Definitions
- the invention relates to a device for aligning rotationally controlled elements, such as rollers or shafts, for which an exactly synchronous run is desired, as well as a corresponding pair of rollers.
- a device for aligning rotationally controlled elements, such as rollers or shafts, for which an exactly synchronous run is desired, as well as a corresponding pair of rollers.
- Such a device is necessary, for example, for embossing applications using a pair of rollers, in which a first roller carries a positive engraving (male) and a second roller a negative engraving (female).
- To prevent damage to the rollers, or to achieve a high-quality and reproducible embossing result must be able to ensure that the rollers are set radially and axially in exactly predetermined position to each other. This includes the presetting of the distance of the rollers to each other, the so-called embossing gap to give the material to be embossed the desired embossing height, but not too strong to emboss the
- DE 101 11 025 A1 discloses a method for contactless adjustment of the nip and the embossing rollers used for this purpose.
- the described method requires that for the axial alignment of the embossing roller pair each embossing roll is provided with at least one mark, which is arranged on the lateral surface of the embossing roll and whose position is aligned relative to the present on the surface engraving.
- at least one end face of each embossing roller is provided with at least one further marking, the position of the further marking being aligned relative to the engraving present on the surface of this embossing roller.
- the adjustment of the pair of rollers takes place in that the two embossing rollers while maintaining the parallelism of their lateral surfaces and while avoiding contact between the lateral surfaces are moved relative to each other until all of the above-described markings on the first and second embossing rollers are aligned with each other and until a predetermined nip is set.
- the above-described method for adjusting the nip requires that at least one marking is provided on the lateral surface as well as on an end face of both rollers. Preferably, at least two markings are even on the lateral surface of each embossing roller, wherein the alignment is effected in that each pair of associated marker pairs are aligned.
- the latter step is carried out via an optical detection of the markings and a connected image processing method.
- the devices known from the prior art thus have the disadvantage that a plurality of markings is necessary in order to achieve the necessary precision for the reliable operation in the alignment of the roller pair. Furthermore, the known devices each provide at least one marking both on the roll shell surface, as well as on at least one of the end faces in order to achieve the desired orientation of the roller pair in both the axial and radial directions. This requires in the Rule that at least two scanning devices are necessary, one for reading the mark on the lateral surface and one for reading the mark on one of the end faces. In addition, the necessary image processing and evaluation brings increased data processing costs.
- the device according to the invention is intended to provide only a minimum down payment markings and readout devices while ensuring the adjustment precision necessary for operation.
- Protection claim 8 defines a device for adjusting a roller pair, using the roller pair according to the invention.
- Advantageous embodiments are the subject of the dependent claims.
- At least one of the rollers has at least two markings on the lateral surface of the roller, of which two markings between each an expansion enclose an angle ⁇ , with 0 ⁇ ⁇ 90 °.
- the markings are arranged in dependence on the embossing pattern, so that after the detection of the markings with the required accuracy on the axial and the radial position of the respective roller can be closed.
- Each mark has at least two extents when engraved, three.
- one extension represents the engraving depth, while the other two extensions extend over the lateral surface of the respective roller.
- the named expansions run parallel to the symmetry axes of the respective marking.
- Reference marks are engraved simultaneously with the embossing engraving in a clamping in the roll surface, whereby the exact positioning is ensured relative to the embossing engraving. Another advantage of the fact that all markings lie on the lateral surface is that it is thus also possible to read them out or to detect them by means of a single measuring unit.
- At least one marking has an edge extending at least in sections parallel to the roll axis.
- non-contact means such as light barriers, lasers, ultrasonic sensors, inductive sensors or air sensors. The associated increased working distance between sensors and embossing rollers causes a lower risk of contamination in the embossing operation.
- the two markings can be present directly next to each other, which also allows fast readout of both markings, but they can also be further spaced apart.
