The chase portion 21b is a yarn layer end portion of the yarn feeding bobbin 21 as the winding operation proceeds. Further, the chase portion detection sensor 74 is configured as a transmissive photosensor having a light projecting portion 74a and a light receiving portion 74b. As shown in FIG. 3, the detection signal detected by the chase unit detection sensor 74 is input to the unit control unit 50.

  With this configuration, the movable member 72 can be positioned at a predetermined distance from the chase portion 21 b by operating the elevating member 73 based on the detection signal of the chase portion detection sensor 74. Then, as the yarn feeding bobbin 21 is unwound and the position of the chase portion 21b is lowered, the elevating member 73 is lowered so that the distance between the chase portion 21b and the movable member 72 can be always constant. Thereby, when the yarn feeding bobbin 21 is unwound, the balloon generated at the position where the yarn is dissociated from the chase portion 21b can be appropriately regulated, and the tension of the yarn unwound from the yarn feeding bobbin 21 is kept constant. Winding work can be performed while keeping In order to perform such an appropriate unwinding assisting operation, it is necessary to align the unwinding side end of the yarn feeding bobbin 21 with the position (unwinding reference position) on the virtual line L1. The details of the control for adjusting the position of the unwinding side end of the yarn feeding bobbin 21 will be described later.

  Further, on the back side of the unwinding assisting device 12, a yarn crimping prevention device 11 for preventing the yarn from being crimped is disposed.

Appropriate negative pressure sources are connected to the lower thread guide pipe 25 and the upper thread guide pipe 26, respectively, and a suction force can be generated in the suction port 32 and the suction mouth 34.

  With this configuration, when the yarn feeding bobbin is replaced, the suction port 32 of the lower thread guide pipe 25 rotates downward to suck and capture the lower thread, and then rotates upward about the shaft 33. Thus, the lower thread is guided to the yarn joining device 14. At substantially the same time, the winder unit 4 rotates the upper thread guide pipe 26 upward from the position shown in FIG. 2 about the shaft 35 and reversely rotates the package 29 to be unwound from the package 29. The thread is captured by the suction mouse 34. Subsequently, the winder unit 4 guides the upper thread to the yarn joining device 14 by rotating the upper thread guide pipe 26 downward about the shaft 35. In the yarn joining device 14, the yarn joining of the lower yarn and the upper yarn is performed.

  Further, a notification lamp 56 is arranged on the unit frame 5 as shown in FIGS.

A swing arm 83 is disposed on the back side of the main core member drive cam 81, and a rotatable bearing 82 is attached to a middle portion of the swing arm 83. The bearing 82 is configured to be able to rotate appropriately while contacting the outer peripheral surface of the main core member drive cam 81.

  The tip of the swing arm 83 is connected to the lower end of a positioning arm 84a supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. A rotatable rotating member 87 is supported on the upper end portion of the positioning arm 84a.

  A contact arm 84b is disposed on the front side of the positioning arm 84a. The tip of the contact arm 84b is configured to be able to contact the rotating member 87 attached to the positioning arm 84a. One end of the transmission shaft 85 is fixed to the base portion of the contact arm 84 b, and the other end of the transmission shaft 85 is fixed to the main core member 80. That is, the transmission shaft 85 and the main core member 80 are configured to be interlocked. Accordingly, the main core member 80 rotates integrally with the contact arm 84b. Further, a torsion coil spring-like pressing spring 86 is attached to the contact arm 84b, and urges the contact arm 84b in the direction of the arrow in FIG.

  With the above configuration, since the elastic force of the pressing spring 86 acts on the contact arm 84b, the protruding portion contacts the rotating member 87 and pushes the positioning arm 84a. Furthermore, since the lower end portion of the positioning arm 84a pulls the swing arm 83 through the link, the bearing 82 of the swing arm 83 is pressed against the main core member drive cam 81. Thus, the pressing spring 86 makes the main core member drive cam 81 and the bearing 82 contact, and generates a spring force for bringing the contact arm 84b into contact with the positioning arm 84a.

  In this state, when the main core member driving cam 81 rotates and the peripheral edge portion (bulging portion described later) of the main core member driving cam 81 presses the bearing 82, the swing arm 83 rotates in a direction away from the cam shaft 105. The tip of the swing arm 83 pulls the lower end of the positioning arm 84a through the link. As a result, the rotation member 87 at the upper end of the positioning arm 84a pushes the contact arm 84b, so that the main core member 80 can be swung to the front side together with the contact arm 84b (see FIG. 8).

  In addition, the power transmission unit 120 is configured to transmit the power of the stepping motor 100 to the auxiliary core member 90, as an auxiliary core member drive cam (fixed cam) 91, a bearing 92, a swing arm 93, and a transmission arm 94. And a transmission shaft (holding interlocking member) 95 and a holding spring (holding elastic member) 96.

  The auxiliary core member drive cam 91 is fixed to the cam shaft 105 in the same manner as the main core member drive cam 81. A swing arm 93 is disposed on the back side of the auxiliary core member drive cam 91, and a rotatable bearing 92 is attached to a middle portion of the swing arm 93. The bearing 92 is configured to be able to rotate as appropriate while in contact with the outer peripheral surface of the auxiliary core member drive cam 91.

  The tip of the swing arm 93 is connected to the lower end of a transmission arm 94 supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. One end of a transmission shaft 95 is attached to the base of the transmission arm 94, and the other end of the transmission shaft 95 is fixed to the auxiliary core member 90. That is, the transmission shaft 95 and the auxiliary core member 90 are configured to be interlocked. Therefore, the auxiliary core member 90 rotates integrally with the transmission arm 94. Further, a torsion coil spring-like holding spring 96 is attached to the transmission arm 94, and the transmission arm 94 is urged in the direction of the dotted line arrow in FIG.

