Technical field
The present invention relates to the described spinning machine of a kind of preface according to claim 1.Drive system can relate to the drive system of a kind of fine spining machine of any possibility in principle.
In some cases, separately fine spining machine drives that need can be in positive and negative both direction operation, so necessary reversible of direction of rotation.
Summary of the invention
The purpose of this invention is to provide a kind of above-mentioned fine spining machine, it can make corresponding fine spining machine drive with a certain direction operation with simple and reliable method, or moves with other direction.
According to the present invention, this purpose reaches like this, and promptly frequency converter is to be designed to a certain direction trigger driving and always trigger driving with the opposing party, and at least one control input separately is provided.
Arrange based on this, might realize the reliable conversion of fine spining machine driving between two kinds of direction of rotation separately with the effort of minimum.
In pressing an advantageous embodiments of fine spining machine of the present invention, the direction of rotation of driving can change by the control input, for example by changing at least one parameter of frequency converter (becoming the power inverter of interchange from direct current).Usually, it is enough only need to change a control input for a new frequency converter that maybe can change parameter.As a result, for example by such control input, a data record can be by serial transmission to frequency converter.Single order wire enough is used for starting.
In another advantageous embodiments, frequency converter is provided with two independent control inputs.
In a preferred practical embodiment, frequency converter is provided with and two corresponding two control inputs separately of opposite direction of rotation.In the case, two control inputs can start by a relay especially selectively.
Relay coil answers an idle running diode in parallel comparatively suitable.
Relay can be by machine the digital control output of central control unit advantageously start.
By among the suitable embodiment of fine spining machine of the present invention, relay comprise one with two conversion contacts that control input cooperates of frequency converter.This conversion contact preferably is located in the enabling signal line that is associated with frequency converter.
Direction of rotation separately can preestablish by an operating personnel's control module that is connected with the machine central control unit.
The predetermined of direction of rotation separately preferably finishes by separately a parametrization.
In a suitable embodiment according to fine spining machine of the present invention, the machine central control unit designs like this, promptly under the situation that the direction of rotation that drives changes separately, machine is stopped running.
The change that is used for to separately direction of rotation can also be set send signal or device shown.Signal or display unit preferably trigger by the machine central control unit.
If when being provided with other and being used in particular for starting the frequency converter that or several fine spining machines drive, then beneficially described other frequency converters of at least a portion are powered by common intermediate circuit, and common intermediate circuit can be powered with the frequency converter that this driving is associated by at least one by DC voltage.
Best, the central control unit of machine also is to supply by intermediate circuit, and particularly the central control unit of machine can connect by a DC/DC converter.
It need be temporary transient reverse driving at least that fine spining machine driving separately can relate to any its direction of rotation.
Therefore, this driving for example may be that a spindle drives.
Up to the present, the spindle direction of rotation that ring throstle all is designed to so-called " Z sth. made by twisting ", but also need the direction of rotation of so-called " S sth. made by twisting " in some cases.The Z of yarn twists with the fingers and the S sth. made by twisting relates to two kinds of mutual opposite direction of rotation, and this direction of rotation provides a Z-shaped yarn texture in one case, and the yarn texture of a S shape is provided in another case.
In order to realize the selection operation of the direction of rotation of Z sth. made by twisting or the direction of rotation that a S twists with the fingers with simple and the most reliable method, this frequency converter is to design by one of fine spining machine of the present invention preferably practical embodiment.It can start the spindle driving to twist with the fingers corresponding direction of rotation rotation with yarn Z, can start this spindle again and drive to rotate with corresponding another direction of rotation of yarn S sth. made by twisting.
Because the such result who arranges, might realize producing the reliable conversion of two kinds of methods of operation of Z twist yarn and S twist yarn with the effort of minimum.Driving separately relates to driving or a driving of doffing of a ring ingot, because these two kinds of drivings all need oppositely.
Driving separately also is particularly related to a drafting system and drives.Drive so preferably can carry out described drafting system like this, make the angle that it is scheduled to toward back rotation one fine spining machine is out of service after, as up to the present described in the still undocumented DE 100 11 190 by frequency converter of the present invention.This just guarantees in the machine stop motion and the drawing-off that can not make a mistake after resetting.The trend that oriented longer fuselage develops in the development of ring throstle.Usually the driver element of drawing rollers is arranged on the end of machine.Therefore the increase of drawing rollers length makes the torsion resistance of drawing rollers become very high, make fine spining machine out of service and reset after, slubbing or details part can appear in yarn, because two free ends of drawing rollers are being twisted into 30 ° more than in the distort process gradually.Therefore the drawing-off of mistake can appear in the fibre structure in drafting system at that time.This wrong drawing-off now can be by making drafting system avoid toward back rotation one predetermined corner after spinning machine is out of service, and this is by realizing with a simple and reliable method by frequency converter of the present invention.
Drafting system drives can be by realizing that by the such method of frequency regulator of the present invention promptly described drafting system drives, in the preset time after fine spining machine is out of service with a step or divide several steps to carry out inverted running.
In principle, the execution that drafting system drives also may be carried out by this way, promptly drafting system by to rear drive until till the drive end of drawing rollers gone back to a predetermined angle.

Fig. 4 is illustrated in the distortion process of drawing rollers under the different condition.
The specific embodiment
The drafting system driving 14 that starts by frequency converter 22 also is associated with input roller and middle roller, and the drafting system driving 16 that is started by frequency converter 24 then is associated with delivery roller.In the present circumstance, provide 8 drafting systems to drive 14,16 altogether.
The coil 32 of dally a diode 33 and a relay 31 is in parallel.
