[0003] [Patent Document 1] Patent Publication No. 2021-024741 Summary of the Invention [Problem to be solved by the invention]

[0004] In general, in manufacturing plants equipped with yarn processing equipment and producing processed yarn, inventory valuation is performed as needed. The asset value of unprocessed yarn, which is a current asset, is also evaluated. For this purpose, it is necessary to consider not only the total amount of yarn contained in each of multiple yarn supply packages before use, but also the individual remaining amounts of yarn contained in multiple yarn supply packages from which yarn is unwound (i.e., currently in use) and / or their total value (total remaining amount). However, in conventional equipment, to obtain information on the remaining amount of yarn in each of multiple yarn supply packages currently in use (multiple unwound packages), an operator must first visually inspect each unwound package one by one. Under these circumstances, with the recent trend toward increasingly mass production, it is difficult to simultaneously determine the remaining amounts of yarn in multiple unwound packages. Therefore, it is extremely difficult to appropriately obtain information on the total remaining amount. Furthermore, obtaining information on the total remaining amount may place a heavy burden on the operator.

[0005] The object of the present invention is to make it possible to easily obtain information on the individual and / or total remaining amounts of yarn contained in multiple unwinding packages used in a manufacturing factory, and to reduce the burden on operators in obtaining information on the individual and / or total remaining amounts. [Means for solving the problem]

[0006] A yarn processing equipment according to a first aspect of the present invention is a yarn processing machine having a plurality of processing spindles, each of which is configured to process a yarn unwound from a yarn supply package and wind it onto a winding bobbin to form a winding package; an information management unit configured to manage information related to the yarn processing machine; and an output unit configured to output the information, wherein the information management unit is configured to manage a predetermined number of yarns as the yarn supply package for each of the plurality of processing spindles. Yarn feeding The yarn contained in the unwinding package in which the yarn is being unwound at the information reference time or in which the yarn has been unwound at the yarn feeding information reference time At the yarn feeding information reference timeAn individual remaining amount information acquisition process is performed to acquire individual remaining amount information that takes into account individual remaining amounts indicating remaining amounts, and / or a total remaining amount information acquisition process is performed to acquire total remaining amount information that takes into account a total remaining amount obtained by adding up the individual remaining amounts related to the multiple machined spindles, and the individual remaining amount information for each of the multiple machined spindles acquired by the individual remaining amount information acquisition process is So that the operator can get The individual remaining amount information output process and / or the total remaining amount information acquired by the total remaining amount information acquisition process are output to the output unit. The operator can obtain The total remaining amount information output process is performed to be output to the output unit.

[0007] The "individual remaining amount content information" may be information on the individual remaining amount itself, or may be information obtained by adding another value to the individual remaining amount. The "total remaining amount content information" may be information on the total remaining amount itself, or may be information obtained by adding another value to the total remaining amount. In the present invention, the output unit outputs the individual remaining amount content information and / or the total remaining amount content information for each of the multiple processing spindles. When the individual remaining amount content information is output, the operator can check the individual remaining amounts for the multiple unwinding packages at a glance. Based on the individual remaining amounts checked at a glance in this manner, the total remaining amount can be obtained by adding up the individual remaining amounts for the multiple unwinding packages. Furthermore, when the total remaining amount content information is output, the total remaining amount can be known in a short time. Therefore, information on the individual remaining amounts and / or the total remaining amounts of yarn contained in the multiple unwinding packages used in the manufacturing factory can be easily obtained, and the burden on the operator in obtaining the individual remaining amounts and / or the total remaining amounts can be reduced.

[0008] The yarn processing equipment of a second invention is the yarn processing equipment of the first invention, characterized in that the information management unit performs the total remaining amount information acquisition process and the total remaining amount information acquisition process.

[0013] In the present invention, since the currently unwinding package and the spare package are attached to the respective supplying yarn package holders, it is also necessary to know the remaining amount of yarn contained in the spare package. Even in such a configuration, since it is possible to output information on at least the individual remaining amount and / or information on the total remaining amount, the burden on the operator can be reduced.

[0014] The yarn processing equipment of a fifth invention is the yarn processing equipment of the fourth invention, characterized in that the information management unit is configured to allow an operator to input spare remaining amount related information regarding a spare remaining amount, which is the remaining amount of yarn contained in the spare package held in the yarn supply package holding unit, and is configured to be able to acquire the individual remaining amount content information for each of the plurality of processing spindles, taking into account the spare remaining amount related information.

[0015] In the present invention, although the operator needs to check the spare remaining amount related information and input it into the information management unit, when such input is performed, the individual remaining amount content information that takes the spare remaining amount related information into consideration can be obtained, thereby reducing the burden on the operator to some extent.

[0016] The yarn processing equipment of a sixth aspect of the present invention is the yarn processing equipment of the fourth or fifth aspect of the present invention, wherein each of the plurality of processing spindles includes an attachment information acquisition unit configured to be able to acquire attachment information, which is information on whether the spare package is attached to the yarn supply package holding unit, and the information management unit is configured to be able to acquire the individual remaining amount content information for each of the plurality of processing spindles based on the attachment information and taking into account spare remaining amount related information on a spare remaining amount, which is the remaining amount of yarn contained in the spare package.

[0031] (Outline of yarn processing equipment) Next, an embodiment of the present invention will be described. A schematic diagram of a yarn processing equipment 100 according to this embodiment will be described with reference to the block diagram of FIG. 1. As shown in FIG. 1, the yarn processing equipment 100 includes a plurality of false twisting machines 1 (yarn processing machines of the present invention) and a management device 101. The plurality of false twisting machines 1 are arranged, for example, along a predetermined machine frame longitudinal direction (see FIG. 2, etc.). Each false twisting machine 1 is configured to false twist a yarn Y (see FIG. 2, etc.) made of synthetic fibers such as polyester and nylon (polyamide-based fibers). The yarn Y is, for example, a multifilament yarn made of multiple filaments (not shown). As will be described later, each false twisting machine 1 is configured to process the yarn Y supplied from a yarn supplying unit 2 using a processing unit 3 and wind the yarn Y onto a winding bobbin Bw attached to a winding unit 4 to form a winding package Pw. Each false twisting machine 1 is controlled by a machine frame control device 5, which is a computer device provided in each false twisting machine 1.

[0032] The management device 101 is a host computer for comprehensively managing information acquired by multiple machine control devices 5. The management device 101 has a management input unit 101a (e.g., a mouse and keyboard), a management output unit 101b (e.g., a display), and a management storage unit 101c (e.g., a hard disk). The management device 101 and the multiple machine control devices 5 together constitute the information management unit 110 of this embodiment. Details of the information handled by the information management unit 110 will be described later.

[0033] (Overall configuration of false twisting machine) Next, the overall configuration of the false twisting machine 1 will be described with reference to Figures 2 and 3. Figure 2 is a side view of the false twisting machine 1. Figure 3 is a schematic diagram of the false twisting machine 1 unfolded along the path (yarn path) of the yarn Y. The direction perpendicular to the plane of the paper in Figure 2 is the longitudinal direction of the machine base, and the left-to-right direction of the paper is the width direction of the machine base. The direction perpendicular to both the longitudinal direction and the width direction of the machine base is the up-down direction (vertical direction) in which gravity acts. The direction in which the yarn Y runs is the yarn running direction. The false twisting machine 1 includes a yarn supplying unit 2 for supplying multiple yarns Y, a processing unit 3 for processing (false-twisting) the multiple yarns Y supplied from the yarn supplying unit 2, a winding unit 4 for winding the multiple yarns Y processed by the processing unit 3 onto a winding bobbin Bw, and a machine control device 5.

[0034] The yarn supplying unit 2 has a creel stand 6 that holds multiple yarn supply packages Ps and is configured to be able to simultaneously supply multiple yarns Y to the processing unit 3. The processing unit 3 is configured to unwind and process multiple yarns Y from the yarn supplying unit 2. The processing unit 3 is configured to, in order from the upstream side in the yarn running direction, include a first feed roller 11, a twist stop guide 12, a first heating device 13, a cooling device 14, a false twist device 15, a second feed roller 16, a second heating device 17, and a third feed roller 18. These components of the processing unit 3 are provided, for example, on each of multiple spindles 9 (see FIG. 3 ), which will be described later. The winding unit 4 has multiple winding devices 19. Each winding device 19 winds the yarn Y that has been false twisted in the processing unit 3 onto a winding bobbin Bw to form a winding package Pw. The winding section 4 is also provided with a plurality of auto doffers 10 corresponding to the plurality of winding devices 19, respectively, for replacing the formed winding package Pw with a new empty winding bobbin Bw.

[0035] The machine control device 5 controls each component of the yarn supplying unit 2, the processing unit 3, and the winding unit 4. The machine control device 5 is, for example, a general computer device. The machine control device 5 has a machine input unit 5a, a machine output unit 5b (the output unit of the present invention), and a machine memory unit 5c (see FIG. 1). The machine input unit 5a has, for example, a mouse, a touch panel, and / or a keyboard (not shown), and is configured to be operable by an operator. The machine output unit 5b has, for example, a known display 5b1 and a known printer 5b2, and is configured to be able to output information. The machine memory unit 5c is configured to store various information for controlling the components of the yarn supplying unit 2, the processing unit 3, and the winding unit 4. The machine control device 5 controls the components of the yarn supplying unit 2, the processing unit 3, and the winding unit 4 based on the various information. Alternatively, the machine control device 5 may indirectly control these components via various control devices (not shown) for controlling the components of the yarn supplying unit 2, the processing unit 3, and the winding unit 4. A management device 101, which is a host computer, is electrically connected to the main control device 5. The management device 101 is capable of making various decisions and / or calculations, which will be described later, using information acquired by the main control device 5.

