Thus, can eliminate in spinning speed in spinning apparatus 9 and coiler device 13Winding speed for example, because of the undesirable condition in the inconsistent situation of certain reason (spin 10 lax etc.).

On the position between spinning apparatus 9 and yarn accumulation device 12, be provided with spinning sensor (the1 test section) 52 and yarn quality measuring appliance (the 2nd test section) 57. Spun by spinning apparatus 9The above-mentioned yarn quality measuring appliance 57 of spinning 10 process before being reeled by yarn accumulation device 12 and spinningSensor 52.

The spinning 10 of yarn quality measuring appliance 57 use diagram abridged capacitance type sensors supervision walkingsThickness. Yarn quality measuring appliance 57 is detecting that spinning 10 yarn defect (deposits in the thickness of spinning 10 etc.In abnormal place), yarn defect detection signal is sent to not shown cell controller.In addition, yarn quality measuring appliance 57 is not limited to capacitance type sensor, can be also for example to use upPenetrate the structure of the thickness of formula sensor monitoring spinning 10.

Spinning sensor 52 is configured in the downstream of adjacent yarn quality measuring appliance 57. Spinning sensor52 detect the tension force of the spinning 10 of walking, and its testing result is sent to said units controller. UnitController detects the abnormal places such as tender yarn by the supervision tension force that sensor 52 detects that spins. CauseThis, cell controller can be described as abnormity detection portion. For example, the weak strength of the part spinning 10 of tender yarn,At the partial tension step-down of tender yarn. Therefore, cell controller passes through according to the detection of spinning sensor 52Result monitors the variation of the tension force of spinning 10, can detect tender yarn.

Like this, in this example, because spinning unit 2 possesses for the thickness of detection spinning 10 differentNormal yarn quality measuring appliance 57 and the abnormal spinning sensor 52 of tension force that is used for detecting spinning 10,Therefore can positively detect the abnormal of spinning 10.

In addition, because yarn accumulation device 12 described above plays a kind of buffer, therefore canThe variation that prevents winding tension in coiler device 13 is delivered to than yarn accumulation device 12 by upstream side.In this example due to yarn quality measuring appliance 57 and spinning sensor 52 are configured in than yarn and are depositedLong-pending top trip one side of device 12, the shadow that not changed by the winding tension in coiler device 13Detect the abnormal of spinning 10 loudly.

Cell controller is detecting spinning 10 with yarn quality measuring appliance 57 or spinning sensor 52In the situation in abnormal place, detect this abnormal reason, with suitable display unit demonstration. For example, existDetect in the inhomogeneous situation of specific periodicity thickness of yarn with yarn quality measuring appliance 57, canThink that rotary part (being specially draw roll) has produced certain problem. Therefore, cell controller is in inspectionMeasure in the inhomogeneous situation of the thickness of yarn of specific period, detect the problem of draw roll, show with above-mentionedShowing device shows this order.

And the turn air-flow that 10 the tender yarn of for example spinning produces in spinning apparatus 9 becomes unstableTime generation. Become unsettled reason as turn air-flow, can think the abnormal of spinning apparatus 9(for example fiber of air jetting nozzle 27 stops up, in the delay of the fiber of spinning room 26 inside, rightThe accumulation of the winding of the fiber of hollow guiding axis body 23 and/or the finish on hollow guiding axis body 23Deng). Therefore, cell controller is a little less than the hypotonia detecting according to spinning sensor 52 detectsIn the situation of yarn, the fiber that detects air jetting nozzle 27 as the reason of this tender yarn stops up, is spinningThe winding of the delay of the fiber of 26 inside, chamber, the fiber to hollow leading axle body 23, guide in hollowAt least some in the accumulation of the finish on axis body 23, is presented at above-mentioned display unit by its order.

As described above, when spinning 10 abnormal being detected, by its reason is presented at suitablyDisplay unit in, the operator of spinning frame 1 can carry out the reparation in abnormal place exactly.

Said units controller is when tying according to the detection of yarn quality measuring appliance 57 or spinning sensor 52Fruit detects in 10 when abnormal in spinning, stops from the ejection of the air of air jetting nozzle 27. Thus,Because the spinning of the spinning 10 in spinning apparatus 9 stops, therefore in the position of spinning apparatus 9 spinning 10Intensity low, this spinning 10 is cut off as being torn off. Therefore, spinning apparatus 9 also can be described as and spinsThe shut-off mechanism of yarn 10.

