Abstract
A stitching system is configured to stitch through decorative skins with a molded seam recess representing a seam and includes a sewing machine, an image acquisition mechanism, a controller, and a rotation mechanism. The sewing machine is rotatable with respect to a support table, and includes a sewing head to receive a sewing needle and a sewing foot to selectively engage the skin. The image acquisition mechanism produces an image of the seam recess with respect to the sewing head/needle(s). The controller determines the difference between the actual recess location and a predetermined desired recess location. Based on this difference, the controller determines a sewing machine rotation angle and orientation to reduce the difference to zero, and then produces a corresponding adjustment signal that drives the rotation mechanism. A robot can move either the sewing machine or the workpiece, and still use the herein-described real time steering control.
