The creel stand 6 of the yarn supplying section 2 has a plurality of yarn supplying package holding portions 20 (see FIG. 4) provided corresponding to the plurality of weights 9, respectively. Each of the plurality of yarn supply package holding portions 20 is configured to attach and detach two yarn supply packages Ps. That is, the yarn supply package holding portion 20 has two package mounting portions 21 (mounting portions of the present invention). For convenience of explanation, one of the two package mounting portions 21 is called a first mounting portion 22 and the other is called a second mounting portion 23 . Each of the first mounting portion 22 and the second mounting portion 23 is configured so that one yarn supplying package Ps can be attached and detached. The attachment and detachment of the yarn supply package Ps to and from the package attachment section 21 is performed by the creel robot 102 described above.

Each yarn supply package holding portion 20 of the yarn supply portion 2 is configured to be capable of continuously supplying the yarn Y as follows. For example, as shown in FIG. 4 , a first yarn supplying package PsA (a certain yarn supplying package of the present invention), which is one of the plurality of yarn supplying packages Ps, is attached to the first attaching portion 22 . A second yarn supplying package PsB (another yarn supplying package of the present invention) different from the first yarn supplying package PsA is attached to the second attaching portion 23 . The yarn Y is unwound from the first yarn supply package PsA. Also, the terminal end of the yarn Y contained in the first yarn supplying package PsA and the starting end of the yarn Y contained in the second yarn supplying package PsB are knotted (connected). Thus, a knot portion K (yarn connection portion) is formed between the two yarns Y. As shown in FIG. In such a case, it is possible to continuously supply the yarn Y from the second yarn supplying package PsB after the first yarn supplying package PsA is emptied. Specifically, immediately after the supply of the yarn Y from the first yarn supply package PsA is completed and the first yarn supply package PsA is emptied, the knot portion K is located on the downstream side in the yarn traveling direction (winding device 19 side). The yarn Y is unwound from the second yarn supplying package PsB by being pulled to. Thus, yarn supply package switching occurs in which the yarn supply package Ps that supplies the yarn Y is switched. Thereby, the yarn Y is supplied without interruption. After that, the empty yarn supply package Ps is replaced with a new yarn supply package Ps by the creel robot 102 .

A yarn detection sensor 24 (a detection portion of the present invention) is arranged downstream of the yarn supply package holding portion 20 in the yarn running direction.

The second detection section 26 is configured to detect whether or not the yarn Y is being supplied from the second mounting section 23 . The first detection unit 25 and the second detection unit 26 are, for example, optical sensors that optically detect the yarn Y, respectively. For more details of the thread detection sensor 24, see Japanese Patent No. 5873105, for example. Alternatively, the first detection unit 25 and the second detection unit 26 may be contact sensors, for example.

(process section)
The configuration of the processing unit 3 will be described with continued reference to FIGS. 3 and 4. FIG. Only a portion of the processing portion 3 corresponding to one weight 9 will be described below.

The first feed roller 11 is configured to unwind the yarn Y from the yarn supply package Ps attached to the yarn supply section 2 and feed it to the first heating device 13 . The first feed roller 11 is arranged on the upstream side of the twist stop guide 12 in the yarn traveling direction. The transport speed of the yarn Y by the first feed roller 11 is substantially equal to the unwinding speed V (see FIG. 4) at which the yarn Y is unwound from the yarn supply package Ps.

The twist stop guide 12 is configured so that the twist imparted to the yarn Y by the false twisting device 15 does not propagate upstream of the twist stop guide 12 in the yarn running direction. The twist stop guide 12 is arranged downstream of the first feed roller 11 in the yarn running direction and upstream of the first heating device 13 in the yarn running direction.

The first heating device 13 is configured to heat the yarn Y fed from the first feed roller 11 . The first heating device 13 is arranged downstream of the twist stop guide 12 in the yarn running direction and upstream of the cooling device 14 in the yarn running direction. In the present embodiment, the first heating device 13 is configured to heat one yarn Y for simplification of explanation, but the present invention is not limited to this. The first heating device 13 may be configured to be able to heat a plurality of yarns Y at the same time.

The cooling device 14 is configured to cool the yarn Y heated by the first heating device 13 . The cooling device 14 is arranged downstream of the first heating device 13 in the running direction of the yarn and upstream of the false twisting device 15 in the running direction of the yarn. In this embodiment, for the sake of simplicity of explanation, the cooling device 14 is configured to cool one yarn Y, but the configuration is not limited to this. The cooling device 14 may be configured to be able to cool a plurality of yarns Y at the same time.

The false twisting device 15 is configured to impart a twist to the yarn Y. As shown in FIG. The false twisting device 15 is, for example, a so-called disc friction type false twisting device, but is not limited thereto. The false twisting device 15 is arranged downstream of the cooling device 14 in the running direction of the yarn and upstream of the second feed roller 16 in the running direction of the yarn.

The second feed roller 16 is configured to feed the yarn Y processed by the false twisting device 15 to the second heating device 17 . The speed at which the yarn Y is conveyed by the second feed roller 16 is higher than the speed at which the yarn Y is conveyed by the first feed roller 11 . Thereby, the yarn Y is drawn between the first feed roller 11 and the second feed roller 16 .

The second heating device 17 is configured to heat the yarn Y fed from the second feed roller 16 . The second heating device 17 extends vertically. For simplification of explanation, the second heating device 17 is configured to heat one yarn Y, but is not limited to this. The second heating device 17 may be configured to be able to heat a plurality of yarns Y at the same time.

The third feed roller 18 is configured to feed the yarn Y heated by the second heating device 17 to the winding device 19 . The speed at which the yarn Y is conveyed by the third feed roller 18 is slower than the speed at which the yarn Y is conveyed by the second feed roller 16 . Yarn Y is slackened between second feed roller 16 and third feed roller 18 .

