U3541 iU3541 i
Den foreliggende opfindelse angår et apparat til imprægnering af bølgepap og af den i indledningen til krav 1 angivne art.The present invention relates to an apparatus for impregnating corrugated board and of the kind specified in the preamble of claim 1.
Fra dansk patentansøgning nr. 4703/68 kendes et sådant appa-5 rat, hvor de langs hver af bølgepappets kanter lejrede elementer griber om og til en vis grad tætner de åbne ender af bølgepappets kanaler. Med disse kendte apparater kan man opnå en yderst tilfredsstillende imprægnering ved høj fremføringshastighed af bølgepappet, nemlig 100 m/min. eller mere.From Danish Patent Application No. 4703/68, such a device is known, in which the elements stored at each edge of the corrugated cardboard grip about and to some extent close the open ends of the corrugated cardboard channels. With these known devices, an extremely satisfactory impregnation can be achieved at high feed rate of the corrugated cardboard, namely 100 m / min. or more.
10 Dette forudsætter imidlertid et ret højt og konstant vakuum i bølgepappets kanaler, og da man ikke kan opnå en fuldstændig tætning mellem bølgepappet og de langs dettes kanter anbragte elementer, er man udsat for, at bølgepappet enten til stadighed eller momentvis trækkes fra et retlinet forløb og 15 over mod det element, hvorfra der tilvejebringes vakuum.10 However, this requires a fairly high and constant vacuum in the corrugated cardboard channels, and since a complete seal between the corrugated board and the elements disposed along its edges cannot be obtained, the corrugated board is either continuously or momentarily pulled from a straight line. and 15 toward the element from which vacuum is provided.
Ved den foreliggende opfindelse er det tilsigtet at tilvejebringe et apparat, hvor sikkerheden, for at bølgepappet under sin fremføring ikke trækkes sideværts enten til stadighed eller lejlighedsvis, er forøget.It is an object of the present invention to provide an apparatus in which the safety, so that the corrugated cardboard is not pulled laterally or continuously, during its advance, is increased.
20 Dette opnås ved et apparat, der er ejendommeligt ved det i krav 1's kendetegnende del angivne.This is achieved by an apparatus peculiar to the characterizing part of claim 1.
Med et sådant apparat kan man arbejde med et højere vakuum end med det ovenfor nævnte apparat, og det medfører den yderligere fordel, at imprægneringszonen kan gøres kortere.With such an apparatus it is possible to work with a higher vacuum than with the above-mentioned apparatus, and this has the added advantage that the impregnation zone can be made shorter.
25 For at sikre den ønskede absolut ligeliniede fremføring af bølgepappet er det ifølge opfindelsen hensigtsmæssigt, at hvert bånd på sin inderside har langsgående spor, og at båndenes bærevalser har dermed komplementære spor, således at hvert bånd er styret i en absolut retliniet bevægelse.In order to ensure the desired straight-line feed of the corrugated cardboard, it is appropriate according to the invention that each strip on its inside has longitudinal grooves and that the strip rollers have complementary grooves, so that each strip is guided in an absolutely rectilinear motion.
30 Ved en foretrukken udførelsesform er båndenes bærevalser lejret i en ramme med modstående sidestykker, som hver igen er lejret svingbart om en tap, der er højdeforskydelig i en 2 143541 søjle. Dette muliggør dels en let gennemførlig justering af bølgepapbanens forløb og dels en hurtig adgang til elementerne, såfremt disse skal efterses.In a preferred embodiment, the strap support rollers are mounted in a frame with opposite side pieces, each of which is pivotally mounted about a pin which is height-displaceable in a column. This allows for easy adjustment of the course of the corrugated board path and for quick access to the elements if these are to be inspected.
For yderligere at sikre, at båndene udøver et jævnt tryk 5 på bølgepappet over hele dettes flade, kan ifølge opfindelsen enderne af det ene par af bærevalserne hver være lejret justerbare i såvel lodret som vandret retning, medens enderne af det andet par af disse valser er lejret justerbare i vandret retning.To further ensure that the bands exert an even pressure 5 on the corrugated board over its entire surface, according to the invention, the ends of one pair of the carrier rolls may each be mounted adjustable in both vertical and horizontal directions, while the ends of the other pair of these rollers are the bearing is adjustable in a horizontal direction.

