TECHNICAL FIELD
[0001] The present disclosure relates to a yarn information acquiring device, a yarn winding
machine, and a textile machine system.
BACKGROUND
[0002] In a yarn winding machine such as an automatic winder and a spinning machine, when
yarn is wound to form a package, yarn information indicating the state of the yarn
may be acquired at regular time intervals (e.g., for each shift). Patent
US 5,555,712, family member of
JP H07 138822 A, describes such a yarn information acquiring device according to the preamble of
the independent claim 1.
[0003] JP H07 133527 A discloses a process for measuring a yarn length regardless of traveling speed and
time of a yarn. A pattern consisting of a principal wavelength of the yarn is analyzed
and the patterns are counted to determine the length of the yarn based thereon.
SUMMARY
[0004] If some event occurs in a package formed by a yarn winding machine described above
in a subsequent process, it is difficult to identify the cause of occurrence of the
event on the basis of yarn information acquired at regular time intervals.
[0005] In view of this, an object of the present disclosure is to provide a yarn information
acquiring device, a yarn winding machine, and a textile machine system that, if some
event occurs in a package in a subsequent process after a process of forming the package,
enables the cause of occurrence of the event to be easily identified.
[0006] A yarn information acquiring device according to embodiments of the present disclosure
includes a yarn information acquiring section that, when yarn is wound to form a package
in a yarn winding machine, acquires yarn information indicating a state of the yarn.
The yarn information acquiring section manages the yarn information by the package,
and acquires the yarn information for each of divided yarn lengths that are a plurality
of lengths into which a fully wound yarn length in the package fully wound is divided.
[0007] With this yarn information acquiring device, the yarn information is acquired for
each divided yarn length to be managed on a package-by-package basis, and thus if
some event occurs in a package in a subsequent process after the process of forming
the package, the cause of occurrence of the event can be easily identified.
[0008] The yarn information acquiring device according to embodiments of the present disclosure
may further include a yarn information storage section that stores the yarn information
by the package and for each divided yarn length. By this configuration, the cause
of occurrence of an event that occurs in apackage can be identified in the yarn information
acquiring device.
[0009] In the yarn information acquiring device according to embodiments of the present
disclosure, the divided yarn lengths may be lengths into which the fully wound yarn
length is divided by a value within a range equal to or larger than 10 and equal to
or smaller than 1000. By this setting, even with a limited storage capacity (memory),
temporal change of the yarn information can be acquired in an identifiable manner
(in a visualized manner) while the memory is being efficiently used.
[0010] In the yarn information acquiring device according to embodiments of the present
disclosure, the yarn information acquiring section may acquire first yarn information
that is the yarn information for each of first yarn lengths that are the divided yarn
lengths, and acquire second yarn information that is the yarn information for each
of second yarn lengths that are the divided yarn lengths. While the pattern of temporal
change of yarn information to be acquired is being focused on, the number of divisions
is reduced (i.e., the divided yarn length is increased) for yarn information temporal
change of which is small, whereby the amount of yarn information acquired for one
package can be reduced. Thus, even with a limited storage capacity (memory), the number
of types of yarn information to be acquired can be increased. Thus, the divided yarn
length for acquiring yarn information can be set from the viewpoint of temporal changes,
and temporal changes of respective pieces of yarn information of various types can
be acquired in an identifiable manner (each in a visualized manner) while the memory
is being efficiently used.
[0011] In the yarn information acquiring device according to embodiments of the present
disclosure, the second yarn lengths may be longer than the first yarn lengths, the
first yarn information may be information indicating tension generated in the yarn
when the yarn is wound, and the second yarn information may be information indicating
thickness of the yarn. By this setting, change in tension and change in the thickness
of yarn that are pieces of important information for grasping quality of a package
can be acquired such that each change can be identified (each in a visualized manner)
while the memory is being efficiently used.
[0012] In the yarn information acquiring device according to embodiments of the present
disclosure, the yarn information acquiring section may acquire, for each divided yarn
length, environmental information indicating at least one of temperature and humidity
in an area where the yarn winding machine is installed. By this configuration, whether
at least one of the temperature and the humidity is concerned as a cause of occurrence
of an event that occurs in a package can be analyzed.
