Definitions

  • the invention relates to a support roller winding machine according to the preamble of claim 1.
  • a support roller winding machine is known from DE-A-1 047 001.
  • Carrier roll winding machines of this type are used for the axleless winding of material webs divided by longitudinal section, in particular of paper or cardboard, onto sleeves, the winding rolls resting in alignment on the support rolls during winding.
  • axis reels in which a set of winding reels is held during winding by means of an axis that runs through all the sleeves, two guide heads are retracted from the outside into the sleeves of the outer winding reels during axleless reeling.
  • the winding hardness should be as uniform as possible for the entire set of winding rolls and across the diameter of each individual winding roll and have a predetermined value which, in the known carrier roll winding machines, is exceeded from a certain diameter onwards due to the increasing support weight and thus determines the maximum winding roll diameter.
  • the sealing elements shown in DE-PS 11 11 496 are not suitable for use on support roller winding machines with axleless reeling, since they and their fastening elements are in the range of motion of the guide heads.
  • the adjacent sealing roller creates a frictional connection between the two support rollers, which makes it no longer possible to set different torques to influence the winding quality.
  • the invention has for its object to provide a generic roller winding machine with axleless winding, with which winding rolls with a large diameter and high winding quality can be produced.
  • the support roller winding machine has the advantages of an axleless reeling (no cumbersome handling of a heavy and long axle, especially in the case of large web widths; rapid reel changes) without the maximum winding reel diameter being limited to the known extent by the support weight.
  • the relieving excess pressure also represents a further setting parameter by means of which the winding hardness can be controlled or regulated.
  • the lowerable sealing element according to claim 2 can be lowered by means of lifting or pivoting elements. On the one hand, this serves to remove the sealing element from the support rollers, e.g. B. to remove paper residue after a paper jam. On the other hand, it can be lowered to such an extent that end-side sealing elements arranged on the upper side of the sealing element - as claimed in claim 5 - are no longer in the range of motion of the guide heads.
  • separating knife Due to the pivoting of the sealing elements below into the area below a support roller according to claim 3, free space is created for a separating knife that can be raised from below through the support roller nip when changing rolls. Such separating knives can be used if the web is fed from below through the support roller nip.
  • Claim 4 contains an embodiment in which the end sealing elements can be moved axially from the area of the support rollers. The movement away from the area of the guide heads takes place either by a further axial movement outwards or by an additional lowering as soon as they have left the area of the support rollers.
  • the claims 5 to 8 contain embodiments of the invention, in which the front side sealing elements can be removed from the area of the guide heads by a swiveling movement.
  • the division according to claim 6 has the advantage that less space is required for the respective pivoting movement.
  • the sealing elements can already be used with a smaller winding diameter, in which the guide heads are located further down; ie the overpressure can already be used at an earlier winding point in order to influence the winding quality.
  • the embodiment according to claim 7 with circular guides attached to swivel arms, on which the end sealing elements are mounted, is structurally advantageous and space-saving.
  • a somewhat eccentric offset of the pivot axis to the support roller axes towards the outside in the claimed form has the effect that the sealing elements move somewhat away from the support rollers when pivoting.
  • paper scraps e.g. B. after a paper jam
  • the sealing elements are either attached to the inner end of the circular guides, which in this case are mounted so that they can be moved outwards in the swivel arms, or the swivel arms are angled, the apexes of the angles being outside the region of the support rollers.
  • Continuous round guides extending over the entire working width can then be attached to the swivel arms, to which the sealing elements are slidably attached.
  • the circular guides therefore do not need to be moved beyond the support rollers when set to the maximum web width (claim 8).
  • the sealing elements provided with labyrinth seals enable sealing without friction occurring with a winding roller or a support roller.
  • the sealing surfaces of the sealing elements having outlet openings for compressed air directed against the outflow direction, 11 the sealing effect can be increased by supplying sealing air.
  • Claim 12 contains an embodiment of the sealing surfaces with sealing elements that achieve high sealing effects with only low friction.
  • the particularly advantageous embodiment according to claims 13 to 16 enables lateral sealing with as little compressed air loss as possible at different overpressure values.
  • An equilibrium of forces between the contact pressure by the pneumatic piston-cylinder unit and the counterforce by the overpressure can be set so that a minimal gap between the sealing element and the end face of the outer winding roll is automatically set. If the gap decreases or increases due to an axial displacement of the winding roller, the overpressure rises or falls, so that the increased or reduced counterforce triggers a corrective movement of the sealing element.
