It is mobile, overhang of the angle guiding device 52 from suction port 42 can be changed.
The top end part 52b of angle guiding device 52 is to be located at upside in the top end part of suction nozzle 31 --- it is located at aftermentioned yarn end
The part in the downstream side in the direction of rotation P (uncoiling direction) is wrapped when capture.Top end part 52b is equivalent to " downstream side of the invention
End ".It is provided with yarn on the surface of the top end part 52b of the angle guiding device 52 and captures assisted parts 54.Yarn captures auxiliary
The frictional resistance on 54 surface of portion is bigger than the frictional resistance of the channel wall of the 1st channel part 43.As shown in fig. 6, yarn captures auxiliary
Portion 54 is by keeping yarn end Ya the catching come auxiliary yarns end Ya here when the capture of the yarn end Ya for carrying out upper yarn Y2 in suction nozzle 31
It catches.Yarn captures assisted parts 54 to be continued via the top end face 52c near the package surface P of 52 top end part 52b of angle guiding device
To 43 side of the 1st channel part (uncoiling direction upstream side) face 52d and with 43 opposite side of the 1st channel part (uncoiling direction downstream
Side) face 52e and extend.
Yarn is described in detail below and captures assisted parts 54.Fig. 7 be provided with yarn capture assisted parts 54 angle draw
Lead the enlarged partial sectional view of 52 top end part 52b of device.As shown in fig. 7, it includes to be formed in angle guidance that yarn, which captures assisted parts 54,
The metal envelope 55 of 52 top end part of device.Metal envelope 55 has with certain thickness basal layer 55a and respectively from the basal layer
55a multiple minute protrusions portion 55b outstanding.
Metal envelope 55 is formed by metallising.The metal of the surface injection heating melting of present dynasty's angle guiding device 52
Deng with mobility metal material fine particle when, the countless particles of injection are attached to the surface of angle guiding device 52, stand
I.e. natural cooling solidifies.At this point, a part of particle is to solidify before diffusion on the surface of angle guiding device 52, become multiple
Lug boss 55b.Also, the other parts of particle solidify in the state of along the diffusion into the surface of angle guiding device 52, become basis
Layer 55a.Basal layer 55a plays the role of for multiple lug boss 55b being fixed on the surface of angle guiding device 52.In this way, by
Be formed simultaneously in basal layer 55a and multiple lug boss 55b with identical metal material, thus basal layer 55a and lug boss 55b it
Between bonding strength it is high.Also, by adjusting the condition of metallising, the metals such as the size of lug boss 55b can be suitably changed
The surface shape of envelope 55.
As sprayed metal material, it is suitble to using such as nickel system metal material, tungsten system (tungsten carbide) metal material.And
And the material of the angle guiding device 52 of spraying plating object is it is not also specifically limited, but be suitble to use stainless steel and other metal materials.Separately
It outside, can be right before metallising in order to improve the basal layer 55a of metal envelope 55 and the adhesive strength of angle guiding device 52
The surface of 52 top end part 52b of angle guiding device carries out the surface treatment such as blasting treatment, by the surface roughening of angle guiding device 52.
If the yarn end Ya of upper yarn Y2 is contacted with the metal envelope 55 that yarn captures assisted parts 54, due to the fiber of yarn
It stumbles on multiple lug boss 55b of metal envelope 55, therefore yarn end Ya is readily retained in yarn and captures on assisted parts 54.Separately
Outside, in order to make the fiber of yarn be easy to stumble, preferably make the surface roughness of metal envelope 55 Ra (arithmetic average roughness:
Using JIS-B0601 as standard) in the range of 4~20.Also, the film thickness of metal envelope 55 is not particularly limited, but nickel system metal
The film thickness of envelope is 80 μm or so, and the film thickness of tungsten system metal envelope is 120 μm or so.
