Search engine 61 also can independently follow for yarn bobbin 10 surface concavo-convex decline.Thereby, it is possible to improve for yarn bobbin 10
Yarn ends stripping success rate.
Herein, it is different from present embodiment, even if two supporting members 63 are configured to by individual other direct acting bearing branch
Hold as that can be moved along with the opposed direction for yarn bobbin 10, and exerted a force towards for yarn bobbin 10 by individual other spring,
Two search engines 61 can be made independently to follow the concavo-convex of the surface for yarn bobbin 10.But, direct acting bearing and swivel bearing phase
Can be higher than general component cost.For example, in the present embodiment, four swivel bearings are used in a stripping unit 51
64a, 64b, but there is a component cost for direct acting bearing than four situations of the component high cost of swivel bearing.Additionally, straight
Dynamic bearing has that the ability being mixed into of tolerance flyings is weaker, poor durability compared with swivel bearing.Therefore, in this reality
Apply in mode, each stripping unit 51 is configured to, the end of a side of linkage component 64 is searched with supporting via swivel bearing 64a
The supporting member 63 for seeking device 61 rotatably links, and via swivel bearing 64b by the end of the opposing party of linkage component 64
Rotatably link with movable frame 42, exerted a force using 65 pairs of linkage components of a side 64 of spring.Thus, the straight line of spring 65
Active force be converted into linkage component 64 swaying direction power, by the power by search engine 61 towards exerting a force for yarn bobbin 10.
So, in the present embodiment, direct acting bearing is not used and uses swivel bearing to constitute stripping unit 51, therefore, it is possible to suppress stripping
From the component cost of unit 51.It is further possible to improve the durability of the stripping unit 51 being mixed into relative to flyings.
Additionally, now, as shown with arrow A in Fig. 9, air is sprayed from air blower 62.Thus, the yarn after stripping
Line end is blown afloat upward by the air sprayed from air blower 62.Due to being rotated for yarn bobbin 10, so the yarn for being blown afloat
End is wound in the upper end of core pipe 10a.
Also, work as makes movable frame 42 drop to the position near the lowest point of the scope that can be lifted using cylinder body 43
When, two projection 63b of stripping unit 51 are contacted with the cam surface 46a of two cam parts 46.When making activity box from the state
When frame 42 further declines, then as shown in Figure 10, projection 63b is guided by the cam surface 46a of cam part 46, thus supporting member 63
The active force of spring 65 is overcome to be moved towards away from the direction for yarn bobbin 10.Thus, search engine 61 is away from for yarn bobbin 10.That is,
In the present embodiment, the decline of supporting member 63 is converted into supporting member 63 towards away from the side for yarn bobbin 10 by cam part 46
To movement.Now, projection 63b is guided and moved by the cam surface 46a of cam part 46, and thus, search engine 61 can be in regulation
The decline of moment and movable frame 42 cooperatively reliably moved towards away from the direction for yarn bobbin 10.
Herein, it is different from present embodiment, it is also considered that to drive cylinder body 52 and make pressing plate 53 towards away from for yarn bobbin 10
Direction is moved, and supporting member 63 is moved towards away from the direction for yarn bobbin 10.However, it is very difficult to control cylinder body 52 to cause pressing
Plate 53 is lentamente moved.On the other hand, if making pressing plate 53 quickly mobile, search engine 61 is rapid away from for yarn bobbin 10.
In this case, there is a possibility that search engine 61 upsets the thread layers on the surface for yarn bobbin 10, therefore be undesirable.This
Outward, when as described later search engine 61 is returned to upward using cylinder body 43, if search engine 61 is contacted with for yarn bobbin 10,
Then the hang part 61a of search engine 61 nips the surface for yarn bobbin 10.Therefore, in the present embodiment, as described above, when utilization
When cylinder body 43 makes search engine 61 reach lowest point, the projection 63b of supporting member 63 is guided using the cam surface 46a of cam part 46,
Thus search engine 61 is made to be reliably separated from the surface for yarn bobbin 10 in the timing of regulation.In addition, now, search engine 61 is towards phase
For the direction that is slightly tilted of direction with the surface normal for yarn bobbin 10 away from the surface for yarn bobbin 10.
Then, after movable frame 42 is moved to the lowest point of the scope that can be lifted, as shown in figure 11, cylinder body is being utilized
After 52 make pressing plate 53 be moved to the position contacted with projection 63a, movable frame 42 is increased using cylinder body 43 and return to Fig. 3
The position of~Fig. 5.
