Each the silk thread Y that is directed into up-coiler 30 is traversed along left and right directions (axis direction of bobbin support shaft 32) by traversing gear 33, is wound up on the bobbin 31 of rotation.And, be wound up into silk thread Y on the bobbin 31 forms drum on this bobbin 31 package 34.
So, take-up winding facility 100 constitutes multi-filament line Y (multifilament threads) by spinning many filament F and tying up, by each silk thread Y being stretched and heat setting can be made the silk thread Y with desirable characteristic.And take-up winding facility 100 makes the equipment of package 34 for the silk thread Y that produces by such coiling.
It more than is the overall structure of the take-up winding facility 100 of the present invention's first example.For the superiority of the quality of narrating the silk thread Y that makes with this take-up winding facility 100, the problem points of the take-up winding facility 200 of prior art is described with Fig. 2 below.But, add identical Reference numeral for the structure identical with above-mentioned take-up winding facility 100, be that the center describes with different parts.And the arrow shown in the figure is represented the throughput direction of filament F and silk thread Y.
Fig. 2 is the integrally-built front view of the take-up winding facility 200 of expression prior art.Take-up winding facility 200 mainly by the spinning machine 10 that spins filament F, pre-warmed the 1st Nelson roller of tying up the silk thread Y that filament F forms to 40, carry out from the 1st Nelson roller send 40 and the 2nd Nelson roller of the heat setting of the silk thread Y that stretches to 50 and will constitute the up-coiler 30 that the 50 silk thread Y that send are wound up on the bobbin 31 from the 2nd Nelson roller.
The 1st Nelson roller rises to the temperature of this silk thread Y to be fit to the pre-warmed device of the temperature that stretches-promptly carry out to 40 for tie up multi-filament line Y that filament F forms in order to stretch respectively.The 1st Nelson roller to 40 for constituting the pair of rolls unit (with reference to Fig. 4 (A), Fig. 4 (B)) that the 1st Nelson roller is not parallel mutually to the rotating shaft of 40 2 roller 40a, 40b, have predetermined inclination alpha rotation.And, constitute the 1st Nelson roller to each roller 40a, 40b of 40 owing to be the pre-warmed roller that carries out silk thread Y, therefore its surface temperature is maintained pre-warmed target temperature.
As shown in Figure 3A, be directed into the 1st Nelson roller to the silk thread Y continuous several times on 40 be erected at for the temperature that makes this silk thread Y be pre-warmed target temperature and heated each roller 40a, 40b twine lastly.At this moment, each roller 40a, 40b each other rotating shaft as mentioned above have predetermined inclination alpha ground rotation, and therefore the silk every winding in road of the silk thread Y that twines is once moved down to the axis direction of this roller 40a, 40b.
Therefore, constitute under the situation that the 1st Nelson roller twines on to each roller 40a, 40b of 40 even be erected in silk thread Y continuous several times, because every winding once moves down in a silk road, so the result can avoid silk thread Y interference each other.
The 2nd Nelson roller is the temperature that makes the silk thread Y that the is stretched heat treatment carry out this silk thread Y-promptly the carry out device of heat setting that rises to 50.The 2nd Nelson roller to 50 for constitute the 2nd Nelson roller not parallel mutually to the rotating shaft of 50 2 roller 50a, 50b, the same have a pair of rolls unit that predetermined inclination alpha is rotated with the 1st Nelson roller to 40.And, constitute the 2nd Nelson roller to each roller 50a, 50b of 50 owing to be the roller that carries out the heat setting of silk thread Y, therefore its surface temperature is maintained the target temperature of heat setting.
Shown in Fig. 3 B, be directed into the 2nd Nelson roller to 50 silk thread Y be erected at for many times for the temperature that makes this silk thread Y be the target temperature of heat setting and heated each roller 50a, 50b twine lastly.At this moment, the mutual as mentioned above rotating shaft of each roller 50a, 50b has predetermined inclination alpha ground rotation, and therefore the silk every winding in road of the silk thread Y that twines is once moved down to the axis direction of this roller 50a, 50b.
Therefore, constitute under the situation that the 2nd Nelson roller twines on to each roller 50a, 50b of 50 even be erected at for many times at silk thread Y, because every winding once moves down in a silk road, so the result can avoid silk thread Y interference each other.
