Description
Technical field
The utility model belongs to industrial automatic control device technique field, be specifically related to the micro-tension sensor that a kind of automatic winder is used, be specially adapted to the yarn detection of suffered tension force at the volley, in addition applicable to stressed detection and the sensing at the volley of the object to electric wire, optical fiber cable, tape, steel band or plastic sheeting and so on.
Background technology
With regard to textile industry, in the textile technology process, the variation meeting of yarn tension directly affects yarn qualities and even affects the quality of fabric, because world clothing, yarn in advance.Therefore in middle nineteen nineties, in the textile machine take automatic winder as representative, particularly the automatic winder of international advanced type and doubling frame etc. all are equipped with tension pick-up, realize the closed-loop control of yarn tension.Because the number of sensors that production equipment need be used is numerous, be subjected to the restriction of device fabrication cost, often be difficult to adopt the tension pick-up of expensive Instrument Level, therefore the production line level sensor accuracy that adopts is low, restricted equipment tension force and controlled the raising of index, and even the application of the automatic winder of production line level and doubling winder upper sensor is also very few in China.
The production line level micro-tension sensor of being produced by France is a kind of simulating signal Minimal Tension sensing device that changes based on the metal electric resistive, this sensor price is low, application quantity is large, but because technical indicator is low, consistance is poor, substitute owing to there is no at present the good sensor of technical indicator again, so textile machine production firm has to accept sensors with auxiliary electrode were.The micro-tension sensor of the simulating signal based on the ceramic substrate resistance strain plate of being produced by Switzerland is for the domestic simulating signal micro-tension sensor of aforesaid method, the strong point that precision is high and consistance is slightly good is arranged, but price is very expensive, be difficult to be generalized on automatic winder or doubling frame, use seldom so far.
The tension pick-up of above mentioned ceremony device level and method are domestic all adopts the resistance strain plate technology with tension pick-up Swiss, discrete type due to the element material performance, easily cause the absolute precision consistance poor, and due to the restriction that is subjected to ultimate principle, serviceable life is relatively short, and lasting stability, reliability and environmental adaptability are unsatisfactory.In addition, also due to produce and the testing and measuring technology requirement comparatively harsh, manufacturing cost is high.Therefore a kind of precision high price is low is fit to the micro-tension sensor that the textile industry production line uses, and is the important topic of research and probe in the industry.
Chinese invention patent application publication number CN101314878A has recommended a kind of high speed, fine-tension force rove testing apparatus, be applied to become rove in sliver process multistage stretching process, and the detection that keeps permanent tension force in the high speed twisting process, realize zero-bit adjustment to sensor by magnetic induction coil at broken yarn not during in the situation that stop, use and guarantee the online precision that detects of Minimal Tension rove.This patented claim scheme is based on publication number CN101382465A(dynamic tension sensor) and notification number CN201301377Y(micro-tension wire breakage sensor) the undocumented structure that is positioned at the conducting parts at place, test side proposes in these two patent schemes, that is to say that CN101314878A has done improvement to the conducting parts of test side, specifically can be referring to Instructions Page 2 the 1st to the 3rd row of this patented claim; Principle of work is capable referring to Instructions Page 3 6-13.This scheme belongs to the magnetic induction category, though strong point simple in structure is arranged, the accuracy, consistance and the stability that detect can't show gratifying degree.
Invention patent mandate notification number CN100356152C has disclosed a kind of power sensor of automatic detection device, this patent is the formal output that tension variation with testee changes with voltage linear after with changes of magnetic field more equally, therefore with the shortcoming of depositing last patented claim scheme.
" intelligent micro-tension sensor " (this patent is proposed by the applicant) that invention patent mandate notification number CN101806647B introduces, this patent scheme objectively can be cashed the technique effect that refers in the technique effect hurdle of its instructions, specifically can be referring to 0009 section and 0019 section, the instructions of this patent.but still there is following shortcoming in this patent scheme: one, due to Yarn guide mechanism by upper, lower guide sheet and stressed guide sheet form, wherein: on, lower guide sheet is fixed on housing, and stressed guide sheet is fixed in an end of displacement transmission levers, and substantially corresponding to upper, between lower guide sheet, more precisely, on, lower guide sheet and stressed guide sheet three form the position relationship of isosceles triangle each other, the other end at the displacement transmission levers arranges eddy current generation sheet, the eddy current coil that this eddy current produces on signal numerical value control and treatment circuit plate (being accustomed to the title control circuit board) in sheet and the shell chamber that is arranged on housing is corresponding, therefore drawing from the unwinding pipe at yarn and being wound into the process of a yarn by take-up bobbin, yarn needs the 3rd yarn guiding face on lower guide sheet successively, the second yarn guiding face on stressed guide sheet and the first yarn guiding face on upper guide sheet, the tension variation of yarn passes to stressed guide sheet, so when stressed guide sheet produces the displacement consistent with the yarn tension size, just drive the displacement transmission levers by stressed guide sheet, make aforesaid eddy current produce also corresponding displacement of sheet, thereby by eddy current coil, signal feedback is processed (specifically can referring to 0032 section, instructions) to signal numerical value control and treatment circuit plate.Hence one can see that, and signal numerical value control and treatment circuit plate need to rely on the winding tension changing condition that just can measure yarn in the variation of the big displacement quantity of the displacement transmission levers that is provided with eddy current generation sheet, thereby accuracy of detection is difficult to guarantee; They are two years old, as aforementioned because Yarn guide mechanism consists of upper and lower guide sheet and stressed guide sheet, so rigging error of upper and lower guide sheet and housing, and the site error of the site error between upper and lower guide sheet and stressed guide sheet and even eddy current generation sheet and eddy current coil objectively exists, only the degree difference difference, so this error can affect the accurate effect that signal numerical value control and treatment circuit plate detects the yarn winding tension equally; Its three, due to complicated integral structure, for example the upper and lower guide sheet of Yarn guide mechanism and stressed guide sheet form, and and for example also need use the displacement transmission levers except using signal numerical value control and treatment circuit plate, therefore, cost of manufacture is large, price is high; Its four, because overall volume is large, thereby be not easy to install.
In view of above-mentioned prior art, be necessary to be improved, for this reason, the applicant has done useful design, has finally formed technical scheme described below.
