TITLE
TRAVERSE GUIDE, YARN WINDING MACHINE, AND METHOD
FOR PRODUCING TRAVERSE GUIDE
TECHNICAL FIELD
5 [000 1] The present disclosure relates to a traverse guide, a yarn winding
machine, and a method for producing the traverse guide.
BACKGROUND
[0002] A yam winding machine includes a traverse guide configured to
move in a reciprocating rotational manner so as to traverse a yam to be
10 wound by a winding bobbin. For example, a distal end portion of an
arm body member of a traverse guide described in Japanese
Unexamined Patent Publication No. 2013-63807 is provided with a
guide member having a yam hooking portion configured to guide a
yam.
15 .~UMMARY
[0003] The guide member described in Japanese Unexamined Patent
Publication No. 2013-63807 is fixed to the arm body member with
adhesive applied therebetween. Thus, when too little or too much
adhesive is applied, adhesion failure of the guide member may occur.
20 Depending on use conditions of the traverse guide, adhesive strength of
the adhesive may decrease. In these cases, the guide member may
detach. Furthermore, when adhesive is applied, the adhesive may
squeeze out from between the arm body member and the guide member.
In this case, in the adhesive thus squeezing out, or in a gap generated
25 between the arm body member and the guide member due to squeezing
out of the adhesive, a yam may be caught, whereby the yam may be cut.

FP16-0433-00
[0004] T n view of this, the present disclosure aims to provide a traverse
guide, a yarn winding machine, and a method for producing the traverse
guide in which a guide member can be reliably fixed to an arm body
member without applying adhesive.
5 (0005] A traverse guide according to one aspect of the present
disclosure includes: an arm body member having a distal end portion in
a hook-like curved shape and containing a metallic material; and a guide
member integrally fixed to the distal end portion of the arm body
member without adhesive applied therebetween and having a yarn
1 0 hooking portion configured to hook a yam. Hardness of the guide
member is higher than hardness of the arm body member, and at least
part of the guide member other than the yarn hooking portion has an
embedded portion embedded in the distal end portion.

20 DETAILED DESCRIPTION
[0020] An embodiment according to the present disclosure will now be
described in detail with reference to the attached drawings. In the
following description, like elements or elements having like functions
are designated by like numerals, and duplicate description is omitted.
25 [0021] Referring to FIG. 1, an overall configuration of an automatic
winder 1 including a winder unit (yam winding machine) 2 of the
3
FP16-0433-00
present embodiment will be described. Iu the following description,
the terms "upstream" and "downstream" mean upstream and
downstream in a traveling direction of a yam Y during yam winding.
[0022] As depicted in FIG 1, the automatic winder 1 includes a
5 plurality of winder units 2 disposed in parallel and a machine control
device 4. The machine control device 4 controls (manages) operation
of the entire automatic winder 1. The automatic winder 1 may further
include an automatic doffing device (not depicted).
[0023] As depicted in FIG. 2, each winder unit 2 includes a winding
10 unit main body 3 and a unit controller 17 as main components.
[0024] The unit controller 17 includes a central processing unit (CPU),
a random access memory (RAM), a read only memory (ROM), an I/0
port, and a communication port. The ROM stores therein a program
for controlling the respective components of the winder unit 2. The
15 I/0 port and the communication port are connected to respective
sections (described later in detail) and the machine control device 4
included in the winder unit 2 are connected. The I/0 port and the
communication port are configured to enable communication of control
information, for example, therethrough. With this configuration, the
20 unit controller 17 can control operation of the respective sections
included in the winder unit 2.
[0025] The winding unit main body 3 includes a yam supplying section
5, a yam-unwinding assisting device 7, a tension applying device 9, a
yam monitor 11, a splicer device 13, and a winding section (winding
25 member) 15 in a yam traveling path between a yarn supplying bobbin 6
and a contact roller 22.
4
FP16-0433-00
ro026] In a lower portion of the winrler nnit 7., the yam supplying
section 5 is provided. The yam supplying section 5 is configured to be
able to hold the yarn supplying bobbin 6 conveyed by a bobbin
conveying system (not depicted) in a predetennined position.
5 [0027] The yarn-unwinding assisting device 7 assists unwinding of the
yarn Y from the yam supplying bobbin 6 by lowering a regulation
member 8 covering a core tube of the yam supplying bobbin 6 in
conjunction with unwinding of the yarn Y from the yam supplying
bobbin 6. The regulation member 8 comes into contact with a balloon
1 0 of the yam Y that is formed in an upper portion of the yam supplying
bobbin 6 by rotation and centrifugal force of the yam Y unwound from
the yam supplying bobbin 6, and controls the balloon of the yam Y to an
appropriate size, thereby assisting the unwinding of the yarn Y Near
the regulation member 8, a sensor (not depicted) for detecting a chase
15 portion of the yarn supplying bobbin 6 is provided. When this sensor
detects descent of the chase portion, the yam-unwinding assisting
device 7 follows the descent of the chase portion to lower the regulation
member 8 by an air cylinder (not depicted), for example.
[0028] The tension applying device 9 applies a predetermined tension
20 to the traveling yam Y. As the tension applying device 9, for example,
a gate-type device in which movable comb teeth are disposed with
respect to fixed comb teeth can be used. By causing the yam Y to pass
through between the comb teeth meshing with each other while causing
the yarn Y to bend, resistance can be applied to the traveling yam Y to
25 apply an appropriate tension thereto. As the tension applying device 9,
in addition to the above-described gate-type device, for example, a
5
FP16-0433-00
disk-type device can be used.
[0029] The yam monitor 11 includes a sensor (not depicted) for
detecting an abnormal part (yam defect) of the yam Y. Near the yam
monitor 11, a cutter 12 configured to cut the yam Y immediately after
5 the yam monitor 11 has detected a yarn defect is provided.
