WINDING DEVICE
BACKGROUND OF THE INVENTION
1. Field of the Invention
5 The present invention relates to a winding device adapted to
wind, a spun yarn wound around a yarn supplying bobbin as a package.
2. Description of the Related Art
Conventionally, spinningofacompactyarn, which is a spun yarn
10 where the amount of fluff is small, is possible in a spinning device
such as a ring spinning machine and the like. The spinning of the
compact yarn is disclosed in Japanese Unexamined Patent Application
Publication No. 2003-155631. However, there is a problem in which
the fluff increases when rewinding the yarn spun and wound around
15 a yarn supplying bobbin as a package.
This is because a tension applying section and the like adapted
to apply a tension on the spun yarn by making contact with the spun
yarn is provided in a winding device such as an automatic winder or
the like (see Japanese Unexamined Patent Application Publication No.
20 2010-126322) andthe spun yarnmakes contact with the tensionapplying
section and the like at the time of being rewound, causing the fluff
to occur. Since a yarn other than the compact yarn originally has
a certain amount of fluff, the increase in the fluff caused by the
rewinding can be tolerated. However, in a case of the compact yarn
25 of which feature is having a small amount of fluff, if the increase
in the fluff is not suppressed, the feature of the compact yarn would
be lost.
To decrease the fluff having increased by rewinding, there is
known a fluff binding device adapted to decrease the amount of the
30 fluff stickingout of aparent yarnbybinding the fluff with whirling
airflow caused by compressed air or with a roller being in contact
with the yarn. However, electric power for supplying the compressed
air or driving the motor is required to operate the fluff binding
device, which leads to energy consumption. Furthermore, the fluff
:35 binding device is required to be newly provided, thereby causing a
configuration of the winding device to become complicated. Another
problem arises that a tension on the yarn cannot be reduced since
the yarn is required to go through the fluff binding device.
5 SUMMARY OF THE INVENTION
The present invention is made to solve the above-mentioned
problems. The object of the present invention is to provide a winding
device capable of suppressing the amount of the fluff that occurs
when winding the spun yarn wound around the yarn supplying bobbin
10 as the package.
The problems to be solved by the present invention are as
mentioned above, and now, the means for solving such problems will
be described below.
Specifically, a winding device of the present invention is a
15 winding device adapted to wind a spun yarn wound around a yarn
supplying bobbin as a package and includes a yarn supplying section,
a winding section, and a tension applying section. A yarn supplying
bobbin is arrangedinthe yarn supplyingsection. Thewinding section
winds the spun yarn into the package. The tension applying section
20 is arranged in a yarn path between the yarn supplying section and
the winding section and applies a tension on the spun yarn. The
tension applying section includes a plurality of contact members
adapted to apply the tension on the spun yarn by making contact with
the spun yarn and bending the spun yarn. The contact members are
25 arrangedwithanintervalbetweeneachother, andthe intervalbetween
the contact members in a yarn path direction is 5 mm or more.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Next, an automatic winder 100 as a winding device according to
5 an embodiment of the present invention will be described by use of
FIGS. 1 to 5.
In the present embodiment, for convenience of explanation,
directions that are illustrated in the drawings by use of crossing
arrows and indications of front-back, left-right, and upper-lower
10 are defined as a front-back direction, a left-right direction, and
an upper-lower direction. As illustrated in FIG. 2, the automatic
winder 100 is a device for winding (rewinding) as a package P, a yarn
(spun yarn) Y wound around a yarn supplying bobbin B. The automatic
winder 100 is configured of an upright oblong box-shaped main body
15 frame 1 as a base body. The main body frame 1 includes along a yarn
path of the yarn Y stretching from a lower part to an upper part,
eachdevicesuchas a y a r n s u p p l y i n g s e c t i o n l l , anunwindingassisting
device 2, a tension applying section 3, a tension sensor 7, a yarn
joining device 4, a yarn clearer 5 serving as a yarn defect removing
20 device, and a winding section 6.
The yarn supplying bobbin B supplied to the automatic winder
100 is arranged in the yarn supplying section 11. The unwinding
assisting device 2 assists unwinding of the yarn Y from the yarn
supplyingbobbinBby suppressing increase in atension for unwinding
25 that is caused by decrease in the amount of yarn wound around the
yarn supplying bobbin B. The tension applying section 3 applies a
predetermined tension on the yarn Y supplied from the yarn supplying
bobbinB. Adetaileddescriptionwillbemade on the tension applying
section 3 later. The tension sensor 7 is arranged in the yarn path
30 of the yarn Y having passed through the tension applying section 3
and is adapted to output measurement data obtained by measuring the
tension of the yarn Y. The tension sensor 7 may be e.g., a device
adapted to measure the tension of the yarn Y based on force that is
applied to a movable rod by the yarn Y, which is hooked over two fixed
35 rods and the movable rod arranged therebetween.
