It has become.

Reference numeral 17 in the drawing denotes a roller 17 as shown in FIG.
It is a pitch roller 17 in which grooves 17a are formed on b at a constant pitch, and ball screws 19 are provided at both ends of the pitch roller 17 along the vertical direction. These ball screws 19 can drive both ends of the pitch roller 17 up and down by being driven by the servo motor 18. The servo motor 18 and the hole screw 19 tilt the pitch roller 17 with respect to the horizontal direction. An angle adjusting means for adjusting the inclination angle is configured.

Reference numeral 14 is a pair of horizontal auxiliary rollers for returning a plurality of conductors 1 ... Having a required inclination angle, which have run on the groove 17a of the pitch roller 17, to a horizontal state and sending them out. . And the pitch roller 17

This is to prevent unevenness in the slip of the conductors 1 ... When the conductors 1 ... Traveling on the pitch rollers 17 are returned to the horizontal state.

Insulating tape feeding devices 11 for feeding the insulating tape 2 so as to sandwich the conductors 1 fed from the auxiliary roller 14 are arranged on both sides of the conductors 1 ... A perforation insertion device 12 for inserting a perforation 2b into the insulating tape 2 that has been sent out, and a perforation 2b formed by the perforation insertion device 12 in front of the device 11 in the delivery direction.
A brake roll 13 which is an auxiliary means for cutting the insulating tape 2 is provided. And further,
A first heating roll 15 and a second heating roll 16 for temporarily adhering and permanently adhering the insulating tape 2 that has passed through the perforation inserting device 12 and the conductors 1 ... It is provided.

The tape wire 10 is manufactured by using the tape wire manufacturing apparatus having the above structure.
The method of manufacturing the tape electric wire in 1 will be described with reference to the same FIG. 1 of the above manufacturing apparatus. First, a plurality of conductors 1 made of copper, copper alloy or the like are prepared. The conductors 1 ... Are grooved 17a of the pitch roller 17 which is inclined at a required inclination angle θ from the horizontal state as shown in FIG.
... By running over, the conductor 1 ...
At the same inclination angle θ as the pitch roller 17, they are sent out in a state where they have a constant pitch in the same plane. Further, the conductors 1 ... Delivered at the inclination angle θ are passed through the auxiliary roller 14 for arranging the conductors in the horizontal direction again.

On the other hand, the insulating tape 2 made of thermo-flexible plastic sent from the insulating tape sending device 11 is
By passing through the perforation inserting device 12, cutting perforations 2b are attached in the lateral direction at desired intervals, and are fed out in the horizontal direction through between the opposing brake roll 13 and the auxiliary roll 14. The conductors 1 ... Are inserted so as to sandwich them.

Then, the conductors 1 ... And the insulating tape 2 arranged so as to sandwich the conductors 1 are passed through a preheating roll 15. Then, during or after passing through the preheating roll 15, only the insulating tape 2 is covered with the brake roll 13.
By intermittently applying a brake to slow the running speed or stop running, the insulating tape 2 is cut at the perforations 2b to form the conductor exposed portion 1a.

By repeating the above-described operation and changing the inclination angle of the pitch roller 17 while alternately moving both ends of the pitch roller 17 up and down by each servo motor 18, as shown in FIG. It is possible to obtain the continuous continuous tape body 20 for tape electric wire with the pitch changed. For example, as shown in FIG. 5, when a roller having a pitch γ between grooves is inclined at an angle θ with respect to the horizontal direction, the pitch between conductors traveling on the roller 17 is:
γ cos θ. That is, the pitch between the conductors becomes narrower as the inclination angle of the roller 17 is increased.

Therefore, using the manufacturing method and apparatus of the first embodiment as described above, a manufacturing example of manufacturing the tape electric wire 10 obtained when the pitch rollers 17 having various pitches are changed to respective required angles θ Will be described below. (Production Example 1) In the present Production Example 1, the above-described Example 1 is used.
As the pitch roller 17 of the tape electric wire manufacturing apparatus in FIG. Then, the pitch roller 17 was fixed by inclining θ by about 50 degrees from the horizontal direction, and the method of manufacturing the tape electric wire of the above-mentioned Example 1 was carried out. As a result, the produced tape electric wire had a pitch between conductors of 0.8 mm.

Under the same conditions as in Manufacturing Example 1 above, the inclination angle of the pitch roller 17 was set to θ = 37 degrees, and this was fixed, and the tape wire manufacturing method described in Example 1 was carried out. The manufactured tape electric wire 10 had a pitch between conductors of 1.0 mm.

