Definitions

  • the present invention relates to a spinning winder which is arranged to wind yarns spun out from a spinning unit onto respective bobbins attached to a bobbin holder.
  • a spinning winder recited in Patent Literature 1 (International Publication No. 2011/009498 ( Fig. 1 )) is arranged such that a plurality of bobbins are attached in series to a bobbin holder along the axial direction and a plurality of heating rollers are provided above the axial center of the bobbin holder to heat and draw the yarns.
  • the axis of each heating roller is orthogonal to the axis of the bobbin holder. Yarns spun out from a spinning unit are serially wound onto the heating rollers below, and then wound onto corresponding bobbins.
  • the number of heating rollers provided is more than one in order to sufficiently heat yarns to a desired temperature.
  • yarns are sucked through a suction port of a sucking unit (air sucker), the suction port of the hose of the sucking unit is inserted from the end face side into a gap between neighboring heating rollers, and the suction port is moved in gaps among the heating rollers.
  • the sucking unit is large and heavy.
  • the hose of the sucking unit is large in diameter in order to suck yarns without clogging, and is inflexible.
  • the spinning winders are aligned in directions orthogonal to the axis of the bobbin holder, i.e., in directions in parallel to the axes of the heating rollers. For example, an operation to remove a package formed by winding a yarn onto a bobbin from the bobbin holder is performed such that an operator on the outside of the leading end of the bobbin holder performs the operation from the leading end side of the bobbin holder.
  • EP 0 010 772 A1 relates to a method for threading a yarn delivered from a godet roller on a bobbin and an apparatus for effecting the same.
  • polyester yarns spun from spinnerets are delivered to bobbins held on a bobbin holder in winding apparatuses through godet rollers which have mirror finished surfaces and axially grooved surfaces.
  • the yarns are moved to the axially grooved surface from the mirror finished surfaces by means of a yarn displacing guide disposed upstream of the uppermost godet roller.
  • JP H06-212509 A discloses a spinning system capable of readily changing the relative distance of equipment such as a spinning machine or spinning winder.
  • An object of the present invention is therefore to provide a spinning winder with improved operating efficiency in yarn threading onto a plurality of heating rollers from the leading end side of the winding axis.
  • a spinning winder of the present invention includes the features of claim 1.
  • the bobbins attached to the winding axis are removed from the leading end side of the winding axis, and hence the working space for operations is provided in front of the winding axis.
  • the heating rollers are provided on the leading end side of the winding axis and the end faces of the heating rollers face the working space.
  • the spinning winder and another spinning winder are aligned in directions orthogonal to the winding axis.
  • the heating rollers are provided above the leading end of the winding axis.
  • the winding axis does not obstruct the yarn threading onto the heating rollers from the leading end side of the winding axis, and therefore the efficiency in the yarn threading is further improved.
  • the heating rollers may be provided between the winder main body and an adjacent winder main body.
  • the winding axis does not obstruct the yarn threading onto the heating rollers from the leading end side of the winding axis, and therefore the efficiency in the yarn threading is further improved.
  • the axial direction of the heating rollers is in parallel to the axial direction of the winding axis. Assuming that no guide roller is provided, the length of the winding axis increases as the number of bobbins increases, yarns remote from the heating rollers are distributed in a spread manner, and hence the bending angles of yarns wound onto the bobbins increase toward the edges of the winding axis. According to the arrangement above, the yarns wound onto the heating rollers are supplied to the guide roller arranged to be orthogonal to the winding axis, and therefore the yarns are aligned in the directions orthogonal to the alignment directions of the bobbins. Since the yarns leaving the guide roller are distributed in the tangential directions of the roller, the yarns immediately after leaving the guide roller runs toward the traversing fulcrum guides without being bended.
  • the efficiency in the yarn threading is not significantly deteriorated even if the number of heating rollers is increased, when the heating rollers are provided on a single vertical surface on the leading end side of the winding axis and the end faces of the rollers face the same direction as the leading end of the bobbin holder.
  • a plurality of heating rollers are provided on the leading end side of a winding axis, and the end faces of the heating rollers face a working space.
  • Fig. 1 is a profile of a spinning winder according to the present embodiment.