But, constitute, with the having predetermined inclination alpha rotation not parallel mutually owing to its rotating shaft of the 1st Nelson roller to each roller 40a, 40b of 40, therefore be erected to produce sometimes on the silk thread Y on this roller 40a, the 40b and vibrate.And, constitute the 2nd Nelson roller to each roller 50a, 50b of 50 also since its rotating shaft not parallel mutually, have predetermined inclination alpha ground rotation, therefore the silk thread Y that is erected on this roller 50a, the 50b produces vibration sometimes.
This situation is increasing from spinning machine 10 spun filament F, is increasing under the situation of radical of the silk thread Y that makes and obviously occur.Be in detail, being erected at the 1st Nelson roller in reply increases the radical of the silk thread Y on 40 (the 2nd Nelson roller is to 50), and the inclination alpha of the rotating shaft by increasing each roller 40a, 40b (each roller 50a, 50b) is avoided under the situation that silk thread Y interferes with each other and often being taken place.
Here, use Fig. 4 B to be described in detail in to have increased the vibration that constitutes the silk thread Y that produces under the situation of the 1st Nelson roller to the inclination alpha of the rotating shaft of 40 each roller 40a, 40b.In addition, to 50,, therefore omit explanation for the 2nd Nelson roller owing to the same to 40 with the 1st Nelson roller.
Fig. 4 B is erected at the perspective view of the 1st Nelson roller to the vibrative state of silk thread Y on 40 for expression.In addition, in order to simplify one that has only represented among the multi-filament line Y.And the arrow shown in the figure is represented the throughput direction of silk thread Y.
Be directed into the 1st Nelson roller to the silk thread Y on 40 at first hang up constitute the 1st Nelson roller to a roller 40a of 40 on and be sent by the rotation of this roller 40a.And, the silk thread Y that is sent by this roller 40a hang up constitute the 1st Nelson roller to another roller 40b of 40 on.Then, the silk thread Y that is sent by the rotation of roller 40b is hanged up once more on roller 40a, repeatedly carries out such hanging up repeatedly.
So, repeatedly be erected at the 1st Nelson roller the silk thread Y that each roller 40a, 40b of 40 twine is once moved down in a silk road by every winding lastly, can avoid silk thread Y interference each other.But, X1, X2, X3 in the drawings ... owing to the unstability of the frictional force between silk thread Y and each roller 40a, the 40b, produce vibration on the silk thread Y that sets up sometimes on the point.
The X2 point specifically describes among the figure if be conceived to, and the silk thread Y of ordering at X2a is stably being kept by the high frictional force with roller 40b.But, being accompanied by the rotation of roller 40b, frictional force reduces down gradually when near the X2b point.And, when by the X2b point when the X2c point, the frictional force of silk thread Y and roller 40b sharply reduces, and becomes 0 at the X2c point.That is, silk thread Y is sent from roller 40b at the X2c point.
And, because roller 40a has predetermined inclination alpha ground rotation with respect to the rotating shaft of roller 40b, therefore because the turning effort of roller 40a makes generation angle of bend β on the silk road that X2c order at the tension force on the silk thread Y.So, the frictional force between this silk thread Y and roller 40b on the silk thread Y at the X2b point to sharply reduce between the X2c point, also acted on the tension force that comes from angle of bend β direction, just produced the vibration that the skew suddenly of silk road causes.
So, because the 1st Nelson roller has predetermined inclination alpha ground rotation to each roller 40a, 40b of 40, therefore be erected at the silk thread Y that this roller 40a, 40b twine lastly and produce vibration sometimes.Especially under the situation of the radical that increases the silk thread Y that makes from spinning machine 10 spun filament F, increase, because necessity of the inclination alpha of setting each roller 40a, 40b is arranged biglyyer, therefore vibration significantly produces, and will interfere with each other because of the silk thread Y that goes forward side by side sometimes causes the decline of silk thread quality.