[0030] When the yarn monitor 11 has detected a yam defect and cuts
the yam, or when the yam being unwound from the yam supplying
bobbin 6 breaks, for example, the splicer device 13 splices the lower
yam on the yam supplying bobbin 6 side and the upper yam on the side
10 of a winding bobbin 14. As the splicer device configured to splice the
upper yam and the lower yam, a mechanical knotter or a device using
fluid such as compressed air, for example, can be used.
[0031] Below the splicer device 13, a lower-yam catching member 16
configured to catch the lower yam to guide the lower yam to the splicer
15 device 13 is provided. Above the splicer device 13, an upper yam
catching member 18 configured to catch the upper yam to guide the
upper yam to the splicer device 13 is provided.
[0032] The winding section 15 includes a cradle 20 configured to
support the winding bobbin 14 around which the yam Y is wound and
20 the contact roller 22 configured to come into contact with the
circumferential surface of the winding bobbin 14 and being rotatable.
The winding section 15 includes a rotational driving source (not
depicted) configured to rotationally drive the winding bobbin 14
supported by the cradle 20. By rotationally driving the winding bobbin
25 14, the yam Y can be wound around the circumference of the winding
bobbin 14. The winding bobbin 14 around which the yam Y has been
6
FP16-0433-00
wound in this manner is called a package P.
[0033] The winder tmit 2 includes an arm-type traverse device 24
configured to traverse the yam Y to be wound around the winding
bobbin 14 near the cradle 20. As depicted in FIG. 3, the traverse
5 device 24 includes a traverse driving motor (driving section) 26 and a
traverse guide 30.
[0034] The traverse driving motor 26 is a driving source configured to
move the traverse guide 30 in a reciprocating rotational manner. The
traverse driving motor 26 is configured with a servo motor, for example.
10 The traverse driving motor 26 has a rotational drive shaft 28 connected
to the traverse guide 30 as an output shaft. The traverse guide 30 is
fixed to the rotational drive shaft 28 in a relatively non-rotatable
manner. As depicted in FIG 3, in a state in which the traverse guide
30 is fixed to the rotational drive shaft 28, the longitudinal direction of
15 the traverse guide 30 is substantially orthogonal to the rotational drive
shaft 28.
[0035] The rotor of the traverse driving motor 26 repeats forward and
reverse rotations, whereby the traverse guide 30 moves in a
reciprocating rotational manner. In a guide member 51 (described later
20 in detail) attached to the traverse guide 30, the yarl1 Y is caught.
Accordingly, this yam Y reciprocates in the winding width direction
(lateral direction in FIG. 2) of the package P in conjunction with the
motion of the traverse guide 30. By rotating the winding bobbin 14
while the yam Y is being guided by the guide member 51, the yam Y is
25 wound around the winding bobbin 14 while being traversed, whereby
the package P of a predetermined shape can be formed.
7
FP16-0433-00
[0036] The following describes the traverse guide 30 in detail. As
depicted in FIG. 4, the traverse guide 30 includes an arm body member
31 and an attached member 41 attached to the ann body member 31.
The following description is made assuming that the longitudinal
5 direction of the traverse guide 30 is a "direction a", the direction along
the traveling direction of the yam Y mihogonal to the direction a is a
"direction ~", and the crosswise direction of the traverse guide 30
orthogonal to the direction a and to the direction ~ is a "direction y".
The direction intersecting the direction ~ is any direction including the
10 direction a and the direction y.
[003 7] The arm body member 31 has a body portion 32, a base end
portion 33 provided to the body portion 32 on the base end side in the
direction a, and a distal end portion 34 provided to the body portion 32
on the distal end side in the direction a. · The arm body member 31
15 contains a metallic material. The arm body member 31 of the present
embodiment is molded by die casting, thixomolding, or injection
molding, for example, using the metallic material. The arm body
member 31 is molded integrally with the guide member 51 described
later without adhesive applied therebetween. The metallic material
20 herein is a material containing metal or an alloy. Examples of the
metallic material contained in the arm body member 31 include an
aluminium alloy, a magnesium alloy, brass, a zinc alloy, a beryllium
alloy, and zinc.
[0038] The body portion 32 has a shape of a plate that tapers down
25 from the base end portion 33 toward the distal end portion 34. The
base end portion 33 is a portion to which the attached member 41 is
8
attached. On the base end portion 33, through holes 33a, 33b, 33c, and
33d are formed. Into each of the through holes 33a, 33b, and 33c, a
fastener (not depicted) such as a screw is inserted. By screwing the
fasteners into the attached member 41 through the through holes 33a,
5 33b, and 33c, the attached member 41 is fastened to the base end
portion 33. Into the through hole 33d, the rotational drive shaft 28 (see
FIG. 3) is inserted.
[0039] The attached member 41 contains aluminium, for example.
The attached member 41 is fmmed by machining, for example. In the
10 attached member 41, an attachment hole 42 into which the rotational
drive shaft 28 (see FIG. 3) is inserted is formed. The traverse guide 30
is attached to the rotational drive shaft 28 (see FIG. 3) through the
attachment hole 42.
[0040] Referring to FIG. 4, FIG. 5A, FIG. 5B, and FIG. 6, the following
15 describes the distal end portion 34 and the guide member 51 that is
fixed integrally with the distal end portion 34 in detail.
[0041] As depicted in FIG. 5A, the distal end portion 34 has a hook-like
curved shape. Specifically, the distal end portion 34 extends straight
from the base end side along the direction a and is then curved, and the
20 distal end thereof extends so as to face the base end portion 33. The
distal end portion 34 bends in a hook-like shape to form a substantial
J-shape in plan view.
[0042] The guide member 51 is a portion that comes into contact with
the yam Yin the traverse guide 30. The guide member 51 has a yam
25 hooking portion 51 a configured to hook the yam Y. As depicted in
FIG. 5B, similarly to the distal end portion 34, the guide member 51 has
9
FP16-0433-00
a hook-like curved shape having a substantial J-shape in plan view.
