Definitions

  • the invention relates to a support roller winding machine for winding material webs, in particular paper or cardboard webs, onto cores according to the preamble of patent claim 1.
  • Such winding machines are used for the production of winding rolls from the material web divided by longitudinal section. When winding, the winding rolls lie axially aligned on the two support rollers.
  • the air box can be swung down from an upper working position, in which its side surfaces lie sealingly against the support rollers, into a position below a support roller. The swiveling down creates space for a separate separating knife, which can be raised from below through the support roller nip, on the tear-off blade of which the web tears off when the full winding rolls are ejected.
  • the invention has for its object to improve a generic support roller winding machine so that a roll change can be carried out in a shorter time with space-saving design.
  • the arrangement of the cutting knife support with the tear-off blade in the air box takes up less space than a separate cutting knife.
  • the air box does not need to be lowered for a roll change. Lowering is only necessary to insert a new web or in the event of a paper jam.
  • the roll change can be carried out more quickly, since the tear-off blade of the separating knife can be moved up into its separating position in the roller bed without first swiveling the air box away.
  • the subclaims contain preferred, since particularly advantageous, embodiments of the invention.
  • Fig. 1 roughly schematically shows a side view of a section of a support roller winding machine according to the invention.
  • Fig. 2 is an enlarged view of a cross section through the air box with the cutting knife in the rest position
  • Fig. 3 shows a cross section in which the tear-off blade of the cutting knife is in the cutting position.
  • the support roller winding machine has two driven support rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers 4 lie on the support rollers 1, 2 during winding.
  • the material web 5, which is divided into individual webs in the longitudinal direction - preferably a paper or cardboard web - is deflected by the support roller 1 from below through the gap between the support rollers 1, 2 into the support roller bed 3 and wound there on sleeves 6 aligned.
  • the completely wound winding rolls 4 are pressed by an ejection bar, not shown, over the support roller 2 onto a lowering platform 7, from which the winding rolls 4 are lowered for unloading.
  • an excess pressure can be generated in the space delimited by the support rollers 1, 2 and the winding rollers 6 with compressed air.
  • an air box 8 with a compressed air supply is in the lower gusset between the two support rollers 1, 2 9 arranged, which extends over the axial length of the support rollers 1, 2 and the side surfaces facing the support rollers 1, 2 are curved in the upper part adapted to the lateral surfaces of the support rollers 1, 2, so that they can seal against them.
  • a plurality of axially extending felt strips are inserted on the outside, which seal the air box 8 against the support rollers 2 with minimal friction.
  • the air box 8 is attached to swivel arms 10 which are mounted in the frame of the machine. It can thus be lowered from its upper sealing position to a rest position - shown in broken lines in FIG. 1 - for example in order to introduce a new web 5. In the upper sealing position, its upper part extends to the narrowest point between the two support rollers 1, 2.
  • the upper boundary surface facing the support roller nip has an air outlet slot 1 1 which extends at least over the minimum web width and is on both machine sides as a guide surface for two End-side sealing elements 12 arranged on both sides of the machine are formed.
  • the shape of the end sealing elements 12 is adapted to the free cross-sectional area between the support rollers 1, 2, its upper part being elongated in a rectangular shape up to above the connecting line between the two vertices of the support rollers 1, 2, in order to provide a sufficient sealing surface for winding rollers 4 with a large diameter to back up. They are slidably mounted in the axial direction - that is to say transversely to the path 5 - on lateral pivot arms 13, the pivot axis of which runs somewhat eccentrically offset to the outside on the connecting line between the two carrier roller axes.
  • the sealing elements 12 can thus be pivoted out of the roller bed 3 over the support roller 2 into a position in which the lateral guide heads can be moved into the sleeves 6.
  • the low eccentricity means that the side surfaces of the sealing elements 12 facing the support rollers 1, 2 move somewhat away from the respective support roller surface when swiveling out, for example in order to be able to remove paper residues.
  • a separating knife 14 is arranged with a tear-off blade 15 which, in the sealing position of the air box 8, can be moved up into the roller bed 3 and lowered into the air box 8.
  • the tear-off blade 15 is lowered in FIG. 2, and in FIG. 3 it is in its separation position in the roller bed 3.
