Description
Technical field
The present invention relates to be used to handle the method and apparatus of fiber web, this equipment comprises glue (sizing) mixture, coating material or similar treatment mixture is assigned to device on the specific board web.The present invention also can be used for paper web and other corresponding fiber webs.
The application relates to by press polish and carries out applying glue (surface gummed), painted (pigmenting), coating and handle width of cloth material.Hereinafter, will describe the present invention as an example with applying glue, applying glue is the most preferred embodiment of the present invention.Yet the present invention also can be applicable in other the above-mentioned application.
Background technology
Usually, applying glue is meant the surface that the aqueous mixture of starch is coated on cardboard or paper, is pressed into then in the width of cloth material in the nip between a plurality of rollers for example.Applying glue also is used to increase the intensity of width of cloth material.Applying glue can also improve the surface characteristic and the impressionability of paper.Except starch, the applying glue mixture can comprise many additives, and in some cases, latex also can be used as the bond of glue.The present invention can be applicable to all glue mixture and different fiber webs substantially.For some board grades, for example be used for the base stock of corrugated board and corrugated paper, intensity is one of most important characteristic.Because applying glue can be used for significantly improving bending strength and surface strength in other characteristics of cardboard, therefore wishes the applying glue in large quantities of these board grades.At present, can obtain maximum coated weight, but for the demand in modern times, the highest possibility speed of service of pit coating equipment is low excessively by the pit coating equipment.Therefore, modern board machine uses film transfer application to distribute sizing material.In film transfer application, at first sizing material is coated on the surface of film transfer roller, sizing material is passed to width of cloth material from the surface of film transfer roller.Board machine uses synchronous dual coating usually, so width of cloth material passes the nip that is formed by two film transfer rollers.Described two rollers are provided with special-purpose application bar.These equipment can obtain relatively large coated weight on a surface of width of cloth material, that is, wet film 30 is to 35g/m
2Use the difference of coating mixture and surface coated to be that it preferably makes the solid particle of coating mixture remain on the surface of width of cloth material.
Yet the limitation of film transfer coating apparatus is validity reduction and not too economic.Can realize glue is penetrated in the fibre structure of width of cloth material preferably in the nip of film transfer roller, but the length of nip is shorter relatively, therefore the actual absorption that enters in the width of cloth material occurs over just after the nip.In fact, because the drying of glue must get started nip after, so that width of cloth material drying and tangible and in order to guide width of cloth material, so total soak time is shorter.Although can use film transfer press or coating apparatus to distribute a large amount of processing materials, a large amount of processing materials can form pit between the surface of the surface of width of cloth material and film transfer roller.Higher width of cloth material speed can increase the risk that forms pit, even but also can form pit under lower speed.Because pit causes splashing and the vibration of width of cloth material, therefore the formation of so-called small pit has limited maximum coated weight, and, because the strong turbulence of pit, the formation of pit even limited air and passed through nip.In film transfer nip, when using a large amount of glue, it is very wet that width of cloth material is made, and this can cause the problem of maneuvering performance aspect.Because width of cloth material wets, thereby so width of cloth material become insecure and be torn easily.Wetting and the dry size that also can change width of cloth material, and must be by regulating width of cloth material tension force and may utilizing spreader roll to consider the change of size.The application chamber that designs the film transfer coating apparatus very meticulously is to guarantee the uniform distribution of glue.Yet, want frequent surface to remove material from fiber web, and described material can directly be passed to application chamber on the surface of film transfer roller or with machine cycles together, particularly when material stops under scraper strip, can cause like this disturbing, and even may cause obstruction in the application chamber.In addition, scraper strip and retainer thereof wear and tear comparatively fast, cause maintenance intervals shorter.The output that can cause higher maintenance cost like this and interrupt causing owing to maintenance reduces.Owing to always comprise impurity in the regenerated fiber with abrasive action, therefore in the machinery that uses regenerated fiber, these problems are particularly evident, are the pigment application particle that includes fiber as the impurity with abrasive action that wherein can be mentioned, most important.Because regenerated fiber is unusual important material, therefore especially to emphasize these problems at the machine that is used for the Production and Packaging cardboard in the production of cardboard.In coating procedure, air and impurity enter into machine cycles easily, must by effective deaerator (deaerator) and screening installation it be removed subsequently.Costing an arm and a leg of these equipment, and required machine cycles is longer, and the volume of described machine is also bigger.
Problem that takes place in the film transfer application and limitation are emphasized differently in the production of different product.Obviously, the damage danger with width of cloth material of strong board grades does not have dangerous serious than the damage of the width of cloth material thin paper grade, that may be made by regenerated fiber.On the other hand, in the production of printing paper or print paper sheet, the wearing and tearing of equipment or pollution reduce.