Specifically, the guide member 51 extends straight from the base end
51 b thereof along the direction ~ and is then curved at a curved portion
51 f, and the distal end 51 c thereof extends so as to face the base end
5 portion 33. ln the guide member 51, the base end 51b is positioned
closer to the body portion 32 than the distal end 51c is. The guide
member 51 may be surface treated. In this case, on the guide member
51, a surface treatment film is provided. This surface treatment film
includes at least one of a diamond-like carbon film (DLC film), a
10 titanium nitride t1lm (TiN film), a titanium carbonitride film (TiCN
film), a titanium aluminium nitride film (TiAIN film), and an aluminium
chromium nitride film (AlCrN film).
[0043] The yam hooking portion 5la is structured with portions
including a side surface of the guide member 51 on the inner peripheral
15 side. The yam hooking portion 51a is disposed on a curved-shape
inner side than a side surface 34a of the distal end portion 34 on the
inner peripheral side is. The yam hooking portion 51a is provided
along the shape of the guide member 51, and bends in a hook-like shape
to form a substantial J-shape in plan view. The yam Y (see FIG 3)
20 traversed by the traverse device 24 slidingly travels while being in
contact with the yam hooldng portion 51 a. The term "ilmer periphery"
herein means a periphery of the curve bending in a hook-like shape on
the inner side. The tenn "curved-shape inner side" means the inner
side in the curved shape.
25 [0044] As depicted in FIG. 5B and FIG. 6, part of the guide member 51
other than the yam hooldng portion 51 a is embedded in the distal end
10
FP16-0433-00
pmtion 34 of the arm body member 31. Specifically, in a groove 34b
formed on the side surface 34a of the distal end portion 34 on the inner
peripheral side, an outer peripheral part 5ld of the guide member 51 is
embedded. In other words, the outer peripheral part 51 d is an
5 embedded portion embedded in the distal end portion 34. In the outer
peripheral part 51 d, a side surface on the outer peripheral side and a pair
of surfaces intersecting the direction p are covered by the groove 34b in
a state of being in close contact with the groove 34b without a gap
therebetween. In contrast, an inner peripheral part 51e of the guide
10 member 51 including the yam hooking portion 51 a is exposed from the
distal end pmtion 34. The inner peripheral part 51 e protrudes toward
the curved-shape inner side more than the side surface 34a of the distal
end portion 34 on the inner peripheral side does. The term "outer
periphery" herein means a periphery of the curve bending in a hook-like
15 shape on the outer side.
[0045] The distal end 51 c and its vicinity of the guide member 51 jut
out toward the body portion 32 more than the distal end 34c of the distal
end pmtion 34 does. With this configuration, the yarn Y to be
traversed can be made less likely to come into contact with the distal
20 end 34c of the distal end portion 34.
[0046] The guide member 51 thus configured is integrally fixed to the
distal end portion 34 of the ann body member 31. The guide member
51 is tucked into and engages with the ann body member 31 in the
direction B, and is also tucked into and engages with the arm body
25 member 31 in the direction intersecting the direction p. In other
words, the guide member 51 is tucked into and engages with the arm
11
FP16-0433-00
body member 31 in all of the direction a, the direction ~' and the
direction y as depicted in FIG. SA and FIG 5B.
[004 7] As described above, the hardness of the guide member 51 is
higher than the hardness of the arm body member 31. For example,
5 the hardness of material contained in the guide member 51 only needs to
be equal to or higher than 120HV in Vickers hardness. Specific
examples of the material contained in the guide member 51 include
ceramics such as alumina and zirconia, silicon nitride, silicon carbide,
and high-hardness alloy materials such as a tungsten alloy, a nickel
10 alloy, a chromium-molybdenum alloy, a nickel-chromium-molybdenum
alloy, and a chromium alloy. In the present embodiment, the guide
member 51 contains alumina.
[0048] The following describes one example of a method for producing
the traverse guide 30 with reference to FIG 7. As depicted in FIG. 7,
15 the guide member 51 containing alumina is prepared (step Sl). This
guide member 51 is formed in a hook-like shape by sintering using a
muffle furnace, for example. On the guide member 51, grinding, for
example, may be performed.
[0049] Subsequently, the metallic material and the guide member 51 are
20 placed in a die, and the die is closed. The metallic material in the die
is hot molded and is then cooled to fo11n the arm body member 31 (step
S2). At step S2, the metallic material and the guide member 51 are
placed in the die so that at least part of the guide member 51 other than
the yarn hooking portion 51 a is embedded in the metallic material.
25 When the arm body member 31 is molded from the metallic material in
the die, this placement allows the arm body member 31 and the guide
12
FP16-0433-00
member 51 to be integrated without adhesive applied therebetween. In
other words, the guide member 51 is fixed integrally with the arm body
member 31 when the arm body member 31 is molded.
[0050] At step 82, when the arm body member 31 is formed by
5 injection molding, the metallic material in a chip form or a pellet form
may be placed in the die. When the arm body member 31 containing
the metallic material is formed by injection molding, the melting
temperature of the metallic material is set lower, whereby dimensional
accuracy and strength, for example, of the arm body member 31 can be
1 0 improved.
[0051] Subsequently, the arm body member 31 in which the guide
member 51 is embedded is taken out of the die (step 83). After
grinding or other treatment is perfonned on the arm body member 31 if
necessary, the attached member 41 is attached to the ann body member
15 31 (step 84). At step 84, with screws to be inserted into the through
holes 33a, 33b, and 33c, the attached member 41 is fastened to the base
end portion 33. Through the above steps, the traverse guide 30 is
produced.
[0052] It should be noted that directly identifying the structure of the
20 traverse guide 30 may be impossible or unrealistic because the guide
member 51 is integrally fixed when the arm body member 31 is molded
as described above. In other words, there are circumstances in which
directly identifying all of the traverse guide 30 based on the structure or
characteristics thereof is impossible or unrealistic.
