For example, when a yarn defect determined to be excessive hairiness yarn has been detected from all pieces of detection data of the respective yarn monitoring devices 45, the control device 41 determines that an abnormal stop of a blower has occurred in the spinning frame 3. In this case, the control device 41 determines that the spinning frame 3 has abnormality, and acquires, as abnormality information, information indicating that an abnormal stop has occurred in a negative-pressure generating device (blower) configured to supply negative pressure to a mechanism configured to reduce fuzz by using negative pressure of the spinning frame 3.

FIG. 1 , ayarn winding system 1 includes aroving frame 2, aspinning frame 3, anautomatic winder 4, and abobbin transfer device 5. Theroving frame 2 generates roved yarn from a sliver, and winds the roved yarn to form a roved yarn bobbin. Thespinning frame 3 generates yarn from the roved yarn, and winds the yarn to form ayarn supply bobbin 11. Theautomatic winder 4 winds the yarn from theyarn supply bobbin 11 to form a package. Thebobbin transfer device 5 transfers theyarn supply bobbin 11 from thespinning frame 3 to theautomatic winder 4, and transfers an empty bobbin 12 (bobbin around which yarn is not wound) from theautomatic winder 4 to thespinning frame 3. Thebobbin transfer device 5 is provided with a bobbin preparation device and a residual yarn processing device, for example. The bobbin preparation device performs preliminary preparation for theautomatic winder 4 to process the yarn of theyarn supply bobbin 11. When yarn remains on thebobbin 12 that has been discharged from theyarn supply bobbin 11, the residual yarn processing device removes the yarn to form anempty bobbin 12. For this purpose, thebobbin transfer device 5 has a complicated transfer path having many curves. - The
yarn supply bobbin 11 and theempty bobbin 12 are transferred in a manner being set onrespective trays 6. As depicted inFIG. 2 , each of thetrays 6 has a disk-like base portion 61, apin 62 protruding upward from thebase portion 61, and a radio frequency (RF) tag (storage unit) 63 embedded in thebase portion 61.

In thedrafting device 33, theback roller pair 33a, themiddle roller pair 33b, and thefront roller pair 33c are rotated at a predetermined speed ratio, whereby a rovedyarn 13 that has been unwound from a roved yarn bobbin is drafted. - The twisting
device 34 includes aspindle shaft 35, aring rail 36, aring 37, and atraveller 38. Thespindle shaft 35 holds thebottom portion 12a of abobbin 12 with thetop portion 12b of thebobbin 12 facing upward, and rotates thebobbin 12. Thering rail 36 is movable in the axial direction of thebobbin 12. Thering 37 is fixed to thering rail 36. Thetraveller 38 is supported by thering 37, and is movable along thering 37. - In the
twisting device 34, rovedyarn 13 that has been drafted by the draftingdevice 33 is inserted into a space between thering 37 and thetraveller 38, and an end portion of the rovedyarn 13 is fixed to thebobbin 12. In this state, when thespindle shaft 35 rotates thebobbin 12, thetraveller 38 moves along thering 37 in a manner being pulled by the rovedyarn 13. At this time, thering rail 36 gradually moves from thebottom portion 12a side to thetop portion 12b side while reciprocating within a predetermined range along the axial direction of thebobbin 12.

