    Description
    Introduction to the invention
    1. Field of the invention The present invention relates to a device for predicting the processing of a yarn, a device for processing a yarn and a method for predicting the processing of a yarn, each suitable for predicting the processing of a yarn .
    2. Description of the prior art [0002] For example, a device for managing a pneumatic spinning machine adapted to spin a yarn by air has a simulation function of clearing to emit a simulation result in the event of cutting and elimination of a yarn defect. The clearing simulation function is a function in which, based on collected distribution data indicating the status of a yarn and a clearing setting defined by an operator, a number of eliminations of yarn defects are expected which must be cut and deleted, and where a forecast result is displayed. The clearing setting is a condition for cutting and eliminating the yarn defect included in the yarn.
    [0003] By changing the clearing setting, the operator can confirm a post-modification forecast value of the number of eliminations of yarn defects that must be cut and eliminated. With this function, the operator can find, for example, an appropriate clearing setting when starting the spinning of a yarn with a new batch setting.
    [0004] A pneumatic spinning device having such a clearing simulation function is described, for example, in the published Japanese patent application no. 2007-211 363.
    Summary of the invention [0005] In a clearing simulation function described in the published Japanese patent application no. 2007 211 363, when the clearing setting is changed, only a post-change prediction result of the number of yarn defect eliminations that need to be cleared is displayed, and it is difficult to determine if the clearing setting following the change of the setting is appropriate or not.
    [0006] An object of various aspects of the present invention consists in providing a device for predicting the processing of a yarn, a device for processing a yarn and a method for predicting the processing of a yarn which allow to determine in a simple manner whether the clearing setting after a change of setting is appropriate or less and reducing the time period in which an appropriate clearing setting is achieved.
    [0007] A first aspect of the present invention consists in a device for predicting the processing of a yarn suitable for predicting the processing of a yarn, which includes an acquisition section, an input section, a generation section and an output section . The acquisition section is suitable for acquiring the distribution data indicating the status of a yarn. The input section is used to enter the clearing settings, which are the conditions for cutting and eliminating a yarn defect included in a yarn. The generation section is able to generate, based on the distribution data and the clearing settings, forecast results relating to the processing of the yarn. The output section is suitable for outputting the forecast results generated by the generation section. The output section is able to simultaneously output a first of the forecast results generated based on a first of the clearing settings, which has been entered in the input section and is the most recent, and a second of the forecast results generated based to a second of the clearing settings before the first of the forecast results is generated.
    Consequently, an operator can simultaneously examine the first of the forecast results generated based on the first of the clearing settings, which has been entered in the input section and is the most recent, and the second of the forecast results generated in based on the second of the clearing settings previously entered. Therefore, it is possible to easily determine whether the clearing setting following the setting change is appropriate or not. Furthermore, since it is possible to simultaneously examine the predictive results before and after the setting, it is possible to reduce the time period to obtain an appropriate clearing setting.
    [0009] A second aspect of the present invention consists in a device for predicting the processing of a yarn suitable for predicting the processing of a yarn, which includes an acquisition section, an input section, a generation section and an output section. . The acquisition section is suitable for acquiring distribution data indicating the state of a yarn. The input section is adapted to enter the clearing settings, which are the conditions for cutting and eliminating a yarn defect included in a yarn. The generation section is able to generate, based on the distribution data and the clearing settings, forecast results relating to the processing of the yarn. The exit section is able to issue, next to each other, a first of the forecast results generated based on a first of the clearing settings, which has been entered in the input section and is the most recent, and a second of the forecast results generated based on a second of the clearing settings before the first of the forecast results is generated.
    Accordingly, the operator can examine, side by side, the first of the forecast results generated based on the first of the clearing settings, which has been entered in the input section and is the most recent, and the second of forecast results generated based on the second of the clearing settings previously entered. Therefore, it is possible to easily determine whether the clearing setting following the setting change is appropriate or not. Furthermore, since the predictive results before and after the setting can be confirmed in a state in which they are located next to each other, it is possible to reduce the period of time in which an appropriate clearing setting is obtained.
    The output section may output a direction indicating display, indicating that a change has been made from the second of the forecast results to the first of the forecast results, together with the first of the forecast results and the second of the forecast results . In this case, the operator can easily understand if the forecast results are prior or subsequent to the change of the setting.
    The output section may comprise a display section having a display screen on which it is possible to accept an input operation, and a display control section suitable for controlling an image displayed in the display section. The display control section can display in the display section, together with the first of the prediction results and the second of the prediction results, a Cancel button to cancel the first of the clearing settings and, when the Cancel button, the display control section can display a two-dimensional field of a yarn defect in the second of the clearing settings on the display section. In this case, the operator, by performing the Cancel button input operation while seeing the first of the forecast results and the second of the forecast results displayed, can select an appropriate forecast result. In addition, the operator can examine the two-dimensional field of the yarn defect according to the forecast result selected.
    The display control section can display on the display section, together with the first of the prediction results and the second of the prediction results, an OK key to accept a setting change at the first of the clearing settings and, when it is once the OK button has been entered, the display control section can display a two-dimensional field of a yarn defect in the first of the clearing settings on the display section. In this case, by performing the OK button input operation while viewing the first of the forecast results and the second of the forecast results displayed, the operator can select an appropriate forecast result. In addition, the operator can examine the two-dimensional field of the yarn defect according to the forecast result selected.
    The output section may comprise a display section having a display screen on which it is possible to accept an input operation, and a display control section designed to control an image displayed on the display section. The display control section can display on the display section, together with the first of the forecast results and the second of the forecast results, an OK button to accept a setting change at the first of the clearing settings and, when the OK button input operation, the display control section can display a two-dimensional field of a yarn defect in the first of the clearing settings on the display section. In this case, by performing the OK button input operation while viewing the first of the forecast results and the second of the forecast results, the operator can select an appropriate forecast result. In addition, the operator can examine the two-dimensional field of the yarn defect according to the forecast result selected.
    [0015] Before the OK button or Cancel button is entered, the display control section can display the two-dimensional field of the yarn defect on the display section in the first of the clearing settings. In this case the operator can examine the two-dimensional field of the yarn defect in the first of the clearing settings even in a phase preceding the execution of the operation of entering the OK key or the Cancel key, and can select an appropriate prediction result while confirming the second two-dimensional field.
