Definitions

  • the invention relates to a heating device for a moving material web, in particular a preheater for a corrugated board system with the features of Preamble of claim 1.
  • Such a heating device is known for example from DE 23 02 449 C3.
  • This device consists of a heating roller, preferably by Steam can be heated as a heating medium.
  • the material web is heated in that the heating roller from the material web with a predetermined Wrap angle is wrapped.
  • two guide rollers are in the known device provided which is pivotable about the outer circumference of the heating roller are.
  • the guide rollers have a fixed relative position to each other and are arranged on two rigidly connected arms. The poor are together by means of a suitable drive around the axis of the heating roller swiveling.
  • the two pivotable guide rollers can be circumferentially from this position be pivoted until the front deflection roller in the swivel direction comes into engagement with the material web. Will the two guides pivoted further, the wrap angle increases accordingly.
  • this track strand with the second swivel guide roller from crossing a certain swivel angle (calculated from the position with minimal Wrap angle) held at a sufficient distance from the heating roller.
  • this known heating device a maximum wrap angle enables. Furthermore, this embodiment ensures in position with the minimum wrap angle (remaining wrap angle) extremely easy feeding of the material web to be heated. Because this must only between the peripheral surface of the heating roller and the two pivotable Guide rollers are passed through.
  • a disadvantage of this heating device is that a certain residual wrap angle remains and consequently the material web is unavoidable a certain minimum thermal energy is supplied.
  • DE-OS 15 11 061 also describes a device for preparation of tape-like material to be glued, such as corrugated cardboard, known in the the material web is also guided around a pivotable guide roller.
  • a pivotable guide roller In the position in which a single guide roller is used minimal wrap angle would arise in this known device another guide role, which in this position is the material web completely stands out from the peripheral surface of the heating roller. In this position with a zero wrap angle, the material web runs in an S-shape between the two leadership roles. The one in the zero wrap angle position the material web lifting leading role is again rigidly connected to the guide roller defining the wrap angle.
  • Both guide rollers are pivotable about the axis the heating roller can be swiveled. In this known device can thus Position with zero wrap angle the energy supply to the material web be completely switched off.
  • the invention is based on the object a heating device for a moving material web, in particular one To create a preheater for a corrugated cardboard system with as little as possible Effort a maximum heated length of the material web is achievable and where at the same time the heated length can be easily varied to zero can be.
  • all of the guides are connected to a support part pivotable about the axis of the heating roller. All guides can be the same distance from the circumference of the heating roller exhibit.
  • the third, lifting the material web in the position with zero wrap angle Leadership is in the preferred embodiment of the invention, in Seen circumferential direction of the heating roller, at a minimum allowable distance arranged by the first guide.
  • the third guide must refer to the radial direction ( on the heating roller) so that it is in the position with zero wrap angle actually a lifting of the material web on the peripheral surface the heating roller takes place.
  • the material web fed via a rigid inlet-side guide and a rigid outlet-side Leadership removed, with the inlet and outlet side leadership with the Axis of the heating roller lie essentially on a straight line. This gives the advantage of a maximum possible wrap angle. This is approx. 270 to 280 °.
  • the third guide can be based on the heating roller, opposite the first guide in the radial direction to the outside be offset.
  • the first and third guides are in the position of the minimum Wrap angle (zero wrap angle) S-shaped from the Material web wrapped around.
  • the third guide within the through the Define axes of the first and second guide and the axis of the heating roller Arranged center point the guides can be pivoted so far until the first guide is not in contact with the inlet side or run side run of the material web. This results in a maximum Wrap angle.
  • the first and third guides wrapped extremely S-shaped. This would again threading the material web, for example after tearing, difficult.
  • the third guide can leave the normal working position in a position, seen in the circumferential direction of the heating roller, in front of the first guide can be converted into a threading position. This can preferably by pivoting the third guide around the axis of the first guide respectively.
  • the third guide can preferably be in the threading position and / or the working position can be designed to be lockable.
  • Fig. 1 shows a schematic side view of a first embodiment a heating device according to the invention.
  • the heating device 1 comprises one Heating roller 3, which is shown in a machine frame 5 shown only schematically is stored and rotatably driven.
  • the heating roller 3 can for example by means of Superheated steam can be heated.
  • the heating device 1 further comprises three guides 7, 9, 11, which are preferably can be designed as guide rollers.
  • the heating device 1 becomes a material web to be heated via a stationary one inlet-side guide 15 and supplied via an also stationary outlet-side Leadership 17 removed.
  • the stationary guides 15, 17 can either in the heating device 1 may be integrated or a component upstream or downstream Be machines or system parts.
  • the guide rollers 7, 9, 11 are on a pivotable about the axis A.
  • Part 19 preferably held rotatably.
  • corresponding pivotable parts 19 are provided be, which support the guide rollers 7, 9, 11 rotatably on both sides.
  • the pivotable Side parts 19 can then by a suitable drive to the Axis A of the heating roller 3 can be pivoted.
  • FIG. 1 A further intermediate position of the guide rollers 7, 9, 11 is shown in dashed lines. This position corresponds approximately to a pivoting the guides 7, 9, 11 by a pivoting angle of 180 °. In this position the web of material 13 is initially from the inlet-side stationary guide 15 fed to the guide roller 7, wraps around it and then runs to the peripheral surface the heating roller 3. This is wrapped with a wrap angle of approx. Wrapped 180 ° before the material web 13 over the outlet-side stationary Guide roller 17 is removed.
  • FIG. 2 shows the maximum wrap angle ⁇ max in the embodiment according to FIG. 1.
  • the guide roller 9 just does not touch the run side run of the material web.
  • a further pivoting of the guide rollers would in principle be possible, but would lead to the run-side run of the material web 19 being deflected due to the contact with the guide roll 9 in a direction in which this run would be lifted further and further from the peripheral surface of the heating roller 3.
  • the overall wrap angle that can be achieved would remain constant at most.
  • the guide roller 7, which defines the wrap angle is wrapped around as well as in the intermediate position shown in broken lines in FIG. 1.
  • the material web 13 runs from the stationary inlet-side guide 15 first to the guide roller 11 and only from this to the guide roller 7.
  • the guide roller 11 prevents the feed-side strand of the material web 13 from touching or grinding with the heating roller or material web already wrapped around the heating roller.
  • FIG. 3 corresponds to Essentially the embodiment according to FIGS. 1 and 2.
  • Guide roller 9 arranged so that it is in the normal working position on the heating roller 3, opposite the one defining the wrap angle Guide roller 7 is offset substantially radially outwards.
  • the guide roller 9 in the threading position or in the normal working position be designed lockable.
  • This embodiment shown in Fig. 3 has the advantage that the guide roller 7, which defines the wrap angle, practically up to the outlet side Run of the material web 13 can be pivoted. Different to in the embodiment according to FIGS. 1 and 2, the maximum achievable Wrap angle is not limited by the guide roller 9.
  • the wrap angle must always be the guide roller 11 still ensure that the run side run of the material web 13 if possible not in contact with the peripheral surface of the heating roller 3 or the looped around it Material web arrives.
  • the position of the guide roller 11 can do this can be freely chosen within wide limits.
