Description

CLASSIFICATION

The This invention relates to fibrous web machines, such as paper machines. In particular, the invention relates to production plants of a paper web.

BACKGROUND OF THE INVENTION

As From the prior art, paper is used in machines which together form a paper production line that can be several hundred meters long. The current paper machines can annually over 450 Produce 000 tons of paper. The speed of a paper machine can over 2000 m / min and the paper web width over 11 meters.

In Paper production plants are becoming more and more continuous Process. The paper web in production The paper machine comes with a reel around a winding axis or rolled up a spool roll to a mother roll, the diameter of about 5 meters and their weight over 160 tons. The purpose of winding up is to plan make the finished paper web into a shape that is easier to handle is. With the arranged in a central machine line reel the continuous process of the paper machine interrupted for the first time and switched to a discontinuous operation. It is desirable, this periodic process with a possible good efficiency, so that the work already done was not done in vain.

The The path of a mother's role in paper production in full width and is up to over 100 km long, so they for the Customers of the paper mill cut into partial webs of suitable width and length and before leaving the paper mill on sleeves to so-called customer roles must be wound. This slitting and rolling up the Bahn finds, as is known from the prior art, in one appropriate, separate Machine, that is in a slitter, instead.

The Mother roll is unwound in the slitter, the wide web cut into several smaller partial webs in the cutting section, in the wrapping around roll cores, such as sleeves, too Customer roles are rolled up. When the customer roles are done, will the slitter stopped and the rollers, that is the so-called Roller set, removed from the machine. After that, the process is called Winding a new set of rollers continued. Repeat these steps periodically until the paper on the mother roll is used up which is followed by a change of parent role and the The process begins again with the winding of a new parent roll.

In the well-known high-speed paper production facilities can Maybe paper machine produce more paper than a single slitter can handle, being more than a slitter in the paper production line needed becomes. The slitters are in some embodiments in the direction of the machine line and in succession arranged at a certain distance from each other.

In the known space solutions of paper production plants, that is in the layout arrangements, The first slitter is typically called a so-called Inline slitter, that is, the slitter with the paper machine and the reel in a line, that is in the central machine line, is arranged. A second slitter is a so-called Offline tailor using the paper machine in a line the first slitter can be arranged. In both slitters are Customized roles, usually with roller conveyors first for packaging, for example in a roll wrapping machine and finally before shipped to the customer in a warehouse.

at the slitters in known paper machine lines the parent role usually with a hall crane to such Slitter brought, which does not have transport rails to the Paper machine is coupled, and down on the transport rails let that are typically arranged so that the height of the center the mother roll is about 2.5 meters from the bottom surface. As a minimum distance of Mother roll and the lower surface the parent roll, such as the bottom surface, typically becomes one Safety distance of 500 mm complied with. In versions, in which the reel of the paper machine and the slitter on transport rails are combined inline with each other, the Mother roll on the transport rails from reel to winder transported.

In the simplest embodiment, the parent role also directly with the hall crane be brought to the trolley, in particular then, when it comes to small mother roles.

As is known, the transport rails for the full parent rolls are formed from horizontal or sloping rails with their waiting stations. On the transport rails, the mother roll from one waiting station to the next transported to the unwinding station. The parent roll is transported from one waiting station to the next on horizontal transport rails by means of a transport device and on sloping transport rails by rolling by gravity and by stop and release mechanisms.

It It is known that an unwind station typically consists of a Abrollbock is formed, which supports the mother roll during unwinding. Of the The trolley includes a first trolley on the drive side and a second shuttle on the operator side. The ends of the Mother role are during the unwinding on these trolleys. At the Bollards are over Joints are attached to locking levers that keep the parent roll for the time being the rolling process is locked in place. The in the unwind station mother roll is coupled to a Bremsgenera tor, which acts as a drive device of the unwinder.

in the Generally, the tambour roller, that is, the winding axle, the after the unwinding is empty, either manually by lifting with the hall crane or automatically with the operating device of the spool roller from the unwinding station away. The operating device of the drum tambour consists of either vertical lifting devices or rotatable lifting arms as well from above return rails for empty Drum rolls. The empty or nearly empty sprocket roller is with the lifting device or the lifting arm on the return rails lifted, where there are usually several return station places. Typically, the return station (Tambourlager) above the unwinding or the cutting and Aufwickelpartie arranged. On the return rails The tambour roller is either using a transport device or by rolling by gravity and by means of stop and Release mechanisms are transported from one station to the next. The empty drum roll is from the return rails removed and with the hall crane on the reel of the paper machine brought. With inline winder the return rails can also be used directly connected to the bearing rails of the spool rollers of the retractor be, with the tambour roller directly from the cutting device be transferred to the reel can.