    [0016] Before the OK button or Cancel button is entered, the display control section can display the two-dimensional field of the yarn defect in the display section in the second of the clearing settings. In this case, the operator, when performing the Cancel button input operation, can immediately examine the two-dimensional field of the yarn defect in the second of the clearing settings before changing the setting.
    The output section can output the first of the forecast results and one of the second of the forecast results. In this case, you can minimize the amount of information emitted by the exit section.
    The output section can output the first of the forecast results and two or more between the seconds of the forecast results. In this case, the operator can examine a plurality of forecast results.
    The predictive results can include a number of yarn defect eliminations that need to be cut and eliminated. In this case, the operator can easily determine whether the clearing setting after the setting change is appropriate or not, while examining the number of yarn defect eliminations.
    The number of eliminations can comprise a number of eliminations per type of yarn defect. In this case, the operator can easily determine whether the clearing setting following the setting change is appropriate or not, while examining the number of eliminations by type of yarn defect.
    The number of eliminations can comprise a number of eliminations per unit of time. In this case, the operator can easily determine whether the clearing setting following the setting change is appropriate or not, while examining the number of eliminations of yarn defects per unit of time.
    The number of eliminations can comprise a number of eliminations per unit of length of the yarn. In this case, the operator can easily determine whether the clearing setting following the setting change is appropriate or not, while examining the number of eliminations of yarn defects per unit of yarn length. [0023] The number of eliminations can include a sum of the numbers of eliminations of yarn defects in the entire sector of the yarn whose distribution data are acquired by the acquisition section. In this case, the operator can examine the sum of the yarn defect elimination numbers in the entire yarn sector.
    The predictive results may comprise a predictive result of a working index of the yarn processing. In this case, the operator can easily determine whether the clearing setting following the setting change is appropriate or not, while confirming the working index of the yarn processing.
    The yarn processing prediction device further comprises a specification section adapted to specify one or a plurality of spinning units for which the generation section generates the prediction results. The acquisition section is capable of acquiring the distribution data on a plurality of yarns which must be processed by the plurality of yarn processing units, each suitable for performing the yarn processing. The generation section can generate the forecast results based on the distribution data on a yarn that must be worked by the yarn processing unit specified by the specification section. In this case, the yarn processing prediction device can output the prediction results on the specified single or plurality of spinning units.

An acquisition section is designed to acquire distribution data on a yarn that must be processed by the yarn processing unit.
    [0027] With the yarn processing device, it is possible to easily determine whether the clearing setting following the setting change is appropriate or not. It is also possible to reduce the period of time to obtain an appropriate clearing setting.
    A fourth aspect of the present invention consists of a method for predicting the processing of a yarn performed in a yarn processing device suitable for providing for the processing of the yarn. The method of forecasting the processing of a yarn includes an acquisition phase, an input phase, a generation phase and an output phase. The acquisition phase consists in acquiring distribution data indicating the status of a yarn. The entry phase consists in accepting an entry of the clearing settings, which are the conditions for cutting and eliminating a yarn defect included in a yarn. The generation phase consists in generating, based on the distribution data and the clearing settings, forecast results relating to the processing of the yarn. The exit phase consists in issuing the forecast results generated in the generation phase. In the exit phase, a first of the forecast results generated based on a first of the clearing settings, which was accepted in the input phase and is the most recent, and a second of the forecast results generated based on a second of the clearing settings accepted before the first of the prediction results is generated.
    With the yarn processing prediction method, since it is possible to simultaneously examine the prediction results before and after the setting change, it is possible to determine in a simple way whether the clearing setting following the setting change is or not appropriate. Furthermore, since it is possible to simultaneously examine the forecast results before and after the setting change, it is possible to reduce the period of time to obtain an appropriate clearing setting.

    With the yarn processing prediction method, since it is possible to examine the predictive results before and after the setting change arranged side by side, it is possible to determine in a simple way whether the clearing setting after the change setting is appropriate or not. In addition, since it is possible to examine the predictive results before and after the setting change in a state in which they are next to each other, it is possible to reduce the time period to obtain an appropriate clearing setting.

    Detailed description of preferred embodiments [0033] An embodiment of the present invention will be illustrated below with reference to the attached drawings. In the description of the drawings, equal reference numbers indicate equal elements and redundant descriptions will be omitted. In the present description, the terms "upstream" and "downstream" indicate respectively upstream and downstream in the direction of movement of a yarn during spinning.
    [0034] A spinning machine (yarn processing device) 1 illustrated in fig. 1 comprises a plurality of spinning units (yarn processing unit) 2 arranged side by side, a yarn joining vehicle 3, a general control device (yarn processing prediction device) 50, a box of the motor 5 and a box of the compressor 80. The operation of each section of the spinning machine 1 is controlled by the general control device 50. The box of the compressor 80 houses a source of negative pressure (compressor) suitable for generating a suction flow in each section of the spinning unit 2 and the like. The motor box 5 houses a motor adapted to feed each section of the spinning unit 2 and the like. In a factory where the spinning machine 1 is installed, a passage for the operator is provided, which extends in the direction of the arrangement of the spinning units 2, on one side of a yarn path of a yarn 10 with respect to the vehicle of yarn splicing 3. An operator performs an operation, monitoring or similar for each of the spinning units 2 from the passage to the operator.
    [0035] As illustrated in figs. 1 and 2, each spinning unit 2 comprises a traction device 7, a pneumatic spinning device 9, a yarn accumulator device 12, a paraffin device 14 and a winding device 13, in this order from upstream to downstream.
