Description
Technical field
The present invention relates to a spinning machine with many adjacent arranged spinning spindle positions, each spinning spindle position has one with the drafting system of the front roller of jaw line before a pair of formation and collecting one that is positioned at the drafting system downstream set district of drawn fiber bar, the ventilative conveyer belt of a conveying fibre rod is contained in this set district, the latter is subjected to a slide guide face guiding that has a suction slot, the slide guide face of many conveyer belts is mounted on the suction tube that extends to many spinning spindle positions, and is projected into by front roller in the wedge gap that constitutes.
Background technology
And then the bar of drawn fiber in drafting device for spinning machine obtains spinning twisting.If this spinning twisting directly applies after drawing-off, may be at the front roller of drafting system to forming a so-called spinning triangle, this triangle contains the inappropriate edge fiber that is attached in the twisted yarn.For fear of this shortcoming, in recent years in a so-called set of the arranged downstream district of drafting system, drawing-off but untwisted yarn are assembled and boundling or set by the avris of its single fiber in this set district, thereby the no longer appearance under another jaw line situation of arrangement of imperfect spinning triangle.The ribbon of gathering under this mode obtains its spinning twisting, and the yarn filoplume that is spun into is less, and is even and powerful good.
The prior art of above-mentioned this spinning machine can be learnt from German patent DE 199 03 113 A1.Extend to many spinning spindle positions, for example the suction tube of a joint fine spining machine has a kidney shape cross section, and it extends to front roller in the wedge gap that constitutes.Each spinning spindle position is provided with the stiffener of the thin metal foil of about 0.2 to 0.5 millimeters thick on suction tube, wherein the suction slot that is in the suction tube of each spinning spindle position also is to extend by metal forming.The surface of metal forming is formation slide guide face in set district, and this slide guide face is being followed a minimum spacing of suction tube outline.If the front roller that the slide guide face in each set district directly originates in drafting system is to being comparatively favourable in the wedge gap.This spinning machine known to everybody, also there is shortcoming in suction tube under the situation that does not have stiffener between two spinning ingots, because the very small thickness of metal forming, suction tube also is directly to extend to each front roller.Its shortcoming is, mainly be can set fiber between each spinning spindle position, but fiber not can be incorporated in the ribbon when set for some reason.These discrete single fibers may at a time not have control to enter in the ribbon down and/or are blocked in the eyelet of ventilative conveyer belt, thereby influence the set effect gradually.
Summary of the invention
Task of the present invention is that above-mentioned this spinning machine roughly is in two discrete fibres between the spinning spindle position can be disposed from this zone easily.
The solution of this task is, suction tube be placed in from front roller to a determining deviation in, and the slide guide face of band suction slot is to be placed on the single cover that can be fixed on the suction tube, single cover is connected across the spacing between suction tube and the wedge gap.
According to this technical scheme, between per two spinning spindle positions, provide an enough big intermediate space between suction tube and preceding bottom roll.Produce big cleaning gap by aforesaid way, discrete fiber may be walked and be fallen and from the critical zone, for example cleaned by a touring cleaner.By means of feature of the present invention, between the spinning ingot, form an enough big gap that is used to keep clean.Single cover can all be used the plastics manufacturing, and it is pushed on the suction tube that is designed to this round tube of foundation.In any case single cover must prevent reliably that avris from moving and rotate.
Therefore be preferably in and settle the avris spigot surface that is used for each conveyer belt on each single cover.Its advantage is that conveyer belt accurately is subjected to the avris guiding in the collection area of reality.
The bigger suction hole of suction tube configuration on each spinning ingot is advantageous, and suction hole is covered after having assembled single cover, and interacts with the suction slot that is loaded in the single cover.For the suction hole in the suction tube, do not need big tolerance, and to spinning technique important be in suction slot in the slide guide face, can when making single cover, together assemble with plain mode.
Single cover preferred design becomes hollow profile, and it has the avris cover.The boring that single cover is used for being pushed on the suction tube is capped.Reached desired sealing between suction tube and the single cover so simultaneously.
