Description

Die Erfindung bezieht sich auf eine Vorrichtung für die Anlaufsteuerung von Spulengattern für Zettel-oder Schärmaschinen, deren reihen- und zeilenweise angeordneten Spulstellen je ein mit einer Wächternadel eine Fadenumlen­kung bewirkender Fadenwächter und je eine Fadenklemme zuge­ordnet sind, von der ein Faden zwischen einem Widerlager und einer damit zusammenwirkenden, begrenzt beweglichen Klemmbacke klemmbar ist, die unter Einwirkung eines Steuer­organs, insbesondere einer Steuerfeder steht, deren Klemm­kraft im zwischen Klemmstellung und Offenstellung vorhande­nen Klemmenwirkungsbereich während des Maschinenanlaufs von einer alle Fadenklemmen gemeinsam beaufschlagenden Verstellvorrichtung steuerbar ist.The invention relates to a device for the start-up control of bobbin creels for slip or warping machines, the winding positions of which are arranged in rows and rows, each with a thread monitor causing a thread deflection with a guard needle and a thread clamp each, of which a thread is connected between an abutment and one interacting, limited movement jaw is clampable, which is under the action of a control member, in particular a control spring, the clamping force in the existing between the clamp position and the open position clamping range of action during machine start-up can be controlled by an adjusting device acting jointly on all thread clamps.

Eine derartige Vorrichtung ist aus der DE-OS 34 36 714 bekannt. Die bekannte Fadenklemme hat eine horizontale Klemmbacke, die einen horizontal verlaufenden Faden gegen die Unterseite eines plattenförmigen horizon­talen Widerlagers drückt. Dies erfolgt durch eine eben­ falls horizontal wirkende Stellstange, die auf ein Ende einer Blattfeder einwirkt, deren anderes Ende beim Klemmen bzw. Bremsen des Fadens an einem in Stellrichtung unver­schieblichen Spannstück festliegt. Die Klemmbacke der Fa­denklemme ist etwa an der Mitte dieser Blattfeder be­festigt. Infolge dieser Ausgestaltung führt die Klemmbacke bei der Beaufschlagung des Fadens eine in Betätigungsrich­tung der Stellstange und damit in Längsrichtung des Wider­lagers erfolgende Relativbewegung zu diesem Widerlager durch. Außerdem hat auch die Klemmkraft eine zum Widerlager schräge Ausrichtung, woraus sich Komplikationen während des Maschinenanlaufs ergeben. Insbesondere bei dünnen gedrillten Fäden kann sich bei entsprechendem Schlag eine Tendenz zum Aufdrehen des Fadens ergeben, was mit entsprechenden Faden­verschiebungen bzw. Verlagerungen an der Fadenbremsstelle verbunden ist und die gewünschte korrekte Einflußnahme auf die Fadenbremsung verhindert.Such a device is known from DE-OS 34 36 714. The known thread clamp has a horizontal jaw that presses a horizontal thread against the underside of a plate-shaped horizontal abutment. This is done by an even if horizontally acting control rod, which acts on one end of a leaf spring, the other end of which, when the thread is clamped or braked, is fixed to a clamping piece which cannot be displaced in the adjusting direction. The jaw of the thread clamp is attached approximately to the middle of this leaf spring. As a result of this configuration, when the thread is acted on, the clamping jaw performs a relative movement to this abutment in the actuating direction of the adjusting rod and thus in the longitudinal direction of the abutment. In addition, the clamping force has an oblique orientation to the abutment, which results in complications during the machine start-up. In particular with thin twisted threads, a tendency to untwist the thread can result with a corresponding impact, which is associated with corresponding thread displacements or displacements at the thread braking point and prevents the desired correct influence on the thread braking.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Spulengatter der eingangs genannten Art bezüglich seiner Fadenklemmen so zu verbessern, daß ein einwandfreies Ab­bremsen der Fäden bei allen möglichen Fadenausbildungen problemlos durchgeführt werden kann.The invention is therefore based on the object of improving a creel of the type mentioned with regard to its thread clamps in such a way that the threads can be braked properly with all possible thread configurations.

Diese Aufgabe wird dadurch gelöst, daß die Klemmbacke bei der Klemmkraftsteuerung in Richtung der Längserstreckung des Widerlagers relativbewegungsfrei ausgebildet und ihre Klemmkraft ausschließlich senkrecht zur Widerlagerfläche gerichtet ist.This object is achieved in that the clamping jaw is designed to be relatively free of movement in the control of the clamping force in the direction of the longitudinal extent of the abutment and its clamping force is directed exclusively perpendicular to the abutment surface.