For full Mother rolls, partially full mother rolls and empty drum rolls In the area of the slitter several storage bins are necessary, so that unhindered continuity of the process can be. Such bins are following the refining of the production line of the fiber web known in the area of the retractor and slitter of the fiber web in the central machine line in the interstices of the Main devices of the production process, that is between the slitters, the unwinders of the slitter and the reel-up belonging to the paper machine or to the coater arranged. In the arrangement between said main devices extend the storage bins the mother rolls and the spool rolls the production plant of the Fibrous web. The devices for the production process of the Faserbahn a complex of facilities that takes up a lot of space. The known room solutions production facilities of a fibrous web entail high costs, when the machine room needs to be very long. As is known, sets a production facility requiring a lot of space for a fiber web high and expensive building investments ahead.

BRIEF DESCRIPTION OF THE FIGURES

The The invention will now be described by way of example with reference to the accompanying drawings described.

1 schematically shows a first embodiment of the invention.

2 schematically shows a second embodiment of the invention.

3 schematically shows an embodiment of the high-load bearing, which is intended for the storage of parent rolls and / or winding axes, in side view.

DETAILED DESCRIPTION

In The following description will be like parts with the same Reference signs marked. It should be noted that the figures shown not in a scale relationship but that they are more to serve, just the embodiments to make the invention more illustrative.

The in the 1 and 2 For example, a fiber web production line shown comprises a fiber web machine such as a paper machine 30 , as well as a reel along with this standing in a street 10 and at least one slitter. In the figures, the production plant is housed in a building, wherein the positions of the walls of the machine hall by way of example and by the reference numeral 50 are marked.

The area 50 Inside the walls of the building, using a tight arrangement of the main fixtures of the process, which allows the reel 10 , the dispensers 21A . 21B and the slitter 20A . 20B of the production plant, and by means of adequate storage of the parent rolls 12 and the winding axes 13 be minimized. More specifically, it is possible that the part 50 carrying the loads of the machine room of the building and that of transporting the parent rolls 12 and / or the winding axes 13 used means of transport, such as the load transport radius of a hall crane, which accounts for the largest part of the investment costs of a building, at least as regards the area of winding and slitting the paper production plant, can be arranged short and / or narrow.

Following the slitter cutting area of the machine hall 50 of the building is preferably laterally of the main devices of the process and / or preferably in the machine line above the machine line as comprehensive as possible storage capacity 18 . 18 ' . 43 for the mother roles 12 and the winding axes 13 which are not needed in the close and immediate context of the main devices of the production process, without compromising the reliability and flexibility of the production process. Preferably, at least one Hochla ger 18 . 18 ' for the mother roles 12 and / or the winding axes 13 arranged outside the immediate connection of the main devices of the production plant.

The tiered arrangement of storage bins (the use of a high-level warehouse) in parallel with the process devices in the machine line and / or besides this can except in the reel and the winder also in other process devices the production plant of the fiber web are applied. This can be for Example: a coater, off-line calenders, intermediate scrapers, reject stations, To be a cart and so on. The tieragenweise arrangement of the bins in parallel with the process devices in the machine line and above the main devices can autonomously without the tiered arrangement of storage areas side of the machine line accomplished become.

Depending on the paper production process, for example full paper rolls, half-full rolls, reject rolls or winding axes, depending on the type of paper to be produced, flexible storage bins may be necessary on a case-by-case basis. For example, flexible storage bins can be created with a raised support of the type presented herein, without obstruction to the formation of a passageway 50 ' . 51 ' for passenger and / or freight transport essentially below the high camp 18 . 18 ' display. For example, when rewinding, depending on the process and the tear sensitivity of the paper, half full master rolls can be made 12 arise that require a flexible storage space. In essence, by the location of the high camp, the transit routes 50 ' . 51 ' be formed. The expression "essentially" is intended to express the fact that, regardless of the possible support structures of the high-level bearing, which could somewhat narrow the passageway, it is quite possible to form a significant part of the space below the high-bay for the formation of a passageway 50 ' . 51 ' to use.

Storage capacity for parent rolls 12 and the winding axes 13 can be achieved by applying preferred embodiments of the high-level bearings shown below 18 . 18 ' and combining (for example 3 ) of the preferred embodiments are arranged to an appropriate extent such that a possibly necessary passageway 51 ' at the front 51 of the machine room 50 as well as a possibly necessary passageway 50 ' is not prevented on the side of the roll and roll cutting area, and preferably at the same time by a dense arrangement of the main devices and by arranging necessary for the parent rolls and / or winding axes storage locations elsewhere than in the interstices of the main devices a short production facility can be created That may be the use of a short machine hall 50 allows.

