The present invention is directed to the form of air ring to carry out redesigning its relevant mechanism, make ring rail position fix, and the position of spindle can control。Such air ring is converted into stable state by dynamically change。So the kinestate for unpowered element wire loop is just converted into plane motion by space screw motion so that balloon tension is more stable to the control of wire loop, it is possible to reduce the burst tension force of air ring, it is also possible to extend the life-span of wire loop。By the demonstration to air ring equation so that it is be well grounded in theory, thus mechanism is carried out targeted design, the Control System Design broken traditions。This is keeping the conventional roll improvement around the basis of twisting mechanism not by type, but for a kind of new design of drafting mechanism of spinning machine, drive mechanism and Automated condtrol mechanism。Ingot position formula list spindle spinning frame reel system can be controlled and replace traditional cam shaping mechanism mainly by motor or other servomotor, and according to its characteristics of motion, the process of winding is controlled。

In spinning frame of the present invention, the first motor 1-2 is placed on base 5 top, from the scattered yarn that drafter device 2 is sent, being wound onto through guide button 1-4 inserts on the spool of spindle blade 1-1-1, spindle blade 1-1-1 is linked on a High-speed DC motor 1-1-5 by high-speed bearing 1-1-3 by flexible connector 1-1-6, this High-speed DC motor 1-1-5 is arranged on inside a spindle case 1-1-7, this spindle case 1-1-7 is arranged on spindle case fixed mount 1-6, a spindle blade fixed block 1-1-4 is had to be enclosed within spindle 1-1-2 between high-speed bearing 1-1-3 and High-speed DC motor 1-1-5, spindle traverse one ring rail 1-5, whole spindle system device is installed on a fixed slip bar 6, first motor 1-2 drives synchronous toothed belt 1-3 transmission, synchronous toothed belt 1-3 drives whole above-mentioned spindle system device to realize the elevating movement of spindle system, in this drafting system of spinning frame device part, front roller 2-2 is driven by the second motor 2-5, rear roller 2-4 is driven by the 3rd motor 2-7, it is driven by change gear 2-6 by middle roller 2-3 by rear roller 2-4, second integrated velocity sensor 2-8 realizes roller rotating speed is monitored, the speed of the 3rd motor 2-7 is controlled according to the process controlled automatically by electric control system, the speed of the second integrated velocity sensor 2-8 sends into electric control system, and be analyzed judging to leading second multiple by electric control system, thus realizing on-line checking and control, drafting system device is integrally attached on reel cage 2-1, for realizing the state of the first motor 1-2 and High-speed DC motor 1-1-5 is controlled, a photoelectric speed sensor 1-7 is installed additional respectively at the first motor 1-2 direction of principal axis, the alignment probe of photoelectric speed sensor 1-7 is fixed on the scale 7 on lathe, the back side of this scale 7 is to be close to a magnetic sheet 8, the cross section of the gear 1-1-8 of the drive of direct current generator 1-1-5 installs additional the first integrated velocity sensor 1-1-9。

In reel system device, around us in order to realize spindle 1-1-2 dynamic volume traditional reel system is improved and designs, it is proposed that a kind of new winding mechanism。The up and down motion of spindle 1-1-2 is driven synchronous toothed belt 1-3 by the first motor 1-2, drives the entirety of spindle 1-1-2 to move up and down, and wire loop is fixed on ring rail 1-5。Ring rail 1-5 is then fixed in frame, remains stationary as and maybe can finely tune。Spindle 1-1-2 completes not constant speed raising and lowering along with the up and down motion of synchronous toothed belt 1-3, and the level that simultaneously can realize spindle 1-1-2 easily rises。The function of the reel system of conventional spinning frame can be replaced completely。In order to realize cone cross winding, the size such as the equation of motion of spindle 1-1-2 lifting and the speed of conventional spinning frame ring rail 1-5 and acceleration is identical, but in opposite direction。

Utilizing ring rail 1-5, the control of front and back roller and ingot speed can obtain the mathematical model of motor-driven so that spindle 1-1-2 has an excellent molding。By theory analysis can obtain this system volume around time, yarn burst tension force is only small, therefore can pre-for tension force value be obtained relatively big, and then realizes higher ingot speed winding, so namely traditional cam mechanism, ratchet mechanism, the mechanical part that winding gear and twist transformation gear etc. are complicated can be saved。Improve the reliability and maintainability of the running precision of mechanism, machine, reduce the labor intensity of workman。

