Tenth aspect present invention is, on the basis of first aspect, so selects the length of yarn package, and promptly it coordinates the available inner length in the centrifugal spinning part, wherein, shortened the Len req of recoiling bobbin simultaneously as far as possible.
The present invention the tenth is on the one hand, on the basis aspect the tenth, forms a yarn package, and the inner length that its maximum length equals the centrifugal spinning part deducts two distolateral safe distances.
The present invention the 12 aspect is that on the basis of the tenth one side, the length of distolateral safe distance is 5 millimeters.
The present invention the 13 aspect is, on the tenth on the one hand basis, uses such one to recoil bobbin, and promptly its length adds by the maximum length of yarn package that two distolateral free bobbins are brought in and obtains.
The present invention the 14 aspect is that on the basis of first aspect, the reaction time of the sensor of the reciprocating motion speed of yarn-guide tube, detection broken yarn and the pause of recoiling bobbin are apart from coordinating mutually.Here, method of the present invention especially has the following advantages, promptly avoided reliably especially stopping yarn fiber because of carelessness and starting a recoil process thus uncontrollably after the broken yarn in spinning process, this be because, Qi Dong recoil process causes disabled cop at least uncontrollably, even causes centrifugal spinning apparatus impaired.In addition, the yarn package that is wound on the recoil bobbin is irrespectively always being recoiled the position that is in a regulation on the bobbin with the moment that begins the process of recoiling, and this is very favorable with regard to continuing the processing tube yarn subsequently in the arrangement station of cross winding bobbin automatic winder especially.
In addition, in favourable form of implementation, as described in second aspect present invention, recoil bobbin and descend with feed speed in order to start a recoil process, this feed speed is coordinated with the vertical withdrawal speed that is the yarn that the yarn pie piles up.In other words, this recoils the vertical withdrawal speed of the feed speed of bobbin greater than this yarn.Just guaranteed that so the yarn cake can be wound up into to unwinding in the operation subsequently on the recoil bobbin again fully.
Here, the vertical withdrawal speed of yarn can be controlled by the reciprocating motion of yarn-guide tube according to different modes.
For example, preferably stipulated among the described embodiment at one as third aspect present invention, yarn-guide tube moves into and recoils the position is to carry out with such reciprocating motion speed, and promptly this reciprocating motion speed is starkly lower than the reciprocating motion speed of the yarn-guide tube in normal spinning process.Ground relevant with the fast feed of the recoil bobbin that is occurred has guaranteed thus that yarn package is being winding to from the beginning regularly to recoil on the bobbin after normal spinning process finishes when reaching predetermined yarn volume.
Described in aspect the present invention the 4th, the 5th by correspondingly making replacement feasible pattern that yarn-guide tube move into to recoil the vertical withdrawal speed that the position influences yarn.
For example according to fourth aspect present invention, yarn-guide tube moves into the recoil position with " normally " reciprocating motion speed and rests on slightly on this position subsequently.In other words, recoil the feeding delayed start of bobbin.
The feeding that bobbin is recoiled in delayed start has also provided in the described embodiment of fifth aspect present invention.Here, yarn-guide tube also at first moves into " normally " reciprocating motion speed and recoils the position, but carries out of short duration several times reciprocating stroke in this zone.Here, these of short duration reciprocating strokes pile up the generation positive role to yarn, in other words, and the thread layers of piling up unwinding well.
In addition, in advantageous embodiments, stipulated, recoil bobbin and moved the stretch journey when recoiling the position moving into, this section distance comprises the height of the coiling conical surface of yarn package, the pause distance of recoiling bobbin and the length of not having the recoil bobbin end of coiling yarn as described in the sixth aspect present invention.
