Problems solved by technology

However, as you increase the number of turns you sew around the knot, you increase the amount of suture used
And, the number of circles is many, then prolong the working procedure related to the sewing of the button around the button knot, and reduce its productivity

Embodiment Construction

[0040] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the examples in the drawings.

[0041] Such as figure 1As shown, the sewing machine 1 has a machine part 2, a vertical body part 3 erected on the rear end part of the machine part 2, and a machine part stretched out from the upper part of the vertical body part 3 in parallel with the machine part 2. Head 4, the needle bar 9 that protrudes downward from the front end of the machine head 4, the machine needle 5 installed on the lower end of the needle bar 9, and the machine needle 5 that is arranged in the machine table part 2. A rotary hook (not shown in the figure) and a control device 150 for controlling the sewing machine 1 as a whole.

[0042] The sewing machine 1 is a sewing machine that automatically sews buttons on cloth (that is, an object to be sewn) by the cooperative action of a needle 5 that move...

Abstract

The sewing machine 1 for buttoning is provided with a needle bar stroke mechanism 10 for vertically stroking a needle 5, a needle bar rock mechanism 11 for horizontally rocking the needle 5, a button feed mechanism 30 for longitudinally feeding buttons 200, a cloth feed mechanism 50 for longitudinally feeding cloth 300, a controller 150 for controlling the needle bar stroke mechanism 10, the needle bar rock mechanism 11, the button feed mechanism 30 and the cloth feed mechanism 50. The controller 150 controls the cloth feed mechanism 50 so as to make the pitch Pa in the area A and that Pc in the area C smaller than that Pb in the area B in the buttoning operation.

Description

technical field [0001] The invention relates to a button-wrapping sewing machine for sewing around the button after the button is nailed on the cloth. Background technique [0002] As everyone knows, in the past, there is a button-wrapping sewing machine that wraps a thread around a button thread connected to the button and the cloth after sewing a button on the cloth. Such as Figure 13 As shown, when the button 500 is nailed to the cloth 501, the button 500 is stitched on the cloth 501, and the hole of the button 500 is connected with the cloth 501 with two sets of sewing threads 502 and 503 arranged side by side, and is used when winding the thread. Swivel the machine needle left and right so that it crosses the stitching lines 502, 503 to sew around the knot. The button 500 is placed on the cloth 501 and maintains a protruding state from the cloth 501 . [0003] However, if the number of turns sewn around the knot is small, the stitching around the knot will move, and ...
