Description

Centrifugal spinning starts the method and apparatus of back yarn rewinding process behind yarn breakage

The present invention relates to a kind of method that starts back yarn rewinding process behind yarn breakage in a kind of one-step method centrifugal spinning, and the device of implementing this method.

Centrifugal spinning, particularly so-called one-step method centrifugal spinning generally adopts a rewinding bobbin to guide the yarn cake that is wound on the tophan box inwall to carry out back yarn rewinding process.Promptly when regular spinning process by a ready bare bobbin on yarn-guide tube, cross the guide mouth of pipe and down land, beginning back yarn rewinding process.This moment, barrel tip was seized the revolution sliver that comes out from yarn-guide tube, made the yarn cake that is wound on the tophan box inwall carry out the back yarn after-combustion to bare bobbin.

Certainly, in spinning process, promptly the yarn cake be formed into broken yarn the time can produce all difficulties.When one-step method centrifugal spinning, though behind a yarn breakage, can continue spinning, during back to back back yarn rewinding, spun yarn amount when also remaining with in the tophan box to yarn breakage, it can only be taken out after the tophan box stall usually.

The whole bag of tricks that past has developed and device it is said and can just can carry out the back yarn rewinding behind primary break with being wound on the interior yarn cake of tophan box, thereby spun yarn can further be processed.

Yet known most of this method and apparatus has various shortcomings, therefore fails to be put to practical application.

The method of example patent DE 4400999 A1 exploitation as known, promptly so-called two-step method pot spinning method.

This method is that a rough seizure yarn enters in the tophan box of rotation by yarn-guide tube under yarn breakage situation.Catch yarn along with the interior roll of yarn cake around and twisted, thereby and then catch yarn and move bootable back yarn rewinding process, the second step process that promptly enters this pot spinning method by drawing back.

The shortcoming of this method is, uses a kind of rough seizure yarn, because of this external yarn and must take out carefully.In addition, the functional reliability of this method is lower.

A kind of special bobbin is described in DE 19523937 A1 patents, a vertical end at this bobbin has a dish expansion of radially protruding, this common loose thread as string shape sliver utilizes this dish-shaped dilator to come to the inner surface of yarn cake, and the beginning back yarn rewinding process that is booked.

This special rewinding bobbin also can not be applicable to various yarns in practice.Concerning different yarn kinds, the extracting of using this string shape sliver that not too appears proves difficulty especially.

In addition, relevant with the tophan box spinning equipment, these devices of guiding back yarn rewinding behind yarn breakage, CH-PS 348346 and DE-PS 842916 are well-known.

A kind of Zhou shape instrument of Swiss Patent textual description for example, it is to enter in the tophan box of rotation with manual when yarn breakage, and contacts the internal layer of yarn cake with a thin detection wire connection.Contact yarn cake starting back yarn rewinding process by surveying wire connection.

In view of the high revolution of modern centrifugal spinning jar, the instrument that this manual mode can enter tophan box has tangible accident risk, and therefore, in order to prevent accident, this instrument has not allowed to use on now the spinning machine.

DE-PS 842916 has described a kind of lever apparatus that can enter tophan box that has, and this device can be regulated around the layer position in the interior roll of yarn cake.

This device has its defective really, when the back yarn rewinding, and the instrument of this separating draw thread, the bar that promptly abuts on the yarn cake also is wound simultaneously.At this moment the cop of Xing Chenging normally no longer can unwinding, therefore becomes waste product.

From above-mentioned technical merit, task of the present invention is to develop a kind of method and apparatus that can improve the centrifugal spinning back yarn rewinding process behind yarn breakage.

According to the present invention, the method that realizes this task is one-step method centrifugal spinning starts back yarn rewinding process behind yarn breakage a method, the spinning tophan box that system enters into rotation by the yarn resolution element clings on the yarn cake that is wound on the tophan box inwall and realizes, it is characterized in that, the yarn resolution element clings to the coiling cone of yarn cake by transmission mechanism, at this moment be installed on the feed carrier of a band guide profile of yarn resolution element, the coiling layer of yarn cake foot is risen to the height of rewinding bobbin, so that can prevent reliably that when the rewinding process yarn resolution element from being twined by yarn.