Für die Erfindung ist von Bedeutung, daß auf die Be­wegung der Klemmbacke während der Klemmkraftsteuerung ein Einfluß genommen wird, der Relativbewegungen in Richtung der Längserstreckung des Widerlagers nicht mehr zuläßt.It is important for the invention that an influence is exerted on the movement of the clamping jaw during the clamping force control, which no longer permits relative movements in the direction of the longitudinal extent of the abutment.

Vielmehr wird die Klemmkraft ausschließlich senkrecht zur Widerlagerfläche aufgebracht, so daß der Fadenlauf bzw. die Klemmstelle innerhalb der Fadenklemme nicht durch Ein­flußgrößen aus der Fadenklemme selbst veränderbar ist.Rather, the clamping force is applied exclusively perpendicular to the abutment surface, so that the thread run or the clamping point within the thread clamp cannot be changed by influencing variables from the thread clamp itself.

Es gibt eine Vielzahl konstruktiver Möglichkeiten, die vorgenannte Führung oder Einflußnahme auf die Klemm­backe zu erreichen. Vorteilhaft ist es jedoch, wenn die von der Steuerfeder beaufschlagte Klemmbacke von einem beweglichen, senkrecht zur Widerlagerfläche und zum Faden angeordneten Bolzen gehalten ist. In diesem Fall kann dem Bolzen exakt die gewünschte Bewegungsrichtung der von der Steuerfeder beaufschlagten Klemmbacke erteilt werden und es erübrigen sich zusätzliche Führungsmaßnahmen. In diesem Sinne ist der Bolzen in einem die Widerlagerfläche aufwei­senden Klemmengehäuse axial verschieblich gelagert und durchsetzt die bewegliche Klemmbacke radialspielfrei, wobei das backenrückseitige Bolzenende mit beweglichem Axialspiel an der Klemmbacke angreift, damit einerseits die gewünschte Klemmkraftsteuerung und andererseits ein definiertes Klemm­verhalten erreicht werden kann. Das Axialspiel zwischen Klemmbacke und Bolzenende wird dadurch erreicht, daß die Klemmbacke rückseitig vorspringende Betätigungslappen mit bolzenparallelen Schlitzen hat, in die ein Querstift des Bolzens eingreift.There are a variety of constructive ways to achieve the aforementioned guidance or influence on the jaw. However, it is advantageous if the clamping jaw acted upon by the control spring is held by a movable bolt arranged perpendicular to the abutment surface and to the thread. In this case, the bolt can be given exactly the desired direction of movement of the clamping jaw acted upon by the control spring, and additional guide measures are unnecessary. In this sense, the bolt is axially displaceably mounted in a clamp housing that has the abutment surface and penetrates the movable jaw without radial play, the back of the bolt acting on the jaw with movable axial play, so that the desired clamping force control and a defined clamping behavior can be achieved on the one hand. The axial play between the jaw and the end of the bolt is achieved in that the jaw has projecting actuating tabs on the back with slots parallel to the bolt, into which a transverse pin of the bolt engages.

Um die Ausgestaltung der Steuerfeder auf den sie bzw. die Fadenklemme beeinflussenden bzw. steuernden Bolzen optimal abzustimmen, umgibt die die Klemmbacke beaufschla­gende Steuerfeder den Bolzen und stützt sich andernends an dem Querstift des Bolzens ab.In order to optimally match the design of the control spring to the bolt influencing or controlling the thread clamp, the control spring acting on the clamping jaw surrounds the bolt and is supported at the other end on the cross pin of the bolt.

Von Bedeutung ist desweiteren, daß die Klemmbacke aus ihrer Fadenklemmstellung heraus entgegen der sie beauf­schlagenden Steuerfeder zum Bolzen begrenzt beweglich ange­ ordnet ist. Es ist infolgedessen insbesondere bei einer Steuerfeder mit flacher Kennlinie möglich, unterschied­lich dicke Fäden mit der Fadenklemme zu Klemmen, ohne die Klemm- und Steuercharakteristik der Fadenklemme zu beeinflussen. Auch Bautoleranzen der Fadenklemme lassen sich so einwandfrei beherrschen.It is also important that the jaw from its thread clamping position against the control spring acting on it to the bolt is limited movable is arranged. As a result, in particular in the case of a control spring with a flat characteristic, it is possible to clamp threads of different thicknesses with the thread clamp without influencing the clamping and control characteristics of the thread clamp. Construction tolerances of the thread clamp can also be controlled perfectly.

