Description

  The present invention relates to a creel and warper device that displays a defective yarn package.

  In general, a creel / warper device includes a warper that unwinds a yarn from a plurality of yarn packages attached to the creel and winds the yarn around a winding beam, a length measuring device that measures the winding length of the winding beam, and a yarn package. And a sensor that detects abnormality of the yarn that is unwound from the yarn package (for example, Patent Document 1).

JP-A-8-277069

  During operation, the creel / warper device draws yarn from each of hundreds to thousands of yarn packages provided on the creel, and winds the drawn yarn on a take-up beam in a state of being arranged in a sheet form.

  When the drawn yarn is cut, the sensor corresponding to the cut yarn outputs an abnormality detection signal to display to the operator the yarn package around which the cut yarn is wound.

  The creel / warper device stops the operation by detecting an abnormality detection signal, and restarts the operation after connecting the broken yarn by the yarn connecting device provided in the creel / warper device or by the operator's manual operation. .

  The creel / warper device can detect the yarn package around which the cut yarn is wound every time the yarn drawn from the yarn package is cut, but the yarn package is not judged how often the yarn is cut. It is not possible to determine whether or not a defective yarn package is wound with yarn that breaks frequently.

  If a defective yarn package having a high frequency of yarn breakage is attached to the creel / warper device, the winding efficiency of the creel / warper device is deteriorated.

  An object of the present invention is to accurately find and display a defective yarn package that causes frequent operation stoppages.

  A creel / warper device according to the present invention includes a warper that unwinds a yarn from a plurality of yarn packages attached to the creel and winds the yarn on a winding beam, and a length measuring device that measures the winding length of the yarn by the winding beam. And a sensor that is provided for each yarn package and that detects an abnormality of the yarn that is unwound from the yarn package, and further receives signals from the sensor and the length measuring device, A determination device that determines the quality of the yarn package based on a winding length in a period corresponding to the number of times of abnormality detection; and a display that displays the defective yarn package based on a failure determination signal from the determination device.

  According to the present invention, the creel / warper device determines the quality of the yarn package based on the number of abnormality detections of each yarn package and the winding length in a period corresponding to the number of abnormality detections. The quality of the yarn package is determined based on the frequency of cutting. As a result, it is possible to accurately identify the defective yarn package that causes frequent operation stop and display the identified yarn package on the display. Then, the operator can investigate and remove the cause of the defect determination with respect to the defective yarn package, or replace the defective yarn package with another yarn package, so that the operating efficiency of the creel / warper device can be improved. Since the winding length is based on an input signal from the length measuring device, it can be accurately obtained regardless of the operation speed. Therefore, it can respond to changes in the operating speed (for example, the speed cannot be increased depending on the yarn type, one of the outer layer part and inner layer part of the yarn package tends to be damaged, and the speed is changed depending on the unwinding position). Whether the yarn package is good or bad is determined.

  The determination device, when the abnormality detection signal is input, the winding length at the input time of the abnormality detection signal and the winding from the input time of the abnormality detection signal to the input time of the abnormality detection signal a predetermined number of times before The quality of the yarn package may be determined based on the length. Since the yarn package is determined when the abnormality detection reaches a predetermined number of times, the yarn package in which the abnormality is frequently detected is quickly determined to be defective, and it is possible to avoid a reduction in the operating rate. Further, the determination device determines when an abnormality is detected. Specifically, since the determination is performed when the abnormality is detected and the creel / warper device is in a stopped state, the cause of the yarn package failure determination based on the failure determination display is determined. Difficult work can continue to be performed during operation such as replacement.

  After the determination device determines that the yarn package is good, the determination device may further determine whether the yarn package is good or not at each subsequent input time point of the abnormality detection signal. This is performed based on the winding length at the input time point and the winding length at the input time point of the abnormality detection signal a predetermined number of times before the input time point of the abnormality detection signal. Even if the yarn package is determined to be good, a series of operations for detecting and determining abnormality is continued, so that the inner layer portion can cope with a defective yarn package. Even after the yarn package is determined to be good, the yarn package is determined at each abnormality detection time point, so that the defective yarn package is quickly extracted.

  After determining that the yarn package is good, the determination device further erases the storage of the winding length at the time of the input of the abnormality detection signal in the yarn package, and the number of times exceeding the predetermined number of times from the memory erasure. When the abnormality detection signal is input, based on the winding length at the input point of the abnormality detection signal and the winding length at the input point of the abnormality detection signal a predetermined number of times before the input point of the abnormality detection signal, The quality of the yarn package may be determined. Even if the yarn package is determined to be good, a series of operations for detecting and determining abnormality is continued, so that the inner layer portion can cope with a defective yarn package.

  The determination device may determine the quality of the yarn package based on an abnormality detection signal generated after a predetermined operation period has elapsed from the start of operation. For a while from the start of operation, the sensor may detect an abnormality due to a cause such as a yarn catching error or damage to the surface of the yarn package. Abnormality detection due to the reason that the yarn package is not defective is eliminated, and the determination device accurately determines the quality of the yarn package.

  In this embodiment, the red light indicates that there is an abnormal yarn package 14 to be replaced, and the yellow light indicates that there is an abnormal yarn package 14 that does not need to be replaced but needs to be repaired like a yarn splicing. Show.

  As will be described later, the warper 20 includes a yarn package determination device 30, a length measurement device 38, a determination reference length setting device 44, a determination number setting device 46, a storage device 32, an operation control device 34, and a monitoring device. A start circuit 36 and a monitoring start length setting unit 45 are included.

  The yarn package determination device 30 is connected to the determination reference length setting unit 44 and the determination reference number setting unit 46 so as to receive the determination reference length L and the determination reference number N set therein, and the operation control device. 34 and the operation start command circuit 36 are connected to receive the winding length Z and the monitoring start command signal S6 output from them.

  The determination reference length L is used as a reference for determining the winding length of the yarn 16 onto the winding beam 18 when determining the quality of the yarn package 14. The determination reference number N is used as a reference for determining the number of times of abnormality detection of the yarn 16 when determining the quality of the yarn package. The winding length Z is a value representing the length of the yarn 16 wound around the yarn package 18 and is stored in the storage device 32. The monitoring start command signal S6 is a command signal for starting monitoring of the quality of the yarn package 14.

  The monitoring start length setting unit 45 includes a winding length that the yarn package determination device 30 does not use to determine the quality of the yarn package 14, in other words, from the start of operation of the creel / warper device 10 to the yarn package determination device 30. The winding length until the start of validating the yarn breakage information of the yarn package 14 is set by the operator. The set winding length is set as the monitoring start length Ls.

