The yarn Y2 is guided to the yarn joining device 51. The yarn joining device 51 connects the yarn end portion of the lower yarn Y1 guided by the lower yarn catching guide member 53 with the yarn end portion of the upper yarn Y2 guided by the upper yarn catching guide member 54. Thread Y

  The yarn clearer 52 always obtains information on the thickness of the traveling yarn Y, and based on the information on the yarn thickness, an abnormal portion included in the yarn Y that is thicker than a certain thickness is regarded as a yarn defect. To detect. The yarn clearer 52 is provided with a cutter 52a. When a yarn defect is detected by the yarn clearer 52, the cutter 52a immediately cuts the yarn Y. The yarn clearer 52 monitors the running state of the yarn Y, and outputs a signal indicating the absence of yarn to the unit control unit 63 when detecting that the yarn Y is not running.

  When the yarn Y does not travel from the yarn supplying unit 31 to the winding unit 33 due to occurrence of yarn breakage or the like, this state is detected by the yarn clearer 52, and the yarn joining operation by the yarn joining device 51 is performed. Done. When the package P is being wound, or when the yarn is cut by the cutter 52a of the yarn clearer 52, the lower thread Y1 is captured by the suction portion 60 of the lower thread capturing guide member 53. Is detected by the yarn feeler 49. On the other hand, when all the yarn Y is unwound from the yarn supplying bobbin 8 and the yarn Y disappears, the yarn feeler 49 does not detect the lower yarn Y1. That is, when it is detected by the yarn clearer 52 that the yarn Y is not running, the unit control unit 63 determines whether the yarn feeler 49 detects the yarn, or breaks the yarn, and the yarn feeding bobbin 8. A state in which all the yarns Y are unwound and recognized.

  The unit control unit 63 shown in FIG. 5 controls the operation of each part of the winding unit 4 such as the winding unit 33 and the yarn joining device 51 described above to form the package P on the winding tube 44. . The unit control unit 63 includes a CPU (Central Processing Unit) that is an arithmetic processing unit, a ROM (Read-Only Memory) in which a program executed by the CPU and data used in the program are stored, and data when the program is executed. RAM (Random Access Memory) for temporarily storing data, an input / output interface for inputting / outputting data to / from the outside, and the like.

  The unit control unit 63 includes a drive unit for the winding unit 4 such as a motor 39 for driving the tray supply / discharge unit 34, a motor 42 for the unwinding assisting device 36, and a drum drive motor 47, a yarn feeler 49, and a tension applying device 50. Are electrically connected to the yarn joining device 51, the yarn clearer 52, the yarn layer sensor 41, the reading / writing device 35 and the like. And the winding unit 4 controls each part of the winding unit 4 based on the information about the winding conditions and the like sent from the machine control device 5 that controls the overall operation of the automatic winder 1, and the winding unit 4 4 causes the package P to be wound.

(Machine control device 5)
As shown in FIG. 2, the machine base control device 5 can communicate with the control unit 13 of the bobbin preparation device 2, the control unit 21 of the tray transport device 3, and the unit control units 63 of the plurality of winding units 4. And controls the operations of the bobbin preparation device 2, the tray transport device 3, and the plurality of winding units 4. In addition, the machine base control device 5 includes an input unit 70, a display unit 71, and a lamp 72. The input unit 70 is configured to be able to input various conditions necessary for controlling each device of the automatic winder 1. The display unit 71 can display a display of the operating status of each device of the automatic winder 1 or a display regarding an abnormality of each device. The lamp 72 is lit to notify the operator of the occurrence of an abnormality when any abnormality occurs in each device of the automatic winder 1.

  By the way, in the automatic winder 1 described above, when an abnormality occurs in the tray main body member 22 of the tray 7 conveyed by the tray conveying device 3, it is expected that various problems occur. In the present embodiment, as a specific example of the above problem, a case where the yarn feeding bobbin 8 is inclined with respect to the upright state will be described. FIG. 6 is a view showing a state where the yarn feeding bobbin 8 is inclined due to the abnormality of the tray main body member 22 of the tray 7.

  As described above, the tray body member 22 of the tray 7 of the present embodiment has a plurality of (for example, three) holding claws 28 for holding the yarn feeding bobbin 8 in the peg portion 25, Each of these holding claws 28 is urged outward by a spring member. Here, if some of the spring members are damaged and the holding claws 28 cannot be urged outward, the holding claws 28 cannot be pressed against the inner surface of the yarn feeding bobbin 8. FIG. 6 shows a state where the spring member of the left holding claw 28 is broken. Due to the breakage of the spring member, the pressing force to the yarn supplying bobbin 8 differs among the plurality of holding claws 28, and the yarn supplying bobbin 8 is held in an inclined state with respect to the upright state of FIG. End up. When the yarn Y is unwound in the winding unit 4 with the yarn feeding bobbin 8 tilted, the balloon of the unwound yarn Y becomes unstable and the tension of the yarn Y is not stable. Moreover, the cylinder 40 and the yarn layer of the yarn supplying bobbin 8 may come into contact with each other.

