Description

  The present invention relates to a textile machine management system for a fine spinning winder. More specifically, the present invention relates to a configuration for assisting a textile machine management system to appropriately perform maintenance of a fine spinning winder.

  Conventionally, the timing of performing maintenance of the textile machine, such as exchanging the belts of the spinning machine traveler and draft section, is left to the experience and judgment of the operator. Therefore, parts are not always replaced at the optimum timing, and the following problems may occur. That is, if the parts are replaced at an early timing, the maintenance cost is increased, and if the parts are replaced at a too late timing, defective threads are produced in large quantities due to the worn parts.

  In this regard, for example, a method of uniformly replacing parts that have passed the manufacturer's recommended use period can be considered. However, in reality, the degree of wear of parts is affected by the device conditions. For this reason, it is not possible to say that the timing is always appropriate even if the parts are replaced based on the recommended period of use recommended by the manufacturer.

  Further, the wound yarn is analyzed, and the timing for replacing the part is determined based on the analysis result. Specifically, the yarn is wound under actual setting conditions, and the wound yarn is manually collected by an operator and analyzed by an analyzer. Then, the life of the part is determined from the analysis result, and the part is replaced after a certain period. However, in this method, there is a problem that the operator needs to collect and analyze the yarn, which is very troublesome.

  On the other hand, a spinning machine management system as disclosed in Patent Document 1 has been proposed. In the configuration of Patent Document 1, a bar code is attached to a tray for conveying a bobbin, and the fine spinning unit in which the bobbin is formed is specified by reading the bar code. With this configuration, it is possible to identify a spinning unit that requires maintenance when a failure occurs. Patent Document 2 discloses a configuration in which a memory chip that is electrically readable and erasable is mounted on a tray (caddy) that conveys a bobbin, and information that can identify the ring spindle on which the bobbin is formed is stored in the memory chip. is doing.

  However, in the configurations of Patent Document 1 and Patent Document 2, it is possible to know which spinning unit has a defect, but no more information can be obtained. That is, although it can be seen that maintenance is necessary for a certain spinning unit, it is necessary to determine which part of the unit should be maintained based on the experience of the operator. Furthermore, even if a unit requiring maintenance can be grasped later, maintenance such as component replacement cannot be performed proactively before inconvenience occurs, and there is a limit in this respect.

  The present invention has been made in view of the above circumstances, and a main object thereof is to provide a textile machine management system that supports efficient maintenance in a fine spinning winder.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to a first aspect of the present invention, a textile machine management system having the following configuration is provided. That is, this textile machine management system is configured as a textile machine management system for a fine spinning winder having a spinning machine, an automatic winder, an automatic bobbin supply device, and a notification unit. The spinning machine includes a plurality of spinning units that generate a yarn from a yarn raw material supplied from a pre-process machine including a plurality of pre-process units and wind the yarn around a bobbin to form an actual bobbin. The automatic winder includes a plurality of winding units that unwind the yarn from the actual bobbin and wind it around a package. The bobbin automatic supply device places the actual bobbin on a tray and supplies the actual bobbin from the spinning machine to each winding unit. In addition, the tray includes a storage unit that stores, as bobbin information, information that can identify the spinning unit that forms the actual bobbin on which the tray is placed. The automatic winder includes a yarn quality monitoring unit that monitors the state of the yarn that is unwound from the actual bobbin by each winding unit and acquires yarn quality information. Each of the winding units includes a reading unit capable of reading the bobbin information from the storage unit of the tray on which the actual bobbin supplied to the winding unit is placed. In addition, when the textile machine management system detects a predetermined feature of the yarn based on the yarn quality information, the textile machine management system can select the feature from the previous process unit or the spinning unit based on the bobbin information. Identify the corresponding unit. In addition, the textile machine management system specifies a corresponding portion that is a portion corresponding to the feature in the corresponding unit based on the yarn quality information, and estimates the state of the corresponding portion. And this textile machine management system can notify the said corresponding | compatible unit, the said corresponding | compatible part, and the state of the said corresponding | compatible part by the said notification part.

  That is, when any abnormality is detected in the yarn, the operator can be notified of the unit that is causing the abnormality and the part that is causing the abnormality in the unit. Can be done appropriately. Further, since the state of the site causing the abnormality is also notified, the operator can appropriately determine at which timing maintenance is to be performed. In addition, the thread condition can be automatically analyzed without taking the time and effort required to manually collect and analyze the thread from the actual bobbin, greatly reducing the burden on the operator. be able to.

  In the textile machine management system, it is preferable that the notification unit notifies a part life of the corresponding part as a state of the corresponding part.

  As a result, the life of the component can be notified to the operator, so that the operator can accurately grasp when the component should be replaced. Therefore, there is no need to replace parts too early and uselessly, and it is not too late to produce parts of poor quality. Excellent in terms of quality.

  In the textile machine management system, when the characteristic of the yarn is abnormal, it is preferable that the notification unit notifies that the corresponding part is in a state requiring maintenance as the state of the corresponding part.

  Thus, when a defective yarn is detected, it is possible to notify the operator that maintenance is necessary and the unit and part that require maintenance. Therefore, the operator can perform maintenance quickly and appropriately, and can recover from the abnormality at an early stage.

  The textile machine management system is preferably configured as follows. That is, the spinning unit is a ring spinning unit provided with a traveler for twisting the yarn. When the textile machine management system detects that the amount of fluff is increasing according to a predetermined characteristic as the characteristic of the yarn, the corresponding part corresponding to the increase in the amount of fluff is specified as the traveler. Based on the fluff amount, the travel time of the parts of the traveler or the necessity of maintenance is estimated and notified by the notification unit.

  That is, when the traveler wears, the amount of yarn fluff increases, so it is necessary to replace the traveler at an appropriate time. In this respect, by configuring as described above, it is possible to estimate the lifetime of the traveler or the necessity of maintenance based on the actual fluff amount of the yarn, so that the traveler can be replaced at an appropriate timing.

  The textile machine management system is preferably configured as follows. That is, at least one of the spinning unit and the pre-process unit includes at least one of a roller and a belt for transporting the yarn or the yarn raw material. Then, when the textile machine management system detects that there is periodic thickness unevenness as a characteristic of the yarn, a roller or a corresponding part corresponding to the thickness unevenness based on the period of the thickness unevenness The belt is specified, and the life of parts of the roller or the belt or the necessity of maintenance is estimated based on the size unevenness and notified by the notification unit.

  In other words, when a failure occurs in a member that rotates and conveys a yarn such as a roller or a belt, periodic thickness unevenness occurs in the yarn. This period of thickness unevenness is specific to the roller or belt in which a defect has occurred. Accordingly, by configuring as described above, it is possible to estimate the life of the roller or the belt or the necessity for maintenance, and therefore it is possible to perform the maintenance of the roller or the belt at an appropriate timing.

  The textile machine management system is preferably configured as follows. That is, each of the fine spinning units is configured such that the yarn raw material is supplied only from a specific preceding process unit among the plurality of preceding process units. Each of the plurality of pre-process units is configured to supply the yarn raw material to a plurality of spinning units. And the textile machine management system is a case where a common yarn characteristic is detected in the actual bobbin formed by a plurality of spinning units, and the plurality of spinning units are removed from a common previous process unit. When the yarn raw material is supplied, the previous process unit is specified as the corresponding unit.

  Thereby, the previous process unit which is a corresponding | compatible unit can be pinpointed reliably.

  The textile machine management system is preferably configured as follows. That is, the yarn quality monitoring unit includes the notification unit. The corresponding part and the state of the corresponding part are specified by the yarn quality monitoring unit.

  Thereby, since it is not necessary to transmit enormous yarn quality information to the outside of the yarn quality monitoring unit, the textile machine management system can be configured simply.

  The textile machine management system can also be configured as follows. That is, the fine spinning winder includes a central control unit having the notification unit. The central control unit identifies the corresponding part and the state of the corresponding part based on the yarn quality information output by the yarn quality monitoring unit.

  Thereby, since it is not necessary for the yarn quality monitoring unit to specify the corresponding part and the state of the corresponding part, the configuration of the yarn quality monitoring unit can be simplified.

  According to the 2nd viewpoint of this invention, the fine spinning winder to which said textile machine management system was applied is provided.

  Since the fine spinning winder can be appropriately maintained by applying the textile machine management system, it is excellent in terms of the quality of the generated package and the maintenance cost.

  Next, an embodiment of the present invention will be described. FIG. 1 is a schematic plan view showing the fine spinning winder 1 according to this embodiment as viewed from above. FIG. 2 is a schematic front view and block diagram of the fine spinning winder 1.