  The warper 20 includes a replacement package reset switch SW1, an all-package reset switch SW2, and a winding length reset switch SW3 in order to reset the winding length stored in the storage device 32.

  The replacement package reset switch SW1 and the all package reset switch SW2 are both connected to the yarn package determination device 30. The winding length reset switch SW3 is connected to the operation control device 34.

  The operation control device 34 receives the winding length reset signal S5 from the winding length reset switch SW3 and the count value Cn from the length measurement counter 42 of the length measuring device 38. It is connected to SW3 and length measurement counter 42.

  The operation control device 34 also outputs the winding length Z to the yarn package determination device 30 and the winding length reset signal S5 for resetting the winding length to the monitoring start command circuit 36, respectively. It is connected.

  The monitoring start command circuit 36 is further connected to the monitoring start length setting unit 45 and the operation control device 34 so as to receive the monitoring start length Ls and the winding length Z of the monitoring start length setting unit 45. .

  The operation of each component of the creel / warper apparatus 10 will be described below.

  When any of the sensors 22 detects that the yarn 16 does not exist in the detection area of the sensor 22, the sensor 22 outputs a yarn abnormality detection signal S1 to the yarn package determination device 30 of the warper 20.

  As the sensor 22, an optical yarn break detector that detects breakage of the yarn 16 due to cutting and consumption can be used. In this case, the yarn abnormality detection signal S1 is a signal representing abnormality of the yarn 16 due to yarn breakage.

  However, in addition to such a sensor 22, it is possible to use a sensor of a type that detects an abnormality of the yarn 16 without yarn breakage due to a knot or large fluff, etc. In addition to such a function, yarn breakage is detected. Possible sensors can be used. By doing so, it is possible to detect an abnormal state due to yarn breakage and an abnormal state without yarn breakage.

  The abnormal state without yarn breakage refers to a state where knots are formed on the yarn, a state where large fluff is generated on the yarn, and the like. Under these conditions, the yarn abnormality detection signal S1 is generated when a knot or fluff passes through the detection region of the sensor.

  The replacement package reset switch SW1 is operated by the operator when the yarn package 14 supported by the peg 28 is replaced with a new yarn package 14.

  When the replacement package reset switch SW1 is operated, the replacement package reset switch SW1 causes the yarn package determination device 30 to output a replacement package reset signal S3 to the storage device 32 via the yarn package determination device 30. The storage device 32 sets the stored value of the winding length Z corresponding to the replaced yarn package 14 to 0 by the replacement package reset signal S3.

  All package reset switches SW2 are operated automatically or manually before the start of operation, simultaneously with the start of operation, simultaneously with the end of operation, or after the end of operation. In the embodiment, it is manually operated and operated by an operator before starting operation.

  When the all package reset switch SW2 is operated, the all package reset switch SW2 outputs the all package reset signal S4 to the storage device 32 via the yarn package determination device 30. The storage device 32 receives all the package reset signals S4, thereby erasing all stored yarn packages 14 stored in the previous operation, that is, erasing all registered yarn packages 14. .

  The winding length reset switch SW3 is operated automatically or manually before the start of operation, simultaneously with the start of operation, simultaneously with the end of operation, or after the end of operation. In the embodiment, it is manually operated and operated by an operator before starting operation. When the winding length reset switch SW3 is operated, the winding length reset switch SW3 turns the winding length to reset the winding length of the monitoring start command circuit 36 via the operation control device 34. A reset signal S5 is output.

  The length measuring device 38 includes a length measuring roll 24, an encoder 40 that generates a pulse signal S7 every time the length measuring roll 24 rotates by a predetermined angle, and a length measuring counter 42 that counts the pulse signal S7 output from the encoder 40. And have. The length measurement counter 42 outputs the count value Cn to the operation control device 34.

  The operation control device 34 obtains the length of the yarn 16 wound around the take-up beam 18 based on the count value Cn from the length measuring device 38, and uses the obtained value for the take-up length of the yarn 16 around the take-up beam 18. Is output to the yarn package determination device 30 and the monitoring start command circuit 36.

  The monitoring start command circuit 36 outputs a monitoring start command signal S6 to the yarn package determination device 30 based on the winding length Z of the winding beam 18 and the monitoring start length Ls from the monitoring start length setting unit 45. To do.

  The operation control device 34 outputs the calculated winding length Z to the yarn package determination device 30.

  The monitoring start command circuit 36 determines the monitoring start command signal S6 as a yarn package based on the winding length Z from the operation control device 34 and the monitoring start length Ls set in the monitoring start length setting unit 45. Output to device 30.

  The yarn package determination device 30 identifies the yarn package 14 that no longer detects the yarn 16 based on the yarn abnormality detection signal S1 from the sensor 22 corresponding to the yarn package 14.

  The yarn package determination device 30 outputs a display signal S2 to the indicators 26 and 48 to display the yarn breakage, and executes the steps to be described later. In order to notify, a display signal S22 indicating abnormality, that is, a defect is output to the indicators 26 and 48.

  The determination reference length setting unit 44 outputs a determination reference length L preset by the operator to the yarn package determination device 30. The determination reference number setting unit 46 outputs a determination reference number N preset by the operator to the yarn package determination device 30.

  The determination reference number N is a numerical value that is referred to when determining whether or not to determine whether the yarn package in which an abnormality has been detected is acceptable. More specifically, when the abnormality detection count Y representing the number of detections of abnormality of the yarn package in which the abnormality is detected becomes equal to or greater than the determination reference count N as the determination criterion, the quality of the yarn package is determined. Used for.

  The abnormality detection count Y indicates that each time an abnormality of the yarn 16 from the yarn package 14 is detected, a yarn abnormality signal is supplied to the storage device 32 via the yarn package determination device 30 for each yarn package 14. It is obtained for each yarn package 14 by counting every time. The first abnormality detection signal is used to register the yarn package number X of the yarn package 14 in the storage device 32.

  The all-package indicator 48 is disposed on the operation panel of the warper and is connected to the yarn package determination device 30 and can correspond to all the yarn packages 14 attached to the creel 12. While displaying so that the yarn package number X of the package 14 can be specified, when it is determined that the yarn package 14 is defective, a red light is lit or blinked.

  The storage device 32 is connected to the yarn package determination device 30, and outputs from the yarn package determination device 30 the winding length Z for each yarn break in the yarn package 14 of the yarn package number X and the number of times Y of abnormality detection. This is stored for each yarn package 14 based on the yarn abnormality detection signal S1.

