Below the forming process of the yarn Y of the weaving mechanism that is made of the textile apparatus with said structure is summarized.
Draw from bar tube 2, the fibre bundle 1 of supplying with drafting system D is by drafting system D, after total stretch ratio according to the rules carries out drawing-off, under the effect of following air flow, enter entrance hole 16a, this air flow refers near the attraction air flow the entrance hole 16a of the fiber importing member 16 that produces under the effect of the injection air that the nozzle bore 17d from nozzle arrangement 17 sprays, then, this fibre bundle 1 is given along feeding on every side of pin 16b, enter in the spatial portion 17 that is formed in the nozzle arrangement 17, at the leading section 19a of the hollow guiding body of rod 19 and the weaving chamber 17c1 between the fiber importing parts 16.
Constituting the fiber that is drawn into the fibre bundle 1 in the weaving chamber 17c1 sprays from nozzle bore 17d, near the leading section 19a of the hollow guiding body of rod 19, be subjected to the effect of the revolution air-flow of high speed rotary, with when fibre bundle 1 separates, part counter-rotating is wound in the periphery of the leading section 19a of the hollow guiding body of rod 19, in addition, whirling around the yarn Y in being in forming process is wound in its periphery simultaneously, along the direction twisting of revolution air-flow.In addition, propagate towards the direction of preliminary roller 6 by the part twisting meeting that the revolution air-flow hangs up, still, because this propagation is subjected to the prevention of pin 16b, so can not twist by above-mentioned twisting from the fibre bundle 1 of preliminary roller 6 derivation.Form actual trueing add successively by the revolution air-flow fiber of twisting and twist with the fingers the yarn Y of shape, this yarn Y is by core fibre, and the winding fiber that is wound on the core fibre forms, and this fiber is discharged from yarn outlet 19g by the yarn path 19d of the hollow guiding body of rod 19.Like this, in the forming process of common yarn Y, compressed air is from the compressed air supply source, through managing 21 and connecting elements 20, do not feed to the internal air passageways 19b of the hollow guiding body of rod 19, therefore, compressed air is not fed to the inside of yarn path 19d from pilot jet 19e.
In common textile state, yarn path 19d by the hollow guiding body of rod 19, the yarn Y that discharges from yarn outlet 19g is by niproll 7a that constitutes yarn feeding member 7 and transfer roller 7b clamping, feed along package 10 directions, then, when carrying out the network strand, contact, be wound in the rotating package 10 with friction roller 13 by network strand guide 14.
Joint operation to Weaving device with above-mentioned scheme is described below.
When the weaving beginning, or when producing broken end, back roller 3 and the 3rd roller 4 are stopped, therefore, fibre bundle 1 is cut off at the 3rd roller 4 that has stopped with between the 2nd roller 5 of rotation usually, and the leading section of fibre bundle 1 is controlled by the 3rd roller 4 that stops.When the joint operation, by driving back roller and the 3rd roller 4 once more, send fibre bundle 1, through at the 2nd roller 5 and the preliminary roller 6 that are driven in rotation at ordinary times, supply with weaving member S.Begin the driving of the drafting system D that stopped once more, and, begin compressed-air actuated injection from the nozzle bore 17d of nozzle arrangement 17 and the pilot jet 19e of the hollow guiding body of rod 19.That is, when the joint operation,, spray compressed air, and from the compressed air supply source, through pipe 21 and connector 20, the internal air passageways 19b to the hollow guiding body of rod 19 supplies with compressed air from the nozzle bore 17d of nozzle arrangement 17.So,,, spray compressed air also to the inside of path 19d from pilot jet 19e.
Because the compressed air that sprays from the nozzle bore 17d of nozzle arrangement 17 is in the rotating while, feeding direction along fibre bundle 1 flows, import the fibre bundle 1 of entrance hole 16a of parts 16 under the effect of this revolution air-flow so send into fiber, be in false twisting state slowly, pass through pin 16b simultaneously, feed near the leading section 19a of the hollow guiding body of rod 19.In addition, the compressed air that sprays from pilot jet 19e is along the yarn path 19d that is formed at the hollow guiding body of rod 19, when forming the revolution air-flow, realize flowing, and near the opening 19h that is formed at this hollow guiding body of rod 19 leading section 19a, produce the air flow that attracts direction (direction) towards the inside of the hollow guiding body of rod 19.Thus, serially, fibre bundle 1 is pulled into the inside of the yarn path 19d of the hollow guiding body of rod 19.
