Definitions

  • the invention relates to a device for cutting a tear strip from a tape and for applying it to a web of packaging material according to the preamble of claim 1.
  • Such a device is known for example from DE-PS 15 86 o93, in which work is carried out with a fixed knife and a movable knife to which suction air can be applied in order to separate the tear strip from a tape.
  • the movable knife performs a linear movement with respect to the fixed knife, so that the tear strip is essentially knocked off the tape by the two knife edges.
  • such a separation is undesirable.
  • the object of the present invention is to provide a device of the type mentioned in the introduction in which a striking cut is avoided.
  • the device shown comprises a fixed knife 10 with a cutting edge 11 and a support and guide surface 12 for a belt 13, which is conveyed by means of a conveyor 14 intermittently with a width equal to the length of the desired tear strip 15.
  • the support and guide surface 12 is arranged horizontally.
  • the device comprises a movable knife 16 which can be pivoted back and forth about an axis 17 by a predetermined angle, which is preferably in the range from 45 to 50 °.
  • a pinion (not shown) on axis 17, which meshes with a gear wheel (also not shown).
  • the movable knife 16 has a cutting edge 18, wherein the two cutting edges 11, 18 of the blades 1 0, 16 are arranged mutually inclined, preferably by about 1 °, and tendons form of a hyperboloid of revolution. Adjacent to the cutting edge 18 of the knife 16 open at its lower edge suction air openings 19 which can be connected to a suction air source, not shown, so that the detached tear strip 15 can be held and transferred by the movable knife 16.
  • the pivot axis 17, which extends in the longitudinal direction of the movable knife 16, runs parallel to the cutting edge 18 and is connected at both ends to an angle lever 20 (only one shown), which has a cam roller 21 at its free end, which has a curve (not shown) in FIG Intervention stands.
  • This curve serves to vent the movable knife 16 during its return stroke into the starting position, which is shown in FIG. 1, from the fixed knife 10, which is why this curve exerts a slight stroke on the latter via the cam roller 21 during the return stroke of the movable knife 16 , so that a ventilation in the order of 1/10 mm or the like is effected.
  • the pivot axis 17 is spatially arranged in such a way that in the end position of the fixed knife 16, the latter is the separated one Tear strip 15 holds in the plane of a packaging material web 22, which is fed via a corresponding guide 23, 24 and guide or conveyor rollers 25, 26 to a schematically indicated welding device 27.
  • the packaging material web 22 is conveyed intermittently, the belt 13 and the packaging material web 22 being essentially orthogonal to one another; however, the conveying direction of the belt 13 is arranged slightly obliquely to the longitudinal direction of the packaging material web 22, which in turn is guided to rise slightly when the belt 13 is conveyed in the horizontal direction to the horizontal, so that the cutting edge 18 of the movable knife 16 and thus the detached tear strip 15 in the end position of the movable knife 16 for applying the tear strip 15 to the packaging material web 22 is in the plane of the packaging material web 22, as shown in FIG. 2.
  • the tear strip 15 held until then by the suction air openings 19 is released by interrupting the suction air supply to the suction air openings 19 and fed together with the packaging material web 22 to the welding device 27, where the two are connected to one another. Between the tear strips 15, which follow one another in the longitudinal direction on the packaging material web 22, there remains a small distance in which the packaging material web 22 is later cut into individual sections.
  • the conveyance of the belt 13 in the horizontal direction and the packaging material 22 in a plane which is inclined to the horizontal only in the longitudinal direction of the packaging material web 22 is preferred.
  • the formation of the knife 1 0, 16 ensures a progressive, pulling and with respect to the cutting edges 11, 18 contact-free cutting of the tear strip 1o from the belt 13 and a flashing off the cutting edges 11, 18 when pivoting the pivotable about its pivot axis 16, diameter 16, wherein at Use of a gear drive for the movable knife 16 to select the stroke during ventilation so that the drive gear still remains in engagement with the pinion.
  • the tape 13 is fed by the desired width of the tear strip 15, after which the tear strip 15 progresses by rotation of the movable knife 16 separated from the belt 13 and held by suction air on the movable knife 16, so that the Tear strips 15 can be transferred into the plane of the packaging material web 22.