    [0036] The traction device 7 is arranged near an upper end of a housing 6 of the spinning machine 1 in the direction of the machine height of the spinning machine 1. A bundle of fibers 8 (see fig. 2 ) fed by the traction device 7 is spun by the pneumatic spinning device 9. After the yarn 10 fed by the pneumatic spinning device 9 has passed through a yarn monitoring device 52, the yarn 10 is fed further downstream by the accumulator device of the yarn 12, and the yarn 10 is subjected to waxing by the waxing device 14. Subsequently, the yarn 10 is wound by the winding device 13 and in this way a cone 45 is formed. [0037] The traction device 7 is adapted to produce the bundle of fibers 8 by pulling a ribbon 15. As illustrated in fig. 2, the traction device 7 comprises four pairs of rollers, which are a pair of rear rollers 16, a pair of third rollers 17, a pair of intermediate rollers 19 equipped with a conveyor belt 18 and a pair of front rollers 20. The lower rollers of each pair of rollers 16, 17, 19 and 20 are mechanically driven by the motor housing 5 or by a drive source (not shown) supplied individually. Each pair of rollers 16, 17, 19 and 20 is respectively driven at rotation speeds which are different from each other. Consequently, the upstream fed web 15 is pulled into the fiber bundle 8 by each pair of rollers 16, 17, 19 and 20, and the fiber bundle 8 is fed to the pneumatic spinning device positioned downstream.
    The pneumatic spinning device 9 is adapted to add twists to the fiber bundle 8 by using a swirling air flow in order to produce the yarn 10. Although the drawings and a detailed description are omitted, the pneumatic spinning device 9 it includes a fiber guide section, a swirl flow nozzle and a hollow guide shaft element. The fiber guiding section is adapted to guide the bundle of fibers 8 fed by the traction device 7 to a spinning chamber formed inside the pneumatic spinning device 9. The vortex flow generation nozzle is arranged around a path of the bundle of fibers 8 and is adapted to generate the swirling flow in the spinning chamber.
    [0039] By means of the swirling flow, one fiber end of the bundle of fibers 8 inside the spinning chamber is inverted and performs a swirling motion. The hollow guide shaft element is adapted to guide the yarn 10 produced 10 from the spinning chamber towards the outside of the pneumatic spinning device 9.
    The yarn accumulator device 12 is arranged downstream of the pneumatic spinning device 9. The yarn accumulator device 12 has a stretching function, an anti-loosening function and a tension regulation function. The drawing function is the function designed to stretch the yarn 10 coming from the pneumatic spinning device 9 by applying a predetermined tension to the yarn 10. The anti-loosening function is a function designed to prevent a loosening of the yarn 10 by the accumulation of the yarn 10 fed by the pneumatic spinning device 9, for example during a yarn joining operation by the yarn joining vehicle 3 The tension adjustment function is a function designed to regulate the tension so that a variation of tension on one side of the winding device 13 does not propagate on one side of the pneumatic spinning device 9. As shown in fig. 2, the yarn storage device 12 comprises a yarn storage roller 21, a yarn hooking element 22, an upstream guide 23, an electric motor 25, a downstream guide 26 and a storage quantity sensor 27.
    [0041] The hooking element of the yarn 22 is adapted to hook the yarn 10 to winding the yarn 10 around an external perimetric surface of the yarn accumulator roller 21 rotating in a manner integral with the yarn accumulator roller 21 in a state in which hook the yarn 10.
    The yarn accumulator roller 21 is adapted to accumulate the yarn 10 by winding a predetermined quantity of the yarn around its external perimeter surface. The yarn accumulator roller 21 is rotatably driven by the electric motor 25. The yarn 10 wound around the outer perimeter surface of the yarn accumulator roller 21 is wound tightly around the yarn accumulator roller 21 by the rotation of the yarn accumulator roller 21 , which pulls a yarn 10 arranged upstream of the yarn accumulator device 12. This means that, by rotating the yarn accumulator roller 21 with the yarn 10 wound around its outer peripheral surface at a predetermined rotation speed, the yarn accumulator device Yarn 12 transports yarn 10 downstream at a predetermined speed while applying the predetermined tension to yarn 10 and stretching yarn 10 from the pneumatic spinning device 9 at a predetermined speed.
    [0043] The accumulation quantity sensor 27 is adapted to detect, without contact, an accumulation quantity of the yarn 10 wound around the yarn accumulation roller 21. The accumulation quantity sensor 27 sends to the general control device 50 a quantity signal of accumulation indicating a detected amount of accumulation of the yarn 10.
    The upstream guide 23 is arranged slightly upstream of the yarn accumulator roller 21. The upstream guide 23 is adapted to guide the yarn 10 appropriately towards the external perimeter surface of the accumulator roller 21. The upstream guide 23 prevents the twists of the yarn 10 which propagate from the pneumatic spinning device from propagating downstream of the upstream guide 23.
    [0045] The yarn monitoring device 52 is positioned on a front side of the housing 6 of the spinning machine 1 (side of the passage for the operator) and between the pneumatic spinning device 9 and the yarn accumulator device 12.
    The yarn 10 produced by the pneumatic spinning device 9 passes through the yarn monitoring device 52 before being wound by the yarn accumulator device 12. The yarn monitoring device 52 is adapted to detect the state of a yarn 10. The state of the yarn includes the thickness of a yarn. The state of the yarn can also determine the presence or absence of a foreign substance. In other words, the yarn monitoring device 52 can detect a foreign substance included in the yarn 10.
    [0047] A cutter 57 able to cut the yarn 10 following the detection of a yarn defect is arranged upstream of the yarn monitoring device 52. The cutter 57 can be omitted, and the yarn 10 can be cut by interrupting the air supply to the pneumatic spinning device 9.
    The paraffin device 14 is located downstream of the yarn accumulator device 12. The paraffin device 14 is adapted to apply paraffin to the yarn 10 which flows from the yarn accumulator device 12 towards the winder device 13.
    [0049] The winding device 13 comprises a support section of the package 71, a winding cylinder 72 and a translatory device 75. The support section of the package 71 is a portion in which the package 45 is rotatably supported and includes a portion fixed 71 a fixed in the housing 6 and an oscillating portion 71 b capable of oscillating back and forth with respect to the fixed portion 71 a. The oscillating portion 71 b is supported in an oscillating manner around a shaft 70 in the fixed portion 71 a. The oscillating portion 71 b is equipped with a bobbin holder (not shown) adapted to rotatably support a bobbin 48 around which the yarn 10 is wound.
