Definitions
- the invention relates to a winding tube for winding tapes, foils, sheets or the like, which consists of a helically wound metal strip, the adjacent strip winding of which at least partially overlap, the metal strip having a corrugated or ribbed profile in cross section.
- the invention also relates to a method for producing a winding tube.
- winding cores or winding cores made of cardboard, plastic or metal, in particular aluminum are known.
- the cardboard cores which are used particularly frequently and which can usually only be used once, but can also be used several times, are relatively heavy and cause problems in disposal. Since these sleeves, like the sleeves made of plastic and metal, must have a high wall strength and bending strength under radial loading, they usually consist of many layers of transversely and / or overlapping wound and glued together Kraft paper webs.
- An improved winding tube is known from EP 0 729 911 AI. It consists of a metallic corrugated tube, which is formed from a helically wound, longitudinally corrugated or longitudinally ribbed band, with adjacent band windings overlapping at least at their edges, preferably at least by half their bandwidth, so that an at least two-layer sleeve wall is formed.
- the known winding tube preferably has a smooth, uninterrupted outer wall surface, which arises from the fact that the shafts or ribs have a rectangular or trapezoidal cross section, so that the shaft or rib heads abut one another on the outer and inner walls of the sleeve. Then the outer and the inner shaft heads of the sleeve are wider than the gaps between these shaft heads, which are referred to in the said patent as "shaft feet".
- a tube is first produced by helically winding a longitudinally corrugated or longitudinally corrugated metal band with band windings overlapping at its edges.
- the shaft heads are then flattened by exerting a radial pressure on the tube and at the same time widened.
- the tube can be compressed in the axial direction in such a way that the gaps between the heads are further reduced or closed.
- both the shaft heads on the outer tube wall and the shaft heads on the inner tube wall collide, which gives the resulting winding tube a special stiffness. Winding cores are then cut to the desired length from the resulting tube.
- the gaps between adjacent shaft heads cannot be completely closed simply by flattening the shaft heads. There is therefore no smooth outer tube wall, but gaps remain between the adjacent shaft heads, which damage the material to be wound or at least make the winding process more difficult. Compression of the winding tube in the axial direction is therefore inevitable.
- the known winding tube has a comparatively high weight in relation to the crest compressive strength, i.e. for the radial deformability of the winding tube. For the two reasons mentioned, the manufacture of the winding tube is therefore disproportionately complex.
- the invention is therefore based on the object of providing a winding tube, the manufacture of which is less complex than that of the known winding tube and which nevertheless has a smooth outer wall and high strength, and a method for producing such a winding tube.
- the winding tube according to the invention has a smooth outer wall and that at the same time the material of the longitudinally corrugated or longitudinally corrugated metal strip can be used efficiently, so that there is an improved relationship between the weight and the crest compressive strength of the winding tube.
- the pre-profiled metal strip is designed so asymmetrically that the outer shaft heads on the later tube outer side are wider than the inner shaft heads on the later tube inner side, because the gaps between the outer shaft heads are already compared with the initial profile the outer shaft heads themselves are relatively small and can be easily closed by pressing the outer shaft heads flat.
- more material is available for the profile webs, i.e. for the area between the outer and inner shaft heads, which benefits the radial deformation resistance and the section modulus of the overall profile.
- adjacent shafts / ribs of the profile of the winding tube abut each other or almost in sections of their outer head regions located on the outer wall of the core, and the inner head regions of the adjacent shafts / ribs located on the inner wall of the core are completely spaced apart.
- the shaft heads located on the outer wall of the sleeve touch each other and are nevertheless designed to be round, it is preferred that the shaft heads are designed flat.
- the outer wall of the resulting winding tube then not only has no gaps between the individual outer shaft heads, but moreover corresponds in longitudinal section to an essentially straight line.
- the winding tube according to the invention thus developed is particularly well suited for winding flat strip material, e.g. of aluminum webs, which would deform in the case of a less smooth outer sleeve wall during winding, so that at least the innermost layers of the wound material would not be usable without restrictions.
- a smooth outer wall of the winding tube is obtained, for example, by designing the outer shaft heads to have a trapezoidal cross section.
- the inner shaft heads on the inner wall of the sleeve can be round, in particular they can retain the shape that was given them when the metal strip was profiled.
