TECHNICAL FIELD
[0001] The present disclosure relates to a textile machine, a
management device, a yam winding system, and a managing method.
BACKGROUND
[0002] A system configured to display a work plan and production
progress, for example, based on an operation schedule in a spinning
plant is known (see Japanese Unexamined Patent Publication No.
H4-202816, for example).
SUMMARY
[0003] In such a conventional yarn winding system, an operator needs
to check the production progress, and then the operator needs to adjust
the production speed based on the work plan. Adjustment of the
production speed can be a work burden on the operator.
[0004] It is an object of one aspect of the present disclosure to provide a
textile machine, a management device, a yarn winding system, and a
managing method that enable reduction in workload of adjusting the
production speed.
[0005] A textile machine according to one aspect of the present
disclosure is a textile machine configured to wind yarn to form a
package, the textile machine including: an acquisition section
configured to acquire production plan information on a production plan
of the package and production state information on a current production
state of the package; a calculation section configured to calculate a
progress status on production of the package based on the production
plan information and the production state information acquired by the
acquisition section; and a setting section configured to change a setting
of winding speed of the yarn based on the progress status calculated by
5 the calculation section.
[0006] In the textile machine according to this aspect of the present
disclosure, the progress status is calculated based on the production plan
information and the production state information, and the winding speed
of yam is changed based on the progress status. By changing the
winding speed of yarn, the production speed of a package produced in
the textile machine can be adjusted. In the textile machine, the
winding speed of yarn can be automatically changed based on the
progress status as described above, and thus a workload of adjusting the
production speed can be reduced.
[0007] In one embodiment, the acquisition section may be adapted to
acquire the production state information that contains at least one of
actual production quantity of the package and actual production
efficiency of the package. With this configuration, the production state
can be accurately determined.
[0008] In one embodiment, the textile machine may include an input
section configured to receive input of an upper limit and a lower limit of
the winding speed, and the setting section may be adapted to change the
setting of the winding speed within a range between the upper limit and
the lower limit input in the input section. The upper limit and the
lower limit of the winding speed can be set such that the quality of yam
is maintained within a certain range. Thus, by changing the winding
speed within the range between the upper limit and the lower limit of
the winding speed, variation in yarn quality during formation of a
package can be reduced.
[0009] In one embodiment, the textile machine may include an input
section configured to receive input of a reference value of the winding
speed, and the setting section may be adapted to set an allowable range
of the winding speed including the reference value and to change the
setting of the winding speed only within the allowable range. The
allowable range can be set such that the quality of yarn is maintained
within a certain range. Thus, by changing the winding speed within
the allowable range, variation in yam quality during formation of a
package can be reduced.
[0010] In one embodiment, the acquisition section may be adapted to
acquire the production plan information that contains at a least target
production quantity of the package and a production schedule of the
package. With this configuration, based on the target production
quantity and the production schedule of the package, the calculation
section can calculate the progress status accurately.
[0011] In one embodiment, the setting section may be adapted to
change the setting of the winding speed such that the winding speed
becomes faster than an initial value of the winding speed set based on
the production plan information when the progress status is behind a
scheduled status. With this configuration, the production plan can be
reliably accomplished.
[0012] In one embodiment, the setting section may be configured not to
change the setting of the winding speed when the progress status is
ahead of a scheduled status. With this configuration, the production
plan can be reliably accomplished, and also variation in yarn quality
during formation of a package can be reduced.
[0013] In one embodiment, the acquisition section may be adapted to
acquire a progress status of another textile machine, and the setting
section may be adapted to change the setting of the winding speed of the
yam based on the progress status calculated by the calculation section
and the progress status of the other textile machine acquired by the
acquisition section. With this configuration, for example, when the
progress status of the other textile machine is behind its scheduled
status, increasing the winding speed of yarn can compensate for
production delay in the other textile machine.
[0014] In one embodiment, the textile machine may further include: a
yarn feeder configured to support a yam feeding bobbin around which
the yam is wound; and a winding device configured to wind the yarn
unwound from the yarn feeding bobbin supported by the yarn feeder to
form a package. When the above-described textile machine is
configured as an automatic winder, the workload of an operator in
adjusting the production speed can be reduced.
[0015] A management device according to one aspect of the present
disclosure is a management device configured to manage one or a
plurality of textile machines each configured to wind yam to form a
package, the management device including: an acquisition section
configured to acquire production plan information on a production plan
of the packages for the textile machines and production state
information on a current production state of the package produced in
each textile machime; a calculation section configured to calculate a
progress status on production of the package in the textile machine
based on the production plan information and the production state
information acquired by the acquisition section; a setting section
configured to change a setting of the textile machine based on the
progress status calculated by the calculation section; and a transmission
section configured to transmit setting information on the setting
changed by the setting section to the textile machime, wherein when the
number of the textile machines is one, the setting section is adapted to
change a setting of a winding speed of the yarn based on the progress
status, and when the number of the textile machines is more than one,
the setting section is adapted to change a setting of at least one of a
winding speed of the yam in each textile machine and target production
quantity of the packages in each textile machine based on the progress
status.
[0016] In the management device according to this aspect of the present
disclosure, the progress status is calculated based on the production plan
information and the production state information. If the number of the
textile machines is one, the setting of the winding speed of yam is
changed based on the progress status, and if the number of the textile
machines is more than one, the setting of at least one of the winding
speed of the yam and the target production quantity of the packages in
each textile machine is changed based on the progress status. In the
management device, the settings of the winding speed of yam in each
textile machine and the production quantity of the packages can be
automatically changed based on the progress status as described above,
and thus the workload of adjusting the production speed can be reduced.
[0017] In one embodiment, the acquisition section may be adapted to
acquire the production state information that contains at least one of
actual production quantity of the package and actual production
efficiency of the package. With this configuration, the production state
can be accurately determined.
