Definitions

  • the invention relates to a machine for producing or processing a web of material, in particular a paper, cardboard or tissue web, with a press unit comprising a press roll and a counter press roll according to the preamble of claim 1.
  • Tissue paper machines have, for example, a press unit formed by a press roll and a counter press roll designed as a drying cylinder, in which the press roll is often pivotably mounted on a bearing lever relative to the counter press roll, so that the press roll is between an operating position by means of at least one adjustment unit acting on the mounting lever the press roll is pressed against the counter press roll, and is movable to an inoperative position in which the press roll is not pressed against the counter press roll.
  • the adjustment unit is designed as a hydraulic cylinder.
  • a tissue paper machine of this type is already known from EP 1 925 723 A1, which has a press unit comprising at least one press roller and a counter press roller, the press roller being mounted on a pivotable bearing lever and between an operating position in which the press roller is operated by means of at least one adjusting unit acting on the bearing lever is pressed against the counter press roll, and is movable to an inoperative position in which the press roll is not pressed against the counter press roll.
  • the known machine comprises an adjustment unit with a locking device by means of which the adjustment unit can be mechanically locked in the operating position.
  • the mechanical locking produced by the locking device can be released again in order to, at a later point in time, when the The press roller is pivoted back into the operating position to be restored.
  • EP 1 970 488 A1 also discloses a press arrangement with a press roller, which can be pivoted to and away from a counter roller via a lever pivotably mounted on a frame, the lever being adjustable between its pivoted position and its pivoted position via an adjusting device .
  • the press roller is connected to the lever via connecting elements, at least one of which is arranged such that when the lever assumes its pivoted position, it is vertically above the center of gravity of the press roller pivoted away from the counter roller.
  • EP 1 970 488 A1 also discloses that a self-pressing deflection compensation roller having an elastic jacket is formed with an inner jacket stroke.
  • the counter roll can be formed by a drying cylinder, in particular a Yankee drying cylinder.
  • the object of the present invention is to create a machine of the type mentioned at the outset, in which the above-mentioned disadvantages are eliminated, in which, on the one hand, the exact operating position of the press unit comprising a press roll and a counter-press roll is maintained, the press roll constantly on the Counter pressure roller is applied. A constant application of force to an adjustment unit is not necessary; At the same time, there is no need for a complex locking mechanism.
  • the press shoe is mounted within the shoe press roll on at least one soft, elastically resilient support element, which in turn is supported on at least one Yoke rests.
  • the pressure between the counter pressure roller and the press shoe can be controlled by means of the mounting lever.
  • the advantage of the invention is that a locking unit for actively pressing the press shoe against the counter roller, for example by means of a hose pressure or hydraulic piston, as provided in the prior art, is no longer required. Rather, the line force in the press nip or press nip with the counter roll can be continuously adjusted via the oil pressure of the hydraulic medium, i.e. H. Set the positioning lever in the hydraulic cylinders by controlling or regulating the pressing pressure in the press nip exclusively through the lever pressure. According to the invention, a constant application of force is therefore necessary.
  • the machine according to the invention for producing or processing a material web has a press unit comprising at least one press roll and a counter press roll, the press roll being mounted on a pivotable mounting lever and between an operating position in which the press roll is against the counter pressure roll by means of at least one adjustment unit acting on the mounting lever is pressed, and an inoperative position in which the press roller is not pressed against the counter press roller, is movable.
  • the use of an adjusting unit comprising a locking device by means of which the adjusting unit can be mechanically locked in the operating position, is avoided Drying cylinder, adjusts its oil pressure.
  • the use of a locking lever is avoided and the design of the press roller is simplified.
  • the operating positions can be flexibly adjusted, in which each of the press rollers and the counter press roller are each pressed against one another to different degrees. It goes without saying that the press roller can be swiveled away from the counter press roller for decommissioning or for carrying out maintenance measures.
  • the press shoe can be pressed against the contour of the counter roll, for example a Yankee cylinder, over the entire width with the same contact pressure in order to create the nip between the press shoe and the counter roll close.
  • the invention thus has a precise adaptation to the contour of the counter roll, which can change during operation due to the influence of temperature. Due to the flexible and soft structure of the support element, the pressure on the press shoe is continuously tracked and adjusted. In this way, according to the invention, uniformity of the contact pressure in the press nip is achieved over the entire width of the press roll, as cannot be achieved in the prior art.
  • the pressing system and the movement system of the shoe press are combined in one system.
