BOBBIN ACCOMMODATING DEVICE AND AUTOMATIC WINDER
BACKGROUND OF THE INVENTION
1. Field of the Invention
[OOOl] The present invention relates to a bobbin accommodating
device adapted to accommodate yarn absent bobbins discharged from
a winding unit, and an automatic winder including the same.
2. Description of the Related Art
[0002] Conventionally, there. is known an automatic winder
configured by arranging a plurality of winding units side by side.
A bobbin tray type automatic winder, e-g., includes a plurality of
winding units, a bobbin transporting device, a yarn absent bobbin
taking-out device, or the like. The bobbin transporting device
transports to each of the winding units, a bobbin around which a yarn
spun by a spinning machine is wound (hereinafter referred to as a
yarn present bobbin). Each of the winding units forms a package by
unwinding the yarn from the yarn present bobbin.
[0003] Processed bobbins of which yarn has been unwound in each
winding unit (hereinafter referred to as a yarn absent bobbin) are
discharged fromthe winding unit. The dischargedyarnabsentbobbins
aretransportedbytrays ofthebobbintransportingdevices. The yarn
absent bobbin taking-out device takes out the yarn absent bobbins
on the trays of the bobbin transporting device. The yarn absent
bobbins taken out by the yarn absent bobbin taking-out device are
discharged from a yarn absent bobbin chute section. The discharged
yarn absent bobbins are accommodated in a collection box, e.g.
[0004] When the yarnabsent bobbins are dischargedfromthe yarn
absent bobbin chute section, orientation of end portions thereof (a
top-bottom direction) is made uniform. However, after the yarn
absent bobbins pass through the yarn absent bobbin chute section and
are haphazardly introduced into the collection box or the like, the
yarn absent bobbins may jump or the like and change the orientation
of the end portions thereof, leading to disarray with random
orientations. When returning the yarn absentbobbinstothe spinning
machine thereafter, the orientations of the end portions of the yarn
absent bobbins needs to be made uniform again. Therefore, in a case
where the orientations of the end portions of the yarn absent bobbins
are random, an alignment task needs to be performed to make the
5 orientations uniformbefore returning the yarn absent bobbins to the
spinning machine.
[0005] As an art of collecting the bobbins in the collection box
or the likewithuniformorientation ofthe endportions ofthebobbins,
Japanese Unexamined Patent Publication No. 60-81338, e.g., discloses
10 a device adapted to temporarily hold a yarn present bobbin (a
fully-wound bobbin), which is not a yarn absent bobbin, in a hopper
and to accommodate the yarn present bobbin in an accommodation box
thereafter. The accommodation box is partitionedby a separator and
the hopper is arranged in each compartment. Japanese Unexamined
15 Patent Publication No. 6-293473 discloses a device adapted to make
orientation of end portions of yarn present bobbins (fully-wound
bobbins) uniform while moving a chute and to hold the yarn present
bobbins in a collection box. The device has a configuration in which'
the yarn present bobbins are sequentially collected one by one by
20 moving the chute.

[0041] The r e s i d u a l yarn d e t e c t i n g sensor (not i l l u s t r a t e d ) is
a detectionmeans f o r d e t e c t i n g t h e r e s i d u a l y a r n p r e s e n t bobbinamong
t h e yarn absent bobbins B t r a n s p o r t e d upward along t h e b e l t member
32. The r e s i d u a l yarn d e t e c t i n g sensor is arranged i n a middle of
a path where transportation is performed by the belt n~ember 32. The
residuai yarn present bobbin chute section 35 and the yarn absent
bobbin chute section 36 are arranged in the path where the belt aember
32 transports the yarn absent bobbin B.
[0042] The yarn absent bobbin B of which residual yarn has been
detected by the residual yarn detecting sensor is discharged to the
residual yarn present bobbin chute section 35 as a residual yarn
present bobbin. The residual yarnbobbin chute section 35 is inclined,
and slides the residual yarn present bobbin to introduce into a
collection container (not illustrated) forthe residual yarn bobbin.
[0043] In the meantime, the yarn absent bobbin B having no
residual yarn is discharged to the yarn absent bobbin chute section
36. The yarn absent bobbin chute section 36 is also inclined and
slides the yarn absent bobbin B having no residual yarn to introduce
it into the bobbin accommodating device 40. In the bobbin taking-out
device 13, the yarn absent bobbin B is taken out with the end portion
thereofontheunwindingside (the topside) facingupward. Therefore,
the yarn absent bobbin B having no residual yarn is introduced-from
the yarn absent bobbin chute section 36 into the bobbin accommodating
device 40 in a position in which the end portion thereof on the
unwinding side (the top side) faces in a transporting direction.
[0044] The yarn absent bobbin chute section 36 is arranged from
the bobbin taking-out device 13 towards the bobbin accommodating
device 40. In the present embodiment, since a first introduction port
671 and a second introduction port 672 are arranged in the bobbin
accommodating device 40, a tip end portion of the yarn absent bobbin
chute section 36isbranchedintoa firstguidingpath 371anda second
guidingpath 372 respectivelycorrespondingtothe first introductior~
port 671 and the second introduction port 672.
[0045] At a branching portion of the first guiding path 371 and
the second guiding path 372 of the yarn absent bobbin chute section
36, a separator 38 is installed. The separator 38 switches between
the first introduction port 671 and the second introduction port 672
both serving as an introduction port of the yarn absent bobbin B by
switching directions for guiding the yarn absent bobbin B. The
separator 38 can be swi~ched by a drive source (not illustrated).
