Definitions

  • the invention relates to a device for stacking sheets, in particular shingled sheets of paper, with a vertically movable storage platform and an auxiliary stacking platform that can be moved horizontally into the stacking area by means of a travel drive.
  • the stacking device For stacking sheets of paper a generic device is known from EP-B 0 31 6 568 with which a change of a full stack can be carried out without having to interrupt the supply of the sheets to the stacking point or to remove sheets.
  • the stacking device has an auxiliary stacking platform which can be moved into the stacking area in order to hold the upper part of the stack while the lower part of the stack is being transported away.
  • the auxiliary stacking platform consists of a trolley of low height, which is rotated in the conveying direction by a low-friction cloth and can be moved horizontally by means of a travel drive. So that it can be inserted into the stack, a gap is previously formed between the trailing edges of the sheet.
  • the auxiliary stacking platform was formed by a solid steel plate, which must be made so stable that it is able to support the weight of the upper one
  • the invention has for its object to provide a stacking device with an auxiliary stacking platform which can be moved into a stack with little friction, has as little weight as possible and can be easily adapted to different lengths of the storage platform.
  • the auxiliary stacking platform has two longitudinal beams which are arranged at a distance from one another and extend horizontally in the direction of sheet travel, to which a number of transverse lamellae made of a flat hollow profile are fastened next to one another, which are connected to a compressed air supply and one on their top Have row of air outlet openings.
  • Figure 1 shows a side view of a stacking device with the auxiliary stacking platform according to the invention.
  • FIG. 2 shows the auxiliary stack platform in a perspective, partially sectioned view.
  • FIG. 3 shows an enlarged section X from FIG. 2.
  • Figure 4 shows a longitudinal section through the area of the entry tip.
  • the device shown in FIG. 1 is used to deposit scaly paper or cardboard sheets 1 onto a stack 2 which is formed on a pallet 3.
  • the pallet 3 lies on a vertically movable storage platform 5 in the rack 4 of the stacking device, which is continuously lowered during stacking in such a way that the top of the stack 2 is kept at a constant small distance from the feed plane 6 of the sheets 1.
  • the known stack formation elements (side shaking plates 7, stop boards 8) are arranged in the region of the stack 2.
  • an auxiliary stacking platform 9 which can be moved into the stacking area, is arranged on the inlet side, onto which stacking takes place while a finished stack 2 is being transported away. So that the auxiliary stacking platform 9 can be moved into the stack without upsetting or damaging sheets 1, a gap between the trailing sheet edges is first formed by a separating device 10.
  • the sheet pack located above the auxiliary stacking platform 9 is clamped and held by two clamping bars, each with a row of tongue-shaped clamp elements 11, 12, while the auxiliary stacking platform 9 is moved into the stack 2.
  • the auxiliary stacking platform 9 can be moved horizontally into the stacking area by means of a travel drive 1 3 and can be moved back out of it in a slide 14 which is suspended on the upstream stands 15 of the frame 4 and on which the clamp elements 11, 12 also horizontally so are stored so that they can be moved between the rear edges of the sheets 1 in the stack 2.
  • the structure of the auxiliary stack platform 9 is shown in more detail in FIGS. 2 to 4:
  • the auxiliary stacking platform 9 consists of two longitudinal beams 1 6, 1 7 made of a hollow profile with a rectangular cross-section, which extends horizontally in the carriage 14 on both longitudinal sides of the frame outside the maximum working width in the carriage 14. kend and by means of the travel drive 1 3 horizontally movable. On the top of the longitudinal beams 1 6, 17, a series of transverse lamellae 1 8 are fastened in succession from a flat hollow profile, which with their open
  • End faces are connected to air supply pipes 19, 20, which are mounted on the upper sides of the longitudinal beams 16, 17 and run parallel to them and are connected to a compressed air supply.
  • the air supply pipes 1 9, 20 consist of a U-profile open to the fins 1 8 or of a square pipe which is slotted on the corresponding side.
  • each lamella 1 8 has a row of nozzle-shaped air outlet openings 21 over its length, which - as shown in FIG. 4 - can be opened and closed in each case by means of a ball valve 22.
  • the ball 23 of a ball valve 22 is seated in a nozzle 24 which tapers conically towards the top and has side air inlets. It is pressed by a spring 25 into the closed position, in which its circumference protrudes from the top of the auxiliary stacking platform 9.
  • the lamellae 18 are covered by a thin cover plate 26, which has openings corresponding to the positions of the air outlet openings 21
  • the cover plate 26 forms a pointed edge 28 on the entry side, which enables problem-free entry between the trailing edges of the sheet in the stack 2. It is preferably low-friction on its top, e.g. coated with PTFE.
  • the covering of the lamellae 1 8 has the advantage that when entering the stack 2 the air cushion effect increases, which reduces the friction so that no upsetting or displacements of sheets 1 occur in the stack 2.
  • the stacking device works as follows: During stacking, the upper side of the stack 2 is kept at a constant height below the feed plane 6 by correspondingly lowering the depositing platform 5. If the preselected number of sheets is stacked, this runs first
  • Separating element 1 0 at the level of the feed plane between the sheet trailing edges. It then moves downwards with the stack 2 until the height of the lower clamp elements 12 is reached. It stops there, so that a further lowering of the stack 2 forms a gap below the separating element 10. The clamp elements 1 2 move into this gap. At the same time, the carriage 14 begins to move downwards in synchronization with the stack 2.
  • the separating element 10 is then moved out of the stack 2 again and moves up again in order to form a gap for the upper clamp elements 11 in a corresponding manner. After these are retracted between the trailing edges of the sheet, a sheet packet is clamped between the clamp elements 11, 12.
  • a gap is formed below the lower clamp elements 1 2, into which the auxiliary stack platform 9 is inserted.
  • the weight of the stack 2 presses the balls 23 of the valves 22 downward in the region covered by arches 1 and thus opens the valves 22. Compressed air emerges which is fed to the fins 1 8 via the pipes 19, 20.
  • the escaping compressed air creates an air cushion which minimizes the friction between the lowermost sheet 1 of the stack part lying thereon and the upper side of the auxiliary stacking platform 9.
  • the auxiliary stacking platform 9 now carries the upper part of the stack, while the finished stack 2 located below it is lowered onto the floor and transported away. After placing a new, empty pallet 3, the storage platform 5 is raised until the new pallet 3 is below the auxiliary stacking platform 9. If during the movement of the pallet 3 to the auxiliary stacking platform 9 damage, e.g. B. fear from upstanding nails, the underside of the slats 1 8 is covered by a thin mudguard.
  • the auxiliary stacking platform 9 is then moved back out of the stacking area and in the process transfers the partial stack formed on it to the pallet 3 the valves 22 automatically. Until the next stack change, the sheets 1 are stacked directly on the pallet 3.
  • auxiliary stacking platform 9 from individual slats 1 8 ensures great stability with a relatively low weight even with large working widths, eg. B. more than 2000 mm. There is no deflection due to the dead weight of the auxiliary stacking platform 9, so that the gap between the trailing edge of the sheet required for retraction can be kept very small. There are bigger gaps
  • auxiliary stacking platform 9 Disadvantage that the stack part located above the auxiliary stacking platform 9 is displaced somewhat when transferred to the pallet 3. Furthermore, the modular construction of the auxiliary stacking platform 9 made of lamellas 1 8 enables a structurally simple adaptation to different stack lengths.
