Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, in manufacturing plants equipped with yarn processing facilities where processed yarn is produced, inventory is valued as needed. In this process, the asset value of the forming winding packages, which are current assets, is also assessed. For this reason, it is necessary to consider not only the total amount of yarn contained in each of the multiple forming winding packages, but also the individual winding amounts and / or their sum (total winding amount) contained in each of the multiple winding packages on which the yarn is being wound (i.e., in the process of forming). However, with conventional equipment, in order to obtain information on the winding amount of yarn for multiple forming winding packages (multiple forming packages), the operator must first visually inspect each forming package individually. In this situation, especially in recent years with the increasing emphasis on mass production, it is difficult to know the winding amount of yarn for numerous forming packages at the same time. Therefore, it is extremely difficult to appropriately obtain information on the total winding amount. Furthermore, obtaining this information may place an enormous burden on the operator.

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

The "total winding amount information" may be information about the total winding amount itself, or it may be information obtained by adding another value to the total winding amount. In this invention, the output unit outputs information about the individual winding amount and / or the total winding amount for each of the multiple processing weights. When the individual winding amount information is output, the operator can check the individual winding amounts for multiple packages being formed at a glance. Based on the individual winding amounts checked at a glance in this way, the total winding amount can be obtained by summing the individual winding amounts for multiple packages being formed. Also, when the total winding amount information is output, the total winding amount can be known in a short time. Therefore, it is possible to easily obtain information about the individual winding amount and / or the total winding amount of yarn contained in multiple packages being formed used in a manufacturing plant, and to reduce the burden on the operator regarding the acquisition of individual winding amounts and / or the total winding amount.

In this invention, it is possible to obtain individual winding quantity information and / or total winding quantity information for each room, building, or business establishment. Therefore, inventory can be valued efficiently.

[0012] The yarn processing equipment of the fourth invention is characterized in that, in any of the first to third inventions, each of the plurality of processing weights has a stocker capable of temporarily storing one or more completed packages that have been formed from the winding packages.

[0015] In this invention, although the operator needs to look up and input information related to the total storage quantity into the information management unit, when such input is made, individual winding quantity information that takes the total storage quantity information into account can be obtained. Therefore, the burden on the operator can be reduced to some extent.

[Figure 8] This is a schematic diagram of a false twisting machine relating to a modified example. [Modes for carrying out the invention]

[0031] (Outline of yarn processing equipment) Next, embodiments of the present invention will be described. The outline of the yarn processing equipment 100 according to this embodiment will be described with reference to the block diagram in Figure 1. As shown in Figure 1, the yarn processing equipment 100 has a plurality of false twisting machines 1 (yarn processing machines of the present invention) and a control device 101. The plurality of false twisting machines 1 are arranged, for example, along a predetermined longitudinal direction of the machine base (see Figure 2, etc.). Each false twisting machine 1 is configured to perform false twisting on yarn Y (see Figure 2, etc.), which is made of synthetic fibers such as polyester or nylon (polyamide fiber). Y is, for example, a multifilament yarn made of a plurality of filaments (not shown). Each false twisting machine 1 is configured to process the yarn Y supplied from the yarn feeding unit 2 by the processing unit 3 and wind it onto a winding bobbin Bw mounted on the winding unit 4 to form a winding package Pw, as will be described later. Each false twisting machine 1 is controlled by a machine base 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 centrally managing information acquired by multiple machine control devices 5. The management device 101 includes a management input unit 101a (e.g., mouse and keyboard), a management output unit 101b (e.g., display), and a management storage unit 101c (e.g., hard disk). The management device 101 and the multiple machine control devices 5 together constitute the information management unit 110 in this embodiment. Details of the information handled by the information management unit 110 will be described later.

[0033] (Overall configuration of the false twisting machine) Next, the overall configuration of the false twisting machine 1 will be explained 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 defined as the longitudinal direction of the machine base, and the left-right direction of the paper is defined as the width direction of the machine base. The direction perpendicular to both the longitudinal direction and the width direction of the machine base is defined as the up-down direction (vertical direction) where gravity acts. The direction in which the yarn Y travels is defined as the yarn travel direction. The false twisting machine 1 comprises a yarn supply unit 2 for supplying multiple yarns Y, a processing unit 3 for processing (false twisting) the multiple yarns Y supplied from the yarn supply 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 base control device 5.

[0034] The yarn feeding section 2 has a creel stand 6 that holds multiple yarn feeding packages Ps and is configured to simultaneously supply multiple yarns Y to the processing section 3. The processing section 3 is configured to unwind and process multiple yarns Y from the yarn feeding section 2. The processing section 3 is configured with the following components arranged in order from the upstream side in the yarn travel direction: a first feed roller 11, a twisting 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 in the processing section 3 are provided, for example, on each of the multiple weights 9 (see Figure 3) described later. The winding section 4 has multiple winding devices 19. Each winding device 19 winds the yarn Y, which has been false twisted in the processing section 3, onto a winding bobbin Bw to form a winding package Pw. Furthermore, the winding section 4 is provided with multiple auto doffers 10 that perform the exchange of a formed winding package Pw with a new empty winding bobbin Bw, each corresponding to one of the multiple winding devices 19.

[0035] The machine control device 5 is for controlling the components of the yarn feeding 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 storage unit 5c (see Figure 1). The machine input unit 5a has, for example, a mouse, touch panel, and / or keyboard (not shown), and is configured to be operated by an operator. The machine output unit 5b has, for example, a known display 5b1 and a known printer 5b2, and is configured to output information. The machine storage unit 5c is configured to store various information for controlling the components of the yarn feeding unit 2, the processing unit 3, and the winding unit 4. Based on the various information, the machine control device 5 controls the components of the yarn feeding unit 2, the processing unit 3, and the winding unit 4. Alternatively, the machine control device 5 may indirectly control these components through various control devices (not shown) for controlling the components of the yarn feeding unit 2, the processing unit 3, and the winding unit 4. The machine control device 5 is electrically connected to the management device 101, which is a host computer. The management device 101 can use the information acquired by the machine control device 5 to perform various decisions and / or calculations, as described later.

[0036] Each of the multiple false twisting machines 1 has a main machine base 7 and a winding table 8 that are spaced apart in the machine width direction. The main machine base 7 and the winding table 8 are provided to extend approximately the same length in the machine longitudinal direction. The main machine base 7 and the winding table 8 are arranged to face each other in the machine width direction. The false twisting machine 1 has a unit called a span, which includes one set of main machine bases 7 and winding tables 8. In one span, the devices are arranged so that false twisting can be performed simultaneously on multiple yarns Y running in a line in the machine longitudinal direction. The false twisting machine 1 spans are arranged symmetrically on the left and right sides of the paper with respect to the center line C in the machine width direction of the main machine base 7 as the axis of symmetry (the main machine base 7 is common to both the left and right spans). Multiple spans are also arranged in the machine longitudinal direction. In Figure 2, false twisting machine 1A is shown on the right side of the paper with respect to the center line C as one of the multiple false twisting machines 1. Furthermore, in Figure 2, a false twisting machine 1B, separate from false twisting machine 1A, is shown on the left side of the page along the center line C.

