Drafting system 5 makes the fineness degree of this sliver F uniform by drawing-off sliver F。As in figure 2 it is shown, drafting system 5 along sliver F direction of feed mainly by rear roller to the 51, the 3rd roller to 52, middle roller to 53, front roller to 54 these four groups of drawing rollers to constituting。Additionally, the arrow shown in figure represents the direction of feed of sliver F。
Four groups of drawing rollers are made up of bottom roll 51A, 52A, 53A, 54A and top roller 51B, 52B, 53B, 54B respectively to 51,52,53,54。Constituting zone circle 53C, 53C of wrapped around leather or synthetic rubber on middle roller bottom roll 53A and top roller 53B to 53。
Bottom roll 51A, 52A, 53A, 54A are rotated to equidirectional by not shown driving device。Top roller 51B, 52B, 53B, 54B rotate to equidirectional because of the rotation of bottom roll 51A, 52A, 53A, 54A drivenly。Each drawing rollers to 51,52,53,54 the direction of feed rotary speed being configured to along sliver F accelerate successively。
By such structure, the sliver F that drafted roller holds 51,52,53,54 every time by each drawing rollers to 51,52,53,54 time feed speed increase, thus adjacent drawing rollers between drafted。So, drafting system 5 can make the fineness degree of this sliver F uniform by sliver F is carried out drawing-off。
Air spinning device 6 manufactures spinning yarn Y by drafted sliver F is twisted。As it is shown on figure 3, air spinning device 6 is mainly made up of fibre guide part 61, spindle 62, nozzle body 63。Blacking arrow shown in figure represents the direction of feed of sliver F and spinning yarn Y。Hollow arrow shown in figure represents the flow direction of the air supplied。Air spinning device 6 shown in Fig. 3 is existing air spinning device, is not air spinning device 6A, 6B involved by embodiments of the present invention。
Fibre guide part 61 is the parts of the part constituting spinning room SC。The fibre guide part 61 sliver F by the drawing-off of drafted device 5 guides to spinning room SC。Illustrating, fibre guide part 61 guides sliver F by the fiber lead-in path 61g connected with spinning room SC to this spinning room SC。Being provided with pin 61n in the way of projecting to the inside of spinning room SC in fibre guide part 61, sliver F is directed along this pin 61n。
Spindle 62 is the parts of the part constituting spinning room SC。The fiber of the spinning yarn Y being twisted in the spinning room SC spindle 62 by connecting with spinning room SC is sent to the yarn direction of travel downstream of air spinning device 6 by path 62s。
Nozzle body 63 is the parts of the part constituting spinning room SC。Nozzle body 63 is formed the multiple airport 63a connected with spinning room SC。The air come from not shown air force feed device force feed is fed into spinning room SC by airport 63a。Additionally, each airport 63a being located at nozzle body 63 connects into so that flow up in mutually the same side centered by the central shaft of spinning room SC from the air of each airport 63a ejection。Thus, air spinning device 6 can produce the swirling eddy (hollow arrow with reference in figure) of air in the inside of this spinning room SC。
Further describe spinning room SC。Spinning room SC is the space defined by fibre guide part 61, spindle 62, nozzle body 63。Specifically, spinning room SC is by relative to the spindle 62 of the through hole 63p of the roughly conical shape being located in nozzle body 63 roughly conical shape inserted from a side be arranged on the space that the fibre guide part 61 of the opposing party is defined。The shape of through hole 63p is not limited to roughly conical shape as shown in Figure 3, it is also possible to be generally cylindrical shaped etc.。It is to say, as long as swirling eddy can be produced in spinning room SC well, the shape of through hole 63p is not limited to specific shape。
Spinning room SC is divided into: the space S C1 constituted between fibre guide part 61 and the spindle 62 and space S C2 constituted between spindle 62 and nozzle body 63。In space S C1, the rearward end constituting each fiber of sliver F is reversed by swirling eddy (with reference to double dot dash line)。In space S C2, the rearward end through reversion constituting each fiber of sliver F rotates (with reference to double dot dash line in figure) by swirling eddy。
By such structure, reversed in spinning room SC and rotated to fiber along pin 61n by the rearward end of the path 62s each fiber constituting sliver F guided。Thus, reverse and each fiber of rotating is wound in the fiber of central part successively。So, air spinning device 6 can utilize the swirling eddy twisting sliver F of air, thus manufacturing spinning yarn Y。