  FIG. 7 is a view for explaining the inclination of the yarn supplying bobbin 8. FIG. 7A shows a state where the yarn feeding bobbin 8 in an upright state is supplied to the yarn feeding unit 31. As shown in FIG. 7A, when the yarn supplying bobbin 8 is in the upright state, the axis C2 of the yarn supplying bobbin 8 is coincident with the axis C1 of the cylindrical body 40. On the other hand, FIG. 7B shows a state in which the yarn supplying bobbin 8 tilted with respect to the upright state is supplied to the yarn supplying unit 31. As shown in FIG. 7B, when the yarn supplying bobbin 8 is inclined with respect to the upright state, the axis C2 of the yarn supplying bobbin 8 is inclined with respect to the axis C1 of the cylindrical body 40. In the state of FIG. 7B, the upper end portion of the yarn supplying bobbin 8 is displaced from the axis C1 of the cylindrical body 40. Therefore, when the yarn Y is unwound from the yarn supplying bobbin 8 in this state, the yarn supplying Since the core tube of the bobbin 8 comes into contact with the cylindrical body 40 and the unwinding of the yarn Y is blocked by the contact between the core tube of the yarn supplying bobbin 8 and the cylindrical body 40, the yarn Y is broken.

  Note that the winding unit 4 (tray feeding / discharging portion 34) of the present embodiment has a centering function for matching the position of the upper end portion of the yarn feeding bobbin 8 for unwinding the yarn Y with the axis C1 of the cylindrical body 40. Have. More specifically, the tray feeding / discharging unit 34 moves the tray 7 in the horizontal direction so that the yarn layer of the yarn feeding bobbin 8 falls within the range detected by the yarn layer sensor 41. Adjust the position. After this centering, unwinding of the yarn Y from the yarn supplying bobbin 8 and winding of the package P are started.

  However, when the yarn feeding bobbin 8 is inclined, even if the upper end of the yarn feeding bobbin 8 is made to coincide with the axis C1 of the cylindrical body 40 by the above-described centering before starting winding, the yarn feeding bobbin 8 Thread breakage due to the inclination of the thread may occur. That is, when the yarn supplying bobbin 8 is inclined, the yarn layer is lowered in accordance with the unwinding of the yarn Y, so that the core tube of the yarn supplying bobbin 8 or the chess portion 8a of the yarn layer is formed in the cylindrical body 40. May come into contact.

  By the way, just because the yarn feeding bobbin 8 is inclined does not always mean that an abnormality has occurred in the tray body member 22. That is, the inclination of the yarn feeding bobbin 8 may occur even when the tray 7 is normal and the yarn feeding bobbin 8 is not installed correctly by the bobbin mounting unit 11 of the bobbin preparation device 2. Further, when there is a problem on the yarn feeding unit 31 side of the winding unit 4, for example, when there is an abnormality such as tilt or breakage in the cylinder 40 of the unwinding assisting device 36, the core tube of the yarn feeding bobbin 8 or The chess portion 8a may come into contact with the cylindrical body 40 and thread breakage may occur. Therefore, in this embodiment, when the yarn breakage after the centering operation of the yarn feeding bobbin 8 is detected for the same tray 7 many times, the tray main body member 22 of the tray 7 is abnormal. Is determined to have occurred.

  FIG. 8 is a flowchart of the tray abnormality detection process. In FIG. 8, Si (i = 1, 2, 3,...) Indicates a step number. In the present embodiment, the processing of FIG. 8 is mainly performed by the unit control unit 63 of each winding unit 4. When the tray 7 loaded with the yarn feeding bobbin 8 is supplied by the tray supply / discharge unit 34, the unit control unit 63 controls each part of the winding unit 4 to start winding the package P (S1).

  If a yarn breakage occurs in the wound yarn Y in the winding unit 4 during winding of the package P, the yarn breaker 52 detects the yarn breakage. In addition, after the yarn breakage occurs, the yarn joining is performed by the yarn joining device 51. However, the yarn feeding bobbin 8 is tilted and the core tube of the yarn feeding bobbin 8 comes into contact with the cylindrical body 40. Even when yarn joining is performed, the same yarn breakage occurs immediately. Therefore, it is determined whether or not the yarn breakage is caused by the inclination of the yarn feeding bobbin 8 based on whether or not the yarn breakage occurs continuously a plurality of times.

