BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a yarn winding device for winding yarn around a
winding bobbin.
2. Description of the Related Art
[0002] As a yarn winding device that winds yarn around the winding bobbin while traversing,
there is conventionally known a yarn winding device that changes a traverse speed
of a traverse guide for a smaller diameter region and for a larger diameter region
when producing a conical package (e.g., Japanese Unexamined Patent Publication No.
10-109823). In the conical package, the traverse speed is set to high speed in the smaller
diameter region and the traverse speed is set to low speed in the larger diameter
region to improve a package shape and an unwinding property.
[0003] A value of a ratio of the traverse speed of the traverse guide within the smaller
diameter region with respect to the traverse speed of the traverse guide within the
larger diameter region of the conical package is referred to as a lead ratio. For
example, if the ratio of the traverse speed of the traverse guide within the smaller
diameter region and the traverse speed of the traverse guide within the larger diameter
region is 1.3 : 1.0, the lead ratio is expressed as 1.3. The lead ratio may also be
expressed as a value of a ratio of traverse time of the traverse guide within the
larger diameter region with respect to traverse time of the traverse guide within
the smaller diameter region.
[0004] The traverse guide of the yarn winding device is driven by a traverse driving device
such as a servo motor. The traverse driving device is required to be reversely operated
to reverse the traverse guide at an end of the package. For example, when the lead
ratio is set to 1.3, the traverse driving device is controlled so that the ratio of
the traverse speed of the smaller diameter region to the traverse speed of the larger
diameter region becomes 1.3 : 1.0
[0005] However, when the lead ratio is greater than 1.0, the traverse speed of the smaller
diameter region is increased compared to the case when the lead ratio is 1.0, and
thus acceleration in reversing the traverse guide increases. As a result, a current
supplied to the traverse driving device increases and a maximum current exceeding
a rating may flow. A heat generation amount of the traverse driving device thus may
increase or a limit torque may be easily achieved compared to a case when the lead
ratio is 1.0 even under the same winding condition, thus leading to downgrade in specifications
of the yarn winding device.
BRIEF SUMMARY OF THE INVENTION
[0007] It is an object of the present invention to provide an improved yarn winding device
overcoming the above mentioned problems.
[0008] This object is achieved by a yarn winding device of claims 1, 3 and 4.
[0009] In accordance with embodiments, the present invention provides a yarn winding device
for driving a traverse guide at an appropriate speed profile when setting a lead ratio
and producing a conical package. In accordance with further embodiments, the present
invention provides a yarn winding device for suppressing a peak of a current value
supplied to the traverse driving device and suppressing a heat generation amount of
the traverse driving device by appropriately adjusting the speed profile in a smaller
diameter region of the package when a lead ratio greater than 1.0 is set. In accordance
with yet further embodiments, the present invention provides a yarn winding device
for suppressing a saddle bag of the package by a quick turn of the traverse guide
by appropriately adjusting the speed profile in a larger diameter region of the package
when a lead ratio greater than 1.0 is set.
[0010] According to a first aspect, a yarn winding device that produces a conical package
includes a traverse guide, a traverse driving section, a lead ratio setting section,
and a speed profile adjusting section. The traverse guide is adapted to traverse yarn
to be wound into the package. The traverse driving section is adapted to reciprocate
the traverse guide with respect to a direction of a winding width of the package.
The lead ratio setting section is adapted to set a lead ratio as a set lead ratio,
the lead ratio being a value of a ratio of traverse time of the traverse guide within
a larger diameter region with respect to traverse time of the traverse guide within
a smaller diameter region of the package, or a value of a ratio of traverse speed
of the traverse guide within the smaller diameter region with respect to traverse
speed of the traverse guide within the larger diameter region of the package. The
speed profile adjusting section is adapted to adjust a speed profile of the traverse
guide in at least one of the larger diameter region and the smaller diameter region
of the package according to the set lead ratio set by the lead ratio setting section.
[0011] The speed profile of the traverse driving section thus can be freely adjusted according
to the lead ratio. As a result, the traverse guide can be driven at an appropriate
speed profile when setting the lead ratio and producing the conical package.
[0012] A second aspect is the yarn winding device according to the first aspect, wherein
the speed profile adjusting section adjusts the speed profile of the traverse guide
for both the larger diameter region and the smaller diameter region of the package.
The traverse guide thus can be driven at an appropriate speed profile in both the
larger diameter region and the smaller diameter region when setting the lead ratio
and producing the conical package.
[0013] A third aspect is the yarn winding device according to the first or second aspect,
wherein when the set lead ratio set by the lead ratio setting section is greater than
1.0, the speed profile adjusting section adjusts the speed profile for the smaller
diameter region corresponding to the set lead ratio to a first smaller diameter region
speed profile. Assume that a second smaller diameter region speed profile is the speed
profile for the smaller diameter region corresponding to a reference lead ratio in
which the lead ratio is 1.0. In this case, the speed profile adjusting section adjusts
the speed profile such that acceleration of the traverse guide in the first smaller
diameter region speed profile is at most acceleration of the traverse guide in the
second smaller diameter region speed profile. Therefore, even when the lead ratio
greater than 1.0 is set, the peak of the current value of the traverse driving section
can be suppressed in the smaller diameter region of the package, and the increase
in the heat generation amount of the traverse driving section can be suppressed. As
a result, since the traverse driving section can be operated at high speed in the
smaller diameter region of the package, lowering of productivity of the yarn winding
device can be suppressed.
