YARN WINDING DEVICE
BACKGROUND OF THE INVENTION
1. Field of the Invention
- 5 The present invention relates to a yarn winding device adapted
to wind a yarn to form a package.
2. Description of the Related Art
Japanese Unexamined Patent Publication No. 2004-352465
10 discloses an automatic winder including a plurality of winding units
adapted to wind a yarn to form a package. One winding unit winds the
yarn unwound from a yarn supplying bobbin around a bobbin supported
by a cradle while traversing the yarn by a traverse drum to form a
package. A clearer and a yarn joining device are arranged between
15 the yarn supplyingbobbin and the traverse drum. The clearer detects
a yarn defect contained in a travelling yarn, and the yarn is cut
by a cutter arranged in the clearer when the yarn defect is detected.
The yarn joining device joins the yarn from the yarn supplying bobbin
and the yarn from the package at the time of yarn breakage or at the
20 time of yarn cut by the cutter.
In each winding unit, when the yarn defect is detected by the
clearer and the yarn is cut by the cutter, a setting condition of
such yarn cut can be displayed on a display section of each winding
unit to check whether the yarn is cut according to the setting
25 condition.
The clearer detects the yarn defect, and at the same time,
acquires various types of information associated with the state of
the yarn such as thickness and hairiness of the travelling yarn. If
such information can be appropriately checked by an operator, this
30 is advantageous in checking the details (thickness, length, or the
like) of the actually removed yarn defect, adjusting each section
of the winding unit to form a package of better quality, and the like.
However, in Japanese Unexamined Patent Publication No. 2004-352465,
the setting condition of when the yarn is cut with the cutter is merely
35 displayed on the display section of the winding unit, and the useful
information associated with the state of the yarn detected by the
clearer cannot be easily checked by the operator.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Adescription will bemade below on an embodiment ofthe present
invention. The present embodiment is an example in which the present
invention is applied to an automatic winder including a plurality
35 of winding units adapted to wind a yarn unwound from a yarn supplying
bobbin around a winding tube to form a package. F I G . 1 is a front
view of the automatic winder according to the present embodiment,
and F I G . 2 is a front view of one winding unit ofthe automatic winder.
As illustrated in F I G . 1, an automatic winder 1 (yarn winding
device) includes a plurality of winding units 2 arranged in a line
in a left and right direction of F I G . 1, a doffing device 3 arranged
to freely travel in the direction in which the plurality of winding
units 2 arearranged, andamachine control device 4 adaptedtoperform
an overall control of the automatic winder 1. The machine control
device 4 is arranged at one end side in the direction in which the
winding units 2 are arranged.
The automatic winder 1 is configured to send a command to each
of the plurality of winding units 2 from the machine control device
4, and wind a yarn Y unwound from a yarn supplying bobbin B around
the winding tube to form a package P in each winding unit 2. When
a fully-wound package is formed in a certain winding unit 2, the
doffing device 3 moves to above the relevant winding unit 2 to replace
the fully-wound package with an empty winding tube 17 (see F I G . 2).
The machine control device 4 controls the operation of each winding
unit 2, and also performs monitoring of the operation state, setting
and storing of the operation parameters, and the like.
Next, a description will be made on a detailed configuration
ofeachwindingunit2. Thewinding unit2 illustratedin F I G . 2 winds
the spun yarn Y unwound from the yarn supplying bobbin B around the
winding tube 17 while traversing to form the package P of a
predetermined shape.
The winding unit 2 includes a unit machine 10, a yarn supplying
sectionlladaptedto unwindand supply the yarn~oftheya rn supplying
bobbin B, a yarn processing executing section 12 adapted to perform
various types of processing on the yarn Y supplied from the yarn
supplying section 11, and a winding section 13 adapted to wind the
yarn Y processed by the yarn processing executing section 12 around
thewinding tube 17to formthe package P. The yarn supplying section
11, the yarn processing executing section 12, and the winding section
13 are arranged in a line from top to bottom in this order. The unit
machine 10 includes an operation panel 25 and a unit control section
26 (see F I G . 4).
