Show the operation parts 19 not having end plate in figure 2b.In this case, run parts 19 to be made up of blow box (Blaskasten).The horizontal direction that blow box has along fiber web production machine is arranged on air inlet side and the blow-out nozzle of giving vent to anger on side.The pocket of the vacuum distribution that high vacuum region is arranged near dry net by the horizontal direction producing machine along fiber web and normal vacuum separates, and makes this region by vacuum load by suction.Shown operation parts are designed to use at production period, and on this position, web covers dry net, and Leakage prevention enters in operation parts through dry net.
Also show blowning installation 23 in figure 2b, it is arranged in the derivation wedge-shaped part 21 formed by drying cylinder 16 and dry net 18, departs from for making to connect band 22.The end connecting band 22 can be made to depart from drying cylinder 16 by blowning installation, then follow dry net 18.Blowning installation is in running order during connecting web, when as shown in Figure 2 b, connects the end of band 22 by the first shown drying cylinder 16.Although there is such blowning installation, in the process connecting web, particularly on slewing rollers and in group and the transition position of group, still there will be problem.It mainly connects band and can not reliably be attached on dry net in the region of slewing rollers.
The utility model relates to a kind of method connecting web in drying section for producing machine at fiber web.In drying section, dry net 18 is alternately supported as singly to net traction by drying cylinder 16 and slewing rollers 17.In other words: in drying section, drying cylinder 16 and slewing rollers 17 alternately support dry net 18 for singly to net traction.In addition, the pocket 20 be made up of together with dry net 18 slewing rollers 17 and two drying cylinders 16 is by vacuum load.For this reason, be provided with in the pocket 20 limited by slewing rollers 17 and two drying cylinders 16 and run parts 19.When connecting web, the importing wedge-shaped part 26 formed by dry net 18 and slewing rollers 17 is also loaded the vacuum strengthened by blow air 24, and (Fig. 3 a).Therefore, be furnished with blowning installation 25 according to device of the present utility model, this blowning installation is arranged in the importing wedge-shaped part 26 formed by dry net 18 and slewing rollers 17, imports the vacuum in wedge-shaped part 26 in order to the strengthening when connecting web.According to the utility model, limit passage 27 (Fig. 3 b) explicitly with importing wedge-shaped part 26 and blow air 24 relative to slewing rollers 17, this passage points on the edge of machine direction at it and is sealed relative to slewing rollers 17.In other words: there is according to device of the present utility model the passage 27 being arranged in importing wedge-shaped part 26 and having flow surface 28 (Fig. 3 b), be provided with blowning installation 25 in the channels, and this passage has the potted component 29 along machine direction orientation, sealed relative to slewing rollers on its edge for making passage 27.
The advantage of technique scheme has a lot.Wherein topmost advantage is: the vacuum effect significantly strengthened can enter into very deeply import wedge-shaped part.Contribute to realizing this vacuum effect according to the passage 27 formed relative to slewing rollers 17 of the present utility model.Passage 27 is limited by flow surface 28 in the side contrary with slewing rollers 17, and blowing gas stream 24 points to this flow surface.At this, blow air can cause Venturi-effect (Venturi effect): air is extracted out by from importing wedge-shaped part, thus on its forefront, obtains significant vacuum effect in the initial part of passage, particularly.In addition, guide air blowing process at the seal of the edge upper limit routing of passage and prevent vacuum leak simultaneously.Again can strengthen the vacuum imported in wedge-shaped part thus.Principle shows the device comprised according to passage of the present utility model in figure 2b, and this device is fixed on and runs on parts 19.
Show more accurately in fig. 3 a according to device of the present utility model.At this, the rotation direction along slewing rollers 17 is additionally provided with the extension 30 (Fig. 3 b) towards dry net 18 opening on passage 27.Make vacuum effect deeper to enter thus to import in wedge-shaped part.In addition, present vacuum effect also extends on dry net 18 and also connects on band 22 through dry net arrival.Thus make to connect band and be fixed on dry net with tightening, or rather, connect band direct before problematic position on the time point as far as possible early, be namely fixed on dry net with tightening before dry net and slewing rollers meet.Import in wedge-shaped part because extension is deeply arranged on, therefore vacuum all can not be leaked in any direction now.Connect band to be all reliably attached on the surface of dry net on the whole route of slewing rollers, thus can reliably realize connecting web.