The fibre bundle 1 of feeding near the false twisting state the opening 19h that is formed at this hollow guiding body of rod 19 leading section 19a is drawn onto among the yarn path 19d from opening 19h.Then, this fibre bundle 1 is exposed to the revolution gas that is produced by the compressed air that sprays from pilot jet 19e in the inside of yarn path 19d.At the compressed air that sprays by nozzle bore 17d from nozzle arrangement 17, the revolution air-flow that produces in the inside of weaving chamber 17c1, and pass through from the compressed air of the pilot jet 19e injection of this hollow guiding body of rod 19, under the effect of the revolution air-flow that produces in the inside of the yarn path 19d of this hollow guiding body of rod 19, the fibre bundle 1 of false twisting state is woven into the fibrous yarn of hanking tie (yarn of hanking tie), simultaneously, the yarn outlet 19g from hollow guide post body 19 discharges.
As above-mentioned, behind broken end, drive back roller 3 and the 3rd roller 4 once more, begin feeding of fibre bundle 1 once more, by the compressed air that sprays from the nozzle bore 17d of nozzle arrangement 17, and from the compressed air that the pilot jet 19e that is formed on the hollow guiding body of rod 19 sprays, the fibrous yarn of hanking tie is weaved, this state is called " drawing the yarn weaving ".
Above-mentioned draw yarn weaving after, through appropriate time, then, stop from compressed air source, internal air passageways 19e to the hollow guiding body of rod 19, supply with compressed air, stop from pilot jet 19e, to the inside of yarn path 19d, spray compressed air, thus, the revolution air-flow in the hollow guiding body of rod 19 disappears, and turns back to common textile state.
As above-mentioned, the yarn Y that begins once more to weave and form is arranged on the locational joint chassis A that stops at the U of weaving mechanism that carries out the joint operation, and follow revolution towards top that can rotating known attraction nozzle a1, be attracted to the hollow guiding body of rod 19 yarn outlet 19g near, then, follow revolution, be sent among the known piecing devices a2 that is arranged on the joint chassis A to the top that attracts nozzle a1.By attracting nozzle a1, be sent in the process of piecing devices a2, yarn Y is by niproll 7a that constitutes yarn feeding member 7 and transfer roller 7b clamping.On the other hand, the terminal part that is rolled into the yarn Y in the package 10 attracts by the known attraction mouthful a3 that is arranged on the joint chassis A, then, follows the revolution to the top that attracts mouthful a3, is sent among the above-mentioned piecing devices a2.Then, be fed to the piecing devices c2 by weaving member S yarn Y that forms and the yarn Y that draws from package 10, then, drive sub device c2 carries out joint to these two yarn Y and handles the joint end of job.The unnecessary yarn Y that forms in this joint operation is stored on lax pipe (the slack tube) 8 as known temporarily.
Below by Fig. 2 and Fig. 4, counter extensioin device D, weaving member S, yarn feeding member 7, action or the drive controlling of yarn clearer 9 and coiling member W etc. are described.
M1 represents single hammer CD-ROM drive motor, this independent spindle CD-ROM drive motor is provided with at each weaving U of mechanism, it is used to drive back roller 3 and the 3rd roller 4, this motor is provided with in the following manner, this mode is: be installed on the back on the roller 3 pulley 3a and be installed on pulley 4a on the 3rd roller 4, and be installed between the pulley m1 on the output shaft of independent spindle CD-ROM drive motor M1, open and be provided with endless belt b1, thus, rotation drives back roller 3 and the 3rd roller 4.Spindle CD-ROM drive motor M1 constitutes in the following manner separately, and this mode is: it,, is controlled rotary speed at each weaving mechanism by the central controller C1 as master controller by motor driver MD1.Here, spindle CD-ROM drive motor M1 also can adopt stepper motor separately.Thus, need not the rotation detector of encoder etc., can carry out the control of open loop.
M2 represents shared motor, this shared motor is by variable-speed motor T1, rotation drives the 2nd roller 5, and rotation drives preliminary roller 6 respectively, constitute the transfer roller 7b and the friction roller 13 of feeding member 7,, 1 shared motor M2 is set in the inside of engine housing E1, this motor constitutes a plurality of weaving mechanism of Weaving device relatively, is shared.This shared motor M2 constitutes in the following manner, and this mode is: it, is controlled by the set central controller C2 as master controller in the inside of engine housing E1 by motor driver MD2.In addition, constitute in the following manner, this mode is: by the instruction of this central controller C2, by motor driver MD2, realize in the situation of acceleration and deceleration of shared motor M2, at the state that keeps predetermined rotational speed, with the method for synchronization to the 2nd roller 5, preliminary roller 6, yarn feeding member 7 and friction roller 13 are controlled.Thus, can be by making the rotary speed of each different between back roller 3, the 3 rollers 4 and the 2nd roller 5 and the preliminary roller 6, the drawing-off of the total stretch ratio of stipulating.
