Abstract

PURPOSE:To freely vary pitches between conductive wires of a tape electric wire by varying an interval between a fixed roller and a moving roller according to the movement of the conductive wire. CONSTITUTION:When a moving roller 21 is moved in such a direction that an interval between the same and a fixed roller 2 becomes large, a variation ratio of a pitch of a conductive wire 8 at the interval becomes small while a pitch of a tape electric wire 10 becomes large. Namely, when the moving roller 21 is moved by operation of a linear moving means 22, a pitch of the conductive wire 8 of the tape electric wire 10 can be gradually varied according to the movement of the moving roller 21. If the tape electric wire 10 before and after the movement is cut out, it is possible to obtain the tape electric wire 10 where pitches of the conductive wire 8 are different at both ends.

According to the tape wire manufacturing apparatus of the present invention, when the conductor wire is accommodated in the accommodating peripheral grooves formed on the outer peripheral surfaces of the moving roller and the fixed roller and the conductor wire is run in the longitudinal direction, The pitch is determined by each accommodation circumferential groove.
Since the accommodating peripheral groove of the moving roller and the accommodating peripheral groove of the fixed roller are formed at different pitches, the conductor wire between the moving roller and the fixed roller is directed from the moving roller to the fixed roller by these accommodating peripheral grooves. Forced to change the pitch at a constant rate. Therefore, the pitch of the lead wires of the tape electric wire covered with the insulating tape by being sandwiched by the rolls is determined by the spacing dimension of each accommodation circumferential groove and the spacing dimension between the moving roller and the fixed roller. In this state, the linear moving means is operated to move the moving roller, and the distance between the moving roller and the fixed roller is changed, whereby the pitch of the lead wire of the tape electric wire can be arbitrarily changed. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the tape electric wire manufacturing apparatus according to the present invention will be described below with reference to FIGS. In each of these drawings, reference numeral 20 is a manufacturing apparatus, 21 is a moving roller, and 22 is a linear moving means. In this embodiment, the same parts as those of the conventional manufacturing apparatus 1 are designated by the same reference numerals to simplify the description.

As shown in FIGS. 1 and 2, the manufacturing apparatus 20 of this embodiment has a cylindrical fixed roller 2 arranged in a horizontal state and a pair of fixed rollers 2 arranged at a parallel interval. It is common to the conventional manufacturing apparatus 1 in that it is provided with the heating roll (roll) 23, the insulating tape feeding device 6, the window punching device 11 and the like. However, the manufacturing apparatus 2 of the present embodiment
0 is different from the manufacturing apparatus 1 of the conventional example in that the movable roller 21 is arranged at the rear stage of the fixed roller 2.

Each of the fixed roller 2 and the movable roller 21 is formed with an accommodating circumferential groove 7 for accommodating the conducting wire 8 on its outer peripheral surface. The pitch of the accommodation circumferential groove 7 of the fixed roller 2 is P ₂ , the pitch of the accommodation circumferential groove 7 of the moving roller 21 is P ₁ , and P ₁ <P ₂ . The distance between the moving roller 21 and the heating roll 23 arranged in the subsequent stage is L ₁ , and the distance between the fixed roller 2 and the moving roller 21 is L ₂ .

The moving roller 21 is provided with a linear moving means 22 for linearly moving the moving roller 21 in the traveling direction of the conductor 8. The linear moving means 22 is composed of, for example, a servo motor 22a and a ball screw 22b, and moves together with a support base 24 that rotatably supports the moving roller 21.
1 and is adapted to vary the spacing dimension L ₁ between the distance dimension L ₂ and a heating roll 23 and the fixed roller 2 is linearly moved.

In order to manufacture the tape electric wire 10 in which the pitch P of the conductors 8 is changed by the manufacturing apparatus 20, the conductors 8 are arranged in the accommodating circumferential grooves 7 of the movable roller 21 and the fixed roller 2 while being accommodated therein. The conductor 8 is run in the longitudinal direction.
At this time, at the position where the moving roller 21 and the fixed roller 2 are spaced from each other, the pitch P ₁ ·
Due to the difference in P ₂ , the pitch P of the conductor wire 8 gradually changes from P ₂ to P ₁ , and the conductor wire 8 of the tape electric wire 10 as a product is
The pitch P (the pitch P of the conductor 8 at the position of the holding roller 3) is also located on the extended line of the conductor 8 between the rollers 2 and 21.

