Definitions

  • the invention relates to a device for transporting record carriers in printers, in particular in matrix printers, in which single sheets or alternately endless webs with and without edge perforation can be processed, a tractor abutment for endless webs and driven and non-driven pressure rollers or pressure roller pairs being assigned to a writing abutment.
  • Such paper transport devices serve the purpose of a full support on the print abutment and thus also a line-precise feed, the feed when inserting and removing must take into account the detection of the end of a paper web or a single sheet or a copy set (form set).
  • Paper transport devices which can be used for continuous webs and single sheets at the same time are known (EP-A2-0 099 120).
  • This known paper transport device consists of a mounting assembly that transports single sheets in a lying position with the tractors for continuous webs perforated at the edge and in a vertical position of the mounting assembly.
  • an attachable transport device on the attachment module itself. Modules that can be placed in this way cannot be manufactured and assembled with sufficient accuracy and require impermissibly large tolerance values.
  • additional components are required, so that this design causes great effort and thus high costs.
  • the high assembly costs are also disadvantageous.
  • the invention is therefore based on the object of a device for transporting different recording media (perforated continuous paper webs, non-perforated continuous webs, single sheets, Copy sets, form sets) with a minimum of parts, whereby the assembly effort must also be taken into account.
  • the object is achieved according to the invention in a device of the type described in the introduction in that one or more pressure roller groups, each consisting of a plurality of roller pairs, are provided, that each pressure roller group is arranged on its own bearing frame, and that the bearing frame is moved from a rest position into a position by means of a common adjusting element Operating position or vice versa are adjustable parallel to the platen.
  • a device is the simplest solution to feed, advance, i.e., punch perforated endless webs, non-perforated endless webs, single sheets, copy sets and form sets. to be able to process overall.
  • the effort provided for this only includes a pressure roller group integrated into the office machine or the printer, which can be switched on and off.
  • a pin-shaped cylindrical abutment (platen roller) can advantageously be assigned this pinch roller group on the circumference in such a way that the transfer of the single sheets or paper webs can take place with a full support on the abutment. In this case, the guiding and pushing or tensile forces are separated such that the pressure roller group has only non-driven roller pairs.
  • a particularly cost-effective assembly results from the fact that the bearing frames can be inserted and latched or unlocked and removed when the platen roller is removed from the printer frame through openings in the printer frame.
  • the system can therefore be used particularly advantageously in printer designs in which the platen roller with its bearings can be easily expanded.
  • the common adjusting member consists of a rotatable D-axis mounted in the side plates of the printer frame, each of which is provided by recesses in the bearing frame runs.
  • a non-positive and / or positive assignment of the D-axis to these recesses does not require large tolerances and is therefore particularly inexpensive to manufacture and assemble.
  • an adjusting lever connected to the D-axis is provided on the outside of the side plate, the pin-shaped end of which is guided in an obliquely upwardly extending recess.
  • the obliquely upward recess allows the D-axis to be raised and lowered when the adjustment lever is pivoted.
  • Another improvement of the invention is that the individual pairs of rollers are mounted in the bearing frame radially compliant above by means of a flat spring through openings in the upper side of the bearing frame.
  • the printer frame 1 consists of the side boards 2 and 3 and a connecting piece 4, which also forms one side of a paper guide channel.
  • the connecting piece 4 is curved because a circular cylindrical platen 6 is provided as the abutment 5.
  • the platen roller 6 is hung on the journal 7 by means of axle holders 8 in associated bearing cutouts 9. The assembly movement during hanging is shown by dash-dotted lines 10.
  • driven pressure roller pairs are used for endless tracks instead of the driven transport rollers 12 shown.
  • the drive takes place via a gear wheel 13 on the axis of rotation of the platen roller 6, which is itself driven by an electric motor (not shown).
  • the gear 13 rotates a further gear 14 on the shaft 15, which is rotatably supported in a cover 16 and carries a plurality of transport rollers 12, which are opposed in the cover 16, non-driven, radially spring-mounted counter-rollers 17.
  • the tractor pair 11 is adjustable on an axis 18 and a drivable shaft 19 to the width of the endless track 20.
  • a print head carriage 22 with a print head 23 can be moved in parallel in front of the writing abutment 5.
  • the drive for the pair of tractors 11 is switched on, so that the endless web 20 passes the arched connecting piece 4 and passes around the platen roller 6 in front of the print head 23, is labeled there and then by the transport rollers 12 and the counter rollers 17 are conveyed from the office machine.
  • pressure roller groups 24 and 25 which each have several pairs of rollers 26.
  • Each of the pressure roller groups 24 and 25 is mounted on a separate bearing frame 27 (made of plastic) which is adapted to the curvature of the connecting piece 4. All bearing frames 27 are adjusted from a rest position into an operating position or vice versa parallel to the platen roller 6 by a common adjusting member 28. 2, the bearing frames 27 are in their rest position and therefore do not exert any frictional forces on the endless track 20.
  • the adjusting member 28 is now actuated, whereby a single sheet 29 is pressed through the single sheet shaft 30 via the frictional forces of the roller pairs 26 onto the platen roller 6.
  • the bearing frame 27, its actuating means and its assembly are described in more detail below. 1 shows, the bearing frames 27 are inserted into openings 31 when the platen roller 6 is removed from the printer frame 1. Of course, during the initial assembly, the mounting of the bearing frame 27 can take place before the platen roller 6 is installed.
  • the common adjusting member 28 is formed by a D-axis 28a, which run through recesses 32.
  • the bearing frame 27 forms these recesses 32 through left and right of the D-axis 28a on web walls 33 vertically extending guide rails 34 and 35.
  • the D-axis 28a is connected to an adjusting lever 36.
  • the adjusting lever 36 has a peg-shaped end 36a, which is guided in an obliquely upward recess 37.
  • the D axis 28a itself is guided in elongated holes 38 in the side plates 2 and 3, in which the D cross section slides to different heights, ie to a lower layer according to FIG. 2 and to an upper layer according to FIG. 3.
  • the individual pairs of rollers 26 are rotatably supported by means of a flat spring 39 projecting through openings 40 in such a way that they protrude radially resiliently on the upper bearing frame side 27a and can be installed or removed together with the bearing frame 27 as a unit (FIG. 1).
  • the web walls 33 in this case carry latching arms 41 (FIG. 1) which can be resiliently pivoted transversely to the guide direction of the print head carriage 22.
  • roller pairs 26 After installation of the bearing frame 27, the roller pairs 26 are pressed against the platen roller 6 with uniform force distribution on all rollers. Unevenness and different thicknesses in the paper as well as concentricity tolerances of the platen roller 6 and the roller pairs 26 are compensated for by the resilient inherent movement of the roller pairs 26. The roller axes remain parallel to the platen roller 6.
