一种用于纺织机械的牵伸系统的牵伸控制方法,以及一种纺织机械
摘要：
提供一种用于纺织机械(1)中牵伸系统(5)的牵伸控制方法，其中，对于输入牵伸系统(5)的纤维条(FGzu)的连续片段(AB1，...，ABn-2，ABn-1，ABn)，牵伸系统(5)上游的喂入传感器单元(4)获得每个片段的单位长度的重量的测量值(MLM1，...，MLMn-2，MLMn-1，MLMn)；为了匀整输入纤维条(FGzu)单位长度的重量，一旦与所述某个测量值(MLM1)相关的片段(AB1)到达由指定数值(RP)指定的控制动作点(REP)，在所述测量值(MLM1)的基础上，对牵伸系统(5)的牵伸(V)进行控制调节；在纺织机械(1)生产阶段，对用于控制动作点(REP)的指定数值(RP)进行修正，在那里，指定数值(RP)来自于预先确定的设定值(ERP)和修正值(ΔRP)，同时，修正值(ΔRP)由与输入牵伸系统(5)的纤维条(FGzu)的喂入速度(EG)相关的数值(MEG，GM，GM’，SEG)和与输出牵伸系统(5)的纤维条(FGab)的输出速度(LG)相关的数值(MLG，SLG)确定。同时提供一纺织机械。
摘要（英）：

The present invention provides a drafting controlling method for the drafting system (5) of the textile machinery (1), wherein, for the continuous fragments (AB1, ellipsis, ABn-2, ABn-1, ABn) of the fiber strip (FGzu) of the inputting drafting system (5), the feeding sensor unit (4) at the upriver of the drafting system (5) gets the measured value (MLM1, ellipsis, MLMn-2, MLMn-1, MLMn) of weight at unit length of each fragment; to regulate the weight at unit length of the inputting fiber strip (FGzu) when the fragment (AB1) which is relative to a certain measured value (MLM1) reaches a control action point (REP) assigned by the appointed control value (MLM1), it will do controlling and regulation to the drafting (V) of the drafting system (5) on the basis of the measured value (MLM1); it modifies the appointed value (RP) used to control the action point (REP) in the making process of the textile machinery (1), wherein, the appointed value (RP) is from the predefined setting value (ERP) and corrected value (delta RP), at the same time the corrected value (delta RP) is confirmed by the values (MEG, GM, GM', SEG) relative to the feeding velocity (EG) of the fiber strip (FGzu) of the inputting drafting system (5) and the values (MLG, SLG) relative to the outputting velocity (LG) of the fiber strip (FGab) of the outputting drafting system (5). The invention also provides a textile machinery.