I fig. 1 ses et almindeligt bølgepapfremstillingsapparat, 10 som har et antal enkeltbølgepapmaskiner 2, 4, 6, og en rullestation 8 for tilførsel af materiale til en dobbelt bølgepapmaskine 10 samt en limningsstation 14. I det viste anlæg til fabrikation af det i fig. la viste bølgepap, er enkelt-bølgepapmaskinerne 4 og 6 midlerti-15 digt udkoblede reserver, og enkelt-bølgepapmaskinen 2 udformer fra papirruller et laminat med et fibrøst papirlag 2a og et dertil fastgjort bølgeformet papirlag 2b. Fra rullestationen 8 udformes bundfladelaget 8a. Bølgepappet 16 passerer derefter successivt gennem en opvarmningsafde-20 ling 18, en afkølingsafdeling 20, en intermitterende fungerende afskæresaks 22, et tredobbelt virkende længdefure- og klippeorgan 24, et roterende afskæreorgan 26 og et udtageorgan 28 for det frigjorte bølgepap. Som almindeligt på området er alle førnævnte bølgningskomponenter synkroniserede.In FIG. 1 shows a conventional corrugated cardboard making apparatus 10 having a plurality of single corrugated cardboard machines 2, 4, 6, and a rolling station 8 for supplying material to a double corrugated cardboard machine 10 and a bonding station 14. In the plant shown for manufacturing the embodiment of FIG. 1a, the corrugated cardboard machines 4 and 6 are temporarily disengaged and the single-corrugated cardboard 2 forms from paper rolls a laminate with a fibrous paper layer 2a and a corrugated paper layer 2b attached thereto. From the rolling station 8, the bottom surface layer 8a is formed. The corrugated cardboard 16 then passes successively through a heating compartment 20, a cooling compartment 20, an intermittent working cutter scissors 22, a triple-acting longitudinal and cutter member 24, a rotary cutter member 26 and a release corrugated discharge member 28. As is usual in the art, all of the aforementioned wave components are synchronized.
25 I overensstemmelse med den foreliggende opfindelse er der på den begrænsede plads mellem afskæresaksen 22 og fure- og klippeorganet 24 indrettet en imprægneringsstation 30 til imprægnering af de tværgående riller i det på langs retlinet fremførte, horisontalt beliggende bølgepap med et pas-30 sende imprægneringsmateriale, der kan give vandtæthed, ild-fasthed, struktur-forstærkning, vellugt, isolering eller andre egenskaber, og imprægneringsmaterialet kan f.eks. være bitumen, paraffin, vandglas, syntetisk harpiks, lim, paraffinbitumineret emulsion, kunstharpiks-voksblandinger, 35 væskeformige syntetiske materialer, syntetiske opskummende 4 143541 formstoffer, kunstharpikser, siliconer, natriumsilicatopløs-ninger, alkaliske metalsilicater, vinylharpiks og tilsvarende stoffer. Tilførselsorganet 32 for imprægneringsmiddel er indrettet til tilførsel af imprægneringsmidlet ved den ene af 5 bølgepappets længdekanter, og sugeorganerne, der har en voks-separator 34 og et vakuumpumpe 36, er anbragt ved den anden af bølgepappets længdekanter til tilvejebringelse af et vakuum i pappets tværgående kanaler og trække det imprægnerende materiale fuldstændigt gennem kanalerne.In accordance with the present invention, an impregnation station 30 is provided for impregnating the transverse grooves in the longitudinally extending, horizontally located corrugated board with a suitable impregnating material in the confined space between the cutting shaft 22 and the cutter and cutting means 24. which may provide waterproofness, fireproof, structural reinforcement, odor, insulation or other properties, and the impregnating material may e.g. be it bitumen, paraffin, water glass, synthetic resin, glue, paraffin bituminated emulsion, synthetic resin wax mixtures, 35 liquid synthetic materials, synthetic foaming resins, synthetic resins, silicones, sodium silicate solutions, alkaline metal silicates and vinyl resins. The impregnator supply means 32 is adapted to supply the impregnating agent at one of the longitudinal edges of the corrugated cardboard, and the suction means having a wax separator 34 and a vacuum pump 36 are arranged at the other of the corrugated longitudinal edges of the corrugated cardboard to provide a vacuum can in the cardboard. and completely pulling the impregnating material through the channels.
10 Af fig. 2 og fig. 4 fremgår, at imprægneringsstationen har en bæreramme 40, der ved hver af dets ender har en tap 42, som forløber ud fra en endeplade 43 og ind i en tilsvarende lodret forløbende styreåbning i de stationære anbragte lodrette søjler 44. Bærerammen er ved sin nederste ende understøttet 15 ved hjælp af samvirkende fodruller 46 og stationære kurve-skinneformede understøtningsorganer 48. Bærerammen er forskydelig fra den viste operative stilling til en inoperativ vedligeholdelses- eller opbevaringsstilling, som vist med stiplede linier i fig. 4. Endepladerne 43 er stift forbundet 20 ved hjælp af tværgående forbindelsesstænger 50 i rammen.10 From FIG. 2 and FIG. 4 shows that the impregnation station has a support frame 40 having at each of its ends a pin 42 extending from an end plate 43 and into a corresponding vertically extending guide opening in the stationary vertical columns 44. The support frame is at its lower end supported 15 by cooperating foot rolls 46 and stationary curve rail-shaped support members 48. The support frame is slidable from the operative position shown to an inoperative maintenance or storage position, as shown in broken lines in FIG. 4. The end plates 43 are rigidly connected 20 by transverse connecting rods 50 in the frame.