When the yarn clearer 5 detects a yarn defect, the yarn joining
device 4 cuts the yarn Y for removal of a portion of the yarn defect
and joins a lower yarn from the yarn supplying bobbin B and an upper
yarn from the package P after removing the portion of the yarn defect.
For allowing this, a relay pipe 12 adapted to catch the lower yarn
and to pass the lower yarn to the yarn joining device 4, and a suction
mouth 13 adapted to catch the upper yarn and to pass the upper yarn
to the yarn joining device 4 are mounted on the main body frame 1
both in a state of being capable of swinging. Introduction of the
yarn Y into the tension applying section 3 is carried out in a process
where the relay pipe 12 passes the lower yarn to the yarn joining
device 4, The winding section 6 winds the yarn Y into the package
P. The winding section 6 includes a traverse drum 14 adapted to
displace (traverse) the yarn Y at a predetermined width and a cradle
15 adapted to support a winding tube 9 of the package P.
Next, the tension applying section 3 will be described. As

includes a comb-shaped fixed gate (tension applying body in a fixed
side) 17, a comb-shaped movable gate (tension applying body in a
movable side) 18, a driving mechanism 19, a casing 23, and an
open/close sensor20. Thedrivingmechanism19is configuredcapable
of switching the movable gate 18 to an operating position (position
indicated by a solid line in FIG. 1) and a waiting position (position
indicated by a broken line in FIG. 1). In the operating position,
the movable gate 18 applies the tension on the yarn Y by sandwiching
and bending the yarn Y together with the fixed gate 17; while in the
waiting position, the movable gate 18 separates from the fixed gate
17 andprepares forthe introduction ofthe yarnYbetweenthemovable
gate 18 and the fixed gate 17. A plurality of contact members (41,
44) is arranged in each of the movable gate 18 and the fixed gate
17.
As illustrated in FIG. 1 and FIG. 3, the fixed gate 17 is fixed
on an outer surface of a left wall of the casing 23. The movable gate
18 is swingably supported by a swinging shaft 39 fixed to a bracket
25 in a lower part. The fixed gate 17 is arranged on one side of a
direction D. In a case where a thickness of a plate of the fixed
contact member 41 is T1 as illustrated in FIG. 4, a plate thickness
5 T1 is set to 1 mrn in the present embodiment. The fixed contact member
41 includes in a portion where the fixed contact member 41 makes
I

I
I supported by the swinging shaft 39, four horizontal movable contact
15 members 44 formed in a front part of the boss 43, and a coupling boss
37 arranged in the boss 43 in a projecting manner. In the operating
position, the movable contact members 44 are arranged side by side
with an interval between each other in the yarn path direction D so
as to alternately cross the fixed contact members 41 in the yarn path
20 direction D. In the operating position, the movable contact members
44 and the fixed contact members 41 alternately cross each other in
the yarn path direction D and apply the tension on the yarn Y by
sandwiching and bending the yarn Y. In a case where a thickness of
a plate of the movable contact member 44 is T2 as illustrated in FIG.

contact member 41 in the present embodiment. The movable contact
member 44 includes in a portion where the movable contact member 44
makes contact with the yarn Y, a contact portion 441 with an
arcuate-shaped cross-section . For allowing smooth introduction of
30 the yarn Y, the movable contact member 44 has a front end portion
with an arcuate-shaped cross section . The movable contact member
44 on a side of the fixed contact member 41 is curved in an inwardly
recessed state. Since the movable contact member 44 is curved, when
themovable contactmember 44 and the fixedcontact member 41sandwich
35 the yarn Y in cooperation, a forward movement of the yarn Y is

is transmitted to the movable gate 18 via the second lever 33, the
25 interlocking rod 34, the first lever 32, and the operating rod 35.
When the second solenoid 31 is driven, the movable gate 18 is switched
from the operating position to the waiting position.
Rotating power of the first solenoid 30 is transmitted to the
movable gate 18 via the first lever 32 and the operating rod 35. When
:30 the first solenoid 30 is driven, the movable gate 18 is switched from

t h i s time, the control device 46 switches the movable gate 18 from
the operating position t o the waiting p o s i t i o n by driving the second
25 solenoid 31. When the movable gate 18 reaches the waiting p o s i t i o n
from the switching operation, the reed switch 21 of the open/close

by controlling driving of the first solenoid 30 in accordance with
the measurement result from the tension sensor 7.
