The trays T on the transport path 10 are each transported in a direction indicated by an arrow in FIG. 3 by a conveyor mechanism (not shown).

  The bobbin processing device 3 is provided with a device for performing a predetermined process on the bobbin B on the transport path 10. Specifically, a bobbin ejecting device 41 for ejecting the yarn end of the yarn supplying bobbin Bs, a bobbin extracting device 42 for ejecting the discharge bobbin Bd from the tray T, and a bobbin attachment for attaching the bobbin B to the empty tray T. It has a device 43 and the like.

  As shown in FIG. 4, the output device 41 (the output processing unit of the present invention) is arranged along the supply path 31. The dispensing device 41 is a device for dispensing the yarn end of the yarn supplying bobbin Bs being conveyed on the supply path 31. The spouting process means that the tip end of the yarn wound around the yarn supplying bobbin Bs is pulled out, and the yarn end of the yarn supplying bobbin Bs is easily sucked and caught by the lower yarn suction 26 in the winding unit 7 (see FIG. 3). It is to leave it in a state. The output device 41 is electrically connected to the bobbin processing control unit 11 (see FIG. 2). A yarn amount sensor 44, which detects the amount of yarn wound around the yarn supplying bobbin Bs, is arranged near the dispensing device 41. The yarn amount sensor 44 is electrically connected to the bobbin processing control unit 11 (see FIG. 2).

  When the amount of the yarn detected by the yarn amount sensor 44 is sufficiently large, the bobbin processing control unit 11 controls the dispensing device 41 to perform the dispensing process on the yarn supplying bobbin Bs on which the yarn is wound. Let When the feeding process is successful, the tray T on which the yarn supplying bobbin Bs is mounted is sent to the winder 4 side through the supply path 31. If the output process fails or if the output process is not performed, the tray T is guided to the feed route 33 side by the destination switching unit 35 and passes through the circulation route 37 (further details will be described later). To).

  The bobbin extracting device 42 (the extracting portion of the present invention) is arranged along the return path 34. The bobbin removing device 42 is a device mainly for extracting the discharge bobbin Bd from the tray T. The bobbin removing device 42 is arranged so as to extend in the vertical direction (see FIG. 5A). A bobbin sorting device 45 is connected to the bobbin removing device 42 (see FIG. 5A). Details of the bobbin sorting device 45 will be described later.

  As shown in FIG. 4, in the vicinity of the branch point between the discharge path 32 and the return path 34, a residual thread sensor 46 for detecting whether or not any thread remains on the discharge bobbin Bd is arranged. The residual thread sensor 46 is electrically connected to the bobbin processing control section 11 (see FIG. 2). For example, when no yarn is detected by the residual yarn sensor 46, the tray T is returned to the spinning machine 2 through the discharge path 32. When the yarn is detected by the remaining yarn sensor 46, the tray T is guided to the return path 34 side by the destination switching unit 36.

  A yarn amount sensor 47 for detecting the amount of yarn remaining in the discharge bobbin Bd is arranged in a portion between the bobbin removing device 42 and the residual yarn sensor 46 in the transport direction. Different processing is performed in the bobbin removing device 42 based on the detection result of the yarn amount sensor 47 (details will be described later).

  Further, near the yarn amount sensor 47, a reading / writing unit 48 that reads information recorded in the RF tag 100 of the tray T and writes information in the RF tag 100 is arranged. The reading / writing unit 48 is electrically connected to the bobbin processing control unit 11 (see FIG. 2).

  The bobbin mounting device 43 (empty bobbin mounting portion of the present invention) is arranged on the downstream side of the bobbin removing device 42 in the transport direction. The bobbin mounting device 43 is configured so that the empty bobbin B can be mounted on the tray T that has been emptied by removing the bobbin B.

  Further, as described above, the bobbin processing device 3 has the bobbin processing control unit 11. The bobbin processing control unit 11 includes a CPU, a ROM, a RAM and the like. The bobbin processing control unit 11 controls each unit of the bobbin processing device 3 by the CPU according to the program stored in the ROM. In addition, the bobbin processing control unit 11 communicates with the machine base control device 5.