Et par overruller 52, 54, som er drejeligt lejret ved begge ender i lejer, der bæres af bærerammens endeplader 43, understøtter et langsgående øverste endeløst bånd 56, som har sit nedre løb nær oversiden af bølgepappet 16. Tilsvarende 25 er der ved hver af bærerammens ender drejeligt lejret underruller 60, 62 og 64, der bærer et langsgående nederste endeløst bånd 66, der med dets øverste vandrette løb befinder sig nær undersiden af bølgepappet 16. Det øverste- og det nederste bånd har en sådan bredde i forhold til bredden af 30 bølgepappet, at disse, når vakuumet er frembragt i bølgepappets kanaler, hvilket vil blive forklaret nærmere i det følgende, ved sugning trækkes mod hinanden til fastspænding mellem sig af bølgepappet 16, hvorved sideforskydning af bølgepappet i forhold til bærerammen effektivt hindres. Som det 35 fremgår af fig. 2 og 3 er bredderne for de endeløse bånd 5 143541 56, 66 i forhold til rullerne 52, 54, 60, 62 og 64 er båndene 56, 66 på deres indvendige flader forsynet med langsgående ribber eller spor henholdsvis 56a og 66a, der kan optages i til ribberne afpassede furer eller komplementære spor i rul-5 lerne, som vist i fig. 5. Selv om der i den viste udførelsesform er omtalt anvendelse af ribber som i polykileremme, vil det være klart for en fagmand på området, at der kan anvendes andre fastholdeorganer i stedet for, f.eks. kan der lige så godt anvendes styreruller.A pair of rollers 52, 54 pivotally mounted at both ends in bearings supported by the endplate 43 of the support frame support a longitudinal upper endless belt 56 having its lower run near the top of the corrugated cardboard 16. Correspondingly 25 there are at each of the the ends of the support frame are pivotally mounted lower rollers 60, 62 and 64 which carry a longitudinal bottom endless band 66 which, with its upper horizontal run, is located near the underside of the corrugated cardboard 16. The upper and lower band have such width relative to the width of the 30, as the vacuum is produced in the channels of the corrugated board, which will be explained in greater detail hereinafter, by suction is pulled towards each other for clamping between them by corrugated board 16, thereby effectively preventing lateral displacement of the corrugated board relative to the carrier frame. As shown in FIG. 2 and 3, the widths of the endless bands 5, 35, 56, 66 relative to rollers 52, 54, 60, 62 and 64 are provided on their inner surfaces with longitudinal ribs or grooves 56a and 66a which can be accommodated, respectively. in grooves or complementary grooves in the rollers, as shown in FIG. 5. Although in the illustrated embodiment, the use of ribs as in polyethylene belts is disclosed, it will be clear to one skilled in the art that other retaining means may be used instead of, e.g. steering rollers can be used equally well.
10 Som vist i fig. 4 er det nederste endeløse bånd 66 drevet ved hjælp af apparatets hoveddrivorgan 30 over et reduktionsgear 70 og et kæde- og kædehjulstræk 72, hvor den lineære hastighed for det vandrette øvre løb af båndet 66 er lige så høj eller lidt højere end den lineære hastighed for bølgepap-15 pet. Rullerne 52, 54, 60, 62 og 64 er hensigtsmæssigt forsynet med nøjagtigt virkende justeringsmidler, der kan bringe rullernes akser til at ligge nøjagtigt horisontalt og vinkelret på bølgepappets længdeakse, hvorved skævt fremadløb af bølgepappet ved dets passage gennem imprægneringsstationen 20 undgås. Som vist i fig. 6, kan en langsgående justering af et bærende fodstykke 76, der er anbragt i et rammeglide-stykke 78, foretages ved hjælp af en indstillingsskrue 80, medens en langsgående justering af overrullernes fodstykke 82, der er anbragt på et rammeglidestykke 84, kan foretages 25 ved hjælp af en indstillingsskrue 86. En vertikal justering af hver ende på overrullerne kan foretages ved hjælp af en indstillingsskrue 88.10 As shown in FIG. 4, the lower endless belt 66 is driven by the main drive means 30 of the apparatus over a reduction gear 70 and a chain and sprocket 72 where the linear velocity of the horizontal upper run of the belt 66 is as high or slightly higher than the linear velocity of corrugated cardboard-15 pet. Conveniently, rollers 52, 54, 60, 62 and 64 are provided with precisely adjusting means which may cause the axes of the rollers to lie exactly horizontally and perpendicularly to the longitudinal axis of the corrugated board, thereby avoiding skewed forward passage of the corrugated board as it passes through the impregnation station 20. As shown in FIG. 6, a longitudinal adjustment of a supporting footpiece 76 arranged in a frame slide piece 78 can be made by means of an adjusting screw 80, while a longitudinal adjustment of the footpiece 82 of the rollers arranged on a frame slide piece 84 can be made. by means of an adjusting screw 86. A vertical adjustment of each end of the rollers can be made by means of an adjusting screw 88.
