Description

Målemaskin for treflis eller lignende. Measuring machine for wood chips or similar.

Oppfinnelsen angår en målemaskin for treflis e. 1. av den art som omfatter i forhold til hverandre om .en aksel roterbare og i akselretningen i forhold til hverandre innstillbare maleorganer, mellom hvilke det foreligger en i tverr-retningen avsmalnende grovmalingssone og en på tvers av rotasjonsakselen forløpende finmalingssone, som grovmalingssonen går over i med jevn bøyning. The invention relates to a measuring machine for wood chips e. 1. of the kind which includes grinding members rotatable in relation to each other about an axis and adjustable in the direction of the axis in relation to each other, between which there is a coarse grinding zone tapering in the transverse direction and a crosswise the rotation axis runs through the fine grinding zone, into which the coarse grinding zone transitions with a smooth bend.

Ved hittil kjente målemaskiner med en grovmalingssone og en, sett i materetningen, etter denne beliggende finmalingssone, har grovmalingssonens ytre begrensnings-vegg vært utført konisk avsmalnende i materetningen. En slik utforming er imidlertid meget uheldig ved målemaskiner for treflis og lignende gods, fordi ytterveggen, på grunn av den relativt høye rotasjons-hastigheten og den derav betingete tilsvarende store sentrifugalkraften, vil komme til å motsette seg malegodsets bevegelse gjennom grovmalningssonen. Det er videre tidligere kjent å utføre grovmalningssonen med en yttervegg som vider seg konisk utover, idet det inn gjennom ytterveggen er rettet et roterbart konisk maleorgan med slik form at sonens tverrsnitt likevel av-smalner i materetningen. Ved disse tidligere kjente målemaskiner har imidlertid maleorganets koniske maleoverflate dannet en forholdsvis stor vinkel med organets rotasjonsakse, slik at grovmalningssonen blir kort. Dette forhold har ingen betyd-ning ved maling av visse materialer, men innebærer en stor ulempe når det gjelder maling av treflis og lignende gods. In previously known measuring machines with a coarse grinding zone and a fine grinding zone located after this, seen in the feed direction, the outer limiting wall of the coarse grinding zone has been made conically tapering in the feed direction. However, such a design is very unfortunate for measuring machines for wood chips and similar goods, because the outer wall, due to the relatively high rotation speed and the resulting correspondingly large centrifugal force, will oppose the movement of the grinding material through the coarse grinding zone. It is also previously known to perform the coarse grinding zone with an outer wall that widens conically outwards, with a rotatable conical grinding member of such a shape that the cross-section of the zone nevertheless tapers in the feed direction is directed into the outer wall. In the case of these previously known measuring machines, however, the grinding body's conical grinding surface has formed a relatively large angle with the body's axis of rotation, so that the coarse grinding zone is short. This ratio has no significance when painting certain materials, but entails a major disadvantage when it comes to painting wood chips and similar goods.

Formålet for oppfinnelsen er å elimi-nere de ulemper og mangler som er nevnt ovenfor. Dette oppnås ved at grovmalningssonens maleorganer er slik utformet, at linjen eller generatrisen for den tilnærmet koniske ytre maleoverflaten divergerer i matningsretningen fra rotasjonsakse! under en vinkel av størrelsesorden 30° og at tangenter til den samvirkende indre maleoverflatens S-formete bøyete generatrise danner en vinkel på ca. 3° med den ytre maleoverflatens generatrise. The purpose of the invention is to eliminate the disadvantages and shortcomings mentioned above. This is achieved by the rough grinding zone's grinding bodies being designed in such a way that the line or generatrix for the approximately conical outer grinding surface diverges in the feed direction from the axis of rotation! under an angle of the order of 30° and that tangents to the S-shaped bent generatrix of the cooperating internal painting surface form an angle of approx. 3° with the generatrix of the outer painting surface.

