Description
Technical field
The present invention relates to spinning machine, particularly is a kind of structure that spun yarn is applied tension force in this spinning machine.
Background technology
Existing spinning machine for example TOHKEMY 2004-124333 communique is described, and this spinning machine has usually: be rotated driving metal system delivery roll (delivery roller) and relative configuration with delivery roll and the rubber system mip rolls (nip roller) of driven rotation.The spun yarn that spinning machine is sent spinning apparatus utilizes delivery roll and mip rolls clamping to carry.That is, the rotation by delivery roll applies tension force to the yarn of drawing from spinning apparatus.By yarn being applied the tension force of regulation, can draw yarn from spinning apparatus with the speed of regulation, and with the speed of regulation with yarn downstream side carry.
But, when the spinning machine that adopts the record of TOHKEMY 2004-124333 communique spins, in order to ensure yarn quality must be as requested the yarn haul-off tension of numerical value during, clearing (yarn flaws detection) to the thickness (number) of yarn, spinning the time yarn tension etc. control exactly.That is,, then can cause harmful effect in spinning process to yarn quality if thickness of yarn or the haul-off tension of spinning during work fluctuate.In addition, if the tension force during clearing does not keep necessarily, then can't carry out clearing exactly.
Above-mentioned thickness of yarn is by the velocity ratio decision of delivery roll and back roller.Haul-off tension during above-mentioned spinning is by the velocity ratio decision of delivery roll and preliminary roller.In addition, under the situation with delivery roll and coiler device (Yarn relaxation eliminating device), the tension force during above-mentioned clearing is by the velocity ratio decision of delivery roll and Yarn relaxation eliminating device.Like this, the yarn transporting velocity of delivery roll is the important parameter that influences yarn quality.Therefore, need utilize delivery roll with speed delivered yarn accurately.
On the other hand, in the coiler device that the delivery roll downstream is possessed,, therefore always cause the fluctuation of yarn tension in the delivery roll downstream because yarn traverses (back and forth) on the package surface.Although the fluctuation of this tension force can be relaxed by device for adjusting tension of yarn to a certain extent, this tension fluctuation might be delivered to the delivery roll of this device for adjusting tension of yarn upstream side.At this moment, tension fluctuation is delivered to the problem of upstream side if delivery roll and mip rolls to the chucking power deficiency of yarn, then may cause yarn and roller to skid.Consequently, yarn quality reduces owing to delivery roll causes the fluctuation of yarn transporting velocity.In order to prevent such yarn transporting velocity fluctuation, preferred delivery roll and mip rolls are big and stable to the chucking power of yarn.
But, thisly utilize two rollers yarn to be carried out in the structure that clamping carries existing, be limited in order to the brute force of clamping yarn.Consequently, be difficult to obtain enough strong chucking power and avoid fully from the influence of the tension fluctuation in downstream.In addition, owing to reasons such as wearing and tearing that produce on rubber system mip rolls surface and parts assembly precisions, the uneven problem of above-mentioned chucking power can appear.Therefore, be difficult to make chucking power uniformity between a plurality of spinning units, thereby can't guarantee that the yarn quality of being produced stablizes constant.And chucking power reduces along with the rubber wearing and tearing on mip rolls surface, causes yarn to skid sometimes and takes place frequently.
The mip rolls that has adopts cantilever support formula structure for the ease of maintenance.But in this case, an end of mip rolls and the chucking power on the other end are adjusted into equalization in textural being difficult to.Therefore, for example traversing when yarn is swung by above-mentioned, chucking power fluctuates because of clip position changes, thereby causes yarn tension fluctuation the causing yarn clearer flase drop that takes place frequently.
Mip rolls needs periodic replacement as consumptive material because of the rubber surface wearing and tearing.The easy circumvolution flyings of delivery roll and mip rolls etc.Under the situation of delivery roll and mip rolls circumvolution flyings etc., need the operator to be removed.Like this, utilize the conveying of the yarn that delivery roll and mip rolls carry out, have the big problem of maintenance workload.

Thus, above-mentioned spinning machine can apply tension force and not influenced by other yarn transfer unit the spun yarn of sending from spinning apparatus by the yarn storing unit.In addition, between spinning apparatus and yarn storing unit, exist in the spinning machine of other yarn transfer unit, have the problem of these other yarn transfer unit circumvolution flyings.But, in above-mentioned spinning machine, can avoid this problem and improve maintainability.Therefore and above-mentioned spinning machine is compared with existing spinning machine can cut down amount of parts, can simplify the structure of spinning machine integral body and suppresses cost.
