Abstract
The take-off arrangement includes two rollers (10, 13) controlled from a single controller (12). One of the motors (14) is an asynchronous motor running with a small speed difference to the other due to electrical slip controlled by means of the voltage/frequency relationship. A sensor (15) provides a signal of the actual frequency so that the speed difference can be corrected. An Independent claim is also included for the process of controlling the speed difference of individually driven rollers by controlling the slip, one of the motors being an asynchronous motor. When the second roller (13) runs slightly slower than the first (10), e.g. for spinning partially oriented yarn with intermingling, the first motor (11) is a synchronous or a reluctance motor. Where the second roller has a higher surface speed, e.g. for spinning fully oriented yarn, the rollers are of different diameter to achieve a base difference, with fine control provided by electrical slip. In that case the first motor can be an electrically stiff asynchronous motor operating at constant slip.
Description
Technical field
The present invention relates to a kind of device that is used for spinning and at least one synthetic threads of coiling.
Background technology
For example by the known a kind of such device of DE4416136A1.
For the spinning and the synthetic thread of reeling, known devices has a device for spinning, driven first godet roller and driven second godet roller and a coiler device.This after by the spinning-nozzle of described device for spinning ejection fuse by pulling out by electric motor driven first godet roller.First godet roller is partly reeled by silk for this reason.Second godet roller that is placed on first godet roller is wherein adjusted the speed difference between first godet roller and second godet roller equally by Motor Drive.The speed extent depends on the yarn types that will produce.When synthesizing many multifilament threads, mainly be divided into part and extend silk thread and the full silk thread that extends by the production of thermoplasticity liquation.Part is extended the molecular structure that silk thread has a preorientation, and they need extend in second operation again.They are called as preorientation yarn (POY).In contrast, extending yarn (FDY) entirely is suitable for not having and is directly used in reprocessing again with extending.Also known, must between godet roller, set up a big speed difference in order to process the FDY silk thread.And the spinning of preorientation silk thread and coiling need be set up less speed difference between godet roller.For producing this speed difference of polyester POY for example in 0.1 to 0.5% scope.Require during production process to reach with high accuracy and to keep regulating the speed at this for each godet roller.Usually add a controller for each motor for known devices for this reason, make each motor to control by the given frequency of a definite speed.Therefore when each production process changes, control cost and irrespectively keep the same size with the speed difference size.
Summary of the invention
The technical problem to be solved in the present invention is, constitute a kind of device of above-mentioned form like this, can be when keeping relative degree of precision be implemented in small speed difference between driven first godet roller and driven second godet roller with low-down controlling cost.
Be resolved by following feature according to this technical problem of the present invention: be used for spinning and the device of at least one synthetic threads of reeling, it has a device for spinning, driven first godet roller and driven second godet roller, also has a coiler device, wherein said first godet roller and second godet roller are reeled at least in part by silk thread, and wherein said first godet roller and second godet roller are driven with a speed difference by the motor of subordinate respectively, wherein, be provided with a controller that is used for two motor, can be by this controller with a given FREQUENCY CONTROL motor, and one in the motor is made of asynchronous motor, and this asynchronous motor has a rotating speed slippage corresponding to speed difference.
A kind of like this theory of utilization of the present invention, the asynchronous motor with a given frequency drives also produces a small driving rotating speed thus because the rotating speed slippage that its operation principle produces produces a more small actual frequency.Therefore can need not additional control measure ground and realize speed difference with simple method, this speed difference is positioned on the order of magnitude of a rotating speed slippage.
In order to realize the adjustment possibility and the variation of speed difference, expansion structure of the present invention is particularly advantageous, wherein said controller has a transformable voltage/frequency characteristic, can control described asynchronous motor by this characteristic and be used to change the rotating speed slippage.Can influence the magnetization of described asynchronous motor by voltage for the characteristic of frequency, this will cause the variation of rotating speed slippage.Because therefore little crossing magnetization or hang down magnetization of the powerful property of the power permission of asynchronous motor can not adjust the rotating speed slippage than lossy ground.
For another particularly advantageous expansion structure of the present invention, described asynchronous motor is set a sensor, record actual frequency by this sensor.Described sensor is connected with controller by a holding wire, is therefore obtained the asynchronous motor slippage state of that adjustment by actual frequency and given frequency in controller inside, so that can directly adapt to desired speed difference by the voltage/frequency characteristic.Therefore for example can advantageously adjust because load variations in the inhomogeneities that run duration produces, makes actual frequency also make the peripheral speed of that driven godet roller remain unchanged during whole service basically thus.
Not only can drive second godet roller or also can drive first godet roller according to the asynchronous motor of the yarn types that will be produced by such driving.Depart from one under the situation that the lower actual frequency of given frequency drives at second godet roller and will realize a speed difference, the silk thread stress between this speed official post first godet roller and second godet roller reduces.Compare with second godet roller with higher peripheral speed driving at this first godet roller.
Increasing a little under the situation of stress at the expectation silk thread, is favourable by Asynchronous Motor Driving first godet roller.Therefore first godet roller is compared with second godet roller with a lower speed drive corresponding to the asynchronous motor speed slippage.
In order when driving godet roller, to make full use of the gamut of an asynchronous motor speed slippage as far as possible for the difference of regulating the speed, according to a favourable expansion structure regulation of the present invention, another motor is made of a synchronous motor or a reluctance motor.Therefore make one in the godet roller can be with speed drive corresponding to given frequency.
