The utility model is characterized in that the rotary disc type barrel-changing device (3) is connected with a servo motor (5) which is controlled by a single-chip microcomputer by the chain driving mode. The rotary disc type barrel-changing device of the utility model can be continuously and unremittingly operated with the change of the diameters of spooling during a spooling period, the position of the touch roll is always remained constantly and unchangeably during the spooling period, the utility model is more favorable to keep constant spool surface tension in a winding barrel, and the utility model can effectively avoid the factors of unstable spool formation, etc. which are caused by the impact to the spool surfaces caused by the intermittent motion of the touch roll and the subtle change of surface contact pressure; therefore, the formation effect of a spooling barrel can be better.
Description
(1) technical field
The utility model relates to a kind of textile machine, particularly the rotating disk continuous rotary winding mechanism of doff moulding in the chemical-fibres filaments take-up winding facility.
(2) background technology
Chinese patent 89109429.6 discloses the winding mechanism that is used for the doff moulding in a kind of chemical-fibres filaments take-up winding facility.It is to be made of a rotation disc type creeling device that two winder axles are housed and a yarn transversing mechanism and a touch roll, this transversing mechanism and touch roll are arranged on before the disc type creeling device in the yarn path, the circumference of the package that is forming on touch roll and the winder axle (work winder axle) contacts, and owing to the disc type creeling device a doff in the cycle also the increase along with roll diameter change, wherein touch roll is installed on the support, the move mode of this support can make touch roll finish a stroke action that has the radial component of relative work winder axle, and predetermined application force acts on the touch roll with the sense of motion of support; Creeling device links to each other with a rotation transmission device, this rotation transmission device can drive creeling device, the distance between shafts of touch roll and work winder axle is increased, this rotation transmission device comprises a control system that has sensor and control device for pivoting, the stroke action of sensor touch roll, rotation transmission device can be controlled by this sensor that reacts the side-play amount of the desired location of touch roll and actual position in this control system, and the position of touch roll is remained unchanged substantially at a doff periodic process.
As can be seen from the above description, the key point of this mechanism is: at a doff in the cycle, the distance between shafts of this touch roll and work winder axle is constantly to change along with the variation of roll diameter, and its position also be along with the variation of roll diameter constantly batch (-type) ground change, the scope of its variation (side-play amount) is subjected to the control of sensor; If problem just is in the batch (-type) ground variation constantly along with the variation of roll diameter of the position of doff touch roll in the cycle, doff tube surface will be subjected to the small impact of a wavy variation of sawtooth incessantly so, thereby bring the wavy subtle change of sawtooth of doff surface contact pressure, the instability that causes doff to be shaped.
(3) summary of the invention
The purpose of this utility model provide at existing weak point in the above-mentioned prior art just a kind of disc type creeling device can a doff in the cycle with the doff diameter variation the continuous rotating disk continuous rotary winding mechanism of uninterrupted action.
The purpose of this utility model can realize by following measure:
Rotating disk continuous rotary winding mechanism of the present utility model comprises the rotating disc type creeling device, is installed in two winder axles on the rotating disc type creeling device and presses therein touch roll on the work winder axle by link span by driver train; Described rotating disc type creeling device by the chain-drive mode be connected by monolithic processor controlled servomotor.
Principle of work of the present utility model is as follows:
During rotating disk continuous rotary winding mechanism normal winding of the present utility model, yarn is wound on the work winder axle by touch roll, increase along with winding diameter, distance between shafts between touch roll and the work winder axle increases gradually, promptly is its initial position and position just in working order as position I among Fig. 2 and position II.We know, a doff in the cycle winding speed of yarn be invariable, thereby the cireular frequency of touch roll also is invariable in the cycle at a doff, again because touch roll all is passive rotation in the cycle at a doff, so forming the linear velocity V at the surperficial maximum gauge place of yarn tube in its linear resonance surface velocity V and the work winder axle equates, again according to work winder each instantaneous actual speed n of axle (the sensor rotating speed of closed loop control), can go out the doff diameter (D=V/ π n) of this instantaneous work winder axle at once by the Computing system-computed, and the recruitment Δ D of doff diameter, thus, intrinsic size according to mechanism itself, just can calculate easily this instantaneous disc type conv the angle [alpha] that should rotate, because this revolution is that extremely trace also requires very accurate, therefore, the utility model adopts servo (motor) control system to finish the angular displacement alpha of disc type creeling device, and this system can very accurately realize the instantaneous angular transposition requirement arbitrarily of disc type conv.Like this at each doff in the cycle, increase along with winding diameter, the disc type conv is promptly according to the result of calculation of Computing system, under servomotor and chain drive, keep continuous fine motion, thereby guaranteed each doff in the cycle touch roll instantaneously both acted on doff tube surface at each with certain pressure, keep its position invariable again, thereby also just guaranteed the stability of doff tube doff, guaranteed the quality that doff is shaped.When a doff cycle finished, the Computing system promptly notified the servomotor fast rotation, and another doff axle is switched to control position, and the doff that enters next cycle is reeled.
The utility model has following outstanding feature compared to existing technology:
See on the characteristics of motion that 1, the disc type creeling device in the utility model is at a doff in the cycle
Can uninterruptedly move continuously with the doff diameter variation; And the disc type of prior art is changed
The tube device is controlled between formation by sensor and driving device in the cycle at a doff
The formula of having a rest mode of motion;
2, from motion result, the position of touch roll is a doff cycle in the utility model
In remain invariable; And in the prior art position of touch roll at a doff
Batch (-type) changes with the variation of winding diameter in cycle;
3, on the effect of winder moulding, the touch roll position is protected in the cycle all the time at a doff
Hold constant but not intermittent movement, more help keeping in the winder yarn tube capillary
Constant, can effectively avoid the impact that brings because of the touch roll intermittent moment to yarn tube surface
The factors such as yarn tube moulding instability that cause with the subtle change of surperficial contact pressure, from
And make that the forming effect of doff tube is better.