- the metal strip can advantageously be wound in such a way that the strip windings overlap by at least half of their strip width.
- the resulting tube wall then consists of at least two tape layers, which further improves the strength of the winding tube.
- a cover layer made of a film can be glued, sealed or otherwise attached to the tube outer wall.
- a flat metal strip is first formed into a longitudinally corrugated or longitudinally ribbed pre-profile strip, the wave or rib flanks of which form a flank angle ⁇ with a perpendicular on the plane of the metal strip.
- the longitudinally corrugated or longitudinally ribbed strip is then wound in a helical manner in such a way that adjacent strip windings overlap at least partially, so that a tube is formed.
- the metal strip has a corrugated or ribbed profile in cross section, the outer shaft heads of which after winding on the outer wall of the sleeve are wider than those of the inner shaft heads after winding on the inner wall of the sleeve.
- the outer heads of the shafts or ribs located on the outside of the tube are then flattened and widened by exerting a radial pressure on the tube.
- the resulting tube is then cut into winding sleeves of the desired length.
- the method according to the invention offers the advantage that a very rigid and resistant winding tube can be produced at a low overall weight with little effort. Since the initial profile is already so asymmetrical that the outer wave heads on the later pipe outer wall are wider than the inner wave heads on the future raw inner wall, the gaps between the outer wave heads of the initial profile are already relatively small in relation to these outer wave heads. To close these gaps, the outer shaft heads need only be flattened to a small extent or wide. The time-consuming subsequent upsetting required in the known manufacturing process is eliminated.
- the profile is designed so that relatively little material can be used for the inner shaft heads, so that all the more material for the webs between the outer and is available to the inner wave heads. The more material used for these webs, the higher the radial deformation resistance of the winding tube.
- the inner shaft or rib heads located on the inside of the tube remain completely spaced apart from one another.
- the flank angle ⁇ of the pre-profile strip is preferably approximately 5 °, so that the pre-profile strip can be easily wound into a tube.
- the pre-profile strip initially has a flank angle ⁇ which is between 15 ° and 25 °. Then the pre-profile strip can be stacked, which means that when winding several strip windings on top of each other, the flanks of the underside of the strip lie evenly on the flanks of the top of the strip.
- the profile is not twisted, driven apart or otherwise deformed.
- the preliminary profile can therefore be wound onto a primary material spool, the diameter of which increases only comparatively slowly when the specially designed preliminary profile is wound up.
- the profiled strip can be guided onto the raw material roll by a profile roller which is straight or curved in the radial direction in the region of the run-up point of the profiled strip. This ensures that the strip layer edges are placed exactly on top of each other and the profile strip is wound straight.
- the flank angle ⁇ of about 5 ° is expedient, as described above.
- the pre-profile strip with the flatter flank angle ⁇ is therefore further deformed, possibly rolling off from the pre-material spool just described, until the flank angle ⁇ of about 5 ° is reached.
- the pre-profile strip can be manufactured at a first manufacturing facility, wound up to a primary material spool, transported to a second manufacturing facility and further processed there to the winding tube according to the invention. The latter preferably occurs where the winding cores are later also required for winding tapes, foils, etc. Then there is no need to transport empty winding tubes that require a lot of storage space.
- the distances between the shafts or ribs of the metal strip are reduced even further before or during the subsequent winding process.
- the shafts are pushed together, which is preferably done by means of guide rollers used in the winding process. This makes it easier for the outer shaft heads to be compressed, since the shaft heads no longer need to be compressed as much with small distances between the shaft heads. A comparatively small compression is sufficient to close the gaps between the shaft heads.
- FIG. 1 shows a cross section through a pre-profile strip that can be used to produce a winding tube according to the invention after a first deformation step of the method according to the invention
- FIG. 2 shows a cross section through a profile strip that can be used to produce a winding tube according to the invention after a further shaping step
- Fig. 3 shows a cross section through two interlocking
- Fig. 4 shows a cross section through two interlocking
- FIG. 5 shows a longitudinal section through a wall of a winding tube according to the invention
- FIG. 6 shows a profiling device that can be used in the method according to the invention
- 7 shows a winding device that can be used in the method according to the invention
- FIG. 7a is an enlarged view of the left part of FIG. 7,
- FIG. 8 shows a guide roller which can be used in the method according to the invention.
