Description
- This application is a U.S. national stage application of International Application No. PCT/FI01/00176, filed Feb. 21, 2001, and claims priority on Finnish Application No. 20000441 filed Feb. 25, 2000, the disclosures of these applications being hereby incorporated by reference herein.
- Not applicable.
- The present invention relates to methods and apparatus for manufacturing paper or board webs in an on-line manufacturing process, in which the web is passed directly to a finishing device and the web is wound into machine reels.
- Recently, the use of on-line manufacturing processes has become more common in making paper and board webs, in which processes the entire paper or board machine operates as an integrated production line from the beginning to the end, thus also comprising the desired means for finishing the web. A manufacturing process such as this is, however, problematic in the sense that when a partial entity is damaged, in particular in an unscheduled shutdown and/or in maintenance of a finishing device, the utilization rate of the entire production line has to be reduced and the entire production process even has to be stopped. It goes without saying that this is extremely expensive and involves high costs.
- Thus, methods are known in the state of the art for producing a paper or board web in which the web is passed from the dryer section directly to finishing, that is, we are discussing an on-line manufacturing process in which the utilization rate of the entire manufacturing line has to be dropped if there is some disturbance or a roll is replaced in a finishing device. In that connection, the web also usually has to be run into the pulper. In some cases, the entire production line has to be stopped because of a problem that occurs in a finishing device. In addition, in manufacturing processes in which the web is passed from the dryer section directly to on-line finishing, it has been possible to run only grades that can be finished at the running speed used in the manufacturing line, in which connection it has not been possible to make in this process, for example, grades which are calendered to very high quality, which generally require speeds lower than the normal running speed of the machine, but, instead, it has been necessary to perform calendering with a separate calender, for example, with an off-line calender.
- A problem in the production of a paper or board web has also been that if at some stage of production a web has been produced which is not suitable for the purpose desired in respect of its quality requirements, it has been necessary to run it into the pulper, from which it has been passed into pulp towers, in which connection the volumes of the pulp towers have been dimensioned to be large, for instance, such that they can hold the broke of 8 hours' running time.
- An object of the invention is to provide a solution to the problems described above.
- A particular object of the invention is to provide an arrangement by which the utilization rate of a paper or board machine is maximized and attempts are made to reach a situation where the paper machine can operate without interruption in spite of problems occurring in finishing devices.
- As taught by the invention, in the process of manufacturing a paper or board web, the state of the finishing devices is monitored in connection with the finishing devices and, when the web cannot be conducted to a finishing device for treatment, for example, because of a disturbance situation or roll replacement, the web is passed via other finishing devices or so as to be directly wound, and it is wound into a machine reel in order to be stored, from which machine reel the paper or board web is later unwound and finished, for example, during a shutdown of the paper machine caused by something other than a finishing device, or the machine reel is taken to a finishing device of another line of the mill or to a finishing device of another mill, either an on-line or an off-line finishing device, in order to be finished. The winding is performed either with a reel-up placed at the end of the machine or the winding is performed with a reel-up placed at a suitable location in connection with the finishing devices. When needed, unwind stations are also placed in connection with the finishing devices, from which stations the web can be passed so as to be finished during a shutdown of the other parts of the production line. The reel-up may also be such that it operates both as an unwind and as a windup station. When outdated paper or board machines are modernized, it is possible to make use of reel-ups which already exist in the machine and which can be modified, for example, such that they function both as unwind and as windup stations.
- In accordance with the invention, the paper or board web production line comprises means for monitoring the state of the finishing devices and for controlling the production line such that, when there occurs a disturbance situation or a roll is replaced in a finishing device, the production line is controlled such that the web is passed so as to be reeled, and the wound paper reels are unwound and finished during a shutdown caused by a disturbance situation in the paper machine or by something other than a finishing device.
- In accordance with an advantageous application of the invention, in connection with a finishing device there is an apparatus for unwinding the machine reel and it is also possible to pass the web from the unwind station to the reel-up and to run the finishing device as an independent off-line device. The unwind apparatus is placed, for example, in connection with a finishing device at a suitable location in the line, for example, on top of the machine or after the reel-up. This kind of equipment used in connection with the invention is advantageously as simple as possible, including primarily means needed for control of tension.
- In some applications of the invention, the manufacturing line is provided with means required for tail threading and transfer of the web bypassing a finishing device in situations where the web is wound by means of the reel-up into machine reels to be placed in storage, and the web is thus not finished on-line. The web can also be passed to the reel-up through the finishing devices, in which connection the finishing devices are run, so to speak, with the stations open.
- The threading which bypasses a finishing device can be accomplished by means of separate equipment, for instance, at an edge of the web opposite to that of the tail threading proper, and the transfer of the web bypasses a finishing device most advantageously above or below. In off-line situations, threading can be accomplished in a suitable manner known in itself. As such, any threading methods known in themselves can be used for tail threading: manually, using threading ropes, threading bands, blowings, etc.
- When using the method according to the invention, the problems occurring in a finishing device do not drop the utilization rate of the entire production line. For instance, when a finishing device is out of operation because of a damaged roll, a new threading operation is performed and production is continued during replacement of the roll and the web is wound into machine reels. The unfinished machine reels are moved, for example, onto storage rails to wait and during the next shutdown, not caused by a finishing device, the machine reels are finished off-line. Moreover, when using the invention, the roll replacement time is not critical because the web being produced can be stored on machine reels.
