  • the angle between the guide surface 83 and the opening surface 67f is preferably larger than zero degrees but equal to or smaller than 45 degrees and more preferably equal to or larger than 20 degrees but equal to or smaller than 45 degrees.
  • the guide surface 83 is constructed as one inner wall surface of the guide groove 84 formed in the flexure guide member 81.
  • the yarn 21 is guided in the state in which the yarn 21 is in the groove, the path at the time the yarn 21 is pulled out from the untwisting pipe 66 can be stabilized. As a result, the yarn 21 can be pulled while forming the stable bending point 21b.
  • the leading-in guide surface 87 that guides the yarn 21 to the guide surface 83 while contacting the yarn 21 whose yarn end has been sucked into the untwisting pipe 66 and connects to the guide surface 83.
  • the yarn 21 can be smoothly guided to the guide surface 83 by using the sucking action of the untwisting pipe 66, the yarn 21 can be bent surely.
  • the flexure guide member 81 includes the through-hole 82 that communicates to the inside of the untwisting pipe 66.
  • the guide surface 83 connects to the inner wall of the through-hole 82.
  • the yarn 21 with the yarn end thereof sucked in the untwisting pipe 66 via the through-hole 82 can be suitably guided by the guide surface 83.
  • An automatic winder includes the yarn joining device 41.
  • an automatic winder that can favorably perform the yarn joining of the yarn having elasticity can be realized.
  • the yarn 21 having elasticity used in the winder unit 1 is not particularly limited.
  • the spandex yarn can be used as the yarn 21.
  • the shape of the guide groove 84 formed in the flexure guide member 81 can be changed appropriately.
  • the flexure guide member 81 can be detachably attached to the yarn joining device 41. By adopting this configuration, it is possible to handle both the ordinary yarn and the special yarn having elasticity with a simple operation.
  • a wall of the flexure guide member 81 located opposite to the guide surface 83 across the guide groove 84 may be omitted.
  • the guide groove 84 is not provided and the yarn 21 is guided by the guide surface 83.
  • the movement of the yarn can be restricted by making the surface of the guide surface 83 rough. This leads to enhancing the frictional force for suppressing sudden shrinking of the yarn 21.
  • the yarn joining device includes two untwisting pipes, a yarn joining section, and a yarn guide section corresponding to each of the untwisting pipes.
  • the untwisting pipe is configured as a hollow member and the untwisting pipe untwists a yarn end that entered therein by applying air current to the yarn end.
  • the yarn joining section has an air chamber in which yarn joining of untwisted yarn ends is performed by applying air current to the yarn ends.
  • a guide surface that guides the yarn end pulled out from the corresponding untwisting pipe before the yarn end arrives in the air chamber is formed in the yarn guide section.
  • An opening from which the yarn end pulled out from the untwisting pipe is pushed into the air chamber is formed in the yarn joining section.
  • the guide surface When seen from a length direction of the untwisting pipe, the guide surface extends from the untwisting pipe and makes a first angle that is larger than zero degrees with respect to an opening surface of the opening. The first angle is smaller than a second angle that an imaginary line connecting a center of the untwisting pipe and an edge of the opening of the yarn joining section that is nearest to the untwisting pipe makes with the opening surface.
  • the yarn guide section can guide the yarn in the air chamber while bending the yarn at the edge of the guide surface. Therefore, in the process of pulling the yarn from the untwisting pipe, the yarn can be prevented from suddenly shrinking because of the friction at the bending point. As a result, because the yarn end can be surely guided to the air chamber, failure of the yarn joining can be prevented. Moreover, since the friction is generated because of the bending of the yarn, in comparison to a configuration that addresses the issue of shrinking of the yarn by putting the yarn in a slit, the frictional force does not change with the thickness of the yarn, and the shrinking of the yarn can be suppressed stably.
  • the first angle between the guide surface and the opening surface of the opening is preferably larger than zero degrees but equal to or smaller than 45 degrees.
  • the frictional force that is sufficient to prevent the sudden shrinking of the yarn can be obtained by bending the yarn relatively more.
  • the first angle between the guide surface and the opening surface of the opening is preferably equal to or larger than 20 degrees but equal to or smaller than 45 degrees.
  • the guide surface is constructed as one inner wall surface of a guide groove formed in the yarn guide section.
  • the yarn is guided in the state in which the yarn is in the groove, the path at the time the yarn is pulled out from the untwisting pipe can be stabilized. As a result, the yarn can be pulled while forming the stable bending point.
  • the yarn guide section is formed a leading-in guide surface that guides the yarn to the guide surface while contacting the yarn whose yarn end has been sucked into the untwisting pipe and connects to the guide surface.
  • the yarn can be smoothly guided to the guide surface by using the sucking action of the untwisting pipe, the yarn can be bent surely.
  • the yarn guide section includes a through-hole that communicates to the inside of the untwisting pipe.
  • the guide surface connects to an inner wall of the through-hole.
  • the yarn with the yarn end thereof sucked in the untwisting pipe via the through-hole can be suitably guided by the guide surface.
  • a textile machine including the above yarn joining device is provided.
  • the yarn joining device can be used, for example, as a yarn joining device of an air spinning machine, instead of using the same in the automatic winder.