Spinning 10 than the place downstream of having cut off is wound up in package 45 for the time being. In addition,Now be winding in the spinning 10 in package 45 and comprise and passed with yarn quality measuring appliance 57 or spinningThe abnormal place that sensor 52 detects. And cell controller stops drafting system 7, and makesCoiling in coiler device 13 also stops. Then, cell controller sends and controls letter to joint chassis 3Number, make its walking to detecting before the abnormal spinning unit 2 of spinning 10.

Joint chassis 3 use suction pipes 44 and suction nozzle 46 attract to catch yarn end and the volume of spinning apparatus 9 one sidesFill the yarn end of 45 1 sides. Now, the anomalous field suction nozzle 46 used being wound up in package 45 attracts alsoPull-out. Thus, the abnormal place detecting is removed. Then, suction pipe 44 and suction nozzle 46 will attractThe yarn end capturing guides to piecing devices 43, in these piecing devices 43, carries out joint action.

By above joint action, the abnormal place of spinning 10 is removed, and can restart to volumeFill the coiling of 45 spinning 10.

In addition, as mentioned above, extremely (a little less than being mainly of the spinning 10 that spinning sensor 52 detectsYarn) reason mostly be the abnormal of spinning apparatus 9. This example is because spinning sensor 52 is configuredIn the downstream of adjacent spinning apparatus 9, therefore, can (spin and fill in the place of adjacent abnormal generationPut 9) near abnormal (tender yarn) that detects spinning 10. Therefore, can fast detecting go out that tender yarn producesResult is to attract the length of the spinning 10 of removing to shorten with suction nozzle 46. As a result, joint chassis 3The efficiency of the joint operation of carrying out also improves, and can improve the whole production efficiency of spinning frame 1.

The structure of the spinning sensor 52 that the spinning frame 1 of this example possesses is then described.

As shown in Figure 4 and Figure 5, spinning sensor 52 possess yarn guide 60, supporting arm 61,Bottom 62 and strain transducer (detector) 63. As shown in Figure 5, spinning sensor 52 makes walkingSpinning 10 configure contiguously with yarn guide 60.

By making yarn guidingDevice 60 is approximate circle column, with the orthogonal cross section (Fig. 5) of the axis 64 of this cylinder in, yarn drawsLeading device 60 is circular-arc with the contour shape of spinning 10 contact portions. Therefore, due to yarn guide60 do not have sharp parts with spinning 10 parts that contact, and therefore this yarn guide 60 can not damage10 ground that spin guide.

As shown in Figure 4, in yarn guide 60, be formed with undergauge at the central portion of axis 64 directionsPortion 65. By formed like this reducing diameter part 65 on yarn guide 60, connect with yarn guide 60Touch the spinning 10 of walking at the position walking of reducing diameter part 65. Thus, owing to being drawn by yarn guide 60The walking path of the spinning 10 of leading is stable, therefore can prevent that this spinning 10 is de-from yarn guide 60Go out.

Above-mentioned yarn guide 60 is installed in the top of supporting arm 61. This supporting arm 61 is for bending toRight angle, be formed as the metal bar-like member of approximate L word shape. By solid above-mentioned yarn guide 60Fix on one end of supporting arm 61 another distolateral being fixed on bottom 62 of supporting arm 61. Bottom62 for being formed as approximate rectangular-shaped metal parts. Being pasted with on the surface of bottom 62 should for detectingThe strain transducer (deformeter) 63 of the distortion of bottom 62. On bottom 62, make this bottom 62 distortionEasily be formed with thinner wall section 62a. Above-mentioned strain transducer 63 is secured on thinner wall section 62a.

The power being applied on yarn guide 60 is delivered to bottom 62 by supporting arm 61, makes this endPortion 62 is out of shape. The distortion of this bottom 62 utilizes strain transducer 63 to detect. Strain transducer 63 willThe signal of telecommunication corresponding with the strain facies detecting sends to cell controller. Therefore, cell controller energyEnough in being applied to the power on yarn guide 60 from the electrical signal detection of strain transducer 63. SeparatelyOutward, the spinning sensor 52 of this structure has easy detection and is applied to the power on yarn guide 60Direction. For example, in the case of the spinning sensor 52 of this example, yarn guide 60Easily detect the power (power of the direction representing with arrow in Fig. 4 and Fig. 5) of the direction that approaches bottom 62.The detection side who this direction is called to the sensor 52 that spins to.