First motor 1-2 can drive synchronous toothed belt 1-3 to drive spindle 1-1-2 to lift with certain speed, and ring rail 1-5 keeps fixing, the motor speed of photo-electric pulse codr and front roller, rear roller and location stepping is used to keep synchronizing with the rotating speed of spindle 1-1-2。This reel system just can realize synchronous coordination work, it is achieved balloon shape constant type winds。For realizing the high-speed winding of spindle 1-1-2, adopt single ingot transmission, so can provide more free and be accurately controlled, reduce difference between ingot, improve the quality of production and efficiency。

Driving for spindle can be mainly made up of the resistance three parts of the winding tension of frictional force and yarn and air, there is practical situation analysis can take by force the frictional force controlling resistance and spindle self, being winding tension for determining the large and small ultimate strength that can take its yarn of yarn tension, this is also the extreme value that Yarn break is likely to get。For this present invention with maximum (top) speed 25000r/min, the radius of rings is 48 millimeters, and the ultimate strength of yarn is 400g is reference design, it is possible to the power being calculated High-speed DC motor 8 by horse-power formula is 241.18 watts。ZyKw55-1 type direct current generator can be selected。Spindle 5 is driven by High-speed DC motor 8, torque less (< 0.00047N m) needed for actual rotation, in the present invention, adopts the High-speed DC motor of Chang'an, packet header magneto research and development You Yan company。

This spinning frame can cancel shaping cam and the mechanism such as ratchet, chain of transmission so that design more compact rationally。Can by the various parameters of above-mentioned motion for realizing that the modern times automatically control。The step number of the first motor 1-2, execution time etc. put in the memorizer of electric control system, this can replace source data easily, also incorrect data can be processed, electric control system control rotation and the lifting motor of spindle 1-1-2, direct current generator 1-1-5 so as to coordinate。

The spinning frame twist controls and in the engagement process of winding, for ensureing spun yarn brute force and quality in spinning frame winding process, controls to become equally important to its twist。In the present invention, the twist of spun yarn can be driven front roller 2-2 by the second motor 2-5, the 3rd motor 2-7 drive rear roller 2-4, coordinates transition gear to realize drawing-off to rove, and match with the rotating speed of spindle 1-1-2 and can realize the control to the twist。The size of the twist depends on the speed of spindle 1-1-2 and the difference of the rotational frequency of wire loop, owing to wire loop is the element that a non-powered directly drives, is therefore difficult to change the rotating speed of wire loop in practice。By changing the speed of front roller 2-2, change the length of winding yarn and then change twist value, so with the rotating speed of the speed of roller and spindle 1-1-2 carries out。Just can be met the yarn that we require。

In the present invention control process to spindle 1-1-2 speed, directly driving spindle 1-1-2, such simple in construction with direct current high-speed electric expreess locomotive 1-1-5, drive circuit industrialization easily realizes with electric control system mouth simultaneously。When the excitation voltage of direct current generator and load torque are equal, armature voltage is big, and motor speed is high, and voltage drop is as low as zero right, motor stalls。

In application to sensor and motor, to sensor and the second motor 2-5 designed, we utilize sensing to clamor and can realize the monitoring to system, simultaneously by performing the realization that device completes to control。Mair motor selects high-speed electric expreess locomotive, electric control system carry out speed governing, and interface simply can realize ingot speed real-time speed is controlled。Motor selected by other motor, it is possible to completing many motors ground synchronous variable-speed, simultaneously step motor control is flexible, and not easily step-out, and control accuracy is high。It can matching coding device driver corresponding with motor work together, constitutes a closed loop control, and asks when having less response, it is possible to meets the needs controlled。For controlling to doff, begin to spin the position of position and full packages, we have employed proximity switch, integrated speed probe and highly sensitive position sensor。The present invention selects Hall element, and this is a kind of sensor that make use of your effect measurement of shake。It is possible not only to carry out non-cpntact measurement, can obtain energy not against magnetic field again。
