Winding machine

State of the art

The invention relates to a winding machine, in particular to a device for laying threads, cords or tapes on a winding body of the winding machine (reel, reel).

In known devices of this type, the laying of the threads is carried out, for example, via continuously operating crank loops, elliptical gears or laying rollers.

These known devices have several disadvantages:

l.The end product of the roll becomes thicker at the turning points according to the movement of the thread guide; this interferes with the further processing of the roll.

2.The path of the thread guide is constant or can only be changed with considerable mechanical effort. Depending on the material and dyeing device for the material to be wound, the winding length must be changed.

3 .The thread guide cannot be automatically moved in the axial direction if the winding body is constant or of different sizes, whereby this winding form is required for fast rewinding.

A combination of all the thread guide movements described above is not possible without a very complex mechanical conversion of the machine.

Task

The invention is based on the object of proposing a winding machine with a device in which the required thread guide movements and thus different windings in the structure can be produced in a simple manner without complicated conversion of the winding machine.

Advantages of the invention

The object is achieved according to the invention in that a plate with a stepper motor is advantageously mounted above the winding body, which, for example, activates a lifting arm via a toothed belt, which is attached to a lifting rail. The individual thread guides, which are individually, mechanically infinitely adjustable, are in turn attached to the lifting rail. The lifting rail can be easily mounted in self-lubricating plastic or between rollers.

In a preferred embodiment, the revolutions of the stepper motor and thus the movement of the lifting arm are advantageously initiated via a programmable controller.

drawing

The invention is explained with reference to the drawing, which shows a schematic view of an embodiment of a winding machine with a stepper motor drive of the thread guide.

Description of an embodiment

The winding machine according to the embodiment shown in the figure has a winding body 1, which carries a winding 2, for example made of threads 10 after winding has taken place. The threads 10 are guided from a supply winding 15 through a thread guide 3. A plate 4 with a stepper motor 5 is mounted above the winding body 1. The stepper motor 5 actuates a lifting arm 7, which is held on a lifting rail 8, via a toothed belt 6.

The individual thread guides 3 are attached to the lifting rail 8 and are individually, mechanically infinitely adjustable. The lifting rail 8 is mounted in self-lubricating plastic 9 or can also be mounted between rollers not shown here. The stroke of the thread guides 3 is indicated schematically with an arrow 11, whereby the arrows 12 represent a shortening of the stroke of the thread guide 3 per revolution of the winding body 1 and the arrows 13 indicate a constant stroke of the thread guide 3 during the winding process.

The stepper motor 5 and thus the movement of the lifting arm 7 can be controlled, for example, in the following way:

1. A movement of the lifting arm 7 and thus of the thread guide 3 linearly back and forth depending on the rotational speed of the winding body 1. This described movement of the thread guide 3 creates a rectangular winding structure (rectangular strand).

2. The turning times of the thread guide can be controlled depending on the speed of the winding body 1.

3. The stroke of the thread guide 3 can be specified in mm and thus the winding length can be adjusted.

4. The number of loops (revolutions of the winding body 1) can be specified.

5. A stroke reduction of the thread guide 3 per revolution of the winding body 1 can be specified. This described revolution of the thread guide 3 creates a trapezoidal winding structure on the winding body 1 (trapezoidal strand).

6. A displacement of the thread guide 3 in the axial direction of the winding body 1 can be specified per revolution of the winding body 1. This described movement of the thread guide 3 produces a trapezoidal strand, the cylindrical middle part of which is adjustable to be longer than the stroke of the thread guide 3 (Kötzer strand).

7. A changed stroke length of the thread guide (3) after a predeterminable number of revolutions of the winding body 1 and a predeterminable number of changed strokes and a return to the initial situation.
