Description

Gegenstand der Erfindung ist eine Aktivierungsvorrichtung zur weg- und zeitabhängigen Bewegung einer Fadenschneid-und Anstickeinheit und dergleichen.The invention relates to an activation device for the path and time-dependent movement of a thread cutting and embroidery unit and the like.

Beim Nähen und insbesondere aber beim Sticken auf Haushaltnähmaschinen werden durch die Mustergestaltung ein häufiger Abschluss einer Naht und ein Neuanfang einer Naht oder eines Stickmusters notwendig. Dabei ist es wichtig, dass einerseits das Beenden einer Naht und Abschneiden der Fäden und die Lage der Enden der abgeschnittenen Fäden optimal ausgeführt ist und dass beim Annähen oder Ansticken einer neuen Naht auch die ersten Stiche mit satten Knoten erfolgen. Ein mögliches Verfahren, diese Voraussetzung zu schaffen, wird in der Schweizer Patentanmeldung Nr. 00339/11 beschrieben. Um die dort aufgezeigten Verfahrensschritte bezüglich Weg und Zeit sicher durchführen zu können, werden hohe Ansprüche an die Aktorik der Fadenschneid- und Anstickvorrichtung gestellt. Nebst dem Schneiden der Fäden und dem Annähen oder Ansticken werden auf Haushaltnähmaschinen auch andere Funktionen bedarfsweise zugeschaltet, welche eine von der Hauptwelle angetriebene Aktorik mit einem weg- und zeitabhängigen Verlauf aufweisen müssen.When sewing, and especially when embroidering on household sewing machines, the pattern design necessitates frequent completion of a seam and a new beginning of a seam or embroidery pattern. It is important that on the one hand the completion of a seam and cutting the threads and the position of the ends of the cut threads is optimally executed and that when sewing or embroidering a new seam and the first stitches are done with rich nodes. One possible method of achieving this requirement is described in Swiss patent application no. 00339/11 described. In order to be able to carry out the process steps shown there with respect to travel and time safely, high demands are placed on the actuators of the thread trimming and embroidery device. In addition to cutting the threads and the sewing or embroidering are on household sewing machines and others Functions as needed, which must have a driven by the main shaft actuators with a path and time-dependent course.

Eine Aufgabe der vorliegenden Erfindung besteht nun darin, eine Aktivierungsvorrichtung zu schaffen, welche durch die Hauptwelle der Nähmaschine angetrieben wird und so zwangsweise einen synchronen weg- und zeitabhängigen, auf die durchzuführenden Funktionen abgestimmten Ablauf der Verfahrensschritte ermöglicht.An object of the present invention is to provide an activation device, which is driven by the main shaft of the sewing machine and thus forcibly allows a synchronous path and time-dependent, tailored to the functions to be performed sequence of process steps.

Gelöst wird diese Aufgabe durch eine Aktivierungsvorrichtung mit den Merkmalen des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungen der Aktivierungsvorrichtung sind in den abhängigen Ansprüchen umschrieben.This object is achieved by an activation device with the features of claim 1. Further advantageous embodiments of the activation device are described in the dependent claims.

Die erfindungsgemässe Aktivierungsvorrichtung weist einen einfachen Aufbau auf und ist daher kostengünstig herstellbar. Alle Funktionen verlaufen zwangsweise synchron zur Hauptwelle und damit zu den stichbildenden Organen der Nähmaschine. Die Auslösung der verschiedenen Bewegungen bezüglich Zeitpunkt und Weg erfolgt durch einen einzigen Hubmagneten, wobei die Einkupplung der mechanischen Elemente wiederum unabhängig vom exakten Zeitpunkt der Aktivierung durch den Hubmagneten direkt über synchron zu den stichbildenden Elementen umlaufenden Nocken erfolgt. Der einzig richtige und vorgegebene Startpunkt ist dadurch sichergestellt.The inventive activation device has a simple structure and is therefore inexpensive to produce. All functions are forced synchronously to the main shaft and thus to the stitch-forming organs of the sewing machine. The triggering of the various movements with respect to time and way is done by a single solenoid, the coupling of the mechanical elements in turn, regardless of the exact time of activation by the solenoid directly over synchronous to the stitch-forming elements Cam takes place. The only correct and predetermined starting point is thereby ensured.