  The storage device 32 also registers the yarn package number X corresponding to the replaced yarn package 14 as described above by the replacement package reset signal S3 output from the replacement package reset switch SW1 via the yarn package determination device 30. Is erased (reset).

  The storage device 32 further erases the registration of the yarn package numbers X of all the yarn packages 14 as described above by the all package reset signal S4 output from the all package reset switch SW2 via the yarn package determination device 30. (Reset).

  In the creel / warper device 10, the sheet-like yarn 16 is removed by changing the operating speed of the creel / warper device 10, the change in the winding diameter of the yarn 16 wound around the take-up beam 18, or the change in the rotation speed of the take-up beam 18. Even if the feeding speed changes, the length measuring device 38 obtains the winding length based on the signal from the encoder 40 that measures the rotation of the length measuring roller 24, so that the exact winding length can be obtained. .

  As shown in FIGS. 4 to 6, the creel / warper apparatus 10 operates. In the following description, the operation of one yarn package 14 will be described as a representative, but actually, the operation of the creel / warper device 10 is performed for each yarn package 14.

  FIG. 4 is a timing chart showing the state of the Xm yarn package 14 among the plurality of yarn packages 14 (yarn package numbers X1 to Xm) attached to the creel 12. 5 and 6 are flowcharts for explaining the operation of the creel / warper apparatus 10.

  [Work before starting operation]

  First, the operator depresses all the package reset switches SW2 and the winding length reset switch SW3 prior to the start of operation.

  Accordingly, the yarn package determination device 30 deletes the registration of the yarn package numbers X of all the yarn packages 14 stored in the storage device 32 by receiving the all package reset signal S4.

  [Normal operation status]

  Next, the operator operates an operation start switch (not shown) to start the operation of the creel / warper device 10 and rotates the take-up beam 18.

  The winding beam 18 pulls the yarn 16 from the yarn package 14 and winds the drawn yarn 16. At this time, as shown in the column of “yarn package number Xm” in FIG. 4, the yarn package 14 of A is attached to the creel 12 as the yarn package number Xm.

  The length measuring counter 42 of the length measuring device 38 counts the pulse signal S7 output from the encoder 40 along with the rotation of the length measuring roll 24, and gives a count value Cn representing the number of counted pulse signals to the operation control device 34. Output.

  The monitoring start command circuit 36 determines whether or not the winding length Z from the operation control device 34 is larger than the monitoring start length Ls set in the monitoring start length setting unit 45, and the two match. At this time, a monitoring start command signal S6 is output to the yarn package determination device 30.

  When the yarn abnormality detection signal S1 is input from the sensor 22 to the yarn package determining device 30 while the creel / warper device 10 is winding the yarn 16 on the winding beam 18, the yarn package determining device 30 cuts the yarn 16. For example, the display signal S2 is output to the display 26 corresponding to the yarn abnormality detection signal S1, and the operation of the creel / warper device 10 is temporarily stopped.

  The yarn package determination device 30 turns on the yellow light of the indicator 26 corresponding to the yarn package group to which the yarn package number Xm belongs in order to inform the operator of the position of the yarn package where the abnormality is detected.

  The yarn package determination device 30 executes the steps shown in FIGS. 5 and 6 every time the yarn abnormality detection signal S1 is detected. Hereinafter, the operation of the yarn package determination device 30 when the yarn abnormality detection signal S1 is detected at the timing shown in the column of “yarn abnormality detection signal S1” in FIG. 4 will be described.

  [When there is a first yarn abnormality detection signal S1]

  In this case, in the example shown in FIG. 4, the first yarn abnormality detection signal S1 is generated after the start of operation and before the start of quality monitoring. For this reason, as will be described below, the yarn package determination device 30 executes the steps ST001-ST002-ST003-ST007 shown in FIG.

  First, the yarn package determination device 30 detects the yarn abnormality detection signal S1 of the sensor 22 corresponding to the yarn package number Xm (ST001). By this detection, the yarn package determination device 30 outputs an operation stop command signal S8 to the operation control device 34, stops the rotation of the winding beam 18 with a braking force, and temporarily stops the winding of the yarn 16.

  Next, the yarn package determination device 30 determines whether or not the monitoring start command signal S6 is received (ST002).

  At the above time, as shown in FIG. 4, since the winding length Zm converted from the coefficient value Cn has not reached the monitoring start length Ls, the monitoring start command circuit 36 does not output the monitoring start command signal S6. . Therefore, the yarn package determination device 30 determines that the monitoring start command signal S6 has not been received, and executes step ST003.

  Next, the yarn package determination device 30 invalidates the received yarn abnormality detection signal S1 (ST003).

  Then, the yarn package determination device 30 outputs a display signal S2 that is lit in yellow indicating that any one of the yarn packages 14 belonging to the package group corresponding to the yarn abnormality detection signal S1 is abnormal to the corresponding indicator 26. And it waits until an operator operates a driving | operation start switch (ST007).

  Based on the fact that the indicator 26 is lit in yellow while the creel / warper device 10 is stopped, the operator can detect the yarn package 14 corresponding to the yarn abnormality detection signal S1 and the cause of the abnormality (for example, Thread miss) is specified.

  After removing the cause of the abnormality, the operator operates the operation start switch to restart the operation of the creel / warper device 10 in order to restart the operation of winding the yarn 16 around the winding beam 18.

  As described above, when the predetermined operation period has not elapsed from the start of operation, the yarn package determination device 30 invalidates the yarn abnormality detection signal S1 and uses it to determine whether or not the yarn package is good (step ST012 described later). Not in.

  In other words, the yarn package determination device 30 notifies the operator of the yarn package 14 in which an abnormality has been detected by the indicators 26 and 48 during a predetermined operation period from the start of operation, but a yarn hooking error, damage to the surface of the yarn package, etc. The yarn package 14 is not judged to be good or bad by using the yarn abnormality detection signal S1 that is output along with the cause of the initial abnormality.

  [When there is a second yarn abnormality detection signal S1]

  In this case, as shown in FIG. 4, the yarn package determination device 30 detects the second yarn abnormality detection signal S1 from the start of operation after the start of monitoring. Therefore, the yarn package determination device 30 detects the second yarn abnormality detection signal S1 as the first abnormality detection signal after the start of monitoring (ST001).

  For this reason, the yarn package determination device 30 detects the first yarn abnormality detection signal S1 after the start of monitoring, and as described below with reference to FIG. 5, ST001-ST002-ST004-ST005-ST006-ST007. Perform the steps.

