Description
Technical field
The present invention relates to a kind of Yarn lateral-movement device of winding mechanism of as described in the preamble, the weaving loom that is used to produce cross winding bobbin according to claim 1.
Background technology
As is known, in the production of weaving bobbin (particularly so-called cross winding bobbin), must satisfy at least two preconditions.On the one hand, must be used in the weaving bobbin that yarn is wound up on the cylindrical shell and rotate, and on the other hand, the yarn on the weaving bobbin that runs to rotation is traversed along the bobbin axis.Because in the production of cross winding bobbin, modern weaving loom is with high relatively winding speed running, therefore, transversing mechanism also must be in the position that can obtain the high speed of traversing.
In weaving loom industry, this transversing mechanism that the textile yarn at high speed is traversed is for a long time known, and describes in detail with many different embodiment in patent documentation.
For example, DE 43 10 905 A1 have described a kind of so-called belt thread-carrier.This belt thread-carrier has two band wire harness (belt strand) that move and be equipped with respectively a plurality of yarn entrainment devices (threadentrainer) in opposite direction, and the yarn that these wire harness at high speeds will run on the winding bobbin alternately is transferred to its opposite side from a side of winding bobbin.
Yet in this known belt thread-carrier, the verified yarn transmission in the yarn reverse zone is disadvantageous.In other words, in this belt thread-carrier, the yarn transmission often goes wrong.
In addition, particularly in the automatic cross winding machine of operation fast, extensively adopt the thread guide drum that forms groove drum, except yarn traversed, this thread guide drum also circumferentially drove cross winding bobbin simultaneously by frictional engagement.Yet, adopt this mechanism of for example in DE 42 37 860 A1, describing, can only reel with the cross winding bobbin of " reeling at random " form, in other words, adopt this mechanism, the coiling of cross winding bobbin is than along with bobbin diminishes in the increase of run duration diameter.Because under the situation of this yarn winding drum, no matter the diameter of bobbin how, always there is identical yarn transmission angle, so under some coiling condition, if do not take special measure, will produce the folded circle of so-called coiling, therefore, propose the method that a large amount of special folded circles disturb and avoided these folded circles of reeling.
Having the folded circle of can being scheduled to reel in order the to produce bobbin of (for example accurately reel or stepping is accurately reeled) must make the ratio that bobbin speed and yarn traverse between the speed keep constant or keep at least intermittently constant during bobbin is advanced.
Therefore, in order to produce bobbin, must make the driving of bobbin and being driven apart of yarn transversing mechanism with this coiling.
For example, the driving of winding bobbin and the wind2 that is driven apart of Yarn lateral-movement device have been described in DE 198 58 548 A1, DE 199 60 024 A1.These known wind2s have the bobbin driven roller by the single motor action respectively, but and the yarn transversing mechanism of independent drive.In the case, the yarn transversing mechanism of these known winding mechanisms has the yarn transfer arm.Also the driving of these so-called finger-like thread-carriers of describing in DE 198 20 464 A1, DE 103 32 399 A1 or EP 0 838 422 B1 is undertaken by the electrical motor single driver.By the shape of optimization yarn transfer arm, the mass inertia of these yarn traverse apparatus is minimized, thereby can produce very high frequency of transverse moving by this yarn traverse apparatus.
Yet, have been found that in the case, can cause vibration at the yarn of the relatively low yarn transfer arm place high-speed cruising of the quality of finger-like thread-carrier by the yarn transversing mechanism, can cause yarn transmission actual interrupt like this, thereby the quality of cross winding bobbin to be produced is descended.
Summary of the invention
Therefore, from above-mentioned prior art, the objective of the invention is to further to propose a kind of Yarn lateral-movement device of winding mechanism of the weaving loom that is used to produce cross winding bobbin, this traverse gear is equipped with the finger-like thread-carrier, thereby, on the one hand, can produce the high speed of traversing for moving yarn, and on the other hand, guarantee that the yarn transfer arm of finger-like thread-carrier between the yarn transmission period does not vibrate.
According to the present invention, realize this purpose by yarn transversing mechanism with the feature described in the characteristic of claim 1.
Favourable structure of the present invention is the theme of dependent claims.
Owing to adopted fixed buffer (the yarn transfer arm of finger-like thread-carrier supports thereon between the yarn transmission period), therefore shortened the drift of yarn transfer arm significantly, and this bending strength for the yarn transfer arm has positive impact, can not increase the rotor inertia of finger-like thread-carrier simultaneously.In other words, shock absorber according to the present invention has prevented that the friction of the yarn that moves from causing the vibration of yarn transfer arm in the yarn guiding trough of yarn transfer arm, and these vibration meetings produce very adverse influence to winding process.
In the case, (claim 2) is provided with shock absorber in an advantageous embodiment, and it is arranged in the back of yarn transfer arm along the yarn service direction.
In this class embodiment, guaranteed that the yarn transfer arm acts on constant but relatively little contact force owing to the yarn of operation on shock absorber, and therefore during yarn traverses, evenly supported.
As described in the claim 3, in an advantageous embodiment, described shock absorber is arranged such that the drift of yarn transfer arm shortens to about 1/3 of yarn transfer arm total length (L).This means that throw of lever (becoming effectively by the thread friction effect bending force thereon on the yarn transfer arm) roughly is reduced to 1/3 of its initial length; as mentioned above; this bending strength to this member has very positive effect, and can avoid destructive vibration.
According to claim 4 and 5, described shock absorber forms the annular arrangement section, and is fixed in the front side of motor housing of the motor driver of finger-like thread-carrier.In the case, the circular configuration of this shock absorber has been guaranteed all to provide very full and uniform situation in the whole width range that yarn traverses; In other words, the lever situation of yarn transfer arm for example keeps identical during yarn traverses.And the cirque structure of this shock absorber helps shock absorber is arranged on the circular motor housing of thread-carrier actuator.In the case, for example can this shock absorber directly be fixed on the respective holder of motor housing by suitable bonding.
As described in claim 6, obviously also it is contemplated that shock absorber is detachably connected on the motor housing.As described in claim 7, in the case, the shock absorber of being made by the corrosion resistant material with good sliding properties (for example polytetrafluoroethylene) is secured on the base, and this base for example is fixed on the motor housing by bolt etc.Because the mechanical load of shock absorber under the effect of yarn transfer arm is relatively low, therefore, such mechanism has in fact unlimited service life.Also can relatively economical ground produce the shock absorber that is coated with polytetrafluoroethylene, they can be worked under all operating conditions very reliably.
As described in claim 8, the yarn transfer arm of finger-like thread-carrier also is provided in an advantageous manner, it has and the corresponding sliding part of shock absorber.By this sliding part that preferably has polytetrafluorethylecoatings coatings, the friction drag between yarn transfer arm and the shock absorber is minimized.In other words, can further reduce friction drag between yarn transfer arm and the shock absorber.
