Summary of the invention

In the structure of above patent document 1, after air spinning device stops spinning, the downstream of yarn accumulation device Yarn be cut off, and pass through the remaining yarn that is wrapped in yarn accumulation device of remaining yarn suction device removing.Therefore, patent document 1 Structure need to be wrapped in yarn accumulation device there is a certain amount of remaining yarn to remove, and need that yarn defect will be removed Amount yarn from package unwind, therefore, the quantitative change for the yarn being removed is more, and the time for connecing the yarn period also can be elongated.

In patent document 1, yarn monitoring device configuration is near winder, therefore, because when yarn passes through winding Portion and yarn can be reduced by the influence of traversing, the measurement accuracy of yarn monitoring device when being wound in package.

The object of the present invention is to provide one kind, and the measurement of yarn monitoring device can be maintained to high-precision, can subtract The amount of few the end of a thread simultaneously can be shortened the air spinning machine and air spinning method for connecing the time in yarn period.

First viewpoint according to the present invention provides the air spinning machine with flowering structure.That is, the air spinning equipment is for air Spinning apparatus, yarn accumulation roller, winding device, yarn monitoring device and control unit.The air spinning device utilizes convolution Air stream generates spinning yarn to fibre bundle twisting.Spinning yarn described in the yarn accumulation roller accumulation.The winding dress It sets winding accumulation and forms package in the spinning yarn of the yarn accumulation roller.The yarn monitoring device configuration is in institute It states between air spinning device and the yarn accumulation roller, the long defect and shortage for being able to detect the spinning yarn are fallen into.Institute Control unit is stated in the case where detecting the long defect in the spinning yarn by the yarn monitoring device, in the length At least part accumulation of defect stops the rotation of the package, to interrupt base in the state of the yarn accumulation roller In the winding for the spinning yarn that the winding device carries out.

It is shorter from the length of the spinning yarn of package unwinding thereby, it is possible to prevent long defect to be wound in package, because This can reduce the amount of the end of a thread, and also can be shortened the time for connecing the yarn period.It is metastable by the traveling in spinning yarn Position configures yarn monitoring device, can maintain the measurement accuracy of yarn monitoring device higher.

In the air spinning machine, it is preferable that the control unit by the yarn monitoring device in the spinning yarn In the case where detecting that the shortage is fallen into line, the yarn on the direction of travel of the spinning yarn is fallen into the shortage The mode in the downstream of line accumulation roller stops the rotation of the package.

As a result, detect shortage fall into before accumulation in yarn accumulation roller normal spinning yarn (hereinafter also referred to " normal yarn ") it is wound in package, therefore, it can be reduced the amount of the end of a thread in the case where shortage is fallen into removing, and The time for connecing the yarn period can be shortened.

In the air spinning machine, it is preferable that the control unit by the yarn monitoring device in the spinning yarn In the case where detecting that the long defect or the shortage are fallen into line, the spinning that will be carried out based on the air spinning device The generation of yarn is interrupted, and the yarn ends for the spinning yarn for being wound in the package are generated.

As a result, in the case where detecting the defect of yarn, the generation by interrupting spinning yarn can be avoided spinning The unhelpful generation of yarn.In addition, since spinning yarn is cut-off by the stopping spinned, so without separately setting cutting The device of spinning yarn.Therefore, it is possible to realize the simplification of structure.

In the air spinning machine, it is preferable that have the first removing device, which configures in the yarn Near line accumulation roller, and the long defect for including by the spinning yarn removes.

Thereby, it is possible to remove long defect using attraction air stream.In addition, can be to use the simple structure of opening and closing member real Matter switches the movement of the first removing device and movement stops.

In the air spinning machine, it is preferable that the control unit the yarn accumulation roller rotation stop after, While opening the opening and closing member or after opening the opening and closing member, invert the yarn accumulation roller.

It is easy to capture the long defect by the first removing device as a result, and the long defect can be rapidly removed.

In the air spinning machine, it is preferable that have the second removing device, which rotatably matches The shortage set in the downstream side of the yarn accumulation roller, and include by the spinning yarn, which is fallen into, to be removed.

As a result, the case where the timing for falling into the downstream side for being configured at yarn accumulation roller with shortage stops the rotation of package Under, the shortage can be easily removed by the second removing device to be fallen into.

In the air spinning machine, it is preferable that second removing device is capturing the spinning from the package Yarn yarn simultaneously directs it in the process of yarn splicing device, and the shortage for including by the spinning yarn, which is fallen into, to be removed.

Thus, it is possible to which separately setting does not remove the sunken process of shortage, so as to shorten the time for connecing the yarn period.In addition, Second removing device can be used as to the device to yarn splicing device guidance spinning yarn.Therefore, it is possible to realize the simplification of structure.

In the air spinning machine, it is preferable that the control unit makes the yarn after the rotation of the package stops The rotation of line accumulation roller stops.

It is stored in the yarn ends for the spinning yarn that the upstream side of yarn accumulation roller is cut off in the yarn for being winding to rotation After staying roller, slightly put while maintaining from the outer peripheral surface of yarn accumulation roller state slightly away due to centrifugal force It is dynamic.By making this state continue longer time, it can prevent the yarn ends from twining to accumulation in the yarn of yarn accumulation roller Layer.

In the air spinning machine, preferably with flowering structure.It is filled that is, the air spinning equipment detects for accumulation yarn It sets.The accumulation Yarn detection device detects the presence of accumulation in the spinning yarn of the yarn accumulation roller.The control Portion is detected by the accumulation Yarn detection device in the yarn when the yarn monitoring device detects that the shortage is fallen into On line accumulation roller after spinning yarn described in non-accumulation, separates certain time and stop the rotation of the package.

As a result, when the rotation of package stops, shortage can be made to fall into positioned at the downstream of yarn accumulation roller.

In the air spinning machine, preferably with flowering structure.That is, the air spinning equipment is for Yarn detection device and sky Gas spraying device.The Yarn detection device configuration detects institute between the yarn accumulation roller and the winding device State spinning yarn traveling yarn road in whether there is or not the spinning yarns.The air jet system configuration is in the yarn accumulation roller Air is sprayed between the winding device, and to the yarn road.The control unit is carried out based on the air spinning device The spinning yarn generation be interrupted after, make the package along the coiling direction rotation for winding the spinning yarn on one side It on one side sprays the air based on the air jet system to carry out.If spraying in the air jet system the yarn road empty When gas, detect that the spinning yarn is not present in the yarn road by the Yarn detection device, then the control unit makes institute The rotation for stating package stops.

