The yarn F stretched between the yarn holder 45 and the yarn holder 45 is cut by the cutter 54 as shown in FIG. 7 (D), and the yarn guide 44 and the yarn holder are provided near the yarn end on the entry side of the cut yarn F. It is held in a state of being gripped by 45.

In this state, the full spool 10B is the full spool 10B described above.
Is taken out from the winding section 3 and conveyed to the full spool storage section 2 in accordance with the relay transfer operation of the full spool 10B.
After unloading, the empty spool 10A moves from the empty spool storage unit 1 to the winding unit 3 in accordance with the above-described relay transfer operation of the empty spool 10A.
And is set on the take-up spindle 24.

Then, the empty spool 10A is reset on the take-up spindle 24, the main motor M1 and the second geared motor GM2 are stopped, and the starting end of the yarn F is grasped by the yarn guide 44 and the yarn holder 45 at the yarn cutting position ( As shown in FIG. 8 (A), when the operation start signal is transmitted, the first geared motor GM is controlled so that the winding spindle 24 makes about two rotations.
1 is rotationally driven and then stopped, and the yarn guide 44 and the yarn holder 45 hold the yarn end as shown in FIGS. 8 (B) and 8 (C), and rotate about 2 turns around the empty spool 10A from the standby position. Then, it stops at the standby position again, the starting end of the yarn F rotates twice around the empty spool 10A together with the winding spindle 24, and the vicinity of the lower end of the yarn is wound around the empty spool 10A twice. When the first geared motor GM1 is stopped and the winding operation of the yarn F is completed, the main motor M1 and the second geared motor GM2 are activated to resume the regular yarn winding operation. When the main motor M1 is activated, the first solenoid S1 operates to release the starting end of the yarn F.

Next, the operation and effect of the embodiment having the above configuration will be described.

A disk-shaped spool 10 having a center hole 10a is replaced with an empty spool 1
An empty spool storage unit 1 for storing in the state of 0A, and a full spool installed adjacent to this empty spool storage unit 1
Full spool storage section 2 for storing 10B and thread F
Winding section 3 provided with a take-up spindle 24 that is driven to rotate in order to wind up a spool, and empty spool 10A is relayed from empty spool storage section 1 to winding section 3 and full spool 10B is taken up. A relay transport mechanism 4 for relay-transporting from the section 3 to the full spool storage section 2 is provided, and a plurality of empty spools 10A are stacked in each of the empty spool storage section 1 and the full spool storage section 2. Multiple sets of empty spool groups, or multiple full spools 10B each
A plurality of sets of full-filled spool groups, each of which is stacked, are stored in a planetary arrangement, and storage disks 12 and 18 are provided, and a rotation drive mechanism that intermittently rotates the storage disks 12 and 18, respectively. 4 has a function to carry out the empty spool 10A from the storage disk 12 and a full spool 10
A spool loading / unloading means having a function of loading B onto the storage disk 18, and an empty spool storage unit 1
Side to the winding section 3 side, and the function of changing the attitude of the empty spool 10A from the horizontal attitude to the upright attitude, and transferring the full spool 10B from the winding section 3 side to the full spool storing section 2 side. In addition, it has a function of changing the attitude of the full spool 10B from an upright attitude to a horizontal attitude, and a spool movement changing means for carrying the empty spool 10A and the full spool 10B by passing through substantially the same carrying path. A spool setting mechanism for setting the empty spool 10A on the winding spindle 24 is provided in the winding section 3, a yarn winding mechanism for winding the yarn on the empty spool 10A prior to the start of winding, and a yarn winding mechanism. A thread cutting mechanism for cutting F is provided.

Therefore, the empty spool 10A is conveyed from the empty spool storage unit 1 to the winding unit 3, set on the winding spindle 24, the yarn F is wound on the set empty spool 10A, and the full spool 10B is wound. A series of operations for taking out from the part 3 and carrying it to the full spool storage part 2 can be properly and smoothly carried out, and there is an effect that the yarn winding process is fully automated and unmanned continuous operation is possible. .

Further, since the empty spool 10A and the full spool 10B are transported by the relay transport mechanism 4 through almost the same transport path, the space required for installing the relay transport mechanism 4 can be simplified by simplifying the relay transport mechanism 4. Can be reduced.

Furthermore, in the empty spool storage unit 2, a plurality of empty spools 10
A plurality of sets of empty spool groups in which A is stacked are arranged in a planetary shape to store the empty spool 10A in a state suitable for the shape of the spool, and in the full spool storage unit 2, a plurality of full spools 10B are stacked. Since a plurality of sets of full-filled spool groups are arranged in a planetary shape and the full-filled spool is stored in a state suitable for the shape of the spool, it is necessary to install the empty spool storage unit 1 and the full-filled spool storage unit 2. Space can be reduced.

Also, when starting winding the yarn, start the yarn end with an empty spool.
After winding a suitable number of times for 10A with the thread winding mechanism,
Since the winding of the yarn is started, the operation of winding the yarn on the empty spool can be started properly and stably.
