Description
Technical field
The present invention relates to a kind of drafting unit that is used for described knitting machine.
Background technology
In the past, multiple method of directly weaving cotton cloth from staple fibre or rove manufacturing needles is proposed.The knitted cloth that one roughly non-twist fiber sliver and the fibrage that approximately is arranged in parallel are got up is very soft, and wear as snug as a bug in a rug.And, because interstage---the formation of yarn of tradition spinning is wound up into it on bobbin and may repeats and reels---be omitted, producing this knitted cloth can be very economical.This non-twist fiber sliver has vertical elastic force to a certain degree simultaneously, and the therefore easier direction that props up the yarn of guide needle loom changes and this yarn can often not disconnect.
For example, document US-A-3,877,254 propose staple fibre is sent on the pin of knitting machine.In this case be that example is as the basis of describing with the tubular knitting machine.This staple fibre is arranged in a circle by hairbrush, is picked by the wheel with hook, and combing is opened, and sends the tubular knitting machine of staple fibre being made knitted cloth again to.Intertwined point in this grid makes knitted cloth have necessary strength.The boost line that yarn also is described simultaneously also can be entered by braiding.
WO 2004/079068 has proposed a kind of tubular knitting machine, and its knitting zone is replaced coming for the yarn material from the refining yarn of the bobbin drawing-off that is assigned to each knitting zone by the fiber sliver of drawing-off in drawing frame before.This drawing frame has three or more cylinders, and it has two aprons and the outlet pressure roller is right, promptly as the ring ingot formula spinning frame that is used to spin of the prior art.The drawing-off from bar tube or flyer bobbin of this rove is come out, and is provided to it is drawing in the drawing frame of predetermined extent.The fiber sliver of this drawing-off can directly offer and be positioned at the knitting needle of this outlet pressure roller to knitting zone afterwards.This configuration is used in particular for having the very tubular knitting machine of the syringe of minor diameter, for example can process long fiber on it.Have larger sized syringe for large-scale tubular knitting machine, for example, 48 or 96 knitting zone can be set, its proposition is incorporated in a twisting device between this drawing frame and this knitting zone.For example, this twisting device comprises pneumatically-operated swirl nozzle, wherein false twisting is offered the fiber sliver of this drawing.So the interim yarn that forms has enough intensity to be transmitted distance far away slightly.This false twisting is unclamped in knitting zone once more, so those fibers are roughly parallel to each other when merging the formation knitted cloth by this knitting needle.
Because the space, for example, this drawing frame is distributed as three groups of circumference that are centered around the syringe of this tubular knitting machine.Every group of drawing frame comprises a plurality of common drivings that are positioned at the drawing frame of same line and are suitable for the driven unit of this drawing frame.The drawing frame assembly of this driving comprises at least one continuous cylinder.For fear of the excessive rapid variation of passing through direction of this fiber between the relevant knitting zone of this group drawing frame with it, start knitting zone at the syringe place and replace so-called dead zone or dead band, this tubular knitting machine does not have knitting zone or should not participate in braiding in the zone herein.Like this, make on the large-scale tubular knitting machine that forms in a known manner, it is available having only only about half of knitting zone.In this relation, even be interpreted as in WO 2004/079068, can take directly to weave rove according to advantage economically, this situation is not most important.Even propose, another kind of mode, the size of this syringe can enlarge, so the circumference of syringe can be provided with a plurality of available knitting zone.
In fact, when the processing fiber sliver in drawing frame during drawing-off, on the large-scale tubular knitting machine only some knitting zone be available, showed that this kind is dark is happy to critical defect on the operation technique for the people.The size that increases this syringe is the room for manoeuvre of technical approach, and because reasons in structure and shortage space, it under any circumstance all is impossible making it.In addition, the assembling drawing frame be one group mean the maintenance they be very difficult.

The specific embodiment
For clearer, identical in the accompanying drawings reference number is represented identical assembly.
Figure 1 shows that the significant components sketch plan of tubular knitting machine, by label 1 expression, it directly makes knitted cloth from rove usually.This tubular knitting machine 1 has syringe 2, and 48 or 96 knitting needles 3, particularly latch needle for example are set on this syringe versatilely.This knitting needle 3 directly processing is placed on the bobbin of tubular knitting machine from the drawing frame sliver of bar tube 5 or from the rove that the slubbing yarn of flyer bobbin is provided.This rove L is drafted and by directly or offer knitting needle 3 by middle twisting device 4 fiber sliver is made knitted cloth in drafting unit 6, and this twisting device makes the fiber sliver of the drawing-off of making from rove L have false twisting.The drafting unit that schematically shows in Fig. 1 is at Fig. 1 three cylindrical body drawing frame particularly, and it includes the mouth pressure roller to 7, by two aprons 8 of apron roller guiding and outlet pressure roller to 9.Drawing frame this or same type generally is used to encircle ingot formula spinning frame.The direction of transfer of the direction of transfer of this rove L or the fiber sliver that produced by this rove is represented with arrow T in Fig. 1.