Then, illustrate effect when suction nozzle 31 carries out the yarn end capture of yarn Y2.As shown in figure 4, the upper yarn of the package side P
The yarn end Ya of Y2 is wound up on package P and is attached to surface.If the upper yarn driven by motor 27 captures guide member 24 and returns
It is screwed into the yarn end catching position indicated in Fig. 3 with double dot dash line, then the table of the suction port 42 of the suction nozzle 31 of its top end part and package P
Face is face-to-face.At the same time, opposite when making traversing drum 18 along with package winding with drum drive motor 28 in winder 13
Direction of rotation low speed rotation rotates package P along the i.e. uncoiling direction in the direction of rotation opposite with coiling direction.By
This, is wrapped in the yarn end Ya on package P from package P extraction, and sucked from suction port 42 and capture guide portion by upper yarn
Part 24 captures.
But when suction nozzle 31 captures yarn end Ya, following 3 kinds of situations can be generated by dividing in terms of big.
(situation 1: yarn end Ya is attracted the case where mouth 42 normally attracts) Fig. 8 is inhaled for expression in suction nozzle meduim yarn end Ya
The figure for the state drawn.The yarn end Ya of upper yarn Y2 is from the upstream side in uncoiling direction close to suction port 42.As shown in figure 8, from opening
The case where mobile next yarn end Ya in the upstream side in volume direction is intactly attracted to the 1st channel part 43 from suction port 42
Under, the yarn end Ya being attracted is hooked on the holding section 45a of plate component 45.Inhibit the yarn end Ya once being attracted as a result,
It is extracted again to the strength attachment on the package surface P as package P is rotated to uncoiling direction caused by being tangled etc. due to yarn hair
Outside is arrived, as a result the capture success rate of yarn end Ya improves.
Wherein, surface of the top end part of plate component 40 than the top end part 52b of angle guiding device 52 from package P is remote.Therefore, such as
As being indicated by the arrow A in Fig. 8, the air flowed from the upstream side in uncoiling direction to suction port 42 is easy to flow from suction port 42
Enter the 1st channel part 43, unlike this, the air flowed shown in arrow B from the downstream side in uncoiling direction to suction port 42 is by angle
Degree guiding device 52 blocks, it is not easy to flow into the 1st channel part 43 from suction port 42.That is, air is easy from the upstream side in uncoiling direction
Import suction port 42.Therefore, it is easy to be attracted close to the yarn end Ya of suction port 42 from the upstream side in uncoiling direction.
Yarn captures the angle guiding device 52 positioned at uncoiling direction downstream side that 31 top end part of suction nozzle is arranged in assisted parts 54
Top end part 52b on.Therefore, when from uncoiling direction upstream side, mobile next yarn end Ya is attracted by suction suction port 42, yarn end
Portion Ya does not capture assisted parts 54 with yarn and contacts, and yarn, which captures assisted parts 54, will not become the obstacle for attracting yarn end Ya.
(situation 2: yarn end Ya captures the case where assisted parts 54 contacts with yarn) Fig. 9 draws for expression yarn end Ya with angle
The yarn for leading 52 top end part 52b of device captures the figure for the state that assisted parts 54 contacts.That is, Fig. 9 is yarn end Ya close to suction port
42 but the case where be not inhaled into suction port 42.Yarn captures assisted parts 54 and is arranged in than suction port 42 by uncoiling direction downstream
The top end part 52b of the angle guiding device 52 of side.Also, the top end part 52b of angle guiding device 52 is located at the top than plate component 40
Portion is on the position on the surface of package P.Therefore, it is not inhaled into the yarn end Ya of suction port 42 and is arranged in angle guiding device
The yarn of 52 top end part 52b captures assisted parts 54 and contacts.If yarn end Ya captures assisted parts 54 with yarn and contacts, yarn end
The fiber of Ya stumbles on multiple lug boss 55b of the metal envelope 55, and yarn end Ya is kept here.
If kept here in the state that yarn captures assisted parts 54 in yarn end Ya, package P is rotated along uncoiling direction, then
It is taken off from the surface of package P the part of the yarns Y being attached on the package surface P being connected with yarn end Ya.Also, if package
P continuation is rotated along uncoiling direction, then tension becomes larger in the Ya of yarn end, and yarn end Ya is detached from yarn and captures assisted parts 54.
