Definitions

  • the present invention relates to a weft insertion method for an air jet loom and a flight promotor attaching device.
  • An air jet loom performs weft insertion by transporting weft yarns with high-pressure jet flow discharged from nozzles.
  • a weft yarn of an air jet loom is a yarn with a significantly small air friction resistance, such as a monofilament yarn and metal fiber
  • the weft yarn may not be able to fly over the fabric width in the reed passage, disrupting the weaving.
  • the weft yarn of an air jet loom is a multifilament yarn having a smaller air friction resistance than a spun yarn, which is formed by twisting fine short fibers, such as a flat yarn and a hard twist yarn, or a yarn having a high fiber stiffness, such as a hemp yarn
  • the weft yarn may not fly at a sufficient velocity. This may stop the operation of the loom or significantly increase the air consumption.
  • Japanese Laid-Open Patent Publications No. 51-92352 and No. 58-163758 disclose a weft insertion system and a weft insertion method.
  • the '352 publication discloses a weft insertion system that bonds a spherical solid object to a weft yarn.
  • the solid object is several tens of times the diameter of the weft yarn.
  • the weft yarn is inserted by directing a jet of fluid (air or water) to the weft yarn.
  • the '758 publication discloses a weft insertion method in a loom in which a jet of fluid carries a weft yarn in weft insertion.
  • the distal end region of a weft yarn is deformed by bending, for example, before weft insertion, so that the propelling force the weft yarn receives from the jet of fluid is increased.
  • the length of the deformed distal end region does not exceed the length of the weft selvage to be discarded.
  • the section to which the spherical solid object is bonded has a greater weight per length than the other section of the weft yarn to be inserted. This hinders the weft yarn from flying straight.
  • the yarn propelling force during flight of the weft yarn is increased compared to a straight weft yarn.
  • a weft insertion method in an air jet loom includes: attaching a flight promoter that has a greater surface area per unit weight than a weft yarn to a distal end portion of the weft yarn before weft insertion; and performing insertion of the weft yarn to which the flight promoter is attached.
  • a flight promotor attaching device in an air jet loom in which a flight promoter that has a greater surface area per unit weight than a weft yarn is attached to a distal end portion of the weft yarn before weft insertion.
  • an air jet loom includes a weft insertion system that includes two main nozzles 11 A and 11 B for weft insertion, tandem nozzles 12A and 12B, which are arranged on the upstream sides of the main nozzles 11 A and 11 B, respectively, and a plurality of sub-nozzles 13 for weft insertion that is arranged on the downstream side of the main nozzles 11 A and 11 B.
  • the tandem nozzles 12A and 12B are fixed by brackets or the like that are attached to a frame of the air jet loom or the floor surface.
  • the main nozzles 11A and 11 B and the sub-nozzles 13 are arranged on a sley 15 that is fixed to a pivot shaft 14 and pivots forward and backward in the front-rear direction of the air jet loom.
  • a profile reed 16 is fixed on the sley 15.
  • the profile reed 16 includes a plurality of dents 17 arranged in the weft insertion direction. As shown in Fig. 2 , guide recesses 17a of the dents 17 form a reed channel 18 that functions as the insertion path of weft yarns Y.
  • the sub-nozzles 13 are spaced apart from one another along the weft insertion path such that the ends of the sub-nozzles 13 face the reed channel 18. In Fig. 1 , the dents 17 are partially removed.
  • a main nozzle switching valve 19A is connected to the main nozzle 11 A
  • a main nozzle switching valve 19B is connected to the main nozzle 11 B
  • a tandem nozzle switching valve 20A is connected to the tandem nozzle 12A
  • a tandem nozzle switching valve 20B is connected to the tandem nozzle 12B by separate pipes 21.
  • a common pipe 22 connects the switching valves 19A, 19B, 20A and 20B to a main tank 23.
  • a controller (not shown) controls the switching valves 19A, 19B, 20A and 20B to control discharge timing of compressed air from each of the main nozzles 11 A and 11 B and the tandem nozzles 12A and 12B.