  • the spinning winder 1 is arranged so that yarns 10 which are serially spun out from a spinning machine 2 at an upper part are fed to a winding unit 3 at a lower part via a godet roller group 20 and two guide rollers 11 and 12, and the yarns 10 are wound by the winding unit 3.
  • Fig. 2 is a plan view illustrating the arrangement of the spinning winders.
  • the spinning winders 1 taking into account of, for example, the arrangement of spinnerets spinning out the yarns 10 of the spinning machine 2 upstream of (i.e., above) the spinning winder 1 in the yarn running direction and the removal of bobbins B from a cantilevered bobbin holder 7 (described later) from its leading end side, the spinning winders 1 are aligned in directions orthogonal to axes 7a of later-described bobbin holders 7 so that the spinning winders 1 are efficiently arranged within a limited space, and a working space 30 where an operator performs operations is provided on the leading end side or in front of the bobbin holders.
  • a working space 30 where an operator performs operations is provided on the leading end side or in front of the bobbin holders.
  • the winding unit 3 As shown in Fig. 1 , the winding unit 3 is provided below the spinning machine 2.
  • the winding unit 3 forms packages P by winding, onto bobbins B, yarns 10 supplied from the spinning machine 2 via the godet roller group 20 and the two guide rollers 11 and 12.
  • This winding unit 3 includes components such as a main body frame 5, a disc-shaped turret 6 rotatable with respect to the main body frame 5, two bobbin holders 7 (winding axes) each cantilevered at its rear end by the turret 6 and to each of which a plurality of bobbins B are attached in series to the axis 7a, and a contact roller 9 which is vertically movable with respect to the main body frame 5 and approaches and moves away from the bobbins B attached to the bobbin holder 7.
  • the winding unit 3 winds the yarns 10 onto the rotating bobbins B, as the bobbin holder 7 is rotated by an unillustrated motor and therefore the bobbins B attached to this bobbin holder 7 are rotated. At the same time, the yarns 10 wound onto the bobbins B are traversed in the axial directions of the bobbins B about later-described fulcrum guides 13, by a traverse guide 8 provided above each bobbin B.
  • the yarns 10 traversed about the fulcrum guides 13 by the traverse guide 8 are wound onto the bobbins B, with the result that packages P are formed.
  • the contact roller 9 contacts the outer circumference of a package P when a yarn is wound onto a bobbin B and rotates while applying a predetermined contact pressure to the package P, so as to shape the package P.
  • the packages P attached to the bobbin holder 7 are pushed from the base end side to the leading end side of the bobbin holder 7 by an unillustrated pusher, and eventually removed from the bobbin holder 7 from the leading end side.
  • Fig. 3 is a perspective view of the godet roller group and the guide rollers.
  • Fig. 4 is a front elevation of the godet roller group and the guide rollers.
  • a thermal insulation box 26 is depicted by two-dot chain lines in order to clearly show the inside of the thermal insulation box 26.
  • the spinning winder 1 includes components such as a frame 14 provided to be further from the viewer of Fig. 1 than the winding unit 3, a godet roller group 20 which receives the yarns 10 spun out from the spinning machine 2, two guide rollers 11 and 12 which receive the yarns 10 from the godet roller group 20, and fulcrum guides 13 (distribution guides) that distribute the yarns 10 wound on the downstream-side guide roller 12 to the bobbins B attached to the bobbin holder 7 of the winding unit 3 and each functions as a fulcrum of traversal by the traverse guide 8.
  • a frame 14 provided to be further from the viewer of Fig. 1 than the winding unit 3
  • a godet roller group 20 which receives the yarns 10 spun out from the spinning machine 2
  • two guide rollers 11 and 12 which receive the yarns 10 from the godet roller group 20
  • fulcrum guides 13 distributed guides
  • the godet roller group 20 is constituted by, for example, four godet rollers 21 to 24 which are provided below the spinning machine 2 and on the working space 30 side (leading end side) of the bobbin holder 7.
  • the godet rollers 21 to 24 are arranged from the upstream to the downstream of the yarn running direction in this order.
  • These godet rollers 21 to 24 are housed in the thermal insulation box 26 which is made of a heat insulating material and is substantially rectangular parallelepiped.
