Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft einen für eine Stickmaschine geeigneten Stickkopf mit einem Nadelstangenantrieb.The Invention relates to a an embroidery machine suitable embroidery head with a needle bar drive.

Stickkopf einer Stickmaschine ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen gegenüber dem Stand der Technik verbesserten, besonders kompakt aufgebauten, einen Nadelstangenantrieb umfassenden Stickkopf anzugeben.Of the Invention is based on the object, a relation to the State of the art improved, particularly compact, a Specify the needle bar drive embroidery head.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Stickkopf mit den Merkmalen des Patentanspruchs 1. Dieser Stickkopf weist zum Antrieb einer Nadelstange einen elektrischen Direktantrieb auf, dessen Läufer fest mit der Nadelstange verbunden ist. Der Direktantrieb der Nadelstange hat zusätzlich zu seinem kompakten Aufbau den Vorteil eines praktisch wartungsfreien und verschleißfreien Betriebes. Zudem ist im Vergleich zu konventionellen Nadelstangenantrieben die erreichbare Stickgeschwindigkeit erhöht und der Energieverbrauch gesenkt. Dies gilt sowohl bei Ausbildung des elektrischen Direktantriebs als Reluktanzmotor als auch bei Ausführung als permanentmagneterregter Linearmotor.These The object is achieved by an embroidery head with the features of claim 1. This Embroidery head has an electric drive for driving a needle bar Direct drive on, whose runner firmly connected to the needle bar. The direct drive of the needle bar has in addition to Its compact design has the advantage of a virtually maintenance-free and wear-free Operation. In addition, compared to conventional needle bar drives the achievable embroidery speed increases and the energy consumption lowered. This applies both in training the electric direct drive as a reluctance motor as well as in the design as permanent magnet excited Linear motor.
In bevorzugter Ausgestaltung ist der Läufer des elektrischen Direktantriebs zylindrisch ausgebildet und in einem hohlzylindrischen Stator angeordnet. Die Symmetrieachse des Läufers und des Stators stimmt dabei mit der Symmetrieachse der Nadelstange überein. Der Läufer ist vorzugsweise mit mehreren ringförmigen Permanentmagneten bestückt, die mit bestrombaren Statorwicklungen zusammenwirken. Die Permanentmagnete des Läufers, welche ebenso wie die Wicklungen des Stators symmetrisch zur durch die Nadelstange vorgegebenen Geraden angeordnet sind, sind auf einem starr mit der Nadelstange verbunden Halteelement befestigt. In stabiler und zugleich leichter Bauweise ist dieses Halteelement vorzugsweise hohlzylindrisch ausgebildet. In besonders bevorzugter Ausgestaltung ist die Wandung des Halteelements durchbrochen, insbesondere in Form einer Lochung.In Preferred embodiment is the rotor of the electric direct drive cylindrical and arranged in a hollow cylindrical stator. The symmetry axis of the runner and the stator coincides with the axis of symmetry of the needle bar. The runner is preferably equipped with a plurality of annular permanent magnets, the interact with energizable stator windings. The permanent magnets the runner, which as well as the windings of the stator symmetrical to the needle bar are arranged predetermined straight lines are on one rigidly connected to the needle bar holding element attached. In stable and at the same time light construction, this holding element is preferably hollow cylindrical. In a particularly preferred embodiment the wall of the retaining element is broken, in particular in Shape of a perforation.
