The material web comprises as a material paper and / or plastic and / or plastic film and / or heat-insulating material, wherein materials with metal / metallic / and / or heat-conducting components are excluded. Furthermore, in the context of the invention can be used with phenolic resin embossed paper, including HPL films (HPL = High Pressure Laminate) or CPL films (CPL = Continuous Pressure Laminate) and from the field of plastic Bakelite.

The method is practiced using one or more moving forming means with which or which the web is brought into positive engagement.

Furthermore, the invention relates in particular to the execution of said method suitable arrangements for reshaping the profile shape of a material web in a regular wave-like and / or periodic profile. For the material web, a conveying or transporting device is provided, which comprises one or more, moving or movable forming means, with which or which the material web is in positive engagement or can be set.

To the state of the art

In the DE 195 45 038 A1 the production of honeycomb panels will be described. A material web is folded transversely to the web direction, and the folded web glued offset on top and bottom. The folded section is folded with the glue lines and pressed. Thereafter, upper and lower edges of the material web are ground in the pressed state. Finally, the web is stretched uniformly and the stretched web in the desired Cut lengths. As the web is stretched, the honeycomb patterns defined by the bondlines are created. However, care is not taken for the precise adherence to a specific honeycomb profile shape.

For producing corrugated or ribbed heat exchanger fins it is known ( US 5,758,535 ) to pass unrolled metal tracks between toothed pairs of rollers and thereby impress a corrugated profile to form the cooling fins. At the beginning of the processing line, a mechanical tension is generated in the metal track by means of a pneumatic cylinder, which is monitored in the context of a control loop with strain gauges and readjusted by appropriate control of the pneumatic cylinder. In a subsequent processing step, the corrugated profile is compressed firmly. The corrugated profile forming the ribs is automatically monitored in the compressed state for its average height, which is readjusted if necessary. However, measures to maintain an exact shape of the embossed wave or rib profile are not recognizable.

Also in connection with the production of corrugated or ribbed cooling fins from metal sheets for heat exchangers, a method for controlling the respective length of finned and separated cooling fin parts is known (US Pat. US 5,207,083 ). A metal sheet is passed through a pair of forming rollers and thereby provided with a corrugated profile. The forming roll pair is driven by a main drive which is controlled by a main controller. In the further manufacturing process, the corrugated metal sheet is compressed and then stretched by means of pullout rollers back to a specific material density. For this purpose, the extraction rollers are driven by a servo drive via a coupling with the main control synchronously in phase with the forming rollers. To operate a length control loop, the respective length of the cut-off cooling plate parts is detected as an actual value. Deviating from a set point, the speed of the servo drive for the pullout rollers is changed for a fixed period of time, resulting in a phase shift of the servo drive and the pullout rollers relative to the main drive and forming rolls. This results in a change in the length and the rib pitch for the next, to be separated cooling fin part. The control or regulation for the servo drive The extraction rollers include a PI control algorithm to influence the length and rib pitch of the separated cooling fin parts in the aforementioned manner. However, by measuring the total length of a separated cooling fin part as an actual value and coupling it into the control loop, deviations from compliance with the specific profile shape or shape are not detected. Certain inaccuracies in the shape and the detailed course of the rib profile of the respective separated cooling fin part are the result, however, which should be harmless for cooling and heat exchanger applications.

In the DE 10 2005 030 711 A1 is the use of paper honeycomb in furniture described. For producing the paper honeycomb it is stated that a characteristic wave is impressed by means of toothed and heated double rolls.

PRESENTATION OF THE INVENTION

The invention has for its object to produce at a web or a strip material of non-metallic and nichtwärmeleitendem material a wave-like or periodic profile shape whose desired shape or structure is achieved or maintained with optimized accuracy within the narrowest possible tolerances. The solution is made to the specified in claim 1 forming method and to the specified in the claim 11 forming arrangements. Optional, expedient refinements emerge from the dependent claims.

Accordingly, the forming means are arranged downstream of adjusting means which are designed to form-fit engagement in the previously embossed profile structure of the material web. Due to the form-fitting, it is possible for the adjusting means to intervene in the profiled material web for fine adjustment and / or correction of the profile structure in the sense of dimensional stability, to actively shift, hold or accelerate it and thereby stretch it or to compress. In particular, the period length of the profile structure can be changed, for example, if there is a deviation from the predetermined dimensional accuracy.

