Definitions

  • the invention relates to a device for severing a material web, in particular a paper or cardboard web that contains a circular knife as the cutting element, the a transport carriage is rotatably supported by means of a drive on the Cutting section is movable.
  • Such devices are known to be components of splicing devices that in the case of unwinding devices for winding rolls made of paper or cardboard webs, the end of the Connect the outgoing material web to the start of the web of a new winding roll. she serve the end of the running path and / or the beginning of the new path cut off, so that a connection of the two webs with little or no Overlap can be made.
  • DE 199 23 097 A discloses a device of the generic type. It contains a circular knife as a cutting element, which is rotatably mounted on a trolley is that across the web width by means of a linear drive unit as a travel drive is movable. The circular knife is also used to cut against one on the cart attached counter roller moves.
  • Circular knives freely rotatably mounted which when cutting the web only through the Friction with the web are rotated with certain types of paper or cardboard unable to sever the web safely. Especially at the beginning of the Cutting process, when the circular knife dips into the path at the edge of the path, at freely rotating circular knives Problems with the cut occur.
  • the invention has for its object a separation device of the generic type Art to improve so that a safe cut through without great design effort the web is also guaranteed at the edges of the web.
  • the circular knife thus has a rotary drive which improves the cut quality is driven by the travel drive of the transport carriage.
  • a separate, independent one Rotary drive with energy supply is not required.
  • the separating device is part of a splicing device for connecting very wide (8 m and more) paper or cardboard webs, like them is described in DE 199 23 097-A. It is used to cut the web 1 across their direction of travel.
  • the separating device for cutting through is also narrower Lanes can be used.
  • the cutting device contains a circular knife 2 as the cutting element, which is freely rotatably mounted on a transport carriage 3. As shown in Figure 3, is the transport carriage 3 with the knife 2 mounted thereon by means of a travel drive in both directions can be moved linearly across the cutting path transverse to the web running direction.
  • a is used as the drive for the transport carriage 3 between the deflection rollers 4 tensioned circulating belt 5 to which the in a Guide running transport carriage 3 is clamped.
  • One of the pulleys 4 is with a rotary drive connected to the belt 5 with the transport carriage attached to it 3 moved in both directions across the web 1.
  • a powered one Band 5 can also be used other linear drives, for example one Linear drive unit, whose driver is connected to the transport carriage 3 or a rodless cylinder extending over the cutting distance.
  • the rope 6 Parallel to the cutting section, that is to the travel section of the transport carriage 3, and with A short distance below the level of the web 1 is a rope across the working width 6 excited.
  • the ends of the rope 6 are on one machine side at the Housing 7 of the splicer attached.
  • the rope 6 is preferably in the longitudinal direction elastically deformable or spring-loaded so that it runs in a straight line under tension.
  • the present exemplary embodiment uses a rope 6 made of polyamide (nylon) of 0.5-1 mm Diameter used at one end via a tension spring 8 on the housing 7 is attached.
  • the tension of the cable 6 can be adjusted by means of the tension spring 8.
  • the rope 6 is guided in a wrap of 360 ° around a pulley 9, which on Carriage 3 is freely rotatable. A linear movement of the transport carriage 3 leads thus to a rotational movement of the sheave 6. By a lateral displacement and a To prevent the rope 6 from jumping off the sheave 9, the rope 6 is in one circumferential circumferential groove 10 of the pulley 6 out.
  • the Pulley 6 coupled with the circular knife transmitting 2 torques.
  • the circular knife 2 coaxially attached to the outside of the rope pulley 9 and has a little larger outer diameter than this, so that the cutting edge of the circular knife 2nd protrudes radially.
  • the circular knife 2 has one Outer diameter of approx. 60 mm
  • the pulley 9 has an outer diameter of approx. 50 mm.
  • the pulley 6 is preferably on a journal 12 via ball bearings 11 stored, which is attached to the transport carriage 3. To cut it on the Cable pulley 6 attached circular knife 2 moves against a counter roller 13, which also is freely rotatably mounted on the transport carriage 3.
  • the Travel drive of the transport carriage 3 thus also acts as a rotary drive for the Circular knife 2, which is activated simultaneously with the movement of the transport carriage 3. If the transport carriage 3 is started outside the web width, the rotary drive acts of the circular knife 2 already when the circular knife 2 is immersed in the web 1 the edge and thus ensures a safe cutting of the web 1.
