INTRODUCTION TO THE INVENTION 1. Field of the Invention The present invention relates to a device for setting a clearing limit and a machine for winding a yarn. 2. Description of the prior art [0002] Some of the control devices used in yarn winding machines have, for example, a function for displaying a yarn clearing limit, i.e. a threshold for judging whether to remove a yarn defect (e.g. , see Japanese Patent No. 5 680 653), on a two-dimensional field on which a matrix of length and thickness of the yarn defects is drawn.
SUMMARY OF THE INVENTION
[0003] In such configurations, even if an operator attempts to modify the shape of a part of a clearance limit in such a way that a yarn defect removal count reaches a predetermined target removal count, there are cases where the yarn defect removal count to be removed based on the modified yarn clearing limit does not reach the predetermined target removal count, and adapting the shape of the clearing limit becomes difficult. [0004] It is an object of the present invention to provide a device for setting the yarn clearing limit and a yarn winding machine capable of displaying a clearing limit with which a count to remove the yarn defects to be removed in a part of the limit clearing set is set to a goal removal count.
[0005] A device for setting the clearing limit according to an aspect of the present invention comprises a display unit which displays on a two-dimensional field, on which a matrix of the length and thickness of the yarn defects is traced, a clearing limit which it is a threshold for judging whether to remove a yarn defect and consists of a plurality of sections; a first input section that receives the selection of at least one section; a removal count acquisition section which acquires an objective removal count of the yarn defects to be removed in the selected section; a section for processing the clearing limit that generates the clearing limit; a control section of the display that displays the clearing limit generated on the display unit; and a memory unit which stores in it the yarn defect data consisting of a plurality of yarn defect data indicating the length and thickness of the yarn defect. When the section is selected using the first input section and the removal count acquisition section acquires the target removal count, the clearing limit processing section generates a temporary clearing limit based on the yarn defect data and to the goal removal count so that a yarn defect removal count of the selected section reaches the goal removal count. The display control section displays on the display unit the temporary clearing limit based on the goal removal count generated in the clearing limit processing section.
[0006] In the device for setting the clearing limit above, a part of the clearing limit can be selected. Furthermore, the clearing limit setting device generates the temporary clearing limit so that the yarn defect removal count to be removed in the selected section reaches the entered target removal count, and displays the temporary clearing limit generated on the display unit. In this way, according to the device for setting the clearing limit referred to above, it is possible to display the clearing limit with which the count to remove the yarn defects to be removed in a part of the clearing limit reaches the objective removal count. With this configuration, by selecting an objective section and entering the target removal count, an operator can confirm the clearing limit where the yarn defect removal count to be removed in the target section reaches the target removal count.
[0007] In the device for setting the clearing limit above, the display unit can be a touch panel.
[0008] In the device for setting the clearing limit described above, the first input section can be a current clearing limit displayed on the display unit and can receive the selection of the section that is touched between the plurality of sections. With this configuration, the operator can easily select a desired section of the clearing limit.
[0009] In the device for setting the clearing limit above, the display control section displays a plurality of first push-buttons on the display unit, which respectively correspond to the plurality of the sections. The first input section can be the plurality of the first buttons displayed on the display unit and can receive the selection of the section corresponding to the first button touched between the plurality of the first buttons. With this configuration, the operator can easily select any carefully displayed section of the clearing limit as the desired section.
[0010] In the device for setting the clearing limit above, when the temporary clearing limit is displayed on the display unit based on the target removal count, the display control section can display the selected section using the first entry section in a distinguishable way. With this configuration, the operator can easily identify the selected section among the plurality of sections that constitutes the clearing limit.
[0011] In the device for setting the clearing limit described above, together with the selection of the section using the first input section and the acquisition of the target removal count by the removal count acquisition section, the processing section the clearing limit can generate the temporary clearing limit based on the target removal count, and together with the generation of the temporary clearing limit based on the target removal count, the view control section can display on the display unit the temporary clearing limit based on the goal removal count. In other words, when the goal removal count is entered, the clearing limit setting device automatically generates and displays the temporary clearing limit set according to the target removal count. With this configuration, the operator can instantly confirm the temporary clearing limit set according to the entered goal removal count.
[0012] The device for setting the clearing limit referred to above may further comprise a second input section which receives the selection of at least one section between the plurality of the sections of the current clearing limit displayed on the display unit; a third input section showing a plurality of displacement directions in which the clearing limit moves on the two-dimensional field and receives the selection of the displacement direction; and a removal count calculation section that calculates the yarn defect removal count to be removed based on the clearing limit. When the section is selected using the second input section and the displacement direction is selected using the third input section, the clearing limit processing section can generate the temporary clearing limit in which the selected section is moved in the direction of selected displacement of a predetermined amount. Once the temporary clearing limit is generated by moving the section, the removal count calculation section can calculate the yarn defect removal count to be removed in the selected section based on the temporary clearing limit generated by moving the section and yarn defect data. The display control section can display on the display unit the yarn defect removal count calculated from the removal count calculation section and the temporary clearance limit generated by moving the section. Consequently, a section of the clearing limit can be selected and the selected section can be moved. In the present configuration, the third input section which moves the selected section indicates the plurality of displacement directions for the clearance limit. Therefore, the operator can intuitively move the selected section using the third input section in the desired direction of movement. Furthermore, the device for setting the clearing limit calculates on the basis of the temporary clearing limit the count to remove the yarn defects to be removed in the selected section using the second input section, and displays the removal count calculated on the display unit . With this configuration, the operator can grasp the yarn defect removal count that changes when the section that constitutes the clearing limit is moved, and the clearing limit (the temporary clearing limit) after the move.
[0013] In the device for setting the clearing limit referred to above, the second input section can be the current clearing limit displayed on the display unit and can receive the selection of the section touched by the operator between the plurality of sections. With this configuration, the operator can easily select a desired section of the clearing limit.
[0014] In the device for setting the clearing limit of the above, the display control section can display on the display unit a plurality of second push-buttons which respectively correspond to the plurality of the sections. The second input section can be a plurality of the second buttons displayed on the display unit and can receive the selection of the section corresponding to the second button touched between the plurality of the second buttons. With this configuration, the operator can easily select any minutely displayed section 52a of the clearance limit 52 as the desired section.
[0015] In the device for setting the clearing limit referred to above, while displaying on the display unit the temporary clearing limit generated based on the section displacement, the display control section can display the selected section using the second section of entry in a distinguishable way. With this configuration, the operator can easily identify the selected section among the plurality of sections that constitutes the clearing limit.
