Abstract

The traversing device on the cross-winding machine has a pivotable guide rule (27), by means of which a stroke reduction for producing biconical bobbins (1) takes place. For the pivoting of the rule (27), each winding station is assigned a separate drive (31). A control unit (39) on each winding station receives from a sensor (43) information relating to the instantaneous diameter (D) of the bobbin (1) and to the number of strokes of the reversing threaded roller and/or the rotational speed of the driving roller. From a central programme unit (45), the individual control units (39) receive the basic data for the deflection of the rule (27). In addition to the deflection of the rule (27) for producing the conical ends of the bobbin (1), high-frequency stroke reductions and/or disturbances to prevent ribbon windings are produced by means of the drives (31). <IMAGE>

Description

Die Erfindung betrifft eine Changiervorrichtung an einer Kreuzspulmaschine gemäss Oberbegriff des Patentanspruches 1.
Zur Herstellung von Spulen mit verkürztem Hub, sogenannten Pineapple- oder bikonische Spulen auf Spulmaschinen mit einem Kehrgewindewalzenantrieb für den Fadenführer ist es bekannt, den Fadenführer am einen Ende eines zweiarmigen Hebels zu befestigen und das andere Ende in einem um eine feste Achse schwenkbaren Lineal zu führen. Das Lineal ist um eine seitlich der Kehrgewindewalze angeordnete Achse schwenkbar befestigt und bewirkt, dass mit zunehmender Neigung des Lineals eine Hubverkürzung des Fadenführers am Ende des Hebels erfolgt.The invention relates to a traversing device on a cheese winder according to the preamble of claim 1.
For the production of bobbins with a shorter stroke, so-called pineapple or biconical bobbins on winding machines with a reverse thread drive for the thread guide, it is known to attach the thread guide to one end of a two-armed lever and to guide the other end in a ruler that can be pivoted about a fixed axis . The ruler is pivotally attached about an axis arranged on the side of the reversing thread roller and causes the thread guide at the end of the lever to be shortened as the ruler becomes inclined.

Derartige Changiereinrichtungen sind aus dem Stand der Technik bekannt. Bei allen diesen bekannten Vorrichtungen wird der Betrag der Verschwenkung des Lineals, bzw. dessen Winkellage zur Drehachse des Fadenführers über den Spulendurchmesser, bzw. die Verschiebung des Spulendornes bezüglich der Reib- oder Antriebswalze mittels einer Hebelübersetzung eingestellt. Üblicherweise erfolgt die Verschwenkung des Lineals an jeder einzelnen Spulstelle in Abhängigkeit des jeweiligen Spulendurchmessers.Such traversing devices are known from the prior art. In all these known devices, the amount of pivoting of the ruler, or its angular position to the axis of rotation of the thread guide over the bobbin diameter, or the displacement of the bobbin mandrel with respect to the friction or drive roller is set by means of a lever ratio. Usually, the ruler is pivoted at each individual winding point depending on the respective bobbin diameter.

Es ist weiter bekannt, zentral für sämtliche Spulstellen der vom Spulendurchmesser erzeugten Auslenkung eine zusätzliche Auslenkung des Lineals zu überlagern, um den Flankenwinkel der Spulen zentral einstellbar zu machen. Diese Überlagerung der Verschwenkung erfolgt mittels entlang der Maschine angebrachten Schubstangen, die an allen Spulstellen entsprechende Nocken und/oder Kurven aufweisen, welche mit den spulendurchmesserabhängigen Mechanismen zusammenwirken. Es ist weiter bekannt, den Fadenführerhub durch eine weitere überlagerte Bewegung periodisch und mit hoher Frequenz zu ändern, um sogenannt "harte" Kanten zu vermeiden.
Sämtliche Einstellungen wie der Betrag der Verschwenkung des Lineals zur Erzeugung konischer Spulenenden, als auch die periodischen Übelangerungen einer Hubverkürzung sind abhängig von der Art des aufzuspulenden Garnes, bzw. von dessen Material und Dicke.
Bei einem Wechsel auf ein anderes aufzuspulendes Garn müssen demzufolge die meisten Parameter der Hubverkürzungseinrichtung neu eingestellt werden. Dies bedeutet, dass die geometrischen Verhältnisse der verschiedenen Hebellängen an jeder Spulstelle neu eingestellt und/oder dass neue Kurven eingesetzt werden müssen. Dies ist eine aufwendige und kostspielige Arbeit. Im weiteren kann eine Änderung einzelner Parameter während des Spulens nicht erfolgen.It is also known to superimpose an additional deflection of the ruler centrally for all winding locations of the deflection generated by the coil diameter in order to make the flank angle of the coils centrally adjustable. This pivoting is superimposed by means of push rods attached along the machine, which have corresponding cams and / or curves at all winding points, which interact with the mechanisms dependent on the coil diameter. It is also known to change the thread guide stroke periodically and at a high frequency by means of a further superimposed movement in order to avoid so-called “hard” edges.
All settings such as the amount of pivoting of the ruler to produce conical bobbin ends, as well as the periodic lengthening of a stroke shortening, depend on the type of yarn to be wound, or on its material and thickness.
When changing to another yarn to be wound up, most of the parameters of the stroke shortening device must therefore be reset. This means that the geometrical relationships of the different lever lengths at each winding point are reset and / or that new curves have to be used. This is an elaborate and costly job. Furthermore, individual parameters cannot be changed during winding.

