Abstract
The invention relates to a silk thread processing device. In a yarn processing device capable of supplying a yarn without interruption, various useful information can be derived. The wire processing device (100) is provided with an information management unit (110) configured to be able to manage information. The information management unit (110) can acquire, for each yarn supply package (Ps), unwinding start time information relating to the unwinding start time at which the yarn (Y) starts to be unwound from the yarn supply package (Ps) in the yarn supply unit (2). The information management unit (110) can acquire, in association with each winding package (Pw), winding package individual information of the winding package (Pw) formed by winding the yarn (Y) on the winding tube (Bw) attached to the winding unit (4), and replacement time information relating to replacement time at which the winding tube (Bw) is replaced in the winding unit (4).
Description
Technical Field
The invention relates to a silk thread processing device.
Background
The machine control unit that controls the yarn processing device is configured to determine from which yarn feeding package the yarn is supplied to a certain winding package (that is, to associate the individual information of the winding package with the individual information of the yarn feeding package). Specifically, a tag of individual information of each yarn supply package and a position identification tag indicating a position of a package mounting portion (a 1 st mounting portion and a2 nd mounting portion) for mounting the yarn supply package are read by the identification device. Then, the individual information of the yarn supply package is associated with the package mounting section based on the recognition result of the recognition device. Further, the yarn processing apparatus is provided with a detector that detects the knotted portion. The machine control unit performs the following determination in a state where it is known from which yarn supply package the yarn is being supplied (for example, in a state where it is known that the yarn is being supplied from the 1 st yarn supply package). That is, when the detector does not detect the knotted portion during the period from the start to the end of winding of the yarn on the winding bobbin, it is determined that only the yarn contained in the 1 st yarn supply package is supplied to the winding bobbin. When the detector detects the knotted portion during a period from the start to the end of winding of the yarn on the winding bobbin, it is determined that both the yarn contained in the 1 st yarn supply package and the yarn contained in the 2 nd yarn supply package are supplied to the winding bobbin.
Patent document 1: international publication No. 2020/127489
As described above, the information on the association between the individual information on the winding package and the individual information on the yarn feeding package can be obtained based on the recognition result of the recognition device and the detection result of the detector. However, it is difficult to derive more detailed information only from the recognition result and the detection result.
Disclosure of Invention
The purpose of the present invention is to derive various useful information in a yarn processing device capable of supplying a yarn without interruption.
The wire processing apparatus of claim 1 includes: a yarn processing machine including a yarn feeding unit configured to be capable of supplying a yarn, a processing unit configured to be capable of processing the yarn supplied from the yarn feeding unit, and a winding unit configured to wind the yarn processed by the processing unit on a winding bobbin to form a winding package; and an information management section configured to manage information relating to the yarn processing machine, wherein the yarn supply section includes a plurality of mounting sections to which a plurality of yarn supply packages are detachably mounted, and the yarn supply section is configured to supply the yarn without interruption when a terminal end portion of the yarn contained in the yarn supply package mounted on one of the mounting sections and a starting end portion of the yarn contained in the yarn supply package mounted on a mounting section other than the one of the mounting sections are connected, the winding section is configured to start winding the yarn onto a new winding bobbin replaced with a certain winding bobbin immediately after the yarn is wound onto the certain winding bobbin, and the information management section is configured to acquire, for each yarn supply package, unwinding start time information relating to a unwinding start time at which the yarn unwinding from the yarn supply package starts, and the winding package individual information of the winding package formed by winding the yarn around the winding tube attached to the winding unit and the replacement time information related to the replacement time at which the winding tube is replaced in the winding unit can be obtained in association with each winding package.
In the present invention, the unwinding start time of each yarn supply package is acquired. In the present invention, the time of replacing each take-up bobbin is acquired. Thus, the timing at which a certain winding bobbin is attached to the winding unit can be handled as the winding start timing at which the winding of the yarn onto the certain winding bobbin is started. The timing at which the certain winding bobbin is replaced with the next winding bobbin (that is, the timing at which the certain winding bobbin is removed from the winding section) can be treated as the winding end timing at which the winding of the yarn on the certain bobbin and the formation of the wound package are ended. In this way, the winding start time and the winding end time can be known for each winding bobbin (winding package).
Thus, in the present invention, various information can be obtained about the relationship between the winding bobbin (winding package) and the yarn feeding package. For example, by performing calculation using information at each time, it is possible to know which layer of the yarn from the yarn supplying package a certain winding package is formed from. Further, for example, when there is unwinding start time between the winding start time and the winding end time of a certain winding package, it can be determined that a yarn connecting portion formed by connecting the terminal end portion and the starting end portion of the yarn is mixed in the certain winding package. In this case, it is possible to know the position of the yarn splicing portion mixed in the certain winding package. In this way, various useful information can be derived.
The yarn processing apparatus according to claim 2 is characterized in that, in the 1 st aspect, the information management unit determines that a yarn connecting portion, which is formed by connecting the starting end portion and the terminal end portion, is mixed in a predetermined winding package formed by winding the yarn around a predetermined winding bobbin, when the unwinding start time is present between a1 st replacement time at which the predetermined winding bobbin is attached to the winding unit and a2 nd replacement time at which the predetermined winding bobbin is detached from the winding unit, based on the unwinding start time information and the replacement time information.
In the present invention, the unwinding start time information and the replacement time information can be used to easily know that the yarn connecting portion is mixed in the winding package.
The yarn processing machine according to claim 3 is characterized in that, in the 2 nd aspect of the invention, the information management unit estimates the mixing position of the yarn joining section in the predetermined winding package based on the 1 st replacement time, the 2 nd replacement time, and the unwinding start time.
In the present invention, the position of the yarn joining portion mixed in the winding package can be easily known by using the calculations of the 1 st replacement time, the 2 nd replacement time, and the unwinding start time.
The yarn processing apparatus according to claim 4 is characterized in that, in any one of the inventions 1 to 3, the information management unit is configured to be able to acquire the individual yarn supply package information of the yarn supply package mounted by the yarn supply unit and the unwinding start time information in association with each other for each yarn supply package.
In the present invention, the individual information of the yarn supply package and the unwinding start time information are acquired in association with each other. Thus, by considering the front-rear relationship at each time, it is known from which yarn supply package the yarn is supplied to a certain winding bobbin.
The yarn processing machine according to claim 5 is characterized in that, in the 4 th aspect, the yarn processing machine includes an output unit configured to be capable of outputting information, and an output control unit configured to control the output unit, wherein the output control unit creates graph data indicating an unwinding period from the start of unwinding to the end of unwinding of the yarn for each yarn supply package and a winding period from the start of winding the yarn to the end of winding for each winding package, using the yarn supply package individual information, the unwinding start time information, the winding package individual information, and the replacement time information, and causes the output unit to output a graph based on the graph data.
In the present invention, the operator can easily associate the winding package individual information with the yarn feeding package individual information by simply observing the outputted chart.
The yarn processing apparatus according to claim 6 is characterized in that, in the 4 th or 5 th aspect, the information management unit specifies a supply package from which the yarn is newly unwound before the 1 st replacement time at which the predetermined winding bobbin is mounted on the winding unit, based on the unwinding start time information and the replacement time information, and associates the supply package individual information of the supply package with the winding package individual information of the predetermined winding package formed by winding the yarn on the predetermined winding bobbin.
