Description

The spinning machine that comprises compression drafting system
The present invention relates to a kind of spinning machine, be particularly related to an a kind of compression drafting system and spinning machine by the described infundibulate of independent claims characteristic, bell or hat air ring restraint device of comprising.
Prior art-air ring restraint device
Air ring restraint device on the application's meaning should be distinguished mutually with the air ring limiting part that comprises a rings and a steel traveler that known ring spinning method is used.The effect of above-mentioned parts is for example referring to Melliand Texile Reports, 3/1989,159ff page or leaf.
Using infundibulate, air ring restraint device or thread guides bell or cap has been known since the development of industry spinning method.In addition, the spinning of known for a long time these devices of use or parts can overcome the low problem of ring spinning method productivity ratio of using rings and steel traveler.Owing to will boost productivity, many kind combinations of the various industrial parts that people propose now at first should actually be used on spinning machine and/or doubling frame, but do not succeed up to now.In some cases, the embodiment that is proposed for example because complex structure and/or because of produce ballooning of yarn or use steel traveler to cause compare with known ring spinning method there is no much advantages and just abandoned in advance-this respect is for example referring to US1519663 or DE-B-1053365.But the example of this class significant disadvantages-this class combination can be referring to following document for other embodiment:
GB631838,1948
Yarn introduces on a hollow spindle that flier (cylindrical flier) is inner, maintenance contacts with the flier inner surface, and the thread guides on the flier lower end is chosen in this contact, and yarn turns to by this guiding piece, and reel for yarn is around going into bobbin then.This hollow spindle is driven.This GB patent does not almost relate to the spinning process requirement that will satisfy.
DE-A-3046180,1980
This patent relates to the use of " element that is used to twist ", wherein bell-shaped piece and flier is illustrated flier shape bell-shaped piece as these examples of members.Be fed to bell-shaped piece inside and avoid forming air ring by being passed in the opening that is provided with on the spindle axis of prolongation from the yarn of drafting system.The problem of invention DE-A-3046180 is that the cop that yarn is wound on variation in diameter is on the yarn package.Therefore draw different bell-shaped piece velocity amplitudes.DE-A-3046180 proposes consider the drive unit of these problems.
Many improvement recently are derived from DE-A-3400327 in 1984.According to DE-C-3400327, the spindle top of spindle top spinning apparatus supports to free to rotate, is dragged by spindle on yarn, wherein, has a yarn to be directed to thread guides on the spindle top outer surface on the pivot center of spindle top.Therefore, yarn is at spindle top cap coiled on one's body, thereby carries bell-shaped piece and do not form the air ring of known type with driving style.For guaranteeing that ballooning of yarn is inhibited, further proposing spindle top should be elongated as far as possible.In an embodiment (Fig. 2), propose thread guides and should be embodied as the well known device that can suppress air ring.According to DE-A-3400327, this class device can be embodied as spinning finger or spinning crown, and they are provided with guide eye on the spindle top, and this guide eye is above spindle is tight.
The details of the effect of this spindle top structure can be referring to DE-A-3741432 in 1987.Therefore the winding speed difference, can on the spindle top outer surface, be compensated in the curl motion process at yarn by the difference that is wound into the yarn tension that cop causes.The pitch of these screw linees changes with yarn tension.Because obviously this moment, this method was not enough to overcome the problem that yarn tension changes, DE-A-3741432 also proposes to reserve the free space that can form ballooning of yarn between yarn import and yarn outlet in spindle top.Use the spinning process advantage of ballooning of yarn in other words and needn't accept its shortcoming.
Previous EP-A-225660 in 1985 has also proposed the idea of preferably little ballooning of yarn.This patent proposes following requirement to spinning unit:
-should guarantee that drafting system exports the optimum value that goes up " spinning tension " in so-called " spinning triangle ";
-no matter select what kind of spinning tension, should be able to improve " winding tension " that produce best cop, wherein
-under more speed and useful cop size, should further guarantee best spinning and winding tension.
According to EP-A-225660, the described device of DE-A-3400327 can't satisfy these requirements, can not control spinning tension (in the drafting system exit) and winding tension (when being deposited on the bobbin) respectively according to DE-A-3400327 especially.According to EP-A-225660, a solution is a control device of rotatable spindle top being made the size of determining ballooning of yarn and yarn tension.This control device is the open tube that does not hinder generation air ring between drafting system and control device in the upper end.The size of air ring should be guaranteed required spinning tension.But EP-A-225660 does not provide any actual solution.
Contents known about the effect of the described device of DE-A-3400327 also can be referring to DE-C-3741431 in 1987.Patent according to the back is described, uses by the described device of DE-A-3400327 and can obtain the speed that per minute 40,000 changes, and wherein, the apparent certain deviation at the yarn that so is spun into concerning ring spun yarn is that new yarn is remarkable crinosity.Therefore DE-C-3741431 proposes to be provided with a bundling piece between drafting system and spindle top.The rove that boundling is not twisted can reduce the triangle that spins, thereby reduces to act on the centrifugal force on the fiber.The expansion that therefore need prevent fiber end increases.
