Description

[Detailed Description of the Invention] [Industrial Field of Application] An example of the use of the tape electric wire is shown in FIGS. 5(a) and 5(b).

10 is the entire tape electric wire, 12 is its conductor, 14 is an insulating coating, and 16 and 18 are connectors attached to both left and right ends.

In addition, in FIG. 5(a) and the following FIG. 6, the conductor 12 is
Indicated by a solid wooden line.

Since one connector 16 has a wide contact distance, the distance between the conductors 12 connected thereto is also wide at the ends of the wires. In this way, the distance between the conductors 12 widens at the ends.
Jillo is obtained by cutting (for example ABIII) from a long tape conductor 1; 110 in which the spacing of the conductors 12 increases periodically as shown in the ttS6 diagram.

The present invention relates to an apparatus for continuously manufacturing tape electric wires 10 in which the spacing between conductors 12 changes periodically, as described in ``2''.

[Prior Art] In FIG. 7, 20 is a feed drum for the conductor 12, 22 is a wire straightener, 24 is a guide roller, and 26 is the first insulating coating 1.
4a drum.

28 is a first laminating roll, which consists of rollers 30 and 32. The rough roller 32 consists of double rollers 34 and 36 combined as shown in FIG.

As shown in FIG. 9, the inner roller 34 has grooves 35 at regular intervals on its outer periphery. The combination is such that a portion thereof is exposed through a slit 38 provided in the outer roller 36.

The outer periphery of the outer roller 36 has the same number of grooves as the grooves 35 described above.
Grooves 40 are formed that match the grooves 35 at the roller end (slit portion) and are spaced apart in other areas as shown in FIG. 10.

42 is a drum for the second insulating coating 14b, 44 is a second lamination I roll, and 46 is a winding drum.

-1- The rollers 34 and 36 intersect under different shafts.
Rotate to . Then, for a certain period of time, the plurality of conductors 12 run while being sorted by the grooves 35 so as to maintain parallel distances. Next, the spacing between the conductors 12 is temporarily widened by the groove 40, and then narrowed by the groove 35 so as to maintain a parallel distance, and by repeating this, a plurality of conductors 1
2 is inserted between the insulating coatings 14a and 14b, and the tape electrical cable ! ! 10 is 1).

[Problems to be Solved by the Invention] In the above case, the distance between the conductors 12 is determined by the distance between the grooves 35 and 40. Therefore, in order to change the spacing between the conductors 12, rollers 34 and 36 with a different groove spacing,
I have to replace it.

[Means for solving the problems] This invention aims to solve the above problems.
~ As shown in Figure 4, (1) A large number of grooves 70 are provided on the side surface in a direction approximately perpendicular to the axis, into which the conductors 12 can fit and run, and the grooves are continuous with equal intervals maintained. (2) A reversing guide roll 68, which is gradually spread out, is rotatably provided immediately before the heating, pressurizing, and integrating device; (2) it is intermittently stopped and rotated at preset time intervals; and inverting.

[Example] In Figure 1, 20 is a delivery reel for the conductor 12;

22 is a wire straightener, and 24 is a guide roller.

50 is a pair of upper and lower guide plates.

52 is a guide roll.

Reference numerals 54 and 56 are delivery reels for the insulation coating 14.

58 is a hot air nozzle.

60 is a pair of pressure rollers.

62 is a measuring device.

64 is Yapstan in the afternoon.

66 is a presser roller.

46 is a drum for winding up the finished tape electric wire 10.

68 is a guide roll, which is unique to this invention.

A large number of grooves 70 are provided on the side surface thereof in a direction substantially perpendicular to the axis, with the intervals continuously changing while maintaining equal intervals (FIGS. 2 to 4). In other words, as shown in Fig. 4, the spacing between the grooves 70 is the narrowest at any one line, and then gradually widens as it goes around the side, until it reaches its maximum near 2π, that is, after about one revolution. .

Then, the conductor 12 is allowed to run while contacting the bottom of each groove 70 one by one.

To change the spacing between the conductors 12, the guide roll 68 may be rotated in one direction by an appropriate angle, and to return to the original spacing, the guide roll 68 may be reversed in the opposite direction.

In FIG. 1, 71 is a pulse motor for rotating the guide roll 68 intermittently to a set position. a cam 72 (having two protrusions 74 and 76) interlocked with the measuring device 62 in order to send a signal to the pulse motor 71;
A switch 78 and an amplifier 80 are provided which are operated thereby.

[Function] (1) The narrowest distance between the grooves 70 of the guide roll 68 is assumed to be 00 (FIG. 4).

Initially, it is assumed that the conductor 12 travels while contacting the groove 70 near θ°, and the guide roll 68 is stopped at such a position.

At that time, as shown in FIG.
It is o.

Such a conductor 12 is sandwiched between insulation coatings 14, heated with a hot air nozzle 58, and crimped with a roll 60 to form a tape electric wire 10. The drum 46 is then passed through a metering device 62.
Wind it up.

(2) As the measuring device 62 rotates, the cam 72 rotates in the direction of the arrow in FIG. ), the guide roll 68 is moved by the pulse motor 71.
rotates by 01 and stops (T2).

Then, since the conductor 12 runs while contacting the grooves 70 with widened intervals, the interval becomes wide pl.

(3) Next, when the protrusion 76 of the cam 72 activates the switch 78 (T3 in FIG. 6), the guide roll 68 is reversed.
Also, the interval is p. Return to state.

Repeat this below.

(4) Wider the spacing between the conductors 12, for example p in FIG.
If you want to set it to 2, you just need to rotate the guide roll 68 by 02.

[Effects of the Invention] A large number of IMs 70 each having a conductor 12 inserted into the side surface and capable of running are provided in a direction substantially perpendicular to the axis, and the intervals between them are continuously and gradually widened while maintaining equal intervals. Since the guide roll 68 is rotatably provided just before the heating/pressurizing and integrating device, the spacing between the conductors 12 can be changed simply by changing the rotation angle of the guide roll 68.
