However, in this tape electric wire manufacturing apparatus, the punched portion is not required when the holes are formed in the insulating tape as described above, and the connection provided for continuous transportation is eliminated. Since the parts are unnecessary, there is a problem that the material cost becomes high. Also,
When changing the size of the hole, that is, when the different types of products are produced, it is necessary to change the setup of the press device, which causes a problem of low production efficiency. Furthermore, there is a problem that the operating noise of the press machine is loud. In order to solve these problems, we considered a method of feeding the insulating tape while cutting it on the above heat roll, and sequentially attaching it to the conductor.However, when this method is adopted, the heat roll (transport Insulation tape (sheet material) comes off from the
There is a problem that it is difficult to hold the insulating tape at a predetermined position up to the conductor sticking position.

[0007]

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A sheet material conveying device and a tape electric wire manufacturing device according to an embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 in FIG. 1 indicates a tape electric wire manufacturing apparatus. This tape electric wire manufacturing apparatus 1 is arranged so that a plurality of rectangular conductors 2 are arranged in parallel with each other in a direction penetrating the plane of FIG. And then rolls 3, 4
Then, the direction is changed, the position is determined, and the sheet is fed in a vertical direction at a predetermined speed. Then, on both sides of the conductor 2 fed in the vertical direction, a pair of metal temporary heating rolls 6 for temporarily attaching the insulating tape 5 to both sides of the conductor 2 by heat.
Are arranged horizontally. Here, this temporary heating roll 6
Rotates at a peripheral speed such that its tangential speed is equal to the feed speed of the conductor 2. A feeding device 7 for feeding the insulating tape 5 at a predetermined speed is provided on the side of each temporary heating roll 6 opposite to the conductor 2, and between each feeding device 7 and each temporary heating roll 6. Includes a pair of tape feeding rolls 8 for feeding the insulating tape 5 fed from the feeding device 7, two dancer rolls 9 and an insulating tape for keeping the tension of the insulating tape 5 constant by changing the mutual distance. A pair of feed rolls 10 are provided for feeding the temporary heating rolls 6 while controlling the speed of the rolls 5. Further, on the upper side of each temporary heating roll 6,
The insulating tape 5, which is fed along the upper portion of the outer peripheral surface of the temporary heating roll 6 and is directed between the temporary heating rolls 6, is constantly rotated by the cutting edge 11 of the insulating tape 5 while being rotated. A cutter roll 12, which is a cutting means, is provided, the rotation speed of which is controlled so that a predetermined length can be cut at a position.

Below the temporary heating roll 6, there is provided a rubber bound thermal roll 13 for completely sticking the insulating tape 5 temporarily attached by the temporary heating roll 6 onto the conductor 2.
Two cooling rolls for cooling the tape electric wire (having the insulating tape 5 completely attached to both sides of the conductor 2) 14 sent from the book-equipped heat roll 13 further behind the book-equipped heat roll 13 in the feeding direction. A slit device 1 is provided at the rear of which a width of both ends of the tape electric wire 14 is slightly cut to finish the tape electric wire 14 to a standard width.
6, a take-up device 19 for taking up the tape electric wire 14 and a take-up device 20 for taking up the tape electric wire 14 are sequentially provided.

Further, in this embodiment, the electrostatic electrodes 2 are provided in front of and behind the cutter roll 12 in the conveying direction.
1, 22 are provided so as to face the outer peripheral surface of the temporary heating roll 6. As shown in FIG. 2, the electrostatic electrodes 21 and 22 are electrically connected to a temporary heating roll 6 made of metal through a high-voltage power supply 23. A static electricity is generated on the insulating tape 5 conveyed by.

In this embodiment, the insulating tape 5 described above is a sheet material. Then, the electrostatic electrode 21,
The high-voltage power supply 22 and the high-voltage power supply 23 constitute a static electricity generating device 24, and the temporary heating roll 6 constitutes a conveying means, which mainly constitute the sheet material conveying device of this embodiment. Depending on the sticking property of the insulating tape 5 to the conductor 2, it is possible to dispose the temporary heating roll 13 instead of the temporary heating roll 6 and omit the temporary bonding.

A tape electric wire manufacturing apparatus 1 having the above configuration
According to the above, the insulating tapes 5 fed by the feeding rolls 10 at a predetermined feeding speed are fed at the same speed along the outer peripheral surface of each temporary heating roll 6. Then, the insulating tapes 5 are provided on the outer peripheral surface of the temporary heating rolls 6 on the front side of the cutter rolls 12 in the transport direction, and the static electricity generating devices 24
Each of the electrostatic electrodes 21 is attracted to each temporary heating roll 6 by the static electricity generated on the insulating tape 5 (see FIG. 3. However, the operation of each insulating tape 5 and each cutter roll 12 etc. Since it is the same, only one side is shown in FIGS. Then, in a state where each insulating tape 5 is fed for a predetermined length while maintaining this suction state, each rotating cutter roll 12 cuts its cutting edge 11 (the top vertex position of the temporary heating roll 6). The insulating tapes 5 are cut at the same time by the cutting edge 11 (see FIG. 4), and the cut insulating tapes 5 are cut by the cutter rolls 1.
At the position on the rear side in the transport direction from the cutting position by 2, the electrostatic attraction force to each temporary heating roll 6 is further strengthened (or slightly weakened) by the static electricity generated on the insulating tape 5 by each electrostatic electrode 22. Electrostatic attraction is supplemented)
It will be. Here, almost at the same time as the completion of the cutting, the rotation speed of the feed roll 10 is temporarily delayed by a predetermined speed so that the trailing end portion of the insulating tape 5 that has already been cut and the leading end portion of the insulating tape 5 that will be cut next. A predetermined space is provided between the two (see FIG. 5). That is, this distance becomes the length of the conductor lead-out portion 25 (L shown in FIG. 6).

