Description
Technical field
The present invention relates to a kind of curtain type applicator that is used on paper web, board web or other fiber material web of operation, applying coating; Said curtain type applicator has and is arranged in fiber material web top and applies head to export the coating media of at least a form for fluid to the paste of one or more layers heavy curtain corresponding to the curtain type of fiber material web width at least; Said heavy curtain is basically owing to gravity drops on the fiber material web; Wherein, Be its descent path of guiding heavy curtain process, just guide heavy curtain, at least one lateral margin of heavy curtain, be provided with the heavy curtain retainer in the separation edge (Abrisskante) that applies head with between the surface of the fiber material web that moves along the longitudinal direction below the coating head; In addition, said curtain type applicator has coating media feeder and boundary layer of air removal device.
Background technology
This type of curtain type applicator is by known among DE 102 32 949A1.The heavy curtain that suggestion is stable through the heavy curtain retainer or guiding is exported by the curtain type applicator in the document.
Use the exportable single coating media layer of known curtain type applicator and can export a plurality of layers simultaneously.The implementation type that also has the curtain type applicator of heavy curtain retainer (being called the edge lath at this) is described and diagram in disclosed DE102008040409 subsequently etc.This form of implementation shown in Figure 1 is also referred to as " sliding mould " in professional circles, i.e. the sliding layer nozzle.This so-called sliding layer nozzle contains at least two coating medias comb, coating media respectively from said coating media comb through on the sliding surface of supplying with the gap and arriving the sliding layer nozzle, said supply gap again respectively transition be the outlet nozzle of slit-shaped.The coating media that the outlet nozzle of arranging before and after in parallel with each other comes out is stacked up and down at this.This multilayer dielectricity breaks away from being called separation edge or being also referred to as on the edge that breaks away from line of nozzle, and drops on as the multilayer heavy curtain or on the guide plate that connects in the middle of dropping at first down or directly on the surface of fiber material web of matrix or operation of coating to be applied.The edge lath can be on the width of heavy curtain promptly in the horizontal direction adjusted of applicator.But the also known other form of implementation that applies head, wherein, a plurality of gap nozzles that are used to produce the gap nozzle that individual layer applies or are used to export multilayer point to downwards below the fiber material web of operation.Separation edge forms by one in the gap nozzle antelabium at this, or in variant, is formed by the end that is arranged in the sliding surface between delivery nozzle and pairing face or the fiber material web.For this reason, with reference to mentioned DE102008040409, wherein, in this Fig. 3, illustrate and described the individual layer coating.In addition, reference is disclosed DE102007000778 subsequently, and it is multilayer coated wherein to disclose curtain type.Also in one invention of back, advised the curtain type retainer, said heavy curtain retainer can be gone up motion in machine direction (longitudinal direction).
Smearing in (it is multilayer coated both to have comprised that individual layer also comprises) of use curtain type applicator (Curtain Coater), the coating width can be smaller or equal to the width of fiber material web, and this is called " in the width of cloth (inboard) " method of operation.And in so-called " the ultra width of cloth (overboard) " method of operation, the heavy curtain width is greater than the width of fiber material web.
Especially, in the method for operation, as disclosed in first described publication, the curtain type applicator is necessary in the width of cloth.This heavy curtain retainer is the heavy curtain of about 200mm to the fiber material web guiding greater than length, until approaching said fiber material web.
Usually be arranged in pairs from heavy curtain retainer well known in the prior art.At this, a heavy curtain retainer is positioned on the so-called guide side, and a heavy curtain retainer is positioned on the so-called driving side of painting machine.These heavy curtain retainers each be arranged on the parts of painting machine regularly and rigidly or the parts of curtain type applicator (for example applying head, feeder or boundary layer of air removal device) on.Though these layouts are stable, shortcoming is that these parts groups always only can all be moved, and this is very expensive.For example when introducing new fiber material web, must move the heavy curtain retainer.
Touch the heavy curtain retainer unintentionally through regular meeting, this makes the other parts of heavy curtain retainer or related assembly to be damaged.For example, the cylinder of possibility " parcel " guiding or the supporting width of cloth when the unexpected fracture of the width of cloth, the feasible heavy curtain retainer that also is in same position is hindered or is damaged.This possibly be possible in cleaning or maintenance work also.At this, for example cleaning or attending device possibly bump against the heavy curtain retainer, and heavy curtain retainer or equipment itself are damaged.
Summary of the invention
Therefore, technical problem to be solved by this invention provides a kind of curtain type applicator that no longer has the shortcoming of prior art.
This technical problem of the present invention uses the curtain type applicator of the characteristic that has claim 1 to solve.
Suggestion makes the heavy curtain retainer be arranged in movingly on the parts of painting machine or curtain type applicator according to the present invention.This movable property guarantees to remain to its position at least one heavy curtain retainer of applicator run duration (preferably on the guide side at painting machine He on the driving side heavy curtain retainer being arranged respectively), but also can leave and/or be in its run location once more.
Because there is the good protection to the heavy curtain retainer in this movable property of heavy curtain retainer when the motion that is caused by external force.Therefore, this power can not occur according to plan, just only accidental the appearance.As an example be that the width of cloth separates or the guide roller of the guiding width of cloth or the so-called parcel of idler pulley.The width of cloth layer of this foundation can with arrange movingly-the heavy curtain retainer that for example dangles movingly pressed off in a predefined manner.In the prior art, possibly be damaged at this heavy curtain retainer or its fixture or the parts that connect above that.
