[summary] traditional fly frame, use cone pulley more (common calls iron prepare Chinese medicine by roasting it in a panbig gun) with difference fast box device, on rigid structure more complex, rely on change the adjustment of the means such as gear spinning parameter means, incommensurate already client is friendly to high speed, tall qualitative, big package, man-machine model fly frame demand; At the same time the poor dissimilation of contemporary spin technology and craft develops, in requirement spinning process can fast effective adjustment controls Zhu Yuan. The independent four-axle that at present my company develops hangs ingot fly frame, get used to this one requirement very well. [keyword] HMI of transducer of servo of fly frame PLC one, foreword fly frame is drawing hind ripe a roving that machines different name number and number of turn, spin the equipment that makes spun yarn for spun yarn machine, applicable general combs and the combing cotton fiber, chemical fiber under 60mm reachs other blending fiber. The technology of our country fly frame progresses, develop to the other equipment of traditional spinning in the photograph in going a few years relatively lag. This has much talk fly frame to change one-way fly frame among them, the effect that suffers progress of spun yarn technology and the interference that exceed machine of big draft spun yarn to develop development to argue. 20 centuries 90 years since, the maturity as structure of advanced fly frame machinery and control theory, the high speed that gets used to client demand, tall qualitative, big package, man-machine is friendly model fly frame gets rapid development. Fly frame falls of gauze process different, cent holds ingot in the palm type and the type that hang ingot; Hang amount of axis of electric machinery of basis of ingot type fly frame to divide again among them: Type of two axes type, triple axle, four-axle and fly frame of 7 axes type; Four-axle hangs the stress that ingot type fly frame develops for epicycle technology. Four-axle hangs ingot type fly frame to be divided again the belt is poor fast box type and four-axle independence type; The article is based on a stage to amount to mechanical and electrical products, with respect to the four-axle that frequency conversion and servo form independent type hangs ingot fly frame to elaborate its technology point. 2, rigid structure and relevant craft 1.

Gimbal 　 　 pursues the requirements of 3 principle of Luo La draft according to spinning craft, fly frame sliver ripe a classics after Luo La draft, by before Luo La gives gauze, ingot ala constant speed rotates undertake twisting; At the same time winding system drives bobbin to rotate, according to the requirement that package shapes, get on the gauze winding after twisting in bobbin. As a result of before it is constant that Luo La gives gauze rate, winding rate falls as the accretion of winding diameter fast. Dragon muscle is slow at the same time litre fall, hold in the palm move the gauze on its to provide action of fluctuation move back and forth, cooperate winding device to make yarn chases a layer to twine go up in gauze canal, until arrive to set number of plies or yarn length beforehand. In fact, the complete fly frame that hang ingot still should include clean unit: The fly frame that hang ingot uses cleanness of fluctuation of active circumgyrate type generally implement. As a result of its the structure becomes independent, working way is relatively simple, the article no longer give uncecessary details. 3, the electrical system structural frame that is based on a stage to amount to mechanical and electrical products 1.

The structural frame of electrical system thinks four-axle hangs ingot type fly frame independently, the key that controls a system depends on the synchronous scale linkage of four-axle, come two axes fly frame differs imitate the process that fast box synthesizes each axis speed; Four-axle hangs course of start of system of ingot type fly frame independently in, each axis speed asks to have tall response gender and stability. In the meantime, electric machinery asks to have capacity of fast and effective meet an emergency to the reasonable change of exterior load. The above technology feature that is based on equipment and client are high quality requirement, combinative stage amounts to complete, overall product line, we choose a stage to amount to EH2 series PLC to regard as advocate accuse, choose a series that amount to VE axis of ala of ingot of control of high-powered vector transducer; The stage amounts to servo of A+ series high-power to control winding axis; Luo La axis and dragon muscle axis choose a servo of the series that amount to AB to control respectively; Feeling screen amounts to interface of A series true colour for the stage. 2.

If the electrical system that the integral compose framework of electrical system builds pursues 4; Graph structural frame of 4 electrical system 3.

Basically control A of 　 of function of parts of an apparatus. Touch screen: Four-axle hangs set of parameter of ingot type fly frame the amount is large, this screen but intuitionistic, convenient set and monitoring all sorts of parameter; B. PLC: EH2 series, operation rate is rapid, support output of pulse of 4 high speed, stable and reliable, can expand according to control technology I/O check the number; C. Luo La servo: Provide power of Luo La axis, rate is constant, size is mixed on ingot ala rotate speed definitely number of turn; D. Winding servo: Offer gauze to provide winding power, rate increases along with the winding diameter of gauze and reduce; E. Dragon muscle servo: Offer dragon muscle to rise fall motivation, litre fall rate is minorrer, yarn is twined closer; F. Ingot ala frequency conversion: Provide power of ingot ala roll coming back, rate is constant, by feeling screen set; Frequency conversion system adds outfit speed to return the check that award PG, electric machinery adds outfit stage to amount to coder, realize closed-loop control. The configuration that accuses box considering fly frame report is further from nose, environment of applied spot electromagnetism is complex, the proposal chooses differential coder. 4.

