Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following figures, the same reference signs are used for the same components. For ease of understanding, the scales of the drawings are appropriately changed in scale and some components are omitted.

[0018] Fig. 1 is a partial side view viewed from one side when a skipping mechanism portion for a sewing machine according to the present invention is located at the top dead center position. In FIG. 1 , which shows a part of a sewing machine such as an embroidery sewing machine, a support case 19 is slidably provided in a horizontal direction on a frame 18 provided on an upper case 12 of the sewing machine. A plurality of needle bars 20 are arranged in the support case 19 , and a specific needle bar 20 can be selectively driven by moving the support case 19 along the frame 18 .

[0019] As shown in FIG. 1 , a jumper mechanism unit 10 of a sewing machine such as an...

Abstract

A jump sewing device for a sewing machine is characterized by arresting noise, having simple structure and simplifying motions of the inside thereof in jump-sewing. A jump sewing device for a sewing machine comprises: a sewing shaft capable of rotating; a first delivery device changing rotational motion of the sewing shaft into reciprocal motion and delivering the motion; a needle rod(20) installed a sewing needle(21) and reciprocal-moved by the reciprocal motion of the first delivery device; a second delivery device delivering the reciprocal motion of the needle rod(20); a fabric presser pressing fabric; and a fabric presser guiding rod reciprocal-moved by reciprocal motion delivered by the second delivery device. The jump sewing device is worked by: separating the needle rod(20) from the fabric; stopping the first delivery device to stop the needle rod(20) and the fabric presser guiding rod; and transferring the fabric as proper length.

Description

technical field [0001] The present invention relates to a sewing machine equipped with a jump stitch mechanism, especially an embroidery sewing machine. Background technique [0002] Figure 7 It is a partial side view of an embroidery sewing machine in the prior art. Such as Figure 7 As shown, the jump stitch mechanism part 100 of the embroidery sewing machine includes a needle bar 200 . The front end of the needle bar 200 to which the needle 210 is installed protrudes from the hole of the supporting housing 190 through the gasket 120 . Near the center of the needle bar 200 is provided a needle bar holder 220 equipped with a protrusion 230 . Furthermore, the skipping mechanism part 100 further includes a lifter guide rod 400 arranged parallel to the needle bar 200 , and a lifter 410 is slidably provided on the lifter guide rod 400 . On the side of the lifting body 410 is formed a groove 420 into which the protrusion 230 of the needle bar holder 220 is engaged. Lifting ...