[0036] Each of the multiple false twisting machines 1 has a main frame 7 and a winding table 8 spaced apart in the width direction of the machine. The main frame 7 and the winding table 8 are arranged to extend over approximately the same length in the longitudinal direction of the machine. The main frame 7 and the winding table 8 are arranged to face each other in the width direction of the machine. The false twisting machine 1 has a unit called a span, which includes a pair of the main frame 7 and the winding table 8. In one span, various devices are arranged so that multiple yarns Y running side by side in the longitudinal direction of the machine can be false twisted simultaneously. The spans of the false twisting machines 1 are arranged symmetrically on the left and right sides of the drawing, with the center line C of the main frame 7 in the width direction as the axis of symmetry (the main frame 7 is common to both spans). The multiple spans are also arranged in the longitudinal direction of the machine. In FIG. 2, a false twisting machine 1A is depicted as one of the multiple false twisting machines 1, on the right side of the center line C. In addition, in FIG. 2, a false twisting machine 1B, which is separate from the false twisting machine 1A, is depicted on the left side of the center line C on the paper.

[0037] Furthermore, a group of components through which a single yarn Y passes after being supplied from the yarn supplying section 2 until it reaches the winding section 4 is called a "spindle." In other words, each of the multiple false twisting machines 1 has the same number of spindles 9 (processing spindles of the present invention; see FIG. 3) as the number of winding devices 19 that each false twisting machine 1 has. As an example, two spindles 9 (spindles 9A and 9B) are shown in FIG. 3. Roughly speaking, the multiple spindles 9 are arranged side by side along the longitudinal direction of the machine frame. In an inclusive relationship, the false twisting machine 1 has multiple spans, and each span has multiple spindles 9. The false twisting machine 1 can false twist the yarn Y using the spindles 9 on which the yarn Y is hung.

[0038] (Yarn feeding section) The configuration of the yarn supplying unit 2 will be described with reference to FIGS. 2 and 3. The creel stand 6 of the yarn supplying unit 2 has a plurality of yarn supply package holding units 20 (see FIG. 3) provided corresponding to the plurality of spindles 9, respectively. Each of the plurality of yarn supply package holding units 20 is configured to allow two yarn supply packages Ps to be attached and detached. That is, the yarn supply package holding unit 20 has two package attachment units 21. For convenience of explanation, one of the two package attachment units 21 will be referred to as a first attachment unit 22, and the other will be referred to as a second attachment unit 23. The first attachment unit 22 and the second attachment unit 23 are each configured to allow one yarn supply package Ps to be attached and detached. The attachment and detachment of the yarn supply package Ps to and from the package attachment unit 21 is performed, for example, by an operator.

[0039] Each yarn supply package holding unit 20 of the yarn supply unit 2 is configured to be able to supply the yarn Y without interruption as follows. For example, as shown in FIG. 3 , a yarn supply package PsA, which is any one of the multiple yarn supply packages Ps, is attached to the first attachment unit 22. A yarn supply package PsB, which is different from the yarn supply package PsA, is attached to the second attachment unit 23. When the yarn Y is being unwound from the yarn supply package PsA, the yarn supply package PsA corresponds to the currently unwound package of the present invention. At this time, the yarn supply package PsB corresponds to the spare package of the present invention. The end of the yarn Y contained in the yarn supply package PsA and the beginning of the yarn Y contained in the yarn supply package PsB are knotted (connected). This forms a knot portion K (yarn connection portion) between the two yarns Y. In this case, after the yarn supply package PsA becomes empty, the yarn Y can be supplied without interruption from the yarn supply package PsB. Specifically, immediately after the supply of the yarn Y from the yarn supply package PsA is completed and the yarn supply package PsA becomes empty, the knot K is pulled downstream in the yarn running direction (toward the winding device 19), causing the yarn Y to be unwound from the yarn supply package PsB. That is, after the yarn Y has been unwound from the yarn supply package Ps attached to one package attachment unit 21, the yarn Y begins to be unwound from the next yarn supply package Ps attached to the other package attachment unit 21. Hereinafter, for convenience of explanation, this event is referred to as yarn supply package switching. This allows the yarn Y to be supplied without interruption. After that, the empty yarn supply package Ps (yarn supply bobbin Bs) is replaced with a new yarn supply package Ps, for example, by an operator.

[0040] A yarn detection sensor 24 is disposed downstream of each yarn supply package holder 20 in the yarn running direction. The yarn detection sensor 24 is configured to detect whether the yarn Y is supplied from the first attachment portion 22 or the second attachment portion 23. As shown in FIG. 3 , the yarn detection sensor 24 has a first detection portion 25 and a second detection portion 26. The first detection portion 25 is configured to detect whether the yarn Y is supplied from the first attachment portion 22. The second detection portion 26 is configured to detect whether the yarn Y is supplied from the second attachment portion 23. The first detection portion 25 and the second detection portion 26 are, for example, optical sensors that optically detect the yarn Y. For more details about the yarn detection sensor 24, see, for example, Japanese Patent No. 5873105. Alternatively, the first detection portion 25 and the second detection portion 26 may be, for example, contact-type sensors.

[0041] (Processing department) The configuration of the processing unit 3 will be described with reference to Figures 2 and 3. In the following, only a portion of the processing unit 3 that corresponds to one weight 9 will be described.

[0042] The first feed roller 11 is configured to unwind the yarn Y from the yarn supply package Ps attached to the yarn supplying section 2 and feed the yarn Y to the first heating device 13. The first feed roller 11 is disposed upstream of the twist stop guide 12 in the yarn running direction. The conveyance speed of the yarn Y by the first feed roller 11 is substantially equal to the unwinding speed Vu (see FIG. 3 ) at which the yarn Y is unwound from the yarn supply package Ps. Information about the set value of the conveyance speed of the yarn Y by the first feed roller 11 is stored in advance in, for example, the machine control device 5. A cutter (not shown) may be provided upstream of the first feed roller 11 in the yarn running direction. When a yarn breakage occurs, the cutter cuts the yarn Y, thereby preventing the yarn Y from winding around rotationally driven components such as the first feed roller 11.

[0043] The twist stop guide 12 is configured to prevent the twist imparted to the yarn Y by the false twist device 15 from propagating upstream in the yarn running direction of the twist stop guide 12. The twist stop guide 12 is disposed downstream in the yarn running direction of the first feed roller 11 and upstream in the yarn running direction of the first heating device 13.

[0044] The first heating device 13 is configured to heat the yarn Y fed from the first feed roller 11. The first heating device 13 is disposed downstream of the twist stop guide 12 in the yarn running direction and upstream of the cooling device 14 in the yarn running direction. In this embodiment, for simplicity of explanation, the first heating device 13 is configured to heat one yarn Y, but this is not limiting. The first heating device 13 may also be configured to be able to heat multiple yarns Y simultaneously.

[0045] The cooling device 14 is configured to cool the yarn Y heated by the first heating device 13. The cooling device 14 is disposed downstream in the yarn running direction of the first heating device 13 and upstream in the yarn running direction of the false twist device 15. In this embodiment, for simplicity of explanation, the cooling device 14 is configured to cool one yarn Y, but is not limited to this. The cooling device 14 may be configured to be able to cool multiple yarns Y simultaneously.

[0046] The false twist device 15 is configured to impart a twist to the yarn Y. The false twist device 15 is, for example, but not limited to, a so-called disk friction type false twist device. The false twist device 15 is disposed downstream of the cooling device 14 in the yarn running direction and upstream of the second feed roller 16 in the yarn running direction.

[0047] The second feed rollers 16 are configured to feed the yarn Y processed by the false twist device 15 to the second heating device 17. The conveying speed of the yarn Y by the second feed rollers 16 is faster than the conveying speed of the yarn Y by the first feed rollers 11. As a result, the yarn Y is stretched between the first feed rollers 11 and the second feed rollers 16. Information about the set value of the conveying speed of the yarn Y by the second feed rollers 16 is stored in advance in, for example, the machine control device 5.

[0048] The second heating device 17 is configured to heat the yarn Y fed from the second feed roller 16. The second heating device 17 extends in the vertical direction. For simplicity of explanation, the second heating device 17 is configured to heat one yarn Y, but is not limited to this. The second heating device 17 may also be configured to be able to heat multiple yarns Y simultaneously.

[0049] The third feed roller 18 is configured to feed the yarn Y heated by the second heating device 17 to the winding device 19. The speed at which the yarn Y is conveyed by the third feed roller 18 is slower than the speed at which the yarn Y is conveyed by the second feed roller 16. The yarn Y is relaxed between the second feed roller 16 and the third feed roller 18. Information about the set value of the speed at which the yarn Y is conveyed by the third feed roller 18 is stored in advance in, for example, the machine control device 5.

[0050] A yarn feeler 41 is disposed downstream in the yarn traveling direction of the third feed roller 18 and upstream in the yarn traveling direction of the winding device 19 (described later). The yarn feeler 41 is configured to be able to detect whether the yarn Y is traveling between the third feed roller 18 and the winding device 19 in the yarn traveling direction.

