Definitions

  • the invention relates to a device for loading an office machine, in particular a typewriter with single sheets, according to the preamble of claim 1.
  • the object of the invention is to further develop such a device in such a way that it can be made more compact, a simpler separation of the sheets and easy adaptation to different machine makes with different paper widths is possible.
  • the device is used to feed single sheets or several sheets combined into a set to an office machine, for example a typewriter or printer, in which machine the sheets are labeled or printed in the usual way.
  • the sheets lie in the form of a supply stack 6 on two rockers 2 arranged in parallel and are fed to a platen roller 3 by two drivable pull-off rollers 15.
  • the labeled sheets then pass between two transport rollers 4, 5 and are finally placed on an inclined stack 7.
  • the two rockers 2 are seated on a rocker shaft 9 which is designed as a square cross section and which is rotatably mounted in the two side walls 8.
  • the rockers 2 can be fixed on the rocker axis 9 by screws 11.
  • the square shape of the rocker axis 9 ensures that both rockers 2 perform a synchronous pivoting movement.
  • Each of the two lateral, vertical boundary walls 12 contains an upwardly opening slot 16, which is penetrated by the drive shaft 14 for the take-off rollers 15. The rockers 2 can thus pivot without this influencing the position of the pull-off rollers 15.
  • Each of the spacer bushes 46 seated on the drive shaft 14 engages with its radial groove 42 with play in the slot 16 and is rotatably connected to the take-off roller. This allows the rocker 2 to be moved along the rocker axis 9 and at the same time the pull-off roller 15 is also displaced.
  • a profile plate 19 is pivotally connected to the rocker 2. This is mounted in a pivot axis 24 in the rear third of the rocker 2 and contains a stop 18 at the front for the supply stack 6, which merges into a guide plate 20 at the top.
  • the guide plate 20 extends approximately parallel to the supply stack 6. The position of the guide plate 20 is chosen relative to the circumference of the draw-off roller 15 such that the top sheet of the supply stack 6 is approximately at the same height as the upper edge of the guide plate 20.
  • the stop 18 and the guide plate 20 together form a right angle.
  • each rocker 2 is provided with a triangular separating corner 28, which projects above the supply stack 6 at opposite corners, as can be seen in particular from FIG. 4.
  • Each separating corner 28 sits on the bent part 44 of a swivel plate 26 and forms a single piece.
  • the pivot plate 26 is pivotally mounted about an axis of rotation 30 parallel to the rocker axis 9.
  • the arrangement of this swivel plate 26 on the two rockers 2 is a mirror image.
  • each rocker is provided with a U-shaped bracket, which is designed to be removable and can also be pushed in parallel to the rocker base 13 when not in use.
  • the take-off rollers 15 are each provided with an overrunning clutch, not shown, so that they can rotate freely on an uppermost sheet pulled off in the direction of arrow C without the drive shaft 14 also rotating.
  • the two side walls 8 of the device are connected to one another by struts 10.
  • the design is preferably such that the movement derived from the platen roller 3 is transmitted to the drive shaft 14 by toothed belts with the interposition of a gear with an interrupted movement.