  That is, as shown in FIG. 8, even if a yarn breakage occurs in the yarn Y that unwinds the yarn Y from the yarn supply bobbin 8, if the yarn breakage number M detected by the yarn clearer 52 is less than M0 ( (S2: No), the unit controller 8 causes the yarn joining device 52 to perform yarn joining and continues winding the package P. If all the yarns Y of the yarn feeding bobbin 8 are unwound before the yarn breakage number M reaches M0 (S3: Yes), the unit control unit 63 controls the tray supply / discharge unit 34 to control the tray 7 Is discharged (S7). Note that the number of thread breaks M in the flowchart of FIG. 8 does not include the number of forced thread cuts by the cutter 52a of the yarn clearer 52. In this way, the tray 7 (7B) on which the empty bobbin 8B is mounted, in which the yarn Y is normally unwound, is transported by the collection path 14b of the tray transport device 3 and sent to the bobbin preparation device 2.

  On the other hand, when the number M of thread breaks detected by the yarn clearer 52 is equal to or greater than M0 (S2: Yes), the unit controller 63 indicates that the thread break is a thread break due to the inclination of the yarn feeding bobbin 8. And the reading / writing device 35 is controlled to read the tray information stored in the IC tag 26 of the tray 7 (S4). The tray information includes a tray number. Based on the tray number, the unit control unit 63 identifies the tray 7 on which the yarn feeding bobbin 8 in which a malfunction has occurred is mounted. If a yarn break due to the inclination of the yarn feeding bobbin 8 has been detected even once before this, the past defect information is stored in the IC tag 26 as described later in S6. Yes. In this case, at S4, the reading / writing device 35 reads out the defect information simultaneously with the tray number.

  If the occurrence number N of the failure is less than a certain determination threshold N0 due to the occurrence of the failure this time (S5: Yes), the number of occurrences of the failure is still small. It is not determined that the main body member 22 is abnormal. However, the defect information is written to the IC tag 26 of the tray 7 in the reading / writing device 35 (S6). Further, the unit control unit 63 controls the tray supply / discharge unit 34 to discharge the tray 7 without causing the winding unit 33 to wind the package P any more (S7).

  After the tray 7 in which the trouble has occurred in the winding unit 4 is discharged to the collection path 14b, the bobbin preparation device 2 again extracts the yarn feeding bobbin 8 and remounts it, and then returns to the supply path 14a. It is returned and supplied to the winding unit 4 again. If the yarn supplying bobbin 8 is tilted due to the defective attachment of the yarn supplying bobbin 8 to the tray 7, the yarn supplying bobbin 8 can be corrected to the upright state by the above reattachment. However, when the yarn feeding bobbin 8 is tilted due to an abnormality in the tray body member 22 of the tray 7, the yarn feeding bobbin 8 is still tilted even if the above-described remounting is performed. If such an abnormal tray 7 is left unattended, the abnormal tray 7 is supplied to the take-up unit 4 and the yarn feed bobbin 8 tilts and the yarn Y breaks each time. For this reason, the abnormal tray 7 is circulated in the tray conveyance device 3.

  Therefore, when a yarn breakage failure due to the inclination of the yarn feeding bobbin 8 is detected in the winding unit 4, the failure occurrence frequency N is greater than or equal to the determination threshold N0 due to this failure (S5: Yes). The unit controller 63 determines that an abnormality has occurred in the tray body member 22 of the tray 7. In this case, the tray 7 is discharged by controlling the tray supply / discharge unit 34 without writing any defect information on the IC tag 26 (S8). In the present embodiment, the unit control unit 63 of each winding unit 4 corresponds to a “tray abnormality detection unit” of the present invention in which an abnormality relating to the tray body member 22 of the tray 7 is detected (determined).

  Note that the “number N of occurrences of defects” in S5 may be the number of occurrences within the limited determination time T0. In this case, every time the inclination of the yarn feeding bobbin 8 is detected, the unit controller 63 causes the reading / writing device 35 to store the occurrence time of the failure in the IC tag 26 as failure information. The number of defect information (failure history) stored in the IC tag 26 is, for example, about five. Then, if N0 times of trouble occurs within the determination time T0, it is determined that an abnormality has occurred in the tray body member 22 of the tray 7.

  The determination threshold value N0 or the determination time T0 can be input by the input unit 70 of the machine control device 5. As described above, the determination condition for determining whether or not an abnormality has occurred in the tray main body member 22 is optimally set according to various conditions such as the type of the yarn feeding bobbin 8 and the type of the tray 7. Can do.