Thereby, it is possible to rapidly and be detected positively the upstream side of yarn accumulation roller be cut off spinning yarn yarn This case is left from yarn accumulation roller in end.

In the air spinning machine, it is preferable that it is 70mm or more 110mm or less that the yarn accumulation roller, which has diameter, Reserving portion.

Thereby, it is possible to stop the winding of package, and energy in the state that long defect certainly remains on yarn accumulation roller Shorten and handles the time required for removing long defect.

In the air spinning machine, it is preferable that the yarn accumulation roller is capable of the spinning yarn of accumulation 10m or more Line.

Even the long defect of 10m or more as a result, can also stop in the state that long defect remains on yarn accumulation roller The winding of package.

As shown in Figure 1, each spinning unit 100 mainly has drafting system 2, the air configured in order from upstream towards downstream Spinning apparatus 3, yarn monitoring device 4, yarn accumulation device 5, yarn splicing device 6 and winding device 7.

Drafting system 2 has multiple (being in the present embodiment four) drawing rollers and with opposite with each drawing rollers Multiple (being in the present embodiment four) opposed rollers for configuring of mode.Drafting system 2 is in drawing rollers and opposed roller Between sandwich and convey the sliver 8 that supply via sliver guiding device of bar cylinder omitted from diagram, thus by the stretching of sliver 8 (drawing-off) Fibre bundle 9 is generated to defined fibre weight (or thickness).

Aforementioned four drawing rollers are followed successively by rear roller 21, third roller 22, the dragon for being equipped with rubber system from upstream side With 23 middle roller 24 and front roller 25.Each drawing rollers are driven in rotation with defined revolving speed.After control unit 90 is by control The rotation for the drawing-off motor 91 stated and the revolving speed that each drawing rollers can be controlled.Control unit 90 be based on air spinning device 3 The formation speed of spinning yarn 10 cooperatively suitably control the revolving speeds of each drawing rollers.One is illustrated in Fig. 4 Drawing-off motor 91, but a drawing-off motor can also be respectively equipped with relative to each drawing rollers.Alternatively, being also possible to only rear roller 21 and third roller 22 driven by common drawing-off motor.

Air spinning device 3 is configured in the downstream side of immediately front roller 25.Air spinning device 3 has what diagram was omitted Spinning jet nozzle, it is empty using the convolution generated by the internal spray compressed air from the spinning jet nozzle to air spinning device 3 Air-flow twists the fibre bundle 9 come from the supply of drafting system 2, to generate spinning yarn 10.

Air spinning device 3 can carry out out yarn and usually spinning based on the control instruction of control unit 90.Yarn Spinning refer to the generation method of spinning yarn 10 and spinning speed it is different with usual spinning and in the beginning of air spinning device 3 or Start again at the spinning movement carried out when the generation of spinning yarn 10.Usually spinning refer to continuously generated after yarn out by The spinning movement for the spinning yarn 10 that winding device 7 is wound.

Spinning yarn detection device 30 is configured in the downstream of immediately air spinning device 3.Spinning yarn detection device 30 Detect the presence of the spinning yarn 10 after air spinning device 3 is just generated and sent out.Spinning yarn detection device 30 for example can Enough use contactless optical sensor or static capacity type sensor etc..

Yarn monitoring device 4 is configured in the downstream side of spinning yarn detection device 30.Yarn monitoring device 4 is saturating by light Cross the sensor of formula monitor traveling spinning yarn 10 quality (thickness etc.), and detect the yarn defect that spinning yarn 10 includes. In addition, yarn monitoring device 4 is not limited to the sensor of light through mode, such as static capacity type sensor also can be used Monitor the quality of spinning yarn 10.

Above-mentioned yarn defect is that spinning yarn 10 has abnormal position, and the shortage including centimetre unit is fallen into and the length of meter Dan Wei lacks It falls into.Shortage is fallen into for example including the part i.e. slubbing thicker than other parts because spinning bad and foreign matter be mixed into, fine fibre phase The group being mutually entwined i.e. cotton knot and the cauline leaf of cotton i.e. impurity etc..Long defect includes spinning because the thickness of sliver 8 is uneven Generated on yarn yarn 10 long partially thin uneven and/or partially it is thick it is uneven, because fibre bundle volume 9 in (wrap up) drafting system 2 Opposed roller and the part that causes spinning yarn 10 to be tapered and lead to HD (Hairiness for some reason Difference: filoplume difference) be abnormality yarn it is uneven etc..In the present embodiment, by the length of abnormal position For 50cm or more yarn defect as long defect, fallen into the length of abnormal position ratio 50cm short yarn defect as shortage.

In the case where detecting yarn defect by yarn monitoring device 4, stop spinning in air spinning device 3, therefore The intensity decline of spinning yarn 10, spinning yarn 10 are cut off in the part of the air spinning device 3.In this way, air spinning fills 3 are set with the function as the cutting portion for cutting off spinning yarn 10 when yarn monitoring device 4 detects yarn defect.In addition, can also Spinning yarn 10 is cut off to use cutter.

As described above, the structure between air spinning device 3 and yarn accumulation device 5 is arranged in yarn monitoring device 4 Compared with yarn monitoring device 4 to be arranged in the structure in downstream side of yarn accumulation device 5, can make yarn defect be located at be cut off Near the yarn ends A (being yarn ends C in Figure 10) of spinning yarn 10.The end of a thread generated when connecing yarn thereby, it is possible to reduce Amount.

The first guiding device 11 is configured in the downstream side of yarn monitoring device 4.First guiding device 11 is in order to carry out connecing yarn When etc. spinning yarn 10 is leaned on to the drawing of yarn accumulation device 5 and is configured to move.First guiding device 11 is configured to by rear State the driving of the first guiding device motor 93 and being capable of the position of readiness shown in the guide position and chain-dotted line shown in solid of Fig. 1 Between rotate.

Tension sensor 40 is configured in the downstream side of the first guiding device 11.Tension sensor 40 is for example configured to load and passes The sensor of sensor formula.The tension of the spinning yarn 10 of 40 pairs of tension sensor travelings is measured, and will be corresponding with the tension Electric signal to control unit 90 export.

Yarn accumulation device 5 is configured in the downstream side of tension sensor 40.Yarn accumulation device 5 has yarn accumulation sieve 51, rotation is drawn to drive the accumulation motor 52 and yarn hooking member 53 of the yarn accumulation roller 51.