In the present invention, at least the individual information of the predetermined winding package and the individual information of the yarn supply package that supplies the yarn when the formation of the predetermined winding package is started can be automatically associated with each other.
The yarn processing machine according to claim 7 is characterized in that, in the 6 th aspect of the invention, the information management unit associates the individual yarn supply package information of the yarn supply package at the unwinding start time with the individual winding package information of the predetermined winding package, when the unwinding start time is present between the 1 st replacement time and the 2 nd replacement time at which the predetermined winding package is removed from the winding unit.
In the present invention, when the yarn is supplied sequentially from the plurality of yarn feeding packages at the time of forming a certain winding package, the individual information of all of the plurality of yarn feeding packages can be automatically associated with the individual information of the certain winding package.

In the present invention, when the yarn supply package is mounted on the mounting portion by the yarn supply package conveying device, the individual information of the yarn supply package can be automatically associated with the mounting portion.
The yarn processing apparatus according to claim 9 is characterized in that, in any one of the inventions 4 to 8, the yarn processing apparatus includes a detection unit capable of detecting from which mounting unit of the plurality of mounting units the yarn is being unwound, and the information management unit associates the individual yarn supply package information with the unwinding start time information based on a detection result of the detection unit.
In the present invention, the individual yarn supply package information and the unwinding start time information can be easily associated with each other by using the detection result of the detection unit.
Further, for example, when the operation of the yarn processing machine is started, the yarn can be supplied from any one of the plurality of yarn feeding packages attached to the yarn feeding unit. In such a case, in a configuration in which the detection unit is not provided as described above, it is difficult to automatically determine from which yarn supply package the yarn supply has been started only by the electronic mechanism. In this regard, in the present invention, the detection unit can constantly determine from which of the plurality of attachment units the yarn is being supplied. Accordingly, the association between the individual yarn supply package information and the unwinding start time information can be automatically and accurately achieved.

The false twist texturing machine 1 is arranged such that the span is symmetrical with respect to the center line C of the main body 7 in the machine width direction as a symmetry axis and the paper surface is symmetrical (the main body 7 is common in the left and right spans). In addition, a plurality of spans are arranged along the length direction of the machine body.
The group of components through which 1 yarn Y is supplied from the yarn supplying unit 2 and passes to the winding unit 4 is referred to as a "spindle". In other words, the false twist texturing machine 1 has the same number of spindles 9 as the number of winding packages Pw that can be formed simultaneously (see fig. 4). In general, the plurality of spindles 9 are arranged in a row along the longitudinal direction of the machine body. In inclusive relationship, the false twist texturing machine 1 has a plurality of spans, each span having a plurality of spindles 9.
(filament supply part)
The configuration of the yarn feeding section 2 will be described with reference to fig. 3 and 4. The creel 6 of the yarn feeding section 2 includes a plurality of yarn feeding package holding sections 20 (see fig. 4) provided corresponding to the plurality of spindles 9, respectively. The yarn feeding package holding sections 20 are each configured to be able to attach and detach two yarn feeding packages Ps. That is, the yarn supply package holding section 20 has two package mounting sections 21 (mounting sections according to the present invention). For convenience of description, one of the two package mounting units 21 is referred to as a1 st mounting unit 22, and the other is referred to as a2 nd mounting unit 23. The 1 st mounting portion 22 and the 2 nd mounting portion 23 are each configured to be able to attach and detach one yarn feeding package Ps. The yarn feeding package Ps is mounted and dismounted on and from the package mounting section 21 by the bobbin robot 102.
Each yarn feeding package holding section 20 of the yarn feeding section 2 is configured to be able to supply the yarn Y without interruption as follows. For example, as shown in fig. 4, the 1 st yarn supplying package PsA (a yarn supplying package according to the present invention) which is one of the plurality of yarn supplying packages Ps is mounted on the 1 st mounting portion 22. Further, a2 nd yarn feeding package PsB (another yarn feeding package according to the present invention) different from the 1 st yarn feeding package PsA is mounted to the 2 nd mounting unit 23. The yarn Y is unwound from the 1 st yarn supply package PsA. Further, the terminal end portion of the yarn Y contained in the 1 st yarn supply package PsA is knotted (connected) to the starting end portion of the yarn Y contained in the 2 nd yarn supply package PsB. Thereby, a knotted portion K (a yarn connecting portion) is formed between the two yarns Y. In this case, the yarn Y can be supplied from the 2 nd yarn supply package PsB without interruption after the 1 st yarn supply package PsA becomes empty. Specifically, immediately after the supply of the yarn Y from the 1 st yarn supply package PsA is completed and the 1 st yarn supply package PsA becomes empty, the knotted portion K is pulled toward the downstream side in the yarn running direction (the winding device 19 side), whereby the yarn Y is unwound from the 2 nd yarn supply package PsB. Thus, the yarn supply package switching is performed in which the yarn supply package Ps for supplying the yarn Y is switched. Thereby, the yarn Y is supplied without interruption. Then, the empty yarn supply package Ps is replaced with a new yarn supply package Ps by the bobbin robot 102.
A yarn detection sensor 24 (a detection section of the present invention) is disposed on the downstream side of the yarn feeding package holding section 20 in the yarn running direction. The thread detection sensor 24 is configured to be able to detect from which of the 1 st and 2 nd mounting portions 22 and 23 the thread Y is being supplied. As shown in fig. 4, the thread detecting sensor 24 includes a1 st detecting unit 25 and a2 nd detecting unit 26. The 1 st detection unit 25 is configured to be able to detect whether or not the yarn Y is being supplied from the 1 st mounting unit 22. The 2 nd detection unit 26 is configured to be able to detect whether or not the yarn Y is being supplied from the 2 nd mounting unit 23. The 1 st detection unit 25 and the 2 nd detection unit 26 are, for example, optical sensors that optically detect the yarn Y. For more details of the thread detecting sensor 24, for example, refer to japanese patent No. 5873105. Alternatively, the 1 st detection unit 25 and the 2 nd detection unit 26 may be contact sensors, for example.
(processing section)
The structure of the processing section 3 will be described with reference to fig. 3 and 4. In the following, only a portion corresponding to one spindle 9 in the processing section 3 will be described.
The 1 st 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 the yarn Y to the 1 st heating device 13. The 1 st feed roller 11 is disposed on the upstream side of the twist stop yarn guide 12 in the yarn running direction. The feed speed of the first feed roller 11 to the yarn Y1 is substantially equal to the unwinding speed V (see fig. 4) of the yarn Y from the yarn supply package Ps.
The twist stopping yarn guide 12 is configured to prevent the twist applied to the yarn Y by the false twisting device 15 from propagating to the upstream side of the yarn advancing direction of the twist stopping yarn guide 12. The yarn guide 12 is disposed downstream of the 1 st feed roller 11 in the yarn running direction and upstream of the 1 st heating device 13 in the yarn running direction.
The 1 st heating device 13 is configured to heat the yarn Y fed from the 1 st feed roller 11. The 1 st heating device 13 is disposed on the downstream side in the yarn running direction of the twist stop yarn guide 12 and on the upstream side in the yarn running direction of the cooling device 14. In the present embodiment, the 1 st heating device 13 is configured to heat the 1 yarn Y for the sake of simplifying the description, but is not limited to this. The 1 st heating device 13 may be configured to simultaneously heat a plurality of yarns Y.