Yarn defect detecting device 7 detects the flaw portion produced in spinning yarn Y。As shown in Figure 4, yarn defect detecting device 7 is mainly made up of light source portion 71, light accepting part 72, housing 73。Arrow shown in figure represents the direction of the light irradiated from light source portion 71。
Light source portion 71 is by positively applying voltage and the semiconductor element of luminescence, i.e. light emitting diode。Light source portion 71 is configured to be irradiated on spinning yarn Y the light from this light source portion 71。
Light accepting part 72 is able to utilize optical signal to control the semiconductor element of electric current, i.e. optical transistor。Light accepting part 72 is configured to receive the light irradiated by light source portion 71。
Housing 73 is the parts that light source portion 71 and light accepting part 72 are maintained at assigned position。Housing 73 is provided with mean for the spinning yarn Y yarn path 73a passed through。Housing 73 by light source portion 71 and light accepting part 72 to keep in the way of spinning yarn Y is relative。
By such structure, the light quantity that light accepting part 72 receives is to be spun the light quantity that yarns Y covers and the value obtained from by light source portion 71 to removing the spinning yarn Y light irradiated。So, yarn defect detecting device 7 can measure the light income correspondingly changed with thickness of yarn degree such that it is able to detects the flaw portion produced in spinning yarn Y。
The flaw portion that yarn defect detecting device 7 is capable of detecting when, except the part including spinning yarn Y crosses thick or meticulous exception, is additionally included in the situation being mingled with the foreign bodies such as polypropylene in spinning yarn Y。Additionally, yarn defect detecting device 7 is except adopting optical sensor as described above, it is also possible to adopt static capacity type sensor。
Tension stabilizing device 8 moderately remains applied to the tension force on spinning yarn Y and so as to stable。It is made up of as it is shown in figure 5, tension stabilizing device 8 is main roller 81, power part 82, unwinding parts 83。Arrow shown in figure represents the direction of feed of spinning yarn Y。
Roller 81 is the rotary body of substantially cylindrical shape spinning yarn Y being drawn and being wound this spinning yarn Y from air spinning device 6。Roller 81 is arranged on the rotating shaft 82a of power part 82, rotates thereby through this power part 82。The outer peripheral face of this roller 81 it is wound onto from the spinning yarn Y of air spinning device 6 extraction。
Power part 82 is the electro-motor driven by being supplied to electric power。Power part 82 makes roller 81 rotate and with the value of regulation, the rotary speed of roller 81 is maintained constant。Thereby, it is possible to the winding speed of the spinning yarn Y being wound on roller 81 is kept constant。
Unwinding parts 83 are the yarn hooking parts unwinding of the spinning yarn Y wound assisted by rotating integratedly or independently with roller 81。The one end of unwinding parts 83 is arranged on the rotating shaft 84 of roller 81。The other end of unwinding parts 83 is formed as bending towards the outer peripheral face of roller 81。Unwinding parts 83 can by being hooked on the position of bending by spinning yarn Y and being unwind from roller 81 by this spinning yarn Y。Base portion at the rotating shaft 84 being provided with unwinding parts 83 is configured with the permanent magnet producing resistance in the way of stoping the rotation of unwinding parts 83。
By such structure, unwinding parts 83 when the tension force put on spinning yarn Y low and when being weaker than above-mentioned resistance, rotate integratedly with roller 81。On the other hand, unwinding parts 83 when the tension force put on spinning yarn Y big and more than above-mentioned resistance, rotate independently from roller 81。So, tension stabilizing device 8 can make unwinding parts 83 and roller 81 rotate integratedly or independently according to the tension force being applied on spinning yarn Y, it is possible to regulates the withdrawal speed of this spinning yarn Y。So, tension stabilizing device 8 moderately remains applied to the tension force on spinning yarn Y and so as to stable。
