Housing is the parts that light source portion and light accepting part remained on the position of regulation.Be provided with the yarn path that supplies spun yarn Y to pass through at housing.Housing is so that light source portion and light accepting part keep light source portion and light accepting part across the opposed mode of spun yarn Y.
By this structure, the light quantity that light accepting part received is removing by the value after the light quantity of spun yarn Y shading the light that shines from light source portion towards spun yarn Y.Like this, yarn defect checkout gear 7 can be measured the light income that correspondingly changes with thickness of yarn, can detect the fault portion that produces at spun yarn Y.
In addition, the fault portion that 7 of yarn defect checkout gears can detect except a part that comprises spun yarn Y cross thick or meticulous unusual, also be included in the situation that spun yarn Y accompanies foreign matters such as polypropylene.And yarn defect checkout gear 7 can also adopt the sensor of electrostatic capacitive except the sensor that can adopt aforesaid optical profile type.
The tension force that tension stabilizing device 8 will put on spun yarn Y remains on the tension force of appropriateness and makes it stable.As shown in Figure 4, tension stabilizing device 8 mainly by roller 81, power part 82, separate the parts 83 that relax and constitute.In addition, the arrow shown in the figure is represented the throughput direction of spun yarn Y.
Separate the parts 83 that relax and be through rotate integratedly with roller 81 or independent rotation and the yarn guide member that Shu Jinhang assists of separating of the spun yarn Y that reeled.One end of separating the parts 83 that relax is installed on the rotating shaft 84 of roller 81.The other end of separating the parts 83 that relax forms towards the outer peripheral face of roller 81 crooked.Separate the parts 83 that relax and collude extension spun yarn Y at the position of bending, can separate easypro from roller 81 this spun yarn Y thus.In addition, dispose the permanent magnet (not shown) that produces resistance with the mode that overcomes the rotation of separating the parts 83 that relax at the base portion that the rotating shaft 84 of separating the parts 83 that relax is installed.
By this structure, low and be defeated by under the situation of above-mentioned resistance at the tension force that puts on spun yarn Y, separate the parts 83 that relax rotate with becoming one with roller 81.On the other hand, surpass under the situation of above-mentioned resistance, separate the parts 83 that relax and rotate independently with roller 81 at the tension force height that puts on spun yarn Y.Tension stabilizing device 8 can make to separate and relax parts 83 and roller 81 integratedly or rotation independently according to the tension force that puts on spun yarn Y, can the Shu Sudu that separates of this spun yarn Y be regulated.Like this, tension stabilizing device 8 can remain on the tension force that puts on spun yarn Y the pressure of appropriateness and make it stable.
In addition, as stated, tension stabilizing device 8 has the function that spun yarn Y is drawn from open end spinning apparatus 6.But, for example also can utilize this delivery roller and niproll that spun yarn Y is drawn at the downstream of open end spinning apparatus 6 configuration delivery roller and niproll.In addition, also can form configuration tension stabilizing device 8 and the structure of coiling spun yarn Y to store in the downstream of delivery roller and niproll.Perhaps, also can omit tension stabilizing device 8, and form the structure of utilizing batching apparatus 9 that spun yarn Y is drawn.
Batching apparatus 9 is made the package P of general cylindrical shape shape (bobbin shape) through coiling spun yarn Y.Batching apparatus 9 mainly constitutes with not shown reel cage by driving roller 91.Reel cage remains rotation freely with bobbin 92.
Drive roller 91 and rotary speed is regulated, make the circumferential speed of this package P keep constant according to the variation of the external diameter of package P.Thus, can the winding speed of the spun yarn Y that be wound in bobbin 92 be kept constant.
Bobbin 92 is rotary bodies of the general cylindrical shape shape of coiling spun yarn Y through rotation.Bobbin 92 by with the outer peripheral face state of contact of this bobbin 92 or package P under the driving roller 91 that rotates drive and driven rotation.In addition, batching apparatus 9 also utilizes not shown traversing gear that spun yarn Y is traversed, and therefore can prevent the biasing of the spun yarn Y among the package P.
By this structure, the spun yarn Y that is directed to bobbin 92 is wound in the outer peripheral face of this bobbin 92 with the mode that can not be partial to.Like this, batching apparatus 9 can be made the package P of general cylindrical shape shape (bobbin shape).In addition, batching apparatus 9 also can be made the for example package P of conical shaped shape (cone-shaped) except the package P that can make general cylindrical shape shape as shown in Figure 1 (bobbin shape).
Secondly, use Figure 12 that the thread-carrier 161 of in the past open end spinning apparatus 106 and the fixing means of nozzle block 163 are described.Figure 12 illustrates the side view of open end spinning apparatus 106 in the past.
Nozzle block 163 is supported by nozzle carrier 164 with the state of the through hole 165h of the through hole 164h that embeds nozzle carrier 164 and liner 165.Explanation particularly, nozzle block 163 is embedded in the through hole 164h of nozzle carrier 164 and the through hole 165h of liner 165, is supported by nozzle carrier 164 with the stop surface 163p of this nozzle block 163 and the state of liner 165 butts.
Thread-carrier 161 is combined in the upper end (fibre bundle direct of travel upstream side end face) of nozzle block 163.Explanation particularly, thread-carrier 161 are combined in the upper end of nozzle block 163 with the bottom (fibre bundle direct of travel downstream end face) of this thread-carrier 161 the state of recess is supported.
