Definitions

  • the invention relates to a device for a mechanical, preferably electromechanical printing unit for setting ink ribbon on different tracks transverse to the running direction on a carrier which can be transported in the line direction in the writing unit, on which a ribbon supply is arranged and the ink ribbon past a printing device through a printing area to one optionally also the ribbon holder containing the ribbon supply is guided.
  • the setting of different traces of ink ribbons in printing units is carried out for two different reasons.
  • it is important to use color ribbons as evenly or completely as possible on the other hand, it may be necessary to switch from one color track to the other in the case of two-color inked color ribbons to switch the color of the print.
  • the switching of parallel color tracks from color ribbons is particularly often to be carried out if more than two colors are used in modern electromechanical printing units, so that several ink ribbons are passed parallel to one another at the printing device and each have to be switched to the printing position.
  • a disadvantage of such swivel devices is that the ribbon, due to its guidance on a relatively long swivel element, moves from one track to another on a circular arc during the adjustment, so that the individual tracks are not guided past the printing point in the same way, but depending on switched on track is caused an oblique position of the ribbon relative to the printing point, which can lead to an uneven font when printing, because the ribbon has the height of a character to be reproduced a variable distance from the printing device on the one hand and from the recording medium to be printed on the other.
  • Disadvantages of this type appear particularly clearly in fast printers which, for. B. work with high-speed wire-dot print heads.
  • a uniform position of the ink ribbon in the printing zone must be ensured, because this high operating frequency of the print head means that the printing process is largely determined by the precise positioning of all sections of an ink ribbon.
  • pivotable guide forks is also only possible in devices in which the ribbon supply and the ribbon holder are coil-shaped and the ribbon is thus unwound from one spool, passed through the printing area and wound onto the other spool.
  • ribbon cassettes which contain the ribbon supply and the ribbon holder and which, for. B. are simultaneously provided with a rigidly molded guide for the ribbon in the printing area fails a switchover of the previously known type.
  • it would be possible to tilt such ink ribbon cassettes this would also require a quite extensive tilting mechanism which could only take up and switch over several cassettes lying one above the other with considerable effort.
  • a special holding device is arranged on the carrier, which does not have to be pivoted or tilted, but is guided displaceably transversely to the running direction of the ink ribbon on the carrier is.
  • the invention thus makes it possible, on the one hand, to use the traces of one or more ribbons uniformly, and on the other hand to switch from one color track to the other in a very simple manner if appropriately colored ribbons are used. So it is possible, for example, to switch to the lower one with only one ribbon after using the upper half of the ribbon, z. B. set different color traces.
  • the drive device which transports the holding device transversely to the running direction of the ink ribbon.
  • a particularly advantageous and easy work Tende construction is characterized in a further embodiment of the inventive concept in that the drive device comprises a cam drive, which moves a drive element connected to the holding device by its rotation in a number of designated ribbon tracks corresponding number of positions transverse to the direction of the ribbon.
  • cam drive for the adjustment of the ribbon tracks offers the advantage that a high accuracy of the track adjustment is achieved with the greatest possible simplicity of the drive mechanism.
  • a cam disk which generates correspondingly different working strokes due to its different distances from the axis of rotation, can have a range of constant distance from the axis of rotation for the working stroke to be achieved in each case, as a result of which a highly precisely controlled drive is not required for its rotation. When the respective range is reached, it is also permissible to continue running a drive motor within certain limits without changing the working stroke.
  • cam disc drive two cams on a common axis of rotation of which actuates a drive member and the walls - re as a counter-support for guided to their pulling device is used, which acts upon the holding device in the direction of the first cam way.
  • This training enables the harmful influence of e.g. B. caused by thermal expansion or other mechanical play tolerances and also ensures a permanent seat of the drive element for the holding device on the first cam, because the holding device is continuously drawn by the traction device guided on the second cam towards the first cam.
  • the two cams are advantageously designed so that the distances between the curve points of the first cam to the common axis of rotation form constant sums with the distances of the diametrically opposite curve points of the second cam to the common axis of rotation.
  • constant tensile or compressive stresses are always generated between the drive element for the holding device and the pulling device guided on the second cam disk, so that a consistently accurate compensation of tolerances is ensured over the entire stroke range of the holding device.
  • the drive element and a traction element guided on the second cam plate are expediently on a straight line which runs in the direction of the movement stroke through the common axis of rotation.
  • the pulling device is connected to the holding device by means of a tension spring, the constant, firm pressure of the drive element on the first cam disc further improved, and regardless of wear and tear on the cam discs, tolerance-free guidance is maintained during the stroke movement.
