Definitions

  • the invention relates to a method for separating a packaging bag segments containing a plurality of product stacks, in particular of hygiene products, comprising film bag segments which are in each case containing one or two product stacks. It further relates to a packaging installation for packaging products in packaging bags, in particular for carrying out the method, and to a perforated tubular film for use in such a method.
  • Hygiene products such as paper handkerchiefs, panty liners, sanitary napkins, diapers or the like are usually packaged individually or in predetermined batches, for example in the form of five or ten packs, in film and offered ready for consumption or ready for use in this packaged form.
  • the film surrounding the hygiene product or the stack of hygiene products forms a so-called packaging bag, which i.a.
  • packaging bag which i.a.
  • it can be equipped with a perforation for easier opening and / or with adhesive tabs or the like for resealing.
  • other products or product batches such as cigarette packs or the like, can be provided with such a packaging bag in the manner of an overpack.
  • the product in particular the hygiene product or the stack of hygiene products
  • it may be provided, for example, that suitably cut film pieces intended to form the packaging bag are provided in which the product is inserted, the film subsequently being wrapped around it and welded at the edges.
  • a packaging bag for example, from DE 101 48 283 A1 in which a so-called cellular wheel is provided for the actual packaging step.
  • the intended for forming the packaging bag film is first inserted into a chamber of the cell wheel, then a stack of hygiene products is also introduced into the chamber of the cell wheel. Thereafter, the side edges of the film are circumferentially overlapped around the stack of sanitary products and appropriately welded together.
  • a so-called film tube packer can be used, as he, for example, from the DE 10 2008 020 800 A1 is known.
  • the sanitary products or packages of hygiene products to be packaged are positioned in a so-called tubular bag machine in a film tube, which is then welded together and separated between the products.
  • the packaging systems are usually designed in the manner of continuous systems.
  • the products to be packaged are conveyed consecutively, individually or in stacks along a transport direction and surrounded with the packaging bag during the passage through various system components arranged along the transport direction.
  • the above-mentioned film tube systems are generally well suited for high processing speeds and throughput rates, since, for example, during the wrapping of the products or product stack in the tubular film to form the film tube welding of the lateral longitudinal seam from the side, ie in the run and without system standstill, is possible.
  • a film tube packer is known, are packed with the paper rolls in a film tube.
  • lines of weakness are formed transversely to the continuously moving path.
  • the paper rolls are introduced and wrapped with the film.
  • the continued moving at a continuous predetermined speed on a conveyor belt packages are transferred to another conveyor at a higher speed.
  • the film tube is partially severed at its line of weakness by primary crusher, so as to ensure that the tension under tension film tube is not falsely also tearing at other locations.
  • primary crusher which strikes the tensioned film in a predetermined cycle, there is a risk, particularly for packages with opening perforation for easier opening of the packaging, that it tears at undesired locations.
  • the invention is therefore based on the object of specifying a method for separating a film tube containing a plurality of product stacks into packaging bag segments each containing one or two product stacks, with which particularly high throughput and production rates can be achieved. Furthermore, a packaging system which is particularly suitable for carrying out the method and a perforated tubular film which is particularly suitable for use in the method should be specified.
  • this object is achieved according to the invention by providing the tubular film intended for forming the film tube at the intended separation points with a perforation such that the perforation associates a number of opening perforations respectively each opening perforation, each with a substantially rectilinear separation perforation comprising in its central region in a corresponding to the width of the respective opening perforation length a continuous relief section, the product stacks are then wrapped in the tubular film, containing the product stack containing film tube under frictional lateral access in a conveyor system, with a constant first transport speed, to a Separating unit is transported, in which seen in the conveying direction front packaging bag to another conveyor system with respect to he At least temporarily increased conveyor speed is transferred to the conveyor system and thereby the film tube formed is torn apart at the respectively provided separation point, wherein the transport speed of the further conveyor system is impulsively and temporarily increased upon arrival of the front seen in the conveying direction packaging bag.
  • the invention is based on the consideration that in order to achieve particularly high throughput and production rates a continuous and uninterrupted passage of the products or product stack through the packaging system should be sought. In order to prevent system downtimes or even short-term interruptions in the further transport of the products or product stacks as far as possible, all processing steps during the introduction of the products or product stacks into the respective packaging bags should be designed consistently for a continuous operation.
  • the use of cutting means requires that positioning of the cutting means relative to the film tube initially be carried out to perform the cut, so that the separation also takes place at the desired separation point.