  The yarn package determination apparatus 30 executes step ST002 after executing step ST001. At this time, as shown in FIG. 4, since the winding length Z when the second yarn abnormality detection signal S1 is generated exceeds the monitoring start length Ls, the monitoring start command circuit 36 The start command signal S6 is output to the yarn package determination device 30.

  Therefore, the yarn package determination device 30 determines in step ST002 that the monitoring start command signal S6 has been output, and determines whether the yarn package 14 is good or bad based on the yarn abnormality detection signal S1. I do.

  Next, the yarn package determination device 30 determines whether or not the registration about the yarn abnormality detection signal S1 of the yarn package number Xm stored in the storage device 32 has already been performed (ST004).

  As described above, since the registration of the yarn package number Xm stored in the storage device 32 has been deleted due to the work before the start of operation by the operator, the yarn package determination device 30 determines in step ST004 that the yarn package number Xm. It is determined that there is no registration about the presence of the yarn abnormality detection signal S1. In other words, it is determined that the first yarn abnormality detection signal S1 is detected in the yarn package 14 of A.

  Next, as shown in the “Xm registration” column in FIG. 4, the yarn package determination device 30 records, or registers, in the storage device 32 that the yarn package number Xm has been detected as abnormal. As shown in the column “Detection Count Ym”, the abnormality detection count Ym is set to “0” (ST005).

  Next, the yarn package determination device 30 stores the winding length Z output from the operation control device 34 in the storage device 32 as the winding length Zm0 of the yarn package number Xm when the abnormality detection count Ym is 0. (ST006).

  Then, the yarn package determination device 30 executes step ST007 described above. The operator investigates the cause of the yarn 16 in which the abnormality is detected, removes the abnormality cause of the yarn 16 in which the abnormality is detected, and restarts the operation of the creel / warper device 10.

  [When there is a third to fifth yarn abnormality detection signal S1]

  In this case, as shown in FIG. 4, when the third to fifth yarn abnormality detection signals S1 from the start of operation are detected, the number of abnormality detections Ym is 1 to 3, so the number of abnormality detections Ym is a criterion. The number of times is less than N (4 in this embodiment). Therefore, the yarn package determination device 30 executes the steps ST001-ST002-ST004-ST008-ST009-ST010-ST007 described below with reference to FIGS.

  First, when the third to fifth yarn abnormality detection signal S1 is generated, the yarn package number Xm is already registered. For this reason, the package determination apparatus 30 determines in step ST004 in FIG. 5 that the yarn package number Xm is registered, and proceeds to step ST008 in FIG.

  In step ST008, the yarn package determination device 30 adds 1 to the value of the abnormality detection count Ym for the yarn package Xm, and stores the added abnormality detection count Ym in the storage device 32 (ST008). In this way, the yarn package determination device 30 records, in the storage device 32, the number of times that the yarn abnormality detection signal S1 after the start of monitoring and after registration of the yarn package number Xm is detected for the yarn package A.

  Next, the yarn package determination device 30 stores the winding length Z output from the operation control device 34 in the storage device 32 as the winding length Zmn at the abnormality detection count Ym (ST009). Here, n in Zmn is the value of Ym. By this step ST009, the value of the winding length Z when the yarn abnormality detection signal S1 is detected is stored in the storage device 32.

  Next, the yarn package determination device 30 determines whether or not the abnormality detection count Ym of the yarn package number Xm in which an abnormality has been detected is the determination reference count N abnormality set in the determination reference count setting unit 46 (ST010).

  Since the value of the abnormality detection number Ym is 1 to 3 at the time of execution of step ST009, the yarn package determination device 30 determines that the abnormality detection number Ym has not reached the determination reference number N, and in FIG. Step ST007 is executed.

  Thus, the yarn package determination device 30 detects the yarn abnormality detection signal S1 when the value of the abnormality detection number Ym is 0 to 3, in other words, when the abnormality detection number Ym has not reached the determination reference number N. Even if the determination is made, it is not determined whether the yarn package 14 is defective (ST012) (the “determination execution” column in FIG. 4 is empty).

  [When there is a sixth to eighth yarn abnormality detection signal S1]

  In this case, as shown in FIG. 4, when the yarn package determination device 30 detects the sixth to eighth yarn abnormality detection signal S1, the abnormality detection frequency Ym is 4 to 6, and the value of the abnormality detection frequency Ym is 4-6. Is equal to or greater than the determination reference number N. In addition, a value of an expression Zmn−Zm (n−N) described later (hereinafter referred to as “determination target winding length”) exceeds the determination reference length L.

  Therefore, the yarn package determination apparatus 30 executes the steps ST001-ST002-ST004-ST008-ST009-ST010-ST011-ST012-ST007 shown in FIGS.

  First, the yarn package determination device 30 determines in step ST010 that Ym is greater than or equal to N, and proceeds to step ST0011.

  Next, the yarn package determination device 30 determines the winding length Zmn of the yarn 16 when the abnormality detection count Ym is n, and the winding length Zm of the yarn 16 when the abnormality detection count Ym is (n−N) ( n−N), that is, the determination target winding length is calculated by the following equation (1) (ST011).

  Judging length for determination = Formula Zmn−Zm (n−N) (1)

  Next, the yarn package determination device 30 determines whether or not the determination target winding length calculated by the equation (1) exceeds the determination reference length L (ST012).

  As shown in FIG. 4, the determination target winding length calculated by the equation (1) at the time when the sixth to eighth yarn abnormality detection signals S1 are present exceeds the determination reference length L. .

  For this reason, the yarn package determination device 30 determines that the yarn package 14 of A is good in step ST012 (see the “determination result” column in FIG. 6), and does not output the defective display signal S22.

  Then, the yarn package determination device 30 stands by until there is an operator's operation resumption operation (ST007).

  As described above, when the abnormality detection count Ym is 4 to 6 in FIG. 4, the yarn package determination device 30 determines that the abnormality detection frequency of the yarn package Xm per determination reference length L is low. For this reason, the yarn package determination device 30 determines that the yarn package number Xm in which the abnormality is detected, that is, the yarn package 14 of A, is good, but does not light the red light indicating that the yarn package 14 is defective on the display 26. Turn on only the yellow light indicating abnormality.

  More specifically, as shown in FIG. 4, when the abnormality detection count Ym of the yarn abnormality detection signal S1 is 4, the yarn package determination device 30 performs the first determination (ST012). The winding length to be judged at this time is the winding length Zm4 detected when the abnormality detection count Ym is 4, and the winding detected when the determination reference detection count N is subtracted from the current abnormality detection count Ym. This is the difference from the length Zm (4-N). The winding length Zm (4-N) is the same as the winding length Zm0 detected when the abnormality detection count Ym is zero. For this reason, the yarn package determination device 30 determines that the determination target winding length exceeds the determination reference length L, and determines that the yarn package 14 of A is good (the column “determination result” in FIG. 4). reference).