[0037] Furthermore, the group of components through which a single thread Y passes from the thread supply section 2 to the winding section 4 is called a "weight." In other words, each of the multiple false twisting machines 1 has the same number of weights 9 (processing weights of the present invention; see Figure 3) as the number of winding devices 19 that each false twisting machine 1 has. As an example, Figure 3 shows two weights 9 (weights 9A and 9B). Roughly speaking, the multiple weights 9 are arranged in a line along the longitudinal direction of the machine base. In terms of inclusion relationships, the false twisting machine 1 has multiple spans, and each span has multiple weights 9. The false twisting machine 1 can false twist the thread Y at the weights 9 on which the thread Y is hung.

[0038] (Yarn feeding section) The configuration of the yarn feeding unit 2 will be explained with reference to Figures 2 and 3. The creel stand 6 of the yarn feeding unit 2 has a plurality of yarn package holding units 20 (see Figure 3) provided corresponding to a plurality of weights 9. Each of the plurality of yarn package holding units 20 is configured to allow two yarn packages Ps to be attached and detached. That is, the yarn package holding unit 20 has two package mounting units 21. For the sake of explanation, one of the two package mounting units 21 will be called the first mounting unit 22 and the other the second mounting unit 23. The first mounting unit 22 and the second mounting unit 23 are each configured to allow one yarn package Ps to be attached and detached. The attachment and detachment of the yarn packages Ps to the package mounting units 21 is performed, for example, by an operator.

[0039] Each yarn supply package holding section 20 of the yarn supply section 2 is configured to supply yarn Y without interruption in the following manner. For example, as shown in Figure 3, yarn supply package PsA, which is any one of a plurality of yarn supply packages Ps, is attached to the first attachment section 22. In addition, yarn supply package PsB, which is different from yarn supply package PsA, is attached to the second attachment section 23. When yarn Y is being unwound from yarn supply package PsA, yarn supply package PsA corresponds to the unwounding package of the present invention. At this time, yarn supply package PsB corresponds to the spare package of the present invention. Furthermore, the end of yarn Y contained in yarn supply package PsA and the start end of yarn Y contained in yarn supply package PsB are knotted (connected). As a result, a knot portion K (yarn connection portion) is formed between the two yarns Y. In such a case, after yarn supply package PsA is empty, it is possible to supply yarn Y without interruption from yarn supply package PsB. Specifically, immediately after the supply of yarn Y from yarn supply package PsA ends and yarn supply package PsA becomes empty, the knot portion K is pulled downstream in the yarn travel direction (towards the winding device 19), causing yarn Y to be unwound from yarn supply package PsB. In other words, after the yarn Y has been completely unwound from the yarn supply package Ps attached to one package mounting section 21, the yarn Y begins to be unwound from the next yarn supply package Ps attached to the other package mounting section 21. For the sake of explanation, this phenomenon will be referred to as yarn supply package switching. This ensures that yarn Y is supplied without interruption. Subsequently, the empty yarn supply packages Ps (yarn bobbins Bs) are replaced with new yarn supply packages Ps, for example, by an operator.

[0040] A yarn detection sensor 24 is positioned on the downstream side of each yarn supply package holding unit 20 in the yarn travel direction. The yarn detection sensor 24 is configured to detect whether the yarn Y is supplied from the first mounting unit 22 or the second mounting unit 23. As shown in Figure 3, the yarn detection sensor 24 has a first detection unit 25 and a second detection unit 26. The first detection unit 25 is configured to detect whether or not the yarn Y is supplied from the first mounting unit 22. The second detection unit 26 is configured to detect whether or not the yarn Y is supplied from the second mounting unit 23. The first detection unit 25 and the second detection unit 26 are, for example, optical sensors that optically detect the yarn Y. For more details on the yarn detection sensor 24, see, for example, Japanese Patent Publication No. 5873105. Alternatively, the first detection unit 25 and the second detection unit 26 may be, for example, contact-type sensors.

[0041] (Processing department) The configuration of the processing section 3 will be explained with reference to Figures 2 and 3. In the following, only the part of the processing section 3 corresponding to one weight 9 will be explained.

[0042] The first feed roller 11 is configured to unwind the yarn Y from the yarn supply package Ps attached to the yarn supply unit 2 and send it to the first heating device 13. The first feed roller 11 is located upstream of the twisting guide 12 in the yarn travel direction. The conveying speed of the yarn Y by the first feed roller 11 is approximately equal to the unwinding speed Vu (see Figure 3) at which the yarn Y is unwound from the yarn supply package Ps. Information on the set value of the conveying speed of the yarn Y by the first feed roller 11 is stored in advance, for example, in the machine base control device 5. A cutter (not shown) may be provided upstream of the first feed roller 11 in the yarn travel direction. When yarn breakage occurs, the cutter cuts the yarn Y, preventing the yarn Y from becoming entangled in a rotationally driven component such as the first feed roller 11.

[0043] The twist-stopping guide 12 is configured to prevent the twist applied to the yarn Y by the false twisting device 15 from propagating upstream of the twist-stopping guide 12 in the yarn travel direction. The twist-stopping guide 12 is located downstream of the first feed roller 11 in the yarn travel direction and upstream of the first heating device 13 in the yarn travel direction.

[0044] The first heating device 13 is configured to heat the yarn Y sent from the first feed roller 11. The first heating device 13 is located downstream of the twisting guide 12 in the yarn travel direction and upstream of the cooling device 14 in the yarn travel direction. In this embodiment, for the sake of simplicity, the first heating device 13 is assumed to be configured to heat one yarn Y, but it is not limited to this. The first heating device 13 may be configured 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 located downstream of the first heating device 13 in the yarn travel direction and upstream of the false twist device 15 in the yarn travel direction. In this embodiment, for the sake of simplicity, the cooling device 14 is assumed to be configured to cool one yarn Y, but it is not limited to this. The cooling device 14 may be configured to cool multiple yarns Y simultaneously.

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

[0047] The second feed roller 16 is configured to send the yarn Y processed by the false twisting device 15 to the second heating device 17. The conveying speed of the yarn Y by the second feed roller 16 is faster than the conveying speed of the yarn Y by the first feed roller 11. As a result, the yarn Y is stretched between the first feed roller 11 and the second feed roller 16. Information on the set value of the conveying speed of the yarn Y by the second feed roller 16 is stored in advance, for example, in the machine base 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 vertically. For the sake of simplicity, the second heating device 17 is assumed to be configured to heat one yarn Y, but is not limited to this. The second heating device 17 may be configured to heat multiple yarns Y simultaneously.