It is 70mm or more 110mm reserving portion 51a below that yarn accumulation roller 51, which has diameter, and by the reserving portion The temporarily accumulation spinning yarn 10 of spinning yarn 10 is wound on the outer peripheral surface of 51a.Yarn accumulation roller 51 is formed to accumulation 10m or more (is in the present embodiment the spinning yarn of 50m or more) 10.In such manner, it is possible to pass through 51 accumulation of yarn accumulation roller A large amount of spinning yarn 10, thus be able to detect the accumulation amount of the yarn accumulation roller 51 accumulation Yarn detection device 50 can Fitting limit expands.In Fig. 2, reserving portion 51a is illustrated as the cylindrical shape for having outer diameter fixed.But reserving portion 51a It can be formed as can also having multiple taperings with downstream side is tended to and taper that diameter becomes smaller from upstream side.

The jackshaft that diagram is omitted is equipped between yarn accumulation roller 51 and accumulation motor 52.By the jackshaft between Between, it can reduce the rotary shaft of accumulation motor 52 and the abrasion of bearing.In the jackshaft, the mutually different part of diameter exists It is adjacent to each other in axial direction, as a result, jackshaft is formed as ladder-like.The axis hole of yarn accumulation roller 51 is formed as only among this The relatively thin part positioned at tip side of axis is inserted into.Thereby, it is possible to be easy to carry out determining for yarn accumulation roller 51 Position.In addition it is also possible to jackshaft is not formed as ladder-like.

Yarn hooking member 53 is installed in the downstream end of yarn accumulation roller 51.Yarn hooking member 53 is relative to yarn Line accumulation roller 51 can be supported with the relative rotation.In some in yarn hooking member 53 and yarn accumulation roller 51 Permanent magnet is installed, hysteresis material is installed on another.By these magnetic mechanisms, create antagonism yarn hooking member 53 relative to the torque of this case that 51 relative rotation of yarn accumulation roller.Therefore, only will the power as overcoming the torque Under the case where being applied to yarn hooking member 53 (the case where being applied with the tension of regulation or more), yarn hooking member 53 being capable of phase Yarn accumulation roller 51 is relatively rotated, so that the spinning yarn 10 being wrapped on yarn accumulation roller 51 be unwound.? In the case where the power for overcoming the torque is not applied to yarn hooking member 53, yarn accumulation roller 51 and yarn hooking member 53 integrally rotate, the accumulation spinning yarn 10 on yarn accumulation roller 51.Also it can replace permanent magnet and electromagnet be installed. Also it can replace magnetic mechanism and the drive motor that rotation drives yarn hooking member 53 be set.

Reel cage arm 71 can support the rolling tube 73 for being used to wind spinning yarn 10 in a manner of it can rotate.Reel cage arm 71 can rotate by center of rotation of its base end portion.Even if winding spinning yarn 10 on rolling tube 73 as a result, to be wrapped 70 diameter becomes larger, and also can suitably maintain package 70 and the contact situation of winch spool 72, can continue to the volume of spinning yarn 10 Around.

Winch spool 72 and being passed the driving force of aftermentioned winch spool motor 72a with rolling tube 73 or package 70 It is rotated in the state of the face contact of periphery.It is formed with the traversing slot that diagram is omitted on the outer peripheral surface of winch spool 72, passes through the traversing Slot can make spinning yarn 10 with defined amplitude traversing.In this way, winding device 7 can. while making 10 traversing of spinning yarn It is wound into rolling tube 73, to form package 70.

Then, it is briefly described referring to electrical structure of the Fig. 4 to spinning unit 100.Spinning unit 100 have for State the driving and braking, drawing-off motor 91, spinning valve 92, the first guiding device motor 93, yarn disengaging guiding device of each device Motor 94, the second guiding device motor 95 connect yarn cam motor 96, capture guidance motor 97, air injection valve 98, winch spool motor 72a and winding brake valve 99.

Drawing-off motor 91 is, for example, multiple electric motors, can be respectively with rear sieve of defined speed driving drafting system 2 Draw 21, third roller 22, middle roller 24 and front roller 25.

Spinning valve 92 is configured to configure on the path for supplying compressed air from compressed air source to air spinning device 3 Solenoid valve.Spinning valve 92 allows hand over whether generate for fibre bundle 9 is twisted and spin in air spinning device 3 Convolution air stream.

First guiding device motor 93 is can to make the first guiding device 11 with its base end portion center of rotation to guide position Electric motor being rotated with position of readiness, can rotating forward and invert.

It is that yarn can be made to be detached from guiding device 14 to rotate to position of readiness and operating position that yarn, which is detached from guiding device motor 94, , the electric motor that can be rotated forward and invert.

Second guiding device motor 95 is can to make the second guiding device 12 with its base end portion center of rotation to operating position Electric motor being rotated with position of readiness, can rotating forward and invert.In the winding of package 70, the second guiding device 12 is located at figure 1 operating position shown in solid guides the traveling of spinning yarn 10 with third guiding device 13 together.It is aftermentioned connect yarn after Position of readiness shown in chain-dotted line of second guiding device 12 from Fig. 1 is set to be moved to operating position, thus, it is possible to by spinning yarn 10 It is again placed in yarn road.

Connecing yarn cam motor 96 is that can rotate the cam for illustrating omission for driving yarn splicing device 6 to have, Neng Gouzheng The electric motor for turning and inverting.What the cam made that yarn splicing device 6 has respectively connect yarn operating member (such as poly- yarn bar, presser bar, folder Tight portion and cutter etc.) movement.

Capturing guidance motor 97 is that the first capture guide device 15 and second can be made to capture guide device 16 to upper and lower turn Electric motor that is dynamic, can rotating forward and invert.Driving the first capture guidance dress can also be had respectively by capturing guidance motor 97 Set 15 electric motor and the electric motor of driving the second capture guide device 16.

Air injection valve 98 is configured to configure the road supplying compressed air from compressed air source to air jet system 61 Solenoid valve on diameter.Air injection valve 98, which allows hand over to supply and supply to the compressed air of air jet system 61, to be stopped.

Winding brake valve 99 is disposed on the road for supplying compressed air to executing agency appropriate (such as pneumatic cylinder) Solenoid valve on diameter, the executing agency are used to make arrestment mechanism (diagram is omitted) work of winding device 7.Wind 99 structure of brake valve Braking and brake release as the package 70 allowed hand in winding device 7.

