In the fine spinning winder as described above, there is a case where it is desired to know how fluff is generated on the spun yarn on a bobbin basis for reference in grasping the operation status of the fine spinning unit. Therefore, it is conceivable to use the clearer fluff detection function provided in the winding unit of the automatic winder.

By the way, the fluffiness (fluff amount) of the spun yarn unwound from the bobbin is small immediately after the start of unwinding, but gradually increases as the remaining yarn amount approaches zero. The relationship shows a certain fluctuation trend. However, since the above-mentioned fluctuation cannot be taken into account in the detection of fluff by the clearer, the amount of fluff generated cannot be analyzed appropriately in units of bobbins.

Therefore, in the conventional spinning winder, one of the bobbins wound with the spinning unit of the spinning machine is extracted as a sample, the yarn is unwound by a predetermined length, and the spinning winder is A method of measuring the amount of fluff with an analyzer provided separately was employed. According to this, since data that can be compared with other bobbins can be obtained with respect to the amount of fluff of the yarn, it is possible to grasp a tendency for each bobbin that a certain bobbin has more fluff than other bobbins. However, a spinning machine often includes a large number of spinning units, and it is very time-consuming to take a sample for all of them and analyze them with an analyzer. On the other hand, if the sample take-out interval for quality inspection is increased, discovery of defects in the spinning unit may be delayed depending on the sample take-out timing, and production efficiency may be reduced.

The present invention has been made in view of the above circumstances, and an object thereof is a management system for a spinning winder capable of automatically analyzing the occurrence tendency of fluff of yarn spun by a spinning unit in units of bobbins. Is to provide.

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 the first aspect of the present invention, the following configuration is provided in a management system for managing a spinning winder including a spinning machine, an automatic winder, and a bobbin transport mechanism. That is, the spinning machine includes a plurality of spinning units that wind the spun yarn around the bobbin. The automatic winder includes a winding unit that unwinds the yarn wound around the bobbin to form a package. The bobbin transport mechanism transports a transport body on which a bobbin around which a yarn is wound by the spinning machine is set to the winding unit. The carrier has a data recording unit capable of recording information for specifying the spinning unit in which a thread is wound around the bobbin set on the carrier. The winding unit includes a fluff detection unit, a yarn length calculation unit, and a data reading unit. The fluff detection unit is for detecting the amount of fluff of the yarn. The yarn length calculation unit is for calculating an unwinding yarn length indicating the length of the yarn unwound from the bobbin. The data reading unit is for reading information in the data recording unit of the bobbin on which the winding operation is performed. The automatic winder records the fluff amount together with the unwinding yarn length when the fluff detection unit detects the fluff amount, and performs a quality inspection of the yarn spun by the spinning unit on a bobbin basis. Is provided.

Thereby, the spinning unit that has spun can be identified based on the information in the data recording unit, so that the quality of the yarn produced by the spinning unit can be inspected in units of bobbins. In addition, since quality inspection can be automatically performed on the production line in parallel with the winding operation, the work of quality inspection can be saved. In addition, since the amount of fluff is recorded in correspondence with the yarn length, it is possible to accurately grasp the tendency of fluff generation indicating which portion of the yarn is fluffy, and to detect and deal with fluff. It becomes possible to carry out efficiently.

In the management system, the spinning unit is preferably configured as a ring spinning unit having a traveler.

This makes it possible to accurately grasp the tendency of fluff generation in units of bobbins, so that it is possible to easily detect an increase in the fluff amount of the entire yarn caused by the deterioration of the traveler due to wear.

The above management system is preferably configured as follows. In other words, the spinning winder includes notifying means configured to be able to identify and notify a spinning unit that requires maintenance. Then, the management system monitors the occurrence tendency of the fluff of the yarn produced by the same spinning unit in units of bobbins, and changes such that the occurrence tendency of the fluff satisfies the determination condition from the past occurrence tendency of the fluff. If indicated, the notification means notifies the user.