In a technical scheme of the present invention, the rotaring forward roller of guiding conveyer belt can be installed on each single cover, and slewing rollers are to be driven by a friction roller.This type of drive is sent to conveyer belt with enough big friction, and don't makes conveyer belt cause uncommon wearing and tearing.Define the clamping roller of gathering the district at outlet side, it plays driving the conveyer belt effect, and no longer is used as transmission now, and just play the only sth. made by twisting effect between set and the twisting mechanism on the spinning machine according to above-mentioned technical merit.
Description of drawings
Other advantages of the present invention and feature can be learnt from following examples of implementation and the description of the drawings.
A collection area partial cross section side view of a spinning spindle position of a spinning machine of Fig. 1;
Fig. 2 is according to the view on the set area of Fig. 1 arrow II direction, and some parts among the figure particularly are positioned at the top pressurization roller in set district and dispense.
The specific embodiment
According to the spinning machine shown in the part of Fig. 1 and Fig. 2, at first be a ring throstle, common this spinning machine vertically has the spinning spindle position of many adjacent arrangements by machine, can see three spinning spindle positions 1,2 and 3 from Fig. 2.
Each spinning spindle position 1,2,3...... have a drafting system 4, but only draw its terminal area in Fig. 1, and a boundling drawing-off but the set district 6 of untwisted ribbon 5 are arranged, and the set district is positioned at the downstream of drafting system 4. Spinning spindle position 1,2, other assemblies of 3...... do not illustrate.
Each drafting system 4 has a pair of front roller 7, and is installed in the apron roller 10 of front roller to apron 8 and upper leather ring 9 under the guiding of upstream.All the other rollers of drafting system 4 are not to giving expression on the figure.
Front roller has one to extend to many spinning spindle positions 1,2 to 7, and driven bottom roll 11 of 3......, bottom roll are at spinning spindle position 1,2, and there is the trench area 12 known to everybody at the 3...... place.At each spinning ingot 1,2,3...... is generally and settles a pressurization roller 13 on the trench area 12 of bottom roll 11.Jaw line 14 before front roller is determined 7 is at the draw zone of this place's termination drafting system 4.Under known way, feeding fibrous material 15 is drawing to desired number by throughput direction A such as a branch of ribbon or rove in drafting system 4, and drawing-off stops on preceding jaw line 14 basically.
Owing to these above-mentioned reasons, set district 6 is the downstreams that are placed in drafting system 4, and still untwisted ribbon 5 avris by its single fiber in the set district is assembled and boundling or set.
The ribbon 5 that each set district 6 has a ventilative conveyer belt 16 to gather is carried by set district 6.Preferably select a kind of flimsy material band that fine meshed is arranged for use about conveyer belt 16, gas permeability is promptly produced by fabric self.
Every conveyer belt 16 is directed through a slide guide face 17, this slide guide face also will be described in detail in the literary composition afterwards, is that the appearance profile by a single cover 18 constitutes, and this single cover and other single cover 18 all are installed to one and extend to many spinning spindle positions 1,2, on the suction tube 19 of 3.......Suction tube 19 is in low pressure and is connected on the figure the not low pressure source of expression via a low-pressure connection tube 20.
A clamping roller 24 is placed in the terminal of each draw zone 6, and clamping roller and each slide guide face 17 form one and export jaw line 25, and suction slot 21 extends to this jaw line 25, and the latter forms one to spinning twisting and ends sth. made by twisting.And then yarn 26 is produced at output jaw line 25, and this moment, yarn was to enter into the twisting mechanism of not representing on the figure by throughput direction B, and for example one is encircled on the ingot.Clamping roller 24 stops the spinning twisting that is applied to yarn 26 to get back to set district 6 again.
Being described by the bottom roll 11 of transmission and other or the bottom roll of illustrated drafting system 4, generally is the longitudinal extension by spinning machine, all press on the bearing of the drafting system that actual spacing supporting do not represent in the drawings.
