Definitions

  • the invention relates to a method for processing pelletizable material in a pelleting press equipped with a punch die and one or more paners.
  • B. hydraulically driven adjusting devices with associated position measuring devices, can be set to a predetermined distance from the surface of the punch die.
  • rollers do not have their own drive and accordingly roll with more or less slip compared to the driven die.
  • DE-OS 38 16 842 has made known, in addition to the ring die, to drive the press roller (s) in the same direction as this.
  • the press rollers have been rigidly connected to the support shaft, the support shaft rotatably mounted and connected to the drive of the ring die via a toothed belt.
  • this toothed belt is placed so that each of the bearing axles of the press rollers is driven accordingly.
  • Commercially available tensioning devices complement these toothed belt drives.
  • a hand lever is provided for adjusting the distance between the ring die and the press roller, which enables the roller to be adjusted when the press is empty.
  • the design results in a rigid coupling of the speeds of the die and the press roll, regardless of the distance of the roller from the die.
  • An adaptation to the speed changes necessary due to wear or different material film thickness is just as impossible as an adaptation of the size of a desired slip depending on the material to be pressed.
  • WO 91/02644 describes a pelleting press in which both the roller and the ring die can be driven independently of one another at variable speeds.
  • the mounting of the die and / or the Koller are designed such that the distance between the Koller and the ring die, that is, the gap width between the Koller and the die is adjustable.
  • the shear stresses in the material to be pressed on the surfaces of the roller and die should be approximately the same. These shear stresses are then the same, it is assumed in this proposal if the forces acting on the roller correspond approximately to those acting on the die.
  • the torques or the power consumption at the roller drive and the die drive based on their diameter, are used. The torque can be determined via the power of the drives or e.g. via torque measurements on drive shafts.
  • the known solution proposal takes into account the wear on the die and Koller not. Due to the reduction in the diameter of the roller, with simultaneous increase in the diameter of the die due to wear, there are undetectable differences in the necessary consideration of the diameter for controlling the drive speed as a function of the drive torque.
  • the invention is based on the problem of equipping a press in such a way that, on the one hand, it enables a smooth and even pressing process under all operating conditions, that even good pressing conditions can be set even in the event of changes due to operational material wear and that the press parameters, including the die speed and the layer thickness of the material to be pressed, depend on the material can be adjusted.
  • this is achieved with a method using the specified machine requirement in that the rollers are applied to the driven punch die by the adjusting device for frictional engagement when the press is empty and this position of the roller detected by the position measuring device is fed as a control variable together with the roller speed detected thereby to a computer which controls a roller drive during load operation via a speed control device in such a way that the peripheral speed of the roller surface as a function of the roller position, in each case the peripheral speed of the facing surface corresponds to the punch die, possibly with a predeterminable slip between the Koller and die.
  • the roller speed can be directly adapted to the change in the distance between the die and the roller, i.e. to the layer thickness, using a simple calculation process.
  • Fig. 1 shows a side view of a pelleting press according to the invention in a schematic representation, partly in section, showing the drive and the storage of the Koller.
  • Fig. 2 shows the same press as Fig. 1, wherein instead of the Koller, the material feed is shown.
  • Fig. 3 shows in elevation along the line III - III, in a schematic representation, the ring die with the spatial assignment of roller drive and material supply.
  • the brackets 2, 4 and the holder 3 are placed on a base frame 1 at an angle-resistant manner.
  • the support bracket 2 is mounted on the base frame 1 with the slide bearing 5 switched in such a way that the press for exchanging the die 12 can be opened and closed by a longitudinal movement on this slide bearing 5.
  • the support bracket 2 holds the Support shaft 6 on which the die holder 8 is rotatably mounted via the roller bearings 7.
  • the drive motor 9 is also attached, which drives the ring die 12 with the holes 13 via its pulley 10 and the pulley 11 of the die carrier 8.
  • the holder 3 On the base frame 1, the holder 3 is fixed angularly and rigidly on the side of the press remote from the support beam 2. This holder 3 carries with extensions 14, 15 and 16, the bearings 17 for the shafts 18, the roller 19 and the roller drive 20 together with the gear 21.
  • the material feeds each consist of a receiving funnel 22, from which the material to be pelletized is fed via a transport check 23 to the interior of the ring die 12 via the openings 24.
  • the pellets coming from the press are discharged to transport or packaging devices.
  • the drive 9 for the ring die 12 is switched on when the press is empty.
  • the roller 19 is then moved against the running ring die 12 and thus brought into frictional engagement by means of an adjusting device (not shown) which is known per se.
  • the detected speed of the pan and the die as well as the spatial position of the pan and its axis are then recorded in a computer and the distance between the die and the pan desired for the pelletized material is then entered.
  • the computer now outputs the values for the speed of the roller from the measurements and the specifications as a control command to the roller drive.
  • the control of the roller drive can be carried out with all known means.
  • a frequency converter can be used Output frequency determines the speed of the motor for the roller drive.
  • a controllable torque converter can also be used together with an electric motor which is constant in terms of its speed, optionally together with a reduction gear. Purely hydraulic drives can also be used if the equipment is suitable for speed control.
  • a desired slip between the die and the Koller can also contribute to improvements in the product, as well as lower energy consumption, by means of appropriate specifications in the control system
  • each of the rollers used is assigned its own controllable drive, then locally different compressions and the like can also be controlled by the speed control.