Here the 10 bending walkings by contacting with yarn guide 60 of considering to spin as Fig. 5Situation. Because effect in this spinning 10 has tension force, therefore spin and 10 want to get back to linear state. As a result,Due to spinning 10 extruding yarn guides 60, therefore power is now detected by strain transducer 63.The tension force that acts on spinning 10 is higher, and the power that yarn guide 60 is pushed in this spinning 10 becomes larger.Therefore, the tension force of the spinning 10 of walking is exported and acted on to the strain transducer 63 of spinning sensor 52The corresponding signal of telecommunication of size. Utilize said structure, cell controller can detect opening of spinning 10Power. In addition, for precision detects spinning 10 tension force well, 10 extruding yarns preferably make to spinThe direction of guide 60 as far as possible with above-mentioned detection side to consistent (state of Fig. 5).

By (Fig. 5) spinning 10 in the time that axis 64 directions of yarn guide 60 are seen and this yarn guidingThe central angle of the circular arc of the part of the periphery contact of device 60 is defined as contact angle θ. In spinning 10In the identical situation of tension force, contact angle θ is larger, and the power that acts on yarn guide 60 becomes larger.Therefore,, in order to detect the trickle tension change of spinning 10, preferably make contact angle θ large as much as possible.

Patent documentation 2 discloses at the upstream side of yarn tension detecting mechanism and downstream guide portion has been setPart, by maintaining the yarn guiding to yarn tension detecting mechanism with this guide member Shi Sha road bendingThe structure of the contact angle of device. But, if unnecessary like this guide member is present in spinning Sha roadIn, the worry that exists this guide member that yarn quality is adversely affected. And, with guidingIt is also limited that the structure of parts Shi Sha road bending increases contact angle.

The spinning frame 1 of this example appends guide member unlike patent documentation 2, makes to yarnThe contact angle θ of the spinning 10 of guide 60 forms as wide as possible.

First, in order to illustrate, by parallel with the spinning 10aSha road of the upstream side of yarn guide 60Direction as Y direction (the 1st direction), will (spinning be single with the body left and right directions of spinning frame 1Unit 2 and column direction) (draw roll axially) parallel direction is as X-direction (the 2nd direction),To with Y direction and the orthogonal direction of X-direction (be more specifically and Y direction and X-directionThe direction of the planar quadrature forming) as Z-direction (the 3rd direction).

As shown in Fig. 1 of patent documentation 2 waits, the axial and spinning Sha road of yarn guide just in the pastHand over ground configuration. Therefore as shown in Figure 6A, can think yarn guide 60 in the time of Z-directionThe direction of axis 64 and Y direction to configure be orthogonally that practitioner the most naturally conceives. Yarn guidingThe reference position of device 60 using the state of configuration like this as spinning sensor 52.

The present application persons have studied as shown in Fig. 6 B yarn guide 60 with respect to spinning10Sha road configures obliquely. That is, if clear as Fig. 6 A and Fig. 6 B are compared,By the axis of yarn guide 60 64 is configured obliquely with respect to spinning 10Sha road, spinning 10Elongated with the length that this yarn guide 60 contacts. Therefore, with the spinning of the reference position shown in Fig. 6 AYarn sensor (structure of prior art) is compared, as Fig. 6 B with spinning 10Sha road obliquelyThe spinning sensor 52 of configuration, becomes large with respect to the contact angle θ of the spinning 10 of yarn guide 60.

Be conceived to above point, the spinning sensor 52 of this example configures as follows. , as Fig. 7Shown in, under the state having tilted with respect to axis 64 in spinning 10, join contiguously with yarn guide 60Put spinning sensor 52. Be more specifically, in the time of Z-direction (Fig. 7), to make yarn guide60 axis 64 is with respect to the spinning 10aSha road direction (Y by upstream side than yarn guide 60Direction of principal axis) configuration spinning sensor 52 obliquely. Therefore, the spinning sensor 52 of this exampleCan be described as from reference position (position that makes the orthogonal Fig. 6 A of axis 64 and Y direction) with Z axisCentered by rotatably configuration.

