[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous tape winding method and apparatus for continuously winding a tape on a running wire, and more particularly, to a method of providing a tape outside and inside coaxially with the wire. The main tape supply means and the auxiliary tape supply means are provided, and the tape is usually wound around the wire from the tape pad on the main tape supply means, and the tape pad on the main tape supply means is consumed. Previously, the tape from the tape pad on the main tape feeding means was temporarily transferred to the auxiliary tape feeding means, and while the tape was wound around the wire from the auxiliary tape feeding means, The present invention relates to an improvement in a method and an apparatus for continuously winding a tape while supplying a tape by connecting an external tape supply source to the tape.

[0002]

2. Description of the Related Art A tape to be wound around a wire is temporarily transferred from a main tape feeding means to an auxiliary tape feeding means, and the main tape is fed from the auxiliary tape feeding means while the tape is wound on the wire. A technique for replenishing the feeding means with a tape and continuously winding the tape on a wire has been proposed by the present inventor (see Japanese Patent Publication No. 48-18018).

In this prior art, the main tape feeding means is composed of an outer disk having a plurality of outer rollers, and the auxiliary tape feeding means is composed of an inner disk having a plurality of inner rollers, and runs on the outer disk and the inner disk. The wire always rotates at a constant speed around the wire, and the tape is wound around the wire from the tape pad around the outer roller on the outer disk.However, before the tape on the outer disk is exhausted, While the tape on the outer disk is temporarily moved around the inner roller and the tape is fed out from the inner disk and wound around the wire, the rotation of the outer disk is stopped, and the outer disk remains on the outer disk. After the supply tape is connected to the end of the tape that is It is supplemented with tape on another disk. Therefore, according to this technique, the tape can be continuously wound around the wire while the tape is always supplied onto the outer disk, which is advantageous.

However, in this prior art, the main tape feeding means and the auxiliary tape feeding means are composed of a plurality of rollers provided on the outer disk and the inner disk at intervals in the circumferential direction. Since the tape laminated around the outer roller and the inner roller has a polygonal shape corresponding to the number of rollers, when the tape is sent out by the rotation of the roller, the tape receives the deformation resistance at the acute angle portion of the polygon, and the tape is in contact with the roller. There is a risk that the tape may fail to be fed at a speed equal to the peripheral speed of the roller due to slippage between the rollers.

In this prior art, each roller of the main tape feeding means or the auxiliary tape feeding means rotates at a speed commensurate with the consumption of the tape, but the tape slips with the rollers. If the rotation speed of the rollers does not accurately follow the consumption of the tape, the tape may be loosened or tightened when wound around the wire, and the tape may not be wound with an appropriate tension. was there.

As shown in FIG. 1, the rotation of the outer disk 22 of the main tape feeding means 26 is stopped, and the tape 2 is fed to the auxiliary tape feeding means 32 more than its consumption regardless of the stop of the outer disk 22. As described above, the speed of the drive belt conveyor 42A of the main tape feeding means 26 is increased. The fixer disk 18 of the tape holding means 20 is provided with a main tape feeding means 26.
Regardless of the stop of the outer disk 22, the tape pad 2 </ b> A is supplied from the outer disk 22 by the auxiliary tape feeding means 32.
In order to be able to smoothly move to the inner disk 28, the rotation is performed at a speed commensurate with the amount including the amount of movement and the amount of consumption.

Accordingly, the tape 2 is transferred from the tape pad 2A in the main tape feeding means 26 onto the driving belt conveyor 42B of the auxiliary tape feeding means 32, and at the same time, the driving belt conveyor 42B matches the consumption of the tape 2. The tape 2 is driven at a predetermined speed to continuously wind the tape 2 around the wire 1.

As shown in FIG. 12, the main tape feeding means 2
When the amount of the tape 2 corresponding to the time required for connecting the external tape supply source 2B to the tape 2 remaining in the tape 6 moves to the auxiliary tape feeding means 32, the tape connectable time detector 144 connects the tape. The signal Sc is input to the control means 140, and the control means 140 stops the rotation of the fixer disk 18 of the tape holding means 20, and at the same time, stops the driving of the drive belt conveyor 42A of the main tape feeding means 26. The external tape supply source 2B is attached to the extra length 2a of the tape extending outside the clamp 36 of the holding means 20.
Can be connected.

