Description

Silk thread processing machine

Technical Field

The utility model relates to a wire processing machine.

Background

Patent document 1 discloses a device (yarn processing machine) for processing a yarn unwound from a yarn supply package (described as a yarn supply tube in patent document 1) formed by winding a yarn around a yarn supply tube, and winding the yarn around a winding tube to form a wound body (winding package). The yarn processing machine is configured to support two yarn supply packages corresponding to one winding bobbin. In such a yarn processing machine, when the terminal end portion of the yarn included in one of the two yarn feeding packages and the starting end portion of the yarn included in the other yarn feeding package are knotted (connected), the yarn can be fed from the other yarn continuously after the one yarn becomes empty. Specifically, after the yarn is fed from the one yarn feeding package and is tied up, the knotted portion (yarn connecting portion) of the two yarns is pulled, and the yarn starts to be unwound from the other yarn feeding package. Thereby, the yarn can be fed without interruption.

Patent document 1: japanese patent laid-open No. 2003-526584

In the field of wire processing, various improvements have been conventionally achieved for the purpose of improvement in productivity, improvement in product quality, and the like. The present inventors have made intensive studies to develop a wire processing machine having a new added value that has not been conventionally achieved. As one of the problems, when the wire connecting portion is mixed into a certain winding package, the grade of the winding package is lowered. Therefore, the following anti-mixing process can be considered as a countermeasure. The anti-mixing process is to obtain information of the timing at which the yarn connecting portion may be mixed into the winding package by a certain method, and finish the formation of the winding package at a predetermined timing, thereby preventing the yarn connecting portion from being mixed into the winding package. However, depending on the timing of the contamination prevention process, there is a possibility that the wire connecting portion is accidentally mixed in the inner layer portion of the winding package (the portion of the wire layer included in the winding package that is radially adjacent to the winding bobbin) formed by the winding package. It is impossible to substantially remove the wire connecting portion mixed into the inner layer portion of the winding package.

Disclosure of Invention

The purpose of the present utility model is to easily remove a yarn connecting portion mixed in a winding package from the winding package.

The yarn processing machine according to claim 1 is configured to process a yarn unwound from a yarn supply package and to wind the yarn around a winding bobbin, and includes: a yarn feeding package holding unit configured to hold a 1 st yarn feeding package as the yarn feeding package and a 2 nd yarn feeding package as the yarn feeding package different from the 1 st yarn feeding package, and configured to supply a yarn without interruption when a yarn connecting portion is formed by connecting a start end portion of a yarn contained in the 1 st yarn feeding package and a terminal end portion of a yarn contained in the 2 nd yarn feeding package; an information acquisition unit configured to acquire switching information indicating occurrence of switching of yarn feeding packages from the 1 st yarn feeding package to the 2 nd yarn feeding package after unwinding of the yarn is completed and the yarn connecting portion starts to move; a winding device configured to be capable of winding a wire on the winding bobbin to form a winding package; a cutting section configured to be able to cut the wire before winding the winding bobbin; a recording unit configured to be capable of executing a mixed information recording process of recording mixed information indicating that the yarn connecting portion is mixed into the winding package; and a control unit configured to control the recording unit to execute the mixed information recording process for indicating that the wire connecting portion is mixed into the predetermined winding package which is the winding package being formed at the time of occurrence of the wire feed package switching, when it is determined that the information acquisition unit acquires the switching information, and to control the cutting unit to cut the wire at a timing at which the wire connecting portion is mixed into a surface layer portion of the predetermined winding package, thereby ending formation of the predetermined winding package in the winding device.

The surface layer portion is a portion that can be easily removed from the predetermined winding package and that has a short distance from the outer peripheral surface of the predetermined winding package in the radial direction of the predetermined winding package. In the present utility model, the thread connecting portion can be intentionally mixed into the surface layer portion of the predetermined winding package. Thus, only a small amount of the yarn contained in the surface layer portion of the predetermined wound package is unwound, and the yarn connecting portion intentionally mixed in the surface layer portion can be found and extracted. Further, by checking the recorded mix-in information, the specified winding package can be reliably distinguished from other winding packages. Thus, the yarn connecting portion mixed into the winding package can be easily removed from the winding package.

In the wire processing machine according to claim 2, in claim 1, the recording unit includes a marking unit configured to perform a marking operation of adding a mark indicating the mixed information to the winding package, and the control unit is configured to control the marking unit to perform the marking operation on the predetermined winding package when it is determined that the switching information is acquired by the information acquisition unit, thereby performing the mixed information recording process.

In the present utility model, the predetermined winding package can be easily distinguished from the winding package without any mark on the appearance.

In the wire processing machine according to claim 3, in claim 2, the marking unit includes the winding device, and the winding device includes: a rotation driving unit configured to rotate the winding package around a central axis of the winding package; and a traverse unit including a traverse guide for traversing the yarn and a guide driving unit configured to reciprocally drive the traverse guide in an axial direction of the winding package, wherein the control unit controls the rotation driving unit to rotate the winding package and controls the traverse unit to stop the traverse guide at a predetermined position in the axial direction, thereby causing the winding device to perform the marking operation.

In the present utility model, a so-called ribbon winding can be performed on a predetermined winding package. Thus, the marking operation can be performed by a simple method.

The yarn processing machine according to claim 4 is characterized in that, in any one of claims 1 to 3, the recording unit includes a storage unit configured to store information, and the blended information recording process is executed by storing the individual information of the predetermined winding package in the storage unit in association with the blended information.

In the present utility model, the predetermined winding package and the other winding package can be distinguished by checking the information stored in the storage unit.

The yarn processing machine according to claim 5 is characterized in that in any one of claims 1 to 4, the yarn processing machine includes a bobbin replacement unit configured to be capable of replacing the predetermined winding package formed in the winding device and a new winding bobbin that is the winding bobbin, and configured to be capable of winding yarn on the new winding bobbin, and the control unit is configured to control the bobbin replacement unit to replace the predetermined winding package and the new winding bobbin after the predetermined winding package is formed, and to hang yarn on the new winding bobbin, and to control the winding device to wind yarn on the new winding bobbin.

In the present utility model, even after the wire is cut by the cutting portion, the winding package can be continuously formed without stopping the operation of the wire processing machine.

The yarn processing machine according to claim 6 is characterized in that, in any one of claims 1 to 5, the information acquisition unit includes an unwinding package detection unit configured to be able to detect which of the 1 st yarn feeding package and the 2 nd yarn feeding package is unwinding the yarn, and the unwinding package detection unit acquires, as the switching information, information indicating switching from a state of unwinding the yarn from the 1 st yarn feeding package to a state of unwinding the yarn from the 2 nd yarn feeding package.

In the present utility model, since the yarn feeding package switching can be directly detected by the package-during-unwinding detecting section, the accuracy of the execution timing of the formation ending process can be improved.

The wire processing machine according to claim 7 is characterized in that, in any one of claims 1 to 5, the information acquisition unit includes a wire connection portion detection unit that can detect the wire connection portion located at a predetermined position, and the wire connection portion detection unit acquires information indicating that the wire connection portion starts to move as the switching information.

