The driving of first actuator 65 and second actuator 66 can be by control setup 83 (with reference to Fig. 1) control that the each several part of Yarn reeling device (automatic bobbin winder) 1 is controlled.When active side comb shape body 27 and active side pressing body 41 were carried out opening operation, the rotary power of first actuator 65 was passed to active side pressing body 41 and active side comb shape body 27 via first union lever 70, first bar 67 and the

body

20,21 that fluctuates etc.When from state-driven first actuator 65 of Fig. 3, Fig. 6 and Fig. 7; First bar 67 is that the center is shaken towards the dextrorotation direction of this figure with fulcrum 30, and active side pressing body 41 and active side comb shape body 27 switch from the control position shown in the above-mentioned figure towards position of readiness shown in Figure 4.

On the other hand; When active side comb shape body 27 and active side pressing body 41 were carried out shutoff operation, the rotary power of first actuator 65 was passed to active side pressing body 41 and active side comb shape body 27 via first union lever 70, first bar 67, second bar 68 and the

body

20,21 that fluctuates etc.When from state-driven first actuator 65 of Fig. 4, first bar 67 is that the center is shaken towards the left hand direction of Fig. 4 with fulcrum 30, and its second operating portion 74 is connected to an end of second bar 68 and second bar 68 is shaken around fulcrum 30.Then; Follow therewith; What the elastic body 79,78 of second bar 68 was connected to the

body

20,21 that fluctuates is made two

rock bodies

20,21 shake around same fulcrum 30 by operating

portion

61,33; Thus, active side pressing body 41 and active side comb shape body 27 switch towards control position from position of readiness.

When active side pressing body 41 and active side comb shape body 27 arrival control positioies, second actuator 66 is driven.The rotary power of this second actuator 66 is passed to active side pressing body 41 and active side comb shape body 27 via second union lever 72, second bar 68 and the body 20,21 that fluctuates etc., thereby the control position of active side pressing body 41 and active side comb shape body 27 is further regulated knifeedge.As a result, like Fig. 2 and shown in Figure 6, movable broach 34 intersects with the state of fixed fingers 28 with regulation, and yarns Y with in the crooked mode clamping of left and right directions indentation, utilizes the friction force that acts on this curve to give pulling force to yarns Y by two broach 28,34.And; Like Fig. 2 and shown in Figure 7; Above two broach 28,34 that intersect; Yarns Y be clamped in fixation side pressing body 40 the yarn contact part (the first yarn contact part) 49 that constitutes by circular-arc protuberance and and the yarn contact part (the second yarn contact part) that likewise constitutes of active side pressing body 41 between 51 by circular-arc protuberance, when yarn is advanced, nuzzle up and the filoplume of yam surface is broken at this retained part in the surface through yarns Y.

Control setup 83 is according to from the determination data of pulling force sensor 6 voltage (electric current) that puts on second actuator 66 being controlled; Thereby the torque value to acting on active side pressing body 41 and active side comb shape body 42 is regulated, so that the pulling force of yarns Y, suitable by the pressing force to yarns Y of first, second

yarn contact part

49,51 generations.The pulling force of yarns Y is the driving of second actuator 66 to be controlled according to the mensuration result of pulling force sensor 6 through control setup 83 to regulate.

In the Yarn reeling device 1 that constitutes in the above described manner; Be positioned under the state of control position at active side pressing body 41 and active side comb shape body 27; When yarns Y being advanced towards the top of Fig. 1 so that form package P from the confession spool B by bobbin support 3 supporting towards reeling end 9 coiling yarns Y, yarns Y is wound in reeling end 9 under the state of having been given needed pulling force by tightening device 10.In this process,, therefore can produce the different filoplume of length on surface through the yarns Y after the tightening device 10 from the undercoat plumage below the 1mm to the plumage that becomes mildewed more than the 10mm because yarns Y partly waits with thread-carrier and contacts.

The yarns Y that has produced such filoplume after through tightening device 10 through be disposed at tightening device 10 above filoplume remove device 11, at this moment, the above long filoplume of 3mm is removed in the following manner.That is the yarns Y of, advancing along the yarn travel path be clamped in filoplume remove the yarn contact part 49 of a pair of pressing

body

40,41 that device 11 possessed, between 51.Then, under this state, when yarns Y through yarn contact part 49, between 51 the time, give friction force to the filoplume that is present in yam surface, filoplume is broken and is removed.

At this moment; Be clamped in yarn contact part 49, the pressing force (Clamping force) of yarns Y between 51 and cross when strong when acting on, the yam surface roughen is fluffed on the contrary, when wide with respect to the area of contact of yarns Y; The distance of nuzzling up of yam surface is elongated, also can become the reason of fluffing.Though the pulling force by first actuator 65 is given via rock body 21 and 27 pairs of yarns Y of active side comb shape body of downside is constant; And the pressing force that acts on yarns Y via the rock body 20 and the active side pressing body 41 of upside in order to remove filoplume is also constant; But when using the protuberance clamping yarns Y of point point, the area that contacts with yarns Y is very little; Therefore pressure (Clamping force) can concentrate on this part, thereby can fluff on the contrary because of the strong pressing force that concentrates on this part causes the yarn roughen.And then, when the filoplume recruitment that causes because of this fluffing than being broken the filoplume reduction that causes because of filoplume for a long time, the single-piece filoplume amount increases.On the contrary, when the area that contacts with yarn was excessive, the concentrated of pressure (Clamping force) can disappear, and can't obtain needed pull-off force.In addition, become big amount correspondingly with the area that contacts with yarns Y, the distance that yam surface is nuzzled up is elongated, thereby causes fluffing to increase.This because of filoplume broken the filoplume reduction that causes and the difference of the filoplume recruitment that causes because of fluffing determined as final filoplume amount, can't obtain sufficient filoplume in respect to yarn face contacting structure and remove effect but remove mechanism at filoplume.

Relative therewith; Remove in the device 11 at the filoplume of said structure; With the first and second yarn contact part 48,49 up and down of a pair of pressing body 40,41 of the mode arranged opposite that clips the yarn travel path and 50,51 by constituting the yarns Y of utilizing these opposed protuberances to come clamping to advance along the circular-arc protuberance that extends with the direction of the travel path quadrature of yarns Y.In this case; Though the words that are in direct contact with one another when opposed circular-arc protuberance can form the curved surface contact; But when the direction of edge and two protuberance quadratures the yarns Y of advancing between these two protuberances by the state of these two protuberance clampings through between this protuberance the time, this yarns Y is to be similar to a line contact condition that contacts with contact condition between this protuberance.When this yarns Y being advanced with the line contact condition that is similar to a contact when yarns Y being clamped between the circular-arc protuberance of the interval that separates regulation like this at two positions up and down; Although the area that contacts with yarns Y is smaller, can not cause the concentrated of pressure (Clamping force) when coming the clamping yarn as protuberance with point point.Therefore in addition,, can access needed pull-off force because the area that contacts with yarns Y is smaller, simultaneously, the increase of the elongated fluffing that causes of distance that can avoid nuzzling up because of yam surface.In addition, for long filoplume, with the long amount of its length accordingly, the friction force through the yarn effect between the circular-arc protuberance is also become greatly, so compares more easily with the undercoat plumage and to be broken.Like this, remove device 11 and possess the Yarn reeling device 1 that this filoplume is removed device 11, can remove and even be suppressed at the long filoplume (filoplume more than the 3mm) that batches in the yarns Y generation of package P effectively according to above-mentioned filoplume.
