Background technology
[0002]
　Patent Document 1 includes an automatic winder including a plurality of winding units for winding a yarn supplied from a yarn feeding section into a winding pipe to form a package, and a ball-lifting carriage for lifting the formed package. It is disclosed. The take-up unit is a yarn quality measuring device (clearer) that monitors the yarn running from the yarn feeder toward the take-up pipe and detects yarn defects, and cuts the yarn when a yarn defect is detected. It has a cutter and a thread splicing device for splicing the cut thread. For example, the clearer monitors the thickness of the thread, and if it determines that a portion that is too thick or too thin with respect to the target thickness is a thread defect, the clearer causes the cutter to cut the thread. The yarn cut by the cutter and divided into the yarn feeder side and the take-up pipe side in the yarn running direction can be taken up by the take-up pipe again by being spliced ​​by the yarn splicing device. .. In this way, the take-up unit winds the yarn on the bobbin while removing the yarn defects. The ball-lifting carriage travels between a plurality of winding units and performs a ball-lifting operation of removing a fully wound package from the winding unit.
[0003]
　More specifically, in the clearer, for example, as disclosed in Patent Document 2, an upper limit limit and a lower limit limit for determining whether or not a thread defect has occurred in a running thread are set. If the difference between the running thread and the target thickness exceeds the upper and lower limits, the clearer determines that an unacceptable thread defect has occurred and causes the cutter to cut the thread. If the above difference is within the limit, the clearer will continue to run without cutting the thread. Further, the clearer determines that the portion of the thread in which the above difference is within the limit and is close to the limit is an allowable thread defect, and stores the information.

Outline of the invention
Problems to be solved by the invention
[0005]
　Of the threads, the portion determined to be an unacceptable thread defect is cut and removed, but the portion determined to be an acceptable thread defect is not cut and is wound around the take-up pipe as it is. Will be included in the package. It is preferable to treat a package containing an allowable amount of thread defects in a predetermined amount or more as a semi-good product having a lower thread quality than a non-defective product having few allowable thread defects, separately from a non-defective product. However, a ball-fried trolley as described in Patent Document 1 generally lifts balls without distinguishing between a good product package and a semi-good product package. Therefore, there is a risk that non-defective products and semi-non-defective products will be shipped together.
[0006]
　An object of the present invention is to make it possible to sort a good product package and a semi-good product package.
Means to solve problems
[0007]
　The textile machine of the first invention is a textile machine including a winding unit that executes a yarn winding process of winding a yarn supplied from a yarn feeding unit into a winding pipe to form a package, and the winding unit. Monitors the running yarn, detects non-tolerant defects that need to be removed and tolerant defects that do not need to be removed, and cuts the yarn when the non-tolerant defects are detected. Based on the data of the allowable defects, it is determined whether the package is a non-defective product in which the total amount of the allowable defects is equal to or less than a predetermined reference value or a semi-good product in which the total amount of the allowable defects exceeds the reference value. It has a determination unit and a unit control unit, and when the determination unit determines that the package is a semi-good product, the unit control unit operates differently from the case where the package is a non-defective product. It is characterized in that it is performed by the winding unit.
[0008]
　In the present invention, when the yarn quality measuring device determines that the package is a semi-good product, the winding unit operates differently from normal (when the package is a good product), thereby indicating that the package is not a good product. Can be noticed. Therefore, it is possible to sort a good product package and a semi-good product package.
[0009]
　The textile machine of the second invention is characterized in that, in the first invention, the yarn quality measuring device has the determination unit.
[0010]
　If a thread quality measuring device for detecting allowable defects and a judging unit for judging the quality of the package are separately provided, problems such as an increase in data communication volume and an increase in cost may occur. In the present invention, since the thread quality measuring device has a determination unit, the occurrence of these problems can be suppressed.
[0011]
　In the textile machine of the third invention, in the first or second invention, the winding unit has a notification unit for notifying information, and the unit control unit says that the package is the semi-good product. When it is determined by the determination unit, it is characterized in that the notification unit is notified of information indicating that the package is a semi-good product.
[0012]
　In the present invention, since the notification unit notifies that the package is a semi-good product, it is possible to promptly notify the operator that the package is a semi-good product, and it is possible to prompt the operator to take prompt action.