  Alternatively, the “number of occurrences of defects N” in S5 may be a cumulative value of the number of occurrences of defects since the use of the tray 7 is started (the total number of occurrences of defects so far).

  When it is determined that an abnormality has occurred in the tray main body member 22, the unit control unit 63 controls the tray supply / discharge unit 34 to discharge the tray 7. Further, as described above, the unit control unit 63 recognizes which tray 7 is determined to be abnormal by the tray number read from the IC tag 26 in S3. Therefore, the unit control unit 63 transmits the information regarding the tray number of the tray 7 and the defect content to the machine base control device 5. The machine control device 5 receives the signal transmitted from the unit controller 63 and controls the tray transport device 3 to transport the tray 7C determined to be abnormal from the recovery path 14b to the branch recovery path 16, and further to branch. Stop at the abnormal tray stop position Ps provided in the collection path 16 (S9).

  The unit control unit 63 transmits an alarm signal to the machine base control device 5 (S10). This alarm signal may be a signal for turning on the lamp 72 of the machine base control device 5, for example. Alternatively, the alarm signal may be a signal that causes the display unit 71 of the machine control device 5 to display information regarding the abnormal tray 7C. In addition, a signal for operating other notification means such as a buzzer (not shown) may be used.

  When the operator notices an abnormality in the tray 7 by turning on the lamp 72 or displaying the abnormal tray 7 on the display unit 71, the operator selects the abnormal tray 7 </ b> C stopped at the abnormal tray stop position Ps of the branch collection path 16. Remove and replace with a new tray 7. As shown in FIG. 3, since the notch 18a is provided in the portion of the guide rail 18 where the abnormal tray stop position Ps is set, the abnormal tray 7C fitted to the guide rail 18 is It becomes easy to remove from the guide rail 18 at the notch 18a. Further, since the tray storage portion 16a is provided on the downstream side of the branch collection path 16 with respect to the conveyance direction from the abnormal tray stop position Ps, even if the operator cannot immediately discharge the abnormal tray 7C, there are plural The abnormal tray 7C can be stored in the tray storage portion 16a.

  The notification to the operator by the lamp 72 or the like may be performed after the abnormal tray 7C has stopped at the abnormal tray stop position Ps so that the operator can immediately recognize which tray 7 is abnormal.

  When the abnormal tray 7C stops at the abnormal tray stop position Ps, the stop is detected by the abnormal tray detection sensor 29 (see FIG. 3) of the tray transport device 3. In addition, for example, when the unit controller 63 receives a signal indicating that the abnormal tray 7 </ b> C has stopped at the abnormal tray stop position Ps from the machine base control device 5, the alarm signal is sent to the machine control device 5. May be sent to. Alternatively, the unit control unit 63 may simultaneously transmit an alarm signal to the machine base control device 5 together with the tray number of the abnormal tray 7C. In that case, the machine control device 5 first controls the tray transport device 3 to stop the abnormal tray 7C at the abnormal tray stop position Ps, and then uses the lamp 72 or the display unit 71 based on the alarm signal. Notification.

  Alternatively, contrary to the above, the abnormal tray 7 may be configured to stop at the abnormal tray stop position Ps after the operator is notified first. In that case, the stop of the abnormal tray 7C in S9 in FIG. 8 and the alarm in S10 are in the reverse order. That is, first, after an alarm signal is issued from the unit control unit 63 and a notification is given to the operator by turning on the lamp 72 or the like, the machine control device 5 controls the tray transport device 3 to detect the abnormal tray 7. Is stopped at the abnormal tray stop position Ps. In this case, since the abnormal tray 7 is ejected from the winding unit 4 and conveyed toward the abnormal tray stop position Ps while the operator is notified by the lamp 72 or the like and heads toward the abnormal tray stop position Ps, the operator When the tray reaches the abnormal tray stop position Ps, the tray 7 can be replaced immediately, and an efficient work can be performed.

  As described above, in this embodiment, when an abnormality occurs in the tray body member 22 of the tray 7 on which the yarn feeding bobbin 8 is placed, the abnormality is detected by the unit control unit 63. Therefore, even when a malfunction such as the yarn feeding bobbin 8 tilting and the yarn Y cannot be unwound due to the abnormality of the tray main body member 22, the operator can quickly grasp the abnormality of the tray 7. By replacing the abnormal tray 7C with another tray 7, the above problem can be solved at an early stage.