[0051] In the processing unit 3 configured as described above, the yarn Y drawn between the first feed roller 11 and the second feed roller 16 is twisted by the false twist device 15. The twist formed by the false twist device 15 propagates to the twist stop guide 12 but does not propagate upstream of the twist stop guide 12 in the yarn traveling direction. The yarn Y, which has been drawn and twisted, is heated and heat-set by the first heating device 13 and then cooled by the cooling device 14. The yarn Y is untwisted downstream from the false twist device 15, but the heat-set maintains the wavy false-twisted state of each filament. Furthermore, the yarn Y false-twisted by the false twist device 15 is relaxed between the second feed roller 16 and the third feed roller 18, heat-set by the second heating device 17, and then guided downstream in the yarn traveling direction. Finally, the yarn Y fed from the third feed roller 18 is wound onto a winding bobbin Bw by the winding device 19. This forms a winding package Pw.

[0052] (winding section) The configuration of the winding unit 4 will be described with reference to Figures 2 and 3. The winding unit 4 has a plurality of winding devices 19 that wind the yarn Y onto winding bobbins Bw, and a plurality of auto doffers 10 (see Figure 2) provided corresponding to each winding device 19. Each of the plurality of winding devices 19 corresponds to a plurality of spindles 9 (see Figure 3). Each winding device 19 has, 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 is traversed. The traverse device 32 is configured to traverse the yarn Y using, for example, a traverse guide 35 attached to an endless belt that is reciprocally driven by a motor. The cradle 33 is configured to rotatably support the winding bobbin Bw (winding package Pw). The winding roller 34 is configured to rotate the winding package Pw and apply contact pressure to the surface of the winding package Pw. The winding roller 34 is, for example, driven to rotate by a motor (not shown) while in contact with the surface of the winding package Pw. As a result, the winding package Pw is driven to rotate by frictional force, and contact pressure is applied to the surface of the winding package Pw, thereby shaping the winding package Pw. Note that instead of driving the winding roller 34 to rotate, the winding package Pw may be directly driven to rotate by a motor (not shown).

[0053] The auto doffer 10 is configured to remove the winding package Pw from the winding device 19 and attach an empty winding bobbin Bw to the winding device 19. In other words, the auto doffer 10 is configured to be able to exchange the formed winding package Pw for an empty winding bobbin Bw in the winding section 4. The auto doffer 10 also has a cutter (not shown) that can cut the yarn Y near the winding package Pw. The running yarn Y is cut by the cutter, thereby completing the formation of the winding package Pw. Even after the yarn Y is cut by the cutter, the yarn Y continues to be unwound from the yarn supply package Ps at approximately the same speed as when it is wound onto the winding bobbin Bw and supplied to the winding device 19. The auto doffer 10 has a suction (not shown) that can suck, capture, and hold the running yarn Y supplied to the winding device 19 after the winding package Pw is formed and until the yarn Y starts to be wound onto the next winding bobbin Bw. The portion of the yarn Y that has been sucked by the suction is sucked and removed until the yarn Y is wound onto the next winding bobbin Bw. For more details on the structure of the auto doffer 10, see, for example, Japanese Patent Application Laid-Open No. 6-212521.

[0054] The auto doffer 10 also has a stocker 10a. The stocker 10a is configured to temporarily store winding packages Pw (hereinafter referred to as completed packages PwC) that have been formed and removed from the winding device 19. The stocker 10a faces, for example, a space formed between the creel stand 6 and the winding table 8. Completed packages PwC temporarily stored in the stocker 10a (stored packages PwS) are collected, for example, by an operator. In this embodiment, the stocker 10a provided on each of the multiple spindles 9 is configured to temporarily store multiple completed packages PwC. The stocker 10a has a stored package detection unit 42 configured to detect the number of multiple stored packages PwS. The stored package detection unit 42 has, for example, multiple sensors (not shown). Each sensor may be, for example, a reflective optical sensor. Each sensor is configured to detect one stored package PwS. The machine control device 5 acquires information on the number of stored packages PwS temporarily stored in the stocker 10a based on the detection result by the stored package detection unit 42. The stored packages PwS are collected by, for example, an operator.

[0055] Further, for example, a threading device (not shown) is provided near the winding device 19. The threading device is configured to hook the yarn Y onto an empty winding bobbin Bw attached to the winding device 19.

[0056] In the winding section 4 configured as described above, the yarn Y fed from the third feed roller 18 is wound onto the winding bobbin Bw by the winding devices 19 to form a winding package Pw (winding process). The yarn Y is cut by the cutter of the auto doffer 10, completing the winding process of the yarn Y onto the winding bobbin Bw. Almost simultaneously, the yarn Y supplied to the winding device 19 is sucked and held by suction, and the auto doffer 10 removes the winding package Pw from the cradle 33. Immediately thereafter, the auto doffer 10 attaches a new, empty winding bobbin Bw to the cradle 33. Furthermore, the yarn hooking device hooks the yarn Y onto the new winding bobbin Bw. This makes it possible to start winding the yarn Y onto the new winding bobbin Bw. Hereinafter, for convenience of explanation, the winding package Pw being formed by the winding device 19 will be referred to as the package in progress PwM.

[0057] Generally, in a manufacturing factory where yarn processing equipment 100 is installed and processed yarn is produced, inventory valuation is performed as needed. At that time, the asset value of the unprocessed yarn Y, which is a current asset, is also evaluated. For this purpose, it is necessary to consider not only the total amount of yarn Y contained in each of the multiple yarn supply packages Ps before use, but also the individual remaining amounts of yarn Y contained in each of the multiple yarn supply packages Ps from which the yarn Y is unwound (i.e., in use) and their total value (total remaining amount). However, in conventional equipment, to obtain information on the remaining amount of yarn Y for each of the multiple yarn supply packages Ps in use (hereinafter referred to as multiple unwound packages), an operator must first visually check each unwound package one by one. Under these circumstances, with the recent trend toward increasingly mass production, it is difficult to simultaneously know the remaining amounts of yarn Y for multiple unwound packages. Therefore, it is extremely difficult to appropriately obtain information on the total remaining amount. Furthermore, obtaining information on the total remaining amount may impose a heavy burden on the operator.

[0058] Furthermore, in such manufacturing plants, when evaluating inventory, the asset value of the winding package Pw in the process of being formed, which is a current asset, is also evaluated. For this purpose, it is necessary to take into account not only the total amount of the yarn Y contained in each of the multiple formed winding packages Pw, but also the individual winding amounts of the yarn Y contained in each of the multiple winding packages Pw into which the yarn Y is wound (i.e., being formed) and their total value (total winding amount). However, in conventional equipment, to obtain information on the winding amount of the yarn Y for each of the multiple winding packages Pw in the process of being formed (multiple packages in the process of being formed PwM), an operator must first visually inspect each package in the process of being formed. Under these circumstances, with the recent trend toward increasingly mass production, it is difficult to simultaneously determine the winding amount of the yarn Y for multiple packages in the process of being formed. Therefore, it is extremely difficult to appropriately obtain information on the total winding amount. Furthermore, obtaining information on the total winding amount may place a heavy burden on the operator.

[0059] Therefore, in order to easily obtain information on the individual or total remaining amounts of the yarn Y contained in the multiple packages being unwound and the individual or total wound amounts of the yarn Y contained in the multiple packages being formed PwM, and to reduce the burden on the operator in obtaining this information, the information management unit 110 performs information processing as described below. As a specific example, the information management unit 110 obtains and manages various information on events shown in the graphs of Figures 4(a) to 4(c). Note that, hereinafter, unless otherwise specified, the description will be limited to one predetermined spindle 9 among the multiple spindles 9.

[0060] (Example of an event) Before specifically describing the information acquired by the information management unit 110, the events illustrated in the graphs of Figures 4(a) to 4(c) and the time at which each event occurred will be described as a premise to help understand the following description. The information management unit 110 acquires information relating to at least some of the events shown in the graphs of Figures 4(a) to 4(c) (details will be described later). Each time described here is not a time predicted by some means, but the time at which each event actually occurs.

[0061] FIG. 4(a) is a graph showing the relationship between the remaining amount (vertical axis) of the yarn Y contained in the yarn supply package Ps (specifically, yarn supply packages Ps1 and Ps3) attached to the first attachment unit 22 and time (horizontal axis). FIG. 4(b) is a graph showing the relationship between the remaining amount (vertical axis) of the yarn Y contained in the yarn supply package Ps (specifically, yarn supply package Ps2) attached to the second attachment unit 23 and time (horizontal axis). FIG. 4(c) is a graph showing the relationship between the amount (vertical axis) of the yarn Y wound onto the winding bobbin Bw (specifically, winding bobbins Bw1, Bw2, Bw3, Bw4, Bw5, and Bw6) and time (horizontal axis). In all of the graphs in FIGS. 4(a) to 4(c), the origin is time t0, when the yarn Y starts to be wound onto the winding bobbin Bw1. In this embodiment, the weight (initial weight) of each yarn supply package Ps in a state where the yarn Y has never been unwound from the yarn supply package Ps (that is, in a full wound state) is WF.

[0062] First, at time t0, yarn supply package Ps1 is loaded into first loading unit 22. Yarn supply package Ps2 is loaded into second loading unit 23. The remaining weight of yarn Y contained in yarn supply package Ps1 is W0 (less than WF). The remaining weight of yarn Y contained in yarn supply package Ps2 is WF. The end of yarn Y contained in yarn supply package Ps1 and the beginning of yarn Y contained in yarn supply package Ps2 are knotted together to form knot K.