[0013] In the yarn information acquiring device according to embodiments of the present
disclosure, the yarn information acquiring section may acquire, for each divided yarn
length, operating information indicating at least one of an operating condition and
an operating state of the yarn winding machine . By this configuration, whether at
least one of the operating condition and the operating state is concerned as a cause
of occurrence of an event that occurs in a package can be analyzed.
[0014] In the yarn information acquiring device according to embodiments of the present
disclosure, when each package is formed with a plurality of yarn supplying bobbins,
the yarn information acquiring section may acquire the yarn information by the yarn
supplying bobbin. By this configuration, whether a certain yarn supplying bobbin is
concerned as a cause of occurrence of an event that occurs in a package can be analyzed.
[0015] In the yarn information acquiring device according to embodiments of the present
disclosure, when each package is formed with at least one can, the yarn information
acquiring section may acquire the yarn information by the can. By this configuration,
whether a certain can is concerned as a cause of occurrence of an event that occurs
in a package can be analyzed.
[0016] In the yarn information acquiring device according to embodiments of the present
disclosure, the yarn information acquiring section may acquire event information indicating
an event that occurs in the yarn together with time information when the yarn is wound
to form the package in the yarn winding machine. By this configuration, whether an
event that occurs in yarn when a package is formed is concerned as a cause of occurrence
of an event that occurs in the package can be analyzed.
[0017] In the yarn information acquiring device according to embodiments of the present
disclosure, the event information may be information indicating joining of the yarn.
By this setting, whether joining of yarn is concerned as a cause of occurrence of
an event that occurs in a package can be analyzed.
[0018] A yarn information acquiring device according to embodiments of the present disclosure
includes a yarn information acquiring section that, when yarn formed with a sliver
in one can is wound to form a plurality of packages in a yarn winding machine, acquires
yarn information indicating a state of the yarn by the can.
[0019] With this yarn information acquiring device, yarn information is acquired on a can-by-can
basis, and thus if some event occurs due to a certain can in a package in a subsequent
process, the cause of occurrence of the event can be easily identified.

winding section that winds the yarn and forms a package; and the yarn information
acquiring device described above.
[0022] With the yarn winding machine and the textile machine system, the yarn information
acquiring device described above is provided therein, and thus if some event occurs
in a package in a subsequent process after the process of forming the package, the
cause of occurrence of the event can be easily identified.
[0023] According to the present disclosure, it is possible to provide the yarn information

DETAILED DESCRIPTION
[0025] An embodiment of the present disclosure will now be described in detail with reference
to the drawings. In the drawings, like or equivalent elements are designated by like
numerals, and duplicate description is omitted.
[0026] As depicted in FIG. 1, a yarn winding machine 1 includes a plurality of yarn winding
units 2, a plurality of unit control devices 3, and a machine control device (yarn
information acquiring device) 4. The yarn winding machine 1 is an automatic winder.
Each yarn winding unit 2 winds yarn to form a package. Each unit control device 3
is provided for every certain number of yarn winding units 2, and controls operation
of the yarn winding units 2 under management thereof. The machine control device 4
communicates with each unit control device 3 to control operation of the yarn winding
machine 1.
[0027] The unit control devices 3 and the machine control device 4 are each configured as
a computer device including a processor, a memory, a storage, and a communication
device. In each control device, the processor executes predetermined software (program)
read in the memory, for example, reads and writes data in the memory and the storage,
and controls communication between the control devices performed by the communication
device, whereby functions of the respective control devices described later are implemented.
Each unit control device 3 may be provided for every yarn winding unit 2.
[0028] As depicted in FIG. 2, each yarn winding unit 2 includes a yarn supplying section
21, a tension applying section 22, a tension detecting section 23, a yarn monitoring
section 24, a joining section 25, and a winding section 26.
[0029] The yarn supplying section 21 supplies yarn. The yarn supplying section 21 includes
a bobbin supporting device that supports a yarn supplying bobbin. The tension applying
section 22 applies tension to yarn travelling from the yarn supplying section 21 toward
the winding section 26. The tension applying section 22 is a gate-type tension applying
device or a disk-type tension applying device, for example. The tension detecting
section 23 detects tension generated in yarn when the yarn is wound. Based on the
tension detected by the tension detecting section 23, the unit control device 3 feedback-controls
a command value to be input to the tension applying section 22 such that the tension
applied to yarn by the tension applying section 22 becomes a target value.