Realize the device of this task, be characterised in that the yarn resolution element has adjustable edge of a knife and the guide profile by the axial covering edge of a knife on the coiling cone position of yarn cake.

According to method major advantage of the present invention be, behind yarn breakage, can carry out back yarn rewinding process in no problem ground, at this moment, be wound on centrifugal tank skin and can not sustain damage as the spun yarn and the yarn resolution element of yarn cake.

In other words, after yarn separator guiding back yarn rewinding process, spun yarn, and is wound up on the rewinding bobbin immediately by axially moving up controllably by the guide profile of yarn resolution element.

The method has stoped the winding to the yarn resolution element reliably.

The preferred version of yarn resolution element design is that it parallels with spinning tophan box inwall and enters into tophan box, and nestles up the yarn cake at the lower area of coiling taper.According to said method, must can be reduced to a minimum, be reeled by yarn to prevent the yarn resolution element by the coiling layer number that the guide profile is promoted.

When guide profile during in guiding back yarn rewinding process, arrive at the nethermost winding layer of yarn cake, guaranteed that then all winding layers of yarn cake all are positioned on the rewinding position of it's robbin, avoided the yarn resolution element to be reeled fully simultaneously by yarn.

This method another preferably design be, when guiding back yarn rewinding process, affact the axial thrust load of yarn resolution element, collected by a power receiving device, and be used for taking place a signal.And then this signal in the central control unit of tophan box spinning machine, perhaps carries out following processing at a control device that belongs to single centrifugal spinning position, and soon sort signal is switched to the guiding back yarn rewinding process by rules.

In other words, when corresponding this blackout, can begin a new coiling immediately and attempt.

Rewinding process according to rules can be monitored, for example, when the rewinding process, affact the moment of torsion of rewinding bobbin, be to collect by a moment of torsion receiving system, this moment, the signal of moment of torsion receiving system can be on known rewinding coiling time basis, as the flow process in accordance with regulations of monitoring rewinding process on control device.

According to yarn resolution element of the present invention, can have a yarn pancake roll adjustable edge of a knife on cone, and one protrudes from the axial guide profile of the edge of a knife.

The guide profile has a suitable guide radian, and the bottom winding layer that this bending of process makes the yarn cake can make the yarn resolution element do not twined by yarn when the rewinding process all by suitable lifting.

Relate to the claim to a method that the front has been narrated, device according to the present invention has a power receiving system in the zone of yarn resolution element, it is collected, and yarn rises to the axial thrust load that the guide radian is produced in the rewinding process, and transmits a corresponding signal to control device by a signal line.A signal that promptly is placed in the power receiving system on the guide resolution element is estimated as the effective back yarn rewinding process that has begun.

In addition, in the zone that holds the rewinding bobbin, can be mounted with a moment of torsion receiving system, it surveys the moment of torsion that affacts in the back yarn rewinding process on the rewinding bobbin.The moment of torsion receiving system also is connected with control device by a signal line, therefore by the moment of torsion receiving system, and considers the coiling time, can monitor the rewinding process condition by plain mode.

Can make the more careful foot coiling layer that navigates to the yarn cake of yarn separator.

By this method, prevented that the yarn separator from gripping the overlapped yarn pancake roll of multilayer simultaneously around layer, as not being, can cause producing the cop of unwinding more usually.In addition, reclining that the yarn separator is excessive hard can produce following danger, promptly guides overturn moment to act on the spinning tophan box of rotation, and this moment loses synchronously the spinning tophan box of magnetic supporting, and the danger of generation is the other centrifugal tank body of starting tophan box housing.

Because the spinning tophan box of this magnetic supporting is that centrifugal tank body is done any mechanical contact with a stationary parts of rotary spinner and can be sustained damage, and therefore under any circumstance should avoid with high revolution rotation.

