Definitions

  • the invention relates to a device for paper transport in printers, in particular in matrix printers, for the optional feeding of single sheets or continuous webs, with at least one feed channel for single sheets formed from pairs of friction rollers and a freely accessible push tractor for continuous webs, and with a printing station and one of these Subsequent friction drive in the paper transport direction for both single sheets and endless webs.
  • Such a device is used when printing on different types of paper in a printer and the other type of paper must be kept in a waiting position.
  • a similar device has become known from EP 0 166 132.
  • the upstream arrangement of a pair of friction rollers in the paper transport direction in front of the printing station which works both for single sheets and for continuous webs like the friction roller pair mentioned in the introduction, the latter, however, being arranged behind the printing station in the paper transport direction.
  • the known solution provides a single feed channel for single sheets formed by means of curved guides and a feed channel for endless webs.
  • it is also mandatory to insert single sheets only on the operating side of the printer and endless webs on the back.
  • the known solution also does not allow a tractor of the usual type Flap type to use because there is only space inside the printer for a so-called spiked wheel.
  • the object of the present invention is to perform a functionally complete separation of the otherwise shared feed channels for single sheets and endless webs, with the exception of the pair of friction rollers downstream of the printing station in the paper transport direction, in order to create clear conditions in terms of friction technology.
  • a deflection roller arranged in the paper transport direction in front of the printing station and extending in length over the width of the paper has a swiveling first group of friction rollers for a first feed channel and a second group of friction rollers offset on the circumference, which can be raised and lowered are assigned, and that when the first group of friction rollers is pivoted down and when the second group of friction rollers is lowered, a feed channel for endless webs is formed together with the deflecting roller, which can be advanced by means of the push tractor and can be conveyed out by means of the friction drive downstream of the printing station.
  • This solution means a functional separation of the feed channels for single sheets and continuous webs insofar as single sheets can be pushed from at least one direction (e.g. from the underside of the printer) or from the top side between a deflecting roller and a group of friction rollers in each case, and endless webs with pivoted and lowered groups of friction rollers, which are spaced apart from the deflection roller, are pushed into the printing station solely by the push tractor.
  • the clear separation of the feed channel functions for single sheets and continuous webs, ie the Assignment of separate functional elements for the formation of respective feed channels for single sheets or for continuous webs serves the improved, trouble-free paper insertion with a paper type waiting.
  • both a feed channel from below and another from above can be formed.
  • the position of the feed channels can advantageously be determined constructively by the fact that the deflecting roller has a larger diameter than the friction rollers of the first group and the second group.
  • the pivoting of the first group of friction rollers can now be effected in that the first group of friction rollers is provided by means of hubs and support springs attached to them, and that the ends of the support springs rest in the area of the printer base plate against the cam projections of a first switching axis.
  • the lowering of the second group of friction rollers can be achieved in that the second group of friction rollers is supported on at least one leaf spring by means of a shaft or a plurality of shaft sections, the first leaf spring ends on a fixed support bearing and the second leaf spring ends on Cam cams of a second switching axis rest.
  • Switching from one mode of operation to the other can be effected in that in the area of the first and second groups of friction rollers on a printer base plate each parallel to the friction roller axes running, provided with cam projections switching axles are provided that eccentric pins are arranged in pairs at the ends of the switching axles, which engage in at least one common push rod, that on a tractor shaft driving the tractors, a gear is resiliently axially mounted, which in the engaged state with the Pinion of a drive motor meshes that a coupling axis is provided running perpendicular to the tractor shaft, the shaft shaft of which carries cams bearing against the front face of the tractor gearwheel and that a toothed pinion is attached to the end of the coupling axis and engages in a spur toothing which is provided on the push rod.
  • An actuation option for setting the desired operating mode results from the fact that the coupling axis has a hand rotary knob at its upper, free end.
  • An advantageous alternative embodiment consists of the fact that a deflection roller arranged in the paper transport direction in front of the printing station and extending in length across the width of the paper has a pressure-changing first group of friction rollers for a first feed channel and a second group of friction rollers offset on the circumference can be raised and lowered, are assigned and that when the first group of friction rollers is pressed on with a reduced pressure force and when the second group of friction rollers is lowered, an intake channel for endless webs is formed together with the deflecting roller, which can be displaced by means of the push tractor and can be conveyed out by means of the friction drive downstream of the pressure station are.
  • the support springs or the support spring ends with a base plate are assigned to the first group of friction rollers, that in each case a spring pin is provided on the base plate and that the spring pin is supported in each case by a compression spring against the printer base plate.
  • the device for paper transport in printers allows the optional feeding of single sheets 1 either from below or from above and the feeding of continuous webs 2 from the rear 3 of the printer.
  • feed channels 4 and 5 are formed for the single sheets 1 and a feed channel 6 for the endless webs 2.
  • the feed channels 4 and 5 consist of a deflection roller 7, which extends over the full width of the paper, and each of groups of friction rollers.
  • the feed channel 4 for single sheets 1 is formed from the deflecting roller 7 and a first group of friction rollers 8 and the feed channel 5 for single sheets 1 from the said deflecting roller 7 and a second group of friction rollers 9.
