(Stopping the winding drum at a fixed position) The motor of the driving device of the winding machine 13 is driven to rotate the empty winding drum 3, and the photoelectric sensor 202 is provided on the collar 4 as shown in FIG. When detecting that the crescent hole 6 has come to the lower position, the rotation of the winding drum 3 is stopped. Then, the winding drum 3 is fixed by a brake so that the position of the crescent hole 6 does not move.

(Movement of Winding Machine) As shown in FIG. 2, the winding machine 13 having the empty winding drum 3 mounted thereon moves to the operating position, and the winding machine 13 at the operating position has completed the winding operation. Move to the terminating position where is empty.

(Preparation for Rope Winding) The wire rod L sent out from the twisting machine is guided by the wire rod guide device 14, and as shown in FIG. 27, the starting end L1 of the wire rod gripper 15 is closer to the winder 13 side. Is grabbed at. Then, as shown in FIG. 28, the carriage 34 on which the wire gripper 15 is mounted retracts toward the upstream side in the wire advancing direction. At this time, since the wire L hangs down, the guider lifter 39 prevents the wire L from sliding on the floor.

Further, as shown in FIG. 29, the trolley 43 on which the winding device 40 and the like are mounted is advanced toward the wire L by the motor 42, and the center of the loop forming device 63 and the starting end L1 of the wire are aligned on a straight line. The starting end L1 of the wire and the hole 100 for inserting the wire of the loop plate 82 face each other.

(Rope winding) As shown in FIGS. 30 and 31, the rope R supplied from the rope supply device 41 passes through the rotary cylinder 80 and is separated from the center of the wire L by the guide rollers 94a and 94b. It contacts the outer surface and reaches the rope gripper 71, and the starting end of the rope R is gripped. At this time, the rope R is at the same horizontal level as the wire L.

As shown in FIG. 32, the rope R is attached to the guide pin 83.
33, the loop arm 81 rotates clockwise about 360 degrees toward the twisting machine as shown in FIG. Then, while pulling out the rope R stocked in the capstan 47 of the rope supply device 41, the rope R is wound around the pins 102a to 102d arranged on the loop plate 82,
Form a loop. At this time, tension is applied to the rope R by the powder clutch 57 of the rope supply device 41.

After the loop is completed, as shown in FIG. 34, the loop plate 82 is rotated by 150 degrees clockwise from the vertical state by the motor 103, and at the same time, the guide pin 83 is raised and the rope R is prevented from coming off the pins 102a to 102d. By adding, twist is added to the loop. Subsequently, as shown in FIG. 35, the moving base 84 is moved by the motor 90 toward the starting end L1 of the wire rod to a predetermined position where the rope R is wound, and the wire rod L is inserted into the hole 100 of the loop plate 82. Then, the loop arm 81 is moved in the opposite direction to the winding direction 9
The rope R is loosened by rotating it by 0 degree and the guide pin 83 is returned to the original position.

When the rope is loosened, the protruding rod 106 is abutted against the wire L so that the rope R can be easily pulled out from the pins 102a to 102d, so that the rope R is wound around the starting end L1 of the wire. After that, the protruding rod 106 is returned to the original position.

In this state, since the diameter of the loop is larger than the diameter of the wire rod L, the loop L comes out of the wire rod L. Therefore, the flyer 48 rotates in the direction to rewind the rope R, pulls and tightens the rope R, and the rope R becomes It is wound around the wire L. When the first rope winding is completed, the movable table 84 returns to its original position, and the loop forming and winding operations are repeated again, and the rope R is wound around the starting end L1 of the wire rod a required number of times. The stop position of the moving table 84 at the time of winding each time,
Each of them is set as shown in FIG. 36, and the first winding is set so that the loop is at the first position of the starting end L1 of the wire and is at the second position, the third position, and the fourth position after the second winding. .

(Induction of Rope) After winding the rope R,
As shown in FIG. 37, the carriage 43 returns from the wire L to the original position, and as shown in FIG. 38, the carriage 34 moves to the take-up drum 3 side and the guide of the rope R to the take-up drum 3 is started. .

First, the vertical bar 118 of the rope guide portion 117 attached to the carriage 34 moves forward, and the rope R is extended to the winder side.

