Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zum Wechseln einer Unterfadenspule an einer Näh- oder Stickmaschine mit einem Greifer, wobei die Näh- oder Stickmaschine eine Spulenkapsel aufweist, die mit einem federelastisch an der Unterfadenspule angelenkten Öffnungsfinger zum Lösen einer Fixierung auf einem Mittelzapfen versehen ist. Der Greifer weist einen Hebel zum Anheben des Öffnungsfingers der Spulenkapsel zur Aufhebung der Fixierung auf, wobei derselbe Hebel die Spulenkapsel durch Klemmung gegen eine Rampe in dem Greifer fixiert.The present invention relates to a device for changing a bobbin on a sewing or embroidery machine with a gripper, wherein the sewing or embroidery machine has a bobbin case, which is provided with a resiliently hinged to the lower bobbin opening finger for releasing a fixation on a center pin. The gripper has a lever for lifting the opening finger of the bobbin case to release the fixation, wherein the same lever fixes the bobbin case by clamping against a ramp in the gripper.

Um eine bekannte Vorrichtung unter Vereinfachung bei weiterer Erhöhung der Betriebszuverlässigkeit der Vorrichtung weiterzubilden, wird vorgeschlagen, dass an dem Greifer (2) mindestens ein zum Eingreifen in eine Ausnehmung (7) der Spulenkapsel (3) ausgebildeter Dorn (6) vorgesehen ist.