The switching is performed by a control section 77 arranged in the
bobbin supplying device 12.
[0046] In F I G . 3, a side of the bobbin taking-out device 13 of
the yarn absent bobbin chute section 36 and a side of the bobbin
accommodating device 40 (a side where the first guiding path 371 and
the second guiding path 372 are arranged) are respectively referred
to as upstreamanddownstream. Atip endportion 381ofthe separator
38 in FIG. 3 faces upstream. A swinging shaft 382 is arranged
downstream of the tip end portion 381. A position where the swinging
shaft 382 is arranged is adjacent to the branching portion of the
first guiding path 371 and the second guiding path 372 and is on a
path where the yarn absent bobbin B passes through. The separator
38 switches the directions for guiding the yarn absent bobbin B by
swinging the tip end portion 381 with the swinging shaft 382 as a
center.
[0047] F I G . 12 illustrates an alternative embodiment of the
separator 38. The tip end portion 381 of the separator 38 in F I G .
12 faces downstream. The swinging shaft 382 is arranged upstream of
the tip end portion 381. A position where the swinging shaft 382 is
arranged is away from the branching portion of the first guiding path
371 and the second guiding path 372 and is off the path where the
yarn absent bobbin B passes through. The separator 38 switches
directions for guiding the yarn absent bobbin B by swinging the tip
end portion 381 with the swinging shzft 382 as a center. In a case
of this alternative embodiment, even when the yarn absent bobbin B
is introduced while the separator 38 is swinging, the yarn absent
bobbin B is not likely to be sandwiched between the separator 38 and
a side of the yarn absent bobbin chute section 36.
[0048] Next, a configuration of the bobbin accommodating device
40 of the present invention will be described in more detail. As
illustrated in F I G . 3, in the present invention, the bobbin
accommodating device 40 is installed above and across the rocking
and transporting section 29 of the bobbin moving section 26.
[0049] For the sake of convenience, a side where the yarn absent
bobbin B is introduced from the yarn absent bobbin chute section 36
@ is referred to as a front side of the bobbin accommodating device
40 and a side opposite to the front side is referred to as a rear

51, a second holding section 612 and a second accommodating section
712 are respectively arranged as the holding section 61 and the
accommodating section 71. In the present embodiment, the bobbin
15 accommodating device 40 has a substantially left-right symmetric
configuration, and the holding section 61 and the accommodating
section 71 are substantially symmetric about a center in a left-right
direction of the device main body 51. Therefore, a description will
be made on a configuration of the first holding section 611 and the
20 f i r s t a c c o m m o d a t i n g s e c t i o n 7 1 1 b o t h o n t h e l e f t s i d e a n d a d e s c r i p t i o n
on a configuration of the second holding section 612 and the second
accommodating section 712 on the right side may be appropriately
omitted in some cases.
[0051] The devicemain body 51is a part constituting a base body
25 of the bobbin accommodating device 40. A front wall portion 52 is
arranged in a front side of the device main body 51. The first

arranged in the front wall portion 52 respectively corresponding to
the first guiding path 371 and the second guiding path 372 of the
30 yarn absent bobbin chute section 36. A cover (not il-lustrated) is
arranged on an upper part of the device main body 51 to prevent the
yarn absent bobbin B from bouncing out or the like when the automatic
winder 100 is being operated.
[0052] A rear wall portion 53 facing the front wall portion 52
35 is arranged in a rear side of the device main body 51. Upper surface
portions of the front wall portion 52 and the rear wall portion 53
are coupled by a first coupling section 54 and a second coupling
section 55. Two of the first coupliRg sections 54 are arranged
parallel to each other near a center in the upper surface portions
5 of the front wall portion 52 and the rear wall portion 53. The second
coupling sections 55 are respectively arranged in left end portions
and right end portions of the upper surface portions of the front
wall portion 52 and the rear wall portion 53. Right side portions
and left side portions of the front wall portion 52. and the rear wall
10 portion 53 are coupled by a third coupling section 56 and a fourth
coupling section 57. Lower surfaceportions ofthe front wall portion
52 and the rear wall portion 53 are coupledbya fifth coupling section
58. A sixth coupling section 59 is arranged inside the device main
I body 51 so as to partition between a space where the first holding
section 611 is installed and a space where the second holding section
612 is installed. An opening portion 70 is respectively arranged on
a right side surface and a left side surface of the device main body
51formovinrja c o l l e c t i o n b o x 7 2 i n t o / o u t o f t h e a c c o m m o d a t i n g s e c t i o n
71. The opening portion 70 is a region surrounded by the front wall
portion 52, the rear wall portion 53, the fourth coupling section
57 and the fifth coupling section 58.
[0053] The accommodating section 71 is adapted to accommodate
the yarn absent bobbins B discharged from the holding section 61 in
a plurality of compartments. The accommodating section 71 is
configured to be capable of installing and replacing the collection
box 72. In the present embodiment, the first accommodating section
711 and the second accommodating section 712 are arranged as the
accommodating section 71. The first accommodating section 711 is
configured to be capable of installing and replacing a first
collection box 721, and the second accommodating section 712 is
configured to be capable of installing and replacing a second
collection box 722. Each interior portion of the first collection
box 721 and the second collection box 722 is divided into a plurality
of compartments.
