摘要： A sensing system for detecting motion of a bobbin used in a chain stitch type sewing machine using a needle on one side of a textile workpiece and a rotary bobbin positioned on an opposing side of the textile workpiece includes the bobbin being held in a bobbin case having a side panel forming an aperture. The rotary bobbin has a side surface with arcuate regions around a perimeter of the side surface. In addition, the sensing system includes the first and second optical sensors aligned to detect the presence of the first or second bobbin surface. The sensing system further includes a controller adapted to receive signals from the first and second optical sensors related to the presence of the first or second bobbin surface in the first or second regions and interpret the signals to provide the detecting motion of the bobbin.

摘要： Dual-motor sewing machine with automatic timing adjustment. In some embodiments, a sewing machine may include a frame, a needle bar configured to have a needle, a first motor configured to cause the needle bar to linearly reciprocate the needle with respect to the frame and into and out of a fabric, a first sensor configured to continuously sense a current position of the needle, a bobbin hook configured to function in connection with a bobbin, a second motor configured to cause the bobbin hook to rotate with respect to the frame, a second sensor configured to continuously sense a current position of the bobbin hook, and one or more motor controllers. The one or more motor controllers may be configured, based on the current positions sensed by the first sensor and the second sensor, to continuously and automatically adjust and synchronize timing of the first motor and/or the second motor.

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 hollow pipe joint structure for a sewing machine includes a first hollow pipe, a second hollow pipe and an elastic member. The elastic member is sleeved onto the first hollow pipe and the second hollow pipe, and elastically squeezes against the first outer surface and the second outer surface of the first and second hollow pipes, respectively, to pull the first and second hollow pipes against each other, which makes assembly of the hollow pipes easier, quicker and no frequent maintenance is required.

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.