The cooling device 14 is configured to cool the yarn Y heated by the 1 st heating device 13. The cooling device 14 is disposed downstream of the 1 st heating device 13 in the yarn running direction and upstream of the false twisting device 15 in the yarn running direction. In the present embodiment, the cooling device 14 is configured to cool 1 wire Y for the sake of simplifying the description, but is not limited to this. The cooling device 14 may be configured to simultaneously cool the plurality of yarns Y.
The false twisting device 15 is configured to twist the yarn Y. The false twisting device 15 is not limited to a friction disk type false twisting device, for example. The false twisting device 15 is disposed on the downstream side in the yarn running direction of the cooling device 14 and on the upstream side in the yarn running direction of the 2 nd feed roller 16.
The 2 nd feed roller 16 is configured to convey the yarn Y treated by the false twisting device 15 to the 2 nd heating device 17. The speed of the yarn Y fed by the 2 nd feed roller 16 is faster than the speed of the yarn Y fed by the 1 st feed roller 11. Thereby, the yarn Y is stretched between the 1 st feed roll 11 and the 2 nd feed roll 16.
The 2 nd heating device 17 is configured to heat the yarn Y fed from the 2 nd yarn feeding roll 16. The 2 nd heating device 17 extends in the vertical direction. For the sake of simplifying the explanation, the 2 nd heating device 17 is configured to heat the 1 yarn Y, but is not limited thereto. The 2 nd heating device 17 may be configured to simultaneously heat a plurality of yarns Y.
The 3 rd feed roller 18 is configured to feed the yarn Y heated by the 2 nd heating device 17 to the winding device 19. The feed speed of the yarn Y by the 3 rd feed roller 18 is slower than the feed speed of the yarn Y by the 2 nd feed roller 16. The filament Y is relaxed between the 2 nd 16 and 3 rd 18 feed rolls.
In the working section 3 configured as described above, the yarn Y stretched between the 1 st feed roller 11 and the 2 nd feed roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the yarn stop guide 12 without propagating to the upstream side in the yarn advancing direction of the yarn stop guide 12. The yarn Y, which is twisted while being stretched, is heated by the 1 st heating device 13 and heat-set, and then cooled by the cooling device 14. The yarn Y is untwisted downstream of the false twisting device 15, but the state in which the respective filaments are false-twisted into waves by the heat setting is maintained. The yarn Y false-twisted by the false twisting device 15 is loosened between the 2 nd yarn feeding roller 16 and the 3 rd yarn feeding roller 18, heat-set by the 2 nd heating device 17, and then guided to the downstream side in the running direction of the yarn. Finally, the yarn Y fed from the 3 rd feed roller 18 is wound around the winding bobbin Bw by the winding device 19. Thereby, the winding package Pw is formed.
(winding part)
The structure of the winding unit 4 will be described with reference to fig. 3 and 4. The winding unit 4 includes a plurality of winding devices 19 that wind the yarn Y around the winding bobbin Bw, and a plurality of automatic doffers 10 (see fig. 3) provided corresponding to the respective winding devices 19. The plurality of winding devices 19 belong to the plurality of spindles 9 one by one (see fig. 4). Each winding device 19 includes, for example, a fulcrum guide 31, a traverse device 32, a cradle 33, and a winding roller 34. The fulcrum guide 31 is a guide that serves as a fulcrum when the yarn Y traverses. The traverse device 32 is configured to traverse the yarn Y by a traverse guide 35 attached to an endless belt driven to reciprocate by a motor, for example. 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 a contact pressure to a surface of the winding package Pw. The winding roller 34 is rotationally driven by a motor, not shown, in a state of being in contact with the surface of the winding package Pw, for example. Thus, the winding package Pw is driven to rotate by the friction force, and the contact pressure is applied to the surface of the winding package Pw to adjust the shape of the winding package Pw. Instead of the winding roller 34 being driven to rotate, the winding package Pw may be directly driven to rotate by a motor not shown.
The automatic doffer 10 is configured to remove the winding package Pw from the winding device 19 and mount the empty winding bobbin Bw to the winding device 19. In other words, the automatic doffer 10 is configured to be able to replace the winding package Pw formed last with an empty winding bobbin Bw in the winding unit 4. The automatic doffer 10 includes a cutter, not shown, capable of cutting the yarn Y near the winding package Pw. The running yarn Y is cut by the cutter, and the formation of the winding package Pw is completed. Here, even after the cutter has cut the yarn, the yarn Y is continuously supplied to the winding device 19. The automatic doffer 10 includes a suction unit, not shown, which can suck and hold the running yarn Y supplied to the winding device 19 during a period from when the formation of the winding package Pw is completed to before the start of winding the yarn Y onto the next winding bobbin Bw. The portion of the yarn Y sucked by the suction unit is sucked and removed until the yarn Y is caught by the winding bobbin Bw to which the yarn Y is wound next. The automatic doffer 10 includes a storage unit 10a, and the storage unit 10a is configured to temporarily store the winding package Pw taken out from the corresponding winding device 19. The storage 10a faces, for example, a space formed between the creel 6 and the winding table 8. The winding package Pw stored in the storage section 10a is collected by the winding package transfer device 103. For further details of the structure of the automatic doffer 10, for example, refer to japanese patent application laid-open No. 6-212521.
In the winding unit 4 configured as described above, the yarn Y fed from the 3 rd feed roller 18 is wound around the winding bobbin Bw by each winding device 19 to form a winding package Pw (winding process). The yarn Y is cut by the cutter of the automatic doffer 10, and the winding process of the yarn Y on the winding bobbin Bw is completed. At substantially the same time, the winding package Pw is taken out from the cradle 33 by the automatic doffer 10. Immediately after this, a new empty winding bobbin Bw is mounted on the cradle 33 by the automatic doffer 10. That is, immediately after a certain winding package Pw is formed, the automatic doffer 10 replaces the winding package Pw (the winding bobbin Bw) with a new winding bobbin Bw (a winding bobbin replacement operation). This enables the yarn Y to start winding on the new winding bobbin Bw. "immediately after …" means "after an extremely short time has elapsed from the start of the winding process on a certain winding bobbin Bw to the end of the formation of the winding package Pw (winding time)". The "immediately after the formation of the winding package Pw" can be, in other words, "substantially at the same time as the formation of the winding package Pw is completed".
However, in order to appropriately manage the quality of the winding package Pw, it is preferable to know from which yarn supply package Ps the yarn Y is supplied when the winding package Pw is formed. In order to obtain such information, a mechanism for associating individual information of the yarn supplying package Ps with individual information of the winding package Pw has been proposed. As a specific example of the conventional proposal, a tag (not shown) for reading individual information of each yarn supplying package Ps, a tag (not shown) for indicating the position of the 1 st mounting portion 22, and a tag (not shown) for indicating the position of the 2 nd mounting portion 23 are read by a recognition device (not shown). Then, based on the recognition result of the recognition device, the individual information of the yarn supplying package Ps is associated with the 1 st mounting part 22 or the 2 nd mounting part 23. In addition, in the conventional proposal, a detector (not shown) for detecting the passage of the knotted portion K is provided. The machine body control device 5 performs the following determination, for example, in a state where it is known that the yarn is being supplied from the 1 st yarn supply package PsA. That is, when the detector does not detect the passage of the knotted portion K during the period from the start of winding the yarn Y on the winding bobbin Bw to the end of winding, it is determined that only the yarn Y included in the 1 st yarn supplying package PsA is supplied to the winding bobbin Bw. When the passage of the knotted portion K is detected by the detector during the period from the start of winding the yarn Y on the winding bobbin Bw to the end of winding, it is determined that both the yarn Y contained in the 1 st yarn supply package PsA and the yarn Y contained in the 2 nd yarn supply package PsB are supplied to the winding bobbin Bw. In this way, the information of the association between the individual information of the winding package Pw and the individual information of the yarn supply package Ps is obtained based on the identification result of the identification device and the detection result of the detector. However, it is difficult to derive more detailed information only from the recognition result and the detection result.