In the processing section 3 configured as described above, the yarn Y stretched between the first feed roller 11 and the second feed roller 16 is twisted by the false twisting device 15 . The twist formed by the false twisting device 15 propagates up to the twist stop guide 12, but does not propagate upstream of the twist stop guide 12 in the yarn traveling direction. The yarn Y, which is drawn and twisted, is heated by the first heating device 13 and thermally fixed, and then cooled by the cooling device 14 . Although the yarn Y is untwisted downstream from the false twisting device 15, each filament is maintained in a wavy false-twisted state due to the heat setting described above. Further, the yarn Y false twisted by the false twisting device 15 is loosened between the second feed roller 16 and the third feed roller 18, and is thermally fixed by the second heating device 17. It is guided downstream in the direction. Finally, the yarn Y fed from the third feed roller 18 is wound on the winding bobbin Bw by the winding device 19 . Thus, a winding package Pw is formed.

(Winding part)
The configuration of the winding unit 4 will be described with reference to FIGS. 3 and 4. FIG. The winding unit 4 has a plurality of winding devices 19 that wind the yarn Y onto the winding bobbin Bw, and a plurality of automatic doffers 10 (see FIG. 3) provided corresponding to the respective winding devices 19 . A plurality of winding devices 19 belong to each of a plurality of weights 9 (see FIG. 4). Each winding device 19 has, for example, a fulcrum guide 31, a traverse device 32, a cradle 33, and a winding roller . The fulcrum guide 31 is a guide that serves as a fulcrum when the yarn Y is traversed. The traverse device 32 is configured to be able to traverse the yarn Y, for example, by means of a traverse guide 35 attached to an endless belt reciprocatingly driven by a motor. The cradle 33 is configured to rotatably support the winding bobbin Bw (winding package Pw). The winding roller 34 is configured to rotate the winding package Pw and apply contact pressure to the surface of the winding package Pw. The winding roller 34 is rotationally driven by a motor (not shown) while in contact with the surface of the winding package Pw, for example. As a result, the winding package Pw is driven to rotate by the frictional force, and contact pressure is applied to the surface of the winding package Pw to adjust the shape of the winding package Pw. The winding package Pw may be directly driven to rotate by a motor (not shown) instead of rotating the winding roller 34 .

The auto doffer 10 is configured to remove the winding package Pw from the winding device 19 and mount an empty winding bobbin Bw to the winding device 19 . In other words, the automatic doffer 10 is configured such that the winding package Pw after completion of the formation and the empty winding bobbin Bw can be exchanged in the winding section 4 . The auto doffer 10 also has a cutter (not shown) capable of cutting the yarn Y near the winding package Pw. When the running yarn Y is cut by the cutter, the formation of the winding package Pw is completed. Here, even after the yarn is cut by the cutter, the yarn Y continues to be supplied to the winding device 19 side. After the formation of the winding package Pw, the automatic doffer 10 sucks and catches the traveling yarn Y supplied to the winding device 19 until the winding of the yarn Y onto the next winding bobbin Bw is started. It has a suction (not shown) that can be held. Until the yarn Y is wound on the winding bobbin Bw on which the yarn Y is wound next, the portion of the yarn Y that has been sucked by the suction is removed by suction. Further, the auto doffer 10 has a stocker 10a configured to temporarily store the winding package Pw removed from the corresponding winding device 19. As shown in FIG. The stocker 10a faces, for example, a space formed between the creel stand 6 and the winding table 8. As shown in FIG. The winding package Pw stored in the stocker 10a is collected by the winding package conveying device 103 described above. For more details such as the structure of the auto doffer 10, see, for example, Japanese Patent Application Laid-Open No. 6-212521.

In the winding unit 4 configured as described above, the yarn Y fed from the third feed roller 18 is wound on the winding bobbin Bw by each winding device 19 to form the winding package Pw ( winding process). When the yarn Y is cut by the cutter of the auto doffer 10, the process of winding the yarn Y onto the winding bobbin Bw is completed. Almost at the same time, the auto doffer 10 removes the winding package Pw from the cradle 33 . Immediately after that, the automatic doffer 10 mounts a new empty winding bobbin Bw on the cradle 33 . That is, immediately after a certain winding package Pw is formed, the winding package Pw (winding bobbin Bw) and a new winding bobbin Bw are exchanged by the auto doffer 10 (winding bobbin exchange work). Thereby, it is possible to start winding the yarn Y onto a new winding bobbin Bw. Note that “immediately after” means “after a very short period of time has passed compared to the time (winding time) required from the start of the winding process on a certain winding bobbin Bw to the end of the formation of the winding package Pw”. means. "Immediately after the winding package Pw is formed" can also be rephrased as "substantially simultaneously with the completion of the formation of the winding package Pw".

By the way, in order to appropriately manage the quality of the winding package Pw, it is desirable to know from which yarn supply package Ps the yarn Y was supplied when the winding package Pw was formed. In order to obtain such information, conventionally, means for associating the individual information of the yarn supplying package Ps with the individual information of the winding package Pw have been proposed. As a specific example of the conventional proposal, a tag (not shown) of individual information of each yarn supply package Ps, a tag (not shown) indicating the position of the first mounting portion 22, and a tag (not shown) indicating the position of the second mounting portion 23 (not shown) are read by a recognition device (not shown). Then, the individual information of the yarn supplying package Ps is associated with the first mounting portion 22 or the second mounting portion 23 based on the recognition result by the recognition device. Also, in prior art proposals, a detector (not shown) is provided to detect the passage of the nodal portion K. FIG. The machine control device 5 makes the following judgments, for example, in a state where it is known that the yarn is supplied from the first yarn supply package PsA. That is, if the passage of the knotted portion K is not detected by the detector during the period from the start of winding of the yarn Y onto the winding bobbin Bw to the end of the winding, only the yarn Y contained in the first yarn supply package PsA is It is determined that it has been supplied to the winding bobbin Bw. Further, when the passage of the knotted portion K is detected by the detector between the start of winding of the yarn Y onto the winding bobbin Bw and the end of winding, the yarn Y contained in the first yarn supplying package PsA and the second It is determined that both of the yarns Y contained in the yarn supply package PsB have been supplied to the winding bobbins Bw. In this way, information relating to the individual information of the winding package Pw and the individual information of the yarn supplying package Ps is obtained from the recognition result by the recognition device and the detection result by the detector. However, it is difficult to derive more detailed information only from the detection result.

