Abstract

PURPOSE:To form a plurality of alternately stranded layers by tuning each pair of winders and receivers having the rotating directions differed every stranded layer with a feeder for feeding stranded wires and rotating them alternately. CONSTITUTION:A plurality of pair stranded cores 5 delivered from a pair stranding type feeder 4 are collected by a die 6, a winder 1 and a receiver 2 are rotated to the left to conduct left-handed stranding, and the resulting cable is wound on the take-up rotating type winder 1 after a tape is wound thereon by a taping machine 3. After stranding of a determined length is finished, the stranded cable is pulled out from the winder 1 by the winder 1, the plurality of pair stranded cores 5 delivered thereon from the feeder 4 are collected by a die 6', a winder 1' and a receiver 2' are rotated to the right to form a right-handed stranded layer, on which a tape is wound by a taping machine 34, and the stranded cable is wound on a take-up rotating type winder 1'. Hence, the winders 1, 1' and the receivers 2, 2' are alternately rotated in such a manner as to be tuned with the feeder 4, whereby a plurality of alternately stranded layers can be formed at high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a twisting machine used for manufacturing communication cables and the like.

[Prior Art] When making communication cables by twisting paired or cut stranded wires using a twisting machine, conventionally, a cage-type twisting machine is used, and the cage is rotated in forward and reverse directions, or the winding is performed using a winding rotation type winding method. Using a removing machine,
- So-called alternate twisting of each layer was performed, in which the direction of twisting was reversed for each layer and the direction of twisting was reversed for each layer.

[Problems to be Solved by the Invention] In the conventional winding rotary type winding machine, the winding machine and the take-up machine are rotated forward and backward for each layer, resulting in poor operational efficiency.

On the other hand, a cage-type wire twisting machine cannot rotate at high speeds because it rotates a plurality of bobbins to which paired or cut twisted wires are attached.

In addition, since pair twisting and cut twisting must be performed for all the twists, it takes a lot of time for setup, resulting in poor operating efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a twisting machine that eliminates the drawbacks of the prior art and can perform alternate twisting of each layer with high efficiency when manufacturing communication cables and the like.

[Means for Solving the Problems] In the present invention, a pair of left and right winding machines and a take-up machine having mutually different rotation directions are provided, and a sending machine supplies pairs or cuts of twisted wire for each twisted layer. The winding machine and the take-up machine are alternately rotated in synchronization with the above to form a plurality of alternately twisted layers.

[Operations] In the present invention, a pair of winders rotate in different directions for each twisted layer, and the take-up machine rotates alternately in synchronization with the sending machine that supplies the twisted wire, so that the conventional cage type Alternate twisting of the twisted layers can be performed simultaneously with paired twisting at high speed without using a cage such as a twisting machine, and efficiency can be improved.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of a twisting machine showing this embodiment. In the figure, 1.1- is a winding machine, 2.2- is a take-up machine, 3.3 is a taping machine, 4 is a sending machine, 5 is a twisted core. 6. 6' is a die.

The operation of the above configuration will be explained below.

The plurality of twisted pair cores 5 fed out from the twisted pair type sending machine 4 are collected by a die 6, the winding machine 1 and the take-up machine 2 are rotated to the left to perform left-handed twisting, and the taping machine 3 The tape is wound and taken up by a take-up rotary type winder 1.

After completing the twisting of a predetermined length, the twisted cable is then pulled out from the winder 1 by the winder 1', and the real number of twisted pair cores 5 fed out from the feeder 4 are placed on top of the twisted cable. Dice 6
′, the winding machine 1 take-up machine 2- is rotated in the clockwise direction to form a right-handed twisted layer, and the tape is wound with the taping machine 3', and then the tape is assembled on the winding rotary winding machine 1'. Wind it up.

In this way, the winding machines 1, 1'' and the take-up machines 2, 2 are alternately rotated in opposite directions in synchronization with the sending machine 4, so that left-handed twisting and right-handed twisting are alternately repeated. A sending machine that supplies twisted wire in pairs or cuts has a function of twisting or cutting.

Thus, according to this embodiment, the alternate twisting of the twisted layers can be performed at high speed at the same time as the pair twisting without using a cage like the conventional cage type twisting machine, and efficiency can be improved.

[Effects of the Invention] According to the present invention, it is possible to obtain a twisting machine that eliminates the drawbacks of the prior art and can perform alternate twisting of each wire with high efficiency when manufacturing communication cables and the like.