  With the above-described configuration, the holding spring 96 applies the spring force in the direction in which the auxiliary core member 90 swings to the back side (the direction away from the main core member 80) via the transmission arm 94 and the transmission shaft 95. 90. At the same time, the distal end portion of the transmission arm 94 to which the elastic force of the holding spring 96 acts pulls the swing arm 93 through the link, so that the bearing 92 of the swing arm 93 is pressed against the auxiliary core member drive cam 91. In this manner, the holding spring 96 generates a spring force for bringing the auxiliary core member drive cam 91 and the bearing 92 into contact with each other.

  In this state, when the auxiliary core member drive cam 91 rotates and the peripheral edge portion (a bulge portion described later) of the auxiliary core member drive cam 91 presses the bearing 92, the swing arm 93 swings away from the cam shaft 105. The tip of the swing arm 93 pulls the lower end of the transmission arm 94 through the link. As a result, the auxiliary core member 90 can be swung to the front side (direction approaching the main core member 80).

  In addition, when the auxiliary core member 90 is swung to the front side beyond a predetermined angle, the auxiliary core member 90 comes into contact with an unillustrated portion of the main core member 80, and thereafter, the auxiliary core member 90 is the main core member 90. The core member 80 is configured to swing as a single unit (in this case, the distal end portion of the contact arm 84b and the rotating member 87 are appropriately separated). That is, in a state where the auxiliary core member 90 is swung to the front side beyond a predetermined angle, the main core member 80 is driven by the auxiliary core member driving cam 91 instead of the main core member driving cam 81. .

  Next, a configuration for driving the jump plate 40 will be described. The power transmission unit 120 is configured to transmit the power of the stepping motor 100 to the jump plate 40, and includes a jump plate drive cam (discharge cam) 41, a bearing 42, a swing arm 43, a transmission arm 44, and a transmission shaft. (Discharge interlocking member) 45 and a return spring (discharge elastic member) 46 are provided.

  The jump plate drive cam 41 is fixed to the cam shaft 105 in the same manner as the auxiliary core member drive cam 91 and the main core member drive cam 81. A swing arm 43 is disposed on the back side of the jump plate drive cam 41, and a rotatable bearing 42 is attached to a middle portion of the swing arm 43. The bearing 42 is configured to be able to rotate as appropriate while in contact with the outer peripheral surface of the spring plate drive cam 41.

  The tip of the swing arm 43 is connected to the lower end of the transmission arm 44 supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. One end of the transmission shaft 45 is fixed to the base portion of the transmission arm 44, and the other end of the transmission shaft 45 is fixed to the spring plate 40. That is, the transmission shaft 45 and the jump plate 40 are configured to be interlocked. Therefore, the spring plate 40 rotates integrally with the transmission arm 44. Further, a torsion coil spring-like return spring 46 is attached to the transmission arm 44 to urge the transmission arm 44 in the direction of the arrow in FIG.

  With the above configuration, the distal end portion of the transmission arm 44 to which the elastic force of the return spring 46 acts pulls the swing arm 43 through the link, so that the bearing 42 of the swing arm 43 presses against the jump plate drive cam 41. It is done. In this way, the return spring 46 generates a spring force for bringing the spring plate drive cam 41 and the bearing 42 into contact with each other.

  In this state, when the jump plate drive cam 41 rotates and the peripheral portion (bulge portion described later) of the jump plate drive cam 41 presses the bearing 42, the swing arm 43 moves in a direction away from the cam shaft 105, and the swing plate drive cam 41 moves. The tip of the moving arm 43 pulls the lower end of the transmission arm 44 through the link. As a result, the jump plate 40 can be flipped up to the front side (see FIG. 9).

  Next, a configuration in which the winder unit 4 receives the yarn feeding bobbin 21, holds the yarn feeding bobbin 21 at a predetermined position where the yarn 20 is unwound, and discharges it will be described. As described above, in the present embodiment, the jump plate driving cam 41, the main core member driving cam 81, and the auxiliary core member driving cam 91 are configured as the cam coupling mechanism 130 fixed to the common cam shaft 105. The two cams 41, 81, 91 are integrally driven. Further, as shown in FIG. 6, the three cams 41, 81, 91 are respectively formed with bulges, and the postures of the jump plate 40, the main core member 80, and the auxiliary core member 90 are changed by the bulges. Can do. Although the bulge part (holding cam operation area) of the auxiliary core member drive cam 91 and the bulge part (discharge cam operation area) of the jump plate drive cam 41 are gently formed, the bulge part (regulation) of the main core member drive cam 81 is defined. The cam operation region) is formed slightly sharper. In addition, the bulging portion of the auxiliary core member driving cam 91 and the bulging portion of the jump plate driving cam 41 are formed in substantially the same phase, while the bulging portion of the main core member driving cam 81 is formed in a phase that is substantially 180 ° different from them. Has been.

  In the above configuration, when the yarn feeding bobbin 21 is received, the stepping motor 100 is appropriately driven to rotate the three cams 41, 81, 91, and the bearing 92 included in the swing arm 93 is used to drive the auxiliary core member. The cam 91 is brought into contact with a portion slightly passing the peak portion of the bulging portion, and the rotation of the cams 41, 81, 91 is stopped in this state. Thereby, as shown in FIG. 7, the auxiliary core member 90 is slightly tilted from the upright state to the front side.