[0014] A fourth aspect is the yarn winding device according to any of the first and second
aspects, wherein when the set lead ratio set by the lead ratio setting section is
greater than 1.0, the speed profile adjusting section adjusts the speed profile for
the smaller diameter region corresponding to the set lead ratio to a first smaller
diameter region speed profile. Assume that a second smaller diameter region speed
profile is the speed profile for the smaller diameter region corresponding to a reference
lead ratio in which the lead ratio is 1.0. Assume that a third smaller diameter region
speed profile is the speed profile for the smaller diameter region in case the lead
ratio is equal to the set lead ratio and acceleration time of the traverse guide is
equal to acceleration time of the traverse guide in the second smaller diameter region
speed profile. In this case, the speed profile adjusting section adjusts the speed
profile such that acceleration of the traverse guide in the first smaller diameter
region speed profile is smaller than acceleration of the traverse guide in the third
smaller diameter region speed profile. Therefore, even when the lead ratio greater
than 1.0 is set, the peak of the current value of the traverse driving section in
the smaller diameter region of the package can be suppressed, and the increase in
the heat generation amount of the traverse driving section can be suppressed. As a
result, the traverse driving section can be operated at high speed in the smaller
diameter region of the package, and the lowering in productivity of the yarn winding
device can be suppressed.
[0015] A fifth aspect is the yarn winding device according to any of the first and second
aspects, wherein when the set lead ratio set by the lead ratio setting section is
greater than 1.0, the speed profile adjusting section adjusts the speed profile for
the larger diameter region corresponding to the set lead ratio to a first larger diameter
region speed profile. Assume that a second larger diameter region speed profile is
the speed profile of the larger diameter region corresponding to a reference lead
ratio in which the lead ratio is 1.0. In this case, the speed profile adjusting section
adjusts the speed profile such that acceleration of the traverse guide in the first
larger diameter region speed profile is equal to or greater than acceleration of the
traverse guide in the second larger diameter region speed profile. Therefore, if the
lead ratio greater than 1.0 is set, the acceleration of the traverse guide in the
larger diameter region of the package can be increased and the traverse guide can
make a quick turn. As a result, the saddle bag in the larger diameter region of the
package can be suppressed, and the conical package excelling in unwinding property
can be produced.
[0016] A sixth aspect is the yarn winding device according to any of the first and second
aspects, wherein when the set lead ratio set by the lead ratio setting section is
greater than 1.0, the speed profile adjusting section adjusts the speed profile for
the larger diameter region corresponding to the set lead ratio to a first larger diameter
region speed profile. Assume that a second larger diameter region speed profile is
the speed profile for the larger diameter region corresponding to a reference lead
ratio in which the lead ratio is 1.0. Assume that a third larger diameter region speed
profile is the speed profile for the larger diameter region in case the lead ratio
is equal to the set lead ratio and acceleration time of the traverse guide is equal
to acceleration time of the traverse guide in the second larger diameter region speed
profile. In this case, the speed profile adjusting section adjusts the speed profile
such that acceleration of the traverse guide in the first larger diameter region speed
profile is greater than acceleration of the traverse guide in the third larger diameter
region speed profile. Therefore, even when the lead ratio greater than 1.0 is set,
the acceleration of the traverse guide in the larger diameter region of the package
can be increased and the traverse guide can make a quick turn. As a result, the saddle
bag in the larger diameter region of the package can be suppressed, and the conical
package excelling in unwinding property can be produced.
[0017] A seventh aspect is the yarn winding device according to the third aspect, wherein
an acceleration time of the traverse guide for the first smaller diameter region speed
profile is equal to or greater than an acceleration time of the traverse guide for
the second smaller diameter region speed profile. Thus, when the lead ratio greater
than 1.0 is set, the traverse guide makes a turn in the smaller diameter region of
the package by taking time. Therefore, the peak of the current value of the traverse
driving section can be suppressed and the increase in the heat generation amount of
the traverse driving section can be suppressed. As a result, the traverse driving
section can be operated at high speed in the smaller diameter region of the package,
and the productivity of the yarn winding device can be improved.
[0018] An eighth aspect is the yarn winding device according to the fourth aspect, wherein
an acceleration time of the traverse guide for the first smaller diameter region speed
profile is greater than an acceleration time of the traverse guide for the third smaller
diameter region speed profile. Thus, when the lead ratio greater than 1.0 is set,
the traverse guide makes a turn in the smaller diameter region of the package by taking
time. Therefore, the peak of the current value of the traverse driving section can
be suppressed and the increase in the heat generation amount of the traverse driving
section can be suppressed. As a result, the traverse driving section can be operated
at high speed in the smaller diameter region of the package, and the lowering in productivity
of the yarn winding device can be suppressed.
[0019] A ninth aspect is the yarn winding device according to the fifth aspect, wherein
acceleration time of the traverse guide for the first larger diameter region speed
profile is at most acceleration time of the traverse guide for the second larger diameter
region speed profile. Therefore, even when the lead ratio greater than 1.0 is set,
the acceleration of the traverse guide in the larger diameter region of the package
can be increased and the traverse guide can make a quick turn. As a result, the saddle
bag in the larger diameter region of the package can be suppressed, and the conical
package excelling in unwinding property can be produced.