  As shown in FIG. 1, the fine spinning winder 1 includes a tray conveyance path 90 for conveying a tray 50 on which a bobbin 23 is set. The tray conveyance path 90 includes a spinning machine 2, a winder 3, and a bobbin. An automatic supply device 6 is arranged. The tray conveyance path 90 connects between the spinning machine 2 and the winder 3 and has a loop shape, and the bobbin 23 (tray 50) circulates in the tray conveyance path 90. Although only one bobbin 23 and one tray 50 are illustrated in FIG. 1, a plurality of trays 50 are actually conveyed along the tray conveyance path 90.

  In the following description, paying attention to the flow of the tray 50 in the tray conveyance path 90, the upstream side in the conveyance direction of the tray 50 is simply referred to as “upstream side”, and the downstream side in the conveyance direction is simply referred to as “downstream side”. Sometimes.

  First, the configuration of the tray 50 and the bobbin 23 conveyed in the tray conveyance path 90 will be briefly described with reference to FIG. FIG. 3 is an external perspective view of the tray 50 and the bobbin 23 used in the fine spinning winder 1 of the present embodiment.

  As shown on the left side of FIG. 3, the tray 50 includes a base portion 50a formed in a substantially disc shape, and a rod-shaped bobbin insertion portion 50b protruding vertically from the base portion 50a. The tray 50 moves along the tray conveyance path 90 in a state where the protruding direction of the insertion portion 50b faces upward.

  As shown in the center of FIG. 3, the bobbin 23 is formed in an elongated cylindrical shape, and the insertion portion 50b can be inserted therein. As a result, the bobbin 23 can be set on the tray 50 with its longitudinal direction oriented vertically, and can be transported along the tray transport path 90.

  In the following description, the bobbin in which the yarn is wound (the bobbin on the right side in FIG. 3) may be referred to as an “actual bobbin”. In addition, for a bobbin in which the yarn is not wound (the state shown in the center of FIG. 3), the bobbin is referred to as an “empty bobbin” or “empty bobbin” with the intention of particularly emphasizing such a state. There is.

  A textile machine management system that manages information on the bobbin 23 on the tray 50 using an RFID (Radio Frequency IDentification) technology is applied to the fine spinning winder 1 of the present embodiment. More specifically, in each tray 50, an RF tag (recording unit) 60 capable of writing appropriate information is arranged inside the base unit 50a, and information on the bobbin 23 is stored in the RF tag 60 (tray). The status of the bobbin 23 is managed by writing (every 50).

  Next, each configuration of the fine spinning winder 1 will be described along the tray conveyance path 90. The tray conveyance path 90 includes an actual bobbin introduction path 91, an actual bobbin conveyance path 92, a return bobbin conveyance path 93, a bobbin standby loop 94, a bobbin supply path 95, an empty bobbin conveyance path 96, and an empty bobbin return path. 97, a defective bobbin standby path 98, and a replaced bobbin return path 99.

  The actual bobbin introduction path 91 connects the spinning machine 2 and the bobbin automatic supply device 6 so that the tray 50 on which the bobbin 23 is placed can be conveyed from the spinning machine 2 to the bobbin automatic supply device 6. . Hereinafter, the spinning machine 2 will be described.

  As shown in FIG. 2, the spinning machine 2 includes a large number of spinning units 32 arranged in parallel, and a control device 19 that can control these numerous spinning units 32 in an integrated manner. Yes. The spinning machine 2 also has a doffing device (not shown) for doffing the bobbin 23 (actual bobbin) for which the winding of the yarn by the spinning unit 32 has been completed. In addition, when it is necessary to distinguish each spinning unit 32, the alphabet is added to the end of a code | symbol from the left side toward the drawing of the spinning machine 2, and the spinning unit 32a, the spinning unit 32b, ... It shall be written as

  Next, the spinning unit 32 will be described in detail with reference to FIG. As shown in FIG. 4, the fine spinning unit 32 according to the present embodiment is for twisting and spinning the rovings generated by the roving machine in the previous step. Specifically, the spinning machine 2 is configured as a ring spinning machine, and the spinning unit 32 is configured as a ring spinning unit including a draft mechanism 101 and a twisting mechanism 102.

  The draft mechanism 101 includes a plurality of draft rollers, and the draft roller includes a top roller 103 and a bottom roller 104. The top roller 103 includes three draft rollers, a back roller 103a, a middle roller 103b on which an apron belt 105 is mounted, and a front roller 103c. On the other hand, the bottom roller 104 is composed of three draft rollers: a back bottom roller 104a, a middle bottom roller 104b on which an apron belt 105 is mounted, and a front bottom roller 104c. As shown in FIG. 4, the top roller 103 and the bottom roller 104 are disposed so as to face each other across the travel path of the roving yarn, and are configured so that the roving yarn can be nipped with a predetermined pressure. An output shaft of a drive source (not shown) is connected to each of the bottom rollers 104 and can be driven at different speeds. By driving the bottom roller 104, the roving yarn is sent to the twisting mechanism 102 while being drawn.

  The twisting mechanism 102 includes a spindle shaft 111, a ring rail 112, a ring 113, and a traveler 114. The spindle shaft 111 is for rotating the bobbin 23 set on the spindle shaft 111. The ring rail 112 is connected to a driving device (not shown) and is configured to be movable in the longitudinal direction of the bobbin 23. The ring 113 is fixed to the ring rail 112 and has a flange portion for attaching the traveler 114. The traveler 114 is supported by the flange portion of the ring 113 and is configured to be movable in the circumferential direction of the ring 113.

  In order to perform spinning with the spinning unit 32 configured as described above, first, the yarn sent from the draft mechanism 101 (the one in which the coarse yarn has been stretched) is placed between the traveler 114 and the ring 113. The end portion is fixed to the empty bobbin 23 by an appropriate method. When the bobbin 23 is rotated by the spindle shaft 111 in this state, the traveler 114 moves in the circumferential direction so as to be pulled by the yarn wound around the bobbin 23. As a result, the rotation of the traveler 114 is delayed from the rotation of the bobbin 23, and twisting is added to the yarn due to the difference in the number of rotations thus generated. The twisted yarn is sequentially wound around the bobbin 23, and when the yarn is wound around the bobbin 23 by a preset length, the spindle shaft 111 stops rotating and the winding is finished.

  The spinning machine 2 of the present embodiment is configured as a so-called simultaneous doffing type. This type of spinning machine 2 has a large number of bobbins 23 arranged in a row and stocked in a row via an empty bobbin return path 97, which will be described later. 23 are simultaneously set on the spindle shaft 111 of each spinning unit 32, and the yarn is wound simultaneously. When the winding of the yarn is completed, all bobbins 23 (actual bobbins) are doffed all at once by the doffing device, and empty from the tray 50 on which the empty bobbins 23 waiting at appropriate positions are placed. The bobbin 23 is extracted, and the bobbin 23 (actual bobbin) is inserted into the tray 50. The extracted empty bobbin 23 is set on the spindle shaft 111, and the yarn is wound by the spinning machine 2. The bobbin 23 doffed by the spinning machine 2 and placed on the tray 50 is introduced into the bobbin automatic supply device 6 by being conveyed through the actual bobbin introduction path 91.

  When the bobbin automatic supply device 6 receives the tray 50 loaded with the bobbin 23 (actual bobbin) from the spinning machine 2, it writes appropriate information on the RF tag 60 of the tray 50, and performs the extraction of the bobbin 23 by the extraction device 7. After that, the tray 50 is configured to be supplied to the winder 3 side. This will be described in detail below.

  As shown in FIG. 1, an RF writer (data writing unit) 4 is disposed on the downstream side of the actual bobbin introduction path 91 of the spinning machine 2. The RF writer 4 is for writing information specifying the spinning unit 32 that spun the bobbin 23 into the RF tag 60. When the tray 50 transported through the actual bobbin introduction path 91 passes the writing position of the RF writer 4, information specifying the spinning unit 32 around which the yarn is wound around the bobbin 23 on the tray 50 is RF-written by the RF writer 4. Recorded in the tag 60.