  • the tear-off blade 15 extends over the entire length of the feed slot 15, that is to say essentially over the entire machine width. It is attached to the end of a likewise machine-wide holder 1 6 in the form of a two-sided lever, which is articulated approximately in the middle at the end of a vertical support 18 about an axis 17 parallel to the support roller axes.
  • the support 18 is attached to the end of the piston rods 19 by vertical, hydraulic piston-cylinder units, the cylinders 20 of which are screwed onto the bottom of the air box 8 and are thus supported on the latter.
  • the cylinders 21 are fastened by pneumatic piston-cylinder units, the piston rods 22 of which extend vertically upwards.
  • the end of the piston rods 22 is connected in an articulated manner to the holder via lever 23 in such a way that the articulation points 24 with the holder 1 6, when the piston rods 22 are completely retracted, are somewhat offset relative to the articulation points 25 with the piston rods 22 in the direction of the supporting roller 2.
  • the tear-off blade 15 is clearly moved in the direction of the support roller 1 when the piston rods 22 are extended, as shown in FIG. 3. So that the holder 16 and the levers 23 can be stretched, the support 18 has cutouts in its upper part, into which these can be moved.
  • the end of the lever 1 6 facing away from the tear-off blade 15 consists of individual, spaced-apart tabs, one of the levers 23 being articulated alternately at the end of the respective tabs, or a freely rotatable wheel 26 being mounted.
  • the axis of rotation of the freely rotatable wheels 26 extends coaxially to the articulation points 24.
  • There are also recesses in the support 18 for the wheels 26 thus offset in the axial direction from the levers 23, into which they can be moved.
  • the lower part of the support 18 with the piston-cylinder units 21, 22 is guided on vertical guides 27 which are arranged in the upper part of the air box 8.
  • the entire cutting knife with its lifting mechanism is arranged in the air box 8. It is also possible to fasten the cylinder 20 of the piston-cylinder unit 19, 20 on the outside on the underside of the air box 8 and to guide the piston rod 19 in a sealed manner through the bottom of the air box 8.
  • the separating knife 14 can be divided into individual (for example four at 8 m working width) segments which are successively arranged in the axial direction. Each of these segments then consists of the parts which extend continuously over the segment width (tear-off blade 15, holder 16, support 18), which are moved up and down by two lateral piston-cylinder units 19, 20 and in which the tilting movement of the Tear-off blade 15 is effected by 2 lateral piston-cylinder units 21, 22 attached to the lower part of the support 8.
  • the end sealing elements 12 are pivoted into the roll bed 3 and moved axially against the end faces of the winding rolls 4.
  • the air box 8 is pivoted up so that the lower gusset between the support rollers 1, 2 is sealed and the sealing elements 12 can be placed on its upper boundary surface. They seal the air outlet slot 1 1 outside the winding roll area.
  • the compressed air supply is switched off, the end sealing elements 1 2 are pivoted out of the roller bed 3 and the tear-off blade 15 of the cutting knife 14 is moved into the cutting position shown in FIG. 3.
  • compressed air is first introduced into the cylinders 21 initiated and so the piston 22 biased.
  • a tilting movement of the holder 1 6 is not yet possible, since a lateral movement of the wheels 26 in the direction of the support roller 2 is prevented by the guide rails.
  • the piston-cylinder units 19, 20 move the tear-off blades 15 upward. As soon as the wheels 26 have left the air box 8 at the top, they are guided by the support roller 2.
  • the tear-off blade 15 when the tear-off blade 15 is moved upward, a tilting movement takes place in the direction of the supporting roller 1 without the piston-cylinder units 21, 22 having to be controlled.
  • the height of the support 18, the width of the holder 16 and the stroke of the pistons 22 are selected so that the tear-off blade 15 moves exactly into its separation position in the roller bed 3 with a short distance from the wrapped support roller 1 when the piston rods 19 are raised.
  • the full winding rolls 4 are then ejected via the non-looped support roller 2, the web 5 tearing off on the tear-off blade 15.
  • the new web start created in this way is held on the support roller 1, for example sucked onto it with a vacuum.
  • the tear-off blade 15 is then sunk again into the air box 8.
  • the piston-cylinder units 19, 20 move the support 18 with all the parts attached to it until the tear-off blade 15 is in the air box 8 is located.
  • the support rollers 1, 2 are rotated again and the winding is started again.