[0020] A tenth aspect is the yarn winding device according to the sixth aspect, wherein
the acceleration time of the traverse guide for the first larger diameter region speed
profile is set shorter than the acceleration time of the traverse guide for the third
larger diameter region speed profile. Therefore, even when the lead ratio greater
than 1.0 is set, the acceleration of the traverse guide in the larger diameter region
of the package can be increased and the traverse guide can make a quick turn. As a
result, the saddle bag in the larger diameter region of the package can be suppressed,
and the conical package excelling in unwinding property can be produced.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0022] Embodiments of the present invention will now be described with reference to the
drawings.
[0023] A yarn winding device 11 according to a first embodiment of the present invention
will be described with reference to FIGS. 1 to 3C.
[0024] As illustrated in FIG. 1, the yarn winding device 11 of the present embodiment is
a yarn winding device that forms a yarn layer by winding yarn Y of a yarn feeding
bobbin 51 around a winding tube 52 while traversing the yarn Y with a traverse device
12 to produce a conical package 53. Although one yarn winding device 11 is illustrated
in FIG. 1, a plurality of yarn winding devices 11 may be arranged in line to configure
an automatic winder.
[0025] In this specification, the winding tube 52 and the package 53 are collectively referred
to as a winding bobbin B. In other words, the winding bobbin B in which the yarn layer
is not formed is the winding tube 52, and the winding bobbin B in which the yarn layer
is formed is the package 53. A smaller diameter region and a larger diameter region
of the package 53 respectively indicate regions of a smaller diameter half and a larger
diameter half with a central part in a width direction of the package 53 as a boundary.
[0026] An overview of the yarn winding device 11 will be described first. As illustrated
in FIG. 1, the yarn winding device 11 includes a cradle 13 for supporting the winding
bobbin B in an attachable/detachable manner, and a contact roller 14 driven and rotated
while making contact with a peripheral surface of the winding bobbin B. The cradle
13 is configured to freely swing with swing shaft 15 as a center, and supports both
ends of the winding bobbin B in a freely rotating manner. When the yarn Y is wound
around the winding bobbin B and a diameter of the winding bobbin B is increased, the
cradle 13 swings so that an appropriate contact between the peripheral surface of
the winding bobbin B and the contact roller 14 is maintained.
[0027] The cradle 13 includes a winding bobbin drive motor 18 serving as a winding bobbin
driving section. When the winding bobbin B is set to the cradle 13, a drive shaft
of the winding bobbin drive motor 18 is coupled to the winding bobbin B in a relatively
non-rotatable manner (so-called direct drive method). The yarn winding device 11 winds
the yarn Y into the package 53 by actively rotation driving the winding bobbin B with
the winding bobbin drive motor 18.
[0028] The cradle 13 is provided with a winding bobbin rotation speed sensor 32 and a winding
bobbin diameter sensor 33. The winding bobbin rotation speed sensor 32 detects a rotation
speed of the winding bobbin B. The winding bobbin diameter sensor 33 detects a diameter
of the winding bobbin B. The winding bobbin diameter sensor 33 is a rotary encoder
or the like, and detects the diameter of the winding bobbin B by detecting a swing
angle of the cradle 13.
[0029] The traverse device 12 is arranged in proximity to the contact roller 14. The yarn
Y is wound around the winding bobbin B while being traversed by the traverse device
12. The traverse device 12 includes a traverse guide 17 and a traverse guide drive
motor 19 serving as a traverse driving section. The traverse guide 17 engages with
the yarn Y to traverse the yarn Y. The traverse guide drive motor 19 reciprocates
the traverse guide 17 with respect to a direction of the winding width of the winding
bobbin B. The traverse guide 17 is arranged at a tip of an arm member 16 configured
to freely oscillate. The traverse guide 17 is reciprocated by reciprocating the arm
member 16 with the traverse guide drive motor 19 as illustrated with an arrow in FIG.
1. In the present embodiment, a servo motor is used for the traverse guide drive motor
19, but a step motor or the like may also be used.
[0030] A tension applying device 20, a yarn splicing device 21, and a yarn clearer 22 are
arranged in order from the yarn feeding bobbin 51 side on a yarn travelling path between
the yarn feeding bobbin 51 and the contact roller 14. The tension applying device
20 applies an appropriate tension to the yarn Y. The yarn clearer 22 detects a thickness
of the yarn Y passing through a detecting section by a sensor, and analyzes a signal
from the sensor by an analyzer 23 to detect a yarn defect such as slub. The yarn clearer
22 is provided with a cutter for immediately cutting the yarn Y when the yarn defect
is detected. The yarn splicing device 21 splices a lower yarn from the yarn feeding
bobbin 51 and an upper yarn from the winding bobbin B after the yarn clearer 22 detects
the yarn defect and cuts the yarn, or after yarn breakage of the yarn Y from the yarn
feeding bobbin 51.
