Definitions

  • the present invention relates to a yarn winder including a contact roller applying a contact pressure to a package.
  • Patent Literature 1 recites a yarn winder which is configured to wind yarns.
  • the winder includes a bobbin holder which extends in the front-rear direction and to which bobbins are attached to be lined up, a traverse unit provided above the bobbin holder to traverse yarns, and a contact roller which extends in the axial direction of the bobbin holder and is configured to apply a contact pressure to each of packages formed by winding yarns onto the bobbins.
  • the contact roller extends along the front-rear direction and is rotatably supported by a roller supporting member.
  • the roller supporting member includes two arm portions (hereinafter, supporting portions) which rotatably support end portions in the front-rear direction of the contact roller and extend radially outward from the radial center of the contact roller.
  • the two supporting portions are connected to each other by a plate-shaped portion (hereinafter, plate member) which extends along the front-rear direction.
  • plate member When viewed in the front-rear direction, the plate member overlaps the supporting portions and is sandwiched between the bobbin holder and the traverse unit.
  • the contact roller and the roller supporting member are also elongated in the front-rear direction accordingly.
  • the bending rigidity of the roller supporting member is decreased in the front-rear direction, and this may cause problems such as vibrations generated by the driving of the yarn winder.
  • the cross-sectional area of the plate member in the direction orthogonal to the front-rear direction may be increased.
  • the plate member is sandwiched between the bobbin holder and the traverse unit. On this account, it is necessary to relocate the bobbin holder and the traverse unit to create a space, when the cross-sectional area of the plate member is increased. This causes increase in the size of the yarn winder.
  • An object of the present invention is to improve the rigidity of a roller supporting member while restraining an apparatus from being increased in size.
  • a yarn winder includes: a bobbin holder which extends in a predetermined longitudinal direction, bobbins on which yarns are wound, respectively, being attached to the bobbin holder to be lined up in the longitudinal direction; a traverse unit which is configured to traverse the yarns; a contact roller which extends in the longitudinal direction and is configured to apply a contact pressure to packages which are formed by winding, onto the bobbins, the yarns having been traversed by the traverse unit; and a roller supporting member which supports the contact roller to be rotatable, the roller supporting member including: supporting portions which rotatably support at least end portions in the longitudinal direction of the contact roller and extend at least radially outward from a radial central portion of the contact roller; and a rigidity improving member which extends in the longitudinal direction and to which the supporting portions are fixed, the rigidity improving member being provided so as not to overlap the bobbin holder and the traverse unit when viewed in the longitudinal direction, and when viewed in
  • the contact roller is configured to apply the contact pressure to the packages formed by winding the traversed yarns onto the bobbins and is provided in the vicinity of the bobbin holder and the traverse unit.
  • the supporting portions supporting the end portions in the longitudinal direction of the contact roller are therefore provided in the vicinity of the bobbin holder and the traverse unit, too.
  • the supporting portions are fixed, and the rigidity improving member is provided so as not to overlap the bobbin holder and the traverse unit when viewed in the longitudinal direction.
  • the rigidity improving member has a part which is longer than the supporting portions in the direction orthogonal to the direction in which the supporting portions extend.
  • the bending rigidity of the roller supporting member is improved in the longitudinal direction. It is therefore possible to improve the bending rigidity or the like of the roller supporting member while avoiding interference with the bobbin holder and the traverse unit. In this way, the rigidity of the roller supporting member is improved while restraining increase in size of the apparatus.
  • the yarn winder of the first aspect is arranged such that, when viewed in the longitudinal direction, at least a part of the rigidity improving member is provided so as not to overlap the supporting portions.
  • the overlapped part When viewed in the longitudinal direction, in case where the rigidity improving member is provided to overlap the supporting portions, the overlapped part is located between the contact roller and the traverse unit. It is therefore difficult to increase the cross-sectional area taken along the direction orthogonal to the longitudinal direction. According to the present invention, the cross-sectional area is increased at the part where the rigidity improving member does not overlap the supporting portions when viewed in the longitudinal direction, with the result that the rigidity of the roller supporting member is further improved.
  • the yarn winder of the first or second aspect is arranged such that each of the supporting portions is a rod-shaped or plate-shaped and is long in the radial direction.
  • a space is formed in the region surrounded by the contact roller, the supporting portions, and the rigidity improving member. Because the rigidity of the roller supporting member is improved by the rigidity improving member even when the supporting portions are rod-shaped or plate-shaped and extend in the radial direction, the other members or the like can be provided in the above-described space while the rigidity of the roller supporting member is improved, with the result that the apparatus is downsized.
  • the yarn winder of any one of the first to third aspects further includes: a frame which extends in the longitudinal direction and supports the roller supporting member, wherein, a cross section of at least a part in the longitudinal direction of the rigidity improving member, which is taken along a direction orthogonal to the longitudinal direction, at least partially surrounds a cross section of the frame taken along the direction orthogonal to the longitudinal direction.
  • a cross section in the direction orthogonal to the longitudinal direction of at least a part of the rigidity improving member is shaped to at least partially surround the frame. To put it differently, the rigidity improving member and the frame share a part of the space where the frame is provided. As a result, the cross-sectional area is enlarged while increase in size of the apparatus is restrained.
  • the yarn winder of the fourth aspect is arranged such that a cross section of at least a part in the longitudinal direction of the rigidity improving member, which is taken along the direction orthogonal to the longitudinal direction, entirely surrounds the cross section of the frame in the direction orthogonal to the longitudinal direction.
  • the rigidity of the rigidity improving member when the cross section of at least a part of the rigidity improving member in the direction orthogonal to the longitudinal direction is shaped to entirely surround the frame, the rigidity of the rigidity improving member is significantly improved.
  • the rigidity of the roller supporting member is therefore significantly improved while increase in size of the apparatus is restrained.
  • the yarn winder of the fifth aspect is arranged such that the rigidity improving member is cylindrical in shape and extends in the longitudinal direction.
  • the rigidity improving member is cylindrical in shape and extends in the longitudinal direction, and the rigidity improving member on the whole entirely surrounds the frame in cross section taken in the direction orthogonal to the longitudinal direction.
  • the rigidity of the roller supporting member is therefore further improved.
  • the yarn winder of any one of the fourth to sixth aspects is arranged such that the roller supporting member is supported by the frame to be swingable about a swing shaft extending in the longitudinal direction.
  • the roller supporting member is supported to be swingable. This indicates that the entirety of the roller supporting member and the entirety of the contact roller do not move. Because it is unnecessary to provide a space for allowing the roller supporting member, etc. to move and a guide member or the like for guiding the roller supporting member, it is possible to restrain increase in size of the apparatus.
  • the yarn winder of the seventh aspect is arranged such that the frame is polygonal in shape when viewed in the longitudinal direction, and the swing shaft is provided at a fixed portion which is fixed to one of outer circumferential surfaces of the frame, the one of the surfaces not being a surface closest to the contact roller when viewed in the longitudinal direction.
  • the rigidity improving member and the frame tends to interfere with each other if the swing angle of the roller supporting member is large.
  • the swing shaft is provided in the fixed portions which are fixed to a surface which is not the surface closest to the contact roller among the surfaces of the frame. Because the swing shaft is positioned so that the distance between the swing shaft and the rotation shaft of the contact roller is long, the swing range of the contact roller is arranged to be wide even though the swing angle of the roller supporting member is small. Furthermore, because the swing angle of the roller supporting member when the contact roller swings is small, interference between the rigidity improving member and the frame is avoidable.
  • the yarn winder of the seventh aspect is arranged such that the frame has a top surface, and the swing shaft is provided at the fixed portion fixed to the top surface.
  • the swing shaft is provided at the fixed portions fixed to the top surface of the frame. Because the downward force acting on the frame due to the weight of the roller supporting member is stably received by the top surface, a stable structure is realized.
  • the yarn winder of any one of the seventh to ninth aspects is arranged such that the frame is rectangular in shape when viewed in the longitudinal direction.
  • the frame is a quadrangular prism in shape, processing is easily done in the manufacture.
  • FIG. 1 is a profile of a take-up apparatus 1 including a yarn winder 4 (detailed later) of the present embodiment.

