FIG. 3 is a diagram illustrating an example of a display screen of operating conditions. -
FIG. 4 is a diagram illustrating an example of an operation mode selection screen. - With reference to the accompanying drawings, the following describes an exemplary embodiment of the present invention in detail. In the description of the drawings, identical or equivalent constituent elements are denoted by identical reference signs, and redundant explanations are omitted.
- As illustrated in
FIG. 1 , an automatic winder (a yarn winding machine) 1 includes a plurality ofyarn winding units 3 arranged side by side, a machine control device (a control device) 5, and adoffer 7. - The
machine control device 5 is capable of communicating with each of theyarn winding units 3. An operator of theautomatic winder 1 can collectively manage theyarn winding units 3 by operating themachine control device 5 as appropriate. On themachine control device 5, a display operating unit (receiving unit) 5a is provided. Thedisplay operating unit 5a receives input of various conditions and displays various types of information. Thedisplay operating unit 5a is a liquid crystal display and displays an operation screen as a touch panel, for example. As will be described later, the operator inputs operating conditions of theyarn winding units 3 via thedisplay operating unit 5a. - The
yarn winding unit 3 unwinds yarn Y from a supply yarn bobbin SB and winds it around a winding bobbin WB while traversing. Thus, theyarn winding unit 3 forms a package P. Thedoffer 7 travels, when the package P is fully wound (in a state in which a predetermined amount of yarn is wound) in oneyarn winding unit 3, to the position of saidyarn winding unit 3, and removes the fully wound package P and sets an empty winding bobbin WB. - As illustrated in
FIG. 2 , theyarn winding unit 3 includes a unit controller (a control device) 10, ayarn feeder 12, and awinding apparatus 14. Theunit controller 10 includes a central processing unit (CPU) and a read only memory (ROM), for example. In the ROM, a program for controlling each constituent of theyarn winding unit 3 is stored. The CPU executes the program stored in the ROM. Theunit controller 10 is communicably connected to various units of theyarn winding unit 3 and controls the operation of each unit. - The
yarn feeder 12 is a support mechanism that supports the supply yarn bobbin SB placed on a transportation tray (not depicted) at a predetermined position. The yarn Y is unwound from the supply yarn bobbin SB supported by theyarn feeder 12 and is drawn out. As a result, theyarn feeder 12 supplies the yarn Y. Theyarn feeder 12 is not limited to the transportation tray type, and may be a magazine type, for example. - The
winding apparatus 14 includes acradle 16 and a windingdrum 18. Thecradle 16 has a pair of rotary support portions (not depicted) . Thecradle 16 rotatively supports the winding bobbin WB (or the package P), by sandwiching the winding bobbin WB with the rotary support portions . Thecradle 16 can be switched between a state in which the supporting package P is brought into contact with thewinding drum 18 and a state in which the package P is separated from thewinding drum 18. - The
winding drum 18 traverses the yarn Y on the surface of the package P and rotates the package P. The windingdrum 18 is rotationally driven by a drum drive motor (not depicted) . The windingdrum 18 is rotationally driven in a state in which the outer circumference of the package P is in contact. Thus, the windingdrum 18 causes the package P to passively rotate. On the outer circumferential surface of the windingdrum 18, a helical traverse groove is formed. The yarn Y unwound from the supply yarn bobbin SB is wound around the surface of the package P while being traversed in a certain width by the traverse groove. This makes it possible to form the package P having a certain winding width. The configuration of the windingapparatus 14 is not limited thereto. For example, the traverse groove may be not formed on the windingdrum 18, and the windingapparatus 14 may be configured so that the yarn Y is traversed by a traverse member (for example, an arm, a belt, or a vane) provided separately from the windingdrum 18. Alternatively, the windingapparatus 14 may be configured so that the package P is not passively rotated but directly rotationally driven. - Each
yarn winding unit 3 includes, in order from theyarn feeder 12 side in a yarn path between theyarn feeder 12 and the windingapparatus 14, anunwinding assisting device 20, atension applying device 22, atension detection device 24, ayarn joining device 26, and ayarn monitoring device 28. In the vicinity of theyarn joining device 26, afirst catching device 30 and asecond catching device 32 are arranged. - The unwinding assisting
device 20 is provided with a regulatingmember 21 that assists unwinding of the yarn from the supply yarn bobbin SB. The unwinding assistingdevice 20 may be not provided with the regulatingmember 21. - The
tension applying device 22 applies a predetermined tension to the running yarn Y. In the present embodiment, thetension applying device 22 is of a gate type in which movable comb teeth are arranged with respect to fixed comb teeth. The configuration of thetension applying device 22 is not limited to the gate type, and it may be a tension applying device of other methods such as a disk type, for example. - The