[0031] A lower yarn catching and guiding section 24 for sucking and catching the lower yarn
from the yarn feeding bobbin 51 and guiding the same to the yarn splicing device 21
is arranged upstream of the yarn splicing device 21. An upper yarn catching and guiding
section 27 for sucking and catching the upper yarn from the winding bobbin B and guiding
the same to the yarn splicing device 21 is arranged downstream of the yarn splicing
device 21. The lower yarn catching and guiding section 24 is formed in a pipe shape,
and is arranged capable of swinging in a vertical direction with a shaft 25 as the
center. A suction hole 26 is formed at a distal end side of the lower yarn catching
and guiding section 24. The upper yarn catching and guiding section 27 is also formed
in a pipe shape, and is arranged capable of swinging in the vertical direction with
a shaft 28 as the center. A mouth 29 is arranged at the distal end side of the upper
yarn catching and guiding section 27. The lower yarn catching and guiding section
26 and the upper yarn catching and guiding section 27 are respectively connected to
a negative pressure source to cause the suction hole 26 and the mouth 29 at the distal
ends to generate a sucking force.
[0032] A configuration for controlling an operation of the yarn winding device 11 will now
be described. In the present embodiment, as illustrated in FIG. 1, the winding bobbin
drive motor 18 for driving the winding bobbin B and the traverse guide drive motor
19 for driving the traverse guide 17 are separately and independently arranged, so
that the drive of the winding bobbin B and the traverse guide 17 is separately and
independently controlled. The drive of the traverse guide 17 by the traverse guide
drive motor 19 is controlled based on a speed profile.
[0033] The speed profile is information on the drive of the traverse guide 17, and includes
the setting of a traverse time of the traverse guide 17, a traverse speed, an acceleration
time of the traverse guide 17, acceleration of the traverse guide 17, and the like.
The speed profile is adjusted separately for the smaller diameter region and the larger
diameter region of the package 53. Herein, "adjusted separately" also means adjusting
individually or independently for the smaller diameter region and the larger diameter
region. In the smaller diameter region of the package 53, the drive of the traverse
guide 17 is controlled based on a first smaller diameter region speed profile. In
the larger diameter region of the package 53, the drive of the traverse guide 17 is
controlled based on a first larger diameter region speed profile.
[0034] A lead ratio is a value of the ratio of the traverse speed of the traverse guide
17 within the smaller diameter region with respect to the traverse speed of the traverse
guide 17 within the larger diameter region in the conical package 53 described above.
For example, if the ratio of the traverse speed of the traverse guide 17 within the
smaller diameter region and the traverse speed of the traverse guide 17 within the
larger diameter region is set to 1.3 : 1.0, the lead ratio is expressed as 1.3. The
lead ratio may also be expressed in percentages such as 130 percent : 100 percent.
The lead ratio may not be expressed with the value of the ratio of the traverse speeds,
but may be expressed with the value of the ratio of the traverse time, that is, the
value of the ratio of the traverse time of the traverse guide 17 within the larger
diameter region with respect to the traverse time of the traverse guide 17 within
the smaller diameter region. In the present embodiment, the lead ratio will be described
as the value of the ratio of the traverse time.
[0035] As illustrated in FIG. 1, the yarn winding device 11 includes a unit control section
41 for individually controlling the yarn winding device 11. The unit control section
41 is connected with a winding bobbin drive control section 31 and a traverse control
section 34. The winding bobbin drive control section 31 controls drive and stop of
the winding bobbin drive motor 18 based on a control signal from the unit control
section 41. The traverse control section 34 controls drive and stop of the traverse
guide drive motor 19 based on a control signal from the unit control section 41. The
unit control section 41 is connected to a machine control section 42. The machine
control section 42 collectively controls a plurality of yarn winding devices 11 that
configure the automatic winder.
[0036] The unit control section 41, the machine control section 42, the winding bobbin drive
control section 31, and the traverse control section 34 include a Central Processing
Unit (CPU) serving as an operating section, a Read Only Memory (ROM), a Random Access
Memory (RAM) or the like serving as a storage device, and the like. The ROM of the
traverse control section 34 stores control software for causing hardware such as the
CPU arranged in the traverse control section 34 to operate as a control section based
on the speed profile.
[0037] A rotation speed signal of the winding bobbin B detected by the winding bobbin rotation
speed sensor 32 is transmitted to the unit control section 41, the winding bobbin
drive control section 31, and the traverse control section 34. A diameter signal of
the winding bobbin B detected by the winding bobbin diameter sensor 33 is transmitted
to the unit control section 41, and is transferred from the unit control section 41
to the winding bobbin drive control section 31 and the traverse control section 34.
[0038] The machine control section 42 includes a lead ratio setting section 43. The traverse
control section 34 includes a speed profile adjusting section 44. The lead ratio setting
section 43 sets the value of the ratio of the traverse time of the traverse guide
17 within the larger diameter region with respect to the traverse time of the traverse
guide 17 within the smaller diameter region of the package 53 as the lead ratio (e.g.,
1.3). The lead ratio that is set is a set lead ratio. The speed profile adjusting
section 44 adjusts the first smaller diameter region speed profile and the first larger
diameter region speed profile according to the set lead ratio (see FIGS. 2C and 3C).
The first smaller diameter region speed profile and the first larger diameter region
speed profile will be described in detail later.
[0039] The machine control section 42 transmits the set lead ratio set by the lead ratio
setting section 43 to the unit control section 41 of the yarn winding device 11. The
unit control section 41 transmits the received set lead ratio to the traverse control
section 34. When receiving the set lead ratio, the traverse control section 34 controls
the drive and stop of the traverse guide drive motor 19 so as to drive the traverse
guide 17 according to the first smaller diameter region speed profile and the first
larger diameter region speed profile determined based on the set lead ratio.