[0063] At time t0 (time ts1), the auto doffer 10 completes the attachment of the winding bobbin Bw1 to the cradle 33, and the winding of the yarn onto the winding bobbin Bw1 begins. That is, time ts1 is the winding start time when the yarn Y begins to be wound onto the winding bobbin Bw1. At this time, the yarn Y is unwound from the yarn supply package Ps1. As time passes, the remaining amount (remaining weight) of the yarn Y contained in the yarn supply package Ps1 decreases, and the winding amount (winding weight) of the yarn Y wound onto the winding bobbin Bw1 increases. At time te1, the yarn Y is cut by the cutter of the auto doffer 10, and the winding process of the yarn Y onto the winding bobbin Bw1 ends. That is, time te1 is the winding end time when the winding of the yarn Y onto the winding bobbin Bw1 ends (the formation of the winding package Pw1 ends). Only the yarn Y supplied from the yarn supply package Ps1 is wound onto the winding bobbin Bw1. The cutting of the yarn Y by the cutter, the suction capture of the yarn Y by suction (i.e., the start of suction removal of the yarn Y), and the removal of the winding bobbin Bw1 (winding package Pw1) from the cradle 33 are performed almost simultaneously. Next, at time ts2 immediately after time te1, the auto doffer 10 completes the attachment of the winding bobbin Bw2 to the cradle 33, and starts winding the yarn Y onto the winding bobbin Bw2 (the winding bobbin replacement operation is completed). There is a slight time lag tL between the winding end time (time te1) for the winding bobbin Bw1 and the winding start time (time ts2) for the winding bobbin Bw2 onto which the yarn Y is wound next after the winding bobbin Bw1.

[0064] At time ta1, which is later than time ts2, the yarn supply package Ps1 attached to the first attachment unit 22 becomes empty. In other words, time ta1 is the unwinding end time when the yarn Y has been completely unwound from the yarn supply package Ps1. At the same time that the yarn supply package Ps1 becomes empty, at time tb1 (=time ta1), the knot K formed by knotting the yarn Y included in the yarn supply package Ps1 and the yarn Y included in the yarn supply package Ps2 is pulled toward the winding device 19. As a result, the yarn Y is first unwound from the yarn supply package Ps2 attached to the second attachment unit 23. In other words, time tb1 is the unwinding start time when the yarn Y is first unwound from the yarn supply package Ps2 (when the yarn Y starts to be unwound). Furthermore, at time te2, the winding process of the yarn Y onto the winding bobbin Bw2 (forming the winding package Pw2) ends, and at time ts3, the winding process of the yarn Y onto the winding bobbin Bw3 starts. At time te3, the winding process of the yarn Y onto the winding bobbin Bw3 (forming the winding package Pw3) ends.

[0065] Furthermore, at time ta2, which is after time ta1 and before the yarn supply package Ps2 becomes empty, the yarn supply package Ps1 is removed from the first installation unit 22 and the yarn supply package Ps3 is installed in the first installation unit 22, for example, by an operator. At this time, the remaining weight of the yarn supply package Ps3 is WF. Thereafter, at an appropriate timing, the operator knots the end of the yarn Y contained in the yarn supply package Ps2 and the beginning of the yarn Y contained in the yarn supply package Ps3 to form a knot K. The operator may perform the knotting operation manually. Alternatively, the operator may perform the knotting operation by operating, for example, a portable knotting device (not shown).

[0066] Subsequent events will be briefly described. Events related to the winding unit 4 are as follows: From time ts4 to time te4, the yarn Y is wound onto the winding bobbin Bw4 (the winding package Pw4 is formed). From time ts5 to time te5, the yarn Y is wound onto the winding bobbin Bw5 (the winding package Pw5 is formed). From time ts6 to time te6, the yarn Y is wound onto the winding bobbin Bw6 (the winding package Pw6 is formed). Furthermore, events related to the yarn supplying unit 2 are as follows: At time tb2 (= time ta3) between time ts4 and time te4, the yarn supply package Ps2 becomes empty, and the yarn Y begins to be unwound from the yarn supply package Ps3. Thereafter, at time tb3, the yarn supply package Ps2 is replaced with the yarn supply package Ps4. At time ta4 (=time tb4) between time ts6 and time te6, the yarn supply package Ps3 becomes empty, and the yarn Y starts to be unwound from the yarn supply package Ps4.

[0067] (Basic information of yarn supply package) Considering the above, we will first explain the basic information of the yarn supply package Ps acquired by the information management unit 110. The information management unit 110 acquires, as the basic information of the yarn supply package Ps, for example, initial amount information, unwinding unit amount information, and accumulated unwinding time information of each yarn supply package Ps. These pieces of information can be used to acquire management information of each yarn supply package Ps (details of which will be described later).

[0068] The initial amount information is information about the initial amount (initial weight or initial length) of yarn Y contained in the yarn supply package Ps before the yarn Y starts to be unwound. The initial amount information is, for example, set in advance in the machine control device 5 as common information related to all yarn supply packages Ps of all spindles 9 of one false twisting machine 1. More specifically, in this embodiment, the above-mentioned information on the initial weight (i.e., WF) and information on the fineness of the yarn Y (weight per unit length) are stored as initial amount information in the machine control device 5. The unit of the weight of the yarn supply package Ps is, for example, kg. The fineness of the yarn Y is assumed to be F. The unit of fineness is, for example, dtex (decitex). Decitex is the weight (g) of the yarn Y per 10,000 meters.

[0069] The unwinding unit amount information is information relating to the amount of yarn Y unwound from the yarn supply package Ps per unit time. The unwinding unit amount information is, for example, information about the unwinding speed Vu described above. In this embodiment, for the sake of convenience, it is assumed that the unwinding speed Vu is approximately constant during the winding process. The unit of the unwinding speed is, for example, m / min. The unwinding unit amount information is, for example, set in advance in the machine control device 5 as common information for all spindles 9 of one false twisting machine 1. The machine control device 5 acquires the information about the unwinding speed Vu based on, for example, information about the set value of the rotation speed of the first feed roller 11.

[0070] The accumulated unwinding time information is information related to the accumulated value of the time (accumulated unwinding time) during which the yarn Y is unwound from the yarn supply package Ps. For convenience of explanation, the accumulated unwinding time related to the yarn supply package Ps from which the yarn Y is unwound is referred to as tinU. The accumulated unwinding time information is acquired as follows. During the winding process, the machine control device 5 determines whether a yarn supply package switch, in which the yarn supply package Ps supplying the yarn Y is switched, has occurred, based on the detection result of the yarn detection sensor 24. For example, with reference to FIGS. 4(a) and 4(b), a yarn supply package switch occurs when the yarn Y from the yarn supply package Ps1 has finished being unwound (unwinding end) and the yarn Y is first unwound from the yarn supply package Ps2. When the state of the yarn detection sensor 24 switches from a state in which the yarn Y is detected by one of the first detection unit 25 and the second detection unit 26 to a state in which the yarn Y is detected by the other of the first detection unit 25 and the second detection unit 26, the machine control device 5 determines that a yarn supply package switch has occurred. When the machine control device 5 determines that a yarn supply package switch has occurred, the machine control device 5 sets tinU to a predetermined initial time (reset process). The initial time is, for example, zero. The machine control device 5 may obtain and store information about the unwinding start time (i.e., time ta1) at which the yarn Y begins to be unwound from the yarn supply package Ps2.

[0071] Thereafter, while the yarn Y is being unwound from the yarn supply package Ps2, the machine control device 5 increases tinU (updates tinU) as time passes. Furthermore, when the unwinding of the yarn Y from the yarn supply package Ps2 is temporarily stopped due to a yarn breakage or other reason, the machine control device 5 temporarily stops updating tinU. In this way, the machine control device 5 acquires only the time (detection time) at which the yarn detection sensor 24 detects that the yarn Y has been unwound from the yarn supply package Ps2 as the accumulated unwinding time (tinU). Similarly, when the unwinding of the yarn Y from the yarn supply package Ps2 is completed and the unwinding of the yarn Y from the yarn supply package Ps3 begins, the machine control device 5 also performs the reset process described above (sets tinU to the initial time) based on the detection result of the yarn detection sensor 24. Thereafter, the machine control device 5 updates tinU as time passes, thereby acquiring information on the accumulated unwinding time at which the yarn Y has been unwound from the yarn supply package Ps3. In this way, when the yarn Y is being unwound from any yarn supply package Ps, the machine control device 5 can acquire the accumulated unwinding time information related to that yarn supply package Ps.

[0072] In this manner, the information management unit 110 acquires the initial amount information, the unwinding unit amount information, and the accumulated unwinding time information as basic information of the yarn supply package Ps.

[0073] (Information on replacing yarn supply packages and knotting) In addition, as an explanation related to the above-mentioned yarn supply package switching, information acquired by the information management unit 110 when an empty yarn supply package Ps is replaced with a new yarn supply package during the winding process will be described. When the yarn supply package Ps attached to one of the package attachment units 21 is empty, the operator removes the empty yarn supply package Ps from that one of the package attachment units 21 and attaches a new yarn supply package Ps to that one of the package attachment units 21. The operator then knots the leading end of the yarn Y included in the new yarn supply package Ps with the trailing end of the yarn Y included in the yarn supply package Ps attached to the other package attachment unit 21 to form a knot K. Next, the operator places the knot K in a predetermined position. Furthermore, the operator inputs information indicating that the knot K has been placed in the predetermined position (for convenience of explanation, this information will be referred to as placement information) to the machine control device 5. When such an input operation is performed, the machine control device 5 stores the placement information. Thereafter, when a yarn supply package switch occurs, the machine control device 5 performs the above-mentioned reset process and stores information indicating that the knot portion K has moved from the predetermined position (for convenience of explanation, this information will be referred to as movement information).

