摘要： The invention relates to a method of contactless optical detection of yarn (1) at a workstation of a yarn (1) manufacturing textile machine, in which the yarn (1) moves in a sensing slot (92) between at least one source (90) of radiation and at least one optical sensor means (91) of radiation comprising at least one row of radiation sensitive elements arranged next to each other, whereby shading of the individual radiation sensitive elements by the moving yarn (1) is monitored and the state of the yarn (1) is evaluated on the basis of this monitoring process. The position P of the yarn (1) and/or the time course of the position P of the yarn (1) in the sensing slot (92) is monitored and evaluated, thereby detecting a change ΔP in the position P and/or the time course of the change ΔP in the position P of the yarn (1) corresponding to a yarn (1) break and upon detecting the break before the broken yarn (1) end passes through the sensing slot (92), a signal to stop the workstation is issued. The invention also relates to an optical sensor of yarn and a textile machine for performing the present invention.

摘要： The apparatus and methods disclosed herein are directed to detecting the presence of a whipping tail when using a fiber winding system (10) to wind a fiber (70) onto a rotating spool (20). The fiber (70) is guided onto the rotating spool (20) through a containment region (80) between the spool (20) and a whip shield (100) to create the wound fiber. The whipping tail (72W) outwardly extends from the wound fiber (70) and periodically or quasi-periodically passes through a light beam (152) to create a series intensity dips in the light beam, thereby forming a modulated light beam. The modulated light beam (152M) is converted into a digital electrical signal (SD) made up of electrical pulses (PV) having a timing defined by the intensity dips (Dl). The measured timing of the electrical pulses (PV) is compared to an estimated timing based on the rotating spool (20) to ascertain the presence of a whipping tail (72W).

摘要： This invention provides an auto yarn cutter for spinning frame. There is a piezoelectric transducer, which can transform the nonelectric signal of yarn breakage into an electric signal, by virtue of an amplifying circuit the electric signal can be amplified, and then the amplified signal can activate an electromagnetic driven mechanism, because the yarn passed through the eye made by piezoelectric ceramic, hence when one or more of the yarns break(s), the pressure applied to the eye disappears and produces the signal, then the driven mechanism can cut the residual yarns, to ensure the quality of the yarn produced. By using of the auto yarn cutter of the invention, the yarns can be cut before entering the spindle, so there is no need to stop the spindle, all the spindles of the spinning frame can be driven by a same motor. The auto yarn cutter of the invention can be used in a winder, a double twister, a double winder, a grooved drum spinning frame, and the like.

摘要： A method and an apparatus for measuring the position where a running thread breaks. Breakage of a thread is detected based on a tension signal outputted from a tension detector adapted for monitoring the running thread and disposed in a reference position. Then the end of broken thread passing through the reference position is detected. The breaking position of the thread is calculated the time after the breakage occurs until the end of broken thread passes through the reference position. The time point when the thread breaks is stored as time point when the tension signal has a peak value and/or the time point when the tension signal begins to decrease from the normal tension signal level. The time point when the end of thread passes through the reference position is stored as the time point when the tension signal becomes below a lower limit value and/or the time point when natural vibration begins.
