Expansion link 4 has 41,3 upside 42,2 lower side rail components of track component of cartridge as shown in Figure 6 to 843, opening and closing member 44 etc..Cartridge 41 is the cylindric component being made of metal material etc..Also, in cartridge 41Delimit inner space 41a inner wall 41b in black (implement the silk thread Y for making to walk in the 41a of inner space it is easily eye-catching addWork).Inner wall 41b being capable of blackening for example, by implementing the blackened processing such as black alumina film process or smearing resin etc..At this point, both can only make inner wall 41b blackening, 41 blackening of entire cartridge comprising inner wall 41b can also be made.
Also, the both ends of the vertical direction in cartridge 41 are respectively arranged with flange part 46,47.Flange part 46,47It is stretched out from the outer peripheral surface 41c of cartridge 41 to the radial outside of cartridge 41.Also, in the front-rear direction of cartridge 41On nearly body side (side on the 2nd direction of the invention) sidewall portion, be formed with from the portion being located at immediately below flange part 46The opening portion divided the lower end for extending to the cartridge 41 provided with flange part 47 along the vertical direction, expose inner space 41a41d。
Wherein, cartridge 41 is the cylindrical portion of such as length 400mm of diameter 85mm or so, vertical direction or soPart, in contrast, opening portion 41d are formed in the circumferential direction of cartridge 41 throughout the range that central angle is 120 ° or so.ByThis, the width (length in orientation) of opening portion 41d is 72.2mm or so.Operator can be for example from opening as a result,3 or so fingers or the inner space 41a of repiece auxiliary member insertion cartridge 41 are carried out aftermentioned sub-wire by portion 41dOperation.
3 upside track components 42 are below flange part 46 along the circumferential array of cartridge 41.Each upside orbit portionThe outer peripheral surface 41c of part 42 and cartridge 41 cartridge 41 radially spaced apart gap 48a configure.Also, each upper siding trackRoad component 42 circumferentially face 41c throughout such as cartridge 41 90 ° of central angle or so of range extend.Also, in upsideThe upper end of track component 42, cartridge 41 circumferential central portion, be provided with to the radial outside of cartridge 41 and stretchMounting portion 42a out.Upside track component 42 is fixed on flange part 46 in mounting portion 42a using bolt 49a.
2 lower side rail components 43 configure with avoiding opening portion 41d in the upper surface of flange part 47.Each lower side rail component 43With the outer peripheral surface 41c of cartridge 41 cartridge 41 radially spaced apart gap 48b configure.Also, each lower side rail portionPart 43 circumferentially face 41c throughout such as cartridge 41 90 ° of central angle or so of range extend.Also, in lower side railThe lower end of component 43, cartridge 41 circumferential central portion, be provided with and stretch out to the radial outside of cartridge 41Mounting portion 43a.Lower side rail component 43 is fixed on flange part 47 in mounting portion 43a using bolt 49b.
Opening and closing member 44 on the outer peripheral surface 41c of cartridge 41 along the circumferentially extending of cartridge 41, and verticalDirection almost endlong extends throughout cartridge 41.Also, the upper-end part of driving of opening and closing member 44 is opened and closed in the 48a of gapThe lower end of component 44 is in the 48b of gap.That is, opening and closing member 44 upper end be clipped in the outer peripheral surface 41c of cartridge 41 withBetween track component 42, it is clipped between the outer peripheral surface 41c of cartridge 41 and track component 43 in lower end.Opening/closing portion as a result,Part 44 on outer peripheral surface 41c by the guidance of track component 42,43 along the circumferential of cartridge 41 by that can be slided.That is, opening/closing portionPart 44 can be relative to cartridge 41 along the circumferential direction sliding of cartridge 41.Also, as shown in Fig. 6 (a), Fig. 7 (a), ifOpening and closing member 44 is set to be moved to the position being completely coincident with opening portion 41d, opening portion 41d is closed due to being coated by opening and closing member 44It closes.Wherein, opening and closing member 44 extends in the circumferential direction of cartridge 41 throughout the range longer than opening portion 41d, at this point, openingPortion 41d is completely closed by opening and closing member 44.On the other hand, as shown in Fig. 6 (b), Fig. 7 (b), if being moved to opening and closing member 44The position not being overlapped with opening portion 41d, then opening portion 41d is not coated by opening and closing member 44, and opening portion 41d is opened.Also,On the part near part and lower end near the upper end of the outer peripheral surface of opening and closing member 44, it is respectively formed with along cartridgeThe reinforcing rib 44a of 41 circumferentially extending ensures the intensity of opening and closing member 44 by forming reinforcing rib 44a.
