Description

TECHNICAL FIELD The present invention relates to a core wire twisting machine for twisting core wires together with inclusions.

[Conventional technology and its problems]

When twisting the insulating core wire, inclusions such as jute and paper are fed out and twisted together with the insulating core wire in order to fill the valley formed by the twisting.

Ideally, the inclusions should be as soft and soft as possible, which results in a good product and saves the amount of intervening material used.

In particular, the paper interposer is usually a tape-shaped material that is softly rolled into a tubular shape in the process of feeding it and converges into a die through the eye plate. Due to the pressure, the tubular shape is left behind and cannot be softly rolled.
When twisted in such a state, the twisted core does not have a round finish.

From the above circumstances, while the paper intermediary is fed out and converged in the die, it is almost in a free state, and means for controlling individual tensions are not provided, Therefore, there was a problem that the finished outer diameter was uneven.

[Object of the Invention]

In view of the above problems, the present invention provides a core wire twist that applies constant tension to the inclusions without applying special pressure until the inclusions from which the insulating core wire is fed out are converged in the die. The purpose is to provide a matching machine.

[Means for achieving the purpose]

In order to achieve the above object, in the present invention, a means for feeding out the core wire while giving twist to the core wire to be twisted,
A means for feeding a tape-like inclusion that fills the gap between the twisted core wires and the core wire into a tubular shape, and a means for converging the drawn-out core wire and the inclusions into a die through the eye plate, In a conventionally known core wire twisting machine consisting of a wound and converged core wire and a winding and twisting means for twisting the inclusions, a surface is slid on the inclusions until it is fed out and converged in a die. A roller serving as a stop surface is disposed in contact with the roller, and a slip coupling is interposed between the roller and the roller shaft.

[Action]

In the core wire twisting machine according to the present invention configured as described above, the core wire and inclusions are fed out, converged and twisted by a die and wound as in the conventional case.

At this time, as the inclusions are fed out, the rollers on the anti-slip surface are rotated, and a predetermined braking force is applied to this rotation by the slip coupling. Therefore, by appropriately setting the braking force, an appropriate tension is applied to the inclusion while maintaining the tubular shape, and the tubular inclusion is smoothly intervened in the void of the core wire.

〔Example〕

FIG. 1 is an overall layout view of a core wire twisting machine according to the present invention, in which an insulating core wire 1 is guided along a group roller 3 while being twisted from a twisting supply 2 and passes through an eye plate 4. (A plurality of eye plates may be provided at intervals if necessary.) Converged in the twisting die 5.

On the other hand, the paper intervening a filling the gap between the core wires 1 after twisting is
As shown in FIG. 3, the paper tape pad 6 is fed from the core of the paper tape pad 6, passes through the guide roller 7, passes through the eye plate 4, and is converged by the twisting die 5, and at the same time as the rotary winder 9 and this. By the rotation of the rotating rotary take-up machine 14, the insulated core wire 1 is twisted together with the converged insulating core wire 1.

The insulated core wire 1 is twisted to form a twisted core 11, which is taped directly above by a taping machine 6'and then taken up by a rotary take-up machine 14 and mounted on a rotary winder 9.
Winded up to 10.

Reference numeral 12 is a twisting core swing stop, 13 is a guide roller, 8 is a traverse mechanism, and B is a bearing.

FIG. 2 is a perspective view of an essential part of the present invention, in which gold sand 71 is attached to the surface of the guide roller 7 with an adhesive.
A blade 72 is attached to one end of the to rotate with it.

A sensor 73 for detecting the movement of the blade 72 is attached at a position opposite to the blade 72, and a slip coupling 75 is provided between the roller 7 and its shaft 74.

With the above-described configuration, the paper intervening a reliably rotates the roller 7 on the anti-slip surface as the paper interposing a is fed out, but the slip coupling 75 exerts a predetermined braking force on this rotation. Therefore, by appropriately setting the braking force, an appropriate tension is applied to the paper intervening a while maintaining the tubular shape, and the tubular paper interposing a smoothly intervenes in the void of the core wire 1. To be done.

Further, as the roller 7 rotates, the blade 72 co-rotates, and it is detected whether or not the paper intervening a is normally drawn out by the presence or absence of the rotation of the blade 72. An alarm or a machine is stopped by the detection signal by the.

In the above-mentioned embodiment, a hard sand 71 is formed on the surface of the roller 7 to prevent slipping.
However, a wire brush roller can be used. In addition, although the roller 7 has a cylindrical shape,
As shown in the figure, if it is formed in a continuous shape, the crush preventing effect of the paper interposition a is further improved.

〔The invention's effect〕

The present invention is configured as described above, and the frictional contact ensures that the roller can be rotated as the inclusions are paid out, and a braking force is applied to the rotation by the slip coupling, so that the interpositions taken out. Since a certain tension is applied to the object, the inclusion can be softly rounded without being crushed and twisted together with the core wire to smoothly obtain a twisted core having a uniform outer shape.