In the coating or applying glue of paper or cardboard, after scraping, can measure the amount that is delivered to the processing material on the width of cloth material by the roller of film transfer coating apparatus by applicator roll being exposed to infra-red radiation, by this method, determine to stay the water yield in the coating material layer in the glue or on the roller based on the decay of radiation.Based on the water yield of determining, the solid content of handling material and the carry-over factor between width of cloth material and the applicator roll, can calculate the amount of the processing material that is delivered on the width of cloth material.By this method, be difficult to determine the formation and the size of small pit.Also can estimate the amount of the coating material of being kept here by width of cloth material based on the amount of scraping the glue that chips away and turn back to the machine groove from roller.Although said method also can be determined pit with certain precision, owing to supply to the amount of the glue in the nip and turn back to the difference of the amount of the glue in the machine groove, even also be difficult to control pit before the nip by this method.
Summary of the invention
The object of the present invention is to provide a kind of equipment, can will handle material distribution to the surface of the fiber web that moves by this equipment, the amount of described processing material can significantly change, and the infiltration of described processing material can be controlled, avoiding traditional film transfer press or the limitation in the pool presses, these limitations for example are the leakage of handling material and the damage of width of cloth material.
The present invention is intended to be assigned at least one surface of width of cloth material handling material blends, subsequently, width of cloth material is guided in the nip between two rollers described nip and the certain distance in distribution locations interval.In this nip, forms small pit by the processing material of introducing, can measure the apparent height of pit and regulate the height of pit, thus realization accurately, the infiltration of desirable processing material, avoid damaging width of cloth material simultaneously.
Described in the characteristic of the feature of Apparatus and method for of the present invention such as independent claims.
Can obtain significant advantage by the present invention.
The most important advantage of the present invention is significantly to change coated weight.Especially, owing to can obtain relatively large coating, equipment according to the present invention has advantage for early stage method.Because the long retention time, even say for a large amount of processing materials, this processing material of chien shih places on the surface of width of cloth material and the inside of width of cloth material when also having, and can not squeezed out in the nip of roller.On the principle, this device can use a large amount of as far as possible glue or coating material as required in the required scope of product known today.If desired, a large amount of coatings also may be produced the product category that makes new advances.Handling the amount of material and the profile of formation can regulate by the quantity delivered of nozzle or by the size that changes nozzle.Retention time only can be regulated by the distance that changes between coating unit and the pressure roller.The last adjusting of glue infiltration is undertaken by the pressure of the nip of change pressure roller.Another factor of influence infiltration is the apparent height of the small pit of formation.According to the present invention, can measure the apparent height of pit and increase coated weight, if desired, also can reduce the distance between nip and the coating position.By this adjusting, can avoid the height of pit to increase too much with respect to width of cloth material speed, can avoid producing the problem of above-mentioned leakage and the damage of width of cloth material simultaneously.
Most preferably, on the two sides of width of cloth material, carry out applying simultaneously, therefore, only need a treating stations and the required drier of this treating stations.Yet the processing material blends of different amounts can be assigned on the not homonymy of width of cloth material, perhaps even can use different processing material blends.This equipment can also directly carry out dual-coating on wet surface.This can finish by form roll nip in film transfer unit commonly used, thereby makes pressure roller have application bar commonly used, thus second layer glue is delivered to the width of cloth material in the nip.The treatment mixture of high temperature can be dispensed on the surface of width of cloth material, so treatment mixture is not too sticking usually, thereby can on the surface of width of cloth material, becomes dry quickly.When width of cloth material is still when hotter, can also accelerate evaporation of water by width of cloth material is directly guided to coating unit from drier.
For example the calender nip also can be used as roll nip, is heatable roller so that one of them roller is soft roller and another roller.Correspondingly, one of them roller or even two rollers can be with bringing replacement, nip can be formed by boots shape calender (shoe calander).Because heatable roller or band, if it is enough to be passed to the drying effect of the width of cloth material that is positioned at the nip place, then can eliminate after the squeezing long, be preferably the exsiccation in adjustable retention time.Therefore, by the present invention can be only to apply and the calendering nip of heat replaces the nip press, press polish and the drying that apply, apply.Can omit very expensive fluid bed (fluid bed) or infrared drier thus, and can reduce the acquisition price of system, and system can be arranged in the less space, when upgrading production line, this has superiority very much.By amyloid glue and different coating mixtures, this equipment can avoid glue to be adhered to hot-rolling or belt surface.When heating when avoiding adhering, the selection of size and material is very crucial.