In der Skelettdarstellung der Antriebselemente einer Nähmaschine 1 ist eine Stichplatte 3 und darunter ein Greiferaufnahme 5 ohne Spulenkapsel dargestellt. Links von der Stichplatte 3 ist der hintere Teil einer Schneid- und Anstickeinheit 7 sichtbar. Mit Bezugszeichen 9 ist die Hauptwelle bezeichnet, welche an ihrem linken Ende mit dem Greifer 11 verbunden ist und an deren hinteren Ende eine erste Riemenscheibe 13 für den Übertrieb von der Hauptwelle 9 auf eine zweite Riemenscheibe 15 auf der Oberwelle 17 angeordnet ist. Das vordere Ende der Oberwelle 17 steht in Wirkverbindung mit dem Antrieb für die Nadelstange 19 und weiteren für die Erzeugung einer Naht notwendigen Elemente.In the skeleton representation of the drive elements of a sewing machine 1, a throat plate 3 and below a gripper receptacle 5 is shown without bobbin case. To the left of the throat plate 3, the rear part of a cutting and embroidering unit 7 is visible. Reference numeral 9 denotes the main shaft, which is connected at its left end to the gripper 11 and at the rear end of a first pulley 13 is arranged for the overdrive of the main shaft 9 to a second pulley 15 on the upper shaft 17. The front end of the harmonic 17 is in operative connection with the drive for the needle bar 19 and other necessary for the production of a seam elements.

Nachfolgend wird als erstes eine erste Aktorik 21 für den Bewegungsablauf der Schneid- und Anstickeinheit für den Schneidprozess beschrieben und anschliessend eine zweite Aktorik 23 für die Betätigung einer Fadenbremse 25 zur Steuerung der Oberfadenspannung. Der Bewegungsblauf beim Annähen oder Ansticken erfolgt analog, jedoch durch eine zweite Kulisse.Subsequently, a first actuator 21 for the movement of the cutting and embroidering unit for the cutting process will be described first, followed by a second actuator 23 for the operation of a yarn brake 25 for controlling the upper thread tension. The movement when sewing or embroidering is analogous, but by a second backdrop.

Die Figur 2 zeigt in der vergrösserten Darstellung den Greifer 11, die Schneid- und Anstickeinheit 7 und das Getriebe 27 für den Übertrieb von der Hauptwelle 9 zu einer Ritzelwelle 29 für ein Ritzel 31, welches über einen Zahnriemen 33 den Greifer 1 antreibt. Weiter ist in Figur 2 ein um eine Welle 35 schwenkbarer Hebel 37 zum linearen Verschieben der nicht stationär angeordneten Elemente Schneid- und Anstickeinheit 7 sichtbar.The FIG. 2 shows in the enlarged view the gripper 11, the cutting and embroidering unit 7 and the gear 27 for the overdrive of the main shaft 9 to a pinion shaft 29 for a pinion 31, which drives the gripper 1 via a toothed belt 33. Next is in FIG. 2 a pivotable about a shaft 35 lever 37 for linear displacement of the non-stationary arranged elements cutting and Anstickeinheit 7 visible.

Das Ritzel 31 umfasst im Zentrum eine Scheibe 39, in welcher auf beiden Stirnflächen umlaufende Kulissen bildende Nuten eingelassen sind. Die erste Nut 41 dient der Führung eines ersten Bolzens 45 an einem äusseren Schalthebel 47 für den Bewegungsablauf beim Schneiden. Die zweite Nut oder Kulisse 43 dient der Führung eines zweiten Bolzens 49 für die Führung eines inneren Schalthebels 51 für den Bewegungsablauf beim Annähen. "Aussen" bedeutet näher bei der Gehäusewand des Nähmaschinenunterarms, "innen" bedeutet im Zentrum, in der Nähe der Hauptwelle 9, gelegen.The pinion 31 comprises in the center a disc 39, in which circumferential grooves on both end faces forming grooves are recessed. The first groove 41 serves to guide a first pin 45 on an outer shifter 47 for the movement sequence during cutting. The second groove or gate 43 serves to guide a second pin 49 for the guidance of an inner shift lever 51 for the movement during sewing. "Outside" means closer to the housing wall of the sewing machine forearm, "inside" means located in the center, near the main shaft 9.

