Description

FIELD OF THE INVENTION The present invention relates to a fiber web production and / or processing line, more particularly to a fiber web production and / or processing line according to the preamble of claim 1. comprising a control system, comprising an arrangement for processing machine rolls and / or winding shafts, the fiber web production line comprising at least two process units for carrying out the fiber web manufacturing and / or processing process and at least one crane arrangement for moving machine rolls and / or roll shafts. The invention also relates to a method for treating machine rolls and / or winding shafts of a fiber web production and / or processing line according to the preamble of claim 16, wherein the method comprises manufacturing at least two process units of the fiber web manufacturing and / or processing line. and / or a processing process, and wherein machine rolls and / or winding shafts are moved between the first and second process units.

As is known in the art, paper is produced on machines which together form a paper production line which can be hundreds of meters long. Modern paper machines can produce more than 450,000 tonnes of paper per year. The speed of the paper machine web can be up to 33 m / s and the width of the paper web can be over 11 m.

In papermaking lines, papermaking is a continuous process. A paper web made from a Pape-25 crusher is rolled around a winding spindle, a reel spool, into a machine roll, which can be over 3.5 m in diameter and over 100 tons in weight. Once the diameter of the machine roll has been determined to be predetermined, the reeling on an empty tamprour roll is started without interrupting the pre-roll paper production. The purpose of the winding is to convert a flat web of paper into a more manageable shape. With the reel, the continuous process of the paper machine is interrupted for the first time and switches to intermittent operation. The aim is to achieve this periodicity with the best possible efficiency so that the work already done is not wasted. 1 2

The papermaking line can perform post-process treatments, such as coating or 2 treatments, such as calendering, on certain types of paper, such as coating. These processes are either separate installations or processing in the manufacturing process.

The web of machine roll produced in papermaking has a full width and even more than 5,100 km, so it has to be cut into widths and lengths suitable for paper mill customers, and rolled around the cores in a so-called. customer rolls before shipment from the paper mill. This web longitudinal cutting and winding takes place in a separate machine known in the art, i.e. a winder.

As is known in the prior art, in a winder, the machine roll is unwound, the wide web is cut by a cutting member into a number of narrower subwires which are wound by a winding member around customer cores such as cores. When the customer rolls for each sub-web are simultaneously made, the winder is stopped and the rolls, or so-called "rollers", are stopped. the move is removed from the machine. After that, the process is continued as a roll of 15 new removals. These steps are repeated periodically until the paper runs out of the machine roll, whereby the machine roll is replaced and operation begins again as a new machine roll. There are often two sliders per paper machine, one on the center line of the paper machine and the other on the side of the center line of the paper machine. Thus, the transfer of the full machine roll must be arranged between the paper machine reel and the unrolling unit of both winders. 1 2 3 4 5 6

Processes carried out on papermaking lines thus require the transfer of machine rolls and empty winding shafts from one process to another. Because of the high weight of the machine roll, their transfer during the process is typically carried out along the rails, in accordance with prior art, with the aid of and supported by machine members arranged therein. Longer distances, and especially transverse to the center line of the paper machine, are typically made by means of transport trolleys which are arranged along the rails of the data center floor. Solutions of this kind are very inflexible from the process point of view, for example, in the order of handling machine rolls.

30 2

The object of the invention is to provide a fiber web production and / or processing line according to Claim 1, preamble 3, comprising an arrangement for processing machine rolls and / or roll 4 axis with a control system, the fiber web production and / or processing line comprising at least two process units. 6 35 for carrying out the manufacturing and / or processing process and for transferring at least one crane arrangement between the machine rolls and / or the winding shafts between the process units, thereby improving the efficiency of the fiber web manufacturing and / or processing line. It is also an object of the invention to provide a method according to the preamble of claim 16 in connection with a fiber web production and / or processing line for treating machine reels and / or winding shafts with an arrangement of machine reels and / or winding shafts, the method comprising at least two carrying out a process for manufacturing and / or processing a fibrous web, and moving machine rolls and / or roll shafts between the first and second process units, and improving the efficiency of the fibrous web manufacturing and / or processing line.