tension detection device 24 detects the tension of the running yarn Y between theyarn feeder 12 and the windingapparatus 14. - The
yarn joining device 26, when the yarn Y is in a state of being severed between theyarn feeder 12 and the windingapparatus 14 for some reason, joins the yarn Y (lower yarn) of theyarn feeder 12 side and the yarn Y (upper yarn) of the windingapparatus 14 side. Theyarn joining device 26 is configured as a splicer device that twists together the yarn ends by a swirl airflow generated by compressed air, for example. The configuration of theyarn joining device 26 is not limited thereto, and it may be a disk-type splicer or a knotter. - The
yarn monitoring device 28 monitors (detects) the state of the yarn Y wound by the windingapparatus 14. Theyarn monitoring device 28 acquires, as yarn quality of the yarn Y, information concerning at least any of a yarn defect of the yarn Y, hairiness of the yarn Y, and unevenness in thickness of the yarn Y. Theyarn monitoring device 28 detects, as the yarn defect, the thickness abnormality of the yarn Y and/or a foreign object that is contained in the yarn Y, for example. Furthermore, theyarn monitoring device 28 detects the yarn breakage, that is, the presence of the yarn Y in the yarn path of the yarn Y, and the like. Theyarn monitoring device 28 has a slit on the yarn path of the yarn Y, and monitors the yarn Y passing through the slit with a sensor (not depicted). In theyarn monitoring device 28, a cutter (not depicted) for cutting the yarn Y is provided. Theyarn monitoring device 28 activates the cutter, when the yarn defect of the yarn Y is detected. The cutter may be provided in a place other than theyarn monitoring device 28. As the sensor to be provided in theyarn monitoring device 28, an optical type, a capacitance type, a triboelectric type, or another type can be employed. - The
first catching device 30 catches the upper yarn when the yarn Y is in a severed state. Thefirst catching device 30 is, by the control of theunit controller 10, able to swivel (move) from a standby position (solid lines, inFIG. 2 ) of theyarn feeder 12 side to a catching position (dashed lines, inFIG. 2 ) of the windingapparatus 14 side. Thefirst catching device 30 is connected to a negative pressure source (not depicted) and generates a suction flow. With this configuration, by catching the upper yarn at the catching position and returning to the standby position, an upper-yarn suction catching portion 33 guides the upper yarn to theyarn joining device 26. The configuration of the first catchingdevice 30 is not limited thereto. - The
second catching device 32 is, by the control of theunit controller 10, able to swivel (move) from a standby position (a solid line, inFIG. 2 ) of theyarn feeder 12 side to a catching position (a dashed line, inFIG. 2 ) of the windingapparatus 14 side. Thesecond catching device 32 is connected to a negative pressure source (not depicted) and generates a suction flow. With this configuration, thesecond catching device 32 catches the lower yarn and guides it to theyarn joining device 26. The configuration of thesecond catching device 32 is not limited thereto. - As in the foregoing, the
yarn winding unit 3 winds the yarn Y onto the winding bobbin WB and forms the package P. In yarn splicing operation in theyarn joining device 26, the yarn Y of the windingapparatus 14 side is caught by the first catchingdevice 30 and the yarn Y of theyarn feeder 12 side is caught by thesecond catching device 32. The yarn Y caught by the first catchingdevice 30 and the yarn Y caught by thesecond catching device 32 are guided to theyarn joining device 26. At this time, the yarn Y is positioned at the slit of theyarn monitoring device 28. Theyarn joining device 26 performs yarn splicing of the introduced pieces of the yarn Y. - Next, the operation of the
unit controller 10 will be described further. Theunit controller 10 controls the operation of theyarn winding unit 3, on the basis of the state of the yarn Y detected by theyarn monitoring device 28 and the operating conditions of theyarn winding unit 3 so that the yarn quality of the yarn Y wound by the windingapparatus 14 satisfies target quality (results in the target quality) . The operating conditions of eachyarn winding unit 3 are input to themachine control device 5 via thedisplay operating unit 5a. Upon receiving this input, themachine control device 5 instructs theunit controller 10 of eachyarn winding unit 3 to operate under the input operating conditions. - In the
display operating unit 5a, displayed is asetting screen 41 of the operating conditions as illustrated inFIG. 3 . On thesetting screen 41, a plurality of lots oflot 1,lot 2,lot 3,lot 4, ... are displayed. The lot is a set (group) of a plurality of setting items set as the operating conditions of theyarn winding unit 3. As any of the existing lots is selected on thesetting screen 41 or a new lot is created, the operating conditions of theyarn winding unit 3 are set. - Each lot includes, as the setting items, a count type, a count, and a yarn type of the yarn Y, a weight and a fixed yarn length of the package P, and a type and a length of the supply yarn bobbin SB and the like. In addition, each lot further includes an operation mode as one of the setting items. As the operation mode, a quality emphasis mode, a balance mode, a productivity emphasis mode, and a manual mode are prepared. On each lot, any of a plurality of operation modes of the quality emphasis mode, the balance mode, the productivity emphasis mode, and the manual mode is assigned. In each of those operation modes, target quality is set. The operator can select the operation mode used in each lot by touching (pressing down) the inside of a frame of the operation mode of each lot displayed on the