Control unit 90 is electrically connected with above-mentioned each motor, can control the rotation and stopping or revolving speed etc. of each motor.Control Portion 90 processed is electrically connected with above-mentioned each valve, can control the opening and closing of each valve.Spinning yarn detection device 30, yarn monitoring device 4, Accumulation Yarn detection device 50 and Yarn detection device 60 are electrically connected with control unit 90, can be will test result and be exported respectively To control unit 90.

Then, illustrate that is carried out in the case where detecting yarn defect by yarn monitoring device 4 connects yarn.With initial reference to Fig. 5 to Fig. 9 To illustrate the process for connecing yarn carried out in the case where detecting that shortage falls into S.

In the case where detecting that shortage falls into S by yarn monitoring device 4, control unit 90 closes spinning valve 92 immediately, makes to lead The rotation for stretching motor 91 stops.By the stopping of spinning, as shown in figure 5, being located at upstream compared with accumulation Yarn detection device 50 The spinning yarn 10 of side is cut off because of the stopping of spinning.As a result, accumulation in yarn accumulation device 5 spinning yarn 10 it is upper It swims side and generates yarn ends A.

Control unit 90 no longer detects spinning yarn 10 from accumulation Yarn detection device 50 after closing spinning valve 92 Time point is to by maintaining the rotation of package 70 until providing winding time.That is, control unit 90 is maintained in the rotation that will be wrapped 70 Stop the rotation of the package 70 after stipulated time, so that the shortage that spinning yarn 10 includes falls into S and yarn accumulation roller 51 Compared to positioned at downstream side.Thereby, it is possible to make accumulation be wound up into package 70 in the normal yarn of yarn accumulation device 5, therefore can Reduce the amount of the end of a thread when removing short sunken S.By winding accumulation in yarn accumulation device 5 just with common winding speed Normal yarn, can shorten aftermentioned first low-speed rolling around time, the time for connecing the yarn period can be shortened.

Above-mentioned regulation winding time can the thickness of travel speed and spinning yarn 10 based on spinning yarn 10 etc. and fit Work as setting.Preferably, in the state that a small amount of spinning yarn 10 is wound in the reserving portion 51a of yarn accumulation roller 51, package 70 rotation stops completely.Thereby, it is possible to avoid yarn ends A from twining onto the device between yarn accumulation device 5 and winch spool 72.

It after spinning stops and is the time point warp that spinning yarn 10 is no longer detected from accumulation Yarn detection device 50 It crosses after regulation winding time, control unit 90 stops the rotation of winch spool motor 72a, opens winding brake valve 99 and makes to illustrate The arrestment mechanism of omission acts.The rotation of package 70 stops as a result,.

After the rotation of package 70 stops, control unit 90 stops the rotation of accumulation motor 52 (i.e. yarn accumulation roller 51) Only.Yarn accumulation roller 51 rotate during, yarn ends A due to centrifugal force the outer peripheral surface from yarn accumulation roller 51 slightly It is swung in the state of leaving.Therefore, by stopping the later timing that is rotated in of yarn accumulation roller 51, the yarn can be prevented Line end A is twined to accumulation in the thread layers of yarn accumulation roller 51.

Control unit 90 is during after spinning stops until the rotation of yarn accumulation roller 51 stops, appropriate Timing executes the cleanup action based on spinning jet nozzle.But it is also possible to omit cleanup action.

After cleanup action completion, as shown in fig. 6, control unit 90 rotates the first guiding device motor 93, so that first Guiding device 11 is moved to position of readiness (solid line).

At the same time or before this or later, control unit 90 makes to capture the guidance rotation of motor 97, so that first captures Guide device 15 is moved to the first yarn catching position (referring to the solid line of Fig. 6).

After the rotation of yarn accumulation roller 51 stops, control unit 90 opens yarn aspirating valve 54a and attracts yarn The top of device 54, which generates, attracts air stream.At the same time or after this, control unit 90 inverts accumulation motor 52, such as Fig. 2 It is shown to make 1.5~2 circle of the reversion of yarn accumulation roller 51.Spinning yarn 10 is slightly unwound from yarn accumulation roller 51 as a result, energy Yarn ends A is easily enough captured by yarn suction device 54.It is captured in this way, yarn ends A is attracted by yarn suction device 54, from And the first low-speed rolling carried out later around during can prevent the yarn ends A from twining to accumulation in yarn accumulation roller 51 Thread layers.

After the reversion of yarn accumulation roller 51 terminates, i.e. after yarn ends A is by the attraction capture of yarn suction device 54, Control unit 90 acts winch spool motor 72a, makes the winding of the spinning yarn 10 based on package 70 with the first low speed as shown in Figure 7 (such as 10~30m/min) starts.

In above-mentioned first low-speed rolling after beginning, control unit 90 is opening air injection valve 98 after the stipulated time, Compressed air is sprayed towards yarn road by air jet system 61.The above-mentioned stipulated time is filled with that can detect in yarn ends A from yarn 60 are set to suitably set in such a way that timing before starts based on the injection of the compressed air of air jet system 61.

By the first low-speed rolling of winding device 7 around accumulation is slowly rolled up in the spinning yarn 10 of yarn accumulation roller 51 It is around in package 70.Later, yarn ends A is drawn from yarn suction device 54.If yarn ends A is solved from yarn suction device 54 It puts, is then attracted as shown in Figure 7 by yarn trap 41.Then, by the first low-speed rolling of winding device 7 around continuation, yarn ends A Also it is drawn from yarn trap 41.In this way, since yarn ends A is downstream moved while being kept by stage, so can Yarn ends A is avoided to twine onto other devices.

When yarn ends A is drawn from yarn trap 41, yarn ends A becomes free state, therefore, as shown in figure 8, the yarn It holds A to be blown by air jet system 61 to the direction for leaving yarn road winged, and is hung on yarn limitation guiding device 62.

As shown in figure 8, since yarn ends A is hung on yarn limitation guiding device 62 and leaves from yarn road, so spinning yarn 10 It will not pass through from Yarn detection device 60.Yarn detection device 60, which detects in yarn road, does not have 10 this case of spinning yarn, and The detection signal for indicating no spinning yarn 10 is sent to control unit 90.Control unit 90 is received from Yarn detection device 60 Stop the rotation of package 70 when the detection signal.

