Definitions

  • the present invention relates to a fiber bundle concentrating device for a spinning machine.
  • Japanese Laid-Open Patent Publication No. 2002-69762 discloses a fiber bundle concentrating device that concentrates a drafted fiber bundle (sliver) before the bundle is twisted.
  • the fiber bundle concentrating device disclosed in the above publication includes a hollow forming member (suction pipe) and a perforated conveyer belt.
  • the hollow forming member is located downstream in the moving direction of fiber bundle of a pair of outlet rollers (a pair of final rollers) of a draft machine, and the conveyer belt is wound about a slide surface formed on the outer circumferential surface of the hollow forming member.
  • An inlet slit is formed in the slide surface of the hollow forming member. The inlet slit is covered with the conveyer belt.
  • the hollow forming member has a tightening roller, which is provided in the vicinity of the downstream end in the moving direction of the fiber bundle.
  • the tightening roller moves the conveyer belt while pressing the fiber bundle and the conveyer belt against the outer circumferential surface of the hollow forming member.
  • the inlet slit is inclined relative to the moving direction of the fiber bundle, and one of the two side edges on both sides in the widthwise direction of the slit forms a fiber guide edge.
  • the cover includes a support portion and a covering wall extending from the upper end of the support portion.
  • the support portion and the covering wall are formed integrally.
  • the support portion is coupled to a part of the slide surface that is located outside of the fiber guide edge.
  • An air inlet clearance is formed on the opposite side of the slit to the support portion of the inlet slit. The air inlet clearance is located between the covering wall and the conveyer belt.
  • the cover functions to further improve the compression (concentration) of the sliver.
  • the cover support portion is located in an area outside of the fiber guide edge, there is only a small amount of air flow from the outside area to the fiber guide edge. This results in insufficient air flow for moving the fiber bundle from the outside area toward the fiber guide edge. Accordingly, the concentration of the fiber bundle is insufficient. This lowers the quality of the yarn.
  • a fiber bundle concentrating device for a spinning machine is provided.
  • the fiber bundle concentrating apparatus is located downstream of a pair of final delivery rollers of a spinning machine.
  • the fiber bundle concentrating apparatus includes a suction pipe and an air-permeable conveyer belt.
  • the suction pipe has a suction slit.
  • the air-permeable conveyer belt is moved while being wrapped about a guide surface of the suction pipe so as to cover the suction slit.
  • the guide surface has first and second side edges that extend along both sides in the widthwise direction of the suction slit.
  • the first and second side edges define the width of the suction slit.
  • the first side edge functions as a guide edge for concentrating a fiber bundle.
  • the fiber bundle concentrating apparatus includes a cover.
  • the cover covers the suction slit from above, while covering an area outside of the second side edge. An air flow introducing clearance is provided between the guide edge and the cover.
  • a fiber bundle concentrating device 11 according to a first embodiment of the present invention will now be described with reference to Figs. 1A to 3B .
  • the fiber bundle concentrating device 11 is located in a draft machine 12 at a position downstream of a pair of final delivery rollers 13.
  • the fiber bundle concentrating device 11 includes a delivery portion 14, a suction pipe 15, an air-permeable conveyer belt 16, and a guide portion 17.
  • the pair of final delivery rollers 13 includes a front bottom roller 131 and a front top roller 132.
  • the delivery portion 14 includes a rotary shaft 18 parallel with the front bottom roller 131, a bottom nip roller 181 formed on the rotary shaft 18, and a top nip roller 19 pressed against the bottom nip roller 181 via the air-permeable conveyer belt 16.
  • the top nip roller 19 is supported by a weighting arm (not shown) with a support member 20 at every other spindle.
  • the support member 20 is formed integrally with a support member (not shown) of the front top roller 132.
  • the suction pipe 15 is located on the upstream side in the moving direction of a fiber bundle F relative to the nip point (the contact point of the top nip roller 19 and the air-permeable conveyer belt 16) of the delivery portion 14.
  • a plurality of roller stands 21 are arranged at predetermined intervals along the longitudinal direction of the spinning frame [the direction perpendicular to the plane of Fig. 1A ].
