Description
The application is filing date: October 22, Application No. in 2005: 200580040793.9(international application
PCT/EP2005/011369), the division Shen of the application for a patent for invention of invention entitled " up-coiler work station " number it is:
Please.
Technical field
The present invention relates to a kind of up-coiler work station.
Background technology
Supply bobbin (textile tubes preferably produced on ring spinner) containing less amount of thread is at such volume
Recoil on the work station of machine thus form jumbo cross winding bobbin.In rewinding process, it is also directed to yarn defect
Yarn is monitored by point, and these Yarn Defect are cut, and is replaced by the silk thread joint looked as yarn.
In this case, due to various physical factors especially because in this rewinding process produce thread tension,
Winding speed under this so-called automatic cross winding machine runs is typically limited to less than 2000m/min.In other words,
In rewinding process (wherein, such as, take off silk thread by being positioned at the rotational line air ring of textile tubes above-head), effect
Sharply increase at the thread tension run on silk thread, especially all the more so in the last three/one stroke of pipe.
If not taking effective counter-measure, in the case of this during bobbin stroke, thread tension can increase to initially
The several times of thread tension, this considerably increases the risk of silk thread fracture.Owing to silk thread ruptures not only to cross winding bobbin
Quality adversely affect, and reduce the efficiency of this kind of automatic cross winding machine, thus tasted
Equipment is sent out in runin such, i.e. can improve supply bobbin backing-off performance in rewinding process by this equipment, but extremely
Few produced thread tension is positively retained under critical range.
In CH-PS669 177, such as describe that (described yarn tension is at pipe stroke for limiting yarn tension
During increase) this device.In this well known device, to the control of winding speed and therefore silk thread is taken
The control of lower speed is that the function of the remaining silk thread amount as supply bobbin is carried out.In other words, in the apparatus,
When pipe stroke starts, originally it is wound with relatively high winding speed, but the volume at the end of pipe stroke
It is reduced to non-critical level around speed.
In order to limit the thread tension in rewinding process, it has been proposed that bobbin is received central spindle design and becomes drivable,
Described supply bobbin is positioned at this bobbin in rewinding process and receives in mandrel.Such as in CH-PS542 781 with
Precision cross winding machine describes this rotatably mounted bobbin for supplying bobbin together and receives mandrel.In this reality
In example, bobbin receives mandrel and is connected to drive drum, this driving drum to be arranged on the constant rotation along machine by drive belt
Drive shaft on, and can be connected in drive shaft by magnetic coupling in a targeted way.When main by its winding
The diameter of shaft-driven winding bobbin (such as cross winding bobbin) reaches a certain size, thus there is the biggest silk
When line takes off speed, corresponding device guarantees that the bobbin reception mandrel supplying bobbin is revolved with the unwinding of silk thread in opposite directionly
Turn.
Although restriction just can be realized without corresponding measure by these well known devices or reduction thread tension is (described
Thread tension continues to increase in pipe stroke), but other unfavorable physical factor can not be eliminated, i.e. logical
Crossing in the rewinding process that these devices are carried out, silk thread takes off speed bigger change.Owing to silk thread intersects at winding
Traversing during winding bobbin and this silk thread of producing takes off the large change of speed can cause in rewinding process quite
Big thread tension peak value, this greatly limits the most attainable silk thread and takes off speed.In other words, run
Silk thread due to the traversing of silk thread thus producing during cross winding bobbin alternately relative to acceleration drastically
And deceleration, thus cause silk thread persistently change take off under speed by from supply bobbin taken off.In the case,
Speed difference may be up to 40%, and this depends on the silk thread corresponding feed angle on cross winding bobbin.
It is also known that such as open type rotor spinner or the spinning machine of friction-type spinning machine, it is taken off by relevant silk thread
Device takes off the silk thread produced in the spinning unit of these weaving looms, thus beneficially yarn parameter with constant speed
Keep identical, and silk thread speed is the most constant.
In the case, winding speed is less than the up-coiler winding speed when unwinding supply bobbin, is about it very
One of.
Also from up-coiler known in DE-AS22 15 003 or DE-OS20 18 375, their winding head is configured with
Being arranged in the silk thread above supply bobbin and take off device, and be configured with downstream unit, this downstream unit receives for temporarily
Considerable amount of silk thread, such as to allow to connect two the end of a thread, and without interrupting rewinding process for this.
At the device being used for the yarn supply in supply container is controlled described in DE-OS20 18 375
In, winding head is respectively provided with silk thread and takes off device, and this silk thread takes off device higher than the winding speed of coiler device by 10
Silk thread is taken off from supply bobbin to the speed of 30%.The silk thread taken off from supply bobbin is transported towards supply container at it
Entering ejector in the way of row under the monitoring of sensor, silk thread is transported in supply container by this ejector, and supply is held
The occupied state of device is the most monitored, and supplements when necessary.
The winding head of the up-coiler described in the DE-AS22 15 003 all has silk thread and takes off device, is configured with brush
The rotatably mounted silk thread on shape surface stores device and is involved in the driving drum of bobbin for friction-driven.In this example
In, all silk thread processing meanss of winding head are all acted on by common drive source.