Zur Durchführung eines Schneidvorgangs der Fäden am Ende einer Naht, der durch ein Signal der Näherin, z.B. durch einen Tastendruck erfolgt, wird bei einem Oberwellenwinkel von 220° die Aktivierung der Fadenschneideinheit 7 (nicht detailliert dargestellt) ausgelöst. In der Figur 3, welche, im Gegensatz zu den Figuren 1 und 2, eine Ansicht des Ritzels 31 für den Zahnriemen 33 von hinten zeigt, sind auf einer Basisplatte oder direkt auf dem Rahmen der Nähmaschine ein Kupplungsschlitten 55 und, mit diesem fest verbunden, eine Wippe 57 dargestellt. An der Wippe 57 sind der äussere Schalthebel 47 und der innere Schalthebel 51 angelenkt und mit einem Kupplungshebel 59 verbunden. Der Kupplungshebel 59 steht mit seinem freien Ende im Kontakt mit einem Stellring 61, auf dessen Stirnfläche Bolzen 63 angeordnet sind. Der Stellring 63 sitzt auf der Hauptwelle 9 (in den Figuren 3 ff. ist die Hauptwelle 9 nicht dargestellt) und wird von dieser beim Nähen oder Sticken synchron angetrieben. Durch einen Magnet 65 kann der Kupplungshebel 59 um eine vertikal liegende Achse A geschwenkt werden, um in Eingriff mit einem der beiden Bolzen 63 am Stellring 61 zu gelangen. Im vorliegenden Beispiel in den Eingriff für das Schneiden der Fäden bei einem Anfangswinkel von 220°.To carry out a cutting operation of the threads at the end of a seam, which is effected by a signal of the seamstress, for example by pressing a key, the activation of the thread cutting unit 7 (not shown in detail) is triggered at a harmonic angle of 220 °. In the FIG. 3 , which, in contrast to the FIGS. 1 and 2 , A view of the pinion 31 for the timing belt 33 shows from behind, are on a base plate or directly on the frame of the sewing machine, a coupling carriage 55 and, fixedly connected to this, a rocker 57 is shown. On the rocker 57, the outer shift lever 47 and the inner shift lever 51 are articulated and connected to a clutch lever 59. The clutch lever 59 is at its free end in contact with a collar 61, on the end face bolts 63 are arranged. The adjusting ring 63 is seated on the main shaft 9 (in the Figures 3 ff. The main shaft 9 is not shown) and is driven synchronously by this when sewing or embroidering. By a magnet 65, the clutch lever 59 can be pivoted about a vertical axis A in order to reach into engagement with one of the two bolts 63 on the adjusting ring 61. In the present example in the engagement for the cutting of the threads at an initial angle of 220 °.

Nachfolgend wird nun die Auslösung der Funktionen durch die Aktivierungsvorrichtung für den Kupplungsschlitten 55 bzw. den Antrieb der Schneid- und Anstickeinheit 7 beschrieben. Nach der Aktivierung des Magneten 65 schwenkt der Kupplungshebel 59, wie in Figur 4 gezeigt, im Uhrzeigersinn (Pfeil P+) und gelangt in Eingriff mit einem der Bolzen 63 und zwar mit demjenigen Bolzen 63, der für den Schneidvorgang zuständig ist (Figuren 5 und 6). Dies bedeutet, dass der Kupplungshebel 59 den äusseren Schalthebel 47 im Gegenuhrzeigersinn schwenkt, indem der Bolzen 63 den Kupplungshebel 61 nach hinten schiebt, bis der Kupplungsbolzen 67 am freien Ende des Hebels 47 in die Nut oder Kulisse 41 an der ersten Riemenscheibe 13 eingreift. In den Figuren 3 bis 5 ersichtlich, dass nach 40°-Drehung der Oberwelle der Kupplungsbolzen 67 vollständig in Eingriff mit der Kulisse 41 gelangt. Da die Kulisse 41 keinen konzentrischen Kreis zur Achse der Ritzelwelle 29 beschreibt, sondern eine Kurve, welche den Ablauf des Schneidens gemäss einem vorgegebenen Weg- und Zeitprogramm erzeugt, wird der äussere Schalthebel 47, welcher horizontal geführt ist, in Längsrichtung, hier in + X nach links geführt. Dadurch wird über den Kupplungsschlitten 55 die Schneideinheit in Figur 1 nach rechts geführt.The triggering of the functions by the activation device for the coupling carriage 55 or the drive of the cutting and embroidering unit 7 will now be described below. After activation of the magnet 65, the clutch lever 59 pivots as shown in FIG FIG. 4 shown in the clockwise direction (arrow P +) and engages with one of the bolts 63 and that with the pin 63, which is responsible for the cutting process ( Figures 5 and 6 ). This means that the clutch lever 59 pivots the outer shift lever 47 in the counterclockwise direction by the bolt 63 pushes the clutch lever 61 to the rear until the coupling pin 67 engages at the free end of the lever 47 in the groove or link 41 on the first pulley 13. In the FIGS. 3 to 5 It can be seen that after 40 ° rotation of the harmonic of the coupling pin 67 completely engages the link 41. Since the link 41 describes no concentric circle to the axis of the pinion shaft 29, but a curve which generates the sequence of cutting according to a predetermined path and time program, the outer shift lever 47, which is guided horizontally, in the longitudinal direction, here in + X led to the left. As a result, via the coupling carriage 55, the cutting unit in FIG. 1 led to the right.