[0016] In the device for setting the clearing limit above, the third input section can be a drive unit which is displayed by the display control section on the display unit. With this configuration, it is not necessary to provide a separate drive unit, and the drive unit can be supplied to the operator at an appropriate time by displaying it on the display unit.
[0017] In the device for setting the clearing limit referred to above, together with the selection of the section using the second input section and the selection of the displacement direction using the third input section, the clearing limit processing section can generate the temporary clearing limit by moving the selected section; in conjunction with generating the temporary clearing limit by moving the section, the removal count calculation section can calculate the yarn defect removal count; and in conjunction with the generation of the temporary clearing limit by moving the section and the calculation of the yarn defect removal count, the display control section can display on the display unit the temporary clearing limit generated based on the section displacement and to the yarn defect removal count. In other words, when the direction of movement of the section constituting the clearing limit is entered, the device for setting the clearing limit automatically displays the count to remove the yarn defects to be removed in the section for which the direction of displacement and the temporary clearing limit in which the selected section is moved. With this configuration, the operator can instantly confirm the yarn defect removal count set according to the displacement of the section that constitutes the clearing limit and the temporary clearing limit in which the selected section is moved.
[0018] In the device for setting the clearing limit described above, the display control section can display on the display unit the temporary clearing limit together with the current clearing limit. With this configuration, the operator can compare the current clearing limit with the temporary clearing limit. [0019] In the device for setting the clearing limit described above, the clearing limit processing section can set the current clearing limit or the temporary clearing limit as a new clearing limit. With this configuration, the operator can set the current clearing limit or the temporary clearing limit as a new clearing limit.
Each of the sections can be set according to the types of yarn defects. With this configuration, a section of the yarn clearing limit can be easily selected according to the type of yarn defects. Furthermore, the yarn defect can be removed for a desired removal count according to the type of the selected yarn defect.
When an objective removal count is entered which is applicable through a plurality of sections comprising the selected section, the removal count acquisition section can acquire an objective removal count assigned to the selected section using a predetermined method for assigning as goal removal count to remove in the selected section. With this configuration, the target removal count corresponding to the selected section can be acquired even if the target removal count of the selected is not directly entered.

[0025] Exemplary embodiments of the present invention are explained in detail below with reference to the attached drawings. The identical or corresponding structural components are indicated by the same reference numbers in the drawings and any redundant explanation of the same is omitted.
[0026] As shown in fig. 1, a yarn winding machine 1 comprises a plurality of yarn winding units 2, a plurality of unit control devices 3, and a main control device (clearing limit setting device) 4. The machine of winding of the yarn 1 is, for example, an automatic winding machine, an air jet stretcher machine, a rotor spinning machine (open-end spinning machine), a ring spinning machine (ring spinning machine), and the like.

[0028] The feeding section of the yarn 21 feeds the yarn. In a configuration in which the yarn winding machine 1 is an automatic winder, the feeding section of the yarn 21 comprises a support device for the bobbin which supports the yarn feeding bobbin and the like. In a configuration in which the yarn winding machine 1 is an air-jet spinning machine, the supply section of the yarn 21 comprises an ironing device which stretches a bundle of fibers, a jet-spinning device. air that twists the stretched fiber bundle by the action of a whirling air stream and forms the yarn, and the like.
[0029] The yarn monitoring section 22 monitors the yarn positioned between the yarn supply section 21 and the winding section 24 and detects the yarn defects. The yarn monitoring section 22 comprises a sensing device 22a and a control device 22b. The detection device 22a is an optical sensor which detects a temporary variation in the thickness of the yarn based on the modification of a quantity of light received when the light is emitted on the yarn, an electrostatic capacity sensor which detects a temporary variation in the thickness of the yarn. based on the modification of an electrostatic capacity when the yarn is passed through an electric field, and the like. The detection device 22a sends to the control device 22b data of waveforms which indicate the temporary variation in the thickness of the yarn. The control device 22b calculates, based on the data of the wave forms, the data of the yarn defects, which comprise the data of a plurality of yarn defects which indicate the length and thickness of the yarn defects, and sends the yarn defect data to the unit control device 3. When the unit control device 3 judges on the basis of the yarn defect data that the yarn defect must be removed, for example, the yarn is cut by a cutter provided in the yarn winding unit 2. In a configuration in which the yarn winding machine 1 is an air-jet spinning machine, the yarn is automatically cut when the air-jet spinning device interrupts the formation of the yarn. Furthermore, the yarn monitoring section 22 can also detect a foreign substance contained in the yarn, yarn breakage, and the like.
[0030] After the yarn is cut to remove the yarn defect detected by the yarn monitoring section 22, or when the yarn monitoring section 22 detects a yarn breakage, the yarn joining section 23 joins the yarn coming from it. from the feeding section of the yarn 21 and the yarn coming from the winding section 24.

The yarn splicing device is a device - such as a splicing device that uses compressed air, a punch for seed yarn, a knotter that joins the yarns mechanically, and the like - which joins the guided yarns. Alternatively, in a configuration in which the yarn winding machine 1 is, for example, a spinning machine, the junction section of the yarn 23 can be a yarn splicing carriage which can move through a plurality of the winding units of the yarn. yarn 2.
[0031] The winding section 24 forms the bobbin by winding the yarn around the bobbin. The winding section 24 comprises a support arm, a winding cylinder, a brace device, and the like. The support arm rotatably supports the bobbin. The winding cylinder comes into contact with the surface of the bobbin supported by the supporting arm and rotates the bobbin. The base device arranges the yarn with a predetermined width on the rotating cone. Furthermore, in a configuration in which a motor directly rotates the bobbin, the winding cylinder can have a bed slot.
[0032] As shown in fig. 3, the main control device 4 comprises a touch panel (display unit) 41, a processing unit 42, and a storage unit 43. The touch panel 41 displays various information to the operator, receives various information entered by the operator. operator, and the like. The processing unit 42 acquires from each control device of the units 3 the data of the yarn defects sent by the monitoring section of the yarn 22 of the yarn winding unit 2. The processing unit 42 stores in the storage unit 43 for each of the yarn winding units 2 the yarn defect data acquired by associating them with the information indicating whether the yarn defect is removed or left as such. The processing unit 42 and the storage unit 43 are physically constituted by a CPU (Centrai Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.
[0033] Functionally, the processing unit 42 comprises a removal count acquisition section 42a, a clearing limit processing section 42b, a removal count calculation section 42c, and a display control section 42d .