In a preferred embodiment, the yarn separator can be supported rotationally.The yarn separator can no problem ground under the situation of inwardly swing, enter in the spinning tophan box, and and then outwards swing, rest against the bottom layer of the yarn cake that the tophan box inwall is wound into carefully.

The yarn separator can make the yarn separator flexible by a power, promptly optionally situation can be flexibly with careful rotation.

The yarn separator is that this elasticity loading best way is to adopt electronic or pneumatic.

As adopt a pneumatic means, at this moment the yarn separator has the compressed air nozzle that can accurately control at least.By this compressed air nozzle that is loaded on yarn separator back, can on the yarn separator, load a reverse compressed air blocking surface, thereby make the yarn separator by the direction of yarn cake to locating swing.

The yarn separator resets to resting position, is to carry out by a flexible member or by second compressed air nozzle.When second compressed air nozzle was installed, the yarn separator was connected with two compressed air nozzles according to circumstances, can carry out inwardly or outwards rotating.Here the regulation and control of compressed air nozzle are by reliable 2/2 reversal valve.

This device is at first selected this design, promptly by straightforward procedure Pneumatic pressure can be regulated accurately, thus can produce the yarn separator towards the yarn cake near power.For example, on this root compressed air piping of the compressed air nozzle of extrinsic deflection, be connected with a throttling arrangement at guiding yarn separator.

Also can use an electric device to substitute above-mentioned pneumatic arrangement for deflecting.

This electronic arrangement for deflecting is installed on the yarn separator, for example is an accurately magnetic coil of power supply stream.Yarn separator itself is to make with ferromagnetic material to small part, like this by suitable to being installed in yarn separator turning cylinder top, or bottom solenoid energising far away as far as possible, the yarn separator can inwardly swing to its operating position.

By regulating current strength, the power of using a potentiometer just can the yarn separator be clinged on the yarn cake is here accurately regulated.The therefore careful inside rotation of energy of yarn separator, its contact momentum that relies on yarn cake winding layer can accurate being limited.

Advantageously, effectively the contact momentum can fine adjustment on the yarn cake to be not only the yarn separator, and also can be given in advance to the maximal regulated distance of yarn separator.In other words, get final product the operating position that is loaded on the edge of a knife outermost on the yarn separator given in advance by an adjustable link stopper, and can be proofreaied and correct at any time when needed.

The version of described a kind of feed carrier has guaranteed that the yarn separator is unlikely mistaken and twined by yarn in back yarn rewinding process, thereby will can not produce out of use cop.

Touch the foot coiling layer of yarn cake accurately by the edge of a knife of yarn separator, thereby guide back yarn rewinding process reliably and modestly.

Here the edge of a knife can be a different shape, be designed to pointed shape, rectangular, or similar shape.

Other details of the present invention can be learnt from following illustrated embodiment.

VI-VI the cross sectional plan view of the yarn resolution element of the present invention's design is pressed according among Fig. 4 by Fig. 6 system.

Fig. 1 has showed the overall rotary spinner schematic diagram that indicates with label 1 of an of centrifugal spinning machine of not representing in detail.All be known to everybody on this class centrifugal spinning machine principle, for example in DE 19637270 A1, done detailed description.

This rotary spinner generally occupy one rotatable in the housing 2 in spinning, and be bearing in spinning tophan box 3 on the bearing 4.More superior mode is that this centrifugal spinning jar is by the 5 independent transmissions of a motor.Here bearing 4, described in DE 19637270 A1, for example are designed to the permanent magnet bearing.

Whole spinning housing 2 can be by simple expression among the figure a transmission mechanism 6 move in vertical direction.

Rotary spinner 1 also has the yarn-guide tube 7 that can enter centrifugal spinning jar 3, and this pipe is to carry out oscillatory type by a transmission mechanism 8 to move.On the top of yarn-guide tube 7, a rewinding bobbin 9 is fixed in the bobbin holder 21.Bobbin holder 21 has a brake apparatus 10, be used for a rewinding bobbin when normal spinning process, to be fixed in resting position 11, and when back yarn rewinding process as shown in Figure 1, be fixed in rewinding position 12.

