Valse med ytter- og innermantel.Roller with outer and inner jacket.
Foreliggende oppfinnelse angår slike valser som består avThe present invention relates to such rollers which consist of
en ytter- og en innermantel samt et ringformet mellomrom mellom mantlene, tilsluttet innløp og utløp for et i mellomrommet strøm-mende gass- eller væskeformet medium, og forsynt med en ledeskinne for styring av mediets strømning gjennom det ringformede mellomrom. Slike valser brukes i det vesentlige for plastbelegging av papir, an outer and an inner jacket as well as an annular space between the jackets, connected to the inlet and outlet for a gaseous or liquid medium flowing in the space, and provided with a guide rail for controlling the flow of the medium through the annular space. Such rollers are mainly used for plastic coating of paper,
men kan også finne anvendelse ved valsing av plastfolier, kjøle-valsing av ekstrudert gummi, valsing i papirmaskiner og limpressing i forbindelse med valsing. but can also be used in rolling plastic foils, cold rolling extruded rubber, rolling in paper machines and adhesive pressing in connection with rolling.
Porat det skal oppnås en god•varmeoverførende effekt mellom det mediet som strømmer gjennom det ringformede mellomrommet og yttermantelen, er det i mellomrommet anbragt en skruelinjeformet styreflens som tvinger mediet til å strømme langs en lengere vei gjennom mellomrommet. In order to achieve a good heat transfer effect between the medium that flows through the annular space and the outer casing, a helical guide flange is placed in the space, which forces the medium to flow along a longer path through the space.
Hensikten med foreliggende oppfinnelse er å anordne den skruelinjeformede styreflensen på en slik måte at man oppnår en rime-, lig fremstillingsmetode for valsen, får god tetning mellom styreflens og yttermantel og innermantel, samtidig som det skal være mulig etter behov å skifte ut en yttermantel med en annen, uten å behøve bytte innermantel, styreflens eller lagertappene. The purpose of the present invention is to arrange the helical guide flange in such a way that a reasonable, reasonable manufacturing method for the roller is achieved, a good seal is obtained between the guide flange and the outer jacket and inner jacket, while at the same time it should be possible to replace an outer jacket with another, without having to change the inner shell, guide flange or bearing studs.
Dette oppnås ifølge oppfinnelsen ved en valse, bestående av en ytter- og en innermantel samt et ringformet mellomrom mellom mantlene, tilsluttet innløp og utløp for et i mellomrommet strømmende gass- eller væskeformet medium, og forsynt med en på høykant stilt skruelinjeformet styreskinne for styring av mediets strømning gjennom det ringformede mellomrommet, og det karakteristiske ved oppfinnelsen består i at det utvendig omkring innermantelen er anbragt - et bærelag i hvilket styreskinnen griper inn med sin radielt sett indre kant, hvilken styreskinne er innspent mellom bærelaget og yttermantelen slik at denne skinne understøttes ved kontaktstedet mellom yttermantelen og skinnen. According to the invention, this is achieved by a roller, consisting of an outer and an inner mantle as well as an annular space between the mantles, connected to the inlet and outlet for a gaseous or liquid medium flowing in the space, and provided with a helical guide rail placed on a high edge for controlling the flow of the medium through the annular space, and the characteristic of the invention consists in the fact that it is arranged on the outside around the inner jacket - a support layer in which the guide rail engages with its radially inner edge, which guide rail is clamped between the support layer and the outer jacket so that this rail is supported by the point of contact between the outer casing and the rail.