When yarn end, Ya leaves yarn capture assisted parts 54, by acting on attraction, yarn end Ya can be drawn into
Draw in mouth 42.Also, even if in the case where yarn end Ya is not inhaled into suction port 42 in this stage, when P is hereafter wrapped
Continuation is rotated along uncoiling direction, when yarn end Ya is again from the upstream side in uncoiling direction close to suction port 42, attract once by
The yarn end Ya for the state taken off.Therefore, yarn end Ya was easy to be attracted the attraction of mouth 42 than last time.That is, being captured by yarn
Assisted parts 54 certainly keeps yarn end Ya here, improves the capture success rate of yarn end Ya.
In addition, since yarn captures the top near package P that 52 top end part 52b of angle guiding device is arranged in assisted parts 54
On the 52c of end face, therefore yarn end Ya is easy to contact with yarn capture assisted parts 54.Moreover, because yarn capture assisted parts 54 from
The face 52d of the uncoiling direction upstream side of 52 top end part 52b of angle guiding device continues under uncoiling direction via above-mentioned top end face 52c
It swims the face 52e of side and is arranged, therefore even if tampering in yarn end Ya, yarn end Ya connects with the place for leaving above-mentioned top end face 52c
When having touched, yarn end Ya is also easy to contact with yarn capture assisted parts 54.
Moreover, because yarn captures the width that assisted parts 54 runs through suction port 42 in the top end part 52b of angle guiding device 52
The endlong extension in direction, therefore no matter yarn end Ya is located at which part that the surface P is wrapped, and can make yarn end Ya and yarn
Line captures assisted parts 54 and contacts.
(situation 3: the part other than the Ya of yarn end is attracted the case where mouth 42 attracts) Figure 10 is expression in 31 meduim yarn of suction nozzle
The figure for the state that thread segment other than the Ya of end is attracted.It is interrupted in cutter 22a cutting continuous strand, in package winding process
When yarn or when replacement supply bobbin 8, since the tension of upper yarn Y2 declines, the part near the yarn end Ya of upper yarn Y2
Yarn Y2 is loose in appearance, heaves slack Yb to outside.Therefore, slack Yb is attracted to from suction port 42 sometimes
In 1 channel part 43.At this point, if the slack Yb being attracted reaches holding section 45a, the engaged part slack Yb 45a hook
If having hung, then captures upper yarn when in order to which the slack Yb of the yarns Y captured is directed to piecing devices 21 and guide
When component 24 circles round, yarns Y is cut off, and the yarn bits being cut off have been retained on the surface of package P.Alternatively, when catching yarn
When catching guide member 24 and circling round, slack Yb is not directed to piecing devices 21 not cut-offly, slack Yb and lower yarn Y1 into
Connector processing is gone.That is, not carrying out normal connector.
If slack Yb is attracted to the 1st channel part 43 from suction port 42 in this implementation form, simultaneously such as Figure 10
Shown slack Yb is contacted with the top end part 52b of angle guiding device 52.Wherein, the top end part 52b of angle guiding device 52 compares plate
The top end part of component 40 is projected into the package side P.Therefore, even if slack Yb is attracted to the 1st channel part from suction port 42
43, the slack Yb being attracted also is not easily accessible to holding section 45a.
Also, such as Figure 10, when slack Yb has been attracted, slack Yb captures assisted parts 54 with yarn and connects
Touching.It is kept here as in the case where yarn captures assisted parts 54 with the yarn end Ya previously illustrated, even if in slack Yb
Keep here in the state that yarn captures assisted parts 54, rotated by package P along uncoiling direction, upper yarn Y2 with slack Yb phase
It is taken off from the surface of package P part even.Therefore, when package P is rotated along uncoiling direction, yarn end Ya is again adjacent to suction port 42
When, it is easy to capture yarn end Ya.
In addition, angle guiding device 52 can be mounted on the plate component 41 of suction nozzle main body 51 with taking out in this implementation form.
It therefore, can by taking out angle guiding device 52 in the worn out situation of metal envelope 55 that yarn captures assisted parts 54 etc.
