At the output of the drafting system of the disclosed ring spinner of structure, if it should equip the spinning twisting apparatus, then on the fiber strip of drawing-off a kind of so-called spinning triangle can appear.Its reason is that the fiber strip of drawing-off has certain obviously above the width that has spun fibre diameter.The triangle that wherein spins comprises that those do not have or enough are not incorporated into edge fiber in the fiber of having twisted, thereby this is to the not contribution of intensity of the yarn that has been spun into, and perhaps contribution is very little.
Recently, set up so-called aggregate device for fear of the generally popular employing of alarming spinning triangle in the back of drafting system, the fiber strip that it does not have drawing-off twisting is by opposite side fibrae marginatae side direction and close boundling or the set of carrying out this form, at last jaw line place, the spinning triangle appears no longer before twisting promptly.For example, according to DE19838762Al, a kind of ring spinner with this aggregate device is exactly a prior art.At this, this aggregate device includes a fixing air intake passage, and this passage is provided with a series of suction slot.Moving a ventilative sieve band on each air intake passage, this sieve band is carried fiber strip to be gathered by the set district.At this moment, a gripping roller that drives the sieve band has formed last one jaw line with this air intake passage, and from then on line rises fiber is twisted.
DE19756393Al also discloses the drafting system bearing spider of the ring spinner of design like this, and promptly ring spinner selectively has or do not have the operation of aggregate device ground.Therefore, when not having the work of the ring spinner of aggregate device and when needing the drafting system bearing, those drafting system bearing spiders that originally were used for this repacking just additionally have a bearing block in order to make.People can be provided with the bottom roll of drafting system in this wise, and promptly ring spinner is when the operation of no aggregate device, and all places that enters each drafting system at fiber strip just comprise a untapped bearing block.Having the aggregate device operation time to use all bearing blocks then, wherein to hold a roller that belongs to aggregate device right for last bearing block on drawn fiber yarn throughput direction.
Summary of the invention
Task of the present invention is can be later on to give for the first time the sort ofly not install aggregate device additional with the ring spinner of aggregate device and the conventional structure mode that neither prepare for repacking.
For this reason, the invention provides the method for a drafting system bearing spider of a kind of repacking, the drafting system bearing spider has the bearing block that several are arranged before and after on the fiber strip throughput direction, bearing block is furnished with the semi-cylindrical groove that is of a bearing that is used for the drafting system fluted roll respectively, wherein take down the bearing of last that bearing block on the fiber strip throughput direction, replace one and pass the adapter that becomes idle groove and be used to hold a fixing air intake passage, the front of the clutch shaft bearing seat on the fiber strip throughput direction replenishes an additional bearing block.
The present invention is based on following understanding, the conventional ring spinner of promptly selling on market in fact all has the drafting system bearing spider that both had been applicable to the long fiber scope and also had been applicable to the staple fibre scope as any product.So, in the staple fibre field, the drafting system bearing spider of ring spinner is all excessive usually, and this is relevant with drafting system bearing spider length.Because people mainly are thought of as the staple fibre zone and install aggregate device additional, so all ring spinning mechanisms of in fact selling on market all can install additional according to mode of the present invention.By on the fiber strip throughput direction, increasing the clutch shaft bearing seat, move backward by disclosed mode bottom roll itself then drafting system.According to the present invention, become idle bearing block and hold an adapter, adapter is so prepared, and fixing air intake passage can be retrofitted on also disclosed aggregate device itself.
Be equipped with corresponding roller should for again certainly the drafting system fluted roll that has been shifted.For example this can be achieved by a new roller pressurized cradle.Yet, if people want to keep original drafting system pressurized cradle, then, a corresponding supporting arrangement makes a clutch shaft bearing seat roller pressurized cradle rotating shaft reposition in front that on the fiber strip throughput direction, is arranged on the drafting system bearing spider originally by being installed afterwards.For example, always not necessarily to be connected on the existing negative pressure channel of original ring spinner at the air intake passage that installs additional that moves on the machine section.But all can obtain oneself a compressor by the air intake passage that each machine section installs additional, this compressor also is directly to link to each other with a drive motors.Usually, conventional ring spinner all leaves desired location for this reason.

The specific embodiment
To be installed additional and ring spinner that have conventional structure comprises many drafting systems 1 according to the present invention, and Fig. 1 schematically illustrates one of them drafting system.In this example, drafting system 1 be designed to three cylinder drafting systems and have an input roller to the apron roller of 2, centres to 3 and front rollers to 4.Like this, on the drawing-off direction of drafting system, three drafting system fluted rolls 5,6 and 7 and the roller 8,9 and 10 that belongs to them are arranged.