    [0050] The winding cylinder 72 is adapted to create a contact with an external perimeter surface of the reel 48 or an external perimeter surface of the reel 45 and to rotatably actuate the reel 45. The translation device 75 comprises a translation guide 76 in able to engage the yarn 10. By operating the winding cylinder 72 by means of an electric motor (not shown), while simultaneously actuating the translation guide 76 with an alternative movement by means of an actuation means (not shown), the winding device 13 rotates the package 45 which is in contact with the winding cylinder 72, while translating the yarn 10 and, consequently, winding the yarn 10 around the bobbin 45. The translation guide 76 of the translating device 75 is operated in common in each spinning unit 2 by a common shaft for the plurality of spinning units 2.
    [0051] Next, the splicing vehicle of yarn 3 will be described. As illustrated in figs. 1 and 2, the yarn joining vehicle 3 is adapted to move by means of wheels 42 on a track 41 along the direction of the arrangement of the spinning units 2 in a lower portion of the housing 6 in which the traction device 7 is arranged, the pneumatic spinning device 9 and the like. The splicing vehicle of the yarn 3 comprises a splicer 43, a suction tube 44 and a suction mouth 46.
    After a breakage or a cut of the yarn has occurred in a given spinning unit 2, the splicing vehicle of the yarn 3 moves towards said spinning unit 2 along the track 41 and stops. The suction tube 44 sucks and captures one end of the yarn fed by the pneumatic spinning device 9 and guides the end of the captured yarn towards the splicer 43 while simultaneously oscillating vertically with an axis as its center. The suction mouth 46 sucks and captures one end of the yarn coming from the bobbin 45 supported by the winding device 13 and guides the end of the captured yarn towards the splicer 43 while swinging vertically with an axis as its center. The splicer 43 performs a splicing operation of the yarn to join the guided ends of the yarn together.
    [0053] Next, a control system of the spinning machine 1 will be described. As illustrated in fig. 3, the general control device 50 is adapted to send an instruction to a controller of unit 29, to a controller of the splicing vehicle of yarn 49, to a controller of the compressor 89 and the like to control each section of the spinning machine 1 The general control device 50 is arranged, for example, in the motor box 5. The general control device 50 is connected to the unit controller 29, to the yarn joining vehicle controller 49 and to the compressor controller 89 by means of a communication line L1. Data communication is carried out via the communication line L1 between the general control device 50 and the unit controller 29, the splicing vehicle controller 49 of the yarn and the controller of the compressor 89.
    [0054] The plurality of spinning units 2 is divided into groups each formed by a predetermined number (for example four spindles, eight spindles or similar). The unit controller 29 is provided for each group formed by the predetermined number of spinning units 2. The unit controller 29 is adapted to control each of the predetermined number of spinning units 2 which are under its control according to the instruction coming from the general control device 50. The unit controller 29 is arranged, for example, in the vicinity of the spinning units 2 which are under its control. The unit controller 29 is connected to the yarn monitoring device 52 provided for each of the predetermined number of spinning units 2 which are under its control by means of a communication line L2. Data communication is carried out via the communication line L2 between the unit controller 29 and the yarn monitoring device 52. It is also possible to provide a unit controller 29 for each spinning unit 2 without dividing the spinning units into groups 2.
    The yarn splicing vehicle controller 49 is adapted to control the movement and splicing of the yarn of the splicing vehicle 3 based on an instruction from the general control device 50. The splicing vehicle controller of the yarn 49 is arranged, for example, in the splicing vehicle of the yarn 3. The controller of the compressor 89 is able to control the source of negative pressure and similarity present in the box of the compressor 80 on the basis of an instruction coming from the control device general 50. The controller of the compressor 89 is arranged, for example, in the box of the compressor 80.
    The yarn monitoring device 52 provided for each spinning unit 2 comprises a detection section 52a and a yarn monitoring control section 52b. The detection section 52a is adapted to detect a temporal variation in the thickness of the yarn 10 spun by the pneumatic spinning device 9. The detection section
    52a is suitable for sending waveform data indicating the temporal variation of the thickness of the yarn 10 detected at the monitoring control section of the yarn 52b. An optical monitoring device and a capacitive monitoring device can be used as detection section 52a. The optical monitoring device irradiates the yarn 10 with light and detects the temporal variation of the thickness of the yarn through a variation of the quantity of light received. The capacitive monitoring device causes the yarn 10 to cross an electric field and detects the temporal variation of the thickness of the yarn (mass) through a variation of the capacitance.
    The monitoring control section of the yarn 52b is suitable for evaluating the input waveform data and for calculating the state of a yarn 10, i.e. the distribution data indicating a length and thickness of a defect of yarn included in yarn 10. When the detection section 52a detects a yarn defect that must be cut and eliminated and the yarn defect is cut and eliminated by the cutter 57, the yarn monitoring control section 52b sends the distribution to the general control device 50 via the unit controller 29. Furthermore, when a predetermined amount of data is accumulated, the monitoring control section of the yarn 52b, via the unit controller 29, sends to the general control device 50 I distribution data relating to a remaining yarn defect that must not be cut or eliminated.
    In this way, the general control device 50 acquires the distribution data indicating the length and thickness of the yarn defect included in the yarn 10 as the state of the yarn coming from the monitoring monitoring section of the yarn 52b of the monitoring device of the yarn 52 provided for each spinning unit 2. As described above, the yarn defect acquired by the general control device 50 comprises not only the yarn defect that must be cut and removed, but also the remaining yarn defect.
    [0059] Next, the general control device 50 will be described in detail. The general control device 50 controls the plurality of spinning units 2 so that the yarn 10 is produced by the pneumatic spinning device 9 and is wound by the device. winder 13. The general control device 50 has a clearing simulation function in which a simulation result is emitted in case of cutting and elimination of the yarn defect. The clearing simulation function performed in the general control device 50 and the like will be described below.
