Description

Die Erfindung betrifft eine Nähmaschine nach dem Oberbegriff des Anspruches 1 (siehe Dokument US-A-5 025 738).The invention relates to a sewing machine according to the preamble of Claim 1 (see document US-A-5 025 738).

Wenn vor Beginn eines Nähvorganges der Stoffdrückerfuß der Nähmaschine auf das Nähgut abgesenkt wird, sollte das von der Nadel herabhängende Fadenende nicht unter dem Stoffdrückerfuß liegen, weil sonst die Gefahr besteht, daß das Fadenende zwischen dem Stoffdrückerfuß und dem Nähgut eingeklemmt wird. Dies hätte zur Folge, daß das Fadenende zu Beginn des Nähvorganges nicht auf die Unterseite des Nähgutes gezogen werden könnte, sondern auf der Oberseite als abstehendes, das Erscheinungsbild der Naht beeinträchtigendes Fadenende verbliebe.If the presser foot of the sewing machine before starting a sewing process is lowered onto the material to be sewn, the one hanging from the needle Do not lie the thread end under the presser foot, otherwise the There is a risk that the thread end between the presser foot and the Material is jammed. This would have the consequence that the thread end too Do not pull the beginning of the sewing process onto the underside of the sewing material could be, but on the top as a protruding that The appearance of the seam impairing the thread end would remain.

Um dies zu verhindern, ist es z. B. durch die DE 25 26 694 C2 (US 3 901 171) bekannt, das Nadelfadenende mittels einer zwischen dem Stoffdrückerfuß und der Nadel hindurchbewegten, als Fadenwischer ausgebildeten Fadenwegzieheinrichtung aus dem Bereich des Stoffdrückerfußes herauszubewegen. Derartige Fadenwegzieheinrichtungen arbeiten sehr zuverlässig und werden daher häufig angewendet. Allerdings findet ihr Einsatz bei der Verarbeitung von sehr dickem Nähgut, wie z. B. Polsterware, eine Einschränkung, da in diesem Fall der Abstand zwischen dem Stoffdrückerfuß und der in angehobener Stellung befindlichen Nadel so eng sein kann, daß für die Hindurchbewegung des Fadenwischers kein ausreichender Platz zur Verfügung steht.To prevent this, it is e.g. B. by DE 25 26 694 C2 (US 3 901 171), the needle thread end by means of a between the The presser foot and the needle moved through as thread wipers trained thread pulling device from the area of the presser foot out move. Such thread path pulling devices work very reliably and are therefore often used. However, they are used in the processing of very thick Material such as B. upholstery, a limitation because in this case the distance between the presser foot and that in raised Position needle can be so tight that for the passage the thread wiper does not have sufficient space stands.

Bei der Verarbeitung von dickem Nähgut könnten dagegen solche Fadenwegzieheinrichtungen verwendet werden, bei denen das Nadelfadenende nicht durch einen mechanischen Fadenwischer, sondern durch einen Druckluftstrom aus dem Bereich des Stoffdrückerfußes herausbewegt wird. Eine derartige Fadenwegzieheinrichtung ist beispielsweise durch die US 3 371 632 bekannt. Solche Einrichtungen sind aber gegenüber mechanisch wirkenden Einrichtungen insofern nachteilig, als widerstandsfähige und ggf. zusätzlich noch drallbehaftete Fäden u. U. nur unzureichend aus dem Bereich des Stoffdrückerfußes weggezogen werden können und die Einrichtungen überdies einen vergleichsweise hohen Druckluft- und somit Energieverbrauch bedingen.In contrast, when processing thick sewing material, such Thread path pulling devices are used in which the needle thread end not by a mechanical thread wiper, but by one Compressed air flow moved out of the area of the presser foot becomes. Such a thread path pulling device is, for example, by US 3,371,632 is known. Such facilities are opposite Mechanically acting devices disadvantageous in that they are resistant and possibly also twisty threads u. U. only insufficiently pulled out of the area of the presser foot can and the facilities also have a comparatively high Compressed air and thus energy consumption.

