Description
BACKGROUND
1. Field
[0001] The present disclosure relates apparatus used in winding
coils of filamentary material. More particularly, this disclosure
relates to filamentary material guides for guiding filamentary
material as it is being wound into a coil of filamentary
material.
2. State of the Art
[0002] U.S. Pat. No. 9,731,931 describes a REELEX-type winding
system 100 shown in FIG. 1. The system 100 directs filamentary
material 110 (e.g., wire) to a traverse 164, shown in greater
detail in FIG. 2, which shows a perspective view of the traverse
164 and a mandrel 170 of a take-up unit 116 of system 100. The
traverse moves back and forth above the surface of the mandrel 170
as the mandrel 170 is spinning on the spindle 166, thereby causing
wire 110 to be directed onto the mandrel 170. The function of the
entire system 100 is to cause wire 110 to be wound in a
figure-eight pattern in a manner forming a payout hole extending
radially out from the mandrel 170. The controller 118 is coupled to
the take-up system 116 and can provide speed control information to
direct the take-up system 116 to run at a desired rate. For
example, the controller 118 may direct the take-up system 116 to
cause the spindle 166 to run at a constant speed, or may cause the
take-up system 116 to have the line speed be constant, thereby
requiring the spindle speed to slow down over a period of time.
[0003] The traverse 164 is formed as a cantilevered beam 164a
having a longitudinal slot (not shown) through which a guide tube
164b extends. Guide tube 164b terminates in a wire guide 164c which
is located closest to the mandrel 170. The wire 110 is threaded
through the guide tube 164b and exits the wire guide 164c. The
guide tube 164b travels in (i.e., reciprocates in) the longitudinal
slot of the beam 164 a at desired speeds and along desired
distances as controlled by the take-up system 116 as optionally
informed by the controller 118 in order to form the figure-eight
pattern in a manner forming a payout hole.
[0004] In winding a figure-eight coil of wire, an end of the wire
110 is captured by the mandrel 170, and the mandrel is spun by the
spindle 166 as the traverse 164 reciprocates and guides the wire
onto the mandrel in a figure-eight pattern with a payout hole.
SUMMARY
[0005] In order to form a well-formed coil the wire must be laid
down with precision as the traverse reciprocates and as the mandrel
rotates. The position of the traverse is controlled to precisely
place wire leaving the wire guide 164c at predefined positions at
predefined times. However, if the wire passing through the wire
guide 164c is free to move laterally (i.e., horizontally) relative
to the wire guide 164c, the location at which the wire is actually
being laid down may not be at the intended location, resulting in a
coil that is not as well-formed as it could be. To improve the
formation of the coil, an adjustable filamentary guide apparatus
(i.e., a wire guide) is described herein that can limit the
relative lateral movement between the apparatus and the filamentary
material being dispensed from the apparatus.
[0006] According to one aspect, further details of which are
described herein, an adjustable filamentary material guide
apparatus for guiding filamentary material from a reciprocating
traverse onto a mandrel of a winding machine to form a coil
includes a housing having a collar defining an inlet opening
configured to receive filamentary material (e.g., from a cable
guide), adjustable guides coupled to the housing defining a guide
opening between the adjustable guides for passage of the
filamentary material, and an adjuster configured to adjust relative
spacing between the adjustable guides. A user can adjust the size
of the guide opening to closely match the size (e.g., diameter) of
the filamentary material being wound to reduce the amount of
relative lateral movement of the filamentary being dispensed from
the guide apparatus.
[0007] In embodiments, the inlet opening axially aligns in a
vertical direction with the guide opening. In embodiments, the
adjustable guides are configured to simultaneously move toward or
away from one another by operation of the adjuster. In embodiments,
the adjustable guides include rollers.
[0008] In embodiments, the adjustable guides extend along parallel
axes that lie in a horizontal plane that is perpendicular to a
vertical path for filamentary material that extends axially between
the inlet opening and the guide opening.
[0009] In embodiments, the adjuster includes a threaded adjuster
screw extending through aligned threaded bores formed in the
adjustable guides. The threaded adjuster screw extends along a
screw axis and the adjustable guides are configured to translate
(e.g., simultaneously) either toward or away from one another along
the screw axis depending on a direction of rotation of the screw
about the screw axis.
