Description

Wire processing equipment

This invention relates to a wire processing device.

Patent document 1 discloses a wire processing machine (wire processing equipment) that processes wire unwound from a spinning end product (a wire feed roll formed by winding wire onto a wire feed bobbin) and winds it onto a take-up bobbin to form a wire processing end product (take-up roll). The wire processing equipment is configured to support two wire feed rolls (e.g., a first wire feed roll and a second wire feed roll) corresponding to one take-up bobbin. In this wire processing equipment, when the end of the wire in one of the first and second wire feeding spools is knotted (connected) to the beginning of the wire in the other, wire can be continuously supplied from the other spool even after one spool becomes empty. Specifically, after the wire supply from one spool ends, the knotted portion (wire connection portion) of the two wires is pulled, thereby starting the unwinding of the wire from the other spool. This allows for an uninterrupted wire supply.

Furthermore, the mechanical control unit that controls the aforementioned yarn processing equipment is configured to determine from which yarn supply roll a particular take-up roll is supplied with yarn (i.e., to associate the individual information of the take-up roll with the individual information of the yarn supply roll). Specifically, an identification device reads tags indicating the individual information of each yarn supply roll and position identification tags indicating the positions of the roll mounting sections (first mounting section and second mounting section) used to mount the yarn supply rolls. Then, based on the identification result of the identification device, the individual information of the yarn supply rolls is associated with the roll mounting sections. In addition, the yarn processing equipment is equipped with a detector for detecting knotted portions. The mechanical control unit, knowing from which feed roll is the yarn being supplied (e.g., knowing that the yarn is being supplied from the first feed roll), makes the following determination: If no knot is detected by the detector during the period from the start to the end of winding the yarn into the take-up bobbin, it determines that only the yarn contained in the first feed roll is supplied to the take-up bobbin. Furthermore, if a knot is detected by the detector during the period from the start to the end of winding the yarn into the take-up bobbin, it determines that both the yarn contained in the first feed roll and the yarn contained in the second feed roll are supplied to the take-up bobbin.

Patent Document 1: International Publication No. 2020/127489

As mentioned above, based on the identification results of the identification device and the detection results of the detector, information relating the individual information of the winding package and the individual information of the supply package can be obtained. However, based solely on these identification and detection results, it is difficult to extract more detailed information.

The purpose of this invention is to extract various useful information from a wire processing device capable of continuously supplying wire.

The first invention discloses a wire processing apparatus comprising: a wire processing machine having a wire supply unit configured to supply wire; a processing unit configured to process the wire supplied from the wire supply unit and a winding unit for winding the wire processed by the processing unit onto a winding spool to form a winding package; and an information management unit configured to manage information related to the wire processing machine. The wire processing apparatus is characterized in that: the wire supply unit comprises multiple mounting units capable of assembling and disassembling multiple wire supply packages; the terminal end of the wire contained in the wire supply package mounted in one of the multiple mounting units; and a connection point for wire supply packages mounted in mounting units other than the one mounting unit among the multiple mounting units. In the case of the starting end of the yarn contained in the package, the yarn can be supplied continuously. The winding unit is configured to start winding yarn into a new winding spool after the yarn winding into a certain winding spool has ended. The information management unit is able to obtain and start the supply of yarn in the yarn supply unit for each yarn supply package. The system provides unwinding start time information related to the start time of unwinding the yarn in the yarn package, and can obtain individual package information for each package by winding the yarn into the winding bobbin installed in the winding unit, as well as replacement time information related to the replacement time when the winding bobbin is changed in the winding unit.

In this invention, the unwinding start time of each yarn supply package is obtained. Furthermore, in this invention, the replacement time of each take-up bobbin is obtained. Therefore, the moment a take-up bobbin is installed in the take-up section can be treated as the start time for winding yarn onto that take-up bobbin. Moreover, the moment when that take-up bobbin is replaced with the next take-up bobbin (i.e., the moment that take-up bobbin is removed from the take-up section) can be treated as the end time for winding yarn onto that bobbin and completing the winding of the package. Thus, the winding start time and winding end time can be determined for each take-up bobbin (winding package).

Therefore, in this invention, various information regarding the relationship between the take-up bobbin (take-up package) and the feed package can be obtained. For example, by performing calculations using information from various moments, it can be determined which layer of the feed package's yarn forms a particular take-up package. Furthermore, for example, if there is an unwinding start moment between the start and end moments of take-up for a particular take-up package, it can be determined that a yarn connection portion, formed by the connection between the end and start ends of the yarn, is mixed into that particular take-up package. Moreover, in this case, it can also be determined at which position the yarn connection portion is mixed into that particular take-up package. Thus, various useful information can be derived.

The second invention's feature of the wire processing equipment is that, in the first invention, the information management unit, based on the unwinding start time information and the replacement time information, determines that, in the case where an unwinding start time exists between the designated first replacement time when the take-up bobbin is installed in the take-up section and the designated second replacement time when the take-up bobbin is removed from the take-up section, a wire connection portion connecting the start end and the end end is mixed into the designated take-up package formed by winding wire onto the designated take-up bobbin.

In this invention, by utilizing unwinding start time information and change time information, it is easy to determine whether there are filamentous connecting parts mixed in during the winding process.

The third invention's feature of the wire processing equipment is that, in the second invention, the information management unit infers the location of the mixed-in wire connection portion in the specified take-up package based on the first changeover time, the second changeover time, and the unwinding start time.

In this invention, by calculating the first changeover time, the second changeover time, and the unwinding start time, the location of the mixed-in yarn at the thread connection point in the winding package can be easily determined.

The fourth invention's thread processing equipment is characterized in that, in any of the first to third inventions above, the information management unit is able to obtain, in association with each thread supply roll, individual information about the thread supply roll installed in the thread supply unit, and the unwinding start time information.

In this invention, information about the individual yarn feed roll and the unwinding start time are obtained in a correlated manner. Therefore, by considering the sequential relationship between each moment, it can be determined from which yarn feed roll a given take-up bobbin receives the yarn.

The fifth invention's yarn processing apparatus is characterized by comprising, in the fourth invention, an output unit capable of outputting information, and an output control unit controlling the output unit. The output control unit uses the individual information of the yarn supply package; the unwinding start time information; the individual information of the winding package; and the changeover time information to generate chart data indicating the unwinding period from the start of unwinding to the end of unwinding for each yarn supply package; and the winding period from the start of winding to the end of winding for each winding package. Based on the chart data, the output unit outputs a chart.

In this invention, operators can easily establish a correlation between the individual information of the take-up package and the individual information of the supply package simply by observing the output charts.

The sixth invention's yarn processing equipment is characterized in that, in the fourth or fifth invention described above, the information management unit, based on the unwinding start time information and the replacement time information, determines the latest yarn supply package to begin unwinding before the first replacement time when the predetermined take-up bobbin is installed in the take-up unit, and establishes a correlation between the yarn supply package's individual information and the take-up package's individual information for the predetermined take-up package formed by winding yarn onto the predetermined take-up bobbin.

In this invention, at least the individual information of a specified take-up package can be automatically linked to the individual information of a supply package that feeds the yarn at the beginning of forming the specified take-up package.

The seventh invention's yarn processing equipment is characterized in that, in the sixth invention, when an unwinding start time exists between the first change time and the second change time when the predetermined take-up package is removed from the take-up unit, the information management unit establishes a correlation between the individual information of the yarn supply package at the unwinding start time and the individual information of the predetermined take-up package.

In this invention, when yarn is sequentially supplied from multiple yarn feed rolls during the formation of a take-up roll, it is possible to automatically establish a correlation between all individual information of the multiple yarn feed rolls and the individual information of the specific take-up roll.

The filament processing equipment of the eighth invention is characterized by comprising, in any one of the fourth to seventh inventions above, a filament feed roll conveying device configured to convey and detach from the filament feed unit, wherein the information management unit, when a specified filament feed roll is installed by the filament feed roll conveying device into one of the plurality of installation units, establishes a connection between the individual information of the specified filament feed roll and that installation unit.