[0034] The control section of the display 42d generates and displays on the touch panel 41 a two-dimensional field, together with a clearing limit generated by the clearing limit processing section 42b. Fig. 4 is a diagram showing an example of a screen of the touch panel 41. As shown in fig. 4, a two-dimensional field 51 is a coordinate system showing a matrix of length and thickness of the yarn defects. In other words, the two-dimensional field 51 has coordinate axes of length and thickness of the yarn defect. In the figure, the length of the yarn defect is the horizontal axis and the thickness of the yarn defect (in proportion to the thickness of the reference yarn) is the vertical axis. A clearing limit 52 is a threshold (boundary line) which indicates whether to remove the yarn defect, and consists of a plurality of sections 52a. The clearing limit 52 is set for various channels that indicate the types of the yarn defects, such as node N1 and N2, tangle S1 and S2, long L, and T1 and thin T2. That is, sections 52a correspond to the respective types of yarn defects (node N1 and N2, tangle S1 and S2, long L, T1 and thin T2, and the like). In other words, the clearance limit 52 is a threshold which is divided (classified) previously into the sections 52a which correspond to the respective types of the yarn defects. Accordingly, a section of the yarn clearing limit 52 according to the type of yarn defect can be easily selected and modified.
[0035] Furthermore, the processing unit 42 causes each of the control devices of the units 3 to control the operation of the corresponding yarn winding unit 2 in such a way that a yarn defect with a value within an area on a side of the thickness of the reference yarn (one side of the horizontal axis where the thickness of the yarn defect is 0%) with respect to the clearance limit 52 is not removed, and a yarn defect with a value within an area on the opposite side of the side of the thickness of the reference yarn (the side of the horizontal axis where the thickness of the yarn defect is 0%) with respect to the clearance limit 52 is removed.
[0036] The display control section 42d determines a position of the yarn defect on the two-dimensional field 51 based on the yarn defect data stored in the storage unit 43, and displays the yarn defect as a stitch on the touch panel 41 In the present configuration, the control section of the display 42d shows on the two-dimensional field 51 the defect of the yarn still remaining on the yarn with a white round point and the defect of the yarn removed from the yarn with a black square point. Furthermore, at any given time, only a predetermined number of points indicating the yarn defects of the immediate past are displayed on the touch panel 41.
[0037] The control section of the display 42d shows on the touch panel 41 a column of the current setting values 53 and a column of the simulation setting values 54. In the column of the current setting values 53, the setting information of is displayed. a current clearing limit 52 (the clearing limit currently set 52). Specifically, in the column of the current setting values 53, the current values of the length and thickness of the yarn defect which determine the current clearing limit 52 are displayed for each channel. In the column of the simulation setting values 54, the setting information of a temporary clearing limit is displayed 52. Specifically, in the column of the simulation setting values 54, the simulation values of the length and thickness of the yarn defect which determine the temporary clearing limit 52 are displayed for each channel. Each of the sections 52a which constitute the current clearance limit 52 is set so as to combine the corresponding current values of the length and thickness of the yarn defect. For example, when at least one section 52a of the current clearing limit 52 (as explained in detail below) is modified, the simulation values of the length and thickness of the yarn defect corresponding to the modified section 52a are also modified.
[0038] «ALL» (ALL) displayed on the left side along the column of the current setting values 53 and the column of the simulation setting values 54 indicates that all channels are included. In the column of the current setting values 53 and in the column of the simulation setting values 54, the sections corresponding to the various channels (ALL, N1, N2, S1, S2, L, T1, T2) displayed on the left side included «ALL» (ALL) are arranged as buttons (second buttons) 55. Consequently, the control section of the display 42d shows on the touch panel 41 the buttons 55 which correspond to the plurality of the sections 52a of the clearing limit 52.
[0039] The control section of the display 42d displays on the touch panel 41 a column of the current results 56 and a column of the simulation results 57. In the column of the current results 56, a count for removal of the yarn defects (n) and the value of the same calculated per unit of length (100 kilometers (km) in the figure) (/ 100 km) is displayed for each channel as a result of processing the yarn of the current clearing limit 52. The yarn defect removal count (n ) displayed in the column of the current results 56 is a measured count of the yarn defects which have been removed and is equivalent to the number of points plotted for a yarn defect with a value within the area on the opposite side to the yarn thickness side of reference (the side of the horizontal axis where the thickness of the yarn defect is 0%) with respect to the current clearing limit 52. Alternatively, the count of removal of yarn defects calculated based on a yarn defect removal count (n) per time unit (e.g., an hour) can be displayed in the current results column 56.
[0040] The result of the processing of the yarn carried out based on the temporary clearing limit 52 is displayed in the column of the simulation results 57. In the column of the simulation results 57, the count to remove the yarn defects (n) and the value of the same calculated per unit of length (100 km in the figure) (/ 100 km) is displayed for each channel as a result of the processing of the yarn carried out based on the temporary clearing limit 52. The yarn defect removal count ( n) displayed in the column of simulation results 57 is an estimated count based on the measured count of the yarn defects that have been removed, and is equivalent to the number of points plotted for a yarn defect with a value within the area on the side opposite to the side of the thickness of the reference yarn (the side of the horizontal axis where the thickness of the yarn defect is 0%) with respect to the clearing limit current 52. Alternatively, the yarn defect removal count calculated based on the yarn defect removal count (n) per time unit (e.g., one hour) can be displayed in the simulation results column 57 .
[0041] In the column of the current results 56 and in the column of the simulation results 57, a node "N" displayed on the left side corresponds to the node N1 and N2; a tangle «S» corresponds to the tangle S1 and S2; a long "L" corresponds to long L, and a thin "T" corresponds to thin Ti and T2. "Sum" (Sum) corresponds to the total channels of node N1 and N2, tangle 51 and S2, long L, and T1 and thin T2. «YF» corresponds to the total channels of node N1 and N2, tangle S1 and S2, long L, T1 and thin T2, and to other channels (for example, a channel F indicating contaminant (colored contaminant), a channel C indicating that the count of the yarn (thickness of the yarn) is different, and similar). In the column of current results 56 and in the column of simulation results 57, the sections indicating various channels including «YF» and «Sum» (Sum) are set up as buttons (first buttons) 58. Consequently, the control section of the display 42d shows on the touch panel 41 the buttons 58 which correspond to the plurality of the sections 52a of the clearing limit 52.
