Definitions

  • the invention relates to a device for cleaning curved surfaces according to the cloth principle with an unused cleaning cloth carrying a cleaning cloth roll, a used one Dirt-absorbing cloth roll, the cleaning cloth in operative connection with the pressing element to be cleaned and means for removing the cleaning cloth from the cleaning cloth roll and rolling onto the dirty cloth roll.
  • the pressure element is a functional unit and to provide it with an elastic bead facing the surface to be cleaned.
  • This pressure element is displaceably arranged by means of pneumatic actuating means and can thus be brought into or out of engagement with the surface to be cleaned in each case.
  • These cleaning devices furthermore have means for pulling off the cleaning cloth provided on the cleaning cloth roll and means for rolling up the soiled cleaning cloth on the dirty cloth roll.
  • means are provided in these devices which ensure that constant cleaning cloth sections are pulled off the cleaning cloth roll.
  • the diameter of the dirty tissue roll is scanned and the angle of rotation of the driven dirty tissue roll is limited by a mechanical control depending on the diameter.
  • the object of the invention is to provide a device for cleaning curved surfaces To create a cloth principle that with simple means and a small footprint Way to be realized.
  • the solution according to the invention ensures with simple means that independent of the diameter of the clean cloth roll or the dirty cloth roll always the same Cloth sections are pulled off and fed according to the dirty cloth roll. Moreover is a by pulling off the cleaning cloth using the pressure element space-saving and cost-effective implementation possible.
  • a cylinder 1 to be cleaned is shown with a device for cleaning 2 designed as a functional unit in a sectional side view.
  • the device for cleaning 2 can have, for example, a frame 3 in which all components are arranged, so that the device for cleaning 2 can be removed from the machine in its entirety.
  • the device for cleaning 2 has a cleaning cloth roll 4 which is provided with an unused cleaning cloth 5.
  • the cleaning cloth roll 4 is rotatably connected to a spindle 6, which in turn is rotatably connected to a toothed belt pulley 7.
  • the cleaning cloth 5 is guided by the cleaning cloth roll 4 past a pressure element 8 to the dirty cloth roll 9.
  • the dirty cloth roll 9 is connected in a rotationally fixed manner to a spindle 10, which in turn is connected to a toothed belt pulley 11 via a slip clutch 22.
  • the spindle 10 is also assigned a ratchet 12, which permits rotation of the spindle 10 and thus of the dirty tissue roller 9 only in the direction of rotation 13.
  • the toothed belt pulley 7 and the toothed belt pulley 11 are connected by a toothed belt 14.
  • the toothed belt 14 is guided with the aid of guide rollers 15, which correspond to the toothed belt pulley 7 or with the toothed belt pulley 11, and by means of a tensioning roller 16, which is supported by an energy accumulator 17 which is supported against the frame 3 and is designed as a compression spring 18 in the exemplary embodiment , curious; excited.
  • the pressing element 8 consists of a base body 19 arranged in the frame 3, in which extends a pressure body 20 which can be pressurized and relieved of pressure by means not shown. When the pressure is released, the pressure body 20 assumes the position shown in the full line representation, while when the pressure is applied, the pressure body 20 changes to the position shown in broken lines.
  • the pressure body 20 is selected in such a way that the pressure surface 21 travels a long way under a pressure load.
  • the pressing element 8 in such a way that in the area facing the cylinder 1 to be cleaned it has an elastic zone extending parallel to the cylinder 1 and the pressing element by adjusting elements from a detent position distant from the cylinder 1 to a working position, in the cleaning cloth 5 is in operative connection with the cylinder 1, can be spent.
  • the mode of operation of the device for cleaning 2 is as follows: in a rest position, the pressure body 20 is relieved of pressure and the cleaning cloth 5, the toothed belt 14, the tensioning roller 16 and the pressure body 20 are shown in full lines. If the cylinder 1 is to be cleaned, the pressure body 20 is subjected to pressure and thus reaches the position shown in broken lines, the cleaning cloth 5 being pulled off the cleaning cloth roll 4. The locking mechanism 12 prevents the cleaning cloth 5 which is wound on the roll of dirty cloth 9 from being pulled off. When the cleaning cloth 5 is pulled off the cleaning cloth roll 4, the toothed belt pulley 7 is rotated at the same time.
  • the sag of the toothed belt 14 in the empty strand is increased (dashed line) while the toothed belt 14 in the load strand is tightened so that the tensioning roller 16 moves from the full line line to the dashed line Representation spent and the compression spring 18 is tensioned. If the pressure body 20 is relieved of pressure, for example when the cleaning process is finished or a clean cleaning cloth section is required, the tensioning roller 16 moves back into the starting position due to the action of the compression spring 18, whereby the dirty tissue roller 9 rotates in the direction of rotation 13 and thus the cleaning cloth 5 onto the Dirty cloth roll 9 is wound up.
  • the slip clutch 22 is set so that it only responds when the cleaning cloth 5 to be wound is taut.
  • the speed ratio from the toothed belt pulley 7 driven by the cleaning cloth roll 4 to the toothed belt pulley 11 driving the dirty cloth roll 9 is selected such that, regardless of the respective ratio, the diameter of the cleaning cloth roll 4 to the dirty cloth roll 9 can be wound up more and more or exactly as much cleaning cloth 5, as is pulled off the cleaning cloth roll 4 by the pressure element 8.
  • connection between the cleaning cloth roll 4 and Dirty cloth roll 9 shown using a toothed belt gear. But it is also possible to provide any traction mechanism 23.
