s3: when the tension of the yarn changes, the value in the database is compared according to the elastic value sensed by the force sensor (51) to obtain the position change value of the corresponding adjusting roller (9), and the position of the adjusting roller (9) is adjusted through the adjusting motor (12) to enable the elastic member (6) to return to the elastic value when the yarn runs stably.
S4: if the elasticity value sensed by the force sensor (51) in the database is empty, the position of the adjusting roller (9) is determined by calculation according to the elasticity value sensed by the measuring force sensor (51), and once the elasticity value sensed by the force sensor (51) is a value in the database, the operation is continued according to S3.
9. The reciprocating numerical control cored yarn package tension control method of claim 8, wherein the method of obtaining the database comprises the steps of:
s1: the tension control device is used as a pay-off section end, a wire outlet end simulates a winding and laying environment, and the induction value range M of the force sensor (51) during stable wire outlet is recorded;
s2, the outlet end simulation environment at least comprises the working conditions of stable laying, stable winding, core yarn line changing, laying and winding and yarn splicing, and the induction value G of the force sensor (51) under the working conditions is recordednForming a working condition elasticity value library, and simultaneously recording the induction value G of the corresponding force sensor (51) by uniformly increasing and decreasing the wire take-up forcenForming a theoretical elasticity value library;
s3, changing the position of the adjusting roller by driving the adjusting motor to change the tension of the core yarn, returning the sensing value range of the force sensor (51) to the stable state, and recording the distance value W of the distance sensor at the same timen；
S4, detecting the induction value G of the force sensornDistance value W corresponding to distance sensornAnd forming a database.