This object is achieved by the fiber web production and / or processing line according to the invention mainly in that the crane arrangement is an automatic crane with a control system and that the automatic crane control system is in communication with the control units of the process units or are part of the same control system.

15

This arrangement produces the effect that the arrangement of processing of machine reels and / or winding shafts is formed as a whole into a system which can be controlled according to the overall needs of the process and thus provides highly flexible movement of the machine reels and / or winding shafts. In addition, the arrangement according to the invention makes handling of machine reels and / or winding shafts safer for operating personnel.

According to an embodiment of the invention, the first process unit is a reel which is adapted to make machine rolls 25 on the reel shaft and which first process unit comprises a control system or is adapted to communicate with the control system or part thereof, and the control systems of the reel are part of the same control system.

This enables the auto-crane to automatically ensure that the machine rolls produced by the reel are removed from the reel, thereby ensuring its continuous operation. 1

In the arrangement, when one process unit is a winder and the other process unit comprises a control system or is adapted to communicate with the control system or part thereof, the control systems of the reel, automatic crane and winder 4 are in communication with each other or are part of the same control system.

This enables the auto-crane to automatically remove the machine rolls produced by the reel from the reel and thereby ensure its continuous operation, and to provide the winder to the winder for processing directly from the reel or from the reel / reel.

Preferably, the control system of the machine reel handling arrangement of the fiber web production line comprises a recording part or parts for storing and using process and / or control information in the automatic crane control system to execute a predetermined overall process, the automatic crane being integrated into the fiber web production and / or processing line.

15

According to a preferred embodiment of the invention, at least one security area is provided in the domain of the automatic crane, comprising an identification arrangement for detecting human presence. With such an arrangement, the traffic of the automatic crane can be controlled so that it does not exceed 20 people working in the safety zone, thus improving occupational safety.

Preferably, the security area comprises at least two separate security areas. In this case, the traffic of the automatic crane may be directed to take place via another separate security zone when the presence of the target is detected in the second separate security zone. This feature 25 significantly improves the flexibility of using the arrangement, improving the simultaneous auto-crane traffic and maintenance operations on the fiber web production and processing line.

Advanced, each process unit is limited to a separate security area, whereby the flexibility and simultaneous operational safety of the automatic crane are maximized when the automatic path of the automatic crane is arranged to depend on the status information of the safe area. Preferably, then, the identification arrangement is in communication with the control system for transmitting status information of each safety zone to the control system, whereby the auto-crane automatically selects its passage to pass through safety zones where the presence of objects is negative, i.e., without maintenance personnel.

5

At its simplest, each security area comprises a fence or the like and an associated port or the like, and the detection arrangement comprises a gate or an associated sensor to identify the position of the port. The security area may also comprise, for example, a security mat with a sensor, or the like, for detecting a person on it. Further, the gates of the safety area can be arranged to be lockable in situations where the area is along the crane's passage. The security area may also be an area monitored by cameras or similar detection means, whereby the detection means communicates to the control system the person in the security area.

10

In the method according to the invention, at least two process units of a fiber web production and / or processing line carry out a fiber web manufacturing and / or processing process, and in which machine rolls and / or winding shafts are moved between said at least two first and second process units. The objects of the invention are mainly achieved by moving the machine reels and / or winding shafts by means of at least one automatic crane equipped with a control system by providing the automatic crane control system with information on the control units of the process units and / or the processing arrangement. controller. Thus, the operation of the 20 automatic cranes is controlled by substantially real-time information from the steering system. According to a preferred embodiment, the first process unit of the fiber web production and / or processing line is a reel which produces machine rolls on the winding axis under the control of the control system, and the produced machine rolls are displaced by the automatic crane raised by the control system. Substantially real-time information can thus be used to control the movement and operation of the automatic crane 25.