  Here, in the conventional bobbin processing apparatus, the standby path branched from the discharge path 32 is formed, and the defective bobbin is made to stand by on the standby path. In addition, the defective bobbins waiting on the standby path were taken out from the tray T one by one by the operator and replaced with empty bobbins. It takes time to perform such work. Further, if the operator does not perform the above-mentioned extraction work for some reason such as dealing with a trouble and the tray T on the standby path is full, the subsequent defective bobbin cannot enter the standby path. In such a case, the operation of the bobbin processing device 3 may be stopped. Therefore, in the present embodiment, when it is determined that the yarn supplying bobbin Bs in which the yarn is unwound by the winding unit 7 is a defective bobbin, the defective bobbin can be pulled out from the tray T without manpower. Thus, the yarn winding equipment 1 has the following configuration.

(Bobbin removal device)
First, the specific configuration of the bobbin removing device 42 will be described subsequently with reference to FIGS. As shown in FIG. 5B, the bobbin removing device 42 includes a conveyor mechanism 51, a pressing roller 52, and two guide members 53 arranged side by side in the vertical direction. The number of guide members 53 is not limited to this. The bobbin removing device 42 can also be provided with three guide members 53 as in the embodiment described later. The conveyor mechanism 51 includes belt feed rollers 54 and 55 which are vertically spaced apart from each other, and an endless belt 56 wound around the belt feed rollers 54 and 55. The belt feed roller 54 is rotationally driven by a motor 57. As a result, the endless belt 56 is driven and the belt feed roller 55 is driven to rotate. The left side portion (the side facing the return path 34) of the endless belt 56 travels upward.

  The pressing roller 52 and the guide member 53 are for removing the bobbin B from the tray T by pressing the bobbin B against the running endless belt 56. The pressing roller 52 and the guide member 53 (guide member 61) arranged at the lowermost position are supported by a support member 64 provided independently of the conveyor mechanism 51 via a link mechanism 65. The pressing roller 52 and the guide member 61 are movable by a link mechanism 65 between a first position (see a solid line) and a second position (see a chain double-dashed line). The guide member 61 connected to the link mechanism 65 is driven to move between the first position and the second position by, for example, the air cylinder 67. The air cylinder 67 is configured to be controllable by the bobbin processing control unit 11. When the pressing roller 52 and the guide member 61 are located at the first position, the bobbin B is pressed against the endless belt 56 and pulled out from the tray T. Since the bobbin B is not pressed against the endless belt 56 when the pressing roller 52 and the guide member 61 are located at the second position, the bobbin B is not pulled out from the tray T.

  The guide member 53 (guide member 62) disposed immediately above the guide member 61 is supported by the support member 64 via the link mechanism 66. The guide member 62 is configured to be movable by a link mechanism 66 so as to change the gap between the guide member 62 and the endless belt 56. The guide member 62 is closed by the biasing force of the spring 68 to the right via the link mechanism 66. As a result, the guide member 62 can sandwich the bobbin B between the guide member 62 and the endless belt 56. Further, the gap between the guide member 62 and the endless belt 56 can be changed according to the thickness of the bobbin B (for example, according to the presence or absence of thread). The bobbin B taken out of the tray T and conveyed upward is conveyed to a position above the guide member 62. The bobbin B carried to the upper part of the guide member 62 is adapted to drop diagonally downward to the left (see the arrow in FIG. 5B). In the present embodiment, all the extracted bobbins Bp extracted by the bobbin extracting device 42 move to the bobbin sorting device 45 side.

(Bobbin sorter)
Next, the bobbin sorting device 45 will be described. As shown in FIG. 5A, the bobbin removing device 42 is connected to a bobbin sorting device 45 (sorting unit of the present invention). The bobbin sorting device 45 is a device that sorts the extracted bobbins B (hereinafter, also referred to as extracted bobbins Bp) into a plurality of types. The bobbin sorting device 45 is arranged on the left side of the bobbin removing device 42 (the side from which the extracted bobbin Bp falls off the bobbin removing device 42). As shown in FIG. 5C, the bobbin sorting device 45 has a frame member 71 and a switching mechanism 72.