Shown in Fig. 2 to 5, this whole drafting unit 6 is positioned on the base 60.Each roller is to having upward pressure roller 71,81,91 and following cylinder 72,82,92 respectively.This inlet pressure roller is to 7, be used for the apron roller of two aprons 8 and this outlet pressure roller to 9 following cylinder 72,82 and 92 be installed at one end be connected in base 60 and from base freely give prominence to spool on.This inlet pressure roller 71 and another apron roller 81 are installed on the assembled disc 78 separately by its bearing, and it is connected on the base 60 by elasticity folder 75.This elasticity folder 75 is at the spring bearing 79 outstanding from this base 60 and be located between the thrust point 77 on this assembled disc and extend, and this elasticity folder 75 is by being installed in rotation on clamping cam 76 tensions on the base 60.Like this, this upper inlet pressure roll 71 and upper leather ring roller 81 oppressed this lower inlet pressure cylinder 72 and following apron cylinders 82 that prop up respectively.This tension force can be adjusted by clamping cam 76.This upper outlet pressure roll 91 is installed on the support 96 that can move freely with respect to this base 60.This support 96 is strained by leaf spring 93, and the one end is fixed on the assembling projection 95 of this base 60.91 of this upper outlet pressure rolls are positioned at this support 96, and prestressing force that can be by overcoming leaf spring under export cylinder 92 and promote these outlet pressure rollers 91 and be easy to pull down.
This time cylinder 72,82,92 is driven by electro- motor 62,63, and described electro-motor is fixed on the base 60 and in the mode adjacent with following cylinder equally to be given prominence to from base.This electro- motor 62,63 is preferably the asynchronous electric motor by the frequency converter operation.
Configuration according to the present invention is fundamentally different than three cylindrical body or the polycylinder drawing frame of learning from ring ingot formula spinning frame.The pressure roll of the drawing frame there normally is arranged on common axle in couples with relevant following cylinder and goes up and be assigned to two adjacent spinning districts, yet the present invention proposes autonomous drafting unit 6 fully, its drafting component at one end is fixed in base 60 in the mode of overarm arm.Prop up continuous following cylindrical known drawing frame with the upper outlet pressure roll by spring pressure and compare, it is right that each drafting unit has its oneself outlet pressure roller.Therefore the configuration of adjacent drafting unit is no longer done the rectilinear direction extension with cylinder under the continuous linearity.Be that each drafting unit can be independent of adjacent drafting unit autonomous operation on the contrary.Especially for the independent unit of tubular knitting machine, preferably be adjacent the angled setting in unit.Make all knitting zone of tubular knitting machine can both be supplied to rove like this through drawing-off.
In Fig. 3, can see especially, induction element 61 be positioned at from this inlet pressure roller to 7 to the transfer path of the rove of this pair apron 8.Guarantee when the short fiber rove that particularly all fibres is sent to next drafting component, by two aprons 8 of apron roller 81,82 guiding.For rove or the slubbing yarn introduced, thread guide 10 is arranged at the inlet of this drafting unit 6.It has comprised at the tapered passage 11 of the direction of transfer of this rove.This inlet roller to 7 and the upward pressure roller 71,81 of apron roller of supporting this pair apron 8 by means of tie unit 75,76,77,79 by the spring force compressing to prop up relevant cylinder 72,82 down.This upper outlet pressure roll 91 props up this time outlet cylinder 92 by leaf spring 93 compressings that are fixed on the base 60.
This time cylinder 72,82,92 is driven by electro- motor 62,63, and described electro-motor is connected on the base 60 and is freely outstanding from base.This electro- motor 62,63 is preferably the asynchronous electric motor by the frequency converter operation.The actual actuator of this time cylinder 72,82,92 is positioned at the rear of base 60 and is protected in order to avoid contaminated by lid 64 (Fig. 3).The driving of this time cylinder 72,82,92 shows in greater detail in Fig. 4.For this purpose, the aixs cylinder of this electro- motor 62,63 goes out to pass base 60 and carries driving pinion 65,66.The carrying axle of cylinder 72,82,92 down is equipped with driven wheel 74,84 at the rear portion of base 60,94.Odontoid belt 67,68 will descend cylindrical driven wheel 74,84,94 to be connected with the driving pinion 65,66 of electro-motor.The inlet pressure roller drives by same driving electro-motor 62 at this with the following apron cylinder 82 that is used for two aprons 87 following cylinder 72.The different circumferential speed of the following cylinder 72,82 of two preliminary draw zones that are used to be defined for the slubbing yarn can produce by the different-diameter of driving wheel 74,84.Cylindrical diameter is selected like this under this, makes the size of this preliminary drawing-off be approximately 1.2 or 1.4.The outlet pressure roller drives by electro-motor 63 9 following outlet cylinder 92, and its peripheral speed is obviously greater than other two following cylinders.Friction speed between two aprons 8 and outlet pressure roller 9 has determined that the drawing-off of this rove and its drawing-off coefficient are between 25 to 50.The fiber sliver that is drawing to predetermined extent is output 9 the clamping line that transports at the outlet pressure roller, and or can be provided directly to the pin that is positioned at syringe, perhaps can be fed into the twisting device that produces false twisting.