- The invention also enables running of paper and board grades which cannot be accomplished at on-line speeds, in which connection the machine reels run during roll replacement or another disturbance situation in a finishing device can be finished, when needed, into high-quality rolls at a lower speed during a subsequent shutdown instead of running down the entire line or running the output into the dry end pulper during roll replacement or another disturbance, as done today.
- When a new paper machine is started up, in the arrangement according to the invention, a paper or board web from an adjacent machine or a neighbouring mill can be introduced into a finishing device before the initial end of the machine has been assembled.
- In accordance with an advantageous application of the invention, for instance, broke is wound into a reel on a reel-up, which broke can be transferred later into pulp towers or possibly to another suitable use. In that connection, the volume of the pulp tower can be reduced to correspond, for instance, to a running time of three hours. On a reel, the broke takes the smallest storage space.
- The invention can be applied in connection with all types of on-line finishing devices, for example, calenders and coating machines. The calender can be, for example, a multi-roll or a soft calender.
- In accordance with an advantageous embodiment of the invention, the invention is used in producing on-line sack paper, White top liner, sack and liquid packaging board. This embodiment relates to an on-line calendering method in which, for example, an Metso Paper, Inc. OptiDwell® calender is used as a calender. The web is passed to a reel-up after calendering.
- The invention is also suitable for use in connection with the manufacture of many types of board and paper, for example, in LWC paper production lines, in which, for example, an on-line two-side coating device marketed by Metso Paper, Inc. under the trademark SymSizer and, for example, a calender marketed by the applicant under the trademark OptiLoad® are used.
- In the following, the invention will be described in more detail with reference to the figures in the accompanying drawing, to the details of which the invention is, however, not by any means intended to be narrowly confined.
- FIG. 1 schematically shows a basic application of the method according to the invention as a block diagram illustration.
- FIG. 2A schematically shows an application of the method according to the invention when using the normal running mode.
- FIG. 2B schematically shows the application shown in FIG. 2A when a finishing device is under maintenance.
- FIG. 2C schematically shows the application shown in FIGS. 2A and 2B when the paper or board machine is under maintenance.
- As shown in the schematic block diagram illustration of FIG. 1, a web produced on a paper or
board machine 15 and dried on itsdryer section 20 is passed to finishing devices, for example, to anintermediate calender 60, acoating machine 50 and therefrom to acalender 10 and further to a reel-up 30 and astorage 40. Thefinishing steps monitoring units finishing device up 30 in order to be wound into machine reels and stored in thestorage 40. When the system detects that there is a shutdown in the paper orboard machine 15, the machine reel/reels in thestorage 40 is/are unwound and the web is passed to the finishing devices, for example, to theintermediate calender 60 and/or to thecoating machine 50 and/or to thecalender 10 in order to be finished, after which the web is wound on the reel-up 30. The flow of information is schematically denoted by arrows, anddata 22 from the control system of the paper machine are passed to monitoringdata 42, to which also data from themonitoring units intermediate calender 60, thecoating machine 50, thecalender 10 and the reel-up 30 is controlled by means of feed-back 43. Of course, from themonitoring data 42 there is control to the reel-up 30 and to the storage data in thestorage 40. In this manner, in the method according to the invention, a paper or board web can be continuously manufactured at desired speed on thepaper machine 15, and the machine need not be stopped because of a fault that occurs in a finishing device, for example, in theintermediate calender 60 or in thecoating machine 50 or in thecalender 10, but, instead, the web that is being produced can be stored and treated at a later stage with said finishingdevice - In the schematic embodiment example shown in FIG. 2A, in normal running, a web W is passed from a
dryer section 20 of a paper or board machine via aguide roll 13 to acalender 10 and, after that, via aguide roll 33 to a reel-up 30, on which the paper web is wound into a machine reel R1. The reeling drum of the reel-up 30 is denoted by thereference numeral 34. Finished machine reels RN have been transferred onto storage rails 40 to await further processing. The guide rolls of the web W which are not used in normal running are denoted by thereference numerals - As shown in FIG. 2B, during a shutdown that occurs in the
calender 10, the web W is conducted from thedryer section 20 via guide rolls 13, 43A, 33 past thecalender 10 to the reel-up 30, on which it is wound into machine reels R1, RN, which are transferred to astorage 40 or to another calender (not shown) to await finishing. - As shown in FIG. 2C, during a shutdown of the paper machine caused by something other than the finishing device, a machine reel/reels RN containing unfinished web, situated in the
storage 40, is/are unwound by means of an unwindstation 70, and the web W is passed to thecalender 10 by means of guide rolls 43B, 43A, 13 in order to be calendered and therefrom further via theguide roll 33 in order to be wound. Other possible positions of an unwindstation 70′, 70″ are denoted by broken lines in the figure. - Corresponding parts in FIGS. 2A to2C are denoted by identical reference numerals, and the running direction of the web W is denoted by arrows S. The embodiment example of the invention shown in FIGS. 2A to 2C is highly schematic and the finishing devices may, in addition to the
calender 10 shown in the figures, comprise many other types of calenders and, in addition, different types of coating machines or other finishing devices. In addition to the application shown in the figures, transfer of the web W can also be accomplished above the finishing device/finishing devices or by running the web through the finishing devices with the finishing stations open. Both the unwind and the windup stations can be situated at suitable locations in connection with the finishing devices, above or below or between/after the finishing devices. When desired, the reel-up 30 proper may also serve as an unwind station. The storage may also be located somewhere else instead of the position shown in the figures. The unfinished machine reels RN are moved, when needed, for example, with a hall crane (not shown) or by other suitable means to an unwind station.