Next, the first pull-out portion 114 is lowered from the standby position, and as shown in FIGS. 39 and 40, the first pull-out roller 121 moves toward the rope guide portion 117 in parallel with the wire rod advancing direction and is further wound up. It moves in the axial direction of the winding drum 3 toward the inside of the collar 4 of the drum 3, and stops when it comes between the two vertical bars 118 arranged side by side. Then, the first pull-out roller 12
1 is lowered to the height of the rope R, and the rope R is held by the rope retainer 124 and the rope R is caught by the first pull-out roller 121. Further, the first pull-out roller 121 is moved to the vicinity of the winding drum 3, and the rope R is pulled out. At this time, the rope R is paid out by the flyer 48 without being loosened while being tensioned.

(Rope pull-in) When the rope R is pulled out to the vicinity of the winding drum 3, the lifter 142 rises, and two second pull-out rollers 140 mounted on the upper surface of the lifter 142 are lined up as shown in FIG. First pull-out roller 121
In between, it rises to the same height as the rope R and stops.

Then, as shown in FIG. 42, the second drawing roller 1
40 starts pulling out the rope R from the midpoint of the two first pull-out rollers 121, moves to the take-up drum side with the rope R hooked, and the rope R makes contact with the body of the take-up drum 3 and the collar 4 It is guided over the crescent hole 6 to the point where it passes about 250 mm from the center of the winding drum 3.

At this time, the wire L is positioned away from the winding drum 3, but when the wire L is fed out, the tension of the rope R alone causes the wire L to loosen downward due to the weight of the wire L itself. . Therefore, it is necessary to support the wire rod L by the rollers 135 and 136 of the wire rod receiver 116 so as not to loosen the wire rod L.

Therefore, as shown in FIG. 43, the wire rod receiver 116 above the wire rod L in front of the winding drum 3 is moved to the wire rod side to a position outside the collar 4 of the winding drum 3,
Next, it is moved to the outside of the collar 4 and lowered, and is moved toward the inside of the collar 4. The wire rod receiver 116 moves to below the wire rod L, and the wire rod L is supported by the rollers 135 and 136.

(Advance of wire rod) When the twisting machine is operated and the rope R is rewound by the flyer 48, the wire rod L moves toward the winding drum 3 while slidingly contacting the rollers 135 and 136. Then, as shown in FIG. 44, the starting end L1 of the wire is in front of the crescent hole 6 (about 900 m from the center of the winding drum 3).
When it comes to m), the operation of the twisting machine is stopped and the progress of the wire L is stopped.

(Rope pull-out) Next, as shown in FIG. 45, the rope hook 150 moves forward in the direction of the winding drum 3 and passes through the crescent hole 6 from the outside of the collar 4 of the winding drum 3 to pull the rope R. And pulls the rope R out of the collar 4 by retracting the rope hook 150.

(Cut of rope) At this time, the rope R is
As shown in FIG. 46, it is pulled out to the outside of the collar 4 and bent into a V shape, and after the portion of the rope R from the starting end L1 to the outside of the collar 4 is grasped by the rope grasping device 160, an excess is obtained. The rope R is cut by the rope cutting machine 161. At the same time as the cutting, the cut excess rope R is tensioned by the powder clutch 57, so the flyer 48 is rotated and rewound, and the rope R is wound around the capstan 47.

(Stopping the winding drum at a fixed position) The motor of the drive unit of the winding machine 13 is driven to rotate the empty winding drum 3, and the crescent hole 6 provided on the collar 4 by the photoelectric sensor 203 causes the wire rod L to move. When it is detected that the position reaches the end of, the rotation of the winding drum 3 is stopped. Then, the winding drum 3 is fixed by a brake so that the position of the crescent hole 6 does not move.

(Fixing of Rope) While the rope gripping device is moved in the outer peripheral direction of the collar 4, the twisting machine performs the inching operation to feed the wire rod L, and the starting end L1 of the wire rod is moved to the rope R as shown in FIG. When it is guided and enters the crescent hole 6 and the outer surface of the collar 4 is fully inserted, the movement of the rope gripping device 160 is stopped and the operation of the twisting machine is stopped.

