Field of application of the invention

The invention relates to a Zentralbandwickler for winding electrical or optical lines with two or more bands of insulating material and / or metal foils.

Characteristic of the known state of the art

For winding electrical or optical lines with tape-shaped insulating material and / or metal foils exist a variety of technical solutions that can be distinguished by the arrangement of their tape rolls in the main groups Radialbandwickler Tangentialbandwickler and Zintralbandwickler. Their technologically specified boundary regions are essentially determined by the geometrically predetermined centrifugal force effect on the tape rolls. The lowest centrifugal force on the rolls of tape is recorded in Zentralbandwicklern, wherein at the same speed of the winding heads in this case the wires to be wrapped are least burdened in the banding process.

Central band winder solutions are known in which the lines to be wrapped can be wound with both a and a with several bands.

A disadvantage of the winding with only one band is the buckling of the continuous, to be banded lines under the tensile force of the band (see DE-OS 3042 531).

In DE-PS 2656643 a Zentralbandwickler is described in which a plurality of tapes were wound on a delivery reel, which in turn is received in the winding head. These bands are simultaneously pulled from different locations of the spool.

However, a major disadvantage of this solution is given by the mass accumulation at the common discharge point of the bands, which limits the technological application of such a Zentralbandwicklers strong.

In DE-WP 269900 a tape wrapper is described which overcomes the disadvantages of the above-mentioned. Winder types does not have. A considerable disadvantage of this invention, however, is the complicated storage of the winding head. Since the tape guide of the inlet-side tape roll must be carried out within the winding head bearing, only tape rolls with a small outer diameter can be used. Furthermore, the high peripheral speed of the winding head bearing limits the winding head speed.

Object of the invention

The aim of the invention is to develop a Zentralbandwickler for winding electrical or optical lines with two or more bands, which ensures a quality-friendly, gentle winding with a simple design.

Explanation of the essence of invention

The invention has for its object to develop a Zentralbandwickler for winding electrical or optical lines with two or more bands, which consists of a winding head, which in turn has a cantilevered rotor shaft on which two or more tape rolls are arranged one behind the other, wherein the Zentralbandwickler further technical means are assigned, which ensure low stress on the bands and electrical or optical conductors and a continuous winding and the bands largely of negative external influences, such as

Air turbulences, free.

According to the invention, this object is achieved in that on the rotor shaft, a magazine, which has separately stored and braked tape reels and a magazine with tape rolls overlapping, open in the withdrawal direction winding bell are arranged rotatable but detachable.

To Erf indungsumfang further includes that associated with the inner periphery of the winding bell each tape roll, uniformly distributed over the circumference tape guide elements in the form of a respective convex and cylindrical guide pulley and a respective deflecting pin, each convex Umlenkrolf 3 radially over the associated tape roll and paraxial to the rotor shaft, the associated deflecting pin perpendicular to the axis of rotation of the rotor shaft, but offset at the periphery of the winding bell to the convex guide roller and the associated cylindrical guide roller in the withdrawal direction in alignment with the deflecting pin and slidably, but perpendicular to the axis of the Umlenkstiftes, are arranged in the outlet side region of the winding bell. Furthermore, according to the invention, that the winding head is followed by a magazine recorder with tape storage and the Zentralbandwickler arranged according to need several winding heads, each with associated Magazinaufnehmer and tape storage in a row, may have

 The following describes the function of the invention:

The winding head of the central belt winder consists of a cantilevered rotor shaft, on which an openable in the withdrawal direction winding bell and a magazine are rotatably but detachably arranged. Furthermore, the magazine separated from each other and stored braked tape roles are assigned. These are covered by the winding bell and thus against harmful external influences, such. B. air turbulence, protected. The braking of the tape rolls can be done by controlled or unregulated Gleitreibungs- or rolling friction brakes or electric brakes. The bands are pulled off in alignment from their respective roll of tape and guided over the associated, a safe tape realizing convex deflection roller, which is arranged on the winding bell inside. There, the respective band is set around its center axis and guided over the associated deflection pin in the withdrawal direction of the conductor to be wound to the cylindrical guide roller. This cylindrical guide roller is to realize a variable adjustment of the overlap of the bands in the direction of the axis of rotation of the Rotorwe! '. designed to be movable.

Due to the uniform distribution of the tape guide elements over the inner circumference of the winding bell and thus the flow points of the bands, the Bandzugkräfte which act on the conductor to be wound compensate each other. For loading or setting the brake, the magazine is pulled by the shaft and pushed onto a magazine retainer with a roller storage device arranged downstream of the winding head: it is then fed with reserve tape rollers. The empty rolls of tape are slotted and can therefore be removed without problems from the overall system. In order to be able to realize a multi-layer winding, several winding heads are arranged one behind the other, each with associated magazine pickup and reel storage.

embodiment

The invention will be explained in more detail with reference to an embodiment. Show it:

Fig.3: winding head with magazine receiver and tape roll storage.

The winding head 1 of the central belt winder is gem. Fig. 1 from a cantilevered rotor shaft 2 and the fixedly connected with her winding bell 3. The entire winding head 1 is mounted in the rotor bearing 4. The drive of the winding head 1 via the drive element 5. With the rotor shaft 2, the magazine 6 rotatably but releasably connected, which get'ennt from each other and stored braked belt rollers 7 has. Magazine 6 and tape rolls 7 are covered by the winding bell 3. The conductor 8 to be wound is guided by a protective tube 9, which is supported in the rotor shaft 2. For better guidance of the line 8 is a guide nipple 10. The individual bands 11 are of their respective roll of tape? deducted in alignment and on an associated, a safe tape realizing convex deflection roller 12, which is arranged on the winding bells inside out. There, the respective band 11 is set around its central axis and guided via an associated deflection pin 13 in the drawing-off direction of the conductor 8 to be wound to form a cylindrical deflection roller 16.

Each convex deflection roller 12 is gem. 2, the associated deflection pin 13 perpendicular to the axis of rotation, but offset at the periphery of the winding bell 3 to the convex Uml6nkrolle 12 and the associated cylindrical guide roller 14 in the withdrawal direction in alignment with the guide pin 13 and slidably However, perpendicular to the axis of the deflecting pin 13 in the outlet side region of the winding bell 3, arranged. Furthermore, the individual tape guide elements of all associated tape rolls 7 are evenly distributed over the inner circumference of the winding bell 3. For loading or B.-amseneinstellung the magazine 6 is pulled by the rotor shaft 2 and gem. Fig. 3 is placed on a winding head 1 downstream magazine receptacle 15 with tape storage 16, then optionally with

Reserve tape rolls 17 to be fed. In order to be able to realize a mohrlagige winding, several, not shown winding heads 1, each with associated Magazinaufnehmer 16 and Bandroleverpeicher 1 β are arranged one behind the other. Instead of the tape roll 16 can also Bespulvorrichtungen be included in the facilities. The advantage of the invention is the reduction of negative effects, e.g. Luftverwirbelung, on the bands 11 by the arrangement of the tape rolls 7 covering the winding bell. 3