  • a support arm (not shown) is arranged at an intermediate position between each adjacent pair of the roller stands 21.
  • the support arms are supported by a support beam (not shown), which extends along the longitudinal direction of the spinning frame.

  • the intermediate gear 25 is meshed with the gear portion 133 and the gear 22. Rotational force of the front bottom roller 131 is transmitted to the rotary shaft 18 via the gear portion 133, the intermediate gear 25, and the gear 22.
  • a suction duct (not shown) is arranged in the spinning frame to extend along the longitudinal direction of the spinning frame.
  • the suction pipe 15 extends parallel with the suction duct and is connected to the suction duct by a connecting pipe 26.
  • the suction pipe 15 has a guide surface 28, in which a suction slit 27 is formed.
  • the guide surface 28 is a curved surface bulging outward from the suction pipe 15.
  • the air-permeable conveyer belt 16 wraps and contacts the suction pipe 15, the guide portion 17, and the bottom nip roller 181.
  • the suction slit 27 is covered with the air-permeable conveyer belt 16.
  • the air-permeable conveyer belt 16 is formed of woven cloth so as to have an adequate air permeability.
  • the bottom nip roller 181 and the top nip roller 19 rotate in opposite directions, so that the air-permeable conveyer belt 16 between the bottom nip roller 181 and the top nip roller 19 is moved in a direction of arrow R. Accordingly, the fiber bundle F between the top nip roller 19 and the air-permeable conveyer belt 16 is moved from an upstream end 271 to a downstream end 272 of the suction slit 27.
  • the suction slit 27 is inclined relative to the conveying direction of the air-permeable conveyer belt 16 along the guide surface 28.
  • the guide surface 28 has a pair of side edges 29, 30 extending along both sides in the direction of the width of the suction slit 27 (the direction of arrow H in Fig. 2A , or the longitudinal direction of the suction pipe 15).
  • the side edges 29, 30 define the width of the slit 27.
  • the side edge (first side edge) 29 functions as a guide edge (hereinafter, referred to as a guide edge 29) that concentrates the fiber bundle F.
  • the width of the suction slit 27 decreases partway from the upstream end toward the downstream end along the conveying direction R of the air-permeable conveyer belt 16.
  • a cover 33 is provided on the guide surface 28.
  • the cover 33 covers the suction slit 27 from above, and an area outside of the side edge 30 (a second side edge or non-guide edge), which is opposite to the guide edge 29.
  • the cover 33 includes a side wall 31 in an area of the guide surface 28 outside of the side edge 30 [an area left of the side edge 30] and a covering wall 32 located above the suction slit 27.
  • the side wall 31 and the covering wall 32 are formed integrally.
  • the area outside of the side edge 30 refers to an area on the opposite side of the suction slit 27 to the side edge 30, and will hereinafter be referred to as a first area.
  • the side wall 31 extends toward the guide surface 28, and the covering wall 32 extends from the upper end of the side wall 31 in a direction perpendicular to the side wall 31.
  • the lower end (distal end) of the side wall 31 contacts the guide surface 28 such that there is no clearance between the side wall 31 and the guide surface 28, and the covering wall 32 is coupled to the side wall 31 such that there is no clearance between the covering wall 32 and the side wall 31.
  • a projecting portion 331 is formed integrally with the inner surface of the side wall 31 (the surface facing the suction slit 27) and the inner surface of the covering wall 32.
  • the projecting portion 331 projects toward the air-permeable conveyer belt 16 and reaches a point before the side edge 30, and a small clearance exists between the projecting portion 331 and the air-permeable conveyer belt 16.
  • the space between an inner surface 320 of the covering wall 32 (parts except for the projecting portion 331) and the guide surface 28 is constant.
  • the space between the projecting portion 331 and the guide surface 28 is also constant.
  • a distal edge 321 of the covering wall 32 is slightly inclined relative to the conveying direction R of the air-permeable conveyer belt 16 on the guide surface 28.
  • the length of the covering wall 32 along the widthwise direction H of the suction slit 27 increases along the direction opposite to the conveying direction R of the air-permeable conveyer belt 16. That is, the length of the covering wall 32 along the widthwise direction H of the suction slit 27 is greater in a part close to the upstream end 271 of the suction slit 27 than in a part close to the downstream end 272 of the suction slit 27.