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

[0050] A yarn feeler 41 is positioned downstream of the third feed roller 18 in the yarn travel direction, and upstream of the winding device 19 (described later) in the yarn travel direction. The yarn feeler 41 is configured to detect whether or not the yarn Y is traveling between the third feed roller 18 and the winding device 19 in the yarn travel direction.

[0051] In the processing unit 3 configured as described above, the yarn Y, stretched between the first feed roller 11 and the second feed roller 16, is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the twist-stopping guide 12, but not upstream of the twist-stopping guide 12 in the yarn direction. The yarn Y, which has been stretched and twisted, is heated and heat-set in the first heating device 13, and then cooled in the cooling device 14. Downstream from the false twisting device 15, the yarn Y is untwisted, but the heat-setting described above maintains the wavy false twist state of each filament. Furthermore, the yarn Y, which has been false-twisted by the false twisting device 15, is relaxed between the second feed roller 16 and the third feed roller 18, heat-set in the second heating device 17, and then guided downstream in the yarn direction. Finally, the yarn Y fed from the third feed roller 18 is wound onto the winding bobbin Bw by the winding device 19. This forms the 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 for winding the yarn Y onto the winding bobbin 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 belongs to one of a plurality of weights 9 (see Figure 3). Each winding device 19 has, for example, a pivot guide 31, a traverse device 32, a cradle 33, and a winding roller 34. The pivot guide 31 is a guide that serves as a pivot point when the yarn Y is traversed. The traverse device 32 is configured to traverse the yarn Y by means of a traverse guide 35 attached to an endless belt that is reciprocated 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 to apply contact pressure to the surface of the winding package Pw. The winding roller 34 is rotated by a motor (not shown) while in contact with the surface of the winding package Pw. As a result, the winding package Pw rotates due to frictional force, and contact pressure is applied to the surface of the winding package Pw, thereby shaping the winding package Pw. Alternatively, instead of the winding roller 34 being rotated, the winding package Pw may be directly rotated by a motor (not shown).

[0053] The auto-doffer 10 is configured to remove the winding package Pw from the winding device 19 and install an empty winding bobbin Bw onto the winding device 19. In other words, the auto-doffer 10 is configured to allow the exchange of the completed winding package Pw and the empty winding bobbin Bw in the winding section 4. The auto-doffer 10 also has a cutter (not shown) capable of cutting the yarn Y in the vicinity of the winding package Pw. The formation of the winding package Pw is completed when the running yarn Y is cut by the cutter. Here, even after the yarn 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. After the completion of the formation of the winding package Pw and until the start of winding the yarn Y onto the next winding bobbin Bw, the auto-doffer 10 has a suction (not shown) capable of sucking, capturing, and holding the running yarn Y supplied to the winding device 19. Next, until the thread Y is wound onto the winding bobbin Bw, the portion of the thread Y that has been sucked up by the suction mechanism is removed by suction. For more details on the structure of the auto doffer 10, please refer to, for example, Japanese Patent Publication No. 6-212521.

[0054] The autoduffer 10 also has a stocker 10a. The stocker 10a is configured to temporarily store the winding packages Pw (hereinafter referred to as finished packages PwC) that have been formed and removed from the winding device 19. The stocker 10a faces, for example, the space formed between the creel stand 6 and the winding table 8. Finished packages PwC that are temporarily stored in the stocker 10a (storage packages PwS) are retrieved, for example, by an operator. In this embodiment, each of the multiple weights 9 has a stocker 10a configured to temporarily store multiple finished packages PwC. The stocker 10a has a storage package detection unit 42 configured to detect the number of storage packages PwS. The storage 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 storage package PwS. The machine control device 5 acquires information on the number of packages PwS temporarily stored in the stocker 10a based on the detection results from the package detection unit 42. The packages PwS are then retrieved, for example, by an operator.

[0055] Furthermore, a thread-holding device, for example, not shown, is provided near the winding device 19. The thread-holding device is configured to hold the thread Y onto an empty winding bobbin Bw mounted on the winding device 19.

[0056] In the winding section 4 configured as described above, the yarn Y sent from the third feed roller 18 is wound onto the winding bobbin Bw by each winding device 19, forming a winding package Pw (winding process). The winding process of the yarn Y onto the winding bobbin Bw is completed when the yarn Y is cut by the cutter of the auto-doffer 10. Almost simultaneously, the yarn Y supplied to the winding device 19 is held in place by suction, and the winding package Pw is removed from the cradle 33 by the auto-doffer 10. Immediately afterward, a new empty winding bobbin Bw is mounted on the cradle 33 by the auto-doffer 10. Furthermore, the yarn Y is attached to the new winding bobbin Bw by the yarn attachment device. This makes it possible to start winding the yarn Y onto the new winding bobbin Bw. For the sake of explanation, the winding package Pw that is being formed by the winding device 19 will be referred to as the forming package PwM below.

[0057] In general, in manufacturing plants equipped with yarn processing equipment 100 where processed yarn is produced, inventory is valued as needed. At that time, the asset value of the unprocessed yarn Y, which is a current asset, is also valued. 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 and their total amounts (total remaining amount) in each of the multiple yarn supply packages Ps from which the yarn Y is being unwound (i.e., in use). However, in conventional equipment, in order 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 unwounding packages"), the operator must first visually inspect each unwounding package individually. In this situation, especially in recent years when mass production is increasingly promoted, it is difficult to know the remaining amount of yarn Y for a large number of unwounding packages at the same time. Therefore, it is extremely difficult to appropriately obtain information on the total remaining amount. Furthermore, obtaining information on the total remaining amount may place an enormous burden on the operator.

[0058] Furthermore, in such manufacturing plants, when valuing inventory, the asset value of the forming winding packages Pw, which are current assets, is also evaluated. For this reason, it is necessary to consider not only the total amount of yarn Y contained in each of the multiple forming winding packages Pw, but also the individual winding amounts of yarn Y contained in each of the multiple winding packages Pw on which the yarn Y is being wound (i.e., in the process of forming) and their total value (total winding amount). However, in conventional equipment, in order to obtain information on the winding amount of yarn Y for each of the multiple winding packages Pw (multiple forming packages PwM) in the process of forming, the operator must first visually check each forming package one by one. In this situation, in recent years when mass production is increasingly promoted, it is difficult to know the winding amount of yarn Y for a large number of forming packages at the same time. For this reason, it is extremely difficult to appropriately obtain information on the total winding amount. Moreover, obtaining information on the total winding amount may place an enormous burden on the operator.