Forskydeligt forbundet med bærerammens endeplader 43 til sideværts justering i forhold til bølgepappet findes som vist 30 i fig. 2, 3 og 7 et par glideorganer 90, til hvilke der ved hjælp af hængseltappe 92 er hængselforbundet henholdsvis et tilførselsorgan 94 for tilførsel af imprægneringsmidlet og et sugekanalorgan 96, der forløber langs med og nær ved modstående kanter af bølgepappet. Kanalorganerne er forsy-35 net med til siden udragende organer 94a, 96a, der er ført gennem dertil svarende styreåbninger, som er udformet i hen- 6 143541 holdsvis den forreste og den bageste kant af endepladerne 43, idet nævnte udragende organer samarbejder med nævnte åbninger til at understøtte kanalorganerne i en begrænset svingbevægelse i et horinsontalt plan omkring deres respektive 5 hængseltappe 92. For at justere kanalorganerne i forhold til bærerammen 40 til afpasning efter bølgepap af varierende bredder, og for at styre kanalorganernes drejningsretning omkring deres hængseltappe 92 er der til rammens tværstivere 50a, der strækker sig mellem løbene på det nederste endeløse 10 bånd 66, fastgjort fire hydrauliske cylindre 97, 98, 100 og 102. Ved samtidigt at drive stemplerne frem eller tilbage i cylindrene vil den indbyrdes afstand mellem kanalorganerne blive henholdsvis forøget eller formindsket.Slidably connected to the support frame end plates 43 for lateral adjustment relative to the corrugated board is as shown 30 in FIG. 2, 3 and 7 are a pair of sliding members 90 to which, by means of hinge pins 92, are hingedly connected respectively a supply means 94 for supplying the impregnating means and a suction channel means 96 extending along and near opposite edges of the corrugated board. The channel means are provided with laterally projecting means 94a, 96a which are passed through corresponding guide openings formed in the front and rear edges of the end plates 43, respectively, said protruding members cooperating with said openings. to support the channel means in a limited pivotal movement at a horizontal plane about their respective hinge pins 92. To adjust the channel means relative to the carrier frame 40 for adjusting to corrugated board of varying widths, and to control the direction of rotation of the channel means about their hinge pins 92, transverse struts 50a extending between the bores of the lower endless belt 66 attached to four hydraulic cylinders 97, 98, 100 and 102. By simultaneously pushing the pistons forward or backward in the cylinders, the mutual distance between the channel members is increased or decreased, respectively.
Som vist i figurerne 7-11 har hver af kanalorganerne for 15 henholdsvis tilførsel af imprægneringsmiddel og for sugning i deres længderetning et antal sektioner, der ved deres tilstødende ender som vist i fig. 11 er sammenføjet ved hjælp af samvirkende fremspring og udsparinger 106, og ved hjælp af stangformede organer 108, der strækker sig på 20 langs gennem sektionerne til sammenkobling af disse til dannelse af en stiv samling. Kanalen 94 for tilførsel af imprægneringsmaterialet omfatter som vist i fig. 8 en første række i kanalens længderetning med indbyrdes afstande anbragte udløb 110, til hvilke udløb et imprægneringsmateriale af 25 ønsket konsistens bliver ført fra en kilde 32 gennem opvarmede rørledninger henholdsvis 112, 114 og 116, der indeholder strømningsreguleringsmidler henholdsvis 120, 122 og 124, hvorved imprægneringsmaterialet bliver tilført ved bølgepappets ene længdekant. Endvidere omfatter imprægneringsma-30 terialet som vist i fig. 9 en anden række i kanalens længderetning med indbyrdes afstande anbragte udløb 130, til hvilke der tilføres varm luft fra en kilde 132 gennem rørledninger 134, 136, 138, 140 og 142, der indeholder strømreguleringsmidler henholdsvis 144, 146, 148, 150 og 152. Endelig 35 er der også ført varm luft til udløbene 110 i kanalsektio-nerne for tilførsel af imprægneringsmateriale gennem rørled- 7 143541 ninger 156, 158 og 160, der Indeholder strømreguleringsmidler henholdsvis 162, 164 og 168. På tilsvarende måde indeholder sugekanalorganet 96, som afgrænser et sugekammer 96c med en lodret bagvæg 96d, en række i kanalens længderetning med ind-5 byrdes afstande anbragte udløbet 170, der som vist i fig. 10 er i forbindelse med vakuumpumpen 36 gennem rørledninger 174, 176, 178, 180, 182 og 184, der indeholder strømregulerende midler henholdsvis 186, 188, 190, 192, 194 og 196. Kanaler 198 og 200 strækker sig på langs gennem henholdsvis tilfør-10 selskanalen og sugekanalen for tilførsel af et varmt fluidum, f.eks. damp, gennem sektionerne til bibeholdelse af imprægneringsmaterialet i en varm tilstand. Alternativt kan kanalerne blive opvarmet ved hjælp af elektricitet.As shown in FIGS. 7-11, each of the channel means for supplying impregnating agent and for suction in their longitudinal direction, respectively, has a plurality of sections at their adjacent ends as shown in FIG. 11 is joined by cooperating projections and recesses 106, and by rod-shaped means 108 extending 20 along the sections to interconnect them to form a rigid joint. The channel 94 for supplying the impregnating material comprises, as shown in FIG. 8 shows a first row longitudinally spaced outlet 110 of the duct, to which outlet an impregnating material of desired consistency is passed from a source 32 through heated pipelines 112, 114 and 116, respectively, containing flow regulators 120, 122 and 124 respectively. the impregnating material