Der Bolzen ist von einer im Klemmengehäuse abgestütz­ten Klemmfeder beaufschlagt, die den Bolzen bei Klemmstel­lung der Klemmbacke unter Überwindung der Kraft der Steuer­feder in einer Anlagestellung am Gehäuse hält. Hierdurch hat der Bolzenstift eine definierte Ruhelage im Gehäuse, durch die auch erreicht wird, daß die Kraft der Steuerfeder in Klemmstellung der Fadenklemme einen einzigen definier­ten Wert hat.The bolt is acted upon by a clamping spring which is supported in the terminal housing and which holds the bolt in a contact position on the housing when the clamping jaw is in the clamping position while overcoming the force of the control spring. As a result, the pin has a defined rest position in the housing, which also ensures that the force of the control spring in the clamping position of the thread clamp has a single defined value.

In Ausgestaltung der Erfindung weist die Fadenklemme ein den Faden oberhalb des Bolzens haltendes Fadenleitele­ment auf. Damit wird ein Abrieb des Fadens am Bolzen und weitgehend auch an den Klemmenteilen vermieden, so daß die Leichtgängigkeit des Bolzens damit die Steuerung der Faden­klemme nicht ungewollt durch Fadenabrieb bzw. Schwergängig­keit des Bolzens beeinflußt werden kann.In an embodiment of the invention, the thread clamp has a thread guide element holding the thread above the bolt. An abrasion of the thread on the bolt and largely also on the clamp parts is thus avoided, so that the ease of movement of the bolt and the control of the thread clamp cannot be influenced unintentionally by thread abrasion or stiffness of the bolt.

Desweiteren ist an dem die Widerlagerfläche bildenden Widerlager ein die vertikale Fadenauslenkung nach oben begrenzender Vorsprung vorhanden. Der Vorsprung besitzt ferner auch eine im wesentlichen vertikale, quer dazu ge­richtete Fadenauslenkungen begrenzende Fadenleitkante. Durch die vorstehenden Ausgestaltungen der Fadenklemme wird eine Zwangsführung des Fadens in deren Klemmbereich bewirkt. Der Faden ist nicht in der Lage, Lageänderungen im Bereich der Fadenklemme derart vorzunehmen, daß deren die Steuerung bewirkenden Elemente durch die im Faden steckende Dynamik beeinflußbar sind. Dabei liegt die Höhe der Fadenklemmstelle relativ zur Klemmbacke praktisch fest, so daß beispielsweise deren toleranzbedingtes Kippspiel um eine horizontale Achse keinen Einfluß auf die Klemmung bzw. Steuerung der Fadenklemmung hat. Da­rüber hinaus wird durch die vorbeschriebene Führung des Fadens im Klemmbereich der Fadenklemme bzw. die Festle­gung der Fadenlaufstelle in der Fadenklemme erreicht, daß die Wächternadel aus dem Fadenlauf herrührenden ungewoll­ten dynamischen Einflüssen nicht ausgesetzt ist. Insbeson­dere braucht die Wächternadel nicht benutzt zu werden, um vertikale Fadenauslenkungen zu begrenzen.Furthermore, on the abutment forming the abutment surface there is a projection which limits the vertical thread deflection upwards. The projection also has an essentially vertical thread guide edge which delimits thread deflections directed transversely thereto. Due to the above configurations of the thread clamp, the thread is forced into its clamping area. The thread is not able to make changes in position in the area of the thread clamp in such a way that the elements causing the control can be influenced by the dynamics in the thread. The height is there the thread clamping point practically fixed relative to the clamping jaw, so that, for example, its tolerance-related tilting play about a horizontal axis has no influence on the clamping or control of the thread clamping. In addition, the above-described guiding of the thread in the clamping area of the thread clamp or the fixing of the thread running point in the thread clamp ensures that the guard needle is not exposed to undesired dynamic influences resulting from the thread path. In particular, the guard needle need not be used to limit vertical thread deflections.

Infolgedessen ist es bei Spulengattern für Zettel- oder Schärmaschinen, deren reihen- und zeilenweise ange­ordneten Spulstellen je ein mit einer Wächternadel eine Fadenumlenkung bewirkender Fadenwächter und je eine Faden­klemme zugeordnet sind, mit einem von Teilen des Klemmenge­häuses gebildeten im wesentlichen vertikalen Einlegeschlitz des in die Fadenklemme einzulegenden Fadens möglich, daß das obere Ende der Wächternadel bei allen möglichen Nadel­stellungen schlitzüberdeckungsfrei angeordnet ist. Der Faden kann also problemlos eingelegt werden, ohne daß die Konstruktion der Fadenklemme darauf Rücksicht nehmen müßte, den Faden in eine bestimmte Relativlage zum Ende der Wäch­ternadel zu bringen bzw. ohne die Gefahr, daß der einge­legte Faden aus dem Höhenbereich der Wächternadel heraus gerät und infolgedessen eine Wächterung nicht möglich ist.As a result, in the case of bobbins for slip machines or warping machines, the bobbins of which are arranged in rows and rows, one thread monitor with a guard needle causing a thread deflection and one thread clamp each are assigned, with an essentially vertical insertion slot of the part to be inserted into the thread clamp formed by parts of the terminal housing Fadens possible that the upper end of the watchdog needle is arranged without slot overlap in all possible needle positions. The thread can therefore be inserted without any problems, without the construction of the thread clamp having to take into account the need to bring the thread into a specific relative position to the end of the guard needle or without the risk that the inserted thread will get out of the height region of the guard needle and as a result guarding is not possible.

