Description

Die Erfindung betrifft den Antrieb eines Fadenlegers an Nähmaschinen, insbesondere an Stickmaschinen. Fadenleger sollen mit ihren Enden eine nähtechnisch optimale Kurvenbahn beschreiben; andererseits wachsen die Leistungsanforderungen beständig, und dies verlangt immer höhere Maschinengeschwindigkeiten. Die gleichzeitige Fortentwicklung nach diesen beiden Richtungen hin ist aber dadurch erschwert, daß die Forderung des genauen Einhaltens einer bestimmten Kurvenbahn der Vereinfachung des Fadenlegerantriebes enge Grenzen setzt, hohe Maschinengeschwindigkeiten aber gerade .die Antriebsvereinfachung zur Voraussetzung haben.The invention relates to the drive of a thread layer on sewing machines, especially on embroidery machines. Thread layers should have a sewing technique with their ends describe optimal curve path; on the other hand, the performance requirements grow constant, and this requires ever higher machine speeds. The simultaneous However, further development in these two directions is made more difficult by the fact that the requirement of the exact adherence to a certain curved path of the simplification of the thread layer drive sets narrow limits, but high machine speeds just have the drive simplification as a prerequisite.

Um diesen einander widerstrebenden Forderungen bestmöglich zu genügen, sieht die Erfindung vor, daß die nähtechnisch optimale Bewegung des Fadenlegers von zwei hintereinanderliegenden, fest verbundenen, hubmäßig aufeinander abgestimmten Kurvenscheiben abgeleitet wird, von welchen jede einen Teil eines Turnus der Fadenlegerbahn steuert. Eine solche Anordnung ermöglicht, mit einem geringeren Maß an schwingenden und geradlinig bewegten Antriebsteilen auszukommen, als dies bei bekannten Fadenlegerantrieben der Fall ist.In order to meet these conflicting demands as best as possible, the invention provides that the optimal sewing movement of the thread layer of two one behind the other, firmly connected and coordinated in terms of stroke Cam disks is derived, each of which is part of a rotation of the thread-laying path controls. Such an arrangement allows with a lesser degree of vibrating and drive parts moving in a straight line than is the case with known thread-laying drives the case is.

In der Zeichnung sind zwei Ausführungsformen der Erfindung beispielsweise dargestellt. Es zeigt Fig. i einen erfindungsgemäß gestalteten Fadenlegerantrieb mit geradlinig geführtem Schieber als Koppelglied in Seitenansicht, Fig. 2 den Antrieb nach Fi;g. i in Draufsicht, Fig. 3 einen erfindungsmäßig gestalteten Fadenlegerantrieb mit schwenkbarem Bügel als Koppelglied in Seitenansicht.In the drawing, two embodiments of the invention are for example shown. It shows Fig. I a thread-laying drive designed according to the invention with a linearly guided slide as a coupling link in a side view, Fig. 2 shows the drive according to Fi; g. i in plan view, FIG. 3 shows a thread layer drive designed according to the invention with swiveling bracket as a coupling link in side view.

Auf der Antriebswelle i sind zwei hintereinanderliegende, fest verbundene Kurvenscheiben 2 und 3 aufgesetzt und in ihrer Form so gestaltet, daß die eine den Aufwärtsgang, die andere den Abwärtsgang des Fadenlegers q. bewirkt, wobei die eine zur anderen hubmäßig abgestimmt ist. Beide Kurvenscheiben sind nach Fig. i mit einem in der Maulweite, dem Fertigungsmaß entsprechend einstellbaren, im festen Gehäuse 5 gelagerten, geradlinig geführten Schieber 6 (oder nach Fig. 3 mit einem im festen Gehäuse 5 gelagerten, schwingenden Bügel 7 als Schieberersatz) nach Fig. 2 so gekoppelt, daß an den Berührungslinien 8 und 9 des Schiebers 6 bzw. Bügels 7 immer die zugehörige Kurvenscheibe zur Anlage kommt.On the drive shaft i there are two firmly connected one behind the other Cams 2 and 3 placed and designed in shape so that the one Upward gear, the other the downward gear of the thread layer q. causes, the one to the other hub is coordinated. Both cams are shown in Fig. I with a in the mouth width, adjustable according to the production size, in the fixed housing 5 mounted, linearly guided slide 6 (or according to FIG. 3 with a fixed Housing 5 mounted, oscillating bracket 7 as a slide replacement) according to Fig. 2 so coupled, that at the contact lines 8 and 9 of the slide 6 or bracket 7 always the associated Cam comes to rest.

Die von den Kurvenscheiben 2 und 3 abgenommene, den nähtechnischen Forderungen optimal nachkommende Bewegung wird dann über bekannte Gelenke und Verbindungen zum Fadenleger q. geleitet.The one removed from the cams 2 and 3, the sewing technology Movement that is optimally compliant with demands is then made via known joints and connections to the thread layer q. directed.
