Definitions

  • the present invention concerns devices for checking paper quality control parameters during the production cycle, and in particular it concerns a new system for adjusting and controlling the water content in paper in the transverse direction with respect to the forming direction during the production cycle.
  • Said formation wire slides so that the liquid compound spread on it passes through various processing stations, where it is progressively dehydrated due to the effect of gravity only and/or due to the action of vacuum sucking devices.
  • the paper web has a content of dry material that ranges from 15 to 20%.
  • drying the sheet further means using considerable energy.
  • heat energy is employed, in the form of vapour or infrared radiation.
  • Said scanner employs radiation emitters and, by means of an apposite correlation algorithm, determines said grammage starting from the evaluation of the intensity extinction of said radiations.
  • the presence of some more or less humid areas can be due for example to the non-homogeneous distribution of the compound during the formation step, or to particular conditions in the setting up of the system.
  • the humidity control system works retroactively, causing a variation in the heat energy introduced upstream of the system in order to obtain the evaporation of water.
  • This system is rather effective in the control of the water content in the longitudinal direction with respect to the production line.
  • This gradient is a function of the total thickness of the paper web and of the possible use of technological-functional aids employed in the production cycle.
  • Another object of the present invention is to minimize the humidity gradient between the surface layers and the inner layers of the paper web, by means of microwave dehumidifying devices that effectively act on the innermost part of the web thickness, differently from the systems currently used.
  • Another object of the present invention is to ensure reduced treatment times, particularly in relation to the feeding speed of the paper web in the production line.
  • the new system for adjusting and controlling at least the water content in paper during the production cycle comprising one or more dehumidifying devices that emit microwaves at controlled frequency, connected to at least one device suited to measure and determine the paper humidity profile along at least one given cross section, said cross section being preferably located downstream of the production line and of said microwave emitting devices.
  • Said measuring device thus acts retroactively, determining the humidity content profile of a cross section downstream of the production line.
  • the data referring to said humidity profile are processed by an electronic unit that communicates with said microwave emitting devices positioned upstream, activating or deactivating them and/or adjusting their power so that they have effect only on the areas with humidity peaks above the reference value or outside a reference interval.
  • Said microwave emitting devices are preferably installed on a head and are suited to act on all the points of a cross section located upstream of said cross section where the measurement has been carried out.
  • said head can be a mobile head, travelling crosswise with respect to the direction of the production line, in such a way as to position said microwave emitting devices exactly at the height of the paper portion to be dehumidified, according to the humidity profile given by said measuring device.
  • said head may occupy an entire cross section, and said microwave emitting devices can be distributed in such a way as to affect the whole cross section and to be activated alternately or simultaneously in order to act on some specific areas, according to the humidity profile given by said measuring device.
  • the main advantage offered by the new control system lies in that it makes use of said dehumidifying devices that emit microwaves and are suited to make the water contained in the paper evaporate starting from the innermost layers, thus obtaining also the normalization of the humidity gradient through the thickness of the paper web.
  • the surface layers of paper will not be drier than the inner layers, as is the case when the known drying systems, for example the drying cylinders, are used.
  • microwave emitters guarantees higher precision of the paper dehumidifying treatment, since even very narrow or very wide areas can be treated.
  • the action of the microwave emitting devices is very rapid, in fact said devices can be activated and deactivated instantaneously and operate rather quickly, differently from the known dehumidifying devices that on the contrary do not have the same effects in the required time as dictated by the paper feeding speed, considering also the heat insulation effect exerted by the paper surface layers.
  • the paper (F) produced in webs by pouring on a surface a given quantity of liquid compound consisting of water and cellulose fibre, slides in a direction (X), or direction of the production line, and passes through various stations, where it is progressively dehydrated so that the dry material passes from the initial value of 0.4-1% to an optimal value of 40-50%.
  • the new system for adjusting and controlling the water content comprises one or more dehumidifying devices (M) that emit microwaves at controlled frequency, suited to treat at least one area of the paper web (F).
  • M dehumidifying devices
  • said dehumidifying devices (M) are installed on a head (T) in such a way as to allow the paper (F) to be treated alternately or simultaneously on all the points of said section (F1).
  • said head (T) can move and travel crosswise (Y) with respect to the direction (X) of the production line, in such a way as to position one or more of said microwave emitting devices (M) along said section (F1) only at the level of the portion of paper (F) to be treated.
  • said head (T) may occupy the whole section (F1) of the paper web (F) and said microwave emitting devices (M) may be distributed in such a way as to occupy the whole section (F1), too.
  • Said microwave emitting devices (M) can thus be activated alternately or simultaneously so that they act only on some given portions of said section (F1) of the paper web (F).
  • Said measuring device (C) thus operates retroactively, determining the humidity profile (P) of a measurement section (F2) located downstream of the section (F1) where the dehumidifying treatment is carried out with respect to the direction (X) of the production line.
  • the new adjusting and controlling system also comprises at least one electronic unit (S) that receives from said measuring device (C) the data concerning said humidity profile (P), processes them and, through a PLC control unit (R) of said microwave emitting devices (M), activates or deactivates one or more of said microwave emitting devices (M) so that they operate in a focused manner only on some portions (Fx) of the paper web (F).
  • Said measuring device (C) being positioned downstream of said microwave emitting devices (Mx) and therefore of said dehumidified band (Fx), continues measuring said humidity profile (P) and, according to the measured values, deactivates said microwave emitting devices (Mx) or modifies their power so that the paper (F) is correctly dehumidified.