In the present utility model, since the movement of the wire connecting portion can be directly detected by the wire connecting portion detecting portion, the accuracy of the execution timing of the formation ending process can be improved.

(integral construction of false twisting machine)

Next, the overall configuration of the false twist texturing machine 1 will be described with reference to fig. 2 and 3. Fig. 2 is a side view of the false twist texturing machine 1. Fig. 3 is a schematic view of the false twist texturing machine 1 deployed along the path of the yarn Y (yarn path). The direction perpendicular to the paper surface in fig. 2 is the machine body longitudinal direction, and the left-right direction is the machine body width direction. The direction orthogonal to both the longitudinal direction and the width direction of the machine body is defined as the vertical direction (vertical direction) in which gravity acts. The direction in which the yarn Y advances is defined as the yarn advancing direction. The false twisting machine 1 includes a yarn feeding section 2 for feeding a plurality of yarns Y, a processing section 3 for processing (false twisting) the plurality of yarns Y fed from the yarn feeding section 2, a winding section 4 for winding the plurality of yarns Y processed by the processing section 3 around a winding bobbin Bw, and a machine body control device 5 (control section of the present utility model).

The yarn feeding section 2 has a creel 6 for holding a plurality of yarn feeding packages Ps, and supplies a plurality of yarns Y to the processing section 3. The processing unit 3 is configured to unwind the plurality of filaments Y from the filament supply unit 2 and process the filaments. The processing unit 3 is configured such that a 1 st godet 11, a stop yarn guide 12, a 1 st heating device 13, a cooling device 14, a false twisting device 15, a 2 nd godet 16, a 2 nd heating device 17, and a 3 rd godet 18 are disposed in this order from the upstream side in the yarn advancing direction. These components in the processing unit 3 are provided in each of a plurality of spindles 9 (see fig. 3) described later, for example. The winding section 4 has a plurality of winding devices 19. Each winding device 19 winds the yarn Y false twisted by the processing unit 3 around a winding bobbin Bw to form a winding package Pw. The winding unit 4 is provided with a plurality of automatic doffers 10 for replacing the winding package Pw and the new empty winding bobbin Bw, which are formed, corresponding to the plurality of winding devices 19, respectively.

The machine body control device 5 is configured to be able to control the components of the yarn feeding section 2, the processing section 3, and the winding section 4. The body control device 5 is, for example, a general computer device. The body control device 5 includes a body input unit 5a, a body output unit 5b, and a body storage unit 5c (storage unit of the present utility model) (see fig. 1). The body input unit 5a is configured to be operable by an operator, for example, by a touch panel and/or a keyboard, which are not shown. The body output unit 5b has, for example, a display not shown, and is configured to be able to output information. The body 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. The machine body control device 5 controls the components of the yarn feeding section 2, the processing section 3, and the winding section 4 based on various information. Alternatively, the machine body control device 5 may indirectly control the components of the wire feeding unit 2, the processing unit 3, and the winding unit 4 via various control devices (not shown) for controlling the components. The body control device 5 is electrically connected to a management device 101 as a host computer.

The false twist machine 1 includes a main body 7 and a winding table 8 arranged at intervals in the machine body width direction. The main body 7 and the winding stand 8 are provided so as to extend substantially the same length in the body length direction. The main body 7 and the winding stand 8 are disposed so as to face each other in the body width direction. The false twist machine 1 has a unit cell called a span including a set of main bodies 7 and a take-up table 8. In one span, each device is configured to be capable of simultaneously performing false twisting on a plurality of threads Y traveling in a state of being aligned in the machine body length direction. In the false twist texturing machine 1, the span is arranged symmetrically left and right on the paper surface with the center line C of the main machine body 7 in the machine body width direction as a symmetry axis (the main machine body 7 is shared by the left and right spans). In addition, a plurality of spans are arranged along the longitudinal direction of the machine body.

The group of components through which one yarn Y passes from the yarn feeding section 2 to the winding section 4 is called a "spindle". The false twist machine 1 has the same number of spindles 9 as the number of winding devices 19 (see fig. 3). Generally, the plurality of spindles 9 are arranged along the longitudinal direction of the machine body. As an inclusion, the false twist texturing machine 1 has a plurality of spans, each of which has a plurality of spindles 9. The false twisting machine 1 can perform false twisting on the yarn Y in the spindle 9 that holds the yarn Y.

(yarn feeding portion)

The structure of the yarn feeding section 2 will be described with reference to fig. 2 and 3. The creel 6 of the yarn feeding portion 2 has a plurality of yarn feeding package holding portions 20 (see fig. 3) provided in correspondence with the plurality of spindles 9, respectively. The plurality of yarn feeding package holding portions 20 are configured to be detachable from the two yarn feeding packages Ps. That is, the yarn feeding package holding portion 20 has two package mounting portions 21. For convenience of explanation, one of the two package mounting portions 21 is referred to as a 1 st mounting portion 22, and the other is referred to as a 2 nd mounting portion 23. The 1 st mounting portion 22 and the 2 nd mounting portion 23 are each configured to be detachable from one wire supply package Ps. The yarn feeding package Ps is attached to and detached from the package attaching portion 21 by an operator, for example.

The yarn feeding package holding portions 20 of the yarn feeding portion 2 are configured to be capable of continuously feeding the yarn Y as follows. For example, as shown in fig. 3, any one of the plurality of yarn feeding packages Ps, that is, the yarn feeding package Ps1, is mounted on the 1 st mounting portion 22. Further, a yarn feeding package Ps2 different from the yarn feeding package Ps1 is attached to the 2 nd attachment portion 23. Yarn Y is being unwound from yarn supply package Ps 1. The terminal end portion of the yarn Y contained in the yarn feeding package Ps1 and the starting end portion of the yarn Y contained in the yarn feeding package Ps2 are knotted (connected). Thus, a knotted portion K (yarn connecting portion) is formed between the two yarns Y. In this case, after the yarn supply package Ps1 becomes empty, the yarn Y can be supplied from the yarn supply package Ps2 without interruption. Specifically, after the supply of the yarn Y from the yarn supply package Ps1 is completed and the yarn supply package Ps1 is emptied, the knotting portion K is pulled toward the downstream side (the winding device 19 side) in the yarn advancing direction, whereby the yarn Y is unwound from the yarn supply package Ps 2. That is, after the yarn Y is unwound from the yarn supply package Ps mounted on one package mounting portion 21, the yarn Y is unwound from the next yarn supply package Ps mounted on the other package mounting portion 21. Hereinafter, for convenience of explanation, this phenomenon will be referred to as yarn feeding package switching. Thereby, the yarn Y can be fed without interruption. Thereafter, the empty yarn supply package Ps (yarn supply bobbin Bs) is replaced with a new yarn supply package Ps by an operator, for example. Further, the start end portion of the yarn feeding package Ps2 and the end portion of the new yarn feeding package Ps are knotted by an operator, for example. By repeating such steps, the yarn Y can be fed from the yarn feeding portion 2 without interruption.