[0018] In one embodiment, the management device may include an
input section configured to receive input of an upper limit and a lower
limit of the winding speed, and the setting section may change the
setting of the winding speed within a range between the upper limit and
the lower limit input in the input section. The upper limit and the
lower limit of the wind& speed can be set such that the quality of yarn
is maintained within a certain range. Thus, by changing the winding
speed within the range between the upper limit and the lower limit of
the winding speed, variation in yarn quality during formation of a
package can be reduced.
[0019] In one embodiment, the management device may include an
input section configured to receive input of a reference value of the
winding speed, and the setting section may set an allowable range of the
winding speed including the reference value and change the setting of
the windmg speed within the allowable range. The allowable range
can be set such that the quality of yarn is maintained within a certain
range. Thus, by changing the winding speed within the allowable
range, variation in yarn quality during formation of a package can be
reduced.
[0020] In one embodiment, the acquisition section may acquire the
production plan information that contains at least target production
quantity of the package and a production schedule of the package.
With this configuration, based on the target production quantity and the
production schedule of the package, the calculation section can calculate
the progress status accurately.
[0021] In one embodiment, the setting section may change the setting
of the winding speed such that the winding speed becomes faster than
an initial value of the winding speed set based on the production plan
information when the progress status is behind a scheduled status.
With this configuration, the production plan can be reliably
accomplished.
[0022] In one embodiment, the setting section does not change the
setting of the winding speed when the progress status is ahead of a
scheduled status. With this configuration, the production plan can be
reliably accomplished, and also variation in yam quality during
formation of a package can be reduced.
[0023] In one embodiment, when the number of the textile machines is
more than one and the progress status is different from each other
between the textile machines, the setting section may be adapted to
change the settings of the target production quantities of the respective
textile machines such that the target production quantity assigned to the
textile machine the progress of which is slow is assigned to the textile
machine the progress of which is fast. With this configuration, even
when there is a textile machine in which production of the package is
delayed, this production delay can be compensated for by another textile
machine. Furthermore, by assigning the production quantity to the
other textile machine, the amount of change in winding speed can be
reduced. Particularly when the number of the textile machines is
larger, the amount of change in winding speed for each textile machine
can be further reduced, and influence of the change in winding speed
5 upon the yarn quality can be further reduced.
[0024] A yam winding system according to one aspect of the present
disclosure is a yam winding system including a plurality of textile
machines each configured to wind yarn to form a package and a
management device configured to manage the textile machines, wherein
10 the management device includes: an acquisition section configured to
acquire production plan information on a production plan of the
packages for the textile machines and production state information on a
current production state of the package in each textile machine; a
calculation section configured to calculate a progress status on
production of the package in each textile machine based on the
production plan information and the production state information
acquired by the acquisition section; a setting section configured to
change a setting of at least one of a winding speed of the yarn in each
textile machine and target production quantity of the packages in each
textile machine based on the progress status calculated by the
calculation section; and a transmission section configured to transmit at
least one of speed information on the winding speed and production
quantity information on the target production quantity changed by the
setting section to each textile machine, and each textile machine
comprises: a receiving section configured to receive at least one of the
speed information and the production quantity information transmitted
kom the transmission section of the management device; and an
operation controller configured to control operation of the textile
machine based on at least one of the speed information and the
production quantity information received by the receiving section.
[0025] In the yam winding system according to this aspect of the
present disclosure, the progress status is calculated based on the
production plan information and the production state information, and
the setting of at least one of the winding speed of yam and the
production quantity of the packages is changed based on the progress
status. In the yam winding system, the winding speed of yarn in each
textile machine and the production quantity of the packages can be
automatically changed based on the progress status as described above,
and thus the workload of adjusting the production speed can be reduced.
[0026] In one embodiment, when the receiving section has received the
speed information, the operation controller may be adapted to control
operation of the textile machine so as to wind the yarn at the winding
speed in accordance with the speed information. With this
configuration, in the textile machine, the yarn can be wound at the
changed winding speed.
[0027] In one embodiment, when the progress status is different
between the textile machines, the setting section may be adapted to
change the settings of the target production quantities of the respective
textile machines such that the target production quantity assigned to the
textile machine progress of which is slow is assigned to the textile
machine the progress of which is fast. With this configuration, even
when there is a textile machine in which production of the package is
delayed, this production delay can be compensated for by another textile
machine. Furthermore, by assigning the production quantity to the
other textile machine, the amount of change in winding speed can be
reduced. Particularly when the number of the textile machines is
5 larger, the amount of change in winding speed for each textile machine
can be further reduced, and influence of the change in winding speed
upon the yam quality can be further reduced.
[0028] In one embodiment, the setting section may be adapted to
change the target production quantity with a higher priority than
changing the winding speed. With this configuration, by giving a
higher priority to changing the target production quantity (redistribution
of the target production quantity), the amount of change in winding
speed can be reduced. Thus, influence of the change in winding speed
upon the yarn quality can be reduced.
[0029] In one embodiment, when production cannot be completed
within a production period that a production schedule indicates only by
changing the target production quantity, the setting section may be
adapted to change the setting of the winding speed of each textile
machine. With this configuration, the production plan can be reliably
accomplished.
[0030] A managing method according to one aspect of the present
disclosure is a managing method for managing a plurality of textile
machines each winding yam to form a package, the managing method
comprising: an acquisition step of, acquiring production plan
information on a production plan of the packages for the textile
machines and production state information on a current production state
of the package in each textile machine; a calculation step of, calculating
a progress status on production of the package in each textile machine
based on the production plan information and the production state
information acquired at the acquisition step; a setting changing step of,
changing a setting of at least one of a winding speed of the yam in each
textile machine and target production quantity of the packages in each
textile machine based on the progress status calculated at the calculation
step; a transmitting step of, by the management device, transmitting at
least one of speed information on the winding speed and production
quantity information on the target production quantity changed at the
setting changing step to each textile machine; a receiving step of, by
each textile machine, receiving at least one of the speed information and
the production quantity information transmitted at the transmitting step;
and an operation controlling step of, by each textile machine,
controlling operation of the textile machine based on at least one of the
speed information and the production quantity information received at
the receiving step.
