  • the present invention relates to a winding device and a winding system including the winding device.
  • Patent Literature 1 Japanese Laid-Open Patent Publication No. 2011-47074 discloses a false-twist texturing machine configured to perform false twisting of a yarn.
  • the false-twist texturing machine of Patent Literature 1 includes a yarn supplying unit configured to supply a yarn, a winding device configured to perform winding of the yarn, a heater provided on a yarn path from the yarn supplying unit to the winding device, a cooler, and a false-twisting device.
  • the winding device includes a cradle which rotatably supports a bobbin holder, and is configured to form a package by winding the yarn onto a bobbin attached to the bobbin holder.
  • Patent Literature 2 discloses a winding device including (i) a stocker (an empty bobbin supply path in Patent Literature 2) which stores empty bobbins supplied to a cradle and (ii) a package storage unit (a package tray in Patent Literature 2) which stores fully-wound packages taken out from the cradle. After one fully-wound package is detached from the cradle and sent to the package storage unit, one empty bobbin stored in the stocker is supplied to the cradle. As a result, the replacement of a bobbin is completed.
  • both of the stocker and the package storage unit are provided on one side of the cradle in a direction orthogonal to the axial direction of a bobbin holder.
  • the stocker is provided above the package storage unit.
  • winding devices are aligned to form plural stages in the vertical direction.
  • the larger the number of these stages is, the larger the height of the entire false-twist texturing machine is.
  • stockers and packages storage unit of the winding devices are provided above the winding devices aligned to form the stages so that it is difficult for an operator to replenish the stocker with empty bobbins and to take each fully-wound package out from the package storage unit.
  • An object of the present invention is to suppress the increase of height in a winding device.
  • a winding device of the present invention includes: a cradle which is able to rotatably support a bobbin holder and which is movable between a winding start position and a release position, formation of at least one package starting at the winding start position by winding a yarn on at least one bobbin attached to the bobbin holder, the at least one package being released from the bobbin holder at the release position; a package storage unit configured to store the at least one package released from the cradle at the release position; a stocker which has a first supporting surface and which is configured to store the at least one bobbin supplied to the cradle, the first supporting surface supporting the at least one bobbin from below; and a contact roller which rotates while being in contact with an outer circumferential surface of the at least one package, the stocker being provided on one side of a vertical plane passing an axial center of the bobbin holder supported by the cradle at the release position, the package storage unit being provided on the other side of the vertical
  • the stocker is provided on the one side of the vertical plane passing the axial center of the bobbin holder supported by the cradle at the release position.
  • the package storage unit is provided on the other side of the vertical plane.
  • the first supporting surface of the stocker is below the upper end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position, and the rotational center of the contact roller whose position is lower than that of the stocker is above the lower end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position. It is therefore possible to suppress the increase of height of the winding device, without preventing the fully-wound package from being sent to the package storage unit.
  • the stocker is able to store bobbins, and an upper end of each of at least one of the bobbins stored in the stocker is, in the vertical direction, below the upper end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position.
  • a large part of the stocker is below the upper end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position. It is therefore possible to further suppress the increase of height of the winding device.
  • the cradle is movable between the winding start position and the release position by swinging about a swing axis extending in an axial direction of the bobbin holder
  • the package storage unit includes a second supporting surface which supports, from below, the at least one package which is released from the cradle, and the second supporting surface is, in the vertical direction, above the swing axis and below a center of the at least one package supported by the cradle at the release position.
  • the second supporting surface of the package storage unit is above the swing axis of the cradle and below the center of the at least one package supported by the cradle at the release position. It is therefore possible to suppress the increase of height of the winding device due to the package storage unit.
  • the second supporting surface is above the lower end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position in the vertical direction.
  • the position of the second supporting surface of the package storage unit is arranged to be as high as possible within a range lower than the center of the package supported by the cradle at the release position. It is therefore possible to further suppress the increase of height of the winding device due to the package storage unit.
  • the package storage unit includes a second supporting surface which supports, from below, the at least one package which is released from the cradle, and the second supporting surface is, in the vertical direction, above the lower end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position and below a center of the at least one package supported by the cradle at the release position.
  • the second supporting surface of the package storage unit is above the lower end of the virtual maximum circumferential surface of the at least one package supported by the cradle at the release position and below the center of the at least one package supported by the cradle at the release position. It is therefore possible to suppress the increase of height of the winding device due to the package storage unit.
  • the winding device of the present invention further includes a bobbin supplying unit configured to supply each of the bobbins from the stocker to the cradle.
  • the bobbin supplying unit configured to supply the cradle with each of the bobbins stored in the stocker is provided to be independent from the stocker. It is therefore possible to suppress the increase of height of the winding device as compared to the case where the entire stocker swings.
  • the package storage unit is able to store packages and is inclined downward in a direction away from the vertical plane.
  • each of the packages is sent in order in the direction away from the vertical plane along the inclined package storage unit. It is therefore unnecessary to provide a device for sending, in order to store the packages in the package storage unit, each of the packages in the direction away from the vertical plane. As a result, the increase of height of the winding device is suppressed.
  • a winding system of the present invention is structured so that winding devices each of which is identical with the above-described winding device of the present invention are aligned to form plural stages in the vertical direction.
  • the increase of height of each of the winding devices provided to form the stages in the vertical direction is suppressed. Therefore, the increase of height from the highest one of the stages to the lowest one of the stages is also suppressed. This allows an operator to easily access stockers and package storage units of some winding devices provided at a high position in the vertical direction. Because of this, the operator easily replenishes each stocker with an empty bobbin and takes a fully-wound package out from each package storage unit.