25 [0053] In the traverse guide 30, the winder unit 2 including the traverse
guide 30, and the method for producing the traverse guide 30 described
13
FP16-0433-00
above, at least part of the guide member 51 other than the yam hooking
portion 51 a has the embedded portion (outer peripheral part 51 d)
embedded in the distal end portion 34 of the arm body member 31.
With this configuration, the at least part of the guide member 51 other
5 than the yam hooking portion 5la enters and comes into close contact
with the distal end portion 34 of the arm body member 31, and is tucked
into the arm body member 31 so as not to detach. Consequently, the
guide member 51 is integrally fixed, being firmly held on the arm body
member 31 without adhesive applied therebetween so as not to detach.
10 Thus, without applying adhesive, the guide member 51 can be reliably
fixed to the arm body member 31.
[0054] Even if conditions for using the traverse guide 30 have changed,
strength of fixing the arm body member 31 to the guide member 51 is
less likely to decrease than the case that a guide member is fixed to an
15 ann body member by applying adhesive. Because the hardness of the
guide member 51 is higher than the hardness of the arm body member
31, abrasion resistance of the yarn hooking portion 51 a can be
improved. Thus, in the winder unit 2 including the above-described
traverse guide 30, the traverse guide 30 can traverse the yarn Y for a
20 long period of time.
[0055] The guide member 51 and the distal end portion 34 integrally
fixed to the guide member 51 each have a hook-like curved shape.
The yarn hooking portion 51 a is structured with portions including the
side surface of the guide member 51 on the inner peripheral side, and is
25 disposed on the curved-shape inner side than the side surface 34a of the
distal end portion 34 on the inner peripheral side is. With this
14
FP16-0433-00
configuration, the yam Y to be traversed can be reliably hooked on the
yam hooking portion 51 a, and the yam Y can be prevented from coming
into contact with portions other than the yam hooking portion 51 a.
[0056] The guide member 51 is tucked into and engages with the arm
5 body member 31 in the direction B, and also is tucked into and engages
with the arm body member 31 in the direction intersecting the direction
~· With this configuration, position error of the guide member 51 in
the direction ~ and the direction intersecting the direction ~ can be
prevented by the arm body member 31.
10 [0057] The guide member 51 is fixed integrally with the arm body
member 31 when the arm body member 31 is molded. In this case,
without applying adhesive, the guide member 51 can be firmly fixed to
the arm body member 31 .
[0058] The metallic material contained in the ann body member 31 is
15 an aluminium alloy, a magnesium alloy, brass, a zinc alloy, a beryllium
alloy, or zinc. This can reduce the weight of the traverse guide 30.
[0059] The guide member 51 contains ceramics. In this case, the
guide member 51 having high hardness can be prepared at low cost.
Herein, instead of ceramics, the guide member 51 may contain a
20 tungsten alloy, a nickel alloy, a chromium-molybdenum alloy, a
nickel-chromium-molybdenum alloy, or a chromium alloy. In this
case, the guide member 51 can contain a metallic material having high
hardness.
[0060] On a surface of the guide member 51, at least one of a
25 diamond-like carbon film, a titanium nitride film, a titanium
carbonitride film, a titanium aluminium nitride film, and an aluminium
15
FP16-0433-00
chromium nitride film may be provided. In this case, abrasion
resistance of the guide member 51 improves.
[0061] In the traverse guide 30 according to the above-described
embodiment, the guide member 51 and the distal end portion 34 may be
5 provided to the body portion 3 2 on the distal end side in a state of being
rotated 180° about the direction P from the state depicted in FIGS. 5A
and 5B. In other words, the guide member 51 and the distal end
portion 34 bending in hook-like shapes may be formed so that the
opening on the curved-shape inner side is open to the distal end side of
10 the arm body member 31, instead of being fonned as depicted in FIGS.
5A and 5B in which the opening on the curved-shape inner side is open
to the base end side of the arm body member 31. Specifically, the
guide member 51 may be integrally fixed to the distal end portion 34 by
forming the groove 34b (see FIG. 6) of the distal end portion 34 so that
15 the groove 34b is open to the distal end side, and embedding the outer
peripheral part 51d of the guide member 51 along the groove 34b.
[0062] In the method for producing the traverse guide 30 according to
the above-described embodiment, when the material contained in the
guide member 51 is ceramics, before step S2, an intermediate layer may
20 be provided on a surface (e.g., a side surface ofthe guide member 51 on
the outer peripheral side) of the guide member 51 embedded in the ann
body member 31. In other words, the traverse guide 30 may further
include an intennediate layer provided on a surface of the guide
member 51 embedded in the arm body member 31. The intermediate
25 layer is a layer having excellent accessibility (wettability) to the ann
body member 31 containing the metallic material. The intermediate
16
FP16-0433-00
layer is a metallization layer, for example. The metallization layer is
provided on the surface of the guide member ~ 1 hy metallizing wi.th
high-melting point metal paste, active-metal plating, or noble-metal
plating, for example. By providing such a metallization layer on the
5 surface, bondability between the arm body member 31 containing the
metallic material and the guide member 51 containing ceramics can be
improved. In addition, by chemical bonding (metal bonding) between
the metallic material of the ann body member 31 and the metallization
layer, without applying adhesive, the guide member 51 is firmly fixed to
10 the arm body member 31. If the guide member 51 is surface treated,
the metallization layer may be provided after the surface treatment film
is formed, or may be provided before the surface treatment film is
formed. In other words, the surface treatment film may be provided on
the metallization layer, or may be provided between the surface of the
15 arm body member 31 and the metallization layer.
[0063] Hereinafter, first to fourth modifications of the above-described
embodiment will be described. In the description of the first to fourth
modifications, points different from those in the above-described
embodiment will be mainly described.
