Abstract

PURPOSE:To form series of stitches to perfect stitches by interlocking a needle bar drive unit with a case drive unit by a mechanical means and rotating a needle and a case synchronously with the feeding of a cloth pressing means to the same direction and by the same rotation quantity. CONSTITUTION:A motor 24 rotates a needle bar drive unit 6 and a case drive unit 28 by centering around the shaft of a needle bar 3 synchronously with the two dimensional movement of a processing fabric. The rotation direction and the rotation amount of the synchronous rotation of a case 30 and the needle bar 3 based on the rotation of the motor 24 correspond to the feeding direction and the feeding amount of the processing fabric fed by a X-Y table 19. Accord ingly, when the feeding direction of the processing fabric is changed, a needle 7 and the case 30 are rotated correspondingly thereto. As a result, the relative positional relation between the needle 7 and the case 30 relative to the feeding direction of the processing fabric is usually constantly maintained. All stitches formed on the processing fabric by a needle thread and a looper thread are perfectly formed.

[Problems to be Solved by the Invention] As mentioned above, in conventional automatic pattern sewing machines, the work cloth is transported two-dimensionally in front, back, left and right by the feed device, whereas the needle and hook are fixed and always in use. It's in a certain direction. Therefore, a part-efto-stitch or a hit-stitch seam is formed depending on which side of the needle the exit of the thread threaded through the needle or the thread exiting from the bobbin is with respect to the needle. Normally, the hitsuchi stitch is inferior in appearance to the part-efto stitch and is considered unsuitable for various decorative stitches. Therefore, when decorative stitching or the like is performed using such a conventional automatic sewing machine, there is a problem in that the quality of the product deteriorates.

[Scope of Claims] A needle that is attached to a needle bar and moves reciprocatingly in the vertical direction by passing the upper thread through the needle hole, a needle bar drive unit that rotates the needle around an axis of the reciprocating motion, and the needle A presser foot is placed below the workpiece cloth and moves two-dimensionally on a horizontal plane together with the workpiece cloth while holding the workpiece cloth. The presser foot rotates in synchronization with the reciprocating movement of the needle and works together with the upper thread to stitch the workpiece cloth. a hook for accommodating a bobbin thread that forms the needle, and a hook drive unit that rotates the hook around an axis of reciprocating movement of the needle, and the needle bar drive unit and the hook drive unit are connected by mechanical means. An automatic sewing machine characterized in that the needle and hook are rotated in the same direction and by the same amount in synchronization with the movement of the presser foot.