  The tray 7 has an IC tag 26 that stores tray information including a tray number (identification information of the tray 7), defect information, and the like. Therefore, when the unit control unit 63 detects an abnormality in the tray body member 22 of a certain tray 7, the tray 7 in which the abnormality has occurred can be identified. By specifying the abnormal tray 7C, the abnormal tray 7C can be stopped at the abnormal tray stop position Ps at a position away from the winding unit 4 and exchanged by the operator. Further, since the above-mentioned tray information can be stored in the IC tag 26 of the tray 7 in a rewritable manner by the reading / writing device 35 of the winding unit 4, the failure information is stored in the IC tag every time a failure occurs. 26 can be stored. Furthermore, since the tray 7 has the IC tag 26 that stores the tray information, it is not necessary to provide a storage unit that stores the tray information in another device, for example, the unit control unit 63 of the winding unit 4.

  Further, in the present embodiment, when a failure caused by the tray main body member 22 occurs, it is not determined that the tray main body member 22 is abnormal by only one occurrence of the failure, and the failure information is temporarily stored in the IC tag 26. Just remember it. Then, after referring to the defect information stored in the IC tag 26 for the tray 7 in the past, the same tray 7 is not used until the same defect has occurred many times. It is determined that an abnormality has occurred in the main body member 22. Therefore, although the tray body member 22 is normal, it is less likely that the tray body member 22 is erroneously determined to be abnormal, and the determination accuracy is improved.

  In the present embodiment, when an abnormality of the tray 7 is detected by the unit control unit 63 of each winding unit 4, the lamp 72 of the machine base control device 5 is turned on, or information on the abnormal tray 7 is displayed on the display unit 71. Is displayed, the operator can easily recognize the abnormality of the tray 7. This can prompt the operator to replace the abnormal tray 7C.

  In the present embodiment, the tray 7C determined to be abnormal by the unit control unit 63 stops at the abnormal tray stop position Ps. Therefore, an operator who has recognized that an abnormality has occurred in a certain tray 7C can easily recognize which tray 7C has been determined to be abnormal by lighting the lamp 72 or the like. The abnormal tray stop position Ps is provided in the branch collection path 16 branched from the main transport path 14. For this reason, even if the abnormal tray 7C is stopped at the abnormal tray stop position Ps, the transport of the other trays 7 in the main transport path 14 is hardly hindered. Note that the reading / writing device 35 that reads tray information from the IC tag 26 of the tray 7 is located on the upstream side of the conveyance path of the tray conveying device 3 with respect to the abnormal tray stop position Ps. The tray 7C determined to be abnormal based on the information read by the device 35 can be reliably stopped at the abnormal tray stop position Ps.

  Further, in the present embodiment, the abnormal tray stop position Ps is located in the portion on the bobbin preparation device 2 side of the collection path 14b of the tray transport device 3 (portion downstream from the portion connected to the plurality of winding units 4). Is provided. Therefore, the stop of the abnormal tray 7 does not cause the tray 7 to stay (congestion) on the plurality of winding units 4 side, and the package P forming operation in the winding unit 4 is hardly hindered.

  Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.

A] In the embodiment described above, the unit control unit 63 of each winding unit 4 determines (specifies) the tray 7 in which the tray main body member 22 is abnormal, but other devices than the unit control unit 63 include An abnormal tray 7 determination function may be provided.

(Modification 1)
In FIG. 9 of the first modified example, the reading device 80 is disposed at a position upstream of the branching path of the recovery path 14b of the main transport path 14 with respect to the branch recovery path 16 in the transport direction. The reading device 80 reads tray information from the IC tag 26 of the tray 7 conveyed in the collection path 14b.

  In each winding unit 4, a point where a defect in the tilt of the yarn feeding bobbin 8 due to an abnormality in the tray main body member 22 of the tray 7 is detected and a point where the defect information is stored in the IC tag 26 of the tray 7 are as follows. This is the same as the previous embodiment. Thereafter, the reading device 80 reads the tray number of the tray 7 and the defect information from the IC tag 26 of the tray 7 flowing through the collection path 14b. Further, the reader 80 is accompanied by a determination unit 81. The determination unit 81 refers to the defect information read by the reading device 80 and determines whether or not an abnormality has occurred in the tray body member 22 of the tray 7. That is, in the first modification, the determination unit 81 associated with the reading device 80 corresponds to the “tray abnormality detection unit” of the present invention.

  The determination unit 81 transmits information such as the tray number of the tray 7 determined to be abnormal to the machine control device 5. The machine control device 5 receives the signal from the determination unit 81 and controls the tray conveying device 3 to stop the abnormal tray 7C at the abnormal tray stop position Ps provided in the branch collection path 16. Even in the first modification, the reading device 80 that reads the tray information from the IC tag 26 of the tray 7 is located on the upstream side of the conveyance path of the tray conveyance device 3 from the abnormal tray stop position Ps. The tray 7C determined to be abnormal based on the information read by the reading device 80 can be reliably stopped at the abnormal tray stop position Ps.

