Description
Technical field
The present invention relates to a kind of system that is used for the broadening fiber web; Also relate to a kind of be used to control shift method that bar or edge strip shift and with the machine of this systems produce fiber web.
Background technology
The known particularly machine of paper web face, paper/paper sheet breadth or fabric web of preparation fiber web that in a large amount of the argumentation, relates to.After comprising, it connects cadre's so-called wet end.This fiber web passes through at least one fibrous face treatment facility along its fiber web guide path.The machine that is used for preparing and/or handles fiber web is in the machine startup of producing beginning and restarting after parking, usually transition zone to be separated from fiber web, and shift by the transfer equipment and/or the treatment facility of serial connection, wherein this transition zone gradually broadening to whole fiber web width.This class breadth is handled and not only is standardization program to paper machine but also to making board machine, has at least one head box, wet end, cadre and optional a plurality of follow-up processing workshop section.For forming or separating the described transition zone that is also referred to as marginal belt, known wide variety of equipment.These equipment for example are so-called band and remove equipment, water jet shearing equipment, laser shearing equipment etc.Collecting device is derived or be directed to thereafter to residue band that forms by separation process or remaining breadth particularly in the pond below the paper machine at separated part.Under high machine speed, guarantee that the requirement of breadth guiding is very high accurately.Under negative pressure, force this transition zone to enter the desired position,, at this moment should derive downwards usually by the residue breadth to continue that it is sent to guiding parts.
Even if for guaranteeing can also accurately lead described transition zone or marginal belt under very high machine speed, known have a large amount of measures.These measures are described among EP 1640497A2 and DE 102004048157 A1.
Press DE 102004048157A1, this equipment that is used for the dry-web face comprises guide device, this fiber web alternately leads with the drying of ventilative supporting strap by guide roller and heating in drying equipment, has the negative pressure that is formed on the opposed supporting strap side of fiber web in the fiber web district that this guide device moves and remove the district before drying.This negative pressure is removed the district and is removed the district by a plurality of single negative pressure and forms, and this each negative pressure is removed and distinguished and can control respectively, and the effect width transverse to total negative pressuren zone of breadth moving direction is variable thus.
By known a kind of equipment that breadth is torn or removed and therefore survey required new transfer that is used to survey among EP 1640497 A2.Provide and be designed for the equipment that detects dismounting and be for when the material for transfer breadth, particularly the dismounting to this transition zone or material web produces reaction when the width of this transfer amplifies.Set up at breadth thus, when broadening, can obtain and detect fast inefficacy especially automatically and restart breadth transfer and broadening.
Described solution, particularly a kind of way in back can be used for detecting the dismounting of this transfer bar or edge strip.But the problem that is produced of carrying secretly by the residue vertically hung scroll that can not estimate is uncontrollable, especially under the case of machines of operation fast during at the fiber web broadening regular meeting cause remaining breadth and stablized roller by first and carry secretly.Produce edge defect thus, this defective can cause the breadth completely on next drying to lose with the continuation conveying of breadth.This also causes long downtime usually and produces break period.
Summary of the invention
Therefore purpose of the present invention is, controls by the edge defect of carrying generation secretly of residue breadth reliably and avoids unnecessary causing to produce the downtime of interruption and restart the time.Should after shutdown, can carry out breadth in addition smoothly reliably and shift, after detecting breadth and tearing, should implement as early as possible to restart.
Purpose of the present invention is at first preparing fiber web by a kind of, particularly the system that is used for the broadening fiber web in the machine of paper web face, paper/paper sheet breadth or thin paper breadth realizes, this system comprises at least one separation equipment, this equipment is movably on the direction transverse to machine, and this fiber web is divided at least two branch breadths, i.e. first so-called edge strip or transfer bar and second so-called residue breadth.Breadth be will remain again and collecting device and/or pre-processing device will be transferred to.By the present invention, for controlling transfer process and shifting the edge defect that may occur on the bar, be provided for the stabilizing equipment of stable residue breadth, from transverse to machine direction, described stabilizing equipment is placed between the final position of the starting position of separation equipment and separation equipment at least.
