Definitions
- the invention relates to a method and a system for position control of one or more webs, in particular paper-like or paperboard-like webs, which is preferably used in the production of corrugated board and corrugated board having a natural edge.
- Fig. 1 From the prior art plants for the production of corrugated cardboard are known, the basic structure in Fig. 1 is shown.
- Such a system comprises one or more unilateral groups in which a smooth and a corrugated web are joined together.
- the so assembled webs are called one-sided webs.
- the web When merging and laminating the one-sided webs and a cover sheet are merged into a single web and laminated. After lamination, the web passes through a heating and traction area. Here, the web is dried by the introduction of heat.
- the corrugated board web is trimmed at the edges and further cut into desired formats as required and transported to a warehouse.
- a device for detecting and / or controlling the edge position of paper webs in corrugator machines is known from DE 34 19 524 A1 known.
- Other devices are out US 4,288,273 and US 4,392,910 known.
- the present invention is therefore based on the object to improve the manufacturing accuracy.
- this object is achieved by a method, a system and a corrugated cardboard according to the independent claims of the invention.
- Advantageous embodiments are described in the dependent claims.
- a method for position control of one or more webs is provided, in particular paper-like or paperboard-like webs.
- Webs may preferably be understood here as paper or paperboard webs but may also be used, for example. Fabric panels, sheets of plastic and sheets of metal.
- a web may consist of one or more layers of the same or different materials.
- the method or the system according to the invention can be adapted for those types of webs which occur in the production of corrugated board.
- the term unilateral web refers to a web consisting of two layers of material, one smooth and the other wavy.
- the invention in one aspect, is concerned with optimizing the control of webs. Both in the production of a one-sided path, as well as in the merging of several one-sided tracks with a cover sheet, the best possible position control is desirable. The more accurately the webs can be positioned during assembly, especially relative to each other, the less scrap is generated.
- the invention detects first position information for one or more webs downstream of one or more position-influencing devices by first position-detecting means. Then, control of the web layer (s) is performed by using the downstream detected first attitude information by the attitude control device.
- the position of a web is used as a reference for controlling the other webs and a respective predetermined size indicates the desired relative position of the respective other web to the one web.
- the web center and / or one or both web edges can serve in the determination of the web layer.
- the web center is used to determine the web position and this aligned relative to the machine center.
- second position information for one or more tracks in the area of the position-influencing devices can be detected by second position detection means. This allows even more precise position control, as there is information about the location where regulation takes place and the location that can be influenced by the regulation. The dynamics of the web can thus be taken into account for its position control.
- the second position information in particular its change, can be used to control the position-influencing devices of one or more of the remaining tracks, in particular in order to reduce positional shifts of the tracks relative to each other.
- This allows not only a web to be controlled to a desired position without regard to the other webs, but also webs to be aligned with each other.
- the incorporation of the data obtained downstream can be dispensed with, as a result of which it is possible to realize a more cost-effective, albeit perhaps somewhat inaccurate regulation of the reference trajectory.
- the relative position of the webs to each other of outstanding importance.
- the second position information relates to the cover sheet to which the layers of the one or more other webs are regulated.
- the control can take into account the web speed and the distance that the web to be controlled has to cover between the position-influencing device and the position-determining device.
- the dead time can be incorporated into the control, whereby the control can be significantly improved in their accuracy.
- the detection of the first position information by first position detection means can be carried out in the region before the lamination, but behind a bridge, in particular in the region of the preheater or of the gluing unit or directly before the lamination.
- the position detection thus takes place behind the bridge on which the position-influencing means are arranged.
- position information downstream is detected only for one lane or for several lanes. The same applies to the regulation of the one or more position-influencing devices.
- a lane may be controlled either, or optionally, by information obtained downstream thereof, or information from one or more other lanes.
- the detection of the first position information by first position detection means in the region of the preheater and the detection of third position information by third position detection means in the region of the gluing unit can be undertaken.
- This information is available on at least two positions of one or more tracks, so that the dynamics of the system can be better taken into account. Consequently, both the first position information and the third position information can be used to control the position-influencing devices.
- the position-influencing devices are arranged upstream of the region of the preheater, in particular on the bridge.