[0040] Next, the first smaller diameter region speed profile and the first larger diameter
region speed profile adjusted by the speed profile adjusting section 44 in the yarn
winding device 11 of the present embodiment will be described.
[0041] FIGS. 2A to 2C illustrate the speed profiles of the smaller diameter region of the
package 53. FIGS. 3A to 3C illustrate the speed profiles of the larger diameter region
of the package 53. A horizontal axis indicates the traverse time, and a vertical axis
indicates the traverse speed. FIG. 2C illustrates the first smaller diameter region
speed profile adjusted by the speed profile adjusting section 44 in the present embodiment.
FIG. 3C illustrates the first larger diameter region speed profile. A second smaller
diameter region speed profile illustrated in FIG. 2A and a third smaller diameter
region speed profile illustrated in FIG. 2B are illustrated in contrast to the first
smaller diameter region speed profile. A second larger diameter region speed profile
illustrated in FIG. 3A and a third larger diameter region speed profile illustrated
in FIG. 3B are illustrated in contrast to the first larger diameter region speed profile.
[0042] FIGS. 2A to 2C illustrate only a case in which the speed of the traverse guide 17
is increased from the end in the smaller diameter region of the package 53 towards
the central part in the width direction of the package 53 (a case in which the acceleration
is positive), but a similar speed profile applies to a case in which the speed of
the traverse guide 17 is reduced (a case in which the acceleration is negative). FIGS.
3A to 3C illustrate only a case in which the speed of the traverse guide 17 is increased
from the end in the larger diameter region of the package 53 towards the central part
in the width direction of the package 53 (a case in which the acceleration is positive),
but similar speed profile applies to a case in which the speed of the traverse guide
17 is reduced (a case in which the acceleration is negative).
[0043] The second smaller diameter region speed profile illustrated in FIG. 2A is the speed
profile for the smaller diameter region when the lead ratio is 1.0. The second larger
diameter region speed profile illustrated in FIG. 3A is the speed profile for the
larger diameter region when the lead ratio is 1.0. The case in which the lead ratio
is 1.0 is the case in which the set lead ratio becomes 1.0 by operating the lead ratio
setting section 43 and inputting 1.0 for the lead ratio. The lead ratio of 1.0, will
be referred to as a "reference lead ratio". Since the lead ratio is not set if a function
of the lead ratio setting section 43 is turned OFF, the lead ratio may not be provided,
that is, the set lead ratio may be 1.0.
[0044] A determining condition of the second smaller diameter region speed profile and the
second larger diameter region speed profile is determined by a winding condition of
the conical package 53. The determining condition of the second smaller diameter region
speed profile includes a traverse time t1, a traverse speed v1, an acceleration time
t11 of the traverse guide 17, acceleration v1/t11 of the traverse guide 17, and the
like. The determining condition of the second larger diameter region speed profile
includes a traverse time T1, a traverse speed V1, an acceleration time T11 of the
traverse guide 17, acceleration V1/T11 of the traverse guide 17, and the like. The
winding condition includes a winding width, the number of winds, and a manner of winding
(precision winding, random winding, etc.). The second smaller diameter region speed
profile and the second larger diameter region speed profile of the present embodiment
have the traverse time t1 of the smaller diameter region and the traverse time T1
of the larger diameter region set equal, the traverse speed v1 of the smaller diameter
region and the traverse speed V1 of the larger diameter region set equal, the acceleration
time t11 of the smaller diameter region and the acceleration time T11 of the larger
diameter region set equal, and the acceleration (v1/t11) of the smaller diameter region
and the acceleration (V11/T11) of the larger diameter region set equal.
[0045] The third smaller diameter region speed profile illustrated in FIG. 2B, is a speed
profile for the smaller diameter region when the lead ratio same as the set lead ratio
(e.g., 1.3) is set. The third larger diameter region speed profile illustrated in
FIG. 3B is a speed profile for the larger diameter region when the lead ratio same
as the set lead ratio (e.g., 1.3) is set.
[0046] Comparing the second smaller diameter region speed profile and the third smaller
diameter region speed profile based on FIGS. 2A and 2B, since the lead ratios are
different, i.e., 1.0 and 1.3, the traverse time t2 in the third smaller diameter region
speed profile is reduced than the traverse time t1 in the second smaller diameter
region speed profile. The traverse guide 17 is required to be moved to the central
part in the width direction of the package 53 by the traverse time t2 that is shorter
than the traverse time t1, and thus the traverse speed v2 in the third smaller diameter
region speed profile is increased than the traverse speed v1 in the second smaller
diameter region speed profile by the reduction of the traverse time t2. The acceleration
time t11 in the third smaller diameter region speed profile is the same as the acceleration
time t11 in the second smaller diameter region speed profile. Therefore, the acceleration
(v2/t11) in the third smaller diameter region speed profile is increased than the
acceleration (v1/t11) in the second smaller diameter region speed profile.
[0047] Therefore, if the speed profile in which the acceleration of the traverse guide 17
is increased is set for the smaller diameter region of the package 53, the current
to be supplied to the traverse guide drive motor 19 increases and a maximum current
exceeding the rating may flow. Accordingly, even under the same winding condition,
the heat generation amount of the traverse guide drive motor 19 thus may be increased
or the limit torque may be easily reached compared to the case when the lead ratio
is 1.0, thus leading to downgrade in specifications of the yarn winding device 11.