Therefore, in this embodiment, the information management unit 110 acquires information described later in order to derive various useful information. As a specific example, the information management unit 110 acquires and manages various types of information about the events shown in the graphs of FIGS. 5(a) to 5(c). In the following description, unless otherwise specified, the description will be limited to the predetermined weight 9 .

(Specific example of event)
Before specifically explaining the information acquired by the information management unit 110, as a premise, events exemplified in the graphs of FIGS. and the time when each event occurred. The information management unit 110 acquires information about at least part of the events shown in the graphs of FIGS. 5(a) to 5(c) (details will be described later).

FIG. 5A shows the remaining amount of yarn Y (vertical axis) and the time (horizontal axis) contained in the yarn supplying package Ps (specifically, the yarn supplying packages Ps1 and Ps3) attached to the first attaching portion 22. FIG. is a graph showing the relationship between FIG. 5B shows the remaining amount of yarn Y (vertical axis) and the time (horizontal axis) contained in the yarn supplying package Ps (specifically, the yarn supplying packages Ps2 and Ps4) attached to the second attaching portion 23. is a graph showing the relationship between FIG. 5C shows the amount (vertical axis) of the yarn Y wound onto the winding bobbin Bw (specifically, the winding bobbins Bw1, Bw2, Bw3, Bw4, Bw5, and Bw6) and the time (horizontal axis). is a graph showing the relationship of 5A to 5C, the origin is the time t0 at which the yarn Y starts to be wound on the winding bobbin Bw1. Further, in the present embodiment, the yarn amount (initial amount) of each yarn supply package Ps when the yarn Y has not been unwound from each yarn supply package Ps is WF for convenience of explanation. Actually, in the preceding process of forming a plurality of yarn supplying packages Ps, the formation of the yarn supplying packages Ps may be terminated midway due to circumstances such as yarn breakage. Therefore, it should be noted that the initial amounts of the plurality of yarn supply packages Ps are not necessarily the same in practice.

First, at time t0, the yarn supplying package Ps1 is attached to the first attachment portion 22 . A yarn supplying package Ps2 is attached to the second attachment portion 23 . The remaining amount of the yarn Y contained in the yarn supply package Ps1 is W0 (less than the initial amount WF). The remaining amount of the yarn Y contained in the yarn supply package Ps2 is the initial amount WF. A knotted portion K is formed by knotting the terminal end of the yarn Y contained in the yarn supplying package Ps1 and the starting end of the yarn Y contained in the yarn supplying package Ps2.

At time t0 (time ts1), mounting of the winding bobbin Bw1 to the cradle 33 by the auto doffer 10 is completed, and the yarn starts to be wound on the winding bobbin Bw1. That is, the time ts1 is the winding start time when the yarn Y starts to be wound on the winding bobbin Bw1. At this time, the yarn Y is unwound from the yarn supply package Ps1. As time passes, the remaining amount of the yarn Y contained in the yarn supply package Ps1 decreases, and the winding amount of the yarn Y wound on the winding bobbin Bw1 increases. At time te1, the yarn Y is cut by the cutter of the auto doffer 10, and the winding process of the yarn Y onto the winding bobbin Bw1 is completed. That is, the time te1 is the winding end time at which the yarn Y has been completely wound onto the winding bobbin Bw1 (the formation of the winding package Pw1 has been completed). At this time, the remaining amount of the yarn supplying package Ps1 is W1. Only the yarn Y supplied from the yarn supply package Ps1 is wound on the winding bobbin Bw1. The cutting of the yarn Y by the cutter and the suction capture of the yarn Y by suction (that is, the start of removal of the yarn Y by suction) are performed almost simultaneously. Further, the winding bobbin Bw1 is removed from the cradle 33. FIG. Next, at time ts2 immediately after time te1, mounting of the winding bobbin Bw2 to the cradle 33 is completed, and winding of the yarn Y onto the winding bobbin Bw2 is started (replacement of the winding bobbin is completed). ). For example, the time when the machine control device 5 outputs a command signal for the winding bobbin replacement work to the auto doffer 10 (that is, the time when the winding bobbin replacement work is started) It can be regarded as bobbin replacement time (hereinafter simply referred to as replacement time). The replacement time is equal to the winding end time (time te1) of the winding bobbin Bw (in this case, the winding bobbin Bw1) attached to the cradle 33 before the winding bobbin replacement work. The replacement time is approximately equal to the winding start time (time ts2) of the winding bobbin Bw (in this case, the winding bobbin Bw2) attached to the cradle 33 after the winding bobbin replacement work.

At time ta1 after time ts2, the yarn supplying package Ps1 attached to the first attachment portion 22 is emptied. That is, the time ta1 is the unwinding end time when the yarn Y has been unwound from the yarn supplying package Ps1. A knotted portion formed by knotting the yarn Y contained in the yarn supplying package Ps1 and the yarn Y contained in the yarn supplying package Ps2 at time tb1 (=time ta1) at the same time that the yarn supplying package Ps1 is emptied. K is pulled toward the winding device 19 side. As a result, the yarn Y is first unwound from the yarn supply package Ps2 attached to the second attachment portion 23 . That is, the time tb1 is the unwinding start time at which the yarn Y is first unwound from the yarn supplying package Ps2 (the unwinding of the yarn Y begins). Thereafter, at time te2, the process of winding the yarn Y onto the winding bobbin Bw2 (formation of the winding package Pw2) ends. At this time, the remaining amount of the yarn supplying package Ps2 is W2. Both the yarn Y unwound from the yarn supplying package Ps1 and the yarn Y unwound from the yarn supplying package Ps2 are wound on the winding bobbin Bw2. A knot portion K is also included in the winding package Pw2. Thereafter, at time ts3, the process of winding the yarn Y onto the winding bobbin Bw3 is started. When the process of winding the yarn Y onto the winding bobbin Bw3 (formation of the winding package Pw3) is completed at time te3, the remaining amount of the yarn supplying package Ps2 is W3. Only the yarn Y supplied from the yarn supply package Ps3 is wound on the winding bobbin Bw3.