Tension stabilizing device 8 is when the spinning yarn Y cut off is docked by not shown yarn splicing device, it is also possible to is wound on by spinning yarn Y and accumulates on the outer peripheral face of roller 81。Therefore, tension stabilizing device 8 can absorb the lax of spinning yarn Y。
Coiler device 9 makes the package P of substantially cylindrical shape (cheese (cheese) shape) by winding spinning yarn Y。Coiler device 9 is main by driving roller 91, being constituted by the not shown reel cage that can keep in the way of rotating by spool 92。
Driving roller 91 is the rotary body making spool 92 and package P driven rotation by rotating。Drive roller 91 to change according to the external diameter of package P and regulate rotary speed, the circular velocity of this package P is remained constant。Thereby, it is possible to the winding speed of the spinning yarn Y being wound on spool 92 is kept constant。
Spool 92 is the rotary body of the substantially cylindrical shape winding spinning yarn Y by rotating。Driving roller 91 that spool 92 is rotated by the state that contacts with the outer peripheral face with this spool 92 or package P and driven rotation。Additionally, coiler device 9 makes spinning yarn Y traversing by not shown traversing gear, therefore prevent the deflection of spinning yarn Y on package P。
By such structure, it is directed to the spinning yarn Y of spool 92 without on the outer peripheral face being wound on this spool 92 on the bias。So, coiler device 9 can make the package P of substantially cylindrical shape (cheese (cheese) shape)。Additionally, coiler device 9 is except making the package P of substantially cylindrical shape (cheese (cheese) shape) as shown in Figure 1, additionally it is possible to make the package P of such as roughly conical shape (cone-shaped)。
Below, the problem points about the existing air spinning device 6 being located in spinning unit 1 is briefly described bright。
As described above, air spinning device 6 utilizes the swirling eddy of air that sliver F is twisted, thus manufacturing spinning yarn Y。In the space S C1 constituting spinning room SC, the rearward end constituting each fiber of sliver F reverses (double dot dash line with reference in Fig. 3) by swirling eddy。In the space S C2 constituting spinning room SC, the rearward end constituting each fiber of sliver F rotates (double dot dash line with reference in Fig. 3) by swirling eddy。
It is assumed for example herein that be the polyester fiber that fibre length is long and fiber stiffness is harder。When the volume of the fibre length spinning room SC for polyester fiber is little, the rearward end of polyester fiber is not easy reversion, and therefore result is to produce to twist with the fingers the spinning yarn Y that strength is weak。Illustrate, little at the volume of spinning room SC, when namely the height h of space S C1 is lower than setting, it is difficult to make the rearward end of polyester fiber reverse to be driven by swirling eddy。The polyester fiber rotated in space S C2 tails off, and polyester fiber is imported into fiber by path 62s when rotating insufficient。In situation as described above, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。
On the other hand, in the capacious situation for the fibre length spinning room SC of polyester fiber, the rearward end of polyester fiber is fully reversed, and therefore result is to produce to twist with the fingers the spinning yarn Y that strength is strong。Illustrating, big at the volume of spinning room SC, when namely the height h of space S C1 is higher than setting, the rearward end of polyester fiber is easily driven by swirling eddy, thus easily making this rearward end reverse。Therefore, the rearward end of the polyester fiber rotated in space S C2 is imported into fiber by path 62s when being fully wound on the fiber of central part。In this case, spinning yarn (heavy twist yarn) Y that sth. made by twisting strength is strong is produced。
When the height h of space S C1 is too high compared with the value of regulation, the two ends of polyester fiber are in fibre guide part 61 and spindle 62 in all free situation, fiber rotates in spinning room SC, so the frequency that fiber is discharged to the outside of air spinning device 6 increases。Thus, produce fiber loss and increase this unfavorable condition。Even if such fiber does not have fiber loss, the state on the fiber being loosely wound around central part also can be become。Therefore, the spinning yarn Y that sth. made by twisting strength is weak is produced。Further, owing to the volume of spinning room SC increases, so, the air capacity for forming swirling eddy in this spinning room SC also increases, it is necessary to carry out the maximization of air force feed device。Thus, also produce spinning unit 1 to maximize this problem。
