TITLE
CLEARING-LIMIT SETTING DEVICE AND YARN WINDING
MACHINE
TECHNICAL FIELD
[0001] The present disclosure relates to a clearing-limit setting devic5 e
and a yarn winding machine.
BACKGROUND
[0002] For example, a machine control device of an air spinning
machine may have a function of displaying a clearing limit that is a
10 borderline whether a yarn defect needs to be removed in a
two-dimensional field having coordinate axes respectively representing
the length and the thickness of a yarn defect (see Japanese Unexamined
Patent Publication No. 2007-211363, for example).
SUMMARY
15 [0003] When part of a clearing limit displayed as described above is
changed, the length and the thickness of the yarn defect that determine
this part are input as numerical values. However, there is a situation in
which the changed part of the clearing limit does not have an expected
shape and accordingly the numerical values need to be input again and
20 again.
[0004] In view of this, the present disclosure aims to provide a
clearing-limit setting device and a yarn winding machine that can easily
and appropriately change at least one portion of a clearing limit.
[0005] A clearing-limit setting device according to one aspect of the
25 present disclosure includes: a display unit that displays, in a
two-dimensional field having coordinate axes respectively representing
3
length and thickness of a yarn defect, a clearing limit that is a borderline
whether the yarn defect needs to be removed; a first input section that
receives selection of at least one portion of the clearing limit; a second
input section that indicates a plurality of moving directions for the
clearing limit and receives selection of a moving direction thereamong5 ;
and a processor that changes the clearing limit such that the at least one
portion selected with the first input section moves in the moving
direction selected with the second input section by a predetermined
amount, and causes the display unit to display the clearing limit
10 changed.

DETAILED DESCRIPTION
15 [0020] 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.
[0021] As depicted in FIG. 1, a yarn winding machine 1 includes a
20 plurality of yarn winding units 2, a plurality of unit control devices 3,
and a machine control device (clearing-limit setting device) 4. The
yarn winding machine 1 is an automatic winder, an air spinning
machine, an open-end spinning machine, or a ring spinning machine, for
example. Each yarn winding unit 2 winds yarn and forms a package.
25 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
5
under management thereof. The machine control device 4
communicates with each unit control device 3 and controls operation of
the yarn winding machine 1. Each unit control device 3 may be
provided for every yarn winding unit 2.
[0022] As depicted in FIG. 2, each yarn winding unit 2 includes a yar5 n
supplying section 21, a yarn monitoring section 22, a yarn joining
section 23, and a winding section 24. When the yarn winding machine
1 is an automatic winder, each yarn winding unit 2 may include a
tension applying device that applies tension and a tension sensor that
10 measures the tension of yarn. When the yarn winding machine 1 is an
air spinning machine, each yarn winding unit 2 may include a tension
sensor that measures the tension of yarn, a yarn storage device that
stores therein the yarn, and a waxing device that applies wax to the
yarn.
15 [0023] The yarn supplying section 21 supplies yarn. When the yarn
winding machine 1 is the automatic winder, the yarn supplying section
21 includes a bobbin supporting device that supports a bobbin. When
the yarn winding machine 1 is the air spinning machine, the yarn
supplying section 21 includes a drafting device that drafts a fiber band
20 and an air spinning device that generates yarn by twisting the drafted
fiber band using swirling airflow.
[0024] The yarn monitoring section 22 monitors the yarn between the
yarn supplying section 21 and the winding section 24, and detects a yarn
defect. The yarn monitoring section 22 includes a detection device 22a
25 and a control device 22b. The detection device 22a is an optical sensor
that emits light to yarn and detects time variation of thickness
6
(diameter) of the yarn on the basis of the amount of received light, or a
capacitive sensor that causes yarn to pass through an electric field and
detects time variation of thickness (mass) of the yarn on the basis of
variation of capacitance. The detection device 22a outputs waveform
data indicating time variation of yarn thickness to the control devic5 e
22b. Based on the waveform data, the control device 22b calculates
yarn defect data indicating the length and the thickness of the yarn
defect, and outputs the yarn defect data to the unit control device 3. If
the unit control device 3 has determined based on the yarn defect data
10 that the yarn defect needs to be removed, the yarn is cut by, for example,
a cutter provided to the yarn winding unit 2. When the yarn winding
machine 1 is the air spinning machine, the yarn may be cut by
interrupting generation of the yarn by the air spinning device. The
yarn monitoring section 22 can also detect a foreign matter contained in
15 the yarn and yarn breakage, for example. Based on the yarn defect
data, the control device 22b may determine whether the yarn defect
needs to be removed, and a cutter provided to the yarn monitoring
section 22 may cut the yarn.
[0025] When the yarn has been cut in order to remove a yarn defect
20 detected by the yarn monitoring section 22 or yarn breakage has been
detected by the yarn monitoring section 22, the yarn joining section 23
performs splicing operation of splicing the yarn on the yarn supplying
section 21 side and the yarn on the winding section 24 side. The yarn
joining section 23 includes a first yarn catching-and-guiding device, a
25 second yarn catching-and-guiding device, and a splicing part. The first
yarn catching-and-guiding device catches the yarn on the yarn
7
supplying section 21 side by suction, and guides the yarn to the splicing
part. The second yarn catching-and-guiding device catches the yarn on
the winding section 24 side by suction, and guides the yarn to the
splicing part. The splicing part is, for example, a splicer using
compressed air, a piecer using a seed yarn, or a knotter configured t5 o
mechanically splice yarns, and splices the yarns thus guided. When
the yarn winding machine 1 is a spinning machine, for example, the
yarn joining section 23 may be configured as a splicing carrier that can
travel with respect to the yarn winding units 2.