[0030] The yarn monitoring section 24 monitors the yarn travelling from the yarn supplying
section 21 toward the winding section 26 to detect a yarn defect. The yarn monitoring
section 24 includes a detection device 24a and a control device 24b. The detection
device 24a is, for example, an optical sensor that emits light to yarn and detects
temporal change in thickness of the yarn on the basis of change in amount of received
light or a capacitive sensor that causes yarn to pass through an electric field and
detects temporal change in fiber volume (thickness) of the yarn on the basis of change
in capacitance. The detection device 24a outputs a waveform signal indicating temporal
change in yarn thickness or fiber volume to the control device 24b. Based on the waveform
signal, the control device 24b calculates yarn defect information indicating the length
and the thickness or the fiber volume of the yarn defect in the yarn, and outputs
the yarn defect information to the unit control device 3. If the unit control device
3 has determined based on the yarn defect information that the yarn defect needs to
be removed, the yarn is cut by, for example, a cutter provided to the yarn winding
unit 2. The yarn monitoring section 24 can also detect the speed of the yarn travelling
from the yarn supplying section 21 toward the winding section 26, a foreign matter
contained in the yarn, and yarn breakage, for example.
[0031] When the yarn has been cut in order to remove a yarn defect detected by the yarn
monitoring section 24 or yarn breakage has been detected by the yarn monitoring section
24, the joining section 25 performs joining operation of joining the yarn on the yarn
supplying section 21 side and the yarn on the winding section 26 side. The joining
section 25 includes a first yarn catching-and-guiding device, a second yarn catching-and-guiding
device, and a joining part. The first yarn catching-and-guiding device catches the
yarn on the yarn supplying section 21 side by suction, and guides the yarn to the
joining part. The second yarn catching-and-guiding device catches the yarn on the
winding section 26 side by suction, and guides the yarn to the joining part. The joining
part is, for example, a splicer using compressed air, a piecer using a seed yarn,
or a knotter that mechanically joins yarns, and joins the yarns thus guided.
[0032] The winding section 26 winds yarn around a bobbin to form a package. The winding
section 26 includes a cradle arm, a winding drum, and a traverse device. The cradle
arm rotatably supports the package. The winding drum comes into contact with a surface
of the package supported by the cradle arm to rotate the package. The traverse device
traverses the yarn by a predetermined width with respect to the rotating package.
When a motor directly drives and rotates the package, the winding drum may have a
traverse groove, for example.
[0033] As depicted in FIG. 3, the machine control device 4 includes a processing section
(yarn information acquiring section) 41 and a storage section (yarn information storage
section) 42.
[0034] When yarn is wound to form a package in the yarn winding machine 1, the processing
section 41 acquires each of yarn information, environmental information, and operating
information, and manages each of the yarn information, the environmental information,
and the operating information by the package (i.e., in a manner associated with individual
packages). The yarn information is information indicating a state of yarn (state of
yarn travelling from the yarn supplying section 21 toward the winding section 26).
The environmental information is information indicating at least one of temperature
and humidity in an area where the yarn winding machine 1 is installed. The operating
information is information indicating at least one of an operating condition and an
operating state of the yarn winding machine 1.
[0035] The processing section 41 acquires each of the yarn information, the environmental
information, and the operating information for each of divided yarn lengths . The
divided yarn lengths are a plurality of lengths into which a fully wound yarn length
in a package fully wound is divided (i.e., the length of yarn that forms one complete
package). Specifically, the divided yarn lengths are lengths into which the fully
wound yarn length is divided by a value within a range equal to or larger than 10
and equal to or smaller than 1000. Herein, the fully wound yarn length is equally
divided. In other words, the yarn lengths (divided yarn lengths) of the respective
segments after division are equal to each other.
[0036] When one package is formed with a plurality of yarn supplying bobbins, the processing
section 41 acquires each of the yarn information, the environmental information, and
the operating information by the yarn supplying bobbin (i.e., in a manner associated
with individual yarn supplying bobbins) . When yarn is wound to form a package in
the yarn winding machine 1, the processing section 41 acquires event information indicating
an event (e.g., joining performed by the joining section 25, sudden tension change
detected by the tension detecting section 23, correction for a value detected by the
tension detecting section 23 such as temperature correction) that has occurred in
the yarn and also time information (time when the event has occurred). The processing
section 41 also acquires winding start time and winding end time for each package.
