Definitions

  • the invention relates to a device for controlling a calender for the production of sealing plates, which is equipped with a heating roller of large diameter and a separately motor-driven counter-pressure roller of smaller diameter, with two plate thickness measuring transducers, a rotational speed sensor, revolution counters, as well as engine speed regulators and pressing force generators and counter bending force generators.
  • 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 and fibers made processable in solvents, which give the strength of the finished product, produced.
  • Asbestos fibers have traditionally been used as reinforcement, since the manufacture and use of the panels excluded other fibers for thermal reasons.
  • asbestos is increasingly undesirable due to health hazards and has recently been replaced, if possible, with high-strength and thermally resistant synthetic fibers.
  • the invention avoids the disadvantages of the prior art.
  • the invention has for its object to provide conditions for the proper control of the manufacturing process of synthetic fiber reinforced sealing plates, in which a consistently high quality of the sealing plates produced is achieved.
  • the invention achieves this in that the operator has left the machine and process control that has been generally customary up to now and is switched to automatic process control.
  • a computer program is developed which takes into account all the parameters mentioned and thereby enables the operator to concentrate on the monitoring of the system and its optimal loading with mass and merely to monitor the other entire manufacturing process.
  • the processor is connected to temperature sensors for the surface temperature is connected to the plate being manufactured and a circuit is provided for linking the functions of the process specifications as a function of the surface temperature. Because the surface temperature gives a special indication of the solvent content of the applied layer and the degree of vulcanization.
  • 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, by means of a force generated by the hydraulic pressing device 24, the shaft 11 is pressed in the direction of the shaft 10.
  • 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, each of which passes when one passes Mark 16 emits a pulse 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.
  • Pipes 26 lead from the heating device 25 into the heating roller 2.
  • a temperature sensor 27 is arranged in these pipes, the output signals of which are introduced into the input 28 of the processor 9.
  • the pressure roller 3 is connected to the cooling device 30 via pipes 29.
  • a temperature sensor 31 arranged in the tubes 29 is connected to the input 32 of the processor 9. From the output 33 a control line leads to the heating device 25, from the output 34 of the processor 9 a control line leads to the cooling device 30.
  • Another output 35 of the processor 9 leads to the control device 36 of the hydraulic pressing device 24 on the pressure roller 3. From the output 37 of the processor 9, a control line leads to the control device 38 of the counter-bending device 39.
  • a loading device 40 is arranged, which is connected to the output 41 of the processor 9.
  • a device for the solvent supply 42 is provided, the solvent flow of which is controlled by the control device 43, which is connected to the output 44 of the processor. Furthermore, a material distribution device 45 is provided, the control of which is connected to the output 46 of the processor.
  • Various memories 47 in which recipes and / or procedures are recorded, are connected to the input 49 of the processor 9 via the selection device 48.
  • the output 50 of the processor which leads to the memory 47, is provided for the recording of programs according to a manually performed control.