  The frame member 71 is a member in which an internal passage through which the extraction bobbin Bp passes is formed. As shown in FIG. 5C, the frame member 71 has a loading port 73 into which the extracted bobbin Bp dropped from the bobbin sorting device 45 is loaded, a common route 74, and a plurality of sorting routes 75 (first sorting route 76). And a second sorting path 77). The common path 74 is formed in the upper portion of the frame member 71. The common path 74 extends obliquely downward to the left. The extraction bobbin Bp can be dropped along the inclined portion of the common path 74. The first sorting path 76 and the second sorting path 77 are arranged below the common path 74 (downstream side in the moving direction of the sampling bobbin Bp). The first sorting path 76 and the second sorting path 77 are partitioned from each other by a partition member 78. The first sorting path 76 and the second sorting path 77 extend obliquely downward while the outlet portions are curved (see FIG. 5A). That is, the first sorting path 76 and the second sorting path 77 extend at least downward as they move toward the downstream side in the moving direction of the sampling bobbin Bp. In the moving direction of the sampling bobbin Bp, the first discharge box 111 is arranged on the downstream side of the first sorting path 76, and the second discharge box 112 is arranged on the downstream side of the second sorting path 77. The first discharge box 111 and the second discharge box 112 are configured to be able to store a plurality of extraction bobbins Bp. The 1st discharge box 111 and the 2nd discharge box 112 are equivalent to the storage part of the present invention.

  The switching mechanism 72 (switching unit of the present invention) is for switching to which sorting path 75 the extraction bobbin Bp is moved from the common path 74. As shown in FIG. 5C, the switching mechanism 72 has, for example, a rotating plate 81, a guide plate 82 (a guide member of the present invention), and an air cylinder 83 (a drive unit of the present invention). The switching mechanism 72 is configured to switch the destination of the extraction bobbin Bp by switching the position (angular position) of the guide plate 82 fixed to the rotatable rotating plate with the air cylinder 83.

  The rotating plate 81 is provided above the partition member 78 and is rotatably supported by the frame member 71. A projection 84 is provided on the end surface of the rotating plate 81, for example. The tip of the rod 85 of the air cylinder 83 is attached to the rotating plate 81 via a protrusion. The guide plate 82 is provided so as to be rotatable integrally with the rotating plate 81. The air cylinder 83 has an expandable rod 85. The tip of the rod 85 is attached to the protrusion 84 of the rotating plate 81. The air cylinder 83 is configured such that the rod 85 expands and contracts by supplying and discharging compressed air. The rotation plate 81 is rotated by the expansion and contraction of the rod 85, whereby the position (angle position) of the guide plate 82 is switched. Specifically, the guide plate 82 guides the extraction bobbin Bp to the first sorting path 76 at the first position (see the solid line in FIG. 5C), and the sampling bobbin Bp to the second sorting path 77 at the first position. The position can be switched between two positions (see the chain double-dashed line in FIG. 5C). The air cylinder 83 is configured to be controllable by the bobbin processing control unit 11.

(Control for bobbin removal process)
Next, a process of extracting the bobbin B from the tray T being transported on the transport path 10 of the bobbin processing device 3 will be described. In the present embodiment, as described below, the bobbin processing control unit 11 controls each unit of the bobbin processing device 3 to extract a plurality of types of bobbins B from the tray T by the bobbin removing device 42, and the bobbin sorting device. The sampling bobbins Bp are sorted by 45.

  First, prior to the control of the bobbin processing device 3 by the bobbin processing control unit 11, the discharge processing of the tray T from the winding unit 7 by the unit control unit 12 will be described with reference to the flowchart shown in FIG.

  In the initial state, the yarn Y is unwound from the yarn supplying bobbin Bs in the winding unit 7. When the unit controller 12 (see FIG. 2) does not determine that the yarn supplying bobbin Bs is the defective bobbin on which the defective yarn is wound according to the detection result of the yarn clearer 22 (S101: No), the yarn supplying The unwinding of the yarn from the bobbin Bs is continued to be performed by the winding unit 7. If the yarn supplying bobbin Bs is not empty (S102: No), the process returns to S101 to wait for a signal from the yarn clearer 22. When the remaining yarn sensor 46 detects that the yarn supplying bobbin Bs has become empty (S102: Yes), the unit controller 12 controls the ejector 30 (see FIG. 3) so that the yarn supplying bobbin B becomes empty. The tray T on which the bobbin Bs is mounted is ejected from the winding unit 7 (S103). Most of the normally discharged discharge bobbins Bd are empty bobbins in which no yarn remains, but a part of the discharge bobbin Bd may be a small amount residual yarn bobbin in which a small amount of yarn remains.