(Modification 2)
The machine control device 5 may determine whether the tray 7 is abnormal. For example, in FIG. 9 of the first modification, the tray information read by the reading device 80 is sent to the machine base control device 5, and the machine base control device 5 refers to the tray information and the tray main body of the tray 7. It may be determined whether or not an abnormality has occurred in the member 22.

B] (Modification 3)
When a problem with the inclination of the yarn feeding bobbin 8 occurs in a certain winding unit 4, not the abnormality of the tray body member 22, but the abnormality on the winding unit 4 side (for example, the mounting accuracy of the yarn layer sensor 41 is poor, Of course, it may be caused by misunderstanding. However, when the tray 7 that has been discharged once the defect of the yarn feeding bobbin 8 is detected is supplied to the same winding unit 4 again, the winding unit 4 has no abnormality in the tray 7. It is conceivable that a defect occurs again due to an abnormality on the side, and the defect information is written in the IC tag 26. Therefore, the defect information stored in the IC tag 26 may include the number of the winding unit 4. In this case, if a failure has occurred a plurality of times in the same winding unit 4, it is assumed that the failure is caused by an abnormality on the winding unit 4 side, and is used for determining an abnormality of the tray body member 22. It is possible to not.

C] (Modification 4)
In the above-described embodiment, it is determined that an abnormality has occurred in the tray main body member 22 when a defect due to the abnormality in the tray main body member 22 has occurred for a certain number of times. On the other hand, if a problem occurs even once, it may be determined that an abnormality has occurred in the tray body member 22 of the tray 7 at that time.

  For example, taking the configuration of the above embodiment as an example, when the inclination of the yarn feeding bobbin 8 is detected in each winding unit 4, the unit controller 63 attaches the yarn feeding bobbin 8 at that time. It is determined that an abnormality has occurred in the tray main body member 22 of the tray 7 being discharged, and the sheet is discharged from the winding unit 4 as it is. Furthermore, the unit control unit 63 transmits the tray number of the tray 7C determined to be abnormal to the machine base control device 5, and the machine base control device 5 stops the tray 7C at the abnormal tray stop position Ps.

D] In the above-described embodiment, the winding unit 4 detects the yarn breakage that occurs when the yarn feeding bobbin 8 is tilted. However, the winding unit 4 detects that the yarn feeding bobbin 8 is tilted. A possible configuration may be used.

(Modification 5)
For example, a state where the yarn feeding bobbin 8 is tilted may be detected using the yarn layer sensor 41 of the unwinding assisting device 36. In FIG. 7A shown in the embodiment, the upright yarn feeding bobbin 8 is shown. When the yarn feeding bobbin 8 is in an upright state, the yarn feeding bobbin 8 is held in the holding position A in FIG. In the state), the yarn layer sensor 41 does not detect the chess portion 8a at the upper end portion of the yarn feeding bobbin 8.

  On the other hand, FIG. 7B shows the yarn feeding bobbin 8 inclined with respect to the upright state. When the yarn supplying bobbin 8 is tilted with respect to the upright state, the yarn feeding bobbin 8 is already checked by the yarn layer sensor 41 in the state immediately after the yarn supplying bobbin 8 is held at the holding position A by the tray supply / discharge unit 34. The part 8a is detected. That is, whether or not the chess portion 8a is detected by the yarn layer sensor 41 when the yarn supplying bobbin 8 that has been placed on the tray 7 and supplied to the yarn supplying portion 31 is held at the holding position A in FIG. Thus, the unit controller 63 can grasp whether the yarn feeding bobbin 8 is inclined with respect to the upright state.

  Further, a dedicated sensor may be provided to detect the inclination of the yarn feeding bobbin 8. In this case, the dedicated sensor is not limited to an optical sensor, and various sensors such as a contact sensor and a magnetic sensor can be employed.

E] In the above-described embodiment, the problem due to the inclination of the yarn feeding bobbin 8 is cited as a problem caused by the abnormality of the tray body member 22 of the tray 7, but other problems may occur.

(Modification 6)
If the bottom surface or side surface of the tray main body member 22 is damaged or abnormal wear occurs locally, when the tray 7 is drawn into the tray passage 38 of the winding unit 4, the tray 7 It is conceivable that it will become difficult to move due to being caught in 38. In particular, in the configuration in which the supplied tray 7 is moved and the yarn feeding bobbin 8 is centered as in the above embodiment, if the tray 7 is difficult to move in the tray passage 38, the centering may not be performed. is there. In addition, if the yarn is unwound without accurate centering, the frequency of yarn breakage will increase. Therefore, the unit control unit 63 of each winding unit 4 detects whether or not the tray main body member 22 is abnormal by detecting whether or not the above-described feeding failure (movement failure) has occurred in each tray 7. It may be detected (determined).