Ved en foretrukket utførelse for oppfinnelsen utgjøres bærelaget av et fortrinnsvis elastisk, deformerbart materiale.I en videreutvikling av oppfinnelsen består bærelaget av en skruelinjeformet holder som er forsynt med spor for inngrep av den radielt sett indre kanten på den kantstilte styreskinnen. Fortrinnsvis er den skruelinjeformede holderen hul og anordnet til å blåses opp'ved hjelp av trykkluft, vann, olje eller.lignende. Ifølge oppfinnelsen kan holderen, være forsynt med et med metallskinne forsterket spor for opptagelse av den radielt sett indre kant på styreskinnen. Videre kan, ifølge en videreutvikling av oppfinnelsen, yttermantelen 1 på innsiden være forsynt med et skruelinjeformet spor for opptagelse av den radielt sett ytre kanten av styreskinnen. In a preferred embodiment of the invention, the support layer is made of a preferably elastic, deformable material. In a further development of the invention, the support layer consists of a helical holder which is provided with grooves for engagement of the radially inner edge of the edged guide rail. Preferably, the helical holder is hollow and arranged to be inflated by means of compressed air, water, oil or the like. According to the invention, the holder can be provided with a groove reinforced with a metal rail for accommodating the radially inner edge of the guide rail. Furthermore, according to a further development of the invention, the outer jacket 1 can be provided on the inside with a helical groove for receiving the radially outer edge of the guide rail.
Ved fremstilling av valsen forsynes, ifølge oppfinnelsen, innermantelen utvendig hensiktsmessig med et bærelag for styreskinnen som anbringes omkring innermantelen slik at den radielt sett indre. kanten av skinnen griper inn i bærelaget, og den ytre diameter av den på denne måte dannede skinnen får en ytre diameter som i noen grad (f.eks. 1-3 mm) overstiger innerdiameteren på yttermantelen, hvor-etter denne skyves inn på styreskinnen, slik at dennes viklinger bøyes noe til siden og dermed med et visst radielt trykk ligger an innvendig mot yttermantelen. På grunn av at skinnen i anbringelsesstil-lingen med en viss fjærspenning presses mot innsiden av yttermantelen kommer denne langs hele kontaktstedet til å bli effektivt understøttet, hvorfor det blir mulig å velge en platetykkelse på yttermantelen som er mindre enn den som man tidligere måtte bruke. Takket være skinnens fjærende anlegg mot yttermantelen oppnås også en tilstrekkelig tetning til at det mediet som renner gjennom det nevnte ringformede mellomrom følger styreskinnens viklinger. Den gode kontakten mellom skinnen og yttermantelen bidrar til en god varmeoverføring fra skinnen til yttermantelen, eller når valsen brukes som kjølevalse fra yttermantelen til skinnen og det strømmende kjølemediet. In the manufacture of the roller, according to the invention, the inner jacket is appropriately provided on the outside with a support layer for the guide rail which is placed around the inner jacket so that it is radially inside. the edge of the rail engages in the support layer, and the outer diameter of the rail formed in this way has an outer diameter which to some extent (e.g. 1-3 mm) exceeds the inner diameter of the outer jacket, after which this is pushed onto the guide rail , so that its windings are bent slightly to the side and thus, with a certain radial pressure, rest on the inside against the outer casing. Due to the fact that the rail in the attachment position is pressed against the inside of the outer shell with a certain spring tension, this will be effectively supported along the entire point of contact, which is why it becomes possible to choose a plate thickness on the outer shell that is smaller than that which was previously used. Thanks to the resilient contact of the rail against the outer casing, a sufficient seal is also achieved so that the medium flowing through the aforementioned annular space follows the windings of the guide rail. The good contact between the rail and the outer jacket contributes to a good heat transfer from the rail to the outer jacket, or when the roller is used as a cooling roller from the outer jacket to the rail and the flowing coolant.
I det følgende skal oppfinnelsen forklares ved hjelp av tegningen der In the following, the invention will be explained with the help of the drawing there
fig. 1 er et delvis snitt av en valse ifølge oppfinnelsen og fig. 2 er et innriss av valsen. Fig. 3 viser i noe større målestokk et snitt gjennom den ene enden av valsen under sammenstillingen. Fig. i| er et delvis i snitt vist sideriss av en valse ifølge en annen utførelsesform av oppfinnelsen, og fig. 1 is a partial section of a roller according to the invention and fig. 2 is an outline of the roller. Fig. 3 shows, on a somewhat larger scale, a section through one end of the roller during assembly. Fig. i| is a partially sectional side view of a roller according to another embodiment of the invention, and
fig. 5 viser i større målestokk en del av valsen i lengde-snitt. fig. 5 shows on a larger scale part of the roller in longitudinal section.