[0074] (Setting the yarn feed information reference time) The information management unit 110 is configured to set a yarn supply information reference time, which is a reference for acquiring management information for a yarn supply package Ps. In this embodiment, the yarn supply information reference time refers to the time (timing) at which the information management unit 110 executes a process for acquiring management information for a yarn supply package Ps. For example, the information management unit 110 stores multiple options for setting the yarn supply information reference time. The information management unit 110 determines whether the yarn supply information reference time has arrived based on one setting selected from the multiple options through an input operation to the machine input unit 5a. The multiple options include, for example, "always," "at a predetermined operation," and "reserved." If "always" is selected, the information management unit 110 determines that the yarn supply information reference time has arrived every time a predetermined first time period has elapsed. The information management unit 110 may store the first time period in an unchangeable manner. Alternatively, the information management unit 110 may be configured to newly set and / or rewrite the first time period in response to an input by an operator to the machine input unit 5a. If "at a predetermined operation" is selected, the information management unit 110 determines that the yarn feeding information reference time has arrived when a predetermined operation is performed on the machine input unit 5a. In this case, for example, the time when the predetermined operation is performed is the yarn feeding information reference time. If "reservation" is selected, the information management unit 110 determines that the yarn feeding information reference time has arrived when a first reservation time set by an operator via the machine input unit 5a arrives. The first reservation time is a time in the future than the time when the operator is performing the input operation. The information management unit 110 is configured to be able to reselect (change) the setting related to the yarn feeding information reference time in accordance with an input by the operator to the machine input unit 5a. Information related to the setting of the yarn feeding information reference time corresponds to the yarn feeding setting information of the present invention.

[0075] (Method for obtaining management information of yarn supply package) Next, an example of a method by which the information management unit 110 acquires management information on the yarn supply package Ps will be described. In this embodiment, the management information on the yarn supply package Ps includes information on the remaining amount. The remaining amount is, for example, an estimated value of the amount (more precisely, weight) of yarn Y contained in the yarn supply package Ps from which the yarn Y is unwound at the yarn supply information reference time described above. When the remaining amount (remaining weight) is Wr, the value of Wr can be calculated, for example, based on the formula described below using the value of tinU at the yarn supply information reference time. In the formula below, A is a coefficient for converting the unit of the calculation result based on the formula in parentheses to kg. The information management unit 110 is configured to estimate the remaining amount of the yarn supply package Ps from which the yarn Y is unwound for each of the multiple spindles 9 included in each of the multiple false twisting machines 1. For convenience of explanation, the remaining amount for any one spindle 9 will be referred to as the individual remaining amount.

[0076] Wr = WF-(A × Vu × F × tinU)

[0077] The information management unit 110 may calculate a predicted value of the length of time (remaining time) until the yarn Y is completely unwound from the yarn supply package Ps from which the yarn Y is unwound at the yarn supply information reference time. When the remaining time for the yarn supply package Ps from which the yarn Y is unwound at the yarn supply information reference time is tR, the value of tR can be calculated based on, for example, one of the following two equations. Note that the information management unit 110 may calculate the remaining time based on the lower of the two equations, and then calculate the remaining amount using information on the remaining time.

[0078] tR=WR / (A×Vu×F) tR={WF-(A×Vu×F×tinU)} / (A×Vu×F)

[0079] (Basic information on the rewinding package) Next, we will explain the basic information of the winding package Pw acquired by the information management unit 110. The information management unit 110 acquires, as the basic information of each winding package Pw, information on the thickness of the yarn Y to be processed and wound onto the winding bobbin Bw, information on the winding speed, and information on the accumulated winding time. This information can be used to acquire management information (details of which will be described later) for each winding package Pw.

[0080] For convenience of explanation, the thickness (weight per unit length) of the processed yarn Y will be referred to as Fw. The unit of thickness is, for example, dtex, which is the same as the fineness, that is, the weight (g) of the yarn Y per 10,000 meters. Fw is set in advance in the machine control device 5 as common information related to all winding packages Pw of all spindles 9 of one false twisting machine 1, for example.

[0081] The winding speed information is information related to the winding speed of the yarn Y wound onto the winding bobbin Bw (i.e., the length of the yarn Y wound onto the winding bobbin Bw per unit time). In other words, the winding speed information is information related to the speed at which the winding package Pw is formed. The unit of the winding speed is, for example, m / min. The winding speed information is set in advance in the machine control device 5 as information common to all spindles 9 of one false twisting machine 1. The machine control device 5 acquires the winding speed information based on, for example, information about the set value of the rotation speed of the winding roller 34. For convenience of explanation, the winding speed will be referred to as Vw (see FIG. 3). In this embodiment, for convenience of explanation, it is assumed that the winding speed Vw is approximately constant.

[0082] The accumulated winding time information is information about the accumulated value of the time (accumulated winding time) taken for the yarn Y to be wound onto the winding bobbin Bw. For ease of explanation, the accumulated winding time for the winding bobbin Bw onto which the yarn Y is wound will be referred to as tinW. The accumulated winding time information is acquired as follows. When performing winding processing onto a new, empty winding bobbin Bw, the machine control device 5 controls the auto doffer 10 to attach the winding bobbin Bw to the winding device 19. For example, the machine control device 5 sets tinW to a predetermined initial time (e.g., zero) when starting control of the auto doffer 10. Next, the machine control device 5 controls the above-mentioned threading device (not shown) to thread the winding bobbin Bw attached to the winding device 19. When the yarn feeler 41 detects the yarn Y and the threading operation by the threading device is completed, the machine control device 5 determines that the winding processing has started and starts updating tinW. That is, after determining that the winding process has started, the machine control device 5 increases tinW (updates tinW) as time passes. When any winding package Pw is being formed, the machine control device 5 can acquire the accumulated winding time information related to that winding package Pw.

[0083] When the accumulated winding time on any spindle 9 reaches a predetermined target winding time, the machine control device 5 determines that the winding package Pw is completed on that spindle 9. When the machine control device 5 determines that the winding package Pw is completed, the machine control device 5 controls the auto doffer 10 to remove the winding package Pw from the winding device 19. The winding package Pw removed from the winding device 19 (completed package PwC) is temporarily stored in the stocker 10a (storage package PwS). The weight of the yarn Y contained in the storage package PwS is, for example, a predetermined target weight.

[0084] In this manner, the information management unit 110 acquires the yarn thickness information, the winding speed information, and the integrated winding time information as basic information of the winding package Pw.

[0085] (Setting the winding information reference time) The information management unit 110 is configured to be able to set a winding information reference time that serves as a reference for acquiring management information about the winding package Pw. In this embodiment, the winding information reference time refers to the time (timing) at which the information management unit 110 executes a process for acquiring management information about the winding package Pw. For example, the information management unit 110 stores multiple options for setting the winding information reference time. The information management unit 110 determines whether the winding information reference time has arrived based on one setting selected from the multiple options through an input operation to the machine input unit 5a. The multiple options include, for example, "always," "at a predetermined operation," and "reserved." If "always" is selected, the information management unit 110 determines that the winding information reference time has arrived every time a predetermined second time period has elapsed. The information management unit 110 may store the second time period in an unchangeable manner. Alternatively, the information management unit 110 may be configured to newly set and / or rewrite the second time period in response to an operator's input to the machine input unit 5a. The second time period may be the same length as the first time period described above, or may be different from the first time period. When "at a predetermined operation" is selected, the information management unit 110 determines that the winding information reference time has arrived when a predetermined operation is performed on the machine input unit 5a. In this case, for example, the time when the predetermined operation is performed is the winding information reference time. When "reservation" is selected, the information management unit 110 determines that the winding information reference time has arrived when a second reservation time set by an operator via the machine input unit 5a arrives. The second reservation time is a time in the future relative to the time when the operator is performing the input operation. The second reservation time may be the same time as the first reservation time, or may be a time different from the first reservation time. The information management unit 110 is configured to be able to reselect (change) the setting related to the winding information reference time in accordance with an input by the operator to the machine input unit 5a. Information related to the setting of the winding information reference time corresponds to the winding setting information of the present invention.

[0086] The information management unit 110 may be configured to be able to set the yarn supplying information reference time and the winding information reference time separately. Alternatively, the information management unit 110 may be configured to be able to set an "information acquisition time" that is treated as both the yarn supplying information reference time and the winding information reference time.

[0087] (Method for acquiring management information of winding package) Next, an example of a method by which the information management unit 110 acquires management information about the winding package Pw will be described. In this embodiment, the management information about the winding package Pw includes information about the winding amount. The winding amount is the amount (more strictly speaking, weight) of the yarn Y included in the winding package Pw (package being formed PwM) formed at the winding information reference time described above. When the winding amount (winding weight) is Ww, the value of Ww can be calculated, for example, based on the following formula using the value of tinW at the winding information reference time: A is the coefficient described above. For convenience of explanation, the winding amount related to any one spindle 9 will be referred to as an individual winding amount.

[0088] Ww=A×Vw×Fw×tinW

[0089] (Calculation and output of total remaining amount, and calculation and output of total winding amount) Next, procedures for calculating and outputting the total remaining amount and the total winding amount will be described with reference to FIGS. 5 to 7(b). FIG. 5 is a flowchart for calculating and outputting the total remaining amount of yarn Y contained in multiple unwinding packages. FIG. 6 is a flowchart for calculating and outputting the total winding amount of yarn Y contained in multiple packages PwM being formed. FIG. 7(a) is an explanatory diagram showing a screen S1 on which the total remaining amount and total winding amount are displayed. FIG. 7(b) is an explanatory diagram showing a screen S2 on which various menus are displayed. For ease of explanation, as an example, the machine input unit 5a has a touch panel arranged to overlap the display 5b1. Below, as a specific example, the total remaining amount and total winding amount of the false twisting machine 1A (see FIG. 1) will be described. Furthermore, it is assumed that the machine control device 5, which is part of the information management unit 110 and controls the false twisting machine 1A, performs the following processing. However, this is not limited to this, and any device constituting the information management unit 110 may perform the following processing.

