Abstract
Ein Greifer für eine Doppel-Steppstich-Nähmaschine weist einen topfförmigen Greifer-Körper (24) und eine dem Greifer-Körper (24) um eine Achse (9) drehbar angeordnete Spulenkapsel (21) auf, die einen Boden (33) und konzentrisch zur Achse (9) einen Lager-Zapfen (25) aufweist. Auf dem Lager-Zapfen (25) ist eine in Richtung der Achse (9) verschiebbar angeordnete Spulen-Lager-Einrichtung (31a) zur Aufnahme einer Greiferfaden-Spule (26) angeordnet. Weiterhin ist zwischen dem Boden (33) und der Spulen-Lager-Einrichtung (31a) eine Ausschub-Feder (34) angeordnet. Zwischen der Spulen-Lager-Einrichtung (31a) und einer Greiferfaden-Spule (26) ist eine Brems-Feder (36) vorgesehen.A gripper for a double-lockstitch sewing machine has a pot-shaped gripper body (24) and a the bobbin body (24) about an axis (9) rotatably mounted bobbin case (21) having a bottom (33) and concentric with Axis (9) has a bearing pin (25). On the bearing pin (25) arranged in the direction of the axis (9) slidably coil-bearing device (31a) for receiving a looper thread bobbin (26) is arranged. Furthermore, between the bottom (33) and the coil-bearing device (31 a) a Ausschub spring (34) is arranged. A brake spring (36) is provided between the spool bearing means (31a) and a hook thread spool (26).
Description
Die Erfindung betrifft einen Greifer für eine Doppel-Steppstich-Nähmaschine mit einem topfförmigen Greifer-Körper mit einer in dem Greifer-Körper um eine Achse drehbar angeordneten Spulenkapsel, die einen Boden und konzentrisch zur Achse einen Lager-Zapfen aufweist.The The invention relates to a gripper for a double-lockstitch sewing machine with a cup-shaped gripper body with one in the gripper body an axis rotatably arranged bobbin case, which has a bottom and concentric with the axis has a bearing pin.

einem derartigen, aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Greifer der allgemeinen Gattung in einfacher Weise so auszugestalten, dass ein Vorlauf der Spule beim Reduzieren der Nähgeschwindigkeit oder beim Anhalten der Nähmaschine vermieden wird.Of the Invention is based on the object, a gripper of the general Genus in a simple way to design so that a flow of the Coil reducing the sewing speed or when stopping the sewing machine is avoided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Durch die Erfindung wird in sehr einfacher Weise erreicht, dass das Bremsen der Spule gegen einen Vorlauf einerseits und das Ausschieben der Spule beim Spulenwechsel andererseits funktionell voneinander getrennt werden. Durch die Brems-Feder wird die Spule gegen uner wünschten Fadenvorlauf abgebremst. Die Federkraft dieser Brems-Feder kann so ausgelegt werden, dass nur diese Aufgabe optimal erfüllt wird. Für das Ausschieben der Spule kann wiederum die Ausschub-Feder so dimensioniert werden, dass eine ausreichende Federkraft hierfür zur Verfügung steht.These The object is achieved by the Characteristics of claim 1 solved. By the invention is achieved in a very simple manner that the Braking the coil against a flow on the one hand and pushing out on the other hand, the bobbin is functionally different from each be separated. By the brake spring, the coil is against uner wished Thread feed slowed down. The spring force of this brake spring can be designed so that only this task is optimally fulfilled. For the Pushing out the coil, in turn, the Ausschub spring dimensioned so be that a sufficient spring force is available for this purpose.