In this way, each of the cut insulating tapes 5 is at the same time kept in the adsorbed state at the same time as each temporary heating roll 6
It is sent in synchronization with the conductor 2 and is temporarily attached to the conductor 2 by heat. Then, by being temporarily attached, each insulating tape 5 separates from each temporary heating roll 6 and the conductor 2 is continuously conveyed.
After being sent in a state of being held by the heating roll 13 with the book, the tape wire 14 is completely attached to the tape roll 14, cooled by the cooling roll 15, and finished by the slit device 16 to a standard width. It will be wound up by the winding device 20 through.

It should be noted that it is also possible to employ a device for maintaining a constant gap between the temporary heating rolls 6 or the main heating rolls 13. This prevents the conductor 2 from moving on the rolls 6 and 13 when the insulating tape 5 is attached to the conductor 2, and stabilizes the pitch of each tape electric wire 14.
It is possible to prevent bonding failure.

As described above, according to this embodiment,
The static electricity generation device 24 generates static electricity on the insulating tape 5 which is a sheet material, and the static electricity causes the insulating tape 5 to be adsorbed to the temporary heating roll 6. Therefore, the insulating tape 5 cut from the temporary heating roll 6 can be satisfactorily transported to the position where the conductor 2 is attached without dropping. Moreover, since the positional deviation or the like does not occur on the temporary heating roll 6, the pass line can be stabilized and the meandering of the insulating tape 5 can be prevented.

Therefore, the conductor tape outlet portion 2 is attached to the insulating tape 5.
Since it is not necessary to form a hole for forming 5 by punching with a press device, and it is not necessary to provide unnecessary portions for both ends of the insulating tape 5 for continuous conveyance, the width of the tape electric wire 14 is eliminated. Only the part that is cut to finish (the part outside the chain double-dashed line Y shown in FIG. 6) becomes unnecessary waste, and the amount can be drastically reduced to reduce the material cost. Also, since the above holes are not required, it is of course unnecessary to change the setup of the punching press device when different types of products are produced, so the production efficiency is greatly improved, and the operating noise of the press device is eliminated, and the working environment is extremely high. Will be good.
Furthermore, different types of products can be easily produced simply by changing the rotation speeds of the feed roll 10, the cutter roll 12, and the like.

Further, in order to form the conductor lead-out portion 25,
Insulation tape 5 that has been cut and insulation tape 5 that is cut next
A space is provided between the conductor 2 and the insulating tape 5 on the temporary heating roll 6 to which the conductor 2 and the insulating tape 5 are attached. Since the distance is short and the insulating tape 5 has the same pass line on the temporary heating roll 6, the positional deviation of the bonding is extremely small. For the same reason,
Since it is easy to align the insulating tapes 5 with each other when the apparatus is started up, the initial adjustment time can be greatly shortened, and the waste generated for the initial adjustment can be reduced.

Although the sheet material conveying apparatus of the present invention is applied to a part of the tape electric wire manufacturing apparatus 1 in the above embodiment, the present invention is not limited to this.
For example, as shown in FIG. 7, in contrast to the above embodiment, the conductor is not conveyed, and instead of one of the insulating tapes, the tape electric wire 14
In place of the other insulating tape, a reinforcing plate tape 26 for improving strength or an imide tape 27 for improving heat resistance and preventing bending is provided,
The imide tape 27 and the imide tape 27 are electrostatically attracted to the heat roll 28, and are cut into a predetermined length by the cutting edge 11 of the cutter roll 12, and the cut reinforcing plate tape 26 or the imide tape 27 is fed by the heat roll 28 to both heat rolls 28. A device for applying the tape wire 14 so as to straddle the conductor outlet 25 of the electric wire 14 (in this case, the cutter roll 12 and the electrostatic electrodes 21, 22 of the static electricity generator are provided only on the side to which the reinforcing plate tape 26 or the imide tape 27 is fed. Or a device for attaching a coverlay film, or any other device that needs to convey a sheet material.

[0021]

As described in detail above, according to the sheet material conveying device of the present invention, the static electricity generating device generates static electricity on the sheet material, and the static electricity causes the sheet material to be attracted to the conveying means. Therefore, it is possible to easily prevent the sheet material from falling out of the transporting means, misalignment, and the like, and it is possible to accurately transport the sheet material.

Further, according to the tape electric wire manufacturing apparatus of the present invention, the insulating tape before the conductor is attached is cut to a predetermined length on the hot roll by the cutting means. Since static electricity is generated in the heat roller and the insulating tape is electrostatically attracted to the heat roller, the insulating tape cut from the heat roller does not fall off or shift in position. Therefore, it is not necessary to provide the insulating tape with a connecting portion for continuous conveyance, and it is not necessary to previously provide a hole in the insulating tape with a pressing device. Therefore, unnecessary parts punched out at the time of hole production and connecting parts for continuous transportation are eliminated, so the material cost of the insulating tape can be reduced, and since a press device is not required, the production efficiency at the time of different product production is improved and Noise is reduced.