[0054] Installment and replacement of the collection box 72 in
the accommodating section 71is performedthroughthe opening portion
70 arranged in the device main body 51. A placing section 73 adapted
t o p l a c e t ~ e c o l l e c t i o n b o x 7 2is arrangedinthe accommodating section
?1. The placing section 73 is configured to be capable of adjusting
a position in a vertical direction according to a height of the
collectionbox 72. Aregulating section 74 is arrangedinthe placing
section 73. The regulating section 74 is configured to be capable
of adjusting a position in a front-rear direction with respect to
t h e p l a c i n g s e c t i o n 7 3 a c c o r d i n g t o a front-rear sizeofthecollection

in the accommodating section 71 is changed to a collection box
different in size in accordance with the length of the yarn absent
bobbin B, the first collectionbox 721canbe installed in a prescribed
reference position. In the present embodiment, positions of the
placing section 73 and the regulating section 74 are adjusted such
that a front side and an upper end side of the first collection box
721 is positioned in the prescribed reference position.
[0055] As illustrated in FIG. 7, a partition 75 is mounted such
that the interior portions of the first collection box 721 and the
second collection box 722 are each divided into the plurality of
compartments. By inserting the partition 75 into each of the first
collection box 721 and the second collection box 722, each of the
interior portions of the first collection box 721 and the second
collection box 722 can be partitioned into two compartments. The
first collection box 721 is partitioned by the partition 75 into a
first compartment (1-lcompartment) 761anda second compartment (1-2
compartment) 762. The second collection box 722 is partitioned by
the partition 75 into a third compartment (2-1 compartment) 763 and
a fourth compartment (2-2 compartment) 764.
[0056] The first collection box 721 and the second collection
box 722 are, in a state where the partition 75 is inserted, set such
that a length of a short side of each compartment 761, 762, 763 and
764 is shorter than the length of the yarn absent bobbin B. A length
of a long side of each compartment 761, 762, 763 and 764 is set to
be slightly longer than the length of the yarn absent bobbin B. The
p a r t i t i o n 75 can be removed by upwardiy t a k i n g out even i n a s t a t e
where the yarn absent bobbins B a r e accommodated i n t h e f i r s t

[0058] The holding s e c t i o n 61 includes a bottom p o r t i o n 62, a
f i r s t s i d e wall p o r t i o n 63, a second s i d e wall p o r t i o n 64 and a t h i r d
s i d e wall p o r t i o n 65. The bottom p o r t i o n 62 is a member adapted t o

(2-1 compartment) 763 and t h e f o u r t h compartment (2-2 compartment)
764 of t h e second c o l l e c t i o n box 722. The bottom p o r t i o n 62 is
i n s e r t e d i n t o a s l i t f o r m e d i n t h e r e a r w a l l p o r t i o n 53 a n d i s supported
by a s l i t arranged i n t h e f r o n t wall p o r t i o n 52. The bottom portion
62 can be removed from t h e device main body 51 by taking out from
the slits.
[0059] The first side wall portion 63, the second side wall
portion 64 and the third side wall portion 65 are members for
regulating movement oi the yarn absent bobbin B in a horizontal
direction (left-right direction). The first side wall portion 63,
the second side wall portion 64 and the third side wall portion 65
are arranged along long sides, which face each other, of the bottom
portion 62. The first side wall portion 63, the second side wall
portion 64 and the third side wall portion 65 are configured by
arranging sideby side two identical shaped side wall members of which
cross sections are both substantially U-shaped. Lower end portions
of the side wall members 66 are slightly curbed inward. Therefore,
lower end portions of the first side wall portion 63 and the third
side wall portion 65 are slightly curbed so as to be close to each
other, and lower end portions of the second side wall portion 64 and
the third side wall portion 65 are also slightly curbed so as to be
close to each other. By curbing the lower end portions of the first
side wall portion 63 and the second side wall portion 64 and the third
-
side wall portion 65 in such a manner, when discharging a plurality
of yarn absent bobbins B, the yarn absent bobbins B are likely to
collectively fall.
[0060] The front wall portion 52 as a first-1 side wall portion,
and a first-2 side wall portion 68 are arranged in front and rear
1
of the first side wall portion 63, the second side wall portion 64,
andthe third sidewall portion 65. The front wall portion 52 (first-1
side wall portion) and the first-2 side wall portion 68 are members
for regulating movement of the yarn absent bobbin B in a horizontal
direction (front-back direction) (see FIG. 6). The first-2 side wall
portion 68 is arranged across the first coupling section 54 and the
second coupling section 55. The first-2 side wall portion 68 is
extended such that a lower end portion thereof is adjacent to the
bottom portion 62. The first-2 side wall portion 68 includes an
adjustment mechanism for adjusting aposltionaccordingtothelength
of the yarn absent bobbin B. Specifically, the first-2 side wall
portion 68 is configured to be capable of moving in the front-back
direction, in a fixed position with respect to the first co~~pling
section 54 and the second coupling section 55. This allows
accommodation of the yarn absent bobbin B by adjusting the position
of the first-2 side wall portion 68 even when the yarn absent bobbin
B is replaced by a yarn absent bobbin B with a different length. In
the front wall portion 52 (first-1 side wall portion) and the first-2
side wall portion 68, a cushioning member 169 is mounted for reducing
impact at the time of collision of the yarn absent bobbin B introduced
from the yarn absent bobbin chute portion 36.
[0061] A guiding section 87 is arranged in an upper part of the
holding section 61. A through hole parallel to the left-right
direction of the device main body 51 is formed in the guiding section
87, and a shaft 88 is formed through the through hole. The shaft 88
is arranged across the second coupling section 55 and the sixth
coupling section 59 so as to be parallel to the left-right direction
of the device main body 51. The holding section 61 can thus move in
the left-right direction of the device main body 51 along the shaft
88.
