Description

The device that is used for the detaching roller of pressure-loaded combing device

The present invention relates to a kind of combing device that is used for the noil material as described in the preamble according to claim 1.

Just developed a kind of combing machine in 1845, wherein in order to implement the segregation section mating reaction of separation process detaching roller and combing roller by Heilmann.On rolling up/the 5 edition the 167th to 174 page, the cotton spinning handbook second of Otto Johnsen can know, the roller that the fibre bundle that is separated with the segregation section mating reaction by detaching roller (herein for separating the pressurization roller) is delivered to subsequently is right, and it is connected or joins on the fibroreticulate end that has formed herein.This moment, roller was to driving with Pilger motion (intermittently paces motion).That is, with the tow transport of new taking-up to roller to before, this roller is to driving on opposite rotation direction, a part amount is back carried in the fibroreticulate end that has wherein formed on against the throughput direction of reality.In case this process finishes, the leading section of new fibre bundle just is placed into or overlaps onto on the end that fibroreticulate quilt back carries by (roof tile type ground).During right ensuing the travelling forward of roller, this overlapping region enter into roller right clamp together line, carry out fibre bundle thus with the bonding of fibroreticulate end or engage.After separation process finishes, certain amount of the fleeces band that roller will get off by unwinding on the volume that provides is provided is supplied with the clamp of opening.The length of fiber coma that protrudes in the bite (clamp joint point) of clamp has thus increased the amount of supplying with, and this amount is used for carding process subsequently under the clamp situation of ensuing closure.After the carding process of the combing sector by the combing roller, the fiber coma by the end of combing at the bite that is directed under the effect at segregation section under the situation of the clamp of opening again between detaching roller and the segregation section.All fibers that are held a clamping are taken out from present fiber coma then.The coupling that makes device and different fibrous material wherein is not provided.

By the known another kind of embodiment of CH-PS150873, it is worked according to Heilmann principle (the segregation section mating reaction on detaching roller and the combing cylinder).Wherein show various embodiment variant.In a solution, grip module is bearing in the frame regularly, and implements horizontal movement with respect to grip module with the cooperative detaching roller of segregation section during combing process.In the solution of another proposition, detaching roller is only diametrically towards the combing cylinder motion, and grip module moves towards detaching roller in the horizontal direction.In response to the spacing between the bite of this and clamp and detaching roller this combing process and separation process are coordinated better mutually.Be bearing in the sleeve terminal this moment of detaching roller, and this sleeve is contained in the Y-piece.Additionally the hook that loads by weight loads sleeve, to realize the clamping action of detaching roller.Wherein hook and the mechanical spring loading of detaching roller through correspondingly being provided with thus.

The foregoing description has very many moving components, and they have greatly restriction to realizing high combing period (speed).In addition, aspect high combing period, the action of the charger of shown detaching roller is slower and more dumb.The expensive time is wanted in the adjusting of chucking power, in the time of especially must implementing to regulate on a plurality of combing heads of working side by side mutually.

Do not know also that from known document the distance between clamp and detaching roller can regulate about traditional Heilmann method (it is identical that the spacing between hard-wired grip module and the detaching roller keeps).That is must suppose not to be provided with in this embodiment adjusting to " Ecartement(spacing) ".Term " Ecartement " uses in current combing machine and determines minimum range between the bite of the nipper plate of clamp and detaching roller.

The size of Ecartement finally be identified for carding process from the length of the outstanding fiber coma of the clamp of closure and thus the size of noil share (part of the fiber that is come out by combing) is had direct influence.

But this adjusting is absolute demand in the combing machine in modern times, so that realize being used for the quality of hope of the combing machine ribbon of operation stage subsequently.Especially also need accurately to regulate the noil share aspect the prices of raw and semifnished materials, so that avoid especially good fiber (long fiber) of unnecessary separation, and this can cause output to descend.