[0090] The procedure for calculating and outputting the total remaining amount will be described. First, the machine control device 5 calculates the accumulated unwinding time at the above-mentioned yarn feeding information reference time. That is, the machine control device 5 calculates the accumulated unwinding time for each yarn feeding package Ps (i.e., the package being unwound) that is attached to the yarn feeding package holder 20 of each of the multiple spindles 9 included in the false twisting machine 1A and from which the yarn Y is being unwound (S101). Next, the machine control device 5 calculates the individual remaining amount (Wr) for the package being unwound for each of the multiple spindles 9, for example, based on the above-mentioned formula (S102). Information on the individual remaining amount for each spindle 9 is included in the individual remaining amount information of the present invention. Hereinafter, for convenience of explanation, the process of acquiring the individual remaining amount information will be referred to as the individual remaining amount information acquisition process. Note that the individual remaining amounts at the yarn feeding information reference time may differ among the multiple spindles 9. This is because the unwinding start times may differ among multiple spindles 9, and temporary unwinding stops may occur due to yarn breakage or forced yarn cutting in each spindle 9. The individual remaining amount content information may be information on the individual remaining amount itself, or may be information obtained by adding another value to the individual remaining amount.

[0091] Next, the machine control device 5 calculates the total remaining amount, which is a value obtained by adding up the individual remaining amounts for all of the multiple spindles 9 included in the false twisting machine 1A (S103). The information on the total remaining amount corresponds to the total remaining amount content information of the present invention. For convenience of explanation, the process of acquiring the total remaining amount content information will be referred to as the total remaining amount information acquisition process below.

[0092] Each of the multiple machine control devices 5 included in the yarn processing equipment 100 performs individual remaining amount information acquisition processing and / or total remaining amount information acquisition processing for the corresponding false twisting machine 1. In other words, the information management unit 110 performs individual remaining amount information acquisition processing for each of the multiple false twisting machines 1. and The information management unit 110 performs individual remaining amount information acquisition processing for each of some of the plurality of false twisting machines 1. and Or, a total remaining amount information acquisition process may be performed.

[0093] Next, the machine control device 5 displays, for example, the machine identification number assigned to the false twisting machine 1A, information on the individual remaining amounts for each spindle 9, and information on the calculated total remaining amount on the display 5b1 of the machine output unit 5b (S104; see screen S1 in Figure 7(a)). This allows the operator to see at a glance the individual remaining amounts and total remaining amounts of multiple packages being unwound in the false twisting machine 1A. The machine identification number information does not necessarily have to be displayed. Also, only one of the individual remaining amount information and the total remaining amount information may be displayed.

[0094] The machine control device 5 is also configured to display on the display 5b1 a menu for the operator to perform input operations. As a simple example, when the operator touches the "Menu" button (see FIG. 7(a)) displayed on the screen S1, the machine control device 5 displays a menu screen (screen S2) on the display 5b1 based on the input results to the machine input unit 5a (see FIG. 7(b)). The machine control device 5 determines whether or not the operator has performed a predetermined operation for output on the machine input unit 5a (S105). If an operation for output has been performed (S105: Yes), the machine control device 5 executes output processing according to the input results to the machine input unit 5a. If an operation for output has not been performed (S105: No), the machine control device 5 ends the series of processes.

[0095] The output process includes, for example, the following processes: When the operator touches the "Print" button, the base control device 5 controls the printer 5b2 to print information on the individual remaining amounts and / or the total remaining amount onto a print medium such as paper. When the operator touches the "File Output" button, the base control device 5 generates a known CSV file (an electronic file of the present invention) containing information on the individual remaining amounts and / or the total remaining amount. The base control device 5 stores the file in the base storage unit 5c. In this case, the base control device 5 functions as the output unit and generation unit of the present invention. When the operator touches the "Add Data" button, the base control device 5 executes a process of adding data containing information on the individual remaining amounts and / or the total remaining amount to an existing file. In this case, the base control device 5 functions as the output unit of the present invention. When the operator touches the "Send Data" button, the base control device 5 transmits data containing information on the individual remaining amounts and / or the total remaining amount to another computer device. In this case, the base control device 5 functions as the output unit and communication unit of the present invention. The data may be transmitted to, for example, a machine control device 5 that controls a false twisting machine 1 (e.g., false twisting machine 1B) other than the false twisting machine 1A. Alternatively, the data may be transmitted to the management device 101. Alternatively, the data may be transmitted to an external computer other than the information management unit 110. The external computer is not limited to a general PC, but may be any device capable of viewing and / or processing information, such as a host computer, a mobile phone, or a tablet terminal.

[0096] Hereinafter, for ease of explanation, the process of outputting individual remaining content information will be referred to as the individual remaining content information output process. Similarly, the process of outputting total remaining content information will be referred to as the total remaining content information output process. The information management unit 110 may perform the individual remaining content information output process and / or the total remaining content information output process for a predetermined false twisting machine group (yarn processing machine group of the present invention) including at least some of multiple false twisting machines 1. A false twisting machine group means, for example, "a group including at least some of the false twisting machines 1 installed in one room (or one building, one business establishment, etc.) out of multiple false twisting machines 1 installed in one or more rooms (or one or more buildings, one or more business establishments, etc.)."

[0097] Next, the procedure for calculating and outputting the total winding amount will be described. First, the machine control device 5 calculates the cumulative winding time at the winding information reference time described above. That is, the machine control device 5 calculates the cumulative winding time described above for the winding package Pw (i.e., the package PwM) currently being formed, which is attached to each winding device 19 of the multiple spindles 9 included in the false twisting machine 1A and onto which the yarn Y is being wound (S201). Next, the machine control device 5 calculates the individual winding amount (Ww) for the currently being formed package PwM for each of the multiple spindles 9, for example, based on the above-mentioned formula (S202). Information on the individual winding amount for each spindle 9 is included in the individual winding amount information of the present invention. Hereinafter, for convenience of explanation, the process of acquiring the individual winding amount information will be referred to as the individual winding amount information acquisition process. Note that the individual winding amounts at the winding information reference time may differ among the multiple spindles 9. This is because the winding start times may differ among the plurality of spindles 9, and winding may be temporarily stopped due to yarn breakage or forced yarn cutting in each spindle 9, etc.

[0098] Next, the machine control device 5 calculates the total winding amount, which is a value obtained by adding up the individual winding amounts for all of the spindles 9 included in the false twisting machine 1A (S203). The information on the total winding amount corresponds to the total winding amount content information of the present invention. For convenience of explanation, the process of acquiring the total winding amount content information will be referred to as the total winding amount information acquisition process below.

[0099] Each of the multiple machine control devices 5 included in the yarn processing equipment 100 performs an individual winding amount information acquisition process and a total winding amount information acquisition process for the corresponding false twisting machine 1. In other words, the information management unit 110 performs an individual winding amount information acquisition process for each of the multiple false twisting machines 1. Alternatively, the information management unit 110 may perform an individual winding amount information acquisition process and a total winding amount information acquisition process for each of some of the multiple false twisting machines 1.

[0100] Next, the machine control device 5 displays, for example, the machine identification number assigned to the false twisting machine 1A, information on the individual winding amounts for each spindle 9, and information on the calculated total winding amount on the display 5b1 of the machine output unit 5b (S204; see screen S1 in Figure 7(a)). This allows the operator to know at a glance the total winding amount of the multiple packages PwM being formed in the false twisting machine 1A. The machine identification number information does not necessarily have to be displayed. Also, only one of the individual winding amount information and the total winding amount information may be displayed.

[0101] 7(a), the machine control device 5 may be configured to simultaneously display information on the total remaining amount and information on the total wound amount on the display 5b1. Alternatively, the machine control device 5 may be configured to be able to switch the display mode between a mode in which information on the total remaining amount is displayed on the display 5b1 and a mode in which information on the total wound amount is displayed on the display 5b1.

[0102] The machine control device 5 is also configured to display on the display 5b1 a menu for the operator to perform input operations. As a simple example, when the operator touches the "Menu" button (see FIG. 7(a)) displayed on the screen S1, the machine control device 5 displays a menu screen (screen S2) on the display 5b1 based on the input results to the machine input unit 5a (see FIG. 7(b)). The machine control device 5 determines whether or not the operator has performed a predetermined operation for output on the machine input unit 5a (S205). If an operation for output has been performed (S205: Yes), the machine control device 5 executes output processing according to the input results to the machine input unit 5a. If an operation for output has not been performed (S205: No), the machine control device 5 ends the series of processes.

