Description

Spinning take-up machine
The present invention relates to spindle driving type (ス ピ Application De Le De ラ イ Block イ プ) spinning take-up machine, it is with the revolution of the peripheral speed application cylinder base of touch roll, and above-mentioned touch roll is to make the seat of reel revolution, contact and along with rotating with bobbin on being contained in seat of reel.
Spinning take-up machine is that the spun spinning winding of spinning machine is upward formed package to the pipe that batches that is contained on the seat of reel.This spinning take-up machine has friction driving type (Off リ Network シ ョ Application De ラ イ Block イ プ) and spindle driving type, the former drives the friction roller revolution that contacts rotationally with bobbin (comprising the general name of batching pipe and package), and the latter drives the seat of reel revolution.In the spindle driving type spinning take-up machine and since spinning from spinning machine by certain speed spin, therewith relatively the package forming process its diameter become gradually greatly, thereby must control the revolution of seat of reel explicitly therewith, it is reduced gradually.
For the revolution of application cylinder base, usually use the touch roll relative with seat of reel, it is to contact with bobbin and along with turning round, applying the contact pressure of regulation and detect peripheral speed.Obtain the peripheral speed of package by the revolution that detects touch roll, with itself and setting speed comparison and the revolution of application cylinder base makes the coiling speed of package certain.But, in this spindle driving type spinning take-up machine, along with understanding on the rotating touch roll slippage takes place owing to contact with bobbin, thereby must estimate the revolution control of carrying out seat of reel under the situation of this slippage, and slippage is bigger when high-speed wind-up, and also change easily of slippage itself.Because be that peripheral speed with touch roll is the running of benchmark when slippage takes place, thereby the peripheral speed that actual detected arrives is slower, spinning is to batch with being stretched, can cause coiling tension to improve, and causes projection package shape defects such as (バ Le ジ).
So drive touch roll auxiliaryly with CD-ROM drive motor.Generally, as the CD-ROM drive motor of touch roll, it is to change output frequency with changer with induction motor, uses with the proportional revolution of this output frequency and turns round driving.
Contact and along with windage loss mistake, mechanical loss being arranged and on the rotating touch roll with the bobbin on being contained in seat of reel from the effects such as braking force of seat of reel.Therefore, though the revolution of induction motor is corresponding with the output frequency of changer output, the peripheral speed of touch roll is not by the decision of induction motor revolution, but slow a little.So, bobbin on making touch roll and being contained in seat of reel the two contact and the occasion with the high-speed wind-up spinning under, it is big by 0.5～2% to set the output frequency of changer for use than as prescribed revolution driving induction motor output frequency, and the peripheral speed of the bobbin on making touch roll and being contained in seat of reel is consistent.
But, the drive manner of spinning take-up machine is high-speed wind-up only not, also have when the such seat of reel conversion of replace tubes automatically (, the replacement of silk volume), touch roll separates with bobbin on being contained in seat of reel and is in freely that contactless state is driven by revolution down, perhaps carries out low speed at start of run and hangs drive manners such as silk.Therefore, only adopt the output frequency only make changer to increase 0.5～2% specified value, when seat of reel change or when low speed is hung thread with regard to the too fast problem of the peripheral speed that touch roll is arranged.
Therefore, just a kind of spinning take-up machine that the CD-ROM drive motor of touch roll is carried out the controller for motor of controlled reset that is provided with is proposed, it is when seat of reel is changed, at touch roll be contained in bobbin on the seat of reel when being in contactless state, make touch roll become the regulation peripheral speed according to the output of the sensor of instrumentation touch roll peripheral speed.But,, thereby make the control complicated problems that becomes because during the conversion of each operative condition, the condition of controlled reset all changes.
Therefore another part controller for motor is proposed, when promptly calculating according to theory that setting high-speed batches respectively and the output frequency during the seat of reel conversion again.But because it is to calculate change frequency under the occasion of decision operative condition according to theory, thereby the problem that cannot use the peripheral speed that matches with operative condition correctly to drive touch roll is arranged.
The present invention makes for the problem that solves above-mentioned prior art existence, its objective is provides a kind of spinning take-up machine, it is that bobbin on driving touch roll auxiliaryly, making it and be contained in seat of reel contacts and during along with revolution, can accordingly, correctly set the peripheral speed of touch roll with the various drive manners of spinning take-up machine.
In order to address the above problem, the present invention takes following technical scheme:
A kind of spinning take-up machine, it be provided with seat of reel with motor driven, be contained in the contacted touch roll of bobbin on this seat of reel, the touch roll CD-ROM drive motor that drives this touch roll sent the controller for motor of controlling valu, it is characterized in that: the said motor control setup be bobbin and touch roll not under the contact condition, controlling valu when the peripheral speed of touch roll becomes certain peripheral speed detected as the control a reference value, according to this control a reference value control touch roll CD-ROM drive motor.
Spinning take-up machine of the present invention is characterized in that: the speed that above-mentioned certain peripheral speed comes down to and silk speed is consistent becomes the peripheral speed of touch roll in fact with silk is fast and to control a reference value when controlling valu is as high speed when consistent and detected.
