  • the predetermined distance can be a fixed value or a variable value.
  • the predetermined distance is changeably set (can be changed as desired) by the setting section 91.
  • the package driving motor 41 is controlled, and the normal rotation of the package 30 is slowed down and stopped.
  • the driving of the air cylinder 60 is controlled, and the package 30 is lifted up.
  • the rotation angle of the cradle 23 is detected by the angle sensor 44, and the upper yarn pipe arm 36 is pivoted so that the upper yarn suction port 35 comes near the package 30 based on the detected rotation angle. Accordingly, the upper yarn suction port 35 moves to the position at the predetermined distance from the surface of the package 30 to be in the separated state.
  • a control performed to move the upper yarn suction port 35 specifically, first, based on the rotation angle detected by the angle sensor 44 immediately before the lift-up, the position of the surface of the package 30 is grasped immediately before the lift-up.
  • a rotational driving amount of the upper yarn pipe arm 36 that is required to move the upper yarn suction port 35 to the position at the predetermined distance from the surface of the package 30 immediately before the lift-up (hereinafter, "reference rotational driving amount”) is calculated based on the grasped position of the package 30 surface.

  • a rotational driving amount further required for the upper yarn pipe arm 36 to maintain the approach when the package 30 is lifted up (hereinafter, "rotational driving amount to be increased”) is calculated by using the grasped lift-up amount and a predetermined coefficient. Then, the upper yarn pipe arm 36 is pivoted by applying a driving amount calculated by adding the rotational driving amount to be increased to the reference rotational driving amount. As a result, even when the lift-up amount varies, the position of the package 30 surface can be tracked according to that lift-up amount, and the upper yarn suction port 35 can be moved to the position at the predetermined distance from the surface of the package 30.
  • the shutter of the upper yarn pipe arm 36 is opened and the suction current is generated in the upper yarn suction port 35.
  • the package driving motor 41 is controlled to start the reverse rotation of the package 30. Accordingly, the yarn end of the package 30 that is in the lift-up state and rotating reversely is caught by the upper yarn suction port 35 that is at the position at the predetermined distance from the surface of the package 30.
  • the upper yarn suction port 35 is moved toward the yarn joining position. Accordingly, the yarn end of the package 30 is guided to the yarn joining device 14, and the reverse rotation of the package 30 is slowed down and then stopped.
  • the yarn joining device 14 starts the yarn joining of the lower yarn caught by the lower yarn suction port 32 and the upper yarn caught by the upper yarn suction port 35. After the yarn joining is completed, the suction current that is flowing in the upper yarn suction port 35 is stopped by closing the shutter of the upper yarn pipe arm 36.
  • the lift-up amount may vary as shown in FIGS. 5A and 6A .
  • the upper yarn suction port 35 is moved based on the rotation angle of the cradle 23. Therefore, even when the lift-up amount varies, such variation can be tolerated (absorbed), and the upper yarn suction port 35 can be reliably moved to the position at the predetermined distance from the surface of the package 30 as shown in FIGS. 5B and 6B .
  • the upper yarn suction port 35 can come near the package 30 according to the lift-up amount, and an appropriate clearance with respect to the package 30 can be ensured. Because the lift-up amount is detected every time the lift-up is performed, effect of the variation in the lift-up amount can be suppressed. A yarn end finding position at which the yarn end of the package 30 is caught can be controlled more precisely. Therefore, according to the winder unit 10, the yarn end of the package 30 can be caught reliably. Thus, yarn end finding efficiency and time efficiency can be improved, and the production efficiency, too, can be improved.
  • the cradle 23 is pivotable around the pivoting shaft 48.
  • the air cylinder 60 causes the cradle 23 to pivot around the pivoting shaft 48 so as to move the package 30 between the position at which the package 30 is in contact with the contact roller 29 and the position at which the package 30 is separated from the contact roller 29.