  In this state, since the auxiliary core member 90 is swung beyond a predetermined angle, the main core member 80 is also swung to the front side in a form pushed by the auxiliary core member 90 as described above. As in the auxiliary core member 90, the posture is slightly tilted from the upright state to the front side. When the yarn feeding bobbin 21 is supplied from the magazine holding unit 61 in this state, the bobbin holding unit 110 (the main core member 80 and the auxiliary core member 90) enters the core tube 21a. In this specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is received (the posture in FIG. 7) is referred to as a receiving posture.

  When the yarn is unwound from the received yarn feeding bobbin 21, the stepping motor 100 is driven again to rotate the cam shaft 105 in the direction indicated by the arrow in FIG. Thereby, the bearings 42 and 92 which the rocking | fluctuation arms 43 and 93 have pass the bulge part completely in the spring board drive cam 41 and the auxiliary core member drive cam 91, and come to contact a non-bulge part. Further, the bearing 82 included in the swing arm 83 comes into contact with the bulging portion of the main core member drive cam 81.

  Accordingly, as shown in FIG. 8, the jumping plate 40 swings from the state of FIG. 7 to the back side and becomes horizontal, and the auxiliary core member 90 swings so that it slightly falls to the back side. Further, as described above, the main core member 80 that has been pushed to the front side by the auxiliary core member 90 also swings to the back side in the same manner as the auxiliary core member 90 swings to the back side. Eventually, the contact arm 84 b comes into contact with the rotating member 87 of the positioning arm 84 a to stop the main core member 80 from swinging. Thereafter, only the auxiliary core member 90 swings back by the spring force of the holding spring 96. It will be. That is, since the auxiliary core member 90 is displaced so as to be relatively away from the main core member 80, the core tube 21a of the yarn supplying bobbin 21 can be held from the inside by the bobbin holding portion 110.

  At this time, the posture in which the swing of the main core member 80 is stopped is determined by the position of the rotating member 87 of the positioning arm 84a. Further, since the positioning arm 84a is connected to the swing arm 83 via a link, the posture of the main core member 80 is such that the bearing 82 of the swing arm 83 is in the bulge portion of the main core member drive cam 81. It can be changed depending on which part is in contact (whether it is in contact with the rising part of the bulging part or the peak part). In other words, the posture of the main core member 80 can be adjusted by changing the rotational phase of the main core member drive cam 81. Even when the posture of the main core member 80 is changed in this way, the auxiliary core member 90 can maintain the holding state of the yarn feeding bobbin 21 without any problem by the elastic force of the holding spring 96.

  In this specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is unwound is referred to as the unwinding posture. In addition, the origin sensor 101 detects the rotational phase of the pulley 104 in a state where the main core member 80 is in an almost upright posture as shown in FIG. It is set to be the origin. Since the unwinding posture of the main core member 80 changes depending on the type of the yarn feeding bobbin 21, the origin detected by the origin sensor 101 does not always match the unwinding posture.

  Next, when discharging the yarn feeding bobbin 21, the stepping motor 100 is appropriately driven to rotate the three cams 41, 81, 91. As a result, the bearings 42 and 92 of the swing arms 43 and 93 come into contact with the bulging portions of the jump plate driving cam 41 and the auxiliary core member driving cam 91. Therefore, as shown in FIG. 9, the spring plate 40 swings greatly to the front side. Further, in conjunction with this, the auxiliary core member 90 swings to the front side to release the holding of the yarn feeding bobbin 21, and the auxiliary core member 90 greatly increases the front side while pushing the main core member 80. Swing. Thereby, the spring board 40 pushes up the lower end of the core tube 21a of the yarn supplying bobbin 21, and the yarn supplying bobbin 21 can be discharged. In the present specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is discharged is referred to as a discharging posture.

  As described above, in the present embodiment, the yarn feeding bobbin 21 is received and held in the unwinding posture (and the unwinding posture) only by driving the stepping motor 100 as a single drive source. Adjustment) and the yarn feeding bobbin 21 can be discharged.

  Next, with reference to FIGS. 10 to 12, a series of flows when the automatic winder 1 performs winding while replacing the yarn feeding bobbin 21 will be described. FIG. 10 is a flowchart showing a process performed by the winder unit 4 when a yarn break or the like occurs. FIG. 11 is a side view showing the first half of the state in which the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted. FIG. 12 is a side view showing the latter half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted. In addition, the process shown in this flowchart and the flowchart shown below is an example, and the effect of this invention may be acquired by changing the processing content and changing the processing order.

  During the winding operation by the winder unit 4, the clearer 15 detects the yarn defect and cuts the yarn with the cutter 39, the yarn breakage of the yarn being unwound from the yarn feeding bobbin 21 occurs, or the yarn feeding bobbin In some cases, the yarn 20 may be lost after the yarn 21 is unwound. The winder unit 4 monitors the yarn breakage (S101), and when the yarn breakage occurs, the winding operation is stopped (S102).

  Then, when the winding operation is stopped, the lower thread suction and capture by the suction port 32 of the lower thread guide pipe 25 positioned below and the upper thread suction and capture by the upper thread guide pipe 26 are performed. The splicing is started (S102). Thereafter, the unit controller 50 determines whether or not there is a lower thread after piecing based on the detection result of the lower thread detection sensor 31 (S103).

  When the yarn is being cut or unwound by the cutter 39, the yarn remains in the yarn feeding bobbin 21, and the splicing is completed if no mechanical error occurs. Accordingly, the lower thread detection sensor 31 detects the lower thread. At this time, the unit controller 50 controls each component of the winding unit body 6 to restart the winding of the yarn.