According to one embodiment of the invention, at least one security area is provided in the domain of the automatic crane, from which status information is transmitted to the control system 30 for detecting human presence, and the movement path of the automatic crane is selected depending on the security area status information. 1 2 3 4

In the method, the second process unit 2 of a fiber web production and / or processing line processes machine rolls produced by the first process unit, wherein in the situation 3 where one process unit is ready to receive the machine roll, the control system 4 controls at least one automatic crane to feed the machine roll to the second process unit not ready to receive the machine reel, the control system controls the crane to transfer the completed roll from the first process unit to the machine reel / reel shaft stock.

5

According to one embodiment of the invention, the existing fiber web production line is modernized by providing the production line with an automatic crane equipment comprising a control system and further by communicating the control system with the fiber web production line and / or the reel control system 10. If necessary, the stop positions of the reel rail can also be locked.

Other additional features of the invention will be apparent from the appended claims.

15

As used herein, a fiber web machine refers to various fiber web manufacturing or processing equipment, such as paper machines, coating machines, calenders and cardboard machines. In this context, an automatic crane is also meant a semiautomatic crane which is mainly automatic in operation but in which the start / stop of at least one of the 20 phases / sub-phases may be manual, e.g. Further, in this specification and in the following claims, the term process unit must also include a subprocess or processing function of a manufacturing process, for example having its own control system and / or security area.

25

The control system used in connection with the invention may be wholly or partly decentralized or centralized, whereby the performance of the control system may be implemented either wholly or partly in a centralized or decentralized manner. The control system may be a control system of one or more process units or a separate system, for example a factory computer. The control information and / or storage information of the control system may be distributed in one or more units. The control system can also optimize production operations and / or relocations required for storage situations, and, if desired, simulate the required paths. 1

The safety area may consist of the whole or some part of the operating area of the automatic crane, and further, the safety area of the process unit may comprise several safety areas 7. In addition, the automatic crane can have one or more security areas, such as corridors, that are not directly related to the process units. The safety zone can also be dynamically variable according to control. The range of operation of the automatic crane may include areas of automatic operation as well as areas which require 5 manual or partial control (e.g., start-up).

The invention provides numerous advantages. The arrangement of the machine reels according to the invention provides e.g. increased process flexibility and operational reliability by avoiding "first-in-first-out" 10 operation of conventional rails and wagon based systems and allowing each reeling axis / machine roll to be handled solely on demand. In addition, the auto crane is also available for service-related lifts, such as the retrieval / removal of replaceable spare rolls, thereby saving capacity as the control system takes care of these lifts at the production-optimum stage. During maintenance, the crane can also be operated manually. Furthermore, the invention allows for a much more flexible design of the lay-out of the production line, since the machine roll / roll axis traffic is very versatile. In particular, the invention significantly improves operational safety over prior art, since machine roll / roll axis traffic can be assuredly carried through areas where no persons are present at the same time as the traffic occurs. 1 2 3 4

In the following, the invention and its operation will be described with reference to the accompanying schematic drawings, in which Figure 2 schematically shows a fiber web production and processing line according to one embodiment, 3 Figure 2 schematically shows a fiber web production and processing line, Figure 4 is a schematic cross-sectional view of a further embodiment of a fiber web according to another embodiment, Figure 5 is a schematic cross-sectional view of a fiber web production and processing line of another embodiment, and Figure 6 is a schematic view of a 35 and the processing line.

8

Figure 1 schematically illustrates a fiber web production and processing line 10 according to one embodiment, its machine reel handling arrangement 50. In this embodiment, the manufacturing and processing line comprises a fiber web machine 15 not shown for clarity and a first process unit associated therewith. 5 rollers 20. The roller 20 is known per se for its basic function and structure. The roller 20 comprises a full machine roll pickup station 25 to which the roller moves the finished machine roll 30. The roller also comprises an empty winding shaft 30 'receiving station 35, which is preferably a support roller roll support arrangement, such as a so-called. alkurullauslaitteisto. In this embodiment, the roller machine roll pickup station 25 10 may be a relatively short rail or a roller carriage which, upon completion of the roll, is sufficiently displaced from the roller cylinder. With the reel, the finished reel is brought to a predetermined pickup position from where it is moved forward in the handling process.

