Opfindelsen angår et apparat til påføring af pudsmateriale omfattende en blanding af gips, fyldstof og vand, hvilket apparat omfatter et hus med en indstrømningsåbning, en udstrømningsåbning samt en herimellem anbragt gennemstrømningskanal 5 for den uhærdede pudsmaterialeblanding, som tilføres indstrømningsåbningen under tryk.The invention relates to an apparatus for applying plaster material comprising a mixture of gypsum, filler and water, which apparatus comprises a housing having an inlet opening, an outlet opening and an intermittent flow channel 5 for the uncured plastics material which is supplied to the inlet opening under pressure.
Der kendes forskellige pudsmaterialer indeholdende sandspar-tel/-masse eller gips eller lignende materialer. Disse pudsma-10 terialer er ofte vanskelige at påføre, samtidig med at de ofte stiller krav om en efterbehandling før efterfølgende påføring af maling eller vægbeklædninger, såsom tapet og lignende. Det er endvidere kendt, at der som fyldstof kan anvendes et stenuldsgranulat. Herved opnås et pudsmateriale, som under én ar-15 bejdsgang, uanset tykkelse, kan påføres under dannelse af en pæn og glat overflade, der ikke danner revner eller synker sammen ved sætningen, og som efter normal tids hærdning uden efterbehandling kan behandles med alle kendte typer malinger samt vægbeklædninger, såsom tapet og lignende beklædninger.Various plaster materials are known containing sand asparagus / pulp or plaster or similar materials. These plaster materials are often difficult to apply while often requiring a finishing before subsequent application of paint or wall coverings such as wallpaper and the like. Furthermore, it is known that a granular wool granulate can be used as a filler. Hereby is obtained a plaster material which can be applied in one work, regardless of thickness, to form a neat and smooth surface which does not form cracks or sinks during the setting and which, after normal time curing, can be treated with all known types of paints as well as wall coverings, such as wallpaper and similar coatings.

Det indledningsvis nævnte apparat er ifølge opfindelsen ejendommeligt ved, at huset omfatter et antal ved siden af hinanden indbyrdes adskilte sæt af indstrømningsåbninger, udstrømningsåbninger samt herimellem værende gennemstrømningskanaler 25 med hver sit udslyngningsorgan til udslyngning af pudsmaterialet igennem udstrømningsåbningen, og at der i tilknytning ti 1 udstrømningsåbningerne findes luftdyser til regulering af tykkelsen af den udstrømmende stråle af pudsmateriale.The apparatus mentioned in the invention is characterized in that the housing comprises a plurality of adjacent sets of inflow openings, outflow openings and interconnecting flow ducts 25, each with its own discharge means for discharging the plaster material through the outflow opening and There are air nozzles for controlling the thickness of the ejecting jet material.
30 Herved opnås, at der tilvejebringes et apparat, som har vist sig at være særlig velegnet til brug ved påføring af det omhandlede pudsmateriale, som derved påføres på en let og billig måde, idet der opnås en meget stor arbejdsbesparelse i forhold til hidtil kendte metoder. Apparatet er i stand til at påføre 35 pudsmateriale, således at fladen om ønsket umiddelbart er klar til påføring af maling eller vægbeklædninger.30 This provides an apparatus which has been found to be particularly suitable for use in the application of the present plaster material, which is thereby applied in an easy and inexpensive manner, thereby obtaining a very large labor saving over previously known methods. . The apparatus is capable of applying 35 plaster material so that the surface is immediately ready for application of paint or wall coverings if desired.

2 Særligt hensigtsmæssigt kan ifølge opfindelsen udslyngningsorganerne være koaksialt anbragte skovlhjul, som drives af en fælles motor via en fælles aksel.2 In particular, according to the invention, the ejection means may be coaxially arranged impeller driven by a common motor via a common shaft.