With the automatic winder 100 according to the above-described
5 present embodiment, the following effects are provided.
The tension applying section 3 includes a plurality of fixed
contact members 41 and movable contact members 44 both adapted to
apply the tension on the yarn Y by making contact with the yarn Y
and bending the yarn Y. The fixed contact members 41 and the movable
10 contact members 44 are arranged with an interval between each other,
and the interval L between the fixed member 41 and the movable member
44 in the yarn path direction D is set to 5 mm or more. This allows
suppression of the amount of fluff that occurs when winding the yarn
Y wound around the yarn supplying bobbin B as the package P.
15 The interval Lbetweenthe fixedmember 41andthemovablemember
44 in the yarn path direction D is set to 20 mm or less. This allows,
without causing the tension applying section 3 to be large,
suppression of the amount of fluff that occurs when winding the yarn
Y wound around the yarn supplying bobbin B as the package P.
20 The fixed contact member 41 and the movable contact member 44
are set such that the ratio of the thickness TI, T2 in the yarn path
direction D with respect to the interval L between the fixed contact
member 41andthemovable contact member 44 in the yarn path direction
D is 1 : 10 or more. By determining the interval L between the fixed
25 contact member 41 and the movable contact member 44 so as to realize
such a ratio, it is possible to suppress the amount of fluff that
occurs when winding the yarn Y wound around the yarn supplying bobbin
B as the package P.
The fixed contact member 41 and the movable contact member 44
30 are set such that the ratio of the thickness TI, T2 in the yarn path
direction D with respect to the interval L between the fixed contact
member 41andthemovable contact member 44 in the yarn path direction
D is 1:20 or less. By determining the interval L between the fixed
contact member 41 and the movable contact member 44 so as to realize
35 such a ratio, it is possible to suppress the amount of the fluff that
@ occurs when winding the yarn Y wound around the yarn supplying bobbin
B as the package P.
The fixedcontactmember 41includes the arcuate-shapedcontact
portion 4 1 1 b e i n g i n c o n t a c t w i t h t h e y a r n Y ; while themovable contact
5 member 44 includes the arcuate-shaped contact portion 441 being in
contact with the yarn Y. Accordingly, even when the force from the
fixed contact member 41 and the movable contact member 44 is applied
on the yarn Y, the yarn Y is less likely to be damaged by the fixed
contact member 41 and the movable contact member 44, thereby allowing
10 suppression of the fluff occurrence.
Providedare the fixed gate 17 inwhich the fixed contact member
41 is arranged and the movable gate 18 in which the movable contact
member 44 is arranged, and the fixed gate 17 and the movable gate
18 a r e a l t e r n a t e l y a r r a n g e d i n t h e y a r n p a t h d i r e c t i o n D . The interval
16 L between the fixed contact member 41 and the movable contact member
44 in the yarn path direction D is the interval L in the yarn path
direction D between the contact portion 441 of the movable gate 18
in the operating position and the contact portion 411 of the fixed
gate 17 adjacent thereto. By determining the interval L between the
20 contact portion 411 and the contact portion 441 in such a manner,
it is possible to suppress the amount of the fluff that occurs when
winding the yarn Y wound around the yarn supplying bobbin B as the
package P.
The interval L between the contact portion 411 and the contact
25 portion 441 in the yarn path direction D is the interval L in the
yarn path direction D between the center of the thickness of the
contact portion 441 of the movable gate 18 and the center of the
thickness of the contact portion 411 of the fixed gate 17. By
determining the interval L between the contact portion 411 and the
30 contact portion 441 in the yarn path direction D in such a manner,
it is possible to suppress the amount of the fluff that occurs when
winding the yarn Y wound around the yarn supplying bobbin B as the
package P. Thus, when rewinding the yarn spun by a ring spinning
machine or the like by a winding device such as the automatic winder
35 or the like, it is possible to suppress the fluff occurrence, thereby
allowing maintenance of the yarn quality from the time of spinning.
The fixed gate 17 includes five fixed contact members 41; while
the movable gate 18 includes four movable contact members 44. This
allowssuppressionofthefluffoccurrencewhileapplyingtherequired
tension.
Although the embodiments of the present invention have been
described, thepresent invention is not limitedtothe above-described
embodiments, and various changes may be made.
According to the winding device of the present invention, the
interval between the contact members in the yarn path direction is
20 mm or less.