Der Erfindung liegt die Aufgabe zugrunde, eine Fadenwegzieheinrichtung zu schaffen, die sowohl bei der Verarbeitung von dünnem als auch von besonders dickem Nähgut ohne Einschränkung verwendbar ist. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention has for its object a thread pulling device to create that both when processing thin and from particularly thick material can be used without restriction. The task is solved by the characterizing features of claim 1.

Die Erfindung beruht auf dem Gedanken, das Nadelfadenende durch den quer zum Weg des Nadelfadens bewegbaren Stift gerade so weit durch das Nadelöhr zurückzuziehen, daß einerseits der Stoffdrückerfuß beim Absenken das Fadenende nicht zwischen sich und dem Nähgut einklemmen kann und andererseits das aus dem Nadelöhr herabhängende Fadenende noch eine ausreichende Länge für die einwandfreie Fadenverknüpfung zu Beginn des nächsten Nähvorganges aufweist. Hierbei besteht eine wesentliche Voraussetzung für die sichere Fadenverknüpfung darin, daß die zurückgezogene Fadenmenge vor dem erneuten Nähstart freigegeben wird und auf diese Weise als freie Fadenreserve zur Verfügung steht.The invention is based on the idea that the needle thread end by the the pin can be moved across the path of the needle thread just as far through the To withdraw the eye of the needle that on the one hand the presser foot at Do not lower the thread end between yourself and the material can and on the other hand the thread hanging from the eye of the needle a sufficient length for the perfect thread linking Has the beginning of the next sewing process. There is a essential prerequisite for the secure thread linking is that the withdrawn amount of thread is released before starting sewing again and is thus available as a free thread reserve.

Durch das DE-GM 75 01 449 (US 3 847 102) ist eine Fadenwegzieheinrichtung bekannt, die außer einem Fadenwischer auch einen quer zum Weg des Nadelfadens bewegbaren Fadenrückziehstift aufweist. Dieser gleichzeitig mit dem Fadenwischer bewegbare Fadenrückziehstift soll die Wirkung des nur einen vergleichsweise kleinen Schwenkweg ausführenden Fadenwischers unterstützen, indem er zusätzlich eine kleine Fadenmenge durch das Nadelöhr zurückzieht. Da dieser Fadenrückziehstift somit neben dem eigentlichen Fadenwegziehmittel, nämlich dem Fadenwischer, nur als ein Hilfsmittel dient, indem er das durch den Fadenwischer u. U. nicht weit genug vom Stoffdrückerfuß entfernte Fadenende so weit verkürzt, daß es nicht mehr unter dem Stoffdrückerfuß eingeklemmt werden kann, konnte das DE-GM den erfindungsgemäßen Gedanken nicht nahegelegt haben, nämlich eine Fadenwegzieheinrichtung zu schaffen, die ausschließlich nur einen Fadenrückziehstift aufweist.By DE-GM 75 01 449 (US 3 847 102) is a thread pulling device known that besides a thread wiper also one across the path of the needle thread movable thread retraction pin. This Thread retraction pin that can be moved simultaneously with the thread wiper the effect of only a comparatively small swivel path Support executing thread wiper by adding an additional pulls a small amount of thread back through the eye of the needle. Because this thread retraction pin thus in addition to the actual thread pulling agent, namely the Thread wiper, only serves as an aid by doing this through the Thread wipers u. May not be far enough from the presser foot The thread end is shortened so much that it is no longer under the presser foot can be pinched, the DE-GM could the invention Have not suggested thoughts, namely a thread pulling device to create that only has a thread retraction pin.