The adjusting of Ecartement is with to offer the fibrous material that combing machine handles relevant.Structure (the fibrage of main component (fibre length part) and the fleeces that provides need to be provided such as fleeces weight this moment; Uniformity) standard such as.

Other also can be from list of references " Kurzstapelspinnerei: volume 3:K mmerei, Strecken, Flyer " about information of notion " Ecartement ", obtains on the 16th page of the The Textile Institute (ISBN3-908.059-01-1).

Also show a kind of detaching roller in DE-PS528653, the segregation section co-operation of it and combing tube (combing cylinder) is carried out separation process.In order to produce chucking power, also use the spring or the weight of machinery herein.Project organization herein also comprise much more very mechanical organs and when it must be used for high combing period its action slower.With respect to today about large-duty requirement, also very low in the desired at that time combing period of described publication.

Therefore the objective of the invention is to improve the known design structure, wherein according to the segregation section cooperating of Heilmann principle detaching roller and combing cylinder.Especially in the case improve the known charger of detaching roller, even so that in the function validity that under current combing period, also guarantees them under the high dynamic load.

As seeing from Fig. 1 equally, lever 12 is fixedlyed connected with lining 21 on its end, lever by the rotatable motion of lining be bearing in illustrated the axle 13 on.Above bearing element 11, (roughly look up), on the lever 12 of correspondence, exert pressure by bellows cylinder barrel (telescoping cylinder) B1 and/or B2 in axle 15 the footpath of combing cylinder 16.The bellows cylinder barrel B1 and/or the B2 that respectively have its central axis a are bearing on the supporting surface 28 of lever 12 by its front end face 30 at this moment.Bellows cylinder barrel B1, and/or B2 has extension 31, this extension is charged in the opening 33 of supporting surface 28 for the side is stable.

On the opposing ends of front end face 30, bellows cylinder barrel B1 and/or B2 are bearing in the head piece 35, apply compressed air through valve 42 to service 37,38 from compressed air source 40 simultaneously on it.Valve is controlled by control module ST through pipeline 43 for 42 this moments.Settle retainer 36 on the head piece 35 of correspondence, this retainer is fixed on the framework 24 by screw 44.Frame parts 24 (Fig. 3) is by pole V1, and V2 interconnects.Other this pole also can be set be used for mechanically stable.

Move to the position shown in the dotted line by detaching roller 8 is moved to spacing E1 from spacing E, also moved lever 12, the bearing element 11 of its supporting detaching roller.The opening 33 that also moved shown in dotted line thus, this opening is admitted corresponding bellows cylinder barrel B1 and/or the extension 33 of B2.Because bellows cylinder barrel B1, B2 is installed in rigidly on the framework 24 through separately head piece 35 and retainer 36 and (also can directly be placed on the frame MS), during mobile detaching roller 8 is to the position shown in the dotted line, corresponding bellows cylinder barrel B1, and/or the central axis a of the B2 angle z that pivoted.Because the pliability of bellows cylinder barrel, this pivot with angle z can be compensated and be allowed under the function that does not influence the bellows cylinder barrel, up to a limiting value of this angle.Guarantee to be used for the adjusting device of each detaching roller 8 and a kind of simple combination of charger thus.That is to say, when regulating Ecartement (for example from E to E1), do not need additionally to regulate again the supporting-point (35,36) of charger (bellows cylinder barrel).By using the bellows cylinder barrel also can compensate the manufacturing tolerance of existence without a doubt.