  • the distal edge 321 of the covering wall 32 is located in an area (second area) outside of the guide edge 29 [an area right of the guide edge 29 in Fig. 2A ], and the covering wall 32 covers the guide surface 28 to a position beyond the guide edge 29 along the widthwise direction H of the suction slit 27.
  • the covering wall 32 is separated upward from the suction slit 27 and covers most of the suction slit 27.
  • the upstream end 271 and the downstream end 272 of the suction slit 27 are out of the area covered with the covering wall 32.
  • the side wall 31 and the covering wall 32 form the cover 33, which spreads from a part of the guide surface 28 in the first area [the area left of the side edge 30 in Fig. 2A ] to a space above a part of the guide surface 28 in the second area [the area right of the guide edge 29 in Fig. 2A ].
  • the second area is an area on the opposite side of the guide edge 29 to the suction slit 27.
  • the first area and the second area are on the opposite sides of the suction slit 27.
  • the cover 33 is supported to the support member 20 with a bracket (not shown). By arranging the weighting arm (not shown) at a released position, the cover 33, together with the top nip roller 19, can be separated from the suction pipe 15.
  • An air flow introducing clearance S is formed between the guide edge 29 (in the present embodiment, the surface of the air-permeable conveyer belt 16 arranged on the guide edge 29) and the distal edge 321 of the covering wall 32.
  • the space between the cover 33 and the guide surface 28 is open to the second area via the air flow introducing clearance S.
  • the fiber bundle F is moved while being traversed by the operation of a traverse device (not shown).
  • the speed of the traverse motion is set to a smaller value than the speed of the moving speed of the fiber bundle F.
  • the upstream end 271 of the suction slit 27 is perpendicular to the conveying direction R of the air-permeable conveyer belt 16. Even if the position of the fiber bundle F is changed due to the traverse motion, the distance between the nip point of the pair of final delivery rollers 13 and the suction slit 27 is maintained to a constant value.
  • the fiber bundle F is drafted by the draft machine 12, and is then guided to the fiber bundle concentrating device 11 from the pair of final delivery rollers 13.
  • the bottom nip roller 181 and the top nip roller 19 are rotated such that the speed of their outer circumferential surfaces is substantially equal to the speed of the outer circumferential surfaces of the pair of final delivery rollers 13.
  • the fiber bundle F is moved downstream while being twisted.
  • Suction of the suction duct acts on the suction pipe 15 through the connecting pipe 26, and air passes through the air-permeable conveyer belt 16 and is drawn into the suction pipe 15 from the suction slit 27.
  • Suction created at the suction slit 27 acts on the fiber bundle F through the air-permeable conveyer belt 16.
  • the fiber bundle F is moved along the air-permeable conveyer belt 16 while being concentrated along the suction slit 27 in the space between the cover 33 and the guide surface 28. In this case, air in the vicinity of the suction slit 27 and in the vicinity of the surface of the air-permeable conveyer belt 16 continuously flows into the suction slit 27.
  • the side wall 31 of the cover 33 blocks air flow from the first area to the suction slit 27, and the covering wall 32 blocks air flow from the area above the suction slit 27 to the suction slit 27. Accordingly, air flow toward the suction slit 27 along the widthwise direction H of the suction slit 27 becomes an air flow that mainly flows to the suction slit 27 from the air flow introducing clearance S between the distal edge 321 of the covering wall 32 and the surface of the air-permeable conveyer belt 16. As a result, the fiber bundle F is attracted to a position on the air-permeable conveyer belt 16 that corresponds to the suction slit 27.
  • the fiber bundle F is then concentrated by the conveying effect of the air-permeable conveyer belt 16 and the air flow mainly into the suction slit 27 from the air flow introducing clearance S between the distal edge 321 of the covering wall 32 and the surface of the air-permeable conveyer belt 16.

  • the hairiness was particularly improved.
  • the cover 33 was used, the differences in hairiness among positions X, Y and Z were small compared to the case where the cover 33 was not used. That is, the hairiness was stable regardless of the traverse position.
