  FIG. 3 is an enlarged side view of the rapier head 40 for wefting the composite yarn C. The rapier head 40 is provided with a pair of gripping bodies 401 and 402 constituting a gripping portion at the distal end portion of a frame body 400 formed in an elongated bar shape. The grip body 401 is integrally formed with the frame body 400, and the grip body 402 is pivotally attached to the frame body 400 by a shaft 403 and is rotatably attached. The gripping operation is performed by opening and closing the gripping body 402 with respect to the gripping body 401. A band rapier 43 is fixed to the rear end of the frame 400.

  The grip body 402 further extends from the shaft 403 toward the rear side, and the opening / closing lever 41 is formed by bending the rear end side outward. Further, a spring member 404 is provided between the rear end portion of the gripping body 402 and the frame body 400, and the spring member 404 biases the gripping body 402 so as to be in close contact with the gripping body 401. The grip body 402 rotates about the shaft 403 by the pushing operation with respect to the opening / closing lever 41 and opens between the grip body 401 and the grip body 402 releases the pushing operation of the opening / closing lever 41 so that the grip body 402 is biased by the spring member 404. , And closes in close contact with the gripping body 401.

  An opening / closing lever 42 is pivotally supported by a shaft 405 and attached to the rear end side of the frame body 400 so as to be rotatable. An operation projection 406 is projected from the end of the opening / closing lever 42 that is pivotally supported. An operation bar 407 is provided inside the frame body 400 so as to be movable along the longitudinal direction, and the rear end side is engaged with the operation protrusion 406. On the front end side of the operation bar 407, an operation lever 408 that contacts the rear end portion of the grip body 402 is pivotally supported by a shaft 409 and attached to the frame body 400 so as to be rotatable. An operation protrusion 410 is projected from the end of the operation lever 408 that is pivotally supported, and the operation protrusion 410 is engaged with the tip of the operation bar 407. A spring member 411 is provided at the rear end portion of the operation bar 407, and the operation bar 407 is constantly urged toward the front end side by the spring member 411.

  The operation protrusion 406 is rotated backward by the pushing operation with respect to the opening / closing lever 42, and accordingly, the operation bar 407 moves backward against the urging force of the spring member 411. When the operation lever 407 moves rearward, the operation protrusion 410 rotates rearward, and accordingly, the operation lever 408 operates to push the rear end portion of the gripper 402. Therefore, the gripping body 402 rotates about the shaft 403 and opens between the gripping body 401. By releasing the pushing operation of the opening / closing lever 42, the operation bar 407 moves forward by the biasing force of the spring member 411 and returns to the original state, and the operating lever 408 rotates accordingly to release the pushing state. . Therefore, the gripping body 402 is rotated by the biasing force of the spring member 404 and closes in close contact with the gripping body 401.

  As described above, the leading end portion of the composite yarn C is placed between the opened gripping bodies 401 and 402 by rotating the gripping body 402 by the pushing operation of the opening / closing lever 41 or 42 to open the gripping body 402. Can be introduced. If the pushing operation of the opening / closing lever 41 or 42 is released, the gripping bodies 401 and 402 are closed, and the composite yarn C can be gripped with certainty.

  The yarn feeding operation for grasping the composite yarn C by the rapier head 40 and drawing it into the opening region of the warp yarn A is performed by driving and controlling the sprocket drive mechanism 44. The drive control is performed by a control device (not shown) based on detection signals from the detection sensor 38 and the catch sensor 39.

  FIG. 4 is a control processing flow relating to the drawing operation of the composite yarn C. First, in order to grip the composite yarn C, the rapier head 40 starts to move forward from the position shown in FIG. 1 toward the composite yarn C (S100). Accordingly, the travel distance of the forward movement is counted by the stroke counter of the sprocket drive mechanism 44 (S101). Then, it is checked whether the count value of the stroke counter has reached the set value (S102). If the count value has reached the set value, the forward operation of the rapier head 40 is stopped (S103). The gripper located at the tip of the rapier head 40 reaches a predetermined position close to the cutter 36 by the forward movement of the rapier head 40.