5 Ifølge opfindelsen kan indstrømningsåbningerne fødes via en fælles gennemstrømningstragt, som udvider sig i pudsmaterialets strømningsretning og står i forbindelse med et skaft til manuel bæring af apparatet, og hvorigennem pudsmaterialet tilføres gennemstrømningstragten. Herved opnås, at apparatet 10 bliver særligt enkelt og let lader sig håndtere manuelt. En særlig ensartet fordeling af pudsmaterialet opnås, hvis ifølge opfindelsen hvert sæt af indstrømningsåbninger, udstrømningsåbninger og gennemstrømningskanaler med tilhørende skovlhjul er tildannet forholdsvis smalle set i skovlhjulets aksiale 15 retning, medens indstrømningsåbningernes dimension vinkelret herpå og på tværs af pudsmaterialets strømningsretning er af omtrent samme størrelsesorden og udstrømningsåbningens tilsvarende dimension er flere gange større og omtrent af samme størrelse som skovlhjulets diameter.According to the invention, the inflow openings can be fed via a common throughflow funnel which extends in the direction of flow of the plaster material and communicates with a shaft for manual carrying of the apparatus and through which the plaster material is supplied to the flow hopper. This results in the apparatus 10 being particularly simple and easy to handle manually. A particularly uniform distribution of the plaster material is obtained if, according to the invention, each set of inflow openings, outflow openings and throughflow ducts with associated impeller is formed relatively narrow in the axial direction of the impeller, while the dimension of the inflow openings is approximately perpendicular to the magnitude of the flow of material the corresponding dimension of the outflow opening is several times larger and approximately the same size as the diameter of the impeller.

Det i fig. 1 og 2 viste apparat omfatter en rørformet manøvreringsstang, hvoraf der kun for tydeligheds skyld er vist en del. Denne stang er fortil koblet sammen med apparatets hoved, 10 som er forsynet med det generelle henvisningstal 2. Dette hoved består af en nærmest manøvreringsstangen 1 værende gennemstrømningstragt 3 i hvis indre, der findes en tragtformet gennemstrømningspassage 4, hvis tværsnitsareal udvider sig symmetrisk til begge sider fra den ende, der ligger nærmest manøv-15 rer ingsstangen 1, medens den indsnævres ligeledes i alt væsentligt symmetrisk i retning vinkelret herpå. Fortil er gennemstrømningstragten på ikke nærmere vist måde koblet sammen med en forreste udslyngningsdel, som er forsynet med det generelle henvisningstal 5. Denne udslyngningsdel 5 består af et 20 antal ens elementer 6-20, som ved den ene ende er afsluttet med et endedæksel 21. Disse elementer 6-20, som fortrinsvis er støbt ud i ét af et passende plastmateriale, har ved den ene side hver en udsparing 22. Hvert element 6-20 har en i hovedsagen pladeformet form, og udsparingen 22 har overalt et i ho-25 vedsagen retangulært tværsnit, set i retning vinkelret på det enkelte element 6-20 store flade (se fig. 4). 1 sammenbygget tilstand danner udsparingen 22 i det enkelte element 6-20, således som det især fremgår af fig. 3 og 4, som 30 viser et af elementerne 12 set fra siden, henholdsvis forfra, en forlængelse af den tragtformede gennemstrømningspassage 4 i gennemstrømn i ngstragten 3, idet den enkelte udsparing 22 nærmest gennemstrømningstragten 3 afgrænser en indstrømningsåbning 23 og i den modsatte ende en udstrømningsåbning 24, hvori-35 mellem der f i ndes en gen nemstrømn i ngskanel 25, som er tildannet til optagelse af et roterende skovlhjul 26. Indstrømningsåbningen 23 har et tværsnitsareal, som i retning paralleltThe FIG. 1 and 2 comprise a tubular actuating rod, of which only a portion is shown for clarity. This rod is connected at the front to the head of the apparatus 10, which is provided with the general reference numeral 2. This head consists of a flow-through funnel 3 which is closest to the actuating rod 1, which has a funnel-shaped flow passage 4 whose cross-sectional area extends symmetrically to both sides. from the end nearest the maneuvering rod 1, while also narrowing substantially symmetrically in the direction perpendicular thereto. In addition, the flow funnel is not coupled in a more specific manner with a front projection part which is provided with the general reference number 5. This projection part 5 consists of a number of identical elements 6-20, which at one end are terminated with an end cover 21. These elements 6-20, which are preferably molded into one of a suitable plastic material, each have a recess 22. On each side, each element 6-20 has a generally plate-shaped shape and the recess 22 has a hollow 25 throughout. the rectangular cross section, seen in the direction perpendicular to the individual element 6-20 large surface (see Fig. 4). 1, the recess 22 forms in the individual element 6-20, as can be seen in particular in FIG. 3 and 4, 30 showing one of the elements 12, respectively, from the front, an extension of the funnel-shaped flow passage 4 in the flow-through in the funnel 3, the individual recess 22 closest to the flow-through funnel 3 defining an inlet opening 23 and at the opposite end an outlet opening 24, between which there is a through flow in channel 25 which is formed to receive a rotating impeller 26. The inlet opening 23 has a cross-sectional area which is parallel to the direction.