By monitoring the change in fluff generation tendency in units of bobbins, it is possible to detect changes in the amount of fluff caused by malfunctions in the spinning unit that occur during system operation in units of bobbins. An operator can be notified of a spinning unit. Accordingly, it becomes possible for the operator to quickly cope with the malfunction of the spinning unit, and the deterioration of the quality of the yarn wound around the package can be effectively suppressed. In addition, since the parts are replaced at the timing when the malfunction actually occurs and the trouble occurs, it is possible to replace only the minimum parts, and the cost can be reduced efficiently.

The above-described fine spinning winder management system is preferably configured as follows. That is, when the winding operation is interrupted in the middle, the management system records the unwinding length information indicating the unwinding length at the time of interruption. The management system refers to the unwinding length information of the bobbin when the rewinding operation is performed again using the bobbin in which the winding operation is interrupted. The amount of fluff is recorded in correspondence with the unwinding yarn length in consideration of

As a result, even if the bobbin whose winding operation has been interrupted is re-conveyed to the winding unit, the amount of fluff is recorded based on the unwinding yarn length taking into account the yarn length already wound. Therefore, the location where the fluff is detected can be accurately identified.

In the management system, it is preferable that the winding unit has a fluff suppressing device that is controlled on the basis of the occurrence tendency of fluff on a bobbin basis.

This makes it possible to keep the yarn quality wound up in the package more uniform because fluff is suppressed in accordance with the tendency to occur.

According to the second aspect of the present invention, there is provided a fine spinning winder to which the management system is applied.

Next, embodiments of the invention will be described. FIG. 1 is a schematic plan view showing a fine spinning winder 1 according to an embodiment of the present invention 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 (conveyance body) 50 on which the bobbin 23 is set. The tray conveyance path 90 includes the spinning machine 2 and the winder. 3 and a bobbin automatic supply device (bobbin transport mechanism) 6 are disposed. 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-like 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 management system (textile machine management system) that manages information on the bobbin 23 on the tray 50 using 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 (data recording unit) 60 in which appropriate information can be written is arranged inside the base unit 50a, and information on the bobbin 23 is stored in the RF tag 60 ( The status of the bobbin 23 is managed by writing (for each tray 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.

Next, the spinning unit 32 will be described in detail with reference to FIG. As shown in FIG. 4, the spinning unit 32 of the present embodiment is for spinning by adding twist to the sliver or roving yarn generated 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 rollers include 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 includes 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 arranged so as to face each other across the sliver or roving yarn travel path, and are configured to nip the sliver or roving yarn with a predetermined pressure. Has been. 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 sliver or the roving 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, a yarn (from which a sliver or a coarse yarn is drawn) sent from the draft mechanism 101 is used as a traveler 114 and a ring 113. The end 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 this 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 the 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 downstream 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 RF tag 60 of the tray 50 that has first passed the reading position of the RF writer 4 after simultaneous doffing is set to No. as the spindle number of the spinning unit 32 arranged on the most downstream side. 1 is memorized. The weight number of the RF tag 60 of the tray 50 conveyed next is No. No. 1 as the spindle number of the spinning unit 32 adjacent to the upstream side of the one spinning unit 32. 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.

Note that the duffing information (doffing execution time, etc.) is recorded in the RF tag 60 together with the weight number for the following reason. 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 completed, 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 (the 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 automatic bobbin supplying device 6 is provided with a mouthing device 7, and this mouthing device 7 is arranged on the actual bobbin conveying 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 base control device 11 as a control device. And comprising. In addition, the winder 3 includes a clearer control box (CCB) 12 to which a later-described clearer (fluff detection unit) 15 included in the winding unit 31 is connected.

Further, 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 a space where the bobbin 23 can be introduced is free, the bobbin 23 is introduced into the bobbin standby loop 94 and is transported 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. By controlling the tension of the wound yarn by the tension applying device 13, the quality of the package 30 can be improved.

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 for detecting a yarn defect and fluff amount by detecting the thickness of the yarn with an appropriate sensor. 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. An unillustrated rotation sensor is attached to the winding drum 24, and a rotation pulse signal is output to the unit control unit (yarn length calculation unit) 10 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 RF tag 60 of the tray 50 on which the bobbin 23 taken up by the take-up unit 31 can be read. Information read by the RF reader 5 is transmitted to the machine base control device 11.