At time ta2 after time ta1 and before the yarn supplying package Ps2 is emptied, the creel robot 102 removes the yarn supplying package Ps1 from the first mounting unit 22 and transfers it to the first mounting unit 22. (Yarn supply package replacement work). At this time, the remaining amount of the yarn supplying package Ps3 is WF. Thereafter, the terminal end of the yarn Y contained in the yarn supplying package Ps2 and the starting end of the yarn Y contained in the yarn supplying package Ps3 are knotted at appropriate timing to form a knotted portion K. Here, for convenience of explanation, it is assumed that the knotting work (connection work) is performed by the operator immediately after the yarn feeding package replacement work by the creel robot 102 . The operator may work on the knot by hand. Alternatively, the operator may perform the knotting operation, for example, by manipulating a portable knotting device (not shown). Alternatively, the creel robot 102 may have an automatic knotting device (not shown) capable of performing knotting operations. Thus, the knot work may be performed by the creel robot 102 without relying on human labor.

A brief description of what happened after that is as follows. Events relating to the winding unit 4 are as follows. Yarn Y is wound on winding bobbin Bw4 from time ts4 to time te4 (winding package Pw4 is formed). From time ts5 to time te5, the yarn Y is wound on the winding bobbin Bw5 (the winding package Pw5 is formed). From time ts6 to time te6, the yarn Y is wound on the winding bobbin Bw6 (the winding package Pw6 is formed). Events related to the yarn supplying section 2 are as follows. At time tb2 (=time ta3) between time ts4 and time te4, yarn supply package Ps2 is emptied, and yarn Y begins to be unwound from yarn supply package Ps3. Thereafter, at time tb3, the yarn supplying package Ps2 is replaced with the yarn supplying package Ps4. At time ta4 (=time tb4) between time ts6 and time te6, the yarn supplying package Ps3 is emptied and the yarn Y begins to be unwound from the yarn supplying package Ps4.

(Summary of basic information acquired by the information management department)
Considering the above events, first, an outline of the basic information acquired by the information management unit 110 to perform various judgments and/or calculations will be described with reference to FIGS. . FIG. 6(a) is a table showing associations between yarn feeding package individual information and information on various times, which will be described later. FIG. 6(b) is a table showing the association between winding package individual information and various time information, which will be described later.

The information management unit 110 acquires, as basic information, yarn feeding package individual information, unwinding start time information, and unwinding end time information in association with each yarn feeding package Ps (see FIG. 6A). In addition, the information management unit 110 acquires, as basic information, individual winding package information and replacement time information in association with each winding package Pw (see FIG. 6B). The details of how to acquire these pieces of information will be described later. These pieces of information are at least information used for associating the yarn supplying package individual information, which is the individual information of the yarn supplying package Ps, with the winding package individual information, which is the individual information of the winding package Pw.

The yarn supplying package individual information is identification information given to each of the plurality of yarn supplying packages Ps. Each yarn supply package Ps is attached with, for example, an ID tag (not shown) indicating the individual information of the yarn supply package. The yarn supplying package individual information is used to identify the yarn supplying package Ps mounted on each package mounting portion 21 . The unraveling start time information is information on the unraveling start time described above. The unwinding start times are, for example, tb1, ta3, and tb4 described above. The unraveling end time information is information on the unraveling end time described above. The unwinding end times are, for example, the times ta1, tb2, and ta4 described above. The winding package individual information is identification information given to each of the plurality of winding packages Pw. The replacement time information is information on the replacement time described above. The replacement times are, for example, the times te1 to te6 described above. An exchange time can be treated as both a first exchange time and a second exchange time, as described below.

(Necessary information)
Next, information necessary for the information management unit 110 to actually acquire the yarn feeding package individual information, the unwinding start time information, the unwinding end time information, the winding package individual information, and the replacement time information will be described. More specifically, information on the yarn supply package Ps attached to and detached from the package mounting section 21, information on the winding package Pw, and information acquired by the machine control device 5 during the winding process will be described.

(Information about the yarn supply package conveyed by the creel robot)
The information management unit 110 manages the individual information of the yarn supply package Ps conveyed by the creel robot 102 and information associated therewith as follows. First, before or when the fully wound yarn supplying package Ps stored in the yarn supplying package stocker is loaded onto the creel robot 102 by the operator, the yarn supplying package individual information corresponding to the yarn supplying package Ps is It is input to the creel controller 102a by the operator. For example, the operator uses an ID reader (not shown) electrically connected to the creel control device 102a to read the ID tag attached to each yarn supply package Ps, thereby inputting the yarn supply package individual information. It's okay to be broken. Alternatively, based on the visible information displayed on each yarn supply package Ps, the operator may operate the creel control device 102a to input the yarn supply package individual information. Alternatively, the creel robot 102 may be provided with an ID reader (not shown), and the creel robot 102 may use the ID reader to read the ID tag.

When the creel robot 102 mounts the yarn supply package Ps on the package mounting unit 21, the information management unit 110 receives the individual information of the yarn supply package Ps from the creel control device 102a. Then, the information management section 110 associates the individual information of the yarn supplying package Ps with the individual information of the package mounting section 21 to which the yarn supplying package Ps is mounted (see FIG. 7A). The individual information of the package mounting portion 21 includes which of the plurality of weights 9 the package mounting portion 21 to which the yarn supplying package Ps is mounted belongs, and whether the package mounting portion 21 belongs to the first mounting portion 22 and the first mounting portion 22 . This is information about which one of the second mounting portions 23 it is. In this manner, the information management unit 110 manages the individual information of the yarn supply package Ps transported by the creel robot 102 in association with the operation of the creel robot 102 .

When a new yarn supplying package Ps is attached to the package attaching portion 21, the machine control device 5 provides the yarn supplying package attaching time information regarding the time when the yarn supplying package Ps is attached to the package attaching portion 21. get. The times when the yarn supply package is attached are, for example, the times ta2 and tb3 described above. The machine control device 5 stores the yarn feeding package individual information, the individual information of the package mounting section 21, and the yarn feeding package mounting time information in association with each yarn feeding package Ps (see FIG. 7A. 7(a), the time when the yarn feeding package is installed is simply referred to as the time when it is installed).

