Definitions

  • the present invention relates a multiple yarn guide.
  • the Unexamined Japanese Patent Application Publication (Tokkai) No. 2005-179807 discloses an interlacing device including a guide that regulates and holds a path of a traveling yarn. That is, as shown in Figure 3 of the Unexamined Japanese Patent Application Publication (Tokkai) No. 2005-179807 , a plurality of cylindrical regulating guides G1 regulating the yarn path are arranged in a line in front of and behind a fluid processing section that carries out a process of interlacing yarns with each other. Moreover, a bar guide G2 shaped like a round bar is provided so as to stride over the plurality of regulating guides G1. The adjacent regulating guides G1 and the round bar-shaped bar guide G2 form the yarn path.
  • the Unexamined Japanese Patent Application Publication (Tokkai) No. 2008-504462 discloses yarn guide beams arranged in front of and behind a nozzle block that processes a filament yarn. As shown in Figure 2 of the Unexamined Japanese Patent Application Publication (Tokkai) No. 2008-504462 , the yarn guide beam is shaped like a comb in association with a flow of a given number of yarns.
  • the configuration in the Unexamined Japanese Patent Application Publication (Tokkai) No. 2005-179807 requires the round bar-shaped bar guide G2 to provide the yarn path.
  • the configuration involves a large number of components and is not easy to assemble.
  • the comb shape employed in the Unexamined Japanese Patent Application Publication (Tokkai) No. 2008-504462 generally tends to be readily damaged.
  • US 3,734,374 discloses an assembly for use in guiding continuous lengths of material, the assembly being constructed of a plurality of guide members, each having an integrally formed body defining oppositely directed material guiding notches.
  • the guide members are constructed so that the two oppositely directed notches are located in spaced parallel planes, and detailed in location relative to each other when assembled whereby one material guiding notch of one guide member is coaxially aligned with an oppositely directed material guiding notch of an adjacent guide member to define a material guiding passageway.
  • the two aligned notches are axially spaced relative to each other to define a material threading passageway which communicates with and is angularly disposed relative to the material guiding passageway to permit a length of material to be inserted into or removed from the material guiding passageway.
  • the guide members also include formed surfaces adapted to interlock with complementary surfaces on adjacent guide members when supported in an assembled juxtapositioned relationship with each other.
  • a channel-shaped support member is provided for supporting the guide members in transverse alignment and in juxtaposition relative to each other so that the formed surfaces are in interlocking relationship.
  • a spacer means is operatively associated with the channel-shaped support member so that the guide members can be transversely adjusted to a selected set position and can be spaced relative to each other to permit selected guide members to be independently added or removed.
  • a main object of the present invention is to provide a multiple yarn guide which is easy to assemble owing to a reduced number of components required and which is unlikely to be damaged.
  • An aspect of the present invention provides a multiple yarn guide configured as described below. That is, the multiple yarn guide includes a plurality of guide members arranged in a line. A yarn accommodating space in which a yarn is accommodated is formed by a pair of the adjacent guide members.
  • this configuration eliminates the need for the round bar-shaped bar guide G2. This reduces the number of components required, resulting in easy assembly. Furthermore, this configuration is less likely to be damaged than the comb-shaped yarn guide beam disclosed in Figure 2 of Unexamined Japanese Patent Application Publication (Tokkai) No. 2008-504462 . Moreover, if any of the guide members is damaged, only the damaged guide member needs to be replaced with a new one. This enables a reduction in maintenance costs.
  • the above-described multiple yarn guide is configured as follows. That is, the multiple yarn guide is configured to allow the number of the plurality of guide members to be increased and reduced. This configuration enables a change in the number of the yarn accommodating spaces.
  • the multiple yarn guide is further configured as follows. That is, the multiple yarn guide includes an elongate member. Each of the guide members engages with the elongate member so as to be supported by the elongate member. According to this configuration, the simple arrangements can be used to arrange the plurality of guide members in a line and to increase and reduce the number of the plurality of guide members.
  • the multiple yarn guide is further configured as follows. That is, the yarn accommodating space is formed by the pair of the adjacent guide members. Compared to the case in which the yarn accommodating space is formed in each of the guide members, this configuration allows the shape of the guide member to be simplified. Furthermore, the simplified shape of the guide member contributes to reducing the pitch of the yarn accommodating spaces and thus making a facility with the multiple yarn guide compact.
  • the multiple yarn guide is further configured as follows. That is, a planar direction of mating surfaces of the pair of the adjacent guide members is inclined to a traveling direction of the yarn accommodated in the yarn accommodating space. This configuration prevents the yarn from falling into a gap between the mating surfaces. Thus, manufacturing costs can be reduced in connection with the processing accuracy of the mating surfaces.