  On the other hand, when it is determined that the yarn supplying bobbin Bs is a defective bobbin based on the detection result of the yarn clearer 22 before the yarn supplying bobbin Bs becomes empty (S101: Yes), the unit controller 12 causes the winding unit 7 to rotate. The unwinding process of the yarn Y from the yarn supplying bobbin Bs is stopped. In addition, the unit controller 12 controls the reading / writing unit 28 (see FIG. 3) to provide the RF tag 100 (see FIG. 3) of the tray T with quality information indicating that the yarn supplying bobbin Bs is a defective bobbin. It is recorded (S104). Further, the unit controller 12 controls the ejector 30 (see FIG. 3) to eject the tray T having the empty yarn supply bobbin Bs (ejection bobbin Bd) attached thereto from the winding unit 7 (S103). .

  As described above, when the unwinding of the yarn Y from the yarn supplying bobbin Bs is normally completed, the quality information indicating that the discharging bobbin Bd is the defective bobbin is written in the RF tag 100 of the discharged tray T. Not not. On the other hand, when the yarn supplying bobbin Bs is a defective bobbin, quality information indicating that the discharging bobbin Bd is a defective bobbin is written in the RF tag of the discharged tray T.

  Next, control of the bobbin processing device 3 by the bobbin processing control unit 11 will be described with reference to FIGS. 7 to 11. FIG. 7 is a flow chart showing a process relating to the withdrawal and ejection of the bobbin B and the return of the tray T. In the following description, the tray T on which the yarn supplying bobbin Bs is mounted and the tray T on which the discharging bobbin Bd is mounted may coexist on the transport path 10 of the bobbin processing device 3. Therefore, unless otherwise necessary, the yarn supplying bobbin Bs and the discharging bobbin Bd are collectively referred to as a bobbin B. FIG. 8 is a flowchart showing a process from the time when the tray T is conveyed to the feeding device 41 side to the time when it is returned to the conveyance path 10 of the bobbin processing device 3 again. 9A to 9C and 10A to 10C are explanatory views showing the movement of the bobbin B on the transport path 10. 11A and 11B are explanatory views showing the operation of the bobbin sorting device 45.

  As an initial state, the tray T on which a certain bobbin B is mounted is located in front of the residual thread sensor 46 on the discharge path 32 (see FIG. 9A). Here, the bobbin B conveyed on the discharge path 32 is again subjected to the ejection processing due to the above-mentioned defective bobbin, empty bobbin, small amount of remaining yarn bobbin, and the ejection processing by the ejection device 41 having failed. Is one of the required bobbin.

  First, the residual thread sensor 46 detects whether or not any thread remains on the bobbin B. When no thread remains on the bobbin B (S201: No), the bobbin B is an empty bobbin and can be returned to the spinning machine 2. Therefore, the tray T on which the bobbin B is mounted is conveyed as it is on the discharge path 32 (return path of the present invention) (see FIG. 9B) and returned to the spinning machine 2 (S202). If any yarn remains on the bobbin B (S201: Yes), the bobbin processing control unit 11 controls the destination switching unit 36 to move the tray T to the return path 34 (see FIG. 9C). .

  Next, the amount of yarn remaining on the bobbin B is detected by the yarn amount sensor 47 (yarn amount detecting unit of the present invention). Yarn amount information regarding the amount of yarn is transmitted from the yarn amount sensor 47 to the bobbin processing control unit 11. When the amount of remaining yarn is not more than the predetermined amount (S202: No), the bobbin B is a small amount of remaining yarn bobbin. In this case, the bobbin processing control unit 11 controls the bobbin removing device 42 to remove the bobbin B from the tray T. Further, the bobbin processing control unit 11 controls the bobbin sorting device 45 to position the guide plate 82 at the first position (see FIG. 11A) and moves the extraction bobbin Bp to the first sorting path (S204). . As a result, the extraction bobbin Bp moves along the first sorting path 76 by the action of gravity and is discharged to the first discharge box 111. Further, the bobbin processing control section 11 controls the bobbin mounting device 43 (empty bobbin mounting section of the present invention) to mount the empty bobbin B on which the yarn is not wound on the tray T on which nothing is mounted ( S205).

