Definitions

  • the invention relates to a method for the production of at least one stack formed from bags, a stack formed from bags, a bag and a dispenser box according to the features of the respective preamble of the independent claims. It is known to make bags, especially plastic bags (such as trash bags, freezer bags or the like), and to co-wind them on a roll. A predetermined number of such bags is then on a roll. A user then sequentially separates the bags as needed to be fed to their intended use. This separation takes place, for example, in that the bags previously connected to one another via a perforation or welding are torn off by the user along this perforation.
  • plastic bags such as trash bags, freezer bags or the like
  • a dispenser for plastic film bag of the role which consists of a, preferably provided on both sides with foldings tubular film, which transverse Abr utilizatperforationen with at least a part average and in the vicinity thereof, in the drawing direction in front of these, also transverse welded bag bottom seams, wherein the dispenser has the shape of an approximately cylindrical sleeve having a longitudinally extending withdrawal slot for the tubular film, wherein at the overflowed from the tubular film in its withdrawal from the sleeve edge of the Abzugseschiitzes in the area each partial average in the tear-off perforation of the tubular film a projecting over this edge in the circumferential direction of the sleeve, that is projecting into the withdrawal slot or this almost completely bridging in its basic form is provided approximately rectangular tongue whose width in the longitudinal direction of the sleeve is equal to or only slightly smaller than the width of the associated part-average in the Abr employedperforation the tubular film
  • a method for producing at least one stack which is formed from bags, with the following steps: a) feeding tubular or semi-tubular material to form a lower material layer and an upper material layer, b) introducing at least one weld joint for connecting the lower layer of material and the upper layer of material to form individual, but still connected bags, c) introducing a formatting fold into the layer web formed from still connected bags, d) separating the bags associated in the formatted ply sheet into individual bags, these bags further having the formatting fold, e) forming a stack of individual bags, f) introducing at least one fold into the stack.
  • the method described above enables the continuous production of individual bags for the formation of at least one folded stack, which has an angular-shaped geometry (for example cuboid shape).
  • These stacks are suitable for inclusion in a container, for example a dispenser box.
  • the container likewise has an angular-shaped geometry which, in the inner region, corresponds approximately to the geometry of the at least one stack to be accommodated there.
  • the user can remove each bag individually from the stack with little effort. Also, the bags can not be damaged in the separation by the user or even destroyed. Each bag is made available to the user in consistent quality.
  • the package formation that is, the collection of individual bags to the total package or stack, respectively for a variable, but defined number of bags.
  • the layer web is formed from at least two layers of material.
  • the process can be carried out continuously if, for example, continuous, semi-tubular or tubular material is continuously produced by extrusion.
  • the process can be carried out batchwise or discontinuously if the web, semi-tubular or tubular material, for example, is available on rolls. It is also conceivable to connect the materials fed onto rolls before the consumption of one roll with the material of the next roll in order to obtain a quasi-continuous process.
  • Batch processes are processes that are processed as 'stack 1' , ie strictly one after the other, which is why batch processes are also referred to as batch processing
  • the batch process or batch process is a discontinuous production process in which a limited amount of material, for example a roll, is fed into the process as a whole and removed as a whole after completion of the production process, in this process for example as a stack consisting of Bags are formed.
  • a fold can be executed hard in the sense of a fold or with a rounding. Any folding of a fold between these extremes is also feasible.
  • a convolution is generated in the process by means which cause the direction reversal of the material. At least one fold, for example, to form a material tube or half-tube material can also be introduced into the material upstream of the process.
  • semi-tubular material material As a semi-tubular material material is referred to, which has undergone a reversal of direction for the formation of a lower and an upper material layer. This reversal of direction can also be understood as folding.
  • Semi-tubular material can be fed to the process or generated in situ from sheet material in the process. Also, semi-tubular material may be formed by forming a bonded seam in the longitudinal direction from two layers of web-like material prior to feeding to the process of the invention or while performing the inventive method are generated. The cohesive seam is produced for example by gluing or welding.
  • Tubular material is material which is self-contained, for example, made by extrusion or has a longitudinal connection point. This connection point can be cohesively, for example by gluing or welding, executed. If tubular material is exposed to pressure between two flat surfaces, a lower material layer and an upper material layer are formed. Each in the transition area between these two material layers, the material undergoes a reversal of direction which can also be considered as folding.
  • the invention provides that the stack is provided with a fuse to prevent the unwanted falling apart of the stack.
  • This backup can be done for example by a flexible, flexible element such as a wire, a belt or the like. Also, the backup can be done by surrounding the stack with shrink film. Alternatively, the backup by wrapping the stack with paper, for example, carried out as a band, done. Also, safety measures such as weighting the stack with a larger mass are covered by the idea of the fuse.
  • To secure the individual bags of a stack can also be provided with splices to attach the individual bags of the stack together, this backup should be designed to use the individual bags easily surmountable.
  • the fuse can also secure the transport of the stacks, for example, from the production of the stacks for packaging the stacks.
  • the provided with a backup stacks can be stored to later receive an outer packaging or to leave without further packaging measures the storage location.
  • the stack provided with the backup described above can be supplied to the storage or the transport and the sale, where it is alternatively also conceivable to supply the thus provided with the backup stack the container.
  • the fuse if necessary, must be removed if individual bags from the container and thus the stack to be removed.
  • the invention provides that the stack is transferred into a dispenser box.
  • the above method allows the continuous production of individual bags and the collection of bags to form a stack for inclusion in a dispenser box. Due to the formatting folding of the individual bags and the subsequent folding, for example carried out as Z-folding or U-folding, to form the stacks, it is possible to remove each individual bag from the dispensing opening of the dispenser box. The user can remove each bag individually from the dispenser box with little effort. Also, the bags can not be damaged in the separation by the user or even destroyed. Each bag is made available to the user in consistent quality. By combining the formatting fold with a further fold, for example the Z or U fold, it is advantageously ensured that after removal of a pouch, a further pouch is always provided for removal.
  • the provided with a backup stack can be transferred to a dispenser box. This facilitates handling of the stacks and prevents the stacks from falling apart before entering the dispenser box.
  • the backup can then be removed immediately after the stacks have been transferred to the dispenser box or removed by the user the first time they access the contents of the dispenser box. This ensures that the stacks do not change their shape during transport.
  • the invention provides that by means of markings, the weld is executed Rapportgenau.
  • the user thus receives bags of the same volume.
  • the markings for example a mark or several markings per bag, can also serve the user to achieve always the same fill levels in the bags. If the material supplied to the process has regular imprints, it is ensured that each bag is provided with the appropriate imprint.
  • the invention provides that the at least one folding introduced into the stack is carried out as a Z-fold, a W-fold, a concertina-type fold or a U-fold.
  • the at least one fold of the stacks already having a formatting fold per bag is characterized by a change of direction of the entire bag forming the stack.
  • a U-fold results in such a change of direction and a Z-fold in two such changes of direction.
  • There are also more than two changes of direction (convolutions) conceivable, for example, a W-folding or a concertina-shaped sequence of convolutions.
  • This makes it possible to adapt the stack individually to the format of the dispenser box and thus to increase the packing density.
  • a dispenser box can accommodate one or more stacks so folded. These stacks may, for example, be aligned parallel to one another, transversely to one another or else alternately parallel and transversely to one another. The formation of different angles between the individual Stapein is conceivable.
  • the invention provides that the formatting fold is introduced into the layer web in such a way that the width of the layer web after the introduction of the formatting fold corresponds at least to the inner dimension of an edge length of the dispenser box.