  The spinning units 32 are arranged in parallel in the longitudinal direction of the spinning machine 2, and the bobbins 23 doffed by simultaneous doffing are mounted on the tray 50, and then in the same order as the arrangement of the spinning units 32. The bobbin introduction path 91 is conveyed. Therefore, by counting the order in which the bobbin 23 is introduced into the actual bobbin introduction path 91, the spinning unit 32 in which the bobbin 23 is spun can be specified. For example, the weight of the spinning unit 32a arranged on the most downstream side (the left end in FIG. 2) is placed on the RF tag 60 of the tray 50 that has passed the reading position of the RF writer 4 first after simultaneous duffing. No. as the number. 1 is memorized. The RF tag 60 of the tray 50 transported next to the tray 50 has a No. as the spindle number of the second spinning unit 32b from the left in FIG. 2 is memorized. Similarly, the weight number is assigned to the RF tag 60 of the newly transported tray. 3, no. 4 and so on. As a result, information (weight number) that identifies the spinning unit 32 that has wound the bobbin 23 on the tray 50 is stored in the RF tag 60 of the tray 50 that passes the writing position of the RF writer 4. become.

  Further, the RF writer 4 of the present embodiment is configured to write duffing information together with the above-described weight number. The duffing information here is information indicating the timing when the duffing is performed, such as the time when the simultaneous duffing is performed or the number of duffing.

  The reason why duffing information (such as the duffing time) is recorded in the RF tag 60 together with the weight number is as follows. That is, in the bobbin automatic supply device 6 and the winder 3 (downstream of the spinning machine 2), there may be a tray 50 having the same weight number stored in the RF tag 60. For example, before the winding operation of the bobbin 23 sent to the winder 3 side at the time of the previous doffing is finished, the next doffing is performed and a new group of bobbins 23 is introduced into the bobbin automatic supply device 6 Is the case. Even in such a case, if the duffing information is stored in the RF tag 60, the bobbin 23 having the same weight number can be distinguished as a different bobbin 23 by referring to the doffing information. In addition to the above information, the RF writer 4 of the present embodiment also stores the lot number, the number of the spinning machine 2 (number assigned to each spinning machine 2 when a plurality of spinning machines 2 are provided), and the like in the RF tag 60. It is possible. In the following description, information (weight number and doffing information) for specifying the bobbin 23 written in the RF tag 60 may be referred to as bobbin information.

  The downstream end of the actual bobbin introduction path 91 is connected to the upstream end of the actual bobbin conveyance path 92. The actual bobbin conveyance path 92 connects the bobbin automatic supply device 6 and the winder 3. The tray 50 in which predetermined information is written on the RF tag 60 by the RF writer 4 is transported to the winder 3 along the actual bobbin transport path 92.

  The bobbin automatic supply device 6 includes a mouthing device 7, and this mouthing device 7 is disposed on the actual bobbin transport path 92 and upstream of the winder 3. In order to make it easy for the winder 3 to catch the yarn of the bobbin 23, the mouthing device 7 performs the mouthing of the bobbin 23. Briefly, the lead-out device 7 unwinds the yarn from the surface of the bobbin 23 by causing a suction flow to act on the bobbin 23 that has been transported through the actual bobbin transport path 92 on the tray 50. The unwound yarn end is inserted into the cylindrical bobbin 23. In this way, the yarn end of the bobbin 23 can be easily captured in the winder 3 on the downstream side of the outlet device 7.

  It should be noted that the extraction is not always successful in the extraction device 7, and the extraction may fail. In this case, the tray 50 on which the bobbin 23 whose extraction has failed is sent out to the return bobbin conveyance path 93. The return bobbin conveyance path 93 is branched from the actual bobbin conveyance path 92 immediately downstream of the dispensing device 7 and is configured to be bent in a loop and connected to the upstream end of the actual bobbin conveyance path 92. ing. With the above configuration, the bobbin 23 that has failed to be delivered is conveyed along the return bobbin conveyance path 93, and is then returned to the upstream side of the dispensing device 7 again. As a result, even if the extraction fails, the extraction processing by the extraction device 7 is automatically re-executed, so that there is no need for the operator to deal with every extraction error.

  Next, the winder 3 will be described. As shown in FIGS. 1 and 2, the winder 3 includes a plurality of winding units 31, an RF reader (data reading unit) 5 arranged for each winding unit 31, and a machine control device ( Centralized control unit) 11. The winder 3 also includes a yarn quality monitoring unit 21 for monitoring the state of the yarn being wound by each winding unit 31.

  The yarn quality monitoring unit 21 includes a clearer 15 disposed in each winding unit 31 and a clearer control box (CCB) 12 to which the clearer 15 is connected.

  As shown in FIG. 1, the winder 3 is provided with a plurality of bobbin supply paths 95 branched from the actual bobbin transport path 92. The plurality of bobbin supply paths 95 are provided corresponding to the plurality of winding units 31 provided in the winder 3. With the plurality of bobbin supply paths 95, the bobbins 23 that have been transported through the actual bobbin transport path 92 can be distributed to the winding units 31. Specifically, it is as follows.

  Each bobbin supply path 95 has a predetermined length, and is configured such that a plurality of bobbins 23 can be stocked side by side on the bobbin supply path 95. Further, a guide member (not shown) is disposed at the upstream end of each bobbin supply path 95, and the bobbin 23 conveyed through the actual bobbin conveyance path 92 is placed in the bobbin supply path 95 by the guide member. It is designed to be introduced naturally. On the other hand, if there is not enough space for introducing the bobbin 23 in the bobbin supply path 95 (when the number of stocked bobbins 23 has reached the upper limit), try to introduce a new bobbin 23 into the bobbin supply path 95. Is blocked by the bobbin in the bobbin supply path 95. At this time, the bobbin 23 that has been prevented from being introduced into the bobbin supply path 95 is directly conveyed downstream through the actual bobbin conveyance path 92 and is introduced into another bobbin supply path 95 in which a space is available. As described above, the bobbins 23 sent from the spinning machine 2 can be distributed to the winding units 31.

  On the other hand, when there is no bobbin supply path 95 in which the space where the bobbin 23 can be introduced is empty, the bobbin 23 is introduced into the bobbin standby loop 94 and conveyed through the bobbin standby loop 94. The bobbin standby loop 94 branches from the most downstream side of the actual bobbin conveyance path 92 and is connected to a position upstream of the branch portion between the actual bobbin conveyance path 92 and the most upstream bobbin supply path 95. It is configured. Therefore, the bobbin 23 continues to circulate through a loop path constituted by the bobbin standby loop 94 and the actual bobbin conveyance path 92 until a space in which one of the bobbin supply paths 95 can store the bobbin becomes free.

  Next, the configuration of the winding unit 31 will be described in detail with reference to FIG. As shown in FIG. 5, the winding unit 31 is for winding the yarn from the actual bobbin onto the winding bobbin 22 to form the package 30. The winding unit 31 traverses the yarn and drives the winding bobbin 22. A winding drum (traverse drum) 24 is provided. In addition, the winding unit 31 of the present embodiment is configured so that tension is sequentially applied from the bobbin 23 side to the yarn traveling path between the bobbin 23 and the winding drum 24 set at an appropriate position for performing the unwinding operation. The application device 13, the yarn joining device 14, and a clearer (yarn quality measuring device) 15 are arranged.

  The tension applying device 13 applies a predetermined tension to the traveling yarn. The tension applying device 13 is a gate type device in which movable comb teeth are arranged with respect to fixed comb teeth. The movable comb teeth can be rotated by a rotary solenoid so that the comb teeth are engaged or released. The tension applying device 13 can apply a certain tension to the wound yarn and improve the quality of the package 30.

  The yarn joining device 14 includes a lower thread on the bobbin 23 side and an upper thread on the package 30 side when the clearer 15 detects a yarn defect, or when the yarn breaks during unwinding from the bobbin 23. Is used for piecing. As the yarn splicing device 14, a mechanical type, a type using a fluid such as compressed air, or the like can be used. On the lower side and the upper side of the yarn joining device 14, a lower thread guide pipe 25 that sucks and captures and guides the lower thread on the bobbin 23 side, and an upper thread guide pipe 26 that sucks and captures and guides the upper thread on the package 30 side. And are provided.

  The clearer 15 is configured to monitor the thickness of the yarn with an appropriate sensor and transmit the yarn quality information to the CCB 12. By appropriately analyzing the yarn quality information in the CCB 12, it is possible to detect yarn defects and the amount of fluff. In addition, the clearer 15 can also function as a sensor that simply detects the presence or absence of a yarn. Further, a cutting means is provided in the vicinity of the clearer 15 so that when the clearer 15 detects a yarn defect, it can be removed.