After a new yarn supplying package Ps is attached to one package attaching portion 21, the operator moves the starting end of the yarn Y contained in the yarn supplying package Ps to the yarn supplying package Ps attached to the other package attaching portion 21. to form a knot portion K. The operator then places the knot portion K in place. Furthermore, the operator inputs information to the machine control device 5 indicating that the knot portion K has been placed at a predetermined position. Based on the input information, the machine base control device 5 stores information indicating that the knot portion K is arranged at a predetermined position.

(Information about winding package)
Further, the information management unit 110 manages the individual information of the winding package Pw as follows. The machine control device 5 stores the time when the signal for replacing the winding bobbin Bw is output to the auto doffer 10 as the replacement time. As for the winding bobbin Bw newly attached to the cradle 33, this replacement time is approximately equal to the winding start time at which the yarn Y starts to be wound on the winding bobbin Bw. Such a replacement time is treated as a first replacement time for the winding bobbin Bw (winding package Pw). Further, when the process of winding the yarn Y onto the winding bobbin Bw is completed (when the formation of the winding package Pw is completed), the machine control device 5 stores the individual information (winding individual package information). Specifically, the machine control device 5 acquires, for example, information on the machine number (identification number of the false twisting machine 1) and information on the identification number of the weight 9 as the individual information of the winding package Pw. Further, the machine control device 5 stores the time when the signal for removing the winding package Pw from the winding device 19 is output to the auto doffer 10 as the second replacement time. The machine control device 5 stores information on the machine number and the identification number of the weight 9, information on the first replacement time (first replacement time information), and information on the second replacement time (second replacement time information). Store in association. Both the first replacement time information and the second replacement time information are included in the replacement time information. Further, the machine control device 5 may acquire a predetermined management number as the winding package individual information in association with these pieces of information, and assign it to each winding package Pw. For example, as shown in FIG. 6B, if the above-described "Pw1" to "Pw6" are management numbers (winding package individual information), the management numbers are associated with the first replacement time and the second replacement time. (Note that the machine number and the identification number of the weight 9 are omitted from the illustration). Further, the machine control device 5 prints this information on a label (not shown). The label can be attached to the winding bobbin Bw by the operator.

As another means for obtaining the winding package individual information, for example, an ID tag (not shown) may be previously attached to the empty winding bobbin Bw. Thus, the winding package individual information may be given in advance to the winding bobbin Bw before the winding process. Furthermore, the auto doffer 10 may have an ID reader (not shown). For example, when the winding bobbin Bw with the auto doffer 10 is attached to the winding device 19, or when the winding package Pw is removed from the winding device 19, the ID reader reads the ID attached to the winding bobbin Bw. By reading the tag, the individual information of the winding bobbin Bw may be transmitted to the machine control device 5 . Alternatively, instead of the auto-doffer 10, the operator may read the ID tag with an ID reader (not shown). Alternatively, instead of reading the ID tag with the ID reader, the operator may manually input the individual information of the winding bobbin Bw to the machine control device 5 .

The exchange time information includes both the first exchange time information and the second exchange time information, as described above. As a specific example, focus on the time te1. At time te1, a command signal for starting replacement work between the winding bobbin Bw1 (winding package Pw1) for which the yarn Y winding process has been completed and a new winding bobbin Bw2 (winding package Pw2) is output from the machine. This is the time output from the control device 5 . The time te1 is equal to the winding end time for the winding package Pw1 and approximately equal to the winding start time for the winding package Pw2. Therefore, as shown in FIG. 6B, the information management unit 110 treats the information of the time te1 as the first replacement time information, and associates the first replacement time information with the winding package individual information of the winding package Pw2. That is, the time te1 is treated as the first replacement time for the winding package Pw2. Further, the information management unit 110 handles the information of the time te1 as the second replacement time information, and associates the second replacement time information with the winding package individual information of the winding package Pw1. In this case, the time te1 is treated as the second replacement time for the winding package Pw1. Such first replacement time information and second replacement time information are similarly obtained for other winding packages Pw.

The first replacement time for a winding bobbin Bw (winding package Pw) can be used as the winding bobbin mounting time when the winding bobbin Bw is mounted on the cradle 33 . The second replacement time for a certain winding bobbin Bw (winding package Pw) can be used as the winding bobbin removal time when the winding bobbin Bw is removed from the cradle 33 . In other words, the first replacement time information can be used as winding start time information regarding the winding start time of the winding bobbin Bw. The second replacement time information can be used as winding end time information regarding the winding end time of the winding bobbin Bw. The information management unit 110 may directly handle the first replacement time information as the winding start time information, and may handle the second replacement time information as the winding end time information. Alternatively, the information management unit 110 may obtain more precise information on the winding start time and/or the winding end time by performing a predetermined calculation on the replacement time.

(Information acquired by machine control device during winding process)
Next, information acquired by the machine controller 5 during the process of winding the yarn Y onto the winding bobbin Bw will be described. These pieces of information are information for obtaining the yarn feeding package individual information, the unwinding start time information, and the unwinding end time information in association with each other by combining with the information shown in FIG. 7(a).

Based on the detection result of the yarn detection sensor 24, the machine control device 5 determines whether or not the yarn supply package switching in which the yarn supply package Ps supplying the yarn Y has been switched has occurred. For example, referring to FIGS. 5(a) and 5(b), the yarn supply package switching occurs when the yarn supply package Ps1 becomes empty and the yarn Y is first unwound from the yarn supply package Ps2. . The state of the yarn detection sensor 24 changes from the state in which one of the first detection unit 25 and the second detection unit 26 detects the yarn Y to the state in which the other of the first detection unit 25 and the second detection unit 26 detects the yarn Y. When the state is changed to the state where the yarn feeding package is changed, the machine control device 5 determines that the yarn feeding package is changed. When the machine controller 5 determines that the yarn supply package has been switched, it acquires and stores the following information shown in the table of FIG. 7(b). The machine control device 5 receives the individual information of the package mounting section 21 (either the first mounting section 22 or the second mounting section 23) that started supplying the yarn Y when the yarn supply package was switched, and the yarn supply It is stored in association with the time when the package switching occurred. Regarding the package mounting section 21 that has started supplying the yarn Y, the time at which the yarn supply package is switched is treated as the unwinding start time. Further, the machine control device 5 associates and stores the individual information of the package mounting section 21 that finished supplying the yarn Y when the yarn supply package was switched and the time when the yarn supply package was switched. Regarding the package mounting section 21 that has finished supplying the yarn Y, the time at which the yarn supply package is switched is treated as the unwinding end time.