Fig. 6 er et perspektivisk riss av yttermantelen som viser anbringelsen av styreskinnen på det skruelinjeformede organet. Fig. 6 is a perspective view of the outer casing showing the placement of the guide rail on the helical member.
Den på tegningen viste valse er tenkt utført som en kjøle-valse med en ytterdiameter på f.eks. 500 mm og med vann som kjøle-medium. Valsens yttermantel 1 og innermantel 2 er tenkt utført av. relativt tynn plate (med en tykkelse på f.eks. H- 6 mm) som er rullet til sylinderform med en sveiset lengdeskjøt. Skjøten slipes etter sveisingen slik at mantlene 1,2 blir jevne utvendig. Eventuelt kan mantelen etter sveisingen gjennomgå en rullingsoperasjon, slik at de blir praktisk talt helsylinderiske. Ved innermantelen .2 festes, hensiktsmessig ved sveising, valsens akseltapper 3S som er hule, ved hjelp av eker 4, slik at innermantelens innside blir tilgjengelig mellom dem. Akseltappene 3 er forsynt med en boring 5 med hvilken de kommuniserer med det ringformede mellomrom 6 mellom mantelene 1 og 2 ved hjelp av rør 7 som også tjener som eker. The roller shown in the drawing is designed as a cooling roller with an outer diameter of e.g. 500 mm and with water as cooling medium. The roller's outer jacket 1 and inner jacket 2 are thought to be made of. relatively thin plate (with a thickness of e.g. H- 6 mm) which is rolled into a cylindrical shape with a welded longitudinal joint. The joint is ground after welding so that the outer casings 1,2 are smooth. Optionally, after welding, the mantle can undergo a rolling operation, so that they become practically completely cylindrical. At the inner casing .2, the roller's shaft pins 3S, which are hollow, are attached, suitably by welding, by means of spokes 4, so that the inside of the inner casing is accessible between them. The axle pins 3 are provided with a bore 5 with which they communicate with the annular space 6 between the casings 1 and 2 by means of tubes 7 which also serve as spokes.
I mellomrommet 6 mellom mantelene 1 og 2 er det ved valsens begge ender innført to fjærringer 8,9 som er forsynt med en tverr-gående sliss og som har forskjellig diametre. Disse ringene er frem-stilt av stål eller lignende materiale. Den største fjærringen 8 har en utvendig diameter som bare er ubetydelig mindre enn ytter-måntelens 1 indre diameter. Den minste fjærringen 9 har en indre diameter som bare ubetydelig overstiger innermantelens 2 ytre diameter. Pjærringenes 8,9 radielt mot hverandre vendende flater 10, resp. 11 er koniske, slik at ringenes aksielt indre ende blir tyk-kere enn deres ytre ende. I mellomrommet mellom fjærringene 8,9 er det innført en tetningsring 12, hvis radielt ytre og indre flater er koniske, med en konisitet som stemmer overens med konisiteten på flatene 10, 11 på fjærringene 8,9. Ringen 12 er forsynt med et an-tall boringer 13, hvis akselinje er parallell med valsens lengde-akse. Boringene 13 gjennomløpes med god klaring av bolter 15 med hode 14 som er innskrubare i en mutterring 16. Mellom mutterringen 16 og fjærringene 8,9 er det anbragt en ringformet tetning 17 av gummi eller annet hensiktsmessig elastisk materiale. In the space 6 between the mantles 1 and 2, two spring rings 8,9 are inserted at both ends of the roller, which are provided with a transverse slot and have different diameters. These rings are made of steel or similar material. The largest spring ring 8 has an outer diameter which is only slightly smaller than the inner diameter of the outer ring 1. The smallest spring ring 9 has an inner diameter that only slightly exceeds the outer diameter of the inner jacket 2. The radially facing surfaces 10 of the pier rings 8,9, resp. 11 are conical, so that the axial inner end of the rings is thicker than their outer end. In the space between the spring rings 8,9, a sealing ring 12 is inserted, the radially outer and inner surfaces of which are conical, with a conicity that corresponds to the conicity of the surfaces 10, 11 of the spring rings 8,9. The ring 12 is provided with a number of bores 13, the axis line of which is parallel to the longitudinal axis of the roller. The bores 13 are passed through with good clearance by bolts 15 with heads 14 which can be screwed into a nut ring 16. Between the nut ring 16 and the spring rings 8,9, an annular seal 17 of rubber or other suitable elastic material is placed.