  On the other hand, when all the yarns in the yarn feeding bobbin 21 have been unwound and the yarn 20 is lost, the lower yarn detection sensor 31 does not detect the lower yarn because the yarn splicing cannot be performed. At this time, the unit control unit 50 determines that the yarn unwinding of the yarn supplying bobbin 21 has been completed, and operates the bobbin holding unit 110 and the jump plate 40 to perform the discharging process of the core tube 21a (S104). Thereafter, the unit controller 50 causes the bobbin supply device 60 to newly supply the yarn supplying bobbin 21 (S105). At this time, the stepping motor control unit 102 drives the stepping motor 100 to move the main core member 80 to the receiving posture in advance.

  The newly supplied yarn feeding bobbin 21 is guided to the bobbin setting unit 10 as shown in FIG. Then, the stepping motor control unit 102 swings the bobbin holding unit 110 toward the back side.

  Note that the winder unit 4 of the present embodiment has a layout of the bobbin holding unit 110 so that the yarn feeding bobbin 21 crosses the detection range of the chase detection sensor 74 when the bobbin holding unit 110 is swung back. Has been taken into account. Then, the determination unit 51 included in the unit control unit 50 determines whether or not the yarn feeding bobbin 21 is newly supplied based on the detection result of the chase unit detection sensor 74 (S106). Specifically, when the yarn feeding bobbin 21 is detected by the chase portion detection sensor 74 after the unit control unit 50 instructs to newly supply the yarn feeding bobbin 21, the determination unit 51 determines that the yarn feeding bobbin 21 It is determined that 21 is newly supplied. On the other hand, when the yarn feeding bobbin 21 is not detected by the chase portion detection sensor 74 within the predetermined time, the determination unit 51 determines that the yarn feeding bobbin 21 is not newly supplied.

  When the determination unit 51 determines that the yarn feeding bobbin 21 is newly supplied, the unit control unit 50 stores the determination result in the storage unit 52 provided in the unit control unit 50. The unit controller 50 then catches the newly supplied yarn end of the yarn feeding bobbin 21 and the yarn end on the package side, and starts piecing (S110).

  On the other hand, when the determination unit 51 determines that the yarn feeding bobbin 21 is not newly supplied, the unit control unit 50 stores the determination result in the storage unit 52. The unit controller 50 is configured to send an appropriate signal to the notification lamp 56 without starting the yarn splicing operation. The notification lamp 56 that has received this signal notifies the operator that the yarn feeding bobbin 21 is not newly supplied by using a preset display color or the like (S107).

  Then, the unit controller 50 of the present embodiment determines that the yarn feeding bobbin 21 is not newly supplied, sends an appropriate signal to the notification lamp 56, and continues until the trouble is resolved. The catching operation, the catching operation of the upper thread, and the yarn splicing are not performed. Further, the operator can know that the yarn feeding bobbin 21 is not supplied to the bobbin supply device 60 by the notification of the notification lamp 56. Then, the operator can stop the notification of the notification lamp 56 by supplying the yarn feeding bobbin 21 to the bobbin supplying device 60 (S108) and operating the error release button (S109). Thereafter, the bobbin supply device 60 newly supplies the yarn supplying bobbin 21 according to an instruction from the unit control unit 50 (S105). When the determination unit 51 determines that the yarn supplying bobbin 21 has been supplied, the unit control unit 50 captures the yarn end of the newly supplied yarn supplying bobbin 21 and the yarn end on the package side, and performs the yarn splicing. Is started (S110). The determination result of the determination unit 51 here is configured not to be stored in the storage unit 52.

  In the conventional configuration, since there is no sensor for detecting the presence / absence of the yarn feeding bobbin 21, it is determined whether or not to perform piecing based on the detection result of the lower yarn detection sensor. When the supply of the bobbin 21 fails, the following problem occurs. That is, in the conventional configuration, it is clear that the lower yarn cannot be captured when the yarn feeding bobbin is not supplied, but the yarn joining operation is attempted. An error occurred for the first time when the lower thread was not detected. Therefore, the conventional yarn winding machine also captures the upper thread when attempting to capture the lower thread, and the captured upper thread is eventually discarded due to the occurrence of an error. Resulting in. In addition, in the configuration that generates an error when the lower thread detection sensor does not detect the lower thread, the cause of the error is that the lower thread capturing means has caused a capturing error (mechanical error). The device side cannot determine whether 21 is not supplied (human error).

  In this regard, in the present embodiment, when the chase portion detection sensor 74 detects that the yarn supplying bobbin 21 is not present, the lower yarn capturing operation can be stopped. Therefore, the waste of the upper thread as described above can be prevented. Further, since the presence / absence of the yarn feeding bobbin 21 is detected by the chase portion detection sensor 74, the cause of the error can be clearly identified.

  Furthermore, in this embodiment, the time when a mechanical error occurs, the time when a human error occurs, and the like are stored in the storage unit 52 each time, and the calculation unit 53 included in the unit control unit 50 is based on the stored contents. Thus, the number of human errors in a predetermined time zone, the number of mechanical errors in a predetermined time zone, and the like can be calculated. The calculation result can be displayed on the unit display unit 19.

  As described above, in the present embodiment, it is possible to perform more appropriate measures against the error. Specifically, when errors due to the absence of supply of the yarn supplying bobbin 21 occur frequently, it is suspected that there is a problem in the operation of the operator supplying the yarn supplying bobbin 21 to the magazine can 62. Measures such as guidance can be appropriately taken. Further, since a human error is not counted as a mechanical error, a pure mechanical error can be detected, and an accurate maintenance operation can be performed.

