Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for winding a filament such as an electric wire cable into a filament.

In order to orderly wind the filament around the drum, the winding device is provided with a traverse means, in addition to a means for imparting rotation to the winding drum, to sequentially move the position of the filament with respect to the winding drum.

In this case, when the filament approaches the flange of the winding drum, this is detected and the direction of movement of the traverser is reversed. In many cases, the means for causing the traverser to perform a reversal operation is to place a switch, such as a limit switch, along the screw shaft on which the traverser is locked, and to operate this switch as the traverser moves. In this method, when the winding width of the drum changes, the position of the switch must be adjusted in accordance with the change.

In view of the above, the present invention has been developed to allow the traverser to easily perform the reversing operation without being affected by the winding width of the drum.
A detector such as a limit switch is attached to the traverser, and a member for controlling the operation of the detector is provided to the drum mounting section.

This will be explained with reference to the accompanying drawings. As shown in the figure, the winding device is supported by stands or arms 31 and 32, and is driven by a motor 1 to rotate a mounted winding drum D. A screw shaft 6 arranged parallel to the feeding shaft 2 and connected to the motor 4 via a direction switching device 5, and a traverser 7 that is locked to this shaft and moves left and right as the shaft 6 rotates. It consists of limit switches 81, 82 attached to the arm 71 of this traverser, and members 9, 10 having rolls 91, 101 attached to the stands or arms 31, 32 and in contact with the outer surface of the collar of the drum D. .

Thus, the members 9 and 10 include a bar 92 and a bar 92 located on the passages of the limit switches 81 and 82, respectively.
102, and is configured such that the rolls 91, 101 are always in contact with the brim of the drum D by cylinders 93, 103, respectively, when the drums are mounted.

In such a configuration, winding of the filament W is started by fixing the tip of the filament W to the drum D and then driving the motors 1 and 4.

As the winding progresses and the filament W approaches one of the flanges of the drum D, the traverser 7 is also moving in that direction, so the movable part of the limit switch 81 (or 82) , the bar 92 (or 102), and the detection signal actuates the direction changing device 5 to operate the screw shaft 6 and move the traverser 7 in the opposite direction.

During this reversal of the traverser 7, the filamentary body W is wound up at the flange of the drum D, but since it moves as the traverser 7 reverses, it then develops as a wound layer. At this time, bar 92 (or 102)
If the circumferential surface of the traverser 7 is slightly inside the inner surface of the flange as shown in the figure, the traverser 7 will stop prior to reversing, and
Even if the striatum W tries to roll up along the flange, a lateral force will act on the striatum W, so
The striatum W will be shifted laterally without overlapping more than necessary.

If the striatum W approaches the other flange again, the limit switch 82 (or 81)
is detected by the bar 102 (or 92), and the traverser 7 is moved in the opposite direction again. As a result, new winding layers are formed one after another, and finally, the length is reached, and the supply of the filament body W is cut off, and the drum D
will be replaced.

If at least one of the members 9 and 10 is configured to move together with the movement of the shaft 2 when replacing the drum D, the members 9 and 10 will not become an obstacle when replacing the drum. After installing a new drum, even if there is a change in the winding width of the new drum, the bars 92, 10 can be fixed by bringing the rolls 91, 101 into contact with the flanges of the drum.
Position 2 is automatically set to a position that matches the winding width of the drum, so limit switch 8
The next winding can be opened and stopped without special adjustment of the positions 1 and 82.

Although this example uses contact type limit switches as the detectors 81 and 82, a non-contact type phototube switch can also be used instead of the limit switches. In that case, bars 92, 102
Although it is necessary to attach reflective tape or the like to the surface of the winding drum, it is much more economical than attaching reflective tape or the like to the inside of the flange of each winding drum.

As is clear from the above, in this invention, the detector is attached to the traverser side, and the member for activating it is attached to the drum mounting side. Even if the winding width of the drum changes, the next winding operation can be started without any special adjustment operation by just making contact with the drum. This method has the advantage of being able to prevent the phenomenon of winding, and greatly contributes to the automation of winding operations.