Figure 5 shows that according to the present invention from the different drafting unit 6 of introducing the rove angle.For clearer, the assembly of demonstration has as reference number identical among Fig. 2 to 4.Can see that in Fig. 5 this drafting unit 6 constitutes and is used for two rove or slubbing yarns that transmit side by side of drawing-off simultaneously.For this purpose, this thread guide 10 is provided with two passages side by side 11 that are used to introduce rove.These two passages all are tapered to the outlet pressure roller to 7 on to 9 carriage direction from the inlet pressure roller at rove.Replace having a thread guide 10 of two passages 11, also can be provided with two side by side have separately a passage thread guide.Improvement structure according to the present invention can make this drafting unit be applied on the knitting machine, particularly the exceptionally close tubular knitting machine in space.Two adjacent knitting zone are provided the fiber sliver of drawing-off simultaneously by a common drafting unit 6.Roller that also can be by appropriate size or cylinder down, the passage that the configuration of the respective numbers of thread guide or thread guide have respective numbers is used for the more rove of drafting unit drawing-off simultaneously.
Fig. 6 has shown the another kind of different drafting unit that is used for the so-called drawing frame sliver of drawing-off.The drawing frame sliver is non-twist and need not preliminary draw zone.Therefore this drafting unit does not have independent inlet pressure roller right.Following outlet cylinder is positioned at after two aprons, with reference number 92 expressions.Because the drawing frame sliver is heavier 4 to 6 times than slubbing yarn, so the expection fineness of yarn that this drawing-off need reach is between 100 to 200.The effect of this high strength drawing-off is to make the fiber sliver of this drawing-off expandable non-constant width behind two aprons.Fiber sliver polymerization once more with this expansion has the compressional zone behind this draw zone.Therefore, guide reel 85 is arranged between upper leather ring roller 81 and the upper outlet pressure roll 91.To similar with the configuration of this upper leather ring roller according to the right upper inlet pressure roll of this inlet pressure roller of embodiment among Fig. 2, this guide reel is arranged on the independent assembled disc, and as upper outlet pressure roll 91, its by the spring supporting loading under export on the cylinder 92.This time outlet cylinder 92 has the perforation sheath.In this sheath, has the fixation kit that closely is butted on this jacket inner surface.This assembly has the cavity that is connected in vacuum source and towards the groove of this jacket inner surface, and extend beyond the circumferential distance of this time outlet cylinder 92, this circumferential distance be from this have following outlet cylinder 92 guide reel 85 sting the distance of line to the clamping line of this outlet pressure roller 9.Air sucks by the perforation on the sheath of this time outlet cylinder 92 by means of fixing cannelure thus.Fiber sliver this expansion, drawing-off is pulled once more under the influence of this air flow and is aggregated to together.Under the compressive state of expection, the fiber sliver of this polymerization leaves and is positioned at the drafting unit of this outlet pressure roller to 9 clamping line place.
This example is used for the design that drawing-off goes out the drafting unit 6 of drawing frame sliver and equally also is provided with thread guide.Can have the passage that a drawing frame sliver that is used to introduce is arranged at this this thread guide, or go out as shown in FIG. 7, two passages 11 are used for two fiber slivers that are supplied to drafting unit 6 side by side of drawing-off simultaneously.In this design, this pressure roll and following cylindrical appropriate size, combination configuration or the passage that thread guide has right quantity of the thread guide of right quantity all can be realized the rove that drafting unit many of drawing-offs simultaneously provide.
The common trait that has at the drafting unit 6 shown in all examples is that this base 60 has quick clamping unit 69, and it allows to change very apace drafting unit 6.For example, this quick clamping unit 69 can be provided with cam gear, can unclamp or tighten for 90 ° by rotating cam, so that the locking of this drafting unit can released once more apace or clamping.Like this, be maintained at and minimize the down time of this knitting machine.
The present invention is to be that example illustrates with the drawing frame that is used for tubular knitting machine.Yet flat knitting machine is suitable for using drawing frame as described in the present invention too, so that can utilize the advantage of direct processing rove.
