Definitions

  • present invention relates to producing fiber web in a fiber web machine. More especially the present invention relates to an arrangement according to preamble part of claim 1.
  • a typical production and treatment line comprises a head box, a wire section and a press section as well as a subsequent drying section and a reel-up.
  • the production and treatment line can further comprise, for example, a calender.
  • the production and treatment line also typically comprises at least one slitter-winder for forming customer rolls as well as a roll packaging apparatus.
  • fiber webs such as paper or board webs
  • fiber web manufacturing line which may be hundreds of meters long.
  • Modern paper machines may produce more than 450,000 tons of paper per year.
  • the speed of a paper machine may exceed 2000 m/min and the width of a paper web may be more than 11 meters.
  • manufacturing operates as a continuous process.
  • the finished fiber web being output from the machine is wound with a reel-up around a reeling shaft, i.e., a reel spool, into a machine roll (parent roll), the diameter of which may be more than 5 meters and which may weigh more than 160 tons.
  • the purpose of the winding is to transfer the fiber web from its planar manufacturing form into a form in which it can be handled more easily.
  • the continuous process of the machine is interrupted for the first time, after which the process continues in stages. Every attempt is made to interlink these stages as smoothly as possible so that the work already performed would not be wasted.
  • the web of the machine roll generated during manufacture is full-width and even more than 100 km long, so it must be cut into partial webs of a suitable width and length for customers and wound around cores into "customer rolls" before dispatch from the mill.
  • this slitting and winding of the web takes place in a separate machine fitted to the purpose, i.e., a slitter-winder.
  • the machine roll is unwound in the unwinding station and the broad web is slit with the slitting section into a number of narrower partial webs, which are wound with the winding section around winding spools such as cores into customer rolls.
  • the slitter-winder is stopped and the rolls, or "set", is removed from the machine. After this, the process continues with the winding of a new set. These stages are repeated periodically until the paper on the machine roll runs out, at which point the machine roll is replaced and the operation restarts with the winding of a new machine roll.
  • unwinding stations are also located in connection with for example off-line finishing stations, typically coating or calendering stations.
  • the machine roll In the unwinding stations of known fiber web production lines, the machine roll is typically conveyed to such unwinding stations that is not connected to the paper machine with transfer rails with a crane and lowered to transfer rails. In applications where the unwinding station is connected to the production line with transfer rails inline, the machine roll is transferred along the transfer rails from reel-up to the unwinding station. In the simplest implementation, particularly in the case of small machine rolls, the machine roll may also be conveyed with a crane directly to the unwinding station.
  • the transfer rails for full machine rolls consist of horizontal or inclined rails with stand-by stations. Along transfer rails, the machine roll is transferred from one stand-by station to another until the unwinding station is reached.
  • the machine roll With horizontal transfer rails, the machine roll is transferred from one stand-by station to another by means of a transfer device, and with inclined transfer rails, by means of rolling based on gravity and stop and release mechanisms.
  • the machine roll in some cases is also transferred from the reel-up to the unwinding station by a transfer cart and for example in publication EP 1266091 B1 is disclosed a transfer cart supported on a floor, used for transferring machine rolls at the height of transfer rails for machine rolls.
  • An unwinding station of typically comprises an unwind stand which holds the machine roll up during unwinding.
  • the unwind stand comprises a first unwind stand on the driving side and another unwind stand on the tending side.
  • the ends of the machine roll are on these unwind stands during unwinding.
  • Locking arms are fastened to the unwind stand with joints; the arms are used for locking the machine roll in place during unwinding.
  • a machine roll located in an unwinding station is connected to a brake generator, which functions as a drive of the unwinder.
  • a reeling shaft handling apparatus comprises either vertical lifting devices or rotatable lifting arms and return rails for empty reeling shafts, located above the transfer rails for machine rolls, often also above the unwinding station or above the slitter-winder.
  • An empty or nearly empty reeling shaft is lifted with a lifting device or with lifting arms to return rails, which normally have a number of return positions.
  • reeling shaft storage is located above the unwinding station.
  • the reeling shaft is transferred from one station to another either by means of a transfer device or by means of rolling based on gravity using stop and release mechanisms.
  • the empty winding shaft is removed from the return rails by lowering devices and moved to the reel-up of the machine with a crane or by a transfer cart.
  • the return rails may also be connected directly to the reel-up's reeling shaft storage rails, whereby the reeling shaft may be transferred directly from the unwinding station to the reel-up.
  • the reeling shaft handling solutions implemented in the prior art are complex, inflexible and expensive. For example, it is difficult to make paths of reeling shaft and machine reel transfer carriages, transfer rails, and transfer and conveyance routes of cranes adjust to changing needs.
  • the handling solutions for reeling shafts require expensive concrete and steel beam structures implemented according to the full machine reel in order to hold up lifting devices, such as cranes.
  • the crane capacity may be reserved, in which case the crane may not be able to respond to transfer needs at a short notice.
  • the machine hall height is not enough for arranging return rails for reeling shafts above the machine reel transferring rails or for the use of a crane.
  • An object of the present invention is to create a new arrangement for handling machine rolls and reeling shafts to achieve simple, flexible and cost effective handling of machine rolls and reeling shafts in connection with production of fiber webs and especially in connection with an unwinding station of a production line for fiber webs.
  • One object of the present invention is to solve at least part of the disadvantages and problems relating to arrangements according to prior art.
  • the arrangement for handling machine rolls and reeling shafts in connection with production of fiber webs comprising a transfer cart for transferring machine rolls and empty reeling shafts and an unwinding station or a corresponding station in connection with production of fiber webs in which an empty reeling shaft is to be replaced by a machine roll, which unwinding station or corresponding station comprises stands for locating the machine roll or the reeling shaft, which unwinding station comprises means for lowering the reeling shaft from the unwind stand to at least onto level of floor to an override location in which the machine roll moved in process direction is circumvented below by the reeling shaft.
  • the arrangement for handling machine rolls and empty reeling shafts is based on using a transfer cart for transferring the machine rolls to an unwinding station and for transferring the empty reeling shafts from the unwinding station.
  • the reeling shaft is advantageously lowered from the rails of the unwinding station to a override i.e. circumvent location near the floor level, on the floor level or below the floor level such that the machine roll is circumvented below by the reeling shaft.

  • the gate rails are inclined such that no transfer device is needed for the machine roll movement and the movement is based on gravity.
  • the gate rails may also be provided with transfer device in cases where it is appropriate.
  • the operations in the arrangement are advantageously automatized.