device 43 includes acradle 43a and a windingdrum 43b. Thecradle 43a supports apackage 15. The windingdrum 43b rotates thepackage 15 while traversing theyarn 14. Thus, theyarn 14 is wound from ayarn supply bobbin 11 set at a predetermined position to form thepackage 15. Thetension applying device 44 applies a predetermined tension to theyarn 14 that is travelling from theyarn supply bobbin 11 to thepackage 15. - The
yarn monitoring device 45 monitors the travellingyarn 14 to detect the state of theyarn 14 including a yarn defect (thickness abnormality ofyarn 14, mixing of foreign matter intoyarn 14, etc.). When a yarn defect has been detected, theyarn 14 is cut by a cutter separately provided. When theyarn 14 has been cut, the upperyarn catching device 46 catches a yarn end of theyarn 14 on thepackage 15 side, and guides the yarn end to thesplicing device 48. When theyarn 14 has been cut, the loweryarn catching device 47 catches a yarn end of theyarn 14 on theyarn supply bobbin 11 side, and guides the yarn end to thesplicing device 48. Thesplicing device 48 splices the yarn ends that have been guided by the upperyarn catching device 46 and the loweryarn catching device 47 to each other. - As depicted in
FIG. 1 , thebobbin transfer device 5 includes anRF writer 51. When ayarn supply bobbin 11 is transferred from thespinning frame 3 to theautomatic winder 4, theRF writer 51 writes information on theyarn supply bobbin 11 on theRF tag 63 of thetray 6 on which theyarn supply bobbin 11 is set. The information on theyarn supply bobbin 11 includes unit identification information for identifying aspinning unit 32 that has formed the yarn supply bobbin 11 (identification information) and doffing information for identifying timing of simultaneous doffing. TheRF writer 51 may be provided to an exit of thespinning frame 3 in the transfer direction of theyarn supply bobbin 11. Alternatively, theRF writer 51 may be provided to everyspinning unit 32. - When the
yarn supply bobbin 11 has been set on thewinder unit 42 of theautomatic winder 4, the information written on theRF tag 63 by theRF writer 51 is read by an RF reader (reading unit) 49 provided to each of thewinder units 42, and is transmitted to thecontrol device 41 of theautomatic winder 4. Based on this information, thecontrol device 41 can identify thespinning unit 32 that has formed theyarn supply bobbin 11 and the timing of simultaneous doffing for theyarn supply bobbin 11 set on thewinder unit 42. - The following describes main parts of the
yarn winding system 1 in detail with reference toFIG. 5 . - As depicted in
FIG. 5 , in each of thewinder units 42, the correspondingyarn monitoring device 45 detects the state of travellingyarn 14, and outputs the detected detection data to thecontrol device 41. The detection data includes yarn defect detection data on a yarn defect, foreign matter detection data on foreign matter, yarn color defect detection data on a yarn color defect, apparent thickness data on apparent yarn thickness indices, Super Spectron data on Super Spectron, hairiness data, and apparent thickness variation coefficient data on CV% (coefficient of variation) of apparent yarn thickness.

RF reader 49 reads, in a noncontact manner, at least unit identification information that is written on theRF tag 63 of thetray 6 by the RF writer 51 (seeFIG. 1 ). TheRF reader 49 outputs the read unit identification information to thecontrol device 41. The unit identification information includes inspector information on the machine number of aspinning unit 32 that has formed ayarn supply bobbin 11 supported by thetray 6. The unit identification information herein is written on theRF tag 63 in a manner described below, for example. Specifically,yarn supply bobbins 11 that have been simultaneously doffed in thespinning frame 3 are set ontrays 6, and then pass through theRF writer 51 in the same order as the order in which thespinning units 32 are aligned. Thus, theRF writer 51 identifies aspinning unit 32 that has formed ayarn supply bobbin 11 by counting the order of each of theyarn supply bobbins 11 passing therethrough, and writes, on theRF tag 63, unit identification information indicating by which spinningunit 32 the yarn supply bobbin has been formed. - The
automatic winder 4 includes thecontrol device 41 and atransmission unit 41x. Thecontrol device 41 is an electronic control unit having a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM), for example. Thecontrol device 41 loads a program stored in the ROM into the RAM, and causes the CPU to execute the program, thereby performing various controls. Thecontrol device 41 may include a plurality of electronic control units. Thecontrol device 41 outputs information on monitoring results of theyarn monitoring devices 45 to thetransmission unit 41x. - The
control device 41 is a first abnormality information acquisition unit configured to acquire abnormality information of the previous step machine. Based on the detection data output from each of theyarn monitoring devices 45 and/or the unit identification information output from thecorresponding RF reader 49, thecontrol device 41 conducts an abnormality check described below, and acquires the result as the abnormality information. - Specifically, the
