Description
Technical field
The present invention relates to the weaving loom with a plurality of stations according to claim 1 preamble.
Background technology
In textile industry, multistation weaving loom for example two-for-one twister or crank closer, ring spinner, open-end spinning machine has been known since waiting for a long time and the various different embodiments of this weaving loom at large is being described relatively mutually in a large amount of patent documentations.
Usually have a plurality of identical stations at this multistation weaving loom, they always drive by the belt continuous haulage gear extending longitudinally along machine jointly in the arranged in succession setting of the both sides of machine longitudinal axis and its work unit.
In two-for-one twister or crank closer, each station is the corresponding two-for-one twisting spindles that can rotate freely that is equipped with for example, wherein, in most of the cases use the tangential belt of the annular extending longitudinally along machine as the drive unit of a large amount of two-for-one twisting spindless for weaving loom, it is being arranged on above the driving wheel of main drive of machine end side operation and at weaving loom the other end guiding movement above deflecting roller in the weaving loom end.For the wharve of carrying two-for-one twisting spindles secretly by tangential belt at the duration of work of twisting thread, so-called driving belt hold-down roller also has been installed, it makes tangential belt be close to wharve with sufficiently high thrust or with enough angles of contact with guaranteeing reliable frictional fit.
It is imperfect that yet described drive system is proved to be in practice, especially with two-for-one twister or crank closer and ring spinner, be combined, in this drive system, always consume useless energy while on station, not producing yarn, that is to say, although, when having broken yarn or similar incidents on station, affiliated two-for-one twisting spindles or Yarn-spinning spindle still continue in company with driving.
For how reducing unwanted energy consumption, various different suggestions have been proposed in the past.For example advised the station of this multistation weaving loom or so-called pivotable spindle system all has been housed, belt perhaps all so is installed in the spindle zone of station and is lifted away from roller, that is, it can be lifted away from tangential belt where necessary from the driving wharve of relevant spindle.
Station with pivotable spindle system is for example known by CH-PS510753, DE-GM7529164 and DE-PS2452939., that is to say, station has a kind of spindle, and it is so configured and disposed, that is and, where necessary, for example, when broken yarn, the driving wharve of spindle can pivotable leaves the travel path of tangential belt.
A kind of pivotable spindle system has been described in CH-PS510753, wherein, but be provided with the pivotable supporting arm of manual adjustments on the pivoting bolt on the step rail that is fixed on the multistation weaving loom with limiting in the mode that can rotate, himself there is receptacle and take up the spindle that drives wharve for twelve Earthly Branches free to rotate.At this, the pivotable supporting arm also has stop device, and it can realize that pivotal arm and spindle drive wharve reliably to be positioned at place, two final positions.That is to say, at the first place, final position, spindle drives wharve to be close to tangential belt with sufficiently high thrust, meanwhile, at the second place, final position, drives wharve and tangential belt to keep location, spacing ground.
DE-GM7529164 has illustrated a kind of pivotable spindle system, wherein, is provided with rotationally sleeve in the dead eye of step rail, and it has hole with sleeve central longitudinal axis eccentric setting for holding the bearing arrangement of two-for-one twisting spindles.The sleeve driven under " pivotable enters off-position " meaning by spring element remains on place, Chu， operating position, operating position by stop device, and the wharve of two-for-one twisting spindles is close to supporting belt tangential belt.Stop device himself mechanically be connected on yarn detector by drag-line, yarn detector makes stop device unclamp in the broken yarn situation, result, and sleeve rotates and enters off-position by spring element, at this, the driving wharve of two-for-one twisting spindles does not contact with tangential belt.Also activated brake apparatus in the situation that rotatablely moves of sleeve, it makes the two-for-one twisting spindles braking in inactive state.
Similar pivotable spindle system is also known by DE-PS2452939.In this pivotable spindle system, yarn detector operates electromagnetism switch pulse sensor in the broken yarn situation, and its switch pulse not only makes the doff bobbin but also makes two-for-one twisting spindles quit work.That is to say, in the broken yarn situation, the wharve of two-for-one twisting spindles and belt tangential belt keep location, spacing ground.Auch, in the pivotable spindle system according to DE-PS2452939, also makes the two-for-one twisting spindles braking in inactive state simultaneously.
There is the device that special belt is lifted away from roller and for example in DE-AS1239966 or DE19549163C1, done relatively detailed explanation.At this, DE-AS1239966 has illustrated the twisting machine with station, and its spindle drives by the belt tangential belt extending longitudinally along machine as common.There is at least one belt and be lifted away from that the support of roller is corresponding to be arranged in the spindle zone in the mode that can limit rotation.
Where necessary, support and belt are lifted away from roller and start by supporting thread monitor, and like this with several angular turn, belt is lifted away from roller and makes tangential belt be lifted away from from the driving wharve of spindle, thereby tangential belt no longer contacts with the driving wharve of spindle.During support proceeds to, Electromagnetically-operating is braked the spindle brake in inactive state by spindle simultaneously.
The station of multistation weaving loom has been described equally in DE19549163C1, and it has the spindle that can drive by tangential belt.In weaving loom, corresponding rocking bar is installed equally near spindle on step rail, its endways side belt is housed is lifted away from roller and there is the brake apparatus on the driving wharve that can be contained in spindle.Being positioned at operating position at the duration of work of twisting thread by Spring driving (locates in operating position, belt is lifted away from roller and is not close to belt tangential belt) rocking bar can in the broken yarn situation, utilize cylinder pivotable like this,, belt is lifted away from roller and makes the tangential belt that goes in ring not contact the driving wharve, wherein, spindle is braked in inactive state by brake apparatus simultaneously.
Yet said apparatus all has such shortcoming,, in the broken yarn situation, perhaps the driving wharve pivotable of spindle is left tangential belt, this causes reducing the belt tension of tangential belt, and then cause the operation of multistation weaving loom to worsen, and then cause the produced yarn Quality Down of twisting thread in other words, perhaps in the broken yarn situation, tangential belt is owing to using belt to be lifted away from the roller additional belt tension of having loaded, and this has caused increasing the energy consumption of weaving loom and has caused having increased bearing load.
