Use the shape of Fig. 4 A and Fig. 4 B pair roller main body 60 to describe.Fig. 4 A represents the lateral plan of roller main body 60.Fig. 4 B represents the birds-eye view of observing from yarn moving direction downstream of roller main body 60.Roller main body 60 forms, and possesses upstream side flange part (upstream flange) 62 as second flange part, winding portion 63 and as the downstream flange part (downstream flange) 64 of first flange part.Upstream side flange part 62 and downstream flange part 64 have the dip plane of mitigation, and the dip plane of this mitigation is along with towards the upstream of yarn moving direction or each end face side in downstream and hole enlargement.Winding portion 63 forms by the concentric circles that is made of roughly the same diameter, jointlessly forms continuously with upstream side flange part 62 and downstream flange part 64.From the spun yarn Y of roller main body 60 unwindings, with unwinding when the diameter of downstream flange part 64 is contacted by the part of maximum hole enlargement, and move towards the downstream in downstream guiding piece 41.
In addition, winding portion 63 can not form by the concentric circles that is made of roughly the same diameter yet.Particularly, winding portion 63 also can form the taper that diameter diminishes towards the downstream along with the upstream side from the circumvolution of beginning spun yarn Y.In addition, the package portion 63 that forms taper also can constitute, cone angle along with before the side downstream so that interim slow down and.Particularly, also can form, the cone angle in the upstream side awl zone of winding portion 63 is littler than the cone angle in awl zone, downstream.In addition, the quantity in the awl zone of winding portion 63 also is not limited to upstream side awl zone and awl zone, downstream 2, and the awl zone also can form 3.
On the downstream of roller main body 60 flange part 64 (being designated hereinafter simply as flange part 64), be formed with a plurality of (being 4 in the present embodiment) planar portions (planar portion) 65 and a plurality of (being 4 in the present embodiment) curved face part (curved surface portion) 66.On flange part 64, planar portions 65 and curved face part 66 alternately form respectively, do not form continuously respectively.In addition, the quantity of planar portions 65 on the flange part 64 and curved face part 66 is not limited to present embodiment.Particularly, the quantity of planar portions 65 and curved face part 66 also can be respectively more than 3 or 5.That is,, can prevent that thus spun yarn Y from floating from flange part 64, and be wound on the S. A. that yarn stockpiles device 24 by 3 planar portions 65 and planar portions 66 are set respectively at least.
Formed 4 planar portions 65 on the flange part 64, mutual opposed planar portions 65 forms and is parallel to each other, and the elongated surfaces of adjacent planar portion 65 forms mutually orthogonal mutually.Formed 4 planar portions 65 are to be processed as smooth formation by 4 positions with flange part 64 on the flange part 64.
In addition, being parallel to each other and the relation of quadrature of formed planar portions 65 on the flange part 64 is not limited to present embodiment.But, opposed planar portions 65 is equated from the distance of S. A. separately.In addition, the distance from S. A. is different separately to make adjacent planar portion 65.
Then, about the shape of flange part 64, use the profile 64L of the multiview drawing of observing from the axial downstream side of roller main body 60 to describe.The profile 64L of the multiview drawing of observing from the axial downstream side of roller main body 60 forms roughly as different curvature portion that line part 65L and a plurality of (in the present embodiment being 4) curve part 66L of linearity form by a plurality of (in the present embodiment being 4).Roller main body 60 from the multiview drawing that the axial downstream side is observed, do not comprise the flange part 64 of upstream side.Line part 65L is the part of above-mentioned planar portions 65 having been carried out projection from the axial downstream side of roller main body 60.Curve part 66L is the part of above-mentioned curved face part 66 having been carried out projection from the axial downstream side of roller main body 60.In addition, line part 65L is not limited to and forms roughly linearity, so long as the little circular arc of curvature of the circular arc of ratio of curvature profile 64L gets final product.
The combined length of line part 65L forms below 1/2 of circumference (comprising line part 65L in interior whole circumference) of profile 64L.In addition, the total of the neutral angle of line part 65L (is the string at the center neutral angle when observing as the center shaft 60A with roller main body 60 with line part 65L) forms below 180 degree.In the profile 64L of flange part 64, above-mentioned line part 65L excises and forms toroidal.
