Embodiment Construction

[0054] Hereinafter, embodiments of the sewing machine according to the present invention will be described with reference to the drawings.

[0055] figure 1 It is a schematic side view of the sewing machine which concerns on this embodiment.

[0056] like figure 1 As shown, the sewing machine 10 according to the present embodiment includes: a sewing machine base part 11 ; a vertical body part 12 provided upright at the rear of the sewing machine base part 11 ; and an arm part 13 extending forward from the vertical body part 12 And set.

[0057] A sewing mechanism 17 to be described later is provided on the sewing machine head 14 serving as the distal end portion of the arm portion 13 , and the sewing mechanism 17 includes a needle bar 16 to which a sewing needle 15 is attached. The sewing mechanism 17 moves the needle bar 16 up and down by the rotational force of the main shaft (not shown) rotated by the driving motor (not shown), whereby the sewing needle 15 holding the up...

Abstract

The present invention provides a sewing machine capable of adjusting sewing positions so that sewing pitches do not stand out. The control part (50) performs the following processing: the sewing pitch actual measurement process, based on the detection signals of the respective ends of the collar (100) of the first sensor (31) and the second sensor (32), for the collar (100) ) is actually measured for the sewing pitch of the stitch (102); the correction pitch calculation process is performed on the line from the needle entry position (NP) to the direction change point (102a) at the corner (101) that changes the sewing direction. The sewing pitch of the trace (102) is calculated with respect to the actual measurement sewing pitch of the stitches (102) that is measured, the correction pitch that gradually becomes smaller, or the correction pitch that becomes larger gradually; and feed adjustment processing, the cloth The feed mechanism (22) is adjusted to form the stitches (102) at the calculated correct pitch.

Description

technical field [0001] The present invention relates to a sewing machine for sewing a to-be-sewn product. Background technique [0002] For example, a sewing machine is known that calculates the distance between the current position and the sewing end position when sewing the stitch of the collar, and corrects the sewing pitch so that the sewing end position is at the sewing end position. The sewing is completed (for example, refer to Patent Documents 1 and 2). [0003] Patent Document 1: Japanese Patent Laid-Open No. 58-46989 [0004] Patent Document 2: Japanese Patent Laid-Open No. 61-217198 [0005] In addition, when the sewing pitch from the predetermined position to the sewing end position is averaged or the sewing pitch at the last stitch is adjusted in order to end sewing at the sewing end position, the same The changed parts between the pitches become prominent, and the aesthetics deteriorates. SUMMARY OF THE INVENTION [0006] The present invention has been ma...