  • the pneumatic piston-cylinder unit is structurally advantageous at the same time for the axial displacement of the sealing elements to adapt to different web widths.
  • an additional electric or hydraulic drive is provided for axial displacement.
  • the carrier roller winding machine for winding material webs enables the winding of winding rollers with a very large diameter, the regulation or control of the winding hardness being considerably simplified, since one of the decisive influencing variables, namely the line load on the two contact lines between the winding rollers and the Carrier rollers, no longer changed.
  • the double carrier roller winding machine has two carrier rollers 2, 3 mounted in the machine frame 1. These are arranged axially parallel with a small distance from each other and extend over the entire working width, ie the maximum width of the web 4.
  • the diameters of the support rollers 2, 3 are either different, then the axes of rotation are offset somewhat in height (FIGS. 1 to 3), or the diameters are the same, then the axes of rotation are in a horizontal plane (FIG. 4 until 10).
  • a longitudinal cutting device 5 is used to divide the material web 4 into individual webs, from which winding rolls 6 are produced, which lie flush with one another on the two support rollers 2, 3 during winding.
  • the web 4 is fed to the winding point either from below through the support roller nip (FIGS. 1, 4, 8) or from above, with a small wrap around a support roller (FIG. 6).
  • approximately vertical guides 7 are fastened in the frame 1 for a carriage 9 which can be moved up and down by means of a piston-cylinder unit 8 and which carries an inwardly projecting guide head 10.
  • the two guide heads 10 In order to guide the set of winding rollers 6 in the axial direction during winding, the two guide heads 10 each move from the outside into the two outer sleeves 11 before the start of winding and remain there until the winding rollers 6 are completely wound.
  • the guide heads 10 are fastened axially displaceably on the carriage 9 by means of a drive.
  • the carriage 9 carries a horizontally inwardly projecting hollow cylindrical guide, in which there is a pin which can be displaced axially by means of a spindle, to the end of which the guide head 10 is fastened.
  • a pin which can be displaced axially by means of a spindle, to the end of which the guide head 10 is fastened.
  • the guides 7 run outside the area of the upper gusset between the two support rollers 2, 3 at a distance parallel to the vertical on the connecting line between the two support roller axes through the center of the support roller gap. They end somewhat above the connecting line between the two carrier roller axes.
  • the guide heads 10 can thus move into sleeves 11 which are in the gusset between the two support rollers 2, 3. As soon as the lower edges of the slides 9 have moved sufficiently far upwards on the guides 7 with the sleeves 11 as the winding rollers 6 become larger, there is free space on both sides of the machine above the support rollers 2, 3 to prevent collisions with sealing elements described in more detail later avoid.
  • the machine has a reel ejection bar 12 and a lowering platform 13, which picks up the finished winding reels 6 and lowers them for unloading.
  • a separating knife 14 can be arranged below the support rollers 2, 3 for cutting the web 4, as shown in FIG. 6, through the support roller nip.
  • an air box 15 with a compressed air supply in all of the embodiments shown in the drawing, which extends at least over the area of the minimum width of the web 4 and has outlet openings on its upper boundary surface facing the winding rollers 6 for the compressed air.
  • the air box 15 is attached on its underside to lifting or pivoting elements so that it can be lowered. If underneath the support rollers 2, 3 a separating knife 14 which can be raised by the support roller nip is arranged, swivel arms 16 are attached to the air box 15, which allow pivoting down to below a support roller (support roller 3 in FIGS. 4 and 8) in order to provide space for starting up the Cutting knife 14 to create.
  • the air box 15 is lowered by means of lifting elements (lifting cylinder 17) (FIGS. 1, 6).
  • the side surfaces of the upper part of the air box 15 facing the support rollers 2, 3 are curved to match the surfaces of the support rollers 2, 3, only a small gap remaining in the sealing position to avoid friction.
  • the side surfaces On their sides facing the support rollers 2, 3, the side surfaces have a plurality of grooves which run parallel to the support roller axes and which act as a labyrinth seal extending transversely to the direction of flow of compressed air flowing out.
  • the height of the sealing side surfaces is adapted to the required sealing performance. It can be smaller on the side of the support roller 2, which moves into the upper gusset, than on the other side, because due to the direction of rotation with the support roller 2 or the web 4 located thereon, air which counteracts the outflow is carried along.
  • the upper side of the air box 15 simultaneously serves as a guide surface for two end sealing elements 18 which are axially displaceably fastened thereon on both sides of the machine.
  • the sealing elements 18 in the axial direction up to the area of the support rollers 2, 3 can be driven out, the air box 15 protrudes on both sides of the machine beyond the support rollers 2, 3, as shown in FIGS. 2 and 3.
