Before the device is started, acquiring a margin parameter change value E 1 of the corresponding cord when the cord is wound into a take-up pulley for X length;
the controller is specifically configured to:
Comparing the standard margin parameter a 0 with the edge margin parameter a 1;
according to the comparison result of the A 0 and the A 1, adjusting the target reversing time T of the traverse unit moving from the preset position to the target reversing position;
the controller is further used for calculating preset reversing time T 0 when the wire arranging device moves from the preset position to the edge of the wire take-up wheel according to the L 0 and the pre-acquired moving speed V of the wire arranging device;
The controller is further configured to adjust the target commutation time T according to the following equation:
T＝(A1-A0)*π*D1*2/X*E1+T0
Wherein A 1 is an edge margin parameter, A 0 is a standard margin parameter, D 1 is the diameter of the cord, and T 0 is a preset commutation time.
4. the traverse apparatus of claim 3, wherein the sensor is further configured to:
and after the wire arranger reaches a preset position, acquiring the margin parameters of the cord thread at preset time intervals, calculating the average value of all the margin parameters when the acquired margin parameters reach a preset number, acquiring the edge margin parameter A 1, and sending the edge margin parameter A 1 to the controller.