- first position detection means are arranged in the region of the merger of two material layers, in particular in the region of a corrugating roller. Then, the position-influencing means or are preferably arranged upstream of a material layer heating and / or material layer moistening.
- the position of the two layers of material can be optimized for one another, in particular, that they are located centrally above one another or that the edges of one side lie one above the other. This in turn is important for working with natural edge.
- the control of the web layers preferably controls the position-influencing devices in such a way that the web layers lie flush over one another on one side, in particular in such a way that this side no longer has to be trimmed.
- optical sensors For position sensing means, optical sensors, cameras, CCD cameras, ultrasonic devices, or piezoelectric elements that work with ultrasound may be used.
- the invention is used in a corrugated papermaking plant, e.g. in corrugated cardboard plants with one to five one-sided groups.
- the web width of at least one web is measured at a plurality of positions in the course of the corrugated board production.
- a position detection means or a separate width measuring device can be used, depending on the respective measuring arrangement.
- the moisture of the web can be measured.
- the information obtained Width and humidity are used, for example, to determine a shrinkage factor, ie the ratio of one width to another width, for a specific production section or for the overall process. This information can be used to control humidification for greater process stability.
- conclusions can be drawn about the determined shrinkage factors on the quality of the base material used.
- a first web width and / or a first web moisture are measured after unwinding from a supply roll. At this point, the material still has its original width and moisture, it has not been moistened or connected to another track. Thus, the value determined here is used as a reference for the determination of a total shrinkage factor. Since it is possible to measure for each supply roll at such a location, it is advantageous to use the mean value of the widths or moistures thus measured.
- a second web width and / or a second web moisture can be measured, and in particular the first web widths and second web widths can be used to assess the accuracy of the joining.
- a web width and / or a web moisture can be measured prior to laminating and / or directly after laminating in front of the heating and drawing section and / or before the first trimming of the web. From this it is possible to determine, in sections, factors which can be used for the control of respective individual processes, such as wetting, drying or heating. From the measurement before the first trimming in combination with the measurements after unwinding, it is possible to calculate factors for the entire process, such as the shrinkage factor of the entire system.
- the web widths prior to lamination and the web width prior to the first trimming of the web are used to assess the accuracy of the assembly and / or overlay.
- Another aspect of the invention relates to a Georgia-to-vehicle system having a system shown above, inventive system.
- the plant for the production of corrugated board may further comprise one or more unilateral groups and / or a heating and traction area and / or a finishing.
- inventive principles can not only be used for the position control, but they can be used in an analogous manner for the web tension control. All aspects disclosed for attitude control in this specification or claims may be applied to web tension control.
- the position detection means are replaced by tension detecting means, in particular measuring rollers, or adjusted so that they can detect a web tension.
- the attitude control devices are replaced or adjusted to affect web tension.
- the invention detects first web tension information for one or more webs downstream of one or more web tension influencing devices by first web tension detection means. Then, control of the web tension (s) using the downstream detected first web tension information is made by the web tension influencing device.
- FIG. 2 shows a schematic representation of a one-sided group.
- a corrugated board manufacturing plant there may be one or more such unilateral groups. They are the same from their function and their basic structure.
- the paper or paper-like starting material is located on supply rolls 1.
- the supply rolls 1 are always arranged in pairs, wherein the material is unwound from one roll while the other roll is kept in reserve. If the material of a roll is exhausted, it is spliced at the point 2 on the other role, so that the supply of material does not break off. From there, the paper is passed into a first material store 3. Paper is stored here to compensate for the paper feed delay that occurs when splicing to a new roll. To regulate the memory contents in the memory 3, the deflection rollers on the right and left in the memory can be moved towards each other or removed from each other.
- the paper is guided past a width and / or moisture detection means 10 to the position-influencing device 4.
- the width and / or humidity detection means 10 detects the values of the paper web in its original state.
- the paper is passed after the attitude control device 4 over rollers, where it is heated, in particular with rollers, which are fed from the inside with hot water vapor.
- the paper is moistened on the way, so that it is more malleable and can be easier to connect two layers of paper later.
- a position detection means 7 and a width and / or moisture detection means 11 are arranged.
- the position detection means 7 detects the position of the two webs and / or their relative position to each other. This information can be used in various ways for the control of the Lübeein Wegungsvornchtungen 4. So she can e.g.