- Fig. 1 shows a metal strip, preferably an aluminum strip, which has been formed into a longitudinally corrugated pre-profile strip.
- outer shaft heads 1 of the profile are wider than the inner shaft heads 2 of the profile.
- the outer shaft heads 1 will later be arranged on the outer wall of the winding tube being formed, the inner shaft heads 2 on the inner wall.
- a wave flank forms a flank angle a with a perpendicular on the band plane, which lies between 15 ° and 25 °.
- the profile belt shown in Fig. 1 is stackable or rollable, so it can be temporarily stored or transported in this form.
- the device shown in FIG. 6 can be used, for example, to profile this aluminum strip.
- the metal strip runs from a first spool 3, is greased in a device 4, profiled by first profiling rollers 5 and rolled up onto a primary material roller 6.
- the profiled strip is guided onto the raw material roll 6 by a profile roller 13, which is straight or curved in the radial direction, in the region of the run-up point of the profiled strip. This ensures that the strip layer edges are placed exactly on top of each other and the profile strip is wound straight.
- flank angle has decreased to an angle ⁇ and is now approximately 5 °.
- the material is therefore no longer stackable as well as the pre-profile strip, but the steeper flank angle is favorable in order to achieve a smooth surface of the winding tube in the subsequent winding process.
- the pre-profile strip runs from the pre-material roll 6 and is formed by second profiling rolls 7 in order to form the flank angle ⁇ .
- 3 and 4 show the metal strip during the winding process. 3 that two layers of the metal strip interlock.
- the metal strip still has the profile shown in FIG. 2.
- the waves of the profile are pushed further together, so that the profile shown in FIG. 4 is created.
- This process step also serves to subsequent winding process to achieve a smooth surface of the outer wall of the winding tube with little effort.
- Fig. 5 shows the final profile of a winding tube according to the invention as a longitudinal section through a wall of such a tube.
- the wide outer shaft heads 1 of the profile have been flattened, so that there is a smooth, uninterrupted outer wall of the winding tube. Due to the previous process steps, i.e. due to the steep flank angle ß and the pushing together of the shafts, only a comparatively small radial force was necessary to flatten the outer shaft heads.
- the comparatively small inner shaft heads 2 have not been deformed any further.
- a high bending stiffness of the winding tube nevertheless results due to the uninterrupted outer wall and the fact that a relatively large amount of material has been used for the profile webs 12 between the outer and inner shaft heads 1 and 2.
- a winding device is used to wind the tape into the winding tube according to the invention.
- the winding sleeves made of profiled tape can be produced with two different winding devices, the first of which is shown in the left part of FIG. 7 and consists of a winding mandrel 8 and profiled guide rollers 9.
- 7a is an enlarged view of this winding device with winding mandrel.
- the web strip is bent around the winding mandrel 8.
- six guide rollers 9 are provided for this purpose, but depending on the tube diameter, more or fewer guide rollers 9 can also be present.
- a three-roll bending apparatus 10 gives the strip strip the desired curvature.
- the guide rollers 9 also cause the strip to run helically.
- a counter roller 14 is arranged here since there is no winding mandrel.
- the guide rollers 9 are each profiled so that their webs fill the gaps between two shaft heads. Each guide roller 9 engages over several band windings in the profile of the tubes. In order to reduce the shaft spacing of the profile during the process, the guide rollers 9 can also be divided into sections that cover the belt pitches.
- FIG. 8 shows a guide roller 9 which is divided into four sections A to D, the distances between webs 15 of the guide roller 9 decreasing from section to section.
- section A the profiled band is passed around the mandrel without reducing the spacing between the shafts.
- sections B and C the distances between the shafts from guide roller 9 to guide roller 9 are reduced.
- the outer shaft heads are then flattened in one step or in several steps, for example by means of section D of some guide rollers 9.
- FIG. 9 shows a profiling and winding device according to the prior art.
- a metal strip 3 is greased in a device 4, then pre-profiled with first profiling rollers 5, further formed with second profiling rollers 7 and finally wound up in a winding device 8, 9.
- the device used is comparatively large and the entire manufacturing process has to be carried out in a single process.
- the method according to the invention allows the production process to be divided and thus the size of the devices used to be reduced.