  [When there is a ninth yarn abnormality detection signal S1]

  In this case, as shown in FIG. 4, when the yarn package determination device 30 detects the ninth yarn abnormality detection signal S1 from the start of operation, the abnormality detection number Ym is 7, and the value of the abnormality detection number Ym is 7 Is equal to or greater than the determination reference number N. Further, a value of an expression Zmn−Zm (n−N) described later, that is, a determination target winding length is equal to or less than the determination reference length L.

  For this reason, the yarn package determination device 30 executes the steps ST001-ST002-ST004-ST008-ST009-ST010-ST011-ST012-ST013-ST014-ST015-ST016-ST007 shown in FIGS.

  First, in step ST012, the yarn package determination device 30 determines that the result calculated by the equation (1) is equal to or less than the determination reference length L (see the “determination result” column in FIG. 4), and then the yarn package number. Xm, that is, the yarn package 14 of A is determined as a defective yarn package.

  More specifically, as shown in FIG. 4, when the abnormality detection count Ym of the yarn package 14 is 7, the yarn package determination device 30 performs the fourth determination (ST012).

  The winding length to be judged at this time is the winding length Zm7 detected when the abnormality detection number Ym is 7, and the abnormality detection number Ym subtracts the determination reference detection number N from the current abnormality detection number Ym. This is a value obtained by the difference from the winding length Zm (7-N) detected when the operation is performed (see the column of “determination target winding length” in FIG. 4). The winding length Zm (7-N) is the same as the winding length Zm3 detected when the abnormality detection count Ym is 3.

  As a result, in step ST012, the yarn package determination apparatus 30 determines that the determination target winding length is equal to or less than the determination reference length L, and in step ST013 determines that the yarn package 14 of A is defective (FIG. 4 (refer to the column of “judgment result”).

  Next, the yarn package determination device 30 outputs a display signal S22 indicating a failure to the display 26 of the creel 12 in order to inform the operator of the yarn package number Xm determined to be a defective yarn package.

  The indicator 26 corresponding to the yarn package number Xm turns on a red lamp indicating a defect based on the display signal S22 (ST013). Since the red light of the indicator 26 is lit, the operator can easily identify the yarn package number Xm determined as defective, that is, the yarn package 14 of A.

  Next, as shown in the “package number Xm” column of FIG. 4, the operator removes the yarn package 14 determined to be defective, and causes the peg 28 to support the yarn package 14 and replaces the yarn package 14. (ST014).

  Next, the operator operates the replacement package reset switch SW1 after the replacement of the yarn package 14 is completed (ST015). As a result, the replacement package reset signal S3 output from the replacement package reset switch SW1 is input to the yarn package determination device 30.

  The yarn package determination device 30 deletes the registration of the yarn package number Xm stored in the storage device 32 (see the “abnormality detection times Ym” and “Xm registration” columns in FIG. 4).

  Next, the yarn package determination device 30 stops the output of the display signal S22 output to the display device 26 so as to turn off the red light indicating the failure of the display device 26 (ST016).

  The yarn package determination device 30 stands by until there is an operator's operation resumption operation (ST007).

  [When there is a tenth yarn abnormality detection signal S1]

  In this case, as shown in FIG. 4, the yarn abnormality detection signal S1 detected by the yarn package determination device 30 for the tenth time from the start of operation is first detected after the yarn package 14 is replaced.

  As described above, the registration of the yarn package number Xm stored in the storage device 32 is deleted in step ST015 when the yarn package 14 is replaced. Therefore, the yarn package determination device 30 determines in step ST004 that the yarn package number Xm is not registered.

  The yarn package determination apparatus 30 executes steps ST001-ST002-ST004-ST005-ST006-ST007 as described below with reference to FIG.

  [When there are 11th to 13th yarn abnormality detection signals S1]

  The yarn package determination device 30 executes Steps ST001-ST002-ST004-ST008-ST009-ST010-ST007 described when the third to fifth yarn abnormality detection signals S1 are detected.

  [When there are 14th and 15th yarn abnormality detection signals S1]

  The yarn package determination apparatus 30 executes Steps ST001-ST002-ST004-ST008-ST009-ST010-ST011-ST012-ST007 described when the sixth to eighth yarn abnormality detection signals S1 are detected.

  As described above, the yarn package 14 is judged to be good or bad when the abnormality detection count Ym reaches a predetermined determination reference count N. Therefore, the yarn package 14 in which abnormalities are frequently detected is quickly determined to be defective. It is possible to avoid a reduction in operating rate. The yarn package determination device 30 determines when an abnormality is detected. Specifically, the yarn package determination device 30 determines when the abnormality is detected and the creel / warper device 10 is in a stopped state. It is possible to continue to perform difficult tasks during operation such as investigating the cause of failure determination and replacement.

  Further, even if the yarn package 14 is determined to be good, a series of operations for detecting and determining abnormality is continued, so that the inner layer portion can cope with the defective yarn package 14. Further, even after the yarn package 14 is determined to be good, the yarn package 14 is determined at each abnormality detection time point. Therefore, the defective yarn package 14 is quickly replaced, and a reduction in operating rate is suppressed.

  The yarn package determination device 30 determines pass / fail of the yarn package 14 based on the yarn abnormality detection signal S1 generated after a predetermined operation period has elapsed from the start of operation. In this embodiment, the yarn package determination device 30 determines a predetermined value from the start of operation. The operation start period is set by the monitor start length setting unit 45 from the start of operation until the monitoring start length Ls is wound up. However, the predetermined operation period from the start of operation may be set directly using a timer. That is, the timer is set to 60 seconds, for example, and the yarn abnormality detection signal S1 output for 60 seconds from the start of operation is invalidated. Further, in the case of low speed operation and thin yarn, the yarn abnormality detection signal S1 after the yarn 16 on the surface of the yarn package 14 is unwound reliably is made effective by setting the timer setting time longer than 60 seconds. And used for pass / fail judgment.

  In the present embodiment, the yarn package number X is registered in the storage device by registering only the yarn package number X of the yarn package 14 in which the yarn breakage has occurred, and the yarn package number X is not registered unless the yarn breakage has occurred. Therefore, the storage device does not require an extra storage capacity and the number of registrations is small, so that the yarn package determination device 30 can quickly read the information of the corresponding yarn package number X.