Daß die erfindungsgemäße Maßnahme, das Einklemmen des Nadelfadenendes allein durch Verkürzen des Fadenendes zu verhindern, nicht naheliegend gewesen sein kann, ergibt sich insbesondere auch daraus, daß durch die DE-OS 1 933 780 (US 3 640 236) und die DE 22 07 366 B2 (US 3 695 200) vorgeschlagen wird, bei Verwendung eines Fadenwischers eine zusätzliche Fadenreserve für die sichere Fadenverknüpfung zu Beginn des nächsten Nähvorganges bereitzustellen, obwohl durch einen Fadenwischer die Länge des vom Nadelöhr herabhängenden Fadenendes unbeeinflußt bleibt und daher die Fadenverknüpfung zu Beginn des nächsten Nähvorganges nicht beeinträchtigt wird. Diese Fadenreserve wird dadurch erzeugt, daß ein quer zum Weg des Nadelfadens bewegbarer Fadenabziehstift vor dem Fadenschneiden eine bestimmte Fadenmenge durch die geöffnete Fadenspannvorrichtung hindurch vom Fadenvorrat abzieht und vor dem erneuten Nähstart wieder freigibt.That the measure according to the invention, the pinching of the needle thread end To prevent only by shortening the thread end, not obvious may have been, results in particular from the fact that by the DE-OS 1 933 780 (US 3 640 236) and DE 22 07 366 B2 (US 3 695 200) it is proposed to use an additional when using a thread wiper Thread reserve for secure thread linking at the beginning of the next sewing process, although by a thread wiper the length of the thread end hanging from the eye of the needle is unaffected remains and therefore the thread linkage at the beginning of the next Sewing process is not affected. This thread reserve will generated by a movable across the path of the needle thread Thread puller before thread cutting a certain amount of thread through the opened thread tensioning device from the thread supply subtracts and releases again before starting sewing again.

Fig. 3
a sectional view of the head cover.

Von der in Fig. 1 dargestellten Nähmaschine ist die Grundplatte mit 1, der Gehäusesockel mit 2 und der den Gehäusekopf verschließende Kopfdeckel mit 3 bezeichnet.1 of the sewing machine shown in FIG. the housing base with 2 and the head cover closing the housing head designated 3.

Die Nähmaschine weist in an sich bekannter Weise eine auf- und abbewegbare Nadelstange 4 mit einer fadenführenden Nadel 5, einen Fadengeber 6, eine Fadenspannvorrichtung 7 und eine zwischen einer Ruhe- und einer Andruckstellung auf- und abbewegbare Stoffdrückerstange 8 mit einem Stoffdrückerfuß 9 auf. In der Grundplatte 1 sind ein mit der Nadel 5 zusammenarbeitender Greifer 10 sowie eine Fadenschneideinrichtung 11 angeordnet. The sewing machine has and in a manner known per se movable needle bar 4 with a thread-guiding needle 5, one Thread feeder 6, a thread tensioning device 7 and one between one Rest and a pressure position up and down movable presser bar 8 with a presser foot 9. In the base plate 1 are a gripper 10 cooperating with the needle 5 and one Thread cutting device 11 arranged.

Auf der Innenseite des Kopfdeckels 3 ist auf einem Bolzen 12 ein Winkelhebel 13 gelagert, dessen Arme mit 14 und 15 bezeichnet sind. Der Arm 14 steht mit einem Druckluftzylinder 16 in Antriebsverbindung, indem ein Gelenkstift 17, der in einem an der Kolbenstange befestigten Gabelkopf 18 aufgenommen ist, in einen Schlitz 19 des Armes 14 eingreift. Der Druckluftzylinder 16 ist auf einem winkelförmigen Träger 20 angeordnet, der wiederum mittels Schrauben 21 am Kopfdeckel 3 höhenmäßig einstellbar ist.On the inside of the head cover 3 is on a bolt 12 Angle lever 13 mounted, the arms are designated 14 and 15. The arm 14 is in drive connection with a compressed air cylinder 16, by a hinge pin 17 which is attached to the piston rod in a Clevis 18 is received in a slot 19 of the arm 14 intervenes. The air cylinder 16 is angular Carrier 20 arranged, which in turn by means of screws 21 on the head cover 3 is adjustable in height.

Am Ende des Armes 15 ist ein quer abstehender Fadenrückziehstift 22 befestigt, dessen freies Ende zu einer Fadenöse 23 geformt ist. Der Druckluftzylinder 16 und der Winkelhebel 13 bilden gemeinsam eine Fadenwegzieheinrichtung 24.At the end of the arm 15 is a transverse thread retraction pin 22 attached, the free end is formed into a thread eyelet 23. The Air cylinder 16 and the angle lever 13 together form one Thread travel device 24.

