Description
Technical field
The present invention relates to a kind of knitting machine that is used to process rove.The invention still further relates to a kind of method by rove manufacturing needles fabric.
Background technology
Propose in a different manner in the past, knitwear are directly processed by staple fibre or rove.The knitting processing of the non-rotary fiber sliver basically of the fiber through having approximate parallel orientation, the knitwear of processing have very " soft hand feeling ", and have very high wearing comfortableness.In addition, these knitwear can be processed in the lowland by cost very much, because saved the intermediate steps that traditional yarn is made, the winding again when promptly yarn forms, reels and needs.
For example at US-A-3, propose in 877,254, staple fibre is supplied with the pin of knitting machine.Described there device is bright with the as an exampleBSEMGVR takeN-PSVSEMOBJ of circular knitting machine.Extracted by the wheel that is provided with hook under the situation of formation annular at the staple fibre that aligns in a parallel manner on the hairbrush, and be delivered to the pin of circular knitting machine, staple fibre is knitted into knitwear by said circular knitting machine.Intertwined point in the mesh gives knitted cloth required intensity.Mention that also the boost line in the yarn in addition also can be knitting by together.
A kind of circular knitting machine has been described in WO 2004/079068; The knitting point that rove is supplied with said circular knitting machine replaces the finished product yarn of from yarn tube, extracting out that joins with each knitting spot correlation; Said rove is stretched to the fineness of expectation in tensioning system, and supplies with knitting needle then.To forming, the right different peripheral speed of said roller is confirmed the degree that stretches to this tensioning system by the roller of feed and discharging, and therefore confirms the refinement degree of rove.
The rove that is stretched strengthens after leaving tensioning system, so as roller that can the bridge joint discharging to and knitting needle between spacing.According to WO 2004/079068, this realizes through false-twisting device.The temporary transient yarn that so produces should have enough intensity, so that also can carry in bigger a little spacing.False twisting is being decomposed to the path of knitting point once more, makes fiber get in the knitwear of being processed by knitting needle with the position that is parallel to each other basically.
What also proposed is that the rove that is stretched guides through spinning head after leaving tensioning system, so that give its intensity enough for being delivered to knitting needle.Different with false-twisting device, the rove that is stretched strengthens in spinning head enduringly, makes to detect the stranded of yarn at the knitting needle place.
When roving-drafting, produce dust and fiber hair in large quantities.This can cause tensioning system relatively promptly contaminated, and must often clean.If do not clean, possibly occur so polluting the fiber sliver that said pollution causes stretching fault and further causes being stretched unevenly.In tensioning system, because the roller of roller right different circumferential speed, especially discharging is to receiving very high wearing and tearing.This causes must polishing or the more lining of roll change again in short relatively interval.The enhancing in order to be delivered to knitting needle from tensioning system of the rove that is stretched is debatable equally.This can always occur the fault relevant with the of short duration interruption of the fiber sliver that is delivered to knitting needle once more.Especially in the rove that in false-twisting device, strengthens, this can cause the unacceptable hole in the knitwear of being processed by knitting needle.
Summary of the invention
The objective of the invention is to, improve a kind of knitting machine that is used to process rove as follows, reduce fault rate with alap degree.Should prevent to be delivered to the pollution and the inhomogeneities of the fiber sliver of knitting needle.Should prolong service intervals.Should prevent to be delivered to the interruption of the fiber sliver of knitting needle.At this, also should be possible be, on meaning according to the present invention the repacking existing knitting machine.
The realization of this purpose is a kind of knitting machine that is used to process rove.According to the present invention, this purpose also is achieved through a kind of method that is used for being processed by rove knitwear, and said method has according to method step provided by the invention.Improvement project of the present invention and/or favourable embodiment deformation program are the content of this paper.
The present invention proposes a kind of knitting machine that is used to process rove, and said knitting machine has the knitting point of some, supplies with in the rove preparation facilities rove through handled to the pin of said knitting point respectively, so that produce knitwear thus.The rove preparation facilities is positioned at before the knitting point, but said rove preparation facilities has respectively and is used for rove is resolved into filamentary decomposer and the friction-type spinning apparatus of yarn of stable feed that is used for filament is processed into the fineness of expectation.
