摘要： A sewing system serves for sewing seams which the multi-dimensionally in space. A needle-bar upper part of a sewing head is mounted so as to be pivotable in a driven manner about a needle-bar longitudinal axis. A gripper lower part is mounted so as to be pivotable in a driven manner, and in a manner synchronous with the needle-bar upper part, about the needle-bar longitudinal axis, in the sewing-head lower part. Motor components for driving the movement of a needle bar, for pivoting the needle-bar upper part, for driving a gripper in a manner synchronous with the needle bar and for pivoting the gripper lower part are disposed outside the needle-bar upper part and outside the gripper lower part. Parts to be sewn that are topographically non-uniform are also rendered accessible.

摘要： A sewing system comprises a sewing machine, a camera that captures an image of a reference position for sewing, a robot arm that holds the sewing machine and the camera, and a controller. The controller controls operations of forming a first stitch position that results from stitching of the sewing machine, and forming a second stitch position that results from stitching of the sewing machine after rotating the sewing machine at a prescribed angle about a rotation axis that passes through a needle center position stored by the controller. The controller further performs calibration processing that calibrates the needle center position stored by the controller, based on each position of the first stitch position and the second stitch position within image capture ranges of capture images that are obtained by capturing images of the first stitch position and the second stitch position using the camera.

摘要： A driving mechanism for a sewing machine includes a rotatable shaft coupled to one or more needles for moving the needles upward and downward in a reciprocating action. A rotary looper is rotatably secured to the sewing machine at a vertical axle and is coupled to the shaft for allowing the shaft to actuate the needles and the rotary looper simultaneously. A rod is vertically secured in the sewing machine and coupled to the rotary looper for rotating the rotary looper. Two bevel gears are secured to the rod and the shaft for allowing the shaft to rotate the vertical rod.

摘要： A looper drive mechanism for a sewing machine includes: two loopers; looper drive shafts for driving the loopers; a main shaft extending across one plane transverse to the looper drive shafts; and torque transmission units for transmitting rotation of the main shaft to the looper drive shafts. The transmission units include: two slant grooved cams fixed to the main shaft and having grooves each extending through a full circumference and slanting relative to the main shaft; U-shaped followers each having two rollers, each of the rollers being supported by the looper drive shaft and rotating about its own axis within the groove of the slant grooved cams; and connection pins for pivotally mounting the U-shaped followers on the looper drive shafts so that the U-shaped followers are not rotatable in a direction in parallel with a line connecting the two rollers with each other but rotatable in a direction perpendicular to the line connecting the two rollers with each other.