[0103] The output process includes, for example, the following processes: When the operator touches the "Print" button, the machine control device 5 controls the printer 5b2 to print information on the individual winding amounts and / or the total winding amount on a print medium such as paper. When the operator touches the "File Output" button, the machine control device 5 generates a known CSV file (an electronic file of the present invention) containing information on the individual winding amounts and / or the total winding amount. The machine control device 5 stores the file in the machine storage unit 5c. In this case, the machine control device 5 functions as the output unit and generation unit of the present invention. When the operator touches the "Add Data" button, the machine control device 5 executes a process of adding data containing information on the individual winding amounts and / or the total winding amount to an existing file. In this case, the machine control device 5 functions as the output unit of the present invention. When the operator touches the "Send Data" button, the machine control device 5 transmits data containing information on the individual winding amounts and / or the total winding amount to another computer device. In this case, the machine control device 5 functions as the output unit and communication unit of the present invention. The data may be transmitted to, for example, a machine control device 5 that controls a false twisting machine 1 (e.g., false twisting machine 1B) other than the false twisting machine 1A. Alternatively, the data may be transmitted to the management device 101. Alternatively, the data may be transmitted to an external computer other than the information management unit 110. The external computer is not limited to a general PC, but may be any device capable of viewing and / or processing information, such as a host computer, a mobile phone, or a tablet terminal.

[0104] Hereinafter, for convenience of explanation, the process of outputting the individual winding amount content information will be referred to as the “individual winding amount information output process.” Similarly, the process of outputting the total winding amount content information will be referred to as the “total winding amount information output process.” The information management unit 110 may perform the individual winding amount information output process and / or the total winding amount information output process for the above-mentioned false twisting machine group.

[0105] The machine control device 5 may output all of the individual remaining amount content information, individual wound amount content information, total remaining amount content information, and total wound amount content information during output processing. Alternatively, the machine control device 5 may select and output some of the individual remaining amount content information, individual wound amount content information, total remaining amount content information, and total wound amount content information during output processing.

[0106] The machine control device 5 may execute steps S101 and S201 approximately simultaneously, or may execute them at different times. The machine control device 5 may execute steps S102 and S202 approximately simultaneously, or may execute them at different times. The machine control device 5 may execute steps S103 and S203 approximately simultaneously, or may execute them at different times.

[0107] The configuration of the machine input unit 5a is not limited to the one described above. The machine input unit 5a may include, for example, a mouse (not shown). The machine control device 5 may be configured to display a cursor (not shown) on the display 5b1 and move the cursor when the mouse is operated. The machine control device 5 may be configured to execute a predetermined process when the mouse is clicked while the cursor is over a predetermined button. Of course, the machine input unit 5a may include other means for the operator to perform appropriate input operations.

[0108] In this embodiment, multiple yarn supply packages Ps (unwinding package and spare package) are attached to each yarn supply package holder 20. Therefore, more strictly speaking, it is also necessary to know the total amount of remaining yarn Y contained in the multiple spare packages. The operator may actually count the number of multiple spare packages in the false twisting machine 1A and multiply that number by the value of WF to calculate the total amount of remaining yarn Y contained in the multiple spare packages.

[0109] In this embodiment, it is also necessary to know the total amount of yarn contained in the completed packages PwC temporarily stored in the winding unit 4. As described above, the machine control device 5 acquires information on the number of completed packages PwC (stored packages PwS) temporarily stored in the stocker 10a based on the detection results from the stored package detection unit 42. The machine control device 5 calculates the total amount of yarn contained in one or more stored packages PwS by multiplying the number of stored packages PwS in the false twisting machine 1A by the target weight.

[0110] As described above, the individual remaining amount content information and / or the total remaining amount content information is output by the machine output unit 5b, etc. When at least a portion of the individual remaining amount content information is output, the operator can check the individual remaining amounts for multiple currently unwound packages at a glance. Based on the individual remaining amounts checked at a glance in this manner, the total remaining amount can be obtained by adding up the individual remaining amounts for multiple currently unwound packages. Furthermore, when the total remaining amount content information is output, the total remaining amount can be known in a short time. Therefore, information on the individual remaining amounts and / or the total remaining amounts of the yarn Y contained in multiple currently unwound packages can be easily obtained, and the burden on the operator regarding obtaining the individual remaining amounts and / or the total remaining amounts can be reduced. In particular, the burden on the operator can be significantly reduced by obtaining and outputting the total remaining amount information.

[0111] Furthermore, individual remaining amount information output processing and / or total remaining amount information output processing is performed for a predetermined group of false twisting machines. This makes it possible to obtain individual remaining amount information and / or total remaining amount information for each room, building, or business location where multiple false twisting machines 1 are installed. This allows for efficient inventory evaluation.

[0112] Furthermore, in this embodiment, since multiple yarn supply packages Ps (the currently unwinding package and the spare package) are attached to each yarn supply package holding unit 20, it is also necessary to know the remaining amount of yarn Y contained in the spare package. Even in this configuration, it is possible to output information on the individual remaining amount and / or the total remaining amount related to at least the currently unwinding package, thereby reducing the burden on the operator.

[0113] Furthermore, the operator can know the individual remaining amount information and / or the total remaining amount information simply by looking at the display 5b1.

[0114] Furthermore, the operator can know the individual remaining amount content information and / or the total remaining amount content information simply by looking at the printed matter.

[0115] Furthermore, by opening the generated electronic file, the individual remaining amount information and / or the total remaining amount information can be obtained.

[0116] In addition, the individual remaining amount information and / or the total remaining amount information can be obtained by operating an external computer.

[0117] The information management unit 110 is also configured to allow an operator to input yarn feed setting information related to setting of the yarn feed information reference time, thereby enabling the yarn feed information reference time to be set in accordance with the operator's request.

[0118] Furthermore, the information management unit 110 is configured to be able to set the yarn supply information reference time as any time including a future time based on the yarn supply setting information, thereby making it possible to obtain the individual remaining amount content information and / or the total remaining amount content information at any time.

[0119] Next, a modified example of the embodiment will be described, with the same reference numerals being used to designate components having the same configuration as the embodiment, and the description thereof will be omitted as appropriate.

[0120] (1) In the above embodiment, the machine control device 5 displays the individual remaining amount content information, the individual roll amount content information, the total remaining amount content information, and / or the total roll amount content information on the display 5b1. The machine control device 5 also controls the printer 5b2 to print the individual remaining amount content information, the individual roll amount content information, the total remaining amount content information, and / or the total roll amount content information on a print medium. The machine control device 5 also generates a CSV file (electronic file) including the individual remaining amount content information, the individual roll amount content information, the total remaining amount content information, and / or the total roll amount content information. The machine control device 5 also executes a process of adding data including the individual remaining amount content information, the individual roll amount content information, the total remaining amount content information, and / or the total roll amount content information to an existing file. The machine control device 5 also transmits data including the individual remaining amount content information, the individual roll amount content information, the total remaining amount content information, and / or the total roll amount content information to another computer device. However, this is not limited to this. The machine control device 5 does not have to be configured to perform all of these processes. That is, the machine control device 5 may perform at least one of these processes. Alternatively, the machine control device 5 may perform other output processes that allow the operator to obtain individual remaining amount content information, individual wound amount content information, total remaining amount content information, and / or total wound amount content information.

[0121] (2) In the above-described embodiments, the machine output unit 5b has a display 5b1 and a printer 5b2. However, this is not limited to this. The machine output unit 5b may have, for example, only one of the display 5b1 and the printer 5b2. Alternatively, the machine control device 5 may not have the machine output unit 5b. The machine control device 5 may be configured so that some kind of output device (not shown) can be temporarily connected to it.

[0122] (3) In the above-described embodiments, the machine control device 5 acquires and outputs information on the individual remaining amount as the individual remaining amount information. In addition, the machine control device 5 may be configured to acquire information on the remaining amount (remaining weight) of the yarn Y contained in each of the spare packages attached to the plurality of yarn supply package holders 20 of the false twisting machine 1A, for example. More specifically, the machine control device 5 may be configured as follows, for example. The machine control device 5 may be configured to allow an operator to input information on the remaining amount of the yarn Y contained in each of the spare packages attached to the plurality of yarn supply package holders 20 of the false twisting machine 1A (hereinafter, the "reserve remaining amount"). The value of the reserve remaining amount is, for example, a weight value (unit: kg). The machine control device 5 may treat the value obtained by adding the reserve remaining amount to the individual remaining amount for each spindle 9 as the individual remaining amount information. The reserve remaining amount information corresponds to the reserve remaining amount-related information of the present invention. The machine control device 5 may acquire total remaining amount information based on such individual remaining amount information for the plurality of spindles 9. Alternatively, the machine control device 5 may acquire the total remaining amount information by adding the total value of the spare remaining amounts for the multiple spindles 9 to the total remaining amount. Alternatively, the machine control device 5 may be configured to allow the operator to input information on the number of spare packages attached to each of the multiple yarn supply package holders 20 of the false twisting machine 1A. The machine control device 5 may calculate the total value of the spare remaining amount using the information on the number of spare packages. Although the operator needs to check the spare remaining amount-related information and input it into the information management unit 110 (machine control device 5), when such input is made, individual remaining amount content information and / or total remaining amount content information that takes the spare remaining amount-related information into account can be acquired. This reduces the burden on the operator to some extent.

