2. Description of the Related Art Turret-type continuous winders typically
The bobbins mounted on the turret are sequentially moved to the winding position for winding the filament by rotating the turret, and the filament is wound from one bobbin of the plurality of bobbins to another bobbin to form the filament. It is configured to be continuously wound.

In the continuous winding machine of this type, in order to enable the wire body to be wound on the bobbin at the winding position in a good condition, the winding position is set to the wire body to be wound. It is preferably located at a position facing the guide member so as to approach the guide member.

[0004]

However, the winding position facing the guide member has a turret and various rotary parts mounted on the turret between the winding position and the position accessible by the operator. Therefore, when fixing the first winding start end of the filament body to the bobbin to be wound up first and starting winding, the worker extends the body over the rotating parts on the turret and fixes the winding start end. I have to do some work. For this reason, the worker's body touches the waiting bobbin, or the worker's hand touches the rotating bobbin.
It was not possible to safely perform the work of fixing the filament to the bobbin at the beginning of winding.

The object of the present invention is to avoid the above-mentioned drawbacks, to secure the first winding start end of the filamentous body safely, and to wind up the filamentous body satisfactorily thereafter. An object of the present invention is to provide a method for continuously winding a filament.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention uses a turret to rotate a plurality of bobbins mounted on a turret to a winding position facing a guide member of a filament body to be wound. In a linear filament continuous winding method, the filament element is continuously moved, and the filament element is wound from one bobbin of the plurality of bobbins to another bobbin to continuously wind the filament element,
When the first winding start end of the filament is fixed to one bobbin and winding is started, this one bobbin is retracted from the winding position and held at a work starting position accessible by the operator. The winding start end is processed while the winding start is performed, and then one bobbin is returned to the winding position or the next bobbin is moved to the winding position and thereafter the winding is continuously performed. An object of the present invention is to provide a method for continuously winding a filament.

[0007]

As described above, when the first winding start end of the filament is fixed to one bobbin and the winding is started, the one bobbin is retracted from the winding position to be accessed by the operator. When the winding start end is processed and the winding start is performed while the work start position is maintained, the operator does not have to extend the body to one bobbin to which the first winding start end should be fixed, Can be safely processed, and after fixing the first winding start end and starting normal winding,
This one bobbin can be returned to the winding position facing the guide member, or the linear body can be wound on the next bobbin to wind the linear body in a good state.

Next, the continuous winding method of the present invention will be described in detail with reference to FIG.
1, is supplied from the supply bobbin 46 to the continuous winder 10 via the guide roller 48 and the dancer device 50, for example. The dancer device 50 has a dancer roll 52 that swings between the positions shown by the upper dotted line and the lower dotted line in FIG. In addition, the winder body 14 of the continuous winder 10
A pulley-shaped guide member 54 for guiding the filament 1 is provided inside the dancer device 50 on the outlet side. 1, reference numeral 56 indicates a control panel and reference numeral 58 indicates an operation panel.

First, when the first winding start end 1a of the filament 1 is fixed to one bobbin 18 of the continuous winding machine 10 to start winding, as shown in FIG. The bobbin 18 is positioned to the work start position in front of which the operator 60 can access the bobbin 18 or 18 ', and the turret 16 has the projection 26 of the positioning cylinder 28 of the positioning means 24 in the positioning groove 22B. Engage and hold at the work start position. In this state, as shown in FIG. 7, the winding start end 1 a of the filament 1 is attached to the waste winding portion 4 of the bobbin 18.
It is hooked and fixed to the second claw 44, and in this state, the winding machine main body 14 is driven to start winding.

Thereafter, as shown in FIG. 1, the positioning means 24 is released, and the bobbin 18 which has been wound with the winding start end 1a of the filament 1 being fixed is advanced to the winding position facing the guide member 54. The turret 16 is rotated so that the winding position is such that the protrusion 26 of the positioning means 24 is engaged and held in the positioning groove 22A. During this winding, the winder main body 14 traverses between the bobbin solid line position and the bobbin dotted line position of FIG. 2 in a direction parallel to the axis of the bobbin 18 by a traverse mechanism (not shown), and the filament body 1 moves. Winded evenly on top. In addition, since the bobbin 18 is located close to the guide member 54 during the normal winding, the filament 1 is wound around the bobbin 18 in a good condition.

