Row explanation.
Show that open end spinning apparatus 9 is generated spun yarn 10 and batched in rolls using devices for taking-up 13 in spinning unit 2 in Fig. 2
Fill 45 common state.In this condition, cell controller 60 is controlled to carry out sliver 15 using drafting system 7
Drawing-off is simultaneously supplied towards open end spinning apparatus 9, and is controlled to generate using the progress open-end spinning of open end spinning apparatus 9
Spun yarn 10.Hereinafter, the action of the drafting system 7 under the usual state shown in Fig. 2 is referred to as into usual spinning sometimes to act.
It will describe below, when the draw ratio of the drafting system 7 during usual spinning action as usual spinning according to acting
The thickness of the spun yarn 10 of generation and the thickness that utilizes the input unit 32 of body control device 30 to set is determined.From open end spinning apparatus
9 be sent after spun yarn 10 by yarn qualities monitoring arrangement 52, detect the presence of yarn defect.Then, spun yarn 10 is by towards yarn storage
Device 12 is conveyed.
Cell controller 60 is controlled that yarn excision bar 28 is maintained at into decline under the usual state shown in Fig. 2
Position.Thus, the one side of spun yarn 10 is guided while being temporarily stored in yarn storage roller 21 towards extension yarn part 22.Spun yarn 10 is relative
Suitably adjusted by the coiling speed of the package 45 in suitable control devices for taking-up 13 in the storage capacity of yarn storage roller 21.From
Spun yarn 10 after yarn storage roller 21 is unwind coils into package 45 by devices for taking-up 13.
If yarn qualities monitoring arrangement 52 is detected has yarn defect on spun yarn 10, yarn defect is sent towards cell controller 60
Detect signal.Spinning of the cell controller 60 if yarn defect detection signal is received by stopping being carried out by open end spinning apparatus 9
And cut off spun yarn 10, and further stop the action of the grade of drafting system 7.After spinning stops, cell controller 60 is carried out
Control removes spun yarn 10 from yarn storage roller 21 to make yarn storage roller 21 rotate or invert.As a result, as in yarn
The state of spun yarn 10 is not stored on storage roll 21 completely.
Then, the butt joint chassis 3 of cell controller 60 sends control signal, it is marched to the spinning unit 2.Then,
Cell controller 60 drives drafting system 7 and open end spinning apparatus 9 etc. again.Hereinafter, sometimes by drafting system 7 now
Action is referred to as spinning reopening action.
When usual spinning is acted, spinning unit 2 generates the spun yarn 10 of the thickness set using input unit 32.In spinning
Reopening act when, spinning unit 2 because it is aftermentioned the reasons why and independently generate medium count yarn (such as 30 with the setting in input unit 32
Yarn) spun yarn 10.Thus, such as in the case where setting the spun yarn 10 of generation fine-count yarn using input unit 32, generally spinning
The draw ratio of drafting system 7 is set to the draw ratio suitable with fine-count yarn when yarn is acted, and generates the spun yarn 10 of fine-count yarn, another
Aspect, when spinning reopening action, the draw ratio of drafting system 7 is changed to predetermined draw ratio, generation medium count yarn (it is specific and
Say as 30 yarns) spun yarn 10 (the 1st pattern).On the other hand, generation medium count yarn (30 yarns) is being set using input unit 32
Spun yarn 10 in the case of, under the either case when usual spinning is acted and during spinning reopening action, drafting system 7 is led
Stretch than being all configured to the draw ratio (2nd pattern) suitable with medium count yarn.The details of the control of the draw ratio will later
Narration.
After spinning reopening action starts, the loose thread (upper yarn) for the spun yarn 10 sent out from open end spinning apparatus 9 is such as Fig. 4 institutes
Show and attracted by the suction nozzle 44 for turning to top, caught.Then, suction nozzle 44 turns to lower section, as shown in fig. 7, upper yarn is by towards sth. made by twisting
Device 43 is connect to guide.Be accompanied by this, from open end spinning apparatus 9 be drawn out after the hooking as shown in Figure 7 of spun yarn 10 in hang yarn part 22,
Spun yarn 10 is set gradually to batch in yarn storage roller 21 as shown in Figure 8 by the extension yarn part 22 of rotation.
With this substantially simultaneously (before or after can also being), the one side of cell controller 60 utilizes reversion dress (not shown)
Putting makes package 45 invert and unwind yarn under working from package 45, is attracted as shown in Figure 4 using the suction inlet 46 for turning to lower section on one side
And catch the yarn under working.Then, suction inlet 46 turns to top as shown in Figure 7, and yarn under working is guided towards splicer 43.
If by the scheduled time since being wound in yarn storage roller 21 spun yarn 10, as having been store in yarn storage roller 21
Have the state of the spun yarn 10 of more than necessary minimum storage capacity length, then the control of cell controller 60 drafting system 7, so as to
Draw ratio during usual spinning action carries out drawing-off to fibre bundle 8.I.e., spinning reopening above-mentioned in drafting system 7 action knot
Beam, switches to usual spinning action.Thus, the common spinning carried out by open end spinning apparatus 9 is started.Also, due at this
Moment winds the spun yarn 10 for the length being necessary more than minimum storage capacity on yarn storage roller 21, therefore spun yarn 10 is with stabilization
Tension force and speed are pulled out from open end spinning apparatus 9.Thus, be formed as the spinning stablized in open end spinning apparatus 9.
Even if starting to generate the spun yarn 10 of common quality as described above in open end spinning apparatus 9, in yarn storage roller
Although still being remained on 21 by spinning reopening action generation and the spun yarn 10 of thickness that is typically different or being and usual phase
With thickness but (being generated before the spun yarn 10 that necessary minimum storage capacity is wound on yarn storage roller 21) quality is unstable
Spun yarn 10.Therefore, cell controller 60 is controlled such that yarn extracts bar before it will switch to usual spinning action
28 position movements upward as shown in Figure 9.As a result, the spun yarn 10 for being wound in yarn storage roller 21 is unwound from yarn storage roller 21
And attracted by suction nozzle 44 and gone out of use.So, in the present embodiment, when spinning reopening action the spun yarn 10 that generates by will be upper
The suction nozzle 44 that yarn is guided towards splicer 43 is removed, therefore, it is possible to simplify the structure of spinning frame 1.
The spun yarn 10 that should be removed all from yarn storage roller 21 unwinding after, cell controller 60 is controlled such that yarn
Line extracts bar 28 as shown in Figure 8 towards down position movement.As a result, spun yarn 10 is contacted with hanging yarn part 22, in yarn storage roller 21
The storage capacity of spun yarn 10 gradually increase.
Then, joint is carried out with yarn under working using 43 pairs of upper yarns of splicer.Then, the common shape shown in Fig. 2 is returned
State, reopens the batching towards package 45 of spun yarn 10.
Secondly, the control of the draw ratio in counter extensioin device 7 and the yarn associated with the control extract the control of bar 28
