The fiber bundle 11 that is squeezed with excess resin by the squeeze member 12 and is fed out passes through the inside of the guide tube 21 and is led out from the guide tip 22. At this time, the rotation speed of the rotating body 23 and the drawing speed of the drawing machine 5 are kept constant. The pitch of winding and winding the tape 13 can be changed by changing the rotation speed of the rotating body 23.

Tape 1 wound on tape bobbin 27
3 is applied with a constant tension from the guide pieces 43a and 43b of the tape shaker 38 through the support plate 37 of the rotating body 23, the tape tension device 46 provided on the floating plate 36, and the tape winding and winding guide device 40. And is wound around the fiber bundle 11 impregnated with the uncured resin at a constant angle. After that, the fiber bundle 11 is cured by the heating mold device 4 to be FRP.
It becomes the rod 14.

The tape winding operation at this time is performed by rotating the rotating body 23 in the winding direction of the tape 13 by the first motor 31. At this time, the tape bobbin 27 is rotationally controlled in the winding direction by the second motor 33 with a difference in the number of revolutions of the tape 13 with respect to the rotation groove of the rotor 23.

By the rotation of the rotating body 23, the tape 13 is wound around the tape 13 and the torque limiter 4 of the winding guide device 40.
It is fed out while being braked by the roller No. 5, and the tension of the tape 13 between the torque limiter 45 and the tape shaker 38 is maintained by the tape tensioning device 46. At this time, the tension force of the tape 13 by the guide member in the apparatus is biased by the spring 52 to the tip side of the apparatus by the spring 52, whereby the tape tension detection rollers 55a, 55.
It is obtained by the protruding movement of b.

Therefore, when the tape 13 is fed out from the tape bobbin 27 in a large amount with respect to the winding amount around the fiber bundle 11, the tension in the tape tensioning device 46 becomes small,
The floating plate 36 moves toward the tip side by the spring 52, and the position detection plate 48 fixed to the floating plate 36 changes from the neutral position a ₀ to the proximity position a ₁ with respect to the displacement sensor 49.

Conversely, the tape 1 from the tape bobbin 27
When the feeding amount of 3 is small, the tension in the tape tension device 46 becomes large, and the floating plate 36 moves to the spring 5
The position detection plate 48 moves from the neutral position a ₀ to the separated position a ₂ with respect to the displacement sensor 49 by moving toward the base end side against ₂ .

Each position a ₀ , a ₁ , of the position detecting plate 48
a ₂ is detected by the displacement sensor 49, each detection signal is output to the sequencers 63a and 63b, and the position detection plate 48
At the position a ₁ , the rotational speed of the tape bobbin 27 is relatively reduced, and at the position a ₂ , the tape bobbin 27 is rotated.
The rotation speed of the tape bobbin 27 is controlled so that the position detection plate 48 returns to the neutral position a ₀ by relatively increasing the rotation speed thereof. As a result, the tape 13 is delivered from the tape bobbin by a fixed amount.

As described above, the rotation of the tape bobbin 27 is controlled by the displacement sensor 49 detecting the position of the position detecting plate 48, and FIG.
It becomes as shown in.

That is, when the diameter of the tape bobbin 27 becomes small (1) within the time required for forming the FRP rod, the amount of the tape 13 fed out per one rotation of the tape bobbin 27 becomes small (2). Even at this time, the amount used with respect to the amount of the fed tape 13 does not change (3). The length of the tape 13 wound around the tape tension device 46 is shortened (4). The floating plate 36 of the tape tensioning device 46 moves to the base end side against the spring 52, and the position detecting plate 48 moves to the a ₂ side (5).
The movement of 8 is detected by the detection sensor 49 (6), and this detection signal is sent to the sequencer 63b of the second motor 33 (7), and the sequencer 63b speeds up the rotation of the tape bobbin 27 (8).

When the tape bobbin 27 rotates faster, the amount of the tape 13 fed out from the tape bobbin 27 increases, so that the floating plate 36 is pushed by the spring 52 and the position detecting plate 4 is moved.
8 is returned to its original position a ₀ (9). Position detection plate 48
It is detected by the position sensor 49 (10), the signal is sent to the sequencer 63b of the second motor 33 (11), increase in the rotational speed of the tape bobbin 27 to stop but returned to the original position a ₀ (12).

The above operation is repeated from (1) to (12). If the tape bobbin 27 is overrun due to a mechanical cause when the increase in the rotation speed of the tape bobbin 27 is stopped, the position sensor delays the tape bobbin 27 so as to return the position of the disk to a ₀ .

As described above, the winding diameter of the tape 13 of the tape bobbin 27 is decreased by the winding of the tape 13, but the deviation of the rotation moment of the tape bobbin 27 with respect to the rotation axis does not occur. Therefore, tape bobbin 2
The rotation speed of 7 can be increased and used. Further, even if the tape bobbin 27 is used with a large diameter, it can be used for a long length because there is no deviation in the rotational moment.

The tape 13 is replenished to the tape bobbin 27 by rotating only the support cylinder 26 and winding it from the outside into the tape bobbin 27 which rotates integrally with the support cylinder 26 via the tape winding guide device 60.