  The yarn unwound from the bobbin 23 is wound on a winding bobbin 22 arranged on the downstream side of the yarn joining device 14. The take-up bobbin 22 is driven by rotating a take-up drum 24 disposed opposite to the take-up bobbin 22. A rotation sensor 27 is attached to the winding drum 24 and outputs a rotation pulse signal every time the winding drum 24 rotates by a predetermined angle. The winding unit 31 of the present embodiment is configured so that the rotational speed of the winding drum 24 can be calculated by measuring the number of pulses per time.

  With the above configuration, when the bobbin 23 conveyed by the bobbin supply path 95 is set at an appropriate position (winding position) of the winding unit 31, the winding drum 24 is driven and unwound from the bobbin 23. The wound yarn is wound around the winding bobbin 22 to form a package 30 having a predetermined length.

  The RF reader 5 is arranged in the bobbin supply path 95 so that the information stored in the RF tag can be read from the RF tag 60 of the tray 50 on which the bobbin 23 taken up by the take-up unit 31 is placed. ing. Information read by the RF reader 5 is transmitted to the machine base control device 11.

  As shown in FIG. 2, the machine control device 11 includes a display 16 as display means and an input key 17 as operation means. The display 16 is for displaying the status of each winding unit 31. The input key 17 is for an operator to set a winding condition or the like.

  As described above, the bobbin information (weight number and doffing information) read by the RF reader is input to the machine base control device 11, and the bobbin 23 currently wound by the winding unit 31 determines which spinning machine. It is possible to specify whether the yarn is wound around the unit 32.

  Based on the yarn quality information transmitted from the clearer 15, the CCB 12 performs a determination process such as whether or not a yarn defect has occurred. As shown in FIG. 2, the CCB 12 has a display (notification unit) 18 as display means, and displays various information such as information related to yarn defects and information generated based on yarn defects on the display 18. It is configured to be able to. The CCB 12 is electrically connected to the machine base control device 11 and configured to exchange various information with the machine base control device 11.

  Further, as shown in FIG. 5, the bobbin supply path 95 is laid below the winding unit 31. The bobbin 23 supplied to the winding unit 31 is conveyed by the bobbin supply path 95 to the winding position. During the winding of the yarn, the bobbin 23 is stopped at the winding position, so that the conveyance of the tray 50 by the bobbin supply path 95 is temporarily stopped.

  Further, as described above, the bobbin supply path 95 is configured so that a plurality of bobbins 23 can be stocked. As shown in FIG. 5, the stocked bobbins 23 are arranged in a line on a bobbin supply path 95, and the bobbin 23 on the most downstream side of the bobbin supply path 95 is used to supply yarn by the winding unit 31. It is the target of winding. In FIG. 5, the position of the rightmost bobbin 23 among the bobbins depicted in the drawing is the winding position.

  Further, the unwinding of the yarn from the bobbin 23 is performed in a state where the bobbin 23 is placed on the tray 50 as shown in FIG. When the bobbin 23 runs out of yarn and becomes an empty bobbin 23, the tray 50 is conveyed by the bobbin supply path 95. As a result, the empty bobbin 23 is sent to the downstream side while riding on the tray 50 and is discharged to the empty bobbin conveyance path 96 (described later).

  On the other hand, as the empty bobbin 23 in the winding position is sent to the downstream side, each bobbin 23 stocked in the bobbin supply path 95 is also sent to the downstream side. Thereby, since the new bobbin 23 is set at the winding position, the yarn can be unwound from the new bobbin 23 and the winding can be resumed. In addition, by discharging the empty bobbin from the bobbin supply path 95, a space for stocking the bobbin 23 in the bobbin supply path 95 is newly vacated. As a result, the bobbin 23 being transported through the actual bobbin transport path 92 is supplied to the bobbin supply path 95.

  As shown in FIG. 1, the downstream ends of the plurality of bobbin supply paths 95 are configured to join the empty bobbin conveyance path 96. The empty bobbin conveyance path 96 connects the winder 3 and the bobbin automatic supply device 6. The empty bobbin 23 discharged from each winding unit 31 is returned to the bobbin automatic supply device 6 by being conveyed through the empty bobbin conveyance path 96.

  In the automatic bobbin supplying device 6, the empty bobbin conveyance path 96 is connected in the middle of the return bobbin conveyance path 93. On the other hand, in the return bobbin conveyance path 93, an empty bobbin return path 97 is branched from a position downstream of the position where the empty bobbin conveyance path 96 is connected. The empty bobbin that has returned to the bobbin automatic supply device 6 through the empty bobbin conveyance path 96 passes through a part of the return bobbin conveyance path 93, and then is transferred to the empty bobbin return path 97 by a path switching mechanism (not shown). be introduced. The empty bobbin return path 97 connects the bobbin automatic supply device 6 and the spinning machine 2. The automatic bobbin supply device 6 is configured to return the empty bobbin 23 to the spinning machine 2 by conveying the empty bobbin 23 through the empty bobbin return path 97.

  As described above, the bobbin 23 can be circulated between the spinning machine 2 and the winder 3 by the loop-shaped tray conveyance path 90 that connects the spinning machine 2 and the winder 3.

  Actually, in addition to the empty bobbin, the actual bobbin and the defective bobbin are conveyed in the empty bobbin conveyance path 96 in a state of being mixed randomly. Therefore, a configuration for separating and appropriately processing empty bobbins, real bobbins, and defective bobbins conveyed in a mixed manner is required. This point will be described in detail below.

  First, a case where an actual bobbin (bobbin with a yarn remaining) is conveyed through the empty bobbin conveyance path 96 will be described. For example, when yarn breakage occurs during winding of the yarn in the winding unit 31, yarn joining by the yarn joining device 14 is performed. At this time, the winding unit 31 generates a suction flow at the tip of the lower thread guide pipe 25, sucks and captures the thread end on the bobbin 23 side, guides it to the yarn joining device 14, and the yarn joining device 14 Perform splicing with the upper thread.

  However, when the thread end on the bobbin 23 side cannot be sucked and captured by the lower thread guide pipe 23, for example, when the thread end is wrapped around the bobbin 23 or when the thread is broken near the bobbin 23, The yarn joining by the yarn joining device 14 cannot be executed. In such a case, the winding unit 31 gives up capturing the yarn end of the bobbin 23 and discharges the bobbin 23 that cannot capture the yarn end to the empty bobbin conveyance path 96. At the same time, the stocked bobbin 23 is conveyed downstream through the bobbin supply path 95 and set at the winding position. Since this new bobbin 23 has been spouted by the spouting device 7, it is possible to easily catch the yarn end and perform piecing. As described above, even when the yarn end cannot be caught when the yarn breaks, the bobbin 23 which cannot catch the yarn end is discharged and a new bobbin 23 is set instead, thereby performing yarn splicing and winding. You can resume.

  On the other hand, the bobbin 23 that could not catch the yarn end is conveyed through the empty bobbin conveyance path 96. Here, as described above, the empty bobbin transport path 96 also transports the empty bobbin sent out from the other winding unit 31. Accordingly, the bobbin 23 that has not been able to catch the yarn end is mixed with the empty bobbin, conveyed through the empty bobbin conveyance path 96, and introduced into the return bobbin conveyance path 93.

  Here, as shown in FIG. 1, the empty bobbin discriminating device 8 is located on the return bobbin conveyance path 93 and upstream of the branch portion between the return bobbin conveyance path 93 and the empty bobbin return path 97. Is provided. The empty bobbin determination device 8 is configured to inspect with an appropriate sensor whether or not the bobbin 23 conveyed through the return bobbin conveyance path 93 is an empty bobbin. Further, a path switching mechanism (not shown) is provided at a branch portion between the return bobbin conveyance path 93 and the empty bobbin return path 97. Then, the path switching mechanism sends out the bobbin 23 determined that the empty bobbin determination device 8 is an empty bobbin to the empty bobbin return path 97 side, and the bobbin 23 determined by the empty bobbin determination device 8 not to be an empty bobbin as it is. The return bobbin conveyance path 93 is configured to be conveyed.

  With the above configuration, only the empty bobbin can be returned to the spinning machine 2. Note that the bobbin 23 (the bobbin in which the yarn remains) that is determined not to be an empty bobbin by the empty bobbin determination device 8 is conveyed through the return bobbin conveyance path 93. Then, the remaining yarn amount is measured by an unillustrated remaining yarn amount detecting device. The bobbin 23 whose residual yarn amount is determined to be minimal is removed by a residual yarn processing device (not shown). The bobbin 23 having a sufficient amount of remaining yarn is subjected to an extraction process by the extraction device 7. As described above, even if the bobbin 23 has not been able to catch the yarn end by the winding unit 31, the yarn can be unwound again by the winding unit 31 by being squeezed by the squeezing device 7.

