Then, unit controls section transmits the request signal that doffs to board control setup 12.The board control setup 12 that receives this request signal that doffs make doffer 14 advance to the full volume of package 18 winder unit 11 directly over the position and it is stopped in this position.When doffer 14 is advanced, in order not make yarn pull-out arm 36 and winder unit 11 collisions such as grade, make in advance this yarn pull-out arm 36 in position of readiness (position shown in Fig. 5 and Fig. 6) standby.Specifically, this position of readiness is the device face side end of the oscillating stroke of yarn pull-out arm 36 on first direction.
In addition, the 4th guiding piece 74 has the 3rd little slide unit 75 of friction drag in the part that contacts with yarn pull-out arm 36.Thus, because the 4th guiding piece 74 guides yarn pull-out arm 36 via the 3rd slide unit 75, therefore can prevent that yarn pull-out arm 36 from sustaining damage.And, as shown in Figure 5, at the partial configuration that contacts with the 4th guiding piece 74 of bar-like member 36b flexible pipe guard block 76 is arranged.As shown in Figure 7, this flexible pipe guard block 76 forms hollow shape, and constitutes and make air hose 45 be inserted through its inside.Thus, can prevent that air hose 45 from sustaining damage because contacting with the 4th guiding piece 74.
The doffer 14 that stops directly over winder unit 11 utilizes reel cage to open wide 37 pairs of reel cages 23 of arm and operates, and takes off the package 18 that reaches full volume from reel cage 23.Package 18 after being removed is mobile at the figure of the behind that is disposed at winder unit 11 conveyer slightly, and is carried towards next operation.Next, doffer 14 utilizes anchor clamps 38 to pick up a mound bobbins 22 of depositing in the sky in the bobbin receptacle 39, and this anchor clamps 38 are rotated, near the reel cage 23 that the mound bobbins 22 of described sky is moved to be under the opening-wide state.
In the front and back of moving based on the maintenance of 38 pairs of mound bobbins 22 of anchor clamps, doffer 14 moves so that be in yarn pull-out arm 36 elongation of position of readiness, makes thus the yarn of the front end that is installed on this yarn pull-out arm 36 catch 41 and drops to (Fig. 8) near the attraction mouth 31 of the lower yarn guiding tube 29 that is in described yarn delivery position.As previously mentioned, the yarn pull-out arm 36 that utilizes 74 pairs of the 4th guiding pieces to be in position of readiness positions.Because the 4th guiding piece 74 is the structures that contact with the thickest bar-like member 36b, so the 4th guiding piece 74 can not hinder the fore and aft motion of yarn pull-out arm 36.That is, yarn pull-out arm 36 can keep being stretched unchangeably by the state behind the 4th guiding piece 74 location.
Next, 14 pairs of drive divisions 47 of doffer drive, and yarn pull-out arm 36 is swung around the clockwise direction (towards the device rear side) of the first axial view 8.Herein, as shown in Figure 7, the 4th guiding piece 74 forms overlooks the roughly U word shape that the timer rear side is opened wide.Therefore, can be moved towards the device rear side in that the 4th guiding piece 74 is interior by the yarn pull-out arm 36 behind the 4th guiding piece 74 location.That is, can utilize the 4th guiding piece 74 guiding yarn pull-out arms 36 and this yarn pull-out arm 36 is swung towards the device rear side.
If yarn pull-out arm 36 swings to the position (position shown in Figure 9) that yarn capture unit 41 can be accepted the yarn 16 that lower yarn guiding tube 29 catches, then drive division 47 stops the swing of this yarn pull-out arm 36.The position of yarn capture unit 41 of this moment is called yarn accepts the position.Yarn accept the position be in described yarn delivery position near, be positioned at the upstream side of this yarn delivery position.
Accept the position at yarn, yarn capture unit 41 utilizes clamping section 42 to control near the lower yarn guiding tube 29 yarn 16, and utilizes cutter section 43 at the position cutting continuous strand 16 than the slightly top side in the position of controlling (downstream).Thus, the yarn of the yarn feeding bobbin side that keeps of lower yarn guiding tube 29 is joined the yarn capture unit 41 to doffer 14.
In addition, as previously mentioned, the lower yarn guiding tube of winder unit 11 29 originally is for yarn under the yarn 16(of yarn feeding bobbin 15 sides) be directed to the parts of Yarn connecting device 26.Therefore, the lower yarn guiding tube 29 that can say present embodiment have concurrently with lower yarn be directed to Yarn connecting device 26 parts, with these two kinds of functions that lower yarn joined to the parts of yarn capture unit 41.Like this, because parts have two kinds of functions concurrently, therefore can consist of simply winder unit 11.
And as previously mentioned, the doffer 14 of present embodiment forms following structure: utilize the 4th guiding piece 74 to come the swing starting position (position of readiness) of yarn pull-out arm 36 is positioned, while and utilize the 4th guiding piece 74 to guide to make yarn pull-out arm 36 to swing.According to this structure, while because the swing path that can limit yarn pull-out arm 36 swings this yarn pull-out arm 36, therefore can precision make well yarn capture unit 41 move to yarn and accept the position.Thus, can improve to the success ratio of yarn capture unit 41 handing-over yarns.