The knitting machine that replaces in the prior art oneself to know is employed to have input roller with different peripheral speed rotations to the drafter right with outlet roller; The present invention proposes; Be arranged on knitting some rove preparation facilities before, said rove preparation facilities has decomposer and friction-type spinning apparatus respectively.The excessive wear of roller lining can not appear.Cancellation is owing to be the more shutdown of roll change of maintenance purpose.In fact rove preparation facilities with decomposer and friction-type spinning apparatus does not have uncontrollable fiber hair.Therefore prevented the pollution of decomposer and friction-type spinning apparatus.Therefore also prevented the inhomogeneities of yarn of pollution and the enhancing of rove.These install rare fault and take place, and in fact the interruption to the pin delivered yarn of knitting point does not take place.
For each knitting point, be provided with rove preparation facilities separately in principle.What especially proof suited under limited workplace situation is that per two knitting points are associated with an independent rove preparation facilities.
Rove for example supply with through feed roller to or the feed tube carry out, said feed roller to or the feed tube with cooperate with the feeder trough that flexibly pushes towards the feed tube.
Decomposer preferably includes and is arranged on having from the decomposition roller of tooth, brad or the analog of circumference protrusion in the housing, and said housing has feed orifice and the fibre guide channel that is used for filament is flowed to the friction-type spinning apparatus.This decomposition roller is well-known and through overtesting in open-end spinning, and has high reliability and long service life.
In order to remove, suitably can constitute the drain outlet on the housing of atwirl decomposition roller attached to the contaminate particulate on the rove.This drain outlet is led between feed orifice and the fibre guide channel hole, and can close through shutoff device.The other end of drain outlet can be connected with negative pressure source.Suitably use rotating type impeller or similar device as shutoff device.
The friction-type spinning apparatus comprises at least one friction-type spinning cylinder, said cylinder can be rotatably set in little spacing fibre guide channel outlet below.Friction-type spinning cylinder is that oneself knows in prior art, and for example is used to process coarse yarn, and said coarse yarn is used to process Floor wiper cloth or thick ornament materials.The yarn of processing by friction-type spinning cylinder has sufficiently high conveyings stability, so that also can be under situation about not breaking, on long distance, be transported to the pin of knitting machine from the friction-type cylinder that spins.
But the yarn by unique friction-type spinning cylinder manufacturing stable feed is possible.Another alternative embodiment deformation program of the present invention proposes, and friction-type spinning cylinder forms wedge-shaped crevice with the supporting cylinder that direction of rotation that can be identical is rotated, and said wedge-shaped crevice is with the extension below the outlet of fibre guide channel of little spacing.But the formation of the yarn of beginning stable feed in the wedge-shaped crevice of two cylinders.At this, supporting cylinder also can constitute internal solid cylinder, perhaps constitutes another friction-type spinning cylinder.
Attested embodiment deformation program proposes, and friction-type spinning cylinder has through the rotatable sleeve of punching and is arranged on the static guide cylinder in this sleeve.On the shell surface of static guide cylinder, be provided with at least one guide slit of extending along the longitudinal direction of friction-type spinning cylinder, affiliated guide slit can be connected on the negative pressure source.The filament of on sleeve, carrying remains on through negative pressure in the zone of longitudinal edge of guide slit, but and is wound into the yarn of stable feed through the sleeve of rotation.Under the situation of unique friction-type spinning cylinder, negative pressure is used to enough prevent that fiber from leaving the zone of guide slit.Under the situation of friction-type spinning cylinder and supporting cylinder combination, the beginning yarn forms in the wedge-shaped crevice of two homodromal cylinders.At this, guide slit is towards wedge-shaped crevice.Under the situation of two friction-type cylinders, in the wedge-shaped crevice of two cylinders, carry out yarn equally and form.At this, two guide slit are arranged in the zone of wedge-shaped crevice and face each other.
Extend obliquely through the longitudinal axis of guide slit with respect to friction-type spinning cylinder, the yarn that helps to produce is along the conveying of guide slit.
But the yarn of the stable feed that produces preferably through discharge roller to carrying, in the prolongation of said discharge roller to the extension that is arranged on guide slit with being right after friction-type spinning cylinder.At this, suitably in the prolongation of the extension of guide slit, carry out the extraction of yarn, so that avoid because direction changes the broken string that causes.
As in the circular knitting machine, the outfit that is used for processing the knitting machine with rove treating apparatus of rove can realize that equally said rove treating apparatus comprises decomposer and friction-type spinning apparatus respectively at flatbed knitting machine.It is suitable especially that use in circular knitting machine confirms.