A yarn detection sensor 24 (an unwinding package detecting section and an information acquiring section according to the present utility model) is disposed downstream of each yarn feeding package holding section 20 in the yarn advancing direction. The yarn detection sensor 24 is configured to be able to detect which yarn Y is being fed from the 1 st mounting portion 22 and the 2 nd mounting portion 23. As shown in fig. 3, the yarn detection sensor 24 includes a 1 st detection unit 25 and a 2 nd detection unit 26. The 1 st detecting unit 25 is configured to be able to detect whether the yarn Y is being fed from the 1 st mounting unit 22. The 2 nd detecting unit 26 is configured to be able to detect whether the yarn Y is being fed from the 2 nd mounting unit 23. The 1 st detection unit 25 and the 2 nd detection unit 26 are, for example, optical sensors that optically detect the yarn Y, respectively. For more details of the wire detection sensor 24, for example, refer to japanese patent No. 5873105. Alternatively, the 1 st detection unit 25 and the 2 nd detection unit 26 may be, for example, contact sensors.

Further, in the yarn running direction, a cutter 27 configured to be able to cut the running yarn Y is provided downstream of each yarn feeding package holding section 20 and upstream of the 1 st yarn feeding roller 11. The cutter 27 is electrically connected to the body control device 5.

(processing part)

The structure of the processing unit 3 will be described with reference to fig. 2 and 3. In the following, only the portion of the machining section 3 corresponding to one spindle 9 will be described for convenience of explanation.

The 1 st yarn feeding roller 11 is configured to unwind the yarn Y from the yarn feeding package Ps attached to the yarn feeding portion 2 and convey the yarn Y to the 1 st heating device 13. The 1 st godet 11 is disposed upstream of the yarn running direction of the anti-twist yarn guide 12. The 1 st godet 11 has a feeding speed of the yarn Y substantially equal to an unwinding speed V (see fig. 3) of the yarn Y from the yarn supply package Ps. Information on the set value of the feeding speed of the 1 st godet 11 to the yarn Y is stored in advance in the body control device 5, for example. The cutter 27 is provided on the upstream side of the 1 st godet 11 in the yarn running direction. When the yarn breakage occurs, the cutter 27 cuts the yarn Y, and thereby the yarn Y can be prevented from winding around the 1 st yarn feeding roller 11 or other rotationally driven member.

The anti-twist yarn guide 12 is configured such that the twist applied to the yarn Y by the false twisting device 15 does not propagate upstream in the yarn travelling direction of the anti-twist yarn guide 12. The anti-twist yarn guide 12 is disposed downstream of the 1 st yarn feeding roller 11 in the yarn traveling direction and upstream of the 1 st heating device 13 in the yarn traveling direction.

The 1 st heating device 13 is configured to heat the yarn Y fed from the 1 st godet 11. The 1 st heating device 13 is disposed on the downstream side of the yarn advancing direction of the anti-twist yarn guide 12 and on the upstream side of the cooling device 14 in the yarn advancing direction. In the present embodiment, it is assumed for simplicity of explanation that the 1 st heating device 13 is configured to heat one yarn Y, but the present invention is not limited thereto. The 1 st heating device 13 may be configured to be capable of heating the plurality of threads Y at the same time.

The cooling device 14 is configured to cool the yarn Y heated by the 1 st heating device 13. The cooling device 14 is disposed downstream of the 1 st heating device 13 in the yarn traveling direction and upstream of the false twisting device 15 in the yarn traveling direction. In the present embodiment, it is assumed for simplicity of explanation that the cooling device 14 is configured to cool one yarn Y, but the present invention is not limited thereto. The cooling device 14 may be configured to be capable of simultaneously cooling the plurality of yarns Y.

The false twisting device 15 is configured to twist the yarn Y. The false twisting device 15 is, for example, a so-called friction disk type false twisting device, but is not limited thereto. The false twisting device 15 is disposed on the downstream side in the yarn traveling direction of the cooling device 14 and on the upstream side in the yarn traveling direction of the 2 nd godet 16.

The 2 nd yarn feeding roller 16 is configured to feed the yarn Y processed by the false twisting device 15 to the 2 nd heating device 17. The feeding speed of the yarn Y by the 2 nd yarn feeding roller 16 is faster than the feeding speed of the yarn Y by the 1 st yarn feeding roller 11. Thereby, the yarn Y is stretched between the 1 st godet 11 and the 2 nd godet 16. Information on the set value of the feeding speed of the yarn Y by the 2 nd godet 16 is stored in advance in the body control device 5, for example.

The 2 nd heating device 17 is configured to heat the yarn Y fed from the 2 nd godet 16. The 2 nd heating device 17 extends in the vertical direction. For simplicity of explanation, it is assumed that the 2 nd heating device 17 is configured to heat one yarn Y, but the invention is not limited thereto. The 2 nd heating device 17 may be configured to be capable of heating the plurality of threads Y at the same time.

The 3 rd godet 18 is configured to feed the yarn Y heated by the 2 nd heating device 17 to the winding device 19. The 3 rd godet 18 delivers the yarn Y at a slower rate than the 2 nd godet 16 delivers the yarn Y. The yarn Y is relaxed between the 2 nd and 3 rd godets 16 and 18. Information on the set value of the feeding speed of the 3 rd godet 18 to the yarn Y is stored in advance in the body control device 5, for example.

In the processing unit 3 configured as described above, the yarn Y stretched between the 1 st godet 11 and the 2 nd godet 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the anti-twist yarn guide 12, but does not propagate to the upstream side in the yarn advancing direction of the anti-twist yarn guide 12. The yarn Y twisted while being stretched is heated by the 1 st heating device 13 and heat-set, and then cooled by the cooling device 14. The yarn Y is untwisted downstream of the false twisting device 15, but the above-described heat setting maintains the state in which each filament is false twisted in a wavy form. The yarn Y false-twisted by the false twisting device 15 is relaxed between the 2 nd godet 16 and the 3 rd godet 18, and is guided downstream in the yarn traveling direction after being heat-treated by the 2 nd heating device 17. Finally, the yarn Y fed from the 3 rd supply roller 18 is wound around the winding bobbin Bw by the winding device 19. Thereby, the winding package Pw is formed.

(winding portion)

The structure of the winding unit 4 will be described with reference to fig. 2 and 3. The winding unit 4 includes a plurality of winding devices 19 (marking units of the present utility model) and a plurality of automatic doffers 10 (see fig. 2, bobbin replacing units of the present utility model) provided in correspondence with the winding devices 19. The plurality of winding devices 19 are provided one for each of the plurality of spindles 9 (see fig. 3). Each winding device 19 is configured to wind the yarn Y around the winding bobbin Bw. Each winding device 19 includes, for example, a fulcrum guide 31, a traversing device 32 (traversing portion of the present utility model), a cradle 33, and a winding roller 34. The fulcrum guide 31 is a guide that serves as a fulcrum when the wire Y is traversed. The traverse device 32 is configured to traverse the yarn Y by a traverse guide 35 attached to an endless belt reciprocally driven by a motor 36 (a guide driving unit of the present utility model), for example. That is, the traverse device 32 is configured to reciprocate the traverse guide 35 in the axial direction of the winding bobbin Bw (in other words, in the axial direction of the winding package Pw). The cradle 33 is configured to rotatably support a winding bobbin Bw (winding package Pw) around a central axis of the winding package Pw. The winding roller 34 is configured to rotate the winding package Pw about the central axis and to apply a contact pressure to the surface (outer peripheral surface) of the winding package Pw. The winding roller 34 is rotationally driven by a motor 37 (a rotation driving unit of the present utility model) in a state of being in contact with the surface of the winding package Pw, for example. Thereby, the winding package Pw is driven to rotate by friction force, and the shape of the winding package Pw is adjusted by applying contact pressure to the surface of the winding package Pw. Instead of the winding roller 34 being rotationally driven, the winding package Pw may be directly rotationally driven by a motor, not shown.

