Definitions

  • the invention relates to an ink ribbon cassette for writing and / or printing machines, consisting of a housing with a housing base and two housing side arms, an ink ribbon, an unwinder spool, a winding spool and drive means controllable by the machine for further transport of the ink ribbon, the ink ribbon between the two housing side arms runs freely outside the housing, and the housing side arms have guide webs in a plane running parallel to the band plane of the free band section with guide edges pointing away from one another, on which the ink ribbon is guided vertically by means of guide pieces for selecting one of several writing tracks in the band plane of the free band section is andlNicolsachse to B movably guided in such a way that a compensation of different tensions of the band edges is given in the various positions of the free ribbon section.
  • the ribbon is guided freely past the type attachment point over a section between two side arms in front of the roller of the machine.
  • the belt By guiding the belt in its transverse direction, i.e. by moving the tape in parallel, one of several writing tracks on the tape can be selected.
  • the tension of the tape is not constant due to the transverse movement of the freely guided tape area, but changes depending on the selected track in such a way that the two tape edges have different tensions, particularly in the positions of the bottom and top writing tracks. This can lead to a deterioration in the font quality or, in the worst case, even to the tape sticking to the types, especially when using machines with type wheels, which can result in damage to the tape or type wheel.
  • a ribbon cassette is already known in which this disadvantage is to be avoided in that the housing side arms have guide webs for the guide pieces which are directed outwards, ie away from one another.
  • the guide pieces are provided with U-shaped slots which are placed on the guide webs. It is provided that the guide webs have a convexly profiled edge, so that the guide pieces move on a circular path.
  • the distances between the edge zones of the tape guides are not constant, but are variable as a function of the selected writing track.
  • a very precise calculation of the Circular arc, ie the convex curvature of the guide web edges is required, since this type of guide is a forced guide.
  • the band edges With an incorrectly selected curvature, it is still possible for the band edges to have different tensions. Furthermore, due to the guidance of the guide pieces along the outwardly convexly curved guide edges, the distance between the guide pieces is not constant, ie their distance is greater in the position of the middle writing track than in the positions of the upper and lower writing tracks. Since the ink ribbon is moved from the lower starting position to the position of the chosen writing track each time the machine stops, the ink ribbon is pulled off the tape roll by this difference by increasing the distance between the guide pieces when moving into the middle and lower writing track than it corresponds to the transport step of the drive wheel of the machine. However, this results in a lower yield of the ribbon.
  • the invention is therefore based on the object to improve the ribbon cassette described in such a way that a completely uniform and optimal ribbon tension is achieved in all positions of the ribbon with optimal ribbon utilization with a ribbon guide that is simple to manufacture.
  • this is achieved in that the guide edges of the guide webs are arranged over their entire length perpendicular to the longitudinal axis of the tape, and in that the guide pieces are mounted on the guide edges in such a way that they can be tilted about axes perpendicular to the plane of the free tape section and intersecting with the guide edges are. Consequently, there is no positive guidance of the guide pieces as in the known ribbon cassette, but it is essential to the invention that the tape itself regulates the necessary compensation by enabling the guide pieces to be tilted due to its different tape tensions on its edges. As a result, the tension is equal across the entire bandwidth in all positions of the belt, i.e. always optimal in the position of each selected writing track.
  • the guide edges advantageously run in a straight line and parallel to one another, so that the distance between the guide pieces from one another is constant over their path along the guide edges.
  • the tape withdrawal from the supply roll is constant in all tape positions, i.e. regardless of the selected writing track, which results in optimal tape yield.
  • the cassette housing consists of a housing base 3 in which the reels are housed with the wound tape 2, and from two housing side arms 4, which extend from the housing base 3 to the front, ie in the state of the cassette inserted into the machine in the direction of the stop roller.
  • the ink ribbon 2 runs freely between the housing side arms 4 outside the housing between the stop roller and the writing types of the machine. In this section, the ink ribbon 2 is movably guided to select one of several writing tracks perpendicular to the longitudinal axis 5 of the tape (FIG. 6) and in the plane of the free tape section, ie perpendicular to the plane of the drawing in FIG.
  • the housing side arms 4 have guide webs 6 in a plane running parallel to the band plane of the free band section with outwards, i.e. leading edges 7 pointing away from one another.
  • Guide pieces 9 are slidably mounted on these guide edges 7 and have two contact edges 11 for guiding the ink ribbon.
  • the band 2 is guided over the contact edges 11 in such a way that it is simultaneously deflected from the direction of the side arms 4 in the direction of the free band section.
  • the guide pieces 9 have extensions 12 in the side regions of the support edges 11, which grip the ribbon 2 laterally and thus prevent the ribbon 2 from slipping off the support edges 11.
  • the guide pieces 9 by means of rod-shaped wire springs 13 which extend longitudinally through the Housing side arms 4 extend, held in a certain position, preferably in the position in which the uppermost writing track of the ink ribbon 2 runs in front of the type attachment point of the machine.
  • the pretensioning of the springs 13 required for this is achieved by supports 14 which are formed in the lower housing part 1. Against the bias of the springs 13, the movement of the tape 2 is carried out by a control of the machine in order to select further writing tracks.
  • the ribbon 2 can be moved in the free ribbon section between the housing side arms 4 in the direction of the ribbon plane and perpendicular to the ribbon longitudinal axis 5 - see FIG. 6 - but the spools in the housing base 3 do not change their position, the tensions of the ribbon edges 2a and 2b not constant, so that in the band position shown in FIG. 6 the edge 2a would have a higher tension than the edge 2b.
  • the guide edges 7 of the guide webs 6 are arranged perpendicular to the longitudinal axis 5 of the belt over their entire length, that is to say run straight.
  • the guide pieces 9 are advantageously mounted on the guide edges 7 such that they can be tilted about axes 15 (FIG. 1) arranged perpendicular to the plane of the free band section and intersecting with the guide edges 7, which should indicate the double arrows 16 shown in FIG. 3 .
  • the guide pieces 9 have 7 guide grooves 17 for resting on the guide edges, in each of which a the tiltability of the guide pieces 9 generating cams 19 is arranged centrally.
  • each housing side arm 4 advantageously has a further guide web 21, which is arranged parallel to the first guide web 6 in a plane between the free band section and the housing base 3.
  • These second guide webs 21 have straight guide edges 22 which are arranged parallel to the guide edges 7 of the first guide webs 6.
  • the guide pieces 9 advantageously rest on the second guide edges 22 with additional cams 23. This advantageous embodiment prevents the guide pieces 9 from tilting in a direction other than the permitted direction described, and thus ensures reliable guidance of the ink ribbon 2.
  • FIG. 2 shows the tilting position of the guide pieces 9 in the lower position of the tape for the selection of the upper writing trace, in FIG. 3 the middle position and in FIG. 6 the selection position of the lower writing trace. From this it can be seen that the ink ribbon 2 itself can adjust the tilting position of the guide pieces 9 due to different tensions of its edges, so that the optimum ribbon tension constancy always results over the entire bandwidth.
  • the present invention compensates for different tensioning of the band edges while at the same time optimally utilizing the band.