Yet, because yarn pull-out arm 36 is elongated parts, therefore exist the position of the yarn capture unit 41 of the front end that is installed on this yarn pull-out arm 36 to be easy to the such situation of the changing of the relative positions.And, even the swing path of yarn pull-out arm 36 is correct, when the stop position changing of the relative positions of doffer 14, because the also fully changing of the relative positions of the position of yarn capture unit 41, therefore to the sometimes failure of handing-over of the yarn of this yarn capture unit 41.The changing of the relative positions meeting of the stop position of such doffer 14 is being set in locating piece 66 lower generation of situation (setting mistake etc.) of departing from original position.And, in the situation of yarn pull-out arm 36 because of certain reason bending, the dislocation of yarn capture unit 41 also can occur.
Therefore, in the present embodiment, constitute: the 3rd guiding piece 73 by being arranged at yarn capture unit 41, with the engaging of the second guiding piece 72 that is arranged at winder unit 11, carry out yarn capture unit 41 is accepted the position at yarn location.
As shown in Figure 5, the 3rd guiding piece 73 is fixed in yarn capture unit 41, is configured to towards the device rear side outstanding.That is, the 3rd guiding piece 73 constitutes towards the outstanding protuberance of device rear side.On the other hand, shown in Fig. 9 waited, the second guiding piece 72 was disposed near (top of Yarn connecting device 26 during specifically, for side-looking) of the yarn delivery position of lower yarn guiding tube 29.In addition, the second guiding piece 72 is disposed at the position (specifically, being disposed at the side top of Yarn connecting device 26) of departing from the yarn road between yarn feeding bobbin 15 and the package 18 at the device left and right directions.Thus, when the common coiling of yarn 16, the second guiding piece 72 can not hinder advancing of yarn 16.
As shown in figure 10, be formed with slot part (recess) 77 at the second guiding piece 72, this slot part 77 is formed at roughly fore-and-aft direction of device.Thickness on the device left and right directions of the width on the device left and right directions of this slot part 77 and the 3rd guiding piece 73 is basic identical or reach bigger a little degree.And, the device face side of slot part 77 open ended, the end-enclosed of device rear side.
In above structure, the 3rd guiding piece 73 can engage with the slot part 77 of the second guiding piece 72.By engaging of this second guiding piece 72 and the 3rd guiding piece 73, can near the yarn delivery position of lower yarn guiding tube 29, (yarn is accepted the position) position yarn capture unit 41.Because the 3rd guiding piece 73 directly is arranged at yarn capture unit 41, therefore can be by precision positions yarn capture unit 41 well with engaging of the 3rd guiding piece 73.
And, as shown in figure 10, on the 3rd guiding piece 73 and in the part that contacts with the second guiding piece 72, the second slide unit 78 is installed.Therefore, the second guiding piece 72 engages via the second slide unit 78 with the 3rd guiding piece 73.Thus, can successfully carry out engaging and the releasing of this engaging of the second guiding piece 72 and the 3rd guiding piece 73.
And, as shown in figure 10, be formed with the V-shaped valley 79 of widening towards the device face side when overlooking at the second guiding piece 72.The end of the device rear side of this V Asian puccoon 79 is communicated with described slot part 77.According to this structure, can utilize V-shaped valley 79 guiding three guiding piece 73 next from installing the face side convergence and it is imported to the inboard of slot part 77.Thus, even how many to some extent changing of the relative positions on the device left and right directions of the position of the 3rd guiding piece 73 also can make the second guiding piece 72 engage with the 3rd guiding piece.Therefore, even for example in the situation of the stop position changing of the relative positions of doffer 14 or in the situation of yarn pull-out arm 36 bendings, the second guiding piece 72 is engaged with the 3rd guiding piece.Thus, owing to can position yarn capture unit 41 reliably, therefore can more improve towards the success ratio of the yarn handing-over of yarn capture unit 41.
In the structure shown in above, can utilize yarn capture unit 41 to accept reliably yarn under the yarn 16(of yarn feeding bobbin 15 sides).If yarn 16 is joined to yarn pull-out arm 36 from lower yarn guiding tube 29 in this mode, then doffer 14 utilizes drive division 47 that yarn pull-out arm 36 is swung around the anticlockwise direction of Fig. 9.Thus, form following state: with the engage releasing of the second guiding piece 72 with the 3rd guiding piece 73, and yarn pull-out arm 36 is positioned position of readiness again by the 4th guiding piece 74.
Next, doffer 14 moves so that yarn pull-out arm 36 shrinks, and extracts thus the yarn 16 of yarn feeding bobbin 15 out towards the top.And then 14 pairs of drive divisions 47 of doffer drive, and make yarn pull-out arm 36 swing near the position (shown in Figure 11 position) of yarn 16 from passing through the reel cage 23 that yarn capture unit 41 keeps.The yarn fixed position that this position is called yarn pull-out arm 36.