So-called drafting system bearing spider 14 is used to support the bearing of drafting system fluted roll 5,6 and 7, wherein for example along machine vertically by machine intersegmental apart from be provided with a plurality of drafting system bearing spiders.Each drafting system bearing spider 14 all has been equipped with the tandem bearing block 11,12 and 13 that is used for corresponding drafting system fluted roll 5,6 and 7.For this reason, each bearing block 11,12 and 13 all has semi-cylindrical recesses 15,16 and 17, and corresponding bearing 18,19 and 20 remains in these grooves.
Except the bearing block 13 of front, bearing block 11,12 can move in a guider 21 of drafting system bearing spider 14 and be fixed separatedly with desirable spacing usually.Like this, can make the distance of drafting system fluted roll 5,6 and 7 be matched with fibrous material to be spun respectively.In the ring spinner of routine, guider 21 is much longer compared with the required guider of particular application usually.
Roller pressurized cradle 22 is placed on each drafting system 1, they belong to respectively two adjacent yarning parts and thereby supporting two adjacent rollers 8,9 and 10 respectively, and roller itself all becomes known roller to form.The roller pressurized cradle is bearing in the rotating shaft 23 that is installed in the drafting system bearing spider 14 and can rotates.
In each drafting system 1, fiber strip or rove 24 are drawing to desirable fineness respectively in a known way.In this case, in drafting process, fiber strip 25 is pressed throughput direction A and is carried.At the end of this conventional drafting system 1, the yarn 26 of drawing-off is transported to a unshowned twisting mechanism as in the ring ingot by throughput direction B subsequently.
In the ring spinner of routine, to 4 jaw line place, already mentioned alarming spinning triangle had just appearred before yarn 26 is twisted directly at delivery roller.For fear of this phenomenon, task of the present invention is to install disclosed aggregate device on the ring spinner of routine additional, and the purpose that installs this aggregate device additional is that the last one jaw line place before twisting avoids occurring alarming spinning triangle.Stipulated for this reason, reequiped by following mode counter extensioin device bearing spider 14.
Figure 2 illustrates the drafting system 1 of having reequiped by the present invention of Fig. 1.In the figure, the member of having described just no longer has been described.
As can be seen from Figure 2, bearing takes down from bearing block 13, once uses this bearing according to Fig. 1 at this bearing block.Replaced before the former clutch shaft bearing seat 11 on the throughput direction A and to use an additional shaft bearing 27, as from can know the comparison of Fig. 1 and Fig. 2 see.Then, the bearing in the former bearing block among Fig. 1 11,12 and 13 18,19 and 20 is taken and is put into away the bearing block 27,11 and 12 of Fig. 2.Like this, the bearing 18,19 and 20 that is used for drafting system fluted roll 5,6 and 7 just and affiliated drafting system roller 5,6 and 7 move backward together.As can be seen from Figure 2, last that bearing block 13 on throughput direction A no longer supports any drafting system fluted roll subsequently.
Corresponding to drafting system fluted roll 5,6 and 7 movably, affiliated roller 8,9 and 10 also moves backward, and like this, they continue to be attached to its corresponding drafting system fluted roll 5,6 and 7.As can be seen from Figure 2, so, whole roller pressurized cradle 22 moves backward, and simultaneously, former rotating shaft 23 has obtained a reposition 28 now.This realizes by a new support 29 that is arranged in the drafting system bearing spider 14.In Fig. 2, represent the displacement size with X.
Because it is very long that original guide design in each drafting system bearing spider 14 gets, so the bearing block 27,11 that the repacking back exists can be by waiting that spinning the different of fibrous material is adjusted to required mutual spacing and is fixed on correct position with 12.
As can be seen from Figure 2, subsequently an adapter 30 is attached in the groove 17 of change free time of bearing block 13, the outline of this adapter be half-cylindrical basically and and become that idle groove accurately mates and this position that is fixed on.As the back also will narrate, adapter 30 comprises the groove of a upper shed, an alignment pin 31 of a fixing air intake passage 32 can be installed in this groove.This will describe in detail in conjunction with Fig. 3-Fig. 5 in the back.
As from Fig. 2, seen with the back will in following figure, be described in detail, after installing additional, drafting system 1 has a set district 33 after being positioned at draw zone respectively, in this set district, to drawing-off but also untwisted fiber strip gather.For this reason, one of additional installation grips roller 35 on roller pressurized cradle 22, and this grips roller and is driven by roller 10 by delivery wheel 36.Then, grip roller 35 and form another jaw line with air intake passage 32, thereby, alarming spinning triangle no longer appears on this line.
Now, describe in detail immediately following behind drafting system 1, installing 33 zones, set district additional by Fig. 3 and Fig. 4.
Behind device 39, also promptly after gripping roller 35, yarn 26 to be twisted is transported in the unshowned ring ingot along throughput direction B.