    The clearing simulation function is a function capable of predicting, based on the distribution data indicating the state of the yarn and a clearing setting defined by the operator, a number of eliminations of the yarn defects that must be cut and deleted, and to view the expected number of deletions. The clearing setting is a condition for cutting and eliminating the yarn defect included in a yarn. By entering the clearing setting, the operator can confirm a prediction value of the number of eliminations of yarn defects in this clearing setting. In addition, by changing the clearing setting, the operator can confirm a prediction value of the number of yarn defect eliminations in the clearing setting following the change. The visualization of a prediction result and the like by the clearing simulation function is carried out by using a display section (an output section, a yarn processing prediction device) 100 arranged in the motor box 5.
    [0061] As illustrated in fig. 4, the general control device 50 functionally comprises an acquisition section 501, a storage section 502, an operation acceptance section 503, a generation section of a two-dimensional field 504, a prediction section (a generation section ) 505 and an image generation section (a display control section, an output section) 506. The acquisition section 501 is adapted to acquire the distribution data issued by the yarn monitoring control section 52b provided in each spinning unit 2. The storage section 502 is adapted to store the distribution data acquired by the acquisition section 501 for each spinning unit 2.
    The operation acceptance section 503 is adapted to accept various types of input operations performed through the display section 100. The display section 100 is equipped with a display screen 110 on which the input operations are accepted. by pressing a button or touching the screen. The operator can perform various types of input operations by pressing, for example, a key displayed on the display screen 110. The operation acceptance section 503 accepts an input operation of the clearing setting, an input operation of a Cancel key, an input operation of an OK button, an input operation to specify a spinning unit 2 and the like.
    [0063] By way of example, an image illustrated in fig. 5 is displayed on the display screen 110. Specifically, as illustrated in fig. 5, a sector specification key (a specification section) A, a clearing input key (an input section) B, a two-dimensional field C, and a clear key E are displayed on the display screen 110. The image shown in fig. 5 is an image prior to performing an entry operation to change the clearing setting.
    The sector specification button A is a button for specifying one or a plurality of spinning units 2 for which a prediction section 505 generates a prediction result. By carrying out an input operation of the sector specification key A displayed on the display screen 110, the operator can specify one or a plurality of spinning units 2 for which the two-dimensional field, the prediction result and the like of the plurality of spinning units (spindles) 2 provided in the spinning machine 1. In other words, the sector specification key A is a key for specifying a sector of the spinning units 2 provided for the clearing simulation.
    The input key of the clearing setting B is a key for entering the clearing setting, which is a condition for cutting and eliminating the yarn defect included in yarn 10. The operator can enter the setting of clearing by performing an input operation of the clearing setting input key B displayed on the display screen 110.
    [0066] The clearing setting can be performed by type of yarn defect. In the present embodiment it is possible to carry out a setting for a button (NEP), an enlargement (S), a short thick yarn (L), a long thick yarn (LL), a short fine yarn (T) and a fine yarn long (TT) as types of yarn defect. As for a button, for example, as a reference it is possible to set a ratio with respect to the thickness. Regarding the enlargement, the short coarse yarn, the long coarse yarn, the short fine yarn and the long fine yarn, it is possible to set a ratio with respect to the thickness as a reference and a length of the yarn defect. The input button of the clearing setting B includes a button (not shown) to specify a sector of a class cut in case of a class cut. Class cutting refers to the execution of cutting and elimination of a yarn defect corresponding to a predetermined region in the event that a two-dimensional field C, which will be described below, is divided into a plurality of regions (classes) based on thickness and length. The type of defects of a yarn is not limited to the types listed above by way of example.
    [0067] The two-dimensional field C is generated by the generation section of the two-dimensional field 504. The two-dimensional field C is formed with the length of the yarn defect as a horizontal axis and the thickness of the yarn defect as a vertical axis, and displays the defect of spun like a point on one of its coordinates. The generation section of the two-dimensional field 504 determines a position of a point on the two-dimensional field C on the basis of a length and thickness indicated by the distribution data. In the two-dimensional field C shown in fig. 5, a black square point and an empty round point respectively indicate a yarn defect that must be cut and eliminated and a remaining yarn defect that must not be cut or eliminated. In the two-dimensional field C, in addition, a clearing limit C10 is displayed set by the input key of the clearing setting B. The clearing limit C10 is a border that indicates whether the yarn defect is cut and eliminated. The yarn defects positioned on one side of a reference thickness (horizontal axis indicating that the yarn thickness is 100%) of the yarn 10 with respect to the clearing limit C10 are the yarn defects that must not be cut or eliminated (round stitch empty), and the yarn defects positioned on the opposite side of the reference thickness (horizontal axis indicating that the yarn thickness is 100%) of the yarn 10 with respect to the clearing limit C10 are the yarn defects that must be cut and eliminated (stitch black square).
    [0068] In the present embodiment, the clearing limit C10 is constituted, for example, by a boundary line C11 which represents a cutting and elimination border of the button, a boundary line C12 which represents a cutting and elimination border of the button. enlargement, a C13 boundary line representing a cutting and elimination boundary of the short thick yarn, a C14 boundary line representing a cutting and elimination boundary of the long thick yarn, a C15 boundary line representing a cutting boundary and elimination of the short fine yarn and a boundary line C16 which represents a cutting and elimination border of the long fine yarn. The clearing limit C10 varies its shape and position according to a set condition entered via the input key of the clearing setting B. [0069] In the two-dimensional field C shown in fig. 5, a yarn defect corresponding to a region C20 specified as a class cut region must be cut and eliminated. The yarn defect corresponding to the C20 region is indicated by the black square point. By viewing this two-dimensional field C on the display screen 110, the operator can confirm a distribution status or similar of the yarn defect that must be cut and eliminated.
    [0070] The Clear E key is a key for deleting the distribution and similar data stored in the storage section 502. By performing an operation to enter the Clear E key, for example in the event that a batch setting is changed during the spinning of a yarn, the operator can delete the distribution data stored in the storage section 502.1 distribution data and similar stored in the storage section 502 can be automatically deleted when the batch setting changes.
