Definitions

  • the invention relates to a stack of bags, consisting of rectangular film sections made of thermoplastic plastic, which are folded around themselves at their bottom folding edges, with side weld seams and on their opening sides with central grip holes and lateral corner pieces delimited by perforation lines, which have aligned stack holes.
  • DE-GMS 74 29 628 discloses a stack of bags of this type, in which, in order to save material, the usual hanging strips, which extend over the width of the bag and are provided with hanging holes and from which the bags are torn along a perforation line, have been dispensed with.
  • the object of the invention is to create a stack of bags of the type specified at the outset, which enables further material savings with easier handling.
  • this object is achieved in a bag stack of the generic type in that only the rear wall of each bag is provided with perforation lines delimiting its two upper corner areas and in that the bag front wall has cutouts in its corner areas which are approximately congruent with the corner areas of the rear wall.
  • the stack of bags according to the invention enables a material saving of 50% compared to the known stack of bags, because only the rear walls of the bags are provided with corner areas serving for stacking and holding.
  • the individual pouch can be more easily torn off the stack of pouches because only one perforation line covering a wall has to be severed for this purpose.
  • the perforation lines are expediently curved, preferably quarter-circular, with parts approximately perpendicular to the opening and side edges.
  • the perforation lines have webs of different lengths, the web lengths being adapted to the course of force when the bags are torn off along the perforation lines and the possible curve shape of the perforation lines in such a way that tearing along the perforation line is ensured.
  • This configuration is particularly advantageous and expedient for reasons of simple and economical production of the bags according to the invention.
  • the bags according to the invention are expediently produced starting from a flat plastic film web, the side parts of which are folded over onto the middle part in such a way that their side edges lie at a close distance from their center line.
  • the tucked-in side parts of the plastic film web are weakened by semicircular punched-outs, so that further weakening of the middle part should also be avoided. Since the perforation lines have to be made in the middle part, the weakening cannot be completely dispensed with.
  • the web lengths of the punched perforation lines are designed in such a way that weakening of the web is avoided as far as possible on the one hand, but on the other hand non-destructive tearing of the bags from the bag block is ensured.
  • the perforation lines can be arranged such that they have long material webs in the areas of the opening edge and the side edge of the bag and shorter material webs between them. This arrangement of the shorter and longer webs of material takes into account the tensile and shear stresses occurring in the web, so that the web is not subject to any noteworthy expansions in spite of the punched-in perforation lines.
  • the material webs expediently decrease in length from the long to the short, so that good tearing of the bags from the stack is ensured after the tearing at the side edges.
  • the film tends to tear in a straight line. If the tear-off perforation line has a curved shape, shorter webs ensuring better tear-off should be provided, in particular in the area of curvature.
  • each bag expediently ends in front of the upper edge of the rear wall, so that the latter has an overlap-free strip.
  • Such an embodiment of stacked bags is known per se from DE-OS 24 08 831.
  • the bags are blocked together in the stack in the region of the perforated corners. are.
  • the blocking can also take place in the area of the stacking or hanging holes.
  • a method for producing the bags according to the invention is characterized in that the side parts of a plastic film web are folded over onto the middle part of the film in such a way that their side edges lie close together in front of their center line, so that the plastic film web folded in this way is intermittently one punched and one bag wide Welding stations are promoted in which the corner areas of the later rear walls of four bags lying side by side and in pairs in mirror image to each other are provided with a closed line with the perforation lines and with the stack holes, followed by the corner punching cutouts of the later bag front walls, then the finger hole punching and the bag side seams Cross-weld separating seams or cross-weld seams in pairs with cross-cuts lying between them and finally the bags still connected in pairs by along the middle cuts made on the plastic film web are never separated and stacked.
  • the cuts forming the tear-off perforation lines and corner punch cut-outs can be made by circumferential circular or elliptical cuts. However, the cut forming the corner punch cutouts is interrupted by the gap existing between the inward-tipped side edges of the web.
  • the tear-off perforation lines are rectilinear in their end regions and are approximately at right angles on the side and opening edges.