[0013]
　In the textile machine of the fourth invention, in any one of the first to third inventions, the determination unit is detected by the yarn quality measuring device while the package is being formed by the winding unit. It is characterized in that the amount of the allowable defects is sequentially added, and when the total amount of the allowable defects contained in the package exceeds the reference value, the package is judged to be a semi-good product. ..
[0014]
　In the present invention, when it is determined that the package being formed is a semi-good product, the winding unit can be made to perform an operation different from the normal operation (when the package is a good product). Therefore, semi-good products can be sorted early.
[0015]
　In the fourth invention, the textile machine of the fifth invention is the winding when the unit control unit determines that the package is a semi-good product by the determination unit during the formation of the package. It is characterized in that the thread winding process by the taking unit is interrupted.
[0016]
　For example, if the package is judged to be a semi-good product at the beginning of the thread winding process by the winding unit, if the thread winding process is continued as it is, the amount of allowable defects is considerably large among the semi-good products, and the quality is inferior. Package may be formed. In the present invention, since the thread winding process can be interrupted when the package is determined to be a semi-good product, the poor quality package can be removed even during the formation of the package.
[0017]
　In the textile machine of the sixth invention, in the fourth invention, even if the unit control unit determines that the package is a semi-good product during the formation of the package, the package It is characterized in that the winding unit continues to form the package until the winding is full.
[0018]
　In the present invention, even if it is found that the package is a semi-good product during the formation of the package, the package can be fully wound faster than the case where the thread winding process is interrupted by continuing the formation of the package. It is possible to suppress a decrease in production efficiency.
[0019]
　In any one of the first to sixth inventions, the textile machine of the seventh invention includes a ball lifting device for lifting the package, and the unit control unit determines that the package is a good product. It is characterized in that a ball lifting request signal requesting ball lifting by the ball lifting device is output, and when the determination unit determines that the package is a semi-good product, the ball lifting request signal is not output. Is to be.
[0020]
　In the present invention, since the semi-good product can be prevented from being lifted by the ball lifting device, the operator removes the semi-good product from the winding unit and handles it separately from the non-defective product, thereby ensuring a mixture of the non-good product and the semi-good product. Can be prevented.
[0021]
　In the seventh invention, the textile machine of the eighth invention identifies the semi-good product as the non-defective product when the unit control unit determines that the package is the semi-good product by the determination unit. It is characterized in that it outputs a signal requesting the ball lifting device to give the identification information that enables it.
[0022]
　In the present invention, since the ball-lifting device can be provided with identification information for making the semi-good product distinguishable from the non-defective product, sorting can be performed even when the non-defective product and the semi-good product are mixed. In addition, it is possible to save the trouble of assigning the identification information by the operator.
[0023]
　In any one of the first to sixth inventions, the textile machine of the ninth invention includes a ball lifting device for lifting the package, and the unit control unit uses the determination unit to determine that the package is a semi-good product. If it is determined that the product is, the ball lifting device is provided with identification information that makes the semi-good product distinguishable from the non-good product before outputting a signal requesting the ball lifting by the ball lifting device. It is characterized in that it outputs a requested signal to be performed.

In addition, it is possible to save the trouble of assigning the identification information by the operator. Further, as compared with the case where the ball lifting request signal is not output, it is possible to save the trouble of removing the semi-good package by the operator.
[0025]
　In any one of the first to sixth inventions, the textile machine of the tenth invention includes a ball lifting device for lifting the package, and the winding unit requires the ball lifting device to lift balls. When the unit control unit has an operation unit in which the ball lifting request operation for outputting the ball lifting request signal is performed by the operator, the unit control unit determines that the package is a semi-good product by the determination unit. It is characterized in that the ball lifting request signal is output only when the ball lifting request operation is performed by the operator.
[0026]
　In the present invention, the semi-good product is not lifted until the operator performs the ball lifting request operation. Therefore, before performing the ball lifting request operation, the operator can take measures to make the good product and the semi-good product distinguishable. Therefore, even when good products and semi-good products are mixed by deep-fried semi-good products, sorting can be performed. In addition, by lifting the balls with the ball lifting device, it is possible to save the operator the trouble of removing the semi-good package.
[0027]

The unit control unit is characterized in that when the determination unit determines that the package is a semi-good product, the stopper is positioned at the blocking position.
