Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a so-called alignment winding device, which is a device for orderly winding wire bodies such as electric wire cables onto a drum.

As this type of winding device, a so-called winding point tracking type winding device that detects a winding point and moves a traverser is known.

According to such a winding device, it is possible to automatically wind the film in alignment, but sometimes the winding may occur in an irregular manner. This is because the delay in the position of the traverser relative to the winding point changes depending on the winding tension, dimensions, material, etc. of the filament, and when the filament comes to the flange of the winding drum, the traverser moves along the flange. This is caused by riding on multiple layers.

To solve this problem, it may be possible to detect when the position of the traverser approaches the drum flange and cause the traverser to perform a reversing operation and other operations, and various proposals have been made for this purpose. This would make it mechanically complex.

The present invention has been developed in consideration of this point, and is characterized in that a pair of wire running prevention means is installed on the traverser side of the portion where the winding drum is mounted.

This will be explained with reference to the accompanying drawings. The outline of the apparatus is as shown in FIG. 1. The device is the striatum W
It consists of a traverser 1 that guides the winding drum B, a shaft 5 that supports and drives the winding drum B, and means 9 that prevents the filament W from riding up.

The traverser 1 is engaged with a screw 3 driven by a motor 4, and can be moved left and right parallel to the shaft 5 by rotation of the screw 3. Traverser 1 lag angle detection means 2
is provided, and the traverser 1 is controlled by a signal from this means 2 so that it can follow the winding point.

Drum B that winds up the filamentous body W that has passed through the traverser 1
A shaft 5 supporting the drum is driven by a motor 7 and is moved in the axial direction as appropriate to enable attachment and detachment of the drum.

The riding prevention means 8 consists of a pair of elongated rolls 9 rotatably attached to bosses 10, respectively. The rolls 9 are set so that their circumferential surfaces are within about half the diameter d of the filament W from the inner surface of each collar of the drum B. The distance that the circumferential surface of the roll goes inward from the inner surface of the collar is the distance between the striatum W
It varies depending on the material, tension, direction of twist, etc. =
Since it is in the range of 1/4 to 2d, it is appropriately selected within this range.

Therefore, it is desirable that each roll 9 is movably attached to the boss.

The bosses 10 are respectively attached to actuators 11 attached to a stand 6 that supports the shaft 5, and rolls 12 are also rotatably attached to the bosses 10, respectively. This roll 12 is pressurized by the operation of the cutter 11 so as to come into contact with the outer surface of the flange of the drum B, so that the distance is always kept constant with respect to the drum of the same size.

In such a configuration, winding is performed by fixing the tip of the filament W to the bobbin B supported by the shaft 5 via the traverser 1, and driving the motors 4 and 7.

However, when the winding progresses and the filament body W reaches one collar, the traverser 1 enters a resting and reversing operation. During this time, as shown in FIG. , a lateral force acts on the striatum W and the striatum W is shifted laterally, so that a double,
There will be no triple increase.

At this time, since the traverser 1 is in the reversing operation, the filament W is wound up as a new layer.

However, when the striatum W reaches the other tsuba,
Roll 9 performs the same function as one of the rolls 9.

Therefore, by reciprocating the traverser 1 from side to side, each layer can be wound up in an orderly manner. The fact that the roll 12 attached to the roll 9 is in contact with the drum B is a result of imparting vibrations to the filamentary body W due to the precision of the flange surface of the drum B or the misalignment of the axis of the drum B. Therefore, it is possible to help prevent the filamentous body W from riding up on the flange portion. Of course, the presence of this roll 12 is also effective in keeping the position of the roll 9 substantially constant without being affected by fluctuations in the outer width of the drum B.

As described above, according to the present invention, it is possible to prevent the flange from riding up during winding using a simple mechanism, and it is extremely effective in performing aligned winding.
