Definitions

  • the invention relates to a method for producing stacks from bags according to the preamble of patent claim 1 and an apparatus for carrying out this method according to the preamble of patent claim 4.
  • the sacks are placed on a stacking belt which is inclined downward about a deflection roller in such a way that the end of the stack is fanned out with the bottom weld seams and the individual transverse weld seams are each offset by a small amount relative to each other. In many cases, however, this offset is not large enough to reliably prevent the floor weld seams from sticking or blocking together.
  • the object of the invention is therefore to provide a method according to the preamble of claim 1, according to which sacks or bags can be stacked up immediately after their production without fear of mutual sticking of the fresh weld seams to one another.
  • stacks can be produced in which the edge regions of the sacks provided with the transverse weld seams are offset one above the other in a scale-like manner, so that the weld seam regions cannot touch one another and cannot bond to one another.
  • the offset placement of the bags or sacks in the stack can be maintained if the finished stack is held and transported away in its front region behind the edge regions of the sacks, which are offset in a scale-like manner and provided with transverse weld seams.
  • the area lying in loops smoothes itself during transport or can be brushed out by rolling or the like.
  • the loop formed in the uppermost sack can be pulled deep enough in the finished stack that all the loops lie in one another and also touch one another in their apex region. This deep retraction of the loop of the top sack pulls the protruding front ends of the sacks into the stack.
  • the object of the invention is achieved in a device according to the preamble of claim 4 by the characterizing features of claim 4.
  • the gap is expediently formed by two rollers arranged parallel to one another.
  • the front roller in the feed direction can be formed by the rear deflection drum of a conveyor belt that conveys the stack.
  • the insertion element can consist of a rod, the ends of which are attached to the piston rods by piston-cylinder units arranged vertically to the side of the stack.
  • the lowering path of the rod is limited by cam disks with a spiral cam curve that are arranged laterally next to the stack and can be intermittently rotated by angular increments about a horizontal axis.
  • a rotation of the cam curve corresponds to a stack formation.
  • rollers 2, 3 are provided for the intermittent preference of the plastic tubular film web 1, which can also be provided with side gussets in the case of the production of gusseted bags or bags.
  • the rollers 2, 3 are provided with circumferential grooves, the bottom of which is indicated by the dashed line 4 and which engage in blown air tubes 5, 6 arranged in rows.
  • the tubular film web 1 is passed between the blown air tubes 5 and 6, so that the front end of the tubular web pulled by the preferred pair of rollers 2, 3 is stretched by the blown air stream between the opened welding jaws 7 and 8 and the upper and lower knives 9, 10 of the cutting tool is carried through a bag length after the front edge of the tubular film has been closed with a weld seam.
  • a hold-down device 11 and an abutment 12 assigned to the hold-down device are arranged downstream of the upper and lower knife 9, 10, the hold-down device 11 consisting of an angle iron which can be actuated by a piston-cylinder unit 13.
  • This angle iron is provided with recesses, not shown, so that the hold-down device passes through the rows of needles 14 of a needle bar 15 during its downward movement and thereby pushes the heavy-duty bags with their opening edge onto the needles 14.
  • the abutment 12 limits the path of the hold-down 11, which, as already mentioned, can be moved up and down by the pneumatic piston-cylinder unit 13.
  • both the abutment 12 and the needle bar 15 are lowered via a piston-cylinder unit 16.
  • the needle bar 15 is assigned two rollers which are provided at a distance one behind the other, of which the roller 1 simultaneously represents a roller of a conveyor belt 19.
  • a drawing rod 20 can be inserted, which is guided at both ends by a piston-cylinder unit.
  • the length of the drawing rod is dimensioned so that it exceeds the maximum sack width by so much that both the piston-cylinder-in units 21 as well as two cams 22 can attack at their ends.
  • the drawing rod 20 is moved from its upper position, not shown, in which it does not hinder the discharge of individual heavy goods bags, into the lower position shown in the figure, so that a loop is formed.
  • the cams rotate clockwise by a certain amount, so that the depth of the loops in the individual heavy-duty sacks becomes smaller as the stack increases. In this way it is achieved that the individual sacks or the bottom seams of the individual sacks lie in shingled relationship to one another and therefore cannot stick to one another.
  • the clamping jaw 23 is then lowered onto the stack by two piston-cylinder units 24 which engage it laterally, so that the latter is pressed onto the conveyor belt 19.
  • the piston-cylinder units 24 are fastened to racks 25 which are guided in rails in a manner not shown and can be displaced via pinions 26.
  • the pinions 26 are connected to the drive of the conveyor belt 19, so that the stack can be removed by the conveyor belt 19. In this case, a stack is obtained in which the weld seams are shingled next to each other.
  • the drawing rod 20 is moved all the way down after the application of the last sack of a stack to be formed.
  • the prerequisite for this is that the highest point of the cam disk 22 is turned out of the area of the drawing rod 20.
  • cam disc 22 rotates through 360 ° during the formation of a sack stack.