Oppfinnelsen skal nå beskrives nær-mere under henvisning til vedlagte tegning som viser en eksempelvis utførelsesform for en målemaskin ifølge oppfinnelsen med vertikal aksel. The invention will now be described in more detail with reference to the attached drawing which shows an exemplary embodiment of a measuring machine according to the invention with a vertical shaft.

På tegningen betegner 10 målemaski-nens hermetisk lukkete hus og 11 det i dette anbrakte roterbare maleorgan, som i øver-enden bæres av en gjennom malehusets bunn innført vertikal aksel 12. Materialet som skal males presses inn i malehusets 10 øvre del ved hjelp av en maskindrevet horisontal matningsskrue 13 fra en matnings-trakt 14. Ved hjelp av en rørtilkopling 15 kan malehusets 10 indre settes i forbindelse med en ikke vist damptrykkkilde. Med tallet 16 er betegnet en pakningsboks, som tetter mot akselen 12. In the drawing, 10 denotes the hermetically sealed housing of the measuring machine and 11 the rotatable grinding member placed in this, which is supported at the upper end by a vertical shaft 12 introduced through the bottom of the grinding housing. The material to be ground is pressed into the upper part of the grinding housing 10 by means of a machine-driven horizontal feed screw 13 from a feed funnel 14. By means of a pipe connection 15, the inside of the grinding house 10 can be connected to a steam pressure source, not shown. The number 16 denotes a packing box, which seals against the shaft 12.

Utenfor malehuset 10 er den vertikale akselen 12 roterbart lagret dels i et øvre radialkulelager 17, som er glidbart i aksiell retning i en fast styrehylse 18, dels i et nedre radialkulelager 19, som er anbrakt i et lagerhus 20, som er glidbart i aksiell retning i en fast styrehylse 21. Den nedre enden av maleorganakselen støter ved hjelp av et i lagerhusets 20 anordnet aksialkule-lager 22 mot enden av den korte armen på en toarmet vektstang eller hevstang 23, som er dreibar om en fast horisontal aksel-tapp 24. Ved enden av vektstangens 23 lan-ge arm påvirkes vektstangen av en vertikal stang 25, som ved hjelp av en fjær 26 presses i retning nedover. Spenningen i fjæren 26, som med sin nedre ende ligger an mot en fast krave 27 på stangen 25 og med sin øvre ende mot undersiden av en reguleringsskrue 28, som fritt omslutter stangen, kan endres ved dreining av skruen ved hjelp av et ratt 29. I stedet for den beskrevne trykkanordningen i forbindelse med en fjær kan det anvendes en trykk-mekanisme 30 av hydraulisk type. Maleorganakselen 12 drives av en elektrisk mo-tor 31 over en removerføring 32. Outside the grinding housing 10, the vertical shaft 12 is rotatably supported partly in an upper radial ball bearing 17, which is slidable in the axial direction in a fixed guide sleeve 18, and partly in a lower radial ball bearing 19, which is placed in a bearing housing 20, which is slidable in the axial direction in a fixed guide sleeve 21. The lower end of the grinding member shaft abuts with the help of an axial ball bearing 22 arranged in the bearing housing 20 against the end of the short arm of a two-armed lever or lever 23, which is rotatable about a fixed horizontal axle pin 24. At the end of the long arm of the barbell 23, the barbell is affected by a vertical bar 25, which is pressed downwards by means of a spring 26. The tension in the spring 26, which rests with its lower end against a fixed collar 27 on the rod 25 and with its upper end against the underside of an adjusting screw 28, which freely surrounds the rod, can be changed by turning the screw with the help of a steering wheel 29. Instead of the pressure device described in connection with a spring, a pressure mechanism 30 of hydraulic type can be used. The grinding organ shaft 12 is driven by an electric motor 31 via a belt transmission 32.

