Definitions

  • the invention relates to a method and a device for stacking flat or flat material into packages, such as cubic stacks. their Stacked layers form flat surfaces and on all sides in the stack connect horizontally, in an inclined direction or vertically.
  • Stacks of material layers of different sizes can be provided, for example as a larger layer, a base layer, like a pallet, and as a smaller one Layers of individual sheet layers of paper or the like. The latter are in each case several stacked together with a covering or the like. and form a stacked layer, like a paper giant. All edge surfaces of the respective stacking layer are opposite to all associated and to it parallel edge surfaces of the base layer in the stack, so that they pass through the protruding base course - in the following called range - against shock loads are protected during transport.
  • the mutual precise alignment of the material layers, namely the pallet and the stacked layers - hereinafter referred to as the giant - is difficult when they are at merged at high speed and then as composite units should be transported away.
  • US 4,477,218 shows an offset stacker with the odd-numbered stack layers are laterally offset compared to even-numbered stack layers, so that these afterwards can be separated more easily.
  • a support plate for the recording the stack belongs to the device and is not together with the stack removable. For the different stack layers there will also be different ones Sliders and stops used.
  • DE-A 30 33 793 A shows a stop in a stacking device, which with the leading edge surface of a approaching partial stack and then with the opposite Stop surface is placed on the trailing edge surface of the partial stack, which is already on the stack stop.
  • US 4 927 321 shows a stacking device in which the stacking layers according to when they are placed on the stack, they can no longer be moved. lateral Stops only form an adjustable stacking shaft boundary.
  • the invention has for its object to a method and a device create the disadvantages of known training or described type can be avoided and in particular an accurate Alignment of the material layers after placing them on a table surface or on the stack or the like. Guaranteed, preferably a fully automatic Summary or stacking of the material layers should be possible.
  • Means are provided for the stacking layers, pallets and / or giant first put down on a table surface and one after each predetermined number of layers of material parallel to the table surface align.
  • the number mentioned can be between one and three or five.
  • the alignment is advantageously carried out in a first and a right-angled one second direction parallel to the table surface. With rectangular boundaries Material layers lie at right angles across and parallel to each of the directions Edge surfaces of these layers of material.
  • the funds first address the Sliding pallet on the table surface. After that, several giants are on the Pallet and placed on top of each other and then together on the pallet as well aligned with each other. Then all related to each other Edge surfaces of this giant are level and opposite to the associated ones Edge areas of the pallet set back with equal distances.
  • the same stops or sliders can both be used to align the pallet and subsequently used to align the giant.
  • a separate stop such as an overrun stop, is advantageous or a separate slide, such as a conveyor, is provided. He promotes the Giant from an area away from the stacking zone across the stack in doing so, and then hands them over to the Table.
  • the alignment stops can be used like pliers against each other and against the edge surfaces of the material layers are moved, in particular linear and parallel to the table level.
  • One of the two stops can be in its Stop position itself to be positively determined by stop to short positioning time to ensure accurate positioning.
  • the stacking table is useful as Height-adjustable lifting table, namely especially during stacking of the stack can be lowered by the thickness of each stack layer or stack layer. So the same transfer ratios for each stack layer to be deposited reached.
  • the stops could be stored on and against the stacking table across the table level, namely height adjustable. They are useful Stops in stationary mounts or bearings of the stationary Base frame of the facility secured. So changes with the height adjustment of the stacking table also their distance from the table level. The attacks can therefore always be in the area of the top layers of material and effective be while they are the underlying, already aligned layers of material can no longer touch.
  • the pallet is advantageous to the stacking table in one direction, for example the mentioned second direction, fed while the giant in a transverse to it or at right angles, for example the first mentioned Direction.
  • the stacking takes place at the stationary intersection and alignment of all material layers instead. Then the stack is rectified conveyed away to feed the pallet.
  • each of the material layers can be according to the EP 0 852 989 A3