Also exist two godet rollers to pass through the possibility of an Asynchronous Motor Driving respectively.This be it is also noted that in the asynchronous motor one is " soft (weich) " as far as possible on electrical characteristics,, has a corresponding bigger rotating speed slippage that is, this slippage can be according to the voltage/frequency characteristic variations.Second asynchronous motor is " rigidity (steif) " on electrical characteristics in contrast, and it has very small rotating speed slippage, and this slippage is basic to have nothing to do with the voltage/frequency characteristic.
The adjusting of described asynchronous motor can advantageously realize like this, that is, and and frequency adjustment of Induction Motor Control of electricity " rigidity " and the asynchronous motor of electricity " softness " is regulated by the voltage/frequency characteristic.
For requiring the situation of big speed difference to have this method between first godet roller and second godet roller, that is, the elementary proving of speed difference is given by the housing diameter ratio of first godet roller and second godet roller.Therefore for example second godet roller can constitute with a housing diameter greater than the first godet roller housing diameter, makes to be adjusted at the higher peripheral speed of realization on second godet roller for identical frequency.For the elementary proving (Grundeinstellung) of accurate adjustment speed difference can use the rotating speed of asynchronous motor skid regulated.
Can additionally have the heater that is used to heat shell according to that production process first godet roller and/or second godet roller, so that can heat-treat to silk thread.
Be used in spinning and the methods of the godet roller that two of controls drive with speed difference when reeling at least one synthetic threads according to of the present invention, the motor of wherein said godet roller is by given FREQUENCY CONTROL, it is characterized in that the speed difference of described godet roller is adjusted by the rotating speed slippage of a motor that is made of asynchronous motor.
Especially be according to the unusual part of method of the present invention,, only need less control device in order between two godet rollers, to keep a speed difference with high accuracy.The speed difference that advantageously is included in second godet roller by the rotating speed slippage by the operation principle generation that an asynchronous motor can be considered to usually defective according to method of the present invention is regulated the inside.At first can advantageously realize littler speed difference thus.
At this preferably by to the given of the voltage/frequency characteristic of subsidiary controller with change the adjusting that realizes speed difference.The given frequency that provides respectively for different voltage/frequency characteristics changes the rotating speed slippage of controlled asynchronous motor.
Reached according to device of the present invention and especially to be used in processing according to method of the present invention and to be called as the synthetic thread of POY yarn.Can adopt polymer at this, as polyester, polyamide or polypropylene.

Be placed on second godet roller 13 in order to receive and store 9 one coiler devices 16 of silk thread.Silk thread 9 is wound into a reel 17 in coiler device 16, and it is formed on the Spulspindelspulspindel 18 of a rotation.
For pulling out from device for spinning 1 by first godet roller 10 and second godet roller 13 at the embodiment silk thread 9 shown in Fig. 1.Drive with a speed difference at this first godet roller 10 and second godet roller 13.Provide a given frequency f in order to drive 10 pairs of controllers 12 of first godet roller
SollPass through controller 12 with given frequency f by pilot 19.2
SollControl synchronous motor 11.Therefore first godet roller 10 has one corresponding to given frequency f
Sol1Peripheral speed.
Equally, in order to control by pilot 19.1 with given frequency f

Drive by asynchronous motor 14 corresponding to previous embodiment second godet roller 13.This asynchronous motor 14 is by control line 19.1 and controller 12 couplings connection, and this controller keeps pouring in sensor 15 by the holding wire 20.1 and the commentaries on classics of asynchronous motor 14 and is connected.The control of the asynchronous motor 14 of second godet roller 13 and adjusting therefore can be with reference to previous embodiment corresponding to aforementioned embodiment shown in Figure 1 realization.
Second asynchronous motor, 21 electricity of comparing first godet roller 10 with the asynchronous motor 14 of second godet roller 13 constitute " rigidity ".Therefore asynchronous motor 21 has a small relatively rotating speed slippage, and this slippage is irrelevant with selected voltage/frequency characteristic basically.Obtain actual frequency and pass to controller 12 for the peripheral speed of adjusting first godet roller keeps pouring in sensor 22 by commentaries on classics on asynchronous motor 21.In the comparison of carrying out on the controller 12 between actual frequency and the given frequency, so that correspondingly revise given frequency.Given Frequency Transfer through revising is given asynchronous motor 21, so that obtain a desired peripheral speed on first godet roller 10.
Owing to select D between the different shells
1And D
2Between first godet roller 10 and second godet roller 13, play the effect of a speed difference.Because the velocity setting difference that physical dimension produces is as the elementary proving of speed difference.In order to keep a selected speed difference, this speed difference for example is slightly higher than or is lower than elementary proving or equals elementary proving, controls and regulate the driving of second godet roller 13 corresponding to previous embodiment.Therefore can be constant by the given speed difference of the skid regulated adjustment of rotating speed and the basic maintenance of asynchronous motor 14.
Therefore can realize before coiling that at the embodiment shown in Fig. 2 the part of silk thread 9 stretches.In the time must will adjusting to greater than 0.1 to 0.5% speed difference, it is particularly advantageous that this method changes.
Structure of the foregoing description and application scenario are exemplary.The driving of first godet roller and second godet roller can exchange and make up mutually.First godet roller and second godet roller can repeatedly be reeled by silk thread equally.By selecting different housing diameters for example also can make two godet rollers, make speed difference inoperative with identical speed drive.Equally can be to setting transition roller free to rotate, so that with multi-turn guiding silk thread at the godet roller shown in Fig. 1 and 2.In addition, at least one godet roller has heater, by this device heating shell, can realize silk thread heat treatment thus.