  • a feed shaft 11 formed from guide ribs 10 is also connected upstream of the feed channel 5. After lowering the second group of friction rollers 9, the functionally independent feed channel 6 for endless webs 2 is created, which are inserted into the feed channel 6 from a push tractor 12 which is freely accessible from above.
  • a printing station 14 which consists of a matrix needle print head 15 and a platen 16. Both single sheets 1 and endless webs 2 are transported out in the paper transport direction 13 by a friction drive 17 arranged downstream of the printing station 14, which can consist of a pair of friction rollers or a driven friction roller with associated pressure arms 17a.
  • the deflection roller 7 has a larger diameter than the friction rollers of the first group 8 and the second group 9 due to the formation of the feed channel. Design details can be changed by the choice of the diameter of the deflection roller 7.
  • the first group of friction rollers 8 can be swiveled out and the second group of friction rollers 9 can be lowered.
  • the friction roller axes 8a and 9a and the axis of the deflection roller 7 run parallel to one another on a printer base plate 18 (with side walls, not shown).
  • the switch axes 21 and 22 are rotatably mounted several times in the printer base plate 18.
  • Support springs 24 are attached to the hubs 23 of the friction roller axles 8a at intervals.
  • a cam projection 19 bears against each support spring end 24a.
  • the second group of friction rollers 9 is supported with a plurality of coaxial partial axes 25 on leaf springs 26 arranged at intervals, the first leaf spring ends 26a resting on a fixed support bearing 27 and the second leaf spring ends 26b resting on the cam cams 20 of the switching axis 22.
  • the shift axles 21 and 22 (FIGS. 4 to 7) each have a pair of eccentric pins 29 and 30 on a shift axle end 28. These engage in a push rod 31.
  • the push rod 31 is movably held in a guide of the printer base plate 18.
  • the eccentric pin 29 forms a link bearing together with the push rod 31, the switching axis end 28 being pivotable about a central axis 32 of the eccentric pin 29.
  • the other eccentric pin 30 moves in a free groove 33.
  • the second group of friction rollers 9 is also raised with the friction roller axis 9a and the employment of the second group of friction rollers 9 is carried out on the deflection roller 7, i.e. feed channels 4 and 5 are formed for the "single sheet feed" mode.
  • the push tractor 12 is driven by a tractor shaft 34 and an electric motor, not shown.
  • the electric motor carries a pinion 35.
  • a gear 36 is resilient on the tractor shaft 34 axially displaceably mounted, which meshes with the pinion 35 in the engaged state (FIGS. 6 and 7), so that the tractor shaft 34 is driven, ie the operating mode "endless web feed” is set.
  • a coupling axis 37 is mounted perpendicular to the tractor shaft 34, and cams 38 are attached to the shaft shaft 37a thereof against the tractor gear wheel end face 36a.
  • a spring 39 presses the gear wheel 36 in the direction against the shaft shaft 37a until it rests on a locking washer 47.
  • a toothed pinion 41 is fastened to the coupling axis end 40 and engages in a spur toothing 42 which forms part of the push rod 31.
  • the coupling axis 37 carries a hand rotary knob 43 at its upper, free end 37b. The respective operating modes can thus be set via the hand rotary knob 43, the coupling axis 37 being rotated from the position shown in FIGS. 4 and 5 to the positions in FIG 6 and 7, in which the cams 38 are ineffective, can engage the gear wheel 36 so that the drive of the pinion 35 is transmitted to the tractor shaft 34, ie the operating mode "continuous web feed" is set.
  • FIGS. 4 and 5 The position with the gear 36 disengaged (FIGS. 4 and 5) thus corresponds to the "single sheet feed” mode.
  • An automated embodiment (FIGS. 4 to 7) shows that the pinion 41 attached to the coupling axis end 40 engages in an output gear 44 of a gear unit 45 with a gear motor 46.
  • This geared motor can therefore be controlled accordingly via electrical signals in order to set either the "single sheet feed” or "endless web feed” operating mode.
  • an alternative invention consists of an interim solution.
  • This intermediate solution is designed according to FIG. 8. It is provided here that the deflecting roller 7, which is arranged in the paper transport direction 13 in front of the printing station 14 and extends in length across the paper width, has a pressure-changing first group of friction rollers 8 for a first feed channel 4 and a second group of friction rollers 9 offset on the circumference. which can be raised and lowered are assigned. When the first group of friction rollers 8 is pressed on with a reduced pressing force and when the second group of friction rollers 9 is lowered, a feed channel 6 for endless webs 2 is formed together with the deflecting roller 7.
  • the endless webs 2 can be displaced by means of the push tractor 12 and can be conveyed out by means of the friction drive 17 arranged downstream of the printing station 14.
  • the first group of friction rollers 8 are assigned the support springs 24 or the support spring ends 24a with a base plate 24b.
  • the support springs 24, the base plate 24b, the friction roller axles 8a and the support spring end 24 are all made from one piece of plasticizable plastic.
  • a spring pin 48 is provided on the base plate 24b - also in one piece.
  • the compression spring 49 is tuned in such a way that either a stronger or a weaker contact force acts on the first group of friction rollers 8.