(Method of Acquisition of Unleashment Start Time Information and Unleashment End Time Information)
Next, a method for acquiring the unwinding start time information and the unwinding end time information based on the information acquired by the machine control device 5 will be described with reference to FIGS. ) and FIG. FIG. 8 is a table showing associations between yarn feeding package individual information, package attachment units, and various times.

The machine control device 5 acquires the unwinding start time information and the unwinding end time information in the following procedure using the yarn feeding package mounting time information and the yarn feeding package switching information. As a specific example, when acquiring the unwinding start time and the unwinding end time of the yarn supplying package Ps3, the machine control device 5 controls the package mounting section to which the yarn supplying package Ps3 is mounted based on the yarn supplying package mounting time information. 21 individual information (first mounting portion 22) and information on the yarn feeding package mounting time (time ta2). Next, the machine control device 5 determines the earliest unwinding start time of the yarn supplying package Ps attached to the first attachment portion 22 (time ta3) which is later than the time ta2. ) and (b)) are acquired as the unwinding start time of the yarn supplying package Ps3. Further, the machine control device 5 acquires the information of the unwinding end time (time ta4) associated with the unwinding start time as the unwinding end time of the yarn supplying package Ps3. In this way, the individual information of the yarn supplying package Ps, the unwinding start time information, and the unwinding end time information are acquired in association with each other. In other words, by associating the yarn supplying package mounting time information of a certain yarn supplying package Ps with the information of the earliest yarn supply package switching after the yarn supplying package mounting time, it is possible to solve the yarn supplying package Ps. The unwinding start time information and the unwinding end time information are acquired (see FIG. 8). The above information is not limited to the yarn supplying package Ps3, and can be obtained for each yarn supplying package Ps.

As described above, the machine control device 5 acquires the unwinding start time information and the unwinding end time information. The machine control device 5 can acquire the unwinding start time information and the unwinding end time information at any timing. For example, the machine control device 5 may acquire the unwinding start time information and/or the unwinding end time information at the timing when the yarn feeding package is switched. Alternatively, when the operator performs some operation at an arbitrary timing, the machine control device 5 uses the previously acquired yarn package mounting time information and yarn package switching information to generate the unwinding start time information and the yarn feeding package switching information. / Or you may acquire unwinding end time information. Note that the management device 101 may acquire the unraveling start time information and/or the unraveling end time information.

(Association between winding package individual information and yarn feeding package individual information)
Next, a method for associating the individual winding package information and the individual yarn feeding package information will be described. Refer to the table shown in FIG. 9 for the specific association between the individual winding package information and the individual yarn feeding package information. In the following method, for example, the management apparatus 101 acquires association information, but the method is not limited to this. That is, the machine control device 5 may acquire the information.

As specific examples of association, first and second specific examples will be described below. As a first specific example, when the management device 101 acquires the individual information of the yarn supply package Ps that has supplied the yarn Y to the winding bobbin Bw3 (winding package Pw3), first, the management device 101 acquires the winding bobbin Bw3 (winding package Pw3). Pw3), the information of the first replacement time (time te2) and the second replacement time (time te3) is acquired. The first replacement time can be treated as the winding bobbin mounting time or the winding start time. The second replacement time can be treated as the winding bobbin removal time or the winding end time. Next, the management device 101 selects the yarn feeding package Ps (yarn feeding package Ps2, FIG. 6 ( b) Associate the individual information of reference) with the individual information of the winding package Pw3. In other words, the management device 101 identifies the yarn supply package Ps associated with the latest unwinding start time that precedes the winding start time among the individual information of the plurality of yarn supply packages Ps. Then, the management device 101 associates the individual information of the specified yarn supplying package Ps with the individual information of the winding package Pw associated with the winding start time. Further, the management device 101 determines whether or not the yarn feeding package has been switched between time te2 and time te3. In this example, there is no time (that is, unwinding start time) at which the yarn feeding package is switched between time te2 and time te3. Therefore, the management device 101 determines that the yarn feeding package switching did not occur between the time te2 and the time te3. Therefore, information is obtained that the yarn Y has been supplied to the winding package Pw3 only from the yarn supplying package Ps2 (see FIG. 9).

As a second specific example, when the management device 101 acquires the individual information of the yarn supply package Ps that has supplied the yarn Y to the winding bobbin Bw4 (winding package Pw4), first, the management device 101 acquires the winding bobbin Bw4 (winding package Pw4). Pw4) acquires information on the first replacement time (time te3) and information on the second replacement time (time te4). Next, the management device 101 selects the yarn feeding package Ps (yarn feeding package Ps2, FIG. 6 ( b) Associate the individual information of reference) with the individual information of the winding package Pw4. Furthermore, the management device 101 determines whether or not the yarn feeding package has been switched between time te3 and time te4. In this example, there is a time (that is, unwinding start time) at which the yarn feeding package is switched between time te3 and time te4 (time ta3). Therefore, the management device 101 determines that the yarn feeding package has been switched between time te3 and time te4. Based on this determination, the management device 101 associates the individual information of the yarn supplying package Ps (yarn supplying package Ps3; see FIG. 6B) associated with the time ta3 with the individual information of the winding package Pw4. In other words, the management device 101 selects the individual information of the yarn supplying package Ps associated with the unwinding start time between the first replacement time and the second replacement time among the individual information of the plurality of yarn supplying packages Ps. , with the individual information of the winding package Pw associated with the first replacement time. Therefore, the information that the yarn Y has been supplied from the yarn supplying package Ps2 and the yarn supplying package Ps3 to the winding package Pw3 is obtained (see FIG. 9).