In existing embodiment, relay 31 comprises a conversion contact 13, and two control inputs 29,30 of device 20 match with changeing frequently for contact 13, and be preferably disposed on one with enabling signal line 15 that frequency converter 20 is associated in.
Direction of rotation separately can be scheduled to by operating personnel's control module 42 (see figure 2)s that are connected with machine central control unit 28.The pre-of direction of rotation carried out by parametrization separately surely separately.
Machine central control unit 28 preferably designs like this, makes under the direction of rotation change over condition separately of spindle driving 12, and machine is stopped running.
For signaling or showing that the change of direction of rotation separately can be provided with a device (not shown), signal separately or display unit for example can trigger by machine central control unit 28.
As in Fig. 1 as seen, drive 14 with drafting system, 16 and ring rail drive 18 frequency converters that are associated 22～26th, provide DC voltage by a public intermediate circuit 34, DC voltage is by at least one and one or several spindle driving 12 frequency converters that are associated 20.This intermediate circuit 34 also is central control unit 28 power supplies, and it is connected with intermediate circuit 34 by a DC/DC converter 36.Converter 36 is to be used for the high DC voltage that is applied on the intermediate circuit 34 is reduced to a lower voltage, for example is 24V in the case.
In order to regulate supply voltage, offer spindle and drive 12 frequency converter 20 and receive on the three phase network by a wave filter of selecting for use 38 and a transformer or reactor 40.
Fig. 2 represents the aforesaid operations personnel control module 42 that is connected with machine central control unit 28.
Between machine central control unit 28 and frequency converter 20,26 and the set-point value preparation device 46 (seeing Fig. 2 especially) that is associated with frequency converter 26 in the present embodiment, a data chainning 44 is arranged.The FC internal data chain 48 of a drawing-off that is used for drafting system and the FC internal data chain 50 (FC is the converter unit that comprises frequency converter) that is used for drafting system synchronous operation are arranged in addition.
In addition, also comprise an electronics drafting system gear in the present embodiment.For this purpose, two drafting system frequency converters 22,24 cooperate jointly in separately mode.Control module separately can be prepared plate by a set point especially and realize.Prepare plate by 28 pairs of set points preparations 46 of machine central control unit or set point and carry out the predetermined possible especially of data.Parametrization for example can realize by operating personnel's control module 42.
It is to realize by the additional control input 30 that one of frequency converter 20 is used for reverse rotation (REV) that other S twists with the fingers function.The reverse rotation of motor (REV) makes electric spindle drive 12 by frequency converter 20 and with reverse rotation.
The direction of rotation of frequency converter is by the conversion contact 13 of the relay 31 in the enabling signal line that is inserted in frequency converter 20 29 (FOR) to be imported in control to switch to control input 30 (REV).Therefore relay 31 is as a conversion contact element.The machine central control unit comes control relay 31 by a numeral output 11 that limits.
Operating personnel's control module 42 can comprise a menu item, and for example a changeable variable is used for being scheduled to the direction of rotation Z or the S of spindle.
So in each autoregressive parameter of frequency converter 20, just can determine forward direction (FOR) or reverse (REV) of direction of rotation.In all machine programs, guarantee the direction of rotation that keeps correct.
In principle, each frequency converter can not only drive 12 with fine spining machine and be associated, and can also be designed to be used for to trigger with the driving of a certain direction rotation and be used for triggering driving with the other direction rotation, and other spinning machines with at least one control input separately drive and are associated.In this frequency converter, for example also may be provided with once more and two corresponding two independent control inputs of direction of rotation, and can alternately start by a for example relay.No matter embodiment separately how, direction of rotation also can change by at least one parameter that changes frequency converter separately.
The spinning machine of each self-starting drives and also relates to a known ring rail that must reverse and the driving of doffing.
In principle, drafting system driving 14,16 can start by the frequency converter that designs respectively to drive 12 modes that describe in conjunction with spindle.
Machine central control unit 28 can comprise that here one drives oppositely control, this control influences frequency converter by this way or drives the relay be associated with drafting system, and promptly separately drafting system drives the certain amount of drive end counter-rotating that makes drawing rollers after fine spining machine is out of service.
The result be drawing rollers in static process, its free end is than the situation distortion that does not have above-mentioned measure or discharge a smaller angle.According to Fig. 4, drawing rollers 16a bears the maximum V1 of a distortion at its normal operation period at free end, and is when perhaps driving for both-end, then maximum in the distortion of machine middle part.After roller discharges,, the drive end of drawing rollers (left end) retracts to V2 if being held distortion angle.By in check reverse rotation or the release of drawing rollers at driving side, it bears one at left end and twists dv ' relatively as a positive release, and after drafting system partly discharged, an end on its opposite had the release dv of a passiveness ", its numerical value is less than two absolute difference V1-V2.The result makes and has reduced relative moving in the dispose procedure of drawing rollers after out of service, and wrong drawing-off is limited in the scope of allowing.
For the purpose of better understanding was provided, the qualitative process and the distortion value that have provided drawing rollers according to Fig. 4 were as follows:
The generally distortion on the drawing rollers total length L of V (angle distortion)
The distortion of V1 under stable operation
The distortion of V2 after discharging during the static process
The distortion of V3 under the releasing device influence
The release of dv ' roller left end (driving side) when having releasing device
Dv " release of the right free end of roller in the middle part of machine when dto is provided with driving for two ends,
The right-hand member of V1-V2 when not having releasing device discharges
More than explanation can be applied in the required layout of any driving on drawing rollers similarly.
If the drawing rollers of a unbroken length are provided with driving at its two ends, then so-called " free end " is half place of pact that is positioned at machine middle part roller length." free end " is interpreted as not having or only transmits certain location on the roller of inessential torque usually.
