Embodiment approach 1

[0045] (The composition of the button sewing machine)

[0046] FIG. 1 is a diagram showing a schematic configuration of the appearance of the button sewing machine 1 together with a block diagram of a control circuit, and FIG. 2 is a perspective view showing a portion of the button sewing machine 1 that performs button sewing. The button sewing machine 1 has a bottom plate 11 , a vertical cylinder 12 standing upright on the bottom plate 11 , and an arm 13 extending from the vertical cylinder 12 to face the bottom plate 11 . In the following description, the front-rear direction and the up-down direction of the button sewing machine 1 are respectively Y-axis direction and Z-axis direction as shown in FIG. 1 . In addition, the direction perpendicular to the paper of FIG. 1 is the left-right direction (X-axis direction), the front side of the paper is the right side, and the back side of the paper is the left side.

[0047] The button sewing machine 1 is provided with the front ...

Embodiment approach 2

[0100] Hereinafter, the button sewing machine according to Embodiment 2 will be described. In addition, since the difference between the button sewing machine of the second embodiment and the button sewing machine of the first embodiment is the configuration of the tongue piece and the reinforcing cloth holding member, these parts will be described, and the other common points will be given the same reference numerals and omitted. illustrate.

[0101] (tongue)

[0102] As shown in FIG. 5 , the tongue piece 40 is a member bent in an arm shape, and its base end is rotatably supported on the lower end of the bottom plate 11 on the front end side around an axis in the X-axis direction.

[0103] In addition, the front end portion 40a of the tongue piece 40 keeps the cloth to be sewn on the button in a curved state during the blind seam, and at the same time, when the blind seam is formed and the thread knot is sewn, the root yarn formed by the blind seam The knot head holds the c...

Embodiment approach 3

[0126] Hereinafter, a button sewing machine according to Embodiment 3 will be described. The difference between the button attaching machine of the third embodiment and the button attaching machine of the first embodiment is the configuration of the tongue and the reinforcing cloth holding member, so these parts will be described, and the other common points will be given the same reference numerals and their description will be omitted.

[0127] (tongue)

[0128] As shown in FIG. 6 , the tongue piece 50 is a member bent in an arm shape, and its base end is rotatably supported by the lower end on the front end side of the bottom plate 11 around the axis in the X-axis direction.

[0129] In addition, when the front end portion 50a of the tongue piece 50 is blind stitching, the cloth to be sewn into the button is kept in a curved state, and at the same time, when the blind stitching is performed and the thread knot is sewn, the root yarn formed by the blind stitching The knot h...

Abstract

A chain stitch button sewing machine, comprising: a button holding mechanism for holding a button (B); a cloth holding member (30), which is under the button (B) and extends from the rear to the sewing needle ( 15) The front end (30a) in the vicinity of the up and down movement path holds the object to be sewn (W) in a hemmed state; the cloth moving mechanism is positioned up and down with the sewing needle (15) relative to the cloth holding member (30) relative movement in the direction where the direction of motion intersects; catch the sewing thread from the descending sewing needle (15) to form the yarn bending wheel of the loop, and the sewing needle (15) is positioned between the sewn object (W) held by the cloth holding member (30) The hemming part moves up and down to sew the button held by the button holding mechanism. A reinforcing cloth holding member (3) is provided on the cloth holding member (30) so that the reinforcing cloth (C) is positioned on the sewn object (W ), and hold the reinforcement cloth between the object to be sewn and the front end in a state of passing through the hemming of the front end together with the object to be sewn.

Description

technical field [0001] The invention relates to a chain stitch button sewing machine for sewing buttons on cloth. Background technique [0002] In the past, for example, as described in Patent Document 1, it is known that a sewn object is kept under a button in a hemmed state, and a sewing needle moves up and down on the buttonhole and the hemmed part to form a so-called dark hole. This is a chain stitch button sewing machine that wraps a thread knot around the root yarn forming the concealed stitch (knot sewing) while stitching and sewing a button on the object to be sewn. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-164679 [0004] However, the shirt has what is called a button-down shirt.