As described in seventh aspect present invention, recoil bobbin and advantageously approximate 50 millimeters for this section distance that begins recoil process process.As mentioned above, these 50 millimeters is to be drawn by the pause height of the coiling conical surface of distance, yarn package and the length of the idle bobbin end that is not wound with yarn of the what is called of recoiling bobbin.In other words, under the situation of about 50 millimeters bobbin stroke, not only can obtain the fixed recoil bobbin enough big safe distance of yarn pin in relative rotation, and guarantee idle bobbin end, thereby in operation subsequently, operate cop all the time easily.The cop of Gou Chenging can not only be operated by interior yarn clamping head like this, and can operate by outer yarn clamping head.Guaranteed that also yarn package can be winding in good condition to be recoiled on the bobbin, thereby under the situation of the inner length that maximally utilises the centrifugal spinning part, can shorten the length of bobbin of recoiling bobbin as far as possible.
As described in eighth aspect present invention, the initial position of bobbin feeding to start with, always from the lower limb of the coiling conical surface of yarn package, it is fixed that this lower limb is come by the dead point, below of reciprocating motion stroke.So just guaranteed that yarn package has nothing to do with coiling conical surface shape or has nothing to do also with the moment that begins the process of recoiling thereby irrespectively always is on the same position with the size that is stacked on the yarn package in the centrifugal spinning part on the recoil bobbin after being wound up on the recoil bobbin.In other words, always constant at the lower limb of recoiling bobbin and the distance of recoiling between the incidental looping starting point on the bobbin, and for example, as mentioned above and as described in the ninth aspect present invention, preferably approximate 15 millimeters.
As described in the present invention the tenth to the 13 aspect, the length of yarn package is selected like this, and promptly the available inner length of centrifugal spinning part can obtain optimum utilization, and wherein, the length of recoiling bobbin is shortened as far as possible.So, centrifugal spinning apparatus is by the small and exquisite construction unit of integrally constructed compact conformation.In addition, to be deducted by the available inner length of centrifugal spinning part for example be that the twice of 5 millimeters distolateral safe distance obtains to the maximum length of yarn package.
In addition, this safe distance has guaranteed that at first the yarn cake is stacked on the inwall of centrifugal spinning part reliably.The minimum length of recoiling bobbin correspondingly adds that by the maximum length of yarn package the bobbin end length that is not wound with yarn of two free time obtains.
In addition, in order when broken yarn occurring, to avoid yarn-guide tube or to recoil bobbin and catch yarn fiber and may uncontrollably start a recoil process simultaneously, as described in the present invention the 14 aspect, the reciprocating motion speed of yarn-guide tube was coordinated mutually with the reaction time of the sensor that detects broken yarn.In other words, it is fixed that the reaction time of sensor must come like this, will guarantee promptly that when broken yarn yarn-guide tube finished once towards the reciprocating motion of recoiling the position, and the lower end of recoiling bobbin subsequently arrives the broken yarn district.

The specific embodiment
Fig. 1 schematically illustrates first embodiment of a centrifugal spinning apparatus 1, and it for example can be advantageously used in the method for the present invention of carrying out.
Here, centrifugal spinning apparatus 1 has a centrifugal spinning part 3 that becomes so-called centrifugal spinning jar form.
The centrifugal spinning part 3 of 2 li rotations of spinning cover be supported in the bearing 4 and by an electromagnetic drive mechanism 5 by the separate unit motor-driven.In illustrated embodiment, bearing 4 is configured to the magnetic bearing and the form of permanent magnet bearing preferably.
As shown in Figure 1, the neck of centrifugal spinning jar is reciprocating and can pass by downward axially movable yarn-guide tube 7 simultaneously by one.The yarn-guide tube 7 that can move into 3 li of centrifugal spinning parts links to each other with a driving mechanism that only schematically illustrates in these figure 8 for this reason.Yarn-guide tube 7 is carried out reciprocating motion strokes 30, in other words, and yarn-guide tube 7 reciprocating motion and moving axially simultaneously between upper and lower dead point 24A, 24B always.On yarn-guide tube 7, support one movably and recoiling bobbin 9, this recoil bobbin for example is connected with a hollow piston bar around pneumatic linear actuator 10 yarn-guide tube 7 and that can control in accordance with regulations.Recoil bobbin 9 is fixed on the resting position 33 by pneumatic linear actuator 10 and yarn-guide tube 7 in normal spinning process relevantly and can moves into one recoils position 34, so that starting recoil process, this will be described afterwards in detail.
