Drafting system with compression set 8 can comprise 3 couples of roller 5a on the whole, 5b, 5c, and the additional roller 11 that stops, as shown in Figure 1, perhaps can on the downstream of outlet roller of Fig. 1 a of 3 traditional roller drafting devices, another be set, on the outlet side of the constricted zone 9 of this compression set 8, have the additional roller 11 that stops roller 5d to the 5c place.Among Fig. 1, this roller 50 can be the delivery element of perforation, and this delivery element inside is provided with suction element, should the surface be air-locked perhaps.In each situation, two rollers are pressed on the roller 50, and this roller 50 also is used for the drawn fiber structure if desired as guiding piece, and this second roller 11 is designed to rotation and stops roller, so that stop yarn from this spinning apparatus 12 rotation back.Two roller 50a and 11 can be installed on the retaining element 70, and this retaining element 70 can also be as the installing rack or the guiding piece of this compressing member 60.What a charger is arranged between a retaining element 70 and this compressing member 60, in simple scenario a compression spring is set, and evenly presses this compressing member 60 unchangeably to the surface of this this roller 50 so that guarantee.This retaining element 70 can be connected on the loading arm 71 of this drafting system 4 then, and preferably the jockey by the transition position between this loading arm 71 and retaining element 70 carries out.Can see that from Fig. 1 a this roller also is connected on this loading arm 71 top roller of 5c.
In Fig. 1 b and 1e, the embodiment of the spinning machine that illustrates disperses this drafting system, the parts of compression set and spinning apparatus with respect to Fig. 1.The loading arm 71 of similar Fig. 1 a is arranged on the top roller of this roller to 5a and 5b, and an executive component 72a is arranged on the loading arm 71 by joint 73a, and this executive component back also is called first induction element.If this executive component 72a is not connected with this loading arm 71 by joint 73a, promptly be fixed on this loading arm 71, then this executive component also may be spring arm, for example leaf spring.This induction element 72a supports a retaining element 70 by joint 73b, and roller 50a and 11 is fixed on this retaining element 70, and presses against on the delivery element 50.At roller 50a with stop between the roller 11 and this compressing member 60 is set in the mode of having described.This compressing member 60 is connected with support component 75, by spring 72b compressing member 60 is pressed against on the delivery element 50.Spring element 72b is fixed on the executive component 72a.End at the support component 75 that is used for compressing member 60 can be provided with support 70a, and this support 70a comprises this roller 50a that represents with Fig. 1 b and 1e dotted line and stops the axle of roller 11.If there is these supports 70a, compressing member 60 needn't be positioned on this delivery element 50, but can have narrow gap between compressing member 60 and this delivery element 50.This support component 75 is pressed against on the axle of this roller 50a and 11 by this support 70a.Structure arrow 9 directions along Fig. 1 b in Fig. 1 e that the front provides description illustrate.In Fig. 1 e, dot the leaf spring of this spring 72b for being provided with perpendicular to this executive component 72a, this spring 72b is pressed in respectively on support component or the element 75.Be fixed element 70 of roller 50a and 11 axle 74 is fixing.According to Fig. 1 e, on each axle 74, two roller 50a and 11 are set respectively.This compressing member 60 on these support component 75 opposites can also by radial clearance be directed on this delivery element 50.In this situation, this support component 75 directly is fixed on this retaining element 70, spring 72b is removed, and this compressing member 60 is expressed on this delivery element 50 by the device of for example magnetic force, and perhaps spring 72b extends between this support component 75 and compressing member 60.
The aspirator 66 of Fig. 1 b directly stop roller 11 and delivery element 50 near, this aspirator 66 can also cause the negative pressure in the zone between this compressing member 60 and delivery element 50, therefore the region generating of the leader 61 in compressing member 60 negative pressure.Enter into gap between this delivery element 50 and the compressing member 60 thereby help air along side direction, thereby the fiber of this fibre structure 2 is held togather, and does not enter into this gap.In order to guarantee such result, can also provide further air assembly, for example with reference to the description of Fig. 3 b-3e.