(Manufacturing Example 2) In this Manufacturing Example 2, a pitch roller having a kerf pitch of 1.00 mm was used as the pitch roller 17 of the tape wire manufacturing apparatus in the above-described Example 1. Then, the pitch roller 17 is moved from the horizontal direction by θ.
= About 37 degrees was tilted and fixed, and the method for manufacturing the tape electric wire of Example 1 was carried out. As a result, the produced tape electric wire 10 has a pitch between conductors of 0.8 mm.
It was something that had.

(Manufacturing Example 3) In Manufacturing Example 3, a pitch roller having a kerf pitch of 0.80 mm was used as the pitch roller 17 of the tape wire manufacturing apparatus in the above-described Example 1. Then, the pitch roller 17 is moved from the horizontal direction by θ.
= Fixing by inclining by about 51 degrees, the method of manufacturing the tape electric wire of Example 1 was carried out. As a result, the manufactured tape electric wire 10 has a pitch between conductors of 0.5 mm.
It was something that had.

The pitch between the conductors of the tape electric wire 10 shown in the above-described manufacturing example is the slip of the conductors 1 ... When returning the conductors 1 ... Taking into consideration the influence of the shrinkage ratio of 2 etc., while detecting the pitch between conductors with a conductor pitch measuring device, etc.,
It is possible to automatically correct by slightly moving the pitch roller 17 up and down by interlocking a feedback mechanism.

In the first embodiment, the insulating tape 2
By installing a perforation insertion device after sending
Although the case where the perforations 2b are provided on the insulating tape 2 has been shown, an insulating tape pre-perforated may be used without providing the perforation inserting device. However, the perforation 2b is previously
When using the insulating tape provided with the, the perforation of each of the two insulating tapes 2 sandwiching the conductor 1 is the auxiliary roll 1
After passing 4, it must be in the same position.
Further, it goes without saying that the conductor exposed portion 1a may be formed by punching out the window portion 42b as described in the conventional example.

As described above, in the continuous tape body 20 for a tape electric wire manufactured by the method and apparatus for manufacturing a tape electric wire according to the first embodiment, the continuous tape in which the pitch between the conductors is cyclically changed. It is possible to manufacture the body 20, and when the conductor exposed portion 1a is cut into the tape electric wire 10, the pitch between the conductors of the left and right cut lead portions is different at both ends,
It can be applied to connection between devices with different pitches.

By providing angle adjusting means on the pitch roller 17 of the apparatus of this embodiment and freely changing the angle, the pitch between the conductors traveling on the pitch roller 17 can be freely changed. For example, when a roller having a pitch γ between grooves is inclined at an angle θ with respect to the horizontal direction, the pitch between the conductors traveling on the pitch roller 17 is γ cos θ. That is, the larger the inclination angle of the pitch roller 17, the narrower the pitch between conductors.

The pitch between the conductors 1 traveling on the slanted pitch rollers 17 is the pitch rollers 17
Γco does not always occur due to errors due to slippage and slippage between conductors that occur when the vehicle travels above and is returned to the horizontal state again.
It is conceivable that the distance sθ is not maintained and a slight deviation may occur. However, by providing the pitches between the grooves of the pitch rollers 17 at a constant interval, the error in the pitch between the conductors becomes small, and it is accurate. The pitch between conductors can be controlled. Further, it is easy to correct the pitch deviation between the conductors by interlocking a feedback mechanism with the pitch angle adjusting means of the pitch roller.

Further, in the past, when the material of the insulating tape was changed, the pitch rollers were also changed to those having different pitches due to the difference in shrinkage ratio. However, in the tape wire manufacturing apparatus of this embodiment, The pitch can be finely adjusted by the angle adjusting means, and it can be dealt with without exchanging the pitch roller.

Further, although the pitch roller 17 in which the grooves 17a having a constant pitch as shown in FIG. If small, groove 17a
It is possible to use the one without.

[0035]

Therefore, in the tape electric wire of the present invention, since the conductor pitches at the lead-out portions of the left and right cut portions are different, the tape electric wire can be applied to the connection between devices having different pitches, and the printed wiring board can be used. Instead, the merit of an inexpensive tape electric wire can be fully exhibited.

Further, in the apparatus according to the third aspect, the pitch between the conductors traveling on the rollers can be freely changed by freely changing the angle of the rollers by the angle adjusting means. For example, when a roller having a pitch γ between the grooves is inclined at an angle θ with respect to the horizontal direction, the pitch between the conductors traveling on the roller is γ cos θ. In other words, the pitch between the conductors becomes narrower as the angle of inclination of the rollers increases, and the tape electric wire having an arbitrary pitch can be easily manufactured without changing the configuration of the manufacturing apparatus.