The processing section 41 acquires pieces of information described above from each
unit control device 3.
[0037] The storage section 42 stores each of the yarn information, the environmental information,
and the operating information acquired by the processing section 41 on a package-by-package
basis (i.e., in a manner associated with individual packages) and for each divided
yarn length. When one package is formed with a plurality of yarn supplying bobbins,
the storage section 42 stores each of the yarn information, the environmental information,
and the operating information on a yarn supplying bobbin-by-yarn supplying bobbin
basis (i.e., in a manner associated with individual yarn supplying bobbins) . The
storage section 42 also stores the event information with the time information. The
storage section 42 stores winding start time and winding end time for each package.
[0038] As one example as depicted in FIG. 4, the processing section 41 acquires pieces of
information (first yarn information) indicating tension strength, speed, and tension
for each of divided yarn lengths (first yarn lengths) into which the fully wound yarn
length is equally divided by 100, and the storage section 42 stores these pieces of
information. The tension strength is an average value of command values that are input
to the tension applying section 22 of each yarn winding unit 2 by the corresponding
unit control device 3. The speed is an average value of speeds of yarn travelling
from the yarn supplying section 21 toward the winding section 26, and is detected
by the yarn monitoring section 24 of the yarn winding unit 2. The tension is an average
value of tensions that are generated in yarn when the yarn is wound, and is detected
by the tension detecting section 23. In FIG. 4, the left ordinate represents values
of the tension strength and the speed, and the right ordinate represents values of
the tension.
[0039] As depicted in FIG. 5, the processing section 41 acquires pieces of information (second
yarn information) indicating thickness, hairiness quantity, uniformity, a residual
yarn defect (A1), a residual yarn defect (Thin), a residual yarn defect (Thick), and
a residual yarn defect (Nep) for each of divided yarn lengths (second yarn lengths
that are longer than the first yarn lengths) into which the fully wound yarn length
is equally divided by 20, and also acquires information (environmental information)
indicating temperature. The storage section 42 stores these pieces of information.
The thickness is an average value of yarn thicknesses (apparent thicknesses), and
is detected by the yarn monitoring section 24 of each yarn winding unit 2. The hairiness
quantity is an average value of yarn hairiness quantities, and is detected by the
yarn monitoring section 24. The uniformity is an average value of yarn uniformities,
and is detected by the yarn monitoring section 24. The residual yarn defect (A1) is
the number of A1-class yarn defects that have not been removed, and is detected by
the yarn monitoring section 24 of the yarn winding unit 2. The residual yarn defect
(Thin) is the number of thin-yarn defects that have not been removed, and is detected
by the yarn monitoring section 24 of the yarn winding unit 2. The residual yarn defect
(Thick) is the number of thick-yarn defects that have not been removed, and is detected
by the yarn monitoring section 24 of the yarn winding unit 2. The residual yarn defect
(Nep) is the number of yarn defects corresponding to neps that have not been removed,
and is detected by the yarn monitoring section 24 of the yarn winding unit 2. Each
of the residual yarn defect (A1), the residual yarn defect (Thin), the residual yarn
defect (Thick), and the residual yarn defect (Nep) is a value obtained by converting
the number thereof detected for each of divided yarn lengths into which the fully
wound yarn length is equally divided by 20 into the number thereof for a predetermined
length (e.g., 100 kilometers). The temperature is an average value of temperatures
in an area where the yarn winding machine 1 is installed, and is detected by a temperature
sensor (not depicted). In FIG. 5, the left ordinate represents values of the thickness,
the hairiness quantity, the uniformity, the residual yarn defect (A1), the residual
yarn defect (Thin), the residual yarn defect (Thick), and the residual yarn defect
(Nep), and the right ordinate represents values of the temperature.