The yarn supplying section 11 includes a peg 15 for holding the
yarn supplying bobbin B, and an unwinding assisting device 16 for
assisting the unwinding of the yarn Y from the yarn supplying bobbin
B. At the time of the unwinding of the yarn Y (at the time of yarn
winding), the peg 15 is in a perpendicular state illustrated in F I G .
2. The peg 15 is driven by a peg driving section 28 (see F I G . 4) to
tilt forward and backward (perpendicular direction in the plane of
drawing in F I G . 2 ) , to thereby discharge the empty yarn supplying
bobbin B and receive a new yarn supplying bobbin B from a magazine
(not illustrated). Theunwindingassistingdevice 16includes atube
body that is driven up and down by an unwinding assisting device
driving section 29 at an upper part of the yarn supplying bobbin B.
This tube body is lowered according to the progress of the unwinding
of the yarn Y from the yarn supplying bobbin B to regulate expansion
(balloon) of the yarn Y during the unwinding, and stabilize the
unwinding of the yarn Y.
The winding section 13 includes a cradle (not illustrated)
adapted to grip the winding tube 17 in a freely rotating manner, and
a traverse drum 18 rotatably driven by a drum driving section 27.
A spiral traverse groove 18a is formed on a peripheral surface of
the traverse drum 18, and the traverse groove 18a traverses the yarn
Y. The traverse drum 18 is rotatably driven in a state of making
contact with the package P formed around the winding tube 17 while
traversing the yarn Y with the traverse groove 18a. Consequently,
the package P rotates by contacting friction with the traverse drum
18, and the yarn Y unwound from the yarn supplying bobbin B is wound
around the winding tube 17.
The yarnprocessing executing section12 includes a yarn filler
19, a tension applying device 20, a yarn joining device 21 (yarn
joining section), and a yarn clearer 22 (yarn state detecting
section).
The yarn filler 19 detects presence or absence of the yarn Y
between the unwinding assisting device 16 and the tension applying
device 20. The tension applying device 20 applies a prescribed
I tension on the travelling yarn Y. F I G . 2 illustrates, by way of
I ~ example, a gate-type tension applying device including fixed comb
I teeth 20a and movable comb teeth 20b driven by a ~ tension applying
i - 5 device driving section 30 (see F I G . 4).
The yarn joining device 21 joins a lower yarn Y1 from the yarn i
supplying bobbin B and an upper yarn Y2 from the package P at the
time of the yarn cut by a cutter 22a when the yarn defect is detected
by the yarn clearer 22, to be described later, at the time of yarn
10 breakage during the winding, or at the time of replacing the yarn
supplying bobbin B. An example of the yarn joining device 21 is an
air splicer that performs yarn joining operation by generating an
airflow to cause fibers of the lower yarn Y1 and the upper yarn Y2
to entangle with one another.
15 A lower yarn catching-and-guiding member 23 adapted to catch
the lower yarn Y1 from the yarn supplying bobbin B and guide the lower
yarn Y1 to the yarn joining device 21, and an upper yarn
catching-and-guiding member 24 adapted to catch the upper yarn Y2
from the package P and guide the upper yarn Y2 to the yarn joining
20 device 21 are respectively arranged below and above the yarn joining
device 21. The lower yarn catching-and-guiding member 23 and the
upper yarn catching-and-guidingmember 24 bothhave one end rotatably
attached to the unit machine 10. Furthermore, the lower yarn
catching-and-guiding member 23 and the upper yarn
25 catching-and-guidingmember24 canbe swungupanddownbybeingdriven
I by a lower yarn guiding member driving section 31 and an upper yarn
guiding member driving section 32 (both illustrated in F I G . 4).
Asuctionport23aoftheloweryarncatching-and-guidingmember
23 sucks and catches the yarn end of the lower yarn Y1, and is swung
30 upward frombelowto guide the lower yarnY1tothe yarn joining device
21. At the same time, the upper yarn catching-and-guiding member 24
has a suction mouth 24a swung to a yarn end catching position in
proximity to a contact point of the package P and the traverse drum
18. The suction mouth 24a sucks and catches the yarn end of the upper
35 yarn Y2 from the package P at the yarn end catching position, and
is again swung downward. The upper yarn catching-and-guidingmember
24 then guides the upper yarn Y2 to the yarn joining device 21. The
yarn joining device 21 joins the yarn end of the lower yarn Y1 guided
by the lower yarn catching-and-guiding member 23 and the yarn end
of the upper yarn Y2 guided by the upper yarn catching-and-guiding
member 24 to obtain one yarn Y. Accordingly, the winding of the yarn
Y by the winding section 13 can be resumed.
