tnoutli 73. When yarn breakage or yarn cutting COI- removing the yarn defect occurs in a
certain spinning unit 2, the yarn splicer carriage 3 runs on a rail 74 to that spinning unit 2 and
stops there (see FIG I ) . Tlie suction pipe 72 sucks and captures an end of the yarn sent out
fiotn the spinning device 20 while rotating about the shaft to move in an upper-lo~ver
direction, aid guides the yarn to the splicer 71. Tile suction ~iiouth7 3 sucks and ca1)tures an
end of tlie yarn fio~nth e package P supported by the winding device 40 while rotating about
the shaft to move in an upper-lower dil-ection, and guides the yam to the sl~licer 71. 'Tlle
splicer 71 splices the ends of tlie guided yarns.
100391 The winding device 40 includes a cradle ~ I - I I I4 2 supported swingably about a
supporting shaft 41, The cradle arm 42 rotatably sul~l)ortsa bobbin B for winding the yarn Y.

thus makes the yarn traverse in a width direction of the package P The winding device 40
rnakes the package P in contact with the winder druni 43 rotate, and thus \vi~ids the yarn Y
into the package P while traversing the yarnY with the traverse device 44.
[0040] A dust collector 80 will be described with reference to FIG 2 and FIG 3. The
dust collector 80 includes an integration duct 85 and an integration blower 86. In the dust
collector 80 oS this embodirr~ent, one integl.atior1 duct 85 aud one integration blower 86 are
provided for one spinning machine I including the plurality of spinning units 2. Tlie cotlon
flies and the air eshausted froni sucking and separating devices 90 to be described later are
collected in the integration duct 85 in an integrated manner. The integration blower 86 sucks
the cotton flies and the air passing through the integration duct 85, and produces airflo\v in tlie
integration ducl85.
[0041] The dust collector 80 includes unit ducts 81, flexible ducts 82, shutters 83 as shutter
members, aid the sucking and separating devices 90. In the dust collector 80, one unit duct
81 is provided for each group d four spinning units 2. The unit duct 81 is coupled to the
integration duct 85 tl~roughth e sucking and separating device 90. A plurality of the flesible
ducts 82 are coupled to the unit duct 81. In the unit duct XI, cotton flies and air exhausted
rrom Lhe flesible ducts 82 are collected in an integrated manner.
[0042] The flexible duct 82 is disposed near the drafting device 10 and tlie spinning
device 20 oS the spinning unit 2. Flexible ducts 82A. 82B, 82C, and 82D lia\te tlieir opening
sides disposed around the drafting device 10 aid the spinning device 20 and thus suck the
cotton flies G-0111 the dra.fling device 10 aid the spinning devices 20 (see FIG 2). The
flexible duct 82A has its opening side disposed near tlie draft cradle 16 of tlie drafting device
10. The flexible ducts 82B and 82C have their opening sides disposed near the respective
bottom roller sides of the drarting devicc 10. The flexible tluct X2D is disposed above ;~nd
near the sl~inning device 20.
[0043] The shutter 83 is disposed between each sucking and separating device 90 and the
integration duct 85. The shutter 83 is disposed in an openable and closable manner so as to
be able to block airflow between the sucking and separating device 90 aid tlie integration
duct 85. If the airflow betwee11 the sucking and separating device 90 and the integration
duct 85 is not to be blocked, the shutter 83 map be omitted.
[0044] The sucking and separating device 90 will be described with reference to FIG 4.
FIG 4A is a front view of tlie sucking and separating device 90 and FIG 4B is a side
vie\v of the suckitig atid separating device 90. For the better understanding of the
description, a side on wliich an inrake duct 93 of the sucking atid separating device 90 to be
described later in FIG 4 is disposed is defined as a front side of the suckilig and separating
device 90.
[0045] The sucking and separating device 90 includes a case 95 as a casing and a plate
fan 100 as a suction flow generating device. The case 95 is formed to have a cylindrical
shape. The plate fan 100 is arranged in tlie case 95.
[0046] The case 95 includes a first exhaust duct 91 as a first exhaust portion, a second
exhaust port 92 as a second exhaust portion, the intake duct 93 as a11 intake portion, a net 96
as an air permeable member, and a cover 94 as a switclii~ig tnember. When the cylilidrical
case 95 is viewed from tlie front as a circle, the first exhaust duct 91 extends in a tangential
direction of the circle, on the side \\!all of the cylindel-. The second exhaust port 92 is formed
on the side surface of the case 95 opposite to tlie side on which the first exha~~dsutc t 91 is
formed. The intake duct 93 extalds to penetrate the center of tlie cylindrical case 05.