[0031] In the managing method according to this aspect of the present
disclosure, the progress status may be calculated based on the
production plan information and the production state information, and
the setting of at least one of the winding speed of yam and the target
production quantity of the packages in each textile machine may be
changed based on the progress status. In the managing method, the
winding speed of yarn in each textile machine and the target production
quantity of the packages in each textile machine can be automatically
changed based on the progress status as described above, and thus the
workload of adjusting the production speed can be reduced.
[0032] According to one aspect of the present disclosure, a workload of
adjusting the production speed can be reduced.

DETAILED DESCRIPTION
[0034] An embodiment of the present invention will now be described
in detail with reference to the attached drawings. In the description of
the drawings, like or equivalent elements are designated by like
numerals, and duplicate description is omitted.
[0035] As depicted in FIG. 1, the yarn winding system 1 includes a
management device 3 and a textile machine 5. In the yam winding
system 1 in the present embodiment, the textile machine 5 is provided in
plurality.
[0036] The management device 3 manages the textile machines 5 in a
centralized manner. The management device 3 includes a central
processing unit (CPU), a read only memory (ROM), a random access
memory (RAM), and an input/output port, which are not depicted.
The ROM stores therein a program for controlling the textile machines
5. The CPU can perform processing for controlling the textile
machines 5 by reading the program stored in the ROM into the RAM
and executing the program. The management device 3 is connected to
the textile machines 5 so as to be able to communicate therewith via
wireless and/or wired communication.
[0037] In the present embodiment, each textile machine 5 is an
automatic winder. As depicted in FIG. 2, the textile machine 5
includes a plurality of winding units 6 disposed in parallel, a machine
control device (operation controller) 7, and a doffer 8.
[0038] Each winding unit 6 unwinds yam Y from a yam feeding bobbin
SB, and simultaneously winds the yam Y around a winding bobbin WB
while traversing the yam. In this manner, the winding unit 6 forms a
package P. The winding unit 6 may be configured to unwind yam Y
&om a package P to form a package P.
[0039] The machine control device 7 can communicate with the
management device 3 and the respective winding units 6. An operator
of the textile machine 5 can manage the winding units 6 in a collective
manner by appropriately operating the machine control device 7. The
machine control device 7 includes a display screen 7a and input keys
7b. The display screen 7a can display, for example, information on
settings and/or the states of the winding units 6. The operator can
make the settings of the winding units 6 by performing appropriate
operations with the input keys 7b.
[0040] The machine control device 7 includes a communication section
(receiving section) 7c. The communication section 7c transmits and
receives information (data) to and &om the management device 3. The
machine control device 7 transmits production state information
including information on the actual production quantity of packages P
formed by the winding units 6 and information on the current
production efficiency of the packages P to the management device 3 via
the communication section 7c. The production efficiency is a
production quantity of packages P per unit time. The information
indicating the production quantity of packages P and the information
indicating the production efficiency can be acquired based on the
number of packages P processed by the doffer 8, for example. Timing
when the machine control device 7 transmits the production state
information to the management device 3 may be every time doffmg is
performed, may be at predetermined time intervals, or may be at all
times.
[0041] The machine control device 7 receives, at the communication
section 7c, production quantity information (described later) and speed
information transmitted from the management device 3. The machine
control device 7 controls operations of the respective winding units 6 on
the basis of the production quantity information received at the
communication section 7c. Specifically, based on the production
quantity information, the machine control device 7 causes the winding
units 6 to form a predetermined number of packages P. The machine
control device 7 also controls the winding speed of yarn Y in each
winding unit 6 on the basis of the speed information. Specifically, the
machine control device 7 outputs information specifying a winding
speed to a unit controller 10 described later.
[0042] When a package P has been fully wound in each winding unit 6
(in a state in which a specified amount of yam is wound), the doffer 8
travels to the position of the corresponding winding unit 6, and removes
the hlly wound package to set an empty winding bobbin WB.
[0043] The following describes a configuration of each winding unit 6
5 with reference to FIG. 3. As depicted in FIG. 3, each winding unit 6
includes the unit controller 10, a yarn feeder 11, and a winding device
12.
[0044] The unit controller 10 controls operation of the winding unit 6.
The unit controller 10 includes a CPU and a ROM, for example. The
10 ROM stores therein a program for controlling the respective
components of the winding unit 6. The CPU executes the program
stored in the ROM.
[0045] The yam feeder 11 is a support mechanism configured to
support a yam feeding bobbin SB placed on a conveying tray (not
15 depicted) at a predetermined position. By this yam feeder, yam Y is
unwound from the yam feeding bobbin SB, and the yam Y is pulled out
from the yarn feeding bobbin SB. In this manner, the yam feeder 11
feeds the yam Y. The type of the yam feeder 11 is not limited to this
conveying tray type, and may be a magazine type, for example. In the
20 case in which a package P is formed from a package P as described
above, the yam feeder 11 may be a support mechanism configured to
support the package P at a predetermined position.
[0046] The winding device 12 includes a cradle 13 and a winding drum
14. The cradle 13 has a pair of rotational-support portions (not
25 depicted). With the rotational-support portions catching a winding
bobbin WB therebetween, the cradle 13 rotatably supports the winding
bobbin WB (or a package P). The cradle 13 can switch states between
a state in which a package P supported thereby is brought into contact
with the winding drum 14 and a state in which the package P is
separated from the winding drum 14.
[0047] The winding drum 14 traverses yarn Y on a surface of a package
P, and also rotates the package P. The winding drum 14 is rotationally
driven by a drum drive motor (not depicted). Operation of the drum
drive motor is controlled by the unit controller 10. By changing the
rotation speed of the winding drum 14, the winding speed of yarn Y can
be changed. Specifically, in the winding unit 6, the unit controller 10
controls the rotation speed of the drum drive motor, thereby controlling
the winding speed of yam Y.