Utvendig omkring innermantelen 2 er det ifølge fig. 1 og 2 anbragt et bærelag 18 av et hensiktsmessig og relativt sterkt og også varmeisolerende materiale. Et slikt materiale er f.eks.glassfiberarmert plast, f.eks. polyesterplast. Denne vikles opp i bånd omkring innermantelene slik at det dannes en relativt slett, sylinderformet mantel. Omkring denne plastmantelen vikles det en på høykant stilt strimmel av stål, hensiktsmessig, fjærstål, slik at den strekker seg skruelinjeformet fra valsens ene ende til den andre. Denne styreskinne 19 gis en utvendig diameter som overstiger yttermantel ens 1 indre diameter noe, f.eks. 1-3 mm. I mellomrommet mellom nærbeliggende viklinger og styreskinnen anbringes det ytterligere glassfiberarmert plast, slik at skinnen med sin radielt sett indre kant 20 blir innleiret i bærelaget 18. On the outside around the inner jacket 2, according to fig. 1 and 2 placed a support layer 18 of an appropriate and relatively strong and also heat-insulating material. Such a material is, for example, fiberglass reinforced plastic, e.g. polyester plastic. This is wound up in ribbons around the inner sheaths so that a relatively smooth, cylindrical sheath is formed. An upright strip of steel, preferably spring steel, is wound around this plastic jacket, so that it extends helically from one end of the roller to the other. This guide rail 19 is given an external diameter that exceeds the outer casing's 1 internal diameter somewhat, e.g. 1-3 mm. In the space between nearby windings and the guide rail, additional glass fiber reinforced plastic is placed, so that the rail with its radially inner edge 20 is embedded in the support layer 18.
Ved valsens sammensetning forskyves yttermantelen 1 innover innermantelen 2 (se fig. 3), idet styreskinnens 19 viklinger bøyes noe fjærende til siden. Etterat yttermantelen er forskjøvet til sin nøyaktige stilling på innermantelen 2 (fig. 1), i hvilken stilling styreskinnen 19 med en viss fjærspenning presses mot innsiden av yttermantelen 1 trekkes boltene 15 til. Derved bringes ringene 8 og 9"til å ekspandere mot yttermantelen 1 resp. innermantelen 2 samtidig som det oppnås nødvendig tetning ved valsens ender ved komprimering av tetningsringene. 17. Kjølemediet strømmer, slik som angitt med piler i fig. 1, inn gjennom den ene akseltappen 3, i spiral gjennom mellomrommet 6 mellom bærelaget 18 og yttermantelen 1, samt ut gjennom den motsatte akseltappen 3. Den av bærelaget 18, styreskinnen 19 og yttermantelen 1 begrensede kanal kan gis relativt lite tverrsnitt, hvorfor strømningshastigheten på kjølemediet kan gjøres relativt høy. På grunn av dette og den gode kontakten mellom styreskinnen 19 og yttermantelen 1 blir varmeav-gangen til kjølemediet god. When the roller is assembled, the outer casing 1 is displaced inwards into the inner casing 2 (see fig. 3), as the windings of the guide rail 19 are bent somewhat springily to the side. After the outer shell has been moved to its exact position on the inner shell 2 (fig. 1), in which position the guide rail 19 is pressed against the inside of the outer shell 1 with a certain spring tension, the bolts 15 are tightened. Thereby, the rings 8 and 9" are caused to expand towards the outer jacket 1 and the inner jacket 2, at the same time as the necessary sealing is achieved at the ends of the roller by compression of the sealing rings. 17. The cooling medium flows, as indicated by arrows in Fig. 1, through one the shaft pin 3, in a spiral through the space 6 between the bearing layer 18 and the outer casing 1, as well as out through the opposite shaft pin 3. The channel limited by the bearing layer 18, the guide rail 19 and the outer casing 1 can be given a relatively small cross-section, which is why the flow rate of the coolant can be made relatively high. Because of this and the good contact between the guide rail 19 and the outer jacket 1, the heat transfer to the coolant is good.
