Definitions

  • the invention relates to a matrix printer, in particular a matrix line printer, with a carrier for the printing elements which can be made to move back and forth, the drive means for the printing elements having electromagnets with cable connections, which consist of flexible strips and are connected via a switching logic to a character generator.
  • Matrix printers of this type are used as data printers in data processing units with high data output or are used in word processing systems as typing printers for texts of correspondence quality.
  • Such a printer is known from DE-AS 22 24 116 or US Pat. No. 3,999,644.
  • a carriage, carriage or the like. equipped with a large number of electromagnets which move a pressure needle in the direction of the pressure roller and have the required cable connections at their rear ends.
  • 33 electromagnets 66 cable connections are required.
  • a disadvantage of such cable connections is the movement of the carrier with the electromagnet, so that the cable connections have to be moved as well.
  • the fastening of the electromagnets on the carrier requires special devices in order to ensure equal distances between the printing needles and a precise vertical alignment with the printing roller or with the recording medium resting on the printing roller.
  • the known solution considers a special holder necessary, which is described in DE-PS 24 24 629. Thereafter, a number of mounts are provided on the bar-shaped support in the longitudinal direction, on each of which a unit-forming electromagnet with its recording pen and its guide is arranged, and each mount has a partially cylindrical seat for receiving the electromagnet and an adjoining back, in which a bearing for guiding the recording pen is arranged.
  • This design does the beam-shaped support heavy and complex and not only makes it more expensive to manufacture, but also has a significant impact on other components of the printer. The result of this is, for example, an electric drive motor which is more powerful in its performance data and more complex guide means for the beam-shaped carrier.
  • the invention has for its object to propose a low-mass carrier for the electromagnets, which is easy and economical to manufacture and which meets all concerns of the pendulum movements of the print head of a matrix printer.
  • the reciprocating support for the printing elements consists of an approximately angular profile bar and that the electromagnets are fastened in the upright profile bar wall opposite the recording medium or the platen, the fastening means from the side of the record carrier or the platen roller are embedded in the profile bar wall and are accessible.
  • the angular profile bar combines the known beam-shaped support and the known holder for the electromagnets in a single functional part and therefore saves considerable moving mass.
  • the angular profile bar can also be selected from commercially available materials and only requires fine machining.
  • the position of the electromagnets can be determined with a high degree of accuracy within narrow tolerance limits by uniform machining of the longitudinal edges and the holes for the electromagnets according to distance and direction.
  • the carrier according to the invention is therefore easy, precise and economical to manufacture.
  • the guidance of the carrier for the oscillating movements can now also be made simple, safe and permanent by providing guide projections on the carrier parallel to the row of the pressure elements in the rest position or in the pressure position, which protrusions rest on rollers mounted on the printer chassis in a stationary manner.
  • the accuracy of the guidance is improved during assembly and any maintenance work that may become necessary on the printer in that the rollers mounted on the printer chassis are individually adjustable.
  • the pendulum movements are transferred to the connecting cables for the electromagnets that are moved. These pendulum movements can be absorbed without endangering the connecting cables in such a way that each of the electromagnets at the cable connections for the electromagnetic coil are connected to flat conductors insulated in a carrier material, which are guided in an arc from the moving carrier to a fixed plug contact.
  • the arcs of the individual conductors unpredictably allow movement across the flat conductor cross section due to the arc in continuous operation.
  • the desired arch shape is easily derived from the low bending resistance of the conductors with a flat cross-section.
  • the like. can be simplified in that the flat, insulated conductors have a small thickness and are individually guided to a common holder and that in the course behind a further holder the flat, insulated conductors are brought together to form a ribbon cable and in the further course individual groups of conductors are formed, which have a plug .
  • the cable connections in the immediate area of the electromagnets can also be laid economically by fastening the individual flat, insulated conductors in the immediate vicinity of the electromagnetic coil by means of a holding strip.
  • a holding strip acts here as a strain relief compared to the soldering points of the connections for the electromagnetic coil.
  • the fastening of the holding strip itself takes place in that the holding strip consists of an adhesive strip.
  • Handling, laying, contact with printer parts and the like. can also be taken into account in that the ribbon cable is provided on both sides with the flexible holders at the transitions of the arc from one conductor direction to another conductor direction.