The modification of the period length is also an optional invention training, after which the forming and the adjustment means are changed or offset in their respective position or position relative to each other. In this context, it is expedient that the forming and the adjusting means are synchronized in their movements based on a common master axis, in particular a common position setpoint. This is either generated virtually, for example by means of ramp-function generator, or derived from a real axis, for example, by the movements of the forming means. This corresponds to an optional invention training, according to which the adjusting means are moved or actuated synchronously to the forming means, wherein adjusted for subsequent fine adjustment and / or correction of the profile structure for the purpose of setting, change or compliance with their dimensional stability, a relative phase position or a phase shift between the adjusting means and the forming or changed.

To set the relative phase position or the phase shift, the adjusting means (or the forming means) can be acted upon with corresponding control data or parameters, which are entered manually, for example, during ongoing forming operation. Alternatively or additionally, the adjustment or change of the phase position or phase shift of the adjusting means (or the forming means) by their regulation can be done depending on a measurement of the profile period length or other actual dimensions of the shaped profile structure. This opens the way to a further optional inventive concept, according to which the setting or changing of the period length of the profile structure in the context of a control loop with the measured profile period length or otherwise recorded dimensional accuracy of the shaped profile structure can be realized as an actual value.

If adjusting means are moved or actuated synchronously with respect to the forming means, then for the subsequent fine adjustment and / or correction of the profile structure for the purpose of setting, changing or maintaining its dimensional accuracy - alternatively or additionally in combination with the above Procedural steps - the spatial distance between the forming means and the adjusting means are set and changed. This can be done, for example, via a manual input from the distance setting serving drive control data or parameters, which correspond in particular to a desired influence and change the profile structure. Alternatively or additionally, a control of the distance between the forming and adjusting means depending on a measurement of the profile structure period length and / or other actual dimensions of the deformed profile can be operated for the profile structure dimensional stability.

To increase the dimensional accuracy of the reshaped profile structure, a rapid cooling is expedient after shaping. For this purpose, the use of one or more coolant is provided by an optional invention training, by means of which after profiling use at temporal and local distance thereof, the profiled material web is placed in a colder state. This, the formed profile structure stabilizing cooling can be conveniently combined with a previous heating of the web to promote their formability. Preheating may take place in a heating station located upstream of the forming means in the web transport direction. Alternatively or additionally, the or the forming means for the profiling contacting the material web can be heated. Preferably, the subsequent cooling and stabilizing of the material web profile structure takes place at the same time and place, or at least largely at the same time and location with the Verstellmittel-intervention or use instead.

A forming arrangement suitable for carrying out the forming process according to the invention is characterized in that one or more, complementarily profiled adjusting means follow the one or more forming means in the conveying or transport direction. These are designed for positive engagement in the profiled material web. In order to maintain the predetermined dimensional accuracy, the forming means are designed so adjustable that a subsequent fine adjustment and / or correction of the impressed by the forming or formed profile structure can take place.

The improvement of the deformability of the web serve heating means, which are arranged upstream of the forming and on the transport acting on the forming material web or strips act. Alternatively or additionally, the heating means may be in operative connection with the forming means or structurally integrated, so that their direct heating is possible. Further, preferably in combination with the heating means, one or more cooling elements or cooling elements for cooling the material web already profiled by the forming means are realized and arranged downstream of them. The cooling elements or cooling elements can be designed separately and are in operative connection with the adjusting means. Another possible realization is that the cooling elements are structurally integrated with the adjusting means, for example, by the adjustment means or include in addition to their actual adjustment function as a passive heat sink.

It is within the scope of the invention to realize the forming and / or adjusting each with a pair of opposing forming wheels (pairs of rollers), each having on the outer periphery a toothing or shape according to the einzuprägenden to be bent or otherwise shaped profile. Between them, a passage or conveying gap for the material web is limited. In fiction, specific development of this arrangement, wherein the form-wheel pairs are driven synchronized with each other, the adjustment form wheels is embossed relative to the upstream Umformrädern a positional / positional offset or a phase shift. The positional offset and / or the phase shift serve to maintain the predetermined dimensional accuracy of the profile or a corresponding correction.