Thus, the spinning sensor 52 of this example with by the axis of yarn guide 60 64 and YThe existing structure (structure of Fig. 6 A) of direction of principal axis orthogonal configuration is compared, and can increase with respect to yarn and drawLead the contact angle θ of the spinning 10 of device 60. Therefore, the spinning sensor 52 of this example is with existingSome structures are compared, and can detect the trickle tension change of spinning 10, the detection that can improve tender yarnPrecision. And said structure is owing to being the structure only yarn guide 60 being configured obliquely, thereforeAs patent documentation 2, be not used for maintaining contact angle θ and necessity of guide member is set. Therefore,Do not have unnecessary guide member to make to spin and 10 be subject to dysgenic worry.

In this example as shown in Figure 8, in the time of X-direction, yarn accumulation roller 14 upperTrip side end be configured in than yarn guide 60 by the depth position in Z-direction (spinning frame 1Yi Ce position, the back side) on. In other words, in the time of X-direction, the upstream of yarn accumulation roller 14Side end is positioned at than the extended line that the spinning 10aSha road of the upstream side of yarn guide 60 extended66 back side one sides by spinning frame 1.

Like this, because yarn accumulation roller 14 is configured in depth to the position of the rear side of spinning frame 1,Therefore spin 10 be positioned at the top trip side position of adjacent yarn accumulation roller 14 yarn guide 60 positionBe set up bending walking widely. Like this, by make spinning 10 bendings of guiding with yarn guide 60,Because spinning 10 is wrapped in the 60 Shangdis walkings of yarn guide, therefore with respect to yarn guide 60It is large that the contact angle θ of spinning 10 becomes. Thus, can further improve the detection of spinning sensor 52Precision.

In addition, as mentioned above, in patent documentation 2 in order to make the yarn of the spinning contacting with yarn guideRoad is bending and be provided with guide sections part. In this example due to the yarn of yarn accumulation device 12Line stockpiles the bending of Gun14Shi Sha road, therefore can say that this yarn accumulation device 12 doubles as patent documentation 2Guide member. Like this, 12 of the yarn accumulation devices of this example are used for increasing and guide to yarnThe effect of the curved guide device (guide member) of the contact angle θ of the spinning 10 of device 60. According to thisStructure, just can increase contact angle θ owing to need not resetting guide member, therefore not due toThis guide member makes the affected worry of yarn quality.

In this example as shown in Figure 8, the detection of the sensor 52 that makes to spin in the time of X-directionThe spinning 10a of the upstream side of direction (direction representing by thick-line arrow in Fig. 8) and yarn guide 60The angular bisector of the angle that the spinning 10bSha road in the downstream of Sha road and yarn guide 60 forms is largeBody as one man configures. Therefore,, in the time of X-direction, the detection side of spinning sensor 52 is to relativelyConfigure obliquely in Z-direction. Thus, owing to can making by the spinning of yarn guide 60 bendings10 impose on the direction of power of above-mentioned yarn guide 60 and the detection side of spinning sensor 52 to substantiallyUnanimously, therefore can detect rightly the tension change of above-mentioned spinning 10.

As shown in Figure 9, in the time of Y direction, than the spinning of yarn guide 60 downstreams10b tangential direction along this yarn accumulation roller 14 when being wound up on yarn accumulation roller 14 is walked. CauseThis, in this example in the time of Y direction, the detection side of the sensor 52 that makes to spin to yarnStockpile the tangential direction ground unanimous on the whole tilted configuration spinning sensor 52 of roller 14. Thus, can be with spinningYarn sensor 52 detects rightly via yarn guide 60 and is winding to spinning on yarn accumulation roller 14The tension force of yarn 10.

In addition, as mentioned above, due to make when the Y direction detection side to than yarn guideThe spinning 10bSha road of the 60 downstreams sensor 52 that as one man makes to spin tilts, therefore at this YWhile seeing on direction of principal axis, the axis 64 of yarn guide 60 tilts with respect to X-direction and Z-direction.

As described above, the yarn that sensor 52 possesses that spins in the spinning frame 1 of this example drawsAxis 64 direction all with respect to X-direction, Y direction and Z-direction of leading device 60 tiltsGround configuration. , join on the yarn guide 60 three-dimensional tilt ground of the spinning sensor 52 of this examplePut. Thus, with the existing structure that the axis 64Yu Sha road of yarn guide 60 is configured orthogonally (figureThe structure of 6A) compare, can further increase the contact with respect to the spinning 10 of yarn guide 60Angle θ, spinning sensor 52 can more positively detect the tension change of this spinning 10.