Wherein, in this implementation form, the more single fiber F to form 2 silk thread Y are spun from a spinning head 13, these are moreInner space 41a walking of the root single fiber F in a cartridge 41.At this point, formed sometimes different silk thread Y single fiber F thatThis sticks together.Therefore, in this implementation form, operator is by more single fiber F in 41 inner space 41a of cartridge pointsSilk to every silk thread Y sub-wire operation and become the operation in the silk thread Y repiece after sub-wire to corresponding oil supply guiding device 5 mustIt wants.At this point, there is no opening portion 41d on cartridge 41 if be different from the present invention, can not visual identity in inner spaceIf the silk thread Y of 41a walking, then carries out sub-wire operation and become difficult.
In this implementation form, if opening and closing member 44 is made to be moved to position not Chong Die with opening portion 41d as described above,If opening wide opening portion 41d, then operator can silk thread Y in side opening 41d visual identity inner space 41a,While inner space 41a is inserted into from opening portion 41d by finger or repiece auxiliary member, thus by more single fibers in the 41a of inner spaceF sub-wire is tieed up to every silk thread Y.Thereby, it is possible to be easy to carry out sub-wire operation.Also, at this time since silk thread Y (single fiber F) is logicalIt is often the color whitened, in contrast, the color of inner wall 41b is arranged to black, therefore is easy visual identity silk thread Y.
Moreover, in this implementation form, since opening portion 41d extends to the lower end of cartridge 41, for example from openingAfter finger or repiece auxiliary member insertion inner space 41a are carried out sub-wire operation by oral area 41d, it can make to be inserted into inner spaceThe finger or repiece auxiliary member of 41a moves directly to than cartridge 41 be able to carry out the repiece to oil supply guiding device 5 on the lowerOperation.Thereby, it is possible to be easy to carry out the repiece operation to oil supply guiding device 5.
Also, in this implementation form, is arranged by multiple expansion links 4 along orientation form column as described above, comparedUnder, the sidewall portion of the nearly body side on the front-rear direction of cartridge 41 for constituting each expansion link 4 is formed with opening portion41d.The sub-wire work that thereby, it is possible to carry out being related to these expansion links 4 from the nearly body side on the front-rear direction of multiple expansion links 4Industry.
Also, at this time on the front-rear direction of cooler bin 22 behind side be connected with pipeline 21, it is in contrast, each constitutingThe sidewall portion of nearly body side (side opposite with pipeline 21) on the front-rear direction of the cartridge 41 of expansion link 4 is formed with outOral area 41d.Therefore, when carrying out sub-wire operation, pipeline 21 will not become barrier.
On the other hand, it when without sub-wire operation, is completely coincident by being moved to opening and closing member 44 with opening portion 41dPosition, close opening portion 41d.So, the more single fibers due to walking between cooling device 3 and oil supply guiding device 5It is coated throughout complete cycle by cartridge 41 and opening and closing member 44 around dimension F, therefore in the silk thread Y to walk in inner space 41aAround, the Flowing Hard of air is to generate disorder.Thereby, it is possible to prevent the swing of single fiber F.Wherein, if single fiber F is generatedIt swings, then the silk thread quality of silk thread Y is brought to reduce.In this implementation form, since the pendulum of single fiber F can be prevented as described aboveIt is dynamic, therefore can prevent the silk thread quality of silk thread Y from reducing.
Also, in this implementation form, since opening and closing member 44 can be on the outer peripheral surface 41c of cartridge 41 along cylindrical portionThe circumferential sliding of part 41, therefore, It is not necessary to be used to make opening and closing member in opening portion 41d opening and closing around cartridge 4144 mobile broad space leeway.
Wherein, in this implementation form, multiple expansion links 4 as described above to form column by arranging along orientation.Moreover, plusThe column of long cylinder 4 are arranged in 2 column along the longitudinal direction, formed the column of nearly body side expansion link 4 and formed below the column of side plusLong cylinder 4 is in staggered configuration along orientation.Therefore, with the expansion link 4 of the column that form nearly body side and formation column of side belowExpansion link 4 is compared the case where overlapping from front-rear direction, between capable of reducing on front-rear direction between the column of expansion link 4Every.But in this case, the space leeway behind between the column of the expansion link 4 of the column of the expansion link 4 of side and nearly body sideBecome smaller.
But in this implementation form, there is no need for being opened and closed in opening portion 41d around cartridge 41 as previously describedWhen keep opening and closing member 44 mobile broad space leeway.Therefore, when opening portion 41d is opened and closed, opening and closing member 44 will not be with arrangementAdjacent expansion link 4 on direction, the expansion link 4 for forming the column of nearly body side on front-rear direction are interfered.
Then, illustrate the variation that various changes are applied with to this implementation form.