  When the remaining yarn amount is equal to or larger than the predetermined amount (S202: Yes), the quality information recorded on the RF tag 100 of the tray T is read by the read / write unit 48 (quality information acquisition unit of the present invention). . The bobbin processing control unit 11 determines whether or not quality information indicating that the bobbin B is a defective bobbin is recorded on the tray T (S206). When the quality information is recorded on the tray T (S206: Yes), the bobbin processing control unit 11 controls the bobbin removing device 42 to remove the bobbin B from the tray T. Further, the bobbin processing control unit 11 controls the bobbin sorting device 45 to position the guide plate 82 at the second position (see FIG. 11B) and moves the sampling bobbin Bp to the second sorting path (S207). . As a result, the extracted bobbin Bp is discharged to the second discharge box 112. Further, the bobbin processing control unit 11 controls the bobbin mounting device 43 to mount the empty bobbin B on the empty tray T (S208).

  On the other hand, when the quality information is not recorded on the tray T (S206: No), the bobbin B mounted on the tray T is a bobbin with a large amount of remaining yarn although it is not a defective bobbin. Further, the bobbin B, which has no problem with the yarn quality but cannot be caught by the winding unit 7 when the yarn is cut, is also discharged from the winding unit 7 and conveyed through the return path 34. The bobbin B as described above is, for example, a bobbin for lead-out, which has failed the lead-out process by the lead-out device 41 and is circulating on the circulation path 37. Therefore, instead of removing the bobbin B from the tray T, the bobbin processing control unit 11 performs the following processing. That is, the bobbin processing control unit 11 controls the reading / writing unit 48 (the number-of-times information adding unit and the number-of-times information acquiring unit of the present invention) to provide the circulation information regarding the number of times the tray T has circulated, to the RF tag 100 ( It is recorded in the number-of-times information added portion of the present invention). More specifically, when the number of revolutions before recording is N, the bobbin processing control unit 11 controls the reading / writing unit 48 and outputs the number-of-times information indicating that the number of revolutions is N + 1 to the RF tag. It is written in 100 (S209). Furthermore, when the number of revolutions of the tray T at this time is a predetermined number of times (for example, 3 times) or more (S210: Yes), the bobbin processing control unit 11 controls the bobbin extracting device 42 to extract the bobbin B from the tray T. Let Further, the bobbin processing control unit 11 controls the bobbin sorting device 45 to position the guide plate 82 at the first position and discharges the extracted bobbin Bp to the first discharge box 111 (S211). In addition, the bobbin processing control unit 11 controls the bobbin mounting device 43 to mount the empty bobbin B on the empty tray T (S212).

  In this way, the bobbin processing control unit 11 controls the bobbin removing device 42 based on the quality information, the yarn amount information, and the number-of-times information, and executes the bobbin B removing process when the above information satisfies a predetermined condition. . The yarn amount information and the number-of-times information correspond to the state information of the present invention. The yarn amount sensor 47 and the reading / writing unit 48 correspond to the state information acquisition unit of the present invention. In addition, the bobbin processing control unit 11 controls the bobbin sorting device 45 based on at least the quality information. That is, the bobbin processing control unit 11 discharges the extracted bobbin Bp to the first discharge box 111 when the extracted bobbin Bp is not a defective bobbin, and discharges the extracted bobbin Bp to the second discharge box 112 when the extracted bobbin Bp is a defective bobbin. Let

  After that, the bobbin processing control unit 11 moves the tray T from the return path 34 to the supply path 31 (see FIG. 10A). That is, the tray T is conveyed to the output device 41 side (S213). After that, the tray T is supplied to the winding unit 7 according to the state of the bobbin B, or returns to the discharge path 32 again through the circulation path 37. Specific processing will be described mainly with reference to FIG.