[0028]
　In the present invention, the package can be stopped on the individual aisle by a stopper before the formed package facing the conveyor is mixed with other packages on the conveyor or at the destination. Therefore, before a plurality of packages are mixed on the conveyor or at the transportation destination, the operator can add information for identifying the semi-good product to the non-defective product package. It is also possible for the operator to remove the stopped semi-good products.
[0029]
　In the textile machine of the twelfth invention, in any one of the first to eleventh inventions, the determination unit determines the occurrence of the non-permissible defect and the occurrence of the permissible defect by the yarn quality device. It is characterized in that it is performed based on the thickness of the monitored thread.
[0030]
　In general, if there is a large variation in the thread thickness in the package, uneven dyeing is likely to occur. Therefore, it is effective to monitor the thread thickness in forming the package. In the present invention, the occurrence of non-permissible defects and the occurrence of permissible defects are determined based on the thickness of the thread. Therefore, it is possible to accurately detect the thread defect that needs to be removed and accurately judge the quality of the formed package.

(Details of Yarn Clearer)
　Next, the details of the yarn clearer 34 will be described with reference to FIGS. 5 and 6. FIG. 5A is a diagram showing a thread Y containing an unacceptable defect Yb that needs to be removed. FIG. 5B is a diagram showing a thread Y containing an allowable defect Yc that does not need to be removed. FIG. 6 is a graph showing the distribution of thread thickness in a certain package P.
[0050]
　The clearer main body 34a (thread quality measuring unit of the present invention) of the yarn clearer 34 is, for example, an optical sensor (not shown) and a clearer control unit 37 (the present invention) that acquires thread thickness information based on the detection result by the sensor. Judgment unit) and. The clearer control unit 37 is built in the clearer main body 34a, and includes a CPU, a ROM, a RAM, and the like. The clearer control unit 37 detects the difference (deviation) between the thickness of the traveling thread Y and the target thread thickness. When the deviation is within the range of the upper and lower limits of the predetermined upper and lower limits, the clearer control unit 37 passes the thread Y as it is, and when the deviation is out of the limit range, it needs to be removed. It is determined that an unacceptable defect has occurred, and the cutter 34b (cut portion of the present invention) cuts the thread Y. The non-permissible defect is removed by being sucked by the needle thread catching guide member 36 when the cut thread Y is thread-joined by the thread splicing device 33. The clearer main body 34a and the cutter 34b may be integrally installed on the frame (not shown), or may be individually provided.
[0051]
　First, the defect of the thread Y will be briefly described with reference to FIG. As shown in FIG. 5A, the portion of the running thread Y having a thickness Ta substantially close to the target thickness is defined as a normal thread Ya. When the yarn clearer 34 detects a portion of the thread Y having a thickness Tb considerably larger than the target thickness, the clearer control unit 37 determines that an unacceptable defect Yb has occurred, and applies the thread Y to the cutter 34b. To disconnect. On the other hand, as shown in FIG. 5B, when a portion having a thickness Tc slightly thicker than the target thickness is detected by the yarn clearer 34, if the thickness Tc does not exceed the upper limit, the clearer control unit 37 Determines that the portion is normal or has an allowable defect Yc, and allows the portion to pass downstream in the thread traveling direction. In this way, the clearer control unit 37 determines the occurrence of the non-permissible defect Yb and the occurrence of the permissible defect Yc based on the thickness of the thread Y monitored by the yarn clearer 34.
[0052]
　The clearer control unit 37 stores reference values ​​for identifying normal threads Ya, non-permissible defects Yb, and permissible defects Yc. Hereinafter, a specific description will be made with reference to FIG. In the graph shown in FIG. 6, the horizontal axis represents the length of the monitored thread Y, and the vertical axis represents the thread thickness (specifically, the deviation (%) from the target thread thickness). Represents. On the vertical axis, a value of 0% indicates a target thread thickness. For example, a value of 100% indicates a thread thickness that is 100% thicker than the target thread thickness (that is, twice the target thread thickness). Further, for example, a value of −30% indicates a thread thickness that is 30% thinner than the target thread thickness.