As shown in FIG. 2, the machine base control device 11 includes a display (notification unit) 16 as a display unit and an input key 17 as an operation unit. 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.

The CCB 12 determines whether or not a yarn defect or the like has occurred based on the information transmitted from the clearer 15. As shown in FIG. 2, the CCB 12 has a display 18 as display means, and is configured to display various information such as information related to yarn defects and information generated based on yarn defects on the display 18. ing. 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.

Also, 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 23 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 end portions of the plurality of bobbin supply paths 95 are configured to join the empty bobbin transport path 96 respectively. 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 bobbin automatic supply 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 connecting the spinning machine 2 and the winder 3.

Actually, in addition to the empty bobbin, the actual bobbin or the defective bobbin is randomly mixed, and the empty bobbin conveyance path 96 is conveyed. 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 (a bobbin having a yarn remaining) is conveyed through an 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 bobbin 23 side thread end cannot be sucked and captured by the lower thread guide pipe 25, for example, when the thread end is wrapped around the bobbin 23, or when the thread breaks near the bobbin 23, etc. The yarn end cannot be captured by the lower yarn guide pipe 25, and 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 empty bobbins 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 apron belt 105 is damaged or worn, a thickness unevenness may occur in the yarn produced by the spinning unit 32. 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, in the present embodiment, as described above, the thickness and fluff of the yarn unwound from the bobbin 23 are detected by the clearer 15. In the present embodiment, when the magnitude of the yarn thickness variation and the fluff amount detected by the clearer 15 of a certain winding unit 31 exceed a predetermined allowable range, the bobbin currently being wound in the winding unit 31 is It is determined that the bobbin is defective.

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 a defective bobbin is detected in a certain winding unit 31, the machine base control device 11 is configured to store information indicating that the defective bobbin is detected in the winding unit 31. As described above, when the bobbin 23 is wound by the winding unit 31, information recorded on the RF tag 60 of the tray 50 on which the bobbin 23 is mounted (information for identifying 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 a 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.

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 as shown in FIG. 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 quality inspection function of the management system applied to the fine spinning winder 1 will be described with reference to FIG. FIG. 6 is an explanatory diagram for explaining trend data used for quality inspection. A graph of the trend data is shown on the upper side of FIG. A schematic diagram of the bobbin 23 expressing how the remaining yarn amount decreases in accordance with the unwinding yarn length of the trend data is shown on the lower side of FIG. The quality inspection function of this embodiment is a function for checking whether or not the quality of the yarn wound around the actual bobbin is maintained within a certain quality assurance range. The quality assurance range here refers to a range in which the amount of fluff wound around one bobbin is below a predetermined value over the entire yarn, and there is a possibility that the amount of fluff is out of the quality assurance range. It means that there is a possibility of becoming more. The predetermined value is set to a value smaller than the value of the fluff amount used as a reference when the clearer 15 determines that the bobbin is defective.

In this embodiment, the quality inspection is performed by comparing trend data indicating the tendency of occurrence of the fluff amount of the yarn wound around the actual bobbin in time series. As shown in FIG. 6, the trend data is data indicating the relationship between the amount of fluff and the unwinding length when the amount of fluff is detected. The unwinding yarn length here is the yarn length unwound from the actual bobbin (the yarn length wound around the package 30 from the actual bobbin). The unwinding length is calculated based on the number of rotations of the winding drum. A method for calculating the unwinding yarn length will be described later.

Information indicating the unwinding length is transmitted from the unit control unit 10 to the machine base control device 11 for each winding unit 31 and input. In addition, the CCB 12 receives information indicating the amount of fluff at an appropriate interval from the clearer 15 for each winding unit 31. The machine control device 11 and the CCB 12 exchange trend information and information indicating the fluff amount to generate trend data in units of bobbins. That is, from the start of unwinding of the bobbin 23 to the end of unwinding, the bobbin 1 is sequentially processed by associating the information indicating the fluff amount with the information indicating the unwinding length when the fluff amount is detected. The trend data for this is generated. The generated trend data is stored in the machine control device 11 in time series for each spinning unit 32 specified by the bobbin information of the RF tag 60 (by weight number).