[0010] In embodiments, the adjustable guide apparatus further
includes non-adjustable guides that are coupled to the housing in
fixed spaced relation to one another and that extend along
respective axes that are perpendicular to the axes of the
adjustable guides. The adjuster guides are disposed vertically
between the non-adjustable guides and the collar of the
housing.
[0011] In embodiments, the collar is configured for coupling to a
reciprocating traverse that is operable to reciprocate the
adjustable guide apparatus as filamentary material is drawn through
the guide opening onto a mandrel of a winding machine.
[0012] In embodiments, the adjustable guide apparatus further
includes an adjustment ring having a neck threadably coupled to the
collar of the housing. The neck has an annular bearing surface on a
bottom side of the neck. The adjuster includes a pair of opposed
arms pivotally coupled to the housing at an intermediate location
along the length of each arm. Each arm has an upper portion and a
lower portion. The upper portion extends from the intermediate
location to a cam surface configured to bear against the annular
bearing surface of the neck. The lower portion is pivotally coupled
to one of the adjustable guides. Threading the adjustment ring
relative to the collar adjusts the position of the cam surfaces
along the annular bearing surface, and, thus adjusts the angular
position of the lower portion about the intermediate position,
which in turn, adjusts the relative spacing between the adjustable
guides for passage of the filamentary material therebetween.
[0013] In embodiments, the adjustable guide apparatus further
includes biasing members. Each biasing member is coupled between
the housing and respective lower portion. The biasing members are
configured to urge the opposed arms and the adjustable guides in a
direction towards one another. The biasing members may be
springs.
[0014] In embodiments, interference between the cam surfaces and
the annular bearing surface inhibit movement of the adjustable
guides towards each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] FIGS. 3 to 5 show aspects of an embodiment of an adjustable
guide apparatus 200 that can be used in place of guide 164c of
prior art FIG. 2. The wire guide includes a housing 202, a pair of
adjustable rollers 204, a threaded adjustment screw 206 for
adjusting the relative spacing between the rollers 204 along the
screw 206, an adjustment roller track 208 for supporting and
guiding the adjustable rollers 204, and a pair of guides 210. The
rollers 204 extend along respective axes A-A and B-B (FIG. 4) and
are axisymmetric. Specifically, the rollers 204 have a generally
symmetrical concave profile along their respective axes A-A and
B-B. The opposed concave profiles of the rollers defines an opening
201 between the rollers 204 through which filamentary material is
received from an opening 203 in the housing (in communication with
the guide tube 164b). The opening 201 may be centered with the
opening 203 along a central longitudinal axis G-G (FIG. 5)
extending through the apparatus 200. The width of the opening 201
is adjustable to account for different thickness (e.g., diameters)
of filamentary material. Specifically, the wire guide 200 includes
an arrangement that is configured to adjust the relative spacing
between the rollers 204 to adjust the size of the opening 201. The
guides 210 have a fixed spacing between them. The guides 210 are
configured to further guide filamentary material passing from the
opening 201 towards the mandrel 170.
[0028] The rollers 204, the screw 206, the track 208, and the
guides 210 are coupled to the housing 202. In the specific
embodiment shown in FIGS. 3 to 5, the screw 206 is coupled to the
housing 202 at holes 202c formed in the housing 200. The screw 206
and the track 208 extend along respective parallel axes C-C and
D-D. The track 208 has ends 208a (FIG. 5) that fixedly couple to
the housing 202 at holes 202b formed in the housing 200. The guides
210 have ends 210a (FIG. 5) that fixedly couple to the housing 202
at holes 202a formed in the housing 200. Each guide 210 may have a
roller 210b between the ends 210a that is configured to rotate
about a respective longitudinal axis E-E and F-F (FIG. 5), although
this is not a requirement.
[0029] In the embodiment shown, the rollers 204 are free to rotate
about respective axes A-A and B-B, which are which are transverse
to axes C-C, D-D, E-E, and F-F. Each roller 204 has a central
elongated shaft 204a (FIG. 5) having a first through bore 204b
(FIG. 4) at a first end for coupling to the track 208 and has a
second through bore 204c (FIG. 4) at a second, opposite end for
coupling to the screw 206. The first through bore 204b of each
roller 204 is aligned with axis D-D so that track 208 extends
through through bores 204b of both shafts 204a. The first through
bore 204b is configured for relative sliding movement with the
track 208. The second through bore 204c is female threaded and is
aligned with axis C-C for mating with male threads of the screw
206. The screw 206 threads with and extends through the through
bores 204c of both shafts 204a.