  • FIG. 1 an electromechanical printing unit is shown in front view and partially broken view, the platen roller 1 (FIG. 2) not being recognizable according to the viewing direction 1-1 indicated in FIG. 2.
  • the printing unit is held between two side boards 35 and 36, which belong to a device frame. Between these side plates 35 and 36, two guide rods 7a and 7b are held, on which a carrier 2 is guided by means of guide rollers 6a and 6b (FIG. 2), that it can be transported by a drive, not shown in FIG. 1, in a manner known per se, on the guide rods 7a and 7b in order to produce a print line running parallel to the guide rods 7a and 7b on a recording medium which is shown on the one shown in FIG Platen roller 1 is arranged.
  • the carrier 2 carries a printhead 3 on a holding device 9 to be described, which printhead is a dot-matrix printhead in the exemplary embodiment shown and can produce characters on a recording medium in a printing area 4c with printing needles not shown.
  • the carrier 2 which can also be referred to as a carriage with regard to its guidance with guide rollers 6a and 6b on the guide rods 7a and 7b, carries the holding device 9 on guide rods 27a and 27b which are screwed to the holding device 9 at 30a and 30b and are guided on the carrier 2 in guide bushes 28a and 28b, so that the holding device 9 with the print head 3 arranged thereon can be raised or lowered in the vertical direction with respect to the illustration in FIG. 1.
  • the holding device 9 is designed as a support plate on which, in addition to the print head 3, two ink ribbon cassettes 4 and 5 are held one above the other.
  • These ribbon cartridges 4 and 5 can be formed, for example, according to US Pat. No. 4,213,715 be. They are held on the holding device 9 in that they are attached to stud bolts 10 which can be provided with locking grooves in a manner known per se in order to hold the ribbon cassettes 4 and 5 in place. To maintain a predetermined distance between the ribbon cassettes 4 and 5, spacers 11 of predetermined thickness are provided.
  • the ink ribbon cassettes 4 and 5 are held on the holding device 9 by means of a spring clip 12.
  • the ink ribbons contained in the ink ribbon cassettes 4 and 5 are guided through guide channels provided on the ink ribbon cassettes 4 and 5 and integrally connected to them after exiting the respective ink ribbon cassette 4 and 5, respectively, then reach a printing area, which is shown in FIG. 1 at 4c , and are then returned to the respective ribbon cassette 4 or 5.
  • Fig. 1 it is indicated that the ribbon in the upper ribbon cassette 4 has two tracks 4a and 4b and the ribbon in the lower ribbon cassette 5 has two tracks 5a and 5b. These tracks can be colored differently, but it is also possible to provide ribbon tracks of the same color.
  • the holding device 9 on the carrier 2 is to be moved upwards until the area 5c of the lower ink ribbon reaches the position where the printing area 4c is shown in FIG. 1 .
  • the two areas 4c and 5c are formed by windows in a pressure point guide 9a connected to the holding device 9, into which the respective ink ribbon is inserted from above when the respective ink ribbon cassette 4 or 5 is placed on it.
  • the respective window releases the ink ribbon guided past it in such a way that the printing needles of the wire print head 3 hit the ink ribbon and its color can be transferred to the recording medium.
  • a drive device 13 is provided under the carrier 2, which is driven by an electric motor 18.
  • the electric motor 18 and the drive device 13 are mounted on a frame which is formed by side plates 14 which are connected to one another via bolts 14a.
  • the one side board 14 is this Frame shown broken, so that a cam 15 behind it can be seen, which can be rotated on an axis 17 mounted in the side plates 14.
  • the drive motor 18 is coupled to the axis of rotation 17 via a gear transmission with gear wheels 19.
  • the cam disc 15 has four sections I, II, III, IV, which have a continuously increasing distance from the axis of rotation 17.
  • a driving roller 21 is guided on the cam plate 15 and is mounted on a lifting plate 20 which is rigidly connected to the holding device 9. If the cam disc 15 rotates counterclockwise in the direction of the arrow shown in FIG. 1, the driving roller 21 will pass from section I of the cam disc 15 into section II, so that this no longer causes the ribbon track 4a but the ribbon track 4b in the printing area 4c is arranged.
  • the driving roller 21 When the cam disc 15 rotates further, the driving roller 21 reaches the sections III and IV, so that the holding device 9 is then raised further via the lifting plate 20 and the ribbon sections 5a and 5b reach the printing area 4c.
  • the holding device 9 with the ink ribbon cassettes 4 and 5 arranged thereon is conveyed to a height which corresponds to the desired positioning of an ink ribbon track 4a, 4b, 5a, 5b in the printing area 4c.