  • the multiple yarn guide is further configured as follows. That is, a first projecting portion and a second projecting portion are formed on each of the guide members, the second projecting portion regulating movement of the yarn in a direction perpendicular to the direction of the line of the guide members.
  • the yarn accommodating space is formed by a slit formed by a pair of the adjacent first projecting portions, and the second projecting portion. According to this configuration, the simple arrangements can be used to support the yarn in three directions.
  • the multiple yarn guide is further configured as follows. That is, an inclination between the planar direction of the mating surfaces and the traveling direction of the yarn is configured to be changeable. With this configuration, a change in inclination increases or reduces a distance between the paired adjacent first projecting portions. Thus, according to this configuration, the slit width of the slit can be changed.
  • the multiple yarn guide is further configured as follows. That is, a pawl portion is formed on at least one of the pair of the adjacent guide members to prevent the yarn from slipping out from the yarn accommodating space. According to this configuration, the simple arrangements can be used to prevent the yarn from slipping out from the yarn accommodating space.

  • a through-hole 41 extending along the traveling direction Yd of the filament yarn Y is formed in a center, in a front view, of the guide portion 21, projecting perpendicularly upward from the base portion 20.
  • the slit 24 is engraved in the guide portion 21 so as to extend from an upper end of the guide portion 21 toward the base portion 20 and reach the through-hole 41.
  • the slit 24 is inclined at about 45 degrees to the traveling direction Yd of the filament yarn Y in the plan view in Figure 15B .
  • a main component of the guide portion 21 is a pair of fourth projecting portions 40 each shaped substantially like a trapezoid or a triangle in the plan view in Figure 15B .
  • a conical tapered surface 42 surrounding the through-hole 41 is formed in each of the fourth projecting portions 41. This reduces a contact distance between an inner wall surface of the through-hole 41 and the filament yarn Y.
  • a pawl portion 43 is formed opposite the base portion 20 across the through-hole 41 as a result of the formation of the through-hole 41 and the slit 24.
  • the pawl portion 43 is formed so as to cover the through-hole 41 in a direction opposite to a projecting direction of the fourth projecting portion 40.
  • a guide surface 40a is further formed which is curved smoothly from the pawl portion 43 toward an upper end of the fourth projecting portion 40.
  • the guide piece 15 according to the present embodiment is symmetric with respect to a point in a plan view.
  • the yarn accommodating space S in the multiple yarn guide 9 is formed in each of the guide pieces 15 as shown in Figure 14 .
  • the yarn accommodating space S is formed by the through-hole 41.
  • the pawl portion 43 fulfils a function of preventing the filament yarn Y accommodated in the yarn accommodating space S formed by the through-hole 41 from slipping out from the yarn accommodating space S.
  • the filament yarn Y may be inserted into the slit 24 in the direction of an arrow denoted by reference numeral N in Figure 15A .
  • the slit 24 is inclined to the traveling direction Yd of the filament Y, as is the case with the second embodiment.
  • the filament yarn Y is bent once along the inclination of the slit 24. Flapping of the filament yarn Y traveling through the yarn accommodating space S under a desired tension is regulated by an inner wall surface of the through-hole 41. In particular, flapping of the filament yarn Y in the vertical direction is effectively regulated by the pawl portion 43.
  • the multiple yarn guide 9 is configured as follows. That is, the yarn accommodating space S is formed in each of the guide pieces 15. This configuration allows the yarn accommodating space to be formed away from the mating surfaces F of the pair of the adjacent guide pieces 15.
  • the yarn guide 9 is further configured as follows. That is, the slit 24 and the pawl portion 33 are formed in each of the guide pieces 15, the slit 24 allowing the yarn accommodating space S to communicate with an exterior, and the pawl portion 33 preventing the filament yarn Y from slipping out from the yarn accommodating space S.
  • This configuration simplifies the arrangement for enabling the filament yarn Y to be inserted into the yarn accommodating space S and the arrangement for preventing the filament yarn Y from slipping out from the yarn accommodating space S.
  • the multiple yarn guide 9 is applied to the melt-spinning and drawing device 100.
  • the application of the multiple yarn guide 9 is not limited to the melt-spinning and drawing device 100.
  • the yarn guide 9 is applicable to a textile machine that handles multiple yarns in a narrow space. Possible textile machines other than the melt-spinning and drawing device 100 include, for example, a warping machine.
  • the yarn is the filament yarn Y by way of example.
  • the multiple yarn guide 9 is applicable to yarns other than the filament yarn Y.
  • the yarns other than the filament yarn Y include spun yarns such as a cotton yarn and a wool yarn.
  • the multiple yarn guide 9 is provided close to the interlacing device 8 as shown in Figure 1 .
  • the yarn guide 9 may be located away from the interlacing device 8.
  • the number of the filaments yarns Y is much smaller than that of the guide pieces 15 disposed, in, for example, Figure 2 . This is simply for convenience of description.