20 [0064] The following describes the first modification. In the first
modification, as depicted in FIG. 8 and FIG. 9, a portion of a guide
member 51 A embedded in a distal end portion 34A is provided with a
pair of protruding portions 52. The protruding portions 52 are
provided extending along the outer peripheral part 51 d of the guide
25 member 51A. The protruding portions 52 protrude in the direction ~
from a pair of surfaces of the outer peripheral part 51 d each on the outer
17
FP16-0433-00
peripheral side. This guide member 51A has a substantial T-shape
cross section.
[0065] In the arm body member 31, recesses 35 in which the protruding
portions 52 are embedded in a state of being in close contact therewith
5 are formed. The recesses 3 5 have shapes corresponding to the
protruding portions 52 of the guide member 51 A. The recesses 35 are
formed extending along the groove 34b. The recesses 35 are formed in
a pair on the bottom side of the groove 34b so as to face each other in
the direction ~· The pair of the recesses 35 each are recessed on one
10 side and the other side in the direction ~·
[0066] In also the first modification described above, the guide member
51 A is integrally fixed to the ann body member 31, being frrmly held on
the arm body member 31 without adhesive applied therebetween so as
not to detach. Thus, the functional effect of enabling the guide
15 member 51A to be reliably fixed to the ann body member 31 without
applying adhesive can be obtained. Furthetmore, in the first
modification, the protruding portions 52 are engaged with the recesses
35 in the direction intersecting the direction ~' whereby the guide
member 51A can be reliably prevented from detaching. Because the
20 protruding portions 52 are in close contact with the recesses 35, a
backlash of the guide member 51 can be prevented.
[0067] In the above-described iirst modification, only either one of the
pair of the protruding portions 52 may be provided. The protruding
portions 52 do not necessarily have to be provided extending
25 continuously along the outer peripheral part 51 d of the guide member
51A, and may be provided extending intermittently, for example. The
18
FP16-0433-00
protruding portions 52 may be provided to the arm body member 31,
and the recesses 35 may be formed in the guide member 51 A. In also
these cases, the above-described functional effect can be obtained.
The essential thing is that either one of the portion of the guide member
5 51A embedded in the ann body member 31 and the arm body member
31 needs to be provided with the protruding portions 52, and the other
needs to be provided with the recesses 3 5.
[0068] The following describes the second modification. In the
second modification, as depicted in FIG. lOA, FIG. lOB, and FIG. llA,
10 in a guide member 51B, part of the outer peripheral part 5lg juts out
toward the curved-shape outer side more than a distal end portion 34B
does, and part of the inner peripheral part 51 e juts out toward the
curved-shape inner side more than the distal end portion 34B does.
Specifically, areas from the vicinity of the curved portion 51 f to a distal
15 end part in the outer peripheral part 5lg of the guide member 51B are
exposed from the distal end portion 34B. In the same manner, areas
from the distal end 51 c to the vicinity of the base end 51 b in the inner
peripheral part 5le of the guide member 51B are exposed from the
distal end portion 34B. In contrast, areas other than the
20 above-described exposed areas in the guide member 51B are embedded
in the distal end portion 34B. In other words, areas other than the
exposed areas in the guide member 51B are embedded portions
embedded in the distal end portion 34B.
[0069] In the guide member SIB, through holes 53a to 53c are formed
25 each along the direction ~. The shape of the through holes 53 a to 53c
in plan view is circular, but may be substantially rectangular, for
19
FP16-0433-00
example. The through holes 53a to 53c are formed in the guide
member 51B at portions embedded in the distal end portion 34B. The
through holes 53 a to 53c are separated from each other. As depicted in
FIG. 1 OB, the through hole 53 a is formed on the base end 51 b side with
5 respect to the curved portion 51f of the guide member 51B. The
through hole 53b is formed near the curved portion 51f of the guide
member 51B. The through hole 53c is formed on the distal end 5lc
side with respect to the curved portion 51f of the guide member 51B.
The number of through holes fom1ed in the guide member 51B may be
10 one or two, or may be four or more. When a plurality of through holes
are formed in the guide member 51B, at least one thereof needs to be
formed on the base end 51 b side with respect to the curved portion 51 f
of the guide member 51B, and at least one of the others needs to be
fonned on the distal end 51 c side with respect to the curved portion 51f
15 of the guide member 51B.
[0070] The distal end portion 34B includes a pair of plate-like portions
34d between which the guide member 51B is sandwiched along the
direction ~ and bone portions 36a to 36c (first bone portion) extending
along the direction p. The pair of the plate-like portions 34d are
20 coupled to each other by the bone portions 36a to 36c. The number of
bone portions provided to the distal end portion 34B is the same as the
number of the through holes. The bone portion 36a is inserted into the
through hole 53 a and is in close contact with the inner surface of the
through hole 53a. In the same manner, the bone portion 36b is insetted
25 into the through hole 53b and is in close contact with the inner surface
of the through hole 53b, and the bone portion 36c is inserted into the
20
FP16·0433 .. 00
through hole 53c and is in close contact with the inner surface of the
through hole 53c. Thus, the shapes of the bone portions 36a to 36c are
the same as the shapes ofthe through holes 53a to 53c, respectively.
[0071] In also the second modification described above, the guide
5 member 51B is integrally fixed to the arm body member 31, being
firmly held on the arm body member 31 without adhesive applied
therebetween so as not to detach. Thus, the functional effect of
enabling the guide member 51B to be reliably fixed to the arm body
member 31 without applying adhesive can be obtained.
10 [0072] Furthermore, in the second modification, guide member 51B is
engaged with the arm body member 31 in the direction intersecting the
direction ~ by the through holes 53 a to 53c and the bone portions 36a to
36c. Thus, the guide member SIB can be reliably prevented from
detaching. Because the bone p01iions 36a to 36c are in close contact
15 with the inner surfaces of the through holes 53 a to 53c, respectively, a
backlash of the guide member 51B can be prevented.