At this time, the rope R wound around the starting end L1 of the wire is in a state of being in close proximity along the outer surface of the collar 4, and the rope R is guided by the rope guide member 196.
Then, as shown in FIG. 48, the extra length of rope is nailed to the outer surface of the collar 4 by the nailing machine 190 as shown in FIG.

The number of nailing operations is appropriately set according to the type of wire L and the type of winding drum 3. In this way, by fixing the rope R to the collar 4, the starting end L1 of the wire is automatically fixed to the winding drum 3, and the work efficiency is improved without requiring human labor. (Winding operation) When the start processing of the wire L is completed, each device automatically returns to the original position and enters the standby state. And
The operation of the winding machine 13 and the twisting machine is started, and the wire L is wound around the winding drum 3. At this time, since the starting end L1 of the wire rod is at the end of the winding drum 3, when the wire rod L is reciprocally moved in the axial direction by the traverse mechanism and is wound up, the wire rods L are aligned and wound as shown in FIG.

(Stopping of the winding operation) The length of the wire L is measured by the measuring scale wheel during winding, and when the length of the wire L is wound by the set length on the winding drum 3, the winding machine 13 and the twisting unit are twisted. The machine stops, and the termination process of the wire L is started.

(Cutting of Wire Rod) As shown in FIG. 50, two portions before and after the cut portion of the wire rod L are arranged so that the twisted wire rod L does not come apart.
Vinyl tape is wrapped around the place. Then, the winding machine 13 and the twisting machine are inching-operated, and fed out until the tape winding portion reaches the cutting position. At this time, the lifter 39 with the guide roller is raised to match the heights of the wire gripper 15 and the wire L.

The upstream side of the tape winding portion of the wire L is gripped by the wire gripper 15 and at the same time the downstream side is gripped by the terminal gripper 35. The wire rod cutting device 36 moves to the middle of the gripped portion of the wire rod L, and as shown in FIG.
The wire L is cut between the tapes wound in two places.
At this time, the cut end on the twisting machine side becomes the starting end L1 of the wire,
The cut end on the winding drum 3 side becomes the terminal end L2 of the wire.

(Movement of Winding Machine) The winding machine 13 equipped with the winding drum 3 with full winding moves from the operating position to the vacant end processing position A or B, as shown in FIG.
At the same time, the winder 13 equipped with the empty wind-up drum 3 moves to the operating position.

(Rope winding) When the end side rope winding means 10 is moved in the axial direction and the end L2 of the wire rod is detected by a photoelectric sensor or the like, the movement is stopped and the wire rod holder 180 is stopped.
Is opposed to the end L2 of the wire, the end L2 of the wire is gripped, and the end gripper 35 is opened. Then, as shown in FIG. 52, the rope R is wound around the terminal end L2 of the wire by the terminal end side rope winding means 10 in the same manner as the starting end processing.

(Induction of the end of the wire) After the winding of the rope around the end L2 of the wire is completed, the winder 13 is operated and the flyer 48 is rotated to apply a constant tension to the rope R by the powder clutch 57. The wire L is wound on the winding drum 3 again. And control the traverse mechanism,
As shown in FIG. 53, while winding the wire L and the rope R around the winding drum 3, the rope R is guided to the collar 4 on the side of the kelly 16 and the winding machine 13 is stopped.

(Rope Positioning) The rope R is close to a position close to the inner surface of the collar 4, and the rope position correcting device 187 is raised to move the rope R by the rope position correcting device 187 as shown in FIG. Move and position so that it touches.

(Rope fixing) As shown in FIG.
As described above, nailing is performed by the nailing machine 190 to fix the rope R to the inner surface of the collar 4. Each time the nail N is hit, the winding drum 3 is rotated, and the nail is nailed a predetermined number of times depending on the diameter of the wire L. After the driving, the rope R is cut between the winding drum 3 and the rope gripping device 184 by the rope cutting machine 18
Cut by 6.

The extra rope R is rewound by the flyer 48, and each device automatically returns to its original position, and the termination process is completed.

(Replacement of Winding Drum) The pintle on which the winding drum 3 is supported is lowered by driving a motor or the like, and the other pintle is moved to the outside to pull out the pintle from the winding drum 3 to wind the full winding. The take-up drum 3 is taken out from the winder 13. Then, the empty winding drum 3 is set.

Thus, the starting end L1 and the ending end L of the wire rod are
