  • Step S104 sets the state of the tension applying device 31 to the tension released state (Step S104, see FIG. 4A ). That is, the unit controller 15 sets the state of the tension applying device 31 to the tension released state before the holding section 32c that has caught the first yarn Y1 is moved to the second position (Step S105 explained later). Step S104 can be performed before or at the same time as Step S103.
  • the unit controller 15 rotates the arm 32b by controlling the arm driving motor 32d, thereby moving the holding section 32c above the tension applying device 31 (Step S105, see FIG. 6B ).
  • the position (second position) of the holding section 32c shown in FIG. 6B is a position opposing the first position with the tension applying device 31 interposed therebetween in the up-down direction. Accordingly, the first yarn Y1 is guided to the tension applying device 31. More specifically, the first yarn Y1 is arranged between the fixed gate members 31a and the movable gate members 31b in the horizontal direction (shown by a double-dashed line in FIG. 4A ).
  • the unit controller 15 controls the tension applying device 31 to switch the movable gate members 31b from the tension released state to the tension applied state (Step S106, see FIG. 4B ).

  • the first yarn Y1 is held by the fixed gate members 31a and the movable gate members 31b (in other words, the first yarn Y1 is introduced into the tension applying device 31).
  • the fixed gate members 31a and the movable gate members 31b apply resistance to the first yarn Y1.

  • the unit controller 15 When the operation button 51b is in the on state, the unit controller 15 reverses the rotation shaft of the package driving motor 43 at a predetermined rotation speed, drives the contact roller 42 in reverse, and rotates the package P in reverse. For example, as long as the operator continues to press the operation button 51b with his finger (see FIG. 7A ), the operation button 51b will remain on. Accordingly, the package driving motor 43 continues to run and the package P continues to rotate in reverse as long as the operator keeps pressing the operation button 51b with a finger. Therefore, the second yarn Y2 can be easily pulled out from the package P without requiring the second yarn Y2 to be pulled strongly (see FIG. 7B ).
  • the unit controller 15 stops the package driving motor 43.
  • the operation in which the operator presses the operation button 51b with his finger is the first operation to start the reverse operation of the package driving motor 43.
  • the operation in which the operator releases his finger from the operation button 51b is the second operation for stopping the reverse operation of the package driving motor 43.
  • the operator joins the first yarn Y1 and the second yarn Y2 by using the yarn joining device 100 (see FIG. 3 ). Finally, the operator presses the restart switch 53 (see FIG. 2 ). Accordingly, the stopped winding process is resumed.
  • the unit controller 15 sets the state of the tension applying device 31 to the tension released state before the holding section 32c that has caught the first yarn Y1 is moved to the second position. Moreover, the unit controller 15 switches the state of the tension applying device 31 from the tension released state to the tension applied state before the holding section 32c that has caught the first yarn Y1 is moved from the second position. Accordingly, the first yarn Y1 can be reliably guided to the tension applying device 31. Moreover, it is possible to prevent the first yarn Y1 from falling off the tension applying device 31 after the first yarn Y1 is guided to the tension applying device 31.
  • the unit controller 15 operates the package driving motor 43 to rotate the package P in a reverse direction when the operation panel 14 is operated in a state in which the yarn Y is disconnected into the first yarn Y1 and the second yarn Y2. In such a way, by operating the operation panel 14, the second yarn Y2 can be easily pulled while controlling the labor and / or damage done to the package P.
  • the unit controller 15 continues to operate the package driving motor 43 from the time the operation button 51b is pressed until the operator releases his finger from the operation button 51b (that is, from the time the first operation is performed until the second operation is performed). With such a process, the second yarn Y2 of an arbitrary length can be pulled out depending on the operation performed by the operator.
  • a yarn winding device is configured to form a package by winding a yarn that is pulled from a yarn feeder.
  • the yarn winding device includes a tension applying device that applies tension to the yarn running towards the package side in a yarn running direction; a holding section that holds a first yarn when the yarn is disconnected into the first yarn on the yarn feeder side in the yarn running direction and a second yarn on the package side in the yarn running direction; a movement driving section that drives and moves the holding section between a first position where the first yarn can be caught and a second position where the first yarn can be introduced into the tension applying device; and a control section that controls the movement driving section to move the holding section from the first position to the second position while the first yarn is held in the holding section, and then return and stop the holding section at the first position, or stop the holding section at a third position on the way back to the first position.
