Then, counter-rotating driver train 49 is described.Shown in Fig. 2 waited, counter-rotating driver train 49 had the first supporting arm 61, the second supporting arm 62, counter-rotating roller 63 and as the counter-rotating roller CD-ROM drive motor (omitting diagram) of the drive source of described counter-rotating roller 63.
One of described the first supporting arm 61 is distolaterally installed in the mode that can rotate with respect to the framework main body that connects yarn chassis 3.Described the second supporting arm 62 can be installed rotatably another of the first supporting arm 61 is distolateral.Front end at the second supporting arm 62 can be provided with described counter-rotating roller 63 rotatably.Connect yarn chassis 3 and have the union lever 64 that can arrange rotationally with respect to this framework that connects yarn chassis 3.The front end of union lever 64 and the second supporting arm 62 link.At union lever 64 counter-rotating roller advance and retreat cylinder 66 is installed.Can make union lever 64 rotations with the advance and retreat of cylinder 66 by counter-rotating roller advance and retreat.
Consist of connect mechanism by the first supporting arm 61, the second supporting arm 62 and union lever 64.By the described counter-rotating roller advance and retreat that are connected with this connect mechanism are carried out extension and contraction control with cylinder 66, can make counter-rotating roller 63 advance and retreat of the front end of the second supporting arm 62.Thus, can make the movement between " retreating position " that contact with package 45 (for example position shown in Figure 2) and " contact position " (for example position shown in Figure 5) of contacting with package 45 of counter-rotating roller 63.In addition, counter-rotating roller advance and retreat are controlled by described chassis control part with the action of cylinder 66.
Below, the yarn operation that connects of docking yarn chassis 3 describes.This connects the yarn operation in certain spinning unit 2, and the textile yarn 10 between spinning apparatus 9 and the package 45 carries out when becoming off-state because of some reason.
In certain spinning unit 2, for example shown in Figure 4, when the textile yarn 10 between spinning apparatus 9 and the package 45 becomes off-state, the cell controller of this spinning unit 2 carries out wobble drive to reel cage arm 71, and control so that package 45 from reel spool 72 away from, and make the not shown stop mechanism action that wind2 13 has.Thus, package 45 is stopped the rotation.
Then, described cell controller transmits control signal to connecing yarn chassis 3.The yarn chassis 3 that connects that receives control signal moves to described spinning unit 2 and stops connecing yarn chassis moving guide rail 41.Connect yarn feeding device 43 and be positioned at job position.When connecing yarn chassis 3 and move between spinning unit 2, mobile member 30 makes in advance and connects yarn feeding device 43 and keep out of the way retreating position.Suppose to connect yarn feeding device 43 when yarn chassis 3 moves and march to the position that approaches with the yarn road connecing, then the described yarn feeding device 43 that connects contacts with textile yarn 10 that each spinning unit 2 is being reeled and yarn may occur thus breaks.Make when connecing yarn chassis 3 and moving, make in advance connect yarn feeding device 43 keep out of the way from the yarn road away from position (retreating position), thus, can prevent that this from connecing yarn feeding device 43 and contacting with textile yarn 10.
After connecing yarn chassis 3 and stopping at target spinning unit 2, the chassis control part makes respectively suction pipe 44 and suction nozzle 46 rotations as illustrated in fig. 5, attracts also to catch the yarn ends of spinning apparatus 9 sides and the yarn ends of package 45 sides.
At this moment, the chassis control part makes counter-rotating roller 63 march to contact position, and the opposite sense rotary actuation of roller 63 to reel spool 72 that will reverse.Thus, package 45 is by reversing sense (hereinafter referred to as the unreeling direction) rotary actuation to coiling direction.Under this state, attract the textile yarn 10 on package 45 surfaces by suction nozzle 46, thus, this textile yarn 10 is pulled out from package 45, and is caught by suction nozzle 46.