Except that foregoing, also avoided the defective of the gummed that causes by film transfer press, described defective is: the glue in the width of cloth material does not fill infiltration, i.e. the limitation of product strength; Film transfer nip is passed in a large amount of glue guiding, promptly avoids forming in roll nip small pit; And the particularly application bar in using the machine of regenerated fiber and the quick wearing and tearing of shaft bar.Owing to do not have application chamber, so can avoid from the obstruction in the chamber that the material that width of cloth material gets loose causes.Therefore the material that gets loose from width of cloth material can not enter machine cycles, need not to screen in order to remove impurity glue mixture.Usually, owing to can the glue mixture that all are to be coated guide on the width of cloth material, therefore even do not need to return circulation.Collecting under the situation of unnecessary glue, also can easily unnecessary glue be led back to and supply with in the groove from roller or spray chambers.In the case, because the amount of glue is less, so required screening installation is not expensive.Except that these, the shortcoming of pool presses is the limitation of the speed aspect that causes of the leakage owing to pit, this limitations restrict the possibility that applies with required width of cloth material speed at present of pool presses.
Description of drawings
Below will be by example and the present invention will be described with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of being seen one embodiment of the present of invention from the side;
Fig. 2 is the schematic diagram of being seen another embodiment of the present invention from the side;
Fig. 3 is the detail view of Fig. 2.
The specific embodiment
In Fig. 1, be depicted as according to gummed of the present invention station (gluing station) and be configured in the production line.Along the direction of motion of width of cloth material 1, first parts are cylinder group 2, and width of cloth material 1 directly guides to coating equipment 3 from this cylinder group 2.After this coating equipment 3 is pressure roller 4 and air dryer 5, and described width of cloth material continues to be directed to handle further from these pressure roller 4 and air dryer 5.It between cylinder group 2 and coating equipment 3 measuring instrument 6 that is used to monitor width of cloth material 1.
Coating equipment 3 comprises the pressure roller 8 by the bearings on the framework 7, and described pressure roller form nip, and the width of cloth material of having handled 1 passes described nip.Pressure roller 8 and framework 7 can be the parts of the film transfer coating apparatus used always, and therefore in this scheme, coating equipment is corresponding to the film transfer coating apparatus, and the pressure roller 8 of coating equipment can be removed from this film transfer coating apparatus.Width of cloth material 1 is directed to via width of cloth material guide reel 9 and runs directly downwards to pressure roller 8.Zone between guide reel 9 and the pressure roller 8 is sealed on the both sides of width of cloth material by housing 10.Therefore, width of cloth material 1 moves in the space that is surrounded by guide reel 9, pressure roller 8 and housing 10.Can seal the edge of width of cloth material 1 and other opening by the seal trim strip of rubber or sheet metal.The nozzle 11 of necessary amount is arranged in the housing 10, and the glue that is used for having atomized is assigned to the surface of width of cloth material.Most preferably, pressure atomized fog jet can be used for making atomization gas to cover equably and atomization gas is become dry.Glue can make the pressure on the nozzle suitably less, usually less than 1Mpa, is about 1 usually to 10bar.Yet the water content of handling in the material blends is very high, thereby owing to for example higher humidity of atomizing air, described atomizing air almost can not make the mixture of enclosure interior become dry unfriendly.If desired, water vapour can be used as atomization gas, can not become dry thus, and can heat described processing material blends simultaneously.In this embodiment since in the formed chamber or the processing material blends or the spraying in the housing of the condensation on the housing wall can drip to or fall on the pressure roller 8, and be passed to width of cloth material 1 subsequently, thereby do not need to handle the material recovery system.The wall of housing 10 can be heated, and the spraying that adheres on the wall can not become dry.To cause producing in the width of cloth material 1 under the situation of defective at the processing material that flows to pressure roller 8, also can unnecessary processing material be collected, and described unnecessary processing material can be drawn and get back to machine and circulate or guide in the gatherer (pulper) by a plurality of grooves of for example housing 10 bottoms.
If desired, can use many row's nozzles.Therefore, for example during cleaning, when row's nozzle broke down, this machine still can move by the nozzle that uses other.Most preferably, double spread can be used for, but if desired, one side can certainly be only be coated with according to equipment of the present invention.At width of cloth material in damaged and other the production interrupt procedure, nozzle can for example turn over 180 ° or 90 ° and towards rinse bath, can check, cleans or change nozzle thus from housing.The wall of housing can easily be opened to clean.
In the above-described embodiments, can regulate the retention time by the position that changes the nozzle row in the housing 10.Yet like this, housing can become big and adjustment stroke is shorter usually.
In according to Fig. 2 and scheme shown in Figure 3, whole nozzle body 10 can move with respect to nip.In this embodiment, width of cloth material directly is directed to the nip of pressure roller 8 from guide reel 9, so that the both sides of width of cloth material engage with pressure roller 8 simultaneously.Retention time on width of cloth material 1 two sides is equated and apply and squeezing between the time interval equate.Nozzle body 10 is configured on the guide rail 12, and nozzle body 10 can move with the distance between the nip that changes 8 of coating position and pressure roller along guide rail.The length of this guide rail 12 can be very long.In fact, only can on the length of free space and free travel, control the described width of cloth material of guiding, therefore, limit the length and the longest retention time of guide rail 12.