  In this embodiment, when the yarn abnormality signal S1 is output for the first time, the yarn package number X is registered and the occurrence of the abnormality is not written, but the yarn package number X is registered in the storage device 32. An error occurrence may be written. In this case, the abnormality detection count Ym is treated as 1 in the first yarn abnormality signal S1, and is treated as 2, 3,... In the second and subsequent yarn abnormality signals S1. If the determination reference number N is set to 5 instead of 4, it is determined whether the yarn package 14 is good or bad at the same level as in this embodiment.

  In this embodiment, the sensor 22 is a yarn breakage detector, but a sensor that can detect a defect of the yarn 16 such as a large knot or a large fluff due to a yarn splicing failure in the previous process may be used in combination. Due to the defect of the yarn 16, even if the unwinding defect occurs in the yarn package 14 and the yarn breakage does not occur, if such a knot or fluff passes through the detection region of the sensor, it is detected mechanically or optically. Then, the yarn abnormality detection signal S1 is output, and a cutting device is provided depending on the sensor to cut the yarn 16. The operation is stopped, such knots and fluff are removed, and opening defects in the loom and weaving defects of the woven fabric are prevented.

  [Example 2]

  7 and 8 show a modification of the creel / warper apparatus 10 shown in FIG. FIG. 7 shows a creel / warper device 52 provided with an allowable abnormality detection ratio setting device 50 instead of the determination reference length setting device 44 shown in FIG. In FIG. 8, steps ST011 and ST012 are replaced with steps ST011 'and ST012' in the operation of the yarn package determination device 30 of FIG.

  The allowable abnormality detection ratio setting unit 50 outputs a preset allowable abnormality detection ratio value A to the yarn package determination device 30. In the allowable abnormality detection ratio setting unit 50, an allowable abnormality detection ratio value A that is a value obtained by dividing the determination reference number N by the determination reference length L is set. The allowable abnormality detection ratio value A means the number of detections of the yarn abnormality detection signal S1 per unit length.

  First, when the yarn count determination device 30 determines in step ST010 described in the first embodiment that the determination count Ym is equal to or greater than the determination reference count N, the yarn package determination device 30 represents the frequency of occurrence of an abnormality as a ratio of abnormality detection per winding length. An abnormality detection ratio value is calculated by the following equation (2) (ST011 ′).

  Abnormality detection ratio value = N / {Zmn−Zm (n−N)} (2)

  Next, the yarn package determination device 30 determines whether or not the abnormality detection ratio value calculated by the equation (2) is larger than the allowable abnormality detection ratio value A (ST012 '). When the yarn package determination device 30 determines that the abnormality detection ratio value is larger than the allowable abnormality detection ratio value A, the yarn package determination device 30 executes step ST013 described in the first embodiment. Step ST007 is executed.

  [Example 3]

  The creel / warper apparatus 10 according to the third embodiment will be described with reference to FIGS. 9 and 10. The creel / warper apparatus 10 of the third embodiment has the same configuration as shown in FIG. 9 and 10 respectively judge the quality of the yarn package 14 based on the yarn abnormality detection signal S1 generated after a predetermined operation period has elapsed from the start of the winding operation of the yarn 16 onto the winding beam 18. A timing chart and a flow chart are shown.

  In FIG. 10, step ST009 is omitted in the operation of the yarn package determination device 30 of FIG. 6, and steps ST010, ST011, and ST012 are replaced with steps ST010 ′, ST011 ″, and ST012 ″.

  [When there are first and second yarn abnormality detection signals S1]

  When the yarn package determination device 30 detects the first yarn abnormality detection signal S1 counting from the start of operation, the yarn package determination device 30 executes the steps ST001-ST002-ST003-ST007 described with reference to FIG. When the yarn package determination device 30 detects the second yarn abnormality detection signal S1 counting from the start of operation, the yarn package determination device 30 executes the steps ST001-ST002-ST004-ST005-ST006-ST007 described with reference to FIG.

  [When there is a third to fifth yarn abnormality detection signal S1]

  As shown in FIG. 9, the number of abnormality detections Ym when the yarn package determination device 30 detects the third to fifth yarn abnormality detection signals S1 from the start of operation is 1 to 3. That is, the abnormality detection count Ym is not the determination reference count N (4 in this embodiment). Therefore, the yarn package determination apparatus 30 executes the steps ST001-ST002-ST004-ST008-ST010'-ST007 described below with reference to FIGS.

  First, when the yarn package determination device 30 receives the yarn abnormality detection signal S1, after executing steps ST001-ST002-ST004, as shown in the column of “abnormality detection number Ym” in FIG. 1 is added to (ST008).

  Next, the yarn package determination device 30 determines whether the abnormality detection count Ym of the yarn abnormality detection signal S1 and the determination reference count N have the same value (ST010 '). In the example of FIG. 9, the abnormality detection count Ym is 1 to 3, which is different from the determination reference count N. Therefore, the yarn package determination device 30 determines that the condition is not satisfied, and executes step ST007.

  [When there is a sixth yarn abnormality detection signal S1]

  As shown in FIG. 9, the abnormality detection count Ym is 4 when the yarn package determination device 30 detects the sixth yarn abnormality detection signal S1 from the start of operation. That is, the abnormality detection count Ym is the same as the determination reference count N. Further, the value obtained by the equation (3) described later, that is, the determination target winding length exceeds the determination reference length L.

  Judging length for determination = Zmn−Zm0 (3)

  For this reason, the yarn package determination apparatus 30 executes the steps ST001-ST002-ST004-ST008-ST010'-ST011 "-ST0012" -ST016-ST007 described below with reference to FIGS. .

  First, the yarn package determination device 30 that has executed Step 008 determines whether the abnormality detection count Ym of the yarn abnormality detection signal S1 and the determination reference count N are the same value (ST010 '). In the example of FIG. 9, the abnormality detection count Ym is 4, which is the same as the determination reference count N. Therefore, the yarn package determination device 30 determines that the condition is satisfied, and executes step ST011 ″.

  Next, the yarn package determination device 30 calculates the difference from the winding length Zm0 to the current winding length Zmn when the first abnormality of the yarn package number Xm is detected, that is, the determination-target winding length by the equation (3). It is calculated by (Zmn−Zm0) (ST011 ″).

  Next, the yarn package determination device 30 determines whether or not the determination target winding length calculated from Expression (3) is equal to or less than the determination reference length L (ST012 '').

  At this time, as shown in FIG. 9, the determination target winding length calculated by the equation (2) when the sixth yarn abnormality detection signal S1 is present exceeds the determination reference length L. Therefore, the yarn package determination device 30 determines that the yarn package A is good (see the “determination result” column in FIG. 9), and does not output the defective display signal S22.