Be to produce knitwear by rove according to the method for the invention by knitting machine; Wherein supply with in the rove preparation facilities rove to the pin of knitting point respectively through handled; So that produce knitwear thus; It is characterized in that, rove is resolved into filament, but and be wound into the yarn of stable feed of the fineness of expectation through the friction-type spinning apparatus.Use has obviously less fault rate and replaces tensioning system with the decomposer and the friction-type spinning apparatus that need less maintenance to expend.Therefore can reduce the downtime of knitting machine.In the method according to the invention, fiber hair in fact no longer occurs, thereby can avoid facility and the yarn of being weaved to be polluted.The yarn that is wound into by filament with the friction-type spinning apparatus is very uniform, and has enough conveying stability, so that can yarn be delivered to knitting needle from the friction-type spinning apparatus.The yarn of producing is to have stranded real yarn, said stranded can on knitting needle He in the knitwear, the confirmation.Therefore broken string almost no longer appears.
The rove of for example extracting out by the flyer spindle spool suitably through feed roller to or supply with the interactional feed cylinder of spring-loaded feeder channel and to decompose roller, said decomposition roller is separately positioned in the housing and can rotates apace.Be protruding with tooth, brad or analog from each outer circumference surface that decomposes roller, rove resolved into filament by means of said tooth, brad or analog.At last filament is delivered to the friction-type spinning apparatus in downstream.
When rove is resolved into filament, preferably separate dirt particulate, and transport through air-flow.Therefore environment division is less polluted, and can produce the yarn of cleaning by the friction-type spinning apparatus.
Dirt particle is transported through the dirt passing away that is connected with negative pressure source.Dirt passage separates through shutoff device and negative pressure source, make to discharge by the isolated dirt of filament, but negative pressure source is inoperative in the dirt passing away.Shutoff device for example is impeller or similar device.
By means of suction air filament is delivered to the friction-type spinning apparatus through fibre guide channel, the end next-door neighbour friction-type spinning apparatus of affiliated fibre guide channel.Therefore, prevent that undesirable penetration air from getting into fiber channel.
The suitable yarn that is wound into stable feed by means of friction-type spinning cylinder of filament.This type friction-type spinning cylinder is that oneself knows at the thicker yarn that preparation is used for mop or thick ornament materials for example, and it has high reliability.Friction-type spinning cylinder has the rotatable sleeve and the static guide cylinder that is arranged in this sleeve of perforated; Said guide cylinder has at least one guide slit of extending along the longitudinal direction of friction-type spinning cylinder on its shell surface, and can be connected on the negative pressure source.Filament places in the zone of the guide slit on the rotatable sleeve of perforated, but and is wound into the yarn of stable feed at the longitudinal edge place of guide slit.
The yarn preparation can realize by enough independent friction-type spinning cylinders.A kind of method deformation program proposes, and friction-type spinning cylinder forms wedge-shaped crevice with the supporting cylinder that rotates with identical direction of rotation, in said wedge-shaped crevice, carries out yarn then and forms.Supporting cylinder can have imperforated surface, perhaps constitutes another friction-type spinning cylinder.At this, guide slit is always towards wedge-shaped crevice.
The yarn that strengthens by friction-type spinning cylinder suitable by discharge roller in the prolongation of the extension of guide slit, extracting out, and supply with the knitting point that is associated.Through in the prolongation of the extension of guide slit, extracting the yarn that forms out, avoid direction too much in conveying to change.
The yarn that in the friction-type spinning apparatus, produces is knit into knitwear in knitting machine.Can use flatbed knitting machine or circular knitting machine as knitting machine at this.
Another suitable deformation program of the present invention has storage line apparatus and thread supplying device between the pin of fiber production device or decomposer and friction-type spinning apparatus and knitting machine.Storage line apparatus and thread supplying device can constitute the active yarn-feed device, and said active yarn-feed device can synchronously move with the driving of knitting machine, and always provides the fiber sliver of the continuous enhancing of constant basis.In another alternative embodiment deformation program, storage line apparatus and thread supplying device constitute the memory-type yarn feeder, and said memory-type yarn feeder always provides the material of knitting machine aequum.The driving common and decomposer and feeding device of memory-type yarn feeder synchronously moves.It also can be provided with optionally as the active yarn-feed device or as the yarn feeder of memory-type yarn feeder operation.This permission, (energetically) or supply line off and on optionally continuously is for example so that change between level and smooth knitwear (single jersey) of preparation or preparation jacquard knitted fabric.As far as weaving/spinning process, the driving of knitting machine and decomposer and friction-type spinning apparatus can be decoupled fully each other.Therefore, under the situation of static knitting machine, but at first be woven into the yarn of stable feed by decomposer and friction-type spinning apparatus.This yarn is for example manually supplied with the fanging noz(zle) or the thread-carrier of knitting machine through yarn feeder.And then knitting machine brings into operation.