  • the weft insertion system includes a plurality of sets of three sub-nozzles 13.
  • the weft insertion system includes sub-nozzle switching valves 24, each of which is associated with one of the sets of the sub-nozzles 13.
  • the three sub-nozzles 13 in each set are connected to the associated sub-nozzle switching valve 24 by separate pipes 25a.
  • a common pipe 25b connects the switching valves 24 to a sub-tank 26.
  • a controller (not shown) controls the switching valves 24 to open and close in sequence from the upstream side at a predetermined timing during weft insertion. Accordingly, the sub-nozzles 13 discharge jets of compressed air in a relaying manner.
  • drum-type weft accumulators 27A and 27B are arranged on the upstream sides of the tandem nozzles 12A and 12B, respectively.
  • Each of the weft accumulators 27A and 27B includes a weft winding tube 28.

  • the inner diameter of thread guides 37 is increased so as not to block the flight of the flight promoter 41.
  • the third embodiment provides the following advantage.
  • Attachment of the flight promoter 41 to the distal end portion of the weft yarn Y is performed between the tandem nozzle 12A and the main nozzle 11 A and between the tandem nozzle 12B and the main nozzle 11 B.
  • this structure compared to a structure in which attachment of the flight promoter 41 to the distal end portion of the weft yarn Y is performed between the distal ends of the main nozzles 11A and 11 B and the weft cutter 36, swinging of the distal end portion of the weft yarn Y is reduced when the flight promoter 41 is attached to the distal end portion of the weft yarn Y, and the distal end portion of the weft yarn Y stops for a longer period.
  • more time can be used to attach the flight promoter 41 to the distal end portion of the weft yarn Y during single pivoting of the loom, and the speed of the loom can be increased.
  • the first to third embodiments are not limited to the above described configurations, but may be embodied as follows, for example.
  • the main nozzles 11A and 11 B may discharge jets of compressed air without pulling the respective weft yarns Y backward to place the flight promoters 41 and 141 in the acceleration tubes 35 of the main nozzles 11A and 11 B.
  • the set of the nozzles 11 A and 12A and the set of the nozzles 11 B and 12B may alternately insert different types of weft yarns Y.
  • weft yarns Y of the same type or of different types may be randomly inserted.
  • the air jet loom may include only one set of main nozzle 11 A and the tandem nozzle 12A.
  • the cutters 49a and 49b and the fibrillated yarn cutter 64 thermally cut the flat yarns 42 or the fibrillated yarns 59.
  • the present invention is not limited to such a structure, and the cutting may be achieved by blades.
  • the multifilament textured yarn 55 is fibrillated by electrostatic force with the electrostatic fibrillation device 57.
  • the fibrillated yarn 59 thus fibrillated is attached to the weft yarn Y.
  • a fibrillated yarn 59 that is formed in advance by fibrillating the textured yarn 55 may be used. In this case, the attaching device 40 does not require the electrostatic fibrillation device 57.
  • the flat yarn 42 and the textured yarn 55 have the length of a plurality of flight promoters 41 and a plurality of flight promoters 141 of the predetermined length, respectively.
  • the flat yarn 42 and the textured yarn 55 are cut to the predetermined length after the flight promoters 41 and 141 are attached to the distal end portions of the weft yarns Y.
  • a flight promoter that is cut to the predetermined length in advance may be used. In this case, the cutters 49a and 49b and the fibrillated yarn cutter 64 are unnecessary.
  • the flight promoter may be formed by combining the flat yarn 42 and the fibrillated yarn 59. That is, the flat yarn 42 and the fibrillated yarn 59 may be fused to the distal end portion of the weft yarn Y to sandwich the distal end portion of the weft yarn Y.
  • the method for attaching the flight promoter 41 to the distal end portion of the weft yarn Y is not limited to thermal fusion. Attachment methods such as a mechanical method may be used if necessary.
  • a weft insertion method in an air jet loom includes: attaching a flight promoter that has a greater surface area per unit weight than a weft yarn to a distal end portion of the weft yarn before weft insertion; and performing insertion of the weft yarn to which the flight promoter is attached.