In this state, the linear moving means 22 is operated to change the distance L ₂ between the moving roller 21 and the fixed roller 2 and the distance L ₁ between the moving roller 21 and the heating roll 23. For example, when the moving roller 21 is changed in a direction in which the distance L ₂ between the moving roller 21 and the fixed roller 2 increases, the rate of change in the pitch of the conductor wire 8 at the distance is reduced and the pitch P of the tape electric wire 10 increases. Can be changed to. That is, when the moving roller 21 is moving by the operation of the linear moving means 22, the pitch P of the conductor wire 8 of the tape electric wire 10 is gradually changed in accordance with the movement of the moving roller 21, By cutting out the tape electric wires 10 before and after this movement, as shown in FIG. 4, the tape electric wires 10 having different pitches of the conductive wires 8 at both ends can be formed. 1 and 2, reference numeral 27 is a cutting device for cutting the tape electric wire 10 at the position of the window portion 12, and 28 is a pitch P of the tape electric wire 10 to finely adjust the moving amount of the moving roller 21. Is a lead wire feeding roller, and 30 is a tape wire take-up roller.

Here, the dimensional relationship of each portion in the manufacturing process of the tape electric wire 10 will be schematically described with reference to FIG. The pitch P of the accommodation circumferential groove 7 of each roller 21.2
_When the inclination angle of the conductor wire 8 due to the difference of ₁ · P ₂ is θ ₁ , the pitch P ₁ of the accommodation circumferential groove 7 of the moving roller 21 and the tape wire 10
The relationship with the pitch P _x of the conducting wire 8 a having the following relationship is P ₁ = P _x + L ₁ × tan θ ₁ ... From this equation, there is a relationship of tan θ ₁ = (P ₁ −P _x ) / L ₁ ... The relationship between the pitch P _x of the conductor 8 of the pitch P ₂ and the tape wire 10 of the housing circumferential groove 7 of the fixed roller _{2, P 2 = P x + (} L 1 + L 2) × tanθ 1 ····· relationship that ... In other _{words, tanθ 1 = (P 2 -P} x) / (L 1 + L 2) ········ '. From these equations 'and', if θ ₁ is eliminated, the following relationship is derived: P _x = P ₁ −L ₁ × (P ₂ −P ₁ ) / L ₂ ... On the other hand, in the conductor 8b arranged next to the conductor 8a, if the inclination angle is θ ₂ , then 2 × P ₁ = P _x + P _y + L ₁ × tan θ ₂ ... Become. From this equation, there is a relationship of tan θ ₂ = (2 × P ₁ − (P _x + P _y )) / L ₁ ... Further, the relationship between the pitch P ₂ of the accommodation circumferential groove 7 of the fixed roller 21 and the pitch P _y of the conductor 8b of the tape electric wire 10 is 2 × P ₂ = P _x + P _y + (L ₁ + L ₂ ) × tan θ ₂ · ........ That is, there is a relationship of tan θ ₂ = (2 × P ₂ − (P _x + P _y )) / (L ₁ + L ₂ ). If θ ₂ is eliminated from these equations 'and', P _x + P _y = 2 × P ₁ -2 × L ₁ × (P ₂ −P ₁ ) / L ₂ ... From the relationship with the equation, P _y = P ₁ −L ₁ × (P ₂ −P ₁ ) / L ₂ ... Therefore, P _x = P _y ..., And by changing L ₁ and L ₂ according to the formula, the pitch P of the conductors 8 of the tape electric wire 10 can be arbitrarily set at equal intervals. It will be possible to form.

An example of manufacturing the tape electric wire 10 by using such a manufacturing apparatus 20 will be described. Pitches P ₁ and P ₂ of the accommodating peripheral grooves 7 of the movable roller 21 and the fixed roller ₂
By setting P ₁ = 1.10 mm and P ₂ = 1.50 mm, the pitch P of the conductors 8 at both ends of the length of 300 mm is P = 1.0 mm and 0.8 mm, as shown in FIG. , The tape electric wire 10 can be obtained, and the excess insulating tape 9 is cut off by the cutoff line 25 shown by the chain line in the figure, or the mounting hole 26 shown by the broken line is provided, so that the tape electric wire 1 as a product can be obtained.
You can get 0.

Furthermore, since the insulating tape 9 is adhered by heating, it is possible that the insulating tape 9 contracts after heating and the pitch P of the conductors 8 fluctuates. It is possible to move the roller 21 and set in advance the pitch P of the conductive wire 8 in consideration of shrinkage, which is advantageous in that the quality of the product can be improved.

Adopt 22. The movable roller 21, the fixed roller 2 and the like are arranged horizontally, but instead of this, any arrangement such as vertical arrangement may be adopted. The pitch P ₂ of the housing circumferential groove 7 of the fixed roller 2 moves roller 2
Although the pitch is set to be larger than the pitch P _{1 of the first} accommodation circumferential groove 7, instead of this, it is configured to satisfy the relationship of P ₂ <P ₁ . Although the movable roller 21 is arranged at the rear stage of the fixed roller 2, instead of this, the movable roller 21 is arranged at the front stage of the fixed roller 2. Set the number and spacing of the conductors arranged in the tape wire to any value.
