Description
- The invention relates to a reel-up for reeling up a fibre web continuously around a reel spool into a machine reel, which reel-up comprises:
- a reeling drum for forming a nip with the machine reel being reeled up,
- a frame which is arranged for supporting the machine reel and which frame is connected with a roller rail along which the reel spool operating as the core of the machine reel is transferrable in the x direction by rolling the bearing housings of the reel spool,
- in which reel-up the fibre web is reelable up oscillatingly into the machine reel.
- The reel-up is a device which reels a material produced as a continuous fibrous web into the reel form as a machine reel. In the production process of the fibre web, reeling-up is usually the first subprocess in which continuous production is interrupted to continue in sequences. The machine reel is formed around the reel spool operating as the reeling core i.e. the fibrous web being on one machine reel has a start and an end. The trend in the field is a continuous increase in the size of machine reels, which causes an on-going development requirement for reel-ups. The dimensioning of the reel spool specifies the maximum size of the machine reel in practice. However, as we are concerned with a dynamic environment and the fibre web is reelable material sensitive to various faults, the task performed by the reel-up as the maintainer of the efficiency of the paper or board machine is very considerable. A reason behind the continuous increase in the size of machine reels is the desire to obtain fewer starts and ends in the production of the fibrous web, which impede or disturb the production and decrease the efficiency.
- At its time, the method described in patent
FI91383 EP0483092B1 ) transferred the size of the machine reels to a new order when it was possible to build the beginning of the machine reel in a good way from the viewpoint of the properties of the fibre web being reeled. The importance of the beginning is emphasised when the quantity of the fibre web being reeled is increased, because the beginning operates as the "basis" of the reel structure. Here, a feature developing the technology was the progressive centre torque of the machine reel provided by means of primary and secondary centre drives, which enabled the use of versatile reeling parameters in building the machine reel. The prior art preceding this arrangement was the so-called Pope reeler in which the machine reel was built by pressing the machine reel against the driving reeling drum, whereby the machine reel was formed by means of friction between the reeling drum and the machine reel. - The method described in patent
US5370327 for the first time introduced an idea of building a machine reel on one vertical plane such that the machine reel is on top of horizontal rails on the same vertical height throughout reeling.FI91383 US5370327 , the moving reeling drum enables the centre of the reel spool remaining on a constant plane. An advantage of this arrangement is the shifting of the adjustment of nip force from loading occurring on the side of the machine reel to loading occurring on the side of the reeling drum of constant mass. - In addition to the above-described "pioneering patents" for second-generation reel-ups, there is a wide variety of different embodiments which have further developed the principles depicted in these two patents. One of those is
patent US6354531 which describes many different alternatives in arranging the fibre web into the machine reel oscillatingly. SpecificationWO2007/010094A2 also describes some possible arrangements for reeling up the fibre web oscillatingly.WO 02/34 655 A1 - In a continuous reel-up on the market, oscillation in secondary reeling occurs by deflecting the machine reel and the reeling drum in the machine direction, i.e. the fibre web is turned. This is described in more detail in specification
DE19939506 . This arrangement requires a movable reeling drum and can thus affect the tension profile of the coming fibre web. - In the applicant's continuous reel-up marketed by the name of OptiReel Plus, the machine reel is oscillated in the cross direction during secondary reeling such that parent-roll sledges moving the machine reel in the x direction and supporting the load are also moved in the y direction.
- In the context of describing this invention, the following terms are used to facilitate the description: machine direction (MD) is referred to as the x direction, cross direction (CD) is referred to as the y direction and elevation is referred to as the z direction. The incoming direction of the fibrous web is referred to as the upstream direction and the outgoing direction of the fibrous web is referred to as the downstream direction. A reeling core is referred to in this context as a reel spool, but it could be called a reeling shaft as well.
- An object of the invention is to develop an arrangement which enables a simple and reliable reel-up by means of which it is possible to reel up the fibre web osciallatingly when desired. An object of the invention is also to provide an arrangement the reeling principle of which is based on a known way to form the machine reel by means of the reeling drum.
- It is characteristic of the reel-up according to the invention that the roller rail is arranged movable in the y direction in relation to the frame for providing an oscillating path of the reel spool.
- Thus, the cross-directional oscillation of the machine reel is managed by moving the roller rail of the reel spool in the cross direction the machine reel following along. Below the roller rail are arranged bearing parts in which sliding surfaces sensitively slide against each other, being low frictional. Advantageously for this, between the roller rail and the frame is arranged a planar slide bearing to support the load caused by the mass of the machine reel.
- In specific embodiments, the roller rail is connected to an auxiliary frame, which has a higher moment of inertia than the roller rail at least in the z and y directions, between which auxiliary frame and the frame is arranged the planar slide bearing to support the load caused by the mass of the machine reel. Furthermore in an arrangement according to an advantageous embodiment, as an element controlling the motion of the rail between the roller rail or the auxiliary frame and the frame is arranged a controlling guide to control the motion of the roller rail in the y direction.
- The sufficient oscillation of the machine reel diminishes faults which narrow trails of the fibre web can cause to reeling-up or the structure of the machine reel. These include the exit of air occurring from the ends of the machine reel becoming difficult or prevented, stretch streaks formed in the machine reel of the fibre web and other equivalent problems. These possible problems increase as the diameter of the machine reel increases, i.e. the effect is recurring. Generally oscillation, in which the fibre web is deflected in the y direction during reeling-up from one edge to the other with the measure from a few centimetres to about ten centimetres, is sufficient to obliterate the problems caused by streakiness. It is also important to set an oscillation length of the fibre web suitable in order for the fibre web not to stretch unnecessarily as a result of oscillation. Oscillation length Losk = v* tosk where v is production speed and tosk is time in which one reciprocating oscillation motion is done. For example, the duration of the oscillation cycle being one and a half minutes and the production speed of the fibre web being 1,800 m/min, the oscillation length is 2,700 metres which is sufficient in most cases.