[0062] The first holding section 611 can switch positions
between a state where the first side wall portion 63 and the third
side wall portion 65 are above the bottom portion 62 (a state of the
first holding section 611 illustrated in FIGS. 9A and 10C, which is
hereinafter referred to as a "state 1-1") and a state where the second
side wall portion 64 and the third side wall portion 65 are above
the bottom portion 62 (a state of the first holding section 611
illustrated in FIGS. 9C and 10A, which is hereinafter referred to
as a "state 1-2"). Furthermore, the second holding section 612 also
can independently switch positions between a state the first side
wall portion 63 and the third sidewall portion 65 are above thebottom
portion 62 (hereinafter referred to as a "state 2-1") and a state
where the second side wall portion 64 and the third side wall portion
65 is above the bottom portion 62 (hereinafter referred to as a "state
2-2") .
[0063] The holding section 61 includes an allocating and
discharging mechanism 81 adapted to allocate the held yarn absent
bobbins B to each compartment 761, 762, 763 and 764 of the
accommodating section 71. The allocating and discharging mechanism
81 moves the first holding section 611 and the second holding section
61.2 to form a first discharge port 62 between the bottom portion 62
5 and the first side wall portion 63 (see FIG. 9B) and a second discharge
port 83 between the bottom portion 62 and the second side wall portion
64 (see FIG. 10B).
LO0641 The allocating and discharging mechanism 81 includes an
actuator 84. The actuator 84 is held in the first coupling section
10 54. A fixing section 86 is arranged in an upper part of the first
holding section 611. Arod85oftheactuator84 is fixedtothe fixing
section 86. By extending and contracting the rod 85 of the actuator
84, the first holding section 611 can be switched between the "state
1-1" and the "state 1-2". The second holding section 612 can be
15 switched independently between the "state 2-1" and the "state 2-2".
[0065] A held bobbin detecting sensor 91 is a sensor adapted to
detect the amount of the yarn absent bobbins B held in the holding
section 61. In the present embodiment, in a case where the amount
of the yarn absent bobbins B held in the first holding section 611
20 or the second holding section 612 has reached a prescribed amount,
the held bobbin detecting sensor 91 detects the amount of the yarn
absent bobbins B by detecting a position of an upper surface of the
yarn absent bobbin B. A photoelectric sensor including a light
projecting/receiving section 92 and a mirror section 93 is used as
25 the heldbobbin detecting sensor 91. The l i g h t p r o j e c t i n g / r e c e i v i n g
section 92 is arranged in the third coupling section 56 of the device
mainbody 51. Themirror section 93 is arrangedon the sixth coupling
section 59 of the device main body 51. Through holes 99 are formed
in each ofthe first sidewall portion 63, the second side wall portion
30 64 and the third side wall portion 65 to allow light from the light
projecting/receiving section 92 to reflect in the mirror section 93
through the through holes 99.
[0066] The held bobbin detecting sensor 91 is configured such
that when aprescribedamountofthe yarn absent bobbins Bis collected
35 in the holding section 61, and thereafter the upper surface of the
yarn absent bobbin B blocks the light fram the light
@ proj ecting/receiving section 92, the light pro j ecting/receiving
section 92 detects the blocked light and inputs a detection signal
to a control section 77 (see FIGS. 9A and 10A). The control section
5 77 activates the actuator 84 based on the detection signal from the
heldbobbin detecting sensor 91to discharge fromthe holding section
61, the yarn absent bobbins B held in the holding section 61.
[0067] This operation will be described with the first holding
section 611 as an example. As illustrated in FIG. 9A, when a
10 prescribed amount of the yarn absent bobbins B is held in the first
holding section 611 under the "state 1-l", and thereafter the upper
surface of the yarn absent bobbin B blocks the light from the light
projecting/receiving section 92, the held bobbin detecting sensor
91 inputs the detection signal to the control section 77. As
15 illustrated in FIG. 9B, the control section 77 activates the actuator
84 basedon the detection signal fromtheheldbobbindetecting sensor
91 to shift the first holding section 61 from the "state 1-1" in FIG.
9A to the "state 1-2" in FIG. 9C. In a process of shifting frorn~the-
"state 1-1" to the "state 1-2", when the first discharge port 82 is
20 formed between the bottom portion 62 and the first side wall portion
63, the yarn absent bobbins B held in the first holding section 611
are discharged from the first holding section 611 to the first
compartment (1-1 compartment) 761. As illustrated in FIG. 9C, when
the first holding section 611 reaches the "state 1-2", the actuator
25 84 stops and, in this state, the first holding section 611 continues
to hold the yarn absent bobbins B.
[0068] The yarn absent bobbins B are continuously held from the
state in FIG. 9C and, as illustrated in FIG. 10A, when a prescribed
amount ofthe yarnabsentbobbins Bisheldinthe first holding section
30 611 under the "state 1-2", and thereafter the upper surface of the
yarn absent bobbin Bblocks light fromthe l i g h t p r o j e c t i n g / r e c e i v i n g
section 92, the held bobbin detecting sensor 91 inputs the detection
signal to the control section 77. As illustrated in FIG. 10B, the
control section 77 activates the actuator 84 based on the detection
35 signal from the held bobbin detecting sensor 91 to shift the first
holding section 611 from the "state 1-2" in FIG. 10A to the "state 8 1-1" in F I G . 10C. In a process of shifting from the "state 1-2" to
the "state 1-I", when the second discharge port 83 is formed between
the bottom portion 62 and the second side wall portion 64, the yarn
5 absent bobbins B held in the first holding section 611 are discharged
from the first holding section 611 to the second compartment (1-2
compartment) 762. As illustrated in F I G . 10C, when the first holding
section 611 reaches the "state 1-I", the actuator 84 stops and, in
this state, the first holding section 611 continues to hold the yarn
10 absent bobbins B.
