Definitions

  • the invention relates to manufacturing lines of a fibre web, such as a paper web, more particularly to slitting and winding.
  • the invention relates to a fibre-web manufacturing line according to the preamble of claim 1.
  • the invention also relates to a slitter-winder according to the preamble of claim 15.
  • paper is manufactured in machines which together constitute a paper-manufacturing line which can be hundreds of metres long.
  • Modern paper machines can produce more than 450,000 tons of paper a year.
  • the speed of the paper machine can exceed 2,000 m/min (120 km/h) and the width of the paper web can be more than 11 m.
  • paper making takes place as a continuous process.
  • a paper web completing in a paper machine is wound with a winder around a winding shaft i.e. a reel spool into a machine roll the diameter of which can be more than 3.5 m and the weight of which more than 100 tons.
  • the purpose of winding is to modify the paper web manufactured as planar into a more easily processable form.
  • the continuous process of the paper machine breaks for the first time and shifts into periodic operation. This periodicity is tried to be made with efficiency as good as possible in order to not to waste already done work.
  • the machine-roll web produced in paper-making is full-width and even more than 100 km long so it must be slit into partial webs with suitable width and length for the customers of the paper mill and to be wound around cores into so-called customer rolls before delivering from the paper mill.
  • These slitting and winding take place as known from prior art in an appropriate separate machine i.e. in a slitter- winder.
  • the machine roll is unwound, the wide web is slit on the slitting section into several narrower partial webs which are wound up on the winding section around winding cores, such as spools, into customer rolls.
  • winding cores such as spools
  • customer rolls are completed, the slitter- winder is stopped and the rolls i.e. the so-called set is removed from the machine after which the process is continued with the winding of a new set.
  • These stages are repeated periodically until paper runs out of the machine roll, whereby a machine roll change is performed and the operation starts again as the winding of a new machine roll.
  • the paper machine can produce more paper than a single slitter-winder is able to process, whereby the line requires several slitter- winders which are normally located in the direction of the machine line and side by side at a certain distance from each other. Many times into the space between them is located a control room of the machines or a corresponding arrangement.
  • the first slitter-winder is usually arranged as a so-called inline slitter- winder, which means that it is located in line with the paper machine i.e. in the principal machine line.
  • the second slitter-winder is a so-called offline slitter-winder i.e. it is not located in the centre line of the paper machine but normally beside the first slitter-winder, in its own so- called aisle i.e. in an extension section of the machine room built for it.
  • Both slitter-winders produce customer rolls which are transported by roll conveyors first e.g. to the roll packaging machine to be packed and finally to the storage before delivering to the customers.
  • a machine roll is normally brought with a hoist and lowered onto transfer rails which are typically located so that the height of the centre of the machine roll from the floor level is about 2.5 m.
  • the machine roll is transferred along the transfer rails from the winder to the slitter- winder.
  • a machine roll carriage brings a machine roll at the end of the transfer rails and transfers the machine roll onto the transfer rails.
  • the prior-art transfer rails of full machine rolls consist of horizontal or inclined rails with their stand-by stations.
  • On the transfer rails there are normally one or more rail gates which enable the operator to access the machine rolls.
  • On the transfer rails the machine roll is transferred from one stand-by station to another until an unwinding station.
  • On horizontal transfer rails the transfer is done by means of a transfer device and, on inclined transfer rails, by means of gravity by allowing the machine roll to roll along the inclined transfer rails, whereby the stand-by stations are provided with mechanisms by means of which the machine roll is stopped and released towards the unwinding station.
  • the unwinding station typically consists of two unwind stands which carry the machine roll during unwinding. Locking arms are pivoted in the unwind stands by means of which the machine roll is locked in place for the time of unwinding.
  • the machine roll at the unwinding station is coupled to a brake generator which operates as the actuator of the unwinder.
  • the emptied reel spool i.e. winding shaft is removed from the unwinding station either manually by lifting with a hoist or automatically by means of a handling apparatus of the reel spool.
  • the handling apparatus of the reel spool consists either of vertical lifting devices or turning lifting arms and upper return rails of empty reel spools. An empty or nearly empty reel spool is lifted with the lifting device or with the lifting arms onto return rails on which there are normally several return station points.
