Embodiment Construction
[0113] A hem seam sewing machine according to an embodiment of the present invention will be described with reference to the drawings.
[0114] Such as figure 1 etc., the side seam sewing machine 100 according to one embodiment of the present invention includes: a stand 1, a knee switch plate 2, a workbench 10, a sewing machine head 20, a cloth holding member conveying device 30, a cloth end holding member 40, and control devices, etc.
[0115] In the figure, three orthogonal axes X-Y-Z are shown. Among them, the orthogonal two-axis XY corresponds to the orthogonal two-axis coordinates that define the position on the table 10 . The X-axis is an axis parallel to the sewing direction, that is, the direction in which the cloth is conveyed during sewing, and the forward direction of the sewing machine head 20 is assumed to be positive. The Y-axis is an axis perpendicular to the X-axis, and when viewed from the sewing machine head 20, the direction toward the table 10 is positiv...

A side seam sewing machine maintains a state that a joint end portion between a sleeve and a clothes body bends towards a specific direction in high precision, and cloth conveying is performed, and the side seam sewing machine sews sides from the sleeve to the clothes body in high precision. The side seam sewing machine comprises a workbenck, a sewing machine head, and a cloth pressing piece conveying device. The cloth pressing piece conveying device is provided with a cloth pressing piece and a cloth moves on the workbench. The cloth pressing piece presses the cloth on the workbench, and a cloth carrying surface along the workbench moves towards a sewing direction. The cloth pressing piece is provided with a main cloth pressing piece and an auxiliary cloth pressing piece. The main cloth pressing piece is formed by a strip component which presses from an end of a cloth on the sewing direction to an end. The auxiliary cloth pressing piece is attached to the main cloth pressing piece and moves with the main cloth pressing piece. Relative to a configuration range of the cloth conveying component of the sewing machine head, specified on a Y-axis, a front end extends out, and is arranged to withdraw to the configuration range of the main cloth pressing piece. When the cloth is conveyed by the cloth pressing piece conveying device, the auxiliary cloth pressing piece extends out and presses the end of a joint.
Description
technical field [0001] The present invention relates to a side seam sewing machine, which keeps the seam line of the armpit of the body with sleeves sewn first and the seam line extending from the armpit of the sleeve to the cuff direction on a straight line and performs continuous locking. side seam. Background technique [0002] At present, as described in Patent Document 1, the following operation is performed, that is, the cloth holding member (guide rail in this document) is lowered along the seam line to the cloth placed on the table and held, and the cloth holding member is horizontal. To move the fabric so that the fabric slides on the table and is transported to the needle drop position of the sewing machine. [0003] When sewing clothes with sleeves such as shirts, sometimes after sewing the front body and the back body according to the line on the shoulders, the sleeves are sewn to the front body and the back body, and thereafter, the armpits of the body are sewn...
