Abstract
The microswitch 6 is turned on when the foldable Y arm 1 is in the operative position for embroidery stitching and is turned off when the Y arm 1 is not in the operative position, and the X-Y motor drive prohibition device 87 is responsive to the on-signal of the microswitch 6 to withdraw the prohibition of driving and to drive the X-and Y-drive motors 15, 46.
Claims7
An embroidery sewing machine for stitching embroidery patterns by moving a holder for holding a work to be stitched and having an X-direction drive mechanism for moving said holder in an X-direction that is in a width direction of a sewing machine body and a Y-direction drive mechanism for moving said holder in a Y-direction that is in a depth direction of the sewing machine body,
- wherein said Y-direction drive mechanism may be turned around an axis provided on the body of the sewing machine between an operative position where said Y-direction drive mechanism is extended in the Y-direction and embroidery operation is possible and an accommodating position where said Y-direction drive mechanism is oriented along the X-direction, the embroidery sewing machine comprising:
- a prohibition device for prohibiting under normal conditions at least said X-direction drive mechanism and said Y-direction drive mechanism from driving,
- a signal device for providing a signal when said Y-direction drive mechanism is in said operative position and embroidery operation is possible, and
- a device for withdrawing said prohibition of the driving of the X-direction drive mechanism and the Y-direction drive mechanism when said signal is provided from said signal device.
An embroidery sewing machine for stitching embroidery patterns by moving a holder holding a work to be stitched and having an X-direction drive mechanism for moving said holder in X-direction that is in a width direction of a machine body and a Y-direction drive mechanism for moving said holder in a Y-direction that is in a depth direction of the machine body, wherein said Y-direction drive mechanism may be turned around an axis provided on the body of the sewing machine between an operative position where said Y-direction drive mechanism is extended in the Y-direction and embroidery operation is possible and an accommodating position where said Y-direction drive mechanism is oriented along the X-direction, the embroidery sewing machine comprising:
- a prohibition device for prohibiting in under normal conditions at least said X-direction drive mechanism and said Y-direction drive mechanism from driving,
- a signal device for providing a signal when said Y-direction drive mechanism is in said operative position and embroidery operation is possible, and
- a device for withdrawing said prohibition of the driving of the X-direction drive mechanism and the Y-direction drive mechanism when said signal is provided from said signal device,
- a locking device for locking the turning of the Y-direction drive mechanism when the Y-direction drive mechanism is at least in the operative position,
- a device for overriding the locking device of the Y-direction drive mechanism, wherein
- said signal device provides the signal indicating embroidery is possible when said Y-direction drive mechanism is in said operative position and the turning motion is locked by said locking device.