  Next, a case where a defective bobbin (a bobbin around which a defective yarn is wound) is conveyed through the empty bobbin conveying path 96 will be described.

  In the spinning unit 32, for example, when the draft roller or the apron belt 105 is damaged or worn, periodic thickness unevenness may occur in the yarn produced by the spinning unit 32. This is because the draft roller or the apron belt contacts the yarn while rotating and conveys the yarn while stretching. Further, when the traveler 114 is worn, the amount of yarn fluff tends to increase. In the following description, considering that a yarn having uneven thickness or a yarn having a large amount of fluff is a defective yarn having a low commercial value, the bobbin 23 around which such a defective yarn is wound is referred to as a “defective bobbin”. Sometimes called. In order to prevent the defective yarn from being mixed into the package 30, it is desirable that the winding unit 31 can automatically detect and eliminate the defective bobbin.

  Therefore, the CCB 12 of the present embodiment detects the thickness and fluff of the yarn unwound from the bobbin 23 based on the yarn quality information from the clearer 15. And CCB12 of this embodiment is currently winding in the said winding unit 31 when the magnitude | size of the yarn thickness fluctuation | variation detected by the clearer 15 of a certain winding unit 31, and the amount of fluff exceed a predetermined allowable range. The bobbin is determined to be a defective bobbin.

  When a defective bobbin is detected, the winding unit 31 discharges the defective bobbin to the empty bobbin conveyance path 96 as it is (without remaining yarn) without further unwinding the yarn, and the bobbin supply path 95 The unwinding of the yarn from another bobbin 23 stocked in the head is started. Thereby, it is possible to prevent the yarn having uneven thickness and the yarn having a large amount of fluff from being mixed into the package 30.

  By the way, if the defective bobbin sent out from the winding unit 31 to the empty bobbin conveyance path 96 is introduced into the return bobbin conveyance path 93 (because yarn remains in the defective bobbin), an empty bobbin determination device. In step 8, it is determined that the bobbin is not empty, and is supplied again to the winder 3 via the brewing device 7. Therefore, when the defective bobbin has been transported through the empty bobbin transport path 96, the automatic bobbin supply device 6 retracts the defective bobbin to the defective bobbin standby path 98 without introducing it into the return bobbin transport path 93. It is configured.

  Specifically, it is as follows. When the CCB 12 detects a defective bobbin based on the yarn quality information from the clearer 15 of a winding unit 31, the CCB 12 transmits information indicating that the defective bobbin is detected by the winding unit 31 to the machine control device 11. It is configured. As described above, when the bobbin 23 is wound by the winding unit 31, information stored in the RF tag 60 of the tray 50 on which the bobbin 23 is mounted (information for specifying the bobbin 23). Is read by the RF reader 5, and the information is input to the machine control device 11. Then, when a defective bobbin is detected in the winding unit 31, the machine base control device 11 informs that fact and the bobbin of the bobbin 23 (the defective bobbin) currently wound in the winding unit 31. Information is stored in association with each other. Therefore, information indicating which bobbin 23 is a defective bobbin is stored in the machine control device 11.

  On the other hand, as shown in FIG. 1, the defective bobbin standby path 98 is branched from the empty bobbin transport path 96 at a position upstream from the junction of the empty bobbin transport path 96 and the return bobbin transport path 93. It has been. Further, the RF reader 9 is disposed on the empty bobbin conveyance path 96 and upstream of the branch portion between the empty bobbin conveyance path 96 and the defective bobbin standby path 98. The RF reader 9 is configured to read the stored contents of the RF tag 60 provided in the tray 50 transported through the empty bobbin transport path 96 and transmit the stored contents to the machine control device 11. Further, a path switching mechanism (not shown) is provided at a branch portion between the empty bobbin conveyance path 96 and the defective bobbin standby path 98. This path switching mechanism is configured to be controllable by the machine base control device 11.

  The machine base control device 11 compares the information sent from the RF reader 9 with the information stored by itself (information about which bobbin 23 is a defective bobbin), thereby determining the position of the RF reader 9. It is configured to determine whether or not the bobbin 23 on which the tray 50 that has passed is loaded is a defective bobbin. Then, the path switching mechanism sends out the bobbin 23 determined by the machine control device 11 to be a defective bobbin to the defective bobbin standby path 98 side, and the bobbin 23 determined by the machine control device 11 not to be a defective bobbin as it is. The empty bobbin conveyance path 96 is configured to be conveyed.

  The defective bobbin standby path 98 has a certain length, and the downstream end of the defective bobbin standby path 98 is dead end. As a result, a plurality of trays 50 on which defective bobbins are placed can be waited on the defective bobbin standby path 98.

  When the tray 50 with the defective bobbin is stored in the defective bobbin standby path 98 to a certain extent, the operator removes the defective bobbin from each tray 50 and replaces it with an empty bobbin. Then, when the operator performs an appropriate operation, the defective bobbin standby path 98 is driven in reverse. As a result, the tray 50 stored in the defective bobbin standby path 98 is introduced into the replaced bobbin return path 99 with the replaced empty bobbin mounted thereon.

  As shown in FIG. 1, the replaced bobbin return path 99 branches off from a defective bobbin standby path 98 and is connected to an empty bobbin return path 97. Then, the tray 50 with the empty bobbin replaced from the defective bobbin is introduced into the empty bobbin return path 97 via the replaced bobbin return path 99 and returned to the spinning machine 2.

  As described above, the spinning winder 1 of the present embodiment has the spinning machine 2 and the winder 3 without stopping the conveyance of the tray 50 even when the empty bobbin, the real bobbin, and the defective bobbin are mixed. The bobbin 23 can be appropriately exchanged between the two.

  Next, the structure for notifying maintenance information in the textile machine management system of the present embodiment will be described.

  When a defective bobbin is detected in the winding unit 31, it is necessary to perform maintenance promptly in order to remove the cause of the defect. However, in general, a textile machine has a large number of units, and there are a plurality of parts that need to be inspected in each unit. For this reason, in the past, much effort has been required just to identify parts that require maintenance.

  Accordingly, the textile machine management system according to the present embodiment is configured to display maintenance information on the display 18 when a defective bobbin is detected by the winding unit 31. Here, the maintenance information is information indicating a warning that maintenance is necessary, a unit that requires maintenance, and a part of the unit that requires maintenance in particular. This will be specifically described below.

  First, the clearer 15 for detecting a defective bobbin will be described in detail with reference to FIG. FIG. 6 is a block diagram illustrating a configuration of the yarn quality monitoring unit 21 according to the present embodiment.

  As shown in FIG. 6, the clearer 15 of the present embodiment includes a first thread thickness sensor 43. The first thread thickness sensor 43 includes a light emitting unit (not shown) and a light receiving unit (not shown) that receives light from the light emitting unit and detects the amount of light received. Further, the clearer 15 is installed so that the yarn being wound in the winding unit 31 passes between the light emitting unit and the light receiving unit. The greater the thickness of the thread passing between the light emitting unit and the light receiving unit, the lower the intensity of light received by the light receiving unit. Therefore, the thickness of the thread can be detected by the first thread thickness sensor 43.

  The first yarn thickness sensor 43 can also detect yarn fluff. That is, the fluff appears so as to spread radially from the yarn, so that the apparent thickness of the yarn increases when the amount of fluff is large. Therefore, the greater the amount of fluff, the lower the intensity of light received by the light receiving unit, and the first yarn thickness sensor 43 can detect the amount of fluff.

  The first thread thickness sensor 43 is connected to the first A / D converter 45 and the second A / D converter 46. Each A / D converter samples the analog waveform output from the first thread thickness sensor 43 and converts it into digital waveform data. The waveform data sampled by the first A / D converter 45 is transmitted to the CCB 12. The digital waveform data output from the first A / D converter 45 may be referred to as “yarn quality information” in the following description. The second A / D converter 46 will be described later.

  In the CCB 12, based on the yarn quality information, yarn defect determination processing, periodic yarn thickness unevenness detection, fluff amount measurement processing, and the like are performed. The periodic yarn thickness unevenness can be detected by, for example, subjecting the yarn quality information, which is digital waveform data, to a known FFT (Fast Fourier Transform) to perform periodic analysis using appropriate means. .