[0042] The section for processing the clearing limit 42b generates the clearing limit 52. Specifically, for example, when the clearing limit 52 is not generated at the beginning of the winding of the yarn and the like, the processing section of the yarn clearing limit 42b generates clearing limit 52 based on a series of predefined values previously set by the operator. For example, when the yarn defect data is not stored in the storage unit 43 at the beginning of the yarn winding, the clearing limit processing section 42b generates the yarn clearing limit 52 based on the set of default values by the operator based on past experience and the like. Alternatively, after the yarn has been wound, if a predetermined amount of yarn defect data is stored, the clearing limit processing section 42b can automatically generate the yarn clearing limit 52 based on the two-dimensional field distribution 51 in the stored yarn defect data.
[0043] Furthermore, the clearing limit processing section 42b generates the clearing limit 52 based on the clearing simulation instructions provided by the operator. In the present configuration, the clearing simulation includes two simulations. A first clearing simulation is a simulation with which a yarn clearing limit 52 to achieve an objective removal count of the yarn defects is estimated based on the target removal count. A second simulation of clearing is a simulation with which at least one of the sections 52a constituting the clearance limit 52 is displaced and the count to remove the defects of the yarn to be removed is estimated based on the temporary clearing limit 52 in which the section 52a is moved. The details of the first clearing simulation and the second clearing simulation will be explained below.
[0044] When performing the first clearing simulation, the removal section of the removal count 42a acquires the target removal count to be used when removing the yarn defect. The operator can enter the target removal count using an input button on the main control device 4, an input button displayed on the touch panel 41, and the like. The acquisition section of the removal count 42a acquires the target removal count which is entered by the input key provided on the main control device 4 and the like. However, the target removal count can be entered into the main control device 4 using an input section other than the input key using a predetermined input section).
[0045] When the second clearing simulation is performed, the calculation section of the removal count 42c calculates (estimates) the yarn defect removal count to be removed based on the clearing limit 52.
[0046] The first clearing simulation and the second clearing simulation will be explained below as an example.
[0047] First simulation of clearing
First of all, the first clearing simulation will be explained with which the clearance limit 52 necessary to achieve an objective removal count of the yarn defects is estimated (generated) based on the objective removal count. In the present explanation, it is assumed that the current clearing limit 52 is already set. The current clearing limit 52 is a clearing limit 52 set for the effective removal of the yarn defects. The processing unit 42 causes each of the control devices of the units 3 to control the operation of the corresponding winding unit of the yarn 2 so as to remove the yarn defect based on the current clearing limit 52. The first simulation of clearing is performed when, for example, the operator wants to confirm the clearing limit 52 after the defect count of the yarn to be removed has been changed.
[0048] The operator selects a section 52a (channel) so that the yarn defect removal count must be changed. Specifically, for example, as shown in fig. 5, the operator touches (presses, physically touches, and the like) a button 58 which corresponds to the tangle S between the buttons 58 to select a section 52a. When this selection is made, the operator can select a button 58 which corresponds to a channel other than the tangle S between the buttons 58, or can collectively select a plurality of the buttons 58.
[0049] In this way, the plurality of the buttons 58 (the plurality of the buttons 58 displayed on the touch panel 41 separately from the clearing limit 52) which respectively corresponds to the plurality of the sections 52a which constitutes the clearing limit 52 acts as first input section receiving the selection of the section 52a corresponding to at least one button 58 which is touched. The control section of the display 42d can display the section 52a selected on the touch panel 41 using the button 58 in a distinguishable manner, or can display the button 58 corresponding to the selected section 52a in a distinguishable manner on the touch panel 41.
[0050] The operator selects the section 52a (channel) by touching (by physically touching and similarly) the section 52a which corresponds to the tangle S (tangle S1 and S2) between the current clearing limit 52 displayed on the touch panel 41. However, when making such a selection, the operator can select a section 52a which corresponds to a channel other than the tangle S between the current clearing limit 52, can select any one of the plurality of the sections 52a, or can collectively select a plurality of the sections 52a.
[0051] In this way, the clearing limit 52 displayed on the touch panel 41 acts as the first input section receiving the selection of at least one section 52a which is touched. Alternatively, the control section of the display 42d can display the section 52a selected on the touch panel 41 using the clearance limit 52 in a distinguishable manner, or can display the button 58 corresponding to the selected section 52a in the distinguishable manner on the touch panel 41. .
[0052] The operator enters the objective removal count of the yarn defects to be removed in the selected section 52a using the input key provided on the main control device 4 and the like. The removal count acquisition section 42a acquires the target removal count entered. In the example shown in fig. 5, "0.7" is entered as the goal removal count, that is, as a count and objective removal of the yarn defects per unit length (/ 100 km) in tangle S. Consequently, in the column of the simulation results 57, the section Display control 42d displays «0.7» as the numerical value of the yarn defect removal count per unit length (/ 100 km) in tangle S. The simulation values corresponding to «YF» and «Sum» (Sum) in column of the results of simulation 57 and the count of removal of the defects (n) displayed for the tangle S yes jointly modify to the count of removal of the defects of the yarn per unit of length (/ 100 km) in the tangle S. The other numerical values in the column of simulation results 57 remain the same as those in the column of current results 56.
[0053] After the selection of the section 52a is received for which the removal count is to be modified, and the target removal count is acquired from the takeover count acquisition section 42a, the clearing limit processing section 42b generates the temporary clearing limit 52 based on the yarn defect data stored in the storage unit 43 and the target removal count acquired so that the yarn defect removal count to be removed in the selected section 52a reaches the removal count target. In the present configuration, the temporary clearing limit 52 is a clearance limit 52 which is temporarily generated to be confirmed by the operator and the like. Therefore, an actual processing of the yarn is not performed using the temporary clearing limit 52 at this stage.
[0054] When the clearing simulation is carried out using the yarn defect data stored in the storage unit 43, it is desirable for accuracy purposes to use the yarn defect data based on the result of the yarn processing (length of yarn). winding) for the 100 km or more of the yarn immediately preceding it. However, the clearing simulation is not limited to the use of the yarn defect data based on the results of yarn processing for the 100 km or more of the yarn immediately preceding it, and can be performed using the yarn defect data at the base to the result of the processing of the yarn for less than 100 km of the yarn. For example, even if "100 km" is set as the reference yarn length, the set value can be increased to "200 km" or decreased to "80 km". In such a configuration, for example, the control section of the display 42d can display a warning 59 to indicate that the clearing simulation is performed using the yarn defect data based on the result of the yarn processing for less than 100 km of the yarn.