Recently, DE-A-19938493 proposes " around the rotational support pipe of its motion fiber being twisted by yarn " heavily again.Use this twisting should be able to " from the enough guiding at a distance of cop " yarn.DE-A-19938493 clearly mentions DE-C-3400327, the failure attribution of previous suggestion in " under the higher spinning speed that the spindle top spinning apparatus is realized, the centrifugal force that acts on the yarn increases, thereby forms, and reduces the how outstanding fiber of yarn qualities.”
According to DE-A-19938493, for addressing this problem, can use so-called " compression drafting system ", suppress outstanding fiber greatly, thereby when improving speed of production, obtain good yarn qualities first by combination compression drafting system and stay pipe with this drafting system.According to DE-A-19938493, this pipe and cop are provided with its drive unit in addition, and the speed of this two drive unit is controlled respectively.Like this, can regulate the speed difference of this pipe and cop arbitrarily.Thereby can be adjusted in the yarn tension that passes to the cop transition from stay pipe.
In addition, can draw a kind of method from EP-B-947617, wherein, by the fiber roving of drafting system output through boundling, the twisting back is with ring spinning apparatus coiling and do not generate ballooning of yarn or the minimizing ballooning of yarn.Because ring spinning apparatus is set, thus these embodiment do not have air ring restraint device on the application's meaning or thread guides but shown in DE-A-3400327 spindle top.
At last, in the disclosed a kind of spinning method of using balloon controller of WO97/32065, the yarn that the working surface of this balloon controller is carried secretly directly passes on this pipe from this working surface as the rotation split ring that expands under centrifugal action.Principle according to the WO97/32065 scheme, yarn is expanded to one and rotates split ring under action of centrifugal force, yarn is constantly imported in this rotation split ring by this ring itself, and yarn is constantly withdrawed from from this ring by this ring and the relative motion of rotating spindle then, is wound up into then on this pipe.This rotation split ring or be restricted diametrically and also possible space be shaped or in free space, rotate.
Prior art-compression drafting system
So-called " draw zone " of use after main drawing area is for some time known, for example referring to DE-A-857168.Requirement also is known at main drawing area or at outlet roller place boundling rove, for example referring to DE-B-1178749.
At least be the boundling method that is used in the success on the cotton yarn be just had in nearly ten years-for example referring to Melliand Texile Reports, 2000 3/133ff. and 2002 6/405ff. and International Texile Bulletin, 1/2002,42 and 43 page.
The most successful so far boundling method mainly uses pneumatic (air force) power to obtain the boundling effect.Also having and use mechanical force, is the DE patent application 102004020984.7 that the EP patent application 4018817.9 of 09.08.2004 and the applying date is 23.04.2004 referring to WO 03/95723, the applying date for example.
The present invention
The present invention is based on following knowledge: combination compression drafting system and infundibulate, bell or hat air ring restraint device or thread guides have many good qualities, and then are wrong but the described stay pipe of DE-A-19938493 is used as these parts.The present invention is also based on following knowledge: spinning tension and winding tension all are extremely important, but determine that with the other ballooning of yarn of spinning triangle spinning tension can't draw good result.
With the immediate prior art of the application be that DE applies for 199 38 493.This application discloses a spinning apparatus, comprises the thread guides of compression drafting system and the stay pipe form that is upside down in the spindle top, and yarn is provided with the deposition bobbin on this spindle outside, thereby spins rotation.
There are some problems in the prior art.On the one hand, the free looping on stay pipe causes very big friction on the outer surface.Therefore the yarn made from this method is remarkable crinosity for the product that the boundling spinning process that uses no stay pipe obtains, and promptly the filoplume degree is identical with common ring spinner.This makes angry especially, because the client, cotton mill in other words will be for spinning machine with compression drafting system, pay a lot of extra charges for the filoplume degree of the yarn that will spin is reduced to minimum especially.
Secondly, it is too many that spinning tension and winding tension differ.Therefore, yarn becomes undue and extends between stay pipe and deposition bobbin, and its elongation at break reduces.Under high rotating speed, it is more uncontrolled that yarn becomes, thus in spinning process the cop thickening: yarn rises, displacement fully under centrifugal action at last.
Therefore, the artificial effect that improves the stay pipe of yarn qualities and speed of production conception of this invention is that speed of production improves, but the yarn qualities proof has stood the technology of operation on this device.
Therefore the purpose of this invention is to provide a kind of than known boundling spinning or the yarn-twisting machine spinning machine that not only speed of production improves but also yarn qualities also can improve.
For realizing this purpose, the present invention makes up the air ring restraint device in compression drafting system and downstream, and this air ring restraint device is designed so that yarn is placed on the deposition bobbin from this device inside.This class device is for example known by the spindle top spinning.
Spinning or twist yarn that this class is called the spindle top spinning are a kind of methods that improves the efficient of ring spinning or twist yarn.The element of the type of spindle top or funnel is upside down in deposition bobbin top at this moment.Deposit at this cloth, base, the breach on the base or any type of thread guides of spindle top are as the steering gear of yarn being passed on the deposition bobbin in the spindle top or on the spindle top.Yarn most of at least but preferably all on the spindle top inner surface, be directed can be most of at least, prevent that all air ring from broadening in a preferred embodiment.Therefore, the same with all control device that air ring is narrowed down, act on drafting system and the yarn that will reel between thread segment on centrifugal force reduce.The problem of steel traveler friction so also is resolved.The support yarns of guiding piece own, the i.e. whole absorption centrifugal force of guiding piece.