    [0071] Referring again to fig. 4, the generation section of the two-dimensional field 504 is adapted to generate the two-dimensional field C (see fig. 5). More specifically, the generation section of the two-dimensional field 504 acquires the distribution data of the last 100 km from each of the last distribution data of the spinning units 2 specified using a sector specification key A, among the yarn distribution data 10 stored in the storage section 502. The acquired distribution data are not limited to the data of the last 100 km. The distribution data can be less than 100 km, for example they can be immediately following the start of the spinning of the yarn 10. The generation section of the two-dimensional field 504 also acquires the clearing setting accepted by the acceptance section of the operation 503 Subsequently, the generation section of the two-dimensional field 504 generates the two-dimensional field C indicating a state of distribution of a yarn defect in the case in which the determination of the yarn defect is based on the acquired clearing setting.
    The prediction section 505 is adapted to generate a predictive result D. The predictive result D is a table which includes in number of eliminations of the yarn defects that must be cut and eliminated and similar, and which is displayed on the display screen 110. In fig. 6 shows an example of the predictive result D. As illustrated in fig. 6, the prediction result D indicates, by type of yarn defect, the number of eliminations of the yarn defects that must be cut and eliminated. The number of eliminations of yarn defects is indicated as a number of eliminations per unit of length of the yarn (/ 100 km), a number of eliminations per unit of time (/ h) and a sum of the numbers of eliminations. In the present embodiment, the number of eliminations per unit of length of the yarn is the number corresponding to the case of a prediction of the number of eliminations of the yarn defects that must be cut and eliminated based on the distribution data of the last 100 km of the yarn 10 of the latest (current) distribution data. The number of eliminations per unit of time is the number that corresponds to the case of a forecast of the number of eliminations based on the distribution data for the hour following the time of the last (current) distribution data.
    [0073] The sum of the elimination numbers is a sum of the yarn defects that must be cut and eliminated in the whole sector of the yarn 10 in which distribution data are acquired by the acquisition section 501. The greater the length of the yarn 10 which must be produced by spinning, the greater the sum of the elimination numbers. The sum of the elimination numbers can be reset, for example in the event that an operation is performed to enter the Delete key E.
    The result of prediction D comprises a number of eliminations of the yarn defects that must be cut and eliminated in the event that a class cut is performed. The predictive result D further comprises a predictive result of a working index of the yarn processing. The operating index is the index of an operating time in the case in which the cutting and the elimination are performed according to the clearing setting defined when an operating time in the case in which the cutting and the The elimination of the yarn defect is set to 100%. The operating time is the period of time in which the yarn 10 is actually produced and wound. By displaying this predictive result D on the display screen 110, the operator can confirm a difference in the number of eliminations of each yarn defect thanks to a difference in the clearing setting. The operator can also confirm a difference in the operating index thanks to the difference in the clearing setting.
    In order to generate the prediction result D, first the prediction section 505 acquires from the storage section 502 the distribution data used when the generation section of the two-dimensional field 504 generates the two-dimensional field C. Furthermore the section forecast 505 acquires the clearing setting accepted by the acceptance section of operation 503.
    The prediction section 505 calculates, per unit of yarn length, per unit of time and for each sum of the eliminated numbers, the number of eliminations of the yarn defects that must be eliminated by type of yarn defect in the case in which to which the yarn defect is determined on the basis of the clearing setting acquired and the number of eliminations of the yarn defects that must be eliminated in case of class cutting. The prediction section 505 also calculates the forecast result of the working index of the yarn processing. The prediction section 505 generates the prediction result D illustrated in fig. 6 using the calculated elimination numbers, the operating index and the like. The timing with which the prediction result D is displayed on the display screen 110 will be described later.
    [0077] An image generation section 506 is adapted to display the two-dimensional field C generated by the generation section of the two-dimensional field 504 on the display screen 110. In the event that the operator performs the operation of changing the setting of clearing, the image generation section 506 also causes the prediction result D generated by the prediction section 505 to appear on the display screen 110 based on the changed clearing setting.
    [0078] The process of each section and an example of an image displayed on the display screen 110 will be illustrated below if the operator performs an operation to modify the clearing setting.
    [0079] When the operation of modifying the clearing setting is accepted by the acceptance section of operation 503, the generation section of the two-dimensional field 504 generates the two-dimensional field C after changing the setting. More specifically, the generation section of the two-dimensional field 504 generates the two-dimensional field C after changing the setting based on the distribution data used for the generation of the two-dimensional field C prior to changing the setting and the next clearing setting changing the setting.
    Furthermore, when the operation of modifying the clearing setting is accepted by the acceptance section of operation 503, the prediction section 505 generates a prediction result (a second prediction result) DX preceding the modification of the setting and a forecast result (a first forecast result) D after the setting change. More precisely, the prediction section 505 generates the DX prediction result before changing the setting based on the distribution data used for the generation of the two-dimensional field C displayed on the display screen 110 before the modification operation of the the clearing setting and the clearing setting prior to changing the setting. As for timing, the generation of the DX prediction result before changing the setting is not limited to taking place after performing the clearing setting modification operation but can take place before the modification operation is performed . Furthermore, the prediction section 505 generates the prediction result D following the modification of the setting based on the distribution data used for the generation of the two-dimensional field C displayed on the display screen 110 before the modification operation of the clearing setting and clearing setting after changing the setting.
    [0081] When the operation to modify the clearing setting is accepted by the acceptance section of operation 503, as illustrated in fig. 7, the image generation section 506 displays on the display screen 110 the two-dimensional field C following the modification of the setting generated by the generation section of the two-dimensional field 504. Fig. 7 illustrates a modification of the clearing setting in a case where a setting value (300%) of the thickness of an NEP illustrated in fig. 5 is changed to 350% (see the input button for the clearing setting B). Consequently, the position of the boundary line C11 is changed, which is the boundary of cutting and deleting the button before changing the setting.
    The image generation section 506 causes the prediction result D prior to the modification of the setting generated by the prediction section 505 to appear next to each other (in figure 7 the reference number for the prediction result preceding the modification of the setting is suitably indicated with «DX») and the prediction result D following the modification of the setting generated by the prediction section 505, in a part of a region (a region at the top right in the example of the fig. 7) of the two-dimensional field C following the modification of the setting.
