[Technical Field]
[ OOOl] The present invention relates to a textile machine.
Specifically, the present invention relates to a configuration for
improving workability of an operator in a textile machine.
[Background Art]
[0002] In a textile machine such as an automatic winder, a
spinning machine, and the like, there has been conventionally
proposed various types of configurations for notifying, upon
occurrence of a defect, the operator ofthe occurrence ofthe defect
andthe area where thedefect occurred. PatentDocument1discloses
an automatic winder including this type of configuration.
[0003] The automatic winder of Patent Document 1 includes a
plurality of winding units arranged side by side, and a yarn length
counter adapted to store a length and the like of a yarn wound by
thepluralityofwindingunits. Agreenlampis attachedtoa front
side of each winding unit. A warning lamp is attached to an upper
part of the yarn length counter. When a defect occurs in any of
the winding units, the automatic winder lights the warning lamp
and also lights the green lamp of the relevant winding unit. The
operator can thus immediately understand the occurrence of defect
and the area where the defect occurred.

[Summary of the Invention]
[Problems to be Solved by the Invention]
[OOOS] The textile machine such as the automatic winder is
provided with a plurality of yarn processing devices adapted to
perform processes associated with a yarn. Therefore, a portion

haspoorvisibilityexistsinproximitytoa yarnpath. Furthermore,
when a defect such as entangling of the yarn occurs, the operator
needs to manually remove the defect. Thus, when a defect occurs
at a portion shaded by other yarn processing devices and the like,
theworkof specifyingthe defect andtheworkof removingthedefect
become difficult.
[0006] In Patent Document 1, the warning lamp is for indicating
the presence and absence of occurrence of a defect, and does not
illuminate the area that requires the work of the operator.
Furthermore, the green lamp is arranged on the front side of the
winding unit so that the operator can easily check the occurrence
of the defect, and does not illuminate the area that requires the
work of the operator.
[0007] The present inventionhas beenmade inview ofthe above
circumstances, and a main object thereof is to provide a textile
machine in which visibility of an area that requires work of an
operator is improved.
[Means for Solving the Problems and Effects]
[0008] The problems to be solved by the present invention is
as described above, and the means for solving the problems and the
effects thereof will be described next.
[0009] According to one aspect ofthe present invention, there
is provided a textile machine including an illuminating section
adapted to illuminate an area that requires work of an operator
from an outer side to brighten the area.
[OOlO] Thus, the area that requires the work of the operator
can be illuminated with the illuminating section to improve the
visibility, whereby the workability of the work for checking the
defect, the work for removing the defect, or the like, for example,
can be improved. .
[OOll] In the above-described textile machine, the
illuminating section is preferablyprovided such that illumination
light is directed toward the area that requires the work of the
operator or such that the illumination light is guided to the area.
D@ieHf 11 -T@G,- ~Ee~&%e&~d~&quires the work of the operator
can be accurately illuminated, and hence the workability of the
I
work by t h e operator can be f u r t h e r improved.
[0013] In t h e above-described t e x t i l e machine, the

work from a s i d e on which t h e o p e r a t o r s t o p s t o c a r r y out t h e work.
[0014] Thus, t h e portion seen from t h e operator of t h e area
t h a t r e q u i r e s t he w o r k o f t h e operator becomes p a r t i c u l a r l y b r i g h t ,
and hence t h e workability of t h e operator can be f u r t h e r improved.

[0016] Thus, t h e workability of t h e work f o r checking t h e
d e f e c t , thework f o r r e m o v i n g t h e d e f e c t , o r t h e l i k e canbe improved
by i l l u m i n a t i n g t h e area where t h e d e f e c t occurred.

[0018] Thus, t h e occurrence o f t h e d e f e c t can be n o t i f i e d t o
t h e o p e r a t o r . Since t h e l i g h t i n g t i m e can be reduced compared t o
t h e c o n f i g u r a t i o n i n which t h e i l l u m i n a t i n g s e c t i o n is always
l i g h t e d , t h e l i f e s p a n of t h e i l l u m i n a t i n g s e c t i o n can be extended.
[0019] In t h e above-described t e x t i l e machine, a l i g h t i n g
c o l o r o f t h e i l l u m i n a t i n g s e c t i o n is changeable, t h e l i g h t i n g color
p r e f e r a b l y being changed according t o d e t e c t i o n content of t h e

following configuration. Specifically, each ofthe units includes
a unit frame arranged on a boundary between the adjacent units and
adapted to support a plurality of yarn processing devices which
carry out processes associated with a yarn. The illuminating
section illuminates a space between the adjacent unit frames.
[ 0 0 2 4 ] Thus, a space surrounded by two adjacent unit frames
is shaded by the unit frames and the yarn processing devices and
thus becomes dark, and hence such a portion can be illuminated to
improve the workability of the operator.
[ 0 0 2 5 ] In the above-described textile machine, the
illuminating section preferably illuminates a lower side of the
winding section.
[0026] Since the package is generally large, the space on the
lower side of the package is likely to be shaded easily, and thus
such a portion can be illuminated to improve the workability of
the operator.

between the adjacent units and adapted to support a plurality of
yarn processing devices which carry out processes associated with
the yarn. The illuminating section illuminates a space located on
a lower side of the winding section and between the adjacent unit
I frames.
[ 0 0 2 8 ] Thus, the space surrounded by the unit frames and
located on the lower side of the winding section (package) becomes
very dark, and hence such a portion can be illuminated to improve
the workability of the operator.