is supplied at one longitudinal edge of the corrugated board. Further, the impregnating material as shown in FIG. 9, a second row in the longitudinal direction of the duct spaced apart, to which hot air is supplied from a source 132 through pipelines 134, 136, 138, 140 and 142 containing flow control means 144, 146, 148, 150 and 152, respectively. Finally, hot air has also been fed to the outlets 110 in the duct sections for supplying impregnating material through conduits 156, 158 and 160 containing flow control means 162, 164 and 168 respectively. Similarly, the suction duct means 96 which defines a suction chamber 96c with a vertical rear wall 96d, a row in the longitudinal direction of the duct with spaced distances, the outlet 170, which as shown in FIG. 10 is in connection with the vacuum pump 36 through pipelines 174, 176, 178, 180, 182 and 184 containing current regulating means 186, 188, 190, 192, 194 and 196 respectively. Channels 198 and 200 extend longitudinally through supply lines, respectively. The suction duct and suction duct for supplying a hot fluid, e.g. vapor, through the sections for retaining the impregnating material in a hot state. Alternatively, the ducts can be heated by electricity.
Som vist i fig. 8 har imprægneringsmaterialets tilførselska-15 nal 94a et indløb 116a, der er i forbindelse med rørledningen 116 for tilførsel af et imprægneringsmiddel, f.eks. varm voks, i flydende eller forstøvet tilstand, til udløbet 110 gennem et roterbart strømningskontrolorgan 210, der indeholder en på tværs udformet målekanal 212. Som vist i fig. 11 20 og fig. 12 har kontrolorganet 210 et betjeningshåndtag 214, der rager radialt ud gennem en dækplade 216, til manuel indstilling af kontrolorganet 210's målestilling og en kontrol-lering af kvantiteten af imprægneringsmaterialet, som føres til bølgepappets kanaler. Imprægneringsmaterialet føres som 25 vist i fig. 8 nedad i nærheden af en løbe 218, hvorved imprægneringsmaterialet bliver blandet med luft, der bliver tilført gennem en konvergerende kanal 220, til dannelse af en dispersion af imprægneringsmiddel og luft. Denne varme luft er medrevet ved sugning fra en luftbeholdersektion 94b i 30 kanalorganet, som er vist i fig. 8. På en tilsvarende måde bliver luften medrevet ved sugning fra en luftbeholdersektion 94c i kanalorganet 94d for imprægneringsmaterialet, således som vist i fig. 9. For at tætne bølgepapkanalernes ender, der forløber inde i hver af kanalorganerne, er der til-35 vejebragt en langsgående tætningsstrimmel 224, der trykkes nedad til anlæg mod bølgepappets overside ved hjælp af et 143561 8 fjederorgan 226, idet kanten af bølgepappet bliver understøttet ved hjælp af et underlag 228 af et syntetisk formstof-materiale. Hvis det ønskes, kan tætningsstrimmelen indeholde midler, såsom kautsjuklæber eller børster ved enderne af ka-5 nalorganerne til yderligere tætning af bølgepapkanalernes ender over for atmosfæren. Som det fremgår ved sammenligning af fig. 9 og fig. 10 er sugekanalsektionerne identiske med luftkanalsektionerne 94c og 94d i tilførselskanalorganet 94 for imprægneringsmaterialet. I det tilfælde, hvor tætnings-10 strimmelen 224 består af en plade af tyndt materiale, såsom folie, vil dette automatisk blive suget i indgreb med overfladen af bølgepappet, hvorved behovet for et fjederorgan svarende til fjederorganet 226 undgås. For at hindre en større koncentration af imprægneringsmidlet i nærheden af bølge-15 papkanalernes tilførselsender, end ved sugeender, hvilket normalt ville kunne forekomme på grund af hastighedsforøgelsen for imprægneringsmaterialet, når dette bevæges imod sugeorganerne, må forskellige strømningskontrolorganer for henholdsvis imprægneringsmaterialet, den varme luft og sugeled-20 ningerne justeres om nødvendigt. Derfor bliver, ved bølgepappets tilførselsside for imprægneringsmateriale først den varme luft indført i bølgepapkanalerne gennem et rør 134 og et ventilorgan 144, hvorefter imprægneringsmaterialet successivt bliver ført ind i bølgepapkanalerne gennem opvarmede 25 rør 156, 158 og 160, der reguleres af strømningsreguleringsorganer 162, 164 og 168. Ved en passende regulering af disse kontrolmidler indføres de korrekte successive mængder imprægneringsmateriale i bølgepappets kanaler, og en følgende tilførsel af varm luft gennem rørene 136, 138, 140 og 142, der 30 er kontrolleret ved hjælp af ventiler henholdsvis 146, 148, 150 og 152, samvirker med vakuummidlerne til at trække imprægneringsmaterialet gennem kanalerne. Når f.eks. materialets hastighed stiger, kan lufttilførslen formindskes ved en passende kontrollering af ventilorganerne til formindskelse 35 af imprægneringsmaterialet, medens det strømmer gennem bølgepappet. Ligeledes kan det ved vakuumsiden være ønskeligt at have den første gruppe af strømningsreguleringsorganer 9 143541 186, 188 og 190 i en fuldt åben stilling for at give største sugevirkning, medens de efterfølgende strømningsreguleringsorganer 192, 194 og 196 kan være i en delvis neddroslet stilling til at give en reduceret sugeeffekt. Naturligvis 5 kan justeringen af strømningsreguleringsorganerne for rørene til den varme luft, til sugningen og til imprægneringsmaterialet variere i overensstemmelse med det særligt anvendte imprægneringsmateriale, med den lineære hastighed af bølgepappet, i afhængighed af om bølgepappet er af enkelt- eller 10 dobbelt-typen, med bredden af pappet, dimensionerne af dettes kanaler og med andre konstruktive parametre. Alsidigheden