In addition, this tophan box spinning apparatus 1 most cases is a yarn breakage sensing device to be arranged, for example a kind of photoelectron sensing device.

The following examples, the yarn breakage monitoring is by photoelectron sensing device 13,13 ＇, monitors the sliver that rotates in the spinning process.

For guiding back yarn rewinding process behind yarn breakage, also be provided with one and be parallel to centrifugal spinning jar inwall 26 by what sensing mechanism 23 drove, and by the yarn resolution element 14 of bearing supporting.Yarn resolution element 14 has the edge of a knife 16 that can be close proximity to the coiling cone 32 of yarn cake 15, and one is axially being crossed the guide profile 17 of the edge of a knife 16.

Yarn resolution element 14 also is equipped with a power receiving device 18, bears axial component 19.

The sensing device that can compare 20 also can be installed in bobbin holder 20 zones.This sensing device 20 that is designed to the moment of torsion receiving system affacts the moment of torsion 22 of rewinding bobbin 9 in the time of can collecting back yarn rewinding process.

More advantageous version, this yarn resolution element 14 for example shown in Figure 3 all amplifies in Fig. 4 and Fig. 5 and Fig. 6, and it has a matrix 40, utilizes bolt 41 or element roughly the same that the feed carrier 42 of bobbin shape is fixed on this matrix.This feed carrier 42 has a guide profile 43 at end face, and in its cylindrical outer wall 44 zones a clearance type opening 45 that is used to be bearing in rotating yarn separator 46 on the bearing is arranged.

On bobbin shape feed carrier 42, with a bolt 49 that the guide runner 50 that a top has groove is fixing at least from the inside.Rotating yarn separator 46 is in the almost gapless guide groove 51 that is bearing in guide runner 50.Here yarn separator 46 can rotate with limitation around bolt 47, and at end face one edge of a knife 48 is arranged, and the edge of a knife can be different section shape.The edge of a knife 48 is as shown in Figure 6 rectangle preferably.

The full swing distance of yarn separator 46 can accurately be regulated by block 52, and block itself is to calibrate by bolt 53,54.At this moment block 52 is corresponding with a backhaul contact-making surface 55 of yarn separator 46.

Version is preferably, and the yarn separator 46 that can be rotated around bolt 47 by the bearing supporting is to be subjected to elasticity to load.

For example yarn separator 46 can be pneumatic loading as shown in Figure 4, and perhaps electronic loading is as shown in Figure 5 swung.

Pneumatic pendulous device 61 shown in Fig. 4 has two compressed

air nozzles

56,57 in examples of implementation, they are connected with a negative pressure source 64 through

pneumatic pipeline

62,63.

Here use one 2/2 reversal valve 65, and the most handy throttling arrangement 66 is connected on the pneumatic pipeline 62, and pneumatic pipeline 63 has only one 2/2 reversal valve 67.

Electrodynamic deflection device 35 shown in Fig. 5 has two solenoids that can switch on accurately 36,37 in examples of implementation, they are by electric wire 38,38 ＇, 38 ", 38 be connected to one not the expression power supply on." and 38 are through controllable electric switch 60, for example so-called normally opened contact and power line connection for the example here, electric wire 38.

In addition, mode is preferably, electric wire 38 " has a potentiometer 39 at least, accurately regulates the current strength that solenoid 37 is worked and accurately regulate the pressure that yarn separator 46 clings to the foot coiling layer of yarn cake 25 with it.

According to Fig. 3 to Fig. 5 the running of device is described as follows:

An one ribbon that comes out from (not illustrating on the figure) bar tube, perhaps a rove 27 under rove bobbin (also not drawing the figure) unwinding is input to the ribbon drafting system that is installed on centrifugal spinning jar 3 tops as shown in Figure 3, for example a drafting system 24.