Ved utbytte av yttermantelen 1 trekkes denne av i samme retning som den tres inn på innermantelen 2. When replacing the outer sheath 1, this is pulled off in the same direction as it is threaded onto the inner sheath 2.
Ifølge den i fig. 4 til 6 viste utførelsesform kan bærelaget 18 bestå av skruelinjeformede organer 21. Disse organene 21 kan utgjøres av mot hverandre lagte ringer eller, slik som vist i fig. 6, av en skruelinjeformet viklet slange, som anbringes på den indre mantelen 2. Styreskinnen 19 støtter seg med sin radielt indre kant 20 i et spor 22 i det skruelinjeformede organ 21 (slangen). Sporet 22 er hensiktsmessig forsterket med en i tverrsnitt vesentlig U-formet metallskinne 23. Med sin radielt -sett ytre kant 24 er skinnen 19 innført i et skruelinjeformet spor 25 på innsiden av yttermantelen 1. According to the one in fig. 4 to 6 embodiment, the support layer 18 can consist of helically shaped bodies 21. These bodies 21 can be made up of rings placed against each other or, as shown in fig. 6, of a helically wound hose, which is placed on the inner jacket 2. The guide rail 19 rests with its radially inner edge 20 in a groove 22 in the helically shaped body 21 (the hose). The track 22 is suitably reinforced with a substantially U-shaped metal rail 23 in cross-section. With its radially viewed outer edge 24, the rail 19 is inserted into a helical groove 25 on the inside of the outer casing 1.
Ved montering går man frem-slik (se i denne forbindelse særlig på fig. 6) at styreskinnen 19 først skrues inn i yttermantelen 1 og deretter "skrues" den skruelinjeformede slangen 26 inn slik at skinnen 19 griper med sin radielt sett indre kant inn i sporet i slangen. Slangen 26 er ved monteringen hensiktsmessig ikke under innvendig trykk, men er avslappet slik at innermantelen 2 lett kan skyves inn. Ved en innblåsningsventil 27 (se fig. 5) fylles slangens 26 indre 28 med et trykkmedium, f.eks. trykkluft eller hydraulisk medium så som vann eller olje, Derved presses sporet 22 med forsterkningsskinnen 23 mot den radielt sett indre kanten 20 av styreskinnen 19, og denne i sin tur presses med sin radielt sett ytre kant 24 mot yttermantelen 1, slik at denne oppnår bedre innvendig støtte. Ved denne pressing oppnås også forbedret tetting ved såvel den ytre kant 24 som den indre kant 20 av skinnen 19j slik at det mediet som strømmer gjennom mellomrommet 6 tvinges til å følge den skruelinjeformede banen som dannes av styreskinnen 19 mellom mantelene 1 og 2. Det forekommer ikke noe lekkasje mellom de forskjellige viklingene av banen. For å sikre rett stilling på de skruelinjeformede omdreiningene av slangen 26 på innermantelen 2 kan man anbringe festeskruer 29 med muttere 30 på skruenes indre ende. Man kan også tenke seg alternativ ved hjelp av fjærringene 9 During assembly, proceed in such a way (see in this connection in particular fig. 6) that the guide rail 19 is first screwed into the outer casing 1 and then the helical hose 26 is "screwed in" so that the rail 19 engages with its radially inner edge into the groove in the hose. The hose 26 is suitably not under internal pressure during assembly, but is relaxed so that the inner jacket 2 can be pushed in easily. With a blow-in valve 27 (see fig. 5), the inner 28 of the hose 26 is filled with a pressure medium, e.g. compressed air or hydraulic medium such as water or oil, thereby pressing the groove 22 with the reinforcement rail 23 against the radially seen inner