In this invention, when a wire supply reel is installed from the wire supply reel conveyor to the installation unit, individual information of the wire supply reel can be automatically linked to the installation unit.

The filament processing apparatus of the ninth invention is characterized by comprising, in any one of the inventions 4 to 8 above, a detection unit capable of detecting which of the plurality of installation units is currently unwinding the filament feed roll, and the information management unit, based on the detection result of the detection unit, establishing a correlation between the individual information of the filament feed roll and the unwinding start time information.

In this invention, by utilizing the detection results of the detection unit, it is possible to easily establish a correlation between individual information of the yarn supply roll and the unwinding start time information.

Furthermore, for example, when the yarn processing machine starts operating, yarn can be fed from any of the multiple yarn feed spools installed in the yarn feed section. In this case, in a configuration without the aforementioned detection unit, it is difficult to automatically determine which yarn feed spool is being fed from using only electronic mechanisms. Regarding this, in this invention, the detection unit can continuously determine which of the multiple feed sections is currently feeding yarn. Therefore, it is possible to automatically and accurately link individual yarn feed spool information with unwinding start time information.

(An overview of wire processing equipment)

Next, embodiments of the present invention will be described. The outline of the yarn processing equipment 100 of this embodiment will be described with reference to the schematic plan view of FIG. 1 and the block diagram of FIG. 2 .

The package robot 102 may be configured to transport a plurality of yarn supply packages Ps at a time. The bobbin robot 102 is configured to be movable in a factory where a plurality of false twisting machines 1 are installed. For example, the package robot 102 is configured to be able to reciprocate between a yarn supply package storage unit (not shown) in which the yarn supply package Ps is stored, and each false twisting machine 1 . The bobbin robot 102 is configured so that, for example, an operator can load the yarn supply package Ps accumulated in the yarn supply package storage unit. Alternatively, the package robot 102 may be configured to be able to acquire the yarn supply package Ps accumulated in the yarn supply package storage section without manual operation. The package robot 102 is configured to be able to attach and detach the yarn supply package Ps to the yarn supply section 2 of each false twisting machine 1 . In other words, the bobbin robot 102 is configured to be able to replace the yarn supply package Ps in the yarn supply unit 2 . The package control device 102a that controls the package robot 102 is electrically connected to the management device 101 (see FIG. 2). The package control device 102a receives the command signal sent from the information management unit 110, and controls the package robot 102 based on the command signal.

The take-up package conveying device 103 is configured to collect the take-up package Pw formed in the take-up section 4 of each false twisting machine 1. The winding package conveying device 103 may be configured to convey a plurality of winding packages Pw at a time.

A control device (not shown) that controls the winding package conveying device 103 is electrically connected to the management device 101 . The winding package conveying device 103 receives the command signal sent from the information management unit 110, and collects the formed winding package Pw based on the command signal.

(The overall composition of the false twisting machine)

Next, the overall structure of the false twisting machine 1 will be described with reference to FIGS. 3 and 4 . FIG. 3 is a side view of the false twisting machine 1 . FIG. 4 is a schematic diagram of the false twisting machine 1 unfolded along the path of the yarn Y (the yarn passage). Let the vertical direction on the paper surface of FIG. 3 be the longitudinal direction of the above-mentioned body, and let the left-right direction on the paper surface be the width direction of the body. Let the direction orthogonal to both the body length direction and the body width direction be the up and down direction (vertical direction) where gravity acts. Let the direction in which the yarn Y travels be the yarn travel direction. The false twisting machine 1 is provided with: a yarn supply part 2 for supplying a plurality of yarns Y; a processing part 3 for processing (false twisting) the plurality of yarns Y supplied from the yarn supply part 2; a winding part 4 for winding the plurality of yarns Y processed by the processing part 3 into a winding bobbin Bw; and a machine body control device 5.

The yarn supply section 2 has a creel 6 holding a plurality of yarn supply packages Ps, and supplies a plurality of yarns Y to the processing section 3 . The processing section 3 is configured to unwind a plurality of yarns Y from the yarn supply section 2 and perform processing. The processing section 3 is configured such that a first feed roller 11, a twist-stopping guide 12, a first heating device 13, a cooling device 14, a false twisting device 15, a second feed roller 16, a second heating device 17, and a third feed roller 18 are arranged in this order from the upstream side in the yarn traveling direction. These structural elements in the processing section 3 are provided, for example, on each of a plurality of spindles 9 (see FIG. 4 ) described below. middle. The winding section 4 has a plurality of winding devices 19 . Each winding device 19 winds the yarn Y that has been falsely twisted by the processing unit 3 onto the winding bobbin Bw to form a winding package Pw. Furthermore, in the winding section 4, a plurality of automatic doffing machines 10 for performing the replacement operation of the formed winding package Pw and a new and empty winding bobbin Bw are provided corresponding to the plurality of winding devices 19 respectively.

The machine control device 5 is used to control the various components of the yarn feeding section 2, the processing section 3, and the winding section 4. The machine control device 5 is, for example, a general computer device. The machine control device 5 has a machine input section 5a, a machine output section 5b, and a machine storage section 5c. The machine input section 5a is, for example, a touch panel and/or keyboard (not shown), configured to be operable by an operator. The machine output section 5b is, for example, a display (not shown), configured to output information. The machine output section 5b may also be a printer (not shown). The machine storage section 5c is configured to store various information used to control the components of the yarn feeding section 2, the processing section 3, and the winding section 4. The machine control device 5 controls the components of the yarn feeding section 2, processing section 3, and winding section 4 based on various information. Alternatively, the machine control device 5 can also control the grounding of these components via various control devices (not shown) used to control the individual components of the yarn feeding section 2, processing section 3, and winding section 4. A management device 101, acting as a host computer, is electrically connected to the machine control device 5. The management device 101 can use the information obtained by the machine control device 5 to perform various judgments and/or calculations described later.

The false twisting machine 1 has a main body 7 and a winding table 8 arranged at intervals in the machine body width direction. The main body 7 and the winding table 8 are arranged to extend substantially the same length in the longitudinal direction of the body. Main body 7 and coiling table 8 They are arranged to face each other in the width direction of the body. The false twisting machine 1 has a unit unit called a span including a set of main body 7 and winding table 8 . In one span, each device is arranged so that a plurality of yarns Y traveling in a state aligned in the longitudinal direction of the machine body can be simultaneously subjected to false twist processing. The false twisting machine 1 is arranged so as to be symmetrical in the plane of the drawing with the center line C in the machine width direction of the main body 7 as the axis of symmetry in this span (the main body 7 is common to both left and right spans). In addition, multiple spans are arranged along the length of the body.

In addition, the group of constituent elements through which one yarn Y is supplied from the yarn supply part 2 and passes until it reaches the winding part 4 is called a "spindle". In other words, the false twisting machine 1 has the same number of spindles 9 as the number of winding packages Pw that can be formed simultaneously (see FIG. 4 ). Roughly speaking, the plurality of spindles 9 are arranged in an array along the length direction of the body. As an inclusive relationship, the false twisting machine 1 has a plurality of spans, and each span has a plurality of spindles 9 .

(Silk Supply Department)

The configuration of the wire supply unit 2 will continue to be described with reference to Figures 3 and 4. The bobbin holder 6 of the wire supply unit 2 has multiple wire supply roll holding parts 20 (see Figure 4) respectively provided corresponding to multiple tablets 9. The multiple wire supply roll holding parts 20 are each configured to be able to assemble and disassemble two wire supply rolls Ps. That is, the wire supply roll holding part 20 has two roll mounting parts 21 (mounting parts of the present invention). For ease of explanation, one of the two roll mounting parts 21 is referred to as the first mounting part 22, and the other is referred to as the second mounting part 23. The first mounting part 22 and the second mounting part 23 are each configured to be able to assemble and disassemble one wire supply roll Ps. The assembly and disassembly of the yarn roll mounting section 21 by the aforementioned bobbin robot 102 is performed.