In this way, can be immediately detected by using air jet system 61 yarn ends A from yarn accumulation device 5 from It opens and is drawn this case from yarn trap 41, can capture guide device 16 second should in the capture of the second yarn catching position In the state of yarn ends A, make the first low-speed rolling of winding device 7 around stopping.That is, yarn ends A can be prevented to be winding to package 70.Yarn ends A will not be twined in the thread layers of package 70 as a result, can easily capture the by the second capture guide device 16 Two yarns.

Later, the second yarn shown in solid that control unit 90 makes the second capture guide device 16 be moved to Fig. 8 captures position It sets and it is made to capture yarn ends A.After the second capture guide device 16 captures yarn ends A, control unit 90 closes air spray Valve 98 is penetrated, the injection of the compressed air based on air jet system 61 is stopped.

Then, the solid line that control unit 90 makes the second capture guide device 16 be moved to Fig. 9 while inverting package 70 Shown in connect yarn position.Yarn splicing device 6 is directed to by the second yarn that the second capture guide device 16 captures as a result,.

Also can replace, which is moved to the second capture guide device 16, connects yarn position, and makes the second capture guide device 16 temporarily And it is moved to position of readiness shown in the dotted line of Fig. 9, and move it to after the reversion of package 70 finishes and connect yarn position.It should Position of readiness can not be contacted and can be passed through from Yarn detection device 60 with the nozzle of yarn splicing device 6 etc. with spinning yarn 10 Mode suitably set.Spinning yarn 10 can be prevented to be suspended in yarn splicing device 6 in the reversion of package 70 as a result,.

As shown in figure 9, the guidance for capturing guide device 16 by second, spinning yarn 10 is logical from Yarn detection device 60 It crosses, so as to detect the presence of the spinning yarn 10 by Yarn detection device 60.

Based on the testing result of the Yarn detection device 60, it can easily be determined that and capture guide device 16 based on second Whether the capture of yarn ends A succeeds.Specifically, control unit 90 make the second capture guide device 16 be moved to connect yarn position it Afterwards, in the case where detecting spinning yarn 10 by Yarn detection device 60, it is judged to capturing guide device 16 based on second The capture success of second yarn, in the case where that can not detect spinning yarn 10 by Yarn detection device 60, is judged to being based on Second captures the capture failure of the second yarn of guide device 16.Control unit 90 is capturing the second of guide device 16 based on second Middle disconnecting yarn in the case where the capture failure of yarn.

In the successful situation of capture for the second yarn that control unit 90 is judged to capturing guide device 16 based on second, After the spinning yarn 10 for having unwound specific length from package 70, control unit 90 stops winch spool 72 (winch spool motor 72a) Reversion stops the reversion of package 70.Above-mentioned specific length is can remove the side that shortage falls into S by the second capture guide device 16 Thickness of the formula based on spinning yarn 10 or the speed reversal for being wrapped 70 etc. and suitably set.But not limited to this, for example, can also To monitor spinning yarn 10 by Yarn detection device 60, detecting what the sunken S of shortage had passed through by Yarn detection device 60 After situation, control unit 90 stops the reversion of package 70.

In this way, second captures guide device that will guide in the process to yarn splicing device 6 from the second yarn of package 70 16 shortage for including by the spinning yarn 10 being caught in fall into S and remove.Thus, it is no longer necessary to which separately setting removes the sunken S's of shortage Process, so as to shorten the time for connecing the yarn period.

After the reversion of package 70 stops, control unit 90 opens spinning valve 92 and makes going out based on air spinning device 3 Yarn starts, and rotates each roller of drafting system 2 to go out the corresponding revolving speed of yarn with this.

After detecting the spinning yarn 10 by going out yarn generation by spinning yarn detection device 30, when have passed through When providing yarn spinning time, control unit 90 makes the first capture guide device 15 be moved to the shown in solid of Fig. 9 to connect yarn position. Yarn splicing device 6 is directed to by the first yarn that the first capture guide device 15 captures as a result,.The regulation yarn spinning time It can be suitably set in such a way that the first capture guide device 15 can capture the first yarn.For example, can also constitute are as follows: first The yarn detection sensor that the inside setting diagram of guide device 15 is omitted is captured, and detects the in the yarn detection sensor The time point of one yarn keeps the first capture guide device 15 mobile.

Control unit 90 makes the second guiding device motor 95 work before the movement for starting above-mentioned first capture guide device 15, The second guiding device 12 to be moved to the position of readiness shown in solid of Fig. 9.

During the first capture guide device 15 is moved to from the first yarn catching position and connects yarn position, control unit 90 makes First guiding device 11 is moved to the guide position shown in solid of Fig. 9, at the same time or after this, returns the second guiding device 12 Be back to operating position shown in the chain-dotted line of Fig. 9, spinning yarn 10 is hung on yarn hooking member 53 as a result, spinning yarn 10 to The accumulation of yarn accumulation roller 51 starts.Control unit 90 starts the rotation of yarn accumulation roller 51 in timing appropriate, so that It is moved in the first capture guide device 15 and connects time point of yarn position and rotated with revolving speed corresponding with yarn out.

At the same time or after this, as shown in figure 9, control unit 90 makes yarn be detached from guiding device 14 from position of readiness (point Scribing line) turn to operating position (solid line).Spinning yarn 10 is detached from from the yarn hooking member 53 of yarn accumulation device 5 as a result, Accumulation is not attracted in yarn accumulation roller 51 but by the first capture guide device 15.

At the same time, control unit 90 starts the usual spinning of air spinning device 3, and makes each sieve of drafting system 2 Revolving speed rotation when drawing usually to spin.

After having begun to pass through the usual spinning time of regulation from the usual spinning based on air spinning device 3, control unit 90 So that yarn is detached from guiding device 14 and be back to position of readiness, makes the accumulation of the spinning yarn 10 carried out based on yarn accumulation device 5 again Secondary beginning.At the same time, start the yarn that connects based on yarn splicing device 6.

For connecing in yarn splicing device 6 after yarn completes, control unit 90 makes the second low-speed rolling in winding device 7 around beginning, And start the injection of the compressed air based on air jet system 61, judgement connects whether yarn succeeds.Second low-speed rolling is around being Refer to package 70 with the second low speed (such as 10~20m/min) just then by spinning yarn 10 with low-speed rolling around.