10 [0026] The winding section 24 winds the yarn around a bobbin and
forms a package. The winding section 24 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 and rotates the
15 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.
[0027] As depicted in FIG. 3, the machine control device 4 includes a
20 touch panel (display unit) 41, a processor 42, and a storage 43. The
touch panel 41 displays various types of information for the operator,
and receives various types of information input from the operator. The
processor 42 acquires the yarn defect data output from the yarn
monitoring section 22 of each yarn winding unit 2. The processor 42
25 causes the storage 43 to store therein, for each yarn winding unit 2, the
acquired yarn defect data in a manner associated with information on
8
whether the yarn defect has been removed or has not been removed.
The processor 42 and the storage 43 physically include a central
processing unit (CPU), a read only memory (ROM), and a random
access memory (RAM). The processor 42 is a circuit configured to
perform respective operations described later5 .
[0028] The processor 42 generates a two-dimensional field, and causes
the touch panel 41 to display the two-dimensional field together with a
clearing limit. FIG. 4 is a diagram illustrating one example of a screen
of the touch panel 41. As depicted in FIG. 4, the two-dimensional field
10 51 is a coordinate system having coordinate axes respectively
representing the length and the thickness of the yarn defect. Herein,
the abscissa represents the length of the yarn defect, and the ordinate
represents the thickness (ratio to a specified yarn thickness) of the yarn
defect. The clearing limit 52 is a borderline whether the yarn defect
15 needs to be removed, and includes a plurality of portions 52a. Herein,
the clearing limit 52 is set for respective channels indicating types of
yarn defects such as neps N1 and N2, slubs S1 and S2, a long yarn L,
thin yarns T1 and T2. In other words, the respective portions 52a
correspond to the neps N1 and N2, the slubs S1 and S2, the long yarn L,
20 and the thin yarns T1 and T2, for example.
[0029] The processor 42 causes the touch panel 41 to display a current
set-value column 53 and a simulation set-value column 54. In the
current set-value column 53, current values of lengths and thicknesses
of yarn defects that determine the clearing limit 52 are listed for the
25 respective channels. In the simulation set-value column 54, simulated
values of lengths and thicknesses of yarn defects that determine the
9
clearing limit 52 are listed for the respective channels. The respective
portions 52a constituting the current clearing limit 52 are set so as to
intersect the current values of lengths and thicknesses of the
corresponding yarn defects. When at least one portion 52a in the
current clearing limit 52 is changed (details will be described later5 ),
simulated values of the length and the thickness of the yarn defect are
changed so as to correspond to the changed portion 52a. In the current
set-value column 53 and the simulation set-value column 54, portions
indicating the respective channels are configured as buttons 55.
10 [0030] The processor 42 causes each unit control device 3 to control
operation of the corresponding yarn winding units 2 such that yarn
defects having values within an area on the specified yarn thickness side
(the side of the abscissa in which the thickness of the yarn defect is 0%)
with respect to the clearing limit 52 need not to be removed, and yarn
15 defects having values within an area on the side opposite to the
specified yarn thickness side (the side of the abscissa in which the
thickness of the yarn defect is 0%) with respect to the clearing limit 52
need to be removed. Based on the yarn defect data stored in the
storage 43, the processor 42 determines the positions of yarn defects in
20 the two-dimensional field 51, and causes the touch panel 41 to display
the yarn defects as dots. Herein, the processor 42 causes yarn defects
that have not been removed in the yarn to be displayed as hollow
circular dots in the two-dimensional field 51, and causes yarn defects
that have been removed from the yarn to be displayed as black square
25 dots in the two-dimensional field 51.
[0031] In the machine control device 4, at least one portion 52a in the
10
current clearing limit 52 can be changed. The following describes
change of the clearing limit 52 with reference to one example thereof.
[0032] For example, as depicted in FIG. 5, when the operator has
touched (has pressed, has come into physical contact with, etc.) a
portion 52a corresponding to the slub S2 in the current clearing limit 525 ,
the display mode (e.g., at least one of line type, thickness, and color) of
the touched portion 52a is changed, the display mode (e.g., at least one
of font and color) of a button 55 corresponding to the slub S2 among the
buttons 55 in the set-value column 53 is changed, and an operation
10 section 60 is displayed. At this time, the operator can select a portion
52a corresponding to a channel other than the slub S2 in the current
clearing limit 52, and also can select a certain number of portions 52a
therein at the same time.