[0123] (4) The machine control device 5 is 3 In addition to the means shown in the variant of () or the above ( 3) may be included in the individual remaining amount information about the remaining amount of yarn Y contained in the spare package in each of the plurality of spindles 9 by means other than the means shown in the modified example. For example, the machine control device 5 may be configured to determine whether a yarn supply package Ps is attached to any package attachment unit 21. As a means for making such a determination, for example, the yarn supply unit 2 may have a plurality of attachment sensors (attachment information acquisition unit of the present invention) (not shown) that detect the presence or absence of a yarn supply package Ps in each of the plurality of package attachment units 21. The plurality of attachment sensors may be, for example, known optical sensors or known weight sensors. The machine control device 5 may acquire information (attachment information) about whether a spare package is attached to each of the plurality of yarn supply package holding units 20 by using detection results from the plurality of attachment sensors. The machine control device 5 may acquire spare remaining amount-related information for each spindle 9 based on the attachment information, and add the spare remaining amount to the individual remaining amount to acquire individual remaining amount information for each spindle 9 that takes the spare remaining amount-related information into account. The machine control device 5 may acquire information on the number of spare packages based on the attachment information and multiply the information on the number by WF to calculate the total spare remaining amount. The machine control device 5 may include information on the total spare remaining amount in the total remaining amount information. Alternatively, multiple attachment sensors may not necessarily be provided. For example, the machine control device 5 may be configured to allow an operator to input attachment information. When attaching a new yarn supply package Ps to a yarn supply package holder 20, the operator may input attachment information related to the yarn supply package holder 20 to the machine control device 5. In this case, the machine control device 5 corresponds to the attachment information acquisition unit of the present invention. The machine control device 5 may acquire information on the number of spare packages using the attachment information input by the operator and calculate the total spare remaining amount. Using the attachment information significantly reduces the burden on the operator.

[0124] (5) In the above-described embodiment, the machine control device 5 acquires and outputs information on individual winding amounts as the individual winding amount content information. However, this is not limited to this. For example, the machine control device 5 may handle a value obtained by adding the total amount of yarn contained in one or more currently stored packages PwS temporarily stored in the stocker 10a of each spindle 9 (hereinafter referred to as the temporary storage total amount) to the individual winding amount. In other words, the machine control device 5 may include information on the temporary storage total amount in the individual winding amount content information. In this case, the information on the temporary storage total amount corresponds to the total storage amount-related information of the present invention. The machine control device 5 may acquire total winding amount content information using such individual winding amount content information. Alternatively, the machine control device 5 may acquire total winding amount content information by adding the value obtained by summing the temporary storage total amounts for multiple spindles 9 to the total winding amount. This significantly reduces the burden on the operator.

[0125] (6) In the above-described embodiment, a stored package detector 42 is provided corresponding to each winding device 19. However, this is not limited to this. A stored package detector 42 does not necessarily have to be provided. In this case, the machine control device 5 may acquire information on the total temporary storage amount as follows and include it in the individual winding amount content information. For example, the machine control device 5 may be configured so that an operator can input information on the total temporary storage amount. In this case, the information on the total temporary storage amount corresponds to the total storage amount related information of the present invention. Alternatively, for example, the machine control device 5 may be configured so that an operator can input information on the number of stored packages PwS. The machine control device 5 may , protection The total value of the temporary storage total amount for the multiple weights 9 is calculated by multiplying the number of in-pipe packages PwS by the target weight described above. In this configuration, although the operator needs to look up the total storage amount related information and input it into the information management unit 110 (machine control device 5), when such input is made, individual winding amount content information and / or total winding amount content information that takes into account the total storage amount related information can be obtained. Therefore, the burden on the operator can be reduced to some extent.

[0126] (7) In the above-described embodiments, whether or not a yarn supply package switch has occurred is determined based on the detection results of the yarn detection sensor 24, which includes the first detection unit 25 and the second detection unit 26. However, this is not limited to this. For example, as shown in FIG. 8 , the yarn supply unit 2m of the false twisting machine 1m may include, in each spindle 9m, a switch detection unit 51 having a configuration different from that of the yarn detection sensor 24. The switch detection unit 51 may include, for example, a supply sensor 52 and a node sensor 53. The supply sensor 52 is configured to detect whether or not the yarn Y is being supplied from the first attachment unit 22. The node sensor 53 is configured to detect a node K that is stationary at a predetermined position. In this configuration, when the node K moves from the predetermined position and is no longer detected by the node sensor 53, it can be determined that a yarn supply package switch has occurred. Furthermore, whether the yarn Y is being supplied from the first attachment unit 22 or the second attachment unit 23 when switching the yarn supply package can be known based on the detection result by the supply sensor 52. In this way, even when the detection result of the node portion K is used, it is possible to reliably know whether the yarn Y is being supplied from the first attachment unit 22 or the second attachment unit 23. Note that the node portion sensor 53 may be configured to be able to detect a moving node portion K.

[0127] (8) In the above-described embodiments, the replacement of the yarn supply package Ps is performed by an operator. However, this is not limited to this. The replacement of the yarn supply package Ps may be performed by a creel robot (not shown). Furthermore, the collection of the winding package Pw is performed by an operator. However, this is not limited to this. The collection of the winding package Pw may be performed by a winding package conveying device (not shown).

[0128] (9) In the above-described embodiments, the information management unit 110 acquires information on the initial weight of the yarn Y included in the yarn supply package Ps as the initial amount information. However, this is not limited to this. For example, the information management unit 110 may acquire information on the initial length of the yarn Y included in the yarn supply package Ps as the initial amount information. The information management unit 110 may acquire information on the remaining weight using information on the initial length and information on the fineness.

[0129] (10) In the above-described embodiment, the information management unit 110 acquires both the individual remaining content information and the individual wound content information. However, this is not limited to this. The information management unit 110 may acquire only one of the individual remaining content information and the individual wound content information.

[0130] (11) In the above-described embodiments, the information management unit 110 acquires the total remaining amount content information using the individual remaining amount content information, and acquires the total wound amount content information using the individual wound amount content information. However, this is not limited to this. The information management unit 110 may store a program for directly calculating the total remaining amount based on the basic information described above, without using the individual remaining amount content information. In this case, the information management unit can acquire the total remaining amount content information without acquiring the individual remaining amount content information. Furthermore, the information management unit 110 may store a program for directly calculating the total wound amount based on the basic information described above, without using the individual wound amount content information. In this case, the information management unit can acquire the total wound amount content information without acquiring the individual wound amount content information.

[0131] (12) In the above-described embodiments, the yarn supply information reference time refers to the timing at which the information management unit 110 executes the process of acquiring management information for the yarn supply package Ps. The winding information reference time refers to the timing at which the information management unit 110 executes the process of acquiring management information for the winding package Pw. Additionally, or instead of this, the information management unit 110 may be configured as follows. For example, the information management unit 110 may be configured to store management information for the yarn supply package Ps and management information for the winding package Pw at any time in the past, or to acquire this information by calculation. The information management unit 110 may be configured to acquire at least a portion of the individual remaining amount content information, individual wound amount content information, total remaining amount content information, and total wound amount content information pertaining to a predetermined time in the past, in response to input by an operator. In this case, the past time input (specified) by the operator is included in the yarn supply information reference time and / or winding information reference time of the present invention. Furthermore, the yarn supply package Ps from which the yarn Y was unwound at such a yarn supply information reference time is included in the currently unwinding package of the present invention. The winding package Pw that has been formed at the winding information reference time is included in the package under formation of the present invention.

[0132] (13) In the above-described embodiments, the information management unit 110 is configured to allow the setting of the yarn supply information reference time and the winding information reference time to be selected from among a plurality of options in response to an input by an operator. However, this is not limited to this. The information management unit 110 may be configured not to have a plurality of options for the setting. For example, the information management unit 110 may be configured only to always acquire management information of the yarn supply package Ps and / or management information of the winding package Pw. Alternatively, the information management unit 110 may be configured to acquire the information only when a predetermined operation is performed. Alternatively, the information management unit 110 may be configured to acquire the information only for a reserved future time or a designated past time.

[0133] (14) In the above-described embodiment, the information management unit 110 acquires information about the unwinding speed Vu based on information about the rotation speed of the first feed roller 11. However, this is not limited to this. As another example, the machine control device 5 may store information about the rotation speed of the second feed roller 16 and information about the ratio between the rotation speed of the first feed roller 11 and the rotation speed of the second feed roller 16. The information management unit 110 may acquire information about the unwinding speed based on this information. Alternatively, the information management unit 110 may acquire information about the weight of the yarn Y unwound per unit time from the yarn supply package Ps as the unwinding unit amount information, instead of information about the unwinding speed. Such information may be input in advance to the machine control device 5 by, for example, an operator.

[0134] (15) In the above-described embodiments, the information management unit 110 has a plurality of machine control devices 5 and management devices 101, but this is not limited to this. That is, the information management unit 110 may include a computer device (not shown) other than the machine control devices 5 and management devices 101. Alternatively, the information management unit 110 may have only the machine control devices 5 or the management devices 101. That is, only one of the machine control devices 5 or the management devices 101 may acquire the necessary information.

[0135] (16) In the above-described embodiments, the information management unit 110 stores in advance initial amount information common to all yarn supply packages Ps. However, this is not limited to this. The information management unit 110 may store individual information of any yarn supply package Ps and initial amount information of the yarn supply package Ps in association with each other. In this case, the initial amounts of multiple yarn supply packages Ps may be different from each other.

[0136] (17) In the above-described embodiment, each of the plurality of yarn supply package holding units 20 is capable of holding two yarn supply packages Ps. However, this is not limited to this. Each of the plurality of yarn supply package holding units 20 may be capable of holding three or more yarn supply packages Ps.

[0137] Alternatively, each of the plurality of yarn supply package holding units 20 may be capable of holding only one yarn supply package Ps. In other words, the yarn supply unit 2 does not necessarily have to be configured to be able to supply the yarn Y without interruption.

[0138] (18) In the above-described embodiments, the winding section 4 is provided with an auto doffer 10 and a stocker 10a corresponding to each winding device 19. However, this is not limited to this. The auto doffer 10 does not necessarily have to be provided.
