Definitions

  • the invention relates to a device for delayed drive shutdown of document shredders according to the preamble of claim 1.
  • the delayed drive shutdown has the purpose of ensuring that the drive is stopped only when the cutting unit is cleaned, that is, from paper particles cutting dust etc. has run free and, above all, the respective document has been completely destroyed.
  • electronically acting components already assigned to the drive control are known in practice, but their special disadvantage is their relatively high price.
  • Pneumatic devices are also known, the one with an air cylinder and delay valve work.
  • the specific disadvantage lies with this type of construction in the relatively high price and the susceptibility to failure of the many precision mechanical components.
  • the hitherto known electronic as well as pneumatic Delay elements as the main disadvantage of the property peculiar that the duration of the header overrun has to be empirically preset; however, since it is generally known that depending on the type of paper the "self-cleaning time" of the cutting units is very different, especially with very thin Paper takes a very long time, the previously known Systems are always only a little effective Compromise solution.
  • the duration of the Follow-up time for document shredders without any values to be preset are purely dependent on the load and to influence independently, d. i.e., the Only stop the drive when the Cutting rollers are actually completely free, are cleaned.
  • the switch-on takes place of the roller drive motor 4 in known Way automatically when inserting a sheet of paper or the like. into the cutting gap between the rollers in a purely mechanical way via the cams 2a of the with the limit switch 3 interacting rocker switch Second
  • the return element is designed as a compression spring 9 and ends on the axis 8 between the wheel hub 7 and the bearing plate 11 is arranged; is also conceivable any other type and arrangement of a discharge of the cutting unit becoming effective elastic return member.
  • illustrative embodiment is the parent of the present invention technical teaching especially in that at least one of the drive motor 4 and cutting roller pair 1 lying gear stages 5, 6 and / or 13, 14 provided with helical teeth 6a and at least one of the gears 6, 7 or 13, 14 axially movable (stroke x) on its axis (e.g. 8) stored and in the area of the axial stroke x one with the Motor control linked switching element, preferably a limit switch 10, 10a is arranged.