[0053]
　In the graph of FIG. 6, the filled area 101 shows the normal distribution of threads Ya. The polygonal line 102 drawn above the paper surface of the region 101 indicates the upper limit of thread cutting. The polygonal line 103 drawn below the paper surface of the region 101 indicates the lower limit of thread cutting. The upper and lower limits depend on the length of the monitored thread Y. If a short thread defect is detected, a limit is set to allow even a slightly larger deviation. On the contrary, when a long thread defect is detected, it is determined whether or not to remove the long thread defect based on a limit stricter than the limit provided corresponding to the short thread defect. For example, when a thread defect having a thread thickness deviation of 100 to 150% is detected, it is permissible if the length is a little over 1 cm, but it is not permissible if the length is longer than that. The upper and lower limits are not necessarily fixed, and may vary depending on the average thickness of the thread Y and the like during the formation of the package P (detailed description will be omitted here). For details regarding the detection of thread defect information by the yarn clearer 34, refer to, for example, Japanese Patent No. 5680653. Further, Japanese Patent Application Laid-Open No. 2013-227155 also discloses a method of processing and displaying the thickness and length information of the detected thread defect.
[0054]
　Of the thread Y, a portion having a defect exceeding the upper limit limit indicated by the polygonal line 102 or below the lower limit limit indicated by the polygonal line 103 is cut and removed as an unacceptable defect Yb as described above. Therefore, the unacceptable defect Yb does not remain in the package P. The square mark 201 in the graph indicates the unacceptable defect Yb. For example, the mark 201 marked at a position of 3 cm on the horizontal axis and 100% on the vertical axis indicates that a thread defect 100% thicker than the target thread thickness has occurred over a length of 3 cm. In this way, the clearer control unit 37 stores information on the non-permissible defect Yb.
[0055]
　Information on the permissible defect Yc is stored in the region 104 between the region 101 and the polygonal line 102 and the region 105 between the region 101 and the polygonal line 103. The triangular mark 202 in the graph indicates the permissible defect Yc. The permissible defect Yc is not removed, but is stored in the clearer control unit 37 as a defect remaining in the package P.
[0056]
　Further, the plurality of frames 106 formed by the broken lines represent the classification of defects. That is, the farther the deviation of the thread thickness is from 0, the higher the level as a defect. For example, the defect level of the allowable defect Yc related to the mark 203 in the frame 107 first from the left side of the paper and the third from the upper side of the paper is related to the mark 204 in the frame 108 first from the left side of the paper and the fourth from the upper side of the paper. Higher than the defect level of the allowable defect Yc.
[0057]
　Here, it is preferable to treat the package P containing the allowable defect Yc in a predetermined amount or more as a semi-good product having a lower thread quality than a good product having a small allowable defect Yc, separately from the good product. However, if the ball lifting device 3 lifts the balls without distinguishing between the non-defective package P and the semi-good package P, there is a risk that the non-defective and semi-good products will be shipped together. Therefore, in the automatic winder 1 of the present embodiment, the clearer control unit 37 and the unit control unit 60 perform the following processing in order to make it possible to sort good products and semi-good products.
[0058]
(Processing by Clearer Control Unit)
　First, the processing by the clearer control unit 37 will be described with reference to FIGS. 6 and 7. FIG. 7 is a graph showing the degree of progress of the thread winding process (increase in the thread winding length) in the package P and the accompanying increase in the total amount of allowable defects Yc.
[0059]
　The clearer control unit 37 determines whether or not the package P is a semi-good product as follows. The clearer control unit 37 accumulates data on thread defects as shown in FIG. 6 while the package P is being formed by the take-up unit 2. When the allowable defect Yc is detected during the formation of the package P, the clearer control unit 37 sequentially adds the amount of the allowable defect Yc. The horizontal axis of the graph shown in FIG. 7 represents the thread winding length of the package P being formed. The vertical axis represents the total amount of allowable defects Yc remaining in the package P (total amount of allowable defects). FIG. 7 shows the transition of the total amount of allowable defects in the two different packages P (solid line and broken line).