Term " machine direction " and " transverse to machine direction " mainly are at the fiber web traffic direction.Machine direction is described the extension of the machine that is integrated with system of the present invention be used to prepare fiber web, this machine with the direction of the treatment facility respectively waiting to pass through promptly thus at fiber web earlier as the direction operation of fibrous suspension and back as fiber web.Therefore mean direction transverse to the direction of machine, usually corresponding to the width of the machine that is used to prepare fiber web transverse to fiber web.
Even if solution of the present invention also can be directed to collecting device and/or pre-processing device with the residue breadth reliably under high machine speed, avoid thus carrying secretly at the unfavorable of each direction.This fiber web particularly shifts bar and can be directed to next treatment facility safely, and avoids carrying the harmful shutdown that is produced secretly by residue breadth part unfavorable.Can cause downtime in a word and produce the decline of break period thus.
Fiber web is divided at least two branch breadths carries out with separation equipment, this separation equipment comprises at least one separating component.By this required original position that shifts bar or edge strip, can be divided at least two kinds basically may.The avris position of this edge strip or transfer bar belongs to this, and promptly this edge strip is formed by the side petiolarea of this fiber web.In this case, a separating component is just much of that.This separating component feature is the start bit that regards to fiber web, and it is installed to be corresponding to the wide lateral distance of required start edge bar with fiber web edge, side.In the case, approaching for being easy to, this separating component preferred disposition is in the guiding side of the machine that is used to prepare fiber web, and moves this separating component and realize in the driving side direction to the end position corresponding to the web of fiber face width at least, promptly realizes in the machine side that drive train is being installed.This start bit can be simultaneously corresponding to the bearing position of separating component.But from keeping in repair viewpoint and adapting to other boundary condition, this start bit can freely be transferred, and actual bearing position is in the outside of the web of fiber face width of guiding side.
Another may be that this transfer bar does not produce in the width at fiber web at the edge, promptly at the center or slightly eccentric basically the generation.In the case, dispose at least two separating components, its start bit on width or direct neighbor be positioned at the web of fiber face width or be each other corresponding to the required wide spacing of initial transfer bar.This separating component is to move from the direction of this start bit to the fiber web edge, and fiber web moves on, and produce to the preferred intermediate transfer bar that evenly amplifies of two directions, its condition always moves with the driving side direction and the guiding side direction of identical speed to machine for this separating component.The advantage of this solution is, based at the identical speed of each separating component and fiber web by the both sides broadening under the speed, shift bar can be obviously quickly broadening move on the whole fiber web width.At this moment it is less that the maximum of two residue breadths on the machine-wide direction that is produced extended size, and required for this reason stabilizing equipment also can be by small construction size and less power designs.So this solution also useful application in installation situation with little structure space.
The selection of used separator is not limited.Can use known devices as separation equipment or separating component.Under the simplest situation, can use so-called hydrojet, promptly be the separating component of exercisable nozzle-type, the liquid metal jet flow that this nozzle produces the directive fiber web is preferably water jet, this jet defibre breadth.This separating component can or be used for fluid operation from other process cycles of the machine for preparing fiber web with running water.Other possibility is the equipment such as the laser of application machine device such as cutting knife or clipper or contactless effect.
Mutual arrangement to separation equipment and stabilizing equipment has multiple possibility.Can consider to be series connection according to its function arrangement in system links to each other.By the required possibility that is directed to collecting device or pre-processing device, can provide the active region of separating component and stabilizing equipment according to following situation in the direction of machine:
A) overlapped or
B) spatially be separated from each other.
Situation a) under, in the separation of Disengagement zone, realized the stable and deflection of traffic direction of the residue breadth of this fiber web.But this scheme to edge strip and the fiber web that produces thus proceed to have proposed high requirement.