  In addition to or instead of providing the winder unit 4 with the functions of the storage unit 52 and the calculation unit 53, the machine base control device 7 may have the functions as shown in FIG. FIG. 13 is a block diagram illustrating a modification of the machine base control device 7. In this configuration, the unit controller 50 outputs the time at which a mechanical error has occurred, the time at which a human error has occurred, and the like to the machine control device 7. And these are memorize | stored in the memory | storage part 252 with which the machine control apparatus 7 is provided. When the operator operates the machine base input unit 8 to specify an appropriate time zone, the calculation unit 253 provided in the machine base control device 7 calculates the number of human and mechanical errors in the time zone. To do. The calculation result can be displayed on the machine base display unit 9.

  Then, the unit control unit 50 adjusts the position of the unwinding side end of the yarn feeding bobbin 21 in parallel with the yarn splicing (S111). Hereinafter, the adjustment of the position of the unwinding side end of the yarn feeding bobbin 21 will be described in detail with reference to FIGS. 11, 12, and 14. FIG. 14 is a flowchart showing a process for adjusting the position of the unwinding side end of the yarn supplying bobbin 21.

  That is, in this embodiment, since the movable member 72 of the unwinding assisting device 12 is configured to cover the yarn feeding bobbin 21, the contact between the movable member 72 and the yarn feeding bobbin 21 is reliably prevented. . With this configuration, the winder unit 4 of the present embodiment is configured to accurately position the unwinding side end of the yarn feeding bobbin 21 at the unwinding reference position. The winder unit 4 of the present embodiment adjusts the position of the yarn feeding bobbin 21 using the chase part detection sensor 74 provided in the unwinding assisting device 12.

  This will be specifically described below. That is, the stepping motor control unit 102 controls the stepping motor 100 to rotate the main core member 80 in the receiving posture to the back side so that the yarn feeding bobbin 21 is once erected. At this time, the unit controller 50 applies the appropriate tension to the yarn 20 by bringing the brush portion 11b of the yarn crimping prevention device 11 into contact with the upper end portion of the yarn feeding bobbin 21 (see FIG. 11B), The occurrence of yarn crimping is prevented (S201). Thereafter, the stepping motor control unit 102 swings the bobbin holding unit 110 so as to slightly tilt the yarn feeding bobbin 21 to the front side again (S202). Then, when the yarn feeding bobbin 21 is detected by the chase part detection sensor 74, the unit controller 50 stops the swinging of the bobbin holding part 110 (S203, FIG. 12 (a)).

  Further, the storage unit 52 provided in the unit control unit 50 can move the yarn feeding bobbin 21 to an appropriate position if the stepping motor 100 is driven by how many pulses from the position where the yarn feeding bobbin 21 starts to be detected by the chase detection sensor 74. (Adjustment distance) is stored in association with the type of yarn feeding bobbin 21 to be used. The operator inputs the type of yarn feeding bobbin 21 to be used to the unit input unit 18 before starting the winding operation. Thereby, the adjustment distance which should be used in the present winding operation | work is set to the unit control part 50. FIG. Then, the unit control unit 50 outputs a predetermined number of pulses to the stepping motor 100 based on the set adjustment distance, and swings the bobbin holding unit 110 to the back side (S204, FIG. 12B). ).

  Thereby, the unwinding side end of the yarn feeding bobbin 21 can be adjusted to the unwinding reference position. Therefore, the contact between the movable member 72 and the yarn feeding bobbin 21 can be prevented while appropriately exerting the function of the unwinding assisting device 12.

  If the type of the yarn feeding bobbin 21 to be used is changed, an appropriate adjustment distance can be set in the unit control unit 50 by performing an appropriate input to the unit input unit 18. Further, this input can be made to the machine base input unit 8 instead of being made to the unit input unit 18. In this case, the machine base control device 7 transmits the content input to the machine base input unit 8 to each winder unit 4. Thereby, an appropriate adjustment distance can be set collectively for the unit control unit 50 of each winder unit 4.

  As described above, the winder unit 4 of the present embodiment includes the main core member 80, the drive unit 200, and the stepping motor control unit 102. The main core member 80 defines the posture of the yarn feeding bobbin 21. The drive unit 200 is driven to adjust the posture of the main core member 80 at the unwinding position where the yarn of the yarn supplying bobbin 21 is unwound. The stepping motor control unit 102 controls the stepping motor 100 of the driving unit 200.

  Thereby, in the winder unit 4 of this embodiment, since adjustment of the attitude | position of the main core member 80 in a unwinding position can be automatically performed by the stepping motor control part 102, the structure which performs adjustment of the attitude | position of the main core member 80 manually. Compared to the above, the burden on the operator can be reduced.

  Further, in the winder unit 4 of the present embodiment, the winder unit 4 includes an auxiliary core member 90 that holds the yarn feeding bobbin 21 on the main core member 80 by changing the posture with respect to the main core member 80. The drive unit 200 includes a stepping motor 100 and a power transmission unit 120. The power transmission unit 120 transmits the power of the stepping motor 100 to the main core member 80 and the auxiliary core member 90.

  Thereby, in the winder unit 4 of this embodiment, since the attitude | position of the main core member 80 and operation | movement of the auxiliary core member 90 can be controlled with the power of the common stepping motor 100, a structure can be made compact.

  Further, in the winder unit 4 of the present embodiment, the power transmission unit 120 includes a main core member drive cam 81 that changes the posture of the main core member 80.

  Thereby, in the winder unit 4 of the present embodiment, the operation of the main core member 80 can be determined based on the shape of the main core member drive cam 81. Further, in the winder unit 4 of the present embodiment, since the posture of the main core member 80 can be changed simply by rotating the cam shaft 105 to which the main core member drive cam 81 is attached, the configuration of the power transmission unit 120 is simplified. Can be.