According to the present invention, regulate the retention time can form aequum on the width of cloth material that will enter nip subsequently processing material.Described adjusting can consider that following factor carries out, and, handles the amount of once changing of material that is, or other factors of production or quality aspect (for example the material of width of cloth material speed, bottom width of cloth material or other).Selectively, can carry out described adjusting continuously based on measuring.Described adjusting can be based on the measurement of the apparent height of small pit, enter the measurement of processing material of width of cloth material nip and the measurement of surface profile or surface quality subsequently, perhaps, for example also can regulate based on the speed of width of cloth material.
The measurement and the adjusting of the apparent height that an essential feature of the present invention is small pit are to obtain suitable infiltration.Obviously, described measurement can not be undertaken by contact element, so described measurement must be finished by the non-contact sensor 20 (Fig. 2) of for example laser, inductive pick-up or infrared sensor.The amount of processing material to be coated can be regulated by measuring tentatively.The amount that applies can be controlled by the quantity delivered of control coating equipment, and the supply of described coating equipment is to be undertaken by the control coating equipment according to the information that is input in control system or the computer.Because the influence of the retention time (promptly handle material lip-deep setting-up time at width of cloth material) of infiltration between also mainly being applied and squeezing, be favourable so the adjusting of retention time is combined with the measurement of the apparent height of small pit.When before the nip channel being arranged, no matter how nip designs, small pit is formed in the nip all the time.Therefore, the measurement of the height of small pit all is suitable for for control roll nip and band nip.The apparent height that increases small pit can increase the amount of permeating and being delivered to the processing material of width of cloth material, and reduces the amount that apparent height can correspondingly reduce to permeate and be delivered to the processing material of width of cloth material.Can come to determine high as far as possible apparent height according to for example handling properties of materials and width of cloth material speed for the nip of each type.On each nip, in pit, begin to form a plurality of vortexs and be accompanied by and splash, this width of cloth material and may damage width of cloth material of will causing making dirty.The measurement of apparent height can be used for guaranteeing that this does not highly transfinite.Limiting altitude can come be determined by experience or by calculating, and limiting value can and utilize the information of collecting at the run duration of equipment determine more accurately by test run.
According to the present invention, the mixture that is assigned on the width of cloth material 1 must wet when entering into nip.Herein " wetting " means: nip pressure can influence the infiltration of glue in width of cloth material especially, that is, glue mixture can be squeezed the fibrage inside of width of cloth material.Otherwise nip is with inoperative.The distribution district of glue mixture and the distance between the nip, and nip pressure can be used for regulating the infiltration in the required width of cloth material 1.Yet even the distance of the distribution district of glue mixture and nip fixed interval, this glue mixture also can be assigned on the width of cloth material, but can not carry out main adjusting usually in the case.During use, this glue mixture normally heat, be approximately 85 °, glue can heat to remain on this temperature by following manner, promptly, can keep this temperature by heat exchanger by before supplying to nozzle at glue, or even by in nozzle self energising keep this temperature or keep this temperature by the heat medium that in jet stem, circulates.Heating glue can reduce its viscosity, strengthens the atomizing in the nozzle, and accelerates the lip-deep evaporation of water of width of cloth material.Because width of cloth material is from the roller in the last dryer roll group, so width of cloth material is quite warm usually, like this, water can evaporate from the hot glue aqueous mixtures that touches hot width of cloth material surface very effectively.
Can replace the film transfer roller with for example calender nip in the method, this nip has the roller that has soft-surface as first roller, and as the heatable hard roller of second roller.Described two rollers can also all be soft or hard, and one or more in the described roller can be heatable.If described roller differs from one another, then may need two roll nip.Because after through first roll nip, the surface of width of cloth material may be very dry, therefore second roll nip is less for the effect of the infiltration of handling material yet in the case.Also can use the belt calender or the boots formula calender that comprise one or two nip in turn to replace above-mentioned roll nip.If in calender, use metal tape, then can easily heat or cooled metal bands to change the surface characteristic of width of cloth material.
The present invention is very suitable for upgrading or replacing existing pool glue press (pool glue press) or film transfer press.In the case, can from this equipment, remove formation pit or corresponding application chamber, coating material or the required technical parts of glue circulation.According to the present invention, can replace these painting methods by configuration spray application bar before roll nip.This update mode is relatively cheap, and by this update mode, and the amount of service speed and used processing material can substantially improve.Because it is bigger to handle the amount of material, so this equipment can be used to produce than previous wider product.
The present invention also can use with common film transfer coating apparatus.
