Spinning section 3 is by making spinning Y with the fiber bundle F twisting of drafted mistake.Spinning section 3 is configured in the downstream of drawing-off section 2 at the direction of travel of spinning Y.Spinning section 3 can be from the Y that spinned by the fiber bundle F manufacturing of appropriate drawing-off.The structure aftermentioned of relevant spinning section 3.

Yarn defect test section 4 detects the defective part of the spinning Y that produces.Specify as, yarn defect test section 4 with light emitting diode (not shown) as light source irradiation spinning Y, detect the reflection light quantity from this spinning Y.Yarn defect test section 4 is connected on the control part 40 by analyzer (not shown).Control part 40 has or not defective part according to judging from the detection signal of yarn defect test section 4.Near yarn defect test section 4, be provided with the cutter 41 that spinning Y can be cut off.The defective part of spinning Y except the spinning part excessively thick (bead) of Y or meticulous (fine-count yarn) unusually, also comprise the foreign matter that is present among the Y that spins.Yarn defect test section 4 except optical sensor, also can adopt capacitance type sensor etc. in this example.

Tension stability section 5 will be applied to the tension force appropriateness maintenance on the spinning Y and make it stable.Tension stability section 5 has unwinding parts 51 and roller 52.With roller 52 rotations, the Y that will spin was wound up on this roller 52 when the tension force of unwinding parts 51 on being applied to spinning Y was low.Rotate independently mutually with roller 52 when the tension force of unwinding parts 51 on being applied to spinning Y is high, with the spinning Y unwinding that is wound up on this roller 52.Tension stability section 5 can will be applied to the tension force appropriateness maintenance on the spinning Y and make it stable.Roller 52 is by not shown motor rotary actuation.

Winder 6 coiling spinning Y make package P.Winder 6 has driven roller 61 and reel cage 62.Driven roller 61 makes the bobbin B rotation of being controlled by reel cage 62 by not shown motor rotary actuation with rotating freely.Thus, winder 6 can the limit makes package P with the not shown traversing gear spinning Y limit spinning Y that reels that traverses.

Mobile workbench 20 then is described.Mobile workbench 20 possesses braking parts 21, reverse roll 22, drive division 23, guide portion 24 and connector portions 25.

Braking parts 21 can contact with package P the rotation brake (with reference to Fig. 3) with this package P.In this example, braking parts 21 possesses the plate 21a that contacts with the outer peripheral face of package P and the arm 21b that supports this plate 21a.As long as it is just passable that braking parts 21 can contact the rotation brake of this package P with package P, relevant shape or structure etc. are without limits.

It is unreeling direction rotation (reverse) (with reference to Fig. 4, Fig. 5 and Fig. 6) along the direction opposite with coiling direction that reverse roll 22 makes this package P with package P contact.Detailed description is, reverse roll 22 contacts with package P after the outer peripheral face of package P leaves at the plate 21a of braking parts 21, and this package P is reversed.

Drive division 23 makes reverse roll 22 rotations (with reference to Fig. 5 and Fig. 6).In this example, drive division 23 uses motor 23a described later to make reverse roll 22 rotations.Drive division 23 can make reverse roll 22 with respect to package P contact free or move (with reference to Fig. 4 and Fig. 7) with leaving.In this example, drive division 23 uses air actuator 23d described later that reverse roll 22 is moved.Drive division 23 drives according to the control signal from control part 40.Control part 40 can be controlled drive division 23.

Guide portion 24 can catch the spinning Y that is truncated and be directed to assigned position (with reference to Fig. 5 and Fig. 6).Guide portion 24 possesses the spinning Y that can catch package P side and is directed to the first guide portion 24a of assigned position, can catches the second guide portion 24b that is directed to assigned position from the spun spinning of spinning section 3 one sides Y.Action form aftermentioned about the first guide portion 24a and the second guide portion 24b.

The yarn end of the spinning Y that connector portions 25 will be truncated be engaged with each other (with reference to Fig. 6).Detailed description is that connector portions 25 will be closed by the yarn end of the spinning Y of the first guide portion 24a guiding with by the yarn termination of the spinning Y of the second guide portion 24b guiding.Wherein, " the spinning Y that is truncated " is for comprising at least the concept that is cut off the spinning Y that device 41 cuts off and has applied the spinning Y that unusual tension force is disconnected.Connector portions 25 will be spinned the air splicing device that the yarn end of Y is engaged with each other except adopting with the turn air-flow, can also adopt mechanical type device of splicer etc.

