CONSTITUTION:Insulating tapes 3 and 4 are supplied to heating rollers 5 and 6 which make a pair from the direction in which they are opposed to each other, and at the same time plural conductors 1 are guided by a guide roller 7 between the tapes 3 and 4 and are inserted in the condition where they are separated by the specified intervals from each other. The conductors 1 are bonded with both sides of the tapes 3 and 4 when passing through the heating rollers 5 and 6, and a continued tape cable T is formed. The tapes 3 and 4 are formed with rectangular conductor exposing windows by window opening press 8A and 8B prior to the supply to the roller 5 and 6, and are also formed with auxiliary windows 20 adjacent to them. Next, the wire T is sent to a reinforcing tape joining means 12 by converting rollers 10 and 11, and projector/light receiver 16a and 16b being a window detecting means detect whether the auxiliary windows 20 are met or not so as to make the position of a reinforcing tape 14 accurate.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a laminated electric wire, that is, a tape electric wire, in which both ends of a flat type are peeled off (stripped) in advance.

Traditionally, when connecting multiple printed circuit boards electrically,
For example, as shown in FIGS. 3 and 4, a plurality of conductive wires 1 are arranged parallel to each other at predetermined intervals, the conductive wires 1 are sandwiched between two pieces of insulating tape 3.4, and one By removing both ends 3a of the insulating tape 3, the conductor l
A tape electric wire T with both ends exposed is widely used.

Further, in such a tape electric wire T, in order to reinforce the exposed portion of the conductor 1, a reinforcing tape 9 is usually further bonded to the back side of the exposed portion.

Such a tape electric wire T was manufactured by a method as shown in FIG. That is, the insulating tape 3.4 is supplied to the pair of heating rollers 5.6 from mutually opposing directions. At the same time, a plurality of conductive wires 1 are guided by guide rollers 7 and inserted between both insulating tapes 3.4 at a predetermined distance from each other. When the conductor, i.e. the conductor l, passes through the heating roller 5.6, the double edge tape 3.4
The wire is sandwiched between the wires and both surfaces are coated and bonded to form a continuous tape wire T. Further, before one of the insulating tapes, in this example, the insulating tape 3 is supplied to the heating roller 5, a rectangular window 9 is formed using a window punching press 8. Therefore, each conductive wire 1 in the portion corresponding to the window 9 is not covered with the insulating tape 3.

The continuous tape wire T is then passed through turning rollers 10.11
The reinforcing tape is then fed to the reinforcing tape joining means 12. The reinforcing tape joining means 12 has a reinforcing tape shooter 13,
The shooter 13 attaches a reinforcing tape 14, which has a predetermined length and width and is rectangular in this example, to the side of the tape electric wire T where the window 9 is formed and where the conductor l is not exposed.
In this example, the tape is supplied to the lower side of the electric wire T. The reinforcing tape 14 is heated and pressed onto the tape electric wire T by a press heater 15 so as to adhere to the insulating tape 4 on the lower side of the tape electric wire T.

Since the reinforcing tape 14 needs to be adhered accurately to the position where the window 9 of the tape electric wire T is formed, conventionally the window detecting means 16 is placed extremely close upstream of the reinforcing tape joining means 12.
is provided, detects the window position, and activates the reinforcing tape shooter 13.
The press heater 15 was also configured to control the operating timing.

However, the conventional window detection means has a structure in which a light emitter 16a and a light receiver 16b are arranged one above the other with the tape electric wire T in between, and the window 9 of the tape electric wire T is detected.
The window detection means 16 detects the difference between the amount of light that passes through both the tapes 3.4 of the tape electric wire T and the amount of light that passes through the insulating tape 4 on one side, resulting in variations in detection accuracy and Accidents such as misalignment of joint positions frequently occurred.

Therefore, an object of the present invention is to provide a method for manufacturing a high-quality tape electric wire in which the joining position of the reinforcing tape does not shift.

(b) To make a profit - The above object is achieved by the method for manufacturing a tape electric wire according to the present invention. To summarize, the present invention supplies insulating tapes from opposite directions to a pair of heating rollers, and simultaneously inserts a plurality of conductive wires between both tapes at a predetermined distance from each other. In a manufacturing method in which a tape electric wire is manufactured by covering and adhering the conductive wire from both sides with double-sided tape,
At least one of the insulating tapes is formed with a conductor-like exposure window through which each conductor is exposed, and furthermore, at least one of each of the tapes is arranged in a positional relationship that matches when the two composite-edged tapes are joined. This method of manufacturing a tape electric wire is characterized in that an auxiliary window for detecting the conductor exposed window is formed along the longitudinal edge of the side.

