Definitions

  • the invention relates to a cutting device for cutting a web, with a rotatable cutting cylinder, the has at least one first cutting blade on a circumference, which cooperates with a fixed second cutting blade, to cut the web in the transverse direction.
  • a cutting device of this kind is known in the art from EP 1 186 561 A of the Applicant known. These is used for cutting paper webs or film webs and has proven in practice in itself.
  • the cutting cylinder is with tapered roller bearings rotatably mounted on side plates.
  • Heat generated by the thermal expansion of the side plates a distance increase between the two Cutting knives causes. By this distance increase is the cut quality usually worse.
  • By downsizing This distance with warm machine may be the distance set again optimally and thus the desired high Cutting quality can be achieved again.
  • This difficulty has been solved by the installation of heated bearings.
  • such heated bearings cause significant Costs and installation problems.
  • the heaters need to preheat the side bearings preheated for several hours.
  • the invention is based on the object, a cutting device of the said type, which the said Disadvantages avoids and thus at high cutting quality the maintenance and the maintenance can be simplified.
  • the task is in a generic cutting device solved by at least one of the two cutting blades is formed own springing.
  • inventive Cutting device acts the self-locking cutting blade when Cutting process essentially like a spring and thereby This self-resilient cutting blade much more tolerant respect Distance changes between the two cutting blades. Cuts the self-springing knife with warm cutting device with required high quality, so it will be with cold machine and thus smaller distance between the Cutting knives will not wear out in a short time and may be one high cut quality can be achieved.
  • fixed cutting blade formed self-sprung. in principle but can also be attached to the cutting cylinder first Cutting knife be designed self-springing.
  • the self-sprung Cutting knife at least one recess.
  • This recess is in accordance with a development of the invention a Slit extending at least parallel to a cutting edge extends and in which this cutting edge can spring.
  • the Slot is preferably formed to be between two Cutting edges runs.
  • the self-sprung Cutting knife two slots on and each of these slots is arranged between two cutting edges when cutting in the common slot einfedern.
  • the self-locking cutting knife has four Cutting edges, which changed by turning the cutting blade can be.
  • Also in this version is each provided that a non-active Cutting edge rests against a stop surface and thus the eigenfedernde Cutting knife positioned.
  • the self-resilient Cutting knife created a cover bar, which is a front Edge, which is substantially parallel and at a distance runs to a cutting edge.
  • the cover bar can be the active cutting edge and thus the springy area the cutting blade to be stabilized.
  • the Sliding cover movable, so unwanted vibrations the resilient portion of the cutting blade effectively prevented can be.
  • the eigenfedernde Cut off knife This will be a resilient area created, which is held so that it is free-standing.
  • the self-locking cutting blade preferably two cutting edges, which can be changed.
  • the eigenfedernde Cutting knife at least in the area of an active cutting edge comparatively thin and in this area free-standing.
  • This cutting blade preferably has also four cutting edges.
  • the cutting device 1 shown in Figures 1 and 2 is used for cutting an endless web 12, in particular a paper web in equal sections.
  • the transport of the web 12 takes place continuously in the direction of arrow 13, these being Rail 12 is pushed and pulled.
  • Means for transportation the web 12 are well known to those skilled in the art and need it here not to be explained.
  • the web 12 is thus transported in the direction of arrow 25 from left to right.
  • a cutting cylinder 8 To cut the web 12 transversely to the transport direction has the cutting device 1 a cutting cylinder 8, the order a rotation axis 10 in the direction of arrow 11 continuously is turned.
  • the drive for turning the cutting cylinder 8 and the side plates and bearings for this cutting cylinder 8 are known per se and not shown here.
  • At a circumference 9 of the cutting cylinder 8 is at least one bar-shaped cutting blade 4 attached, the at least one Cutting edge 14 has.
  • This cutting edge 14 is at least as long as the web 12 is wide. The width is for example in the range of 520 to 740 mm.
  • the cutting cylinder 8 has at least one cutting blade 4. He can, however Also have several such cutting blade 4, so also comparatively narrow strips cut out of the web 12 can be.
  • the cutting blade 4 operates with a likewise bar-shaped Cutting knife 5 together, which is fixed to a carrier 15 is stored.
  • a carrier 15 For positioning the cutting blade 5 on the carrier 15, this has a stop surface 22, on which the Cutting blade 5 rests with a surface 23.
  • the cutting knife 5 is also flat on a surface 31 of the carrier 15th at.
  • the cutting blade 5 is provided with two slots 20 and 21, preferably over the entire length of the bar-shaped Cutting knife 5 extend and each end face are open.
  • the slot 20 is located substantially centrally between two cutting edges 18b and 18a, the Cutting edge 18b calmed down and the cutting edge 18a is active.
  • the region 33 is calmed according to Figure 2, while the Area 32 to the slot 20 is deflected out. That's true Cutting knife 4 on the cutting edge 18 a, so this can in Press in the direction of arrow 19 in the slot 20.
  • the deflection in the direction of arrow 19, however, this is comparatively small and is a few hundredths of a millimeter.
  • the cutting blade 5 can be turned so that the cutting edge 18 a is in the area of the stop surface 22 and thus calmed while the cutting edge 18b is active.
  • the cutting blade 5 has a further slot 21 and two further cutting edges 18c and 18d. Overall, this has Cutting knife 5 thus four cutting edges 18a, 18b, 18c and 18d. All cutting edges can be changed.
  • the Regrinding takes place on the surfaces 23 and 24, respectively simultaneously two cutting edges can be ground off.
  • the cutting blade 5 has a surface 26 which is flat and parallel to the surface 31 of the carrier 15 is.
  • a cover bar 16 on the cutting blade 5 at.
  • a front edge 17 of the cover bar 16 runs parallel to the cutting edge 18a.
  • the cover bar 16 is displaceable, that the distance of the edge 17 adjusted to the cutting edge 18a can be. This is an optimal support of the resilient Area 32 possible.
  • the two cutting blades 4 and 5 and the cutting edges 14 and 18a are generally not parallel to the axis. in principle However, an axially parallel arrangement is possible.
  • the cutting blade 5 is thus self-springing and thereby becomes achieved that the cutting blade 5 acts like a spring and is considerably more tolerant of changes in distance. Emotional the axis 10 as a result of temperature changes to the Side signs up or down, such may Changes in distance due to a resilient deflection of the cutting edge 18a without significant additional wear and without Reduction of the cut quality at this cutting edge 18a be recorded. This can reduce the service life of the cutting blade 5 are significantly extended.
  • the cutting blade 5 is inherently springing educated. Basically, alternatively Cutter 4 self-springing and the cutting blade 5 rigid be educated. Basically, a design is conceivable, in which both cutting blades 4 and 5 formed own spring are.
  • FIG. 3 shows a cutting device 2 according to a variant, in which a self-locking cutting blade 6 at a Carrier 15 'is mounted.
  • the carrier 15 ' has in the region of Cutting edge 27 has a recess 28 which a deflection the cutting edge 27 allows.
  • the cutting blade 6 is comparatively thin, what the said elastic deflection allows.
  • the cutting blade 6 is also on the Stop surface 22 is positioned. When the deflection rubs that Cutting knife 6 thus at the stop surface 22nd
  • FIG. 4 shows a cutting device 3 after another Variant, in which also a self-springing cutting knife 7 is provided.
  • the cutting blade 7 is offset and has two Cutting edges 29a and 29b, wherein the cutting edge 29a active and the cutting edge 29b is settled.
  • a gap-shaped gap 30 is provided, which is a deflection of the resilient portion 34 allows cutting.
  • a cover bar 16 is provided.