As described above owing on flange part 64, be formed with planar portions 65, so spun yarn Y with when flange part 64 contacts from 60 unwindings of roller main body.When spun yarn Y contacted with planar portions 65, spun yarn Y floated from flange part 65, and the tension force of spun yarn Y reduces and relaxes.But when spun yarn Y contacted with curved face part 66, the spun yarn Y of institute's unwinding contacted with flange part 64 (curved face part 66) and the tension force recovery, suppressed the lax of spun yarn Y.That is, during hanging that yarn parts 72 winding yarns stockpile that roller 39 circles, be repeated below phenomenon: the tension force of spun yarn Y reduces the corresponding number of times of quantity with planar portions 65, and the tension force of spun yarn Y recovers the corresponding number of times of quantity with curved face part 66.So, even tension force reduces, tension force also can recover soon afterwards, so can reduce the situation that the spun yarn Y that moves floats from the flange part 64 of roller main body 60 on flange part 64.Therefore, can reduce spun yarn Y and enter chance between the flange part 64 of hanging yarn parts 72 and roller main body 60.Thereupon, can also prevent that spun yarn from stockpiling the insufficiency that the circumvolution etc. of the roll shaft of roller 39 causes to yarn.
For example, about the flange part of roller main body, the yarn that forms elliptical shape at the profile of the multiview drawing of observing from the axial downstream side of roller main body stockpiles the device, and curvature changes along the whole circumference of profile.Therefore, during hanging that yarn parts winding yarns stockpiles that roller circles, the tension force of spun yarn reduces in minor axis portion, and spun yarn also can float from the flange part that yarn stockpiles roller sometimes.On the other hand, stockpile in the device 24, on flange part 64, be formed with planar portions 65 at the yarn of present embodiment.Therefore, during hanging that yarn parts 72 winding yarns stockpile that roller 39 circles, repeat the reduction and the recovery of spun yarn Y tension force, spun yarn Y can not float from the flange part 64 that yarn stockpiles roller 39.
In addition, be that the yarn of elliptical shape stockpiles in the device at the flange part of roller main body, spun yarn is sometimes from the knocking over of roller main body in minor axis portion.On the other hand, stockpile in the device 24 at the yarn of present embodiment, planar portions 65 cedes territory to be provided with at the Zhou Shangfen that yarn stockpiles roller 39.That is, compare with the situation of elliptical shape, to become the unsettled time shorter for spun yarn Y in a planar portions 65.Therefore, stockpile in the device 24, can avoid that spun yarn Y stockpiles the situation that roller 39 breaks away from from yarn when being in planar portions 65 at the yarn of present embodiment.
Use Fig. 5 to describe to hanging relatively rotating between yarn parts 52 and the roller main body 60.In Fig. 5, when hanging yarn parts 52 and rotate relatively, represent, represent with long and two-short dash line when being positioned at planar portions 65 with solid line when hanging yarn parts 52 and being positioned at curved face part 66 with respect to roller main body 60.At this, the rotational trajectory of hanging yarn parts 52 is circular, and the profile 64L that yarn stockpiles the flange part 64 of roller 39 is the polygon that comprises curve part 66L and line part 65L.
By becoming this formation, when stockpiling axially (being the direction vertical) observation of roller 39 among Fig. 5 from yarn with respect to paper, yarn stockpiles the intersection point of profile 64L and the flier 72 of hanging yarn parts 52 of the flange part 64 of roller 39, and is different when being positioned at curve part 66L when hanging yarn parts 52 and be positioned at line part 65L.In other words, stockpile the difference of the position of rotation of roller 39 with respect to yarn according to hanging yarn parts 52, and above-mentioned intersection point difference.Yarn stockpiles the spun yarn Y of institute's circumvolution on the roller 39, with move when the flange part 64 of roller main body 60 contacts, and with move when the flier 72 of hanging yarn parts 52 contacts, and pulled on the axis that yarn stockpiles roller 39 towards downstream guiding piece 41.
Using Fig. 6 that spun yarn Y is stockpiled roller 39 from yarn is described by the state of unwinding.In Fig. 6, when being positioned at curve part 66L, extension yarn parts 52 represent with solid line, when being positioned at line part 65L, extension yarn parts 52 represent with long and two-short dash line.When hanging yarn parts 52 and stockpile roller 39 and rotate relatively with respect to yarn, hang the spun yarn Y position contacting of yarn parts 52 and institute's unwinding, between width D, change.
By becoming this formation, hang yarn parts 52 and become not necessarily with spun yarn Y position contacting, have Rack D ground and change.Therefore, for the mobile abrasion that cause of spun yarn Y, in hanging yarn parts 52, wear away and can not develop partly, and can improve the life-span of hanging yarn parts 52.Therefore, can reduce make spinning machinery 20 stop, owing to hang yarn parts 52 because of unfavorable conditions such as abrasion fracture exchange the situation of hanging yarn parts 52, can improve the capacity rating of package YP.
So, the shift position that hangs the spun yarn Y on the yarn parts 52 is changed all the time.And the spun yarn Y that reduce to move stockpiles the situation that the flange part 64 of roller 39 floats from yarn, and reduces spun yarn Y and enter the chance of hanging between the flange part 64 that yarn parts 52 and yarn stockpile roller 39.Therefore, can prevent that spun yarn Y from stockpiling the insufficiency that circumvolution etc. causes on the roll shaft of roller 39 to yarn.