Determination conditions are set in advance in the machine base control device 11, and it is determined by this determination condition whether there is a possibility that newly stored trend data may be out of the quality assurance range. More specifically, when the newly stored trend data is generated, the machine control device 11 compares the trend data with the past trend data, and shows a change such that the new trend data satisfies the determination condition. It is determined that there is a risk of falling outside the quality assurance range. The determination conditions are appropriately set according to the yarn count and type. In this embodiment, the operator can change the determination condition by operating the input key 17 of the machine base control device 11.

By the way, the traveler 114 included in the spinning unit 32 is a component that needs to be replaced periodically because of deterioration due to friction. When the traveler 114 is not replaced at an appropriate timing, the fluff amount may increase over the entire yarn due to the wear of the traveler 114 as shown in FIG. 6 (current trend data with respect to past trend data). Conventionally, it has been difficult to detect such a change in which the fluff gradually increases over such a long span by the clearer 15 alone. However, with the configuration of this embodiment, by setting the determination condition so as to detect a change in which the current trend data increases over the entire yarn with respect to past trend data, It is possible to detect a tendency for fluff to increase over a long span as described above.

Also, the determination condition can be set in consideration of the position of the bobbin 23 where the yarn is wound based on the unwinding yarn length. For example, as shown in FIG. 6, the fluff amount of the yarn wound around the bobbin 23 shows a relatively large value near the end of the unwinding operation of the bobbin 23. Considering this, for example, when the amount of fluff increases rapidly at the timing near the end of the unraveling operation, it is determined to determine that there is a risk that it will fall out of the quality assurance range even if the amount of change in other parts is small It is also possible to set conditions.

When the newly generated trend data changes so as to satisfy the determination condition, the machine control device 11 displays information (for example, the above-described spindle number) that can identify the spinning unit 32 requiring maintenance on the display 16. indicate. This display can also be performed on the display 18 of the CCB 12. Further, the machine control device 11 of the present embodiment is configured so that the trend data stored in the machine control device 11 can be displayed on the display 16 for each spinning unit 32, for example, in a graph format. . With this configuration, the operator can intuitively grasp the change in the tendency of fluff generation through vision.

The trend data generation process and storage process are performed by a quality inspection unit provided in the winder 3. As the quality inspection unit, either the machine control device 11 or the CCB 12 functions. In addition, the structure of a quality inspection part can be suitably changed according to a situation.

Next, a method for calculating the unwinding length will be described. As described above, the rotation pulse signal is input to the unit controller 10 from the rotation sensor attached to the winding drum 24 (see FIG. 5). The unit controller 10 counts the rotation pulse signal and calculates the unwinding length based on the count value. This count value is reset at the timing when a new actual bobbin that has not yet been wound up is conveyed or when all the yarn is unwound from the actual bobbin, and at the timing when the yarn of the new actual bobbin is unwound. Counting starts based on this. In the present embodiment, the yarn length wound around the bobbin 23 by the spinning unit 32 is stored in advance as a preset yarn length, and this information is used for various determination processes.

Next, calculation of the unwinding length when the winding operation is interrupted will be described. As described above, the bobbin 23 in which the yarn breakage or the like has occurred during the winding operation and the suction and capture by the lower yarn guide pipe 25 cannot be performed is once discharged from the winding position to the empty bobbin conveyance path 96. At this time, the machine control device 11 stores unwinding length information indicating the unwinding length when the winding operation is stopped in association with the bobbin information of the bobbin 23 that has been unwinding.

When the machine base control device 11 acquires the bobbin information of the bobbin 23 that has been newly conveyed to the winding unit 31, the machine base control device 11 refers to the stored bobbin information to determine whether the bobbin has been interrupted in the winding operation. Determine whether. In the case of the bobbin 23 in which the winding operation is interrupted, the unwinding length information stored in association with the bobbin 23 is referred to. Then, a value obtained based on the unwinding length information is added to the count value to calculate the unwinding length. Since the unwinding yarn length calculated in this way takes into account the already wound yarn length, it is almost the same as the actual unwinding length from the bobbin 23, and the trend data is accurate. Can be generated.