[0047] The net 96 is disposed to co\ler the second exhaust port 92. The net 96 is
provided for removing tlie cotton fly of the cotton fly and the air sucked by tlie plate fan 100,
and clischwging a part of the air Ili~.ougli the secorld exhaust port 92. Tlie cotton flies
separated by the net 96 accumulate on the inner surface side of tlie net 96, and by the airflo\\~
produced by the plate fa1 100, move along the inner peripheral surface of tlie case 95 in a
sliding or tr~~nblim~lagn ner to be exhausted through the Tirst exhaust duct 91
[0048] The cover 94 is slidable along the sidc surface of the cylindrical case 95 \vIiile
partially covering the outer side olthe second exhaust port 92. The sliding oCthe cover 94 is
achieved manually or through a driving device. Tlie size of the cover 94 may be tlie sane as
that of the second exhaust port 92 so that the second exhaust po~t 92 call be closed or opened.
[0049] The plate fan I00 produces the suction flow for sucking the cotton flies produced
in the plurality of spinning units 2. The plate Cat1 100 includes plates 101 as blade members.
a shalt 102, and an electric motor 105 as a driving device. The plates 101 have a flat plate
shape and radially stand on the shaft 102. All the plates 101 are disposed on the inner side
oC the case 95 while being apxt fi-om the net 96 by a predetermined distance D and radially
standing on the shaft 102. The predetermined distance D is of a suficient length for the
plates 101 to contact and scrape out the cotion flies when the cotton flies are accumulated on
the inner side surface of the net 96. Alternatively, the predetermined distance D is of a
suricient length for the accumulated cotton flies to be separated from tlie net 96 by the
airflow produced by the plates 101, even if the plates 101 do not contact tlie cotton flies.
The electric motor 105 is disposed on tlie side oftlie cylindrical case 95 opposite to the side
on which the intake duct 93 is disposed, and drivingly rotates the sliafi 102.
[0050] The net 96 will be described Inore in detail with reference to FIG 5. First. tlie
plate Can 100 rotates in the case 95 so that the airflow Crotn the intake duct 93 to the first
exhaust duct 91 is produced in the case 95. In particulal; on a side surface of the case 95
opposite to the side where the first esha~~dsut ct 91 is formed, the airflo~va long tlie side
surface ofthe case 95 is produced. The net 96 is disposed on the side surface on the side oT
the case 95 o])])ositc to tlic side wlicre thc first exhaust duct 91 is formcd. Since the nct 96 is
disposed at that position, the airflo~vin the radial direction of the case 95, that is, the airflow
passing through tlie net 96 is produced.
[0051] I-Iere, an average flow velocity of the airflo~vo n the inner surface side of the net
96 is defined as an average flow velocity V The average flow ~lelocity V is brolien down
into two velocity components: an average flolv velocity VI of air flowing along the net Oh
(does not pass tl~rouglitl re net 96); and an average flo\v velocity V2 of air passing through tlie
net 96. The net 96 is designed in sucli a manner that the average flow r~elocity VI becomes
four times as high as the average flow~ velocity V2 or lliglier Specifically, tlie tliickness of
tlie net 96, tlie size of the net 96, the mesh (representing the mesh size, that is, the number or
meshes per square inch) of tlie net 96, and the like are set in such manner that the average
flow velocity V1 becomes four times as high as the average flow velocity V2 or higher.
[0052] The net 96 is designed as described above for the following reasons. Specificall!:
a higher average flow velocity V2 of the air passing throilgli the net 96 relative to the average
flow velocity V1 ofthe air moving along the net 96 is directly related to a higher cotton fly
removing perfomlance oftlie net 96. Moreover, an amount of air exliausted from the second
exhaust porl92 increases, and thus ai ailount of air exhausted lo tlie integration duct 85 from
the first exhaust duct 91 can be reduced. Hoive~~ear, higher average flow ~lelocityV 2
imposes a problem that the cotton flies easily accumulate on the inner side surface of the net
6 On the other hand, a smaller average flo\v ~~elocitVp2 relative to the average flow
velocity V1 makes the cotton flies less likely to accu~nulate on the inner side surface of tlie
net 96, but is directly related to a lower cotton fly removing performance or the net 06.
Moreover, an amount of air exhausted Crom the second exhaust port 92 is reduced, and an
amount of air exhausted to the integration duct 85 from the first exhaust duct 91 is reduced.
[0053] As described above, the relationship between the average flow velocity V1 of the
air moving along the net 96 and the average flow velocity V2 of the air passing througli the
net 96 largely aKects the cotton fly removing performa~ce ill the suclti~ig atid separating
device 90, and the an~ount of air exhai~sted from the suclting and separating device 90 to the
integratio~l duct 85. For balancing the conoll fly rcmoving pcrformmice in the suclti~ig and
separating device 90 and the aniount of air exl~a~~sftreodm the sucking and separating device
90 to the integratio~i duct 85, the amount of air exhausted from the firs(. axhaust. tluct. !)I to the
integration duct 85 is preferably 25% to 50% ofthe amount of air sucked by the sucking and
separating device 90 horn the intalte duct 93. To achieve llle above-describeti ratio between
the amou~it of air exhausted from tlie sucking and separating device 90 to the integration duct
85 and the amount of air sucked by {lie sucking and sepal-ating device 90, the net Oh is
preferably designed in such a mailier that the average floiv \#elocit)V~ 1 becomes Tour times as
high as the average flow velocity V2 or higher.