In diesem Sinne ist das Nadelende vorteilhafterweise oberhalb eines die vertikale Fadenauslenkung nach oben begrenzenden Vorsprungs und gehäuseseitig neben den Einle­geschlitz angeordnet, wobei der Fadenauslenkungen nach oben begrenzenden Vorsprung mit Sicherheit verhindert, daß der Faden nicht aus dem eine Wächterung ermöglichenden Höhenbe­reich der Wächternadel gelangt.In this sense, the needle end is advantageously arranged above a protrusion that delimits the vertical thread deflection upwards and on the housing side next to the insertion slot, the thread deflection upwardly delimiting protrusion reliably preventing the thread from coming out of the height range of the guarding needle that enables it to be monitored.

Die in Fig. 1 dargestellte Vorrichtung für die Anlauf­steuerung von Spulengattern ist eine von vielen zur Beein­flussung des Laufs eines Fadens 4 von einer mit einer Spule 22 versehenen Spulstelle 1 in Richtung des Pfeils 23 zu einer nicht dargestellten Wickelmaschine. Diese Wickel­maschine wickelt alle Fäden des Spulengatters 4 auf, die dabei jeweils eine Vorrichtung unter Umlenkung an einer Wächternadel 2 durchlaufen. Wesentlicher Bestandteil dieser Vorrichtung, die insbesondere für sogenannte V-Gatter ver­wendet wird, deren Fadenlaufgeschwindigkeiten vergleichs­weise groß sind, sind eine Fadenklemme 3 und ein Faden­wächter mit einer Wächternadel 2. Der durchlaufende Faden 4 umschlingt die Wächternadel 2 teilweise und hält diese infolge ihrer Fadenspannung in einer Stellung, in der ein mit ihr zusammenwirkender, in Fig. 4 skizzierter Signal­geber 24 des Fadenwächters ein Signal nicht gibt. Erfolgt jedoch ein Fadenbruch und läßt infolgedessen die Faden­spannung nach, so verursacht die Wächternadel 2 eine Signalgabe und damit ein Stillsetzen der Wickelmaschine. Außerdem werden die anderen Fäden 4 gespannt gehalten, damit kein die Fadenschar durch Fadendurchhang beein­trächtigender Fadenwirrwar entsteht. Außerdem muß dafür gesorgt werden, daß der Wiederanlauf gesteuert vor sich geht, damit von Anfang an eine Wächterung der Fadenschar erfolgt. Die sich aus diesen Betriebserfordernissen er­gebenen Anforderungen, welche auch von der beschriebenen Vorrichtung erfüllt werden müssen, sind ausführlich in Fig. 8 der DE-OS 34 36 714 beschrieben. Hierauf und auf die zugehörige Beschreibung wird Bezug genommen.1 is one of many for influencing the running of a thread 4 from a bobbin 1 provided with a bobbin 22 in the direction of arrow 23 to a winding machine (not shown). This winding machine winds up all threads of the creel 4, each of which passes through a device with deflection on a guard needle 2. An essential part of this device, which is used in particular for so-called V-gates, whose thread speeds are comparatively high, are a thread clamp 3 and a thread monitor with a guard needle 2. The continuous thread 4 loops around the guard needle 2 and keeps it in one because of its thread tension Position in which a signal transmitter 24 of the thread monitor which interacts with it and is outlined in FIG. 4 does not give a signal. He follows However, a thread break and consequently the thread tension decreases, the watchdog needle 2 causes a signal and thus a stoppage of the winding machine. In addition, the other threads 4 are kept taut so that there is no tangled thread which would impair the thread family due to thread sag. In addition, it must be ensured that the restart is controlled so that the thread set is monitored from the start. The requirements resulting from these operating requirements, which must also be met by the device described, are described in detail in Fig. 8 of DE-OS 34 36 714. Reference is made to this and to the associated description.