edge 20 of the guide rail 19, and this in turn is pressed with its radially seen outer edge 24 against the outer shell 1, so that this achieves better internal support. With this pressing, improved sealing is also achieved at both the outer edge 24 and the inner edge 20 of the rail 19j so that the medium flowing through the space 6 is forced to follow the helical path formed by the guide rail 19 between the casings 1 and 2. It occurs no leakage between the different windings of the track. To ensure the correct position of the helical turns of the hose 26 on the inner casing 2, fastening screws 29 with nuts 30 can be placed on the inner end of the screws. You can also think of an alternative using the spring rings 9
å oppnå en slik støtte for endene av det skruelinjeformede organ 21 ved valsens ender at alle omdreiningene holdes i stilling på innermantelen 2, ifall valsens ene gavl skal monteres først etter fyl-ling med trykkmediet. I dette tilfellet kan festeskruene 29 spares og tetningen derved forbedres. to achieve such a support for the ends of the helical body 21 at the ends of the roller that all the revolutions are kept in position on the inner casing 2, if one end of the roller is to be mounted only after filling with the pressure medium. In this case, the fastening screws 29 can be saved and the seal thereby improved.
De viste og beskrevne utførelsesformene er å betrakte som eksempler og valsens forskjellige deler kan konstruktivt forandres på en rekke måter innen rammen for påstandene. På tegningene er valsen vist forsynt med bare én styreskinne 19. Det kan imidlertid komme på tale med flere slike, slik at det strekker seg flere kanaler i spiral innenfor yttermantelen 1. The shown and described embodiments are to be regarded as examples and the different parts of the roller can be constructively changed in a number of ways within the scope of the claims. In the drawings, the roller is shown equipped with only one guide rail 19. However, there may be several such, so that several channels extend in a spiral within the outer casing 1.
Istedetfor stål eller metall kan styreskinnen 19 være ut-ført med en strimmel av fjærende plast, f.eks. polyten. Bærelaget 18 kan også være utført av gummi. Oppfinnelsen kan naturligvis også tillempes ved varmevalser, der det varmeoverførende mediet kan utgjøres av varmt vann eller damp. For de skruelinjeformede organene 21 kan det velges gummi av bildedekkskvalitet eller med en hårdhet som er noe større enn på en slik kvalitet, f.eks. 70° shore. Videre kan man tenke seg en eller annen plast som i mange tilfeller med fordel kan glassfiberarmeres. Det skruelinjeformede organet eller organene behøver ikke være hule, men en slik utformning letter monteringen ettersom organene i avslappet tilstand er lettere å Instead of steel or metal, the guide rail 19 can be made with a strip of springy plastic, e.g. polythene. The support layer 18 can also be made of rubber. The invention can of course also be applied to heat rollers, where the heat-transferring medium can be made up of hot water or steam. For the helical members 21, rubber of tire quality or with a hardness somewhat greater than that of such quality can be selected, e.g. 70° shore. Furthermore, one can think of some plastic which in many cases can advantageously be glass fiber reinforced. The helical member or members need not be hollow, but such a design facilitates assembly as the members in a relaxed state are easier to