100541 The operatio11 and the effect of the embodiment are described belov!
The operation of the sucking and separating device 90 is described with reference to FIG
6.
I11 tlie sucking atid separating device 90, by the rotation of the plate fan 100, tlie outward
airflow from the center is produced by the ce~itrifugal force on the do\vnstrea~n side in tlie
I-otational direction of the plate fan 100 in the case 95. The centrifugal force lnalies the air
and the cotton flies that entered the sucking and separating device 90 fiom tlie intake duct 93
flow toward the first outlet duct 91 along the inner side surface of the cylindrical case 95.
[0055] The net 96 covers the second exhaust port 92. Thusl in the second exhaust port
92, of the air and the cotto11 flies that are made to flow outtvard by the centrifugal force, the
cotton flies accu~nulate on the innel- side of the net 96, and only tlie air is exhausted out
through the net 96. When the cotton flies accumulate on the inner side of {lie net 96 for a
certain amount, the air flowing along tlie net 96 discharges the cotton flies toward the first
eshaust duct 91. The second exhaust port 92 never sucks the air fiom the esternal, because
tlie out~vard airflow from the center is produced by tlie centrifugal force in tlie case 95.
[0056] When the cotton flies further accunlulate on the inner side of the net 96, for
example, up to the accumulated mount reaching or exceeding the height D_ the couoti flies
are scral~ed out by the plates 101 of tlie plate fm 100. The air flowi~lg alo~ig the net 96
eshausts the scraped cotton flies toward the first exhaust duct 91
100571 When tlie cover 94 slides to ~~nrtiallcyo ver the second exhaust port 92 (see 1:IC;. 4),
a smaller amount of air passes through the second eshaust port 92 covered by the net 96, ru~d
tlie a~nount of air that flows along tlie net 06 relatively increases. Thus. sepxalion of the
conon flies accumulated on the net 96 is facilitated.
[0058] Since tlie net 96 is designed in such a manner that the average flow velocity V1
becomes four times as high as the average flo~vv elocity V2 or higller, tlie ;imount of air Ilia1
flows into the integration duct 85 is 25%) to 50% of tlie amount or air s u c l d by tlie sucliing
and separating device 90, that is, the air that passes through the intake duct 93.
100591 The eirect ofthe sucking and separating device 90 will be described.
The sucking aid separating device 90 cal suck the cottoll flies in the suction flow
including the air and the cotton flies, while discharging only the air to the external through tlie
second exhaust port 92. Thus, the sucking and separating device 90 can surely separate tlie
cotton flies aid the air. The sucking and separating device 90 exhausts a pal of the air in the
suctio~if low including the air and the cotloll flies to the external through the seco~lde xlia~~st
port 92. Thus, the a~nounto f air exhausted to the integ~ationd uct 85 cai be made small, and
thus tlie increase in size ofthe integration duct 85 can be prevented.
[0060] Eve11 when the conon flies are acculnulated on the inner side ofthe side surSace oS
the case 95, the cotton flies can be scraped out by the plates 101.
[OOGl] The net 96 is designed in such a maliner that the average flo\v velocity V1 of the
air lnovi~iga long the net 96 becomes four times as high as tlie average flow velocity V2 oftlie
air passing tlirough the net 96 or liiglier. Tlius, the cotton flies can be collected fiom tlie
spinning unit 2 while tlie unnecessary air is exhausted through the net 96 in the sucking and
separating device 90.
[0062] The cottoll flies accumulated on the net 96 in a portion covered by the cover 94 is
separated from the net 96, 'and can be exhausted to the ir~tegrationd uct 85. Even when the
cottoll flies accutnulate on the net 96, tlie textile machine 1 cai be continuously operated
while the cotlo~lfl ies are removed.
100631 An etTect of the dust collector 80 will be described.
In the dust collector 80, the sucking and separating device 90 produces the airflow from
the spinning unit 2 to the integration duct 85. Thus, the cotton flies collected [rom the
spinning units 2 can be surely exhausted to tlie integration duct 85.
[0064] In tlie dust collector 80, tlie shutters 83 block the ail.flow bet\veen the sucking atid
separating devices 90 aid the integration duct 85. Tlius, the sucking and separating devices
90 can be removed easily. Accordingly. the sucking and separating devices 90 cal be easily
maintained. I-Iere, only the srrcking and separating device 90 to be mai~rtained can be
removed from tlie textile machine I , while the rest of the sucking and separilting devices 90
continue their operation. Thus, the winding operation for the pacltage P can be continued in
tlie spinning units 2 coupled to the sucking and separating devices 90 continuing their
operation. Thus, the productivity can be improved in the textile machine 1 as a wliole.