[0048] With the outer periphery of a package P being in contact with
the winding drum 14, the winding drum 14 is rotationally driven,
whereby the package P is rotated in a driven manner. On the outer
peripheral surface of the winding drum 14, a spiral traverse groove is
formed. Yarn Y unwound from the yarn feeding bobbin SB is wound
on a surface of the package P while being traversed at a certain width
along the traverse groove. In this manner, a package P having a certain
winding width can be formed. Herein, a configuration in which a
motor directly rotates the package P may be used, or a configuration in
which the winding drum 14 does not have the traverse groove and a
separate traverse device (e.g., a traverse arm) is provided instead may be
used.
[0049] Each winding unit 6 includes, on a yam traveling path between
the yarn feeder 11 and the winding device 12, in the order of from the
yarn feeder 11 side, an unwinding assisting device 15, a tension
applying device 17, a tension detecting device 18, a splicing device 19,
and a yarn monitoring device 20. Near the splicing device 19, a first
catching-and-guiding device 22 and a second catching-and-guiding
device 23 are disposed.
[0050] The unwinding assisting device 15 includes a restriction
member 16 that can cover a core tube of the yam feeding bobbin SB.
The restriction member 16 has a substantially tubular shape, and is
disposed so as to come into contact with a balloon formed at an upper
portion of a yarn layer of the yarn feeding bobbin SB. Herein, the
configuration of the unwinding assisting device 15 is not limited to this.
[0051] The tension applying device 17 applies a predetermined tension
to traveling yarn Y Operation of the tension applying device 17 is
controlled by the unit controller 10. The tension detecting device 18
detects (measures) the tension of the traveling yarn Y between the yam
feeder 11 and the winding device 12. The tension detecting device 18
outputs a tension measurement signal indicating the tension of the yarn
Y to the unit controller 10.
[0052] When the yarn Y has been cut between the yam feeder 11 and
the winding device 12 for some reason, the splicing device 19 splices
yarn Y (lower yarn) on the yarn feeder 11 side and yarn Y (upper yarn)
on the winding device 12 side. In the present embodiment, the splicing
device 19 is configured as an air-type splicer device that twists yam
ends together using swirling airflow generated by compressed air. The
splicing device 19 may be a disk-type splicer device, may be a piecer
using a seed yarn, or may be a knotter configured to mechanically splice
yams.
[0053] The yam monitoring device 20 monitors the state of yam Y
traveling on a yam path to detect the presence or absence of a yam
defect on the basis of the monitored information. The yam monitoring
device 20 detects, as a yam defect, thickness abnormality of yam Y
andlor foreign matter contained in the yam Y, for example. The yam
monitoring device 20 also detects yam breakage, that is the presence or
absence of yam Y in the yam path, for example. When having
detected a yam defect, the yarn monitoring device 20 outputs a yam
defect detection signal to the unit controller 10. The yarn monitoring
device 20 includes a cutter 21 configured to cut yam Y The cutter 21
is activated by the yam monitoring device 20. The cutter 21 may be
provided near the yam monitoring device 20.
[0054] When yam Y has been cut, the first catching-and-guiding device
22 catches the upper yam. Controlled by the unit controller 10, the
first catching-and-guiding device 22 can rotate (can move) from a
standby position (solid line in FIG. 3) on the yam feeder 11 side to a
catching position (chain line in FIG. 3) on the winding device 12 side.
The first catching-and-guiding device 22 is connected to a
negative-pressure source (not depicted) to generate a suction flow.
With this configuration, the first catching-and-guiding device 22 catches
the upper yam at the catching position and retums to the standby
position, thereby guiding the upper yarn to the splicing device 19.
Herein, the configuration and operation of guiding the upper yam to the
splicing device 19 are not limited to these.
[0055]Controlled by the unit controller 10, the second
catching-and-guiding device 23 rotates &om a standby position (solid
line in FIG. 3) on the yam feeder 11 side to a catching position (dash-dot
line in FIG. 3), which is slightly in fiont of the standby position, and can
further rotate (can move) to a guidance position on the winding device
12 side (dash-dot-dot line in FIG. 3). The second catching-and-guiding
device 23 is connected to a negative-pressure source (not depicted) to
generate a suction flow. With this configuration, the second
catching-and-guiding device 23 catches the lower yam to guide the
lower yam to the splicing device 19. Herein, the configuration and
operation of guiding the lower yam to the splicing device 19 are not
limited to these.
[0056] As described above, the winding unit 6 winds yam Y around the
winding bobbin WE3 to form a package P. For splicing operation in the
splicing device 19, yam Y on the winding device 12 side is caught by
the first catching-and-guiding device 22, and yam Y on the yam feeder
11 side is caught by the second catching-and-guiding device 23. The
yarns Y caught by the frst catching-and-guiding device 22 and the
second catching-and-guiding device 23 are guided to the splicing device
19. At this time, the yams Y are positioned at a slit of the yarn
monitoring device 20. The splicing device 19 splices the yams Y thus
introduced. Herein, the configuration of guiding the yam Y to the
splicing device 19 is not limited to this.
[0057] The following describes the management device 3 in detail. As
depicted in FIG. 4, the management device 3 includes an input section
30, a communication section (transmission section) 32, an acquisition
section 34, a calculation section 36, and a setting section 38.
[0058] The input section 30 receives input of a production plan of
packages P. The input section 30 is a keyboard or a touch panel
display, for example. The production plan contains the production
quantity of a lot (the total weight of packages P or the number of the
packages P), a production schedule (that can include a production
period, or at least one of a production start date and a production
completion data), winding speeds (a reference value, an upper limit, and
a lower limit) of yarn Y, and the number of textile machines 5 to be used
(that may be the number of winding units 6). When the input section
30 is the above-described keyboard, for example, the operator inputs the
production plan in an input screen displayed on a display unit (e.g., a
display or a touch panel display) of the management device 3. The
production plan input in the input section 30 is stored as production plan
information on the production plan in a storage section (not depicted).