control device 41 checks and identifies aspinning unit 32 in which abnormality has occurred among the spinningunits 32. For example, thecontrol device 41 associates the unit identification information with the detection data of each of theyarn monitoring devices 45, and determines which spinningunit 32 has formed ayarn supply bobbin 11 the state of yarn of which is indicated by each of the detection data. Subsequently, for example, when the yarn defect detection data includes a yarn defect that occurs repeatedly and continuously (i.e., when a yarn defect occurring periodically, not a yarn defect occurring accidentally, is included), aspinning unit 32 associated with this yarn defect detection data (textile alarm) is identified as a spinning unit having abnormality. In this case, thecontrol device 41 determines that thespinning frame 3 has abnormality, and acquires information indicating that the identified spinningunit 32 has abnormality as abnormality information. - When the same yarn defect has been detected from all pieces of detection data of the respective
yarn monitoring devices 45, thecontrol device 41 determines that abnormality that is common to the spinning units 32 (extensive abnormality in the spinning frame 3) has occurred. For example, when a yarn defect determined to be excessive hairiness yarn has been detected from all pieces of detection data of the respectiveyarn monitoring devices 45, thecontrol device 41 determines that an abnormal stop of a blower has occurred in thespinning frame 3. In this case, thecontrol device 41 determines that thespinning frame 3 has abnormality, and acquires, as abnormality information, information indicating that an abnormal stop has occurred in a negative-pressure generating device (blower) configured to supply negative pressure to a mechanism configured to reduce fuzz by using negative pressure of thespinning frame 3. - The
control device 41 also checks abnormality of theroving frame 2. In most cases, when a malfunction has occurred in a certainroving unit 22, influence of this malfunction is exerted on a plurality of spinningunits 32 to which thisroving unit 22 supplies roved yarn bobbins. Thus, for example, when thecontrol device 41 has identified a plurality of spinningunits 32 in which abnormality has occurred, if yarn defects ofyarns 14 spun by these spinningunits 32 are the same and one or moreroving units 22 supplying roved yarn bobbins to these spinningunits 32 are the same, the control device determines that abnormality has occurred in the same one or moreroving units 22. In this case, thecontrol device 41 determines that theroving frame 2 has abnormality, and acquires, as abnormality information, information indicating that abnormality has occurred in the one or moreroving units 22. Thecontrol device 41 outputs the acquired abnormality information to thetransmission unit 41x. - The
transmission unit 41x is a part configured to transmit information from theautomatic winder 4 to theroving frame 2 and thespinning frame 3. Thetransmission unit 41x transmits the abnormality information output by thecontrol device 41 to a later-describedreceiving unit 21x of theroving frame 2 and a later-describedreceiving unit 31x of thespinning frame 3 as information on monitoring results of theyarn monitoring devices 45. Transmission by thetransmission unit 41x to the receivingunit 21x and the receivingunit 31x may be performed through wired communication using a cable, for example, or may be performed through wireless communication. When the transmission by thetransmission unit 41x is performed through wireless communication, radio waves, infrared rays, or light may be used as conveyance media. InFIG. 5 , thetransmission unit 41x and thecontrol device 41 are illustrated as separate elements. However, thetransmission unit 41x may be included in thecontrol device 41. In other words, thetransmission unit 41x may be a communication function implemented in thecontrol device 41. - The
spinning frame 3 includes the receivingunit 31x, thecontrol device 31, and anotification unit 31y. The receivingunit 31x receives the abnormality information transmitted from thetransmission unit 41x of theautomatic winder 4 as information on monitoring results of theyarn monitoring devices 45. The receivingunit 31x outputs the received abnormality information to thecontrol device 31. - The
control device 31 is an electronic control unit including a CPU, a ROM, and a RAM. Thecontrol device 31 loads a program stored in the ROM into the RAM, and causes the CPU to execute the program, thereby performing various controls. Thecontrol device 31 may include a plurality of electronic control units. According to the abnormality information output from the receivingunit 31x, thecontrol device 31 controls operation of thenotification unit 31y. - According to the abnormality information received, the
notification unit 31y notifies the operator of abnormality in thespinning frame 3. Thenotification unit 31y notifies the operator of abnormality locations such as aspinning unit 32 having abnormality and/or extensive abnormality in thespinning frame 3 to warn and alert the operator. Thenotification unit 31y includes at least one of a display unit configured to display an alarm, a warning light, and a speaker. InFIG. 5 , the receivingunit 31x and thenotification unit 31y are illustrated as elements separate from thecontrol device 31. However, at least one of the receivingunit 31x and thenotification unit 31y may be included in thecontrol device 31. In other words, the receivingunit 31x may be a communication function implemented in thecontrol device 31, and thenotification unit 31y may be a notification function implemented in thecontrol device 31. - The
roving frame 2 includes the receivingunit 21x, thecontrol device 21, and anotification unit 21y. The receivingunit 21x receives the abnormality information transmitted from thetransmission unit 41x of theautomatic winder 4 as information on the monitoring result of theyarn monitoring device 45. The receivingunit 21x outputs the received abnormality information to thecontrol device 21. - The
