Active feedback levelwinding system

摘要

An active feedback levelwind apparatus and method for winding cable on a drum has a rotary encoder providing signals representative of drum rotation and a shuttle adjacent the drum receives, bidirectionally moves and wraps the cable on the drum. An outboard sensor assembly on the shuttle has an angular sensor providing signals representative of the angle of extension of an outboard extending portion of the cable. An inboard sensor assembly on the shuttle has an inboard sensor providing signals representative of the angle of extension of an inboard extending portion of the cable. A stepper motor coupled to a computer system bidirectionally displaces the shuttle and cable in response to the rotation signals, outboard angular signals, inboard angular signals and limit signals to smoothly wind the cable. Error position feedback signals from the computer system create corrective displacements for the shuttle to smoothly wind cables of varying widths.