  Next, the yarn package determination device 30 deletes the registration of the yarn package number Xm stored in the storage device 32 as shown in the “Xm registration” column of FIG. 9 (ST016).

  The yarn breakage display by the display 26 is canceled when the yarn 16 is connected and repaired, and the yarn abnormality detection signal S1 from the sensor 22 stops and the display is canceled.

  Next, the yarn package determination device 30 stands by until there is an operator's operation resumption operation (ST007).

  [When there is a seventh yarn abnormality detection signal S1]

  As shown in FIG. 9, the yarn abnormality detection signal S1 detected by the yarn package determination device 30 for the seventh time from the start of operation is detected first after the registration of the yarn package number Xm is deleted. Therefore, the yarn package determination device 30 executes the steps ST001-ST002-ST004-ST005-ST006-ST007 described with reference to FIG.

  [When there is an eighth to tenth yarn abnormality detection signal S1]

  As shown in FIG. 9, the number Ym of abnormality detections when the yarn package determination device 30 detects the eighth to tenth yarn abnormality detection signals S1 from the start of operation is 1-3. That is, the abnormality detection count Ym is different from the determination reference count N. Therefore, the yarn package determination apparatus 30 executes the steps ST001-ST002-ST004-ST008-ST010'-ST007 described with reference to FIGS.

  [When there is an eleventh yarn abnormality detection signal S1]

  As shown in FIG. 9, when the yarn package determination device 30 detects the eleventh yarn abnormality detection signal S1 from the start of operation, the number of abnormality detections Ym is 4, which is the same as the determination reference number N. Further, as shown in “second determination” in the “determination target winding length” column of FIG. 9, the value of the formula Zmn−Zm0, that is, the determination target winding length is equal to or less than the determination reference length L.

  Therefore, the yarn package determination device 30 performs steps ST001-ST002-ST004-ST008-ST010'-ST011 ''-ST012 ''-ST013-ST014-ST015-ST016-ST007 described with reference to FIGS. Execute. Accordingly, the operator replaces the A yarn package 14 determined to be defective with a new B yarn package 14, and then operates the replacement package reset switch SW1 (ST015).

  [When there is a 12th to 16th yarn abnormality detection signal S1]

  The yarn package determination device 30 executes the steps shown when the second to sixth yarn abnormality detection signals S1 are present.

  In this way, even if the yarn package determination device 30 once determines that the yarn package 14 is good, the yarn package determination device 30 continues a series of determination operations by detecting an abnormality. The determination device 30 can cope with the yarn package 14 in which the inner layer portion of the yarn package 14 is defective, and avoids a decrease in the operation rate by extracting.

  [Example 4]

  The creel / warper apparatus 10 according to the fourth embodiment will be described with reference to FIGS. 11 to 12. The creel / warper apparatus 10 according to the fourth embodiment has the same configuration as that of FIG.

  FIG. 11 is a timing chart of the creel / warper apparatus 10. FIG. 12 is a flowchart of the quality determination of the yarn package 14.

  In the present embodiment, the yarn package 14 with the yarn package number Xm is determined to be good or bad during operation, and if it is determined to be defective, a failure display is made. When the operation of the creel / warper device 10 is stopped, the yarn package 14 is replaced with another new yarn package 14 based on the failure indication.

  Specifically, the yarn abnormality detection signal S1 is output and the operation is stopped, and the operator repairs the yarn 16 of the yarn package 14 with the yarn package number Xm and resumes the operation. When 18 winds up a predetermined determination reference length L, the yarn package determination device 30 performs a determination operation. If the abnormality detection count Ym of the yarn abnormality detection signal S1 is equal to or greater than the determination reference count N while winding the determination reference length L, the yarn package determination device 30 determines that the yarn package 14 with the yarn package number Xm is defective. When the yarn package 14 of the other yarn package number X is stopped due to yarn breakage, or rarely, the yarn package 14 of the yarn package number Xm determined to be defective is replaced.

  As described above, the first yarn abnormality occurring during the period when the winding length Z does not reach the monitoring start length Ls is invalidated and is not stored in the storage device 32 at all. Upon detection of the second yarn abnormality from the start of operation, the yarn package number Xm is registered (ST106), and the winding length Z of the winding beam 18 is input from the operation control device 34 to the yarn package determination device 30 and wound. It is read out as a taking length Zm0 (ST107). The yarn package determination device 30 calculates Zm0 + L obtained by adding the determination reference length L to the winding length Zm0 and stores it in the storage device 32 (ST108). Next, after the yarn 16 is repaired, the operation is resumed (ST104). As in the other embodiments, when the yarn package number Xm is registered, the occurrence of yarn abnormality is not written in the storage device 32, so the yarn abnormality detection count Ym is zero.

  Upon detection of the third yarn abnormality from the start of operation, the step moves from ST102 to ST109, the yarn abnormality detection frequency Ym is incremented by 1 to Ym = 1 (ST109), and the winding length Z of the winding beam 18 is reached. Is input from the operation control device 34 to the yarn package determination device 30 and read as the winding length Zm1 (ST110), and Zm1 + L obtained by adding the determination reference length L is calculated and stored in the storage device 32. (ST111). Next, after the yarn 16 is repaired, the operation is resumed (ST112).

  In the yarn package 14 of the yarn package number Xm, the yarn package determination device 30 detects the winding length Z input from the operation control device 34 and Zmc + L stored in the storage device 32 in addition to detecting yarn abnormality. Compare regularly. After restarting the operation in step ST112, the process proceeds to step ST113, and if the yarn abnormality is detected by this comparison, the process proceeds from step ST113 to step 101. If the yarn abnormality is not detected, the process proceeds from step ST113. The process proceeds to step ST114. In step ST114, the yarn package determination device 30 compares the winding length Z input from the operation control device 34 with Zmc + L stored in the storage device 32, and the winding length Z has reached Zmc + L. If not, the process returns to step ST113. If the winding length Z has reached Zmc + L, the process proceeds to step ST115. Here, the number C of Zmc given is 0, 1, 2, 3, 4,. Zmc is Zm0 when n = 0 in Zmn, Zm1 when n = 1, Zm2 when n = 2, Zm3 when n = 3, Zm4 when n = 4, ..., that is, the winding length of the winding beam 18 when the yarn abnormality detection count Ym is 0, 1, 2, 3, 4, ... in the yarn package 14 of the yarn package number Xm, respectively. Z.

  As shown in FIG. 11, before the winding length Z of the winding beam 18 reaches Zm0 + L, the next yarn breakage, that is, the fourth yarn abnormality from the start of operation, occurs. Transition.

