Definitions

  • the invention relates to a method for the continuous production of folding boxes, as specified in the preamble of claim 1, and a corresponding device for performing this method.
  • Folding boxes are known which are provided with a removal window through which the consumer removes the packaged goods.
  • the folding boxes are pre-punched with a corresponding window opening that is torn open by the consumer.
  • window openings arranged in the packaging carton have proven to be disadvantageous because the nonwoven material that is pulled through can get stuck when removed from the window opening and thus the intended function that one towel takes the other when pulled out is no longer guaranteed.
  • folding boxes have been provided for the packaging of paper towels, in which a relatively large pre-punched opening of the carton is covered with a plastic film that has a smaller window opening. This plastic film is relatively soft, so there is no risk that the solid paper towel will tear at the window opening.
  • the plastic film that is glued to the pre-punched cardboard is not already provided with its window opening, but the window opening is merely punched out.
  • a glue application is applied to the corresponding point of the folded blank, so that when the cardboard is torn open, the pre-cut part of the plastic film is torn out with it and the finished opening in the plastic film is only created at this point.
  • the known method has the disadvantage that the adhesive is applied to the pre-punched opening in the carton the carton relatively close must be made on the edge of the opening, so that the glue does not extend beyond the plastics film and the g in zzifol- forming operation incoming carton blanks to the stick to the glue application.
  • this positioning of the glue application has the disadvantage that the filling material gets stuck on the protruding film in the packaging machine and can therefore cause machine malfunctions.
  • the object of the invention is accordingly to provide a method and a device for the continuous production of folding boxes with a glued-in removal window made of flexible film, in which no pre-punching of the plastic film is required and which allows the required accuracy in the positioning of the plastic film even without a special print mark control.
  • the inventive method provides that the stick-on sheet is peeled off as un g estanztes tape from a supply roll and is punched immediately prior to being diced into individual sections corresponding to the window opening. This takes place in cooperation with the machine or the roller, with which the individual sections of the plastic film are applied to the folding blanks. Because the units for punching the window opening and the roller for application of the plastic film sections are mechanically rigidly connected to one another and so that the individual sections of the plastic film can be precisely fitted, there is no need for a special print mark control which would otherwise be necessary for positioning the plastic film. In addition, the positioning is much more precise and tolerances cannot be added as in the known method. Furthermore, one operation is saved, namely the preparatory pulling off of a film that has not yet been punched, its punching with a punching roll and its subsequent rewinding to a supply roll of pre-punched film material.
  • the process according to the invention is carried out in such a way that the film strip is pulled off the supply roll with the aid of appropriate feed rollers, is guided past a rotating punching roll and is then divided into individual sections of a predetermined length with the aid of a rotating and a fixed knife.
  • the cut-off parts of the plastic film are gripped by a vacuum roller and applied by it to the folding blanks provided with the glue application.
  • the device provided for executing this method has a drive pinion on the rotating knife, which drives a corresponding pinion of the punching knife roller.
  • An intermediate pinion is preferably arranged between the pinion of the rotating knife and that of the punch knife roller. Because of this direct mechanical transmission of the movement of the rotating knife to the punch knife roller, there is an immediate, unchangeable assignment between the positioning of the punched window opening and the beginning or end of a single film section. A special control for cutting the film is not necessary.
  • Figure 1 shows schematically a device according to the invention, which is used to carry out the method according to the invention.
  • a transport device 9 for example a conveyor belt, which transports the individual folding blanks to the cliché roll 8.
  • the cliché roll 8 is provided with glue from a glue supply 22 via an application roll 21.
  • the rotating cliché roller 8 transfers the corresponding layer of glue to the intended locations of the folding blanks 1.
  • the device further comprises a supply roll 3, on which a still unpunched film strip 2 is wound.
  • This foil tape 2 runs between a free-running counter roller 18 and the punch knife roller 4.
  • the punch knife roller 4 is driven by the pinion 10 of the rotating knife 5 via a pinion 11 and an intermediate pinion 13 mounted on an intermediate shaft 12.
  • the film 2 is pulled off the supply roll 3 by the corresponding feed.
  • the foil is cut into individual sections between the rotating knife 5 and the fixed knife 6. These sections are captured by the vacuum roller 7. It has individual openings on its outer surface and a negative pressure prevails in it, so that the film adheres to the outer surface of this vacuum roller. '
  • the individual sections of the film are applied to the folding blanks 1 by the vacuum roller. They are then transported on by the transport device 9.
  • Figures 2 and 3 show a partial section of the device according to the invention.
  • the punching knife 4 is mounted in two sliding blocks 14 and can be exchanged after the tensioning straps 15 have been pivoted away. These clamping tabs 15 are tightened with clamping screws 16.
  • the link guide 17 is mounted on the axis 19 of the counter roller 18. According to the dimensioning of the elongated hole 23, the link guide 17 can be pivoted. As a result of this pivoting movement, the toothed pinion 11 on the punching knife roller 4 is pivoted into and fastened in the intermediate pinion 13 mounted on the intermediate shaft 12. This intermediate pinion 13 is in turn, as shown in Figure 1, driven by the pinion 10, which is attached to the rotating knife 5.
  • the transmission ratios between the drive pinion 10, the intermediate pinion 13 and the toothed pinion 11 are, for example, 1: 1: 1.
  • FIG. 3 shows a section A-A according to FIG. 2. It can be seen that the punch knife roller 4 carries the punch knife 20 in its center and is interchangeably mounted in sliding blocks 14. The counter roller 18 is attached to an axis 19, for example wedged.
