Definitions

  • the invention relates to a central adjustment device for thread clamps of bobbin creels, with vertically displaceable adjusting rods, each associated with a row of bobbins, on which a control ramp is formed for each thread clamp, with which a spring-loaded bolt that controls the thread clamp in an open or in a clamping position can be adjusted and with a vertically driven adjusting lever assigned to each adjusting rod, which engages the adjusting rod and is able to move it into a first position corresponding to the open position of the thread clamp, from which the adjusting rod is adjustable into a second position corresponding to the clamping position of the thread clamp.

  • the known central adjustment device is designed so that each gate side is assigned an electrically controlled pneumatic cylinder, which is arranged above the winding units and at the end of the gate side.

Abstract

A central actuator for thread clamps belonging to a creel of reels has, for each row of reels, positioning rods (50) capable of vertical displacement on which, for each thread clamp (14), a control ramp (49) is formed to shift a spring-loaded bolt (31) which sets the clamp in an open or a clamping position. With each positioning rod is associated a vertically driven shifting lever (51) which acts on the rod to allow it to rest in a first position corresponding to the clamp open setting from which it can be shifted into a second position corresponding to the clamping position. The shifting lever acts on an adjusting part (60) which can be smoothly adjusted and fixed vertically on the rod while a stop (57) can be similarly set on the rod so that the spring-loaded bolt rests on the ramp in a position to support the clamp in its second or clamping position.

Description

Die Erfindung bezieht sich auf eine Zentralverstelleinrichtung für Fadenklemmen von Spulengattern, mit vertikal verschieblichen, jeweils einer Spulenreihe zugeordneten Stellstangen, an denen für jede Fadenklemme eine Steuerrampe ausgebildet ist, mit der ein federbeaufschlagter, die Fadenklemme in eine Offen- oder in eine Klemmstellung steuernder Bolzen verstellbar ist, und mit einem jeder Stellstange zugeordneten vertikal angetriebenen Verstellhebel, der an der Stellstange angreift und diese in eine der Offenstellung der Fadenklemme entsprechende erste Stellung zu bewegen vermag, aus der die Stellstange in eine der Klemmstellung der Fadenklemme entsprechende zweite Stellung verstellbar ist.The invention relates to a central adjustment device for thread clamps of bobbin creels, with vertically displaceable adjusting rods, each associated with a row of bobbins, on which a control ramp is formed for each thread clamp, with which a spring-loaded bolt that controls the thread clamp in an open or in a clamping position can be adjusted and with a vertically driven adjusting lever assigned to each adjusting rod, which engages the adjusting rod and is able to move it into a first position corresponding to the open position of the thread clamp, from which the adjusting rod is adjustable into a second position corresponding to the clamping position of the thread clamp.

Eine Zentralverstelleinrichtung mit den vorgenannten Merkmalen ist beispielsweise aus der DE 37 34 518 bekannt. Sie kommt bei Spulengattern zum Einsatz, die eine Vielzahl von Spulstellen aufweisen. Jede Spulstelle trägt eine Spule, deren Faden über Kopf abgezogen wird. Der Faden durchläuft eine Fadenklemme und wird um eine Fadenwächternadel umgelenkt und von einer Wickelmaschine auf deren Wickelbaum aufgewickelt. Das Aufwickeln erfolgt mit hohen Wickelgeschwindigkeiten, so daß die Luftreibung des Fadens zumindest einen wesentlichen Teil der Fadenzugkraft ausmacht, welche die Wickelmaschine aufzubringen hat. Im Stillstandsfall, auch im Fall einer plötzlichen Wickelunterbrechung wegen Fadenbruchs, werden alle Fadenklemmen des Spulengatters aktiviert, um alle Fäden der gesamten Fadenschar stramm zu halten. Geschähe dies nicht, würden sich die Fäden verheddern. Ein störungsfreier Wiederanlauf wäre dann nicht gewährleistet.A central adjustment device with the aforementioned features is known for example from DE 37 34 518. It is used for creels that have a large number of winding positions. Each winding unit carries a bobbin, the thread of which is drawn off overhead. The thread passes through a thread clamp and is deflected around a thread monitor needle and wound onto a winding machine by a winding machine. The winding takes place at high winding speeds, so that the air friction of the thread makes up at least a substantial part of the thread tensile force which the winding machine has to apply. In the event of a standstill, also in the event of a sudden interruption of the winding due to thread breakage, all the thread clamps of the bobbin creel are activated in order to keep all the threads of the entire thread set taut. Do this not, the threads would get tangled. A trouble-free restart would then not be guaranteed.