  • the godet rollers 21 to 24 are staggered and the axes 21a to 24a thereof are arranged to be in parallel to the axis 7a of the bobbin holder 7.
  • the thermal insulation box 26 has an openable door 26a opposing the end faces 21b to 24b of the godet rollers 21 to 24. When this door 26a is open, the end faces 21b to 24b of the godet rollers 21 to 24 are exposed to the working space 30 from the thermal insulation box 26. This allows an operator in the working space 30 to easily perform operations inside the thermal insulation box 26, such as yarn threading on the godet rollers 21 to 24.
  • the thermal insulation box 26 has two slits 28 and 29. Through the slit 28, the yarns 10 supplied to the most upstream godet roller 21 from the spinning machine 2 pass. Through the slit 29, the yarns 10 supplied from the most downstream godet roller 24 to the winding unit 3 pass.
  • the godet rollers 21 to 24 are provided on the side opposite to the door 26a of the thermal insulation box 26 and are drive rollers cantilevered by an unillustrated frame.
  • the yarns 10 supplied from the spinning machine 2 pass through the slit 28 of the thermal insulation box 26, enter the thermal insulation box 26, and are fed to the most upstream godet roller 21.
  • the yarns 10 fed to the godet roller 21 are wound onto the godet rollers 21 to 24 from the upstream, with winding angles of less than 360 degrees.
  • the godet rollers 21 to 24 are rotated by an unillustrated motor, the yarns are fed downstream, pass through the slit 29 of the thermal insulation box 26, and go out from the thermal insulation box 26.
  • the godet rollers 21 to 24 are rotated such that a roller on the downstream rotates at a higher speed, and therefore the yarns 10 are drawn by differences in the rotation speeds of the rollers.
  • each of the godet rollers 21 to 24 is a heating roller provided with a heater 27 therein, and hence the yarns 10 wound on the godet rollers 21 to 24 are heated. Since the godet rollers 21 to 24 are provided in the thermal insulation box 26 and the door 26a is closed, the heat generated by the heaters 27 does not leak out from the thermal insulation box 26.
  • the two guide rollers 11 and 12 will be described. As shown in Fig. 1 , Fig. 3 , and Fig. 4 , the two guide rollers 11 and 12 are provided above the main body frame 5 of the winding unit 3 and have axes 11a and 12a extending in directions orthogonal to the axis 7a of the bobbin holder 7 (i.e., orthogonal to the axes 21a to 24a of the godet rollers 21 to 24). Furthermore, the guide rollers 11 and 12 are rotatably supported by the frame 14 and are drive rollers driven by an unillustrated motor.
  • the guide roller 11 is provided immediately below the godet roller group 20 whereas the guide roller 12 is provided above the substantial center of the fulcrum guides 13 in the alignment directions. Since the guide roller 12 is moved to the yarn threading position 12a (indicated by a dotted line in Fig. 1 ) near the guide roller 11 at the time of yarn threading, the yarn threading can be easily done.
  • the fulcrum guides 13 are provided below the guide roller 12, above the traverse guides 8, and immediately above the traverse guides 8 and the bobbins B attached to the bobbin holder 7.
  • the fulcrum guides 13 are aligned along the axis 7a of the bobbin holder 7 with the same intervals as those of the bobbins B.
  • the yarns 10 supplied from the spinning machine 2 are sent out downward, and first of all wound on the most upstream godet roller 21 and then on the subsequent godet rollers, while being aligned in directions along the axes 21a to 24a.
  • the yarns 10 fed downstream in the yarn running direction from the most downstream godet roller 24 change the direction for 90 degrees and are then wound onto the guide roller 11 while being aligned in directions along the axis 11a of the guide roller 11. Thereafter, the yarns 10 wound onto the guide roller 11 are passed to the guide roller 12, and then threaded onto the respective fulcrum guides 13 and are fed to the winding unit 3 below.
  • Fig. 5 illustrates the yarn threading onto the godet roller group and is a perspective view of the godet roller group.
  • the yarns 10 sent out from the spinning machine 2 are sucked and captured by an operator by using the suction port 40a of the air sucker 40 taken from the working space 30.