[0048] In order to resolve such problems, as illustrated in FIG. 2C, in the first smaller
diameter region speed profile of the present embodiment, the acceleration is at most
the acceleration (v1/t11) in the second smaller diameter region speed profile in which
the lead ratio is 1.0. Specifically, the acceleration in the first smaller diameter
region speed profile is made equal to the acceleration (v1/t11) in the second smaller
diameter region speed profile. In the first smaller diameter region speed profile,
the acceleration is reduced, but the traverse time t2 is made the same as the third
smaller diameter region speed profile, and the traverse speed v3, the acceleration
time t31, and the time t32 of traversing at the traverse speed v3 are differed from
the third smaller diameter region speed profile so that the traverse distance and
the average traverse speed become equal irrespective of the adjustment of the speed
profile.
[0049] Next, the second larger diameter region speed profile and the third larger diameter
region speed profile are compared with reference to FIGS. 3A and 3B. Since the lead
ratios are different, i.e., 1.0 and 1.3, the traverse time T2 in the third larger
diameter region speed profile is increased than the traverse time T1 in the second
larger diameter region speed profile. The traverse guide 17 is required to be moved
to the central part in the width direction of the package 53 by the traverse time
T2 that is longer than the traverse time T1. Thus, the traverse speed V2 in the third
larger diameter region speed profile is reduced than the traverse speed V1 in the
second larger diameter region speed profile by the increase of the traverse time T2.
The acceleration time T11 in the third larger diameter region speed profile is the
same as the acceleration time T11 in the second larger diameter region speed profile.
Therefore, the acceleration (V2/T11) in the third larger diameter region speed profile
is reduced than the acceleration (V1/T11) in the second larger diameter region speed
profile.
[0050] In the first larger diameter region speed profile of the present embodiment, in order
to solve the problem of the saddle bag, as illustrated in FIG. 3C, the acceleration
is equal to or greater than the acceleration (V1/T11) in the second larger diameter
region speed profile in which the lead ratio is 1.0. Specifically, the acceleration
in the first larger diameter region speed profile is made equal to the acceleration
(V1/T11) in the second larger diameter region speed profile. The acceleration is set
large in the first larger diameter region speed profile. However, the traverse time
T2 is made the same as the third larger diameter region speed profile, and the traverse
speed V3, the acceleration time T31, and the time T32 of traversing at the traverse
speed V3 are differed from the third larger diameter region speed profile so that
the traverse distance and the average traverse speed become equal irrespective of
the adjustment of the speed profile.
[0051] The yarn winding device 11 according to the first embodiment described above has
the following effects.
[0052] The speed profile adjusting section 44 adjusts the speed profile of the traverse
guide 17 in both the larger diameter region and the smaller diameter region of the
package 53. Thus, when setting the lead ratio and producing the conical package 53,
the traverse guide 17 can be driven at the appropriate speed profile in both the larger
diameter region and the smaller diameter region.
[0053] When the set lead ratio set by the lead ratio setting section 43 is greater than
1.0, the speed profile adjusting section 44 adjusts the acceleration of the traverse
guide 17 in the first smaller diameter region speed profile to at most the acceleration
of the traverse guide 17 in the second smaller diameter region speed profile. Thus,
when the lead ratio greater than 1.0 is set, the peak of the current value of the
traverse guide drive motor 19 in the smaller diameter region of the package 53 can
be suppressed, and the increase in the heat generation amount of the traverse guide
drive motor 19 can be suppressed. As a result, the traverse guide drive motor 19 can
be operated at high speed in the smaller diameter region of the package 53, and the
lowering in productivity of the yarn winding device 11 can be suppressed.
[0054] When the set lead ratio set by the lead ratio setting section 43 is greater than
1.0, the speed profile adjusting section 44 adjusts the acceleration of the traverse
guide 17 in the first larger diameter region speed profile to be equal to or greater
than the acceleration of the traverse guide 17 in the second larger diameter region
speed profile in which the lead ratio is 1.0. Thus, when the lead ratio greater than
1.0 is set, the acceleration of the traverse guide 17 in the larger diameter region
of the package 53 can be made large, and the traverse guide 17 can make a quick turn.
As a result, the saddle bag in the larger diameter region of the package 53 can be
suppressed, and the conical package 53 excelling in unwinding property can be produced.
[0055] The acceleration time of the traverse guide 17 for the first smaller diameter region
speed profile is equal to or greater than the acceleration time of the traverse guide
17 for the second smaller diameter region speed profile. Thus, when the lead ratio
greater than 1.0 is set, the traverse guide 17 makes a turn in the smaller diameter
region of the package 53 by taking time. Therefore, the peak of the current value
of the traverse guide drive motor 19 can be suppressed, and the increase in the heat
generation amount of the traverse guide drive motor 19 can be suppressed. As a result,
the traverse guide drive motor 19 can be operated at high speed in the smaller diameter
region of the package 53, and the lowering in productivity of the yarn winding device
11 can be suppressed.
[0056] The acceleration time of the traverse guide 17 for the first larger diameter region
speed profile is at most the acceleration time of the traverse guide 17 for the second
larger diameter region speed profile. Thus, when the lead ratio greater than 1.0 is
set, the acceleration of the traverse guide 17 in the larger diameter region of the
package 53 can be made large, and the traverse guide 17 can make a quick turn. As
a result, the saddle bag in the larger diameter region of the package 53 can be suppressed,
and the conical package 53 excelling in unwinding property can be produced.
