Embroidery frame transfer device

Abstract

An embroidery frame transfer device including an embroidery frame holding a workpiece cloth; a carriage supporting the embroidery frame by detachable attachment; a Y-direction transfer mechanism having a first and second ends that moves the carriage in a first direction represented as a Y-direction; an X-direction transfer mechanism that supports the first end from below and that transfers the Y-direction transfer mechanism in a second direction represented as an X-direction orthogonal to the Y-direction; a cover element containing the X-direction transfer mechanism and having an upper surface situated below the Y-direction transfer mechanism; a support structure provided at the second end and that is placed in contact with the upper surface of the cover element to support the Y-direction transfer mechanism; and an elastic element pressing the support structure against the cover element such that the support structure maintains contact with the upper surface of the cover element.

1 . An embroidery frame transfer device, comprising:
 an embroidery frame that holds a workpiece cloth;   a carriage that supports the embroidery frame by detachable attachment;   a Y-direction transfer mechanism that has a first end and a second end and that moves the carriage in a first direction represented as a Y-direction;   an X-direction transfer mechanism that supports the first end of the Y-direction transfer mechanism from below and that transfers the Y-direction transfer mechanism in a second direction represented as an X-direction orthogonal to the Y-direction;   a cover element that contains therein the X-direction transfer mechanism and that has an upper surface situated below the Y-direction transfer mechanism;   a support structure provided at the second end of the Y-direction transfer mechanism and that is placed in contact with the upper surface of the cover element to support the Y-direction transfer mechanism; and   an elastic element that presses the support structure against the cover element such that the support structure maintains contact with the upper surface of the cover element.   
   
   
       2 . The device according to  claim 1 , wherein the elastic element comprises a spring material. 
   
   
       3 . The device according to  claim 1 , wherein the support structure includes a roller that moves by rolling over the upper surface of the cover element. 
   
   
       4 . The device according to  claim 3 , further comprising an annular anti-vibration element that circumferentially covers an outer periphery of the roller. 
   
   
       5 . The device according to  claim 3 , wherein the support structure includes:
 a roller shaft that rotatably supports the roller;   a support frame that supports both ends of the roller shaft;   a first support shaft and a second support shaft each provided on a line of extension from the both ends of the roller shaft to allow the support frame to be moved up and down represented as a Z-direction.   
   
   
       6 . The device according to  claim 5 , wherein centers of the first and the second support shafts and the roller shaft respectively are collinear with an imaginary straight line, and
 wherein the imaginary straight line is parallel to a centroidal line which passes through a centroid of the Y-direction transfer mechanism and which extends in the Y-direction, the imaginary straight line and the centroidal line residing on a Y-Z plane.