Like this, because Mobile workbench 20 possesses braking parts 21, reverse roll 22, drive division 23, guide portion 24 and connector portions 25, therefore simplifying the structure of each spinning unit 10 can be made, simplifying the structure of spinning machine 100 can be made.

Then illustrate that with reference to Fig. 3 to Fig. 7 spinning unit 10 is from interrupting this a series of operation that makes that begins to restarting this package P that makes of package P.In Fig. 3 to Fig. 7, the arrow of blacking represents to consist of the direction of action of each parts of spinning unit 10 and Mobile workbench 20, and hollow arrow represents the direction of rotation of package P.

Spinning unit 10 uses the cutter 41 Y cut-out of will spin when yarn defect test section 4 detects the defect point of spinning Y.Thus, the end of the spinning Y that is truncated (than the spinning Y of cutter 41 by the downstream) is wound up on the package P.The other end of the spinning Y that is truncated (than the cutter 41 spinning Y by upstream side) is inhaled near the diagram abridged that are arranged on the cutter 41 and attracts mouthful to keep.

Then, spinning unit 10 makes reel cage 62 rotations make package P leave (with reference to the arrow of blacking Fig. 3) from driven roller 61.Thus, package P continues rotation (with reference to the hollow arrow among Fig. 3) under the inertia force effect.In addition, Mobile workbench 20 will spin to walk immediately after Y cuts off at cutter 41 and arrive this spinning unit 10.

Then, Mobile workbench 20 uses braking parts 21 that the rotation of package P is stopped.Specifying as, Mobile workbench 20 rotates arm 21b makes plate 21a contact (with reference to the blacking arrow among Fig. 3) with the outer peripheral face of package P.Like this, Mobile workbench 20 utilizes the friction between package P and the plate 21a that the rotation of this package P is stopped.

Then, Mobile workbench 20 uses reverse roll 22 that package P is reversed.Mobile workbench 20 reverses for the spinning Y that the first guide portion 24a can be caught be wound up on the package P makes package P.At first, Mobile workbench 20 makes arm 21b rotation make plate 21a leave (with reference to the blacking arrow Fig. 4) from the outer peripheral face of package P.Then, Mobile workbench 20 makes reverse roll 22 contact with package P and makes this package P reverse.Specify for, it is contact position (with reference to the blacking arrow Fig. 4) to the position that contacts with package P that Mobile workbench 20 makes reverse roll 22 namely leave position movement from the position of leaving package P.Then, Mobile workbench 20 makes reverse roll 22 rotations make package P reverse (with reference to the hollow arrow among Fig. 4).In addition, the details aftermentioned of relevant drive division 23.

The external diameter that control part 40 makes the contact of reverse roll 22 and package P and package P mutually independent, for roughly controlling definitely drive division 23.Even in the different situation of the external diameter of package P, also can dwindle the difference of the contact of reverse roll 22 and package P.Thus, can prevent that the distortion of package P or the quality that is wound up into the spinning Y on the package P from worsening.

Then, Mobile workbench 20 uses guide portion 24 to catch the spinning Y that is truncated and is directed to assigned position.Specify for, the first guide portion 24a from position of readiness downwards (downstream of spinning direction of travel) rotate, catch the spinning Y(that is wound on the package P with reference to the blacking arrow among Fig. 5).The first guide portion 24a rotates under suction is keeping spinning the state of Y upward, and the Y that will spin is directed to assigned position (with reference to the blacking arrow among Fig. 6).The second guide portion 24b catches from the 3 spun spinning Y(of spinning section with reference to the blacking arrow Fig. 5 from upward (upstream side of spinning direction of travel) rotation of position of readiness).The second guide portion 24b rotates downwards under suction is keeping spinning the state of Y, and the Y that will spin is directed to assigned position (with reference to the blacking arrow among Fig. 6).

Then, Mobile workbench 20 will by the first guide portion 24a be directed to assigned position spinning Y the yarn end and closed by the yarn termination that the second guide portion 24b is directed to the spinning Y of assigned position.

Then, spinning unit 10 restarts making of package P.Spinning unit 10 makes reel cage 62 rotations make package P move (with reference to the blacking arrow among Fig. 7) along the direction near driven roller 61.At this moment, Mobile workbench 20 leaves the position and makes reverse roll 22 leave (with reference to the blacking arrow Fig. 7) from package P by reverse roll 22 is moved to from contact position.Therefore, reverse roll 22 soon with before driven roller 61 contacts leaves package P at package P.That is, control part 40 usefulness reel cages 62 move package P, with control drive division 23 before driven roller 61 will soon contact reverse roll 22 are left at this package P from package P.