In the context of the invention, the pairs of forming wheels are each set in rotation with one or more separate drives. To achieve the profile structure dimensional accuracy, it is expedient to rotate the forming wheel pairs, in particular the adjusting forming wheels, for example by means of servo drives to achieve a high degree of precision of movement. If the pairs of forming wheels or also the individual forming wheels are each coupled to a separate drive (single drive technology), these are preferably synchronized with one another via a jointly predefined conductance, for example position set value. Suitably, the master value or position setpoint is supplied via the corresponding setpoint input of the respective (servo) drive. In accordance with the invention, the production, restoration or adherence to the invention is Profile structure dimensional accuracy of the one or more drives of Verstellformräder-pair with respect to the upstream forming gear pair imprinted a positional offset or a phase shift. The positional offset or the phase shift can on the one hand via an open control ("open loop") for example by means of a manually operable input medium or other input interfaces are set or adjusted. On the other hand, it is possible to derive the position or phase offset (shift) to be impressed into the drives or servo-drives of the adjusting-forming-gear pair from a control loop with setpoint / actual value comparison and downstream control element. The actual value can be obtained from a measuring point for the period length or for other dimensional stability parameters of the reshaped profile structure. On the basis of the invention, it is expedient to monitor compliance or deviation from the predetermined profile dimensional accuracy by measuring the period length of the embossed profile structure. When evaluating and processing the measurement via control loop, the named measuring point is connected on the output side to the actual value input of a setpoint / actual value comparison element. This is a control element, for example, PI (= proportional-integral) controller, downstream for determining the einzuaufrägenden positional offset or einzuprägenden phase shift for the one or more drives of Verstellformräder-pair.

As an alternative to, in addition to or in combination with the aforementioned invention training (generation of a relative phase or phase shift between the adjustment and the forming means for fine adjustment and / or correction of the previously formed profile structure) is used to solve the above-mentioned invention task in an arrangement for Forming the profile shape of a material web with the features mentioned initially further proposed the following: The downstream, complementarily profiled adjusting means are provided or connected with one or more linear drives. These are set up and configured for adjusting the distance between the forming and the adjusting means such that, in order to maintain the predetermined dimensional accuracy via a change in distance, any subsequent fine adjustment and / or correction of the profile structure formed by the shaping means takes place. Thus, depending on the set or varied distance of the forming and adjusting a compression or Pull apart or a compression or elongation of the profiled strip material and thus achieve a fine adjustment and / or correction of the period length or other dimensional parameters of the embossed profile structure.

According to FIG. 1 an exemplary manufacturing process undergoes the manufacturing stations or steps listed as modules one through fifteen, with the modules utilizing nine "forming" and ten "cooling wheels" of the invention (see description in particular in connection with FIG FIGS. 7 and 8th ). With the module four "stripper unwinder" a rolling of coarse strip rolls with paper takes place. Two paper rolls are used to ensure continuous operation. The second roll is kept in reserve until the paper material of the first roll is used up. In module five "splicers", the end portion of one roll is welded to the beginning portion of the next roll. This is accomplished by means of an electromagnetically driven welding punch, whereby an optical sensor system for checking the presence of paper strips is also used. In the module six "buffer" is to ensure a continuous production operation, the time of splicing (interruption of the supply of material) compensated by a buffer. For this purpose paper strip rolls are kept ready on a mobile carrier. After completion of the splicing process, the memory is to be filled again. In the case of the module seven "slitters", a certain number of individual strips are produced from the supplied paper strips (for example, 80 mm wide strips into four strips each with a width of 20 mm).

According to FIG. 2 The module includes eight "preheating" a base 1 made of sheet metal and steel frame. On a multi-stage heater 2 is mounted with resistance heating elements 3, for example, each 300 watts. Within the heating device 2, preferably associated with one stage, a plurality of temperature sensors 4.1-4.4 are arranged. Of these, an infrared temperature sensor 4.4 is placed in the end portion of the heater 2. By this preheat module eight, the supplied material web, for example Paper strips, preheat in several stages to temperatures adjustable above the sensors 4.1-4-4, which facilitates subsequent forming.