    The image generation section 506 simultaneously displays, next to each other, the DX prediction result prior to changing the setting and the predicting result D after changing the setting, so that the operator can confirm both simultaneously. For example, even if the timing of the display of the prediction result DX prior to the setting change and the timing of the display of the prediction result D following the change of the setting are different, the two forecast results DX and D they are displayed simultaneously with a certain timing. In fig. 6 DX and D prediction results are displayed side by side in the horizontal direction, but the direction of the arrangement is not limited to this.
    Furthermore, the image generation section 506 displays on the display screen 110, between the prediction result DX prior to the modification of the setting and the prediction result D following the modification of the setting, an arrow F (display indicating direction) which indicates the forecast result following the setting change. In addition to the arrow F, it is possible to use another symbol, or similar, suitable to indicate a direction of the modification.
    [0085] When the clearing setting is changed by the operator, as shown in fig. 7, the two-dimensional field C following the modification of the setting, the DX forecast result previous to the modification of the setting and the prediction result D following the modification of the setting are displayed on the display screen 110. Consequently, the operator can easily determine whether or not to change the clearing setting by confirming the two-dimensional field C following the change of the setting, the prediction result DX preceding the modification of the setting and the prediction result D following the modification. of the setting that are displayed on the display screen 110. In addition, when the forecast result D following the setting change and the like is displayed, the arrow F is also displayed. Consequently, when changing the clearing setting, the The operator can easily recognize which of the two prediction results DX and D displayed on the display screen 110 is the prediction result D following the change of the setting.
    The image generation section 506 displays an OK button G and an Cancel button H near the prediction results DX and D on the display screen 110. The OK button G is a button suitable for accepting the clearing setting after changing the setting. The Cancel button H is a button to cancel the clearing setting after changing the setting.
    [0087] The operator performs an operation for entering the OK key G or the Cancel key H examining the predictive results DX and D preceding and following the modification of the setting and the like which are displayed by means of a pop-up window on the display screen 110. When the OK key G input operation is accepted by the operation acceptance section 503, the image generation section 506 continues to display on the display screen 110 the two-dimensional field C following the modification of the setting and eliminates the pop-up window of the DX and D forecast results. As a result, the operator can easily examine the two-dimensional field C following the change of the setting. In a spinning operation following modification of the setting, the general control device 50 controls each section of the spinning unit 2 so that the defect of the yarn 10 is cut and eliminated on the basis of the clearing setting following the modification setting.
    On the other hand, when the Cancel H key input operation is accepted by the operation acceptance section 503, the image generation section 506 still displays the two-dimensional field C prior to changing the setting on the screen display 110 and eliminates the pop-up window of the prediction results DX and D (i.e. that the display screen returns to the state illustrated in fig. 5). When the Cancel H key input operation is performed, the general control device 50 maintains the current clearing setting.
    The general control device 50 is physically constituted by a computer comprising, for example, a CPU (central processing unit), a ROM (read-only memory) and a RAM (random access memory).
    [0090] A process flow (a method of predicting the processing of a yarn) relating to the execution of the clearing simulation function by the general control device 50 will be described below. The following process will be described below. operation to enter the change of the clearing setting performed by the operator. As illustrated in fig. 8, the acceptance section of the operation 503 accepts the operation of entering the modification of the clearing setting performed by the operator by means of the input key of the clearing setting B displayed on the display screen 110 (step S101: step of entry).
    The generation section of the two-dimensional field 504 acquires the distribution data and the clearing setting following the modification accepted by the acceptance section of the operation 503 and generates the two-dimensional field C following the modification of the setting based on the data distribution and clearing setting after modification (step S102). Prediction section 505 generates the DX prediction result prior to changing the setting based on distribution data and clearing setting prior to changing the setting. Furthermore, the prediction section 505 acquires the distribution data and the clearing setting following the change accepted by the acceptance section of the operation 503 and generates the prediction result D following the modification of the setting based on the distribution data and the clearing setting following the change of the setting (phase S103: acquisition phase, generation phase). As illustrated in fig. 7, the image generation section 506 displays on the display screen 110 the two-dimensional field C following the modification of the setting, the prediction result DX preceding the modification of the setting, the prediction result D following the modification of the setting and similar (phase S104).
    Next, the image generation section 506 determines whether an OK key input operation G (step S105) has been performed. In case the OK G key input operation has been performed (step S105: Yes), the image generation section 506 will keep the display of the two-dimensional field C following the modification of the setting and eliminate the pop-up window. up of the DX and D forecast results.
    On the other hand, in the event that the OK G key input operation has not been performed (step S105: No), the image generation section 506 will determine if an input operation has been performed. Cancel button H (phase S106). In the event that the Cancel H key input operation has not been performed (step S106: No), the image generation section 506 will return to the process of step S105. If the Cancel H key input operation has been performed (step S106: Yes), the image generation section 506 will eliminate the pop-up window of the prediction results DX and D and display the previous two-dimensional field C changing the setting on the display screen 110 (phase S107: exit phase).
    [0094] This embodiment is configured as described above and, when the operation of changing the clearing setting is performed in order to perform the clearing simulation function, as shown in fig. 7, the DX prediction result prior to setting change and D prediction result after setting change are displayed side by side on the display screen 110 simultaneously. As a result, the operator can simultaneously examine the result DX prediction prior to setting change and D prediction result following setting change arranged side by side. As a result, it is possible to easily determine whether a clearing setting after changing the setting is appropriate or not. In addition, since the predictive DX and D results before and after the setting change can be examined simultaneously while they are displayed next to each other, it is possible to reduce the period of time necessary to obtain an appropriate clearing setting.
    [0095] When the predictive DX result prior to the change of the setting and the predictive result D following the change of the setting are displayed, the arrow F is displayed on the display screen 110. Consequently, the operator can easily recognize if the DX and D prediction results are before or after the setting change.
    [0096] When the DX prediction result preceding the change of the setting and the prediction result D following the modification of the setting are displayed, the Cancel button H is displayed on the display screen 110, capable of canceling the next prediction result D changing the setting. In this case, the operator can select an appropriate forecast result by performing an input of the Cancel button H while viewing the DX forecast result previous to the change of the setting and the prediction result D following the change of the setting. When the Cancel H key input operation is performed, the two-dimensional field C prior to changing the setting is displayed on the display screen 110. As a result, the operator can examine the two-dimensional field C of the yarn defect according to the selected forecast result.
