Description
457 542 lig yta, varjämte den andra sidan av bandet innehåller mellanrum, som är anordnade sa att vätska kan föras in i desamma från de däremot anliggande filtarna medan väven, filterna och bandet passerar genom griporganet. 457 542 surface, and the other side of the band contains gaps, which are arranged so that liquid can be introduced into them from the adjacent ones the blankets while the fabric, filters and band pass through the gripper.
En viktig fördel med detta band är att det kan utföras i vilken som helst längd, eftersom det icke kräver en dorn under tillverkningen av detsamma. Underlagstyget kan utföras ändlöst med användning av känd teknik och sedan beläggas med materialet.An important advantage of this tape is that it can be performed in which any length, as it does not require a mandrel during the manufacture of the same. The backing fabric can be made endlessly using known technology and then coated with the material.
Det resulterande bandet är bade lätt och tillräckligt stabilt för att kunna användas i en pappersmaskin. Det har tillräcklig nötningshàllfasthet för ett kunna motstå den nötning som kan ske i griporganet. Till skillnad fran material, som är uppbyggda pä liknande sätt som ett gummidäck och kan flyta och/eller sönderdelas, åstadkommas genom uppfinningen ett band, som bibehåller sin sammanhållning. Dette band löser även problemet med utbukt- ning näre griporganet.The resulting band is both light and stable enough to be used in a paper machine. It has sufficient abrasion resistance to be able to withstand the abrasion that can occur in the gripping member. Unlike materials, which are constructed in a manner similar to a rubber tire and can float and / or disintegrate, the invention provides a belt which maintains its cohesion. This band also solves the problem of bulging ning close to the gripping means.
Uppfinningen skall i det följande närmare beskrivas med hänvis- ning till bifogade ritningar.The invention will be described in more detail below with reference to to the accompanying drawings.
Figur 1 visar i sidvy ett langsträckt griporgan enligt uppfinningen.Figure 1 shows in side view an elongate gripping member according to the invention.
Figur 2 visar delvis i sektion och sett framifrån griporganet enligt figur 1.Figure 2 shows partly in section and seen from the front the gripping member according to figure 1.
Figur 3 visar i längdsektion bandet som användes vid uppfinningen.Figure 3 shows in longitudinal section the strap used in the invention.
Figur 4 visar i längdsektion en alternativ utföringsform av bandet som användes enligt uppfinningen.Figure 4 shows in longitudinal section an alternative embodiment of the belt used according to the invention.
Det làngsträckte press- och griporganet enligt uppfinningen för att avvattna en framförd vävnad innefattar griporganet 10, som bildas av en cylindrisk pressvals 12, en trycksko 14 som har en konkav yta vettande mot pressvalsen, och ett band 16 anordnat se att det ligger en mot pressvelsens yta. Den konkeva yten pa tryckskon har omkring samma krökningsredie som pressvalsen. Avståndet mellan pressvalsen och tryckskon kan regleras medelst kända hydrauliska eller mekaniska anordningar (icke visade), som är anslutna till en stäng 18, vilken är ledbart fästad vid skon 14. Stangen kan även vara krökt för att utöva det önskade trycket pà skon. Tryckskon och pressvalsen, som ovan beskrivits och visats i figurerna l-Z, är av konventionellt utförande och andra anordningar kan användas i enlighet med uppfinningen.The elongate pressing and gripping member according to the invention for dewatering an advanced tissue comprises the gripping means 10 formed by a cylindrical press roll 12, a pressure shoe 14 having a concave surface facing the press roll, and a band 16 arranged to see that it lies one against the press roll surface. The concave surface of the printing shoe has about the same curvature radius as the press roller. The distance between the press roller and the pressure shoe can be adjusted by means of known hydraulic or mechanical devices (not shown), which are connected to a rod 18, which is hingedly attached to the shoe 14. The rod may also be curved to exert the desired pressure on the shoe. The pressure shoe and the press roller, as described above and shown in Figures 1-Z, are of conventional design and other devices may be used in accordance with the invention.