[0040] As depicted in FIG. 6, the processing section 41 acquires pieces of information (operating
information indicating operating states of the yarn winding machine 1) indicating
an A-axis average, an A-axis maximum, a B-axis average, and a B-axis maximum of vibrations
of the yarn winding unit 2 for each of divided yarn lengths into which the fully wound
yarn length is equally divided by 100, and also acquires information (operating information
indicating an operating condition of the yarn winding machine 1) indicating rotation
speed of a package. The storage section 42 stores these pieces of information. The
A-axis average is an average value of vibrations in an A-axis direction, and is detected
by an acceleration sensor attached to the unit control device 3, for example. The
A-axis maximum is a maximum value of vibrations in the A-axis direction, and is detected
by an acceleration sensor attached to the unit control device 3, for example. The
B-axis average is an average value of vibrations in a B-axis direction, and is detected
by an acceleration sensor attached to the unit control device 3, for example. The
B-axis maximum is a maximum value of vibrations in the B-axis direction, and is detected
by an acceleration sensor attached to the unit control device 3, for example. The
rotation speed is a rotation speed of a package that is being wound, and is detected
by a rotation speed sensor, for example. In FIG. 6, the left ordinate represents values
of the A-axis average, the A-axis maximum, the B-axis average, and the B-axis maximum,
and the right ordinate represents values of the rotation speed.
[0041] As described in the foregoing, the machine control device 4 includes the processing
section 41 that, when yarn is wound to form a package in the yarn winding machine
1, acquires yarn information indicating a state of the yarn. The processing section
41 manages the yarn information by the package, and acquires the yarn information
for each of divided yarn lengths that are a plurality of lengths into which a fully
wound yarn length in the package fully wound is divided. In the machine control device
4, the yarn information is acquired for each divided yarn length to be managed on
a package-by-package basis as described above, and thus if some event occurs in a
package in a subsequent process after a process of forming the package, the cause
of occurrence of the event can be easily identified. This applies to the yarn winding
machine 1 including the machine control device 4.
[0042] The machine control device 4 further includes the storage section 42 that stores
the yarn information indicating the state of the yarn by the package and for each
divided yarn length. By this configuration, the cause of occurrence of an event that
occurs in a package can be identified in the machine control device 4.
[0043] In the machine control device 4, the divided yarn lengths are lengths into which
the fully wound yarn length is divided by a value within the range equal to or larger
than 10 and equal to or smaller than 1000. By this setting, even with a limited storage
capacity (memory), temporal change of the yarn information can be acquired in an identifiable
manner (in a visualized manner) while the memory is being efficiently used.
[0044] In the machine control device 4, the processing section 41 acquires the first yarn
information for each first yarn length, and acquires the second yarn information that
is different from the first yarn information for each second yarn length that is different
from the first yarn length. While the pattern of temporal change of yarn information
to be acquired is being focused on, the number of divisions is reduced (i.e., the
divided yarn length is increased) for yarn information temporal change of which is
small, whereby the amount of yarn information acquired for one package can be reduced.
Thus, even with a limited storage capacity (memory), the number of types of yarn information
to be acquired can be increased. Thus, the divided yarn length for acquiring yarn
information can be set from the viewpoint of temporal changes, and temporal changes
of respective pieces of yarn information of various types can be acquired in an identifiable
manner (each in a visualized manner) while the memory is being efficiently used.
[0045] In the machine control device 4, the processing section 41 acquires information indicating
tension generated in yarn when the yarn is wound as the first yarn information for
each first yarn length, and acquires information indicating thickness of the yarn
as the second yarn information for each second yarn length that is longer than the
first yarn length. By this configuration, change in tension and change in the thickness
of yarn that are pieces of important information for grasping quality of a package
can be acquired such that each change can be identified (each in a visualized manner)
while the memory is being efficiently used.
[0046] In the machine control device 4, the processing section 41 acquires environmental
information indicating at least one of temperature and humidity in an area where the
yarn winding machine 1 is installed, for each of divided yarn lengths into which the
length of yarn that forms one package is divided. By this configuration, whether at
least one of the temperature and the humidity is concerned as a cause of occurrence
of an event that occurs in a package can be analyzed.
[0047] In the machine control device 4, the processing section 41 acquires operating information
indicating at least one of an operating condition and an operating state of the yarn
winding machine 1, for each of divided yarn lengths into which the length of yarn
that forms one package is divided. By this configuration, whether at least one of
the operating condition and the operating state is concerned as a cause of occurrence
of an event that occurs in a package can be analyzed.
[0048] In the machine control device 4, when each package is formed with a plurality of
yarn supplying bobbins, the processing section 41 acquires the yarn information indicating
the state of the yarn by the yarn supplying bobbin. By this configuration, whether
a certain yarn supplying bobbin is concerned as a cause of occurrence of an event
that occurs in a package can be analyzed.
