Apparatus for driving shuttle of embroidery machine

Abstract

Disclosed is an apparatus for driving a shuttle of an embroidery machine. The apparatus comprises: a rotation shaft of the shuttle; a lower shaft which transfers a driving power to the rotation shaft, so as to rotate the shuttle; a first magnet provided at the rotation shaft; and a second magnet provided at the lower shaft and corresponding to the first magnet. The first magnet has a hollow cylindrical shape so that the rotation shaft can be inserted through the first magnet while firmly holding the first magnet. The second magnet has a hollow cylindrical shape so that the lower shaft can be inserted through the second magnet while firmly holding the second magnet.

What is claimed is:  
     
         1 . An apparatus for driving a shuttle of an embroidery machine, the apparatus comprising: 
 a rotation shaft of the shuttle;    a lower shaft which transfers a driving power to the rotation shaft, so as to rotate the shuttle;    a first magnet provided at the rotation shaft; and    a second magnet provided at the lower shaft and corresponding to the first magnet.    
     
     
         2 . An apparatus for driving a shuttle of an embroidery machine as claimed in  claim 1 , wherein the first magnet has a hollow cylindrical shape so that the rotation shaft can be inserted through the first magnet while firmly holding the first magnet, and the second magnet has a hollow cylindrical shape so that the lower shaft can be inserted through the second magnet while firmly holding the second magnet.  
     
     
         3 . An apparatus for driving a shuttle of an embroidery machine as claimed in  claim 1 , wherein the first magnet and the second magnet are disposed in directions intersecting each other, and each of the first magnet and the second magnet has a plurality of polar sections, each of which has an individual polarity.  
     
     
         4 . An apparatus for driving a shuttle of an embroidery machine as claimed in  claim 3 , wherein the polar sections are disposed in such a manner that polarities of the polar sections alternate.