Die in den Fig. dargestellte Vorrichtung hat ein Klemmengehäuse 11, welches die Fadenklemme 3 und den Faden­wächter aufnimmt bzw. lagert. Die Fadenklemme 3 besteht im wesentlichen aus einem Widerlager 5 und einer Klemmbacke 6, die zu dem Widerlager 5 relativbeweglich ist. Diese Bauteile sind an einem Gehäusekörper 25 angebracht, der ringsum geschlossen ist und nadelseitig zum Einbau von Teilen der Fadenklemme 3 und des Fadenwächters eine Einbauöffnung 26 hat, die von einem Abdeckblech 27 verschlossen ist, das mit Befestigungsschrauben 28 an dem Gehäusekörper 25 befestigt ist. Das Abdeckblech 27 hat noch einen gemäß Fig. 3 vor­springenden und zumindest Teile eines Einlegeschlitzes 20 bildenden Blechhaken 37 mit einer rombusförmigen Ausnehmung 38. Außerdem ist der Blechhaken 37 an seinem freien Ende gemäß Fig. 1 über einen Drahtbügel 40 mit dem Klemmengehäuse 11 bzw. dessen dem Abdeckblech 27 gegenüberliegenden Gehäuse­seite verbunden, wobei der Bügel 40 ein Fadenleitelement 17 bildet, welches dem Faden 4 nicht gestattet, sich tiefer abzusenken.The device shown in the figures has a clamp housing 11 which receives or supports the thread clamp 3 and the thread monitor. The thread clamp 3 consists essentially of an abutment 5 and a jaw 6, which is relatively movable to the abutment 5. These components are attached to a housing body 25 which is closed all round and has an installation opening 26 on the needle side for the installation of parts of the thread clamp 3 and the thread monitor, which is closed by a cover plate 27 which is fastened to the housing body 25 with fastening screws 28. The cover plate 27 also has a protruding sheet metal hook 37 according to FIG. 3 and at least parts of an insertion slot 20 with a diamond-shaped recess 38. In addition, the sheet metal hook 37 is at its free end according to FIG. 1 via a wire bracket 40 with the terminal housing 11 or its connected to the cover plate 27 opposite the housing side, the bracket 40 forming a thread guide element 17, which does not allow the thread 4 to lower deeper.

Das Abdeckblech 27 lagert die Wächternadel 2 mit einem Drehzapfen 29, der in ein auf der anderen Seite des Abdeck­blechs 27 angeordnetes Hülsenstück 31 eingesetzt ist und mit einem freien Ende in einen angeformten Stutzen 32 des Gehäuse­körpers 25 eingreift. An dem Hülsenstück 31 ist ein Kontakt­finger 33 angebracht, der für eine Signalabgabe des Signal­gebers 24 sorgt, wenn er aus seiner in den Fig. 3, 4 darge­stellten Stellung zur Anlage an dem mit zwei Kontaktfahnen 35 versehenen Signalgeber 24 kommt. Das ist der Fall, wenn die Wächternadel 2 aus der in Fig. 3 ersichtlichen Lage im Uhrzeigersinn abkippt, was sie wegen ihres rechts von dem Achsstift 29 gelegenen Schwerpunkts infolge der Einwirkung der Schwerkraft tut. In Kipplage ragt die Wächternadel 2 nicht in den unten erläuterten Einlegeschlitz 20 für den Faden 4.The cover plate 27 supports the guard needle 2 with a pivot 29 which is inserted into a sleeve piece 31 arranged on the other side of the cover plate 27 and engages with a free end in a molded connection piece 32 of the housing body 25. A contact finger 33 is attached to the sleeve piece 31, which ensures that the signal transmitter 24 emits a signal when it comes to rest against the signal transmitter 24 provided with two contact tabs 35 from its position shown in FIGS. 3, 4. This is the case when the guard needle 2 tilts clockwise from the position shown in FIG. 3, which it does because of its center of gravity located to the right of the axle pin 29 as a result of the action of gravity. In the tilted position, the guard needle 2 does not protrude into the insertion slot 20 for the thread 4 explained below.