The yarn clearer 22 constantly acquires information on a
thickness of the travelling yarn Y, and based on this information,
detects an abnormal portion in the yarn Y where the yarn thickness
is thick by a prescribed amount or more as a yarn defect. In addition
to the information of the yarn thickness, the yarn clearer 22 also
acquires information associated with the hairiness of the travelling
yarn Y. As information associated with the state of the travelling
yarn Y, the yarn clearer 22 transmits to the unit control section
26 the information associated with the thickness of the yarn Y, the
information associated with the hairiness, and the information
associated with the detected yarn defect. The yarn clearer 22
includes the cutter 22a (yarn cutting section), which immediately
cuts the yarn Y when the yarn defect is detected by the yarn clearer
22.
If the yarn Y is cut after the yarn defect is detected by the
yarn clearer 22, the yarn defect remains in the upper yarn Y2. In
the yarn joining device 21, the lower yarn Y1 and the upper yarn Y2
are joined after the remaining yarn defect is removed from the upper
yarn Y2.
Next, adescriptionwillbemade ontheoperationpanel25. F I G .
3 is a front view of the operation panel 25. As illustrated in F I G .
2 and F I G . 3, the operation panel 25 includes a display section 40,
an operation button group 41, an operation switch 42, and two alarm
lamps 43, 44.
The display section 40 is installed at the upper part of the
operation panel 25. The display section 40 includes three 7-segment
LEDs 40a arranged side by side. Each of the three 7-segment LEDs 40a
has a decimal display function. Accordingly, the display section 40
can display three characters, numbers, or symbols at the same time.
Thedisplay section 40 displaysinformationassociatedwiththe
winding unit 2. For example, a unit number is individually set to
each of the plurality of winding units 2 of the automatic winder 1.
The display section 40 of each winding unit 2 can display the unit
number ofthe relevant winding unit 2. When performingthe operation
adjustment of each section of the winding unit 2 described above,
the set value can be displayed. The operation adjustment includes,
for example, an angle adjustment of the peg 15, a height adjustment
of the tube body of the unwinding assisting device 16, a position
a d j u s t m e n t o f t h e m o v a b l e c o m b t e e t h 2 0 b o f t h e t e n s i o n a p p l y i n g d e v i c e
20, or the like. Furthermore, in the present embodiment, in
particular, the display section 40 can also display information
associated with the state of the yarn Y detected by the yarn clearer
22. The display of the information detected by the yarn clearer 22
will be described in detail later. The number of 7-segment LEDs
constituting the display section 40 is not particularly required to
be three, and can be appropriately changed according to the
information to be displayed.
The operation button group 41 is installed at a central part
in the vertical direction of the operation panel 25. The operation
button group 41 is configured by a total of five buttons 41a to 41e
at the top, bottom, left, right, and middle. The five buttons 41a
to 41e of the operation button group 41 are operated by the operator
when switchingthe display content ofthedisplay section 40, changing
the set value at the time of adjustment of each section of the winding
unit 2, and the like.
The operation switch 42 is a switch for switching operation and
stop of the winding unit 2, and is installed at the lower part of
the operation panel 25. The operation switch 42 includes a movable
portion 42a movable towards the front and the back. When the movable
portion 42a is pushed into the rear side, the winding unit 2 is in
the operation state. When the movable portion 42a is pulled out to
the front side, the winding unit 2 is in the stop state.
The two alarm lamps 43, 44 are arranged on both left and right
sides of the operation button group 41. The two alarm lamps 43, 44
respectively indicate the operation state of the winding unit 2 to
the operator. One alarmlamp 43is agreenalarmlampthatemits green
light, and the other alarm lamp 44 is a red alarm lamp that emits
redlight. Thegreenalarmlamp43isusedfor, for example, notifying
the operator that the package P is close to full-wound during the
yarn winding. The red alarm lamp 44 is used for, for example,
notifying the operator that the yarn winding operation cannot be
normally carried out due to generation of abnormality in the winding
unit 2.