[Modes for Carrying Out the Invention]
[0042] A first embodiment of the present invention will be
hereinafter described with reference to the drawings. FIG. 1 is
a schematic front view of an automatic winder 1 according to the
first embodiment.
[0043] The automatic winder (textile machine) 1 illustrated
in FIG. 1 includes a plurality of winding units (units) 2 arranged
side by side, a machine control device 3, a doffing device 4, and
a blower box (not illustrated) as main components.
[0044] The winding unit 2 includes a yarn supplying section
7, ayarnstoragedevice 5, andawindingsection8 asmaincomponents.
The winding unit 2 is configured to unwind a yarn 20 of a yarn
supplying bobbin 21 supplied to the yarn supplying section 7, and
temporarily store the unwound yarn 20 in the yarn storage device
5, and thereafter, wind the unwound yarn 20 around a winding bobbin
22 in the winding section 8 to form a package 30. The winding unit
2 also includes a unit frame 6 provided on one side (right side)
in a left and right direction in front view. The unit frame 6 is
arranged at a boundary between adjacent winding units 2 (i-e.,
arranged to divide the adjacent winding sections 8 and the like).
The unit frame 6 supports a plurality of yarn processing devices
(devices adapted to perform processes associated with the yarn 20)
arranged in the winding unit 2, and includes therein a unit control
section 25.
[0045] The machine control device 3 is configured as a
microcomputer, and includes a display 65 and an input key 66. The
machine control device 3 is configured to communicate with each
winding unit 2. The operator of the automatic winder 1 operates
the input key 66 to intensively manage the plurality of winding
units 2.
[0046] When the package 30 is fully wound in the winding unit
2 (state where a prescribed amount of the yarn 20 is wound), the

controlled by the machine control device 3.
[0047] Next, a description will be made on a configuration of
the winding unit 2 with reference to FIG. 2. FIG. 2 is a schematic
side view of the winding unit 2.
[0048] Asdescribedabove, thewindingunit2 includesthe yarn
supplying section 7, the yarn storage device 5, and the winding
section 8. "Upstream" and "downstream" respectively refer to

section 25 lights the LED lamp 71 (S107). Thus, the work area
becomes brighter, and the workability of the work by the operator
can be improved. Alternatively, the operator does not need to hold
the illumination by hand, which also improves the workability. In
the present embodiment, the LEDlamp 71is lightedinwhite, placing
significance on brightness.
[0074] Inthe descriptionmade above, theLEDlamp71islighted
when the yarn monitoring device 17 does not detect the presence
of the yarn 20. In place of such a configuration, even when the
yarn monitoring device 17 does not detect the presence of the yarn
20, the pull out of the upper yarn may be further carried out once
or a plurality of times, and the LED lamp 71 may be lighted if the
upper yarn still cannot be pulled out.
[0075] As described above, the automatic winder 1 of the
present embodiment includes the LED lamp 71 adapted to illuminate
the area, which requires the work of the operator due to the
I occurrence of a defect, from the outer side to brighten the area.
Furthermore, in the automatic winder 1 of the present embodiment,
the LED lamp 71 is provided such that the illumination light is
directed toward the area that requires the work of the operator.
[0076] Thus, the area that requires the work of the operator

whereby the workability of the work for checking the defect, the
work for removing the defect, or the like can be improved.
[0077] The automatic winder 1 of the present embodiment
further includes the yarn monitoring device 17 adapted to detect
the occurrence of the defect. The LED lamp 71 starts to be lighted
when the yarn monitoring device 17 detects the defect.
[0078] Thus, the occurrence of the defect can be notified to
the operator. The lighting time can be reduced compared to the
configuration where the LED lamp 71 is always lighted, so that the
lifespan of the LED lamp 71 can be extended.

[0080] Thus, a space surroundedbythe u n i t frame 6 and located
on t h e lower s i d e of the winding s e c t i o n 8 (package 30) becomes
very dark, and such a portion can be i l l u m i n a t e d t o g r e a t l y improve
t h e w o r k a b i l i t y of t h e o p e r a t o r .
[0081] The automatic winder 1 of t h e present embodiment

s u r f a c e of t h e yarn storage r o l l e r 32.
[0084] Thus, t h e surface of t h e yarn s t o r a g e r o l l e r 32 is
i l l u m i n a t e d t o improve t h e v i s i b i l i t y , whereby t h e operator can

yarn 20 t h a t occurs when t h e s u r f a c e of t h e yarn s t o r a g e r o l l e r
32 is damaged can be prevented.
[0085] In t h e automatic winder 1 of t h e present embodiment,

[0086] Thus, the lower side of the yarn storage roller 32 is
shaded by the yarn storage roller 32 itself, and such a portion
can be illuminated to improve the workability of the work of
detaching the yarn 20 attached to the yarn storage roller 32, and
the like.
[0087] The automatic winder 1 of the present embodiment
includes the yarn supplying section 7 adapted to supply the yarn
20, 48. theupper yarnpull-out
section 48 is arranged in proximity to the portion for winding the
yarn 20 from the yarn supplying section 7 in the yarn storage roller
32, and is adapted to suck and pull out the yarn 20 wound around

the vicinity of the upper yarn pull-out section 48.
[0088] When the upper yarn pull-out section 48 cannot catch
the yarn 20 on the upstream of the yarn storage roller 32, the
operator needs to manually detach the yarn 20 in proximity to the
upper yarn pull-out section 48 (in proximity to the upstream end
of the yarn storage roller 32) from the yarn storage roller 32.
Thus, the work by the operator can be smoothly carried out by
illuminating the relevant portion.
[0089] Next, a description will be made on a second embodiment
with reference to F I G . 6. F I G . 6 is a schematic side view of a
