Abstract
An apparatus for making a yarn consists of at least one ring spinning mechanism and a drawing mechanism, which precedes the ring spinning mechanism and defines at least one draft path for drawing a fibrous roving and includes two delivery rollers defining a clamping nip for the drawn roving, wherein one of said delivery rollers constitutes behind the clamping nip a guiding surface for deflecting the drawn roving. In order to increase the strength of the yarn, it is proposed that the delivery roller which constitutes the guiding surface for deflecting the roving constitutes at least near the delivery end of the guiding surface a slideway for guiding the roving transversely to its axis as the roving is twisted between the ring spinning mechanism and the drawing mechanism.
Description
Involved in the present invention is a kind of device of producing yarn, form by at least one ring spinning mechanism and a drafter, drafter is before ring spinning mechanism, it has a drawing-off path in order to the drawing-off rove at least, and it includes two delivery rollers as the gripping jaw of drafted rove, and one in the above-mentioned delivery roller has a spigot surface that drafted rove is turned to after gripping jaw.
The intensity of the yarn of being produced by well-known ring spinning mechanism depends primarily on steel traveler by ring spinning mechanism and is added on the twist on the drafted rove, but since in the ring spinning mechanism speed of steel traveler can not resemble requirement increase, like this twist that is added on the yarn just there is a restriction, when particularly if yarn is at full speed exported, in order to attempt to provide the rove of suitable densification, so just must improve the fibre guide of drafted rove, someone advises that (DE-A-1178749) delivery roller in drafter has arrowhead form or rounded trenches, an air draught district is set near above-mentioned groove, like this because the effect of the groove of delivery roller, reach help at air draught district air draught air-flow, fiber can be close to mutually, so the width of rove bar will reduce, but fiber is not close to as described in can not resembling mutually, unless fiber is done the feeding direction motion corresponding to the groove delivery roller, the front end that needed transversal force can only be applied to those fibers has arrived at the groove delivery roller of drafter and also has not been output on the fiber that the gripping jaw between roller clamps, for this reason, it is special because the gripping jaw between delivery roller has increased the width of rove, whole rove only has the little densification of degree, and the gripping jaw between delivery roller is considered to the high draw zone of drafter.
A kind of production yarn equipment is disclosed in US3122794, this equipment is made up of a ring spinning mechanism and a drafter, drafter is before ring spinning mechanism, it has a drawing-off path in order to the drawing-off rove, and have two delivery rollers as the gripping jaw of drafted rove, one of them delivery roller has a spigot surface that drafted rove is turned to after gripping jaw, have guide face to delivery roller dispose the air draught district of on circumference, extending.
But the disclosed device of US3122794 is the boundling fiber efficiently, can not produce and close total yarn.
For this reason, the objective of the invention is to increase spinning speed within the specific limits by driving bobbin and not worrying loss of strength.
The present invention relates to a kind of production yarn device, at least form by a ring spun yarn line mechanism and a drafter, drafter is before ring spinning mechanism, it has a drawing-off path in order to the drawing-off rove at least, and have two delivery rollers as the gripping jaw of drafted rove, one in the above-mentioned delivery roller has a spigot surface that drafted rove is turned to after gripping jaw, the delivery roller with spigot surface disposes the air draught district of extending on circumference; It is characterized in that: in order to retrain drafted rove, between the output of the spigot surface that drafted rove is turned to and the gripping jaw between two delivery rollers in the drafter, dispose a pressurization roller, in order to aspirate drafted rove in the circumferential area that is positioned between jaw and pressurization roller, above the delivery roller spigot surface and near the air draught district and at least one lateral surface in the air draught district of longitudinal extension dispose blowing device, the blowing air-flow flows towards the longitudinal direction that lies across above-mentioned air draught district on above-mentioned spigot surface.
According to the present invention, just can obtain such effect: have that delivery roller that makes the spigot surface that rove turns to, form a ways as far as possible nearby at its spigot surface output, when rove was twisted between ring spinning mechanism and drafter, it is traversing to its axial line that ways is used for guiding rove.
Because have the drafted rove of guiding of that delivery roller formation of spigot surface in the drafter to the traversing ways in its axle center, so the twist that is added to rove by the steel traveler of ring spinning mechanism can reach the zone to spigot surface, be to lean against on the ways motion owing to the twisting of rove like this and be to lie across the axial line of rove and upwards advance that those can continuously produce as the fibre end that bristle is given prominence to inevitably from fibre structure against rove.The result is, outstanding fibre end can be wound onto on the rove, the yarn that has higher-strength like this under given spinning conditions must be produced, and that delivery roller with spigot surface also has other advantage: the direction of motion that is wrapped on that delivery roller is consistent with the outbound course of rove.