Es ist erforderlich, daß alle Fäden der gesamten Fadenschar von den Fadenklemmen gleichzeitig und in gleichem Maße geklemmt werden. Darüber hinaus ist es erforderlich, daß alle Fadenklemmen in gleichem Maße geöffnet sind, um einen reibungsfreien bzw. um einen störungsfreien Fadendurchlauf zu gewährleisten. Es ist also erforderlich, daß alle Klemmbacken der Fadenklemmen zu den zugehörigen Widerlagern gleichmäßig großen Abstand aufweisen. Das trägt auch dazu bei, daß sich wenig Abrieb und Flusenflug in den Fadenklemmen absetzen kann, was zu losen Fäden im Klemmfall führen würde.It is necessary that all threads of the entire thread family are clamped by the thread clamps simultaneously and to the same extent. In addition, it is necessary that all thread clamps are opened to the same extent in order to ensure a smooth or trouble-free thread passage. It is therefore necessary that all the jaws of the thread clamps have a uniformly large distance from the associated abutments. This also contributes to the fact that little abrasion and fluff can settle in the thread clamps, which would lead to loose threads in the event of a clamp.

Die bekannte Zentralverstelleinrichtung ist so ausgebildet, daß jeder Gatterseite ein elektrisch gesteuerter Pneumatikzylinder zugeordnet ist, der oberhalb der Spulstellen und am Ende der Gatterseite angeordnet ist. An dem Pneumatikzylinder sind Stangen angelenkt, die waagerecht oberhalb der Spulstellen geführt sind. Diese Stangen sind sehr lang und bestehen aus mehreren Teilstücken. Die zylinderbeaufschlagten waagerechten Stangen sind antriebsmäßig mit den Verstellhebeln verbunden. Durch die Vielzahl der Bauteile und die grossen Längen üblicher Gatter sind entsprechend große Toleranzen vorhanden, die eine ideale Einstellung der Zentralverstelleinrichtung nicht zulassen. Es ist allgemein bekannt, über eine Hubveränderung an den Pneumatikzylindern die Klemmkräfte der Fadenklemmen gesamthaft zu verändern. Durch die vorgenannten Toleranzen ist jedoch die infolgedessen vorhandene Ungleichmäßigkeit der Klemmkräfte nicht auszugleichen. Auch eine Vergleichmäßigung der Öffnung der Fadenklemmen in deren Offenstellung ist nicht gesamthaft möglich.The known central adjustment device is designed so that each gate side is assigned an electrically controlled pneumatic cylinder, which is arranged above the winding units and at the end of the gate side. Rods are articulated to the pneumatic cylinder, which are guided horizontally above the winding units. These rods are very long and consist of several sections. The horizontal rods, which are acted upon by cylinders, are connected to the adjusting levers in terms of drive. Due to the large number of components and the large lengths of conventional gates, there are correspondingly large tolerances that do not allow ideal adjustment of the central adjustment device. It is generally known to change the overall clamping forces of the thread clamps by changing the stroke of the pneumatic cylinders. However, due to the aforementioned tolerances, the consequent nonuniformity of the clamping forces cannot be compensated for. Even a uniformization of the opening of the thread clamps in their open position is not possible overall.

Ferner sind Fadenklemmen allgemein bekannt, deren Klemmkraft in drei Stufen grob einstellbar ist. In diesem Fall ist zwar eine individuelle Beeinflussung der Fadenklemmen möglich, jedoch muß wegen der Vielzahl der Fadenklemmen ein großer Verstellaufwand betrieben werden, so daß diese Einstellmöglichkeit letztlich nicht genutzt wird.Furthermore, thread clamps are generally known, the clamping force of which can be roughly adjusted in three stages. In this case, it is possible to influence the thread clamps individually, but because of the large number of thread clamps, a great deal of adjustment work has to be carried out, so that this setting option is ultimately not used.