  In the occurrence of the fourth yarn abnormality from the start of operation, after the operation is restarted in step ST112, before the next yarn breakage occurs, that is, before the fifth yarn abnormality occurs from the start of operation, the winding beam 18 The winding length Z has reached Zm0 + L. Therefore, in step ST113, if the yarn abnormality is not detected by the above-described regular comparison, the step that has shifted from step ST113 to step ST114 is shifted to step ST115.

  In step ST115, Ym-C is calculated. Since Ym = 2 and C = 0, Ym-C = 2-0 = 2. Next, in step ST116, Ym-C is compared with the determination reference number N (N = 4 in the embodiment), and Ym-C = 2 is smaller than the determination reference number N. Therefore, the yarn package 14 of the yarn package number Xm Is determined to be good, and then the process proceeds to step ST120.

  In step ST120, 1 is added to the number of grants C from 0 to 1, and then the process returns to step ST113.

In step ST113, the yarn package determination device 30 periodically compares the winding length Z from the operation control device 34 with Zm1 + L stored in the storage device 32. As shown in FIG. 11, before the winding length Z reaches Zm1 + L, since the fifth yarn abnormality has occurred since the start of operation, the process proceeds to step ST101.

  Due to the occurrence of the fifth yarn abnormality from the start of operation, the step proceeds to ST101-ST102-ST105-ST109-ST110-ST111-ST112, the operation is resumed in step ST112, and then proceeds to step ST113. As shown in FIG. 11, the winding length Z reaches Zm1 + L before the sixth yarn abnormality occurs from the start of operation. Therefore, in step ST113, if the yarn abnormality is not detected by the above-described regular comparison, the step that has shifted from step ST113 to step ST114 is shifted to step ST115.

In step ST115, Ym-C is calculated, and since Ym = 3 and C = 1, Ym-C = 3-1 = 2. Next, in step ST116, Ym-C is compared with the determination reference number N, and since Ym-C = 2 is smaller than the determination reference number N (= 4), it is determined that the yarn package 14 with the yarn package number Xm is good. Then, the process proceeds to step ST120.

  In step ST120, 1 is added to the number of grants C to 2, and then the process returns to step ST113.

In step ST113, the yarn package determination device 30 periodically compares the winding length Z from the operation control device 34 with Zm2 + L stored in the storage device 32. As shown in FIG. 11, before the winding length Z reaches Zm2 + L, since the seventh yarn abnormality has occurred since the start of operation, the process proceeds to step ST101.

  Due to the occurrence of the seventh yarn abnormality from the start of operation, the step proceeds to ST101-ST102-ST105-ST109-ST110-ST111-ST112, the operation is resumed in step ST112, and then proceeds to step ST113. In step ST113, the yarn package determination device 30 periodically compares the winding length Z from the operation control device 34 with Zm2 + L stored in the storage device 32. As shown in FIG. 11, the winding length Z reaches Zm2 + L before the eighth yarn abnormality occurs from the start of operation. Therefore, in step ST113, if the yarn abnormality is not detected by the above-described regular comparison, the step that has shifted from step ST113 to step ST114 is shifted to step ST115.

In step ST115, Ym-C is calculated and Ym = 4 and C = 2, so that Ym-C = 4-2 = 2. In step ST116, since Ym-C is smaller than the determination reference number N (= 4), the yarn package 14 is determined to be good, and the process proceeds to step ST120.

  In step ST120, the number of grants C is incremented by 1 from 2 to 3, and then returns to step ST113.

In step ST113, the yarn package determination device 30 periodically compares the winding length Z from the operation control device 34 with Zm3 + L stored in the storage device 32. As shown in FIG. 11, before the winding length Z reaches Zm3 + L, the eighth yarn abnormality has occurred from the start of operation, so the process proceeds to step ST101.

  Due to the occurrence of the eighth yarn abnormality from the start of operation, the step proceeds to ST101-ST102-ST105-ST109-ST110-ST111-ST112, the operation is resumed in step ST112, and then proceeds to step ST113. In step ST113, as shown in FIG. 11, since the ninth yarn abnormality has occurred from the start of operation before the winding length Z reaches Zm3 + L, the process proceeds to step ST114.

  Due to the occurrence of the ninth yarn abnormality from the start of operation, the step proceeds to ST101-ST102-ST105-ST109-ST110-ST111-ST112, the operation is resumed in step ST112, and then proceeds to step ST113. In step ST113, the yarn package determination device 30 periodically compares the winding length Z from the operation control device 34 with Zm3 + L stored in the storage device 32. As shown in FIG. 11, the winding length Z reaches Zm3 + L before the next yarn abnormality occurs. Therefore, in step ST113, if the yarn abnormality is not detected by the above-described regular comparison, the step that has shifted from step ST113 to step ST114 is shifted to step ST115.

In step ST115, Ym-C is calculated, and Ym = 7 and C = 3. Therefore, Ym-C = 7-3 = 4. Next, in step ST116, Ym-C is compared with the determination reference number N (= 4), and Ym-C = 2 is the same as the determination reference number N. Therefore, the yarn package 14 with the yarn package number Xm is determined to be defective. Then, the process proceeds to step ST117. In step ST117, the yarn package determination device 30 outputs a display signal S22 and causes the indicators 22 and 48 to display a defect.

  When the operation is stopped due to yarn breakage or the like of the yarn package 14 of the other yarn package number X, the operator removes the A yarn package 14 and attaches another B yarn package 14 (ST118).

  Next, the operator operates the replacement package reset switch SW1, deletes the registration of the yarn package number Xm, and cancels the failure display by the indicators 22 and 48 (ST119).

  In any of the above-described embodiments, the yarn package 14 with the yarn package number X for which yarn abnormality detection is performed only once is not judged as good or bad, so the operation ends without being judged as defective. Until maintained.

  In any of the above-described embodiments, the yarn abnormality detection and a series of pass / fail judgment operations of the yarn package 14 based thereon are continued until the operation is completed. However, when the winding length from the start of operation becomes a predetermined length or more, a series of pass / fail judgment operations of the yarn package 14 may not be performed, and a predetermined operation is performed from the start of operation using a timer. After a lapse of time, a series of quality determination operations for the yarn package 14 may not be executed. The defective yarn package 14 is largely exchanged until the winding length from the start of operation reaches a predetermined length or until a predetermined operation time elapses from the start of operation, and the number of the defective yarn packages 14 decreases. This is because the defective yarn package 14 having a reduced yarn amount is not frequently lowered even if it is not replaced because the number of times is small even if yarn abnormality is detected.

  The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.