Next, a description will be made on the unit control section
26. FIG. 4 is a block diagram schematically illustrating an
electrical configuration in one winding unit 2. The unit control
section 26 illustrated in FIG. 4 is configured by a CPU (Central
Processing Unit), which is an arithmetic processing unit, a ROM
(Read-Only Memory) storing programs to be executed by the CPU and
datausedinthe program, a RAM (RandomAccessMemory) for temporarily
storing data at the time of program execution, and the like.
As illustrated in FIG. 4, the unit control section 26 is
electrically connected to the peg driving section 28, the unwinding
assisting device driving section 29, the yarn filler 19, the tension
applying device driving section 30, the yarn joining device 21, the
lower yarn guiding member driving section 31, the yarn clearer 22,
the upper yarn guiding member driving section 32, the drum driving
section 27, and the operation panel 25. The unit control section 26
executes the control program stored in the ROM by the CPU based on
the command from the machine control device 4 (see FIG. 1) of the
automatic winder 1 to control each section of the winding unit 2 and
cause the winding unit 2 to execute the yarn winding operation.
Furthermore, the unit control section 26includes adisplay data
processing section 35. The display data processing section 35 is
input with the information associated with the thickness of the yarn
Y, the information associatedwiththe hairiness, and the information
associated with the detected yarn defect as data associated with the
state of the yarn Y from the yarn clearer 22 described above. The
display data processing section 35 performs the processing of
converting the detection data associated with the state of the yarn
Y to the data to be displayed on the display section 40.
The information associated with the thickness of the yarn Y
includes, for example, a CV value (unit: %) indicating the degree
of yarn unevenness. The information associated with the hairiness
includes, for example, a hairiness value (unit: %) . The information
associated with the yarn defect includes, for example, thickness and
length of the yarn defect. Alternatively, a plurality of categories
is defined according to the thickness and length of the yarn defect,
and the defined yarn defect category may be displayed.
As illustrated in FIG. 3, since the display section 40 includes
three 7-segment LEDs 40a (with decimal display function), three digit
values can be displayed for a number. For example, "12.3" (unit: %)
can be displayed in the case of the CV value, and "12.3" (unit: % )
canbedisplayedinthecaseofthehairiness value. Forthe thickness
and the length of the yarn defect, "160" and "20" are displayed for
the yarn defect having a thickness of 160% and a length of 20 mm,
for example. To displayboth the thickness and the length ofthe yarn
defect, for example, the thickness and the length may be alternately
displayed for every prescribed period of time. For the yarn defect
category, one alphabet and one character are displayed using two
7-segment LEDs 40a. The display of the numerical value is realized
through the processing of converting the detection data input from
the yarn clearer 22 to the data to be displayed with the 7-segment
LED by the display data processing section 35.
In the display section 40includingthe 7-segment LEDs 40a, only
one of the information associated with the state of the yarn Y can
be displayed, and thus the information to be displayed on the display
section 40 needs to be switched among the plurality of types of
information associated with the state of the yarn Y. For example,
when the operator operates the operation button group 41, the display
data processing section 35 of the unit control section 26 may display
desired information corresponding to such operation on the display
section 40.
Since the information associated with the state of the yarn Y
detected by the yarn clearer 22 is displayed on the display section
40, the operator can easily check, from the information displayed
on the display section 40, the yarn Y in what kind of state is being
wound in each winding unit 2.
Among the information associated with the state of the yarn Y,
the CV value and the hairiness value are constantly acquired by the
yarn clearer 22 while the yarn Y is being wound by the winding section
13. Thus, during the yarn winding, the display data processing
section 35 causes the display section 40 to display the CV value or
the hairiness value of the yarn Y immediately before being wound by
the winding section 13. The operator can check the CV value or the
hairiness value of the yarn Y immediately before being wound by the
winding section 13 in real time. The information of the yarn defect
is displayedonthedisplaysection 40whenthe yarndefect is detected
by the yarn clearer 22. For example, the yarndefect maybe displayed
on the display section 40 until elapse of a predetermined time after
the detection of the yarn defect. Even after the winding of the yarn
Y is resumed, the yarn defect information may be displayed on the
display section 40 when the operator operates the operation button
group 41 at an appropriate timing as necessary.