Then, it is assumed for example that be the cotton fiber that fibre length is shorter and fiber stiffness is soft。When the volume of the fibre length spinning room SC for cotton fiber is little, the rearward end of cotton fiber is difficult to reverse, and therefore result is to produce to twist with the fingers the spinning yarn Y that strength is weak。Specifically illustrate, little at the volume of spinning room SC, when namely the height h of space S C1 is lower than setting, it is difficult to make the rearward end of cotton fiber reverse to be driven by swirling eddy。The cotton fiber rotated in space S C2 tails off, and cotton fiber is imported into fiber by path 62s when rotating insufficient。In situation as described above, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。
On the other hand, in the capacious situation for the fibre length spinning room SC of cotton fiber, the rearward end of cotton fiber is fully reversed, and therefore result is to produce to twist with the fingers the spinning yarn Y that strength is strong。Specifically illustrating, big at the volume of spinning room SC, when namely the height h of space S C1 is higher than setting, the rearward end of cotton fiber is easily driven by swirling eddy, so easily making this rearward end reverse。Therefore, the rearward end of the cotton fiber rotated in space S C2 is imported into fiber by path 62s when being fully wound on the fiber of central part。In this case, spinning yarn (heavy twist yarn) Y that sth. made by twisting strength is strong is produced。
When the height h of space S C1 is too high compared with setting, the two ends of cotton fiber are in fibre guide part 61 and spindle 62 in all free situation, cotton fiber rotates in spinning room SC, so the frequency that cotton fiber is discharged to the outside of air spinning device 6 increases。Thus, produce fiber loss and increase this unfavorable condition。Even if such fiber does not have fiber loss, the state on the fiber being loosely wound around central part also can be become。Therefore, the spinning yarn Y that sth. made by twisting strength is weak is produced。Further, owing to the volume of spinning room SC increases, also increase for the air capacity forming swirling eddy in this spinning room SC, it is necessary to carry out the maximization of air force feed device。Thus, also produce spinning unit 1 to maximize this problem。
So, air spinning device 6 owing to utilizing the swirling eddy of air to make fiber rotate, so exist be easily subject to fiber properties affect this problem。It is to say, air spinning device 6 has sth. made by twisting strength power this problem different of the difference according to the fiber properties such as fibre length, fiber stiffness and manufactured spinning yarn Y。
Therefore, in existing air spinning device 6, the replacing carrying out fibre guide part 61 and nozzle body 63 according to fiber properties is indispensable, therefore, can produce substantial amounts of the number of working processes when being manufactured spinning yarn Y by the sliver F that fiber properties is different。
Below, the air spinning device 6A of first embodiment of the present invention overcoming the problems referred to above point is illustrated。
Air spinning device 6A manufactures spinning yarn Y by drafted sliver F is twisted。As shown in Figure 6, air spinning device 6A is mainly made up of fibre guide part 61, spindle 62, nozzle body 63。Blacking arrow shown in figure represents the direction of feed of sliver F and spinning yarn Y。Hollow arrow shown in figure represents the flow direction of the air supplied。
As shown in Figure 6, the air spinning device 6A of present embodiment is and existing air spinning device 6 same structure (with reference to Fig. 3)。But, this some difference as follows: be provided with the protuberance 61b in the through hole 63p being embedded into nozzle body 63 on the fibre guide part 61 of air spinning device 6A。
Air spinning device 6A, the same with existing air spinning device 6, utilize the swirling eddy of air that sliver F twisting is manufactured spinning yarn Y。In the space S C1 constituting spinning room SC, the rearward end constituting each fiber of sliver F reverses (double dot dash line with reference in Fig. 6) by swirling eddy。In the space S C2 constituting spinning room SC, the rearward end constituting each fiber of sliver F rotates (with reference to double dot dash line in Fig. 6) by swirling eddy。