But, the diameter of formed yarn (number) is mainly by discharging from preliminary roller 6, supplying with the fibre weight of weaving member S determines, yet, in the Weaving device in the past,, will form the time identical fibre weight of operation with common yarn even in the joint operation of Weaving device, from drafting system D, supply with weaving member S.But drawing yarn when weaving in carrying out the joint operation is not suitable for if supply with the amount of the fibre bundle 1 of weaving member S, then draws yarn weaving failure.Such as, in the process of the spun yarn Y that forms less number, in the occasion that produces broken end, supply with weaving member S if will form the identical fibre weight of operation, carry out the above-mentioned yarn weaving of drawing, then because fibre weight is few with the yarn of common less number, according to the weaving condition, in the forming process of the yarn of hanking tie of drawing yarn when weaving, can't satisfy the fiber necessary fibre weight of hanking tie, draw the formation failure of the yarn in the yarn weaving.Its reason is: such as, when drawing the yarn weaving with high speed, the time that fiber is exposed in the revolution air-flow is shorter, and owing to reason as described above, be difficult to obtain hanking tie of sufficient fiber, do not have the intensity in the yarn guiding downstream that prevention will generate.Otherwise, in the process that produces big number, under the situation that produces broken end, supply with fibrous structures S if the identical fibre weight of operation will be formed with the common yarn than big number, carrying out the above-mentioned yarn of drawing weaves, then fibre weight is too much, and fiber is jammed in the opening 19h of the hollow guiding body of rod 19 of weaving member S, draws the formation failure of the yarn of yarn weaving.
Below the rotary speed and Fig. 5 of time relation of main independent spindle CD-ROM drive motor M1 during by presentation graphs 4 and joint operation, to making above-mentioned success rate raising usefulness of drawing the yarn weaving, the joint operation of embodiments of the invention is described.
Among the yarn Y that is to have generated, exist the thicker part of slubbing etc. to divide or under the situation of the defect part of thin part etc., this defect part detects by yarn clearer 9, passes through cutter, the yarn Y of detected defect part is cut off, and the yarn Y of package 10 1 sides of having cut off is wound in the package 10., be input among the central controller C1 as shown in Figure 4 by the yarn defect part detection signal of yarn clearer 9.According to this yarn defect part detection signal, by motor driver MD1, by central controller C1, the driving of independent spindle CD-ROM drive motor M1 is stopped, at this moment, the rotation of back roller 3 and the 3rd roller 4 is stopped, between the 2nd roller 5 and the 3rd roller 4 of often rotation, fibre bundle 1 is cut off (time T 1 of Fig. 5).The fibre bundle of sending from the 2nd roller 5 and the preliminary roller 6 of frequent rotation 1 is still supplied with the weaving member S driving, and forms yarn Y, and formed yarn Y attracted to the not shown pipe of the positive upstream side that is arranged in cutter, with its removal.Then, stop to spray compressed air, stop the action of member S of weaving from the nozzle bore 17d that is formed on the nozzle arrangement 17 that constitutes weaving member S, and make package 10 from friction roller 13 away from, stop the rotation of package 10.
Then, carrying out the above-mentioned yarn of drawing weaves, but, such as, in the process of the yarn Y that forms less number, in the occasion that produces broken end, if supply with the yarn of common less number and form the identical fibre weight of operation, carry out the above-mentioned yarn of drawing and weave, then because the fibre weight of supply weaving member S is few, so have the situation that the yarn weaving is failed of drawing, thus, in the present embodiment, when beginning to weave once more, make from central controller C1, by motor driver MD1, speed when the rotary speed that makes rotation drive the independent spindle CD-ROM drive motor M1 of back roller 3 and the 3rd roller 4 is higher than common weaving reduces the total stretch ratio of drafting system D, the fibre weight of the weaving member S that increases supply.Its reason is: in common weaving, the rotary speed of the 2nd roller 5 is higher than the rotary speed of back roller 3, the 3 rollers 4, and the rotary speed of preliminary roller 6 is higher than the rotary speed of the 2nd roller 5.Particularly, the 2nd roller 5 is bigger than other with the rotary speed difference of preliminary roller 6.