setting screen 41. - The quality emphasis mode, the balance mode, and the productivity emphasis mode are the modes set in accordance with which of the yarn quality and productivity is emphasized. The quality emphasis mode is a mode that operates with emphasis on the yarn quality rather than the productivity. The productivity emphasis mode is a mode that operates with emphasis on the productivity rather than the yarn quality. The balance mode is a mode that operates without biasing to either of the yarn quality and the productivity. The manual mode is a mode that operates at a winding speed set by the operator.
- Among the quality emphasis mode, the balance mode, and the productivity emphasis mode, the target quality of the quality emphasis mode is the highest, the target quality of the balance mode is the second highest, and the target quality of the productivity emphasis mode is the lowest. The target quality, for example, is a target range having a predetermined scope, but may be a target numerical value.
- Furthermore, among the quality emphasis mode, the balance mode, and the productivity emphasis mode, the winding speed in the productivity emphasis mode is the fastest, the winding speed in the balance mode is the second fastest, and the winding speed in the quality emphasis mode is the slowest.
- In detail, when the operator touches (presses down) the inside of the frame of the operation mode of each lot on the
setting screen 41, aselection screen 43 of the operation mode as illustrated inFIG. 4 is displayed on thedisplay operating unit 5a. On theselection screen 43,buttons 44 to 47 corresponding to each of the quality emphasis mode, the balance mode, the productivity emphasis mode, and the manual mode are displayed. The operator can select (switch) the operation mode of theyarn winding unit 3 by touching the inside of the frames of thebuttons 44 to 47. In the example inFIG. 3 andFIG. 4 , the quality emphasis mode selected as the operation mode of thelot 1 is colored and displayed. - When a lot for which an operation mode is selected is set as an operating condition, the
unit controller 10 controls the operation of theyarn winding unit 3 so that the yarn quality of the yarn Y wound by the windingapparatus 14 satisfies the target quality corresponding to the relevant operation mode. - In more detail, the
unit controller 10 controls the winding speed at which the windingapparatus 14 winds the yarn Y so that the yarn quality of the yarn Y wound by the windingapparatus 14 satisfies the target quality corresponding to the operation mode. Theunit controller 10 controls the winding speed by controlling the rotation speed of the drum drive motor that drives the windingdrum 18. When the winding speed is lowered, the hairiness of the yarn Y may be reduced, for example. That is, when the winding speed is lowered, the yarn quality of the yarn Y may be improved. Theunit controller 10 maintains the winding speed, when the yarn quality of the yarn Y detected by theyarn monitoring device 28 satisfies the target quality. On the other hand, when the yarn quality of the yarn Y detected by theyarn monitoring device 28 is lower than the target quality, theunit controller 10 decreases the winding speed. When the yarn quality of the yarn Y detected by theyarn monitoring device 28 is higher than the target quality, theunit controller 10 increases the winding speed. Accordingly, while the winding speed is maintained when the yarn quality of the yarn Y satisfies the target quality, the winding speed is changed so that the yarn quality of the yarn Y approaches the target quality when the yarn quality of the yarn Y is out of the target range. As a result, the yarn quality of the yarn Y satisfies the target quality corresponding to the operation mode. - Moreover, the
unit controller 10 controls the tension of the yarn Y so that the yarn quality of the yarn Y wound by the windingapparatus 14 satisfies the target quality corresponding to the operation mode. Theunit controller 10 changes the tension of the yarn Y by controlling the operation of thetension applying device 22 on the basis of the tension of the yarn Y detected by thetension detection device 24. When the tension of the yarn Y is weakened, the hairiness of the yarn Y may be reduced, for example. That is, when the tension of the yarn Y is weakened, the yarn quality of the yarn Y may be improved. Theunit controller 10 maintains the tension of the yarn Y, when the yarn quality of the yarn Y detected by theyarn monitoring device 28 satisfies the target quality. On the other hand, when the yarn quality of the yarn Y detected by theyarn monitoring device 28 is lower than the target quality, theunit controller 10 weakens the tension of the yarn Y. Furthermore, when the yarn quality of the yarn Y detected by theyarn monitoring device 28 is higher than the target quality, theunit controller 10 strengthens the tension of the yarn Y. Accordingly, while the tension of the yarn Y is maintained when the yarn quality of the yarn Y satisfies the target quality, the tension of the yarn Y is changed so that the yarn quality of the yarn Y approaches the target quality when the yarn quality of the yarn Y is out of the target range. As a result, the yarn quality of the yarn Y satisfies the target quality corresponding to the operation mode. - When the manual mode is selected as the operation mode on the