Therefore, in the present embodiment, the information management unit 110 acquires information described below in order to be able to derive various useful information. The information management unit 110 acquires and manages various kinds of information related to the phenomena shown in the graphs of (a) to (c) of fig. 5 as a specific example. In the following description, unless otherwise specified, the spindle 9 is limited to the above-described spindle.
(specific example of phenomenon)
Before specifically describing the information acquired by the information management unit 110, in order to help understanding the following description, the phenomena illustrated in the graphs in fig. 5 (a) to (c) and the timings at which the respective phenomena occur will be described as a premise. The information management unit 110 acquires information related to at least a part of the phenomena shown in the graphs of fig. 5 (a) to (c) (details will be described later).
Fig. 5 (a) is a graph showing a relationship between the remaining amount of the yarn Y (vertical axis) and the time (horizontal axis) in the yarn supplying packages Ps (specifically, the yarn supplying packages Ps1, Ps3) mounted in the 1 st mounting part 22. Fig. 5 (b) is a graph showing a relationship between the remaining amount of the yarn Y (vertical axis) and the time (horizontal axis) in the yarn supplying packages Ps (specifically, the yarn supplying packages Ps2, Ps4) mounted in the 2 nd mounting unit 23. Fig. 5 (c) is a graph showing the relationship between the amount of yarn Y wound (vertical axis) and the time (horizontal axis) on the winding bobbins Bw (specifically, the winding bobbins Bw1, Bw2, Bw3, Bw4, Bw5, and Bw 6). In any of the graphs (a) to (c) of fig. 5, the point t0 at which the winding of the yarn Y onto the winding bobbin Bw1 is started is the origin. In the present embodiment, for convenience of explanation, the yarn amount (initial amount) of each yarn supplying package Ps is WF in a state where the yarn Y is not unwound from each yarn supplying package Ps once. In addition, in practice, in a pre-process for forming a plurality of yarn feed packages Ps, the formation of the yarn feed packages Ps may be terminated halfway due to yarn breakage or the like. Therefore, in practice, it is necessary to note that the initial amounts of the plurality of yarn feeding packages Ps are not always the same.
First, at time t0, the yarn supplying package Ps1 is mounted in the 1 st mounting unit 22. The yarn feeding package Ps2 is mounted on the 2 nd mounting portion 23. The remaining amount of the yarn Y contained in the yarn supply package Ps1 is W0 (smaller than the initial amount WF). The remaining amount of the yarn Y contained in the yarn supplying package Ps2 is the initial amount WF. Further, the terminal end portion of the yarn Y contained in the yarn supplying package Ps1 and the starting end portion of the yarn Y contained in the yarn supplying package Ps2 are knotted, and a knotted portion K is formed.
At time t0 (time ts1), the automatic doffer 10 completes mounting of the winding bobbin Bw1 to the cradle 33, and starts winding the yarn onto the winding bobbin Bw 1. Specifically, the time ts1 is a winding start time when the winding of the yarn Y onto the winding bobbin Bw1 is started. At this time, the yarn Y is unwound from the yarn supply package Ps 1. As time passes, the remaining amount of the yarn Y contained in the yarn supplying 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 automatic doffer 10, and the winding process of the yarn Y on the winding bobbin Bw1 is completed. That is, the time te1 is a winding end time when the winding of the yarn Y onto the winding bobbin Bw1 is ended (the formation of the winding package Pw1 is ended). The remaining amount of the yarn supplying package Ps1 at this time is W1. Only the yarn Y supplied from the yarn supply package Ps1 is wound on the winding bobbin Bw 1. The cutting of the yarn Y by the cutter and the suction and capturing of the yarn Y by the suction device (i.e., the start of the suction and removal of the yarn Y) are performed substantially simultaneously. Then, the winding bobbin Bw1 is removed from the cradle 33. Next, at a time ts2 immediately after the time te1, the mounting of the winding bobbin Bw2 to the cradle 33 is completed, and the winding of the yarn Y onto the winding bobbin Bw2 is started (the winding bobbin replacement operation is completed). For example, the timing at which the body control device 5 outputs the command signal for the winding bobbin replacing operation to the automatic doffer 10 (i.e., the timing at which the winding bobbin replacing operation is started) can be regarded as the winding bobbin replacing timing at which the winding bobbin replacing operation is performed (hereinafter, simply referred to as replacing timing). The replacement timing is equal to the winding end timing (timing te1) of the winding bobbin Bw (in this case, the winding bobbin Bw1) attached to the cradle 33 before the winding bobbin replacement operation. The replacement timing is substantially equal to the winding start timing (timing ts2) of the winding bobbin Bw (in this case, the winding bobbin Bw2) attached to the cradle 33 after the winding bobbin replacement operation.
At a time ta1 after the time ts2, the yarn supply package Ps1 mounted to the 1 st mounting unit 22 becomes empty. That is, the time ta1 is the unwinding end time when the yarn Y is unwound from the yarn supply package Ps 1. At the time tb1 (time ta1), the knotted portion K, which is formed by knotting the yarn Y included in the yarn supplying package Ps1 and the yarn Y included in the yarn supplying package Ps2, is pulled toward the winding device 19 while the yarn supplying package Ps1 is empty. Thus, the yarn Y is unwound from the yarn supply package Ps2 mounted on the 2 nd mounting unit 23 for the first time. That is, the time tb1 is the unwinding start time when the yarn Y is unwound from the yarn supply package Ps2 for the first time (the unwinding of the yarn Y starts). Then, at time te2, the winding process of the yarn Y on the winding bobbin Bw2 (formation of the winding package Pw2) is completed. The remaining amount of the yarn supplying package Ps2 at this time is W2. Both the yarn Y unwound from the yarn supply package Ps1 and the yarn Y unwound from the yarn supply package Ps2 are wound on the winding bobbin Bw 2. The winding package Pw2 includes a knotted portion K. Then, at time ts3, the winding process of the yarn Y on the winding bobbin Bw3 is started. At time te3, when the winding process of the yarn Y onto the winding bobbin Bw3 (formation of the winding package Pw3) is completed, the remaining amount of the yarn feeding package Ps2 is W3. Only the yarn Y supplied from the yarn supply package Ps2 is wound on the winding bobbin Bw 3.
At a time ta2 after the time ta1 and before the yarn supply package Ps2 becomes empty, the bobbin robot 102 removes the yarn supply package Ps1 from the 1 st mounting section 22 and mounts the yarn supply package Ps3 to the 1 st mounting section 22 (yarn supply package replacement operation). The remaining amount of the yarn supply package Ps3 at this time is WF. Then, at an appropriate timing, the terminal end portion of the yarn Y contained in the yarn supply package Ps2 and the starting end portion of the yarn Y contained in the yarn supply package Ps3 are knotted, and a knotted portion K is formed. Here, for convenience of explanation, immediately after the yarn supply package replacement operation by the bobbin robot 102, a knotting operation (connecting operation) is performed by an operator. The operator can perform the knotting operation by hand. Alternatively, the operator may perform the operation of knotting by operating a portable knotting apparatus, not shown, for example. Alternatively, the cylinder robot 102 may have an automatic knotting apparatus (not shown) capable of performing a knotting operation. Thus, the operation of knotting by the cylinder robot 102 can be performed without manual operation.
