Definitions

  • the invention relates to a device for stacking sheets, in particular sheets of paper or cardboard, on a pallet according to the preamble of patent claim 1.
  • Generic stacking devices are used in the processing of paper or cardboard to store sheets which, for. B. were produced with a cross cutting machine, continuously stacked on pallets. In order to keep the drop height of the sheets constant when laying them down, the pallets lie on a lifting and lowering storage platform that is continuously lowered in accordance with the height of the stack.
  • a generic stacking device in which the sheets are stacked during a pallet change on an auxiliary stacking platform that can be moved into the area of the storage platform in order to be able to carry out the stack change without loss, that is to say without removing sheets, at full working speed .
  • the storage platform can be lowered to remove the finished stack and pick up a new empty pallet.
  • the new pallet is then moved up with the storage platform to below the auxiliary stacking platform, and the intermediate stack is transferred to the new pallet by moving out the auxiliary stacking platform.
  • the invention has for its object to be able to determine the pallet height in a generic stacking device so that a problem-free transfer of the intermediate stack from the auxiliary stacking platform to the new pallet is possible.
  • the entire pallet surface is scanned when determining the pallet height.
  • the sensing element can depress depressing elevations, which are therefore not registered.
  • the feeler element is advantageously arranged fixed in the area of the pallet feed to the storage platform. The pallet height can thus be determined when a new pallet is transported to the storage platform.
  • Claim 4 contains an advantageous arrangement for measuring the vertical deflection of the probe element to determine the maximum deflection.
  • the adjustable contact pressure according to claim 5 enables the adjustment of the pallet height determination to disturbing and non-disturbing elevations.
  • the probe element is expediently connected to a double-acting piston-cylinder unit, so that the contact pressure can be increased or decreased.
  • Fig. 1 shows a stacking device according to the invention in side view transverse to the direction of the sheets.
  • FIG. 2 shows the device for determining the pallet height in an enlarged detail from FIG. 1.
  • the frame of the stacking device has four stands 1, 2, between which there is a lifting and lowering storage platform 3.
  • the depositing platform 3 can be raised up to the conveying plane 4 of the scalloped sheets 5 and lowered down to the floor, where it is aligned with an infeed conveyor 6 for empty pallets 7 which leads through the space between the stands 1.
  • the feed conveyor 6 as well as the top of the platform 3 funding, z. B. roles with which the pallets 7 can be transported for a pallet change in the running direction of the sheets 5.
  • auxiliary stacking platform 8 In the uprights 1 there is a lifting and lowering auxiliary stacking platform 8 which can be moved horizontally into the area of the storage platform 3 by means of a drive 9. The sheets 5 are stacked on the auxiliary stacking platform 8, while full stacks are removed and new pallets 7 are transported into the stacking area. When stacking on a pallet 7, which lies on the storage platform 3, the auxiliary stacking platform 8 is located outside the stacking area (on the left in FIG. 1). As far as the stacking device is known and z. B. described in DE-PS 37 39 194.
  • a device for determining the pallet height is arranged between the two upright stands 1 and is shown enlarged in FIG. 2.
  • two cross members 11, 12 are fastened at the same height over the working width.
  • Two lateral pivoting levers 13 pointing in the direction of sheet travel are articulated on the front crossmember 11, between the free ends of which a runner 14 extending over the working width is fastened.
  • the length of the pivot lever 13 and its position is chosen so that the runner 14 can be lowered to close to the floor (up to a distance of approximately 80 mm) and raised to a position above the maximum height of a pallet 7 and thus onto the surfaces the continuous pallets 7 can be placed.
  • the downward pressure in the piston-cylinder unit 15 can be adjusted by means of a fine control valve.
  • a side plate 16 on one side on the crossmember 12 with a vertical guide 17 for a vertical rack 18 connected to the runner 14 attached, which meshes with the pinion 19 of an angle encoder 20 attached to the side plate 16.
  • the angular encoder 20 thus registers the vertical deflection of the runner 14 when passing through a pallet 7.
  • the contact pressure which depends on the weight of the runner 14, is set by means of the piston-cylinder unit 15 in such a way that non-disturbing elevations, such as protective papers lying on top, which are folded up, are depressed and are therefore not registered.
  • Disturbing surveys such as protruding nails, on the other hand, lead to a deflection and are registered.
  • the stored maximum height h of the pallet 7 then serves to control the approach of the storage platform 3 with the pallet 7 lying on it from below to the auxiliary stacking platform 8. So that the supply of sheets 5 does not have to be interrupted when changing stacks, an intermediate stack 22 is formed on the auxiliary stack platform 8 until a full stack has been removed and a new pallet 7 has been moved under the auxiliary platform 8 carrying the intermediate stack 22. During the intermediate stacking, the auxiliary platform 8 moves continuously downward in order to keep the surface of the intermediate stack 22 approximately at the level of the feed plane 4. Since the intermediate stack 22 is placed on the advancing new pallet 7 by pulling out the auxiliary stack platform 8, it is It is necessary to position the new pallet 7 exactly below the auxiliary stacking platform 8 to a small safety distance (approx. 10 mm).
  • the movement of a new pallet 7 against the underside of the auxiliary stacking platform 8 is controlled in such a way that an inductive proximity switch 23 arranged on the underside of the supporting structure of the slide 8 registers the approach of the storage platform 3 as a reference point if the pallet 7 is still a sufficiently large distance from the auxiliary stacking platform 8 has.
  • This known distance is then further reduced by lowering the auxiliary stacking platform 8 and lifting the storage platform 3 until the distance of the surface of the storage platform 3 from the auxiliary stacking platform 8 is only the measured height of the pallet plus 10 mm safety distance.
  • These further approaches are controlled via two angle encoders, one of which measures the vertical movement of the auxiliary stacking platform 8, the other the vertical movement of the storage platform 3.
  • the feeler element (runner 14) is arranged horizontally in a stationary manner.
  • the palette is moved relative to the probe element to scan the entire pallet surface. It is also possible to arrange the probe element so that it can be moved horizontally, so that it can be moved over the entire surface of a stationary pallet. So z. B. a movable between the stands 1, 2 feel the palette 7 resting on the storage platform 3. Then it has to Push element can be moved from the storage area into a position not disturbing the stacking.