[0055] For example, when the operator selects the button 58 corresponding to "YF" and enters the objective removal count, the processing section of the clearing limit 42b assigns an objective removal count to each of the node channels N, tangle S, L long, and thin T included under «YF», and generates the temporary clearing limit 52 so that the yarn defect removal count to be removed in the section 52a corresponding to each of the channels reaches the removal count goal attributed to the respective channel. When the target removal count is assigned to each channel, the clearing limit processing section 42b can use various attribution methods such as the weighting based on the measured values of the defect count of the past yarn. Moreover, when the operator selects the button 58 corresponding to «YF», in addition to the node N, tangle S, L long and T thin, the control section of the display 42d can assign the target removal count to other channels (for example, to channel C and the like). Similarly, when the operator selects the button 58 corresponding to "Sum" and enters the target removal number, the clearing limit processing section 42b assigns the target removal count to each node of node N, tangle S , L long and thin T included in «Sum», and generate the temporary clearing limit 52. When button 58 is selected which corresponds to «YF» or «Sum», and the removal count is attributed objective from the clearing limit processing section 42b, the display control section 42d displays in the simulation results column 57 the target removal count attributed to each channel. When the operator sets the target removal count through a plurality of sections 52a, including the selected section 52a (e.g., when the target removal count is entered for the entire clearance limit 52), the count acquisition section Removal 42a acquires the target removal count attributed using a predetermined method and assigned to the selected section 52a as the target removal count of the yarn defects to be removed in the selected section 52a.
[0056] When the temporary clearing limit 52 is generated on the basis of the target removal count from the clearance limit processing section 42b, the control section of the display 42d shows on the touch panel 41 the temporary clearing limit 52 based on the goal removal count, together with the current clearing limit 52. When the temporary clearing limit 52 is displayed on the touch panel 41 based on the target removal count, the display control section 42d displays the section 52a selected by the operator in a distinguishable way. In the example shown in fig. 5, the current clearing limit 52 is indicated by a solid line, and the temporary clearing limit 52 based on the target removal count is indicated by the solid line and a discontinuous line. The shape of the section 52a corresponding to the tangle S (SI and S2) selected by the operator on the temporary clearing limit 52 based on the target removal count is different from that of the current clearing limit 52 (a portion indicated by the discontinuous line).
[0057] Furthermore, in the column of the simulation setting values 54, the control section of the display 42d shows on the touch panel 41 the simulation values that determine the temporary clearing limit 52 based on the target removal count. When the simulation values are displayed in the column of the simulation setting values 54, the control section of the display 42d can display the simulation value of this section 52a so that the simulation value of the channel corresponding to the section 52a selected by the operator is distinguishable. In other words, the simulation value of the channel corresponding to the section 52a selected by the operator is a simulation value of a position in which the value is different from the currently set corresponding value, displayed in the column of the current setting values 53. In the example shown in fig. 5, the simulation values related to the thickness of tangles S1 and S2 are modified based on the result of the first clearing simulation.
[0058] In conjunction with the selection of the section 52a by the operator for which the yarn defect removal count must be modified and to the acquisition of the target removal count by the removal count acquisition section 42a, the section Processing of clearing limit 42b generates the temporary clearing limit 52 based on the target removal count. In other words, the selection of the section 52a by the operator whereby the counting of removal of the yarn defects must be modified and the acquisition of the goal removal count by the removal count acquisition section 42a activate the section processing of the yarn clearing limit 42b for the automatic generation of the temporary clearing limit 52 based on the target removal count without waiting for other instructions from the operator for generating the temporary clearing limit 52.
[0059] Furthermore, together with the generation of the temporary clearing limit based on the objective removal count by the clearing limit processing section 42b, the control section of the display 42d shows on the touch panel 41 the temporary clearing limit 52 based on the target removal count and the simulation values that determine the temporary clearing limit 52. In other words, the generation of the temporary clearing limit based on the target removal count by the clearing limit section 42b activates the control section of the display 42d for the automatic display of the temporary clearing limit 52 based on the target removal count and the simulation values that determine the temporary clearing limit 52 without waiting for other instructions from the operator for displaying the limit clearing yourself mporaneo 52.
[0060] The clearing limit processing section 42b sets the current clearing limit 52 or the temporary clearing limit 52 displayed on the touch panel 41 as a new clearing limit. The clearing limit 52 is set when the operator confirms the first result of the clearing simulation and then touches a button for selecting between the current clearing limit 52 and the temporary clearing limit 52.
[0061] For example, the control section of the display 42d displays an Okay button 71 and a Cancel button 72 on the touch panel 41. When the operator touches the Okay button 71, the clearing limit processing section 42b sets the temporary clearing limit 52 as the new clearing limit 52. After the temporary clearing limit 52 has been set as new clearing limit 52, the temporary clearing limit 52 is assumed as the new current clearing limit 52. Consequently, the Okay 71 button is used to reflect the temporary clearing limit 52 in the actual removal operation of the yarn defects, during the first clearing simulation.
[0062] On the other hand, when the operator touches the Cancel button 72, the clearing limit processing section 42b discards the temporary clearing limit 52 and sets the current clearing limit 52 as a new clearing limit 52. In other words, when the Cancel button 72 is touched, the clearing limit processing section 42b maintains the current clearing limit 52 as a clearing limit 52. Accordingly, the Cancel button 72 is used to discard the simulated temporary clearing limit 52 and maintain the current clearing limit 52, during the first clearing simulation.
[0063] Second clearing simulation
The second clearing simulation will be explained in which at least one of the sections 52a constituting the yarn clearing limit 52 is displaced and the count to remove the yarn defects to be removed based on the temporary clearing limit 52 in which the section 52a is moved. In the present explanation, it is assumed that the current clearing limit 52 is already set. The operator performs the second clearing simulation, for example, when there is a need to confirm the yarn defect removal count to be removed when section 52a of the current yarn clearing limit 52 is shifted (modified).
[0064] The operator selects a section 52a (channel) to be moved between the plurality of the sections 52a which constitutes the current clearing limit 52 displayed on the touch panel 41. Specifically, for example, as shown in fig. 6, the operator selects a section 52a by touching (by physically touching and similarly) a button 55 corresponding to the tangle S1 between the buttons 55. When performing this selection, the operator can select a button 55 corresponding to a channel other than tangle S1 between the buttons 55, or can collectively select a plurality of the buttons 55. For example, the operator can select all the channels by touching the button 55 which corresponds to «ALL».