With the above configuration, the bobbin 23 around which the yarn spun by the fine spinning unit 32 is wound is unwound by the winding unit 31, and trend data is generated at the same time. The generated trend data is distinguished by the spindle number of each spinning unit specified based on the bobbin information stored in the RF tag 60 and stored in time series. If the newly generated trend data is changed to satisfy the determination result as a result of comparison with the past trend data of the same spinning unit 32, the machine control device 11 determines that the quality of the actual bobbin is It is determined that there is a risk of falling outside the quality assurance range. Then, information specifying the spinning unit 32 that has produced the actual bobbin that may fall out of the quality assurance range is displayed on the display 16 of the machine control device 11, and the operator is informed that the spinning unit 32 needs to be maintained. To inform.

As described above, the spinning winder 1 of the present embodiment includes the spinning machine 2, the winder 3, and the bobbin automatic supply device 6. The spinning machine 2 includes a plurality of spinning units 32 that wind the spun yarn around the bobbin 23. The winder 3 includes a plurality of winding units 31 that unwind the yarn wound around the bobbin 23 to form the package 30. The bobbin automatic supply device 6 conveys the tray 50 on which the bobbin 23 around which the yarn is wound by the spinning machine 2 is set to the winding unit 31. The tray 50 includes an RF tag 60 capable of recording information for specifying the spinning unit 32 that winds the yarn around the bobbin 23 set in the tray 50. The winding unit 31 includes a clearer 15, a unit control unit 10, and an RF reader 5. The clearer 15 is for detecting the amount of yarn fluff. The unit controller 10 is for calculating the unwinding yarn length indicating the length of the unwinding yarn from the bobbin 23. The RF reader 5 is for reading information of the RF tag 60 of the bobbin 23 on which the winding operation is performed. The winder 3 records the fluff amount together with the length of the unwound yarn when the clearer 15 detects the fluff amount, and a quality inspection unit that performs the quality inspection of the yarn spun by the spinning unit 32 in units of the bobbin 23. (Machine control device 11 or CCB 12).

Thereby, since the spinning unit 32 that has spun can be specified based on the information of the RF tag 60, the quality of the yarn produced by the spinning unit 32 can be inspected in units of 23 bobbins. In addition, since quality inspection can be automatically performed on the production line in parallel with the winding operation, the work of quality inspection can be saved. In addition, since the amount of fluff is recorded in correspondence with the yarn length, it is possible to accurately grasp the tendency of fluff generation indicating which portion of the yarn is fluffy, and to detect and deal with fluff. It becomes possible to carry out efficiently.

In the fine spinning winder 1 of this embodiment, the fine spinning unit 32 is configured as a ring spinning unit having a traveler 114.

Thereby, since the fluff generation tendency can be accurately grasped in units of the bobbin 23, an increase in the fluff amount of the entire yarn caused by the deterioration of the traveler 114 due to wear can be easily detected.

Further, the fine spinning winder 1 of the present embodiment is configured as follows. That is, the spinning winder 1 includes a display 16 of the machine base control device 11, and the display 16 is configured to be able to notify the spinning unit 32 that is identified as requiring maintenance. Then, the management system monitors the occurrence tendency of the fluff of the yarn produced by the same spinning unit 32 in units of the bobbin 23, and the change tendency so that the occurrence tendency of the fluff satisfies the determination condition from the past occurrence tendency of the fluff. Is displayed, information specifying the spinning unit 32 is displayed on the display 16 to notify the operator.

As a result, by monitoring the change in the fluff generation tendency in units of the bobbin 23, it is possible to detect the change in the amount of fluff caused by the malfunction of the spinning unit 32 that occurs during the operation of the system in units of the bobbin, thus requiring maintenance. It is possible to inform the operator of the spinning unit 32 having the characteristics. Therefore, the operator can quickly cope with the malfunction of the spinning unit 32, and the deterioration of the quality of the yarn wound around the package can be effectively suppressed. In addition, since the parts are replaced at the timing when the malfunction actually occurs and the trouble occurs, it is possible to replace only the minimum parts, and the cost can be reduced efficiently. Further, by analyzing the fluff generation tendency (trend data) of each spinning unit 32, it is also possible to grasp the simultaneous replacement time of the traveler 114.