[0073] In the second modification, as depicted in FIG. lOB, the base
end 5lb of the guide member 51B is embedded in the distal end portion
34B of the arm body member 31. In this case, a gap or a level
20 difference, for example, formed between the base end 51 b of the guide
member 51B and the arm body member 31 can be bridged. With this
configuration, the yam Y to be traversed can be prevented from being
caught in the gap or the level difference, for example.
[0074] Alternatively, as depicted in FIG. llB, instead of the bone
25 portions 36a to 36c (see FIG. llA), protruding portions 37a to 37d may
be provided to the distal end portion 34C. The protruding portions 37a
21
FP16-0433-00
to 37d each protrude toward the guide member 51C along the direction
~. The distal end of the protruding portion 37a and the distal end of
the protruding portion 3 7b face each other with a gap interposed
therebetween in the direction ~. The distal end of the protmding
5 portion 3 7 c and the distal end of the protruding portion 3 7 d face each
other with a gap interposed therebetween in the direction ~. In the
guide member 51 C, recesses 54a to 54d in which the protruding
portions 37a to 37d are embedded, respectively, in a state of being in
close contact therewith are formed.
10 [0075] Altematively, for example, a plurality of dimples (recesses) may
be formed in the guide member 51 C, and a plurality of protruding
portions that are embedded in the respective dimples in a state of being
in close contact therewith may be provided to the distal end portion
34C. Furthermore, for example, the distal end of the protruding
15 portion 3 7 a and the distal end of the protruding portion 3 7b may be in
contact with each other. In the same manner, the distal end of the
protmding portion 37c and the distal end of the protruding pmiion 37d
may be in contact with each other.
[0076] The following describes the third modification. In the third
20 modification, as depicted in FIG. 12A and FIG. 12B, a guide member
51D has a first member 61 and a second member 62. The first member
61 and the second member 62 are members having stick shapes each
extending along the direction a. The first member 61 and the second
member 62 are separated from each other in parallel. The length of the
25 first member 61 along the direction a is longer than the length of the
second member 62. The stick shape is also called a column shape.
22
FP16-0433-00
The first member 61 and the second member 62 may have a cylindrical
column shape or may have a polygonal column shape. The first
member 61 and the second member 62 of the third modification are
members having cylindrical column shapes.
5 [0077] Pmt of the first member 61 is embedded in a distal end portion
34D. Specifically, both end portions of the first member 61 are
embedded in the distal end portion 34 D. A portion of the first member
61 on the side opposite to the second member 62 side is embedded in
the distal end portion 34D. In other words, both end portions of the
10 first member 61 and the portion of the first member 61 on the side
opposite to the second member 62 side are embedded portions
embedded in the distal end portion 34D. In contrast, a portion of the
first member 61 other than these portions is exposed from the distal end
portion 34D.
15 [0078] Part of the second member 62 is embedded in the distal end
pmtion 34D. Specifically, both end portions of the second member 62
are embedded in the distal end pmtion 34D. A portion of the second
member 62 on the side opposite to the first member 61 side is embedded
in the distal end portion 34D. In other words, both end portions of the
20 second member 62 and the portion of the second member 62 on the side
opposite to the first member 61 side are embedded portions embedded
in the distal end portion 34D. In contrast, a portion of the second
member 62 other than these pmtions is exposed from the distal end
portion 34D.
25 [0079] The exposed portion of the first member 61, which is a portion
of the first member 61 excluding both end portions and including a
23
FP16-0433-00
surface opposing to the second member 62, fom1s a yarn hooking
portion 61a. The exposed portion of the second member 62, which is a
portion of the second member 62 excluding both end portions and
including a surface opposing to the first member 61, forms a yarn
5 hooking portion 62a. The yam hooking portions 61a and 62a have the
same function as that of the yarn hooking portion 51a in the
above-described embodiment. These yarn hooking portions 61 a and
62a are disposed on the curved-shape inner side than the side surface
34a of the distal end portion 34D on the inner peripheral side.
10 [0080] Herein, the distal end 34c of the distal end portion 34D
protrudes toward a curved direction inner side (first member 61 side) in
the direction y. With this configuration, the end portion of the second
member 62 is securely embedded in the distal end portion 34D.
[0081] In also the third modification described above, the guide
15 member 51D is integrally fixed to the arm body member 31, being
firmly held thereon without adhesive applied therebetween so as not to
detach. Thus, the functional effect of enabling the guide member 51D
to be reliably fixed to the arm body member 31 without applying
adhesive can be obtained. Furthermore, in the third modification,
20 because the first member 61 and the second member 62 are simple
members having stick shapes, the guide member 51D can be easily
formed. Because both ends of each of the first member 61 and the
second member 62 are embedded in the distal end portion 34D, these
both ends of each of the first member 61 and the second member 62 can
25 reliably prevent the guide member 51D from detaching.
[0082] The following describes the fourth modification. In the fourth
24
FP16-0433-00
modification, as depicted in FIG. 13A, FIG. 13B, and FIG. 14, a guide
member 51E covers most part of the distal end portion 34E in the arm
body member 31. Specifically, the guide member 51E covers at least
the side surface 34a of the distal end portion 34E on the inner peripheral
5 side and a pair of surfaces of the distal end portion 34E that intersect the
direction p. In contrast, the side surface of the distal end portion 34E
on the outer peripheral side is not covered by the guide member 51 E.
[0083) In the distal end potiion 34E, through holes 38a and 38b are
formed along the direction p. The shape of the through holes 38a and
1 0 3 8b in plan view is circular, but may be substantially rectangular, for
example. The through holes 38a and 38b are formed in the distal end
portion 34E at portions covered by the guide member 51E, and are
separated from each other. As depicted in FIG 13B, the through hole
38a is formed in the distal end pmiion 34E on the base end side with
15 respect to a curved pmiion 34e. The through hole 38b is formed in the
distal end portion 34E on the distal end side with respect to the curved
portion 34e. In the fourth modification, when a plurality of through
holes are fonned in the distal end portion 34E, at least one of the
through holes needs to be formed in the distal end pmiion 34E on the
20 distal end side with respect to the curved portion 34e, and at least one of
the other through holes needs to be formed in the distal end portion 34E
on the base end side with respect to the curved portion 34e.
