Definitions

  • the invention relates to a device for changing a stack of sheets formed on a transport element in a sheet delivery with continuous sheet feed according to the preamble of claim 1.
  • a triangular and a rectangular slide are provided, which are inserted one after the other by hand to separate an upper part of the stack from its end face.
  • a joint is formed by hand for the tip of the triangular slide to be inserted first, so that its insertion is facilitated and no leading edges of the bow are damaged.
  • a device for changing a stack in a sheet delivery is known (DE-OS 29 42 965), which consists of a rake that can be inserted in the conveying direction of the sheet between the top of the stack and the sheet lying thereon. So that this process can be carried out without damaging the sheets, the rake has blow nozzles on its front sides.
  • such a device is not suitable for separating sheets that have already been stacked, because the individual tines on the rake do not guarantee that they will be inserted between the same sheets. The tines cannot be inserted into the stack without damage on the end face. The air jets emerging from the tines are unable to form a defined gap between two identical arches on the entire end face.
  • the invention has for its object to provide a device for changing a sheet stack formed on transport elements in a sheet delivery, with which a stack change can be carried out quickly without manual help and without risk of damage to the sheets.
  • the separation does not begin in the middle of the front edge of the stack, but at a corner of the stack with the aid of air.
  • the stack can still be lifted slightly at such a corner.
  • the air-lubricated cutting edge attached to one edge provides greater functional reliability compared to a triangular cutting edge attached centrally to the front edge of the stack.
  • the material web 1 is divided into sheets by a cross cutter with an upper cutter roller 2 and a lower cutter bar 3, which are fed to a sheet delivery unit via a suspension table 4.
  • the sheet delivery comprises a conveyor roller 5, conveyor rollers 6, cam disks 7, suction table 8 for overlapping and braking, and a floating ceiling 9, under which the sheets are guided up to the leading edge stop 10, where they are a continuously increasing stack 11 on a controllable height Form pallet 12.
  • a sleeve 14 with an angled support arm 15, at its angled part in a flat slide 17 is mounted on both sides of the telescopic guides 16.
  • On the sleeve 14 is another non-pivotable sleeve 18 with a simple arm 19 which has a telescopic guide for the leading edge slide 20.
  • the surface slide 17 is brought into the drawn working position by a pivoting movement A of the support arm 15 around the column 13, which the edge slide 20 accordingly achieves through a small stroke B.
  • the stack change is initiated by the stroke C of the edge pusher 20.
  • the necessary safe separation is achieved by air lubrication.
  • FIG. 4 shows from the view RS of FIG. 3 how two round jets from the nozzles 21 in front of the knife edge 22 form the flat jet, which lifts a small sheet packet 24 from the vertical stacking edge 23.
  • the edge pusher 20 can now easily separate a small sheet package 24 by the stroke C mentioned (FIGS. 5 and 6).
  • the stack 11 is lowered somewhat, which creates a gap D (FIG. 7).
  • the surface slide 17 is inserted by the arc length E ( Figure 8).
  • the pallet 12 with the stack 11 carried by it is lowered to the bottom 25 by the dimension F, and a new pallet 12a is pushed by the dimension G into the position which the full pallet 12 leaves in the process (FIG. 9).
  • the new pallet 12a is brought under the surface slide 17 with the stroke 1.
  • the lifting movements are carried out in reverse order E, D, C, B, A, whereby the stack change is finished and the full stack 11 can be removed on the pallet 12.
  • Fig. 5 shows how cone nozzles 26, e.g. according to DE-OS 39 36 846, are let in and blow an air cushion into the gap between sheet package 24 and stack 11. These nozzles are arranged in two staggered rows on the top and bottom of the surface slide 17 ( Figure 3).
  • the stack 11 can also be formed, separated and removed on a lifting and lowering conveyor table 27, the height of the stack 11 being adapted to further processing, e.g. handling transport on air cushion tables 28.
  • Figures 1 and 2 show the surface slide in the direction of the thrust coinciding with the conveying direction.
  • two edge slides each have the outer sides of the two stacks with a direction of thrust against the conveying direction, while two surface slides, perpendicular to the conveying direction, penetrate from below under the edge sliders to hold the two upper parts of the stack for the duration of the stack removal.
  • the sliders are equipped with telescopic guides on arms that are attached to sleeves.
  • the sleeves are also provided with an automatic lowering mechanism. The stacks can be formed, exchanged and removed without manual intervention.