In Fig. 1 b and 1e, opposite side at upstream compressing member 59, letter illustrates and is used for beating or traversing gear 80 of this fibre structure 2, be arranged on roller between 5b and delivery element 50 and the corresponding roller 50a according to this compressing member 59 of Fig. 1 b, promptly still be in the dominant draft zone of this drafting system 4.This upstream compressing member 59 can be connected on this retaining element 70 by the retaining element 59a of Fig. 1 e, therefore this retaining element 70 is used for this roller 50a and also is used for compressing member 60, and this compressing member or these compressing members 60 are fixed by this spring 72b respectively if this spring 72b is fixed on this retaining element 70.Therefore, by retaining element 59a and retaining element 70 in axial direction this upstream compressing member 59 be connected on this compressing member 60, thereby when these elements were beated or traversed, the position of upstream compressing member 59 position of this compressing member 60 relatively was held.Driver or retainer 84 can be arranged on also that this retaining element 59a or retaining element 70 and this beat or traversing gear 80 between, and be connected, therefore the axially-movable that is used for this induction element 82 of this fibre structure 2 along double-head arrow 80 directions of Fig. 1 e also is passed to upstream compressing member 59 and compressing member 60 and roller 50a and 11, shown in Fig. 1 e.Therefore fibre structure 2 is not offset by these elements in unallowed mode when passing this drafting system 4 and compression unit 8 operations, and by described these elements, fiber moves in this drawing-off and constricted zone.If this upstream compressing member 59 moves facing to this compressing member 60 along the axial direction of delivery element 50, this fibre structure 2 is positioned on the side of leader 61, therefore can amplify this compression.
In Fig. 1 c, the outlet profile of this compressing member can make roller 50a and 11 settings close to each other, and the side towards these rollers of this compressing member 60 has the radian of roller 50a and 11.This compressing member 60 can be directly connected on this loading arm 71 by induction element 72b shown in Fig. 1 d or on the retaining element 71a like that, and this induction element 72b can be spring, this induction element 72b can also be directly connected to the retaining element 70 that is used for two roller 50a and 11 shown in the dotted line of Fig. 1 d, so that with opposite shown in Fig. 1 d, the induction element 72b that dotted line is represented only at this retaining element 70 at the upper arm at roller 50a place be used for extending between the first induction element 72a of compressing member 60.This first induction element 72a that is used for this compressing member 60 is arranged on the lower end of this second induction element 72b, and this compressing member 60 can be called the spring loading element.This spring-loaded first induction element 72a can be designed so that this compressing member only is extruded on this delivery element 50, perhaps in the gap between this delivery element 50 and roller 50a, perhaps can only stop that with this roller 11 contacts, thereby the spring force that loads among the induction element 72a at spring is chosen as: only keep less contact force.As shown in Figure 2, this delivery element 50 can also be designed to make belt 5e extend in its surface so that this fibre structure 2 is positioned on this belt 5e in the outlet back of this roller to the gripping gap of 5c.If there is belt 5e, then can omit this roller 50a.In order to keep guiding the element of fibre structure 2 clean, can make cleaner roller 90 and this roller 50a, 5c contacts with 50, wherein only shows at this to stop of roller 11 places.Except above-mentioned, cleaner contacting with the surface of this roller with 92 can be set, wherein only one such illustrate with 92 delivery element 50 places in Fig. 1 d.
Opposite with the embodiment of the drafting system 4 of Fig. 1 c or 1b or 1 and compression set 8, can also delivery element 50 be arranged to away from this actual drafting system shown in Fig. 1 d.In this situation, the roller of Fig. 1 d is that to be arranged in the roller in zone of this drafting system 4 right to 5c, and to the 5c place, the main drawing area of this fibre structure 2 finishes at roller.So-called active drawing-off or passive drawing-off can be carried out between this roller is to the gap between 5c and this delivery element 50 and the roller 50a, roller that perhaps can be on the one hand is to 5c and 50,50a, this delivery element 50 on the other hand and stopping between the gripping gap between the roller 11 carries out, if produced different transporting velocities or peripheral speed with the roller of fibre structure contact.For example, determined gearratio at the driver element place of this delivery element 15, this gearratio makes and keeps the peripheral speed littler or bigger to the peripheral speed of 5c than this roller.For example can also between this roller 50 and 50a and 50 and 11, carry out drawing-off, shown in Fig. 1 d, promptly be compressed by stopping that as rotation the dressing roller 11 of the biasing of roller reaches passively.Shown in Fig. 1 c, at this delivery element 50 and stop on the outlet side of roller 11 induction element 15 ' or 15 " can be set to special hull shape respectively so that the inside position of this yarn of rotation of influence.As Fig. 1, it can also be kept by special biasing element 15 '.
