In addition, as shown in Figure 3, open end spinning apparatus 6 also can be configured to not arrange pin 61n at thread-carrier 61.In this case, thread-carrier 61 utilizes the edge of the downstream of this thread-carrier 61 to realize the function of pin 61n.Even if do not arrange the structure of pin 61n at thread-carrier 61, object of the present invention and effect also not there are differences, and are also under the jurisdiction of technical scope of the present invention.
Yarn defect checkout gear 7 detects the fault portion produced at spun yarn Y.Yarn defect checkout gear 7 is formed primarily of light source portion (not shown), light accepting part (not shown) and housing (not shown).
Light source portion is by the semiconductor element of luminescence, i.e. light emitting diode along clockwise direction applying voltage.Light source portion is configured to the illumination from this light source portion to be incident upon spun yarn Y.
Light accepting part is semiconductor element, the i.e. photistor that optical signal can be utilized to control electric current.Light accepting part is configured to receive the light irradiated by light source portion.
Housing is the parts of position light source portion and light accepting part being remained on regulation.The yarn path passed through for spun yarn Y is provided with at housing.Housing keeps light source portion and light accepting part to make light source portion and light accepting part across the mode that spun yarn Y is opposed.
By this structure, the light quantity that light accepting part receives is that the removing the light irradiated from light source portion towards spun yarn Y is by the value after the light quantity of spun yarn Y shading.Like this, yarn defect checkout gear 7 can measure the light income correspondingly changed with thickness of yarn, can detect the fault portion produced at spun yarn Y.
In addition, the fault portion that yarn defect checkout gear 7 can detect, except the part comprising spun yarn Y crosses thick or meticulous exception, is also included in the situation that spun yarn Y accompanies the foreign matters such as polypropylene.Further, yarn defect checkout gear 7, except can adopting the sensor of optical profile type as above, can also adopt the sensor of electrostatic capacitive.
The tension force putting on spun yarn Y is remained on the tension force of appropriateness and makes it stablize by tension stabilizing device 8.As shown in Figure 4, tension stabilizing device 8 is formed primarily of roller 81, power part 82, unwinding parts 83.In addition, the arrow shown in figure represents the throughput direction of spun yarn Y.
Roller 81 is drawn and the rotary body of the substantially cylindrical shape of this spun yarn Y that reels from open end spinning apparatus 6 by spun yarn Y.Roller 81 is installed on the rotating shaft 82a of power part 82 and drives rotation by this power part 82.The outer peripheral face of this roller 81 is wound in by the spun yarn Y drawn from open end spinning apparatus 6.
Power part 82 is the motor being undertaken by supply electric power driving.Power part 82 makes roller 81 rotate, and the rotary speed of this roller 81 is remained constant at setting.Thereby, it is possible to make the winding speed of the spun yarn Y being wound in roller 81 keep constant.
Unwinding parts 83 are the unwinding yarn guide members of assisting by rotating integratedly with roller 81 or independently rotating to reeled spun yarn Y.One end of unwinding parts 83 is installed 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, thus can by unwinding from roller 81 for this spun yarn Y at bending position hooking spun yarn Y.In addition, the mode being configured with the rotation overcoming unwinding parts 83 at the base portion of the rotating shaft 84 being provided with unwinding parts 83 produces the permanent magnet (not shown) of resistance.
By this structure, when the tension force putting on spun yarn Y low and be defeated by above-mentioned resistance, unwinding parts 83 and roller 81 become and rotate integratedly.On the other hand, when the tension force putting on spun yarn Y high and surpass above-mentioned resistance, unwinding parts 83 and roller 81 rotate independently.Tension stabilizing device 8 can make unwinding parts 83 rotate integratedly or independently with roller 81 according to the tension force putting on spun yarn Y, can regulate the unwinding speed of this spun yarn Y.Like this, the tension force putting on spun yarn Y can be remained on the pressure of appropriateness and make it stablize by tension stabilizing device 8.
In addition, as mentioned above, tension stabilizing device 8 has the function of being drawn from open end spinning apparatus 6 by spun yarn Y.But, such as, also can, at the downstream of open end spinning apparatus 6 configuration delivery roller and niproll, utilize this delivery roller and niproll to be drawn by spun yarn Y.In addition, the spun yarn Y that reels can be also formed as at the downstream of delivery roller and niproll configuration tension stabilizing device 8 to carry out the structure of storing.Or, also can omit tension stabilizing device 8, and be formed as the structure that utilizes batching apparatus 9 to be drawn by spun yarn Y.