Die Wächternadel 2 ist mit ihrem unteren abgewinkelten Ende in eine Bohrung des Achsstifts 29 gesteckt und an diesem mit einer nicht dargestellten Madenschraube befestigt, die mit einer aus Fig. 6 ersichtlichen Innenmehrkantausneh­mung 30 betätigt wird. In ihrer in Fig. 3 dargestellten Stellung, in der sie durch den gespannten Faden 4 gehalten wird, verläuft ihr mittlerer, der Fadenumlenkung dienender Nadelabschnitt etwa parallel zu der Frontfläche 11′ des Klemmengehäuses 11. Das obere Ende 21 der Wächternadel 2, die im ganzen etwa blechparallel angeordnet ist, ist in Richtung auf den Boden 36 des Körpers 25 zurückgebogen, wobei ihre Neigung gegen den fadenführenden Abschnitt der Nadel 2 entgegengesetzt gleichgroß derjenigen Neigung des unteren Endes der Nadel 2 ist.The guard pin 2 is inserted with its lower angled end into a bore in the axle pin 29 and fastened to it with a grub screw, not shown, which is actuated with an internal polygon recess 30 shown in FIG. 6. In its position shown in Fig. 3, in which it is held by the tensioned thread 4, its middle, the thread deflection serving needle section runs approximately parallel to the front surface 11 'of the terminal housing 11. The upper end 21 of the guard needle 2, the whole is arranged approximately parallel to the sheet, is bent back towards the bottom 36 of the body 25, its inclination towards the thread-guiding section of the needle 2 being opposite to the inclination of the lower end of the needle 2.

Das Widerlager 5 ist ein im Querschnitt im wesent­lichen L-förmiges Blechteil, das in eine entsprechend ge­formte Ausnehmung des Gehäusekörpers 25 eingebaut ist und bündig mit dessen Außenflächen liegt. Seine Befestigung erfolgt gemäß Fig. 4 und mit Befestigungsschrauben 39. Das Widerlager 5 hat eine dem Faden 4 zugewendete Wider­lagerfläche 9.The abutment 5 is a substantially L-shaped sheet metal part in cross section, which is installed in a correspondingly shaped recess in the housing body 25 and lies flush with the outer surfaces thereof. Its attachment 4 and with fastening screws 39. The abutment 5 has an abutment surface 9 facing the thread 4.

Außerdem hat das Widerlager 5 eine Bohrung, die von einem Bolzen 10 durchsetzt wird, und zwar im wesentlichen radialspielfrei und vertikal zu der Widerlagerfläche 9.In addition, the abutment 5 has a bore through which a bolt 10 passes, essentially without radial play and vertically to the abutment surface 9.

Die Klemmbacke 6 ist ein Blechteil, das an dem Bolzen 10 festgelegt ist. Für diese Festlegung hat die Klemmbacke 5 rückseitig vorspringende Betätigungslappen 13, die einander parallel sind und auf gleicher Höhe gegen­überliegen und gleichlange Schlitze 14 aufweisen. In diese Schlitze greifen die Enden eines Querstifts 15 des Bolzen­endes 12 derart ein und der Bolzen 10 ist in einem solchen Ausmaß axial verschieblich, daß die Klemmbacke 5 von der Widerlagerfläche 9 abgehoben werden kann, wenn eine ent­sprechend große Axialbeaufschlagung des Bolzens 10 erfolgt. Im übrigen hat die Klemmbacke 6 gemäß Fig. 1, 5 eine etwa U-förmige Querschnittsgestaltung und besitzt an ihrem oberen Ende 6′ eine das Fadeneinlegen erleichternde Abwinkelung.The jaw 6 is a sheet metal part which is fixed to the bolt 10. For this purpose, the clamping jaw 5 has actuating tabs 13 projecting from the rear, which are parallel to one another and lie opposite one another at the same height and have slots 14 of equal length. The ends of a cross pin 15 of the bolt end 12 engage in these slots and the bolt 10 is axially displaceable to such an extent that the clamping jaw 5 can be lifted off the abutment surface 9 if the bolt 10 is subjected to a correspondingly large axial load. 1, 5 has an approximately U-shaped cross-sectional configuration and has at its upper end 6 'a bend facilitating the thread insertion.