Periphery controls circuit to ask according to craft, the paralell connection on fly frame body installs much group to handle a case, set on box of every groups of operations start, stop, the dot uses button, all can open stop a dot to use whole platform machine, with operation of convenient files lathe work; In spinning process, break gauze all ask to jockey automatically, reason adds outfit photoelectricity sensor, already detected gauze it is normal to whether work; Spinning shapes finish, dragon muscle drops automatically to fall gauze position, convenient spinner gets off quickly spindle; In the meantime, spindle gets off finish after spinning roving, install new gauze tube again, operation feeling screen is relevant pushbutton, requirement dragon muscle rises automatically the position is circled to stop first, will new handiwork twines the yarn that crosses ingot ala to be in charge of in gauze the position is circled first, the operation starts pushbutton, new spinning procedure begins. This is about to beg, in the journey that gets on next rising to fall in dragon muscle, add outfit fall gauze position detects switch, the position is circled to detect first switch. Get on next rising to fall considering dragon muscle the journey cannot exceed limiting value, must add limit of fluctuation of the muscle that install dragon to detect switch. Above reference point, receive PLC to input a dot directly, control is handled by PLC operation logically; ° pursues the parameter set interface of program of 5 feeling screen 4, debug difficulty, point to reach answer 1.

Yarn tension controls four-axle to hang ingot type fly frame, pull extended yarn from Luo La, need to cross ingot ala to form number of turn to be twined again go up in bobbin, whole process is a dynamic process; Because number of turn is finite, the ultimate tension of yarn is lesser, in whole spinning process, the wave motion that accepts sex of synchronism of linkage of transmission machinery scale, gauze is in charge of the error that diametical theory is worth and is worth actually constantly, the fluctuation that causes yarn to give gauze seat is fluctuant (if pursue,3 arrowhead location is shown) , big wave motion affects spindle to shape not only quality, exceed broken end even, make overall stop machine, affect spinning efficiency. Kind of way basically divides to solve afore-mentioned problems inside the industry at present: The first kind: By tensional CCD sensor online detect roving tension, feedback arrives PLC operation. This kind of means, bring down core operation difficulty, simplified to twine the control computation quantity with dragon muscle axis. But in because CCD detects,using a process actually, taller to environmental requirement, must maintain lens face cleanness, and face market cost pressure, this kind solves means to gain ground degree not tall, but be worth to pay close attention to. The 2nd kind: In standard theory computational formula falls, increase tension to amend an order, then rotate speed of canal of fine tuning gauze coming back is spent and dragon muscle rises fall speed, achieve the goal that adjusts roving tension. Ask to call different compensation coefficient automatically in the light of different yarn at the same time. What its use generally is speed of axis of winding of compensation fine tuning. This kind of means, cost is small, the effect is apparent, lai Yu notting comply detects exterior parts of an apparatus, flexible good. But when debugging, should check repeatedly, accumulate different yarn to tie numerical value in the correction of different number of plies ceaselessly. This case uses this means. 2.

Of dragon muscle position cut off the power memory is when spinning, spindle is twined half-baked when the system is outside cutting off the power often exist, after new electrify, the position before requirement roving function continues to cut off the power and parameter continue spinning. As a result of the market mostly servo driver is increment type coder, cut off the power cannot remember an axis current position; This case joins through 4N25 light PLC and servo driver coder output a mouth occasionally, cut off the power through PLC memorial division will remember value of the position before cutting off the power. If its join means pursues after coder of servo of 6 dragon muscle is changed through 4N25, 6 　 graph receives PLC3.

Overall open the control that stop to be in in fly frame spinning initiative phase and when will be being finished, lesser or spindle radius correspondence is bigger, if set top speed with screen,run right now, yarn leaves mental efforts and spinning middle difference bigger in what twine the brim, go against form high quality spindle. This asks initiative phase mixes spinning when will be being finished overall speed is reduced move, reduce broken end rate, improve gauze quality. The automatic rate that each spinning phase must design in the program changes a course. Graph 7 spinning shape middle 5, conclusion is the four-axle that relies on research and development to hang ingot type fly frame to already was in Shandong independently with afore-mentioned plan research and development of some spin machinery plant is successful, ingot ala rate is top can amount to 1350r/min, spindle shapes well-balanced, consistency of yarn platoon cloth is good, shape yarn length can amount to 3200m; Number of turn, spindle shapes angle, shape length, spinning length all but flexible set. Spinning pulling force is more steady, in ingot fast the broken end below 1100r/min condition is in 0.

5 / less than of stage · hour. Have fall automatically gauze and search automatically positional function is circled first, reduce spinner labor intensity effectively, improved labor efficiency, market prospect is capacious. The stage is amounted to have the whole industry such as interface of transducer, PLC, servo, man-machine, coder to dominate product line of parts of an apparatus, offer advanced and comprehensive solution for the client. Be aimed at fly frame industry, dakedi offers the desk frequency conversion of type of two axes type, triple axle, four-axle or servo whole solution, can satisfy client individuation requirement at the same time. Be based on the ceaseless progress of spin industry technology, the spin industry application that the company establishs technically is in, serve spin industry. CNC Milling CNC Machining