As also seeing from Fig. 1, framework 24 can be pivotally secured on the frame MS around pivotal axis 46.Be pivoted on the position of a top around axle 46 by framework 24, shown in chain-dotted line among Fig. 1, can be free near the zone of grip module 1 to safeguard and to clean.For the position (run location, inoperative position) of the correspondence of fixed frame, for example framework 24, or on cross support arm V1 cam 48 are set, and they are inserted into and are fixed on according to the position among the blocking device 50a and 50b of structure correspondingly. Blocking device 50a, 50b comprises the lock pin 52a with oblique working face respectively this moment, or 52b, they are fixed on the frame MS.Lock pin 52a, this of 52b fixedly is such, promptly lock pin can move certain amount at lug 48 lockings or when unclamping.This moving under the power that overcomes the spring of correspondingly arranging 55 carried out, and this spring also is supported on the frame MS.By the lock pin 52a that has described and show at Fig. 1, the oblique working face of 52b, release or be locked on the position of correspondence smoothly.Also can realize many embodiment variant schemes herein, be used for the position of frame fixation in correspondence.

Avoid extension 31 from corresponding opening 33, to skid off when upwards being pivoted among Fig. 1 the position shown in the chain-dotted line at framework, a U-shaped backstop 58 respectively is set, at its following seamed edge 61 of supporting surface 60 upper support levers 12 at framework 24.That is to say that the backstop 58 by correspondence prevents the pivoting action of lever 12 around its axle 13, when the position that upwards is pivoted to shown in the chain-dotted line because the weight of detaching roller and this pivoting action may take place.As can from Fig. 1, seeing, have very little spacing on the run location of supporting surface 60 shown in this and between the following seamed edge 61 of lever 12, therefore do not stop by bellows cylinder barrel B1, B2 exerts pressure to detaching roller 8.

Can also see that from Fig. 1 the fibre bundle P that extracts out by the effect of clamping line KL is placed to fiber non-woven material (fiber web) V that forms at rotary screen (screen drum) T last and be stitched together with it with partly overlapping from fiber coma FB.The fiber non-woven material V of Xing Chenging takes out and flows to a device that is used to form fiber strip that is not shown specifically through taking out roller 64 from rotary screen T like this.In order to guide fiber non-woven material V, on rotary screen T, apply negative pressure.Rotary screen T, or be used to form the device of the fiber non-woven material of combing for example can be corresponding to the structure that in disclosed WO2006/012759A1, is shown specifically and describes as it.

As schematically illustrating at Fig. 1, during separation process, wherein detaching roller 8 by its side face U2 on the circumference U that is placed on segregation section 20 under the pressure-loaded, fixing comb K with from the outstanding fiber coma FB engagement of clamp 4.The back end that is held line KL seizure fiber firmly this moment is pulled by fixing the card clothing of combing K and being combed out.As already described, through bellows cylinder barrel B1, B2 exerts pressure to detaching roller 8, and this bellows cylinder barrel is loaded compressed air through valve 42 from compressed air source 40.This control module ST control by schematically illustrating.This moment also can be at a combing cycle period change pressure.

The locking system 50a that framework 24 is remained on the run location is designed in this wise, makes by through bellows cylinder barrel B1 B2 applied pressure and any automatic release can not take place at run duration.Additional element (not shown) will be set under certain situation, thus the pressure of opposing bellows cylinder barrel and framework 24 is locked on the run location reliably.