Gemäß Fig. 2 kann der Winkelhebel 13 zwischen einer in Vollinien dargestellten Ruhestellung und einer strichpunktiert dargestellten Funktionsstellung hin- und hergeschwenkt werden. In der Ruhestellung befindet sich der Fadenrückziehstift 22 mit der Fadenöse 23 zwischen einer am Gehäusekopf befestigten Fadenöse 25 und einer an der Nadelstange 4 angebrachten Fadenöse 26. In dieser Stellung läuft der vom Fadengeber 6 kommende Nadelfaden 27 im wesentlichen geradlinig von der oberen Fadenöse 25 durch die Fadenöse 23 des Fadenrückziehstiftes 22 hindurch zur unteren Fadenöse 26 an der Nadelstange 4.2, the angle lever 13 between one in solid lines shown rest position and a dash-dotted line Functional position can be pivoted back and forth. At rest there is the thread retraction pin 22 with the thread eyelet 23 between a thread eyelet 25 attached to the housing head and one on the needle bar 4 attached thread eyelet 26. In this position runs from the Thread feeder 6 coming needle thread 27 substantially straight from the upper thread eyelet 25 through the thread eyelet 23 of the thread retraction pin 22 through to the lower thread eyelet 26 on the needle bar 4.

Der Winkelhebel 13 verbleibt während des Nähens in seiner Ruhestellung. Erst am Ende einer Naht wird nach dem Fadenschneiden bei wirksamer Fadenspannvorrichtung 7 der Druckluftzylinder 16 beaufschlagt, wodurch er den Winkelhebel 13 aus der Ruhestellung in die Funktionsstellung verschwenkt. Dabei bewegt sich der Fadenrückziehstift 22 quer zu dem von den beiden Fadenösen 25, 26 definierten Weg des Nadelfadens 27, wodurch er ihn, wie in Fig. 1 gezeigt, winkelförmig auszieht. Da hierbei der Nadelfaden 27 in der Fadenspannvorrichtung 7 reibschlüssig gehalten wird, zieht der Fadenrückziehstift 22 Faden durch die Fadenöse 26 der Nadelstange 4 und das nicht näher bezeichnete Öhr der Nadel 5 entgegen der normalen Fadenabzugsrichtung zurück und verkürzt auf diese Weise das aus dem Nadelöhr herabhängende Fadenende. Durch Justieren des Trägers 20 läßt sich die Lage der Ruhe- und der Funktionsstellung des Winkelhebels 13 so einstellen, daß die Länge des verkürzten Nadelfadenendes ein optimales Maß hat, d. h., daß es einerseits kurz genug ist, um nicht beim Absenken des Stoffdrückerfußes 9 auf ein neues Nähgutteil zwischen dem Stoffdrückerfuß 9 und dem Nähgutteil eingeklemmt zu werden und andererseits für die sichere Fadenverknüpfung zu Beginn eines neuen Nähvorganges lang genug ist. Hierbei ist es von großer Wichtigkeit, daß vor Beginn des nächsten Nähvorganges der Winkelhebel 13 in seine Ruhestellung zurückgeschwenkt wird, damit die zuvor zurückgezogene Fadenmenge jetzt als freie Fadenreserve zur Verfügung steht.The angle lever 13 remains in its rest position during sewing. It is only at the end of a seam after thread trimming effective thread tensioning device 7 of the compressed air cylinder 16, thereby moving the angle lever 13 from the rest position into the Function position pivoted. The thread retraction pin moves 22 transverse to the path defined by the two thread eyelets 25, 26 of the needle thread 27, thereby making it angular as shown in FIG. 1 undresses. Since here the needle thread 27 in the thread tensioning device 7 is held frictionally, the thread retraction pin pulls 22 thread through the thread eyelet 26 of the needle bar 4 and not closer designated eye of the needle 5 against the normal thread take-off direction back and in this way shortens that which hangs out of the eye of the needle Thread end. By adjusting the carrier 20, the position of the rest and the functional position of the angle lever 13 so that the Length of the shortened needle thread end has an optimal dimension, d. that is on the one hand it is short enough not to lower the presser foot 9 on a new workpiece between the presser foot 9 and the material to be pinched and on the other hand for the safe Thread linkage at the start of a new sewing process is long enough. It is of great importance that before the beginning of the next Sewing process of the angle lever 13 pivoted back into its rest position so that the thread quantity previously withdrawn is now available as a free thread reserve is available.