[0084] The guide member 51E is provided with bone portions 55a and
55b (second bone pmiion) extending along the direction p. The
25 number of bone portions provided to the guide member 51E is the same
as the number of the through holes. The bone portion 55 a is inserted
25
FP 16-043 3-00
into the through hole 38a and is in close contact with the inner surface
of the through hole 38a. In the same manner, the bone portion 55b is
inserted into the through hole 38b and is in close contact with the inner
surface of the through hole 38b. Thus, the shapes of the bone portions
5 55a and 55b are the same as the shapes of the through holes 38a and
38b, respectively. The bone portions 55a and 55b are embedded
portions embedded in the distal end portion 34E ..
[0085] In also the fourth modification described above, the guide
member 51E is integrally fixed to the arm body member 31, being
10 firmly held thereon without a gap interposed therebetween and without
adhesive applied therebetween so as not to detach. Thus, the
functional effect of enabling the guide member 51 E to be firmly fixed to
the ann body member 31 without applying adhesive can be obtained.
Furthermore, in the fourth modification, the guide member 51 E is
15 engaged with the ann body member 31 in the direction intersecting the
direction~ by the through holes 38a and 38b and the bone portions 55a
and 55b. Thus, the guide member 51E can be reliably prevented from
detaching. Because the bone portions 55a and 55b are in close contact
with the inner surfaces of the through holes 38a and 38b, respectively, a
20 backlash of the guide member 51E can be prevented.
[0086] In the foregoing, the embodiment according to the present
disclosure and the modifications thereof have been described, but the
present disclosure is not limited to the above-described embodiment and
the above-described modifications. The present disclosure may be
25 modified within a scope not altering the gist described in each claim.
The above-described embodiment and the above-described
26
FP16-0433-00
modifications may be used in combination as appropriate.
[0087] For example, the base end 51 b of the guide member 51 in the
above-described embodiment may be embedded in the arm body
member 31 as described in the second modification (the base end 51 b
5 may be included as an embedded portion). In this case, also in the
above-described embodiment, in the same manner as in the second
modification, the yam Y to be traversed can be prevented from being
caught in a gap or a level difference, for example, formed between the
base end 51 b of the guide member 51 and the ann body member 31.
10 In the same manner, also in the fomth modification, the base end of the
guide member 51E may be embedded in the arm body member 31 (the
base end of the guide member 51E may be included as an embedded
portion).
[0088] In the above-descdbed embodiment and the above-described
15 modifications, the arm body member 31 contains the metallic material,
but the present disclosure is not limited to this. For example, the arm
body member 31 may contain metal oxide or resin. The arm body
member 31 may be a component having the body portion 32 the length
of which is very short in the direction a. Alternatively, the arm body
20 member 31 may be a relatively small component that does not have the
body portion 32 and in which the base end pmtion 33 and the distal end
portion 34 are integrated. In this case, the arm body member 31 may
be attached to a member configured to traverse, such as a belt. The
essential thing is that the arm body member 31 only needs to be a
25 member integrally fixing the guide member, and does not necessarily
have to be a member in itself configured to traverse.
27
FP16-0433-00
[0089] At least some parts of the embodiment and the modifications
described above may be optionally used in combination.
[0090] A traverse guide includes: an ann. body member having a distal
end portion in a hook-like curved shape and containing a metallic
5 material; and a guide member integrally fixed to the distal end portion
of the arm body member and having a yarn hooking portion configured
to hook a yam. Hardness of the guide member is higher than hardness
of the ann body member, and in at least part of the guide member other
than the yam hooking portion, an embedded portion to be embedded in
10 the distal end portion is fonned.
[0091] In the traverse guide, the guide member may be fixed integrally
with the arm body member when the ann body member is molded. In
this case, without applying adhesive, the guide member can be firmly
fixed to the arm body member.
15 [0092] The traverse guide may include: an ann body member having a
distal end portion in a hook-like curved shape and containing a metallic
material; and a guide member integrally fixed to the distal end portion
of the arm body member and having a yarn hooking portion configured
to hook a yarn. In at least part of the guide member other than the yam
20 hooking portion, an embedded portion to be embedded in the distal end
portion may be fonned. In this case, without applying adhesive, the
guide member can be reliably fixed to the ann body member.
[0093] The traverse guide may include: an arm body member having a
distal end portion in a hook-like curved shape and containing a metallic
25 material; and a guide member integrally fixed to the distal end portion
of the ann body member and having a yam hooking portion configured
28
FP16-0433-00
to hook a yarn. A lhruugh hole may be fo11ned in the guide member,
and the arm body member may have a first bone portion inserted into
the through hole and being in close contact with an inner surface of the
through hole. In this case, the through hole and the first bone portion
5 can prevent the guide member from detaching. Because the first bone
portion is in close contact with the inner surface of the through hole, a
backlash of the guide member can be prevented.
[0094] The traverse guide may include: an arm body member having a
distal end portion in a hook-like curved shape and containing a metallic
10 material; and a guide member integrally fixed to the distal end portion
of the arm body member and having a yam hooking portion configured
to hook a yam. The guide member may be tucked into and engage
with the arm body member along a traveling direction of the yam, and
may also be tucked into and engage with the arm body member along a
15 direction intersecting the traveling direction. In this case, the arm
body member can prevent position error of the guide member in the
traveling direction and the direction intersecting the traveling direction.
[0095] The traverse guide may include: an arm body member having a
distal end portion in a hook-like curved shape and containing a metallic
20 material; and a guide member integrally fixed to the distal end portion
of the arm body member and having a yam hooking portion configured
to hook a yarn. The guide member may be provided so as to cover
part of the arm body member, a through hole may be formed in the ann
body member, and the guide member may have a second bone portion
25 inserted into the through hole and being in close contact with an inner
surface of the through hole. In this case, the through hole and the
29
FP16-0433-00
second bone portion can prevent the guide member from detaching.