Each yarn supply roll holding part 20 of the yarn supply section 2 is configured to continuously supply yarn Y as follows. For example, as shown in FIG4, a first yarn supply roll PsA (a yarn supply roll of the present invention) as one of a plurality of yarn supply rolls Ps is mounted on the first mounting part 22. In addition, a second yarn supply roll PsB (another yarn supply roll of the present invention) different from the first yarn supply roll PsA is mounted on the second mounting part 23. Yarn Y is unwound from the first yarn supply roll PsA. Furthermore, the terminal end of the yarn Y contained in the first yarn supply roll PsA is knotted (connected) to the starting end of the yarn Y contained in the second yarn supply roll PsB. Thus, a knotted portion K (thread connection portion) is formed between the two threads Y. In this case, after the first thread supply roll PsA becomes empty, thread Y can be continuously supplied from the second thread supply roll PsB. Specifically, after the supply of thread Y from the first thread supply roll PsA ends and the first thread supply roll PsA becomes empty, the knotted portion K is pulled downstream in the thread travel direction (towards the winding device 19), thereby unwinding thread Y from the second thread supply roll PsB. In this way, the thread supply roll Ps that generates the supply of thread Y is switched. Thus, the supply of thread Y is continuously supplied. Then, the empty wire feed roll Ps is replaced by a new wire feed roll Ps by the bobbin robot 102.

A yarn detection sensor 24 (the detection unit of the present invention) is disposed downstream of the yarn travel direction of the yarn feeding coil holding section 20. The yarn detection sensor 24 is configured to detect which of the first mounting section 22 and the second mounting section 23 is supplying yarn Y. As shown in FIG. 4, the yarn detection sensor 24 has a first detection section 25 and a second detection section 26. The first detection section 25 is configured to detect whether yarn Y is being supplied from the first mounting section 22. The second detection section 26 is configured to detect whether yarn Y is being supplied from the second mounting section 23. The first detection section 25 and the second detection section 26 are, for example, optical sensors that optically detect yarn Y. For more details regarding the wire detection sensor 24, please refer, for example, to Japanese Patent No. 5873105. Alternatively, the first detection unit 25 and the second detection unit 26 may also be contact sensors, for example.

(Processing Department)

The configuration of the processing unit 3 will continue to be described with reference to Figures 3 and 4. Hereinafter, only the portion of the processing unit 3 corresponding to a single tablet 9 will be described.

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

The twist-stopping 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 twist-stopping guide 12 in the yarn traveling direction. The twist-stop yarn guide 12 is disposed on the downstream side of the first yarn feeding roller 11 in the yarn traveling direction and on the upstream side of the first heating device 13 in the yarn traveling direction.

The first heating device 13 is configured to heat the yarn Y conveyed from the first yarn feeding roller 11 . The first heating device 13 is disposed on the downstream side of the twist-stop guide 12 in the yarn traveling direction and on the upstream side of the cooling device 14 in the yarn traveling direction. In this embodiment, in order to simplify the description, the first heating device 13 is configured to heat one yarn Y, but the invention is not limited to this. The first heating device 13 may be configured to be able to heat a plurality of yarns Y simultaneously.

The cooling device 14 is configured to heat the The final yarn Y is cooled. The cooling device 14 is disposed on the downstream side of the first heating device 13 in the yarn traveling direction and on the upstream side of the false twisting device 15 in the yarn traveling direction. In this embodiment, in order to simplify the description, the cooling device 14 is configured to cool one yarn Y, but it is not limited to this. The cooling device 14 may be configured to cool a plurality of yarns Y simultaneously.

The false twisting device 15 is configured to apply twist to the yarn Y. The false twisting device 15 is, for example, a so-called friction disk type false twisting device, but is not limited thereto. The false twisting device 15 is disposed on the downstream side of the cooling device 14 in the yarn traveling direction and on the upstream side of the second yarn feeding roller 16 in the yarn traveling direction.

The second yarn feeding roller 16 is configured to convey the yarn Y processed by the false twisting device 15 to the second heating device 17 . The conveyance speed of the yarn Y by the second feed roller 16 is faster than the conveyance speed of the yarn Y by the first feed roller 11 . Thereby, the yarn Y is stretched between the first yarn feeding roller 11 and the second yarn feeding roller 16 .

The second heating device 17 is configured to heat the wire Y conveyed from the second feed roller 16. The second heating device 17 extends along the vertical direction. For simplicity, the second heating device 17 is configured to heat one wire Y, but is not limited thereto. The second heating device 17 may also be configured to heat multiple wires Y simultaneously.

The third feed roller 18 is configured to convey the yarn Y, heated by the second heating device 17, to the winding device 19. The conveying speed of the yarn Y by the third feed roller 18 is slower than that by the second feed roller 16. The yarn Y is relaxed between the second feed roller 16 and the third feed roller 18.

In the processing section 3 configured as above, the yarn Y stretched between the first yarn feeding roller 11 and the second yarn feeding roller 16 is twisted by the false twisting device 15 . The twist formed by the false twist device 15 propagates to the twist-stopping guide 12 and does not propagate to the upstream side of the twist-stopping guide 12 in the yarn traveling direction. The yarn Y which is stretched and twisted is heated and heat-set by the first heating device 13 and then cooled by the cooling device 14 . Downstream of the false twisting device 15, the yarn Y is untwisted, but the state of each filament being falsely twisted into a corrugated shape is maintained by the above-mentioned heat setting. Then, the yarn Y falsely twisted by the false twisting device 15 is relaxed between the second yarn feeding roller 16 and the third yarn feeding roller 18 and heat-set by the second heating device 17, and then is guided to the downstream side in the yarn traveling direction. Finally, the yarn Y sent out from the third yarn feeding roller 18 is wound around the winding bobbin Bw by the winding device 19 . Thereby, the winding package Pw is formed.

(Curling section)

The structure of the winding unit 4 will be described with reference to Figures 3 and 4. The winding unit 4 has multiple winding devices 19 for winding yarn Y onto a winding bobbin Bw and multiple automatic doffing machines 10 corresponding to each winding device 19 (see Figure 3). Each winding device 19 is associated with a multiple ingot 9 in a one-to-one manner (see Figure 4). Each winding device 19 has, for example, a fulcrum guide 31, a traversing device 32, a rocker 33, and a winding roller 34. The fulcrum guide 31 is a guide that serves as a fulcrum when the yarn Y is traversed. The traversing device 32 is configured, for example, to traverse the yarn Y via a traversing guide 35 mounted on a motor-driven reciprocating loop. The rocker 33 is configured to support the take-up spool Bw (take-up package Pw) for free rotation. The take-up roller 34 is configured to rotate the take-up package Pw and apply contact pressure to its surface. The take-up roller 34 is driven by a motor (not shown), for example, in contact with the surface of the take-up package Pw. Thus, the take-up package Pw is driven to rotate by friction, and the shape of the take-up package Pw is adjusted by the applied contact pressure. Alternatively, it can replace the rotational drive of the take-up roller 34, allowing the take-up package Pw to be directly rotated by a motor (not shown).