[0033] In this manner, the clearing limit 52 functions as a first input
15 section that receives selection of at least one portion 52a that has been
touched. The processor 42 causes the touch panel 41 to display the
portion 52a selected with the clearing limit 52 so that the portion 52a
can be identified, and also causes the touch panel 41 to display a button
55 corresponding to the portion 52a so that the button 55 can be
20 identified. Furthermore, when the clearing limit 52 has received
selection of at least one portion 52a, the processor 42 causes the touch
panel 41 to display the operation section 60 such that the operation
section does not overlap this portion 52a.
[0034] Similarly also when the operator has touched the button 55
25 corresponding to the slub S2 among the buttons 55 in the set-value
column 53, the display mode of the touched button 55 is changed, the
11
display mode of a portion corresponding to the slub S2 in the current
clearing limit 52 is changed, and the operation section 60 is displayed.
At this time, the operator can select a button 55 corresponding to a
channel other than the slub S2 among the buttons 55 in the set-value
column 53, and also can select a certain number of buttons 55 therein a5 t
the same time.
[0035] In this manner, the buttons 55 (the buttons 55 displayed
separately from the clearing limit 52 by the touch panel 41) each
corresponding to the portions 52a constituting the clearing limit 52
10 function as the first input section that receives selection of a portion 52a
corresponding to at least one button 55 that has been touched. The
processor 42 causes the touch panel 41 to display the portion 52a
selected with the button 55 so that the portion 52a can be identified, and
also causes the touch panel 41 to display the button 55 corresponding to
15 the portion 52a so that the button 55 can be identified. Furthermore,
when the button 55 has received selection of at least one portion 52a,
the processor 42 causes the touch panel 41 to display the operation
section 60 such that the operation section does not overlap this portion
52a.
20 [0036] The operation section 60 functions as a second input section that
indicates a plurality of moving directions for the clearing limit 52 and
receives selection of a moving direction thereamong. The processor
42 changes the clearing limit 52 such that a portion 52a selected with
the clearing limit 52 or a button 55 moves in a moving direction
25 selected with the operation section 60 by a predetermined amount, and
causes the touch panel 41 to display the clearing limit 52 thus changed.
12
Specifically, the operation section 60 has moving-direction instruction
buttons 61, a moving-amount change button 62, a display cancel button
63, and a display-position move button 64. The moving-direction
instruction buttons 61 indicate a plurality of moving directions at
intervals of a predetermined angle and receive selection of a movin5 g
direction thereamong. Herein, the moving-direction instruction
buttons 61 are arranged around the moving-amount change button 62 at
intervals of 45 degrees, and indicate moving directions of upper,
upper-right, right, lower-right, lower, lower-left, left, and upper-left
10 clockwise in this order.
[0037] For example, as depicted in FIG. 6, when the operator has
touched a moving-direction instruction button 61 indicating the right
moving direction, a portion 52a corresponding to the selected slub S2
moves rightward by the predetermined amount. At this time, the
15 processor 42 causes the touch panel 41 to display the clearing limit 52
changed and also the clearing limit 52 before being changed so that
these clearing limits can be identified from one another by changing
display modes. The processor 42 changes the simulated values of
length and thickness of the yarn defect that determine the portion 52a
20 corresponding to the slub S2 in the clearing limit 52 changed, and
causes the touch panel 41 to display the resulting simulated values. In
the example depicted in FIG. 6, the portion 52a corresponding to the
slub S2 moves rightward by the predetermined amount, and thus the
value and the color, for example, of only the simulated value of length
25 of the yarn defect are changed.
[0038] As depicted in FIG. 7, when the operator has touched a
13
moving-direction instruction button 61 indicating the upper moving
direction, the portion 52a corresponding to the selected slub S2 moves
upward by the predetermined amount. At this time, the processor 42
causes the touch panel 41 to display the clearing limit 52 changed and
also the clearing limit 52 before being changed so that these clearin5 g
limits can be identified from one another by changing display modes.
The processor 42 changes the simulated values of length and thickness
of the yarn defect that determine the portion 52a corresponding to the
slub S2 in the clearing limit 52 changed, and causes the touch panel 41
10 to display the resulting simulated values. In the example depicted in
FIG. 7, the portion 52a corresponding to the slub S2 moves upward by
the predetermined amount, and thus the value and the color, for
example, of only the simulated value of thickness of the yarn defect are
changed.
15 [0039] As depicted in FIG. 8, when the operator has touched a
moving-direction instruction button 61 indicating the upper-right
moving direction, the portion 52a corresponding to the selected slub S2
moves upper-rightward by the predetermined amount. At this time, the
processor 42 causes the touch panel 41 to display the clearing limit 52
20 changed and also the clearing limit 52 before being changed so that
these clearing limits can be identified from one another by changing
display modes. The processor 42 changes the simulated values of
length and thickness of the yarn defect that determine the portion 52a
corresponding to the slub S2 in the clearing limit 52 changed, and
25 causes the touch panel 41 to display the resulting simulated values. In
the example depicted in FIG. 8, the portion 52a corresponding to the
14
slub S2 moves upper-rightward by the predetermined amount, and thus
the values and the colors, for example, of the simulated values of length
and thickness of the yarn defect are changed.