[0059] Therefore, in order to easily obtain information on the individual remaining amount or total remaining amount of yarn Y contained in multiple unwinding packages and the individual winding amount or total winding amount of yarn Y contained in multiple forming packages PwM, and to reduce the burden on the operator in obtaining this information, the information management unit 110 performs the information processing described below. As a specific example, the information management unit 110 obtains and manages various information related to the events shown in the graphs of Figures 4(a) to (c). In the following, unless otherwise specified, the explanation will be limited to one predetermined weight 9 out of multiple weights 9.

[0060] (Specific examples of events) Before specifically describing the information acquired by the Information Management Unit 110, we will first explain the events exemplified in the graphs of Figures 4(a) to 4(c) and the times in which each event occurred, as a prerequisite to help understand the following explanation. The Information Management Unit 110 acquires information on at least some of the events shown in the graphs of Figures 4(a) to 4(c) (details will be described later). The times described here are not times predicted by any means, but rather the actual times in which each event occurs.

[0061] Figure 4(a) is a graph showing the relationship between the remaining amount of yarn Y (vertical axis) and time (horizontal axis) contained in the yarn supply package Ps (specifically, yarn supply packages Ps1 and Ps3) attached to the first mounting section 22. Figure 4(b) is a graph showing the relationship between the remaining amount of yarn Y (vertical axis) and time (horizontal axis) contained in the yarn supply package Ps (specifically, yarn supply package Ps2) attached to the second mounting section 23. Figure 4(c) is a graph showing the relationship between the amount of yarn Y wound onto the winding bobbin Bw (specifically, winding bobbins Bw1, Bw2, Bw3, Bw4, Bw5, Bw6) (vertical axis) and time (horizontal axis). In all of the graphs in Figures 4(a) to (c), the origin is the time t0 at which yarn Y begins to be wound onto winding bobbin Bw1. Furthermore, in this embodiment, the weight (initial weight) of each yarn supply package Ps when the yarn Y has not been unwound at all (i.e., when fully wound) is WF.

[0062] First, at time t0, the yarn supply package Ps1 is attached to the first attachment section 22. The yarn supply package Ps2 is attached to the second attachment section 23. The remaining weight of the yarn Y contained in the yarn supply package Ps1 is W0 (less than WF). The remaining weight of the yarn Y contained in the yarn supply package Ps2 is WF. The end of the yarn Y contained in the yarn supply package Ps1 and the beginning of the yarn Y contained in the yarn supply package Ps2 are knotted together, forming a knotted portion K.

[0063] At time t0 (time ts1), the auto-doffer 10 completes mounting the winding bobbin Bw1 onto the cradle 33, and the thread begins to be wound onto the winding bobbin Bw1. In other words, time ts1 is the winding start time when the thread Y begins to be wound onto the winding bobbin Bw1. At this time, the thread Y is unwound from the thread supply package Ps1. As time passes, the remaining amount of thread Y in the thread supply package Ps1 (remaining weight) decreases, and the amount of thread Y wound onto the winding bobbin Bw1 (winding weight) increases. At time te1, the winding process of the thread Y onto the winding bobbin Bw1 is completed when the thread Y is cut by the cutter of the auto-doffer 10. In other words, time te1 is the winding end time when the thread Y has finished being wound onto the winding bobbin Bw1 (the formation of the winding package Pw1 is completed). The winding bobbin Bw1 is wound only with yarn Y supplied from the yarn supply package Ps1. The cutting of yarn Y by the cutter, the suction capture of yarn Y by the suction device (i.e., the start of suction removal of yarn Y), and the removal of winding bobbin Bw1 (winding package Pw1) from the cradle 33 occur almost simultaneously. Next, at time ts2, immediately following time te1, the auto-doffer 10 completes the mounting of winding bobbin Bw2 onto the cradle 33, and the winding of yarn Y onto winding bobbin Bw2 begins (the winding bobbin replacement operation is completed). There is a slight time lag tL between the winding completion time for winding bobbin Bw1 (time te1) and the winding start time for winding bobbin Bw2, which will be wound with yarn Y after winding bobbin Bw1 (time ts2).

[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 end time of unwinding, when the yarn Y has finished being unwound from the yarn supply package Ps1. Simultaneously with the yarn supply package Ps1 becoming empty, at time tb1 (=time ta1), the knot portion K formed by the knotting of the yarn Y contained in yarn supply package Ps1 and the yarn Y contained in 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 start time of unwinding, when the yarn Y is first unwound from yarn supply package Ps2 (when the unwinding of yarn Y begins). Furthermore, at time te2, the winding process of yarn Y onto winding bobbin Bw2 (formation of winding package Pw2) is completed, and at time ts3, the winding process of yarn Y onto winding bobbin Bw3 is started. At time te3, the winding process of yarn Y onto winding bobbin Bw3 (formation of winding package Pw3) is completed.

[0065] Furthermore, at time ta2, after time ta1 and before the yarn supply package Ps2 becomes empty, the operator removes the yarn supply package Ps1 from the first mounting unit 22 and installs the yarn supply package Ps3 onto the first mounting unit 22. At this time, the remaining weight of the yarn supply package Ps3 is WF. Subsequently, at an appropriate timing, the operator knots the end of the yarn Y contained in the yarn supply package Ps2 and the start of the yarn Y contained in the yarn supply package Ps3, forming a knotted portion K. The operator may perform the knotting by hand. Alternatively, the operator may perform the knotting by operating a portable knotting device (not shown), for example.

[0066] A brief explanation of subsequent events follows. The events concerning the winding unit 4 are as follows: From time ts4 to time te4, yarn Y is wound onto the winding bobbin Bw4 (winding package Pw4 is formed). From time ts5 to time te5, yarn Y is wound onto the winding bobbin Bw5 (winding package Pw5 is formed). From time ts6 to time te6, yarn Y is wound onto the winding bobbin Bw6 (winding package Pw6 is formed). The events concerning the yarn feeding unit 2 are as follows: At time tb2 (=time ta3) between time ts4 and time te4, the yarn feeding package Ps2 becomes empty, and yarn Y begins to be unwound from the yarn feeding package Ps3. Then, at time tb3, the yarn feeding package Ps2 is exchanged with the yarn feeding package Ps4. At time ta4 (=time tb4), between time ts6 and time te6, the yarn supply package Ps3 becomes empty, and yarn Y begins to be unwound from yarn supply package Ps4.

[0067] (Basic information on the yarn supply package) Taking the above events into consideration, we will first explain the basic information of the yarn supply packages Ps acquired by the information management unit 110. The information management unit 110 acquires, for example, the initial quantity information, the unwinding unit quantity information, and the cumulative unwinding time information for each yarn supply package Ps as basic information of the yarn supply packages Ps. This information can be used to acquire management information for each yarn supply package Ps (details will be described later).