It is assumed for example herein that be the polyester fiber that fibre length is long and fiber stiffness is harder。As it has been described above, when the height h of space S C1 is lower than setting, owing to the rearward end of polyester fiber was imported into fiber by path 62s before being fully rotatable, so, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6A of present embodiment by other short for the length L being replaced with the protuberance 61b being located on fibre guide part 61 fibre guide parts 61。
As mentioned above, when the height h of space S C1 is too high compared with setting, being imported into fiber due to the part of polyester fiber on the fiber being loosely wound around central part by path 62s, twisting with the fingers, so producing, spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6A of present embodiment by being replaced with other fibre guide parts 61 of the length L length of the protuberance 61b being located on fibre guide part 61。
Then, it is assumed for example that be the cotton fiber that fibre length is shorter and fiber stiffness is soft。As it has been described above, when the height h of space S C1 is lower than setting, owing to the rearward end of cotton fiber was imported into fiber by path 62s before being fully rotatable, so, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6A of present embodiment by other short for the length L being replaced with the protuberance 61b being located on fibre guide part 61 fibre guide parts 61。
As mentioned above, when the height h of space S C1 is too high compared with setting, being imported into fiber due to the part of cotton fiber on the fiber being loosely wound around central part by path 62s, twisting with the fingers, so producing, spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6A of present embodiment by being replaced with other fibre guide parts 61 of the length L length of the protuberance 61b being located on fibre guide part 61。
By such structure, the air spinning device 6A of present embodiment only just can change the height h of space S C1 in a straightforward manner by changing fibre guide part 61。That is, spinning room SC only just can be adjusted to the volume adapted with fiber properties by replacing fibre guide part 61 by air spinning device 6A in a straightforward manner。Thus, air spinning device 6A can easily spin according to fiber properties。
Even additionally, as it is shown in fig. 7, to be not provided with the structure of pin 61n, the purpose of the present invention and effect on fibre guide part 61 also without the slightest difference, belonging to the technical scope of the present invention。In this case, air spinning device 6A collects sliver F in the end of downstream side of fibre guide part 61, and the fiber guiding this sliver F to spindle 62 passes through path 62s。
Then, the air spinning device 6B of second embodiment of the present invention overcoming the problems referred to above point is illustrated。
Air spinning device 6B manufactures spinning yarn Y by drafted sliver F is twisted。As shown in Figure 8, air spinning device 6B is mainly made up of fibre guide part 61, spindle 62, nozzle body 63。Blacking arrow shown in figure represents the direction of feed of sliver F and spinning yarn Y。Hollow arrow shown in figure represents the flow direction of the air supplied。
As shown in Figure 8, the air spinning device 6B of present embodiment is and existing air spinning device 6 same structure (with reference to Fig. 3)。But, this some difference as follows: be provided with the recess 61c connected of the through hole 63p with nozzle body 63 on the fibre guide part 61 of air spinning device 6B。
Air spinning device 6B, the same with existing air spinning device 6, utilize the swirling eddy of air that sliver F twisting is manufactured spinning yarn Y。In the space S C1 constituting spinning room SC, the rearward end constituting each fiber of sliver F reverses (double dot dash line with reference in Fig. 8) by swirling eddy。In the space S C2 constituting spinning room SC, the rearward end constituting each fiber of sliver F rotates (double dot dash line with reference in Fig. 8) by swirling eddy。
It is assumed for example herein that be the polyester fiber that fibre length is long and fiber stiffness is harder。As it has been described above, when the height h of space S C1 is lower than setting, owing to the rearward end of polyester fiber was imported into fiber by path 62s before being fully rotatable, so, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6B of present embodiment by other deep for the degree of depth D being replaced with the recess 61c being located on fibre guide part 61 fibre guide parts 61。