Dem Bekannten gegenüber liegt der Erfindung die Aufgabe zugrunde, eine Zentralverstelleinrichtung mit den eingangs genannten Merkmalen so zu verbessern, daß eine gesamthafte Einstellung aller Fadenklemmen erleichtert wird, ohne dabei an allen Fadenklemmen jeweils einzeln Einstellungen vornehmen zu müssen.Compared to the known, the object of the invention is to improve a central adjustment device with the features mentioned at the outset in such a way that an overall setting of all thread clamps is facilitated without having to make individual settings on all thread clamps.

Diese Aufgabe wird dadurch gelöst, daß der Verstellhebel an einem Einstellteil angreift, das an der Stellstange vertikal stufenlos einstellbar befestigt ist und/oder daß die zweite, der Klemmstellung der Fadenklemme entsprechende Stellung der Stellstange von einem diese abstützenden Anschlag bestimmt ist, dessen Vertikalstellung stufenlos bis zur Abstützung des Bolzens auf der Steuerrampe einstellbar ist.This object is achieved in that the adjusting lever engages on an adjusting part which is fastened to the adjusting rod in a vertically steplessly adjustable manner and / or in that the second position of the adjusting rod corresponding to the clamping position of the thread clamp is determined by a stop which supports it, the vertical position of which is stepless until adjustable to support the bolt on the control ramp.

Für die Erfindung ist von Bedeutung, daß der vertikal angetriebene Verstellhebel gesamthaft beeinflußt wird. Für diese Beeinflussung ist zum einen das Einstellteil vorgesehen, durch dessen stufenlose vertikale Einstellung erreicht werden kann, daß die Stellstange höher oder tiefer positioniert wird. Dementsprechend werden auch sämtliche Schrägflächen einer Stellstange höher oder tiefer positioniert, so daß alle Stellungen der Fadenklemme beeinflußt werden, soweit sie durch diese Schrägflächen beeinflußt werden können. Es ergibt sich eine spulenreihenweise Justierbarkeit, durch die sämtliche Toleranzen der Zentralverstelleinrichtung zwischen diesem Einstellteil bis zu einem Pneumatikzylinder als beispielsweisem Antriebselement ausgeschaltet werden können. Infolge der stufenlosen vertikalen Einstellung zwischen dem Einstellteil und der Stellstange kann der senkrechte Hub der Stellstange so verändert werden, daß der freie Durchgang des Fadens zwischen einer Klemmbacke der Fadenklemme und einem Widerlager dieser Klemmbacke einstellbar gleich gehalten wird.It is important for the invention that the vertically driven adjusting lever is influenced as a whole. For this influencing, on the one hand, the adjusting part is provided, through the stepless vertical adjustment of which it can be achieved that the adjusting rod is positioned higher or lower. Accordingly, all inclined surfaces of an actuating rod are positioned higher or lower, so that all positions of the thread clamp are influenced insofar as they can be influenced by these inclined surfaces. The result is an adjustability in rows of coils, by means of which all tolerances of the central adjustment device between this adjusting part and a pneumatic cylinder as an example drive element can be switched off. Due to the stepless vertical adjustment between the adjusting part and the adjusting rod, the vertical stroke of the adjusting rod can be changed so that the free passage of the thread between a jaw of the thread clamp and an abutment of this jaw is kept adjustable the same.

Die Zentralverstelleinrichtung kann zum anderen dahingehend ausgebildet werden, daß die zweite, der Klemmstellung der Fadenklemme entsprechende Stellung der Stellstange von einem diese abstützenden Anschlag bestimmt ist, dessen Vertikalstellung stufenlos bis zur Abstützung des Bolzens auf der Steuerrampe einstellbar ist. Infolge der Einstellbarkeit der Vertikalstellung des abstützenden Anschlags hat die Stellstange eine von der Einstellmöglichkeit über das Einstellteil unabhängige Einstellmöglichkeit. Die Stellstange kann also bezüglich der Klemmstellungen ihrer Fadenklemmen unabhängig davon stufenlos eingestellt werden, wie die Offenstellung über das Einstellteil eingestellt wurde. Durch die stufenlose Verstellung des Anschlags, bedarfsweise bis in den Bereich hinein, in dem sich der Bolzen auf der Steuerrampe abstützt, kann eine genaue materialbezogene Klemmkraft eingestellt werden.On the other hand, the central adjustment device can be designed in such a way that the second position of the actuating rod, which corresponds to the clamping position of the thread clamp, is determined by a stop supporting it, the vertical position of which can be adjusted continuously until the bolt is supported on the control ramp. Due to the adjustability of the In the vertical position of the supporting stop, the adjusting rod has an adjustment option that is independent of the adjustment option via the adjustment part. The adjusting rod can thus be continuously adjusted with regard to the clamping positions of its thread clamps, regardless of how the open position was set via the setting part. Through the infinitely variable adjustment of the stop, if necessary, into the area in which the bolt is supported on the control ramp, an exact material-related clamping force can be set.