En utföringsform av bandet 16 enligt uppfinningen visas i detalj i figur 3. Bandet 16 innefattar ett i tva skikt vävt underlagstyg 20 med màngtradiga eller spunna stoppningsgarn 21, vilket tyg är impregnerat med ett polymert material 22. Värmehärdande hartser såsom polyuretaner har 457 542 visat sig vara lämpliga impregneringsmaterial. Termoplastiska polymerer sasom polypropen är även användbara.An embodiment of the belt 16 according to the invention is shown in detail in Figure 3. The band 16 comprises a two-layer woven backing fabric 20 with multi-strand or spun upholstery yarn 21, with which fabric is impregnated a polymeric material 22. Thermosetting resins such as polyurethanes have 457 542 proved to be suitable impregnating materials. Thermoplastic polymers as polypropylene are also useful.
Underlagstyget 20 är tillräckligt glest för att möjliggöra impreg- nering vilket eliminerar möjligheten av att mellanrum bildas i det slutliga tyget vid den mot presskon vettande sidan. Sadana mellanrum är icke önskvärda, eftersom de skulle möjliggöra att smörjmedel, som användes mellan bandet och skon, skulle kunna passera genom bandet och förorena filten och den fibrösa vävnaden. Stoppningsgarnen 21 bildar en spärr med tillräckligt lag genomtränglighet, sa att hartsen hindras fran att passera under belëggningen och impregneringen till den med mellanrum försedda sidan. Bandet är utfört ändlöst i sin slutliga form och likformigt i tjocklek.The backing fabric 20 is sufficiently sparse to enable impregnation which eliminates the possibility of gaps being formed in the final the fabric at the side facing the press cone. Such spaces are not desirable because they would allow lubricants to be used between the band and the shoe, could pass through the band and contaminate the blanket and the fibrous tissue. The stuffing yarns 21 form a barrier with sufficient law permeability, said that the resin is prevented from passing during the coating and impregnation of the intermittent side. The band is made endless in its final shape and uniform in thickness.
Bandet maste även utföras sa att det far tillräcklig stabilitet vid användning i en pappersmaskin. Det maste salunda ha längdstabilitet, breddstabilitet och styrbarhet.The strap must also be made so that it has sufficient stability when used in a paper machine. It must thus have longitudinal stability, width stability and controllability.
Den använda termoplastiska hartsen eller värmehërdande hartsen bör ha en torrsubstanshalt av 100%, sa att bubblor icke kan bildas under härdningen av hartsen i bandet, vilket skulle kunna orsaka mellanrum pa den belagda sidan.The thermoplastic resin used or the thermosetting resin should have a dry matter content of 100%, so that bubbles can not form below the hardening of the resin in the strip, which could cause gaps on it coated side.
Bandets sida 17 kan göras slät för kontakten med tryckskon lä.The side 17 of the belt can be made smooth for the contact with the pressure shoe.
Den motsatta sidan innehaller mellanrum till följd av vävningen och fran- varon av impregnering, i vilka mellanrum vätska kan överföras medan väven, filten och bandet passerar genom griporganet.The opposite side contains gaps due to the weaving and fringe the presence of impregnation, at which intervals liquid can be transferred while the fabric, the blanket and strap pass through the gripper.
Ett annat exempel pa den första utföringsformen visas i figur 4.Another example of the first embodiment is shown in Figure 4.
Dess komponenter är liknande de som visas i figur 3. Komponenterna i figur 4 har samma hänvisningsbeteckningar som komponenterna i figur 3 atföljda av primtecken. Bandet 16' i figur 4 är utfört i flera skikt med ett spärrskikt, som bildas av stoppningsgarnen 2l'. Dessa stoppningsgarn 21' kan vara mang- tradiga eller spunna. Bandet belägges och impregneras såsom tidigare beskri- vits, sa att det bildas en slät, ogenomtränglig yta 17' och en yta med mellanrum 18' pa den aterstaende sidan. Bandet 16' användes pa samma sätt som bandet 16.Its components are similar to those shown in Figure 3. The components in Figure 4 have the same reference numerals as the components of Figure 3 followed by prime sign. The band 16 'in Figure 4 is made in several layers with a barrier layer, which formed by the stuffing yarns 2l '. These padding yarns 21 'may be traditional or spun. The tape is coated and impregnated as previously described. white, said to form a smooth, impermeable surface 17 'and a surface with space 18 'on the remaining side. The band 16 'was used in the same way as the band 16.
