From left to right, they are referred to as 0th stage (0st), 1st stage (1st), 2nd stage (2st), and 3rd stage (3st).

The 0th stage (0st) is provided with surface layer releasing means B for releasing the outermost layer winding 3 of the package P by suction. The first stage (1st) is provided with yarn tying means C for tying the released yarn end to the outer periphery of the package P. The second stage (2st) is provided with a bunch winding releasing means D for releasing the bunch winding 1 wound around the paper core K of the package P. In the third stage (3st),
Bunch processing means E for locking the released bunch thread end 1a in the slit S of the paper tube K is provided.

A side view of the 0th stage (0st) is shown in FIG. At the 0th stage (0st), the outermost layer winding 3 of the package P is sucked and released. 10 in the figure
Is a suction pipe for sucking the bar winding 3 of the outermost layer of the package P. The suction pipe 10 is movable in the axial direction of the package P and also in the radial direction. The operation of this suction pipe 10 is shown in FIGS. As shown in FIGS. 6A and 6B, when the suction pipe 10 moves in the direction of arrow 11, the suction port 10a of the pipe 10 sucks the yarn end 5 of the rod winding 3. After that, FIG.
As shown in (a) and (b), the suction pipe 10 is moved to the axial end portion of the package P. Then, the bar winding 3 is axially unwound from the end of the package P, and the suction pipe 1
It is released while forming the balloon 12 to the suction port 10a of 0. When the thread of the rod winding 3 is used up, the balloon 12 is formed of the thread of the main winding 2 as shown in FIGS. The yarn of the main winding 2 is wound around the paper tube K over a traverse range of a predetermined length. Therefore, in this case, the yarn end of the balloon 13 moves around the outer periphery of the package P while the package P
Reciprocate on both ends of. At this time, the yarn end of the balloon 13 is
Balloon sensor 1 provided close to the outer periphery of the package P

A side view of the first stage (1st) is shown in FIG. In the first stage (1st), after the yarn end 16 of the outermost layer of the main winding 2 after releasing the winding 3 is sucked and captured by the suction port 17a of the suction pipe 17, two loops are provided on the outer periphery of the package P. And make a knot with those comrades. The outline of this thread knot will be described with reference to FIGS. 10 (a) to 10 (f). First, as shown in FIG. 10 (a), the thread hooking guide 1
8 captures the yarn between the suction port 17a of the suction pipe 17 and the package P to form an inner ring 19 and an outer ring 20. Between the yarn hooking guide 18 and the package P, a building device 21 for tying a yarn is arranged. FIG. 10B shows a state in which the inner ring 19 is dropped on the building device 21, and the hook 22 is formed on the outer ring 20 in the building device 21. As shown in FIG. 10C, the hook ring 22 is passed through the inner ring 19 by the building device 21, and in this state, the inner ring 19 is removed from the building device 21 and dropped into the package P. At this time, the inner race 19 is in a state of engaging with the yarn 23 extending from the hook 22 to the yarn hooking guide 18.
In this state, when the thread knotting guide 24 is rotated in the direction of the arrow shown in the figure, the inner ring 19 is tightened to approximately the same circumference as the package P, as shown in FIG. Next, the thread hooking guide 18 guides the thread 23 so as to come under the hook 22 and, in that state, as shown in FIG.
A thread is tied by making a threaded ring 23a on the hook and passing the threaded ring 23a through the hook 22. Then, the knot is tightened by holding the thread knot guide 24 at the rotation position shown in FIG. 10 (e) and rotating the package P in the direction of the arrow shown while supporting the knot so that the knot does not move. This package P is rotated by the chucker 2 shown in FIG.
This is achieved by inserting and fixing the paper tube K of the package P into the sheet 5, and rotating the chucker 25. Thereafter, the yarn end at the winding end is appropriately cut by the heat cutter 26 (see FIG. 9) to complete the yarn knot 6 as shown in FIG. 10 (f).