  • the base 20 supports members such as the turret 23 and the frame 27.
  • the fulcrum guides 21 are provided for the yarns Y, respectively, and are lined up in the front-rear direction. As the yarns Y are threaded onto the respective fulcrum guides 21, the fulcrum guides 21 function as fulcrums of the traversal of the respective yarns Y.

  • the number of the bobbins B attached to one bobbin holder 24 is, for example, 16.
  • the two bobbin holders 24 are rotationally driven by their respective winding motors (not illustrated).
  • the contact roller 25 is a roller having an axis substantially in parallel to the front-rear direction and is provided at a position which is above the upper bobbin holder 24 and below the traverse unit 22.

  • the distance between the bobbin holder 24 to which the bobbins B onto which the yarns Y are wound and the contact roller 25 is increased. Because the contact roller 25 is swingably supported by the frame 27, the contact roller 25 swings in accordance with the movement of the bobbin holder 24 and the packages P (see the dotted arrow in FIG. 2 ). With this, the contact between the contact roller 25 and the packages P is maintained.

  • the rigidity improving member 32 When viewed in the front-rear direction, the rigidity improving member 32 is provided to surround the frame 27. To put it differently, the frame 27 is provided inside the rigidity improving member 32 when viewed in the front-rear direction. The gap between the rigidity improving member 32 and the frame 27 is about 20mm long. The rigidity improving member 32 is provided at a position which is leftward and above the bobbin holder 24 and to the left of the traverse unit 22 (see FIG. 5 (a) ). In this way, the rigidity improving member 32 is provided so as not to overlap the bobbin holder 24 and the traverse unit 22 when viewed in the front-rear direction.