The following phenomenon will be briefly explained. The phenomenon related to the winding section 4 is as follows. From time ts4 to time te4, the yarn Y is wound around the winding bobbin Bw4 (forming a winding package Pw 4). From time ts5 to time te5, the yarn Y is wound around the winding bobbin Bw5 (forming a winding package Pw 5). From time ts6 to time te6, the yarn Y is wound around the winding bobbin Bw6 (forming a winding package Pw 6). The phenomenon related to the yarn feeding portion 2 is as follows. At a time tb2 (time ta3) between the time ts4 and the time te4, the yarn supply package Ps2 becomes empty, and unwinding of the yarn Y from the yarn supply package Ps3 is started. Then, at a time tb3, the yarn supply package Ps2 is replaced with the yarn supply package Ps 4. At a time ta4 (at a time tb4) between the times ts6 and te6, the yarn supply package Ps3 becomes empty, and unwinding of the yarn Y from the yarn supply package Ps4 is started.
(overview of basic information acquired by the information management section)
In consideration of the above phenomenon, first, an outline of basic information acquired by the information management unit 110 for various determinations and/or calculations will be described with reference to (a) and (b) of fig. 6. Fig. 6 (a) is a table showing the relationship between the yarn feeding package individual information described later and the information at various times, and fig. 6 (b) is a table showing the relationship between the winding package individual information described later and the information at various times.
The information management unit 110 acquires, as basic information, the individual yarn supply package information, the unwinding start time information, and the unwinding end time information in association with each other for each yarn supply package Ps (see fig. 6 (a)). The information management unit 110 also acquires, as basic information, individual winding package information and replacement time information in association with each other for each winding package Pw (see fig. 6 (b)). Details of the method of acquiring such information will be described later. These pieces of information are at least information for associating the individual information of the yarn supplying package Ps, that is, the individual information of the yarn supplying package Ps, with the individual information of the winding package Pw, that is, the individual information of the winding package Pw.
The yarn supply package individual information is identification information applied to each of the plurality of yarn supply packages Ps. Each yarn supply package Ps is attached with, for example, an ID tag, not shown, indicating the yarn supply package individual information. The yarn supply package individual information is used to identify the yarn supply package Ps mounted on each package mounting portion 21. The unwinding start time information is information of the aforementioned unwinding start time. The unwinding start time is, for example, tb1, ta3, tb4 described above. The unwinding end time information is the information of the aforementioned unwinding end time. The unwinding end time is, for example, the above-described time ta1, tb2, ta 4. The winding package individual information is identification information applied to each of the plurality of winding packages Pw. The replacement time information is information of the replacement time. The replacement time is, for example, the above-described time te1 to te 6. As will be described later, the replacement time can be handled as both the 1 st replacement time and the 2 nd replacement time.
(information required)
Next, information necessary for the information management unit 110 to actually acquire the individual yarn supply package information, the unwinding start time information, the unwinding end time information, the individual winding package information, and the replacement time information will be described. More specifically, information on the yarn supplying package Ps attached to and detached from the package mounting unit 21, information on the winding package Pw, and information acquired by the body control device 5 during the winding process will be described.
(information on yarn supply package conveyed by bobbin robot)
The information management unit 110 manages the individual information of the yarn supply package Ps conveyed by the bobbin robot 102 and the information related thereto as follows. First, before or when the full yarn feed package Ps stored in the yarn feed package storage unit is loaded on the bobbin robot 102 by the operator, the yarn feed package individual information corresponding to the yarn feed package Ps is input to the bobbin control device 102a by the operator. For example, the operator can input the individual information of the yarn supply package by reading the ID tag attached to each yarn supply package Ps using an ID reader (not shown) electrically connected to the bobbin control device 102 a. Alternatively, the operator may input the individual information of the yarn feeding package by operating the bobbin control device 102a based on the information that can be visually recognized and is displayed on each yarn feeding package Ps. Alternatively, an ID reader, not shown, may be provided to the cylinder robot 102, and the cylinder robot 102 may read the ID tag using the ID reader.
The information management unit 110 receives the individual information of the yarn feeding package Ps from the bobbin control device 102a when the bobbin robot 102 mounts the yarn feeding package Ps to the package mounting section 21. Then, the information management unit 110 associates the individual information of the yarn supply package Ps with the individual information of the package mounting portion 21 to which the yarn supply package Ps is mounted (see fig. 7 (a)). The individual information of the package mounting portion 21 is information on which of the plurality of spindles 9 the package mounting portion 21 mounted to the yarn supply package Ps belongs to and which of the 1 st mounting portion 22 and the 2 nd mounting portion 23 the package mounting portion 21 belongs to. In this way, the information management unit 110 manages the individual information of the yarn feeding package Ps conveyed by the tube sub robot 102 in association with the operation of the tube sub robot 102.
The body control device 5 acquires the yarn supply package mounting time information related to the yarn supply package mounting time at which the new yarn supply package Ps is mounted on the package mounting portion 21, when the new yarn supply package Ps is mounted on the package mounting portion 21. The yarn supply package mounting timings are, for example, the timings ta2 and tb 3. The body control device 5 stores the yarn supply package individual information, the individual information of the package mounting unit 21, and the yarn supply package mounting time information in association with each other for each yarn supply package Ps (see fig. 7 (a)). (in fig. 7 (a), the yarn supply package mounting timing is simply referred to as mounting timing).
After a new yarn supply package Ps is mounted on one package mounting portion 21, the operator forms a knotted portion K by knotting the leading end portion of the yarn Y contained in the yarn supply package Ps mounted on the other package mounting portion 21. Then, the operator disposes the knot portion K at a predetermined position. The operator inputs information indicating that the knotted portion K is arranged at a predetermined position to the machine body control device 5. Based on the input information, the body control device 5 stores information indicating that the knotted portion K is arranged at a predetermined position.
(information on winding Package)
The information management unit 110 manages individual information of the winding package Pw as follows. The body control device 5 stores the time when the signal for replacing the winding bobbin Bw is output to the automatic doffer 10 as the replacement time. The replacement timing of the winding bobbin Bw newly mounted on the cradle 33 is substantially equal to the winding start timing at which the winding of the yarn Y onto the winding bobbin Bw is started. Such replacement timing is treated as the 1 st replacement timing regarding the winding bobbin Bw (winding package Pw). The body control device 5 is configured to apply individual information (winding package individual information) to the winding package Pw when the winding process of the yarn Y on the winding bobbin Bw is completed (when the formation of the winding package Pw is completed). Specifically, the machine body control device 5 acquires, as the individual information of the winding package Pw, for example, information of a machine body number (identification number of the false twisting machine 1) and information of an identification number of the spindle 9. The body control device 5 stores the time when the signal for removing the winding package Pw from the winding device 19 is output to the automatic doffer 10 as the 2 nd replacement time. The machine body control device 5 stores the information of the machine body number and the identification number of the spindle 9, the information of the 1 st replacement time (the 1 st replacement time information), and the information of the 2 nd replacement time (the 2 nd replacement time information) in association with each other. Both the 1 st replacement time information and the 2 nd replacement time information are included in the replacement time information. The machine body control device 5 may acquire a predetermined management number in association with these pieces of information as the winding package individual information and may assign the winding package Pw to each winding package. For example, when the above-described "Pw 1" to "Pw 6" are management numbers (winding package individual information) as shown in fig. 6 b, the management numbers are associated with the 1 st replacement time and the 2 nd replacement time (the machine body numbers and the identification numbers of the spindles 9 are not shown). The device control apparatus 5 prints the information on a not-shown sign. The label can be attached to the winding bobbin Bw by an operator.
