Definitions

  • the proposed device relates to the displacement of lower knives for cutting webs of paper, foil, fabric, plastic, metals or the like in their running direction, these lower knives being mounted on a shaft supporting them and means for holding the respective, in particular sleeve-like Lower knife are provided in a desired position.
  • a device of this type can be found, for example, in DE-B-1 802 305.
  • the so-called lower knives are each driven by their own motor and, with the help of an air cushion, are moved to the desired position across the width of the web to be cut, on a guide arranged transversely to the running direction of the web.
  • DE-B-1 802 305 it is possible to move the lower knives to the desired position for a particular cutting process in a smooth manner.
  • the web to be cut into individual strips runs essentially tangentially between the respective lower knife and the respective upper knife, that is to say is used to produce a so-called tangential or straight cutting process.
  • the present invention deliberately turns away from this train of thought in order to be able to fulfill the task of also being able to move cutting sleeves of the type in question by a division of the cutting edges incorporated into them in a smooth manner.
  • At least one second groove or a plurality of second grooves can be incorporated into the shaft carrying the cutting sleeves, the first groove (s) relative to the second groove ( en) can be arranged offset to one another in the circumferential direction of the shaft and an expandable chamber, hose or the like can be inserted into each of the second grooves, which expands the respective cutting sleeve radially from the inside and can be filled with a pressure medium.
  • At least one upper knife 1 and one lower knife 2 are rotatably mounted in a machine frame 3.
  • This machine frame can for example consist of two mutually parallel side walls, between which the upper knife 1 and the lower knife 2 are rotatably mounted on these supporting shafts.
  • a plurality of knives in the viewing direction of FIG. 1 can also be used Weil be arranged one behind the other so that a web to be cut can be cut into at least two or more strips in their running direction.
  • the web 4 for example coming from a rolling device, can be cut into a plurality of strips 5 with the help of the knives 1 and 2, these strips being arranged one behind the other in the direction of view of the viewer of FIG. 1 and running out of the cutting device in the direction of the arrow 6 to be fed to a winding device, for example.
  • the dashed path of the web 4 and the strips 5 cut therefrom is essentially horizontal, i.e. "Straight", whereas the continuous line 7 and the strips 8 cut from it at least partially wrap around the lower knife 2, as indicated by the angle 9, that is to say represent a so-called looped cut.
  • the strips 8 lying one behind the other in the viewing direction of the viewer leave the cutting device, for example in the direction of the arrow 10.
  • FIG. 3 shows a tubular shaft 11, which contains a supply channel 12 for a pressure medium in its interior.
  • This feed channel can have a much smaller diameter than shown in FIG. 3.
  • Bush-shaped lower knives so-called cutting bushes 13, 14 and 15, are mounted on the shaft 11 such that they are supported and held by the shaft 11.
  • the cutting sleeves in their entirety form the lower knife 2 of FIG. 1. Instead of three cutting sleeves, several or even only one or two cutting sleeves can also be arranged on the shaft 11.
  • first grooves 16, 17 and 18 are machined into the shaft 11. These first grooves maintain a pitch angle 19, 20 and 21 of, for example, 120 ° C.
  • Fig. 2 shows that second grooves 22, 23 and 24 are also machined into the shaft 11 and also maintain a pitch angle 25, 26 and 27 of, for example, 120 ° C with each other and that the two types of pitch angle with each other by one Angles 28 of, for example, 60 are offset from one another in the circumferential direction.
  • the exemplary embodiment shows three first and three second grooves. However, it is not absolutely necessary to maintain such a triad, for example only one type of groove is possible in each case or two or four or more grooves per type of groove, so that the pitch angle changes accordingly.
  • a fitting piece 29 is inserted into each of the first grooves, for example into the groove 16. It is firmly connected to the cutting sleeve 14 with the aid of screw connections 30 and 31, for example, in such a way that when the cutting sleeve 14 is displaced with respect to the shaft 11, i. when the cutting sleeve 14 is displaced in the axial direction of the shaft 11, is also displaced.
  • the radially inner surface 36 or at least a part of that surface of the cutting sleeve 14 and the radially outer surface 37 of the fitting 29 can be held slightly obliquely in a wedge-like manner, in order to allow an exact adjustability between the base 33 of the first groove 16 , the needles, rollers 34, the fitting 29 and the cutting sleeve 14.
  • the threaded bores of the screw connections 30 and 31 are formed, for example, as so-called fitting bores, which are drilled when the device is assembled. The thread is then cut into these holes when the respective cutting sleeve is assembled.
  • the cages 35 are shorter, for example, by the masses 38 and 39 than the axial extent 40 of the fitting 29 or the cutting sleeve 14.
  • This difference in the axial mass can be, for example, as large as a division 41, which two cutting edges of the cutting sleeve 14 adhere to one another.
  • the sum of the masses 38 and 39 to equal, for example, the distance which three cutting edges of the knife sleeve maintain from one another.
  • T-shaped pressure pieces 42 are inserted in their cross section, which reach through openings 43 of the shaft 11 and bear radially from the inside against the respective cutting sleeve.
  • At least one hose 44 is also let into each of the second grooves, the inside of which is connected to the feed channel 12 of the shaft 11 by means of at least one bore 45 each.
  • pressure medium for example compressed air
  • pressure medium can be introduced into the feed channel 12 in order to thereby expand the hoses 44, to move the pressure pieces 42 radially outward and in this way to hold the respective cutting sleeve at a desired position after the adjustment process.
  • each end face of each cutting sleeve with claws 47, toothing or similar devices, which are designed so that the be neighboring cutting sleeves can move against each other even if the claws of the adjacent cutting sleeves interlock. This would ensure that the web would not sag, but would also be supported at those points where there are gaps between the cutting sleeves. At the same time, any markings in the web to be cut or on the cut strips are prevented.