But, replace the centrifugal spinning jar, centrifugal spinning apparatus 1 also can have a tubulose centrifugal spinning part 3 shown in Fig. 2 A, 2B and Fig. 3 A, 3B.Such embodiment also has a yarn-guide tube 7, and it enters 3 li of tubulose centrifugal spinning parts from the top.On yarn-guide tube 7, such as everyone knows, be mounted with one movably and recoil bobbin 9.Recoil bobbin 9 is in its resting position 33 ground here and is positioned on the yarn-guide tube 7, thereby the mouth 12 of recoiling the lower limb 11 relative yarn-guide tubes 7 of bobbin 9 bounces back slightly.The spacing that is called as bobbin pause distance 21 below this preferably is about 5 millimeters.
In addition, two of centrifugal spinning apparatus 1 embodiment have the yarn that a sensor 13 that is used to survey broken yarn or 13A and is used to start outside winding process and open the portion 14 that looses. Sensor 13 or 13A are connected by the intrinsic controller 19 of a signal line 20 or 20A and yarning position separately.According to the difference of embodiment, sensor 13 or be placed in the below of drafting system 6 and the infed material 18 of monitoring operation, or sensor 13A is placed in the following of centrifugal spinning part 3 and thereby the operation of the yarn pin 28 that rotates of monitoring shown in dotted linely.Under these circumstances, sensor 13A for example becomes optical scanner's form.
In addition, be provided with a yarn that is used for externally starting a winding process and open the portion 14 that looses.Yarn is opened the portion 14 that looses and is for example come into operation and have a driving mechanism 23 having no progeny behind the broken yarn in the spinning process or in the package in the recoil process, and this driving mechanism can realize that yarn opens the portion 14 that looses and be parallel to centrifugal spinning part inwall 25 ground and move.In addition, yarn is opened the portion 14 that looses and is had a blade 16 and the guide profile portion 17 that is embedded in blade 16 tops in the axial direction on the coiling conical surface 22 that is adjustable to yarn package 15.
Above centrifugal spinning part 3, be respectively equipped with a fiber skein drafting system such as drafting system 6.Or from (unshowned) bar tube, give drafting system 6 delivery of fibers strips, or be drafting system 6 supply rove from (also unshowned) rove bobbin.Preferably be introduced into the inside of centrifugal spinning part 3 this moment by sensor 13 and yarn-guide tube 7 through the infed material 18 of corresponding drawing-off, here, it also obtains twisting simultaneously on the inwall 25 of the centrifugal spinning part 3 that is attached to rotation under the situation that forms the yarn pin 28 that rotates.
The yarn that forms owing to twisting is positioned to by yarn-guide tube 7 on the inwall 25 of centrifugal spinning part 3, and promptly so-called yarn cake 15 yarn package of stipulating appearred, in the result.Originate in the process of the yarn package 15 in 26 zones, centrifugal spinning part 3 bottom surfaces in acquisition, yarn-guide tube 7 moves by driving mechanism 8 up-down vibration.Simultaneously, yarn-guide tube 7 falls to centrifugal opening 27 continuously by driving mechanism 8.The yarn that is spun into is stacked on the inwall 25 of centrifugal spinning part 3 according to the form of so-called incidental looping thus.If yarn package 15 has reached predetermined size,,, start a retension job according to following method then according to the present invention if broken yarn perhaps in spinning process, occurs:
When normal spinning finished, the method shown in Fig. 2 A-2E finished, and during the broken yarn in spinning process, the method shown in Fig. 3 A-3E begins to reinstate.