And, omitted although illustrate, for sensor 52 three-dimensional tilt as described above that will spinGround configuration, the bottom 62 of this spinning sensor 52 is installed in body main body by special base.For the posture supporting spinning sensor 52 with three-dimensional tilt, above-mentioned base adopts three-dimensional twisted complexityShape. Therefore, in this example, be relatively easy to resin with moulding and form above-mentioned base.

In addition, due to spinning 10 limits and the 60 contact edge walkings of yarn guide, sensor therefore spins52 is charged. Therefore, in this example above-mentioned base with metal or added the electroconductive resin structure of carbonBecome. Thus, owing to the static of band in spinning sensor 52 can being bled off, therefore can suppress spinningThe output signal of sensor 52 is uneven, can further improve the detection essence of spinning sensor 52Degree.

The lid 68 of the spinning sensor 52 of this example is then described.

As shown in figure 10, the spinning sensor 52 of this example possesses yarn guide 60, supportingArm 61, bottom 62 and the lid 68 from outer side covers strain transducer 63 etc. , if yarn drawsLead device 60 or supporting arm 61 etc. and expose, become the careless touching of for example operator and the reason of damage.Therefore,, by covering yarn guide 60 etc. with covering 68 as described above, sensor 52 prevents from spinningDamage.

As shown in figure 10, on lid 68, be formed with the gap 69 that allows yarn guide 60 expose use. CauseThis, the spinning 10 of walking can contact with yarn guide 60 by gap 69.

Gap 69 is can make 10 modes of passing through of spinning slenderly form. Therefore, gap 69 is ownThere is the function of guiding spinning 10 walkings. More specifically as follows. , carrying out joint with joint chassis 3When operation, the coiling of the spinning 10 to package 45 of carrying out with coiler device 13 interrupts. Therefore, connectPay enough tension force to when operation spinning 10. Therefore, when joint operation due to spinning 10A little less than the power of extruding yarn guide 60, therefore there is spinning 10 from yarn guide 60 (reducing diameter part 65)The situation of deviating from.

According to said structure, contact with yarn guide 60 walking spinning 10 lid 68 on formThe inner side walking in elongated gap 69. Therefore, even spin 10 from yarn in the time of such as joint operation etc.Wire conductor 60 is deviate from, and also can guide this spinning 10Sha roads with gap 69. , even if connecingAlso can and be directed to yarn accumulation device with the 69 guiding spinning 10 of the gap of lid 68 when operation etc.12. Therefore,, in this example, can say that the lid 68 of spinning sensor 52 doubles as yarn accumulationUpstream side guide. In the spinning apparatus of prior art, there is the upstream at yarn accumulation deviceSide arranges the necessity that spinning is directed to the guide of this yarn accumulation device, but in this example byDouble as this guide in lid 68, therefore can omit above-mentioned guide.

In addition, as previously mentioned, in this example in the time of Y direction, by yarn guide 60Axis 64 configure obliquely with respect to X-axis and Z axis. Therefore, cover yarn guide 60 gradesLid 68 is also configuration obliquely in the time of Y direction. Specifically as shown in figure 10, in Y directionWhile seeing, the length direction in gap 69 configures and covers 68 obliquely with respect to Z axis.

Illustrate along band, be equipped with in the spinnery of spinning frame 1, in maintenance or cleaning etc.Shi Jinhang is from installing a positive side (front one side of spinning frame 1) (from Z-direction) air cannon etc.Blow out air and yarn bits etc. are blown to the operation flying. In Figure 10, represent spinning sensor by thick-line arrowThe direction of 52 blow out air. In this operation, due to for yarn bits etc. are blown and fly to use sizable application of forceBlow out air, the application of force that therefore according to circumstances may produce air makes each several part damage. This exampleIn because gap 69 as described above configures obliquely with respect to Z axis, while therefore seeing from Z-direction,The area that exposes of yarn guide 60 diminishes. Therefore, even from installing a positive side (Z-direction)To spinning sensor 52 blow out air, also can weaken the application of force of the air that impacts yarn guide 60,Therefore can prevent that yarn guide 60 is because air sustains damage.