The position of the opening portion upper end 41d is not limited to above-mentioned implementation form.For example, it is also possible to which opening portion 41d is extended toThe upper end of cartridge 41.Alternatively, the upper end of opening portion 41d can also be located at the central portion of cartridge 41 on vertical directionDeng, with the above-mentioned implementation form the case where compared be located at the lower portion of cartridge 41.
Also, opening and closing member 44 can be on the outer peripheral surface 41c of cartridge 41 along cartridge in above-mentioned implementation form41 circumferential sliding, however, it is not limited to this.For example, such as Fig. 9 (a), (b) of variation 1 is shown, opening and closing member 66 is configured in tubularOn the inner wall 41b of component 41 and along the circumferentially extending of cartridge 41, while along the vertical direction throughout cartridge 41Endlong extend.Also, on inner wall 41b formed along cartridge 41 circumferentially extending guide rail 67, opening and closing member 66 withGuide rail 67 engages.Opening and closing member 66 can be on the inner wall 41b of cartridge 41 along cylinder and being guided by guide rail 67 as a result,The circumferential sliding of shape component 41.That is, opening and closing member 66 can be relative to cartridge 41 along the circumferential direction sliding of cartridge 41.
Moreover, opening and closing member is not limited to slide relative to cartridge 41 along the circumferential direction of cartridge 41.ExampleSuch as, variation 2 is as shown in Figure 10 (a), (b), swing of the opening and closing member 71 in the end of side to extend along the vertical directionSwinging centered on axis 72 freely carries.Wherein, the both ends of the vertical direction of swinging axle 72 be separately fixed at flange part 46,On the part of 47 opening portion 41d adjacent edges.In this case, if make opening and closing member 71 in terms of upside in the counterclockwise directionIf swing, then opening portion 41d can be closed as shown in Figure 10 (a).Also, if making the edge in terms of upside of opening and closing member 71If swinging clockwise, then opening portion 41d can be opened wide as shown in Figure 10 (b).But in this case, in cylinderThe space leeway that the nearly body side of shape component 41 needs the ratio for being used to swing opening and closing member 71 broader.
Although also, arranging the column formed along front and back along orientation by multiple expansion links 4 in above-mentioned implementation formDirection is arranged in 2 column, forms the expansion link 4 of the column of nearly body side and forms the expansion link 4 of the column of side below along orientationIt is in staggered configuration, however, it is not limited to this.For example, multiple expansion links 4 can also be arranged in 1 column along orientation.In addition, at theseIn the case of, to cooperate the configuration of multiple expansion links 4 also to change the configuration of multiple spinning heads 13 and multiple cooling cylinders 23.
Although also, in above-mentioned implementation form, on the front-rear direction of the cartridge 41 of each expansion link 4 with 21 phase of pipelineOpening portion 41d is formed in the sidewall portion of anti-side, however, it is not limited to this.For example, it is also possible in the cartridge of each expansion link 4Opening portion is formed in the sidewall portion of 21 phase the same side of pipeline (side behind above-mentioned implementation form) on 41 front-rear direction41d.Alternatively, opening portion 41d can also be formed in the sidewall portion in the orientation of the cartridge 41 of each expansion link 4.
Although also, the inner wall 41b of cartridge 41 is set for black in above-mentioned implementation form, does not limit toIn this.Inner wall 41b, which also can be implemented to be formed, becomes the saturate color (such as blue etc.) than silk thread Y other than blackOther processing that appearance etc. keeps silk thread Y eye-catching.
Although also, cooling device 3 is the cooling device of the CIQ type of cooling in above-mentioned implementation form, is not limited toThis.Cooling device 3 is also possible to the cooling device of the mode different from the CIQ type of cooling.
Although also, in above-mentioned implementation form, configuring oil supply guiding device 5 in the lower section of expansion link 4, configuring in expansion link4 lower sections are also possible to the filar guide different from the oil supply guiding device of finish is applied to single fiber F.
Also, although more single fiber F for constituting 2 silk thread Y are spun in above-mentioned implementation form from a spinning head 13,It is not limited thereto.The more single fiber F of the silk thread Y of composition 3 or more can also be spun from a spinning head 13.
Also, although silk thread Y is multifilament in above-mentioned implementation form, however, it is not limited to this.Silk thread Y is also possible to monofilament.Even in this case, when the radical from a spun silk thread Y (monofilament) of spinning head 13 is more, in cartridge 41Silk thread Y also sticks together each other sometimes in the 41a of portion space.In this case, operator, which has, carries out cartridge 41Necessity of the sub-wire operation of silk thread Y in the 41a of inner space.At this point, passing through Bian Congkai in the state of having opened wide opening portion 41dThe side silk thread Y in the inner space 41a of oral area 41d visual identity cartridge 41 carries out the sub-wire operation of these silk threads Y, canIt is easy to carry out sub-wire operation.