[0065] Consequently, the plurality of the buttons 55 which respectively corresponds to the plurality of the sections 52a which constitutes the current clearing limit 52 (the plurality of the buttons 55 displayed on the touch panel 41 separately from the clearing limit 52) acts as a second input section which receives the selection of the section 52a which corresponds to at least one button 55 which is touched. Furthermore, the control section of the display 42d can display the section 52a selected on the touch panel 41 using the button 55 in a distinguishable manner, or it can display on the touch panel 41 the button 55 corresponding to the selected section 52a in a distinguishable manner.
[0066] The operator selects a section 52a (channel) by touching (by touching, physically touching and the like) the section 52a which corresponds to the tangle S1 of the current clearing limit 52 displayed on the touch panel 41. In making the selection, the the operator can select from the current clearing limit 52 a section 52a corresponding to a channel other than the tangle S1, or can collectively select a plurality of the sections 52a.
[0067] Consequently, the clearing limit 52 displayed on the touch panel 41 acts as a second input section which receives the selection of at least one section 52a which is touched. However, the control section of the display 42d can display on the touch panel 41 the selected section 52a using the clearing limit 52 in a distinguishable manner, or can display on the touch panel 41 the button 55 corresponding to the selected section 52a in a distinguishable manner.
[0068] When the operator selects the section 52a to be moved, the display control section 42d displays a drive unit 60 on the touch panel 41. The drive unit 60 shows a plurality of displacement directions to move the limit yarn clearing 52 on the two-dimensional field 51, and acts as a third input section that receives the selection of the direction of movement. Specifically, the drive unit 60 includes a shift direction instruction button 61, a shift entity change button 62, and a display clearing button 63. The move direction instruction button 61 shows the plurality of displacement directions for each of the predetermined angles, and receives the selection of the displacement direction. In the present explanation, the buttons which constitute the instruction button of the displacement direction 61 are set at an interval of 45 degrees around the modifying button of the displacement entity 62, and the buttons respectively indicate the directions of displacement upward, upward right, right, bottom right, bottom, bottom left, left, and top left clockwise.
[0069] When selecting a section 52a to be moved using the clearing limit 52 or the button 55 and selecting the direction of travel using the drive unit 60, the clearing limit processing section 42b generates the clearing limit temporary 52 in which the selected section 52a is displaced by a predetermined amount in the selected moving direction. The control section of the display 42d shows on the touch panel 41 the temporary clearing limit 52 generated by the clearing limit processing section 42b according to the displacement of the section 52a.
[0070] For example, as shown in fig. 6, when the operator touches the instruction button of the displacement direction 61 which indicates the direction of movement downwards, the temporary clearing limit 52 is displayed in which the selected section 52a corresponding to the tangle S1 is moved downwards by one predetermined entity. When the temporary clearing limit 52 is generated by the clearing limit processing section 42b based on the displacement of the section 52a, the control section of the display 42d shows on the touch panel 41 the temporary clearing limit 52 generated based on the movement of the section 52a, together with the current clearing limit 52. When the temporary clearing limit 52 generated based on the displacement of the section 52a is displayed on the touch panel 41, the control section of the display 42d displays the section 52a selected by the operator in a distinguishable way. In the example shown in fig. 6, the current clearing limit 52 is indicated by a continuous line, and the temporary clearing limit 52 generated based on the displacement of the section 52a is indicated by the solid line and a discontinuous line. The shape of the section 52a corresponding to the tangle S1 selected by the operator on the temporary clearance limit 52 based on the displacement of the section 52a is different from that of the current clearing limit 52 (a portion indicated by the discontinuous line).
[0071] In the column of the simulation setting values 54, the control section of the display 42d shows on the touch panel 41 the simulation values that determine the temporary clearing limit 52 generated based on the displacement of the section 52a. When the simulation values are displayed in the column of the simulation setting values 54, the control section of the display 42d can display the simulation value of the selected section 52a so that the simulation value of the channel corresponding to the section 52a selected by the operator is distinguishable.
In other words, the simulation value of the channel corresponding to the section 52a selected by the operator is a simulation value of a position in which the value is different from the currently set corresponding value, displayed in the column of the current setting values 53. In the example shown in fig. 6, the simulation value associated with the thickness of tangle S1 corresponding to section 52a selected by the operator is modified according to the direction of movement selected by the operator.
[0072] Furthermore, the change button of the displacement entity 62 in the drive unit 60 receives the modification of the entity (the predetermined amount) of which the selected section 52a must be moved when the instruction button of the direction of shift 61 is touched once. The processing section of the yarn clearing limit 42b changes the amount of movement each time the change button of the movement entity 62 is touched. That is, the displacement entity changes to a value equivalent to the value obtained by multiplying by 1 (displacement entity equal to a reference value) when the change button of the displacement entity 62 is touched once, multiplying by 10 ( amount of displacement equal to 10 times the reference value) when it is touched twice, multiplying by 100 (amount of displacement equal to 100 times the reference value) when it is touched three times, and so on. The reference value for the displacement entity can be set for each channel.
[0073] The display cancel button 63 receives instructions for canceling the display of the drive unit 60 from the touch panel 41. In other words, when one of the clearing limit 52 and the button 55 receives the selection of at least one section 52a, the display control section 42d displays the drive unit 60 on the touch panel 41, and when the display cancel button 63 is touched, the display control section 42d cancels the display of the drive unit 60 and removes the selection from section 52a.
[0074] A configuration in which the selected section 52a is moved using the drive unit 60 has been explained in the above embodiment, but is not limited to a similar configuration using the drive unit 60. For example, after the operator has selected the section 52a to be moved and entered the simulation value in the column of the simulation setting values 54, the processing section of the clearing limit 42b can generate the temporary clearing limit 52 so that it coincides with the simulation value entered. In other words, the clearing limit processing section 42b can move the selected section 52a based on the simulation value entered. The operator can enter a simulation value that determines the temporary clearing limit 52 using the input key provided in the main control device 4, the input key displayed on the touch panel 41, and the like.
[0075] When the temporary clearing limit 52 is generated by moving the section 52a, the calculation section of the removal count 42c calculates the yarn defect removal count to be removed in the selected section 52a based on the temporary clearing limit 52 generated by the displacement of the section 52a and the data of the yarn defects recorded in the column of the current setting values 53. When calculating the yarn defect removal count to be removed in the selected section 52a, the control section of the display 42d shows on the panel tactile 41 the count of defect removal of the calculated yarn. In the example shown in fig. 6, the removal count calculated by the calculation section of the removal count 42c is displayed in the simulation results column 57 as the simulation value of tangle S which includes the tangle S1 selected by the operator as a section to be moved. Moreover, the simulation values corresponding to «YF» and «Sum» (Sum) in the column of simulation results 57 are modified together with the simulation value set for tangle S. The other numerical values in the column of simulation results 57 they remain the same as those in the current results column 56.