Batching apparatus 9 makes the package P of substantially cylindrical shape (bobbin shape) by winding spun yarn Y.Batching apparatus 9 is formed primarily of driving roller 91 and not shown reel cage.Bobbin 92 remains rotatable by reel cage.
Drive roller 91 to regulate rotary speed according to the change of the external diameter of package P, make the circumferential speed of this package P remain constant.Thereby, it is possible to the winding speed being wound in the spun yarn Y of bobbin 92 is kept constant.
Bobbin 92 is the rotary bodies of substantially cylindrical shape of spun yarn Y of reeling by rotating.Bobbin 92 is driven and driven rotation by the driving roller 91 rotated under the state contacted with the outer peripheral face of this bobbin 92 or package P.In addition, batching apparatus 9 also utilizes not shown traversing gear to make spun yarn Y traversing, therefore, it is possible to prevent being biased of the spun yarn Y in package P.
By this structure, the spun yarn Y being directed to bobbin 92 is wound in the outer peripheral face of this bobbin 92 in the mode that can not be partial to.Like this, batching apparatus 9 can make the package P of substantially cylindrical shape (bobbin shape).In addition, batching apparatus 9 except can making the package P of substantially cylindrical shape (bobbin shape) as shown in Figure 1, also can production example as the package P of roughly conical shape (cone-shaped).
Secondly, Figure 12 is used to be described the thread-carrier 161 of open end spinning apparatus 106 in the past and the fixing means of nozzle block 163.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 and liner 165 that embed nozzle carrier 164.Specifically describe, nozzle block 163 is embedded in the through hole 164h of the nozzle carrier 164 and through hole 165h of liner 165, is supported by nozzle carrier 164 with the state that the stop surface 163p of this nozzle block 163 abuts with liner 165.
Thread-carrier 161 is combined in the upper end (fibre bundle direct of travel upstream-side end surface) of nozzle block 163.Specifically describe, the state that thread-carrier 161 is combined in the recess of the upper end of nozzle block 163 with the bottom of this thread-carrier 161 (fibre bundle direct of travel downstream-side end surface) is supported.
Thread-carrier 161 and nozzle block 163 are fixed on nozzle carrier 164 by cap of spraying nozzle 166 via liner 165 under the state of combination mutually.Specifically describe, thread-carrier 161 and nozzle block 163 utilize claw hooking to be fixed on nozzle carrier 164 in the cap of spraying nozzle 166 of thread-carrier 161 together with liner 165.
Like this, in open end spinning apparatus 106 in the past, thread-carrier 161 and nozzle block 163 are fixed on liner 165, then this liner 165 are fixed on nozzle carrier 164.This is because in spinning unit 1, be formed as open end spinning apparatus 106 and front roller to 54 close to the structures arranged, therefore operator is difficult to the operation directly carried out for thread-carrier 161 and nozzle block 163 being installed on nozzle carrier 164.And, as Japanese Patent Publication 4-131661 publication, generally common nozzle carrier is set relative to two adjacent open end spinning apparatus 106, has to when thread-carrier 161 and nozzle block 163 are installed on open end spinning apparatus 106 use liner 165.
Herein, the problem produced the fixing means because of this thread-carrier 161 and nozzle block 163 is described.
Being provided with between the stop surface 163p and nozzle carrier 164 of nozzle block 163 in the structure of open end spinning apparatus 106 in the past of liner 165, the installation site of thread-carrier 161 and nozzle block 163 can be changed by changing this liner 165.But, when also accumulation has a tolerance of liner 165 except the tolerance except thread-carrier 161, nozzle block 163, cap of spraying nozzle 166, there is thread-carrier 161, situation that the precision of installation site of nozzle block 163 reduces.
When interval D between thread-carrier 161 and hollow guide shaft body 162 is less than setting, the rearward end forming the fiber of sliver F is difficult to reversion, and result can produce the weak spun yarn Y of the twist.Specifically describe, when the interval D between thread-carrier 161 and hollow guide shaft body 162 diminishes, the rearward end forming the fiber of sliver F is difficult to take advantage of gyration airflow, is therefore difficult to make the rearward end of fiber to be reversed.Thus, the fiber of formation sliver F cannot be made to circle round and make it be wound in the fiber of central part fully.As a result, the weak spun yarn of the twist (soft twist yarn) Y can be produced.
When interval D between thread-carrier 161 and hollow guide shaft body 162 is setting, the rearward end forming the fiber of sliver F is easily reversed, and result can produce the strong spun yarn Y of the twist.Specifically describe, the interval D between thread-carrier 161 and hollow guide shaft body 162 is setting, the rearward end forming the fiber of sliver F easily takes advantage of gyration airflow, therefore easily makes the rearward end of fiber reverse.Thus, can make to take advantage of the fiber of gyration airflow convolution to be wound in the fiber of central part fully.As a result, the strong spun yarn of the twist (tight twist yarn) Y can be produced.