(Determination of the presence or absence of nodules)
In addition, the management device 101 makes the following determinations depending on whether or not the yarn supply package switching described above has occurred. For example, the management device 101 determines that the yarn feeding package switching did not occur between the first replacement time (time te2) and the second replacement time (time te3) regarding the winding bobbin Bw3 (winding package Pw3). Then, it is determined that the winding package Pw3 does not include the knot portion K (see FIG. 9). Further, when the management device 101 determines that the yarn feeding package switching has occurred between the first replacement time (time te3) and the second replacement time (time te4) regarding the winding bobbin Bw4 (winding package Pw4). , that the winding package Pw4 includes the knot portion K (see FIG. 9).

Furthermore, the management device 101 estimates the mixed position of the knot portion K in the winding package Pw by performing the following calculation. As a simple example, the management device 101 determines the first replacement time (time te3) for the winding bobbin Bw4 (winding package Pw4) from the time te3 to the time (time ta3) when the yarn feeding package is switched. to the second exchange time (time te4). That is, the ratio of ta3-te3 to te4-te3 is calculated. Assuming that this value is, for example, N percent, it can be estimated that the knotted portion K was mixed into the winding package Pw4 when the yarn Y was wound on the winding bobbin Bw4 by N percent.

(chart output)
Also, the information management unit 110 outputs a chart described below. The information management unit 110 uses the yarn supplying package individual information, the unwinding start time information, the winding package individual information, and the replacement time information to determine the unwinding period for each yarn supplying package Ps and the winding period for each winding package Pw. Create chart data to show The unwinding period is a period from when the yarn Y starts to be unwound from the yarn supply package Ps to when it is completely unwound. The winding period is a period from when the yarn Y starts to be wound around the winding bobbin Bw until it finishes winding. The information management unit 110 causes the management output unit 101b (display) of the management device 101 to display graphs (charts) such as those shown in FIGS. 5A to 5C based on the created chart data ( output). The management device 101 corresponds to the output control section of the present invention. The management output section 101b corresponds to the output section of the present invention. The types of charts are not limited to those described above, and any chart that allows the operator to visually confirm the unwinding period for each yarn supplying package Ps and the winding period for each winding package Pw may be output. This allows the operator to easily associate the yarn feeding package individual information with the winding package individual information. The chart may show more detailed information in addition to the information shown in FIGS. 5(a) to 5(c). For example, the individual information of the yarn supplying package Ps associated with the winding package Pw may be displayed together with the individual information of the winding package Pw. Further, information indicating from which layer of the yarn Y contained in the yarn supplying package Ps the yarn Y was supplied to the winding package Pw may be displayed together with the yarn supplying package individual information. If the management output unit 101b has a printer, the information management unit 110 may cause the printer to print the chart. Alternatively, the information management section 110 may cause the machine base output section 5b of the machine base control device 5 to output (display) the chart. Alternatively, the output control unit that creates chart data and the output unit that outputs the chart may be provided separately from the information management unit 110 .

As described above, the information management unit 110 can know the unwinding start time of each yarn supply package Ps. Further, by acquiring the replacement time information, it is possible to know the winding start time and the winding end time for each winding package Pw. This makes it possible to obtain various information about the relationship between the winding bobbin Bw (winding package Pw) and the yarn supply package Ps. For example, it is possible to know from which layer of yarn Y of the yarn supply package Ps a certain winding package Pw is formed. Also, it can be determined whether or not the knot portion K is mixed in the winding package Pw. In this case, it is also possible to know at which position of the winding package Pw the knot portion K is mixed. A variety of useful information can thus be derived.

Further, by using the unwinding start time information and the replacement time information, it is possible to easily know that the knotted portion K is mixed in the winding package Pw.

In addition, by calculation using the first replacement time, the second replacement time, and the unwinding start time, the mixing position of the knot portion K in the winding package Pw can be easily known.

Further, the individual yarn feeding package information and the unwinding start time information are acquired in association with each other. As a result, it is possible to know from which yarn supply package Ps the yarn Y has been supplied to a certain winding bobbin Bw by considering the context of each time.

In addition, the operator can easily associate the winding package individual information with the yarn feeding package individual information simply by viewing the output chart.

Further, the individual information of the predetermined winding package Pw and the individual information of the yarn supplying package Ps which is supplying the yarn Y when the yarn starts to be wound on the predetermined winding package Pw are automatically obtained. can be associated.

Further, when the yarn Y is sequentially supplied from a plurality of yarn supplying packages Ps to a certain winding bobbin Bw, the individual information of all of the plurality of yarn supplying packages Ps is used as the individual information of the certain winding package Pw. can be associated automatically.

Further, when the yarn supplying package Ps is mounted on the package mounting unit 21 by the creel robot 102 , the yarn feeding package individual information can be automatically associated with the package mounting unit 21 .

In addition, the yarn detection sensor 24 can always determine from which of the plurality of package mounting portions 21 the yarn is supplied. Therefore, it is possible to automatically and accurately associate the yarn feeding package individual information with the unwinding start time information.

Next, a modification in which the above embodiment is modified will be described. However, components having the same configurations as those of the above-described embodiment are denoted by the same reference numerals, and descriptions thereof are omitted as appropriate.

For example, as shown in FIG. 10, the yarn feeding section 2a of the false twisting machine 1a may have a switching detection section 41 having a configuration different from the yarn detection sensor 24 in each spindle 9a. The switching detection unit 41 may have, for example, a supply sensor 42 and a nodule sensor 43 . The supply sensor 42 is configured to detect whether or not the yarn Y is being supplied from the first mounting portion 22 . The knot portion sensor 43 is configured to be able to detect the knot portion K that is placed stationary at a predetermined position. In such a configuration, when the knotted portion K moves from the predetermined position and the knotted portion K is no longer detected by the knotted portion sensor 43, it can be determined that the yarn supply package switching has occurred. Further, when the yarn supply package is switched, from which of the first mounting portion 22 and the second mounting portion 23 the yarn Y is supplied can be known based on the detection result of the supply sensor 42 . Thus, even when the detection result of the knot portion K is used, it is possible to know with certainty which of the first mounting portion 22 and the second mounting portion 23 the yarn Y is being supplied. Note that the nodule sensor 43 may be configured to detect the moving nodule K.