In the arrangement that is series connection before and after the space, it can be arranged by the adjacent but mode separately that also can spatially be in space.At this moment the lock out operation that is divided into edge strip and residue bar can not just take off the residue breadth simultaneously realizing under the situation of the closed guiding of fiber web before away from the stabilizing equipment active region under continuous tape loop or felt or corresponding the transmission.In the case, as in having wet end and cadre's machine scheme, at wet end or also can take off the residue breadth at cadre's initiating terminal.
Described stabilizing equipment has the active region of expanding at least on the subregion of fiber web width, preferably corresponding to the theoretical maximum residual width of the working width of separation equipment.Can support the whole residue breadth width that is directed in collecting device and/or the pre-processing system thus.For irrelevant with the mobile width of separation equipment and only support in esse residue breadth, this stabilizing equipment also can extend on whole web of fiber face width, at this moment regulating action district separately in all cases.For guaranteeing always to support fully the residue breadth, but preferably adapt to the active region step-less adjustment of this stabilizing equipment the width of this residue breadth.
For realizing that there are various possibilities in stabilizing equipment.It comprises at least a stabilizing means that is various formation.It under the simple scenario the so-called paper tinsel plate of configuration, this paper tinsel plate is formed by the slab parts of plate shape or broad, these parts are on machine-wide transverse to the traffic direction of fiber web and extend and from the guide direction of residue breadth oppositely, be a certain angle and be placed in residue breadth place.Between residue breadth and paper tinsel plate, be residue breadth direction and form the space.By the generation negative pressure of bleeding, this negative pressure attracts this residue breadth in facing the zone of paper tinsel plate in this space.Here this active region is determined by the paper tinsel plate width transverse to machine direction.Making its ineffective straightforward procedure is to realize by the whole paper tinsel plate of deflection, this deflection preferably around transverse to machine run direction or fiber web traffic direction by following realization, promptly for example this changes the orientation angle with respect to the residue breadth fully.For reaching this paper tinsel plate is activated or deexcitation, this paper tinsel plate can be divided into a plurality of minutes plates again.By a particularly advantageous scheme, this paper tinsel plate also can be made up of many single paper tinsel plate member, and the adjacent installation on the traffic direction transverse to fiber web of these each parts can be raised the paper tinsel plate member that forms each subregion when needs reduce the width of stable region.In addition, this paper tinsel plate or each paper tinsel plate member also can be in reverse to the machine direction slip.
By another expansion scheme, also configurable pumping equipment increases the swabbing action of paper tinsel plate, and this pumping equipment portion adds or randomly takes out to be received in and remains the gap that forms between breadth and the paper tinsel plate.The feature of this pumping equipment is that to have at least one its width be the suitable branch suction district of fixing or be preferred for and remain breadth that is adjustable suction district or many adjacent arrangements are arranged of width.For realizing almost is that continous mode is adaptive, this pumping equipment has many suction districts that are transverse to the adjacent arrangement of fiber web traffic direction, these many suction districts preferably but must not be that identical size, particularly width dimensions are all arranged and can be single and/or grouping and/or unite and control.Be each respective area configuration control device, particularly valve device for this reason.
Another alternative plan is to use a kind of to be static, promptly to have a pumping equipment that the device of fixed-site of the bearing-surface of fixed-site implements or implement with suction roll, relate to a kind of equipment that forms static suction district under the suction roll situation, the breathable band passes through this equipment to form bearing-surface.At this moment the configuration of this suction district makes its part guide path of prolonging this residue breadth operation.The advantage of implementing with suction roll is removable and cause remaining carrying secretly of breadth thus for this shell.
