Definitions

  • the invention relates to a drive device for the knife rollers of a document shredder, consisting of an electric motor with a reduction gear and a so-called overrunning clutch in the form of a driving pin at one end of one of the shafts of the knife rollers, in the plane of rotation of which on the same shaft end seated drive wheel a stop with two stop surfaces is provided.
  • such a document shredder drive equipped with an overrunning clutch is known specifically from the generic DE-B-16 11 752 and is used primarily for malfunctions due to blockages or Jamming of clippings, for the free running of the knife rollers in the reverse gear and the restart in the forward gear under load, always to have sufficient torque available.
  • the known reduction gear made up of toothed belts and corresponding pulleys, has a pin located at the end of one of the knife roller shafts, which cooperates with a stop with two stop faces attached in its plane of rotation to the associated pulley.
  • Such an overrunning clutch may work quite satisfactorily with reduction gears equipped with toothed belts, but not with those that essentially consist of gear wheels, especially when it comes to inexpensive plastic wheels that are used more and more in mass production today.
  • the object of the present invention is therefore also to construct means and measures to be provided which definitely exclude the aforementioned risk of tipping.
  • the knife rollers 11 are, for example, via ball bearings 17 in the Mounted side parts 1, which together with the bottom 2 and the cross struts 4 form the frame of the document shredder drive.
  • the electric drive motor 5 in the form of a reversing motor and a bearing plate 3 for holding a toothed wheel 7, which meshes with the drive pinion 6 of the motor 5, are seated on the side part 1 shown.
  • the actual overrunning clutch now consists in the fact that the two flat sides 9a and 9b of the intermediate wheel 9 have recesses 14 in the hub region and these stop surfaces 15 and 16 delimiting them on both sides, and the drive shaft extension 12a of the associated cutter roller shaft 12 has driving pins 13 which are associated with the recesses 14 and stop surfaces 15 and 16 correspond.