41st Example Next, the method for manufacturing a tape electric wire according to the present invention will be explained in more detail with reference to the drawings.

FIG. 1 shows an embodiment of an apparatus for carrying out the method for manufacturing a tape electric wire according to the present invention. In this embodiment, the insulating tape 3.4 is fed from opposite directions to a pair of heating rollers 5.6.

At the same time, a plurality of conductive wires 1 are guided by guide rollers 7 and inserted between the two edge tapes 3.4 at a predetermined distance from each other. When the conducting wire 1 passes through the heating roller 5.6, it is sandwiched between the two edge tapes 3.4 and coated and bonded on both sides to form a continuous tape electric wire T. The above operation is similar to the conventional manufacturing method.

According to the invention, both edging tapes 3.4 are attached to heated rollers 5.4.
6, the window opening presses 8A, 8
A rectangular conducting wire exposure window 9 is formed at B. Therefore, each conductive wire 1 in the portion corresponding to the window 9 is not covered with the insulating tape 3.

In this embodiment, the conducting wire exposure windows 9 are formed on both of the bonded tapes 3.4, but it is also possible to form them on only one of the insulating tapes.

Furthermore, according to the present invention, the auxiliary window 20 is formed adjacent to the window 9 for exposing the conductor using the window punching presses 8A and 88. As will be explained later, the auxiliary window 20 is connected to the uragyo tape joining means 1.
It is used to control the operation timing of 2. The reinforcing window 9 does not necessarily have to be formed at the same time as the conductor exposure window 9,
It can also be formed using a press (not shown) other than the window punching presses 8A and 8B. However, both line edge tape 3.
The auxiliary window formed in 4 needs to be formed in a positional relationship that matches when both line edge tapes 3.4 are joined. Further, although the auxiliary window is formed along one longitudinal edge of the insulating tape, it is also possible to form it along another edge. Further, although the auxiliary window 20 is rectangular in this embodiment, it may be circular or may have any shape.

Furthermore, the conducting wire exposure window 9 and the σ auxiliary window 20 can be formed in advance on an insulating tape instead of being formed using presses 8A and 8B during manufacturing as in this embodiment.

The continuous tape wire T is then passed through turning rollers 10.11
The reinforcing tape is then fed to the reinforcing tape joining means 12. The reinforcing tape joining means 12 has a reinforcing tape shooter 13 similar to the conventional one, and the shooter 13 connects a reinforcing tape 14 having a predetermined length and width and having a rectangular shape in this example, and a tape electric wire in this example. If the conductive wire exposure window 9 is formed on only one insulating tape, it is supplied to the lower side of the T, or to the side where the conductor exposure window 9 is not formed. Next, reinforcing tape 14
In order to adhere to the insulating tape 4 on the lower side of the tape electric wire T,
The tape is heated and pressed onto the electric wire T by a press heater 15.

According to the invention, a window sensing means 16 is provided upstream and in close proximity to the reinforcing tape joining means 12.

The window detection means 16 includes a light emitter 16a and a light receiver 16b, and the light emitter 16a and the light receiver 16b are arranged above and below with the tape electric wire T in between, and detect the auxiliary window 9 formed on the tape electric wire T. According to the invention, the auxiliary windows 9 formed in both line edge tapes 3.4 are completely aligned, so that the auxiliary window portions are completely transparent. Therefore, the window detection means 16 can detect the auxiliary window 9 with extremely high accuracy. Furthermore, if the auxiliary window 20 of the wire edge tape 3.4 does not match and the window detection means 16 detects an abnormality, the entire apparatus is stopped and the supply of the insulating tape 3.4 is restarted. be adjusted.

By detecting the position of the auxiliary window 20 by the window detection means 16, the detection signal is transmitted to the reinforcing tape joining means 12 via the control means (not shown), and the reinforcing tape shooter 13 and press heater 15 are The timing of operation is controlled, so that the reinforcing tape 14 is always accurately bonded to the position of the conductor exposure window 9.

Next, the tape electric wire T to which the reinforcing tape 14' has been joined is cut off at its longitudinal end edge by a selvage cutter 30, and then by a transverse cutter 40 to cut the tape electric wire T into the conductor 1!
The IN bay window 9 portion is cut, and a tape electric wire T having a predetermined size is manufactured.

As described above, the method for manufacturing a tape electric wire according to the present invention is to attach the longitudinal edge ends to both wire edge tapes that cover a conductor wire in a positional relationship that matches when the both wire edge tapes are joined. An auxiliary window for window detection is formed along the auxiliary window, and the joining of the reinforcing tape to the conductor exposed window is controlled by detecting the auxiliary window, so that the position of the reinforcing tape does not shift.
It has the advantage of being able to produce high-quality tape electric wires.