[0040] The moving-amount change button 62 receives change of the
amount (predetermined amount) by which the selected portion 525 a
moves in response to touching once the moving-direction instruction
button 61. For example, each time the moving-amount change button
62 is touched, the processor 42 changes the moving amount to 1
(moving amount that is one time as long as a reference value), to 10
10 (moving amount that is 10 times as long as the reference value), and to
100 (moving amount that is 100 times as long as the reference value).
The reference value for the moving amount can be set for each channel.
[0041] The display cancel button 63 receives cancellation of display of
the operation section 60 on the touch panel 41. Specifically, when the
15 clearing limit 52 or a button 55 has received selection of at least one
portion 52a, the processor 42 causes the touch panel 41 to display the
operation section 60, and when the display cancel button 63 has been
touched, the processor cancels the display of the operation section 60 to
release the selection of the portion 52a.
20 [0042] The display-position move button 64 receives movement of the
display position of the operation section 60 on the touch panel 41. The
operator can move the operation section 60 to any position in the screen
by touching the display-position move button 64. In default settings,
as depicted in FIG. 9, the operation section 60 is displayed in an
25 upper-right area of the two-dimensional field 51 in a manner in which
part thereof lies out of the area.
15
[0043] When portions 52a corresponding to the neps N1 and N2 and the
slubs S1 and S2 in the clearing limit 52 are displayed in an enlarged
manner, the operation section 60 is displayed in an upper-right area of
the two-dimensional field 51 in a manner in which part thereof lies out
of the area as depicted in FIG. 10. If portions 52a corresponding to th5 e
long yarn L and the thin yarn T2 in the clearing limit 52 are displayed in
an enlarged manner, when the portion 52a corresponding to the long
yarn L has been selected, the operation section 60 is displayed in an
lower-right area of the two-dimensional field 51 in a manner in which
10 part thereof lies out of the area as depicted in FIG. 11. If the portions
52a corresponding to the long yarn L and the thin yarn T2 in the
clearing limit 52 are displayed in an enlarged manner, when the portion
52a corresponding to the thin yarn T2 has been selected, the operation
section 60 is displayed in an upper-right area of the two-dimensional
15 field 51 in a manner in which part thereof lies out of the area as depicted
in FIG. 12.
[0044] In the machine control device 4, when at least one portion 52a in
the current clearing limit 52 has been changed, a clearing simulation can
be performed. The following describes the clearing simulation with
20 reference to FIG. 13.
[0045] Based on the yarn defect data stored in the storage 43 and the
clearing limit 52 before being changed (i.e., the current clearing limit)
(portions indicated by the continuous line and the dashed line in FIG.
13), the processor 42 calculates a first yarn processing result, and causes
25 the touch panel 41 to display the first yarn processing result. The
processor 42 causes the first yarn processing result to be displayed as a
16
yarn processing result based on the clearing limit 52 before being
changed in a current result column 56. Based on the yarn defect data
stored in the storage 43 and the clearing limit 52 changed (portions
indicated by the continuous line and the dashed and single-dotted line in
FIG. 13), the processor 42 calculates a second yarn processing result5 ,
and causes the touch panel 41 to display the second yarn processing
result. The processor 42 causes the second yarn processing result to be
displayed as a yarn processing result based on the clearing limit 52
changed in a simulation result column 57.
10 [0046] In the current result column 56, as the first yarn processing
result, the number (n) of removed yarn defects and the converted
number (/100 km) of removed yarn defects per unit length (herein, 100
kilometers) are displayed for the respective channels. The number (n)
of removed yarn defects in the current result column 56 is the measured
15 number of yarn defects that have been removed, and corresponds to the
number of dots of yarn defects having values within an area on the side
opposite to the specified yarn thickness side (the side of the abscissa in
which the thickness of the yarn defect is 0%) with respect to the
clearing limit 52 before being changed. The number (n) of removed
20 yarn defects may be converted into a number per unit time (e.g., 1
hour), and this converted number of removed yarn defects may be
displayed in the current result column 56. In the current result column
56, as the first yarn processing result, either one of the number of
removed yarn defects and the converted number of removed yarn
25 defects per unit length may be displayed.
[0047] Similarly, in the simulation result column 57, as the second yarn
17
processing result, the number (n) of removed yarn defects and the
converted number (/100 km) of removed yarn defects per unit length
(herein, 100 kilometers) are displayed for the respective channels. The
number (n) of removed yarn defects in the simulation result column 57
is a predicted number based on the measured number of yarn defects5 ,
and corresponds to the number of dots of yarn defects having values
within an area on the side opposite to the specified yarn thickness side
(the side of the abscissa in which the thickness of the yarn defect is 0%)
with respect to the clearing limit 52 changed. The number (n) of
10 removed yarn defects may be converted into a number per unit time
(e.g., 1 hour), and this converted number of removed yarn defects may
be displayed in the simulation result column 57. In the simulation
result column 57, as the second yarn processing result, either one of the
number of removed yarn defects and the converted number of removed
15 yarn defects per unit length may be displayed. In the simulation result
column 57, the amount of increase or decrease of the second yarn
processing result from the first yarn processing result may be displayed.