[0069] A collection box detecting sensor 94 is a sensor adapted
to detect an installation state of the collection box 72. In the
present embodiment, the collection box detecting sensor 94 is
installedineachofthe firstaccommodatingsection711andthesecond
15 accommodating section 712. Aphotoelectric sensor including a light
emitting section 95 and a light receiving section 96 is used as the
collection box detecting sensor 94. A reflecting section 97 adapted
to reflect light from the light emitting section 9-5 towards the light
receiving section 96 is also arranged. The light emitting section
20 95 and the light receiving section 96 are arranged in the fourth
coupling section57 ofthedevicemainbody51. Thereflectingsection
97 is swingably supported by a shaft 98 arranged across an interior
portion of the device main body 51 in a front-rear direction.
[0070] In a case where the collection box 72 is installed in the
25 accommodating section 71, the reflecting section 97 is pushed by the
collection box 72, thereby being upright (see F I G . 8B). The
reflecting section 97 is, in a state of being upright, configured
to reflect the light of the light emltting section 95 towards the
light receiving section 96. In a case where the collection box 72
30 is not installed in the accommodating section 71 (including a case
where the collection box 72 is not properly installed in a prescribed
position, e.g., a case where the collection box 72 is not fully pushed
into an interior portion of the accommodating section 71), the
reflecting section 97 is in an inclined state (see F I G . 8A). The
35 reflectingsection 97 is configured, intheinclinedstate, to reflect
the light of the light emitting section 95 in a direction where the
light receiving section 96 cannot receive the light.
[0071] The collectionboxdetecting sensor 94 is configrlredsuch
that in a case where the collection box 72 is instalied in the
5 accommodating section 71, the light receiving section 96 detects the
light from the light emitting section 95, which is reflected by the
reflecting section 97, and inputs a detection signal to the control
section 77. In this case, the control section 77, based on the
I detection signal fromthe collection box detecting sensor 94, brings
I
10 the holding section 61 into a state where the yarn absent bobbins
B can be discharged. In a case where the collection box 72 is not
installed in the accommodating section 71 (including the case of not
, beingproperlyinstalled), since the reflectingsection 97isinclined,
the light from the light emitting section 95 is not detected by the
15 light receiving section 96. In this case, the control section, based
on the detection signal from the collection box detecting sensor 94,
brings the holding section 61 into a state where the yarn absent
bobbins B cannot be discharged.
[0072] The collection box detecting sensor 94 doubles as an
20 accommodated bobbin amount detecting sensor. The collection box
detectingsensor 94 astheaccommodatedbobbinamountdetectingsensor
detects the amount of the yarn absent bobbins B accommodated in the
collection box 72. The collection box detecting sensor 94 serving
as the accommodatedbobbin amount detecting sensor is configured such
25 that when a prescribed amount of the yarn absent bobbins B is
accommodated in the collection box 72, and thereafter the upper
surface of the yarn absent bobbins B blocks the light from the light
emitting section 95 orthelightreflectedfromthe reflecting section

30 the detection signal to the control section 77. The control section
77 activates a notifying section such as a lamp based on the detection
signal from the collection box detecting sensor 94, which serves as
the accommodated bobbin amount detecting sensor, to notify to an
operator that the prescribed amount of the yarn absent bobbins B has
35 been collected.
[0073] In the present embodiment, priority is set between the
@ first accommodating section 711 on a left side and the second
accomiiodating section 712 on a right side. The first accommodating
section 711 on the left side is set as a priority machine adapted
5 to accommodate the yarn absent bobbins B on a priority basis. The
second accommodating section 712 on the right side is set as an
auxiliary machine adapted to accommodate the yarn absent bobbins B
inacasewherethe first accommodating section 711setasthepriority
machine is unable to accommodate the yarn absent bobbins B. Cases
10 where the first accommodating section 711 is unable to accommodate
the yarn absent bobbins B are: (1) a case where the yarn absent bobbins
Bare collectedinthe f i r s t c o l l e c t i o n b o x 7 2 1 o f t h e first collecting
section 711 and the amount thereof has reached a prescribed amount;
and (2) a case where the first collection box 721 of the first
15 accommodating section 711 is not installed (including a case of not
beingproperlyinstalled). Incase ( 2 ) , t h e r e i s i n c l u d e d a c a s e w h e r e
the operator is replacing the first collection box 721 after the yarn
absent bobbins B are collected in the first collection box 721. In
this case, by activating a drive source of the separator 38 in the
20 yarn absent bobbin chute section 36 and switching directions for
guiding the yarn absent bobbins B, the control section 77 switches
from the first introduction port 671 (the first accommodating section
711) to the second introduction port 672 (the second accommodating
section 712) .
25 [0074] With the bobbin accommodating device 40 and the automatic .
winder 100 according to the above-described present embodiment, the
following effects are provided.