And, twine owing to repeatedly being erected at the 1st Nelson roller each roller 40a, 40b 40 lastly, therefore necessity of the roll shaft length that increases this roller 40a, 40b arranged.For example, the width of hanging up of supposing to hang up the multi-filament line Y on roller 21 is B, and under the situation of three windings, the roll shaft length of supposing this roller 21 is L, and then L ≈ 3B is necessary at least.And in order to ensure the contact length of silk thread Y and each roller 40a, 40b, the temperature efficiency of this silk thread Y is risen well, the roller diameter that increases this roller 40a, 40b also is necessary.Therefore, the 1st Nelson roller to each roller 40a, 40b of 40 because roll shaft length is elongated and roller diameter becomes big, therefore along with abnormal vibrations will be resonated, be produced to the rotation of this roller 40a, 40b sometimes.
And the 1st Nelson roller because roll shaft length is long and roller diameter is big, therefore also exists surface temperature be difficult to become fixing, the unstable such problem of silk thread quality and the cost of each roller 40a, 40b to increase such problem to each roller 40a, 40b of 40.
More than for increasing in the take-up winding facility 200 of prior art from spinning machine 10 spun filament F, the problem that exists when increasing the radical of the silk thread Y that makes.Describe the take-up winding facility 100 of the present invention's first example below in detail.
Fig. 5 is the front view of feeding roll dies group 20 of the take-up winding facility 100 of this example of expression.And arrow shown in the figure is represented the throughput direction of silk thread Y.
As mentioned above, this example feeds roll dies group 20 for possessing a plurality of hang up multi-filament line Y and rotations, the device of the roller 21 by sending these multi-filament lines Y like this.In addition, constitute the motor 22 driving rotations that each roller 21 of feeding roll dies group 20 is used as the peripheral speed regulon, the peripheral speed that can regulate each roller 21 arbitrarily.
And roll dies group 20 employings of feeding of this example constitute the rotating shaft parallel rollers group 20P parallel to each other that this feeds all rollers 21 of roll dies group 20.And, feed roll dies group 20---the roller 21 that promptly constitutes parallel rollers group 20P is divided into pre-warmed warm-up mill group 20H that carries out silk thread Y and the modified roller group 20T that carries out the heat setting of silk thread Y.
In this example, have 10 rollers 21 that constitute warm-up mill group 20H in higher level's side of feeding roll dies group 20, have 9 rollers 21 that constitute modified roller group 20T in subordinate's side.But the number and the configuration of roller 21 are not limited thereto, and also can be for example dispose the structure of modified roller group 20T at the side configuration warm-up mill group 20H of subordinate, in higher level's side.In addition, be built-in with electrothermal heater 23 in each roller 21 of formation warm-up mill group 20H and modified roller group 20T, the surface temperature that can regulate this roller 21 arbitrarily as thermostat unit.
Wherein, for each roller 21 that constitutes warm-up mill group 20H, by in the silk road of silk thread Y from upstream side downstream the order of side be defined as roller 21Ha, roller 21Hb, roller 21Hc, roller 21Hd successively ...And, for each roller 21 that constitutes modified roller group 20T, by in the silk road of silk thread Y from upstream side downstream the order of side be defined as roller 21Ta, roller 21Tb, roller 21Tc, roller 21Td successively ...
Be directed into the silk thread Y that feeds roll dies group 20 and at first be heated the temperature that roller group 20H is heated to suitable stretching.The silk thread Y that promptly is directed into warm-up mill group 20H hangs up and is being set to each roller 21Ha, 21Hb, the 21Hc of predetermined surface temperature ... on send, by being heated to pre-warmed target temperature like this.
Then, the silk thread Y that is heated to pre-warmed target temperature is sent from warm-up mill group 20H and is directed to modified roller group 20T.At this moment, owing to constitute each roller 21Ta, 21Tb, the 21Tc of modified roller group 20T ... peripheral speed than each roller 21Ha, the 21Hb, the 21Hc that constitute warm-up mill group 20H ... the speed height, so silk thread Y is suitably stretched when modified roller group 20T goes from warm-up mill group 20H.
The silk thread Y that is directed into modified roller group 20T is heated to the temperature that is fit to heat setting by modified roller group 20T.That is, the silk thread Y that is directed into modified roller group 20T is hanged up and is being set at each roller 21Ta, 21Tb, the 21Tc of predetermined surface temperature ... on send, by being heated to the target temperature of heat setting like this.Then, the silk thread Y that heat setting is over sends from modified roller group 20T, is directed into up-coiler 30.