In above-mentioned spinning machine, it is high-wearing feature material (for example metal) that preferred above-mentioned yarn is deposited roller.
Thus, the yarn durability of depositing roller is compared with rubber system roller and is improved.Therefore, above-mentioned spinning machine is compared with existing spinning machine, can cut down the yarn quality of consumptive material quantity and stable for extended periods of time.And, in above-mentioned spinning machine, can suppress wearing and tearing to Effect on Performance, therefore with for example carry the existing structure of spun yarn to compare by rubber system roller, can suppress the yarn carrying capacity inequality between a plurality of spinning units in the spinning machine.That is, the yarn quality that these a plurality of spinning units are produced is identical between spinning unit.In addition, adopt easy rapidoprints such as metal, then be easy to make yarn and deposit roller with higher processing precision if yarn is deposited roller.Thereby can suppress the accessory size deviation between the spinning unit, be easy to realize the quality homogeneous control of output yarn between the spinning unit more.
In above-mentioned spinning machine, preferred above-mentioned yarn storing unit is a Yarn relaxation eliminating device, and above-mentioned Yarn relaxation eliminating device constitutes the yarn tension fluctuation that can absorb between this yarn storing unit and the above-mentioned coiler device.
Thus, the yarn tension fluctuation between Yarn relaxation eliminating device and the coiler device can not impact the yarn tension between Yarn relaxation eliminating device and the spinning apparatus.Consequently, can further improve yarn quality.And, because Yarn relaxation eliminating device has the dual-use function of carrying spun yarn and adjusting yarn tension concurrently, therefore carry and compare with the existing structure of parts with tension adjustment with parts with being respectively equipped with yarn, can cut down the amount of parts of spinning machine and suppress cost.
In above-mentioned spinning machine, preferred above-mentioned spun yarn is deposited at above-mentioned yarn on the periphery of roller and can be reeled more than at least 10 weeks on zero lap ground.

Above-mentioned coiler device 13 possesses winding drum (drum) 72 and traversing gear 75.Winding drum 72 and above-mentioned bobbin 48 or on bobbin 48 coiling spun yarn 10 and the outer peripheral face of the package 45 that forms contact and drive.Traversing gear 75 possess can with the involutory traverse guide (traverse guide) 76 of spun yarn 10.Utilize not shown drive unit to make to traverse guide rod 76 to move back and forth, utilize not shown Motor Drive winding drum 72 simultaneously, thereby make package 45 rotations that contact with winding drum 72, with spun yarn 10 cross windings.
Below, with reference to Fig. 3 the details of Yarn relaxation eliminating device 12 is described.The lax roller 21 eliminated is made by high-abrasive material, and is fixed in the arbor 25a of motor 25.The lax side with yarn guide member 22 of eliminating roller 21 is the top, and a side of configuration motor 25 is a cardinal extremity.The lax outer peripheral face 21a that eliminates roller 21 possesses base end side tapering 21b, cylindrical portion 21c, tip side tapering 21d according to the order from the cardinal extremity to the top.
The tip side of cylindrical portion 21c is slightly thin shape.Cylindrical portion 21c is the shape that is connected smoothly with the tapering 21b and the 21d of both sides.In order to carry spun yarn 10 by the lax enough power of roller 21 acquisitions of eliminating, preferred spun yarn 10 is reeled more than 10 weeks on zero lap ground on the outer peripheral face 21a that eliminates roller 21 that relaxes at least.Therefore, the size of cylindrical portion 21c forms and can deposit above spun yarn 10 of at least 10 weeks.Above-mentioned yarn amount of storage sensor 27 is set to relative with this cylindrical portion 21c.27 pairs of yarn amount of storage sensors are wound in the lax amount of storage of eliminating the yarn of roller 21 and detect, and send testing result to cell controller.
It is the mild taper of big footpath side that base end side tapering 21b and tip side tapering 21d form respectively with the end face side.On the outer peripheral face 21a of lax elimination roller 21, base end side tapering 21b makes the spun yarn 10 of supply from the cylindrical portion 21c of large-diameter portion branch in the middle of the path part moves to smooth-goingly, thereby spun yarn 10 fitly is wound in the surface of cylindrical portion 21c.Tip side tapering 21d has at spun yarn 10 and separates when relaxing from the lax roller 21 of eliminating, and can prevent the function of the so-called knocking over phenomenon of spun yarn 10 slippages of reeling.And tip side tapering 21d has can make spun yarn 10 divide conveying in order to carry out unwinding from the path part to the large-diameter portion of end face side, thereby guarantees the function that spun yarn 10 can be drawn smooth-goingly.
