Definitions

  • the invention relates to a synthetic yarn splicer.
  • Patent Literature 1 JP H10-17214 A
  • a starting end and a terminating end of two synthetic yarns are aligned in the opposite directions to be drawn into an air nozzle, both side portions outside the air nozzle of the drawn yarn end are pressed down, the pressed both side portions are moved into the air nozzle, the aligned yarn end is loosened inside the air nozzle, and the yarns are spliced by an air flow inside the air nozzle.
  • the document JP S60 144281 A describes a method of splicing multi-filament yarns and a splicing device having a splicing head and a pair of yarn gripping receivers, wherein the yarns are opened by an airstream within a yarn reservoir of the splicing head to be entangled together.
  • the synthetic yarn splicer is used to splice a terminating end of a yarn of one supply bobbin and a starting end of a yarn of the other supply bobbin in, for example, a yarn winding machine for winding synthetic fibers.
  • the yarn winding machine the yarn is wound around a bobbin while applying a tension to the yarn to form a package. For that reason, an entangled portion obtained by splicing the yarns by the synthetic yarn splicer is pulled while a tension is applied thereto.
  • the yarn winding machine when the entangled portion is unwound during the winding operation, the winding operation must be temporarily stopped and hence the production efficiency is lowered. For that reason, there is a demand for forming an entangled portion having a tensile elongation capable of withstanding a winding tension in the synthetic yarn splicer.
  • An aspect of the invention is to provide a synthetic yarn splicer capable of suppressing a decrease in tensile elongation of an entangled portion.
  • a synthetic yarn splicer is a synthetic yarn splicer according to claim 1 that splices one yarn and the other yarn formed of synthetic fibers, including: a yarn splicing portion that includes a passage which forms a space through which the one yarn and the other yarn are insertable, a slit which communicates with the passage and allows the one yarn and the other yarn to be insertable into the passage from an insertion direction orthogonal to a penetration direction of the passage, and an injection hole which opens to the passage and injects a fluid; and a pair of clamping mechanisms that is provided at a position interposing the passage of the yarn splicing portion in the penetration direction of the passage and clamps each of the one yarn and the other yarn inserted through the space, in which the passage has a circular shape when viewed from the penetration direction of the passage, in which the injection hole is disposed on a first line which is orthogonal to the penetration direction of the passage and the insertion direction and passes through a center of the passage, in which the pair
  • a fluid which is injected from the injection hole collides with the inner peripheral surface of the passage at a position facing the injection hole and flows to the slit and to the side opposite to the slit along the inner peripheral surface.
  • the fluid flowing to the slit can flow to the outside of the passage through the slit. For that reason, when the line connecting the clamping position is located in an area at the side of the slit with respect to the first line, a fluid does not effectively act on one yarn and the other yarn and one yarn and the other yarn are not appropriately swayed in the passage. Accordingly, there is a possibility that the entangled portion is not appropriately formed.
  • the line connecting the clamping position is located in an area at the side of the injection hole with respect to the second line, there is a possibility that the fluid injected from the injection hole is directly sprayed to one yarn and the other yarn. Accordingly, since the fluid does not effectively act on one yarn and the other yarn and one yarn and the other yarn are not effectively swayed in the passage, there is a possibility that the entangled portion is not appropriately formed.
  • the pair of clamping mechanisms clamps one yarn and the other yarn so that the line connecting the pair of clamping positions of one yarn and the other yarn is located in a predetermined area of the passage when viewed from the penetration direction of the passage.
  • the predetermined area is an area which is located at the side opposite to the slit with respect to the first line and is located at the side opposite to the injection hole with respect to the second line following the insertion direction and passing through the center.
  • the entangled portion can be appropriately formed.
  • a decrease in tensile elongation of the entangled portion can be suppressed.
  • the predetermined area is an area between a first circular arc which is distant from the center by 0.5 mm and a second circular arc which is distant from the inner peripheral surface of the passage by 0.3 mm.
  • a diameter of the passage may be equal to or larger than ⁇ 3.5 mm and equal to or smaller than ⁇ 6.0 mm and a diameter of the injection hole may be equal to or larger than ⁇ 1.0 mm and equal to or smaller than ⁇ 1.3 mm.

  • each of the pair of clamping mechanism may include a clamping portion including a pair of clamping members clamping each of the one yarn and the other yarn.
  • the clamping position of each of one yarn and the other yarn can be accurately set. Accordingly, in the synthetic yarn splicer, the line connecting the pair of clamping positions can be reliably located in a predetermined area.
  • each of the pair of clamping mechanisms may include a support portion supporting the clamping portion and the support portion may be disposed between the yarn splicing portion and the clamping portion and may include a contact surface contacting the one yarn and the other yarn clamped by the clamping portion.
