After the yarn end of ) (Pb) is wound around the upper end of the guide vibrator (35), it is returned to the circulation line (16) as an actual yarn feeding tray (30a). The underpainting yarn package (Ph) and the overlapping yarn package (Pa) are alternately supplied to the yarn feeding exchange device (20), and the upper and lower yarn feeding packages are identified and supplied. Therefore, the exchange device (20) sequentially changes the yarn feeding packages (Pa) (Pb
) by supplying the underpainting thread package (pb)
is placed on the lower side, and the thread package (Pa) is placed on the upper side.

In other words, in order to eliminate the waste of remaining yarn in the underlined yarn package due to the difference in unwinding tension between the upper and lower yarn supply packages, the underlined yarn package (pb) is better than the overlined yarn package (pb).
The yarn amount is set smaller than Pa).

Next, the structure of the above-mentioned pick-out device (21) will be explained based on FIG. 1. Upper and lower yarn feeding package (PA) (Pb
) is provided with a suction pipe (51) having a trumpet-shaped opening (50). The opening (50) of the suction pipe (51) and the yarn feeding package (Pa) (Pb)
A guide bar (53) that moves up and down about a fulcrum (52) is installed between them. That is, the guide bar (53) is fixed to the tip of the link (55) slidably inserted into the shaft (54), and the guide bar (53) and the shaft (54) are connected to each other.

With the above configuration, with the lever (73) pulled upward (74) against the spring (71), the chuck (65) can be moved into the guide pipe (
35) Insert from above.

After insertion, when the upward force (74) of the lever (73) is released, the slider (7) is moved by the force of the spring (71).
0) moves downward, and the cap black 8) and slider (
70) presses the deformable ring body (69) from above and below. Due to the pressing force, the deformable ring body (69) is deformed in the outward direction of the circumference and chucks the guide pipe (35) from the inside thereof. Since the inside of the guide pipe (35) is chucked, there is no need to provide an extra length at the upper end of the guide pipe (35) for a portion to be gripped by the chuck. Therefore, the overall height of the guide pipe (35) can be kept low. The technical concept of stacking the yarn feeding packages in two tiers increases the overall height and increases the transport and
There is an inherent problem in that it tends to cause problems during transfer, etc., so being able to lower the height would be a great advantage. Furthermore, the yarn end is lightly wound around the upper end of the guide pipe (35), so that the yarn end is not affected at all when the inner chuck (65) is performed.

In the above embodiment, the yarn feeding packages are transferred to the double-twisting machine in a two-tiered state, and are supplied as they are to the double-twisting machine, which greatly simplifies the supply process. At the same time, it is possible to eliminate clumsiness in which the upper and lower yarn feeding packages are reversed during yarn feeding.

In the above embodiment, the present invention is applied to a package to be supplied to a two-stage yarn feeding type double twisting machine, and the two yarn ends of the two yarn feeding packages are wrapped together around the guide pipe. . The two packages inserted into the guide pipe are fed to the double twisting machine in their set state, and the two yarn ends can be processed at the same time, which is efficient.

Note that the "non-yarn layer portion" at the upper end of the yarn feeding package may be either a paper tube portion or the upper end portion of the guide pipe inserted into the yarn feeding package described above.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is possible to transfer the yarn supply package without floating yarn ends.
There is no possibility that the floating yarn ends become entangled with surrounding members or that the floating yarn ends are unraveled one after another.
