Definitions

  • Such a method provides for the trouble-free deposition of the sheets arriving via an overlapping sheet run or path and the stacking of the sheets in a smooth, straight-edged arrangement, with the compressed air cushion in conjunction with the conveyor means above the stack effecting advantageously a rapid and trouble-free separation of the leading sheet from the remainder of the sheet run as well as the rapid deposition of the separated sheet onto the stack.
  • the sheet run still moving forwardly is pressed against the conveyor means above the stack, whereby the sheet run, and thus the individual sheets, is brought positively into the correct position for deposition.
  • the present apparatus includes essentially a stack holder, known per se, having a rear, stationary boundary 3,224,761 Patented Dec. 21, 1965 wall, lateral boundary walls and a front boundary wall preferably including a shaking member for straightening the stack.
  • a blower acting in the direction of movement of the sheets is located directly ahead of the stack holder and a conveying means above the stack holder extends the entire length of the stack holder.
  • the conveying means consists of several endless belts guided over rollers with the rollers directly ahead of, and those directly behind the front edge of the stack being offset relative to each other in such a fashion that the conveyor belts receive a slight offset in the front zone of the stack.
  • the rear wall of the stack holder is provided with cut-out areas through which the individual belts of the conveying means pass.
  • FIGURE 1 is a view in side elevation, partly in cross section and partly broken away, illustrating an apparatus embodying the invention
  • FIGURE 2 is a sectional view taken along the line 2-2 of FIGURE 1, the view looking in the direction of the arrows, and
  • FIGURE 3 is a sectional view taken along the line 3-3 of FIGURE 1, the view looking in the direction of the arrows.
  • the conveyor means consist of a plurality of spaced-apart belts 3a, 4a each having upper and lower flights and rollers 6, 7, 8, 9 and 10 serve to guide the upper and lower conveyor belts.
  • the stack holder 5 includes a rear, stationary boundary wall 11 and, as clearly illustrated in FIGURE 3, the wall 11 is provided with a plurality of cut-out areas or notches 12 through which the plurality of belts 3a are adapted to pass.
  • Side walls (not shown) bound the longitudinal sides of the holder 5 and front wall 14 is provided at its upper area with a shaking or agitating member 13.
  • a conveyor table 15 is located between the roller 9 of the lower conveyor means 4 and the roller 10.
  • the roller 10 is so located relative to the roller 7 that there is produced an offsetting or deflection of the upper conveyor belts 3a and, as a consequence, the sheet run 2 in the front zone or area of the stack holder 5.
  • a plurality of blast nozzles 16 which are supplied with compressed air from a common air conduit 17 which extends transversely of the apparatus, are located directly in front of and above the front wall of the stack holder 5, as shown in FIGURE 1.
  • the rear edge is located in the zone of the offsetting or deflection of the upper conveyor belts 3a determined by the roller 7, which causes such end of the leading sheet to lift somewhat away from the underside of the run 2 and thus provide a gap or space.
  • a compressed air cushion is built up between the leading sheet 1 and the sheet run 2.
  • the compressed air cushion effects an accelerated depositing of the sheet 1 which is now separated from the run 2, and the air cushion simultaneously causes a holding of the still forwardly moving run 2 against the upper conveyor belts 3a until the forward movement of the now leading sheet 1 is stopped by the rear wall 11 when such sheet will be separated from the run and deposited into the holder 5.
  • An apparatus for depositing overlapping sheets emanating from across cutter and other paper processing machines comprising a stack holder, upper and lower conveyors for moving the overlapping sheets to said stack holder, said upper conveyor extending above the entire longitudinal length of said stack holder and including a plurality of endless belts having upper and lower flights and axially spaced guide rollers for said belts, one of said guide rollers being located above the stack holder and having its periphery so located with respect to the periphery of another of said guide rollers in advance of the stack holder so as to deflect the lower flights of the belts downwardly adjacent the front of the stack holder to produce a gap between the rear edge of a leading sheet and a trailing sheet, and at least one fluid nozzle located in front of the stack holder below the lower flights of the belts for directing fluid into the gap to separate the sheets and deposit the leading sheet into the holder while holding the sheets still moving forward against the lower flights of the endless belts above the stack holder.
  • An apparatus for depositing overlapping sheets emanating from a cross cutter and other paper processing machines comprising a stack holder, upper and lower conveyors for moving the overlapping sheets to said stack holder, said lower conveyor terminating in advance of the front of the stack holder, a table located between the lower conveyor and the front of the stack holder, said upper conveyor extending above the entire longitudinal length of said stack holder and including a plurality of endless belts having upper and lower flights and axially spaced guide rollers for said belts, one of said guide rollers being located above the stack holder adjacent the front of said holder, the periphery of said one guide roller being so disposed with the periphery of another of said guide rollers forwardly of the stack holder as to offset the lower flights of said belts downwardly adjacent the front of the stack holder to produce a gap between the rear edge of a leading sheet and a trailing sheet, a compressed air conduit extending transversely relative to the upper conveyor in front of the stack holder, and a plurality of nozzles carried by said
  • said stack holder includes a rear wall having a plurality of cutout areas through which the lower flights of said endless belts are adapted to pass.