Any one party is equipped with permanent magnet in flyer shaft 33 or the lax elimination roller 21, and the opposing party then installs hysteresis material.Constitute the torque generation part by above-mentioned magnetic part, produce prevention yarn guide member 22 and carry out counterrotating torque with respect to the lax roller 21 of eliminating.
In above formation, Yarn relaxation eliminating device 12 makes flier 38 and spun yarn 10 hooks, and this yarn 10 is wound in the lax roller 21 of eliminating, thereby eliminates the lax of spun yarn 10 and can adjust winding tension.
Like this, coiling spun yarn 10 was then separated the spun yarn 10 that relaxes when Yarn relaxation eliminating device 12 reduced (spun yarn 10 is lax) at the tension force of spun yarn 10 when the tension force of spun yarn 10 increases.Thus, Yarn relaxation eliminating device 12 can be eliminated the lax of spun yarn 10 and provide suitable tension force to spun yarn 10.And as mentioned above, yarn guide member 22 can absorb the tension fluctuation on the spun yarn 10 between Yarn relaxation eliminating device 12 and the coiler device 13.Thus, can utilize Yarn relaxation eliminating device 12 to prevent that this tension fluctuation from impacting the spun yarn 10 between spinning apparatus 9 and the Yarn relaxation eliminating device 12.Consequently, can utilize Yarn relaxation eliminating device 12, spun yarn 10 be drawn from spinning apparatus 9 with more stable speed.
But, stably carry spun yarn 10 (drawing) in order to utilize above-mentioned lax elimination roller 21 from spinning apparatus 9, need remain spun yarn 10 at the lax a certain amount of state of reeling on the roller 21 of eliminating.Therefore, in the present embodiment, reel cage arm 71 is carried out FEEDBACK CONTROL according to signal from yarn amount of storage sensor 27.
At first, hang on the tension force on the spun yarn 10 (spun yarn 10 between Yarn relaxation eliminating device 12 and the coiler device 13) of yarn guide member 22, eliminate the speed (spinning the speed of yarn from spinning apparatus 9) of roller 21 delivered yarn and the winding speed decision of coiler device 13 by lax basically.That is, winding speed is greater than the yarn transporting velocity, and then the tension force on the spun yarn 10 increases, and separates the spun yarn 10 that relaxes gradually from the lax roller 21 of eliminating.Otherwise when winding speed during less than the yarn transporting velocity, the tension force that acts on spun yarn 10 reduces, at the lax spun yarn 10 of reeling gradually on the roller 21 of eliminating.Usually the lax rotating speed (yarn spins speed) of eliminating roller 21 is constant, and the tension force that therefore hangs on the spun yarn 10 of yarn guide member 22 mainly changes according to the winding speed of coiler device 13.In addition, send the speed of spun yarn 10, then by the rotating speed decision of the roller drive division 25 of above-mentioned rotating speed control part control from spinning apparatus 9.
Usually in order when reeling spun yarn 10 to be applied suitable winding tension, the speed setting of winding drum 72 is to make winding speed omit high than the lax speed (spinning apparatus 9 spins the speed of yarn) of eliminating roller 21 delivered yarn.Therefore separate yarn amount of storage minimizing when relaxing gradually when being wound in the lax spun yarn 10 of eliminating roller 21.
To detect the yarn amount of storage be that setting is when following (for example being wound in the lax spun yarn 10 of eliminating roller 21 peripheries is below 10 weeks) deposit sensor 27 by yarn, the not shown driving lift cylinders of cell controller control of this spinning unit 2 makes reel cage arm 71 rotate to Fig. 2 left side, makes package 45 leave winding drum 72.Thus, package 45 loses driving force, although also can continue the inertia rotation, its winding speed reduces gradually.
Consequently, by yarn guide member 22 spun yarn 10 of reeling gradually, can recover the lax yarn amount of storage of eliminating roller 21.But if the spun yarn 10 of reeling on the lax elimination roller 21 surpasses the amount of storage of allowing on the cylindrical portion 21c, then spun yarn 10 can be transferred to base end side tapering 21b in lax position of eliminating coiling on the roller 21 and reel in big footpath side.Consequently, can cause and to draw spun yarn 10 with speed accurately from spinning apparatus 9.Therefore, whether the amount of storage that need utilize yarn amount of storage sensor 27 to detect spun yarn 10 is more than the setting.If it is setting when above that yarn amount of storage sensor 27 detects the amount of storage of spun yarn 10, then the said units controller makes reel cage arm 71 rotate to Fig. 2 right side, and package 45 is contacted with winding drum 72.Thus, recover winding speed, thereby separate the spun yarn 10 that relaxes from the lax roller 21 of eliminating gradually as mentioned above.
