摘 要:松式络筒机张力的稳定是保证筒纱染色均匀的前提,因此,研究分析松式络筒时张力波动的原因并寻求解决的办法具有现实的意义。通过对传感器蠕变误差、设备的传动振动、纱结突变和摩擦静电等影响络筒张力波动的诸多因素进行逐一分析,提出了针对不同影响因素的特征,进行在线测量数据的动态补偿处理方法,并将该方法在BD-S10松式络筒机上进行了应用实践,纱线张力测量精度得到提高。结合张力控制技术的应用,BD-S10松式络筒机取得了良好的张力控制效果。

Abstract:Maintaining tension stability of soft-cone winder is the premise of the coloring uniformity for cone yarn. Because of this, studying the reason of tension fluctuation in soft-cone winder and finding out the solution have practical significance. many factors influencing tension fluctuation are analyzed one by one in this paper, including creep error from sensor, vibration of the equipment, mutation of yarn knot and frictional static. Besides, the dynamic compensation method for online measurement data is proposed for features of different factors. The method is applied on BD-S10 soft-cone winder, and the measurement accuracy has been improved. Combining with tension control technology, BD-S10 soft-cone winder has gained very good tension control effect.

Key words:soft-cone winder; single yarn tension; dynamic measurement; data compensation

纱线张力稳定、卷绕密度均匀既是松式络筒的质量要求,也是保证筒纱染色质量的前提。而在松式络筒卷装过程中,纱线的张力降低,当张力减小到一定程度,容易形成松弛,产生卷装起皱。松弛造成纱线间摩擦力减小,严重时可能造成纱线沿轴向向外移出,出现胀边。特别是供筒子染色用的纱线,筒子卷绕的松紧度、卷装密度的均匀性,是卷装筒子质量的重要指标,直接影响后期染色的均匀性。纱线的张力控制是各种精密卷绕络筒机必备环节[1]。

1 张力测量原理

张力测量是张力控制的前提,电阻应变式传感器是纺纱、络筒、整经及织造中的单纱张力测量应用非常广泛的一种传感器[2],它的基本结构是由粘贴于弹性体变形敏感区的电阻应变片组成一个电桥,从而得到与被测重量作用于该弹性体的力成比例的电压输出信号。……