For the module nine "transformation" according to FIG. 3 is located on the base 1, a drive unit 5, which has a plurality of drives, in particular each associated with a forming wheel drives 5a, 5b. In the pictorial representation, the forming wheels 6a, 6b are marked in each case via their protruding, solely visible shaft stubs or axle stubs. With them, the wave-like profile structure of the paper strips is generated. For this purpose, the respective outer circumference of the Umformräder 6a, 6b designed with a tooth structure corresponding to the desired profile structure. For better deformability, the forming wheels 6a, 6b are each heated separately. The deformation takes place under the action of a previously defined pressure (contact pressure), whereby the exposure time and temperature are also relevant for the quality of the material web. The mentioned process parameters are to be set depending on the respective material choice.

At the module ten "cooling" according to FIG. 4 is located on the undercarriage 1, a two cooling form wheels 7a, 7b superimposed drive unit 8, which each one of the cooling form wheels 7a, 7b associated drives 8a, 8b has. As in FIG. 4 indicated, the cooling form wheels 7a, 7b are provided on the outer circumference with a tooth structure corresponding to the upstream Umformräder 6a, 6b, so that for the cooling form wheels 7a, 7b a positive engagement complementary in the profile structure is possible, which of the upstream Umformrädern 6a, 6b was formed. As a result, the dimensional stability is stabilized or increased. This is also contributed to the cooling effect, which is exercised passively due to the mass and the preferably thermally conductive material (for example, metallic) of the (unheated) Kühlformräder 7a, 7b. In order to enable their positive engagement in the already formed profile structure of the conveyed material strip, the cooling forming wheels 7a, 7b are driven in synchronism with the forming wheels 6a, 6b (see below). If the cooling forming wheels 7a, 7b are offset in their phase relative to the forming wheels 6a, 6b, a Compression or stretching of the machined material strip in its length and also in its profile structure, especially in the period length effect.

For the module eleven "cross cutter" according to FIG. 5 is mounted on the base 1, a further drive unit 9, in which at least two drives, a drive 9a for a cutting wheel 10a, and a drive 9b are accommodated for an opposing counter-mold 10b. As in FIG. 1 indicated, in the material-belt conveying direction 20, the module "cross cutter" after the modules nine "transformation" and ten "cooling" arranged. The subsequent fine adjustment or correction of the profile structure formed by the forming wheels 6a, 6b by means of the cooling forming wheels 7a, 7b in terms of compliance with the dimensional accuracy is thus carried out before the transverse cutting or cutting the strip to a pre-defined length FIGS. 1 . 5 ,

In the module twelve "intermediate promotion", the cut strips are removed to a subsequent side turner. For this purpose, a conveyor belt is used, in the region preferably several, z. B. four optical sensors for the control of the honeycomb strips are arranged.

For the modules, thirteen "page turner" and fourteen "strip welder" according to FIG. 6 is on a frame 11, a drive unit for example, four honeycomb strip turner with corresponding drives together with guides 13 and a drive 14 for slide arranged. Further, a table top plate 15 placed on the frame 11 is associated with a position control device 16 for controlling the table top state. Furthermore, the table top 15 is in operative connection with means or drives 17 for raising and lowering. As soon as a cut, corrugated profiled paper strip gets into the page turner, it is turned by 90 °, the strip falls ("lying on its side") on the honeycomb table / welding table (table top 15). A slider positions the strips so that they are then welded by the strip sealer coming from below into a surface structure. The slider further conveys the honeycomb so that the next strips can be welded to the existing structure. The process parameters pressure, exposure time and Temperature is critical to honeycomb quality and depends on the material being processed.

