The present invention relates to a kind of method and a kind of equipment, be used for coating dispersion thing on the web that flows, especially be used to indicate in order to produce, on web shape parting material, being coated with alite paste from adhesive type label, sticking film band and disperseing thing of explanation or decorative purpose, or in order to produce waterproofing packing material barrier-coating on web shape stock.
Production be used for that article are decorated or indicate from adhesive type paper tape or film band the time, in the known manner alite paste is disperseed thing to be coated on the web shape parting material, parting material then with cladding material that maybe will print that prints or cover film gummed.Preferably be coated on acrylates in the aqueous solution as alite paste, when tearing parting material for example behind the paper or film of silication, alite paste is adhesively stayed on the cover film, thereby cover film can be sticked on the article when using afterwards.
In order to produce the waterproofing packing material, the known barrier layer that on web shape stock, is coated with waterproof and vapor-proof.The plastic sheeting that uses paper web or the paperboard width of cloth or make as stock with PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), OPP (oriented polypropylene (OPP)) etc.Preferably be coated with the dispersion thing that contains PVDC (polyvinylidene chloride) for the barrier layer, wherein can add additional pigment.If the barrier layer is coated on the plastic sheeting as stock, then require a kind of binding agent of coating on stock in advance.
For coating alite paste on web disperses thing or the known use applicator roll in barrier layer, when web speed is up to about 500m/min applying implenent has the desired coating weight of desired uniform coating but they are only had the ability.
Therefore the purpose of this invention is to provide a kind of method and a kind of equipment, be used for coating dispersion thing on the web that flows, this method and apparatus can reach 100g/m above coating quantity under the situation of 500m/min in web speed
2Coating very uniformly.
This purpose reaches by the feature of claim 1 or claim 10.
It is preferred thereby be particularly advantageous design that dependent claims comprises the present invention.
In that the described dispersion thing journey that falls forms a curtain with enough uniformitys between 20mm and 500mm the time by claim 2, its guarantees coating equably.In order to be designed to adjustable for height by claim 11 slit injector according to the dispersion thing that is adopted and the desired coating weight adjustment that the is used for noiseless and even coating journey that falls.
Disperse thing at 5g/m
2With 100g/m
2Between wet coating can be by method of the present invention by being coated with especially equably by equipment of the present invention.Proved already that particularly advantageous was at 20g/m
2With 50g/m
2Between scope in.
Especially when the moisture dispersion thing of coating advantageously, the width of the curtain of free-falling is designed to the width (claim 4, claim 17) less than web.Narrower curtain causes uncoated edge, and thereby reduces to send out wrinkle or be laminated to dorsal part and the danger such as machine part in pollution downstream in the water intrusion edge and at drier inward flange subsequently.Under the situation of pasting coating, come from the reason of technology, uncoated edge is necessary.
Because bubble can cause that uncoated place is arranged when coating disperseed thing in the curtain of free-falling on web, the dispersion thing must degasification the most up hill and dale.By means of being undertaken by the described equipment of claim 24, this can make and control the influence that the amount of importing slit injector is not subjected to degasification in order to adjust coating weight in a circulation that separates with coating in the degasification that disperses thing by claim 5.

Fig. 5 disperses the change system figure of thing degasification.
The equipment of representing among Fig. 1 is used for the dispersion of the alite paste in painting solution thing (for example acrylates) on silication paper web 1.Because its favourable characteristic, other disperse things (for example propylene lacquer) also to be used on paper, plastic sheeting or the thin metal tape coating by equipment of the present invention.
Certain height is equipped with slewing rollers 2 in the frame of coating apparatus, and the web of importing from below 1 is diverted roller 2 and turns to the back to acutangulate extension obliquely along level (as in this embodiment) or with horizontal plane.Above the slewing rollers 2 and thereby zone above web 1 in, hang a slit injector 3 that extends transverse to the web flow direction in the frame.Below slit injector, web 1 is bearing in its downside ground along its whole width supported part and flows, and supporting member guarantees to have the web flow condition of accurate regulation when coating.In the equipment of pressing Fig. 1 and 3, slewing rollers 2 play supporting member simultaneously.
Among slit injector 3 and the figure not the dispersion thing input unit of expression is connected, at its downside one slot-shaped mouth is arranged, disperse thing from then on mouthful to discharge and form the curtain of a free-falling, act until dropping on the web surface.The gap width of nozzle 3 preferably less than the width of web 1, does not have the web edge that disperses thing so that leave after coating.Be suspended between two vertical section bars 4 to slit injector 3 adjustable height,, and thereby adjusted the journey that falls of disperseing thing so that can adjust slit outlet distance from web 1.The column 4 that has slit injector 3 can be along web flow direction and being bearing in two siding tracks 5 with predicting the horizontal movement of width of cloth flow direction, and siding track is predicted width of cloth flow direction (among Fig. 1 left) and extended in slewing rollers 2 region in front always.Therefore slit injector 3 can move in the preceding zone of slewing rollers 2 crestal lines always.So its discharge slit is in the top of blow tank 6, before blow tank is directly arranged in slewing rollers 2.
Preferably establish additional supporting member from slit injector 3 less than the distance of 1m along the web flow direction, the downside of horizontally extending web 1 is bearing on these supporting members.In pressing the equipment of Fig. 3, three rollers 7,8,9 that constitute roller-way are supporting web 1.Preferably not only below slit injector 3 but also in its back, use some fixing members in order to support web, and when web is broken, disperseed thing just can not throw away.Thereby pollute equipment when avoiding web to break.