[0060]
　As the formation of the package P progresses and the thread winding length becomes longer, the total amount of allowable defects increases each time the allowable defect Yc is detected. Then, when the total amount of allowable defects exceeds a predetermined reference value (see the two-dot chain line in the graph of FIG. 7) during the formation of the package P, it is determined that the package P is a semi-good product. If the total amount of allowable defects exceeds the reference value during the formation of the package P (see the solid line in the graph of FIG. 7), the clearer control unit 37 determines that the package P is a semi-good product at that time, and the package P Is transmitted to the unit control unit 60 with a determination signal indicating that is a semi-good product. On the other hand, if the total amount of allowable defects is below the reference value until the timing of reaching full winding (see the broken line in the graph of FIG. 7), this package P is a good product. That is, if the clearer control unit 37 has not determined that the package P is a semi-good product at the time when the full volume is reached or immediately before the full volume is reached, the package P is a good product. In this case, the determination signal is not transmitted from the clearer control unit 37.
[0061]
　There are several conceivable specific methods for adding the amount of allowable defect Yc by the clearer control unit 37. For example, the number of allowable defects Yc may be simply added when they occur, and when the total number of allowable defects Yc exceeds the reference number, it may be determined that the package P being formed is a semi-good product. ..
[0062]
　Alternatively, each allowable defect Yc is weighted according to the classes classified by the plurality of frames 106 as shown in FIG. 6, the number of defects is added as defect points, and when a predetermined reference point is exceeded. It may be judged as a semi-good product. For example, the above-mentioned frame 107 is closer to the upper limit polygonal line 102 than the frame 108. That is, the defect level of the allowable defect Yc related to the mark 203 in the frame 107 is higher than the defect level of the allowable defect Yc related to the mark 204 in the frame 108. Therefore, for example, the defect amount of the allowable defect Yc related to the mark 203 may be treated as being larger than the defect amount of the allowable defect Yc related to the mark 204, and a large number of defect points may be added.
[0063]
　Alternatively, as shown in Mark 203 and Mark 204, the length and thickness of each allowable defect Yc can be known, and the amount of allowable defect Yc is calculated based on the length (for example, length × thickness). Is calculated as the amount of defects), and may be added sequentially.
[0064]
(Processing by Unit Control Unit)
　Next, processing by the unit control unit 60 when the clearer control unit 37 determines whether or not the package P is a semi-good product will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart showing an example of processing by the unit control unit 60, which is related to the determination by the clearer control unit 37. FIG. 9A is a diagram showing a display by the display unit 50 when the take-up unit 2 is in normal operation (when the package P is being formed). FIG. 9B is a diagram showing a display by the display unit 50 when the ball lifting device 3 is requested to lift balls when the fully wound package P is a good product. FIG. 9C is a diagram showing display by the display unit 50 when the package P is determined to be a semi-non-defective product.
[0065]
　As an initial state, the take-up unit 2 starts the winding operation (thread take-up process) of the thread on the take-up bobbin Bm, and the package P is formed. When the thread winding process by the winding unit 2 is normally performed, nothing is displayed on the display unit 50 as shown in FIG. 9A. If an unacceptable defect Yb is detected by the yarn clearer 34 during the formation of the package P, the thread is cut and spliced. When the allowable defect Yc is detected by the yarn clearer 34, the amount of the allowable defect Yc is sequentially added by the clearer control unit 37 as described above.
[0066]
　The unit control unit 60 determines whether or not a determination signal indicating that the package P is a semi-good product has been received from the clearer control unit 37 during the formation of the package P (S101). When the determination signal is not received, the unit control unit 60 determines whether or not the package P has reached full winding (S102). If the package P has not reached full volume yet, the process returns to S101 to continue the formation of the package P. If the package P will soon reach full volume without receiving the determination signal from the clearer control unit 37, the package P is a good product. In this case, the unit control unit 60 outputs a signal (ball lifting request signal) requesting ball lifting by the ball lifting device 3 via, for example, the machine stand control device 4 (S103). When the ball lifting request signal is being output, the unit control unit 60 displays information on the display unit 50 indicating that the winding unit 2 is performing the ball lifting request, as shown in FIG. 9B. Display (specifically, the lamps 51a and 51b are lit in blue).
