10 dicht neben der Zahnscheibe 22 ein Lagergehäuse 29 befestigt, in dem ein Zahnrad 30 mit waagerecht liegender Achse gelagert ist. An der anderen Seite der Traverse 10 ist in der Nähe der Zahnscheibe 22, die dem Motor 13 benachbart ist, ein Führungsblock 31 befestigt. Eine obere Schubstange 32 und eine untere Schubstange 33 sindzueinander und zu den beiden Trumen 21, 24 des Zahnriemens 20 parallel - in Bohrungen des Führungsblocks 31 und des Lagergehäuses 29 gleitend geführt. Beide Schubstangen 32, 33 sind im Bereich des Lagergehäuses 29 auf den einander zugekehrten Seiten mit Verzahnungen versehen, die mit dem Zahnrad 30 an 180 Grad zueinander versetzten Stellen kämmen.Above the upper run 21, a bearing housing 29 is fastened to the cross member 10 close to the toothed disk 22, in which a gear wheel 30 with a horizontally lying axis is mounted. A guide block 31 is fastened on the other side of the crossmember 10 in the vicinity of the toothed disk 22, which is adjacent to the motor 13. An upper push rod 32 and a lower push rod 33 are guided to one another and parallel to the two runs 21, 24 of the toothed belt 20 - in bores in the guide block 31 and the bearing housing 29. Both push rods 32, 33 are provided in the area of the bearing housing 29 on the mutually facing sides with toothings which mesh with the gear 30 at 180-degree offset points.

Fest auf der unteren Schubstange 33 sitzt eine Buchse 34. Eine Druckfeder 35, die an einen Widerlager 36 abgestützt ist, drückt die Buchse 34 und damit die untere Schubstange 33 in Richtung auf den Motor 13. Infolge der durch das Zahnrad 30 bewirkten gegenläufigen Kopplung wird die obere Schubstange 32 in die entgegengesetzte Richtung - in der Zeichnung nach rechts - gedrückt.A bush 34 sits firmly on the lower push rod 33. A compression spring 35, which is supported on an abutment 36, presses the bush 34 and thus the lower push rod 33 in the direction of the motor 13. As a result of the counter-rotating coupling caused by the gearwheel 30 the upper push rod 32 in the opposite direction - in the drawing to the right - pressed.

Die obere Schubstange 32 ist an der Seite, an der die Umlenkscheibe 15 angeordnet ist, über das Ende der Traverse 10 hinaus verlängert und am Ende mit einer Tastrolle 37 versehen. Diese liegt unter dem von der Feder 35 ausgeübten Druck spielfrei an einer Führungsschiene 38 an.The upper push rod 32 is extended on the side on which the deflection plate 15 is arranged, beyond the end of the cross member 10, and is provided with a sensing roller 37 at the end. This lies under the pressure exerted by the spring 35 on a guide rail 38 without play.

Die Führungsschiene 38 ist um einen Drehzapfen 39 schwenkbar, der in einer am Maschinengestell angeschweissten Gabel 39 sitzt. In der mit durchgezogen Linien dargestellten Grundstellung ist die Führungsschiene 38 senkrecht angeordnet, das Iheisstrechtwinklig zur Richtung der Trume 21, 24 und dementsprechend auch rechtwinklig zur Wickelachse. Aus dieser Stellung ist sie in der Ebene, in der die Schubstangen 32, 33 liegen, in Richtung des Pfeils 41 um einen Winkel bis zu etwa 30 Grad verschwenkbar. Innerhalb dieses Winkelbereichs ist sie in jeder Stellung - wie z.B. in der mit unterbrochenen Linien veranschaulichten Stellung 38' - mittels Stellschrauben 42, 43 arretierbar.The guide rail 38 can be pivoted about a pivot pin 39 which is seated in a fork 39 welded to the machine frame. In the basic position shown with solid lines, the guide rail 38 is arranged vertically, which is perpendicular to the direction of the strands 21, 24 and accordingly also perpendicular to the winding axis. From this position, it can be pivoted through an angle of up to approximately 30 degrees in the direction in which the push rods 32, 33 lie, in the direction of the arrow 41. It is in any position within this angular range - e.g. in the position 38 'illustrated with broken lines - can be locked by means of set screws 42, 43.