As mentioned above, when the height h of space S C1 is too high compared with the value of regulation, being imported into fiber due to the part of polyester fiber on the fiber being loosely wound around central part by path 62s, twisting with the fingers, so producing, spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6B of present embodiment by other shallow for the degree of depth D being replaced with the recess 61c being located on fibre guide part 61 fibre guide parts 61。
Then, it is assumed for example that be the cotton fiber that fibre length is shorter and fiber stiffness is soft。As it has been described above, when the height h of space S C1 is lower than setting, owing to the rearward end of cotton fiber was imported into fiber by path 62s before being fully rotatable, so, produce and twist with the fingers spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6B of present embodiment by other deep for the degree of depth D being replaced with the recess 61c being located on fibre guide part 61 fibre guide parts 61。
As mentioned above, when the height h of space S C1 is too high compared with setting, being imported into fiber due to the part of cotton fiber on the fiber being loosely wound around central part by path 62s, twisting with the fingers, so producing, spinning yarn (loose twist yarn) Y that strength is weak。But, the height h of space S C1 can be regulated to optimum by the air spinning device 6B of present embodiment by other shallow for the degree of depth D being replaced with the recess 61c being located on fibre guide part 61 fibre guide parts 61。
By such structure, the air spinning device 6B of present embodiment only just can change the height of space S C1 in a straightforward manner by changing fibre guide part 61。That is, spinning room SC only just can be adjusted to the volume adapted with fiber properties by replacing fibre guide part 61 by air spinning device 6B in a straightforward manner。Thus, air spinning device 6B can easily spin according to fiber properties。
Even additionally, as it is shown in figure 9, to be not provided with the structure of pin 61n, the purpose of the present invention and effect on fibre guide part 61 also without the slightest difference, belonging to the technical scope of the present invention。In this case, air spinning device 6B collects sliver F in the end of downstream side of fibre guide part 61, and the fiber guiding this sliver F to spindle 62 passes through path 62s。
Below, the position of the airport 63a being located on nozzle body 63 is illustrated。
Figure 10 is the enlarged drawing of spinning room SC part。Hollow arrow shown in figure represents the flow direction of the air supplied。
It is located at each airport 63a on nozzle body 63 and stays the top (upstream part) lower section (downstream part) the oblique connection towards the space S C1 constituting spinning room SC of room AC from air storage。Storage is stayed air storage and is stayed the air in the AC of room to be supplied to spinning room SC by each airport 63a。
Air spinning device 6A, 6B are characterised by, the intersection I S1 of the wall of the central shaft of airport 63a and through hole 63p is arranged in the scope that distance is more than 3mm and below 10mm from nozzle body 63 and the bearing surface X of fibre guide part 61。
By guaranteeing at more than 3mm and below 10mm to the size of bearing surface X from intersection I S1, it is possible to form airport 63a so that producing swirling eddy in spinning room SC。That is, when from intersection I S1 to the undersize 3mm of bearing surface X, airport 63a vertically or is generally perpendicularly arranged relative to spinning room SC。In this case, owing to not producing swirling eddy in spinning room SC, so fiber reversion cannot be made and rotates。When from intersection I S1 to the size of bearing surface X bigger than 10mm, the volume of spinning room SC is big, and air spinning device 6 can maximize, and required specific air consumption can increase。Owing to the volume of spinning room SC is big, so being not easy to make fibre high-speed rotate in spinning room SC, thus the sth. made by twisting strength of the spinning yarn Y produced is weak。It is important, therefore, that the intersection I S1 of the central shaft of airport 63a Yu the wall of through hole 63p is arranged in the scope that distance is more than 3mm and below 10mm from nozzle body 63 and the bearing surface X of fibre guide part 61。
