Definitions

  • the invention relates to a single sheet collecting device for stacking of sheets of paper, plastic and the like according to the generic term of claim 1.
  • Sheets that are to be stacked into sets are classified according to the feed direction stacked over or under.
  • the sheets with With the help of the transport elements, which are preferably designed as round belts passed over the overrun device and on a stop unit stopped.
  • the next arc is then again over the Ramp unit guided and on the next sheet or under this placed or pushed. So the stacks of ten and more Leaves formed.
  • the complete is transported until it leaves this unit.
  • the stop unit is then stopped again for a subsequent one To form stacks.
  • An offset often occurs when large stacks are formed the bow instead.
  • When starting the stop unit it happens then before that one or more sheets against each other during further transport be moved or even stay because they are not have been correctly recorded. This occurs especially when Drive the stop unit a servo motor is used in which the stop unit is exposed to high accelerations.
  • the invention has for its object a device of the generic type Kind in such a way that the Avoid stacking misalignment or individual sheets becomes.
  • the contact pressure is selected so that a displacement of the individual sheets when the Stack is prevented on the one hand, but also at high Accelerations of the respective set perfectly from the sling unit can be transported further.
  • arcs 2 preferably sheets of paper, collected or stacked into sets, which then in a post-processing device (not shown) be processed further.
  • the one forming an accumulator Device 1 has drive rollers 3 on the input and output side to 6, of which only the roles on the output side are shown are.
  • Transport belts 7 to 12 run over the rollers 3 to 6 are preferably designed as a round belt.
  • P aligned roles are provided, of which only each external rollers 3, 4 and 5, 6 can be seen.
  • To each other aligned roller pair is a conveyor belt 7 to 12 out.
  • the upper and lower rollers 3, 4 and 5, 6 are equidistant from each other.
  • the distance between the upper rollers 3, 4 is however larger than that between the lower rollers 5, 6.
  • the middle (not shown) roles are aligned, while the lateral lower rollers 5 and 6 compared to the upper outer Rolls 3 and 4 are offset inwards.
  • Stop rollers 13, 14 and 15, 16 which is an adjustable stop unit form for the paper sheets 2.
  • the rollers 13, 14 are above and the rollers 15, 16 below the transport plane, the rollers 13 and 15 and the rollers 14 and 16 are one above the other.
  • Fig. 2 In view according to Fig. 2 are the roles 13, 15 and 14, 16 between the (not shown) middle rollers and the lower side rollers 5 or 6.
  • the rollers 13, 15 and 15, 16 have a smaller distance from them than from the middle rollers on which the conveyor belts 8 and 11 run.
  • the upper and lower rollers 13, 14 and 15, 16 are can be driven in opposite directions in a known manner and stand during the Stacking the sheets of paper 2 silently.
  • the stop rollers 13 to 16 are in the stop position shown in Fig. 1 to each other. Thereby can the paper sheets fed with the conveyor belts 7 to 12 2 not transported further between the stationary stop rollers 13 to 16 become.
  • the paper sheets 2 are on the stop rolls stopped and stacked.
  • Fig. 1 As can be seen from Fig.
  • a casserole 17 which in is known as a ramp.
  • side view 1 has approximately trapezoidal shape and has one in the transport direction P on flat ramp surface 17a, which rises in the front Transport path of the paper sheet 2 lies and ensures that it is in the area before the stop rollers 13 to 16 with elastic deformation of the Transport belts 7 to 12 are raised.
  • the overrun device 17 consists of several, in the area between the conveyor belts 7 to 12 arranged wedge elements, so that the paper sheet 2 can be reliably raised across its width.
  • the upper pressure roller 18 is transverse to the transport path force-loaded.
  • the lower pressure roller 19 serves as an abutment when the upper pressure roller 18 on the formed in front of the stop rollers 13 to 16 Presses stack 22 from sheet of paper 2.
  • the upper pressure roller is advantageous 18 spring loaded. But you can also, for example, with a Actuator against the transport level.
  • the pressure rollers 18, 19 are made of a material with little Coefficient of friction, preferably made of steel.
  • the pressure rollers 18, 19 are in the level of the middle (not shown) transport rollers. she have as the rollers 3 to 6 a circumferential groove 20, 21 for the middle conveyor belt 8 or 11.
  • the depth of the grooves 20, 21 is larger than the diameter of the conveyor belts 8, 11, so that these are completely sunk in the grooves. This only comes the pressure rollers 18, 19 in contact with the paper sheets 2.
  • the axes the transport rollers 3 to 6 are parallel to each other and are during the passage of the paper sheets 2 unchangeable.
  • the axes of the lower stop rollers 15, 16 and the lower Pressure roller 18 are unchangeable.
  • the upper stop rollers 13, 14 and the upper pressure roller 18, however, are transverse to the transport plane movable so that these rollers 13, 14, 18 to the respective height of the paper stack 22 can adjust.
  • the pressure rollers 18, 19 lie in the area between the stop rollers 13 to 16 and the overrun device 17 and exert on the stack 22 the paper sheet 2 a print, without the stack is hindered during subsequent transport. Because of this pressure The sheets of paper do not slip against each other when the stack 22 further after the stack formation by the stop rollers 13 to 16 is transported. This makes it easy to get thick Transport stack without unwanted misalignment of the paper sheets 2. This is especially true when the stop rollers 13 to 16, for example, accelerated quickly via a servo motor become.
  • the first sheet of paper with the conveyor belts 7 to 12 in the stop position carried on the stationary stop rollers 13 to 16 (Fig. 1).
  • the upper pressure roller 18 presses on the paper sheet 2, which thus reliably transports to the stop rollers 13 to 16 becomes.
  • the pressure rollers 18, 19 are different for adaptation to long sheets of paper 2 advantageously adjustable in the direction of transport P.
  • the overrun device 17 is set so that the paper sheet 2 in its stop position with its rear edge 25 in front of one vertically extending end face 26 of the overrun device 17.
  • the overrun device 17 is also different for adaptation to long sheets of paper 2 advantageously adjustable in the direction of transport P.
  • the upper pressure roller 18 loads the stack 22 so that it from the Stop rollers 13 to 16 are correctly detected and taken without that the paper sheets 2 accidentally slip against each other. If the contact force of the pressure roller 18 is adjustable, the contact pressure can be optimally adjusted to the thickness of the stack 22.
  • the Contact pressure is set so that on the paper sheet 2 of the stack 22 an increased pressure force acts to prevent unwanted displacement to prevent the paper sheet 2 against each other, but on the other hand when the stop rollers 13 to 16 approach, the further transport of the stack 22 is not hindered.
  • the paper sheet set 22 can also be stacked under the paper sheets 2 are formed, the overrun device such a position assumes that the subsequent sheet of paper 2 under the each previous paper sheet 2 are placed. In this case, exercise the lower pressure roller 19 exerts a force on the stack 22 while the upper pressure roller 18 forms a counter bearing.