selection screen 43, the operator inputs a target value of the winding speed (1500 m/min, inFIG. 4 ) on an input screen of thedisplay operating unit 5a. In this case, theunit controller 10 controls the winding speed so that the winding speed is of the target value. Accordingly, in the manual mode, the winding speed is of the target value that the operator sets, and the yarn quality of the yarn Y results in the quality corresponding to the target value. Each of the above-described control may be executed by not theunit controller 10 but themachine control device 5, or may be executed by cooperation (role sharing) of theunit controller 10 and themachine control device 5. - As in the foregoing, in the
automatic winder 1, thedisplay operating unit 5a configured to receive a setting of target quality of the yarn Y to be wound by the windingapparatus 14 is included, and thus, as the user sets desired target quality via thedisplay operating unit 5a, it is possible to obtain the package P of yarn quality that satisfies the desired target quality. - Furthermore, in the
automatic winder 1, theunit controller 10 controls the operation of theyarn winding unit 3 so that the yarn quality of the yarn Y to be wound by the windingapparatus 14 results in target quality that thedisplay operating unit 5a has received. This makes it possible to surely obtain a package of yarn quality that satisfies the desired target quality. - In the
automatic winder 1, theunit controller 10 acquires information concerning the state of the yarn Y detected by theyarn monitoring device 28 from theyarn monitoring device 28, and controls the operation of theyarn winding unit 3 so that the yarn quality based on the information concerning the state of the yarn Y detected by theyarn monitoring device 28 results in the target quality. This makes it possible, by utilizing the information that theyarn monitoring device 28 has, to obtain a package of yarn quality that satisfies the desired target quality. - In the
automatic winder 1, theunit controller 10 controls the winding speed at which the windingapparatus 14 winds the yarn Y and the tension of the yarn Y to be wound by the windingapparatus 14 so that the yarn quality satisfies the target quality. This makes it possible, by changing the operation of theyarn winding unit 3 that has a great influence on the yarn quality, to surely obtain the package P that satisfies the desired target quality. - In the
automatic winder 1, the yarn quality is a yarn defect of the yarn Y, hairiness of the yarn Y, and unevenness in thickness of the yarn Y. This makes it possible to surely obtain the package P having the desired number of yarn defects, the amount of hairiness, and the degree of unevenness in thickness. - In the
automatic winder 1, theyarn winding unit 3 has a plurality of kinds of operation modes, and the target quality is set in each of the operation modes. This makes it possible to easily obtain the package P of yarn quality that satisfies the desired target quality by merely selecting the operation mode. - As in the foregoing, one exemplary embodiment of the present invention has been described, but the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the
unit controller 10 controls the winding speed and the tension so that the yarn quality of the yarn Y satisfies the target quality. However, theunit controller 10 may, in addition, change a threshold value on the determination of the yarn defect detection by theyarn monitoring device 28 so that the yarn quality of the yarn Y satisfies the target quality. The threshold value on the determination of the yarn defect detection is a clearing limit, for example. The clearing limit is made up having, in the two-dimensional field that has each of the length and the thickness of the yarn defect as a coordinate axis, a boundary line for determining whether to remove the yarn defect. Theunit controller 10 causes theyarn monitoring device 28 to change the above-described boundary line in accordance with the yarn quality of the yarn Y detected by theyarn monitoring device 28, for example. In this case, it is possible to further surely obtain the package P of the yarn quality corresponding to the operating conditions of theyarn winding unit 3. - In the above-described embodiment, the
unit controller 10 controls both the winding speed and the tension of the yarn Y, but may control only one of the winding speed and the tension of the yarn Y. In the above-described embodiment, the yarn quality is both the hairiness of the yarn Y and the unevenness in thickness, but may be one of the hairiness of the yarn Y and the unevenness in thickness. - In the above-described embodiment, four kinds of operation modes are prepared, but the prepared operation modes are not limited thereto. For example, there may be no balance mode and/or manual mode, and at least the quality emphasis mode and the productivity emphasis mode may be prepared. In this case, it is preferable that the target quality that is set in the quality emphasis mode be higher than the target quality that is set in the productivity emphasis mode. It is preferable that the winding speed that is set in the productivity emphasis mode be faster than the winding speed that is set in the quality emphasis mode.