The automatic doffing machine 10 is configured to remove the take-up package Pw from the take-up device 19 and install an empty take-up bobbin Bw into the take-up device 19. In other words, the automatic doffing machine 10 is configured to replace the completed take-up package Pw with an empty take-up bobbin Bw in the take-up section 4. Furthermore, the automatic doffing machine 10 has a cutter (not shown) near the take-up package Pw that can cut the filament Y. The traveling filament Y is cut by the cutter, thereby ending the formation of the take-up package Pw. Here, even after the cutter cuts the filament, the filament Y continues to be supplied to the take-up device 19. The automatic doffing machine 10 has a suction device (not shown) that, from the completion of the formation of the take-up package Pw until the start of taking up the yarn Y to the next take-up bobbin Bw, can attract and capture the traveling yarn Y supplied to the take-up device 19 and hold it. Before hooking the yarn Y onto the next take-up bobbin Bw to be taken up, the suction device removes the portion of the yarn Y that was attracted by the suction device. Furthermore, the automatic doffing machine 10 has a storage section 10a configured to temporarily store the take-up package Pw removed from the corresponding take-up device 19. The storage section 10a faces, for example, the space formed between the bobbin holder 6 and the take-up table 8. The wound rolls Pw stored in storage section 10a are recovered by the aforementioned wound roll conveying device 103. For more detailed information regarding the structure of the automatic doffing machine 10, please refer to, for example, Japanese Patent Application Publication No. 6-212521.

In the winding section 4 configured as described above, the yarn Y conveyed from the third feed roller 18 is wound onto the winding bobbin Bw by each winding device 19, forming a winding package Pw (winding process). The winding process of the yarn Y onto the winding bobbin Bw ends when the yarn Y is cut by the cutter of the automatic doffing machine 10. Almost simultaneously, the winding package Pw is removed from the cradle 33 by the automatic doffing machine 10. Subsequently, a new empty winding bobbin Bw is installed on the cradle 33 by the automatic doffing machine 10. That is, after a certain take-up package Pw is formed, the take-up package Pw (take-up bobbin Bw) is replaced with a new take-up bobbin Bw by the automatic doffing machine 10 (take-up bobbin replacement operation). This allows the winding of yarn Y to begin on the new take-up bobbin Bw. Furthermore, "subsequently" means "after a very short time compared to the time required from the start of the winding process to the completion of the formation of the take-up package Pw (winding time)." "Subsequently after the formation of the take-up package Pw" can also be interpreted as "approximately at the same time as the completion of the formation of the take-up package Pw."

However, in order to properly manage the quality of the winding package Pw, it is preferable to know from which feed package Ps supplied the yarn Y during the formation of the winding package Pw. To obtain such information, a mechanism for establishing a correlation between the individual information of the feed package Ps and the individual information of the winding package Pw has been proposed in the past. As a specific example of a previous proposal, a label (not shown) that reads the individual information of each feed package Ps, a label (not shown) indicating the location of the first mounting section 22, and a label (not shown) indicating the location of the second mounting section 23 are read by an identification device (not shown). Then, based on the identification result of the identification device, the individual information of the feed package Ps is correlated with the first mounting section 22 or the second mounting section 23. Furthermore, in previous proposals, a detector (not shown) was provided to detect the passage of the knotted portion K. The machine control device 5, for example, performs the following determination when it is known that yarn is being supplied from the first feed package PsA: That is, if the detector does not detect the passage of the knotted portion K during the period from the start of winding yarn Y onto the take-up bobbin Bw to the end of winding, it is determined that only the yarn Y contained in the first feed package PsA is supplied to the take-up bobbin Bw. Furthermore, if the detector detects the passage of a knotted portion K during the period from the start of winding yarn Y onto the take-up spool Bw to the end of winding, it is determined that yarn Y contained in both the first feed spool PsA and the second feed spool PsB are supplied to the take-up spool Bw. Thus, based on the identification results of the identification device and the detection results of the detector, information relating the individual information of the take-up spool Pw to the individual information of the feed spool Ps is obtained. However, based solely on this identification and detection result, it is difficult to derive more detailed information.

Therefore, in this embodiment, in order to extract various useful information, the information management unit 110 acquires the information described below. Specifically, the information management unit 110 acquires and manages various information related to the phenomena shown in the charts of Figures 5(a) to (c). Furthermore, in the following explanation, unless otherwise specified, the description will be limited to the designated tablet 9.

(Specific examples of the phenomenon)

Before providing a detailed explanation of the information obtained by the Information Management Department 110, to aid in understanding the subsequent explanation, the phenomena illustrated in Figures 5(a) to (c) and the times at which each phenomenon occurs will be explained. The Information Management Department 110 obtains information related to at least a portion of the phenomena shown in Figures 5(a) to (c) (details will be described later).

Figure 5(a) is a graph showing the relationship between the remaining amount (vertical axis) and time (horizontal axis) of the filament Y contained in the filament supply rolls Ps (specifically filament supply rolls Ps1 and Ps3) installed in the first mounting section 22. Figure 5(b) is a graph showing the relationship between the remaining amount (vertical axis) and time (horizontal axis) of the filament supply rolls Ps (specifically filament supply rolls Ps2 and Ps4) installed in the second mounting section 23. Figure 5(c) is a graph showing the relationship between the amount of yarn Y wound onto the winding bobbins Bw (specifically, winding bobbins Bw1, Bw2, Bw3, Bw4, Bw5, and Bw6) and time (horizontal axis). In all of Figures 5(a) to (c), the origin is the time t0 at which yarn Y begins to be wound onto the winding bobbins Bw1. Furthermore, in this embodiment, for ease of explanation, the amount of yarn (initial amount) of each yarn supply package Ps in the state where yarn Y has not been unwound even once from each yarn supply package Ps is WF. Furthermore, in practice, the formation of multiple yarn feed spools (Ps) can sometimes be interrupted due to yarn breakage or other reasons during the preliminary steps. Therefore, it is important to note that the initial quantities of multiple yarn feed spools (Ps) may not all be the same.

First, at time t0, a yarn supply spool Ps1 is installed in the first mounting section 22. A yarn supply spool Ps2 is installed in the second mounting section 23. The remaining amount of yarn Y in the yarn supply spool Ps1 is W0 (less than the initial amount WF). The remaining amount of yarn Y in the yarn supply spool Ps2 is the initial amount WF. Furthermore, the terminal end of the yarn Y in the yarn supply spool Ps1 and the starting end of the yarn Y in the yarn supply spool Ps2 are knotted together, forming a knotted portion K.

At time t0 (time ts1), the automatic doffing machine 10 completes the installation of the take-up bobbin Bw1 onto the rocker 33 and begins winding the yarn onto the take-up bobbin Bw1. That is, time ts1 is the start time for winding the yarn Y onto the take-up bobbin Bw1. At this time, the yarn Y is unwound from the yarn supply package Ps1. As time passes, the remaining amount of yarn Y in the yarn supply package Ps1 decreases, and the amount of yarn Y wound onto the take-up bobbin Bw1 increases. At time te1, the yarn Y is cut by the cutter of the automatic doffing machine 10, thereby ending the winding process of the yarn Y onto the take-up bobbin Bw1. That is, time te1 is the end of the winding of yarn Y onto the winding bobbin Bw1 (the formation of the winding package Pw1 ends). At this time, the remaining amount of yarn in the supply package Ps1 is W1. Only yarn Y supplied from the supply package Ps1 is wound onto the winding bobbin Bw1. The cutting of yarn Y by the cutter and the attraction of yarn Y by the suction device (i.e., the start of the attraction removal of yarn Y) occur almost simultaneously. And the winding bobbin Bw1 is removed from the rocker 33. Next, after time te1 and then time ts2, the installation of the take-up bobbin Bw2 onto the rocker 33 is completed, and the winding of the yarn Y onto the take-up bobbin Bw2 begins (take-up bobbin replacement operation completed). For example, the moment when the machine control device 5 outputs a command signal for take-up bobbin replacement operation to the automatic doffing machine 10 (i.e., the moment when the take-up bobbin replacement operation begins) is considered the take-up bobbin replacement moment (hereinafter, simply referred to as the replacement moment). The replacement moment is equal to the winding end moment (time te1) of the take-up bobbin Bw (in this case, take-up bobbin Bw1) installed on the rocker 33 before the take-up bobbin replacement operation. Furthermore, the replacement time is approximately equal to the start time (time ts2) of winding of the winding bobbin Bw (or winding bobbin Bw2 in this case) installed on the rocker arm 33 after the winding bobbin replacement operation.