[0048] In the example depicted in FIG. 13, portions 52a corresponding
to the nep N2 and the slub S1 in the clearing limit 52 have been selected
20 with the clearing limit 52 or buttons 55, and these portions 52a have
been moved downward by the predetermined amount with the operation
section 60 (see the current set-value column 53 and the simulation
set-value column 54). As a simulation result when the clearing limit
52 has been changed in this manner, the numbers of removed yarn
25 defects for the nep N and the slub S have increased (see the current
result column 56 and the simulation result column 57). This clearing
18
simulation is started when the operator touches a simulation button 58,
and is ended when the operator touches again the simulation button 58.
A reset button 59 is a button configured to receive cancellation (reset) of
setting (during simulation) of changing the clearing limit 52. The
simulation button 58 and the reset button 59 do not have to be provided5 .
In this case, when the clearing limit 52 has been changed, the second
yarn processing result may be automatically (without waiting for
another instruction by the operator) displayed. When the operator has
touched a newly provided enter button (not depicted), the clearing limit
10 52 changed through simulation may be set as a new clearing limit 52.
[0049] In a row titled "CLASS" in the current result column 56 and the
simulation result column 57, the number of removed yarn defects when
what is called "class cut" is performed is displayed. The class cut is to
remove yarn defects having values within an area that is selected from
15 among a plurality of areas (classes) constituting the two-dimensional
field 51. In a row titled "Sum" in the current result column 56 and the
simulation result column 57, the sum of the numbers (n) of removed
yarn defects and the sum of the numbers (/100 km) of removed yarn
defects per unit length are displayed. The clearing limit 52 may be
20 configured to be changed in response to input of the number of removed
yarn defects per unit length (e.g., 100 kilometers). In this case, the
clearing limit 52 may be configured to be finely adjusted by operating
the operation section 60 after a temporary clearing limit 52 depending
on the number of removed yarn defects per unit length is displayed.
25 [0050] The processor 42 sets the clearing limit 52 before being changed
or the clearing limit 52 changed as a new clearing limit 52. This
19
setting of the clearing limit 52 is performed when the operator who has
viewed the clearing simulation result touches a button (not depicted) for
selecting the clearing limit 52 before being changed or the clearing limit
52 changed.
[0051] Changing of the clearing limit 52 and displaying of the clearin5 g
limit 52 changed are functions of a first mode that the processor 42 has.
The processor 42 has a second mode in addition to the first mode. The
second mode is a mode of changing the clearing limit 52 so as to
remove yarn defects corresponding to an area touched among the areas
10 constituting the two-dimensional field 51, and causing the touch panel
41 to display the clearing limit 52 changed. For example, as depicted
in FIG. 14, when the class D1 has been touched in the second mode, the
processor 42 changes the part D1a of the clearing limit 52 so as to
remove yarn defects having values within the class D1.
15 [0052] Alternatively, the second mode may be a mode of changing the
clearing limit 52 so as not to remove yarn defects corresponding to an
area touched among the areas constituting the two-dimensional field 51,
and causing the touch panel 41 to display the clearing limit 52 changed.
In this case, for example, as depicted in FIG. 14, when the class D0 has
20 been touched in the second mode, the processor 42 changes the part D0a
of the clearing limit 52 so as not to remove yarn defects having values
within the class D0.
[0053] As described in the foregoing, with the machine control device
4, at least one portion 52a among the portions 52a constituting the
25 clearing limit 52 can be selected, and the selected portion 52a can be
moved. The operation section 60 that moves the selected portion 52a
20
indicates the moving directions for the clearing limit 52. This allows
the operator to intuitively move the selected portion 52a in a desired
moving direction with the operation section 60. Thus, with the
machine control device 4, at least one portion 52a among the portions
52a constituting the clearing limit 52 can be easily and appropriatel5 y
changed. In other words, with the machine control device 4, at least
one portion of the clearing limit 52 can be easily and appropriately
changed.
[0054] In the machine control device 4, the clearing limit 52 displayed
10 by the touch panel 41 receives selection of a portion 52a that has been
touched among the portions 52a. This allows the operator to easily
select a desired portion 52a in the clearing limit 52.
[0055] In the machine control device 4, the processor 42 causes the
touch panel 41 to display the selected portion 52a such that the portion
15 52a becomes identifiable. This allows the operator to grasp whether
the desired portion 52a in the clearing limit 52 has been selected
correctly.
[0056] In the machine control device 4, the clearing limit 52 includes
the portions 52a, and receives selection of at least one portion 52a.
20 This allows the operator to easily select a desired portion from among
the portions 52a that are divided in advance.
[0057] In the machine control device 4, each of the portions 52a is set
depending on the type of the yarn defect. This allows one portion of
the clearing limit 52 to be easily selected and changed depending on the
25 type of the yarn defect.
[0058] In the machine control device 4, the buttons 55 that are
21
displayed separately from the clearing limit 52 by the touch panel 41
receive selection of a portion 52a corresponding to a button 55 that has
been touched among the buttons 55. This allows the operator to easily
select a desired portion 52a of the clearing limit 52 even among portions
52a of the clearing limit 52 that are finely displayed5 .
[0059] In the machine control device 4, the processor 42 causes the
touch panel 41 to display the selected button 55 such that the button 55
becomes identifiable. This allows the operator to grasp whether the
desired portion 52a in the clearing limit 52 has been selected correctly.
