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, with foldable components being fastened by means of spherical bearings.
  • Such transport devices are used for line-by-line, step-by-step or continuous feed of record carriers, which e.g. consist of paper webs.
  • record carriers which e.g. consist of paper webs.
  • the tractor hatches i.e. Swing covers that hold the paper web on the pins away.
  • the tractor flaps are therefore held in swivel bearings so that they can be swung out.
  • the swiveling-in of foldable components that are pivoted out during operation is advantageous in order to save transport and packaging space.
  • the invention is therefore based on the object of creating a simple articulated bearing for foldable components on printers and also a simple locking device for the foldable positions.
  • a cut spring steel wire piece is used as a hinge pin and for fixing a closed or open position of the flap component, which is put under tension by curvature.
  • a preferred embodiment of the invention is designed in such a way that on the tractor body spaced-apart tractor bearings are provided, in which the ends of the spring steel wire stucco are mounted, and that at least one valve component bearing with a through hole for the spring-standing wire piece is provided on the valve component between the tractor bearings of the tractor body is that, in addition, in the closed and open position, the flap component bearing (s) bear with outer, flat surfaces on a flat counter surface of the tractor body and that the bores in the tractor bearings and in the flap component bearing differ in their axes.
  • a functionally reversed design of this solution consists in that flap component end bearings, in which the ends of the spring steel wire piece are mounted, are provided on the flap component in the feed direction.
  • the tractor body between the flap component end bearings at least one tractor bearing with a through hole for the spring steel wire piece is provided that in addition in the closed and open position, the flap component parts bearings rest with flat outer surfaces on a flat counter surface of the tractor body and that the through holes in the tractor bearings and in the valve component end bearings differ in their internal axis.
  • Falling out of the spring steel wire piece can be avoided by crimping the ends of the spring steel wire piece.
  • the application of the invention to a matrix printer results from the fact that the flap component consists of a cover flap for the belt band of the tractor device.
  • the flap component consists of a lateral guide flap for the record carrier.
  • Fig. List drawn without the Aufzechchnungani.
  • the transport device shown is arranged in pairs to the left and right of the record carrier.
  • Fig. List the left tractor device la and in Fig. 2, the right tractor device 1b visible, both tractor devices 1a, 1b are guided on a mounting rod 2 and a drive shaft 3, which themselves are set exactly in parallel by side bracket 4 and adjusting screws 5.
  • the fastening rod 2 runs in FIG. 1 through the bore 2a and the drive shaft 3, which is square in cross section, runs through a square bushing which is inserted in the bore 3a.
  • the drive axle 3 is in this case rotatably supported in the bushing 6 fastened in the side carrier 4.
  • the Aufzelchnugesel is at one point on the wings 7 of the baffle flap 8 and later at another location on the support 9.
  • 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, i.e. is under tension. 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 16u.
  • At least one tractor bearing (16a or 16b) centrally attached to the tractor body 16 is provided and the flap component 10 in question has bearings (10a; 10b) on its flap component parts.
  • the spring steel wire piece 18 is crimped at its ends 18a, 18b to prevent it from falling out.
  • the flap component 10 can in each case be placed upright, ie 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 over the Hiemenband 15 as well as for the lateral Leitwandklappe 8 for the recording medium and any at all K lappbau tone a printer, in particular a M d trix horrers be employed.