Under the situation of circular knitting machine, integrated the showing of yarn feeder is favourable just, because decomposer and friction-type spinning apparatus are arranged to have big spacing with the knitting needle cylinder thus, and therefore is arranged on the circumference far away.This is favourable to the work-yard situation.

Fig. 1 schematically illustrates the schematic diagram of the circular knitting machine of prior art, and said circular knitting machine is equipped with tensioning system, so that can be directly by rove manufacturing needles fabric.Circular knitting machine representes with Reference numeral 1 on the whole, and has syringe 3, on said syringe, for example is provided with to have movably pin 4, especially 48 of the ligulate pin or 96 knitting points.Pin 4 is directly processed rove Y, and said rove is for example supplied with knitting point 2 as drawing-off sliver or conduct from jar from the flyer spindle rove of flyer spindle spool 5, and said flyer spindle spool can be installed in the creel of circular knitting machine 1.At this, knitting point 2 is regarded as like upper/lower positions, is transmitted to the knitting needle 4 that is arranged on the syringe 3 at ribbon Y on the said position.
Will be in tensioning system 6 drawn and supply with pin 4 according to WO 2004/079068 by the rove Y that twist yarn mechanism 10 gives its false twisting, said pin is processed knitwear by the rove Y of drawn.Twist yarn mechanism 10 is for example for twisting with the fingers nozzle, and the desired stranded of the fiber sliver Y of drawn realizes by compressed air in said sth. made by twisting nozzle.According to WO 2004/079068, false twisting is being decomposed in the way of knitting needle 4 once more, and fiber is knitted in the knitwear with the position that is parallel to each other basically.Also once propose, the rove of drawn strengthens by spinning head continuously, so that only eliminate the transportation problem of the fiber sliver that keeps together through false twisting.
Fig. 2 illustrates the sketch map of the knitting machine that constitutes according to the present invention, and knitting machine is represented with Reference numeral 21 on the whole.For example it also is a circular knitting machine, and said circular knitting machine comprises a plurality of knitting point 22 with knitting needle 24, and said knitting needle is arranged on the syringe 23 movably.Knitting machine 21 constitutes and is used to process rove Y, and has rove preparation facilities 26 for this purpose.In Fig. 2, unique rove preparation facilities 26 only is shown, before said rove preparation facilities is positioned at knitting point 22 based on reason clearly.In rove preparation facilities 26; Adopt decomposer 30 and the friction-type spinning apparatus 40 that is right after this decomposer 30, replace from well known in the prior art by with the pinch roll of different peripheral speed operations to the tensioning system formed and be serially connected in being used to after this tensioning system strengthen drawn fibrous material be generally pneumatic device.
Extract out in the flyer spindle spool in the creel that can be arranged on circular knitting machine 1 that rove Y for example never is shown specifically, and press the feeder channel 28 supply decomposers 30 of feed tube 27 through driven feed tube 27 and elasticity.Also can use feed roller to replacing feed tube 27 and feeder channel 28.The decomposer 30 that is used for rove Y comprises can atwirl decomposition roller 31, and said decomposition roller disposes tooth, brad or the analog of protrusion on its outer circumference surface.Decompose roller 31 and be arranged in the housing 33, said housing is served as reasons and decompose the filament F deliver path that roller decomposites from rove Y.Filament F arrives friction-type spinning apparatus 40 through the fibre guide channel 34 with outlet 35.
According to illustrated embodiment, friction-type spinning apparatus 40 constitutes friction-type spinning cylinder 41, and said friction-type spinning cylinder links to each other with negative pressure source 61.41 acting negative pressure-pumping filament F pass through fibre guide channel 34 to the sleeve of friction-type spinning cylinder 41 through friction-type spinning cylinder.There, but be wound into the yarn T of stable feed by filament, said yarn is transported to fanging noz(zle) 70 by discharge roller to 29, and continues transported to knitting needle 24, and said knitting needle is the knitting needle fabric thus.