Thread-carrier 161 is fixed in nozzle carrier 164 by cap of spraying nozzle 166 via liner 165 with nozzle block 163 under the state of combination each other.Explanation particularly, thread-carrier 161 and nozzle block 163 utilize claw to collude to be hung on the cap of spraying nozzle 166 of thread-carrier 161 and are fixed in nozzle carrier 164 with liner 165.
Like this, in open end spinning apparatus 106 in the past, thread-carrier 161 and nozzle block 163 are fixed on the liner 165, then this liner 165 are fixed in nozzle carrier 164.This is because in spinning unit 1, form open end spinning apparatus 106 and the structures of front roller to 54 approaching settings, so the operator is difficult to directly be used for thread-carrier 161 and nozzle block 163 are installed on the operation of nozzle carrier 164.And; Put down the 4-131661 communique as real the opening of Japan; Generally two open end spinning apparatus 106 with respect to adjacency are provided with common nozzle carrier, under the situation that thread-carrier 161 and nozzle block 163 is installed on open end spinning apparatus 106, have to use liner 165.
Here, the problem that the fixing means because of this thread-carrier 161 and nozzle block 163 is produced describes.
Between the stop surface 163p of nozzle block 163 and nozzle carrier 164, be provided with in the structure of open end spinning apparatus in the past 106 of liner 165, can be through changing the installation site that this liner 165 changes thread-carrier 161 and nozzle block 163.But, when also accumulation when the tolerance of liner 165 is arranged except the tolerance of thread-carrier 161, nozzle block 163, cap of spraying nozzle 166, the situation that exists the precision of the installation site of thread-carrier 161, nozzle block 163 to reduce.
Under the situation littler than setting of the interval D between thread-carrier 161 and the hollow guiding axis body 162, the rearward end that constitutes the fiber of sliver F is difficult to counter-rotating, and the result can produce the weak spun yarn Y of the twist.Explanation particularly, under the situation that the interval D between thread-carrier 161 and the hollow guiding axis body 162 diminishes, the rearward end that constitutes the fiber of sliver F is difficult to taking advantage of gyration airflow, therefore is difficult to make the rearward end counter-rotating of fiber.Thereby, the fiber that constitutes sliver F is circled round and make it be wound in the fiber of central part fully.As a result, can produce weak spun yarn (soft twist yarn) Y of the twist.
Interval D between thread-carrier 161 and hollow guiding axis body 162 is under the situation of setting, and the rearward end that constitutes the fiber of sliver F is reversed easily, and the result can produce the strong spun yarn Y of the twist.Explanation particularly, the interval D between thread-carrier 161 and hollow guiding axis body 162 is under the situation of setting, the rearward end that constitutes the fiber of sliver F is being taken advantage of gyration airflow easily, therefore makes the rearward end counter-rotating of fiber easily.Thereby, can make the fiber of taking advantage of gyration airflow to circle round be wound in the fiber of central part fully.As a result, can produce the strong spun yarn of the twist (tight twist yarn) Y.
Under the excessive situation of the interval D between thread-carrier 161 and the hollow guiding axis body 162, the two ends of the fiber of formation sliver F are both increased by the frequency that thread-carrier 161 constraints were not circled round in spinning room SC by 162 constraints of hollow guiding axis body yet and quilt is discharged towards the outside of air-flow spinning apparatus 106.Thus, can produce the unfavorable condition that fiber loss (fiber loss) increases.And because the volume of spinning room SC increases, the air capacity that therefore is used for formation gyration airflow in spinning room SC also increases, and the air supply source is maximized.Thus, can produce the problem that spinning unit maximizes.
Like this, because open end spinning apparatus 106 utilizes the gyration airflow of air that fiber is circled round, therefore receive the influence of spinning room SC shape easily.For open end spinning apparatus 106, when because of the change in shape of the skew spinning room SC of the installation site of the thread-carrier 161 that constitutes spinning room SC, nozzle block 163 etc., there is the strong and weak condition of different of the twist of the spun yarn Y of manufacturing.And, the situation that exists fiber loss to increase.Thereby, thereby the precision of seeking to improve the installation site of thread-carrier 161, nozzle block 163 can reduce the open end spinning apparatus 106 of the deviation of spinning room SC shape.
Secondly, use Fig. 5 that the thread-carrier 61 of the related open end spinning apparatus 6 of the embodiment of the utility model and the fixing means of nozzle block 63 are described.Fig. 5 illustrates the side view of the related open end spinning apparatus 6 of the embodiment of the utility model.
Thread-carrier 61 is combined in the upper end (fibre bundle direct of travel upstream side end face) of nozzle block 63.Explanation particularly, thread-carrier 61 are combined in the upper end of nozzle block 63 with the bottom (fibre bundle direct of travel downstream end face) of this thread-carrier 61 the state of recess is supported.
Thread-carrier 61 is fixed in nozzle carrier 64 by cap of spraying nozzle 66 with nozzle block 63 under the state of combination each other.Explanation particularly, thread-carrier 61 colludes the cap of spraying nozzle 66 that is hung on thread-carrier 61 with nozzle block 63 by claw and is directly fixed on nozzle carrier 64.