[0075] The bobbin accommodating device 40 includes the holding
section 6 1 a d a p t e d t o t e m p o r a r i l y h o l d t h e yarn absent bobbins Bwhile
30 maintaining uniform orientation of the end portions thereof and the
accommodating section 71 adapted to allocate to a plurality of
compartments and to accommodate the yarn absent bobbins B discharged
from the holding section 61. Since the holding section 61
collectivelydischarges aprescribedamountoftheyarnabsentbobbins
35 B, the yarn absent bobbins B can be prevented from jumping in the
accommodating section 71, leading to a change in the orientation of
the end portions thereof, thereby allowing collection of the yarn
absent bobbins with the uniform orientation of the end portions
thereof. Furthermore, since the yarn absent bobbins B held in the
holding section 61 are allocated in the plurality of compartments
of the accommodating section 71 and are discharged, the yarn absent
bobbins B can be equally accommodated without being concentratedly
discharged to one part of the accommodating section 71.
[0076] The bobbin accommodating device 40 is configured to be
capable of installing therein, the collection box 72 adapted to
accommodate the yarn absent bobbins B. The collection box 72 has an
interior portion dividedinto apluralityof compartments. Since the
yarn absent bobbins B can be directly accommodated in the collection
box 72, which the operator can handle, it is not required for the
operator to collect the yarn absent bobbins B in another container
for returning the yarn absent bobbins B to a spinning machine.
Collecting operation of the yarn absent bobbins B can thus be easily
performed in a short time.
[0077] In a case where the amount of the yarn absent bobbins B
held in the holding section 61 has reached a prescribed amount, the
bobbin accommodating device 40 causes the yarn absent bobbins B held
in the holding section 61 to be discharged from the holding section
61. Since this allows the holding section 61 to hold an appropriate
amount of the yarn absent bobbins B, the yarn absent bobbin B does
not spill over the holding section 61. Furthermore, since the yarn
absent bobbins B are not discharged to the accommodating section 71
in a small amount, the yarn absent bobbins B can be prevented from
jumping in the accommodating section 71, leading to a change in the
orientation of the end portions thereof.
[0078] In the bobbin accommodating device 40, the allocating and
discharging mechanism 81 moves the first side wall portion 63 and
the second side wall portion 64 to form the first discharge port 82
between the bottom portion 62 and the first side wall portion 63,
and the second discharge port 83 between the bottom portion 62 and
the second side wall portion 64. The yarn absent bobbins B can thus
be allocated with a simple configuration.
[0079] In the bobbin accommodating device 40, by simultaneously
moving the first side wall portion 63 and the second side wall portion
64 with respect to the bottom portion 62, the allocating and
discharging mechanism 81 alternately forms the first discharge port
82 and the second discharge port 83. The yarn absent bobbins B held
in the holding section 61 can thus be moved in a parallel manner and
discharged to the accommodating section 71, thereby allowing
suppression of impact of the yarn absent bobbins B at the time of
discharging the yarn absent bobbins B to the accommodating section
71.
[0080] In the bobbin accommodating device 40, the bottomportion
62 is configured in a removable manner. Therefore, in cases where
the yarn absent bobbins B are stuck in the holding section 61, or
the like, the operator can easily perform maintenance on the holding
section 61 by removing the bottom portion 62.
[0081] In the bobbin accommodating device 40, the holding
section 61 includes the front wall portion 52 as the first-1 side
wall portion and the first-2 side wall portion 68 both arranged along
short sides of the bottom portion 62, and an adjustment mechanism
(not illustrated) adapted to adjust an interval of the front wall
portion 52 as the first-1 side wall portion and the first-2 side wall
portion 68. Therefore, size of the holding section 61 in a
longitudinal direction can be adjusted in accordance with the size
of the yarn absent bobbins B to be temporarily held, thereby allowing
accommodation of a plurality of types of the yarn absent bobbins B.
COO821 In a case of detecting that the collection box 72 is not
installed in the accommodating section 71, the bobbin accommodating
device 40 stops the discharge of the yarn absent bobbins B by the
holding section 61. The yarn absent bobbins B can thus be prevented
from being discharged from the holding section 61 in a state where
the collection box 72 is not installed in the accommodating section
71.
[0083] In the bobbin accommodating device 40, the collection box
detecting sensor 94 doubles as the accommodated bobbin amount
detecting sensor adapted to detect the amount of the yarn absent
bobbins Baccommodatedinthe collectionbox 72. Since the collection
box detecting sensor 94 doubles a; the accommodated bobbin amount
detecting sensor, the number of sensors canbe reduced. Furthermore,
when the accommodated bobbin amount detecting sensor detects that
the amount ofthe yarn absent bobbins B accommodatedinthe collection
box 72 has reached a prescribed amount, the discharge of the yarn
absent bobbins B from the holding section 61 is stopped, thereby
preventingthe yarnabsent bobbins B fromspillingoverthe collection
box 72.
[0084] The bobbin accommodating device 40 includes at least two
of each the holding section 61 and the accommodating section 71
arranged side by side. The first accommodating section 711 is set
astheprioritymachineadaptedtoaccommodatethe yarnabsent bobbins
B on a priority basis and the second accommodating section 712 is
set as the auxiliary machine adapted to accommodate the yarn absent
bobbins Bina casewheretheprioritymachineis unableto accommodate
the yarn absent bobbins 13. By arranging a plurality, of the
accommc,dating sections 711 and 712, even when collecting operation
of the yarn absent bobbins B is being performed in one of the
accommodating sections, the yarnabsent bobbins B canbe continuously
accommodated. Furthermore, setting priority between the collecting
section 711 and the collecting section 712 allows prevention of the
accommodating sections 711 and 712 from both being full around the
same time.