The automatic doffer 10 is configured to remove the winding package Pw from the winding device 19, and to mount an empty winding bobbin Bw to the winding device 19. In other words, the automatic doffer 10 is configured to be capable of replacing the winding package Pw after completion of formation and the empty winding bobbin Bw in the winding unit 4. The automatic doffer 10 has a cutter, not shown, capable of cutting the yarn Y in the vicinity of the winding package Pw. The advancing yarn Y is cut by the cutter, and the formation of the winding package Pw ends. Even after the yarn cutting by the cutter, the yarn Y continues to be unwound from the yarn supply package Ps at a speed substantially equal to that at the time of winding onto the winding bobbin Bw, and is supplied to the winding device 19 side. The automatic doffer 10 has an aspirator, not shown, which is capable of attracting and holding the advancing yarn Y supplied to the winding device 19 after completion of formation of a winding package Pw until starting winding of the yarn Y onto the next winding bobbin Bw. During the period before the yarn Y is hooked to the winding bobbin Bw on which the yarn Y is wound next, the portion of the yarn Y attracted by the aspirator is removed by aspiration. The automatic doffer 10 is configured to hook the yarn Y onto an empty winding bobbin Bw attached to the winding device 19. The automatic doffer 10 includes a cutting section of the present utility model. The automatic doffer 10 corresponds to a bobbin replacing section of the present utility model. For more details of the structure of the automatic doffer 10, for example, refer to japanese patent application laid-open No. 6-212521.

In the winding unit 4 configured as described above, the yarn Y fed from the 3 rd yarn feeding roller 18 is wound on the winding bobbin Bw by each winding device 19, and a winding package Pw is formed (winding process). The yarn Y is cut by the cutter of the automatic doffer 10, and the winding process of the yarn Y onto the winding bobbin Bw is completed. Almost simultaneously, the yarn Y supplied to the winding device 19 is sucked and held by the suction device, and the formed winding package Pw is removed from the cradle 33 by the automatic doffer 10. Immediately after this, a new empty winding bobbin Bw is mounted on the cradle 33 by the automatic doffer 10, and the yarn Y is hooked to the new winding bobbin Bw. This enables the yarn Y to start to be wound onto the new winding bobbin Bw.

(calculation of residual amount)

The body control device 5 is configured to be able to perform calculation of the remaining amount of the yarn Y (hereinafter referred to as remaining amount calculation) included in the yarn supply package Ps (hereinafter referred to as package under unwinding) that is unwinding the yarn Y at a predetermined reference timing. In the present embodiment, the reference time refers to the current time at which the remaining amount calculation is performed. The machine body control device 5 is configured to be able to calculate the remaining amount of the yarn Y contained in the package during unwinding at a reference time using initial amount information, unwinding unit amount information, and accumulated time information, which will be described later. Hereinafter, for convenience of explanation, the initial amount information, the unwinding unit amount information, and the cumulative time information are collectively referred to as basic information.

The initial amount information is information on an initial amount (initial weight or initial length) of the yarn Y contained in the yarn supply package Ps before the yarn Y starts to be unwound. The initial amount information is set in advance in the machine body control device 5 as common information on all the yarn feeding packages Ps of all the spindles 9 of one false twist machine 1, for example. As more specific information, in the present embodiment, the information of the initial weight WF and the information of the fineness (weight per unit length) of the yarn Y are stored as initial amount information in the body control device 5. The weight of the yarn-feeding package Ps is, for example, kg. The fineness of the yarn Y was F. The unit of fineness is dtex, for example. Dtex is the weight (g) of yarn Y per 10000 meters.

The unwinding unit amount information is information on the amount of yarn Y unwound from the yarn supply package Ps per unit time. The unwinding unit amount information is, for example, the information of the above-described unwinding speed V. In the present embodiment, for convenience of explanation, it is assumed that the unwinding speed V in the winding process is substantially constant. The unwinding speed is in m/min, for example. The unwinding unit amount information is preset in the machine body control device 5 as common information for all spindles 9 of one false twist machine 1, for example. The machine body control device 5 obtains information on the unwinding speed V based on information on a set value of the rotational speed of the 1 st godet 11, for example.

The accumulated time information is information on an accumulated value (accumulated time) of the time when the yarn Y is unwound from the yarn supply package Ps. For convenience of explanation, the accumulated time associated with the yarn supply package Ps that is unwinding the yarn Y will be referred to as tin. The integrated time information is acquired as follows. First, for example, when unwinding the yarn Y from the yarn supply package Ps1 (see fig. 3), the yarn detection sensor 24 detects the start of unwinding the yarn Y in the 1 st mounting portion 22. At this time, the body control device 5 sets tin to a predetermined initial time (reset process). The initial time is, for example, zero. Thereafter, when unwinding the yarn Y from the yarn supply package Ps, the body control device 5 increases (updates) the yarn tin according to the lapse of time. When the unwinding of the yarn Y from the yarn supply package Ps is temporarily stopped (in other words, a stop time occurs) due to, for example, a yarn break, the body control device 5 temporarily stops the update of tin. In this way, the machine control device 5 obtains only the time (detection time) when the yarn detection sensor 24 detects that the yarn Y is unwound from the yarn supply package Ps as the integrated time (tin). The machine control device 5 can acquire accumulated time information on any yarn supply package Ps when unwinding the yarn Y from the yarn supply package Ps.

In the winding process, the body control device 5 determines whether or not the yarn feeding package Ps that is feeding the yarn Y is switched based on the detection result of the yarn detection sensor 24. For example, referring to fig. 3, the phenomenon in which the yarn Y is unwound from the yarn supply package Ps1 (unwinding is completed) and the yarn Y is first unwound from the yarn supply package Ps2 is switched to the yarn supply package. When the state of the yarn detecting sensor 24 is switched from the state in which the yarn Y is detected by one of the 1 st detecting portion 25 and the 2 nd detecting portion 26 to the state in which the yarn Y is detected by the other of the 1 st detecting portion 25 and the 2 nd detecting portion 26, the machine body control device 5 determines that the yarn feeding package switching has occurred. In other words, the yarn detecting sensor 24 acquires information indicating that the yarn package switching has occurred (hereinafter referred to as switching information). When the machine body control device 5 determines that the yarn feeding package switching has occurred, it performs the above-described reset processing and sets tin to a predetermined initial time.