In addition, vacuum leak can also be prevented by making passage 27 also be sealed relative to dry net 18 on Some routes along machine direction.Or rather, the rotation direction along slewing rollers is observed, and the initial part of extension 30 is provided with the sealing surface 31 relative to dry net 18 horizontal orientation.Show abstractively in fig 3b according to device of the present utility model.At this, the rotation direction along slewing rollers 17 is also provided with towards the extension 30 of dry net 18 opening on passage 27.In practice, extension is made up of edge seal 31, and this edge seal had not only contacted slewing rollers but also the edge of contact drying net, and was also like this in practice.The above-mentioned sealing surface 31 extended between multiple edge seal 32 can also be seen in fig 3b.Therefore, the horizontal direction that sealing surface must produce machine with fiber web matches, but the longitudinal direction producing machine along fiber web also tool have the dimensions.Edge seal 32 shown in broken lines in fig 3b, its shape follows the curvature of slewing rollers 17.
In shown embodiment, flow surface 28 is formed by being bearing in the slab structure 33 run on parts 19.Can not re-use independent supporting structure thus, and flow surface can be precisely located on the position of needs.This slab structure is light and required installing space is little.Sheet material is also easy to be shaped.The device preferably comprising slab structure supports on its edge, at this, can realize fixing on the end running parts.Therefore, fixing and possible adjustment becomes and is more prone to.In embodiment shown in this, slab structure bends and is sized to: the relative distance of slab structure and slewing rollers is increased slightly in blowing direction.In addition, the edge of slab structure is bent upwards.The slab structure of rigidity can be obtained thus, and can edge seal 32 is arranged in slab structure 33, to obtain compact, stable structure.
Due to slab structure and edge seal structure in aggregates, therefore slab structure maintains interval relative to turning roll surface.Meanwhile, the size of the passage formed remains unchanged substantially.Blowning installation 25 in this slewing rollers side 17 orientation/opening towards slab structure 33, and has the air blowing cavity 34 that the whole width along passage 27 extends.Air blowing cavity is used for making forced air balanced, and has the hole of the slewing rollers side 17 pointing to slab structure 33.At this, the blowing gas stream 24 formed in passage 27 flows along flow surface 28 on the contrary with the rotation direction of slewing rollers 17.
Compressed air is introduced in air blowing cavity 34 by the equalizer line joint (Ausgleichsrohrstutzen) 35 (chain-dotted line) pointing to machine direction.Equalizer line joint 35 is connected on larger compressed air pipe joint 36, and compressed air pipe joint is connected in the compressed air system of fiber web production machine.Therefore, the structure height of device can remain on lower level, and compressed air pipe joint can be used for supporting plate-like structure and edge seal.According to Fig. 3 b, air blowing cavity 34 is spaced relative to slewing rollers 17.At this, air siphons away by blowing gas stream 24 in passage 27 together, and this suction extends through below air blowing cavity 34 until above-mentioned extension 30.Replace entering of air because sealing prevents, therefore on described position, form significant vacuum.This vacuum illustrates with besieged minus sign in fig 3b.Now, when connecting band and running on slewing rollers, connect band and after sealing surface, be subjected to strong vacuum action simultaneously, this vacuum effect makes to connect band and is attached to tightly on dry net.Have nothing to do with the gas permeability of dry net, also catch tightly in dry net inside reservation vacuum and connect band.That is, to connect on therefore band be attached to dry net surface at slewing rollers place and can not get loose from the surface of dry net, until follow-up importing wedge-shaped part or until follow-up be positioned at group and the grass-hopper of group transition position, connecting to realize web.
Show blowing gas stream 24 in fig. 3 a, its final leaving channel 27 enters and runs parts 19.At this, the rotation direction along slewing rollers 17 is seen, is also provided with scraper 37 in the front of passage 27, enters import wedge-shaped part 26 for preventing the boundary layer air be arranged on the surface of slewing rollers 17.Scraper 37 guides blowing gas stream to leave simultaneously and imports wedge-shaped part (second arrow 38).That is, the boundary layer air admission passage moved on the surface of slewing rollers can be prevented by scraper, thus make the blowing gas stream in passage interference-free, and a small amount of air can be utilized to produce vacuum effect.The interference to running parts will be reduced further thus.Can arrange air guide element before scraper edge, when there is not the flow path around scraper in this position, air guide element can guide the air-flow left from passage into side.
