防止叠绕的方法和卷绕交叉卷绕筒子的装置
Abstract:
本发明涉及防止叠绕的方法和卷绕交叉卷绕筒子的装置，交叉卷绕筒子通过用于导纱的具有往复螺纹槽(9)的驱动滚筒(3)驱动，其中，通过在反复防止叠绕循环中加速和减速驱动滚筒(3)在驱动滚筒(3)和交叉卷绕筒子(2)之间产生转差率(12)。根据本发明，对驱动滚筒(3)的最大转速和接下来的交叉卷绕筒子(2)的最大转速之间的第一持续时间(Δt)和第二持续时间进行检测，第二持续时间对应于防止叠绕循环′内的另一函数部分的持续时间或者对应于函数部分持续时间的总和。由第一持续时间和第二持续时间构成商数，驱动滚筒(3)的加速阶段根据对商数与至少一个参考值所作的比较被进行调整。本发明还涉及执行所述方法的装置。
Abstract(English):

The method involves generating an alternating slip by acceleration and deceleration between a drive drum (3) and a cross-wound bobbin (2). The driving drum is formed with a spiraled groove (9). Maximum speed of the drive drum and rotational speed of the cross-wound bobbin are recorded according to two function portions. Ratio of two time periods is determined. An acceleration phase of the drive drum is adjusted according to comparison of quotient with a reference value. A braking power is applied in a motor (7) for delaying the drive drum. An independent claim is also included for a device for wrapping a cross-wound bobbin.