As described above, the machine body control device 5 generates (in other words, acquires) the initial amount information, the unwinding unit amount information, and the integrated time information as basic information by calculation.

When the remaining amount of the yarn Y contained in the package unwound at the reference time is WR, the body control device 5 calculates the remaining amount based on the following equation by using the basic information. In the expression, "1000" and "10000" are coefficients for unifying the units of the numerical values of both sides to "kg".

WR＝WF-(V×F/10000)×tin/1000

When the ratio of the remaining amount of the yarn Y contained in the package under unwinding to the initial amount (hereinafter referred to as the remaining amount ratio) is R, the machine body control device 5 can calculate the remaining amount ratio based on the following equation. The body control device 5 may calculate the percentage of WR to WF (remaining percentage) as the remaining percentage.

R＝WR/WF

Alternatively, the body control device 5 may calculate the remaining amount ratio using only the basic information without using WR.

When the remaining time during which the yarn Y can be supplied from the unwinding package is set to tR, the machine body control device 5 may estimate tR based on the following equation, for example. tR is in units of "min".

tR＝WF×1000/(V×F/10000)-tin

In the field of wire processing, various improvements have been conventionally achieved for the purpose of improvement in productivity, improvement in product quality, and the like. The present inventors have made intensive studies to develop a yarn processing device and a yarn processing machine having new added values that have not been conventionally achieved. As one of the problems, when the knotting portion K is mixed into a certain winding package Pw, the grade of the winding package Pw is lowered. Therefore, the following anti-mixing process can be considered as a countermeasure. The anti-contamination process is to obtain information of the timing at which the knotted portion K may be mixed into the winding package Pw by some method, and to terminate the formation of the winding package Pw at a predetermined timing, thereby avoiding the knotted portion K from being mixed into the winding package. However, depending on the timing of the contamination prevention process, the knotting portion K may be accidentally mixed in the inner layer portion of the winding package Pw formed by following the winding package Pw (a portion of the yarn layer included in the winding package Pw that is radially adjacent to the winding bobbin Bw). It is impossible to substantially remove the knotted portion K mixed into the inner layer portion of the winding package Pw.

Therefore, in the present embodiment, the body control device 5 performs control and information processing described later so that the knotted portion K mixed in the winding package Pw can be easily removed. In the following, unless otherwise specified, the present invention will be described with reference to one predetermined spindle 9 among the plurality of spindles 9.

(constitution for processing at the time of switching occurrence)

The machine body control device 5 is configured to be able to set in advance the content of the process when the yarn package switching occurs (hereinafter, the process when the switching occurs). The details of the processing at the time of occurrence of the handover will be described later. The configuration for the processing at the time of occurrence of the handover will be described with reference to fig. 4. Fig. 4 is an explanatory view showing a selection screen of the processing mode of the false twist processing machine 1. For convenience of explanation, a display is provided as the body output unit 5b, and a touch panel (see fig. 4) is provided as the body input unit 5a so as to overlap the display. However, the configurations of the body input unit 5a and the body output unit 5b are not limited thereto.

The body control device 5 stores information of a plurality of options handled when the switching occurs in the body storage unit 5c. The body control device 5 is configured to cause the body output unit 5b to display, for example, an option of processing when the switching occurs (see screen S1 of fig. 4). The body control device 5 is configured to be able to set the content of the processing at the time of occurrence of the switching in advance based on the input of the operator to the body input unit 5 a. For example, on the upper part of the screen S1, "no", "winding bobbin replacement", and "thread cutting" are displayed as options. "none" means that no special processing is performed even if a yarn feed package switching occurs. The "winding bobbin replacement" means that when the yarn supply package is changed, the winding bobbin Bw is replaced in accordance with the procedure described later. The "yarn cutting" is to cut the advancing yarn Y by the cutter 27 in accordance with the procedure described later when the yarn feeding package switching occurs. For convenience of the following description, the options are arranged in this order, but the order of the options is not limited to this.

(case where the processing is not performed when the handover occurs)

As a reference for understanding the following description, the unwinding of the yarn Y from each yarn supply package Ps and the formation of each winding package Pw in the case where the switching occurrence time process is not performed (the case where the above "none" is selected) will be described with reference to fig. 5 (a) to (c). Fig. 5 (a) to (c) are graphs showing the relationship between the yarn amount and the time in the conventional processing mode in which the processing is not performed at the time of occurrence of the switching. More specifically, fig. 5 a is a graph showing the relationship between the remaining amount (vertical axis) of the yarn Y and the time (horizontal axis) included in the yarn supply package Ps (specifically, the yarn supply packages Ps1 and Ps 3) mounted on the 1 st mounting portion 22. Fig. 5 b is a graph showing a relationship between the remaining amount (vertical axis) of the yarn Y contained in the yarn supply package Ps (specifically, the yarn supply package Ps 2) mounted on the 2 nd mounting portion 23 and the time (horizontal axis). Fig. 5 c is a graph showing a relationship between the winding amount (vertical axis) and the time (horizontal axis) of the yarn Y to the winding bobbin Bw (specifically, winding bobbins Bw1, bw2, bw3, bw4, bw 5). In any of the graphs (a) to (c) of fig. 5, the point of time t0 when the yarn Y is first unwound from the yarn supply package Ps1 is the origin. In the present embodiment, the weight (initial weight) of each yarn-feeding package Ps in a state where the yarn Y is not unwound from each yarn-feeding package Ps at a time (i.e., a full-wound state) is WF.

First, before time t0, the 1 st mounting portion 22 is mounted with the full-wound yarn feeding package Ps1. The yarn Y contained in the yarn package Ps1 has an initial weight WF. Before time t0, the full-wound yarn feeding package Ps2 is similarly mounted to the 2 nd mounting portion 23. The terminal end portion of the yarn Y contained in the yarn feeding package Ps1 and the starting end portion of the yarn Y contained in the yarn feeding package Ps2 are knotted, and a knotted portion K is formed. At time t0, yarn hanging is started to each part of the predetermined spindle 9. At the same time, at time t0, unwinding of yarn Y from full-reel yarn supply package Ps1 starts. After that, at a time ts1 immediately after the time t0, the yarn hanging on the winding bobbin Bw1 attached to the winding device 19 is completed, and the winding of the yarn Y on the winding bobbin Bw1 is started. Further, the yarn Y is sucked and caught by the suction device of the automatic doffer 10 from the start of unwinding the yarn Y from the yarn supply package Ps1 until the completion of the yarn hanging on the winding bobbin Bw 1. In the present embodiment, the unwinding speed of the yarn Y when the yarn is wound is substantially equal to the unwinding speed (V) when the yarn Y is wound around the winding bobbin Bw.