Vid en andra utföringsform av uppfinningen användes en annan metod att införa det polymera materialet i bandet. Vid denna andra metod pressas polymert material in i ytan. Inträngningsdjupet regleras av tryckkraf- ten och den använda temperaturen. Antingen värmehärdade eller termo- plastiska polymerer kan användas. Termoplastiska polymerer är särskilt fördelaktiga för denna metod, eftersom deras viskositet i smält form kan 457 542 bestämmas av temperaturen. Genom att viskositeten regleras kan inträng- ningsdjupet bestämmas, och nödvändigheten av en spärr i väven elimineras för polymerer med rätt viskositet.In a second embodiment of the invention, another is used method of introducing the polymeric material into the belt. In this second method polymeric material is pressed into the surface. The penetration depth is regulated by the compressive and the temperature used. Either thermoset or thermoset plastic polymers can be used. Thermoplastic polymers are special advantageous for this method, since their viscosity in molten form can 457 542 determined by the temperature. By regulating the viscosity, penetration depth is determined, and the necessity of a barrier in the fabric is eliminated for polymers with the correct viscosity.
Vid denna metod placeras bandet 16 kring ett par valsar. En »av valsarna är en oljeuppvärmd cylinder. Polymert material i bladform med lämplig tjocklek placeras mellan bandet och den uppvärmda cylindern och far _ rotera kring cylindern. Cylindertemperaturen halles vid en niva som önskas för att smälta det polymera materialet till lämplig viskositet. Det tvingas sedan in i bandet av bandets spänning kring cylindern och valsen. En yttre tryckvals kan användas för att åstadkomma ytterligare tryck om sa behövs.In this method, the belt 16 is placed around a pair of rollers. One of the rollers are an oil heated cylinder. Polymer material in sheet form with appropriate thickness is placed between the belt and the heated cylinder and rotate around the cylinder. The cylinder temperature is kept at a desired level to melt the polymeric material to the appropriate viscosity. It is forced then into the belt by the belt tension around the cylinder and the roller. An exterior pressure roller can be used to create additional pressure if needed.
Bladet av polymert material justeras sa att ingen överlappning uppträder i materialet som pressas in i bandet. i Band tillverkade enligt uppfinningen har befunnits ha manga önskvärda egenskaper. De förflyttas lätt över tryckskon och kan överföra tryck fran skon till vävnaden och pressvalsen. Tillräcklig böjlighet erhalles, och banden har visat sig vara opåverkade av smörjmedel, som paföres före inträdet i griporganet. i jämförelse med kända band åstadkommer uppfinningen ett band, som är relativt tunt och lätt. Tjocka band har den nackdelen att de tenderar att flyta medan de befinner sig i griporganet. Ett band med dimensionerna 75Ûx430 cm impregnerat med en värmehärdande harts i enlighet, med uppfinningen väger omkring 90 kg. Ett band av liknande storlek, som har. egenskapen att motsta utbuktning och har en struktur enligt de ovannämnda patenten, väger omkring S40 kg. Till skillnad fran tyngre band kräver bandet enligt uppfinningen icke nagon armering. ' U Tillverkningen av bandet enligt uppfinningen kan utföras ekono- miskt och utan behov av dornar eller autoklaver, vilket begränsar storleken av andra band. Följaktligen kan ett band av godtycklig längd framställas. En väv kan införas i underlaget om sa önskas. Om underlaget icke har vävts ändlöst, göres det därpa ändlöst med användning av konventionell teknik, som användes för att bilda vävar i pappersindustrin.The sheet of polymeric material is adjusted so that no overlap occurs in the material pressed into the belt. in Bands made according to the invention have been found to have many desirable properties. They move easily over the pressure shoe and can transfer pressure from the shoe to the tissue and the press roll. Sufficient flexibility is obtained, and the belts have been found to be unaffected by lubricants previously applied entry into the gripping means. in comparison with known tapes, the invention provides a tape, which is relatively thin and light. Thick bands have the disadvantage that they tend to float while in the gripping means. A band with the dimensions 75Ûx430 cm impregnated with a thermosetting resin in accordance with the invention weighs about 90 kg. A band of similar size, which has. the property of resisting bulging and having a structure according to the above patents, weighs about S40 kg. Unlike heavier belts, the belt requires according to the invention no reinforcement. 'U The manufacture of the belt according to the invention can be carried out economically. mixed and without the need for mandrels or autoclaves, which limits the size of other bands. Consequently, a band of any length can be produced. One fabric can be inserted into the substrate if desired. If the substrate has not been woven endlessly, it is done endlessly there using conventional technology, which was used to form fabrics in the paper industry.