As another means for acquiring the winding package individual information, for example, an ID tag, not shown, may be attached to the empty winding bobbin Bw in advance. Thus, the individual winding information can be applied to the winding bobbin Bw before the winding process. The automatic doffer 10 may have an ID reader not shown. For example, when the automatic doffer 10 mounts a certain winding bobbin Bw to the winding device 19 or removes the winding package Pw from the winding device 19, the ID reader may read the ID tag attached to the certain winding bobbin Bw, thereby transmitting the individual information of the certain winding bobbin Bw to the body control device 5. Alternatively, instead of the automatic doffer 10, an operator may read the ID tag by an ID reader not shown. Alternatively, instead of reading the ID tag by the ID reader, the operator may manually input the individual information of the winding bobbin Bw to the body control device 5.
As described above, the replacement time information includes both the 1 st replacement time information and the 2 nd replacement time information. As a specific example, attention is paid to time te 1. The time te1 is a time when a command signal for starting the replacement operation of the winding bobbin Bw1 (the winding package Pw1) and the new winding bobbin Bw2 (the winding package Pw2) in which the winding process of the yarn Y is completed is output from the body control device 5. The time te1 is equal to the winding end time of the winding package Pw1 and substantially equal to the winding start time of the winding package Pw 2. Therefore, as shown in fig. 6 (b), the information management unit 110 treats the information at the time te1 as the 1 st replacement time information, and associates the 1 st replacement time information with the individual winding package information of the winding package Pw 2. That is, the time te1 is treated as the 1 st replacement time related to the winding package Pw 2. The information management unit 110 also processes the information at the time te1 as the 2 nd replacement time information, and associates the 2 nd replacement time information with the winding package individual information of the winding package Pw 1. In this case, the time te1 is treated as the 2 nd replacement time related to the winding package Pw 1. The 1 st replacement time information and the 2 nd replacement time information are similarly acquired in the other winding package Pw.
The 1 st replacement timing regarding a certain winding bobbin Bw (the winding package Pw) can be used as a winding bobbin attachment timing at which the winding bobbin Bw is attached to the cradle 33. The 2 nd replacement timing regarding a certain winding bobbin Bw (the winding package Pw) can be used as a winding bobbin removal timing at which the winding bobbin Bw is removed from the cradle 33. In other words, the 1 st replacement time information can be used as the winding start time information concerning the winding start time of the winding bobbin Bw. The 2 nd replacement time information can be used as winding end time information related to the winding end time of the winding bobbin Bw. The information management unit 110 may process the 1 st replacement time information as the winding start time information and the 2 nd replacement time information as the winding end time information. Alternatively, the information management unit 110 may obtain more accurate information on the winding start time and/or the winding end time by performing predetermined calculation on the replacement time.
(information obtained by the body control apparatus in the winding process)
Next, information acquired by the body control device 5 in the winding process of the yarn Y onto the winding bobbin Bw will be described. These pieces of information are information for obtaining the individual yarn supply package information, the unwinding start time information, and the unwinding end time information in association with each other by combining the pieces of information described in fig. 7 (a).
The machine body control device 5 determines whether or not the yarn supply package switching in which the yarn supply package Ps for supplying the yarn Y is switched occurs based on the detection result of the yarn detection sensor 24. For example, referring to fig. 5 (a) and (b), the yarn supply package switching is a phenomenon in which the yarn Y is unwound from the yarn supply package Ps2 for the first time while the yarn supply package Ps1 is empty. When the state of the yarn detection sensor 24 is switched from the state in which the yarn Y is detected by one of the 1 st detection unit 25 and the 2 nd detection unit 26 to the state in which the yarn Y is detected by the other of the 1 st detection unit 25 and the 2 nd detection unit 26, the machine body control device 5 determines that the yarn supply package switching has occurred. The machine body control device 5 acquires and stores the following information shown in the table (b) of fig. 7 when determining that the yarn supply package switching has occurred. The body control device 5 stores individual information (either the 1 st mounting unit 22 or the 2 nd mounting unit 23) of the package mounting unit 21 that starts supplying the yarn Y when the yarn supply package switching occurs, in association with the timing when the yarn supply package switching occurs. The package mounting section 21 for starting the supply of the yarn Y treats the timing when the supply package switching occurs as the unwinding start timing. The machine body control device 5 stores the individual information of the package mounting section 21 in which the supply of the yarn Y is completed when the yarn supply package switching occurs, in association with the timing at which the yarn supply package switching occurs. The package mounting section 21 on which the supply of the yarn Y is completed treats the timing at which the yarn supply package switching occurs as the unwinding completion timing.
(method of acquiring unwinding Start time information and unwinding end time information)
Next, a method of acquiring the unwinding start time information and the unwinding end time information based on the information acquired by the machine body control device 5 will be described with reference to fig. 5 (a) and (b), fig. 7 (a) and (b), and fig. 8. Fig. 8 is a table showing the relationship between the individual yarn supply package information, the package mounting section, and various timings.
The machine body control device 5 acquires the unwinding start time information and the unwinding end time information in the following procedure using the yarn supply package mounting time information and the yarn supply package switching information. Specifically, when acquiring the unwinding start time and the unwinding end time of the yarn supply package Ps3, the body control device 5 acquires the individual information (the 1 st mounting section 22) of the package mounting section 21 to which the yarn supply package Ps3 is mounted and the information of the yarn supply package mounting time (time ta2) based on the yarn supply package mounting time information. Next, the body control device 5 acquires information of the earliest time (time ta3, see fig. 5 (a) and (b)) of the unwinding start time of the yarn supply package Ps mounted in the 1 st mounting portion 22, which is later than the time ta2, as the unwinding start time of the yarn supply package Ps 3. The machine body control device 5 acquires information of the unwinding end time (time ta4) associated with the unwinding start time as the unwinding end time of the yarn supply package Ps 3. In this way, the individual information of the yarn supply package Ps is acquired in association with the unwinding start time information and the unwinding end time information. In other words, the unwinding start time information and the unwinding end time information of the yarn supply package Ps are acquired by associating the yarn supply package mounting time information of a certain yarn supply package Ps with the information of the time at which the yarn supply package switching occurs at the earliest after the yarn supply package mounting time (see fig. 8). The information described above can be acquired for each yarn supply package Ps without being limited to the yarn supply package Ps 3.
As described above, the unwinding start time information and the unwinding end time information are acquired by the machine body control device 5. The machine body control device 5 can acquire the unwinding start time information and the unwinding end time information at arbitrary timings. For example, the machine body control device 5 may acquire the unwinding start time information and/or the unwinding end time information at the timing when the yarn supply package switching occurs. Alternatively, the machine body control device 5 may be configured to acquire the unwinding start time information and/or the unwinding end time information using the yarn supply package mounting time information and the yarn supply package switching information acquired in the past when an operation is performed by an operator at an arbitrary timing. Further, the management device 101 may acquire the unwinding start time information and/or the unwinding end time information.