[0068] Initial quantity information refers to the initial amount (initial weight or initial length) of yarn Y contained in the yarn supply package Ps before the yarn Y begins to unravel. Initial quantity information is pre-set in the machine control device 5 as common information relating to all yarn supply packages Ps of all spindles 9 in one false twisting machine 1. More specifically, in this embodiment, the initial weight (i.e., WF) information and the fineness (weight per unit length) information of yarn Y are stored in the machine control device 5 as initial quantity information. The unit of weight of the yarn supply package Ps is, for example, kg. The fineness of yarn Y is denoted as F. The unit of fineness is, for example, dtex (decitex). Decitex is the weight (g) of yarn Y per 10,000 meters.

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

[0070] The cumulative unwinding time information is information regarding the cumulative value of the time (cumulative unwinding time) during which yarn Y is unwinded from the yarn supply package Ps. For convenience of explanation, the cumulative unwinding time related to the yarn supply package Ps from which yarn Y is being unwinded is called tinU. The cumulative unwinding time information is obtained as follows. During the winding process, the machine control device 5 determines, based on the detection result from the yarn detection sensor 24, whether a yarn supply package switchover has occurred, in which the yarn supply package Ps supplying yarn Y is switched. For example, referring to Figures 4(a) and (b), the event in which yarn Y from yarn supply package Ps1 has finished unwinding (unwinding completion) and yarn Y is first unwound from yarn supply package Ps2 is a yarn supply package switchover. When the state of the yarn detection sensor 24 switches from a state in which yarn Y is detected by one of the first detection unit 25 and the second detection unit 26 to a state in which 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 also acquire and store information on the unwinding start time (i.e., time ta1) when yarn Y begins to be unwound from the yarn supply package Ps2.

[0071] Subsequently, the machine control device 5 increases tinU (updates tinU) as time elapses while yarn Y is being unwound from the yarn supply package Ps2. Also, if the unwounding of yarn Y from the yarn supply package Ps2 is temporarily suspended for reasons such as yarn breakage, the machine control device 5 temporarily suspends updating tinU. In this way, the machine control device 5 acquires only the time (detection time) during which the unwounding of yarn Y from the yarn supply package Ps2 is detected by the yarn detection sensor 24 as the cumulative unwounding time (tinU). Similarly, when the unwounding of yarn Y from the yarn supply package Ps2 is complete and the unwounding of yarn Y from the yarn supply package Ps3 has begun, the machine control device 5 performs the reset process described above based on the detection result from the yarn detection sensor 24 (setting tinU to the initial time). Subsequently, the machine control device 5 updates tinU as time elapses, thereby acquiring information on the cumulative unwounding time of yarn Y unwound from the yarn supply package Ps3. In this way, the machine control device 5 can acquire cumulative unwinding time information related to any yarn supply package Ps when yarn Y is being unwinded from that yarn supply package Ps.

[0072] As described above, the information management unit 110 acquires initial quantity information, unwinding unit quantity information, and cumulative unwinding time information as basic information for the yarn supply package Ps.

[0073] (Information regarding the replacement of the yarn supply package and knotting) Furthermore, in relation to the yarn supply package switching described above, we will explain the 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. When the yarn supply package Ps attached to one of the package mounting sections 21 is empty, the operator removes the empty yarn supply package Ps from that package mounting section 21 and attaches a new yarn supply package Ps to that package mounting section 21. The operator then connects the starting end of the yarn Y contained in the new yarn supply package Ps to the ending end of the yarn Y contained in the yarn supply package Ps attached to the other package mounting section 21, forming a knot portion K. Next, the operator positions the knot portion K in a predetermined position. Furthermore, the operator inputs information indicating that the knot portion K has been positioned in a predetermined position (for convenience of explanation, this information will be called positioning information) into the machine base control device 5. The machine base control device 5 stores the positioning information when such an input operation is performed. Subsequently, when a yarn supply package change occurs, the machine control device 5 performs the reset process described above and stores information indicating that the knot portion K has moved from its predetermined position (for convenience of explanation, this information will be called movement information).

[0074] (Regarding the setting of the yarn supply information reference time) The information management unit 110 is configured to set a reference time for yarn supply information, which serves as a basis for acquiring management information for the yarn supply package Ps. In this embodiment, the reference time for yarn supply information means the time (timing) at which the information management unit 110 executes the process of acquiring management information for the yarn supply package Ps. For example, the information management unit 110 stores multiple options for setting the reference time for yarn supply information. Based on one setting selected from the multiple options by an input operation to the machine input unit 5a, the information management unit 110 determines whether or not the reference time for yarn supply information has arrived. The multiple options include, for example, "always," "at predetermined operation time," and "reserved." If "always" is selected, the information management unit 110 determines that the reference time for yarn supply information has arrived each time a predetermined first time has elapsed. The information management unit 110 may store the first time in an unchangeable state. Alternatively, the information management unit 110 may be configured to newly set and / or rewrite the first time in response to an input from the operator to the machine input unit 5a. If "At the time of 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 the first reservation time set by the operator via the machine input unit 5a arrives. The first reservation time is a time in the future from the time when the operator is performing the input operation. The information management unit 110 is configured to allow the setting of the yarn feeding information reference time to be reselected (changed) in response to the operator's input to the machine input unit 5a. Information regarding the setting of the yarn feeding information reference time corresponds to the yarn feeding setting information of the present invention.

[0075] (How to obtain management information for yarn supply packages) Next, an example of how the information management unit 110 acquires management information for the yarn supply packages Ps will be described. In this embodiment, the management information for the yarn supply packages Ps includes information on the remaining amount. The remaining amount is, for example, an estimated value of the amount (more precisely, the weight) of yarn Y contained in the yarn supply packages Ps from which yarn Y has been unwound at the yarn supply information reference time described above. When this remaining amount (remaining weight) is denoted as 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 pertaining to the yarn supply packages Ps from which yarn Y has been unwound, for each of the multiple spindles 9 contained in each of the multiple false twisting machines 1. For convenience of explanation, the remaining amount pertaining to any one spindle 9 will be called the individual remaining amount.

[0076] Wr = WF - (A × Vu × F × tinU)

[0077] The information management unit 110 may also calculate a predicted value for the length of time (remaining time) from when yarn Y is being unwound in the yarn supply package Ps at the yarn supply information reference time until the yarn Y is completely unwound. When the remaining time for the yarn supply package Ps at the yarn supply information reference time is denoted as tR, the value of tR can be calculated based on, for example, one of the following two formulas. The information management unit 110 may also calculate the remaining amount using the remaining time information after calculating the remaining time based on the lower of the two formulas.

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

[0079] (Basic information on reel packaging) Next, the basic information of the winding package Pw acquired by the information management unit 110 will be explained. The information management unit 110 acquires the following basic information for each winding package Pw: information on the thickness of the yarn Y that is processed and wound onto the winding bobbin Bw, winding speed information, and cumulative winding time information. This information can be used to acquire management information for each winding package Pw (details will be described later).