  • the shape of the end sealing elements 18 is adapted to the free cross-sectional area between the support rollers 2, 3, the upper part being elongated in a rectangular shape up to above the connecting line between the two vertices of the support rollers 2, 3, to ensure a sufficient sealing surface for winding rollers 6 with a large diameter.
  • the extended part is provided on the side facing the end faces of the winding rollers 6 with grooves which sufficiently reduce compressed air losses in the manner described above as a labyrinth seal.
  • Grooves are also provided on the curved sides facing the support rollers 2, 3. They also run transversely to the possible outflow direction, that is to say approximately in accordance with the circumference of the respective adjacent support roller 2, 3.
  • the sealing elements 18 move laterally next to the guides 7, so that they can be moved against the end faces of the winding rollers 6, one in the sealing position small gap remains so that no friction occurs.
  • displacement elements for example a drivable spindle
  • the sealing elements 18 can be moved outwards so far that the carriages 9 with the guide heads 10 can be lowered into the gusset between the two support rollers 2, 3 in order to move into empty sleeves 11 lying there.
  • the air box 15 with the sealing elements 18 can be lowered so far that the upper edges of the sealing elements 18 are below the narrowest point between the two support rollers 2, 3.
  • the air box 15 thus only needs to extend to a lesser extent beyond the ends of the support rollers 2, 3.
  • the axial movement of the sealing elements 18 to the outermost ends of the air box 15 then only allow a subsequent lowering - either by pivoting or a linear lowering (FIG. 1) - which creates the space required for the slide 9.
  • the sealing elements 18 are connected on both sides of the machine with swivel arms 19, 20, the leg axes 21, 22 of which either coincide with the respective support roller axis or extend somewhat eccentrically outwards on the connecting line between the two support roller axes.
  • the low eccentricity means that the side surfaces of the sealing elements 18 facing the support rollers 2 or 3 move somewhat away from the respective support roller surface when swiveling out, in order to, for. B. To be able to remove paper residue. If it is necessary to move the sealing elements 18 further away from the support rollers, they are attached to double levers. Also in the embodiments according to FIGS. 4 to 7, the sides of the sealing elements 18 and the air box 15 facing the support rollers 2, 3 and the end faces of the winding rollers 6 are provided with the labyrinth seals described above.
  • the levers 19 pivotable about the outlet-side support roller 3 carry a one-piece sealing element 18 on each machine side.
  • the levers 19 are angled at their ends, so that they are in the pivoted-in position between the support rollers 2, 3 run approximately horizontally.
  • two round guides 23 are axially displaceably mounted, on the inner ends of which the sealing elements 18 are fastened.
  • each end sealing element 18 is subdivided along the vertical through the center of the support roller nip.
  • Each of the parts 24, 25 is fastened to a swivel arm 19, 20 which can be swiveled over the adjacent support roller 2, 3. The pivoting movement thus requires less space, as shown in FIG. 6, so that the sealing element 18 can be used at an earlier point in time.
  • the sealing elements 18 are mounted axially - that is to say transversely to the web 4 - on levers 19 pivotable about the outlet-side support roller 3. They can thus be moved out of the lower working area of the guide heads 10 by swiveling over the support roller 3 (shown in broken lines in FIG. 8).
  • the swivel levers 19 are angled at their free ends so that they extend approximately horizontally in the swiveled-in position between the support rollers 2, 3. Its pivot axis 25 runs somewhat eccentrically outwards on the connecting line between the two carrier roller axes.

  • the piston-cylinder unit 26, 27 is used both for the axial displacement of the sealing elements 18 for adaptation to different web widths and for pressing against the winding rollers 6. It is also possible to perform these two tasks by separate drives. An electrical or hydraulic drive for axial displacement is then attached to the swivel levers 19 and is connected to the sealing elements 18 via the pneumatic piston-cylinder units 26, 27.
  • the swivel arms carrying the sealing elements 18 are angled, the apexes of the angles being outside the region of the support rollers 2, 3. At the apexes of the angles, the ends of guides extending over the entire length of the support rollers 2, 3 are fastened, on which the sealing elements 18 are slidably mounted. The guides are therefore no longer moved in the axial direction for adjustment to different web widths.
  • the pressure roller 26 is additionally pressed in the direction of the support rollers 2, 3.
  • an excess pressure is generated in the space delimited by the support rollers 2, 3 and the winding rollers 6 by introducing compressed air, which reduces the support weight.
