Definitions

  • the invention relates to a device for wrapping a stack of goods with a stretched film, with a satellite encircling the stack of goods and supported in a frame, which carries a film roll and at least one braked deflection roller.
  • the satellite is arranged under a disc, which is rotatable about a vertical axis and is mounted on the transmission and can be moved up and down in a frame. So that the film can be stretched around the stack of goods after it has been pulled off the film roll, it is guided over at least one deflection roller which is electrically braked.
  • the electrical energy and control cables are routed over slip rings. Slip rings are technically complex, prone to failure and wear out quickly. Therefore, it also makes it difficult to use the required braking energy when starting Way to dose.
  • the object of the invention is to dispense with slip rings in a generic device.
  • a brake the braking force of which is derived from the rotary movement of the satellite and / or the deflection roller.
  • a brake actuated by the centrifugal force of the satellite and / or the deflection roller can also be provided.
  • the deflecting roller is preferably coupled to a hydraulic pump operating as a brake, wherein in particular the deflecting roller can be connected to the hydraulic pump via a transmission, preferably a toothed belt drive.
  • a double-armed pivoting jack is provided, on one arm of which the spring engages and on the other arm of which carries a support roller for abutment with the removed film and the mirror.
  • the single figure shows a plan view of a satellite of a device for wrapping a stack of goods with an expanded film.
  • a base plate 1 of a satellite can be seen in a device for wrapping a stack of goods with an expanded film.
  • the satellite is suspended from an annular disc, which is rotatable and driven around a vertical axis and is moved up and down in a frame.
  • the satellite makes a circular movement around the stack of goods, not shown, which is to be wrapped with a stretched film.
  • a film roll 2 with a vertical axis 3 is arranged on the base plate 1 of the satellite, one of which is pulled off a film 4 and guided over a deflection roller 5 also mounted on the base plate.
  • the film 4 is pressed against the deflection roller 5 with a pressure roller 6.
  • the deflection roller 5 is braked.
  • the deflection roller 5 carries a toothed ring 8 on an underside, over which a toothed belt 9 runs.
  • the toothed belt 9 is also guided over a further ring gear 10, which is coupled to a hydraulic pump 11 working as a brake.
  • the braking effect on the deflection roller 5 consequently arises in accordance with the respective rotary movements of the deflection roller 5.
  • the braking force is low, so that the satellite reaches the desired orbital speed quickly and without pressure.
  • a double-armed pivot lever 12 is pivotally mounted on the base plate 1 about a vertical axis 13.
  • On one arm of the swivel arm 12 drives a tension spring, the other end of which is fastened to the base plate 1, and the other arm of the swivel arm 12 carries a support roller 15.
  • the arm with the support roller 15 also carries a cooler 16 for a mirror 17.
  • a device 19 with a light barrier is attached to a frame 18.
  • a light beam 20 emanates from there.
  • the swivel arm 12 with the support roller 15 rests on the film side facing away from the device 19 and is held there by the action of the tension spring 14. This is shown in the drawing with solid lines.
  • the light beam 20 is deflected or absorbed by the outer side of the film.
  • the swivel arm 12 is pulled in by the tension spring 14 the position shown by dashed lines is pivoted, at which the light beam 20 strikes the mirror 17.
  • the reflected light beam 20 triggers a pulse by which the drive of the satellite is stopped.