At time ta1, following time ts2, the yarn supply roll Ps1 installed in the first mounting section 22 becomes empty. That is, time ta1 is the unwinding end time when the yarn Y ends unwinding from the yarn supply roll Ps1. At the same time that the yarn supply roll Ps1 becomes empty, at time tb1 (= time ta1), the knotted portion K formed by the knotting of the yarn Y contained in the yarn supply roll Ps1 and the yarn Y contained in the yarn supply roll Ps2 is pulled toward the winding device 19. As a result, the yarn Y is unwound from the yarn supply roll Ps2 installed in the second mounting section 23 for the first time. That is, time tb1 is the start of unwinding of yarn Y from the first unwinding of the yarn supply package Ps2 (yarn Y begins to unwind). Then, at time te2, the winding process of yarn Y onto the take-up bobbin Bw2 (formation of the take-up package Pw2) ends. At this time, the remaining amount of yarn in the yarn supply package Ps2 is W2. Both yarn Y unwound from the yarn supply package Ps1 and yarn Y unwound from the yarn supply package Ps2 are wound onto the take-up bobbin Bw2. In addition, the take-up package Pw2 includes a knotted portion K. Then, at time ts3, the winding process of yarn Y onto the take-up bobbin Bw3 begins. At time te3, when the winding process of yarn Y towards the take-up bobbin Bw3 (formation of the take-up package Pw3) is completed, the remaining amount of the yarn supply package Ps2 is W3. Only the yarn Y supplied from the yarn supply package Ps2 is wound onto the take-up bobbin Bw3.

Furthermore, at time ta1 and before the yarn supply roll Ps2 becomes empty, the yarn supply roll Ps1 is removed from the first mounting section 22 and the yarn supply roll Ps3 is installed into the first mounting section 22 by the bobbin robot 102 (yarn supply roll replacement operation). At this time, the remaining amount of yarn supply roll Ps3 is WF. Then, at an appropriate time, the terminal end of the yarn Y contained in the yarn supply roll Ps2 and the starting end of the yarn Y contained in the yarn supply roll Ps3 are knotted together to form a knotted portion K. Here, for ease of explanation, after the yarn supply roll replacement operation is performed by the bobbin robot 102, the knotting operation is performed by the operator (connection operation). The operator can perform the knotting operation by hand. Alternatively, the operator can perform the knotting operation by manipulating, for example, a portable knotting device (not shown). Alternatively, the bobbin robot 102 can also be equipped with an automatic knotting device (not shown) capable of performing the knotting operation. Thus, the knotting operation can be performed by the bobbin robot 102 without manual intervention.

The following is a brief explanation of the subsequent phenomena. The phenomena related to the winding section 4 are as follows: From time ts4 to time te4, yarn Y is wound onto the winding bobbin Bw4 (forming a winding package Pw4). From time ts5 to time te5, yarn Y is wound onto the winding bobbin Bw5 (forming a winding package Pw5). From time ts6 to time te6, yarn Y is wound onto the winding bobbin Bw6 (forming a winding package Pw6). Furthermore, the phenomena related to the yarn supply section 2 are as follows: At time tb2 (= time ta3) between time ts4 and time te4, the yarn supply package Ps2 becomes empty, and yarn Y begins to unwind from the yarn supply package Ps3. Then, at time tb3, the yarn feed roll Ps2 is replaced with the yarn feed roll Ps4. At time ta4 (= time tb4), between time ts6 and time te6, the yarn feed roll Ps3 becomes empty, and unwinding of yarn Y begins from the yarn feed roll Ps4.

(Summary of basic information obtained by the Information Management Department)

Based on the above phenomena, firstly, referring to Figures 6(a) and (b), a summary of the basic information obtained by the Information Management Department 110 for various judgments and/or calculations will be explained. Figure 6(a) is a table showing the relationship between the individual information of the yarn supply package (described later) and the information at various times, and Figure 6(b) is a table showing the relationship between the individual information of the winding package (described later) and the information at various times.

Information Management Department 110, as basic information, establishes a correlation between each supply coil Ps and obtains individual supply coil information, unwinding start time information, and unwinding end time information (see Figure 6(a)). Furthermore, Information Management Department 110, as basic information, establishes a correlation between each take-up coil Pw and obtains take-up coil information and change time information (see Figure 6(b)). Details regarding the methods for obtaining this information are described below. This information is at least used to establish a correlation between the individual supply coil information of Ps and the individual take-up coil information of Pw.

The individual information of the yarn supply package is identification information applied to each of the multiple yarn supply packages Ps. Each yarn supply package Ps is, for example, attached with an unillustrated ID label representing the individual information of the yarn supply package. The individual information of the yarn supply package is used to identify the yarn supply packages Ps installed in each package mounting section 21. The unwinding start time information is the unwinding start time information mentioned above. The unwinding start time is, for example, tb1, ta3, tb4 mentioned above. The unwinding end time information is the unwinding end time information mentioned above. The unwinding end time is, for example, ta1, tb2, ta4 mentioned above. The individual information of the take-up package is identification information applied to each of the multiple take-up packages Pw. The time slot change information refers to the time slot change information mentioned above. For example, the time slots te1 to te6 mentioned above. As explained later, time slot changes can be processed as both the first and second time slot changes.

(Required Information)

Next, the information management unit 110 will explain the information required to actually obtain individual information on the yarn supply roll, unwinding start time information, unwinding end time information, individual information on the winding roll, and change time information. More specifically, it will explain the information related to the yarn supply roll Ps that is installed and removed relative to the roll mounting unit 21, the information related to the winding roll Pw, and the information obtained by the machine control device 5 during the winding process.

(Information related to the yarn feed rolls transported by the bobbin robot)

The information management unit 110 manages the individual information of the yarn supply rolls Ps delivered by the yarn supply robot 102 and the information associated therewith as follows: First, before or during loading a fully loaded yarn supply roll Ps stored in the yarn supply roll storage unit onto the yarn supply robot 102, the operator inputs the individual information of the yarn supply roll corresponding to that yarn supply roll Ps into the yarn supply control device 102a. For example, the operator can use an ID reader (not shown) electrically connected to the yarn supply control device 102a to read the ID tag attached to each yarn supply roll Ps, thereby inputting the individual information of the yarn supply roll. Alternatively, the operator can operate the bobbin control device 102a based on visually identifiable information displayed on each yarn supply roll Ps, thereby inputting individual information for each yarn supply roll. Alternatively, an ID reader (not shown) can be installed on the bobbin robot 102, which the robot 102 uses to read the aforementioned ID tags.

The information management unit 110 receives individual information about the yarn supply roll Ps from the bobbin control device 102a when the bobbin robot 102 installs the yarn supply roll Ps into the roll mounting unit 21. Then, the information management unit 110 associates the individual information of the yarn supply roll Ps with the individual information of the roll mounting unit 21 to which the yarn supply roll Ps is installed (see Figure 7(a)). The individual information of the roll mounting unit 21 relates to which of the multiple chips 9 the roll mounting unit 21 to which the yarn supply roll Ps is installed belongs, and which of the first mounting unit 22 and the second mounting unit 23 the roll mounting unit 21 is. In this way, the information management department 110 manages the individual information of the yarn supply rolls Ps transported by the bobbin robot 102 in a way that links it to the actions of the bobbin robot 102.

The machine control device 5 acquires yarn supply roll installation time information related to the installation time of the yarn supply roll Ps in the roll mounting section 21 when a new yarn supply roll Ps is installed. The yarn supply roll installation time is, for example, the aforementioned times ta2 and tb3. The machine control device 5 stores the individual information of each yarn supply roll Ps, the individual information of the roll mounting section 21, and the yarn supply roll installation time information in a linked manner (see Figure 7(a)). (In Figure 7(a), the yarn supply roll installation time is simply referred to as the installation time).