The input section 30 may be configured to receive input of the
production plan via a recording medium (e.g., a flash memory or an
HDD) or a network, for example.
[0059] The communication section 32 communicates with the textile
machines 5. The communication section 32 communicates with the
communication section 7c of each textile machine 5 via wireless or
wired communication. The communication section 32 receives the
production state information, which is transmitted from the machine
control device 7 of each textile machine 5, including information
indicating the production quantity of packages P and information
indicating the current production efficiency of the packages P. The
communication section 32 causes the storage section to store therein the
received production state information. The communication section 32
transmits the production quantity information andor the speed
information output from the setting section 38 to the textile machine 5.
[0060] The acquisition section 34 acquires production plan information
on the production plan of packages P and production state information
on the current production state of the packages P. In the present
embodiment, the acquisition section 34 acquires the production plan
information and the production state information from the storage
section. The acquisition section 34 outputs the production plan
information and the production state information thus acquired to the
calculation section 36 and the setting section 38. The acquisition
section 34 may directly acquire the production state information
received by the communication section 32 from the communication
section 32.
[0061] The calculation section 36 calculates a progress status on
production of packages P on the basis of the production plan
information and the production state information acquired by the
acquisition section 34. In the present embodiment, when having
received the production plan information and the production state
information output from the acquisition section 34, the calculation
section 36 calculates a progress rate as the progress status.
[0062] The calculation section 36 calculates the progress rate based on
the number or the weight of packages P scheduled to be produced
obtained from the production plan information, the number or the
weight of packages P that have already been formed in the respective
textile machines 5 obtained from the production state information, and
the production schedule obtained from the production plan information.
Specifically, for example, assuming that the production quantity of
packages P scheduled to be produced is "100", the production quantity
of packages P that have already been formed is "zero", and the
production period is "four days", if "50" packages P should have been
formed at the beginning of "day three" but only "40" packages have
been formed, the calculation section 36 calculates the progress rate as
"80%". Under the above-described assumption, if "60" packages P
have been formed at the beginning of "day three", the calculation
section 36 calculates the progress rate as " 120%".
[0063] The calculation section 36 may also calculate the progress rate
based on the number or the weight of packages P scheduled to be
produced obtained from the production plan information and the
number or the weight of packages P that have already been formed in
the respective textile machines 5 obtained from the production state
information. Specifically, assuming that the production quantity of
packages P scheduled to be produced is "100", if the production quantity
of packages P that have already been formed is "40", the calculation
section 36 calculates the progress rate as "40%".
[0064] The calculation section 36 may calculate the progress rate not
only based on the number of packages P that have already been formed
but also based on information including packages P that have not yet
been formed (that are being wound). For example, the calculation
section 36 preferably counts a package winding of which has been
completed 50% as 0.5 to calculate the progress rate.
[0065] The calculation section 36 outputs progress information
indicating the progress rate thus calculated to the setting section 38.
[0066] The setting section 38 sets the production quantity of packages P
in each textile machine 5. When having received the production plan
information output &om the acquisition section 34, the setting section
38 sets the production quantity (the number or the weight) of packages
P required to be produced in each textile machine 5, that is a target
production quantity for each textile machine 5. Specifically, assuming
that the production quantity of packages P is "100" and the number of
textile machines 5 to be used is "five", for example, the setting section
38 sets the production quantity of packages P required to be produced in
each textile machine 5 as "20". In other words, the setting section 38
makes the setting such that the production quantity of packages P is
evenly assigned to each textile machine 5. The setting section 38 may
also set the production quantity of packages P in each textile machine 5
in accordance with the number of winding units 6 that are operating in
the textile machine 5. As a method of setting the production quantity
by the setting section 38, various methods may be used. The setting
section 38 also sets an initial value of the winding speed of yarn Y on
the basis of the production plan information (the reference value of the
winding speed). The setting section 38 outputs production quantity
information specifying the production quantity set for each textile
machine 5 and initial speed information indicating the initial value of
the winding speed of yam Y to the communication section 32.
[0067] After production of packages P is started in the textile machines
5, the setting section 38 can change the setting of the target production
quantity of packages P in each textile machine 5. Based on the
progress information output from the calculation section 36, the setting
section 38 changes the target production quantity of packages P in each
textile machine 5. When there are variations in progress rate in the
progress information among the textile machines 5, the setting section
38 changes the target production quantity for each textile machine 5.
When there are a textile machine 5 the progress rate of which is high (its
progress is fast) and a textile machine 5 the progress rate of which is
low (its progress is slow), the setting section 38 assigns the target
production quantity assigned to the textile machine 5 the progress rate
of which is low to the other textile machine 5 the progress rate of which
is high. When there are a plurality of textile machines 5 the progress
rates of which are high, the setting section 38 may assign production
quantities evenly to these textile machines 5, or may assign production
quantities depending on their progress rates.
[0068] The setting section 38 outputs setting information (the
production quantity information, the speed information) thus changed to
the communication section 32.
[0069] When the number of textile machines 5 to be used has been
changed, the setting section 38 changes the setting of the target
production quantity of packages P in each textile machine 5. The
number of textile machines 5 when production of packages P is started
may be different from the number of textile machines 5 to be used that
has been input in the input section 30. When production of packages P
is started, the number of the textile machines 5 to be used that has been
input in the input section 30 can include a textile machine 5 that is
producing a package P of another lot. Thus, after the production of
packages P is started, a textile machine 5 in which production of a
package P of another lot has been completed can be added therein.
When the number of textile machines 5 has been changed, the setting
section 38 changes the production quantity of packages P in each textile
machine 5 on the basis of the changed number of the textile machines 5.