The operation of attaching and detaching the winding bobbin Bw may also be performed by the operator. Necessary information such as winding package individual information may be input to the machine control device 5, for example, by an operator.

(7) In the above-described embodiments, the information management unit 110 acquires the yarn feeding package individual information and the unwinding start time information in association with each yarn feeding package Ps, but the present invention is not limited to this. . The information management unit 110 does not necessarily need to acquire the yarn feeding package individual information and the unwinding start time information in association with each other. For example, the information management section 110 may acquire only the unwinding start time information for each yarn supplying package Ps without acquiring the individual yarn supplying package information. Even when such processing is performed, by using the unwinding start time information and the exchange time information, various useful information such as information on whether or not the knot portion K is included in the winding package Pw can be obtained. Obtainable.

(8) In the above-described embodiments, the machine control device 5 acquires the information of the time when the signal for causing the automatic doffer 10 to perform the winding bobbin replacement work is output as the replacement time information.

As described above, information relating to the individual information of the winding package and the individual information of the yarn feeding package is obtained from the recognition result by the recognition device and the detection result by the detector. However, it is difficult to derive more detailed information only from the recognition result and the detection result.

By the way, in order to appropriately manage the quality of the winding package Pw, it is desirable to know from which yarn supply package Ps the yarn Y was supplied when the winding package Pw was formed. In order to obtain such information, conventionally, means for associating the individual information of the yarn supplying package Ps with the individual information of the winding package Pw have been proposed. As a specific example of the conventional proposal, a tag (not shown) of individual information of each yarn supply package Ps, a tag (not shown) indicating the position of the first mounting portion 22, and a tag (not shown) indicating the position of the second mounting portion 23 (not shown) are read by a recognition device (not shown). Then, the individual information of the yarn supplying package Ps is associated with the first mounting portion 22 or the second mounting portion 23 based on the recognition result by the recognition device. Also, in prior art proposals, a detector (not shown) is provided to detect the passage of the nodal portion K. FIG. The machine control device 5 makes the following judgments, for example, in a state where it is known that the yarn is supplied from the first yarn supply package PsA. That is, if the passage of the knotted portion K is not detected by the detector during the period from the start of winding of the yarn Y onto the winding bobbin Bw to the end of the winding, only the yarn Y contained in the first yarn supply package PsA is It is determined that it has been supplied to the winding bobbin Bw. Further, when the passage of the knotted portion K is detected by the detector between the start of winding of the yarn Y onto the winding bobbin Bw and the end of winding, the yarn Y contained in the first yarn supplying package PsA and the second It is determined that both of the yarns Y contained in the yarn supply package PsB have been supplied to the winding bobbins Bw. In this way, information relating to the individual information of the winding package Pw and the individual information of the yarn supplying package Ps is obtained from the recognition result by the recognition device and the detection result by the detector. However, it is difficult to derive more detailed information only from the recognition result and the detection result.

At time ta1 after time ts2, the yarn supplying package Ps1 attached to the first attachment portion 22 is emptied. That is, the time ta1 is the unwinding end time when the yarn Y has been unwound from the yarn supplying package Ps1. A knotted portion formed by knotting the yarn Y contained in the yarn supplying package Ps1 and the yarn Y contained in the yarn supplying package Ps2 at time tb1 (=time ta1) at the same time that the yarn supplying package Ps1 is emptied. K is pulled toward the winding device 19 side. As a result, the yarn Y is first unwound from the yarn supply package Ps2 attached to the second attachment portion 23 . That is, the time tb1 is the unwinding start time at which the yarn Y is first unwound from the yarn supplying package Ps2 (the unwinding of the yarn Y begins). Thereafter, at time te2, the process of winding the yarn Y onto the winding bobbin Bw2 (formation of the winding package Pw2) ends. At this time, the remaining amount of the yarn supplying package Ps2 is W2. Both the yarn Y unwound from the yarn supplying package Ps1 and the yarn Y unwound from the yarn supplying package Ps2 are wound on the winding bobbin Bw2. A knot portion K is also included in the winding package Pw2. Thereafter, at time ts3, the process of winding the yarn Y onto the winding bobbin Bw3 is started. When the process of winding the yarn Y onto the winding bobbin Bw3 (formation of the winding package Pw3) is completed at time te3, the remaining amount of the yarn supplying package Ps2 is W3. Only the yarn Y supplied from the yarn supply package Ps2 is wound on the winding bobbin Bw3 .

As specific examples of association, first and second specific examples will be described below. As a first specific example, when the management device 101 acquires the individual information of the yarn supply package Ps that has supplied the yarn Y to the winding bobbin Bw3 (winding package Pw3), first, the management device 101 acquires the winding bobbin Bw3 (winding package Pw3). Pw3), the information of the first replacement time (time te2) and the second replacement time (time te3) is acquired. The first replacement time can be treated as the winding bobbin mounting time or the winding start time. The second replacement time can be treated as the winding bobbin removal time or the winding end time. Next, the management device 101 selects the yarn feeding package Ps (yarn feeding package Ps2, FIG. 6 ( b) Associate the individual information of reference) with the individual information of the winding package Pw3. In other words, the management device 101 identifies individual information of the yarn supplying package Ps associated with the most recent unwinding start time before the winding start time among the individual information of the plurality of yarn supplying packages Ps. . Then, the management device 101 associates the individual information of the specified yarn supplying package Ps with the individual information of the winding package Pw associated with the winding start time. Further, the management device 101 determines whether or not the yarn feeding package has been switched between time te2 and time te3. In this example, there is no time (that is, unwinding start time) at which the yarn feeding package is switched between time te2 and time te3. Therefore, the management device 101 determines that the yarn feeding package switching did not occur between the time te2 and the time te3. Therefore, information is obtained that the yarn Y has been supplied to the winding package Pw3 only from the yarn supplying package Ps2 (see FIG. 9).