Because the second bone portion is in close contact with the inner
surface of the through hole, a backlash of the guide member can be
prevented.
5 [0096] The traverse guide may include: an arm body member having a
distal end portion in a hook-like curved shape and containing a metallic
material; and. a guide member integrally fixed to the distal end portion
of the arm body member and having a yam hooking portion configured
to hook a yarn. The guide member may have a hook-like curved shape,
10 and the yam hooking portion may be structured with a portion including
an inner peripheral surface of the guide member and may be disposed
on a curved-shape inner side than an inner peripheral surface of the
distal end portion is. In this case, the yam to be traversed can be
prevented from coming into contact with portions other than the yarn
15 hooking portion.
[0097] In this traverse guide, at least part of the guide member other
than the yarn hooking portion has the embedded portion embedded in
the distal end portion of the arm body member. With this
configuration, the guide member is integrally fixed to the distal end
20 portion of the arm body member, being firmly held on the arm body
member without adhesive applied therebetween so as not to detach.
Thus, without applying adhesive, the guide member can be reliably
fixed to the ann body member.
[0098] In the traverse guide according to one aspect of the present
25 disclosure, a through hole may be fonned in the guide member, and the
arm body member may have a first bone portion inserted into the
30
FP16-0433-00
through hole and being in close contact with an im1er surface of the
through hole. In this case, the tln·ough hole and the first bone portion
can prevent the guide member from detaching. Because the first bone
portion is in close contact with the inner surface of the through hole, a
5 backlash of the guide member can be prevented.
[0099] In the traverse guide according to one aspect of the present
disclosure, the guide member may be tucked into and engage with the
arm body member along a traveling direction of the yam, and may also
be tucked into and engage with the arm body member along a direction
1 0 intersecting the traveling direction. In this case, the arm body member
can prevent position enor of the guide member in the traveling direction
and the direction intersecting the traveling direction.
[0 1 00] In the traverse guide according to one aspect of the present
disclosure, the guide member may be provided so as to cover part of the
15 arm body member, a through hole may be fonned in the arm body
member, and the guide member may have a second bone portion
inserted into the through hole and being in close contact with an inner
surface of the through hole. In this case, the through hole and the
second bone portion can prevent the guide member from detaching.
20 Because the second bone portion is in close contact with the inner
surface of the through hole, a backlash of the guide member can be
prevented.
[0 101] In the traverse guide according to one aspect of the present
disclosure, a protruding portion may be provided on either one of the at
25 least part of the guide member embedded in the ann body member and
the arm body member, and a recess with which the protruding portion is
31
FP16-0433-00
in close contact may be formed on the other one of the at least part of
the guide member embedded in the arm body member and the arm body
member. In this case, the protruding portion and the recess prevent the
guide member from detaching. Because the protruding portion is in
5 close contact with the recess, a backlash of the guide member can be
prevented.
[0102] In the traverse guide according to one aspect of the present
disclosure, the protruding portion may protrude along the traveling
direction of the yam. In this case, in the direction intersecting the
1 0 traveling direction of the yam, by engaging the protruding portion with
the recess, the guide member can be prevented from detaching.
[0103] In the traverse guide according to one aspect of the present
disclosure, the guide member may have a hook-like curved shape, and
the yarn hooking portion may be structured with a portion including an
15 hmer peripheral surface of the guide member and may be disposed on a
curved-shape inner side than an inner peripheral surface of the distal
end portion is. In this case, the yam to be traversed can be prevented
from coming into contact with portions other than the yarn hooking
portion.
20 [0104] In the traverse guide according to one aspect of the present
disclosure, a base end of the guide member may be embedded in the
arm body member. In this case, a gap or a level difference, for
example, formed between the base end of the guide member and the
am1 body member can be bridged. With this configuration, the yam to
25 be traversed can be prevented from being caught in the gap or the level
difference, for example.
32
FP16-0433-00
l 01 05j ln the traverse guide according to one aspect of the present
disclosure, the guide member may have a first member and a second
member that have stick shapes separated from each other in parallel, and
both ends of the first member and both ends of the second member may
5 be embedded in the arm body member. In this case, the first member
and the second member of the guide member can be easily formed. In
addition, both ends of the first member and the second member
embedded in the arm body member can prevent the guide member from
detaching.
10 [0 1 06] In the traverse guide according to one aspect of the present
disclosure, the metallic material may be an aluminium alloy, a
magnesium alloy, brass, a zinc alloy, a beryllium alloy, or zinc. This
can reduce the weight of the traverse guide.
[0 1 07] In the traverse guide according to one aspect of the present
1 5 disclosure, the guide member may contain ceramics. In this case, the
guide member having high hardness can be prepared at low cost.
[0 1 08] The traverse guide according to one aspect of the present
disclosure may further include an intermediate layer provided on a
surface of the guide member embedded in the arm body member. In
20 this case, the intermediate layer can improve bondability between the
arm body member and the guide member.
[0 1 09] In the traverse guide according to one aspect of the present
disclosure, the guide member may contain a tungsten alloy, a nickel
alloy, a chromium-molybdenum alloy, a nickel-chromium-molybdenum
25 alloy, or a chromium alloy. In this case, the guide member can contain
a metallic material having high hardness.
33
FP16-0433-00
[0110] In the traverse guide according to one aspect of the present
disclosure, on a surface of the guide member, at least one of a
diamond-like carbon film, a titanium nitride film, a titanium
carbonitride film, a titanium aluminium nitride film, and an aluminium
5 chromium nitride film may be provided. In this case, abrasion
resistance of the guide member improves.
[0111] A yam winding machine according to one aspect of the present
disclosure includes: the traverse guide described in any one of the above
paragraphs; a drive section configured to move the traverse guide in a