[0076] In conjunction with the selection of the section 52a that the operator must move and the selection of the direction of movement using the drive unit 60, the clearing limit processing section 42b generates the temporary clearing limit 52 by moving the selected section 52a. In other words, the selection of the section 52a which the operator must move and the selection of the direction of movement using the drive unit 60 activate the clearing limit processing section 42b for the automatic generation of the temporary clearing limit 52 in based on the movement of section 52a without waiting for other instructions from the operator to generate the temporary clearing limit 52.
Furthermore, instead of selecting the direction of movement using the drive unit 60, it is possible to enter the simulation value which determines the temporary clearing limit 52 in the column of simulation setting values 54. Also in this case, the section of processing the clearing limit 42b similarly generates the temporary clearing limit 52 together with the input of the simulation value.
[0077] In conjunction with the generation of the temporary clearing limit 52 by moving section 52a, the calculation section of the removal count 42c calculates the yarn defect removal count. In other words, the generation of the temporary clearing limit 52 by moving the section 52a activates the calculation section of the removal count 42c for the automatic calculation of the yarn defect removal count without waiting for other instructions from the operator to calculate the count removal of yarn defects.
[0078] Together with the generation of the temporary clearing limit 52 by moving the section 52a and the calculation of the yarn defect removal count, the control section of the display 42d shows on the touch panel 41 the temporary clearing limit 52 which is generated in based on the displacement of section 52a and the count to remove the faults of the calculated yarn In other words, the generation of the temporary clearing limit 52 moving the section 52a and the calculation of the yarn defect removal count activate the control section of the display 42d for the automatic display on the touch panel 41 of the temporary clearing limit 52 and of the count to remove the defects of the calculated yarn without waiting for further instructions from the operator. Consequently, the operator can operate the drive unit 60 to move section 52a while looking at the touch panel 41, and can confirm the yarn defect removal count which has been modified based on the displacement of section 52a.
[0079] The section for processing the yarn clearing limit 42b sets the current clearing limit 52 or the temporary clearing limit 52 displayed on the touch panel 41 as a new clearing limit 52. The clearing limit 52 is set when the operator who confirmed the second result of the clearing simulation touches a button for selecting between the current clearing limit 52 and the temporary clearing limit 52.
[0080] Similarly to when the first clearing simulation is performed, the clearing limit processing section 42b can set the clearing limit 52 depending on whether the operator touches the Okay 71 button or the Cancel button 72. Consequently, the Okay 71 button is used to reflect the temporary clearing limit 52 in the actual yarn defect removal operation during the second clearing simulation, and the Cancel button 72 is used to discard the temporary clearing limit 52 and maintaining the current clearing limit 52 during the second clearing simulation.
[0081] The processing unit 42 can judge whether to perform the first clearing simulation or the second clearing simulation depending on which button prepared for the selection of the clearing simulation is touched. Alternatively, the processing unit 42 can carry out the first clearing simulation when the button 58 is touched during the selection of the section 52a which constitutes the clearing limit 52, and the second clearing simulation when the button 55 is touched.
[0082] As explained above, in the main control device 4, it is possible to select at least one section 52a from the plurality of sections 52a which constitutes the clearance limit 52. The main control device 4 generates the temporary clearing limit 52 in such a way that the yarn defect removal count to be removed in the selected section 52a reaches the entered target removal count, and displays the generated temporary clearing limit 52 on the touch panel 41. In this way, according to the main control device 4, can the clearing limit 52 to be displayed with which the yarn defect removal count to be removed in at least one section 52a between the plurality of the sections 52a which constitutes the yarn clearing limit 52 is set as the target removal count. Consequently, by selecting an objective section 52a and entering the objective removal count, the operator can confirm the clearance limit 52 in which the yarn defect removal count to be removed in the objective section 52a reaches the target removal count.
[0083] In the main control device 4, the current clearing limit 52 displayed on the touch panel 41 receives the selection of the section 52a which is touched between the plurality of the sections 52a. With this configuration, the operator can easily select a desired section 52a of the clearing limit 52.
[0084] In the main control device 4, the plurality of the buttons 58 displayed on the touch panel 41 receives the selection of the section 52a corresponding to the button 58 which is touched between the buttons 58. Similarly, in the main control device 4, the plurality of the buttons 55 displayed on the touch panel 41 receives the selection of the section 52a corresponding to the button 55 which is touched between the buttons 55. Consequently, the operator can easily select any minutely displayed section 52a of the clearance limit 52 as the desired section.
[0085] In the main control device 4, when the temporary clearing limit 52 is displayed on the touch panel 41 according to the objective removal count, the section 52a selected by the operator can be displayed so as to be distinguishable from the other sections 52a . Similarly, in the main control device 4, when the temporary clearing limit 52 generated according to the displacement of the section 52a is displayed on the touch panel 41, the section 52a selected by the operator can be displayed so as to be distinguishable from the other sections 52a . Consequently, the operator can easily identify the selected section 52a between the plurality of the sections 52a which constitutes the clearing limit 52.
[0086] Together with the selection of the section 52a and the acquisition of the objective removal count, the main control device 4 generates the temporary clearing limit 52 based on the target removal count, and displays the temporary clearing limit 52 on the panel tactile 41 in conjunction with the generation of the temporary clearance limit 52 based on the target removal count. Consequently, the operator can instantly confirm the temporary clearing limit 52 set according to the entered goal removal count.
[0087] The main control device 4 can select at least one section 52a between the plurality of the sections 52a which constitutes the clearance limit 52, and move the selected section 52a. In the present configuration, the drive unit 60 which moves the selected section 52a indicates the displacement directions for the clearance limit 52. Thus, the operator can intuitively move the selected section 52a in a desired direction of travel using the unit furthermore, based on the temporary clearing limit 52, the main control device 4 calculates the yarn defect removal count to be removed in the section 52a selected by the operator, and displays the removal count calculated on the touch panel 41. Consequently, the operator can identify the count to remove the yarn defects to be modified based on the displacement of the section 52a which constitutes the clearing limit 52, and the clearance limit 52 (the temporary clearing limit 52) generated after moving section 52a.