As time passes, the remaining amount (residual weight) of the yarn Y contained in the yarn supply package Ps1 decreases, and the winding amount (winding weight) of the yarn Y wound around the winding bobbin Bw1 increases. At time te1, the yarn Y is cut by the cutter of the automatic doffer 10, and the winding process of the yarn Y onto the winding bobbin Bw1 is ended. That is, the time te1 is a winding end time at which the winding of the yarn Y onto the winding bobbin Bw1 ends (the formation of the winding package Pw1 ends). Only the yarn Y supplied from the yarn supply package Ps1 is wound around the winding bobbin Bw 1. The cutting of the wire Y by the cutter, the suction catching of the wire Y by the suction device (i.e., the start of suction removal of the wire Y), and the removal of the winding bobbin Bw1 (winding package Pw 1) from the cradle 33 are performed almost simultaneously. Next, at a time ts2 immediately after the time te1, the automatic doffer 10 completes the installation of the winding bobbin Bw2 to the cradle 33, and starts the winding process of the yarn Y to the winding bobbin Bw2 (completion of the winding bobbin replacement operation). A slight time lag tL exists between the winding end time (time te 1) of the winding bobbin Bw1 and the winding start time (time ts 2) of the winding bobbin Bw2 of the yarn Y wound next to the winding bobbin Bw1 (see fig. 5 (c)). As described above, when the winding bobbin Bw is replaced, the yarn Y is unwound from the yarn supply package Ps at a speed substantially equal to that when the yarn is wound around the winding bobbin Bw. Further, the winding process of the yarn Y onto the winding bobbin Bw2 (formation of the winding package Pw 2) is ended at time te2, and the winding process of the yarn Y onto the winding bobbin Bw3 is started at time ts 3.

At a time ta1 (see fig. 5 (a)) after the time ts3, the yarn feeding package Ps1 mounted on the 1 st mounting portion 22 becomes empty. That is, the time ta1 is the unwinding end time at which the yarn Y is unwound from the yarn supply package Ps 1. At the same time as the yarn feeding package Ps1 is emptied, the knotted portion K formed by knotting the yarn Y contained in the yarn feeding package Ps1 and the yarn Y contained in the yarn feeding package Ps2 is pulled toward the winding device 19 at time tb1 (=time ta 1). Thereby, unwinding of the yarn Y from the yarn supply package Ps2 mounted on the 2 nd mounting portion 23 is started. That is, the time tb1 is the unwinding start time at which the yarn Y is first unwound from the yarn supply package Ps2 (the yarn Y starts to be unwound). Thereafter, the winding process of the yarn Y onto the winding bobbin Bw3 (formation of the winding package Pw 3) is ended at time te 3. Both the yarn Y unwound from the yarn supply package Ps1 and the yarn Y unwound from the yarn supply package Ps2 are wound around the winding bobbin Bw 3. The winding package Pw3 includes a knotted portion K. Thereafter, at time ts4, the winding process of the yarn Y onto the winding bobbin Bw4 is started. At time te4, the winding process of the yarn Y onto the winding bobbin Bw4 (formation of the winding package Pw 4) is ended. Only the yarn Y unwound from the yarn supply package Ps2 is wound around the winding bobbin Bw 4.

Further, after the time ta1 and before the yarn feeding package Ps2 becomes empty (for example, the time ta 2), the operator removes the empty yarn feeding package Ps1 from the 1 st mounting portion 22 and mounts a new full-wound yarn feeding package Ps3 on the 1 st mounting portion 22 (yarn feeding package replacement operation). The remaining weight of the yarn-feeding package Ps3 at this time is WF. Thereafter, at an appropriate timing, the operator knots (connects) the terminal end portion of the yarn Y contained in the yarn feeding package Ps2 and the starting end portion of the yarn Y contained in the yarn feeding package Ps3 to form a knot K (see fig. 3). The operator can perform the knotting work (the joining work) by hand. Alternatively, the operator may perform the knotting operation by operating a portable knotting device, not shown, for example.

Thereafter, the yarn Y is wound onto the winding bobbin Bw5 from the time ts5 to the time te5 (the winding package Pw5 is formed). At time tb2 between time ts5 and time te5, the yarn package Ps2 attached to the 2 nd attachment portion 23 is empty. At the same time as the yarn supply package Ps2 becomes empty, unwinding of the yarn Y from the yarn supply package Ps3 mounted on the 1 st mounting portion 22 starts at time ta3 (=time tb 2).

When the switching occurrence time processing is not performed, the yarn Y is unwound from each yarn supply package Ps as described above, and each winding package Pw is formed.

(step of changing winding tube when switching occurs)

Next, a replacement step of the winding bobbin Bw when "winding bobbin replacement" is selected as a mode of processing at the time of occurrence of the switching will be described with reference to fig. 6 to 8 (b). Fig. 6 is a flowchart showing a step of replacing the winding bobbin Bw when the yarn supply package switching occurs. Fig. 7 (a) to (c) are graphs showing the relationship between the amount of yarn and the time in the process mode of winding bobbin replacement. Fig. 7 (a) is a graph showing the relationship between the remaining amount (vertical axis) of the yarn Y contained in the yarn feeding package Ps mounted on the 1 st mounting portion 22 and the time (horizontal axis) as in fig. 5 (a). Fig. 7 b is a graph showing the relationship between the remaining amount (vertical axis) of the yarn Y contained in the yarn feeding package Ps mounted on the 2 nd mounting portion 23 and the time (horizontal axis) similarly to fig. 5 b. Fig. 7 c is a graph showing the relationship between the winding amount (vertical axis) of the yarn Y on the winding bobbin Bw and the time (horizontal axis) similarly to fig. 5 c. Fig. 8 (a) is a schematic diagram showing the winding package Pw. Fig. 8 (b) is an explanatory diagram showing information about the grade of the winding package Pw. Fig. 8 (b) shows, for example, a screen S2 related to information on the winding package Pw displayed on the body output unit 5 b.

As the initial state, for example, the 1 st mounting portion 22 is provided with the yarn feeding package Ps1 and the 2 nd mounting portion 23 is provided with the yarn feeding package Ps2, similarly to the case of the "processing when no switching occurs" described above. Further, the yarn Y unwound from the yarn supply package Ps1 is processed by the processing unit 3, and wound around the winding bobbin Bw1. The yarn supply package Ps1 corresponds to the 1 st yarn supply package of the present utility model. The yarn supply package Ps2 corresponds to the 2 nd yarn supply package of the present utility model.

The machine body control device 5 determines whether or not information indicating that the yarn package switching has occurred (i.e., switching information) is detected (acquired) by the yarn detecting sensor 24 during the winding process. Thereby, the body control device 5 determines whether or not the yarn feeding package switching has occurred (S101). When the yarn feeding package switching does not occur (S101: no), the machine body control device 5 continues the formation of the winding package Pw. In this example, the winding packages Pw1 and Pw2 are formed in this order as in the case of the process when the switching is not performed. The machine body control device 5 evaluates the winding packages Pw1 and Pw2 as winding packages Pw of high grade (for example, "a" described with reference to fig. 8 (b)), and stores individual information (ID "with reference to fig. 8 (b)) of these winding packages Pw in association with the grade, respectively.