Der Zusammenbau des Bolzens 10 mit der Klemmbacke 6 erfolgt derart, daß der Querstift 15 nicht direkt auf die Klemmbacke 6 drückt. Diese wird vielmehr durch Federkraft am Widerlager 5 gehalten. Diese Federkraft wird von einer Steuerfeder 7 erzeugt. Im Inneren des Klemmengehäuses 11 ist eine Klemmfeder 16 den Bolzen 10 umgebend angeordnet, die sich einerseits an diesem Klemmengehäuse 11 und ande­rerseits an einem weiteren Querstift 42 des Bolzens 10 abstützt, mit dem der Bolzen 10 in Fig. 5 nach links ge­schoben am Gehäuse 11 gehalten wird. Die Klemmfeder 16 ist stärker, als die den Bolzen 10 zwischen dessen Quer­stift 15 und der Klemmbacke 6 umgebende Steuerfeder 7, die der Klemmfeder 16 entgegenwirkt und die Lage des Bolzens 10 nicht zu beeinflussen vermag. Sie bewirkt je­doch die Anlage der Klemmbacke 6 an der Widerlagerfläche 9 mit einer durch sie bestimmten Kraft. Diese Kraft ist durch eine Verstellung des Bolzens 10 genau dosierbar und mithin auch die Kraft, mit der die Klemmbacke 6 bei ver­stelltem Bolzen 10 auf den Faden 4 drückt.The bolt 10 is assembled with the jaw 6 in such a way that the cross pin 15 does not press directly on the jaw 6. Rather, this is held on the abutment 5 by spring force. This spring force is generated by a control spring 7. Inside the terminal housing 11, a clamping spring 16 is arranged surrounding the bolt 10, which is supported on the one hand on this terminal housing 11 and on the other hand on a further transverse pin 42 of the bolt 10, with which the bolt 10 is pushed to the left in FIG. 5 on the housing 11 becomes. The clamping spring 16 is stronger than the control spring 7 surrounding the bolt 10 between its transverse pin 15 and the clamping jaw 6, which counteracts the clamping spring 16 and the position of the Bolt 10 is not able to influence. However, it causes the clamping jaw 6 to bear against the abutment surface 9 with a force determined by it. This force can be precisely metered by adjusting the bolt 10 and consequently also the force with which the clamping jaw 6 presses on the thread 4 when the bolt 10 is adjusted.

Das gemäß Fig. 5 bei unverstelltem Bolzen 10 vorhandene Axialspiel zwischen der Klemmbacke 6 und dem Querstift 15 ge­stattet entsprechende Verlagerungen dieser Klemmbacke 6, z. B. beim Einfädeln, ohne dabei den Bolzen 10 verstellen zu müssen. Bei dickeren Fäden bleibt die Lage des Bolzens 10 ebenfalls unbeeinflußt.5 existing axial play between the jaw 6 and the cross pin 15 allows corresponding displacements of this jaw 6, z. B. when threading, without having to adjust the bolt 10. In the case of thicker threads, the position of the bolt 10 also remains unaffected.

Aus den Fig. 1 bis 5 ist noch ersichtlich, daß das Widerlager 5 einen Z-förmig ausgebildeten Vorsprung 19 hat, der in die rombusförmige Ausnehmung 38 des Abdeckblechs 27 vorspringt. Dieser Vorsprung 19 hat zum einen einen Kanten­abschnitt 19′, der vertikale Fadenauslenkungen nach oben begrenzt. Infolgedessen ist der Faden 4 in Verbindung mit dem Fadenleitelement 17 gemäß Fig. 2 gegen Höhenverlagerun­gen gesichert, so daß die Fadenklemmstelle vertikal prak­tisch unverschieblich ist, was zur Konstanz der Bremswirkung auf den Faden 4 beiträgt. Desweiteren hat der Vorsprung 19 aber auch eine Fadenleitkante 18, welche horizontal gerich­tete Fadenauslenkungen begrenzt, wobei der für den Faden 4 infolge der Bewegung der Wächternadel 2 erforderliche hori­zontale Spielraum nicht beschnitten ist.1 to 5 that the abutment 5 has a Z-shaped projection 19 which projects into the diamond-shaped recess 38 of the cover plate 27. This projection 19 has an edge portion 19 ', which limits the vertical thread deflections upwards. As a result, the thread 4 is secured in connection with the thread guide element 17 according to FIG. 2 against changes in height, so that the thread clamping point is practically immovable vertically, which contributes to the constancy of the braking effect on the thread 4. Furthermore, the projection 19 also has a thread guide edge 18 which limits horizontally directed thread deflections, the horizontal clearance required for the thread 4 due to the movement of the guard needle 2 not being cut.

Im übrigen ist der Vorsprung 19 so geformt, daß er im Bereich der Ausnehmung 38 mit dem Abdeckblech 27 den Ein­legeschlitz 20 so vervollständigt, daß der Faden 4 beim Einlegen in die Vorrichtung von oben vergleichsweise einfach der Fadenlaufstelle zugeführt wird, wobei der Bügel 40 oberhalb der Fadenklemme 3 in Verbindung mit der Formgebung des Gehäuses 11 für eine horizontale Erstreckung des Einlegeschlitzes 20 sorgt. Dabei ist die Wächternadel 2 insbesondere mit ihrem oberen Ende 21 so ausgebildet, daß sie beim Einlegen des Fadens 4 nicht beaufschlagt ist, bis diese in die durch den Abschnitt 19′ des Vor­sprungs 19 und das Fadenleitelement 17 bestimmte Faden­klemmstelle gelangt ist. Dabei sorgt das Fadenleitelement 17 auch dafür, daß der Faden 4 oberhalb des Bolzens 10 gehalten wird, so daß letzterer keinen Fadenabrieb er­zeugen kann.Otherwise, the projection 19 is shaped such that it completes the insertion slot 20 in the region of the recess 38 with the cover plate 27 so that the thread 4 is fed comparatively easily from above into the device when the thread is inserted, the bracket 40 above the Thread clamp 3 in connection with the shape the housing 11 ensures a horizontal extension of the insertion slot 20. The guard needle 2 is designed in particular with its upper end 21 so that it is not acted upon when inserting the thread 4 until it has reached the thread clamping point determined by the section 19 'of the projection 19 and the thread guide element 17. The thread guide 17 also ensures that the thread 4 is held above the bolt 10, so that the latter cannot produce thread abrasion.

