The fiber strand is transferred through the condensation zone by an air permeable conveyer belt guided on a slide surface of a suction channel. The suction slit is arranged in the slide surface and the slit essentially extends towards the moving direction of the conveyer belt. The suction slit is equipped with a wide ranging region having a wider region than that of an intermediate region installed in the upper stream in the end region thereof.
Description
Technical field
The present invention relates to a kind of device at a collecting one ribbon on spinning machine, it has a set district that is placed in the front roller of a drafting system to the downstream, the ventilative conveyer belt of a conveying fibre rod by set district arranged, have one be placed in draw zone, make the suction channel that conveyer belt leads and have one to be placed in the suction slot that extends by the conveyer belt traffic direction in the sliding surface, substantially on sliding surface.
Background technology
When one the drawn fiber bar directly the downstream is obtained spinning twisting at the front roller of drafting system, then can produce so-called spinning triangle at the right jaw line of front roller.Therefore making, the drawn fiber bar leaves drafting system and twists into a yarn than minor diameter with the width of stipulating.The spinning triangle contains the inappropriate edge fiber of twisted yarn that is clamped into, and the latter seldom maybe can not help the brute force of resultant yarn., tend in recent years in a so-called set of the draw zone arranged downstream of drafting system district, this set district is that output jaw line with outlet side is as the border for this reason.Spun yarn obtains twisting in this jaw line downstream.Fiber is in set district's boundling or set, and ribbon is thin to no longer producing fearful spinning triangle when leaving the jaw line like this.Resultant yarn is comparatively even, and is powerful big, less filoplume.
The prior art of above-mentioned this device can be learnt from DE 199 03 113 A1.Illustrate in the document, at fixing sliding surface with operate between the bottom side of conveyer belt on the sliding surface and can gather flyings and dust, the generation of these trifle in the world things for example is because the particularly very short fiber of the ribbon single fiber that should gather enters into the inside with its front end aperture by conveyer belt in the suction slot zone.State also in the document that the danger that fiber gathers mainly occurs in the terminal area of suction slot.
Summary of the invention
Task of the present invention is, prevents that as far as possible terminal at suction slot from producing this fiber and gathering.
The solution of this task in above-mentioned this device is that promptly suction slot has a district of widening of being wider than its front zone line in the terminal area.
According to feature of the present invention, obtain a bigger air mass flow in the suction slot terminal area, the danger that fiber gathers takes place thereby reduce.In addition, widen the gap width that the suction slot termination environment enlarges,, reduced at this regional fiber and hung the danger of staying merely from mechanical viewpoint owing to above-mentioned.Coming below the conveyer belt from the side or pass the some fibre of eyelet, mainly is that staple fibre can be got rid of as waste material through suction channel.
The width of widening is between 2.5 and 3.5 millimeters, and then the suction slot of 1.5 mm wides is shown as best.
Widening of suction slot terminal area can be implemented in both sides, and for the production reason, certain symmetry is favourable.Design by rectangle if widen basically, and good rounding is arranged, the length of then preferably widening is a bit larger tham its width.Also can select to add width basically by circular design, its advantage is that fiber loses and can hang this little angular radius of being detained.
Widen not necessarily and will be arranged on the real suction slot.In technical scheme of the present invention, can separate by a partition and real suction slot specifically widening the district.This partition should be very narrow, is no more than 1.5 to 2 millimeters.
The front is mentioned, should prevent that spinning twisting from rotating back into the set district.Therefore a jaw line generally is set in the suction slot terminal area, this jaw line can cause the certain wearing and tearing on the aspirating air pipe naturally.For this reason, widening the district is provided with reinforcement and then has advantage.This reinforcement should be a removable at any time consumable accessory.
Other advantage of the present invention and feature can from following several have the explanation of illustrated example learn.
Description of drawings
A device partial cross section side view of Fig. 1 collecting one ribbon;
Fig. 2 is according to the actual set district view of arrow II direction among Fig. 1;
Fig. 3 to Fig. 6 is according to the enlarged drawing of several enforcement leading cases of suction slot of the present invention.
The specific embodiment
Fig. 1 and Fig. 2 only represent a spinning machine, the particularly collecting one of the ring spinner drawing-off zone of one of the ribbon 2 of spinning twisting device 1 also.The downstream that this device 1 is located immediately at drafting system 3, this drafting system only illustrate front roller to 4 and a pair of apron roller 5 that is placed in the front along throughput direction A.The apron roller is to apron 6 and upper leather ring 7 under 5 guiding.Front roller comprises a driven preceding bottom roll 8 and the preceding pressure roller 9 that elasticity is pressurizeed to 4.Front roller forms the preceding jaw line 10 of the draw zone terminal of drafting system 3 to 4 qualifications.
