Definitions
- the invention relates to a heating device for a corrugated cardboard system with the features the preamble of claim 1.
- Heating devices for a corrugated cardboard plant are known. These so-called heating sections have several heating plates arranged in the running direction of the corrugated cardboard web, which are mostly heated by superheated steam. These heating plates form with their top a flat, smooth heating surface.
- the corrugated cardboard web runs continuously over this heating surface Speed. It is powered by a continuous belt and pressure devices in the form of mechanical pressure rollers or pneumatic pressure hoods pressed against the heating surface.
- the pressing device and / or the temperature of the Heating surface depends on factors such as Running speed of the corrugated cardboard web, Humidity values and the like, controllable. It can be in the corrugated board plant or be provided separately from these train parts.
- the disadvantage is that the temperature of the Heating plates cannot be changed quickly.
- JP-A-3-118146 describes a method for producing a Non-slip corrugated sheet in which a cover sheet with a non-slip Surface is glued with a one-sided corrugated sheet.
- a device is provided for pressing the two webs to be glued from a device arranged below the sheets to be glued a metallic endless belt, which is guided around two pulleys, and one device with several, arranged above the sheets to be glued used the necessary pressure generating roles.
- the metallic endless belt is heated. The heating is carried out indirectly by heating one of the two deflection rollers.
- the invention lies Task to create a heating device for a corrugated cardboard system in which even in the event of rapid or sudden changes in the process parameters or parameters the incoming corrugated cardboard web, in particular its moisture, as constant as possible Quality of the outgoing corrugated cardboard web is guaranteed.
- the heating device has a heated metal strip running at the speed of the corrugated cardboard and arranged below the corrugated cardboard strip largely prevents friction between the strip and the corrugated cardboard strip. The necessary output for the corrugated cardboard web is reduced.
- the heated metal strip has a low mass, the temperature of which can be changed quickly. A faster adaptation to the conditions and conditions of the corrugated cardboard web, such as, for example, the moisture, speed or the like, is thus possible.
- the heated metal strip is preferably a steel strip. This is particularly low-wear and can withstand the corresponding tensile and stretching forces.
- the temperature of the metal strip can be controlled or regulated so that the outgoing web can be kept largely constant with respect to its temperature or humidity, even if change the relevant parameters of the incoming web relatively quickly.
- the metal strip is vapor-permeable.
- the Metal tape can be designed as a perforated tape, webbing or the like. That is the corrugated cardboard web covering metal tape this way allows the moisture from the corrugated cardboard web or the glue application can escape to the outside.
- the metal strip can be made in different ways are heated, e.g. by steam, hot gas, hot liquid, an infrared source, an induction source or a high frequency source.
- the heating source can also be a pressing device form the metal strip on the corrugated cardboard web.
- two heatable metal strips are used which act on the top and bottom of the corrugated cardboard web. This has the advantage that no sliding friction occurs between the corrugated cardboard web and the heating devices, and curvature of the web is largely avoided by uneven heating of the top and bottom web. Furthermore, the static friction between the belts and the web enables the belts to function simultaneously as a means of transport. Further refinements of the invention result from the subclaims.
- the heating device 1 has a stand 2, which is lying one behind the other arranged heating plates 3 can wear.
- the top of the heating plates 3 form one flat, smooth heating surface 4.
- the heating plates 3 can be divided transversely to the running direction of the corrugated cardboard web 5.
- the heating plates 3 can be replaced by any heating means, e.g. Steam, gas, electrical heating means or the like heated become.
- the temperature of the heating surface can be predetermined Temperature value can be set.
- the temperature value can be in the longitudinal or transverse direction of the running direction of the corrugated cardboard web 5 can be specified. It is also possible to get these temperature values depending on the speed of movement of the To control corrugated cardboard 5.
- the control of the heating plate temperature can also be via sensor, depending on the humidity the corrugated cardboard web 5 or the amount of glue applied to the Corrugated cardboard 5 take place, possibly in the form of a closed Control loop.
- the moving over the heating surface 4 and adjacent to this Corrugated cardboard web 5 runs at the inlet end 6 of the heating surface to and at the outlet end 7 out. It moves in the specified Arrow direction I.
- the metal strip 10 is preferably a steel strip. This can can also be provided with holes 30, as can be seen in FIG. 2. Moisture vapor can escape from the corrugated cardboard web via these holes 30 5 pull off through the metal strip 10. The moisture vapor stems from the corrugated cardboard web 5 itself or from the applied glue.
- the metal strip 10 can also, as can be seen from FIG. 3, from Woven fibers 31, which run in the longitudinal direction and are mutually wounded. It arises between the Fibers of metal, preferably steel, penetration gusset for the moisture vapor.
- the metal strip 10 is preferably at the speed of movement the corrugated cardboard web 5 driven. hereby there is no friction between band 10 and the corrugated cardboard web 5.
- the belt 10 can simultaneously act as a conveyor belt or at least support the conveying of the corrugated cardboard web 5.
- the heating device can also be designed such that the Metal strip 10 acts on the underside of the corrugated cardboard web 5. This has the advantage that one Do not tear the web 5 over the metal plates 3 grinds as soon as the pressure medium is released.
- heating plates 3 could be of conventional design also by other heating plates and by other known electrical ones Induction plates or the like can be replaced.
- pressing devices 17 are located above the lower strand 16 of the endless belt 10 one or more pressing devices 17, the lower Run of the endless belt 10 against the top of the corrugated cardboard web Press 5.
- These pressing devices 17 can be mechanical Type, e.g. as is known, by lifting and lowering pressure rollers or be formed pneumatically by pressure hoods. The pressing devices 17 determine the transferred thermal energy on the corrugated cardboard web 5.
- the pressing devices 17 can also be formed by housings be heated by superheated steam or hot gas.
- Heating sources e.g. Infrared sources, induction sources or to provide high frequency sources for the metal strip 10.
- Such heat sources can be used on any Be provided for the metal strip, in particular also the strand that does not act on the corrugated cardboard web 5.
- the incoming one-sided corrugated cardboard 20 and / or cover sheet 21 and / or the outgoing corrugated cardboard web 22 are sensors 23, 24 or 25 assigned.
- the pressing devices 17 Via a control device, not shown can the pressing devices 17 depending on the temperature or humidity values measured by the sensors can be controlled with regard to the contact pressure. If the measured values exceed a predetermined value, the pressure values of the pressure devices 17 are reduced and vice versa.
- the temperature or humidity of the tapering tracks are influenced by a known Preheater with heating drum is used, its temperature or the wrap angle is controlled.
- a vacuum source As such known to be attached.
- Fig. 4 shows a second embodiment of the invention Heater, in the above and below the one to be heated Corrugated cardboard 5 metal strips 10 are provided. hereby there is the advantage that between the heat to be supplied Areas, i.e. the outer surfaces of the heated metal strips 5, and the corrugated cardboard web to be heated none at all Friction is generated. This will shift the individual Sheets of corrugated cardboard avoided during the drying process. This in turn produces distortion-free corrugated cardboard, the stacked to save space and easily processed can be.
- the two circumferential metal strips 10 and those interacting therewith Components are basically the same, like the metal strip of the embodiment according to FIG. 1 can be referred to the above statements.
- the dreams of the metal strips adjacent to the corrugated cardboard web 5 10 are each in the direction of the corrugated cardboard Pressure chambers 30 acted upon, the medium of the pressure chambers, preferably steam or hot gas, at the same time that for heating the web 5 required amount of heat and the pressure supplies the metal strips 10 to the web 5.