[0067]
　During the formation of the package P, when the clearer control unit 37 determines that the package P is a semi-good product and a determination signal is transmitted from the clearer control unit 37 to the unit control unit 60, the unit control unit 60 is described as follows. Is processed. That is, the unit control unit 60 controls the winding unit 2 to interrupt the thread winding process, and causes the display unit 50 to display information indicating that a semi-non-defective product has been generated (S104). As a specific display method, for example, as shown in FIG. 9C, the lamps 51a, 51b, and 51d are lit or blinked in red, and characters are displayed on the character display unit 52. At this stage, the process when the package P is determined to be a semi-non-defective product is temporarily terminated. After that, the operator may manually remove the semi-good package P. Alternatively, the operator may press the manual button 53 on the display unit 50 to restart the thread winding process, and manually remove the package P after the package P is fully wound. When the unit control unit 60 receives the determination signal indicating that the package P is a semi-good product from the clearer control unit 37, the unit control unit 60 does not output the ball lifting request signal. This prevents the semi-good products from being deep-fried. In this way, when the unit control unit 60 determines that the package P is a semi-good product, the unit control unit 60 causes the winding unit 2 to perform an operation different from that when the package P is a non-defective product.
[0068]
　As described above, when the yarn clearer 34 determines that the package P is a semi-good product, the take-up unit 2 is normally (the package P is By performing an operation different from (in the case of a non-defective product), the operator can be made aware that the package P is not a non-defective product. Therefore, the non-defective package P and the semi-non-defective package P can be sorted.
[0069]
　Further, since the yarn clearer 34 has the clearer control unit 37, the amount of data communication is increased as compared with the case where the judgment device for determining that the package P is a semi-good product and the yarn clearer 34 are separately provided. It is possible to suppress the occurrence of problems such as increased costs.
[0070]
　Further, since the display unit 50 notifies that the package P is a semi-good product, it is possible to promptly notify the operator that the package P is a semi-good product, and it is possible to encourage the operator to take prompt action.
[0071]
　Further, when the package P in the process of formation is determined to be a semi-good product, the winding unit 2 can be made to perform an operation different from the usual operation. Therefore, semi-good products can be sorted early.
[0072]
　Further, since the thread winding process can be interrupted when the package P is determined to be a semi-good product, the poor quality package P can be removed even during the formation of the package.
[0073]
　Further, since the semi-good product can be prevented from being lifted by the ball lifting device 3, the operator removes the semi-good product from the winding unit 2 and handles it separately from the non-defective product, thereby ensuring the mixture of the non-good product and the semi-good product. Can be prevented.
[0074]
　Further, the determination of the occurrence of the non-permissible defect Yb and the determination of the occurrence of the permissible defect Yc are performed based on the thickness of the thread Y. Therefore, it is possible to accurately detect the thread defect that needs to be removed and accurately judge the quality of the formed package P.
[0075]
　Next, a modified example in which the embodiment is modified will be described. However, those having the same configuration as that of the above embodiment are designated by the same reference numerals and the description thereof will be omitted as appropriate.
[0076]
(1) In the above embodiment, the unit control unit 60 interrupts the thread winding process when the determination signal indicating that the package P is a semi-good product is received from the clearer control unit 37. Is not limited. That is, as shown in FIG. 10, even when the determination signal is received from the clearer control unit 37, the unit control unit 60 may continue the thread winding process as it is until the package P is fully wound (S105). Then, when the package P is full, the display unit 50 may notify the operator (S106). As a result, even if it is found that the package P is a semi-good product during the formation of the package P, the package P is fully wound earlier than the case where the thread winding process is interrupted by continuing the formation of the package P. It is possible to suppress a decrease in production efficiency. That is, when the unit control unit 60 determines that the package P is a semi-good product, the unit control unit 60 winds up an operation different from that when the package P is a good product at the time when the package P is full or after the package P is full. You may let unit 2 do it. Even in this modification, the unit control unit 60 does not output the ball lifting request signal, so that it is possible to prevent a mixture of good products and semi-good products. The unit control unit 60 may notify the operator by the display unit 50 before the semi-good package P is fully wound (for example, when a determination signal is received).
[0077]
(2) In the above-described embodiment, the ball lifting device 3 does not lift the semi-good package P, but the present invention is not limited to this. For example, when the manual button 53 (operation unit of the present invention) of the display unit 50 of the winding unit 2 is pressed while the semi-good package P is held in a winding unit 2, a ball lifting request is made. The unit control unit 60 may determine that the operation has been performed and output a ball lifting request signal. In such a configuration, the semi-good product is not fried until the operator performs the fried food request operation. Therefore, the operator stamps or affixes a sticker on the package P of the semi-good product in advance to make the semi-good product identifiable as a non-defective product, and then presses the manual button 53 to separate the non-defective product from the semi-good product. Even if they are mixed, they can be sorted. Further, by lifting the balls with the ball lifting device 3, it is possible to save the operator the trouble of removing the semi-good package P. The operation may be performed by an operation unit other than the manual button 53.