ved imprægneringen, der opnås ved hjælp af apparatet ifølge opfindelsen, muligheden for imprægnering af bølgepap med høj produktionshastighed ved en normal produktionsproces, 15 og muligheden for tilpasning af imprægneringsudrustningen til installering på eksisterende bølgepapfremstillingsanlæg er væsentlige fordele, som kan opnås ved det forbedrede apparat. Endvidere giver apparatet en sådan nøjagtig kontrol, at der ikke føres mere voks til bølgepappet, end hvad der er nød-20 vendigt til at opnå den ønskede grad af imprægnering. I modsætning til hvad der er tilfældet ved de hidtil kendte imprægneringsprocesser, kan der opnås en vilkårlig valgt mætningsgrad for bølgepappet.As shown in FIG. 8, the supply channel 94a of the impregnating material has an inlet 116a which is connected to the conduit 116 for supplying an impregnating agent, e.g. hot wax, in liquid or atomized state, to the outlet 110 through a rotatable flow control means 210 containing a transverse measuring channel 212. As shown in FIG. 11 20 and FIG. 12, the control means 210 has an operating handle 214 extending radially through a cover plate 216 for manually adjusting the measuring position of the control means 210 and a control of the quantity of the impregnating material conveyed to the corrugated cardboard channels. The impregnating material is passed as shown in FIG. 8, downstream of a barrel 218 whereby the impregnating material is mixed with air supplied through a converging duct 220 to form a dispersion of impregnating agent and air. This hot air is entrained by suction from an air container section 94b in the duct means shown in FIG. 8. Similarly, the air is entrained by suction from an air container section 94c in the impeller material duct 94d, as shown in FIG. 9. In order to seal the ends of the corrugated canals extending within each of the conduit means, a longitudinal sealing strip 224 is provided which is pressed downwardly against abutment of the corrugated board by a spring member 226, the edge of the corrugated board being supported. by means of a substrate 228 of a synthetic plastic material. If desired, the sealing strip may contain means such as rubber seals or brushes at the ends of the channel means for further sealing the ends of the corrugated canals towards the atmosphere. As can be seen from comparing FIG. 9 and FIG. 10, the suction duct sections are identical to the air duct sections 94c and 94d of the impeller material supply duct 94. In the case where the sealing strip 224 consists of a sheet of thin material such as foil, this will be automatically sucked into engagement with the surface of the corrugated board, thereby avoiding the need for a spring member corresponding to the spring member 226. In order to prevent a greater concentration of the impregnating agent in the vicinity of the supply ends of the corrugated duct, than at suction ends, which could normally occur due to the speed increase of the impregnating material, when it is moved against the suction means, different flow control means for the impregnating material and the suction lines are adjusted if necessary. Therefore, at the impregnating material supply side of the corrugated board, the hot air is first introduced into the corrugated ducts through a pipe 134 and a valve member 144, after which the impregnating material is successively introduced into the corrugated cardboard channels through heated pipes 156, 158 and 160 which are controlled by flow regulators 16 and 16 168. By appropriate control of these control means, the correct successive amounts of impregnating material are introduced into the corrugated cardboard ducts, and a subsequent supply of hot air through the pipes 136, 138, 140 and 142 controlled by valves 146, 148, 150, respectively. and 152, cooperate with the vacuum means to draw the impregnating material through the channels. For example, when As the velocity of the material increases, the air supply can be reduced by an appropriate check of the valve means to reduce the impregnating material as it flows through the corrugated board. Also, on the vacuum side, it may be desirable to have the first group of flow control means 9, 143541 186, 188 and 190 in a fully open position to provide maximum suction effect, while the subsequent flow control means 192, 194 and 196 may be in a partially depressed position to provide a reduced suction effect. Of course, the adjustment of the flow control means for the pipes for the hot air, for the suction and for the impregnating material may vary according to the specially used impregnating material, with the linear velocity of the corrugated board, depending on whether the corrugated board is of single or double type, with the width of the cardboard, the dimensions of its channels and with other constructive parameters. The versatility of the impregnation achieved by the apparatus of the invention, the possibility of impregnating high corrugated cardboard in a normal production process, and the possibility of adapting the impregnation equipment to install on existing corrugated cardboard plants are significant advantages which can be obtained by the apparatus. Furthermore, the apparatus provides such precise control that no more wax is applied to the corrugated board than is necessary to achieve the desired degree of impregnation. Contrary to the prior art impregnation processes, any selected degree of saturation for the corrugated board can be obtained.