An der oberen Schubstange 32 sind Verbindungsstücke 44, 45 fest angeklemmt, die unten bis zur Höhe der Trume 21,24 reichen. Daran ist eine dünne Leiste 46 angeschraubt, die flach in dem engen Zwischenraum zwischen den Trumen 21, 24 liegt und sich nahezu über die ganze freie Länge zwischen den Zahnscheiben 22, 23 erstreckt. Die Verbindungsstücke 44, 45 sind mit Bohrungen versehen, in denen die untere Schubstange 33 frei gleitet. Die Leiste 46 ist in gleichmässigen Abständen mit insgesamt vier Abweisern 47a bis 47d (insbesondere Figur 3a) versehen, die nach vorne über die mit den Mitnehmern 28 besetzte Vorderkante des Zahnriemens 20 ein wenig weiter hinausragen als die Mitnehmer 28 selbst. Die Abweiser 47 der Leiste 46 sind an der Flanke, die dem Motor 13 zugekehrt ist - in der Zeichnung nach links - keilförmig abgeschrägt.On the upper push rod 32, connecting pieces 44, 45 are firmly clamped, which reach down to the height of the strands 21, 24. A thin strip 46 is screwed onto it, which lies flat in the narrow space between the runs 21, 24 and extends almost over the entire free length between the toothed disks 22, 23. The connecting pieces 44, 45 are provided with bores in which the lower push rod 33 slides freely. The strip 46 is provided at regular intervals with a total of four deflectors 47a to 47d (in particular FIG. 3a), which protrude slightly beyond the front edge of the toothed belt 20, which is occupied by the carriers 28, than the carriers 28 themselves. The deflectors 47 of the strip 46 are beveled in a wedge shape on the flank facing the motor 13 - to the left in the drawing.

Entsprechend ist mit der unteren Schubstange 33 durch Verbindungsstücke 48, 49, die mit Bohrungen für den gleitenden Durchgang der oberen Schubstange 32 versehen sind, eine Leiste 50 verbunden, die dicht unter der Leiste 46 ebenfalls zwischen den Trumen 21, 24 liegt. Die Leiste 50 hat vier Abweiser 51 a bis 51 d, die in gleichen Abständen wie die Abweiser 47 angeordnet und ebenso wie diese mit einer Keilschräge versehen sind, jedoch auf der gegenüberliegenden, in der Zeichnung rechten Seite. In der Stellung, die in der Zeichnung dargestellt und besonders deutlich aus Figur 3a erkennbar ist, überlappen sich die Abweiser 47a mit 51 b, 47b mit 51 c und 47c mit 51 d jeweils mit ihren breiteren Seiten.Correspondingly, a strip 50 is connected to the lower push rod 33 by means of connecting pieces 48, 49, which are provided with bores for the sliding passage of the upper push rod 32, and is also located below the strip 46 between the strands 21, 24. The strip 50 has four deflectors 51 a to 51 d, which are arranged at the same intervals as the deflectors 47 and, like these, are provided with a wedge bevel, but on the opposite side, on the right in the drawing. In the position shown in the drawing and which can be seen particularly clearly from FIG. 3a, the deflectors 47a with 51b, 47b with 51c and 47c with 51d each overlap with their wider sides.

Die schwenkbare Führungsschiene 38 kann auch durch ein leicht austauschbares Führungselement 52 mit gekrümmter Führungskante 53 ersetzt werden. In diesem Falle erhalten die Wickel 2' gewölbte Endflächen, wie in Figur4a veranschaulicht.The pivotable guide rail 38 can also be replaced by an easily exchangeable guide element 52 with a curved guide edge 53. In this case, the windings 2 ′ have curved end faces, as illustrated in FIG. 4 a.