  By the way, the periodic thickness unevenness generated in the yarn in the textile machine is a thickness unevenness that repeatedly appears at regular intervals. That is, the term “periodic” refers to the yarn length period (not the time period). Here, when it is attempted to accurately obtain periodic unevenness appearing at constant length intervals by FFT, the number of samples per unit length of the yarn in the waveform data must be constant. However, since the yarn winding speed in the winding unit 31 is not constant, if the number of samples per unit length is to be constant, the sampling frequency by the first A / D converter 45 is changed in proportion to the yarn speed. There is a need. Therefore, it is important to obtain an accurate value of the yarn speed when trying to accurately obtain the yarn thickness periodic unevenness. Therefore, the clearer 15 of the present embodiment is configured as follows in order to detect an accurate yarn speed.

  As shown in FIG. 6, the clearer 15 includes a second A / D converter 46, a second thread thickness sensor 44, and a CPU 47. The second thread thickness sensor 44 has the same configuration as the first thread thickness sensor 43, and is disposed upstream of the first thread thickness sensor 43 in the yarn traveling direction. The second A / D converter 46 A / D converts analog signals from the first thread thickness sensor 43 and the second thread thickness sensor 44.

  The CPU 47 controls the sampling frequency of the second A / D converter 46. On the other hand, a rotation pulse signal from the rotation sensor 27 is input to the CPU 47. The CPU 47 is configured to change the sampling frequency of the second A / D converter 46 in proportion to the frequency of the rotation pulse signal. That is, the sampling interval of the second A / D converter 46 is shortened as the rotational speed of the winding drum 24 increases (as the yarn is wound at a higher speed).

  The second A / D converter 46 outputs a digital waveform obtained by sampling signals from the two thread thickness sensors 43 and 44 to the CPU 47. Here, since the first thread thickness sensor 43 and the second thread thickness sensor 44 measure the same thread, the second A / D converter 46 outputs two digital signals having the same waveform. However, since the first thread thickness sensor 43 is disposed downstream of the second thread thickness sensor 44 in the yarn traveling direction, the waveform of the signal from the first thread thickness sensor 43 is the second thread thickness sensor 43. It is later than the waveform of the signal from the sensor 44.

  On the other hand, the CPU 47 obtains a delay amount ΔT that indicates how much the waveform from the first thread thickness sensor 43 is behind the waveform from the second thread thickness sensor 44. This delay amount ΔT can be obtained, for example, by performing pattern matching between the digital waveform from the first thread thickness sensor 43 and the digital waveform from the second thread thickness sensor 44. In the present embodiment, as described above, the sampling frequency of the second A / D converter 46 is changed according to the yarn speed. Therefore, even if the yarn speed changes in the middle, the second A / D converter 46 outputs it. The digital waveform is not distorted greatly. Therefore, the pattern matching can be performed with high accuracy.

  Here, the distance L between the first thread thickness sensor 43 and the second thread thickness sensor 44 is known. Accordingly, the yarn speed V can be obtained from V = L / ΔT. Since the yarn speed V is a value obtained by directly observing the yarn passing through the position of the clearer 15, it can be said that it is an accurate value as the yarn speed at the position of the clearer 15.

  The CPU 47 changes the sampling frequency of the first A / D converter 45 in proportion to the yarn speed V. Thus, by changing the sampling frequency in accordance with the accurate yarn speed V, digital waveform data (yarn quality information) having a constant number of samples per unit length of the yarn can be obtained.

  The yarn quality information from the first A / D converter 45 is output to the CCB 12. In the CCB 12, periodic analysis such as FFT calculation is performed on the yarn quality information sampled as described above, and periodic variations in the yarn thickness are detected.

  A spectrogram illustrating the result of periodic analysis of the yarn quality information in the CCB 12 is shown in FIG. In the spectrogram of FIG. 7, the horizontal axis represents the period (wavelength) of the periodic signal included in the waveform data (yarn quality information), and the vertical axis represents the intensity of the signal. When there is no thickness unevenness in the yarn quality information, the spectrogram is a smooth curve. On the other hand, if the yarn quality information has periodic thickness unevenness, a peak appears at a position corresponding to the thickness unevenness period as shown in FIG.

  The CCB 12 is a case where periodic yarn thickness unevenness is detected in the yarn of the bobbin 23 being wound in a winding unit 31, and the thickness unevenness strength (spectrogram peak strength) is allowed. When the range is exceeded, the periodic thickness unevenness is regarded as defective, and information indicating that a defective bobbin is detected is transmitted to the machine control device 11.

  As described above, the CCB 12 can measure the amount of fluff based on the yarn quality information. The increase in the amount of fluff appears not as a periodic change as described above, but as an overall tendency of the yarn. Therefore, when the CCB 12 detects that the yarn thickness indicated by the yarn quality information has increased as a whole, the CCB 12 determines that the amount of fluff has increased.

  CCB 12 is a case where an increase in the amount of fluff is detected on the yarn of bobbin 23 being wound in a winding unit 31, and the amount of fluff exceeds the predetermined allowable range. Is transmitted to the machine control device 11 as information indicating that a defective bobbin has been detected.

  As described above, the CCB 12 can detect a defective bobbin based on the yarn quality information. That is, based on the yarn quality information, it can be detected that there is a unit requiring maintenance.

  Next, a configuration for identifying a maintenance-required unit (corresponding unit) that is a unit that requires maintenance in response to a defective bobbin thread will be described.

  By the way, the cause of the defect of the defective bobbin is not always in the spinning unit 32. That is, each fine spinning unit 32 is supplied with a roving bobbin (a bobbin around which a roving yarn is wound) from a roving unit (pre-processing unit) in charge of the pre-process, and receives the roving from the roving bobbin. A spun yarn is produced by drawing and twisting. Therefore, even if this roving unit has some trouble, a defective bobbin can be formed in the spinning unit 32. For this reason, even if a defective bobbin is detected, it cannot be determined that the spinning unit 32 on which the defective bobbin is formed needs to be maintained, and there may be a case where maintenance on the rough spinning unit side is necessary.

  Therefore, first, a rough spinning machine (pre-process machine) in charge of the pre-process of the spinning machine 2 will be briefly described. FIG. 2 schematically shows a front view of the roving machine 20. The roving machine 20 includes a plurality of roving units 33. In addition, when it is necessary to distinguish each roving unit 33, from the left side of the drawing of the roving machine 20, an alphabet is added to the end of the code so that the roving unit 33a, the roving unit 33b,... It shall be written.

  The roving unit 33 is for generating a roving yarn from a sliver and forming a roving bobbin obtained by winding the roving yarn around a bobbin. Since the configuration of the roving unit 33 is well known, illustration is omitted. However, each roving unit 33 is lightly twisted on a draft portion having a draft roller and an apron belt for extending the sliver and a sliver drawn by the draft portion. And a flyer for winding on a bobbin while hanging.

  The roving machine 20 of this embodiment is configured as a so-called simultaneous doffing type. This type of roving machine starts winding of the roving yarn at the same time, and when the winding of the roving yarn is finished, the hoisting is performed all at once. The roving units 33 of the roving machine 20 of the present embodiment are arranged in a line in the longitudinal direction of the roving machine 20. Then, the doffed roving bobbins are sent from the roving units 33 corresponding to the order in which the spinning units 32 are arranged with respect to the spinning units 32 arranged in a row in the same manner as the roving units 33. Supplied.

  That is, for example, in FIG. 2, the roving bobbin from the leftmost roving unit 33a goes to the leftmost spinning unit 32a, and the roving bobbin from the second roving unit 33b from the left goes to the second fine spinning unit 33a. To the spinning unit 32b, the correspondence between a certain spinning unit 32 and the roving unit 33 remains unchanged.

  In the present embodiment, more fine spinning units 32 are provided than the rough spinning units 33. Therefore, each roving unit 33 is configured to supply roving bobbins to a plurality of spinning units 32. In this case, the corresponding pattern of which spinning unit 32 receives the supply of the roving bobbin from which roving unit 33 is repeated in the longitudinal direction of the spinning machine 2.

  For example, as shown in FIG. 2, in the longitudinal direction of the spinning machine 2, the same number of spinning units 32 as the roving units 33 are grouped together so that a fine unit such as a first unit group 321, a second unit group 322,. A spinning unit group is formed. The roving bobbins are supplied from the roving units 33 corresponding to the order in which the respective spinning units 32 are arranged to the respective spinning units 32 in the first unit group 321. Similarly, the roving yarn bobbins are supplied to the spinning units 32 in the second unit group 322 from the roving units 33 corresponding to the order in which the spinning units 32 are arranged. In this way, each roving unit 33 supplies the roving bobbins to the corresponding plurality of spinning units 32.

  Based on the above points, the maintenance-required unit can be specified as follows.