  • the rotation angle of the cradle 23 is detected by the angle sensor 44. According to such a configuration, even if the lift-up amount varies, the lift-up amount can be accurately grasped based on the detection result of the angle sensor 44. Therefore, by causing the upper yarn suction port 35 to move based on the detection result of the angle sensor 44, the upper yarn suction port 35 can be reliably moved to the position at the predetermined distance from the surface of the package 30.
  • the air cylinder 60 is driven by the compressed air.
  • the responsiveness related to the lift-up can be increased.
  • variation in the lift-up amount tends to be significant, the effect explained above in which the yarn end of the package 30 can be reliably caught is particularly promising.
  • the winder unit 10 includes the package driving motor 41 that rotationally drives the package 30.
  • the unit controlling section 50 controls the package driving motor 41 so as to rotate the package 30 in the direction opposite to the winding direction. Accordingly, the yarn end of the package 30 can be caught more reliably.
  • the predetermined distance is changeably set by the setting section 91. Accordingly, the predetermined distance can be set and changed as desired.
  • the predetermined distance is a distance between the surface of the package 30 and the upper yarn suction port 35 that is lifted upward to perform sucking and catching. This distance can be stipulated as a minimum distance between any one end portion among the left and right end portions of the package 30 and an end portion of the upper yarn suction port 35 in the same orientation. Moreover, this distance can be stipulated as a minimum distance between a center of the package 30 in a width direction thereof and a center of the upper yarn suction port 35 in a width direction thereof.
  • an optical-type fixed length device can be omitted.
  • the above embodiments can include a warning section that outputs a warning based on the rotation angle detected by the angle sensor 44 in the separated state (the surface position information acquired by the surface position information acquiring section). For example, if the rotation angle detected by the angle sensor 44 is larger than an upper limit threshold, or is smaller than a lower limit threshold, the variation of the rotation angles detected by the angle sensor 44 exceeds a predetermined range, and the like, time-dependent change in the lift-up amount can be grasped. Accordingly, by outputting the warning in such a case, attention can be called to that time-dependent change. It becomes possible to determine whether wearing out is present or maintenance is needed in any component such as the air cylinder 60 and the like.
  • an alarm device and the like that outputs an alarm can be used as the warning section.
  • an alarm that indicates that the lift-up amount is insufficient can be generated.
  • a message for the warning section can also be displayed on the displaying section 92. In such a configuration, the displaying section 92 operates as the warning section.
  • the angle sensor 44 is included as the surface position information acquiring section; however, in addition to the angle sensor 44, the configuration can include a distance sensor that is arranged on the upper yarn suction port 35 and detects the distance up to the surface of the package 30 as the surface position information.
  • a distance sensor 81 which is an optical sensor and the like that emits light along an opening direction of the upper yarn suction port 35, is arranged on the upper yarn suction port 35 (in the figure, on a portion near the upper yarn suction port 35 of the upper yarn catching member 26).
  • the distance sensor 81 detects the distance up to the surface of the package 30, and acquires the position of the surface of the package 30.
  • the lift-up amount can be accurately grasped based on the detection result of the distance sensor 81.
  • the upper yarn suction port 35 By causing the upper yarn suction port 35 to move based on the detection result of the distance sensor 81, the upper yarn suction port 35 can be reliably moved to the position at the predetermined distance from the surface of the package 30.
  • the distance sensor is not particularly limited to a certain configuration, and various known distance sensors can be used.
  • the configuration in which the package 30 is moved by the air cylinder 60 is cited as an example.
  • a configuration in which the package 30 is moved by a hydraulic cylinder and the like can be used.
  • the unit controlling section 50 controls the generation of the suction current in the upper yarn suction port 35 and stopping thereof by controlling the opening / closing operation of the shutter; however, the shutter can always be in an open state. In such a configuration, for example, it becomes possible to simplify the control performed by the unit controlling section 50.
  • the package 30 is directly rotationally driven by the package driving motor 41; however, the contact roller 29 can be driven and the package 30 can be rotated following the rotation of the contact roller 29.