Like this, utilize lift cylinders to make reel cage arm 71 swing and make package 45 with winding drum 72 contacts or separate, thereby can regulate the winding speed of coiler device 13.Utilize yarn amount of storage sensor 27 to detect the lax yarn amount of storage of eliminating roller 21, to cell controller detection feedback result the winding speed of coiler device 13 is controlled, thereby guaranteed to deposit a certain amount of above spun yarn 10 all the time on the lax elimination roller 21.
As mentioned above, the spinning frame 1 of present embodiment possesses spinning apparatus 9, coiler device 13, Yarn relaxation eliminating device 12.9 pairs of fibre bundles of spinning apparatus 8 are twisted and generation spun yarn 10.13 pairs of spun yarns of sending from spinning apparatus 9 10 of coiler device are reeled and are formed package 45.Yarn relaxation eliminating device 12 is configured between spinning apparatus 9 and the coiler device 13, and also deposits at the periphery coiling spun yarn 10 of the lax elimination roller 21 that rotates temporarily.Spinning frame 1 utilizes 12 pairs of spun yarns 10 of Yarn relaxation eliminating device to apply tension force and it is drawn from spinning apparatus 9.
That is, spinning frame 1 utilizes lax elimination roller 21 that periphery is wound with spun yarn 10 to provide tension force to spun yarn 10 fibre bundle 8 of twisting (particularly for).Therefore, spinning frame 1 is compared with the existing structure that for example the clamping spun yarn is carried between two relative rollers, and is bigger as the lax elimination roller 21 and the contact area between the spun yarn 10 of yarn transfer unit.Consequently can apply tension force to spun yarn 10 with enough carrying capacitys.Therefore, can in spinning frame 1, not relax to eliminate and skid between roller 21 and the spun yarn 10 etc., can spun yarn 10 be drawn from spinning apparatus 9 with stable speed.Spinning machine 1 can the uniform spun yarn 10 of production quality.
In the spinning frame 1 of present embodiment, the spun yarn 10 from spinning apparatus 9 is sent does not directly import Yarn relaxation eliminating device 12 via other yarn transfer unit.
Thus, spinning frame 1 can apply tension force and not influenced by other yarn transfer unit by 12 pairs of spun yarns of sending from spinning apparatus 9 10 of Yarn relaxation eliminating device.In addition, between spinning apparatus 9 and Yarn relaxation eliminating device 12, exist in the spinning frame of other yarn transfer unit, have the problem of these other yarn transfer unit circumvolution flyings.But spinning frame 1 can be avoided this problem and improve maintainability.And spinning frame 1 can be cut down amount of parts, simplifies the structure of spinning frame 1 integral body and suppresses cost.
In the spinning frame 1 of present embodiment, lax elimination roller 21 is ABRASION RESISTANCE materials.
Thus, the lax durability of eliminating roller 21 is compared with rubber system roller and is improved.Therefore, spinning frame 1 is compared with existing spinning frame, can cut down the yarn quality of consumptive material quantity and stable for extended periods of time.And, in spinning frame 1, can suppress wearing and tearing to Effect on Performance, therefore with for example carry the existing structure of spun yarn to compare by rubber system roller, can suppress the yarn carrying capacity inequality between a plurality of spinning units 2 in the spinning frame 1.Yarn quality between spinning unit 2 that these a plurality of spinning units 2 are produced is identical.
In the spinning frame 1 of present embodiment, Yarn relaxation eliminating device 12 constitutes the yarn tension fluctuation that can absorb between this Yarn relaxation eliminating device 12 and the coiler device 13.
Thus, can prevent the yarn tension fluctuation between Yarn relaxation eliminating device 12 and the coiler device 13, the yarn tension between Yarn relaxation eliminating device 12 and the spinning apparatus 9 is impacted.Consequently, can further improve yarn quality.And, because Yarn relaxation eliminating device 12 has the dual-use function of carrying spun yarn 10 and adjusting yarn tension concurrently, therefore carry and compare with the existing structure of parts with tension adjustment with being respectively equipped with yarn, can cut down the amount of parts of spinning frame 1 and suppress cost with parts.