Es ist insbesondere vorteilhaft, die Zentralverstelleinrichtung so auszubilden, daß das Einstellteil zwischen dem oberen Ende der Stellstange und dem Verstellhebel angeordnet ist. Es ergibt sich eine kompakte Bauform am oberen Ende der Stellstange im Hinblick auf die von dem Pneumatikzylinder angetriebenen Stangen und Verstellhebel.It is particularly advantageous to design the central adjustment device such that the adjustment part is arranged between the upper end of the adjustment rod and the adjustment lever. The result is a compact design at the upper end of the adjusting rod with regard to the rods and adjusting levers driven by the pneumatic cylinder.

In konstruktiv einfacher Weise sind das Einstellteil und die Stellstange miteinander verschraubt. Die Verschraubung kann leicht gelöst werden, um die Stellstange in eine relativ andere Lage zum Einstellteil zu bringen.The adjusting part and the adjusting rod are screwed together in a structurally simple manner. The screw connection can be easily loosened in order to bring the adjusting rod to the adjustment part in a relatively different position.

Will man eine stufenlose Verstellung erreichen, so kann die Zentralverstelleinrichtung so ausgebildet werden, daß das Einstellteil und/oder die Stellstange Langlöcher aufweisen, deren Länge dem vertikalen Einstellbereich entspricht.If you want to achieve a continuous adjustment, the central adjustment device can be designed so that the adjusting part and / or the adjusting rod have elongated holes, the length of which corresponds to the vertical adjustment range.

Es ist möglich, die für eine derartige Einstellung zweckmäßigen Einstellelemente einzusetzen. Sofern nur geringe Einstellhübe nötig sind, ist es vorteilhaft, wenn das Einstellteil und die Stellstange über einen Einstellexzenter miteinander verbunden sind. In diesem Fall ist es nicht nötig, das Einstellteil und die Stellstange über eine Verschraubung zu betätigen, wenn der Einstellexzenter selbsthemmend ausgebildet ist.It is possible to use the appropriate setting elements for such an adjustment. If only small adjustment strokes are necessary, it is advantageous if the adjustment part and the adjustment rod are connected to one another via an adjustment eccentric. In this case, it is not necessary to operate the adjusting part and the adjusting rod by means of a screw connection if the adjusting eccentric is designed to be self-locking.

Es muß dafür gesorgt werden, daß die beiden Einstellmöglichkeiten an der Stellstange unabhängig voneinander möglich sind. Zu diesem Zweck kann die Zentralverstelleinrichtung so ausgebildet werden, daß das Einstellteil lose auf dem vertikal angetriebenen Verstellhebel aufliegt, der aus dem vertikalen Bewegungsbereich der Stellstange entfernbar ist und die Stellstange aus ihrer zweiten Stellung in die erste anheben kann. Die Lose zwischen dem Einstellteil und dem vertikal angetriebenen Verstellhebel ermöglicht es, die Stellstange einschließlich des Einstellteils für die Klemmstellung der Fadenklemme zu Positionieren. Der Antrieb des Verstellhebels ist so ausgebildet, daß die Stellstange aus dieser Stellung mit dem Verstellhebel unter Beseitigung der Lose anzuheben ist.It must be ensured that the two setting options on the adjusting rod are possible independently of one another. For this purpose, the central adjustment device can be formed so that the adjusting part lies loosely on the vertically driven adjusting lever, which can be removed from the vertical range of movement of the adjusting rod and can lift the adjusting rod from its second position into the first. The slack between the adjusting part and the vertically driven adjusting lever makes it possible to position the adjusting rod including the adjusting part for the clamping position of the thread clamp. The drive of the adjusting lever is designed so that the adjusting rod can be lifted from this position with the adjusting lever while eliminating the slack.