The suction district of promptly aspirating in paper tinsel plate and the pumping equipment in these two kinds of schemes can so form, promptly this pumping equipment provides at least a adjustability on width in addition and reaches the adjustability of at least a this active region thus being adjustable aspect the effective vacuum magnitude.Adjustability on the width can be continuously or segmentation implement, in addition can be on whole width or subregion implement.Under the subregion performance, this suction district is divided into a plurality of districts again.Each subregion all can be implemented arbitrarily.Particularly along seeing on the width of machine direction and the length, there is identical size in preferred each district.Each district can single control and/or several district or all districts control together.Preferably also can in a district, change pumping power in the part.In addition, can be single or activate or deexcitation by group in these districts.But by the wide and activity in district, the particularly controllability in each district also can almost be the width of the variation of best adaptive this residue breadth on the machine-wide of determining.The use of this equipment can be that the kind of central bars or edge strip is irrelevant with shifting that bar produces also, because should be than the simply kind and the mode deexcitation of district at center.In addition because the fiber web width is in a threshold value, can independent usability from what this kind equipment also was provided.
Another particularly advantageous scheme is to realize described stabilizing equipment with injection device.At this moment fluid so is applied to or directive residue breadth, promptly this fluid penetrates with the fibrous web surface that is arranged essentially parallel to this residue breadth as driving jet or driving the jet valance, and this this formed power of residue breadth reason is carried.At least one durection component is oriented to be parallel with required fiber web guide direction.
Described stabilizing equipment comprises that at least one has the injector part of certain effect width, preferably a plurality of single type injector elements transverse to the arrangement of fiber web traffic direction, and its each active region is overlapped.This injector effect produces by fluid jet or jet valance.Can adopt gas, water, steam or the preferred original air that just exists as fluid.At this moment produce jet.This jet can pass through valve, the ejaculation geometry of preferred fine tuning valve regulation its parameter, particularly issuing velocity, ejaculation cross section, bundle length, bundle etc.This beam preferably is and is parallel to or somewhat different than residue breadth traffic direction.This effect width is preferably adjustable, particularly should change synchronously with the broadening of this separating component by the effect width, promptly narrows down with the amplification of shifting bar.Each injector part can be through single, in groups or common or selectivity or control at random by the combination of these possibilities.
The concrete structure conversion of possibility to the single of described each suction district or injector district or control in groups is not described in further detail.The importantly realization of almost stepless adaptive basic principle of the active region of described stabilizing means and the width of residue breadth, the width of this residue breadth must be that the width increase with this transfer bar changes, and particularly reduce.
At the machine that is used for preparing fiber web, the transition region of described system preferred disposition between wet end and cadre.Can realize the separated component breadth at wet end, but since pass on closed in the district, on supporting strap for the guiding of this fiber web, this minute breadth in fact in dry section, particularly remove in the district and separate at first of drying.Also can imagine another possibility.Directly before being transferred to the cadre, realize or just can carry out as this separation at the press section of wet end.
At the preparation fiber web, particularly being used to control the method for the present invention that shifts bar or edge strip transfer in the machine of paper web face, paper/paper sheet breadth or fabric web is characterised in that, after fiber web being divided into transfer bar or edge strip and residue breadth, the guiding of this residue breadth is subjected to the stabilizing equipment support, and makes it forward the direction of collecting device to.Prevent carrying secretly of undesirable residue breadth thus.
Stable scope preferably can be treated so that only support this according to the width adjusting of residue breadth in the active region of this stabilizing equipment in fact.Tear (Bahnabriss) if detect breadth, then make and fiber web is divided into the separation equipment that at least two fens breadths promptly shift bar or edge strip and residue breadth activates, wherein comprise the size of the width of the formed residue breadth of a kind of indirect sign at least, and the residue breadth width of extrapolating in the stabilizing equipment scope reaches the width of regulating stabilizing equipment according to this.Detecting when reaching completely the breadth width, just make the stabilizing equipment deexcitation, if also do not do like this by shifting bar.Can respond breadth very fast with the method and tear, and reach fiber web enforcement again smoothly reliably within a short period of time.