Som det fremgår av tegningen er det sentrale partiet av malehusets 10 øver del utformet som en konus med relativt liten toppvinkel, dvs. den koniske flatens generatrise danner en liten vinkel med den vertikale rotasjonsakselen. En hensiktsmessig størrelse av denne vinkelen er ca. 30°. De tilsvarende delene av det roterbare maleorganet 11 er også tilnærmet konisk utformet, men maleoverflaten danner en større vinkel med rotasjonsakselen, slik at det mellom den koniske malehusveggen og det roterbare maleorganets koniske del dannes en formalingssone 33, som under en vinkel på ca. 3° konvergerer fra innmat-ningsenden for materialet som skal mates. Den etter formalingssonen 33 anordnete finmalingssone dannes mellom to ringfor-mete maleorganer 34 og 35, som er løsbart festet til malehuset 10, henholdsvis ved en skrått nedover og utover løpende forleng-ning av det roterbare maleorganet 11, og med plane maleoverflater, som danner rett vinkel med rotasjonsakselen. Det er klart, at finmalingsgraden til det ut av måle-maskinen utmatede materiale bestemmes av avstanden mellom de i forhold til rotasjonsakselen tversgående maleflåtene på maleorganet 34 og 35, og videre er det åpenbart at en endring av denne avstand ved aksiell forskyvning av maleorganet 11 vil bare medføre en helt ubetydelig endring i avstanden mellom maleoverflatene i formalingssonen. As can be seen from the drawing, the central part of the upper part of the paint housing 10 is designed as a cone with a relatively small top angle, i.e. the generatrix of the conical surface forms a small angle with the vertical axis of rotation. An appropriate size of this angle is approx. 30°. The corresponding parts of the rotatable grinding member 11 are also approximately conically designed, but the grinding surface forms a larger angle with the axis of rotation, so that between the conical grinding housing wall and the conical part of the rotatable grinding member a grinding zone 33 is formed, which at an angle of approx. 3° converges from the feed end for the material to be fed. The fine grinding zone arranged after the grinding zone 33 is formed between two ring-shaped grinding bodies 34 and 35, which are releasably attached to the grinding housing 10, respectively by an obliquely downward and outwardly extending extension of the rotatable grinding body 11, and with flat grinding surfaces, which form straight angle with the axis of rotation. It is clear that the degree of fine grinding of the material discharged from the measuring machine is determined by the distance between the grinding floats on the grinding member 34 and 35 transverse to the axis of rotation, and furthermore it is obvious that a change in this distance by axial displacement of the grinding member 11 will only result in a completely insignificant change in the distance between the grinding surfaces in the grinding zone.

Maleoverflatene i formalingssonen 33 kan på i og for seg kjent måte være forsynt med spiralformete eller på annen hensiktsmessig måte forløpende riller eller andre forhøyninger, og også de tverstilte maleoverflatene på maleorganene 34, 35 i fin-malingssonen kan være riflete eller gjort ujevne på annen måte for å forbedre male-effekten. For kontinuerlig utmatning av den ferdigmalte massen ut av malehuset 10 kan det anvendes en utmatningsventil av en hvilken som helst hensiktsmessig type. Særlig fordelaktig viser det seg å anvende en utmatningsventil av den type som vises og beskrives i svensk patent nr. 161 663. The grinding surfaces in the grinding zone 33 can, in a manner known per se, be provided with spiral-shaped or in another suitable way continuous grooves or other elevations, and also the transverse grinding surfaces of the grinding bodies 34, 35 in the fine-grinding zone can be grooved or made uneven in some other way to improve the painting effect. A discharge valve of any appropriate type can be used for continuous discharge of the finished ground mass out of the grinding housing 10. It turns out to be particularly advantageous to use a discharge valve of the type shown and described in Swedish patent no. 161 663.

Det vil forstås at oppfinnelsen ikke nødvendigvis er begrenset til den foran i detalj beskrevne og på tegningen viste utførelsesform, idet det kan tenkes en rek-ke modifikasjoner innenfor oppfinnelsens ramme. It will be understood that the invention is not necessarily limited to the embodiment described in detail above and shown in the drawing, as a number of modifications are conceivable within the scope of the invention.
