Definitions

  • the present invention relates to a spun yarn take-up apparatus including a yarn winding device that winds a yarn onto a bobbin.
  • a plurality of spun yarn take-up apparatuses each of which includes a yarn winding device for winding a yarn onto bobbins that are attached to a bobbin holder configured to allow the bobbins to be attached and removed from the leading end thereof, a godet roller located upstream of the yarn winding device, and the like, are installed side by side horizontally in a plane orthogonal to the axial direction of the bobbin holder; neighboring two of the spun yarn take-up apparatuses are paired such that corresponding one side surfaces of the two spun yarn take-up apparatuses are arranged opposed to each other with a narrow gap therebetween.
  • Such pairs of spun yarn take-up apparatuses are aligned at intervals horizontally in the plane orthogonal to the axial direction of the bobbin holder.
  • the godet roller whose rotation axis extends in a direction orthogonal to a bobbin holder shaft of the yarn winding device is arranged above the yarn winding device.
  • a space for the yarn threading operation is ensured on the opposite side-surface side of each yarn winding device which is opposite to the one side surface thereof.
  • An operator on a working platform arranged in this space, performs the yarn threading operation onto the godet roller of the spun yarn take-up apparatus.
  • the godet roller such that the rotation axis thereof extends in parallel with the bobbin holder shaft and additionally rollers including the godet roller are placed on the leading end side of the yarn winding device at a time of the yarn threading operation, thereby allowing the operator to perform the yarn threading operation onto the rollers from the leading end side of the bobbin holder of the yarn winding device.
  • the operator is able to perform the yarn threading operation onto the rollers including the godet roller, while being in a space on the leading end side of the bobbin holder, which is intended for attachment and removal of bobbins to and from the bobbin holder. Accordingly, it is not necessary to separately ensure a space for the yarn threading operation.
  • the space required for installation of the spun yarn take-up apparatus can be reduced.
  • the working platform on which the operator performs the yarn threading operation is arranged on the leading end side of the bobbin holder. Therefore, when attachment and removal of bobbins are performed from the leading end of the bobbin holder, the working platform may be an obstruction.
  • Providing a common working platform that is shared among a plurality of spun yarn take-up apparatuses and configuring this working platform to be movable across the plurality of spun yarn take-up apparatuses enables the working platform to be retracted to a position in which the working platform does not obstruct the attachment and removal of bobbins.
  • this makes it necessary to, for example, lay a rail for allowing the working platform to move, which results in a complicated apparatus structure.
  • An object of the present invention is to provide a spun yarn take-up apparatus configured to prevent a working platform used for performing a yarn threading operation onto each roller from being an obstruction in attachment and removal of bobbins to and from a bobbin holder of a yarn winding device even in a case where a godet roller is arranged in parallel with the bobbin holder and arranged on the leading end side of the yarn winding device.
  • a first invention provides a spun yarn take-up apparatus including: a yarn winding device including a bobbin holder that has a winding spindle extending in a horizontal direction and that allows a bobbin to be attached and removed from a leading end of the bobbin holder, the yarn winding device being configured to form a package by winding a yarn onto a bobbin attached to the bobbin holder; a plurality of godet rollers arranged above the yarn winding device, and configured to take up a yarn discharged from a spinning machine, draw the yarn, and then feed the yarn to the yarn winding device; and a working platform used for performing a yarn threading operation onto at least one of the plurality of godet rollers, the working platform being not shared with another spun yarn take-up apparatus.
  • the plurality of godet rollers have rotation axes thereof extending in parallel with an axial direction of the winding spindle.
  • the working platform is configured to selectively take an operation posture and a retracted posture.
  • the working platform taking the operation posture is located on a leading end side of the bobbin holder relative to the bobbin holder with respect to the axial direction of the winding spindle.
  • the operation posture is taken when the yarn threading operation is performed.
  • the working platform taking the retracted posture is distant from the bobbin holder.
  • the working platform can selectively take either one of the operation posture and the retracted posture. Accordingly, putting the working platform into the operation posture allows the yarn threading operation onto the godet rollers to be performed by using the working platform, while putting the working platform into the retracted posture can prevent the working platform from being an obstruction in attachment and removal of the bobbin.