[0085] In the automatic winder 100, the bobbin accommodating
device 40 is arranged on a part of the bobbin supplying device 12.
This allows supply of the yarn present bobbins YB and accommodation
ofthe yarnabsent bobbins Bbothtobeperformedinpositions adjacent
to each other, thereby minimizing movement of the operator.
Furthermore, a space required for installing the automatic winder
100 can be reduced.
[0086] In the automatic winder 100, the yarn absent bobbin chute
section 36 determines whether to guide the yarn absent bobbins B to
the priority machine or to the auxiliary machine according to a state
dfthe prioritymachine. Thus, even when collecting operation ofthe
yarn absent bobbins B is being performed in one of the accommodating
sections 71, the yarn absent bobbins B can be continuously
acccmmodated in the other of the collecting sections 71.
5 [0087] (Embodiment 2) Next, an automatic winder according to
Embodiment 2 of the present invention will be described by use of
FIGS. 13 to 17. The automatic winder of the second embodiment is
I
mainly different from the automatic winder 100 of Embodiment 1 in
I terms of a configuration of a holding section 61' of a bobbin
10 accommodating device 140, however, identical collection boxes 72,
721, 722 may be used.
[0088] As illustrate din FIGS. 13to17, thebobbinaccommodating
device 140 includes a device main body 51'' the holding section 61'
and an accommodating section 71'. A first holding section 611' and
15 a second holding section 612' are arranged as the holding section
61'. In a case where the amount of the held yarn absent bobbins B
has reached a prescribed amount, the first holding section 611'
rotates between the first compartment (1-1 compartment) 761 and the
second compartment (1-2 compartment) 762 of the first collection box
20 721 and discharges the held yarn absent bobbins B. In a case where
the amount of held yarn absent bobbins B has reached a prescribed
amount, the second holding section 612' rotates between the third
compartment (2-1 compartment) 763 and the fourth compartment (2-2
compartment) 764 of the second collection box 722 and discharges the
25 held yarn absent bobbins B.
[0089] The holding section 61' includes the bottom portion 62''
the first side wall portion 63' and the second side wall portion 64'.
The bottom portion 62' is a member adapted to regulate movement of
the yarnabsent bobbins Binaver.tical direction, which is adir~ction
30 where the yarnabsent bobbins B fall. Thebottomportion 62' includes
a first bottom portion 621 and a second bottom portion 622 both having
long sides and short sides. The first bottom portion 621 and the
second bottom portion 622 each has a shape symmetric to each other.
The first bottom portion 621 and the second bottom portion 622 are
35 swingably arranged with respect to the device main body 51' with a
shaft 67 as an axial center. The first bottom portion 621 and the
second bottom portion 622 each has a base portion 623, a first
receiving section 624 and a second receiving section 625. The first
receiving section 624 and the second receiving section 625 are each
arranged in a unified manner with the base portion 623 on a side of
the base portion 623. The first receiving section 624 is arranged
in a unified manner with the base portion 623 on a side of the base
portion 623 where the first bottom portion 621 and the second bottom
portion 622 are adjacent to each other, and the second receiving
section 625 is arranged in a unified manner with the base portion
623 on a side opposite to the side of the base portion 623 where the
first bottomportion 621andthe secondbottomportion 622 areadjacent
to each other. A shape of a cross section formed by cutting the first
bottom portion 621 and the second bottom portion 622 vertically with
respect to the shaft 67 is a recess such that the base portion 623,
the first receiving section 624 and the second receiving section 625
can hold the yarn absent bobbins B.
[2!290] The first bottomportion 621andthe secondbottomportion
622 are mounted to a fixing section 66', each arranging the first
receiving section 624 adjacent to each of them. The second receiving
section 625 is inverted at substantially 90 degrees with respect to
the first receiving section 624. The fixing section 66' is mounted
to the shaft 67. The shaft 67 is rotatably arranged across the front
wall portion 52 and the rear wall portion 53 of the device main body
51'. The shaft 67 is, in the first holding section 611'' installed
above and across the partition 75 adapted to partition between the
first compartment (1-1 compartment) 761 and the second compartment
(1-2 compartment) 762 of the first collection box 721 and is, in the
second holding section 612" installed above and across the third
compartment (2-1 compartment) 763 and the fourth compartment (2-2
compartment) 764 of the second collection box 722.
[0091] The first side wall portion 63' and the second side wall
portion 64' aremembersadaptedtoregulatemovementoftheyarnabsent
bobbin B in a horizontal direction (left-side direction). The first
side wall portion 63' is arranged along a free end of the second
receiving section 625 of the first bottom portion 621. The second
side wall portion 64' is arranged along a free end of the second
receiving section 625 of the second bottom portion 622. The first
side wall portlon 63' and the second side wall portion 64' are
supported by each swinging section 68'. Each swinging section 68'
isarrangedonashaft 69inahangingmanner. The shaft 69isarranged
across the front wall portion 52 and the rear wall portion 53. The
first side wall portion 63' and the second side wall portion 64' can
thus be swung with respect to the device main body 51.