Moreover, the management system applied to the fine spinning winder 1 of this embodiment is configured as follows. That is, when the winding operation is interrupted in the middle, the management system records the unwinding length information indicating the unwinding length at the time of interruption. The management system refers to the unwinding length information of the bobbin 23 when the winding operation is performed again using the bobbin 23 in which the winding operation is interrupted. The amount of fluff is recorded in correspondence with the unwinding length considering the information.

As a result, even if the bobbin 23 in which the winding operation is interrupted is re-conveyed to the winding unit 31, the amount of fluff is recorded based on the unwinding yarn length in consideration of the already wound yarn length. Therefore, it is possible to accurately identify the location where the fluff is detected.

Although the fine spinning winder 1 according to the embodiment of the present invention has been described above, the configuration of the fine spinning winder 1 can be appropriately changed according to circumstances as long as the management system of the present invention is applied. For example, the winding unit 31 of the winder 3 can be changed to a configuration including a fluff suppressing device. Next, a modification in which the winding unit 231 includes the fluff suppressing device 201 will be described with reference to FIG. FIG. 7 is a side view illustrating a configuration of a winding unit 231 according to a modification. In addition, since the modified example demonstrated below is the same as that of the said embodiment except the point which a winding unit equips with a fluff suppression apparatus, the description is abbreviate | omitted.

As shown in FIG. 7, the winding unit 231 includes a fluff suppressing device 201 above the tension applying device 13 (on the downstream side in the yarn traveling direction). The fluff suppressing device 201 of this modification has a swirl flow generating means (not shown in the drawing) for generating a swirl flow, and suppresses fluff by the swirl flow generated by the swirl flow generating means. As shown in FIG. 7, the yarn unwound from the bobbin 23 passes through this swirling flow and is wound around the package 30.

The fluff suppressing device 201 of the present modification is configured to be able to adjust the flow rate of the swirling flow and to be able to adjust the timing for generating the swirling flow. And the fluff suppression apparatus 201 is controlled so that a swirl | vortex flow acts according to trend data. That is, the strength of the swirling flow generated in the fluff suppressing device 201 changes based on the trend data, and control is performed to increase the fluff suppressing action in a portion where the amount of fluff is large. In addition, the control method of the fluff suppression apparatus 201 can be appropriately changed according to circumstances. For example, considering that the amount of fluff increases immediately before unwinding progresses and the remaining yarn amount becomes zero, the fluff suppressing device 201 can be controlled to operate in accordance with such timing. .

As described above, in the management system of the modified example, the winding unit 231 is configured to include the fluff suppressing device 201 that is controlled based on the fluff generation tendency of the bobbin 23 unit.

Thereby, fluff is suppressed according to the tendency to occur, so that the quality of the yarn wound around the package 30 can be kept more uniform.

Although the embodiment of the present invention has been described above, the above configuration can be further modified as follows.

In the above embodiment, 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.

Further, when the winding unit 31 of the above embodiment further includes an RF writer (data writing unit) and the winding operation is interrupted, the unwinding length of the RF tag 60 is reduced by the RF writer. It can also be configured to store information. In this case, the RF tag 60 of the tray 50 that has been transported is read by the RF reader 5 and the unwinding length is calculated while referring to the stored unwinding length information.

Also, the notification means for notifying the operator that maintenance is necessary can be changed as appropriate. For example, a warning light is arranged as a notification means for each spinning unit 32, and when it is determined that maintenance is necessary by the quality inspection function, the warning light is operated (lit) to notify the operator. You can also.

Further, in the above modification, a device using a swirling flow is adopted as the fluff suppressing device, but this configuration can be appropriately changed according to circumstances. For example, it is possible to employ a fluff suppressing device configured to perform fluffing treatment by applying false twist to the spun yarn traveling between the disks by rotating a plurality of friction disks and winding the fluff into the fibers.