After a new yarn feed roll Ps is installed on one of the roll mounting sections 21, the operator knots the beginning of the yarn Y contained in that yarn feed roll Ps with the end of the yarn Y contained in the yarn feed roll Ps installed on the other roll mounting section 21, forming a knotted portion K. The operator then positions the knotted portion K in a predetermined location. Furthermore, the operator inputs information indicating that the knotted portion K is positioned in the predetermined location into the machine control device 5. Based on the input information, the machine control device 5 stores the information indicating that the knotted portion K is positioned in the predetermined location.

(Information related to winding and packaging)

Furthermore, the information management unit 110 manages the individual information of the take-up package Pw as follows. The machine control unit 5 outputs a signal to the automatic doffing machine 10 for changing the take-up bobbin Bw and stores it as a change-up time. For a newly installed take-up bobbin Bw on the rocker 33, this change-up time is approximately equal to the start time of winding the yarn Y into the take-up bobbin Bw. This change-up time is processed as the first change-up time associated with the take-up bobbin Bw (take-up package Pw). In addition, the machine control unit 5 applies individual information (take-up package individual information) to the take-up package Pw when the winding process of the yarn Y into the take-up bobbin Bw is completed (when the formation of the take-up package Pw is completed). 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 spindle 9 as the individual information of the winding package Pw. Furthermore, the machine control device 5 stores the time when a signal for removing the winding package Pw from the winding device 19 is output to the automatic doffing machine 10 as the second replacement time. The body control device 5 stores the body number and the identification number information of the spindle 9 in association with the information on the first replacement time (first replacement time information) and the second replacement time information (second replacement time information). Both the first replacement time information and the second replacement time information are included in the replacement time information. Furthermore, the machine control device 5 can also obtain a prescribed management number in association with this information and assign it as individual winding package information to each winding package Pw. For example, as shown in Figure 6(b), when the aforementioned “Pw1” to “Pw6” are used as management numbers (individual winding package information), the management number is associated with the first changeover time and the second changeover time (furthermore, the machine number and the identification number of the tablet 9 are omitted from the illustration). The machine control device 5 prints this information on a label not shown. This label can be affixed to the winding spool Bw by the operator.

Furthermore, as another mechanism for obtaining individual information about the take-up package, an ID label (not shown) can be pre-attached to an empty take-up bobbin Bw. This allows individual take-up package information to be pre-applied to the take-up bobbin Bw before take-up processing. The automatic doffing machine 10 can also have an ID reader (not shown). For example, when the automatic doffing machine 10 installs a take-up bobbin Bw onto the take-up device 19, or removes a take-up package Pw from the take-up device 19, the aforementioned ID reader can read the ID label attached to that take-up bobbin Bw, thereby sending the individual information of that take-up bobbin Bw to the machine control device 5. Alternatively, instead of the automatic doffing machine 10, an operator can read the ID label using an ID reader (not shown). Alternatively, instead of reading the ID tag using an ID reader, the operator can manually input the individual information of the winding bobbin Bw into the machine control device 5.

As mentioned above, the replacement time information includes both the first replacement time information and the second replacement time information. Specifically, consider time te1. Time te1 is the time when the machine control device 5 outputs an instruction signal to begin the replacement operation of the take-up bobbin Bw1 (take-up package Pw1) after the end of the take-up process of the yarn Y, and the new take-up bobbin Bw2 (take-up package Pw2). Time te1 is equal to the take-up end time of take-up package Pw1 and approximately equal to the take-up start time of take-up package Pw2. Therefore, as shown in Figure 6(b), the information management unit 110 processes the information of time te1 as the first replacement time information and establishes a correlation between the first replacement time information and the take-up package individual information of take-up package Pw2. That is, time te1 is processed as the first changeover time related to the winding package Pw2. Furthermore, the information management unit 110 processes the information of time te1 as second changeover time information, and establishes a correlation between the second changeover time information and the individual winding package information of the winding package Pw1. In this case, time te1 is processed as the second changeover time related to the winding package Pw1. The same first and second changeover time information is obtained in other winding packages Pw.

The first changeover time associated with a specific take-up bobbin Bw (take-up package Pw) can be used as the take-up bobbin installation time when the take-up bobbin Bw is installed on the rocker arm 33. The second changeover time associated with a specific take-up bobbin Bw (take-up package Pw) can be used as the take-up bobbin removal time when the take-up bobbin Bw is removed from the rocker arm 33. In other words, the first changeover time information can be used as take-up start time information associated with the take-up start time of the take-up bobbin Bw. The second changeover time information can be used as take-up end time information associated with the take-up end time of the take-up bobbin Bw. Information Management Department 110 may also process the first changeover time information directly as the scroll start time information, and the second changeover time information directly as the scroll end time information. Alternatively, Information Management Department 110 may perform prescribed calculations on the changeover times to obtain more accurate scroll start time and/or scroll end time information.

(Information acquired by the machine control unit during the winding process)

Next, the information acquired by the machine control device 5 during the winding process of the yarn Y-axis take-up bobbin Bw will be explained. This information is used to obtain, in conjunction with the information shown in FIG7(a), individual yarn supply package information, unwinding start time information, and unwinding end time information in a related manner.

Based on the detection results of the filament detection sensor 24, the machine control device 5 determines whether a filament supply roll Ps has been switched, indicating a filament supply roll switch. For example, referring to Figures 5(a) and (b), a filament supply roll switch occurs when the filament supply roll Ps1 becomes empty and the filament Y is first unwound from the filament supply roll Ps2. When the state of the filament detection sensor 24 changes from detecting the filament Y by one of the first detection unit 25 and the second detection unit 26 to detecting the filament Y by the other of the first detection unit 25 and the second detection unit 26, the machine control device 5 determines that a filament supply roll switch has occurred. When the machine control device 5 determines that a yarn feed roll change has occurred, it acquires and stores the following information shown in the table of FIG7(b). The machine control device 5 stores the individual information of the roll mounting section 21 that starts supplying yarn Y when a yarn feed roll change occurs (either the first mounting section 22 or the second mounting section 23), and the time when the yarn feed roll change occurs, in association with the time when the yarn feed roll change occurs. Regarding the roll mounting section 21 that starts supplying yarn Y, the time when the yarn feed roll change occurs is treated as the unwinding start time. Furthermore, the machine control device 5 stores the individual information of the winding mounting unit 21, which indicates the end of yarn Y supply when a yarn supply winding change occurs, in association with the moment the yarn supply winding change occurs. Regarding the winding mounting unit 21, which indicates the end of yarn Y supply, the moment of the yarn supply winding change is treated as the unwinding end time.

(Methods for obtaining the start and end times of the backloop)

Next, referring to Figures 5(a), (b), 7(a), (b), and 8, the method for obtaining unwinding start time and unwinding end time information based on the information obtained by the machine control device 5 will be explained. Figure 8 is a table showing the relationship between individual yarn supply roll information, roll mounting section, and various times.

The machine control device 5 uses the yarn feed roll installation time information and the yarn feed roll switching information to obtain the unwinding start time information and unwinding end time information according to the following steps. As a specific example, when obtaining the unwinding start time and unwinding end time of the yarn feed roll Ps3, the machine control device 5 obtains the individual information (first installation section 22) of the roll installation section 21 on which the yarn feed roll Ps3 is installed and the yarn feed roll installation time (time ta2) based on the yarn feed roll installation time information. Next, the machine control device 5 obtains information about the earliest unwinding start time (time ta3, see Figures 5(a) and (b)) of the unwinding start time of the yarn supply roll Ps installed in the first mounting section 22, which is later than time ta2, and uses this information as the unwinding start time of the yarn supply roll Ps3. Furthermore, the machine control device 5 obtains information about the unwinding end time (time ta4) associated with this unwinding start time, and uses this information as the unwinding end time of the yarn supply roll Ps3. Thus, the individual information of the yarn supply roll Ps is obtained in a linked manner with the unwinding start time information and the unwinding end time information. In other words, by linking the yarn supply roll installation time information of a certain yarn supply roll Ps with the earliest yarn supply roll switching time information after the yarn supply roll installation time, the unwinding start time information and unwinding end time information of that yarn supply roll Ps can be obtained (see Figure 8). This information can be obtained for each yarn supply roll Ps, not just the yarn supply roll Ps3.

