Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a twisting machine, and more particularly to an improvement of a vertical twisting machine with a twist back which can be constructed in a small size.

[0002]

[Prior art]

 The vertical type twisting and twisting machine is relatively widely used because it can be constructed compactly, is inexpensive, and can produce high-quality twisted wires. Thus, the conventional vertical twisting and twisting machine is constructed as shown in FIG. That is, the vertical twisting and twisting machine 1 includes a twisted wire portion 3 attached to a lower portion of a frame 2, a twisted wire portion 4 attached to an upper portion of the frame 2, and the twisted wire portion 3. It has a connecting portion 5 for mechanically interlocking with the twisting portion 4.

In the conventional twisting machine 1 with the above-described twist-back, the wire 6 wound around the bobbins 6 a, 6 b is introduced into the twist-back section 4 from above the twist-back section 4, While being twisted by the twisting portion 4 which is interlocked with the portion 3 and the connecting portion 5, it is fed into the twisted wire portion 3 via the guide sheaves 7, 7. The twisted wire portion 3 is provided with a rotary rack 9 supporting a bobbin 8 around which the twisted twisted wire is wound. The rotary rack 9 has guide sheaves 11 and 12 for guiding the twisted twisted wire 10. The turn sheave 13 and the traverse sheave 14 for reciprocating the stranded wire 10 in the axial direction of the bobbin 8 are provided respectively.

The wires 6 are twisted together by the rotation of the rotary frame 9 and become a twisted wire 10 which is guided to the bobbin 8 via the guide sheave 11, the turn sheave 13, the guide sheave 12, and the traverse sheave 14, and then to the bobbin 8. It is designed to be wrapped around.

Incidentally, Reference numeral 15 in FIG. 6 is a wire breakage detector, which generates a stop signal for the twisting machine when the wire breakage occurs.

[0006]

[Problems to be solved by the device]

 When winding a large number of insulating strands, mainly a litz wire made by twisting a large number of enamel strands, into a coil as is, wind the coil around the coil with a uniform configuration in the circumferential direction. At this time, it is desired that no deformation occurs, but it is not possible to obtain a litz wire having a uniform configuration in the circumferential direction as described above with the current general double twist buncher.

The litz wire having the above characteristics can be manufactured by a single twist stranded wire machine. Thus, the twisted wire portion 3 of the twisted wire machine 1 with the above-described twist-back can be used as a single twisted wire twister only in this portion. However, the twisting part 4 and the connecting part 5 of the twisting and twisting machine 1 become obstacles during the mounting of the wire and the workability is extremely poor, and the litz wire is manufactured using the twisting and twisting machine 1 That is not practical.

The present invention has been made based on the above circumstances, and provides a twisting machine with a twisting back, which can efficiently produce, for example, a litz wire or the like as a single twist twisting machine by using only a twisted wire portion. To do.

[0009]

[Means for Solving the Problems]

 The twisting machine with twisting back of the present invention is characterized in that the twisting section and the twisting section are mechanically configured independently of each other, and both of them can be electrically driven synchronously as needed.

[0010]

[Action]

 In the twisting machine with twisting back of the present invention having the above-mentioned structure, when manufacturing a litz wire or the like by using only the twisting section, there is no connecting section which hinders the insertion of the strand, and the twisting section Since it can also be placed in a place that does not hinder the insertion of the strands, the above manufacturing work can be performed efficiently.

[0011]

【Example】

 FIG. 1 is a front view of an embodiment of the present invention. In FIG. 1, a twisted wire portion 23 having substantially the same configuration as the twisted wire portion 3 and a twisted portion 24 having substantially the same configuration as the twisted portion 4 in the conventional twisting machine 1 shown in FIG. An electric motor 28 for driving the twisted wire portion 23 and an electric motor 29 for driving the twisted wire portion 24 are made independent of each other by 26 and 27, and are made synchronous or asynchronous by a synchronous circuit 30 as desired. .

In the embodiment of the present invention having the above-described structure, as shown in FIG. 3, the supply reels 31 and 31 are attached to the twisted-back portion 24, and the supply reels 31 and 31 are wound around the supply reels 31 and 31. The wire 32 is supplied to the twisted wire portion 23 via a guide sheave 33 above the twisted-back portion 24 and a guide sheave 34 above the twisted wire portion 23, and is twisted in the twisted wire portion 23 to form a twisted wire (not shown). However, the fact that the twisting portion 24 does not twist the strands is the same as in a general twisting and twisting machine.

Reference numeral 35 in the figure denotes a signal line for transmitting an electrical synchronization signal of both the parts.

In the embodiment of the present invention, not only is it used as a twisting and twisting machine as described above, but also the twisting back section 24 is stopped and only the twisting wire section 23 is actuated. It can also be used as a wire machine. Thus, in the present invention, the twisted wire portion 23 and the twisted-back portion 24 are electrically synchronized and independent, if necessary, and no mechanical connecting means is provided between them. Therefore, if only the twisted wire portion 23 is used as shown in FIG. 2 and a single twisted wire twisting machine is used, as in the conventional twisted wire machine with twisting back shown in FIG. And the like do not hinder the insertion of the strands, and the Litz wire or the like can be efficiently produced. Furthermore, when the number of strands to be twisted together is large, the strands 32 can be supplied from four sides as shown in FIG.

The present invention is not limited to the above embodiment. For example, as shown in FIG. 5, the present invention can be applied to the case where the twisted-back portion 24 is directed downward and the twisted wire portion 23 is supplied from above the twisted wire portion 23. There is.

[0016]

[Effect of device]

 As is apparent from the above, in the twisting machine with twisting back of the present invention, the twisting section and the twisting section have an independent structure in which they are electrically operated in synchronism if necessary. Since there is no connecting part that mechanically connects the twisted wire part and the twisted part of the machine, the above-mentioned connection part or twisted part does not hinder the insertion of the strand when using only the twisted wire part. The litz wire and the like can be efficiently manufactured.