(correlation between winding package individual information and yarn supply package individual information)
Next, a method of associating the winding package individual information with the yarn feeding package individual information will be described. For a specific correlation between the winding package individual information and the yarn feeding package individual information, refer to a table shown in fig. 9. In the following method, for example, the management apparatus 101 acquires the related information, but the method is not limited thereto. That is, the body control device 5 may acquire the information.
As a related specific example, the following describes the 1 st and 2 nd specific examples. As a specific example of the first example 1, when acquiring the individual information of the yarn supply package Ps in which the yarn Y is supplied to the winding bobbin Bw3 (the winding package Pw3), the management device 101 first acquires information of the 1 st replacement time (time te2) and the 2 nd replacement time (time te3) with respect to the winding bobbin Bw3 (the winding package Pw 3). The 1 st replacement timing can be handled as a winding bobbin installation timing or a winding start timing. The 2 nd replacement timing can be handled as the winding bobbin removal timing or the winding completion timing. Next, the management device 101 associates the individual information of the wire supply package Ps (the wire supply package ps2, see fig. 6 b) associated with the newest unwinding start time (time tb1, see fig. 5 b) before the time te2 with the individual information of the winding package Pw 3. In other words, the management device 101 identifies the 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. Then, the management device 101 determines whether or not the yarn supply package is switched between the time te2 and the time te 3. In this example, there is no timing at which the switching of the yarn supply package occurs between the time te2 and the time te3 (i.e., the unwinding start time). Therefore, the management device 101 determines that the yarn feeding package switching does not occur between the time te2 and the time te 3. Thus, information that only the yarn Y from the yarn supplying package Ps2 is supplied to the winding package Pw3 is acquired (see fig. 9).
As a specific example of the second embodiment, the management device 101 is configured to acquire the individual information of the yarn supply package Ps in which the yarn Y is supplied to the winding bobbin Bw4 (the winding package Pw4), and first acquire information of the 1 st replacement time (time te3) and information of the 2 nd replacement time (time te4) of the winding bobbin Bw4 (the winding package Pw 4). Next, the management device 101 associates the individual information of the wire supply package Ps (the wire supply package ps2, see fig. 6 b) associated with the newest unwinding start time (time tb1, see fig. 5 b) before the time te3 with the individual information of the winding package Pw 4. Then, the management device 101 determines whether or not the yarn supply package is switched between the time te3 and the time te 4. In this example, there is a timing (i.e., an unwinding start timing) at which the yarn package switching occurs between the time te3 and the time te4 (time ta 3). Therefore, the management device 101 determines that the yarn package switching has occurred between the time te3 and the time te 4. Based on this determination, the management device 101 associates the individual information of the yarn supplying package Ps (the yarn supplying package ps3, see fig. 6 (b)) associated with the time ta3 with the individual information of the winding package Pw 4. In other words, the management device 101 associates the individual information of the yarn supply package Ps associated with the unwinding start time between the 1 st replacement time and the 2 nd replacement time, among the individual information of the plurality of yarn supply packages Ps, with the individual information of the winding package Pw associated with the 1 st replacement time. Thus, information that the yarn Y is supplied from the yarn supplying package Ps2 and the yarn supplying package Ps3 to the winding package Pw3 is obtained (see fig. 9).
(judgment of the Presence or absence of knotted portion)
The management device 101 performs the following determination based on whether or not the yarn supply package switching occurs. For example, when the management device 101 determines that the yarn feeding package switching has not occurred from the 1 st replacement time (time te2) to the 2 nd replacement time (time te3) with respect to the winding bobbin Bw3 (the winding package Pw3), it determines that the winding package Pw3 does not include the knotted portion K (see fig. 9). When the management device 101 determines that the yarn supplying package switching has occurred from the 1 st replacement time (time te3) to the 2 nd replacement time (time te4) with respect to the winding bobbin Bw4 (the winding package Pw4), it determines that the winding package Pw4 includes the knotted portion K (see fig. 9).
The management device 101 then estimates the mixing position of the knotted portion K in the winding package Pw by performing the following calculation. As a simple example, the management device 101 calculates a ratio of the time from the time te3 to the time at which the yarn package switching occurs (time ta3) to the time from the 1 st replacement time (time te3) to the 2 nd replacement time (time te4) with respect to the winding bobbin Bw4 (the winding package Pw 4). That is, the ratio of ta3-te3 to te4-te3 was calculated. When the value is, for example, N percent, it can be estimated that the knotted portion K is mixed into the winding package Pw4 when the N percent yarn Y is wound around the winding bobbin Bw 4.
(output of chart)
The information management unit 110 also outputs a chart described below. The information management unit 110 creates graph data indicating the unwinding period for each yarn supply package Ps and the winding period for each winding package Pw, using the yarn supply package individual information, the unwinding start time information, the winding package individual information, and the replacement time information. The unwinding period is a period from the start of unwinding the yarn Y from the yarn supply package Ps to the end of unwinding. The winding period is a period from the start of winding the yarn Y on the winding bobbin Bw to the end of winding. The information management unit 110 displays (outputs), for example, graphs (charts) such as those shown in (a) to (c) of fig. 5 on the management output unit 101b (display) of the management device 101, based on the created graph data. The management device 101 corresponds to an output control unit of the present invention. The management output unit 101b corresponds to an output unit of the present invention. The type of the graph is not limited to the above, and a graph in which the unwinding period of each yarn supplying package Ps and the winding period of each winding package Pw can be visually confirmed by an operator may be output. Thus, the operator can easily associate the yarn feeding package individual information with the winding package individual information. The graph may show more detailed information in addition to the information shown in (a) to (c) of fig. 5. For example, the individual information of the yarn supplying package Ps associated with a certain winding package Pw may be displayed together at a position where the individual information of the winding package Pw is displayed. Further, the information indicating which layer of the yarn Y contained in the yarn supplying package Ps the yarn Y is supplied to the certain winding package Pw may be displayed together with the yarn supplying package individual information. In the case where the management output unit 101b includes a printer, the information management unit 110 may be a printer print chart. Alternatively, the information management unit 110 may output (display) the chart to the body output unit 5b of the body control device 5. Alternatively, the output control unit for creating the graph data and the output unit for outputting the graph 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, the winding start time and the winding end time can be known for each winding package Pw. Thus, various information can be acquired about the relationship between the winding bobbin Bw (the winding package Pw) and the yarn feed package Ps. For example, it is possible to know which layer of the yarn Y is formed in the yarn supplying package Ps in a certain winding package Pw. Further, it is possible to determine whether or not the knotted portion K is mixed into the winding package Pw. In this case, it is possible to further know the position of the winding package Pw where the knotted portion K is mixed. In this way, various useful information can be derived.
Further, using the unwinding start time information and the replacement time information, it can be easily known that the knotted portion K is mixed in the winding package Pw.
Further, by using the calculation of the 1 st replacement time, the 2 nd replacement time, and the unwinding start time, the mixing position of the knotted portion K in the winding package Pw can be easily known.
The individual yarn supply package information and the unwinding start time information are acquired in association with each other. Thus, by considering the front-rear relationship at each time, it is possible to know from which yarn supply package Ps the yarn Y is supplied to a certain winding bobbin Bw.
Further, the operator can easily associate the winding package individual information with the yarn feeding package individual information by simply observing the outputted chart.
