Definitions

  • the invention relates to a cassette for a printing unit for printing objects, such as Letters, parcels and the like, with one between a printhead and an deliverable, retractable counter support insertable, from a in a cassette transportable from a first coil to an adjacent drivable second coil Printing tape formed tape section, which when printing the objects supported at least partially on the counter-support and acted upon by the print head is and before being inserted between the printhead and counter-support the printing unit into an out-of-operation position remote from the print head and the counter-support is relocatable.
  • Thermal printing units are used for printing special characters, in particular stamps on objects, such as letters, parcels and the like, which can vary in a wide range with regard to their geometry, surface properties and other characteristic sizes.
  • the print transfer ribbons used are mostly stored on spools in cassettes.
  • the cassettes are brought into a predefined position with respect to the print head of the printing unit, so that the ribbon runs on the printing surface.
  • the wafer-thin tape or the tape section formed between the reels is often damaged or damaged by the print head.
  • EP-A2-0 604 142 discloses a thermal ribbon cassette for a thermal printer, which has a thermal print head over which a transfer ribbon is guided. In front and after the print head, the transfer ribbon runs around deflecting bars.
  • the cassette has a device for changing the by the printhead and the trailing Band section formed angle, with a guided in a slot Deflection rod, the transfer ribbon is applied to the inside.
  • the transfer belt is prevented from running on the corner wall of the printhead to pass over the second coil.
  • the present invention has set itself the goal of proposing means that overcome these disadvantages. At the same time, the time required to insert a new cassette should be reduced. Furthermore, a franking machine is proposed as the application of the cassette, in which the cassette is easy to replace when changing the tape or the printing unit can be easily retrofitted.
  • a bracket is arranged on a cassette housing so as to be pivotable about an axis parallel to the axis of rotation of the reel, which on the protruding or swiveling end engages when the bracket is actuated on the inside of the tape Has bandwidth on the band section acting deflection rod.
  • the advantage of the cassette according to the invention is seen primarily in the ease of use. Before the cassette is inserted into the printing unit, the section of tape that can be acted upon by the bracket or the deflection rod must be in the insertion position. The deflection bar keeps the tape away from the pressure position. After the cassette has been completely assembled, the movable bar moves the deflecting rod into a rest position, in which the ribbon is not touched by the deflecting rod and lies against the print head in the region of the ribbon section.
  • the tape 4 forms a tape section 6 between the spools 2, 3, which is movable from the printhead 10 by a bracket 8 which has a deflection rod 7 and can be pivoted here about an axis 9 and which could also be designed to be displaceable.
  • the ribbon section 6 extends indirectly between the spools 2, 3 from a deflection roller 11 to a guide roller 12, on which the ribbon 4 is more or less deflected, between which the print head 10 is arranged.
  • the cassette 1 shows the tape 4 in a position lifted from the print head 10, in which it can be inserted and carried out undisturbed parallel to the axes of the spools 2, 3 at a distance from a counter-support 13 designed as a driven conveyor roller.
  • the bracket 8 is locked by a lever 14 in a detent 15.
  • the cassette 1 can be inserted into and removed from an insertion device of the printing unit.
  • the stationary rotatable roller 17 shown is provided, which forms a feed nip with the conveyor roller 13 during the printing process (see also FIG. 2).
  • the cassette 1 is in the final operating position in the printing unit.
  • the tape 4 was moved or moved back to the print head 10 in the area of the tape section 6, the deflecting rod 7 assuming a rest position on the cassette housing 5 in which it moves from the band 4 or band section 6 is spaced.
  • the counter-support 13 and the print head 10 hold the tape 4 or the stretched tape section 6 clamped; the distance between the counter-support 13 and the roller 17 is closed to promote the conveyance.
  • the tape 4 or tape section 6 extends at an approximately right angle around the print edge of the print head. This course of the print ribbon on the print head is known and is therefore not described in detail here.
  • the bracket 8 can be used an actuating handle may be formed, for which the lever 14 is provided, for example is.
  • the bracket 4 could also be designed to be positively controllable, such that the deflecting rod 7 when inserting the cassette 1 into the printing unit or when removing it by an insertion device on the printing unit into one of the printing head 10 lifted position of the belt section 6 is controlled.
  • bracket 8 could be removed from the cassette 1 in the printing unit the rest position of the deflecting rod 7 can be moved back or moved automatically be trained.
  • the cassette 1 could Have a safety element designed as a push button that pushes the Cassette in the insertion device of the printing unit with the deflecting rod set back 7 prevented.
  • the cassette according to the invention is particularly suitable for use in a Franking machine.