[0070] Based on the progress rate calculated by the calculation section
36, the setting section 38 changes (adjusts) the setting of the winding
speed of yarn Y in each textile machme 5. The expression "changes
the setting of the winding speed" can be paraphrased into "resets the
winding speed". It can be also expressed that the setting section 38
"reviews the setting of the winding speed" of yam Y in each textile
machine 5 on the basis of the progress rate calculated by the calculation
section 36. The expression "changes (adjusts) the setting of the
winding speed" does not exclude the case "the setting is not changed".
In other words, the setting section 38 may review the setting of the
winding speed on the basis of the progress rate, and does not have to
change the setting of the winding speed of yam Y in each textile
machine 5 if no problem is found in the progress rate.
[0071] When having received the progress information output from the
calculation section 36, the setting section 38 changes the winding speed
on the basis of the production schedule and the progress rate. When
the progress rate is low against the production schedule, the setting
section 38 changes the setting such that the winding speed becomes
higher. When the progress rate is high compared with the production
schedule, the setting section 38 may change the setting such that the
winding speed becomes lower, or does not have to change the setting of
the winding speed, that is, may maintain the current winding speed.
The setting section 38 changes the setting of the winding speed such
that the winding speed is maintained within the range of the upper limit
or the lower limit. The setting section 38 outputs speed information
indicating the winding speed thus changed to the communication
section 32.
[0072] The setting section 38 changes the target production quantity of
packages P in each textile machine 5 with a higher priority than
changing the winding speed of yam Y in each textile machine 5.
When production of a lot cannot be completed within a production
period (by a production completion date) only by changing the
production quantity of packages P in each textile machine 5, the setting
section 38 changes the winding speed of yam Y in each textile machine
5. After changing the production quantity of packages P in each textile
machine 5, the setting section 38 determines, based on the progress rate
of each textile machine 5, whether the production can be completed
within the production period. If having determined that the production
cannot be completed within the production period, the setting section 38
changes the winding speed of yarn Y in each textile machine 5.
[0073] The following describes a managing method in the yam winding
system 1 with reference to FIG. 5. In FIG. 5, one example of the yam
winding system 1 including the management device 3 and two textile
machines 5 will be described. The two textile machines 5 are to
produce packages P of the same lot.
[0074] As depicted in FIG. 5, to begin with, the management device 3
acquires production plan information (step Sol). Subsequently, the
management device 3 generates setting information based on the
acquired production plan information (step S02). The management
device 3 generates production quantity information specifying the
production quantity of packages P required to be produced in each
textile machine 5. The management device 3 also generates initial
speed information (speed information) indicating an initial value of the
winding speed of yam Y on the basis of the production plan
information. The management device 3 transmits the production
quantity information and the initial speed information thus generated to
each textile machine 5 (step S03).
[0075] When having received the production quantity information and
the initial speed information transmitted from the management device 3,
each textile machine 5 starts production of a package P on the basis of
the production quantity information and the initial speed information
(step S04). Specifically, in the textile machine 5, the machine control
device 7 outputs a command including the initial value of the winding
speed to the unit controller 10 of each winding unit 6. Thus, formation
of a package P in each winding unit 6 is started.
[0076] Subsequently, each textile machine 5 transmits production state
information on the production state of packages P to the management
device 3 (step S05). When having received the production state
information transmitted fi-om each textile machine 5, the management
device 3 acquires the production plan information and the production
state information fi-om the storage section (acquisition step), and
calculates the progress rate of production of packages P in each textile
machine 5 on the basis of the production plan information and the
production state information (step S06, calculation step).
[0077] Subsequently, based on the calculated progress rate, the
management device 3 changes the setting of the production quantity of
packages P in each textile machine 5 (step S07, setting changing step).
Specifically, for example, the management device 3 changes the target
production quantity for each textile machine 5 in accordance with the
progress rate of the textile machine 5. More specifically, when the
progress rate of one textile machine 5 is higher than that of the other
textile machine 5, the management device 3 assigns the target
production quantity assigned to the other textile machine 5 the progress
rate of which is lower to the one textile machine 5 the progress rate of
which is higher.
[0078] The management device 3 transmits production quantity
information indicating the changed target production quantity of
packages P to each textile machine 5 (step S08, transmitting step).
[0079] When having received the production quantity information
transmitted from the management device 3 (receiving step), each textile
machine 5 changes the setting of the target production quantity, and also
controls operation of the textile machine so as to achieve the new target
production quantity (step S09, operation controlling step).
[0080] Subsequently, when having changed the target production
quantity of packages P, each textile machine 5 transmits the production
state information after this change to the management device 3 (step
SlO).
[0081] When having received the production state information
transmitted from each textile machine 5, the management device 3
calculates the progress rate of production of packages P in each textile
machine 5 on the bases of the production plan information and the
production state information (step S 11).
[0082] Subsequently, the management device 3 determines whether
production of a scheduled quantity (target production quantity) of
packages P can be completed within the production period if the current
target production quantities assigned to the respective textile machines 5
are continuously used (step S 12).
[0083] If having determined the production can be completed within the
production period (YES at step S12), the management device 3 ends the
process. If having determined that the production cannot be completed
within the production period (NO at step S 12), the management device
3 changes the setting of the winding speed in each textile machine 5 on
the basis of the calculated progress rate (step S13, setting changing
step).
[0084] The management device 3 transmits speed information
indicating the changed winding speed to each textile machine 5 (step
S 14, transmitting step).
[0085] When having received the speed information transmitted from
the management device 3, each textile machine 5 changes the winding
speed of each winding unit 6 on the basis of the speed information (step
S15, operation controlling step). Specifically, the unit controller 10 in
each winding unit 6 controls the winding device 12 such that the
winding speed based on the speed information is reached.