According to FIG. 7 a material band 19 is conveyed in the transport direction 20 in the direction of transport 20 with a still smooth or even longitudinal profile in the gap of a pair of rollers, formed from the two opposite toothed forming wheels 6a, 6b. After forming in the nip, the material band 19 is provided with a running in sawtooth waves profile structure with the period length 21. In order to stabilize the longitudinal profile shape achieved, the now corrugated material strip 19a is fed to the nip of a second pair of rolls formed by the two opposing cooling forming wheels 7a, 7b. Both pairs of form wheels are each moved and controlled by a servo drive 22 which, as is known per se, is equipped as standard with a position, speed and current control for the respective electric drive motor. Each of the forming wheels 6a, 6b, 7a, 7b may each be assigned its own electric motor for rotary drive in the sense of a direct or single drive technology. Alternatively, the forming wheels can each be driven by a pair of rollers 6a, 6b and 7a, 7b mechanical couplings of a common electric motor. In order to realize between the two pairs of rollers 6a, 6b and 7a, 7b or between the Umformrädern 6a, 6b of the module nine and the Kühlformrädern 7a, 7b of the module ten for forming or cooling a DC or synchronous, is the two pairs of rollers 6a, 6b and 7a, 7b associated servo drives 22 given a common virtual master axis. This is realized with a position setpoint generator 23 which is guided by a ramp-function generator 24 in that the latter outputs a setpoint speed to the position setpoint generator 23. Thus, the cooling forming wheels 7a, 7b can run synchronously with the forming wheels 6a, 6b. The output of the position setpoint generator 23 is fed directly to the input of the servo drive intended for the forming roller pair 6a, 6b. At the input of the servo drive intended for the cooling-mold roller pair 7a, 7b, a phase shift (offset) 26a between the respective zero position of the forming wheels 6a, 6b and the cooling forming wheels 7a, 7b is superimposed on the output of the position setpoint generator 23. This can be realized for example by means of a summing element 25, the first input of the position setpoint, and the second input date or signal for the phase shift 26a from an input medium 26 is supplied. Due to the superimposition of the phase shift at the desired position value input of the servo drive, the cooling forming wheels 7a, 7b are given a phase offset or a lead or overfeed with respect to the forming wheels 6a, 6b, as in FIG FIG. 7 indicated by the positive and negative phase offset from the zero position. This correction or readjustment of the period length 21 or the dimensional stability by compression or elongation advantageously takes place in the production section between the forming roller pair 6a, 6b and the cooling forming roller pair 7a, resulting in a compression or elongation of the embossing wheels embossed profile structure. 7b, where the material band 19 with its profile due to the not yet (complete or noticeable) done cooling is still malleable. The compression or stretching process, which is still easy to implement, can be decisive for the dimensional accuracy of the profile structure. For compressing or stretching in the sense of a fine adjustment or correction to promote or maintain the dimensional accuracy of the form-fitting engagement of the cooling mold wheels contributes 7a, 7b in the formed by the forming wheels 6a, 6b profile structure. This upsetting or stretching and, concomitantly, the fine adjustment of the period length 21 of the profile structure can be influenced not only by the relative angular position between the forming and the cooling forming wheels, but also by the distance between the two pairs of rollers 6a, 6b and 7a, 7b. For example, the distance is several period lengths 21, in the example shown more than five period lengths. The phase shift overlay input medium 26 may be either manually operable or controlled by external product management software.

In the lower part of the FIG. 7 is for comparative clarification a synchronized angular position of the forming and the cooling molds each other drawn without offset. The respective angular position of the forming wheels of the two pairs of rollers 6a, 6b and 7a, 7b is identical.

In contrast to FIG. 7 is in the embodiment after FIG. 8 the phase shift generated by means of a closed loop 27. This has a PI controller 28 whose output is fed to the summer 25 with a positive sign (as in the input medium according to FIG. 7 ). The controller input is connected to the output of a setpoint / actual value comparator 29 connected. The first, positive input of the comparator 29 is supplied from the output of a profile structure Maßhaltigkeitsgenerators 30, a target value for the dimensional accuracy of the profile structure, analogous to the input medium according to FIG. 7 may be determined or influenced by manual input or by product management software. For example, the desired value may consist in a date or signal or other value for a desired period length for the profile structure to be impressed. The second, negative input of the comparator 29 is connected to the output of a measuring point 31 for the actual value of occurring after the cooling mold roller pair period length 21a of the profile structure. The measuring point 31 comprises a sensor 32 scanning the profile structure, in particular period length 21a of the deformed material strip 19. By detecting the actual dimensional accuracy of the embossed profile structure via this sensor 32 or the corresponding measuring point 31, the phase shift can be regulated via the control loop 27 and thus the quality of, for example, the paper strips to be reshaped for a honeycomb structure are decisively influenced. If a deviation of the actual period length 21a from the nominal period length is detected via the comparison element 29, the PI controller generates a corresponding phase shift 26a for the position or rotational position of the cooling form wheels 7a, 7b relative to the forming wheels 6a, 6b from the control deviation received , As a result, the deviation from the desired dimensional accuracy or desired period length of the profile structure can be compensated for via the stretching or compression resulting from the phase shift.
