Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to FRP prepreg tape (hereinafter referred to as FRP tape).
The present invention relates to a sticking device, and more particularly to a device for automatically sticking a FRP tape on a predetermined mold. In particular, according to the present invention, the trouble due to the sticking of the FRP tape to the roll is eliminated, and the positional fluctuation in the width direction of the FRP is significantly reduced, and the FR for a predetermined mold is reduced.
The present invention relates to improving the accuracy of P-tape attachment position.

[Conventional technology]

The construction of a conventional automatic sticking device for FRP tape 12 is shown in FIGS. 2 and 3. The FRP tape 12 to be used has a protective sheet 13 on one side and a plastic film 15 on the other side and is wound around a supply reel 10. The FRP tape 12 is sandwiched by feed rolls 16 and 14, and is fed downward from the supply reel 10 as the rolls rotate. The feed roll 16 is a rubber roll, and 14
Is a metal roll. At this time, the feed roll 16 contacts the plastic film 15 attached to the FRP tape 12 and the feed roll 14 contacts the protective sheet 13 attached to the FRP tape 12. FRP downstream of feed rolls 16 and 14
There is a detection device 20 for detecting the edge position of the tape 12, and there is a roll group 18 whose axis is rotated by a signal emitted by the detection device 20, and when the FRP tape 12 is displaced in the width direction, this roll group 18
Rotates in response to a signal from the detection device 20 to correct the position of the FRP tape 12 in the width direction.

In this case, the FRP tape 12 does not adhere to each roll because the plastic film 15 of the FRP tape 12 or the protective sheet 13 is in contact with each roll and the FRP tape 12 itself having direct adhesiveness does not directly contact with each roll. After the FRP tape 12 has passed through the roll group, the plastic film 15 attached to the FRP tape 12 is wound up by the roll 28, and thereafter only the protective sheet 13 is attached to the FRP tape 12. Thereafter, the FRP tape 12 does not cut the protective sheet 13 by a cutting device (not shown), but only the FRP tape 12 is cut to a predetermined length and proceeds downward, and is pressed and stuck to the mold by the sticking roll 22. Only the remaining protection sheet 13 is wound around the take-up reel 30.

[Problems to be Solved by the Invention]

The first problem with the prior art is that the plastic film 15 is not attached to the FRP tape 12 and is simply a protective sheet.
In recent years, the number of only 13 has been increased.
Therefore, the FRP tape 12 directly contacts the surface of one of the feed roll 16 roll group 18.

There are various configurations of the FRP tape 12, but a typical one is a carbon fiber impregnated with an uncured epoxy resin and formed into a tape shape, and the FRP tape 12 itself has adhesiveness. Therefore, only the protective sheet 13 is adhered and the plastic film 15
When using the unattached FRP tape 12, the FRP tape 12 adheres to the surface of the feed roll 16 or roll 18 and FR
It becomes difficult to feed the P tape 12 smoothly downward.

The second problem is that the FRP tape 12 is the feed roll 16,14
The FRP tape 12 is moved between the feed rolls 16 and 14 by being sandwiched between the feed rolls 16 and 14 and is moved rightward in the width direction of the FRP tape 12. Alternatively, the position changes greatly to the left. The cause of this phenomenon is the protective sheet
It is considered that the unevenness of 13 or the unevenness of the FRP tape 12 itself is large.

When the position of the FRP tape 12 changes greatly to the left and right, the FRP tape 12
The position of the FRP tape 12 cannot be completely corrected only by the position correcting motion by rotating the roll group 10 for correcting the position in the width direction of the roll. It becomes impossible to keep the clearance between the FRP tapes 12 laid on top of each other below a predetermined amount.

Therefore, sandwiching the FRP tape 12 between the feed rolls 16 and 14 for feeding the FRP tape 12 causes the above-mentioned problems and is not a good method.

[Object of the Invention]

The object of the present invention is that a plastic film is not adhered and only a protective sheet is adhered to one side of the adhesive FRP tape without sticking to the component parts, and the FRP tape is fed out. An object of the present invention is to provide a novel automatic FRP tape sticking device which does not adopt a mechanism of sandwiching FRP tape between rolls as a mechanism.