The chance motion of heavy curtain retainer also possibly take place when maintenance or cleaning applicator.At this, for example also possibly make the swing of heavy curtain retainer, and not make heavy curtain retainer or equipment be damaged with undesigned contact of cleaning device.In addition, the personnel that directly rest on painting machine or curtain type applicator place are protected and are not clipped between the heavy curtain retainer and the width of cloth or between heavy curtain retainer and the cylinder because as said, can realize the heavy curtain retainer fast with swing reliably or move.
The heavy curtain retainer also can move wittingly.This particularly is incorporated into the new width of cloth situation in the machine or waits for the situation of joint through (Splicedurchgang).At this, advantageously the heavy curtain retainer is not in run location, and only interim motion process.
Therefore the movable layout of heavy curtain retainer on the parts of painting machine or applicator make and can at least one heavy curtain retainer strictly be located to be used to smear operation; And can guarantee the coating media heavy curtain from separation edge to matching the reliable guiding of face, but can move out rapidly when needed.Usually, described pairing face is paper web, board web or other fiber material web.But when applying indirectly, pairing face also can be the surface that applies cylinder or continuous web.
In favourable mode, the bearing support of painting machine (being also referred to as framework) is parts of having arranged the heavy curtain retainer on it movingly.
Another possibility is that also the coating head that the curtain type applicator is provided is as the said parts that are used for the movable layout of at least one heavy curtain retainer.In suitable manner, movable layout can be simply to dangle.
Said parts are used for the existing boundary layer of air removal device that movable other possibility of arranging also can be to use coating media feeder (so-called starting groove) or use the curtain type applicator.
Can make the heavy curtain retainer pass through movable joint or hinge is connected with above-mentioned parts within the scope of the invention for being rotated motion.With this, can realize and the motion in the same way of width of cloth traffic direction.Also but direction is outside but rotatablely move, and promptly leaves from machine center or along the horizontal direction of machine.
But the other motion possibility of at least one heavy curtain retainer is to make the translational motion of heavy curtain retainer.At this, for example outside linear running is possible.For this reason, for example consider that slide bushing or straight line guiding piece are as parts.
In addition, aggregate motion also is possible.At this, preferably contain the motion of the component on width of cloth traffic direction, because this helps the activation through external force.
Advantageously, the heavy curtain retainer can be regulated laterally or on the width moving at heavy curtain for specification extraly.
Specification is regulated width that means heavy curtain usually and the width that therefore means coated deielectric-coating.For this reason, can consider the rectilinear motion described.The heavy curtain retainer can be arranged and when putting back, can set other specification with identical motion.Alternatively, specification is regulated also and can be passed through other motion realization separately.
, specification only needs the heavy curtain retainer is staggered in regulating.Alternatively, also can nozzle edge element on the sliding layer nozzle or the nozzle space limiter that also will be arranged in the nozzle slit together be staggered simultaneously.Through all edge members that stagger simultaneously, can realize that the nothing of coating media refluxes and break-even coating.
Also allow to make the heavy curtain retainer can be locked at its each residing position according to solution of the present invention.Therefore, for example provide form fit to connect, promptly hooked related position.Hook and to realize mechanically as said that promptly form fit ground is realized.But also can realize keeping through magnetic force or negative pressure.Locking can manually be controlled or Long-distance Control, and release once more when return movement.
The locking of arranging the position at the heavy curtain retainer is significant when introducing the new width of cloth or carry out cleaning, maintenance or the work of setting usually.
For example simple retainer is realized in the position (run location) that swings at the heavy curtain retainer, and said retainer guarantees repeatably correctly location.By the coating media that flows or normal operation power that boundary layer of air caused because retainer and the heavy curtain retainer is removed.As the bigger power that for example when the width of cloth separates, occurs causes a kind of predetermined arranging.Therefore the heavy curtain retainer keeps not being damaged and can coming into operation.
At least one heavy curtain retainer can manually move.For this reason, can before introducing the width of cloth, it be opened and after introducing the width of cloth, be placed on run location at this.
As manually moving substituting of heavy curtain retainer, also can realize moving of heavy curtain retainer through adjustment means.As adjustment means, for example can use pneumatic linear actuator, pivot drive or other known adjustment means own.This variant is specially suitable when introducing the width of cloth.Therefore the heavy curtain retainer can open before introducing the width of cloth and after introducing the width of cloth, be placed in run location at this.
The heavy curtain retainer also can the automated manner motion.With this, can any position on painting machine detect when the width of cloth separates and make the heavy curtain retainer arrange very soon and very reliably.This arranges in the beginning or ending phase that also is appropriate to very much the process of smearing automatically.
What also should mention is that at least one heavy curtain retainer can be automatically or from horizontal reset.This can for example realize through spring force.When for example when the width of cloth extrudes the heavy curtain retainer through external force when run location separates, need only external force and act on no longer then that the heavy curtain retainer can be returned to its run location voluntarily.
What also should replenish is, but at least one heavy curtain retainer contact separation edge in path between cross-over connection separation edge and pairing face or the fiber material web.But the top edge of heavy curtain retainer and the distance between the separation edge also are possible, for example the distance between 0 to 30mm.In addition, the distance between the lower limb of heavy curtain retainer and the pairing face (or fiber material web) also is possible, and wherein this distance for example is 0 to 2mm.
The applicator according to the present invention that has at least one heavy curtain retainer of arranging movingly can be used as known sliding layer nozzle and gap nozzle or twin-jet nozzle or duplex nozzel.Can produce the heavy curtain that is configured to single or multiple lift with this applicator.Width with the comparable fiber material web of the producible heavy curtain of related applicator narrower (type in the width of cloth), this is a preferred type at this, but also comparable fabric width wideer (ultra width of cloth type).