  In the winder unit 4 of the present embodiment, the power transmission unit 120 includes a transmission shaft 85 and a pressing spring 86. The transmission shaft 85 is interlocked with the main core member 80. The pressing spring 86 applies an elastic force to the transmission shaft 85. The transmission shaft 85 is pressed against the main core member drive cam 81 by the elastic force of the pressing spring 86.

  Thereby, in the winder unit 4 of this embodiment, the attitude | position of a control member can be adjusted with the simple mechanism of the pressing spring 86 and the main core member drive cam 81. FIG.

  Further, in the winder unit 4 of the present embodiment, the power transmission unit 120 includes an auxiliary core member drive cam 91 that changes the posture of the auxiliary core member 90. By changing the attitude of the auxiliary core member 90 in accordance with the operation of the auxiliary core member drive cam 91, the attitude of the main core member 80 includes the receiving attitude for receiving the yarn feeding bobbin 21 and the unwinding attitude at the unwinding position. And a discharge posture in which the yarn supplying bobbin 21 is discharged.

  Thereby, in the winder unit 4 of this embodiment, since the attitude | position of the auxiliary core member 90 can be changed only by rotating the cam shaft 105 to which the auxiliary core member drive cam 91 is attached, the attitude of the main core member 80 is changed. Can be easily changed. Furthermore, in the winder unit 4 of the present embodiment, the member that holds the yarn feeding bobbin 21 on the main core member 80 in the unwinding position and the member that switches the posture of the main core member 80 can be made common. The score can be reduced. Therefore, in the winder unit 4 of the present embodiment, the configuration can be made compact and the manufacturing cost can be reduced.

  In the winder unit 4 of the present embodiment, the power transmission unit 120 includes a transmission shaft 95 and a holding spring 96. The transmission shaft 95 is interlocked with the auxiliary core member 90. The holding spring 96 applies an elastic force to the transmission shaft 95. The transmission shaft 95 is pressed against the auxiliary core member drive cam 91 by the elastic force of the holding spring 96.

  Thereby, in the winder unit 4 of this embodiment, the attitude | position adjustment of the auxiliary | assistant core member 90 can be performed with the simple mechanism of the holding spring 96 and the auxiliary | assistant core member drive cam 91. FIG. Further, the auxiliary core member 90 can be reliably operated according to the shape of the auxiliary core member drive cam 91.

  Further, in the winder unit 4 of the present embodiment, the main core member 80 and the auxiliary core member 90 are rotatably supported. The direction in which the main core member 80 rotates by the elastic force of the pressing spring 86 and the direction in which the auxiliary core member 90 rotates by the elastic force of the holding spring 96 are the same direction.

  Thereby, in the winder unit 4 of this embodiment, since arrangement | positioning of each cam 81,91 and the springs 86 and 96 can be simplified, a structure can be made compact.

  Further, in the winder unit 4 of the present embodiment, the winder unit 4 includes a spring plate 40 that discharges the yarn feeding bobbin 21 when the bobbin holding portion is in the discharging posture. The power transmission unit 120 includes a jump plate drive cam 41 and a transmission shaft 45. The jump plate drive cam 41 changes the posture of the jump plate 40. The transmission shaft 45 is interlocked with the jump plate 40.

  Thereby, in the winder unit 4 of this embodiment, since the attitude | position of the jump board 40 can be changed only by rotating the cam shaft 105 to which the jump board drive cam 41 is attached, the attitude | position of the jump board 40 is made easy. Can be changed.

  Further, in the winder unit 4 of this embodiment, the winder unit 4 includes a return spring 46 that applies an elastic force to the transmission shaft 45. The transmission shaft 45 is pressed against the spring plate drive cam 41 by the elastic force of the return spring 46.

  Thereby, in the winder unit 4 of this embodiment, the attitude | position of the spring board 40 can be changed with the simple structure of the return spring 46 and the spring board drive cam 41. FIG. Further, according to the shape of the jumping plate driving cam 41, the jumping plate 40 can be reliably operated.

  In the winder unit 4 of the present embodiment, the cam coupling mechanism 130 is integrally driven via a common cam shaft 105. The main core member drive cam 81 operating region in which the main core member drive cam 81 adjusts the posture of the main core member 80 is an auxiliary core member drive cam 91 operating region in which the auxiliary core member drive cam 91 changes the posture of the auxiliary core member 90. The jump plate drive cam 41 is configured to be different from the operation region of the jump plate drive cam 41 that changes the posture of the jump plate 40.

  Thereby, in the winder unit 4 of the present embodiment, the operation of the main core member 80 can be separated from the operations of the auxiliary core member 90 and the jump plate 40 with a simple configuration. Therefore, the posture of the restricting member can be reliably adjusted with a simple configuration.

  In the winder unit 4 of this embodiment, the cam shaft 105 is connected to the stepping motor 100.

  Thereby, in the winder unit 4 of this embodiment, the manufacturing cost of the winder unit 4 can be significantly reduced compared with the structure provided with the stepping motor 100 with respect to each cam 41,81,91.

  Further, the winder unit 4 of the present embodiment includes a unit input unit 18 capable of inputting information related to the yarn feeding bobbin 21. The stepping motor control unit 102 controls the drive unit 200 based on the information input to the unit input unit 18.

  Thereby, the winder unit 4 of this embodiment can adjust the attitude | position of the yarn supplying bobbin 21 to the appropriate attitude | position according to the kind of yarn supplying bobbin 21 only by inputting into the unit input part 18. FIG. Therefore, in the winder unit 4 of the present embodiment, the working efficiency can be improved as compared with the configuration in which the posture of the yarn feeding bobbin 21 is manually adjusted.

