Definitions

  • the invention relates to a device for pressing a stack of sheets onto the roller drive of a device for single sheet removal, with a pressure plate loaded by a compression spring and pivotably mounted on one side as the bottom-side carrier of the sheet stack in a cassette.
  • the invention has for its object to design a device of the type mentioned so that it enables the trouble-free deduction of sheet types with different paper thicknesses and formats and also form sets and envelopes.
  • a particularly advantageous embodiment of the invention is characterized in that the compression spring on a sled which is displaceable perpendicular to the shaft axis of the swivel loader of the pressure plate is fastened such that the effective lever arm between the swivel loader and the point of application of the spring is changed with the adjustment of the slide.
  • the contact pressure of the spring can also be changed with the adjustment of the slide.
  • two or more pressure plates at least one of which is equipped with a device for changing the contact pressure and is slidably mounted sideways.
  • a cassette-shaped receptacle has holes in the side wall 1 for receiving the shafts 2 and 3.
  • the side wall 7 is attached to the base plate 8 in an angularly rigid manner.
  • a support plate 10 and a pressure plate 11 are displaceably mounted on the shaft 3 while the bearings 9 are switched on.
  • the bearings 9 are held in place by self-contained nipples, e.g. made of plastic.
  • the carrier plate 10 and the pressure plate 11 can be pivoted relative to one another independently of the shaft 2 about the bearings 9.
  • a prestressed leaf spring 12 is arranged between the parts 10, 11, which in turn is fastened to a slide 13 and rests with the free end 14 against a rib 15 and thus against the pressure plate 11. If the slide 13 is tilted around the edge 16 by pressing on the part 17 against the force of the leaf spring 12, the locking cams of the slide 13 can be pressed out of the recesses 18 and then the slide 13 can be moved along the slot-shaped guide 19.
  • the carrier plate is opposed to the shaft 3 by the part 20 in contact. a shift locked.
  • the pivoting of the shaft 3 can be carried out by means of a lever which is attached to the shaft 3 at a laterally rigid angle.
