Definitions

  • the invention relates to a calender for the production of sealing plates, which has a motor-driven heating roller of large diameter, which is mounted in non-displaceable bearings, and an unheated pressure roller of smaller diameter, which is mounted against a pressing force in displaceable bearings and is driven by a separate motor.
  • So-called sealing plate calenders which have a heated roller on which the plates are rolled and vulcanized, and a cooled roller, which serves as a pressure roller for the assembly, are used for the production of fiber-reinforced flat seals, which are required at numerous points in technology is usually pressed hydraulically.
  • the seals are made from a mixture of rubber-coated fibers and fibers, which give the strength of the finished product.
  • asbestos fibers have been used as reinforcements, since the manufacture and use of panels excluded other fibers for thermal reasons. asbestos is increasingly undesirable due to health hazards and has recently been replaced, if possible, with new high-strength and thermally resistant synthetic fibers.
  • processors such as are known in a computer-controlled laboratory measuring roll mill that has become known from the journal Kunststoffe 74 (1984, p. 654)
  • processors which are used in the automation of calender lines in the rubber industry to control the processing machines arranged in front of the calender and behind the calender.
  • the present invention avoids the disadvantages of the prior art and enables the manufacturing technique of sealing plates to improve drastically and thus create the conditions for the processing of fibers that are a replacement of asbestos fibers. It is the object of the invention to create a possibility of tracking the roller circumferential speed by means of permanent measurement of the build-up of the plate thickness, both for an exact synchronization of the roller circumferences and for a specific, controllable friction.
  • the invention is that the two drive motors of the two rollers are controlled by a program-controlled processor, at one input a displacement sensor for the displacement of the axis or the axle bearing of the pressure roller, at the second input a sensor for determining the passage of the Heating roller or its drive shaft attached marks, at the third input an encoder for determining the passage of marks attached to the pressure roller or its drive shaft, and at its two Outputs control devices for the speed of the two motors for the roller drive are connected.
  • a program-controlled processor at one input a displacement sensor for the displacement of the axis or the axle bearing of the pressure roller, at the second input a sensor for determining the passage of the Heating roller or its drive shaft attached marks, at the third input an encoder for determining the passage of marks attached to the pressure roller or its drive shaft, and at its two Outputs control devices for the speed of the two motors for the roller drive are connected.
  • the two motors can be used for an exact measurement of the roller circumferential speeds by measuring the time interval of the appearance of the marks arranged on the circumference of the rollers and by an exact measurement of the plate thickness, which is carried out by the displacement sensors for the displacement of the axis or the axis bearing of the pressure roller adjust the drive of the two rollers to exactly the same peripheral speeds despite the increasing diameter of the heating roller because of the increasing thickness of the stacked plate.
  • friction can also be achieved for the entire running time as well as for certain times of the running time or for certain thickness sections of the plate by a certain delay in the drive speed or an increase in the drive speed compared to the synchronous speed of the pressure roller.
  • non-processable fibers can be incorporated into the sealing plates on conventional calenders, and completely new qualities of sealing plates can also be produced, which take place through the friction run during certain, not all, phases of the construction of the sealing plate.
  • the sensors actuated by the marks on the rollers are incremental sensors.
  • buttons for scanning the surface of the plate built up on the heating roller which are connected to a further input of the processor.
  • the shaft 10 of the heating roller 2 and the shaft 11 of the pressure roller 3 are mounted in the stands 1 of the calender.
  • a DC motor 12 drives the shaft 10 of the heating roller 2 and a DC motor 13 drives the shaft 11 of the pressure roller 3.
  • the shaft 11 of the pressure roller 3 is slidably mounted in the calender stand 1, the shaft 11 is pressed in the direction of the shaft 10 by a hydraulically generated force.
  • the location of the shaft 11 is dependent on the thickness of the sealing plate 14 built up on the heating roller 2.
  • the position of the shaft 11 of the pressure roller 3 is determined by an encoder 15.
  • the heating roller 2 is provided on its circumference with marks 16 arranged at the same distance.
  • a sensor 17 is provided, which emits a pulse each time a mark 16 passes, which is fed to the input 5 of the processor 9.
  • marks 18 are attached to the pressure roller 3, the passage of which is sensed by an encoder 19 which is connected to the input 4 of the processor 9.
  • the third input 6 of the processor 9 is connected to the encoder 15.
  • the processor has two outputs 7 and 8, of which one output 7 is connected to the control device 20 for the motor 13 and the other output 8 to the control device 21 for the motor 12.
  • buttons 22 for scanning the surface of the plate 14 built on the heating roller 2 which are connected to a further input 23 of the processor 9.