[0080] For the sake of explanation, the thickness (weight per unit length) of the processed yarn Y is referred to as Fw. The unit of thickness is dtex, the same as for fineness, i.e., the weight (g) of yarn Y per 10,000 meters. Fw is pre-set in the machine control device 5 as common information relating to all winding packages Pw of all spindles 9 in a single false twisting machine 1.

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

[0082] The cumulative winding time information is information regarding the cumulative value of the time (cumulative winding time) that the yarn Y has been wound onto the winding bobbin Bw. For the sake of explanation, the cumulative winding time for the winding bobbin Bw on which the yarn Y is wound is called tinW. The cumulative winding time information is obtained as follows: When the machine control device 5 performs the winding process onto a new empty winding bobbin Bw, it controls the auto-doffer 10 to mount the winding bobbin Bw onto the winding device 19. For example, when the machine control device 5 starts controlling the auto-doffer 10, it sets tinW to a predetermined initial time (for example, zero). Next, the machine control device 5 controls the yarn threading device (not shown) to perform yarn threading onto the winding bobbin Bw mounted on the winding device 19. When the yarn Y is detected by the yarn feeler 41 and the yarn threading operation by the yarn threading device is completed, the machine control device 5 determines that the winding process has started and begins updating tinW. In other words, after the machine control device 5 determines that the winding process has started, it increases tinW (updates tinW) as time elapses. The machine control device 5 can acquire cumulative winding time information related to any winding package Pw when that winding package Pw is being formed.

[0083] The machine control device 5 determines that a winding package Pw is complete at any weight 9 when the cumulative winding time at that weight 9 reaches a predetermined target winding time. When the machine control device 5 determines that a winding package Pw is complete, it 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] As described above, the information management unit 110 acquires information on thread thickness, winding speed, and cumulative winding time as basic information for the winding package Pw.

[0085] (Regarding the setting of the winding information reference time) The information management unit 110 is configured to set a winding information reference time, which serves as a basis for acquiring management information of the winding package Pw. In this embodiment, the winding information reference time means the time (timing) at which the information management unit 110 executes the process of acquiring management information of the winding package Pw. For example, the information management unit 110 stores multiple options for setting the winding information reference time. Based on one setting selected from the multiple options by an input operation to the machine input unit 5a, the information management unit 110 determines whether or not the winding information reference time has arrived. 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 each time a predetermined second time has elapsed. The information management unit 110 may store the second time in an unchangeable state. Alternatively, the information management unit 110 may be configured to newly set and / or rewrite the second time in response to an input from the operator to the machine input unit 5a. The second time period may be the same length as the first time period described above, or it may be a different length. If "at 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. If "reservation" is selected, the information management unit 110 determines that the winding information reference time has arrived when the second reservation time set by the operator via the machine input unit 5a arrives. The second reservation time is a time in the future from 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 it may be a different time. The information management unit 110 is configured to re-select (change) the settings related to the winding information reference time in response to the operator's input to the machine input unit 5a. The 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 allow separate setting of the yarn feeding information reference time and the winding information reference time. Alternatively, the information management unit 110 may be configured to allow setting of an "information acquisition time" which is treated as both the yarn feeding information reference time and the winding information reference time.

[0087] (How to obtain management information for rolled packages) Next, an example of how the information management unit 110 acquires management information for the winding package Pw will be described. In this embodiment, the management information for the winding package Pw includes information on the winding amount. The winding amount is the amount (more precisely, the weight) of yarn Y contained in the winding package Pw (package PwM in formation) that is formed at the winding information reference time described above. When the winding amount (winding weight) is denoted as Ww, the value of Ww can be calculated using the value of tinW at the winding information reference time, for example, based on the following formula. A is the coefficient described above. For the sake of explanation, the winding amount pertaining to any one weight 9 will be called the 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, the procedures for calculating and outputting the total remaining amount, and the procedures for calculating and outputting the total winding amount, will be explained with reference to Figures 5 to 7(b). Figure 5 is a flowchart for calculating and outputting the total remaining amount of yarn Y contained in multiple packages being unwound. Figure 6 is a flowchart for calculating and outputting the total winding amount of yarn Y contained in multiple packages PwM being formed. Figure 7(a) is an explanatory diagram showing screen S1 displaying the total remaining amount and total winding amount, etc. Figure 7(b) is an explanatory diagram showing screen S2 displaying various menus. For the sake of explanation, as an example, the machine input unit 5a has a touch panel that is positioned to overlap with the display 5b1. In the following, as a specific example, the total remaining amount and total winding amount in the false twisting machine 1A (see Figure 1) will be explained. Furthermore, the machine control device 5 that controls the false twisting machine 1A, which is part of the information management unit 110, will perform the following processing. However, it 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 now be explained. First, the machine control device 5 calculates the cumulative unwinding time at the yarn supply information reference time described above. That is, the machine control device 5 calculates the cumulative unwinding time described above for each yarn supply package Ps (i.e., packages being unwound) that is attached to the yarn supply package holding section 20 of each of the multiple spindles 9 included in the false twisting machine 1A and in which the yarn Y is being unwound (S101). Next, the machine control device 5 calculates the individual remaining amount (Wr) for each of the multiple spindles 9, for example, based on the formula described above (S102). The information on the individual remaining amount for each spindle 9 is included in the individual remaining amount information of the present invention. Hereinafter, for the sake 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 supply information reference time may differ among the multiple spindles 9. This is due to the fact that the unwinding start time may differ among multiple weights 9, and that temporary unwinding may stop at each weight 9 due to thread breakage or forced thread severance. The individual remaining amount information may be information about the individual remaining amount itself, or it 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 summing the individual remaining amounts for all of the multiple weights 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. Hereinafter, for the sake of explanation, the process of acquiring the total remaining amount content information will be referred to as the total remaining amount information acquisition process.

[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 / or performs a process to acquire total remaining amount information. The information management unit 110 performs an individual remaining amount information acquisition process for each of the partial false twisting machines 1. and Alternatively, you may perform a process to obtain total remaining amount information.

[0093] Next, the machine control device 5 displays, for example, the machine identification number assigned to the false twisting machine 1A, the individual remaining quantity information for each spindle 9, and the calculated total remaining quantity information 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 and total remaining quantities 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 quantity information or the total remaining quantity information may be displayed.

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

[0095] The output process includes, for example, the following: When the operator touches the "Print" button, the machine control device 5 controls the printer 5b2 to print the individual remaining amount and / or total remaining amount information onto a printing medium such as paper. When the operator touches the "File Output" button, the machine control device 5 generates a known CSV file (the electronic file of the present invention) containing the individual remaining amount and / or total remaining amount information. 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 performs the process of adding data containing the individual remaining amount and / or total remaining amount information 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 the individual remaining amount and / or total remaining amount information 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, for example, to a machine control device 5 that controls a false twisting machine 1 other than false twisting machine 1A (for example, false twisting machine 1B). Alternatively, the data may be transmitted to a management device 101. Alternatively, the data may be transmitted to an external computer separate from 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, mobile phone, or tablet terminal.

