As shown in Figure 2, spindle 7 is by spindle motor MSP driven in rotation, and the rotating speed of spindle 7 detects by sensor SSP.Yarn carries out side travel by motor MTR as drive source, and the frequency of side travel detects by sensor STR.The rotating speed of touch roll 9 detects by sensor SCR.The detection signal of each sensor SSP, STR, SCR is delivered to for example central processing unit (CPU) of control setup.The rotating speed of each motor MSP, MTR by control setup for example CPU control.
Tension detecting device comprises Sensor section (detector) S1-S6 that is used to measure yarn tension and is used for being tried to achieve by the detection signal of Sensor section S1-S6 output the calculating unit TC of tension force.As shown in Figure 3, each Sensor section S1-S6 comprises an elastic plate 12, a U-shaped contact portion 15 and a cramp bar 13, elastic plate 12 is provided with strain gauge 14, and a side of elastic plate 12 is fixed, U-shaped contact portion 15 can contact with yarn at horizontal point of transition place, and cramp bar 13 is bearing in contact portion 15 on the elastic plate 12.When contact portion 15 contacted also edge horizontal (direction of arrow A) motion with yarn, because a side of elastic plate 12 is fixed, therefore, its opposite side moved (direction of arrow B) with regard to generation and elastic plate 12 produces strains.Each Sensor section S1-S6 sends and the cooresponding detection signal of strain facies, and it is delivered to calculating unit TC.
As shown in Figure 4, calculating unit TC comprises low-pass filter (LPF) 21, traffic pilot (MPX) 20, A/D converter (ADC) 22 and central processing unit (CPU) 24.The frequency component of 1/2 times of the detection signal that LPF21 sends from Sensor section S1-S6 (analog signal) intercepting or multi-fold ADC sampling frequency.MPX20 selects the detection signal by LPF21.ADC22 converts the detection signal that MPX20 selects to digital signal.CPU24 receives the output signal of the sensor STR be used to detect horizontal frequency and the output signal of ADC22.CPU24 accepts the selection of MPX20 by selecting the signal instruction output signal.CPU24 receives the input detection signal from sensor SCR, SSP, and control motor MSP, MTR.

In the horizontal frequency of yarn winding process part omitted fine adjustment so that regulate the shape of thread layers of each rolling P1-P6.For example, in order to regulate winding angle (hand of rotation of reel 11 and the formed angle of yarn coiling direction), can change horizontal frequency.For example, can change horizontal frequency significantly, to avoid taking place so-called banded the coiling, just because the integral multiple that horizontal frequency is the coiling swing circle makes reel for yarn around with the coiling on the part.CPU24 can control horizontal frequency.When the horizontal frequency of change, can discard the data before changing, and utilize change data afterwards to detect tension force, perhaps can utilize data and change data afterwards before changing to detect tension force.
To the tension force that utilize tension detecting device of the present invention to detect yarn be described below.Fig. 7 and 8 shows an embodiment of tension force testing process.Fig. 7 mainly shows the process that the output signal of each Sensor section S1-S6 is sampled.Fig. 8 mainly shows the process of by CPU24 the frequency of detection signal being analyzed and calculated tension force.Sampling and calculating are mainly undertaken by CPU24.In this embodiment, the number of sampling is 128.
As shown in Figure 7, before beginning sampling, to the toggle count device value Nx of MPX20 and samples counter value Nd reset (S10).When toggle count device value Nx be 0,1 ..., 5 o'clock, select Sensor section S1, S2 ..., among the S6 one.These Nx and Nd value are stored in the allied equipment of memory device 24f or CPU24.Because toggle count device value Nx is 0, therefore, CPU24 selects Sensor section S1 and by ADC22 the detection signal that Sensor section S1 exports is converted to digital signal (S12) by MPX20.After being converted to digital signal (S14: be), toggle count device value Nx adds 1 (S16) and MPX20 is outputted to Sensor section S2 (S18).(S20: not), the detection signal that Sensor section S2-S6 is exported is not converted to digital signal in the same way when toggle count device value Nx reaches 6.
When toggle count device value Nx reaches 6 (S20: be),, therefore, toggle count device value Nx is resetted (S22) and samples counter value Nd is added 1 (S24) because the detection signal of Sensor section S1-S6 is converted to digital signal.(S30: not), proceed sampling when Counter Value Nd does not reach 128.When (S30: be), owing to finished 128 samplings, therefore, Counter Value Nd resets (S32) when Counter Value Nd reaches 128, and the completed parameter F LUG of expression sampling is updated to " 1 " (S34).Repeat same process and proceed sampling.
As shown in Figure 8, when the completed parameter F LUG of expression sampling is " 1 " (S40: be), CPU24 carries out FFT computing (S42) and parameter F LUG is turned back to " 0 " (S44).Calculate each spectrum intensity (amplitude) (S46) according to the FFT operation result.CPU24 extracts the spectrum intensity peak value (S48) of approaching horizontal frequency from result of calculation, and tries to achieve tension force by the spectrum intensity that is extracted.The output signal of each Sensor section S1-S6 just equals tension force.The tension force that is obtained is stored among the memory device 24f.Sampling (Fig. 7) and tension force calculate (Fig. 8) to carry out simultaneously.
By utilizing the yarn tension that is obtained, for example, the rotating speed of may command spindle 7 maybe can be monitored unusual yarn tension.Because for each rolling P1-P6 detects yarn tension, therefore, can control according to the aviation value or the predetermined tension force that rolls of aviation value, two ends (P1, P6) or middle (P2, P5) tension force of 6 tension force.