If the roller rails are long when applying the solution 15 of the invention, for example to modernize a fiber web machine, the stops of the existing rail are locked, whereby the position determined by the stop becomes the storage place for the machine roll of the system of the invention. When this storage location information is available to the automatic crane control system, the existing busbar can be effectively utilized in the machine reel / reel shaft handling arrangement.

20

The fiber web machine 15 and its machine reel handling arrangement 50 have a control system 45 which controls the operation of the apparatus. The control arrangement comprises a control system 45.1 controlling the operation of the retractor 20. The control arrangement may be wholly or partly decentralized or centralized, whereby the control system operations may be implemented either wholly or partially in a centralized or decentralized manner. The control system is also arranged to communicate with the factory's production control system, so that, for example, the response to an order change is as fast as possible. 1

The manufacturing line in this embodiment comprises two winders 100, 200 30 and a winding shaft / machine roll storage 55, which are also process units within the scope of the invention. The winders are arranged parallel to the fiber web machine so that the first winder 100 is on the center line 12 of the fiber web machine 15 and the second length cutter 200 is adjacent thereto. A length-cutter control system 45.3, 45.4 is provided to control the operation of the winders. Also, in the case of winders, the control system 35 may be wholly or partly decentralized or centralized, whereby the control system operations may be performed either wholly or partially in a centralized or decentralized manner. The longitudinal cutters 100, 200 comprise a unwinding station 110, 210 in which the machine roll is unwound, leading the web to the winder to be cut into webs and rolled into customer rolls. In the case of the winders 100,200, the unrolling station typically also functions as a machine reel import station 120, 220 or there is a separate machine reel import station 120, 220 in the vicinity of the unrolling station. and its data. Further, the control system 45 comprises a recording section 45.6 for storing and / or importing machine rolls and / or reel shafts of machine process rolls and / or reel shafts for each process unit included in the system, allowing proper and / or appropriate machine rolls as well as the winding shaft to the right position just when you want it to happen. The position of the machine roller importing station and winding shaft retrieval station of the winders is thus stored in the recording section 45.5 of the control system 45, wherein the crane arrangement 15 is able to retrieve a full / new roll and retrieve an empty winding shaft from the winder. 1 2

The machine reel handling arrangement of the invention also includes a crane arrangement 300 for transferring the machine reels and / or reel shafts between process unit units of the processing line to accomplish a predetermined overall process. The crane arrangement 2 has a specific domain in which it can work. The crane arrangement according to the invention is an automatic crane capable of automatically operating under the control of a program and / or external commands stored in its control system. In the following, reference numeral 300 denotes both the crane assembly in general and the automatic crane in particular. The automatic crane comprises a control system 45.2 which controls its operation. The automatic crane is made up of rails 315 parallel to the fiber web machine and a beam 320 supported on and substantially transverse thereto. The beam 320 is movably supported on rails 315 to pass over the fiber web machine and other process units. The automatic crane control system 45.2 is also arranged to control the movement of the beam in the machine direction. A lifting device 325 is arranged in connection with the beam 320 so that it is movable along the beam also controlled by the control system 45.2. The lifting device further comprises means 330 for rotating the lifting device horizontally with respect to the beam, which enables the machine roll and / or winding shaft to be transported, picked up and released at a freely selectable angle relative to the machine direction. The angular position of the hoist 325 is also controlled by another control system 45.1. The lifting device 325 further comprises gripping means for engaging the winding shaft (not shown).