Die Zentralverstelleinrichtung kann so ausgebildet werden, daß der vertikal angetriebene Verstellhebel das Einstellteil freizugeben vermag, wodurch die Stellstange infolge ihres Eigengewichts in ihre zweite, der Klemmstellung der Fadenklemme entsprechende Stellung gelangt. Es ist infolgedessen nicht nötig, für die Stellstange einen Antrieb vorzusehen, mit dem sie in die der Klemmstellung der Fadenklemme entsprechende Stellung gelangt.The central adjustment device can be designed in such a way that the vertically driven adjustment lever is able to release the adjustment part, as a result of which the adjusting rod, due to its own weight, reaches its second position, which corresponds to the clamping position of the thread clamp. As a result, it is not necessary to provide a drive for the adjusting rod with which it arrives in the position corresponding to the clamping position of the thread clamp.

Der die Stellstange bzw. dessen Einstellteil antreibende Stellhebel hat eine entsprechende Betätigungskraft zu übertragen, die üblicherweise von einem Pneumatikzylinder als üblichem Antriebsteil der Zentralverstelleinrichtung ausgeübt wird. Die Weiterleitung der Betätigungskraft erfolgt oberhalb der Spulstellen horizontal, so daß eine Bewegungsumlenkung aus der Horizontalen in die Vertikale notwendig ist. Die Zentralverstelleinrichtung wird daher so ausgebildet, daß der vertikal angetriebene Verstellhebel ein zweiarmiger Schwenkhebel ist, dessen einer Arm von einem Antrieb beaufschlagbar ist und auf dessen anderem Arm das Einstellteil lose aufliegt.The actuating lever which drives the actuating rod or its adjusting part has to transmit a corresponding actuating force which is usually exerted by a pneumatic cylinder as the usual drive part of the central adjusting device. The transmission of the actuating force takes place horizontally above the winding units, so that a deflection of movement from the horizontal into the vertical is necessary. The central adjustment device is therefore designed such that the vertically driven adjusting lever is a two-armed pivoting lever, one arm of which can be acted upon by a drive and the adjusting part rests loosely on the other arm.

Das in den Fig.1,2 dargestellte Spulengatter 10 ist ein sogenanntes V-Gatter, von dessen beiden Gatterseiten 10' Fäden F einer Wickelvorrichtung zulaufen, nämlich einer Zettelmaschine 11, von der die Fadenschar der Fäden F auf einen Wickelbaum 21 aufgewickelt wird. Der Wickelbaum 21 besitzt Wickelscheiben 21', zwischen denen eine Anpreßwalze 22 auf den sich beim Wickeln ständig im Durchmesser vergrößernden Wickel drückt. Der Wickelvorgang wird von einem Steuerpult 23 der Wickelvorrichtung gesteuert, von wo aus auch eine Abschaltung erfolgen kann, falls ein Bruch eines Fadens F vorliegt.The coil creel 10 shown in FIGS. 1, 2 is a so-called V-creel, from the two creel sides 10 'of which threads F run towards a winding device, namely a warping machine 11, from which the group of threads of threads F is wound onto a winding tree 21. The winding tree 21 has winding disks 21 ', between which a pressure roller 22 presses on the winding which is constantly increasing in diameter during winding. The winding process is controlled by a control panel 23 of the winding device, from where it can also be switched off if a thread F is broken.

Das Spulengatter 10 hat eine größere Anzahl von Gatterfeldern 20, in denen Spulen 24 in herkömmlicher Weise zeilen- und spaltenförmig angeordnet sind. Zur Aufnahme der Spulen 24 in jedem Spulenfeld 20 zeigt Fig.2 schematisch mit strichpunktierten Drehkreisen veranschaulichte Drehgatter 25, die vom Innenraum 26 des Spulengatters 10 aus bestückt werden können, während auf den Außenseiten der Gatterseiten 10' die Fäden F abgezogen werden.The coil gate 10 has a larger number of gate fields 20, in which coils 24 are arranged in rows and columns in a conventional manner. To accommodate the bobbins 24 in each bobbin field 20, FIG. 2 schematically shows rotary gates 25 illustrated with dash-dotted rotating circles, which can be equipped from the interior 26 of the bobbin gate 10, while the threads F are drawn off on the outer sides of the gate sides 10 '.