  Incidentally, the feeding failure of the tray 7 in the tray passage 38 can be detected as follows. For example, when the tray 7 is caught in the tray passage 38, a situation may occur in which the tray 7 is moved only after the tray supply / discharge unit 34 is repeatedly driven several times. Accordingly, the feeding failure of the tray 7 may be determined based on the retry count of the feeding of the tray 7 by the tray feeding / discharging unit 34. Further, a sensor for confirming the operation of the tray supply / discharge section 34 may be provided, and the tray feeding failure may be detected by this sensor. Alternatively, the state of the tray 7 may be photographed by a camera installed in the vicinity of the tray feeding / discharging unit 34, and it may be determined from the photographed image (or moving image) whether the tray 7 is being sent normally.

(Modification 7)
In relation to the above modified embodiment 6, it is also conceivable that the tray 7 is caught not only on the tray passage 38 of the winding unit 4 but also on the guide rail 18 of the tray transport device 3 and becomes difficult to move. In that case, the conveyance failure of the tray 7 in the tray conveyance device 3 is detected using sensors, cameras, and the like installed in various places of the tray conveyance device 3, and the tray body member 22 of the tray 7 is detected from the detection result. An abnormality may have occurred. In this case, since no trouble occurs in the winding unit 4, a writing device (recording device) for storing trouble information in the IC tag 26 of the tray 7 is provided in the winding unit 4. It is not necessary and may be provided at an appropriate place in the tray transport device 3.

(Modification 8)
As shown in FIG. 4, when the IC tag 26 is disposed in the tray main body member 22, if the cover member 27 protecting the IC tag 26 is detached from the base 23 or damaged, the IC tag 26 The tag 26 may be damaged. Therefore, the cover member 27 may be dropped or the cover member 27 may be damaged by a camera or the like, and an abnormality may occur in the tray body member 22 of the tray 7 based on the detection result.

  In addition, when there are two or more types of problems that may occur due to the tray main body member 22 in relation to the modified embodiments 6 to 8, the input unit 70 of the machine control device 5 determines whether or not the tray main body member 22 is abnormal. It is preferable to be able to set the type of failure used to do this. For example, either the malfunction of the inclination of the yarn feeding bobbin 8 exemplified in the embodiment and the malfunction of the feeding failure of the tray 7 exemplified in the modified embodiment 6 are selectively used, or both malfunctions. It is possible to determine whether or not an abnormality has occurred in the tray main body member 22.

F] In the above embodiment, the tray 7 has the IC tag 26 storing the tray number (tray identification information) and the defect information. However, the tray 7 does not necessarily have to have a memory member such as the IC tag 26. Absent.

(Modification 9)
For example, a barcode including tray identification information may be attached to the tray body member 22. In that case, a barcode reader is provided at an appropriate position of the winding unit 4 or the tray transport device 3. The tray 7 is identified by reading the barcode of the tray body member 22 with this barcode reader. In this case, since the tray 7 cannot hold the failure information, the failure information is stored in a device different from the tray 7, for example, the unit control unit 63 of the winding unit 4 or the machine base control device. 5 is stored in a tray information storage unit provided at 5 etc.

  When a trouble occurs due to an abnormality in the tray body member 22 for a certain tray 7, the barcode is read by a barcode reader, and the tray 7 is identified. Then, the unit control unit 63 or the machine base control device 5 refers to the defect information about the tray 7 from the tray information storage unit, and determines whether or not an abnormality has occurred in the tray main body member 22 of the tray 7. judge.

G] (Modification 10)
The abnormal tray stop position Ps for stopping the tray 7C determined to be abnormal can be appropriately changed as follows. For example, as shown in FIG. 10, the abnormal tray stop position Ps is provided in the main conveyance path 14 when the tray conveyance device 3 is configured not to include the branch collection path 16 branched from the main conveyance path 14. May be. In this case, the abnormal tray stop position Ps is preferably provided in the recovery path 14b in the main transport path 14. For example, as in the configuration of the above-described embodiment, when determining the abnormality of the tray 7 with reference to the failure information read from the IC tag 26 by the reading / writing device 35 of the winding unit 4, the winding unit 4 In addition, the abnormal tray stop position Ps is preferably provided on the downstream side of the transport path of the tray transport device 3. Further, when the reading device 80 is provided in the collection path 14b as in the configuration of the modification 1 in FIG. 9, the abnormal tray stop position Ps is provided in the collection path 14b on the downstream side of the reading device 80. Is good.