When interval D between thread-carrier 161 and hollow guide shaft body 162 is excessive, the two ends forming the fiber of sliver F had not both been retrained by thread-carrier 161 and had not been retrained by hollow guide shaft body 162 and convolution being increased by the frequency that the outside towards open end spinning apparatus 106 is discharged in spinning room SC yet.Thus, the unfavorable condition that fiber loss (fiberloss) increases can be produced.Further, because the volume of spinning room SC increases, the air capacity therefore for forming gyration airflow in spinning room SC also increases, and needs air supply source is maximized.Thus, the problem that spinning unit maximizes can be produced.
Like this, because open end spinning apparatus 106 utilizes the gyration airflow of air to make fiber circle round, the impact of spinning room SC shape is therefore easily subject to.For open end spinning apparatus 106, when the skew of the installation site of the thread-carrier 161, nozzle block 163 etc. because forming spinning room SC during the change in shape of spinning room SC, the situation that the power of the twist of the spun yarn Y manufactured by existence is different.Further, there is the situation that fiber loss increases.Thus, seek to improve thread-carrier 161, nozzle block 163 installation site precision thus the open end spinning apparatus 106 of the deviation of spinning room SC shape can be reduced.
Secondly, Fig. 5 is used to be described the thread-carrier 61 of the open end spinning apparatus 6 involved by embodiments of the present invention and the fixing means of nozzle block 63.Fig. 5 illustrates the side view of the open end spinning apparatus 6 involved by embodiments of the present invention.
Nozzle block 63 is supported with the state of the through hole 64h being embedded in nozzle carrier 64.Specifically describe, nozzle block 63 is embedded in the through hole 64h of nozzle carrier 64, is supported with the state that the stop surface 63p of this nozzle block 63 abuts with nozzle carrier 64.
Thread-carrier 61 is combined in the upper end (fibre bundle direct of travel upstream-side end surface) of nozzle block 63.Specifically describe, the state that thread-carrier 61 is combined in the recess of the upper end of nozzle block 63 with the bottom of this thread-carrier 61 (fibre bundle direct of travel downstream-side end surface) is supported.
Thread-carrier 61 and nozzle block 63 are fixed on nozzle carrier 64 by cap of spraying nozzle 66 under the state of combination mutually.Specifically describe, thread-carrier 61 and nozzle block 63 are directly fixed on nozzle carrier 64 by claw hooking in the cap of spraying nozzle 66 of thread-carrier 61.
By this structure, owing to utilizing with the cap of spraying nozzle 66 installed with the state that nozzle carrier 64 directly abuts, with the state fixed nozzle block 63 of the stop surface 63p of nozzle block 63 and nozzle block 64 abutting, the therefore precision raising of the installation site of this nozzle block 63.The precision of the installation site of the thread-carrier 61 be fixed with the state combined with nozzle block 63 also improves.Thus, the deviation of spinning room SC shape reduces, and can improve the quality of spun yarn Y.Further, due to simple structure fixed thread guide 61 and nozzle block 63 can be utilized, reduce therefore, it is possible to realize cost.
As Japanese Patent Publication 4-131661 publication, arrange in the structure of a location-plate relative to two adjacent open end spinning apparatus 106, the restriction produced by location-plate can be subject to.Thus, be difficult to freely carry out the location of open end spinning apparatus 106 relative to drafting system for each spinning unit.But, as in the present embodiment, by thread-carrier 61 and nozzle block 63 are fixed on nozzle carrier 64, can freely carry out the location of open end spinning apparatus 6 relative to drafting system 5 for each spinning unit 1.
As mentioned above, open end spinning apparatus 6 utilizes the gyration airflow of air that fiber is circled round, and is therefore easily subject to the impact of fiber properties.For open end spinning apparatus 6, due to fiber properties such as average fiber length, the situation that the power of the twist of the spun yarn Y manufactured by existence is different.Thus, thread-carrier 61, the nozzle block 63 thus open end spinning apparatus 6 of the spinning corresponding to fiber properties can be carried out is sought easily to change.
Secondly, use Fig. 5 to thread-carrier 61 easily can be changed, the structure of nozzle block 63 is described.
The nozzle carrier 64 forming this open end spinning apparatus 6 is made up of first jet seat portion 64A and second nozzle seat portion 64B.In addition, the arrow of the blacking shown in figure illustrates the handling direction of first jet seat portion 64A.