[0057] The yarn winding device 11 according to a second embodiment of the present invention
will be described with reference to FIGS. 4A to 4C and FIGS. 5A to 5C. The yarn winding
device 11 according to the present embodiment greatly differs from the first embodiment
in the following two points. A first difference lies in that the acceleration of the
traverse guide 17 in the first smaller diameter region speed profile is smaller than
the acceleration of the traverse guide 17 in the third smaller diameter region speed
profile, and greater than the acceleration of the traverse guide 17 in the second
smaller diameter region speed profile. A second difference lies in that the acceleration
of the traverse guide 17 in the first larger diameter region speed profile is greater
than the acceleration of the traverse guide 17 in the third larger diameter region
speed profile, and smaller than the acceleration of the traverse guide 17 in the second
larger diameter region speed profile. Other configurations and controls are similar
to the first embodiment, and hence the detailed description thereof will be omitted.
[0058] FIGS. 4A to 4C illustrate the speed profiles for the smaller diameter region of the
package 53. FIGS. 5A to 5C illustrate the speed profiles for the larger diameter region
of the package 53. The horizontal axis indicates the traverse time, and the vertical
axis indicates the traverse speed. FIG. 4C illustrates the first smaller diameter
region speed profile adjusted by the speed profile adjusting section 44 in the present
embodiment. FIG. 5C illustrates the first larger diameter region speed profile adjusted
by the speed profile adjusting section 44 in the present embodiment. A second smaller
diameter region speed profile illustrated in FIG. 4A and a third smaller diameter
region speed profile illustrated in FIG. 4B are illustrated in contrast to the first
smaller diameter region speed profile. A second larger diameter region speed profile
illustrated in FIG. 5A and a third larger diameter region speed profile illustrated
in FIG. 5B are illustrated in contrast to the first larger diameter region speed profile.
The second smaller diameter region speed profile, the third smaller diameter region
speed profile, the second larger diameter region speed profile, and the third larger
diameter region speed profile are set similar to the first embodiment, and hence the
detailed description thereof will be omitted.
[0059] FIGS. 4A to 4C illustrate only a case in which the speed of the traverse guide 17
is increased from the end in the smaller diameter region of the package 53 towards
the central part in the width direction of the package 53 (a case in which the acceleration
is positive), but a similar speed profile applies to a case in which the speed of
the traverse guide 17 is reduced (a case in which the acceleration is negative) .
FIGS. 5A to 5C illustrate only a case in which the speed of the traverse guide 17
is increased from the end in the larger diameter region of the package 53 towards
the central part in the width direction of the package 53 (a case in which the acceleration
is positive), but a similar speed profile applies to a case in which the speed of
the traverse guide 17 is reduced (a case in which the acceleration is negative).
[0060] As illustrated in FIG. 4C, in the first smaller diameter region speed profile of
the present embodiment, the acceleration is set to be smaller than the acceleration
(v2/t11) in the third smaller diameter region speed profile and greater than the acceleration
(V1/t11) in the second smaller diameter region speed profile. In the first smaller
diameter region speed profile, the traverse time t2 is made the same as the third
smaller diameter region speed profile, and the traverse speed v4, the acceleration
time t41, and the time t42 of traversing at the traverse speed v4 are differed from
the third smaller diameter region speed profile so that the traverse distance and
the average traverse speed become equal irrespective of the adjustment of the speed
profile.
[0061] As illustrated in FIG. 5C, in the first larger diameter region speed profile of the
present embodiment, the acceleration is set to be greater than the acceleration (V2/T11)
in the third larger diameter region speed profile and smaller than the acceleration
(V1/T11) in the second larger diameter region speed profile. In the first larger diameter
region speed profile, the traverse time T2 is made the same as the third larger diameter
region speed profile, and the traverse speed V4, the acceleration time T41, and the
time T42 of traversing at the traverse speed V4 are differed from the third smaller
diameter region speed profile so that the traverse distance and the average traverse
speed become equal irrespective of the adjustment of the speed profile.
[0062] The yarn winding device 11 according to the second embodiment described above has
the following effects.
[0063] The speed profile adjusting section 44 adjusts the acceleration of the traverse guide
17 in the first smaller diameter region speed profile to be smaller than the acceleration
of the traverse guide 17 in the third smaller diameter region speed profile when the
set lead ratio set by the lead ratio setting section 43 is greater than 1.0. Thus,
when the lead ratio greater than 1.0 is set, the peak of the current value of the
traverse guide drive motor 19 in the smaller diameter region of the package 53 can
be suppressed, and the increase in the heat generation amount of the traverse guide
drive motor 19 can be suppressed. As a result, the traverse guide drive motor 19 can
be operated at high speed in the smaller diameter region of the package 53, and the
lowering in productivity of the yarn winding device 11 can be suppressed.
[0064] When the set lead ratio set by the lead ratio setting section 43 is greater than
1.0, the speed profile adjusting section 44 adjusts the acceleration of the traverse
guide 17 in the first larger diameter region speed profile to greater than the acceleration
of the traverse guide 17 in the third larger diameter region speed profile. Thus,
when the lead ratio greater than 1.0 is set, the acceleration of the traverse guide
17 in the larger diameter region of the package 53 can be made large, and the traverse
guide 17 can make a quick turn. As a result, the saddle bag in the larger diameter
region of the package 53 can be suppressed, and the conical package 53 excelling in
unwinding property can be produced.