Ideal results is can be utilized satisfactorily around the fibre end that rove twines, and this requires to have such one section circumferential length on the circumference of formation ways of delivery roller, thus the above-mentioned ways that is contacted by rove can be twisted as far as rove that.This just means that ways must have the circumferential length of the one section minimum that depends on andfrictional conditions.In order to guarantee to dispose the ways with minimum circumferential without difficulty in design, the delivery roller that spigot surface arranged can be corresponding big on diameter than other delivery roller, and the ratio that requires diameter under most of situation is at least 1.5 to 2.
In order to help the rove twisting of contiguous spigot surface, the invention is characterized in: in order to retrain drafted rove, have between an output that makes the spigot surface that drafted rove turns to and the gripping jaw between two delivery rollers in the drafter and dispose a pressurization roller, in order to hold the drafted rove in the circumferential area that is positioned between jaw and pressurization roller, there is the delivery roller of spigot surface to dispose the air draught district of on circumference, extending, blowing device facing to the delivery roller blowing of disposing the air draught district is configured near the air draught district, and be configured in its at least one vertical lateral surface, blow out air-flow and on above-mentioned spigot surface, flow towards the longitudinal direction that lies across above-mentioned air draught district.Because disposed blowing device, they are configured in and are positioned at the vertical outside, an air draught district that grips between jaw and pressurization roller, the pressurization roller also separated with it before the output of spigot surface, can aim at drafted rove so on spigot surface, lie across the air-flow that drafted rove blows away to the air draught district, rove is adsorbed on the spigot surface by the air draught district, so boundling fiber efficiently just.Because boundling fiber generation not in high draw zone but after this is distinguished, when occurring in the gripping jaw of rove between two delivery rollers, rove can keep the narrow width that obtained, because the fiber in the rove bar of broad has been close to mutually.The pressurization roller retrains rove behind blowing device, it can guarantee to guide rove as needs, like this fiber not boundling can get help significantly, this is because the cross force that is produced by blowing acts on the cause on the rove between two guiding of rove, and these two guiding are constituted by the gripping jaw between two delivery rollers in the drafter and by the guiding jaw between pressurization roller and delivery roller.The guiding jaw of being determined by the pressurization roller is different from the gripping jaw, the former only needs to prevent the guiding force of side direction sideslip, the rove boundling that comes from that guiding jaw like this has the shape of an approximate square cross section, the result is, thereafter the twisting of fiber will become simply, because the fiber that in the rove bar of actual width, does not cross out, and in a leg-of-mutton zone, remove to be close to mutually the rove that forms a circular cross-section.
If dispose two ring spinning mechanisms and have at least two to be a drafter of the drawing-off path composition of rove separately, can obtain the situation of the drafted rove of desirable especially boundling, make that delivery roller of the spigot surface that rove turns to dispose two air draught districts if having one, they are associated with separately rove, and be arranged in and be positioned at the circumferential section that grips between jaw and pressurization roller, define a leg-of-mutton surface roughly between the above-mentioned air draught district, it expands outwardly in the feeding direction, and blowing device is facing to above-mentioned triangular surface blowing.Because blowing device be configured in a triangular surface roughly being positioned at two air draught intervals near, and at feeding direction bifurcated, blowing on each delivery roller will the separated into two parts air-flow, these two strands of air-flows lie across the diffluence in the opposite direction of drafted rove, the result is: since two drawing-off paths be close to arranged side by side, a little sideshake is only arranged between rove, and rove has just been increased by the gap between them after blowing open.Because the air-flow that rove is aspirated by the air draught district at that time is adsorbed on the delivery roller, fiber can be very effectively by boundling like this.Because drafted rove laterally is open, so the interval that the interval between rove can be adjusted to ring spinning mechanism is complementary.
Because rove has the cross section that the cross section of the yarn that will produce is complementary after by boundling, increased yarn strength.Rove can be twisted easily by the steel traveler of subsequently ring spinning mechanism, and the result is: carded is prepared rove make thin rove and offer this drafter, just can produce thin relatively yarn.If, producing thin relatively yarn not as described by boundling, drafted thin rove can only come from combing preparation rove.

Fig. 5 is a side view, and some areas are cut open, has shown the device of Fig. 4.