Utilize the vacuum effect formed according to device of the present utility model to be quite significant, even when to be designed to smooth roll be even non-absorption roller to slewing rollers, also can realize wireless web and connect.Therefore, wireless web can be converted to when not investing in expensive grooving roll or VAC roller to connect.But this device also can combine with VAC roller, more easily to guarantee that realizing web connects and improve web threading speed.
Produce strengthening vacuum by blow air in the utility model.This process that blows is easy to control, and required parts only need very little installing space.It should be noted that in addition and can realize suitable vacuum with low unexpected superpressure and little air-flow, be partly due to low and at edge side by the passage sealed.In practice, the flow surface of passage is such as 5mm-15mm relative to the distance on the surface of slewing rollers.Balanced chamber is even more near slewing rollers.Therefore, even if when needs prevent boundary layer air from entering importing wedge-shaped part, also blow air can be set to: blowing speeds is greater than the circumferential speed of the slewing rollers of relative motion.Therefore, blowing gas stream can leave from passage, and produces Venturi-effect at this.In the utility model, blowing gas stream 24 is formed by compressed air, and this compressed-air actuated pressure is 10kPa to 60kPa, is preferably 10kPa to 30kPa.Therefore, low beat all stress level can be utilized to realize suitable vacuum.Meanwhile, specific air consumption only has a few decaliter each second, and this is equivalent to traditional stripping and blows.Whether measurement result shows: realize the vacuum of 500Pa to 6000Pa and slewing rollers and whether rotate or connect band and be positioned on passage irrelevant.Therefore, this device can work at all conditions.Such as, by the blowing gas stream of 30kPa, can when without connecting band, static realize the vacuum of about 3000Pa, the vacuum of about 4600Pa can be realized when having and connecting band.When advancing with the speed of super snail for dry group, utilizing identical 30kPa blowing gas stream can realize the vacuum of about 2200Pa, the vacuum (without connecting band) of about 1800Pa can being realized when web speed is about 675m/min.Therefore, the vacuum level realized is higher than prior art to ten times.In addition, known by experimental measurement: the covering connecting band strengthens formed vacuum hardly.Therefore can have a small amount of air in practice through dry net, it is negligible on the impact of vacuum.That is, can realize suitable vacuum effect by blow air, this vacuum effect can make to connect band and at once be caught firmly.The rotation of slewing rollers does not also almost affect established vacuum, imports in wedge-shaped part because stoped boundary layer air to flow into.Therefore, utilize according to device of the present utility model can produce at short notice significantly stronger compared to prior art, in importing wedge-shaped part darker vacuum more remarkable in prior art, thus can guarantee that reliably realizing web connects under all conditions.
The width of passage can be such as 400mm-500mm, and the length of edge seal can be about 200mm, and thickness can be about 10mm.It is long that the region of no pressure be reinforced is about 30mm, and the rounding end of edge seal is below 200mm at a distance of the contact point between dry net and slewing rollers.
Can blowing function be closed after completing web and connecting, but the passage comprising seal will be retained.When connecting web, the vacuum of strengthening pulls dry net relative to the edge seal of sliding on the surface of slewing rollers simultaneously.Therefore, preferably use the seal being made or utilized teflon coating by teflon (Teflon), the wear-resisting and dry net that can not wear and tear of this seal.To reduce at the after load removing vacuum, dry net departs from from edge seal.Meanwhile, reduce relative to the load of slewing rollers.Thus, edge seal can remain intact for a long time, even and if passage is fixedly mounted on operation parts, dry net also can not be impaired.Preferably only use blowing function as required.
Such as when web connects beginning, air is such as only introduced into the dry group of the first two.Also do not need for the time being to strengthen vacuum, because the end connecting band just starts in other dry group.Along with the advance connecting band makes new dry group to be loaded again, correspondingly then close blowing function in the place connecting band and covered dry net.
Utilize according to method of the present utility model with according to device of the present utility model, even can utilize non-attraction when single net traction, smooth slewing rollers realize reliable web and connect.Utilize a small amount of air just can cause suitable vacuum, this vacuum can also extend into optimal depth and import in wedge-shaped part.Surprisingly can also in dry net " storage " vacuum, at this, although there is centrifugal force, connect band and still can reliably remain on the surface of dry net.
