Definitions

  • the invention relates to a device for dividing a stream of shingles from superimposed benefits into two partial streams formed by lifting with two conveyors in the form of conveyor belts.
  • the further known CH-PS 663 604 relates to a deflection device for a shingled stream, in particular of booklets or sheets to be transported in a shingled position (benefit).
  • a deflection device for a shingled stream in particular of booklets or sheets to be transported in a shingled position (benefit).
  • Several conveyor lines are connected.
  • a section is designed as a switch and can be folded down and switched in the conveying direction. This can be used, for example, to deflect the scale flow by 180 °.
  • the second conveyor belt which is adjacent to the surface of the panels and is provided with a perforated perforation which can be subjected to negative pressure, is provided and that the directions of transport of the conveyor belts form an acute angle to one another.
  • the distance between the two conveyor belts is expediently adjustable. It should expediently be set so that it is slightly larger than the height of the superimposed benefits, so that on the one hand they can easily get between the conveyor belts, but on the other hand the upper benefit can be easily sucked in.
  • the lower conveyor belt is at least twice as wide as the upper one and the upper conveyor belt is arranged completely or at least within the width of the lower conveyor belt with the area in which the perforated perforation is subjected to negative pressure. It is thereby achieved that the upper panel, after it has been displaced laterally, is deposited again on the lower conveyor belt, so that the two panels can finally be transported next to one another and stacked.
  • the lower conveyor belt has a perforation in the part of its width where the upper conveyor belt begins. This draws in the bottom panel so that it cannot be easily moved; the upper panel, however, is not sucked in by the lower conveyor belt because it lies on the lower panel, so that it can be moved laterally by the upper conveyor belt.
  • the upper benefit lies to an increasing extent directly on the lower conveyor belt, but this does not normally have perforated holes there, so that the lateral movement is not hindered. If there is a perforation in the hole to fix the upper panel on the lower conveyor belt after moving it laterally, the perforation should be in the area of the upper one Do not apply negative pressure to the conveyor belt so that lateral displacement is not hindered.
  • the speed of the upper conveyor belt is advantageously adjustable in relation to that of the lower conveyor belt.
  • the speed is set depending on the extent to which the superimposed benefits overlap with the next superimposed benefits. The more they overlap, the faster the upper conveyor belt should move so that the upper panels lie on the upper conveyor belt with a sufficiently large area.
  • FIG. 1 shows a schematic top view of the device according to the invention
  • FIG. 2 shows a sectional view along the line II-II in FIG. 1
  • FIG. 3 shows a bottom view of the upper conveyor belt
  • FIG. 4 shows a sectional view along the line IV-IV in FIG 1 and 5 a top view of the lower conveyor belt.
  • the device according to the invention essentially consists of a lower conveyor belt 1 and an upper conveyor belt 2, the directions of transport of the two conveyor belts enclosing an acute angle with one another. 2 and 3, the perforated upper conveyor belt 2 is guided over deflection rollers 3, which are mounted in a base frame G and one of which is driven by a potentiometer-controlled gear motor 4. In order to avoid slippage of the conveyor belt 2, a pressure roller 5 is provided which presses against the driven deflection roller 3. In the space enclosed by the conveyor belt 2, a vacuum box 6 having two suction openings 7 is arranged.
  • a suction box 10 having a suction opening 13 is arranged in the space enclosed by the conveyor belt 1.
  • the upper panel 11 is lifted off the upper conveyor belt 2 due to the suction effect exerted by it and transported laterally away.
  • the lower panel 12 remains on the latter due to the suction effect exerted by the lower conveyor belt 1.
  • the upper panel 11 is placed laterally offset on the lower conveyor belt 1.
