Abstract: A method and apparatus for electronically gearing the sewing parts of a sewing machine is disclosed. More particularly, it relates to electronically gearing a bobbin (22) to a needle (12) through mechanical linkages and drive shafts. Servo motors (28, 30) provide torque to the needle, bobbin, and various other sewing parts of the sewing machine which reuqire concerted movement. A computer (202) uses servo motor positional information to calculate motion commands that are sent to the needle and bobbin servo motors, thereby enabling electronic gearing of the bobbin to the needle so that each moves substantially in unison. Motion commands sent to servo motors attached to various other sewing parts of the sewing machine are based on servo motor positional information to enable the sewing parts to move in concert with the needle and bobbin. Servo motors move the fabric in two dimensions during stitching, and each move of the fabric is calculated to consume the maximum amount of time available between stitches in order to dampen acceleration and deceleration of sewing parts and eliminate problems associated with machine jerk.

Abstract translation: 公开了一种用于电子传动装置的缝纫机的缝制部分的方法和装置。 更具体地说，它涉及一种电子传动装置的绕线管（22）通过机械联动装置和驱动轴的针（12）。 伺服电机（28,30）提供的扭矩到针，线轴，和缝纫机，其reuqire协同运动的各种其它的缝线部分。 计算机（202）使用伺服电动机位置信息来计算发送到针筒和伺服伺服电动机的运动命令，从而使线轴对针的电子齿轮传动能够基本上均匀地移动。 发送到连接到缝纫机各种其他缝纫部件的伺服电机的运动命令基于伺服电机的位置信息，以使缝纫部件能够与针和线轴一起移动。 伺服电机在缝合过程中将织物两维移动，并计算织物的每次移动，以消除针脚之间的最大可用时间，以抑制缝纫零件的加速和减速，并消除与机械冲击相关的问题。
