Are held at an interval (play and constitutes a dead zone), and the distal end of the arm 67 is connected to prevent the hanging wire A from detaching from the contact 66.

In the slack section 3 of the suspended hanging wire A, twisting occurs between the hanging wire A pulled up to the wire ironing section 5 and the hanging wire A fed from the wire feeding section 4. If present, it will buckle in the sagging sag section 3 and the hanging wire A will be displaced from the wire winding surface P, which will cause the contact 66 to pivot. , The shift direction and the shift amount are detected by the potentiometer 64.

The controller 10 is provided with the detecting means 9
From the potentiometer 64 to monitor the shift direction and the shift amount due to the twisting of the suspended hanging wire A in the slack section 3, and apply a twist in the opposite direction to the shifting direction to the hanging wire A. The turning table 24 and the supply drum 2 are turned. This turning angle depends on the hanging wire A
Is adjusted in accordance with the shift amount of.

The wire straightening section 6 is arranged on the other carriage 16, and a plurality of straightening rollers 70 are arranged in the direction in which the hanging wire A is fed, and repeatedly bent into the hanging wire A sent from the wire ironing section 5. The suspension wire A is linearized by giving a deformation, and therefore, the contact direction of each correction roller 70 with the suspension wire A is set to the opposite side in the adjacent correction roller 70.

The straightening rollers 70 are arranged at the tip of a rod 71 that penetrates the hanging drum driving section 8,
The fixed position of the rod 71 can be adjusted and changed.

The hanging drum driving section 8 has a spindle 72 for rotatingly driving the hanging drum 7 which is detachably attached to the tip. The spindle 72 corresponds to the wire diameter of the hanging wire A with the rotation. The hanging wire A wound around the hanging drum 7 is arranged so as to be movable in the axial direction, and is wound in a line.

Reference numeral 73 denotes a display device which obtains a detection signal from the detecting means and a control amount for a motor for turning the turning table from a controller, and displays them.

The supply drum 2 is wound and supplied at the manufacturing site of the suspension wire A, and a plurality of suspension drums 7 are provided.
A hanging wire A of sufficient length that can be wound
Since the supply drum 2 is freely rotatable as it is wound as a long wire, the suspension wire A can be pulled out when the suspension wire A is wound around the suspension drum 7.

First, the drawing of the hanging drum 7 attached to the spindle 72 via the wire feeding section 4, the slack section 3, the wire squeezing section 5, and the wire straightening section 6 with the drawn hanging wire A is shown. Engage with the end fixing part not to be used.

Next, the tension roller 60 is rotated by the tension motor 58 to apply a predetermined tension to the suspension wire A between the wire ironing section 5 and the suspension drum 7, and the spindle 72, each feed motor 39, The hanging wire A is wound from the supply drum 2 to the hanging drum 7 by rotating the spindle 72 at a predetermined pitch in the axial direction corresponding to the winding. Is wound up by the alignment winding.

When the hanging wire A hung from the wire feeding portion 4 in the slack accommodating portion 3A contains a twist, the hung hanging wire A is twisted and deviated from the wire winding surface P. For the shift, the arm 67 of the contact 66 is turned, and the shift direction and the shift amount are detected by the potentiometer 64 via the turning shaft 65.

The controller 10 includes a potentiometer 6
According to the shift direction and the shift amount of the suspension wire A from 4,
Calculate the twist direction and twist amount of the suspension wire A,
A direction in which the drive motor 28 of the swivel table 24 is driven to rotate the swivel table 24 in accordance with the torsion direction and the amount of torsion of the suspending wire A, and the suspending wire A supplied from the supply drum 2 cancels the torsion amount. And supply it in the opposite direction by the amount to cancel.

When the hanging wire A twisted in the opposite direction is hung down in the slack section 3, the twisting is eliminated at once, and the hung hanging wire A returns to the wire winding surface P, and the potentiometer 64 is turned off. The deviation amount signal from the controller to the controller 10 disappears, and the controller 10
8 is stopped, and the swivel angles of the swivel table 24 and the supply drum 2 are maintained at a new payout angle at which the shift amount signal to the controller 10 has disappeared.

That is, each time the suspension wire A is twisted, the swing angle of the swing table 24 and the supply drum 2 is turned in the direction of returning the twist by the amount of twist, and the twist is increased by the total amount of twist. In the direction to return the wire A, and as a result, the twist of the suspension wire A is eliminated.

By repeating the above operation every time when the twisting of the hanging wire A is detected, the hanging wire A can be wound around the hanging drum 7 without twisting.

The above-described embodiment has the following effects.

That is, the shift direction and the shift amount from the neutral position in the horizontal position through which the hanging wire A suspended in the slack section 3 passes are detected, and the swing is made according to the shift direction and the shift amount. In order to return the passing position of the hanging wire A suspended in the slack section 3 to the neutral position by rotating the rotating table as a means, the supply drum 2 is turned to return the torsion every time the hanging wire A is twisted. Is turned and the torsion is not accumulated in the suspension wire 7, and the suspension wire 7 can be wound around the suspension drum 7 in a state where the torsion is surely eliminated.

Further, since the passage hole of the detecting means 9 is formed longer by the arm 67 in the radial direction of the detector 66, it is possible to detect only the deflection in the direction caused by the twist of the suspension wire A in the slack section 3, and Twist detection can be reliably performed.

Furthermore, since the hanging wire A is repeatedly and repeatedly bent by the wire straightening unit 6 to be linearized and then wound around the hanging drum 7, it can be wound around the hanging drum 7 without meandering. .

Moreover, since the hanging drum 7 is wound while being moved in the axial direction by the diameter of the hanging wire A per rotation, the hanging drum 7 can be wound in alignment with the hanging drum 7.

Further, since the wire feeding roller 38 and the pulling roller 47 to the slack section 3 guide the hanging wire A in the vertical direction, the trajectory of the hanging wire A can be stabilized, and the twist detection accuracy can be improved. The twist can be surely eliminated.
