The present invention provides a zigzag seam sewing machine capable of more accurately detecting the positions of the end edge parts of two objects to be sewn, the machine comprising: a transverse feeding mechanism for moving each object to be sewn along the needle swinging direction of a sewing needle at the upstream side of the feeding direction of the object to be sewn relative to a needle falling position; a position detection part used for detecting the positions, in the needle swinging direction, of the end edge parts of the two sewn objects which are arranged on the conveying face on the upstream side in the feeding direction and located on one side and the other side in the needle swinging direction respectively; and a control device for controlling the transverse feeding mechanism based on the detection of the position detection part so that the end edge parts approach or abut against each other, wherein the position detection part is provided with a light source for irradiating linear detection light along the needle swinging direction in a manner of crossing the two sewn objects; a shooting part that shoots the detection light from the direction different from the irradiation direction of the light source. The zigzag seam sewing machine is provided with a height difference forming part for forming the height difference between one sewn object and the other sewn object at the irradiation position of the detection light on the conveying surface.
Description
technical field [0001] The present invention relates to a zigzag sewing machine which performs sewing for joining a sewn object to the sewn object. Background technique [0002] In order to join the edge portion of the object to be sewn and the end edge portion of the object to be sewn, sewing is performed by a zigzag sewing machine in which the needle swings left and right with respect to the direction of sewing. [0003] And, in the conventional sewing, for example, when the shape of the edge portion of one to-be-sewn object and the edge portion of the other-side to-be-sewn object are inconsistent, the operator makes the edge portion manually. Butt against the edge portion and transport each to-be-sewn object to the needle drop position (for example, refer to Patent Documents 1 and 2). [0004] Patent Document 1: Japanese Patent Publication No. 55-48838 [0005] Patent Document 2: Japanese Patent Laid-Open No. 2003-38877 [0006] However, the operation of butting the ed...
