Description
The application is: within 2005, October 22, application number are: 200580040793.9(international application no is: PCT/EP2005/011369), the denomination of invention divisional application that is the application for a patent for invention of " up-coiler workstation ".
Technical field
The present invention relates to a kind of up-coiler workstation.
Background technology
The supply bobbin (being preferably the textile tubes of producing on ring spinner) that contains less amount of thread thus on the workstation of such up-coiler, recoil and form high-capacity cross winding bobbin.In recoil process, also for yarn fault, yarn to be monitored, these yarn faults are cut, and by looking that the silk thread joint the same with yarn replace.
In this case, due to various physical factors, particularly due to the thread tension producing in this recoil process, the winding speed under this so-called automatic cross winding machine operation is restricted to conventionally lower than 2000m/min.In other words, in recoil process, (wherein, for example, take off silk thread by the rotational line air ring that is positioned at textile tubes above-head), the thread tension acting on operation silk thread sharply increases, especially all the more so in the last three/one stroke of pipe.If do not take actv. counter-measure, in the case in the process of bobbin stroke, thread tension can be increased to the several times of initial thread tension, and this has increased the risk of silk thread fracture greatly.Because silk thread fracture not only causes adverse effect to the quality of cross winding bobbin, and reduce the efficiency of the automatic cross winding machine of this class, thereby attempt for a long time developing such equipment,, can improve and supply with the backing-off performance of bobbin in recoil process by this equipment, but the thread tension that at least produced can remain under critical range.
This device that is used for limiting yarn tension (described yarn tension increases in the process of pipe stroke) has for example been described in CH-PS669 177.In this well known device, control to winding speed, and the control of therefore silk thread being taken off to speed be to carry out as the function of the remaining silk thread amount of supplying with bobbin.In other words, in this device, in the time that pipe stroke starts, originally reel with relatively high winding speed, but winding speed when pipe stroke finishes is reduced to non-critical level.
In order to limit the thread tension in recoil process, propose that bobbin is received to central spindle design and become drivable, described supply bobbin is positioned at this bobbin and receives in axle in recoil process.For example in CH-PS542 781, describe this for supplying with the rotatably mounted bobbin reception axle of bobbin together with precision cross winding machine.In this example, bobbin receives axle and is connected to drive drum by rotating band, and this drive drum is arranged on the axle drive shaft of the constant rotation of machine, and can be connected on axle drive shaft by electromagnetic coupling in target mode.For example, when the diameter of the winding bobbin being driven by its winding main shaft (cross winding bobbin) reaches a certain size, thereby while existing very large silk thread to take off speed, corresponding device is guaranteed to supply with the bobbin reception axle of bobbin and the unwinding opposite direction of silk thread and is rotated.
Although just can realize restriction or reduce thread tension (described thread tension continues to increase in pipe stroke) without corresponding measure by these well known devices, but can not eliminate other unfavorable physical factor,, in the recoil process of being undertaken by these devices, the silk thread speed of taking off has larger variation.The larger variation that this silk thread producing traversing of the coiling intersected coiled bobbin period of the day from 11 p.m. to 1 a.m due to silk thread takes off speed can cause sizable thread tension peak value in recoil process, and this has greatly limited attainable silk thread in practice and has taken off speed.In other words, thus the silk thread of operation is due to acceleration and the deceleration of traversing and hocketing relatively sharply in the process of cross winding bobbin producing of silk thread, so just causes silk thread under the speed of taking off changing, to be taken off from supply bobbin continuing.In the case, velocity contrast may be up to 40%, and this depends on the corresponding feed angle of silk thread on cross winding bobbin.
Also known case is as the spinning machine of open type rotor spinner or friction-type spinning machine, it takes off device by relevant silk thread and take off the silk thread of producing with constant speed in the spinning unit of these weaving looms, thereby be conducive to yarn parameter and keep identical, and silk thread speed is also constant.
In the case, winding speed is supplied with winding speed when bobbin lower than up-coiler at unwinding, be approximately its 1/10th.
Also from DE-AS22 15 003 or the known up-coiler of DE-OS20 18 375, their winding head disposes and is arranged in the silk thread of supplying with bobbin top and takes off device, and dispose downstream unit, this downstream unit is for the temporary transient silk thread that receives a great deal of, for example to make connecting two the end of a thread, and without interrupt recoil process for this reason.
The device that the yarn supply in subtend supply container of describing in DE-OS20 18 375 is controlled, winding head has respectively silk thread and takes off device, and this silk thread takes off device and take off silk thread from supplying with bobbin under than high 10 to 30% the speed of the winding speed of wind2.Under monitoring at sensor the way that the silk thread taking off from supply bobbin moves towards supply container at it, enter eductor, this eductor is transported to silk thread in supply container, and the occupied state of supply container is also monitored, and supplements where necessary.
The winding head of the up-coiler of describing in DE-AS22 15 003 all has silk thread and takes off device, disposes the rotatably mounted silk thread memory storage on brush shape surface and be involved in the drive drum of bobbin for friction-driven.In this example, all silk thread processing equipment of winding head are all subject to the effect in common drive source.
Summary of the invention
From above-mentioned prior art, the present invention is based on the object of improving the above-mentioned type up-coiler, in other words, is the workstation in order to optimize these up-coilers, thereby described workstation can be moved under significantly higher winding speed, and therefore the danger of silk thread fracture do not significantly improve.
According to the present invention, realize above object by the workstation as described in first aspect present invention.
Favourable structure of the present invention is the otherwise theme of the present invention.
In workstation according to the present invention, the working process that can simultaneously carry out by winding process being decomposed into two independences is eliminated above problem.In other words, be separated from each other with the winding process of the cross winding bobbin carrying out at wind2 take off the process of silk thread from textile tubes, make to take off silk thread from textile tubes and be not subject to the impact that silk thread traverses production intersected coiled bobbin subprocess.According to the present invention, take off device by silk thread and take off silk thread from textile tubes under the speed of the impact of the caused variation of not traversed, and in the way of moving towards cross winding bobbin at silk thread, silk thread moves through silk thread memory device, this silk thread memory device guarantees in the winding process of cross winding bobbin, namely running to traversing in process of silk thread on cross winding bobbin on the one hand, always exist enough wire length can be for utilizing, prevent on the other hand because the traverse variation of the silk thread speed that causes of silk thread adversely affects at textile tubes place and takes off silk thread.
Because yarn storage device substantially only needs to be involved in the silk thread amount matching with silk thread demand (this silk thread demand changes because silk thread traverses), thereby by non-critical ground managed storage amount, this point is very important, especially all the more so in the situation that of high-speed winding speed.
Owing to using according to silk thread memory device of the present invention, can greatly avoid high thread tension peak value, thereby can improve significantly the speed of taking off of taking off silk thread from textile tubes.
And silk thread memory device according to the present invention has been guaranteed to be always to provide minimum thread tension in the winding process of cross winding bobbin, this is extremely important concerning producing normal cross winding bobbin.Therefore, not only cause the improvement of the efficiency to up-coiler according to device of the present invention, but also caused improving the quality of the cross winding bobbin of completion.