The fibre bundle 1 that its front end is kept by the 3rd roller 4 that stops, drive back roller 3 and the 3rd roller 4 once more by instruction from central controller C1, be sent (time T 2 among Fig. 5) with this, as above-mentioned, by instruction, from common textile state from central controller C1, to make back roller 3 and 4 rotations of the 3rd roller at a high speed, reduce the total stretch ratio of drafting system D,, will supply with weaving member S (time T 3 among Fig. 5) than the fiber that common yarn forming process is Duoed through the 2nd roller 5 and preliminary roller 6.Basically the driving with the drafting system D that has stopped beginning simultaneously once more, once more from being formed at the nozzle bore 17d on the nozzle arrangement 17 that constitutes weaving member S, spray compressed air, and from being formed at the pilot jet 19e on the hollow guiding body of rod 19, spray compressed air, carry out the yarn weaving of drawing as described above.Thus, central controller C1 has played the effect that fiber supply of for a change drawing yarn when weaving and unit interval between the textile state usually and the fiber supply controlling organization that total stretch ratio is used and total stretch ratio change controlling organization.
By drawing the yarn outlet 19g discharge of yarn Y from hollow guide post body 19 that the yarn weaving forms, and by upward revolution and be positioned near the outlet 19e, attracted among the attraction nozzle a1 that is arranged at joint chassis A place, yarn is captured (time T 4 among Fig. 5).Then, follow and attract the revolution of nozzle a1 towards the below, the yarn Y that is attracted nozzle a1 attraction and captures is sent among the piecing devices a2 that is arranged among the joint chassis A, and by attracting nozzle a1, it is sent in the process of piecing devices a2, yarn Y is by constituting niproll 7a and the transfer roller 7b clamping in the yarn feeding member 7, and beginning yarn Y feeds, and carries out stable the sending (time T 5 among Fig. 5) of yarn Y.
In addition, the yarn Y of above-mentioned attraction nozzle a1 to piecing devices a2 send into operation in, make the air entry that is arranged at the attraction nozzle a3 on the identical joint chassis A, the package 10 that coiling direction opposite direction approaching and by not shown reverse roll rotates, attraction is involved in the yarn Y of package 10, and air entry a3 is turned round upward, yarn Y is sent into piecing devices a2.Then, will be sent to the piecing devices a with the yarn Y that draws from package 10 by the yarn Y of weaving member S formation, then, drive sub device a2 carries out joint to two yarn Y and handles, and adopts the joint end of job (time T 8 among Fig. 5) of piecing devices a2.In addition, the unnecessary yarn Y in the joint operation is stored in the above-mentioned lax pipe 8 provisionally.In addition, because will be discarded in the joint operation of piecing devices a2 according to the thicker yarn part that the total stretch ratio that has changed forms, so so thicker yarn part is not rolled in the package 10.
Above-mentioned drawing in the yarn fabrication processes, identical with at ordinary times fabrication processes, by the 2nd roller 5 that shared motor M2 is driven in rotation, preliminary roller 6, yarn feeding member 7 and friction roller 13 are controlled according to synchronous mode.
Above-mentioned drawing in the yarn fabrication processes, turn back to the moment of common total stretch ratio as the total stretch ratio that will change, in beginning by feeding yarn feeding power (time T 5 of Fig. 5) that member 7 provides yarn Y afterwards as yarn feeding device, particularly, finish draw yarn weaving (time T 6 among Fig. 5) after, preferably the total stretch ratio that will change turns back to common draw ratio.Thus, be in stable yarn feeding state by yarn feeding member 7, number is changed, can more spun loose thread passed out to the downstream.Between above-mentioned time T 2 and time T 6, draw the yarn weaving, then,, stop from pilot jet 19e in time T 6, injection air begins the weaving of true sth. made by twisting shape at ordinary times once more.In addition, for the moment that whether arrives the yarn feeding power that the yarn of yarn feeding member 7 Y is provided, when central controller C1 detection begins from drawing the yarn weaving, how long passed through, thus, according to this detection, by motor driver MD1, rotation with independent spindle hammer CD-ROM drive motor M1 turns back to the rotary speed (time T 7 of Fig. 5) in the common yarn forming process.In addition, in the moment for the time T 7 of determining Fig. 5, also can in attracting nozzle a1, the yarn detecting sensor be set, so that the power of feeding that replaces central controller C1 to detect the yarn Y of above-mentioned yarn feeding member 7 provides beginning.Thus, can more positively detect and draw yarn weaving, and the success of capturing by the spun yarn of weaving.In addition, also can constitute in the following manner, this mode is: central controller C1 does not carry out the detection of above-mentioned elapsed-time standards, when drawing the yarn weaving, near the attraction nozzle a1 that is positioned at the yarn outlet 19g attracts to capture the yarn Y that discharges from the yarn outlet 19g of hollow guide post body 19, then, make this attractions nozzle a1 towards below moment of rotating, or, the total stretch ratio that has changed is turned back to common total stretch ratio after this.By such formation, can shorten the thicker yarn part (between the time T 3～time T 7 among Fig. 5) that forms based on the total stretch ratio that has changed as much as possible, so thicker yarn part is not exclusively discarded, and is used for joint, can prevent to be involved in the package 10.