Zur Aufnahme der Spulen 24 im Spulengatter 10 dienen Spulstellen 12' mit nicht dargestellten Spulendornen, auf die die Spulen 24 aufgesteckt werden. Von diesen Spulen 24 wird der Faden F über Kopf abgezogen, durchläuft eine nicht dargestellte Fadenführungseinrichtung und wird in Richtung zur Wickelvorrichtung 11 umgelenkt. Damit alle Fäden F der Gesamtfadenschar F-F im Falle eines Stillstands der Wickelvorrichtung 11 in gleicher Weise geordnet zum Stillstand kommen, hat jede Fadenführungsvorrichtung eine Fadenklemme 14, die an einer Gatterstrebe 26 in nicht dargestellter Weise angebracht ist. Die Gatterstrebe 26 ist ein Bestandteil des im übrigen nicht näher dargestellten Gattergestells, von dessen Spulendornen auch die Spulen 24 getragen sind. Die Fadenklemme 14 hat ein rohrstückartiges Gehäuse 27 mit einem außenliegenden Widerlager 29. Dieses wirkt mit einer in der Darstellungsebene verstellbaren Klemmbacke 30 zusammen. Zwischen der Klemmbacke 30 und dem Widerlager 29 läuft der Faden F senkrecht zur Darstellungsebene. Der Fadenverlauf ist idealerweise so, daß der Faden weder die Klemmbacke 30, noch das Widerlager 29 berührt. Für eine derartige Führung des Fadens sorgen beispielsweise im Raum zwischen der Fadenklemme 14 und der zugehörigen Spule angeordnete Vorumschlingungsstangen, die an sich bekannt und daher hier nicht dargestellt sind.To accommodate the coils 24 in the creel 10 are used winding stations 12 'with coil spindles, not shown, onto which the coils 24 are attached. The thread F is drawn off from these bobbins 24, passes through a thread guide device (not shown) and is deflected in the direction of the winding device 11. So that all threads F of the total thread set FF come to an orderly standstill in the same way when the winding device 11 is at a standstill, each thread guide device has a thread clamp 14 which is attached to a gate strut 26 in a manner not shown. The gate strut 26 is a component of the gate frame, which is not shown in any more detail, from the coil mandrels of which the coils 24 are also carried. The thread clamp 14 has a tubular housing 27 with an external abutment 29. This interacts with a clamping jaw 30 which is adjustable in the plane of the illustration. Between the jaw 30 and the abutment 29, the thread F runs perpendicular to the plane of representation. The thread course is ideally such that the thread does not touch either the jaw 30 or the abutment 29. Such a guiding of the thread provides, for example, pre-wrapping rods arranged in the space between the thread clamp 14 and the associated bobbin, which are known per se and are therefore not shown here.

Die Klemmbacke 30 ist von einem Bolzen 31 gehalten, der im Gehäuse 27 derart geführt ist, daß sich die Klemmbacke 30 lediglich entsprechend dieser Führung bewegen kann. Hierzu ist der Bolzen 31 in den aus den Fig.3,4 ersichtlichen Bohrungen in den Richtungen seiner Längsachse geführt. Das klemmbackenseitige Ende 40 des Bolzens 31 hat einen zur Darstellungsebene vertikalen Führungsstift 41, dessen beide Enden in Schlitzen 42 geführt sind, die sich in bolzenparallelen Haltelappen 43 der Klemmbacke 30 befinden. Der Boden 44 der Klemmbacke hat ein Loch, der vom Bolzen 31 durchsetzt ist, so daß er stets senkrecht zum Bolzen 31 angeordnet ist. Zwischen dem Boden 44 und einem Abstützstift 46 stützt sich eine Druckfeder 45 ab, die die Klemmbacke 30 in ihre Klemmstellung zu drücken sucht. Des weiteren ist eine Druckfeder 47 vorgesehen, die sich mit einem Ende am Gehäuse 27 und mit dem anderen Ende am Kragen 48 des Bolzens 31 abstützt, so daß sie die Klemmbacke 30 in die Klemmstellung zu drücken sucht.The jaw 30 is held by a bolt 31 which is guided in the housing 27 such that the jaw 30 can only move in accordance with this guide. For this purpose, the bolt 31 is guided in the bores shown in FIGS. 3, 4 in the directions of its longitudinal axis. The jaw-side end 40 of the bolt 31 has a guide pin 41 which is vertical to the plane of the illustration and whose two ends are guided in slots 42 which are located in retaining lugs 43 of the jaw 30 parallel to the bolt. The bottom 44 of the jaw has a hole which is penetrated by the bolt 31 so that it is always arranged perpendicular to the bolt 31. Between the bottom 44 and a support pin 46, a compression spring 45 is supported, which tries to press the jaw 30 into its clamping position. Furthermore, a compression spring 47 is provided which is supported at one end on the housing 27 and at the other end on the collar 48 of the bolt 31, so that it tries to press the clamping jaw 30 into the clamping position.