[0065] The acceleration time of the traverse guide 17 for the first smaller diameter region
speed profile is greater than the acceleration time of the traverse guide 17 for the
third smaller diameter region speed profile. Thus, when the lead ratio greater than
1.0 is set, the traverse guide 17 makes a turn in the smaller diameter region of the
package 53 by taking time. Therefore, the peak of the current value of the traverse
guide drive motor 19 can be suppressed, and the increase in the heat generation amount
of the traverse guide drive motor 19 can be suppressed. As a result, the traverse
guide drive motor 19 can be operated at high speed in the smaller diameter region
of the package 53, and the lowering in productivity of the yarn winding device 11
can be suppressed.
[0066] The acceleration time of the traverse guide 17 for the first larger diameter region
speed profile is smaller than the acceleration time of the traverse guide 17 for the
third larger diameter region speed profile. Thus, when the lead ratio greater than
1.0 is set, the acceleration of the traverse guide 17 in the larger diameter region
of the package 53 can be made large. The traverse guide 17 thus can make a quick turn.
As a result, the saddle bag in the larger diameter region of the package 53 can be
suppressed, and the conical package 53 excelling in unwinding property can be produced.
[0067] The embodiments of the present invention have been described above, but the present
invention is not limited to the above-described embodiments, and various modifications
may be made. For example, the speed linearly accelerates at the time of acceleration
of the traverse guide 17, but the speed may also accelerate in a step-wise manner
or in a curved manner.
[0068] In the first embodiment, the acceleration of the traverse guide 17 in the first smaller
diameter region speed profile is equal to the acceleration (v1/t11) of the traverse
guide 17 in the second smaller diameter region speed profile, but the acceleration
of the traverse guide 17 in the first smaller diameter region speed profile may be
smaller than the acceleration (v1/t11) of the traverse guide 17 in the second smaller
diameter region speed profile. In this case, the acceleration of the traverse guide
17 becomes smaller, but adjustment can be made to increase the acceleration time or
to increase the traverse speed so that the traverse distance and the average traverse
speed become equal irrespective of the adjustment of the speed profile. Similarly,
the acceleration of the traverse guide 17 in the first larger diameter region speed
profile is equal to the acceleration (V1/T11) of the traverse guide 17 in the second
larger diameter region speed profile, but the acceleration of the traverse guide 17
in the first larger diameter region speed profile may be greater than the acceleration
(V1/T11) of the traverse guide 17 in the second larger diameter region speed profile.
In this case, the acceleration of the traverse guide 17 becomes larger, but adjustment
can be made to reduce the acceleration time or to reduce the traverse speed so that
the traverse distance and the average traverse speed become equal irrespective of
the adjustment of the speed profile.
[0069] The first smaller diameter region speed profile and the first larger diameter region
speed profile in the first embodiment and the second embodiment have the speed profile
adjusted with a magnitude relationship of the acceleration of the traverse guide 17
as a reference with respect to the second smaller diameter region speed profile and
the third smaller diameter region speed profile, and the second larger diameter region
speed profile and the third larger diameter region speed profile, which are to be
compared. However, the present invention is not limited thereto, and the speed profile
may be adjusted with a magnitude relationship of the acceleration time of the traverse
guide 17 as a reference.
[0070] The lead ratio in the first embodiment and the second embodiment has been described
as the value of the ratio of the traverse time, but the lead ratio may be set as the
value of the ratio of the traverse speed. It should be noted that if the package 53
is wound by precision winding (method of winding the package 53 while maintaining
the number of winds by the traverse device 12 at a constant value even if the wound
diameter of the package 53 increases, where a traversing angle becomes smaller as
the diameter of the package 53 increases), the package 53 cannot be wound at a predetermined
number of winds unless the lead ratio is set as the value of the ratio of the traverse
time. On the other hand, if the package 53 is wound by random winding (method of winding
the package 53 at a constant winding speed and a constant traverse speed, where the
number of winds changes with change in the diameter of the package 53), the package
53 can be wound even if the lead ratio is set as the value of the ratio of the traverse
time or as the value of the ratio of the traverse speed.
[0071] The configuration for controlling the operation of the yarn winding device 11 is
not limited to the embodiments, and for example, the winding bobbin drive control
section 31 and the traverse control section 34 may be arranged in the unit control
section 41, or the lead ratio setting section 43 arranged in the machine control section
42 may be arranged in the unit control section 41.
[0072] The winding bobbin B is directly driven by the winding bobbin drive motor 18, but
a drive roller may be made in contact with the surface of the winding bobbin B to
drive the winding bobbin B. The shape of the contact roller 14 is a conical shape
in which the diameters of both ends are different, but the shape may also be a cylindrical
shape in which the diameters of both ends are the same.
[0073] The traverse device 12 is configured such that a longitudinal direction of the arm
member 16 is parallel to an installing direction (vertical direction) of the yarn
winding device 11, but the traverse device 12 may be configured such that the longitudinal
direction of the arm member 16 is perpendicular to an installing surface of the yarn
winding device 11. The traverse device 12 is configured such that the arm member 16
reciprocates by the traverse guide drive motor 19, but an endless timing belt may
be arranged in proximity to the contact roller 14, the traverse guide 17 may be attached
to the timing belt and the timing belt may be reciprocated by a pulse motor, or the
like.