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

[0097] Next, the procedure for calculating and outputting the total winding amount will be explained. 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 each winding package Pw (i.e., package PwM) being formed, which is attached to the winding device 19 of each of the multiple spindles 9 included in the false twisting machine 1A and on which the yarn Y is being wound (S201). Next, the machine control device 5 calculates the individual winding amount (Ww) for each of the multiple spindles 9, for example, based on the formula described above (S202). The information on the individual winding amount for each spindle 9 is included in the individual winding amount information of the present invention. Hereinafter, for the sake 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 due to the fact that the winding start times may differ among the multiple weights 9, and that temporary winding stops may occur at each weight 9 due to thread breakage or forced thread severance.

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

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

[0101] The machine control device 5 may be configured to display information on the total remaining amount and the total winding amount simultaneously on the display 5b1, as shown in Figure 7(a). Alternatively, the machine control device 5 may be configured to allow switching between a mode in which the information on the total remaining amount is displayed on the display 5b1 and a mode in which the information on the total winding amount is displayed on the display 5b1.

[0102] Furthermore, the machine control device 5 is configured to display a menu on the display 5b1 for the operator to perform input operations. As a simple example, when the operator touches the "Menu" button displayed on screen S1 (see Figure 7(a)), the machine control device 5 displays a menu screen (screen S2) on the display 5b1 based on the input result to the machine input unit 5a (see Figure 7(b)). The machine control device 5 determines whether the operator has performed a predetermined output operation on the machine input unit 5a (S205). If an output operation has been performed (S205: Yes), the machine control device 5 executes output processing according to the input result to the machine input unit 5a. If no output operation has been performed (S205: No), the machine control device 5 terminates the series of processes.

[0103] The output process includes, for example, the following: When the operator touches the "Print" button, the machine control device 5 controls the printer 5b2 to print the individual winding amount and / or total winding amount information onto a printing medium such as paper. When the operator touches the "File Output" button, the machine control device 5 generates a known CSV file (the electronic file of the present invention) containing the individual winding amount and / or total winding amount information. 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 performs the process of adding data containing the individual winding amount and / or total winding amount information 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 the individual winding amount and / or total winding amount information 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, for example, to a machine control device 5 that controls a false twisting machine 1 other than false twisting machine 1A (for example, false twisting machine 1B). Alternatively, the data may be transmitted to a management device 101. Alternatively, the data may be transmitted to an external computer separate from 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, mobile phone, or tablet terminal.

[0104] For the sake of explanation, the process of outputting individual winding amount information will be referred to as the individual winding amount information output process. Similarly, the process of outputting total winding amount 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 false twisting machine group described above.

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

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

[0107] The configuration of the machine input unit 5a is not limited to those described above. The machine input unit 5a may, for example, have 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 overlapping a predetermined button. Of course, the machine input unit 5a may have other means for the operator to perform appropriate input operations.

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

[0109] Furthermore, in this embodiment, it is also necessary to know the total amount of yarn contained in the finished packages PwC temporarily stored in the winding unit 4. As described above, the machine control device 5 acquires information on the number of finished 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, individual winding amount information and / or total winding amount information are output by the machine base output unit 5b, etc. When at least a portion of the individual winding amount information is output, the operator can check the individual winding amounts for multiple packages PwM being formed at a glance. Based on the individual winding amounts checked at a glance in this way, the total winding amount can be obtained by summing the individual winding amounts for multiple packages PwM being formed. Also, when total winding amount information is output, the total winding amount can be known in a short time. Therefore, the individual winding amount of yarn Y contained in multiple packages PwM being formed and / Alternatively, information on the total winding amount can be easily obtained, and the individual winding amount and / Alternatively, it can reduce the operator's burden in obtaining the total winding amount. In particular, the acquisition and output of information on the total winding amount significantly reduces the operator's burden.

[0111] Furthermore, individual winding amount information output processing and / or total winding amount information output processing are performed for a predetermined false twisting machine group. This makes it possible to obtain individual winding amount information and / or total winding amount information for each room, building, or business establishment where multiple false twisting machines 1 are installed. Therefore, inventory valuation can be performed efficiently.

[0112] Furthermore, in this embodiment, it is also necessary to know the total amount of yarn contained in one or more completed packages PwC temporarily stored in the stocker. Even with this configuration, information on the individual winding amount for each of at least several packages PwM being formed and / or information on the total winding amount can be output, thus reducing the burden on the operator.

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

[0114] Furthermore, operators can obtain information on the individual winding volume and / or the total winding volume simply by looking at the printed document.

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

[0116] Furthermore, by operating an external computer, individual winding amount information and / or total winding amount information can be obtained.

[0117] Furthermore, the information management unit 110 is configured to allow operators to input winding setting information related to the setting of the winding information reference time. This allows the winding information reference time to be set according to the operator's requests.

[0118] Furthermore, the information management unit 110 is configured to allow setting a winding information reference time as any time, including in the future, based on the winding setting information. This makes it possible to obtain information on the individual winding amount and / or the total winding amount at any given time.

[0119] Next, modified examples of the above embodiments will be described. However, components having the same configuration as the above embodiments will be denoted by the same reference numerals and their descriptions will be omitted as appropriate.

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

[0121] (2) In the embodiments described above, the machine output unit 5b has a display 5b1 and a printer 5b2. However, it 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 a machine output unit 5b. The machine control device 5 may be configured to allow some kind of output device (not shown) to be temporarily connected.

[0122] (3) In the embodiments described above, the machine control device 5 acquires and outputs information on the individual remaining amount as individual remaining amount information. In addition to this, the machine control device 5 may be configured to acquire information on the remaining amount (remaining weight) of yarn Y contained in spare packages attached to each of the multiple yarn supply package holding units 20 of the false twisting machine 1A. More specifically, the machine control device 5 may be configured as follows. The machine control device 5 may be configured to allow the operator to input information on the remaining amount of yarn Y (hereinafter referred to as "reserve remaining amount") contained in spare packages attached to each of the multiple yarn supply package holding units 20 of the false twisting machine 1A. The value of the reserve remaining amount is, for example, a weight value (in 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 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 relating to multiple spindles 9. Alternatively, the machine control device 5 may obtain total remaining amount information by adding the sum of the remaining reserve amounts for multiple weights 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 package holding units 20 of the false twisting machine 1A. The machine control device 5 may use the information on the number of spare packages to calculate the total remaining reserve amount. Although the operator needs to look up the remaining reserve amount-related information and input it into the information management unit 110 (machine control device 5), when such input is made, individual remaining amount information and / or total remaining amount information that takes the remaining reserve amount-related information into account can be obtained. Therefore, the burden on the operator can be reduced to some extent.