In the case where connecing yarn failure, due to the spinning yarn 10 of truncation state blown by air jet system 61 it is winged, so Spinning yarn 10 is detached from from Yarn detection device 60.Therefore, Yarn detection device 60, which detects in yarn road, does not have spinning yarn 10 This case, and will test signal and sent to control unit 90.In this case, control unit 90 is judged to connecing yarn failure, makes drawing-off Second low-speed rolling of the drawing-off movement of device 2, the spinning movement of air spinning device 3 and winding device 7 is around stopping.Then, such as Shown in Figure 13, control unit 90 makes the injection of the compressed air based on air jet system 61 continue the stipulated time.It is compressing During air continues injection, control unit 90 inverts winch spool 72 slightly and unwinds spinning yarn 10 from package 70, so that volume Spinning yarn 10 between winding apparatus 7 and yarn splicing device 6 increases.The above-mentioned stipulated time of compressed air is sprayed so that spinning can be eliminated The mode of the intrinsic torque of yarn yarn 10 is suitably set.Thereby, it is possible to the motion stability for connecing the yarn ends in yarn etc. after being allowed to.

After stipulated time warp, control unit 90 stops the movement of air jet system 61 for the time being, draws the second capture It leads device 16 and is moved to the second yarn catching position, and make to connect yarn and start again at.The is captured capturing guide device 16 by second During two yarns, act air jet system 61 intermittently.Between the time that air jet system 61 intermittently acts It is suitably set in a manner of maintaining the state that can capture the second yarn by the second capture guide device 16 every equal.Thereby, it is possible to Guide device 16 is captured by second and captures the second yarn, and can reduce the consumption of compressed air.

In the case where connecing the successful situation of yarn, spinning yarn 10 is not by the injection of the compressed air based on air jet system 61 It influences and is detected by Yarn detection device 60.In this case, control unit 90 is judged to connecing yarn success, makes winch spool motor 72a accelerates to common winding speed, starts again at the common winding based on winding device 7.

The spinning yarn 10 of specified amount comprising the sunken S of shortage is cut off by the cutter that yarn splicing device 6 has, and such as Fig. 9 It is shown to be attracted by the second capture guide device 16 and be removed.

Then, referring to Fig.1 0 to Figure 12 come be described in detail in the case where detecting long defect L by yarn monitoring device 4 into The capable process for connecing yarn.In the following description, only illustrate the movement different from the case where detecting shortage sunken S, and omit about The explanation of movement identical with the case where shortage falls into S is detected.

In the case where detecting long defect L by yarn monitoring device 4, control unit 90 closes spinning valve 92 immediately, and makes The rotation of drawing-off motor 91 stops.By the stopping of spinning, as shown in Figure 10, it is located at compared with accumulation Yarn detection device 50 upper The spinning yarn 10 for swimming side is cut off.Yarn is generated in the upstream side of the spinning yarn 10 of yarn accumulation device 5 in accumulation as a result, Hold C.

As shown in Figure 10, the timing early than detecting shortage sunken S the case where of control unit 90, the long defect L at least A part is by stopping the winding of winding device 7 in the state of 5 accumulation of yarn accumulation device.For example, control unit 90 can with stop Only spinning simultaneously stops the winding of winding device 7.In this case, due to since winding device 7 wind stopping to Time lag until winding stopping completely, can wind a degree of spinning yarn 10.But not limited to this, is also possible to control Portion 90 processed stops the winding of winding device 7 after stipulated time warp after closing spinning valve 92.

Here, preferably in long defect L wholly or largely by filling winding in the state of 5 accumulation of yarn accumulation device Set 7 winding stopping.Thereby, it is possible to avoid long defect L from being largely wound in package 70.In other words, in order to remove long defect L and The length of the spinning yarn 10 unwound from package 70 is shorter.Therefore, the time for connecing the yarn period can be shortened.

Moreover, the case where S sunken with shortage is identically, control unit 90 makes to store based on yarn after the rotation of package 70 stops The accumulation of the spinning yarn 10 of device 5 is stayed to stop.After the rotation of yarn accumulation roller 51 stops, control unit 90 inhales yarn The top of leading-in device 54, which generates, attracts air stream to capture yarn ends C to attract.At the same time or after this, control unit 90 makes to store It stays motor 52 to invert, makes 1.5~2 circle of the reversion of yarn accumulation roller 51 as shown in Figure 2.

At the same time or after this, as shown in figure 11, control unit 90 acts yarn splicing device 6, keeps in yarn splicing device 6 Cut off spinning yarn 10 using the cutter that yarn splicing device 6 has in the state of spinning yarn 10.Two yarns are generated as a result, Line end.In the following description, by the yarn ends of 5 side of yarn accumulation device, (accumulation is in the spinning yarn 10 of yarn accumulation device 5 The yarn ends in downstream side) it is known as yarn ends D, the yarn ends of 7 side of winding device (are wrapped in the spinning yarn 10 in package 70 Yarn ends) it is known as yarn ends E.

As shown in figure 11, yarn ends D is attracted by yarn trap 41 and is captured, and yarn ends E is kept by yarn splicing device 6.

Later, control unit 90 inverts yarn accumulation roller 51.At this point, the yarn ends that attract by yarn trap 41 of Figure 11 D is detached from shown in solid operating position movement of the guiding device 14 to Fig. 9 by yarn and is drawn from yarn trap 41.It is lacked comprising long The spinning yarn 10 for falling into L is unwound from yarn accumulation roller 51, and is attracted by yarn suction device 54 and removed.Even if from yarn Accumulation roller 51, which starts reversion, have passed through the stipulated time, and accumulation Yarn detection device 50 also continues to test the feelings of spinning yarn 10 Under condition, control unit 90 is judged as unwinding failure and middle disconnecting yarn.

At the same time or after this, as shown in the timing diagram of Figure 12, control unit 90 remains yarn ends in yarn splicing device 6 Start the injection of the compressed air based on air jet system 61 in the state of E.Moreover, in 61 jet pressure of air jet system During contracting air, control unit 90 makes to wind to make the relaxation between yarn splicing device 6 and winding device 7 of spinning yarn 10 Cylinder 72 slightly inverts to unwind a small amount of spinning yarn 10 from package 70.Thereby, it is possible to mitigate the tension of spinning yarn 10, energy Enough avoid tampering for spinning yarn 10.

Control unit 90 make after the injection of the compressed air based on air jet system 61 starts yarn splicing device 6 act and Discharge yarn ends E.If yarn ends E is released, it can be blown by air jet system 61 and fly and be suspended on yarn limitation guiding device 62 (referring to Fig. 8).