By such structure, the sliver F different even with fiber properties manufactures spinning yarn Y, is also not readily susceptible to the impact of fiber properties, and the power of the sth. made by twisting strength of manufactured spinning yarn Y is stable。And, by being replaced with the fibre guide part 61 adapted with fiber properties on its basis, it is possible to easily make the performance optimal of spinning yarn Y。That is, owing to being of a size of more than 3mm and below 10mm from intersection I S1 to bearing surface X, it is possible to easily vary the length of the protuberance 61b of fibre guide part 61。Thus, air spinning device 6A, 6B can easily carry out the spinning according to fiber properties。
Air spinning device 6A, 6B are characterised by, the intersection I S2 of the outside wall surface of the central shaft of airport 63a and nozzle body 63 is arranged on the bearing surface X from this nozzle body 63 with fibre guide part 61 and leaves the position of more than 1mm。The value of more than 1mm is, with the stability of the sth. made by twisting strength of spinning yarn Y that produces for parameter, and the value determined by testing。Specifically, the value of more than 1mm it is possible to stay room AC to be supplied uniformly across air through airport 63a to spinning room SC thus producing the value of stable swirling eddy from air storage。
This is because, leave near the upper wall surface (wall of upstream-side-end) of room AC by making the inlet portion of airport 63a stay from air storage, the flowing of the air flowing into each airport 63a will not be hindered。When each airport 63a being arranged on the position leaving more than 1mm from the bearing surface X of nozzle body 63 with fibre guide part 61, owing to the height of neck H of nozzle body 63 necessarily uprises, so, air storage stays the volume of room AC to increase, so that the flowing that must flow into the air of each airport 63a is good。
By such structure, owing to air can be supplied uniformly across through multiple airport 63a to spinning room SC, so the power of the sth. made by twisting strength of manufactured spinning yarn Y is stable。And, by being replaced with the fibre guide part 61 adapted with fiber properties on its basis, it is possible to easily make the performance optimal of spinning yarn Y。Thus, air spinning device 6A, 6B can easily carry out the spinning according to fiber properties。
Further, positioning away from from the bearing surface X of nozzle body 63 with fibre guide part 61 owing to airport 63a is formed, so, the foreign body being attached on bearing surface X is difficult to enter airport 63a。Such as, the fag-end etc. being arranged on the o-ring 61o of the peripheral part of fibre guide part 61 is difficult to enter airport 63a。Thereby, it is possible to prevent from being mixed into foreign body in manufactured spinning yarn Y。
When foreign body from air storage stay room AC enter be mixed into spinning yarn Y in spinning room SC, spinning unit 1 is necessary to remove this partly as the yarn defect portion of spinning yarn Y。In this case, owing to spinning unit 1 needs carry out the cut-out of spinning yarn Y and connect yarn operation, so, coiler device 9 the winding job interruption of the spinning yarn Y carried out, the production efficiency of the spinning yarn Y of spinning unit 1 is low。But, by this air spinning device 6, it is mixed in spinning yarn Y owing to being prevented from foreign body, so, the production efficiency of the spinning yarn Y of spinning unit 1 will not be low。
There is the spinning that the spinning unit 1 of above such air spinning device 6A, 6B can easily carry out adapting with fiber properties。Thus, improve the production efficiency of spinning yarn Y。
Additionally, above-mentioned spinning unit 1 is the structure utilizing tension stabilizing device 8 to be drawn by the spinning yarn Y spun in air spinning device 6A, 6B and accumulate temporarily。But, spinning unit 1 is not limited to such structure。For example, it is also possible to be, at the downstream of air spinning device 6A, 6B configuration conveying roller and gripping roller, draw spinning yarn Y by this conveying roller and gripping roller from air spinning device 6A, 6B。Further, can also be, at the downstream configuration tension stabilizing device 8 of conveying roller and gripping roller, carry the spinning yarn Y that roller and gripping roller are drawn from air spinning device 6A, 6B to be accumulated in tension stabilizing device 8 by passing through temporarily。Or, it is also possible to it is configured to omit tension stabilizing device 8 and directly wind spinning yarn Y by coiler device 9。