In den Figuren 7 bis 10 sind die einzelnen Verschiebeabschnitte ersichtlich und der maximale Vorschub erfolgt in der Situation gemäss Figur 9. Im Bereich von beispielsweise 0° bis 60° Oberwellenwinkel weist die Kulisse 41 einen konstanten Radius auf und daher erfolgt dann keine Bewegung des Kupplungsschlittens 55. Kurz vor einer vollen Umdrehung der Hauptwelle bei ca. 190° wird der Kupplungshebel 59 vom Bolzen 63 am Stellring 61 wieder aus der Kulisse 41 herausgezogen und gelangt dann bereits bei 215°, d.h. 5° vor der vollen Umdrehung ausser Eingriff mit der Kulisse 41. Der Schneidvorgang ist dann beendet.In the FIGS. 7 to 10 the individual displacement sections are visible and the maximum feed takes place in the situation according to FIG. 9 , In the range of, for example, 0 ° to 60 ° harmonic angle, the link 41 has a constant radius and therefore no movement of the coupling carriage 55 takes place. Shortly before a full rotation of the main shaft at 190 °, the clutch lever 59 from the pin 63 on the adjusting ring 61st pulled out of the gate 41 again and then passes already at 215 °, ie 5 ° before the full revolution out of engagement with the gate 41. The cutting process is then completed.

In analoger Weise verläuft der Antrieb der Anstickeinheit 7, jedoch wird durch das Einkuppeln des Kupplungshebels 59 in den zweiten Stellringbolzen 63 in einer anderen Drehwinkelposition der Oberwelle der Kupplungshebel 59 derart bewegt, dass der innere Schalthebel 51 im Uhrzeigersinn bewegt und der an dessen freien Ende angeordneten Kupplungsbolzen 69 in die zweite Nut oder Kulisse 43 eingreift. In Figur 3 ist ersichtlich, dass der zweite Kupplungsbolzen 49 beabstandet zur Kulisse 43 liegt und so verharrt bis der Anstickvorgang ausgelöst wird. Zudem ist die Länge des inneren Schalthebels 51 wesentlich kürzer als diejenige des äusseren Schalthebels 53, sodass der Eingriff in die Kulisse 43, die nicht die gleiche geometrische Formgebung aufweist wie die äussere Kulisse 41, einen völlig anderen Bewegungsablauf verursacht als dies beim Schneiden der Fäden der Fall ist. Dadurch erfolgt der Eingriff des zweiten Bolzens 49 in die zweite Nut 43 zu einem anderen Zeitpunkt bzw. in einer anderen Winkelposition der Oberwelle 17 als beim Schneiden. Dadurch werden die Fäden an der Fadenschneid- und Anstickeinheit 7 nach einem anders verlaufenden Weg- und Zeitablauf geführt als beim Schneiden und es kann die entsprechende Funktion des Anstickens erreicht werden.In an analogous manner, the drive of the embroidery unit 7, however, is moved by the engagement of the clutch lever 59 in the second adjusting ring pin 63 in another rotational angle position of the harmonic of the clutch lever 59 such that the inner shift lever 51 moves in the clockwise direction and arranged at the free end Coupling pin 69 engages in the second groove or gate 43. In FIG. 3 It can be seen that the second coupling pin 49 is spaced from the backdrop 43 and so remains until the Anstickvorgang is triggered. In addition, the length of the inner shift lever 51 is substantially shorter than that of the outer shift lever 53, so that the engagement in the link 43, which does not have the same geometric shape as the outer link 41, causes a completely different sequence of motions than when cutting the threads of the Case is. This results in the engagement of the second pin 49 in the second Groove 43 at another time or in a different angular position of the harmonic 17 than when cutting. As a result, the threads are guided at the thread cutting and Anstickeinheit 7 for a different path and time course than when cutting and it can be achieved the corresponding function of Anstickens.