The tape winding and winding device 1a, 1
In the explanation of the action of b, the example used for winding the tape has been shown, but it can be used in the same way for winding. However, when used for winding the tape, the rotating body 23 and the support cylinder 26 are rotated in the opposite direction to those for winding the tape. And the tape 13 that has been wound up
Is taken out through the tape winding guide device 60.

In the device 1b used for winding the tape, the tape 13 is peeled off from the FRP rod 14 at a fixed winding position, and the tape bobbin 2 passes through the guide portion as in the tape winding and winding guide device 40.
Take up to 7. At this time, the rotation speed of the tape bobbin 27 is controlled by using the tension in the guide portion in the apparatus as a parameter so that the tape 13 does not sag. At this time, the basic rotation speed of the rotating body 23 (tape bobbin 27) is synchronized with both the winding and winding devices 1a and 1b, and the pulling machine 5 is also synchronized with the stop and the start of molding. It is also possible to continuously change the winding pitch of the tape 13 and the parameters of the speed by an external control device.

Next, specific examples of winding the tape 13 by the tape winding and winding device 1a for winding the tape will be shown as Examples (1) and (2).

At the time of molding, no vibration occurs even at this rotation speed,
In addition, the rotation failure due to the weight reduction or weight increase of the tape bobbin 27 did not occur. Further, the rotation at the time of start-up was smooth, and the tape bobbin 27 of the tape winding and winding device 1b for winding the tape was synchronized even though the tape bobbin 27 was empty, and the rotation of the tape bobbin due to the weight change of the tape bobbin did not change.

At the time of molding, no vibration occurs even at this rotation speed,
In addition, the rotation failure due to the weight reduction or weight increase of the tape bobbin 27 did not occur. Further, the rotation at the time of start-up was smooth, and the tape bobbin 27 of the tape winding and winding device 1b for winding the tape was synchronized even though the tape bobbin 27 was empty, and the rotation of the tape bobbin due to the weight change of the tape bobbin did not change. During molding, the speed was reduced to 20 cm / min to check the quality of the molded product due to the change in molding speed, but there was no problem in following the rotation when the speed decreased, and the tape winding and rotation speed was controlled by changing the molding speed. It was being appreciated. As a result of observing the molded product at this time, no pitch abnormality was observed in the winding and winding of the tape at the time of low speed molding, and it was confirmed that there was no problem in winding and winding of the tape. After that, when the molding speed was increased to 2 m / min, the rotation followed up to 250 r, p, m, and there was no defect in the molded product as in the case where the molding speed was reduced.

Example 3. Two tape winding and winding devices 1a, 1a for winding a tape, which incorporates a tape bobbin having a width of 4 mm and a thickness of 0.25 mm and having a thickness of 8800 mm, are arranged side by side on the line, and two corresponding winding units are arranged. The devices 1b and 1b for taking out are arrange | positioned on both sides of the heating-die apparatus 4.

Then, the tape 13 is molded at an initial speed of 20 cm / min for winding, and the tape winding device 1a, 1b rotating in opposite directions is used to measure the diameter 1
2 tapes 13 on a 0 mm FRP rod with pitch 20
When the tape reaches the winding device 1b, 1b, the tape 13 after curing is connected to each tape bobbin of the winding device 1b, 1b, and then the molding speed is set to 2 m. / Min.

The time required to mold a molding amount of 2500 mm was 20 hours and 50 minutes without any preparation time. At this time, the number of rotations of the rotating body 23 of the tape winding and winding device 1a for tape winding is 100r, p, m, and the number of rotations of the rotating body 23 of the tape winding device 1b is 100 ± 25r, p, m.

At the time of molding, no vibration occurs even at this rotation speed,
In addition, the rotation failure due to the weight reduction or weight increase of the tape bobbin 27 did not occur. In addition, the follow-up of the rotation from low speed (20 cm / min) to high speed (2 m / min) at the time of starting is smooth, and the tape bobbin 27 of the tape winding and winding device 1b for winding the tape is synchronized even though it is empty. There was no change in rotation due to the change in weight of the tape bobbin.

When the molded product was observed, it was confirmed that there was no abnormality in the pitch in the winding and rewinding of the tape at the time of shifting from the low speed molding to the high speed molding, and no trouble occurred in the tape winding and rewinding machine.

In the embodiment of the present invention, the displacement sensor 49 detects the position of the position detecting plate 48 that moves in the axial direction due to the change in the feeding tension of the tape 13, as a means for detecting the amount of feeding of the tape 13, and the detection is performed. Although an example in which the rotation speed of the tape bobbin 27 is controlled by a signal is shown, the means for detecting the amount of the tape 13 delivered is not limited to this, and the following means may be used.

That is, the feeding speed of the tape 13 is measured by a non-contact type laser speed meter, and when the speed becomes faster than the speed set to stay within a constant value, the rotation speed of the tape bobbin 27 is slowed down. In the opposite case, the rotation speed of the tape bobbin 27 is increased.

Further, the tension and load of the contact type spring are directly measured, and the rotation speed of the tape bobbin 27 is controlled according to the change of the load at this time.

Further, the tape 13 is wound around, and a tachometer is attached to a roller which rotates in accordance with the unwinding of the tape 13 to measure the unwinding speed of the tape 13.

The detection means in each of these embodiments is measured alone or in combination, and is transmitted to the control device wirelessly or by wire.