As described above, the spinning frame 1 of this example possesses spinning apparatus 9, reeling fillsPut 13 and spinning sensor 52. Spinning apparatus 9 generates spinning 10. Coiler device 13 will be by spinning dressPutting the spinning 10 of 9 generations reels to package 45. Spinning sensor 52 is at spinning apparatus 9 and the dress of reelingPut the tension force that detects the spinning 10 of walking between 13. Spinning sensor 52 possesses the spinning 10 of the walking of makingThe yarn guide 60 of contact and export the signal corresponding with the power on yarn guide 60 of being applied toStrain transducer 63. Yarn guide 60 at least with spinning 10 parts that contact with axis 64Cross section profile shape in orthogonal cross section is formed as approximate circle arc. Yarn guide 60 is in spinning 10Under the state tilting with respect to axis 64, configure contiguously with this yarn guide 60.

Like this, by configuring obliquely yarn guide 60 with spinning 10Sha road, Yu Tongsha road is orthogonalConfigured yarn guide 60 existing structure compare, can increase with respect to yarn guide 60The contact angle θ of spinning 10. Thus, can positively detect the tension change of spinning 10.

The spinning frame 1 of this example possesses and offers spinning apparatus 9 with draw roll drawn fiber bundle 8Drafting system 7. By the direction parallel with the spinning 10aSha road of the upstream side of yarn guide 60As Y direction, using with the direction of the axially parallel of draw roll as X-direction, will with Y-axis sideTo the direction of the planar quadrature forming with X-direction as Z-direction. In the time of Z-direction,The axis 64 of yarn guide 60 configures obliquely with respect to Y direction.

Thus, can increase the yarn guide 60 with respect to the spinning 10a along Y direction walkingContact angle.

The spinning frame 1 of this example possesses and pulls out and stockpile from the spun spinning 10 of spinning apparatus 9Yarn accumulation device 12. 12 of yarn accumulation devices make the yarn of the spinning 10 in the time of X-directionThe effect of the curved guide device of road bending.

Thus, due to the contact angle that can further increase with respect to the spinning 10 of yarn guide 60Spend θ, therefore can more positively detect the trickle tension change of spinning 10. Due to yarn accumulation dressPut 12 functions that have curved guide device concurrently, the amount of parts that therefore can cut down spinning frame 1. And,Due to the necessity not resetting for the curved guide device of the 10Sha road bending that makes to spin, therefore alsoNot because making to spin, unnecessary guide 10 is not adversely affected.

In the spinning frame 1 of this example, spinning sensor 52 is configured on yarn direction of travelBetween spinning apparatus 9 and yarn accumulation device 12. Coiler device 13 will draw from yarn accumulation device 12The spinning 10 going out is reeled to package 45.

Accordingly, can directly detect from the spun spinning 10 of spinning apparatus 9 with spinning sensor 52Tension force. Therefore, owing to detecting the abnormal of spinning 10 near the abnormal position occurring, thereforeCan earlier detection tender yarn. And, due to yarn accumulation device 12 be configured in spinning sensor 52 withBetween coiler device 13, therefore yarn accumulation device 12 moves as a kind of buffer, coiler deviceIn 13, the variation of winding tension can not be delivered to spinning sensor 52. Therefore, spinning sensor 52 is notBe subject to the impact of winding tension, can detect exactly the tension force of the spinning 10 generating in spinning apparatus 9.

In the spinning frame 1 of this example, spinning sensor 52 from outer side covers yarn guide60 and the lid 68 of strain transducer 63 double as the yarns to yarn accumulation device 12 by spinning 10 guidingAccumulating device upstream side guide.

Thus, can positively spinning 10 be imported to yarn accumulation device 12. And, due to lid 68Double as yarn accumulation device upstream side guide, the spinning machine that therefore can omit prior art possessesThe upstream side guide of yarn accumulation device.

In the spinning frame 1 of this example, on lid 68, yarn guide 60 is exposed to outside landformBecome to have gap 69. In the time of Y direction, the length direction in gap 69 and Z-direction are obliquelyConfiguration.

,, while seeing from body front (Z-direction), make the yarn guide 60 via gap 69The area that exposes diminish to configure and cover 68. Thus, though cleaning use air from body front to covering 68Blow out, this air does not directly impact yarn guide 60 yet, therefore can prevent this yarn guide 60Damage.

In the spinning frame 1 of this example, the axis 64 of yarn guide 60 is with respect to Y-axis sideTilt to, X-direction and all directions of Z-direction.

, making yarn guide 60 three-dimensional tilts configures. Thus, can further increase with respect toThe contact angle θ of the spinning 10 of yarn guide 60, can more positively detect the trickle of spinning 10Tension change.