  Next, the holding operation of the composite yarn C by the holding body is performed (S104), and the backward operation of the rapier head 40 is started (S105). Along with this, the moving distance of the backward movement is counted by the stroke counter of the sprocket drive mechanism 44 (S106). Then, it is checked whether or not the count value of the stroke counter has reached the set value (S107). When the count value has reached the set value, the backward operation of the rapier head 40 is temporarily stopped (S108). The gripper located at the tip of the rapier head 40 reaches a predetermined position close to the catch sensor 39 by the backward movement of the rapier head 40.

  Next, it is checked whether or not the catch sensor 39 has detected the composite yarn C (S109). If the catch sensor 39 has not detected the composite yarn C, the composite yarn C has not been gripped by the rapier head 40. As a result, a catch-miss process is performed (S110). When the catch sensor 39 detects the composite yarn C, the backward operation of the rapier head 40 is resumed (S111), and it is checked whether or not the detection sensor 38 has detected the passage of the electronic component (S112). When the passage of the electronic component is detected, the backward movement of the rapier head 40 is stopped (S113).

  The composite yarn C is gripped by the processing described above, and the pull-in operation is performed reliably. And the electronic component carried by the composite yarn C pulled in based on the detection signal of the detection sensor 38 can be accurately positioned. In the processing described above, the detection sensor 38 detects the passage of the electronic component and stops the backward movement of the rapier head 40. However, after the detection sensor 38 detects the passage of the electronic component, the detection sensor 38 stops after moving back a predetermined distance. You may process so that it may set a position.

  FIG. 5 is a chart showing the operation timing of each member regarding the weft insertion operation of the composite yarn C. 6 to 11 are a side view and a top view showing the operation of each member at each timing. At the timing T0, as shown in FIG. 6, the leading end of the composite yarn C is set at the cutting position of the cutter 36 and is gripped by the supply gripper 34. The rapier head 40 is set at a standby position away from the opening area of the warp A, and the driving gripper 37 is set in an open state.

  At the timing T1, as shown in FIG. 7, the rapier head 40 is moved throughout the body and introduced into the opening region, and the gripping body at the tip moves to a position close to the cutter 36 that grips the tip of the composite yarn C. When the rapier head 40 moves to the gripping position, the opening / closing lever 42 is set to a position facing the driving rod 45, and the opening / closing lever 42 is pushed by the driving rod 45. When the opening / closing lever 42 is pushed in, the gripping body is opened, and the tip of the composite yarn C is introduced between the gripping bodies. When the drive rod 45 releases the pushing operation of the opening / closing lever 42, the gripping body is closed again and the composite yarn C The tip is gripped by the rapier head 40.

  At timing T2, as shown in FIG. 8, the supply gripper 34 opens and moves so that the rapier head 40 is retracted and pulled back, and the composite yarn C is drawn into the opening region. The rapier head 40 is temporarily stopped after a predetermined distance, and the catch sensor 39 detects whether the composite yarn C is gripped. After the composite yarn C is detected, the backward movement of the rapier head 40 is restarted, and the presence or absence of the electronic component is detected by the detection sensor 38. When the passage of the electronic component is detected, the backward movement of the rapier head 40 is stopped.

  At timing T3, as shown in FIG. 9, the yarn feeding operation of the composite yarn C is stopped, and the driving gripper 37 grips the composite yarn C. The supply gripper 34 also operates to grip the composite yarn C.

  At timing T4, as shown in FIG. 10, the cutter 36 performs the cutting operation of the composite yarn C. Further, the rapier head 40 is returned to the standby position, the opening / closing lever 41 is set to a position facing the driving rod 46, the driving rod 46 pushes the opening / closing lever 41 to open the gripper of the rapier head 40, and the tip of the composite yarn C is gripped. Cancel the operation.

  At timing T5, as shown in FIG. 11, the driving gripper 37 is moved so that the cut composite yarn C is driven between the opened warps.

  Since the composite yarn C is wefted in operation as described above, weaving can be performed while suppressing damage to the composite yarn C.