4 med det enkelte elements 12 store plan, svarer til den til svarende dimension af gennemstrømningspassagen 4 i gennemstrømningstragten 3, og dens endeflader set i denne retning er tildannet flugtende med de tilstødende flader i gennemstrømnings-5 passagen 4. Fra indstrømningsåbningen 23 udvider gennemstrømningskanalen 25 i det enkelte element 12 sig i retning parallelt med elementets store side og i hovedsagen vinkelret på retningen set fra indstrømningsåbningen 23 til udstrømningsåbningen 24. Nærmest indstrømningsåbningen 23 danner gennem-10 strømningskanalen 25 til den ene side (nederst i fig. 3) en bueformet flade 27, som støder tæt op til skovlhjulets 26 periferi, idet udvidelsen går fra en tværsnitsdimension, der er mindre end skovlhjulets 26 radius, til en dimension, der svarer til skovlhjulets diameter. Gennemstrømningskanalen 25 fortis sætter over i udstrømningsåbningen 24 med denne dimension. Modsat den bueformede flade 27 forløber gennemstrømningskanalens 25 afgrænsningsflade 28 med en blød overgang fra indstrømningsåbningen 23 til udstrømningsåbningen 24 nærmest tangentielt til skovlhjulets 26 periferi, således at skovlhjulet 20 26 også her støder tæt op til denne flade 28.4, with the large plane of the individual element 12, corresponds to the corresponding dimension of the flow passage 4 in the flow funnel 3, and its end faces seen in this direction are aligned with the adjacent surfaces in the flow passage 4. From the flow opening 23 the flow channel 25 extends in the individual member 12 faces in a direction parallel to the large side of the member and substantially perpendicular to the direction seen from the inlet port 23 to the outlet port 24. Nearly the inlet port 23 forms the flow channel 25 to one side (bottom of Fig. 3) an arcuate surface 27 , which is adjacent to the circumference of the impeller 26, the extension extending from a cross-sectional dimension smaller than the radius of the impeller 26 to a dimension corresponding to the diameter of the impeller. The flow passage 25 fortis translates into the outlet opening 24 with this dimension. In contrast to the arcuate surface 27, the bounding surface 28 of the flow channel 25 extends with a soft transition from the inlet opening 23 to the outlet opening 24 almost tangentially to the periphery of the impeller 26, so that the impeller 20 26 is adjacent to this surface 28 here as well.
Skovlhjulet 26 er fastgjort på en aksel 29, som strækker sig igennem alle elementerne 6-20 og er fælles for alle de skovlhjul 26, der er anbragt i udsparingerne 22 imellem elementerne 25 6-20. Denne aksel 29 strækker sig ud igennem det an imod ele mentet 20 liggende endedæksel 21 til forbindelse med en motor 57, som kun er vist skematisk i fig. 1 og 2. Denne motor 57 er indrettet til at drive akselen 29 og dermed alle skovlhjulene 26 rundt i en sådan retning, at de enkelte skovle fra at have 30 passeret forbi den bueformede flade 27 i gennemstrømningskanalen 25 passerer på tværs af indstrømningsåbningen 23 og videre frem til umiddelbar nærhed af den nærmest tangentielle afgrænsningsflade 28. Skovlhjulene drejer således rundt i den ved hjælp af en pil 30 i fig. 3 viste retning.The impeller 26 is attached to a shaft 29 which extends through all of the elements 6-20 and is common to all the impeller 26 located in the recesses 22 between the elements 25 6-20. This shaft 29 extends through the end cap 21 adjacent to the element 20 for connection with a motor 57, which is only shown diagrammatically in FIG. 1 and 2. This motor 57 is adapted to drive the shaft 29 and thus all the impeller wheels 26 in such a direction that the individual blades 30 having passed past the arcuate surface 27 of the flow passage 25 pass across the inflow opening 23 and beyond. to the immediate vicinity of the closest tangential boundary surface 28. Thus, the impeller rotates in it by means of an arrow 30 in FIG. 3.