[0086] In the yam winding system 1, when the production quantity of
produced packages P has reached the production quantity indicated in
the production quantity information, the textile machines 5 end
production of packages P. When the production has been completed,
each textile machine 5 transmits completion information indicating that
the production has been completed to the management device 3 and
5 stops operation. When the production is nearing completion, the
textile machine 5 stops the winding units 6 in the order from fully
wound one to gradually reduce the number of operating winding units 6,
and stops operation when production of packages P in the scheduled
production quantity has been completed. When a package P is still
being formed at the time of production completion, the corresponding
winding unit 6 is preferably operated until this package P is fully
wound.
[0087] In the embodiment above, a mode has been described as one
example in which the production quantity of packages P in each textile
machine 5 is changed once. However, the production quantity of
packages P may be changed more than once. In the embodiment, a
mode has been described as one example in which the winding speed of
yarn Y is changed once. However, the winding speed of yarn Y may
be changed more than once.
[0088] As described in the foregoing, in the yam winding system 1
according to the present embodiment, the management device 3
calculates the progress status based on the production plan information
and the production state information, and changes at least one of the
winding speed of yarn and the production quantity of packages on the
basis of the progress status. By changing at least one of the winding
speed of yam Y and the production quantity of packages P in each
textile machine 5, the production speed of packages P produced in the
textile machine 5 can be adjusted. In the yam winding system 1, the
winding speed of yam Y and the production quantity of packages can be
automatically changed based on the production plan as described above,
and thus the workload of adjusting the production speed can be reduced.
[0089] In the yam winding system 1 according to the present
embodiment, the acquisition section 34 of the management device 3
acquires the production state information including the production
quantity and the production efficiency. With this configuration, the
production state can be accurately determined.
[0090] In the yam winding system 1 according to the present
embodiment, the management device 3 includes the input section 30
configured to receive input of the upper limit and the lower limit of the
winding speed. The setting section 38 of the management device 3
changes the winding speed within a range between the upper limit and
the lower limit input in the input section 30. The upper limit and the
lower limit of the winding speed can be set such that the quality of yam
Y is maintained within a certain range. Thus, by changing the winding
speed within the range between the upper limit and the lower limit of
the winding speed, variation in y m quality during formation of a
package P can be reduced.
[0091] In the yam winding system 1 according to the present
embodiment, the acquisition section 34 of the management device 3
acquires the production plan information including the production
quantity and the production schedule of packages P. With this
configuration, based on the production quantity and the production
schedule of packages P, the calculation section 36 can calculate the
progress rate accurately.
[0092] In the yam winding system 1 according to the present
embodiment, when the progress status is different from each other
between the textile machines 5, the setting section 38 of the
management device 3 assigns the production quantity of packages P
assigned to a textile machine 5 the progress of which is slow to a textile
machine 5 the progress of which is fast. With this configuration, even
when there is a textile machine 5 in which production of packages P is
delayed, this production delay can be compensated for by another textile
machine 5. Consequently, the original production plan can be reliably
accomplished. Furthermore, by assigning the production quantity to
the other textile machine 5, the amount of change in winding speed can
be reduced. Particularly when the number of the textile machines 5 is
larger, the amount of change in winding speed for each textile machine
5 can be further reduced, and influence of the change in winding speed
upon the yarn quality can be further reduced.
[0093] In the yam winding system 1 according to the present
embodiment, the setting section 38 changes the production quantity of
packages P with a higher priority than changing the winding speed of
yam Y. With this configuration, by giving a higher priority to
changing the production quantity, the amount of change in winding
speed can be reduced. Thus, influence of the change in winding speed
upon the yarn quality can be reduced.
[0094] In the yam winding system 1 according to the present
embodiment, when production cannot be completed within the
production period only by changing the production quantity, the setting
section 38 changes the winding speed in each textile machine 5. With
this configuration, the production plan can be reliably accomplished.
[0095] In the yarn winding system 1 according to the present
embodiment, when the progress rate is low against the production
schedule, the setting section 38 sets the winding speed such that the
winding speed becomes higher than its initial value. When the
progress rate is high against the production schedule, the setting section
does not have to change the winding speed. With this configuration,
the production plan can be reliably accomplished, and also variation in
yarn quality during formation of a package P can be reduced.
[0096] Although the present embodiment has been described above in
detail, it is obvious for those skilled in the art that the present
embodiment is not limited to the examples described in this
specification. The present embodiment can be modified and changed
to be implemented without departing fkom the gist and scope of the
present invention defined by the claims. Thus, this specification is
described for the purpose of exemplification, and should not be
construed as being limited to the present embodiment.
[0097] In the embodiment, a mode has been described as one example
in which each textile machine 5 is an automatic winder. However, the
textile machine may be an air spinning machine or an open-end
spinning machine, for example.
[0098] In the embodiment, a mode has been described as one example
in which the yarn winding system 1 includes the management device 3
and a plurality of textile machines 5. However, the yarn winding
system may consist of the management device and one textile machine.
In this case, based on the production plan information and the
production state information of this one textile machine, the
management device calculates the progress status on production of
5 packages in the textile machine. The management device changes the
winding speed of yam in the textile machine on the basis of the progress
status. In this yam winding system, the management device calculates
the progress status based on the production plan information and the
production state information, and changes the winding speed of yam in
the textile machine on the basis of the progress status. In the yarn
winding system, the winding speed of yam can be automatically
changed based on the production plan as described above, and thus the
workload of adjusting the production speed can be reduced.
[0099] In the embodiment, a mode has been described as one example
in which the yam winding system 1 includes the management device 3
and a plurality of textile machines 5. However, the yarn winding
system does not have to include the management device in addition to
the textile machines 5. The yam winding system may consist of the
textile machines. In this yam winding system, one textile machine
among the textile machines serves as a host device having the same
functions as those of the management device 3 in the embodiment. In
other words, the machine control device of any textile machine can
correspond to the management device. The textile machine serving as
a host device and another or other textile machines are connected to
each other so as to be able to communicate therewith via wireless andlor
wired communication. In this configuration, the textile machine
serving as a host device (the machine control device of any textile
machine serving as the management device) may include an input
section (e.g., the above-described input keys 7b) configured to receive
input of a production plan of packages, and may receive input of the
5 production plan in the input section to acquire production plan
information. Alternatively, this textile machine may acquire the
production plan information via a recording medium or a network, for
example.