Die Steuerung des Bolzens 31 in die eine Stellung, nämlich in Fig.3 dargestellte Offenstellung der Fadenklemme 14, oder in die andere Stellung, nämlich die in Fig.4 dargestellte Klemmstellung der Fadenklemme 14, erfolgt mit einer Steuerrampe 49. Diese Steuerrampe 49 ist ein an einer Stellstange 50 befestigtes Blechteil. Befindet sich dieses in der in Fig. 3 dargestellten Hochstellung, wird der Bolzen 31 entgegen der Kraft der Feder 47 nach rechts verschoben. Der durch die Steuerrampe 49 zu erzielende Hub ist so groß, daß der volle Durchlaufspalt zwischen der Klemmbacke 30 und dem Widerlager 29 freigegeben wird. Das kann auch bereits dann der Fall sein, wenn der Bolzen 31 noch nicht die in Fig.3 dargestellte Stellung erreicht hat, sondern sich noch auf der Steuerrampe 49 abstützt. Befindet sich die Stellstange 50 hingegen in ihrer Tiefstellung gemäß Fig.4, so vermag die Feder 47 den Bolzen 31 entgegen der Wirkung der Feder 45 nach links zu verschieben, so daß die Klemme 14 schließt.The control of the bolt 31 in one position, namely the open position of the thread clamp 14 shown in FIG. 3, or in the other position, namely the clamped position of the thread clamp 14 shown in FIG. 4, takes place with a control ramp 49. This control ramp 49 is a sheet metal part fastened to an adjusting rod 50. If this is in the high position shown in FIG. 3, the bolt 31 is displaced to the right against the force of the spring 47. The stroke to be achieved by the control ramp 49 is so large that the full passage gap between the clamping jaw 30 and the abutment 29 is released. This can already be the case be when the bolt 31 has not yet reached the position shown in Figure 3, but is still supported on the control ramp 49. If, on the other hand, the actuating rod 50 is in its low position according to FIG. 4, the spring 47 is able to move the bolt 31 to the left against the action of the spring 45, so that the clamp 14 closes.

Beim Lösen der Fadenklemme 14 wird der Auflagedruck der Klemmbacke 30 auf das Widerlager 29 in dem Maß verringert, wie sich die Feder 45 entspannen kann. Der Auflagedruck der Klemmbacke 30 auf dem Faden wird demgemäß nicht sprunghaft von maximalen Klemmdruck auf Null verringert, sondern entsprechend der stetigen Verringerung des von Feder 45 verursachten Anpreßdrucks.When the thread clamp 14 is released, the contact pressure of the clamping jaw 30 on the abutment 29 is reduced to the extent that the spring 45 can relax. The contact pressure of the clamping jaw 30 on the thread is accordingly not abruptly reduced from the maximum clamping pressure to zero, but rather in accordance with the steady decrease in the contact pressure caused by the spring 45.