I00651 In the dust collector 80, one unit duct 81 is provided Sor each group o f four
spinning units 2. Thus, the integration duct 85 and the integration blower 86 can have
smaller configurations, aid the power consumption of the textile machine 1 as a whole can be
reduced.
100661 In the embodiment, tlie air permeable member is tlie net 96. However, the
configuration is not limited to this. For example, the air pesmeable member may be a
nonwoven fabric that covers the second exhaust port 92. Thus, materials other than the net
and the nonwoven fabric that can separate the air and the cotton flies and transmit air without
transmitting tlie cotion flies may be used as the air transmitting member
[0067] In the enibodiment, tlie second exhaust port 92 is formed on a side surface of tlie
case 95. Hovvever, tlie configuration is not limited to this. The second exlia~~psotr t 92 may
be formed at any intel-mediate pollion of the airflow from tlie suctio~i duct 93 to the first
exhaust duct 91 produced by the plate fan 100. For example, the second exhaust port 92 can
be formed on the front surface or tlie rear surface oC the case 95. I f the second exhaust port
92 is formed on the front surface or the real- surface of the case 95, all the plates 101 are apart
from inner sides of the k"ront surface and tlie rear surface of tlie case 95 by the predetermined
distance D.
100681 In the embodiment, the suclion Ilo\v generating tlevice is tlie plate fan 100.
However, tlie configuration is not limited to tliis. For example, the suctioti flow generating
device may be a turbo fan Altemati\lely, the suctio~l flow genelxtiting device may he other
rotating bodies.
100691 In tlie embodiment, the case 95 is configured to have a cylindrical slial~e. The
slial~e is not li~nited to this and any slial~e call be eml~loyed as long as an internal wall surface
conforms to the air floiv produced by tlie plate fan 100.
100701 In the embodiment, the cover 94 is configured lo be slidable along the side surface
of the cylindrical case 95. However, the configuration is not limited to this. I f a large
amount of cotton flies never accu~iiulate on the net 96, the cover 94 may be omitted.
[0071] In tlie embodiment, one unit duct 81 is provided for each group of four spinning
units 2. I-Iowever, the configuration is not limited to this. For example, one unit duct 8 1
may be provided for one spinning unit 2, or for a group of two, three, or five or more spinning
units 2.
100721 In the embodiment, the spinning machine illcludes air-operated spinning units.
Hoive\fer, the configuration is not limited to this. For esa~nl)let,h e present invention can be
applied lo any textile machines including an automatic winder, a yarn twisting machine, a
doubler, and the like where the yarns are rubbed on each other and thus the cotton flies are
produced.
[0073] An auto~naticw inder generally includes a yarn feeding portion, a tension applying
device: a pan defect detector (clearer), a yarn splicer, and a \vinder. The automatic winder
winds the yarns unraveled from the yarn feeding bobbin around a winding bobbin \\~hile
traversing the yams, and thus fortns a package having a predetermined length and a
predetermined shape.
[00741 The yarn feeding portion includes a holding portion that holds the yarn feeding
bobbin and an unwinding assistance device. The unwinding assistatlce device moves a
regulation tne~nberc overing a core tube in conjunction with the unwinding ofthe yarns iirom
the yarn feeding bobbin, and thus assists the unwinding of the yarns l?om the yarn feeding
bobbin. 'She regulation member conies into contact with a balloon formed above the yarn
feeding bobbin as the yarns unraveled from the yarn feeding bobbin are swung and applies an
approl~riatete nsion to the balloon, and thus assists the unwinding ofthe yarns.
100751 A hiown gate telisioner or disk tensioner cal be used as the tension al~~lying
device. The tension applying device applies a predetermined tension to the yarns to be
wound into a pacliage. The yarn defect detector detects \uliether there is a yarn defect before
the yarns Fro111 the yarn feeding bobbin are ~vound into the package in the winder. When tlic
yarn tlefecl is detected by the yarn defect detector, the automatic winder cuts the yarns and
removes the yarn defect, the yarn splicer splices the yams, and the winder resumes the
winding.
[0076] In such an automatic winder, a suction mouth of the flexible duct 82 of the
sucking and separatitig device 90 map be disposed near the tension applying device; so that
tlie sucking and separating device 90 sucl;s and separates the cotton flies and the like
produced in the tension applying device. Alternatively, the suction mouth of the flesible
duct 82 of the sucking arid separating device 90 may be disposed near the yarn feeding
portion so that tlie sucking and separating device 90 sucks atid separates the cottoll flies aid
the like produced in the yarn feeding portion.