  • a second invention provides a spun yarn take-up apparatus that is the spun yarn take-up apparatus according to the first invention, in which: when the working platform takes the operation posture, the working platform overlaps the package with respect to an orthogonal plane orthogonal to the axial direction of the winding spindle; and when the working platform takes the retracted posture, the working platform does not overlap the package with respect to the orthogonal plane.
  • the second invention exerts the following effect. That is, in a case where the working platform taking the operation posture overlaps the package with respect to the orthogonal plane, the working platform may be an obstruction particularly in attachment and removal of the bobbin to and from the bobbin holder. In such a case, however, putting the working platform into the retracted posture can prevent the working platform from being an obstruction in attachment and removal of the bobbin to and from the bobbin holder.
  • a third invention provides a spun yarn take-up apparatus that is the spun yarn take-up apparatus according to the first or second invention, in which: the working platform includes a footboard swingably supported on a swing shaft extending in parallel with the axial direction of the winding spindle, the swing shaft being arranged in a position that is deviated from the bobbin holder with respect to an orthogonal plane orthogonal to the axial direction of the winding spindle; when the operation posture is taken, the footboard is arranged to extend in a horizontal direction; and when the retracted posture is taken, the footboard is arranged to be inclined relative to a horizontal plane so that a horizontal length of the footboard with respect to the orthogonal plane is shorter than when the operation posture is taken.
  • the horizontal length of the working platform with respect to the orthogonal plane is shorter in the retracted posture than in the operation posture. Accordingly, enabling the working platform to selectively take either one of the operation posture and the retracted posture can suppress a size increase in the spun yarn take-up apparatus with respect to the horizontal direction within the orthogonal plane.
  • a fourth invention provides a spun yarn take-up apparatus that is the spun yarn take-up apparatus according to the third invention, further including: a storage for storing the working platform, the storage being provided in a position deviated from the bobbin holder in a direction within the orthogonal plane; and a slidable component having the swing shaft provided thereon, the slidable component being configured to move in the axial direction of the winding spindle and thereby allow a portion thereof to which the swing shaft is attached to enter and exit the storage.
  • the working platform is able to be stored into the storage by, under a state where the working platform takes the retracted posture, the slidable component being moved in the axial direction of the winding spindle until the portion to which the swing shaft is attached is received into the storage.
  • the working platform can be stored in the storage that is provided in the position deviated from the bobbin holder in the direction within the orthogonal plane. Additionally, the working platform is stored in the storage while taking the retracted posture in which the horizontal length of the working platform with respect to the orthogonal plane is shortened. Therefore, the horizontal length (width) of the storage with respect to the orthogonal plane is not so long. Accordingly, providing the storage can suppress a size increase in the spun yarn take-up apparatus.
  • a fifth invention provides a spun yarn take-up apparatus that is the spun yarn take-up apparatus according to the fourth invention, in which a wall of the storage on the bobbin holder side with respect to the orthogonal plane extends farther to the leading end side of the bobbin holder with respect to the axial direction of the winding spindle than the bobbin holder does.
  • the wall of the storage on the bobbin holder side with respect to the orthogonal plane extends further to the leading end side of the bobbin holder with respect to the axial direction of the winding spindle than the bobbin holder does. Accordingly, at a time of pulling out the working platform from the storage, until a portion of the slidable component to which the working platform is attached comes to a position farther to the leading end side of the bobbin holder in the axial direction of the winding spindle than the bobbin holder does, the footboard is not swingable beyond the wall of the storage toward the operation posture (toward the side closer to the bobbin holder). This can prevent the working platform from interfering with the bobbin holder in the course of the pull-out of the working platform from the storage into the operation posture.
  • the working platform can selectively take either one of the operation posture and the retracted posture. Accordingly, putting the working platform into the operation posture allows the yarn threading operation onto each roller to be performed by using the working platform, while putting the working platform into the retracted posture can prevent the working platform from being an obstruction in attachment and removal of the bobbin.

  • the operator W resting on the upper surface of the footboard 41, performs the yarn threading operation.
  • the footboards 41 and 42 and the leg portions 43 to 45 are swung in the manner opposite to that described above.