Die Stellstange 50 wird von einem Verstellhebel 51 hochgehalten, der als zweiarmiger Winkelhebel ausgebildet ist. Er ist von einer Stange 52 angetrieben, die am Winkelarm 53 angelenkt ist und horizontal verstellt wird, beispielsweise infolge Beaufschlagung durch einen Pneumatikzylinder 54, der über die Stange 52 auf den Hebelarm 53 einwirkt. Ein Verschwenken um den gattergestellfesten Drehpunkt 55 im Gegenuhrzeigersinn bewirkt ein Absenken des Hebelarms 56 und damit den Übergang der Stellstange 50 aus der in Fig.3 dargestellten Stellung in die in Fig.4 dargestellte Tiefstellung. Hierzu wird der Verstellhebel 51 schnell weggeklappt, so daß die Stange 50 nach unten fällt. Ihr Fall wird durch einen an der Gatterstrebe 26 einstellbar befestigten Anschlag 57 begrenzt, der aus schalldämmendem Werkstoff besteht. Dessen Befestigung erfolgt beispielsweise mittels einer Befestigungsschraube 58. Außerdem ist der Anschlag 57 mit einem Langloch 59 versehen, so daß er im Umfang dieses Langlochs nach oben und nach unten verstellt werden kann. Der Anschlag 57 wird beispielsweise völlig nach unten verstellt, wenn der Bolzen 31 noch in nicht dargestellter Weise im Schrägbereich der Steuerrampe 49 abgestützt ist und gewährleistet werden soll, daß die Fadenklemme 14 mit voller Kraft der Feder 45 klemmt. Andererseits kann es durchaus sein, daß mit dem Anschlag 57 eine Stellung der Stellstange 50 eingestellt wird, bei der sich der Bolzen 31 auf der Schräge der Steuerrampe 49 abstützt. Damit kann eine genaue materialbezogene Klemmkraft stufenlos eingestellt werden. Die Einstellung erfolgt in demjenigen Teil der Steuerrampe 49, bezüglich dessen der Bolzen 31 innerhalb des Schlitzes 42 frei beweglich ist, ohne daß die Fadenklemme 14 öffnet.The adjusting rod 50 is held up by an adjusting lever 51, which is designed as a two-armed angle lever. It is driven by a rod 52 which is articulated on the angle arm 53 and is adjusted horizontally, for example as a result of being acted upon by a pneumatic cylinder 54 which acts on the lever arm 53 via the rod 52. A pivoting about the pivot point fixed to the frame frame 55 in a counterclockwise direction causes the lever arm 56 to lower and thus the transition of the adjusting rod 50 from the position shown in FIG. 3 to the low position shown in FIG. For this purpose, the adjusting lever 51 is quickly folded away so that the rod 50 falls down. Your case is limited by a stop 57 which is adjustably fastened to the gate strut 26 and which is made of sound-absorbing material. Its attachment is carried out, for example, by means of a fastening screw 58. In addition, the stop 57 is provided with an elongated hole 59 so that it can be adjusted up and down in the circumference of this elongated hole. The stop 57 is adjusted completely downward, for example, when the bolt 31 is still supported in a manner not shown in the inclined area of the control ramp 49 and it is to be ensured that the thread clamp 14 clamps with full force of the spring 45. On the other hand, it may well be that a position of the actuating rod 50 is set with the stop 57, in which the bolt 31 is supported on the slope of the control ramp 49. With that a exact material-related clamping force can be set continuously. The setting is made in that part of the control ramp 49 with respect to which the bolt 31 is freely movable within the slot 42 without the thread clamp 14 opening.

Andererseits muß auch die Hochstellung der Stange 50 eingestellt werden können, und zwar zweckmäßigerweise unabhängig von ihrer Tiefstellung. Hierzu ist die Stellstange 50 mit einem Einstellteil 60 versehen, nämlich mit einem Winkel, dessen einer Winkelschenkel 60' etwa horizontal angeordnet ist und auf einem Tragstift 61 des Winkelarms 56 des Verstellhebels 51 lose aufliegt. Der andere Winkelarm 60'' ist am oberen Ende 50' der Stellstange 50 befestigt und ist hierzu mit einem Langloch 62 versehen, so daß er vertikal einstellbar ist. Es kann infolgedessen erreicht werden, daß das obere Ende 50' der Stellstange 50 soweit wie möglich nach oben verschoben am Winkelarm 60' befestigt wird. Das ist beispielsweise ratsam, wenn die in Fig.3 dargestellte volle Offenstellung der Fadenklemme 14 erreicht werden soll, der Bolzen 31 jedoch noch in nicht dargestellter Weise auf der Schrägfläche der Steuerrampe 49 abgestützt ist.On the other hand, it must also be possible to adjust the up position of the rod 50, expediently regardless of its down position. For this purpose, the adjusting rod 50 is provided with an adjusting part 60, namely with an angle, the one angle leg 60 'of which is arranged approximately horizontally and lies loosely on a support pin 61 of the angle arm 56 of the adjusting lever 51. The other angle arm 60 ″ is fastened to the upper end 50 ′ of the adjusting rod 50 and is provided with an elongated hole 62 so that it can be adjusted vertically. As a result, it can be achieved that the upper end 50 'of the actuating rod 50 is attached as far as possible upwards to the angle arm 60'. This is advisable, for example, if the full open position of the thread clamp 14 shown in FIG. 3 is to be reached, but the bolt 31 is still supported on the inclined surface of the control ramp 49 in a manner not shown.