[0092] A cam 87' as the guiding section 87 is fixed to the shaft
67, which supports the bottom portion 62, in a side of the front side
wall portion 52 of the device main body 51'. A follower 89, which
abuts against the cam 87'' is arranged in the swinging section 68'
adapted to support the first side wall portion 63' and the second
side wall portion 64'. In a case where the bottom portion 62' is
inclined to the first bottom portion 621 side, the cam 87' has a shape
by which the cam 87' pushes up the first side wall portion 63' via
the follower 89 to form a first discharge port 82' between the first
bottom portion 621 and the first side wall portion 63' (see FIG. 16B)
andat this time, a seconddischargeport83' between the secondbottom
portion 622 and the second side wall portion 64' is closed since the
second side wall portion 64' is not pushed up. In a case where the
bottom portion 62' is inclined to the second bottom portion 622 side,
the cam 87' has a shape by which the cam 87' pushes up the second
side wall portion 64 via the follower 89 to form the second discharge
port 83' between the second bottom portion 622 and the second side
wall portion 63' (see FIG. 17B) and at this time, the first discharge
port 82' between the first bottom portion 621 and the first side wall
portion 63' is closed since the first side wall portion 63' is not
pushed up.
[0093] The first holding section 611 is capable of switching
positions between a state where the bottom portion 62' is inclined
to the second bottom portion 622 side and the first discharge port
82' between the first bottom portion 621 and the first side wall
portion 63' is closed (a state of the first holding section 611'
illustrated in FIGS. 1.6A and 17Cf which is hereinafter referred to
as a "state 3-1") and a state where the bottom portion 62' is inclined
to the first bottom portion 621 side and the second discharge port
83' between the second bottom portion 622 and the second side wall
5 portion 64' is closed (a state of the first holding section 611'
illustrated in F I G S . 16C and 17Af which is hereinafter referred to
as a "state 3-2"). The second holding section 612' is also capable
of switching positions between a state where the bottom portion 62'
is inclined to the second bottom portion 622 side and the first
10 discharge port 82' between the first bottom portion 621 and the first
side wall portion 63' is closed (hereinafter referred to as a "state
4-1") and a state where the bottom portion 62' is inclined to the
first bottom portion 621 side and the second discharge port 83'
between the secondbottomportion 622 and the second sidewall portion
15 64' is closed (hereinafter referred to as a "state 4-2").
[0094] The holding section 61' includes an allocating and
discharging mechanism 181 adapted to allocate the held yarn absent
bobbins B to each compartment 761, 762, 763 and 764 of the
accommodating section 71. The allocating and discharging mechanism
20 18lmoves (swings) the first holding section 611andthe secondholding
section 612 to form the first discharge port 82' between the bottom
portion 62' and the first side wall portion 63' (see F I G . 16B) and
the second discharge port 83' between the bottom portion 62' and the
second side wall portion 64' (see F I G . 17B).
25 [0095] The allocating and dischargingmechanism 1.81includes an
actuator 84'. The actuator 84' is arranged in an outer side of the
front wall portion 52. The actuator 84' includes an extendable rod
85'. Alever86' isarrangedintheshaft67, whichsupportsthebottom
portion 62'. The rod 85' of the actuator 84' is coupled to the lever
30 86'. By extending/contracting the rod 85' of the actuator 84' and
thereby swinging the bottom portion 62'' the first holding section
611' can be switched between the "state 3-1" and the "state 3-2".
The second holding section 612' can be switched between the "state
4-1" and the "state 4-2".

in FIG. 17Bf the control section activates the actuator 84' based
~ on the detection signal from the held bobbin detecting sensor 91 to
shift the first holding section 611' from the "state 3-2" in FIG.
17A to the "state 3-1" in FIG. 17C. In a process of shifting from
10 the "state 3-2" to the "state 3-l", when the second discharge port
83' is formed between the second bottom portion 622 and the second
side wall portion 64'' the yarn absent bobbins B held in the first
holding section 611' are discharged from the first holding section
611' tothe second compartment (compartment l-2) 762. As illustrated
15 in FIG. 17Cf when the first holding section 611' reaches the "state
3-1"' the actuator 84' stops and, in this state, the first holding
section 611' continues to hold the yarn absent bobbins B.
[0099] With the bobbin accommodating device 140 and the
automaticwinder according tothe above-described second embodiment,
20 the following effects are provided.
[OlOO] In the bobbin accommodating device 140, the allocating
a n d d i s c h a r g i n g m e c h a n i s m 1 8 1 a l t e r n a t e l y i n c l i n e s t h e b o t t o m p o r t i o n
62' to the first bottom portion 621 side and the second bottom portion
622 side. The allocating and discharging mechanism 181 forms the
25 first discharge port 82' with the first side wall portion 63' in a
case where the bottom portion 62' is inclined to the first bottom
portion 621 side, and forms the second discharge port 83' with the
second side wall portion 64' in a case where the bottom portion 62'
is inclined to the second bottom portion 622 side. The yarn absent
30 bobbins B can thus be dischargedwithoutbeing sandwichedbythe first
discharge port 82'' the second discharge port 83'' and the like.
[OlOlj In the bobbin accommodating device 140, the first bottom
portion 621 and the second bottom portion 622 each having the base
portion 623, the first receiving section 624 and the second receiving
35 section 625, are symmetrictoeachother. The firstreceivingsection
624 is arranged in a unified manner with the base portion 623.on a e side of the bottom portion 623 where the first bottom portion 621
and the second bottom portion 622 are adjacent to each other, and
the second receiving section 625 is arranged in a unified manner with
5 thebase portion 623 on a side opposite tothe side ofthe base portion
623 where the first bottom portion 621 and the second bottom portion
622 are adjacent to each other. A shape of a cross section, which
is formed by the base portion 623, the first receiving section 624
and the second receiving section 625, in a direction vertical with