  • ribbon cable for the print head (carrier with electromagnets and pressure elements) of the printer can also be applied in such a way that for additional electrical devices, such as e.g. Sensors, further flat conductors are provided on the ribbon cable.
  • the matrix printer shown in FIGS. 1 to 3 is designed as a matrix line printer.
  • the pendulum drive itself is only indicated in Fig. 1.
  • the pendulum travel la of the carrier 1 is e.g. approx. 6.5 mm on both sides, so that at least one full-width character in matrix notation is covered.
  • the electromagnets 4 are constructed in the manner of a moving core magnet, so that the pressure elements 2 are always held in a rearward position or are fired into a front printing position after actuation of the electromagnet 4.
  • pressure hammers with pressure peaks can also be used as pressure elements 2, such pressure hammers being able to be designed as resilient strips according to the principle of stored energy by means of a permanent magnet and for firing the pressure hammer by means of an electromagnet canceling the magnetic field of the permanent magnet.
  • the electromagnets 4 are connected with the cable connections 3 to a switching logic (control) (not shown) and to a character generator.
  • the matrix printer is equipped with appropriate interfaces for connection to the desired data processing system.
  • the oscillating carrier 1 is made of a light material, such as an aluminum alloy, and forms a profile bar 5 in its basic shape.
  • the carrier 1 can of course also be made as a casting from a light alloy or plastic.
  • the carrier 1 lies opposite the platen roller 6 (as a printing abutment) or the recording medium 7 resting on the platen roller 6 and moving stepwise or continuously, or the ink ribbon 7a (Figs. 1 and 2).
  • the profile bar 5 forms a rear interior space 8 which is open at the top and rear and is delimited by side walls 8a and 8b.
  • An approximately upright profile bar wall 9 (FIG. 3) is provided for the electromagnets 4 and a horizontal plate 10 is provided for the horizontal guide base.
  • the profile bar wall 9 has a rib 11 running in the longitudinal direction in order to arrange the bores 12 for the spacing and alignment of the electromagnets 4 or their pressure needles.
  • the electromagnets 4 have a guide shaft 13 which is threaded.
  • the profile bar wall 9 is inclined slightly upward to allow a clear view of the writing gap.
  • the guide projections 15a, 15b, 15c consist of hardened profile pieces 15d in order to ensure guidance that is as free of play and wear-free as possible in smooth or profiled rollers 17.
  • the rollers 17 can be readjusted individually during assembly or after unavoidable wear.
  • a bearing with an eccentricity 17a serves this purpose.
  • each electromagnet 4 has flat, very thin conductors 18 and 19 in cross section, which are first soldered to the contacts of the respective electromagnetic coil and up to the top of the horizontal plate 10 or to the profile bar wall 9 and are fastened there by means of a holding strip 20 (FIG. 3). From this fastening, the conductors 18 and 19 arranged in parallel next to one another each run in an arc 21 to a contact sleeve 18a of the electronic circuit.
  • the flat conductors 18 and 19 encased in a transparent, insulating carrier material each have a minimum thickness 22. They are guided in pairs 23 to a holder 24 (FIGS. 1 and 4), then run again individually or in groups to a further holder 25 on a cable holder 16a and then form a single ribbon cable 26 which has individual groups 27 of conductors , each ending in a connector 28. These plugs 28 are inserted into the associated contact sleeves 18a of the fixed electronic circuit.
  • the conductor guide described is able (Fig. 2) to the left and right the described pendulum movements of e.g. 6.5 mm without causing damage in continuous operation.
  • the individual flat, insulated conductors 18, 19 are fastened above (or below) the electromagnetic coils 4 by means of the holding strip 20, which consists of a simple insulating adhesive strip 30.
  • the ribbon cable 26 is provided on both sides (FIG. 5) with the brackets 24 at the transitions 29 of the arc 21 from one conductor direction to another conductor direction.
  • 4 and 5 is particularly suitable for additional electrical devices 31, such as for sensors and the like add more flat conductors 32, 33, 34.
  • ground connection 35 is guided to the printer chassis 16 and the conductors 32 are laid to a special connector 36.
  • a conductor guide is a single piece, the conductors of which are insulated on all sides. Only the conductor ends on the conductors 18 and 19 and the contact pins 37 are exposed.