  • a gear transmission 29 with a drive motor is shown below the lower ribbon cassette 5 on a carrier element 9b connected to the holding device 9, through which the ribbons can be transported in a manner not shown during the printing operation.
  • FIG. 2 shows an illustration of the printing unit according to section 2-2 shown in FIG. 1.
  • the assignment of the ribbon track 4a to the print area can be seen particularly clearly here, i. H. it is arranged at a point directly opposite the platen roller 1.
  • a toothed drive belt 8 is shown, which is not shown in FIG. 1 for a better overview and which is used to transport the carrier 2 in the printing line direction in a manner known per se. It can also be seen in which way the two ink ribbon cassettes 4 and 5 are held on the holding device 9 by the spring clip 12, which is anchored to the holding device 9 at 12a.
  • the gearwheel gear with the gearwheels 19 in coupling with the drive motor 18 and the first cam disk 15, on which the driving roller 21 is guided can be seen.
  • a tension rail 23 Arranged parallel to the lifting plate 20 is a tension rail 23, which is connected at its upper end to the holding device 9 via a tension spring 24, which is anchored to it at 24a.
  • the tension spring 24 is anchored to this at 24b.
  • a driver roller 22 At the lower end of the pull rail 23, a driver roller 22 is provided, which is guided on a second cam 16.
  • This second cam 16 sits on the axis of rotation 17 of the first cam 15 and serves to guide the driving roller 22 during the rotation of the first cam 15 so that the tension on the holding device 9 in the downward direction is as constant as possible via the tension rail 23 and the tension spring 24 is exercised so that the driving roller 21 is always sufficiently pressed against the cam 15 and the holding device 9 is always guided firmly and tolerance-free during its lifting movement.
  • the shape of the second cam plate 16 provided for this purpose relative to the first cam plate 15 and the mutual assignment of the driving rollers 21 and 22 will be described below with reference to FIG. 3.
  • FIG. 2 also shows a clock disk 26 arranged on the axis of rotation 17 of the two cam disks 15 and 16, which has slots which are translucent at regular intervals in a manner not shown.
  • This clock disk 26 is assigned to an optical signaling device 25, which contains a light source and a light sensor and can generate signals when passing the translucent slots of the clock disk 26, which signals are fed to a control device 40 for the drive motor 18.
  • control device drives the drive motor 18 Receiving a switchover command for the ribbon tracks 4a, 4b, 5a, 5b, it can compare in a manner known per se the desired position of a ribbon track to be set in each case with the respective actual position determined by counting pulses from the reporting device 25 and the drive motor 18 Switch off when the target position is reached, since the target position then matches the actual position. Controls of this type are known per se and therefore do not need to be explained in more detail here.
  • FIG. 3 the shape of the two cams 15 and 16 and the assignment of the driving rollers 21 and 22 actuated with them is shown in a partial view.
  • the cam 15 has the shape already explained with reference to FIG. 1, so that it enables the setting of four different ribbon tracks.
  • the pull rail 23 is now arranged so that the driving roller 22 held at its lower end on an axis 22a lies on a common straight line with the driving roller 21, this line running through the center of the axis of rotation 17 of the two cams 15 and 16.
  • the pull rail 23 is provided with an elongated hole 23a in the region of the axis of rotation 17 and the lifting plate 20 for the driving roller 22 with a slot 20b in the region of the axis 22a.
  • the circumference of the cam disk 16 is now dimensioned such that the sum of the distances between the driving rollers 21 and 22 from the common axis of rotation 17 of the two cam disks 15 and 16 is constant. In this way, that by the cam 15 the distance between the driver roller 22 is to the common rotational axis 17 to the extent smaller during the lifting of the lifting plate 20, as that distance between the driver roller 21 to common D axis deer 17 increases is ensured. It is thereby achieved that the tension rail 23 pulls the holding device 9 downward under largely uniform loading of the tension spring 24 and the driving roller 21 always lies evenly on the cam disk 15. Any tolerances that can be caused, for example, by stretching or by play due to wear of the cam disks 15 and 16 or other mechanical elements are compensated for, so that a lifting and lowering movement of the holding device 9 which is always free of play can be achieved.
  • the cam plate 15 has a largely constant distance from the axis of rotation 17 in the area of the sections I, II, III and IV, as a result of which a certain inaccuracy of the drive device 13 or after-running of the drive motor 18 can be accepted after switching off.
  • the position of an ink ribbon track 4a, 4b, 5a, 5b once reached is then maintained regardless of such drive tolerances.