When it is determined that the yarn feeding package switching has occurred (S101: YES), the machine body control device 5 controls the winding device 19, and performs the following marking operation on the winding package Pw being formed (S102). As an example, when the yarn supply package switching occurs, the yarn Y is wound onto the winding bobbin Bw3 to form the winding package Pw3a (see fig. 7 (c)). The winding package Pw3a being formed by the winding device 19 at the time of the yarn feeding package switching corresponds to a predetermined winding package of the present utility model. When it is determined that the yarn feeding package switching has occurred, the body control device 5 controls the motor 37 (see fig. 3) to rotate the winding package Pw3a, and controls the motor 36 to stop the traverse guide 35 at a predetermined position in the axial direction of the winding package Pw3 a. Thus, the winding package Pw3a is subjected to so-called ribbon winding, and a mark M1 is formed on the winding package Pw3a (see fig. 8 (a)). The symbol M1 is a mark indicating that the knotted portion K is mixed into the winding package Pw3 a. As described above, the winding device 19 performs the operation (marking operation) for adding the mark M1 to the winding package Pw (i.e., marking the winding package Pw).

In this way, the winding device 19 is configured to be able to perform a recording process (mixed information recording process) of mixed information indicating that the knotted portion K is mixed into the winding package Pw3a (predetermined winding package). The winding device 19 is included in the recording section of the present utility model. The mark M1 is included in the mixing information of the present utility model. The marking operation is included in the mixed information recording process of the present utility model.

Further, the body control device 5 controls the automatic doffer 10 to cut the advancing yarn Y at a predetermined timing when the knotted portion K is mixed into the surface layer portion of the winding package Pw3a, and ends the formation of the winding package Pw3a (formation end process S103). In this case, the automatic doffer 10 also corresponds to the cutting section of the present utility model. The surface layer portion is a portion that can be easily removed from the winding package Pw3a and has a short distance between the radial direction of the winding package Pw3a and the outer peripheral surface of the winding package Pw3 a. For example, a portion within 2mm from the outer peripheral surface of the winding package Pw3a in the radial direction of the winding package Pw3a is a surface layer portion. The portion where the mark M1 is formed is also included in the surface layer portion. The predetermined timing may be, for example, substantially the same as the timing at which the machine body control device 5 determines that the yarn feeding package switching has occurred. Alternatively, the predetermined timing may be when a predetermined time has elapsed since the machine body control device 5 determined that the yarn feeding package switching has occurred. In this case, the body control device 5 may store the set value for the predetermined time in advance. The body control device 5 may be configured to allow an operator to input a set value for the predetermined time. Alternatively, the machine body control device 5 may be configured to store a set value of the length of the yarn path in advance and calculate the predetermined time based on information such as the length of the yarn path and the unwinding speed.

Thereafter, the machine body control device 5 controls the automatic doffer 10 to replace the winding package Pw3a and a new winding bobbin Bw4 (S104). Further, the machine body control device 5 controls the automatic doffer 10 to hang the yarn on the new winding bobbin Bw 4. The body control device 5 evaluates the winding package Pw3a as a winding package Pw of a lower grade (for example, "B" described with reference to fig. 8B) than the winding packages Pw1 and Pw2, for example, and stores the individual information of the winding package Pw3a in association with the grade. The body control device 5 also stores the individual information of the winding package Pw3a in the body storage unit 5c in association with information indicating that the knotted portion K is intentionally mixed in the surface layer portion of the winding package Pw3a (for example, "the knotted portion is mixed in the surface layer" described with reference to fig. 8 (b)). This information is included in the mixing information of the present utility model. The process of storing this information (recording process) is included in the mixed information recording process of the present utility model. At this time, the body control device 5 functions as a recording unit of the present utility model.

After that, the body control device 5 controls the winding device 19 to start winding the yarn Y on the winding bobbin Bw 4. Thereby, the yarn Y is wound around the winding bobbin Bw4 to form the winding package Pw4. The winding package Pw4 is formed into a winding package Pw having a higher grade like the winding packages Pw1 and Pw2 (see fig. 8 b). The explanation about further subsequent processes is omitted.

(concerning thread cutting)

Next, a process when the "thread cutting" is selected as a mode of the process at the time of switching occurrence will be described. In this case, when it is determined that the yarn feeding package switching has occurred during the formation of the winding package Pw3a, the machine body control device 5 causes the winding device 19 to perform the marking operation. Thereafter, the body control device 5 controls the cutter 27 to cut the advancing yarn Y at a predetermined timing when the knotted portion K is mixed into the surface layer portion of the winding package Pw3a, and ends the formation of the winding package Pw3a (formation end process). At the same time, the machine body control device 5 controls each part of the spindle 9 to stop the spindle 9. The body control device 5 may store the individual information of the winding package Pw3a and the contamination information in the body storage unit 5c in association with each other. In order to re-operate the spindle 9, it is necessary to thread each part of the spindle 9. When "thread cutting" is selected as the mode of the process at the time of switching occurrence, the cutter 27 corresponds to the cutting section of the present utility model.

As described above, the knotted portion K can be intentionally mixed into the surface layer portion of the winding package Pw3a (predetermined winding package). Thus, the knotted portion K intentionally mixed into the surface layer portion can be found and extracted only by unwinding the small amount of yarn Y included in the surface layer portion of the wound package Pw3 a. Further, by checking the result (i.e., the mixing information) of the recording process performed by the recording unit (in the present embodiment, the winding device 19 and/or the machine body control device 5), the winding package Pw3a can be reliably distinguished from other winding packages Pw. Thus, the knotted portion K mixed in the winding package Pw3a can be easily removed from the winding package Pw3 a.

The body control device 5 controls the winding device 19 to perform a marking operation on a predetermined winding package. This makes it possible to easily distinguish the predetermined winding package from the winding package Pw without any mark on the external appearance.

The body control device 5 also causes the winding device 19 to perform a marking operation. Thereby, the winding package Pw3a can be wound in a ribbon shape. Thus, the marking operation can be performed by a simple method.

The body control device 5 further includes a body storage unit 5c, and the body storage unit 5c is configured to be capable of storing individual information defining the wound package in association with the contamination information. By checking the information stored in the body storage unit 5c, it is possible to distinguish between the predetermined winding package and the other winding package Pw.

In addition, when the automatic doffer 10 functions as the cutting section of the present utility model, the following effects can be obtained. That is, when the yarn feeding package switching occurs, the body control device 5 controls the automatic doffer 10 to replace the winding package Pw3a and the new winding bobbin Bw4, and controls the winding device 19 to start winding the yarn Y on the winding bobbin Bw 4. Thus, even after the yarn Y is cut by the automatic doffer 10, the winding package Pw can be continuously formed without stopping the operation of the spindle 9.

Further, the wire detection sensor 24 acquires switching information. This allows the yarn feeding package switching to be directly detected, and thus improves the accuracy of the execution timing of the formation ending process.

Next, a modified example in which the above embodiment is modified will be described. However, the same reference numerals are given to the portions having the same configurations as those of the above-described embodiments, and the description thereof will be omitted as appropriate.

(1) In the above embodiment, the machine body control device 5 stores information of "no", "winding bobbin replacement", and "thread cutting" as options of the process at the time of occurrence of the switching. However, the present invention is not limited thereto. The machine body control device 5 may store only one of the information of "winding bobbin replacement" and "thread cutting" as the information of the option. Alternatively, the machine body control device 5 may be configured to be able to execute only the "winding bobbin replacement" or the "thread cutting" process mode as the control mode of the process at the time of switching occurrence.