After the movement of yarn splicing device 6 discharges yarn ends E, as shown in figure 8, control unit 90 makes the second capture guide device 16 are moved to the second yarn catching position.As shown in figure 12, control unit 90 is caught in the second capture guide device 16 to the second yarn During catching position movement, stop air jet system 61 for the time being, reaches the second yarn in the second capture guide device 16 and catch Catch the injection that position starts again at the compressed air based on air jet system 61 later.It is appropriate fixed after blast injection The zero correction of Shi Jinhang Yarn detection device 60.The capture for the first yarn for capturing guide device 15 based on first, based on the The capture of second yarn of two capture guide devices 16, to the guidance of yarn splicing device 6, the movement such as connect yarn due to being detected with above-mentioned The case where short sunken S, is identical, so omitting the description.

Long defect L can also removed and carrying out the winding for starting again at spinning yarn 10 after connecing yarn.Alternatively, can also be with The case where sounding an alarm after removing long defect L, will produce long defect L notifies operating personnel.

As described above, the spinning frame of present embodiment have air spinning device 3, yarn accumulation roller 51, Winding device 7, yarn monitoring device 4 and control unit 90.Air spinning device 3 using convolution air stream to fibre bundle 9 twist come Generate spinning yarn 10.51 accumulation spinning yarn 10 of yarn accumulation roller.Winding device 7 winds accumulation in yarn accumulation roller 51 Spinning yarn 10 and formed package 70.The configuration of yarn monitoring device 4 air spinning device 3 and yarn accumulation roller 51 it Between, it is able to detect the long defect L and the sunken S of shortage of spinning yarn 10.Control unit 90 by yarn monitoring device 4 in spinning yarn 10 In detect long defect L in the case where, at least part accumulation of the long defect L in the state of yarn accumulation roller 51, Stop the rotation of package 70, to interrupt the winding of the spinning yarn 10 carried out based on winding device 7.

Thereby, it is possible to prevent long defect L to be wound in package 70, the length of the spinning yarn 10 unwound from package 70 is shorter , therefore the amount of the end of a thread can be reduced, and can also shorten the time for connecing the yarn period.Pass through the traveling in spinning yarn 10 Metastable position configures yarn monitoring device 4, can maintain the measurement accuracy of yarn monitoring device 4 higher.

The control unit 90 of the spinning frame of present embodiment is detecting shortage in spinning yarn 10 by yarn monitoring device 4 In the case where falling into S, in a manner of the downstream of the yarn accumulation roller 51 on the direction of travel for making the sunken S of shortage be located at spinning yarn 10 Stop the rotation of package 70.

Accumulation in the normal yarn of yarn accumulation roller 51 is winding to package 70 before detecting the sunken S of shortage as a result, Therefore, the amount that can be reduced the end of a thread in the case where removing shortage sunken S, can shorten the time for connecing the yarn period.

The control unit 90 of the spinning frame of present embodiment is being detected long lack by yarn monitoring device 4 in spinning yarn 10 It falls into or in the case that shortage is fallen into, the generation of the spinning yarn 10 based on air spinning device 3 is interrupted, makes to be wound in package 70 The yarn ends C (Figure 10) or yarn ends A (Fig. 5) of spinning yarn 10 are generated.

As a result, in the case where detecting the defect of yarn, the generation by interrupting spinning yarn 10 can be avoided spinning The unhelpful generation of yarn yarn 10.In addition, since spinning yarn 10 is cut-off by the stopping spinned, so without separately setting Set the device of cutting spinning yarn 10.Therefore, it is possible to realize the simplification of structure.

The spinning frame of present embodiment has configuration The yarn suction device 54 that long defect L is removed.

Thereby, it is possible to easily by accumulation in the long defect L removing of yarn accumulation roller 51.

In the spinning frame of present embodiment, yarn suction device 54 has hollow tube and yarn aspirating valve 54a.Hollow tube It is connect with negative pressure source.Yarn aspirating valve 54a in order to make the attraction air stream flowed in hollow tube by opening, and in order to cut It is disconnected to attract air stream and close.

Thereby, it is possible to remove long defect L using attraction air stream.In addition, can yarn aspirating valve 54a's be simple to use Structure, the movement and movement for substantially switching yarn suction device 54 stop.

The control unit 90 of the spinning frame of present embodiment is opening yarn after the rotation of yarn accumulation roller 51 stops While aspirating valve 54a or after opening yarn aspirating valve 54a, invert yarn accumulation roller 51.

It is easy to capture long defect L by yarn suction device 54 as a result, and the long defect L can be rapidly removed.

The spinning frame of present embodiment has the downstream side rotatably configured in yarn accumulation roller 51 and will spin The shortage that yarn 10 includes falls into S is removed second and captures guide device 16.

The timing in the downstream side for being configured at yarn accumulation roller 51 with the sunken S of shortage stops the rotation of package 70 as a result, In the case where, the shortage easily can be removed by the second capture guide device 16 and fall into S.

The second of the spinning frame of present embodiment captures guide device 16 and is capturing the spinning yarn 10 from package 70 simultaneously It directs it in the process of yarn splicing device 6, the shortage for including by spinning yarn 10 falls into S and removes.

As a result, since the process for removing the sunken S of shortage can not separately be arranged, so the time for connecing the yarn period can be shortened. In addition, guide device 16 can be captured as the device for guiding spinning yarn 10 to yarn splicing device 6 by second.Therefore, Neng Goumou Ask the simplification of structure.

The control unit 90 of the spinning frame of present embodiment makes yarn accumulation roller 51 after the rotation of package 70 stops Rotation stops.

Rotation is being winding in the yarn ends A (C) for the spinning yarn 10 that the upstream side of yarn accumulation roller 51 is cut off Yarn accumulation roller 51 after, maintaining the state from the outer peripheral surface of yarn accumulation roller 51 slightly away due to centrifugal force It slightly swings simultaneously.By making this state continue longer time, it can prevent the yarn ends A (C) from twining to accumulation in yarn The thread layers of accumulation roller 51.

The spinning frame of present embodiment, which has, detects the presence of accumulation in the accumulation of the spinning yarn 10 of yarn accumulation roller 51 Yarn detection device 50.Control unit 90 is when yarn monitoring device 4 detects that shortage falls into S, by accumulation Yarn detection device 50 It detects on yarn accumulation roller 51 after non-accumulation spinning yarn 10, separates the time difference (separating certain time) and make package 70 Rotation stop.

As a result, when the rotation for being wrapped 70 stops, the sunken S of shortage can be made to be located at the downstream of yarn accumulation roller 51.