10 [0060] In the machine control device 4, the touch panel 41 displays the
operation section 60. This enables the operation section 60 to be
provided to the operator at appropriate timing, thereby eliminating the
need to provide an additional operation section 60.
[0061] In the machine control device 4, the processor 42 causes the
15 touch panel 41 to display the operation section 60 when selection of a
portion 52a has been received. This can prevent the operation section
60 from occupying a display area of the touch panel 41 during a period
of time other than when the clearing limit 52 is changed.
[0062] In the machine control device 4, the processor 42 causes the
20 touch panel 41 to display the operation section 60 such that the
operation section does not overlap the selected portion 52a. This
allows the operator to operate the operation section 60 while visually
checking the selected portion 52a.
[0063] In the machine control device 4, the operation section 60
25 includes the moving-direction instruction buttons 61 that indicates a
plurality of moving directions at intervals of a predetermined angle and
22
receives selection of a moving direction thereamong. This allows the
operator to intuitively grasp the moving directions and operate the
operation section 60.
[0064] In the machine control device 4, the operation section 60
includes the moving-amount change button 62 that receives change of 5 a
predetermined amount. This allows the operator to move the selected
portion 52a by a large amount or to move the selected portion by a small
amount.
[0065] In the machine control device 4, the operation section 60
10 includes the display cancel button 63 that receives cancellation of
display of the operation section 60 on the touch panel 41. This allows
the operator to easily change the state in which the clearing limit 52 has
been selected back to the state in which the clearing limit has not been
selected.
15 [0066] In the machine control device 4, the operation section 60
includes the display-position move button 64 that receives movement of
the display position of the operation section 60 on the touch panel 41.
This allows the operator to move the operation section 60 to any
position in the display area of the touch panel 41 to check an area
20 hidden by the operation section 60 in the display area.
[0067] In the machine control device 4, the processor 42 has: the first
mode of changing the clearing limit 52 as described above and causing
the touch panel 41 to display the clearing limit 52 changed; and the
second mode of changing the clearing limit 52 so as to remove or not to
25 remove the yarn defect corresponding to an area touched among a
plurality of areas constituting the two-dimensional field 51 and causing
23
the touch panel 41 to display the clearing limit 52 changed. This
allows the operator to change the clearing limit 52 with the operation
section 60, and also allows the operator to change the clearing limit 52
on the basis of area designation in the two-dimensional field 51.
[0068] In the machine control device 4, the processor 42 may cause th5 e
touch panel 41 to display the clearing limit 52 changed and also the
clearing limit 52 before being changed. This allows the operator to
compare the clearing limit 52 changed with the clearing limit 52 before
being changed.
10 [0069] In the machine control device 4, the processor 42 acquires yarn
defect data indicating the length and the thickness of the yarn defect,
calculates a first yarn processing result based on the yarn defect data
and the clearing limit 52 before being changed, calculates a second yarn
processing result based on the yarn defect data and the clearing limit 52
15 changed, and causes the touch panel 41 to display the first yarn
processing result and the second yarn processing result. This allows
the operator to compare the first yarn processing result with the second
yarn processing result to evaluate each of the clearing limit 52 before
being changed and the clearing limit 52 changed.
20 [0070] In the machine control device 4, the processor 42 sets the
clearing limit 52 before being changed or the clearing limit 52 changed
as a new clearing limit 52. This allows the operator to set the clearing
limit 52 before being changed or the clearing limit 52 changed as a new
clearing limit 52.
25 [0071] The yarn winding machine 1 includes: the yarn supplying
section 21 that supplies yarn; the winding section 24 that winds the yarn
24
and forms a package; the yarn monitoring section 22 that monitors the
yarn between the yarn supplying section 21 and the winding section 24,
and detects a yarn defect; the yarn joining section 23 that, when the yarn
has been cut to remove the yarn defect detected by the yarn monitoring
section 22, performs splicing operation of splicing the yarn on the yar5 n
supplying section 21 side and the yarn on the winding section 24 side;
and the machine control device 4. The yarn winding machine 1
includes the machine control device 4 described above, and thus can
remove a yarn defect appropriately.
10 [0072] Although one embodiment of the present disclosure has been
described above, the clearing-limit setting device and the yarn winding
machine of the present disclosure are not limited to the embodiment.
[0073] In the embodiment, the clearing limit 52 and the buttons 55
displayed by the touch panel 41 function as the first input section that
15 receives selection of at least one portion 52a among the portions 52a
constituting the clearing limit 52. However, separately from the touch
panel 41, a first input section including a mechanical button may be
provided.
[0074] In the embodiment, the operation section 60 displayed by the
20 touch panel 41 functions as the second input section that indicates a
plurality of moving directions for the clearing limit 52 and receives
selection of a moving direction thereamong. However, separately from
the touch panel 41, a second input section including a mechanical button
and a lever may be provided.
25 [0075] In the embodiment, the portions 52a constituting the clearing
limit 52 correspond to the respective channels. However, the portions
25
52a may correspond to units other than the channels.
[0076] In the embodiment, the machine control device 4 of the yarn
winding machine 1 functions as the clearing-limit setting device.