  First, the remaining thread amount of the bobbin B mounted on the tray T being conveyed on the supply path 31 is detected by the thread amount sensor 44. The bobbin processing control unit 11 determines whether the remaining yarn amount of the bobbin B is equal to or more than a predetermined amount (S301). Here, when the bobbin B is an empty bobbin mounted on the tray T by the bobbin mounting device 43 described above, the remaining yarn amount is always less than or equal to the predetermined amount (S301: No). In this case, the bobbin processing control unit 11 controls the destination switching unit 35 to move the tray T to the feeding path 33 (see FIG. 10B). Then, the tray T on which the empty bobbin B is mounted is conveyed to the discharge path 32 and returned to the spinning machine 2 as it is (see FIG. 9B).

  On the other hand, when the remaining yarn amount of the bobbin B is equal to or more than the predetermined amount (S301: Yes), that is, when the bobbin B is the bobbin for the ejection to be subjected to the ejection processing, the bobbin processing control unit 11 causes the ejection device 41 is controlled to cause the bobbin B to perform the lead-out process (S303). When the output process is successful (S304: Yes), the bobbin process control unit 11 moves the tray T as it is to the winder 4 side (S305; see FIG. 10C). When the output process has failed (S304: No), the bobbin process control unit 11 controls the destination switching unit 35 to move the tray T to the feed path 33 (see FIG. 10B). The tray T moved to the feed path 33 is again conveyed to the discharge path 32 (see FIG. 9A).

  As described above, the read / write unit 48 can acquire the quality information of the bobbin B being transported on the transport path 10 of the bobbin processing device 3. Further, since the bobbin removing device 42 is controlled based on the quality information, the bobbin removing device 42 can remove the defective bobbin from the tray T. Therefore, when the yarn supplying bobbin Bs in which the yarn is unwound by the winding unit 7 is determined to be a defective bobbin, the defective bobbin can be pulled out from the tray T without manual labor.

  Further, the clearer control unit 22a of the yarn clearer 22 determines whether the yarn supplying bobbin Bs is a defective bobbin. Therefore, the processing load of the unit controller 12 can be reduced as compared with the case where the unit controller 12 functions as the determination unit of the present invention.

  Further, since the quality information is given to each tray T, it is possible to prevent data relating to the quality information from being concentrated on the bobbin processing control unit 11. Therefore, the risk of loss of the data can be suppressed.

  Further, the bobbin removing device 42 is controlled based on the state information in addition to the quality information. Therefore, the bobbins B other than the defective bobbin can be pulled out without manual labor.

  Further, the bobbin removing device 42 is also controlled based on the yarn amount information. Therefore, the discharge bobbin in which the yarn is normally unwound by the winding unit 7 and a small amount of the yarn remains can be extracted by the bobbin extracting device 42.

  Further, the bobbin removing device 42 is controlled also based on the information on the number of times the tray T has circulated on the transport path 10. Therefore, the bobbin extracting device 42 can also extract a bobbin in which the failure of the ejection process is repeated.

  Further, at least the bobbin sorting device 45 can be controlled based on the information as to whether or not the extracted bobbin Bp is a defective bobbin. Therefore, the defective bobbin and the other sampling bobbin Bp can be sorted.

  In addition, the defective bobbins and the other extraction bobbins Bp can be moved to different locations by the plurality of sorting paths 75. Therefore, the defective bobbin and the other extracted bobbin Bp can be easily and reliably sorted.

  Further, the removal bobbins Bp can be sorted by a simple operation of switching the position of the guide plate 82.

  Further, due to the action of gravity, the sampling bobbin Bp can be moved along the sorting path 75. Therefore, the cost can be reduced as compared with a configuration in which the sampling bobbin Bp is transported along the sorting path 75 by a mechanism such as a belt conveyor.

  Further, the extraction bobbin Bp is discharged to the first discharge box 111 or the second discharge box 112. As a result, it is possible to collect a plurality of sorted bobbins Bp that are sorted and stored and collectively process them. Therefore, for example, compared with the case where the extraction bobbins Bp on the sorting path 75 are processed one by one, the labor can be saved.

  Further, in the yarn winding equipment 1 in which the bobbin processing device 3 and the spinning frame 2 are connected, the defective bobbin is extracted from the tray T, an empty bobbin is mounted on the tray T, and the tray T on which the empty bobbin is mounted is rotated by the spinning frame 2 It is possible to perform the work until it is returned to the factory without any manual labor.

  Next, a modified example in which the above embodiment is modified will be described. However, components having the same configurations as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be appropriately omitted.