When rove Y being resolved into filament F, from fiber F, isolate proportion usually greater than dirt particulate D and the analog of filament F, and discharge through being arranged on the dirt passing aways 36 that decompose below the roller 31 through atwirl decomposition roller 31.For this reason, the other end of dirt passing away 36 links to each other with negative pressure source 60, so that produce enough suction streams.In order to prevent that this suction streams from also carrying secretly by decomposing the filament F that roller 31 produces, dirt passing away 36 for example can be closed through impeller 37 or similar device, and therefore can with decompose roller 31 and separate around the housing 33 and the fibre guide channel 34 of this decomposition roller.
Fig. 3 and 4 illustrates two sectional views of friction-type spinning cylinder 41.This friction-type spinning cylinder has the rotatable sleeve 42 of perforation of disposing 43.Coaxial static guide cylinder 44 is arranged in the sleeve 42 with little spacing, and said guide cylinder has the guide slit 45 of in axial direction extending in its shell surface, and links to each other with negative pressure source.The negative pressure-pumping filament that in guide cylinder 44, exists passes through fibre guide channel to the surface of perforation and sleeve 42 rotation.Fiber remains there regularly, and is rotated in the fringe region of the guide slit in static guide cylinder 44 45, but and is wound into the yarn of stable feed.The yarn that produces is right along the edge arrival discharge roller of guide slit 45, and sends into knitting needle through fanging noz(zle).Extend obliquely through the axis of guide slit 45, and on its shell surface, be " spiral " extension, but help the formation of the yarn of stable feed, and it is right to help that the yarn that forms is continued transported to discharge roller with respect to guide cylinder 44.But guide slit also can be accurately directed vertically.
Static guide cylinder also can have two or more guide slit.So possible is, produces plurality of yarns simultaneously by friction-type spinning cylinder only.
In Fig. 3 and 4, but set forth the generation of the yarn of stable feed with the example of single friction-type spinning cylinder 41.But another embodiment of the invention deformation program as shown in fig. 5 also can have a friction-type spinning cylinder 41, and said friction-type spinning cylinder cooperates with a supporting cylinder 50 with identical direction rotation.Friction-type spinning cylinder 41 forms wedge-shaped crevice 51 with supporting cylinder 50, but in said wedge-shaped crevice, produces the yarn T of stable feed.Guide slit 45 in the shell surface of the static guide cylinder 44 that is connected with negative pressure source is towards wedge-shaped crevice 51.Second friction-type spinning cylinder also can be set replace supporting cylinder.So, the guide slit of the friction-type of two cooperations spinning cylinder is too towards the wedge-shaped crevice that is formed by two friction-type spinning cylinders.
Example with friction-type spinning cylinder is set forth the friction-type spinning apparatus, but said friction-type spinning cylinder is individually or to be wound into filament on the yarn of stable feed with another friction-type spinning cylinder combination or with the mode of supporting cylinder combination.In the another embodiment of the invention deformation program; For example can enough atwirl bored rolls or like replace friction-type spinning cylinder; Filament is blown in the said bored roll; Collect filament through the centrifugal action on interior cylinder periphery, and under the situation that yarn forms, extract out from the center.In the another embodiment of the invention deformation program, the friction-type spinning apparatus also can constitute the friction-type spinning dish of perforation, and the reverse rollers of said friction-type spinning dish and taper interacts.For example oneself knows this friction-type spinning apparatus from GB-1 231 198.The present invention sets forth with the example of circular knitting machine.Self-evident, flatbed knitting machine also can have decomposer and friction-type spinning apparatus.
Fig. 6 illustrates the circular knitting machine that is provided with Reference numeral 21 generally, and said circular knitting machine is provided with storage line apparatus and thread supplying device 100.This storage line apparatus and thread supplying device 100 are also known with term " yarn feeder " in the prior art, so use two titles below simultaneously.Identical parts have and Reference numeral identical in Fig. 2 in Fig. 6.Knitting machine for example also is a circular knitting machine, and said circular knitting machine comprises a plurality of knitting needles 24, and said knitting needle is arranged on the syringe 23 movably.Knitting machine 21 constitutes and is used to process rove Y, and for this purpose, has rove preparation facilities 26.The rove preparation facilities comprises decomposer 30 and the friction-type spinning apparatus 40 that is connected with decomposer 30 respectively.