The spun yarn 25 that forms under centrifugal spinning jar 3 effect of rotation enters into centrifugal spinning jar 3 by yarn-guide tube 7, and at the inwall coiling resultant yarn cake 15 of tophan box 3.In these cases, formed this layer is earlier from the upper area of centrifugal spinning jar 3, and yarn-guide tube 7 is to move as oscillatory type by transmission mechanism 8.Simultaneously, spinning housing 2 is by the continuous rising of transmission mechanism 6.Therefore spun yarn 25 is wound up on the tophan box inwall 26 of spinning tophan box 3 by so-called cop mode.

That come out from yarn guiding port and rotating sliver is subjected to a sensing device monitoring as shown in fig. 1 always during forming yarn cake 15.

Here preferred photoelectron sensing device is to be connected with a control device 30 by a signal line.

When yarn breakage occurring, it is collected because of lacking sliver by sensing device immediately, and signal notice sensing device 30, the latter makes rove bar automatic stop arrangement (not indicating on the figure) the generation effect in drafting system 24 zones immediately, stops the output of rove 27.In addition, control device 30 starts the brake apparatus 10 that is positioned on the bobbin holder 21 by signal line 34, makes rewinding bobbin 9 slide into rewinding position 12 from its resting position 11.

Then, yarn separator 14 according to the present invention enters in the centrifugal spinning jar 3 by transmission mechanism 23.

Band is positioned at the yarn resolution element 14 of the yarn separator 46 of resting position II, and with paralleling enter into tophan box 3 in, and be positioned shown in Figure 5 position with spinning tophan box inwall 26 this moment.

46 of yarn separators deflect into the operating position I shown in Fig. 3 and Fig. 4 by the resting position II shown in Fig. 5, and its edge of a knife 48 are clinged to modestly the foot coiling layer of yarn cake 15.

In other words, the yarn separator can perhaps use an electronic tumbler 35 inwardly to swing by the tumbler 61 of an air-operated control.

When the edge of a knife 48 of yarn separator 46 abutted foot coiling layer, this edge of a knife promptly was braked, and beginning rewinding process.Be positioned at the darker coiling layer in bottom at this moment by feed carrier 42, clapped like this by guide profile 43 especially, twined by yarn to prevent yarn resolution element 14 reliably.

If pneumatic actuator 61 is equipped with two

compressed air nozzles

56,57, then 2/2 reversal valve 65 is connected passage by control device 30 as shown in Figure 4, and compressed air stream 59 promptly comes out from compressed air nozzle 56.The stress level of this compressed air stream can use a throttling arrangement 66 accurately to regulate.Compressed air is run into the blocking surface 58 that is installed on yarn separator 46 back sides, makes yarn separator 46 deflect into operating position I as shown in Figure 4.The edge of a knife 48 of yarn separator 46 nestles up the foot coiling layer of yarn cake 15 on this operating position I, thereby enters aforesaid back yarn rewinding process.

Yarn separator 46 resets to the resting position II, can be by second compressed air nozzle 57, or finish by (not drawing on a figure) spring element, this spring substitutes being installed in this zone of second compressed air nozzle.If two compressed air nozzles are installed, then the getting type of

reversal valve

65,67 is, allow compressed air nozzle 56 keep closing, and reversal valve starts compressed air nozzle 57.

As when using a kind of electrodynamic deflection device, for example a kind of electric wire 38 that is connected to " electric switch 60, control by control device 30 by " connections " direction, electromagnetism electricity circle 37 is switched on.At this moment the electromagnetic current of Chan Shenging affacts to the yarn separator 46 of small part usefulness ferromagnetic material by " attractions ", and makes it deflect into as shown in Figure 3 and Figure 4 operating position I.

" at this moment the potentiometer 39 that is connected can clearly regulate effective magnetic force, thereby uses electronic arrangement for deflecting 35 can guarantee the edge of a knife 48 careful being loaded on the yarn cake 15 of yarn separator 46 with power line 38.

Here yarn separator 46 is returned to the resting position II, also can finish by (not drawing on a figure) spring element or by second solenoid 36 as pneumatic arrangement for deflecting.

Only otherwise leave general thinking of the present invention, other electric actuator can certainly substitute above-mentioned solenoid transmission.For example the inside rotation of yarn separator can also realize by a bimetallic transmission device or similar device.