As described above, the machine control device 5 obtains the unwinding start time and unwinding end time information. Furthermore, the machine control device 5 can obtain the unwinding start time and unwinding end time information at any given time. For example, the machine control device 5 can also obtain the unwinding start time and/or unwinding end time information at a time when a yarn feed roll change occurs. Alternatively, the machine control device 5 can also obtain the unwinding start time and/or unwinding end time information using previously obtained yarn feed roll installation time information and yarn feed roll change information when an operator performs an operation at any time. Additionally, the management device 101 can also obtain the unwinding start time and/or unwinding end time information.

(Establishing a relationship between individual information on the winding package and the individual information on the supply package)

Next, the method for establishing the association between the individual winding package information and the individual supply package information will be explained. For the specific association between the individual winding package information and the individual supply package information, please refer to the table shown in Figure 9. In the following method, for example, the management device 101 obtains the associated information, but it is not limited to this. That is, the machine control device 5 may also obtain this information.

As related specific examples, the first and second specific examples will be explained below. As the first specific example, when the management device 101 obtains individual information about the yarn supply package Ps that supplies yarn Y to the winding bobbin Bw3 (winding package Pw3), it first obtains information about the first changeover time (time te2) and the second changeover time (time te3) related to the winding bobbin Bw3 (winding package Pw3). The first changeover time can be processed as the winding bobbin installation time or the winding start time. The second changeover time can be processed as the winding bobbin removal time or the winding end time. Next, the management device 101 associates the individual information of the supply rolls Ps (supply rolls Ps2, refer to Figure 6(b)) that are associated with the latest unwinding start time (time tb1, see Figure 5(b)) preceding time te2 with the individual information of the take-up roll Pw3. In other words, the management device 101 determines the individual information of the supply rolls Ps that are associated with the latest unwinding start time preceding the take-up start time among the individual information of multiple supply rolls Ps. Then, the management device 101 associates the determined individual information of the supply rolls Ps with the individual information of the take-up roll Pw that is associated with that take-up start time. Furthermore, the management device 101 determines whether a yarn supply roll change occurred between time te2 and time te3. In this example, there is no time when a yarn supply roll change occurs between time te2 and time te3 (i.e., the unwinding start time). Therefore, the management device 101 determines that no yarn supply roll change occurred between time te2 and time te3. Thus, information is obtained that only yarn Y from the yarn supply roll Ps2 is supplied to the take-up roll Pw3 (see Figure 9).

As a second specific example, when the management device 101 obtains individual information about the yarn supply package Ps that supplies yarn Y to the winding bobbin Bw4 (winding package Pw4), it first obtains information about the first change time (time te3) and the second change time (time te4) of the winding bobbin Bw4 (winding package Pw4). Next, the management device 101 associates the individual information of the yarn supply package Ps (yarn supply package Ps2, see Figure 6(b)) that is associated with the latest unwinding start time (time tb1, see Figure 5(b)) which is earlier than time te3 with the individual information of the winding package Pw4. Furthermore, the management device 101 determines whether a feed roll change occurred between time te3 and time te4. In this example, there is a time (i.e., the unwinding start time) between time te3 and time te4 where a feed roll change occurs (time ta3). Therefore, the management device 101 determines that a feed roll change occurred between time te3 and time te4. Based on this determination, the management device 101 associates the individual information of the feed roll Ps (feed roll Ps3, see Figure 6(b)) associated with time ta3 with the individual information of the winding roll Pw4. In other words, the management device 101 associates the individual information of multiple yarn supply packages Ps with the unwinding start time between the first and second change times, and with the individual information of the take-up package Pw associated with the first change time. Thus, it obtains information that yarn Y was supplied from yarn supply packages Ps2 and Ps3 to the take-up package Pw3 (see Figure 9).

(Determining whether a knot is present or not)

Furthermore, the management device 101 makes the following determination based on whether the aforementioned yarn feed roll change has occurred. For example, if the management device 101 determines that no yarn feed roll change has occurred from the first changeover time (time te2) to the second changeover time (time te3) related to the take-up bobbin Bw3 (take-up roll Pw3), it determines that the take-up roll Pw3 does not contain the knotted portion K (see FIG. 9). Furthermore, if the management device 101 determines that a yarn feed roll change has occurred from the first changeover time (time te3) to the second changeover time (time te4) related to the take-up bobbin Bw4 (take-up roll Pw4), it determines that the take-up roll Pw4 contains the knotted portion K (see FIG. 9).

Furthermore, the management device 101 infers the location of the knotted portion K in the take-up package Pw by performing the following calculations. As a simple example, the management device 101 calculates the ratio of the time from time te3 to the time at which the yarn package is switched (time ta3) to the time from the first changeover time (time te3) to the second changeover time (time te4) associated with the take-up bobbin Bw4 (take-up package Pw4). That is, it calculates the ratio of ta3-te3 to te4-te3. When this value is set to, for example, N percent, it can be inferred that when N percent of the yarn Y is wound onto the take-up bobbin Bw4, the knotted portion K is mixed into the take-up package Pw4.

(Chart output)

In addition, the Information Management Unit 110 outputs the charts described below. The Information Management Unit 110 uses individual information on the yarn supply package Ps, unwinding start time information, individual information on the winding package Pw, and changeover time information to create chart data representing the unwinding period for each yarn supply package Ps and the winding period for each winding package Pw. The unwinding period is the time from the start of unwinding yarn Y from the yarn supply package Ps to the end of unwinding. The winding period is the time from the start of winding yarn Y onto the winding bobbin Bw to the end of winding. The information management unit 110 displays (outputs) the charts shown in Figures 5(a) to (c) the management output unit 101b (display) of the management device 101 based on the generated chart data. The management device 101 is equivalent to the output control unit of the present invention. The management output unit 101b is equivalent to the output unit of the present invention. The type of chart is not limited to the above, as long as the output chart allows the operator to visually confirm the unwinding period of each feed roll Ps and the winding period of each take-up roll Pw. Thus, the operator can easily establish a correlation between the individual feed roll information and the individual take-up roll information. In addition to the information shown in Figures 5(a) to (c), the chart can also represent more detailed information. For example, the individual information of the feed packages Ps associated with a specific take-up package Pw can be displayed simultaneously with the individual information of that take-up package Pw. Furthermore, information indicating which layer of yarn Y contained in the feed package Ps was supplied with yarn Y to that specific take-up package Pw can be displayed along with the individual feed package information. Additionally, if the management output unit 101b includes a printer, the information management unit 110 can also be a printer that prints charts. Alternatively, the information management unit 110 can output (display) charts to the machine output unit 5b of the machine control device 5. Alternatively, the output control unit for creating chart data and the output unit for outputting charts can be provided separately from the information management unit 110.

As mentioned above, the Information Management Department 110 can determine the unwinding start time of each yarn supply package Ps. Furthermore, by obtaining the changeover time information, the winding start and end times can be determined for each take-up package Pw. Thus, various information regarding the relationship between the take-up bobbin Bw (take-up package Pw) and the yarn supply packages Ps can be obtained. For example, it can be determined which layer of yarn Y from the yarn supply packages Ps forms a particular take-up package Pw. Furthermore, it can be determined whether a knotted portion K is mixed into the take-up package Pw. In this case, it can be further determined where the knotted portion K is mixed into the take-up package Pw. In this way, various useful information can be extracted.

