Definitions

  • the invention relates to a method and a device for producing a beverage container.
  • a beverage container in which these disadvantages do not occur has already been proposed in DE-OS 4240540.8.
  • the puncture hole 3 is punched through all layers of a mono- or composite material 1a, b, c of the front-side film 1.
  • a sealing film strip 2 is welded to the inside of the front film at a first welding point 4 around the puncture opening, so that a tight seal is produced.
  • the sealing strip is also held at a second welding point between the front and rear film on the side seams 5 of the beverage container.
  • the beverage container shown in FIG. 4 also has a base film part which is welded between the front and rear side films.
  • the present invention is therefore based on the object of providing a method and a device for carrying out the method, which allow a continuous, economical and reliable manufacture of such beverage containers.
  • this object is achieved by a method in which a puncture opening is produced in a front-side film web guided in the transport direction, whereupon a sealing film web is guided in the transport direction to the front-side film web, and then is welded around the puncture opening to the inside of the front-side film web and a back-side film web in the transport direction is fed in such a way that the inside of the front film sheet welded to the moving sealing film sheet faces the inside of the back film sheet, and then the front film sheet and the back film sheet are at least partially welded together along the side edges of the beverage container to be produced, including the sealing film sheet.
  • a device for carrying out the method which has the following: a conveying device for a front-side film web, a conveying device for a rear-side film web, a device for creating a puncture opening through the front-side film web, a conveying device for a sealing film web, a first sealing device around the Closure film web on the inside of the front film web to seal the puncture opening, and a second sealing device to seal the front film web and the back film web at least partially along the side edges of the beverage container to be produced, including the film web.
  • the concept according to the invention permits continuous production of the beverage containers, it being possible for a closure film web to be fed continuously intermittently.
  • the flowing production process is not specifically interrupted by the attachment of the sealing film, since the sealing film web is guided in the direction of transport and is welded to the front film web and carried along with it. It is also advantageous that the sealing film web is also held by welding the side edges of the beverage bag, so that no additional side welding of the sealing film web is required.
  • the sealing film web does not have to be aligned in the transport direction to the front film web, as is e.g. when applying already cut sealing film strips would be the case.
  • the fact that the front, back and also closure film web are guided separately from one another makes it possible for these films to be optimized separately from one another.
  • the rigidity and flexibility of each individual film can be optimally adjusted.
  • the technology according to the invention offers the advantage that, for example, printing on the backside film can be dispensed with, and thus a very cost-intensive operation is completely saved in the film production. The production is so precise that there is no need to trim the bags.
  • a bottom film web is guided in the transport direction between the front and rear film web and is partially welded to the front and rear film web in the bottom region of the beverage container to be produced.
  • a stand-up pouch can be produced, for example, by welding in a base part. Because the bottom film web is also guided in the transport direction, the flowing production process does not have to be interrupted are used to seal the bottom film sheet. Since the bottom foil is also guided separately from the other foils, the bottom foil can also be optimized independently of the other foils.
  • a certain number of beverage bags to be produced can be provided next to one another, in a direction perpendicular to the transport direction, on the front and back film webs, and this number of puncture openings corresponding to this number can be produced next to one another in the front film web, and a corresponding number of sealing film webs can be fed in and around the respective puncture openings are welded.
  • a large number of base film webs can also be fed in according to the number and welded between the front and rear film webs. This means that several bags can be produced in one machine cycle.
  • the foil webs welded together are then cut into individual beverage containers.
  • a device for carrying out the method advantageously, as already mentioned, has a further conveyor device for a bottom film web, which is arranged such that the bottom film web is transported in the conveying direction between the rear and front side film web, and further a third welding device for at least partially welding the front - And backside film web with the bottom film web in the bottom area of the beverage container to be produced.
  • a cross cutter can be provided for cutting the foil webs welded together into individual bags.
  • a certain number of beverage bags can be placed next to each other on the front and back film webs, be arranged in a direction perpendicular to the direction of transport, the number of correspondingly many conveying devices for the closure and bottom film webs, as well as as many devices for producing puncture openings and as many first and third sealing devices. This results in a device with multiple benefits, which in turn increases the productivity of the device.
  • the device can have a longitudinal cutting device for cutting the beverage containers to be produced which are arranged next to one another on the film webs.
  • the device also has a test device after the first sealing device, for differential pressure measurement, in order to check the welding point around the puncture opening.
  • the test device monitors the function of the first sealing device during production, so that the production of bags in which the puncture hole has not been properly sealed again is excluded.
  • Fig. 1 shows a schematic representation of a device for producing a beverage container as shown for example in Figs. 4 and 5.
  • the films required for the production of the beverage container are wound on the front film supply roll 14, the closure film supply roll 13, the bottom film supply roll 27 and on the rear film supply roll 15.
  • transport rollers 30 With the help of transport rollers 30, the individual film webs are each pulled in the transport direction T from the respective supply rolls. So that the individual film webs can be guided taut, tensor rolls 16a, 16b and 16c are arranged behind the supply roll for the front film 14, the supply roll for the sealing film 13 and the supply roll for the back film 15.