Ett band utfört enligt uppfinningen kan användas tillsammans med anordningen, som visas i figur l. Bandet 16 är beläget mellan tryckskon och pressvalsen. Den släta belagda ytan 17 pa bandet ligger an mot skon. En fibrös vävnad 24 föres mellan en första och en andra filt 26 respektive 27 och införes i griporganet 10. Den sida av bandet, som ligger an mot skon 14, smörjes medelst en smörjanordning 28 belägen framför griporganet. 457 542 Bandet 16 repareras lätt, om ett hal eller annat ytfel skulle uppsta därpa. Den skadade delen rengöres med ett lösningsmedel och en lämplig mängd av beläggningsmaterial tillföres medelst ett knivblad. En värmekanon kan användas för att härda ytan, vilken därefter kan blästras.A belt made according to the invention can be used together with the device shown in Figure 1. The belt 16 is located between the pressure shoe and the press roller. The smooth coated surface 17 of the belt abuts the shoe. One fibrous tissue 24 is passed between a first and a second blanket 26 and 27, respectively is inserted into the gripping member 10. The side of the strap abutting the shoe 14 is lubricated by means of a lubricating device 28 located in front of the gripping means. 457 542 The belt 16 is easily repaired, in the event of a slip or other surface defect uppsta dåpa. The damaged part is cleaned with a solvent and a Appropriate amount of coating material is applied by means of a knife blade. One heat gun can be used to harden the surface, which can then be blasted.
Pa grund av de utmärkta böjningsegenskaperna hos underlaget och att beiäggningen kan hallas vid ett minimum, kommer bandets yta att ha mindre tendens att spricka pa grund av böjningsutmattning. Detta beror pa att till följd av den ringa tjockleken beläggningens ytplan befinner sig pa ett minimalt avstand fran böjningens neutrailager. Detta minskar förlängningen och sammantryckningen vid ytplanet under höjningen.Due to the excellent bending properties of the substrate and that the coating can be kept to a minimum, the surface of the belt will have less tendency to crack due to bending fatigue. This is due to that due to the small thickness the surface plane of the coating is on one minimum distance from the neutral bearing of the bend. This reduces the elongation and the compression at the surface plane during the elevation.
Sasom lätt inses kan bandet, som användes vid uppfinningen, 'innefatta ett underlagstyg utfört av olika polymera material, som har de nödvändiga egenskaperna för användning i pappersmaskiner. Andra material än polyuretan och polypropen kan användas som beläggningsmaterial. Väv- naden av bandet kan även modifieras, fastän ett band i flera skikt är önskvärt för att åstadkomma erforderliga mellanrum.As will be readily appreciated, the belt used in the invention may 'comprise a backing fabric made of various polymeric materials having them necessary properties for use in paper machines. Other materials than polyurethane and polypropylene can be used as coating materials. Fabric- the band of the belt can also be modified, although a multilayer belt is desirable to make the necessary spaces.