The spinning frame 1 of this example possesses the cell controller as abnormity detection portion. Spinning apparatus 9For thering is fiber guide portion 22, formed nozzle carrier 35 and the hollow leading axle of air jetting nozzle 27Body 23, utilize turn air-flow in drafted device 7 drawing-offs of spinning room 26 inside spinning fibre bundle 8And the open end spinning apparatus of generation spinning 10. Cell controller is according to the detection knot of spinning sensor 52It is abnormal that fruit detects the tension force of spinning 10.

That is, if in open-end spinning formula spinning apparatus 9, exist abnormal, spin the yarn that tension force is low (a little less thanYarn). Therefore, can detect the abnormal of spinning apparatus 9 by spin 10 tension force of detection.

In the spinning frame 1 of this example, show spinning 10 in the testing result of spinning sensor 52The situation of hypotonia under, cell controller detects air spray as the abnormal of open end spinning apparatusThe fiber of delivery nozzle 27 stops up, in the fiber retention of spinning room 26 inside, to hollow guiding axis body 23Filament-wound Machine and at least some in piling up of finish on hollow guiding axis body 23.

That is, as fruit fiber is blocked in air jetting nozzle 27, the gas flow of the turn of spinning room 26 streamAmount reduces. As a result, owing to can not make fibre high-speed rotation in spinning room 26, what therefore generate spinsThe sth. made by twisting of yarn 10 dies down. And, if fiber retention in spinning room 26 or Filament-wound Machine inThe top of empty guiding axis body 23 or finish have been deposited in the top of hollow guiding axis body 23, existThe fiber of spinning room 26 interior turns can not be with high speed turn. As a result, the sth. made by twisting of the spinning 10 of generation becomesA little less than. Twist with the fingers weak yarn owing to being loose soft state, therefore hypotonia. Therefore, low by tension forceUnder detection can detect the abnormal of open end spinning apparatus.

The spinning frame 1 of this example also possesses suction pipe 44 and suction nozzle 46 and piecing devices 43. ?Cell controller detects that, in the abnormal situation of spinning 10, spinning apparatus 9 stops spinning, will spin10 cut off. Suction pipe 44 and suction nozzle 46 attract from spinning apparatus 9 in the situation that spinning 10 has been cut offThe yarn end of the spinning 10 coming and from the yarn end of the spinning 10 of coiler device 13, different by spinning 10Normal place attracts to remove. Piecing devices 43 carry out the spinning 10 that attracted by suction pipe 44 and suction nozzle 46Joint operation between yarn end.

As previously mentioned, because spinning sensor 52 detects the different of spinning 10 near abnormal occurrence positionsOften, therefore in the case of occurred to spin 10 abnormal can detect immediately and spinning 10 is cutDisconnected. Therefore, owing to can shortening the length that must attract with suction nozzle 46 spinning 10 of removing, thereforeIt is good that the joint operation that piecing devices 43 carry out also can efficiency. As a result, can improve spinning frame 1Production efficiency.

The spinning frame 1 of this example also possesses the thickness detecting by the spun spinning 10 of spinning apparatus 9Abnormal yarn quality measuring appliance 57.

Thus, due to can detect the abnormal and thickness of spinning 10 tension force extremely the two, therefore canDetect more accurately the abnormal of spinning 10.

In the spinning frame 1 of this example, yarn guide 60 is in a part for axis 64 directionsOn have reducing diameter part 65, spinning 10 on reducing diameter part 65 walking.

Thus, can not come off and make to spin 10 walkings from yarn guide 60. Therefore, spinning passesSensor 52 can positively detect the tension force of spinning 10.

The variation of above-mentioned example is then described. In addition, in the following description, for upperState the common structure of example, add identical Reference numeral in key element name, description thereof is omitted.

In this variation, cell controller detects heart yarn according to the testing result of spinning sensor 52Have or not. That is, generating in the spinning frame 1 of covering yarn, at heart yarn for a certain reason not by normallyIn situation about providing, when with normal covering yarn compared with the intensity step-down of yarn, therefore spinning passesAlso step-down of the tension force of the yarn that sensor 52 detects. Therefore, cell controller is by the supervision sensor that spinsThe variation of the tension force of 52 yarns that detect can detect having or not of heart yarn. Like this, in this variation,Can say that cell controller plays heart yarn test section.