[0078]
(3) In the modified example of (2) above, the operator performs measures such as stamping the package P of the semi-good product, but the ball lifting device 3 stamps the surface of the package P. (Not shown) may be provided. On that basis, the unit control unit 60 may perform the following processing. That is, as shown in FIG. 11, when the clearer control unit 37 determines that the package P is a semi-good product, the unit control unit 60 continues the thread winding process until the winding unit 2 reaches full winding ( S106). After that, the unit control unit 60 outputs a signal requesting the embossing device 3 to stamp (that is, give identification information) to the surface of the semi-good product package P via the machine base control device 4 (S107). .. As a result, since the ball lifting device 3 can be stamped to make the semi-good product distinguishable from the non-defective product, it is possible to sort even when the non-defective product and the semi-good product are mixed. In addition, it is possible to save the trouble of stamping by the operator.
[0079]
　The identification information is not limited to the stamp, and may be anything. For example, the ball lifting device 3 may be configured to attach a sticker (not shown) to the semi-good package P. Alternatively, for example, an IC tag (not shown) for storing individual information is provided on the winding bobbin Bm, and the package P is a semi-good product on the IC tag of the winding bobbin Bm on which the semi-good product package P is formed. The bobbin 3 may be configured so that information indicating the existence can be written.
[0080]
(4) When the ball lifting device 3 has a configuration capable of stamping the surface of the package P as in the modified example of (3) above, the unit control unit 60 has the following structure. Processing may be performed. That is, as shown in FIG. 12, when the clearer control unit 37 determines that the package P is a semi-good product, the unit control unit 60 outputs a signal requesting the package P of the semi-good product to be given identification information. After that (S107), a ball lifting request signal may be further output (S103). As a result, even when a good product and a semi-good product are mixed, the semi-good product can be identified as a good product, so that the products can be sorted. In addition, it is possible to save the trouble of assigning the identification information by the operator. Further, as compared with the case where the ball lifting request signal is not output, the trouble of removing the semi-good package P by the operator can be saved. Alternatively, the unit control unit 60 may output the ball lifting request signal before outputting the signal requesting the addition of the identification information to the semi-non-defective package P. In this case, the ball lifting device 3 may be provided with the identification information before the ball is lifted.
[0081]
(5) Alternatively, a non-defective product and a semi-non-defective product may be able to be sorted by the configuration as shown in FIG. FIG. 13A is a plan view of the automatic winder 1b. FIG. 13B is a diagram showing a state when the stopper 73, which will be described later, is in the allowable position. FIG. 13C is a diagram showing a state when the stopper 73 is in the blocking position. The illustration of the ball lifting device 3 is omitted.
[0082]
　As shown in FIG. 13 (a), on the rear side of the automatic winder 1b, a conveyor 71 for transporting the package P lifted from the plurality of winding units 2 (see the arrow in FIG. 13 (a)) is provided. ing. Further, as shown in FIGS. 13 (a) to 13 (c), an individual passage 72 is provided between each take-up unit 2 and the conveyor 71 in the front-rear direction in which the fried package P moves rearward. ing. Further, in the front-rear direction, a gap is formed between the conveyor 71 and the individual passage 72, and the stopper 73 is arranged in the gap. The stopper 73 is, for example, a plate-shaped member, which can be moved in the vertical direction by an air cylinder 74 (see the solid line and the broken line in FIG. 13B). The air cylinder 74 can be driven by the unit control unit 60 of the take-up unit 2 and moves the stopper 73 in the vertical direction. When the stopper 73 is located at the lowest position (see the solid line in FIG. 13B), the fried package P can roll through the individual aisles 72 and reach the conveyor 71 as it is. At this time, the stopper 73 is located at an allowable position that allows the package P to roll. On the other hand, when the stopper 73 protrudes upward (see FIG. 13C), the stopper 73 prevents the package P from rolling. At this time, the stopper 73 is located at a blocking position that prevents the package P from rolling. In this way, the stopper 73 can switch the position between the allowable position and the blocking position.