Structure at this roller-compressing member shown in Fig. 2 and other accompanying drawing.Between this roller 50 and this compressing member 60 sides, belt 50b is set, is suitable for this roller and towards this roller.This belt is called apron and is provided with driving mechanism, in the simplest situation, drives by roller 50.Sealing ground guiding belt 50b is not illustrated around the biasing or the rollback point of this roller.As described, this compressing member 60 presses this roller 50 with the dynamics that limits by charger 72, perhaps presses on this belt 50b.But in some cases, this not necessarily, as described later.When not having belt 50b, be located immediately on the surface of this roller 50 from the fibre structure of these drafting system 4 guiding, perhaps on the surface of this belt, be directed.In the zone of this compressing member 60, this fibre structure 2 enters into the zone of the slit 61 of compressing member, and this compressing member has represented to have the funnel in cross section constant or that narrow down.This mechanical compress effect in order to support to be undertaken by the sloped sidewall 61c among Fig. 2 a is provided with some holes in slit 61, these holes are led to this compressing member 60 and are roughly parallel to the axle of this roller 50.In axial hole 62, Fig. 2 shows 3.At Fig. 2 a, 2b, these holes 62 are roughly parallel to the figure plane extension among 2aa and Fig. 3.Compressed air is directed in this compressing member by the outside of these holes from this compressing member, promptly enters into slit 61.Preferably Fig. 2 a and these holes 62 of 3 are obliquely installed with respect to the throughput direction of this fibre structure, shown in the arrow 62 of Fig. 2 a, not only 62 places contact opposed sidewall 61c in the hole so that make fibre structure, but also by obtaining to carry effect along the shunting of throughput direction on this fibre structure 2.Fig. 2 a shows the fibre structure 2 initial central authorities that are positioned at this slit 61 more on the entrance side of this compressing member 2, but in the zone in this hole 62, because leaked-in air, this fibre structure is pressed into the left side wall 61c place of this slit 61 more.Because the inclined trajectory of this sidewall 61c also contacts the fibre structure setting with left side wall.
The arrow of Yan Shening has illustrated in Fig. 2 a from the top down, and compressed air is by from both sides, promptly the hole of the unshowned correspondence by hole on the right side of this compressing member 62 and left side is blowed.In this situation, this mechanical compress effect is replaced by the pneumatic compression effect.
According to Fig. 2 b, the throughput direction that this axial hole 62a can be approximately perpendicular to this fibre structure 2 extends, more at the entrance area of this slit 61, and at the outlet side of this slit, this axial hole 62b tilts to extend with respect to this throughput direction, so that the fiber of shunting this fibre structure 2 from the air of hole 62b applies tension.Therefore this fibre structure stretches in this compressing member 60 when passing slit.
The symmetrical structure of the slit 61 from Fig. 2 a, this slit 61 tilts to extend perhaps asymmetric extension at compressing member 60 places of Fig. 2 b.In this design, the design that is provided with than Fig. 2 a on the mechanical compress effect of this sloped sidewall more is worth.
Except axially extended hole 62 roughly, beyond 62a and the 62b, roughly hole 63 radially can also be arranged in the compressing member 60, so that deflate from the gap between the inboard of roller 50 or belt 50b and this compressing member 60.Like this, this compressing member 60 can contact with the surface of this roller 50 or belt 50b, does not even use charger 72.Therefore therefore, be reduced, avoided single fiber from this fibre structure 2 to snap onto danger in the described gap in the gap between their side of delivery element 6 or roller 50 or belt 50b and this compressing member 60.