[0123] (4) The machine control device 5 is as described above ( 3 In addition to the means shown in the modified example of ), or the above ( 3In addition to the modified example shown, the machine control device 5 may include information on the remaining amount of yarn Y contained in the spare package in each of the multiple spindles 9 in the individual remaining amount information by means other than those shown. For example, the machine control device 5 may be configured to determine whether or not a yarn supply package Ps is attached to any package mounting section 21. As a means for making such a determination, for example, the yarn supply section 2 may have multiple mounting sensors (mounting information acquisition section of the present invention) not shown that detect the presence or absence of yarn supply packages Ps in each of the multiple package mounting sections 21. The multiple mounting sensors may be, for example, known optical sensors or known weight sensors. The machine control device 5 may use the detection results from the multiple mounting sensors to acquire information (mounting information) on whether or not a spare package is attached to each of the multiple yarn supply package holding sections 20. Based on the mounting information, the machine control device 5 may acquire spare remaining amount related information for each spindle 9 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 mounting information and calculate the total remaining spare quantity by multiplying this number by WF. The machine control device 5 may also include the information on the total remaining spare quantity in the total remaining quantity information. Alternatively, multiple mounting sensors are not necessarily provided. For example, the machine control device 5 may be configured to allow the operator to input mounting information. When the operator mounts a new yarn package Ps to any yarn package holder 20, the operator may input mounting information related to the yarn package holder 20 to the machine control device 5. In this case, the machine control device 5 corresponds to the mounting information acquisition unit of the present invention. The machine control device 5 may acquire information on the number of spare packages using the mounting information input by the operator and calculate the total remaining spare quantity. By using mounting information, the burden on the operator can be greatly reduced.

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

[0125] (6) In the embodiments described above, a package detection unit 42 in storage is provided in correspondence with each winding device 19. However, this is not limited to this. The package detection unit 42 in storage is not necessarily provided. In this case, the machine control device 5 may acquire information on the total amount of temporary storage as follows and include it in the individual winding amount information. For example, the machine control device 5 may be configured to allow the operator to input information on the total amount of temporary storage. In this case, the information on the total amount of temporary storage corresponds to the total amount of storage related information of the present invention. Alternatively, for example, the machine control device 5 may be configured to allow the operator to input information on the number of packages PwS in storage. The machine control device 5 , protection By multiplying the number of pipe packages PwS by the aforementioned target weight, the total temporary storage amount for multiple weights 9 is calculated. In this configuration, although the operator needs to look up storage total 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 storage total amount-related information into account can be obtained. Therefore, the burden on the operator can be reduced to some extent.

[0126] (7) In the embodiments described above, the occurrence of a yarn supply package switch was determined based on the detection result of a yarn detection sensor 24 having a first detection unit 25 and a second detection unit 26. However, this is not limited to this. For example, as shown in Figure 8, the yarn supply unit 2m of the false twisting machine 1m may have a switch detection unit 51 in each spindle 9m that has a different configuration from the yarn detection sensor 24. The switch detection unit 51 may have, for example, a supply sensor 52 and a knot portion sensor 53. The supply sensor 52 is configured to detect whether or not yarn Y is being supplied from the first mounting unit 22. The knot portion sensor 53 is configured to detect a knot portion K that is positioned to remain stationary in a predetermined location. In such a configuration, when the knot portion K moves from the predetermined position and the knot portion K is no longer detected by the knot portion sensor 53, it can be determined that a yarn supply package switch has occurred. Furthermore, when switching yarn supply packages, it is possible to determine whether the yarn Y is supplied from the first mounting section 22 or the second mounting section 23 based on the detection results from the supply sensor 52. In this way, even when using the detection results of the knot portion K, it is possible to reliably determine whether the yarn Y is supplied from the first mounting section 22 or the second mounting section 23. Note that the knot portion sensor 53 may be configured to detect a moving knot portion K.

[0127] (8) In the embodiments described above, the replacement of the yarn supply package Ps was 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). Also, the retrieval of the winding package Pw was performed by an operator. However, this is not limited to this. The retrieval of the winding package Pw may be performed by a winding package transport device (not shown).

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

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

[0130] (11) In the embodiments described above, the information management unit 110 obtains total remaining amount information using individual remaining amount information and obtains total winding amount information using individual winding amount information. However, it 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 individual remaining amount information. In this case, the information management unit can obtain total remaining amount information without obtaining individual remaining amount information. Alternatively, the information management unit 110 may store a program for directly calculating the total winding amount based on the basic information described above without using individual winding amount information. In this case, the information management unit can obtain total winding amount information without obtaining individual winding amount information.

[0131] (12) In the embodiments described above, the yarn supply information reference time refers to the timing at which the information management unit 110 performs 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 performs the process of acquiring management information for the winding package Pw. In addition to 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 also be configured to acquire at least a portion of the individual remaining amount information, individual winding amount information, total remaining amount information, and total winding amount information related to a predetermined time in the past, in response to input by the 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 in which the yarn Y was being unwound at such a yarn supply information reference time is included in the unwounding package of the present invention. Furthermore, the winding package Pw that was formed at such a winding information reference time is included in the forming package of the present invention.

[0132] (13) In the embodiments described above, the information management unit 110 is configured to allow the operator to select settings for the yarn feeding information reference time and the winding information reference time from a plurality of options in response to input from the operator. However, it 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 to always acquire management information for the yarn feeding package Ps and / or management information for the winding package Pw. Alternatively, the information management unit 110 may be configured to acquire such information only when a predetermined operation is performed. Alternatively, the information management unit 110 may be configured to acquire such information only for a reserved future time or a specified past time.

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

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

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

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

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

[0138] (18) In the embodiments described above, the winding section 4 is provided with an auto-doffer 10 and a stocker 10a corresponding to each winding device 19. However, it is not limited to this. The auto-doffer 10 is not necessarily provided. The winding section 4 may be configured, for example, so that the completed winding package Pw can be removed from the winding device 19 and recovered by an operator.

[0139] (19) In the embodiments described above, the yarn processing equipment 100 is provided with a plurality of false twisting machines 1, but it is not limited to this. The yarn processing equipment 100 may be provided with only one false twisting machine 1. Also, the control device 101 is not required. In this case, the false twisting machine 1 corresponds to the yarn processing equipment of the present invention.

[0140] (20) The present invention may be applied to a yarn processing facility equipped with a yarn processing machine instead of the yarn processing facility 100 equipped with a false twisting machine 1. For example, the present invention may be applied to a yarn processing facility equipped with an air processing machine (yarn processing machine) as described in Japanese Patent Application Publication No. 2002-088605.