  • the suction port 40a of the air sucker 40 sucking and capturing the yarns 10 is then inserted into the thermal insulation box 26 from the front side.
  • the air sucker 40 is moved anticlockwise along the circumference from the left of the most upstream godet roller 21.
  • the air sucker 40 passes through the gap between the godet rollers 21 and 23, then passes through the gap between the godet rollers 21 and 22, and eventually reach a position to the left of the godet roller 22.
  • the yarns 10 are wound onto the most upstream godet roller 21.
  • the godet rollers 21 to 24 are provided in the vicinity of the working space 30 and above the leading ends of the bobbin holders 7, to be overlapped with one another in the vertical directions.
  • the end faces 21b to 24b of the godet rollers 21 to 24 face the same direction as the leading ends of the bobbin holders 7.
  • the yarns 10 are sucked by the suction port 40a of the air sucker 40 and the suction port 40a of the air sucker 40 is inserted into the gaps among the godet rollers 21 to 24 from the front side when viewed from the working space 30, and the air sucker 40 is moved up and down and left and right along the circumferences of the godet rollers 21 to 24 without being bended.
  • the yarn threading is achieved only by these operations.
  • the bobbin holders 7 do not obstruct the operation, and hence the efficiency in the yarn threading from the working space 30 (i.e., from the leading end side of the bobbin holder 7) onto the godet rollers 21 to 24 is improved. Furthermore, trouble shooting such as removal of a yarn 10 wound onto the godet rollers 21 to 24 can be easily done.
  • the yarns 10 wound onto the godet rollers 21 to 24 are supplied to the guide rollers 11 and 12 having the axes 11a and 12a orthogonal to the axis 7a of the bobbin holder 7, to be aligned in directions orthogonal to the alignment directions of the bobbins B. Since the yarns 10 leaving the guide roller 12 are distributed in the tangential directions of the roller 12, the yarns 10 immediately after leaving the guide roller 12 runs toward the traversing fulcrum guides 13 without being bended.
  • the godet rollers 21 to 24 are provided on the leading end side of the bobbin holder 7 and the end faces 21b to 24b face the same direction as the leading ends of the bobbin holders 7, the efficiency in the yarn threading is not significantly deteriorated even if the number of godet rollers is increased.
  • the number of godet rollers (heating rollers) is large in order to obtain required properties of yarns.
  • the efficiency in yarn threading is not significantly deteriorated even if the number of godet rollers 50 is large, when the godet rollers 50 are provided in the vicinity of the working space (on the leading end side of the bobbin holder 7) and between the winding units 3 (more specifically, between the main body frames 5) and furthermore the end faces of the rollers 50 face the same direction as the leading ends of the bobbin holders 7.
  • the arrangement above is very effective in this case, too.
  • a winder main body by which a winding axis is cantilevered in the present embodiment is equivalent to the main body frame 5 provided with the turret 6 by which the bobbin holders 7 are cantilevered in the present embodiment.
  • the number and orientation of the guide rollers may be suitably changed on condition that the yarns 10 supplied from the godet roller group 20 are sent to the fulcrum guides 13 with small bending angles.
  • the most downstream guide roller may be provided to be in parallel to the axis 7a of the bobbin holder 7, on condition that this roller is disposed at a position much higher than the positions of the fulcrum guides 13.
  • the yarns 10 may be directly supplied from the godet roller group 20 to the fulcrum guides 13 without the intervention of the guide rollers 11 and 12.
  • fulcrum guides 13 function not only as guides about which the yarns are traversed but also as distribution guides for distributing the yarns 10 to the bobbins B, fulcrum guides for traversal and distribution guides may be independently provided.
  • the axes 21a to 24a of the godet rollers 21 to 24 are arranged to be in parallel to the axis 7a of the bobbin holder 7, the axes 21a to 24a and the axis 7a may be slightly non-parallel on condition that an operator in the working space 30 is able to face the end faces 21b to 24b of the godet rollers 21 to 24.
  • the spinning winder may be arranged so that the bobbin holders 7 are supported not only on the base end side but also on the leading end side by a supporting member, as recited in literatures such as Japanese Examined Patent Publication No. 5224/1995 (Tokukouhei 7-5224) and Japanese Patent No. 3440839 .