Furthermore, when the operator checks the information
associated with the state of the yarn Y, the following operations
can be carried out based on such information.
For example, the operator can easily check, from the CV value
displayed on the display section 40, the information on the thickness
of the yarn Y wound by the winding unit 2, specifically, whether the
yarn unevenness is large or small.
In addition, the operator can easily check whether the amount
of hairiness of the yarn Y wound by the winding unit 2 is large or
small from the hairiness value displayed on the display section 40.
If the amount of hairiness is extremely large, the operator can once
stop the winding operation for the relevant winding unit 2, and then
adjust each section of the winding unit 2 so that the hairiness is
reduced. For example, by adjusting the height position of the tube
body driven by t h e unwinding a s s i s t i n g device d r i v i n g s e c t i o n 29 of
t h e unwinding a s s i s t i n g device 16, t h e f r i c t i o n of t h e yarn Y can
be reduced and t h e h a i r i n e s s generated a t t h e t i m e of unwinding can
be suppressed. The h a i r i n e s s can a l s o be suppressed by changing t h e
p o s i t i o n of t h e movable comb t e e t h 20b driven by t h e t e n s i o n applying
device d r i v i n g s e c t i o n 3 0 t o w e a k e n t h e t e n s i o n a p p l i e d b y t h e t e n s i o n
applying device 20. If t h e h a i r i n e s s cannot be s u f f i c i e n t l y
suppressed even with t h e adjustment of t h e t e n s i o n i n t h e tension
applying device 20, t h e h a i r i n e s s can be suppressed by f u r t h e r
lowering a r o t a t i o n speed of t h e t r a v e r s e drum 18 driven by t h e drum
d r i v i n g s e c t i o n 27 of t h e winding s e c t i o n 13 and lowering a winding
speed of t h e package.
The operator can e a s i l y check t h e d e t a i l s of t h e detected yarn
defectfromtheinformationoftheyarndefectdisplayedonthedisplay
s e c t i o n 40. When t h e yarn d e f e c t is d e t e c t e d and t h e yarn Y is c u t
by t h e yarn c l e a r e r 22, whether t h e d e t e c t i o n of t h e yarn d e f e c t and
t h e yarn c u t a r e being c a r r i e d out a s expected can be checked by
checking (sampling) t h e a c t u a l yarn d e f e c t . When performing t h e
sampling of t h e yarn d e f e c t i n a c e r t a i n winding u n i t 2, t h e u n i t
c o n t r o l s e c t i o n 26 of t h e r e l e v a n t winding u n i t 2 does not allow t h e
yarn j o i n i n g device 21 t o perform t h e yarn j o i n i n g o p e r a t i o n so t h a t

is d e t e c t e d and t h e yarn Y is c u t by t h e c u t t e r 22a.
In performing t h e sampling of t h e yarn d e f e c t , when t h e
d e t e c t i o n of t h e yarn d e f e c t and t h e subsequent yarn c u t t i n g a r e
performed i n a c e r t a i n winding u n i t 2, t h e o p e r a t i o n of t h e sampling
of t h e yarn d e f e c t becomes extremely easy i f t h e yarn d e f e c t
information is displayed on t h e d i s p l a y s e c t i o n 40 of t h e r e l e v a n t

contained i n t h e yarn Y and t h e displayed yarn d e f e c t information
without moving from t h e p o s i t i o n of t h e winding u n i t 2 where t h e

be a liquid crystal display. In this case, the plurality of types
of information associated with the state of the yarn Y can be
simultaneously displayed on the display section 40.
The embodiment described above is an example in which the
present invention is applied to the automatic winder 1 including the
pluralityofwindingunits 2, butthe present inventionmaybe applied
on the yarn winding device including only one winding unit 2.
According to the present invention, the state of the yarn wound
by thewinding section is detectedinthe yarn state detecting section.
The detection data is converted to the data to be displayed on the
display sectionby the display data processing section, anddisplayed
on the display section. The operator thus can easily check, from the
information displayed on the display section, the yarn Y in what kind
of state is being wound. Since the information associated with the
hairiness of the yarn to be wound is displayed on the display section