In den vergrösserten Darstellungen des Stellrings 61 mit dem Bolzen 63 sowie des Kupplungshebels 59 ist deren gegenseitige Lage ersichtlich. Der Kupplungshebel 59 ist noch nicht an die Bolzen 63 herangeführt und es erfolgt daher keine Bewegung des inneren Schalthebels 51. Durch das Auslösen des Näh- oder Anstickvorgangs durch den Magnet 65 schwenkt der Kupplungshebel 59 im Uhrzeigersinn auf den Stellring 61 zu und der im Bild in Drehrichtung vorne liegende Bolzen 63 gelangt in Anlage mit der Kante 53. Dadurch wird der Kupplungshebel 59 in Richtung des Pfeils V nach vorne gezogen und dadurch der innere Schalthebel 51 im Uhrzeigersinn geschwenkt und dessen am Ende des Schalthebels 51 angebrachte zweite Bolzen 49 in die zweite Nut 43 eingeführt. Sobald diese formschlüssige Verbindung aufgebaut ist, wird der innere Schalthebel 51 durch den Verlauf der zweiten Nut 43 linear verschoben, und zwar nach dem durch die Kulissenform vorgegebenen Wegzeitdiagramm.In the enlarged views of the adjusting ring 61 with the bolt 63 and the clutch lever 59 whose mutual position can be seen. The clutch lever 59 is not yet brought to the bolt 63 and therefore there is no movement of the inner lever 51. By triggering the sewing or Anstickvorgangs by the magnet 65 of the clutch lever 59 pivots clockwise on the adjusting ring 61 and in the picture in As a result, the clutch lever 59 is pulled forward in the direction of the arrow V, and thereby the inner shift lever 51 is pivoted clockwise and the second pin 49 attached to the end of the shift lever 51 into the second groove 43 introduced. Once this positive connection is established, the inner shift lever 51 is linearly displaced by the course of the second groove 43, and that according to the predetermined by the gate shape Wegzeitdiagramm.

In der Figur 14 sind die Unterschiede zwischen dem Schneidprozess und dem Anstickprozess nochmals schematisch dargestellt. Beim zuerst beschriebenen Schneidprozess (rechte Abbildung in Figur 14) ist ersichtlich, dass die beiden Kulissen 41 und 43 eine unterschiedliche geometrische Form aufweisen und folglich zu zwei völlig verschiedenen Bewegungsabläufen führen, nach welchen der Kupplungsschlitten 55 und mit diesem die Schneid- und Anstickeinheit 7 geführt wird.In the FIG. 14 The differences between the cutting process and the Anstickprozess are again shown schematically. For the first described cutting process (right figure in FIG. 14 ) it can be seen that the two scenes 41 and 43 have a different geometric shape and thus lead to two completely different sequences of motion, after which the coupling carriage 55 and with this the cutting and Anstickeinheit 7 is guided.

Um den Näh- und Stickprozess, aber auch das Schneiden der Fäden am Ende einer Naht optimal durchführen zu können, muss auch die Fadenspannung des Oberfadens durch die Fadenbremse 25 an die jeweiligen Prozessschritte beim Schneiden und beim Ansticken angepasst werden.In order to optimally perform the sewing and embroidery process, but also the cutting of the threads at the end of a seam, the thread tension of the upper thread must be adjusted by the yarn brake 25 to the respective process steps during cutting and embroidering.