(1) In the above embodiment, all the extracted bobbins Bp extracted by the bobbin extracting device 42 are moved to the bobbin sorting device 45 side, but the present invention is not limited to this. This will be described below with reference to FIGS. 12 (a) to 12 (c) and FIG.

  As shown in FIGS. 12A and 12B, a guide member 91 may be provided further above the guide member 62 of the bobbin removing device 42. The guide member 91 is supported by the support member 64 via the link mechanism 92. The guide member 91 connected to the link mechanism 92 is provided between the first position (see the chain double-dashed line in FIG. 12A) and the second position (see the solid line in FIG. 12A) by, for example, the air cylinder 93. It is possible to move with. The air cylinder 93 is configured to be controllable by the bobbin processing control unit 11. When the guide member 91 is located at the second position (see FIG. 12A), the extraction bobbin Bp falls off from the gap formed between the guide member 62 and the guide member 91 toward the bobbin sorting device 45 side. To do. On the other hand, when the guide member 91 is located at the first position (see FIG. 12B), the extraction bobbin Bp is pressed against the endless belt 56 by the guide member 91. As a result, the extraction bobbin Bp moves to the uppermost part of the bobbin extraction device 42 by the endless belt 56. In this case, the bobbin removing device 42 also functions as the sorting section of the present invention. That is, the route of the extraction bobbin Bp formed by the guide member 91 and the endless belt 56 also corresponds to the sorting route of the present invention. In this way, the bobbin extracting device 42 may form the third sorting path. Further, like the switching mechanism 72, the guide member 91, the link mechanism 92, and the air cylinder 93 also correspond to the switching unit of the present invention. Further, as shown in FIG. 12C, the third discharge box 113 may be attached to the upper portion of the bobbin removing device 42. The third discharge box 113 is a discharge destination of the extracted bobbin Bp that has reached the uppermost portion of the bobbin extracting device 42.

  Furthermore, in the above-mentioned configuration, the bobbin processing control unit 11 may perform the following control, as shown in FIG. That is, when the number of revolutions of the tray T is equal to or greater than the predetermined number in S210 (S210: Yes), the bobbin processing control unit 11 controls the bobbin extracting device 42 to extract the bobbin B from the tray T. Further, the bobbin processing control unit 11 controls the bobbin removing device 42 to position the guide member 91 at the first position and ejects the extracted bobbin Bp to the third ejection box 113 (S214). That is, the bobbin processing control unit 11 may control the sorting unit based on the quality information and the state information. Thereby, the extracted bobbins Bp other than the defective bobbin can be further sorted.

The transport path 10a of the bobbin processing device 3a has a supply path 31a, a discharge path 32a, a feed path 33a, and a return path 34a. A circulation path 37a is formed by the supply path 31a, the discharge path 32a, the feed path 33a, and the return path 34a. The difference from the bobbin processing apparatus 3 (see FIG. 4) is that the supply path 31a and the return path 34a are not branched from each other, and the discharge path 32a and the return path 34a are not branched from each other. That is, unlike the bobbin processing device 3, the bobbin processing device 3a does not exchange the tray T with the spinning machine 2. Further, the bobbin mounting device 43a of the bobbin processing device 3a (yarn supply bobbin mounting portion of the present invention) does not mount the empty bobbin B on the empty tray T, but instead loads the fully wound yarn supply bobbin Bs on the empty tray T. It is configured to be attached to.

  Furthermore, in the above configuration, the bobbin processing control unit 11 may perform the following control. That is, the bobbin processing control unit 11 may cause the bobbin extracting device 42 to extract an empty bobbin in addition to the defective bobbin, the small amount residual yarn bobbin, and the bobbin for lead-out as described above. In this case, the yarn feeding bobbin Bs is mounted on the empty tray T. Hereinafter, a specific description will be given with reference to FIG. When no thread remains on the bobbin B in S201 described above (S201: No), that is, when the bobbin B is an empty bobbin, the bobbin processing control unit 11 controls the bobbin extracting device 42 to extract the bobbin B. , To the third discharge box 113 (S215). Further, the bobbin processing control unit 11 controls the bobbin mounting device 43a to mount the yarn supplying bobbin Bs on the empty tray T (S216). Similarly, when the small amount of remaining yarn bobbin, the defective bobbin, and the spout bobbin are respectively removed from the tray T, the bobbin processing control unit 11 controls the bobbin mounting device 43 to supply the yarn to the empty tray T. The bobbin Bs is mounted (S217, S218, S219, respectively). As a result, the work of pulling out the defective bobbin from the tray T and mounting the yarn supplying bobbin Bs on the tray T can be performed without manual labor. Further, the bobbin removing device 42 can both remove the defective bobbin and the empty bobbin. Therefore, the manufacturing cost can be reduced as compared with the configuration in which these bobbins B are separately extracted.