Further, the individual information of the predetermined winding package Pw and the individual information of the yarn feed package Ps for supplying the yarn Y when the winding of the yarn to the predetermined winding package Pw is started can be automatically associated with each other.
Further, when the yarn Y is supplied from the plurality of yarn supplying packages Ps to a certain winding bobbin Bw in sequence, the individual information of all the plurality of yarn supplying packages Ps and the individual information of the certain winding package Pw can be automatically associated with each other.
When the yarn supply package Ps is mounted to the package mounting portion 21 by the bobbin robot 102, the yarn supply package individual information and the package mounting portion 21 can be automatically associated with each other.
The yarn detection sensor 24 can constantly determine from which of the package mounting portions 21 the yarn is being supplied. Accordingly, the association between the individual yarn supply package information and the unwinding start time information can be automatically and accurately achieved.
Next, a modified example obtained by modifying the above embodiment will be described. However, the same reference numerals are given to portions having the same configuration as in the above embodiment, and the description thereof will be omitted as appropriate.
(1) In the above embodiment, whether or not the yarn feeding package is switched is determined based on the detection result of the yarn detecting sensor 24 having the 1 st detecting section 25 and the 2 nd detecting section 26, but the present invention is not limited thereto. For example, as shown in fig. 10, the yarn feeder 2a of the false twist texturing machine 1a may have a switching detector 41 having a different configuration from the yarn detecting sensor 24 for each spindle 9 a. The switching detector 41 may include, for example, a supply sensor 42 and a knot sensor 43. The supply sensor 42 is configured to be able to detect whether the yarn Y is being supplied from the 1 st mounting portion 22. The knot portion sensor 43 is configured to be able to detect the knot portion K arranged in a stationary manner at a predetermined position. In such a configuration, when the knotted portion K moves from the predetermined position and the knotted portion sensor 43 cannot detect the knotted portion K, it can be determined that the yarn package switching has occurred. Further, it can be known from which of the 1 st mounting unit 22 and the 2 nd mounting unit 23 the yarn Y is being supplied at the time of switching of the yarn feeding package, based on the detection result of the supply sensor 42. In this way, even when the detection result of the knotted portion K is used, it can be reliably known from which of the 1 st attaching part 22 and the 2 nd attaching part 23 the yarn Y is being supplied. The knot sensor 43 may be configured to detect the moving knot portion K. .
(2) In the embodiments described above, the information management unit 110 determines whether or not the yarn feeding package switching occurs based on the detection result of the yarn detecting sensor 24 or the switching detection unit 41, but the present invention is not limited thereto.
(3) In the embodiments described above, the information management unit 110 acquires the unwinding start time information and the unwinding end time information based on the yarn supply package mounting time information and the yarn supply package switching time information. That is, the information management unit 110 associates the yarn supply package mounting time with the unwinding start time. However, the present invention is not limited thereto. When the yarn supply package switching is to be performed, the information management unit 110 may associate the individual information of the package mounting section 21 on which the supply of the yarn Y is started, the individual information of the yarn supply package Ps mounted on the package mounting section 21, and the unwinding start time (i.e., the switching time) of the yarn supply package mounting section 21. This also makes it possible to acquire the unwinding start time information. In this case, the information management unit 110 does not necessarily acquire the information of the yarn supply package mounting timing. That is, the information management unit 110 may be configured to acquire only the individual information of the yarn supply package Ps in association with the individual information of the package mounting portion 21 when the yarn supply package Ps is mounted to the yarn supply package holding portion 20.
(4) In the embodiments described above, the information management unit 110 performs various associations and/or acquisition of various information based on the winding start time information, the winding end time information, the unwinding start time information, and the unwinding end time information, but the present invention is not limited thereto. That is, the information management unit 110 may acquire only the yarn supply package individual information, the unwinding start time information, and the unwinding end time information in association with each other, and may acquire the winding package individual information in association with the replacement time information. Using these pieces of information, various useful information can be obtained by another computer device (not shown).
(5) In the embodiments described above, the information management unit 110 acquires the unwinding end information, but is not limited to this. That is, the unwinding start time of a certain yarn supply package Ps is the unwinding end time of the yarn supply package Ps from which the yarn Y is supplied to the point before the yarn Y starts to be unwound from the yarn supply package Ps. Based on this fact, the unwinding start time information of a certain yarn supply package Ps (e.g., the yarn supply package Ps2) may be used as the unwinding end information of another yarn supply package Ps (e.g., the yarn supply package Ps 1). However, in such a configuration, the steps of various determinations and/or calculations become complicated. Thus, the recommendation information management unit 110 acquires the unwinding end information to simplify various determinations and/or calculations.
(6) In the embodiments described above, the yarn supply package replacement operation is performed by the bobbin robot 102. Further, the winding bobbin replacing operation is performed by the automatic doffer 10. However, the present invention is not limited thereto. The yarn supply package replacement operation may be performed by an operator. The operator may input necessary information such as information on the individual yarn supply package to the body control device 5. The mounting and dismounting operation of the winding bobbin Bw may be performed by an operator. The operator may input necessary information such as winding individual information to the machine control device 5.
(7) In the embodiments described above, the information management unit 110 acquires the yarn supply package individual information and the unwinding start time information in association with each yarn supply package Ps, but the present invention is not limited thereto. The information management unit 110 does not necessarily acquire the individual yarn supply package information and the unwinding start time information in association with each other. For example, the information management unit 110 may acquire the unwinding start time information only for each yarn supply package Ps without acquiring the individual yarn supply package information. Even when such processing is performed, by using the unwinding start time information and the replacement time information, it is possible to acquire various useful information such as whether or not the information of the knotted portion K is included in the winding package Pw.
(8) In the embodiments described above, the body control device 5 acquires, as the replacement time information, information of the time at which the signal for causing the automatic doffer 10 to perform the winding bobbin replacement operation is output. However, the present invention is not limited thereto. For example, the body control device 5 may be configured to be able to detect and/or determine the completion of the winding bobbin replacing operation. Then, the machine body control device 5 may acquire information on the time when the winding bobbin replacement operation is completed as replacement time information.
(9) In the above-described embodiments, the information management unit 110 includes the plurality of body control devices 5 and the management device 101, but is not limited thereto. That is, the information management unit 110 may include a computer device (not shown) other than the body control device 5 and the management device 101. Alternatively, the information management unit 110 may include only the body control device 5 or the management device 101. That is, only one of the body control apparatus 5 and the management apparatus 101 may acquire necessary information.
(10) In the embodiments described above, the yarn processing apparatus 100 includes the plurality of false twist processors 1, but is not limited thereto. The yarn processing apparatus 100 may have only one false twist processing machine 1. Further, the management apparatus 101 may not be provided. In this case, the false twist texturing machine 1 corresponds to the yarn texturing apparatus of the present invention. The false twist texturing machine 1 includes a plurality of spindles 9, but is not limited thereto. That is, the number of the spindles 9 included in the false twist processing machine 1 may be one. In other words, the yarn supply package holding section 20 of the yarn supply section 2 may be one in number.
(11) The present invention may be applied to other yarn processing apparatuses including a yarn processing machine instead of the yarn processing apparatus 100 including the false twist processing machine 1. For example, the present invention can be applied to a yarn processing apparatus provided with an air flow processing machine (yarn processing machine) described in japanese patent application laid-open No. 2002-088605.