[0030] In the embodiment shown, the screw 206 is configured as an
adjuster screw with at least one head 206a and left hand threads
206b on one half (e.g., left half in FIG. 4) of the screw and right
hand threads 206c on the other half (e.g., right half in FIG. 4) of
the screw 206. Due to the thread configuration of the screw 206, a
rotation of the head 206a of the screw 206 in one rotational
direction about screw axis C-C will cause both of the rollers 204
to either simultaneously move toward or away from one another along
screw 206 and track 208. Thus, in operation, a user can adjust the
width of opening 201 between the rollers 204 by rotating the head
206a of the screw 206 about its axis C-C either clockwise or
counter-clockwise. In this manner, a user can set a specific
spacing between the rollers 204 that more closely matches the
diameter of the filamentary material passing through the apparatus
200, which can result in a coil that is more well-formed as
compared to an a spacing of the rollers 204 that does not closely
match the diameter of the filamentary material. As an alternative,
instead of a single adjuster screw 206, two screws having opposite
pitch threads may be used.
[0031] The apparatus 200 is adjustable and can be set by a user for
filamentary material of different thicknesses (i.e., diameter).
FIGS. 6 to 8 show various steps of a workflow of adjusting the
apparatus 200 for a filamentary material of a specific thickness.
If the rollers 204 are close together, a user turns the head 206a
of the adjustment screw 206 in a first rotational direction to
spread the rollers 204 sufficiently apart as shown in FIG. 6 to
permit a filament 250 to easily enter the opening 201. A user can
use any tool made for the screw head 206a, such as, for example, an
Allen wrench or flat head screwdriver. In the position of rollers
204 shown in FIG. 6, the opening 201 is wide enough so that the
filament 250 can fit in opening 201 without touching either roller
204. Next, a user rotates the head 206a of the screw 206 in a
second rotational direction, opposite the first direction, to close
the rollers 204 so that both rollers 204 contact (e.g., gently
squeeze) the filament 250 in the opening 201, as shown in FIG. 7.
Then, a user rotates the head 206a of the screw back in the first
rotational direction (e.g., one or two rotations) to back the
rollers 204 off the filament 250 and widen the opening 201 so that
the filament 250 contacts only one or the other of the rollers 204,
but does not contact both rollers 204, as shown in FIG. 8.
[0032] FIGS. 9A to 12 show aspects of another embodiment of an
adjustable guide apparatus 300. The guide apparatus 300 has a
housing 302 with a collar 302a that defines an opening 303 (FIGS.
9C, 12), which is configured to communicates with the guide tube
164b. The housing 302 houses an arrangement of adjustable guides
304 and guides 310 that define an opening 301 (FIGS. 9C, 10B, 12)
through which filamentary material is guided between the guide tube
164b and the mandrel 170. The opening 301 aligns with the opening
303 along central longitudinal axis H-H (FIG. 12) that extends
through the center of the guide apparatus 300.
[0033] The adjustable guides 304 and guides 310 may be roller
guides that extend along respective longitudinal axes. The
longitudinal axes of guides 304 and 310 may be perpendicular to one
another, as shown in FIGS. 9A and 9B. The guides 310 are supported
by plates 330 that are connected to the left and right sides of the
housing 302. Specifically, as shown in FIG. 11, each guide 310 may
have a shaft 310a surrounded by a roller 310b that can rotate about
the shaft 310a. The ends of the shaft 310a are configured to be
received in holes 330a formed in the plates 330. The guides 310 may
be disposed by the plates 330 below the rollers 304, as shown most
clearly in FIG. 10B. When the guides 310 are connected to the
plates 330, the spacing between the guides 310 remains fixed.
[0034] The guide apparatus 300 also includes an adjustment ring 320
that couples to the rim 302a of the housing 302. In the embodiment
shown in FIGS. 9A to 12, the ring 320 has a neck 322 having male
threads 322a that are configured to mate with female threads on the
inside surface of the collar 302a of the housing 302. The
adjustment ring 320 is coaxial with the housing 302 along axis H-H.
The adjustment ring 320 defines an internal open bore 305 (FIG. 12)
in communication with the collar 302a. The neck 322 extends
downward to an annular bearing surface 322b or rim on the bottom
side of the neck 322. The annular bearing surface 322b is
configured to bear against cam surfaces 324c of arms 324.