In den Figuren 15 bis 19 wird nun die Funktionsweise bzw. die Aktivierung der Fadenbremse 25 aufgrund der jeweiligen Drehlage der Hauptwelle 9 bzw. Oberwelle 17 beschrieben. Wie bereits in der Übersichtsdarstellung in Figur 1 ersichtlich, erfolgt das Aktivieren der Fadenbremse 25 durch einen zweiarmigen Hebel 71, der um einen Schwenkpunkt 73 schwenkbar ist. Das eine Ende des Hebels 71 steht in Kontakt mit dem Kupplungsschlitten 47 (vgl. Figur 3), d.h. alle Bewegungen, die während des Schneid-und Anstickprozesses vom Kupplungsschlitten 55 ausgeführt werden, werden auch auf den Hebel 71 übertragen. Das andere Ende des Hebels 71 steht in Eingriff mit der Aktorik 23 (vgl. Figur 1), welche den zeitlichen Verlauf und Betrag der Schliesskraft der Fadenbremse 25 steuert. Die zweite Aktorik 23 umfasst gemäss Figur 15 eine Kurventrommel 75 mit einer auf deren Peripherie eingelassenen Kurve 77. An einer der Stirnflächen der Kurventrommel 75 kann eine teilweise radial offene Führungsnut 79 eingelassen sein, welche einen Haltestift 81 an einem Schwenkhebel 83 derart führt, dass ein Führungsstift 85 am Schwenkhebel 83, welcher in die Kurve 77 an der Kurventrommel 75 eingeschwenkt wird, sicher in der Kurve 77 verharrt, bis eine vollständige oder annähernd vollständige Drehung der Oberwelle 17 erfolgt ist (vgl. Figuren 17 und 18a-c).In the FIGS. 15 to 19 Now, the operation and the activation of the thread brake 25 due to the respective rotational position of the main shaft 9 and harmonic 17 will be described. As already mentioned in the overview in FIG. 1 can be seen, the activation of the thread brake 25 by a two-armed lever 71 which is pivotable about a pivot point 73. The one end of the lever 71 is in contact with the coupling carriage 47 (see. FIG. 3 ), ie all movements that are performed by the coupling carriage 55 during the cutting and Anstickprozesses be transferred to the lever 71. The other end of the lever 71 is engaged with the Actuator 23 (cf. FIG. 1 ), which controls the timing and amount of the closing force of the thread brake 25. The second actuator 23 comprises according to FIG. 15 a cam drum 75 with a recessed on its periphery curve 77. At one of the end surfaces of the cam drum 75 may be a partially radially open guide groove 79 is inserted, which guides a retaining pin 81 on a pivot lever 83 such that a guide pin 85 on the pivot lever 83, which in the curve 77 is pivoted to the cam drum 75, safely in the curve 77 remains until a complete or approximately complete rotation of the harmonic 17 is carried out (see. Figures 17 and 18a-c ).

Die zweite Aktorik 23 arbeitet wie folgt. Durch den zweiarmigen Hebel 71 wird beim Schwenken desselben dessen Ende 71a bewegt und der Kupplungshebel 83 über einen Stab 89 nach unten gedrückt und der Führungsstift 85 in die Kurve 77 eingeschwenkt. Durch die konstante Drehung der Oberwelle 17 und die Ausbildung der Kurve 77 bewegt sich der Schwenkhebel 83 zuerst in X-Richtung. Dabei zieht er eine Öffnerlasche 91 (Figur 13) mit. Durch diese Bewegung berührt sie eine Gabel 93 an der Öffnungslasche 91 und zieht auch diese mit. Die Gabel 93 bewegt ebenfalls ein Druckstück 95, wodurch die Fadenbremse 25 geöffnet wird. Die Dauer der Öffnung der Fadenbremse 25 wird durch die Kurve 77 gesteuert. Ab einem bestimmten Zeitpunkt muss die Fadenbremse 25 möglichst schnell wieder geschlossen werden. Mit Hilfe einer Drückerlasche 97 kann diese Aktion durchgeführt werden. Die Drückerlasche 97 ist auf einer verlängerten Welle der Fadenbremse 25 gelagert und in X-sowie in -X-Richtung beweglich.The second actuator 23 operates as follows. By the two-armed lever 71 of the same when pivoting its end 71 a is moved and the clutch lever 83 is pressed by a rod 89 down and the guide pin 85 is pivoted into the curve 77. Due to the constant rotation of the upper shaft 17 and the formation of the curve 77, the pivot lever 83 moves first in the X direction. He pulls an opener tab 91 ( FIG. 13 ) With. By this movement, it touches a fork 93 on the opening tab 91 and pulls along with them. The fork 93 also moves a pressure piece 95, whereby the yarn brake 25 is opened. The duration of the opening of the yarn brake 25 is controlled by the curve 77. At a certain point in time, the thread brake 25 must be closed again as quickly as possible become. With the help of a handle tab 97, this action can be performed. The pusher tab 97 is mounted on an extended shaft of the thread brake 25 and movable in the X and in the -X direction.