- In the above-described embodiment, a plurality of kinds of operation modes are prepared in advance and the target quality corresponding to the operation mode is set by selecting a desired one out of the prepared operation modes, but the
yarn winding unit 3 does not necessarily need to have a plurality of kinds of operation modes. In this case, the operator may, on thesetting screen 41, input (set) a desired target value/target grade of yarn quality of the yarn Y as the target quality, for example. As the target value, the number of yarn defects per predetermined length (for example, 100 km), the amount of hairiness of the yarn, or the degree of unevenness in yarn thickness may be input, for example. As the target grade, a known yarn quality level may be input, for example. Thedisplay operating unit 5a (receiving unit) may be configured to receive, as a setting of the target value or the target grade (setting of the target quality), an input of a numerical value, a character, or a symbol by the operator (user) . The input of the target grade may be to select a desired one out of the yarn quality in a plurality of levels prepared in advance. - In the above-described embodiment, the
yarn winding unit 3 is configured to unwind the yarn Y from the supply yarn bobbin SB and to form the package P, but may be configured to unwind the yarn Y from the package P and to form the package P. That is, theyarn winding unit 3 may be configured to make the fully wound package P from a plurality of packages P in which the amount of winding is below a specified amount. Alternatively, theyarn winding unit 3 may be configured to rewind from the fully wound package P (a dyed package P) into the package P. In this case, theyarn feeder 12 is a support mechanism that supports the package P at a predetermined position, and may be configured to supply the yarn Y from the package P. That is, theyarn feeder 12 may be configured to supply the yarn from a yarn winding body on which the yarn is wound around such as a supply yarn bobbin or a supply yarn package. - In the above-described embodiment and modifications, the operation (for example, at least one of the winding speed and the tension of the yarn Y) of the
yarn winding unit 3 is controlled so that the yarn quality based on the state of the yarn Y detected by theyarn monitoring device 28 results in the set target quality. That is, feedback control (for example, increasing and decreasing of at least one of the winding speed and the tension) is executed on the basis of the current state of the yarn Y. However, not the feedback control but the control (control without feedback) that simply sets target quality of the yarn Y to be wound by the windingapparatus 14 and that merely controls the operation of theyarn winding unit 3 to satisfy the set target quality may be executed. - Specifically, as the control without feedback, the yarn winding unit may be controlled so that the winding speed is slower than that of the standard when the quality emphasis mode is set, and the yarn winding unit may be controlled so that the winding speed is faster than that of the standard when the productivity emphasis mode is set.
- The setting of the target quality may be received by the
display operating unit 5a provided on themachine control device 5 as in the above-described embodiment, or may be received by a receiving unit provided at a place other than themachine control device 5. The configuration of the receiving unit may be a touch panel as in the foregoing, but is not limited thereto and may be a keyboard, an input key, or a push button, for example. When the yarn winding machine is configured to be able to communicate with a mobile terminal or other external devices, the receiving unit may be an input unit (reception unit) that receives input information from the external device and the like. - According to an aspect of the present invention, it is possible to obtain a package of yarn quality that satisfies desired target quality.