[0088] The drive unit 60 is displayed on the touch panel 41. Consequently, it is not necessary to provide a separate drive unit 60, and the drive unit 60 can be supplied to the operator at an appropriate time by displaying the same on the touch panel 41.
[0089] Together with the selection of the section 52a and the selection of the displacement direction using the drive unit 60, the main control device 4 moves the selected section 52a and generates the temporary clearing limit 52. Furthermore, the control device Main 4 calculates the yarn defect removal count together with the generation of the temporary clearing limit 52 by moving section 52a. Moreover, together with the generation of the temporary clearing limit 52 by moving the section 52a and the calculation of the yarn defect removal count, the main control device 4 displays the temporary clearing limit 52 and the defect count of the calculated yarn on the touch panel 41. In other words, when a displacement direction is entered for a section 52a which constitutes the clearance limit 52, the main control device 4 automatically displays the yarn defect removal count to be removed in section 52a for which has been entered the direction of movement and the limit of temporary clearing where the selected section 52a is moved. Consequently, the operator can instantly confirm the count to remove the yarn defects set according to the displacement of the section 52a which constitutes the clearing limit 52, and the temporary clearing limit 52 in which the selected section 52a is displaced.
[0090] In the main control device 4, the current clearing limit 52 and the temporary clearing limit 52 are displayed on the touch panel 41. Consequently, the operator can compare the current clearing limit 52 and the temporary clearing limit 52 .
[0091] In the main control device 4, the current clearing limit 52 or the temporary clearing limit 52 can be set as a new clearing limit 52. Consequently, the operator can set the current clearing limit 52 or the limit of temporary clearing 52 as a new clearing limit 52.
[0092] The yarn winding machine 1 comprises the feeding section of the yarn 21 which feeds a yarn; the winding section 24 which forms a bobbin winding the yarn; the yarn monitoring section 22 which monitors the yarn positioned between the yarn supply section 21 and the winding section 24 and detects the yarn defects; the junction section of the yarn 23 which joins the yarn coming from the feeding section of the yarn 21 and the yarn coming from the winding section 24 when the yarn is cut to remove the yarn defect detected by the monitoring section of the yarn 22, and the main control device 4. Since the yarn winding machine 1 comprises the main control device 4 explained above, the temporary clearing limit 52 previously explained can be displayed and the yarn defect can be adequately removed.
[0093] Exemplary embodiments of the present invention are explained above. However, the present invention is not limited to the embodiments explained above. For example, when the first clearing simulation is performed, the current clearing limit 52 need not be set previously. Alternatively, the temporary clearing limit 52 can be generated based on the yarn defect data stored in the storage unit 43 and the entered target removal count.
[0094] Duran LG 13. first clearing simulation and second clearing simulation, when a section 52a is selected as the target of the simulation, for example, sections 52a that are not the target can be selected by performing an operation such as touching the clearing limit 52, and the section 52a which is not touched and similar can be specified as the objective of the simulation.
[0095] In the above embodiments, the clearing limit 52 displayed on the touch panel 41 and the plurality of the buttons 58 act as the first input section that receives the selection of at least one section 52a between the plurality of the sections 52a which constitutes the clearing limit 52. However, a first input section which is constituted by a mechanical button and the like can be arranged separately from the touch panel 41. Similarly, the clearing limit 52 displayed on the touch panel 41 and the plurality of the buttons 55 act as second input section that receives the selection of at least one section 52a between the plurality of sections 52a which constitutes the clearance limit 52. However, a second input section which is constituted by a mechanical button and the like can be set up separately from the touch panel 41.
[0096] In the above embodiments, the drive unit 60 displayed on the touch panel 41 acts as a third input section that displays the displacement directions for the clearance limit 52 and receives the selection of these displacement directions. However, a third input section that consists of a mechanical button, a lever, and the like can be set up separately from the touch panel 41.
[0097] In the above embodiments, even if the plurality of the sections 52a which constitutes the clearing limit 52 corresponds to the plurality of the channels (types of the yarn defects), the plurality of the sections 52a can be based on any unit other than the channel.
[0098] In the aforesaid embodiments, the control section of the display 42d shows the defect of the yarn which remains on the yarn with the white round point and the defect of the yarn which is removed from the yarn with the black square point. However, the methods of displaying yarn defects are not limited to the white round point and the black square point, and these yarn defects can be viewed using other modes. For example, the control section of the display 42d can display the yarn defect remaining on the yarn with a green round dot and the yarn defect which is removed from the yarn with a red square stitch.
[0099] In the above embodiments, the main control device 4 of the yarn winding machine 1 acts as a device for setting the clearing limit, however a management device and the like arranged separately from the yarn winding machine 1 can act as a device for setting the clearing limit. Alternatively, a device for setting the yarn clearing limit for the yarn monitoring section 22 can be arranged along the main control device 4 in the base end part of the yarn winding machine 1. When the clearing limit setting device it is arranged separately from the main control device 4, separate display units can be arranged for the main control device 4 and the clearing limit setting device, or a common display unit (the touch panel 41) can be provided for the main control device 4 and the clearing limit setting device. Alternatively, the control device 22b of the yarn monitoring section 22 can transmit / receive data directly to / from the clearing limit setting device, or can transmit / receive data to / from the clearing limit setting device through the control device of the unit 3. When the control device 22b of the yarn monitoring section 22 transmits / receives the data directly to / from the clearing limit setting device, it is desirable to configure that the control device 22b of the The yarn monitoring section 22 can also transmit / receive data directly to / from the control device of the unit 3 which controls the yarn winding unit 2 on which the yarn monitoring section 22 is mounted.
[0100] Alternatively, in addition to the acquisition of the yarn defect data from the control device 22b of the yarn monitoring section 22, the processing unit 42 can acquire waveform data which is sent by the device of detection 22a of the yarn monitoring section 22. Alternatively, the processing unit 42 can only acquire the waveform data sent by the detection device 22a of the yarn monitoring section 22 without acquiring the yarn defect data from the control device 22b of the yarn monitoring section 22. In a similar configuration, the processing unit 42 can calculate the yarn defect data based on the acquired waveform data.
[0101] In the above embodiments, the main control device 4 performs both the first clearing simulation and the second clearing simulation. However, the execution of the second clearing simulation is not mandatory. When the main control device 4 displays the temporary clearing limit 52 on the touch panel 41, the display of the section 52a selected by the operator to be distinguishable from the other sections is not mandatory. Furthermore, it is not mandatory for the main control device 4 to display on the touch panel 41 the temporary clearing limit 52 together with the current clearing limit 52.
