Definitions

  • the invention relates to a transport device for printers, in particular for matrix printers, which are provided with paired tractor devices for guiding and / or advancing the record carrier, a flap component being fastened by means of joints formed by flap component bearings and tractor bearings.
  • the tractor hatches i.e. Swing covers that hold the paper web on the pins away.
  • Tractor flaps are therefore swivel-mounted.
  • a flap component fastening of the generic type is known from DE-A-1 524 445.
  • the flap components there are the paper pressure flaps on the tractors, are each held in a pivoted-down position or in contact with the tractor by means of a pretensioned bow spring which engages a hinge-like extension of the flaps, the tension of the bow spring being changeable by two displaceable clamping pieces.
  • the invention has for its object to provide a simple spherical bearing for flap components on transport devices for printers, in particular matrix printers, and also a simple locking device for the flap positions.
  • FIG. 1 the left transport device 1a and in Fig. 2, the right transport device 1b is shown, wherein both transport devices 1a, 1b are guided on a mounting rod 2 and a drive shaft 3, which are themselves set exactly in parallel by side supports 4 and adjusting screws 5.
  • the Fastening rod 2 runs through a bore 2a in FIG. 1 and the drive shaft 3, which is square in cross section, runs through a square bushing which is inserted into a bore 3a.
  • the drive axle 3 is in this case rotatably supported in a bushing 6 fastened in the side carrier 4.
  • the record carrier rests on wings 7 of a guide flap 8 and on a support 9.
  • FIGS. 1 and 2 have hinge bearings 11 for their flap components.
  • the flap component 10 there consists of a cover flap 12 and, according to FIG. 2, the flap component 10 consists of the guide flap 8. While the guide flap 8 can be swiveled in in the direction 13 for transport or packaging purposes of the printer, the swiveling up and swiveling in of the tractor flap 12 serves to insert the perforated recording medium, ie the perforated paper web. The paper web is inserted with its perforation into the pins 14 of the belt band 15, which is guided in the tractor body 16. The cover flap 12 is then pivoted from the illustrated vertical position into the horizontal position in which it covers the belt band 15.
  • the spherical bearings 11 are designed as described below:
  • the spherical plain bearings 11 have pivot pins 17 in the form of cut spring steel wire pieces 18.
  • the tractor body 16 Provided on the tractor body 16 are the tractor bearings 16a and 16b which are spaced apart in the feed direction 19 and in which the ends 18a and 18b of the spring steel wire piece 18 are mounted.
  • the flap component 10 carries two flap component bearings 10a and 10b, each with one Through hole 10c are provided.
  • the spring steel wire piece 18 runs in the through bores 10c.
  • the flap component bearings 10a and 10b have outer, flat surfaces 10d which are supported on a flat counter surface 16c of the tractor body 16, the spring steel wire piece 18 running slightly curved, that is to say being preloaded. This preload is achieved by an offset of approximately 0.8 mm between the axes of the through bores 10c and the bores 16d in the tractor bearings 16a and 16b.
  • At least one tractor bearing 16a or 16b is attached centrally to the tractor body 16 and the relevant flap component 10 has bearings 10a, 10b on its flap component parts.
  • the spring steel wire piece 18 is crimped at its ends 18a, 18b in order to avoid falling out of the bearings.
  • the flap component 10 is in each case upright, i.e. can be placed vertically and fixed.
  • the outer, flat counter surface 16c of the tractor body 16 extends at 90 ° to corresponding surfaces 10d of the flap component bearings 10a, 10b.
  • This principle can be used both for the cover flap 12 above the belt band 15 and for the side wing flap 8 for the recording medium and as desired on all flap components of a printer, in particular a matrix printer.
