Definitions

  • the invention relates to a system and a method for the production and subsequent palletizing of hose sections, bags or sacks according to the preambles of claims 1 and 20.
  • Hose sections, bags or Sacks are usually made of single or multi-layer material webs in it provided processing machines manufactured.
  • To the formation of Hose sections are used devices such as in the patent DE 36 40 219 C1 and in DE 44 40 660 C2 and shown to be discribed. From such tube sections then sacks, in the form of Kreuzêtventilsburgen be prepared.
  • Patent DE 195 49 618 C2 is shown as the ends of a Hose piece for producing such a cross bottom raised become.
  • the said tube sections, bags or sacks are usually for Stacked for purposes of their removal or storage.
  • Known systems For stacking the products they usually comprise a stacking device, such as it is disclosed for example in the patent DE 37 07 845 C2. These piles are then usually placed on pallets in order to simple Way to be transported away.
  • the stacks can also be before they are placed on storage elements and stored, still on or in Caching be stored. After stacking and eventual caching, the stacks are on storage elements arranged and filed.
  • the stacks of hose sections, bags or sacks can be in arrange and stack on a memory element if within each stack the edges of the superimposed ones Hose sections, bags or bags are exactly on top of each other.
  • Both known systems for manufacturing and palletizing exists in this Regard potential for improvement.
  • the stacks in the Usually stored by hand on the memory element. This procedure is slow and with great inaccuracies, very staff intensive and so expensive. Overall, arranging and saving the stacks after the State of the art very ineffective.

  • this object is achieved by the features of characterizing part of claim 1. Accordingly, this includes said system an alignment unit for the stack of tube sections or bags showing the mutual deviation of the edges of the Tube sections, bags or sacks reduced. In this alignment unit is So the shape of the stack of a cuboid shape better approximated. Compared A manual alignment can do this much more accurately and moreover done faster.

  • a Palletizing device In one of one Cuboid strongly divergent form of the stack would be the employment of such a Palletizing device not possible or there would be tube sections, bags or bags in the stack even damaged.
  • a Palletizer can due to the more precise storage of the stack on a memory element much more stacks are stored as in the case of manual filing. In case of too inaccurate arrangement of the stacks on the Storage element can slip and fall piles.
  • the alignment unit has over an alignment table, which is equipped with stops. On this Aligning the stack can be independent of the entire system be aligned. For example, the alignment table can be moved separately become. At such an alignment table two stops are provided. Runs the main axis of the aligned pieces of hose, bag or Bags across the transport direction, so a stop extends advantageously parallel to the main axis of the hose pieces, bags or Sacks, while the second stop is parallel to the transport direction. Both attacks thus form a right angle. In general, the However, attacks can be arranged on any two lines, both Stops can form any angle.
  • the alignment table has means for tilting the stack features.
  • These means for tilting can be, for example, conveyor belts that move the stack from a horizontal plane to an inclined plane.
  • the inclined plane is then also part of the alignment table, wherein this inclined plane will then be used to align the stack can.
  • the hose pieces, bags and sacks also act Gravity - based forces that contribute to the mutual displacement of the Hose pieces, bags and sacks can lead.
  • the means for tilting the stack a pivoting device, with which the alignment table so is pivotable that the stack is inclined against gravity. After Pivoting movement is inclined to the stack, so that gravity on the Hose sections, bags or sacks acts, so that their edges on the Create stops.
  • the pivot axis, around which the pivoting device pivots the swivel table an angle with both stops.
  • a pivoting movement of the table lie down the individual pieces of tubing, bags or bags each with an edge each stop, so after this donning the hose pieces, bags or bags take a well-defined position in the room.
  • These Alignment is especially effective when the pivot axis and each stop enclose an angle of about 45 degrees.
  • bags or sacks can also be another angle advantageous be.
  • the alignment unit must be fed with the stacks.
  • a first transport device provided, which conveying elements such as transport rollers or conveyor belts comprising the stacks in a direction of transport to the alignment table. and / or dissipates.

  • the first power transmission means can a disc that is pressed with spring force in the direction of the alignment table is to ensure optimum power transmission.
  • the others Power transmission means may be one or more shafts to which Conveyor belts or belts are clamped.
  • the alignment table with a vibration generating element equip.
  • generating vibrations of sufficient amplitude and suitable frequency can be the individual pieces of tubing, bags or temporarily remove sacks from each other so that the frictional force between them is lowered. An independent movement of the individual Hose pieces, bags or sacks are thus facilitated.
  • the stack can also be sufficient to convert the stack into a cuboid shape be to provide means for tilting the stack, which the alignment table already tilt in its rest position or hold in a tilted position, so that the stack is tilted when it is a position on the alignment table occupies.
  • the stack may in this embodiment of the invention For example, be transferred to a tilted alignment table, so that alignment takes place through the influence of gravity.

  • the vibration transmission element advantageously comprises a comb-shaped carrying table.
  • the Carrying table between the conveyor elements such as conveyor belts rest.
  • the support table may be so be raised, that the individual tines of the Trageticians between the Step up conveyor belts and then carry the stack alone.
  • the number The tines and thus the conveyor belts must be sized so that the Hose pieces, bags or sacks between the tines as little as possible bend.
  • the vibration mediation element bearing surfaces on which the stacks come to rest which is a lesser Have friction to the stacking material as the second transport device.
  • the Stiction between the bearing surfaces is determined by the size of the Pads determined as well as their coefficients of friction.
  • the Support surfaces can therefore be the side edges of flat trained Be supporting elements. To the lowest possible friction coefficient achieve, these support elements may be made of metal. Also one suitable coating of the support elements can be provided, in addition to Low friction also offer the advantage of high wear resistance can.