Der Zusammenbau der Vorrichtung mit dem Gatter erfolgt über Befestigungsschrauben 43, die in Befestigungslappen 44 des Gehäuses 11 eingeschraubt werden und dabei dieses Ge­häuse 11 an einem U-förmigen vertikalen Gestellträger 45 des Gatters festlegen. In einem Gestellträger 45 ist eine Verstellvorrichtung 8 in Gestalt einer Stellstange vorhanden und alle Gestellstangen sind parallel beaufschlagbar, so daß eine entsprechende gemeinsame Beaufschlagung aller Fadenklemmen möglich ist. An der Verstellvorrichtung 8 ist für jede Fadenklemme 3 ein Steuerblech 46 befestigt, das eine Steuerfläche 47 aufweist. Mit dieser Steuerfläche 47 kann der Bolzen 10 bei Höhenverstellung der Verstellvor­richtung bzw. Stange 8 entsprechend horizontal verschoben werden und infolgedessen die Klemmfeder 16 zusammendrücken und die Steuerfeder 7 entlasten.The assembly of the device with the gate takes place via fastening screws 43 which are screwed into fastening tabs 44 of the housing 11 and thereby fix this housing 11 to a U-shaped vertical frame carrier 45 of the gate. In a rack support 45 there is an adjusting device 8 in the form of an adjusting rod and all rack rods can be acted upon in parallel, so that a corresponding joint action on all thread clamps is possible. A control plate 46, which has a control surface 47, is fastened to the adjusting device 8 for each thread clamp 3. With this control surface 47, the bolt 10 can be correspondingly horizontally displaced when the height of the adjusting device or rod 8 is adjusted, and as a result compress the clamping spring 16 and relieve the control spring 7.

Fig. 7a zeigt die Klemmstellung der Fadenklemme 3, in der also die Klemmbacke 6 unter Einwirkung der Federn 7, 16 auf den Faden 4 drückt und diesen gespannt hält, so daß er nicht weiter durchrutschen kann. Fig. 7b zeigt eine Auslenkung des Bolzens 10, bei der die Klemmfeder 16 zum Teil zusammengedrückt ist und die Feder 7 der Verstellung des Bolzens 10 entsprechend entlastet wurde. Eine solche Stellung erreicht der Bolzen 10 durch die Steuerung mit der Verstellvorrichtung 8 während des Anlaufens der alle Fäden 4 abziehenden Aufwickelmaschine bereits während der ersten Laufmeter der Fadenschar. Fig. 7b zeigt den Zustand der Fadenbremse 3 kurz vor dem Abheben der Klemm­backe 6 vom Widerlager 5. Eine Fadenwächterung erfolgt von dem Augenblick an, in dem ein Faden 4 eine Faden­spannung erreicht, aufgrund der die Ansprechschwelle des Fadenwächters erreicht wird. Fig. 7c zeigt die vom Widerlager 5 abgehobene Klemmbacke 6, wobei die Verschie­bung durch Angriff des Querstifts 15 an den Betätigungs­lappen 13 erreicht wird.Fig. 7a shows the clamping position of the thread clamp 3, in which the clamping jaw 6 presses under the action of the springs 7, 16 on the thread 4 and keeps it taut so that it cannot slip any further. 7b shows a deflection of the bolt 10, in which the clamping spring 16 is partially compressed and the spring 7 has been relieved of the adjustment of the bolt 10 accordingly. The bolt 10 achieves such a position by the control with the adjusting device 8 during the start of all Threads 4 pulling winding machine already during the first running meter of the thread coulter. 7b shows the state of the thread brake 3 shortly before the clamping jaw 6 is lifted off from the abutment 5. Thread monitoring takes place from the moment when a thread 4 reaches a thread tension on the basis of which the response threshold of the thread monitor is reached. 7c shows the clamping jaw 6 lifted off the abutment 5, the displacement being achieved by the cross pin 15 engaging the actuating tab 13.
