Definitions

  • the invention relates to a cross cutter for web materials, especially paper.
  • a cross cutter for corrugated cardboard has become known, which has a knife roller, which has the shape a tube made of carbon fiber composite material. On this A knife holder is attached to the tube by means of screws. The Storage and drive takes place via existing metal Bearing stubs that are incorporated into the tube.
  • a knife shaft become known, the outer shell of a metal hollow profile, especially made of aluminum, which has a Inner shell made of fiber composite material runs around. There is the knife carrier is formed in the outer shell.
  • For storage shaft journals are attached in a torsionally and flexurally rigid manner.
  • the knife shafts over non-uniform speed gearbox or preferably via controllable electric motors with large acceleration and braking torques non-uniform to drive.
  • the speed of the knife shafts becomes Cutting a format that is longer than that by the Scope of knife waves certain synchronous format, in the course one turn braked and at the time of the cut accelerated again to the web speed. It is also possible by periodic acceleration to a peripheral speed shorter above the web speed Formats to cut as the sync format.
  • the basic parameters of required cutting lengths and the possible acceleration and Braking values determine the synchronous cut length, i.e. the Knife shaft diameter.
  • the object of the invention is a cross cutter for web materials to create a wide range of variations the synchronous cut length and all requirements with regard to the structure, in particular the attachment of the knife shaft, the possibility of applying the enormous torques and sufficient torsional and flexural rigidity for the Knife shaft allowed.
  • the knife roller made of light metal is very similar shaft cross-section to be designed favorably the smaller Modulus of elasticity compared to steel with regard to torsion and Bending stiffness. At the same time, it enables compared to a lightweight construction using carbon composite materials (CFK) a direct attachment of the Knives on the knife roller, which would not be possible with CFRP.
  • CFRP carbon composite materials
  • Knife beds made of steel would have to, for reasons of stability be provided by the large knife flight circle cause excessive inertia and attach it to the knife roller is problematic and weakens it.
  • the peak values of the drive torque and the corresponding one Braking torque is around 5,000 Nm. They are too Bending moments due to cutting force. These powers require a firm and secure fit of the shaft bearings and the synchronous wheels transmitting the drive. This is with a shaft end structure made from the material of the knife roller, So light metal, especially aluminum alloy, not too to reach. In the invention, therefore, the shaft ends are off a material with high strength, especially steel, manufactured.
  • the difficult problem to fix between the light metal knife roller and the steel shaft ends requires special measures in the invention are formed by the flange that practically over the entire circumference of the knife roller is sufficient and for a non-positive and / or positive connection.
  • both non-positive and positive Connection especially for both types of connection are designed so that they alone drive torque could transmit.
  • training of the shaft end with a flange at both ends of the knife shaft could be provided with one-sided arrangement of the drive only the drive-side shaft end must be connected in such a way because in addition to the bending moments there is also the drive torque is to be transferred.
  • connection between the flange and the essentially cylindrical knife roller can be frictionally engaged respectively.
  • circular cylindrical recesses which runs longitudinally over the knife roller
  • Fastening screws can be inserted into these sockets be screwed into the face of the flange press the knife roller.
  • these can be slightly opposite the face of the cutter block are recessed so that the flange is only on the end face the knife roller and not on those of the bushings.
  • the knife roller can have several, also over the Scope distributed, have recesses for dowel bolts that fitted in and in the flange and if necessary by locking screws are secured. They form a form-fitting Connection.
  • the various connecting elements on the knife roller i.e. the socket recesses just like the dowel pin recesses and the continuous Central bore, which preferably receives a centering pin, can be arranged so that they have a profile an extremely rigid and torsionally rigid design for the knife roller result.
  • the four Bushing recesses evenly distributed over the circumference be arranged between two of them a knife carrier recess lies and the recesses for the fitting bolts in contrast, offset by approx.
  • a cross cutter 11 of which only part of the housing is indicated, and which is a so-called Folio cross cutter is in bearings 12 is a knife shaft 13 stored. It cuts in cooperation with you accordingly, i.e. trained essentially the same Counter knife from one path, from several, from different Upcoming paper roll bearings exist, relatively large Sheets of paper that are subsequently, e.g. in giants or stacks of paper collected on pallets.