  • the stocker 60 is able to store plural bobbins Bw.
  • at least one upper end of at least one bobbin Bw stored in the stocker 60 is below the upper end t1 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position.
  • a large part of the stocker 60 is below the upper end t1 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position. It is therefore possible to further suppress the increase of height of the winding device 21.
  • the cradle arms 30 are movable between the winding start position and the release position by swinging about the swing axis 31.
  • the package storage unit 50 includes the second supporting surfaces 51 which support each wound package Pw, which is released from the cradle arms 30, from below. In the vertical direction, the second supporting surfaces 51 are above the lower end t2 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position and below the center x1 of the wound package Pw supported by the cradle arms 30 at the release position.
  • the position of the second supporting surfaces 51 is arranged to be as high as possible within a range lower than the center x1 of the wound package Pw supported by the cradle arms 30 at the release position. It is therefore possible to further suppress the increase of height of the winding device 21 due to the package storage unit 50.
  • the winding device 21 of the present embodiment further includes the bobbin supplying unit 80 configured to supply each bobbin Bw to the cradle arms 30 from the stocker 60.
  • the bobbin supplying unit 80 configured to supply each bobbin Bw to the cradle arms 30 from the stocker 60.
  • each bobbin Bw is supplied to the cradle arms 30 in such a way that the entire stocker 60 swings about a rotational axis extending in the axial direction of the bobbin holder 70, the stocker 60 passes above where the stocker 60 was.
  • a space for allowing the stocker 60 to swing needs to be provided above the winding device 21. This increases the actual height of the winding device 21.
  • the bobbin supplying unit 80 configured to supply the cradle arms 30 with each bobbin Bw stored in the stocker 60 is provided to be independent from the stocker 60. It is therefore possible to suppress the increase of height of the winding device 21 as compared to the case where the entire stocker 60 swings.
  • the package storage unit 50 is able to store plural wound packages Pw and is inclined downward in a direction away from the vertical plane F and in the base width direction. With this arrangement, even when plural wound packages Pw are released from the cradle arms 30 and sent to the package storage unit 50, each wound package Pw is sent in order in the direction away from the vertical plane F and in the base width direction along the inclined package storage unit 50. It is therefore unnecessary to provide a device for sending, in order to store these wound packages Pw in the package storage unit 50, each wound package Pw in the direction away from the vertical plane F and in the base width direction. As a result, the increase of height of the winding device 21 is suppressed.
  • the winding devices 21 are provided to form four stages in the vertical direction.
  • the increase of height of each of the winding devices 21 provided to form four stages in the vertical direction is suppressed. Therefore, the increase of height from winding devices 21 on the highest stage to winding devices 21 on the lowest stage is also suppressed.
  • This allows an operator to easily access the stockers 60 and package storage units 50 of winding devices 21 provided at a high position in the vertical direction. Because of this, the operator easily replenishes each stocker 60 with empty bobbins Bw and takes fully-wound packages Pw out from each package storage unit 50.
  • At least one upper end of at least one of plural bobbins Bw stored in the stocker 60 is below the upper end t1 of the virtual maximum circumferential surface of a wound package Pw supported by the cradle arms 30 at the release position.
  • upper ends of all bobbins Bw stored in the stocker 60 may be above the upper end t1 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position.
  • the first supporting surface 61 is below the upper end t1 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position.
  • each bobbin Bw stored in the stocker 60 is supplied to the cradle arms 30 in such a way that the arm member 63 of the bobbin supplying unit 80 rotates about the rotational axis 62 together with the bobbin supporter 64.
  • each winding device 21 may not include the bobbin supplying unit 80.
  • each bobbin Bw stored in the stocker 60 may be supplied to the cradle arms 30 in such a way that the entire stocker 60 swings downward about a rotational axis which is provided at a lower portion of the stocker 60 and which extends in the axial direction of the bobbin holder 70.
  • the stocker 60 may not move and each bobbin Bw may be received from the stocker 60 in such a way that the cradle arms 30 rotate about the swing axis 31.
  • the second supporting surfaces 51 are above the lower end t2 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position.
  • the second supporting surfaces 51 may be below the lower end t2 of the virtual maximum circumferential surface of the wound package Pw supported by the cradle arms 30 at the release position.
  • the second supporting surfaces 51 are preferably above the swing axis 31 of the cradle arms 30.
  • the cradle arms 30 are movable between the winding start position and the release position by swinging about the swing axis 31.
  • the cradle arms 30 may move between the winding start position and the release position in a different manner.
  • the cradle arms 30 may be moved along unillustrated rails.
  • the position of the stocker 60 is higher than that of the package storage unit 50 in the vertical direction.
  • the position of the stocker 60 may be lower than that of the package storage unit 50 in the vertical direction.
  • the winding device 21 is applied to the false-twist texturing machine 1.
  • the winding device 21 of the present invention is applicable not only to the false-twist texturing machine 1 but also to a re-winder.
  • the winding devices 21 of the embodiment above are provided to form four stages in the vertical direction. However, the winding devices 21 may be provided to form two or three stages, five or more stages, or one stage in the vertical direction. In the embodiment above, the winding devices 21 of the false-twist texturing machine 1 are aligned to form pleural stages in the vertical direction. However, winding devices of other textile machines such as re-winders may be provided to form plural stages in the vertical direction.