  • the working platform 33 taking the operation posture as shown in FIGS. 5 , 6 , and 7C is put into the retracted posture as shown in FIGS. 4 and 7B , and then the slidable component 32 is moved toward the base end side in the winding axis direction.
  • the slidable component 32 and the working platform 33 are stored in the storage space 31 a of the storage 31.
  • the operator W is not necessary that the operator W is constantly on the working platform during the whole of the yarn threading operation performed onto the godet rollers 21 to 24 and the guide rollers 11, 12, 17, and 18. Instead, it may be acceptable that, when performing the yarn threading operation onto part of the rollers, the operator W climbs down the working platform 33 and stands on a floor, as appropriate.
  • the above-described embodiment enables the yarn threading operation onto the godet rollers 21 to 24 and the guide rollers 11, 12, 17, and 18 to be performed in the working space S which is intended for attachment and removal of the bobbins B to and from the bobbin holder 7. Therefore, a space intended for the yarn threading operation does not have to be ensured between neighboring spun yarn take-up machines 1. Accordingly, a space required for installation of the spun yarn take-up machine 1 is reduced.
  • yarn threading is also performed onto, for example, the plurality of fulcrum guides 13 and the plurality of traverse guides 8 aligned in the winding axis direction.
  • the yarn threading onto them can be automatically performed by using a well-known yarn threading device (for example, see Japanese Patent Application Laid-Open Nos. 2008-297078 and 2011-102174 ).
  • the yarns Y threaded onto the godet rollers 21 to 24 do not run back and forth between the rollers. Therefore, a range where the yarns Y are threaded is not so long in the axial direction of the godet rollers 21 to 24.
  • the operator W on the working platform 33 (footboard 41) can readily perform the yarn threading operation.
  • the working platform 33 used for the yarn threading operation is able to selectively take either one of the operation posture and the retracted posture described above. Accordingly, putting the working platform 33 into the operation posture allows the yarn threading operation to be performed, while putting the working platform 33 into the retracted posture can prevent the working platform 33 from being an obstruction in attachment and removal of the bobbins B to and from the bobbin holder 7.
  • the working platform 33 is provided individually for each of the spun yarn take-up machines 1. This makes it possible to simultaneously perform the yarn threading operation in the plurality of spun yarn take-up machines 1.
  • the footboards 41 and 42 when the working platform 33 takes the operation posture, the footboards 41 and 42 extend in the horizontal direction, while when the working platform 33 takes the retracted posture, the footboards 41 and 42 extend in the vertical direction and therefore the length thereof with respect to the alignment direction is smaller than in the operation posture. Accordingly, enabling the working platform 33 to selectively take either one of the operation posture and the retracted posture can suppress a size increase in the spun yarn take-up machine 1 with respect to the alignment direction.
  • the working platform 33 can be stored in the storage space 31a of the storage 31 which is provided in the position deviated from the yarn winding device 3 in the alignment direction. Additionally, as described above, the length of the working platform 33 taking the retracted posture is short with respect to the alignment direction. Therefore, providing the storage 31 in the position deviated from the yarn winding device 3 in the alignment direction can suppress a size increase in the spun yarn take-up machine 1.
  • the wall 31b of the storage 31 on the yarn winding device 3 side extends farther to the leading end side in the winding axis direction than the bobbin holder 7 does. Accordingly, at a time of pulling out the slidable component 32 and the working platform 33 from the storage 31, until the working platform 33 comes to a position farther to the leading end side in the winding axis direction than the bobbin holder 7 does, the vertically extending footboards 41 and 42 of the working platform 33 taking the retracted posture is restricted from falling over into a horizontal state by the wall 31b of the storage 31. This can prevent the footboards 41 and 42 from falling over and interfering with the bobbin holder 7 in the course of the pull-out of the slidable component 32 and the working platform 33.
  • the storage 31 and the slidable component 32 are provided individually for each of the spun yarn take-up machines 1, this is not limiting.
  • two neighboring spun yarn take-up machines 1 are configured symmetrically to each other in the alignment direction, and the storage 31 and the slidable component 32 are arranged between the two spun yarn take-up machines 1 and fixed to the pillars 14a of the spun yarn take-up machines 1.
  • the same working platform 33 as the above-described one is provided to each of the surfaces of the slidable component 32 with respect to the alignment direction.
