Definitions

  • the invention relates to a continuously operating press with a device for applying surface pressure according to the preamble of claim 1.
  • DE-OS 2 037 442 describes a press working with an endless belt and counter belt for the continuous production of shaped or pressed materials, which is characterized in that the belts are supported by a series of interacting rollers, each one around the direction of movement the belts are rotatable perpendicular axis and means for adjusting the gap between the two rows of rollers and / or for adjusting a force which biases the two rows of roller elements against a movement which pushes them apart, so that the two rows of roller elements on a between object lying in the endless bands can be set.
  • DE-AS 1 004 368 discloses a continuously operating belt press with at least one flexible, endless belt, preferably made of steel, which is used to transmit pressure to the material to be pressed, and with loose rolling elements which are closely lined up and used to transmit pressure, which is characterized in that that the rolling elements are provided with collar-like, cylindrical extensions and are offset in their longitudinal direction from each other by a collar division and are arranged in such a comb-like manner that they are at least close to one another with the end faces of the extensions.
  • DE-PS 2 157 746 describes a press for exerting a surface pressure on a longitudinal section of a leading web, in particular a press for the continuous production of chipboard and similar materials, in which the web runs along the width between endless, corresponding to the leading direction of the web the web of extending forming tapes is guided and in which rollers rolling between the forming tapes and a support structure provided above and below the web are provided in an endless sequence in the longitudinal plane perpendicular to the web, which transfer the working pressure from the support structure to the forming tapes, the rollers being divided into a plurality of rollers which are short in relation to the web width and, provided with their own guide means, are connected to one another like a chain.
  • roller chain arrangement is made up of many roller chains that are closely adjacent to the web and have independent widths that are independent of one another and have a constant width in the forward direction, each roller chain contains several rollers lying side by side, and the plates are arranged exclusively between them, and the joints containing the plates two adjacent rollers within each roller chain are laterally offset from each other in the forward direction.
  • the subject of CH-PS 327 433 is a device for the continuously progressive pressing of a plate-shaped material with two flexible endless belts which act as pressing surfaces and at the same time as conveyor belts.
  • the pressure on the back of the belts is transmitted by rolling elements made of round bars arranged in movable chains, the rolling elements being shortened with respect to the width of the pressing belts and being arranged offset with respect to one another.
  • DE-OS 2 853 285 relates to a device for applying surface pressure to progressive workpieces with at least one rotating press belt, which can be pressed against the workpiece by several similar rollers arranged in a row with parallel axes, the rollers being mounted in a stationary manner and on their sides facing away from the associated press belt are supported on rolling bodies designed as abutments, which is characterized in that two adjacent rollers are assigned to one or more rolling bodies arranged on a common axis.
  • DE-PS 27 35 142 describes a somewhat different approach to achieving a uniform pressure distribution.
  • an attempt was made to solve this problem by using a multilayer press belt arrangement which consist of several press belts of the same width and which are pushed into one another and matched in terms of their length and thickness to this purpose Thickness exists.
  • this multi-layer press belt arrangement can be supported by a stationary roller bed.
  • this patent specification does not provide any further details of how the roller bed should be designed.
  • FIG. 1 shows a view of the roller bed with continuous shafts seen from above
  • FIG. 2 shows a partial sectional view according to FIG. 1
  • FIG. 3 shows the lubrication of the rollers or rolling elements using a roller bed with divided shafts.
  • the roller bed shown in Fig. 1 is used to apply a surface pressure in a continuously operating press.
  • This continuously operating press is designed as a double belt press and has two double belt units one above the other.
  • Each double belt unit consists of a multilayer belt arrangement guided over a pair of deflection rollers. Between the lower run of the upper multilayer belt arrangement and the upper run of the lower multilayer belt arrangement, the material to be pressed is continuously passed through the double belt press and thereby exposed to the pressing pressure.
  • the pressing pressure exerted in the pressing area of the double belt press is transferred to the upper multilayer belt arrangement from an upper support plate 6 and to the lower multilayer belt arrangement from a lower support plate 6 by means of the rollers 2 of the stationary roller bed to the respective multilayer belt arrangement.
  • the roller bed has a frame-like support body or a support plate 6, in which bearing strips 4 running in the longitudinal direction of the double belt press are attached, with two limiting strips 5 running in the transverse direction at the ends of the support plate 6.
  • the bearing strips 4 are traversed by continuous shafts 1 running in the transverse direction of the double belt press.
  • Rollers 2 mounted on bearing needles 3 are arranged on the shafts between the bearing strips 4.
  • the rollers 2 are offset from one another in rows. As can be seen in FIG. 3, the length of the bearing needles 3 is the same as the length of the rollers 2.
  • roller bed which has split shafts 1.
  • two adjacent bearing strips 4 are traversed by a shaft 1 running in the transverse direction of the double belt press.
  • a single roller 2 is mounted on bearing needles 3.
  • the shafts 1 with the rollers 2 are in turn arranged offset.
  • the bearing needles 3 in turn have the length of the rollers 2.
  • the rows of staggered arrangement of the rollers or rolling elements 2 running on bearing needles 3 on continuous or divided shafts 1 and bearing strips 4 arranged between each row of rollers achieve a particular strength, in particular good bending strength, of the roller bed, which enables this to exert a particularly uniformly distributed surface pressure , a fact which, despite all the different possibilities available according to the state of the art, has so far not been achieved to this extent.
  • the rollers 2 have a spherical, barrel-shaped shape on the outer surface, which corresponds precisely to the course of the bending line of the roller with its largest diameter, which is understood as a carrier with surface load supported multilayer belt arrangement corresponds. Then there is the same Hertzian pressure everywhere along the line of contact in the transverse direction of the double belt press between the barrel-shaped roll and the multi-layer belt arrangement and destructive changes in tension in the multi-layer belt arrangement are largely avoided.
  • seals made of elastomeric materials are arranged in the rollers 2, which seal against the bearing strips 4 sliding.
  • These seals preferably consist of O-rings 8 inserted in the grooves of the rollers 2.
  • the space of the roller bed in which the bearing needles 3 are mounted is sealed to the outside and forms a rolling element filling space which is located between the shafts 1, the O-rings 8, the bearing strips 4 and the rollers 2 extends.
  • This rolling element filling chamber is filled with lubricant.
  • In the bearing strips 4 there are bores or other connecting cavities between the rolling element filling spaces, so that forced circulation lubrication of the rolling surfaces is possible and a constant supply of the rolling elements 2 arranged in the individual rows is ensured with lubricant.
