US 12,312,200 B2 · Method and system for detecting a traverse winding defect

Abstract

The invention relates to a method for detecting a traverse winding defect when winding a link (L) on a spool (1) rotatably driven about a longitudinal axis (X), the link (L) being alternately translationally guided relative to the spool (1) by a guide pulley (2) along said longitudinal axis (X) between two reversal positions, comprising: measuring the position of the guide pulley (2) relative to the spool (1) along the longitudinal axis (X) over time, measuring the position (P2) of a regulation device for regulating the advance speed of the link on the guide pulley over time, from said measurements, determining a deviation between the position (P3) of the regulation device and a reference position (P3r) at each reversal position (Pi1, Pi2), and from said deviation, detecting the formation of a hollow or bump in the winding.

A method for detecting a traverse winding defect when winding a link on a spool rotatably driven about a longitudinal axis, the link being alternately translationally guided relative to the spool by a guide pulley along said longitudinal axis between two reversal positions, comprising:

measuring the position of the guide pulley relative to the spool along the longitudinal axis over time;
measuring the position of a regulation device for regulating an advance speed of the link on the guide pulley over time, the measuring being carried out in a measurement window encompassing each reversal position;
from said measurements, determining a deviation between a position of the regulation device and a reference position at each reversal position;
and
from said deviation, detecting the formation of a hollow or bump in the winding,
wherein minimum and maximum positions of the regulation device are determined in each measurement window and deviations between each respective minimum or maximum position and the reference position of the regulation device are calculated.