  • the method explained in the above embodiments to detect the diameter of the package 30 at the time of non-lift-up is not limited to such method, and the diameter of the package 30 can be detected by using methods cited as an example below.
  • a dedicated yarn speed sensor is arranged on the yarn traveling path to detect the traveling speed of the yarn 20.
  • a winding angle is calculated by the unit controlling section 50 based on the traveling speed and the traversing speed of the yarn 20, and the circumferential speed of the package 30 is calculated based on the winding angle and the traveling speed of the yarn 20.
  • the diameter of the package 30 can be calculated based on the rotational speed of the package 30 and the circumferential speed of the package 30.
  • the diameter of the package 30 can be calculated based on the total length of the yarn 20 that is wound on the package 30, the winding speed of the yarn 20, and the type of the yarn 20 (thickness and the like).
  • the package 30 at the time of the lift-up, after causing the package 30 to perform the reverse rotation at once, the package 30 can be caused to perform the normal rotation, or after the package 30 is caused to perform the normal rotation at once, the package 30 can be caused to perform the reverse rotation.
  • the package 30 at the time of the lift-up, for a predetermined set time period, the package 30 can be caused to perform the normal rotation or the reverse rotation at a rotational speed at which the yarn end of the package 30 can be pulled away. In such configurations, the yarn end can be easily pulled away from the package 30.
  • the setting section 91 can be arranged in the winder unit 10.
  • a yarn winding machine includes a holding section that rotatably holds a package; a contact section capable of contacting a surface of the package; a moving section capable of moving the package between a position at which the package is in contact with the contact section and a position at which the package is separated from the contact section; a yarn catching section capable of moving near or away from the surface of the package and catching a yarn end of the package; a surface position information acquiring section that acquires surface position information indicative of a position of the surface of the package; and a control section that controls a movement of the yarn catching section, and, in a separated state in which the package is separated from the contact section by the moving section, moves the yarn catching section near the surface of the package based on the surface position information acquired by the surface position information acquiring section so that a distance of the yarn catching section from the surface of the package is equal to a predetermined distance.
  • the yarn catching section is moved based on the acquired surface position information. Therefore, even if the lift-up amount varies, the variation can be tolerated and the yarn catching section can be reliably moved to a position at the predetermined distance from the surface of the package. Therefore, the yarn end of the package can be reliably caught.
  • the holding section includes a pivoting shaft and is pivotable around the pivoting shaft.
  • the moving section pivots the holding section around the pivoting shaft to move the package between the position at which the package is in contact with the contact section and the position at which the package is separated from the contact section.
  • the surface position information acquiring section is an angle sensor that detects a rotation angle of the holding section around the pivoting shaft as the surface position information.
  • the surface position information acquiring section can include a distance sensor that is attached to the yarn catching section and detects a distance thereof from the surface of the package as the surface position information.
  • the moving section can be driven by compressed air.
  • the variation in the lift-up amount tends to be significant. Therefore, the effect explained above in which the yarn end of the package is reliably caught is particularly promising in such a configuration.
  • the above yarn winding machine can include a package driving section that rotationally drives the package.
  • the control section can control the package driving section to rotate the package in a direction opposite to a winding direction when catching the yarn end of the package by using the yarn catching section in the separated state. With this configuration, the yarn end of the package can be more reliably caught.
  • the above yarn winding machine can include a warning section that outputs a warning based on the surface position information acquired by the surface position information acquiring section in the separated state. Based on the surface position information acquired by the surface position information acquiring section in the separated state, time-dependent change in the lift-up amount can be grasped. Therefore, by outputting a warning based on the surface position information acquired by the surface position information acquiring section in the separated state, attention can be called to that time-dependent change.
  • the above yarn winding machine can include a setting section for setting and changing the predetermined distance. With this configuration, the predetermined distance can be set and changed as desired.
