Definitions

  • the invention relates to a bag made of a plastic film, in particular machine bag, with a filling opening, a front wall, a rear wall and in the region of the filling opening, extended rear wall to form a bag flap, wherein the front wall and the rear wall on their longitudinal sides, for the formation of side walls and at one of the filling opening opposite transverse side, to form a bottom seam, are welded together.
  • a collecting device for example, is a pen stack conveyor with a moving in the horizontal direction pen stack conveyor chain, which donate to stack receives the separated bag.
  • the stacking openings are punched, the distance of which correspond to the distances of the stacking pins on the pin stack conveyor chain.
  • a wire bracket wicket
  • either the bag stack is lifted from the stack pins of the pin stack conveyor and attached with the now loosely lying bags on the legs of the wire hanger or the legs of the wire hanger are inserted into hollow groove-like recesses of the stacking pins of the pin stack conveyor chain and removed in this way the respective bag stack ,
  • the respective bag stack To stabilize the stack of bags and to protect against damage by the ends of the wire hanger in the common packaging several bags stack these are inserted between a front and back cover sheet and additionally secured by plugged onto the legs of the wire hanger locking washers or rubber stoppers. All these operations are in the Usually performed manually by an operator and are in the EP 1 036 741 B1 described.
  • the torn edge region of the flap not only gives the bag an unattractive appearance, but it also adds that the bag flap surface is no longer readily for secure attachment of closure elements such as adhesive labels or the like and / or as a surface for printing or for receiving hints suitable is.
  • the wire hanger must be transported back to the manufacturer of the bag, sorted by size and optionally processed so that they can be used again.
  • the Antenau is formed as Abr employperforation of each one extending at an angle to the filling opening, a corner portion delimiting perforation lines, and arranged in each corner portion at least one bag stacking together in the stack Verblockungsstelle.
  • the disadvantage of this is that the bag stack continues to be inserted in their limited number by hand and the perforated, blocked and remaining in the machine edge portion must be removed.
  • the invention has for its object to provide a bag stack of the type mentioned, which requires no expensive tools, beyond the performance of a packaging machine significantly increased and can be realized with minimal design and material expense.
  • the bag has an extension projecting beyond the bottom seam and that at least the bag flap is releasably connected to a bag flap of another bag and the extension is connected continuously and detachably to the bags. Due to the inventive design of the bag or rather the interconnected bag is now created the possibility of a machine bag as rolls, for example, in a packaging machine to insert.
  • the continuous, that is over all interconnected bags extending extension at the bottom of the bag in the bottom seam serves as a holding or winding strip.
  • the holding or winding strip is detachably connected to the bags, this can be done for example by means of a perforation, which is introduced into the bag together with the production of the weld of the bottom seam.
  • the holding or winding strip acts on the one hand as a link between the bags and on the other hand, a continuous plastic film strip for safe transport of the bags is provided in the packaging machine.
  • the holding or winding strip is separated from the bag and can be taken care of separately, the holding or winding strip is also rolled up again in the packaging machine is a lightweight and space-saving disposal allows.
  • the detachable connection in the region of the bag flap serves exactly as the extension in the region of the bottom seam as a holding or winding strip, wherein the bag flap is connected as a functional element of the bag fixed to the bag, wherein the bag flap is preferably formed as part of the rear wall of the bag ,
  • the juxtaposed bag flaps detachably connected together.
  • the bag flaps are connected by means of a perforation, so that an easy separation of the bags in the packaging machine can be realized.
  • the requirement is placed on the perforation that it is strong enough to allow it to be wrapped and transported through the machine and, on the other hand, the perforation must be easily detachable in order to enable a problem-free separation of the individual bags in the packaging machine.
  • wound bags in packaging machines significantly increases the number of bags available in the machine. If approximately 500 bags are present on a bag stack known from the prior art, it is possible to wind a multiple of bags onto a roll or into itself by winding the bags into a roll of bags depending on the size of the bag, the diameter of the roll and the thickness of the film , This in turn has the advantage that an operator of the machine must spend less time for the assembly of the packaging machine, which in turn has a positive effect on the non-productive time, in particular the loading times of the machine.
  • FIG. 1 a partially unwound bag roll 1 is shown in a three-dimensional view, it is possible to wrap the bag 2 in itself or to wind the bag 2 on a roll.
  • the bags 2 consist of a front wall 3 and a rear wall 4, which are connected in this embodiment with a bottom fold 5. It should be noted here that the bag 2 can of course also be formed without bottom fold 5.
  • the bags 2 are made of a plastic film, which is preferably a thermoplastic film, which has a thickness of 20 .mu.m to 100 .mu.m, preferably with a thickness of 35 .mu.m to 80 .mu.m.
  • a preferred plastic here is polyethylene (PE).
  • the bag 2 has a bag flap 9, which is formed from a part of the rear wall 4. By means of the bag flap 9, the bag 2 is closed after filling, such as in the DE 199 17 902 A1 described.
  • a further part of the rear wall 4 forms in this embodiment, the extension 10.
  • the extension 10 is continuously connected to all bags 2, wherein the extension 10 releasably, preferably by a perforation 11, is connected to the bag.
  • the bags 2 themselves are separated by means of a Trennnahtsch practiceung 12 or a double Schrumpfnahtsch professionung 12 from each other, which at the same time the side seams 13, 14 are generated by this weld.
  • the bags 2 are connected by means of a further perforation 15. If the bag flap 9 is not needed in a machine bag 2, a perforation 16 can optionally be attached to the bag opening 8 so that the bag flap 9 can be separated from the bag 2.
  • the bags 2 from a half-tube, wherein during the folding of the bottom fold 5 from the half-tube simultaneously form the front wall 3 and the rear wall 4.
  • the bottom fold 5 is inserted into the half-tube such that an extension 10 and a bag flap 9 in the, as in FIG. 1 shown form present.
  • the extension 10 would be double-walled.
  • To form a bag 2 then only a weld 7 in the region of the bottom of the bag 2 would be necessary.
  • the finished bags 2 in the filling area 8 and in the region of the bottom of the bag are provided with carrier films 9, 10, preferably of the same material.
  • the carrier films 9, 10 are torn off by a perforation 11, 16 or cut off by means of a cut and thus separated from the bag 2. It is therefore even possible according to the invention to dispense with a perforation 11 in the region of the bag bottom 17 and to introduce only a perforation 15 between the bag flaps.
  • the bags 2 can be rolled up and create larger containers 1.
  • the carrier films are 9, 10 separated from the bag 2 and disposed of, the separated carrier films 9, 10 can be recycled by recycling.
  • FIG. 2 shows the in FIG. 1 bag 2 described in detail in a fold, in which the bag flap 9 and a part of the front wall 3 has been folded over the filling opening 8.
  • FIG. 2 shows the left side in the FIG. 2 and on the bottom of the bag 17 in the area of the bottom fold 5 each have a 4-layer structure, whereby a uniform winding and thus a uniform thickness bag roll 1 is made possible.