control device 21 is an electronic control unit including a CPU, a ROM, and a RAM. Thecontrol device 21 loads a program stored in the ROM into the RAM, and causes the CPU to execute the program, thereby performing various controls. Thecontrol device 21 may include a plurality of electronic control units. According to the abnormality information output from the receivingunit 21x, thecontrol device 21 controls operation of thenotification unit 21y. - According to the abnormality information received, the
notification unit 21y notifies the operator of abnormality in theroving frame 2. Thenotification unit 21y notifies the operator of abnormality locations such as aroving unit 22 having abnormality and/or extensive abnormality in theroving frame 2 to warn and alert the operator. Thenotification unit 21y includes at least one of a display unit configured to display an alarm, a warning light, and a speaker. InFIG. 5 , the receivingunit 21x and thenotification unit 21y are illustrated as elements separate from thecontrol device 21. However, at least one of the receivingunit 21x and thenotification unit 21y may be included in thecontrol device 21. In other words, the receivingunit 21x may be a communication function implemented in thecontrol device 21, and thenotification unit 21y may be a notification function implemented in thecontrol device 21. - The following describes a yarn winding method performed by the
yarn winding system 1. In the following description, one example of processes performed in the yarn winding method related to communication between thetransmission unit 41x and the receivingunit 21x and between the transmission unit and the receivingunit 31x will be described with reference to a sequence diagram ofFIG. 6 . - As depicted in
FIG. 6 , in theautomatic winder 4, each of theRF readers 49 reads and acquires unit identification information written on theRF tag 63 of thetray 6 by the RF writer 51 (S1). Eachyarn monitoring device 45 detects the state of travellingyarn 14, and acquires detection data on at least part ofyarn 14 wound by the corresponding yarn supply bobbin 11 (S2). Based on the detection data and/or the unit identification information, thecontrol device 41 conducts the abnormality check described above (S3). - As a result of the abnormality check at S3 above, if it is determined that the
spinning frame 3 has abnormality (Yes at S4), abnormality information is transmitted from thetransmission unit 41x of theautomatic winder 4 to the receivingunit 31x of the spinning frame 3 (S5). As a result of the abnormality check at S3 above, if it is determined that theroving frame 2 has abnormality (Yes at S6), abnormality information is transmitted from thetransmission unit 41x of theautomatic winder 4 to the receivingunit 21x of the roving frame 2 (S7). Subsequently, for example, every time ayarn supply bobbin 11 is newly transferred to theautomatic winder 4, the respective processes described above are repeatedly performed. - In the
spinning frame 3, when the receivingunit 31x has received the abnormality information transmitted from thetransmission unit 41x of theautomatic winder 4, thenotification unit 31y outputs an alarm display (S11, S12). In theroving frame 2, the receivingunit 21x has received the abnormality information transmitted from thetransmission unit 41x of theautomatic winder 4, thenotification unit 21y outputs an alarm display (S21, S22). Subsequently, the alarm display of thenotification unit 31y is cleared by the operator's operation of thecontrol device 31. The alarm display of thenotification unit 21y is cleared by the operator's operation of thecontrol device 21. - As described in the foregoing, in the
yarn winding system 1, information on the monitoring result of each of theyarn monitoring devices 45 is transmitted from theautomatic winder 4 to thespinning frame 3 and/or theroving frame 2 as a previous step machine. Thus, in each of the previous step machines, based on the received information, for example, a quality defect ofyarn 14 that has been spun by the previous step machine, and consequently abnormality in the previous step machine can be grasped. In other words, abnormality that has occurred in a previous step machine can be grasped in the previous step machine in a timely manner. Consequently, in the event of abnormality, maintenance and/or adjustment of the previous step machine can be automatically performed in a timely manner, and quality ofyarn 14 can be improved immediately in the previous step machine. - In the
yarn winding system 1, thecontrol device 41 of theautomatic winder 4 acquires abnormality information on each of the previous step machines based on detection data detected by theyarn monitoring devices 45. The abnormality information is transmitted to the corresponding previous step machine by thetransmission unit 41x. Thus, in the previous step machine, the abnormality that has occurred can be grasped in a timely manner by receiving the abnormality information. - In the
yarn winding system 1, thetray 6 includes theRF tag 63 configured to store therein unit identification information. In theautomatic winder 4, the unit identification information of theRF tag 63 is read by the correspondingRF reader 49. In thecontrol device 41, based on detection data detected by each of theyarn monitoring devices 45 and unit identification information read by each of thecorresponding RF readers 49, aspinning unit 32 in which abnormality has occurred is identified. Subsequently, abnormality information on thisspinning unit 32 is transmitted from thetransmission unit 41x to the receivingunit 31x of thespinning frame 3. Thus, in thespinning frame 3, aspinning unit 32 in which abnormality has occurred can be grasped in a timely manner. - In the