På udslyngningsdelens 5 forside, dvs. den modsat gennemstrømningstragten 3 vendende side, findes der på hver side af rækken 35On the front of the ejection part 5, ie. the opposite side of the flow funnel 3 is provided on each side of the row 35

5 af udstrømningsåbni nger 24, en række af luftdyser, hvilken række strækker sig parallelt med skovlhjulenes 26 aksel 29. Disse dyser dannes af en på hver side af udsparingen 22 anbragt dyse, henholdsvis 31 og 32, således som vist i fig. 3 og g 4. Dyserne består af cylindriske drejelige legemer, henholdsvis 33 og 34, som hver har en radialt gennemgående aflang passage 35 henholdsvis 36. Disse drejelige dyselegemer 33 og 34 er optaget i hertil svarende udsparinger 38 og 59, som udgår fra samme side af elementet 12 som udsparingen 22 og udmunder jO ved elementets 12 forside på samme side, som udstrømningsåbningen 24. De drejelige dyselegemer 33 og 34 har ved hver ende en aksial tap 39 og 40 (i fig. 3), af hvilke den ene er optaget i en koaksialt hermed anbragt boring 41 henholdsvis 42 i samme element 12, medens den anden 59 og 40 er optaget i en j5 tilsvarende boring i det tilstødende element 13 i fig. 4. De drejelige dyselegemer 33 og 34, som er optaget i hvert enkelt af elementerne 6-20 er via deres tappe indbyrdes forbundet, idet tappene har ikke-viste indgrebsdele, som muliggør, at de med hinanden forbundne dyselegemer kan drejes rundt sammen ved 2o påvirkning af en ved udslyngningsdelens 5 ende anbragt knap henholdsvis 43 og 44 (se fig. 1 og 2), som er i indgreb med det nærmeste dyselegeme via endedækslet 21. Bagtil, set i retning af det pågældende elements 12 indstrømningsåbning 23, findes der en luftkanal henholdsvis 45 og 46, som i den ene 25 ende udmunder i udsparingerne henholdsvis 38 og 59 med dyse legemerne 33 og 34 og ved den anden ende står i forbindelse med en igennem alle elementerne gående luftpassage henholdsvis 47 og 48 (vist i fig. 3), som via endedækslet 21 hver for sig står i forbindelse med en tilslutningsstuds henholdsvis 49 og 30 50 (se fig. 1 og 2) for trykluftslanger.5 of the outlet openings 24, a series of nozzles extending parallel to the shaft 29. of the impeller 26 These nozzles are formed by a nozzle, 31 and 32 respectively arranged on each side of the recess 22, as shown in FIG. 3 and g 4. The nozzles consist of cylindrical rotatable bodies 33 and 34, respectively, each of which has a radially continuous elongated passage 35 and 36. These rotatable nozzle bodies 33 and 34 are accommodated in corresponding recesses 38 and 59 starting from the same side. of the element 12 as the recess 22 and opens j0 at the front of the element 12 on the same side as the outlet opening 24. The rotatable nozzle bodies 33 and 34 have at each end an axial pin 39 and 40 (in Fig. 3), one of which is received in a coaxially disposed bore 41 and 42 respectively in the same element 12, while the other 59 and 40 are accommodated in a corresponding bore in the adjacent element 13 of FIG. 4. The pivotal nozzle bodies 33 and 34 accommodated in each of the elements 6-20 are interconnected via their pins, the pins having non-engaged engaging portions which allow the interconnected nozzle bodies to be rotated together at 2o actuating a button located at the end of the ejection member 5 and 43 and 44, respectively (see Figures 1 and 2), which engages the nearest nozzle body via the end cover 21. In the rear, seen in the direction of the inflow opening 23 of the element 12, there is a air ducts 45 and 46 respectively, which at one end end open in the recesses 38 and 59 respectively with the nozzle bodies 33 and 34 and at the other end are connected with an air passage passing through all the elements 47 and 48 respectively (shown in Fig. 3 ), which are connected individually via the end cover 21 to a connecting rod 49 and 30 50 respectively (see Figures 1 and 2) for compressed air hoses.