  • the return station spool storage
  • the return station spool storage
  • the reel spool On the return rails, the reel spool is transferred from one station to another either by means of the transfer device or by means of gravity by rolling by means of the stopping and releasing mechanisms. From the return rails, the empty reel spool is removed and transferred onto the winder of the paper machine by the hoist or the machine-roll carriage.
  • the return rails can also be coupled directly to the storage rails of the reel spools of the winder, whereby the reel spool can be directly transferred from the slitter-winder onto the winder.
  • the lifting devices of the reel spools are dimensioned so that only a little paper can be on the reel spool, whereby in situations in which a reel spool on which there is still a lot of paper or possibly a whole machine roll ends up as broke, the unloading of the roll has been had to perform at the unwinding station, whereby the time used for unloading is absent from the production capacity.
  • unloading performed on the return rails has caused faults in the reel spool traffic.
  • An object of the invention is to provide a slitter- winder layout in which the above- described problems and disadvantages have been eliminated or at least minimised.
  • an object of the invention is to create a slitter- winder layout which is cheap of its costs.
  • a particular object of the invention is, for the part of use of space, to utilise more effectively than earlier basement facilities below the paper machine room which exist or which are otherwise required in any case.
  • the utilisation rate of these basement facilities has been comparatively low.
  • An object of the present invention is thus to provide a novel space arrangement for a slitter-winder of a paper machine in which said basement facilities can be utilised more effectively than earlier.
  • an object of the invention is to provide such a space arrangement for a slitter-winder of a paper machine room in which the other space requirements of the paper machine room can be decreased and the space arrangements of the paper mill can be diversified.
  • reel spool is used for describing winding shafts and equivalents around which the machine roll is wound and from which the machine roll is unwound before slitting.
  • the slitting and winding section of the slitter-winder can be constituted of one apparatus unit which comprises both a slitting section and a winding section, and that the slitting and winding section can be constituted of two separate apparatus units of which one comprises a slitting section and the other a winding section.
  • a slitter-winder according to the invention is principally characterised by what is presented in the characterising part of claim 15.
  • the arrangement according to the invention provides a totally new layout arrangement of a slitter-winder of a paper mill in which transits and transfers can be constituted by following a totally novel way of thinking.
  • the invention enables a manufacturing line of a fibre web in which the whole fibre- web machine is in one principal line, whereby the so-called aisle is no longer required.
  • the unwinding of the slitter-winder of the fibre-web manufacturing line is located on the machine room level i.e. machine level and at least one slitting and winding section is located below the machine room level, advantageously in the so-called basement facilities.
  • the unwinding is located on the machine room level so that the transfer of machine rolls and reel spools in the different stages of processing remains substantially in the same vertical zone which extends from the floor level of the machine room to a height in which the height of the central axis of the reel spool does not substantially exceed the maximum height of the full machine rolls at the unwinding stations.
  • the slitter- winders are located in the machine line substantially successively so that their unwinders are on the machine level and the slitting and winding sections of at least one are downstairs.
  • the paper-manufacturing line comprising two slitter-winders, the slitting and winding sections of both slitter-winders are downstairs. Then, a considerable amount is saved in building costs when it is not necessary to build an expensive separate aisle. Furthermore, cost savings are attainable in transfer device costs, e.g. for the part of a second hoist, a machine-roll transfer carriage and a pulper.
  • the slitter-winders are located successively and advantageously so that the transfer of machine rolls takes place along one pair of transfer rails, whereby the full machine rolls are easily transferrable and the machine- roll traffic flows.
  • the bottom-end broke can advantageously be conveyed into a shared pulper arranged between the unwinding stations.
  • the transfer rails of the machine roll are of the so-called through-winding type i.e. the unwinding station is also through-winding, whereby the handling of machine rolls is straightforward and simple. Then, there is no need for a machine-roll carriage for transferring the machine roll, which further increases cost-savings.
  • the transfer rails of the machine roll can be located directly on top of floor joists so that between the rails and the floor level there are no e.g. footings or corresponding support and raising structures, whereby the structure is obtained flat and great masses as low as possible. A required/possible floor level in the area between the transfer rails can be located lower than the actual machine level.
  • the handling devices of the rolls are located downstairs.