Der in der Zeichnung dargestellten Aufspulmaschine laufen insgesamt vier Fäden 8a bis 8d zu (Figur 3a). Die Fäden 8a und 8c werden von den Mitnehmern 28a bzw. 28cdes Obertrums 21 in der Zeichnung nach rechts bewegt, die Fäden 8b und 8d von den Mitnehmern 28b und 28d des Untertrums 24 nach links. In der gezeigten Stellung sind die Fäden 8a und 8c schon mit den keilförmig ansteigenden Flanken der Abweiser 47a, 47c in Kontakt, ebenso die Fäden 8b und 8d mit den in umgekehrter Richtung abgeschrägten Flanken der Abweiser 51 b, 51 d. Die Fäden 8a und 8c befinden sich unmittelbar vor dem rechten Umkehrpunkt ihres Changierbereichs, die Fäden 8b und 8d vor dem linken Umkehrpunkt. Im folgenden Augenblick werden alle Fäden durch die Abweiser aus dem Kontakt mit dem zugehörigen Mitnehmer gelöst und kehren-bedingt durch die mittige Anordnung der Fadenführer 7 über den zugeordneten Wickelstellen - ihre Bewegungsrichtung um. Nachdem sie sich zunächst frei bewegt haben, werden sie von je einem Mitnehmer eingeholt, und zwar der Faden 8a von dem Mitnehmer 28b, der Faden 8b von dem Mitnehmer 28a, der Faden 8c von dem Mitnehmer 28d und der Faden 8d von dem Mitnehmer 28c.The winding machine shown in the drawing has a total of four threads 8a to 8d (FIG. 3a). The threads 8a and 8c are moved to the right by the drivers 28a and 28c of the upper run 21 in the drawing, the threads 8b and 8d by the drivers 28b and 28d of the lower run 24 to the left. In the position shown, the threads 8a and 8c are already in contact with the wedge-shaped rising flanks of the deflectors 47a, 47c, as are the threads 8b and 8d with the flanks of the deflectors 51b, 51d that are bevelled in the opposite direction. The threads 8a and 8c are located immediately before the right reversal point of their traversing area, the threads 8b and 8d before the left reversal point. In the following instant, all the threads are released from contact with the associated driver by the deflectors and, due to the central arrangement of the thread guides 7 above the assigned winding stations, reverse their direction of movement. After they have first moved freely, they are each caught by a driver, namely the thread 8a by the driver 28b, the thread 8b by the driver 28a, the thread 8c by the driver 28d and the thread 8d by the driver 28c.

Dieses Spiel wiederholt sich entsprechend jeweils an den entgegengesetzten Umkehrpunkten der einzelnen Changierbereiche.This game is repeated accordingly at the opposite reversal points of the individual traversing areas.

Aus dem Obigen wird klar, dass die Lage des Umkehrpunktes durch die Lage des Abweisers bestimmt ist, der die Fadenumkehr auslöst.It is clear from the above that the position of the reversal point is determined by the position of the deflector which triggers the thread reversal.

Mit zunehmendem Wickeldurchmesser weicht die Changiereinrichtung 6, wie schon beschrieben, nach oben in Richtung des Pfeils 9 aus. Dabei fährt die Tastrolle 37 an der fest mit dem Maschinengestell verbundenen Führungsschiene 38, die beispielsweise die Stellung 38' einnimmt, aufwärts und schiebt die Schubstange 32 nach links. Die Schubstange 33 bewegt sich zwangsläufig nach rechts. Mit den Schubstangen 32, 33 verschieben sich im gleichen Mass die Leisten 46,50 mit den Abweisern 47, 51. Die Abweiser 47a und 51a, die die Umkehrpunkte für den Aufbau des Wickels 2a bestimmen, bewegen sich also mit zunehmendem Wickeldurchmesser aufeinander zu, ebenso die zusammengehörenden anderen Paare von Abweisern. Der Changierhub verkleinert sich, und der Wickel wird konisch, wobei der Konus genau der Winkeleinstellung der Führungsschiene 38 entspricht.With increasing winding diameter, the traversing device 6, as already described, deviates upwards in the direction of the arrow 9. The feeler roller 37 moves upward on the guide rail 38 which is firmly connected to the machine frame and which, for example, occupies the position 38 ', and pushes the push rod 32 to the left. The push rod 33 inevitably moves to the right. With the push rods 32, 33, the strips 46, 50 with the deflectors 47, 51 move to the same extent. The deflectors 47a and 51a, which determine the reversal points for the construction of the winding 2a, therefore move towards one another with increasing winding diameter the related other pairs of deflectors. The traversing stroke is reduced and the winding becomes conical, the cone corresponding exactly to the angle setting of the guide rail 38.

Wenn die Aufspulmaschine von vier Wickelstellen auf acht entsprechend schmalere Wickelstellen umgestellt werden soll, tauscht man den Zahnriemen 20 gegen einen anderen Zahnriemen aus, der auf der gleichen Länge die doppelte Zahl von Mitnehmern aufweist. Ausserdem sind die Leisten 46, 50 gegen Leisten mit entsprechend enger angeordneten Abweisern auszutauschen. Das Getriebe für die selbsttätige Verschiebung der Abweiser bleibt unverändert; gegebenenfalls kann der Konuswinkel durch einfache Verstellung der Führungsschiene 38 geändert werden.If the winding machine is to be changed over from four winding positions to eight correspondingly narrower winding positions, the toothed belt 20 is exchanged for another toothed belt which has twice the number of drivers over the same length. In addition, the strips 46, 50 are to be replaced by strips with correspondingly closer deflectors. The gearbox for the automatic deflection of the deflectors remains unchanged; if necessary, the cone angle can be changed by simply adjusting the guide rail 38.
