Definitions
- Winding machine for winding a material web, in particular a paper or cardboard web, into winding rolls
- the invention relates to a winding machine for winding a material web, in particular a paper or cardboard web, to winding rollers with two support rollers, which form a winding bed in which the winding rollers rest during winding and to which the web is fed from below through the gap between the two support rollers ,
- Such winding machines are known to be used to wind a paper or cardboard web divided by longitudinal cuts into winding rolls.
- the winding rolls are lined up axially aligned next to each other on the two support rollers, which thus support the entire weight of the winding rolls.
- the web is fed to the winding bed either from below through the gap between the two support rollers, or from above via one of the two support rollers.
- the winding hardness should be as uniform as possible over the diameter of each individual winding roll and should not exceed a predetermined value. Since the line load increases with increasing winding roll diameter, carrier roll winding machines can only produce winding rolls with the required winding quality up to a certain diameter with no means to relieve the winding roll weight.
- EP 0 442 038-B1 discloses a generic roller winding machine in which the web is fed to the winding bed from below through the gap between the rollers.
- the winding machine contains an ejection roller which can be pivoted about a support roller.
- the ejection roller is freely rotatable on lateral swivel arms which can be pivoted about the axis of the support roller.
- the invention has for its object to provide a support roller winding machine of the generic type with which winding rolls with a large diameter and high winding quality can be produced with high operational reliability.
- an additional roller which can be swiveled up in the direction of the roller bed is arranged on the outside of each support roller, each additional roller extending parallel to the support rollers over their length and each being mounted at the free end of two pivot levers which are parallel about an axis to the support roller axis, preferably about the adjacent support roller axis itself, and which protrude radially with a part of the respective support roller, the length of which is less than the maximum radius of a completely wound winding roll.
- the two additional rollers can be swiveled in as additional support rollers when the winding roll has reached a certain diameter. They then take over part of the roll weight, with the result that the bearing weight of the winding rolls is borne by four rolls. This reduces the line load on the two support rollers and thus the winding hardness in the winding roll.
- the two support rollers can also be designed in a structurally simpler manner with a smaller diameter.
- an air box can be hung in the area between the support roller and the associated additional roller between the two pivoting levers, which has openings towards the winding roller and is connected to a compressed air supply. In this way, an overpressure can be generated on each side below the winding roll in order to reduce the bearing weight.
- Carrier roller and respective additional roller then also serve as sealing rollers which seal the air box against the winding roller.
- the two additional rollers prevent the winding rolls from jumping out of the winding bed when they are being wound up.
- profile fluctuations in the web can lead to increasing vibrations of the winding rolls, which in extreme cases can lead to a so-called roll ejection.
- the additional rollers keep the winding rolls in the changing bed.
- they can be connected to damping elements that counteract the vibrations and thus prevent the winding rollers from rocking.
- the two additional rollers with their swivel levers can also be used advantageously as components of a winding roll changing device.
- the additional roller on one side serves as an ejection roller, with which a set of completely wound winding rollers is pushed out of the winding bed over the other support roller.
- the second additional roller with its swivel levers which can therefore also be used as a lowering platform to lower the winding rolls onto the corridor area. There they are transported away by a floor conveyor.
- Figure 1 shows schematically the side view of a winding machine according to the invention.
- Figure 2 shows an enlarged area between a support roller and the additional roller with an air box.
- Figure 3 shows a section through the air box.
- Figure 6 shows the function of the additional rollers as a protective device.
- Figure 7 shows the function as an ejection and lowering device when changing roles
- the carrier roll winding machine shown in the figures is used to wind a paper or cardboard web divided by longitudinal cuts into winding rolls.
- the up to 10 m wide paper or cardboard web is drawn off from a supply roll by a roll-off device, not shown, divided by longitudinal cuts and then wound on sleeves 1.
- the support roller winding machine contains two support rollers 2, 3, which are arranged parallel to one another at a small distance and are each connected to a rotary drive 4, 5.
- the two support rollers 2, 3 extend over the entire working width of the winding machine, ie the maximum width of the web to be wound up. They consist of a cylindrical roller body made of steel with shaft journals on the end faces, with which they are mounted in the frame 6 of the winding machine and on which the rotary drives 4, 5 act. Their diameter is 350 mm to 1500 mm, preferably 500 mm to 950 mm, with an axial length of up to 10 m.