  • one storage 31 and one slidable component 32 are shared between two spun yarn take-up machines 1, which can reduce the number of component parts of the apparatus.
  • the working platform 33 is provided individually for each of the spun yarn take-up machines 1, and therefore it is possible to simultaneously perform the yarn threading operation in the plurality of spun yarn take-up machines 1.
  • the wall 31b of the storage 31 on the yarn winding device 3 side extends farther to the leading end side in the winding axis direction than the bobbin holder 7 does.
  • this is not limiting, and it may be acceptable that the wall 31b extends merely to a position located on the base end side in the winding axis direction relative to the leading end of the bobbin holder 7.
  • occurrence of interference of the working platform 33 with the bobbin holder 7 can be prevented by, for example, enabling the working platform 33 to be fixed to the slidable component 32 when the retracted posture is taken and, after the pull-out of the slidable component 32 is completed, unfixing the working platform 33 so that the working platform 33 takes the operation posture.
  • the slidable component 32 having the working platform 33 attached thereto is moved in the winding axis direction, and thereby the working platform 33 is storable in the storage space 31a of the storage 31.
  • the working platform 33 may not be storable.
  • a plate-like member fixed to the frame 14 is arranged in the same position as the position where the slidable component 32 locates when pulled out from the storage 31 (that is, in the same position as the position of the slidable component 32 shown in FIGS. 4 and 7B ), and the working platform 33 is attached to this plate-like member.
  • putting the working platform 33 into the retracted posture avoids overlap between the working platform 33 and the packages P with respect to the winding axis direction, and therefore can prevent the working platform 33 from being an obstruction in attachment and removal of the bobbins B to and from the bobbin holder 7.
  • enabling the working platform 33 to be fixed to the above-mentioned plate-like member while taking the retracted posture can prevent the footboards 41 and 42 from falling over and thus putting the working platform 33 into the operation posture at a time of, for example, attaching and removing the bobbins B to and from the bobbin holder 7.
  • the working platform 33 includes the footboards 41 and 42 and the leg portions 43 to 45, and is configured such that the footboards 41 and 42 extend in the horizontal direction when the operation posture is taken while the footboards 41 and 42 extend in the vertical direction when the retracted posture is taken.
  • this is not limiting.
  • the working platform 33 may be configured to be movable in the alignment direction while keeping a state where the footboards 41 and 42 extend in the horizontal direction.
  • the working platform 33 overlaps the packages P with respect to the alignment direction when the working platform 33 takes the operation posture.
  • the working platform 33 may be located in a position deviated from the packages P with respect to the alignment direction when the working platform 33 takes the operation posture.
  • the working platform 33 when taking the operation posture, is located in a position that is on the leading end side in the winding axis direction relative to the bobbin holder 7 and closer to the bobbin holder 7 with respect to the alignment direction.
  • the working platform 33 may undesirably obstruct, for example, an operator performing the operation of attaching and removing the bobbins B to and from the bobbin holder 7. Therefore, putting the working platform 33 into the retracted posture can prevent the working platform 33 from being an obstruction in attachment and removal of the bobbins B to and from the bobbin holder 7.
  • the working platform 33 when the working platform 33 takes the retracted posture, the working platform 33 is located in a position retracted from its position in the operation posture in the alignment direction.
  • a working platform is movable up and down, so that the working platform is vertically retracted from its position in the operation posture by being moved to a position below the packages P such as a position under the floor on which the spun yarn take-up machine 1 is installed, or by being moved to a position above the packages P.
  • the posture of the working platform located below or above the packages P corresponds to the retracted posture according to the present invention.
  • one spun yarn take-up machine 1 includes the yarn winding device 3 having two winding units 3a and 3b.
  • the present invention is applicable to a spun yarn take-up apparatus including a yarn winding device having either one of the winding units 3a and 3b or to a spun yarn take-up apparatus including a yarn winding device having three or more winding units.
  • winding units 3a and 3b may be provided as a single winding unit by forming their main body frames 5 as one piece or connecting their main body frames 5 into an integrated body.
  • parts of the component members such as a driving unit (not shown) for driving the turret 6 and a controller (not shown), may be shared.