In the spinning machine 100 since after reverse roll 22 leaves package P this package P contact with driven roller 61 immediately, so package P can unexpected reverse.The Y that can prevent from thus spinning is lax.

Follow structure and action form with reference to Fig. 8, Fig. 9 A and Fig. 9 B explanation drive division 23.In Fig. 8, Fig. 9 A and Fig. 9 B, the blacking arrow represents to consist of the direction of action of each parts of drive division 23.

Drive division 23 possesses motor 23a, arm 23b, sub-arm 23c, air actuator 23d and bar 23e.

Motor 23a is installed in the end of arm 23b.In this example, motor 23a is servomotor.Motor 23a also can be stepping motor etc., and kind without limits.

Arm 23b is rotated freely centered by turning cylinder SH1 to be installed.In arm 23b is upper the first belt wheel 23ba and the second belt wheel 23bb are housed.The first belt wheel 23ba is rotated by motor 23a.The second belt wheel 23bb is rotated by the conveyer belt 23bc that volume hangs on this second belt wheel 23bb and the first belt wheel 23ba.

Sub-arm 23c rotates centered by turning cylinder SH2 freely and installs.The 3rd belt wheel 23ca and four-tape wheel 23cb is housed on sub-arm 23c.The 3rd belt wheel 23ca is installed on upper the second in-built belt wheel 23bb of arm 23b.Four-tape wheel 23cb is rotated by the conveyer belt 23cc that volume hangs on this four-tape wheel 23cb and the 3rd belt wheel 23ca.Rotating shaft at four-tape wheel 23cb is equipped with reverse roll 22.

Air actuator 23d possesses cylinder 23da, piston 23db and piston rod 23dc.When the air of sending here from air supply source (not shown) offered cylinder 23da, piston 23db was to slide near the direction of package P (with reference to Fig. 9 B).Thus, the piston rod 23dc that is installed on the piston 23db slides with piston 23db, makes bar 23e rotate (with reference to Fig. 9 B) to the direction away from package P.As a result, reverse roll 22 namely leaves position movement (with reference to Fig. 9 B) to the position of leaving package P.When the air in the cylinder 23da was inhaled into vacuum lines (not shown), piston 23db was to slide away from the direction of package P (with reference to Fig. 9 A).Thus, the piston rod 23dc that is installed on the piston 23db slides with piston 23db, makes bar 23e rotate (with reference to Fig. 9 A) to the direction near package P.As a result, reverse roll 22 is that contact position moves (with reference to Fig. 9 A) to the position that contacts with package P.That is, air actuator 23d is reciprocating type air actuator.

Bar 23e rotates centered by the pin P1 of the piston rod 23dc of air actuator 23d freely and installs.Bar 23e rotates freely installation centered by being arranged on the pin P2 on the sub-arm 23c.The end (first end) of bar 23e is installed on the piston rod 23dc, and the other end (the second end) of this bar 23e is installed on the sub-arm 23c.

The following describes the action form of drive division 23.Action form when at first making reverse roll 22 and package P contacts with Fig. 9 A explanation.

Control part 40 sends to not shown electromagnetic valve etc. with control signal and makes air sucking-off in the cylinder 23da.Thus, piston 23db is slided, and the piston rod 23dc that is installed on this piston 23db moves along the direction of keeping out of the way in the cylinder 23da.Therefore, air actuator 23d rotates the bar 23e that is installed on the piston rod 23dc.

Bar 23e rotates sub-arm 23c centered by turning cylinder SH2, arm 23b is rotated centered by turning cylinder SH1.Specify for because sub-arm 23c rotates centered by turning cylinder SH2 and freely be installed with, so follow the rotation of bar 23e and rotate.Because arm 23b rotates centered by turning cylinder SH1 with sub-arm 23c and freely is installed with, so follow the rotation of bar 23e and rotate.Like this, drive division 23 moves reverse roll 22, and this reverse roll 22 is contacted with package P.

Then, control part 40 sends to not shown relay etc. with control signal and makes motor 23a energising.Thus, reverse roll 22 begins rotation, and the package P that is in this reverse roll 22 contact conditions also begins rotation.

Then use Fig. 9 B that the action form that makes when reverse roll 22 leaves package P is described.

Control part 40 sends to the power supply that not shown relay etc. cuts off motor 23a with control signal.Thus, reverse roll 22 stops the rotation, and the package P that is in contact condition with this reverse roll 22 also stops the rotation.

