Definitions

  • the present invention relates to a device for Removing part of a sheet-like film material.
  • the film material can be a single-layer or Be multi-layer material and for example on one Roll body may be present coiled. From this reel body such a path can be drawn off and in one clocked or continuously running work processes processed such as deformed. Corresponding Depending on the application, it may be necessary Detach parts of your sheet-like film material.
  • the invention is based on this prior art based on the task of being economically viable Possibility to separate partial areas from one specify sheet-like film material, in particular also in moving foil material.
  • the devices according to the invention stand out accordingly from either a cutting edge in a rolling motion through the film material web is pushed through or that a cutting edge in one pulling cut pulled through the film material web becomes.
  • Both devices have the advantage that the necessary compressive or tensile forces to Cutting the film material are relatively small. This has result in the corresponding devices comparatively slim and therefore easy to train can. These devices are therefore well suited while the separation process, for example, with the in the transport direction moving track to be moved.
  • the cutting edge can get stuck next to the knife edge be arranged elastically compressible buffer part.
  • this buffer part compresses and relaxes again when moving out this area of the cutting edge from the film material web.
  • the severed sheet of film material from the cutting edge or knife edge moved away. This will prevents the severed area of the film-material web Attach to the side of the knife edge can.
  • the knife edge can form a self-contained ring be shaped to provide a desirable complete detachment of the respective sub-area from the film material web enable.
  • This knife-cutting ring can be used for better Handling the device attached to a plate be attached. This makes it possible to have a roller from above to let it roll over the plate and thereby circumferentially through the knife edge ring To push the film material web through.
  • the film material web is the collar-like edge area one with a liquid or pasty Filler filled bag.
  • this border area is a lower track, which deforms into a pot-like container and is filled with the filler, with an upper sheet that forms the lid of this pot-like container, filler-tight connected.
  • Devices can then be used in a railway area separated several pot-like containers from the web become. During the separation process, the device is connected moving with the moving train.
  • Embodiments are also shown in the drawing another device where the cutting edge not in a rolling motion but in a pulling motion Cut is pulled through the film material web.
  • Embodiments for this include, for example, that the Knife edge perpendicular to the film material first in the Foil material is moved in and then the knife edge is brought into rotation about an axis of rotation.
  • the axis of rotation is the center of an arc.
  • Knife edge of such a device in the floor plan already be shaped like a circular arc.
  • the cutting edge can a serrated edge or a serrated edge have.
  • a hold-down in addition the knife edge must be present against the film material can be pressed.
  • This hold-down holds the Film material web immovable during the cutting process firmly.
  • Such a hold-down can also in Interior that is driven by the circular rotating Knife edge is enclosed, can be arranged.
  • the knife edge is used to create a pulling cut present on a rotary cylinder. It can the knife edge or the rotary cylinder perpendicular to the film material so that they are in the film material moves in.
  • the knife edge can be a razor blade.
  • the longitudinal axis the razor blade is at an acute angle to the plane the sheet of film material arranged to the desired one to allow pulling cut.
  • a separation station 10 shown in detail in FIG. 1 is part of a machine system by means of which a lower Film web 12 and an upper film web 14 treated in this way are that the lower track 12 to pot-like containers 16 deformed, filled with filler 18 and by means of the upper Lane 14 was closed.
  • the resulting Foil material web 20 thus has separate ones Areas that represent pot-like containers 16.
  • the pot-like containers 16 are defined by edge areas 22 separated from each other. In these edge areas 22 are the two tracks 12, 14 firmly connected. in the In the present case, the two lanes are water-soluble are welded together in the edge regions 22. In the film material web 20 becomes these edge regions 22 separated, so that the pot-like containers 16 then are individually present.
  • Edge areas 22 represent a waste product.
  • the transport plate 24 moves via a mechanical substructure 25.
  • the transport plate 24 has the number of pot-like Containers 16 corresponding indentations 28, the size and shape of the containers 16 correspond.
  • each arch 28 leads to a branch channel 30 Cross channel 32, the line with a longitudinal channel 34th connected is.
  • a line 36 leads from the longitudinal channel 34 a vacuum generator 38. With the help of the vacuum generator 38 can create a negative pressure in the arch 28 become.
  • the Track 20 in the vaults 28 and thus on the Transport plate 24 fixed in position.
  • a roller body 40 is present, which in Roll direction 42, that is in the transverse direction, over the Transport plate 24 can be rolled away.
  • the roller body 40 presses from above on a stamping plate 44 on.
  • the stamping plate 44 consists of a plate 46 on the attached to the bottom 48 rings cut into rings are attached.
  • the free edge of each ring 48 forms the respective cutting edge 51.
  • the subsequent lifting out of the pot-like containers 16 from the transport plate 24 can for example via suction devices respectively.
  • 6 and 7 are rotating body 50 in the separation station 10 with which the individual pot-like containers 16 are separated from the film material web 20 can.
  • Each rotating body 50 has a plate part 52, to which an annular cutting edge 54 is attached, projecting downward is.
  • the free edge of the ring cutter 54 forms the Cutting edge 51.
  • the rotary body 50 can by one central axis of rotation 53 are set in rotation (Arrow 56).
  • the rotating body 50 can be be moved vertically onto the film material web 20 (Arrow 58).
  • annular outer Hold-down device 66 available at the bottom of the ring-shaped Hold-down device 66 is an elastically flexible material 68 available. With the help of this material 68 the Foil material web 20 firmly on the transport plate 24.1 held while she, the web 20, by the ring cutter 54 is cut.
  • an inner hold-down 72 may be arranged in the Interior 70, which is enclosed by the ring cutting edge 54.
  • an inner hold-down 72 may be arranged in the Interior 70, which is enclosed by the ring cutting edge 54.
  • the vacuum generator 38 still acts a sheet of film material 20, the same in the Arches 28 of the transport plate 24.1 keeps sucked.
  • Knife edge in the form of a razor blade 80 In the embodiment shown in Fig. 7, the Knife edge in the form of a razor blade 80.
  • the razor blade 80 is arranged with its cutting edge 82 so that they make an acute angle 84 with the surface the film material web 20 forms.
  • fastening points 86 of the razor blade 80 on the rotating body 50.7 arranged accordingly.
  • inner and outer hold-downs 66, 72, as in Described in connection with Fig. 5, can be provided.
  • the serrated edge 62 or the serrated edge 64 could be dispensed with and instead the plate part 52 (FIG. 5) also at an acute angle 84 to the film material web 20 are arranged. Maintaining the axis of rotation 53 would then also be a pulling cut on the plate part 52 existing cutting edge 54 through the web 20 through it. Then they were comparable Ratios as in the razor blade 80 exist.