De enkelte af apparatets dele, såsom manøvreringsstangen 1 og gennemstrømningstragten 3 og udslyngningsdelen 5 samt dennes enkelte elementer, er fastgjort til hinanden ved hjælp af et 35 hvilken som helst passende middel, som ikke er vist nærmere. Sammenkoblingsstederne er samtidig forsynet med passende tætningsorganer, således at de enkelte dele slutter tæt til hinanden.The individual parts of the apparatus, such as the actuating rod 1 and the flow-through funnel 3 and the projecting part 5, as well as the individual elements thereof, are attached to each other by any suitable means which are not shown in detail. At the same time, the coupling sites are provided with suitable sealing means so that the individual parts end up close together.

Ved brug af apparatet ifølge opfindelsen forbindes manøvreringsstangen 1 ved den modsat apparatets hoved 2 beliggende ende med en kilde med pudsmateriale, som ved hjælp af en passende pumpe under tryk presses op igennem manøvreringsstangen 5 1 frem til hovedet 2. Her strømmer pudsmaterialet igennem gen nemstrømningstragten 4 og fordeler sig ud til de enkelte indstrømningsåbninger 23, således som antydet ved hjælp af pile i fig. 2. Herfra strømmer pudsmaterialet frem til mødet med skovlhjulene 26, som drives rundt ved hjælp af motoren 27 og 10 herved bibringer pudsmaterialet en acceleration, som kaster pudsmaterialet ud igennem de tilhørende udstrømningsåbninger 24 og frem imod den vægflade, hvorpå pudsmaterialet skal påføres. Den stråle af pudsmateriale, der kommer ud fra udstrømningsåbningerne, 24 har tendens til at sprede sig ud til 15 begge sider i retning vinkelret på skovl hjulenens fælles akse, hvilket imidlertid undgås ved hjælp af de indstillelige luftdyser 31 og 32, som ved drejning af deres påvirkningsknapper 43 og 44 kan indstilles med den ønskede styrke og i mindre grad også med en ønsket retning. Tykkelsen af det lag af puds-20 materiale, der anbringes på væggen, reguleres også ved hjælp af disse luftdyser 31 og 32, idet jo mere strålen af pudsmateriale koncentreres ved hjælp dysernes 31 og 32 regulering, desto tykkere bliver laget af pudsmateriale.Using the apparatus according to the invention, the actuating rod 1 is connected at the end of the opposite device head 2 to a source of plaster material which, by means of a suitable pump, is pressed up through the actuating rod 5 1 to the head 2. Here the plaster material flows through the flow funnel 4 and distributes out to the individual inflow openings 23, as indicated by arrows in FIG. 2. From there, the plaster material flows up to the meeting with the impeller wheels 26, which are driven around by means of the motor 27 and 10, thereby providing the plaster material with an acceleration, which throws the plaster material out through the associated outflow openings 24 and towards the wall surface to which the plaster material is to be applied. The jet of plaster material coming out of the outflow openings 24 tends to spread to both sides in a direction perpendicular to the common axis of the paddle wheels, which is avoided, however, by the adjustable air nozzles 31 and 32 which, when rotating their influence buttons 43 and 44 can be set with the desired strength and to a lesser extent also with a desired direction. The thickness of the plaster 20 material applied to the wall is also controlled by these air nozzles 31 and 32, the more the beam of plaster material is concentrated by the nozzles 31 and 32 regulation, the thicker the layer of plaster material becomes.
25 Apparatet er beskrevet under henvisning til en foretrukken udførelsesform. Der kan foretages mange ændringer uden at man herved afviger fra opfindelsens idé. F.eks. kan skovlhjulet 26 have en anden form end den viste, idet den blot tjener til at bibringe det under tryk tilførte pudsmateriale en udslyngende 30 acceleration. Antallet af elementer, som samvirker til afgrænsning af gennemstrømningspassagerne, kan variere ligesom de kan være konstrueret med andre dimensioner. Som antydet fremstilles de passende af et passende piastmatera1e, som samtidigt bør være af en sådan art, at apparatet er forholdsvis 35 let at håndtere af brugeren, som skal holde manøvreringsstan gen i hænderne.The apparatus is described with reference to a preferred embodiment. Many changes can be made without departing from the idea of the invention. Eg. For example, the impeller 26 may be of a different shape from that shown, merely serving to impart a throbbing 30 acceleration to the pressurized material. The number of elements that cooperate to define the flow passages may vary as they may be constructed with other dimensions. As indicated, they are conveniently made of a suitable plastic material, which should at the same time be of such a nature that the apparatus is relatively easy to handle by the user, who must hold the actuating control in his hands.