In Fig. 2 aa, from the plan view of the structure of top 2a with the aid of pictures, the position toward each other of radial hole 63 and axial hole 62 can be in sight, and the inboard of this compressing member 60 perhaps also can be seen with respect to this roller 50 of the entrance side that enters hole 63 or the position of belt 50b relatively.Can see the deflection extension each other of this hole 62 and 63 from Fig. 2 a, and hole 62 is by the intermediate space between the hole 63.Hole 63 63a along the line are positioned at the both sides of this slit 61, and this line 63a extends along the circumferencial direction of this compressing member or roller 50.
Among Fig. 2 c and the 2d, slit 61a that is shown in broken lines and 61b are arranged in the diverse location place of same compressing member 60.If tendency is made the different yarns of twisting with the fingers to (S, Z twists with the fingers), towards the right side or the position of the slit in left side be very important.The purpose of the design of Fig. 2 c is that the fibre structure that extends is from top to bottom at first contracted in a side pressure, and the opposite side to this compressing member 60 moves then, therefore is compressed from both sides.
In the structure of Fig. 3,, lead to the inside of this slit in the axial surface of compressing member 60 hole 62 that is provided with that tilts along in the plan view of this compressing member 60 of arrow 72 directions of Fig. 2 and roller 50.Suppose because the air that is blowed along the direction of arrow enters into left hole, so fibre structure moves to this right side wall 61c.Make fibre structure partly enter this gap if allow to be used for fibre structure 2 in the surface of this roller 50 and the less clearance between the side of roller of this compressing member 60, air-blast device 35 is preferably disposed on the side of this compressing member 60, be positioned at the opposite of left hole 62, be blown into gap between the surface of the surface of this roller 50 and compressing member 60 from this air-blast device air by side direction, a spot of air that therefore enters into slit prevents that the fiber of fibre structure 2 is stuck in this gap.Roughly extend on the surface of this hatched area S in the right hand portion of the compressing member 60 of Fig. 3 in described gap.This air-flow that the fiber that prevents fibre structure 2 enters in this gap roughly extends along the dotted line 36 of the hatched area in the right hand portion of the compressing member 60 of Fig. 3.
This air-blast device 35 can be designed in such a way that passage 36 is from 62 extensions of the axial hole to compressing member 60 here.The A/F of passage or Cross section Design become to make that air flow ratio each other is what expect.
Among Fig. 3 a, show another overall structure of the described element of perspective representation with letter.This compressing member 60 of radian that adapts to this roller 50 is towards these roller 50 bendings, and passage 61 or slit 61 respectively in the central authorities of described element along the circumferential extension in the surface of this roller 50.
Side direction gets out or otherwise forms hole 62 in compressing member 60, and the circumferencial direction along this roller has an element simultaneously, if this element is a plastic components.
Be connected on second aspirator 40 that arrow 40 letters show near the radial hole 63 of two side surface, this radial hole 63 can improve the position of the compressing member 60 on this roller.
By air-blast device 30, pass through suitable passage 36 compressed-air blows of Fig. 3 to hole 62 from the side of this compressing member 60.This second aspirator 40 can make up with air-blast device 30, make the passage of this second aspirator 40 and the channel connection of this air-blast device 30, thereby in air-blast device, caused swabbing effect in the passage of this second aspirator 40, thereby also caused the swabbing effect in hole 63 with swiftly flowing air.
Notice the following fact according to Fig. 1: this pinch effect can also support by first pumping unit 13 of quilt in the roller inside of this perforation, and this suction element 13 is connected on the aspirator 14.The purpose of this swabbing effect is that fibre structure 2 is kept together, and moves up with delivery element 6 or roller 50 or belt 50b continuously.
If as this delivery element 50 of Fig. 2 is belt 50b, then can use non-moving skew or the inversion element, particularly tubulose that replace roller 50.
This air- blast device 30 or 35 is designed to: can adjust the volume of air of injection, particularly the air that relatively sprays from the side of the compressing member 60 that is positioned at slit 61 opposite sides sprays by the opposite side of hole 62 more air from this compressing member 60.