Som vist i fig. 7, er kanalorganerne forbundet til svingbe-25 vægelse omkring akser 92, hvorved en yderligere kontrol tilvejebringes til hindring af afvigelser i bølgepappets stilling. Hvis det ønskes, kan ikke viste konventionelle kantdetekteringsorganer indrettes til betjening af de hydrauliske cylindre 96, 98, 100 og 102 til en nøjagtig kon-30 trol af kanalorganernes stillinger og retninger i forhold til bølgepappet. I fig. 13 er der vist en ændret udførelsesform for voksseparatorapparatet, hvori kanalorganerne er anbragt til forskydning uafhængig af bærerammen 232, idet tilførselskanalen for imprægneringsmaterialet er kombineret 35 med en varmeveksler til dannelse af en enhed 220, og sugeka-nalorganet er kombineret med vokssepareringsenheden 222.As shown in FIG. 7, the channel means are connected for pivotal movement about axes 92, thereby providing additional control to prevent deviations in the corrugated board position. If desired, conventional edge detection means shown may not be adapted to operate the hydraulic cylinders 96, 98, 100 and 102 to accurately control the positions and directions of the channel means relative to the corrugated board. In FIG. 13, a modified embodiment of the wax separator apparatus is shown in which the channel means are arranged for displacement independently of the support frame 232, the supply channel for the impregnating material being combined with a heat exchanger to form a unit 220 and the suction channel means being combined with the wax separating unit 222.

Disse enheder kan være anbragt på ruller til sideværts forskydning af bølgepappet ved hjælp af trykmediumcylindrene henholdsvis 224 og 226. Det øverste og det nederste endeløse bånd henholdsvis 228 og 230 bæres af bærerammen 232 til hin-5 dring af bølgepappets sideforskydning under transport gennem imprlgneringsstationen. Ved at kombinere sugekanalen med separeringsenheden opnås en forbedret sugning, og voksets temperatur i separatoren kan lettere kontrolleres til adskillelse fra luften indføring i vakuumpumpeenheden. Tilsvarende 10 kan der ved en kombinering af tilførselsmidlet til tilførsel af imprægneringsmidlet med varmeveksleren opnås en mere ensartet temperatur i vokset.These units may be arranged on lateral displacement rollers of the corrugated board by means of the pressure medium cylinders 224 and 226, respectively. The upper and lower endless belts 228 and 230, respectively, are supported by the carrier frame 232 to prevent the corrugated cardboard lateral displacement during transport through the impregnation station. By combining the suction duct with the separating unit, an improved suction is obtained and the temperature of the wax in the separator can be more easily controlled for separation from the air introduction into the vacuum pump unit. Similarly, by combining the feed agent to supply the impregnant with the heat exchanger, a more uniform temperature in the wax can be obtained.
I fig. 14 er der skematisk vist en anden udførelsesform for imprægneringsmiddeltilførselsorganet til ved enderne af 15 bølgepappets kanaler at tilføre imprægneringsmidlet i form af et tæppe af en voks-luft-dispersion fra et indløb 240 gennem et udløb 242 via et strømreguleringsorgan 244. Når bølgepappet 16 befinder sig ved et tværgående udløb 246, bevirker vakuumet, der er tilvejebragt i kanalerne ved hjælp af 20 sugemidlerne, at voks-luft-tæppet suges ind i kanalerne sammen med den varme luft, der bliver tilført gennem en passage 248. Denne udførelsesform frembyder den fordel, at voks-luft--tæppet kontinuerligt kan blive recirkuleret og kun vil blive suget gennem passagen 246, når bølgepappet er til stede, hvor-25 ved der fås en automatisk afskæring.In FIG. 14, another embodiment of the impregnating supply means is shown schematically at the ends of the corrugated cardboard channels to supply the impregnating agent in the form of a blanket of a wax-air dispersion from an inlet 240 through an outlet 242 via a flow control means 244. When the corrugated board 16 is present at a transverse outlet 246, the vacuum provided in the ducts by means of the suction means causes the wax-air blanket to be sucked into the ducts together with the hot air supplied through a passage 248. This embodiment offers the advantage of that the wax-air blanket can be continuously recirculated and will only be sucked through passage 246 when the corrugated cardboard is present, thereby providing an automatic cut-off.