  • a tensor roller system (not shown) can also be provided for the base film.
  • a length compensation 17 is provided for the front and rear side film webs 1, 12.
  • a device 8 is provided for creating a puncture opening 3 in the front film web 1. The device 8 completely punches the puncture opening 3 (FIG. 5) through the front side film web 1.
  • the closing film web 2 is transported to the front side film web 1 via deflection rollers (not shown) and guided parallel to it.
  • a first sealing device 9 is arranged around the front side and sealing film web running parallel to one another, in order to weld the sealing film web 2 around the puncture opening 3, for example in a circular manner, to the inside of the front side film web 1.
  • a test device 10 is after the first Sealing device 9 is arranged and monitors the function of the sealing device during ongoing production, so that the production of bags in which the puncture hole has not been properly sealed again is excluded.
  • Deflection rollers (not shown) can also be arranged, which feed the rear foil web in the transport direction so that the inside of the front foil web 1 welded to the moving foil web 2 faces the inside of the rear foil web 2, and that the bottom foil web 29 between the front foil and rear foil web 1, 12 is performed.
  • a bottom cooling 20 is provided which cools the sealing points.
  • a sealing device 21 for the side edges 5 of the beverage container to be produced is provided behind the floor cooling device 20.
  • the front-side film web and the rear-side film web are welded together along the side edges of the beverage container to be produced, including the closure film web 2.
  • side edge cooling 22 to cool the sealing seams.
  • a device for die-cutting 23 is provided, which for example stamps round corners of the beverage container out of the foils welded to one another.
  • the film webs welded together are cut into strips of bags which are connected at their side edges 5.
  • a cross cutter 31 separates the side edges 5 of the individual Bags from each other.
  • the transport device 30 is located between the longitudinal and cross cutter 24, 31. Downstream of the device is a bag packer 26, which packs the empty bags fully automatically into stackable containers and transfers them to a conveyor, where they can then be filled and closed.
  • bags can also be produced in which the front and back side films are simply welded together along the bottom edge 6b of the bag.
  • a sealing device is then provided for welding the front and back film webs to the bottom edge of the bag instead of the sealing device for the bottom film web.
  • the individual film webs are transported intermittently, i.e. that the transport device 30 always moves the respective film webs by a certain distance, which preferably corresponds to a bag width.
  • an additional transport device not shown, is provided for the sealing film web 2, which runs synchronously with the first transport device 30. This additional transport device prevents excessive tension on the sealing film web 2.
  • the individual stations 8, 9, 10, 19, 20, 21, 22, 23, 24, 31 are arranged with respect to one another in such a way that a bag to be produced comes to lie in each station when the respective film webs are transported by a cycle length, for example a bag width . So there is a continuous Production process that is not disturbed by the attachment of the sealing film web.
  • a plurality of beverage containers to be produced individually can also be provided next to one another, perpendicular to the direction of transport T, on the front or rear side film 1.12.
  • 4 beverage containers to be produced are arranged next to one another, each of which adjoins one another with their upper and lower edge 6a, b of the bag.
  • the bag packaging is therefore produced on a machine with four uses, i.e. four beverage containers are manufactured simultaneously in one machine cycle.
  • the front-side film web 1 is guided intermittently via the deflection roller 7 to the device for producing the puncture opening 8.
  • puncture openings 3 are simultaneously created in the front-side film web 1.
  • the four sealing film webs are guided over the deflection rollers 32 in the transport direction to the front film web 1, so that the sealing film web 2 and the front film web 1 run parallel to one another.
  • the four sealing film webs 2 and the front film web 1 are then transported to the sealing device 9, wherein each sealing film web 2 on the inside of the front film web 1 is welded, for example in a circle, around the respective puncture openings 3, thereby creating a film arrangement as shown in FIG. 2 .
  • the front-side film 1, to which the four sealing film strips 2 are welded around the puncture opening 3, are then transported to the testing device 10 so that the welding points can be tested.
  • the front-side film 1 provided with the closure films 2 is then directed over a deflection roller 11 and a rear-side film web 12 is also in the transport direction T. steered via a deflection roller 11, so that the inside of the front film web 1 faces the inside of the back film web 12. If it is a matter of producing beverage containers with a separate bottom part, four bottom foil webs can be transported along the arrow P between the front and rear side foil web in the bottom region of each individual bag to be manufactured in the transport direction and, as already described, welded.
  • the four beverage containers 28 to be produced arranged next to one another are welded to one another along their side edges 5, as has already been explained in connection with FIG. 1.
  • the sealing film web 2 is not only held by the weld 4 around the puncture hole 3, but is simultaneously held by the welds on the side edges 5 of the beverage container.
  • the welded film webs are then cut into the individual beverage containers with the aid of rip and cross cutters 24, 31.
  • the sealing film web 2 does not have to be welded around the puncture opening 3 in a ring-shaped, angular manner, but can also be welded to the front film web 1 over the entire surface.
  • the individual bags are then passed on to a bag packer in order to finally be filled and closed completely.