- the detection of the markings with the aid of the aforementioned means is based on the evaluation of the contrast of the reflected measuring signal, which increases when the measuring signal impinges on the mark when the roller rotates over the boundary. In general, this is associated with the fact that the reflected signal, at least briefly, has a significant intensity fluctuation. Therefore, when measuring markings according to the invention, their width and depth are not relevant, since the measurement takes place only via the detection of the edge and the associated measurement signal reflection gradient. In the preferred embossed mark embodiment, coloring of the mark is not required to achieve optical contrast. Furthermore, in the case of a roller pair according to the invention, the use of an imaging measuring system is likewise not necessary. The detection of engraved markings in the form of milling Th grooves on a laser measuring method, but also in this case a laser sensor image processing is not required.
- the device for adjusting a pair of rollers has at least one scanning unit, at least one setting unit and at least one evaluation and control unit.
- the scanning unit allows the contactless scanning of the markings on at least one roller by means of one of the aforementioned means, each scanning unit being designed to scan all markings of exactly one roller.
- the setting unit is used to align at least one of the clamped rollers at least in the axial and radial directions.
- the evaluation and control unit initially determines the position of the rollers in the axial and radial directions from the measuring signals of the scanning units. According to the determined result, it then sends a control signal to the actuator to act on the respective roller corrective.
- the apparatus described above uses rollers, both of which each have two markings.
- Such a device then has two scanning units and two actuators, each actuator is associated with exactly one roller.
- Such a device makes it possible to determine the exact alignment of both rolls independently of each other and to set them each separately according to the particular orientation separately from each other.
- the rollers are usually aligned completely unoriented, which also means that the applied marks are not located directly in an area where they can be read by the provided scanning unit.
- the evaluation and control unit of an expedient embodiment is preset in such a way that it rotates the rollers before the actual approach and orientation to one another until an evaluation of all markings has taken place.
- the evaluation and control unit It has proven to be expedient for the evaluation and control unit to carry out a plausibility check by repeatedly determining the relative orientation of the two rolls in the axial direction during the setting process as well as during normal operation of the roll pair with repeated use of the measuring signals of the scanning units and radial direction to each other and optionally sends a corrective control signal to the actuators.
- This active control of the roll orientations is also possible during ongoing production, and thus prevents misalignments that reduce the quality of the embossing result, or even lead to an impairment of the pair of rollers.
- an embodiment of the device according to the invention additionally has a hydraulic bearing air adjustment of the radial embossing roller bearing for vibration reduction of the embossing rollers.
- the bearing air adjustment takes place via the temperature monitoring of the individual bearing points.
- Figure 1 is a perspective view of a device according to the invention using a pair of rollers according to the invention.
- FIG. 1 shows a roller pair 3 according to the invention, in which each of the rollers has a pair of markings 1.
- the markings are each arranged in the axial direction at the edge of the first and second rollers 3 on the lateral surface thereof. This allows the simple scanning of the marks 1 by means of the first and second scanning unit 2, which is arranged at a distance which is largely arbitrary, to the roller surface and thus to the markers 1.
- the contactless scanning of the markings 1 takes place by means of a laser beam 4.
- either the markings 1 or the angled marks 1 running parallel to the roll axes are first detected.
- the markings 1 running parallel to the roll axes would first be detected, so that at constant angular velocity of the rolls 3, first of all the time offset between the detection of the mark 1 extending parallel to the roll axis on the first roll 3 and the corresponding marking.
- tion 1 on the second roller 3 with the aid of the scanning units 2 affiliated evaluation and control units on the necessary influence of the provided for aligning the rollers 3 actuators to achieve the desired synchronous operation can be concluded.
- the position of the corresponding roller 3 in the axial direction can again be deduced from the time offset between the detection of the marking 1 running parallel to the roller axis and the detection of the angled marking 1 on the same roller 3 in order to carry out corresponding readjustment measures with the aid of the evaluation and control unit in cooperation with the corresponding setting unit.
- the detections of the marking edges of both markings which initially overflow in the direction of rotation, are preferably decisive for determining the time offsets mentioned above.
