Note that the position of the weft cheese P in this case will be referred to as a supply standby position.

Next, the operation of this embodiment will be explained. When the cleaner 4 returns to the discharge terminal 6, the limit switch 32 is turned on to stop the drive motor 5, and the connecting piece 33 connects and fixes the cleaner 4 to the discharge device 30. At this time, the first cheese sensor 34
When the weft cheese P is not detected in the weft cheese holding section 9, the piston rod 38a of the air cylinder 38 is projected, and the weft cheese P waiting at the supply standby position is moved upward by both arm pieces 39a of the cheese catching plate 39. be lifted up.

As the weft cheese P moves upward, the bending spring 20 of the cleaner 4 is introduced into the hollow part of the core material 21 of the weft cheese P, and is contracted along the inclined surface 22a of the locking protrusion 22. Ru. When the bent portion of the bending spring 20 passes through the locking protrusion 22, the bending spring 20 expands again within the core member 21 and is pressed against the inner peripheral surface thereof. Cheese capture board 39
When the upward movement of the weft cheese P is completed, the engagement between the bending spring 20 and the locking protrusion 22 is completed, and the attachment of the weft cheese P to the weft cheese holding section 9 is completed. Thereafter, the cheese capture plate 39 is returned to its original position by the return movement of the piston rod 38a. At this time, when the cheese sensor 40 no longer detects the weft cheese P at the supply standby position, the conveyor motor 35 is activated, the belt 36 is driven, and the next weft cheese P is placed at the supply standby position.

When the weft cheese P is removed from the receiving tray 26 in each weft cheese receiving section 2, the sensor 27 no longer detects the weft cheese P, so the receiving tray 26 and the striker 29 are moved from the standby position to the required position by the action of the air cylinder 25. Placed. When the cleaner 4 holding the weft cheese P travels on the track 3, the idler roller 15 of the cleaner 4 rides over the upper half 29a of the striker 29 projected into the moving path. At this time, as the idler roller 15 moves upward, the lever 13 is rotated clockwise in FIG.
The shaft 17 is pushed down against the elasticity of the shaft 8.

Then, the spring seat 17b is further separated from the arm 12, and the bending spring 20 spreads between the spring seat 17b and the arm 12 based on its own repulsive elasticity, so that the bending state of the bending spring 20 is relaxed, and as shown in FIG. It will be slightly deflated from the swollen state shown in 3. As a result, the pressure between the bending spring 20 and the inner peripheral surface of the core material 21 is released, the expansion width of the bending spring 20 becomes smaller than the inner diameter of the upper opening of the core material 21, and the weft cheese P is moved to the weft cheese holding part 9. and falls onto the tray 26. When the weft cheese P is supplied onto the tray 26, the sensor 27 detects this, and the tray 26 and the striker 2
9 is returned from the requested position to the standby position.

When the idler roller 15 passes over the striker 29, each member of the weft cheese holding section 9 is returned to the state shown in FIG. 3 due to the repulsion of the stored force of the spring 18. That is, the lever 13 engages with the regulating protrusion 12b and is held in a horizontal state, and the shaft 17 is returned to its original position and the bending spring 20 expands in the width direction again. multiple strikers 2
9 and the receiving tray 26 are arranged at the required positions, the idler roller 15 moves over several strikers 29 projected in its movement path as the cleaner 4 moves, but the weft cheese P does not move at each position. Since the strikers 29 are not supplied, these strikers 29 continue to be arranged at the required positions, and the cleaner 4 returns to the discharge terminal 6 while repeating the idle firing of the strikers 29 by the idler roller 15.

[0023] As described above, the weft conveyance system of this embodiment has a much simpler structure than the conventional one. In particular, the system can be constructed at low cost without requiring a control system with a complicated telecommunications network between each device. In addition, since existing traveling cleaner equipment is used and it is also provided with a weft transport function, there is no need to newly provide a track exclusively for weft transport, and the present invention can be easily applied to existing equipment. It has the excellent feature of being able to