    [0097] If the DX prediction result prior to the change of the setting and the prediction result D following the change of the setting are displayed, the OK button G is displayed on the display screen 110, capable of accepting the result of prediction D after changing the setting. In this case, the operator can select an appropriate prediction result by performing an OK key G operation while viewing the DX prediction result prior to setting change and D prediction result following setting change. . When the OK G key is entered, the two-dimensional field C following the setting change is displayed on the display screen 110. As a result, the operator can examine the two-dimensional field C of the yarn defect according to the selected forecast result.
    [0098] Before the Cancel H key input operation is performed, the image generation section 506 displays the two-dimensional field C following the modification of the setting on the display screen 110. In this case, the operator can examine the two-dimensional field C after changing the clearing setting even before performing the OK G key or Cancel H key input operation, and can select an appropriate prediction result while examining the two-dimensional field C.
    [0099] The image generation section 506 displays on the display screen 110 the forecast result D following the change of the setting and a DX forecast result previous to the change of the setting. In this case, the amount of information displayed on the display screen 110 is minimal and, therefore, the operator can easily determine whether or not the clearing setting following the change of the setting is appropriate.
    [0100] The prediction result D includes the number of eliminations of the yarn defects that must be cut and eliminated. As a result, the operator can easily determine whether or not the clearing setting following the setting change is appropriate while examining the number of yarn defect eliminations.
    The result of prediction D includes the number of eliminations of yarn defects by type, the number of eliminations per unit of time, the number of eliminations per unit of length of the yarn, the number of eliminations of yarn defects in all the sectors of the yarn 10 and the operating index. Consequently, the operator can easily determine whether or not the clearing setting following the change of the setting is appropriate while examining these numerical values.
    [0102] The prediction section 505 generates the prediction result D based on the distribution data relating to one or a plurality of spinning units 2 specified by the sector specification key A. In this case, the operator can examine the result of prediction D and the like of a desired spinning unit 2 among the plurality of spinning units 2 present. [0103] Although an embodiment of the present invention has been described, the present invention is not limited to the above described embodiment. For example, after the operation to change the clearing setting has been accepted through the acceptance section of operation 503, as shown in fig. 9, the image generation section 506 can maintain the display of the two-dimensional field C prior to changing the setting until the OK G key input operation is performed. In this case, the operator can select a prediction result appropriate while examining the two-dimensional field C of the yarn defect in the clearing setting prior to changing the setting.
    [0104] The image generation section 506 may also display a plurality of prediction results on the display screen 110 prior to changing the clearing setting. For example, as illustrated in fig. 10, the image generation section 506 can display on the display screen 110 the prediction result D, a prediction result D1 and a prediction result D2, generated respectively on the basis of the clearing settings accepted by the operation acceptance section 503 with different timings. Fig. 10 only illustrates the prediction results D, D1 and D2 of the images displayed on the display screen 110. The clearing setting on which the prediction result D is based is the most recent clearing setting accepted by the acceptance section of the operation 503. The clearing setting on which the prediction result D2 is based is the oldest clearing setting accepted by the acceptance section of operation 503. In this case, the operator can determine whether or not it is appropriate. clearing setting following modification of setting while examining the plurality of prediction results.
    [0105] As illustrated in fig. 7, the image generation section 506 causes the prediction results DX and D to appear in a part of the region (the upper right region in the example of Fig. 7) of the two-dimensional field C superimposedly, but on the display 110, only the DX and D prediction results can be displayed without the two-dimensional field C.
    [0106] The image generation section 506 displays the prediction results DX and D preceding and following the modification of the clearing setting next to each other on the display screen 110 ma, as shown in fig. 11, it is possible that a prediction result From is displayed on the display screen 110 in which the numbers of eliminations and similar preceding and following the execution of the setting change are shown in a table. Fig. 11 illustrates only the prediction result Da displayed on the display screen 110.
    [0107] The image generation section 506 of the general control device 50 outputs this information by displaying on the display screen 110 the two-dimensional field C, the prediction result D and the like, but the destination towards which the general control device 50 emits the two-dimensional field C, the prediction result D and the like is not limited to this. For example, the general control device 50 can emit the two-dimensional field C, the prediction result D and the like by printing them on paper or the like. Furthermore, in addition to printing, for example the general control device 50 can emit the two-dimensional field C, the prediction result D and the like by transmitting them to an external device or writing them in a portable and similar storage medium.
    [0108] The clearing simulation function is performed by the general control device 50 which controls the operation of each section of the spinning machine 1, but the present invention is not limited to the performance of the general control device 50 installed on the spinning machine 1. For example, as shown in fig. 12, a yarn processing prediction device 60 adapted to perform the clearing simulation function and the display section 100 can be positioned at a certain distance from the spinning machine 1. The yarn processing prediction device 60 comprises the acquisition section 501, the storage section 502, the acceptance section of the operation 503, the generation section of the two-dimensional field 504, the forecast section 505 and the image generation section 506, which are described with reference to fig. 4. The display section 100 comprises the display screen 110 described above. Said yarn processing device 60 and this display section 100 can be arranged, for example, in a management device 200 suitable for managing a plurality of spinning machines 1.
    [0109] In the present embodiment, the acquisition section 501 can acquire the waveform data issued by the detection section 52a in addition to acquiring the distribution data from the monitoring control section of the yarn 52b. Alternatively, it is possible that only the waveform data from the detection section 52a to the general control device 50 is output without the distribution data from the monitoring monitoring section of the yarn 52b to the general control device 50 In this case, in the general control device 50, a calculation section can be provided for calculating the distribution data starting from the waveform data, and the calculated distribution data can be acquired from the acquisition section 501.
    [0110] The clearing simulation function is performed on the yarn 10 produced by the spinning unit 2, but the clearing simulation function can also be performed in a yarn processing device other than the spinning machine 1. For example , the clearing simulation function described above can be performed by a yarn processing device equipped with a sensor (in the present embodiment, the yarn monitoring device 52) adapted to detect a variation in the thickness of a yarn such as a automatic winder suitable for winding the yarn, an open-end spinning machine, a ring spinning machine or similar.
