【摘要】：高精細(xì)金屬絲網(wǎng)主要應(yīng)用于高精度過濾、電路印刷和智能應(yīng)用,特細(xì)金屬絲整經(jīng)機應(yīng)用于高精細(xì)金屬絲網(wǎng)織造的整經(jīng)環(huán)節(jié)。課題源于杭州恒益篩網(wǎng)有限公司委托開發(fā)特細(xì)金屬絲整經(jīng)機,從而進行高精細(xì)金屬絲網(wǎng)開發(fā)。整經(jīng)是將一定根數(shù)的經(jīng)紗按規(guī)定的長度和寬度平行卷繞在經(jīng)軸上,且保持一定張力的工藝過程,是重要的織前工藝。該公司原有金屬絲整經(jīng)設(shè)備無單絲張力控制,且筒子架容量小;無片紗張力精確控制機構(gòu),橫移量無法精確控制,只能滿足直徑0.025mm及以上的金屬絲整經(jīng)。為了開發(fā)高精細(xì)金屬絲網(wǎng),尤其是直徑0.02mm及以下機織金屬絲網(wǎng),需要開發(fā)特細(xì)金屬絲整經(jīng)機。本文在研究特細(xì)金屬絲整經(jīng)特點、整經(jīng)工藝以及當(dāng)前金屬絲整經(jīng)機不足的基礎(chǔ)上,主要研究了特細(xì)金屬絲整經(jīng)中的單絲張力控制方式及筒子架結(jié)構(gòu),片紗張力控制算法及特細(xì)金屬絲整經(jīng)機研制。(1)單絲張力控制與筒子架結(jié)構(gòu):通過進行重錘摩擦盤式、重錘張力桿式及無單絲張力調(diào)節(jié)的單絲退繞對比試驗,結(jié)果表明重錘摩擦盤式單絲張力控制方式比其他機械控制方式的單絲張力更加穩(wěn)定,且可通過調(diào)節(jié)保證筒子架上任意位置上的紗管單絲退繞張力一致;針對筒子架容量大、對金屬絲摩擦小的要求,采用了 V型錯位對稱結(jié)構(gòu)的筒子架,減小金屬絲在被聚攏前受到的摩擦力及轉(zhuǎn)角,提高了容量;設(shè)計中使用電磁制動器對紗管隨動軸制動,電磁制動器的響應(yīng)時間為0.3s,實現(xiàn)了斷線或停車時及時制動,避免紗管慣性退繞。(2)片紗張力控制算法:通過研究張力形成原理,在片紗張力控制系統(tǒng)中采用雙閉環(huán)的控制,實現(xiàn)了恒線速度收卷和恒張力收卷。采用基于卡爾曼濾波的PID算法閉環(huán)控制收卷線速度。由于收卷過程中卷徑不斷變化,必須對收卷伺服電機變速控制。由編碼器檢測實時線速度,使用卡爾曼濾波器濾波,經(jīng)過PID算法控制輸出量大小,從而動態(tài)調(diào)整收卷伺服電機轉(zhuǎn)速,此算法實現(xiàn)了恒線速度收卷。采用積分分離式PID算法閉環(huán)控制收卷張力。收卷張力控制響應(yīng)必須具備準(zhǔn)確性、穩(wěn)定性,此外必須保證無超調(diào)量,避免對金屬絲造成物理損傷。采用積分分離式PID算法,既保證了系統(tǒng)的靈敏度、準(zhǔn)確度和穩(wěn)定性,又使得系統(tǒng)輸出無超調(diào)量,從而達到了恒張力無超調(diào)收卷目的。(3)結(jié)構(gòu)設(shè)計及電氣控制系統(tǒng)設(shè)計:設(shè)計制造了 500支紗管容量的筒子架和整經(jīng)臺。其中整經(jīng)臺包含聚攏機構(gòu),片紗張力控制機構(gòu),收卷機構(gòu),橫移控制機構(gòu)及分絞機構(gòu)。通過筒子架和整經(jīng)臺的配合,實現(xiàn)了特細(xì)金屬絲恒張力收卷,且單絲張力均勻,片紗張力恒定。
[Abstract]:High precision metal wire mesh is mainly used in high precision filtration, printed circuit and intelligent application, the super fine metal wire warping machine used in high precision metal wire mesh weaving warping process. Subject comes from Hangzhou Hengyi filter limited company commissioned the development of super fine metal wire warping machine, thus the high fine metal mesh whole development. Is a certain number of warp yarns according to the provisions of the length and width of parallel winding placed on the process, and maintain a certain tension, is an important process before weaving. The company's original wire warping equipment without filament tension control, and the creel capacity is small; no yarn tension control mechanism, shifting the amount cannot be controlled accurately, can only meet the diameter of 0.025mm and above the metal wire warping. In order to develop the high fine metal mesh, especially the diameter of 0.02mm and below the woven wire mesh, the need to develop super fine metal wire warping machine. The Wen Zaiyan The super fine metal wire warping characteristics, warping process and the wire warping machine on the basis of the shortage, mainly studies the filament tension control methods and structural characteristics of thin metal wire creels warping of the yarn tension control algorithm and super fine metal wire warping machine is developed. (1) monofilament tension control and creel structure by friction disc hammer, hammer rod and filament tension unwinding contrast test monofilament tension adjustment, results show that the friction disc weight monofilament tension control mode is more stable than single wire tension control methods of other machinery, and by adjusting the guarantee on the bobbin rack the bobbin unwinding tension wire in view of the creel; large capacity, small friction requirements on the wire, the creel V type dislocation symmetrical structure, reduce the wire in friction angle and gather all the pre, improve the design capacity; In the use of electromagnetic brake of bobbin servo shaft brake, electromagnetic brake response time is 0.3s, the disconnection or parking brake timely, avoid inertia. (2) unwinding bobbin yarn sheet tension control algorithm: through the study of the forming principle of tension, the double closed-loop control of the yarn tension control system, realizes the constant speed winding and constant tension winding by using PID algorithm. The closed-loop Calman filter control rewinding speed based on the line. Because the coil diameter changing winding process, must be on the winding servo motor speed control. By the encoder to measure the real-time line speed, using the filter Calman filter, through the PID algorithm to control the quantity of output thus, the dynamic adjustment of the rolling speed of servo motor, this algorithm realizes the constant line speed coiling. The rewinding tension is controlled by the integral separation PID algorithm. The closed-loop tension control response must have accuracy and stability In addition, qualitative, must ensure that no overshoot, avoid to cause physical damage to the wire. The integral separation PID algorithm, which ensures the system's sensitivity, accuracy and stability, but also makes the system output without overshoot, so as to achieve the constant tension winding without overshoot. (3) the structure design and the electrical control system design: 500 bobbin creel capacity and warping. The design and manufacture of the whole table contains the gather mechanism, a yarn tension control mechanism, a rolling mechanism, sliding control mechanism and dividing mechanism. Through the warping creel and Taiwan cooperation, realize super fine metal wire tension coiling, and monofilament uniform tension, yarn tension constant.
