Definitions

  • the invention relates to a device for transport monitoring according to the preamble of claim 1.
  • the object of the invention is to provide a device for monitoring the transport of a band-shaped carrier stored in a cassette, e.g. of an ink ribbon, which is simple in design and which also allows a ribbon end preview without additional effort.
  • the transport of an ink ribbon can be monitored particularly easily by the interaction of the supply roll with a deflection roller provided with an impeller, which in turn is mechanically or optically scanned.
  • the supply spool is in frictional connection with the deflection roller via the ink ribbon.
  • the supply reel itself is slidably mounted in slots in the cassette housing. With a certain remaining tape length, the core of the supply reel comes into the rotation range of the impeller, whereby it is stopped in a fluid manner. The absence of signals from the scanning device means that the tape standstill is recognized. However, the remaining length can still be unwound from the supply reel, since only the impeller and not the band itself is stopped, the band sliding over the deflection roller connected to the impeller.
  • the movement of the impeller can be sensed mechanically on the one hand in a simple manner, on the other hand by means of a reflection scanner designed as an optoelectronic sensing device.
  • An ink ribbon cassette 1 contains a supply reel with a supply reel 3 and a take-up spool 4 located on a winding core 2.
  • the supply spool is slidably guided in slots 5 of the cassette housing and is in frictional connection with a deflection roller 6.
  • Via a take-up spool, not shown here 4 driving electromotive device the ribbon is unwound from the supply reel 3 in printing operation, deflected via the guide roller 6 and spooled onto the take-up spool 4.
  • a device for transport monitoring which consists of an impeller 7 connected to the deflection roller 6, each with three actuating elements and a scanning device which scans the movement of these actuating elements and converts them into an electrical signal.
  • This scanning device essentially consists of a conical feeler mandrel 8 which is fastened on a spring plate 9 arranged in the bottom of the cassette holder.
  • the spring plate 9 has a tab 10 at its end, which engages in the signal path of a light barrier 11.
  • the deflection roller 6 with the impeller 7 is moved over the ink ribbon 12.
  • the wings (actuating elements) of the impeller 7 slide over the truncated cone of the feeler mandrel 8 and press the feeler mandrel and thus the tab 10 into the signal path of the light barrier 11 (shown in broken lines).
  • the signals emanating from the light barrier 11 are evaluated via a circuit arrangement, not shown here. Becomes if the movement of the ink ribbon 12 is interrupted by a torn ribbon or by jamming, the light barrier 11 is not actuated further and the subsequent evaluation circuit reports this fault.
  • the movement of the impeller 7 can also be sensed directly via a generally known reflection scanner, not shown here.