(2) In the previous embodiment, the body control device 5 causes the winding device 19 to perform the marking operation. However, the present invention is not limited thereto. A marking device (marking unit) not shown, which can perform a marking operation, may be provided instead of the winding device 19. The marking device may be configured to color the yarn Y immediately before winding the winding bobbin Bw in counter rotation, for example. The marking device may be configured to spray or spray a liquid such as ink toward the yarn Y, for example.

(3) In the above embodiment, the body control device 5 stores the individual information of each winding package Pw in association with the information related to the judgment of each winding package Pw. However, the present invention is not limited thereto. The body control device 5 may not store information on the judgment of each winding package Pw in the body storage unit 5c. In this case, the marking operation by the marking unit is necessary.

(4) In the previous embodiment, the body control device 5 causes the winding device 19 to perform the marking operation. However, the present invention is not limited thereto. When the body control device 5 stores the individual information defining the wound package in the body storage unit 5c in association with the contamination information, the winding device 19 may not perform the marking operation.

(5) In the previous embodiment, the initial amount information is stored in the machine body control device 5 as a value common to all spindles 9 of the false twist machine 1. However, the present invention is not limited thereto. For example, the plurality of spindles 9 may be divided into a plurality of groups. The body control device 5 may be configured to set initial amount information on each of the plurality of components. Alternatively, the body control device 5 may be configured to set initial amount information for each spindle 9. In this case, the machine body control device 5 may be configured to acquire initial amount information (or information of initial values of remaining time) corresponding to each of the plurality of yarn feeding packages Ps. More specifically, each time a new yarn feeding package Ps is mounted on the yarn feeding package holding portion 20, initial amount information or the like concerning the new yarn feeding package Ps may be acquired individually.

(6) In the previous embodiments, the operator performs the replacement work of the yarn feeding package. However, the present utility model is not limited thereto. The replacement of the yarn feeding package may be performed by, for example, a creel robot, not shown. The wire processing apparatus 100 may further include a winding package conveying device, not shown, for collecting and conveying the formed winding package Pw.

(7) In the previous embodiment, the yarn Y is detected from the start of unwinding and the end of unwinding of the yarn supply package Ps by the yarn detection sensor 24 having the 1 st detection unit 25 and the 2 nd detection unit 26. However, the present utility model is not limited thereto. For example, as shown in fig. 9, the yarn feeding section 2a of the false twisting machine 1a may be provided with a detecting section 41 having a different configuration from the yarn detecting sensor 24 in each spindle 9 a. The detecting unit 41 may include, for example, a supply sensor 42 and a knotting portion sensor 43 (a yarn connecting portion detecting unit and an information acquiring unit according to the present utility model). The supply sensor 42 is configured to be able to detect whether the yarn Y is being supplied from the 1 st mounting portion 22 (unwinding start). The knotting portion sensor 43 is configured to be able to detect the knotting portion K that is arranged at a predetermined position in a stationary manner. In this configuration, when the knotting portion K moves from the predetermined position and the knotting portion K is not detected by the knotting portion sensor 43, it can be determined that the yarn feeding package switching (unwinding end) has occurred. In other words, in this modification, the knotting portion sensor 43 acquires switching information. This allows the movement of the knotting portion K to be directly detected, and thus improves the accuracy of the execution timing of the formation ending process. Based on the detection result of the supply sensor 42, it is possible to know which wire Y is being supplied from the 1 st mounting portion 22 and the 2 nd mounting portion 23 at the time of the wire feed package switching. In this way, even when the detection result of the knotted portion K is used, it is possible to reliably know which yarn Y is being fed from the 1 st attachment portion 22 and the 2 nd attachment portion 23. The knotting portion sensor 43 may be configured to detect the knotting portion K that is moving.

(8) In the previous embodiment, the body control device 5 determines whether or not the yarn feeding package switching has occurred based on the detection result of the yarn detecting sensor 24 or the knotting portion sensor 43. That is, the signal of the detection result corresponds to the switching information of the present utility model. However, the present utility model is not limited thereto. The machine control device 5 may determine whether or not the yarn feeding package switching has occurred by using the calculation result of the remaining amount of the yarn Y contained in the package during unwinding. For example, the machine body control device 5 may determine that the yarn feeding package switching has occurred when the calculated remaining amount is zero. In this case, the information of the remaining amount of the yarn Y contained in the package during unwinding corresponds to the switching information of the present utility model. The body control device 5 corresponds to an information acquisition unit of the present utility model.

(9) In the previous embodiment, the machine body control device 5 obtains the information of the unwinding speed V based on the rotational speed information of the 1 st godet 11. However, the present utility model is not limited thereto. As another example, the machine body control device 5 may store the rotation speed information of the 2 nd godet 16 and the ratio information of the rotation speed of the 1 st godet 11 to the rotation speed of the 2 nd godet 16. The machine body control device 5 may acquire information on the unwinding speed based on these information. Alternatively, the machine body control device 5 may acquire information on the weight of the yarn Y unwound from the yarn supply package Ps per unit time as unwinding unit amount information instead of the unwinding speed information. Such information may be input to the body control device 5 in advance by an operator, for example.

(10) In the above embodiment, the body control device 5 performs the process of recording the contamination information in order to reliably distinguish the predetermined winding package from the other winding packages Pw. However, the present utility model is not limited thereto. The body control device 5 may not perform the recording process of the mixed information. For example, the body control device 5 may cause the display of the body output unit 5b to display information indicating that the predetermined winding package is formed, and notify the operator of the formation of the predetermined winding package. In this case, the information may not be recorded.

(11) In the previous embodiment, the machine body control device 5 controls each part of the false twist processing machine 1. However, the present utility model is not limited thereto. For example, the management device 101 may control each part of the false twist texturing machine 1. In this case, the management apparatus 101 is included in the control unit of the present utility model.

(12) In the previous embodiment, the information management unit 110 includes a plurality of body control devices 5 and a management device 101. However, the present utility model is not limited thereto. That is, the information management unit 110 may include a computer device (not shown) other than the body control device 5 and the management device 101. Alternatively, the information management unit 110 may include only the body control device 5 or the management device 101.

(13) Each yarn feeding package holding portion 20 may be configured to hold 3 or more yarn feeding packages Ps. In this case, the ends of the yarn Y included in the 3 or more yarn packages Ps may be appropriately connected to each other.

(14) In the previous embodiment, the yarn processing apparatus 100 includes a plurality of false twist processing machines 1. However, the present utility model is not limited thereto. The yarn processing apparatus 100 may be provided with only one false twisting machine 1. Further, the management apparatus 101 may not be provided. The false twist machine 1 includes a plurality of spindles 9, but is not limited thereto. That is, the number of spindles 9 provided in the false twist machine 1 may be one. In other words, the number of yarn feeding package holding sections 20 included in the yarn feeding section 2 may be one.

(15) The present utility model may be applied to other yarn processing machines instead of the false twisting machine 1. For example, the present utility model can be applied to an air flow machine (wire processing machine) described in japanese unexamined patent publication No. 2002-088605.