However, for example, a management device located separately from
the yarn winding machine 1 may function as the clearing-limit settin5 g
device. At a machine end portion of the yarn winding machine 1,
beside the machine control device 4, a clearing setting device dedicated
to the yarn monitoring section 22 may be provided.
[0077] The processor 42 may also acquire waveform data output from
10 the detection device 22a of the yarn monitoring section 22, in addition
to acquiring yarn defect data from the control device 22b of the yarn
monitoring section 22. Alternatively, the processor 42 may acquire
only waveform data output from the detection device 22a of the yarn
monitoring section 22, without acquiring yarn defect data from the
15 control device 22b of the yarn monitoring section 22. In this case, the
processor 42 can calculate yarn defect data based on the acquired
waveform data.
[0078] In the current result column 56 and the simulation result column
57, the amount of production may be displayed together with the
20 number of removed yarn defects. When the target number of removed
yarn defects or the target amount of production has been input, the
clearing limit 52 corresponding to this number or amount may be
displayed, and then the clearing limit 52 may be able to be finely
adjusted by operating the operation section 60. As a selecting method
25 for selecting a portion 52a that may be changed in the clearing limit 52,
the clearing limit 52 may be touched, or the corresponding button 55
26
may be touched. All portions of the clearing limit 52 may be selected.
[0079] The processor 42 may have: the first mode of changing the
clearing limit 52 as described above and causing the touch panel 41 to
display the clearing limit 52 changed; and a second mode of causing the
touch panel 41 to display an area touched among a plurality of 5 f areas
constituting the two-dimensional field 51 such that whether to remove
or not to remove a yarn defect corresponding to the touched area
becomes distinguishable. This allows the operator to change the
clearing limit 52 with the operation section 60, and also allows the
10 operator to change a clearing area on the basis of area designation in the
two-dimensional field 51.
[0080] If the clearing-limit setting device has the above-described
function of setting the clearing limit, the clearing-limit setting device
does not have to have the above-described function of performing the
15 clearing simulation. Alternatively, the clearing-limit setting device
may have the above-described function of performing the clearing
simulation as an additional function. In this case also, at least one
portion 52a among the portions 52a constituting the clearing limit 52
can be easily and appropriately changed, and thus the clearing-limit
20 setting device and the yarn winding machine of the present disclosure
are significantly effective.
[0081] In the embodiment, the clearing limit 52 is divided (segmented)
into the portions 52a in advance, and at least one portion 52a among the
portions 52a is selectable by the operator. However, at least one
25 portion of clearing limit 52 may be selectable by the operator without
dividing the clearing limit 52 in advance. For example, at least one
27
portion of the clearing limit 52 may be selectable when the operator
inputs with an input section a numerical range (e.g., at least one of the
upper limit and the lower limit of at least one of thickness and length) of
the clearing limit 52. Alternatively, at least one portion of the clearing
limit 52 may be selectable when the operator touches part of th5 e
clearing limit 52 in a tracing manner on the touch panel 41.
[0082] The at least one portion of the clearing limit 52 selection of
which the first input section receives may be one continuous portion, or
may be two or more portions located separately from each other.
10 When the clearing limit 52 is divided into the portions 52a in advance,
the at least one portion may be one portion, may be two or more
portions continuously located, or may be two or more portions located
separately from each other.
[0083] At least some parts of the embodiment and modifications
15 described above may be optionally used in combination.
[0084] A clearing-limit setting device according to one aspect of the
present disclosure includes: a display unit that displays, in a
two-dimensional field having coordinate axes respectively representing
length and thickness of a yarn defect, a clearing limit that is a borderline
20 whether the yarn defect needs to be removed; a first input section that
receives selection of at least one portion of the clearing limit; a second
input section that indicates a plurality of moving directions for the
clearing limit and receives selection of a moving direction thereamong;
and a processor that changes the clearing limit such that the at least one
25 portion selected with the first input section moves in the moving
direction selected with the second input section by a predetermined
28
amount, and causes the display unit to display the clearing limit
changed.
[0085] With this clearing-limit setting device, at least one portion of the
clearing limit can be selected, and the at least one portion selected can
be moved. The second input section that moves the at least on5 e
portion selected indicates the moving directions for the clearing limit.
This allows an operator to intuitively move the at least one portion
selected in a desired moving direction with the second input section.
Thus, with this clearing-limit setting device, at least one portion of the
10 clearing limit can be easily and appropriately changed.
[0086] In the clearing-limit setting device according to one aspect of the
present disclosure, the first input section may include the clearing limit
displayed by the display unit and receive selection of at least one
portion that has been touched in the clearing limit. This allows the
15 operator to easily select a desired portion in the clearing limit.
[0087] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may cause the display unit to display
the at least one portion selected with the first input section such that the
at least one portion becomes identifiable. This allows the operator to
20 grasp whether the desired portion in the clearing limit has been selected
correctly.
[0088] In the clearing-limit setting device according to one aspect of the
present disclosure, the clearing limit may include a plurality of portions,
and the first input section may receive selection of at least one portion
25 among the portions. This allows the operator to easily select a desired
portion from among a plurality of portions that are divided in advance.