It should be noted that in some embodiments it may be due to the high camp 18 . 18 ' possible, transit routes 50 ' . 51 ' (see also 3 ) in different directions. As a first example of this are the longitudinal passageway 51 ' that by the in 1 illustrated high camp 18 the mother roles 12 to the front side 51 of the machine room 50 leads, and the transverse passageway 51 ' passing through the same high camp 18 leads, at the second slitter 20B called. As a second example, consider the longitudinal passageway 50 ' that by the in 2 illustrated high camp 18 ' the winding axes 13 leads, and the transverse passageway 50 ' passing through the same high camp 18 ' leads, at the reel-up 10 called.

1 schematically shows a first embodiment of the invention, wherein a high-level warehouse 18 for the mother roles 12 and a separate high camp 18 ' for the winding axes 13 is arranged. Of course, at the in 1 shown embodiment as high camp also a combined embodiment of a high camp 18 . 18 ' , as in 3 shown to be used where so well mother roles 12 as well as winding axes 13 can be stored. The parent roller bearing 18 can of course also winding axles 13 and the winding axis bearing 18 ' accommodate half full rolls / reject rolls with a sufficiently small diameter.

According to 1 is for a user and / or for freight transport, such as for goods and vehicles and means of transport, for example, forklifts, transport devices, personal lift or the like, as well as for the goods that are transported with it, a passageway 50 ' at the side of the paper production plant and a passageway 51 ' in the back part 51 of the machine room 50 necessary, whereby the formation of these passageways is made possible when the lowest point of the parent rolls 12 and the winding axes 13 in the high camps 18 . 18 ' to be placed, is arranged at a sufficient height and the space between the supporting support elements of the high camp for the passageway is sufficiently wide.

Those in the production plants of 1 and 2 produced customer roles 19 for example, along the with dashed lines 52 marked routes preferably with a slat conveyor from the actual machine room 50 out of the building.

1 shows a first production plant, the one reel 10 and a first slitter 20A and a second slitter 20B that includes with the paper machine 30 integrated in one line. The paper web W coming from the paper machine 30 in the reel 10 The paper machine is made using a roll cylinder around a winding axis and a drum 13 to a mother role 12 wound.

The reel 10 preferably in connection with the transport rails 40 a waiting station 15 for the mother role 12 , wherein the waiting station preferably a parent role 12 or, for example, if the flexibility or reliability of the process so requires, if necessary, multiple parent roles 12 can record. The bins between the reel 10 and the first slitter 20A instead of in the 1 and 2 shown transport rails 40 also be realized on bearing blocks. The reduced number of stored parent rolls 12 between the main devices, such as the reel-up 10 and the first slitter 20A , helps to shorten the overall length of the machine line. The finished mother roll 12 If necessary, it will leave the waiting station 15 the parent role, for example, with a hall crane on to the high camp 18 brought to the side of the central machine line. The mother role 12 can from the high camp 18 in the waiting station 15 be brought to the parent role or in a unwinding of a slitter of the production plant. Of course, mother roles are also possible 12 be stored in at least one such high camp, which is suitable for the inclusion of both parent rolls 12 as well as winding axes 13 suitable.

On the reel 10 there is a first unwinding station 21A a first slitter 20A , preferably over the transport rails 40 are connected. Following the first slitter 20A can if necessary a depot 42 for empty winding axes 13 be arranged, for example, above the transport rails 40 , preferably on the rails.

The second slitter 20B is as close as possible to the first slitter 20A provided for the dense arrangement of the main devices, so that the paper production plant in the longitudinal direction of the building takes up the shortest possible space. If necessary, between the first slitter 20A and the second slitter 20B a passageway for persons and / or goods traffic are arranged.

The second slitter 20B includes a second unwinding station 21B and the rolling blocks placed in it 41 for receiving the axes of the parent rolls 12 , Following the second unwinding station 21B If necessary, a collection warehouse for empty winding axles 13 to be ordered. Following the second unwinding station 21B For example, storage bins can also be used for parent rolls, whereby the bins can be realized on transport rails or storage blocks.

The slitter and reel stations 22A . 22B the slitter 20A . 20B and the handling of the in the slitter-winder 20A . 20B cut and rolled up customer rolls 19 will not be explained here. It should be noted that part of the first slitter 20A and / or a part of the second slitter 20B can be arranged below the machine level.