The winding shaft-Zkon roller storage 55 of Fig. 1 comprises a plurality of winding shaft clips 57 with a pair of gantries in the machine direction. The treatment arrangement 5 according to the invention allows the orientation of each pair of trestles to be freely chosen according to the shape of the space available so that the space can be utilized as efficiently as possible. Machine rolls and / or reel shafts can be stored, for example, directly in machine directions, as shown in Figure 1 with the reel shafts, or obliquely, as shown in Figure 1 with a machine reel. The position of the trestles is stored in the storage section of the control system 45.2 of the automatic crane 10, whereupon the crane 300 can use the trestles as a roll axis and / or machine roll storage if required by the machine roll processing process. The position of the positions of the reel shafts / machine reel stock 55 reel shafts and / or machine reels is stored in the crane equipment control system 45.2, whereby the control arrangement is capable of guiding the crane to bring or retrieve the reel shaft or machine reel consisting of the roll shaft shackles 57, the position of the roll shaft / machine roll store 55 can be easily changed by moving the shackles to a new location in the crane system domain and re-storing their position in the control system. The control system may thus be associated with a storage system to optimize production and / or storage needs. 1

The automatic crane may be equipped with a balance, whereby the mass of each machine roll can also be stored in the control system 45.2, whereby the system also knows how much paper each roll of machine has. In this case, for example, 25 previously formed machine rolls, some of which have been disassembled from the fibrous web, can later be used with a winder to complete a customer roll order when the amount of web on the machine roll is sufficient. the supplement. Information on the amount of paper contained in the reel can also be transferred to the system information from, for example, the reel air control system. Thus, the invention provides a flexible response to the running conditions of the winder. The amount of paper in the deficient machine rolls can also be transferred to the control system from the process unit where the defective roller was generated. In addition, the system can optimize the use of machine rolls according to the needs of the longitudinal section / stock situation, for example, by selecting the machine roll so that the longitudinal sections of the roll are uniform. Other gauges, such as a 35-roll hardness gauge, can also be fitted to the automatic crane.

11

Preferably, the handling arrangement comprises a security area 60 located within the domain of the automatic crane. This maximizes the operational safety of the in-process operation with the automatic crane operating as part of the process. The security area comprises an identification system for recognizing the presence of a human, such as a member of the production line operating staff. Preferably, the security area is a fenced area comprising an identification arrangement 65, 65.1, 65.2, 70.1, 70.2, 70.3 for detecting the presence of operating or other personnel within the security area. Each of the process units that the operating personnel may need to access while operating the fiber web production and / or processing line is preferably provided with its own separate security area and its own identification arrangement. In the embodiment of Figure 1, this is accomplished by providing gates 65.1 with an enclosed sensor 65.1 throughout the security area fence 65 and detecting the opening and closing of the gate. This allows the control system for the automatic crane to be informed of the presence of persons in the safe area. A separate security area for each process unit is also provided with its own gate 65.2 and its associated 15 sensors 70.2. This enables the automatic crane control system to know which particular process unit is present. The identification arrangement 65, 65.1, 65.2, 70.1, 70.2, 70.3 is in communication with the control system 45 for transmitting the status information of the security area identification arrangement to the crane arrangement control system 45.1. In this way, for example, the presence of the operating personnel can be taken into account in determining the movement paths of the crane system lifting device 325 such that the area provided by the positive presence signal can be temporarily excluded from the lifting device's path. The identification arrangement may comprise a plurality of sensors 70.1, 70.2, 70.3 located in different areas, whereby the control system has access to sufficiently specific information about the presence of personnel in different parts of the security area. In Jois-25 applications, instead of or in addition to the actual physical fence, the area or portion thereof may be defined, for example, by suitably located motion detectors 70.3, whose signal determines the area status of the lifting device. In this way, the operating staff can safely work with one or more process units while the line is in use. A security area can be provided with an area 30 along which machine rolls / reels can always be moved to process units that are not blocked by the identification arrangement. Such an area can be relatively narrow, because with the arrangement of the invention, the machine roll can be kept substantially parallel to the displacement movement. In addition, a notification system may be provided in connection with the system to provide a warning / warning to a person in the safety zone when the safety zone 35 has to be released as a gangway. For example, it may be indicated that after a certain period of time, the safety zone must be free for the crane to pass, otherwise production will be disrupted.