  As described above, the machine control device 11 determines which spinning unit 32 has the bobbin 23 wound by the winding unit 31 based on the bobbin information read by the RF reader 5 of each winding unit 31. Can be identified. Accordingly, when a defective bobbin is detected by a certain winding unit 31, the machine control device 11 can identify the spinning unit 32 that has formed the defective bobbin.

  Then, when the machine control device 11 specifies the spinning unit 32 in which the defective bobbin detected by a certain winding unit 31 is formed, the machine control device 11 checks whether or not the defective bobbin is formed in another spinning unit 32.

  For example, it is assumed that a failure occurs in a certain roving unit 33 and a defective yarn is generated due to this. In this case, the influence of the malfunction of the roving unit 33 extends to the plurality of spinning units 32 to which the roving unit 33 supplies the roving bobbins. Accordingly, when a plurality of spinning units 32 to which a roving bobbin is supplied from a roving unit 33 forms a defective yarn, and the characteristics of the defective yarn are common to each spinning unit 32 (for example, a plurality of spinning units 32). In the case where a similar period unevenness is detected in the defective yarn generated in the fine spinning unit 32), it can be considered that the cause of the defective defective yarn is in the roving unit 33.

  Specifically, in the case of FIG. 2, the bobbin 23 formed by the spinning unit 32a and the spinning unit 32e is detected as a defective bobbin obtained by winding a defective yarn having a non-uniformity in yarn thickness, When the period of the periodic unevenness is common, it can be specified that the roving unit 33a which is a common roving bobbin supply source for the two spinning units needs maintenance.

  On the other hand, it is assumed that a problem occurs in a certain spinning unit 32 and a defective bobbin is formed due to this. In this case, the malfunction in the spinning unit 32 does not affect the bobbin formed in the other spinning unit 32. Therefore, when a defective yarn having specific characteristics is formed only from one spinning unit 32, it can be considered that the cause of the failure of the defective yarn is the spinning unit 32 that generated the defective yarn. .

  Specifically, in the case of FIG. 2, when only the bobbin formed by the spinning unit 32a is detected as a defective bobbin and the bobbin formed by the spinning unit 32e is not detected as a defective bobbin, maintenance is required. It can be specified that the spinning unit 32a (not the roving unit 33a).

  As described above, the machine base control device 11 can specify the maintenance-required unit based on the bobbin information of the defective bobbin. And the machine control apparatus 11 will transmit the information which specifies the said maintenance required unit to CCB12, if a maintenance required unit is specified.

  Next, a configuration for specifying a maintenance required site (corresponding site) that is a site that requires maintenance corresponding to a defective bobbin in the maintenance required unit will be described.

  As described above, when there is a problem such as breakage or wear in the draft roller or apron belt 105 provided in the spinning unit 32, the periodic thickness unevenness of the yarn is detected. The same applies to the case where there is a problem with the draft roller or apron belt provided in the roving unit 33. The cycle of the uneven thickness of the yarn varies depending on various conditions such as the diameter of the roller, the length of the belt, and the rotational speed at which the problem occurs. That is, the cycle of the thickness unevenness of the yarn is specific to the roller or belt (the portion requiring maintenance) that has caused the thickness unevenness. Therefore, if the period analysis of the thickness unevenness is performed to obtain the period of the thread thickness unevenness, the maintenance-required part can be specified based on the period.

  In the lower part of FIG. 7, when there is a problem with the draft roller or the apron belt provided in the fine spinning unit 32 and the roving unit 33, it is shown by way of example where the peak appears in the spectrogram correspondingly. Yes. The CCB 12 of the present embodiment stores such a correspondence relationship between the peak position of the spectrum (cycle of yarn thickness unevenness) and the roller or belt in which a problem has occurred.

  With the above configuration, the CCB 12 can identify a site where a defect has occurred based on the peak position of the spectrogram obtained from the yarn quality information. For example, when a spectrogram as shown in FIG. 7 is obtained from the yarn quality information, it can be specified that the apron belt of the spinning unit 32 is defective. The site where such a problem has occurred is a maintenance required site.

  On the other hand, as described above, when the traveler 114 is worn, the amount of fluff increases. Therefore, when the CCB 12 detects an overall increase in the amount of fluff based on the yarn quality information, the traveler 114 identifies the traveler 114 as a maintenance required site.

  As described above, the CCB 12 specifies a maintenance required site based on the yarn quality information. The CCB 12 is configured to display on the display 18 that maintenance is required and a maintenance required site when the maintenance required site is specified. Further, as described above, since the CCB 12 is input with information for specifying a maintenance required unit from the machine base control device 11, this maintenance required unit is also displayed on the display 18.

  The operator of the spinning winder 1 can know the unit that requires maintenance and the part that needs maintenance in the unit by checking the maintenance information displayed on the display 18. Maintenance work can be performed.

  However, as described above, it is not possible to perform maintenance at an appropriate time in advance (before the defective bobbin is formed) simply by notifying a place requiring maintenance afterwards.

  Therefore, the textile machine management system of the present embodiment is configured such that the life of each consumable part provided in each unit can be displayed on the display 18 as maintenance information. Here, the consumable parts are specifically an apron belt provided in the spinning unit 32 and the roving unit 33, and a traveler 114 provided in the spinning unit 32.

  When the apron belt 105 of the spinning unit 32 starts to wear, the yarn thickness unevenness is detected at a period corresponding to the apron belt 105 in the winding unit 31 that winds the bobbin 23 formed by the spinning unit 32. Is done. At this time, it is considered that the strength of the yarn thickness unevenness (spectrogram peak height) becomes stronger as the apron belt 105 is worn. This also applies to the case where the apron belt included in the roving unit 33 is worn.

  Therefore, the CCB 12 is a case where periodic yarn thickness unevenness is detected in the yarn of the bobbin 23 being wound in a certain winding unit 31, and the strength of the thickness unevenness (the intensity of the spectrogram peak) is When it is within the allowable range (that is, when the life of the part has not yet expired), it is determined whether or not the period of the thickness unevenness corresponds to the apron belt. When the thickness unevenness is caused by the apron belt, the CCB 12 identifies the apron belt as a life estimation target part (corresponding part). The CCB 12 estimates the apron belt component life based on the intensity of the peak. For example, when the intensity of the peak is slightly below the boundary value of the allowable range, it can be determined that the apron belt has little remaining part life.

  Further, when the traveler 114 of the spinning unit 32 is worn, an increase in the fluff amount of the yarn is detected in the winding unit 31 that winds the bobbin 23 formed by the spinning unit 32. At this time, the amount of fluff detected is considered to increase as the traveler 114 wears.

  Therefore, the CCB 12 is a case where an increase in the amount of fluff is detected in the yarn of the bobbin 23 being wound in a certain winding unit 31, and the amount of the fluff is within an allowable range (that is, still The traveler 114 is identified as a life estimation target part (corresponding part). The CCB 12 estimates the component life of the traveler 114 based on the amount of fluff. For example, if the amount of fluff is slightly below the boundary value of the allowable range, it can be determined that the component life of the traveler 114 is low.

  Further, when the CCB 12 specifies the life estimation target part, the CCB 12 sends a signal to the machine control device 11 so as to specify the unit (life estimation target unit) corresponding to the yarn thickness unevenness or the increase in the fluff amount. Here, the life estimation target unit refers to a unit having a life estimation target part for which the CCB 12 has estimated the life.

  The machine base control device 11 identifies the life estimation target unit (corresponding unit) based on the bobbin information of the bobbin 23 in which the yarn thickness unevenness or the increase in the fluff amount is detected. This life estimation target unit can be specified in the same manner as the maintenance required unit. When specifying the life estimation target unit, the machine control device 11 transmits information specifying the life estimation target unit to the CCB 12.

  The CCB 12 displays the life estimation target part and the component life on the display 18. Since it is not known from which unit the component life has been estimated by this alone, the life estimation target unit received from the machine control device 11 is also displayed on the display 18.

  The operator of the spinning winder 1 can determine which part of which unit the part whose life is about to expire by checking the display on the display 18. Can be performed at the optimum timing.

  Next, a modification of the above embodiment will be described.

  In the above embodiment, the maintenance information is displayed on the display 18 of the CCB 12. However, instead, the maintenance information may be displayed on the display 16 of the machine control device 11. In this case, if the corresponding part is specified and the state of the corresponding part is estimated on the machine control device 11 side, the structure for specifying and notifying the maintenance information can be realized only by the machine control device 11. it can. As a result, the yarn quality monitoring unit 21 can have a simple configuration (having no function for specifying and notifying maintenance information), and can easily be used for a yarn quality monitoring unit having a conventional configuration. Can be adapted.