Then, control part 40 sends to not shown electromagnetic valve etc. with control signal air is offered cylinder 23da.Thus, piston 23db slides, and the piston rod 23dc that is installed on this piston 23db moves along out direction in cylinder 23da.Air actuator 23d rotates the bar 23e that is installed on the piston rod 23dc.

Bar 23e rotates sub-arm 23c centered by turning cylinder SH2, arm 23b is rotated centered by turning cylinder SH1.Specify for because sub-arm 23c rotates centered by turning cylinder SH2 and freely be installed with, so follow the rotation of bar 23e and rotate.Because arm 23b rotates centered by turning cylinder SH1 with sub-arm 23c and freely is installed with, so follow the rotation of bar 23e and rotate.Like this, drive division 23 moves reverse roll 22, and this reverse roll 22 is left from package P.

Like this, the drive division 23 of this example uses air actuator 23d that reverse roll 22 is moved.Thus, spinning machine 100 can be controlled accurately and make reverse roll 22 leave the period of package P.Therefore, owing to can this package P be contacted with driven roller 61, so package P can unexpectedly not reverse.Thus, the Y that can prevent from spinning is lax.

And, even in the different situation of the external diameter of package P, also can dwindle the difference of the contact of reverse roll 22 and package P.Thus, can prevent that the distortion of package P or the quality that is wound up into the spinning Y on the package P from worsening.

The structure of spinning section 3 then is described with reference to Figure 10.Spinning section 3 is for utilizing the turn air-flow with the so-called open end spinning apparatus of fiber bundle F twisting.In Figure 10, the arrow of blacking represents the throughput direction of fiber bundle F and spinning Y, and hollow arrow represents the flow direction of the air supplied with.

Spinning section 3 forms the turn air-flow by the air stream that sprays from nozzle sets 33 in spinning room SC, with this turn air-flow fiber bundle F is twisted.Spinning room SC be divided into be formed in the space S C1 between fiber guide device 31 and the spindle 32 and be formed in spindle 32 and nozzle sets 33 between space S C2.

In space S C1, the rearward end of the fiber of formation fiber bundle F is by turn air-flow inverting (with reference to the double dot dash line among Figure 10).In space S C2, the rearward end of the fiber that has overturn is by turn flow rotation (with reference to the double dot dash line among Figure 10).By the turn flow rotation the fiber fiber that is wound up in rapid succession central part get on.Like this, spinning section 3 can spin spinning Y with fiber bundle F twisting.

Spinning section 3 possesses pin 31n in fiber guide device 31.Pin 31n is directed to fiber bundle F among the fiber channel 32h, prevents that simultaneously the sth. made by twisting of fiber bundle F from propagating into upstream side.But pin 31n also can omit.

Like this, because spinning unit 10 possesses the spinning section 3 that fiber bundle F is twisted with the turn air-flow of air, therefore can improve the manufacturing efficient of the spinning Y of each spinning unit 10, can improve the production efficiency of the package P of spinning machine 100.

The spinning machine 100 of an example of the present invention more than has been described, but the present invention is not limited to above-mentioned example, said structure for example can be altered to following structure.

Braking parts 21, reverse roll 22, drive division 23, guide portion 24 and connector portions 25 are arranged in the Mobile workbench 20 in the above-mentioned example, but also can be arranged in each spinning unit 10.Also the drive division of drawing-off section 2 and the drive division of winder 6 can be set independently in each spinning unit 10, in the operation of independently reeling of each spinning unit 10.

Control a plurality of spinning units 10, Mobile workbench 20 and the chassis 30 that doff with control part 40 in the above-mentioned example, but also the unit controls section that controls individually each spinning unit 10 can be set in each spinning unit 10.At this moment, control part 40 is all together a plurality of spinning units 10.

Cut off with cutter 41 Y that will spin in the above-mentioned example, but also can interrupt by the manufacturing of the spinning Y that stops spinning section 3 to be carried out to the supply of the air of spinning section 3, by the Y cut-out of will spinning like this.

With air actuator 23d reverse roll 22 is moved in the above-mentioned example, but also can reverse roll 22 be moved with motor or cam mechanism.

Above-mentioned example Air actuator 23d adopts reciprocating type air actuator, but also can reverse roll 22 be moved with force application parts such as single-lift air actuator and springs.For example can use single-lift air actuator to make reverse roll 22 move to contact position, the force application parts such as use spring move to reverse roll 22 and leave the position.The force application parts such as spring change owing to applying the displacement of power because of force application part, therefore become greatly with the difference of the different reverse rolls 22 of the external diameter of package P with the contact of package P.So preferred reciprocating type air actuator of air actuator 23d.