H] (Modification 11)
In the above-described embodiment, the tray 7 determined to be abnormal in the winding unit 4 is stopped at the abnormal tray stop position Ps that is farther downstream than the winding unit 4. On the other hand, the tray 7C determined to be abnormal may be stopped as it is at a position where a defect is detected or a position where the reading device is provided. For example, if it is the structure of the said embodiment, when the tray control part 63 of each winding unit 4 determines that a certain tray 7C is abnormal, the tray 7C may be stopped in the winding unit 4. In this embodiment, the unit controller 63 does not need to recognize which tray 7 is determined to be abnormal, that is, the tray number of the tray 7. That is, the tray 7 does not have to include an identification unit having tray identification information, such as the IC tag 26.

I] (Modification 12)
The automatic winder 1 of FIG. 11 further includes a ring spinning machine 90 that spins the yarn wound around the yarn feeding bobbin 8, and the ring spinning machine 90 and a plurality of winding units 4 are connected by the tray transport device 3. Specifically, the ring spinning machine 90 is connected to the supply path 14 a of the tray transport device 3 via the bobbin preparation device 2. The ring spinning machine 90 is also connected to the collection path 14b of the tray transport device 3.

  The ring spinning machine 90 has a large number of spinning units (not shown). In these spinning units, yarn is simultaneously spun and wound around the yarn feeding bobbin 8 to form an actual bobbin 8A. That is, the same number of yarn feeding bobbins (actual bobbins) as the spinning units in operation are manufactured by one doffing of the ring spinning machine 90. Further, the ring spinning machine 90 mounts the manufactured actual bobbin on the tray 7 and removes the empty bobbin from the collected tray 7. Therefore, in the automatic winder 1 of FIG. 11, the tray 7 (7A) on which the actual bobbin is mounted is conveyed to the bobbin preparation device 2 by the ring spinning machine 90, and the bobbin preparation device 2 feeds the yarn by the spout unit 12. After the bobbin 8 is extracted, the tray 7 is sent out to the supply path 14a of the tray conveying device 3. In addition, the tray 7 (7B) with the empty bobbins attached discharged from the plurality of winding units 4 is conveyed by the collection path 14b and collected by the ring spinning machine 90. Since the automatic winder 1 in FIG. 11 performs the same operation as the automatic winder 1 in FIG. 1 except for the above, the operation such as abnormality detection of the tray 7 does not change greatly.

  In the above-described embodiment, when a failure due to the abnormality of the tray main body member 22 is detected in each winding unit 4, the number N of occurrences of the failure for one tray 7 is determined within a certain determination time T0. When the threshold value N0 or more is reached, it is determined that an abnormality has occurred in the tray body member 22 (S5 in FIG. 8).

  On the other hand, although the same may be applied to the automatic winder 1 of FIG. 11, the above-mentioned “number N of occurrences of defects” is manufactured by one doffing of the ring spinning machine 90 instead of the determination time T0. It is good also as the frequency | count that the malfunction generate | occur | produced about one tray 7 during the supplied actual bobbin. In this case, the actual bobbin manufactured by the doffing of the ring spinning machine 90 is applied to the IC tag 26 of the tray 7 supplied from the ring spinning machine 90 by the recording device 91 provided in the tray sending unit of the ring spinning machine 90. A doffing number indicating whether or not it is attached is stored. This doffing number information is held in the IC tag 26 while an actual bobbin manufactured by the same doffing is supplied. Further, when a failure occurs in each winding unit 4, the failure information is stored in the IC tag 26 of the tray 7. Then, the unit control unit 63 of each winding unit 4 refers to the doffing number and defect information stored in the IC tag 26 of each tray 7 while the actual bobbin manufactured by the same doffing is supplied. When the number of occurrences of defects is equal to or greater than the determination threshold, it is determined that an abnormality has occurred in the tray body member 22 of the tray 7.

  Further, in the automatic winder 1 of FIG. 11, the abnormal tray stop position Ps is particularly preferably provided in the collection path 14 b of the tray transport device 3. The reason is as follows. In order not to stop the ring spinning machine 90, in general, the processing capacity of a plurality of winding devices (formation of packages per unit time) is more than the processing capacity of the ring spinning machine 90 (number of actual bobbins formed per unit time). Number) is set high. Therefore, even during the normal operation of the automatic winder 1, a waiting time occurs in the collection path 14b for collecting the tray 7 from the plurality of winding units 4 to the ring spinning machine 90, and the tray 7 remains. In this regard, if the abnormal tray stop position Ps is set in the recovery path 14b, even if the recovery of the tray 7 is stopped by stopping the abnormal tray 7C in the recovery path 14b, the processing of the ring spinning machine 90 is performed. And the processing of the plurality of winding units 4 is not affected.