  • the circumferential cutting lines or tear-off perforation lines are designed as square cutting lines with rounded corners or polygonal cutting lines such that the perforation lines entering the side and opening edges are approximately at right angles to these.
  • the stack of bags 1 consists of stacked bags 2 which have been formed from rectangular plastic film sections by folding around the bottom fold line 3 on themselves.
  • the opening edges 4 of the front walls end at a distance from the opening edges 5 of the rear walls of the bags 2, so that overlapping strips 6 of the rear wall are formed on the opening side.
  • the bags 2 are provided in the middle with grip hole punchings 7 in the usual way.
  • the front walls of the bags 2 are provided with approximately quarter-circular punched-outs which are delimited by the cutting edges 8.
  • the back walls are approximately congruent with these cut edges with quarter-circle perforation lines 9.
  • the corner regions 10 of the rear walls, delimited by the perforation lines 9, are provided with punched holes 11 which are used for stacking and / or hanging the stacked bags 2.
  • the perforation lines 9 approximately perpendicular in the upper opening edges and in the lateral Shrink edges.
  • the perforation lines 9 have longer material webs 1 2, 13 in the area of the opening edges 5 and in the area of the sides.
  • the material webs 12, 13 are represented by solid lines. An area with shorter material webs is provided between the longer material webs 12, 13.
  • cut edges 8 and the perforation lines 9 are arranged approximately congruently. In the drawing they are shown offset from one another for the sake of clarity.
  • the individual bags 2 are provided in the usual way with side welds.
  • the side parts 15, 16 of a plastic film web are knocked onto the middle part 17 around the folded edges 3, in such a way that the inner side edges 18, 19 lie at a distance from the center line 20.
  • the double-folded web 21 prepared in this way is then conveyed by a conveyor in a known manner intermittently by steps corresponding to a bag width through the punching station 22, in which the corner configurations of the later bags are punched.
  • the punching device consists of a knife plate 23 which is fixed to the frame and which is provided with four punching tools 24 with an annular cutting edge for punching the stacking or holding holes 11 and with perforation knives 25 enclosing them in a circular manner is provided, which serve to punch the perforation lines 9.
  • the abutment plate 26 is lowered onto the corresponding central part 17 of the plastic film web 21.
  • the abutment plate 26 is attached to its actuation on the piston rod 28 of the cylinder 29 fixed to the frame.
  • the upper side of the abutment plate 26 serves as an abutment for the likewise circularly arranged knives 30 which are arranged on the knife plate 31.
  • the knife plate 31 is actuated by the piston rods 32, 33 of cylinders 34, 35, which are fastened to a holding plate 36, which in turn are fastened on the piston rod 28 of the cylinder 29.
  • the gap formed between the side edges 18, 19 of the film web 21 is so wide; that it is able to accommodate the piston rod 28, so that the abutment plate 26 can be inserted between the middle part 17 and the turned-in side parts 15, 16 of the film web 21.
  • the cylinders 29, 34, 35 are provided in a manner not shown with supply hoses through which a pressure medium, for example oil or compressed air, is supplied.
  • a pressure medium for example oil or compressed air
  • the ring-shaped knife 30 arranged on the underside of the knife plate 31 punches the corner cutouts 8 into the later corner areas of the folded-in web parts.
  • the width of the cutters 25 which cut the perforations 9 is such that the perforation cut has long web parts 12 in the transverse direction of the web and short web parts 13 in the longitudinal direction of the web.
  • the individual bags are later welded off from the web 21 provided with the corresponding corner configurations along the dashed cross lines 40 by cross-weld separating seams.
  • the double bags connected in this way in the area of the center line are later separated from one another by longitudinal cuts.
  • the finger hole punchings 7 can be punched with the cross weld separating seams or else separately.
  • Fig. 5 shows a plan view of a plastic film sheet 41, which is provided in the corner areas of the still connected bags with a square circumferential perforation punch cut 42 and an approximately congruent cut along a cutting line 43, which in the area of the longitudinal center line 20 of the film web through the between the inner edges 44, 45 of the formed web parts gap is interrupted.
  • the square perforation cuts and cutouts have rounded corners such that they open at right angles in the manner shown in the later opening edges and side edges of the bags.