Fig. 6 is the top view that shows that device.
Fig. 1 to Fig. 3 specifies with method for example.This device is mainly by forming for the drafter 1 of drawing-off rove 2 and ring spinning mechanism 3.Ring spinning mechanism designs routinely, and includes ring rail 4 and bobbin 8, is equipped with rings 5 on the ring rail, and steel traveler 6, steel traveler are installed on the rings 5 also removable.Bobbin is by wharve 7 transmissions that are contained on the spindle.
Be positioned at 13 of gripping jaw 15 and pressurization rollers, delivery roller 10 disposes an air draught district 16 and removes to aspirate drafted rove 2.For this purpose, delivery roller 10 has a suitable aspiration channel 17.Two blowing devices 18, they are configured in vertical separately lateral surface in air draught district 16, and extend on the circumferencial direction of delivery roller 10 in the air draught district.Each above-mentioned blowing device 18 has a flat mouthful of nozzle, it and air draught district 16 are similar to abreast extends, and blow out air-flow towards air draught district 16, blowing is flowed out at 19 places of spigot surface 11, towards lying across air draught district 16 direction diffluence longitudinally, as shown in Figure 3, because suction by near the air draught air-flow 20 the air draught district 16, rove is attracted on the delivery roller 10, and be imported into and grip jaw 15 and guiding jaw 14, the air-flow that blows out at 19 places is the collection of filaments, have so as shown shape of cross section like that and obviously wide rove can convert cross section to as 21 shapes, this cross section more approaches the cross section of the yarn that will produce.Because this reason, the fiber of wide rove bar does not need to move mutually in a leg-of-mutton zone to be close to when fiber is twisted in guiding jaw 14 backs, and present the yarn of circular cross section, and will improve so the row of fiber is straightforward, the intensity of yarn will increase.
Fig. 4 to Fig. 6 specifies with method for example.This example is made up of 4 ring spinning mechanisms 3 and related therewith two drafters 1, and two drawing-off paths of the promising rove 2 separately of each drafter are formed.Each root rove is fed in the ring spinning mechanism 3.As the unwinding from the bobbin 22 separately of the above-mentioned rove 2 of thin rove, and be fed in couples in two drafters 1, along drafted in a biserial draw zone near drawing-off path arranged side by side.
See to such an extent that know better from Fig. 4 and Fig. 6, a public delivery roller 10 is associated with two drafters, and co-ordination, and its diameter specific output roller 9 is much bigger.On delivery roller 9 and 10 s' gripping jaw 15 back delivery rollers 10, has a spigot surface 11 that drafted rove 2 is turned to.In order to aspirate rove 2, delivery roller 10 is positioned at and disposes a pair of air draught district 16 that becomes fork-shaped on the circumferential surface of 13 of each delivery roller 9 and every pair pressurization rollers, the pressurization roller is after feeding is positioned at two delivery rollers on the direction, and air draught is that the aspiration channel 17 by delivery roller 10 acts on the air draught district.Clearly be positioned at the 16 middle surfaces 23 of leaving a general triangular with each drafter 1 connected two air draught districts, it expands outwardly in the feeding direction, and a blowing device is arranged towards 23 blowings of above-mentioned triangular surface.
Between the rove 2 that after the gripping jaw 15 of 10 of the delivery roller 9 of each drafter 1 and public delivery rollers, occurs a little sideshake is arranged, this because the drawing-off path be close to arranged side by side.The air-flow that blows out from blowing device 18 blows rove 2 open, and the gap between rove has just been strengthened like this.Consequently: above-mentioned rove bar is further by boundling, and is special because pressurization roller 13 has limited the lateral displacement of rove effectively.
Because the collaborative work in blowing device 18 and air draught district 16, rove is a boundling in couples, when fiber is twisted, need not like this in leg-of-mutton zone fiber lumped together and make yarn present circular cross section, otherwise originally need during the rove twisting of the broad that comes out from the high draw zone of drafter 1.In addition, crossed pressurization roller 13 and made the outstanding rove fiber roll effect on the every rove having to the rove guiding on the delivery roller 10, this is can be as far as the guiding jaw 14 between pressurization roller 13 and delivery roller 10 because of the twist that is added to rove by ring spinning mechanism 3, be winding on the rove 2 of rotation in the outstanding end of fiber on the surface of delivery roller 10 like this, before the point 12 of pressurization roller when rove 2 leaves delivery roller 10, and leave with it at interval.