  According to the second aspect of the present embodiment, an automatic winder 1 having the following configuration is provided. That is, the automatic winder 1 includes a winder unit 4, a machine base control device 7, and a machine base input unit 8. The machine base control device 7 controls each winder unit 4. The machine base input unit 8 is arranged in the machine base control device 7 and can input information related to the yarn feeding bobbin 21. The stepping motor control unit 102 controls the drive unit 200 based on the information received from the machine base input unit 8.

  As a result, in the automatic winder 1 of the present embodiment, the adjustment of the posture of the yarn feeding bobbin 21 in each winder unit 4 is collectively performed for a plurality of winder units 4 only by inputting to the machine base input unit 8. Can be made. Therefore, the working efficiency can be further improved as compared with the configuration in which the setting of the type of the yarn feeding bobbin 21 supplied to the winder unit 4 is performed for each winder unit 4 included in the automatic winder 1. .

  Next, a first modification of the above embodiment will be described with reference to FIGS. 15 to 18. FIG. 15 is a block diagram illustrating a main configuration of the winder unit 4 according to the first modification and the second modification. FIG. 16 is a flowchart illustrating a process of adjusting the position of the unwinding side end of the yarn feeding bobbin 21 according to the first modification. FIG. 17 is a side view showing the first half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted according to the first modification. FIG. 18 is a side view showing the latter half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted according to the first modification.

  In this modification, the same or similar members as those in the above-described embodiment may be denoted by the same reference numerals in the drawings, and description thereof may be omitted. Further, in this modified example, in order to make it easy to see the periphery of the yarn feeding bobbin 21, the illustration of the yarn curl occurrence prevention device 11 and the chase portion detection sensor 74 is omitted.

  In the above embodiment, whether or not the yarn feeding bobbin 21 is newly supplied is detected by the chase part detection sensor 74 of the unwinding assisting device 12, but in this modification, the bobbin provided inside the opening / closing part 68. The yarn feeding bobbin 21 is detected by the detection sensor 58. In this modification, the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted based on the detection result of the position detection sensor 59 instead of the chase detection sensor 74. Further, the unit control unit 50 of the winder unit 4 of the present modification has a configuration including a calculation unit 54 as shown in FIG. Hereinafter, the process which adjusts the position of the unwinding side edge part of the yarn feeding bobbin 21 is demonstrated concretely.

  Since the bobbin detection sensor 58 is disposed inside the opening / closing portion 68, when the yarn feeding bobbin 21 is newly supplied (S301), the yarn feeding bobbin 21 enters the detection range of the bobbin detection sensor 58 (FIG. 17). (See (a)). The determination unit 51 of the unit control unit 50 determines whether or not the yarn feeding bobbin 21 is newly supplied based on the detection result of the bobbin detection sensor 58 (S302). The method for determining whether or not the yarn supplying bobbin 21 has been newly supplied and the control performed by the unit controller 50 after the presence or absence of the yarn supplying bobbin 21 is determined can be performed in the same manner as in the above embodiment.

  The unit control unit 50 drives the stepping motor 100 to swing the bobbin holding unit 110 to the back side before and after the determination unit 51 determines whether or not the yarn feeding bobbin 21 is newly supplied (S303). . When the yarn feeding bobbin 21 is raised to the back side, the unwinding side end of the yarn feeding bobbin 21 is detected by the position detection sensor 59 (see FIG. 17B). The position detection sensor 59 has a linear detection range, and is arranged so that the detection range intersects the virtual line L1 described above. And the calculation part 54 with which the unit control part 50 is provided is the pulse number from an origin when the unwinding side edge part of the yarn feeding bobbin 21 exists in the momentary position (1st position) detected by the position detection sensor 59. Is calculated (S304).

  Then, when the bobbin holding portion 110 is further swung back, the unwinding side end portion of the yarn feeding bobbin 21 is not detected by the position detection sensor 59 (see FIG. 18A). At this time, the calculation unit 54 calculates the number of pulses from the origin when the unwinding side end of the yarn feeding bobbin 21 is at the momentary position (second position) when it is no longer detected by the position detection sensor 59 ( S305). Thereafter, the calculation unit 54 calculates the number of pulses from the origin at the third position, which is an intermediate position between the first position and the second position (S306).

  Then, the stepping motor control unit 102 drives the stepping motor 100 based on the calculated number of pulses at the third position, and swings the bobbin holding unit 110 to the front side (S307, FIG. 18 (b)). .

  Thereby, the unwinding side end of the yarn feeding bobbin 21 can be adjusted to the unwinding reference position. Therefore, the contact between the movable member 72 and the yarn feeding bobbin 21 can be prevented while appropriately exerting the function of the unwinding assisting device 12.

  The intermediate position may be a position that bisects the first position and the second position, but is not limited to this, and various positions may be adopted depending on the layout. it can. Further, the count of the number of pulses is obtained by counting the pulses output from the stepping motor control unit 102 to the stepping motor 100.

  In the first modification, the first position, the second position, and the third position are calculated, but instead, the following method may be used. That is, the first position is calculated, and the pulses output from the stepping motor control unit 102 to the stepping motor 100 are counted from the first position until the moment when the unwinding side end of the yarn feeding bobbin 21 is not detected. . Then, a method of performing alignment by returning the bobbin holding unit 110 by a distance corresponding to half of the counted number of pulses (turning to the front side) can be considered.

  Next, a second modification of the above embodiment will be described with reference to FIGS. 15 and 19 to 21. FIG. 19 is a flowchart showing processing for adjusting the position of the unwinding side end of the yarn supplying bobbin 21 according to the second modification. FIG. 20 is a side view showing the first half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted according to the second modification. FIG. 21 is a side view showing the latter half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted according to the second modification.