Then, the chassis control part rotates round about by suction pipe 44 and the suction nozzle 46 that makes the state that captures textile yarn 10, the described textile yarn that captures 10 is guided to the position (state of Fig. 6) of facing with the face side that connects yarn feeding device 43.Mobile member 30, until the guiding that 46 pairs of textile yarns of suction pipe 44 and suction nozzle 10 are implemented finish during, make to connect yarn feeding device 43 in the retreating position standby.By make in advance connect yarn feeding device 43 keep out of the way from the yarn road away from the position, can prevent that the suction pipe 44 and the suction nozzle 46 that rotate from contacting with the described yarn feeding device 43 that connects.
After the guiding of suction pipe 44 and 46 pairs of textile yarns 10 of suction nozzle finished, the chassis control part stopped the rotation of counter-rotating roller 63.Then, mobile member 30 makes cylinder 38 be stretched over the limit of trip distance, makes thus to connect yarn feeding device 43 and move and advance to the direction near the yarn road and connect the yarn position.Connect yarn feeding device 43 and advance to and connect the yarn position, thus, the textile yarn 10 of package 45 sides that the textile yarn 10 of spinning apparatus 9 sides that suction pipe 44 catches and suction nozzle 46 catch is directed to and connects yarn feeding device 43 (state of Fig. 7).Like this, according to present embodiment, connecing yarn feeding device 43 self can be near the yarn road, textile yarn 10 is imported to this connects yarn feeding device 43 and makes the yarn road significantly crooked thereby be no longer necessary for.Under the state (the yarn road is unbending state almost) in yarn road that can be when approaching conventional the coiling textile yarn 10 imported to and connect yarn feeding device 43.
Because there is the limit in the trip distance of cylinder 38, can be mobile above described trip distance ground so connect yarn feeding device 43.That is to say, cylinder 38 self has the function of the stop mechanism that positions as the mobile terminal locations (connecing the yarn position) that docks yarn feeding device 43.Being used for connecing the backstopping assembly that yarn feeding device 43 is positioned to connect the yarn position also can arrange with cylinder 38 splits ground.
Shown in Fig. 7 waits, dispose and connect yarn section monitoring device 47, make at mobile member 30 to connect yarn feeding device 43 and advance to when connecing the yarn position, textile yarn 10 is directed to this and connects yarn section monitoring device 47.Thus, can check textile yarn 10 by connecing yarn section monitoring device 47.Like this, self can be near the yarn road, so do not need for textile yarn 10 being imported to the parts that connect yarn section monitoring device 47 owing to connecing yarn section monitoring device 47.Shown in Fig. 2 waited, when mobile member 30 makes when connecing yarn feeding device 43 and keeping out of the way retreating position, textile yarn 10 was not directed to and connects yarn section monitoring device 47.Thus, prevented from connecing the yarn road that connects yarn section monitoring device 47 and textile yarn 10 when yarn chassis 3 moves and interfering making.
Connect yarn feeding device 43 advance to connect the yarn position after, the chassis control part rotates guide bar 96 and contacts with textile yarn 10.Thus, the textile yarn 10 between the textile yarn 10 between package 45 and the suction nozzle 46 and spinning apparatus 9 and the suction pipe 44 is the bending by guide bar 96 respectively, and the yarn road of this textile yarn 10 is limited.Guide bar 96 guides to this textile yarn 10 position (state of Fig. 8) that can grip by clamping section 97 textile yarn 10.The chassis control part is closed clamping section 97 under this state, thus, grip textile yarn 10 by this clamping section 97.In addition, in the present embodiment, owing to being arranged on, the parts (guide bar 96) that are used for guiding textile yarn 10 connect yarn feeding device 43, so, connect yarn feeding device 43 and advance to when connecing the yarn position when mobile member 30 makes, guide bar 96 also advances to the position that approaches with the yarn road.Therefore, can by guide bar 96 reliably textile yarn 10 is guided to connect yarn mouth 94 connect yarn hole 90.Also advance to the position that approaches with the yarn road owing to connecing yarn mouth 94, must be by the distance of guide bar 96 guiding textile yarns 10 so can shorten, can reduce yarn road that textile yarn 10 is guided to when connecing yarn hole 90 crooked.