The winding axes 13 be from the first reeling station 21A and from the second reeling station 21B or from the possibly placed in connection with these Abhollagern the winding axes 13 preferably in the high camp 18 ' transported, the storage of winding axles 13 suitable is. It can also winding axles 13 be stored in such a high camp, which is suitable for receiving both parent rolls 12 as well as winding axes 13 suitable is. The partially unrolled parent rolls 12 and the winding axes 13 with roll cores can from the rolling stations in such a suitable high camp 18 . 18 ' be brought, which has sufficient carrying capacity and storage height to form a necessary passageway 50 ' . 51 ' for persons and / or vehicles and / or means of transport and / or goods. For example, the half-full mother roles 12 (also for example from the waiting station 15 the mother role 12 Semi-perfect parent rolls to be transported 12 ) preferably in the high camp 18 for parent rolls, and the winding axes 13 with roll cores are preferably in the high camp 18 ' brought for winding axles, which is preferably arranged lower from its storage height ago and with lower load capacity than the high-level warehouse 18 for the parent rolls, as for the winding axes 13 required space in the height direction is significantly smaller than that for the parent rolls 12 required space in the height direction and the winding axes 13 much easier than the mother roles 12 ,

2 shows a second embodiment of a production plant, wherein the placement and the function of the main devices relating to the above description, reference is made. The second production plant has only one (similar to the under 1 explained) high camp 18 ' for empty winding axes 13 on. The high camp 18 ' the winding axes 13 is the side of the actual machine line next to the reel 10 arranged, being a passageway 50 ' for a user and / or for freight transport such as forklift, person lift or the like laterally of Paper production plant is formed when the lowest point in this high-level warehouse 18 ' placed winding axles 13 is sufficiently high and the space between the support elements that carry the high camp, wide enough for the passageway 50 is. Of course, according to the execution 2 as high camp also a combined embodiment of a high camp 18 . 18 ' according to the in 3 in which are shown both parent rolls 12 as well as winding axes 13 can be stored.

The warehouse 43 according to 2 for full and half full mother roles 12 is for example on rails or axles 44 near the back wall of the machine room 50 arranged near the ground surface, as in the case of 2 no important passage connection in the rear part 51 of the machine room 50 needs to be arranged, with the parent rolls 12 So close to the ground do not represent a passage obstacle. The warehouse 43 to 2 is the side of the actual machine line next to the second slitter 20B arranged.

In case of 2 can the machine room 50 Preferably be realized particularly short, since the main devices of the production process, that is, the retractor 10 , the unwind stations 21A . 21B and the slitter 20A . 20B , are arranged very densely, provided only with a minimum amount of storage spaces for parent rolls 12 and winding axes 13 necessary for the process, in the intermediate rooms or in direct connection with the main facilities.

It is recommended to have a number of parent rolls tolerated by the production process 12 and / or winding axes 13 outside the immediate vicinity of the main devices of the production plant, in particular the interstices of the main devices to arrange, so that a space solution is created, which takes as little space in the longitudinal direction of the building as possible. Preferably, in the high camp, the distance of the lowest point of the parent rolls 12 to the level of the passageway and / or the height of the lowest point of the winding axes 13 from level of the passageway arranged so that the formation of the passageway 50 ' . 51 ' which is necessary for a user and for the freight, is not hindered by the location of the high camp, regardless of where the high camp is located. According to some particularly preferred embodiments, at least one high-level bearing 18 . 18 ' for storage of parent rolls 12 and / or winding axes 13 arranged laterally of the central machine line.

According to some embodiments of the production plant, the high-level warehouse 18 . 18 ' in the central machine line, preferably above the devices placed in the machine line, or preferably above the parent rolls placed in the machine line 12 arranged.

The high camp located in the central machine street 18 . 18 ' can also be in the area between the reeling station 10 and the first unwind station 21A be arranged as in the 2 illustrated second embodiment of the production plant. It is recommended, at least at the reeling station 10 of the retractor and at the first unwind station 21A of the first slitter 20A to arrange a working area sufficient for transportation of the hall crane, not in the immediate vicinity of the high camp 18 . 18 ' lies. In the example case, the maximum height of the high-level warehouse above the machine line is moving 18 . 18 ' calculated on the order of about 7 meters from the machine level, if in the example a parent role 12 with a diameter of 4 meters is used. The height 30 The paper machine can be just as high in the press section, for example, which is why at a maximum height of the high-level warehouse 18 . 18 ' of 7 meters the access with the hall crane is realistically guaranteed without having to increase the height of the machine hall or the hall crane.

Regarding the locations and the operational applications of an in 3 shown in side view, preferred high camp 18 . 18 ' is based on the above description of 1 and 2 and to the claims. It should be stressed, however, that this is the description of 3 then, merely an example construction for the realization of a high camp is and that the high camp in terms of constructions, the number of storage bins, the types of storage bins, the locations of the structures of the storage bins, and so on, can also be configured differently. The high camp 18 . 18 ' from 3 includes below the parent rolls 12 and / or the winding axes 13 a minimum passage height L, which is a passageway 50 ' . 51 ' for passenger and freight traffic through the location of the high camp 18 . 18 ' allows. In some embodiments, it is through the high camp 18 . 18 ' possible, transit routes 50 ' . 51 ' to arrange in different directions, for example, a through gangway in the axial direction of the parent rolls and / or winding axles to be stored, or a passage leading transversely to this passage.