- a limitedly deformable running layer is preferably applied to the outer lateral surface in order to improve the winding quality.
- a wear-resistant elastomer with a hardness between 65 and 80 measured according to Shore A is advantageously used for the overlay, as described in EP 0679595-A1.
- the thickness of the overlay is then 5 mm to 12 mm.
- An advantageous alternative consists in producing the deformable running layer from a cellular plastic material with a multiplicity of uniformly distributed pores, as described in EPO 879 199-B1.
- the pore size is then less than 5 mm, preferably between 0.05 mm and 1 mm, and the compression modulus K of the material is less than 10 MPa. This material is volume compressible, so that no lateral beads form when a winding roll is pressed into the deformable layer.
- the two support rollers 2, 3 form a winding bed, in which the winding rollers 6 rest during winding.
- the web 7, divided by longitudinal cuts, is fed to the winding bed from below through the gap between the two support rollers 2, 3.
- a pressure roller 12 which extends over the entire working width, can be raised and lowered in the frame of the winding machine.
- each support roller 2, 3 there is an additional roller 8, 9 which can be swiveled up in the direction of the roller bed.
- Each additional roller 8, 9 extends parallel to the support rollers 2, 3 over their length and is in each case freely rotatably mounted at the free end of two pivot levers 10, 11.
- the second pivot lever of an additional roller 8, 9 is located on the other side of the machine.
- the two pivot levers 10, 11 can be pivoted about an axis parallel to the axis of the support roller 2, 3, preferably about the respective support roller axis itself, as shown in FIG. 1.
- the two additional rollers 8, 9 can thus be moved towards one another and towards the roller bed from the outside.
- Each of the swivel levers 10, 11 projects with a part beyond the respective support roller 2, 3, the length of which is less than the maximum radius of a fully wound winding roller 6.
- the two additional rollers 8, 9 protrude Apply a certain winding roll diameter to the winding roll 6 at a height below the winding tube 1.
- the two additional rollers 8, 9, like the support rollers 2, 3, are constructed from a roller body made of steel, which has a shaft journal on each end face, which is each supported in a pivot lever 10, 11. Their diameter is preferably slightly smaller than the diameter of the support rollers 2, 3.
- the additional rolls - as in the present case - are also used as sealing rolls, they have a running layer made of the cellular and thus volume-compressible plastic material described above for the support rolls 2, 3.
- the thickness of the overlay is 2% to 15% of the roll diameter.
- the additional rolls 8, 9 are provided with damping elements, by which the vibrations of the winding rolls 6 are damped.
- damping elements friction dampers or active damping elements are either integrated into the mounting of the additional rollers 8, 9 on the pivot levers 10, 11 or connected to the pivot levers 10, 11.
- An air box 13, 14, which has openings to the winding roller 6 and is connected to a compressed air supply, can advantageously be suspended between the two pivot levers 10, 11 of each additional roller 8, 9. It can be generated on each side below the winding roller 6, an excess pressure to reduce the weight.
- each air box 13, 14 is connected to a compressed air blower 16 via a supply line 15.
- the pressure in each air box 13, 14 can be adjusted with control flaps 17 which are arranged in the respective supply line 15.
- FIGS. 2 and 3 The structure of an air chamber 13 is shown in more detail in FIGS. 2 and 3:
- the air chambers 13, 14 are each suspended between the pivot levers 11, 12 in the area between a support roller 2, 3 and the additional roller 8, 9 so that only a small gap between the air box 13, 14 and the respective support roller 2, 3 and respective additional roller 8, 9 remains.
- the additional rollers 8, 9 serve as sealing rollers which seal the pressure space below the winding roller 6 in the circumferential direction of the winding roller 6.
- the boundary wall 18 of an air box 13, 14 facing the winding rollers 6 has a plurality of openings 19 through which the compressed air can exit in the direction of the winding roller 6: the supply line 15 is connected to the rear wall 20 of the air box 13, 14.
- the two air boxes 13, 14 are divided into individual, separately switchable chambers 20 in the area of the possible positions of the longitudinal edges of the web 7, which are transverse to Extend the direction of web 7.
- Each chamber 20 is, on the one hand, by one that extends across the working width
- the rear wall 21 has an opening 23 for each chamber 20, which can be closed and opened in each case by means of a slide 24.
- Each slide 24 is actuated by a piston-cylinder unit 25 which are arranged in the common feed chamber 22.