The fiber web production and processing line shown in Fig. 1 operates in normal use 5 such that the fiber web machine 15 continuously produces the web which is rolled on a machine reel with a rewinder 20. At the same time, the winders are These processes are not fully synchronized, whereby the machine reel handling system 10 according to the invention is used to provide the machine reel and / or spindle shaft traffic in the most efficient manner possible.

The retractor control arrangement 45.1 receives information from the retractor when each full machine reel is ready to be dispensed, i.e. can be removed from the retractor. This information is also made available to the crane system control system 45.2. At this stage, the crane system 300 may retrieve the machine roll from the retractor and deliver it either directly to the winder if the crane arrangement 300's control system 45.2 has been advised by either winder control system 45.3, 45.4 that this may or may be the case. If this is not the case, the crane system puts the machine roll into the roll-20 reel / machine roll store 55 to wait for either winder information about the need or possibility of receiving the machine roll.

Particularly in a situation where neither of the winders 100, 200 is capable of receiving the finished machine reel as it is completed, the automatic machine 25 transfers the finished machine reels from the reel 20 to the reel shaft / machine reel stock 55 so that the fiber web production process itself is not disrupted. When the recording section of the automatic crane control system 45.2 contains the current position of each reeling axis within the system and information on the amount of fiber web on the reeling shaft and further information about retrieving, storing, and / or importing the reeling shafts can be handled very flexibly. Figure 1 illustrates a situation in which the crane system 300 is attached by a hoisting device 325 to a finished machine reel 30 and is transferring it to a first winder 100 where the machine reel import station 120 is empty. 1

Figure 2 schematically illustrates a fiber web production and processing line 10 according to another embodiment, which substantially corresponds to the fiber web production and processing line shown in Figure 1, except that the winders are disposed differently to the fiber web machine. In this embodiment, the longitudinal cutters 100, 200 have a common winding shaft retrieval station 130, 230, which here consists of rails connecting the cutters. Underneath the pick-up station, there may also be 5 pulpers where the bottom of the machine roll can be disassembled. The winders are disposed opposite so that the web direction of travel is both away from the import position of the machine reels.

Fig. 2 shows an exemplary situation in which the winder shaft common pick-up station 130, 230 of the winders 10 has an empty machine roll waiting for the lower paper layers of the roll to be discharged into the pulper. The hoist is moving the completed machine roll to the 30 machine roll storage location to wait for a new full roll to be delivered to the winder import station. In this way, rewinding can continue without interruption. It is also seen in the figure that the machine roll direction is turned 15 by machine lifting means 325, whereby storage requires less transverse space.

Figure 2 further shows a roll unloading position 75 in connection with the retractor 20, where, for example, the bottom of the roll can be discharged to a pulper below the machine plane through a pulley opening 85. Each of the process units, the retractor 20 and the reel unloading site 75 form their own separate safety zone, whereby the lifter is guided from outside this safety area by the control system of the automatic crane when the person is at the reel ejection site. 1 2 3 4 5 6 7 8 9 10 11

Figure 3 schematically shows a fiber web production and processing line 10 according to another embodiment, which again essentially corresponds to the structure and 3 function of the fiber web production and processing line shown in Figure 1, but with the difference that the winders are disposed machine-facing opposite that the direction of travel of the web 5 with the first winder 100 is machine direction and with the second 6 winder 200 anti-machine direction. The arrangement 7 according to the invention also enables this kind of lay-out, because the arrangement arrangement of the machine reels 8 according to the invention allows the machine reels and the reel shafts to be moved very flexibly both in terms of path 9 and timing and order. In particular, Figure 3 illustrates how the present invention can reduce the space requirement for a machine roll processing arrangement for a fiber web production and / or processing line. Here, the spindle / machine roll stores 55 are narrower than the spindle length. The stocking roll shafts and / or machine rolls are positioned at an angle at right angles to the center line 12 of the fiber web machine 15, so that the storage area can be utilized efficiently in storage. The lifting device further comprises means 330 for rotating the lifting device horizontally relative to the beam, which allows the machine roll and / or winding shaft to be transported, picked up and released at an arbitrary angle relative to the machine direction.

