Definitions

  • the invention relates to fiber web machines, such as paper, board, and chemical pulp machines.
  • the invention relates to a movable storage and to a method for receiving, storing and handing over rolls or similar items, such as winding shafts and/or machine reels, intended for the handling of a web-like material.
  • the present invention also relates to the manufacturing lines of fiber webs.
  • the present invention also relates to a computer program for implementing the method and controlling the storage.
  • paper is manufactured in machines together forming a paper 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 200 m/min and the width of a paper web may be more than 11 meters.
  • paper manufacturing operates as a continuous process.
  • the finished paper web being output from the paper machine is wound with a winder around a winding shaft, i.e., a reel spool, into a machine reel, 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 paper web from its planar manufacturing form into a form in which it can be handled more easily.
  • the continuous process of the paper 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 reel generated during paper 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 paper 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 reel In the slitter-winder the machine reel is unwound, 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 reel runs out, at which point the machine reel is replaced and the operation restarts with the winding of a new machine reel.
  • the paper machine may produce more paper than a single slitter-winder is able to process, in which case more than one slitter-winder is needed in the paper manufacturing line.
  • the slitter-winders are located sequentially in the direction of the machine line at a certain distance from each other.
  • the first slitter-winder is typically arranged as an "inline” slitter-winder, which means that the slitter- winder is aligned with the paper machine and the winder, i.e., located in the main machine line.
  • the second slitter-winder is an "offline" slitter-winder, which may be positioned aligned with the paper machine after the first slitter-winder.
  • Both slitter- winders output customer rolls, which are normally first conveyed with roll conveyors to, e.g., a roll packaging machine for packaging and finally to storage before being sent to customers.
  • the machine reel In the slitter-winders of known paper machine lines, the machine reel is typically conveyed to such a slitter-winder that is not connected to the paper machine with transfer rails with a hoist and lowered to transfer rails, which are typically positioned so that the height of the machine reel's centre from the floor surface is about 2.5 meters. A minimum distance of 500 mm is typically applied as a safety distance between the machine reel and the surface below the machine reel, such as the floor surface. In applications where the winder of the paper machine and the slitter-winder are connected to each other with transfer rails inline, the machine reel is transferred along the transfer rails from the winder to the slitter-winder.
  • the machine reel may also be conveyed with a hoist directly to an unwind stand.
  • the transfer rails for full machine reels consist of horizontal or inclined rails with stand-by stations. Along transfer rails, the machine reel is transferred from one stand-by station to another until the unwinding station is reached. With horizontal transfer rails, the machine reel 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.
  • An unwinding station typically consists of an unwind stand which holds the machine reel 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 reel 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 reel in place during unwinding.
  • a machine reel located in an unwinding station is connected to a brake generator, which functions as a drive of the unwinder.
  • a winding shaft handling apparatus consists of either vertical lifting devices or rotatable lifting arms and return rails for empty winding shafts, located above. An empty or nearly empty winding shaft is lifted with a lifting device or with lifting arms to return rails, which normally have a number of return positions.
  • a return station (a winding shaft storage) is located above the unwinding or the slitting and winding section. Along the return rails, the winding 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 and moved to the winder of the paper machine with a hoist.
  • the return rails may also be connected directly to a winder's winding shaft storage rails, whereby the winding shaft may be transferred directly from the slitter-winder to the winder.
  • storage spaces are needed in the slitter-winder area for full machine reels, partly filled machine reels and empty winding shafts.
  • such storage spaces at the finishing end of the fiber web manufacturing line are located in the main machine line between the main devices of the manufacturing process in the winding and slitting-winding area, i.e., between the slitter-winders, unwinders of the slitter-winders, and the windup belonging to the paper machine or a coating machine.
  • the winding shaft handling solutions implemented in the prior art are inflexible. For example, it is difficult to make paths of winding shaft and machine reel transfer carriages, transfer rails, and transfer and conveyance routes of gantry cranes adjust to changing needs.
  • the handling solutions for winding shafts require expensive concrete and steel beam structures implemented according to the full machine reel in order to hold up lifting devices, such as hoists.
  • the hoist capacity may be reserved, in which case the hoist may not be able to respond to transfer needs at a short notice.
  • the handling solutions for winding shafts are mainly based on the use of a hoist.
  • the load to be lifted is not necessarily within reach of the hoist's lifting means.
  • transfer rails intended for winding shaft traffic and located between a winder and a slitter-winder are situated above transfer rails intended for machine reel traffic and located between the winder and the slitter-winder, thus forming an obstacle for lifting with a hoist or at least make the lifting a complicated procedure as the load to be lifted must be navigated among the transfer rails above.
  • a rejecting location for the bottom-ends of machine reels or partially filled machine reels in the pulper is arranged in connection with transfer rails arranged for machine reel traffic, whereby the fixed transfer rails above hamper the handling of winding shafts to be emptied, implemented with a hoist.
  • the publication EP 1266091 B1 discloses a transfer carriage supported on a floor, used for transferring machine reels at the height of transfer rails for machine reels.
  • a movable storage is provided, supported on a floor and movable between at least two target stations, for receiving, transferring and handing over rolls, winding shafts and/or machine reels intended for the handling of a fiber web, the movable storage comprising reception members for receiving and holding up the load being handled at both its support ends.
  • the movable storage comprises at least one vertical support member supported on the floor for supporting the reception members at a fixed height or in a manner enabling adjustable height and for holding the load up so that, during operation, the movable storage and the at least one roll, winding shaft and/or machine reel being handled is moved supported on the floor by means of at least one vertical support member above a fiber web manufacturing device and/or a finishing device.
  • a method for handling rolls, winding shafts and/or machine reels intended for the handling of a fiber web by means of a movable storage supported on a floor, the movable storage being movable between at least two target stations and comprising reception members for receiving the load being handled and holding it up at both its support ends.

  • the movable storage may be movable between at least two target stations.
  • the target station may be a device of the fiber web manufacturing process; a storage stand; a storage rail; a transfer rail; a rejecting location; a location related to roll maintenance, such as a roll grindery; or another movable storage arranged for a roll, winding shaft and/or a machine reel.