These fixing members preferably are made of fixing hollow body 37 as shown in Figure 4, and it faces the ventilative material manufacturing of wall 38 usefulness of web 1.Hollow body 37 is connected with the compressed air input unit, and an air cushion is discharged and formed to compressed air between web 1 and wall 38 by porous wall 38, and web 1 does not have frictionally slip on air cushion.Make the appropriate especially material of porous wall 38 and proved a kind of pore size less than the porous thermosetting plastics of 500 μ m and the composite of aluminium.Pore size is preferably between 10 μ m to the 100 μ m.Compressed-air actuated loss is very little in this design, and web 1 slides on the air cushion of a thickness less than 1mm.Fixed support with porous circle wall 38 also has the advantage of another automated cleaning.Owing to discharge compressed air, from being designed to slightly crooked or tilting surface is led away the dispersion thing that knocks and can adhesively do not stayed on the surface.
Boundary's wall 38 is preferably designed as and forms a more or less protruding curved guide face, and wherein the axis of flexure plane extends transverse to the web flow direction.So backing roll 2 also is preferably designed as the cylinder of fixed-site, its outer surface is made up of the section of cylinder hull shape in the zone of being twined by web 1, and these sections are made with porous material.Therefore web 1 can be guided very imperturbably in all positions that it is worked.
In its operating position shown in Figure 1, in web supporting member ( roller 7,8,9, member 38) zone, establish the member that siphons away the dispersion thing in web 1 each marginal zone in slit injector 3 back.Every in this embodiment one slide rail 5 the insides are equipped with one laterally along the marginal zone with along highly orientable suction nozzle with battery unit 10, and it is connected with a suction tube that is used to siphon away the dispersion thing.In order accurately to adjust the vertical range with web 1, suction nozzle with battery unit 10 is positioned at the top of backing roll 8 exactly as shown in Figure 3.
After last backing roll 9, another backing roll 11 of web 1 guiding, it play a part one can towards lateral movement on the web 1 and from then on the scraper 12 removed of upside join roller.Scraper 12 laterally extends along the web width.It is fixed on one along on the support that is supporting pivotally 13 of working width extension.Support 13 is in each longitudinal side of equipment is contained in a bearing 14 that is fixed on the equipment rack.Scraper 12 realizes that by means of piston-cylinder assembly 37 latter is fixed on the bearing 14 on the one hand, is fixed on the other hand on the support 13 towards web 1 and the gyration of leaving web.In order to remove the dispersion thing that is scraped by scraper 12, before scraper, establish aspirator along the web flow direction.This aspirator preferably is suspended on the bearing 14 equally and is included in the breastwork 15 of back, and it forms a suction chamber towards web 1 opening with scraper 12, and unnecessary dispersion thing is from being sucked away here.
Because the curtain 39 of free-falling is because surface tension is tended to shrink in its edge, so establish near the guide 41 that extends to the web 1 downwards at the two ends in slit injector 3 slits 40 always, their resist the contraction to edge.Fig. 2 has represented to have the nozzle 3 best forms of implementation of guide 41: at each place of slit injector 3 both sides adjacent slit outlet 40 other each fix a guide 41, it is designed to the plane in its inboard 42 towards curtain 39.Inner surface 42 extends towards curtain central authorities angle between 0 ° and 10 ° of inclination to the direction of web 1 from nozzle 3.
The lower limb that each guide 41 constitutes inner surfaces 42 terminals is preferably designed as precipitous seamed edge 47, and the edge that makes curtain 39 flows along the direction of regulation and outwards do not do undesirable deflection and leave guide 41.
Above slit outlet 40, each guide 41 has a through hole, and it is as the conveyance conduit 43 of input auxiliary liquid on inner surface 42.Adopt the capillary liquid of a kind of minimizing as auxiliary liquid, for example water, contain the water of spreading agent or contain the water of the dispersion thing of dilute with water.
Conveyance conduit 43 feeds the top of the transfer passage 44 of an about 20mm length of arranging inside with extending vertically downward above slit outlet 40, the outlet of transfer passage 44 directly is in slit outlet 40 sides at the place height of the slit of nozzle 3 outlet 40.This transfer passage 44 structurally can be realized in such a way simply, promptly, the vertical left-handed groove in a through hole 43 of the location of slit injector 3 processing in guide 41 inner surfaces 42, it is sealed by this sidewall when guide 41 is fixed on nozzle 3 sidewalls.
Importantly, the auxiliary fluid of importing guide 41 in the above and flowing down along inner surface 42, when with the EDGE CONTACT of curtain 39, for example after the height of slit outlet 40 has left transfer passage 44, flowing of perpendicular downward direction arranged, and the speed that flows is identical from the velocity of discharge size of nozzle 3 with the dispersion thing at least.Guarantee like this,, the delay at the curtain edge of curtain 39 stability can not occur influencing at guide 41 places with respect to the falling speed of curtain 39 at central area.It is fully wetting by auxiliary fluid that inner surface 42 is designed to make it.The cross force that therefore expansion is arranged in the edge action of curtain 39 can be owing to the delay falling speed or owing to the lateral flow in edge influences its stability.
In each marginal zone of curtain, respectively establish a separator 45 between guide 41 downsides and the web 1, it outside in extends in the scope of web 1 always.Each separator 45 is mounted to and can moves transverse to the web flow direction, so that can be adjusted into different coating width.Laterally moving of each separator 45 preferably carried out automatically by a servo motor, makes each separator 45 at least can mobile 500mm, so that also can be adjusted into the very big coating width of difference.
Each separator 45 has a top collection surface 46, and its best outward-dipping extension outwards flows away the dispersion thing of arrival.The direction that collection surface 46 is inside, that is towards the curtain center direction, be bent upwards with a sharp separation seamed edge 48 and finish, its blade-like ground cuts off curtain 39 in the position that requires.
