  • the yarn is cut into two yarns Y1, Y2. Then, the first clampers 5A, 5A' are manually moved to open the clamp members 5, 5'. Subsequently, the yarn Y1 is placed on the grooves 1a, 1a', arranged opposite each other, so as to extend over the tips of the grooves 1a, 1a'. On the other hand, the yarn Y2 is placed on the grooves 1b, 1b', arranged opposite each other, so as to extend over the tips of the grooves 1b, 1b'. Accordingly, the yarns Y1, Y2 are located parallel with each other.
  • Figure 4 is a schematic diagram showing how a part of the internal structure of the yarn splicing device operates, wherein the structure associated with the clamp members is omitted.
  • the lever member 3 is operated to operate the internal structure so that it changes from the state shown in Figure 4A to the state shown in Figure 4B.
  • the dotted line shown in Figure 4B represents the state shown in Figure 4A.
  • the yarn Y1 and the yarn Y2 gripped by the clamp members 5, 5' (not shown) and fixed in place respectively, are located in the open portions of the open cutters 4, 4', respectively. Then, as shown in Figure 4B, the lever member 3 is moved upwardly around the fixed shaft F2.
  • Figure 5 is also a schematic diagram showing how the above part of the internal structure of the yarn splicing device operates, wherein the structure associated with the cutter members is omitted.
  • Figure 5A corresponds to Figure 4B.
  • the lever member 3 is operated to operate the internal structure so that it changes from the state shown in Figure 5A to the state shown in Figure 5B. Further, the dotted line shown in Figure 5B shows the state shown in Figure 5A.
  • the clamp members 5, 5' grip the yarn Y1 and the yarn Y2 cut by the cutter members 4, 4', respectively, and furthermore, the projecting portion L40 provided at the upper end of the link member L4 is fitted in the concave portion 30 in the lever member 3.
  • the link member L2 remains fixed in place, while only the lever 3 is moved, because the movable blade 4b cannot be moved further.
  • the lever member 3 and the link member L2 are simply pulled by the coil spring B1, so that the lever member 3 can be moved further though the link member L2 remains fixed in place.
  • the lever member 3 is moved further upwardly around the fixed shaft F2 to rotationally move the projecting portion L40 around the fixed shaft F2, the projecting portion L40 being provided at the upper end of the link member L4, which has been fitted in the concave portion 30 in the lever member 3.
  • the movable shaft M5 and the movable shaft M4 are rotationally moved upwardly around the fixed shaft F4, the movable shaft M5 being connected to the link member L4 and the arm member 8, the movable shaft M4 being connected to the link members L3 and L3' and the arm member 8.
  • Figure 6 corresponds to Figure 5B.
  • Figure 6A is a plan view and Figure 6B is a partial sectional view.
  • the control device SS controls the operations of the adhesive supply means 6, the light irradiating means 7, the power motor DM, and the resin housing tank JT.
  • the adhesive supply means 6 is located below an abutted portion Y10 of the yarn Y1 and the yarn Y2, and a bar RB provided with a rack is attached to the adhesive supply means 6, and a gear HG attached to the power motor DM meshes with the rack of the bar RB.
  • the switch SW When the switch SW is turned on, the power motor DM is actuated to rotate the gear HG counterclockwise to move the bar RB upward, which is meshed with the gear HG. Then, a resin supply port 6A in the adhesive supply means 6 moves closer to the abutted portion Y10, and the power motor DM is stopped. In this state, the adhesive supply means 6 discharges a predetermined amount of resin through the supply port 6A to apply it to the abutted portion Y10.
  • the power motor DM is actuated to rotate the gear HG clockwise to move the bar RB downward, which is meshed with the gear HG. Accordingly, the adhesive supply means 6 returns to its original position. Then, the light irradiating means 7 irradiates the abutted portion Y10 with light to cure the resin applied to this portion. As a result, the yarn Y1 and the yarn Y2 are spliced together.
  • the clamp members 5, 5' are opened to separate the yarns Y1, Y2 from the clamp members 5, 5' to complete the splicing process.
  • the stopper St is manually moved downwardly to release the means for fixing the internal structure in place. Then, the tensile force of the coil spring B1 causes the lever member 3 to return to its original state.
  • This resin is preferably an ultraviolet curing resin.
  • the ultraviolet curing resin Before curing, the ultraviolet curing resin can infiltrate through twisted short fibers constituting the yarn owing to its permeability. It also has a sufficient elongation percentage to follow bending of the yarn after curing. Furthermore, the ultraviolet curing resin allows a curing process to be completed within a time as short as one second, and maintains fluidity before the curing process.
  • the light irradiating means preferably irradiates the resin with ultraviolet rays, which are suitable for the resin.
  • the light irradiating means 7 may be a halogen lamp or another equipment which emits light so as to be diffused but is preferably a semiconductor laser having a lens installed in a semiconductor diode, which requires less power consumption.
  • the entire yarn splicing device can be miniaturized and is thus portable. Furthermore, the reduced power consumption enables the size of the battery to be reduced, thus reducing the size of the entire device.
  • This semiconductor laser uses a lens to condense light emitted by the semiconductor diode, to emit a laser beam. The semiconductor laser thus irradiates the abutted portion Y10 with the laser beam in a pinpoint manner to instantaneously cure the resin applied to this portion.
  • the semiconductor laser preferably generates blue or purple light having a frequency range from 400 to 420 nm.
  • the battery used for this semiconductor laser consumes less power, i.e. 6 or 9 V. Consequently, the semiconductor laser generally has a reduced size and is economical.
