Description
Technical field
The present invention relates to a kind of knitting machine that is used to process rove as described in the preamble according to claim 1.The invention still further relates to the independently method by rove manufacturing needles fabric as described in the preamble of claim to a method of a kind of basis.
Background technology
Propose in a different manner in the past, knitwear are directly made by staple fibre or rove.The knitting processing of the non-rotary fiber sliver basically of the fiber by having approximate parallel orientation, the knitwear of making have very " soft hand feeling ", and have very high wearing comfortableness.In addition, these knitwear can be made 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 illustrates with the example 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 described 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 by knitting together.
A kind of circular knitting machine has been described in WO 2004/079068, the knitting point that rove is supplied with described circular knitting machine replaces the finished product yarn of extracting out with each knitting spot correlation connection from yarn tube, described 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 described roller is determined the degree that stretches to this tensioning system by the roller of feed and discharging, and therefore determines 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 by false-twisting device.So the temporary transient yarn that 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 enter in the knitwear of being made by knitting needle with the position that is parallel to each other basically.
What also proposed is that the rove that is stretched guides by 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, may occur so polluting the fiber sliver that described 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 being subjected to 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 strengthens in false-twisting device, this can cause the unacceptable hole in the knitwear of being made by knitting needle.
Summary of the invention
The objective of the invention is to, a kind of knitting machine that is used to process rove of following improvement reduces 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, and described knitting machine has in the feature described in the characteristic of claim 1.According to the present invention, this purpose also is achieved by a kind of method that is used for being made by rove knitwear, and described method has listed method step in the characteristic of claim to a method independently.Improvement project of the present invention and/or favourable embodiment deformation program are the device claim of corresponding subordinate or the theme of claim to a method.
The present invention proposes a kind of knitting machine that is used to process rove, and described knitting machine has the knitting point of some, supplies with in the rove preparation facilities rove through respective handling to the pin of described knitting point respectively, so that produce knitwear thus.The rove preparation facilities is positioned at before the knitting point, and described rove preparation facilities has the friction-type spinning apparatus of yarn of stablized conveying that is used for that rove resolved into filamentary decomposer and is used for filament is processed into the fineness of expectation respectively.
Replace that knitting machine known in the prior art is employed to have input roller with the rotation of different peripheral speed to the drafter right with outlet roller, the present invention proposes, be arranged on knitting some rove preparation facilities before, described 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 the yarn of the pollution of rove and enhancing.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 by feed roller to or the feed tube carry out, described 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 described housing has feed orifice and is used for filament is flowed to the fibre guide channel of 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 by 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, described cylinder can be rotatably set in little spacing fibre guide channel outlet below.Friction-type spinning cylinder is known in prior art, and for example is used to make coarse yarn, and described coarse yarn is used to make Floor wiper cloth or thick ornament materials.The yarn of making by friction-type spinning cylinder has sufficiently high conveying stability, so that also can be transported to the pin of knitting machine from friction-type spinning cylinder on long distance under situation about not breaking.
Yarn by unique friction-type spinning cylinder manufacturing can stablizing conveying 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 described wedge-shaped crevice is with the extension below the outlet of fibre guide channel of little spacing.Beginning can be stablized the formation of the yarn of conveying 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 the rotatable sleeve and the static guide cylinder that is arranged in this sleeve through punching.Be provided with at least one guide slit of extending along the longitudinal direction of friction-type spinning cylinder on the shell surface of static guide cylinder, affiliated guide slit can be connected on the negative pressure source.The filament of carrying on sleeve remains on by negative pressure in the zone of longitudinal edge of guide slit, and is wound into the yarn that can stablize conveying by 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 mutually.
Extend obliquely by the longitudinal axis of guide slit, help the conveying of the yarn that produces along guide slit with respect to friction-type spinning cylinder.
The yarn of the stablized conveying that produces preferably by discharge roller to carrying, in the prolongation of described 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 described 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.
The method according to this invention is to produce knitwear by knitting machine by rove, wherein supply with in the rove preparation facilities rove to the pin of knitting point respectively through respective handling, so that produce knitwear thus, it is characterized in that, rove is resolved into filament, and be wound into the yarn of stablized conveying of the fineness of expectation by the friction-type spinning apparatus.Decomposer and friction-type spinning apparatus that use has obviously less fault rate and needs less maintenance to expend replace tensioning system.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 yarn can be delivered to knitting needle from the friction-type spinning apparatus.The yarn of producing is to have stranded real yarn, described stranded can the confirmation on knitting needle He in the knitwear.Therefore broken string almost no longer appears.
For example the rove of extracting out by the flyer spindle spool suitably by feed roller to or supply with the interactional feed cylinder of spring-loaded feeder channel and to decompose roller, described 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 described 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 by 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 by the dirt passing away that is connected with negative pressure source.Dirt passage separates by 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 entering fiber channel.
Filament is suitable to be wound into the stable yarn of carrying by means of friction-type spinning cylinder.This class friction-type spinning cylinder is known 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 through perforation, described 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 perforation, and is wound into the yarn that can stablize conveying 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, carries out yarn then and form in described wedge-shaped crevice.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.By 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 produces in the friction-type spinning apparatus 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 described 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 described 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.For weaving/spinning process, the driving decoupling fully each other of knitting machine and decomposer and friction-type spinning apparatus.Therefore, under the situation of static knitting machine, at first be woven into the yarn that to stablize conveying 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 by 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.
