Definitions

  • the invention relates to a roll cutting device for a material web with a material web feed section, a slitting section and a winding section, the at least one drive device for Has winding of at least one partial roll.
  • Such a roll cutting device is under the The name DuoRoller II from Voith Sulzer Paper Machines GmbH, Heidenheim, distributed (company publication “DuoRoller II - The winding concept for graphic papers”).
  • a roll winder with a web feed section and a winding section with at least one Drive device for winding a roll is off EP 0 736 474 A1 is known.
  • the invention is intended to be based on the example of a paper web are explained. But it is the same Can also be used with other material webs are handled in a similar manner.
  • Paper webs are commonly used in a paper machine made with a width that is larger than a width that is used in printing plants or other finishing plants can be handled. So can for example paper webs at the end of the paper machine have a width of the order of 10 m, while print shops typically have smaller widths, for example, 0.8 m to 3.8 m.
  • the paper web is divided into several longitudinal strips divided what the slitting section is used for, and wound up in a winding section.
  • the paper web can either be handled from a roll or directly from another processing station come, for example a calender.
  • the manufacture of the partial rolls is usually one the last steps before the paper roll is "finished", so handed over to processing companies becomes. After the partial rolls have been produced usually the packaging of the partial rolls.
  • the Packaging serves, among other things, to protect the roll from damage to protect.
  • the packaging is often done in that a packaging line around the circumference of the sub-roll, the packaging web applied in one or more layers can be.
  • the packaging line often axially over the end faces of the rollers.
  • the packaging is then used to help these end faces closed by so-called end covers, on which the The supernatant can be folded in.
  • the German utility master 1 854 746 describes a packaging device of fabric rolls that have a first changing bed with two driven by a common drive belt Has support rollers in which a roll of fabric is wound up becomes.
  • the back roller in the direction of travel forms together with another carrier roller, another winding bed, which has its own drive.
  • the finished wound fabric rolls can be used as a further changing bed be packed.
  • DE-OS 20 02 725 describes a method and a device for cross cutting, wrapping and banding long sections of paper or film material.
  • the material web is wound in a winding station, in which several rollers are arranged so that the winding roll to be wound in the circumferential direction surrounded different positions.
  • This changing station is via a transport route that consists of two in parallel band groups led to each other, with a Packing station connected.
  • the changing station is here arranged so that the winding roll when Keeps so that it does not stick with the tapes Conveyor belt groups come into contact.
  • the conveyor belt groups are controlled in terms of speed that the finished winding roll with decreasing speed is transported to the packing station but can no longer wind up here.
  • the invention is based, the cost to keep low.
  • This task is done with a slitter rewinder of the type mentioned solved in that in the winding section at least the scope of the sub-role packing packaging device is arranged, the the drive device for packaging the partial roll uses.
  • the packaging device preferably has at least a packaging web dispenser in parallel is movable to the winding axis. With the packaging web dispenser can then be added one after the other Pack the partial rolls. This is especially true of Advantage when processing partial rolls with changing widths become.
  • the partial roles can then on different axial positions can be arranged without that one has to take into account that there too Packaging lane must be present.
  • the packaging line is rather provided where the sub-role has been generated.
  • the packaging web dispenser to a position outside the sub-roll is movable.
  • the partial roles are usually sideways, i.e. across the winding axis, from the winding station pushed out. If you look at the packaging web dispenser for example so far laterally in the axial direction can move that it is outside the web width stands, then there is the possibility of side ejection receive. The packaging web dispenser is annoying not further.
  • the packaging web dispenser is preferably opposite the winding axis is pivotable and is also during manufacture the circumferential packaging parallel to the winding axis movable.
  • a peripheral packaging generated which is like a helix around the individual sub-roles.
  • This approach is currently in connection with a winder of considerable advantage. In such a Roll cutters are usually web rolls generated with changing widths.
  • you uses a packaging dispenser that has a creates helical packaging then you are no longer relying on the fact that a large number of Packaging lanes with the correct width for each Has available. You can have a single packaging line use with a fixed width.
  • This width can be relatively narrow. It is often sufficient if the Width is in the range of 30 to 80 cm. The necessary The axial length of the peripheral packaging then results automatically when producing the peripheral packaging. If an axially longer part roll is packed are flat correspondingly more revolutions of the partial roller necessary, to create the peripheral packaging.
  • the winding section advantageously has two winding position groups on, with the winding axes of the winding positions in a winding position group essentially are the same, the winding axes of both winding position groups are offset against each other and the partial roles in each of the two winding position groups are arranged to each other, for each winding position group a packaging web dispenser is provided. If you have a parent role or one upstream Processing device coming material web divided into several sub-roles, it is advantageous if you do not immediately see the individual sub-roles coiled next to each other, but separately. For this purpose it is known to have two (or more) winding positions to be provided whose winding axes do not match. If you now for each of these winding position groups its own packaging web dispenser then the packaging process can be accelerated. The packing times can be practically on be reduced by half.