In addition, in common yarn forming process, when the yarn Y to bigger number weaves, in the occasion that produces broken end, if identical fibre weight when supplying with the yarn formation operation with common bigger number, carrying out the above-mentioned yarn of drawing weaves, then because the fibre weight of supply weaving member S is more, so fiber is jammed in the opening 19h of the hollow guiding body of rod 19 that constitutes weaving member S, has the situation of drawing yarn weaving failure, thus, in such occasion, the weaving begin once more the time, from central controller C1, by motor driver MD1, reduce the rotary speed of independent spindle CD-ROM drive motor M1, thus, improve the total stretch ratio of drafting system D, reduce the fibre weight of supplying with weaving member S.Except reducing the fibre weight of supplying with weaving member S, because identical with the above embodiments, the Therefore, omited is to its specific descriptions.
As above-mentioned, when drawing the yarn weaving, the back roller 3 of formation drafting system D and the rotary speed of the 3rd roller 4 are controlled, change the total stretch ratio of drafting system D, thus, suitably adjust the fibre weight of supplying with weaving member S, thus, can improve the success rate of drawing the yarn weaving.
In addition, owing to constitute in the following manner, this mode is: by the rotary speed of preliminary roller 6 not being controlled, and the rotary speed of back roller 3 and the 3rd roller 4 is controlled, changed total stretch ratio.So the speed of guide does not change,, the success rate of drawing the yarn weaving is improved even under the yarn guiding speed condition with higher when weaving usually.Needn't follow the change of yarn guiding speed, change the 2nd roller 5, preliminary roller 6, the rotary speed of yarn feeding member 7 and friction roller 13, that is, and the rotary speed of the shared motor M2 of Synchronization Control.Therefore, in stable status, can draw the yarn weaving, the control of Weaving device can be simplified.
In the above-described embodiment, provide following example, wherein, when drawing the yarn weaving, by the instruction of central controller C1, change the rotary speed that rotation drives the independent spindle CD-ROM drive motor M1 of back roller 3 and the 3rd roller 4, still, also can such formation, that is, the shared motor M2 of the inside by being arranged at engine case E1, rotation drives back roller 3 and the 3rd roller 4, by independent spindle CD-ROM drive motor M1, rotation drives preliminary roller 6.In this occasion, instruction by central controller C1, improve the rotary speed of independent spindle CD-ROM drive motor M1, improve the rotary speed of preliminary roller 6, thus, can improve the total stretch ratio of drafting system D, in addition, in contrast, by reducing the rotary speed of independent spindle CD-ROM drive motor M1, reduce the rotary speed of preliminary roller 6, can reduce the total stretch ratio of drafting system D.Its reason is: in weaving usually, the rotary speed of the 2nd roller 5 is higher than the rotary speed of back roller 3, the 3 rollers 4, and the rotary speed of preliminary roller 6 is higher than the rotary speed of the 2nd roller 5.Particularly, the 2nd roller 5 is set to bigger than other difference with the rotary speed difference of preliminary roller 6.
Thus, particularly when the yarn Y to less number weaves, in drawing the yarn weaving, in the rotary speed that reduces independent spindle rotation drive motor M1, reduce the occasion of the total stretch ratio of drafting system D, can make the number of drawing the yarn weaving higher, can reduce yarn guiding speed, so can more positively make the revolution air-flow of pilot jet 19e act on fibre bundle, can further improve the success rate of drawing the yarn weaving.