yarn winding system 1, thecontrol device 41 of theautomatic winder 4 acquires abnormality information on abnormality that is common to a plurality of spinningunits 32, based on the detection data detected by theyarn monitoring devices 45. The abnormality information on abnormality that is common to the spinningunits 32 is transmitted from thetransmission unit 41x to the receivingunit 31x of thespinning frame 3. Thus, in thespinning frame 3, abnormality that is common to the spinningunits 32, such as an abnormal stop of the blower, for example, can be grasped in a timely manner. - In the
yarn winding system 1, theroving frame 2 includes thenotification unit 21y, and thespinning frame 3 includes thenotification unit 31y. Thus, the operator can be notified of abnormality that has occurred in theroving frame 2 and thespinning frame 3. - In the
yarn winding system 1, the detection data includes yarn defect detection data on a detected yarn defect. Thus, for example, when the yarn defect detection data is data (textile alarm) including a yarn defect that occurs repeatedly and continuously, thecontrol device 41 of theautomatic winder 4 determines that abnormality has occurred in the previous step machine, and can acquire the abnormality information. - The
yarn winding system 1 includes theroving frame 2 as a previous step machine. In this case, abnormality that has occurred in theroving frame 2 can be grasped in a timely manner in theroving frame 2 as a previous step machine. - The
automatic winder 4 includes theyarn monitoring devices 45 and thetransmission unit 41x configured to transmit information on monitoring results of theyarn monitoring devices 45 to theroving frame 2 and thespinning frame 3 as previous step machines. Thus, in theroving frame 2 and thespinning frame 3, based on the information on monitoring results of theyarn monitoring devices 45, abnormality that has occurred can be grasped in a timely manner. - The
spinning frame 3 is arranged for a previous step for theautomatic winder 4, and includes the receivingunit 31x configured to receive information on monitoring results of theyarn monitoring devices 45 of theautomatic winder 4 from theautomatic winder 4. In thespinning frame 3, based on the received information, abnormality that has occurred can be grasped in a timely manner. - The yarn winding method according to the present embodiment includes: the above-described S2 of, by the
yarn monitoring devices 45, detecting the state ofyarn 14 travelling in theautomatic winder 4 to acquire detection data; and the above-described S5 of transmitting information on monitoring results of theyarn monitoring devices 45 from theautomatic winder 4 to thespinning frame 3. By this yarn winding method, in thespinning frame 3, based on the information on monitoring results of theyarn monitoring devices 45, abnormality that has occurred can be grasped in a timely manner. - Although one embodiment has been described above, the present invention is not limited to the embodiment.
- In the embodiment, the abnormality check conducted by the
control device 41 of theautomatic winder 4 may be conducted by at least one of thecontrol device 21 of theroving frame 2 and thecontrol device 31 of thespinning frame 3 as described below, for example. - Specifically, in the
automatic winder 4, thecontrol device 41 outputs detection data of theyarn monitoring devices 45 and unit identification information of the RF tags 63 to thetransmission unit 41x. Thetransmission unit 41x transmits the detection data and the unit identification information to the receivingunit 21x of theroving frame 2 and/or the receivingunit 31x of thespinning frame 3. - In the
roving frame 2, based on the detection data and/or the unit identification information received by the receivingunit 21x, thecontrol device 21 conducts the abnormality check described above to acquire abnormality information. For example, based on the detection data and the unit identification information, aroving unit 22 in which abnormality has occurred is identified, and information on thisroving unit 22 is acquired as the abnormality information. In some cases, based on the detection data, information on abnormality that is common to a plurality ofroving units 22 is acquired as the abnormality information. In thespinning frame 3, based on the detection data and/or the unit identification information received by the receivingunit 31x, thecontrol device 31 conducts the abnormality check described above to acquire abnormality information. For example, based on the detection data and the unit identification information, aspinning unit 32 in which abnormality has occurred is identified, and information on thisspinning unit 32 is acquired as the abnormality information. In some cases, based on the detection data, information on abnormality that is common to a plurality of spinningunits 32 is acquired as the abnormality information. - In this manner, previous step machines that are the
roving frame 2 and thespinning frame 3 can receive detection data and unit identification information (what is called raw data), not as results of the abnormality check. In the previous step machines, by acquiring abnormality information from the detection data, abnormality that has occurred can be grasped in a timely manner. In particular, in thespinning frame 3, aspinning unit 32 in which abnormality has occurred can be grasped in a timely manner. In thespinning frame 3, abnormality that is common to a plurality of spinningunits 32, such as an abnormal stop of the blower, can be grasped in a timely manner. - According to one aspect of the present invention, abnormality that has occurred in a previous step machine configured to perform a spinning process at a previous step for an automatic winder can be grasped in the previous step machine in a timely manner.