In the first stage (1st), the bunch winding 1 wound around the end of the paper tube K of the package P is moved to the main winding 2 side of the package P by the yarn feeding roller 27 shown in FIG. , An operation of preparing to release the bunch winding 3 is performed. This is shown in FIGS. As shown in FIG. 11, the nip point N of the yarn bunched around the paper tube K of the package P is the uppermost layer (outermost layer), and the yarn start end of the lowermost layer (innermost layer) is formed on the paper tube K. It is fitted in the slit S formed. Therefore, the yarn feeding roller 27 is
The yarn of the bunch winding 1 wound on the slit S is moved from the yarn near the nip point N to the package P side in order. That is, as shown in FIG. 11, the tip 27a of the yarn feeding roller 27 contacts the circumferential surface of the paper tube K between the bunch winding 1 and the nip point N, and in that state, the direction opposite to the bunch winding 1 winding direction. Is revolved as shown by the arrow in the figure.
As a result, the tip 27a of the yarn feeding roller 27 catches the yarn extending from the nip point N to the bunch winding 1, and the yarn is sequentially screwed to the position of the tip 27a as shown in FIG. As a result, as shown in FIG. 13, the starting end of the thread fitted in the slit S is exposed on the surface of the paper tube K.

A side view of the second stage (2st) is shown in FIG. At the second stage (2st), the bunch thread wound around the paper core K of the package P is released, that is, the thread fitted into the slit S of the paper core K (see FIG. 13).
The starting point of is released. Figure 15

As shown in FIG. 15, first, the cone-shaped package retainer 28 is moved so as to engage with the end of the paper tube K, and the tip 29a of the thread breaking roller 29 contacts the surface of the paper tube K near the slit S. To be done. In that state, the yarn breaking roller 29 is revolved in the winding direction of the bunch winding 1. As a result, the tip 29a of the yarn breaking roller 29 catches the yarn between the nip point N and the bunch yarn start end fitted in the slit S, and the yarn is threadedly moved toward the end of the paper tube K. .. As a result, the bunch thread is loosened. The loosened thread is the paper tube K
Port 28a of the package retainer 28 engaged with the end of the
Is more aspirated. Then, as shown in FIG. 16, the package retainer 28 is moved so as to be separated from the end of the paper tube K. Then, as shown in FIGS. 17 (a) and 17 (b), the nip point N
The yarn YN from and the yarn YS fitted in the slit S are pulled out. In that state, as shown in FIG. 18, the yarn YS,
Pull down the chuck ring 30 from above the YN (see FIG. 1).
4). This pulling down is performed until the cone portion 31 of the chuck ring 30 is aligned with the axis of the paper tube K, as shown in FIG. Then, the chuck ring 30 is moved so that the cone portion 31 engages with the end portion of the paper tube K, as shown in FIGS. Then, rotate the thread clamp lever 32 (see FIG. 14) in the direction of the arrow in the drawing to
The lever 32 presses the thread of the suction port 28a of the package presser 28. In that state, as shown in FIGS.
When the chuck ring 30 is rotated, the thread chuck lever 33 provided on the chuck ring 30 engages only with the thread YS from the slit S and captures the thread YS.
As shown in (a) and (b), the yarn YS engaged with the slit S is pulled out. The pulled-out yarn is sucked and removed from the suction port 28a of the package retainer 28.

A side view and a front view of the third stage (3st) are shown in FIGS. 23 (b) and 23 (a). In this third stage (3st),
The thread YN pulled out from the slit S of the paper tube K is cut into an appropriate length, and the thread YN is engaged with the slit S of the paper tube K again. This is shown in FIG. As shown in FIG. 24, the package retainer 28 of the second stage (2st)
The yarn YN grasped by the yarn gripping lever 32 (see FIG. 14) at the suction port 28a of the
3), and is deflected so that the direction of the slit S of the paper tube K coincides with that of the slit S of the paper tube K. In the state shown in FIG. 24, the paper tube K
The yarn YN is locked in the slit S of the paper tube K by chucking and rotating by the chucker 35 (see FIG. 23). After that, the excess yarn is cut by the heat cutter 36 (see FIG. 23), and the work is completed.

The 0th stage (0st), the 1st stage (1st), the 2nd stage (2st), and the 3rd stage (3st) described above
As a result, in the package P flowing in the transport path 4, the outermost layer winding 3 is sucked and released, the released yarn end is tied to the outer periphery of the package P, and the bunch winding 1 wound around the paper tube K is released. The released bunch thread end is locked in the slit S of the paper tube K.

These 0th stage (0st) to 3rd stage
As shown in FIG. 1, the (3st) is connected to a control unit 37 that integrally controls each stage. The operation panel 38 of the control unit 37 is provided with an input unit 39 for selectively operating each of the stages. The operation panel 38 is shown in FIG. Panel 3 as shown
The input unit 39 on the 8 comprises a process selection dial for setting four kinds of setting numbers (0 to 3), and the following processes are performed by the number.