  However, in this modified example, the machine base control device 11 must receive the yarn quality information from the yarn quality monitoring unit 21. As described above, when a large amount of data (yarn quality information) must be exchanged between the yarn quality monitoring unit 21 and the machine base control device 11, the configuration of the textile machine management system becomes complicated. In this regard, as in the above-described embodiment, if the CCB 12 on the yarn quality monitoring unit 21 side identifies and notifies the corresponding part and the state of the corresponding part, the yarn quality information is transmitted between the machine control device 11 and the thread quality information. Therefore, the textile machine management system can be configured simply.

  As described above, the textile machine management system of the present embodiment is configured as a textile machine management system of the spinning machine 1 having the spinning machine 2, the winder 3, the bobbin automatic supply device 6, and the display 18. Has been. The spinning machine 2 includes a plurality of spinning units 32 that generate yarn from the roving yarn supplied from the roving machine 20 including a plurality of roving units 33 and wind the yarn around the bobbin 23 to form an actual bobbin. The winder 3 includes a plurality of winding units 31 that unwind the yarn from the actual bobbin and wind it around the package 30. The bobbin automatic supply device 6 places the actual bobbin on the tray 50 and supplies the actual bobbin from the spinning machine 2 to each winding unit 31. Further, the tray 50 includes an RF tag 60 that stores information that can identify the spinning unit 32 that forms the actual bobbin on which the tray 50 is placed as bobbin information. The winder 3 includes a yarn quality monitoring unit 21 that monitors the state of the spun yarn unwound from the actual bobbin by each winding unit 31 and acquires yarn quality information. Each winding unit 31 includes an RF reader 5 that can read the bobbin information from the RF tag 60 of the tray 50 on which the actual bobbin supplied to the winding unit 31 is placed. In addition, when a predetermined feature is detected in the yarn based on the yarn quality information, the textile machine management system corresponds to the feature from the roving unit 33 or the spinning unit 32 based on the bobbin information. The corresponding unit is identified. In addition, the textile machine management system specifies a corresponding part that is a part corresponding to the feature in the corresponding unit based on the yarn quality information, and estimates the state of the corresponding part. And this textile machine management system can notify the said corresponding | compatible unit, the said corresponding | compatible part, and the state of the said corresponding | compatible part by the display 18. FIG.

  That is, when any abnormality is detected in the yarn, the operator can be notified of the unit that is causing the abnormality and the part that is causing the abnormality in the unit. Can be done appropriately. Further, since the state of the site causing the abnormality is also notified, the operator can appropriately determine at which timing maintenance is to be performed. In addition, the thread condition can be automatically analyzed without taking the time and effort required to manually collect and analyze the thread from the actual bobbin, greatly reducing the burden on the operator. be able to.

  In the textile machine management system according to the present embodiment, the display 18 displays the component life of the consumable part as the state of the consumable part.

  As a result, the life of the component can be notified to the operator, so that the operator can accurately grasp when the component should be replaced. Therefore, there is no need to replace parts too early and uselessly, and it is not too late to produce parts of poor quality. Excellent in terms of quality.

  Further, in the textile machine management system of the present embodiment, when the characteristic of the yarn is abnormal, the display 18 displays that maintenance is required at a maintenance required site.

  Thus, when a defective yarn is detected, it is possible to notify the operator that maintenance is necessary and the unit and part that require maintenance. Therefore, the operator can perform maintenance quickly and appropriately, and can recover from the abnormality at an early stage.

  Moreover, the textile machine management system of the present embodiment is configured as follows. In other words, the spinning unit 32 is a ring spinning unit including a traveler 114 for twisting a yarn. Then, when the textile machine management system detects that the fluff amount increases according to the predetermined characteristic as a characteristic of the yarn, it specifies that the corresponding portion corresponding to the increase in the fluff amount is the traveler 114. Based on the amount of fluff, the life of parts of the traveler or the necessity of maintenance is estimated and displayed on the display 18.

  That is, when the traveler 114 is worn, the amount of yarn fluff increases, so it is necessary to replace the traveler 114 at an appropriate time. In this respect, by configuring as described above, it is possible to estimate the lifetime of the traveler or the necessity of maintenance based on the actual fluff amount of the yarn, so that the traveler can be replaced at an appropriate timing.

  Moreover, the textile machine management system of the present embodiment is configured as follows. That is, the fine spinning unit 32 and the roving unit 33 are provided with a draft roller and an apron belt for conveying the yarn or the roving yarn. And when the textile machine management system detects that there is periodic thickness unevenness as a characteristic of the yarn, a draft roller or a corresponding part corresponding to the thickness unevenness based on the period of the thickness unevenness or The apron belt is specified, and the life of parts of the roller or the belt or the necessity of maintenance is estimated and displayed on the display 18 based on the size of the thickness unevenness.

  In other words, when a failure occurs in a member that rotates and conveys a yarn such as a roller or a belt, periodic thickness unevenness occurs in the yarn. This period of thickness unevenness is specific to the roller or belt in which a defect has occurred. Therefore, by configuring as described above, the life of the roller or the belt or the necessity for maintenance can be estimated, so that the replacement or maintenance of the roller or the belt can be performed at an appropriate timing.

  Moreover, the textile machine management system of the present embodiment is configured as follows. That is, each fine spinning unit 32 is configured such that a roving bobbin is supplied only from a specific roving unit 33 among a plurality of roving units 33. Each of the plurality of roving units 33 is configured to supply roving bobbins to the plurality of spinning units 32. The textile machine management system is a case where a common yarn characteristic is detected in an actual bobbin formed by a plurality of spinning units 32, and the plurality of spinning units 32 are separated from a common roving unit 33. When the roving bobbin is supplied, the roving unit 33 is specified as the corresponding unit.

  Thereby, the roving unit 33 which is a corresponding | compatible unit can be pinpointed reliably.

  Moreover, the textile machine management system of the present embodiment is configured as follows. That is, the yarn quality monitoring unit 21 has a display 18. Further, the corresponding part and the state of the corresponding part are specified by the yarn quality monitoring unit 21.

  Thereby, since it is not necessary to transmit enormous yarn quality information to the outside of the yarn quality monitoring unit, the textile machine management system can be configured simply.

  Moreover, the textile machine management system of the present embodiment can be modified as follows. That is, the fine spinning winder 1 includes a machine base control device 11 having a display 16. The machine control device 11 specifies the corresponding part and the state of the corresponding part based on the yarn quality information output by the yarn quality monitoring unit 21.

  In this modification, since the yarn quality monitoring unit 21 does not need to specify the corresponding part and the state of the corresponding part, a yarn quality monitoring unit having a conventional configuration can be used.

  Moreover, the textile machine management system is applied to the fine spinning winder 1 of the present embodiment.

  The fine spinning winder 1 according to the present embodiment can perform maintenance appropriately by applying the textile machine management system, and thus is excellent in terms of the quality of a generated package and maintenance cost.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  The spinning winder to which the textile machine management system of the present invention is applied is not limited to the configuration shown in FIGS. For example, in an actual spinning winder, the number of spinning units and winding units ranges from several tens to several hundreds, but the textile machine management system of the present invention can be applied regardless of the number of units. . Further, a single winding unit may be provided for a plurality of spinning units.

  In the above embodiment, the component life is displayed on the display 18, but the component life may be information “how many days the component can be used”, or “the replacement date of the component is It may be information indicating the replacement time of the part, such as “what month and day”.

  In the embodiment described above, the spindle number and the doffing information are stored in the RF tag 60 and the spinning unit is specified. However, this configuration can be appropriately changed according to circumstances. For example, a unique identification number can be assigned to the tray 50, and the bobbin 23 can be specified based on the identification number.

  The clearer 15 of the above embodiment has a configuration in which the yarn speed is accurately obtained by the two yarn thickness sensors 43 and 44 provided at intervals, but is not limited thereto. For example, a sensor for measuring the yarn speed may be provided separately from the clearer 15. In this case, the clearer 15 may have a normal configuration having only one thread thickness sensor.

  In the above embodiment, the cause of unevenness in the thickness of the yarn and the like is specified retroactively to the roving machine 20 which is the previous process of the spinning machine 2. However, actually, there are other pre-processes such as a drawing machine before the roving machine 20. Thus, even if there is a cause of unevenness in the yarn thickness in the previous process machine in charge of the further previous process of the roving machine 20, by analyzing the cycle of the uneven thickness of the yarn, You can identify if there is.