As shown in FIG. 12, during this time, the tape 2
From the auxiliary tape feeding means 32 to the inner disk 2
The rotation of the tape 8 and the driving of the drive belt conveyor 42B supply the tape 2 to the tape winding section 16 and continue the winding of the tape 2.

Then, as shown in FIG. 13, the clamp 36 of the tape holding means 20 is opened, and the outer disk 22 of the main tape feeding means 26 is moved to the auxiliary tape feeding means 32 while the fixer disk 18 is stopped. And is wound around the drive belt conveyor 42A of the main tape feeding means 26 at a rotation speed faster than that of the inner disk 28. This is because the main tape feeding means 26 and the auxiliary tape feeding means 32 do not have the tape 2 at first.
This is the same as the state in which a certain amount of tape 2 is wound around 2, and at that time, the subsequent operation is described with reference to FIG.

The main tape feeding means 26 and the auxiliary tape feeding means 32 are provided on the outer disk 22 with the outer rollers 24.
The tape 2 is fed not by the rotation of the inner roller 30 nor by the rotation of the inner roller 30 on the inner disk 28, but by the driving of the drive belt conveyors 42A and 42B wrapped around the tape. The drive belt conveyors 42A and 42B
As shown in (A), the outer disk 22 of the main tape feeding means 26 and the inner disk 28 of the auxiliary tape feeding means 32 are deformed in a circular shape by the action of the centrifugal force at the time of rotation. The belt is fed at a predetermined speed without frictional engagement with the drive belt conveyors 42A and 42B.

If the tape 2 is directly contacted with the outer roller 24 or the inner roller 30 and fed by its own rotation, as in the prior art shown in FIG.
Move linearly between adjacent rollers to form a polygonal shape, which tends to generate deformation resistance at the acute angle portion of the polygonal shape of the tape 2, and between the tape 2 and the rollers 24, 30. Although there is a possibility that slippage occurs and the feeding of the tape 2 does not match the consumption amount, the driving belt conveyor 42A,
In the case of 42B, this can be avoided and the tape 2 can be wrapped well.

The tape 2 fed from the main tape feeding means 26 or the auxiliary tape feeding means 32 is supplied to the first direction changing roller 128 of the tape transfer means 126 as shown in FIGS. In parallel with the running direction of the wire 1, the wire 1 moves in the same direction as the running direction of the wire 1, and passes through the second direction changing roller 130 to be the tape tension setting means 94 on the wound disk 92 of the tape wound portion 16. Capsta 13
2 and between the pinch roller 134, is sent to the wire 1 via the guide roller 138, the wound disk 92
As shown in FIG. 3, since the tape 2 rotates around the wire 1, the tape 2 is wound around the wire 1.

As described above, when the tape 2 is wound around the wire 1 via the tape tension setting means 94 independent of the main tape feeding means 26 and the auxiliary tape feeding means 32, the feeding speed of the tape 2 is increased. Even if the tape 2 does not accurately follow the consumption of the tape, the tape 2 is not loosened or tightened when the tape 2 is wound around the wire 1, and the tape 2 is wound around the wire 1 with an appropriate tension. Can be.

The positions of the dancer rollers 152A and 152B with which the tape 2 contacts and pass are detected by the position detector 158 as described above, and the output thereof is controlled by the control means 1.
40, the control means 140 controls the dancer roller 15
Since the speeds of the drive belt conveyors 42A and 42B are controlled so that 2A and 152B are at predetermined intermediate positions, the feeding of the tape 2 is switched between the main tape feeding means 26 and the auxiliary tape feeding means 32. At times, correction is made so that the feeding of the tape 2 is aligned.

When the tape 2 is wound around the wire 1 in the opposite direction, as shown in FIG.
0, main tape feeding means 26 and auxiliary tape feeding means 32
The tapes 18, 22, and 28 are rotated in the opposite directions, and the drive conveyor belts 42A and 42B are also rotated in the opposite directions. Further, as shown in FIG. From the source 2B, the position of the clamp 36 is reversed and the tape is supplied from the opposite direction.