Furthermore, by utilizing the unwinding start time and change time information, it is easy to identify situations where knotted portions (K) are mixed into the winding package (Pw).

Furthermore, by calculating the first changeover time, the second changeover time, and the unwinding start time, the location of the knotted portion K in the take-up roll Pw can be easily determined.

Furthermore, individual information about the yarn supply package and the unwinding start time are obtained in a correlated manner. Therefore, by considering the sequential relationship between each moment, it is possible to determine from which yarn supply package Ps supplied yarn Y to a particular winding bobbin Bw.

Furthermore, operators can easily correlate individual winding package information with individual yarn supply package information simply by observing the output charts.

Furthermore, it can automatically establish a correlation between the individual information of a specified take-up package Pw and the individual information of the supply package Ps that supplies the yarn Y when the yarn begins to be wound into the specified take-up package Pw.

Furthermore, when yarn Y is sequentially supplied to a take-up bobbin Bw from multiple yarn supply packages Ps, it is possible to automatically establish a correlation between all individual information of the multiple yarn supply packages Ps and the individual information of the specific take-up package Pw.

Furthermore, when the yarn supply rolls Ps are installed into the roll mounting unit 21 by the bobbin robot 102, individual information of the yarn supply rolls can be automatically linked to the roll mounting unit 21.

Furthermore, the yarn detection sensor 24 can constantly identify which of the multiple yarn feed sections 21 is receiving yarn. This allows for automatic and accurate correlation between individual yarn feed roll information and unwinding start time information.

Next, variations derived from the above embodiments will be described. However, for parts having the same structure as the above embodiments, the same symbols will be applied and their descriptions will be appropriately omitted.

(1) In the above embodiment, whether the yarn supply package switching occurs is determined based on the detection result of the yarn detection sensor 24 having the first detection part 25 and the second detection part 26, but the invention is not limited to this. For example, as shown in FIG. 10 , the yarn supply part 2a of the false twisting machine 1a may be provided in each spindle 9a. The switching detection part 41 has a different structure from the yarn detection sensor 24. The switching detection unit 41 may include a supply sensor 42 and a knotted portion sensor 43, for example. The supply sensor 42 is configured to detect whether the yarn Y is being supplied from the first attachment part 22 . The knotted portion sensor 43 is configured to detect the knotted portion K that is stationary and arranged at a predetermined position. In the above configuration, when the knotted portion K moves from a predetermined position and is no longer detected by the knotted portion sensor 43, it can be determined that a feed roll change has occurred. Furthermore, it is possible to determine, based on the detection result of the feed sensor 42, which of the first mounting section 22 and the second mounting section 23 is being fed the yarn Y during the feed roll change. Thus, even when using the detection result of the knotted portion K, it is reliably possible to determine which of the first mounting section 22 and the second mounting section 23 is being fed the yarn Y. Additionally, the knotted portion sensor 43 can also be configured to detect the moving knotted portion K.

(2) In the embodiments described above, the information management unit 110 determines whether a yarn supply roll change has occurred based on the detection results of the yarn detection sensor 24 or the switching detection unit 41, but is not limited to this.

(3) In the embodiments described above, the information management unit 110 obtains the unwinding start time information and unwinding end time information based on the yarn supply roll installation time information and the yarn supply roll switching time information. That is, the information management unit 110 establishes a correlation between the yarn supply roll installation time and the unwinding start time. However, it is not limited to this. The information management unit 110 may also establish a correlation between the individual information of the roll installation unit 21 that starts supplying yarn Y, the individual information of the yarn supply roll Ps installed by the roll installation unit 21, and the unwinding start time (i.e., switching time) of the yarn supply roll installation unit 21 when a yarn supply roll switching occurs. In this way, the unwinding start time information can also be obtained. In this situation, the information management unit 110 may not necessarily obtain information about the timing of the yarn supply reel installation. That is, the information management unit 110 may obtain information by associating the individual information of the yarn supply reel Ps with the individual information of the reel installation unit 21 only when the yarn supply reel Ps is installed in the yarn supply reel holding unit 20.

(4) In the embodiments described above, the information management unit 110 obtains various related and/or various information based on the winding start time information, winding end time information, unwinding start time information, and unwinding end time information, but is not limited thereto. That is, the information management unit 110 may also obtain information related only to the yarn supply package individual information, the unwinding start time information, and the unwinding end time information, and obtain information related to the winding package individual information and the replacement time information. Using this information, various useful information can also be obtained through another computer device (not shown).

(5) In the embodiments described above, the information management unit 110 obtains unwinding completion information, but is not limited to this. That is, the unwinding start time of a certain yarn supply roll Ps is the unwinding completion time of the yarn supply roll Ps that has been supplied with yarn Y from the point where the yarn supply roll Ps began to unwind yarn Y. Based on this fact, the unwinding start time information of a certain yarn supply roll Ps (e.g., yarn supply roll Ps2) can also be used as the unwinding completion information of another yarn supply roll Ps (e.g., yarn supply roll Ps1). However, in the above configuration, the various judgment and/or calculation steps become complicated. Therefore, to simplify various judgments and/or calculations, it is recommended that the Information Management Department obtain the unwinding end information via 110.

(6) In the embodiments described above, the yarn feed roll replacement operation is performed by the bobbin robot 102. Furthermore, the take-up bobbin replacement operation is performed by the automatic doffing machine 10. However, this is not a limitation. The yarn feed roll replacement operation can also be performed by an operator. Required information, such as individual yarn feed roll information, can also be input by the operator, for example, into the machine control device 5. The take-up bobbin Bw installation and removal operation can also be performed by an operator. Required information, such as individual take-up roll information, can also be input by the operator, for example, into the machine control device 5.

(7) In the embodiments described above, the information management unit 110 establishes a connection between each supply roll Ps and obtains individual supply roll information and unwinding start time information, but is not limited to this. The information management unit 110 may not necessarily establish a connection between individual supply roll information and unwinding start time information. For example, the information management unit 110 may not obtain individual supply roll information, but only obtain unwinding start time information for each supply roll Ps. Even if this is done, by utilizing the unwinding start time information and change time information, various useful information can be obtained, such as information on whether the winding roll Pw contains a knotted portion K.

(8) In the embodiments described above, the machine control device 5 acquires information on the timing of the output signal used to cause the automatic doffing machine 10 to perform a take-up bobbin changing operation, as changing time information. However, it is not limited to this. For example, the machine control device 5 may also be configured to detect and/or determine the completion of the take-up bobbin changing operation. Then, the machine control device 5 may also acquire information on the timing of the completion of the take-up bobbin changing operation, as changing time information.

(9) In the embodiments described above, the information management unit 110 has multiple machine control devices 5 and management devices 101, but is not limited thereto. That is, the information management unit 110 may also include a computer device (not shown) other than the machine control devices 5 and management devices 101. Alternatively, the information management unit 110 may only have the machine control devices 5 or the management devices 101. That is, either the machine control devices 5 or the management devices 101 may obtain the necessary information.

(10) In the above embodiments, the yarn processing equipment 100 includes a plurality of false twisting machines 1, but the invention is not limited to this. The yarn processing equipment 100 may include only one false twisting machine 1 . In addition, the management device 101 does not need to be provided. In this case, the false twist processing machine 1 corresponds to the yarn processing equipment of the present invention. Furthermore, the false twisting machine 1 has a plurality of spindles 9, but is not limited to this. That is, the number of spindles 9 provided in the false twisting machine 1 may be one. In other words, the number of the yarn supply package holding parts 20 provided in the yarn supply part 2 may be one.

(11) The present invention can be applied to other yarn processing equipment including a yarn processing machine instead of the yarn processing equipment 100 including the false twisting machine 1 . For example, the present invention can also be applied to a yarn processing equipment including an air flow processing machine (yarn processing machine) described in Japanese Patent Application Laid-Open No. 2002-088605.