(4) In the embodiments described above, the first sorting path 76 and the second sorting path 77 extend at least downward as they move toward the downstream side in the moving direction of the sampling bobbin Bp. Not limited. For example, the first sorting path 76 and the second sorting path 77 extend in the horizontal direction, and the extraction bobbins Bp on these paths may be conveyed by a conveyor mechanism or the like.

(5) In the above-described embodiments, the discharge box is provided corresponding to each sorting path 75, but the present invention is not limited to this. For example, each sorting path 75 is configured so that the operator can access the sampling bobbin Bp, and the operator may process the sampling bobbin Bp one by one.

(6) Although quality information and frequency information are recorded in the RF tag 100 of the tray T in the above embodiments, the present invention is not limited to this. For example, the winding unit 7 may be configured such that a sticker having a bar code indicating that the bobbin B is a defective bobbin can be attached to the tray T or the bobbin B. In this case, the bobbin B also corresponds to the quality information added portion of the present invention. Alternatively, the winding unit 7 may be configured to be capable of transmitting quality information and frequency information to the machine control device 5. The machine control device 5 may be configured to be capable of being stored in association with the quality information and the number-of-times information and the identification information of the tray T. In this case, the machine control device 5 corresponds to the quality information applied part and the number-of-times information applied part of the present invention.

(7) In the above-described embodiments, the extraction bobbins Bp are sorted by the sorting path 75 and the switching mechanism 72, but the present invention is not limited to this. For example, the bobbin sorting device 45 may be configured such that a sticker or the like indicating that the extracted bobbin Bp is a defective bobbin can be attached to the extracted bobbin Bp. In this case, the bobbin sorting device 45 may discharge all the extracted bobbins Bp into one discharge box, and then the operator may perform visual sorting.

(8) In the embodiments described above, the bobbin processing control unit 11 causes the bobbin B other than the defective bobbin to be removed from the tray T by the bobbin removing device 42, but the present invention is not limited to this. For example, the bobbin processing device 3 may include a residual yarn removing device capable of removing a small amount of residual yarn from the small amount residual yarn bobbin (see Japanese Unexamined Patent Application Publication No. 2016-102004). Further, the lead-out bobbin may be circulated on the loop path 37 until the lead-out processing is successful. In these cases, the small amount of remaining yarn bobbin and the bobbin for delivery need not necessarily be extracted from the tray T by the bobbin extracting device 42. That is, the bobbin processing control unit 11 may cause only the defective bobbin to be extracted from the tray T by the bobbin extracting device 42. In this case, the bobbin sorting device 45 does not necessarily have to be provided.

(9) In the above embodiments, the yarn clearer 22 of the winding unit 7 monitors the yarn Y and determines the quality of the yarn supplying bobbin Bs, but the present invention is not limited to this. The monitoring unit and the determination unit may be provided separately. For example, the yarn clearer 22 may transmit the monitoring result of the yarn Y to the unit controller 12, and the unit controller 12 may determine the quality of the yarn supplying bobbin Bs. In this case, the yarn clearer 22 functions only as the monitoring unit of the present invention. The unit controller 12 functions as the determination unit of the present invention. That is, the determination unit of the present invention may be included in the unit control unit 12. Accordingly, even if the yarn clearer 22 cannot function as the determination unit of the present invention, the unit control unit 12 can determine whether the yarn supplying bobbin Bs is a defective bobbin.

(10) In the above embodiments, the bobbin processing control unit 11 controls each unit of the bobbin processing device 3, but the present invention is not limited to this. For example, the machine control device 5 may control each part of the bobbin processing device 3. In this case, the machine control device 5 corresponds to the bobbin processing control unit of the present invention.
