Anti-interference and anti-shake position servo system of 3-axis overhead crane

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control apparatus for unmanned three-axis overhead crane which is often used in factories or production sites. The present invention relates to a three-axis overhead crane that prevents shaking of a conveyed object in an arbitrary direction generated during movement of a three-axis overhead crane, regardless of the size of a load mass, The position servo apparatus includes a driving motor torque reference display, a non-interference controller, a speed controller, a position controller, and an anti-shake controller. The anti-shake position display includes a girder of a traveling axis and a trolley And the position view including the drive motor torque display and speed controller controls the height of the conveyed object suspended in the direction of the traverse / traverse axis, and as the traverse length of the conveyed object changes, And the gain of the controller is adjusted. Thus, regardless of the size of the load mass 3-axis, so the overhead crane can be prevented movement of the feed water shaking in any direction occurring while, at the same time can be moved quickly and precisely the crane to the desired location, it is effective to increase productivity.