  • the holding section by moving the holding section from the first position to the second position, the first yarn can be introduced into the tension applying device. Accordingly, with such a configuration, the time and effort of the operator can be reduced compared to the case in which the operator introduces the first yarn into the tension applying device. Furthermore, the holding section can be stopped at the first position or the third position so that the first yarn can be easily pulled from the holding section. As explained above, the preparatory operation before joining the first yarn and the second yarn can be made easier in the yarn winding device where the first yarn and the second yarn need to be joined by the operator.
  • control section controls, when the direction along the yarn running from the yarn feeder to the tension applying device is the first direction, the movement driving section to stop the holding section at the third position, which is a position that is more towards the working space, which is a space where the yarn end of the first yarn and the yarn end of the second yarn can be joined, than the first position and the second position.
  • the control section controls, when the direction along the yarn running from the yarn feeder to the tension applying device is the first direction, the movement driving section to stop the holding section at the third position, which is a position that is more towards the working space, which is a space where the yarn end of the first yarn and the yarn end of the second yarn can be joined, than the first position and the second position.
  • the yarn end of the first yarn and the yarn end of the second yarn are joined manually at the third position by an operator. Therefore, the yarn joining work can be performed at a position that is easy for the operator to handle.
  • the tension applying device is switchable between a tension released state in which the first yarn held by the holding section can be introduced, and a resistance applied state in which resistance can be applied to the first yarn that is introduced by the holding section.
  • the control section sets the state of the tension applying device to the tension released state before moving the holding section that holds the first yarn to the second position, and switches the state of the tension applying device from the tension released state to the resistance applied state before moving the holding section, which is holding the first yarn, from the second position.
  • the resistance can be applied to the first yarn after the first yarn is guided to the tension applying device. Therefore, it is possible to prevent the first yarn from falling off the tension applying device.
  • the above yarn winding device includes a package supporting section that rotatably supports the package; a package driving section capable of rotating the package in a direction opposite to the direction in which the yarn is wound; and an operation panel that can be operated by an operator.
  • the control section operates the package driving section when the operation panel is operated when the yarn is disconnected into the first yarn and the second yarn.
  • the second yarn When pulling out the second yarn from the package to join the first yarn and the second yarn, if the yarn is thin and / or the package is heavy (that is, the package is difficult to rotate as the inertial mass is large), pulling the yarn by the operator may cause the yarn to be broken off as the yarn may not be able to withstand the tensile stress. On the other hand, if the operator manually rotates the package in the reverse direction to prevent this from occurring, it takes time and effort, and may also damage the yarn on the surface of the package. In this regard, in the present invention, by operating the operation panel, the second yarn can be easily pulled while controlling the labor and / or damage done to the package.
  • control section continues to operate the package driving section from when the first operation to start the operation of the package driving section is performed until the second operation to end the operation of the package driving section is performed.
  • the second yarn of an arbitrary length can be pulled out depending on the operation by the operator.
  • the control section operates the package driving section for a predetermined time period each time the predetermined operation to operate the package driving section is performed once.
  • the second yarn that has a predetermined length can be pulled. Accordingly, by configuring an appropriate setting beforehand, the second yarn having an appropriate length can be pulled with a simple operation.
  • a yarn joining method is used in a yarn winding device including a tension applying device that applies tension to a yarn running towards a package side in a yarn running direction; a holding section that holds a first yarn when the yarn is disconnected into the first yarn on a yarn feeder side in the yarn running direction and a second yarn on the package side in the yarn running direction; a movement driving section that drives and moves the holding section between a first position where the first yarn can be caught and a second position where the first yarn can be introduced into the tension applying device; and a control section.
  • the yarn joining method includes a first step at which the control section controls the holding section to hold the first yarn; a second step at which the control section controls the movement driving section to move the holding section from the first position to the second position; and a third step at which the control section provides control to return the holding section to the first position and stop there, or, stop the holding section at a third position on the way back to the first position, so that joining of the yarn can be performed by an operator. Accordingly, the operator can perform the yarn joining efficiently.