When normal spinning finishes, last thread layers of yarn package 15 always is stacked up like this, the top dead-centre 24B of to be yarn-guide tube 7 from the position in lower limb 29 zones of the coiling conical surface 22 of yarn package 15 shown in Fig. 2 A shift to reciprocating motion stroke 30, this position is identical with the last bottom dead centre 24A of reciprocating motion stroke 30.In addition, the last upwards reciprocating motion 32 in conjunction with the yarn-guide tube shown in distance/time diagram 7 preferably has a reciprocating motion speed that is starkly lower than yarn-guide tube 7 reciprocating motion speed common when " normally " spins in Fig. 4 A.In case yarn-guide tube 7 has arrived top dead-centre 24B, this top dead-centre equals to recoil position 31 in this case, then begins the recoil process.In other words, be moved into its recoil position 34 at the recoil bobbin 9 that is fixed on the yarn-guide tube 7 on the resting position 33 by correspondingly controlling pneumatic linear actuator 10.In bobbin stroke more fast, the lower limb 11 of recoiling bobbin 9 at first skims over the bobbin district 21 of pausing, and shifts out and arrive behind the height through the coiling conical surface 22 of yarn package 15 zone of the following free bobbin end 35 of recoiling bobbin 9 subsequently by 7 mouthful 12 of yarn-guide tube.Recoil bobbin 9 and catch the yarn pin 28 of living to rotate with its lower limb 11 in this action, this has triggered the recoil process.In other words, with one go up safe distance 39 and following safe distance 39A be stacked on yarn cake 15 on centrifugal spinning part 3 inwalls 25 shown in Fig. 2 C, 2D by around to recoiling on the bobbin 9, wherein, winding process always finishes in the zone of the mobile coiling conical surface 22 up.Because first winding layer is earlier towards free bobbin end 35 unwindings, so the feed speed of the recoil bobbin 9 in the coiling conical surface 22 zones must be greater than the over-end withdrawal speed of yarn this moment.
Be winding to fully at yarn package 15 and recoil on the bobbin 9 and after forming a cop 36 thus, cop 36 is shifted to a backstop 37 that limits cop 36 doff positions by moving axially of yarn-guide tube 7, shown in Fig. 2 E.Cop 36 is continued to be sent to the weaving loom that is connected on the (not shown) of back in process of production, preferably a bobbin winder by a conveying mechanism 38 shown in Fig. 2 E signal subsequently.
When broken yarn occurring in spinning process, method of the present invention similarly finishes, and this has illustrated in Fig. 3 A-3E.
Subsequently, making recoil bobbin 9 move into it by pneumatic linear actuator 10 recoils position 34 and makes yarn open diffusing portion 14 from 3 li of below immigration centrifugal spinning parts, shown in Fig. 3 C.In case yarn is opened the blade 16 of the portion 14 that looses and touched yarn cake 15 on the inwall 25 that is stacked on centrifugal spinning part 3, then the yarn cake is because the rotation of centrifugal spinning part 3 is winding to recoils on the bobbin 9.Open guide profile portion in the portion 14 that looses at yarn and prevent that yarn from opening the portion 14 that looses and also being reeled absent-mindedly 17 this moments.
Open after the portion that looses removes for 14 times at yarn, cop 36 moves into the doff position by making yarn-guide tube 7 shift to a backstop 37 shown in Fig. 3 E, and on this position, cop 36 to be connect away by a conveying mechanism 38 and can be seen off in order continuing to process.
The present invention is not limited to the foregoing description.In the scope of overall conception of the present invention, can consider various other variant embodiment.
For example, can when normal spinning finishes, also make yarn-guide tube 7 enter top dead-centre 31 fully, stop reciprocating motion subsequently and wait recoiling bobbin 9 and entering and recoil position 34, such shown in Fig. 4 C with " normally " reciprocating motion speed.
Another flexible program regulation drafting shown in Fig. 4 B, the last upwards reciprocating motion 32 of yarn-guide tube 7 carry out with the reciprocating motion speed of " normally " and then also finish of short duration several times reciprocating stroke 40 subsequently in top dead-centre 31 zones.