29
[0089] In the clearing-limit setting device according to one aspect of the
present disclosure, each of the portions may be set depending on the
type of the yarn defect. This allows one portion of the clearing limit to
be easily selected and changed depending on the type of the yarn defect.
[0090] In the clearing-limit setting device according to one aspect of th5 e
present disclosure, the display unit may display a plurality of buttons
respectively corresponding to the portions separately from the clearing
limit, and the first input section may include the buttons displayed by
the display unit and receive selection of a portion corresponding to a
10 button that has been touched among the buttons. This allows the
operator to easily select a desired portion of the clearing limit even
among portions of the clearing limit that are finely displayed.
[0091] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may cause the display unit to display
15 the button selected with the first input section such that the button
becomes identifiable. This allows the operator to grasp whether the
desired portion in the clearing limit has been selected correctly.
[0092] In the clearing-limit setting device according to one aspect of the
present disclosure, the second input section may be an operation section
20 displayed by the display unit. This enables the operation section to be
provided to the operator at appropriate timing, thereby eliminating the
need to provide an additional operation section.
[0093] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may cause the display unit to display
25 the operation section when the first input section has received selection
of the at least one portion. This can prevent the operation section from
30
occupying a display area of the display unit during a period of time
other than when the clearing limit is changed.
[0094] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may cause the display unit to display
the operation section such that the operation section does not overla5 p
the at least one portion selected with the first input section. This
allows the operator to operate the operation section while visually
checking the selected portion.
[0095] In the clearing-limit setting device according to one aspect of the
10 present disclosure, the operation section may include a
moving-direction instruction button that indicates a plurality of moving
directions at intervals of a predetermined angle and receives selection of
a moving direction thereamong. This allows the operator to intuitively
grasp the moving directions and operate the operation section.
15 [0096] In the clearing-limit setting device according to one aspect of the
present disclosure, the operation section may further include a
moving-amount change button that receives change of a predetermined
amount. This allows the operator to move the selected portion by a
large amount or to move the selected portion by a small amount.
20 [0097] In the clearing-limit setting device according to one aspect of the
present disclosure, the operation section may further include a display
cancel button that receives cancellation of display of the operation
section on the display unit. This allows the operator to easily change
the state in which the clearing limit has been selected back to the state in
25 which the clearing limit has not been selected.
[0098] In the clearing-limit setting device according to one aspect of the
31
present disclosure, the operation section may further include a
display-position move button that receives movement of a display
position of the operation section on the display unit. This allows the
operator to move the operation section to any position in the display
area of the display unit to check an area hidden by the operation sectio5 n
in the display area.
[0099] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may have: a first mode of changing the
clearing limit with the first input section and the second input section
10 and causing the display unit to display the clearing limit changed; and a
second mode of changing the clearing limit so as to remove or not to
remove the yarn defect corresponding to an area touched among a
plurality of areas constituting the two-dimensional field and causing the
display unit to display the clearing limit changed. This allows the
15 operator to change the clearing limit with the operation section, and also
allows the operator to change the clearing limit on the basis of area
designation in the two-dimensional field.
[0100] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may have: a first mode of changing the
20 clearing limit with the first input section and the second input section
and causing the display unit to display the clearing limit changed; and a
second mode of causing the display unit to display an area touched
among a plurality of areas constituting the two-dimensional field such
that whether to remove or not to remove the yarn defect corresponding
25 to the area touched becomes distinguishable. This allows the operator
to change the clearing limit with the operation section, and also allows
32
the operator to change a clearing area on the basis of area designation in
the two-dimensional field.
[0101] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may cause the display unit to display
the clearing limit changed and also the clearing limit before bein5 g
changed. This allows the operator to compare the clearing limit
changed with the clearing limit before being changed.
[0102] In the clearing-limit setting device according to one aspect of the
present disclosure, the processor may acquire yarn defect data indicating
10 the length and the thickness of the yarn defect, calculate a first yarn
processing result based on the yarn defect data and the clearing limit
before being changed, calculate a second yarn processing result based
on the yarn defect data and the clearing limit changed, and cause the
display unit to display the first yarn processing result and the second
15 yarn processing result. This allows the operator to compare the first
yarn processing result with the second yarn processing result to evaluate
each of the clearing limit before being changed and the clearing limit
changed.
[0103] In the clearing-limit setting device according to one aspect of the
20 present disclosure, the processor may set the clearing limit before being
changed or the clearing limit changed as a new clearing limit. This
allows the operator to set the clearing limit before being changed or the
clearing limit changed as a new clearing limit.
[0104] A yarn winding machine according to one aspect of the present
25 disclosure includes: a yarn supplying section that supplies yarn; a
winding section that winds the yarn and forms a package; a yarn
33
monitoring section that monitors the yarn between the yarn supplying
section and the winding section, and detects a yarn defect; a yarn
joining section that, when the yarn has been cut to remove the yarn
defect detected by the yarn monitoring section, performs splicing
operation of splicing the yarn on the yarn supplying section side and th5 e
yarn on the winding section side; and the clearing-limit setting device
described above.
[0105] This yarn winding machine includes the clearing-limit setting
device described above, and thus can remove a yarn defect
10 appropriately.
[0106] According to the present disclosure, it is possible to provide the
