Abstract

Disclosed is a new mechanism and control for high speed and long stroke shuttle motion. A trapezoidal velocity curve is realized by adopting a simple gain scheduling and a learning function which reduces mechanical friction variation by machine or shuttle direction. In addition to this, the ratio of head weight to rotary inertia induces preferable shuttle motion. With these techniques, power consumption can be greatly minimized in a high speed shuttle motion and an acceptable size can be achieved. (Image Omitted) Mechanism