  • the rigidity improving member 32 is provided so as not to overlap the bobbin holder 24 and the traverse unit 22 when viewed in the front-rear direction. On this account, the bending rigidity or the like of the roller supporting member 26 is improved by the rigidity improving member 32 while avoiding interference with the bobbin holder 24 and the traverse unit 22. Furthermore, because the rigidity improving member 32 is shaped to entirely surround the frame 27 in cross section as described above, the rigidity improving member 32 and the frame 27 share a part of the space where the frame 27 is provided, and the rigidity improving member 32 has high rigidity.
  • the fixed portions 44 in which the swing shaft 45 is provided are fixed to the top surface 43. With this arrangement, the downward force acting on the frame 27 due to the weight of the roller supporting member 26 is stably received by the top surface 43. Furthermore, the swing range of the contact roller 25 is widened and interference between the roller supporting member 26 and the frame 27 is suppressed, as described below. If, as shown in FIG. 6(a) , the fixed portions 44 are fixed to a right side surface of the frame 27 which is the closest to the contact roller 25 among the outer circumferential surfaces of the frame 27, the distance between the swing shaft 45 and the rotational shaft 46 of the contact roller 25 is short when viewed in the front-rear direction.
  • the swing angle of the roller supporting member 26 when the contact roller 25 swings is large, with the result that the frame 27 and the rigidity improving member 32 surrounding the frame 27 tend to interfere with each other (see two-dot chain lines in FIG. 6(a) ).
  • the fixed portions 44 are fixed to a surface other than the right side surface, i.e., fixed to the top surface 43 as shown in FIG. 6(b) , the above-described distance is relatively long.
  • the swing range of the contact roller 25 relative to the swing angle of the roller supporting member 26 is therefore wide (see two-dot chain lines in FIG. 6(b) ).
  • the swing angle of the roller supporting member 26 when the contact roller 25 swings is small, interference between the rigidity improving member 32 and the frame 27 is less likely to occur.
  • the rigidity improving member 32 is fixed to the radially outer parts of the arm members 31 and is provided so as not to overlap the bobbin holder 24 and the traverse unit 22 when viewed in the front-rear direction. Furthermore, when viewed in the front-rear direction, the rigidity improving member 32 has a part which is longer than the arm member 31 in the direction orthogonal to the direction in which the arm member 31 extends. With this rigidity improving member 32, the bending rigidity of the roller supporting member 26 is improved in the front-rear direction. It is therefore possible to improve the bending rigidity or the like of the roller supporting member 26 while avoiding interference with the bobbin holder 24 and the traverse unit 22. In this way, the rigidity of the roller supporting member 26 is improved while restraining increase in size of the yarn winder 4.
  • the rigidity improving member 32 When viewed in the front-rear direction, at least a part of the rigidity improving member 32 is provided so as not to overlap the arm members 31F and 31R.
  • the cross-sectional area of the rigidity improving member 32 in the direction orthogonal to the front-rear direction is increase at this part, and hence the rigidity of the roller supporting member 26 is further improved.
  • a space is formed in the region surrounded by the contact roller 25, the arm members 31F and 31R, and the rigidity improving member 32. Because the rigidity of the roller supporting member 26 is improved by the rigidity improving member 32 even when the arm members 31F and 31R are plate-shaped and extend in the radial direction as described above, members such as the traverse unit 22 can be provided in the above-described space while the rigidity of the roller supporting member 26 is improved, with the result that the yarn winder 4 is downsized.
  • the rigidity improving member 32 is cylindrical in shape and extends in the front-rear direction, and the rigidity improving member 32 on the whole entirely surrounds the frame in cross section taken in the direction orthogonal to the front-rear direction. In this way, the rigidity improving member 32 and the frame 27 share a part of the space where the frame 27 is provided, and rigidity improving member 32 has high rigidity. The rigidity of the roller supporting member 26 is therefore significantly improved while increase in size of the apparatus is restrained.
  • the roller supporting member 26 is supported to be swingable. This indicates that the entirety of the roller supporting member 26 and the entirety of the contact roller 25 do not move. Because it is unnecessary to provide a space for allowing the roller supporting member 26, etc. to move and a guide member or the like for guiding the roller supporting member 26, it is possible to restrain increase in size of the apparatus.
  • the swing shaft 45 is provided in the fixed portions 44 which are fixed to a surface (the top surface 43 in the present embodiment) which is not the surface closest to the contact roller 25 among the surfaces of the frame 27. Because the swing shaft 45 is positioned so that the distance between the swing shaft 45 and the rotation shaft 46 of the contact roller 25 is long, the swing range of the contact roller 25 is arranged to be wide even though the swing angle of the roller supporting member 26 is small. Furthermore, because the swing angle of the roller supporting member 26 when the contact roller 25 swings is small, interference between the rigidity improving member 32 and the frame 27 is avoidable.
  • the swing shaft 45 is provided at the fixed portions 44 fixed to the top surface 43 of the frame 27. Because the downward force acting on the frame 27 due to the weight of the roller supporting member 26 is stably received by the top surface 43, a stable structure is realized.
  • the frame 27 is a quadrangular prism in shape, processing is easily done in the manufacture.