  • No safety control or monitoring of the line force is required.
  • a shoe press roll controlled according to the invention can be treated like a conventional press roll, with press levers operated by actuators acting on the shoe press roll from the outside; the maximum line load is secured via the oil pressure in the actuators or hydraulic cylinders.
  • the simple construction of the shoe press roll without an internal adjustment mechanism saves costs.
  • the distance between the shoe press roll and the counter roll can be adjusted as required, while with internal sources of support, the stroke through the sleeve to one Distance of about 20 to 30 mm is limited. This small distance can lead to clothing damage when the counter roll is hot.
  • the press jacket and the press sleeve of the shoe press roll is made possible, while the jacket of the shoe press roll is bulged or deformed by the stroke of an active inner pressure system according to the prior art.
  • deformations in the contour of the counter roll for example the Yankee cylinder, which arise for example due to the temperature influence during operation, are compensated for by the elasticity of the support element. If the outer surface of the counter roll assumes a convex or concave shape during operation, this change in shape is compensated for by the corresponding deforming support element in such a way that the press shoe always rests against the counter roll with the same contact pressure in the press nip.
  • the pressing pressure is preferably regulated.
  • the humidity and / or the temperature of the material web can preferably be selected as a control variable for determining the pressing pressure.
  • a plurality of support elements arranged next to one another can be provided, which are preferably connected to one another.
  • Another advantage of the shoe press roll which can be pivoted according to the invention is that when the diameter of the counter roll, for example the Yankee cylinder, changes, there is no change in nip force.
  • the press pressure profile can be changed in the machine running direction and thus the drainage process can be optimized.
  • An embodiment for adjusting the press pressure profile is advantageous, according to which the shoe press roll has a rotatably mounted pressure shoe or a pressure shoe arranged in a flexible connection.
  • the shoe press roll has a plurality of individually mounted support elements. These can have different hardnesses, in particular at the two edges in edge zones, in order to improve the pressing of the press shoe against the counterpressure roller.
  • the counter pressure roller is preferably a Yankee cylinder.
  • the edge areas each have a width of less than 500 mm, preferably less than 300 mm.
  • the machine according to the invention is characterized in that the press unit is a double press unit and that the press roller mounted on the pivotable mounting lever is arranged as a second press roller in the direction of travel of the material web.
  • a dewatering element in particular a suction box or a suction turning roll, is arranged upstream of the second press roll in the web running direction of the material web.
  • the second press roller has a diameter of less than 1100 mm, in particular in the range between 700 mm and 1000 mm.
  • the second press roller particularly preferably has a diameter of not more than 750 mm.
  • the press unit comprising the counter press roller is arranged in front of the second press roller in the direction of travel of the material web by a first press roller designed as a suction press roller.
  • the second press roll is preferably designed as a shoe press roll.
  • drying cylinder in particular a Yankee drying cylinder, or a Yankee cylinder as the counter press roll.
  • FIG. 1 shows a schematic representation of a shoe press roll that can be used according to the invention and is in contact with a counter roll
  • FIG. 2 shows a shoe press roll which can be adjusted to another counter roll by means of a mounting lever and has a first press roll in front.
  • a shoe press roll 1 for use in a press section of a paper machine or other machine for processing a material web in a shoe press unit has a jacket 1 'with a very smooth paper-touched surface 1.1 and a less smooth shoe-touched inner surface 1.2.
  • the jacket 1 ‘runs around a shoe press unit, the press shoe 2 being supported by a yoke 3, while the jacket 1 ′ runs around the shoe 2 and the yoke 3.
  • a counter roller 4 is provided as a counter pressure element.
  • a material web 5, for example a paper web runs through the press nip and thus comes into contact with the very smooth outer surface 1.1 of the jacket 1 '.
  • a press felt 6 to be arranged between the material web 5 and the mating roller 4.
  • the inner side 1.2 of the jacket 1 is less smooth, that is, provided with a roughness> 10 mm.
  • the press shoe 2 is mounted on at least one flexible support element 7 extending transversely to the machine direction, which can be compressed in some areas so that it compensates for fluctuations in the outer diameter of the mating roll 4.
  • the shoe press roll 1 (FIG. 2) rests against a counter roll 8 during operation.
  • the material web 9 is guided, for example, over a first (not shown) felt strand or covering strand, while the material web 9 previously, ie over a first, first press roll lying against the counter cylinder 8 11, and up to the guide roller 10 via a second (also not shown) felt strand or covering strand.