Under known mode, an one ribbon or rove 11 are drawing to desired number by throughput direction A in drafting system 3.Jaw line 10 and produce a drawing-off ribbon 2 of no twist still before this drawing-off terminates in from this jaw line.In order to prevent to produce known and imperfect spinning triangle in when twisting, ribbon 2 is directly gathered in set district 12, downstreams of preceding jaw line 10.
Be positioned at a suction slot 16 of sliding surface 15, it makes tiltably-mounted a little towards the traffic direction B of conveyer belt 13, and it has had a fiber guide limit 17 with regard to the ribbon 2 that should gather like this.Along these fiber guide limit 17 operations, at this moment be in fiber in the ribbon 2 transverse to the traffic direction B boundling or the set of conveyer belt 13 during ribbon 2 set, some twisted ribbon slightly 2 this moments.
Set district 12 is subjected to one at outlet side and grips defining of roller 19, grips roller ribbon 2 and conveyer belt 13 are pressed to sliding surface 15, and limit an output jaw line 20, and this jaw line plays the resistance twist effect for spinning twisting to be applied.Grip roller 19 and drive conveyer belt 13, and itself is from front roller 9 transmissions by a drive 21.
The yarn 22 that forms is to obtain its spinning twist in output jaw line 20 downstreams, and this moment, yarn was to enter into a twister of not representing on the figure by outbound course C, for example a ring ingot.Export jaw line 20 and play resistance twist, thereby spin to twist no longer to extend to return to affact and gather in the district 12 for this spinning twisting.
See that from Fig. 2 the initiation region 24 of suction slot 16 is provided with short widening in its this side towards fiber guide limit 17 and distinguishes 25.It is the ribbons 2 that slightly traverse transverse to throughput direction A by known manner in order to make that in the initiation region 24 of suction slot 16 this widened district 25, no matter its transverse movement also can reliably keep ribbon 2 to arrive fiber guide limit 17 all the time.
Because conveyer belt 13 is breathed freely, single fiber mainly is that staple fibre can accumulate in production run voluntarily, is not attached in the yarn 22 of production.These loss fibers can from avris enter conveyer belt 13 below and enter the centre of conveyer belt 13 and sliding surface 15, staple fibre also may be partly enters from the pore of conveyer belt 13, is not sucked pipeline 14 and siphons away and hang and stay on the conveyer belt 13.According to experience, flyings are built up and are occurred in the terminal area 26 of suction slot 16.
In order to prevent that this flyings from gathering, suction slot 16 is set to one and widens district 27 in its terminal area 26, and it is wider than the zone line 28 of suction slot 16.Air mass flow increases in the terminal area 26 of suction slot 16, causes no longer to produce flyings in this place's reality and gather.The termination environment of widening 26 stops extension of loss fiber to stay by its size, makes the loss fiber can enter in the suction channel 14 by different way with no damage and arrives aspirator.
A technical scheme according to suction slot 16 of the present invention has been done bigger amplification at Fig. 3.See from Fig. 3, fiber guide limit 17, the sintering 24 of suction slot 16 and the initial district 25 of widening thereof, zone line 28 and terminal area 26 are provided with approximate rectangular widening here and distinguish 327.Widen district 327 and extend, have and be a bit larger tham a length of widening district's 327 width to the both sides of suction slot 16.
According to the embodiment of Fig. 4, the termination environment 26 of suction slot 16 is provided with one and widens district 427, and it is designed to circle.Its very big advantage is not exist in the widened section to make fiber might hang the minor radius of staying.
According to the technical scheme of Fig. 5, widen district 527 and also be designed to circle, but suction slot 516 itself is to be separated by a narrow partition 529.Consider that from the production technology viewpoint this structure is favourable.
As shown in Figure 6, widening district 627 can be placed in the reinforcing member 630 fully.It shows, what reinforcing member 630 can comprise representative feature of the present invention that all are different widens district's modification.Because output jaw line 20 is positioned at and widens district 627 usually, so certain wearing and tearing of suction channel 14 (not expression among Fig. 6) usually occur in the terminal area 26 of suction slot 16.Here a wear-resistant and removable reinforcing member 630 has remedied this problem in a sense.In the case, reinforcing member 630 usefulness stopper shape alignment pins 631 and 632 are fixed on the suction channel of not representing on the figure 14.
See that from Fig. 6 the incision that is arranged in reinforcing member 630 constitutes widens district 627, it is slightly smaller than the otch that is arranged in suction channel 14 below it.