Hier will die Erfindung Abhilfe schaffen.
Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, eine Changiervorrichtung an einer Kreuzspulmaschine für die Herstellung von Spulen mit konischen Enden zu schaffen, mit welcher die Konizität der Spulenenden, die Atmung, die periodische Hubvariation einzelner Spulstellen und/oder Sektionen und/oder der gesamten Spulmaschine ohne Änderungen an mechanischen Elementen ein- und verstellbar ist.The invention seeks to remedy this.
The invention, as characterized in claim 1, solves the problem of creating a traversing device on a cheese winding machine for the production of coils with conical ends, with which the conicity of the coil ends, breathing, the periodic stroke variation of individual Winding units and / or sections and / or the entire winding machine is adjustable and adjustable without changes to mechanical elements.

Durch den Einsatz eines individuellen Schwenkantriebes für den Lineal an jeder einzelnen Spulstelle können sämtliche für den Aufbau notwendigen Parameter mit Ausnahme des die Hubverstellung bewirkenden zweiarmigen Hebels eingestellt werden. Die Überlagerung von Hubvariationen mit hoher Frequenz und/oder die Veränderung des Böschungswinkels an den Spulenenden kann mit demselben Stellglied, nämlich dem Schwenkantrieb an jeder Spulstelle und unabhängig von der benachbarten erfolgen. Die Veränderungen der Parameter lassen sich in einfacher Weise an jeder Spulstelle, sektionsweise oder für die gesamte Maschine jederzeit, d.h. auch während des Betriebes ein- und verstellen. Es können der Steuerung für die einzelnen oder für sämtliche Antriebe beliebige Parameterkombinationen eingegeben und/oder gespeichert werden, so dass bei einem Garnwechsel nicht sämtliche Parameter neu eingestellt, sondern nur aus dem Speicher abgerufen werden können. Für erstmals verarbeitete Garne können die Parameter eingegeben und gespeichert werden.
Der direkte Angriff des Stellantriebes am Lineal ermöglicht eine spielfreie Übertragung der zum Beispiel in Abhängigkeit des Spulendurchmessers berechneten Daten auf den Lineal. Die Erfassung des Spulendurchmessers, bzw. des Drehwinkels des Spulendorntragarmes kann in einfacher und exakter Weise durch einen Winkelgeber oder durch Berechnung aus der Stellung des Winkelgebers erfolgen und der Steuerung jeder einzelnen Spulstelle oder einer zentralen Steuerung zugeleitet werden. Die Bedienungsperson kann bei Änderungen der Spezifikation des aufzuspulenden Garnes optisch festgestellte Unregelmässigkeiten jederzeit durch eine Korrektur entsprechender Parameter an jeder einzelnen, an Gruppen oder an sämtlichen Spulstellen beheben.By using an individual swivel drive for the ruler at each individual winding unit, all parameters necessary for the assembly can be set, with the exception of the two-armed lever that effects the stroke adjustment. The superimposition of stroke variations with a high frequency and / or the change of the slope angle at the coil ends can be carried out with the same actuator, namely the swivel drive at each winding point and independently of the neighboring one. The changes to the parameters can be made and adjusted at any winding position, section by section or for the entire machine at any time, ie also during operation. Any combination of parameters can be entered and / or saved in the control for the individual drives or for all drives, so that when changing the yarn, not all parameters are reset, but can only be called up from the memory. The parameters can be entered and saved for yarns processed for the first time.
The direct attack of the actuator on the ruler enables play-free transfer of the data calculated, for example, depending on the coil diameter to the ruler. The detection of the bobbin diameter or the angle of rotation of the bobbin support arm can be carried out in a simple and exact manner by an angle encoder or by calculation from the position of the angle encoder and can be fed to the control of each individual winding unit or a central control. The operator can change the specification of the yarn to be wound Eliminate visually determined irregularities at any time by correcting the corresponding parameters at each individual, at groups or at all winding units.