  In this modification, the same or similar members as those in the above-described embodiment may be denoted by the same reference numerals in the drawings, and description thereof may be omitted. Further, in this modified example, in order to make it easy to see the periphery of the yarn supplying bobbin 21, the illustration of the yarn curl occurrence preventing device 11 is omitted. Further, the winder unit 4 of the present modification also includes a calculation unit 54 as shown in FIG. In this modification, the position of the unwinding side end portion of the yarn feeding bobbin 21 is adjusted using the chase portion detection sensor 74. Hereinafter, the process which adjusts the position of the unwinding side edge part of the yarn feeding bobbin 21 is demonstrated concretely.

  When the yarn supplying bobbin 21 is newly supplied (S401, FIG. 20A), the unit controller 50 swings toward the back side of the bobbin holding unit 110 (S402). At this time, the calculation unit 54 determines the position from the origin when the unwinding side end of the yarn supplying bobbin 21 is at the position (first position, FIG. 20B) when it is detected by the chase detection sensor 74. The number of pulses is calculated (S403). Then, the yarn supplying bobbin 21 is further swung to the back side, and is in a position (second position, FIG. 21A) when the yarn supplying bobbin 21 is not detected by the chase portion detection sensor 74. The number of pulses from the origin at that time is calculated (S404).

  Then, the calculation unit 54 calculates the number of pulses from the origin at the third position, which is an intermediate position between the first position and the second position (S405). Thereafter, the stepping motor control unit 102 calculates a final adjustment distance based on the third position and the adjustment distance set based on the stored contents of the storage unit 52 (S406). Based on the final adjustment distance, the number of pulses to be output to the stepping motor 100 is determined.

  Then, the stepping motor control unit 102 drives the stepping motor 100 by the determined number of pulses, thereby rotating the bobbin holding unit 110 to the back side (S407, FIG. 21 (b)).

  Thereby, the unwinding side end of the yarn feeding bobbin 21 can be adjusted to the unwinding reference position. Therefore, the contact between the movable member 72 and the yarn feeding bobbin 21 can be prevented while appropriately exerting the function of the unwinding assisting device 12.

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

  In the embodiment and the modified example, when it is determined that the yarn feeding bobbin 21 is not supplied, the other processing is not performed until the error is resolved. Instead, for example, a predetermined number of times is performed. The yarn feeding bobbin 21 can be re-supplied.

  In the above-described embodiment and modification, the tubular movable member 72 is used in the unwinding assisting device 12, but instead of this, a linear guide member formed by a plate member having a guide hole, a wire, or the like, Various shapes of the movable member 72 such as a polygonal column member can be used.

  In the above embodiment and the modification, the unwinding reference position is set as the base of the unwinding assisting device 12, but the unwinding reference position may be a preset target position, The member that is the basis of the setting is not limited to the unwinding assisting device 12. For example, the unwinding reference position may be set in a winder unit 4 of a type that does not include the unwinding assisting device 12. In addition to being set based on the unwinding assisting device 12, the unwinding reference position is, for example, a position on the extension line of the center position where the yarn 20 is traversed with respect to the take-up bobbin 22, or the yarn feeding bobbin 21. A position on the vertical line of the guide member that guides the unwound yarn may be used.

  In the above embodiment and the modified example, the stepping motor 100 is used to drive the jump plate 40 and the bobbin holding unit 110. However, instead of this, for example, a servo motor, a linear motor, a voice coil motor, or the like is used. The power transmission unit 120 may be driven.

  In the above-described embodiment and modification, the transmissive photosensor is used for the chase detection sensor 74, the position detection sensor 59, and the bobbin detection sensor 58, but instead, for example, a reflective photosensor or the like is used. Anyway. Moreover, it is good also as a structure which detects the movement or state of the chase part of the yarn supply bobbin 21 by detecting the yarn supply bobbin 21 as an image with a camera instead of the structure which detects the yarn supply bobbin 21 with a sensor.

  In the above embodiment and the modification, a gate-type tension applying device is used as the tension applying device 13, but instead of this, for example, a known disk-type tension applying device is used, and a predetermined tension is applied to the traveling yarn. It may be configured to give.

  In the above embodiment and the modification, the pulse for controlling the stepping motor 100 is used for detecting the position of the bobbin holding unit 110. However, the position may be detected by feedback control of the servo motor. Moreover, you may detect the angle of the bobbin holding part 110 using an angle sensor.

  In the embodiment and the modification, the bobbin supply device 60 including the magazine can 62 is described. However, the bobbin supply device 60 supplies the yarn supplying bobbin 21 to a predetermined position where the yarn 20 is unwound. If there is, it is not restricted to this configuration. For example, it is good also as a structure provided with the column-shaped storage member which can stack and store the yarn supply bobbins 21 and to supply the yarn supply bobbins 21 from the storage members.

  In the embodiment and the modification, the bobbin supply device 60 including the magazine can 62 is described, but the configuration of the bobbin supply device 60 is not limited to this. For example, the bobbin supply device 60 may be a tray-type yarn supply bobbin supply device 60 that supplies a tray loaded with the yarn supply bobbins 21 to the unwinding position by conveying the tray with a conveyor belt. In the winder unit 4 including the tray type yarn feeding bobbin supply device 60, the position of the unwinding side end of the yarn feeding bobbin 21 is moved in the front-rear direction by switching the conveying direction of the conveyor, and the yarn feeding bobbin 21 is unwound. The position of the heel side end can be adjusted to the target position. In addition, a swing member that swings the tray at the unwinding position is provided, and the position of the unwinding side end of the yarn supplying bobbin 21 is adjusted to the target position by swinging the yarn supplying bobbin 21 at the unwinding position.