Then, the chassis control part is so that come into effect to untwisting tube 82 interior ejection pressurized airs.Thus, in untwisting tube 82, produce the air-flow towards the back side that connects yarn feeding device 43 routine (the figure right side of face of Fig. 8), and produce the attraction air-flow at the peristome of the front of this untwisting tube 82 example (the drawing left side of Fig. 8).Before and after it was implemented, the chassis control part made cutter 92 actions, cut off respectively suction pipe 44 and connect textile yarn 10 and the suction nozzle 46 between the yarn feeding device 43 and connect textile yarn 10 between the yarn feeding device 43.The yarn ends that forms by described cut-out is attracted by untwisting tube 82 respectively, and is pulled into the inside of this untwisting tube 82.The yarn ends that is drawn into is subject to the effect of the air-flow in the untwisting tube 82 and the twisting of untiing fiber, thereby by backtwisting (Fig. 9).
When the backtwisting of yarn ends finishes, the chassis control part so that pressurized air finish to the ejection of untwisting tube 82 inside.And the chassis control part makes the yarn road of textile yarn 10 further crooked by guide bar 96 and presser bar 98, and pulls out by the yarn ends of backtwisting from untwisting tube 82.The state (Figure 10) that the yarn ends of pulling out from untwisting tube 82 is connecing connecing of yarn mouth 94 and is configured to overlap in the yarn hole 90.Under this state, to connecing yarn hole 90 interior ejection pressurized airs, connect yarn hole 90 interior generation swirling eddies at this thus, fiber is applied twisting.Thus, the yarn ends of the textile yarn 10 of the yarn ends of the textile yarn 10 of spinning apparatus 9 sides and package 45 sides is by the combination of twisted ground, thereby formation meets yarn section 99.
After formation met yarn section 99, the chassis control part made air stop to the ejection that connects yarn hole 90.And the chassis control part is opened clamping section 97 and the textile yarn 10 that is held is decontroled, and removes the restriction in guide bar 96 and 98 pairs of yarn roads of presser bar.Before and after it was implemented, the cell controller of spinning unit 2 swung reel cage arm 71, and makes the outer peripheral face of package 45 contact (state of Figure 11) with the reel spool 72 of rotation.Thus, the package 45 that stops to begin the rotation to coiling direction again, can begin the coiling of textile yarn 10 again.
In the spinning frame 1 of present embodiment, connect yarn feeding device 43 and self closely connect yarn with respect to the yarn road.As shown in figure 11, the yarn road state (almost not having crooked state) in the time of yarn road when beginning again to reel textile yarn 10 being become approach conventional the coiling.Therefore, connect the knot bundle after, the lax Min. that is suppressed to of textile yarn 10 that can be when beginning again to reel textile yarn 10.
When beginning again the coiling of textile yarn 10, as shown in figure 12, by meeting the yarn section 99 that connects that yarn feeding device 43 forms by connecing yarn section monitoring device 47.At this moment, this meets yarn section 99 and is connect 47 inspections of yarn section monitoring device.The chassis control part is judged the quality that meets yarn section 99 based on the check result that connects yarn section monitoring device 47.For example, connect yarn section 99 for the bad situation that meets yarn section that does not satisfy regulation rugosity, length equidimension condition under, connect yarn chassis 3 and cut off and remove this bad yarn section that connects by omitting graphic cutter, and re-start and connect the yarn that connects that yarn feeding device 43 implements.
After the inspection that meets yarn section monitoring device 47 docking yarn sections 99 finished, mobile member 30 made and connects yarn feeding device 43 and move to retreating position.Thus, connecing yarn chassis 3 becomes the state that can move, thereby can move to other spinning units 2.In addition, make when connecing yarn feeding device 43 and keeping out of the way to retreating position at mobile member 30, be arranged on these guide bar 96 grades that connect in the yarn feeding device 43 and also keep out of the way to the position away from the yarn road.Owing to when not making guide bar 96 action, this guide bar 96 is kept out of the way, so can make the compact conformation that connects yarn chassis 3.