In addition, this example to feed among the roll dies group 20 all rotating shafts that constitute this roller 21 of feeding roll dies group 20 all parallel.That is, owing to be parallel rollers group 20P, it is right therefore not comprise the Nelson roller that for example has predetermined inclination and rotate.Therefore, the multi-filament line Y that hangs up on each roller 21 is not sent by this roller 21 with twining, in warm-up mill group 20H according to roller 21Ha, roller 21Hb, roller 21Hc, roller 21Hd ... order be sent, in modified roller group 20T according to roller 21Ta, roller 21Tb, roller 21Tc, roller 21Td ... order be sent.
That is, discardedly in the take-up winding facility 100 of this example make silk thread Y be erected at the Nelson roller to twine the structure that preheats with heat setting lastly.At least to constituting each roller 21 of parallel rollers group 20P, silk thread Y repeatedly is not wound on the specific roller 21, contacts with silk thread Y with the contact length shorter than the circumferential length of this roller 21.
By adopting such structure,,, therefore can suppress to be erected at the vibration of the silk thread Y on the roller 21 owing to do not use the Nelson roller right even under the situation of the radical that increases the silk thread Y that makes from spinning machine 10 spun filament F, increase.Thus, the generation that silk thread Y is interfering with each other and thickness of yarn saves can be prevented, the quality of the silk thread Y of manufacturing can be improved.
And, even have respectively under the right situation of Nelson roller with each roller 21 that constitutes parallel rollers group 20P, since be not only with this Nelson roller to preheating the structure with heat setting, so can reduce the winding number of times of silk thread Y, can suppress the vibration of this Nelson roller centering silk thread Y.Thus, the generation that silk thread Y is interfering with each other and thickness of yarn saves can be prevented, the quality of the silk thread Y of manufacturing can be improved.
And the roll dies group 20 that feeds of this example does not use the Nelson roller to preheating and heat setting, even have the winding number of times that also can reduce silk thread Y under the right situation of Nelson roller, the roll shaft that therefore can shorten roller 21 is long.For example, the width of hanging up of supposing to hang up the multi-filament line Y on roller 21 is B, supposes that the roll shaft of this roller 21 is long for L, can make L ≈ B (with reference to Fig. 6).And, by each roller 21 of intensive configuration formation warm-up mill group 20H and modified roller group 20T, can the temperature of silk thread Y be risen efficient, therefore can reduce the roller diameter of roller 21.Thus, constitute each roller 21 of feeding roll dies group 20 and can accompanying rotation not produce resonance, therefore can avoid abnormal vibrations.
In addition, because each roller 21 of formation hello roll dies group 20 can make roll shaft length shorten and can reduce roller diameter, therefore the surface temperature of this roller 21 can be maintained fixingly, can improve the quality of the silk thread Y of manufacturing by the heat setting of the silk thread Y that stably carries out the stretching of silk thread Y and be stretched.And, shorten and roller diameter is reduced by the roll shaft length that can make roller 21, can also suppress the cost of this roller 21.
And, because setting its surface temperature respectively, each roller 21 of formation warm-up mill group 20H heats silk thread Y, therefore can precision make silk thread Y rise to pre-warmed target temperature well.And, because setting its surface temperature respectively, each roller 21 of the modified roller group 20T of formation heats silk thread Y, therefore can precision make silk thread Y rise to the target temperature of heat setting well.Thus, can carry out the stretching of silk thread Y well and the heat setting of the silk thread Y that has been stretched, can improve the quality of the silk thread Y of manufacturing.
And, because each roller 21 of formation warm-up mill group 20H is different with the surface temperature that each roller 21 that constitutes modified roller group 20T is just set, its structural form is the same, therefore the number of the roller 21 that constitutes warm-up mill group 20H and modified roller group 20T be can change by the list of modification surface temperature, ratio or change collocation perhaps changed.Thus, can change the form that preheat, can improve the quality of the silk thread Y of manufacturing according to the kind of silk thread Y with heat setting.