  • Knife shaft 13 which consists of a multi-stepped pin 15 and a flange 16 integral therewith intervenes Drive 17, to which a synchronous gear 47 belongs, the is rotatably attached to the shaft journal.
  • This gear meshes with a corresponding synchronous gearwheel with the shown cutter shaft 13 cooperating cutter shaft.
  • synchronous wheels at both ends of a knife shaft intended.
  • the drive from the drive motors can either directly on the shaft journal 15 or via the synchronous gear respectively.
  • the cutting area 48 of the knife shaft extends to that pin-side end of the flange 16. Up to there forms the Outer periphery 18 of the flange the immediate continuation of the Surface of a knife roller 19, which most of the Occupies the cutting area.
  • the knife roller consists of a circular cylindrical section made of an aluminum alloy (see Fig. 3), in the outer circumference opposite to each other Recesses 20 in the manner of approximately longitudinal Grooves for knife holder 21 for attaching the lighter Knife 22 clamped to the axis is provided is. The clamping takes place via a clamping wedge 23, which Knife in the area of its thickening away from the cutting edge Tight foot.
  • the clamping wedge 23 is by screws 53 into the trapezoidal ones narrowing in cross section Recesses 20 drawn into it.
  • the recess 20 (knife groove) lined with a steel strip 54, which for a uniform Distribution of the contact pressure without plastic deformation worries.
  • Knife takes place over a multitude of arranged side by side and approximately tangentially directed adjusting screws 24, in corresponding threaded holes 25 in the knife roller 19 are screwed in.
  • the knife carrier recesses 20 and the knife 22 also extend over the outer circumference of the flange 16 away, so that this is an active part of the knife shaft forms.
  • the knife attachments, e.g. the clamping wedges 23, additionally act like pass wedges that are described later Support flange / knife roller connection.
  • Fig. 3 also shows that the made of solid material Knife roller has a plurality of longitudinal bores all run parallel to the axis of rotation 26 of the cutter shaft 13.
  • the socket recesses 27 form. They have a relatively large cross-section, e.g. between 25 and 40% of the knife roller diameter and so are arranged that their axes 28 on the corners of an imaginary Squares. This is arranged so that the knife holder are approximately in the extension of the webs 29, which are form between the socket recesses 27.
  • 3 are the recesses 20 somewhat laterally in between each two socket recesses 27 forming solid material gusset 49 shown what results from the oblique course of the knife carrier recess 20 results.
  • dowel pin recesses 30 is provided, which is relatively close to the circumference 18 of the Knife roller are provided. They are an extension of the Crosspieces 29 between socket recesses 27, which are at right angles the previously mentioned webs.
  • bushing recesses are also relatively close to the circumference 18 reach is an area in the middle of the cross section formed, which occupies a central recess 31 which is coaxial extends to the axis of rotation 26.
  • the cross section of the knife roller 19 thus has its solid material sections that have remained between the recesses the shape of a central central recess 31 wheel arranged around it with hub, four spokes (webs 29) and a peripheral, largely closed edge area 32 like a wheel tire.
  • the socket recesses are located here 27 regularly distributed around the axis of rotation 26 and compared to smaller dowel pin recesses on the one hand and the recesses 20 for the knife are on the other hand each in the gaps in between, so that there is largely self-balanced and especially with regard to the Main stresses (torsion and bending) stable, on the other hand but in terms of inertia and weight, which in the bend comes in, gives almost ideal structure.
  • the invention is the most important part in a cutter shaft forming a cross cutter a principle redundancy reached.
  • a material for the knife roller can instead the preferred aluminum alloy every other technically available light metal can be used. Because of the special Connection method between the light metal body of the Knife roller and the shaft end 14 with steel pin 15 and Flange 16 ensures that in particular the aluminum material nowhere too high becomes. So it cannot be plastic or impermissibly large elastic deformations occur.