I fig. 15 er der vist en anden udførelsesform for tilførselsorganet til tilførsel af imprægneringsmiddel, hvilken udførelsesform er hensigtsmæssig til brug i den i fig. 13 viste kombinerede varmeudveksler og tilførselsorgan. I denne udfø-30 relsesform ledes det varme voks til et turbulens blandingskammer 260 gennem varmeveksleren 262 i enheden 220 via en uden luft virkende voksforstøver, der omfatter et dispersionskammer 264 og en forstøverdyse 266. Varm luft føres til turbulens blandingskammeret i konvergerende stråler via rørlednin-35 ger 268 og 270, der indeholder styreventiler henholdsvis 272 11 143541 og 274. Vokset og varm luft blandes grundigt på grund af turbulensen i kammeret 260 og trækkes ved sugning fra kammeret gennem en udløbspassage 276 ved hjælp af det frembragte vakuum i kanalerne i bølgepappet 278 og får derved en konti-5 nuerlig strømning.In FIG. 15, another embodiment of the impregnator supply feeder is shown, which embodiment is suitable for use in the embodiment of FIG. 13 combined heat exchanger and supply means. In this embodiment, the hot wax is passed to a turbulence mixing chamber 260 through the heat exchanger 262 in the unit 220 via an air-operated wax atomizer comprising a dispersion chamber 264 and a nebulizer nozzle 266. Hot air is fed to the turbulence mixing chamber in converging jets via piping. Filters 268 and 270 containing control valves 272 11 143541 and 274, respectively. Waxed and hot air are thoroughly mixed due to the turbulence of chamber 260 and drawn by suction from the chamber through an outlet passage 276 by means of the vacuum created in the channels of corrugated cardboard 278. thereby obtaining a continuous flow.
Por at regulere blandingen af luften med vokset er dysen 266 aksialt forskydelig ved hjælp af ikke viste almindeligt kendte indstillingsorganer mellem den i fig. 15 viste fuldt optrukne stilling og en til højre for denne beliggende stilling 10 nær ved indløbsmundingen til passagen 276. En dræningspassage 280 er tilvejebragt i forbindelse med bunden af blandingskammeret 260 til dræning af vokskondensatet derfra. Som det fremgår af den anden udførelsesform, der er vist skematisk i tværsnit i fig. 16, kan turbulensblandingskammeret 286, som 15 rummer en voksforstøvningsdyse 288, være forsynet med koncentriske varmekapper til afgrænsning af kamre 290 og 292, som tilføres et varmt strømningsmedium, såsom damp eller luft, til at vedligeholde voks-luft-blandingen på en ønsket temperatur. I tilfælde af at strømningsmediet er varm luft, kan 20 denne blive indført i kammeret gennem indløbsåbninger, der er således anbragt, at der kan opnås en forøgelse af turbulensblandingseffekten.To control the admixture of the air with the wax, the nozzle 266 is axially displaceable by means of not generally known adjusting means, shown in the FIG. 15 is shown in a fully drawn position and to the right of this position 10 located near the inlet mouth of passage 276. A drainage passage 280 is provided in connection with the bottom of the mixing chamber 260 for draining the wax condensate therefrom. As can be seen from the second embodiment shown schematically in cross section in FIG. 16, the turbulence mixing chamber 286, which accommodates a wax spray nozzle 288, may be provided with concentric heat caps for defining chambers 290 and 292 supplied to a hot flow medium, such as steam or air, to maintain the wax-air mixture at a desired temperature. In case the flow medium is hot air, it can be introduced into the chamber through inlet openings so arranged as to increase the turbulence mixing effect.
I visse tilfælde kan det øverste endeløse bånd 56 udelades. I f.eks. det tilfælde , hvor et bølgepap skal belægges 25 med et materiale, såsom hvid anilintrykfarve, kan selve belægningslaget tjene som en uigennemtrængelig overdækning, der suges mod det underste bånd 66 ved hjælp af det vakuum der er frembragt i bølgepappets kanaler.In some cases, the upper endless band 56 may be omitted. In e.g. in the case where a corrugated cardboard is to be coated with a material such as white aniline ink, the coating layer itself can serve as an impervious cover which is sucked onto the lower ribbon 66 by the vacuum produced in the corrugated cardboard channels.
For at kunne bibeholde bølgepappets overfladeegenskaber med 30 hensyn til klæbelighed og trykbarhed kan det være ønskeligt ved påsprøjtning, befugtning eller lignende at påføre mindst en af bølgepappets ubeskyttede sider før imprægneringen med en midlertidig belægning af et væskeformigt materiale, såsom vand.In order to maintain the corrugated cardboard surface properties in terms of tackiness and printability, it may be desirable to apply at least one of the corrugated board's unprotected sides prior to impregnation with a temporary coating of a liquid material, such as water, by spraying, wetting or the like.
