Abstract
The invention relates to a textile machine, in particular to a preferential spinning machine, a twisting machine or a doubling machine which comprises a rotary ring (1) and a yarn balloon limiter or a yarn balloon limiting tube (2), so as to provide extra packages (8, 9, 10, 11) to save energy.
Description
The present invention relates to weaving loom,, preferably relate to spinning machine or twisting mill or doubling frame according to the characteristic of independent claims 1.
In the past in decades, confirmed already except such as open-end spinning, the false twisting air-jet spinning, air vortex spinning, or outside traditional rings spinning of friction spun yarn also can be set up some other spinning methods on market.Although the fact is, be proved to be the best approach of producing the yarn that is used for various actual final uses so far with the rings spinning with best in quality, weigh this method with the market share, run into huge difficulty, because new spinning method, be with obviously higher speed operation, therefore guaranteed obviously higher production capacity.
To this restriction of rings spinning, the time of decades had been discussed already, but had never obtained satisfied solution.Subject matter be rings, steel traveler and ballooning of yarn design; In other words, be this system itself.
To briefly explain these two problem domains below, rings-steel traveler problem at first is described, the high speed of service and/or big steel traveler weight have caused big centrifugal force, and have therefore caused big frictional force.Routine by material is selected, and has caused the height friction of metal and metal thus, has caused the tangible heating to less and lighter steel traveler and rings, and quick wearing and tearing more or less.As a result, the permissible velocity of the maximum of each steel traveler depends on material, and shape and application surpass this speed and can cause the overheated of described steel traveler and destruction.Therefore, to the speed setting of steel traveler restriction, and, to its service life and its performance quality having set restriction, even when using, also have described restriction in reasonable and correct mode.
Conversely, in fact described spinning method has three kinds of key factors to depend on this rotary speed of steel traveler: at first consistent with market with regard to the rotation of yarn, its transporting velocity should be high especially; Secondly, in spinning process, it is stable that yarn tension must keep, so that yarn qualities is consistent; The 3rd, the performance of yarn in the spinning triangle.
For above three kinds of values are produced positive influences, therefore, need be optimized the reasonable consequence of described design and the behavior of steel traveler especially.Have countless versions steel traveler variant can supply to utilize, it all shows special material and forms and/or shape under each situation.Although to described steel traveler speed, promptly transporting velocity is furtherd investigate, in fact described trial may produce some progress generally, but, has more clearly confirmed the overall restriction of steel traveler itself already.
Therefore, kinds of experiments is also arranged with regard to the optimization of rings.In order to overcome described rings-steel traveler problem, developed multiple different rings already, they rotate with described steel traveler, are called as rotary ring, for example, install with air bearing or roller bearing with the magnetic force rings.
A kind of system in described back of the magnetic levitation of spinning/twisting rings comprises a kind of variation of rotor-spindle principle.Usually, as the described spinning ring or the twisting ring of rotor, be positioned at the central authorities of described structure.Say in principle, some () magnet is installed around it, the distance that each interval equates.Each electromagnet only produces the power of described rotor rings suction to it.In other words, all electromagnet must produce the power that equates to described rotor rings, so that it is placed on described central authorities exactly, and it are remained there.
Being positioned on this rotor rings, and generally being fixed on above it, is the thread-carrier of decision yarn tension, the thread guide eyelet that is otherwise known as, the i.e. steel traveler of described front.Because in this case, described rings and " steel traveler " are connected to one another, and common rings-steel traveler problem no longer produces.On the contrary, because when starting or stoping,, set up cop starting spinning, and when yarn breakage the inertia force of described machine, produced some problems.
Just as mentioned above, second kind of spinning speed is limited in described ballooning of yarn.Term " ballooning of yarn " should be understood to the expression yarn from described thread guide eyelet to the place that is called tap (pig ' s tail) given figure to the stroke on described coiling pipe again, described yarn is twisted and is batched simultaneously.
The foundation of ballooning of yarn, and the tension force of yarn are the length by described air ring, and rotary speed is positioned at yarn qualities on the described ballooning of yarn and its distribution, and the frictional force decision of described steel traveler on described rings.If on from any point between the package of the outlet of drafting system and coiling yarn, described yarn tension has surpassed the breakaway poing of described yarn, will cause yarn breakage.Even described yarn is not fracture also, bigger tension force also can cause the forfeiture of stretching force, but and therefore cause the forfeiture of yarn working ability, this might can go wrong during particularly as weft yarn further having problems in the processing.Such yarn has lower value.
In order to reduce the power that acts on the described ballooning of yarn, for current rings spinning, the rings (referring to DE19944442) that adopts one or more air rings to narrow down usually, it makes described ballooning of yarn narrow down to one or more planes in the mode of round wire.Correspondingly reduced the power on the described ballooning of yarn.
According to DE19848752 or JP2001279538, the pipe that ballooning of yarn is narrowed down on long part is known.Say in principle, this narrow down be do not allow manageable because they have covered the major part of described cop.
Making the rings more effective additive method that spins is to be called as funnel spinning, the method for cap spinning spindle or hopper spinning.The part of funnel or cap spindle or hopper shape be used as respectively lid be placed on described coiling pipe above.By this design, the lower edge of described funnel, thereby or the thread-carrier of described funnel play and change direction and on described cop, batch yarn.Described yarn makes described air ring narrow down on the whole in the guiding of described funnel inside, has in fact avoided producing expanding.As a result, the same with all pipes that described air ring is narrowed down, the yarn bar generation effect between the lower centrifugal force counter extensioin device and the package of coiling yarn.The described problem of steel traveler friction also is resolved in this way.
But, described funnel must be to be different from the speed rotation of yarn package, and it can be accurately consistent with the coiling of yarn on described yarn package, and perhaps it must have other devices, and these devices can carry out self regulating and control to described system.Energy of being paid and expense are huge.
Because the coiling of described yarn fluctuates according to winding diameter, rotary speed difference and yarn tension difference are to produce by having spindle or funnel or the two yarn package.Under any circumstance, having the funnel of yarn package and/or the inertia of spindle all can have problems.
A common problem of the described air ring of restriction in top all solutions of mentioning is, described yarn is at full speed to stretch on the surface of described parts, for such as having low-melting polyacrylic thermo-responsive fiber type, may cause damage to described yarn or fiber.
Therefore, the problem that is caused by described prior art is that more effective spinning or twisting method are provided.According to the present invention, this purpose is that the weaving loom by independent claims solves.
Described solution comprises the combination of the spinning method that two kinds of technology are different.That is, on the one hand, having the rings spinning of rotating ring, on the other hand, is the method with air sphere limiter.This combination of two kinds of mature methods is used for replenishing their effective aspect, their defective of cancelling out each other simultaneously.
Below will the present invention will be described according to the example of embodiment, these embodiments are from any angle, all are not to be construed as exclusiveness, and are partly illustrated by accompanying drawing, and these accompanying drawings are regarded as example.