Fig. 4 schematically illustrates a fiber web production and processing line 10 according to another embodiment, which again essentially corresponds to the structure and 10 of the fiber web production and processing line shown in Fig. 1, except that the winders are arranged in a machine direction so that The direction of travel of both the first winder 100 and the second winder 200 is machine direction. The security area generally, and in conjunction with each process unit, is preferably arranged such that the auto-crane can move machine reels and / or rul-axes between process units at least two different paths within the security area, using different security areas. This ensures that the process runs smoothly and yet it is possible for each process unit to perform the necessary manual operations. Because machine rolls and / or reel shafts can also be moved lengthwise, a relatively small area is required. Fig. 4 shows safety zones on either side of the centerline of the fiber web production and / or processing line 20 extending from the machine direction from the roll to the two winders, so that the machine winding and / or winding axis traffic to the second winder 200 can easily circumvent the first winder 100. 1 2 3 4 5 6 7 8 9 10 11

Fig. 5 schematically shows the arrangement of the machine rolls 2 of the fiber web production and processing line 10 according to another embodiment, shown in cross section 3. The operation of this generally corresponds to that of Figures 1-4. In Figure 5, the machine room basement 510 and the machine platform 500 are shown. In this embodiment, the reel 20 is arranged substantially on the machine plane 500 and is delimited by fence 65 to a security area 60. The figure illustrates in particular how effectively utilize data center space. Here, the winding shaft 8 / machine roll storage 55 is realized in an upright design that extends from the basement 510 above the machine level 9,500. In this embodiment, the lowest location for the roller shaft / machine roll storage 55 is the rails extending in connection with the winder 11100 located in the basement. Also according to the invention, the winders are arranged within the safety zone 15 60. In the arrangement, the second winder 200 is disposed at the machine level above the winder located in the basement.

Figure 6 schematically illustrates a fiber web production and processing line 10 according to another embodiment, which again essentially corresponds to the structure and function of the fiber web production and processing line shown in Figure 1, except that line 10 comprises only one winder 100 and a winder. Further, between the 100 and the retractor, substantially the center line 12 has a machine roll unloading and preparation site 80 provided with a pulper opening 85 in the machine plane for unloading the web 10 to a pulper or scrap conveyor if necessary. The safety area generally, and in conjunction with each process unit, is preferably arranged such that the auto-crane can move machine rolls and / or winding shafts between the process units by at least two different routes within the safety area, using different security areas. Figure 6 shows the security areas on either side of the centerline of the fiber web production and / or processing line. In addition, a separate security area is provided for each process unit. The corridor area 60.1 between the retractor 20 and the machine roll unloading and preparation site 80 forms its own security area. Naturally, there may be several corridor areas and the security areas they form. 1

It should be noted that only some of the most preferred embodiments of the invention are described above. Subprocesses and process equipment that may be within the scope of the processing system of the invention include: winding / unwinding / winding, longitudinal cutting / calendering, calendering / calendering, winding shaft emptying, machine roll preparation, storing of roll shafts and machine rolls, and fiber web. sampling / inspection. Thus, it is to be understood that the invention is not limited to the above embodiments, but can be applied in many ways within the scope defined by the appended claims. The features disclosed in connection with the various embodiments may also be used in conjunction with the other embodiments of the basic idea of the invention and / or combine different entities from the features disclosed, if desired and the technical possibilities for doing so exist.