[0049] In the machine control device 4, the processing section 41 acquires event information
indicating an event that occurs in the yarn together with time information when the
yarn is wound to form the package in the yarn winding machine 1. By this configuration,
whether an event that occurs in yarn when a package is formed is concerned as a cause
of occurrence of an event that occurs in the package can be analyzed. In particular,
when information indicating joining of yarn is acquired as the event information together
with the time information, whether joining of yarn is concerned as a cause of occurrence
of the event that occurs in the package can be analyzed.
[0050] The types of pieces of information to be acquired and stored can be changed by mode
setting. By changing the types of pieces of information to be acquired and stored
depending on purposes, the minimum necessary amount of information can be acquired
and stored. Depending on the number of joining operations, the number of residual
yarn defects, or the like, the quality of each package can be evaluated. By checking,
for a plurality of packages, pieces of information on catching of yarn on the winding
section 26 side performed by the second yarn catching-and-guiding device, catching
positions depending on diameters of the packages (positions where the second yarn
catching-and-guiding device stops to catch the yarn on the winding section 26 side)
can be optimized. By checking the speed of yarn with respect to wound lengths, variations
in adjustment of the angle of the cradle arm in the winding section 26 can be grasped.
By utilizing event information (information indicating an event that occurs in yarn)
together with time information, change in quality data when a certain alarm is issued
can be grasped, whereby the abnormality location in the yarn winding machine 1 can
be easily identified.
[0051] Although one embodiment of the present disclosure has been described above, the present
disclosure is not limited to the embodiment.
[0052] The yarn winding machine 1 is not limited to the automatic winder, and may be an
air spinning machine, an open-end spinning machine, or a ring spinning machine, for
example. When the yarn winding machine 1 is an air spinning machine, for example,
each yarn winding unit 2 does not include the tension applying section 22, but further
includes a yarn storage device that stores yarn and a waxing device that applies wax
to the yarn. When the yarn winding machine 1 is the air spinning machine, each yarn
supplying section 21 includes a drafting device that drafts a fiber band and an air
spinning device that generates yarn by twisting the drafted fiber band using swirling
airflow. When the yarn winding machine 1 is a spinning machine, the joining section
25 may be configured as a joining carrier that can travel with respect to the yarn
winding units 2.
[0053] For example, when the yarn winding machine 1 is the spinning machine and one package
is formed with at least one can (sliver can), the yarn information indicating the
state of yarn may be acquired on a can-by-can basis. By this setting, whether a certain
can is concerned as a cause of occurrence of an event that occurs in a package can
be analyzed.
[0054] The speed of yarn travelling from the yarn supplying section 21 toward the winding
section 26 is not limited to that detected by the yarn monitoring section 24, and
may be detected by a speed sensor provided separately, or may be calculated based
on the rotation speed of the winding drum in the winding section 26. When the yarn
winding machine 1 is the air spinning machine, the speed of the corresponding yarn
may be calculated based on a speed at which the air spinning machine forms yarn.
[0055] In the embodiment, the machine control device 4 includes the processing section 41
having a function as the yarn information acquiring section and the storage section
42 having a function as the yarn information storage section. However, the yarn information
acquiring device, the yarn winding machine, and the textile machine system according
to the present disclosure are not limited to this. For example, each unit control
device (yarn information acquiring device) 3 may include the yarn information acquiring
section, and the machine control device 4 may include the yarn information storage
section. Alternatively, each unit control device (yarn information acquiring device)
3 or the machine control device (yarn information acquiring device) 4 may include
the yarn information acquiring section, and a management device that is a host control
device of the yarn winding machine 1 may include the yarn information storage section.
Alternatively, each unit control device (yarn information acquiring device) 3, the
machine control device (yarn information acquiring device) 4, or the management device
(yarn information acquiring device) that is a host control device of the yarn winding
machine 1 may include the yarn information acquiring section, and a management device
located in another place may include the yarn information storage section.
[0056] For example, when the management device that is a host control device of the yarn
winding machine 1 functions as the yarn information acquiring device, the yarn winding
machine 1 and the management device may constitute a textile machine system. With
the textile machine system thus configured, if some event occurs in a package in a
subsequent process after a process of forming the package, the cause of occurrence
of the event can be easily identified.