[0083]
　In the automatic winder 1b having the above configuration, when the package P of a certain take-up unit 2 is a good product (when the determination signal from the clearer control unit 37 is not transmitted to the unit control unit 60), the stopper 73 It is located in an acceptable position (see FIG. 14B). On the other hand, when the clearer control unit 37 determines that the package P is a semi-good product, the unit control unit 60 drives the air cylinder 74 to move the stopper 73 to the blocking position. As a result, even if the semi-good package P is fried, the package P can be stopped on the individual passage 72 by the stopper 73. Therefore, before the plurality of packages P are mixed on the conveyor 71 or at the transportation destination, the operator can add information for identifying the semi-good product to the non-defective product package P. It is also possible for the operator to remove the stopped semi-good products.
[0084]
(6) In the above-described embodiments, whether or not the package P is a semi-good product is determined based on the total amount of allowable defects Yc, but the present invention is not limited to this. For example, the clearer control unit 37 may determine whether or not the package P is a semi-good product based on the total amount of allowable defects Yc, or instead, based on the specific amount of allowable defects Yc. Examples of the amount of the specific permissible defect Yc include the amount of the portion thicker than the target thickness, the amount of the portion thinner than the target thickness, the amount of fluff, and the like. Alternatively, the clearer control unit 37 may determine whether or not the package P is a semi-good product based on the number of thread cuts by the cutter 34b. When the number of times the thread Y is cut by the cutter 34b (that is, the number of detected non-permissible defects Yb) is large, the number of times of thread splicing by the thread splicing device 33 is large, and the number of thread splicing portions in the package P is large. Since such a package P is not of good quality, it may be determined whether or not it is a semi-good product by counting the number of times the thread is cut by the cutter 34b. That is, the amount of allowable defect Yc used by the clearer control unit 37 as a determination criterion is the number of times of thread cutting by the cutter 34b in addition to or instead of the total amount of allowable defect Yc and / or the amount of specific allowable defect Yc. Can be included. The clearer control unit 37 may determine whether or not the package P is a semi-good product based on the number of times the thread is cut by the cutter 34b.
[0085]
(7) In the above-described embodiment, the clearer control unit 37 classifies the package P into two types, a good product and a semi-good product, but the present invention is not limited to this. That is, semi-good products may be further ranked based on the amount of permissible defects Yc. For example, among the semi-good products, those having a relatively small amount of allowable defects Yc may be designated as quasi-first grade products, and those having a relatively large amount of permissible defects Yc may be designated as quasi-second grade products. In this case, in the modified examples of (2) to (5) above, the rank of the semi-good product can be identified by changing the identification information given to the package P of the semi-good product according to the rank. For example, the color and / or shape of the stamp, the color and / or shape of the sticker, the information to be written on the IC tag, and the like may be different depending on the rank of the semi-good product. Alternatively, the semi-good products may be ranked more finely (that is, three or more types).
[0086]
(8) In the above embodiments, the determination signal is transmitted from the clearer control unit 37 to the unit control unit 60 only when the package P is a semi-good product, but the present invention is not limited to this. For example, in a configuration in which the unit control unit 60 and the clearer control unit 37 can communicate in both directions, the unit control unit 60 sends a signal indicating that the package P is about to be fully wound at the timing when the package P is fully wound. You may send it to. Then, if it is not determined that the package P is a semi-good product at this point, a signal indicating that the package P is a non-defective product may be transmitted from the clearer control unit 37 to the unit control unit 60.
[0087]
(9) In the above embodiments, the clearer control unit 37 determines whether or not the package P in the process of formation is a semi-good product, but the present invention is not limited to this. For example, the unit control unit 60 may receive information on the thread defect from the clearer control unit 37 and make the above determination. In this case, the unit control unit 60 corresponds to the determination unit of the present invention.
[0088]
(10) In the above-described embodiment, the display unit 50 notifies the operator, but the present invention is not limited to this. For example, the notification may be performed by using a tower lamp (not shown) provided in the machine base control device 4, or the notification may be performed by sound.
[0089]
(11) The present invention can be applied to other than the automatic winder 1. That is, it can also be applied to a textile machine having a yarn quality measuring device such as a yarn clearer 34 (for example, an air spinning machine and / or an open-end spinning machine).