It is easy to carry out the replacement that yarn captures assisted parts 54.
Also, suction nozzle 31 has suction nozzle main body 51 and angle guiding device 52 in this implementation form, and angle guiding device 52 can
It is movably installed relative to suction nozzle main body 51.Thereby, it is possible to make angle guiding device 52 relative to suction nozzle main body 51 along the left and right of Fig. 6
The positional relationship that direction is mobile, both changes can correspondingly change angle guiding device 52 from attraction with the type of yarns Y etc.
The overhang of mouth 42.
For example, the case where the type for the yarns Y being wrapped on package P is to be not easy from the yarn that suction port 42 attracts
Under, make plate component 45 (holding section 45a) close to the surface of package P.The yarn end Ya being attracted as a result, is hooked into holding section 45a
On become easy, can be improved the capture success rate of yarn end Ya.Conversely, the type in the yarns Y being wrapped on package P is not
In the case where being easy the yarn attracted from suction port 42, make the top end part 52b of angle guiding device 52 close to the surface of package P.By
This, yarn end Ya is contacted with the yarn capture assisted parts 54 being arranged on angle guiding device 52 and is become easy, as a result, can be improved
The capture success rate of yarn end Ya.
As explained above, in this embodiment, yarn capture assisted parts 54 include have basal layer 55a and
From the metal envelope 55 of basal layer 55a multiple lug boss 55b outstanding.It is contacted when yarn end Ya captures assisted parts 54 with yarn
When, the fiber of yarn is stumbled by multiple lug boss 55b of metal envelope 55.Therefore, with by etching etc. in angle guiding device 52
Surface on form recessed portion and compared the case where becoming male and fomale(M&F), yarn end Ya rests on yarn and captures to be become on assisted parts 54
It is easy.Also, since multiple lug boss 55b are securely fixed on angle guiding device 52 by basal layer 55a, prevent protrusion
Portion 55b's falls off.
Also, it since 55 intensity of metal envelope is high, wearability is good, is worn compared with the situation for using sand paper etc. small.
Also, in the case where sand paper etc. is pasted on angle guiding device 52 with adhesive, adhesion strength is weaker, peel resistance
Difference.In contrast to this, resistance to since the metal envelope 55 formed by metallising is high to the adhesive strength of angle guiding device 52
Fissility is good.According to the difference of condition, the adhesive strength of the metal envelope 55 that is formed by metallising to angle guiding device 52
It is the decades of times of the adhesive strength for the sand paper pasted with adhesive.As described above, metal envelope 55 is due to wear resistance and resistance to stripping
From property height, therefore durability is good, and replacement frequency is small.Also, due to the intensity of metal envelope 55 height, even if in yarn
In the case that the dust such as bits, finish are attached on yarn capture assisted parts 54, it can also be wiped with brush etc. and remove dust.
Also, in this implementation form, due to capturing yarn end Ya when assisted parts 54 contacts when yarn end Ya and yarn
It keeps here and is become easy in yarn capture assisted parts 54, therefore the capture success rate of the yarn end Ya of the progress of suction nozzle 31 improves.Pass through
It improves and captures success rate, the time required for acting the progress connector of piecing devices 22 shortens.

The substance that the metal material of 65a is high, wear resistance is good, for example, being suitble to use ceramic material.
The metal envelope 65 of Figure 11 can be formed with various galvanoplastic.For example, adding in the electroplate liquid comprising metal component
Add the shot-like particle 66 of ceramics etc., then metal material is attached on the surface of angle guiding device 52 by being electroplated.At this point, granular
Object 66, which is attached on angle guiding device 52 together with metal material, becomes lug boss 65b.Also, metal material is surrounding shot-like particle
In the state of attachment become basal layer 65a, shot-like particle 66 is securely fixed on angle guiding device 52.Also, electrolysis plating
It can be used with electroless plating.That is, no matter angle guiding device 52 is the object formed with the conductor for flowing through electric current, or use
Without flow through the object that the insulator of electric current is formed, metal envelope 65 can be formed on angle guiding device 52.