According to the winding device of the present invention, a
ratio of a thickness of the contact member in the yarn path direction
with respect to the interval between the contact members in the yarn
path direction is 1:10 or more.
According to the winding device of the present invention, the
ratioofthe thickness ofthe contactmember inthe yarnpathdirection
with respect to the interval between the contact members in the yarn
path direction is 1:20 or less.
According to the winding device of the present invention, the
contact member includes an arcuate-shaped contact portion that makes
contact with the spun yarn.
The winding device of the present invention includes a fixed
gate and a movable gate in which the contact members are arranged.
The movable gate and the fixed gate are alternately arranged in the
yarn path direction. The interval between the contact members in the
yarn path direction is an interval in the yarn path direction between
the contact portion of the movable gate in an operating position and
the contact portion of the fixed gate adjacent thereto.
According to the winding device of the present invention, the
interval between the contact portions in the yarn path direction is
an interval in the yarn path direction between a center of the
thickness of the contact portion of the movable gate and a center
in a thickness of the contact portion of the fixed gate.
According to the winding device of the present invention, the
fixedgate includes five contact members and themovable gate includes
four contact members.
The present invention provides the following effects.
According to the winding device of the present invention, the
tension applying section includes the plurality of contact members
adapted to apply the tension on the spun yarn by making contact with
the spun yarn and bending the spun yarn. The contact members are
arranged with the interval between each other, and the interval
between the contact members in the yarn path direction is 5 mm or
more. This allows suppression of the amount of the fluff that occurs
when winding as the package, the spun yarn wound around the yarn
supplying bobbin.
A consideration can be made as a reason for allowing, in the '
above-described manner, suppression of the amount of the fluff that
occurs. That is, when the yarn travels between the contact members,
the tension is applied on the spun yarn by force from the contact
members. In a case where the interval between the contact members
is less than 5 mm and the contact members are densely arranged, a
free length of the spun yarn (a length of a portion of the spun yarn
laid across an adjacent contact member) is short, and elasticity of
the spun yarn decreases (a tension of the spun yarn increases) . When
the force from the contact members is applied on the spun yarn under
this state, the spun yarn is likely to be damaged, thereby easily
causing the fluff. On the other hand, in a case where the interval
between the contact members is 5 mm or more and the contact members
are not densely arranged, the free length of the spun yarn is long
and the elasticity of the spun yarn increases (the tension of the
spun yarn decreases) . Even when the force from the contact members
is applied on the spun yarn under this state, the spun yarn is less
likely to be damaged since the spun yarn absorbs the force by
stretching, thereby allowing suppression of the fluff occurrence.
According to the winding device of the present invention, the
interval between the contact members in the yarn path direction is
20 mm or less. This allows suppression of the amount of the fluff . .
thatoccurswhenwindingthe spun yarnwoundaround the yarn supplying
bobbin as the package without causing the tension applying section
to be large.
According to the winding device of the present invention, the
contact members are set such that the ratio of the thickness in the
yarn path direction with respect to the interval between the contact
members in the yarn path direction is 1: 10 or more. By determining
the interval between the contact members so as to realize such a ratio,
it is possible to suppress the amount of the fluff that occurs when
winding the spun yarn wound around the yarn supplying bobbin as the
package.
According to the winding device of the present invention, the
contact members are set such that the ratio of the thickness in the
yarn path direction with respect to the interval between the contact
members in the yarn path direction is 1:20 or less. By determining
the intervalbetweenthe contactmembers so as to realize sucha ratio,
it is possible to suppress the amount of the fluff that occurs when
winding the spun yarn wound around the yarn supplying bobbin as a
package.
According to the winding device of the present invention, the
contact member includes the arcuate-shapedcontactportionthatmakes
contact with the spun yarn. This allows suppression of the fluff
occurrence since the spun yarn is less likely to be damaged even when
the force from the contact members is applied on the spun yarn.
According to the winding device of the present invention, the
fixed gate and the movable gate each having the contact members are
provided, and the movable gate and the fixed gate are alternately
arrangedinthe yarnpathdirection. The intervalbetween the contact
members in the yarn path direction is the interval in the yarn path
direction between the contact portion of the movable gate in the
operating position and the contact portion of the fixed gate adjacent
thereto. By determining the interval between the contact members in
such a manner, it is possible to suppress the amount of the fluff
that occurs when winding as the package, the spun yarn wound around
the yarn supplying bobbin.
According to the winding device of the present invention, the
@ interval between the contact members in the yarn path direction is
the interval in the yarn path direction between the center of the
thickness of the movable gate and the center of the thickness of the
fixed gate. By determiningthe interval between the contact members