- a web is controlled to a predetermined position, wherein the other web is aligned relative to this first web.
- the web layers are regulated so that the edges of the two tracks on one side are exactly on top of each other.
- a width and / or moisture detection means 11 is also arranged in the region of the corrugating roller 5.
- the moistening of the respective web can be readjusted so that constant and controlled conditions prevail during gluing.
- the generated unilateral web is conveyed to the bridge 8.
- the so-called bridge stock 9 is arranged. He serves as a reserve for further production.
- the bridge supply 9 serves as a reserve, so that the manufacturing process can continue at a speed of about 100 to 400 meters per minute.
- the speed when producing the single-sided sheet is raised to an above-average value in order to replenish the bridge supply 9.
- a position detection means and / or width and / or moisture detection means 12 is arranged.
- further data for process monitoring and optimization are gained.
- information about the bridge supply can be obtained at the same time here.
- FIG. 3 shows a schematic representation of a merge, laminating and a heating and traction area.
- the position-influencing devices 15, 16 regulate the position of the single-sided webs as well as the required web tension.
- the cover layer is passed to the position control device 14 via a storage device.
- a width and / or moisture detection means can be arranged in front of the position-influencing device 14 in order to also detect the width of the cover sheet or its moisture.
- the webs are passed via a preheater 17 and a gluing unit 19 to the lamination 21, where the webs are joined together.
- the most accurate positioning of the webs to each other is desirable. Only when the webs are all glued together flush on one side, you can work with natural edge. Alternatively, all tracks can be aligned centrally with each other. critical is, however, that the position of the webs at the location of the lamination 21 is of the utmost importance, with the last position-influencing devices 14, 15, 16 still being placed in front of the pre-heater 17. For structural reasons, these can not be brought closer to the lamination. The last position control option is thus a whole distance from the lamination 21.
- the invention provides position detection means 18, 20, can be obtained by the information about the web layers in places that are much closer to the crucial laminating. It can be installed as needed only one of the position detection means 18, 20. Thus, e.g. only be measured after Glimtechnik 19 and not all tracks must be measured. The information obtained by the position detection means 18, 20 is used to control the attitude control devices 14, 15, 16.
- Each lane may be viewed separately and controlled to a particular position, with the deviation from this value, as measured by a position sensing means 18, 20, being used as the target value for the control of the attitude controllers 14, 15, 16.
- a web in particular the cover sheet, serve as a reference. Then the layers of the other webs are controlled relative to this.
- the information obtained for the reference trajectory can be used to control the other trajectories to track them or to compensate for the dynamics of the reference trajectory.
- position-influencing devices 4, 14, 15, 16 can themselves be equipped with position detection means.
- the distance the track has to travel between attitude control device 4, 14, 15, 16 and measurement location and the web speed is taken into account.
- damping can be set.
- width and / or moisture detection means can be used for the position detection devices 18, 20 additionally or alternatively. In this way, the desired moisture of the webs can be ensured in the lamination 21. In addition, all widths before the lamination 21 can be measured.
- the web After lamination 21, the web is dried in the heating and drawing area. Circulating belts pull the web through this area, while it is guided past heating elements. By introducing heat, the cardboard is deprived of moisture and dried.
- FIG. 4 is a schematic representation of a final processing. Behind the heating and traction region 22, a further width and / or moisture detection means 23 is arranged. The measured moisture is used to control the heat energy to be applied in the heating and drawing area 22. The measured width is used to determine a shrinkage factor along with the width values measured after unwinding for the entire manufacturing process. This gives information about the quality of the raw material used. In addition, the value measured here can also be used to evaluate, and possibly improve, the positioning of the liner 21. Thus, the cardboard web should not be significantly wider than the single webs at the point of measurement after the heating and traction region 22 the lamination 21. Furthermore, the shrinkage factor of the heating and traction region 22 can be determined.
- the web is forwarded to the first cropping 24.
- the edges of the web are trimmed or trimmed.
- the invention allows working with natural edge, in this case, the corrugated board must be trimmed only on one side.
- the system according to the invention does not have to be operated with a natural edge.
- the web is cut longitudinally and transversely to desired dimensions and passed into a warehouse, which on the right side of the FIG. 4 is shown schematically.