[0035] Each arm 324 defines a hole 324d (FIGS. 11 and 12) that
receives a pin 326 that pivotally couples the arm 324 to the
housing 302. The hole 324d is at an intermediate location between
an upper and a lower end of the arm 324. Each arm 324 has an upper
portion 324a between the hole 324d and the cam surface 324c, and a
lower portion 324b between the hole 324d and the roller 304. The
upper and lower portion 324a and 324b do not extend parallel to
each other. Instead, in the embodiment shown in FIG. 12, the upper
portion 324b is angled inwardly toward central axis H-H. Thus, when
vertically directed forces are exerted on the cam surfaces 324c
from the annular bearing surface 322b (such as by threading the
ring 320 into the collar 302a), the forces will exert a torque on
the arms 324 about pivotal connection at intermediate position 326
tending to spread the lower portions 324b apart (i.e., away from
axis H-H), thereby increasing the size of opening 301.
[0036] Once the annular bearing surface 322b is set to a specific
axial position relative to the collar 302a, the interference
between the cam surfaces 324c and the annular bearing surface 322b
sets a certain spacing between the opening 301 between the rollers
304. The interference prevents the opening 301 from decreasing.
Thus, the set initial size of the opening 301 can be considered a
minimum size of the opening 301. However, even after the ring 320
is set into position, the interference between cam surfaces 324c
and annular bearing surface 322b does not prevent the arms 324 from
rotating about the intermediate position 326 to enlarge the opening
301 between the rollers 304 beyond the initially set minimum size.
This enlargement of the opening 301 between the rollers 304 may be
useful in situations where a certain enlarged portion (e.g., a
kink, or a splice between cables) of filamentary material that
exceeds the initial set minimum size of the opening 301 is directed
into the opening 301. In such a situation, the enlarged portion of
the filamentary material, as it passes the rollers 304, will urge
the lower portions 324b of the arms 324 radially outward to spread
the rollers slightly further apart to permit the enlarged portion
to pass, thereby avoiding crushing the enlarged portion and
possibly damaging the filamentary material, or causing the filament
to break.
[0037] The lower portions 324b may be biased by biasing members
(e.g., springs) 328 that extend between the lower portions 324b of
arms 324 and the housing 302. Each arm 324 may have a retainer 324e
(FIG. 11) for retaining an end of a biasing member 328 in
engagement with the arm 324. The biasing members 328 are configured
to urge the lower portions 324b of the arms 324 radially inwardly
toward axis H-H so that, in the example given above, if the rollers
304 temporarily spread apart to permit an enlarged portion to pass,
the biasing members 328 will restore the arms 324 back towards
their initial set position corresponding to the set minimum opening
size of opening 301. Thus, the biasing members 328 permit some
amount of temporary self-adjustment of the rollers 304 even after
an initial minimum opening 301 size is set.
[0038] The apparatus 300 is adjustable and can be set by a user for
filamentary material of different thicknesses (i.e., diameter). To
set the apparatus 300 for a specific thickness of filamentary
material, if the rollers 304 are not already widely spread, a user
can thread (rotate) the ring 320 fully or substantially into collar
302a (e.g., clockwise) in order to spread rollers 304 substantially
apart to set the opening 301 to a large or even maximum size. A
user can then feed a filament (e.g., wire) through the bore 305 of
the ring 320, through the opening 303, and through the opening 301.
Then, a user can thread (rotate) the ring 320 out of collar 302a
(e.g., counterclockwise) to permit the lower portions 324b of the
arms 324 to rotate toward axis H-H due to the force on the arms 324
from springs 328. This will move the rollers 304 toward the central
axis H-H and into contact with the filamentary material, lightly
squeezing the material. Then, the user can thread (rotate) the ring
320 into the collar 302a (e.g., clockwise) again until the opening
301 is large enough for the filamentary material to contact only
one or the other of the rollers 304, but does not contact both
rollers 304.
[0039] There have been described and illustrated herein several
embodiments of an adjustable guide for filamentary material. While
particular embodiments have been described, it is not intended that
the invention be limited thereto, as it is intended that the
invention be as broad in scope as the art will allow and that the
specification be read likewise. Thus, while particular arrangements
for connecting various elements have been disclosed, it will be
appreciated that other suitable arrangements can be used as well.
It will therefore be appreciated by those skilled in the art that
yet other modifications could be made to the provided invention
without deviating from its spirit and scope as claimed.