Anhand eines illustrierten Ausführungsbeispieles wird die Erfindung näher erläutert. Es zeigen:

  • Figur 1 eine schematische Darstellung einer Vorrichtung zur Hubverkürzung an einer Kreuzspulmaschine und
  • Figur 2 einen Querschnitt durch eine Spulstelle.
The invention is explained in more detail with the aid of an illustrated embodiment. Show it:
  • Figure 1 is a schematic representation of a device for shortening the stroke on a cheese winder and
  • Figure 2 shows a cross section through a winding unit.

Eine bikonische Spule 1 auf einer Hülse 3 ist drehbar um die Achse A an zwei Schwenkarmen 5 am Maschinengestell 7 einer in der Figur nur andeutungsweise dargestellten Spulmaschine drehbar gelagert. Der Antrieb der Spule 1 erfolgt über eine Reibwalze 9, auf der die Spule 1 linienförmig aufliegt.A biconical bobbin 1 on a sleeve 3 is rotatably supported about the axis A on two swivel arms 5 on the machine frame 7 of a bobbin winder, which is only indicated in the figure. The coil 1 is driven by a friction roller 9 on which the coil 1 rests in a linear manner.

Für die Verlegung des Fadens 11 ist vor dem von einer Lieferspule 13 zugeführten Faden 11 eine Kehrgewindewalze 15, um eine Achse B antreibbar angeordnet. Ein Nutenstein 19 wird längs den parallel zur Achse B verlaufenden Führungskanten 17 durch die Kehrgewindewalze 15 axial hin und her bewegt. Ein zweiarmiger Hebel 21 ist schwenkbar am Nutenstein 19 befestigt. Das eine freie Ende des Hebels 21 ist als Fadenführer 23 ausgebildet, das andere freie Ende ist schwenkbar mit einem Gleiter 25 verbunden, welcher in einer Führungsschiene, im folgenden Führungslineal 27 genannt, längsgeführt ist. Das Führungslineal 27 ist um eine Achse C schwenkbar gelagert.For the laying of the thread 11, a reversing thread roller 15 is arranged in front of the thread 11 fed from a delivery spool 13 and can be driven about an axis B. A sliding block 19 is moved axially back and forth along the guide edges 17 running parallel to the axis B by the reversing thread roller 15. A two-armed lever 21 is pivotally attached to the sliding block 19. One free end of the lever 21 is designed as a thread guide 23, the other free end is pivotally connected to a slider 25 which is longitudinally guided in a guide rail, hereinafter called guide ruler 27. The guide ruler 27 is pivotally mounted about an axis C.

Im dargestellten Beispiel ist der zweiarmige Hebel 21 als Winkelhebel ausgebildet und an der Verbindungsstelle der beiden Schenkel auf dem Nutenstein 19 schwenkbar gelagert. Die Ausbildungen der Kehrgewindewalze 15, des zweiarmigen Hebels 21 sowie deren gelenkige Verbindungen sind nicht Gegenstand der vorliegenden Erfindung und gehören zum Stand der Technik, wie er beispielsweise in der Schweizer Patentschrift 542 132 beschrieben wird.In the example shown, the two-armed lever 21 is designed as an angle lever and is pivotably mounted on the sliding block 19 at the junction of the two legs. The designs of the reversing thread roller 15, the two-armed lever 21 and their articulated connections are not the subject of the present invention and belong to the prior art, as described, for example, in Swiss Patent 542,132.

Gemäss den Merkmalen der Erfindung ist das eine Ende 29 des Führungslineals 27 mit einem eigenen Schwenkantrieb 31 verbunden. In der Figur 1 besteht dieser Antrieb aus einem Elektromotor 33 mit einem Abtriebsritzel 35, welches mit einem bogenförmigen Zahnsegment 37 am Lineal 27 kämmt. Die Krümmung des Zahnsegmentes 37 entspricht der Mantelkurve mit Drehzentrum um die Achse C. Anstelle,eines Elektromotors 33 mit Drehantrieb könnte auch ein Linearantrieb vorgesehen sein, dessen Abtriebsseite gelenkig mit dem Ende 29 des Führungslineales 27 verbunden ist. Bei dieser Ausführung ergibt sich bei linearer Antriebsbewegung eine nicht lineare Schwenkung des Lineals 27.According to the features of the invention, one end 29 of the guide ruler 27 is connected to its own swivel drive 31. In FIG. 1, this drive consists of an electric motor 33 with an output pinion 35, which meshes with an arcuate toothed segment 37 on the ruler 27. The curvature of the toothed segment 37 corresponds to the jacket curve with a center of rotation about the axis C. Instead of an electric motor 33 with a rotary drive, a linear drive could also be provided, the driven side of which is articulated to the end 29 of the guide ruler 27. In this embodiment, there is a non-linear pivoting of the ruler 27 with a linear drive movement.