The spinning frame of present embodiment has Yarn detection device 60 and air jet system 61.Yarn detection device 60 is matched Set between yarn accumulation roller 51 and winding device 7, and detect spinning yarn 10 traveling yarn road in whether there is or not the spinning yarns 10.Air jet system 61 configures between yarn accumulation roller 51 and winding device 7, and sprays compressed air to yarn road.Control Portion 90 processed makes package 70 along the winding of winding spinning yarn 10 on one side after the spinning based on air spinning device 3 is interrupted Direction rotates makes the air based on air jet system 61 spray progress on one side.Control unit 90 is in air jet system 61 to yarn road When spraying compressed air, if detecting that spinning yarn 10 is not present in yarn road by Yarn detection device 60, make package 70 Rotation stops.

Thereby, it is possible to rapidly and be detected positively the spinning yarn 10 being cut off in the upstream side of yarn accumulation roller 51 Yarn ends A leaves this case from yarn accumulation roller 51.

It is 70mm or more 110mm reserving portion below that the yarn accumulation roller 51 of the spinning frame of present embodiment, which has diameter, 51a。

Thereby, it is possible to stop the winding of package 70 in the state that long defect L certainly remains on yarn accumulation roller 51, It can shorten and handle the time required for removing long defect L.

The yarn accumulation roller 51 of the spinning frame of present embodiment is capable of the spinning yarn 10 of accumulation 10m or more.

It, also can be in the state that long defect L remains on yarn accumulation roller 51 even the long defect L of 10m or more as a result, Stop the winding of package 70.

The preferred embodiment of the present invention is illustrated above, but above structure for example can be as described below Change.

The movement of each section shown in the timing diagram of Figure 12 can be implemented in the case where detecting that shortage falls into S.

The movement in each portion shown in the timing diagram of Figure 12 can also only be implemented in the case where connecing yarn failure.

In the case where being judged to connecing yarn failure, if not continuing the movement of air jet system 61, it will be able in package 70 Reversion in make the motion stability of yarn ends A (E), then keep yarn ends A such as the clip that can also omit by diagram (E).Alternatively, can also the continuation without the movement of air jet system 61 and the yarn ends A (E) based on clip etc. guarantor It holds.

Air jet system 61 and yarn limitation guiding device 62 can not also configure on main boot device 64, but configure It in the upstream side compared with winch spool 72 and is that can capture the other position that guide device 16 captures the second yarn by second It sets.

Air jet system 61 can also only have a nozzle.

Also can replace yarn suction device 54 and by yarn trap 41 by comprising long defect L slave yarn ends D to yarn It holds the spinning yarn 10 of C to attract to remove.In this case, control unit 90 closes yarn aspirating valve 54a and makes yarn suction device 54 movement stops, and rotates forward yarn accumulation roller 51.Also it can be omitted yarn trap 41.

Air spinning device 3 also can replace above structure and have each other round about to a pair of fibre bundle twisting Air nozzle.Open-end spinning device (rotary spinning apparatus) can be set also to replace 2 He of drafting system in spinning unit 100 Air spinning device 3.

Delivery roller pair can also be set between air spinning device 3 and yarn accumulation device 5, and by the delivery roller It is drawn to by spinning yarn 10 from air spinning device 3.In this case, a roller of delivery roller centering is relative to other The roller of spinning unit 100 is rotated independently driving, can individually rotate driving in the spinning unit 100 for carrying out connecing yarn The roller.When the winding for being wrapped 70 interrupts, which synchronously stops rotating with package 70.

Also device of splicer or knotter etc. be can replace and so that spinning yarn 10 is become continuous state by connector.It is so-called to connect Head refers to following methods: making to send air spinning device 3 back to and then secondary start based on from the spinning yarn 10 of package 70 is counter The drawing-off of drafting system 2 and spinning based on air spinning device 3, so that spinning yarn 10 be made to become continuous state.

In the case where detecting that shortage falls into S, the winding for stopping package 70 can be also replaced, and make the winding of the package 70 It is decelerated to the first low speed, slowly winds generated yarn ends A.In this case, yarn accumulation roller 51 both can be same as before Continuing its rotation can also slow down, or can also stop simultaneously inverting 1.5~2 circles as described above for the time being.

It can also be other than accumulation Yarn detection device 50, in the base end side of the reserving portion 51a of yarn accumulation roller 51 (upstream side that spinning yarn 10 is advanced) also sets up the second accumulation Yarn detection device.Yarn accumulation sieve will be wrapped in as a result, In the case where drawing the unwinding of spinning yarn 10 comprising long defect L on 51 and attracting removing by yarn suction device 54, Neng Gouji The unwinding success or not of the spinning yarn 10 is more accurately determined in the testing result of the second accumulation Yarn detection device.Except this it Outside, some or all of detection operation of the accumulation Yarn detection device 50 when connecing yarn can be replaced, and carry out based on this The detection operation of two accumulation Yarn detection devices.That is, control unit 90 is able to use the second accumulation Yarn detection device when connecing yarn Testing result come replace accumulation Yarn detection device 50 testing result part or all.

In spinning unit 100, the spinning yarn 10 that can also be supplied in the height direction from upside is rolled up in downside Around mode configure each device.

Yarn splicing device 6 can also be set on the Mobile workbench that can be movably arranged relative to multiple spinning units 100. In this configuration, will be wrapped the spinning yarn between 70 and yarn accumulation device 5 10 cut off in the case where, spinning yarn 10 by Cutter set on the cutter of Mobile workbench or the cutter of yarn splicing device 6 or in each spinning unit 100 is cut It is disconnected.

The winch spool 72 of multiple spinning units 100 can be driven by a drive motor.In the winding for interrupting package 70 When, package 70 can also be made far from winch spool 72, and stop the rotation of package 70 by the arrestment mechanism of diagram omission.It is rolling up It fills after having cut off spinning yarn 10 between 70 and yarn accumulation device 5, it can also be by contacting package 70 with winch spool 72 And the spinning yarn 10 being connected with package 70 is wound in package 70.Later, make package 70 again far from winding in order to connect yarn Cylinder 72.

For avoiding spinning yarn 10 from being suspended to yarn hooking member when removing spinning yarn 10 from yarn accumulation roller 51 The structure that structure on 53 is not limited to the above embodiment.For example, it is also possible to which it is de- that yarn is arranged in yarn accumulation device 5 From bar and the yarn is made to be detached from bar movement, spinning yarn 10 is thus avoided to be suspended in yarn hooking member 53.