When the wire body 1 is fully wound on the bobbin 18, a full winding signal gives a command to the turret driving means to rotate the turret 16 by 180 degrees in the direction of the arrow in FIG.
6, the bobbin 18 moves so that the bobbin 18 is at the bobbin take-out position and the bobbin 18 ′ is at the take-up position, and this position is positioned by the positioning means 24 in the positioning groove 22′A.
The projection 26 of is engaged and held.

In this case, the linear member 1 is, as shown in FIG. 8, a first wire rod 32 on the bobbin 18 side of the wire moving means 30 and a second wire rod 34 on the bobbin 18 'side. Pass between and. After that, as shown in FIG. 9, the first wire pulling rod 32 is displaced toward the useless winding portion 42 side of the bobbin 18 by the wire pulling cylinder 38, and the linear body 1 is bitten into the biting claw 44 thereof. After that, the filament 1 is wound around the dead winding portion 42 of the bobbin 18.

Next, as shown in FIG. 10, the second wire pulling rod 34 is displaced toward the dead winding portion 42 'side of the bobbin 18', and the filament body 1 is engaged with the bobbin 18 'which has already rotated. Pawl 4
The linear body 1 is fixed to the bobbin 18 'by being bitten into 4'.
Therefore, as shown in FIG. 11, the linear body 1 is drawn downward along the line-placing rod 34 with the rotation of the biting claw 44 ′, and by the cutter 40 provided below the line-placing rod 34. Be disconnected. Therefore, the linear body 1 on the bobbin 18 and the waste winding portion 42 is separated from the linear body 1 to be subsequently wound on the bobbin 18 '.

Therefore, thereafter, the rotation of the bobbin 18 is stopped and the filament 1 is continuously wound around the bobbin 18 '. on the other hand,
The fully wound bobbin 18 is pulled out from the support shaft 20, and a new empty bobbin 18 is supported by the support shaft 20 to stand by for the next winding. The bobbin 18 is replaced on the side surface of the winder body 14. In this case, the winder body 1
4 moves in and out on the side surface by the traverser mechanism, but since this moving in and out is done slowly, there is no problem in replacing the bobbin 18.

When the bobbin 18 is replaced, the linear body portion wound from the bobbin 18 to the waste winding portion 42 is unwound. The waste winding portion 42 moves the linear body 1 from the bobbin 18 to the bobbin 1 after the predetermined amount of the linear body 1 is wound around the bobbin 18.
When it is moved to 8 ', the tension of the linear body increases due to the impact of cutting the cutter, which may damage the already wound linear body of the bobbin 18,
There is a risk that it will bite between the already-wound linear bodies and hinder the smooth feeding of the linear bodies in the subsequent process or wind up a defective conductor, so until the linear body 1 is moved from the bobbin 18 to 18 '. It is provided in order to prevent the extra linear body 1 from being caught in the bobbin 18 between them, so that the linear body 1 on the waste winding portion 42 is cut off when the fully wound bobbin 18 is removed. It will be.

In the above embodiment, the bobbin 18 is fixed after the first winding start end 1a of the filament 1 is fixed to the bobbin 18.
1 was moved to the normal winding position shown in FIG. 1 for normal winding, but this bobbin 18 was moved to the bobbin taking-out position shown in FIG. 3 to perform the same operation as the rewinding of the bobbin after full winding. Then, the filamentous body 1 may be wound onto the next bobbin 18 ', and the usual winding operation thereafter may be performed.

[0022]

As described above, according to the present invention, the bobbin for fixing the first winding start end of the filament is retracted from the normal winding position and the operator can access the work starting position. Since the winding start end is processed while holding the winding start end, the operator does not have to extend the body to the normal winding position of the bobbin, which is the back of the winder, and the first winding start end is processed. Can be carried out safely, and after this initial winding start end is fixed and normal winding is started, the bobbin is returned to the winding position facing the guide member for guiding the linear body, or Since the filament is wound on the next bobbin and wound up, the filament can be wound in a good condition.