- The invention will now be described in more detail with reference to the accompanying figures, in which figures:
-
Fig. 1 shows a first embodiment of the invention, -
Fig: 2 shows a second embodiment of the invention. - Embodiment 1: The embodiment shown in
Fig. 1 presents a structure in which between aroller rail 23 and aframe 20 is anauxiliary frame 21 by means of which sufficient load bearing capacity and rigidity are ensured in both the z direction and the y direction. A particularly intended property of thisauxiliary frame 21 is its sufficient rigidity in the z direction. Then, the load caused by the mass of amachine reel 6 is divided in the x direction (and y direction) into an adequately large area on a planar bearingsurface 25. An oscillation motion is implemented withactuators 30 of which there are sufficiently many on the distance of the roller rail to provide a required oscillation force. To ensure the straightness of the roller rail for the whole length of the roller rail, the auxiliary frame also ensures rigidity in the y direction. To ensure rigidity, the term of moment of inertia is the most descriptive parameter directly calculatable from geometry. -
Fig. 1 shows an embodiment of the oscillation mechanism of the roller rail and its bearing. The figure shows a bearinghousing 58 of the reel spool which rolls as the reeling-up proceeds along theroller rail 23 in the x direction. Theactual roller rail 23 is fastened to theauxiliary frame 21. Between theauxiliary frame 21 and theframe 20 is arranged the sufficiently sensitive planar slide bearing 25 which supports the load caused by the machine reel (in the z direction) and enables the y-directional motion. The mass of the machine reel can be just before the change up to 200,000 kg, whereby the load of one end of thereel spool 5 becomes 100,000 kg. The mass of themachine reel 6 comprises both the mass of the fibre web W reeled into the machine reel and the mass of thereel spool 5. This load caused by the total mass is conveyed to be supported by theframes 20 such that, around ashaft 52 rotating as one piece with amantle 51 of the reel spool at the end area of thereel spool 5, there is a sleeve-like bearinghousing 58 bearing-mounted rotatable via which the load transfers to theroller rails 23. At the end of the reel spool, there is acoupler 59 within which the coupler of thedrive 8 stays in the same position in the y direction during oscillation, whereby apower transmission shaft 80 of thedrive 8 is variable of its length. - When oscillating the
machine reel 6, the mass of the machine reel causes a friction force of a cross-directional motion which is Fµ = M*g*µ where M is mass, g is gravitational acceleration and µ is the friction coefficient between the surfaces. As the sliding surface, it is possible to use e.g. RIMET by Oy Johnson Metall Ab the friction coefficient µ of which in such an embodiment is about 0.07. A planar slide bearing 25 suitable for the purpose includes a steel body and material comprising teflon-lead mixture as the sliding surface. As a tabular value for such a bearing has been presented e.g. the maximum surface pressure of 80 MPa which must be considered when designing the dimensions of the slide bearing. Furthermore, the planar slide bearing 25 can comprise several separate bearing elements which can be most advantageously arranged x-directionally successively. The planar slide bearing 25 can be permanently lubricated or lubricated by means of feedable lubricant. - Embodiment 2: The embodiment shown in
Fig. 2 does not include an auxiliary frame between theroller rail 21 and theframe 20 but directly theplanar slide bearing 25. This application is very usable at targets in which the masses of themachine reel 6 are small by modern standards, whereby the rigidity of the actual roller rail is sufficient. In other respects, the parts of the construction are equivalent to the components shown inFig. 1 and to their numbering as well as above-described properties and alternatives. - Furthermore in an arrangement according to an advantageous embodiment related to both embodiment 1 and embodiment 2, as an element controlling the motion of the
roller rail 23 between theroller rail 23 or theauxiliary frame 21 and theframe 20 is arranged a controllingguide 26 to control the y-directional motion of theroller rail 23. Advantageously, the controllingguide 26 is arranged not supporting z-directional load, whereby all z-directional load can be applied to be supported by theplanar slide bearings 25. - Additionally in an arrangement according to an embodiment, the cross-directional motion is done by means of eccentric wheels. The rotation of the oscillation shaft can be implemented e.g. with an electric motor + gear combination. The constant oscillation motion can be implemented by rotating in one direction and smaller than the maximum quantity by a reciprocating motion. Alternatively, the eccentrics can be replaced by a lever mechanism. An
actuator 30 providing the y-directional motion of theroller rail 23 can thus comprise an eccentric, a lever mechanism or other equivalent arrangement providing a reciprocating motion. The total force produced by theactuators 30 must exceed the earlier-mentioned friction force Fµ in order for the oscillation to operate. - Advantageously, the tending and driving sides of the reel-up have their
own actuators 30 which are electrically synchronised with each other. The coupler of thedrive 8 of thereel spool 5 is oscillated in the same phase as the roller rails. - In other respects, the reel-up can employ known or otherwise suitable construction arrangements of reel-ups. For example, primary reeling can be done with a known traditional turning method or supported by rails, whereby the reeling drum gives way downwards when the machine reel being formed during primary reeling is transferred forward in the x direction.
- As evident to those skilled in the art, the invention and its embodiments are not limited to the above-described embodiment examples. Expressions representing the existence of characteristics, such as "the frame is connected with a roller rail", are unlimited such that the description of characteristics does not exclude the existence of such other characteristics which are not presented in the independent or dependent claims.
