本発明は、導線入りプラスチックチューブの製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a method of manufacturing a plastic tube containing a conducting wire.
(発明の技術的背景)
第5図は導線入りプラスチックチューブの断面を示し、
該チューブの内周面側には複数の導線lが埋設されてい

組込まれて可燃性高圧ガス等の送給管として利用され、
又導線1は圧電素子等の接続端子に接続される。(Technical Background of the Invention) Figure 5 shows a cross section of a plastic tube containing a conducting wire.
A plurality of conducting wires 1 are embedded in the inner peripheral surface of the tube. A plastic tube with such a structure is incorporated into an ignition device and used as a delivery pipe for flammable high-pressure gas, etc.
Further, the conducting wire 1 is connected to a connection terminal of a piezoelectric element or the like.

により各導線を一定張力にて押出成形機に導入するよう
にしている。Now, such a plastic tube is manufactured as follows. That is, the conductive wires are fed out from a plurality of supply bobbins wound with conductive wires and introduced into an extrusion molding machine, and each conductive wire is embedded in the extrusion molding machine and extruded into a plastic tube. Conventionally, when the conductive wires are fed out, tension is applied to each conductive wire using a tension regulator, so that each conductive wire is introduced into the extrusion molding machine with a constant tension.

ューブの生産性が低下してしまう。(Problems with the Background Art) However, since the tension regulator cannot apply completely the same tension to each conducting wire, a large tension is applied to one of the conducting wires, which often causes the wire to break. Although it is possible to reduce the rate at which the conducting wire is introduced into the extrusion molding machine to reduce breakage of the conducting wire, in this case, the productivity of the plastic tube containing the conducting wire is reduced.

撚り合わされている。FIG. 3 shows the configuration of a device for twisting the conducting wires 1, and in the figure, 2 is a well-known wire winder. A plurality of (four) conductive wires 1 are supplied to this combined wire winder 2, and each conductive wire 1 is fed out from a supply pobin 3 via a fryer 4. Therefore, a plurality of conductive wires 1 are twisted together and wound around the winding pobbin 5 attached to the wire winder 2. FIGS. 4(A) and 4(B) show the conductive wires 1 twisted together by the wire winder 2, and the four conductive wires 1 are twisted at a constant pitch.

る。In the manufacturing method of the present invention, the twisted conductive wires 1 are
As shown in the figure, the fiber is introduced into an extrusion molding machine 9 while removing its twist. That is, the winding pobbin 5 on which the twisted conductive wire 1 is wound is rotatably supported by the shaft 5a thereof on the opening-shaped support 6. The support body 6 is attached to a turntable 7, and the turntable 7 is rotationally driven by a drive mechanism (not shown). Therefore, the winding pobbin 5 rotates on its own axis with the rotation of the turntable 7 and unwinds the twisted conductive wire 1. On the other hand, the drawn-out conducting wire 1 is passed through a separator (batten) 8 and introduced into an extrusion molding machine 9. Therefore, the twisted conductive wires 1 are untwisted immediately before being passed through the separator 8, and introduced into the extrusion molding machine 9 at a fixed position.

。尚、導線1を予め過熱しておくのが好ましい。FIG. 2 shows a sectional view of the extrusion molding machine 9, in which the hollow tube 16 is guided into the center hole 4a of the nipple 4, its tip is inserted into the center hole 14 formed in the guide portion 12 of the nipple 4, and its proximal end is inserted into the center hole 14 formed in the guide portion 12 of the nipple 4. is connected to an inert gas source (not shown). On the other hand, each introduced conductive wire 1 is guided to the center hole 4a of the nipple 4, passes through a wire guide groove 18 formed at the tip of the nipple 4, and is further guided into the orifice 10 of the die 6. Note that it is preferable to heat the conducting wire 1 in advance.

的に製造される。Now, when a molten plastic material is supplied from the cylinder 11 (see FIG. 1), this plastic material passes through a passage 20 and is extruded into a passage 21 formed by the guide portion 12 of the nipple 4 and the die 6. . On the other hand, hollow tube 1
Inert gas is blown out from 6. Therefore, the plastic material is formed into a hollow shape and extruded as a plastic tube 22, and the conductive wires 1 are in parallel contact with the inner surface of the tube 22 and run toward the exit of the die. Therefore, the plastic tube containing the conducting wire 1 shown in FIG. 5 is manufactured continuously.

ーブの量産化を図ることができる。By the way, as mentioned above, when the conducting wires 1 which are twisted together in advance are prepared and the conducting wires 1 are introduced into the extrusion molding machine 9 while removing the twist, uniform tension is always applied to the plurality of conducting wires 1. It can be introduced into the extrusion molding machine 9 in this state. Therefore, even if the introducing speed of the conducting wire 1 is increased, it is possible to prevent the wire from breaking, and therefore it is possible to mass-produce the plastic tube containing the conducting wire.