  • the packaging web dispenser preferably has an adhesive mediator and a guide device on which the packaging web with its tackified Side of the sub-roll feeds. You can count on this Way to ensure that the packaging web on the circumference adheres to the part roll to be packed. If the part role then continues to rotate, then it pulls automatically their packaging web and wraps it on yourself at the same time. Here you can continue Apply glue. In many cases, however, it is enough even if the glue reappears at the end of the packaging process is applied. To make you sticky you can choose other options. So you can for example, use a packaging line that already coated with a water-soluble adhesive is, which then only needs to be moistened. Also Packaging webs coated with a hot melt adhesive are possible if the adhesive mediation device the corresponding supply of heat is guaranteed.
  • the guide device advantageously has one Guide path on the circumference of the sub-role in front of a Installation of the partial roll on a roller ends.
  • the packaging line can then be sent to the Extent of the sub-role to be performed on a Position where, when the reel turns, a short time later got into a gap between roller and roller.
  • There the packaging line is attached to the circumference of the partial roll pressed. This way you can be right achieve good adhesive results so that the packaging web is firmly glued to the circumference of the partial roll, at least at the beginning of the packaging process.
  • the guide path has a guide surface in which the distance of their End of the roller is changeable.
  • the packaging web it is often necessary that one the packaging web as close as possible to the circumference the sub-role brings. During the packaging process could interfere with the guide surface, however, in particular when the packaging web dispenser is being manufactured Move the peripheral packaging parallel to the axis becomes. If you pull back the end of the guide surface, thus the distance of the guide surface from the Partial roll or the roller enlarged, then the packaging process through the guide surface no longer with special needs.
  • the winding station is advantageous in the area of a machine frame arranged, and the packaging device is hung on the machine frame.
  • a machine frame is at many slitter winding stations available anyway. You can now take advantage of it Position packaging device.
  • the vertical position the packaging device is changeable.
  • Man can the packaging device for example lift when the packaged partial rolls are ejected should be.
  • the partial roll is preferably located during winding and packaging on two rollers.
  • a roller as Drive roller may be formed while the other only serves as a support or support roller.
  • the packaging line can be arranged with little effort between the roll to be packed and Insert one of the two rollers so that it immediately following the wrapping process, the peripheral packaging can be made.
  • the partial role rest on a roller with a roller core holding device is arranged above the roller.
  • the Roll core holding device is at the beginning of the winding process often pushed towards the roller, so that the roller can form a peripheral drive.
  • With increasing roll diameter increases weight the partial roll so that the roll core holding device only has to assume holding functions.
  • Even with one the circumferential packaging can be configured in this way easy to manufacture by having the packaging web into the gap between the roller and roller.
  • one spreader is arranged, and several Partial rolls are at a distance from each other in the winding device arranged, one between the Partially retractable knife device provided is.
  • the material web spread after cutting i.e. the individual tracks are guided so that they are in the winding device have a predetermined distance from each other.
  • the distance is usually a few centimeters.
  • you can then after finishing the Partial rolls a helical circumferential package the whole of the partial rolls. This is possible, because all sub-roles are usually the same Have diameter.
  • After making the peripheral packaging is then using the knife device a separation between the individual, packaged partial rolls made so that the partial roles again individually become manageable.
  • the knife device is preferably parallel movable to the winding axis. This also allows different Handle the widths of the partial rolls.
  • the Knife device is moved where there is a separation necessary is. Here you can separate the individual Carry out partial roles one after the other.
  • the Knife setup only needs one point of circumference can act. A circumferential cut is then made by rotating the roller.
  • a roll cutting device 1 has a feed section 2, in which a material web 3 of the device is fed.
  • the material web 3 can do this be handled by a jumbo or parent roll. But you can also directly from a calender or other post-processing facility. This is generally known and is therefore not explained further.
  • the material web 3 then runs through a slitting section 4, in which a cutting device 5 is arranged is.
  • the cutting device 5 divides the material web 3 in several lying side by side in the transverse direction Material web sections, the width of this Material web sections, also called partial webs to the needs of the customers of the material web is adjusted. If the original web of material 3, for example, a width in the range from 6 to 10 m has, then the partial webs have a width in the Of the order of 0.8 to 3.8 m.
  • the cutting devices 5 are adjustable in the transverse direction, so that different patterns can be created, the original material web 3 thus into several partial webs with different and changing widths can be divided.
  • a central roller 8 is provided in the winding section, which rotates in the direction of an arrow 9.
  • the central roller 8 is here from the material web 3 or whose partial webs are looped over a larger angular range.