Jeder Spulstelle ist eine Steuereinheit 39 zugeordnet, welche den Antrieb 31 steuert. Jede Steuereinheit 39 ist entweder mit einem Sensor 41 verbunden, der die momentane Winkellage der Schwenkarme 5 und damit indirekt den aktuellen Durchmesser D der Spule 1 erfasst, oder die Winkellage wird anhand anderer Parameter errechnet. Im weiteren werden der Steuereinheit 39 Referenzsignale über die Drehzahl der Antriebswalze 9 und/oder der Kehrgewindewalze 15 durch einen nur schematisch dargestellten Sensor 43 mitgeteilt. Jede Steuereinheit 39 ist weiterhin mit einer Programmeinheit 45 verbunden. Die Programmeinheit 45 ist mit sämtlichen Steuereinheiten 39 auf der Maschine verbunden und dient dazu, die Parameter für den Aufbau einer Spule 1 einerseits zu speichern und andererseits die entsprechenden Signale an die Steuereinheiten 39 jeder einzelnen Spulstelle zu übermitteln. Die Programmeinheit 45 kann als frei programmierbare Steuerung aufgebaut sein. Sie dient gleichzeitig der Bedienungsperson dazu, einzelne Parameter einzustellen, zu verändern oder zu speichern. Die Einstellung, bzw. Veränderung von Parametern kann als Gesamtes für sämtliche Spulstellen erfolgen. Sie kann aber auch nur einzelne Spulgruppen oder individuelle Spulstellen erfassen. Es besteht damit die Möglichkeit, auf einer Spulmaschine unterschiedliche Garne gleichzeitig aufzuspulen oder bei Fadenbruch den Spulaufbau unabhängig von den benachbarten Spulen mit den richtigen Parametern zu Ende zu führen.A control unit 39, which controls the drive 31, is assigned to each winding unit. Each control unit 39 is either connected to a sensor 41, which detects the current angular position of the swivel arms 5 and thus indirectly the current diameter D of the coil 1, or the angular position is calculated using other parameters. In addition, the control unit 39 is informed of reference signals about the speed of the drive roller 9 and / or the reversing thread roller 15 by a sensor 43 which is only shown schematically. Each control unit 39 is also connected to a program unit 45. The program unit 45 is connected to all the control units 39 on the machine and serves to store the parameters for the construction of a coil 1 on the one hand and the parameters on the other to transmit corresponding signals to the control units 39 of each individual winding unit. The program unit 45 can be constructed as a freely programmable control. At the same time, it serves the operator to set, change or save individual parameters. The setting or changing of parameters can be done as a whole for all winding units. However, it can also only detect individual winding groups or individual winding units. It is therefore possible to wind up different yarns simultaneously on one winding machine or, in the event of a thread break, to finish the winding process with the correct parameters independently of the adjacent bobbins.

Mit dem separaten Antrieb 31 an jeder Spulstelle kann nicht nur der Winkel alpha zwischen der Achse B der Kehrgewindewalze 15 und dem Führungslineal 27 eingestellt werden, sondern durch einen periodischen kurzzeitigen Antrieb des Ritzels 35 lassen sich zur Vermeidung harter Spulenkanten Hubvariationen im Randbereich der Spule 1 erzeugen. Zur Verhinderung von Bildwicklungen können durch den Antrieb 31 zudem Bildstörungen erzeugt werden. Die Bildstörungen können fest einprogrammiert oder durch einen Zufallsgenerator ausgelöst werden.With the separate drive 31 at each winding point, not only can the angle alpha between the axis B of the reversing thread roller 15 and the guide ruler 27 be set, but by periodically briefly driving the pinion 35, stroke variations in the edge region of the coil 1 can be generated to avoid hard bobbin edges . In order to prevent image windings, image disturbances can also be generated by the drive 31. The image disturbances can be programmed in permanently or triggered by a random generator.