[0057] The yarn information acquiring device such as the unit control device 3, the machine
control device 4, or the management device that is a host control device of the yarn
winding machine 1 may include a yarn information acquiring section that, when yarn
formed with a sliver (fiber band) in one can is wound to form a plurality of packages
in the yarn winding machine 1, acquires yarn information indicating a state of the
yarn by the can. With the yarn information acquiring device thus configured, the yarn
information is acquired on a can-by-can basis, and thus if some event occurs due to
a certain can in a package in a subsequent process, the cause of occurrence of the
event can be easily identified.
[0058] The number by which the length of yarn to form one package is divided may be optionally
set depending on the yarn information. Specifically, the divided yarn lengths are
not limited to the lengths into which the fully wound yarn length is divided by a
value within the range equal to or larger than 10 and equal to or smaller than 1000,
and may be lengths into which the fully wound yarn length is divided by a value outside
the range equal to or larger than 10 and equal to or smaller than 1000. Values of
the yarn information, the environmental information, and the operating information
to be acquired for each divided yarn length may be optionally set to average values,
maximum values, minimum values, median values, or cumulative values, for example,
depending on the yarn information.
[0059] The yarn information acquiring device such as the unit control device 3, the machine
control device 4, or the management device that is a host control device of the yarn
winding machine 1 may include a display unit that displays pieces of yarn information
acquired for each divided yarn length. Pieces of yarn information acquired for each
divided yarn length may be displayed as trend data on a package-by-package basis by
the display unit as depicted in FIG. 4 and FIG. 5.
[0060] The yarn information acquiring device such as the unit control device 3, the machine
control device 4, or the management device that is a host control device of the yarn
winding machine 1 may include a setting section that sets a fully wound yarn length.
The fully wound yarn length is set generally to a length equal to or greater than
100 kilometers, and is set to, depending on yarn count, for example, about 200 kilometers
for medium count yarn (e.g., Ne 40) and about 300 to 500 kilometers for fine count
yarn (e.g., Ne 100). For example, the fully wound yarn length of a package is order-of-magnitudes
longer than the fully wound yarn length of a yarn supplying bobbin that is about 4
kilometers for medium count yarn. With the yarn information acquiring device, the
yarn winding machine, and the textile machine system according to the present disclosure,
the yarn information of a package the fully wound yarn length of which is very long
as described above can be efficiently and appropriately acquired and managed.
[0061] For example, when the maximum value or the minimum value of optionally selected yarn
information is to be acquired, the yarn information acquiring device such as the unit
control device 3, the machine control device 4, or the management device that is a
host control device of the yarn winding machine 1 may acquire the maximum value or
the minimum value of the yarn information for each divided yarn length by temporarily
storing a maximum value or a minimum value in the current divided yarn length segment
from the time when the current divided yarn length segment starts while updating the
maximum value or the minimum value as necessary, and determining the value at the
time when the current divided yarn length segment ends. For example, when the cumulative
value of optionally selected yarn information is to be acquired, the yarn information
acquiring section may acquire the cumulative value of the yarn information for each
divided yarn length by temporarily stores a cumulative value in the current divided
yarn length segment from the time when the current divided yarn length segment starts
while updating the cumulative value as necessary, and determining the value at the
time when the current divided yarn length segment has ended. Acquiring the yarn information
by such methods as described above eliminates the need of storing raw data, and thus
the memory can be efficiently used. Alternatively, the yarn information acquiring
section may continue to temporarily store pieces of raw data in a predetermined divided
yarn length segment from when the divided yarn length segment starts to when the segment
ends, may calculate the average value or the median value, for example, based on the
pieces of raw data at the time when the predetermined divided yarn length segment
has ended, and may discard the raw data after the calculation. By this method, the
need of storing raw data that is relatively large data can be minimized, and an appropriate
value can be obtained while the memory is being efficiently used.
[0062] Based on the embodiment described above, a yarn information acquiring device, a yarn
winding machine, and a textile machine system according to the present disclosure
can be obtained as follows.
[0063] A yarn information acquiring device according to the present disclosure includes
a yarn information acquiring section that, when yarn is wound to form a package in
a yarn winding machine, acquires yarn information indicating a state of the yarn by
the package.
[0064] With this yarn information acquiring device, the yarn information is acquired on