[Means for Solving the Problems]

First of all, as a means for solving the problem, it was decided not to use a pinch feed roll. Instead FR
When the P tape is unwound from the supply reel, the FRP tape is sandwiched between the sticking roll or sticking shoe and the specified mold, so this automatic sticking device sandwiches the FRP tape between the mold. If you move it in a crowded state, the FRP tape will be stuck to the mold, so you can move the FRP tape by moving the automatic sticking device.
The tape has a structure in which it is unwound from the supply reel by itself. At this time, the rotation of the supply reel itself was braked and a force was applied to the FRP tape by a dancer roll so that proper tension was applied to the FRP tape.

As a second means, the components of the automatic sticking device are directly FR
The PRP tape was prevented from contacting and sticking to facilitate the relative movement between the FRP tape and the automatic sticking device.

Example of Invention

FIG. 1 shows an embodiment of the present invention. 60 is FR according to this embodiment
The whole of the automatic sticking apparatus of the P tape 41 is shown. Reference numeral 40 is a supply reel in which a FRP tape 41 having a protective sheet 42 attached to one side is wound up. When unwinding the FRP tape 41 and the protective sheet 42 from the supply reel 40 while unwinding the supply reel 40, the supply reel 40 rotates, but this rotation applies a brake of an appropriate value.

The fed-out FRP tape 41 passes through the dancer roll 43, reaches the position correction roll 44, bends, and rolls downward to be a cutting device.
After passing through the guide 46 and the guide 47, it is pressed and stuck on the surface of the mold 53 by the sticking roll 48 part. The remaining protective sheet 42 passes through the pinch roll 49 and the guide 50, and the protective sheet take-up reel.
Wound up in 51.

The dancer roll 43 is swingable in the direction of the arrow, applies a load to the FRP tape 41 and the protective sheet 42 to adjust the tension, and at the same time, the FRP tape 41 in the path over each of the above components of the automatic sticking apparatus. Absorb the slack. Reference numeral 45 is a detection device for detecting the position of the edge of the FRP tape 41, and the axis of the position correction roll 44 is rotated by a drive device (not shown) in response to a signal generated by the detection device 45.

By this rotation movement, the reel 40 is unwound from the supply reel 40.
Even if the position of the FRP tape 41 changes in the width direction, the position of the FRP tape 41 after the position correction roll 44 is corrected in the width direction and travels at a certain position. The cutting device 46 does not cut the protective sheet 42 and cuts only the FRP tape 41 into a predetermined length programmed in advance. Since the sticking roll 48 is pressed downward by the air cylinder 52 and pressed onto the surface of the mold 53, the protective sheet 42 and the FRP tape 41 are pressed to the mold 53 by the sticking roll 48, and the FRP tape 41 is It is attached.

The sticking roll 48 may be a warp-shaped shoe instead of a roll, and the air cylinder 52 may be a hydraulic cylinder or a spring. The above-mentioned components are integrally mounted on the frame 61.

When the FRP tape 41 is attached, the automatic attaching device 60 attaches the FRP tape 41 while moving the mold 53 leftward. The movement stops after moving a predetermined distance, and then it rises and the adhesive roll 48 moves to the mold 53.
And then retreat to the right and shift by a width of the FRP tape 41 at a right angle to the paper surface of FIG. 1 and then descend (ascending / descending drive device, forward / backward drive device are not shown). Enter the sticking operation. Thereafter, this movement is repeated and the FRP tape 41 is stuck and laid in a predetermined number of rows. When the automatic sticking device 60 rises and the sticking roll 48 is separated from the mold 53, the pinch roll 49 is provided to prevent the FRP tape 41 stuck to the protective sheet 42 from moving in the longitudinal direction of the running path. Fix the position by sandwiching the protective sheet 42.

As described above, in the automatic sticking device 60, the dancer roll 43, the position correction roll 44, and the guide 47 all contact only the protective sheet 41 and do not directly contact the adhesive FRP tape 41. The FRP tape 41 runs smoothly without any trouble. With such a configuration, the pinch-type feed roll shown in the prior art is not used, so that the FRP tape 41 can be automatically attached without a large lateral displacement in the feed load portion.

〔The invention's effect〕

In the automatic sticking of FRP tape, by adopting the structure that does not use the feed roll that sandwiches the FRP tape between the rubber roll and the metal roll in the tape path from the supply tape reel to the sticking roll, In
It has become possible to greatly reduce the fluctuations in the position of the FRP tape in the width direction, eliminate the adhesiveness between the FRP tape and the device components, and facilitate the feeding of the FRP tape.