The aspirating air pipe of having mentioned 32 that installs additional is attached troops to a unit to many yarning parts of from 40 to 43, a section in eight yarning parts for example, and air intake passage 32 is parts of aggregate device 39 and is designed to hollow special pipe shape.It may be a kind of little special pipe of being made by light metal or noble metal of friction, perhaps also may be a kind of wear-resistant and strong plastics special pipe of slickness.This air intake passage 32 is totally enclosed except opening also to be illustrated and is under the negative pressure.Each air intake passage 32 is bearing in the drafting system bearing spider 14 by later mode also to be illustrated replaceably at its end.In drafting system bearing spider 14, also supporting drafting system fluted roll 5,6 and 7.
The last profile of aspirating air pipe 32 is designed to some sieves with 44 gliding movement targeting structure, wherein attach troops to a unit respectively some in yarning part 40-43 of each sieve band.Sieve is very thin and have the woven endless in superfine hole bands with 44, and therefore, sieve is breathed freely with 44.They are as the conveyor surface of fiber strip 34 to be gathered.
With delivery roller to 4 separatedly, as the distance ground that equals fibre length according to one, every bar grizzl(e)y band is pressed to aspirating air pipe 32 with a driven gripping roller 35.For this reason, smaller pressure such as 20N are just enough.So, each sieve is with 44 to be driven slidably on aspirating air pipe, and sieve is carried drawing-off and fiber strip 34 to be gathered again with 44.
The driving that grips roller 35 is by delivery roller 4 roller 10 to be derived.By transmission gear 36, fiber strip 34 to be gathered in fact obtained at jaw line 45 places that grip roller 35 with at delivery roller to 4 the identical speed in jaw line 46 places, increased because of a little tension drawing-off speed at the most.
No matter be delivery roller to 4 roller 10, still grip roller 35, they are installed on the balladeur train, and this balladeur train bears the power of at least one loading spring of roller pressurized cradle 22.For this reason, consider to make the load of roller 10 greater than the load that grips roller 35 by corresponding geometry.
With the quantity of the yarning part 40 to 43 of subsidiary air intake passage 32 adaptably, hollow special pipe comprises many suction slots 47, these suction slots are with 44 to cover by affiliated sieve respectively.The starting point of suction slot 47 is immediately following at delivery roller 4 jaw line back and suction slot are extended to the jaw line 45 that grips roller 35 always.The relative throughput direction A of the trend of suction slot 47 certain angle that tilts so just give 34 1 little false twistings of drafted fiber strip of carrying by suction slot 47, and the effect of this false twisting pair set is helpful.
Big centre between two drafting system bearing spiders 14 has disposed a suction hole 48 for each air intake passage 32, and this suction hole is connected with a vacuum source that only schematically illustrates 49.That is to say that each air intake passage 32 has only unique suction hole 48.
Just as already mentioned, be used to gather drawing-off but the attachment device 39 of untwisted fiber strip 34 can make last jaw line 35 places before twisting alarming spinning triangle no longer occur becomes possibility.
Referring to Fig. 4, now describe air intake passage 32 in detail and be fixed on two situations on the drafting system bearing spider 14 by enlarged drawing 5.
As in Fig. 4, only illustrating and can be as can be seen clearly from figure 5, each air intake passage 32 by being arranged on its end quick acting locking device 50 and be supported in by the adapter 30 of new use under in the drafting system bearing spider 14.Adapter 30 is equipped with a corresponding supporting base 51 with square-section, and this bearing block is the groove structure of upper opening, and a corresponding alignment pin 31 of air intake passage 32 can insert in this groove.The profile phase coupling of alignment pin 31 and supporting base 51, but in its terminal one-tenth ovalize or semi-cylindrical shape.By a clamping bar, every section air intake passage 32 is fixed in the supporting base 51 of adapter 30 by its alignment pin 31.
Each clamping bar 52 can rotate around a rotating shaft can packing into subsequently 53 of affiliated drafting system bearing spider 14, up to being blocked by block 54.The disengaged position 55 of clamping bar 52 dots.People can see flat clamping 56, and clamping bar 52 just is pressed in by this plane on the corresponding outline of alignment pin 31 when locking.Thereby, Braking mode appears.
If as the sieve belt wear of one of yarning position 40-43 or bad, then quick acting locking device 50 is used for the fast quick-detach of air intake passage 32.Be with 44 for changing certain sieve, clamping bar 52 changes its disengaged position 55 over to, like this, can upwards take out corresponding air intake passage 32 from supporting base 51.Then, just can easily replace the sieve of this replacing to be with 44 with 44 with a new sieve.Air intake passage 32 can be inserted again again in the drafting system bearing spider 14 and with clamping bar 52 and be pinned.
If should from ring spinner, take out set again with device 39, if the confidential original state that returns to it of i.e. ring spinning can be undertaken by corresponding mode.Only need to take away each adapter 30 and make each drafting system fluted roll 5,6 and 7 to return its origin-location as shown in Figure 1 together with fixing air intake passage 32.This way is equally applicable to the rotating shaft 23 of roller pressurized cradle 22.
