Abstract

PROBLEM TO BE SOLVED: To continuously and efficiently manufacture an bundled electric wire whose respective single wires are not naturally loosened, separated and diffused from a cutting end part by winding them through a center guide plate by collecting three covered conductors passing through a guide hole. SOLUTION: Electric wire bundles A by winding a covered electric wire 4 by covering a metallic conductor 4a of a conductor with an insulating synthetic resin covering 4b, are respectively installed on electric wire bundle holders 3, and its tips are connected to a winding drum 10 through guide holes 5, a center hole 7 and an electric wire sending drum 16. A rotary board 1 is rotated in the constant direction through a driving mechanism 11, that is, a motor 18 and gears 19 and 20. At the same time, the holders 3 are also rotated in the same direction with the rotary board 1 through a driving mechanism 14, that is, a motor 21 and gears 22 and 27. The covered electric wire 4 pulled out of the electric wire bundles A is stranded into a single bundled electric wire 9 by the center hole 7 of a center guide plate 8, and is wound round the winding drum 10. In this case, an electric wire 4 is also twisted into a single bundled electric wire. Its electric wire 9 hardly causes a condition where its end part is naturally loosened, separated and expanded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire twisting machine for twisting three insulated wires to form one collective wire.

[0002]

2. Description of the Related Art Conventionally, there is a type in which three coated electric wires in which a metal core wire of a conductor is coated with an insulating synthetic resin coating are twisted to form a single collective electric wire.

[0003]

Since this collective electric wire is formed by twisting three covered electric wires, when the collective electric wire is pulled out from the take-up reel and cut into a required length during use. , The twisted wire returns from the cut end, and each coated wire naturally separates and diffuses, and its terminal treatment is troublesome and requires extra labor for connection work to terminals and the like.
There was a problem.

Accordingly, the present invention provides a simple wire twisting machine capable of continuously and efficiently producing a twisted collective wire in which each single wire is naturally melted from the cut end and does not separate and diffuse. Its primary purpose is to provide it in a structure.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the wire twisting machine according to the present invention, the horizontal turntable 1 held by the underframe 2 so as to be rotatable about the vertical axis 13,
Three electric wire bundle holders 3 ... Installed on the upper surface of the rotary disc 1 at equal intervals in the circumferential direction, and coaxially integrated with the rotary disc 1 above these electric wire bundle holders. A rotating guide plate 6 having three guide holes 5 for passing the covered electric wires 4 drawn out from the electric wire bundle holder 3 and three covered electric wires 4 passing through the guide holes 4 are gathered in one place. A center guide plate 8 having a center hole 7 that guides upwards, a winding drum 10 that winds up a collective electric wire 9 fed from the center guide plate 8, the turntable 1 and the electric wire bundle holder 3 are the same. The structure is composed of a driving mechanism for rotating the unidirectionally.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on an embodiment shown in the drawings. In the figure, reference numeral 1 denotes a turntable held on an underframe 2 of a casing so as to be rotatable around a vertical axis 13 by a drive mechanism 11. Reference numeral 3 denotes three wire bundle holders 3 arranged on the upper surface of the rotary disk 1 and spaced apart at equal intervals in the circumferential direction, and holds the wire bundle A with the shaft center being vertical. The drive mechanism 14 is formed so as to rotate in the same direction as the turntable.

A rotary guide plate 6 coaxially and integrally connected to the rotary disk 1 via stays 15 is disposed above the wire bundle holders 3. The rotating guide plate 6 has three guide holes 5 through which the covered electric wires 4... Drawn from the electric wire bundles A.
... are provided. Above the rotary guide plate 6, there is provided a center guide plate 8 having a center hole 7 for collecting the three covered electric wires 4 passing through the guide holes 5 in one place and guiding them upward.

Further, there is provided a winding drum 10 for winding the collective wires 9 sent out from the center guide plate 8 via a wire feeding drum 16. The electric wire feeding drum is driven by a motor 17 by an electric wire winding drum 10.
Is rotated by a motor 12.

In the above configuration, the conductor metal core wire 4a
Bundles A each of which is wound with a covered wire 4 coated with an insulating synthetic resin coating 4b, are attached to a wire bundle holder 3, and the ends thereof are guided holes 5, center holes 7, and a wire feed drum 1.
6 to a take-up drum 10. Then, the rotating disk 1 is driven by a driving mechanism 11, that is, a motor 18, a gear 19,
Rotate in a fixed direction through 0. At the same time, the wire bundle holder 3 is also driven by the drive mechanism 14, ie, the motor 21, the gears 22,
7 to rotate in the same direction as the turntable 1.

The covered electric wires 4 drawn from the electric wire bundles A ...
Is wound on a single collective wire 9 in a center hole 7 of a center guide plate 8 and is pulled upward to take up the winding drum 1.
Wound to zero. At this time, since the wire bundles A are rotating in the same direction as the turntable while rotating in the circumferential direction on the turntable 1, the covered wires 4 themselves also reach the center hole 7 in FIG. As shown by a symbol X, the wire is twisted into one collective wire 9 in a twisted state. In this way, it is very unlikely that the end of the collective wire 9 twisted in a state where the individual coated wires are twisted will be spontaneously separated and diffused.

Reference numeral 23 in the drawing denotes a tension adjusting roller for adjusting the tension of the covered wire 4 from the guide hole 5 to the center hole 7, and as shown in detail in FIG. It can be adjusted by moving it up and down at 25.

Further, the center guide plate 8 having the center hole 7 can be moved up and down by loosening the stop screw 26, whereby the covered wire 4 from the guide hole 5 to the center hole 7 can be adjusted. By adjusting the length, the twist pitch (of the collective wire) can be changed.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to these embodiments. For example, in the above embodiment, dedicated motors 18 and 21 are provided for rotating the turntable 1 and the wire bundle holder 3, respectively, to simplify the transmission mechanism, but it is also possible to drive by one motor. In addition, the present invention can be implemented by appropriately modifying it within the scope of providing the constituent elements, achieving the object of the present invention, and achieving the following effects.

[0014]

As described above in detail, according to the present invention, it is possible to continuously and efficiently manufacture a collective electric wire twisted from three covered electric wires, and the individual coated electric wires themselves are twisted. Since each single wire is unwound naturally from the cut end and does not separate and diffuse, it is easy to connect to the target location such as a terminal, and the structure is simple. Therefore, there is an excellent effect that it can be manufactured at low cost.
