Definitions

  • the invention relates to a method for producing stacks of sacks, each with bottoms closed at one end by a cross-weld seam, in which the front end of a tubular film web made of thermoplastic plastic and provided at the end with a cross-weld seam moves over the support carrying the stack at a distance of the sack length chlauchfolienbahn separated by a transverse separating cut of the S, and the new end of the tubular film web formed by the cutting edge is closed by a transverse weld seam and in which the following, formed in the same manner by transverse welds and transverse separating cuts bags successively to desired to Stack height are stored and the stored bags are each held on their superimposed open sides, and a device for performing this method.
  • this object is achieved in that the individual sacks placed one after the other in a region lying between their ends, starting with the first sack be pulled into interlocking loops with decreasing loop depth from sack to sack.
  • stack can be produced in which the uersch spanähten with the Q provided edge portions of the sacks offset imbricated manner one above the other, so that the weld areas not touch each other and can not stick together.
  • 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 so deep in the finished stack that all the loops lie inside 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 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 which are arranged laterally next to the stack and can be rotated intermittently by angular increments about a horizontal axis with a spiral cam curve.
  • a rotation of the cam curve corresponds to a stack formation.
  • rollers 2, 3 are with. Provide circumferential grooves, the bottom of which is indicated by the dashed line 4 and which engage in the comb-like blow air pipes 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 forward by the preferred pair of rollers 2, 3 from the balsa air stream in an elongated form 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 sacks 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 are two at a distance Assigned rollers one behind the other, of which the roller 18 simultaneously represents a roller of a conveyor belt 19.
  • a drawing rod 20 can be moved into the gap formed by the rollers 17 and 18 and is guided at both ends by a piston-cylinder unit.
  • the length of the drawing rod is dimensioned such that it exceeds the maximum bag width by so much that both the two piston-cylinder units 21 and two cam disks 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-duty 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 grows. In this way it is achieved that the individual bags or the bottom seams of the individual bags are shingled 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 are displaceable 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 becomes after the last one has been applied
  • the sack of a stack to be formed is moved all the way down. The prerequisite for this is that the highest point of the cam disc 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.