[0100] The above-described textile machine calculates the progress
status based on the production plan information and the production state
information of the textile machines (including this textile machine).
Based on the progress status, this textile machine changes at least one of
the winding speed of yarn in the textile machines and the production
quantity of packages. In this yam winding system, at least one of the
winding speed of yam in the textile machines and the production
quantity of packages can be automatically changed, and thus the
workload of adjusting the production speed can be reduced.
[0101] In the embodiment, a mode has been described as one example
in which the yam winding system 1 includes the management device 3
and a plurality of textile machines 5, the management device 3 serves as
a host device, and the management device 3 calculates the progress rate,
for example. However, one textile machine among the textile
machines may calculate the progress rate, for example. In this
configuration, this textile machine calculates the progress status on
production of packages on the basis of the production plan information
and the production state information. The textile machine changes the
setting of each textile machine on the basis of the calculated progress
status. The textile machine changes the winding speed of yam on the
basis of the progress status. Alternatively, the textile machine changes
at least one of the winding speed of yam in each textile machine and the
production quantity of packages on the basis of the progress status.
The textile machine may acquire production plan information
transmitted hom the management device, and may acquire production
plan information based on a production plan input in the textile
machine.
[0102] In the embodiment, a mode has been described as one example
in which the yam winding system 1 includes the management device 3
and a plurality of textile machines 5. However, in the present
invention, only one textile machine may be provided. In this
configuration, the textile machine may include an input section
configured to receive input of a production plan of packages P, and may
receive input of a production plan in the input section to acquire
production plan information. Alternatively, this textile machine may
acquire the production plan information via a recording medium or a
network, for example.
[0103] The above-described textile machine includes: an acquisition
section configured to acquire production plan information on a
production plan of packages P and production state information on the
current production state of packages P in the textile machine; a
calculation section configured to calculate the progress status on
production of packages based on the production plan information and
the production state information acquired by the acquisition section; and
a setting section configured to change the setting of the winding speed
of yam based on the progress status calculated by the calculation
section. This textile machine calculates the progress status on the basis
of the production plan information and the production state information
of the textile machine, and changes the winding speed of yam on the
basis of the progress status. By changing the winding speed of yam,
the production speed of packages produced in the textile machine can be
adjusted. In the textile machine, the winding speed of yam can be
automatically changed based on the production plan as described above,
and thus the workload of adjusting the production speed can be reduced.
[0104] The acquisition section of the above-described textile machine
may acquire the progress status of another textile machine. The
above-described textile machine and the other textile machine may be
connected to each other so as to be able to communicate therewith via
wireless andlor wired communication, or may be connected so as to be
able to communicate via another device. In this configuration, the
setting section may change the setting of the winding speed of yam on
the basis of the progress status calculated by the calculation section and
the progress status of the other textile machine acquired by the
acquisition section. In this textile machine, for example, when the
progress status of the other textile machine is behind its scheduled
status, increasing the winding speed of yam can compensate for
production delay in the other textile machine.
[0105] In the embodiment, a mode has been described as one example
in which the management device 3 sets an initial value of the winding
speed of yarn Y on the basis of the production plan information (the
reference value of the winding speed). However, the initial value of
the winding speed of yam Y may be set by the textile machine 5. In
this case, the management device 3 transmits, for example, information
indicating the amount of change in winding speed from the initial value
to the textile machine 5.
[0106] In the embodiment, a mode has been described as one example
in which the input section 30 receives input of a production plan
including the reference value, the upper limit, and the lower limit of the
winding speed of yarn Y. However, the input section may receive
input of a production plan including only the reference value of the
winding speed of yarn Y. In this case, the setting section sets an
allowable range of the winding speed including the reference value, and
also changes the winding speed within the allowable range. The
allowable range can be set such that the quality of yarn is maintained
within a certain range. Thus, by changing the winding speed within
the allowable range, variation in yam quality during formation of a
package can be reduced.
[0107] In the embodiment, a mode has been described as one example
in which the setting section 38 sets the winding speed such that the
winding speed is maintained within the range of the upper limit or the
lower limit. However, the setting section may set the amount of
change in winding speed, and may set the winding speed in accordance
with the amount of change.
[0108] In the embodiment, a mode has been described as one example
in which the calculation section 36 calculates the progress rate as the
progress status. However, the progress status calculated by the
calculation section is not limited to the progress rate.
[0109] In the embodiment, a mode has been described as one example
in which, based on the progress rate calculated by the calculation
section 36, the winding speed of yam Y in each textile machine 5 is
changed, and the speed information is transmitted to the textile machine
5. However, when the progress rate calculated by the calculation
section is inappropriate, the setting section may change the winding
speed. Furthermore, when the progress status is behind a scheduled
status, the setting section may increase the winding speed to a value
larger than an initial value of a set speed that is set based on production
plan information. The scheduled status is set based on the production
plan information. With this configuration, the production plan can be
reliably accomplished.
[O 1 101 In the embodiment, a mode has been described as one example
in which the machine control device 7 includes the display screen 7a
and the input keys 7b as separate components. However, for example,
in the machine control device 7, a touch panel-type display device may
be used, and a display unit and an operation unit may be included in the
same device.
[O 11 11 At least some parts of the embodiment described above may be
optionally used in combination.
[0112] The expression "based on (on the basis of)" used in this
specification does not mean "only based on (only on the basis of)"
unless otherwise specified. In other words, the expression "based on
(on the basis of)" means both "only based on (only on the basis of)" and
"at least based on (at least on the basis of)".
[0113] Procedures, sequences, and the like of each mode/embodiment
described in this specification may be permuted unless contradiction
arises. For example, the method described in this specification
includes various step elements in an exemplary order, which is not
5 limited to the specific order described herein.
