Then, the tray in which the tubing of the type for the second winding section 4 is inserted is selected, and the predetermined tray is taken into the second branch line 18. The tray is the second for the second winding section 4.
It is sent to the output device 19 and processed for output, returned to the supply line 1 again, the tray is selected by the fourth selection device 20, and sent to the second intake line 10. The tubular yarn sent to the second take-in line 10 is sent to the empty bobbin carry-out line 12 by the take-up machine constituting the second take-up section 4 and the empty bobbin which has finished winding.

Various devices are used as the output device, for example, a device as shown in FIG. That is, in this apparatus, the finely spun yarn 21 is transferred in the direction of the arrow on the transport path 22 while being inserted into the tray T, and reaches the receiving position A of the dispensing device. Tray receiving portions 25 provided at a constant pitch on the rotating plate 24 of the feeding device
The yarn 21a received by the
The station B is reached with intermittent rotation in six directions. In the station B, a cutter device 30 for unwinding and cutting the bunch winding 29 wound around the lower end of the tubular thread is arranged, and the tubular thread 21B is rotated by a friction roller in a direction for unwinding the wound thread. ing.

Further, a searcher 40 is provided at this portion to scoop out the wound yarn end that is pressed against the tubular yarn 21C. Further, in the station D, a yarn end suction / unwinding device 34 for sucking and unwinding the yarn end in the free state is arranged, and is constituted by, for example, a suction mouth 36 having a slit 35. In this position, the thread 21
The friction roller 37 rotates the roller d in the unwinding direction 32. Next, at the station E, a mechanism is provided in which the yarn drawn out from the tubular yarn is cut into a certain length and the yarn end is inserted into the central hole 38 of the tubular yarn 21e. In the station F, it is detected whether or not the yarn end has been laid out, and the tubing 21S that has been laid out is sent to the transport path 7 and is transported in the direction of the arrow 28. The unthreaded yarn is returned to station A through stations G and H, and the above steps are repeated.

As the dispensing device, various conventionally used devices can be used, and among the various processes of the dispensing device described above, appropriate processes can be omitted.

Further, as the output device, in addition to the above-described system of performing the output processing by circulating on a plane, a twist conveyor 40 as shown in FIG. 3 is used, and it is conveyed upright on the supply conveyor 1. It is also possible to twist the tubing 41 together with the tray so that the tubing is laid sideways and conveyed to the dispensing device 42.

In the twist conveyor 40, the tray on which the tube yarn conveyed by the belt 43 in the supply line 1 is inserted is transferred to the surface of the conveyor belt 45 while reversing the conveying direction by the reversing guide 44, and the tray is transferred. The tray is guided sideways by the guide rails 46 that guide the upper surface, and is guided to the side surface of the conveyor belt 45, and is guided upward through the side peripheral surface of the belt pulley 50. In this state, it is returned to the supply conveyor 1 by the twist conveyor 52 through the transport path 51 and an arbitrary lead-out process.

In the above device, since the output device can be arranged in the horizontal direction, the space in the factory can be effectively used,
It is possible to provide a large number of dispensing devices in a small space even if the number of types of yarn is increased.

By using the above-mentioned twist conveyor, as shown by 4 in the figure, it is also possible to make a portion for transporting the tubing vertically, and various kinds of lead-out processing are performed at this vertical transport portion. As a result, it becomes possible to use almost any conventional processing device that carries out the yarn ejection while conveying the conventional yarn in a vertical state.

When using the above-mentioned various devices for performing the ejection processing on the vertical surface by using the twist conveyor, as shown in FIG. 5, the branch line 14 from the supply line 1 is not drawn to the outside, but the direct intake line 14 is used. It is possible to use the conventional line configuration for transporting the sheet to the substrate as it is and to provide the feeding device 55 on the branch line, thereby simplifying the line configuration.

In the embodiment shown in FIG. 1, the tube yarn treated by the dispensing device 15 is returned to the supply line 1 and transferred to the intake line by the second sorting device or the like. It is also possible to directly feed the tubing treated in (1) to the take-in lines 9 and 10 through the branch line passing above or below the feed line 1.