In Figur 19 ist eine weitere Ausgestaltung der Erfindung für die Übertragung des Steuerbefehls von der ersten Aktorik 21 auf die zweite Aktorik 23 mittels eines Bowdenzugs 99 dargestellt. Der Bowdenzug 99 wird nicht direkt vom Kupplungsschlitten 55 betätigt, sondern über eine dritte Aktorik 101 (gemäss Figur 20). Die dritte Aktorik 101 umfasst einen Hauptträger 103, auf dem zwei Schlitten 105 und 107 linear verschiebbar angeordnet sind. Jeder Schlitten 105, 107 trägt je eine Klinke 109 und 111, welche Klinken 109, 111 jeweils um eine Drehachse auf den Schlitten 105 bzw. 107 schwenkbar sind. Die zweite Klinke 111 ist mit einer Verbindungslasche 113 am Kupplungsschlitten 55 verbunden. Bewegt sich der Kupplungssschlitten 55, angetrieben durch die erste Aktorik 21, in +X-Richtung, so stösst die zweite Klinke 111 an den Anschlag eines Auslöserschlittens 115. Sobald dieser dort ansteht, wird er mitbewegt. Sobald der zweite Kupplungsschlitten 107 den maximal möglichen Hub gefahren ist, befinden sich die beiden Klinken 109 und 111 hintereinander. Das heisst, deren hakenförmigen Enden 117 und 119 rasten ineinander ein.In FIG. 19 a further embodiment of the invention for the transmission of the control command from the first actuator 21 to the second actuator 23 by means of a Bowden cable 99 is shown. The Bowden cable 99 is not actuated directly by the coupling carriage 55, but via a third actuator 101 (according FIG. 20 ). The third actuator 101 comprises a main carrier 103, on which two carriages 105 and 107 are arranged linearly displaceable. Each carriage 105, 107 carries a respective pawl 109 and 111, which pawls 109, 111 are each pivotable about an axis of rotation on the carriage 105 and 107, respectively. The second pawl 111 is connected to a connecting lug 113 on the coupling carriage 55. If the coupling carriage 55, driven by the first actuator 21, moves in the + X direction, the second pawl 111 pushes against the stop of a trigger carriage 115. As soon as it is there, it is moved along. As soon as the second coupling slide 107 has moved the maximum possible stroke, the two pawls 109 and 111 are located one behind the other. That is, their hook-shaped ends 117 and 119 engage with each other.

Wenn sich nun der zweite Kupplungsschlitten 107 in die entgegengesetzte Richtung (-X) bewegt, bleiben die beiden Klinken 109 und 111 vorerst stehen und es findet ein Leerhub statt, und zwar deshalb, weil der Auslöseschlitten 115 zur Ausgangslage zurückfährt. Erst am Ende dieses Leerhubs wirkt die Verbindung der beiden Klinken 109 und 111. Dann ist der erste Schlitten 105 an einem Auslöser 121 angelangt. Der Auslöser 121 ist als verstellbarer Exzenter ausgebildet, mit dem der Auslösezeitpunkt eingestellt werden kann. Durch das Überfahren dieses Auslösepunkts wird die Verbindungslasche 109 geschwenkt und die Klinkenverbindung aufgehoben.Now, when the second coupling slide 107 moves in the opposite direction (-X), the two pawls remain 109 and 111 for the time being and there is a no-lift, and that is because the release carriage 115 moves back to the starting position. Only at the end of this idle stroke, the connection of the two pawls acts 109 and 111. Then the first carriage 105 has arrived at a trigger 121. The trigger 121 is designed as an adjustable eccentric, with which the triggering time can be adjusted. By overrunning this trigger point, the connecting tab 109 is pivoted and lifted the latch connection.

Selbstverständlich ist die beanspruchte Aktivierungsvorrichtung auch auf andere weg- und zeitabhängige Verfahren als das Schneiden und Annähen an der Nähmaschine einsetzbar.Of course, the claimed activation device can also be used on other path and time-dependent methods than cutting and sewing on the sewing machine.