Slewing rollers 23 be directly installed on bottom roll 11 near, and form a wedge gap 27 with bottom roll.A friction roller 28 that is bearing in the device seat is positioned in this wedge gap 27, its flexibly reclining bottom roll 11 and slewing rollers 23.Friction roller 28 is to be driven by bottom roll 11, and 23 of slewing rollers are by frictional drive, also drive conveyer belt 16 simultaneously.For this reason, friction roller 28 should use a kind of suitable lining face.Especially see two parts of operation, i.e. friction roller 28 and slewing rollers 23 simultaneously being arranged at the frictional drive point from Fig. 1.Though frictional drive needs certain pressure, reality does not produce wearing and tearing on conveyer belt 16.Niproll 24 is by conveyer belt 16 transmissions, only need have generally in the zone of output jaw line 25 can guarantee only to twist with the fingers desired pressure towards slide guide face 17.
As can be seen from Figure 1, front roller constitutes a wedge gap 29 to 7 in its this side towards set district 6, and each slide guide face 17 stretches into wherein.Each slide guide face 17 technically as far as possible the location but do not touch bottom roll and ribbon 5 nothing in the zone of wedge gap 29 that should gather obviously turns near the zone of jaw line 14 and bottom roll 11.Such arrangement shows that the yarn 26 of production has good especially quality.The location should be closely, only stays a minimum gap between each slide guide face 17 and relevant preceding jaw line 14 and the bottom roll 11.
Slide guide face 17 close positioning arrive front roller to 7, the discrete fibre that helps the least possible generation to separate from ribbon 5.If still produce discrete fibre, must prevent that then these fibers from entering into ribbon 5 again under nothing control.Therefore the setting as a feature of the present invention is at per two spinning spindle positions 1,2, an enough big gap 30 to be arranged between the 3...... between bottom roll 11 and suction tube 19.Gap 30 should be selected enough big, makes any discrete fibre easily by falling into and these fibers can exclude in the critical zone between the 3...... from two spinning spindle positions 1,2.
If bottom roll 11 contacts with conveyer belt 16 at a point 31, cleaning effect can give reinforcement, because bottom roll 11 and conveyer belt 16 are to move by opposite direction at this place.Add so a kind of mechanical cleaning conveyer belt 16 is provided.
According to the spinning machine of prior art, touched upon in the front extends to many spinning spindle positions 1,2, and the suction tube of 3...... is to be designed to extend to wedge gap 29 always.But enforcement of the present invention then is not this situation.
According to Fig. 1 and Fig. 2, each spinning spindle position 1,2 all is provided with a single cover 18 on the 3......, and single cover contains the slide guide face 17 of being with suction slot 21 and is pushed into one and extends to many spinning spindle positions 1,2, on the suction tube 19 of 3.......Single cover 18 is designed to hollow profile 32, is with two avris cover caps 33,34.Boring is positioned in two cover caps 33,34, and the diameter of bore diameter and suction tube 19 is complementary.So just obtain a sealing between suction tube 19 and each the single cover 18 simultaneously.
Because each slide guide face 17 is placed on the single cover 18, now suction tube 19 just can be installed to from front roller to a determining deviation of 7 in.Single cover 18 contains the slide guide face 17 of being with suction slot 21, and the gap between cross-over connection suction tube 19 and the wedge gap 29 is different with prior art.Per like this two spinning spindle positions 1,2 produce a bigger gap 30 between the 3......, this gap is the restriction that is subjected to bottom roll 11 and suction tube 19.This big gap 30 is used to keep per two spinning spindle positions 1,2 of spinning machine, the cleaning between the 3......, thus make discrete fibre can not under the control situation, enter the ribbon 5 that should gather.
Owing to single cover 18 the most handy plastics manufacturings, it can be provided with avris yarn guiding surface 35,36 with plain mode and mainly lead in the zone in set district 6 as conveyer belt 16.