  • This positioning, including the subsequent actual cutting process usually requires - on its own Precision reasons - a temporary system downtime that is detrimental to the desired high processing speed.
  • separation should therefore be based on a different concept in principle.
  • the separation of the packaging bag segments should be carried out by tearing the film tube at predetermined separation points.
  • the pre-processing for perforation of the tubular film takes place with the aid of a perforation device provided for this purpose.
  • the pulled down from a supply roll tubular film is thereby perforated, from one side edge of the tubular film to the other side edge, across the entire film web with a continuous perforation. It can be adjusted by a control of the distance between the individual perforations to each other, so that depending on the packaged hygiene product different packaging lengths.
  • the film tube thus always envelops the products to be packaged with a necessary film projection.
  • the supply of the provided with the product stacks film tube is provided in a separation unit.
  • the longitudinal direction of the film tube suitably selected longitudinal forces are applied, which cause a rupture of the film tube to the separation points defined by the perforation.
  • a mechanical, frictional access to the film tube is provided in an advantageous embodiment.
  • This can be done, for example, by conveying the product stack containing film tube in a conveyor system, attack in the conveyor belts with suitably selected, for example, rubberized surface laterally on the film tube.
  • the film tube is guided between a pair of such conveyor belts, so that they support each other and the film tube is guided clamped therebetween.
  • the film tube is expediently transported to a separation unit in which the seen in the conveying direction front packaging bag segment is passed to another conveyor system with compared to the first conveyor system at least temporarily increased transport speed. Due to the excess speed of the receiving conveyor system of the film tube thereby stretched in its longitudinal direction until it breaks at the weak point, namely the separation point provided by the perforation between two product stacks.
  • a particularly high level of reliability in the separation can be achieved by constructing the longitudinal forces required for the separation in the film tube in a particularly advantageous development, particularly in accordance with demand and preferably also synchronized with the working cycle of the corresponding packaging machine provided in any case.
  • the conveying system which takes over the respective packaging bag segment to be cut off or picked up is advantageously not operated with a constant transport speed but with a variably controlled transport speed.
  • the transport speed of the further conveyor system is particularly advantageous when the arrival in the conveying direction front packaging bag segment pulse-like and temporarily, preferably by about 20% - 35%, particularly preferably increased by about 25% - 30%.
  • the separation unit is advantageously designed as a transfer station for the incoming, under frictional lateral access in a conveyor system supplied film tube to another conveyor system compared to the first conveyor system at least temporarily increased transport speed.
  • the separation unit also comprises a control unit for adjusting the transport speed in the further conveyor system.
  • the control unit is expediently designed so that it needs, ie in synchronization with the system clock, the transport speed in the receiving conveyor system briefly and temporarily suitably increased upon arrival of each demolished packaging bag segment, so that jerky a corresponding longitudinal force is introduced into the film tube, the then leads to rupture at the predetermined by the perforation separation point.
  • the conveyor systems are each designed as a belt conveyor with laterally acting on the film tube or the packaging bag segments conveyor belts, the conveyor belts are guided in the region of the transfer station via pulleys.
  • the pulleys are in a particularly advantageous embodiment in their dimensions and / or with respect to the distance of their axes of rotation from each other, especially in the transport direction of the products, adapted to a perforation pattern in the film tube.
  • the design goal of a reliable rupture of the film tube to the designated, provided by the appropriate separation perforation separation points is thereby taken into account that on the one hand the resulting by the deflection of the conveyor belts in the transfer station gap between the access areas of the conveyor systems is sufficiently large, so that the separation perforation at the moment of rupture, so the pulse-like increase in the transport speed in the second conveyor system seen in the transport direction, safely between the access areas of the conveyor systems.
  • the gap between the access areas which is variable in particular by the combination of the diameter of the deflection rollers and the distance from their axes of rotation, should be sufficiently large.
  • this gap should also be sufficiently small, so that even at the moment of rupture sufficient access of the respective conveyor systems on the parts to be separated of the film tube, so both sides of the separation point a sufficiently long contact area of conveyor belt and film tube is given.
  • the last-mentioned aspect can be particularly significant if, in addition to the aforementioned separation perforation in the film tube, a so-called opening perforation is also provided.
  • a so-called opening perforation is also provided.
  • Such an opening perforation is used in particular if, in the finished packaged product, a facilitated opening of the packaging bag for access to the products contained therein is to be provided for the end user.
