Definitions
- Heating device for a moving material web in particular preheaters for a corrugated cardboard system
- the invention relates to a heating device for a moving material web, in particular a preheater for a corrugated cardboard system with the features of
- Such a heating device is known for example from DE 23 02 449 C3.
- This device consists of a heating roller, which is preferably heated by steam as the heating medium.
- the material web is heated in that the heating roller is wrapped around the material web with a predetermined wrap angle.
- two guide rollers are provided in the known device, which can be pivoted about the outer circumference of the heating roller.
- the guide rollers have a fixed relative position to one another and are arranged for this purpose on two rigidly connected arms. The arms can be pivoted together about the axis of the heating roller by means of a suitable drive.
- the two guide rollers are out of engagement with the material web.
- the material web which is fed via a rigid guide roller on the inlet side, runs with a certain remaining wrap angle around the heating roller to form a rigid guide roller on the outlet side.
- the two pivotable guide rollers can be pivoted from this position in the circumferential direction until the front deflection roller comes into engagement with the material web. Will the two guides pivoted further, the wrap angle increases accordingly. In order to avoid grinding of the web strand between the rigid feed-side guide roller and the roller defining the wrap angle, this web strand with the second pivotable guide roller is exceeded when a certain pivot angle is exceeded (calculated from the position with a minimal
- a maximum wrap angle is made possible with this known heating device. Furthermore, in the position with the minimum wrap angle (residual wrap angle), this embodiment ensures extremely simple feeding of the material web to be heated. Because this only has to be passed between the peripheral surface of the heating roller and the two pivotable guide rollers.
- a disadvantage of this heating device is that a certain remaining wrap angle remains and, consequently, a certain minimum thermal energy is inevitably supplied to the material web.
- a device for preparing tape-like material to be glued, such as corrugated cardboard is also known, in which the material web is also guided around a pivotable guide roller.
- a further guide roller engages with this known device, which in this position completely lifts the material web from the peripheral surface of the heating roller.
- the material web runs in an S-shape between the two guide rollers.
- the in the position with zero Wrap angle lifting the material web guide roll is in turn rigidly connected to the guide roll defining the wrap angle.
- Both guide rollers can be pivoted about the axis of the heating roller by means of a pivotable arm. In this known device, the energy supply to the material web can thus be completely switched off in the position with zero wrap angle.
- a disadvantage of this known device is that only a relatively small maximum wrap angle can be achieved.
- an increase in the heated length can only be achieved by an increase in the heating roller diameter. This entails considerable costs.
- the object of the invention is to provide a heating device for a moving material web, in particular one
- a third guide which, of course, can in turn be designed as a guide roller in a heating device according to DE 23 02 449 C3, gives both the advantage of a maximum achievable wrap angle (and thus a maximum heatable length of the material web) and on the other hand varying the wrap angle or the heatable length to zero.
- all the guides are connected to a support part which can be pivoted about the axis of the heating roller. All guides can have the same distance from the circumference of the heating roller.
- the third, lifting the material web in the position with zero wrap angle guide is arranged in the preferred embodiment of the invention, seen in the circumferential direction of the heating roller, at a minimum permissible distance from the first guide.
- This has the advantage of a maximum wrap angle, since the three jointly pivotable guides can be pivoted by the maximum possible angle before the third guide comes into contact with the incoming or outgoing run of the material web.
- the third guide in the radial direction (based on the heating roller) must be arranged so that in the position with zero
- the material web is fed via a rigid inlet-side guide and a rigid outlet-side
- the inlet-side and outlet-side guide lying essentially on a straight line with the axis of the heating roller. This gives the advantage of a maximum possible wrap angle. This is approximately 270 to 280 °.
- the third guide with respect to the heating roller, can be offset radially outward with respect to the first guide.
- the first and third leadership are in the position of the nominal wrap angle (zero wrap angle) wrapped in an S-shape by the material web.
- the third guide is arranged within the central angle defined by the axes of the first and second guide and the axis of the heating roller, the guides can be pivoted until the first guide does not come into contact with the run side or run side Material web device. This results in a maximum wrap angle.
- the first and third guides are wrapped extremely S-shaped in the position of the zero wrap angle. This in turn would make it difficult to thread the material web, for example after tearing.
- the third guide can be moved from the normal working position into a position, seen in the circumferential direction of the heating roller, before the first guide into an inviting position. This can preferably be done by pivoting the third guide about the axis of the first guide.
- the third guide can preferably be designed to be lockable in the threading position and / or the working position.
- Figure 1 shows a first embodiment of the heating device according to the invention with three guide rollers in the position of the zero wrap angle.
- Fig. 2 shows the embodiment in Fig. 1 in the position with the maximum wrap angle and
- Fig. 3 shows a further embodiment of a heating device according to the invention, which ensures the maximum possible wrap angle.
- Fig. 1 shows a schematic side view of a first embodiment of a heating device according to the invention.
- the heating device 1 comprises a heating roller 3, which is mounted in a machine frame 5 which is only shown schematically and is rotatably driven.
- the heating roller 3 can be heated by means of superheated steam, for example.
- the heating device 1 further comprises three guides 7, 9, 11, which can preferably be designed as guide rollers.
- a material web to be heated is fed to the heating device 1 via a stationary inlet-side guide 15 and discharged via a likewise stationary outlet-side guide 17.
- the stationary guides 15, 17 can either be integrated in the heating device 1 or can be a component of upstream or downstream machines or system parts.
- the material web 13 to be heated is first fed to the guide roller 9 and runs from there to the stationary outlet-side guide roller 17 without touching the heating roller 3.
- the guide rollers 7, 9, 11 are preferably rotatably held on a part 19 pivotable about the axis A.
- corresponding pivotable parts 19 can also be provided on both sides of the heating roller 3, which pivotally support the guide rollers 7, 9, 11 on both sides.
- the pivotable side parts 19 can then by a suitable drive around the
- Axis A of the heating roller 3 can be pivoted.
- FIG. 2 shows the maximum wrap angle ⁇ max in the embodiment according to FIG. 1. In this position of the guide rollers 7, 9, 11, the guide roller 9 just does not touch the run side run of the material web. Another one
- this strand 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 there 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 the material web already wrapped around the heating roller.
- Guide rollers 7, 9, 11 both a zero wrap angle (Fig. 1) and a large maximum wrap angle ⁇ max can be achieved.
- FIG. 3 essentially corresponds to the embodiment according to FIGS. 1 and 2.
- the further embodiment of the invention shown in FIG. 3 essentially corresponds to the embodiment according to FIGS. 1 and 2.
- Guide roller 9 is arranged so that in the normal working position, with respect to the heating roller 3, it is essentially radially outward of the guide roller 7 that defines the wrap angle.
- the guide roller 9 can of course be designed to be lockable in the threading position or in the normal working position.
- This embodiment shown in FIG. 3 has the advantage that the guide roller 7, which defines the wrap angle, can be pivoted practically up to the run-side run of the material web 13. In contrast to the embodiment according to FIGS. 1 and 2, the maximum achievable
- the guide roller 11 In this position of the maximum possible wrap angle shown in solid line in FIG. 3, the guide roller 11 must of course still ensure that the run-side strand of the material web 13 does not come into contact with the peripheral surface of the heating roller 3 or the material web wrapped around it.
- the position of the guide roller 11 can be freely selected within wide limits.