Go up (also referring to Fig. 3) in the position shown in the figure 1, the spacing between the periphery U1 of cam disc 22 and the periphery U2 of detaching roller 8 is very little.Detaching roller 8 and segregation section 20 can be formed for the clamping line KL of gripping fibers material F thus.Fibrous material F can be the form of sliver or the form of the fiber strip that is set up in parallel mutually (cotton-wool volume, bucket) supplies to grip module 1 from a corresponding source.When combing cylinder 16 continues rotation, segregation section 20 is in the active region of detaching roller 8 external movement, detaching roller 8 is by bellows cylinder barrel B1 thus, the pressure of B2 or its deadweight (as long as be reduced by the load of bellows cylinder barrel applied pressure) are moved along the axle 15 towards combing cylinder 16 radially, cling to up to the periphery U2 of detaching roller on the periphery U1 of cam disc 22.Cam disc 22 this moment by lining 23 anti-rotation ground be fixed on combing cylinder 16 spools 15 on.Schematically illustrate as Fig. 3, segregation section 20 also can be fixed on to anti-rotation on this lining 23.As seeing from Fig. 2, combing sector 19 enters in the zone of grip module 1, and grip module is closed and form bite KS by the device that is not shown specifically during this period, is used for hanging the fiber coma FB that from clamp.Fiber coma FB and combing card clothing 19 mesh and are combed out.The radius R 1 of cam disc 22 guarantees thus that greater than the radius R K of the external envelope face of combing sector 19 the periphery U2 of detaching roller 8 has a spacing during the combing process shown in Figure 2 and between the external envelope of combing sector 19 circle.Grip module is opened and fiber coma FB rises and enters thus in the zone of the clamping line KL between segregation section 20 and the detaching roller 8 for separated section 20 once more after combing process finishes.Because the corresponding design of the periphery U1 of cam disc 22, the periphery U2 of detaching roller 8 contacts with segregation section 20 again.Be accelerated in the time of during detaching roller is in and rotatablely moves continuously and thus needn't be on carrying out the transition to segregation section, this helps realizing separation process stably smoothly.Separation process begins now again, and wherein fixing comb K enters engagement again.

Schematically illustrated the combing device (being called for short " combing head ") that a row is arranged side by side mutually among Fig. 4, they dispose the detaching roller that can regulate 8 respectively, as what show in the structure of Fig. 1.The position of each pivotal axis 13 of pivotal arm 12 is regulated by lining 66 at this, and this lining is connected with corresponding pivotal axis 13 and with each servo motor M1 to M4.Servo motor M1 is connected with central control unit through control circuit 70 through control circuit 68, servo motor M3 and M4 with M2.Thus at adjusting device S1, S2, and/or S3, the control of S4 forms two groups of I and II combing head K1, K2, and K3, K4.Only show four combing heads in example, wherein the combing head of many many quantity can be provided with mutually abreast in practice.

Axle 13 can be bearing in correspondingly (not shown) in the guide of design in frame MS, pivotal arm 12 and thus detaching roller 8 can move through guide.The guiding mechanism (for example transport platform) of fiber strip F1 to F4 through not illustrating that forms on each combing head K1 to K4 and export is supplied to the drafter of back.Also show additional fibers yarn F5 to F8 in this example, they are exported by the other combing head K5 to K8 that does not illustrate.In drafter S, fiber strip F1 to F8 is drafted and be combined into fiber strip, and it is stored in the bucket through the form of a fiber strip storage unit that does not illustrate with ring.

By suggestion with adjusting device S1, S2 and/or S3, the control of S4 marks off two groups I and II, can adjust the different position of detaching roller 8 by group ground.Just can need during the different fibrous material of this combing in the combing head of each group.Then can produce the mixture with different fibrous materials on combing machine by this device, this mixture is mixed mutually at the drafter S of back.Also can consider a kind of embodiment in the case, wherein respectively supply with a different fibrous material to each adjacent combing head, thus can after reach better mixing in the drafter that connects.This moment, fibrous material can supply to each single combing head with the form of a plurality of fiber strips of pulling out from the bucket that supplies to combing head.

Term " by group control " also comprises a kind of embodiment, wherein combing head only forms a group, each combing head K1-K8 respectively is furnished with a servo motor S1-S8 and is used for regulating simultaneously detaching roller 8 in this group, and wherein all servo motor S1 to S8 are controlled by central control unit simultaneously through a public control circuit (not shown).

Can realize simple adjusting possibility by the device of suggestion to different fibrous materials.In addition, by the independent control to each single adjusting device of detaching roller, can handle different fibrous materials simultaneously, it can be mixed in follow-up drafter on the combing machine.By using the bellows cylinder barrel can realize saving the charger in space, it comprises other advantage, as damping, reduces noise, the pressure-loaded of control and compensation manufacturing tolerance.
