Definitions

  • the present invention relates to a device according to the preamble of the claim.
  • the web to be cut into individual strips runs approximately tangentially between at least one upper and at least one lower knife, so that at least two strips result from a web in this way.
  • the straight cut the web to be cut into individual strips runs approximately tangentially between at least one upper and at least one lower knife, so that at least two strips result from a web in this way.
  • not only a pair of knives, but also several pairs of knives can work together to cut a relatively wide web into a plurality of relatively narrow webs.
  • the end processor of the web to be cut often requests webs of different widths, which is why there is a need to cut a relatively wide web during one production process, for example into relatively wide webs and during another production process into relatively narrow webs.
  • These cut webs are generally wound up into rolls so that they can be sent to the respective end processor of these webs in a simple and convenient manner, for example.
  • the changing requirements of the end processor mean for those who have to subdivide a relatively wide web into individual webs that the facility available to them must be changed accordingly. This process is usually referred to as «positioning.
  • EP-A 96 026 (WO 83/02083) pursues the goal of expanding a hub.
  • this aim is not aimed at by the proposed invention.
  • a widening of knife hubs is not up for discussion in the proposed invention. This also applies to the French patent application FR-A-23 40 170.
  • line 26 of DE-C 10 38 902 shows that with the device proposed in DE-C 10 38 902, cutting sleeves are to be tightened with the aid of an annular hose in such a way that they don't shift. Here, all cutting sleeves should be tightened.
  • a smooth movement of the knife in question is not considered, from which it can be seen that DE-C 10 38 902 pursues a goal which is completely contrary to the aim of the present patent request.
  • DE-C 10 38 902 is also unable to provide any suggestions as to how the knives in question could be moved easily.
  • the task is to propose a simple and smooth-running device for moving the knives or their holders, in particular those knives or holders for the so-called lower knife, in particular in the event that the lower knife at least partially from the web to be cut is entwined.
  • the present invention makes it possible to move the lower knife in the radial direction relative to the shaft supporting it within the play caused by the manufacture to such an extent that it can be moved in the axial direction of the shaft in a smooth manner.
  • This makes it possible to easily move even relatively heavy bottom knives, in particular so-called cutting bushes, from one position to another.
  • This in turn makes it possible to switch the entire device in question from one type of production to another in a simple and quick manner, i. H. for example from one width of strips to be cut to another.
  • a web 2 to be cut into several strips 1 runs through a pair of knives.
  • Each pair of knives comprises an upper knife 3 and at least one lower knife 4.
  • the upper knife (s) 3 is / are fastened on the shaft 5, while the lower knife (s) 4 are fastened on a shaft 6.
  • Each of the shafts 5 or 6 is rotatably mounted in a correspondingly designed machine frame and can also be driven.
  • the upper knives 3 can be moved along the shaft 5 - ie in the viewing direction of FIG. 1 - and the lower knives 4 along the shaft 6 as required. This shift can be relatively slight, especially when there are several intersections per undercutter.
  • bottom cutters can be designed in the form of so-called cutting sleeves, with each cutting sleeve containing a multiplicity of cutting edges.
  • One and the same upper knife can optionally work together with each of these edges, so that it is often necessary in so-called format changes to move the upper knife by a relatively wide axial extent, while the lower knife only by a much shorter length, in order to enable this that the upper knife can work with another cutting edge, a so-called cutting groove, than before.
  • a plurality of lower knives 4a, 4b, 4c etc. can be arranged next to one another on each shaft 6.
  • at least one axial bore 7 is machined into the shaft 6.
  • a ball valve 8 At one end of the bore 7 there is a ball valve 8, the other end is closed by a screw 9.
  • Radial bores 10, 11 and 12 open into the bore 7, the radially outer ends of which represent exit points from which the compressed air blown in via the ball valve 8 can escape. These exit points are designated 13, 14 and 15.
  • the exit points 13, 14 and 15 in FIG. 3 are arranged approximately in the middle of the respective lower knife, so that even if the respective associated lower knife should be displaced within certain limits in the axial direction of the shaft 6, the respective exit point of the respective lower knife is constantly covered. In other words, this means that the respective lower knife can only be displaced relative to the shaft 6 to such an extent that this lower knife just barely covers the respective outlet opening.
  • the radial bores 10, 11 and 12 are incorporated in the shaft 6 such that they come to rest in the upper half 16 of this shaft when the shaft is at a standstill with a sectional representation of the shaft.
  • a positioning device is provided which enables the shaft 6 to be stopped in an easily possible manner immediately before the respective positioning of the lower knives 4 in such a way that the bores 10, 11 and 12 come to lie in the upper half 16.
  • the positioning device consists, for example, of a pawl 17 which can engage in a corresponding recess or groove 18 in the shaft 6.
  • the pawl 17 can be snapped into the bore 18 with the aid of a compression spring 19.
  • a cam 20 it is possible to remove the pawl 17 from the bore or. Unlock recess 18.
  • a switch 23 prevents the machine from starting in the event that the pawl 17 blocks the rotation of the shaft 6.
  • the bore 18 is preferably made at one end of the shaft 6 so that most of the shaft 6 remains free to position the lower knife thereon.
  • the knives or knife bushings can be shifted by both small and long distances along the shaft 6, as long as only the respective knife covers the hole assigned to this knife. Due to the pressure medium emerging from the respective bore, in particular compressed air, the respective knife or the respective knife sleeve is lifted by small amounts relative to the knife shaft and is able to slide on a thin cushion of pressure medium inserted between the shaft and knife. For this, it is not absolutely necessary to work special chambers into the inside of the knife, the knife sleeve or the knife holder for receiving the pressure medium. For example, it is also possible to raise the knife, the lower knife sleeve or the knife holder within the play that is already predetermined by the mechanical production of the machine parts involved.
  • the respective upper knife work together with one edge during a certain cutting process and with another edge of the respective lower knife or the respective lower knife sleeve during another cutting process.
  • This either increases the service life of the lower knife bushing or, with simultaneous displacement of the respective lower knife bushing relative to the upper knife, makes it easier to produce strips of different widths from materials to be cut from a web.
  • the present invention aids in the changeover from one format to be cut and possibly wound up to another.
  • any cutting dust that may accumulate between the knife shaft and knife holder can be blown out of the device by the pressure medium, especially when using compressed air.
