Definitions

  • the present invention relates to yarn feeding mechanisms of flat knitting machines, and specifically relates to how to prevent slack of yarn in a feeding path that supplies a plurality of yarns to a yarn carrier.
  • a technique has been known in which a top tension device or a side tension device is provided in a feeding path through which a yarn fed out from a cone is supplied to a yarn carrier so as to apply tension to the yarn in order to prevent slack of yarn in the feeding path (for example, see Patent Literature 1).
  • a technique also has been known in which a plurality of yarns are combined into a folded yarn by a yarn combining device, and the folded yarn is supplied to the yarn carrier via the feeding path.
  • Patent Literature 1 Japanese Unexamined Patent Application Publication No. 2010-144301
  • the used amounts of yarns are each different depending on the difference in resistance applied to each of the yarns or the difference between the inner periphery and the outer periphery of the stitch formed during knitting.
  • Prior art document CN 202 144 544 U discloses a circular knitting machine for which a plurality of yarns is fed from a plurality of yarn feeders, each comprising guide grooves with a symmetric V-shape.
  • the yarn feeding mechanism is designed so as to reduce interference situations between the respective yarns and to avoid the yarns entwining.
  • Prior art document JP H04 11057 A discloses an interlacing yarn, which is formed by an interlacing yarn forming machine and is fed directly to a knitting machine.
  • the present invention assumes a yarn feeding mechanism for a flat knitting machine which is configured to form a plurality of yarns into a folded yarn by a yarn combining device and supplied to a yarn carrier. Further, a V-groove guide roller having a substantially V-shaped groove is rotatably supported in the feeding path from the yarn combining device to the yarn carrier. Moreover, it is characterized in that a rotation shaft of the V-groove guide roller is inclined relative to a direction perpendicular to the feeding path so that the folded yarn can be easily rolled from one inclined surface of two inclined surfaces of the groove to a valley.
  • a line tracing a valley of the groove of the V-groove guide roller in a circumferential direction may form one cycle of a sine curve for one turn of the V-groove guide roller in an expanded state.
  • an active yarn feeder may be disposed in the feeding path so as to actively feed the folded yarn to the V-groove guide roller depending on the demand.
  • an inclined angle changing mechanism may be disposed to change the inclined angle of the rotation shaft of the V-groove guide roller relative to the direction perpendicular to the feeding path.
  • a downstream-side V-groove guide roller having a substantially V-shaped groove is rotatably supported in the feeding path at a position closer to the yarn carrier than to the V-groove guide roller.
  • the rotation shaft of the downstream-side V-groove guide roller may be inclined in the direction opposite to the inclined direction of the V-groove guide roller with respect to the direction perpendicular to the feeding path so that the folded yarn rolled by the V-groove guide roller is rolled in the opposite direction.
  • a downstream-side recessed groove guide roller having a recess-shaped flat groove that is in contact with the folded yarn at the bottom is rotatably supported in the feeding path at a position closer to the yarn carrier than to the V-groove guide roller.
  • a rotation shaft of the downstream-side recessed groove guide roller may be perpendicular to the feeding path such that the folded yarn rolled by the V-groove guide roller is fed out without being twisted while being in contact with the flat groove.
  • the rotation shafts of the V-groove guide rollers are inclined in the direction perpendicular to the feeding path so that the folded yarn from the yarn combining device is easily rolled from one inclined surface of the groove of the V-groove guide roller to the valley, the folded yarn is twisted in the feeding path and thus firmly twisted. Accordingly, it is possible to ensure prevention of slack of yarn in the feeding path without excessively increasing the tension of the folded yarn.
  • the valley of the groove meanderingly moves between the inclined surfaces during one turn of the V-groove guide roller, causing the inclined angles of the respective inclined surfaces to vary.
  • the folded yarn rolls only on one inclined surface, the folded yarn is rolled on the one inclined surface and is twisted when the valley moves to the other inclined surface with rotation of the V-groove guide rollers and the inclined angle of the one inclined surface becomes gently inclined.
  • the valley moves to one inclined surface and the inclined angle of one inclined surface become steeply inclined, the folded yarn moves to one inclined surface.
  • the active yarn feeder is provided so as to actively feed the folded yarn to the V-groove guide roller depending on the demand, the folded yarn actively fed can also be rolled from the inclined surface of the groove of the V-groove guide roller to the valley and can be smoothly twisted in the feeding path.
  • the inclined angle changing mechanism changes the inclined angle of the rotation shaft of the V-groove guide roller relative to the direction perpendicular to the feeding path, which of the inclined surfaces of the groove of the V-groove guide roller is to be used or the degree of twisting of the folded yarn can be changed depending on the types of the yarns. Accordingly, the degree of twisting of the folded yarn can be increased or decreased depending on the thickness, the types or the knitting conditions of the yarns.
  • the rotation shaft of the downstream-side V-groove guide roller located at a position close to the yarn carrier than to the V-groove guide roller in the feeding path is inclined in the direction opposite to the inclined direction of the V-groove guide roller with respect to the direction perpendicular to the feeding path so that the folded yarn which is rolled and twisted by the V-groove guide roller is rolled in the opposite direction from one inclined surface to the valley of the groove of the downstream-side V-groove guide roller, the folded yarn can be further twisted between both guide rollers and thus firmly twisted, thereby ensuring prevention of slack of the yarns in the feeding path.
  • the rotation shaft of the downstream-side V-groove guide roller is inclined in the direction opposite to the inclined direction of the V-groove guide roller with respect to the direction perpendicular to the feeding path, the folded yarn from the downstream-side V-groove guide roller to the knitting needle can also be twisted, and accordingly, knitting can be performed by the knitting needle while the folded yarn is in a twisted state.
  • the rotation shaft of the downstream-side recessed groove guide roller located at a position close to the yarn carrier than to the V-groove guide roller in the feeding path is perpendicular to the feeding path so that the folded yarn twisted by the V-groove guide roller is fed out without being twisted while being in contact with the flat groove of the downstream-side recessed groove guide roller. Accordingly, the folded yarn can be further twisted between both guide rollers and thus firmly twisted, thereby ensuring prevention of slack of the yarns in the feeding path.
  • twist of the folded yarn after it is in contact with the flat groove naturally returns. Accordingly, twist of the folded yarn between the rollers can be released at a position from the downstream-side recessed groove guide roller to the knitting needle so that knitting by the knitting needle can be performed in the state in which twist of the folded yarn is released.

  • Fig. 7 is an explanatory view which explains a twisting direction of the folded yarn 12 by the upstream-side and downstream-side V-groove guide rollers 24, 25 in the feeding path 20.
  • inclination of the shaft 242 of the upstream-side V-groove guide roller 24 facilitates rolling of the folded yarn 12 from one inclined surface 243A of the groove 241 to the valley.
  • the folded yarn 12 which is twisted in clockwise direction (the arrow direction indicated by the one-dotted chain line in Fig. 7 ) in the feeding path 20 to the yarn carrier 3 can be firmly twisted, thereby ensuring prevention of slack of the yarns 12A, 12B in the feeding path 20 without excessively increasing the tension of the folded yarn 12.
  • the shaft 252 of the downstream-side V-groove guide roller 25 is inclined in the direction opposite to the inclined direction of the upstream-side V-groove guide roller 24 with respect to the direction perpendicular to the feeding path 20 so that the folded yarn 12 twisted by the upstream-side V-groove guide roller 24 is rolled in the opposite direction.
