Definitions

  • the invention relates to a switching device according to the preamble of claim 1.
  • Switching devices for ribbons with two color tracks are known.
  • a magnet pulls the ribbon guide into the red area via a simple lever system in the form of a movable trunk. When the magnet is de-energized, the trunk falls back into the black position of the ribbon due to its own weight or spring force.
  • the object of the invention is to further develop the switching device according to the type of the invention in such a way that it enables switching to four different color tracks of an ink ribbon.
  • an ink ribbon guide 2 is pivotally attached about an axis 4.
  • the ribbon guide 2 serves to guide an ink ribbon 20.
  • a dash-dotted line 3 indicates the center of the print line.
  • the ribbon guide 2 forms, together with a trunk-shaped element 22, which is rigidly attached to it, a lever system 5, which is actuated via two lifting magnets 6 and 7.
  • the lifting magnets 6 and 7 have lifting plungers 8 and 9 which are connected to one another in an articulated manner via a connecting member 13. Between the articulation axes 18 and 19 of the connecting member 13, an articulated connection 14 is provided with a coupling member 10, which has an approximately T-shaped shape in the embodiment shown.
  • the coupling member 10 is a one-armed lever and as such can be pivoted about a pivot axis 11 which, seen from the connection of the lever system 5, lies beyond the lifting plunger 9 of the second lifting magnet 7.
  • Fig. 2 shows a section of an ink ribbon 20 with four different color paths a, b, c and d.
  • the lifting plunger positions of the lifting magnets 6 and 7 shown schematically in FIG. 3 are necessary.
  • the ribbon guide 2 assumes its lowest position, so that the ribbon a is available.
  • the lifting plunger 9 of the second lifting magnet 7 is retracted by switching off the current supply, while the lifting plunger 8 of the first lifting magnet 6 maintains its extended position.
  • both lifting magnets 6, 7 are retracted or not energized.
  • the device can also be used for an ink ribbon 21 with a red ink path r and a black ink path s, in which case, depending on the design of the ink ribbon guide with respect to the line to be labeled, only two adjacent plunger positions a l , b 'and b l , c 'or c', d 'can be used.
  • the principle of ribbon switching addressed by the invention can already be increased to eight possible color paths by adding a further lifting magnet.