- Each air box 13, 14 is preferably divided into individual chambers 20 at its two lateral end regions, each of which has a width of approximately 150 mm measured in the axial direction of the rollers 3, 9.
- the number of chambers 20 is determined as a function of the difference between the maximum and minimum width of a web 7 to be wound so that the lateral areas of the air boxes 13, 14 outside the web 7 can be closed so that there are no unacceptable compressed air losses.
- FIGS. 4 and 5 show possibilities for sealing the pressure space on the end faces of the winding rolls 6.
- Each air box 13, 14 thus has a sealing plate 26 on each machine longitudinal side, which seals the lateral opening between the air box 13, 14, the support rollers 2, 3, the additional rollers 8, 9 and the outer end face of the winding roll 6.
- the sealing seals 26 are adapted on their underside to the shape of the boundary wall 18 of the air box 13, 14, and at their lower lateral ends to the shape of the rollers 3, 9. They have a part which extends into the region of a winding roller 6 and which seals against the end face of the winding roller 6.
- the sealing plates 26 are preferably positioned together with the edge knives of the upstream longitudinal cutting device. The edge knives cut the two longitudinal edges of the web 7. These two longitudinal cuts lie exactly in the transverse position in which the sealing plates 26 have to be positioned.
- FIG. 4 shows a particularly advantageous embodiment of a sealing plate 26.
- the sealing plate 26 is circular and is pushed transversely to the web 7 into its working position by means of a spindle drive 27.
- FIG. 6 shows the function of the pivot levers 10, 11 with the two additional rollers 8, 9 as a protective device against undesired roll ejection.
- the length of the swivel levers 10, 9 is chosen to be large enough that the angle a between the connecting lines of the two additional rollers 8, 9 and the winding tube 1 is sufficiently large even at the maximum winding roller diameter.
- the angle a is preferably more than 90 °.
- the winding rolls 6 are held in their position in the region of the circumferential angle a by support elements.
- the additional rollers 8, 9 can be connected to damping elements which counteract vibrations of the winding rollers 6 and thus prevent the winding rollers from rocking.
- FIG. 7 shows an embodiment in which the swivel arms 10, 11 with the additional rollers 8, 9 are advantageously used as parts of a winding roll changing device:
- the additional roller 8 on the web entry side - on the left in FIG. 7 - also serves as an ejection roller, with which completely wound winding rollers 6 are pushed out of the winding bed via the second support roller 3.
- the winding rollers 6 roll over the second support roller 3 onto the second additional roller 9, which is lowered to such an extent that the winding rollers 6 are received in a bed formed by the second support roller 3 and the additional roller 9.
- the second additional roller 9 is then lowered further until the winding rollers 6 are at the floor level. There they are transported in a known manner by floor conveyors.
- the second additional roll 9 on the web exit side with its pivot levers 11 thus also takes on a task for which a separate lowering device is required in known carrier roll winding machines.
- the carrier roll winding machine is operated in a known manner without relieving the weight of the winding roll.
- the swivel arms 10, 11 with the additional rollers 8, 9 are swiveled and out of function.
- the pressure roller 12 lies on top of the winding rollers 6 and increases the bearing weight of the winding rollers 6 on the support rollers 2, 3 as long as the dead weight of the winding rollers 6 is not yet sufficient. With increasing winding roll weight, the contact force of the pressure roller 12 is reduced accordingly to the value 0.
- the weight of the winding reel finally becomes so great that, in order to avoid an undesirably high winding hardness, the support weight on the support rollers 2, 3 must be reduced.
- the swivel arms 10, 11 are pivoted up with the additional rollers 8, 9 until the additional rollers 8, 9 rest on the winding rollers 6 (FIG. 9).
- the side sealing plates 26 are moved against the end faces of the outer winding rollers 6, so that in each case the space between a support roller 2, 3, the associated additional roller 8, 9 and the winding roller 6 is closed in a pressure-tight manner.
- the support roller winding machine has the great advantage that when the swivel arms 10, 11 are lowered, the effective relief surface 28 is permanently enlarged. With constant overpressure, the relief force increases as a product of the relief area and the overpressure. The automatically resulting enlargement of the relief surface automatically leads to an increased relief force, which is necessary to compensate for the increasing winding roll weight, while the overpressure remains the same. It is therefore only necessary to reduce the air pressure to keep the line load on the support lines of the winding rollers 6 on the support rollers 2, 3 constant.
